Internal Accountant's Report to Management (Accounting) Essay

Internal Accountant's Report to Management (Accounting) - Essay Example The government has initially failed to incorporate any major barriers to overcome the disaster of fraud, but in recent times some positive steps have been taken in this regard. There are several corruption schemes developed within the organization which are organized to aid fraud and abuse. The company needs to be aware of these which can cause loss of revenue and information alike. A kickback takes place when the fraud perpetrator enjoys the benefit of the overpayment of a good or service. It is easy to exercise such kind of a fraud and to get employees involved in such kind of activities. (Expert Fraud, 2009) Employees involved in the approval of contracts may have an upper hand inn this regard. This may also be referred to as skimming schemes. This kind of corruption takes place while the cash is paid by the customer to the cashier and before it is recorded in the accounting records. Since there is no recorded transaction, it is difficult to detect this kind of corruption scheme. This is one of the most common kinds of corruption schemes that take place within the organization. Employees who have access to records and are involved in the recording and approval of transactions can understate or overstate the expenses or revenues for their benefit. This largely happens when their remuneration is determined by profit and gains etc. Bribery can be a major issue of corruption within the company which can cause loss of confidential and important information pertaining to the entity. It may lead to a loss of precious revenue as well as dent the reputation of the company.

Climate Change Effects on Agriculture

Climate Change Effects on Agriculture Climate change is a change in average weather over certain periods of time. Issues about the climate change have been going on for quite some time now. The main issue is of course whether the Earth is experiencing climate change or not. The respond to this issue is surely positive although countless number of arguments is being highlighted regarding this issue. People usually confuse the climate change with the variations of weather that occurs constantly. This is wrong since the climate change is the change in average weather as being stated in the definition earlier. Climate change is also being observed for a certain period of time usually for a long time period ranges from decades to millions of years. Research that have been done and still going on about this issue offer a scientific assurance and great amount of data that supports the argument that the Earth is experiencing climate change. Various types of data like temperature variations, precipitation and wind patterns are us ed regarding this issue. These data record variations since they are affected by the dynamic processes on Earth such as instability of sunlight intensity and in recent times the human activities. Climate change effect all sort of people around the world and but the main group of people that will be affected the most is the poor population of the world. This is based on the facts that they rely mostly on their natural resource base for instance agriculture, fisheries and tourism activities. These types of industries are known as the climate sensitive industries which contribute to a vital number of national gross domestic products (GDP) (11). Agriculture share in total GDP at world stage is approximately 13% in developing countries and 2% in developed countries (5). Australia reliance on agricultural industry is quite significant although it is a developed country. The agriculture industry only contributes approximately 2% of the national GDP in Australia but around 66.7% of its products are being exported and this contributes approximately 18% of total Australian merchandise exports (8). Australian Governments Department of Climate Change reports that the interdependence between agriculture and economy was observed during the terrible droughts in 2002 to 2003 where the gross value of agricultural production decreased by 19% (approximately $32 billion) which accounts for the reduced of GDP by 1% (1). The relation between climate change and agriculture is a subjective matter and researches have been going on for quite some time now to find out what are the effects of climate change on agriculture and also the effects of agriculture on climate change. Most farmers are aware that they have to grow crops and rear animals depending on the local climate. This is important since the weather plays a very important role in determining the quantity and quality of the crops despite a lot of technological advances being introduced like genetically modified organisms, improved irrigation system and seed variation. This fact is being accentuated by Wall and Smit (2005) (4) who said that the main aspects in the success of agri-food sector are the weather and climate conditions. The climate impacts on agriculture are best being observed at local stage rather than at global stage because the impacts are more related to local climate. A detailed insight on the interrelation between climate change and Australian agriculture will be provided in this paper. This is due to the fact that agriculture plays an important role in Australian economy and is at risk caused by the adverse effects of climate change. The projected changes of climate, effects of climate change on the Australian agriculture, effects of Australian agriculture on climate change, ways to lessen the effects by means of mitigation and adaptation will be discussed in detail later in this paper. Australia is a big country and includes various types of climate. The temperature increase is difference from one region to another. In this case, the temperature average is taken into account where the estimated temperature increase is 1à ¢Ã‚ Ã‚ °C to 5à ¢Ã‚ Ã‚ °C in 2070 contrast to that in 1990 (CSIRO and Bureau of Meteorology (BoM), 2007, Table 1.0 in ABARE 200) (8). In general, the coastal areas of Australia will experience smaller number of temperature increase compared to the inland area of Australia. The changes in precipitation level are also being considered in order to observe the changes of climate. This type of change is less definite compared to the changes in temperature and the precipitation patterns are notably different at regional stage (IPCC 2007) (8). According to the modelling, the warming of Earth will anticipated to increase the precipitation level over Southern and Eastern Australia (7). According to CSIRO and BoM (2007), Australia will be expecting 20% more drought months by 2030, by taking the drought months in 1990 as a comparison (8). This number will be increased by 2070 with 40% more drought months are expected in Eastern Australia while 80% more drought months in South Western Australia (8). There will be also an increase in the number of flood occurrence and soils erosion as a results of the high number of precipitation level and longer drought throughout Australia (CSIRO and BoM 2007) (8). According to Garnaut Climate Change Review, the number of days with extreme fire weather will be increase approximately 5% to 25% in 2013 (6). Climate change can be both beneficial and detrimental to the agriculture industry. Which one plays the main role is still in question and arguments are still going on. The sure thing is that the climate change will certainly affect agriculture industry since this industry depends a lot on the climatic conditions. According to the Garnaut Climate Change Review, crop production is affected directly by the temperature changes, average rainfall rate changes, rainfall distribution over a year and rainfall variability (6). For example, temperature increase and rainfall decrease will results in the smaller amount of wheat yields and land values in all agricultural industries including crops, mixed and livestock by approximately 7% to 16% (10). Changes in the important climate variables in Australia are also results in the loss of agricultural production, decrease in crop yields, pasture growth and livestock production returns and increase in the cost of agricultural production (8). Climate change can also be beneficial to the agricultural industry as being said earlier. The beneficial effect includes the increase rate of photosynthesis that leads to higher crop production in certain plants due to the increasing number of carbon dioxide emissions (6). This is supported by John Houghton, the author of the book titled Global Warming by saying that the carbon dioxide fertilisation effect will leads to higher productivity, C3 plants in particular (9). On the other hand, this relation is complex and could possibly be compensate by the temperature increase and decrease in the water availability (1). Climate change effects on the agricultural are usually depends on the geographical aspect of an area and also the capability to adapt to them. According to a report, in mid to high latitude regions, moderate local temperature increase will results in small beneficial effects on crop yields, despite the fact that the same moderate local temperature increase will results in detrimental effects on yield crop (2). In a book titled Global Warming wrote by John Houghton, the writer states that with detailed knowledge of the conditions required by different species and the expertise in breeding techniques and genetic manipulation available today, there should be little difficulty in matching crops to new climatic conditions over large parts of the world (9). The statement is true but unfortunately it is only applicable to crops that take over a year or two to mature. Agriculture itself has its own effect on the climate change. The main reason is because the massive emissions of greenhouse gases which is one of the contributors to global climate change. According to Australian Governments Department of Agriculture, Fisheries and Forestry (DAFF), the Australian agricultural sector is the second highest source for greenhouse gases behind the electricity production, with approximately 18% of the overall national emissions produce by on farm activities (3). The highest amount of emissions (12% of the national greenhouse gas emissions) is methane (CH4), a main greenhouse gas produce by livestock, followed by nitrous oxide (NO2) produce by fertilized soils that contributes 3% of Australias greenhouse gas emissions, and the remaining amount is represented by carbon dioxide (CO2) (3). At world stage, Australias per capita emissions results from agriculture activities contributes to more than six times the world average, more than four times the average Or ganization for Economic CO-operation and Development (OECD) countries emissions and the third highest in OECD (6). It is proven that the Australian agricultural activities are very much vulnerable to the effects of climate change and also the effects of Australian agriculture on global climate change. There are many ways to deal with these two problems. The best ways to deal with this situation are to mitigate to lessen the effects and also to adapt to the foreseeable changes. The effects of agricultural activities on the climate change results in the establishment of international agreement, conventions and conferences as an effort to solve this problem. DAFF has prepared the Action Plan consists of a number of measures focussing on decreasing the CH4 and N2O emissions and discovering further prospect to encourage enhanced efficiency, understanding prospect to decrease the energy use in agriculture, promoting cost efficient alternatives to fossil fuels and developing biosequestration prospect in agriculture (6). Moreover, the emission trading scheme in Australian agriculture industry introduced by the government is also a way to decrease the adverse effects of climate change by making sure that farmers taking appropriate steps to reduce their carbon footprint and at the same increasing the net farm profits (8). Careful and principled approaches have to be taken to make sure that the design of the scheme does not create needless costs on the Australians (6 ). Another method is adaptation. The definition of adaptation is a structure modified to fit a changed environment. In this case, the modification that can be done to face inescapable climate risks. ABARE (2007) reports that the adaptation in agriculture could incorporate altering the species planted to those with more suitable thermal time and vernalisation requirements and with enhanced resistance to heat, frosts or drought; altering application times and quantity of fertiliser or irrigated water to sustain quality and growth; altering pasture rotations and grazing times; and supplying additional feeding to livestock (8). Another step is to increase the efficiency of water delivery which helps in reducing the declines in supply of water for irrigated agriculture due to the climate change (6). The climate change that strike the Earth which results in temperature and precipitation increase plus the greater rate of extreme weather events are understood to have significant effects both beneficial and detrimental on agricultural sector. On the contrary, agriculture industry also contributes to the climate change, mostly owing to the greenhouse gas emissions. Consequently, mitigation and adaptation approaches have to be taken in order to deal with this problem.

