The History of the Olmec Site of La Venta
The History of the Olmec Site of La Venta The Olmec capital of La Venta is located in the city of Huimanguillo, in the state of Tabasco, Mexico, 15 kilometers (9 miles) inland from the Gulf coast. The site is perched on a narrow natural elevation approximately 4 km (2.5 mi) long which rises above the wetland swamps on the coastal plain. La Venta was first occupied as early as 1750 BC, becoming an Olmec temple-town complex between 1200 and 400 BC. La Venta was the primary center of the Olmec culture and likely the most important regional capital in non-Maya Mesoamerica during the Middle Formative period (approximately 800-400 BC). In its heyday, La Ventas residential zone included an area of ~200 hectares (500 acres), with a population numbering in the thousands. Architecture at La Venta Most of the structures at La Venta were built of wattle-and-daub walls placed atop earthen or adobe mudbrick platforms or moundsà and covered with a thatched roof. Little natural stone was available, and, apart from the massive stone sculptures, the only stone used in public architecture was a few basalt, andesite and limestone foundational support or internal buttresses. The 1.5 km (~1 mi) long civic-ceremonial core of La Venta includes over 30 earthen mounds and platforms. The core is dominated by a 30 meter (100 foot) high clay pyramid (called Mound C-1), which has been heavily erodedà but was likely the largest single building at the time in Mesoamerica. Despite the lack of native stone, La Ventas artisans crafted sculptures including four colossal heads from massive blocks of stone quarried from the Tuxtla Mountains approximately 100 km (62 mi) to the west. The most intensive archaeological investigations at La Venta were conducted in Complex A, a small group of low clay platform mounds and plazas within an area of about 1.4 hectares (3 acres), located immediately north of the tallest pyramidal mound. Most of Complex A was destroyed shortly after the excavations in 1955, by a combination of looters and civic development. However, detailed maps of the area were made by the excavators and, due primarily to the efforts of archaeologist Susan Gillespie, a digital map of the buildings and construction events at Complex A has been made (Gillespie, Gillespie, and Volk). Read more on Complex A at La Venta Subsistence Methods Traditionally, scholars have attributed the rise of Olmec society to the development of maize agriculture. According to recent investigations, however, the people at La Venta subsisted on fish, shellfish and terrestrial faunal remains until about 800 BC, when maize, beans, cotton, palm and other crops were grown in gardens on relict beach ridges, called tierra de primera by maize farmers today, perhaps fueled by long-distance trade networks. Killion (2013) conducted a survey of paleobotanical data from several Olmec period sites including La Venta. He suggests that the initial founders at La Venta and other Early Formative sites such as San Lorenzo were not farmers, but rather were hunter-gatherer-fishers. That dependence on mixed hunting and gathering extends well into the Formative period. Killion suggests that the mixed subsistence worked in the well-watered lowland environments, but that a wetland environment was not suited to intensive agriculture. La Venta and the Cosmos La Venta is oriented 8 degrees west of north, like most Olmec sites, the significance of which is obscure to date. This alignment is echoed in Complex As central avenue, which points to the central mountain. The central bars of each of La Ventas mosaic pavementsà and the four elements of the quincunxes in the mosaics are positioned at intercardinal points. Complex D at La Venta is an E-Group configuration, a specific layout of buildings identified at over 70 Maya sites and believed to have been designed to track movements of the sun. Archaeology La Venta was excavated by members of the Smithsonian Institution, including Matthew Stirling, Philip Drucker, Waldo Wedel and Robert Heizer, in three major excavations between 1942 and 1955. Most of this work was focused on Complex A: and the finds from that work were published in popular texts and La Venta quickly became the type site for defining the Olmec culture. Shortly after the 1955 excavations, the site was badly damaged by looting and development, although a brief expedition did retrieve some stratigraphic data. Much was lost in Complex A, which was torn up by bulldozers. A map of Complex A made in 1955 formed the basis for digitizing the field records of the site. Gillespie and Volk worked together to create a three-dimensional map of Complex A, based on archived notes and drawings and published in 2014. The most recent archaeological studies have been undertaken by Rebecca Gonzlez Lauck at the Instituto Nacional de Antropologà a e Historia (INAH). Sources Clark JE, and Colman A. 2013.

Are International institutions effective in solving collective Research Paper
Are International institutions effective in solving collective Problems Case study of Treaty on the Non-Proliferation of Nuclear Weapons and North Korea's Nuclear crisis - Research Paper Example A plan offered by the United States in 1946 also proposed that all nuclear arms and technology come under international control and ownership. However, the post World War efforts did not seem to work out too well and it was later on that countries started to pledge allegiance to the NPT (Non Proliferation Treaty) which kicked off in 1968 and became effective in 1970. A list of around 190 countries are signatory to the treaty. The NPT rests on the premise that the non-nuclear nations would agree to never pursue any sort of acquisition of nuclear arsenal whereas the nuclear weapon state would share the benefits of it with the non-nuclear states. The treaty is reviewed for changes every 5 years and as of now, stands as being extended till an indefinite period. North Korea had the USSR as its strongest communist ally at the time of the cold war. When the cold war came to a close, Soviet Russia had weakened substantially. North Korea, that looked upon it as a security guarantee began to think that now it should itself do something to curb the situation. Therefore, in 1989 the United States, through its intelligence network, found that North Korea which had signed the NPT is in the early stages of building an atomic bomb. In 1992 North Korea allowed a team from the IAEA (International Atomic Energy Commission) to undertake visitors to its nuclear facilities. The inspections seemed to not go as expected and North Korea had blocked the commission from visiting some of its facilities. In 1994 an ââ¬Å"Agreed Frameworkâ⬠was reached between America and North Korea that stated that N. Korea would abandon its nuclear program and the U.S. would provide oil for electricity and better economic ties would be maintained .Also, the atomic plants w ould be replaced with light water nuclear power plants .However, the routine inspections would continue by the IAEA, However in late 2002, George Bush

Substance Abuse Counseling- Family Roles and Dynamics Assignment
