A comparative analysis of public sector restructuring in the U.S., Canada, Mexico, and the Caribbean
We examine public sector restructuring in North America and selected Commonwealth Caribbean nations. Although all the countries
studied experienced significant restruc-turing in response to public debt pressures, there were major differences across coun-tries
in the magnitude, pace, form, and the manner in which restructuring decisions were made. These differences reflect the state
of economic development and institu-tional characteristics, e.g., the role of the state and the industrial relations system.
In developing countries, international lending institutions played a major role in trans-forming the role of the state. In
developed countries, the inherent stability of the eco-nomic systems and institutional pressures led to a gradualist approach
to restructuring. 相似文献

Mahjong is a popular gambling game played in Chinese communities all over the world (Papineau, China Perspect 28:29–42, 2000) and is sometimes referred to as ‘国赌’ (guodu, the Chinese national gambling game) or ‘修长城’ (xiu changcheng, repairing the Great Wall). Exploratory studies using snowball sampling conducted by Zheng et al. (J Psychol Chin Soc 9(2):241–262,
2008) indicated that Mahjong is not only a popular pastime within the Sydney Chinese community but also problematic for around
3% of players. The current study aimed to extend earlier studies by estimating the prevalence of Mahjong problem gambling
in a random sample of Sydney Chinese community members. In addition, due to first-hand gambling experience of the first author
with superstitious Mahjong players, the study also investigated the role of superstitious beliefs in Mahjong gambling. The
current study involved a series of self-report questionnaires administered to 469 randomly selected Chinese Australians in
Sydney. The problem gambling rate, assessed by the Canadian Problem Gambling Index (CPGI), was 3.8%, with Chinese males and
older Chinese prominent. Superstitious beliefs were found to play a part in the maintenance of Mahjong gambling behaviour.
Information stemming from the current study has helped gain insight into culturally specific forms of gambling, and to identify
correlates of problem gamblers. Funding bodies and counselling services should be aware of the existence of this form of gambling,
and should devise appropriate treatment plans for Mahjong problem gamblers. 相似文献

With the conducted Delphi study diverse alternatives could be identified which have been used by Consultants in dealing with their own unawareness. Superior strategies, which controlled the adoption of individual steps and oriented the activities in dealing with unawareness, as well as organisational regulations for dealing with unawareness, were noticeable, which could be adopted depending on the subjective perception and assessment of the present unawareness and its relevance and impacts. The detected strategies ranged from the maintenance and use of unawareness to open communication and elimination of unawareness to total ignorance and the hiding of unawareness. Concerning organisational regulations, on the one hand formal regulations and on the other hand informal regulations could be found. 相似文献

The area under the receiver operating characteristic curve (AUC) is the most commonly reported measure of discrimination for prediction models with binary outcomes. However, recently it has been criticized for its inability to increase when important risk factors are added to a baseline model with good discrimination. This has led to the claim that the reliance on the AUC as a measure of discrimination may miss important improvements in clinical performance of risk prediction rules derived from a baseline model. In this paper we investigate this claim by relating the AUC to measures of clinical performance based on sensitivity and specificity under the assumption of multivariate normality. The behavior of the AUC is contrasted with that of discrimination slope. We show that unless rules with very good specificity are desired, the change in the AUC does an adequate job as a predictor of the change in measures of clinical performance. However, stronger or more numerous predictors are needed to achieve the same increment in the AUC for baseline models with good versus poor discrimination. When excellent specificity is desired, our results suggest that the discrimination slope might be a better measure of model improvement than AUC. The theoretical results are illustrated using a Framingham Heart Study example of a model for predicting the 10-year incidence of atrial fibrillation. 相似文献

Abstract The movement for vocational education conceals within itself two mighty and opposing forces, one which would utilize the public school primarily to turn out more efficient laborers in the present economic regime, with certain incidental advantages to themselves, the other which would utilize all the resources of public education to equip individuals to control their own future economic careers, and thus help on such a reorganization of industry as will change it from a feudalistic to a democratic order.

In a longitudinal investigation of the antecedents and pathways of teen parenthood, 475 participants (248 females and 227 males) were followed from Grade 7 through early adulthood. In the first year of the investigation, homogeneous subgroups were identified by clustering participants on five characteristics (i.e., aggression, popularity, academic competence, age, and socioeconomic status). At the same time, peer social networks were identified by the Social Cognitive Map procedure. For each participant, the configuration of peer characteristics was also identified. A high correspondence was found between the individual characteristics and the characteristics of closely affiliated peers. Both teen fatherhood and teen motherhood were predicted by individual configurations and peer configurations (e.g., a combination of high aggression, low academic competence, low popularity, and low family SES). Peer characteristics, race, and family socioeconomic status assumed unique roles in predicting teen motherhood. Growth curve analyses showed that teen-mothers differed from non-mothers in their starting points and developmental trajectories. This study demonstrated that a simultaneous examination of both the individual and his/her peer context yielded important information on teen parenthood. 相似文献

While union density in the public sector has increased in recent decades, private sector union density in the U.S. has declined steadily since the mid-1950s. Scholars have evoked a variety of explanations to account for the decline in union membership, but substantially less attention has been devoted to understanding the contribution of the union organizing process as governed by the National Labor Relations Board (NLRB). In this paper, we focus on two aspects of this process: union organizing effort (the effort to establish union representation elections to organize non-unionized workers) and union organizing success (success in winning union representation elections). Using annual time series data for the U.S. from 1948 to 2004, we show that there has been a long-term decline in both union organizing effort and union organizing success, which likely contributes to declining union density. We focus on three explanations for these changes: the political–legal environment for unions, deindustrialization and globalization, and employer opposition to unionization efforts. We find that each of these factors contributes to organizing effort and success and conclude with a discussion of the implications of this research for future mobilization efforts. 相似文献
