Pregnant women who have more exposure to higher pollution areas are at Essay

Pregnant women who have more exposure to higher pollution areas are at more of risk for having children with autism - Essay Example This is the most recent in several similar studies to suggest this although it is the first national study. The suspect agents include diesel exhaust, mercury, manganese, lead, methylene chloride and nickel. Pollutants of this nature present in the atmosphere pose a higher risk to mothers in these areas for giving birth to children with autism. Mercury and diesel exhaust were found to pose the highest risk. Other researchers argue that there is a higher risk of autistic children being born to mothers living in areas polluted with several industrial pollutants. Windham et al. (2006), suggested that a potential association exists between autism and other elements of environmental pollution such as metal particles and possible solvents in the atmosphere. Pregnant women who lived near San Francisco bay and exposed to environmental pollutants were susceptible to autism spectrum disorders. This is due to the particulate matter in air and vaporization of mercury from asphalt during hot weather causing increased exposure to higher than normal levels of contamination. Windham et al. (2006) suggested that areas with increased concentrations of hazardous pollutants are at more risk of experiencing autism disorders. This also occurs along the west coast where there are increased ambient levels of particulate pollutants blown in from Asian countries that are the largest producers of these pollutant s from coal burning in power production plants. These pollutants are neurotoxins that cross the placental barrier to the baby during development in the womb and cause genetic changes leading to defective genes. These genes disrupt brain development by causing a breakdown in the process in the fetus and cause autism. According to Kalkbrenner et al., (2014), this may also be by retarding natural nervous system development or by hindering immune cells from assisting more efficient neuron

Discuss the view presented by Nasim and Sushil (2011) that managing Essay

Discuss the view presented by Nasim and Sushil (2011) that managing change invariably involves managing paradoxes and in partic - Essay Example This view of organisation change’s reality indicates a postmodernist oncology, where change remains fluid and elusive. As a result, to understand it demands acknowledging and accepting its dynamic, fluid nature. Managing changes requires managing paradoxes through a postmodernist ontology with postconstructivist epistemology because of the existence of diverse types of changes, resistance to changes, and narratives for attaining individual and organisational changes. The paradox of change lies in the postmodernist ontology with postconstructivist epistemology. Postmodernist thinking on the study of being views reality as a combination of different ways of seeing. The study of organisational changes has intersected various concepts from diverse fields, such as child development and evolutionary biology, and yet not many scholars have integrated them in a systematic manner (van de Ven and Poole, 1995: 510). Poggie (1965: 284) remarks on the paradox of knowing reality: â€Å"A w ay of seeing is a way of not seeing.† One epistemological view of reality is one way of not seeing reality through another perspective. van de Ven and Poole (1995: 511) urge for an interdisciplinary approach to seeing the reality of organisational change: â€Å"It is the interplay between different perspectives that helps one gain a more comprehensive understanding of organisational life, because any one theoretical perspective invariably offers only a partial account of a complex phenomenon.† They promote a postmodernist view of seeing and knowing the reality of organisational change because it enriches its understanding. Furthermore, the paradox-of-change approach uses postconstructivist epistemology using competing theories to explore and to illustrate it. van de Ven and Poole (1995) offer a typology of process theories that examine how and why change happens in social or biological units. These are life cycle, teleological, dialectical and evolutionary process theor ies. These four theories stand for essentially different event chains and generative components that they called â€Å"motors† to depict the processes and causes of changes (van de Ven and Poole, 1995: 511). van de Ven and Poole (1995) stress that organisational change do not neatly fit only one of these process theories because some conditions can stimulate interdependent changes across different organisational elements. They stress the complexity of changes: â€Å"Even though each of these types has its own internal logic, complexity and the potential for theoretical confusion arise from the interplay among different motors† (van de Ven and Poole, 1995: 534). The paradox of changes arises from the reality of spontaneous effects of changes, anticipated or otherwise. Sturdy and Grey (2003) criticise the one-sided view of organisational change management (OCM) discourses that emphasise stability over changes. They offer different views of changes using discourse analysi s. They conclude the need for using different lenses in understanding changes and in attaining effective changes. Hence, this essay finds it useful to see changes from a postmodernist view of organisational reality and knowledge. The paradox of change and continuity affects different kinds and stages of changes. Managing changes in different types of changes require balancing change and continuity. Nadler and Tushman (1989) examined diverse large-scale organisational changes and provided several insights and generalisations. They reviewed

Homework9 Essay Example | Topics and Well Written Essays - 500 words

Homework9 - Essay Example Separation of power identifies three power centers that are necessary for offering checks and balance on each other. The branches are the Congress, the executive, and the Judiciary. The President heads the executive whose roles, besides primary roles, are to offer checks and balances on the judiciary and the Congress. The Congress is the law making body in the nation and the president has the duty to assent to made laws before they can become effective and to veto laws that may be repugnant to natural justice and this ensures that only rational laws that the Congress enact govern the people. The president also plays an important role in appointment of judges through nominating them and this ensures good conduct in the judiciary. The Judiciary is also necessary because of its checks on both the executive and the Congress. Like the executive, it can declare legislation unconstitutional and therefore render it invalid and this ensures that the Congress does not just make arbitrary laws. The Judiciary can also declare actions and decision of the executive unconstitutional to minimize arbitrary authority. The congress is also necessary because of its regulatory powers over the executive such as disapproving a bill that the president prefers, passing a law contrary to the president’s veto, impeaching the president, and refusing to approve the president’s recommendations that are subject to the Congress’ approval. In addition, the congress is necessary for its checks over the courts such as impeachment of judges for misconduct, refusing to approve appointment of a judge, and varying jurisdiction of a judge. Federalism is also necessary for checks and balances by the federal and state governments on each other (Wilson, Dilulio and Bose 31). The nation has an inefficient political system because of the mode of appointment to the political offices.

