Asexual vs. Sexual Reproduction in Evolution

Asexual vs. Sexual Reproduction in Evolution The mechanism for evolution is natural selection. Natural selection is the process that decides which adaptations for a given environment are favorable and which are not as desirable. If a trait is the favored adaptation, then individuals that have the genes that code for that characteristic will live long enough to reproduce and pass down those genes to the next generation. In order for natural selection to work on a population, there must be diversity. To get diversity in the individuals, genetics need to be different and different phenotypes must be expressed. This is all dependent upon the type of reproduction the species undergoes. Asexual Reproduction Asexual reproduction is the creation of offspring from one parent. There is no mating or mixing of genetics in asexual reproduction. Asexual reproduction results in a clone of the parent, meaning the offspring have identical DNA as the parent. There is usually no variation from generation to generation in a species population that relies on asexual reproduction. One way for an asexually reproducing species to get some diversity is through mutations at the DNA level. If there is a mistake in mitosis or the copying of the DNA, then that mistake will be passed down to the offspring, thereby possibly changing its traits. Some mutations do not change the phenotype, however, so not all mutations in asexual reproduction result in variations in the offspring.​ Sexual Reproduction Sexual reproduction happens when a female gamete (or sex cell) unites with a male gamete. The offspring is a genetic combination of the mother and the father. Half of the offsprings chromosomes come from its mother and the other half come from its father. This ensures the offspring are genetically different from their parents and even their siblings. Mutations can also happen in sexually reproducing species to further add to the diversity of the offspring. The process of meiosis, which creates the gametes used for sexual reproduction, has built-in ways to increase diversity as well. This includes crossing over, which ensures the resulting gametes are all different genetically. Independent assortment of the chromosomes during meiosis and random fertilization also add to the mixing up of genetics and possibility of more adaptations in offspring. Reproduction and Evolution Generally, it is believed that sexual reproduction is more conducive to driving evolution than asexual reproduction. With much more genetic diversity available for natural selection to work on, evolution can happen over time. When evolution does occur in asexually reproducing populations, it typically happens very quickly after a sudden mutation. There usually is not a long time of accumulating adaptations like there is in sexually reproducing populations. An example of this relatively quick evolution can be seen in drug resistance in bacteria.

What features of Cloudstreet contribute to its textual integrity Essay Example

What features of Cloudstreet contribute to its textual integrity Essay Example What features of Cloudstreet contribute to its textual integrity Essay What features of Cloudstreet contribute to its textual integrity Essay Essay Topic: Literature True Grit Cloudstreet, written by Tim Winton, has all the requirements and qualities of a text with textual integrity. Textual integrity consists of structure, form and language which create a meaning. Cloudstreet is a family saga which employs a generally linear and sometimes circular structure. It meets the criteria of a saga in two ways. Firstly, it takes place over 4 generations, and even though the oldest generation is only embodied through memories and dreams it does help the narrative achieve resolution by bringing the reader closer to the Cloudstreet characters. Secondly the novel takes place over 25 years and speaks of events that actually took place in the time the novel was set; WWII, Nedlands Murders. Through Wintons use of chapters and sub headings the readers do not notice time passing but the important details instead. The structure is mostly linear but there are times which incorporate flashbacks or are in dream-mode. These modes are important for the reader to fully understand each character and their way of thinking. It is important that past events be recognised as they are an essential part of the story. Such is when Quick is out shooting roos and Fish comes to him in a Harvey oranges box with tomato stakes for oars. Across the still waters of the sunburnt crop wherein lies Quick Lamb breathing without help He took my bloody dog (page 201). This shows that the water essence is always with each character. The fact that the house was originally inhabited by Indigenous girls who subsequently were abused, helps the reader to understand why Spiritual Fish hears the house breathing and crying and how he talks to dark ghosts. All of Wintons characters are restless and seek meaning in a world where an explanation isnt easy to find. Their dialogue defines their class of people; the characters use idioms like carn in place of come on and the recognisable events such as the Nedlands Murders give the text, textual integrity. Winton creates viable, believable and realistic characters by using dialogue, specific language techniques and point of view. Winton uses multiple narrators; Omniscient, stream of consciousness (Fish, Oriel) and interior monologue (Rose, Lester). Its Fishs spiritual narration that lets the reader in on otherwise inaccessible information which is unattainable from the other often inarticulate characters. Inarticulateness, Australian vernacular and alcoholism, were Australian traits evident in many novels and plays written about Post-War Australia such as The Touch of Silk by Betty Roland and Summer of the Seventeenth Doll by Ray Lawler. This shows Cloudstreet was a true depiction of Post-War, poorly educated, working class, Aussie battlers and shows its viability and textual integrity. Winton enhances the textual integrity of his novel by giving the characters distinctly Australian qualities and they fit the Western Australian war time period they are placed in. The characters are all laconic and use colloquialisms such as that on page 399; Lon Lamb has taken a sickie off work Dolly is sarcastic and cynical. When Sam lost his fingers all Dolly could say was; His bloody working hand. A man could hardly pick his nose with a thumb and half a pointer. They were done for; stuffed, cactus. Thank you, Lady Luck, you rotten slut. Wintons Characters carefully chosen names evoke an image into the readers mind of what the character should be. These ideas are immediately vanquished. Take Rose, a rose is a delicate flower with fine features and a beautiful aura but Rose Pickles is a hateful woman, though beautiful she is spiteful and hard. Dolly is just like her daughter, in that she is hardened. Dolly is also an alcoholic and sex-crazed woman who spends most of her time at the pub drinking and vying for male attention. These two strong women contradict their pleasant names and also hate each other. Fish, like the creatures, observe the immeasurable depths of experience and all he can think about is the river. The surnames of the two Cloudstreet families are Pickles and Lamb. A club sandwich with so many characteristics all piled under the same roof of Cloudstreet. Cloudstreet is written using a paradox. Although Fish is intellectually disabled he is the main narrator in the book. Once favourite, who after the accident became stuck somewhere like hes half in and half out. Not all of Fish had come back and in his half state of life hes become a spiritually liberated and insightful being. His refusal to acknowledge his mothers presence is ironic because it if wasnt for her stubborn and sheer will power Fish would never have come back at all. Winton uses symbolism and themes (the black man, house and river) as a central part of Cloudstreet, especially the river. All the major life changing events take place at the river; Fish drowns then gets brought back to life, Rose and Quick acquaint themselves, Quick and his mother open up to each other and then finally Fish dies there. The setting has been given life by Winton as he explores Australia. He uses personification to show a connectedness between humanity and the land. He also uses personification when he writes about the house that moans and groans with the lost souls of the indigenous Australians. The house along with the river is the place where everything starts and finishes (circular structure). The house brings the two families together and its the place where the two families really are brought together when Quick and Rose make love to each other and Dolly and Lester have sex. Fish also understands the room that nobody else can bear to enter. He hears the house crying at night and he feels its pain. Winton also in a way personifies the pig. There is no real reason for the pig except comical relief but Fish understands it, for its his spiritual side that allows this. The pig speaks in its own tongue much like the Glossolalia of Pentecost in the New Testament. Another biblical reference. Cloudstreet has many biblical over-tones such as: The Lambs are believers in the bible, Beryl, and even a sub heading, Disciples on page 247 relates to the bible. Another theme Winton explores is women and men in this time. Australia was a male centred society and the values of women were restricted to their sexuality and ability to be nurturers. Dolly and Oriel have opposing views about the men in their lives. Dolly desires the mens attention where Oriel battles through life despite men. The women are the rock in the unstable lives of their families, they shape the children, and men and make everything function while the men create predicaments and problems. Oriel and Dolly; however different their views, are the symbols of the plight of women in a manly world. Beyond Cloudstreet lies a world that is male orientated, where within the walls of their home, everything is shaped by women. The men live in their past and memories and are largely unaware of the real world around them. E. G: Lester relieves his glories at the ANZAC club. Although when an emergency arises, the men find the answers because they are spur-of-moment characters. Such is when Lester lends Sam money for his debt. The men may be good with physical encounters but they make themselves scarce for emotion catastrophes. Cloudstreet has textual integrity. It does not chop and change its ideals throughout the novel and its main themes stay the same. Everything Cloudstreet entails is true and viable. There is no doubt that Cloudstreet has textual integrity.

