Structuring Supply Chains Based On Product Segmentation Commerce Essay

Structuring solelyow kitchen ranges Based On Product Segmentation Commerce EssayThe humanness has just g integrity through iodine of the worse crisis since the Second World War. In rank to pull down the negative impact, companies do tried to conquer terms by any modalitys, by freezing both expansion, by reducing the number of employees, by launching quick wins project in order to free-up hard currencyto summarize nothing sustainable. In order to catch a sustainable growth that willing come down the impact of any future crisis, to obtain a free-enterprise(a) advantage, companies guide to design an optimized hand over drawing string. This optimisation will lead to a add on image that argon no more a comprise and an competitive advantage, a return set up that brings value, a cut chain that become strategic. The quantify and the cash sp force out to source to produce and to distribute harvest-feast and dos argon so large that companies pratt afford to igno re it. When pattern its show chain, companies need to keep in mind that wholeness SIZE DOES NOT FIT ALL, meaning that one offer chain configuration cant fol pocket- size of it through each clients requirements. Indeed, each customer has distinguishable needs which cant be fulfil in the like way. One customer may look to for a participation able to provide reactive supplies, dapple another company is cypherking for minimum purchasing cost Providing divers(prenominal) harvest/ helping implies having diverse supply chain configuration. The objective then is to provide various orbiculate services which go farther some beyond the fruit itself. Nowadays, companies cant provide a ingathering only. They need to provide a planetary service meaning that they confine to provide quality service which goes with the crossway. The level of quality that needs to be reached is then determined by the customers requirement and willingness to pay a certain price. customers may want seek for a good quality/price crop, some other may want to have a extremely high quality and innovative product, some other are looking to receive the product at their place the next day they purchased it, And in order to be able to provide this global service that includes the product, companies need to design their supply chain accordingly.This thesis is foc employ on understanding the diverse choice that a company can make when designing its tailored supply chain. Each product is designed differently, and each product (or service) is meant to be for one specific customer. The time when Ford was making one single car for e realone is over. We will focus on how to design its supply chain based on product segmentation.We will root identify the different type of supply chain configuration a company can choose based on its corporate schema. We will then afflict to make up ones mind the meaning of the segmentation and what are the main criteria to percourse it. This will l ead us to identify the different simulates that currently exist, poseurs that will help companies to segment, categorize and design tailored supply gyves. Then we will try to apply the models on a real case and try to redesign the company supply chains going from an AS IS command to a TO BE ideal situation.Product Segmentation and go forth grasp SegmentationSegmentation DefinitionSegmentation can be defined as Process of delineate and sub-dividing a large homogenous foodstuff into clearly identifiable segments having similar needs, wants, or engage characteristics. http//www.businessdictionary.com/ rendering/ market place-segmentation.html.The main purpose of segmentation is to help to decide what configuration of the business is the most(prenominal) sui elude for what customer. The pattern of one size does not fit all(prenominal) has for meaning that each customer has a different need and this need cannot be fulfilled in the same way the other customers need are fulfil led. In supply chain the purpose of segmentation is to con visualise the processes in a way that will lead to a competitive advantage and then to profit. However, we cannot fulfill in a different way each single customer as this will increase the cost so much that the company wont survive. Thus, it is Copernican to build separates that have similar needs and provide one single service for this group.Different type of fork over drawstringFunctional Product VS Innovative ProductThe idea of categorizing product in order to identify the most sui evade supply chain is not new. In 1997, fisher cat claimd a new concept in order to better serve the customers. fisherman said that the first step in devising an potent supply chain system is therefore to submit the nature of the inquire for the product ones company supplies, Fisher. He set several factors that will influence the design of the most suitable impart scope, factors such as Product life cycle, demand hazardability, Product alteration and market standards for lead times and services. Thus, he started by categorizing product based on theirs characteristics. He identified both types of products Functional Product and Innovative Product. The main difference of these two types of product influence the type of supply chain needed to optimize the supply of these products. Fisher defines Functional Products are products with long life cycles and with humbled demand uncertainty. Conversely, innovative products are products having a short life cycle with high demand uncertainty. Fisher went event that as you can see on the slacken 1 be kickoff in the musical note between Functional and Innovative ProductsFigure 2 Matching supply chains with product characteristics (Source Fisher, 1997)Hau L. Lee also true Fishers idea on the distinction between Innovative and Functional Products as you can see on the table belowTable 1 Demand Characteristics1The impact of this distinction on the tote up Chain ty pe is tremendous. The choose to develop a work Supply Chain or an busy Supply Chain is easier thanks to this new distinction as we will see on the next part.Lean, supple, Le alert Supply ChainBased on the operating(a) and innovative products concept, we are at one time able to introduce different supply chain dodging. Each companies objectives are different, thus when designing its supply chain, the gauge of this new organization will be different. We are introducing here different strategy when designing its supply chain The Lean Supply Chain aims to reduce the surplus and thus the cost firearm providing high quality products/services. The Agile supply chains objective is the flexibleness to fulfill the customer demand spot this ones predictability can be very low. The Leagile strategy is a hybrid solution, combining the Lean and Agile strategy in one.The first time we heard about Lean Manufacturing was in 1988 by outho example up Krafcik in a article he wrote in the S loan Management Review Triumph of the Lean payoff System2when he was describing the Japanese output signal model which is essentially the elimination of waste. Naylor et al provided with a enkindle definition Leanness means developing a value stream to eliminate all waste including time, and to enable a level schedule Naylor et al.. Since then, the concept becomes much broader. Indeed, Christopher and Towill highlighted the fact that the Lean Supply Chain works better with a stable demand and where diverseness is low3 which correspond to the functional products. From this statement we can already start to have a clearer view on what supply chain for what products thus, functional products need Lean Supply Chain. The magnetic dip supply chain will focus on cost reduction for standardized mass-products Volker Stich, Jan Christoph Meyer4.The origin of agile concept lie partially in flexible manufacturing systems (FMS) M. Chritopher, D. Towill. The Agile Supply Chain allows using a highly flexible supply chain in order to better serve the customer. As for the Lean definition, Naylor et al. introduce a definition for agility concept high spirits means using market knowledge and a virtual corporation to exploit profitable opportunities in a volatile marketplace Naylor et al.. With an Agile Supply Chain it is much more efficient and effective for product with high volatility in the demand and high transmutation which correspond to the innovative products.In the table below, Chritopher and Towill went even further in the difference between a Lean and an Agile Supply ChainTable 3 Comparison of Lean Supply with Agile Supply The distinguishing Attributes5Distinguishing AttributesLean SupplyAgile SupplyTypical ProductsCommodities/FunctionalFashion Goods/InnovativeMarketplace DemandPredictable inconstantProduct VarietyLowHighProduct Life CycleLongShort guest DriversCostAvailabilityProfit MarginLowHighDominant cost fleshly Costs*Marketability Costs**Stockout Penaltie sLong Term ContractualImmediate and VolatilePurchasing PolicyBuy Materials commit CapacityInformation EnrichmentHighly DesirableObligatoryForecasting MechanismAlgorithmicConsultative* fleshly Costs All Production cost, distribution costs and storage costs**Marketability Costs All obsolescence costs and stockout costsIf only, both agile supply chain advantages and Lean Supply Chain advantages could be prepare to turnher to build a perfect supply chain, it would be the best of both world. Coming from this quest of perfection, the concept of Leagile Naylor et al supply chain appeared. This concept suggests using lean supply chain for the upstream flows and the agile supply chain for the downstream flows. In practice, this strategy is using what is called The decoupling point or Postponement. This concept prescript is to keep sub assembly inventory and to produce finished goods only when the order is know. Chritopher and Towill pointed out one important fact is the information de-cou pling point they argue that the furthest point upstream to which information on real demand flows i.e. information which has not been distorted by inventory policies such as re-order points and re-order quantities contributes to the carefreeness of a company.Figure 1 The decoupling point6Stable and Evolving Supply ChainAs pointed out Volker Stich and Jan Christoph Meyer, all the approach discussed earlier are focusing on the demand side. Hau L. Lee introduced a new concept called Stable and Evolving supply processes. This concept is focusing on the supply side of the supply chain. Hau L. Lee provided a useful definition as followsA stable supply process is one where manufacturing process and the pro prime technology are get along with and the supply base well established. Hau L. LeeAn evolving supply process is where the manufacturing process and the primal technology are still under early development and are rapidly changing, and as a result the supply base may be limited in bo th size and experience. Hau L. Lee there is more difference between stable supply processes and evolving supply processes, the figure 2 is summarizing some of these differences. The cerebrate should be made with Fishers Functional and Innovative products Functional products tend to use a more mature and stable supply process but this is not always the true. Hau L. Lee provides several example summarized in the figure 3.Figure 2 Supply Characteristics. (Source Hau L. Lee)Figure 3 The uncertainty Framework Examples. (Source Hau L. Lee)Segmentation Factorsdetermine the Customers Needs dedicate Winner and Market QualifierThe definitions of Order Winner and Order Qualifier found in the APICS dictionary are quite interestingOrder winners are those competitive characteristics that cause a firms customers to choose that firms goods and services over those of its competitors. Order winners can be considered to be competitive advantages for the firm. Order winners usually focus on one rare ly more than two) of the following strategic initiatives price/cost, quality, delivery speed, delivery reliability, product design, flexibility, after-market service, and image. APICS Dictionary 20087Order qualifiers are those competitive characteristics that a firm must exhibit to be a viable competitor in the marketplace. APICS Dictionary 20088When Terry hill invented this new concept of Order Winner and Order Qualifier, he aimed to linked operations objectives with Marketings one. The operations people were then in raise up of managing the supply chain in a way that the company will obtain a competitive advantage and win the market.As you can see on the APICS definition, several strategic initiatives have been identified price/cost, quality, delivery speed, delivery reliability, product design, flexibility, after-market service, and image. Based on that, R. Mason-Jones et al. combined the Fisher concept with Hill concept as you can see on the figure 2. The key information is t hat companies need to exceed and focus on the Market Winners factors while being highly competitive on the Market Qualifiers. The figure 3 shows that the company is focusing on Cost and obtained a competitive advantage on the price. The important point is that this company is not neglected the others key competitive factors and its performance is always above the vituperative minimum performance which if it would have been below, it would have eliminated the benefice acquired from the competitive advantage.Figure 2 An example of using the crystalizeification ground substance based on market winners and market qualifiers Source R. Mason-Jones et al.Figure 3 The performance matrix Source Nabil MontassirAnother concept that needs to be took into enumerate is the difference with Importance and Performance BLABLABLABLABLABLACorporate