Substance Abuse Counseling- Family Roles and Dynamics - Assignment Example For instance, in cases where parents are users of such substances like alcohol, the dependents always tend to follow suite, and especially for those whose parents were very prone to alcohol. A research conducted in the US found that almost half of all children (35.6 million) live in a household where a parent or other adult uses tobacco, drinks heavily or uses illicit drugs. Family wrangles and divorce have been a significant source of substance addiction and abuse. In a research conducted, it was found that children who were subjected to parental divorce can lead to a childââ¬â¢s risk to substance use. It was found that over 50% of teens whose parents had divorced were likely to drink alcohol than those who had both their parents (The National Center on Addiction and Substance Abuse at Columbia University, 2005). Members of family of substance abusers regularly live in constant fear that their flimsy surroundings could collapse. Those families affected by substance abuse are usually characterized by marital problems, increased exposure to diseases, child neglect or abuse, inconsistent childcare, exposure to crime, social isolation, childrenââ¬â¢s academic problems, domestic violence, shifting family roles, and financial difficulties. In financial problems, substance abusers are exposed to long-term unemployment, injuries/accidents at work, and job instability; this puts their families under intense financial pressure (The National Center on Addiction and Substance Abuse at Columbia University, 2005). For instance, time spent assisting a substance abusing family member can minimize the time available for work and this ultimately minimizes family earnings. In another instance, substance abuse in a family increases the probability of divorce and unhappy marriages. It is suggested that substance abuse in a family can influence its quality. Poorer relations in a marriage are more likely in alcoholic men

Staffing and Training Essay Example for Free
Staffing and Training Essay As multinational firms globalise they must learn to co-ordinate efforts among an increasingly culturally diverse workforce and environment. Nowadays people tend to be very defensive of their cultural identity and caution by others has to be taken so that insult is not caused. Through the years success of Japanese organisations global strategies has encouraged American firms. Although many point out the advantages, cultural diversity may leads to conflict, misunderstanding and lack of cohesion. (Tung, [1993]) states that cross cultural training process, helps in the development of building relations between individuals or groups, especially individuals/groups with diverse cultural backgrounds. (Welch [1998]) defines cultural training as any form of guided experience helping people to live and work more contentedly in another culture. Such training encourages understanding about differences and acceptance of the multicultural work environment and helps create and retain effective work teams and expertise in dealing with multicultural management (Hartenian, [2000]) describes the multi-cultural workforce as a workforce that excludes no one, from top-level management to low-level employees. He sees the multi-cultural workforce has one of the main opportunities for an organisation. Although multi-cultural workforces are beneficial to organisations in relation to performance and profitability, they can be very hard to manage. According to (Hill, [92]) the key to managing multi-cultural workforces is the realisation that majority and minority cultures do not always share experiences. To solve this managers can adapt different strategies such as: developing programmes that promote awareness of different cultures, recognise common links among different ethnic groups and express concerns and confusions. (Hill [1992]) believes that if organisations use these strategies, economic benefits will be reaped. This may be easier said than done, (Harisis Kleiner, [1993]) argue that the implementation of such workforces are extremely difficult. They say that not only within American society and businesses but on a world wide scale there are widespread barriers. Such barriers include unwritten rules and double standards for success which are often unknown to women and minorities, stereotypes and their associated assumptions and lack of communication about differences. In global organisations it is essential that effective cross cultural training occurs in order to help individuals obtain both the knowledge and the tools needed to reduce misunderstandings and improper actions (Black Mendenhall [1990]) suggest that multi-cultural training provides individuals with greater self confidence and decreased narrow-mindedness about people from diverse cultures. In addition (Barlett and Ghoshal [1990]) also pointed out that establishing a multicultural training programme improved the companys ability to operate more efficiently in different cultural environments. Although many multicultural training programmes are undertaken to enhance cultural diversity they are not always successful. According to (Woods [1992]) a systematic approach should be taken towards training. (Woods [1992]) established a four step cycle: Firstly was to specify certain job task of individuals and assess the needs of the corporate culture. Secondly is the identification of training objectives. Thirdly was the establishment of the proper training content in which the following was used; sensitivity training, cultural awareness and orientation programs. In addition (Cox, [1993]; Gamio Sneed, [1992]; Tung, [1993]) introduced the communication competency program. In the final stage (Milkovich Boudreau [1991]) stated that training programs need to verify whether the training is successful in junior members of staffs performances at work. The cycle used was concerned with the effectiveness of the training, however, (Mendenhall Oddou [1986[ Tung [1981]) found factors that deterred individuals. These included lack of specialised trainers, cost and perceived lack of usefulness. Research carried out by (Gamio Sneed [1992]) found that the deterrence factors are of major importance. Take for instance the catering industry. Mangers in restaurants may blame high staff turnover rates on lack of multi-cultural training, therefore using these rates as the reason to ignore the need for training programs. (Jackson [1991]) believes that heterogeneity among team members contributes to high turnover rates within organisations. Researchers may find that the re lationship between cultural diversity and staff turnover is of major importance to all organisations. Hospitality researchers Results of this study have provided useful directions for future research in the area of multicultural training. Respondents in this study perceived more success in improving interpersonal skills than dealing with culturally diverse people because those skills are probably more easily observable and acquirable. A more rigorous research design is recommended before definitive conclusions about the efficiency of the training can be reached (Black and Mendenhall, 1990). Without identifying a baseline of knowledge and skills before starting the program, it becomes difficult to measure training effectiveness. Researchers can solve this problem by utilizing a pretest-posttest design with a control group, identifying two separate groups during pretest. One group would be tested before and after receiving the training. The other group would simply be tested twice once before and once after the program but they would not receive the training. By measuring both groups, training managers could fully assess the impact of the training program. Furthermore, the measurement of the training effectiveness needs to incorporate the trainees estimation about the program in addition to perceptions from directors of human resources. Alliger and Janak (1989) advocated that training needs to integrate two evaluation criteria: 1 Internal. For assessing how trainees feel about the training experience. 