Chemistry Review of pOH Calculations

Chemistry Review of pOH Calculations Sometimes you are asked to calculate pOH rather than pH. Heres a review of the pOH definition and an example calculation. Acids, Bases, pH and pOH There are several ways to define acids and bases, but pH and pOH refer to hydrogen ion concentration and hydroxide ion concentration, respectively. The p in pH and pOH stands for negative logarithm of and is used to make it easier to work with extremely large or small values.  pH and pOH are only meaningful when applied to aqueous (water-based) solutions. When water dissociates it yields a hydrogen ion and a hydroxide. H2O ⇆ H OH- When calculating pOH, remember that [] refers to molarity, M.

Now press log. Remember your answer is the negative value (-) of this number.pOH - (-4.37)pOH 4.37 Understand Why pH + pOH = 14 Water, whether its on its own or part of an aqueous solution, undergoes self-ionization which can be represented by the equation: 2 H2O ⇆ H3O OH- Equilibrium forms between the unionized water and the hydronium (H3O) and hydroxide (OH-) ions. The expression for the equilibrium constant Kw is: Kw [H3O][OH-] Strictly speaking, this relationship is only valid for aqueous solutions at 25 °C because that is when the value of Kw is 1 x 10-14. If you take the log of both side of the equation: log  (1 x 10-14)  Ã‚  log  [H3O]  Ã‚  log  [OH-] (Remember, when numbers are multiplied, their logs are added.) log  (1 x 10-14)  Ã‚  -  14-  14  Ã‚  log[H3O]  Ã‚  log  [OH-] Multiplying both sides of the equation by -1: 14  Ã‚  -  log  [H3O]  -  log  [OH-] pH is defined as  -  log  [H3O] and pOH is defined as -log  [OH-], so the relation becomes: 14 pH - (-pOH)14 pH pOH

In order to reduce Cost, Company can try for new techniques for marketing as well as sales, but while doing so customer reaction to these changes should not be ignored. If any changes are done without analyzing market reaction it may result in crisis. â€Å"Gourmet Direct is a web-based New Zealand company delivering high quality gourmet products to the food industry and the public. The company experienced a crisis of customer confidence and loss of business when it attempted to rationalize its product lines by changing from a pick and mix ordering system to having only a set number of packs available for sale. This change was designed to achieve cost savings through a reduced inventory and reduced distribution expenses, but had a further consequence of reducing product availability and ordering flexibility for customers. Customers immediately expressed their displeasure, and the company’s sales plunged dramatically in the year that the decision was implemented. With the bulk of the companys sales usually occurring over the Christmas period, December sales almost halved. The following first quarter sales dropped an alarming 76% compared to the same period in the previous year† In this case company changed its sales policies from a pick and mix ordering system to having only a set number of packs available for sale in order to reduce inventory and distribution expenses, But due to this changes customers found less options for selection and faced lack of availability of product. This was the actual reason for customer dislikes and they stopped buying, which finally resulted in reduced sales on company side. Clearly this is mistake from company’s side. Company should not have implemented changes suddenly all over market at the same time.

