Maternal union instability and childhood mortality risk in the Global South, 2010–14

Efforts to improve child survival in lower-income countries typically focus on fundamental factors such as economic resources and infrastructure provision, even though research from post-industrial countries confirms that family instability has important health consequences. We tested the association between maternal union instability and children’s mortality risk in Africa, Latin America and the Caribbean, and Asia using children’s actual experience of mortality (discrete-time probit hazard models) as well as their experience of untreated morbidity (probit regression). Children of divorced/separated mothers experience compromised survival chances, but children of mothers who have never been in a union generally do not. Among children of partnered women, those whose mothers have experienced prior union transitions have a higher mortality risk. Targeting children of mothers who have experienced union instability—regardless of current union status—may augment ongoing efforts to reduce childhood mortality, especially in Africa and Latin America where union transitions are common.     

To ITV or Not to ITV: A Comparison of Hybrid and Web-enhanced Approaches to Teaching a Macro-course in Human Behavior in the Social Environment

Hybrid education includes an online component and interaction between students and teacher by televised sound and image. This approach contrasts dramatically with traditional face-to-face teaching and classroom teaching modalities enhanced by Web-based tools. Should educators in “human behavior and the social environment” (HBSE) use hybrid technologies? This study explores the differences and similarities in student satisfaction and learning outcomes between a hybrid and a face-to-face Web-enhanced macro-course in HBSE. Results suggest that hybrid and Web-enhanced course delivery methods do not differently impact student learning. Students did report greater satisfaction with some but not all aspects of the hybrid sections.     

‘Ways of Remembering’: Transatlantic Connections and African Diaspora's Homecoming in the Republic of Benin

Abstract

Since the seventeenth century, the Atlantic ‘perimeter’ has been characterised by exchanges of commodities, bodies and cultural productions. Within this space, West Africa has established itself as an ‘ancestral land’: a pivotal physical and imagined location for its diaspora. Exploring how a ‘homeland’ is constructed, the article analyses practices of homecoming in the contemporary Republic of Benin. It argues that the particular historical conjuncture of the early 1990s, mainly characterised by the democratic transition, has allowed the restoration of Atlantic connections. Aspiring to establish a vibrant tourism industry, the new government strongly encouraged African American homecomings, commemorating the slave trade and celebrating diasporic cultures. The Vodun religion, because of its propagation across the New World through the slave trade, became the core symbol of this reunion, the very evidence of the strength of ancestral linkages and a foundation for black commonality. Reframing notions of ancestry and transnational belongings, the article examines how the insertion of Benin into global, economic and cultural circuits has led to the emergence of new cultural practices, meanings and subjectivities, both related to national and diasporic spaces.     

Competition between laboratory populations of green leafhoppers,Nephotettix spp. (Homoptera: Cicadellidae)

Summary Intra- and interspecific competition between laboratory populations of four green leafhoppers,Nephotettix spp. was studied in the laboratory under three different temperature regimes of 24°C, 27°C and 30°C. For the single-species population of the three tropical species, the equilibrium density increased as the temperature increased. On the other hand, for the temperature speciesN. cincticeps, the highest equilibrium density was at the intermediate temperature and the lowest at high temperature. Interspecific interactions between two tropical (N. virescens vs.N. nigropictus), a tropical and a temperature (N. virescens vs.N. cincticeps) and a rice-feeding and a grass-inhabiting (N. virescens vs.N. malayanus) Nephotettix species were also studied in the laboratory at the three temperature regimes. Temperature differentially affected the outcome of competition between twoNephotettix species. BetweenN. virescens andN. nigropictus, the latter was more successful over the former at low and intermediate temperatures, while the former was more successful at high temperature. BetweenN. virescens andN. cincticeps, the temperate species inhibited the growth of the tropical species at low temperature while the tropical species inhibited the growth of the temperate species at high temperature. At intermediate temperature, the population ofN. virescens persisted at a slightly higher density over the population ofN. cincticeps. Between the rice-feedingN. virescens and the grass-inhabitingN. malayanus, regardless of temperature the population density of the latter was greatly reduced and later became extinct while the population of the former continued its growth. These consequences of competition between twoNephotettix species conformed fairly well to those predicted by theLotka-Volterra model using demographic parameters specified for each species.     

