File transfer protocols Essay Example for Free

File transfer protocols Essay File transfer is the process of transmitting complete files from one computer to another. To achieve a successful transfer, both sending and receiving devices must establish the protocol (set of rules) by which they will communicate. Various protocols are commonly recognised but they vary in their performance and suitability for particular tasks. Some examples are described below. FTP File Transfer Protocol (FTP) allows large amounts of information to be transferred between computers very conveniently. FTP originated with the UNIX operating system and was to transfer files of all types between remote computer systems. A popular application of is for the uploading and downloading of Web site pages. ASCII This is only appropriate for text files, which contain no control characters. Thus it cannot be used to transfer files produced with a word processor, spreadsheet or graphics package. Neither can it transfer command (COM) or executable (EXE) files, or files in compressed (ZIP, for ex) form. Apart from this, the protocol is not good at controlling errors. Xmodem A file-transfer protocol used for asynchronous communications. It is commonly used in communications packages. The Xmodem protocol transfers data in blocks of 128 bytes, giving each transmitted frame a sequential block number; this number is used to identify the location of errors. A checksum (see Block Check Characters) is attached to each block to check transmission errors. Its ability to find and correct errors makes it suitable for the transfer of files, which must retain their integrity, such as program files. Zmodem Is one of the most advanced protocols, being much faster than Xmodem. Its error correction controls are absolutely reliable. CCITT V42bis. This protocol includes a data compression (through encoding, data is reduced in volume) technique and error detection and correction. Both the sending and receiving modem must possess the error correction facility. Implementation Top Down implementation is one way to achieve implementation of software. This involves coding, testing and debugging each module in turn starting with the top level and working down. This means that each new module fits naturally into the module hierarchy. Starting with the control module i. e. Songs; we code, test, debug and retest it etc. This involves calling Set_Up, Process_Votes and Menu, even though these have not yet been coded. Therefore, we create test stubs to ensure that we can test that the Songs module achieves its function. A Test Stub can simply consist of a statement which will display a message showing that the module has been called correctly, or it may consist of a set of statements which simulate the operation of the module in order to return results to the calling module which is under test. At this stage, the program would look like this Program Songs(Input, Output); Plan should be constructed which indicates an incremental development where each module is to be tested in turn, with appropriate test stubs. For each test, expected results should be noted. A Test Log indicates the results of each test run, whether the test is successful or not. If a test is successful and an error has been discovered then the code should be redesigned, amending pseudocode, recoded and retested. Total_Votes In 3. Narrative Description No Module Description 0 Songs Calls Set_up to set up the table, Process_Votes to read votes from the keyboard and Menu to offer options. 1 Set_Up Calls, in turn, Initialise and Load. 2 Process_Votes Reads in votes from the keyboard and increment the appropriate total. 3 Menu Displays menu, accept choice, and call appropriate modules Display or Report 1. 1 Initialise Initialises all entries of the table. 1. 2 Load Reads in the song details from the file and store in a table. 3. 1 Display Displays the number of votes for an input song. 3. 2 Report. Displays the percentage votes for each song. Subprogram. Stepwise Refinement is a process which takes an initial solution to a problem and refines each step until the algorithm is detailed enough for implementation in a suitable high level language. Level 0 Level 1 Level 2   Since programs can become very large and consequently can involve a number of programmers in the development process, it is useful to have a way of splitting up a program into components each of which can be handled separately. This uses a facility called a subprogram. The process of developing a solution as a collection of interconnected subprograms is called Modular Design. Each module has a single complete function and is implemented using the particular subprogram facilities of suitable high level languages. Pseudocode Each programmer can be allocated a separate module / group of modules to work on in isolation. Each module may call lower level modules. A module may be called from more than one other nodule. Programmer A Programmer B Programmer C   A subprogram is a way of grouping together statements which havea common purpose i. e.all statements help to produce a singleobjective. They allow a natural way of dividing an algorithm intoparts where each individual part can be handled separately andcarries out a single task for the problem. This is a natural extension of the philosophy of stepwise refinement where subprograms may be executed in sequence, be part of a selection or be iterated. A subprogram can be thought of as a small program which can carry out any of the functions of a program. A subprogram is called when it is needed, executed and then the processor returns control to the place where the subprogram was called from. Although subprograms can be developed in isolation, by separate programmers, they have to communicate with other subprograms in the system, particularly, with regard to the data which is shared between a subprogram and its caller. Subprograms communicate with the calling program through a well-defined interface which specifies the data being shared between the calling program and the subprogram. The interface allows the processor to suspend the calling program, transfer control to the subprogram and pass any data specified down to the subprogram. Once the subprogram finishes executing, then the interface communicates any required data changes back to the calling program and returns control to the main program at the line immediately after the subprogram call. A subprogram may be called any number of times within a program. The subprogram heading specifies the subprogram name, the type of each piece of data which