Since market‐oriented economic reform was launched in China in the 1980s, unemployment has been recognized by the government. This paper focuses on the differences in joblessness in rural and urban areas between rural migrant workers, peasants, and urban citizens. The results indicate that people in rural areas frequently lose their jobs, which differs from the traditional perception. There is a significantly lower jobless rate in urban areas. In contrast to the results of previous studies, the employment situation of rural migrant workers is closer to urban citizens rather than peasants. Logistic regression results show that the elderly, women, and less educated citizens have a higher likelihood of joblessness, both in urban and rural areas. Minorities have a lower likelihood of joblessness in rural areas and a higher likelihood in urban areas. Chinese Communist Party members and people without dependent children have a lower likelihood of joblessness in urban areas.  相似文献

Political tolerance—the willingness to extend civil liberties to traditionally stigmatized groups—is pivotal to the functioning of democracy and the well‐being of members of stigmatized groups. Although political tolerance has traditionally been more common among American elites, we argue that as tolerance has increased, it has also diffused to less educated and less affluent segments of the population. The relative stability of political attitudes over the life course and the socialization of more recent birth cohorts in contexts of increased tolerance suggest that this diffusion of tolerance occurs across birth cohorts rather than time periods. Using age‐period‐cohort models and more than three and a half decades of repeated cross‐sectional survey data, we find persistent and robust across‐cohort declines in the importance of both income and higher education in determining levels of political tolerance. Declines in the effects of socioeconomic status are evident with tolerance toward all five out‐groups in the analysis—anti‐religionists, gays and lesbians, communists, militarists, and racists—but to varying degrees. These findings fit with a model of changes in public opinion, particularly views of civil and political rights, through processes of cultural diffusion and cohort replacement.  相似文献

This research was motivated by our goal to design an efficient clinical trial to compare two doses of docosahexaenoic acid supplementation for reducing the rate of earliest preterm births (ePTB) and/or preterm births (PTB). Dichotomizing continuous gestational age (GA) data using a classic binomial distribution will result in a loss of information and reduced power. A distributional approach is an improved strategy to retain statistical power from the continuous distribution. However, appropriate distributions that fit the data properly, particularly in the tails, must be chosen, especially when the data are skewed. A recent study proposed a skew-normal method. We propose a three-component normal mixture model and introduce separate treatment effects at different components of GA. We evaluate operating characteristics of mixture model, beta-binomial model, and skew-normal model through simulation. We also apply these three methods to data from two completed clinical trials from the USA and Australia. Finite mixture models are shown to have favorable properties in PTB analysis but minimal benefit for ePTB analysis. Normal models on log-transformed data have the largest bias. Therefore we recommend finite mixture model for PTB study. Either finite mixture model or beta-binomial model is acceptable for ePTB study.  相似文献

Unacceptable forms of work (UFW) have been identified as an “area of critical importance” for the ILO as it approaches its centenary. Yet there is currently no comprehensive elaboration of the dimensions, causes or manifestations of UFW. This article reports on a research project that has proposed such a framework. The article first investigates and reconceptualizes key discourses on contemporary work to identify their contribution to an analytically rigorous conception of UFW. It then outlines a novel Multidimensional Model that has been designed for use by local policy actors in identifying and targeting UFW in countries across a range of income levels.  相似文献

Problem

Rates of medical interventions in childbirth have greatly increased in the Western world.

Background

Women’s attitudes affect their birth choices.

Aim

To assess women’s attitudes towards the medicalization of childbirth and their associations with women’s background as well as their fear of birth and planned and unplanned modes of birth.

Methods

This longitudinal observational study included 836 parous woman recruited at women’s health centres and natural birth communities in Israel. All women filled in questionnaires about attitudes towards the medicalization of childbirth, fear of birth, and planned birth choices. Women at <28 weeks gestation when filling in the questionnaire were asked to fill in a second one at ~34 weeks. Phone follow-up was conducted ~6 weeks postpartum to assess actual mode of birth.

