Taking Isaac Newton at his own word, historians have long agreed that the decade of the 1660s, when Newton was a young man in his twenties, was the critical period in his scientific career. In the years 1665 and 1666, he has told us, he hit on the ideas of cosmic gravitation, the composition of white light, and the fluxional calculus. The elaboration of these basic ideas constituted his scientific achievement. Nevertheless, the decade of the 1660s has remained a virtual (...) blank in our knowledge of Newton. It need not remain so always. His papers contain a wealth of manuscripts from his undergraduate years and the period immediately following. The first volume of his mathematical papers, which will soon be published, will demonstrate how extensive the information on his early mathematical development is. The development of his non-mathematical studies, especially of what I shall call his scientific studies to distinguish them from the mathematical, can be followed as well—in his reading notes, in his notebooks, above all in the passage in his philosophical notebook labelled Quaestiones quaedam Philosophicae. In this passage we see emerging into consciousness for the first time the questions on which Newton's philosophy of nature was built. (shrink)

This study examines the effect of a business ethics course on undergraduates’ attitudes toward the importance of corporate ethics and social responsibility, as measured by the PRESOR scale. It employs a survey approach, adopting a pretest/posttest methodology in the data collection. A total of 132 undergraduate students were surveyed over a period of four semesters during 2006 and 2007. To test the effects of individual personality characteristics and examine their potential interaction with ethical education, participants’ personal values and degree of (...) Machiavellianism were also assessed. The business ethics course resulted in significantly less support for the traditional “stockholder view” of business, providing backing for the inclusion of a stand-alone business ethics course in the business studies curriculum. In addition, among nonbusiness majors, the course resulted in significantly greater support for the “stakeholder view,” suggesting that it would be especially beneficial to open such a course to nonbusiness students.

Knowledge and expertise -- Knowledge and action -- The nature of professional action in urban planning.

Isaac Newton was indisputably one of the greatest scientists in history. His achievements in mathematics and physics marked the culmination of the movement that brought modern science into being. Richard Westfall's biography captures in engaging detail both his private life and scientific career, presenting a complex picture of Newton the man, and as scientist, philosopher, theologian, alchemist, public figure, President of the Royal Society, and Warden of the Royal Mint. An abridged version of his magisterial study Never at Rest, (...) this concise biography makes Westfall's highly acclaimed portrait of Newton newly accessible to general readers. (shrink)

From the very day in 1686 when Edmond Halley placed Book I of the Principia before the Royal Society, Robert Hooke's claim to prior discovery has been associated with the law of universal gravitation. If the seventeenth century rejected Hooke's claim summarily, historians of science have not forgotten it, and a steady stream of articles continues the discussion. In our own day particularly, when some of the glitter has worn off, not from the scientific achievement, but from the character of (...) Newton, there has been a tendency vicariously to atone for the treatment Hooke received. The judgement Lohne cites with approval from Vavilov appears to summarize the current estimate of the issue—in the seventeenth century only Newton could have written the Principia; nevertheless Hooke first sketched out its programme. What with all the knocks he has received both alive and dead, one feels guilty in assuming the role of “debunker” at this late date. Apologetically draped in sackcloth then, head covered with ashes I venture softly to suggest that Hooke has received more than his due. There is no question here of justifying Newton's behaviour toward Hooke. Wholly lacking in generosity as it appears to me, Newton's behaviour neither deserves nor can receive justification. The question turns rather on Hooke's scientific theories. Granting always his lack of demonstrations, historians have been prone to interpret his words in the light of Newton's demonstrations. A close examination of Hooke's writings does not sustain the interpretation. Contrary to what is generally asserted, he did not hold a conception of universal gravitation. And if he announced the inverse square relation, he derived it from such a medley of confusion as will not allow his claim to priority. (shrink)

