Cigarette Smoking in Same-Sex and Different-Sex Unions: The Role of Socioeconomic and Psychological Factors

Cigarette smoking has long been a target of public health intervention because it substantially contributes to morbidity and mortality. Individuals in different-sex marriages have lower smoking risk (i.e., prevalence and frequency) than different-sex cohabiters. However, little is known about the smoking risk of individuals in same-sex cohabiting unions. We compare the smoking risk of individuals in different-sex marriages, same-sex cohabiting unions, and different-sex cohabiting unions using pooled cross-sectional data from the 1997–2010 National Health Interview Surveys (N = 168,514). We further examine the role of socioeconomic status (SES) and psychological distress in the relationship between union status and smoking. Estimates from multinomial logistic regression models reveal that same-sex and different-sex cohabiters experience similar smoking risk when compared to one another, and higher smoking risk when compared to the different-sex married. Results suggest that SES and psychological distress factors cannot fully explain smoking differences between the different-sex married and same-sex and different-sex cohabiting groups. Moreover, without same-sex cohabiter’s education advantage, same-sex cohabiters would experience even greater smoking risk relative to the different-sex married. Policy recommendations to reduce smoking disparities among same-sex and different-sex cohabiters are discussed.     

Self-enhancement of Peer Acceptance: Implications for Children's Self-worth and Interpersonal Functioning

Changes in feelings of self‐worth and peer acceptance associated with self‐enhancing perceptions of their peer acceptance were examined for a normative sample and for a group of peer‐rejected children. Whether the correlates of self‐enhancement differed as a function of the way in which perceptions were assessed (i.e., general versus specific measures of self‐enhancement) or by the degree of enhancement were also studied. Using a longitudinal design, 670 students in grades 3 through 5 were assessed across an academic year. For the normative sample, general self‐enhancement of peer acceptance was associated with positive outcomes; specific self‐enhancement of peer acceptance was unrelated to changes in outcomes. Both general and specific self‐enhancement scores were associated with gains in one or more outcome measures in the rejected group. No support was found for the hypothesis that mild to moderate self‐enhancement is predictive of adjustment whereas extreme self‐enhancement is related to maladjustment.     

Using sibling data to understand the impact of family group decision-making on child welfare outcomes

Few studies have examined the impact of family group decision-making (FGDM) on child welfare outcomes. Studies in this area have often suffered from small sample sizes and lack of adequate comparison groups. Since FGDM is administered at the family level, sibling data provides an ideal way to compensate for small sample sizes and low enrollment rates in research evaluating FGDM. This study utilized sibling data from California's Title IV-E Waiver Demonstration Project Evaluation in Fresno and Riverside Counties to compare child welfare outcomes for children of families randomly assigned to receive FGDM (Fresno County, n = 110; Riverside County, n = 87) to children of families assigned to receive traditional child welfare services (Fresno County, n = 74; Riverside County, n = 52). After controlling for clustering effects using general estimating equations (GEE), group differences in child maltreatment, placement stability, and permanence were modeled using linear and logistic regression. Outcomes from both counties suggested no group differences. Though neutral outcomes on child welfare indicators may bring into question FGDM's efficacy for changing child welfare outcomes, this study confirms previous findings with smaller sample sizes on the impact of FGDM and demonstrates a methodological improvement over individual or family-case analyses.     

Convergence of non-linear functionals of smoothed empirical processes and kernel density estimates

We consider regularizations by convolution of the empirical process and study the asymptotic behaviour of non-linear functionals of this process. Using a result for the same type of non-linear functionals of the Brownian bridge, shown in a previous paper [4], and a strong approximation theorem, we prove several results for the p-deviation in estimation of the derivatives of the density. We also study the asymptotic behaviour of the number of crossings of the smoothed empirical process defined by Yukich [17] and of a modified version of the Kullback deviation.     

The prevention of child abuse

An apparent practice oriented consensus that child abuse can and should be prevented covers over considerable conflict in ideology, interest and conceptual understanding. Three current approaches to the prevention of child abuse are reviewed: clinical health led risk assessment models, broader social reform strategies and criminal justice youth victimisation models. Sources of contradiction are explored through the definitions of child abuse underpinning different strategies. The paper proposes a change in the language of child protection, away from child abuse towards specified avoidable harm. Copyright © 1999 John Wiley & Sons, Ltd.     

