Competitive equilibrium with intuitionistic agents

This paper studies an economy whose agents perceive their consumption possibilities subjectively, and whose preferences are defined on what they subjectively experience, rather than on those alternatives that are objectively present. The model of agents’ perceptions is based on intuitionistic logic. Roughly, this means that agents reason constructively: a solution to a problem exists only if there is a construction by which the problem can be solved. The theorems that can be proved determine how an agent perceives a set of alternatives. A dual model relates perceived alternatives to a shared language, which the agents use in trading. So perceptions relate objective alternatives to an agent’s subjective view of them, and reporting dually relates an agent’s subjective world to a shared language. It turns out that an appropriately modified notion of competitive equilibrium always exists. However, in contrast with standard results in economic theory, competitive equilibrium need not be efficient.     

Recognizing creative leadership: Can creative idea expression negatively relate to perceptions of leadership potential?

Drawing on and extending prototype theories of creativity and leadership, we theorize that the expression of creative ideas may diminish judgments of leadership potential unless the charismatic leadership prototype is activated in the minds of social perceivers. Study 1 shows that creative idea expression is negatively related to perceptions of leadership potential in a sample of employees working in jobs that required creative problem solving. Study 2 shows that participants randomly instructed to express creative solutions during an interaction are viewed as having lower leadership potential. A third scenario study replicated this finding showing that participants attributed less leadership potential to targets expressing creative ideas, except when the “charismatic” leader prototype was activated. In sum, we show that the negative association between expressing creative ideas and leadership potential is robust and underscores an important but previously unidentified bias against selecting effective leaders.     

Seeing isn't believing: the effect of intergroup exposure on children's essentialist beliefs about ethnic categories

Adults and children seem to essentialize certain social categories. Three studies investigated whether, and how, exposure to ethnic diversity affects this bias. Participants were 516 kindergarten, 2nd grade, and 6th grade Israeli Jewish and Arab children attending regular (mono-cultural) or integrated schools. Study 1 revealed that exposure increased the salience of ethnicity, especially for Jewish children. Study 2 showed no differences among groups at kindergarten regarding the relevance of recalling a story character's ethnicity, but by 2nd grade, Jewish children attending integrated schools were the most likely to mention such information. Finally, Study 3 revealed that while all kindergarteners started off at a similar level of essentialism towards ethnicity, exposure affected Arab, but especially Jewish, children's essentialist beliefs. Moreover, there were negative correlations between the salience of and essentialism towards ethnicity. Thus, interethnic exposure alleviated children's essentialist bias towards ethnicity and did so via making children aware of, rather than blind to, ethnic categories.     

Initial validation of a measure of self-efficacy in romantic relationships

This study examines the psychometric properties of a self-report measure of self-efficacy in romantic relationships (SERR). Analyses (with 775 undergraduates) indicated a coherent factor structure representing broad beliefs about task demands in romantic relationships and abilities to meet such demands. SERR scores predict relationship anxiety and expectations of relationship success when demographic characteristics, current romantic relationship status, general self-efficacy, and social self-efficacy are considered. The SERR assesses broad feelings of relationship self-efficacy, independent of specific relationships or partners, important for understanding individual-level relationship expectations, behaviors, and interventions.

Learning from parents' stories about what works in early intervention

Using a multiple case study approach, this ethnography examined the experiences of parents of children deemed at risk for developmental delays or disabilities who had received early intervention (EI) services (birth to age 3 years) in a large urban location in Western Canada. Participants (11 adult parents and 7 children) were drawn from six families. Methods of data collection included focus groups (FG), face‐to‐face interviews and file reviews. Member check and expert reviews were conducted throughout data collection and data analyses as part of the validation process in this ethnography. Qualitative content analyses followed by thematic analyses highlighted the implementation of family‐centred practices (FCP) as a main theme. Parents identified how EI professionals using FCP embraced collaborative practices. FCP resulted in parents leading the EI process for their children. More specifically, EI professionals shared strategies and information to support parents in gaining a deeper understanding of their children's individual developmental characteristics. Parents expressed how empowering this level of understanding was for them as they learned to articulate what were their children's needs for developmental, health and educational services. Recommendations for future research include inquiring about parents' experiences for families of diverse constellations and/or residing in smaller urban or rural communities.     

Delivery of Psychological Interventions by Clinical Neuropsychologists: Current Practice in Australia and Implications for Training

Clinical neuropsychologists are increasingly involved in delivering psychological interventions to people with neurological conditions. This is a key competency for accredited Australian postgraduate neuropsychology courses; however it is not clear how effective courses are in preparing neuropsychologists to deliver interventions. The study aims were to (a) determine the frequency and confidence with which particular types of interventions are delivered by Australian neuropsychologists, (b) examine the availability of opportunities to deliver interventions on clinical placements, (c) identify barriers to delivering interventions in current workplaces; and (d) determine which factors influence the frequency and confidence with which neuropsychologists deliver interventions. An online survey was completed by 114 participants who had graduated from a postgraduate neuropsychology program. Results indicated that respondents delivered different intervention types with varying frequency. They reported limited opportunities to practice these interventions on placements. The majority wanted to be doing more interventions, with lack of time, resources, and adequate training being the major barriers. There were several significant relationships between the frequency and confidence with which respondents delivered interventions and the perceived quality of their postgraduate training. These results highlight the need to consider appropriate postgraduate training options in delivery of interventions, including increasing opportunities to practice interventions on placements.     

Generational differences in workplace behavior

Popular stereotypes suggest that generational differences among workers present challenges for workplace managers. However, existing empirical research provides mixed evidence for generational differences in important values and attitudes. The current study extends generational effects research by examining differences in actual workplace behaviors. Drawing from commonly held generational stereotypes, the authors hypothesized that Baby Boomers would exhibit (Hypothesis 1) fewer job mobility behaviors and (Hypothesis 2) more instances of compliance‐related behaviors in comparison with both GenXers and Millennials, while (Hypothesis 3) GenXers would be less likely to work overtime in comparison with Baby Boomers and Millennials. A sample of 8,040 applicants at two organizations was used to test these predictions. Results provided support for Hypothesis 1 and Hypothesis 3 and partial support for Hypothesis 2, but the effect sizes for these relationships were small. It appears the effects of generational membership on workplace behavior are not as strong as suggested by commonly held stereotypes. Implications for future research and practice are discussed.     

Understanding African American’s Religious Beliefs and Organ Donation Intentions

African Americans are overrepresented on the organ transplant waiting list and underrepresented among organ and tissue donors. One of the most highly noted reasons for lack of donation is the perception that donation is contrary to religious beliefs. The purpose of this cross-sectional study is to explore the complexities of religion (beliefs, religiosity, and religious involvement) and its association with willingness to donate and the written expression of donation intentions. Findings from a sample of 505 African American participants suggest that religion is a multidimensional construct and results differ depending on how the construct is measured and operationalized.
