"This is the book that I have been waiting for for twenty years. With exceptional clarity, Draine introduces the underlying physics and brings the basic pieces together to describe the multiphase structure of the interstellar and intergalactic medium. Combined with many useful tables and figures, this book will rapidly become a hit with students and researchers alike. It continues the fine tradition of Princeton professors writing seminal books on this topic."--Ewine van Dishoeck, Leiden University "A true tour de force, providing (...) a definitive account of the physics of interstellar matter. Written with authority and insight by a master of the subject, Bruce Draine's book will be a treasured guide for new graduate students as well as a comprehensive and rigorous reference for galactic and extragalactic researchers."--Eve Ostriker, University of Maryland "Draine has written an interstellar-medium textbook worthy of Lyman Spitzer, updated thirty years later. His coverage of atomic, molecular, radiative, thermal, and dynamical processes is excellent. Most valuable to students and professionals are the combinations of physical processes with multiwavelength observations appropriate for the modern astronomer."--J. Michael Shull, University of Colorado at Boulder "This book is a comprehensive account of the physical processes that take place in the interstellar medium and that determine its behavior. It is likely to become the bible on the subject."--Alexander Dalgarno, Harvard University "This is an outstanding text on an important topic in astrophysics. Draine carefully goes into the physical processes, providing a unifying discussion that is often missing in other treatments."--Christopher F. McKee, University of California, Berkeley. (shrink)

ABSTRACT Alchemy is part of the cultural experience of early modern Europe and yet has had to overcome problems of demarcation to be considered relevant to the history of science. This essay considers historiographical and methodological issues that have affected the gradual demarginalization of alchemy among attempts to explain, and find things out about, nature. As an area of historical study, alchemy relates to the history of science as part of an ensemble of practices that explored the natural world through (...) natural philosophy and speculative traditions and by functioning as a nexus of social and intellectual life.

The neural transplantation research described by Sinden and colleagues provides part of the rationale for the clinical application of neural transplantation. The authors are asked to clarify their view of the role of the cholinergic system in cognition, to address extrahippocampal damage caused by transient forebrain ischemia, and to consider the effects of delayed neural degeneration in their structure-function analysis.

It has become increasingly evident that gene content of the sex chromosomes is markedly different from that of the autosomes. Both sex chromosomes appear enriched for genes related to sexual differentiation and reproduction; but curiously, the human X chromosome also seems to bear a preponderance of genes linked to brain and muscle functions. In this review, we will synthesize several evolutionary theories that may account for this nonrandom assortment of genes on the sex chromosomes, including 1) asexual degeneration, 2) sexual (...) antagonism, 3) constant selection, and 4) hemizygous exposure. Additionally, we will speculate on how the evolution of sex‐chromosome gene content might have impacted on the phenotypic evolution of mammals and particularly humans. Our discussion will focus on the mammalian sex chromosomes, but will cross reference other species where appropriate. BioEssays 26:159–169, 2004. © 2004 Wiley Periodicals, Inc. (shrink)

Literature addressing organizational ethical behavior has focused intensely on cognitive moral development, and more recently the automatic and natural moral inclinations. Research addressing the incapacity for moral reasoning, such as psychopathy, is rarely addressed in organizational behavior. Our first aim is to develop a construct definition for functional psychopathy that is appropriate for organizational science and theoretically consistent with the extensive previous clinical and criminal research in this field. Second, we apply two versions of a scale not previously used in (...) business research relative to moral judgments. This scale is a self-reported measure of functional psychopathy and is useful for its relationships with ethically relevant business decisions. Further, we examine which factors emerge as having the highest relationship with ethical decision making. Third, we seek to advance the usefulness of this construct by more precisely placing psychopathy within its nomological network. With these goals in mind, a combined sample of business school seniors participated in three studies. Findings indicate a significant influence of psychopathy over a range of ethically relevant business decisions, as well as negative correlations with factors of the Moral Approbation and the Moral Awareness scales. We conclude with directions for future research and considerations for practice. (shrink)

The objective of this paper is to augment the business values literature by building upon research that claims individual value frames are subject to hierarchical re-scaling, value redefinition, and value removal or induction. In contrast to the person-organization cultural fit approach of value congruence, we postulate that the cognitive discomforts resulting from just-world needs, self-identity completion and self-concept maintenance, as moderated by contextual and dispositional variables, are resolved through the selection and accentuation of legitimating and justifying values that ultimately cast (...) the nature of the world as fair, complete central self-identities, and affirm the self. Research and practical implications are discussed. (shrink)

Members of organizations are continually making decisions that have important consequences for themselves and the firms for which they work. In some cases these decisions affect human well being and social welfare and thus have important ethical impacts for those affected by the decisions.This study examines if certain strategic situations (enhancement of firm profits versus personal economic well being) cause decision makers to act more or less ethically. A questionnaire consisting of two vignettes which depicted actual business situations was used (...) to collect data from 171 managers of a large Southeastern financial and communication conglomerate. Results from multivariate repeated measures tests suggest that managers will vary their level of ethical response when faced with a situation where their own economic well being is at stake.

A new study entitled “Normal gut microbiota modulates brain development and behavior”, published in the Proceedings of the National Academy of Sciences, requires that we reconsider the notion that the brain is an immune‐privileged site. The authors demonstrate that intestinal microbiota must be present within a set time‐frame for normal synaptogenesis to occur in the brain. In the absence of intestinal microbiota, histopathological and behavioral abnormalities arise. These observations necessitate a new look at the many interconnections of the immune system (...) and the brain, suggesting new frontiers for research and new therapeutic strategies for neurodevelopmental diseases.

In this paper our aim is to augment the value-congruency literature by demonstrating the dynamics of business value structures. The relationship between cognitive discomforts and value restructuring is examined by applying self-affirmation theory. Subjects (N = 115) were randomly assigned either to the treatment group (n = 69) or control group (n = 46). Those subjects in the treatment group were tasked with deciding between two different organizational re-structuring options that involved downsizing. The values of job-entitlement, and obligations to the (...) disadvantaged shifted in emphasis in a direction that legitimated and justified the lay-off decision. The value of economic nationalism remained unchanged. Implications for research and practice are discussed. (shrink)

ABSTRACT:Organizations constitute morally-complex environments, requiring organization members to possess levels of moral courage sufficient to promote their ethical action, while refraining from unethical actions when faced with temptations or pressures. Using a sample drawn from a military context, we explored the antecedents and consequences of moral courage. Results from this four-month field study demonstrated that authentic leadership was positively related to followers’ displays of moral courage. Further, followers’ moral courage fully mediated the effects of authentic leadership on followers’ ethical and (...) pro-social behaviors. Theoretical and practical implications for further integrating the work on moral courage, authentic leadership and ethics are discussed. (shrink)

Ockham realized the value of a careful study and application of the mathematical theory of continuity, even though he possessed no conclusive empirical evidence that it adequately explained the continuity experienced in the world of sense. He also clearly perceived a relation of continuity to infinity, since continuity, as a property of an order which is possible only to a series of terms, must have an infinite number of terms. “A continuous series must have an infinite number of terms.”.
