Aging at work is a dynamic process. As individuals age, their motives, abilities and values change as suggested by life-span development theories (Kanfer & Ackerman, 2004; Lang & Carstensen, 2002). Their growth and extrinsic motives weaken while intrinsic motives increase (Kooij, De Lange, Jansen, Kanfer, & Dikkers, 2011), which may result in workers investing their resources in different areas accordingly. However, there is significant individual variability in aging trajectories (Hedge, Borman, & Lammlein, 2005). In addition, the changing nature of work, (...) the evolving job demands, as well as the available opportunities at work may no longer be suitable for older workers, increasing the likelihood of person-job misfit. The potential misfit may, in turn, impact how older workers perceive themselves on the job, which leads to conflicting work identities. With the traditional job redesign approach being a top-down process, it is often difficult for organizations to take individual needs and skills into consideration and tailor jobs for every employee (Berg, Dutton, & Wrzesniewski, 2010). Therefore, job crafting, being an individualized process initiated by employees themselves, can be a particularly valuable mechanism for older workers to realign and enhance their demands-abilities and needs-supplies fit. Through job crafting, employees can exert personal agency and make changes to the task, social and cognitive aspects of their jobs with the goal of improving their work experience (Wrzesniewski & Dutton, 2001). Building on the Life Span Theory of Control (Heckhausen & Schulz, 1995), we posit that job crafting, particularly cognitive crafting, will be of increasing value as employees age. Through reframing how they think of their job and choosing to emphasize job features that are personally meaningful, older workers can optimize their resources to proactively redesign their jobs and maintain congruent, positive work identities.

SummaryIntense, sustained nursing lengthens inter-birth intervals and is causally linked with low natural fertility. However, in traditional settings, the effects of such nursing on fertility are difficult to disentangle from those of nutrition. Results from an prospective, direct observational study of reproductive function in well-nourished Amele women who nurse intensively and persistently but who also have high fertility are here presented. Endocrine measures show that ovarian activity resumes by median 11·0 months postpartum. Median duration of postpartum amenorrhoea is 11·3 months, (...) time to next conception is 19·0 months, and the inter-birth interval is 28·0 months. Average life time fertility is 6·8. High fertility in Amele women is due both to refractoriness of reproductive function to suckling stimuli, and to maintenance of equivalent age-specific fertility rates across the reproductive life span.

Many analysts argue that environmental regulation is a barrier to innovation in business firms. A competing view holds that environmental regulation contributes to firm level innovation. This article attempts to partially reconcile these two views. The article argues that organizational and individual level variables moderate the effect of environmental regulation generally on the radicalness of innovation at the firm level. It proposes that four moderating variables the degree to which information analysis about environmental issues is centralized, firm size, the intensity (...) and integration of research and development (R&D) units within the firm, and whether regulation is perceived as an opportunity change the sign of the relationship between environmental regulation and the radicalness of firm level innovation. Empirically testable propositions are presented and a regulation innovation profile is suggested. Directions for future research and implications for practicing managers are highlighted. (shrink)

:A norm of equal treatment is cited regularly in the American jurisprudence of property “takings” under the Fifth and Fourteenth Amendments to the Constitution, as a benchmark of fair treatment of owners. According to an increasingly prevalent version of this equality norm, courts should look to parity of treatment among property owners in investigating whether particular regulations “take” property. This essay argues, however, that such an equality norm is misplaced, and that courts should judge fairness by the criterion of expectation—including (...) reasonable expectations of regulation.A norm of equality becomes problematic in the face of the economic theory of the evolution of property. This theory posits that as resources become more congested, their uses carry increasing common pool costs or “externalities”—a scenario that should predictably result in more stringent resource management—up to and including the establishment of regulatory regimes as well as property rights themselves. This evolutionary pattern, however, places earlier and later resource users in different positions vis-à-vis both common pool externalities and regulatory responses, and their different temporal positions fragment the meaning of equal treatment and destabilize it as a jurisprudential norm. This essay argues that while equal treatment may be a benchmark for special or invidious cases, like those relating to civil rights, the great bulk of takings cases involve regulatory responses to congesting resources, where a norm of equal treatment breaks down. Thus, in seeking fair treatment, takings jurisprudence should downplay equality and instead look to the understanding of property as a basis of expectations—but those expectations should include the anticipation of reasonable regulatory responses to resource congestion.