Read chapter Nighn 9 and answer the questions - Essay Example These musicians were responsible for promoting Nueva Cancion in support of an intensive leftist protest that expressed distaste for a totalitarian and capitalist regime as well as imperialism which occurred to corrupt the nation’s cultural identity at that period. As a turning point in the history of the movement, the presidential campaign of Salvador Allende in 1970 became sensationalized especially as it managed to convey the leader’s strong Marxist convictions through an open election in which the Nueva cancioneros contributed rhythms that thematically coincided with Allende’s communist principles. At the time, the government may be perceived as a government of revolution which responded in utter agreement to the combined political ideals and musical creativity of the radical artists. The short-lived administration and the forerunning characters of the Nueva Cancion were of a single heart and passion in being pro-people so that their joint forces, as a whole, were accounted for as highly significant in Latin American history, having influenced the world with songs that communicate advocacies for human rights, anti-oppression, ethnicity, liberation, anti-poverty, and non-dictatorial martial rule. As an unfortunate consequence, however, the brutish takeover of the powerful military coup some three years later fated Allende and supporters, Victor Jara, and some fellow artists with a tragic end of death. The coup reacted to this extent of employing harsh measures toward Nueva Cancion as the movement had been viewed widely with the ample capacity to move and educate communities and turn them against their unrighteous rulers as vividly evident for instance in the crafts of Jara via lyrical substance of the pieces â€Å"Venceremos† and â€Å"El aparecido†. (2) What is a wawa velorio? Why is it a celebration? What takes place at this ceremony? (What types of activities and what type of music.) (1/3-page) Basically, the term ‘ wawa velorio’ pertains to a child’s wake that is presented in a ritualistic manner and in particular, J.T. Titon describes it as an all-night affair for the wake of the deceased Quichua child. To illustrate the chief ground behind the rationale of its celebration, Titon states that â€Å"The death of young children in Ecuador and throughout Latin America is a daily tragedy, one that through its very frequency ironically serves to preserve dozens of unique regional traditions of genre, instrument, and dance.† Based on this, a thoughtful reflection may be inclined to figure that the sadness of such regular tragedy must have been too much to bear that families and the rest of the community prefer to celebrate with music and dynamic colourful activities rather than mourn over their grave loss of tender-aged loved ones. Apparently it makes sense, for when Latinos are gathered as such, they may be alleviated of a huge portion of burden as singing and dancing could fun ction as a tribute to the dead and a natural yet sacred acknowledgment of mortality and life’s severe misfortunes. During the ‘wawa velorio’ event, according to Titon, a harpist and a golpeador or wake singer are hired to play vacacion – a music sharply rendered with percussion instruments and sanjuan, respectively. While vacacion is purely instrumental and is solely played by the

Research Process and Terminology Paper Essay The aim of this paper is to address the linkage between foreign direct investment (FDI) flows and the number of natural disasters. By using the data of 94 countries in the period of 1984 to 2004 and applying a variety of empirical tests, the result appears that natural hazards have significantly negative effects on FDI of countries. A. Economic Effects of Natural Disasters and The Determinants of Foreign Direct Investment Economic Effects of Natural Disasters There are three patterns that concern with the economic effects of natural hazard. The first two strands concentrates on the primary or short-term effects and long-term effects of hazards on economy. While the short-term effect strand achieves abundant evidences of negative disasters’ impacts on GDP, the long-term effect strand cannot reach a clear conclusion. The third strand focuses on the capacity to mitigate the destructive effects of natural risks. A brief conclusion is that the negative impacts of risks can be diminished by country’s institutions. Determinant of Foreign Direct Investment There are three types of foreign direct investment, namely: (1) Operating new (2) Moving an existing (3) Moving a part of existing The first type is considered as location decision and categorized in pull factor, the latter two types are relocation decision and belong to push factor. Following this logic, propositional pull factors to put in models are the level of openness and the size of the economy. Obviously, the push  factor in models is natural risks. Other determinants which are mainly focused are institutions, such as government infrastructure, political freedom, corruption, etc. B. Data and Methods The data for analyzing impacts of natural disasters on FDI flows are taken from the EMDAT, which provides by the institution Center for Research on the Epidemiology of Disasters (CRED) and World Bank. Some observations were dropped because of missing data, the data which is used in this research contains an unbalance panel with 1,822 country-year observations from 94 countries (29 in Africa, 17 in Asia, 22 in Europe and 26 in Americas) in the period 1984-2004. Table 2 presents descriptions of dependent and independent variables. (TABLE 2) At this point, it is important to look again at two primary variables which devoted to results of empirical tests. The first key variable is FDI, which is