Starts Business Productivity Growth Hypothesis In this assignment, we will attempt to study the effects that difference in Income Ratio (henceforth known as I.R.) between the years 1980 and 1990 have on the Productivity Growth (P.G.) during the same period of time. The Income Ratio of one specific year can be found if we take the average income of the richest faction of a country (the richest 20% of the population) and divide it by that of the poorest faction (the poorest 20%). In this assignment, the Income Ratios that were used were those of 13 different countries. The I.R.'s on both 1980 and 1990 were taken for all these countries and, to find the difference between them, the I.R. for 1990 was divided by the I.R. for 1980, for each country. These new numbers illustrate the change of I.R. between the two years so that we can compare how the P.G. changes in relation to the changes in the I.R.. On this assignment, we use inductive reasoning to examine the data and find a theory (a hypothesis) that would combine the data given in a way that would make sense, based solely on our data. How do we know if the theory that we formulate makes sense? In this case we will plot the points (derived from the column I.R. 1990/1980, going on the x-axis, and the column Productivity Growth 79-90, on the y-axis). According to how the points are on the graph in relation to the Average Point (0.94,1.45) (point that is an average of all values and which divides the graph into four Quadrants), if 80% of these points are where they would be expected to be to conform to the hypothesis, then there is no reason to reject this hypothesis. If, on the other hand, the majority of the points does not conform to our hypothesis (are not where they were predicted to be), then it is rejected. Another method of reasoning frequently used by Mainstream economists is deductive knowledge, as opposed to inductive, described above. Their theory is formulated and only then it is applied to the data. Their theory on this subject suggests that productivity within a country grows when the population has incentives to work harder (or to work more). When the gap between rich and poor increases (an increase in I.R. form 1980-90, resulting in a larger ratio on the column I.R. 1990/1980), so does the population's eagerness to work, therefore increasing the Productivity Growth. Since when one variable goes up the other also goes up, there is a positive (or direct) correlation between the two. Mainstream economists use deductive reasoning to deduce that there exists a positive correlation between the two factors. In short, their hypothesis is that when the Income Ratio increases, the Productivity Growth also increases, since people are more motivated. For this to be true, we would expect a line going up and to the right on the graph, passing by Quadrants II and IV. Most points (80% or more) would have to be on these two Quadrants. This, however, is not the case (see graph), since only about 30.77% of the points plotted satisfy these conditions. Since the original hypothesis was rejected, we might want to see if there is a negative correlation between the two variables (that is, as one goes up, the other goes down). Our new hypothesis would then be as the Income Ratio increases, the Productivity Growth decreases. Then, in the case of a high I.R., people in lower classes would rationally start to feel insecure and that their work is not being recognized by society, therefore losing motivation and producing less. In this case, since there's a negative correlation, one would expect the line on the graph to go downwards, from left to right, passing on Quadrants I and III. If this hypothesis were valid, 80%+ of the points would have to be on these Quadrants. This is also not the case, for only 69.32% of the points are on the appropriate Quadrants. Like the first, this second hypothesis also has to be rejected. After analyzing these two relationships and seeing that neither is valid, we conclude that there is no direct relationship between the two variables tested. That does

Third Conjugation -isc Suffix Type Italian Verbs

Third Conjugation -isc Suffix Type Italian Verbs Most Italian verbs are regular verbs, meaning they are conjugated following a regular pattern. But there is a special group of third conjugation Italian verbs (verbs ending in –ire) that requires the suffix -isc- to be added to the stem of all three singular (io, tu, lei) and the third-person plural (loro) forms in the present indicative and present subjunctive tenses, as well as the second and third person singular and the third-person plural forms of the present imperative tense. One good example of such verbs is finire (to finish). Present Indicative io finiscotu finisciegli finisceessi finiscono Present Subjunctive che io finiscache tu finiscache egli finiscache essi finiscano Present Imperative finiscifiniscafiniscono Other verbs that need the -isc- suffix and are conjugated similar to finire include capire, preferire, pulire, suggerire, and tradire. Unfortunately, there is no way to know which third conjugation verbs are isc verbs. Your only option is to commit these verbs to memory. Interestingly enough, in some classic grammatical systems, -isc type verbs were considered a fourth conjugation. Optional -isc- Verbs For certain -ire verbs there is a choice as to whether -isc- is inserted or not when conjugating. The most common include: aborrire (to abhor, to loathe)- io aborro / aborriscoapplaudire (to clap, to applaud)- io applaudo / applaudiscoassorbire (to absorb)- io assorbo / assorbiscoeseguire (to carry out)- io eseguo / eseguisco(to swallow (up), gulp (down); engulf)- io inghiotto / inghiottiscolanguire (to languish)- io languo / languisco(to lie)- io mento / mentisco(to nourish, to feed)- io nutro / nutrisco Different Forms, Different Meanings Some -ire verbs not only have both forms (that is, they are conjugated both with and without the suffix -isc) but take on diverse significance. For example, the verb ripartire: io riparto (to leave again)io ripartisco (to divide)