2 External. For estimating the changes in job behavior and organizational effectiveness (Milkovich and Boudreau, 1991). . Such training encourages understanding about differences and acceptance of the multicultural work environment and helps create and retain effective work teams and expertise in dealing with multicultural management. Full Text (2411 words) Copyright InfoWorld Publications, Inc. Apr 24, 2000 [Headnote] As the IT workforce grows more diverse, managers must improve awareness without creating inconsistency Diversity will have a significant impact on the hospitality industry. On one hand, diversity may cause problems, particularly in older, traditional organizations with a homogeneous workforce, including communication difficulties with supervisors and co-workers as well as with customers. Thus, group cohesiveness may be reduced by an increased cultural diversity among group members (Cox, 1993). The lack of understanding of different cultures may lead to ineffective management techniques in directing, motivating, and rewarding culturally diverse employees. On the other hand, diversity enriches a hospitality organization by adding new cultures, ideas, and alternative methods for solving problems.). What is not understood is what effects, if any, these changes will have on an organization and how it can respond in a proactive way to them. Recognizing the significance of managing diversity in the hospitality organization, Welch et al. (1988) suggest that developing cultural awareness in a company helps employees become familiar with different values, interpersonal interactions, and communication systems which must be understood for an effective multicultural working environment. Christensen (1993) emphasizes that organizations failing to acknowledge the full range of variety inherent in their employees and customer populations will have difficulty surviving . Restaurants need to have more thorough multicultural training programs, focusing on training goals which are practical and job-specific. Job result-oriented training goals, including increasing employee teamwork among culturally diverse employees and improving cross-cultural skills, must be a part of the training goals to encourage employee participation and eventually help in facilitating job performance in dealing with multicultural work environments. In addition, training methods should be more comprehensive rather than limited. As case 3 reported, minority mentor and advisory programs could be utilized to encourage full participation of ethnic minorities. These involvement efforts, with full support from upper management, would help change employees attitudes and lower barriers between diverse workers and promote ethnic minorities, and hopefully lead to less turnover generated from the feeling of isolation and difference. Furthermore, human resource directors may consider utilizing employees with multicultural experience. For instance, the company can hire managers who have hands-on experience with different cultures or language skills for efficient interaction with diverse employees and for multicultural training. These comprehensive training approaches can eventually generate productive training results and increase better understanding among employees from diverse cultural backgrounds. Hospitality researchers Results of this study have provided useful directions for future research in the area of multicultural training. Respondents in this study perceived more success in improving interpersonal skills than dealing with culturally diverse people because those skills are probably more easily observable and acquirable. A more rigorous research design is recommended before definitive conclusions about the efficiency of the training can be reached (Black and Mendenhall, 1990).

For estimating the changes in job behavior and organizational effectiveness (Milkovich and Boudreau, 1991). . In responding to the multicultural work environments and international scope of restaurant operations, the hospitality industry should provide proper training for line employees who require customer interactions during their routine jobs in addition to managers who deal with employee promotion and corporate culture. TRAINING Perlmutter identified three managerial attitudes toward international operations Managers with an ethnocentric attitude are home-country oriented. Home-country personnel, ideas, and practices are viewed as inherently superior to those from abroad and are used for evaluation purposes. A polycentric attitude is a host-country orientation based on the assumption that because cultures are so different, local managers know what is best for their operations. Managers with a geocentric attitude are world-oriented. Skill, not nationality, determines who gets promoted or transferred to key positions around the globe. This attitude attempts to maintain a balance between global standards and local discretion. A geocentric attitude can help management take a long step toward success in todays vigorously competitive global marketplace. complexity. Documentary programs. Culture assimilator.

There is a wealth of academic research studying the factors which may lead to greater success. Some authors suggest that greater attention up front to structural and partner characteristic dimensions will arrest the high failure rate (Parkhe, 1993). Recent research effort has been directed towards forwarding general prescriptions for managing the relationship once the alliance is under way Parkhe, A. (1993), Strategic alliance structuring: a game theoretical and transaction cost examination of interfirm cooperation, Academy of Management Journal, Vol. 36 No. 4, pp. 794-829. The work of Hofstede (1980), in particular, is considered the most comprehensive effort, involving analysis of a large scale questionnaire based survey of one large American corporation in 40 of its subsidiaries. Hofstede found that differences in national culture varied substantially along the four dimensions of uncertainty avoidance, individuality, tolerance of power distance and masculinity-femininity. Hofstedes work has frequently been used as a starting point to identify and model cultural clusters (Kogut and Singh, 1988; Ronen and Shenkar, 1985). Although the methodological approach has been extended to explore the effect of culture on international cooperation (Johnson et al., 1993; Graham, 1988) the difficulties of measuring and monitoring exchange processes have been noted. Indonesian culture, particularly Javanese and Sundanese culture (the latter from the region of Bandung) is very different from modern Western European and North American culture. Particular aspects of these cultural differences can affect the trust-building process. The case provides key episodes which illuminate these cultural trait differences and suggests methods to work within this cultural diversity. The critical involvement of stakeholders A key cultural dimension in SE Asian culture is the collectivist approach to business. This manifests itself in our case study through the critical involvement of stakeholders in the formation phase of the JV. The role of stakeholders and management of their interests is a key theme running through the paper. In particular, the case study suggests a need to systematically identify the power and interest of potential stakeholders and plan for and subsequently negotiate their roles and influence in the venture. These factors have led many Western companies to look for help and expert local advice through collaborative arrangements with ASEAN country partners. Market entry strategies have favoured equity JVs, which several ASEAN countries prefer in order to protect their own interests and ensure long-term growth (Lasserre, 1995; Mann 1996). The JV formation process: an analytical framework Lorange and Roos (1993) proposed a formation process model for JVs and strategic alliances which consisted of two areas of consideration; political and analytical and two phases of development; the initial and the intensive phase. This model has been modified and extended to create an analytical framework which derives from the Indonesian JV experience. The marketing and economic benefits from such a JV were apparent to Lucas at the time. Essentially the JV would provide abundant and highly skilled low-cost labour (with future joint product development a realistic possibility), made up of a loyal, dedicated and, importantly, reliable workforce with excellent proven machine tool skills and capabilities. Good rail and air transport links with markets in Europe, North America and Asia Pacific made it an attractive proposition along with a burgeoning Western market for low-cost high quality aerospace standard precision machined parts and components Westerners, particularly from Northern Europe and North America are generally viewed as particularists (Trompenaars, 1993). They rely heavily on rules and legal agreements to structure and provide governance to cooperative ventures. Trompenaars, F.

