Alcohol Consumption Among University Students in North Rhine–Westphalia,Germany—Results From a Multicenter Cross-sectional Study

Abstract

Objective: To assess alcohol use and problem drinking among university students in the German Federal State of North Rhine–Westphalia (NRW) and to examine the associated factors. Method: A multicenter cross-sectional study was conducted in 16 universities in 2006–2007 in NRW by a standardized questionnaire and 3,306 students provided information (response rate of 88%). Problem drinking was measured by the CAGE questionnaire. Results: Alcohol consumption in the last 3 months was reported by >90 % of students. About 80% reported heavy drinking, and 20% displayed problem drinking. Male students, students living in residence halls, and students from sport faculties had a higher risk of heavy drinking and problem drinking. When students were compared across study years, frequency of heavy drinking decreased with higher semesters. Conclusions: Overall, heavy drinking and problem drinking are common among university students in this sample. Intervention programs should be designed for students at a particularly high risk.     

Who has Housing Affordability Problems? Disparities in Housing Cost Burden by Race, Nativity, and Legal Status in Los Angeles

Housing costs are a substantial component of US household expenditures. Those who allocate a large proportion of their income to housing often have to make difficult financial decisions with significant short-term and long-term implications for adults and children. This study employs cross-sectional data from the first wave of the Los Angeles Family and Neighborhood Survey collected between 2000 and 2002 to examine the most common US standard of housing affordability, the likelihood of spending 30 % or more of income on shelter costs. Multivariate analyses of a low-income sample of US-born Latinos, whites, African Americans, authorized Latino immigrants, and unauthorized Latino immigrants focus on baseline and persistent differences in the likelihood of being cost burdened by race, nativity, and legal status. Nearly half or more of each group of low-income respondents experience housing affordability problems. The results suggest that immigrants’ legal status is the primary source of disparities among those examined, with the multivariate analyses revealing large and persistent disparities for unauthorized Latino immigrants relative to most other groups. Moreover, the higher odds of housing cost burden observed for unauthorized immigrants compared with their authorized immigrant counterparts remains substantial, accounting for traditional indicators of immigrant assimilation. These results are consistent with emerging scholarship regarding the role of legal status in shaping immigrant outcomes in the United States.     

An Evaluation of the NERJIT Priority Rule in a Kanban‐Controlled Flowshop

Significant progress in production and information technologies and innovations in management of operations during the last couple of decades have made the production of small lots and deployment of Just‐In‐Time (JIT) concepts in flowshops possible. As a result, some researchers and practitioners have been seeking to improve the performance of non‐repetitive systems using JIT concepts. In this process, the JIT concepts that were originally designed for mass production have been modified to adapt JIT to non‐repetitive systems. This article uses a priority rule that is based on real‐time demand and production information for sequencing jobs in a kanban‐controlled flowshop. The analysis of the effect of this priority rule; the number of kanbans; the length of the withdrawal cycle; First‐Come, First‐Served (FCFS); and Shortest Processing Time (SPT) on four performance measures—customer wait time, total inventory, input stock‐point inventory, and output stock‐point inventory, shows that the use of this priority rule results in a significant reduction of customer wait time and a slight decrease in inventory.     

Multivariate survival mixed models for genetic analysis of longevity traits

A class of multivariate mixed survival models for continuous and discrete time with a complex covariance structure is introduced in a context of quantitative genetic applications. The methods introduced can be used in many applications in quantitative genetics although the discussion presented concentrates on longevity studies. The framework presented allows to combine models based on continuous time with models based on discrete time in a joint analysis. The continuous time models are approximations of the frailty model in which the baseline hazard function will be assumed to be piece-wise constant. The discrete time models used are multivariate variants of the discrete relative risk models. These models allow for regular parametric likelihood-based inference by exploring a coincidence of their likelihood functions and the likelihood functions of suitably defined multivariate generalized linear mixed models. The models include a dispersion parameter, which is essential for obtaining a decomposition of the variance of the trait of interest as a sum of parcels representing the additive genetic effects, environmental effects and unspecified sources of variability; as required in quantitative genetic applications. The methods presented are implemented in such a way that large and complex quantitative genetic data can be analyzed. Some key model control techniques are discussed in a supplementary online material.     

