The Role of Neighborhood in the Development of Aggression in Urban African American Youth: A Multilevel Analysis

The purpose of this study was to examine the role of neighborhood disadvantage and perceptions of neighborhood on the development of aggressive behavior among a sample of urban low‐income African American middle school aged youth (mean age = 11.65 years). Results of hierarchical linear modeling indicated that youth experienced significant changes in rates of aggression across the three middle school years, and that on average, negative youth perceptions of neighborhood predicted increases in aggression. Both parent and youth perceptions of neighborhood disadvantage trended toward significance as a moderator between objective neighborhood characteristics and aggression. These results are in accordance with past research, which suggests that personal evaluations of the disadvantage of a neighborhood influence child development and behavior. Future studies should examine the role that perceptions play in youth development, as well as in interventions geared towards thwarting youth aggression.     

Consumer perceptions of bundles and time‐limited promotion deals: Do contracts matter?

Marketers use various types of deals to positively influence consumers' product evaluations. Across two experiments, we manipulated print advertisements to examine whether the commonly used deal content of both bundling and time‐limited promotions affect consumers' perceived confusion, risk and value. In study 1, the influence of this content was tested in the context of a 2‐year telecommunications (telco) contract. Here, consumers associated a three‐item bundle with greater perceived value than a single item, but perceived value was reduced and risk heightened when it was only available for a limited time. We speculate that this is because of the long‐term nature of the contract. Study 2 removed the contract restriction, examining the bundling of a video game console and game(s), again with a time‐limited promotion. However, in this context, we failed to locate any interaction effects. It appears that consumers further appraise the drawbacks of a long‐term telco contract when accompanied by a time‐limited promotion and may perceive the switching costs for study 1 three‐item telco bundle to be particularly risky. Our studies represent the first empirical investigation of the effect on consumers' perceptions of offering a bundle in conjunction with a time‐limited promotion. Testing these effects in contract and no contract conditions adds to the contribution of our studies by delineating a boundary condition. From a managerial perspective, our findings are thought‐provoking in respect to information integration, or how consumers process different deal content together.

The career impact of winning an external work-related award

There is an abundance of work-related external awards in the business and corporate sectors. This study examines the impact of awards given to individuals in the business sector. Careers and signalling theory were used to initiate research in this domain with 32 interviews with winners of national work-related awards. The majority of winners were either nominated for the awards by others or encouraged to nominate by their managers, which may reflect an organisational, rather than individual, signal for distinction. Results demonstrated that all winners valued the recognition they received from their award win but in an unexpected finding, no significant career trajectory changes occurred. Award winners used their award as a signal of their excellence to distinguish themselves from others. The award gave them confidence and credibility. There was no relationship between winning an award and career success measures such as promotions or salary increases. Counterintuitive negative impacts identified by award winners are discussed.     

Magnitude of cerebral asymmetry at rest: covariation with baseline cardiovascular activity

The cerebral regulation of cardiovascular functioning varies along both a lateral and a longitudinal axis. The parasympathetic and sympathetic nervous systems are lateralized to the left and right cerebral hemispheres, respectively. Further, the frontal lobes are known to be inhibitory in nature, whereas the temporal lobes are excitatory. However, no systematic investigation has been conducted to determine the nature and strength of the relationship between the left and right frontal and temporal lobes in regulating cardiovascular activity. The present investigation sought to examine these relationships by testing the hypothesis that negative correlations would be found between baseline heart rate and blood pressure and asymmetry of alpha magnitude across the frontal lobes. Further, positive correlations were hypothesized to exist across the temporal lobes. A total of 20 women were asked to relax with their eyes closed while heart rate and blood pressure as well as quantitative electroencephalography data were obtained. The results indicated that, as hypothesized, significant negative correlations existed across the frontal lobes and significant positive correlations existed across the temporal lobes. The results provide further support for a division of responsibility between the left and right frontal and temporal lobes in the regulation of heart rate and blood pressure.     

Withholding inputs in team contexts: member composition, interaction processes, evaluation structure, and social loafing

Social loafing was observed as a naturally occurring process in project teams of students working together for 3-4 months. The authors assessed the contributions that member composition (i.e., relational dissimilarity and knowledge, skills, and abilities; KSAs), perceptions of the team's interaction processes (i.e., dispensability and the fairness of the decision-making procedures), and the team's evaluation structure (i.e., identifiability) make toward understanding loafing behavior. Identifiability moderated the impact of dispensability on loafing but not the impact of fairness on loafing. Perceptions of fairness were negatively related to the extent that participants loafed within their team. Specific aspects of relational dissimilarity were positively associated with perceptions of dispensability and negatively associated with perceptions of fairness, whereas KSAs were negatively associated with perceptions of dispensability.     