RSA encryption :: Mathematics Math
RSA encryption All over the world there are millions of people use credit card and on-line shopping. Every individual gets different numbers for credit card and for transcription of on-line-shopping. Where did all this number come from? Are the numbers in order? No, those numbers are made by RSA algorithm. RSA encryption is the foundation of public key cryptography security products. For example, credit card companies use the RSA algorithm for customersââ¬â¢ individual online WebPages. The credit card companies publish a big number on WebPages, which is made by big prime numbers using the RSA algorithm. Since neither computers nor people can factor such big numbers, the RSA encryption system has secured many customersââ¬â¢ information. The RSA encryption is related to the cipher of Julius Caesar (1300s) that shifts three letters to encode messages. The cipher of Julius Caesar was used in war to send messages securely. Here is how Caesar encodes his message using the cipher. First Caesar assigned A through Z to 0 through 25. For instance A is zero. Second, add three to each numbers. Then, Caesar changed number into Alphabet again. The problem of the cipher of Julius Caesar is that it can be easily decoded by anyone because shifting three letters is not that hard to decode. However, the RSA system is much safer than the Caesar system because the RSA system uses huge numbers made by two big prime numbers using a special formula. RSA is named after three researchers( Ronald Rivest, Adi Shamir, and Leonard Adelman) from MIT. They searched for implementation to complete PKC system and found the RSA system among 40 candidates of formulas. PKC is the enabling technology for all Internet security and the increasing use of digital signatures, which are replacing traditional signatures in many contexts. However, RSA is better than PKC because RSA doesnââ¬â¢t need digital signature. As a result, the RSA algorithm turned out to be a perfect fit for the implementation of a practical public security system. In 1977, Martin Gardner first introduced the RSA system. After 5 years, company RSA used secure electronic security products. Nowadays many credit companies of all over the world use the RSA system or a similar system based on the RSA system. Why is the RSA system considered to be secure? As I mentioned before, neither computers nor people can factor really big numbers. Although the computer is suitable for calculating huge numbers, computers canââ¬â¢t factor numbers made by the RSA algorithm.

Egocentrism: The Epicenter of Fuzzy Ethics Essay
Egocentrism is a trait that not the highest of the morally esteemed in society will evade. Ideally this is what Aratani is ascertaining. Formatively, take the much ascribed moral class, the clergy. This purported moral class is always and will always front for their faith to have the highest attendance. They will promise miracles, traversing bounds of wealth through to healing; yet they ultimately do not deliver to the very word. One will refrain from terming this as cheating, given the moral and the spiritual authority from which the confession comes from (Deremer, P A.; Gruen, G E). Thinking outside this bracket, expecting more morality from the sheep when the shepherd has not towed the line seems relatively protracted; the epicenter of this discourse. Aratani simply appears to be arguing for what Maslowââ¬â¢s hierarchy of needs is meant to ascertain. In deed, from one level of satisfaction humanity will always yearn to move to the next. As Aratani asserts, when the player wins any base ball match, the worst the player will yearn for is to remain in that position; win and win and win! Or at best, improve on the record (Hanson, K O). Worse still, kill to remain at the very helm. This is shear presentation of utter egocentrism. The attitude of winning presents a competitive scenario for the world, which ultimately translates into innovation. However, cheating to meet this end is simply extraverted negative egocentrism. The reason for this trend appears relatively similar under varying circumstances. Whatever the orientation, the ethical miscreant simply endears to remain the very best, not to be outwitted by any other person (Deremer, P A. et al). One will argue that this is ideally competition. But then it is not moral to use the two words interchangeably or as synonyms. Presumably, the ideals of competition are more positive while those of egocentrism are negative and subverting. In effect blaming the entire yearning for more by any perpetrator of such traits would equally be senseless. Take the case of Drogba, after winning the trophy for the category of the best boot; all commercials use him for advertising their brands. Every brand pays him a fortune, his wealth increases at the rate of ticking seconds. Definitely signs that this trend of cash and fame inflows will be guarded at all possible costs (Aratani, L. ). In earnest it is not the will of the perpetrator; the world creates all the precedence for such occurrences. According to Maslow, the apex of humanity is self actualization. However, there seems to be no such ideal case as self actualization. If such cases existed, probably the cases of cheating and conspiracy to achieve this anterior end would just be reduced. I feel it is the search for supremacy, due the lack of the actualization stage, stable state, which precipitates the incessant lies and anterior activities. Ideally capitalism has a hand, s invisible yet so invincible in orientation in all these undertakings. Earnestly, if the wealth created in this due process would be shared within the community, then not the least individual will yearn to amaze as much wealth (Hanson, K O). Vividly, humanity would only look for as much as can sustain them without going beyond ethical boundaries to access more. It is utterly impossible or near to impossible perceiving any change in attitude that would see the overall yearning for more and more changed. If indeed religion was any practicable ideal, it would offer a worth course, but then it is equally bedeviled by the relentless yearning for more; believers, offerings, miracles and even wealth, earthly and heavenly alike. On the backdrop of this assertion, the best way towards ethical morality is socialism. Within the principles of socialism, and yet still given the egocentric nature of humanity, but as a curtailment, no individual will want to simply amaze much only to be used by the masses. People will only yearn for moderation in fame and wealth (Aratani, L. ). The need for actualization will be universalized and the need for craving for more will be curtailed. Ultimately, the course for reduced egocentrism is as course; whichever the approach, the solution towards this end is utterly individual reevaluation and rethinks. References Aratani, L.