Psychotherapy Versus Pharmacotherapy :: Biology Essays Research Papers

Psychotherapy Versus Pharmacotherapy: Is One Better than the other? One of the most startling things to me at the beginning of the Neurobiology and behavior course was learning about the existence of "reductionism." That is, those who do not believe there is a human soul or necessarily even a mind. Instead, as I understood it, reductionism says we are all a product of our neurons and the firings that take place in the brain and nervous system. Those scientists, from what we discussed, might claim that disorders that take place in human behavior (such as schizophrenia, obsessive-compulsive disorder, or even depression) are all functions of neurotransmitters and the firings of neurons in the brain. In order to cure ailments such as these, certain psychiatrists or doctors might rely heavily and solely on medication. This type of treatment is known as the pharmacotherapy approach, in which medication is the primary tool used for curing patients. However, this idea did not ring true as necessarily the best or only approach to human disorders, especially t o a psyche major such as myself. I decided to then delve into the Internet to see people's views as well as actual statistics on which treatment, psychotherapy or pharmacotherapy, was indeed better. What I found was that a combination of the two seems to be the best bet in treating patients, and I will show evidence to support this as I talk about each topic individually, and then discuss their merits when used together. Also, in the scope of a paper such as this, I will look at both sides of the two treatments specifically for depression, since that is the best way to discuss specific statistics and for recovery. (3) WHAT IS PSYCHOTHERAPY? Just for a brief overview, psychotherapy is seen as a method of treating symptoms of distress in patients to help them return to a normal level of functioning. It is used as a medical tool to help a person overcome difficulties. Typical therapy is the kind most of us are familiar with, 50 minute sessions that are once a week with a therapist. The main focuses is for a patient to better understand their circumstances, the best ways to deal with them, and who they are as a person. Usually, if patients have a behavior specific problem, the APA homepage says sessions last an average of 16 visits. (APA homepage reference). Technically, the therapist has an interview with an individual to find out who they are as a person, their background, and then works from there to help heal and discuss the problems that have been affecting their daily functioning.

Dont get me started on… Valentine s Day

Valentine’ s Day is trying to abduct me into a fake world where everything is glorious and perfect, a world we all wish to be living in. February 14th is the date I most dread every year. Couples get loved up and forget about the important things in life, such as working nine to five to pay the enormous bills that are piled in a drawer or scattered in the living room. Using Valentine’s Day as a runaway from bills isn’t going to make things better. Running away from Valentine’s Day sounds more appealing, it stop’s us from meeting women like these: 1) The hopefuls: These are women who get excited on Valentine’s Day because they believe their special person is out there somewhere, and loneliness isn’t an option. 2) The women who know love only exists in fairytales. These women would sit alone watching a romantic movie. They would cry, curled up on the sofa, every time there’s a romantic scene, while their full mug of hot chocolate gently warms the palms of their hands. Valentines Day is an excuse to advertise couples kissing and holding hands in public. Why would you want to advertise kissing? Which leads to interaction, which surely leads to†¦ yeah, you get my point? It’s not the best example for kids now-a-days is it? Wherever you go, even at the local shop, you’re reminded of this day with hearts, cupids and silly poems on the front of handmade cards. Believe it or not, I caught the bus and I went to town for a small portion of chips with sausage in batter, My FAVOURITE. And on the standing notice board, written in red chalk was: VALENTINES DAY OFFER, small portion of chips and sausage in batter,  £2.99 only. What a massive bargain. I’d never thought I’d hate to love the meal I always devour, little did I know.  £2.99 was a bargain, but I turned away and went in the nearby corner shop, to pick up some cheese and onion crisps instead. At least I could enjoy eating without the reminder of Valentine’s Day on my back. We all know when it’s coming, we’re not stupid. Living close to cinemas, restaurants, shopping centres, bowling alleys and night-clubs could be perceived to be an incredible place to live; everything is close by (except the chip shop). I guess it’s convenient as I’m quite out going, but it is the worse place to live on February 14th. Why? Because the whole area is full of teenagers drunk with fatigue, and middle-aged couples walking tall and ecstatic as if they are The bee’s knees. The only people with class on this irritating day are old people, they are respectful and they don’t go out with the hundred-and -something year old partner. They keep to themselves, like everyone should. Right? People that go out on Valentine’s Day are not paying attention to others feelings, now how selfish is that? Husbands and wives become immediately closer in 24 hours however, after 24 hours it was like they never were. Love is unconditional and is â€Å"life-long† if you love the person. But Valentine’s Day only lasts 24 hours. So, what about the other 364 days? We don’t have love your pet day, because you’re supposed to do that anyway. New years and Christmas are two good reasons for going out and celebrating. A new year is a day where we all are overwhelmed for the year to coming, while Christmas is celebrating Jesus’ birthday. And then there’s Valentine’s Day†¦ An interesting way for the government to continue making a ridiculous amount of money – which would probably be spent on single parents benefits. This makes me think. Government= a greedy bunch of people who needs money to operate. So that’s it. Valentine’s Day is just a day the government make money, they don’t care about lovers. People are not thinking outside the box and why there really is a valentine’s day, it’s all a part of the government’s evil and sick plan.

Dead Man Walikng essays

Dead Man Walikng essays In Tim Robbins Dead Man Walking we are introduced to a caring nun, Sister Helen Prejean, who receives a desperate letter from a death row inmate, Matthew Ponsulate, trying to find help to avoid execution for murder. The audience becomes enveloped in their story as we are shown, over the course of the time until the convict's death, the troubling issues and emotions with which Sister Prejean is faced. She becomes empathetic and agrees to become this mans spiritual advisor until the day of his execution. As the days continue to count down, we join the characters in their desperate attempt to receive a stay of execution from the court. Throughout their struggle we also become aware of discontent coming from the parents of the victims. They are absolutely outraged at the idea that a nun would be protecting such a monster. Despite their views, she continues to reach out to Matthew and assist him on his way to salvation. In the end, she must decide how she will deal with the paradox of car ing for the condemned man while at the same time understanding the hideousness of his crimes. The characters and setting of this play were among some of the most unique I have seen in onstage performances. The simplicity of the props and background is what I feel made it so interesting. They allowed the audience to more intensely focus on the characters and the action of the play without being too distracted by fancy backdrops or extravagant lighting. There was also a fantastic use of film throughout the production. On the prison-like backdrops, scenes were flashed from the brutal crime, gradually revealing the truth about the events that had occurred. This gave the audience an omniscient role in the play. The characters themselves, I thought, were portrayed in a manner such that one could truly connect with their feelings and intentions. In the case of Sister Prejean, the audience could easily recognize that she had nothing but the best of ...

The Greek Hero vs The AngloSaxon Hero essays

The Greek Hero vs The AngloSaxon Hero essays The Greek Hero vs. The Anglo-Saxon Hero The hero stands as an archetype of who we should be and who we wish to be. However, the hero has inherent flaws which we do not wish to strive towards. In literature, these flaws are not used as examples of what we should be but rather as examples of what not to be. This is especially dominant in the Greek hero. While the Greek hero follows his fate, making serious mistakes and having a fairly simple life, the Anglo-Saxon "super" hero tries, and may succeed, to change his fate, while dealing with a fairly complex life. The Greek hero is strong and mighty while his wit and intelligence are highly valued. In the Greek tragedy, the hero struggles to avoid many flaws. Among these flaws are ambition, foolishness, stubbornness, and hubris-the excessive component of pride. He must overcome his predestined fate-a task which is impossible. From the beginning of the tale, it is already clear that the hero will ultimately fail with the only way out being death. In Oedipus, the hero is already confronted with a load of information about his family and gouges his eyes out. At this point, when he tries to outwit his fate he has already lost The Anglo-Saxon hero must also deal with his "fate" but tries, and usually succeeds, to change it. While the Greek hero battles his fate with his excessive pride and intelligence, the Anglo-Saxon hero tries to eliminate his doom by force. The Anglo-Saxon hero is considered a barbarian of sorts due to his sometimes unethical and immoral views and courses of action. At the end, the Anglo-Saxon succeeds in altering his fate though. The Greek hero is so normal, that the reader can relate to him. He is usually a "common" human being with no extraordinary life. His story seems believable, even possible. We would have no hard time imagining the hero's conflict as ...