The MMPI-2 Restructured Clinical Scales: a paradigmatic shift in scale development

Tellegen et al. (2003) proposed fundamental changes in MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) scale development by discarding empirical scale development in favor of construct validation via Jackson's (1970) sequential system of scale development. As a result of their efforts, a general distress factor (Demoralization) was identified and 8 Restructured Clinical (RC) Scales were developed. Using 7,330 clinical cases from Caldwell's (1997) data set, in this study, we sought to cross-validate the MMPI-2 RC Scales. Scale homogeneity was confirmed with high alpha coefficients and interitem correlations in the expected range. We also achieved a major objective of reducing interscale correlations. In replicating Tellegen et al.'s principal components analysis, we achieved a high concordance for 6 of the 8 RC Scales. We critically examine these results in light of Jackson's construct validation. We discuss the clinical usefulness of the MMPI-2 RC Scales within the context of current and future research.     

A Challenge for Soft Line Replies to Manipulation Cases

Cases involving certain kinds of manipulation seem to challenge compatibilism about responsibility-grounding free will. To deal with such cases many compatibilists give what has become known as a ‘soft line’ reply. In this paper I present a challenge to the soft line reply. I argue that any relevant case involving manipulation—and to which a compatibilist might wish to give a soft line reply—can be transformed into one supporting a degree of moral responsibility through the addition of libertarian elements (such as alternative possibilities of a kind unavailable under determinism and executive control of the sort commonly associated with agent-causation). From a compatibilist’s perspective the subtraction of libertarian elements should make no difference to any assessment of the agent’s responsibility. The compatibilist should therefore judge the agent morally responsible after the removal of the libertarian elements. Yet removal of the libertarian elements returns the case to its original form and thus what started out as a soft line has now collapsed into a hard line reply. Various ways of resisting my argument are considered, but each is shown to carry important burdens.     

Antinatalism,Asymmetry, and an Ethic of Prima Facie Duties1

Abstract

Benatar’s central argument for antinatalism develops an asymmetry between the pain and pleasure in a potential life. I am going to present an alternative route to the antinatalist conclusion. I argue that duties require victims and that as a result there is no duty to create the pleasures contained within a prospective life but a duty not to create any of its sufferings. My argument can supplement Benatar’s, but it also enjoys some advantages: it achieves a better fit with our intuitions; it does not require us to acknowledge that life is a harm, or that a world devoid of life is a good thing; and it is easy to see why it does not have any pro-mortalist implications.     

Boosting the Potency of Resistance: Combining the Motivational Forces of Inoculation and Psychological Reactance

The efficacy of inoculation theory has been confirmed by decades of empirical research, yet optimizing its effectiveness remains a vibrant line of investigation. The present research turns to psychological reactance theory for a means of enhancing the core mechanisms of inoculation—threat and refutational preemption. Findings from a multisite study indicate reactance enhances key resistance outcomes, including: threat, anger at attack message source, negative cognitions, negative affect, anticipated threat to freedom, anticipated attack message source derogation, perceived threat to freedom, perceived attack message source derogation, and counterarguing. Most importantly, reactance‐enhanced inoculations result in lesser attitude change—the ultimate measure of resistance.     

Approximate entropy and point correlation dimension of heart rate variability in healthy subjects

The contribution of nonlinear dynamics to heart rate variability in healthy humans was examined using surrogate data analysis. Several measures of heart rate variability were used and compared. Heart rates were recorded for three hours and original data sets of 8192 R-R intervals created. For each original data set (n=34), three surrogate data sets were made by shuffling the order of the R-R intervals while retaining their linear correlations. The difference in heart rate variability between the original and surrogate data sets reflects the amount of nonlinear structure in the original data set. Heart rate variability was analyzed by two different nonlinear methods, point correlation dimension and approximate entropy. Nonlinearity, though under 10 percent, could be detected with both types of heart rate variability measures. More importantly, not only were the correlations between these measures and the standard deviation of the R-R intervals weak, the correlation among the nonlinear measures themselves was also weak (generally less than 0.6). This suggests that in addition to standard linear measures of heart rate variability, the use of multiple nonlinear measures of heart rate variability might be useful in monitoring heart rate dynamics.