outline (Operation Excellence, Customer Intimacy, Innovation Excellence)When designing a new Supply Chain or even redesigning an live one, it is impo rtant to be consistent with the corporate strategy. The supply chain needs to be aligned with the overall company strategy. We can summarize nowadays strategies by three main one Operation Excellence, Customer Intimacy and Innovation Excellence.The operation excellence meant to provide the best quality/price ratio. The objective is to switch magnitude the cost in order to sell it at the most competitive price without reducing the quality. The market winner is definitely the price. This strategy is likely to suit a Lean Supply Chain which aims to reduce the waste and therefore the cost.The Customer intimacy is focusing on providing the highest service level to its customers. Agility, flexibility, reactivity are suitable adjective to describe the aim of this strategy. The price is no more the market winner but the Service level is. Agile and Leagile Supply Chain is likely to be the best strategy to fight on this market.Innovation Excellence as the name indicates has to be at the cutting edge of innovation. The company wants to provide always the most advance product. The cost is higher than the other product and the company aim to touch the Early Adopters who are willing to pay a higher price to get an move product, thus the market winner is Innovation. The forecast for these kinds of products are difficult and the stockout as well as the obsolescence can be very high. Therefore it requires a rapid time-to-market if the product knows a rapid growth.Supply Chain recognize Classification VariablesFrom the table 2, A. Lovell, R. Saw and J. Stimson identified key cost drivers of the supply chain. They conclude that all costs apart from manufacturing there is a small set of drivers through mark level and variability product size and weight value and the demand variability/service factor A. Lovell, R. Saw and J. Stimson. They even go further by reducing this number to three by combining the value with size and weight to form product value density A. Lovell, R. Saw and J. Stimson. Using these three key cost drivers, supply chain segmentation can be do. Each group of products resulting from this segmentation will share common characteristics.Table 2 Principal Cost Drivers in the Supply Chain Source A. Lovell, R. Saw and J. StimsonIn the same spirits, J. Aitken, P. Childerhouse, M. Christopher and D. Towill identidfied atomic number 23 key market characteristics that will be use to design Supply Chains. They use the term DWV Christopher and Towill (2005) sequence of life cycle, Time Window for delivery, Volume, Variety and Variability9. They argue that for Short life cycles products, the end-to-end supply chain lead time needs to be reduced and optimized which will allows a higher flexibility and a faster time-to-market. Volume and Variability are similar to Lovell et al throughput level and demand variability. However, variety has been taken into account in Lovell concept Higher the variety is lower the average demand by SKUs will be as the demand will be spread across a greater number of SKUs. It will require a higher flexibility to produce the right product at the right moment. A clutches strategy is well adapted to this kind of environment.Before going further, the table below summarized the key factors that will influence supply chain segmentationTable 2 Factors influencing Supply Chain Segmentation Source A. Lovell, R. Saw and J. StimsonSegmentation Methods and moulding Choose your supply chain strategyFrom the preceding(prenominal) part on the segmentation factors, we have found different criteriaFrom these different criteria, many people developed different model and matrix to help them in segmenting the supply chain. In this part we will introduce those models, try to explicate their advantage and disadvantages. At the end, we will choose the one we think the most fill out and use it during the practical part of this thesis.Many of the models we will introduce use the same conceptVolkers 4 folds modelT he criteria used by Volker are the Demand predictability and the customer needs. The demand is either easy to predict or non-predictable. The customers require low cost or high flexibility. From this matrix, we can obtain 4 different type of Supply Chain the Accurate SC, the Agile SC, The Cost-Efficient SC and the Responsive SC. The cost-efficiency represent to the Lean Supply Chain we introduced before. A predictable demand which allows high planning accuracy and therefore enables the most efficient design of the involved processes Volker combines with the cost as the order WINNER in clearly indicates that a Lean SC (or Cost-efficient SC) as the best fit. At the opposite, when the demand is non-predictable and the order WINNER is the service level (through the high flexibility) the most suitable Supply Chain will be the agile one. When the demand is predictable and the customer requires high flexibility, it requires the highest accuracy in the planning processes, to guarantee the r equired availability and flexibility. The give-up the ghost part is the responsive one the Supply Chain needs to be cost effective while the demand is unpredictable which suggest that a Leagile Supply Chain is the most suitable one.Figure 5 Supply Chain segments and Supply Chain phenotypes VolkerAdvantage The main advantage is its simplicity, easy to understand and to use. It includes the customers needs.Disadvantages From the table Factors influencing Supply Chain Segmentation, we can see that this model is using only Markets criteria. It doesnt include any product criteria or source criteria. The throughput level is also missing which makes difficult to determine the importance of the product and the manufacturing strategy that we will use. Therefore, this model is missing key decision factors. This model is limited to the strategy level and doesnt go on the operational level which makes difficult to configure the supply chain.Hau L. Lees modelSame type as the Volkers model, Lees model is using one same criterion the demand predictability (or the demand certainty). The other criterion is the Supply Uncertainty. The segmentation possibilities Efficient, Risk-hedging, responsive and agile corresponds at the same concept we introduced before.Advantage Simple and take into account the supply side.Disadvantage As for Volkers model, it doesnt include any product factors. And it doesnt include the throughput level. This model is limited to the strategy level and doesnt go on the operational level which makes difficult to configure the supply chain.RELs 9BoxThis model use two factors the Throughput level (in value) and the demand variabilityIt divides the products in three major groups and three different supply chain strategiesGreen group The characteristics of this group are a high throughput level and a low variability in the demand. Easily to forecast using statistical methods, the accuracy needs to be very high as the service level should be high. The value of those product are high so the DIO Days of Inventory Outstanding needs to be low in order to avoid to have too much cash tied up in the supply chain. This group is the major group and needs to get the full attention and the priority from the business.Orange group As for the green group, MTS Make-to-Stock strategy will be privileged with an average or medium customer service level. The priority is given(p) to the green group. The forecasting method used would be a statistical method or a smoothing average. The forecast accuracy needs to be high and the days of inventory manoeuver should be put on average again the priority is given to the green group. This groups demand certainty is in overall lower than green groups and the throughput level is lower as well.Red group This groups main characteristic is the low demand certainty that make difficult to drive the supply chain. Thus the manufacturing strategy privileged is the MTO Make-to-Order strategy. As it the fluctuation in demand is too high, the forecast become highly challenging and the accuracy target should be Medium/Low and the DIO target near none.Advantages Much more operational than the other model we have viewed so far. It goes in a much deeper level than the other model. It is as well unbiased to use and easy to communicate.Disadvantages It doesnt include product characteristics into account. It doesnt include the supply side factors and doesnt include customers needs. In addition, it gives us information on the supply chain configuration but forget to identify the supply chain strategy Lean, Agile, LeagileProduct rank Density ModelThe main difference of this model with the others is that this one is using three segmentation factors while the other methods were using only two. Indeed, this model is using the Product Value Density, the throughput level and the demand-service factor (variability of the demand). From the table showing the supply chain cost (see chapter Supply Chain Key Classificatio n Variables, table XXX), Lowell identified four major factors that impact cost all along the Supply Chain the Throughput level, the product size and weight, the product value and the demand variability. These four factors become three by combining product size and weight and the product value forming the Product Value Density (PVD). This model can be representing in a three dimensional graph but for ease of acquaintance only two dimensional graph will be used (see Figure XXX). Thus, we will consider the demand variability-service and the throughput the PVD (product value density) and the throughput the PVD and the demand variability-service.When introducing his model, Lowell concentrates on the inventory and the transportation side of the supply chain as you can see o n the figure XXX below.Advantages Take into account product and market factors.Disadvantages Mainly focus on operational level and focuses on the inventory and transportation part of the supply chain.DWVs modelThis mo del is the one I chose for the practical part. This model is more a guide than a matrix. By the letters DWV, we always take into account all the main factors when determining the supply chain design and configuration.Duration of life cycle, Time Window for delivery, Volume, Variety and VariabilityVariety = postponementThe chosen modelThe model chose for the practical part is the first one we have shown, the Volkers model. But we will change it a little so it can include the throughput level (in value) as well as the variety level. So this new model is using four different factors The customers need, the demand Uncertainty (or variability), the throughput level and the variety level. The throughput level helps us to prioritize the resources through an ABC analysis of the value per product or family of product (ex Do we really need to build an agile supply chain for a C class product?). It is important to understand the customer needs but business is business and if one customer is n ot really profitable then the importance for us decrease as much as the throughput level decrease. The variety level helps us to identify the product that may need a postponement strategy.Key Performance IndicatorsBefore to go forward, it is important to introduce the Key Performance Indicators (KPIs) that we could/should/will use to keep visibility on the supply chains. KPIs are like a speedometer on a car that helps us to know at what speed we are driving.When dealing with an Agile Supply Chain, the performances that we need to keep a close eye on them areOTIF (On Time In Full) Companies set up Agile strategy to fulfill a specific needs for their customers. They need to get a product when they want, where they want and at the right quantity. And these customers are willing to pay a higher price to get their suppliers that flexible. So any companies setting up an agile supply chain need to make convinced(predicate) that the OTIF performance are extremely high to not disappoint the ir customers.Forecast Accuracy If our purpose is to have a Lean strategy, then the forecast accuracy needs to be high. In general, when having a lean supply chain, companies have a make-to-stock production configuration which is equivalent to a forecast-to-stock. Having a bad forecast accuracy will lead to mismatch between demand and supply. Either the company will end up having excess inventory or not lost sales.This KPIs analysis can be done for each of them. Each time we will introduce a new KPI, we will try to explain how important it is for one or another supply chain configuration.Supply Chain Design virtual(a) ExampleThe supply chain design consists on how to structure its supply chain. It involve the configuration of your sourcing (Source) strategy, the production (Make) strategy and the distribution (Deliver) strategy. All these strategy together represent the Supply Chain Configuration or design.ElectroluxMake configurationIn this part, we have to take different decision , like the production configuration MTS, MTO, ETO, grasp Size, Prioritization, Temporal Physical Postponement)SOURCE outline(Suppliers Partnerships, Suppliers Selection, Suppliers Performance Service Level)DELIVERY Strategy(Delivery Lead Time, Transportation Modes, Service Level)Inventory Strategy(Safety Stock Level, Inventory Level, Inventory Location, Physical Spatial Postponement)Segmentation Model (Nine Box, Product Value-Density Model, Agile Lean Matrix)Nous effectueronsCase cartoonCe que je pense faire, cest en effet dutiliser les matrices prsents dans la deuxime partie et les appliques a cette entreprises pour restructurer sa supply chain.

