Description

The title page to The Historians' History of the World

Historians write in the context of their own time, and with due regard to the current dominant ideas of how to interpret the past, and sometimes write to provide lessons for their own society. In the words of Benedetto Croce, "All history is contemporary history". History is facilitated by the formation of a 'true discourse of past' through the production of narrative and analysis of past events relating to the human race.^[13] The modern discipline of history is dedicated to the institutional production of this discourse.
All events that are remembered and preserved in some authentic form constitute the historical record.^[14] The task of historical discourse is to identify the sources which can most usefully contribute to the production of accurate accounts of past. Therefore, the constitution of the historian's archive is a result of circumscribing a more general archive by invalidating the usage of certain texts and documents (by falsifying their claims to represent the 'true past').
The study of history has sometimes been classified as part of the humanities and at other times as part of the social sciences.^[15] It can also be seen as a bridge between those two broad areas, incorporating methodologies from both. Some individual historians strongly support one or the other classification.^[16] In the 20th century, French historian Fernand Braudel revolutionized the study of history, by using such outside disciplines as economics, anthropology, and geography in the study of global history.
Traditionally, historians have recorded events of the past, either in writing or by passing on an oral tradition, and have attempted to answer historical questions through the study of written documents and oral accounts. For the beginning, historians have also used such sources as monuments, inscriptions, and pictures. In general, the sources of historical knowledge can be separated into three categories: what is written, what is said, and what is physically preserved, and historians often consult all three.^[17] But writing is the marker that separates history from what comes before.
Archaeology is a discipline that is especially helpful in dealing with buried sites and objects, which, once unearthed, contribute to the study of history. But archaeology rarely stands alone. It uses narrative sources to complement its discoveries. However, archaeology is constituted by a range of methodologies and approaches which are independent from history; that is to say, archaeology does not "fill the gaps" within textual sources. Indeed, Historical Archaeology is a specific branch of archaeology, often contrasting its conclusions against those of contemporary textual sources. For example, Mark Leone, the excavator and interpreter of historical Annapolis, Maryland, USA has sought to understand the contradiction between textual documents and the material record, demonstrating the possession of slaves and the inequalities of wealth apparent via the study of the total historical environment, despite the ideology of "liberty" inherent in written documents at this time.
There are varieties of ways in which history can be organized, including chronologically, culturally, territorially, and thematically. These divisions are not mutually exclusive, and significant overlaps are often present, as in "The International Women's Movement in an Age of Transition, 1830–1975." It is possible for historians to concern themselves with both the very specific and the very general, although the modern trend has been toward specialization. The area called Big History resists this specialization, and searches for universal patterns or trends. History has often been studied with some practical or theoretical aim, but also may be studied out of simple intellectual curiosity.^[18]

Etymology

History by Frederick Dielman (1896)

A derivation from *weid- "know" or "see" is attested as "the reconstructed etymon wid-tor ["one who knows"] (compare to English wit) a suffixed zero-grade form of the PIE root *weid- 'see' and so is related to Greek eidénai, to know".^[2][10]
Ancient Greek ἱστορία^[11] (hístōr) means "inquiry","knowledge from inquiry", or "judge". It was in that sense that Aristotle used the word in his Περὶ Τὰ Ζῷα Ἱστορίαι^[12] (Perì Tà Zôa Ηistoríai "Inquiries about Animals"). The ancestor word ἵστωρ is attested early on in Homeric Hymns, Heraclitus, the Athenian ephebes' oath, and in Boiotic inscriptions (in a legal sense, either "judge" or "witness", or similar).
The word entered the English language in 1390 with the meaning of "relation of incidents, story". In Middle English, the meaning was "story" in general. The restriction to the meaning "record of past events" arises in the late 15th century. It was still in the Greek sense that Francis Bacon used the term in the late 16th century, when he wrote about "Natural History". For him, historia was "the knowledge of objects determined by space and time", that sort of knowledge provided by memory (while science was provided by reason, and poetry was provided by fantasy).
In an expression of the linguistic synthetic vs. analytic/isolating dichotomy, English like Chinese (史 vs. 诌) now designates separate words for human history and storytelling in general. In modern German, French, and most Germanic and Romance languages, which are solidly synthetic and highly inflected, the same word is still used to mean both "history" and "story".
The adjective historical is attested from 1661, and historic from 1669.^[13]
Historian in the sense of a "researcher of history" is attested from 1531. In all European languages, the substantive "history" is still used to mean both "what happened with men", and "the scholarly study of the happened", the latter sense sometimes distinguished with a capital letter, "History", or the word historiography.^[12]

