Quantity discrimination in Tenebrio molitor: evidence of numerosity discrimination in an invertebrate?

Numerosity discrimination, the ability to distinguish between sets with more and less items, is recognised as the foundation for higher numerical abilities. Understanding numerosity discrimination from a comparative perspective is hence pivotal in tracing the evolution of numerical representation systems. However, numerosity discrimination has been well studied only in vertebrates, where two innate systems of number representation have been described: an ‘analog magnitude system’ used to discriminate among numerosities by representing them as cardinal magnitudes and a ‘parallel individualisation system’ that allows precise discrimination among small arrays of items (≤4) by representing objects individually. We investigated the existence of quantity discrimination in an insect species (Tenebrio molitor) by using a spontaneous two-choice procedure in which males were exposed to substrates bearing odours from different numbers of females (≤4) in increasing numerosity ratios (1:4, 1:3 and 1:2). We show that males can discriminate sources of odours reflecting 1 versus 4 and 1 versus 3 females, but not 2 versus 4 or 1 versus 2, indicating that T. molitor males exhibit a marked preference for sources reflecting more female donors only when numerosity ratios are below 1:2. We discuss the functional significance of this finding and whether our pattern of results could be best explained by summation of a non-numerical continuous variable or by the existence of a numerosity discrimination mechanism with an operational signature ratio of 1:2.     

Is There an Identity Crisis in Environmental Ethics?

Environmental ethics is both a moral philosophy and an applied ethics.This duality has led some people to feel confused about environmental ethics' identity and to cast doubts on its legitimacy.This paper,by distinguishing and exploding environmental ethics' two patterns of inquiry (the moral philosophy pattern and the applied ethics pattern) and their characteristics,tries to resolve the discipline's identity crisis and to argue for its legitimacy.     

Perceptions of South Florida Hispanic and Anglo Catholics: From Whom Would They Seek Help?

Hispanic and Anglo Catholics in South Florida who attended Sunday services (N = 473) were surveyed to determine their help-seeking preferences for moral concerns, mental disorders, and practical life/family problems. Respondents were asked to indicate whether they would seek help from a priest; a priest with a degree and license in one of the helping professions (clinical social work, psychology, psychiatry, or mental health counseling); a layperson with a degree and license in one of the helping professions (clinical social work, psychology, psychiatry, or mental health counseling); or if they believed they could deal with the situation without external assistance. The findings suggest that Anglo Catholics prefer assistance from a person who was credentialed in one of the helping professions, whereas Hispanic Catholics would seek help from a priest with or without a background in the helping professions.     

How Clearly Must I See? Art and Ethics in Pedagogical Practice

This essay explores pedagogical practices and ethical obligations in the embrace of cultural and religious diversity by a faculty team in a theological school course. Attention is given to the interplay of art and ethical dilemmas in an educational praxis that calls into question students’ taken‐for‐granted worldviews and theologies. In the first of three sections the writers identify several assumptions they brought to the conduct of the course regarding diversity, art, and pedagogy. The second section describes student encounters with and responses to art from a variety of cultural contexts. The paper concludes with a critical reflection on ethical and political issues arising from pedagogical practices that engage students with art.     

Value Dissonance and Ethics Failure in Academia: A Causal Connection?

Ethics failure in academia is not new, yet its prevalence, causes, and methods to prevent it remain a matter of debate. The author’s premise is that value dissonance underlies most of the reasons ethics failure occurs. Vignettes are used to illustrate value dissonance at the individual and institutional levels. Suggestions are offered for ways academic institutions can assume greater responsibility as a moral agency to prevent the occurrence of ethics failure.