Similarities and Differences of Mesopotamia and Shang China Essays

Similarities and Differences of Mesopotamia and Shang China Essays Similarities and Differences of Mesopotamia and Shang China Paper Similarities and Differences of Mesopotamia and Shang China Paper Features | Mesopotamia | Shang China| Community Development * Large settlements * Stable food supply * Trade and communication | Most of the settlements began along the borders of Mesopotamia and date from the 10th to the 9th millennium BC. Because of the dry climate and flooding of the river, farmers had to adapt and eventually began to grow crops of fruits and vegetables. | People settled towards the middle or lower parts of the Yellow River in places called urban centers. They built the 1st real cities in China; they also built palaces and temples. The settlements began to start crops along the Yellow and Yangtze Rivers. In the growing industry fishing became popular just like agriculture, even handcrafting. | Organized Systems * Religious systems * Military authority * Civil authority * Economic authority | Sumerians believed in Polytheism and devoted all their prayers and offerings to their Gods, in believing that they controlled the nature of their agriculture. City-states ruled by a king who claimed divine authority. The government helped regulate religion and enforce duties, also providing a system of courts for justice. To keep his people in order King Hammurabi created a document for his people creating justice for the innocent and the guilty. Each city-state regulated their own trade and controlled much of their own businesses. Their business dealt with agriculture and clothing, basic needs for a society. | The Shang Dynasty practiced Polytheism; their most important God was Di. They also believed in ancestor worship which was probably around for thousands of years after they started it. A Shang king could gather an army of about 5,000 for in border campaigns or call all his forces in a grand army around 13,000 to face down serious threats such as insurrection and invasion. The king began to tax the people for agriculture and this outraged them and attacks started to happen. The Shang began to lose control. In their economy, they began to fish as an industry; they also sold hand crafted goods, which became industries. | Complex Social Structures * Division of labor * Division of power * Gender roles * Class structure | Division of labor meant that farmers would buy goods from other workers. Kings thought of themselves as superior to all, they believed of themselves as divine authority. In gender, the men were the hunter-gatherers and women picked berries. The Sumerians had a specific class system. The highest class was the priests, middle class were merchants, and the majority was city-states, which was lower class, made up of farmers. | In the class structure and division of labor, nobles had the most power followed by craftsmen, peasant farmers, and then slaves. Most of the Shang people were farmers. Even though class differences affected gender roles lower-class women were to stay home cook, clean the house, take care of the kids, and make clothes for the whole family. But the division of labor was also important between men and women in different civilizations and social classes. | Form of Writing * Statement of values * Business records * Legal records * Continuity of traditions | To keep track of their trades, the Sumerians had to develop a writing system. They wrote all of their transactions on clay tablets. These were the first legal records, displaying numbers of their traded goods. The Shang people showed the importance of family and Shang society. This value was carried out through China’s history to present day. Even the ritual of ancestor worship. | Artistic Achievements * Visual arts * Literature * Architecture * Music | Art was made up of natural resource; stone, shells, and marble. The societies depended on art in order to find organization and structure. Peo ple of Mesopotamia recorded all their literary works on clay tablets, which include folktales, prayers, hymns, proverbs, personal letters, and fables. Religion played a big part in architecture. Temples were centers of city-states to be worshipped. Instruments are commonly present in many forms artwork; musical notes and lyrics have been found. Music was a significant and sophisticated role. | In the industry of hand crafted goods their pottery showed various types of patterns carved or painted onto them, even stones had fine pictures painted onto them. They usually wrote in a special ink, they had various forms of writing like hieroglyphics, and self-explanatory characters. They usually carved these onto animal bones or tortoise shells. Architecture was built into houses made of wood or carved out of the earth into rows. They listened to folk music and palace music. With their practice in bronze they made fine musical instruments, people engaged into music but they were divided into 3 sections; Wu, music slavery, and Gu. | Developed Technology * Technical process * Technology and work * Technology and settlement patterns | The development of the calendar was based on their observations and studies of the stars, moon, and sky. They also established a number system; a year was cut into 12 months, a month into 30 days, a day into 12 hours, an hour into 60 minutes, and a minute into 60 seconds. They also divided a circle into 360 degrees of the 60 arc minutes. Settlement patterns were based on the environment of the area and the need for a stable water supply. | The Shang developed the cycle of the moon, their calendar lasted for 366 days, and they have many records about solar eclipse, lunar eclipse and nova. The calendar system continued to advance and in the area of math. Settlement patterns on the Shang period are dispersed, in a variety of villages and they also have ritual or ceremonial centers. | Features | Mohenjo-Daro | Egypt | Community Development * Large settlements * Stable food supply * Trade and communication| Mohenjo- Daro is one of the largest Indus cities also being one of the best preserved urban centers of Indus Civilization. Their food consisted of wheat, barley, millet, fruit, vegetables and fish. They were able to grow grain and vegetable because the river would flood sometime. They also had fish because the city was along the Indus River. Their trading network moved from the coast to the Indus plain, and trade routes passing the Bolan Valley to the west. | Different environments affected settlement areas but the earliest known settlement is the Nile Valley or Mermida on the western Delta. Another settlement would be The Fayum. Both these settlements were along the Nile and all inhabitants found had a good supply of fish, meat, and cereal grain for their diet. The Egyptians would trade gold and farmers harvested all year long, especially flax since it was an important source in textile fiber. Organized Systems * Religious systems * Military authority * Civil authority * Economic authority | Artifacts point to Polytheism, certain plants and animals were sacred to them. There was no military strength instead they were governed through trade and religion. There haven’t been any signs of weapons being used. The rulers carried animal symbols each having their own meaning. It is said that the people ruled themselves; there is no evidence of leader’s authority. Their economy was entirely dominated by agriculture, but there was also hunting, pottery, metal and minerals. The Egyptians believed in polytheism, the main Gods they worshipped were, Amon-Re, Osiris, Set, and Isis. They strongly believed in the afterlife thus their need for mummification. The Egyptians had a powerful military force; an important attribute of the pharaoh was martial prowess. The king was the only landholder, warrior, priest, and judge. Everyone else worked below him. The Egyptian economy was made up of trading gold and wheat. The Egyptians served their king by building cities and markets to keep the economy going. Complex Social Structures * Division of labor * Division of power * Gender roles * Class structures| Their social structure is almost like the one we have today; divided up into wealthy and skilled workers. Women were responsible for gathering, cooking and taking care of the children. The men were to hunt. | Egyptians had a rigid class system from top to bottom, it was possible to move up classes but it was highly unlikely. What your father was, you were. The people at the top of the class structure owed a duty to those at the bottom. It was also a culture where women were valued unlike most cultures today; they worked and were praised for it. Pharaohs were always at the top of social classes, they were superior. | Form of Writing * Statement of values * Business records * Legal records * Continuity of traditions | Forms of writing were found in the ruins of Mohenjo-Daro. The seals often show animals are written in an unknown language. It is said that the language could be Dravidian or Sanskrit, but it is still undecided. | They Egyptians system value was just as important to them as it is to us today; it is also quite similar to ours. The difference would be what the Egyptians gave to their value system, like a secular and religious side. | Artistic Achievements * Visual arts * Literature * Architecture * Music | They made sculptures, clay models, and beaded items. These art pieces each had a different purpose and meaning. The clay models were for children’s enjoyment, sculptures were to show a person’s image or a place, and beaded items were used for decoration and jewelry, like today. Their buildings were made up of brick that goes on for miles in every direction; each block is centered on a grid. Pharaohs and Dignitaries kept their records on scribes, in the writing system called hieroglyphics. Hieroglyphics used picture symbols for ideas or sounds. Egyptian literature includes hymns to the gods, mythological and magical texts, and an extensive collection of mortuary texts. In stories; instructive literature, known as wisdom texts, poems, biographical and historical texts, and scientific treatises , even mathematical and medical texts. Architecture was based on perpendicular structures and inclined planes since there was no structural assistance except the strength and balance of the structure itself. Architects had to carefully plan out the way of the building. A ramp of adobe brick can be seen leading to the top of temple walls this was to allow artists to decorate the tops of walls and pillars. Egyptian art depicted their everyday lives. In tomb and temple drawings they show everyday living, models of people and animals, glass figures and containers, and jewelry made from gold and precious stones. | Developed Technology * Technical progress * Technology and work * Technology and settlement patterns | The closest technology would probably be their cleanliness. They had great drain and sewage systems. It was known as aquatic culture, where water and bathing played a central role. | Egyptians developed a water clock, sundial, pyramids, and tools to build these pyramids, and a time system. | Features | Olmec | Chavin | Community Development * Large settlements * Stable food supply * Trade and communication | San Lorenzo de Tenochtitlan, La Venta, Tres Zapotes, and Laguna de los Cerros, Olmec settlemenst have been found in these places. The Olmec relied on maize, and sunflower. Later they domesticated beans. They also gathered corozo palm nuts, squash, and chili. The Olmec had extensive trade routes. They traded raw materials and finished goods were traded across hundreds of miles. | A site of early monumental architecture in Peru and one of the oldest urban settlements of the New World.

