Workfare is, at least in part, a policy response to changing labour markets and the expansion taking place in jobs that are low‐paid, irregular and insecure. For lone mothers, increasingly the focus of workfare policies, precarious employment creates special challenges. However, the nature of the jobs that are available to women on social assistance has received relatively little attention in the workfare literature, which focuses more on individual characteristics, supports to employment, and programme impacts. Drawing upon both primary and secondary sources and using Ontario, the province with the most developed workfare programme in Canada, this article examines the ways in which policies support and enforce precarious employment. The article also considers the implications of precarious employment for UK policy, which has not (yet) adopted workfare for lone mothers, although incremental steps in that direction are taking place as employment is increasingly viewed as the appropriate objective of income support programmes for lone mothers. 相似文献

Do management tasks differ by field of practice? 总被引:1,自引:0,他引:1
The authors examine the question: Do management tasks differ by field of practice? Many social work Master's programs are organized on the principle of specialization by field of practice for both micro- and macro-practice students. Secondary analysis of task data suggests that managers and supervisors with MSW degrees perform the same task regardless of the field of practice. The study suggests a need to examine assumptions of current MSW curriculum organization. 相似文献

The technological approach to risk regulation seeks to lessen the incidence of mortality and morbidity by modifying environmental conditions. Insofar as risk-taking behavior is purposive, social scientists have predicted that technological progress may be negated by various forms of risk compensation. The validity of this hypothesis is tested in the transportation sector with data from the U.S. on the effects of new mandatory safety-belt-use laws. A fixed-effects model of traffic fatality counts is estimated using pooled data from 50 states during the 1975–1987 period. Results suggest that such laws have reduced mortality among car occupants to a degree that is compatible with the predictions of technologists. However, there is weak evidence of increased mortality among some nonoccupants, a pattern predicted by risk-compensation theorists. The lifesaving effects of belt-use laws are largest in states that permit primary police enforcement and appear to be somewhat larger for front-seat occupants age 21 and under. Although offsetting behavior appears to be small relative to lifesaving effects, it may take several more years for any compensatory behavior to achieve a new equilibrium.This research was supported in part by a grant from the Centers for Disease Control to the New England Injury Prevention Research Center. 相似文献

This article adopts a comparative perspective on policies to increase labour force participation of single mothers. Australia's orientation is briefly explored within the context of other major English-speaking countries (the United States, Britain and Canada), and the common emphasis in the policies on providing employment services and reducing poverty traps for Australia and Canada's largest province (Ontario) is then examined. While the potential of these approaches to increase labour force participation is found to be limited, the comparison suggests that Canada would do well to follow some of the recent anti-poverty measures Australia has adopted. Australia, however, appears to offer a less favourable employment climate for women. The article concludes that both jurisdictions will need to pursue a broader set of policies to respond to the root causes of poverty among women heading families on their own. 相似文献

This article describes an application of a method for assessing risks associated with the introduction of an organism into a new environment. The test organism was a binucleate Rhizoctonia fungal isolate that has potential for commercial development as a biological control agent for damping-off diseases in bedding plants. A test sample of host plant species was selected using the centrifugal phylogenetic host range principles, but with an emphasis on economic species. The effect of the fungus on the plant was measured for each species and expressed on a logarithmic scale. The effects on weights of shoots and roots per container were not normally distributed, nor were the effects on the number of plants standing (those which survived). Statements about the effect on the number standing and the shoot weight per container involved using the observed (empirical) distribution. This is illustrated with an example. Problems were encountered in defining the population of species at risk, and in deciding how this population should be formally sampled. The limitations of the method are discussed. 相似文献

Ethylene oxide is a gas produced in large quantities in the United States that is used primarily as a chemical intermediate in the production of ethylene glycol, propylene glycol, non-ionic surfactants, ethanolamines, glycol ethers, and other chemicals. It has been well established that ethylene oxide can induce cancer, genetic, reproductive and developmental, and acute health effects in animals. The U.S. Environmental Protection Agency is currently developing both a cancer potency factor and a reference concentration (RfC) for ethylene oxide. This study used the rich database on the reproductive and developmental effects of ethylene oxide to develop a probabilistic characterization of possible regulatory thresholds for ethylene oxide. This analysis was based on the standard regulatory approach for noncancer risk assessment, but involved several innovative elements, such as: (1) the use of advanced statistical methods to account for correlations in developmental outcomes among littermates and allow for simultaneous control of covariates (such as litter size); (2) the application of a probabilistic approach for characterizing the uncertainty in extrapolating the animal results to humans; and (3) the use of a quantitative approach to account for the variation in heterogeneity among the human population. This article presents several classes of results, including: (1) probabilistic characterizations of ED10s for two quantal reproductive outcomes-resorption and fetal death, (2) probabilistic characterizations of one developmental outcome-the dose expected to yield a 5% reduction in fetal (or pup) weight, (3) estimates of the RfCs that would result from using these values in the standard regulatory approach for noncancer risk assessment, and (4) a probabilistic characterization of the level of ethylene oxide exposure that would be expected to yield a 1/1,000 increase in the risk of reproductive or developmental outcomes in exposed human populations. 相似文献

The present report describes the organization and operation of a community based venereal disease clinic designed to meet the particular needs of homosexual men. Male same‐sex contact is seen as an important factor in the epidemiology of venereal disease and the community based clinic is described as a potentially important mechanism for control of the disease. Socio‐medical characteristics of male homosexual patients are described. Data are offered to document the prevalence of asymptomatic gonorrhea and the need for screening of atypical sites in this population. 相似文献

Abstract Although audio-visual materials are commonly used on college and university campuses, frequently those materials are not evaluated to determine what impact they may have on students' attitudes. The present research compared the effect of three audio-visual programs on attitudes of college students toward homosexuality. The three programs included a film that dealt with prejudice towards numerous groups but not towards homosexuals; a video-tape of a homosexual clergyman who discussed sexual variance with particular emphasis on homosexuality; and two films in which couples were explicitly engaging in homosexual behavior. A control group was used. All groups received a lecture about homosexuality. Using a two-way analysis of covariance, significant differences were found among the groups. Subjects that watched the film on prejudice and the video-tape of a discussion of homosexuality, as well as the control group, were all significantly more tolerant toward homosexuality than subjects who watched the explicit films. The difference among groups was immediate only. Five weeks after exposure to audio-visual programs, there were no significant differences. There was no significant difference between males and females, either immediately after seeing the programs or five weeks later. Thus, attitudes of college students toward homosexuality can be altered and were not gender specific. 相似文献

Rapid expansion of educational research and conceptualization combined with increased emphasis on relevance and effectiveness as values within the educational institution encourage expansion of the assumptions made by social work educators. Such expansion forces recognition of the complexity of the educational transaction and of the importance of flexibility as a teacher characteristic. But certain new assumptions suggest undeveloped opportunities for facilitating significant student learning. This article identifies four such opportunities based on assumptions about individual differences, cognitive functioning, and affective learning. A complex, growth-oriented view of social work education is emphasized. 相似文献