Self-efficacy in reading and language arts Research Paper

Self-efficacy in reading and language arts - Research Paper Example First an introduction has been given as to what contribution has technology made in education and especially the teaching of language. Then, teachers’ competencies and barriers to the integration of technology have been discussed. After that, various technological strategies are discussed which the teachers can make use of in classrooms to motivate students and facilitate their language teaching process. Introduction Since the advent of sophisticated technological means, educators have been trying to modify the instructional process with the help of technology. Early 1960’s brought with it new curricula and instructional models of instruction, but the drawback with these instructional schemes was their poor management. Last decades have seen much advancement in this regard. An ideal classroom environment is so dynamic in which each student is motivated to present his own understanding, and where he is comfortable with his own set of instructional materials. Thus, the te acher needs to organize instructional and motivational schemes in such a way that all students with their unique calibers are equally attended to. Today, the educational institutes are aware of the necessity of incorporating information and communication technology in teaching language to enhance student motivation and learning. Literature Review Ismail, Ghaleb and Almekhlafi (2010, p.37) studied teacher perception regarding teaching Arabic and English languages in schools in UAE. They found that teachers’ support and willingness to incorporate technology in their teaching languages is very important to motivate students to learn effectively. The researchers discussed the benefits of the usage of IT both for the teachers and the students, and found from their qualitative and quantitative research that teacher perception should be considered seriously for better implementation of technological tools in classrooms. Woodrow (as cited. in Ismail, Ghaleb & Almakhlefi, 2010, p.37) asserts, â€Å"teachers are seen to be active agents in the process of changes and implementation of new ideas as their beliefs and attitudes may support or impede the success of any educational reform such as the utilization of an innovative technology program.† So, it can be stated that technological advances have greatly facilitated student motivation to learn through enhanced teaching processes. The teachers today can use many technological tools to equip themselves while teaching languages to their students. Mansor (2007) asserts that the technological advances have greatly benefitted the learning of English language for students. However, it still has to go a long way as, according to what Ismail, Ghaleb and Almakhlefi (2010) found in their research, teachers were still reluctant to use technological facilities in teaching languages like Arabic. Yaratan and Kural (2010, p.161) studied the implementation of instructional technology in teaching English language in North C yprus schools. They conducted the survey among 80 teachers, and concluded that although teachers were willing to use technology in teaching language, still the rate was low because there were not enough technological means to employ nor there was enough time. However, they found that the teachers who were

Technology - Essay Example In case the private body functions in a public capacity and it is owned, controlled and funded by the state, then it should be considered as a public body. However, a private corporation is subject to the FOIA request when they utilize public funding under the conditions that the entity performs the functions of the government, government is involved in regulation, and when the entity is formed by the government. Also, the federal standards should not be used in determining the public funding by the private corporation, and the criteria by FOIL should come into play in matters related to the functioning of the private agency (Halstuk & Bill, 2006). The traditional privatization approaches of the public services can be approached in a perspective which considers government as hierarchical and ineffective, and that it involves both benefits and difficulties while importing efficiency and flexibility in the corporate world to provide for the public services. Bring the for-profit corporation to the delivery of the traditional government services is contentious. Some of the questions that may arise are whether the state can be sued along the private corporation and whether the government actors are entitled to immunities. The two partnerships can be of considerable legal work and to untangle. Youth detention centers and private prisons are under control of the government entities, such that more money is realized by having more inmates (Silverman, 2007). On the other hand, the economic difficulties facing the private sector in using the public funds for the non-traditional services is caused by the reassessment of the priorities for county and municipal governments. Government is faced with problems when trying to balance services to the community and the declining tax revenues (Halstuk & Bill, 2006). Fraud, waste, abuse and corruption are problems in government programs. FWAC in small businesses led to Nancy Pelosi, who was the house speaker instructed

Social and economic disadvantage for some ethnic groups in Britain Essay - 1

Social and economic disadvantage for some ethnic groups in Britain - Essay Example In determining values of different capitals and power development directs towards providing benefits to a section of people of the society while making it worse for the other people in that society(Social Class, 2012). In this respect, ethnicity is one of the major parameters associated with social capitals and in Britain it has been empirically found that ethnic minorities have been subjected to various disadvantages. The social scientists have propounded intersection theory which states that the intersection of race, class and gender fetches multiple disadvantages to the people in the societal and economic forefront (Macionis, 2006, p.350). Ethnicity forms one of the most important dimensions of identities of minority ethnic group but at the same time intersect with other social divisions like that of â€Å"age, ability, class, gender and sexuality† (Craig et al, 2012, p.211). In this paper, the main focus is to carry on a critical assessment of the ways in which ethnicity i ntersects other social divisions in the creation of social and economic disadvantage for some ethnic groups in Britain. In course of discussion, focus will be entailed on theoretical foundation. Although critical assessment will be made with respect to living standards, social security but education which is one of the major indicators in the determination of social and economic development will be also given special emphasis. The social scientists in analyzing the social classes often consider a stark difference in the ethnicity forefront.

