This paper investigates a well-known case of simultaneous discovery in twentieth-century chemistry, the origins of the concept of hybridisation, in the light of Kuhn's insights. There has been no ambiguity as to who discovered this concept, when it was "rst in print, and how important it was. The full-#edged form of the concept was published in 1931 independently by two American scientists John C. Slater (1900}1976) and Linus Pauling (1901}1994), although both of them had made their ideas public earlier: Slater (...) at the American Physical Society meetings in 1930, and Pauling in the Proceedings of the National Academy of Sciences in 1928. Slater and Pauling both argued for the necessity of using an s orbital as well as three p orbitals in the carbon atom in order to explain carbon's four valences and the tetrahedral structure of methane. The metaphor &hybridisation' for denoting this mix of s and p orbitals was "rst used by Robert S. Mulliken and J. H. Van Vleck before gaining currency with the scienti"c community around 1935.2 The concept of hybridisation was indeed indispensable for extending the quantum-mechanical interpretation of the chemical bond as an electron pairing from diatomic molecules to polyatomic ones. To be sure, the emergence of hybridisation attests to scientists' growing interest in exploring the borderland between physics and chemistry, a trend that led to the creation of physical chemistry in the late nineteenth century and of chemical physics and quantum chemistry in the 1920s and 30s. Slater and Pauling themselves experienced and on many occasions talked about the fruitfulness of interdisciplinary research; and historians have legitimately illuminated their works by examining them in this broad context.3 Yet the careful analysis of their research notes and published papers reveals that Slater and Pauling were working in quite disparate disciplinary traditions, with di!erent approaches, for di!erent audiences, and towards di!erent goals. The aim of this paper is to explore their di!erent routes to a common destination*hybridisation*and thereby to explicate tensions existing between physics and chemistry amidst the institutional and conceptual overlapping of the two disciplines.

As I had rejected en bloc references to Bacchanalia as indications of date, it was a mere chance which led me, after the above had left my hands, to look up Cas. 980 ‘ nunc Bacchae nullae ludunt,’ quoted in Schanz, R. Lit.3, p. 78. As this affords an excellent opportunity of testing my conclusions, perhaps a word or two will not be out of place.

Drawing from the Boulding''s (1956) framework for general systems theory, the need to employ richer paradigm in the study of organizations (Pondy and Mitroff, 1979) is reiterated. It is argued that a better understanding of organizational ethical behavior is contingent upon viewing organizations as symbol processing systems of shared language and meanings. Further, it is proposed that organizations, like individuals, develop into collectivities of shared cognitions and rationale, over a period of time. The study adapts Kohlberg''s (1983) model of moral (...) development to examine if organizations can be viewed as passing through different stages of moral development depending on the type of moral reasoning employed to explain their behaviors in the face of ethical crises. Several cases raising questions about the ethics of corporate behavior were researched. An instrument entitled Organization Response Analysis was constructed using statements made by various spokespersons representing five of these organizations. The instrument was administered to 246 graduate and undergraduate students of business (N = 246). Results indicated a great degree of concurrence among respondents of differing genders, levels of education and work experience in determining the stages of moral development of organizations. Limitations of the current study and implications for future research and practice are discussed. (shrink)

John Burdon Sanderson Haldane was a giant among men. He made major contributions to genetics, population biology, and evolutionary theory. He was at once comfortable in mathematics, chemistry, microbiology and animal physiology. But it was his belief in education that led to his preparing his popular essays for publication. In his own words: "Many scientific workers believe that they should confine their publications to learned journals. I think that the public has a right to know what is going on inside (...) the laboratories, for some of which it pays." So begins Haldane's collection of essays, perhaps the most public intellectual communicating science before the writings of Stephen Jay Gould. The first part of the volume emphasizes the important developments in biology and natural science in the first quarter of the century. As such, it provides a benchmark for studies of the next three quarters of the century. In an unusual introduction, Price takes the readers through their paces, discussing the situation then and now in vitamins, oxygen want, disease controls, and the rewards of science as such. This is followed by Haldane's views on society, art, religion and economy as seen through the eyes of a politically alert major scientist. The editor provides readers unfamiliar with Haldane with a carefully rendered chronology of a life that began in 1892 and that spanned much of the present century. Despite ideas on race, class and politics that have seen better times, Haldane was truly exceptional in translating the science of his time into ideas that "everyman" could readily grasp. His predictions on what science would achieve were on target far more often than not. But even his failed predictions are perhaps the most interesting of all. They throw into sharp relief the truly novel and revolutionary developments in science over the past 75 years. J.B.S. Haldane held many positions and received many honors during his lifetime. But for most of the period covered in this volume, he was the William Dunn Reader in Biochemistry at Cambridge University. He simultaneously served as Fellow of New College, in Oxford University's Horticultural Institute. Carl A. Price served until 1999 as professor IIof plant molecular biology in the Waksman Institute of Microbiology at Rutgers, the State University of New Jersey. He also served as the editor of Plant Molecular Biology Reporter from 1983 until 1997. This is the first volume in a new series on the history and theory of science. (shrink)