The third chapter analyzes the performance of TUI and it's those features that contributed to achieve the No.1 position in tourism and shipping industry. It further explains the key unmatchable factors that have made TUI far ahead of its market competitors. In the end the current structural changes in different business fields are discussed and TUI's response to these changes with its corporate strategies and business models. In order to complete this paper, a meticulous research has been done on available information on the subject of tourism and contribution of TUI in this field. A variety of case studies and few books and online journals were reviewed. Online available resources are given special precedence than available library books because there is no specific book available about a particular tourism company. It is the biggest limitations of this research that in co mparison to available web-based resources, hard copy books are not readily available specifically about TUI. TUI is an abbreviation of Touristik Union International that was established in 1968. As Preussag AG, it remained a renowned organization in transportation and industrial sector till 2001 when it became a 100% subsidiary of Preussag AG. In next ear, Preussag AG was transformed into TUI AG. During next few year

Ethical Hacking Essay Example | Topics and Well Written Essays - 500 words - 3

Ethical Hacking - Essay Example It can be used to protect an organization against an attack because it spots out and potentially prevents intrusions that breach the system’s firewalls or those that occur behind the local area network (LAN) or the firewall (IATAC, 2009, p.3). Thus, IDS can provide organizations real-time or near-real-time monitoring of a host or a network and defend them from hacking. IDS cannot always detect footprinting stages. The wrong results in an IDS are categorized into two kinds: false positives and false negatives (IATAC, 2009, p.4). False positives happen when an IDS wrongly sees a problem with benign traffic (IATAC, 2009, p.4). False negatives take place when malicious traffic is not recognized by the IDS (IATAC, 2009, p.4). When this happens, hackers’ footprinting efforts can enter the system and evade the systematic monitors of an IDS. Also, an IDS cannot evade successful social engineering tactics. These tactics gathers useful information about the system that can be used to determine vulnerabilities and other useful information. Two scanning and enumeration tools that the organization can use are Port Scanning and Null Session tools. Port scanning can be done by Nmap- it is a program made for network mapping tool. Nmap does different network functions, such as fingerprinting a system, finding ports that are common to a specific network device, and determining the servers, such as recognizing that System B is actually a Solaris server. The Windows Server Message Block (SMB) protocol provides free information. Null Sessions are not on by default in Win XP, Server 2003, Vista, and Windows 7 but open in Win 2000 and NT. Some of the Null Session Tools are Dumpsec, Winfo, Sid2User, and NBTenun 3.3. Scanning and enumeration can be taken to the next level through using vulnerability assessment tools that respond to scanning and enumeration activities. Vulnerability

Maximisation of profit Article Example | Topics and Well Written Essays - 5500 words

Maximisation of profit - Article Example When small groups of people come together and work on a project, they invariably have to analyze as to what their mission and goal are. Organizations are usually classifies into different types like public sector (Central governments, state government run offices, schools, colleges, public welfare systems), private sectors (small business partnerships, limited companies, cooperatives, multinationals etc.), Quasi-Governmental organizations, Organizations in the charitable sector and even the churches and trade unions can be referred to as organizations. (N.Kumar, 1997) Hence, every organization issues a mission statement, which includes the purpose of setting up the organization. In social sciences, organizations are perceived from different dimensions. The general study of how an organization works is termed as organizational behavior or analysis. The whole of organization's behavior revolves only around one aspect-its goal. Every organization should have, irrespective of the field i t operates in, a distinct goal. (N.Kumar, 1997) A goal, not only gives them a direction of persuasion, but also gives the much required motivation to the employees to work towards it, thereby helping them achieve their potential along with the company's growth. Likewise, a conceived state of an organization in a stipulated amount of time is referred to as 'Vision'. 'Vision' is extremely crucial for an organization as it gives a glimpse of the state of the organization after a certain period of time to the employees and stakeholders. 'Vision' can be taken as a benchmark for the company's performance in the future and can be used for comparison of various results recorded by the company. (Davenport Hines, 1990) Private-owned organizations usually have profit-maximization as their sole objective. (Susan Grant, 2000) However, many economists have different views over how an organization's objective should be formulated. Different people have come up with different theories over the issue of organizational objective. Many of them clashed, many of them overlapped and new theories were born out of the overlapping theories, but a general consensus is achieved that profit-maximization should be the sole objective organization though other objectives cannot be safely put aside. In this dissertation, I'd like to analyze the various theories put forward by economists and then draw a suitable conclusion from the same. I will also be studying a few patterns of various industries by taking certain specific examples of how a few companies overcame different situations keeping in their minds profit-maximization as their sole-objective. Literature Review As said above, it is imperative for an organization to identify its objectives before venturing and investing resources into the venture. So what is/are the goals a financial manager in a company will seek. In the first impulse, the only objective, which comes to, the mind, is profit maximization. Any business enterprise aims at earning profits; hence, it may be argued that profit maximization should be the sole objective of the organization. It is needless to say, that earning profits sustains the company's existence and can motivate the company to expand its market and