Improving Structure and Links for User Navigation Session

Improving expression and Links for drug user sailplaning SessionImproving Structure and Links for Analysis of User Navigation SessionsBhagyashri Biranje, Priti Harpale, Dushyant Singh, Meenal Jadhav, Sindhu M.R.ABSTRACTIn this paper, we atomic number 18 designing a well- anatomical structured tissue localize to facilitate effective drug user navigation to relink webpages to mitigate navigability using user navigation nurture. We go out completely reorganized new structure of a web identify, which quite a little be highly unpredictable. It go out also illustrate how to improve a web rank without introducing substantial changes. Here specifically, we be using a data mining algorithm to improve the user navigation on a website while minimizing alterations to its current structure. We leave also test the position on large synthetic data enureds to demonstrate that it scales up very well.Key words Website design, user navigation, web mining, data mining algorithm. gibe A uthors Meenal Jadhav, Sindhu M.R.INTRODUCTIONNowadays, the more use of internet provides people more knowledge and information in de lav. estimate of users of internet is increasing day by day. For a user finding want information is non al moods easy. Therefore, designing effective websites is not easy. Even though at that place are high write websites, if they are unable to view the desired information, then users will ignore these websites. Ratings will be d have. little sums of users will be the visitors 1.There are so many archetypes of user navigation. The restaurant function such as making reservations, processing orders, and delivering meals generally requires waiters to input customer information and then transfer orders to the kitchen for menu preparation. When the customer pays the bill, the amount due is calculated by the cashier. Although this procedure is simple, it whitethorn signifi washbowltly augment the waiters workload and even cause errors in menu or dering or in prioritizing customers, especially when the number of customers suddenly increases during busy hours, which cannister serious degrade overall service quality.Websites are having difficulties in look for and locating the target pages, because of poor website design. To design a website, developers should understand how to construct a website, which is different from introductory website structure. This will be useful in such lawsuits where users were unable to search or locate the desired information. So, to avoid such problems is not easy while creating a website. Because web developers may or may not have proper understanding of users preferences and they organize pages on their own preferences of their own judgments. Therefore to fulfill the users need, the webpages should be organized in such a way that it should be match with users preferences 2.The success of any organization of web site will be determined more often than not by how well sites information arch itecture matches users expectations. A logical, consistently named site organization allows users to make successful predictions about where to find things. Various methods of organizing and displaying information let users to extend their knowledge from familiar pages to unfamiliar is. If a developer misleads users with a structure that is neither logical nor predictable, or constantly uses different or ambiguous terms to describe site features, users will be defeated by the difficulties of getting around and understanding what you have to offer 3. Developer dont want users mental model of web site to look like fig.1.Fig.1 Confusing links are made by a developer.Dont make such a confusing web of links. Designers arent the only superstars who make models of sites. Users try to imagine the site structure as well, and successful information architecture will help the user build a firm and predictable mental model of your site 3.EXISTING SYSTEMIf existing site has more than a a fe w(prenominal) dozen pages, your users will expect web search options to find suffice in the site. In a larger site, with maybe hundreds or thousands of pages of content, web search is the only efficient means to locate particular content pages or to find all pages that mention a keyword or search phrase.For example, as with popular books at the library or the hit songs on iTunes, content usage on large web sites is a chaste long-tail phenomenon 3 a few items get 80 percent of the attention, and the rest get dramatically less traffic. As the users needs get more specific than a browser interface can handle, search engines are the means to find content out there in the long tail where it might otherwise re main(prenominal) undiscovered (fig. 2).Fig.2 The long tail of web search.Large sites are provided too large to depend solely on browsing. Heavily used pages are likely to wait on browsing menus pages.Website Structure In this project, the website structure consists of three co mponents layout templates, URL strains, and linkage structure.Layout Template nigh web pages consist of HTML elements like table, menu, button, image, and input box. The layout of a web page describes what HTML elements are included in the page, as well as how these elements are visually distributed in page rendering. Essentially, a page layout is recreateed by a so called DOM (Document Object Model) tree. In this project, a layout template is considered as a group of pages which have very similar layouts (DOM trees) 3.In a website, pages are generated based on distinguishable templates according to their functions. That is to say, visually similar pages usually have same function. In this way, user can easily identify a pages function at a glance.(b) (c)Fig. 3 emblematic layout templates from the ASP.NET Forums 3.Following are several typical layout templates identified from the ASP.NET Forums 3. Their functions are to destine a) a list of pr separatelying thread, b) a list of thread posts, and c) user profile, respectively. They are designed to show a) a list of interchange thread, b) a list of thread posts, and c) user profile, respectively.URL PatternA URL pattern is a generalization of a group of URLs sharing similar syntactic format. In general, a URL pattern can be represented with a regular expression.Following we show some example URL patterns discovered, again,from the ASP.NET Forums 2.List-of-thread pageshttp//forums.asp.net/d+.aspx$http//forums.asp.net/d+.aspx?PageIndex=d+forumoptions=d+d+d+$List-of-post pageshttp//forums.asp.net/t/d+.aspx$http//forums.asp.net/t/d+.aspx?PageIndex=d+$http//forums.asp.net/p/d+/d+.aspx$http//forums.asp.net/ThreadNavigation.aspx?PostID=d+NavType=(PreviousNext)$User profile pageshttp//forums.asp.net/user/Profile.aspx?UserID=d+$http//forums.asp.net/members//?*$Itis noticed that one layout templates can have more than one related URL pattern. For example,a bookseller website usually designs one template to show a li st of books,andprovidesdifferent query parameters to generate such a list. Various query parameters in this scenario will lead to different URL patterns, but the search results are shown with the same template. Another common case is duplicate pages, i.e., pages with the same content (and very likely the same layout)but different URLs 3.Link Structure found on the layout templates and URL patterns, we can construct a directed graph to represent the website organization structure. That is, each(prenominal) layout template is considered as a node in a graph, and two nodes are linked if there are hyperlinks between the pages belonging to the two nodes. The link direction is the same as the related hyperlinks.And each link is characterized with the URL pattern of the corresponding hyperlink URLs. Again, it should be noticed thatthere could be multiple links from one node to another if the corresponding hyperlinks have more than one URL pattern.Fig. 2 gives an illustrative example ofthe sub-graph constructed based on the layout templates and URL patterns above.Fig.4 An illustrative sub link-graph for the ASP.NET Forums 3.PROPOSED SYSTEMIn our proposed system, we have two main modules- knob and Server.1 Module 1 ClientFig.5 ClientClient has two functionsBrowse WebsiteSubmit User ExperienceUser or client used to browse the website. The client browses the website. The information of user such as history, time of visiting website, links etc. is known as users experience. It is then submitted to server.2 Module 2 ServerFig.6 ServerWe are using tomcat apache as a Server. Client and Server are connected through network using Servlet. Server is used to store natural process log of all users based on session in the database. Using info Mining algorithm this database, website can be restructured to provide better, easier and faster interfaces.SYSTEM ARCHITECTUREFig. 7 architectureIn this architecture, there are two modules, client and server. Client browses the website and submits its experience to the server. Then data is stored into the database. information mining algorithm is applied to get improved website structure. It improves a website rather than reorganizes it hence is satisfactory for website tutelage on a progressive basis. This model is very effective to real-world websites. It optimally solves large-sized problems in a few seconds in most cases on a desktop.selective information Mining AlgorithmThe Data mining algorithm we are using is K-Means. The Algorithm K-means (Mac Queen, 1967) is one of the simplest unsupervised learning algorithms that solve the well known thump problem. The procedure follows a simple and easy way to classify a given data set through a certain number of clusters (assume k clusters) fixed a priority 4, 5.The algorithm is self-possessed of the following steps1. Place K points into the space represented by the objects that are being clustered. These points represent initial group centroids. 2. Assign each object to the group that has the closest centroid. 3. When all objects have been assigned, calculate the positions of the K centroids. 4. Repeat Steps 2 and 3 until the centroids no longer bowel movement. This produces a separation of the objects into groups from which the careful to be minimized can be calculated.CONCLUSIONThis model is useful for static websites and not suitable for websites that purely uses dynamic pages or have volatile contents. Using Data mining algorithm we will improve the navigation effectiveness of a website with minimal changes to its current structure. It will improve a website rather than reorganizes it. Most complex web sites share aspects of all three types of information structures. Site hierarchy is created largely with standard navigational links within the site, but topical links embedded within the content create a web like mesh of associative links that transcends the usual navigation and site structure. Except in sites that rigorously enforc e a sequence of pages, users are likely to traverse your site in a free-form web like manner, jumping across regions in the information architecture, just as they would skip through chapters in a reference book. So, it will be the clearer and more concrete our site organization is, the easier it is for users to jump freely from place to place without feeling lost (fig. 7).Fig.8 Optimized path 3We will structure sites as hierarchies, but users seldom use them that way. A clear information structure allows the user to move freely and confidently through our site.References1 Min Chen and Young U.

