ABSTRACTThe visual system has been found to prioritise emotional stimuli so robustly that their presence can temporarily “blind” people to non-emotional targets in their direct line of vision. This...

Food-specific inhibition training (FSIT) is a computerised task requiring response inhibition to energy-dense foods within a reaction-time game. Previous work indicates that FSIT can increase the number of healthy foods (relative to energy-dense foods) children choose, and decrease calories consumed from sweets and chocolate. Across two studies, we explored the impact of FSIT variations (e.g., different response signals, different delivery modes) on children’s food choices within a time-limited hypothetical food-choice task. In Study 1, we varied the FSIT Go/No-Go signals to (...) be emotive (happy vs. sad faces) or neutral (green vs. red signs). One-hundred-and-fifty-seven children were randomly allocated to emotive-FSIT, neutral-FSIT, or a non-food control task. Children participated in groups of 4–15. No significant FSIT effects were observed on food choices (all values ofp> 0.160). Healthy-food choices decreased over time regardless of condition (p 0.050). Healthy choices decreased over time in the control group (p= 0.001) but did not change in the two FSIT groups (bothp> 0.300) supporting previous evidence that FSIT may have a beneficial effect on children’s food choices. Ensuring that children perform FSIT with high accuracy (e.g., by using FSIT in quiet environments and avoiding group-testing) may be important for impacts on food choices though. Future research should continue to explore methods of optimising FSIT as a healthy-eating intervention for children. (shrink)

Objective: To determine whether a moral reasoning exercise can improve response quality to surveys of healthcare priorities Methods: A randomised internet survey focussing on patient age in healthcare allocation was repeated twice. From 2574 internet panel members from the USA and Canada, 2020 (79%) completed the baseline survey and 1247 (62%) completed the follow-up. We elicited respondent preferences for age via five allocation scenarios. In each scenario, a hypothetical health planner made a decision to fund one of two programmes identical (...) except for average patient age (35 vs 65 years). Half of the respondents (intervention group) were randomly assigned to receive an additional moral reasoning exercise. Responses were elicited again 7 weeks later. Numerical scores ranging from –5 (strongest preference for younger patients) to +5 (strongest preference for older patients); 0 indicates no age preference. Response quality was assessed by propensity to choose extreme or neutral values, internal consistency, temporal stability and appeal to prejudicial factors. Results: With the exception of a scenario offering palliative care, respondents preferred offering scarce resources to younger patients in all clinical contexts. This preference for younger patients was weaker in the intervention group. Indicators of response quality favoured the intervention group. Conclusions: Although people generally prefer allocating scarce resources to young patients over older ones, these preferences are significantly reduced when participants are encouraged to reflect carefully on a wide range of moral principles. A moral reasoning exercise is a promising strategy to improve response quality to surveys of healthcare priorities. (shrink)

This article investigates the moderating effects of organizational social consciousness on the natural environmental competency and innovativeness relationship. Organizational social consciousness reflects the organization’s awareness of its place and contribution to the larger system in which it exists and is developed through an organization’s social responsibility, ethics, culture, corporate values, and the view of its stakeholders. Through our study of key strategic decision makers from organizations located in the USA, we operationalize organizational social consciousness and demonstrate the efficacy of this (...) construct in relation to the organizational-level constructs of environmental management competency and innovativeness. Our results reveal that organizational social consciousness positively strengthens the natural environmental competency to organizational innovativeness relationship. (shrink)

In response to nutrient limitation, many animals, including Caenorhabditis elegans, slow or arrest their development. This process requires mechanisms that sense essential nutrients and induce appropriate responses. When faced with nutrient limitation, C. elegans can induce both short and long‐term survival strategies, including larval arrest, decreased developmental rate, and dauer formation. To select the most advantageous strategy, information from many different sensors must be integrated into signaling pathways, including target of rapamycin (TOR) and insulin, that regulate developmental progression. Here, how (...) nutrient information is sensed and integrated into developmental decisions that determine developmental rate and progression in C. elegans is reviewed. (shrink)