Investment and portfolio analysis Essay Example | Topics and Well Written Essays - 1500 words

Investment and portfolio analysis - Essay Example On the contrary, Sharpe ratio refers to a measure of risk adjustment measure that utilizes standard deviation when computing portfolio returns and inherent risk associated with a particular portfolio (Ctaff, 2012). Empirical research asserts that if Sharpe ratio is higher it implies returns are better. Therefore, by utilizing standard deviation, Sharp ratio assumes that the relevant risk is total risk unlike Treynor ratio which assumes that the relevant risk is systematic (Ctaff, 2012). Both Treyon and Sharpe ratios are similar; however, the two measures differ in terms of how they determine of risk volatility. Whereby, Treyon ration utilizes beta while Sharp ratio tend to utilize standard deviation (Anric, 2013). Information ratio measures the ability of corporate managers to utilize skills/ luck to generate excess returns beyond the established benchmark. This ratio utilizes alpha elements as well as standard deviation to measure volatilities associated with a particular portfolio (Reilly and Brown, 2012). Therefore, information ratio assumes that the relevant risk is total where both systematic and unsystematic risks are combined (Harkins, 2012). Jensen alpha refers to a measure of portfolio returns predicted using capital asset pricing model. In addition, Jensen’s alpha assumes that relevant risk is systematic (Bacon, 2013). On the other hand, Sortino ratio refers to a ratio that helps to determine the difference between good and bad risk in sharp ratio. This ratio tends to be similar with Sharp ratio. However, it utilizes downward deviation making it slight different from sharp ratio. This ratio measures return that can be derived during volatility whereby, standard deviation may be utilized. Therefore, Sortino ratio assumes that relevant risk it total (Feibel and Vincent, 2011). 2. Discuss whether the present value of cash flow approach and the relative valuation approach to security valuation can be considered to be competitive or complementary. T he present value approach may utilize discount rate to discount cash flows generated by a particular project to determine their value. Additionally, the present value approach may be utilized in making valuations of different assets such as shares, real estate properties and even bonds (Feibel & Vincent, 2011). Whereby, a negative net present value indicates that a project may not be profitable. In addition, a positive net present value implies that a project may be profitable and therefore, such project should not be undertaken because it will expose the company at a greater risk. On the other hand, relative valuation approach focuses at valuing company stocks with those of company own historical method of valuation. In addition, relative valuation tends to compare company’s stocks with the market value of other similar assets to determine whether they can be suitable for investments (Feibel and Vincent, 2011). This means that similar stocks of a particular company should be compared with those stocks of companies operating in the same market. However, relative valuation approaches have some limitations. For example, all companies may not utilize the same corporate strategies and hence, great discrepancies may exist between companies (Feibel and Vince

Assignment 11 Example | Topics and Well Written Essays - 500 words

11 - Assignment Example This formal way of conducting business was adopted from the west as the Japanese were culturally a social group (Yukichi). Other people are seen to be walking into the restaurant, all dressed in similar fashion, long robes all trying to appear as though formal. There are people on the street all possessing the same artier and the same inferences can be drawn from the same. There are people who seem to be raising the flag. This shows that the Japanese are acquiring order and structure in their activities as raising the flag symbolizes the presence of a hierarchy which is adhered to. This too was gotten from the westerners who believed in order and conducting their affairs in a proper manner (Yukichi). This is in response to Fukuzawa Yukuchi’s urging to the Japanese people that they should pursue civilization and enlightenment i.e. western civilization. Together with other scholars, they advocated for the Japanese to mirror the westernized way of tasting, eating meat, wearing of western-style clothing and the dropping of Chinese customs that the westerners found odd. There are other people who seem to be soaring in the air. We garner an aspect of entertainment. The Japanese have finally let their guard down thanks to westernization because the Japanese are principally a reserved people (Yukichi). According to Lim Zexu, Queen Victoria should halt the opium trade because she has witnessed firsthand how the drug destroys its users and particularly in her own country. The letter to her says that Opium in her own country is prohibited because of the danger it poses to its users. Lim states that based on this reason alone, the Queen should not condone the trade in Opium, and should prescribe severe punishment to anyone who is found engaging in the said trade (Zexu). The Queen on stopping Opium trade will have the support of Heaven as it crown’s her with felicity, getting the blessing of long life and the security and stability of her descendants. Lim is

Gender equality is no longer important or a relevant concept. Consider Essay

Gender equality is no longer important or a relevant concept. Consider this statement in relation to the position of women in contemporary society - Essay Example For many years before acceptance of this law the woman struggled for their rights. In 1854 the woman have got the recognition of the right to inheritance, in 1864 the unmarried women began to be considered as the independent individuals. The married women have acquired such right only in 1888. Since this moment they have acquired the right to dispose the property belonging them (Fortmann, 2006). Sex equality is the feministic treatment of equality assumes an equality of sexes, that men and women should have equal shares in the social authority, equal access to public resources. The equality of sexes is not identity of sexes, identity of their attributes, characteristics. The term egalitarian theory (in this case is a synonym of the term equality of sexes) has undergone at least four stages of transformation. The idea of absolute equality between people as sample of a socially-fair society was primary. Historical development has shown that such concept is utopian. The ideas of similar "equalizing" of women and men also have the sad examples of realization. Involving of women in heavy kinds of work, "double burden" loadings on women, occurrence of "straw" orphans - the left children. And the most remarkable – the mass attempt of women to break the female identity, having accepted mans behavior and mans game rules for equality with men. The second stage in understanding of the term ‘equality’ was comprehension of necessity of equality of the rights of all citizens of a democratic society. Realization of this certainly progressive principle of social development has shown its inconsistency and weakness from the point of view of realization of the rights separate marginal groups (women, national minorities, etc.). From here there is an occurrence of the third stage of egalitarian theory in social development. The equality of rights of

For better or worse, the old saying about money making the world go round at least has a modicum of truth to it. This money, of course, is made through selling things, whether products or services, by way of taxing business establishments. To sell a service in particular requires a great deal of effort on the part of the salesman; events and at tractions are no exception among these. If anything, said need for a concerted effort applies even more so in this regard, due to the increased need to convince prospective customers that one’s offerings are actually good and are not, in fact, worthless. Given how much profit is at stake, it would be best to be aware of and display a certain degree of proficiency in event management – which refers to the administration and creation of various conferences, festivals and occasions (Ramsborg, 2008). As with any other type of management, event management requires a load of planning in order to succeed. Among other things, those in charge of such tasks need to be ready and willing to analyze and identify their prospective clients and target market as well as pick a proper event theme, for a start.

The general demand for both traditional and contemporary events has contributed greatly to the growth of this industry. Said events can be conducted for any purpose, be it organizational, cultural or personal in nature, but it should be obvious for anyone planning such events to want them to succeed.

Technology in particular has been a godsend, especially in that proper application of it expedites tasks, which no longer need quite as many people to get done right. This becomes much more readily apparent when the internet is factored into the equation. The so-called information superhighway is definitely a great help in this case, not only in spreading awareness regarding the event, but also when it comes to facilitating the growth of the firm in charge of the said event or attraction. Thanks in part to this, the industry of event management (and by extension, attraction management) has become even more lucrative and profitable than it already was.

All about Jupiter Essay Example | Topics and Well Written Essays - 1250 words

All about Jupiter - Essay Example The most accepted theory is that ice and other solid material combined to form its core. The core increased in size as it attracted other material from other sections of the Solar System resulting in an increased gravitational pull. â€Å"Eventually the core’s gravitational pull became strong enough to capture hydrogen and helium, which were abundant in the solar nebula.† (â€Å"Jupiter†, p. 200) That is why Jupiter consists primarily of hydrogen and helium. Jupiter rotates very quickly for a planet of its size, with a period of ten hours; it revolves around the sun once every eleven years. Like the other planets Jupiter orbits around the sun in an elliptical orbit. (â€Å"Jupiter†) It is approximately 480 million miles from the sun. (Simon) Jupiter is often seen high in the sky, and some its surface features such as its satellites can be seen with a telescope. â€Å"From our planet Jupiter looks like a bright star in the night sky.† (Simon, Introdu ction) It is one of the most luminous objects in the sky next to the Sun, the moon and Venus. Jupiter is considered one of the â€Å"gas planets† because its atmosphere is composed primarily of gas. It is two and a half times the mass of all the other planets in the Solar System combined. Jupiter is one of the Jovian (outer) planets; the other Jovian planets are Saturn Uranus and Neptune. There is no solid surface on Jupiter. Jupiter is composed primarily of hydrogen and helium. It is similar in composition to the Sun. In 2008, scientists were able to define the surface of Jupiter. â€Å"The surface of the planet is defined as the point where the pressure of the atmosphere is 1 bar, which is equal to the atmospheric pressure at Earth’s surface.† (Coffey, â€Å"Surface† n.pag) The pressure and temperature increase deep in its atmosphere, resulting in hydrogen being compressed into a liquid. Partially beneath its surface, the hydrogen hardens and becomes ca pable of conducting electricity. In this metallic layer, electrical currents resulting from the rapid rotation of Jupiter produces its immense magnetic field. In the middle of the planet its enormous pressure may support a solid core of rock that is approximately the size of Earth. Jupiter's upper atmosphere consists largely of hydrogen and a lesser percentage of helium. The interior of the planet is approximately 71% hydrogen, 24% helium and contains minimal amounts of other elements. The atmosphere also includes hints of methane, water vapor, ammonia, and silicon-based compounds. There are also traces of carbon, ethane, hydrogen sulfide, neon, oxygen, phosphate, and sulfur. The outermost layer of the atmosphere contains crystals of frozen ammonia. (â€Å"Jupiter† Wikipedia) The temperature on the surface is about -235 degrees F (-150 C). The temperature on Jupiter increases to about 70 degrees Fahrenheit deeper within its atmosphere. The winds continue to blow at approximat ely 450mph. (Holladay). The atmosphere in Jupiter increases in thickness until it reaches the ocean. The magnetic field in Jupiter is tremendous. Jupiter has the strongest magnetic field of all the planets. Millions of charged particles are confined to Jupiter’s magnetosphere: â€Å"the area in which magnetic field lines encircle the planet from pole to pole.† (â€Å"Jovian Giant†, para.3) Its rings and moons are entrenched in a radiation belt