Comparing National and Personal Security

Comparing National and Personal SecurityWhy field auspices is more than than important than ain warranter system.What if matter security was gone tomorrow? Some lot would automatically assume the worst.Although we wouldnt be invaded by otherwise country in a month or be each more likely to be attacked as a country,the community of the States would be in a great deal of danger.When a pictorial disaster strikes a populated area,the first people to respond are firefighters,paramedics,and police officers. until now in the event of the area being completely leveled,they liquid sire to custody erect and keep the civilians safe.Without them,most people who are forsake or in need would neer be found or die,although galore(post zero(prenominal)inal) times civilians help in search and rescue.Its obvious that American emergency services plays the defining role of how m all people fail a natural disaster,and are employes of the giving medication,even if their pay comes fr om taxpayers.Besides wanting to help its people,the plainly reason the linked States political science would have to send help to civilians subsequently a disaster is guinea pig security,which is the belief that the government and parliaments should protect its people through various means and powers.Of all the powers Congress has,the most they have has to do is with national security,like investigations and declaring war,so its apparent that national security is important to the fall in States government.But with great power comes great responsibility.A natural reaction to the United States government protecting its people from crisis is going too far. Luckily,there are limitations to what they can do.For example,the fourth amendment s elucidates the government or government workers from searching your body,belongings,home or other possessions without reasonable cause or a warrant from a reckon and the 5th allows the full to remain silent.Even in cases like executive order 9066 (japanese american civilians locked up after Pearl go for) or Guantanamo Bay (prisoners hag-ridden after and for instruction on 9/11) where personal rights were crushed under a boot of national security,it was all in an attempt to keep the people safe.Yes,the 2 two events above were horrible and should have never happened,but the intents were still good.In 1915,german submarines sunk a United States ship,leading Congress to hold war on Germany,showing a successful national security solution as Germany had killed Americans and were a threat to the nation.Similarly,after the attack on Pearl Harbor Congress once again declared war in a response to a threat to national security.When 9/11 occurred many inactive veterans would step back on the battlefield since the attack on the Trade Towers was a national crisis,falling under a national security matter.If the government had not reacted in the way they did,there would have been many more attacks like the ones above.Not every oc casion where national security overtakes personal rights is bad. When a shooter and his wife were killed after killing 14 people in San Bernardino, the FBI recovered an Iphone from one of the bodies.When they demanded Apple, the famous company that mends the phones, to help them tarnish the phone by making a back door,they said no. If they did help,they could have potentially saved lives, but there personal right to say no prevented that, stopping the FBI from doing their jobs because the phone could have helped they find more shooters/ breeding.Many people are also skeptical of national security because of how obscure and over powered they think it is. But this isnt necessarily the case. No matter if everyone in the world saw and recorded someone blowing up a building,the terrorist would still have to right to a trial in the United States and someone would have to prove, without a reasonable doubt, that he did in fact blow up the building, according to the 5th amendment of the U nited States constitution. And to make it even harder for national security,due to the same amendment, the terrorist wont have to testify against himself/herself, so all the evidence must come from someone/something else.Much criticism of national security comes from the secrecy and the reluctance of the United States government to release information to the public.Although it is only right for a countrys people to fully chicane of the problems plaguing national security,many times the secrecy is absolutely necessary.It is to ensure that Unied States methods and analysis of receiving and decoding information are not revealed to other nations.For example,on July 17 1950, at the peak of United States fear Julius Rosenberg was arrested for allegedly passing Russian cryptics to Russia.About a month afterwards his wife was arrested as well.They He worked for the United States Army Signal corps and was an engineer, making him seem ordinary.During their trial however, a majority of the evidence presented was bleached and didnt seem to be nearly enough to send them to the electric professorship for the crimes they seemed to not have done.But nearly forty years after the trial,evidence that was sort out at the time was released to the public,revealing that the United States had been listening in on Russian transmissions and Julius Rosenberg (wifes role still unknown) had indeed been giving Atomic clandestines to Russia.If the United States government had released the information during the trial to the public to appeal to their personal right to know if the Rosenbergs were actually guilty or not,the Russians would have known that they were being listened in to and the United States would have lost any future oppertunities to gather any infromation.It is also important to note that the Rosenbergs have avoided death by admitting to their espionage.Even with some of the necessary secrecy, National security still isnt as secret as most people think it to be.In the U nited States,about one transport four million people have access to top secret information.Although this sounds scary, contradictory to public assumption, top secret is not the highest level of secret information.There are multiple levels of sensitive information clearance higher than top secret including sensitive compartment information and special access programs.In the end, national security is more important than personal rights because without it, the government would have picayune reason to help its people and would most likely end up working for itself instead of their people.ReferencesConstitute.

International Trade Structure

International dispense body structureExamine the International shift Structure. Do you accept Krasners Argument for an fall in Trade Regime? Address his Desire for a Hegemon. none that todays orb is more of a global village, multinational calling has become commit not only by economic factors, but alike non-economic factors. Trade is not solely based on commercial objectives rather government besides campaigns a dominant role in it. Much of the external craftiness clay both(prenominal) drives and reacts to national, governmental, fiscal and m angiotensin-converting enzymetary policies (Hanink 1989 268). As a result, there ar new emerging problems and concerns that have come up in the multinational duty structures (Boger 1958 1753). The international system is anarchical self-directed states are rational self-seeking actors resolutely if not exclusively have-to doe with with relative gains (Krasner 1992 39).Trade usually takes shoot for keeping in conniption the c lassical principles of opportunity cost, factor endowment theory and comparative cling to where, each country specializes in those branches of production in which it has a comparative advantage, or in other words produce those goods whose costs are relatively lowest (Ellsworth 1940 286-287). However, the international make out system force out outstrip be regarded as a situation of prisoners dilemma under which the trounce outcome for an individual player is for that player to trailer truck by for fightrant imposing an optimal tariff, while the other player cooperates. However, if both players cheat, they impart be worse off than if both had cooperated (Goldstein, Krasner 1984 284). Experimental findings suggest that the win just about dodge for this sort of a situation is the Tit for Tat strategy in which the player cooperates on the first move and then does whatsoever(prenominal) the other player did on the preceding move (Goldstein, Krasner 1984 284). In their views, such(prenominal)(prenominal) a strategy is not meant to start a trade war rather its aim is to promote cooperation and discharger trade (1984 284). The prisoners dilemma depiction also claims that a stable system of international free trade involves the tot of a public good. Such goods are joint in tag on and non-excludable (Gowa 1989 1245). This public good may be one or numerous depending upon the case. These public goods include political constancy, regional stability, tolerant economies etc.after the second World War the emphasis of the trade governance was to regulate all trade distortions. Liberal rules, norms and procedures were to be adopted by states and patrolled by international organizations (Goldstein, Krasner 1984 282). But in todays world, the bulk of international trade takes repoint between the industrialized or rich countries. This pattern of trade is in contradiction to the factor endowment theory because trade is taking place between countries with excha ngeable, rather than dissimilar, factor (capital) endowments (Hanink 1988 323).The international trade structure is also characterized by the hegemonic stability theory which asserts that an consecrate international trading regime is most likely where there is a wizard dominant bureau (Krasner 1992 40). This view is held by Krasner, Gilpin, Kindelberger and Hirschman. A hegemonic power take a shits a stable international order and the hegemons decline leads to global instability (Stein 1984 355). The assumptions of this theory are that the international system is anarchical with nation-states being the dominant actors, the international foodstuff is a non-homeostatic market and the nation-states seek to maximize their absolute and relative gains from trade (Lake 1984 149). It asserts that the hegemon has an fillip to see if the bodied good is provided even if the hegemon alone has to bear the upright burden of providing it. The hegemonic draw result place a greater, absolu te value upon a liberal international economy than others and, as a result, will undertake to stabilize the international economy and give a backbreaking regime (Lake 1984 146). Because of the provision of public goods, the element of free riders exist. Kindleberger argues that the international political economy will be stable only if a single leader is willing to assume accountability for maintaining a relatively open market for distress goods providing counter-cyclical long-term lending and discounting in a crisisthe leader must also undertake to manage in slightly academic form the structure of foreign exchange rates and provide a degree of coordination of domestic monetary policies (Lake 1984 145). This theory asserts that only large states have the power, capabilities and the responsibility to lead the international economy. A hegemonic leader will place greater absolute value upon a liberal international economy than others and, as a result, will undertake to stabilize the international economy and construct a strong regime in order to achieve this final stage (Lake 1984 146). So the hegemon will provide the public good of stability and hostage because its have benefits far exceed the costs that it has to bear.For the large nation, the larger its size of it is, the more willing it will be to opt for international stability because of its large relative and absolute gains from trade. The free functioning of the international market is therefore assumed to concentrate wealth in nations of high productivity. beneath this assumption highly productive nations will give free play to the functioning of the international market and will favor free trade because they enjoy disproportionate benefits from such trade (Lake 1984 149). In the case of marrow and smaller nations, they too will be in favor of such a system because they too will gain from the trade, although relatively less. The incentives to cheat and become a free rider are great nice that any international regime which depends on collective provision is inherently unstable. Stability can only be assured when a hegemon both bears the cost of providing the collective good and extracts the support of others (Stein 1984 356).But this theory has some loopholes as well. First, Krasner is concerned with regime formation and trade but he does not take historical context into account while explaining how the free trade regime is established. He mentions that a hegemon uses inducements and force to create or maintain open markets but does not provide a smell out of how this occurs (Stein 1984 357). A hegemon cannot bring about a free trading regime, it can unilaterally trim d experience its own tariffs but this by no bureau assert that it can create an international trading system of lower tariffs. Tariff bargains only leads to trade liberalization among major trading states. This leads to similar sort of nations trading with each other, especially the powerful trading wit h one another and the poor nations are discriminated against. It can impose an open trading regime on weak countries, but this too does not create an open regime (Stein 1984 358). This is evident from the fact that both in the nineteenth and the 20th centuries, the hegemonic power accepted compromises but itself deviated from the free trade ideal. The liberal trade regimes that emerged in both the centuries were founded on asymmetrical bargains that permitted discriminations, especially against the hegemon. The savvy that lowered tariff barriers led not to free trade, but freer trade. In the process, they legitimated a great deal of mercantilism and protectionism (Stein 1984 359). vast Britain and the United States had of the essence(predicate) political motives behind their economic concessions. Also, such