Detection of structurally homogeneous subsets in graphs

The analysis of complex networks is a rapidly growing topic with many applications in different domains. The analysis of large graphs is often made via unsupervised classification of vertices of the graph. Community detection is the main way to divide a large graph into smaller ones that can be studied separately. However another definition of a cluster is possible, which is based on the structural distance between vertices. This definition includes the case of community clusters but is more general in the sense that two vertices may be in the same group even if they are not connected. Methods for detecting communities in undirected graphs have been recently reviewed by Fortunato. In this paper we expand Fortunato’s work and make a review of methods and algorithms for detecting essentially structurally homogeneous subsets of vertices in binary or weighted and directed and undirected graphs.     

The Crucial Role of Nomothetic and Idiographic Conceptions of Time: Interdisciplinary Collaboration in Nuclear Waste Management

The disposal of nuclear waste involves extensive time scales. Technical experts consider up to 1 million years for the disposal of spent fuel and high‐level waste in their safety assessment. Yet nuclear waste is not only a technical but also a so‐called sociotechnical problem and, therefore, requires interdisciplinary collaboration between technical, natural, social sciences, and the humanities in its management. Given that these disciplines differ in their language, epistemics, and interests, such collaboration might be problematic. Based on evidence from cognitive psychology, we suggest that, in particular, a concept like time is presumably critical and can be understood differently. This study explores how different scientific disciplines understand extensive time scales in general and then focuses on nuclear waste. Eighteen qualitative exploratory interviews were conducted with experts for time‐related phenomena of different disciplines, among them experts working in nuclear waste management. Analyses revealed two distinct conceptions of time corresponding to idiographic and nomothetic research approaches: scientists from the humanities and social sciences tend to have a more open, undetermined conception of time, whereas natural scientists tend to focus on a more determined conception that includes some undetermined aspects. Our analyses lead to reflections on potential difficulties for interdisciplinary teams in nuclear waste management. We focus on the understanding of the safety assessment, on potential implications for communication between experts from different disciplines (e.g., between experts from the humanities and engineering for risk assessment and risk communication), and we reflect on the roles of different disciplines in nuclear waste management.     

Unraveling the Source of African American Children's Positively Biased Perceptions of Peer Acceptance

The present study investigated possible ethnic contributions to overly positive self‐perceptions in middle childhood. The goals of this study were threefold. First, the present study sought to replicate the intriguing findings reported by Zakriski and Coie that African American children overestimate their acceptance, and European American children underestimate acceptance by other‐ethnicity peers. Second, this study examined possible explanations for ethnic differences in the pattern of perceptual bias. Finally, this study extended prior research by examining ethnic differences in the accuracy of children's perceived peer acceptance. Archival data consisting of 826 children in third (N = 284), fourth (N = 241), and fifth grades (N = 301) were used in the present investigation; 237 of which were African American children, and 589 were European American children. Results of this study replicated the findings of Zakriski and Coie . Moreover, African Americans' overestimation and European Americans' underestimation of acceptance by other‐ethnicity peers was found to be attributable to more positive views of self and others among African American children relative to European American children. Finally, children were found to be more accurate about judging their acceptance by peers of the same ethnicity than those of a different ethnicity. Possible explanations of what causes African American children to have more positive views of self and others than European American children are discussed.     

“Drunkorexia”: Understanding eating and physical activity behaviors of weight conscious drinkers in a sample of college students

Objective: Behaviors of weight conscious drinkers (BWCD) include disordered eating, excessive physical activity (PA), and heavy episodic drinking. Considering that approximately 25% of the college students report BWCD, it is important to investigate what characteristics increase the likelihood of college students engaged in BWCD for both moderate and vigorous PAs. Participants: A total of 510 college students were recruited from a large, public southeastern university. Methods: Participants completed a cross-sectional survey during the spring 2015 semester. Results: Of 510 respondents, 11.2% reported moderate PA-based BWCD and 14.7% reported vigorous PA-based BWCD. Weight loss intention, BMI and Greek affiliation predicted both moderate and vigorous BWCD. Conclusions: Study findings suggest that Greek-affiliated students and students with weight loss intentions might be at an increased risk for BWCD. Along with promoting lower levels of alcohol consumption, college practitioners should consider discussing issues of weight and body image with college students as they relate to maladaptive drinking behavior.
