Financial Decision - Making - Assignment Example For example, it would not have enough cash to pay creditors the 180,000 due in October, to pay the salaries of staff on time until perhaps January 2007 when a cash inflow of over 1 million is expected, and even to pay its promotional expenses. Note from Table 1 that the 42,000 depreciation, since it is not a cash transaction, is not included in the cash forecast as an outflow from the business during the period. The beginning cash balance includes the 30,000 in cash on 30 September 2006. The beginning and end balances reflect the cash balances at the start and end of the month. If the cash forecast showed a negative amount, how could there be a net profit at the end of the period The answer is that the Profit and Loss (P&L) Report captures the business activity during the period, which is profitable (note the gross and net profit margins of 6.3 and 4.6 percent respectively). The cost of sales includes payments for activities required to generate the sale, to which we add agents' commissions, direct (flight and hotel) and variable costs, administrative overhead, and penalties if booking target volumes of 10,000 holidays are not reached. Two cash transactions are not in the P&L because they refer to past business activities (like paying a 180,000 loan in October 2006 and the 20,000 principal for a previous loan by March 2007) or investments (fixed asset investment of 50,000 in March 2007) that will generate returns over the coming years. Loan repayments and investments in fixed assets are balance sheet transactions and not included in the P&L. The Balance Sheet as in Table 3 before adjustments on 31 March 2007 is as follows: Summary from Table 3 BALANCE SHEET 31-Mar-07 30-Sep-06 Fixed Assets 568,000 560,000 Current Assets (40,000) 30,000 Trade Creditors 0 (180,000) Loans (90,000) (110,000) Total net assets: 438,000 300,000 Share capital 100,000 100,000 Reserves 200,000 200,000 Profit and Loss 138,000 Total shareholders funds: 438,000 300,000 The balance sheet includes figures from Tables 1 and 2 and shows where profits during the 6-month period were used. The negative cash flow of 40,000 from our cash forecast is included as current assets column. This overdraft can be booked as advances from owners that need adjustments (as a current liability or additional equity). We have also added the net

Write a case study on a small group, community, or organization

Write a on a small group, community, or organization - Case Study Example The paper is a comprehensive explanation of the mode of interaction between the American Indians and the rest of Americans. The American Indians are the indigenous inhabitants in the United States of America. They are distinct from the rest of the Americans because they preserve their traditions and are not easily influenced by the modern technology. California in 2000 had the largest population of American Indians. The census report of that year indicated that there were 628,000 American Indians in total. The American Indians are composed of numerous distinct tribes and ethnic groups whose migration happened over thousands of years ago. It involved different groups which are usually referred to as Native Americans or the American Indian. These people crossed over from Asia through a frozen land bridge to the modern day Russia which was by then still part of northern America. They later migrated to Alaska as the ice began to decline thus making them move even further to the southern part. These migrants eventually settled in the modern days United States. Due to their conservative nature, American Indians are regarded as uncivilized by majority of the rest of Americans. But they value their practices since they attach them to identity and unity symbols. Just like all the other communities, they adhere to various social concepts and theories. This is because they have to interact with the rest of the Americans thus making them venerable to internal and external influences. The social concepts and theories apply in various levels and aspects of the American Indians’ lives just like in other social units. Amongst the theories affecting American Indians is the conflict theory. The theory argues that in any society, people do not coexist in pursuit of equilibrium where everybody receives an equal share of resources. It further states that people live competitively with everyone trying to outdo the other with the weakest