Nearest neighbor hazard estimation with left-truncated duration data

Duration data often suffer from both left-truncation and right-censoring. We show how both deficiencies can be overcome at the same time when estimating the hazard rate nonparametrically by kernel smoothing with the nearest-neighbor bandwidth. Smoothing Turnbull’s estimator of the cumulative hazard rate, we derive strong uniform consistency of the estimate from Hoeffding’s inequality, applied to a generalized empirical distribution function. We also apply our estimator to rating transitions of corporate loans in Germany.     

Working life and retirement pensions in Spain: The simulated impact of a parametric reform

This article aims to offer an ex ante evaluation of the impact of a parametric reform of the Spanish pension system that would involve increasing the reference period used to calculate benefits, an approach proposed many times by various actors in the socio‐economic field. Such gradual change may be categorized as a non‐structural reform of the pension system. This contrasts with reforms of a structural nature that have been very popular in Latin America and elsewhere, involving the creation of defined contribution individual account schemes. As regards the parametric reform proposed in this article, the main findings indicate that it would have a small but negative impact on pension income for pensioners and would reduce income distribution.     

Migration and livelihood constellations: Assessing common themes in the face of environmental change in Somalia and among Agro-Pastoral peoples

Research on migration has become more challenging due to at least four factors: (1) more complex migration traditions; (2) the development of migration economies that engage many types of migrants from ever more social and cultural backgrounds; (3) increasing likelihood of climate change-driven environmental migration; and (4) increasing likelihood of conflict-based migration in some contexts. These developments have shaken economic theories of migration and have encouraged interdisciplinary, methodologically mixed, qualitative and quantitative research and analysis. From a review of the literature, we have gleaned 11 common themes about environmental, economic and conflict migration that we differentiate by process (migration behaviours that are still evolving) and patterns (migration behaviours that have become customary). We then consider how positive and negative dimensions of migration can be captured and represented with close attention to livelihood constellations (multiple economic activities combined by individuals, households and families). Finally, focusing on Somalia and agro-pastoral peoples generally, where recent environmental and conflict migration have been added to decades of economic migration and centuries of seasonal, environmental migration associated with pastoralism, we combine historical and qualitative work to demonstrate the value of a livelihood constellation perspective.     

The use of diaries for understanding the experience of health and illness

While diaries as a method have a long tradition in sociological research, few studies to date have demonstrated its value for studying health and illness. This article intends to illustrate the importance of this method for health research. The implications of the use of solicited diaries to conduct research within the field of health and illness are discussed. The contributions that the method can make to sociological research on health and illness are explored, namely the potential to capture the everyday of ill people and their family members. Indeed, this method offers an opportunity to access the experience of illness in a multidimensional approach which is not easy for researchers to catch using other methods. The article aims to present an overview of the significance of the use of diaries in health research and will make a novel contribution to the sociology of health and illness.     

Reintegration upon return: insights from Ecuadorian returnees from Spain

Using the ECM2 survey data on Ecuadorian migrants returning from Spain, we investigate the determinants of reintegration upon return. We study how the migration experience, but also the before‐ and after‐migration characteristics, correlate with migrants’ outcomes upon return. We adopt a broad conception of reintegration, considering jointly labour market‐related outcomes that proxy for structural reintegration and subjective indicators that provide insights on sociocultural reintegration. The determinants of these two types of outcomes appear to be different: reintegration indeed encompasses multiple dimensions which cannot be captured by a single indicator. Our results suggest that return assistance programmes’ efficiency in helping reintegration could be improved by (I) targeting, ex‐ante, returnees who plan to launch their own business, and, ex‐post, the most vulnerable workers (women, older returnees, unemployed), and (ii) facilitating the labour market integration of foreign‐educated returnees. They also call for further research to better understand the consequences of these programmes.     

‘I open the coffin and here I am’: disability as oppression and education as liberation in the construction of personal identity

This article presents a case study focused on the experiences of Rafael, a resilient young musician. The research is based on 180 records made through interviews, focus groups, observations and documentary collection, involving 190 informants. The data analysis shows that social systems create subordinated and stigmatised conditions of experience for people with disabilities which lead to social exclusion and reification. This understanding of disability as oppression (which is the ‘coffin of the dead’) can be combated by means of education, understood as resistance to inequality. This can be effected by questioning the social order and power relationships, thus striving to produce the possibility of being a subject. In this way Rafael has been able to construct his identity relatively autonomously, challenging social mandates that led him to exclusion and denied his existence as a subject. In his own words: ‘I open the coffin and here I am’.
