In broad terms, the division in Europe between countries with very low fertility and countries with sustainable fertility matches Esping-Anderson’s classification of the same countries into ‘conservative’ and ‘social democratic’ (Esping-Anderson 1990). A central difference between these two types relates to their preferred models of the family. The conservative countries hold more to the ‘breadwinner’ model of the family while the social democratic countries seek higher levels of gender equity within the family and in the workplace. State support in both conservative and social democratic countries is designed to be consistent with these differing views of the family. Would we then not expect fertility to be very low in Esping-Anderson’s third group of countries, the ‘liberal’ countries, essentially English-speaking countries? By the Esping-Anderson definition, liberal countries are notable for their lack of support for families from public sources. Instead, according to Esping-Anderson, families must rely upon market provision for the services that they may need to combine work and family and they must rely on market employment to generate the income required to support their children. Contrary to this theory, whether measured by contemporary cross-sectional fertility or completed cohort fertility, with the exception of Canada, English-speaking countries now have the highest fertility rates among the countries that were classified by Esping-Anderson. Given the strength of theoretical explanation that arises from comparative studies of fertility in Europe, the paper examines why fertility in English-speaking countries seems not to follow expectation.  相似文献

This article investigates the relationship between crime and quality of life in Saskatoon, Canada. The city has one of the highest crime rates in the country and has been referred to as the ‘Crime Capital of Canada’, a label that comes as a surprise to many residents and causes considerable concern among others. The aim of this research is to penetrate beyond sensational news headlines and bald crime statistics. The paper evaluates how perceptions of crime and safety affect the quality of life of residents living in neighbourhoods of different socio-economic status and geographic location. Both quantitative and qualitative time series data is analyzed in a sample of neighbourhoods over the period 2001–2004–2007. The findings of the data analysis are interpreted with respect to issues relating to the fear of crime, avoidance behaviour, risk minimization, social cohesion and community building.  相似文献

This phenomenological study aims at understanding lived experiences of college seniors and recent college graduates with physical disabilities seeking employment opportunities after graduation in the USA The extensive interviews revealed that participants’ attitudes about and experiences with disability are diverse (pain to pride, denied accommodation to support); their major areas of concern are their own marketable skills and credentials as well as accessibility and accommodation in workplaces; continued education beyond the baccalaureate is a priority for many participants rather than an immediate transition to work; and the Office of Disability and professors were considered important advising agencies. Even among participants with similar physical disabilities, the symptoms, needs, and experiences varied.  相似文献

We examined the association of joint trajectories of ethnic identity and criminal offending to psychosocial maturity, gang membership, and Mexican American affiliation among 300 Mexican American male juvenile offenders from ages 14 to 22. There were two low‐offending groups: one was the highest in ethnic identity and changing slightly with age and the other was the lowest in ethnic identity and stable with age. A third group displayed moderately declining offending and moderately stable ethnic identity. A fourth group displayed high‐offending individuals with moderate, but increasing, levels of ethnic identity, who were initially lower in psychosocial maturity and more likely to be gang members. The findings highlight the need to contextualize theories of ethnic identity development.  相似文献

Work-related musculoskeletal disorders (WRMD) are the result of the combination of different risk factors. They are very common among computer workers, mainly when neck and upper limbs are considered. Forty-two office workers from a public university participated in this study. They were divided into two groups: Symptomatic Subjects (SS, n=20) and Asymptomatic Subjects (AS, n=22), according to the Nordic Musculoskeletal Questionnaire (NMQ). Psychosocial indicators were assessed using the Job Content Questionnaire (JCQ) and Utrecht Work Engagement Scale (UWES). Workplaces were evaluated according to the Ergonomic Workplace Analysis (EWA), proposed by the Finnish Institute of Occupational Health. The NMQ showed higher weekly prevalence of complaints on neck, shoulders and wrist/hands (p=0.00) among SS. The annual prevalence of symptoms on wrist/hands was also higher among SS (p=0.02). The JCQ did not show any difference between groups (p>0.05). Higher proportion of servers with 'high level' of engagement, dedication and absorption, according to UWES, was identified among SS (p<0.01). EWA showed worse scores for 'Work Site', 'Job Content' and 'Repetitiveness of the Work' among SS (p<0.05). Servers are exposed to physical and psychosocial risk factors that can contribute to the development of WRMD. Work conditions need to be change in order to improve musculoskeletal health.  相似文献

We present a Bayesian approach to estimating a covariance matrix by using a prior that is a mixture over all decomposable graphs, with the probability of each graph size specified by the user and graphs of equal size assigned equal probability. Most previous approaches assume that all graphs are equally probable. We show empirically that the prior that assigns equal probability over graph sizes outperforms the prior that assigns equal probability over all graphs in more efficiently estimating the covariance matrix. The prior requires knowing the number of decomposable graphs for each graph size and we give a simulation method for estimating these counts. We also present a Markov chain Monte Carlo method for estimating the posterior distribution of the covariance matrix that is much more efficient than current methods. Both the prior and the simulation method to evaluate the prior apply generally to any decomposable graphical model.  相似文献

This paper is an account of a small scale exploratory study about the use and value of football metaphor as a device for facilitating therapeutic work. It is based on an evaluation which used a range of qualitative and quantitative approaches. In this paper, we selectively draw on the qualitative data to provide examples to inform our discussion. We illustrate various ways in which football metaphor can support therapeutic change: by aiding initial engagement, facilitating mutual support, enabling self-understanding and motivating change. We relate our analysis to the literature about the therapeutic value of metaphor and highlight the salience of using football metaphor in a group-based setting for men who are often seen as ‘hard to engage’ in therapeutic support. With some caveats, we argue that football metaphor offers a potentially rich and flexible therapeutic resource.  相似文献
