Between 1990 and 2007, the number of Catholic schools in the United States decreased by 14% and enrollment diminished by 7%. We generate two measures of publicity of sexual abuse at the diocesan level—public disclosure and news coverage. Dioceses with higher rates of negative publicity had a larger decline in both the number of Catholic schools and overall Catholic school enrollment. We estimate that publicity arising from sexual offenders within the Church explains 5% of the decline in the availability of Catholic schooling. (JEL I21, H52, H44)  相似文献

Donor imputation is frequently used in surveys. However, very few variance estimation methods that take into account donor imputation have been developed in the literature. This is particularly true for surveys with high sampling fractions using nearest donor imputation, often called nearest‐neighbour imputation. In this paper, the authors develop a variance estimator for donor imputation based on the assumption that the imputed estimator of a domain total is approximately unbiased under an imputation model; that is, a model for the variable requiring imputation. Their variance estimator is valid, irrespective of the magnitude of the sampling fractions and the complexity of the donor imputation method, provided that the imputation model mean and variance are accurately estimated. They evaluate its performance in a simulation study and show that nonparametric estimation of the model mean and variance via smoothing splines brings robustness with respect to imputation model misspecifications. They also apply their variance estimator to real survey data when nearest‐neighbour imputation has been used to fill in the missing values.

This article examines how the social and political contexts in receiving countries affect the transnational political practices of migrants and refugees, such as their mobilization around political events in their homeland. The case study explores the political participation of Turks and Kurds in Germany and the Netherlands in its full complexity, that is in both the immigration country and in homeland politics. The findings suggest that transnational political practices should not be reduced to a function of the political opportunity structures of particular receiving countries for two main reasons: (a) more inclusive political structures, which provide for more participation and co‐operation on immigrant political issues, may at the same time, and for that very reason, serve to exclude dialogue on homeland politics; (b) homeland political movements may draw on a different range of resources than their immigrant political counterparts, including those outside the local political institutional context.  相似文献

Wang KY‐T, Wong C‐k, Tang K‐L. Citizens' attitudes towards economic insecurity and government after the 2007 financial tsunami: A Hong Kong and Taiwan comparison The purpose of this study was to investigate people's attitudes to economic insecurity and government in Hong Kong and Taiwan after the financial tsunami of 2007. Random sampling telephone surveys were conducted in July 2009. These are the main conclusions: First, the most vulnerable groups hurt by the financial crisis were low‐income families and people who had lost their job or were afraid of losing it. This implies that the old policy issue of social stratification and the emerging policy issue of employment insecurity coexisted during the financial crisis. Second, personal experiences of economic insecurity had an influence on people's perceptions of the severity of the economic crisis at the societal level. Third, citizens had ambivalent feelings about public interventions during the crisis. Fourth, there were both convergence and divergence between Hong Kong and Taiwan with regard to attitudes to particular issues. The policy implications of these findings are discussed in the final section of this article.  相似文献

In pest risk assessment it is frequently necessary to make management decisions regarding emerging threats under severe uncertainty. Although risk maps provide useful decision support for invasive alien species, they rarely address knowledge gaps associated with the underlying risk model or how they may change the risk estimates. Failure to recognize uncertainty leads to risk‐ignorant decisions and miscalculation of expected impacts as well as the costs required to minimize these impacts. Here we use the information gap concept to evaluate the robustness of risk maps to uncertainties in key assumptions about an invading organism. We generate risk maps with a spatial model of invasion that simulates potential entries of an invasive pest via international marine shipments, their spread through a landscape, and establishment on a susceptible host. In particular, we focus on the question of how much uncertainty in risk model assumptions can be tolerated before the risk map loses its value. We outline this approach with an example of a forest pest recently detected in North America, Sirex noctilio Fabricius. The results provide a spatial representation of the robustness of predictions of S. noctilio invasion risk to uncertainty and show major geographic hotspots where the consideration of uncertainty in model parameters may change management decisions about a new invasive pest. We then illustrate how the dependency between the extent of uncertainties and the degree of robustness of a risk map can be used to select a surveillance network design that is most robust to knowledge gaps about the pest.  相似文献

Decentralisation offers significant opportunities to improve government accountability by exerting stronger pressures both from below (demand) and above (supply). The literature contains many examples, however, where the potential has not been realised, partly because decentralisation reforms have often been introduced without thinking through their accountability implications. Even when accountability is taken into account, the efforts tend to emphasise either the supply or the demand side of the equation, but not both. Drawing on the sets of literature on fiscal, administrative and political decentralisation, this article presents a methodology for studying this.  相似文献

We present findings from an anthropological field study on the role of language and language policy in migration from Poland to Norway, and the larger implications for emerging language and immigration policy in Europe. Initial fieldwork in Norway found that Polish workers without knowledge of the Norwegian language struggled to secure employment in the formal economy. The 2008 financial crisis intensified competition in the labour market and underscored fluency in Norwegian as a means of discriminating among workers. Comparative case studies of language schools revealed that these organizations are active participants in channeling Polish migrants' movements into a segmented labour market, often in ways that involve cooperation between private companies and the State. We frame the Norwegian case within the larger context of Europe and the trend there toward favoring integration over multiculturalism. The emergence of restrictive language policies in Europe may be interpreted as a legally and culturally acceptable means for discouraging access to rights associated with permanent residency or citizenship by work migrants from CEE countries, while at the same time permitting them access to the labour market for temporary work. The long‐term consequences of such policies for European society are uncertain.  相似文献

This study integrates the results of quantitative and qualitative methods to elucidate the association between sexual identity and physical and sexual abuse among Puerto Rican drug users. A structured questionnaire was administered to 800 subjects in New York and 399 in Puerto Rico. A total of 93 subjects (7.9%) self‐identified as homosexual or bisexual. Gay males were significantly more likely than heterosexual males to report first occurrence of physical abuse by a family member in childhood. Both gay and bisexual males were more likely than their heterosexual counterparts to report first experiencing unwanted sex in childhood and intimate partner physical abuse later in life. Lesbians were more likely than female heterosexuals to report unwanted sex in childhood. Qualitative data were collected through in‐depth life histories with 21 subjects and suggest that gay and lesbian subjects perceive antihomosexual prejudice on the part of family members as one cause of childhood physical and sexual abuse.  相似文献
