ABSTRACT The study of voter competence has made significant contributions to our understanding of politics, but at this point there are diminishing returns to the endeavor. There is little reason, in theory or in practice, to expect voter competence to improve dramatically enough to make much of a difference, but there is reason to think that officials? competence can vary enough to make large differences. To understand variations in government performance, therefore, we would do better to focus on the abilities (...) and performance of officials, not ordinary citizens. (shrink)

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 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)

Despite the fact that the High-Church Tory, Mary Astell, held political views diametrically opposed to the Whiggish Catharine Trotter Cockburn and Catharine Macaulay, it is here argued that their metaethical views were surprisingly similar. All were influenced by a blend of Christian universalism and Aristotelian eudaimonism, which accepted the existence of a law of nature, that we strive for happiness, and that happiness results from living in accord with our God-given nature. They differed with regard to epistemological issues; the means (...) by which we can know the law of nature, and with regard to the characterization of that nature; our telos. Traces of the ethical theories developed by these women can also be seen in the works of the philosophically informed novelists, Sarah Fielding, Jane Collier, Sarah Scott, and Hannah More. (shrink)

Dummett's output has been prolific and highly influential, but not always as accessible as it deserves to be. This book sets out to rectify this situation.

This is a timely re-appraisal of feminist political thinkers and their male contemporaries, providing a re-evaluation of feminist humanism.

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.

Roughly 20 percent of organic cropland wasdevoted to produce compared to only 3 percent forconventional agriculture in 1995. At the otherextreme, only 6 percent of organic cropland was incorn production while 25 percent of all croplandproduced corn. Only 30 percent of all organicfarmland was in pasture and rangeland compared to 66percent of all farmland. Clearly, these differencesreflect the greater importance of meat and dairyproduction in agriculture overall than in the organicsubsector. In recent years, the organic industry hasgrown not only in (...) volume but in products offered,moving well beyond fresh produce into dairy, snacks,and frozen foods. The estimated growth in retail salesof organic foods averaged over 20 percent a year forthe last eight years compared to only two percent inthe food industry overall, reaching an estimated $4.5billion in 1998. The mix of commodities produced atthe farm level have and will continue to change inresponse to several dynamic forces, including consumerdemand, regulation, and consolidations, mergers, andmainstream entrants at the farm, manufacturing, andretail levels. Consumer demand for organic foods hasbeen spurred by a number of factors including concernsover pesticide residues on foods, food produced usinggenetically modified organisms (GMOs), and hormones indairy and meat products. These concerns coupled withthe overall increase in demand for convenience foodsexplain the phenomenal recent growth of over 70 percent in sales of organic snacks, candy, and frozenfoods. The result has been increased demand forGMO-free grains for snacks, cereals, soy products, andfeed for dairy cows. The recent allowance by USDA forthe labeling of meat and poultry as organic willaccelerate already heightened demand for organic grainand feed from the organic dairy industry. Although thefastest growth in organic foods has been in categoriesother than produce, clearly produce plays an importantrole in the consumers decision on where to shop, anddemand should increase with the overall increase inthe number of organic consumers. Market outlets nowinclude sophisticated natural food store chains,gourmet specialty stores, and e-commerce, allowing fora broadened array of products. Mainstream agriculturalproducers, manufacturers, and supermarket chains haveentered the organic marketplace at a time of lowprices for commodities at the farm gate, fiercecompetition for retail shelf space, and increasinglysophisticated targeting of consumers. Inevitably,these changes in food products offered and in retailoutlets will lead to an organic agriculture thatincreasingly resembles the conventional foodindustry. (shrink)

What would you do if your neighbors kept their dog permanently caged, never letting her out to exercise or relieve herself, in a crate so narrow that she could not turn around or lie down with her legs outstretched? You'd probably call the police and have them charged with animal cruelty. In California, that is how the vast majority of breeding sows and veal calves are treated -- and it's legal.

An approach to Derrida's différance from the perspective of analytic philosophy of language which attempts to show both how many of Derrida's insights are influenced by analytic philosophy of language and can be related to ideas found in Quine, Wittgenstein, and Dennett, but which ultimately concludes that the linguistic idealism that he promotes is incoherent.

It is argued that it is not enough for feminist standpoint theory to argue that a feminine standpoint is better than a masculine one because of its genesis in female psycho-sexuality, it needs to show that its content is actually objectively more accurate. It then argues that historical feminists, such as Mary Wollstonecraft, have in fact tended to adopt a justice perspective, grounded in reason, which is objectively of greater value than that developed by many male authors, because these historical (...) writers have failed to think that justice is incompatible with feeling and emotion and have attempted to combine the importance of sympathy, empathy, and feeling with the need for equality, liberty, and fairness.

