Acheulean Tradition

Acheulean Tradition The Acheulean (sometimes spelled Acheulian) is a stone tool techno-complex that emerged in East Africa during the Lower Paleolithic about 1.76 million years ago (abbreviated mya), and persisted until 300,000-200,000 years ago (300-200 ka), although in some places it continued as recently as 100 ka. The humans who produced the Acheulean stone tool industry were members of the species Homo erectus and H. heidelbergensis. During this period, Homo erectus left Africa through the Levantine Corridor and traveled into Eurasia and eventually Asia and Europe, bringing the technology with them. The Acheulean was preceded by the Oldowan in Africa and parts of Eurasia, and it was followed by the Mousterian Middle Paleolithic in western Eurasia and the Middle Stone Age in Africa. The Acheulean was named after the Acheul site, a Lower Paleolithic site on the Somme River in France. Acheul was discovered in the mid-19th century. Stone Tool Technology The defining artifact for the Acheulean tradition is the Acheulean handaxe, but the toolkit also included other formal and informal tools. Those tools included flakes, flake tools and cores; elongated tools (or bifaces) such as cleavers and picks (sometimes called trihedrals for their triangular cross-sections); and spheroids or bolas, roughly rounded sedimentary limestone rocks used as a percussion tool. Other percussion devices on Acheulean sites are hammerstones and anvils. Acheulean tools demonstrate a significant technological advance over the earlier Oldowan; an advance thought to parallel a cognitive and adaptive increase in brain power. The Acheulean tradition is broadly correlated with the emergence of H. erectus, although the dating for this event is /- 200,000 years, so the association of the evolution of  H. erectus with the Acheulean toolkit is a bit of a controversy. Besides flint-knapping, the Acheulean hominin was cracking nuts, working wood, and butchering carcasses with these tools. She had the ability to purposely create large flakes (10 centimeters [4 inches] in length), and reproduce standard tool shapes. Timing of the Acheulean Pioneer paleontologist Mary Leakey established the Acheuleans position in time at Olduvai Gorge in Tanzania, where she found Acheulean tools stratified above the older Oldowan. Since those discoveries, hundreds of thousands of Acheulean handaxes have been found throughout Africa, Europe, and Asia, spanning several million square kilometers, in multiple ecological regions, and accounting for at least one hundred thousand generations of people. The Acheulean is the oldest and longest-lasting stone tool technology in the worlds history, accounting for more than half of all recorded tool-making. Scholars have identified technological improvements along the way, and although they agree that there were changes and developments during this huge chunk of time, there are no widely-accepted names for the periods of technology change, except in the Levant. Further, since the technology is so wide-spread, local and regional changes occurred differently at different times. Chronology The following is compiled from several different sources: see the bibliography below for further information. 1.76-1.6 mya: Early Acheulean. Sites: Gona (1.6 mya), Kokiselei (1.75), Konso (1.75), FLK West, Koobi Fora, West Turkana, Sterkfontein, Bouri, all in eastern or southern Africa. Tool assemblages are dominated by large picks and thick bifaces/unifaces made on large flake blanks.1.6-1.2 mya: Sterkfontein, Konso Gardula; refinement of handaxe shape begins, advanced shaping of handaxes seen at Konso, Melka Kunture Gombore II by 850 ka.1.5 mya outside Africa: Ubeidiya in the Jordan Rift Valley of Israel, bifacial tools, including picks and handaxes, which account for over 20% of the tools. Additional tools are chopping tools, choppers and flake tools but no cleavers. Raw source material varies by tool: bifacial tools on basalt, chopping tools and flake tools on flint; spheroids in limestone1.5-1.4 in Africa: Peninj, Olduvai, Gadeb Garba. Massive production of large, shaped tools, high-quality raw materials, flake blanks, cleavers1.0 mya-700 ka: known as Large Flake Acheulian in some place s: Gesher Benot Yaaqov (780-660 ka Israel); Atapuerca, Baranc de la Boella (1 mya), Porto Maior, El Sotillo (all in Spain); Ternifine (Morocco). Numerous bifacial tools, handaxes, and cleavers make up the site assemblages; large flakes (exceeding 10 cm in maximal dimension) were used to produce handaxes. Basalt was the  preferred source for cutting materials, and true flake cleavers were the most common tool. 700-250 ka: Late Acheulean: Venosa Notarchirico (700-600 ka, Italy); La Noira (France, 700,000), Caune de lArago (690-90 ka, France), Pakefield (UK 700 ka), Boxgrove (UK, 500 ka). There are hundreds of sites dated to the Late Acheulean with many thousands of handaxes, found in harsh deserts to Mediterranean landscapes, and some of the sites have hundreds or thousands of handaxes. Cleavers are almost absent and large flake production no longer used as a primary technology for handaxes, which are at the end made with early Levallois techniquesMousterian: replaced all LP industries beginning around 250,000, widely associated with Neanderthals and later with the spread of Early Modern Humans.

