Evolutionary explanations of pain expression require modeling social adaptations in a context where the role of health professionals as potential caregivers, conflicts with their status as relative strangers. As signals of help elicitation or of alarm, facial pain displays and responses to displays, particularly in the upper face, are expected to conform to this evolutionarily novel clinical context.

Notable in cross-cultural comparisons is the variable span of time between when children become economically self-sufficient and when they initiate their own reproductive careers. That variation is of interest because it shapes the age range of children reliant on others for support and the age range of children available to help out, which in turn affects the competing demands on parents to support multiple dependents of different ages. The age at positive net production is used as a proxy to estimate (...) the close of juvenile economic dependence among a group of Maya subsistence agriculturalists. Maya children produce more than they consume by their early to mid teens but remain in their natal households for a number of years before leaving home and beginning families of their own. The Maya results contrast markedly with those from several groups of hunter-gatherers and horticulturalists for whom we have similar data. Even in the Maya case, where children are self-sufficient at a relatively young age, parents are unable to support their children without help from others. The production surplus of older children appears to help underwrite the cost of large Maya families and subsidize their parents’ continued reproduction. (shrink)

To date, research into socially responsible investment (SRI), and in particular the socially responsible investment funds industry, has focused on whether investing in SRI assets has any differential impact on investor returns. Prior findings generally suggest that, on a risk-adjusted basis, there is no difference in performance between SRI and conventional funds. This result has led to questions about whether SRI funds are really any different from conventional funds. This paper examines whether the portfolio allocation across industry sectors and the (...) stock-picking ability of SRI managers are different when compared to conventional fund managers. The study finds that SRI funds exhibit different industry betas consistent with different portfolio positions, but that these differences vary from year to year. It is also found that there is little difference in stock-picking ability between the two groups of fund managers. (shrink)

This collection brings together fourteen contributions by authors from around the globe. Each of the contributions engages with questions about how local and global bioethical issues are made to be comparable, in the hope of redressing basic needs and demands for justice. These works demonstrate the significant conceptual contributions that can be made through feminists' attention to debates in a range of interrelated fields, especially as they formulate appropriate responses to developments in medical technology, global economics, population shifts, and poverty.

The evolution of cooperative breeding is complex, and particularly so in humans because many other life history traits likely evolved at the same time. While cooperative childrearing is often presumed ancient, the transition from maternal self-reliance to dependence on allocare leaves no known empirical record. In this paper, an exploratory model is developed that incorporates probable evolutionary changes in birth intervals, juvenile dependence, and dispersal age to predict under what life history conditions mothers are unable to raise children without adult (...) cooperation. The model’s outcome variable (net balance) integrates dependent children’s production and consumption as a function of varying life history parameters to estimate the investment mothers or others have to spend subsidizing children. Results suggest that maternal-juvenile cooperation can support the early transition toward a reduction in birth intervals, a longer period of juvenile dependence, and having overlapping young. The need for adult cooperation is most evident when birth intervals are short and age at net production is late. Findings suggest that the needs of juveniles would not have been an early selective force for adult cooperation. Rather, an age-graded division of labor and the mutual benefits of maternal-juvenile cooperation could be an important, but overlooked step in the evolution of cooperative breeding. (shrink)

Research in nonindustrial small-scale societies challenges the common perception that human childhood is universally characterized by a long period of intensive adult investment and dedicated instruction. Using return rate and time allocation data for the Savanna Pumé, a group of South American hunter-gatherers, age patterns in how children learn to become productive foragers and from whom they learn are observed across the transition from childhood to adolescence. Results show that Savanna Pumé children care for their siblings, are important economic contributors, (...) learn by doing rather than by instruction, and spend their time principally in the company of other children. This developmental experience contrasts with that of children in postindustrial societies, who are dependent on adults, often well past maturity; learn in formal settings; and spend much of their time in the company of adults. These differences raise questions about whether normative behaviors observed in postindustrial societies are representative of human children. This comparison also identifies the potential mismatch between hunter-gatherer and postindustrial societies in the extent to which children may be well adapted to learn from and teach each other. In particular, spending time in autonomous work and play groups develops the cooperation and coordination skills that are foundational to human subsistence and growing up to be socially and productively adept adults and parents.