Wheel of Fortune and Invocation by Flack Essay Example | Topics and Well Written Essays - 1000 words

Wheel of Fortune and Invocation by Flack - Essay Example The essay "Wheel of Fortune and Invocation by Flack" analyzes the Flack's paintings, heel of Fortune and Invocation. Both pieces feature an unrealistic collage of still life items, including a realistic human skull. The items included in these still lifes are not unrealistic in their depiction, but rather in their placement. Wheel of Fortune, for instance, makes any underlying structure impossible to discern while Invocation presents an abstract, dimensionless background. The illusionistic depiction of items such as the human skull, hourglass and nearly burned down candle classify Wheel of Fortune as a vanitas painting while similar images, minus the hourglass, are used in Invocation. Flack employs a full range of hues to produce a trompe l’oeil effect in many of these images. The paintings do differ in the way in which they are compositionally composed. Both use the human skull as focal point. In Invocation, the skull is placed in the geographical center of the painting with all other objects arranged around it. It is given a trompe l’oeil frame over which a paint tube, sitting next to the neck of the skull, drips a steady stream of red paint, and a candle, lit near the left edge of the image, burns. The composition is asymmetric with balance achieved by inversing round forms such as the base of the candle holder and the blooms of the bouquet. Wheel of Fortune, while also asymmetric, achieves its balance through the duplication of the skull. The original skull is placed off to the right side.

Vehicle Vibration Analysis

Vehicle Vibration Analysis It is known that vibration levels depend on various parameters, such as type of vehicle suspension, inflation pressure and condition of the tires, the speed of vehicle, road condition, vehicle load, etc. As this simulation is held on a 4-post shaker and tested vehicle is given, some of the factors should be ignored. Hence two factors are selected, tire inflation pressure and vehicle load, as test variables. 1. Effect of tire inflation pressure: This project will detect the dynamic performance of pickup truck with tire pressure at 50%, 100% and 150% of rated inflation. This variable is considered base on the principle of how the road excitation is damped all the way from tire-ground interfaces to the chassis. Tires are the most important parts of a car. The damping occurs at two points: the car suspension, which consists of a combination of bushes and the shock absorber with its different types depending on the car model, and the tires. This shock absorber is connected in parallel with a helical spring coil. In addition to shock absorbers and springs, the tires damp the road excitations. Although the damping effect of tires is small when compared to that of that of the shock absorbers and springs, this damping effect cannot be ignored. Under rough road excitation, tire sidewall and tire stiffness affect the dampening. Varying tire pressure will have a great impact on the damping coefficient of the tires. At overinflation con dition, tires tend to be stiff and transmit vibrations directly to the shock absorbers and other suspension components, and for tires themselves, the tread wear is severe along the center due to bulging of the tire structure at a high pressure. Since decreasing the pressure will decrease the stiffness of the tires, the effect will be greater damping before transmitting the excitation to the suspension components. But reducing it after a certain threshold will reduce the drivers car control and pose a danger to him and his surroundings. Driving with underinflated tires will cause uneven tread wear either, potentially lead to fatigue breakdown of the tires internal structure resulting in tread separation or other structural failure and also conversely degrade the car performance by increasing vibrations. Hence different tire inflation rate should be applied during testing and observe the difference of the performance of the unsprung system. 2. Effect of Vehicle Load It has been shown that the dynamics of a lightweight vehicle are more sensitive to payload parametric variations, i.e., passengers or freight loads, than a conventional vehicle. For example, a harsh turning may lead to rollover much more easily, or the maximal acceleration/deceleration is significantly reduced, when a large amount of payloads is placed on a lightweight vehicle. All these deviations in lightweight vehicle dynamic responses, even if sometimes trivial, can mean life or death, particularly under some critical maneuvers and challenging driving conditions. Fortunately, the existing numerous advanced parameter-adaptive vehicle control systems, such as adaptive traction/braking control, adaptive steering control and adaptive roll/lateral stability control, can partly relieve the aforementioned problems. However, these controllers originally were not targeted for lightweight vehicles and did not explicitly consider the vehicle payload variations, and more importantly, they se ldom generated the information on the unknown parameters. Since payload may count for a considerable part for a lightweight vehicle, the knowledge of the actual payload parameter values can greatly benefit the ride dynamics analyzation in lightweight vehicles. It is concluded by previous research that, for active suspensions, both ride and handling can be improved by reducing the vehicle load. In particular, when the total vehicle mass is kept constant, every 10% reduction in vehicle load contributes to a circa 6% reduction in r.m.s. sprung mass acceleration for the same level of wheel-hop. For active suspension vehicles, this provides a clearer picture of the unsprung load effect on vehicle ride dynamics.

The Privilege of the College Experience :: College Admissions Essays

The Privilege of the College Experience At age four, I was a firewoman, fighting to save the spirits and possessions of those faced with devastation. Twelve short months later, my occupation mutated into the daring role of a policewoman working to keep the peace. Later, still devoted to the sake of betterment, I finished my fourth year of law school and took my bar exam with F. Lee Bailey and Johnny Cochran. Nothing more notorious than a thief seemed to cross my 10-year-old mind. Unpractical but whole and with an intense fancy, I lived one hundred lives. Emitting the wonders of life into the ornate dream of childhood, I sailed though the adult world as a na†¢ve foreigner. Inevitably, the misconceptions of childhood soon turned to red, green, yellow and orange and fell frailly from the tree of life. Now a chance for an even more colorful future has arrived: college. As a young adult, dissecting and analyzing every feeling, occurrence, or loss that I experience, then writing about it, has become a way of life. Throughout my high school years, I have experienced many "firsts." These firsts embedded in me much more than book knowledge: the friendships, the new responsibilities, the leadership roles. The new experiences turned my fire fighting days into adulthood. However, the fire fighting skills were never lost; each childhood and adolescent lesson has kept me from falling in flames, and similar morals gained in college will fulfill the same role in my adult life. These writings that I look back on not only remind me of why I would love the privilege of gaining a degree in (field of study), but also paint a picture of a blooming thirst for challenge and a hunger for success. The privilege of the college experience is the privilege of eating from the tree of life. Fortunately, I learned early in "law school" that love and hate have close ties. On the tree of life, good and evil grow from the same branch, and shape the world as they fall. Education is the ultimate teacher of these principles. After years of rain or shine, my childhood images remain vivid and my feelings the same, for each leaf is sprouting from that same seed of adventure - the very seed that has been nourished with experience and showered with responsibilities, and now grows with petals thirsting for the passion of their sun: college.

Analysis of A Modest Proposal by Jonathan Swift :: essays research papers

This essay by Jonathan Swift is a brutal satire in which he suggests that the poor Irish families should kill their young children and eat them in order to eliminate the growing number of starving citizens. At this time is Ireland, there was extreme poverty and wide gap between the poor and the rich, the tenements and the landlords, respectively. Throughout the essay Swift uses satire and irony as a way to attack the indifference between classes. Swift is not seriously suggesting cannibalism, he is trying to make known the desperate state of the lower class and the need for a social and moral reform in Ireland. Jonathan Smith goes to extreme measures to explain his new plan to raise the economic wellbeing of his country. He explains what age is too young and what age is too old, in order to eat the tenants children when they are at their prime juiciness. He also gives a list of suggestions on how to cook them, ?A young healthy child well nursed, is, at a year old, a most delicious nourishing and wholesome food, whether stewed, roasted, baked, or boiled, and I make no doubt that it will equally serve in a fricassee, or a ragout.? All of this talk about eating children comes as a surprise because previous to this disturbing suggestion, Swift is ironically discussing the plight of starving beggars in Ireland. The reader is unprepared for the solution that he suggests. The idea of eating all the youth in the country is obviously self-defeating and is not being seriously suggested by the writer. He is simply trying to show how desperate the lower class is in Ireland. Swift introduces the reforms he is actually suggesting, taxing absentee landlords, of encouraging the domestic economy by buying Irish goods, of discouraging pride, vanity, idleness, by dismissing them in his essay by saying that they are impractical. However, these reforms greatly differ from his ?modest proposal? because instead of the poor sacrificing their children, it would involve the rich sacrificing some of their luxuries. He is trying to point out the fact that reforms that would be practical and beneficial to the people of Ireland are being overlooked for the convenience of the rich.

