A general equadion is presented, covering all arbitrary values for the true population splits, for obtaining the true population phi, given observed cell frequencies for a selected sample, and true population splits. A nongeneral solution is also offered, based on the use of the G Index. Demonstrations with hypothetical data are given.     

Theology, History, and Religious Identification: Hegelian Methods in the Study of Religion

This essay deals with the impact of Hegel's philosophy of religion by examining his positions on religious identity and on the relationship between theology and history. I argue that his criterion for religious identity was socio-historical, and that his philosophical theology was historical rather than normative. These positions help explain some historical peculiarities regarding the effect of his philosophy of religion. Of particular concern is that although Hegel’s own aims were apologetic, his major influence on religious thought was in the development of various historical and critical approaches to religion.     

Early Adolescent Growth in Depression and Conduct Problem Symptoms as Predictors of Later Substance Use Impairment

Most studies of adolescent substance use and psychological comorbidity have examined the contributions of conduct problems and depressive symptoms measured only at particular points-in-time. Yet, during adolescence, risk factors such as conduct problems and depression exist within a developmental context, and vary over time. Though internalizing and comorbid pathways to substance use have been theorized (Hussong et al. Psychology of Addictive Behaviors 25:390-404, 2011), the degree to which developmental increases in depressive symptoms and conduct problems elevate risk for substance use impairment among adolescents, in either an additive or potentially a synergistic fashion, is unclear. Using a school-based sample of 521 adolescents, we tested additive and synergistic influences of changes in depressive symptoms and conduct problems from 6th to 9th grade using parallel process growth curve modeling with latent interactions in the prediction of late adolescent (12th grade) substance use impairment, while examining gender as a moderator. We found that the interaction between growth in depression and conduct disorder symptoms uniquely predicted later substance use problems, in addition to main effects of each, across boys and girls. Results indicated that adolescents whose parents reported increases in both depression and conduct disorder symptoms from 6th to 9th grade reported the most substance use-related impairment in 12th grade. The current study demonstrates that patterns of depression and conduct problems (e.g., growth vs. decreasing) are likely more important than the static levels at any particular point-in-time in relation to substance use risk.     

The Effects of Need for Cognition and Need for Affect on Partisan Evaluations

The voting behavior literature has advanced two prominent theoretical models of partisanship: the social psychological and rational models. Implicit to both stylized models is the assumption that all partisans process information similarly. Yet, growing research in psychology suggests that individuals possess different motivations when evaluating information. We propose that the applicability of the stylized models of partisanship is conditioned on individuals' need for cognition (NFC) and need for affect (NFA), with the social psychological model being most applicable to individuals who have a high NFA and the rational model most applicable to those with a high NFC. To test this proposition, we fielded a survey in which respondents who identified with the two major political parties in the United States (Democrat or Republican) were randomly assigned factual information that depicted either their party or their opposing party in a negative light. Respondents were then asked to assess the actions of that party and subsequently evaluate both political parties. We find evidence that is generally consistent with the proposition that the stylized models of partisanship are conditionally dependent on the extent to which individuals possess a need to engage in effortful thinking or a need to seek out emotions.     

Descriptive and Predictive Analyses of Industrial Buyers' Use of Online Information for Purchasing

The impact of demographic differences between sales reps and their managers is explored using data gathered from 340 manager-rep dyads. Education and gender differences between sales reps and managers, but not age differences, are shown to affect sales reps' role stress, organizational attachment, and perceptions of opportunities for advancement, as well as managers' ratings of the reps' performance. Study results support findings of previous research addressing relational demography and the similarity-attraction paradigm. The chief divergence of this study is that it depicts the role of frequency of contact between sales rep and manager in the link between demographic similarity and several outcome variables.     

The interplay of received social support and self-regulatory factors in smoking cessation

Objective: In smoking cessation, individual self-regulation and social support have both proven to be useful. However, the roles of self-regulatory processes and social support are mostly examined separately. The present study aims at examining the unique and joint interactive effects of self-regulation as specified in the health action process approach (HAPA) and social support on smoking cessation. The study tested whether social support can compensate for low levels of self-regulation or whether synergistic effects emerge.