Answers to Questions About Abbreviations

Answers to Questions About Abbreviations Answers to Questions About Abbreviations Answers to Questions About Abbreviations By Mark Nichol Responses to some reader queries about abbreviation issues follow. 1. Which is the preferred abbreviation for â€Å"United States,† US or U.S.? Both forms are correct, but, in the interests of consistency with the decline of the use of periods in abbreviations, the trend is to use US. (Note that the abbreviation should be used only as an adjective, not as a noun: â€Å"She was born in a US territory,† but not â€Å"She was born in the US.†) 2. When one abbreviates states, should there be any punctuation after, say, TX? And are both the T and the X capitalized? The short form of state names based on US Postal Service usage and technically considered a symbol rather than an abbreviation omits periods, and both letters are capitalized. However, the symbol should be used only when listing an address or in a chart or other graphic element where space is at a premium. Newspaper style is to abbreviate according to The Associated Press Stylebook (for example, Tex.), but in many other periodicals and in most books, state names are usually spelled out in regular text. 3. I am teaching a business-writing course, and I want to know how to approach terms like SOP or any other abbreviation. Does one say â€Å"an SOP† or â€Å"a SOP†? I guess the same would apply to â€Å"getting a MA† or â€Å"getting an MA.† Because we pronounce each letter in these terms (â€Å"ess-oh-pee† and â€Å"em-ay†), rather than treating them as words (â€Å"sop† and â€Å"mah†), the first sound determines whether we use a or an when we speak or write the abbreviation. As with other words starting with the â€Å"ess† sound (especially or essential, for example), we precede SOP with an. The same goes for MA, just as in, say, eminent or embellishment. Testing phrases vocally is usually reliable (an seems easier to say before these terms than a does), though there are exceptions: â€Å"An historic occasion† is easier for me, at least to say than â€Å"a historic occasion,† though an is â€Å"wrong.† See this post for more information.

Managing business ethics in China Essay Example | Topics and Well Written Essays - 1750 words