NATURE OF SCIENCE Definition: Science can be defined as study ââ¬Å"mainly concerned with the phenomenon of physical universe any or all of natural sciences or biological sciences. Or Science as the ââ¬Å"the field of study which attempts to describe and understand the nature of the universe in whole or part. â⬠Science is the faculty to reason out the how and why of the things as they occur in the phenomenal world or t he objective worldâ⬠¦ Basically science is the study of laws of nature and man has developed science by observing. Infact this subject has completely transformed our power over nature and the world outlook. Development of the modern technology is directly the outcome of the development of modern science.Without the scientific revolution the industrial revolution would not have been possible. It has raised the human activity level by significant observations in the various fields of human existence. Whether itââ¬Ës the exploration of human health, industrial progress, agrarian developments and modern communication technologies, the benefits gained from this major subject are enormous. Infact it would not be wrong to say that we are living in the age of science and is a dominant factor in our day to day existence. 2. CONTRIBUTIONS OF MUSLIM SCIENTISTSMUHAMMAD BIN MUSA AL KHWARZIMI: Made lasting contributions in the fields of Mathematics, Astronomy, Music, Geography and History. He composed the oldest works on Arithmetic and on Algebra. The oldest Mathematic book composed by him is ââ¬Å"Kitab ul jama wat tafriqâ⬠He is the first person who used zero and wroteâ⬠Hisab ul jabr Wal Muqablaâ⬠which is conceived to be an outstanding work on the subject which included analytical solutions of linear and quadratic equations. In the field of Astronomy he compiled his own tables which formed the basis of later astronomical pursuits in both East and West.He also contributed in the field of geographical science by writing a noteworthy book KItab ul Surat al ard. In Arabic. His book ? kitab al Tarikâ⬠is also a memorable work regarding history. AL BERUNI: Born in Afghanistan Beruni made original important contributions to science. He is conceived to be the most prominent scientists of the Islamic world who wrote around 150 books on various significant subjects concerning human existence. These subjects include Mathematics, History, Archeology, Biol ogy, Geology, Che m is try, Religion etc.He discussed the behavior of earth, moon, and planets in his book ââ¬Å"Qanoon Almasudiâ⬠which is also considered as an outstanding astronomical encyclopedia. He also discovered seven different ways of finding the directions of north and south and discovered mathematical techniques to determine exactly the beginning of the seasons. Another notable discovery he made was that the speed of light is faster than sound . His wide range of scientific knowledge is also revealed through his booksâ⬠kitab al saidanaâ⬠and ââ¬Å"kitab al jawaharâ⬠dealing with medicine and the types of gems their gravity respectively.He was a prolific writer whose works showed his versatility as a scientist. AL RAZI: The famous philosopher and a notable surgeon of the Muslim world, Zakriya Al Razi was born in Ray near modern Theran Iran. His eagerness for knowledge lead him to the study of Alchemy and Chemistry, philosophy, logic, Mathematics and Physics. He was a pioneer in many areas of medicine and treatment of health sciences in general, and in particular he worked alot in the fields of paeditrics, obsterics and ophthalmology.Al razi was the first person to introduce the use of Alcohol for medical purposes and opium for the objective of giving anesthesia to his patients. In the field of ophthalmology too Al razi gave an account of the operation for the extraction of the cataract and also the first scientist to discover the effect of the intensity of light on the eye. The modern studies confirm his understanding on the subject thus making him a great physician of all the times. ABU ALI IBN E SINA: Endowed with great powers of absorbing and retaining knowledge this Muslim scholar also made valuable contributions to he field of science. He is considered to be the founders of Medicine and also added his great efforts to the fields of Mathematics, Astronomy, Medicinial Chemistry, Philosophy, Palae ontology and Music. His most famous book is ââ¬Å"Al Qannunâ⬠which brings out the features of human physiology and medicine. Sina is also considered as a father of the science of Geology on account of his invaluable book on mountains in which he discussed matters relating to earth's crust and gave scientific reasons for earthquakes.He is the author of 238 books which are fine instances of his thoughts regarding various subjects in diverse ways. JABIR BIN HAYAN: Introduced experimental research in chemical science which immensely added its rapid development and made him the Father of Chemistry. He devised methods for preparation of important chemicals like hydrochloric acid, nitric acid, and white lead. 3 Jabir's work also deal with the refinement of metals ,preparation of steel, dyeing of cloth and leather, use of magnese dioxide in glass making, distillation of vinegar to concentrate acetic acid.Jabir also explained scientifically two principle functions of chemistry, i. e. , calcination, and reduction and registered a marked improvement in the methods of evaporation, sublimation, distillation and crystallization He wrote more than 100 books which are one of the most outstanding contributions in the field of science especially the chemical science. ABDUL HASSAN IBN AL HAITHAM: One of the most outstanding Mathematicians, Physiologists, and Opticians of Islam. He contributed to the realms of medicine and philosophy. He wrote more than 200 scientific works on diverse subjects.Haitham examined the refraction of light rays through transparent objects including air and water. Infact he was the first scientist to elaborate two laws of reflection of light He made a number of monumental discoveries in the field of optics ,including one which locates retina as the seat of vision. His book on optics ââ¬Å"Kitab Al Manazirâ⬠vividly shows his grip on the subject. He constructed a pinhole camera and studied formation of images . Due to his noteworthy contributions he is regarded as one of the prolific Muslim scientists of all times.OMAR AL KHAYAM: He was an outstanding Mathematician and Astronomer. He was also known as a poet, philosopher and a physician. He travelled to the great centers of learning of the era i. e. Samrakund, Bukhara, and Ispahan. He classified many algebraic equations based on their complexity and recognized thirteen different forms of cubic equation. He also classified algebraic theories of parallel lines. On the invitation of Sultan Jalal-ud- Din, he introduced the Jilali calendar which has an error of one day in 3770 years.He also developed accurate methods for determination of gravity as a poet too, he is known for his Rubaiyat. He made great contributions in the development of mathematics and analytical geometry which benefitted Europe several years later. NASIR UD DIN TUSI: Al tusi was one of the greatest scientists, Mathematicians, Astronomers, Philosophers, Theologians and physicians of his time. He was a prolific writer and wrote many treatises on varied subjects like Algebra, Arithmetic, Trignometry, Geometery, Logic, Met aphy sics, medicine, ethics and Theology.He served as a minister of Halaku Khan and persuaded him to establish an observatory and library after the destruction of Baghdad. He worked at the observatory and prepared precise tables regarding the motion of the planets. These are also known as ââ¬Å"Tables of Khanâ⬠ZIA UD DIN IBN BAITAR: Was a famous botanist and pharmacopeias of middle ages. Because of his intensive travels, he was able to discover many plant species. He wrote many books regarding his field of specialty and is always considered as a prominent scientist among his Muslim counterparts 3.IMPACT OF SCIENCE ON SOCIETY Science is the organization of knowledge in such a way that it commands the hidden potential in nature. This hidden potential is surfaced out by the subject of science through the process of understanding. Science has proved to be of enormous beneficial nature . It h as made lasting impact on regarding each and every field of human existence. Whether it is concerned with our day to day lives or whether it is related with the various modern developments which have resulted in elevating the living standards of the individuals.The significant contributions which the study of this subject has made are enumerated below. SCIENCE AND HUMAN ATTITUDE: The various noteworthy scientific advances have helped the individuals in raising up of their self confidence . This subject has enabled the human beings to control and modify their needs and requriements. With greater understanding of the scientific phenomena human beings have now become more confident about the environmental issues as compared to the people in the past. Infact science has promoted and paved the way for the independent and logical thinking.SCIENCE AND HUMAN HEALTH: Before the development of modern medicinal factors, a large number of people