measured by the total net inflows of foreign direct investment as a percentage of GDP. FDI is the dependent variable in all models. The second key variable relates to natural hazards. Since both recent and longerterm risks have its impacts on investors, the authors deliver four variables that are concerned with the number of natural risks happening in four time period: Total events in the prior year, total events in the prior 5 years, total events in the prior 10 years, total events in the prior 25 years. Table 3 shows the correlations between FDI/GDP and each of four variables referring to the measures of natural risks. (TABLE 3) It is undoubtedly true that both the counted measure as number of natural hazards and the monetary measure as the estimation of â€Å"dollar value of damages† affect decision makers. While it can be argue that result as the dollar amount of damages may have substantial influence on investors’ decisions, it is obvious that estimating the consequence of natural disasters is complex and not as accurate as â€Å"counts of disasters†. For this  reason, models will mainly focus on counts of disasters. Moreover, the research emphasizes on five types of natural hazards that severely devastate infrastructures, physical capital and labor forces. As such, these five types are earthquakes, floods, volcanoes, landslide and windstorms (include hurricanes). The following two variables which refer to the degree of openness and incentive in trade and investment are Trade and Investment. The former is taken from World Bank’s 2008 World Development Indicators and the latter is provided by Political Risk Services Group, assembled by the IRIS Center at the University of Maryland. Regarding to a country’s reliability for trade and investment, the investment variable is the estimation of three factors: contract viability/risk of exportation, repatriation of profits and delay in payments. These three factors are rank from 0 to 12 and the higher value illustrates the higher risk in investment. The final three variables in the base model are Inflation, Gov. stability and Rule of law. The Inflation variable is the inflation level of each country in a particular year and taken from 2008 World Development Indicators. The other two variables are collected from the International Country Risk Guide, with reflecting the level of stability of government and adhesion to the rule of law. The higher value implies the better environment for investors. Those variables contribute to the base model as this form: FDIit = ÃŽ ±0 + ÃŽ ±1Total events in the prior # yearsit + ÃŽ ±2GDP per capitait + ÃŽ ±3GDP growthit + ÃŽ ±4Tradeit + ÃŽ ±5Investmentit + ÃŽ ±6Inflation + ÃŽ ±7Gov. stabilityit + ÃŽ ±8Rule of lawit + ÃŽ ³i + ÃŽ ³t + ÃŽ µit This research also employs ÃŽ ³i as country fixed effects over time and ÃŽ ³t as year fixed effects for all countries. C. Results and Their Implications The below table indicates the linkage between foreign direct investment and natural disasters by applying the base model. It can be seen from Table 4 that all four natural hazard variables have significantly negative effects on FDI in each of models. Moreover, there is a decline trend in coefficients of disaster variables when measuring in Total events in the prior 1 year to Total events in the prior 25 years, which suggests that relatively recent risks have more significant influence than long term risks on investors’ decisions. The next two variables, which are GDP per capita and GDP growth, are positive as expected and significant. However, although both Trade and Investment variables have positive effects on FDI, only Trade is significant. The Inflation variable is negative and significant in all four models. Only Gov. stability variable has unexpected side and both Gov. stability and Rule of law are not significant in all models. The authors also employ the empirical tests to find out different effects of five particular types of disasters. The result is presented in Table 5. The outcome demonstrates that all other non-disaster variables have the same reaction and all damage variables are negative in side. However, Windstorms is significant in all three cases, Volcanoes is significant in two cases while Landslides, Earthquake and Floods are significant in only one case. Hence, there is evidence to support the view that each type of hazards has its effects on FDI, the clearest evidence is found on Windstorms. Regardless the inaccurate in estimation of dollar value of damages, the research generates the final test by using the base model with â€Å"dollar value of damages† in place of â€Å"counts of disasters†. The result is displayed in Table 6. Similarly with the above case, all non-disaster variables have the same result as the base model case. Though disaster variables are negative and significant in all case, they do not decline from recent to older events. A draw conclusion may be policy makers equally focus on relative recent and longer-term risks or maybe there is error in data. D. Conclusion To sum up briefly, there are four important conclusions. First and foremost, natural disasters have significant and negative effect on foreign direct  investment. Second, there are some evidences to support the view that decisions of foreign investors are deeper affected by relative recent events in comparing to longer-term events. Third, different types of natural hazards are considered to have different impacts on foreign direct investment, the most severe impact is found on windstorms. Finally, regardless the intricacy and inaccuracy in monetary measuring the value of damages, the model which focuses on dollar value of damages also addresses the same result with the base model: natural disasters discourage foreign direct investment.

