This article provides insights into the role of the nuclear family for refugees' social capital in Austria, with a focus on gender-specific differences. We use a multimethod approach, based on quantitative data from a survey with 548 refugees from Syria and Afghanistan and semi-structured group discussions (N = 17 informants). In our analysis, we study frequency of contacts in first language and in German, as proxies for the bonding and bridging social capital. Marital status, childlessness and family work were identified as important factors: Frequency of contact substantially varied by gender and family context. Of all surveyed groups, married childless women and married men with children had the least contacts in both languages. Although an unequal distribution of childcare may limit women's time resources, we observed a positive association between motherhood and frequency of contact in German.  相似文献

Using microdata from the European Union Labour Force Survey (EU-LFS) and aggregate indicators of labour market institutions, this article compares the job quality of native and non-native workers across European countries and analyses the impact of the institutional settings on the job quality differential between both groups. The LFS is used to measure a job quality index for the period 2005–2017. We find that some immigrant groups fare worse than natives, the contribution of the “composition effect” to explain this differential is large, and the institutional framework affects the immigration gap in job quality. In particular, some labour market institutions (more centralized wage bargaining, stricter employment protection legislation) tend to be detrimental for immigrants relative to natives, while integration policies seem to work well in reducing these differences.  相似文献

To prevent and control foodborne diseases, there is a fundamental need to identify the foods that are most likely to cause illness. The goal of this study was to rank 25 commonly consumed food products associated with Salmonella enterica contamination in the Central Region of Mexico. A multicriteria decision analysis (MCDA) framework was developed to obtain an S. enterica risk score for each food product based on four criteria: probability of exposure to S. enterica through domestic food consumption (Se); S. enterica growth potential during home storage (Sg); per capita consumption (Pcc); and food attribution of S. enterica outbreak (So). Risk scores were calculated by the equation Se*W1+Sg*W2+Pcc*W3+So*W4, where each criterion was assigned a normalized value (1–5) and the relative weights (W) were defined by 22 experts’ opinion. Se had the largest effect on the risk score being the criterion with the highest weight (35%; IC95% 20%–60%), followed by So (24%; 5%–50%), Sg (23%; 10%–40%), and Pcc (18%; 10%–35%). The results identified chicken (4.4 ± 0.6), pork (4.2 ± 0.6), and beef (4.2 ± 0.5) as the highest risk foods, followed by seed fruits (3.6 ± 0.5), tropical fruits (3.4 ± 0.4), and dried fruits and nuts (3.4 ± 0.5), while the food products with the lowest risk were yogurt (2.1 ± 0.3), chorizo (2.1 ± 0.4), and cream (2.0 ± 0.3). Approaches with expert-based weighting and equal weighting showed good correlation (R= 0.96) and did not show significant differences among the ranking order in the top 20 tier. This study can help risk managers select interventions and develop targeted surveillance programs against S. enterica in high-risk food products.  相似文献

Voluntary sustainability standards (VSSs) in global production networks (GPNs) have grown significantly in prominence. Existing research largely assumed that VSSs create linear upgrading outcomes for all GPN actors and has studied VSSs from the point of adoption in the GPNs, rather than a broader range of stages in their lifecycle. To address these limitations, and building on literature around power and agency in GPNs, we develop the constellation of priorities (CoP) model to unpack the diverse and often diverging boardroom (Northern lead firm) and local (Southern supplier) priorities involved in such standards. Through in-depth fieldwork on horticulture in Kenya and cocoa in Nicaragua across the VSS lifecycle, we find significant divergences in priorities between farmer groups in both countries and lead firms in the UK and Germany. We demonstrate analytically and empirically that diverging priorities coupled with power asymmetries produced contestations, leading to simultaneous economic and environmental downgrading, and social upgrading.  相似文献

The researchers sought to understand the typical development of social referencing and object mastery motivation in infancy and to determine the relationship between social referencing and object mastery behaviors in infants from 7 to 22 months of age. The study included 36 infants who were followed as part of a longitudinal study of at-risk infants but were not determined to need care in the neonatal intesive care unit at birth. Both mastery behaviors of persistence and success showed a statistically significant effect of age, while social behaviors remained stable from 7 to 22 months. Social behaviors at 7 and 10 months were correlated with persistence at 22 months and success at 16 to 22 months demonstrating that early social referencing predicts object mastery behaviors in later infancy. Further research should determine if this trend extends to early childhood.  相似文献

Public debates and controversies on moral issues have gained visibility in recent decades in both Spain and Mexico. Conservative Catholic groups and networks are increasingly playing a crucial role in raising and framing highly morally charged themes in the public arena, especially on intimacy-related policies, including sexual and reproductive freedoms. A new generation of young Catholic leaders becoming key political agents has emerged in this scenario. They are fostering new mobilisation repertoires in the public sphere (e.g., digital activism and public performances) and promoting new political narratives merging moral, cultural, and religious elements. These highly religious and conservative young Catholics consider themselves part of a cultural/cognitive minority and feel entitled to become what Howard Becker termed “moral entrepreneurs.” Most have been educated in Catholic schools and belong to Catholic movements. Still, they can also navigate secular politics and strategically use different regimes of justification and action. Within this context, the article aims to examine and compare the intersection of historical trends and the relevance of individual biographies to understand the role of these young Catholics in the public space in both countries.  相似文献

This longitudinal two-wave cross-national study investigated whether intentions, friends' substance use, and parent-adolescent substance-use specific communication predict adolescent alcohol and cannabis use 1 year later, while estimating reversed links. The temporal order between these two substances was also examined. We used multi-group cross-lagged panel modeling on data from 2 ethnically and socioeconomically diverse samples: Sint Maarten (N = 350; Mage = 14.19) and the Netherlands (N = 602; Mage = 13.50). Results showed that in the Netherlands, cannabis use predicts more subsequent problems (alcohol use, intention to use cannabis, and affiliation with cannabis-using friends). But for Sint Maarten, alcohol use predicts more subsequent problems (cannabis use, intention to use alcohol, and affiliation with alcohol-using friends). These opposing results demonstrate that caution is warranted when generalizing results across countries.  相似文献
