Promoting Resilience Through Social Work Practice with Groups: Implications for the Practice and Field Curricula

The realities of contemporary social work practice often push social workers toward a deficit-focused orientation. The article begins with an overview of the major tenets of resiliency and adversarial growth theories and related research findings. We suggest that the group modality epitomizes the application of resiliency theory and adversarial growth to social work practice. A primary focus of this article is on articulating and illustrating the unique contribution group work makes for promoting client resilience. The article provides a theoretical and empirical framework that students, practitioners, and educators alike can use to identify, understand, and capitalize on client strengths through group work. Implications for social work education, specifically the practice and field curricula, are discussed.     

Rural versus urban residence as an influence on grandparent caregivers’ needs for service

The present study explored the impact of rural (n = 26) versus urban (n = 49) environments on perceived needs for services among grandparent caregivers, wherein persons participated in focus groups targeting their needs and concerns and/or completed a mailed survey. While findings suggested substantial similarity across rural and urban persons in unmet needs, areas of difficulty, and service barriers, rural grandparents who reported their health to be fair or poor reported the greatest unmet needs and experienced the widest array of problem areas, while the opposite was true for urban grandparent caregivers. With few exceptions, sociodemographic factors failed to predict unmet needs, array of problem areas, and barriers. The practice and policy implications of these findings are discussed.     

Is Hypersexuality Dimensional or Categorical? Evidence From Male and Female College Samples

The recent attempt to introduce hypersexual disorder into the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), has increased empirical scrutiny of the construct. Consensus on its definition and underlying structure remains elusive. Whereas some conceptualizations favor a categorical latent structure, others speculate that hypersexual behavior is dimensional. Research on the latent structure of hypersexual behavior, however, has been sparse. This is unfortunate, because determination of the latent structure can contribute to more accurate assessment, diagnosis, and understanding of etiological process. To date the only study on hypersexuality's latent structure found consistent evidence of a dimensional structure for males but less clear results for females. In the present study the Multidimensional Inventory of Development, Sex, and Aggression (MIDSA), a self-report, contingency-based inventory, was administered to 1,146 college students. Four indices of hypersexual behavior and six indices of sexual compulsivity were analyzed, using three taxometric methods (mean above minus below a cut [MAMBAC], maximum covariance [MAXCOV], and latent mode factor analysis [L-Mode]). Evidence supported a dimensional latent structure for hypersexuality in male and female samples. Future assessments of hypersexuality must focus on adequate reliability and discriminant validity across the continuum of sexual behavior rather than on attempts to differentiate between arbitrarily developed diagnostic categorizations.     

Psychosocial safety climate as an antecedent of work characteristics and psychological strain: A multilevel model

Abstract

Psychosocial safety climate (PSC) refers to a specific organizational climate for the psychological health of workers. It is largely determined by management and at low levels is proposed as a latent pathogen for psychosocial risk factors and psychological strain. Using an extended Job Demands-Control-Support framework, we predicted the (24 month) cross-level effects of PSC on psychological strain via work conditions. We used a novel design whereby data from two unrelated samples of nurses working in remote areas were used across time (N=202, Time 1; N=163, Time 2), matched at the work unit level (N= 48). Using hierarchical linear modelling we found that unit PSC assessed by nurses predicted work conditions (workload, control, supervisor support) and psychological strain in different nurses in the same work unit 24 months later. There was evidence that the between-group relationship between unit PSC and psychological strain was mediated via Time 2 work conditions (workload, job control) as well as Time 1 emotional demands. The results support a multilevel work stress model with PSC as a plausible primary cause, or “cause of the causes”, of work-related strain. The study adds to the literature that identifies organizational contextual factors as origins of the work stress process.     