Discoveries And Inventions In Fundamental Sciences History Essay

Discoveries And Inventions In Fundamental Sciences History Essay There is a general concept that the sciences are exclusively the products of Western minds. Review of any standard book or encyclopedias regarding the history of science makes evident that the only contributors are Europeans and/or Americans. The most oft-mentioned names are Kepler, Galileo, Copernicus, Bacon, Da Vinci, Franklin, Newton, Benjamin etc. Thus it is made unavoidable to conclude the major contributions to the development of the modern sciences by other cultures are minimal. The advancements made by ancient Chinese, Indian or particularly, Muslim scholars are hardly mentioned in most standard books and literature. Although Western civilization has made many invaluable contributions to the development of the sciences however, so have numerous other cultures. Unfortunately, Westerners have long been credited with discoveries that were made by muslims scientists many centuries before. Thus, many of the basic sciences were invented by non-Europeans. For instance, George Sarton states that modern Western medicine did not originate from Europe and that it actually arose from the (Islamic) orient. inShare91 515 points on reddit Major Inventions of Muslim Scientists: A number of inventions and discoveries were made by the Muslim scientists throughout the history. Muslim geographers and navigators learned the use of magnetic needle, from the Chinese, and were the first to use magnetic needles in navigation. Muslims invented the compass and its use in navigation, which was later on passed to the West. European navigators relied on Muslim pilots and their instruments while exploring the unknown territories. Gustav Le Bon claims that the magnetic needle and compass were the inventions of Muslims. The Chinese, probably learned of it from Muslim traders. It is noteworthy that after the interaction with the Muslims during the 8th century the Chinese improved their navigational expertise. Ibn Firnas a Muslim scientist of Islamic Spain invented, constructed and tested a flying machine in the 800s A.D. Roger Bacon learned of flying machines from Arabic references to Ibn Firnas machine. According to Will Durant, Ibn Firnas of Islamic Spain, invented a watch-like device in 9th century, which kept accurate time. The Muslims also constructed a variety of highly accurate astronomical clocks for use in their observatories. As early as the 9th century A.D Muslim mathematicians, the inventors of algebra, introduced the concept of using letters for unknown variables in equations. They solved a variety of complex equations through this system, including quadratic and cubic equations. They used symbols to develop and perfect the binomial theorem. Thabit bin Qurrah was among the first Mathematicians of the Islamic Empire who accomplished this precisely this as early as the 9th century A.D, and he was followed by Abul Wafa, whose 10th century book utilized algebra to advance geometry into an exact and simplified science. In the 9th century Muslim astronomers made numerous improvements upon Ptolemys findings. They were the first astronomers to dispute his archaic ideas. They produced hundreds of highly accurate astronomical tables and star charts. Many of their calculations are so precise that they are regarded as contemporary. Copies of works on astronomy the Alphonsine Tables was transmitted to Europe via Islamic Spain, i.e. the Toledo Tables. In their critic of the Greeks, Muslims synthesized proof that the sun is the center of the solar system and that the orbits of other planets and the earth might be elliptical. During the 9th century the Muslim physician originated the science of pharmacology and was developed into a highly refined and exact science. Muslim chemists, pharmacists and physicians produced thousands of drugs and/or crude herbal extracts one thousand years prior to the supposed birth of pharmacology. During the 9th century, eyeglasses were invented by Ibn Firnas of Islamic Spain and they were manufactured and sold throughout Spain for over two centuries. Any mention of eyeglasses by Roger Bacon was simply a regurgitation of the work of al-Haytham (d. 1039), whose research Bacon frequently referred to. During the 8th through 15th centuries, Muslim geographers produced untold volumes of books on the geography of Africa, Asia, India, China and the Indies. These writings included the worlds first geographical encyclopedias, almanacs and road maps. The 14th century masterpieces of Ibn Battutah provide a detailed view of the geography of the ancient world. The science of ethnography was invented by the Muslim scholars of the 9th through 14th centuries. A number of Muslim geographers classified the races, writing detailed explanations of their physical appearances and unique cultural habits. Blumenbachs works were insignificant in comparison. Muslim physicians used a variety of specific substances to destroy microbes. They applied sulfur topically specifically to kill the scabies mite. Ar-Razi (10th century) used mercurial compounds as topical antiseptics. During the 9th and 10th centuries, the Venetians learned of the art of fine glass production from Syrian artisans. Glass mirrors were in use in Islamic Spain as early as the 11th century. Ibn Yunus al-Masri discovered the pendulum in the 10th century, and was the first to study and document its oscillatory motion. Its value for use in clocks was introduced by Muslim physicists during the 15th century. Muslim mathematicians as early as the 10th century solved numerous equations of even higher degrees with ease. Binomial theorem was utilized and perfected for its use in the systematic solution of algebraic problems by hundreds of the Muslim mathematicians. In the 10th century numerous Muslim chemists produced medicinal-grade alcohol through the process of distillation and manufactured the first distillation devices on a large scale for use in chemistry. They used alcohol as a solvent and antiseptic. The prophet Muhammad wisely warned against entering or leaving a region suffering from plague thus introducing the concept of quarantine for the very first time in the 7th century A.D. later in the 10th century, Muslim physicians innovated the use of isolation wards for individuals suffering with communicable diseases. As early as the 10th century, Muslim physicians and surgeons of 10th century used to apply purified alcohol to wounds as an antiseptic agent. In Islamic Spain surgeons utilized special methods for maintaining antisepsis prior to and during surgery. The origin of specific protocols for maintaining hygiene during the post-operative period raised the success rate so high that dignitaries throughout Europe came to Cordova, Spain, to be treated at what was comparably the Mayo Clinic of the Middle Ages. Islams ar-Razi wrote an in-depth treatise on the venous system, accurately describing the function of the veins and their valves in the 10th century. Timeline of Muslim Scientists from 700 900 AD: 8th century: 700s [petroleum; civil engineering] In Baghdad the streets were constructed and paved with tar, coming from the petroleum that oozed in natural oil fields in the region.   700s 800s [cosmetics] In Spain a beauty institute was started by Ziryab (Blackbird). 740 828 Al-Amai, Zoology, Botany, Animal husbandry.   