is expected and the nature of each piece of data, i. e. whether it is simply to be passed down in order to aid the function of the subprogram or whether it. is a value which is being changed or calculated as part of the function of the subprogram. A piece of data which is being passed to/from a subprogram is called a parameter. A parameter has an associated data type e. g. integer. A parameter can be specified as either value (reference) or variable depending on whether the subprogram is allowed to change the parameter value permanently. This allows the program to protect certain parameter values against accidental change. e. g. Subprogram Add_Nos(Numl, Num2 : Integer; Var Result : Integer) Here Num1 Num2 are value parameters therefore the subprogram will expect to receive input values for each of these parameters every time the subprogram is called. These values can be supplied either as variable values or constants. e. g. Call Add_Nos Using Numi, Num2, Result Call Add_Nos Using 5, 6, Result Result is a variable parameter and therefore the subprogram will change/calculate a value which is to be returned to the calling program. Thus the subprogram will expect to receive the name of a variable of the required type where it is to store the returning value. The subprogram call must contain a data value (of a suitable type) for each corresponding parameter in the subprogram heading. When a subprogram is called the data values in the subprogram call (actual parameters) are passed down to the corresponding data values in the subprogram heading (formal parameters). Since a subprogram can be used more than once within a system then it is necessary to allow different names to be used for formal and actual parameters. e. g. Call Add Nos Using Nol, No2, Result Exercise Design an algorithm which will input 2 integer values, display a menu, read a choice and call an appropriate subprogram to add, subtract, divide, multiply these numbers returning the result of the calculation. The Systems Development Cycle System Testing and Implementation Implementation is the stage where the system design is converted to a working system. This is arguably the most important stage of systems development, since a well designed system which is poorly implemented may. fail, whereas a badly designed system which is well implemented may survive. The key to success is in planning for the implementation early in the design process, the main issues to be considered being :- ? site preparation ? hardware/software procurement ? system testing ? user education and training ? changeover ? Outcome 6 of the Systems Development 2 Unit includes system testing, user education and training and changeover, and these topics are outlined in the following sections. System Testing System testing ensures that the system works accurately and efficiently before it is put into live operation. All clerical and computer procedures are tested. Programs are tested individually and then in groups to verify program linkages. Hardware and communications links are also tested. The final stages of testing are the system trials involving user staff, this also being part of user training. Test data for program testing should follow the guidelines of the Software Engineering Unit. System trials should be carried out in an operational environment, using test data from earlier time periods, or even parallel runs with the old system using live data. The types of tests which should be considered for a system are as follows Inputs- form design (ease of use) data transmission input validation and correction Files- empty files addition/deletion/update access controls/security Outputs- output documents/screens recipient understanding ComputerProcedures- program linkages operating procedures recovery and security timings Clerical Procedures- effects on other systems user understanding error correction timings User Education and Training The success of a new system is very much dependent on the attitudes of the people who use it. Education aims to convince users of the benefits of the system to themselves, their department and the company. Management policy regarding re-deployment ,redundancy etc should be clearly stated. while casualties may result from the introduction of new systems, there are also many positive aspects such as ? reducing very boring clerical activities? upgrading of skills ? ? improving job satisfaction ? d? Education, therefore, complements and is a pre-requisite to training. e? Training enables users to understand their role in the new system, and prepares them for their own specific tasks. The users and people affected by the new system must be trained, and arrangements for release from normal duties must be made. Many different methods of training are available including f? formal lectures a? ? discussions/seminars ? computer-assisted training (tutorial packages,help facilities etc) ? user manuals/quick reference guides ? Usually a combination of methods will be chosen with an emphasis on hands on experience. Timing and pacing of training is also important, too early and users may forget aspects or become disinterested, too late and users will become flustered. Training does not cease with implementation, but must meet needs of new staff and system changes. changeover Implementation may involve change from a manual system to a computer system or from one computer system to an other. In both cases the system data and procedures require to be changed. A major task prior to changeover is file conversion. The data in existing clerical or computer files must be converted to the new system files, and this can be a massive task involving the preparation of thousands of records using data from a number of different sources. It is also essential that the new system data is accurate or system credibility will suffer. Changeover is the period from the start of live running to the time the DP department withdraws system support, other than for maintenance. ? Methods of changeover depend on the particular circumstances of a system development project, and fall into the following categoriesdirect changeover ? parallel running? pilot running ? Direct changeover is the complete replacement of the old system by the new in one move. This may be appropriate when system testing has been exhaustive and users have complete confidence in the new system. Also if the system is totally new and there is no comparable old system, or if there is no staff available to operate a parallel run. Parallel running is the method of processing current data using the old and new systems at