How significant are trade unions in Britain today Essay

How significant are trade unions in Britain today - Essay Example In Britain, trade unions have been instrumental in promoting cooperation between management and workers throughout the history. However, the situation does not seem as favourable in today’s working environment. The paper examines the significance of trade unions in today’s Britain and concludes that trade unions have lost their influence in modern workplace due to increasing employer concern and direct voice of employees. With the closure of twentieth century, trade unions have to experience the challenge to deal with the issues which were considered to be resolved. Today’s trade unions are not as influential as they were in past. The period 1945-75 was exceptional because of the high tide of union power. However, unions represent significant and influential interest and the nature of their role and process of change is intensively debated (Mcllroy, 1995, p.385). Approximately 13.3 million people were members of trade unions in 1979; it is the highest level ever reached in Britain for union density at 55.4 percent. Impact of industry level bargaining and wage councils refer to 85 percent of working population catered by collective pay-setting process (cited in Howell, 2005, p.131).Furthermore, with the end of 2001,union membership level declines by 40 percent to 7.6 million, union density reached the lower level of 30 percent of workforce (cited in Howell, 2005, p.131). From 1980s to 1990s, there is a distinct diversion from closed shop to simple recognition (Fernie, 2005, p.5).In a statistical analysis, Millward et al. (2000, cited in Fernie, 2005, p.5) inferred that major reasons of decline in union density in unionised workplace were decline in closed shop and membership endorsement from management during 1984 and 1990.However, situation appeared to be different during 1990 to 1998 when employees appeared to have lost their interest in unionism(Fernie, 2005, p.5). Today, 1970’s steep decline in union membership seemed to be halted ; however, decline in collective bargaining has experienced their conventional impact in the workplace wane. Most unions are as concerned about upholding and reinforcing individual legal rights of their members as for the development of collectively bargained rights. Comparatively less discussed but just as crucial is the relative decline in the membership of different employer’s organizations (Donaghy, cited in Taylor, 2002, p.5). Considerable revival in union membership at the point of late 1970s when 58 percent of workers were union members appeared to be improbable. De-industrialization has stripped the earlier bastions of trade union power in textile, coal, steel, iron, engineering and shipping. Central driver for dramatic union growth during 1960s and 1970s, the public service sector, is not anticipated to flourish like past. With the termination of broader bargaining agreements, more personalized forms of wage negotiations at enterprise level countermined the role of t rade unions and ceased them to perform their conventional role of collective negotiators. Furthermore, trade unions are not benefitting by their role as collaborator in the management of political economy (Taylor, 2002, p.6). Today, their role outside the workplace is less enunciated and more challenged as compared to the initial times after Second World War. Illegalizing closed

Teachers and Ethics Responsibilities Essay Example | Topics and Well Written Essays - 1500 words

Teachers and Ethics Responsibilities - Essay Example On the other hand, this contravenes school policy, which gives the child’s parents a right to participate in such decisions. Part 2: Application of different ethical approach theories Each of the options that present themselves to Elizabeth in this situation has an ethical value if assessed using different perspectives. Choosing to proceed with counseling sessions without the parents’ consent can be validated as ethical under the consequential view. This will have a likely positive outcome, as it will eliminate Trevor’s misconduct. In addition to this, it protects him from abuse by his parents who would more likely than not exact their own means of punishment on learning about Trevor’s behavior. The fact that prior evidence indicates a sustained trend of such response from Trevor’s parents gives the ethical value of this option much substance. On the other hand, this option cannot be justified under the non-consequential view of professional ethics. This is because the very act in itself undermines the rights of Trevor’s parents to choose a suitable method of discipline for their child. There are non-consequential ethics with the second approach to inform Trevor’s parents about the stealing incident and counseling sessions. ... The non-consequential approach The non-consequential theory evaluates the ethical nature of an action based on its value (Freakly & Burgh, 2000). The assessment of the act is on terms of what it directly implies. Certain kinds of acts are immediately dismissed as unethical and others as ethical. There