Imagery and Themes in the Epic of Gilgamesh Essay -- Epic Gilgamesh es

Historical Context - Imagery and Themes Rosenberg notes that Gilgamesh is probably the world's first human hero in literature (27). The Epic of Gilgamesh is based on the life of a probably real Sumerian king named Gilgamesh, who ruled about 2600 B.C.E. We learned of the Gilgamesh myth when several clay tablets written in cuneiform were discovered beginning in 1845 during the excavation of Nineveh (26). We get our most complete version of Gilgamesh from the hands of an Akkadian priest, Sin-liqui-unninni. It is unknown how much of the tale is the invention of Sin-liqui-unninni, and how much is the original tale. The flood story, which appears in the Sin-liqui-unninni version, is probably based on an actual flood that occurred in Mesopotamia around 2900 B.C.E. (26). The Sumerian culture influenced the entire Near East (Swisher 13). The success of their culture was dependent on the agricultural viability of the area. Every year there were floods which provided rich silt for successful farming that encouraged the people to stay in the same area year after year instead of migrating to find new areas for crops (19). There are indications that the Sumerians were composed of two different peoples which mingled in the same area. The Semites are believed to have mixed with the Highlanders. The Semites were patriarchal hunters and more warlike than the Highlanders. The Highlanders were matriarchal and peaceful. Swisher suggests that there is evidence of both social groups and that the combination of the two led to changes in the perception of the roles of the gods and goddess as well as the men and women (21). Sumer was originally small groups of people that eventually grew to form cities. As a country it included 13 ... ...der to receive eternal life. The apparent belief in an afterlife which is indicated by the burial with useful objects may show that eternal life is achieved after physical death. The Flood - recounted by Utanapishtim is representative of the purification of human life by the gods. Their transgressions are swept away (with most of the population) and they are reborn into a fresh, new world and relationship with the gods. Ark - the symbol of the gods' love of the humans and their interest in preserving the human race. We also identified five themes in the Epic of Gilgamesh: Conflict between chaos and order, represented by nature and civilization; Man's quest for immortality and knowledge; Dealing with loss; Male bonding/brotherhood; Heroism (man's victory over nature).

Forms of Business Organization Essay

The study of business organization is a study of complexity: as each business is different, each form of business organization is also unique. From a local hot-dog vendor to a trucking company, from a restaurant to a multinational, each business has different legal, moral and ethical concerns, and there is no â€Å"one-size-fits-all† approach to determine how a business should best be organized. Take the first two businesses, the hot-dog vendor and the trucking company, as an example: assume that each business is operated by a single individual. While one may argue that the proper form of organization for each would be a sole proprietorship, that would not be the case: the hot-dog vendor could clearly be operated as a sole proprietorship, but not the trucking company. Because of the nature of the trucking business, limiting the liability of the principals is vital: thus, the best form of organization for the trucking company would most likely be an LLC (limited liability company). There are six main forms of business organization, and each has very distinct advantages and disadvantages: some work best for small enterprises, some are better when outside vendors are involved, some are more suitable for larger companies†¦ indeed, there are many variables to consider when determining the organization of a business. Sole Proprietorship The most common form of business organization is called a sole proprietorship. The most common way to organize a business, Entrepreneur.com describes it thusly: The sole proprietorship is a popular business form due to its simplicity, ease of setup, and nominal cost. It is the easiest form of business to setup: again, according to Entrepreneur, a sole proprietor need only register his or her name and secure local licenses, and the sole proprietor is ready for business. As the business is not incorporated, all assets and liabilities relating to this form of business are under the control of the individual who started the business; thus, the business owner assumes full liability in the event of a legal judgment. In addition, as there is no legal protection for the business (it being indistinct from the owner), it is entirely possible for a sole proprietor to see their business liquidated as the result of a lawsuit. The owner has complete control of this form of business: no control has to be granted to anyone else. An advantage to this is that they retain all profits: nothing has to be shared with anyone else, and their