Wal-Mart China: Sustainable Operations Strategy

Wal-Mart China: Sustainable Operations Strategy 1. Explore through the literature the concept of (Business) sustainability and explain it briefly. Also using references on Operations Strategy describe what sustainability in operations strategy means. Traditional cost management models tend to only focus on production costs, whilst ignore products cost of design, development and customers using. In other words, the business concern visible costs and ignore intangible costs that means the destruction of the surrounding environment such as the cost of social responsibility during production the process. Thus, enterprises want to win the competition, they must change the traditional model of cost management and maintain the lowest cost in the life cycle of product. A broader perspective of product life cycle cost which includes social responsibility cost should be a part of business operations strategy or should be a part of business sustainability strategy. Business sustainability is a business approach have policies of environmental and human rights which means the business creates long-term shareholder value from no negative influence opportunities and managing risks on global or local society, environment, community and economy [3]. Smukowski [2] claimed that the concept of business sustainability is a prior plan of the long-term viability and optimizing resource needs, reducing environmental, energy or social impacts which will not damage the profitability of business. It can be summary from above that sustainable business means the enterprise consider not only financial factors, but also more comprehensive concern the impact of environmental and resource efficiency. 2. Discuss what Sustainability means to Wal-Mart, Wal-Mart China, and Wal-Mart Chinas current and potential customers. What would you see to be a balanced definition of sustainability for the business? Answer: (1) Wal-Mart In order to run business sustainability, Wal-mart combined value and service concepts of innovative operational strategies and set three sustainability objectives including more efficiency of vehicle fleet, reduce waste and energy saving. First of all, to combine value and service of its innovative operational strategies involve 14 SVNS made Wal-mart became the largest organic seller and the largest organic cotton purchaser. In addition, Wal-mart also through its integration of supply chain and ROHS compliance which including supplier or vendor selected and scored to achieve business sustainable aims. For instance, Wal-mart sold 110 million compact fluorescent lighting successful with its partner called GE. (2) Wal-Mart China In term of Wal-Mart China, its through 5 SVNS reach business sustainable. First of all, the strategy of sustainable store and operation can help Wal-Mart China reduce cost and decrease Wal-Mart Chinas footprint of operations. Secondly, to develop sustainable products such as food, electronic textiles and product packaging extend its business sustainability supply chain and compliance. Thirdly, to enhance efficiencies of its supply chain not only reduce cost but also footprint of whole chain. Fourthly, to make a good communication with its stakeholders is another critical issue of its business. Fifthly, Wal-Mart China also through share learned experiences with its supplier or vendor to make its sustainable supply chain more successful. Sixthly, Wal-Mart China employed T5 energy saving light bulb and double sides copy to decrease its energy waste of its business. Lastly, Wal-Mart China promotes the product which is an energy efficient bulb for its customers that is also an activity of business sustainability. (3) Wal-Mart Chinas current Wal-Mart Chinas sustainable logistics centers helped its reduce 31 tons of CO2 emission per year. For example, T5 light bulbs can save 20 to 30 percent energy per day in warehouse areas and resting places and to use solar energy and wind power generator can 7,300 kilowatt hours per year. In addition, Wal-mart encouraged its customers to use reusable shopping bags through some prizes including special express checkout line. Finally, Wal-Mart Chinas merchandizing group still continuing builds sustainability measure tools for supplier selection and some on going evaluation of purchase quantities which can enhance its suppliers efficiency of sustainability. Wal-Mart China also continuing creates innovative initiatives of sustainable and implements best practices for communicating to all of its stakeholders. (4) Potential customers If customers can choose Wal-marts sustainability products which not only improve the personal activity of environmental but also protect the Earth. Although the sustainability products price might higher than others, it still have some advantages such as reduce cost of electronic, long time for use and non pollution. According to the article, T5 energy saving light bulbs could save about 20 to 30 per cent energy which means its can also reduce the cost of electronic of 20 to 30 per cent. 3. Identify the distinguishing features of Wal-Mart Chinas distribution system and operations. Explain how it achieves relatively high availability with similar levels of stock to other companies. Answer: In order to provide high quality products for customers and the commitment of businesss operations strategy, Wal-Mart China combines their high employee productivity, latest technology, experienced co-transport sector, an efficient private truck fleet and distribution center operations which not only is an advantage of Wal-Mart Chinas inventory management but also increase efficiency of loading and delivery. According to the article, there are some advantages of Wal-Mart Chinas distribution center: (1) Sustainable logistics centers First of all, Wal-Mart Chinas distribution center uses T5 light bulbs which can save 20 to 30 percent energy per day in warehouse areas and resting places. Secondly, in order to reduce energy waste, Wal-Mart Chinas distribution center maintains control their air conditioning and heat recycling systems temperature. Thirdly, there are 25,550 kilowatt hours saving caused by ten solar energy water heaters which provide 1.7 tons hot water per day. Lastly, Wal-Mart Chinas distribution center use solar cells and wind power station to make up to 7,300 kilowatt power per year. As a result, each Wal-Mart Chinas distribution center also decreased CO2 by it. (2) Outsourced a standardizes trucking fleet Individual supplier ship was lower than expected fill rates. Wal-Mart China outsourced an efficient private trucking fleet which