Applied Statistics for Finance and Economics Project

Applied for Finance and Economics - Statistics Project Example The two will guide the analysis of the rest of the analysis. The first section of the project focuses on the brief description of the two variables representing the log return series. It will apply various statistical approaches including the descriptive methods and graphical methods. Consequently, it will conduct the test for normality to ascertain whether the mean difference and median difference really exist, as well as confirming the randomness and volatility of the stock distribution. The project culminates in the analysis of the capital calculation through the Capital Asset Pricing Model (CAPM) as well as the OLSE (Estimation of the Ordinary Least Squares, in order to test relevant observations concerning the Bata estimation. The figure above shows the summary of the descriptive statistical techniques, for all-important information on the log return on stock value series as well as the log return value of the sap series (Standard and Poor). This is based on the 252 observations forming the entire dataset. The log return of the stock series (lsap) shows a mean of the distribution to be 7.14367. It also gives the standard Deviation of the distribution to be 0.0502348 while the variance of the distribution is 0.0502348. In this regard, the standard deviation of the sample mean can be calculated as 0.0953768 / √252 = 0.006008. The Skewness of the distribution is a positive value of 0.148524 while the nature of Kurtosis is described by the positive coefficient of 2.175841. This according to Tinsley and Brown (2000), indicates a right-skewed distribution with a positive skewness. The lowest quartile is 3.462919; the median value is 3.615367 while the highest quartile is 3.827336. The log return of the stock series (lsap) shows a mean of the distribution to be 3.62903. It also gives the standard Deviation of the distribution to be 0.502348 while the variance of the distribution is 0.0025235. In this regard, the standard

Change management - Essay Example Change management could either be individual change management or organizational change management. The individual change management consists of three steps – unfreezing, adapting to change and refreezing. The in the first stage the existing mind-set has to be released and then the confusion and transition starts. In the third stage the new mind-set is crystallized and the individual’s comfort levels returns to the previous level. There has to be awareness why change is needed, desire to support and participate in the change, the knowledge how to change, the ability to implement new skills and behavior, and finally sustain change. Organizational change management requires processes and tools for managing the people side of the change at an organizational level. The management needs to first detect the trends in the macro and micro environment. Change in an organization can be due to downsizing, redundancy, change of management through mergers and acquisition, change due to expansion, and most important due to the advancements in technology. According to Worrall, Campbell & Cooper (1999) redundancy is the most evocative and fear inducing form of organizational change for many workers. Landale (2004) believes motivation is the key to empower the staff and get the front line managers to take collectively responsibility. A study by Patterson et al., (1997) confirmed that management of people was more important than the combined effect of strategy, product, service quality, or even the manufacturing technology or the expenditure on R&D (cited by Gollan, 2006). There is a definite relationship between employee performance and their attitude. Communication organizational aims and objectives are important. Difficult issues can be resolved through discussions. Honesty, trust, openness, employee participation, all helps to achieve high motivation among staff. Recognition of staff through promotional material also helped to

Ecology - Research Paper Example The transitions did not follow a successive order but were rather random for each squirrel. In addition, it became evident that a relationship exists between the behavioral transitions. From the analysis, the behavioral changes appeared to be the results of chance and were very random. The highest transition frequency was between the food searching behavior and food handling. The lowest frequency occurs in vigilance behavior and food searching. The animals must strive to strike a balance between safety precautions and food searches. For the balance to occur, squirrels have to set the priorities right. It is critical for them to determine when the urgency for security must surpass the urgency for food. Introduction The Eastern Gray squirrel’s main habitat is the eastern North America and parts of Canada (Makowska and Kramer 2006). This species relies on seeds, nuts, acorns, beechnuts, butternuts, and hickory nuts for food. These squirrels usually remain in their dens and nests during winter. The Gray squirrel must avoid getting into the way of its multiple predators. These predators include hawks, owls, raccoons, and snakes. Socially, these squirrels value relationships and have close associations within their communities. This species of squirrels exhibits unique behaviors when feeding. These squirrels have many predators and have to stay wary of while searching for food. This is the reason why squirrels exhibit multiple behavior changes in their search for food, as they have to strike a balance between feeding and remaining secure. Many scientists have tried to decipher the behavioral patterns of the squirrels in the venture for the search of food. Numerous ecologists have been striving to explain why these behaviors result. This experiment sought to establish the different patterns portrayed during the squirrel’s search for food (Parker and Nilon 2008). Prior to this experiment, we predicted that the gray eastern squirrel portrays several foragi ng patterns. In addition, we hypothesized that there was a relationship the transition from one pattern to the other. Specific predictions suggested that there was vigilance behavior that led to food searching. There was also a possibility that food-handling behavior would precede vigilance behavior. Methods In this experiment, we observed squirrels for duration of fifteen minutes. We used focal fallows to observe the behavioral patterns of the squirrels. After observation, we tallied the frequencies of transitions indicating. Finally, we used chi-square test to determine the relationship between the transition behaviors. Results Statistical analysis of the data derived from tallying the observations presented the data available in the table 2 in the figures shown. The graph in figure shows the number of squirrels that exhibited different transition behaviors. The highest frequency occurred between food searching and food handling. The transition from vigilance behavior to food sear ching presented the lowest frequency. The squirrels also switched from vigilance behavior to food handling at a remarkable frequency. Only in few occurrences did the squirrels exhibit a transition from either vigilance or food handling behavior to engage in social behavior. It became evident that the squirrels did not exhibit any transition from social behavior to food

