This paper studies the processes through which skilled international workers are differentially attracted to and incorporated in the rapidly globalising cities of Dubai and Abu Dhabi, thereby reproducing the migrant division of labour in these cities. This is accomplished by presenting results from a large-scale employment survey of foreign and local firms in these cities, as well as key informant interviews conducted with representatives of these firms. Most significantly, it is in global city labour markets that firm employment practices intersect with state regulatory frameworks and local employment structures, and thus, where skilled international migration flows are localised. 相似文献

The present Monte Carlo simulation study adds to the literature by analyzing parameter bias, rates of Type I and Type II error, and variance inflation factor (VIF) values produced under various multicollinearity conditions by multiple regressions with two, four, and six predictors. Findings indicate multicollinearity is unrelated to Type I error, but increases Type II error. Investigation of bias suggests that multicollinearity increases the variability in parameter bias, while leading to overall underestimation of parameters. Collinearity also increases VIF. In the case of all diagnostics however, increasing the number of predictors interacts with multicollinearity to compound observed problems. 相似文献

Abstract. The use of automated external defibrillators (AEDs) increases survival in cardiac arrest events. Due to the success of previous efforts and free, readily available mobile mapping software, the discussion is to emphasize the importance of the use of AEDs to prevent sudden cardiac arrest–related deaths on college campuses and abroad, while suggesting a novel approach to aiding in access and awareness issues. A user-friendly mobile application (a low-cost iOS map) was developed at Florida State University to decrease AED retrieval distance and time. The development of mobile AED maps is feasible for a variety of universities and other entities, with the potential to save lives. Just having AEDs installed is not enough—they need to be easily locatable. Society increasingly relies on phones to provide information, and there are opportunities to use mobile technology to locate and share information about relevant emergency devices; these should be incorporated into the chain of survival. 相似文献

ABSTRACTObjective: To evaluate a text message (SMS) program as a booster to an in-person alcohol intervention with mandated college students. Participants: Undergraduates (N = 224; 46% female) who violated an on-campus alcohol policy over a 2-semester period in 2014. Methods: The SMS program sent drinking-related queries each Thursday and Sunday and provided tailored feedback for 6 weeks. Response rates to SMS drinking-related queries and the associations between weekend drinking plans, drinking-limit goal commitment, and alcohol consumption were examined. Gender differences were explored. Results: Ninety percent of SMS queries were completed. Weekend binge drinking decreased over 6 weeks, and drinking-limit goal commitment was associated with less alcohol consumption. Compared with women, men had greater reductions in alcohol consumption when they committed to a drinking-limit goal. Conclusions: Preliminary evidence suggests that an SMS program could be useful as a booster for helping mandated students reduce weekend binge drinking. 相似文献

AbstractLinear mixed effects models have been popular in small area estimation problems for modeling survey data when the sample size in one or more areas is too small for reliable inference. However, when the data are restricted to a bounded interval, the linear model may be inappropriate, particularly if the data are near the boundary. Nonlinear sampling models are becoming increasingly popular for small area estimation problems when the normal model is inadequate. This paper studies the use of a beta distribution as an alternative to the normal distribution as a sampling model for survey estimates of proportions which take values in (0, 1). Inference for small area proportions based on the posterior distribution of a beta regression model ensures that point estimates and credible intervals take values in (0, 1). Properties of a hierarchical Bayesian small area model with a beta sampling distribution and logistic link function are presented and compared to those of the linear mixed effect model. Propriety of the posterior distribution using certain noninformative priors is shown, and behavior of the posterior mean as a function of the sampling variance and the model variance is described. An example using 2010 Small Area Income and Poverty Estimates (SAIPE) data is given, and a numerical example studying small sample properties of the model is presented. 相似文献

Scholars in the field of management and culture have developed paradigms regarding the importance of managing people across culture. While most scholars agree that culture plays a vital role in an organization, it has been recognized that research on the sub-cultures within a national culture that impact on an organization, is very limited. One example is the impact of Javanese culture in Indonesian organizations' environments. Indonesia is widely known as a multicultural country, with a population made up of people from approximately 364 ethnicities. Of these ethnicities, the Javanese have come to be recognized over time as the most culturally and politically dominant in Indonesia. The exploration of Javanese culture and its development over time are the central concerns of this article. The values central to Javanese culture are identified and the relationship between these values and Western perspectives of management practices such as communication, change management, and conflict management are discussed. 相似文献

Much of the empirical literature on intergenerational child maltreatment focuses on the mechanisms that explain how maltreatment is transmitted across generations. Few studies have examined child protective service outcomes associated with intergenerational families. The current study addresses this gap in the literature. This study compares 1196 caregivers, most of whom are single African American females, and 2143 children from first and second generation child welfare-involved families. All families have a history of substance abuse. We sought to understand how first and second generation families differ with regard to social and economic status indicators, as well as whether intergenerational child welfare involvement is associated with permanency outcomes. Our findings indicate that second generation families experience significantly more risk factors at the time of case opening, and are two-thirds as likely to be reunified as compared with first generation families. The singular effects of generation status disappeared, however, once the interaction between mental health diagnosis and second generation status was entered into the model, suggesting that it is not just being intergenerationally involved in the child welfare system that reduces the chance of reunification, but rather second generation caregivers have more mental health problems that are associated with a lower likelihood of reunification. 相似文献

The aims of this study were to develop scales to assess experiences of sexually abused children in the Irish criminal justice system (CJS); identify aspects of the CJS which children experience as negative; compare the perceptions of children, parents and professionals of sexually abused children's experiences of the CJS; and determine correlations between perceptions of children's CJS experiences and current psychological adjustment. Forty‐three children, 101 parents, 32 mental health professionals, 27 police officers and 21 lawyers completed parallel versions of the Criminal Justice System Questionnaire (CJSQ) which assessed satisfaction with aspects of the CJS relevant to sexually abused children, specifically: Gardaí (police), medical examination, Director of Public Prosecutions, waiting for court, court professionals, court context and the CJS. Fifteen scales were developed by conducting principal component analyses. Children gave negative ratings on nine of these, and on seven children, parents and professionals differed in their perceptions of how children experienced the CJS with mental health professionals viewing the impact of the CJS as more problematic than parents and children. Scores of children and parents on CJSQ scales correlated with indices of current psychological adjustment. These results point to the importance of making the Irish CJS more child‐friendly and for evaluating these reforms with the CJSQ. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

This study considers a supply chain with two heterogeneous suppliers and a common retailer whose type is either low‐volume or high‐volume. The retailer's type is unknown to the suppliers. The flexible supplier has a high variable cost and a low fixed cost, while the efficient supplier has a low variable cost and a high fixed cost. Each supplier offers the retailer a menu of contracts. The retailer chooses the contract that maximizes its expected profit. For this setting, we characterize the equilibrium contract menus offered by the suppliers to the retailer. We find that the equilibrium contract menus depend on which supplier–retailer match can generate the highest supply chain profit and on how much information rent the supplier may need to pay. An important feature of the equilibrium contract menus is that the contract assigned to the more profitable retailer will coordinate the supply chain, while the contract assigned to the less profitable retailer may not. In addition, in some circumstances, the flexible supplier may choose not to serve the high‐volume retailer, in order to avoid excessive information rent. 相似文献