770 840 [mathematics] The Calculus of resolution and juxtaposition (hisab al-jabr wal-muqabala), more briefly referred to as al-jabr, or algebra, was developed by Kharazmi, Algebra was a unifying theory which allowed rational numbers, irrational numbers, geometrical magnitudes, etc., to all be treated as algebraic objects. It gave mathematics a whole new development path so much broader in concept to that which had existed before, and provided a vehicle for future development of the subject. Another important aspect of the introduction of algebraic ideas was that it allowed mathematics to be applied to itself in a way which had not happened before.   Al-Khwarizmis successors undertook a systematic application of arithmetic to algebra, algebra to arithmetic, both to trigonometry, algebra to the Euclidean theory of numbers, algebra to geometry, and geometry to algebra. This was how the creation of polynomial algebra, combinatorial analysis, numerical analysis, the numerical solution of equations, the new elementary theory of numbers, and the geometric construction of equations arose.   Late 700s 800 [musical science] Mansour Zalzal of Kufa was a musician (luth) and composer of the Abbasid era. Contributed musical scales that were later named after him (the Mansouri scale) and introduced positions (intervals) within scales such as the wasati-zalzal that was equidistant from the alwasati alqadima and wasati al-fors who made improvements on the design of the luth instrument and designed the Luth. In 715 800 [chemistry] The Muslim chemist, Geber (Jabir ibn Hayyan), is considered the father of chemistry, for introducing the experimental scientific method for chemistry, such as alembic, still, retort, pure distillation, liquefaction, crystallisation, purification, oxidisation, evaporation, and filtration. He was the first chemist known to produce sulfuric acid, as well as many other laboratory instruments and chemical substances. His works include The elaboration of the Grand Elixir, The chest of wisdom in which he writes on nitric acid, Kitab al-Istitmam (translated to Latin later as Summa Perfectionis), and many others.   715 800 [alchemy] Geber, introduced the first theories on the transmutation of metals, the philosophers stone, and the artificial creation of life in the laboratory.   715 800 [glass] Geber added colour to glass by introducing small quantities of metallic oxides to the glass, such as manganese dioxide (magnesia). This was a new advancement in the glass industry unknown in antiquity.   9th century: 800 868 [biology, zoology, linguistics, language,] Amr ibn Bahr al-Jahiz wrote a number of works on zoology, lexicography, rhetoric, and Arabic grammar. In his most famous book the Book of Animals, he was the first to discuss food chains, and environmental determinism by arguing that the environment can determine the physical characteristics of the inhabitants in a certain community he also stated that the origins of different colors of human skin is the result of the environment. The struggle for existence and the theory of evolution by natural selection was first discussed by him. 800 873 Ibn Ishaq Al-Kindi (Latinized, Alkindus.) was an expert in Optics, Metallurgy, Cryptography, Medicine, Mathematics, Physics and Philosophy. He worked at the House of Wisdom which was set up in 810. He introduces quantification into medicine in his book De Gradibus.   In 810 the works of Greek and Indian scientists on astronomy and mathematics were translated into Arabic in Bayt al-Hikma (House of Wisdom) which was set up in Baghdad. 820 [mathematics] Mahani (full name Abu Abdollah Muhammad ibn Isa Mahani in Arabic Al-Mahani). Conceived the idea of reducing geometrical problems such as duplicating the cube to algebraic problems.   836 901 [anatomy; astronomy; mathematics; mechanics] Born Thabit Ibn Qurra (Latinized, Thebit.) made considerable contributions in mathematics particularly in number theory and geometry while studying at Baghdads House of Wisdom under the Banu Musa brothers. He discovered the theorem by which pairs of amicable numbers can be found; i.e., two numbers such that each is the sum of the proper divisors of the other. Later, al-Baghdadi (b. 980) and al-Haytham (born 965) developed variants of the theorem.   838 870 Tabari (full name: Ali ibn Sahl Rabban Al-Tabari) made many contributions in Calligraphy, Mathematics, Literature, and Medicine.   In mid 800s [chemistry] Al-Kindi gave 107 recipes for making perfumes and also wrote on the distillation of wine as that of rose water, in his book Kitab Kimia al-`otoor wa al-tas`eedat (book of the chemistry of perfumes and distillations).   850 930 [mathematics] Abu Kamil of Egypt (full name, Abu Kamil Shuja ibn Aslam ibn Muhammad ibn Shuja) made an important link in the development of algebra between al-Khwarizmi and al-Karajis time not using the symbols, but writing powers of x in words, he had begun to understand what should be written in symbols. 852 [aviation, flight] Abbas Ibn Firnas (Armen Firman) made the first successful parachute fall near CÃÆ' ³rdoba, Spain using a huge wing-like cloak. 858 929 [astronomy mathematics] Al-Battani (Albategnius) made valuable works on astronomy, trigonometry etc.   860 Al-Farghani (Al-Fraganus) was master in Civil engineering and Astronomy. 864 930 [chemistry; medicine] Al-Razi (Rhazes) studied Astronomy, Chemistry, Medicine, Ophthalmology and Smallpox. He wrote on Naft (naphta or petroleum) and its distillates in his book Kitab sirr al-asrar (book of the secret of secrets). When choosing a site to build Baghdads hospital, he hung pieces of fresh meat in different parts of the city and selected the location where the meat took the longest to rot, for building the hospital. He also suggested that patients must not be told about their real condition so that fear or despair may not affect the healing process. His notable works were on soap, alkali, caustic soda, and glycerine. He also gave the descriptions of equipment, processes and methods for their preparation in his book Kitab al-Asrar (book of secrets) in 925.   870 950 Al-Farabi (Al-Pharabius) wrote on early Islamic philosophy, logic in Islamic philosophy, Muslim sociology, musical science and political science. In   875 [aviation, flight] Abbas Ibn Firnas made the first flight in a hang glider with artificial wings, but his landing was unsuccessful. He also worked on mechanics of Flight, Planetarium, and Artificial Crystals. Ibn Firnas was the first to investigate the means of flight.   800s [chemistry; petroleum] Oilfields in Baku, Azerbaijan, generated commercial activities and industry. These oilfields, were wells dug to get the Naft (or naphta, or crude petroleum) these were described by geographer Masudi in the 10th century and by Marco Polo in the 13th century, who described the output of those wells as hundreds of shiploads.   10th century: 900s [mathematics; accounting] By this century, three systems of counting were used in the Arab world. First was the Finger-reckoning arithmetic, in this system the numerals were written entirely in words this system was used by the business community. Second was the sexagesimal system, originated by the Babylonians, in this system the numerals were denoted by letters of the arabic alphabet it was used by Arab mathematicians in astronomical work. The third was the Hindu-Arabic numeral system, which was used with various sets of symbols. Arithmetic of this system required the use of a dust board (a sort of handheld blackboard) because the methods required moving of numbers in the calculation and rubbing some out as the calculation proceeded. Later these methods were modified by Al-Uqlidisi (born 920) for pen and paper use. Eventually the advances enabled the decimal system to be used throughout the world in its standard form.  