Who's in Charge?: Coparenting in South and Southeast Asian Families

In light of the evolving roles of parents and the involvement of extended family within Asian cultures, the traditionally Western dyadic coparenting construct must be reconceptualized to include not only the coparenting relationship, but also other caregivers within the coparenting network. Theoretical and empirical evidence on coparental systems are discussed and two studies from South and Southeast Asian cultures are presented to highlight subcultural variations in cocaregiving networks. Results indicated that mothers were the primary caregivers across both cultural contexts. Extended family members assumed important coparental responsibilities in both cultural contexts. These findings highlight the need to reconceptualize and expand the dyadic coparental unit to include extended family members. We also discuss the relevance of the broader coparental network in examining the Asian childs education as well as cognitive and socioemotional development.     

Violence and race in professional baseball: Getting better or getting worse?

The purpose of this study was to examine the relationship between race and violence in the context of professional baseball. Specifically, I used the number of times a batter was hit by a pitch (per plate appearance) as an indicator of being the victim of an indirect violent act. Archival data were gathered from 4,273 players from 1950 to 1997, yielding 27,022 individual records. Even after controlling for player ability and league rules, race was a significant predictor of being hit. Specifically, from 1950 to 1997, the rate at which Blacks were hit was approximately 7.5% greater than the rate for Whites. The rate at which Hispanics were hit was approximately 7.6% greater than the rate for Whites. Testing year as a moderator revealed that the Black‐White difference was much greater in the 1950s and 1960s. From 1970 to 1989, race was not a significant predictor of being hit. Contrary to the hypotheses, from 1990 to 1997, Whites and Hispanics were hit at a significantly higher rate than Blacks (23.0% and 29.0%, respectively). Additional analyses revealed no relationship between pitcher race and batter race in hit‐by‐pitch events from 1997 to 1999. The findings are discussed with respect to group threat theory and the distinction between covert and overt aggression. Aggr. Behav. 28:109–116, 2002. © 2002 Wiley‐Liss, Inc.     

Are Ethics Training Programs Improving? A Meta-Analytic Review of Past and Present Ethics Instruction in the Sciences

Given the growing public concern and attention placed on cases of research misconduct, government agencies and research institutions have increased their efforts to develop and improve ethics education programs for scientists. The present study sought to assess the impact of these increased efforts by sampling empirical studies published since the year 2000. Studies published prior to 2000 examined in other meta-analytic work were also included to provide a baseline for assessing gains in ethics training effectiveness over time. In total, this quantitative review consisted of 66 empirical studies, 106 ethics courses, 150 effect sizes, and 10,069 training participants. Overall, the findings indicated that ethics instruction resulted in sizable benefits to participants and has improved considerably within the last decade. A number of specific findings also emerged regarding moderators of instructional effectiveness. Recommendations are discussed for improving the development, delivery, and evaluation of ethics instruction in the sciences.     

An Existential Foundation for an Ethics of Care in Heidegger’s Being and Time

Martin Heidegger’s existential account of care in Being and Time (2010) provides us with an opportunity to reimagine what the proper theoretical grounding of an ethic of care might be. Heidegger’s account of care serves to deconstruct the two primary foundations that an ethic of care is often based upon. Namely, that we are inevitably interdependent upon one another and/or possess an innate disposition to care for fellow humans in need. Heidegger’s account reveals that both positions are founded upon an ontic (meaning factual existence), as opposed to an ontological (which refers to the nature of being), understanding of care. The distinctions between an ontic and ontological understanding of care are significant. Yet, I maintain that they are not completely incompatible. Both Heidegger and care ethicists contend that our existence with others is understood through a relational ontology. Furthermore, there are certain ontological structures from Heidegger which resonate with an ethic of care. Two key existential structures are leaping-ahead and being-guilty. These existential structures are latent in care ethics, and by explicitly revealing them I reinforce the connection between Heidegger’s account and care theory. Lastly, I develop the theoretical foundations of care ethics by proposing an existential ethic of care.