毛泽东和农民:一个革命战略形成中的阶级和力量(下)

毛泽东的革命战略经常得不到全面、辩证的阐释。通常的研究不仅过于狭隘地关注于毛泽东对农民的重视,而且也很少考虑他在国家形成过程中的贡献,而这一点其实是内蕴于毛泽东革命战略中的重要维度。毛泽东对农民的重视主要是一种战略和策略的需要,毛泽东从未否认工人阶级在革命中的领导地位,毛泽东是真正的马克思主义者。     

The Penalized Analytic Center Estimator

In a linear regression model, the Dantzig selector (Candès and Tao, 2007 Candès, E., Tao, T. (2007). The Dantzig selector: Statistical estimation when p is much larger than n. Annals of Statistics 35:2313–2351.[Crossref], [Web of Science ®] , [Google Scholar]) minimizes the L₁ norm of the regression coefficients subject to a bound λ on the L_∞ norm of the covariances between the predictors and the residuals; the resulting estimator is the solution of a linear program, which may be nonunique or unstable. We propose a regularized alternative to the Dantzig selector. These estimators (which depend on λ and an additional tuning parameter r) minimize objective functions that are the sum of the L₁ norm of the regression coefficients plus r times the logarithmic potential function of the Dantzig selector constraints, and can be viewed as penalized analytic centers of the latter constraints. The tuning parameter r controls the smoothness of the estimators as functions of λ and, when λ is sufficiently large, the estimators depend approximately on r and λ via r/λ².     

Resiliency factors in the relation between childhood sexual abuse and adulthood sexual assault in college-age women

Research has suggested that childhood sexual abuse (CSA) may be a risk factor for adulthood sexual assault. This study examined associations between CSA experiences, cognitive resiliency variables, and revictimization. Participants were 73 college-age females who completed self-report questionnaires assessing CSA, adult assault, self-efficacy, locus of control (LOC), and coping styles. Sexual assault was categorized as forced or coerced assault based on the tactics used by the perpetrator. Results indicated that CSA alone was the strongest independent predictor of forced adult assault; however, LOC and positive coping were associated with resiliency to coercive sexual assault. The current findings have clinical implications in that LOC and coping styles are characteristics that can be enhanced through therapy.     

Social network evolution during long-term migration: a comparison of three case studies in the South Wales region

Ten years after Poland joined the European Union (EU), a sizable number of the once considered short-term migrants that entered the United Kingdom (UK) post-2004 have remained. From the literature, it is known that, when initially migrating, social networks composed of family and friends are used to facilitate migration. Later, migrants’ social networks may evolve to include local, non-ethnic members of the community. Through these networks, migrants may access new opportunities within the local economy. They also serve to socialise newcomers in the cultural modalities of life in the destination country. However, what if migrants’ social networks do not evolve or evolve in a limited manner? Is cultural integration still possible under these conditions? Using data collected from three case studies in the South Wales region – Cardiff, Merthyr Tydfil and Llanelli – from 2008–2012, the aim of this article is to compare Polish migrants’ social network usage, or lack thereof, over time. This comparison will be used to understand how these social networks can be catalysts and barriers for cultural integration. The findings point to the migrants’ varied use of their local social networks, which is dependent upon their language skill acquisition and their labour market mobility in the destination country.     

A wavelet lifting approach to long-memory estimation

Reliable estimation of long-range dependence parameters is vital in time series. For example, in environmental and climate science such estimation is often key to understanding climate dynamics, variability and often prediction. The challenge of data collection in such disciplines means that, in practice, the sampling pattern is either irregular or blighted by missing observations. Unfortunately, virtually all existing Hurst parameter estimation methods assume regularly sampled time series and require modification to cope with irregularity or missing data. However, such interventions come at the price of inducing higher estimator bias and variation, often worryingly ignored. This article proposes a new Hurst exponent estimation method which naturally copes with data sampling irregularity. The new method is based on a multiscale lifting transform exploiting its ability to produce wavelet-like coefficients on irregular data and, simultaneously, to effect a necessary powerful decorrelation of those coefficients. Simulations show that our method is accurate and effective, performing well against competitors even in regular data settings. Armed with this evidence our method sheds new light on long-memory intensity results in environmental and climate science applications, sometimes suggesting that different scientific conclusions may need to be drawn.
