The lack of comparison groups is a common problem for researchers conducting evaluations of small, specialized programs. When conventional comparison groups are not available, the authors suggest a possible alternative approach which involves: (a) locating a sub-group in a national study for whom relevant variables have been measured; (b) generating a statistical model which predicts the outcome of interest in the national data; and (c) applying the predictive model to program data, in order to estimate outcomes in the absence of progam intervention. The authors illustrate this new application by presenting the results of an analysis of data from Project Talent, a national manpower study, and discuss its application to the evaluation of a medical training program in New York City. 相似文献

This paper proposes a model for assessing potential parents, based on our research and practice in which we examined current methods of assessment in the light of anti-oppressive principles and methods. We participated in and observed the work of two differing fostering and adoption agencies, and have drawn from our experiences and analysis to produce a pattern for assessment which critically draws on best practices. The paper also draws on previously published papers which discuss theories of research and assessment (Clifford 1992–93; Clifford 1994; Clifford 1995; Clifford & Cropper 1994), and draws a parallel between the processes of research and those of assessment. Our view is that research methods provide a foundation for assessment methods in various ways, mutually illuminating oppressive and anti-oppressive processes. 相似文献

Abstract This non-refereed contribution to Human Resource Development International represents the reflections of three US delegates who attended the 6th International Conference on HRD Research and Practice across Europe in Leeds, England, in May 2005. We begin by providing an overview of the conference programme, examine the conference theme as reflected in the scholarship presented at the conference and share our impressions of the conference atmosphere. We conclude with some final thoughts. 相似文献

The paper analyses the impact of foreign workers on the Italian labour market. We address the issue of whether immigrants from less developed countries are complementary or substitutes to domestic workers. We construct a data set on immigrant workers from the Administrative Social Security Archive which starts in 1986, before the general amnesty of 1990–91, when a large share of illegal immigrants were granted working permits, and end in 1995. A two-stage procedure devised by Moulton is applied to yearly cross-sections of wages by industry and region. Our results show that the inflow of immigrants raises the wages of native manual workers (i.e. it has a complementary effect), and this effect is larger in small firms and in the north of the country. We postulate that the positive impact on native wages is due to the existence of labour constraints on the side of firms. Firms are unable to expand their output because they cannot find native workers who are willing to undertake certain (typically low-skilled) jobs. Immigrants help to fill this gap. This view is reinforced by the fact that over a ‘crucial threshold’ of the share of foreign work (7.7–12 percent) additional inflows in the labour market of foreign work have a negative effect on native wages (i.e. they compete with natives). 相似文献

Impacts of collaboration and network indicators on patent quality: The case of Canadian nanotechnology innovation 总被引:1,自引:0,他引:1
This article studies the impact of collaboration and co-inventorship network characteristics of Canadian nanotechnology inventors on the quality of their inventions. We investigate the impact of four types of variables on patent quality, using the number of claims as a proxy for quality: (a) the presence of highly central inventors; (b) the presence of star inventors; (c) repeated collaboration; (d) international collaboration. We show that the presence of more central inventors and of stars in the research team has a positive influence on patent quality, while repeated collaboration has a negative impact. Patents owned by foreign organisations, controlling for whether assignees are firm, yields patents of higher quality. 相似文献

As part of the National College Grief Study, college student bereavement experience was examined specifically in a Christian university climate. Sex, year in school, and closeness to the deceased were measured in terms of academic and mental health outcomes and resources utilized. Females reported more mental health problems when close to the deceased, and seniors were less likely than first year students to utilize personal support resources of family and religion. During close losses, students experienced more mental health problems and negative social outcomes, but they did not access more resources. Recommendations for university personnel and suggestions for further research are given. 相似文献

This paper analyzes the effect of product market regulation (PMR) on unemployment in a search model with heterogeneous multiple‐worker firms. In our setup, PMR modifies the distribution of firm productivities, thereby affecting the equilibrium rate of unemployment. We distinguish between PMR related to entry costs and PMR that generates recurrent fixed costs. We find that: (i) higher entry costs raise the rate of unemployment mainly through our novel selection effect, (ii) higher fixed costs decrease unemployment through the selection effect and increase it through the competition effect analyzed in Blanchard and Giavazzi (2003, Quarterly Journal of Economics, 118, 879–907). Firm heterogeneity magnifies the impact of both types of regulatory costs. We propose econometric evidence consistent with the unemployment effects of sunk versus recurring costs. 相似文献

Financial accounting research increasingly includes business model (BM) constructs, but the ability of financial reporting to capture BM characteristics has not been verified. This study empirically explores the links between BMs and accounting choices by clustering a sample of 103 European listed companies according to an innovative, nonlinear algorithm (self-organizing map) that uses pertinent industrial, strategic, governance, and financial variables to uncover different dimensions of a BM. The authors investigate accounting choices (accounting measurement, accounting treatment, and disclosure level) by companies that belong to the different identified BMs. The analysis of the relations between different company BMs and their accounting choices indicates no significant connections, which offers empirical confirmation of the criticisms regarding the inability of financial reporting to represent (or even consider) a company’s BM. The results suggest further attempt to capture BM in financial reporting, which requires regulators to establish accounting standards that acknowledge the value creation processes of an entity and incentivize managers to represent those processes. 相似文献

AbstractObjective: A Haddon Matrix analysis was used to systematically review literature evaluating college campus sexual assault prevention programs to identify research gaps and intervention opportunities. Methods: Articles included were published from January 1, 2001 to December 31, 2017; indexed in PubMed, PsycInfo, or Scopus; involving English-speaking undergraduate students in the US; with experimental or quasi-experimental design. Results: All 31 eligible studies evaluated educational programing; all relied on self-report measures; and three-quarters had follow-up periods ≤ 6?months. Significant positive effects were reported by 6 of 10 studies that measured bystander behavior, 6 of 10 that educated potential victims and assessed victimization, and one of four that educated potential perpetrators and measured perpetration. Conclusion: The Haddon Matrix analysis identified the need for interventions that address perpetrators and the post-assault period, as well as studies of the impact of enforcing existing policies and new environmental and situational approaches to sexual assault prevention. 相似文献

Under what conditions does one find a new home via one's social network? Does the way in which a house is acquired affect how satisfied one is with the house? We formulate hypotheses on the characteristics of personal networks, the context of the move and their effect on those who attain a house through informal channels and how satisfied they are with the new home. We use a representative dataset from the Netherlands (the Survey of the Social Networks of the Dutch, SSND, n = 1007) to test our arguments. Our results show that buyers with more diverse social networks and renters with larger social networks are more likely to find their home via social contacts. However, finding a home through an informal channel does not enhance their satisfaction with the house that is found. 相似文献