Attention has been given to cross-cultural differences in adolescent growth, but far less is known about developmental variability during juvenility (ages 3–10). Previous research among the Pumé, a group of South American foragers, found that girls achieve a greater proportion of their adult stature during juvenility compared with normative growth expectations. To explain rapid juvenile growth, in this paper we consider girls’ activity levels and energy expended in subsistence effort. Results show that Pumé girls spend far less time in subsistence (...) tasks in proportion to their body size compared with adults, and they have lower physical activity levels compared with many juveniles cross-culturally. Low activity levels help to explain where the extra energy comes from to support rapid growth in a challenging environment. We suggest that activity levels are important to account for the variation of resource and labor transfers in mediating energy availability. (shrink)

Dispersal of individuals from their natal communities at sexual maturity is an important determinant of kin association. In this paper we compare postmarital residence patterns among Pumé foragers of Venezuela to investigate the prevalence of sex-biased vs. bilateral residence. This study complements cross-cultural overviews by examining postmarital kin association in relation to individual, longitudinal data on residence within a forager society. Based on cultural norms, the Pumé have been characterized as matrilocal. Analysis of Pumé marriages over a 25-year period finds (...) a predominant pattern of natalocal residence. We emphasize that natalocality, bilocality, and multilocality accomplish similar ends in maximizing bilateral kin affiliations in contrast to sex-biased residential patterns. Bilateral kin association may be especially important in foraging economies where subsistence activities change throughout the year and large kin networks permit greater potential flexibility in residential mobility.

This study argues that there is a moral dimension to sensational news. The study assumes that citizens have a moral interest in the community because moral standards play a role in governing social behavior. Some news, labeled as sensational, reflects news of the moral life of the community and is related to the community's moral well-being. This study addresses the problem of making the distinction between such news and news that is sensational for its own sake. This study also suggests (...) a method that journalists can use to responsibly cover stories traditionally associated with press sensationalism. (shrink)

Using qualitative data based on interviews with 22 married infertile couples living in western New York State, we describe the ways in which husbands and wives interact in the process of constructing their infertility. The wives experienced infertility as a cataclysmic role failure. Husbands tended to see infertility as a disconcerting event but not as a tragedy. Couples tended to see infertility as a problem for wives. Frustration and lack of communication were typical consequences of the confrontation of husbands' and (...) wives' perspectives on infertility. Interactions with medical professionals tended to reinforce these consequences. These interactions between wives, husbands, and medical professionals may lead to taking wrong directions in treatment and to ignoring treatment options. Some of the problems we describe could be lessened by adopting a model of couple-centered treatment in a setting that incorporated routine counseling. (shrink)

Children’s literature was first published in the eighteenth century at a time when the philosophical ideas of Jean-Jacques Rousseau on education and childhood were being discussed. Ironically, however, the first generation of children’s literature (by Maria Edgeworth et al) was incongruous with Rousseau’s ideas since the works were didactic, constraining and demanded passive acceptance from their readers. This instigated a deficit or reductionist model to represent childhood and children’s literature as simple and uncomplicated and led to children’s literature being overlooked (...) and its contribution to philosophical discussions being undermined. Although Rousseau advocates freeing the child to develop, he does not feel that reading fiction promotes child development, which is a weakness in an otherwise strong argument for educational reform. Yet, rather ironically, the second generation of children’s writers, from Lewis Carroll onwards, more truly embraced Rousseau’s broader philosophical ideas on education and childhood than their predecessors, encouraging and freeing readers to imagine, reflect and actively engage in ontological enquiry. The emphasis had changed with the child being embraced in education and society as active participant rather than passive or disengaged recipient. Works deemed to be seminal to the canon of children’s literature such as Alice’s Adventures in Wonderland, Peter Pan and The Chronicles of Narnia challenge readers to work through conflicts many of which can be identified retrospectively as exhibiting postmodern characteristics. By exploring moral and spiritual dilemmas in their writing, Carroll, Barrie and Lewis’s works can be regarded as contributing to discussions on theodical postmodernism. The successes of The Lord of the Rings and Narnia films suggest that there is an interest in exploring moral dilemmas, fulfilling a need (perhaps for tolerance and understanding) in society at large. Children’s literature has an almost divine power to restore, to repair and to heal, all characteristics of theodical postmodernism but differing from the more widely held conception of postmodernism which pulls apart, exacerbates and exposes. Children’s literature therefore offers a healthy and constructive approach to working through moral dilemmas. In their deconstruction of childhood, these authors have brought children’s literature closer to aspects of enquiry traditionally found in the domain of adult mainstream literature. As the boundaries between childhood and adulthood become more fluid, less certain, debate is centring around whether the canon of children’s literature itself has become redundant or meaningless since there are no longer any restrictions on which subjects can be treated in children’s literature. Despite the fact that children’s literature clearly engages with difficult issues, it continues to be left out of the critical equation, not given serious attention, disregarded as simplistic and ignored in contemporary philosophical discussions concerning morality, postmodernism and the future of childhood. With children’s literature coming closer to mainstream literature, and exhibiting prominent features of postmodernism, however, it is only a matter of time before philosophical discussions actively engage with children’s literature and recognise its contribution to the resolution and reconciliation of ontological dilemmas. When this occurs, philosophy and children’s literature will re-engage, enriching contemporary investigations of existence, ethics and knowledge and fruitfully developing thought in these areas. This paper aims to contribute to this process. (shrink)