     

Who is crossing where? Infants' discrimination of figures and grounds in events

To learn relational terms such as verbs and prepositions, children must first dissect and process dynamic event components. This paper investigates the way in which 8- to 14-month-old English-reared infants notice the event components, figure (i.e., the moving entity) and ground (i.e., stationary setting), in both dynamic (Experiment 1) and static representations of events (Experiment 2) for categorical ground distinctions expressed in Japanese, but not in English. We then compare both 14- and 19-month-old English- and Japanese-reared infants’ processing of grounds to understand how language learning interacts with the conceptualization of these constructs (Experiment 3). Results suggest that (1) infants distinguish between figures and grounds in events; (2) they do so differently for static vs. dynamic displays; (3) early in the second year, children from diverse language environments form nonnative – perhaps universal – event categories; and (4) these event categories shift over time as children have more exposure to their native tongue.     

Ethics and Science: Is Plausibility in the Eye of the Beholder?

This paper argues that morality is objective in a specific sense that accords with a broadly expressivist stance in metaethics. The paper also explains that although there is a kind of subjectivity in moral inquiry, the same holds for other kinds of normative inquiry, including epistemic and even scientific inquiry, and moreover that this kind of subjectivity is no threat to morality’s objectivity. The argument for the objectivity of morality draws strong parallels between ethics, epistemology, and science, but does not depend on equally strong parallels between ethics and mathematics. I argue that there is more to learn from a comparison between ethics and mathematics than I used to think, but the difference between the issues that come up in thinking about objectivity in ethics and those that come up in thinking about objectivity in mathematics is substantial, and we cannot carry over results from the philosophy of mathematics to the case of morality.

Is There an Ethics of Diabolical Evil? Sex Scandals, Family Romance, and Love in the School & Academy

This essay attempts to examine the difficult question of sex scandals both in public school settings and in the academy. It raises issues over the way authority in the classroom is unequally exercised by both male and female teachers in terms of power and seduction. However, the Law remains explicit when it comes to judging who is at fault within a-student relationship that collapses into the bedroom. The ethics that surround such sexual affairs is raised through the psychoanalytic and philosophical writings of Jacques Lacan. The essay ends by offering a surprised perspective over the question whether an ethics of diabolical evil is possible, given that such affairs are differentiated as post-Oedipal relationships where age differentiations have become blurred.     

Just Sustainability? Sustainability and Social Justice in Professional Codes of Ethics for Engineers

Should environmental, social, and economic sustainability be of primary concern to engineers? Should social justice be among these concerns? Although the deterioration of our natural environment and the increase in social injustices are among today’s most pressing and important issues, engineering codes of ethics and their paramountcy clause, which contains those values most important to engineering and to what it means to be an engineer, do not yet put either concept on a par with the safety, health, and welfare of the public. This paper addresses a recent proposal by Michelfelder and Jones (2011) to include sustainability in the paramountcy clause as a way of rectifying the current disregard for social justice issues in the engineering codes. That proposal builds on a certain notion of sustainability that includes social justice as one of its dimensions and claims that social justice is a necessary condition for sustainability, not vice versa. The relationship between these concepts is discussed, and the original proposal is rejected. Drawing on insights developed throughout the paper, some suggestions are made as to how one should address the different requirements that theory and practice demand of the value taxonomy of professional codes of ethics.     

Between an Example and a Precept,Which Has Greater Importance? A Comparison of the Channels of Socialization in Military Ethics

In this study, I examined what channels of socialization influence the moral behavior of cadets. We conducted a regression analysis of the effects of parents' attitudes to moral education, the standard and potential curriculum of schools, peer groups, and communication media on individual ethics and discipline using 399 sample participants. The participants were recruited through a questionnaire survey on cadets from academy of military, naval, and air force, and four-year based students from R.O.C. National Defense University. The analysis results showed that the cultivation of morality among cadets was directly influenced by the school's potential curriculum (i.e., intern cadres and officers in company) and their parents' attitudes to moral education during early childhood. The results also indicated that the influence of teaching by example was more significant than that of teaching by precept.

