Nearly Supersymmetric Dark Atoms

Theories of dark matter that support bound states are an intriguing possibility for the identity of the missing mass of the Universe. This article proposes a class of models of supersymmetric composite dark matter where the interactions with the Standard Model communicate supersymmetry breaking to the dark sector. In these models supersymmetry breaking can be treated as a perturbation on the spectrum of bound states. Using a general formalism, the spectrum with leading supersymmetry effects is computed without specifying the details of the binding dynamics. The interactions of the composite states with the Standard Model are computed and several benchmark models are described. General features of non-relativistic supersymmetric bound states are emphasized.Comment: 39 pages, 2 figure

Co-wife Conflict and Cooperation

Conventional wisdom holds that the polygynous family system is as sexually and emotionally satisfying as a monogamous one. Ethnographic accounts of 69 polygynous systems, however, provide compelling evidence that the majority of co-wives in a polygynous family prefer pragmatic co-operation with one another while maintaining a respectful distance. Moreover, there often is a deep-seated feeling of angst that arises over competing for access to their mutual husband. Co-wife conflict in the early years of marriage is pervasive, and often marked by outbursts of verbal or physical violence. Co-wife conflict may be mitigated by social institutions, such as sororal polygyny and some form of social security or health care. Material wealth may be divided more or less equally, but as a husband\u27s sexual attention (a primary source for increased fertility) and affection cannot always be equitably distributed, there is ongoing and contentious rivalry among co-wives.

Gender, Sexual Orientation, and Truth-of-Consensus in Studies of Physical Attractiveness

Truth-of-consensus methodology presently holds that sex differences in perceptions of physical attractiveness are negligible and may be routinely ignored during prescaling. No determination has been made in the literature of the effects of sexual orientation on this perceptual process. The data presented herein suggest that while sex and sexual orientation of judge are largely irrelevant to prescaling of female stimuli, these variables are important when judging male stimuli. In particular, male homosexuals and male heterosexuals differ significantly in ranking male facial photographs. Thus, experimenters wishing to treat attractiveness levels as known quantities should control for this difference, especially when using a small number of judges for prescaling

In the Name of the Father: Theology, Kinship and Charisma in an American Polygamous Community

Following periods of intense debate and eventual demise, kinship studies is now seeing a revival in anthropology. New Directions in Anthropological Kinshipcaptures these recent trends and explores new avenues of inquiry in this re-emerging subfield. The book comprises contributions from primatology, evolutionary anthropology, archaeology, and cultural anthropology. The authors review the history of kinship in anthropology and its theory, and recent research in relation to new directions of anthropological study. Moving beyond the contentious debates of the past, the book covers feminist anthropology on kinship, the expansion of kinship into the areas of new reproductive technologies, recent kinship constructions in EuroAmerican societies, and the role of kinship in state politics

Father-Child Relations in Urban China

Due to a greater involvement of American fathers in the direct care of their children in recent years, interest in the impact and nature of the father’s role in nurturing children has increased. While studies about fathers in the industrialized, literate West have proliferated, little is known about the role of fathers in the preliterate, non-Western world. This collection examines the diversity of paternal roles found in human cultures among various types of societies that are very peaceful and those that actively engage in warfare as a mode of existence. Father-Child Relations recognizes the importance of understanding both biological and cultural aspects of the father’s role. Many of the contributors utilize evolutionary or biosocial models, including those of developmental psychology, to examine the father’s role, while others rely upon the symbolic analysis of cultural and social anthropology. One chapter is devoted to male-infant relationships in nonhuman primates, a further largely ignored comparative perspective. The anthropologists who have contributed to this collection are field workers who have lived intimately over significant periods of time with the people about whom they are writing. These research reports from the field have been edited to make them wholly accessible to the non-specialist. The contributors of this volume recognize that biology and ideology are intertwined; both together influence the father’s behavior and the effects of his behavior

From Courtship to Dating Culture: China’s Emergent Youth

This compelling book explores the explosive pace of change in China and how its citizens are grappling with a dramatically new world, both in the public and private spheres. China s stratospheric growth has made it the second largest economy in the world and one of the most unequal. Marxist ideology and socialist ideals have almost completely collapsed, replaced by a combination of materialism and assertive nationalism. The vast migration of labor from countryside to city has continued apace. The pressures of a hypercompetitive market economy are ripping apart the traditional family and threatening the environment. Corruption has reached new heights. The political system is even more rigid, but perhaps more brittle, than a decade ago. There is enormous popular pride in the ascension of China to the rank of global superpower and general satisfaction in the material benefits that the poor as well as the rich have been gaining from an expanding economy. But there is also great restlessness, anger about structural injustice and political corruption, and a search for new forms of spirituality and ethics to replace a collapsing moral order. The question What does it mean, in the new day, to be Chinese? lurks just beneath the surface. This unique interdisciplinary book frames this central issue through an innovative set of case studies on such cutting-edge topics as reality dating shows, countercultural invented language, star bloggers, faith healers, and subversive jokes.
