Coalitions and alliances are core aspects of human behavior. All societies recognize alliances among communities, usually based in part on kinship and marriage. Aggression between groups is ubiquitous, often deadly, fueled by revenge, and can have devastating effects on general human welfare. Given its significance, it is surprising how little we know about the neurobiological and hormonal mechanisms that underpin human coalitionary behavior. Here we first briefly review a model of human coalitionary behavior based on a process of runaway social (...) selection. We then present several exploratory analyses of neuroendocrine responses to coalitionary social events in a rural Dominican community, with the objective of understanding differences between in-group and out-group competition in adult and adolescent males. Our analyses indicate: (1) adult and adolescent males do not elevate testosterone when they defeat their friends, but they do elevate testosterone when they defeat outsiders; (2) pre-competition testosterone and cortisol levels are negatively associated with strength of coalitionary ties; and (3) adult males usually elevate testosterone when interacting with adult women who are potential mates, but in a striking reversal, they have lower testosterone if the woman is a conjugal partner of a close friend. These naturalistic studies hint that reciprocity, dampening of aggression, and competition among friends and allies may be biologically embedded in unique ways among humans. (shrink)

Lottery puzzles involve an ordinary piece of knowledge which seems to imply knowledge of a so-called “lottery proposition,” which itself seems unknown: I might be said to know that I won’t be going on safari next year. But if I were to win the lottery, I would go, and I don’t know that I won’t win the lottery. Examples can be multiplied. Thus we seem left either with the paradoxical position of knowing certain ordinary propositions, but failing to know the (...) lottery propositions they imply, or else conceding to the skeptic. I present a version of reliabilism according to which empirical knowledge is true belief produced by a reliable process causally connecting belief and fact. According to this theory, if my ordinary belief and my belief in the lottery proposition are suitably connected to the facts that render them true, both count as knowledge. In cases where my ordinary belief and my belief in the lottery proposition are not suitably connected to the relevant facts, neither count as knowledge. Thus the paradoxical air of lottery puzzles is removed, and skepticism is avoided. (shrink)

This study examines the family environments and hormone profiles of 316 individuals aged 2 months-58 years residing in a rural village on the east coast of Dominica, a former British colony in the West Indies. Fieldwork was conducted over an eight-year period (1988–1995). Research methods and techniques include radioimmunoassay of cortisol and testosterone from saliva samples (N=22,340), residence histories, behavioral observations of family interactions, extensive ethnographic interview and participant observation, psychological questionnaires, and medical examinations.Analyses of data indicate complex, sex-specific effects (...) of family environment on endocrine function. Male endocrine profiles exhibit greater sensitivity to presence of father than do female endocrine profiles. Father-absent males tend to have (a) low cortisol levels during infancy, (b) high or abnormal cortisol profiles during childhood and adolescence, and (c) high cortisol and low testosterone levels during adulthood compared with those of males raised with a resident father. These results indicate that early family environment has significant effects on endocrine response throughout male life histories. (shrink)

With contributions from leading scholars in constitutional law, this volume examines how carefully designed and limited doctrines of proportionality can improve judicial decision-making, how it is applied in different jurisdictions, its role on constitutionalism outside the courts, and whether the principle of proportionality actually advances or detracts from democracy. Contributions from some of the seminal thinkers on the development of scholarship on proportionality extend their prior work and engage in an important dialogue on the topic. Some offer substantial critiques, others (...) defend the doctrine and offer important clarifications and extensions of their prior work. Throughout, the authors engage not only with case law from around the world but also with existing scholarly treatments of the subject. Mathematical treatments are avoided, making the book accessible to readers from both 'soft' and hard' social science backgrounds. (shrink)

An extended period of childhood and juvenility is a distinctive aspect of human life history. This stage appears to be important for learning cultural, social, and ecological skills that help prepare the child for the adult socio-competitive environment. The unusual pattern of adrenarche in humans (and chimpanzees) may facilitate adaptive modification of the neurobiological mechanisms that underpin reproductive strategies. Longitudinal monitoring of DHEA/S in naturalistic context could provide important new insights into these aspects of child development.

Despite a consensus across the political spectrum that the problem of the chronically uninsured is in dire need of solution, little progress has been made. Public spending goes to topping up coverage for the elderly, already heavily subsidized under Medicare, or helping people temporarily without insurance because of international trade dislocations, so that it is clear that something is lacking in the case for significantly reducing the number of uninsured persons. In this paper I suggest that there have been two (...) missing ingredients: a strategy for breaking the political deadlock around this issue, and information about the benefits of coverage sufficient to persuade kindly but skeptical taxpayers that they should be willing to pay to help solve this problem.

Employers must determine the types of health care plans to offer and also set employee premiums for each plan provided. Depending on the structure of the employee share of premiums across different health insurance plans, the incentives to choose one plan over another are altered. If employees know premiums do not fully reflect the risk differences among workers, such pricing can give rise to a so-called “death spiral” due to adverse selection. This paper uses longitudinal information from a natural experiment (...) in the management of health benefits for a large employer to explore the impact of moving from a fixed-dollar contribution policy to a partially risk-adjusted employer contribution policy. Our results show that implementing a significant risk adjustment had no discernable effect on adverse selection against the most generous indemnity insurance policy. This stands in stark contrast to previous studies, which have tended to estimate large impacts attributed to selection when employers move to a fixed-dollar policy from one with some risk adjustment. Further analysis suggests that previous studies, which appeared to detect plans in the throes of a death spiral, may instead have been reflecting an inexorable movement away from a non-preferred product, one that would have been inefficient for nearly all workers even in the absence of adverse selection.