Fairness or discrimination in intergroup behaviour? a reply to Branthwaite,Doyle and Lightbown

Branthwaite, Doyle and Lightbown (1979) argue that minimal intergroup behaviour represents a compromise or balance between fairness and discrimination, that fairness and discrimination are opposed, generic norms of intergroup relations and that one factor affecting their relative weight is status position since, apparently, different status groups attempt to equalize their positions by varying the degree to which they are fair or discriminatory. This reply reviews evidence to show that minimal groups are never fair but always discriminatory to varying degrees and that a generic norm of intergroup fairness is unnecessary to explain why that discrimination rarely approaches maximum. It also argues that the concept of opposed, generic norms has neither empirical nor theoretical value. Finally, it cites findings that the basic tendency in intergroup behaviour is not to equalize but to accentuate evaluative differences between groups (whether of similar or different status) in favour of the ingroup.     

Role of Hindsight Bias,Ethics, and Self-Other Judgments in Students’ Evaluation of an Animal Experiment

Does hindsight knowledge make research seem more ethical and predictable? In line with the notion of hindsight bias, students in 3 experiments knowing the outcome of an animal experiment judged the results as more foreseeable and ethical relative to students who did not know the outcome. Via self to other comparisons, students evaluate themselves more favorably compared to a peer but exhibited hindsight bias in doing so. Uniquely, the findings reveal the possibility that students deem themselves to be more skeptical and objective than their peers. Implications for teaching animal ethics and for Institutional Review Boards are discussed.     

Ethics in Community-University-Artist Partnered Research: Tensions,Contradictions and Gaps Identified in an ‘Arts for Social Change’ Project

Academics from diverse disciplines are recognizing not only the procedural ethical issues involved in research, but also the complexity of everyday “micro” ethical issues that arise. While ethical guidelines are being developed for research in aboriginal populations and low-and-middle-income countries, multi-partnered research initiatives examining arts-based interventions to promote social change pose a unique set of ethical dilemmas not yet fully explored. Our research team, comprising health, education, and social scientists, critical theorists, artists and community-activists launched a five-year research partnership on arts-for-social change. Funded by the Social Science and Humanities Research Council in Canada and based in six universities, including over 40 community-based collaborators, and informed by five main field projects (circus with street youth, theatre by people with disabilities, dance for people with Parkinson’s disease, participatory theatre with refugees and artsinfused dialogue), we set out to synthesize existing knowledge and lessons we learned. We summarized these learnings into 12 key points for reflection, grouped into three categories: community-university partnership concerns (n?=?3), dilemmas related to the arts (n?=?5), and team issues (n?=?4). In addition to addressing previous concerns outlined in the literature (e.g., related to consent, anonymity, dangerous emotional terrain, etc.), we identified power dynamics (visible and hidden) hindering meaningful participation of community partners and university-based teams that need to be addressed within a reflective critical framework of ethical practice. We present how our team has been addressing these issues, as examples of how such concerns could be approached in community-university partnerships in arts for social change.     

How international transracial adoptees and immigrants cope with discrimination? The moderating role of ethnic identity in the relation between perceived discrimination and psychological well‐being

Research has consistently shown that discrimination based on ethnic group membership affects the psychological well‐being of ethnic minorities. Recent studies revealed that discrimination is also a relevant experience for international transracial adoptees, who have experienced a unique migration process. Yet, there is still a paucity of studies focused on similarities and differences between how immigrants and international transracial adoptees perceive discrimination and on how perceived discrimination impacts psychological well‐being, also depending on ethnic identity. Our study aimed to fill these gaps by investigating the moderating role of ethnic identity affirmation in the association between perceived discrimination and psychological well‐being, measured in terms of self‐esteem. A comparison between international transracial adoptees and immigrants was carried out in the Italian context. Participants were 119 international transracial adoptees and 90 immigrants, aged between 15 and 24, all categorizing themselves as Latinos. Findings revealed that immigrants perceived more discrimination and showed higher levels of ethnic identity affirmation than did adoptees, but no difference emerged with respect to self‐esteem. Ethnic identity affirmation buffered the detrimental effects of perceived discrimination on self‐esteem among international transracial adoptees but not among immigrants. Results are discussed in relation to practical implications for preventive interventions.