deliver products from DC to DC or from DC to SC. It not only helps Wal-Mart China achieves a well inventory management but also reduce out of stock rate. In addition, in order to make its trucking fleet teams more efficiency, new electronic technology is used in its logistics management [6]. First of all, Wal-Mart China through the electronic technique of satellite, GPS controls the state of transport. Secondly, Wal-Mart China also uses the electronic technique of GIS which provide digital electronic traffic map can suggest the best route of its delivery. Thus, it can be concluded from above that Wal-Mart become a world-class company is not accidental. Advanced electronic technique of Wal-Mart Chinas distribution system not only increase efficiency of its products delivery, but also decrease the situation of out of stock. (3) Centralized management of returning products Wal-Mart Chinas distribution system also has an advantage of centralized management products which has quality problems, slow sales or obsolescence. These products will also be returned to vendor by Wal-Mart Chinas distribution system. In summary, it is clear that Wal-Mart Chinas distribution system and operations can offer a stable inventory which is part of Wal-Mart Chinas safety stock. By way of replenishment products intensively from distribution center, it not only reduces time of out stock but also increase the circulating of goods. In addition, as Wal-Mart China has a very complete and standard systems or process of distribution such as outsourced a standardizes trucking fleet, new electronic technology and centralized management which also let Wal-Mart China become a highly competitive advantage of Chinas retailer industry. 4. How sustainability should be incorporated in the process of selection and evaluation of suppliers/vendors? Answer: In order to achieve business sustainability successful, both enterprise and its suppliers or vendors have responsible of their roles. First of all, enterprise should offer the requests of sustainability, and then try to find the suppliers or vendors who have production techniques of sustainability. Furthermore, to have a good communication and collaboration including share learned experiences with its suppliers or vendor is a critical part of objectives of sustainability. According to the article [4], in order to achieve ROHS compliance, Wal-Mart adopt ROHS regulation standard in some of its operations including supplier selection and product selection. For the first example, P G which is a large international supplier has a long standing working relationship with Wal-Mart in other parts of world including the U.S.A. It has a sustainability program concept called ensuring a better quality of life for everyone, now and for generations to come throughout its worldwide operations [4]. As can be seen from it, the sustainability development program for P G not only is a slogan, but also is a commitment for its customers. For the second example, Blue moon which is a Chinese national chemical products company supply some soap and cleaner in china. Blue moon also has a sustainable program of its products called Protecting the environment is protecting all of us. Our products deliver not only cleanliness but also protection to our customers [4]. In order to achieve its object of sustainable, biodegradable materials which meet a green environmental requirements used in Blue moons products. For the third example, Wal-mart China also created a initiative sustainable objective which called P2E2 program allowed suppliers to quickly and inexpensively equip their factories with cost saving equipment [4]. In order to continuing meet sustainable objectives, Wal-mart builds a sustainability evaluation tools which used in its supplier selection and product or material purchase. For instance, Wal-mart china had implemented a packaging score to measure and calculates efficiency and objective. In the end, this program also a 13 per cent cost reduction in Wal-marts packaging. It can be summary, if the enterprise wants to achieve, to integrate whole supply chain members such as suppliers and vendors are very important. In other words, to develop sustainable supply chain strategy is the only approach to make business sustainability which not only creates a perfect brand image for customers but also protects the Earth. 5. How sustainability can be improved in Wal-Marts distribution and retail operations. Answer: According to the article, Dong [4] asserted that sustainability will be differentiating factor between a good enterprise and a great one. (1) Energy efficient lighting Wal-mart used T5 energy saving light bulbs which could save about 20 to 30 per cent energy in its warehouse or space of rest. (2) Less waste of air conditioning and heat recycling system Wal-mart maintained the temperatures of its air conditioning and heat recycling system which also is an approach of energy saving. (3) Alternative energy Wal-mart used ten solar energy water heaters which can save up to 25,550 kilowatt hours each year to produce hot water. Wal-mart also used solar cells and wind power generators which can provide 7,300 kilowatt hours per year. These alternative energy not only save Wal-mart cost of electronic but also reduce 31 tons of CO2 emissions every year. (4) Outsourced third party logistics Outsourcing a standardized trucking fleet not only improve Wal-marts effective of shipments but also reduce the risk of goods traveling. (5) Reusable shopping bags Wal-mart encouraged its customers to use reusable shopping bags through some prizes including special express checkout line. (6) Offer two energy efficient bulbs Wal-mart China offer two energy efficient bulbs for the price of one and work with local suppliers in its region. After this, Wal-mart China accepted responsibility and the associated cost of the safe disposal of fluids. (7) Batteries placed In order to solve batteries placed problems, Wal-mart provided a recycle place for customer to deal with it. (8) Packaging reduction Wal-mart china had implemented a packaging score to measure and calculates efficiency and objective in its apple suppliers. In the end, this program also a 13 per cent cost reduction in Wal-marts packaging. As can be seen above, generally speaking, business sustainability concept including logistics, marketing and supply chain has many benefit of the enterprise. Refer to the article; the authors [4] believe that more economical situation caused by more sustainable options. In other words, it not only reduce cost of operations but also make more loyal in long run of its customers.