Historia
by Nikolaos Gysis (1892)

Those who cannot remember the past are condemned to repeat it.^[1]

—George Santayana

History (from Greek ἱστορία - historia, meaning "inquiry, knowledge acquired by investigation"^[2]) is an umbrella term that relates to past events as well as the discovery, collection, organization, and presentation of information about these events. The term includes cosmic, geologic, and organic history, but is often generically implied to mean human history. Scholars who write about history are called historians.
History can also refer to the academic discipline which uses a narrative to examine and analyse a sequence of past events, and objectively determine the patterns of cause and effect that determine them.^[3][4]
Historians sometimes debate the nature of history and its usefulness by discussing the study of the discipline as an end in itself and as a way of providing "perspective" on the problems of the present.^[3][5][6][7]
Stories common to a particular culture, but not supported by external sources (such as the tales surrounding King Arthur) are usually classified as cultural heritage or legends, because they do not support the "disinterested investigation" required of the discipline of history.^[8][9] Events occurring prior to written record are considered prehistory.
Herodotus, a 5th century B.C. Greek historian is considered to be the "father of history", and, along with his contemporary Thucydides, helped form the foundations for the modern study of human history. Their influence has helped spawn variant interpretations of the nature of history which have evolved over the centuries and continue to change today. The modern study of history is wide-ranging, and includes the study of specific regions and the study of certain topical or thematical elements of historical investigation. Often history is taught as part of primary and secondary education, and the academic study of history is a major discipline in University studies.

Principles of modern chemistry

Laboratory, Institute of Biochemistry, University of Cologne.

The current model of atomic structure is the quantum mechanical model.^[34] Traditional chemistry starts with the study of elementary particles, atoms, molecules,^[35] substances, metals, crystals and other aggregates of matter. This matter can be studied in solid, liquid, or gas states, in isolation or in combination. The interactions, reactions and transformations that are studied in chemistry are usually the result of interactions between atoms, leading to rearrangements of the chemical bonds which hold atoms together. Such behaviors are studied in a chemistry laboratory.
The chemistry laboratory stereotypically uses various forms of laboratory glassware, but glassware is not central to chemistry, and a great deal of experimental (as well as applied/industrial chemistry) is done without it.
A chemical reaction is a transformation of some substances into one or more different substances.^[36] The basis of such a chemical transformation is the rearrangement of electrons in the chemical bonds between atoms. It can be symbolically depicted through a chemical equation, which usually involves atoms as subjects. The number of atoms on the left and the right in the equation for a chemical transformation is equal (when unequal, the transformation by definition is not chemical, but rather a nuclear reaction or radioactive decay). The type of chemical reactions a substance may undergo and the energy changes that may accompany it are constrained by certain basic rules, known as chemical laws.
Energy and entropy considerations are invariably important in almost all chemical studies. Chemical substances are classified in terms of their structure, phase, as well as their chemical compositions. They can be analyzed using the tools of chemical analysis, e.g. spectroscopy and chromatography. Scientists engaged in chemical research are known as chemists.^[37] Most chemists specialize in one or more sub-disciplines. Several concepts are essential for the study of chemistry; some of them are:^[38]

History

The entrepreneur is a factor in microeconomics, and the study of entrepreneurship reaches back to the work of Richard Cantillon and Adam Smith in the late 17th and early 18th centuries, but was largely ignored theoretically until the late 19th and early 20th centuries and empirically until a profound resurgence in business and economics in the last 40 years.
In the 20th century, the understanding of entrepreneurship owes much to the work of economist Joseph Schumpeter in the 1930s and other Austrian economists such as Carl Menger, Ludwig von Mises and Friedrich von Hayek. In Schumpeter, an entrepreneur is a person who is willing and able to convert a new idea or invention into a successful innovation.^[5] Entrepreneurship employs what Schumpeter called "the gale of creative destruction" to replace in whole or in part inferior innovations across markets and industries, simultaneously creating new products including new business models. In this way, creative destruction is largely responsible for the dynamism of industries and long-run economic growth. The supposition that entrepreneurship leads to economic growth is an interpretation of the residual in endogenous growth theory and as such is hotly debated in academic economics. An alternate description posited by Israel Kirzner suggests that the majority of innovations may be much more incremental improvements such as the replacement of paper with plastic in the construction of a drinking straw.
For Schumpeter, entrepreneurship resulted in new industries but also in new combinations of currently existing inputs. Schumpeter's initial example of this was the combination of a steam engine and then current wagon making technologies to produce the horseless carriage. In this case the innovation, the car, was transformational but did not require the development of a new technology, merely the application of existing technologies in a novel manner. It did not immediately replace the horsedrawn carriage, but in time, incremental improvements which reduced the cost and improved the technology led to the complete practical replacement of beast drawn vehicles in modern transportation. Despite Schumpeter's early 20th-century contributions, traditional microeconomic theory did not formally consider the entrepreneur in its theoretical frameworks (instead assuming that resources would find each other through a price system). In this treatment the entrepreneur was an implied but unspecified actor, but it is consistent with the concept of the entrepreneur being the agent of x-efficiency.
Different scholars have described entrepreneurs as, among other things, bearing risk. For Schumpeter, the entrepreneur did not bear risk: the capitalist did.