The recent Supreme Court decision on several provisions of the Patient Protection and Affordable Care Act provides an opportunity to address two kinds of design flaws in the legislation whose correction would both improve economic efficiency and some important dimensions of equity. The Court's view that the mandate is a tax is consistent with the general economic view that defines a tax as “a compulsory payment for public purposes.” This was the viewpoint I took in my earlier work as well. (...) However, there is considerable difference, disagreement, and ambiguity about the public purpose sought by the ACA payment. The primary purpose of the mandate in my work and in arguments for the mandate in Massachusetts was to try to get as many people as possible to have at least some insurance coverage. A secondary consequence of a mandate is to shore up community rating, although community rating per se does not contribute (and generally is harmful) to the goal of covering a greater proportion of the population.

To achieve lower medical spending with as little reduction as possible in good outcomes, practitioners and policy makers alike have been experimenting with the use of practice guidelines. These guidelines both recommend certain types of therapies and proscribe others in the treatment of patients with particular conditions. This paper explores the question of whether guidelines which do reduce total resource costs of medical care to a population will be feasible and produce “acceptable” results. The definition of acceptable is part of (...) the policy problem, so it will be left open for a while, but the question of which outcomes match with which levels of resource cost will form the positive basis for the normative judgment of “acceptability.”.

An excellent introduction to the field of international relations, The Global Philosophers examines the intellectual roots of contemporary literature on international relations and discusses the historical context in which famous historical political theorists wrote.

It has been apparent for at least a decade that liberal constitutional theory is in deep trouble. Of course there are many versions of liberal constitutional theory, but they have essentially no connection to existing practices of constitutional law, considering as practices of constitutional law all the activities of our institutions of government that implicate - interpret, advance, deal with, whatever - fundamental principle. Instead, liberal constitutional theory's vision of the future is nostalgia for the past. For liberal constitutional theorists (...) the Warren Court, or Justice Brennan, basically got everything right, at least in their approach to identifying constitutional law. True, they may have faltered sometimes in implementing constitutional principles, but all that needs to be done today is to appoint justices in the mold of Warren, Brennan, or Thurgood Marshall. And here I really do mean all that needs to be done: No rethinking of what constitutional law is all about seems needed to liberal constitutional theorists. (shrink)

The post-Civil War American natural history craze spawned a new institution -- the natural history dealer -- that has failed to receive the historical attention it deserves. The individuals who created these enterprises simultaneously helped to promote and hoped to profit from the burgeoning interest in both scientific and popular specimen collecting. At a time when other employment and educational prospects in natural history were severely limited, hundreds of dealers across the nation provided encouragement, specimens, publication outlets, training opportunities, and (...) jobs for naturalists of all motivations and levels of expertise. This paper explores the crucial role that specimen dealers played in the larger natural history community. After briefly examining the development of local taxidermy shops in the mid-nineteenth century, it then traces the history of four large natural history dealerships established in the United States during the latter half of the century: Ward's Natural History Establishment, Frank Blake Webster's Naturalists' Supply Depot, Southwick & Jencks' Natural History Store, and Frank H. Lattin & Co. By the early twentieth century, changing tastes in interior design, the growth of the Audubon movement, and the dramatic expansion of alternate training and job opportunities for naturalists led many specimen dealers either to shift their emphasis or to shut their doors.

Patterns of human kinship commonly involve preferential treatment of relatives based on lineal descent (lineages) rather than degree of genetic relatedness (kindreds), presenting a challenge for inclusive fitness theory. Here, we examine effects of lineage and kindred characteristics on reproductive success (RS) and number of grandchildren for 130 men and 124 women in a horticultural community on Dominica. Kindreds had little effect on fitness independently of lineage characteristics. Fitness increased with the number of lineal relatives residing in the community but (...) decreased beyond an apparently optimal lineage size, suggesting resource enhancement and competition among kin. Female-biased patrilineage sex ratio was positively associated with men’s fitness, while male-biased matrilineage sex ratio was positively associated with women’s fitness. Number of brothers in the community was negatively associated with men’s, but not women’s, fitness. Parents and number of sisters had no effect on either male or female reproduction; however, women with younger sisters had higher RS, suggesting benefits of kin support for childcare. In sum, imposed norms for lineage social organization may enhance lineal ancestors’ inclusive fitness at a cost to individual inclusive fitness. (shrink)

There is an ongoing debate over the ethical status of policies that give an employer the right to discharge an employee without a good reason or notice (i.e., employment at-will policies). This article moves beyond the question of whether the adoption of such a policy is unethical per se under all circumstances, focusing instead on the following question: Assuming that an at-will policy is not unethical per se in all circumstances, what are the ethical issues associated with an employer's implementation (...) and maintenance of an employment at-will policy, and how can these issues be addressed? Three primary ethical concerns are identified and discussed, and specific propositions regarding employers' obligations are presented. The article concludes by offering practical guidance intended to assist at-will employers in meeting the identified ethical obligations. (shrink)

Research providing consistent evidence of pervasive discrimination against overweight job applicants and employees in the American workplace raises important questions for organizational stakeholders. To what extent is the disparate treatment of job applicants or employees based on their weight ethically justified? Are there aspects of weight discrimination that make it more acceptable than discrimination based on other characteristics, such as race or gender? What operational steps can employers take to address concerns regarding the ethical treatment of overweight individuals in the (...) workplace? This article investigates these and related questions. Its purpose is to provide information and analysis that will assist organizations in formulating ethical responses to a widespread phenomenon: weight discrimination in the workplace. Although its focus is the American workplace, the proposed employer ethical obligations and the practical guidance that is provided are viewed as generalizing across countries and cultures. (shrink)