used to lose their precious lives because of the unavailability of the sources and medicines for a proper health care. With the advancements of science now the human life expectancy rate has increased as the various modern developments in the field of health care has helped in warding off the dangerous diseasesâ⬠¦ The revolutions in surgery and medicine the infectious diseases like small pox, malaria, typhoid etc. have been eradicated. Thus science has improved the health standards of the people. SCIENCE AND TRAVEL: People used to travel on foot before the inventions of automobiles,aeroplanes and steam engines. They also used animal carts and camels for the purpose of moving from one place to another. However, the modern scientific inventions have proved to be of great significance as it has added speed to the area of travel. The quick means of transportation have decreased the distances and are a source of saving time. In fact it would not be wrong to regard that these inventions have added much peace to the lives of the mode rn men.SCIENCE AND COMMUNICATION: Science has also played a significant part in the development of the modern communication technology. Earlier people were living in isolation because of the slow means of communication. Now the well developed, efficient media have made it possible to communicate with each other more rapidly and quickly. The impact of mass media is enormous. The use of computers and televisions has made the world a global village where an event in one part of the world leaves an influence on the other.DEMERITS OF SCIENCE: Every invention of science has got its own merits and demerits. The most serious invention that science has contributed to is the development of the weapons of mass destruction like the atom and nuclear bombs. The recent wars have greatly showed that how much destruction can be brought about with the use of these lethal weapons. In fact these modern inventions of science have resulted in the elevation of the anxiety and unrest in the modern societie s. Another notable demerit which the study of this subject has lead to the rise in the environmental deterioration.Day by day the pollution factor is increasing which has proved to be very toxic and harmful for the human health. Not only the human health it is also proving fatal for the animals as well as the existing plants. The rapid developments of science and industrialization have also divided the world. The developed and the undeveloped. This division has lead to a widening gap between the status and the living standards of people. There is economic disparity which has also given rise to class distinction 4. UNIVERSEThe BIG BANG THEORY about the universe is the most widely acceptable theories with regard to the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions. All the galaxies were formed from this matter. Observations of these galaxi es show that they are still moving apart from each other . The universe is expanding Some scientists have suggested another theory as ââ¬Å"steady theory:â⬠to explain the process of the evolution of the universe.However the general notion on which all scientists agree is the theory of Big Bang. Steady theory is the theory about the universe and the observations by the astronomers have shown that the galaxies are moving away from each other and the universe seems to be expanding. The theory shows that the new matter is always being created to fill the space left by this expansion. The new matter moves apart and forms galaxies which continue to move apart. This means that the universe always look exactly the same. It has no beginning or end but in a steady state.However many observations have suggested that the universe has not always looked like the same. THE FUTURE OF UNIVERSE: At present the universe is expanding but the astronomers have questioned that whether or not this e xpansion will continue . Certain observations which have been made in this regard is that one possible ending of the universe will be the ââ¬Å"big crunch?. The galaxies and other matter may be moving apart but their motion is restrained by their mutual gravitational attraction. If there is a sufficient matter in the universe gravity will eventually win and egin pulling the galaxies together again causing the universe to experience a reverse of the big bang i. e. , the BIG CRUNCH. However there is a possibility that there is not enough matter in the universe for the big crunch to happen. This means that if it happens then the universe will continue to expand forever. 5. GALAXY Galaxy is a huge number of stars grouped together. The term galaxy can also be described as a collection of dust, gas and stars measuring thousands of parsecs across. Galzxy contains 10000million stars and looks like a disc with a fat centre and spiral arms.From the front it looks like a convex lensââ¬Ës C lasses of galaxy: Two broad classes of galaxy are there. 1. Elliptical 2. Spiral the spiral galaxies are further sub divided into normal which constitutes of majority of spirals and barred spirals. Barred spirals have their centre in the form of the bar. The elliptical galaxies range from E 0 to E 7 from an almost spherical shape to a flattened disc. 5 Milky Way: Our galaxy is a spiral galaxy about 30,000 parsecs across. There are more than 200 billion stars in the galaxy.Its disc appears as a faint white band that is responsible for dividing the white sky at the night into two. The name of our galaxy is Milky Way. The galaxy has three spiral arms called the Orion, Perseus, and Sagittarius arms and the whole system is rotating in space. The sun revolves around the nucleus of the galaxy once in 225 million years. This duration is also called the cosmic year. I -INTRODUCTION: Milky Way, the large, disk-shaped aggregation of stars, or galaxy, that includes the Sun and its solar system. In addition to the Sun, the Milky Way contains about 400 billion other stars.There are hundreds of billions of other galaxies in the universe, some of which are much larger and contain many more stars than the Milky Way. The Milky Way is visible at night, appearing as a faintly luminous band that stretches across the sky. The name Milky Way is derived from Greek mythology, in which the band of light was said to be milk from the breast of the goddess Hera. Its hazy appearance results from the combined light of stars too far away to be distinguished individually by the unaided eye. All of the individual stars that are distinct in the sky lie within the Milky Way Galaxy.From the middle northern latitudes, the Milky Way is best seen on clear, moonless, summer nights, when it appears as a luminous, irregular band circling the sky from the northeastern to the southeastern horizon. It extends through the constellations Peruses, Cassiopeia, and Cepheus. In the region of the Northern Cross it divides into two streams: the western stream, which is bright as it passes through the Northern Cross, fades near Ophiuchus, or the Serpent Bearer, because of dense dust clouds, and appears again in Scorpio; and the eastern stream, which grows brighter as it passes southward through Sputum and Sagittarius.The brightest part of the Milky Way extends from Sputum to Scorpio, through Sagittarius. The center of the galaxy lies in the direction of Sagittarius and is about 25,000 light-years from the Sun (a light-year is the distance light travels in a year, about 9. 46 trillion km or 5. 88 trillion mi). II -STRUCTURE: Galaxies have three common shapes: elliptical, spiral, and irregular. Elliptical galaxies have an ovoid or globular shape and generally contain older stars. Spiral galaxies are disk-shaped with arms that curve around their edges, making these galaxies look like whirlpools.Spiral galaxies contain both old and young stars as well as numerous clouds of dust and gas from whic h new stars are born. Irregular galaxies have no regular structure. Astronomers believe that their structures were distorted by collisions with other galaxies. Astronomers classify the Milky Way as a large spiral or possibly a barred spiral galaxy, with several spiral arms coiling around a central bulge about 10,000 light-years thick. Stars in the central bulge are close together, while those in the arms are farther apart. The arms also contain clouds of interstellar dust and gas.The disk is about 100,000 light-years in diameter and is surrounded by a larger cloud of hydrogen gas. Surrounding this cloud in turn is a spherical halo that contains many separate globular clusters of stars mainly lying above or below the disk. This halo may be more than twice as wide as the disk itself. In addition, studies of galactic movements suggest that the Milky Way system contains far more matter than is accounted for by the visible disk and attendant clustersââ¬âup to 2,000 billion times more mass than the Sun contains.Astronomers have therefore speculated that the known Milky Way system is in turn surrounded by a much larger ring or halo of undetected matter known as dark matter. III -TYPES OF STARS: The Milky Way contains both the so-called type I stars, brilliant, blue stars; and type II stars, giant red stars. Blue stars tend to be younger because they burn furiously and use up all of their fuel within a few tens of millions of years. Red stars are usually older, and use their fuel at a slower rate that they can sustain for tens of billions of years.The central Milky Way and the halo are largely composed of the type II population. Most of this region is obscured behind dust clouds, which prevent visual observation. Astronomers have been able to detect light from this region at other wavelengths in the electromagnetic spectrum, however, using radio and infrared telescopes and satellites that detect X rays (see Radio Astronomy; Infrared Astronomy; X-Ray Astronomy). Su ch studies indicate compact objects near the galactic center, probably a massive black hole. A black hole is an object so dense that nothing, not even light, can escape its intense gravity.The center of the galaxy is home to clouds of antimatter particles, which reveal themselves by emitting gamma rays when they meet particles of matter and annihilate. Astronomers believe the antimatter particles provide more evidence for a massive black hole at the Milky Wayââ¬Ës center. Observations of stars racing around the center also suggest the presence of a black hole. The stars orbit at speeds up to 1. 