The meaning of the marine NCO - Essay Example War is usually fought by trained personnel who are either expert in ground combat, air combat or water combat. However the USA Marine Corps is a special unit that is a maestro both in ground and water combat. In this sense they might be termed as the amphibians as powerful as a tiger lurking its prey on ground and as vicious as a crocodile waiting silently beneath the water without a hint that its probable prey could have catch. United States of America has a rich and engrossing military history. Over the centuries they have not only protected their home land rather came into rescue for several times to other nations well. The two of the prime example might be the first Great War followed by the second one within a span of quarter of a century. Such aggression and military success by no means qualifies the country as war monger, but war is an evil necessity and at times to restore peace or to save the world from evil dictatorship dedicated to wards military regime instead of fostering democracy; war cannot be avoided. The effort of the USA military can best be classified under these two headings one to restore global peace and the other to tame the evil dictators who came with a dream to rein the entire world through force of military not by the power of love. The USA armed force has several sectors, each dedicated to its own cause and entrusted with their specific responsibilities. The entire armed force of USA might be sub-divided into four parts namely, US Army, US Navy, US Marines and US Air Force (Wisegeek, 2013). The term USA Marine Corps brings peace to the heart of each American people and runs a chilly wave along the spine of all the enemies of United States of America. The first question that hover the mind of a researcher is what was the need for the USA Congress to initiate a new division of armed force? The Marine Corps started as an infantry division within the Navy with a view to protect the ship from any mutiny and