Some notable persons and their works in entrepreneurship history.

For Frank H. Knight ^[6] (1921) and Peter Drucker (1970) entrepreneurship is about taking risk. The behavior of the entrepreneur reflects a kind of person willing to put his or her career and financial security on the line and take risks in the name of an idea, spending much time as well as capital on an uncertain venture. Knight classified three types of uncertainty.

• Risk, which is measurable statistically (such as the probability of drawing a red color ball from a jar containing 5 red balls and 5 white balls).
• Ambiguity, which is hard to measure statistically (such as the probability of drawing a red ball from a jar containing 5 red balls but with an unknown number of white balls).
• True Uncertainty or Knightian Uncertainty, which is impossible to estimate or predict statistically (such as the probability of drawing a red ball from a jar whose number of red balls is unknown as well as the number of other colored balls).

The acts of entrepreneurship are often associated with true uncertainty, particularly when it involves bringing something really novel to the world, whose market never exists. However, even if a market already exists, there is no guarantee that a market exists for a particular new player in the cola category.
The place of the disharmony-creating and idiosyncratic entrepreneur in traditional economic theory (which describes many efficiency-based ratios assuming uniform outputs) presents theoretic quandaries. William Baumol has added greatly to this area of economic theory and was recently honored for it at the 2006 annual meeting of the American Economic Association.^[7]
The entrepreneur is widely regarded as an integral player in the business culture of American life, and particularly as an engine for job creation and economic growth. Robert Sobel published The Entrepreneurs: Explorations Within the American Business Tradition in 1974. Zoltan Acs and David Audretsch have produced an edited volume surveying Entrepreneurship as an academic field of research,^[8] and more than a hundred scholars around the world track entrepreneurial activity, policy and social influences as part of the Global Entrepreneurship Monitor (GEM)^[9] and its associated reports.

Characteristics of an entrepreneur

This section does not cite any references or sources. (April 2009)

Entrepreneurs have many of the same character traits as leaders, similar to the early great man theories of leadership; however trait-based theories of entrepreneurship are increasingly being called into question. Entrepreneurs are often contrasted with managers and administrators who are said to be more methodical and less prone to risk-taking. Such person-centric models of entrepreneurship have shown to be of questionable validity, not least as many real-life entrepreneurs operate in teams rather than as single individuals. Still, a vast literature studying the entrepreneurial personality argues that certain traits seem to be associated with entrepreneurs:

• Bird - mercurial, that is, prone to insights, brainstorms, deceptions, ingeniousness and resourcefulness. they are cunning, opportunistic, creative, and unsentimental.
• Busenitz and Barney - prone to overconfidence and over generalizations.
• Cole - found there are four types of entrepreneur: the innovator, the calculating inventor, the over-optimistic promoter, and the organization builder. These types are not related to the personality but to the type of opportunity the entrepreneur faces.
• Collins and Moore - tough, pragmatic people driven by needs of independence and achievement. They seldom are willing to submit to authority.
• Cooper, Woo, & Dunkelberg - argue that entrepreneurs exhibit extreme optimism in their decision-making processes.
• John Howkins - focused specifically on creative entrepreneurship. He found that entrepreneurs in the creative industries needed a specific set of traits including the ability to prioritise ideas over data, to be nomadic and to learn endlessly. ^[10]
• David McClelland - primarily motivated by an overwhelming need for achievement and strong urge to build.