the same time, then cross-checking results. It may be seen as an extension of testing, and generates confidence among users, however it places a strain on resources. Pilot running may be used in two ways, either in retrospective running of data from previous time periods, after results have been obtained from the old system, or as a staged changeover where a complete logical section of records is chosen and committed to the new system without parallel operation in the old system. when this section is operating satisfactorily the remaining records are transferred. The end of the changeover is signified by user acceptance of the new system. System performance must meet acceptance criteria previously established. Acceptance criteria would relate to factors such as response times, degree of reliability and tolerable error rate. Test Narrative An incremental development approach will be taken. This will involve each module being designed, coded and tested in turn before moving onto the next. This Top Down approach will allow newly written modules to fit naturally into the module hierarchy. Test stubs will be used to simulate the calling of modules which have not yet been coded. Menu Tests would be continued until all tests completed amendments logged and retests completed satisfactorily . Interviewing Interviewing is better than questionnaires for gathering certain information because you could see the interviewee facial expressions. Also one other advantage is that in an interview you can hear the response of the interviewee has to say. One disadvantage about the interviewing is that it takes long of time. But couple of things you would gain from the interview is that you would be gaining the trust in the interviewee, you would be making the interviewee feel important and it shows that you are interested. They will be able to give to the interviewer information that will be of value for the new system. If the interviewee says that the current system is unsatisfactory then you will need to look at the weak point of the current system and making sure that you dont make the new system have similar problem as the current system. Interviewing is factual and you would get the answers to know questions right away. Some other problems in a interview is that there isnt enough detail to know whats happening in the job and needs to meet the interviewee to observe the body language. Interview is long but an questionnaire is quicker but it has less information. Questionnaire Questionnaires are useful when you are gathering a small amount of information from a large number of people. But if you are getting a lot of information from people then it will take you a lot of time to process the whole information which will take a lot of time. A questionnaire is quick if it is a small amount of information, it is simple but a questionnaire has a slow response. A questionnaire is quicker than an interview. Questionnaire is one of the best resources to get information from. Like documents they do have information but documents it may not be regularly updated. Examination of documents is factual and has a lot of information but depending on what you are looking for. In a questionnaires you wouldnt get as much information as examination as documents. Some problems in a questionnaire is the person may not be as honest as the person would be in a interview, an questionnaire is too long and boring. Questionnaire is easy to analyze. Study of forms and documents. Procedures manual is an already made source of information so all you got to do is read the information. Examination of documents is the quicker than interviewing and Questionnaires. Records are all factual like all the rest but one of the main things may be bad about is that the information may not be as accurate as a Questionnaire and Interviewing .

Tesco Business Analysis

Tesco Business Analysis Introduction: Tesco Plc is a British based company, and is the largest food retailer in the UK. It is one of the largest British sellers and holds third rank in retail industry after USA based company Wal-Mart and France based company Carrefour. It sells around 4000 food products (Euromonitor, 2010). Tesco started with the business in grocery retailing, but now it also sell stationary, health and beauty, utensils, clothing, home entertainment, electrical goods, kitchen utensils and seasonal goods like barbeques and garden furniture in the summer. Annual profits of Tesco in year 2005 was announced as  £2 billion and in 2006 it announced that it was going to open foreign stores very soon. Tesco operates in 13 countries with 3275 stores of which 2115 operates in UK; its largest geographical market (Euromonitor, 2010). It operates through different store formats which include Extra, Express, metro, hypermarket and superstore. Tesco has its own products ranging from value, normal and finest for diff erent income group of consumers. Tesco was founded by jack Cohen 1919. It gets its name from the combination of the founder of Tesco, Sir Jack Cohen and a partner in a firm of tea suppliers who Cohen worked with, T.E. Stockwell (Marketing (00253650)). One of the biggest investment of Tesco was in the 1980s, when Tesco invested  £145m for a superstore development program and invested  £500m in building 30 new stores (BSC). The company floated on the stock exchange in December 1947 with an initial share price of 25p (LSE). Beyond the food, Tesco also sells non-food products including electrical goods, home entertainment, stationary, clothing, beauty and health, kitchen stuff, soft furnishing and season products as barbecues and garden furniture in the summer. The company has become as one of the UK’s biggest independent petrol retailer (Datamonitor, 2010). Moreover, the group provides financial services (Tesco Personal Finance) which was set in joint-venture with Royal Bank of Scotland and became one of the successful projects of the group. Tesco’s Core Purpose, as stated on their website is â€Å"to create value for customers and to earn their lifetime loyalty†. Competition in Retail Market: The market in which Tesco operates is a highly competitive field, where Tesco holds a disproportionate amount of power. Tesco has three major competitors – Sainsbury, Asda and Morrison. These giants of retail have many chains and a collective mass that can influence the food market as a whole. The figures below shows that Tesco holds over a third of the UK market share, and even double the amount of Asda’s market share which is the second largest supermarket chain. Following is a breakdown of the market