8 million km/h (1. 1 million mph)ââ¬â17 times the speed at which Earth circles the Sunââ¬âeven though they are hundreds of times farther from the center than Earth is from the Sun.The greater an objectââ¬Ës mass, the faster an object orbiting it at a given distance will move. Whatever lies at the center of the galaxy must have a tremendous amount of mass packed into a relatively small area in order to cause these stars to orbit so quickly at such a distance. The most likely candidate is a black hole. Surrounding the central region is a fairly flat disk comprising stars of both type II and type I; the brightest members of the latter category are luminous, blue supergiant.Imbedded in the disk, and emerging from opposite sides of the central region, are the spiral arms, which contain a majority of the type I population together with much interstellar dust and gas. One arm passes in the vicinity of the Sun and includes the great nebula in Orion. See Nebula. 6 IV -ROTATION: The Milky Way rotates around an axis joining the galactic poles. Viewed from the north galactic pole, the rotation of the Milky Way is clockwise, and the spiral arms trail in the same direction. The period of rotation decreases with the distance from the center of the galactic system.In the neighborhood of the solar system the period of rotation is more than 200 million years. The speed of t he solar system due to the galactic rotation is about 220 km/sec (about 140 mi/sec). 6. SOLAR SYSTEM The solar system includes nine planets and sun being at the centre. All the planets revolve around the sun . The solar system also includes the asteroids, meteors and numerous comets. All of these travel around the sun in a particular orbit . The planets which are the significant part of the solar system namely,Mercury,venus,earth,mars,Jupiter,Saturn

Copyright Notice and the Use of the Copyright Symbol
Copyright Notice and the Use of the Copyright Symbol A copyright notice or copyright symbol is an identifier placed on copies of the work to inform the world of copyright ownership. While the use of a copyright notice was once required as a condition of copyright protection, it is now optional. Use of the copyright notice is the responsibility of the copyright owner and does not require advance permission from, or registration with the Copyright Office. Because prior law did contain such a requirement, however, the use of a copyright notice or copyright symbol is still relevant to the copyright status of older works. The copyright notice was required under the 1976 Copyright Act. This requirement was eliminated when the United States adhered to the Berne Convention, effective March 1, 1989. Although works published without copyright notice before that date could have entered the public domain in the United States, the Uruguay Round Agreements Act (URAA) restores copyright in certain foreign works originally published without copyright notice. How Is a Copyright Symbol Useful Use of the copyright notice may be important because it informs the public that the work is protected by copyright, identifies the copyright owner, and shows the year of first publication. Furthermore, in the event that a work is infringed, if a proper notice of copyright appears on the published copy or copies to which a defendant in a copyright infringement suit had access, then no weight shall be given to such a defendants defense based on innocent infringement. Innocent infringement occurs when the infringer did not realize that the work was protected. The use of the copyright notice is the responsibility of the copyright owner and does not require advance permission from, or registration with, the Copyright Office. Correct Form for the Copyright Symbol The notice for visually perceptible copies should contain all the following three elements: The copyright symbol à © (the letter C in a circle), or the word Copyright, or the abbreviation Copr.The year of first publication of the work. In the case of compilations or derivative works incorporating previously published material, the year date of first publication of the compilation or derivative work is sufficient. The year date may be omitted where a pictorial, graphic, or sculptural work, with accompanying textual matter, if any, is reproduced in or on greeting cards, postcards, stationery, jewelry, dolls, toys, or any useful article.The name of the owner of copyright in the work, or an abbreviation by which the name can be recognized, or a generally known alternative designation of the owner. Example: copyright à © 2002 John Doe The à © or C in a circle notice or symbol is used only on visually perceptible copies. Phonorecords Certain kinds of works, for example, musical, dramatic, and literary works may be fixed not in copies but by means of sound in an audio recording. Since audio recordings such as audio tapes and phonograph disks are phonorecords and not copies, the C in a circle notice is not used to indicate protection of the underlying musical, dramatic, or literary work that is recorded. Copyright Symbol for Phonorecords of Sound Recordings Sound recordings are defined in the law as works that result from the fixation of a series of musical, spoken, or other sounds, but not including the sounds accompanying a motion picture or other audiovisual work. Common examples include recordings of music, drama, or lectures. A sound recording is not the same as a phonorecord. A phonorecord is a physical object in which works of authorship are embodied. The word phonorecord includes cassette tapes, CDs, records, as well as other formats. The notice for phonorecords embodying a sound recording should contain all the following three elements: The copyright symbol (the letter P in a circle)The year of first publication of the sound recordingThe name of the owner of copyright in the sound recording, or an abbreviation by which the name can be recognized, or a generally known alternative designation of the owner. If the producer of the sound recording is named on the phonorecord label or container and if no other name appears in conjunction with the notice, the producers name shall be considered a part of the notice. Position of Notice The copyright notice should be affixed to copies or phonorecords in such a way as to give reasonable notice of the claim of copyright. The three elements of the notice should ordinarily appear together on the copies or phonorecords or on the phonorecord label or container. Since questions may arise from the use of variant forms of the notice, you may wish to seek legal advice before using any other form of the notice. The 1976 Copyright Act overturned the strict consequences of failure to include copyright notice under prior law. It contained provisions that set out specific corrective steps to cure omissions or certain errors in the copyright notice. Under these provisions, an applicant had 5 years after publication to cure omission of notice or certain errors. Although these provisions are technically still in the law, their impact has been limited by the amendment making notice optional for all works published on and after March 1, 1989. Publications Incorporating United States Government Works Works by the U. S. Government are not eligible for U.S. copyright protection. For works published on and after March 1, 1989, the previous notice requirement for works consisting primarily of one or more U. S. Government works has been eliminated. However, use of a notice on such a work will defeat a claim of innocent infringement as previously described provided the copyright notice also includes a statement that identifies either those portions of the work in which copyright is claimed or those portions that constitute U. S. Government material. Example: copyright à © 2000 Jane Brown.Copyright claimed in Chapters 7-10, exclusive of U. S. Government maps Copies of works published before March 1, 1989, that consist primarily of one or more works of the U. S. Government should have a notice and the identifying statement.