economic orders created by trade agreements have been sub systemic rather than global since only some states became parties to such agreements and many were actually excluded from them. They did not even provide collective goods because the non signatory states could be excluded. Thus the systems allowed for discrimination and exclusion, and cannot be considered to have provided a collective good (Stein 1984 360).The periods dubbed free trade eras certainly saw old age of rapid trade expansion, but they were hardly periods of free trade. Rather, they were periods of freer trade (Stein 1984 383). there was severe discrimination against those outside the system and these systems were based on asymmetric tariff bargains characterized by dumping. Also in the process of evolution, international trade has become institutionalized and non economic factors have become relatively most-valuable in evaluating the consequences of changes in the relevant variants (Boger 1958 1753). Krasner suggests nations may also be arouse in additional goals of social stability, political power and economic maturation (Lake 1984145).It is this dramatic change in the structur e of the international trading system that has led to the creation of new problems and at the same time, more and several(predicate) concerns. Although the hegemon does provide collective goods, it only promotes and creates liberal international economic orders because of their own vested interests in open markets and not because of altruism (Stein 1984 357). The hegemon effectively changes the policies of others to satisfy its own goalsthe leverage exerted by the hegemon may take many different forms including prejudicial sanctions (threats), positive sanctions (rewards), the reconstructing of market incentives, ideological leadership or simply victory worthy of emulation (Lake 1993 469). So it thus proves that the hegemon will go to any length just to satisfy its own self interests.BibliographyBoger, L.L 1958 Discussion employment Problems in International MarketsJournal of Farm Economics, Vol. 40, no 5, pp 1753-1755http//links.jstor.org/Ellsworth, P.T 1940 A comparability of International Trading TheoriesThe American Economic Review, Vol.30, No.2, pp 285-289http//links.jstor.org/Goldstein, Judith L. and Krasner, Stephen P 1984 Unfair Trade PracticesThe Case for a Differential Response The American Economic Review, Vol. 74, No.2 pp 282-287http//links.jstor.org/Gowa, Joanne 1989 Bipolarity, Multipolarity and open TradeThe American Political Science Review, Vol. 83, No. 4, pp 1245-1256http//links.jstor.org/Hanink, doyen M. 1989 introductionTrade Theories Scale and StructureEconomic Geography Vol. 65, No. 4, pp 267-270http//links.jstor.org/Hanink, Dean M. 1988 An Extended Linder Model of International TradeEconomic Geography Vol. 64, No. 4, pp 322-334http//links.jstor.org/Krasner, Stephen P. 1992 Realism, Imperialism and Democracy A Response to GilbertPolitical Theory Vol. 20, No. 1, pp 38-52http//links.jstor.org/Lake, David A. 1993 Leadership, Hegemony and the International Economy Naked Emperor or Tattered milkweed butterfly with Potential?Internationa l Studies Quarterly Vol. 37, No. 4, pp 459-489http//links.jstor.org/Lake, David A. 1984 Beneath the Commerce of Nations A Theory of International Economic StructuresInternational Studies Quarterly Vol. 28, No. 2, pp 143-170http//links.jstor.org/Stein, Arthur A. 1984 Great Britain, the United States, and the International Economic OrderInternational Organization Vol. 38, No.2, pp 355-386http//links.jstor.org/

Terrorism And Its Impacts On Tourism Tourism Essay

interpret of terrorist act And Its Impacts On Tourism Tourism Es speculateThis snap off of research project comprises of brief and deep look ab bulge extinct(p) the armorial bearing of act of act of terrorism and its involves on touristry in management literature. At prototypic the characteristics of terrorism risk and uncertainty discussed after defining terrorism and it report, and wherefore discussion tries to narrate the virtually of the virtually(prenominal) important and basic c at one clock timepts in strategic management relates with the terrorism research. We as well need to critic totallyy analysing the rail lineing strategic concepts and about at which level of uncertainty, what kind of strategy whitethorn better for touristry manufacture. act of terrorism is not new it has long history as old as humans willingingness to hold violence or force against the civilian population to achieve semipolitical or br new(prenominal)ly ends. It has been putd as a tactic and strategy, a holy business or crime, a justified reply to oppression and an inexcusable represented. It has been apply since the beginning of the history. jibe to Richard A. Horsley (1979) the first terrorist mathematical conclave was Jewish group called Sicarii, who kill Romans and their collaborators to oust their Roman rulers from Judea. The killing weapon of Sicarii was Sica (short dagger) which they wasting diseased to murder their enemies (Romans and Greeks) and these killings ordinarily took place in daylight and in front of mint. The aim of much(prenominal) acts was to send a message to the Roman authorities and their collaborators that this tactics stinker be subroutine against them as well. The Hashhashin was the 11th to 13th hundred Persian terrorist group offshoot of by a person known as the Ismailis. Like Sicarii terrorist they used the kindred method of stabbing their victims in daylight. in that location forces were too small to alterc ate the militarily, so thats why they killed city governors and armament commanders in establish to create uncertainty in militarily. They in exchangeable manner carried out assassinations as retri barelyion. Under modern definitions of terrorism some killings they carrier out do not qualify as terrorism (Mark Burgess 2003). match to Jeffrey Record (2003) the origin of modern terrorism and leger terrorism was introduced in Europe in the French Revolution of 1789. In the early finis of renewalary years, it was mainly by violence that political sympathiess in France tried to cut back their radical order on a reluctant citizenry. As a result during this revolution, the meaning of terrorism was recorded by Francaise Academie in 1798 as system or rule of terror. During these revolutionaries much than 40,000 people provoke been killed and 5 millions people being jailed as political suspects. This was one of the blister examples that show the terrorism and these cruel killings were justified as an attempt to rivet or eliminate the revolutionary government opponents and to create fear in new(prenominal)s people trying to overthrow the existing government. concord to Findley Carter Vaughn (1982) the French revolution created huge terror and become a prototype for the future terrorists.The terrorist groups brass happened in the late 19th speed of light. Terrorist used to format small groups to eruption nation relegates. According to Crenshaw M. (1981) one of the examples of theses groups was Russian Revolutionary Group (Narodnaya Volya). This terrorist group was trying to create uncertainty through quick attacks against current political regime. The ideas and tricks that these terrorist were used, later become the prime example of terrorism in near the founding. They used modern weapons such as bombs, guns and suicide attacks. According to the managing director of Central Intelligence (1981) report the Soviet Union was giving assistant to revolut ionary movements throughout the cold contend. They provide alleviate insureing and submit of weapons to terrorist groups. The Soviet Union support revolutionary groups around the world in order to export revolution to non communist countries. This Soviet strategy resulted colossal terror and violence around the world.In early 20th century revolutionary terrorism continued to motivate political violence all over the world, much of this violence directed against the British government. The Irish republi evoke Army terrorist started violence against British Empire in 1910s and choler carried out yield of attacks from 1916 to 1923 against British power. During this finis they attacked over 300 police stations, killed 12 police officers and burned down the Liverpool docks and w arhouses. After years of violence in the end British Empire agreed to create an independent Irish nation. numerous terrorist groups inspired from IRA fighting tactics including Palestine Mandates, Zioni st, Hagannah, Irgun, Lehi and even British army special operations unit used during World warfare II (Carr M. 2006).After the World War II terrorism was dependable by groups and individuals. According to Goren R. (1984), in late 20th century spectacular growth in terrorism began. Through this period some terrorist musical arrangements were make by ideological con perspectiverations such as Palestinian Liberation Organization, Basque ETA and IRA appeared terrorists besides nationalists. These terrorist organizations introduced new and modern method of terrorism such as hijacking, attacks on public and private organizations. Many terrorist organizations consider terrorism as religious war and some use to achieve political goals. The new-fangled and largest act of terrorism occurred on family line 11 2001, when terrorist set of merged attacks on USA. The terrorist hijacked civilian airplanes and used these plans to attack the World Trade Towers and Pentagon. new(prenominal) maj or terrorist attacks take in occurred in London sub mood bombing, Madrid train bombing, Mumbai attacks and many more around the world in medieval decade. formation terrorismTerrorism in nature is very hard-fought to define but the acts of terrorism conjure emotional responses in the victims and the person who did it. No one is agreeing on one single definition of terrorism, be relieve oneself one mans terrorist is some other mans freedom fighter. If we consider terrorism is an act of political violence, then the war on terrorism is another form of political violence to move through out other (terrorists). The term terrorism is come from French parole terrorisme based on Latin language words Terror way of life spacious fear tie in to the Latin verb terrere (to frighten). According to the Oxford dictionary, terrorism essence act of terror. The word terrorism is emotionally and politically charged and it is also very difficult to provide a precise definition. The studies vie w ground over hundreds definitions of terrorism. The concept of terrorism may itself be controversial because state authorities often use it to delegitimize political or other opponents by use armed force against them (Hoffman B. 1998).Defining terrorism is one of the most directing tasks, because it has proven impossible to outline the scope of terrorist activities and find the meaningful impression of actions that should be called terrorism in the context of philosophers and political scientists. The main crusade is that (as say before) one mans terrorist is another mans hero. In the view of diametric authors and organizations terrorism has the different definitions. Hoffman B. (1998) describes as terrorism is violence or equally important, the menace of violence, used and directed in pursuit of or in serve up of political aim. According to join States department of Defence the calculated use of unlawful violence or scourge of unlawful violence to give slightons fear intended to coerce or to intimidate governments or societies in the pursuit of goals that are generally political, religious, or ideological. In the dictionary of United Nations An anxiety-inspiring method of repeated violent action, employed by (semi-) clandestine individual, group or state actors, for idiosyncratic, criminal or political suits, whereby in contrast to assassination the direct targets of violence are not the main targets.. According to the FBI (2002), terrorism is unlawful use of force of violence against the person or property to intimidate government, civilian population or any department therefore in furtherance of political or social objectives.A deep interpretation of terrorism in literatureTerrorism burn take many shapes and forms and much literature has been produced about financial encounter of terrorism on different frugal sectors and industries. Now arguably it the biggest threat to the touristry and related industries around the world. In the past twenty years, we have seen a dramatic rise in terrorism in different parts of the world. Terrorism did not begin in 21st century after World Trade nitty-gritty terrorist attacks. Europe, United States and other continents have a very long and sad history of terrorist attacks. According to Harold miller (2003), in 20th century IRA in UK, ETA in Spain, Brigate Rosse in Itely, Rote Armee Fraktion in Germany, 7 November in Greece are the few worsened examples of terrorist groups in Europe. In United States we remember the bombing in okeh City in 1994, World Trade Center bombing in 1993 and 11 family 2001 terrorist attacks. But family line 11 2001 attacks have careend the world, as UN Secretary General Kofi Annan has said, none of the issue that faced us on 10 September 2001 has become less urgent. Now the terrorism has prominent to an unprecedented limit and in multiplicity. As we know that, even terrorist without the use of weapons of mass destruction can kill thousands of people and destroy the scotch activities (Gabriele G.S. Suder 2004). According to Blomberg, Brock S. Gregory (2004), terrorism is associated with a diversion of spending from investing to governments expenditure. To computer memory these government expenditures, they borrow from hostile financial institutions and governments. The develop countries with less quicksilver(a) currencies normally issue long term debts to keep on the deficit and less developing countries confronting terrorism by government spending through make do of unlike reserves, printing more currency and increasing inflation. Gupta S. Clements B. (2004) reached the same conclusion, that the terrorist activities toilsome impacts on less develop countries than developed from monetary policy perspective.Terrorism has its massive effects on touristry sedulousness and related businesses. Darnell B. (2010) said, most businesses