Frequentist and Bayesian approaches for a joint model for prostate cancer risk and longitudinal prostate-specific antigen data

The paper describes the use of frequentist and Bayesian shared-parameter joint models of longitudinal measurements of prostate-specific antigen (PSA) and the risk of prostate cancer (PCa). The motivating dataset corresponds to the screening arm of the Spanish branch of the European Randomized Screening for Prostate Cancer study. The results show that PSA is highly associated with the risk of being diagnosed with PCa and that there is an age-varying effect of PSA on PCa risk. Both the frequentist and Bayesian paradigms produced very close parameter estimates and subsequent 95% confidence and credibility intervals. Dynamic estimations of disease-free probabilities obtained using Bayesian inference highlight the potential of joint models to guide personalized risk-based screening strategies.     

Spanish validation of the Servant Leadership Short Scale for young adults and adolescents / Validación de la Escala de Liderazgo de Servicio Versión Abreviada en español para jóvenes adultos y adolescentes

The aim of the current study was to validate a shortened Spanish version of the Servant Leadership Profile (SLP). In Study 1, a number of experts evaluated and reduced the original scale to 14 items and named the revised version the Servant Leadership Short Scale (SLSS). An exploratory factor analysis conducted with a sample of 1,001 students revealed two possible structure solutions, a one-factor solution and a two-correlated factor solution. Study 2 used a different sample of 456 students to examine the explored structures using confirmatory factor analysis. A one-factor solution was proposed (χ²/df = 3.4, CFI = .91, TLI = .90, RMSEA = .07, SRMR = .06). Finally, in Study 3, servant leadership was used as a predictor of self-efficacy (b = .685, p < .001) and demonstrated good predictive validity. This model explained 41.55% of the variance on self-efficacy. Reliability analyses of the three studies showed that this 14-item Spanish version had high internal consistency. Together, the results of the three studies support the application of the SLSS in future research.     

Beyond Study Abroad: A Human Rights Delegation to Teach Policy Advocacy

Advancement of human rights is a core competency in the social work curriculum. Presented is a model to teach policy practice from a human rights perspective based on a violence-against-women delegation visit to Guatemala. Postdelegation policy advocacy responses included White House and State Department briefings on the problems, including femicide. Case examples of witnessed testimony about human rights violations, including rape, femicide, and human trafficking, reflect the unique and dynamic nature of social work practice in a global context. We link Council on Social Work Education core competencies in policy practice and human rights to experiential learning strategies used by the delegation and derive lessons learned to advance human rights education for the profession.     

Childhood nutrition and later fertility: Pathways through education and pre-pregnant nutritional status

Better childhood nutrition is associated with earlier physical maturation during adolescence and increased schooling attainment. However, as earlier onset of puberty and increased schooling can have opposing effects on fertility, the net effect of improvements in childhood nutrition on a woman’s fertility are uncertain. Using path analysis, we estimate the strength of the pathways between childhood growth and subsequent fertility outcomes in Guatemalan women studied prospectively since birth. Height for age z score at 24 months was positively related to body mass index (BMI kg/m²) and height (cm) in adolescence and to schooling attainment. BMI was negatively associated (−0.23 ± 0.09 years per kg/m²; p < . 05) and schooling was positively associated (0.38 ± 0.06 years per grade; p < .001) with age at first birth. Total associations with the number of children born were positive from BMI (0.07 ± 0.02 per kg/m²; p < .05) and negative from schooling (−0.18 ± 0.02 per grade; p < .01). Height was not related to age at first birth or the number of children born. Taken together, childhood nutrition, as reflected by height at 2 years, was positively associated with delayed age at first birth and fewer children born. If schooling is available for girls, increased growth during childhood will most likely result in a net decrease infertility.     

Teaching Human Development: Current Theoretical Deficits and a Theory-Enriched “Models,Metaphors, and Maps” Remedy

Contemporary social work education in the area of human development is anemic. There is too little coverage of the theoretical frameworks, models, theorists, competencies, and functions necessary to prepare students for careers that apply developmental science. This premise is supported by a content analysis of 12 human development textbooks and 44 course outlines. Three major strategies—teaching by models, teaching by metaphors, and teaching by maps—are described as methods for enriching human development education. Four alternatives for including theoretical content are also offered.     

Adding the “Symbolic” to Interactionist Practice: A Theoretical Elaboration of William Schwartz' Legacy to Group Workers

Symbolic interactionism is one of the premier theoretical perspectives on group life, but group work theorists have neglected it. This article provides metatheoretical reflections on the legacy of William Schwartz and the stalled project of theorizing about the communicative foundation of groups. Exemplars in the interactionist tradition are profiled, and their conceptual and practical contributions to a “symbolic” interactionist group theory are highlighted. The structure of interactionist theory is mapped, and a set of distinctive concepts and assumptions organized around the construct of symbolic practices is presented. The article concludes with a call to group workers to harvest the fruits of the interactionist theoretical and research program.
