George W. Bushs Faith Based Initiative and the Separation of Church an

George W. Bush's Faith Based Initiative and the Separation of Church and State Clause Nowhere in the U.S constitution or any other official documents  does it say that there must be strict â€Å"separation of church and state†.   This clause was used by Jefferson in his letter to the Danbury Baptist Association of Connecticut on January 1, 1802 (Truthwalk 1).   After being revised six times by one of our founding fathers, James Madision, the first amendment now states that,   â€Å"Congress shall make no law respecting an establishment of religion or prohibiting the free exercise thereof..." (Parsons 40).  Ã‚   Did the fore fathers intend the first amendment to keep religion out of government, or did they want to create a law that stated religion was a free choice moreover preventing the government from forcing one religion upon the people of America. When hearing the phrase â€Å"separation of church and state† one thinks of controversy.   Every other day you hear of something on the news regarding, â€Å"the separation of church and state,† where is the right place to draw the line? Many issues have arisen in the world today that makes the topic of "separation of church and state" very controversial; however, one of most significant issues is Bush's Faith Based Initiative.   Bush’s Faith Based Initiative has strong separationists crying out â€Å"separation of church and state† all over the news. "Separationists argue that our fore fathers wanted such a complete division between church and state that any government accommodation would be unconstitutional"(Frank Guliuzza, p.116). On January 29th, 2001, right after his inauguration, Bush set up his Faith Based Initiative that would soon provide â€Å"faith-based† organizations with governmental federal fund... ...

Dow Chemical Case

Dow Chemical Case Question 1 Polyethylene is the world’s most widely used plastic. Polyethylene plastic’s principal application was in packaging, from trash bags to milk jugs. It was widely used in the manufacture of everything from trash bags, picnic cutlery and garbage pails, to plastic toys. Polyethylene also replaced glass, wood, and metal in certain applications. There were three types of polyethylene, Low-density polyethylene, High density polyethylene and Low linear density polyethylene. Polyethylene produced from ethylene. Ethylene is produced from oil or natural gas. Ethylene plants separated either naphtha molecules (derived from crude oil) or ethane molecules (derived from natural gas). The ethylene derived from this process was used to produce polyethylene. The critical success factors in this business were capital intensive and economies of scale. Polyethylene was a global commodity product and pricing worldwide typically fell into a narrow band. The demand for polyethylene was large because it was the world’s most widely used plastic and polyethylene customers were typically small and medium-sized plastic processing companies. The big Risks in the industry: * The raw material risk – Cracking naphtha (the raw material derived from crude oil) required much more energy, manufacturing intensity, and equipment than cracking ethane (derived from natural gas). Supply of primary materials and electricity are crucial to success of polyethylene production. * Cost risk – large plant sizes and the need for economies of scale rendered the ethylene industry highly capital intensive. A plant for cracking ethane was estimated to hundreds of millions and the cost for a plant for cracking naphtha is double. Capacity additions or reductions could significantly affect balance of supply and demand, influencing capacity utilization rates, prices, and profit margins. * Ethylene profitability was tightly links to its global operating rate. The ethylene business links to oil companies, governments, pure chemical companies, conglomerates, private investors, and joint ventures. * Competition of polyethylene industry in Argentina and in the global market. The government operator was directly or indirectly financing capital – intensive ethylene plants in order to stimulate downstream business. Some of countries, the government contribute the investment. * The margins for producers of ethylene and first-order derivatives (mostly plastics) were highly correlated because the producers for them were highly integrated. Question 2 The stages of the project: * Stage 1: involved taking control of PBB, which comprised the ethylene cracker and polyethylene plant, and then upgrading the facilities in order to make them internationally competitive * Stage 2: involved acquiring Polisur’s two polyethylene plants * Stage 3: involved building a new ethylene cracker and a polyethylene plant These three stages are closely related to each other. The next stage would be reached only if the previous stages achieved, and the followed stages ensure the success of the previous stages. Acquiring PBB offers Dow the opportunity to enter Argentina market, and this is the first step for Dow to take over control of Bahia Blanca’s polyethylene activities. Dow is bidding not only for PBB in the privatization, but also an overall plan for the development of Dow’s polyethylene business in Argentina. Dow will decide on the price to bid for PBB in the upcoming privatization, the price is based on the valuation of the entire project (stage 1, 2 and 3). The three stages are one big project. Dow’s