Design & Measures: Around a self-set quit date, 99 smokers completed baseline questionnaires on HAPA-variables, smoking-specific received social support and smoking cessation (continuous abstinence and point prevalence), with a follow-up Cpproximately 29?days after the quitdate.

Results: Social support moderated the association between volitional self-efficacy and smoking, as well as coping planning and smoking but not between action planning and smoking. No compensatory effect of social support for lower levels of individual regulation emerged but the combination of high levels of the individual variables and social support was related to successful smoking cessation, indicating a synergistic effect.

Conclusions: The results confirm the importance of examining both self-regulation and social factors in smoking cessation. This should be considered when developing future interventions for smoking cessation.     

Functional neuroimaging of working memory in survivors of childhood brain tumors and healthy children: Associations with coping and psychosocial outcomes

Purpose: Pediatric brain tumors are the second most common cancer diagnosis in individuals under age 20 and research has documented significant neurocognitive, psychosocial, and emotional late effects. Associations among these deficits have not been adequately considered and the role of survivors’ coping with stress in relation to deficits is unknown. Further, research has yet to examine neurobiological processes related to neurocognitive, psychosocial, and emotional difficulties in survivors through the use of functional neuroimaging. Method: Questionnaire measures and functional neuroimaging were used to examine the neurocognitive, psychosocial, and emotional functioning and coping responses of survivors of pediatric brain tumors (N = 17; age 8–16) and healthy children (N = 15). Results: Survivors experienced elevated levels of psychosocial and behavioral/emotional difficulties relative to healthy controls and normative data. Increases in brain activation in prefrontal and other anterior regions in response to a working memory task were associated with better psychosocial functioning, use of engagement coping strategies, and less use of disengagement coping strategies. Regression analyses suggest coping accounts for a significant portion of the association between brain activation and behavioral/emotional functioning. Conclusions: This study extends late-effects research by examining neurobiological processes associated with psychosocial and emotional difficulties. These findings contribute to our understanding of difficulties in survivors and provide a foundation for research exploring these associations and mediators of deficits in future longitudinal studies.     

Stemming the tide: Predicting women engineers' intentions to leave

This investigation adapts and extends the Social Cognitive Career Theory (SCCT) by integrating it with central constructs from turnover theory. The extended model proposes that domain specific self-efficacy and outcome expectations predict job satisfaction and organizational commitment — the two key job attitudes that have been established as influential predictors of turnover cognitions and behaviors. Further, we proposed that one form of organizational supports, specifically developmental opportunities at work, are sources of self efficacy and outcome expectations, and that the relationship between organizational supports and job attitudes is mediated by self-efficacy and outcome expectations. The proposed model was tested on a national sample of 2,042 women engineers. Overall, the results provided support for our newly developed model. Implications for theory, research, and practice are discussed.     

Expertise differences in a video decision-making task: Speed influences on performance

Video clips of different speeds were used in a simulation of decision-making in Australian football to test the effects on decision accuracy and decision time. Elite and sub-elite and novice Australian footballers watched videos in six speeds (0.75, 1.0, 1.25, 1.5, 1.75 and 2.0 times normal speed). Participants responded by using a mouse-click to indicate where they would pass the ball for that particular video clip. The elite and sub-elite groups also rated each clip for how ‘game-like’ the decision-making felt. The elite group was significantly more accurate than the sub-elite and novice groups, and the sub-elite group was more accurate than the novice group. Within-speed analysis showed the elite group excelled at the faster video speeds. The use of speeded video delineated clear expertise differences between the groups at the 1.5 speed. Elite and sub-elite players identified the 1.25 and 1.5 speeds as most ‘game-like’ for decision-making. These results show that athletes perceive moderately speeded video as more game-like. Speeded video is further speculated to have allowed elite athletes to perform more automatically, with a faster processing efficacy, a key characteristic of elite performance. This study suggests the use of speeded video as a potential new research paradigm to explore expertise and a viable method for future training interventions for decision-making.