What Is Knowledge According To Plato Philosophy Essay

What Is Knowledge According To Plato Philosophy Essay Plato had a strong belief that what we know in this life is recollected knowledge that was obtained in a former life, and that our soul has all the knowledge in this world, and we learn new things by recollecting what the soul already knew in the first place. Plato offers three observations of knowledge and he puts Socrates to reject all three of them. Platos first observation is that true belief is knowledge. Socrates rejects this by stating that when a jury believes the accused to be guilty by just hearing the prosecuting attorneys argument, rather than of any concrete evidence, it cannot be known if a defendant is guilty even if he is guilty. The jurys true belief is therefore not knowledge. The second observation is that knowledge and perception are the same. Socrates rejects this by saying that we can perceive without knowing and we can know without perceiving. For example, we can see and hear a sound without us knowing what or where it is coming from. If we can perceive without knowing, then knowledge cannot be the same as perception. Platos third observation is that true belief along with a logical account is knowledge, but true belief without a logical account is different from knowledge. The only problem with this observation is the word account. All the definitions of the word account are not valid for this argument. These observations are a great example of attacking the insufficient theories of knowledge, but Plato never gives a complete answer on what is the definition of knowledge. Plato preferred truth as the highest value, stating that it could be found through reason and logic in discussion. He called this dialectic. Plato preferred rationality rather than emotional appeal, for the purpose of persuasion, discovery of truth, and as the determinant of action. To Plato, truth was the higher good, and every person should find the truth to guide his or her life. Platos doctrine of recollection says that rather than learning in the common sense, what is actually happening when people are thinking about a problem, and find a solution to that problem, is that they are recollecting things that they already knew. The reason that Plato came up with this theory was because of the learners paradox. The learners paradox is that how can someone learn something if they dont even know what it is. As Meno points out if we dont know what something is then how will we know when we have it? When, for example, we say that we dont know what 946308 divided by 22 is, how can it be that we can find the answer to be 43014? If we dont already know that 946308 / 22 = 43014 then when someone tells us this we should not be able to know that answer is right. Aristotle also believes that knowledge is a form of recollection. He believes that there are universal causes and particular causes, however, unlike Plato; he believes that particulars carry an essence of the form. The four causes, or what makes an object what it is, are its efficient, material, formal, and final causes. The efficient cause is the primary source of the change. The material cause is the material of which it consists. The formal cause is its form. The final cause is its aim or purpose. Using the example of a skyscraper, the efficient cause is the act of building the skyscraper, the material cause is the material used to build it, the formal cause is the blueprint, and the final cause is using the skyscraper as a skyscraper. Everything has these four causes, but substantially changing any of them will cause the skyscraper to lose its skyscraperness. If you know all of a particulars causes, you know its essence. Everything has to have a cause. To truly understand something, we must know its explanation and that it cannot be otherwise. Demonstration must be from things that are true because deducing something from a falsehood would not give understanding of it. Things that are less general and closer to perception are prior relative to us. Things that are more general and further from perception are prior by nature. Demonstrations must be from things that are prior by nature. The premises of demonstrations must give the reason why the conclusion is true. Aristotle defines syllogism as a discourse in which, certain things having been supposed, something different from the things supposed results of necessity because these things are so. One syllogism that he used was: Socrates is a man, All men are mortal, therefore Socrates is mortal. Plato and Aristotles understanding of knowledge are complimentary in that they both believe knowledge is obtained by recollection. Also, they both value truth as the best way to obtain knowledge. What makes it contradictory is that Aristotle goes deeper into the subject of knowledge by stating that particulars have to carry an essence of the form and gives four causes that aid in finding the essence. Therefore, their understanding of knowledge is both complimentary and contradictory. I think we have abandoned the dialectical and demonstrative methods to a certain extent, but not completely. Most classes teach in the way that sophists teach, by just giving us the facts. An example could be my college algebra class, that teaches me how to do a problem but it doesnt tell me why it is like that. But then we have other classes, for example Mr. Hindmans classes, that do use those 2 methods. I think we need to incorporate these valuable methods more into our public school systems and it might help in raising grades up.

