Living Alone over the Life Course: Cross-National Variations on an Emerging Issue

The increasing proportion of persons living alone has come to be emblematic in many ways of modern Western societies because it represents the importance conceded to the individual and to individual goals at the expense, basically, of the family. Solo living has been interpreted within the context of changing values and preferences, changing personal and conjugal realities, and the changing work contexts so often associated with the Second Demographic Transition. We know little about patterns and trends in living alone over the life course in much of the world because most research to date has concentrated on regional and national portrayals or on living arrangements in later life. This study provides a systematic look at the differences in living alone by age and sex in 113 countries. Our aim is to understand the extent to which behavior differs around the world and the implications this has for society. We also examine the relationship between trends in living alone and levels of human development. Results are taken from three massive datasets: census and survey microdata from IPUMS-international, Demographic Health Surveys, and EU-Labor Force Surveys.     

A semi-parametric Bayesian extreme value model using a Dirichlet process mixture of gamma densities

In this paper, we propose a model with a Dirichlet process mixture of gamma densities in the bulk part below threshold and a generalized Pareto density in the tail for extreme value estimation. The proposed model is simple and flexible for posterior density estimation and posterior inference for high quantiles. The model works well even for small sample sizes and in the absence of prior information. We evaluate the performance of the proposed model through a simulation study. Finally, the proposed model is applied to a real environmental data.     

A prospective study of adolescent mothers’ social competence,children's effortful control and compliance and children's subsequent developmental outcomes

Previous work has established that caregiver and child temperamental characteristics are associated with child compliance. Given the critical role that parents play in this process, and that children of teen mothers are at risk for poorer developmental outcomes, it is important to understand the development of compliance in the context of at‐risk parenting such as adolescent motherhood. The current study examined child compliance (Wave 5; W5) as a mediator of the association between adolescent mothers’ social competence (Wave 4; W4) and children's behavioral and academic outcomes (Wave 6; W6), and whether this mediation varied depending on children's effortful control (W4) in a sample of 204 Mexican‐origin adolescent mothers (M_age at W4 = 19.94, SD = .99) and their children (M_age at W4 = 36.21 months, SD = .45). Adolescent mothers reported on their own social competence and their children's effortful control and externalizing problems; compliance was assessed using observational methods; and academic readiness was assessed using standardized developmental assessments. Findings based on structural equation modeling revealed that adolescent mothers’ social competence was positively related to children's compliance among children with high effortful control, but not among those with low effortful control. Moreover, child compliance mediated the longitudinal association between adolescent mothers’ social competence and child externalizing problems and academic readiness. Discussion focuses on the importance of considering the role of child temperament in understanding how adolescent mothers’ social competence is subsequently associated with children's social and academic adjustment.     

Between cosmopolitanism and ethnic dissolution: Politics,religion and iconic reappropriation in the cult of the Mother of God of Bisila in Equatorial Guinea and Catalonia

ABSTRACT

The cult to the Mother of God of Bisila constitutes one of the main events in Bubi’s sacred calendar. The current representation of this traditional feminine spirit, partially identified to the Virgin Mary, stems from the sculpture made by the Modest Gené in 1968, when Equatorial Guinea was still a Spanish colony. The creation of this image formed part of a strategy of evangelization through religious syncretism. Yet, the importance of Bisila is not only religious but mainly political and identity-related: historically, Bisila has symbolised the cultural resistance of Bubi people. Today, the cult of Bisila is undergoing a deep transformation. In Guinea, we witness a strong contrast between the areas in which the cult tends to become an interethnic ceremony and those in which it preserves its marked Bubi character. In Catalonia, Bisila’s followers have strategically adopted a religious narrative based on the ideas of cosmopolitanism and pan-africanism aimed at presenting their cult as an integrative celebration. Based on a multi-situated ethnographic fieldwork, and on an in-depth historical research, this article discusses the tensions between universalism and ethnic singularity that lie within this unexplored cult, through which some of the main conflicts of contemporary Bubi community can be grasped.