Chinese Mythology Essay Example for Free

Chinese Mythology Essay Mythology is a collection of myths or the study of ancient traditional stories of gods or heroes, giving an explanation to an unexplained event. For Plato, the fist known user of the term, muthologia meant know more than the telling of stories (Kirk 8). Mythology is an important aspect to the world, today. Through the study of myths help us develop an idea of what the cultures were like. It includes hints that exhibit how they lived their lives. Myth is its serious purpose and its importance to the culture (Lansford 1). Every culture has its own myth that explains about the nature of that particular culture. The Chinese culture has been around for many centuries, its myths have accumulated into varies stories of gods and their culture. China is the worlds oldest continuous civilization (Cotterel 9). Evidence show the earliest Chinese civilization to be found around 1650 B. C. The beginnings of Chinese mythology, started around the Wei and Jin Dynasties. Influenced by alchemist ideas, Taoist and Buddhist superstitions, various writers created storied about their enigmatic surroundings. The beginning of the Chinese civilization is based on mythology. One of the creation myths is about the beginning of the world. In it, the world began as an egg and cracking open, the top of the shell grew to be the sky, the lower shell became the Earth, and in the middle stepped a man named Pan-gu. Mythology of the ancient Chinese is apparent through art, music and literature. Since, there is no explanation of how the Chinese civilization began; mythology has been a way of explanation to the Chinese culture and other cultures around the world, today. Chinese mythology, as with many other cultures, has many gods and goddesses that are in charge of various things. In the Ancient Chinese culture, there are gods and goddesses for every important aspect of the peoples life, even things as unlikely as the stove god and the door god. Other deities that were important to the Chinese people were the gods of the elements such as Chu Jung, the fire god, Lei Kun, the thunder god, the wind god, and the lightning goddess. Most of the element gods devoted themselves to punishing criminals and keeping evil spirits away. There were also important gods in charge of fields such as Kuan Ti, the god of war, Kuan Yin, the goddess of compassion, TShai-shen, the god of wealth and Tsao hsang, god of the hearth. Although there gods were very important to the Chinese people, one of the most important gods was Nu wa, the mother goddess. She was a compassionate goddess who created mankind and bestowed love and creation to them. She helped her people when they were in need, like when she created rice from her own milk and blood in order to feed her people. She was very humble and a modest goddess, not wanting credit for her benevolence. The gods and goddesses of Chinese mythology were basically deities that symbolized the good and just qualities that people should imitate in their everyday life. The basis of Chinese life was a belief in harmony and balance (Williams 20). The Chinese believed in harmony with nature, and sometimes honored the spirits with gifts, feasts, and rituals. The Chinese believed the souls of the dead returned (Williams 20), a concept of Buddhism. The family held Chinese society together (Williams 20). In China, many generations of families lived together, even in the same house, and the children were taught to respect and obey their elders (Williams 20). As in all cultures, men were ? superior to women in China. Parents believed they would become gods after they died, if they had a son (Williams 21). This belief was taken fiercely to the point that the parents would kill a newborn female. A custom that the upper-class women followed was of foot binding, which was believed to make the foot appear tiny, since the culture considered small feet feminine and delicate. The most important festival in China was the Chinese New Year, it is held in the spring of each year. During this festival, offerings were given to the sprits. In China, the color white is considered the mourning color and the children showed respect for dead parents by fasting and wearing thick clothes (Williams 21). Most beliefs and customs of the Chinese culture appear from the religions of Confucianism, Taoism, and Buddhism. The Chinese culture has a long history of beliefs and customs, which are used by the generations before and now. It is highly unlikely that the generations to come would not be following the same beliefs and customs of the ancient Chinese. The origin of religion goes back to prehistoric times when the earliest people of China sought answers to the same basic questions that have baffled primitive men over the world: what is the unseen force that brings darkness and light, winter and summer, drought and rain, life and death; what must men do to appease this force? (Schafer 57) Ancient China has three main religions Taoism, Buddhism, and Confucianism. Confucius was concerned mostly with laws made by people, and whether people were naturally good or naturally evil. In contrast, the followers of Lao-tzu believed people were guided by universal laws, not human ones. This was the basis of Taoism (Williams 18). Taoists tried to live a life of simplicity and meditation close to nature. Taoism was mystical and influenced by ancient Chinese folk religion. Its followers used magic as well as prayer and diet to seek eternal youth (Williams 19). Taoists were peaceful people who generally lived peaceful lives. Buddhists follow the teachings of Buddha (born 563 B. C. ), a north Indian prince who devoted his life to a search for personal peace, or enlightenment. The name Buddha means enlightened one. He believed that by giving up worldly desires, such as for fine food and clothes, a blissful state called nirvana could be achieved. In nirvana there was freedom from sorrows of the world. Indian belief as that time held that people were reborn many times. Persons who had lived badly in former lives might be born in an animal or insect form. Buddha said that by reaching nirvana, this endless cycle of rebirth could be broken (Cotterell 27). Buddhists follow an eight-fold path, this is like a code by which they live. Confucianism came in earlier than Taoism and Chinese Buddhism. The so-called Confucian classics were, in fact, complied long after the death of Confucius by disciples of his disciples, and were edited and interpreted in Han times by government scribes; but they purport to reflect the views of the great sage of antiquity on history, religious rites, morals, and standards of behavior. The state officers of Han times accepted these interpretations and associated them with the standardized pagan nature worship of state cult as a part of the acceptable way of life for a Han gentleman. We in the west sometimes call this way of life, which includes both reverence for the ? ancient books and the ? ancient gods, ? Confucianism (Schafer 60-61). Confucianism flourished in China as so did the other religions. The Chinese were inquisitive people, always inventing and always wondering how things worked. It is only logical for them to generate religions that explain how life is and how it will be in the afterlife. In Chinese mythology, myths and legends deal with aspects of human nature, human relations and social life (Owens). Chinese myths use human traits, like emotion, to convey lessons. The myth on the creation of man clearly depicts the basics of a Chinese myth. After Pan-gu, creator of the world, died and his body transformed into different elements of the Earth, Nu wa, the dragon goddess, came down from heavens and admired Pan-gus creation. In order to honor Pan-gus sacrifice to the Earth, Nu wa decided to create humans. She started to make them out of yellow clay, but since it took much of her strength, she dipped a rope into the mud and when she took it out, the drips became people. Her clay and mud people were not alive, so her heart took pity and she breathed her divine breath into them. She also whispered thoughts of love and creation into their ears and told them to reproduce. The people made of yellow clay became the rich and the people Nu wa made of mud became the poor. This myth explains many aspects of human life. It explains how the social classes came to be and also human emotions. Nu wa shows human emotions like honor, when she was determined to let Pan-gus death not be in vain; in compassion, she breathed her divine breath into each and every human. This myth represents human relations because Nu wa put ideas of love and procreation into the human races mind. These Chinese myths explain how the good and bad came to be and how a person should live a happy a fulfilling life. Mythology is not a subject that should be ignored. It is an important subject that should be learned and understood by all cultures so that as a world, we can come to understand each other better. The first step in hatred is fear. Fear of the unknown can generate more hate than anyone could possibly fathom. If everyone became educated about other culture, there would be little to know unknown, and there would probably be less hate in the world. Mythology, the study of myths, gives people an insight to others dreams, hopes, and their fears. We all have hopes, dreams, and fears. By learning about other cultures hopes, dreams, and fears we can feel more connected to each other and reach out. Mythology is a key element in keeping peace without shedding blood.