Kosmoceratops - Facts and Figures
Kosmoceratops - Facts and Figures Name: Kosmoceratops (Greek for ornate horned face); pronounced KOZZ-moe-SEH-rah-tops Habitat: Plains and woodlands of North America Historical Period: Late Cretaceous (75-65 million years ago) Size and Weight: About 15 feet long and 1-2 tons Diet: Plants Distinguishing Characteristics: Quadrupedal posture; ornate skull with numerous horns and downward-curving frill About Kosmoceratops For years, Styracosaurus held the title as the worlds most ornately decorated ceratopsian dinosauruntil the recent discovery of Kosmoceratops (Greek for ornate horned face) in southern Utah. Kosmoceratops sported so many evolutionary bells and whistles on its massive skull that its a wonder it didnt topple over when it walked: this elephant-sized herbivores head was decorated with no less than 15 horns and horn-like structures of various sizes, including a pair of large horns above its eyes vaguely resembling those of a bull, as well as a downward-curving, bizarrely segmented frill completely unlike anything seen in any previous ceratopsian. As is the case with another recently discovered horned frilled dinosaur, Utahceratops, the strange appearance of Kosmoceratops can at least partially be explained by its unique habitat. This dinosaur lived on a large island in western North America, called Laramidia, that was demarcated and bordered by the shallow Western Interior Sea, which covered much of the continents interior during the late Cretaceous period. Relatively isolated from the mainstream of dinosaur evolution, Kosmoceratops, like the other fauna of Laramidia, was free to progress in its bizarre direction. The question remains, though: why did Kosmoceratops evolve such a unique combination of frill and horns? Usually, the main driver of such an evolutionary process is sexual selectionover the course of millions of years, female Kosmoceratops came to favor multiple horns and funky frills during mating season, creating an arms race among males to outdo one another. But these features may also have evolved as a way to differentiate Kosmoceratops from other ceratopsian species (it wouldnt do for a juvenile Kosmoceratops to accidentally join a herd of Chasmosaurus), or even for purposes of communication (say, a Kosmoceratos alpha turning its frill pink to signal danger).

2 drafts to peer review Essay Example | Topics and Well Written Essays - 250 words
2 drafts to peer review - Essay Example Of course the story will directly not tell what that meant which makes it more interesting because it leaves us to fill the gap by our interpretation of the story. It would have been nice if the interpretation was included. In essence, James Baldwinââ¬â¢s Sonnyââ¬â¢s Blues s about a personââ¬â¢s struggle, discovery and liberation of which every human being undergo to a relative extent. Probably the reason why there was an attempt to keep the narrator anonymous is to maintain the universality of the story. Albeit it may spoke of the struggle of the African-American against segregation and prejudices, the same struggle is also experienced by other people although the challenge may take in different form. The paper ââ¬Å"gotâ⬠the gist of the story and just needs some polishing. It was also nice that some quotations were included to emphasize a point such quoting ââ¬Å"low ceilings of their actual possibilitiesâ⬠when complacency was talked about. It progresses to select some sceneââ¬â¢s in the work to highlight aspects of the story making it more detailed without being too

The Proofs of the Existence of God Essay Example | Topics and Well Written Essays - 1500 words - 119
The Proofs of the Existence of God - Essay Example Humanity has searched for the discovery of the nature of God for a long time since the conscious living. It is important to realize, whether people have any reason to believe in God's existence ââ¬â or His absence. Faith widely does not incorporate reasoning. It looks like that these two areas of human perception lie in the parallel layers if reality and, thusly, do not cross. How does the concept of Godââ¬â¢s foreknowledge correspond the concept of human freedom? There are also debated represented widely on the topics around the creationism and evolution. There is the question, what is the real role of the God in the creation of the universe and was He actually the one, who forced all this to start from the beginning of times? à One of the brilliant approaches was proposed by one of the greatest figures in the fields of philosophy, mathematics, and physics ââ¬â Blaise Pascal. He is a genius of French origin, who invented the first mechanical adding machine. He also was one of the developers (together with Fermat), of modern probability theory. He was a genius indeed, as he invented his basic theorem of projective geometry at the age of 16 only. All the before-mentioned aimed to ensure the credibility and authority of the weight of his argument from probability for believing in Godââ¬â¢s existence (Hacking). His approach is absolutely practical. It simply claims that the expected utility of belief in the existence of God far outreaches the expected utility of the absence of belief in God. Defining what he meant by that, it is important to know that he was a brilliant mathematician and his approach is absolutely logical and well-structured.