Almost exactly ten years ago, the now extinct U.S. Congress, Office of Technology Assessment (OTA) released a major report -- The Electronic Supervisor: New Technology, New Tensions. This report describes a number of new technologies available to management in its ongoing search to ensure that labour performs its required job to management's rigid specifications. Social issues raised with respect to electronic monitoring included privacy, fairness, quality of working life, and stress-related illnesses. The study was also concerned with drug testing, genetic (...) screening, polygraph testing, as well as a variety of technologies for eavesdropping and monitoring. It seems to be appropriate to evaluate the analyses and recommendations made in the report and to extend the evaluation to current technologies. (shrink)

How transcription factors achieve their in vivo specificities is a fundamental question in biology. For the Homeotic Complex (HOM/Hox) family of homeoproteins, specificity in vivo is likely to be in part determined by subtle differences in the DNA binding properties inherent in these proteins. Some of these differences in DNA binding are due to sequence differences in the N‐terminal arms of HOM/Hox homeodomains. Evidence also exists to suggest that cofactors can modify HOM/Hox function by cooperative DNA binding interactions. The Drosophila (...) homeoprotein extradenticle (exd) is likely to be one such cofactor. In HOM/Hox proteins, both the conserved ‘YPWM’ peptide motif and the homeodomain are important for interacting with exd. Although exd provides part of the answer as to how specificity is achieved, there may be additional cofactors and mechanisms that have yet to be identified. (shrink)

In El Salvador from 1978 to 1988, contraceptive use among married women 15–44 years of age increased from 34% to 47%, and the total fertility rate declined from 6·3 to 4·6 children per woman. Most of this change took place from 1978 to 1985. Sterilization is the most prevalent method used, but nearly one-half of the women who are sterilized did not use any contraception before their operation. Few young couples use reversible methods of contraception to space births or delay (...) the start of childbearing. On average, women wait 8 years after marriage and have nearly three children before they use contraception. (shrink)

Although researchers have begun to examine how firms manage their entire web of stakeholder relationships, the component relationships also require theoretical and empirical examination. Several studies have found that Employee Stock Ownership Plans (ESOPs) have a positive impact on firm performance. The authors explain these results by hypothesizing that ESOPs, when combined with employee participation programs, forge a stakeholder relationship between management and employees. The authors offer criteria for identifying stakeholder relationships, provide background on ESOPs, analyze why they contribute to (...) establishing such a relationship, and examine how published empirical research supports this analysis. The authors conclude by suggesting directions for future research. (shrink)

Every constitution defines and is defined by a period in time. Like all law the creation and application of constitutions require reference to the past and future respectively. Every instance of constitution‐making is an attempt to control behavior over an extended period of time. Therefore constitutions will be drafted, both in style and substance, to reflect that temporal ambition. The effectiveness of a constitution also requires that its interpretation makes reference to the understanding of its rules held by the constitution‐makers. (...) As a result, and notwithstanding the efforts to make it suitable over a long period by its creators, every constitution is bound to become unsuitable. Courts employ a number of devices to cope with the inevitable obsolescence of constitutions but, sooner or later, every constitution will have to be discarded and a new constitutional era begun.

Safety testing of biological pharmaceuticals is often carried out by contract testing laboratories which perform these tests on behalf of the drug’s developer. These laboratories are confronted with a number of ethical issues related to selling their services, maintaining confidentiality, and the handling of results. This paper outlines these issues, and, by way of illustration, discusses how one such laboratory addresses them.

Drafting a code of ethics for a professional society is a daunting and exhausting task. Whereas the basic components of a professional code of ethics or professional standards are reasonably well understood, the specific details require careful tailoring to meet the needs of a given profession. The difficulty of this process probably explains why such codes are rarely updated. Furthermore, once having produced an updated ethics code, many professional organizations, or perhaps better the associated executive, feel that their work has (...) been completed and that they can now present themselves to their countries and the international community as responsible and even concerned societies. But is their work really over? The answer proposed in this paper is a resounding no. I argue that a professional society must provide active and comprehensive support to its members as they seek to do the right thing. In this regard, the Web pages of the ACM and the IEEE are compared as evidence of each society's commitment to its members. I also argue that professional societies must make this commitment and as importantly, be seen to be making it. (shrink)