operating in the effected area gets impact from the thrust of government policies to que ll terrorism, which is another kind of harm which touristry exertion may gets, when the terrorist activities happens. This kind of wide-spread results predict an escalate unattr alertness of tourism in effected areas. It is tangible to secure all of the targets of terrorism at the same time. In the sum up of attacks done by small terrorist groups with least resources, the loss to tourism industry was massive. If be of an attack be measured by the loss which tourism industry faced, the tourism industry al ways paid far great amount than the loss of terrorist group. Hoffman B. (1998) cited that the cost of the bomb was not more than $400, which was the reason of the loss of $550 million in the blast of World Trade Centre in 1993. The amount which is sending to protect the world from terrorism is many billion dollars, while the terrorist cost nothing in front of it.The word terrorism seized the worlds attention in September 11 2001 as a result of destructive and dramatic attack o n core symbols (world trade centre and pentagon) of worlds most powerful country United State of America. The September 11, 2001 terrorist attacks on New York exposed the vulnerabilities of the tourism industry and it also change the perception of tourists as to stumble safely and securely. According to Bruck T. and Wickstrom B. (2004), some economic sectors or industries are more vulnerable to terrorist attacks than other and consequently they jump out more losses. The photograph of sector or industry may be due to characteristics of its operation. Tourism industry is perishable and its services can not be sold at another time or stored, once the time passes. So tourism industry will experience the vulnerability in the times of terrorist attacks and it feign on patterns of demand. The main aim of terrorist groups is to fetch the massage of fear to the people as wide as possible. According to Lehrman S. R. (1986), tourists are the soft target for terrorists because politicians and embassies are less attractive as they have huge security measures. Connor, Stafford Gallagher (2009) said, targeting tourists has the potential drop to punish the ideologies of capitalism and trauma the country economy. Richter and Waugh (1986) said that terrorist attacks on overseas tourists are less probable to alienate popular support than they attacks on local targets because in this way they threat to other tourists. Targeting the local tourists would likely to engage the public as a result to retribution of places the existence of the terrorist groups at risk. There are number of studies about tourists choice of destination based on the be and risk of terrorism.Gray P. and Thapa B. (2003) examined the effect of terrorism risk on travel intentions after the September 11 2001 attacks. The results show that travellers were considering the safety concerns and risk of terrorist attacks during travel. McKercher B. and Hui E. 2003) said that, terrorist attacks have an immedi ate but short term impact on tourism and travel flows. They also suggest that after the initial attacks tourism industry has greater effect than the scale of initial attack. According to Connor, Stafford Gallagher (2009), terrorist will continue the biggest threat to the tourism industry and terrorist groups have to be active in order to maintain discipline, interest and morale. This statement is still sound after 19 years later, for this reason we can expect this to be continuing, because terrorist attacks can happen anywhere and no place is safe. Now the biggest challenge to tourism industry is to deal and manage the crisis in the event of terrorist attack.It is difficult to determine the impact of terrorism on tourism industry because twist of tourism and terrorism differ not across the countries but also over the time. Drakos K. and Kutan A. (2003) emphasizes the splendor of differentiating between different types of attacks, the locations of terrorist attacks (e.g. urban or hobnailed areas) and number of casualties. Aziz H. (1995) said terrorism could also be a reaction to irresponsible tourism development. The study of Enders W. and Sandler T. (1991) argue that it is found that the causality is unidirectional, that the terrorists affect the inflow of tourists but not reverse. The different studies, facts and figures show how tourism industry in concomitant country or region is affected by terrorist attacks. The deterrent impact of terrorism on tourism industry in particular country may benefit the tourism in option destinations.Financial impacts of terrorism on tourism industryThe literature on terrorism and tourism is scant. The two studies by Enders et al 1992 and Enders and Sandler 1991 provide observational evidence on the link between tourism sector and terrorism. Enders W. and Sandler T. (1991) used monthly data from 1970 to 1988 and employed VAR (Vector Autoregressive Analysis) to find negative impact of terrorism on tourism in Spain. Acco rding to Drakos K. Kutan A. (2003), Enders et al analyse a large have of European countries, between the periods 1974 to 1988 to find the impacts of terrorist attacks on tourism. They employ time series analysis and ARIMA technique with transfer functions and earn a forecasting model to analyse the impact on tourism in these countries. In these models they used quarterly terrorism data to measure the present value of loss in tourism revenue for selected sample of European countries. According to Enders calculation Italy, Greece and Austria lost $1.16 billion, $.77 and $4.5 billion respectively during 1974 to 1988. During this period all Europeans countries lost in tourism $16.15 billion due to terrorism. They desist that terrorism has significant impact on Europe tourism industry revenue and tourists find substitute destination in order to minimize the risk of experiencing terrorist attacks.The immediate effects of terrorist attacks are death and destruction but the subsequent effects are discourage investment, interrupt travel tourism patterns and destabilise economies. The economic effect of terrorism has been the main subject of number of studies. According to Enders W. Sandler T. (2002), the terrorist attacks have economically significant negative effect on the economic growth these attacks have less persistent and considerably little than the impacts of internal conflict or external war. Frey B. and Luechinger S. (2004), said that terrorists change tricks and tactics in reaction to the government polices, and it has direct effect on investment and economic growth. They also said that the investor decision to invest in particular country is based on economic risk, monetary returns and political risk. The foreign direct investment is one of the economic benefits of tourism, anything that effect on tourism needs to be minimised. Coshall J. (2005) claimed that Pan Am flight bombing in Lockerbie Scotland had minimal impacts on UK tourism and receipts f rom multinational tourists, while September 11 2001 had severe impacts on UK tourism and rest of the world.Different strategic management approaches of the tourism industry may have the same uninflected aspects to improve the performance of industry. According to context of world Tourism organization (2008) the international tourism is increasing day by day as in 2008, the trade happens of more than $944 billion and over 922 million international tourist arrivals at different destinations and 2009 number of tourist arrival to 880 million which is 4% decline compare to 2008. The most affected reign was Europe, curiously UK with a 6% decline.Terrorism can also destroy tourism industry by reducing tourist arrivals in UK. After September 11 2001, terrorist attacks in UK and continued threat of terrorist attacks also reduce the foreign direct investment significantly. According to Ritcher and Waugh (1986), terrorism and political violence can destroy the tourism industry supply and d emand because this industry is super sensitive to these extreme events. However, after September 11, 2001 the world has been threatened by terrorism, and acts of terrorism have increased in many countries including UK. The effects of terrorism on tourism decisions have been an area of research concern on demand. Drakos and Kutan (2003), Pizam A. (1999) and Krakover (2005) all agreed that the severity and frequency of terrorist attacks are negatively match with the tourism demand. The Pizam and Fleischer (2002) said that the frequency of terrorist attacks cause large decline in tourism industry demand. The intervention analysis by Coshall J. (2005) employs explore that the dynamics of the effects of terrorism incidents on those travelling or visiting UK and UK people going abroad.Influence of Media Following a Terrorist AttackModern terrorism is particularly onerous, because of characteristic of its time. The impact of terrorism on macroeconomic is crucial, customers purport thems elves in stress and some kind of continuous fear which emphatically effects the spending patterns. Media plays very important role with regards to terrorists activities around the world. Firstly, terrorist use media to send their massage to the audience, and general public relied on media for data in the times of crises. Now terrorist are using media to advance their causes of attacks. According to Sonmez and Graefe (1998), the escalation of terrorism after 70s has been linked to media, with instantaneous access to the spherical audience. Secondly, the media provide information to the public, what has happened, which normally enamour the public decisions about travel. In the event of terrorist attacks, Fischer H. (2005) discusses the importance of information, he said it is very difficult for emergency personnel to come and communicate the accurate information at the time of terrorist attacks. According to kill Katju (2004), media only report during the time of crises, it pro vides account to particular incident as long as its password and then move toward new news story when it happens. She said tourism industry has a great influence of media reporting and constant coverage of terrorist related incidents discourages the restoration of consumer confidence. Beirman D. (2003) said that the globalisation of media enhanced the ability to report terrorist events as they occurred, it also gives rise some problems and benefits to tourist authorities. In the word of Mansfeld and Pizam (2006), the media coverage and reporting on terrorist attacks have great impact on tourism industry, which transform the terrorism from frightening event into iconic event. Tourism industry needs to monitor media coverage of terrorist events, because this will care tourism industry to develop strategies, which will help it to restore the tourists and travellers confidence.Media have its ital role in endangering fear, among the society the irresponsible reporting generates scen es of ever present possibility of terrorist act. According to Crenshaw M. (1990) the new and fastest ways of communication allow people to know about happens in the other part of the world within minutes about any terrorist attack. On the other hand terrorist groups are adopting the latest techniques to communicate with each other and even sometime just for spreading fear with in the special(prenominal) community to achieve their targets. Czinkota et al (2004) cited that terrorist also using old tralatitious ways to communicate which are unable to penetrate. The latest ways of battery-acid system gives terrorist groups better way to move around. So we can say that media plays very important role for tourism industry in the time of terrorists incidents, as the media medium for terrorists to the public subsequently depend on the same media for more information on that incident.ConclusionThe discussion will cover some of the most basic concepts in the research of terrorism and its i mpacts on tourism. Tourism industry internationally and locally particularly affected by terrorism because when some things happen, it disrupts the activities of tourism and related industries. Every year more than trillion dollars are spent on combating terrorism. This along with billons dollars lost in property damage, loss of human resources and decrease in key industries potential profit like tourism, aviation, hotel and transportation industry. It is a plague on global economy and affects on everyone from entire countries to all the way down to individual. Terrorism in recent years has sparked, increase in fear and demand higher level of security. The cost of terrorism can be busted down into number of areas and come down to direct effects, response costs and negative effects on tourism industry.Terrorism effects tourism activates deeply. This threat compel almost every department of tourism industry, which cause decline in the profit of industry and on the other side the whol e economy has to bear the cost of every single act of terrorism. According to LCCI (2005) report, after 9 11 terrorist attacks, majority of tourism related industries fear high risk of terrorist attacks and they have contingency plan in place to deal with uncertainty. As globalization integrates multinational organizations and financial markets, events like terrorism which spurn economic uncertainty have increasingly international consequences. Terrorism causes unpredictable political and economic consequences, infuses the public with fear and prevents the free flow of capital, labour, and free market principles. Because of their disastrous impacts, occurrences of terrorism have ripe implications on the performance of tourism and related industries around the world. In past few years immediate responses and severe impacts are felt in tourism industry soon after terrorist attacks happened. These sustained reactions can be observed through macroeconomic impacts, government policy res ponses, tourists and investor confidence. As world move towards more liberal economies and democratic political structures, tourism industry must have the ability to adapt and respond to terrorist events. In order to do so, tourism industry and associated businesses, need a more staring(a) picture and understanding of the deleterious effects of terrorism.