return on investment is 100%. Income taxes are easy to calculate: a sole proprietor need only declare their business income on their individual tax form. Because of this, there is no real additional workload or burden to the owner unless they choose to do business under a name other than their own, in which case they would be required to register their business name with the particular jurisdiction they reside in. The location of the business only matters if an individual wants to avoid a particular jurisdiction’s individual income taxes (corporate taxes are not filed for this form of business): for instance, some states do not charge income tax. No separate legal entities have to be formed if the business changes location: the business is connected to the individual and the business exists as long as the individual chooses to operate it. This form of business has a limited longevity: according to Entrepreneur, sole proprietorships rarely survive the death or incapacity of their owners and so do not retain value. They generally dissolve upon the death of the principal and so cannot be passed on to heirs or others. General Partnership According to the Small Business Administration, a general partnership is a business owned by two or more people, with the business partners equally sharing the responsibilities of the business. Like a sole proprietorship, the individual owners of the business assume unlimited liability: it is possible for the business owners to be liquidated due to a legal judgment or the failure of the business. Additionally, because the actions of one of the partners are binding on all the others, the entire partnership can prosper or suffer due to the actions of a single member (The Free Dictionary). Also like a sole proprietorship, a general partnership is, as Quick MBA puts it, a â€Å"?†¦tax reporting entity, not a tax paying entity.†? In other words, the partnership is only a method of business organization; it is not a legal entity for tax purposes, and the individual business owners assume tax liability separately. The longevity of a partnership is potentially greater than a sole proprietorship: for example, since there are one or more other partners, the death of one member does not mean the end of the business since their share can be passed along to heirs. Control in a general partnership is shared equally: since there is no one owner, all decisions (and their effects) are shared equally. Profits are divided among the partners: while the liabilities are shared, the profits can sometimes be divided unequally upon agreement. This can affect return on investment: since it is possible to invest in a partnership without being an active member, it is possible to lose money on an investment if the active principals make decisions that affect the business negatively. As with a sole proprietorship, location is not a real concern with a general partnership: since the principals, not the business, are the ones responsible for the tax liability, the decision on where to locate has little to do with corporate tax liability. Like a sole proprietorship, the only real regulatory burden is if the general partnership chooses to do business under a name under their own: the name would have to be registered. Limited Partnership A limited partnership is similar to a general partnership. Quick MBA describes a limited partnership as a partnership with two or more partners, with one or more general and limited partners. The biggest difference is that a limited partner does not assume unlimited liability: their liability is limited to the amount of their investment. Also, since general partners are held wholly liable, they are often LLC’s (limited liability corporations) rather than individuals. Like a general partnership, income and income taxes are generally divided among the principals, but a limited partnership has to meet certain criteria to enjoy this right: otherwise it is taxed as a corporation. The rules of continuity in this sort of organization are different from those of a general partnership. The continuity of the organization is assured: while a general partnership generally must dissolve if a partner leaves, shares of a limited partnership can be created and can be transferred, bought or sold, though principals in the organization have the right to first bid (Quick MBA). Control of a limited partnership rests in the hands of the general partners: because they have management control, they do not have to grant control to anyone else in the organization: in fact, limited partners lose their status if they take a managing role in the business. Like the general partnership, the profits are shared between the partners: because limited partners are investors in the company, they often receive a greater share of the profits because of their financial contribution. Location concerns as the same as in a general partnership. Concerns of convenience or burden are also the same unless the partnership acts as a corporation, in which case corporate regulations must be followed. C-corporation According to Wikipedia, C-corporations