Managing business ethics in China - Essay Example In the modern day business world, a manager needs to ensure adherence to business ethics in a firm’s quest for profiteering motives. However, recent developments have resulted in varied definitions of ethics, and each person has to use own judgement to differentiate between ethical and unethical practise. Moreover, the capacity of a business to adhere to ethical expectations is dependent on political, social, economic, and environmental factors of a market. This means that a firm should balance its business practice with environmental and social responsibility, and in adherence to the ethical guidelines stipulated by the government in the country of operation. In essence, the highest level of ethical practice involves business practices that aim to ensure economic, environmental and social sustainability. The Chinese economy is characterized with widespread criticism on high levels of unethical practices; including corruption that is touted to be the most detrimental factor of the economy. However, recent changes have seen a change in focus to adherence to ethical guidelines by managers, most of whom are learning how to incorporate the system into their businesses without seeming to suffer from the alienation by western values. The Chinese investors insist on charting their own path to ethical practice despite the assimilation of various western characteristics into its economic system. On august 26, 2010, Landau reported on BBC about a businessperson who tried to incorporate Christianity as a tool to entrench ethical practice among his employees, mainly by encouraging his employees to convert to the Christian faith. While this practice is not illegal, it brings up the question of how far managers can go to ensure ethical practises in their firms (Landau, 2010). Factors Influencing Et hical Practice in China Many factors have been blamed for the widespread unethical practices in China, but the most outstanding ones are philosophical beliefs, globalisation and the rapid changes that the Chinese economy undergoes. Philosophical Beliefs The main philosophical approaches taken by the Chinese are Confucianism, Taoism and Buddhism, all of which are based on the teachings of prominent thinkers who resided in the Far East. Confucius, the father of Confucianism, taught that the first obligation of every person is to the family, such that everyone is expected to take care of the needs of family members and close friends before extending favours to others. While this is a convenient way of living in day-to-day life, the philosophy may be destructive in the business world, as managers tend to hire their family members regardless of their qualifications. This has resulted in poor quality of Chinese products; erosion of work ethics since a favour leads to another, and the cycl e goes on despite detrimental effects to the economy. However, this does not mean that Confucianism only has negative effects on ethics; in fact, if applied correctly, the philosophy has three main aspects that promote ethical practise. These include the teachings on obedience, following laid down guidelines, and humanity (Suen, Cheung and Mondejar, 2007). Taoism incorporates the principles of learning the details of one's profession for improved workmanship, and promotion of maximum good for the greatest number of people. In addition, Taoism results in increased efficiency at the workplace though this is not the prime concern of the philosophy. Buddhism is the philosophy that encourages business personality to respect and preserve the business environment; and to create a healthy relationship between the business and the community around it. Any manager intending to do ethical business in China has to have an understanding of the perceptions of

Case Study- Company Situation (Financial Analysis & SWOT Analysis Essay

Case Study- Company Situation (Financial Analysis & SWOT Analysis only) - Essay Example Based on the rising revenues and margin data, it is possible to conclude that Inditex is at the growth phase of the life cycle, while Benetton, the GAP, and H&M are at maturity and stability phase, as their revenues and margins are declining. Financial Ratio Analysis - Inditex Profitability Gross profit margin of the company is fairly high – 59%, which implies that the company has effective outsourcing manufacturing strategy and has good relationships with suppliers. Both factors have positive impact on cost reduction. Operating profit margin is 18%, which means that the company makes 0,18 cents for every Euro of sales (before taxes). Net profit margin is 14% and it means that the company has good control over its costs. ROA ratio which is 19% means that the company is effectively using its investment, converting it into profit. ROE Liquidity Current ratio of the company is 2,0 suggests that the company has a good ability to pay back its short-term liabilities with the short-t erm assets it has. This means that Inditex is capable to continue its business expansion strategy and to avoid insolvency during the slower growth phases. The quick ratio of 1,5 means that Inditex position has enough liquid assets to cover its current liabilities. Thus, the company can implement its strategy of fast fashion being capable to pay quickly for its orders and to kepp short inventory turnover. Leverage Debt-to-Equity ratio (0.42) indicates that the company’s debt used to finance its operations is not so high and is a positive sign of strong financial position of the Inditex. This indicates that the company is financially strong enough to grow its business due to its profits rather than debts. Long-term debt-to-equity ratio is relatively low and indicates on the company’s financial stability. Activity Inventory turnover at 4,50 indicates that the company has efficient supply chain and can continue taking its course of fast fashion retailer. Days of inventory ratio is equal to average 81.0 days. This indicator seems to be fairly high for the company focusing on fast fashion strategy. Average collection period is 13,4 days, which is quite low and therefore optimal for Inditex to continue its aggressive business development strategy. Financial Analysis has shown that Zara’s overall financial position is very strong and enabling for implementing its strategy of future sales and stores’ growth. SWOT Analysis Strengths The company’s strategy is based on aggressive multichannel global business expansion which is implemented due to its flexible business model based on having the right fashions at the right time at affordable prices. Financial state of the company rated as â€Å"healthy† allows the company to have enough capital for future growth and investments. Global expansion of Zara’s stores and its responsive marketing strategy increase global brand awareness. All these result in strong sales and revenue growth. Effective supply chain management allows the company to be competitive on the market balancing the quality of its goods and affordable prices for mass market consumers. Excellent human resource management is another strategic strength of the company which enables the company to grow its sales and gain positive reputation. Design of new stores in