share data published by TNS for the 12 weeks to June 15, 2008 (Reuters News, 2008): However, the recent financial crisis put Tesco under the pressure when its customers by seeking reduce its expenses switched to cheaper alternative supermarkets as Lidl, Asda and Aldi. According to the latest TNS data Tesco, Sainsburys and Waitrose are losing share of the UK grocery market. Tesco’s sales increased by 5.5%, Sainsburys sales went up by 5.6% , sales of Waitrose just climbed by 1.6% while such hard discount retailers as Aldi saw its sales jump 22.1% over the 12-week period and Lidl posted sales growth of 9.8% (Just Food, 2008). . To maintain its market share, the company has tackled the problem by releasing 400 low -cost new ranges of food and products on their shelves. Today Tesco has 273028 employees and it is the largest British retailer with profit exceeding  £2bn, including global sales and domestic market share. In 2008, Tesco became the 4th largest retailer in the world. STEEPLE+E Analysis: There are rules and regulations which are set by the government so that there should be no monopolies and healthy competition in the market. Consumer law emphasis on protecting the consumer rights and make sure that the entrepreneurs have the chance to compete in the market. According to the EU law there is assumption that the companies with large market share are dominant, the problem with this is there may be compromise on the quality of the product and costumer may end up paying higher prices for the products. As Tesco has a large market share, it has not been assessed till now but Tesco should bear this in mind. Planning consent is highly regulated in UK therefore Tesco should take care of this regulation as expansion is one of the strategies which Tesco follows. Therefore, before setting up a new store Tesco should check all the planning permissions and look if there are any resistances on law grounds or local people’s opposition. In the recent downturn of economy many r etailers were affected badly but Tesco was fortunate as it was not affected that much like others because it makes product for all, it offers a wide range of products from value to finest so it helped people to switch to value products in recession. Increase in tax or stock market fluctuation or change in currency can also affect Tesco. In the sociological aspect Tesco has focused on launching the products like meal for one and microwavable products to make life easy for the people migrate from the other parts of the world and are young professional. Tesco has made use of the technology fully by launching the site tesco.com which makes the life of people easy by order the products from their home and it also gives Tesco a competitive advantage. Tesco has supported the carbon reduction process and have raised 100 million pounds for sustainable technology fund; Tesco also encourages its customers to help in reducing the carbon emission by using the same plastic bag many times, another challenge for Tesco may the reducing the use of fossil fuel which is used in its transportation. SWOT Analysis: It has strong brand image and market leadership. Tesco is the largest retail group in the UK, which has about 30% of the UK grocery market as of June 2008, at the same time; it has successful business which operates in 14 worldwide markets beyond the UK. The company built up a good reputation enables the group to launch new products and services, and makes easier entering in new markets. One of the best examples was entering into financial services market with Tesco Personal Finance project (Datamonitor, 2010). The group has a stronger market presence in South Korea as compared its main rivals as Wal-Mart and Carrefour. These two Tesco’s competitors sold all of its stores and divest its operation in 2006 in South Korean, due to inability to meet consumer’s demand (Datamonitor, 2010). This success encourages the company on making investments in order to sustain market leadership and generate more profit. As the result, company is spending 958million pounds on expanding and acquisition new stores in South Korea (FT, 2008a). ‘Tesco.com is the largest online grocery shopping service in the world; it is the fourth biggest online retailer in the UK, behind Amazon, Dell and Argos.’ (Datamonitor, 2010). In 2008 Tesco.com sales continue to growth constantly. Sales from Tesco.com grew by 20% in the first half of 2008, reaching 902million pounds (Tesco, 2010). Taking into consideration the online sales are forecasted to increase from 10.9 billion pounds in 2006 to 28 billion pounds in 2011 (Datamonitor, 2010), Tesco can get considerable benefits from strong foothold in online services. Notwithstanding on company’s big plans to extent or open new stores in the UK, it becomes difficult to realize as not all expand projects satisfy local community’s requirements and finally have been frozen in waiting for government’s decision. There are some negative event influences, patent infringement claims, for example, in 2007, â€Å"Franks International filed suit against the company in US District Court for the Eastern District of Texas, Marsheall Division alleging that Tesco’s CDS infringes two patents held by Franks† (Datamonitor, 2010). Tesco do not have the small convenience store to service customer who the small areas, while the Sainsbury has the small store in the local small town , it is convenience for customer, they do not want by a lot of things, maybe just some daily consumable. There are lots of opportunities in other international markets for Tesco; the Euro zone retailing sales has shown a growth of 33% as of August 2008 to compare as of August 2007, which comprised 4,732mllion pounds and 3,558million pounds respectively. While sales in Asia increased by 11% at the same period from 2, 862million pounds of as August 2007 to 3,151million pounds of August 2008, despite of a small loss in the first half as a result of establishing operations and supply hubs in China (Tesco, 2010). About 80% of group’s capital is being invested in international growth (FT, 2008b). For instance, investment in markets of rapidly growing economy such as India with planned investment around $114 m to set up the business, in China where Tesco has spent 180million pounds in 2007 to increase its stake in its local partner (FT, 2008b). This provides a good opportunity to cover consumer’s demand of these markets which can add value to the Group’s assets and signif icantly contribute to maintain its strong international performance. Notwithstanding on only 9 month of running business in the