Most jurisdictions require that a mental capacity assessment be conducted using a functional model whose definition includes several abilities. In England and Wales and in increasing number of countries, the law requires a person be able to understand, to retain, to use or weigh relevant information and to communicate one’s decision. But interpreting and applying broad and vague criteria, such as the ability ‘to use or weigh’ to a diverse range of presentations is challenging. By examining actual court judgements of (...) capacity, we previously developed a descriptive typology of justifications used in the application of the Mental Capacity Act criteria. We here critically optimise this typology by showing how clear definitions—and thus boundaries—between the criteria can be achieved if the ‘understanding’ criterion is used narrowly and the multiple rationales that fall under the ability to ‘use or weigh’ are specifically enumerated in practice. Such a typology-aided practice, in theory, could make functional capacity assessments more transparent, accountable, reliable and valid. It may also help to create targeted supports for decision making by the vulnerable. We also discuss how the typology could evolve legally and scientifically, and how it lays the groundwork for clinical research on the abilities enumerated by the MCA. No data are available. This paper does not report any original data. (shrink)

Tests of economic theory often focus on choice outcomes and find significant individual differences in these outcomes. This variability may mask universal psychological processes that lead to different choices because of differences across cultures in the information people have available when making decisions. On this view, decision making research within and across cultures must focus on the processes underlying choice.

Pothos suggests dispensing with the distinction between rules and similarity, without defining what is meant by either term. We agree that there are problems with the distinction between rules and similarity, but believe these will be solved only by exploring the representations and processes underlying cases purported to involve rules and similarity.

The spatial organization of the genome is intimately linked to its biological function, yet our understanding of higher order genomic structure is coarse, fragmented and incomplete. In the nucleus of eukaryotic cells, interphase chromosomes occupy distinct.

The present study examined the attitudes of Filipino middle school students toward physical education and the associations between PE attitude and various personal and external correlates of PE. In total, 659 middle school students, aged between 12 and 19 years, participated in the study. The Physical Education Attitude Scale was used to measure affective, cognitive, and motivational/behavioral attitudes of adolescent students toward PE. Results showed that middle school students had moderate general attitudes toward PE. Female students had more favorable attitudes (...) toward PE when their teacher was male than female. When the teacher was female, male students were more satisfied with the PE curriculum than female students. When the teacher was male, female students were more comfortable with the PE curriculum than male students. Finally, students' PE attitude did not decrease as they got older, regardless of student sex. The findings provide a different perspective for the field and underscore the importance of not only the PE curriculum but also the student–teacher relationship. To prevent the decline in students' positive attitude and encourage positive behaviors toward PE and activities, teachers should be very considerate about their interactions with students of the same sex; school administrators, meanwhile, should focus at providing PE teachers with special training courses to enhance both their teaching and communication capabilities.

Different aspects of people's interactions with money are best conceptualized using the drug and tool theories. The key question is when these models of money are most likely to guide behavior. We suggest that the Drug Theory characterizes motivationally active uses of money and that the Tool Theory characterizes behavior in motivationally cool situations. (Published Online April 5 2006).

Pickering & Garrod (P&G) suggest that communicators synchronize their processing at a number of linguistic levels. Whereas their explanation suggests that representations are being compared across individuals, there must be some representation of all conversation participants in each participant's head. At the level of the situation model, it is important to maintain separate representations for each participant. At other levels, it seems less crucial to have a separate representation for each participant. This analysis suggests that different mechanisms may synchronize representations (...) at different linguistic levels. (shrink)

Inclusive single jet production in hadron collisions is considered. It is shown that the QCD parton model predicts a nonmonotonic dependence of the inclusive cross section on the fraction of the energy deposited in the jet registered, if it is normalized on the same cross section measured at another collision energy. Specifically, if the cross section is normalized by the one measured at a higher collision energy, it possesses a minimum which depends on jet rapidity. This prediction can be tested (...) at the Fermilab Tevatron, at the CERN LHC, and at the Very Large Hadron Collider under discussion. (shrink)

In diffusion creep, the contribution of grain-boundary sliding to the overall strain o s can be evaluated in arbitrary polycrystals, if the angular distribution of grain boundaries is known. A o s value of 0.5 is obtained for two-dimensional equiaxed microstructures consisting of regular hexagonal grains, equiaxed grains grown from a Voronoi structure or grains having a circular distribution of grain-boundary angles. The o s value is also evaluated for uniaxially deformed 2D microstructures, both diffusionally and uniformly deformed. For the (...) former, the deformed microstructure is obtained by the simulation of microstructural evolution in polycrystals with straight grain boundaries. The o s value increases gradually with increasing or decreasing strain and is larger in the diffusionally deformed microstructures than in the uniformly deformed microstructures for a given grain aspect ratio. The o s value for three-dimensional polycrystalline microstructures is also obtained from an ellipsoidal distribution of grain-boundary angles. The resultant o s value is 0.60 for 3D equiaxed polycrystals and increases gradually with increasing strain. (shrink)

