This article discusses the unequal impact of Covid-19 on the lives of the children of survivors of modern slavery, child victims of exploitation and children at risk of exploitation in the UK. It draws on research that has analysed the risks and impacts of Covid-19 on victims and survivors of modern slavery. It explores how pandemic responses may have hindered these children's rights to education, food, safety, development and participation and representation in legal processes. It suggests that the pandemic should be used as an impetus to address inequalities that existed pre-Covid-19 and those that have been exacerbated by it.  相似文献

We propose a mixture of latent variables model for the model-based clustering, classification, and discriminant analysis of data comprising variables with mixed type. This approach is a generalization of latent variable analysis, and model fitting is carried out within the expectation-maximization framework. Our approach is outlined and a simulation study conducted to illustrate the effect of sample size and noise on the standard errors and the recovery probabilities for the number of groups. Our modelling methodology is then applied to two real data sets and their clustering and classification performance is discussed. We conclude with discussion and suggestions for future work.  相似文献

This article illustrates the challenges of creating a faculty development program on technology through the presentation of experiences with one such program, the Virtual Guild. Using examples from the Virtual Guild, the authors focus on the areas of program design and faculty motivation. The discussion of program design involves selecting content and determining the program format. Motivational issues discussed include individual- and organizational-level factors, as well as the combined effect of these factors on faculty participation.  相似文献

This paper studies long-term private health insurance (PHI) in Germany. It describes the main actuarial principles of premium calculation and relates these to existing theory. In the German PHI policyholders do not commit to renewing their insurance contracts, but insurers commit to offering renewal at a premium rate that does not reflect revealed future information about the insured risk. We show that empirical results are consistent with theoretical predictions from one-sided commitment models: front-loading in premiums generates a lock-in of consumers, and more front-loading is generally associated with lower rates of lapse. Due to a lack of consumer commitment, dynamic information revelation about risk type implies that high-risk policyholders are more likely to retain their PHI contracts than are low-risk types.  相似文献

The survey at hand uses a sophisticated classification between derivative and original founders to demonstrate that the group of entrepreneurs consists of several distinct sub-groups or types. With the help of personality traits (Big Five) we examine the different entrepreneurial types. We also investigate how the interaction of personality and entrepreneurial type influences success. The analyses were conducted with a sample of franchise founders (derivative founders) and new business founders (original founders) in Germany. The results in relation to the entrepreneurial type support the distinction between groups as differences were found in personality traits. With respect to the prediction of success we identify interaction effects between personality and entrepreneurial type.  相似文献

This paper investigates the effects of government spending on private consumption and investment in the European Union (EU). A certain consensus has been reached on the expansionary Keynesian effects of fiscal impulses on the economic activity. However, the existing empirical literature has concentrated on few countries, mostly outside the EU. We check the validity of this result for the EU area using annual data and a panel vector auto-regression approach, with particular attention being paid to robustness across alternative identification assumptions based on Cholesky orderings. Our results show that shocks to public spending positively affect private consumption and investment. According to our baseline estimate, a 1% increase in public current expenditure produces a 0.24% impact rise in private consumption, and a 0.41% impact rise in private investment. The effects are substantial, and die out slowly in the case of private consumption (the cumulative impact amounts to +0.56% after 3 years), but much faster in the case of private investment. A further disaggregation between wage and non-wage components reveals that public salaries have a relatively stronger stimulating role. This is not due to the different weights on GDP of the two components, which have comparable values in our sample.  相似文献

The organized camp experience has been an important part of the lives of children, youth, and adults for over 150 years. The camp experience is a way for young people to explore and search for an authenticity often missing in other parts of their lives that contributes to their healthy transition into adulthood. Over the past decade, tremendous growth in the volume and rigor of camp-related research has occurred, facilitated by a targeted research agenda conducted by the American Camp Association. This agenda was founded on three national research projects conducted between 2003 and 2007: a study to identify the developmental outcomes of the camp experience, a benchmarking study of the youth development supports and opportunities provided through camp experiences, and a program improvement project directed toward enhancing supports and opportunities provided by camps. The findings from these research projects suggest that camp experiences promote developmental outcomes in both campers and staff and that camps provide the supports and opportunities needed for positive youth development. This article explores the developmental outcomes of the camp experience and the characteristics of the supports and opportunities afforded by camp experiences, including settings, structures, and programs and activities, as a way to provide a clearer understanding of camp as a positive youth development setting. Innovations and opportunities in research related to the provision of quality camp experiences are also considered.  相似文献