Medical confidentiality is a core concept of professionalism and should be an integral part of pregraduate and postgraduate medical education. The aim of our study was to define the factors influencing attitudes towards patient confidentiality in everyday situations in order to define the need for offering further education to various subgroups of physicians. All internists and general practitioners who were registered members of the association of physicians in Geneva or who were working in the department of internal medicine or in (...) the medical polyclinic of the University Hospital of Geneva in 2004 received a standardised questionnaire. Physicians were asked to indicate for seven vignettes whether a violation of confidentiality had occurred and whether the violation was not important, important or serious (scores 1–3; no violation = 0). 508 completed questionnaires were returned (participation rate 55%). Physicians who had worked in the hospital for more than 20 years identified violations of confidentiality more often than physicians with less hospital experience. Binary logistic regression showed that ethics education, total years of professional experience, being an internist, having a private practice, the length of working in private practice and gender were factors associated with correct identification of violations and their severity. However, each factor played a specific role only for single cases or a small number of situations (Cronbach α <0.6). Postgraduate education programs on confidentiality should be offered to a wide range of physicians and should address specific hypothetical situations in which there is a risk of avoidable breaches of confidentiality.

Objectives: To compare attitudes of medical and law students toward informing a cancer patient about diagnosis and prognosis and to examine whether differences are related to different convictions about benefit or harm of information.Setting and design: Anonymous questionnaires were distributed to convenience samples of students at the University of Geneva containing four vignettes describing a cancer patient who wishes, or alternatively, who does not wish to be told the truth.Participants: One hundred and twenty seven medical students and 168 law students.Main (...) outcome measures: Five point Likert scale of responses to the vignettes ranging from “certainly inform” to “certainly not inform” the patient.Results: All medical students and 96% of law students favoured information about the diagnosis of cancer if the patient requests it. Seventy four per cent of medical students and 82% of law students favoured informing a cancer patient about his or her prognosis . Thirty five per cent of law students and 11.7% of medical students favoured telling about the diagnosis and 25.6% of law students and 7% of medical students favoured telling about the prognosis even if the patient had clearly expressed his wish not to be informed. Law students indicated significantly more often than medical students reasons to do with the patient’s good, legal obligations, and the physician’s obligation to tell the truth, and significantly less often than medical students that their attitude had been determined predominantly by respect for the autonomous choice of the patient.Conclusion: Differences in attitudes according to the type of case and the type of studies were related to convictions about the benefit or harm to the patient caused by being given information. The self reported reasons of future physicians and future lawyers are helpful when considering means to achieve a better acceptance of patients’ right to know and not to know. (shrink)

In International Law and World Order, B. S. Chimni articulates an integrated Marxist approach to international law combining the insights of Marxism, socialist feminism and postcolonial theory. The book uses IMAIL to systematically and critically examine the most influential contemporary theories of international law including new, feminist, realist and policy-oriented approaches. In doing so, it discusses a range of themes relating to the history, structure and process of international law. The book also considers crucial world order issues and problems that (...) the international legal process has to contend with, including the welfare of weak groups and nations, the ecological crisis and the role of human rights. This extensively revised second edition provides an invaluable, in-depth and updated review of the key literature and scholarship within this field of study. It will be of particular interest to students and scholars of international law, international relations, international politics and global studies. (shrink)

Due to the COVID-19 Pandemic, several changes have been forcibly made and observed in various fields and areas of society, one of which include the field of education; the foundation of the formation of intellect and knowledge. After two years of studying indoors and private educational institutions holding virtual classes, the time has finally come for students to be re- adjusted once more to the blended mode of learning; a combination of virtual and in-person classes. Thus, this study aimed to (...) investigate the development of students’ study habits and how these habits could potentially affect the students’ academic achievement or performance. The study utilized a descriptivecorrelational design to examine the impact of study habits to the academic performance of 137 senior high school students. The study made use of the Palsane and Sharma’s Study Habits Inventory, or also known as PSSHI, and using this instrument, the study has been able to procure sufficient results that will answer the present study’s problems. Using linear regression analysis, the present study found that there was a significance between the study habits and academic performance of the senior high school students, thus the study’s null hypothesis was eventually rejected.

Formal definitions of the following concepts of animal ecology are given: environment, niche, locality, local population, natural population, community, ecosystem. Five primitive (undefined) notions are used including "animal", "offspring" and "habitat", the latter in the sense of Charles Elton. The defining equations for the environment of one animal are first given, then niche (in the Elton sense) is formally defined in terms of the environment. The fifth primitve notion "habitat" is then introduced in order to define the remaining concepts.

The spatial organization of the genome is intimately linked to its biological function, yet our understanding of higher order genomic structure is coarse, fragmented and incomplete. In the nucleus of eukaryotic cells, interphase chromosomes occupy distinct.

In his account of probable reasoning, Poincaré used the concept, or at least the language, of conventions. In particular, he claimed that the prior probabilities essential for inverse probable reasoning are determined conventionally. This paper investigates, in the light of Poincaré's well known claim about the conventionality of metric geometry, what this could mean, and how it is related to other views about the determination of prior probabilities. Particular attention is paid to the similarities and differences between Poincaré's conventionalism as (...) it applies to probabilities and de Finetti's subjectivism. The aim of the paper is to suggest that in accounts of the development of ideas about probable reasoning, particularly those customarily described as Bayesian, Poincaré's discussion deserves more attention than it has so far received.
