Objectives: The objective of this post hoc exploratory analysis was to examine the relationship between age and measures of cortical excitability and inhibition. Methods: Forty-six participants (24 with major depressive disorder and 22 healthy controls) completed MT, SICI, ICF, and CSP testing in a cross-sectional protocol. Of these 46 participants, 33 completed LICI testing. Multiple linear robust regression and Spearman partial correlation coefficient were used to examine the relationship between age and the TMS measures. Results: In the overall sample of (...) 46 participants, age had a significant negative relationship with motor threshold in both the right (rs = -0.49, adjusted p =.007; β= -0.08, adjusted p=.001) and left (rs = -0.42, adjusted p =.029; β= -0.05, adjusted p=.004) hemispheres. This significant negative relationship of age with motor threshold was also observed in the sample of depressed youth in both the right (rs = -0.70, adjusted p =.002; β= -0.09, adjusted p=.001) and left (rs = -0.54, adjusted p =.034; β= -0.05, adjusted p=.017) hemispheres, but not in healthy controls. In the sample of the 33 participants who completed LICI testing, age had a significant negative relationship with LICI (200 millisecond interval) in both the right (rs = -0.48, adjusted p =.05; β= -0.24, adjusted p=.007) and left (rs = -0.64, adjusted p =.002; β= -0.23, adjusted p=.001) hemispheres. This negative relationship between age and LICI (200 millisecond interval) was also observed in depressed youth in both the right (rs = -0.76, adjusted p =.034; β= -0.35, adjusted p=.004) and left (rs = -0.92, adjusted p =.002; β= -0.25, adjusted p=.001) hemispheres. Conclusion: These findings suggest that younger children have higher motor thresholds. This is more pronounced in depressed youth than healthy controls. LICI inhibition may also increase with age in youth. (shrink)

Societal concerns dictate the need for animal welfare standards and legislation. The public and livestock producers often differ on their views of livestock welfare, and failure to meet public expectations may threaten the “social license to operate” increasing the cost of production and hampering the success of the industry. This study examined public and producer attitudes toward common practices and animal welfare issues in the Australian red meat industry, knowledge of these practices, and public and producer trust in people working (...) the red meat industry using an Australia-wide survey of both the general public and red meat producers. Public participants were recruited using a random digit dialing telephone survey while the red meat producers were randomly selected within a curated database of Australian red meat producers. After controlling for gender and age, there were marked differences between public and producer respondents in 20 of the 27 attitude, trust and knowledge variables studied. Producers reported more positive beliefs in the conditions provided for sheep and beef cattle during sea and land transport, the husbandry practices used in the red meat industry, and red meat attributes regarding human health, environmental impact, animal use and animal welfare. Both public and producers reported similar levels of trust in conventional and commercial media and had similar beliefs about animal rights, prevention of animal cruelty and balancing the welfare of people and animals. The results indicate a polarization between the public and livestock producers in their attitudes toward animal welfare, knowledge of husbandry practices and trust in livestock people. (shrink)

The stated goal of Donna Haraway's “Cyborg feminism” is to liberate sensuality from violence. In examining her book alongside that of Jesuit Toletus it becomes clear that both argue that sensuality is a place of metaphysical violence. The first two sections of the essay demonstrate this, and, in addition that Toletus' commentary on Aquinas is hardly accurate. This fact will help justify the claim that the Jesuit tradition includes a rather particular theory of sensuality, the origin of which is perhaps (...) Giles of Rome. A third section shows how the Jesuit Gaston Fessard rediscovered Aquinas' own theory of sensuality through a thoroughgoing critique of Hegelian and Marxist dialectic. The essay concludes that Haraway would do well to adopt Aquinas' non‐violent theory of sensuality as her own. (shrink)

“ All verbal forms of statement,” says Whitehead, “that have been long before the world disclose ambiguities, and sometimes the ambiguities strike at the very heart of the meaning. The effective sense in which a doctrine has been held in the past cannot be determined by a logical analysis of statements made in ignorance of the logical trap.... Religion collapses unless its main positions command immediacy of assent.”.

