Anger Expression Mode,Depressive Symptoms,Hopelessness, and Decision Coping among African American Adolescents

This study examined the relationship between anger expression mode, depressive symptoms, hopelessness, and decision coping patterns among a non-clinical community sample of 276 low-income African American adolescents (mean age = 14.47). Participants were students in sixth through tenth grades enrolled in health and wellness classes in two public schools in West Tennessee. They were asked to complete a battery of instruments including the Anger Style Inventory, Children's Depression Inventory, Hopelessness Scale for Children, and Flinders Adolescent Decision Making Questionnaire. Findings indicate a significant association between anger expression mode, depressive symptomatology, hopelessness, and decision coping pattern among study participants. Gender and screening positive for depressive symptoms predicted participant's anger response mode. Using multiple assessment scales may provide useful information toward preventing the onset of clinically significant emotional disorders among adolescents.     

Entertainers or education researchers? The challenges associated with presenting while black

How black faculty experience presenting their research in educational venues within the context of historical objectification of black people as sources of entertainment is an underexplored topic in higher education research. Presenting research has far-reaching implications for black academics’ advancement, such as future employment and opportunities for research collaboration. Thus, how black faculty are perceived while presenting has significant implications for their career trajectories. This study is concerned with understanding how black higher education faculty perceive, interpret, and respond to how they are perceived while presenting within a context of racialized academic scrutiny. Thirty-three black professors were interviewed about their participation in a number of presentation contexts, including national conferences, symposia, and campus job talks. Study participants discussed encountering multiple layers of racial stereotyping and bias, and also how their keen racial awareness enabled them to develop strategic coping mechanisms to manage audience reactions. These strategies also represented the self-sacrifices they made that altered their racial identities. By examining black faculty members’ struggles to be valued personally and professionally in white-dominated academic sites, the study findings can enrich critical interpretations of racism in higher education.

Unlocking the mask: a look at the process by which authentic leaders impact follower attitudes and behaviors

The conceptual and empirical links between authentic leadership and follower attitudes, behaviors, and performance outcomes have not been fully developed. Although we have a number of articles developing the theory of authentic leadership and testing propositions that will appear in a forthcoming special issue of The Leadership Quarterly (Vol. 16, Issue 3, 2005), the focus of this article is to provide some of the initial foundation work for the broader theoretical framework of how authentic leaders influence follower attitudes, behaviors, and performance. Here, we draw from positive organizational behavior, trust, hope, emotion, identification, and identity theories to describe the processes by which authentic leaders exert their influence on followers' attitudes and behaviors. Research propositions based on the proposed theoretical model and implications for future theory building and research are presented.     

Teaching Note—Implementation of Online Client Simulation to Train and Assess Screening and Brief Intervention Skills

Given the workforce shortage of adequately trained behavioral health professionals, schools of social work are ideally positioned to teach empirically supported treatments for preventing and reducing substance use, specifically, screening and brief interventions. Traditionally, opportunities to practice screening and brief intervention skills occur in classes and field placements; however, these opportunities are limited by class time, placement setting, and multiple demands placed on field instructors. Online client simulation has potential to address these limitations as an asynchronous training and assessment tool. This article details the integration of online interactive client simulation technology in advanced-level master of social work curricula. Drawing on longitudinal pre- and postdata, we present a preliminary analysis of changes in students’ screening and brief intervention skills.     

Life table estimator revisited

We explore the standard life table (actuarial) estimator for grouped right-censored survival data and its extensions in order to consider its relationship with the Kaplan–Meier estimator, and to investigate the critical properties of the extended life table estimators (ELTEs). We discuss certain conditions for the ELTE to be consistent and develop a characterization of the standard life table estimator using the consistency property under any choice of at least two observation times of a finite interval. We also perform a comparative analysis of the ELTEs with the corresponding maximum likelihood estimators for grouped right-censored survival data.     

Child Sexual Abuse and Intimate Partner Violence Victimization in Adulthood: Sex-Differences in the Mediating Influence of Age of Sexual Initiation

Child sexual abuse is a major public health concern in the United States with devastating sequelae. Although the relationship between child sexual abuse and intimate partner violence victimization in adulthood is known, little is known about the mediating influence of the age of sexual initiation on the association, or whether sex differences exist. Using data from waves I, III, and IV of the National Longitudinal Study of Adolescent to Adult Health (N = 1,163), we aimed to examine the mediating influence of age of sexual initiation on the association between child sexual abuse and intimate partner violence victimization in adulthood and identify sex differences. Findings reveal that in female survivors, age of sexual initiation partially mediated the association between child sexual abuse and physical intimate partner violence victimization in adulthood. In male survivors, no mediational effect was observed. Public health practitioners should be aware of sex differences in the effect of early sexual initiation on intimate partner violence victimization in adulthood among child sexual abuse survivors.

Expert Knowledge Elicitation: Subjective but Scientific

ABSTRACT

Expert opinion and judgment enter into the practice of statistical inference and decision-making in numerous ways. Indeed, there is essentially no aspect of scientific investigation in which judgment is not required. Judgment is necessarily subjective, but should be made as carefully, as objectively, and as scientifically as possible.

Elicitation of expert knowledge concerning an uncertain quantity expresses that knowledge in the form of a (subjective) probability distribution for the quantity. Such distributions play an important role in statistical inference (for example as prior distributions in a Bayesian analysis) and in evidence-based decision-making (for example as expressions of uncertainty regarding inputs to a decision model). This article sets out a number of practices through which elicitation can be made as rigorous and scientific as possible.

One such practice is to follow a recognized protocol that is designed to address and minimize the cognitive biases that experts are prone to when making probabilistic judgments. We review the leading protocols in the field, and contrast their different approaches to dealing with these biases through the medium of a detailed case study employing the SHELF protocol.

The article ends with discussion of how to elicit a joint probability distribution for multiple uncertain quantities, which is a challenge for all the leading protocols. Supplementary materials for this article are available online.     

Difficult Conversations in a School of Social Work: Exploring Student and Faculty Perceptions

Difficult conversations about isms, power, privilege, and oppression are an essential part of social work education, and they present unique challenges for students and faculty. The current study examined students’ and faculty’s perceptions of the safety of the classroom and the competence of the faculty in facilitating difficult conversations at a graduate school of social work in New York City. Student and faculty versions of a survey were distributed to both groups. Results indicated students rated the experience of having difficult conversations at the school significantly more negatively than the faculty did. The majority of respondents expressed the need for courses and training to be more fluent in having difficult conversations. Future directions are discussed based on the findings.