is a static and clear classification in this case since there are some merits in taking the non-consequential approach to judge ethical value. One advantage of the non-consequential approach is that it preserves the importance of professional duty. In a sense, it puts a set of unchanging values that come with taking up a certain professional position forward (Preston, 2007). Allowing exceptional cases to have alternative consideration creates room for past reference in the future, which may complicate the judgment of similar cases once they arise. Another advantage is the protection of the rights and freedoms of people. In a non-consequential scenario, the rights of an individual are co nsidered values that bear as much weight as the gain construed from seeking a positive outcome from a decision. Though the non-consequential theory has advantages of a static nature, it prevents progress on many levels. The creation of a system to uphold rights is essentially going to give precedence of such rights over social development, which would include changing the child’s behavior and changing the parents’ view on non-violent discipline. The consequential approach The consequential approach judges an action’s rightness based on the outcomes of its implementation. If the outcomes of taking an action prove to be positive, then that action is judged as right, and if it is negative, then it is

More Import Permits If Not Enough Chicken Essay Example for Free

More Import Permits If Not Enough Chicken Essay JITRA: The government will issue permits to import chicken only if there is a shortage. Deputy Agriculture and Agro-based Industry Minister Datuk Johari Baharom said this was unnecessary at the moment as there was a sufficient supply. There are enough chickens to meet demand for the fasting month and Hari Raya , he said after having sahur (predawn meal) with villagers in Kampung Teluk Malek here yesterday. The local chicken farms produce between 1.4 million to 1.5 million birds per day and demand for chicken is less than 1. 4 million daily. The government will monitor the supply of chicken to avoid any shortage in the market, especially during the festive season. He said the farm price of RM4.70 per kg imposed since the beginning of the fasting month was reasonable, especially when compared with price in neighboring countries. He added that transportation costs and increase in demand were the contributing factors to price increase. Adapted from New Straits Times, August 16, 2010 a) What is market equilibrium?

History of the concept of creativity

History of the concept of creativity History of the concept of creativity In spite of its current popularity, the concept of creativity, i.e. its name, is a recent notion that, nevertheless, went through a number of development stages and metamorphoses caused by the changes in the way the concept of creativity was perceived by societies at various stages of development. The process is not finished yet. Sometime in the future the general concept of creativity will hopefully be converted into a specialized concept, i. e. its regularities will be enumerated while its particularities linking it currently to a culture or a subculture will be eliminated. In the following text, the evolution of the concept of creativity throughout history is reviewed briefly, with the focus on important milestones and personalities. The milestones are arranged in a temporal sequence, whereas outstanding personalities are quoted where necessary, rather than presented in a strict temporal sequence. It is intuitively easy to accept the thesis that creative acts have been around as long as the homo sapiens, the humanoids and, indeed, living organisms. The concept of creativity appeared much later, and came forth very gradually. On the long way to establishing it, many intermediate new terms were generated, some of which have been used for centuries, in exceptional cases until our time. They help us understand more easily what creativity is and how it interacts with other operations in the intellectual sphere. Theoretical views of creativity follow the development of human culture and thought. Therefore, the concept of creativity is a component of the history of the human thought to the same extent as any other intellectual manifestation (Briffault, 1928). Much of the historical developments as accounted for in the following review are based on Tatarkiewiczs book (1980), Dictionnaire philosophique, and the following references: Verma (1969), Lindberg (1976), Abdus Salam (1984), Agar (2001), Ahmad (2002), Steffens (2006), Covington (2007), Roshdi (2007), and Medieval Classic civilization; An Encyclopaedia. Prehistoric times Remarkable and very advanced objects testifying to human creative genius are known from the art history. They originate from many parts of the world and from many different cultures and epochs. Perhaps the foremost examples of the earliest manifestations of creativity are various objects produced by the Australian Aborigines. The Aborigines are presumed to have moved to Australia from India some 50 000 years ago. Their most puzzling creative