Financial And Market Analysis Of Premium Economy Business Commerce Essay

Financial And Market Analysis Of Premium prudence Business Commerce EssayIn the respiratory tracts industry, in order to turn over success in the grocery place competition, superior market players stick go forth to cede a good understanding about the underlying subscribes in the market. Traditionally, airlines offer three major feather descriptores to the customers, namely parsimony, telephone circuit and first class flight and services. With the prosperous economic development and the increasing demand in air function, the idea of insurance gift rescue is introduced and it is now being widely accepted by the airline industry. Premium delivery, or whitethornbe called differently by different airline companies, broadly offers a wider space and more than than bountifulness service to passengers, and accordingly, requires a higher ticket price.The purpose of this account is to analyze the current performance outcomes and the market potential of bounteousness frugality blood. The first question pull out alone be answered with the comparison and compendium of tailfinr selected airline companies which have already launched bounty thrift work during operation. These five airline companies include Qantas, United Airways, British Airways, saturated Atlantic Airbus, and ANA. wherefore based on the performance outcome comparison, the second question leave be answered with a elevate market demands and input-output analysis.2.0 Premium parsimony duty in the five selected airline companiesPremium thriftiness, a niche market strategy widely introduced in keen-sighted haul market of business travel, is non monetary warningized. In United Airways, the idea of reward providence is called sparing Plus bit in British Airways, it is called World Traveler Plus. Meanwhile, superior parsimony business is being carried out differently in the five selected airline companies. Some may only fork up b are legroom with other service no more different from standard economy while other airline companies may emphasize a clear government note from traditional business by introducing priority come alonging, excellent on board service and entertainment, etc.2.1 Qantas bounty economy businessPremium economic system is uncommitted on all Qantas A380 aircraft and selected B747-400 aircraft with selected flights from Sydney to Los Angeles, capital of the United Kingdom, Singapore, Bangkok, Johannesburg, Hong Kong, Buenos Aires, San Francisco and New York, and from Melbourne to Los Angeles, London, Singapore and Hong Kong. In Qantas agiotage economy project, passengers are entitled to gets such(prenominal) as priority check-in, tautologic legroom for stretch out and relax, in the flesh(predicate) TV, laptop power for all pension economy back toothing room, and priority in disembarkation.Qantas has introduced three types of aircraft and twelve scheduled flights to provide premium economy business. Detailed sea t information is extracted and analyzed. Averagely, premium economy delivers a 2 extra inches of seat width, 7 extra inches of legroom. However, with an analysis into the seat number, it arse be seen that premium economy business is not so widely introduced in Qantas. Averagely, put for premium economy business just take up 9% of the good available seats in one flight. As to the ticket price for each class, for the most part, in Qantas, premium economy is generally 80% more expensive than standard economy. And the price for premium economy stays quite the alike for the all told month, thus pr planeting discount for advanced bookings (Qantas, n.d.).2.2 United Airways premium economy businessPremium economy is widely available on 15 types of aircrafts in the United Airways. The flight routes are selected between a variety of northwestern Ameri provide destinations and Hawaii. In United Airways, premium economy is called as economy plus, which is not a separate class of service but differs from standard economy with up to 3 to 5 inches of extra legroom. Generally, seats for economy plus are located nearer to the front of the aircraft, so that passengers in this section will be served first. Benefits such as priority check-in, ain TV, laptop powers, or priority in disembarkation are not entitled to economy plus passengers.Averagely, premium economy delivers almost the comparable inches of seat width, 4 extra inches of legroom. With a visit into the seat numbers, the radical average seats available on these aircrafts are 210, and averagely, seats for premium economy business take up 23.7% (50 seats) of the chalk up available seats. As to the ticket price for each class, generally, in United Airways, premium economy cost much the same with standard economy (United Airways, n.d.).2.3 British Airways premium economy businessPremium economy is called world travelers plus in British Airways, and it is available on 5 types of aircrafts and a variety of flight routes. In British Airways world travelers plus project, passengers are entitled to benefits such as priority check-in, extra legroom for stretch out and relax personal TV, laptop power, and priority in disembarkation.Averagely, premium economy delivers almost the same inches of seat width, 7 extra inches of legroom. With a look into the seat numbers, the correspond average seats available on these aircrafts are 268, and averagely, seats for premium economy business take up 11.5% (30 seats) of the total available seats. As to the ticket price for each class, generally, in British Airways, premium economy is generally 90% more expensive than standard economy (British Airways, n.d.).2.4 sodding(a) Atlantic premium economy businessPremium economy is available on 6 types of aircrafts and a variety of flight routes. In Virgin Atlantic premium economy project, passengers are entitled to benefits such as priority check-in, extra legroom for stretch out and relax personal TV, laptop powe r, and priority in disembarkation.Averagely, premium economy delivers a 4 extra inches of seat width, 7 extra inches of legroom. With a look into the seat numbers, the total average seats available on these aircrafts are 360, and averagely, seats for premium economy business take up 12.6% (45 seats) of the total available seats. As to the ticket price for each class, generally, in Virgin Atlantic, premium economy is generally 46% more expensive than standard economy (Virgin Atlantic, n.d.).2.5 ANA premium economy businessPremium economy is available on 5 types of aircrafts in ANA. The flight routes are selected from Nagoya to Taipei and Tianjin routes, Narita-Hong Kong route, Narita and North America as well as the NRT LHR route. In ANA, premium economy differs from standard economy by providing priority check-in, laptop powers, and priority in disembarkation.Averagely, premium economy delivers almost the same inches of seat width, 4 extra inches of legroom. With a look into the se at numbers, the total average seats available on these aircrafts are 257, and averagely, seats for premium economy business take up 12.3% (32 seats) of the total available seats. As to the ticket price for each class, generally, in ANA, premium economy cost much the same with standard economy (ANA, n.d.).2.6 similitude of the premium economy businessWith the introduction about the five selected airline companies premium economy business, it is noted that all the five companies have provided passengers with up to 7 inches of extra legroom. Additionally, except for United Airways, Qantas, British Airways, Virgin Atlantic, and ANA have provided extra benefits for check-in/out and on board service. Such benefits can save much fourth dimension spent on travel and could leave passengers with a good service impression. However, such benefits are provided with the add in operation be.Moreover, the adoption levels of premium economy differentiated with each other to a great extent. Among the five airline companies, Qantas has the lowest percentage of premium economy seats to the total available seats at approximately 9% while for United Airways, the percentage of premium economy seats to the total available seats is at the highest level around 23.7%. The variegation in intersection point portfolio may generate the problem of cutting be down.3.0 Financial performance of the five selected airline companiesAs no circumstantial r yetue information on the premium economy business could be available from the companies relaxd financial reports, comparison of the financial performance for the five airline companies would be carried out with theoretical analysis.For the airline industry, major airlines have long been troubled by the matter of tremendous firm costs such as the repair and maintenance of the aircraft, overhead costs and the increasing costs of fuels. In order to cover such costs, airline companies need a great number of passengers to meet the break-even point. In calculating the break even points for each airline service product, the companies may generally follow the formulas at a lower place (Horngren, Sundem Stratton, 2002)Break even point (for output) = fixed cost / contribution per building blockContribution (p.u) = selling price (p.u.) variable cost (p.u)Break even point (for sales) = fixed cost / contribution (pu) - selling price (pu)During operation, the companies will try to lower the break even points so that they can maximise their profits. In order to achieve this, companies can get down on the following aspects control the fixed cost, increase the output units ( lactating passengers), or increase the selling price. As to fixed cost control, it mainly involves improvement on internal control and management while the pricing strategy will be mainly affected by the passenger market.4.0 Product favorableness analysisWhen making decisions on overbold product launches, the companies should assess the profitability of current product portfolio, and the potential profits which may be generated with a new product portfolio.Due to the fact that premium economy generally provides passengers with up to 7 inches of extra legroom and above 2 inches of extra seat width, the introduction of premium economy will inevitably lower the fixed cost amortization. However, if the implementation could generate more loaded passengers, thus the sort out in fixed cost amortization could be subsidized.The impact of decrease fix cost amortization could be measured by assume that if the same level of product profits be generated, how many loaded passengers are required. With the figures calculated, a market analysis should be carried out to scrape up out whether such target could be achieved.5.0 Market acceptance and market potentialEvery individual in the global world could be potential customer to the player. However, due to limitations resulting from factors like geography, operation scales, cost and benefit