This paper discusses how Salvadoran companies practice corporate philanthropy in El Salvador, and what might motivate it. First, I briefly discuss three principal theories of corporate philanthropy, and explore some current trends in international corporate philanthropy to highlight some of the motives Salvadoran companies may have to participate in charitable activities. Then, I discuss the history of the Salvadoran private sector to help us understand philanthropic activity today. Next, I suggest that philanthropic acts by Salvadoran firms are driven by altruistic (...) and politically strategic motives, and reflect individualistic and paternalistic attitudes. In the discussion, I include examples of Salvadoran corporate philanthropy as it is practiced today, based on recent field research in El Salvador. (shrink)

Behavioral weight loss interventions that promote healthy eating as a way to achieve and maintain healthy weights do not work for most people. Most participants encounter significant challenges to behavior change and do not lose weight or maintain meaningful weight loss. For some, there may be negative consequences of participating in a BWLI, including social, psychological and economic costs. The literature is largely silent on these negative unintended consequences, but they are important for both practical and ethical reasons. If efforts (...) to eat healthier have too many negative consequences for individuals and groups, then these efforts are unlikely to be effective, and promoting them may not always be ethical; this would boost the case for moving away from individual-focused efforts as part of healthy eating efforts. Alternatively, if we can make BWLI interventions more effective and more ethical by mitigating these unintended consequences, then it may be too soon to give up on individual-focused efforts. We make a case for systematic assessment and reporting of the unintended consequences of BWLI. This could contribute to more effective and ethical BWLI and inform obesity interventions and policies more broadly. (shrink)

Ethical decision-making in public health rarely involves simply avoiding a bad choice in favor of a good choice. Instead, it requires policymakers to strike a balance among conflicting goals that are all good—goals such as the health of populations and individuals, knowledge gained through scientific research, autonomy, social justice, and the efficient use of limited resources. This balance can be elusive, and perfect examples are the legal instruments governing dual-use research, a term describing scientific endeavors meant to produce beneficial knowledge (...) or technology, but that could also be misapplied. Dual-use research of concern policies were implemented... (shrink)

We investigate the dynamics of sensory integration for perceiving musical performance, a complex natural behavior. Thirty musically trained participants saw, heard, or both saw and heard, performances by two clarinetists. All participants used a sliding potentiometer to make continuous judgments of tension (a measure correlated with emotional response) and continuous judgments of phrasing (a measure correlated with perceived musical structure) as performances were presented. The data analysis sought to reveal relations between the sensory modalities (vision and audition) and to quantify (...) the effect of seeing the performances on participants' overall subjective experience of the music. In addition to traditional statistics, functional data analysis techniques were employed to analyze time-varying aspects of the data. The auditory and visual channels were found to convey similar experiences of phrasing but different experiences of tension through much of the performances. We found that visual information served both to augment and to reduce the experience of tension at different points in the musical piece (as revealed by functional linear modeling and functional significance testing). In addition, the musicians' movements served to extend the sense of phrasing, to cue the beginning of new phrases, to indicate musical interpretation, and to anticipate changes in emotional content. Evidence for an interaction effect suggests that there may exist an emergent quality when musical performances are both seen and heard. The investigation augments knowledge of human communicative processes spanning language and music, and involving multiple modalities of emotion and information transfer. (shrink)