bid for PBB should not be based solely on the value of Stage 1 of the project. Gaining control of PBB would be the first step in the project. But taking all the factors discussed above into consideration, Dow should value all the 3 stages in order to bid on the PBB project. Dow believed that it had the opportunity to become the number-one player in the Latin American polyethylene industry. To achieve this goal, Dow would also have to acquire Polisur’s two polyethylene plants (stage 2) and expand existing capacity. The expansion of its polyethylene capacity in Bahia Blanca would require the company to build a world-class competitive cracker (stage 3). Doing so would nearly triple PBB’s ethylene capacity. Therefore, Dow had to not only consider what to bid for PBB in the privatization, but also develop an overall plan for the development of Dow’s polyethylene business. Dow had to incorporate the terminal value of each stage of the project. Question 3: The followings are the arguments that support the acquisition of PBB: 1. The whole project will increase Dow shareholder’s wealth. As a public company, the first aim of the management team is to increase the shareholder wealth. The project proposed by the management team is definitely consistent with this goal. And bidding on the PBB is the first stage of the whole project. The exact increase in shareholders’ equity may be various at this point as it depends on lots of other factors ( we will discuss the risk of valuation thought the whole case. , but in general, the management team is confident in the future outlook. 2. The other important strategic purpose of acquiring PBB is that it is the first stage towards consolidating all Bahia Blanca’s polyethylene activity under Dow’s control. The 3-stage project will make Dow to be the leading company of polyethylene in Argentina, even in Latin America because of its MNC background. This will have a long term positive influence in Dow’s stock price as well as shareholders’ equity. 3. Also, as indicated in the case, the demand of polyethylene will increase in the next couple years. Argentina is an emerging market, which is facing a rapid transformation. Dow’s vice president anticipated continued improvement in standards of living, which will lead to increase demand for polyethylene in Argentina, as well as in Latin America. The expected growth in polyethylene demand made PBB a potentially attractive acquisition. 4. PBB right now is a government controlled complex which is going to privatize. For Dow, it is a perfect opportunity to build long term relationship with Argentina government. It will give Dow more opportunities in the market of Argentina and Latin America. Question 4: The followings are the mains risks of the project for Dow beyond the general industry risks discussed in Question 1: 1. Country risk. Argentina is an emerging market. It is widely agreed that when we estimate the risk of emerging market by using the traditional model like CAMP, the result also unfavorable. Some reasons are the market is highly concentrated and integrated. And also the country risk cannot be diversified. So it brings the uncertainty to Dow’s valuation. 2. Political risk. Political risk is part of country risk. It is identified as the potentially adverse impact a country’s environment has on a firm’s future cash flows. And it will affect Dow’s future expected returns and valuation measures. If there is some major political unrest in Argentina, the government expropriates PBB, Dow will face a significant loss. Also, if the Argentina government default on its debt, Dow would face the bad debt which is an huge cost and will drag down the expected cash flows. 3. Economics risk The privatization in Argentina was the progress to control the fiscal problems, like hyperinflation, stagflation and huge fiscal deficits. As an emerging country, Argentina had not developed a healthy financial market within the country. The unstable economy would lead to a huge possibility of default. Another possible aspect was the economics risk of the world. If there was an economics downturn, the huge investment of the project would worth less and Dow will facing difficulties to rise equity to finance the project. 4. Unexpected risk: (1) Unexpected shortage of energy. The industry is really energy intensive. If there is a energy shortage such as the decreased supply of oil, the whole project will face negative return. (2) Unexpected rise in variable cost, such as transportation cost. The unexpected rise in variable cost will have negative impact on Dow’s cash flow. The decrease of expected cash flow will lead the decrease value of the project. (3) There are 3 stages of the whole project. If one of them did not work well, the overall goal will be affected and the whole project would have the risk of failure. Question 5: Given in the case that Dow’s cost of capital for similar U. S. based projects is 10%, thus we chose to use NPV to evaluate the different stages of the project, by discounting each year’s expected cash flow (Exhibit 9, 10 & 11) to the base year-1995. Stage 1 Valuation Given in the case, Dow is bidding on the sale of 51% of PBB, therefore, if we calculate the Present Value of the cash flow, Dow should get 51%. Dow’s total investments for PBB Ethylene cracker and PBB Polyethylene cracker between 1996 and 2000 are $128. 