product is the boomerang for them hunting tool, for us an enigmatic object of scientific studies. Other important manifestation of human creative act and thought originates from Egypt and Mexico. These countries distinguish themselves not only by very advanced ability to produce objects, but also by the scientific (most often astronomic) knowledge embedded in these products. The pyramids of Egypt and those of Mexico, Guatemala, or Belize, the Mayan calendar, and the way of using mathematics in Egypt and in Mexico, are absolutely amazing even today. The Mayan astronomers had developed a spatial geometry parting from astronomy. The mathematics they used is still more accurate than the computational algorithms that make the flow of data in modern information networks possible (Ferrera-Balanquet, 2009). Another cultural area of great importance extends in Asia, particularly in the area comprising the present day Iraq, Iran, India, Sri Lanka and Cambodia. Buildings, materials and various concepts of physics embedded in the buildings testify to the high level of knowledge these peoples possessed thousands of years ago. In China and Japan, too, creativity enhanced knowledge in a manner that after thousands of years is still admired. India stands, as usual, apart in that it knew creativity as â€Å"insight† since times immemorial. For instance, in the extinct Pali language the word vipassanÄ  consists of the Sanskrit prefix â€Å"vi-â€Å" and the verbal root à ¢Ã‹â€ Ã… ¡paņº. It is often translated as †insight† or â€Å"clear-seeing,† One should not be misled by the â€Å"in-â€Å" prefix in â€Å"insight†.. â€Å"Vi† in ancient Aryan languages is equivalent to the Latin â€Å"dis-†. It is reasonable to conclude that in the word vipassanÄ  the prefix â€Å"vi-† generates the meaning â€Å"to see apart†, or discern. Alternatively, the â€Å"vi† can function as an intensifier. In that case vipassanÄ  may mean â€Å"seeing deeply†. A pali synonym for â€Å"VipassanÄ Ã¢â‚¬  is paccakkha, menaing â€Å"before the eyes,† which refers to direct experiential perception. Thus, the type of seeing denoted by â€Å"vipassanÄ Ã¢â‚¬  is that of direct perception and experience, as opposed to knowledge derived from reasoning or argument. It has also been adopted as the name of a kind of Buddhist meditation. Ancient Greece The people of Ancient Greece had no terms corresponding to â€Å"creativity† or â€Å"creator†. Yet, the poet was considered to be one who creates. Whatever was â€Å"creative† in the present sense of the word, was called art. The concept of art (in Greek  Ã…  Ã‚ Ã‹Å" Ã‚ Ã¢â€š ¬Ã‚ ¼Ã¢â€š ¬Ã‚ °, from which technique and technology evolved), implied subjection to rules. Poetry (from  Ã¢â‚¬Å¡Ã‚ Ã¢â€š ¬Ã¢â€š ¬Ã‚ ´Ã‚ Ã¢â€š ¬Ã¢â€š ¬Ã‚ ´Ã‚ Ã†â€™Ã…  Ã¢â€š ¬Ã‚ ¼ to make) was an exception, although it was limited only to  Ã¢â‚¬Å¡Ã‚ Ã¢â€š ¬Ã†â€™Ã…  Ã¢â€š ¬Ã‚ °Ã‚ Ã¢â‚¬  Ã¢â€š ¬Ã‚ ´Ã‚ Ã‹â€  (poetry) and to the  Ã¢â‚¬Å¡Ã‚ Ã¢â€š ¬Ã¢â€š ¬Ã‚ ´Ã¢â€š ¬Ã‚ °Ã‚ Ã…  Ã‚ Ã… ¡Ã‚ Ã‹â€  (poet, or maker) who made it, rather than to art in general. The reason was that art was considered an imitation of what already exists, â€Å"the making of things, according to rules†, hence subjection to laws and rules. In painting, music, or literature, there was no freedom. They were governed by what was known as ÃŽÂ ½ÃƒÅ½Ã‚ ¿ÃƒÅ½Ã‚ ¼ÃƒÅ½Ã‚ ¿ÃƒÅ½Ã‚ ¹ (the laws). This conservative attitude and need for subjection prevailed in the works of Plato who claimed, mainly in Timaeus, Dialogue of Ion, and in The Republic, that a good work is contingent on observing an eternal model as suggested by Nature, and never deviate from that model. The eternal models were within reach, in the surrounding world, of which artists were the imitators. They thus had to abide by certain rules. In the visual arts, freedom was curtailed by the proportions that Polyclitus had established for the human frame. He called them â€Å"the canon† (meaning, measure). Likewise, in music, no freedom was necessary because melodies for ceremonies and entertainme nt were known. They were prescribed as nomoi. Making of things according to rules, or à Ã¢â‚¬Å¾ÃƒÅ½Ã‚ µÃƒ Ã¢â‚¬ ¡Ãƒ Ã¢â‚¬ ¦ÃƒÅ½Ã‚ ·, was not considered to contain any creativity at all. In fact, if they had contained creativity, the state of affairs would be considered bad by the Greek standards of that time: Something similar to the negative perception of creative accounting nowadays [Tatarkiewicz, 1980, p. 244]. Man ought to discover the laws of Nature and abide by them. Seeking freedom of action unnecessarily distracts him from seeking the optimum way. In Ancient Greece the artist was not an inventor, he was a discoverer [Tatarkiewicz, 1980, p. 245]. It means that he had to study the laws of Nature, discover and see how related entities interact, and use them as a model. This world-view had its own justification. Nature is both perfect and subject to laws. The artists ambition must be to discover these laws and submit to them, rather than seek the distracting freedom from these laws, a freedom that would deflect him from attaining the optimal state. Poetry stood outside these limitations. The poet invented a whole new world and gave it