As the issue of food safety became one of the important public agenda, consumer concern for food safety became the general public concern. The Korea U.S. Free Trade Agreement (KORUS FTA) completion allowing import of U.S. beef to Korea has turned into a massive public uproar and a series of demonstrations, revealing widespread concerns on the part of Korean producers and consumers about government food safety regulations and mishandling of the beef trade requirement. The mishandling of public concerns for BSE (...) on U.S. beef import by the administrators led to a breakdown of the relationship between the public and the government and a loss of consumer confidence in Korea’s food safety system. The KORUS FTA beef crisis raised the issues of government accountability and the importance of understanding moral and ethical aspects of food safety management that pose perceived risk for BSE by the Korean citizen. The aim of this paper is to address the importance of understanding consumer concerns, food ethics and of appropriate risk communication in dealing with politically and publically sensitive food safety issues. This is achieved by assessing the factors that contributed to the conflict between the Korean government and the Korean public over the KORUS FTA beef agreement. (shrink)

Religious and Ethical Perspectives on Global Migration examines the complicated social ethics of migration in today's world. Editors Elizabeth W. Collier and Charles R. Strain bring the perspectives of an international group of scholars toward a theory of justice and ethical understanding for the nearly two hundred million migrants who have left their homes seeking asylum from political persecution, greater freedom and safety, economic opportunity, or reunion with family members.

Editors’ Note:As a matter of policy, the editors believe that publishing several reviews of selected texts is a valuable exercise which will enable a cross-section of views to be aired. The recently published second edition of the National Academy of Sciences’ report “On Being a Scientist” was considered an appropriate text for such treatment. The reviewer, Kenneth D. Pimple, Ph.D., is a Research Associate at the Poynter Center for the Study of Ethics and American Institutions and a Visiting Lecturer in (...) the American Studies Program, both at Indiana University. He has been involved with training faculty members to teach ethics since 1989 and is the project director of “Teaching Research Ethics: A Workshop at Indiana University,” with funding from the Department of Education’s Fund for the Improvement of Postsecondary Education. Her interests include nerve development and regeneration. Her research is in the area of analytical chemistry and emphasizes spectroscopic techniques. (shrink)

Reproductive senescence in human females takes place long before other body functions senesce. This fact presents an evolutionary dilemma since continued reproduction should generally be favored by natural selection. Two commonly proposed hypotheses to account for human menopause are (a) a recent increase in the human lifespan and (b) a switch to investment in close kin rather than direct reproduction. No support is found for the proposition that human lifespans have only recently increased. Data from Ache hunter-gatherers are used to (...) test the kin selection hypothesis. Ache data do not support the proposition that females can gain greater fitness benefits in old age by helping kin rather than continuing to reproduce. Nevertheless, one crucial parameter in the model, when adjusted to the highest value within the measured 95% confidence interval, would lead to the evolution of reproductive senescence at about 53 years of age. Further investigation is necessary to determine whether the kin selection hypothesis of menopause can account for its current maintenance in most populations. (shrink)

In this paper I develop three conceptions of the relationship between evolutionary and developmental biology. I further argue that: (a) the choice between them largely turns on as yet unresolved empirical considerations; (b) none of these conceptions demand a fundamental conceptual reevaluation of evolutionary biology; and (c) while developmental systems theorists have constructed an important and innovative alternative to the standard view of the genotype/phenotype relations, in considering the general issue of the relationship between evolutionary and developmental biology, we can (...) remain neutral on this debate.

Aggleton & Brown (A&B) propose that the hippocampal-anterior thalamic and perirhinal-medial dorsal thalamic systems play independent roles in episodic memory, with the hippocampus supporting recollection-based memory and the perirhinal cortex, recognition memory. In this commentary we discuss whether there is experimental support for the A&B model from studies of long-term memory in semantic dementia.

Anyone who studies antiquity is surely accustomed to the tenuousness and often wild variances of the dating of many of our texts. But even if this is taken for granted, the dating of Demetrius' On Style seems more problematic than most: the text has been assigned a date anywhere from the late fourth century B.c. to the late first century C.e. Attempts to narrow this wide range have been made using internal linguistic data, but these have not proved definitive, although (...) a late date is now tentativel accepted by most. But a possibly more convincing argument for a late date may be found in a reference to architecture in paragraph 13 of On Style. (shrink)