Kilwa Kisiwani Medieval Trade Center of Eastern Africa

Kilwa Kisiwani (also known as Kilwa or Quiloa in Portuguese) is the best known of about 35 medieval trading communities located along the Swahili Coast of Africa. Kilwa lies on an island off the coast of Tanzania and north of Madagascar, and archaeological and historical evidence shows that the Swahili Coast sites conducted an active trade between interior Africa and the Indian Ocean during the 11th through 16th centuries CE. Key Takeaways: Kilwa Kisiwani Kilwa Kisiwani was a regional center of the medieval trading civilization located along the Swahili Coast of Africa.Between the 12th and 15th centuries CE, it was a principal port of international trade in the Indian Ocean.  Kilwas permanent architecture included maritime causeways and ports, mosques, and the uniquely Swahili warehouse/meeting place/status symbol called stonehouses.  Kilwa was visited by the Arab traveler Ibn Battuta in 1331, who stayed at the sultans palace.   In its heyday, Kilwa was one of the principal ports of trade on the Indian Ocean, trading gold, ivory, iron, and slaves from interior Africa including the Mwene Mutabe societies south of the Zambezi River. Imported goods included cloth and jewelry from India, and porcelain and glass beads from China. The archaeological excavations at Kilwa recovered the most Chinese goods of any Swahili town, including a profusion of Chinese coins. The first gold coins struck south of the Sahara after the decline at Aksum were minted at Kilwa, presumably for facilitating international trade. One of them was found at the Mwene Mutabe site of Great Zimbabwe. Kilwa History The earliest substantial occupation at Kilwa Kisiwani dates to the 7th/8th centuries CE when the town was made up of rectangular wooden or wattle and daub dwellings and small iron smelting operations. Imported wares from the Mediterranean were identified among the archaeological levels dated to this period, indicating that Kilwa was already tied into the international trade at this time, albeit in a relatively small way. Evidence shows that the people living at Kilwa and the other towns were involved in some trade, localized fishing, and boat use. Historical documents such as the Kilwa Chronicle report that the city began to thrive under the founding Shirazi dynasty of sultans. Growth of Kilwa Sunken Courtyard of Husuni Kubwa, Kilwa Kisiwani. Stephanie Wynne-Jones/Jeffrey Fleisher, 2011 Kilwas growth and development around the beginning of the second millennium CE was part and parcel of the Swahili coast societies becoming a truly maritime economy. Starting in the 11th century, the residents began deep-sea fishing for sharks and tuna, and slowly widened their connection to international trade with long voyages and marine architecture for facilitating ship traffic. The earliest stone structures were built as early as 1000 CE, and soon the town covered as much as 1 square kilometer (about 247 acres). The first substantial building at Kilwa was the Great Mosque, built in the 11th century from coral quarried off the coast, and later greatly expanded. More monumental structures followed into the fourteenth century such as the Palace of Husuni Kubwa. Kilwa rose to its first importance as a major trade center about 1200 CE under the rule of the Shirazi sultan Ali ibn al-Hasan. About 1300, the Mahdali dynasty took over control of Kilwa, and a building program reached its peak in the 1320s during the reign of Al-Hassan ibn Sulaiman. Building Construction Bathing Pool at Husuni Kubwa, Kilwa Kisiwani. Stephanie Wynne-Jones/Jeffrey Fleisher, 2011 The constructions built at Kilwa beginning in the 11th century CE were masterpieces built of different types of coral mortared with lime. These buildings included stone houses, mosques, warehouses, palaces, and causeways—maritime architecture that facilitated docking ships. Many of these buildings still stand, a testament to their architectural soundness, including the Great Mosque (11th century), the Palace of Husuni Kubwa and the adjacent enclosure known as the Husuni Ndogo, both dated to the early 14th century. The basic block work of these buildings was made of fossil coral limestone; for more intricate work, the architects carved and shaped porites, a fine-grained coral cut from the living reef. Ground and burnt limestone, living corals, or mollusk shell were mixed with water to be used as whitewash or white pigment; and combined with sand or earth to make a mortar. The lime was burned in pits using mangrove wood until it produced calcined lumps, then it was processed into damp putty and left to ripen for six months, letting the rain and groundwater dissolve the residual salts. Lime from the pits was likely also part of the trade system: Kilwa island has an abundance of marine resources, particularly reef coral. Layout of the Town Aerial view of stone ruins at Kilwa Kisiwani, Swahili coast, Tanzania.   Paul Joynson Hicks / AWL Images / Getty Images Visitors today at Kilwa Kisiwani find that the town includes two distinct and separate areas: a cluster of tombs and monuments including the Great Mosque on the northeast part of the island, and an urban area with coral-built domestic structures, including the House of the Mosque and the House of the Portico on the northern part. Also in the urban area are several cemetery areas, and the Gereza, a fortress built by the Portuguese in 1505. Geophysical survey conducted in 2012 revealed that what appears to be an empty space between the two areas was at one time filled with lots of other structures, including domestic and monumental structures. The foundation and building stones of those monuments were likely used to enhance the monuments that are visible today. Causeways As early as the 11th century, an extensive causeway system was constructed in the Kilwa archipelago to support the shipping trade. The causeways primarily act as a warning to sailors, marking the highest crest of the reef. They were and are also used as walkways allowing fishermen, shell-gatherers, and lime-makers to safely cross the lagoon to the reef flat. The sea-bed at the reef crest harbors moray eels, cone shells, sea urchins, and sharp reef coral. The causeways lie approximately perpendicular to the shoreline and are built of uncemented reef coral, varying in length up to 650 feet (200 meters) and in width between 23–40 ft (7–12 m). Landward causeways taper out and end in a rounded shape; seaward ones widen into a circular platform. Mangroves commonly grow along their margins ​and act as a navigational aid when the high tide covers the causeways. East African vessels that made their way successfully across the reefs had shallow drafts (.6 m or 2 ft) and sewn hulls, making them more pliant and able to cross reefs, ride ashore in heavy surf, and withstand the shock of landing on the east coast sandy beaches. Kilwa and Ibn Battuta The famous Moroccan trader Ibn Battuta visited Kilwa in 1331 during the Mahdali dynasty, when he stayed at the court of al-Hasan ibn Sulaiman Abul-Mawahib (ruled 1310–1333). It was during this period that the major architectural constructions were built, including elaborations of the Great Mosque and the construction of the palace complex of Husuni Kubwa and the market of Husuni Ndogo. Kilwa Kisiwani (Quiloa) - undated Portugueuse map, published in Civitates Orbis Terrarum in 1572. Hebrew University of Jerusalem The prosperity of the port city remained intact until the last decades of the 14th century when turmoil over the ravages of the Black Death took its toll on international trade. By the early decades of the 15th century, new stone houses and mosques were being built up in Kilwa. In 1500, Portuguese explorer Pedro Alvares Cabral visited Kilwa  and reported seeing houses made of coral stone, including the rulers 100-room palace, of Islamic Middle Eastern design. The dominance of the Swahili coastal towns over maritime trade ended with the arrival of the Portuguese, who reoriented international trade towards western Europe and the Mediterranean. Archaeological Studies at Kilwa Archaeologists became interested in Kilwa because of two 16th century histories about the site, including the Kilwa Chronicle. Excavators in the 1950s included James Kirkman and Neville Chittick, from the British Institute in Eastern Africa. more recent studies have been led by Stephanie Wynne-Jones at the University of York and Jeffrey Fleischer at Rice University. Archaeological investigations at the site began in earnest in 1955, and the site and its sister port Songo Mnara were named UNESCO World Heritage site in 1981. Sources Campbell, Gwyn.

