Although risky decision-making has been posited to contribute to the maladaptive behavior of individuals with psychopathic tendencies, the performance of psychopathic groups on a common task of risky decision-making, the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994), has been equivocal. Different aspects of psychopathy (personality traits, antisocial deviance) and/or moderating variables may help to explain these inconsistent findings. In a sample of college students (N = 129, age 18–27), we examined the relationship between primary and secondary psychopathic (...) features and IGT performance. A measure of impulsivity was included to investigate its potential as a moderator. In a joint model including main effects and interactions between primary psychopathy, secondary psychopathy and impulsivity, only secondary psychopathy was significantly related to risky IGT performance, and this effect was not moderated by the other variables. This finding supports the growing literature suggesting that secondary psychopathy is a better predictor of decision-making problems than the primary psychopathic personality traits of lack of empathy and remorselessness.

The main object of this impressive study is to lay the groundwork, in contemporary terms, for a systematic and philosophically respectable "apology for poetry." The author finds that most of the so-called New Critics agree in rejecting both the "sugar-coated pill" and "l'art pour l'art" views of poetry; their efforts to formulate a workable third view form the basis for his elaboration of the requirements of an acceptable theory, one which will accord with--and do justice to--the unique and irreducible (...) aesthetic experience to which poetry gives rise. The details of such a theory, unfortunately, are never made entirely clear, owing in part to the diverse and often conflicting demands which must be met, but its main points are as follows: poems, though mainly self-contained, their meanings determined contextually rather than referentially, yet "reveal life," "illuminate human experience"; in poetic creation, though the poet's intentions somehow control the outcome, yet the language of the evolving poem itself determines its own final nature; and poetry, though it neither merely instructs or informs nor merely pleases, yet does provide a kind of "truth" and does produce an experience in some sense pleasurable. The strength of Mr. Krieger's study lies in the clarity and force with which he states the various issues, and in the scholarly care with which he examines the views of individual critics. The book, however, lacks tight organization and sustained, clearly directed argumentation, and its final outcome is rather inconclusive.--V. C. C. (shrink)

Scientists exhibit different styles in their reasoning about the natural world (e.g., experimental, historical, or statistical). These styles have been characterized, categorized, and combined in many ways throughout the history of science.

The author takes anderson to task for resting his argument on an "appeal to english usage," without analyzing that usage in relation to his point that subjunctive and counterfactual conditionals belong in one class. (staff).

Over 300 years ago the father of microscopy, Antonie van Leeuwenhoek, observed dried rotifers “coming back to life” upon rehydration. Since then, scientists have been fascinated by the enduring mystery of how certain organisms survive losing essentially drying out completely. Historically sugars, such as the disaccharide trehalose, have been viewed as major functional mediators of desiccation tolerance. However, some desiccation tolerant organisms do not produce this sugar, hinting that additional mediators, and potentially novel mechanisms exist. It has become apparent (...) that a common theme among such organisms is the production and use of intrinsically disordered proteins to mediate survival in this dry state. However, the basic biology of these proteins – which unlike globular proteins lack persistent three-dimensional structure – is poorly understood, as are the functional mechanisms utilized by these enigmatic proteins that allow them to mediate desiccation tolerance. We purpose that probing the biochemical and biophysical nature of stress-related IDPs will provide mechanistic insights into these fascinating proteins. Remarkably, organisms from every kingdom of life can survive losing nearly all their intracellular water. A hallmark of desiccation tolerance is the use of intrinsically disordered proteins, but how IDPs contribute to tolerance is poorly understood. Here, we discuss possible mechanisms and avenues for studying these enigmatic proteins. (shrink)

Many things have passed as money: salt in Abyssinia, tea-bricks in Asia, sugar in the West Indies, barrels of oil in Texas … and metals everywhere. The list seems endless. However, as transactions increased, wealth accumulated, and states levied taxes, such proto-moneys moved from the simple “double coincidence of wants” into more rational and complex forms. They catered for a market or hierarchy of markets. “Money,” said Carl Menger, “is not a political invention.”.