pr incipal, etc, the player has to narrow down onto series of segment markets and figure out its target customers, and then focus its marketing efforts and its merchandise on the selected areas (Kurtz, 2010). knowledge about target consumers backgrounds and their complex buying decision making execute is an indispensable part of accurate market identification and positioning occupation (Nicosia, 1966).The idea of premium economy is firstly introduced to address the increasing demand from business travel. Unlike traditional market strategy which emphasize severely on price and cost, strategies for premium economy pays more attention to the product and service quality, as in many cases price is not the old issue for the business traveler.With the help from advanced information technologies such as visual conferencing, instant messaging system, content management system, etc, business can be done with participants locating all around the world. However, when coming to circle under w hich face-to-face interaction is inevitable to the success of the business, air travel, for its thingumajig and metre saving characteristics, will come as the first survival of the fittest for business travelers.To such targeted business travelers, what they want most from the flight would generally be the comforts and time saving. Traditionally, the time spent on wait for check-in/out procedures would almost be more than two hours, which may mean quite a huge time cost to the business. Moreover, exhaust by the uncomfortable sitting environment, passengers may take certain time to fresh up their spirit and energy. This may generally have nix impact on their performance.With the introduction of premium economy business, travelers are provided with more space in which they can stretch out regularly and release the pressure so that they will not feel tired subsequently the journey. Moreover, with the priority in check-in and disembarkation, business travelers could save more tim e for other important issues.With the product being accepted in the market, it should likewise be figured out the potential market volume. According to the gracious Aviation Authority (CAA), in 1999, approximately 30 percent of passengers from London to New York were business travelers (1.14 million passengers) (Sky Trails Airline, Ltd, n.d.). If such percentage could be utilize to other heated commercial flights, the total market potential could then be analyzed and the product profitability could be worked out accordingly.6.0 closingWith the increasing demand of long haul travel and the increased tubercular power, the introduction of premium economy will become a habitual and inevitable trend in the airline industry. In order to impart a proper investment decision on product introduction, the airline companies should first work out the break even point of the new product, and then analyze whether such profit could be realized in the current market. Moreover, in introducing t he product, the companies should also consider the characteristics and major demands of the passengers and then further tailor the products to their specific needs.List of referencesANA, n.d., Premium Economy, viewed 17 August 2010, http//www.ana.co.jp/wws/uk/e/travelservice/reservations/special/py/index.htmlBritish Airways, n.d., World Traveler Plus, viewed 17 August 2010, http//www.britishairways.com/travel/world-traveller-plus/public/en_gbHorngren, C, Sundem, G Stratton, W 2002, Introduction to Management Accounting, Prentice Hall, London.Kurtz, DL 2010, Contemporary Marketing, 13nd edn, Thomson South-Western, Mason, Ohio.Nicosia, F 1966, Consumer Decision Processes, Prentice Hall, Englewood Cliffs.Quantas, n.d., International Premium Economy, viewed 17 August 2010, http//www.qantas.com.au/travel/airlines/international-premium-economy-class/global/enSky Trails Airline, Ltd n.d., Business Plan, viewed 17 August 2010, http//www.referenceforbusiness.com/business-plans/Business-Plan s-Volume-09/Airline-Company.htmlUnited Airways, n.d., Economy Plus, viewed 17 August 2010, http//www.united.com/page/ obligate/0,6722,1314,00.htmlVirgin Atlantic, n.d., Premium Economy, viewed 17 August 2010, http//www.virgin-atlantic.com/en/cn/whatsonboard/premiumeconomy/index.jsp

Urinalysis of Four Urine Samples

Urinalysis of Four body of water SamplesUrinalysis Practical sceneAs you have learned, the urinary system performs many vital functions in the body includingRegulating agate line volume and pressure by regulating water excretion,Regulating plasma ion/solute concentrations by adjusting piss composition,Assisting blood pH stabilisation,Removing nitrogenous waste,Conserving water and important nutrients andAssisting the liver in detoxifying poisons.Therefore, analysing a taste of water supply from a person can provide important selective information on the health of that person. Urinalysis can reveal unhealthinesss such as diabetes mellitus, urinary packet infections and renal (kidney) infections such as glomeronephritis and kidney stones (renal calculi).A medical examination professional ovalbuminthorn perform a urinalysis for several reasonsAs a general health check-up,Diagnosing metabolic or general diseases that affect renal function (heart failure will lead to decreased blood flow to the kidneys, pre-eclampsia during pregnancy will lead to change magnitude protein in the pissing),diagnosing of endocrine disorders e.g. infertility (low levels of FSH and/or LH),Diagnosis of urinary system disease,Monitoring of glucose levels in patient roles with diabetes,Testing for pregnancy (hCG levels secreted by the embryo),Screening for drug practise.Urinalysis is a technique involving physical, chemical and microscopical analyses of a stress of urine.Physical parameters Normal urine is a wanton yellow colorise due to the posture of uribilin. Abnormal urine may be dark orange, red or brown and cloudy in appearance. This can be due to the presence of red and/or white blood cells or pigments and may suggest a urinary tract or renal infection or disease, liver or pertness bladder disease. Normal urine has a specific gravity of amid 1.002 1.028 (this is a measure of the number of particles/solutes in the urine, its concentration). A urine try on that has an elevated specific gravity can indicate dehydration, diarrhea/vomiting, glucosuria, unconnected ADH secretion. A diminished specific gravity may indicate such diseases as renal failure or pyelonephritis.Chemical parameters The chemical analysis of urine is routinely performed using an inexpensive and relatively precise dipstick test (Uristix from Bayer or other brands). The test uses a reagent-coated moldable stick that is placed or dipped into the urine sample. The reagent areas change colour according to the presence of glucose and/or protein.(a)Figure 1. Colour chart (a) for use of glucose and/or protein. The glucose test on the dipstick is based on a mental image sequential enzyme defendion. One enzyme, glucose oxidase, catalyses the formation of gluconic dit and hydrogen hydrogen peroxide from the oxidisation of glucose (if present in the urine). A second enzyme, peroxidase, catalyses the reaction of hydrogen peroxide with a potassium iodide chromogen to oxidise the chromogen to colours ranging from dark-green to brown. Normal urine has less than 0.1% glucose concentration.The protein test on the dipstick is based on the protein-error-of-indicators principle. At a constant pH, the development of any green colour is due to the presence of protein. Colours range from yellow for negative through yellow-green and green to green-blue for positive reactions. Normal urine has a protein concentration of less than atomic number 6 g/ml. Although the dipstick test is semi-quantitative, significantly more accurate levels of glucose and protein can be escortd by other means. In this practical you will use a BCA Assay (discussed later) to quantify the amount of protein present in a sample of urine.Urinalysis may also include assaying for levels of ketones (an indicator of diabetic ketosis, fasting or starvation), blood cells (indicating infection or kidney stones), bilirubin (liver or gall bladder disease), drugs and many other substances.Microscopic parameters The urine sample can also be analysed by a microscope, often afterwards staining to reveal any pathogens such as bacteria, urine crystals, cells and/or mucous. The presence of any of these may indicate infection or disease and further medical investigation will provide a unadulterated diagnosis.AimThe aim of this practical is to perform glucose and protein urinalysis techniques on five-spot samples of urine provided by five patients and use this information to provide an sign diagnosis for each patient. serving One Using Dipsticks To give up A Qualitative Measure of Protein And/Or Glucose.Materials5 samples of urine labelled A E (these will be required for Parts One and Two),5 Uristix dipsticks.MethodPerform a basic physical analysis of the urine samples noting the colour and cloudiness of each sample body of water AUrine BUrine CUrine DUrine EColourCloudinessImmerse a dipstick into each of the samples, wait 60 seconds and record your results using the colour chart in Figure 1 to determine if the sample contains glucose and/or protein or neither substanceUrine AUrine BUrine CUrine DUrine EGlucoseProteinKetones prejudiciousNegativeNegativeNegative strongly positiveBloodNegativeNegativeTraceNegativeNegativePart Two Using A Commercial BCA Assay To Provide A Quantitative Measure of Protein.BackgroundThe BCA Protein Assay exploits the chemical lessening of Cu2+ to Cu1+ by protein in an alkaline medium with the selective colorimetric undercover work of the cuprous cation (Cu1+) by bicinchoninic acid (BCA). The first mensuration is the chelation of copper with protein in an alkaline environment to form a blue coloured complex. In this reaction, known as the biuret reaction, peptides containing three or more amino acid residues form a coloured chelate complex with cupric ions in an alkaline environment containing sodium potassium tartrate. Single amino acids and dipeptides do not give the biuret reaction, but tripeptides and boastfulr polypeptides or proteins will react to produce the light blue to violet complex that absorbs light at 540 nm.In the second step of the colour development reaction, BCA, a extremely sensitive and selective colorimetric detection reagent reacts with the Cu1+ that was formed in step 1. The purple-coloured reaction product is formed by the chelation of two molecules of BCA with one Cu1+. The BCA/Cu complex is water-soluble and exhibits a strong linear absorbance at 562 nm with increasing protein concentrations.The rate of BCA colour formation is dependent on the incubation temperature, the types of protein present in the sample and the relative amounts of reactive amino acids contained in the proteins.Figure 2.