Frederick Douglass’s Narrative :: Essays Papers

Frederick Douglass’s Narrative In Frederick Douglass’s Narrative, Douglas himself narrates the novel using story telling to bring both the reader into the story, and the theme into focus. Through his narration, Douglass also uses narrative strategies like anecdotes, and plot twists. Even with it being a true story, Douglass brings the readers’ attention to a peak with these techniques making the story interesting and appealing. The most influential technique used by Douglass is story telling. He uses little stories, or stories-within-a-story, to make the reader pay attention. With descriptive tales of the plantations he worked on, the beatings and torture of slaves, and learning to read and write, he not only gets the attention of the readers, but he gets them to understand his point of view. For example at the beginning of the narrative Douglass tells a story of his aunt being beating, â€Å"I have often been awakened at the dawn of day by the most heart-rendering shrieks of an own aunt of mine,† (3). He goes on and gets even more graphic and descriptive, â€Å"The louder she screamed, the harder he whipped; and where the blood ran fastest, there he whipped longest.† (4). Also early in the novel, Douglass writes of the plantation he grew up on, â€Å"There were no beds given the slaves, unless one coarse blanket be considered such,† (6). Soon after being sold to Mr. and Mrs. Au ld, he was taught the alphabet. He uses this experience to show to his audience that he is very literate despite his masters’ wishes, â€Å"If you teach that nigger how to read there would be no keeping him,† (20). So this story shows some more cruelty from his master. Just for reading he would be sold, which shows unfair treatment to the reader. Another similar technique used by Douglass very effectively is anecdotes. He uses anecdotes throughout the story to bring a humorous or interesting little side story into the readers’ minds. One good example of this is when he is talking about slave songs, â€Å"I have often been utterly astonished, since I came to the north, to find persons who could speak of the singing, among slaves, as evidence of their contentment and happiness.† (9). This shows the readers of his concerns by just adding a brief story in to interest the reader.