Findings

Attitudes towards medicalization were more positive among younger and less educated women, those who emigrated from the former Soviet Union, and those with a more complicated obstetric background. Baseline attitudes did not differ by parity yet became less positive throughout pregnancy only for primiparae. More positive attitudes were related to greater fear of birth. The attitudes were significantly associated with planned birth choices and predicted emergency caesareans and instrumental births.

Discussion

Women form attitudes towards the medicalization of childbirth which may still be open to change during the first pregnancy. More favourable attitudes are related to more medical modes of birth, planned and unplanned.

Conclusion

Understanding women’s views of childbirth medicalization may be key to understanding their choices and how they affect labour and birth.  相似文献

ABSTRACT

Making informed financial decisions is crucial to the wellbeing of Chinese migrant workers. Using interview survey data (= 329), this study examined financial knowledge and behaviors of migrant workers in China. Results showed that participants demonstrated low levels of financial knowledge (51.4%) and beneficial financial behaviors (51.0%). Multivariate results indicated that a modest proportion of the variance in financial behaviors was explained by financial knowledge, attitudes, and socio-demographic characteristics (e.g., marital status and income). Findings underscore the importance of disseminating culturally-relevant educational interventions to financially at-risk, low-paid migrant workers in China.  相似文献

Mental health professionals are well versed in addressing multiple adolescent risky behaviours and play a primary role in the identification of and referral process and service provision for young people who engage in such behaviours. Given their ‘person-in-environment’ approach, training in multi-sectoral collaboration, and awareness of social policies, social workers are especially equipped to provide needed mental health services to young people. The aim of the current study was to examine Israeli mental health professionals’ awareness of and attitudes towards adolescent high-risk behaviours, including gambling. Child psychologists, social workers and school counsellors (N = 273) completed an online survey addressing concerns related to high-risk behaviours. Findings revealed that social workers perceived gambling as being among one of the least concerning adolescent mental health issues and reported feeling the least confident in their abilities to provide services to young people with gambling problems. The results suggest the importance of youth gambling addictions being incorporated into social work training curricula.  相似文献

There is a growing literature investigating the association between coping and work stress among social workers. An area that remains under-researched is the association between work–family conflict and coping. The present study explored the coping strategies adopted by social workers in dealing with the competing demands emanating from their work and family domains. In a larger study involving 439 Australian social workers, we analyzed the responses to two open-ended questions that explored the challenges experienced by social workers in meeting their work and family demands, and the coping strategies they adopt to deal with these challenges. The findings confirm that social workers experience work–family conflict and they adopt several coping strategies to deal with it including support from supervisors and colleagues, cognitive reframing, timely communication, setting clear expectations, time management, job flexibility and developing personal hobbies. We discuss the implications of our findings for social work policy and practice.  相似文献

An explanatory cross‐sectional investigation was employed to assess how well masters‐level social work (MSW) programs in the State of New York prepare students for practice with problem drinkers. The following areas were explored: (1) the incorporation of alcohol‐related coursework and field placement opportunities within MSW programs; (2) the relationship between students' completion of alcohol‐related courses and field placements and their subsequent ability to diagnose clients with alcohol problems, their willingness to work with problem drinkers, and their levels of alcohol‐related knowledge; and (3) subjects' levels of alcohol‐related knowledge in relation to their diagnostic ability and their willingness to work with problem drinkers. The sample consisted of 89 MSW‐level social work practitioners, who were active members of the New York State Chapter of the National Association of Social Workers (NASW) during the fall of 2005. Fewer than 3% of the sample reported the completion of an alcohol‐related course as a mandatory degree requirement and only 29.5% of the sample acknowledged the completion of an alcohol‐related field placement. These findings suggest that a possible gap exists in what social workers are being taught and what they need to know to successfully work with problem drinkers. The findings indicate that clients with alcohol problems are at risk of going untreated due to social workers' inability to correctly diagnose them as a result of insufficient training in the area of alcohol studies.  相似文献