9 million and $28 million in Exhibit 7 from the case. If we compare these figures with Exhibit 9A & 9B investment numbers between 1996 and 2000, they are the same (shown in Table 1); this means that the cash flow of PBB in exhibit 9A is the cash flow after only deducting the investment from Dow. So, we add back Dow’s investment to get the actual cash flow of PBB. Since Dow’s share in PBB is 51%, it gets 51% of PBB’s cash flow and we discount the cash flow. Next we calculate the sum of Present Value of Dow’s investment in each year, and subtract it from Dow’s 51% share in PBB. This number reflects the actual net cash flow been distributed to Dow. The followings summarize the steps of the thinking process: Step 1: Add back Dow’s investment to PBB’s cash flow, this gives the total future cash flow to be distributed among Dow (Dow owns 51% of PBB) and other owners. Step 2: Find the PV of total future cash flows Step 3: Distribute the 51% of the PV of total future cash flow to Dow Step 4: Deduct PV of Dow’s investment from Step 3 The value of Stage 1 is $345. 71 million as shown in Table 2. Stage 2 Valuation In Stage 2, we took polyethylene CFs directly from Exhibit 10, and discount them by appropriate discount rate, and summing up these PV of the cash flows we get the value of Stage 2, $399. 76 million. Another point worth mentioning is the calculation of the terminal value in 2010. Given in the case, the growth is 3. % constant for the project, we took the cash flow in 2010, which is $82 million; multiplied it by (1+g)/(k-g), and discounted it by 16 years to get the present value. Stage 3 Valuation Stage 3 involves building a new ethylene cracker and a polyethylene plant. We summed up the total cash flows of them and find PV of the cash flows in each year. The total of all the PV of the cash flows is the value of Stage 3, $ 993. 69 mill ion shown in Table 4. Now we have the value for each stage, and we get the total of the project, it is worth $1739. 16 million with the value of Stage 1, Stage 2 and Stage 3 are $345. 1 million, $399. 763 million and $993. 690 million respectively, under the assumption that each stage is successful just like Dow has planned. Question 6: There are two ways to do Discounted Cash Flow analysis in an international context. We can adjust the discount rate by adding a country’s political risk premium or, adjust the cash flow of the project. In this question, we will discuss the appropriate method of the project’s discount rate. In a country, the higher risk that investors perceived, the higher discount rate that should be applied to the project’s cash flows. The risks we are talking about are not diversifiable. Since November 1995, the Convertibility Law tied the peso to the U. S. dollar, even thought the market thinks the fixed exchange rate would last for several years, but as the executives of Dow, Virgnar and Marcer need to consider the possibility of future crises. Uncertainty about future currency thus will increase the discount rate of project in Argentina, which means that Dow’s cost of capital is increased. Possible impact of government policies relevant to foreign investments is another issue, example increased tax rate. This will leave Dow with a lower investment return than before. In practice it is often difficult to quantify the likelihood and impact of political risk on international investments; given US and Argentine Yields in the case, we can adjust the discount rate by adding the sovereign yield spread between U. S. and Argentina. The idea is that the bond spreads between two countries with same maturity reflects country risk. The country with the higher yield in this case is Argentina; it offers approximately 10% more than the U. S’ yield shown in Exhibit 12. The reason behind that is Argentina has a higher country risk than U. S. , so it has to offer a higher yield in order to compensate the investors for taking additional risks. Therefore Dow should take these additional risks into consideration when evaluating the project. The adjusted discount rate for the project should be 20%, 10% ( cost of capital for similar U. S projects from Q5) + 10% (Argentina’s country risk) and this change in the discount rate will have a big impact on the value of each stage in the project which we will examine later. There are two major advantages of adjusting the discount rate by adding the sovereign yield spread. One of the advantages is the countries’ bond yields are easy to find, observe and access, investors can easily calculate the country risk by subtracting the two bond yields. Another advantage is that the yield of bond is forward-looking, it does not only incorporate today’s condition, also the yield reflects the market’s future expectation of a country’s risk and return so it is a good representation of cost of equity in a particular country. Salomon Smith Barney model is similar to the model that we just described, but with additional inputs and refinements. If we have more information from S&P country sovereign ratings, country ratings, and macro variables, we could adjust discount rate for the project more accurately. Furthermore, the political risk premium that we can add to the discount rate can be scaled up or down based on subjective scores for Dow’s access to capital, susceptibility of the project investment to Argentina’s political risk and the importance of the investment for Dow. Therefore, the more relevant information we have, the more accurate discount rate we can construct to help evaluate the project. Question 7 The calculation process for is basically the same as in question 5, except here we use the cost of capital 20% instead of 10% to discount expected cash flow. Calculation shows in Table 5 (in Million U$). The project worth is $464. 