Get Smart: I.Q. and Emotional Intelligence Essay -- Biology Essays Res

Get Smart: I.Q. and Emotional Intelligence Intelligence is considered to be one of the most desirable personality qualities in today's society. Expectant parents are told to read and play music to the fetus, in order to stimulate its brain. Being bright is often thought of one the keys to success in life, and highly intelligent people such as Albert Einstein are celebrated. However, despite all the tests and criteria that measure intelligence, the question still remains: what is intelligence? How can it be measured? Is there only one kind of intelligence, or do humans possess several? These seemingly simple questions have proved to be some of the most perplexing and contentious topics in both public and scientific circles. Everyone differs in their ability to understand complex ideas, to adapt to the environment, to learn from experience, and to engage in various forms of reasoning. A person's intellectual performance can vary on depending on the occasions, environment, or criteria used to judge it. No current theory has been able to sufficiently answer all the critical questions or establish a consensus. The recognized method of measuring intelligence is the psychometric approach. It is the basis of I.Q. tests and other modern intelligence tests. However, a new theory called emotional intelligence has gained prominence with its more fluid and encompassing definition of intelligence. This has only added fuel to the debate over understanding and measuring intelligence. The psychometric approach was developed by Alfred Binet in 1904 to identify mentally retarded students who would benefit from special education. He designed the test to be an indicator of school performance and measured skills such as vocabulary, comprehe... ...act that all humans possess all these intelligences, everyone has different profiles of intelligences (6). Originally comprised of seven intelligences, its author, Howard Gardner, is considering adding naturalist and existential, because he feels it is necessary. One can only hope that others will see the necessity of a broader definition of intelligence.

Othello vs. Iago Essay

â€Å"Keep your friends close, Keep your enemies closer† Jealousy is a crazy thing. It can cause people to do unthinkable things. Most fights are over their jealousy of a person. In Shakespeare’s plays there is always a fight over this of some kind. Also written by Shakespeare, it is apparent in Othello. Two characters like Iago and Othello fight a silent battle except Othello has no clue about Iago’s powerful despise and envy to him. It is clearly evident that Othello symbolizes a hero while Iago adores the role as a villain. Their inconsistent characteristics are what separate the two from each other. Throughout the beginning Acts I and II of Othello, Othello and Iago differ greatly in their integrity and devotion towards others. Othello portrays himself as frank and sincere, while on the other hand Iago acts as the good guy but in the end backstabs the people who trust him. Othello demonstrates to his self and others his honesty. For example, when Othello explains to the Duke about their nuptials between him and Desdemona he nobly says, â€Å"That I have ta’en away this old man’s daughter, It is most true; true that I have married her† (I iii 93-34). Othello delineates his trustworthiness because he doesn’t try to keep the marriage a secret and tells the Duke up-front when he asks. In addition, he is straightforward to others when Iago warns Othello about Brabantio finding out about the marriage and tells him to go inside and he says, â€Å"Not i. I must be found. My parts, my title, and my perfect soul Shall manifest me rightly. Is it they?† (I ii 35-37). The general of the Venetian army is confident in himself that his service and stately fall will cause everything to calm down, he is also certain of his worthiness to Desdemona and that he deserves to have her and her love. Iago is pleased with his deceitful plans and sits back and savors the many lies he has told. For example, Iago shows his despise in integrity by whispering to himself that, â€Å"I am not what I am â€Å"(I i 71) and to Roderigo, â€Å"I follow him to serve my turn upon on him† (I i 45). Iago is acting like someone he is not to get the life he desires and is taking advantage of Othello just to proclaim his revenge for him and Othello does not know about it. Furthermore, when they defeated the Turks and decided to celebrate, Othello takes Desdemona up to their room, and Iago comes up with a plan for Roderigo to win back Desdemona by telling him, â€Å"Do you find some occasion to anger Cassio, either by speaking to loud or tainting his discipline, or from what  other course you may please, which the time shall more favorably minister† (II i 288-292). Iago is getting Roderigo to fight Cassio to dishonor him and is lying to Roderigo because he is telling him that this is how he can get Desdemona back but in reality Iago Is getting everyone who loves and trusts’ him only to turn them against each other for his own enjoyment. Integrity is shown through Othello because of his actions and the way he perceives difficult situations, but through Iago he displays no integrity to him or the others around him. While both of these characters may juxtapose in integrity they also greatly contrast in their devotion to the people in their life. Othello’s relationship with Desdemona is so affectionate and deep that he would do anything for her even though they had just recently wed. For instance, when Othello comes back from being lost at sea he shows his profound loyalty toward Desdemona by saying, â€Å"If it were not to die, ‘Twere now to be most happy, for I fear My soul hath her content so absolute that not another comfort like this Succeeds in unknown fate† (II i 205-209). If Othello were to die, he would die happy because he does not think that he will ever be as happy again, he believes that she is the only woman for him. In addition, he also proves his dedication to Desdemona when Brabantio tells Othello to keep an eye on her because Desdemona lied to her father and she might lie to Othello but in defense he says, â€Å"My life upon her faith† (I iii 335). Othello believes in Desdemona and is willing to bet his life on it and he would do anything for his wife just to show how much he loves her. Iago has malicious plans for getting revenge on Othello by committing his time in Roderigo so he can do his dirty work for him. For example, Iago takes advantage of Roderigo’s vulnerability over Desdemona getting married to Othello when Roderigo is in love with her by scheming up a plan for him to, â€Å"Put money in thy purse Follow thon the war; defeat thy favor with an usurped beard† (I iii 382-384). Iago’s continued pursue of Roderigo’s trust displays his dedication to Othello’s downfall and Roderigo’s foolishness allows Iago to trick him into doing absolute ly ridiculous favors and giving him more money â€Å"for Desdemona†. In addition, Iago hates Othello for various reasons and he says that, â€Å"in following him, I follow but myself. Heaven is my judge not I for love and duty but seeming so for my peculiar end† (I i 64-66). Iago manifests the fact that he despises the Moor although Othello has not committed anything against him  knowingly and perseveringly pursues Othello to bring about his collapse. Othello and Iago both compare in their dedication towards others but not for alike reasons. Throughout the beginning of the story, Iago and Othello develop distinct characteristics that show differences between them. Iago is always trying to hinder the moor, while Othello continues his expression of honest virtues. Iago relishes his deceit and manipulation of others, rather than to show he is a leader. These two show a part of life that will never go away. There are multiple differences between Othello and Iago but they both share a comparison in knowledge and understanding.