Some Sort of Help for the Poor: Blurred Perspectives on Asylum

This article explores the distinction between economic and forced migration by following three Guatemalan day labourers in northern California who “discover” the possibility of asylum after coming to the US as undocumented migrants. Vaguely understood as “some sort of help for Guatemalans,” asylum acquires a confusing assortment of meanings for these men as they hear about it from other migrants and local NGOs. They thus face two problems that hinder their application. The first is that their own rendering of their reasons for migration can look both “forced” and “voluntary.” The second is that beyond the validity of their claims, their life in the US is embedded in the marginalization of the cohort of undocumented migrants they join. Whatever the outcome, the men thus continue to follow the logics of fear and mistrust that characterize undocumented day labourers in the United States.     

Mothers, Fathers, Peers, and Mexican-Origin Adolescents' Sexual Intentions

Drawing on a symbolic-interaction perspective and a compensation model, the processes linking mother-and father-adolescent relationship qualities, deviant peer affiliations, and adolescents' sexual intentions were investigated for 246 Mexican-origin youths born in the United States and in Mexico using multiple-group structural equation models. Deviant peer affiliations significantly mediated the relations between paternal acceptance and sexual intentions and between disclosure to mothers and sexual intentions for U.S.-born youths but not for Mexico-born youths. Findings highlight the importance of examining variability as a function of youth nativity.     

Comparing mining and manufacturing supply chain processes: challenges and requirements

The mineral raw materials industry is essential for manufacturing by providing the basic materials for their value adding processes. In the last decade, the integration of operations of the industry within global manufacturing supply chains has progressed greatly. The processes of the different stakeholders have been extensively analysed and modelled according to standardised frameworks such as the supply chain operations reference (SCOR) model. However, as of today, not all stakeholders are integrated to the same extent. Especially, in the early part of the supply chain, deep integration of the mineral raw materials industry is still an exception. This industry and its processes differ greatly from the average manufacturing company’s processes. Not being directly comparable results in the absence of applications of standardised modelling tools for supply chains like the above-mentioned SCOR model. These circumstances hinder the integration, understanding and exchange between industries that rely significantly on each other. In a first attempt to create a basis for further research, this study analyses, elaborates and compares the challenges and requirements of supply chain processes, with a special focus on sourcing processes, in manufacturing and mining. Based on these findings, an adaption of the SCOR model towards applicability in mining and mining supply processes is presented, followed by a critical discussion of the results and implications, later concluded by a short outlook on further research.     

Cross-lagged relationships between workplace bullying,job satisfaction and engagement: Two longitudinal studies

Abstract

Workplace bullying has been defined as a stressor that has negative consequences. However, the direction of the bullying–well-being relationship has been largely based on cross-sectional findings, which does not permit conclusions in terms of causality. The purpose of this research was to investigate the cross-lagged relationships between bullying and job-related well-being. We hypothesized that Time 1 bullying predicted Time 2 job-related well-being over time (normal causation model). In addition, we compared alternative models (baseline or stability, reversed, and reciprocal models). Our hypothesis was examined in two longitudinal studies with full two-wave panel designs in Belgian employees. In Study 1 (N=312), the time lag was six months, and in Study 2 (N=369), the time lag was two years. Results of structural equation modelling (SEM) analyses partially supported our hypothesis. Specifically, it was found that Time 1 bullying predicted Time 2 dedication in Study 1, and Time 2 job satisfaction in Study 2. There was no significant cross-lagged effect of job-related well-being on bullying at work. Overall, these findings suggest that bullying can be considered as a cause, rather than aconsequence of job-related well-being.     

Moderating effects of social support in shiftworking and non-shiftworking nurses

In this study the causal relationships between work characteristics, in terms of job demands and job resources, and both targets’ and perpetrators' reports of workplace bullying, are investigated. In line with the Job Demands-Resources model and the bullying literature, we assumed that both high job demands (i.e. workload, role conflict and job insecurity) and low job resources (i.e. task autonomy, social support and skill utilization) increase bullying over time (i.e. normal causation). Our sample included 177 employees of various establishments of a large Belgian organization. The results of structural equation modelling analyses partially supported our hypothesis. As expected, we found that T1 job demands related positively to targets’ reports of bullying at T2 one year later, and that T1 job resources related negatively to T2 targets’ reports of bullying. Unexpectedly, there was no significant cross-lagged effect of T1 job demands and resources on T2 perpetrator's reports of bullying. No evidence was found for reverse causation or reciprocal effects. Overall, at least for targets, these findings support the validity of the theoretical models postulating a causal link from work characteristics to workplace bullying.
