Neurosensory hearing loss is a growing problem of super‐aged societies. Cochlear implants can restore some hearing, but rebuilding a lost hearing organ would be superior. Research has discovered many cellular and molecular steps to develop a hearing organ but translating those insights into hearing organ restoration remains unclear. For example, we cannot make various hair cell types and arrange them into their specific patterns surrounded by the right type of supporting cells in the right numbers. Our overview of the topologically (...) highly organized and functionally diversified cellular mosaic of the mammalian hearing organ highlights what is known and unknown about its development. Following this analysis, we suggest critical steps to guide future attempts toward restoration of a functional organ of Corti. We argue that generating mutant mouse lines that mimic human pathology to fine‐tune attempts toward long‐term functional restoration are needed to go beyond the hope generated by restoring single hair cells in postnatal sensory epithelia.

Knowing the factors that executives deem critical to governance change can improve our understanding of how such changes come about and can help us evaluate those changes. Interviews with business and finance executives at 11 colleges reveal the importance to governance change of chief executive and board member leadership and interactions, as well as executive communication style. Costs are clear constraints to action, particularly since benefits are not quantified and are difficult to describe. Efforts to discuss governance with internal stakeholders (...) require persistence to overcome narrow, individualized concerns. Communication about governance to external stakeholders is rare and represents a missed opportunity for stakeholder feedback and the development of trust. Executives appear willing to adopt governance forms without considering the idiosyncrasies of their institutional field, limiting the working definition of governance and its potential. For corporations and not‐for‐profit enterprises these findings hold implications for the context in which leadership is exercised and the shape of governance structures. They also pose a fundamental ethical dilemma for leaders to address. (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 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.

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)

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)

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)

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.

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.

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.

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)

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.

What has not yet been imagined in thought is: how to remain together while still being two, how to be and become subjectively two, how to discover a way of coexisting as two beings … a way of living and thinking and loving as two beings without one being reduced to the other? … [t]hanks to the respect that I feel for the other as other, to articulate both attraction and restraint with respect to him. I go out from and (...) return to myself in order to respect his alterity, and this respect for the other becomes respect for myself, my life and my growth. So there is no longer fusion or submission, but the existence of a two which is irreducible to one or to the simple opposition between one (male) and the other (female), a reduction which makes them simply two poles of the one.

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)

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.

In the superannuation/pension industry, ordinary investors entrust their retirement savings to the trustees of the superannuation plan. Investors rely on the trustees to ensure that ethical business and risk management practices are implemented to protect their retirement savings. Governance practices ensure the monitoring of ethical risk management (Drennan, L. T.: 2004, Journal of Business Ethics 52, 257-266). The Australian superannuation industry presents a unique scenario. Legislation requires employers to contribute a minimum of 9% of the employees wage to retirement savings. (...) However, there are no legislated governance standards, although there are standards of recommended governance practices. In this article, we examine the level of voluntary adoption of governance practices by the trustees of Australian public sector and industry superannuation funds. We also assess whether superannuation governance practices are associated with performance and volatility /riskiness of returns. Survey results show that the majority of superannuation plans adopt recommended governance practices supporting the concept of ethical management of the member's retirement savings. The examination of governance principles that impact returns and risk shows that board size and regular review of conflicts are positively associated with return. Superannuation plans with higher volatility in returns meet more frequently. (shrink)

This research presents the results of an exploratory empirical study that assessed perceived organizational preparedness for coping with a major crisis or disaster. A scale was developed and tested to measure perceptions of organizational preparedness. Hypotheses were tested to examine variations in perception of crisis preparedness. Potential for occurrence of crises was also examined and demographics collected. Findings indicate that top-level and middle-level managers have a higher level of perceived preparedness than employees, no differences in perceived preparedness based on size (...) of the city where organizations operate, government organizations expressed a higher perception of crisis preparedness than for-profit organizations, and the highest perception of preparedness was exhibited by organizations employing more than 500 employees.

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)