Qualities 1. Disciplined
These individuals are focused on making their businesses work, and eliminate any hindrances or distractions to their goals. They have overarching strategies and outline the tactics to accomplish them. Successful entrepreneurs are disciplined enough to take steps every day toward the achievement of their objectives.
2. Confidence
The entrepreneur does not ask questions about whether they can succeed or whether they are worthy of success. They are confident with the knowledge that they will make their businesses succeed. They exude that confidence in everything they do.
3. Open Minded
Entrepreneurs realize that every event and situation is a business opportunity. Ideas are constantly being generated about workflows and efficiency, people skills and potential new businesses. They have the ability to look at everything around them and focus it toward their goals.
4. Self Starter
Entrepreneurs know that if something needs to be done, they should start it themselves. They set the parameters and make sure that projects follow that path. They are proactive, not waiting for someone to give them permission.
5. Competitive
Many companies are formed because an entrepreneur knows that they can do a job better than another. They need to win at the sports they play and need to win at the businesses that they create. An entrepreneur will highlight their own company’s track record of success.
6. Creativity
One facet of creativity is being able to make connections between seemingly unrelated events or situations. Entrepreneurs often come up with solutions which are the synthesis of other items. They will repurpose products to market them to new industries.
7. Determination
Entrepreneurs are not thwarted by their defeats. They look at defeat as an opportunity for success. They are determined to make all of their endeavors succeed, so will try and try again until it does. Successful entrepreneurs do not believe that something cannot be done.
8. Strong people skills
The entrepreneur has strong communication skills to sell the product and motivate employees. Most successful entrepreneurs know how to motivate their employees so the business grows overall. They are very good at highlighting the benefits of any situation and coaching others to their success.
9. Strong work ethic
The successful entrepreneur will often be the first person to arrive at the office and the last one to leave. They will come in on their days off to make sure that an outcome meets their expectations. Their mind is constantly on their work, whether they are in or out of the workplace.
10. Passion
Passion is the most important trait of the successful entrepreneur. They genuinely love their work. They are willing to put in those extra hours to make the business succeed because there is a joy their business gives which goes beyond the money. The successful entrepreneur will always be reading and researching ways to make the business better.
Successful entrepreneurs want to see what the view is like at the top of the business mountain. Once they see it, they want to go further. They know how to talk to their employees, and their businesses soar as a result.

Entrepreneurship

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Entrepreneurship is the act and art of being an entrepreneur or "'one'who undertakes innovations or introducing new things, finance and business acumen in an effort to transform innovations into economic goods". This may result in new organizations or may be part of revitalizing mature organizations in response to a perceived opportunity. The most obvious form of entrepreneurship is that of starting new businesses (referred as Startup Company); however, in recent years, the term has been extended to include social and political forms of entrepreneurial activity. When entrepreneurship is describing activities within a firm or large organization it is referred to as intra-preneurship and may include corporate venturing, when large entities spin-off organizations.^[1]
According to Paul Reynolds, entrepreneurship scholar and creator of the Global Entrepreneurship Monitor, "by the time they reach their retirement years, half of all working men in the United States probably have a period of self-employment of one or more years; one in four may have engaged in self-employment for six or more years. Participating in a new business creation is a common activity among U.S. workers over the course of their careers." ^[2] And in recent years has been documented by scholars such as David Audretsch to be a major driver of economic growth in both the United States and Western Europe. "As well, entrepreneurship may be defined as the pursuit of opportunity without regard to resources currently controlled (Stevenson,1983)" ^[3]
Entrepreneurial activities are substantially different depending on the type of organization and creativity involved. Entrepreneurship ranges in scale from solo projects (even involving the entrepreneur only part-time) to major undertakings creating many job opportunities. Many "high value" entrepreneurial ventures seek venture capital or angel funding (seed money) in order to raise capital to build the business. Angel investors generally seek annualized returns of 20-30% and more, as well as extensive involvement in the business.^[4] Many kinds of organizations now exist to support would-be entrepreneurs including specialized government agencies, business incubators, science parks, and some NGOs. In more recent times, the term entrepreneurship has been extended to include elements not related necessarily to business formation activity such as conceptualizations of entrepreneurship as a specific mindset (see also entrepreneurial mindset) resulting in entrepreneurial initiatives e.g. in the form of social entrepreneurship, political entrepreneurship, or knowledge entrepreneurship have emerged.