Laissez-faire: Supply and Demand and Demand Curve

TASK 1 Laissez-faire Laissez-faire is an economic environment in which transaction between private parties are free from tariffs, government subsidies, and enforced monopolies, with only enough government regulation sufficient to protect property rights against theft and aggression. The phrase laissez-faire is French and literally means â€Å"let them do†. But it broadly implies â€Å"let it be†, or â€Å"leave it alone†. A laissez-faire state and completely free market has never existed, though the degree of government regulation varies considerably. The basic characteristics of Laissez-faire economic systemFree competition The main body of the economic operation is for a large number of small private enterprises. Production and management strategies are made by private capitalists according to changing in market supply and demand. Private capitalists are free to participate or exit the economic activity of any of industries. The form of price is spontaneous in market. It shows the change of supply and demand, it can distribute the scarce resources to producers, and also distributes goods and services to consumers. Consumer rights Consumers are the main part of economic operation.Consumer rights show: private capitalists must be base on and consider the preferences of consumers in the coordination of production and management strategies. According to consumers in the market, the number of monetary voting (consumers use their own money to purchase their favorite products, it is also another form of voting), and understand the social consumption trends. Thus distributes human and material resources, financial resources, production and meet consumers demand to achieve the purpose of maximum profit. Consumers are the guidance of economic activity through the function of preference for certain goods and services.Protecting of government Laissez-faire economic activities and resource allocation by the market mechanism to promote, the country or the government's economic functions are restricted to the protection of free competition, protection of private property, set up some necessary public utilities and public facilities. The components are absence to function an idealized free market. The problems mainly in the following aspects: 1. The competition between enterprises is limited, and some may be a monopoly industries. In these cases, they will push up prices, up profits. 2.The lack of competition to promote efficient and profitable company†¦ 3. Power and wealth may not equal distribution. 4. Some of the company's behavior is harmful to the society. 5. Private enterprise will not produce some of the whole society to their own advantage but without the product. 6. The free market economy could lead to macroeconomic instability, may appear high unemployment and production of the decline of the recession and rising prices. TASK 2 Government intervention in the market can be used to achieve various economic objectives which may not be best achieved by the market.There are several policy instruments that the government can use. At one extreme, it can totally replace the market by providing goods and services itself. At the other extreme, it can merely seek to persuade producers, consumers or workers to act differently. Between the two extremes the government has a number of instruments, it can use to change the way of markets operating. These include taxes, subsidies, laws and regulatory bodies. Taxes and subsidies When there are imperfections in the market, social efficiency will not be achieved. Marginal social benefit will not equal marginal social cost.A different level of output would be more desirable. Taxes and subsidies can be used to correct these imperfections. Essentially the approach is to tax those goods or activities where the market produces too much, and subsidies those where the market produces too little. Taxes and subsidies correct externalities. Government imposes a tax equal to the marginal external cost, grant a subsidy equal to the marginal external benefit. Taxes and subsidies are to correct for monopoly. If the problem of monopoly that the government wishes to tackle is that of excessive profit, it can impose a lump-sum tax on the monopolist.A tax of a fixed absolute amount irrespective of how much the monopolist produces, or the price it charges. Advantages of taxes and subsidies It forces firms to take on board the full social costs and benefits of their actions. It is also adjustable according to the magnitude of the problem. What is more, by taxing firms for polluting, firms are encouraged to find cleaner ways of producing. Disadvantages of taxes and subsidies Infeasible use different tax and subsidy rates. Lack of knowledge. Laws prohibiting or regulating undesirable structures or behavior Laws are frequently used to correct market imperfections.Laws can be of those main types: those that prohibit or regulate behavior that imposes external cost s, those that prevent firms providing false or misleading information, and those that prevent or regulate monopolies and oligopolies. Advantages of legal restrictions When the danger is very great, it might be much safer to ban various practices altogether rather than to rely on taxes or on individuals attempting to assert their property rights through the civil courts. Disadvantages of legal restrictions The main problem is that restrictions tend to be a rather blunt weapon.Regulatory bodies Rather than using the blunt weapon of general legislation to ban or restrict various activities, a more â€Å"subtle† approach can be adopted. This involves the use of various regulatory bodies. Having identified possible cases where action might be required, the regulatory body would probably conduct an investigation and then prepare a report containing its findings and recommendations. It might also have the power to enforce its decisions. The advantage of such bodies is that a case-by -case approach can be adopted and, as a result, the most appropriate solution adopted.However, investigations may be expensive and time consuming only a few cases may be examined, and offending firms may make various promises of good behavior which may not in fact be carried out owing to a lack of follow-up by the regulatory body. Price controls Price controls can be used either to raise prices above, or to reduce them below, the free-market level. Prices could be raised above the market equilibrium to support the incomes of certain supplier. Prices could be lowered in order to protect consumer’s interests. The direct provision of goods and servicesSocial justice, society may feel that these things should not be provided according to ability to pay. Rather they should be provided of right: an equal right based on need. Large positive externalities, people other than the consumer may benefit substantially. TASK 3 To avoid fluctuation of inflation, the related policies of gover nment are monetary policy, Fixed exchange rates, Gold standard, Wage and price controls, cost of living allowance. Monetary policy Central banks must be keeping their inter-lending rates at low levels. To target rate is around 2%-6% per year.Government can avoid inflation through setting interest rates. High interest rates and slow growth of the money supply are the traditional ways, central banks prevent inflation. Keeping the growth rate of money steadily, and using monetary policy to control it, increasing interest rate, slowing the rise in money supply. Encourage people to put money in the bank. To reduce the number of money circulation. According to Keynesian, reduces aggregate demand when the economic is expanding, and increases demand to keep inflation stable. Increase taxes or reduce government spending.Fixed exchange rates Under fixed exchange rates, a country's currency is tied in value to another single currency. This essentially means the inflation rate in the fixed exch ange rate country is determined by inflation rate of country. Fixed exchange rate prevents a government from using domestic monetary policy in order to keep economic stable. Gold standard The gold standard is a monetary system in which a region's common media of exchange are paper notes that are normally freely convertible into pre-set, fixed quantities of gold.The standard specifies how the gold backing would be implemented, including the amount of specie per currency unit. The gold standard was partially abandoned via the international adoption of the Bretton Woods System. Under this system all other major currencies were tied at fixed rates to the dollar, which itself was tied to gold at the rate of $35 per ounce. In the gold standard