Seminal work by Knobe, Prasada, and Newman (2013) distinguished a set of concepts, which they named “dual‐character concepts.” Unlike traditional concepts, they require two distinct criteria for determining category membership. For example, the prototypical dual‐character concept “artist” has both a concrete dimension of artistic skills, and an abstract dimension of aesthetic sensibility and values. Therefore, someone can be a good artist on the concrete dimension but not truly an artist on the abstract dimension. Does this analysis capture people's understanding of (...) cornerstone social categories, such as gender, around which society and everyday life have traditionally been organized? Gender, too, may be conceived as having not only a concrete dimension but also a distinct dimension of abstract norms and values. As with dual‐character concepts, violations of abstract norms and values may result in someone being judged as not truly a man/woman. Here, we provide the first empirical assessment of applying the dual‐character framework to people's conception of gender. We found that, on some measures that primarily relied on metalinguistic cues, gender concepts did indeed resemble dual‐character concepts. However, on other measures that depicted transgressions of traditional gender norms, neither “man” nor “woman” appeared dual‐character‐like, in that participants did not disqualify people from being truly a man or truly a woman. In a series of follow‐up studies, we examined whether moral norms have come to replace gender role norms for the abstract dimension. Implications for the evolution of concepts and categories are explored. (shrink)

Recent reports of the discovery of a “God module” in the human brain derive from the fact that epileptic seizures in the left temporal lobe are associated with ecstatic feelings sometimes described as an experience of the presence of God. The brain area involved has been described as either (a) the seat of an innate human faculty for experiencing the divine or (b) the seat of religious delusions.In fact, religious experience is extremely various and involves many parts of the brain, (...) including some that are prehuman in their evolutionary history and some that are characteristically human. In the continuing integration of such experiences, spiritual formation takes place. Thus the entire human brain might be described as a “God module.”Such a process is only possible because of the brain's complexity. The human brain is the most complex entity for its size that we know of. As used here, complexity is a specialized term denoting the presence of a web of interlinked and significant connections—the more intricate the web, the more complex the entity. Complex systems develop only in a milieu that provides both lawfulness and freedom, and they tend to be self‐organizing, becoming more complex and more effective as a result of both inward and outward experience. The evidence suggests that both personal growth and spiritual growth are processes of complexification of character, and of the brain itself. This thesis is tested in light of the work of William James and James W. Fowler. (shrink)

A longitudinal study of 308 white -collar U.S. employees revealed that feelings of hope and gratitude increase concern for corporate social responsibility. In particular, employees with stronger hope and gratitude were found to have a greater sense of responsibility toward employee and societal issues; interestingly, employee hope and gratitude did not affect sense of responsibility toward economic and safety/quality issues. These findings offer an extension of research by Giacalone, Paul, and Jurkiewicz.

Science, technology, engineering, and mathematics disciplines commonly illustrate 3D relationships in diagrams, yet these are often challenging for students. Failing to understand diagrams can hinder success in STEM because scientific practice requires understanding and creating diagrammatic representations. We explore a new approach to improving student understanding of diagrams that convey 3D relations that is based on students generating their own predictive diagrams. Participants’ comprehension of 3D spatial diagrams was measured in a pre- and post-design where students selected the correct 2D (...) slice through 3D geologic block diagrams. Generating sketches that predicated the internal structure of a model led to greater improvement in diagram understanding than visualizing the interior of the model without sketching, or sketching the model without attempting to predict unseen spatial relations. In addition, we found a positive correlation between sketched diagram accuracy and improvement on the diagram comprehension measure. Results suggest that generating a predictive diagram facilitates students’ abilities to make inferences about spatial relationships in diagrams. Implications for use of sketching in supporting STEM learning are discussed. (shrink)

Advanced Cell Technology's Ethics Advisory Board has been called window dressing for a corporate marketing plan. But the scientists and managers have paid attention, and the lawyers have gone along.

The pluralism of methodologies and severe time constraints pose important challenges to pedagogy in clinical ethics. We designed a step-by-step student handbook to operate within such constraints and to respect the methodological pluralism of bioethics and clinical ethics. The handbook comprises six steps: Step 1: What are the facts of the case?; Step 2: What are your obligations to your patient?; Step 3: What are your obligations to third parties to your relationship with the patient?; Step 4: Do your obligations (...) converge or conflict?; Step 5: What is the strongest objection that could be made to the identification of convergence in step 4 or the arguments in step 4? How can this objection be effectively countered?; and Step 6: How could the ethical conflict, or perceived ethical conflict, have been prevented? (shrink)