ObjectivesThis pilot study sought to develop and evaluate a novel online group-based intervention to help breast cancer survivors make healthy lifestyle changes intended to yield not only beneficial physical outcomes but also greater behavioral, and psychosocial well-being.MethodsAn exploratory single-arm, mixed-method triangulation design was employed to evaluate the feasibility and preliminary effectiveness of the HLM-ABC intervention for overweight BCSs. Fourteen women participated in the 10-week intervention and completed quantitative measures of the above-mentioned outcomes at baseline, post-treatment, 6-month, and 12-month follow-up time (...) points. Qualitative data were obtained post-treatment via semi-structured interviews and a treatment satisfaction questionnaire.ResultsParticipants lost an average of 2.83% of their baseline weight by 1-year follow-up, equal to a small effect size. Despite achieving only modest weight loss, participants achieved meaningful gains in the form of increased physical activity, discovery of gratifying movement, more intuitive eating habits, greater bodily and emotional awareness, and positive shifts in beliefs about being able to make healthy choices regarding food and physical activity. Furthermore, they demonstrated a slight improvement in body image and described feeling more self-compassionate, empowered, and acknowledging of variables beyond control that can present barriers to change.ConclusionAfter completing a 10-week online program, participants achieved meaningful and lasting changes on a number of healthful indicators, even when this did not correspond with a significant reduction in weight. Findings highlight the complex, multifaceted nature of “health” and lend support for promotion of healthier lifestyle following cancer treatment that encompasses not only physical weight, but also behavior, psychosocial well-being, and circumstances such as life-preserving hormonal treatments.

For many, Simone de Beauvoir's The Second Sex has only historic significance. The aim of this article is to show on the contrary that Beauvoir's philosophy already contains all the elements of contemporary feminism-so much so that it can be taken as its paradigm. Beauvoir's ideas about the self are extremely relevant today. Feminist themes such as the logic of "equality and difference" and identity are interwoven in her thinking in ways that can offer solutions to what seem to be (...) insurmountable dilemmas in modern feminism. The attack on all kinds of essentialism can be reconciled with feminist identity-politics when the latter presents itself as "arts of living.". (shrink)

Summary The enthusiasm of Renaissance humanists for classical learning greatly influenced the development of botany in the late fifteenth and sixteenth centuries. Humanist scholars restored the treatises of Theophrastus, Pliny, Galen and Dioscorides on botany and materia medica to general circulation and argued for their use as textbooks in Renaissance universities. Renaissance botanists' respect for classical precepts and models of the proper methods for studying plants temporarily discouraged the use of naturalistic botanical illustration, but encouraged other techniques for collecting and (...) communicating new observations: herbaria, botanical gardens and field trips.

Humility, properly understood as a sense of one's limits, is one of the goods internal to the practice of health care. Humility in Christian tradition has both a relational aspect and an epistemological aspect. Each of these is evident in the practice of medicine. In its relational aspect, humility includes reverance or awe for the grace and strength of patients and their care-givers, a sense that the care-provider is not self-sufficient but needs the care-receiver, and recognition of the worth of (...) those who are oppressed and outcast. In its epistemological aspect, humility is exhibited in respect for the meaning system of the patient and recognition of the limits of medical paradigms and their need for correction from the patient's perspective. The power wielded by the profession of medicine in contemporary society does not preclude the exercise of humility within the profession.

The author contends that overworking residents cannot be ethically justified. There is evidence that overwork is detrimental both to the resident and to the patient. In addition, thu argument that working long hours is essential to maintain medicine's status as a profession is analyzed. The claim cannot be supported by definitions of professionalism. Although Flexner's definition does specify altruism as an essential component, it does not justify long working hours for residents. Altruism is obligatory in some limited cases, but only (...) when it is required to fulfill some contractual obligation.

Let K be a family of structures, closed under isomorphism, in a fixed computable language. We consider effective lists of structures from K such that every structure in K is isomorphic to exactly one structure on the list. Such a list is called a computable classification of K, up to isomorphism. Using the technique of Friedberg enumeration, we show that there is a computable classification of the family of computable algebraic fields and that with a 0'-oracle, we can obtain similar (...) classifications of the families of computable equivalence structures and of computable finite-branching trees. However, there is no computable classification of the latter, nor of the family of computable torsion-free abelian groups of rank 1, even though these families are both closely allied with computable algebraic fields.

Sir Ernst Gombrich and the Barber from Tuscany In the spirit of Sir Ernst Gombrich, this essay uses an anecdote—a chat between Gombrich and a barber from Tuscany—to illustrate a deeper point, namely, how cultural memory, tradition, and a canon give rise to an implied language of culture and cultural value. Gombrich staunchly defended tradition against relativism. By relativism, he meant something like "radical subjectivism." To his mind, subjectivism (in the cultural and social sense of the term) is not only (...) impossible, since meaning is conferred through culture and society, but it is also dangerous (in the cultural and ethical sense of the term), since it denies the existence of shared values. Against consensus on the one hand and radical subjectivism on the other, Gombrich advocated a middle way: criticism and self-criticism to ensure latitude; the search for "truth" to ensure a limited plurality of interpretations.