US, the Group has obtained sales result ($11 per square per foot per week) which is also encouraging. Successful experience of operation on international markets enables the company’s to embody its plans of further overseas expands. Tesco has opportunities in non-food and services markets also, total UK non-food sales increased to 4.1billion pounds and 1.7billion pounds from international market as of August 2008, which in total led to 7.3% sales grew (Tesco, 2010). However, Tesco has poor results in this market segment, while with skills in sourcing and supply chain management the company has opportunity to improve its position. Tesco Personal Finance made profit 71million pounds, where Tesco’s share was 35.5million pounds, up 34% compared to 2007 (Tesco, 2010). The Company completed the acquisition of 50% of TPF from the Royal Bank of Scotland by the end of 2008 (Tesco, 2010). Threat to Tesco is high competition as the result of financial crisis and consumer’s budget tightness such discount competitor as Alsi and Lidlrs are eaten away Tesco’s sales by offering high quality goods for the lowest price. The group faced risk of losing its customers who switched to the other retails in order to reduce its living costs and had to revise its strategy in order to remain its customers. McKenzie’s 7s Analysis: McKenzie 7 S’ includes shared values, Strategy, Structure, System, Staff, Style, Skill. Accordingly Tesco applied the 7 S’ of McKenzie as well to increase its market share and profits which are described as follows: Shared Value: Shared Value of the company states the objectives of the company and it’s believes. Tesco believes in increasing its sophisticated management techniques from simple manufacturing companies to the value of higher standards and marched northward on their value chain. Strategy: Strategy describes about the methods adopted by the company to achieve its goals. Tesco applied various strategies usually using Balanced Scoreboard (BSC) method. Structure: It depends on the companies infra structure like top to down management. Tesco CEO thinks that they don’t need of one leader, they a whole group of employees from top to down to work on strategies. System: System is based on how to finish a work like how important is the wok and how smartly it has to been done. Tesco used a steering wheel to achieve its pre determined strategies smartly simply used to help the employees in future. Staff: Staff states about the number of staff in the organization. All over the world Tesco recruited more than 400,000 employees. Style: It the style of the organization in which it works to achieve its objectives. Tesco used steering wheel to achieve its objectives. It has 90 degree arcs, in which four main areas are considered which are, financial, customers, operations and employee performance. Skill: It describes the capabilities of the organization or the employees to a particular task. Tesco provides full knowledge to its employees to work effectively and efficiently within the organization. It provides skills to the employees to work according to the standards of Tesco (Kaplan R. and Norton D., 2008). Micro Environment analysis and Marketing Strategy: Position of offering the best value for the most competitive prices contributed to be Tesco number one retail in the UK. Smart Supply Chain Management and Development strategy, constantly research, seeking in order to meet customers’ needs, introducing new innovation, product quality and price, offering huge product range, store facilities and services, working closely with suppliers, developing and motivating its staff, participating in the formulation of national food industry and environment protection makes possible to keep strong competitive position within market even through time. Terry Leahy, CEO of Tesco plc states â€Å"there are many opportunities for business like Tesco as long as you stay close to customer and adapt to the changing circumstance† (ICSC Research Review, 2008). The group provides online services through its subsidiary Tesco.com, broadband internet connection (Tesco Broadband) and telecommunications services (Tesco Mobile and Home Phone). â€Å"Tesco.com is the largest online grocery shopping service in the world; it is the fourth biggest online retailer in the UK, behind Amazon, Dell and Argos. Tesco.com serves 850,000 regular customers in the UK and gets more than 250,000 orders every week† (Datamonitor, 2010). Significant advantages of buying online, such as comparatively low price, large product range and the ability to shop around the clock — enable retailers to draw shoppers’ interest (Gladding, 2005). â€Å"Tesco, the United Kingdoms biggest grocer, has attracted considerable attention because of its ambitious overseas strategy and its successful on-line home delivery service† (Child, 2002). â€Å"Since establishing an MVNO with 02 in 2003, Tesco has built up 1.5m mobile subscribers and 250,000 of these v isits the mobile portal every month† (New Media Age, 2008). Hence, Tesco makes possible to carry into effect purchasing by using mobile phones and brings new life in m-commerce shopping (New Media Age, 2008). According to company’s recent press release information Tesco.com sales up 20.5%, profit up 21.4%, including Tesco Direct (Tesco, 2010). Datamonitor (2010) in its â€Å"Tesco, PLC SWOT Analysis† states that â€Å"With a strong foothold in online services, Tesco is well placed to benefit from growing online spending. A strong online presence enables the group to serve new customer segments, avoid investments in physical infrastructure and earn better margins†. The company has an impressive brand image, which is associated with high quality goods and services, huge range of assortments and at the time the best prices. Credible brand name enables the company to launch more new products and new market lines; to go through new markets much easier and quickly, and become successful in this field as well, as it was its entry into the Personal Finance market (Datamonitor, 2010). Through the diversification process, Tesco has increased the range of its operation by entering to new markets of distribution and service supply, such as petrol distribution, banking and insurance, real estate and communications. Such changes and strategy improvements have further reinforced company’s market power above its main competitors. Since the mid-90s, Tesco has been investing in overseas markets, by looking for new opportunities to expand and opening new ways of generating long term growth of shareholders value. Today the Group operates in 12 markets outside