Individual and ecological assets and positive developmental trajectories among gang and community-based organization youth

The Search Institute framework for conceptualizing developmental assets was used in a longitudinal study of African American male youth involved in gangs or in community-based organizations (CBOs) serving youth. Analyses of intraindividual change indicated that individual and ecological assets are linked to positive developmental trajectories among these youth.     

Producing More with Less? Community Forestry in Durango,Mexico in an Era of Trade Liberalization*

Abstract Through a qualitative case study of peasant‐organized forestry in Durango, Mexico, this paper examines how neoliberal policy reform is reshaping the community forestry sector. Post‐1992 agrarian and forestry laws facilitate the emergence of new forms of association in ejidos (collective property communities created by agrarian reform) and agrarian communities, and reorganize the delivery of forestry technical services. These developments indirectly undermine peasants' capacity to deal with the sector's long‐standing internal problems, putting at risk their ability to provide themselves with the services they need for sustainable community livelihoods and forest exploitation. Nevertheless, this study of a forest peasant federation shows that institutional change is a process peopled by groups of social agents who respond creatively to external structure from local organizational and community contexts. Ethnographic methods can be used fruitfully to study complex interactions between multiple levels of political‐economic structure and local action, which both constrain and provide opportunities for the organization of common‐pool resource management regimes.     

An examination of relationships between children's protective services social worker assessment of risk and independent LONGSCAN measures of risk constructs

Risk assessment as a Child Protective Services (CPS) decision-making model has been implemented in the field since the late 1980s. Research activities on risk assessment have included comparative analyses, prioritization, classification studies, implementation, and cultural sensitivity analyses. In the last decade, the major research focus has been on studies related to predictive validity. Little research on risk assessment has focused on other types of construct validity, including convergent validity. Using data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) and CPS investigation records, this study examined the correlations between CPS workers' ratings of risk on nine risk factors and independent measures of the same risk constructs collected by research interviewers. The data indicate significant correlations with caregiver risk factors such as physical/mental/emotional impairment, however there is little correlation with child risk factors associated with developmental or behavioral issues, or socio-economic factors such as stress and social support. Implications of the findings for policy and practice are discussed.     

Coerced Sexual Experiences Among Adolescent Substance Abusers: A Potential Pathway to Increased Vulnerability to HIV Exposure

This study describes the forced sexual experiences, serious internalizing problems, risky sexual behavior, and alcohol-related correlates of risky sexual behavior of 120 substance abusing adolescents and young adults (87 men, 33 women; mean age = 17.2 years) undergoing treatment. Prior coerced sexual experiences were associated with suicidal thoughts and attempts, higher levels of risky sexual behaviors, avoidance motives for drinking, and sexual decision-making conducive to risky sexual behavior. Sexual coercion was associated with patterns of sexual behavior and alcohol use that potentially increase vulnerability to HIV exposure. Social workers can play a number of significant roles in addressing ongoing psychological distress associated with sexual coercion among these predominantly female adolescents. Therefore, effective social work practice should enhance treatment effectiveness and reduce risk for a range of maladaptive outcomes including exposure to sexually transmitted diseases (STDs) and revictimization.     

INFORMATIONAL INTIMACY AND FUTURISTIC FLU: LOVE AND CONFUSION IN THE MATRIX

Cyberpunk's influence upon our understanding of the information revolution is indicated by the fact that its seminal novel, Neuromancer (Gibson 1984), is accredited with the coining of the now widespread non-fictional concept of cyberspace. Beyond providing this resonant concept, however,some of the genre's more recent work known as biopunk is shown to provide fresh insights into the cultural experience of a society increasingly transformed, not only by the extent of technological change in a new informational age, but also its unprecedented pace. This paper reviews cyberpunk to demonstrate the vivid ways in which it uses its fictional licence to catalogue and articulate imaginatively a profoundly ambivalent aspect of contemporary culture in the age of information. We find ourselves interacting more and more closely and rapidly with information, yet at the same time, we feel increasingly run down by the effort demanded of such close and rapid interaction: hence the title-phrases, informational intimacy and futuristic flu. Numerous examples are provided of cyberpunk'szeitgeist-capturing qualities in the face of a profound and rapid information-induced paradigm shift. A mismatch is shown to exist between the conceptual categories we have at our disposal and the qualitatively new scenarios created by the latest information technologies. This paper argues, however, that assuming one maintains a healthy sense of its various deliberate ironies, cyberpunk's fictional exaggerations are seen as potentially instructive elements for a society striving to avoid a bout of techno-influenza.     