Review of Janet Abbate’s Inventing the Internet

Janet Abbate, Inventing the Internet, Massachusetts Institute of Technology, Cambridge, Massachusetts, 1999, 258 pages Janet Abbate’s Inventing the Internet explores the history of the Internet as â€Å"a tale of collaboration and conflict among a remarkable variety of players. † (3) Abbate’s writing concentrates on the Internet’s development through social and cultural influences. The book explores the evolution of the Internet from ARPANET to global networks.The Internet’s expansion has existed within an interworking web of innovators; government and military, computer scientists, graduate students, researchers, cable and phone companies, network users, etc. The details given by Abbate affirm the book’s claim that the Internet was not born of a single originating event. It, instead, progressed over time through the junction of advances in technology and needs in society. The Internet is an ever-adapting system, which is fresh and changing a t escalating rates yet has a history that crosses over several decades.Born within paranoia surrounding the Cold War and growing through many different forms, the Internet’s history is laid out chronologically in Abbate’s six chapters. In this informative and methodical chronicle, Abbate tracks the important teamwork of the Internet’s creators and societal needs in a detailed and entertaining volume of history. Despite the revolution of the Internet bringing about doorways to assorted information, it has done a bizarrely deprived job of recording its own history. As the Internets’ creators get older, it is essential to capture their first hand accounts of the history they made.In her book, Inventing the Internet, Abbate saves the early history of the Internet. The book is divided into six segments. The first segment relays White Heat and Cold War: The Origins and Meanings of Packet Switching that is primarily about packet switching. The second covers the political and technical challenges involved in Building the ARPANET: Challenges and Strategies, concerning the creation and struggles of ARPANET. The third segment covers user communities and their affect on the ARPANET in â€Å"The Most Neglected Element†: Users Transform the ARPANET.The fourth considers the shift made, From ARPANET to Internet approaching defense and research. The fifth section covers The Internet in the Arena of International Standards. The final section, Popularizing the Internet, shows the beginning of the wide spread of the Internet but before Internet connectivity becomes popular at the personal level. All things considered, the book states the expansions in Internet history between 1959 and 1991, with some proceedings to 1994. The author’s study of the Internet’s genesis makes systematic links between the technological development and its organizational, social, and cultural environment.There are many available histories on the Internet, in print and online. Most are well-documented information on technology and its history. Some mention the fundamental concepts of communication, information, and knowledge. Abbate's work, however, goes beyond ordinary facts and her findings are most revealing. The beginning of the Internet is well known. It was a United States Defense research program named ARPANET. The internal structure of ARPA that reared the network development during its first years is not as well known.Inventing the Internet explains how the little agency was created in 1958 to respond to the Soviets' successful launch of the world's first artificial satellite. ARPA did not own a laboratory. ARPA’s role was to create centers in universities through the financing of research projects in defense-related domains. When ARPA decided in 1969 to connect the supercomputers scattered among university campuses, it had no political or financial difficulty attracting the best computer scientists from all over the United States.The originality of ARPANET is this basic freedom, in contrast to market laws and official control. Inventing the Internet highlights ARPA and its brilliance, which seems to violate both the hands-off approach and the state-intervention ideology. ARPANET was born in an atmosphere of total confidence within a community whose total purpose was to connect the computer equipment from as many universities as possible, while striking the least restricting of standards. Packet-switching technology was the tool hat seemed to execute the fewest constraints so ARPANET was based on packet switching instead of the circuit-switching technology that characterized all other telecommunications networks in the world. Along the way, users and other developers took computer networking in directions that ARPA did not intend. Users rapidly made e-mail the most successful network application. Other countries tested the Internet with varying protocols and applications. The community of scient ists hard-pressed the National Science Foundation into action that overshadowed ARPA's in the 1990s.As new applications and pressures arose, the United States government moved toward privatization of the Internet in the 1990s. This development and the commercialization of personal computers helped build an advantageous atmosphere for the introduction of the hypertext system and web browsers. The World Wide Web turned out to be available even to beginners. Abbate argues successfully that the origins of the Internet â€Å"favored military values, such as survivability, flexibility, and high performance, over commercial goals, such as low cost, simplicity, or consumer appeal† (5).On one good side of things, it was these features that offered computer networks their keen adaptability and quick reaction to the unexpected demands of users. Per the cons, suggests Abbate, they could have caused defiance of commercialization in the system as ARPA did not visualize charging individuals to use the system the way the phone company charges individual telephone users. Based on detailed research in primary documents and extensive communication with many of the principals in the story, Abbate's history delivers the most detailed and revealing account.She succeeds in showing that both its developers and its users socially constructed this evolving technology. How might one know where they're going, if they don’t know where they have been? It's someway comforting to learn that a technology that seems to be new and ever-evolving actually has a history crossing several decades. This history of the Internet, a technology that modern people use on a daily basis in various arrangements, is outlined so perceptively in Janet Abbate’s, Inventing the Internet.