the UK, in Europe, Asia and North America. The half of the retail shops are represented beyond the UK (Tesco.com). As a part of international expansion, now Tesco is planning to open wholesale grocery store in India by investing up to $114 million over two years. â€Å"It complements our entries into China and the United States, giving us access to another important economy in the world† commented this decision the company’s chief executed (World Trade, 2008). At the same time, Tesco announced that it has set up a South China headquarters office in Guangzhou in order to maintain its’ presence in this country, where the company already has 47 stores and has been running the business over three years long (World Trade, 2008). As a part of supporting its global expansion programme, the company plans to centralise all its overseas business after signing a 100million pounds network and voice contract. Through this network upgrade, Nick Folkes, Tesco’s IT director, commented, that the company will be able to standardise key finance, human resources, data warehouse and sales applications across the whole worldwide operations. The Cable Wireless network will connect 1,800 Tesco sites in the UK, stores in more than 14 countries and 440,000 employees worldwide, hence, significantly contribute expenditure reduction from reducing call costs to savings on staff travel expenses. He remarked â€Å"Our aim is to have a common technology platform in tandem with common business processes so that we remain competitive as we continue our expansion abroad† (Kamath, J. 2008). Smart human resource management is also important key of Tesco’s business performance. The company has selected Red Prairie’s workforce management solution to manage its global store staff, which will enable Tesco to improve customer service by aligning customer traffic with employee schedule. â€Å"Ultimately, it will improve our business by increasing store productivity, and supporting revenue growth† said Dave Briggs, programme manager for Tesco (Apparel Magazine, 2008). Tesco has been proved a very good innovator as bachelor’s placement’s in Tesco yet further proved its innovation temperament which has seen in Tesco as they have the ability to mold according to the trend whatever are the market need as it become the first who protect the convenience outlets in UK, it’s one of the biggest innovation of all is the Clubcard Loyalty Program, Another great innovation done by Tesco was in supply chain management in which it partitioned the loaders according to the delivery like 1 chamber of frozen foods, another ambient products in only one truck, another innovation is the collection of data from customers on every purchase to use this information to offer the draw on product range, Voucher mailing to the customers according to the purchasing behavior of the consumer so that it can return to Tesco. Continuous analysis on the data gathered from the market it innovates its products like once Tesco got to know that nappies does not have market share so they researched on it and introduced the club offering baby advice on pregnancy and motherhood. With this around one fourth mother and baby market was captured by the company (Strategic Direction, 2008). Company has that much strength that it wanted to collaborate with the US grocery market where other European companies fear to stand. US market is known as typical market as it produces very luxury products at one end and cheaper products on the other end, but Tesco is the only one who can stand with this giant market as it is UK’s biggest market which ability to attract customers of all social groups. Normally, people in US live near a big supermarket but Tesco bet that it will provide small stores with all needful products which are preferred by the people of US. Tesco look forward to launch Tesco Fresh and Easy Stores in US. These stores will be much spacious to provide all the necessary products under one roof, not like US outlets which does not provide alcohol, pizza’s, snacks etc. Healthy eating is also one of the major fields where Tesco thought to capitalize its money. One of the biggest hurdles is to persuade the US people to behave likewise of the Tesco trend in UK where transportation facility and easy convenience helps people to buy more products especially in the case of perishable goods. Tesco has one more worry in front of it as its credit rating in respect of measuring quality of goods and services has been slumped where rivals were resurgent in this process (Strategic Direction, 2008). So Tesco is proved to be a good innovator which makes it in building strong reputation and brand name in the UK market providing all the necessary products under one roof. Tesco strategies makes it possible to compete it in the market like its brand strategy, price strategy and its thorough analysis of the market like Product life cycle analysis etc. making Tesco a competitive brand. According to the Product Life Cycle when a new product is launched or old product is launched in new market generally there is no competition expected at this stage and a high expenditure is needed in market research, launch cost and market test so the product may incu r financial losses in early stage. The same situation was there when Fresh Easy chain of Tesco incur a loss of $106.8 million. It is clear that there were very low sales of these products so the weakness of the sales raises questions about the expandability of this format, what Tesco is into these days. So Tesco should limit the expandability at such a large scale in new market. Balance Scorecard: In 1998 Tesco’s balanced scorecard was introduced and now it is known as Steering Wheel and it is the main driving tool for the business. It has helped Tesco to achieve a lot and it is followed from the board room to the shop floor. The steering wheel is annually reviewed and it ensures that Tesco is achieving its goal and also it ensures that Tesco meet the demands of organizational strategy. Although customers are not much aware of the balanced scorecard but the staff follows it strictly on the data which is collected weekly. Store level scorecard is given to the manager of the stores in which contains the quarterly corporate scorecard. However a strong link is there between the corporate level scorecard and the corporate level scorecard because of this whole data is collected by various systems and mechanism. Top management monitor the performance and look for the problem areas, after identifying the problems local management are asked to resolve and seek the improvement.