A multivariate von mises distribution with applications to bioinformatics

Motivated by problems of modelling torsional angles in molecules, Singh, Hnizdo & Demchuk (2002) proposed a bivariate circular model which is a natural torus analogue of the bivariate normal distribution and a natural extension of the univariate von Mises distribution to the bivariate case. The authors present here a multivariate extension of the bivariate model of Singh, Hnizdo & Demchuk (2002). They study the conditional distributions and investigate the shapes of marginal distributions for a special case. The methods of moments and pseudo‐likelihood are considered for the estimation of parameters of the new distribution. The authors investigate the efficiency of the pseudo‐likelihood approach in three dimensions. They illustrate their methods with protein data of conformational angles     

A marginal regression model for multivariate failure time data with a surviving fraction

A marginal regression approach for correlated censored survival data has become a widely used statistical method. Examples of this approach in survival analysis include from the early work by Wei et al. (J Am Stat Assoc 84:1065–1073, 1989) to more recent work by Spiekerman and Lin (J Am Stat Assoc 93:1164–1175, 1998). This approach is particularly useful if a covariate’s population average effect is of primary interest and the correlation structure is not of interest or cannot be appropriately specified due to lack of sufficient information. In this paper, we consider a semiparametric marginal proportional hazard mixture cure model for clustered survival data with a surviving or “cure” fraction. Unlike the clustered data in previous work, the latent binary cure statuses of patients in one cluster tend to be correlated in addition to the possible correlated failure times among the patients in the cluster who are not cured. The complexity of specifying appropriate correlation structures for the data becomes even worse if the potential correlation between cure statuses and the failure times in the cluster has to be considered, and thus a marginal regression approach is particularly attractive. We formulate a semiparametric marginal proportional hazards mixture cure model. Estimates are obtained using an EM algorithm and expressions for the variance–covariance are derived using sandwich estimators. Simulation studies are conducted to assess finite sample properties of the proposed model. The marginal model is applied to a multi-institutional study of local recurrences of tonsil cancer patients who received radiation therapy. It reveals new findings that are not available from previous analyses of this study that ignored the potential correlation between patients within the same institution.     

Rapid growth or stagnation: An economic policy choice

Why has the American economy performed so poorly in the past decade, especially in comparison with the two prior decades? This paper makes the theoretical and empirical case that a series of economic policy decisions provides the most satisfactory explanation and that policy reform will restore good economic performance. The paper also considers alternative explanations including the idea of a new secular stagnation unrelated to policy and the view that the deep financial crisis inevitably delayed recovery from the recession.     

Self‐Destructive Symptomatic Frames in Clinical Adolescents: Is the Same Different?

This study examines individual and family predictors of different self‐destructive patterns—only suicidal ideation, only nonsuicidal self‐injury (NSSI), or suicide attempts (that may also include both suicide ideation (SI) and NSSI)—in a sample of outpatient adolescents (N = 42; 86% females) with mean age of 16 years (SD = 1.86). Results indicated that there are differences in youngsters with self‐destructive behaviors in their perception of paternal rejection and maternal control, when compared with youngsters reporting only SI. Adolescents from the groups with self‐destructive behaviors differ only in age. Together, these data highlight the relevance of adopting an ecosystemic perspective, which includes both the patients and their families, regarding treatment and prevention of self‐destructive symptomatic frames.