are corporations that are taxed separately from their owners. In the United States, corporations are considered â€Å"people† for tax and liability purposes: in this form of business organization, C-corps are individual â€Å"persons† considered separate from shareholders and directors (Expertlaw.com). Because of this, the liability of the shareholders (note that in a corporation, shareholders are the owners of the organization) is limited: shareholders are protected from assuming the burdens of the corporation if it is unable to meet its obligations. Income taxes for the c-corp are calculated at the corporate tax rate: sometimes this rate is lower than the income tax rate of the shareholder’s, but oftentimes it proves to be much higher. Dividends are subject to the capital gains tax of 15%, then subject to the income tax rate of the shareholder; thus, the profits have been taxed twice. The longevity of this form of organization is perpetual: because the company is owned by shareholders, even if the owner leaves the company can continue to exist (The Company Corporation). Control of a C-Corp rests in the hands of shareholders: the owner has control only so far as their share of the company allows. Shareholders generally elect a board of directors to act on their behalf. As with control of the company, profits belong to the owner only in proportion to the amount of stock in the company they possess. Compared to the forms of organization discussed previously, location has a great deal to do with how and where a C-Corp does business. Phrases such as â€Å"Nevada corporation† or â€Å"Delaware corporation† have entered popular usage: they refer to corporations incorporated in these states solely due to their business-friendly incorporation laws (i.e. easy incorporation, no need to elect a board or issue stock, etc). Because corporations are regulated by the states, often times businesses will be incorporated in a state other than the one they do business in. This form of business organization comes with more of a burden on the business owner than the previous three: the states and the federal government heavily regulate corporations, these forms of business are more expensive to establish, and the paperwork burden is much greater. S-Corporation S- and C-corps are very similar, but there are some differences. Like a C-corporation, shareholders are not individually liable for business debts and resopnsibilities (BizFilings). Also, the are similar when it comes to the longevity, profit retention, and location requirements of an S- or C-corporation. The two biggest differences involve the control of the company and the income tax burden. In a C-corp, an unlimited number of shareholders are allowed, and they can be domestic or foreign nationals; however, a S-corp only allows 100 shareholders, and they must be US nationals. When it comes to income taxes, C-corps file as a corporation and corporate taxes are paid; however, an S-corp is a â€Å"pass-through†, meaning that taxes on earnings are filed and paid by the individual shareholders. Limited Liability Company A limited liability company, according to Wikipedia, is a form of organization that combines the features of a partnership with those of a corporation. Like a corporation, liability is limited: the personal assets of business owners are generally shielded from those of the company. Income taxes are treated differently from the other forms of organization: an LLC can elect how it wants to be treated for tax purposes. LLC’s are, like partnerships and sole proprietorships, pass-through entities: taxes are generally not calculated on the firm as a whole, but on the earnings reported on the individual tax returns of the principals. The continuity of the organization depends on how it is organized: if it is organized as a partnership, the longevity is assured. The principals of the company have control of the company: if one person alone is in charge, the LLC can operate as a sole proprietorship for control purposes. Profits are divided among the individual owners: a single owner retains control of all profits, but partners divide the proceeds. The location of an LLC can be important: for instance, in Washington D.C., LLC’s are not allowed to pass-through income for tax purposes, and some states assess levies for the privilege of operating as an LLC (Wikipedia). Compared to corporations, LLC’s have only a minor paperwork burden: though some states regulate them more than others, there is often little more to do aside from filing the standard sole proprietorship/partnership paperwork. Different companies call for different forms of organization: what may work for the sole owner of a shop may not be successful for a large organization. Oftentimes the greater paperwork or regulatory burden imposed on corporations is offset by the advantages of incorporation; sometimes an LLC or partnership may work better. Before deciding on the form of business organization, a prospective business owner will do well to perform a thoughtful analysis to determine which approach will suit their business model.