The Importance of Helping Friends in Leo Lionnis, Frederick and Swimmy :: Frederick Swimmy Essays

The Importance of Helping Friends in Leo Lionni's, Frederick and Swimmy In many of Leo Lionni's children's books, one of his characters is always helping a fellow friend out. For example, in Frederick and Swimmy, there are characters that help others to survive. These characters possess human attributes and carry across important messages to the reader. Frederick shows that just because he is not working with the other mice does not mean that he is not helping out. He is just doing it in another way. While the others are working to gather food for the winter, Frederick just sits there and takes in other things such as the "sunrays for the cold dark winter days", and "colors for the winter is gray", and finally words "for the winter days are long and many, and we'll run out of things to say"(3). The other mice may not believe what Frederick is saying, however in the end when they are cold and the sky is gray, and they are at a loss for words, they turn to Frederick who in turn shares with them everything that he had been saving up. By Leo Lionni writing this, he was able to show that people can help out others in many ways. Although Frederick was not doing the same things as the other mice, in the end he helped his friends to survive the long, cold, dark winter. What Frederick achieves by gathering his supplies, Swimmy achieves by being smart. In Leo Lionni's book, Swimmy, the odd fish is the one who in the end helps the other fish from being eaten by the big "tuna fish" who is "swift, fierce, and very hungry" (75). Swimmy does not want to have to constantly worry about being eaten by the big fish, so he comes up with an idea to help all of the other little fish survive the large fish. He has them all join together to become one big fish and he is the eye. By Swimmy coming up with this idea, he is able to protect all of his friends. Without his help who knows what would have come of all the other little fish. Although not all of Leo Lionni's books portray how friends can help other friends survive in different ways, Frederick and Swimmy are great examples of this.

The Great Gatsby :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  In the novel The Great Gatsby by F. Scott Fitzgerald, the characters Jay Gatsby and Daisy Buchanan are said to be in love, but in reality, this seems to be a misconception. In this novel, Fitzgerald portrays the themes of love, lust, and obsession through the characters of Jay Gatsby and Daisy Buchanan, who confuse lust and obsession with love. By the end of the novel however, Jay Gatsby is denied his â€Å"love† and sacrifices his life for a woman who never gives him a second thought.   Ã‚  Ã‚  Ã‚  Ã‚  Jay Gatsby was a wealthy businessman who gained his money through the illegal practice of bootlegging. Gatsby’s love interest, Daisy Buchanan, was a materialistic woman who was married to the domineering Tom Buchanan. She seemed to care for nothing more than money. Gatsby was in love with Daisy, and went to all lengths to win her over. Gatsby’s only motivation for obtaining all of the money that he did was to become appealing to Daisy. Since Daisy was married, the idea of love between Gatsby and Daisy was forbidden. This very concept made the relationship all the more desirable. Gatsby becomes obsessed with his relationship with Daisy to the point that he was delusional. His only objective was to win Daisy back.   Ã‚  Ã‚  Ã‚  Ã‚  When Tom learns of Gatsby and Daisy’s secret affair, he is outraged.

When he realized that he had lost control of Daisy, he panicked but because he senses that Daisy does not love him anymore and, therefore, he cannot control her.   Ã‚  Ã‚  Ã‚  Ã‚  Lust can completely overpower a person until they become controlled by it. By the end of this book, Gatsby becomes obsessed with his lust for Daisy. He wanted so much to have her, this she consumed every aspect of his life. He thought that he could turn back the hands of time and make Daisy love him again, but this proved to be simply impossible. Daisy was not willing to risk her social status for love, proving the of money and power was more important to her than love.

Our Town :: essays research papers

Our Town, by Thornton Wilder, is an American classic, expressing with warmth and humor the eternal truths of human existence. It is a heartening, compassionate glimpse of that time before the Great Wars; before our innocence was lost forever. From the time of its first performances in 1938, it has continued to be regarded as one of the best representations of life in America and of the richness of our theatre world. For decades it has remained a landmark of theatrical craftsmanship and a loving picture of American life. Winner of the Pulitzer Prize, Our Town depicts pathos set against a background of centuries of time, social history, and religious ideas. As the Stage Manager (who functions as a Greek chorus in the drama) says: "This is the way we were in our growing-up and in our marrying and in our doctoring and in our living and in our dying." Our Town is set in 1901 in Grover's Corners, New Hampshire, where the Gibbses and the Webbs are neighbors. During their childhood George Gibbs and Emily Webb are playmates and their lives are inextricably woven together as neighbors' lives are likely to be. But as they grow older they pass into a state of romantic (and embarrassing) interest in one another. George proposes to Emily in the drug store over an ice cream soda, and they are married with all the good folks of Grover's Corners in attendance. But George and Emily's happiness is short-lived. Emily dies in childbirth and is buried in the town's cemetery on a rainy, dreary day. There she is reunited with those friends and neighbors who have died before her, and who help her acclimate herself to her new existence. In one of the most vital scenes in modern theatre, the peace and quiet of death, which can never be understood by the living, is portrayed. Our Town is not just about Emily and George and, indeed, is not just about a small town in northern New England a hundred years ago. Our Town is a play about what we (and Thornton Wilder) thought America and Americans were. As we are about to take a head-long leap into the next century we are forced, not only to look ahead to what we might become, but to turn and look back at what allowed us to arrive at this threshold of the new millennium.