Dramatic Techniques in Shirley Valentine by Willy Russell :: Shirley Valentine Willy Russell Essays

Dramatic Techniques in Shirley Valentine by Willy Russell How do the dramatic techniques use in the play help the audience to understand the importance of Shirley’s transformation? You should refer to the significance of the play’s social and historical (settings, attitudes to women SHIRLEY VALENTINE Task: How do the dramatic techniques use in the play help the audience to understand the importance of Shirley’s transformation? You should refer to the significance of the play’s social and historical (settings, attitudes to women, attitudes to marriage, expectations of life, etc) context and the literary context (kitchen-sink drama, comedy, tragedy, drama, etc). The play ‘Shirley Valentine’ was written by Willy Russell. Russell was born in 1976, near Liverpool. He left school when he was fifteen and did a variety of jobs before becoming a writer. Originally he used to be a songwriter, performing in his late teens. By the time he was twenty he decided to become a playwright rather than his desired option of teaching. In his first eighteen months schools loved his work and he decided that he was successful enough to do it fulltime. â€Å"Shirley Valentine†, is the story of a middle age woman living in Liverpool and her change in life. Russell explores the usage of different dramatic techniques to tell a complex story. We the audience are in contact with Shirley from the beginning, because she talks to the camera. This forms a friendship between Shirley and the audience. We become her confidante. Other dramatic techniques used by the playwright are the use of Flashbacks and Voiceovers. In flashbacks Shirley would be doing something and would drift off talking about something that had happened earlier on in the day or a previous day, so we would get all the background information, on what has been going on. It also highlights the important events in her life to show us how she got to this point in her life. In Voiceovers Shirley would express her true feelings about someone whilst they would be talking about the thing that Shirley is expressing her feelings about. The opening credits depict a series of fifteen sketches that show Shirley doing her everyday routine of domestic chores, with no enthusiasm. Shirley if cleaning and cooking, this tells us what her life is like, boring. You could see that she is tired of living out her life in an ordinary marriage, with very little going on, she has all this Unfulfilled Potential which she desperately wants to overturn. The words of the soundtrack are very cleverly adapted to the sketches shown. They tell the everyday life story of a woman that has