First published in 1980, this book questions many of the assumptions that have accumulated around the subject of intonation as it occurs in spontaneous speech, as well as texts read aloud. The book suggests alternative ways of examining the subject and primarily uses data derived from Edinburgh speech, which is explicitly compared with descriptions of standard southern English.The book critically examines many conventional assumptions made about the formal features of intonation, particularly 'tonic' or primary stress', and about the functions of (...) intonation, specifically rising intonation. A model of intonation is presented which demonstrates that the limited resources of intonation are exploited by several different expressive systems. This approach is justified in detailed analysis of extensive stretches of speech, supported by instrumental analysis as well as by experiments which elicit judgements by both naïve and phonetically trained judges.

This article is a commentary response to the study results outlined in “The State of Teacher Training in Philosophy.” In recognition of the study’s determination that 70 percent of the jobs new philosophers will apply for are non-tenure track, our graduate programs must provide training in teaching excellence and the fostering of student learning, or what I call pedagogical areté. I will argue that achieving this teaching excellence requires 1) Familiarity with cognitive neuroscience advancements on how people learn, 2) Knowledge (...) of today’s college students, and 3) Practiced methods for scaffolding and assessment of student learning. My claim is that pedagogic excellence is both a role-related moral obligation and a duty we owe to society—what Lee Shulman characterizes as the pedagogical imperative. This increased focus on pedagogical proficiency creates an opportunity for philosophy to establish and solidify its disciplinary value. (shrink)

In the mid 1970s labor-saving technology was introduced into a Maya subsistence agricultural community that markedly increased the efficiency with which maize could be ground and water collected. This increased efficiency introduces a possible savings in the time that women allocate to work, which can be reapportioned to child care, food production, domestic work, or leisure. An earlier study suggested that this labor-saving technology had a positive effect in decreasing the age at which these Maya women begin their reproductive careers. (...) Although there is a statistical association between the age at which women bear their first child and the introduction of modern technology, this association does not demonstrate that the decline in age at first birth is causally related to the presence of technology. This paper pursues two objectives to evaluate this potential causal relationship in greater detail. First, a theory relating technological change to the initiation of a reproductive career is briefly developed in order to make qualitative predictions about behavioral changes as a response to changing technology. Second, these predictions are then tested against time allocation data recently collected in this same Maya community.We suggest that both of the conditions necessary to initiate reproduction—fecundity and access to mates—fundamentally depend on the amount of help that a girl provides to her family. Further, the help that a girl provides can be affected by technological changes. Analyses show that when modern technology is available, unmarried young women do not change the time allocated to domestic tasks and child care, and allocate more time to low-energy leisure activities. This lack of perceived benefit to working more and a potential concomitant shift towards a positive energy balance may in part explain why Maya women leave home and initiate reproduction at a younger age after labor-saving technology is introduced.

The question of why helpers help is debated in the cooperative breeding literature. Recent reevaluations of inclusive fitness theory have important implications for traditional populations in which the provisioning of young occurs in the context of intergenerational transfers. These transfers link older and younger generations in an economic relationship that both minimizes the demand for help and the cost of helping.