L'essai concerne le philosophe-théologien, Giles de Rome, de la fin du treizième siècle. Bien qu'il fut un disciple de Thomas d'Aquin, sa théorie de la sensualité est très différente de la sienne. Dans sa discussion de la maîtrise de soi, Giles utilise des métaphores politiques pour exprimer comment la raison contrôle les appétits des sens. Ces métaphores sont toutes d'un caractère violent. Ici, Giles se trouve en compagnie de Platon, Descartes, Kant, et plus récemment du Jésuite Karl Rahner. Aquinas, au (...) contraire, développe un modèle de contrôle de soi basé sur un langage politique de persuasion. La préoccupation centrale de l'article consiste à montrer que ces images politiques contrastées mettent en lumière des conceptions métaphysiques très différentes de la structure de la personne humaine. A cause de sa métaphysique, Giles est très proche de poser la violence dans la structure même de la personne: une position commune à l'âge moderne, mais très différente de celle de Thomas d'Aquin.

Working memory span forms an important cornerstone of current accounts of cognition, and cognitive development. We describe data that challenge the conventional interpretation of span as a measure of working memory capacity. We argue that the implications of these data undermine the analysis provided by Caplan & Waters concerning the role of working memory in sentence comprehension.

A long-standing puzzle for moral philosophers and psychologists alike is the concept of psychopathy, a personality disorder marked by tendencies to defy moral norms despite cognitive knowledge about right and wrong. Previously, discussions of the moral deficits of psychopathy have focused on willingness to harm and cheat others as well as reasoning about rule-based transgressions. Yet recent research in moral psychology has begun to more clearly define the domains of morality, en- compassing issues of harm, fairness, loyalty, authority, and spiritual (...) purity. Clinical descriptions and theories of psychopathy suggest that deficits may exist primarily in the areas of harm and fairness, although quantitative evidence is scarce. Within a broad sample of participants, we found that scores on a measure of psychopathy predicted sharply lower scores on the harm and fairness subscales of a measure of moral concern, but showed no relationship with authority, and very small relationships with ingroup and purity. On a measure of willingness to violate moral standards for money, psychopathy scores predicted greater willingness to violate moral concerns of any type. Results are further explored via potential mediators and analyses of the two factors of psychopathy. (shrink)

Using student self-reported cheating admissions and answers from a hypothetical cheating scenario, this paper analyzes the effects of individual and situational factors on potential cheating behavior. Results confirm several conclusions about student factors that are related to cheating. The probability of cheating is associated with younger students, lower GPAs, alcohol consumption, fraternity/sorority membership, and having cheated in high school. Student perceptions of the certainty and severity of punishment appear to have a negative and significant impact on the probability of cheating (...) on in-class assignments. Students who report a belief that cheating is never acceptable appear to be significantly less likely to cheat in any circumstance. This study illustrates the context-dependent nature of academic dishonesty, and the associated difficulty in understanding the relationships between measurable factors and cheating behavior.