Investigating the Factors Affecting Tensile Strength of Human Hair Essay

Hypothesis There will be a difference in tensile strength in blonde hair and black hair of similar thickness. Blonde hair will have a higher tensile strength than black hair when at similar thickness. Blonde hair has more sulphur-sulphur covalent bonds than black hair. Hair contains the protein keratin, which contains a large proportion of cysteine with S-S bonds. The disulphide bond is one of the strongest bonds known anywhere in nature. The cross-linking by disulphide linkages between the keratin chains accounts for much of the strength of hair. Blonde hair has more of these bonds therefore blonde hair will have a higher tensile strength and elasticity levels. Null Hypothesis There will be no difference in tensile strength between black hair and blonde hair of similar thickness. Blonde hair having more sulphide bridges will not mean that blonde hair has a higher tensile strength than black hair. Background Knowledge Hair has a very high tensile strength. It can hold up 60kg of weight before breaking. This high strength is due to its structure. Hair is made of the fibrous protein keratin. Figure 1 shows keratin molecules are made up of three helices. They are held together by strong covalent bonds called sulphur bonds. Eleven of these molecules group together to form a micro fibril. Then, hundreds of micro fibrils join together to form a single hair. Hair is made of cells called epithelial cells which are arranged in three layers. The inner most layer is the medulla, the middle layer is the cortex and the out layer is the cuticle. The medulla is mainly soft keratin and the cortex and cuticle are mainly hard keratin. This structure has great strength. The cuticle, the outermost layer, is where you find a lot of the protein keratin. The cortex is the thickest middle layer, providing strength and defining colour of hair. The cortex also gives the hair its elasticity and flexibility. The medulla, central core, gives hair its strength and breadth. The structure of keratin is maintained by numerous sulphur to sulphur covalent bonds. Keratin contains high concentrations of the amino acid cysteine. Every Cystine unit contains two cysteine amino acids in different chains which have come to lie near to each other and are linked together by two Sulphur atoms, forming a very strong chemical bond known as a disulphide bridge. Many disulphide bonds form down the length of the keratin chains, joining them together like the rungs of a ladder. The disulphide bond is one of the strongest bonds known anywhere in nature. This cross-linking by disulphide linkages between the keratin chains accounts for much of the strength of hair. A suitable amount of Sulphur Bridge is important in enhancing the elasticity of hair due to the strength of the disulphide bond. Within each hair bonds of a different kind, called hydrogen bonds also link the keratin chains. There are far more hydrogen bonds than disulphide linkages. The hydrogen bonds are much weaker than the disulphide linkages and more easily broken, and give hair its flexibility. Hydrogen bonds are broken apart when the hair is wetted, and form again when the hair dries. Hair used for the investigation must not be ‘damaged’ in any way, i.e; should not be dyed/coloured, permed, straightened, etc. The hair also must not be curly. I will be only looking at naturally straight hair for this investigation. Permed and dyed hair cause severe damage to hair by reducing and breaking disulphide bonds between protein amino acids (which keep the hair strong) and they change the chemistry of hair by altering the protein rich internal structure of the fibre. In perming, a mild reducing agent is used to break the sulphur bonds. The helices are unwound and the hair is styled. A gentle oxidising agent (usually hydrogen peroxide) is treated to the hair to make the sulphur bonds reform. This results in a ‘permanent wave’. (Figure 3 shows the breaking and reforming of sulphur-sulphur bridges can produce permanent changes in the shape of protein molecules). Permed hair has only 90% of the original disulphide bonds, which leaves hair weaker than before it was permed. Heat (like from hair straighteners) disrupts the structural bonds (particularly weak Hydrogen bonds) enough to give hairs wounded around a roller some temporary curly aspect. However, this effect can be easily abolished by an increase in humidity or contact with water. Longer lasting permanents use chemicals such as thioglycolic acid to disrupt the disulphide bonds. Hairs to be tested with should not have their disulphide bonds damaged/broken or our hypothesis will become invalid even before the investigation takes place. Variables To Control†¦(keep the same) To investigate†¦(measuring/changing) Hair MUST NOT be: Tensile Strength (masses applied on hair) co loured/dyed Thickness of hair/colour of hair straightened (by applying heat) permed (by applying heat) curly (naturally) from the same person Hair MUST be: black or blonde straight (naturally) from the same age group Equipment 2 X Clamp stand – to hold everything upright 2 X Clamp – to hold paperclip/hair and ruler 100cm ruler – to measure how far hair stretches before it breaks (tensile strength) 2 X paperclip – to hold hair and mass 10kg masses with holder – to put tension on hair Selotape – to hold loop of hair in paperclip 15 pieces of black hair – to compare 15 pieces of blonde hair – to compare Micrometer – to measure hair thickness Method 1. I will first take five pieces of hair randomly from six different people. Three of these people should have black hair and three should have blonde hair. My total numbers of hair should be fifteen black and fifteen blonde. Hair samples should be taken from six different people to make sure that a fair and accurate test takes place. For example if all fifteen black hairs were taken from the same person, it could just mean that that person had thicker hair than normal thickness of black hair. This would make my results invalid. I will take all hairs from the same age group (my age group, 17-18), to erase the ‘age of hair follicle’ variable when comparing its tensile strength. 2. I will set up the micrometer to measure each hair thickness by placing hair under lens and measuring its thickness using a shown scale. I will record each thickness in an appropriate table. 3. I will place a black hair and a blonde hair of similar thickness side by side. This will be done to compare tensile strength of hairs of similar thickness. 4. Equipment will be set up as shown in Figure 5, (below) to start investigation. The hair will be carefully put in. The meter rule should be touching the bottom of the clamp stand with 0cm at the top and 100cm at the bottom. I need to make sure the hair can not slip out of the paperclip from the bottom or the top. Everything must be secure. The length of the loop of hair formed should be similar as with all hairs being tested. The weight should not be added until the rest of the equipment has been set up accurately. 5. Once the hair is set up in with the equipment, I will measure how far down the hair is on the meter rule. (Look at Figure 4, for assistance). I will record this reading in a table similar to Table 1. 6. A mass of 10kg will be placed on the paperclip at the bottom only after first measurements have been taken. 7. I will add the masses slowly so when the hair breaks I have a better view of the length of the hair. 8. When I see the hair break I will record its maximum length in my table and the weight in kg applied on hair at that point, when it reached its maximum elasticity. 9. I will repeat this whole process for all the blonde hairs and the black hairs. I will do the hairs of similar thickness after one another. For example; a blonde hair of thickness x would be measured first than a black hair of thickness x would be measured. There will be six people in my group including me. Each person will test five hairs each. Hair B1 B1 B2 B2 B B B B no. length bfr W app length bfr breaking length stretched bfr breaking max W app bfr breaking (cm) (cm) (cm) 2 minus 1 (kg) 1 2 Statistical Test I will use the t-test because I am looking for a difference of tensile strength in black and blonde hair. I will be using actual measurements (e.g. weights), and will have a large data set (30 pairs of data). I am comparing two sets of data. Investigating the factors affecting tensile strength of human hair Implementing: (Skill B) Modifications * Four different colours of hair need to be used; to increase range of results and to make my conclusion more reliable. Ginger, Blonde, Black and Brown hairs will be used. * 30 strands of hair will be used for each colour. 5 hairs from 6 people for each colour will be taken. * An eyepiece graticule will be used to measure hair thickness. Similar thickness of hairs will be compared. * Girls’ hair will be used. There are two reasons for this: a) Girls have longer hair b) Hormones may affect hair strength. Girls and boys may have different hormones. * There should be a 10cm (100 mm) gap between each paperclip. (Figure 5). * A 10g weight must be used each time. * I will need to modify my Hypothesis and Null Hypothesis because instead of comparing just two colours of hair I am now comparing four different colours of hair. Hypothesis There will be a difference in tensile strength between brown, blond, ginger and black hairs of similar thickness. Blonde hair (lighter coloured hairs) has more sulphur-sulphur covalent bonds than black hair (dark coloured hairs). Hair contains the protein keratin, which contains a large proportion of cysteine with S-S bonds. The disulphide bond is one of the strongest bonds known anywhere in nature. The cross-linking by disulphide linkages between the keratin chains accounts for much of the strength of hair. Lighter coloured hair has more of these bonds therefore lighter coloured hair will have a higher tensile strength and elasticity levels. Null Hypothesis There will be no difference in tensile strength between brown, blonde, ginger and black hair of similar thickness. Lighter coloured hairs having more sulphide bridges will not mean that lighter coloured hairs have a higher tensile strength then dark coloured hair. * Now that I am not comparing just two sets of data I can no longer do the T-Test. I am comparing four sets of data. My data will be categorical. There is a simple statistical test which looks at the difference between observed and expected values and relates them to a probability level, thus making it possible to identify how likely it is that the values are significantly different. This test is called the Chi squared test. Precautions to ensure reliability * We are assuming ethnic background does not affect our results. It will not cause a massive variation in our conclusion. * All hair samples must be taken from 16-18 year old females. * 6 different samples must be taken for each colour of hair. * Make sure all equipment is set up; ensuring the strand of hair is fastened to the shown equipment correctly. (Figure 5). * Each hair is tested five times, so I am repeating the experiment, to make my results reliable and more accurate. Results (My own (raw data) results will be highlighted in dark red on tables 2, 3, 4 & 5). (The letter ‘B’ is used in my results to show where the hair broke). Investigating the factors affecting tensile strength of human hair Analysing: (Skill C) Calculations Strength is determined by the amount of stress a hair can withstand without breaking. To work out the strength of each hair I calculated the stress applied to each when breaking. To do all the calculations I used the following formulas: 1. Force (N) = Mass (g) X 0.001 X 9.8 E.g. 10 x 0.001 x 9.8 = Force (N) Force = 0.098N 2. Cross Sectional Area (à ¯Ã‚ ¿Ã‚ ½m2) = ?r2 E.g. 3.14 x 26 x 26 = Cross Sectional Area (à ¯Ã‚ ¿Ã‚ ½m2) Cross Sectional Area = 2122.64à ¯Ã‚ ¿Ã‚ ½m2 3. Stress (Nm-2) = Force (N) / (Cross Sectional Area (à ¯Ã‚ ¿Ã‚ ½m2)/1000000) E.g. 0.098 / (2122.64/1000000) = Stress Stress = 46.16892172 (Nm-2) 4. Strain = Extension (mm) / Original Length (mm) E.g. 32 / 100 = Strain Strain = 0.32 The tables on pages 14 to 36 show how I calculated my values to do the statistical test. Discussion Melanin molecules are proteins, which are produced at the root of each hair. The more melanin in your hair, the darker it will get. An amino acid called tyrosine is converted into melanin so the hair will have colour. First, the body’s blood vessels carry tyrosine to the bottom of each hair follicle. Then, in this ‘melanin factory’ tyrosine is used as the raw material for the production of the natural melanin that is the colour in hair. In short, natural hair colour depends upon the presence, amount and distribution of melanin, a natural pigment found in the cortex. All natural hair colours are created from two types of melanin. Eumelanin = black pigment Pheomelanin = red/yellow pigment Mixed melanin’s = when both eumelanin and pheomelanin mix together inside one melanin granule. The natural colour of the hair is decided by: a) What type of melanin is in the hair b) How much melanin is in the hair c) How closely packed or scattered the melanin is within the cortex. The type of melanin and the size of the granules determine whether hair will be brown, blonde, ginger or black. The amount of melanin and its distribution determine how dark or light the hair colour will be. Black hair is created from granules full of eumelanin densely packed in the hair’s cortex. Brown hair, depending on its cool or warm tones and its darkness or lightness, is created either from granules filled with eumelanin and more sparsely distributed along the cortex than those of black hair, or granules filled with a blend of mixed melanin’s. The red/yellow pheomelanin is believed to cause the warm, golden, or auburn tones found in most brown hair. Blonde hair has a very low melanin content. And while scientists have not yet determined which is dominant, it is believed that eumelanin creates blonde hair. Melanin in blonde hair is so sparse that what we actually see is the colour of the hair fibre itself, keratin, which is a pale yellow, off-white shade. Granules filled with pheomelanin create Ginger hair. The