system, the internal value of currencies and external value in general is consistent, currency exchange between is stable and the exchange rate also have relatively solid foundation.Wage and price control Wage and price control is also called Income policy, Income policy mainly is to take wage price management policy, in order to prevent trade unions and the two groups monopoly enterprises still each other caused by the wages, prices take turns to the rising trend. Its purpose is to tries to control inflation and not lead to increased unemployment. Incomes policy based on the theory of main is pushed by cost inflation, because cost inflation is pushed by because of the rising cost of supply, especially wage increase, thus cause the price level to rise.Therefore, we must take inhibits the incomes policy, the form has the following kinds: sure wage-prices will, in order to limit wages-prices to rise. Base on compulsory measures, impose income tax policy. Cost of living allowance Keep the general level of commodity prices steady, strict control prices, the incomes of the workers and living allowance, reduce the cost of their life, so as to control income and the increased cost of products. The relationship between inflation and e mployment Demand-pull inflation When aggregate demand exceeds aggregate supply, will cause the general price level continued to rise.From Philips curve, we can understand that, when aggregate demand is greater than aggregate supply, in order to meet aggregate demand in the short term, we can increase aggregate output to provide more employment. TASK 4 Supply –Demand curve Supply Supply is to point to a producers in other conditions remain unchanged, at one time, ability and willingness to for a price to market with the amount of products. A supply schedule is a table that shows the relationship between the price of a good and the quantity supplied. A supply curve is a graph that illustrates that relationship.The supply curve is supply table and supply the visualization expression, and demand form or demand function of handing over the equilibrium, is used to represent the market producers and demanders can constitute a trade goods quantity and price. The supply curve can with â€Å"curve† appeared, also can use the â€Å"straight† form. In theory, meet the supply curve only supply theorem can be tilted to the upper right. The determinants of supply follow: 1. Production costs, how much a good costs to be produced 2. Technology used in production, and/or technological advances 3. The price of related goods . Firms' expectations about future prices 5. Number of suppliers Demand Demand is to point to a consumer in other conditions remain unchanged, within certain time, ability and willingness to buy in a given price of the product quantity. The demand curve is demand form and demand function expression of visualization, and supply table or transfer the equilibrium of supply function, which is used to represent the market producers and demanders can constitute a trade goods quantity and price. The demand curve can with â€Å"curve† appeared, also can use the â€Å"straight† form.In theory, can meet the requirement of the demand c urve can only theorem is right to tilt, so Veblen Goods and Giffen Goods are general demand curve is not those from left to right leaning items. The determinants of demand follow: 1. Income 2. Tastes and preferences 3. Prices of related goods and services 4. Consumers' expectations about future prices and incomes 5. Number of potential consumers Equilibrium Equilibrium is about the price-quantity curve, it means the quantity of supply is equal to the quantity of demand.In the market, when the price is given, the quantity of products that consumers demand is balanced by the quantity of products that producers supply. Demand curve shifts At each price point, greater quantity is demanded, the curve from D1 to D2, at the same time, the equilibrium price from P1 to P2, and the equilibrium quantity from Q1 to Q2. There is an increase in demand which has caused an increase in quantity. The increase can also come from changing tastes and incomes, price changes in complementary and substitut e goods, market expectation, and number of consumers.If the demand decreases, the situation is opposite, the demand D2 down to D1, the equilibrium price decreases, and the equilibrium quantity also decreases. The quantity supplied at each price is the same as before the demand shift, reflecting the fact that the supply curve has not shifted; but the equilibrium quantity and price are different as a result of the change in demand. Supply curve shifts When the supply of a product decreases, curve from S1 to S2, it makes the equilibrium price decreases from P1 to P2, but the equilibrium quantity increases from Q1 to Q2.If the quantity of supply decreases, the curve will from S2 to S1. The equilibrium price will increase and the equilibrium quantity will decrease as consumers move along the demand curve to the new higher price and associated lower quantity demanded. Partial equilibrium Partial equilibrium as the name suggests takes into consideration only a part of the market, ceteris p aribus to attain equilibrium. Partial equilibrium is based on a limited range of data, a standard example is the price of a single product, all other prices of the products in a fixed analysis.The supply and demand model is a local equilibrium model of economic balance, clear the market prices of the goods and some specific number won independence in other markets. In other words, the prices of all the alternative and complementary, and income level of consumer is constant. Partial equilibrium analysis testing these policy actions in the influence of creating balance in the industry or market only specific directly affected, ignore its effect in any other market or industry that they were small almost no influence. AD-AS model (Long-term equilibrium)AS is long-term total supply curve, it and potential output line entirely coincidence, when the total demand curve to AD, total demand curve and long-term total supply curve intersection of the decision's production for Y E, price level for P. When the total demand increased total demand curve from AD move up to the AD, total demand curve and long-term total supply curve intersection of the decision's production for Y E, price level for P, because Y = Y = Y *, so in the long run of total demand is growing only raised the price level, and won't change the production or income. TASK 5 Market Demand for Coffee Form of D0 Price| 1. | 0. 75| 0. 5| 0. 25| Quantity| 9| 11| 12| 14| Form of D1 (Price same as D0) Price| 1. 5| 0. 75| 0. 5| 0. 25| Quantity| 7| 8| 9| 10| Form of D1 (Quantity same as D0) Price| 0. 5| 0. 2| 0. 1| 0. 05| Quantity| 9| 11| 12| 14| If we define D0 is the initial demand curve. When demand decreases, D0 will leftward to D1. We can understand from above form, when D1 same as D0 in price, quantity of D1 is decreased; when D1 same as D0 in quantity, price of D1 is decreased. So the equlibrium of D1 is also decreased. ( the quantity and the price are decreased at the same time) Form of D2 (Price same as D0 ) Price| 1. 5| 0. 75| 0. 5| 0. 25|Quantity| 11| 13| 15| 17| Form of D2 (Quantity same as D0) Price| 3| 1. 5| 1| 0. 75| Quantity| 9| 11| 12| 14| If we define D0 is the initial demand curve. When demand increases, D0 will rightward to D2. We can understand from above form, when D2 same as D0 in price, quantity of D2 is increased; when D2 same as D0 in quantity, price of D2 is increased. So the equilibrium of D2 is also increased. (the quantity and the price are increased at the same time) Factors that affect the demand for coffee Consumer income. Generally speaking, in other conditions of constant, the higher the income of consumers, the more demand for commodities.So the quantity of coffee high income consumer demand is more than the quantity of coffee low income consumer demand. Consumer preferences. When consumers of some goods of preference increased, the demand for the goods number will increase. Instead, when of preference abate, demand will reduce the number. So the quantity of coffee demand that people like coffee is more than the quantity of coffee demand that people don’t like coffee. The price of related products. When the price of a commodity itself is fixed, but and it related to other commodity price change, this kind of goods is the number needs will also be changing. o a commodity demand and alternatives to price but change, namely substitutes the increase in the price of the commodities will cause the increase of demand, the price will reduce substitute caused the reduction of the demand for commodities.