A Review of ‘Of Mice and Men’ Essay

Of Mice and Men was written by John Steinbeck in 1939, during the Great American Depression. It tells the story of two men striving to understand their own unique place in the world. Traveling in search of work, George and his simple-minded friend Lennie have nothing in the world except each other and the dream they share: to one day settle down in a farm of their own and count out their days. Eventually they find work on a ranch, their hopes are doomed as Lennie becomes a victim of his own strength leaving their dream to be crushed. Much of Of Mice and Men is based upon Steinbeck’s life and experiences. He highlights many social issues which he experienced first hand. For example, the climatic changes in the West of America resulting in destruction of fertile land, this had supported the homesteaders represented in the novel by the ‘promised joy’ dreamt of by the workers in the story. Another problem shown in the novel is the great financial collapse of 1929 which heralded the Depression that increased unemployment and poverty through the United States. Because of these problems intinerant American workers were exploited by farm owners on low pay and appalling conditions. They were only in demand for short periods of time causing them to have to save enough from seasonal work to support for the rest of the year and their extreme mobile lifestyles. Most of the characters in the book face many of these problems or are suffering from them especially the main characters, George and Lennie. George is a small, intelligent man. He is very strong-minded but also like most of the characters in the book very dreamy. He is very keen to change the monotomy of his present situation. Lennie, is a huge, lumbering, kind but child-like man. Although he has a terror of violence he is a man of great physical strength, something he is quite unaware of causing him to be clumsy. Lennie has an obsession with petting small animals that occurs throughout the book. He is very passive it is for this reason, in my opnion that George and Lennie are the incomplete halves of one whole person. George keeps Lennie by his side partly for comfort and friendship, but mainly as he is very strong and can work on a farm better than most people. Lennie is both an advantage and hindrance to George. George also supports Lennie, helps him and puts ideas in his head, wh ich keep him motivated but mainly acts as a fatherly figure. On arrival at the ranch one of the first characters George and Lennie meet is Candy, the oldest ranch worker who is coming to the end of his life. Candy is a very warm character in my opnion. He shares the dream that George and Lennie do, and therefore they become attractive ‘friends’ to him. He is a gossip and tells the newcomers of the ranch workers and owners. He tells George and Lennie about Curley and his newly wed wife. Curley is a small man, because of his height disadvantage he dislikes tall men. He is continually agressive and always trying to show his masculanity. He is humilated by his wife’s disastifaction and needs to boost his confidence. Curley’s wife’s name is never mentioned in the book it is for this reason she comes across as Curley’s possession. She is portrayed in the book as a tarty, flirtatious woman, who is ‘friendly’ to the men who work on the ranch. She claims not being understood in the book. Curley†™s wife has often been caught by other members of the ranch giving Slim and Carlson the eye. Slim is a friendly and gentle character compared to the others. He is a dignified master craftsman. Slim in my opnion is descibed by Steinbeck as an idealised character, however, his words and actions are quite realistic. Carlson is the more agressive character, we do not know that much about him but he usually appears in violent scenes. He is not a very sensative man. One of my favourite characters is Crooks. Crooks is a literate black cripple who tends horses. He interests me because his natural personality has been taken away from him by years of racism which I am very against. He is a very lonely character and has been automatically rejected in the novel by the other characters. My other favourite character is Lennie because of his unusual personality and need for a father figure despite being a fully grown man. In my opnion one cannot help but to feel sorry for Lennie. Within the story their are many themes, important ideas that run through the book. One of my favourites is dreams, each character has their own dream which is used throughout the book. The majority involve the ‘American Dream’, to be able to ‘live off the fatta the lan’. Curley’s wife’s dream revolves around Hollywood and being a moviestar but her dream she believes was ruined by her mother. She is also lonely just like many of the other characters, this is another theme in the book. Each of the workers is an induvidual and works for themselves. They all seek comfort in different things such as Candy in his dog. However, quite early on in the book Candy’s dog is killed, this is the first mention of violence. Throughout the book the world of the men is filled with unneccesary violence. The killing of the dog is quite similar to that of Lennie at the end of the book. Alot of authority is shown within the book aswell such as the condition of the worker’s living area and the Boss’s clothes, black and severe. However I feel the book is centred on the idea of mutual dependence. Each of the main two characters depends on each other hugely. But this relationship, at the end of the book, is breached and George takes advantage of Lennie who trusts him, and kills him, so that his dream is secured. The book is written in an easy to read form, it is not in the country language they would of spoken, but in proper English the majority of the book. The story is out of date of course, but the actual language and style used in the book is quite modern. I really like the way that Steinbeck at the beginning of each chapter gives you a vivid description of the surrondings. It is for this reason that although there have been many films made of this book nothing can compare to the pictures the pages of this book generates inside your mind’s eye and as you turn the final page these pictures stay with you. At first glance the story was not very enthralling but as I got deeper into the plot I started to really enjoy it. As I got more into the book I started to think more about the themes and characters of the book which drew me in to it even more. It is the kind of book that is not only a story but also holds an interesting background behind it and applies to the history of America and the Great Depression. It is for this reason I feel it deserves its title as a classic and I would recommend it to any reader.
