Modeling Nonlinear Change via Latent Change and Latent Acceleration Frameworks: Examining Velocity and Acceleration of Growth Trajectories

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.     

How many notions of necessity?

Evans distinguishes between superficial necessity and deep necessity in his analysis of the contingent a priori. The distinction between these two notions of necessity is formalized by Davies and Humberstone through the addition of the operator Fixedly to Actuality Modal Logic (AML, S5A), where deep necessity is represented by the combination Fixedly Actually. Wehmeier’s Subjunctive Modal Logic (SML) provides an extension of the expressive capacity of ordinary modal predicate logic alternative to AML. I add Fixedly to SML and show that in the system SML with Fixedly the distinction between deep and superficial necessity disappears. I conclude that the existence of the distinction between deep and superficial necessity, as well as the existence of the contingent a priori, cannot be asserted independently of the choice of background logic.     

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.     

Adolescent intelligence and socio-economic wealth independently predict adult marital and reproductive behavior

Counter-intuitively, sociobiological and evolutionary theories predict a negative relationship between g and reproduction when applied to modern humans. Although existing research has documented this dysgenic trend, the association between g and socio-economic factors presents a confound that has not systematically been addressed in prior research. Based on a sample of 325,252 individuals drawn from the nationally representative Project Talent database, we examined the unique effects of g and socio-economic wealth, assessed in adolescence, on marital and reproductive behavior over the next 11 years. Results show that both g and socio-economic wealth have unique, independent negative effects on marital and reproductive behavior such that individuals of higher intelligence and higher wealth delay marriage and reproductive longer than those of lower intelligence and wealth. The effect of g was slightly stronger than that of wealth, though for both variables much of their influence was mediated by educational attainment. Consistent with sociobiological theory, these dysgenic effects were stronger among females than males.     

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.     

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.     

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.     

Marketing social norms: Social marketing and the ‘social norm approach’

This paper is inspired by the observation that the social norm approach (SNA) to socially desirable behaviour change – that is, telling people about what lots of other people do – retains something of a Cinderella role among social marketing practitioners and academics. Thus, the objective of this paper is to bring the social norm approach to the attention of a wider – and specifically, marketing and social marketing – audience, in the hope that the practice, study and critical analysis of the approach can be widened and deepened. We begin this task by tracing the background of the social norm approach to its origins in psychology and social psychology and by discussing a number of typical social norm campaigns. Thereafter, we review four key characteristics of successful social norm campaigns. In our discussion, we return to a more theoretical discussion of how the social norm approach works, and we pose a number of questions that emerge from the paper.