life. The poet differed from the artist, the imitator, in that laws did not bind him. In spite of the absence of the term for creativity, creation, or the creator, the poet, and only the poet, was understood to be a creator.According to the Greek view, the poet was an inventor, i. e. he put together unrelated entities and let them interact in an arbitrary manner. This is what made poetry the only exception from the rules applying to art. In terms of truthfulness of this world-view, Aristotle, who established the term truth, was not sure whether poetry required adherence to truth, i. e. whether it imitated Nature. He thought that poetry was in the realm that was neither true nor false [Tatarkiewicz, 1980, p. 245-6]. The concepts of imagination and inspiration, too, were restricted to poetry only. Poets were seen differently and they saw things differently. But not everybody was reconciled with this restriction. An example can be found in the Odyssey, where a question is posed why the singer should be forbidden to entertain his listeners with singing as he himself will. Yet, even in this rigid environment of dogmas, some progress took place. Thus, in the 3rd century, Porphyry of Tyros graphically visualized the concept categories of Aristotle. In the 4thcentury of the Christian era, Pappus of Alexandria searched for a science of invention. He named his techniques â€Å"heuristics†. Antique Rome The Roman civilization developed from the Greek civilization. It was younger, thus more progressive and more exploratory than was the civilization of Greece. Therefore, things were seen in a different light in Rome, and the Greek concepts were viewed as partially outdated. To begin with, the vocabulary was enriched with new concepts, which shook up the foundations of the Greek thought. This effort happened to follow two counter-directions. on the one hand, Cicero wrote that art embraces those things â€Å"which are known† (â€Å"quae sciuntur†) [Tatarkiewicz, 1980, p. 245]. Horace, on the other hand, elevated painters to the level of poets in giving them the privilege of daring whatever they pleased (â€Å"quod libet audendi†), instead of following the â€Å"eternal model†. Moreover, in the declining period of antiquity, Lucius Flavius Philostratus discovered a similarity between poetry and art, and found that art and poetry have imagination in common. Cal listratos expanded these ideas by stating that as much as the art of the poets and writers of prosaic literature is inspired, so are the hands of sculptors. They, too, are gifted with the blessing of divine inspiration. The novelty of these postulates follows from the fact that Greeks had applied the concepts of imagination and inspiration to poetry only, but not to the visual arts. The Greek language had no word for creating, whereas Latin had. Creare and facere were two Latin words corresponding to the Greek à Ã¢â€š ¬ÃƒÅ½Ã‚ ¿ÃƒÅ½Ã‚ µÃƒÅ½Ã‚ ¹Ãƒ Ã¢â‚¬ ¦. Yet, initially the two Latin terms had almost the same meaning (Tatarkiewicz, 1980, p. 246), and were thus interchangeable. Christianity Under medieval Christianity, the Latin â€Å"creatio† came to designate Gods act of â€Å"creatio ex nihilo† (i.e. creation from nothing). â€Å"Creatio† thus no longer could apply to human activities. Its meaning differed from the meaning of â€Å"facere† (to make). Applied to human activities, facere was the only word to be used. Cassiodorus, the important statesman and writer of the 6th century, explained that things made and created differ, because we can make but cannot create. His important works on this topic, written after his retirement, include De anima (published 540), Institutiones Divinarum et Saecularium Litterarum (published probably 543-555), and De Artibus ac Disciplinis Liberalium Litterarum [Tatarkiewicz 1980, p. 247]. This more or less â€Å"secular† interpretation of creativity collided with the archaic views of some Christian writers. To begin with, they believed that art did not belong to the realm of creativity. In this respect they had the same belief as the Greeks. Medieval Christian writers granted no exception to poetry. They claimed that poetry had to follow its rules. Therefore it was an art, i. e. a craft rather than a creative activity. The dominant figure among these writers was St. Augustine, a personality whose works are of interest even today. He is claimed to have used the word imagination as a precursor to creativity. Imagination, according to St. Augustine comprised disposition, multiplication, reduction, extension, ordering, any kind of re-composition of images, etc. (Rodari, 1983). These very same components of â€Å"imagination† are used even today [Tatarkiewicz, 1980, p. 247]. Further changes were recorded in the Middle Ages: poetrys exceptional status was gradually revoked, because poetry had its rules. It was thus regarded as an art, i. e. a craft, rather than creativity. The new, religious interpretation of the expression notwithstanding, the opinion that art is not related to creativity persisted. The works of two influential early Christian writers, Pseudo-Dionysius and St. Augustine, prove it. The same can be said the