Quality of College Life (QCL) of Students: Further Validation of a Measure of Well-being

This paper reports a study designed to further validate a measure of quality of college life (QCL) of university students (Sirgy, Grzeskowiak, Rahtz, Soc Indic Res 80(2), 343–360, 2007). Two studies were conducted: a replication study and an extension study. The replication study involved surveys of 10 different college campuses in different countries. The results of the replication study provided additional nomological (predictive) validation support of the measure based on a theoretical model mapping out the antecedents and consequences of satisfaction with college life. With respect to the extension study, the focus was to further test the nomological validity of the QCL measure by arguing and empirically demonstrating that the consequence of QCL is life satisfaction. The extension study involved a survey of three college campuses in different countries. The results were also supportive of the nomological validity of the QCL measure.     

Knowledge translation efforts in child and youth mental health: a systematic review

The availability of knowledge translation strategies that have been empirically studied and proven useful is a critical prerequisite to narrowing the research-to-practice gap in child and youth mental health. Through this review the authors sought to determine the current state of scientific knowledge of the effectiveness of knowledge translation approaches in child and youth mental health by conducting a systematic review of the research evidence. The findings and quality of the 12 included studies are discussed. Future work of high methodological quality that explores a broader range of knowledge translation strategies and practitioners to which they are applied and that also attends to implementation process is recommended.     

Frenzied attacks. A micro‐sociological analysis of the emotional dynamics of extreme youth violence

Inspired by phenomenological and interactionist studies of youth violence, this article offers an empirical evaluation of Collins's micro‐sociological theory of violence. The main question is whether situations of extreme violence have distinct situational dynamics. Based on analyses of 159 interactions taken from judicial case files, situations of extreme youth violence, here called frenzied attacks, were identified on the basis of the state of encapsulation of the attackers (absorbed in the violence, their sole focus is the destruction of the victim) and the disproportionateness of the violence (the attackers continue to hurt the victims even though they do not pose a threat or a challenge to them). Qualitative and statistical analyses revealed that this emotional state results from a social figuration in which the emotional balance shifts toward complete dominance of the attackers. Thus, the occurrence of frenzied attacks is associated with the moment victims hit the ground, paralyse and start to apologize, with the numerical dominance of the attackers' supportive group and with feelings of group membership, in the form of solidarity excitement and family ties in the attackers' group. Alcohol intoxication is of influence as well, but contrary to the expectation, this effect was independent from solidarity excitement. The article concludes that Collins's theory on the emotional dynamics of violence adds a new dimension to the phenomenological and interactionist traditions of research.     

State of public relations education in the United States: 2006 report on a national survey of executives and academics

A survey of 312 public relations executives and educators examined how well practitioners and instructors perceive public relations students to be prepared for the practice, the content and value of public relations curricula and, the future of public relations education in the United States. Results are largely consistent with those from a slightly smaller 1998 survey, suggesting that the views of both groups are consistent over time and providing the first two data points in what it is hoped will develop into a longitudinal line of research addressing public relations education. Judgments regarding the desired characteristics among job applicants and essential curriculum content were extremely similar between the practitioner and educator groups with both wanting more emphasis on research, ethics and strategic planning as the field moves from a low-paid technical emphasis toward a much better paid strategic planning and research emphasis.

The Effects of Authentic Leadership on Strategic Internal Communication and Employee-Organization Relationships

This study examines how strategic leadership influences excellent internal public relations by establishing the linkage between authentic leadership, symmetrical and transparent communication, and employee–organization relationships. The results showed that authentic leadership as an antecedent factor plays a critical role in nurturing an organization's symmetrical and transparent communication system, which in turn, cultivates quality employee–organization relationships. An organization's symmetrical communication worldview greatly fosters its day-to-day transparent communication practice. Transparent communication, characterized by information substantiality, accountability, and employee participation, largely contributes to employee trust, control mutuality, commitment, and satisfaction. The impact of symmetrical communication on employees' relational outcomes is fully mediated via transparent communication. Significant theoretical and practical implications of the findings are discussed.     

Comparison of asymmetric stochastic volatility models under different correlation structures

This paper conducts simulation-based comparison of several stochastic volatility models with leverage effects. Two new variants of asymmetric stochastic volatility models, which are subject to a logarithmic transformation on the squared asset returns, are proposed. The leverage effect is introduced into the model through correlation either between the innovations of the observation equation and the latent process, or between the logarithm of squared asset returns and the latent process. Suitable Markov Chain Monte Carlo algorithms are developed for parameter estimation and model comparison. Simulation results show that our proposed formulation of the leverage effect and the accompanying inference methods give rise to reasonable parameter estimates. Applications to two data sets uncover a negative correlation (which can be interpreted as a leverage effect) between the observed returns and volatilities, and a negative correlation between the logarithm of squared returns and volatilities.     

Microanalysis of 4-Month Infant Vocal Affect Qualities and Maternal Postpartum Depression

This study examined the association of 6-week maternal self-report depressive symptoms measured by the Center for Epidemiological Studies-Depression Scale (CES-D) with 4-month infant vocal affect qualities. This was part a larger study which examined many additional domains of both infant and maternal behavior. Infant vocal affect qualities were examined in 122 4-month old infants during face-to-face play in relation to 6-week maternal depressive symptoms. Mothers were categorized depressed (26.2%) based on a 16+ cutoff on the CES-D. Videotaped interactions were coded on a 1-s time basis for infant vocal affect qualities (high positive, neutral/positive, fuss/whimper, cry, angry protest and silent.) Infants of depressed mothers were more vocally activated in both positive and negative qualities. In addition, infants of depressed mothers were more vocally variable, specifically in and out of fuss/whimper, as well as more likely to change, rather than maintain vocal states.