734 which about only 20% of the project value if it located in US. The largely decrease in project value is due to the higher country risk in Argentina than in the US. The higher country risk was reflected in the higher discount rates which lower the present value of the cash flow. In stage 1, the present value of expected cash flow (CFs) is 160. 32 which is 54% lower than the stage 1 value in question 5. The percentage of decrease is lower than the total project value’s decrease, since most of the value in stage 1 was generate from early years cash flow. The country risk in the short run is lower than in the long run. Because in the long run there are more chances for uncertainty events to happened. In stage 2, the present value of CFs is 194. 81 and it is 51% lower than the project value in US which also less than the percentage decrease of the total project value. And this is due to the same reason as in stage 1. In stage 3, the value is $109. 837 which is 89% lower than the question 5’s value. The significant decreasing value is due to the value of stage 3 is mainly from terminal value. Since there are higher country risk and more uncertainty in the long run, stage 3’s long run cash flows ( include terminal value) are heavily discounted which lead to low present value. Question8 Dow should bid for PBB no matter the project is in US or Argentine, since the total project values and stage 1 values are both positive in these two countries. Because Dow is an American company, the shareholders care about the US returns. The Project cash flows and stage 1cash flows are discounted by the cost of capital in US and get positive present values, which mean the PPB will increase Dow’s shareholder wealth. To determining how much Dow should bid, the company should aware that there are some requirements made by the Argentina government. First, the government set the minimum accepted price is 150million U$, which is the lowest range for Dow’s bid. Second, the government requires the bidder to have a statement of net worth of at least 5 billion U$. While, Dow has two other competitors Copesul and Perez also want to bid PPB. However, Copesul only has net worth $929,538,000 and Perez has net worth $1,461,000,000. Even if Copesul and Perez combine to bid PPB, their total net worth around $2,391,000,000 will be smaller than the $5 billion requirement. Therefore, Dow should not been threatened by Copesul and Perez’s bid, and they should not affect Dow’s biding strategy. Therefore, for the bidding price: Value of the bid= Value of (stage 1+2+3)-cost of PBB- cost of Polisur The cost of stage 3 is already included in the value of stage 3. In question 3, we obtain the Value of (stage 1+2+3) equal to$464. 734 million. Since the Value of the bid>0, then cost of (PBB+ Polisur) < $464. 734million According to the government requirement, Dow could bid PBB for $150 million, then their higher range for Dow’s bid should be $ 314. 734 million ($464. 734million- $150 million).

The History Behind Who Invented HTML

Some of the people who drive the transformation of the internet are well-known: think Bill Gates and Steve Jobs. But those who developed its inner workings are often totally unknown, anonymous, and unsung in an age of hyper-information that they themselves helped to create. Definition of HTML HTML is the authoring language used to create documents on the web. It  is used to define the structure and layout of a  web page, how a page looks, and any special functions. HTML does this by using what are called tags that have attributes. For example, p means a paragraph break. As the viewer of a web page, you dont see HTML; it is hidden from your view. You see only the results. Vannevar Bush Vannevar Bush was an engineer born at the end of the 19th century. By the 1930s he was working on analog computers and in 1945 wrote the article As We May Think, published in the Atlantic Monthly. In it, he describes a machine he called memex, which would store and retrieve information via microfilm. It would consist of screens (monitors), a keyboard, buttons, and levers. The system he discussed in this article is very similar to HTML, and he called the links between various pieces of information associative trails. This article and theory laid the foundation for Tim Berners-Lee and others to invent the World Wide Web, HTML (hypertext markup language), HTTP (HyperText Transfer Protocol), and URLs (Universal Resource Locators) in 1990. Bush died in 1974 before the web existed or the internet became widely known, but his discoveries were seminal. Tim Berners-Lee and HTML Tim Berners-Lee, a scientist and academic, was the primary author of HTML, with the assistance of his colleagues at CERN, an international scientific organization based in Geneva. Berners-Lee invented the World Wide Web in 1989 at CERN. He was named one of Time magazines 100 most important people of the 20th century for this accomplishment. Berners-Lees browser editor was developed in 1991-92. This was a true browser editor for the first version of HTML and ran on a NeXt workstation. Implemented in Objective-C, it, made it easy to create, view, and edit web documents. The first version of HTML was formally published in June 1993.