They usually dont think about connecting athletics with academics. In reality math, science, and especially physics, tie into every aspect of sports. Sports are a commonality that brings nations together, Soccer, known as football to most of the world, is said to an unspoken language, which unties people from different lands through a passion to play a game. AthleticsRead MoreThe History of Physics Essay1534 Words   |  7 PagesThe History of Physics In order to attempt to trace the origins of the modern science that we now refer to as â€Å"physics,† we must begin with the origin of the term itself. Taken from the Greek word â€Å"physika† meaning growth or nature, physics most obviously began as the intelligent study of the human environment (Webster 393). From superstition and religious practices, the foundation of all other sciences was born. These concepts have subsequently grown into what we regardRead MorePhysics Of The Impossible By. Kaku1468 Words   |  6 PagesThe book â€Å"Physics of the Impossible† was written by Japanese American theoretical physicist Michio Kaku. Kaku generally writes books about physics or physics related topics. Among his three New Work Times best seller, Physics of Impossible is one in which Kaku utilizes discourse of theoretical advancements to acquaint themes of basic material science with the reader. In this book, Kaku represents physics in various ways so that the reader understands the significance of physics and implement in his/herRead MorePhysics by Aristotle Essay547 Words   |  3 PagesPhysics by Aristotle Aristotle begins by describing the meaning of the words â€Å"nature† and â€Å"natural.† He identifies the meaning of each, and also explains some common phrases which include each of the words. He says all natural things have a principle of motion and of stationariness. He also says that natural things are composed of stone, earth, or a mixture of the two. According to him, artificial products do not possess the source of their own production. For example, the natureRead MoreThe Physics Of Albert Einstein1284 Words   |  6 Pageswould also think that one who drops out of high school may not go anywhere in life. Einstein won a Nobel Prize in Physics, a Gold Medal of The Royal Astronomical Society, and many other awards. Even if Einstein never even finished high school, his creation of the equation E = mc2, theory of relativity, and theory of light led the way to him becoming known as the father of modern physics. Albert Einstein was Born in Ulm, Wà ¼rttemberg, Germany in 1879. He was the son of Hermann Einstein, a salesman andRead MoreReflection On Physics1032 Words   |  5 Pageshave always loved physics. I didn’t. In fact, I hated physics in the 9th and 10th grades, not because I didn’t like doing science or was bad at mathematics, but because I was unable to understand the equations, that appeared to come from nowhere. According to my physics teacher, both of the equations for a vertically thrown ball y = 1/2gt 2 + v 0 t and y = −1/2gt 2 + v 0 t were correct, which didn’t make much sense to me because the signs were different! However, my view on physics changed dramaticallyRead MoreEssay on A Century of Physics3573 Words   |  15 PagesA Century of Physics By the end of the nineteenth century after more than two thousand years of intellectual struggle that began with the Greek philosophers, physical scientists had reason to believe that they were beginning to understand the universe. Their theories of matter and energy, of electricity and magnetism, of heat and sound and light were confirmed in laboratories throughout the world with increasing precision. Experimentation was the method and mathematics the language of aRead MorePhysics Of String Theory Of Physics1543 Words   |  7 Pagesnumber of excitation modes - that are the elementary particles observed. the strings have tension of 1/(2 p a’) strings are approximately the planck length (smallest possible size of black hole) 10^(-33) cm A quantum Theory of Gravity is needed In physics there are two main central theories. The first is Einstein’s theories of relativity. The second is quantum mechanics. Einstein’s theories of relativity describe gravity but does not include quantum effects. Quantum mechanics describes the universeRead MoreEssay about Physics in Cartoons555 Words   |  3 PagesPhysics in Cartoons The cartoon that was analyzed by our group was the Disney movie The Emperors New Groove. This movie is very entertaining and comical, however when a closer look is taken at the use (or lack thereof) of Physics Laws, many errors can be found. The following are four examples of situations in The Emperors New Groove where the laws of physics were over looked and ignored in the creation of the scene. #1 (19:05-19:48) After Emperor Kusko is