sex vs gender essays

sex vs gender essays A person is born either male or female, however according to Mead the roles of males and females are conditioned by that person's given culture. There were two articles studied by Group D, the first one tries to prove that men or women can be the aggressive sex, while the second article deals on which sex talks more and why. What it comes down too is, that both articles try to distinguish which sex is more dominant and why. Margaret Mead article, "Sex and Temperament in Three Primitive Societies," describes research done to see if cultures contribute to the shaping of a person. The research done involves three primitive groups, the Arapesh, the Mundugumor, and the Tchambuli. IN each of the groups the roles of the sexes , both males and females, were based on the culture conditioning rather genetics or heredity. For example, culture conditioning the way a new born child is shaped into its given culture. The three groups that research was done on, at a specific point in time the child is assigned personality traits which include feminine or masculine and also the manners of the child are established. The results differ from the three groups, for the Arapesh, the individual was mildly responsive, for the Mundugumor, both male and female were aggressive and violent, and for the Tchambuli, the women dominant and the men were emotionally dependent. The reason why the results were different for all thr ee is different cultures leads to different cultural conditioning. The second article written by Deborah Tannen, "You Just Don't Understand: Women and Men in Conversation", deals with communication among men and women. The article attempts to explain why women and men talk when the do. The article states that women have been punished for talking too much or talking in the wrong way. Women have also been stereo typed since Colonial America, which different punishment were given to women. For example, wo ...

Can choose from three Essay Example | Topics and Well Written Essays - 1000 words

Can choose from three - Essay Example According to Nagel, reductive arguments seek to explain a phenomenon in terms of objectivism hence it omits the essential of the conscious experience, which are subjective. Because of this, Nagel believes that the whole idea of objective does not add up or make sense. Nagel also believes that the conscious experience is about one’s interpretation and varies with people. It is like asking someone else what he or she thinks about something. In this case, one is entitled to say what he or she feels and whatever said is welcomed. Therefore, it is valid for Nagel to argue that the conscious is interpreted in terms of subjectivism. It is not always possible for the majority to see or view a phenomenon like an identical twins; the differences must be embraced and accommodated. Nagel chose the example of a bat to validate his information because of many things. First, bats resemble man to some extent. Similarly, there are rhetorical elements in his choice of bats since they have a traditional reputation of being weird, and some have special senses that humankind do not have. They are essential in persuading people that do not think others can reason the same way. Similarly, bats have experiences that man does not have. Hence, there is a limit to human understanding that makes consciousness very difficult to understand. It is also important to consider the situation and conditions of an organism that influences one’s consciousness. For example, Nagel argues that facts about what it is to be an organism conscious state is accessible only from certain points of view. A dead human being no longer reasons because she or he does not have any point of view. Similarly, a drunken person has a different viewpoint from the way sober people reason. Although a drunken is also a human being, the conscious mind that reason is not supported by alcohol but influences it towards giving unwarranted reasoning. The logic that one gives determines consciousness and all that pertains to

British Isles Iron Production during the Roman Occupation Essay

British Isles Iron Production during the Roman Occupation - Essay Example The essay "British Isles Iron Production during the Roman Occupation" talks about the evidence concerning the chain of operation in iron production in the British Isles during the Roman occupation. The British Isles were clearly a vital part of the Wealden iron industry having been in operation from pre-historic periods. Considering that its geology that was made up of sandstone Ashdon Beds and clay mad it easier for the extraction of iron. The place was also favorable in that there was enough wood that would be used during the smelting process. Furthermore, the soft sandstones could be carved to form valleys and lakes that would eventually provide water for powering the forges and furnaces. The process of identifying the iron mines depended on the availability of wood used for smelting fuel which was abundant in the British Isles. This was because iron ores were found everywhere in the country and iron quite inexpensive. Britain emerged to be a right place for getting iron which was required for making war machines used by the Romans. The Romans constructed most f the underground mines found in Britain. Iron was mined in open pits as well as underground fields with slaves bearing the weights of the work. After extracting the ore from the mine it was the crushed and washed according to Burnham. Once the iron ore had been mined from the open pits, they had to be cleaned before undergoing further processing. The iron oxide was then left after washing and later was smelted through the bloomery method.
