We report here on recent developments in Israel on the issue of sex selection for nonmedical reasons by preimplantation genetic diagnosis. Sex selection for medical reasons is generally viewed as uncontroversial and legal in European and American law. Its use for nonmedical reasons is generally illegal in European countries. In the United States, it is not illegal, although in the opinion of the Ethics Committee of the American Society for Reproductive Medicine, it is problematic. This position is undergoing reconsideration, albeit (...) in a limited way. (shrink)

Benjamin Franklin exhorted his fellows to “either write something worth reading or do something worth writing.” John Stuart Mill is among that rare breed who managed to do both. He was a public intellectual before the term was created; an advocate for a humanist, self‐reflective life, but also a man of political action. Mill's thought and life do not stand apart from each other. He was in fact an intensely autobiographical thinker. Mill's extraordinary upbringing and education, for example, fuelled his (...) journey away from utilitarianism towards liberalism. His deep relationship with Harriet Taylor also strongly influenced his thinking on gender equality, social custom and other issues. Mill's life is interesting in itself. It also casts an important light on the development of his thought. (shrink)

Recently the terms “codes” and “information” as used in the context of molecular biology have been the subject of much discussion. Here I propose that a variety of structural realism can assist us in rethinking the concepts of DNA codes and information apart from semantic criteria. Using the genetic code as a theoretical backdrop, a necessary distinction is made between codes qua symbolic representations and information qua structure that accords with data. Structural attractors are also shown to be entailed by (...) the mapping relation that any DNA code is a part of (as the domain). In this framework, these attractors are higher-order informational structures that obviate any “DNA-centric” reductionism. In addition to the implications that are discussed, this approach validates the array of coding systems now recognized in molecular biology. (shrink)

These six articles place conflicts in Asia within the context of peace psychology, catalogues the diversity of conflicts in Asia, describes the inspiring success Philippine citizens have had in effecting drastic change in political leadership through nonviolent protest, and examines stereotypes in Sino-Japanese relations. Research on two extremist groups in Pakistan-one endorsing and one not endorsing violent confrontation is then examined. The concluding article contributes to the argument that Asia can provide novel examples of conflict that broaden our perspective.

This issue is the first in a projected series of issues devoted to the contributions of pioneers in the field of peace psychology, starting with _Peace and Conflict_ Founding Editor, Milton Schwebel. This inaugural issue presents not only portions of the interview with Schwebel, but a brief resumé and representative publications for each decade, 1940-2000. It continues with statements from three of his colleagues providing accounts of his importance to them. Then, a paper dealing with the moral development of child (...) soldiers in conflict throughout the world is discussed. Finally, Schwebel's recent book is the subject of a Review Essay. (shrink)

Because little is known about the human trait of affiliation, we provide a novel neurobehavioral model of affiliative bonding. Discussion is organized around processes of reward and memory formation that occur during approach and consummatory phases of affiliation. Appetitive and consummatory reward processes are mediated independently by the activity of the ventral tegmental area (VTA) dopamine (DA)–nucleus accumbens shell (NAS) pathway and the central corticolimbic projections of the u-opiate system of the medial basal arcuate nucleus, respectively, although these two projection (...) systems functionally interact across time. We next explicate the manner in which DA and glutamate interact in both the VTA and NAS to form incentive-encoded contextual memory ensembles that are predictive of reward derived from affiliative objects. Affiliative stimuli, in particular, are incorporated within contextual ensembles predictive of affiliative reward via: (a) the binding of affiliative stimuli in the rostral circuit of the medial extended amygdala and subsequent transmission to the NAS shell; (b) affiliative stimulus-induced opiate potentiation of DA processes in the VTA and NAS; and (c) permissive or facilitatory effects of gonadal steroids, oxytocin (in interaction with DA), and vasopressin on (i) sensory, perceptual, and attentional processing of affiliative stimuli and (ii) formation of social memories. Among these various processes, we propose that the capacity to experience affiliative reward via opiate functioning has a disproportionate weight in determining individual differences in affiliation. We delineate sources of these individual differences, and provide the first human data that support an association between opiate functioning and variation in trait affiliation. Key Words: affiliation corticolimbic-striatal networks; appetitive and consummatory reward; dopamine; oxytocin; personality; social bonds; social memory; u-opiates. (shrink)