pheomelanin in ginger hair is less densely packed in its granules. Its shape is somewhat more irregular than its black counterpart, eumelanin. It is slightly rounder and more spread out. From my results I found out that brown hair needed the greatest amount of force to break. Blonde hair needed the least amount of force to break. Black hair was second strongest and ginger hair was third strongest. The order of strength (from my results) of hair is as follows: Brown, Black, Ginger, and then Blonde. Brown hair stretched the most before breaking. Blonde hair stretched the least before breaking. Black hair stretched the second furthest and ginger hair stretched the third furthest. The order of length of hair stretched (from my results) before breaking is as follows: Brown, Black, Ginger, and then Blonde. Brown hair experienced the highest strain before breaking and blonde hair experienced the lowest strain before breaking. The order of strain experienced by hair (from my results) before breaking is as follows: Brown, Black, Ginger, and then Blonde. Brown hair experienced the highest tensile stress value before breaking and blonde experienced the lowest tensile stress value before breaking. The order of tensile stress experienced by hair (from my results) before breaking is as follows: Brown, Ginger, Black, and then Blonde. Graph 1 shows the average force required to break the four colours of hair. From this graph I can see that brown hair required the greatest force to break. Black hair also required a large amount of force to break and so did ginger hair. Black hair only required a small amount of more force to break then ginger hair. The breaking force required for brown, black and ginger hair was quite similar. Blonde hair required much less force to break compared to the other colours of hair. This proves that the disulphide bonds in the blonde hair are not a big advantage for strength of the hair. The darker the hair the stronger the force required for the bonds in the hair to break. The darker the hair the more resistant it is to breaking when forces are applied. The darker the hair the higher concentrations of melanin present along the hair cortex. The same sort of pattern is seen in graphs 2, 3, 4 and 5. Graphs 2, 3, 4 and 5 show the extension of hair when masses are added. Blonde hair breaks the earliest and brown hair breaks the latest. Graph 2 shows brown hair. Brown hair requires about 120g to extend up to about 70mm before breaking. The graph follows a basic trend and there are no anomalous results. All results fit the line of best fit. Graph 3 shows blonde hair. Blonde hair requires about 80g to extend up to about 35mm before breaking. The graph follows the basic trend and most results fit the line of best fit. There is one anomaly, though. The extension should not increase and then decrease. It should keep on decreasing. There must have been an error in recording this result. The results in graphs 2, 3, 4 and 5 are all averages. To work out the blonde values in table 32, the results in tables 12, 13, 14, 15, 16 and 17 were used. There was only one value for the extension at 80g, in table 15. This value was smaller than the average of all the extensions in all six tables. This sample of hair should have broken at 80g not 90g. This did not happen. This may have been an error in not measuring correctly. Graph 4 shows ginger hair. Ginger hair requires about 100g to extend up to about 60mm before breaking. The graph follows the basic trend until it gets to 55g point. From this point onwards the hair length increases and decreases dramatically. This should not happen. The reason why this happens is described above with the blonde hair. It is an error in measuring. Graph 5 shows black hair. Black hair requires about 140g to extend up to about 65mm before breaking. This graph is perfect. There are no anomalies. All points meet the line of best fit accurately. Graph 6 shows the average stresses and strains experienced by each hair colour. All four hair colours are plotted on the same graph so they can be easily compared against each other. Brown, blonde and ginger hairs do not follow the normal trend. The stresses and strains for these three should continue to increase. Tables 57, 58, 59 and 60 show where the stress and strain values came form. The results are like this because when the stress and strain values were calculated the average extensions were used, which had a few faults, as describe above. Graphs 7, 8, 9 and 10 show clearly what is happening to the stress-strain curves. Graph 7 shows one anomalous result. It has a high stress and strain value. Graph 8 also shows only one anomalous result. These two graphs show the basic trend. Graph 9 shows the normal trend until the stress value gets to 150Nm-2. Then it decreases and goes back on itself. This should not happen. The reason for this is explained above. There is an error in the extension averages. Graph 10 shows no anomalies. Graphs 11, 12, 13 and 14 show modified values for stress and strain in all colours of hair. Graph 11 shows the modified stresses and strains for brown hair. This graph does not bend backwards and the stress and strain values do not decrease. Graph 12 shows the modified stresses and strains for blonde hair. This graph does not show values of stress and strain decreasing. Graph 13 shows the modified stresses and strains for ginger hair. This graph has changed a lot. It reads much clearer. Stress and strain increases throughout. This is exactly what the graph should look like. Graph 14 is the same as graph 10. It did not need any modifications. The toughness of a hair is measured of its resistance to break. A lot of energy is required to break a tough material. Finally, the strength of a material (or ‘tensile strength’) is the greatest tensile stress it can undergo before breaking. Hair is an elastic material; it can stretch to a certain maximum point (elastic point) before breaking. The largest tensile stress that can be applied to a material before it breaks is known as its ultimate tensile stress (UTS). This value is sometimes referred to as the materials breaking stress. Graph 7 shows the stress-strain points for brown hair. Graph 11 shows a modified version of this. The UTS for brown hair is 359.03. Graph 8 shows stress-strain points for blonde hair. Graph 12 shows a modified version of this. The UTS for blonde hair is 125.48. Graph 9 shows the stress-strain for ginger hair. Graph 13 shows a modified version of this. The UTS for ginger hair is 286.58. Graph 10 shows the stress-strain points for black hair. Graph 14 shows a modified version of this. The UTS for black hair is 158.31. Overall I can see that brown hair was the strongest. This was not expected. I expected black hair to have the highest tensile strength, as it had a higher density of melanin along the cortex. Blonde hair turned out to be the one with the lowest tensile stress. Ginger haired people have a high density of the pheomelanin pigments in their hair fibre. Those who produce virtually no eumelanin have a red to orange colour depending on the density of the pigment in the hair fibre. Red haired people who have a greater relative proportion of eumelanin production have a deeper red to red brown colour. Ginger hair also should have a high tensile strength. This is what I saw in my results. Black hair should also have a high tensile strength. My results showed black hair to have high tensile strength but not the highest. There are other ways in which hair tensile strength could have been measured. Hair products like shampoos have an effect on hair tensile strength. They are now designed to change hair strengths. Different makes of hair shampoos could be used. Strength could be measured in a similar way to how I measured it. A control will be also be needed, with hair with no products added. These modifications in Graphs 11, 12, 13 and 14 show what the stress strain graphs should look like. In Graphs 7, 8, 9 and 10 the lines should not bend backwards. Statistical Test I will be using the (Chi squared test) X2. The formula for the Chi squared test is as follows: X2 = ? [(O – E) 2 /E] O = Observed value E = Expected value The ((O – E) 2) part of the formula considers the size of the difference between the observed and expected values. This difference could be either positive or negative. To avoid the mathematical problems associated with negative values, the difference is squared. The (E) part of the formula relates the size of the difference to the magnitude of the numbers involved. The sigma (?) ‘sum’ symbol is required because there is not just one pair of observed and expected values, but several (in this case four). By taking all the observed values of stress from tables 57, 58, 59 and 60, I can work out the expected value for each hair colour. I can then place these values in a table and work out the value for X2, using the chi squared formula. E = ( OBrown + OBlonde + OGinger + OBlack ) / 4 E = ( 297.3 + 121.5 + 246.7 + 158.3 ) / 4 E = 205.95 Brown Blonde Ginger Black O 297.3 121.5 246.7 158.3 E 205.95 205.95 205.95 205.95 ( O – E ) 91.35 -84.45 40.75 -47.65 ( O – E ) 2 8345 7132 1661 2271 (( O – E ) 2) / E 40.519 34.629 8.063 11.025 X2 = 40.519 + 34.629 + 8.063 + 11.025 X2 = 94.235 To calculate the degrees of freedom to be used can be found as follows: * Number of categories minus 1. In this case: 4 – 1 = 3 The critical value (taken from critical values for the Chi squared test) at 3 degrees of freedom is 7.81 (at the 5% level). The test statistic (X2 = 94.235) is greater than the critical value (C.V = 7.81, at the 5% significance level). We therefore can reject the null hypothesis and state there is a significant difference between the observed a Investigating the factors affecting tensile strength of human hair Evaluating: (Skill D) Limitations * The selotape holding hairs in the paperclip at the top and at the bottom could have interfered with the tertiary structure of the protein, keratin. This could have increased or decreased the bond attractions in the hair to cause the hair to have a high or low tensile stress. This would make my results unreliable. The hairs showing higher tensile stress may just be showing how sticky the selotape is and how strongly it is holding the hair structure together. This though, would affect all my results, as all hair samples had selotape on them to hold them together at the top and at the bottom. So, this limitation would affect all hairs making it a very weak limitation. My conclusion will not be affected as this limitation affects all hairs. * The time in between weights were added is another limitation. When each weight was added the hair stretched. But when there were a lot of weights on hair, the hair stretched quickly and then the length was measured. After I finished measuring the hair had slowly stretched a little bit more. So the measurement was wrong. When the next weight was added extra extension was added onto the new extension. My results were affected by this because some extensions were false making some data imprecise. Therefore, my conclusion will be invalid, because some hair samples could have broken at lower weights if I had waited for the hair to stretch, very slowly until it broke. There needed to be a time limit in which I had to record the extension of the hair, before adding the next weight to the hair. * The eye piece graticule can be a limiting factor. Different people measured hair thickness and recorded it to what they felt the thickness ought to be according to the scale. It was not very clear to see how thick the hair was, as the hair was faded under the microscope at all magnifications and the outline was difficult to see. This could affect my results as the thickness of hairs was used to calculate the cross sectional area of the hairs, which was then used to calculate the tensile stress experienced by the hair. This could make my tensile stress values incorrect. My conclusion therefore could be affected; by making out that a certain coloured hair had a higher tensile stress than another coloured hair, when really it shouldn’t have. This would make my conclusion unreliable. * There were different shades of hair colour, for example, there were light brown hair colours and dark brown hair colours. It was sometimes hard to distinguish between brown and blonde. This was the same for blonde hair. This would have an affect on the reliability and precision of my results making the accuracy of the strengths of different colours of colours of hair inaccurate. There should have been a certain shade of colour of hair (same amount of melanin in each brown hair) used for each colour sample. My conclusion will be imprecise because brown or blonde hair shades could cause incorrect results and make my conclusion incorrect. * The 10g mass is a limitation as the hair could break at lower masses than they actually did, for example a hair that broke at 50g could have broken at 41g, but I wouldn’t know that as I only used 10g masses. So, I got false readings implying the hair is stronger than it actually is. If smaller masses were used my results would be much more accurate to make my conclusion reliable. This limitation could cause my conclusion to be invalid, causing the hairs strength and point on breaking higher or lower than it actually is. Conclusion After doing my statistical test I can reject my null hypothesis and accept my hypothesis and say that brown, blonde, ginger and black hairs differ in tensile strength. I have proved this difference in my calculations, mainly in graphs 1 and 6. From my results I can see that darker coloured has a higher tensile stress compared to lighter coloured hairs. In my hypothesis I said that lighter coloured hair would have a higher tensile strength than darker coloured hair, due to lighter coloured hair having sulphur-sulphide bonds, which are very strong. I have disproved this. Through testing all four colours of hair I can see that these strong sulphur bonds do not reflect any tensile strength qualities. Lighter coloured hair does not have an advantage over dark coloured hair when it comes to tensile strength. It mainly depends on the type of melanin the hair contains. The denser the melanin quantity is the stronger the hair.
