Anti-foundation and self-reference

This note argues against Barwise and Etchemendy's claim that their semantics for self-reference requires use of Aczel's anti-foundational set theory, AFA, and that any alternative would involve us in complexities of considerable magnitude, ones irrelevant to the task at hand (The Liar, p. 35).Switching from ZF to AFA neither adds nor precludes any isomorphism types of sets. So it makes no difference to ordinary mathematics. I argue against the author's claim that a certain kind of naturalness nevertheless makes AFA preferable to ZF for their purposes. I cast their semantics in a natural, isomorphism invariant form with self-reference as a fixed point property for propositional operators. Independent of the particulars of any set theory, this form is somewhat simpler than theirs and easier to adapt to other theories of self-reference.I thank John Mayberry for discussions of axiomatics which inspired this paper. Jon Barwise's criticism of an earlier draft improved this one as did an anonymous referee.     

Confidentiality Limits With Clients Who Have HIV: A Review of Ethical and Legal Guidelines and Professional Policies

The publication of the first counseling articles addressing confidentiality limits of clients who have HIV (human immunodeficiency virus) and continue to be sexually active with an uninformed partner occurred 4 years ago. Since that time, dialogue about whether a helping professional may ethically and legally breach confidentiality has not resolved the dilemma but instead has created more questions and controversy for counselors. In this article the authors highlight the barrage of ethical issues regarding HIV and Acquired Immune Deficiency Syndrome (AlDS), review ethical and legal guidelines pertaining to HIV and AIDS and confidentiality, summarize HIV and AIDS confidentiality policies of the major helping professional organizations, articulate questions that contribute to the confidentiality dilemmas, and challenge the American Counseling Association (ACA), formerly the American Association for Counseling and Development (AACD), to develop specific guidelines for counselors.     

Sexual behaviour,condom use and prediction in attenders at sexually transmitted disease clinics—implications for counselling

A cohort of 260 clinic attenders completed an inventory to examine sexual behaviour, condom use and appraisal and to determine whether situational factors in their last sexual encounters were predictive of condom use. Response to health education compaigns promoting condoms in the light of HIV were also examined. It was found that risk exposure was consistently high. A subsample induldged in anal intercourse, which was unprotected in over two-thirds of instances. Condom uptake was varied Difficulties with condoms were widespread and fell into physical and psychological categories. The only predictor of condom use was the desire for unprotected sex. This data seems to indicate that sex is not a drive out of conscious control, but that individuals weigh up costs and benefits which may be marginally influenced by some situational variables such as alcohol. This has profound implications for counselling which can be aimed at addressing the misconceptions and beliefs that some individuals hold. Such misconceptions may result in risky behaviour which may potentially expose them to HIV. Such understanding is an important prerequisite for effective interventions. Differences between responses for heterosexual and homosexual men and women were examined.     

Biased cognitive operations in anxiety: Accessibility of information or assignment of processing priorities?

There is considerable evidence that anxiety is associated with a cognitive bias favouring the processing of threat-related information. Bower's (1981) network model attributes this bias to the enhanced availability of mood congruent information from memory. However, certain experimental tasks do not reveal such a bias, when this effect is strongly predicted by the model. We note that all tasks which have demonstrated such mood congruent processing effects in anxious subjects share the requirement that these subjects must assign priorities to simultaneously available, and differentially valenced, alternative processing options. This feature has been consistently lacking in those paradigms we have found insensitive to the influence of anxiety. It is therefore suggested that anxiety is associated with the assignment of high processing priorities to threat-related options, rather than with the facilitated availability of threat-related information from memory. This proposal was experimentally tested using a lexical decision task, which is sensitive to the accessibility of information from memory, under conditions which either do or do not introduce the requirement to assign priorities to alternative processing options. The results indicate that the facilitated processing of threat related stimulus words, shown by generalised anxiety patients, does indeed appear to reflect a bias in the assignment of processing priorities, rather than the enhanced availability of this information from memory.     

The influence of personal and public health and smart applications on biking behavior in South Korea

Bicycling is an important form of active transport that contributes to sustainability mobility as a result of its role in personal and public health and emissions reduction. The significance of which has grown since the COVID-19 pandemic outbreak. However, biking studies have neglected, in theoretical terms, developing an understanding of why consumers bike. Therefore, this research designs and verifies an extended theory of planned behavior adding personal and public health and a moderator of perceived smart application usage to help explain such consumer behavior. This study is based on a digital survey of South Koreans who biked for leisure, tourism, and/or work, utilizing partial least squares-structural equation modeling with multi-group analysis and Fuzzy-set Qualitative Comparative Analysis. Results revealed that personal health is most important to cyclists, followed by public health, attitude, and subjective norm. Interestingly, people with perceived high usage of smart applications for biking show stronger relationships between public health and attitude and perceived behavioral control and behavioral intention than low users. In contrast, individuals with perceived low usage of smart applications for biking reveal a stronger relationship between attitude and behavioral intention than high users. The high and low user groups of smart applications also distinctively differ in levels of cycling behavior. Consequently, this work offers several theoretical and managerial implications for research and practice.     

Social contact,own-group recognition bias and visual attention to faces

The own-group recognition bias (OGRB) has been consistently linked to social contact in theoretical accounts. Indeed, social contact is assumed by most authors to underlie the perceptual expertise of out-groups' faces. However, little is known empirically about how it might impact face-processing strategies. We tested the proposition that social interaction would improve the face recognition performance of another group by modulating visual strategies for different face areas. In Experiment 1, we studied visual processes using an eye tracker during a person's first live encounter with a particular member of their own group (European) or an outgroup (African) to explore how increasing familiarity during a first interaction influences face-processing strategies. In Experiments 2 and 3, we explored the effect of simulated intergroup contact on face recognition accuracy, while simultaneously studying the impact of contact on visual attention strategies that occur during recognition (Experiment 2) and encoding (Experiment 3). The results showed a strong OGRB and a difference in visual processes based on the ethnic group of the targets. Although a single interaction is not sufficient to reduce the OGRB, familiarization during a live interaction (Experiment 1) and virtual social contact (Experiment 2) had an impact on the visual strategies employed.     

Affectionate communication,health, and relationships

A robust body of research attests to the mental and physical health correlates and consequences of affectionate communication. Like much research on personal relationships, however, this work may overrepresent certain portions of the population, may underrepresent others, and may not effectively account for intersections of identities. We define intersectionality as comprising the unique effects of two or more social identities interacting with each other. To assess this literature with an eye toward intersectionality and representation, the present article reports a systematic review of 86 individual empirical studies representing 26,013 participants. The review concludes that there is no explicit or implicit attention to intersectionality in the existing research on affectionate communication and health, and that U.S. Americans, women, younger individuals, white individuals, and students are overrepresented in research samples. The review ends with future directions to encourage more inclusive research on this topic.     

Group membership and everyday social comparison experiences

In two everyday experience studies, we examined the degree to which everyday social comparisons are framed by group membership. In the first study, 30 undergraduates attending a public university in the United States completed short questionnaires about their social comparison experiences whenever they were signalled. In the second study, 34 ethnic minority undergraduates from the same university completed similar questionnaires about their social comparison experiences. Across both studies, comparisons in which participants viewed themselves as an ingroup member in comparison to an outgroup comprised less than 10% of the comparison experiences reported by participants. However, minorities in the second study who reported closer identification with their ethnic group reported more comparison experiences in which they mentioned their own or the comparison target's ethnicity.