Alternative Education

Alternative Education is expected to meet the needs of those students who are not ensuing in conventional setting. Students are provided with several options that can lead to graduation. They are offered with support services that are essential to their success (Fantini, 2005). Alternative education has models, which are based on the programs philosophy and the desires of the students (Fantini, 2005). There are those that follow a community affiliation model that features alliance with the larger community.Some combine academics with a vocational intervention that focuses on making school more meaningful at the same time preparing students for the workforce (Cantrell, 2001). The programs offered range from actual schools to programs within schools to single classrooms. By year 2000, it was estimated that over 15 percent of the students enrolled in public education and in some countries, a student attended a public school that he wanted.Since 1500, there have been private schools, ins ular schools or home schooling alternatives for those, who could manage to pay for himself or herself or whose beliefs dictated an exacting loom to education. Current history Alternative schooling has become widely important especially in public schools. It originated in United States but it is gaining popularity in other nations (Greene, 2006). The developments that we see in these schools originated from an effort of parents and teachers.They were experimenting how they can discover better ways of educating their sons and daughters and amalgamate educational ideas from some of the acknowledged educational leaders. It is important to note that practices developed in early schools of choice are contributing to local, state, and national efforts to improve public education in all countries (Fantini, 2005). Alternative schooling that has succeeded for more than thirty years is not only considered to be effective in teaching all kinds of students but also highly attractive to parents a nd students (O’Brien & Thesing, 2001).

Major regions of the brain and their functions on behavior Essay

The brain is a complex structure that is divided into specialized parts or regions that perform specialized function. The importance of specialization and brain parts division is not only in brain processing information and generating responses, but the specific impact on behavior of an individual generated by each specialized part. In this regard, the brain has three main regions: cerebral cortex, limbic system and the brain stem (Charles, 2002). The brain stem is the most primitive part of the brain that is located at the joint where the spinal cord enters the brain (Charles, 2002). This part of the brain contains such sub-parts as reticular activity system, medulla and the Pons. The main function of this part of the brain is for autonomic functions deemed as necessary for survival such as health, food, shelter and security seeking behaviors. For instance, when a person falls ill, the brain stem triggers off the course of action to seek medication or health care, thus such an individual shall move towards the hospital premises than to any other direction of food or security. The cerebral cortex is brain region that is on outer part that covers the brain (Charles, 2002). By virtue of covering the brain, the cerebral cortex is considered as the largest part of the brain. The behavioral function of the cerebral cortex involves higher cognitive processes such as memory process that enhances language, thought and learning. Therefore, behaviors such as performance in academic work, ability to retain and remember, verbal fluency and speech development are controlled and generated by the cerebral cortex. Limbic system (Charles, 2002) is the third region of the brain with structures such as hippocampus, thalamus, amygdale and hypothalamus. This part of the brain is responsible for emotional related behaviors of individuals such as motivation, memory functions, and physiological functions. For instance, amygdale is responsible for behaviors such as anger, fear and aggression. The hippocampus sub-structure involves the functions of memory such as information coding and processing into short term and long term memories. Hypothalamus is responsible for emotional behaviors such as hunger, sexual feelings, thirsty and reproduction behaviors. The sensory process as these scenarios unfolds The process and action of hitting the ball produces a cracking sound that travels through air to the ears as a sound sensory organ. The sound message is received and conveyed by ears sensory nerves to the central nervous system (CNS). The central nervous system in return initiates nerve impulse to send the message to the brain. In the brain the thalamus located within the limbic system received the message through sensory receptors found in peripheral nervous system and then forwards the message to the cerebral cortex for analysis and interpretation and then generate feedback message to the sight sensory organs (Albert, 2002). After interpretation of the of the ball sound in the brain by the cerebral cortex, the message is generated back through the same avenue that to the thalamus that will send impulse to the sight sensory organ: eye. The eyes muscles shall be involved in a reflex action to adjust and pay attention to the ball that has been hit. Therefore, ball movement is traced by the eye. However, since the eye does not have the capacity to catch the ball apart from observing it; the sight sensory nerves within the eyes send a message to the brain to prepare necessary mechanism to catch the ball (Albert, 2002). Once the message has been generated by the sight sensory nerves to the brain, the brain through thalamus receives the message through the sensory receptors found in peripheral nervous system and then forwards the message to the cerebral cortex for analysis and interpretation. After analysis and interpretation, the cerebral cortex sends back the message to thalamus which in turn stimulates the concerned organs through responsible neurotransmitters to prepare muscle action to catch the ball as it land. The timing of the ball is entirely an initiative and is dependant on cognitive abilities of the individuals (Albert, 2002). Reference Albert, B A.