works of Hraban the Moor and Robert Grosseteste, in the 13th century. Renaissance There are two periods in European history, called the Renaissance. The first one is the 12th century Renaissance. It was a period of many innovative and creative cahnges during the High Middle Ages, such as social, political and economic transformations. Parallel developments in philosophy and science resulted in an intellectual revitalization of Europe. The second renaissance is the Italian Renaissance in the 15th century. Some historians claim that the changes having taken place in the Middle Ages paved the way to the Italian Renaissance, as well as to the scientific developments of the 17th century. The French historian Jacques le Goff, an agnostic, argues that the Middle Ages formed an entirely new civilization, distinct from both the Greco-Roman antiquity, and from the modern world. The medieval achievements of the human mind and the human hands can only be related briefly. The First Rrenaissance . The most creative political acts of the 12th century were the founding of the Hansa in Northern Europe (along the southern shore of the North Sea and the Baltic Sea, with a few excursions deeper into Central Europe), the Crusades, the rise of towns, and the rise of the early bureaucratic states. In the cultural sphere the vernaculars began to replace Latin increasingly, higher education became more prominent, with universities sprouting all around the European continent between the Atlantic and the Theisse river, the Romanesque art was gradually replaced by the Gothic art, the liturgical drama, and a European system of law was established. These changes are true milestones. In the arts, more emphasis was put on architecture and sculpture, while in parallel there was a revival of interest in Latin poetry and Latin classics. An outer expansion began in the late 13th century, when the Venetian explorer Marco Polo set out to follow the Silk Road to China. His doc umentary Il Milone made Europeans more aware of the Far East, which inspired many missionaries (Giovanni da Pian del Carpini, Giovanni de Marignolli, Giovanni di Monte Corvino, and others) to go east and spread Christianity. The greatest leaps of human knowledge were, however, recorded in science and technology. Since Ibn al-Haytham (also known as Alhazen, 965-1039) laid down the foundations of the scientific method, the emphasis was put on seeking truth. Science thus became a formal discipline, different from philosophy. In early Middle Ages, the Byzantine Empire, the most advanced culture of antiquity, suffered losses and a decline in its scientific capacity. Likewise, Western Europe, after the fall of the Western Roman Empire, suffered a catastrophic loss of knowledge. This was partially offset by the efforts of Church scholars, like Aquinas and Buridan, who preserved elements of scientific inquiry. In that manner, by translating and imitating the works of Islamic scholars Europe could begin catching up with the scientific discoveries of the Islamic world, the Mediterranean basin, India, and China. The most important steps to Europes scientific recovery at that time comprise the following events: Development of the scientific method (Alhazen, Biruni, Bacon, and Grosseteste); Arithmetic and Algebra (Al-Khwarizmi); Differential calculus (Bhaskara); Mechanics (Avicenna, with a later contribution by Ibn Bajjah, also known as Avempace, Buridan, Galileo, Descartes and Newton); Optics(Aristotle, Plato, Galen, Euclid, Hero of Alexandria, Ptolemaeus. In the 10th century, Alhazen proved empirically that light propagates linearly;Robert Grosseteste developed a theory of optics based on the works of al-Kindi and Ptolemaeus. Roger Bacon expanded on Grossetestess theory and integrated Alhazens optics into it. Finally, Kepler was able to use the foregoing findings to develop the modern theory of optics); Surgery(Abulcasis or Abu al-Qasim Khalaf ibn al-Abbas Al-Zahrawi developed procedures and instruments of modern surgery, such as the scalpel, syringe, vaginal speculum, etc.). In 1266, Theodo ric Borgogni published his Chirurgia, in which he advocates antiseptic surgery); Alchemy and Chemistry (The Jaberian Corpus, written in the 10th century by the Brotherhood of Purity (Ismaylia), the Summa Perfectionis, by Paulus de Tarento, the Secret of Secrets by al-Razi (Abu Bakr Muhammad ibn Zakariya Razi);Trigonometry (al-Tusi, Regiomontanus and Puerbach made these methods wider known in the 15th century); Navigation (the astrolabe and the portable compass, Peter de Maricourt); Accurate lunar models(Ibn al-Shatir; Copernicus is believed to have relied on al-Shatirs model); Incendiary weapons and bombs (flame-throwers, land- and sea-mines, and rockets). Among important technological accomplishments and developments, the following can be listed: The windmill, first mentioned in 1185 (England); Paper manufacture began around 1270 (Italy); The spinning wheel (13th century); The magnetic compass for navigation, and the astrolabe (toward the end of the 13th century); Eyeglasses, in the late 13th century (Italy); The Hindu-Arabic numerals introduced to Europe in 