This study identified and compared the attitudes of visitors toward zoo-housed little penguins, their enclosure and visitor experience that may influence the way visitors behave toward little penguins at two Australian zoos. Visitor attitudes were assessed using an anonymous questionnaire, targeting visitor beliefs, and experiences, where visitors were randomly approached at the penguin exhibit after they had finished viewing the penguins. Visitors were given two options to complete the questionnaire, on an iPad during their zoo visit or online (URL sent (...) via email) after their zoo visit. A total of 638 participants (495 at Melbourne Zoo and 143 at Taronga Zoo) completed the questionnaire, 42% were completed onsite during their zoo visit and 58% were completed online after their zoo visit. Most participants were living in Australia, non-zoo members, female, previously or currently owned a pet, aged between 26 and 35 years and had a University degree. Results showed that the attitude dimensions of visitors were consistent between the two zoos which indicates that these measures of attitudes were stable over time and location. Overall, visitors at both zoos had positive attitudes toward little penguins, penguin welfare, the enclosure, and visitor experience. However, whether these positive attitudes and positive visitor experience influenced the way visitors behaved toward the penguins remains unclear. There were some differences in visitor attitudes toward the perceived “aggressiveness” and “timidness” of little penguins, “negative penguin welfare”, “experience with the penguins”, “learning”, “visual barriers” and the way visitors rated their overall experience at the penguin enclosure. While the reasons for the differences in visitor attitudes and visitor experience between the zoos were not clear, some factors such as penguin behavior and enclosure design, may have been attributable to these differences. Also, a relationship was found between visitor attitudes and how visitors rated the welfare of penguins, the enclosure and visitor experience at the enclosure; more positive visitor attitudes were associated with higher ratings of penguin welfare, the enclosure and visitor experience. The practical implications of these results for zoos is unclear because the differences in visitor attitudes were numerically small. This requires further comparisons between zoos or enclosures that are more markedly different than the penguin enclosures in the present study and further research on how visitors assess zoo animals, enclosures and visitor experience.

Opinion leaders within the community may lead debate on animal welfare issues and provide a path for information to their social networks. However, little is known about OLs’ attitudes, activities conducted to express their views about animal welfare and whether they are well informed, or not, about husbandry practices in the red meat industry. This study aimed to identify OLs in the general public and among producers and compare OLs and non-OLs’ attitudes, knowledge and actions to express their views about (...) the red meat industry. Two questionnaires, one for the Australian general public and one for Australian red meat producers, were developed to identify general attitudes. From these questionnaires, OLs were identified using a two-step cluster analysis. Subsequently, a sub-sample of 19 OLs participated in a follow-up phone interview. Results disclosed some clear OLs’ characteristics. Public OLs held more negative perceptions of the red meat industry and perceived they had more knowledge about husbandry procedures. However, their actual knowledge about animal husbandry was not different from non-OLs. Public OLs also used and trusted social and internet media more than did non-OLs. In the producer group, a large percentage of OLs were identified. Producer OLs had more actual knowledge about animal husbandry and engaged in more behaviours to express dissatisfaction with the industry than non-OLs. Unlike the public respondents, this group used conventional media more than social and internet media, and their levels of trust in all kinds of media were low. While there were clear differences, both groups believed that is important to increase communication and educate about farm practices. This may present an opportunity to develop an opinion leader intervention strategy where informed OLs could later disseminate accurate information to their social networks. Further studies should test if sustained and facilitated educational sessions between public and producer OLs can assist in increasing communication, knowledge and perhaps, may assist in achieving convergence of concerns and expectations between both groups.

Surveys are used extensively in social research and, despite a lack of conclusive evidence of their ‘representativeness,’ probability internet panel surveys are being increasingly used to make inferences about knowledge, attitude and behavior in the general population regarding a range of socially relevant issues. A large-scale survey of Australian public attitudes and behavior toward the red meat industry was undertaken. Samples were obtained using a random digit dialing telephone survey and a PIP survey to examine differences between the two samples (...) regarding attitudes and behavior relating to livestock use and welfare. There was little difference in demographics between the CATI and the PANEL surveys apart from highest level of education. However, there were differences between the two samples in both attitudes and behavior toward the red meat industry after controlling for education levels. The PANEL respondents gave generally more conservative responses than did the CATI respondents in the sense that they were more positive toward the livestock industries and animal welfare within these industries. Differences were also found between the respondents of the two samples regarding behavior that relates to the red meat industry, both community and consumer behavior. PANEL respondents were less engaged in community behaviors performed in opposition of the red meat industry when compared with the CATI sample. The majority of CATI and PANEL respondents were red meat eaters and there was no difference between respondents of the two samples in relation to red meat consumption, however, there were fewer vegetarians and vegans in the PANEL survey. Possible reasons for the observed differences are discussed, however, a definitive answer will depend on further research to identify the specific psychological factors that differ between samples derived from different survey methodologies.
