Abstract We examine the prevalence of nonstandard employment in the nonmetropolitan United States using the Current Population Survey Supplement on Contingent Work (1999 and 2001). We find that nonstandard work is more prevalent in nonmetropolitan than in central city or suburban areas. Logistic regression models controlling for sociode‐mographic and work characteristics, show that nonmetropolitan workers experience higher odds of nonstandard employment than central city or suburban workers. Variations in industrial and occupational structures in nonmetro and metro areas do not explain residential differences in nonstandard work. We also estimate the odds of employment in each of the three components of nonstandard work: contingent work, part‐time, and varied hour work. Nonmetropolitan workers are more likely than central city and suburban workers to be employed in contingent or varied hour work. The benefits and wages of nonstandard work are lower than for standard work across residence areas. The results highlight the importance of understanding nonstandard work and the components of nonstandard work, particularly when considering the nature of work across industries, occupations, and residence.  相似文献

Cross-Cultural Supervision   总被引:1,自引:0,他引:1  
A multicultural perspective is essential in the twenty-first century. It is projected that by the year 2010 twelve of our most populous states will have significant minority populations. Thus, the supervision triad of patient, psychoanalyst, and supervisor will most likely contain persons of differing racial-ethnic backgrounds who are confronting problems and concerns in a diverse social environment. This paper uses examples to illustrate how this diverse triad is played out.  相似文献

Momentum and the growth-free segment of a population   总被引:1,自引:0,他引:1  
In the scenario of a sudden drop in fertility to replacement level. Preston (1986) argued that the population segment under age T, the length of generation, remained growth-free. Here we first present a new relationship for the momentum of any observed population as the ratio of 1) the proportion of the observed population under the mean age at childbearing to 2) the proportion of its life table population under that mean age. We then use that relationship to demonstrate Preston's approximation. Growth factors for other population segments are also presented. When the initial population is stable, momentum can be approximated as a function of the net reproduction rate alone.  相似文献

In the 1990s, the integrity and performance of nonprofit organizations in the United States have come increasingly under attack, and there are new calls to hold nonprofit organizations more accountable for their behavior and performance. This article reports on a study of the organizational structures of national nonprofit associations and asks how these umbrella organizations can help to self-regulate the sector through appropriate checks and balances between the national organization and local affiliates. The authors identify a number of differences in how associations with alternative structures hold local affiliates and national organizations responsible for their performances, and they conclude that structure is an avenue of self-regulation for nonprofit organizations deserving further attention.  相似文献

This paper proposes a Poisson‐based model that uses both error‐free data and error‐prone data subject to misclassification in the form of false‐negative and false‐positive counts. It derives maximum likelihood estimators (MLEs) for the Poisson rate parameter and the two misclassification parameters — the false‐negative parameter and the false‐positive parameter. It also derives expressions for the information matrix and the asymptotic variances of the MLE for the rate parameter, the MLE for the false‐positive parameter, and the MLE for the false‐negative parameter. Using these expressions the paper analyses the value of the fallible data. It studies characteristics of the new double‐sampling rate estimator via a simulation experiment and applies the new MLE estimators and confidence intervals to a real dataset.  相似文献

The authors consider a formulation of penalized likelihood regression that is sufficiently general to cover canonical and noncanonical links for exponential families as well as accelerated life models with censored survival data. They present an asymptotic analysis of convergence rates to justify a simple approach to the lower‐dimensional approximation of the estimates. Such an approximation allows for much faster numerical calculation, paving the way to the development of algorithms that scale well with large data sets.  相似文献

Partant de l'approche culturelle de l'analyse des sous-cultures observées chez les jeunes, cette enquête sur le terrain menée dans une ville de l'Ouest canadien examine les significations que nos sujets accordent à leur appartenance à un sous-groupe de skinheads qui se veut apolitique. Notre étude remet en cause une certaine image que l'on se fait du mouvement skinhead. En dépit des idées reçues qui véhiculent une apparente homogénéité, notre recherche montre que la sous-culture skinhead est à la fois complexe et multidimensionnelle et qu'elle offre à ses membres un choix de modèles de comportements et d'orientations idéologiques, même s'ils sont souvent contradictoires. Notre analyse suggèe aussi que, loin d'être profondément contestataires ou révolutionnaires, les groupes de skinheads peuvent constituer un instrument de reproduction des rapports sociaux, en particulier les rapports entre les sexes, les groupes raciaux et les ethnies. Grounded in a cultural studies approach to youth subcultures and based on participant observation in a Western Canadian city, this study examines the meanings associated with membership for participants in a self-described “non-political” branch of the skinhead subculture. Despite popular images that imply homogeneity, the study shows that the skinhead subculture is both complex and multi-dimensional and that it accommodates, albeit in often contradictory ways, a range of behavioural and ideological opportunities for its members. The study also suggests that, far from being resistant or transformative in any significant way, skinhead groups may represent a vehicle for social reproduction, specifically with respect to gender, race and ethnicity.  相似文献