1202 with the book Liber Abaci by Leonardo of Pisa; The stern-mounted rudder, which can be found on church carvings. The philosophy developed in the Middle Ages was the Scholasticism. It is founded on a reinterpretation of the works of Aristotle, with further refinements by scholars like Avicenna, Averroes, Albertus Magnus, Bonaventure, and Abà ©lard. Scholasticism believes in empirical studies, and its practitioners supported the Catholic Church. Perhaps the most famous practitioner of Scholasticism was Thomas of Aquinas. His Philosophy of mind teaches that the mind of a newborn baby is a tabula rasa that was given the ability to think, and to recognize forms, patterns, or ideas through a divine spark. In the late Middle Ages, the rate of scientific progress declined significantly due to the decline of the Muslim empires and the Byzantine Empire. This situation lasted until after the Renaissance. The Italian Reanaissance. The Italian Reanaissance brought further changes into the mode of thinking and lifestyle of people. The Renaissance philosophy is that of Humanism, which perhaps is more a method of learning than a philosophy per se. An approximate, but generally accepted definition of Humanism is â€Å"the movement to recover, interpret, and assimilate the language, literature, learning and values of ancient Greece and Rome†. Unlike the medieval scholars, humanists would apply a combination of reasoning and empirical evidence in reading and appraising ancient texts in the original. Humanist education focused on the study of five humanities: poetry, grammar, history, rhetoric, and moral philosophy. Above all, humanists asserted mans genius and the ability of the human mind, which is unique and extraordinary. Humanism is more secular in some aspects, but it unquestionably developed against a Christian backdrop, particularly in the Northern Renaissance. That period gave mankind some outstanding theologians, all of them followers of the humanist method. They include Zwingli, Calvin, Thomas More, Erasmus, and Martin Luther. In particular, Dr Martin Luther must be viewed as the liberator of the human soul, with whatever effect it had on subsequent cataclysmic developments in society, science, business, and trade. Although the people of the Renaissance were well aware of their freedom and creativity, the term creativity was not established yet. It was not until the 17th-century that the word â€Å"creativity† was applied for the first time. The man behind it was Polish poet Maciej Kazimierz Sarbiewski (1595-1640), also known as â€Å"the last Latin poet†. Sarbiewaski applied the term only to poetry. In his treatise, De perfecta poesi, he wrote that a poet â€Å"invents,† and creates anew (â€Å"de novo creat†) in the manner of God (â€Å"instar Dei†) (Tatarkiewicz, 1980, p. 248). Other arts, in Sarbiewskis opinion, do not create. They merely imitate and copy. Why Sarbiewski regarded creativity as something that only poetry could be associated with, thus excluding visual arts, follows from his opinion that arts (other than poetry) imitate and copy, rather than create, in that they assume the material from which they create is already available, and so is the subject. At the end of the 17th century Andrà © Fà ©libien (1619-75) called the painter â€Å"a creator†. Spanish Jesuit Baltasà ¡r Gracià ¡n (1601-58) saw art as the second Creator that complements nature. This formulation is reminiscent of Sarbiewskis formulations (Tatarkiewicz, 1980, p. 248). In the 18th century, the occurrence of the concept of creativity in art theory kept increasing. It was complemented with the concept of imagination. In Joseph Addisons opinion imagination â€Å"has something in it like creation†. A similar opinion was held by Voltaire (1740). These authors, however, equated only poet with creator (Tatarkiewicz, 1980, p. 248-9). Contrary views proliferated, too, particularly in France. Diderot worked with imagination, which he viewed merely as â€Å"the memory of forms and contents†, which â€Å"creates nothing†. It only combines, magnifies or diminishes. â€Å"The human mind cannot create†, wrote Charles Batteux. He, too, saw its products as displaying the stigmata of the model used. Étienne Bonnot de Condillac (1715-80) and Luc de Clapiers, known as marquis de Vauvenargues (1715-47), proposed similar ideas (Tatarkiewicz, 1980, p. 249). There were three reasons why they rejected the idea of human creativity: Creation was at that time reserved for creation ex nihilo. The latter was beyond mans abilities. Creation is a mysterious act. Enlightenment psychology, however, had no room for mysteries. Artists of that time age observed their rules. Creativity, however, seemed irreconcilable with rules. The third objection was, however, weak. Houdar de la Motte (1715) was one of the thinkers who suggested that rules, too, â€Å"are a human invention† (Tatarkiewicz, 1980, p. 249). The philosopher Marsilio Ficino wrote that the artists work is the result of thinking it up (â€Å"excogitatio†). Leon Battista Alberti, the theoretician of architecture and painting, claimed that he preordains (â€Å"preordinazione†), and Raphael claimed that his ideas shape his painting. Universal genius Leonardo da Vinci claimed that it was his idea that determined how his painting was shaped, using shapes that do not exist in nature. Another painter, Raphael Santi, too, claimed that he painted according to his ideas. Giorgio Vasari claimed that nature is conquered by art. Paolo Pino, the art theoretician from Venice claimed that painting is â€Å"inventing what is not†. Likewise, Paolo Veronese declared that painters take the same liberties as they were poets and madmen. â€Å"A new world, new paradises†was what an artist shapes, maintained Federico Zuccari. Cesare Cesariano extended this to architects whom he considered â€Å"demi-gods.