Non‐invasive microanalytical methods have been devised to study the energy metabolism of single human preimplantation embryos. Psyruvate, which is added routinely to all media used to culture human embryos, is consumed throughout the preimplantation period, with glucose assuming an increasing role at embryo compaction and blastocyst formation. All of the glucose consumed may be accounted for by the appearance of lactate in the incubation medium. The enzyme hexokinase my be involved in regulating this aerobic glycolysis. There is cosiderable indirect evidence (...) for the utilisation of endogenous as opposed to exogenous energy substrates, the most likely candidate being protein. Information on early human embryo metabolismis likely to find application in a number of areas: these include the improvement of techniques for assisted human conception, notably in the selection of embryos for transfer following In Vitro Fertilisation; the diagnosis of gentic defects at the preimplantation stage; increased undersding of the causes of implantation failure and miscarriage, and the development of novel post‐coital contraceptives.

The primary purpose of this study was to examine the effects of perceptions of product harm and consumer vulnerability on ethical evaluations of target marketing strategies. We first established whether subjects are able to accurately judge the harmfulness of a product through labeling alone, and whether they could differentiate consumers who were more or less vulnerable. The results suggest that without the presence of a prime, subjects who depended on implicit memory or guess were able to detect differences in “sin” (...) and “non-sin” products and consumer vulnerability, but were far less likely to be able to distinguish among high and low levels of product harm and consumer vulnerability. The inability to accurately identify high and low levels of product harm and consumer vulnerability impacted their perceptions of the ethicality of target marketing strategies, such that only four out of 18 target marketing strategies were judged as unethical. Thus, our findings contradict previous research that found subjects judged many more of the integrated strategies as unethical [Smith and Cooper- Martin, J Market 61 1]. Our results suggest that assessing ethical evaluations of strategies varying in product harm, and consumer vulnerability may only be relevant if consumers can accurately identify product harm.

Background To determine whether fetal care paediatric and maternal–fetal medicine specialists harbour differing attitudes about pregnancy termination for congenital fetal conditions, their perceived responsibilities to pregnant women and fetuses, and the fetus as a patient and whether self-perceived primary responsibilities to fetuses and women and views about the fetus as a patient are associated with attitudes about clinical care.Methods Mail survey of 434 MFM and FCP specialists .Results MFMs were more likely than FCPs to disagree with these statements : ‘the (...) presence of a fetal abnormality is not an appropriate reason for a couple to consider pregnancy termination’ ; ‘the effects that a child born with disabilities might have on marital and family relationships is not an appropriate reason for a couple to consider pregnancy termination’ ; and ‘the cost of healthcare for the future child is not an appropriate reason for a couple to consider pregnancy termination’ . 65% MFMs versus 47% FCPs disagreed that their professional responsibility is to focus primarily on fetal well-being . Specialists did not differ regarding the fetus as a separate patient. Responses about self-perceived responsibility to focus on fetal well-being were associated with clinical practice attitudes.Conclusions Independent of demographic and sociopolitical characteristics, FCPs and MFMs possess divergent ethical sensitivities regarding pregnancy termination, pregnant women and fetuses, which may influence clinical care.

Grounded in a close reading of the records of Joan's trial and rehabilitation, on the early letters announcing her arrival at Chinon, and on three literary works; Christine de Pizan's Ditié, Martin le Franc's Le Champion des dames, and Alain Chartier's, Traité de l’Esperance, this controversial work argues that serious historians should accept that Joan was trained. It proposes that she was identified and taught how to behave in the expectation of the fulfillment of the Charlemagne Prophecy and other (...) prophecies from the Joachite tradition. It explores the possibility that Christine de Pizan, who had been promoting these prophecies from the beginning of the century, had some hand in the process that resulted in Joan's appearance and demonstrates, at the very least, that there are many links connecting Christine de Pizan to the knights who fought with Joan.

This essay considers and rejects both the irrationalist and the supra-rationalist interpretations of Kierkegaard, arguing that a new category---Kierkegaard as “anti-rationalist”---is needed. The irrationalist reading overemphasizes the subjectivism of Kierkegaard’s thought, while the suprarationalist reading underemphasizes the degree of tension between human reason (as corrupted by the will’s desire to be autonomous and self-sustaining) and Christian faith. An anti-rationalist reading, I argue, is both faithful to Kierkegaard’s metaphysical and alethiological realism, on the one hand, and his emphasis on the continuing (...) opposition between reason and faith, on the other, as manifested in the ongoing possibility of offense (reason’s rejection of the Christian message) in the life of the Christian.

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.

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)

To make possible the integration proposed by Domjan et al., psychologists first need to close the research gap between behavioral ecology and the study of Pavlovian conditioning. I suggest two strategies, namely, to adopt more behavioral ecological approaches to social behavior or to co-opt problems already addressed by behavioral ecologists that are especially well suited to the study of Pavlovian conditioning.

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)

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.

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.

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 Handbook of International Psychology Ethics discusses the most central, guiding principles of practice for mental health professionals around the world. For researchers, practicing mental health professionals, and students alike, the book provides a window into the values and belief systems of cultures worldwide. Chapters cover ethics codes from psychological associations and societies on five continents, translating each code into English and discussing vital questions around how the code is put into practice, what it means to association members and society (...) at large, as well as how the code was developed within its unique historical, political, and cultural 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)

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.

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)

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)

In spite of a continuing long and rich history of caring for patients, many nurses have not been satisfied with their work. One cause among others for this dissatisfaction is that nurses often do not care for one another. The philosophy of a Buddhist Sangha, or community, is similar to the philosophy of western communitarian ethics. Both philosophies emphasize the importance of people working together harmoniously towards a common good. In this article, unsatisfactory nurse-nurse relationships have been considered and a (...) model for communitarian nursing practice has been suggested based on a Buddhist Sangha. (shrink)