† In the realm of music, according to the Dutch composer and musicologist Jan Tinctoris, a composer was â€Å"one who produces new songs†. He thus associated novelty with a composers work. Writers on poetry were even more consequent. Capriano claimed that poetic inventions spring â€Å"from nothing†. Francesco Patrizi held that poetry was a â€Å"fiction†, â€Å"shaping†, and â€Å"transformation† (Tatarkiewicz, 1980, p. 248). The developments in the Renaissance science were as dynamic as in the arts. Science and the arts were intermingled, which manifests best in the works of Leonardo da Vinci. He made observational drawings of nature and anatomy, set up and conducted controlled experiments in water-flow and aerodynamics, systematic study of motion, and medical dissection. Leonardo devised principles of scientific research method in the spirit of holistic, non-mechanistic and non-reductive approach popular today. Leonardo deserves the epithet â€Å"the father of modern science†. The focus on the process for discovery, the scientific method, corroborated by influential proponents such as Copernicus and Galileo, is perhaps the most significant development of that time. This revolutionary way of learning about the world stressed the importance of empirical evidence, as well as the importance of mathematics, rather than highlighting a given discovery. Age of Reason In the 18th century, the Age of Reason and Change, the concept of creativity appeared more frequently in art theory. Once again, famous personalities needed an ancillary concept to explain and justify creativity. One such concept was that of imagination. It was first used in 1712 by the English essayist, poet and publisher Joseph Addison. He published 11 essays on imagination in The Spectator. In one essay he claims that only the sense of sight supplies ideas to the imagination. He speculated about a congruence between imagiantion and creativity. By the same time, the famous French author and philosopher Franà §ois-Marie Arouet de Voltaire distinguished between passive and active imagination. On the latter he wrote in his Dictionnaire philosophique that â€Å"Active imagination is that which joins combination and reflection to memory. It brings near to us many objects at a distance; it separates those mixed together, compounds them, and changes them; it seems to create, while in fa ct it merely arranges; for it has not been given to man to make ideas-he is only able to modify them†. Voltaire continued: â€Å"This gift of nature is an imagination inventive in the arts in the disposition of a picture, in the structure of a poem.† Both authors thus indicate that poets are creative, and they equate poet with creator. Modern times The resistance against recognizing art as creativity, seen in the preceding centuries, crumbled totally in the 19thcentury. Now art gained recognition as creativity and, moreover, art alone was regarded as creativity. At the turn of the 20th century discussion of creativity in the art as well as in the sciences, e.g. by Jan Ã…Â ukasiewicz (Sinisi, 2004), and in nature (cf. Bergson, 1907) began. At this point concepts proper to art were applied to the sciences and to nature [Tatarkiewicz, 1980, p. 249]. There was, however, a long waiting time to the scientific study of creativity. The thinking of some modern time scholars will be expounded in the subsequent chapter. The beginning of scientific study of creativity is generally taken to be J. P. Guilfords address to the American Psychological Association in 1950. Many scholars joined in the effort to explore creativity in the years to come. They took a more pragmatic approach to this esoteric subject. As creativity became established as a discipline, scholars realized that creativity depends on being practiced. Creativity reveals itself in accomplishments and deeds, rather than in words. While a sound theoretical approach still was important, more and more emphasis was put on developing practical creativity techniques. Important personalities illustrating this approach include Alex Osborn, who in the 1950s invented brainstorming. In the same decade, Genrikh Altov, later calling himself Altshuller, came up with his â€Å"Theory of Inventive Problem Solving†, better known as TRIZ. In the 1960, Edward de Bono became famous after having developed his influential theory of â€Å"Lateral thinkin g.† These and other theories and techniques are expounded in more detail in subsequent chapters.
