Service workers' responses to abuse of the elderly

The social service providers and physicians who encounter elder abuse have several potential avenues of intervention open to them in helping the elderly. Practice and training issues are discussed that are relevant for improving interventions and referrals in cases of family abuse of the elderly.     

Bayesian analysis of directed graphs data with applications to social networks

Summary.  A fully Bayesian analysis of directed graphs, with particular emphasis on applica- tions in social networks, is explored. The model is capable of incorporating the effects of covariates, within and between block ties and multiple responses. Inference is straightforward by using software that is based on Markov chain Monte Carlo methods. Examples are provided which highlight the variety of data sets that can be entertained and the ease with which they can be analysed.     

A class of symmetric bivariate uniform distributions

A class of symmetric bivariate uniform distributions is proposed for use in statistical modeling. The distributions may be constructed to be absolutely continuous with correlations as close to±1 as desired. Expressions for the correlations, regressions and copulas are found. An extension to three dimensions is proposed.     

Useful relationship between the log-survival function and truncated moments,with applications

We present a new characterization technique extracted from a well known idea in statistical inference. We use the partial derivative of the logarithm of the survival function in connection with truncated moments to characterize several probability distributions. Our methods introduce a unified technique to obtain several well known results in a unified way.     

Merging data from multiple sources: pretest and shrinkage perspectives

In this article, we have developed asymptotic theory for the simultaneous estimation of the k means of arbitrary populations under the common mean hypothesis and further assuming that corresponding population variances are unknown and unequal. The unrestricted estimator, the Graybill-Deal-type restricted estimator, the preliminary test, and the Stein-type shrinkage estimators are suggested. A large sample test statistic is also proposed as a pretest for testing the common mean hypothesis. Under the sequence of local alternatives and squared error loss, we have compared the asymptotic properties of the estimators by means of asymptotic distributional quadratic bias and risk. Comprehensive Monte-Carlo simulation experiments were conducted to study the relative risk performance of the estimators with reference to the unrestricted estimator in finite samples. Two real-data examples are also furnished to illustrate the application of the suggested estimation strategies.     

Subjective Happiness of Lebanese College Youth in Lebanon: Factorial Structure and Invariance of the Arabic Subjective Happiness Scale

The present study evaluated the subjective happiness of Lebanese college youth using a multi-item rather than a single-item subjective happiness measure. An Arabic translation of the Subjective Happiness Scale (SHS) was administered to 273 Lebanese college youth from state- and private-run higher institutions of learning, as was the Arabic Adult Parental Acceptance-Rejection Questionnaire (Arabic PARQ). The reliability and validity of the Arabic SHS was tested in terms of factor analysis, internal consistency, and correlation with Arabic PARQ scores, as was the factorial invariance and relation of the scale across age, sex, marital status, birth order, and college campus. The Arabic SHS showed a reliable unitary structure similar to those found in other cultures, and factorial invariance across sex, marital status, birth order and college campus. While age, sex, marital status and birth order were independent of happiness scores, college students attending the private university reported greater happiness than those from the state-run academic setting. It was concluded that the Lebanese Arabic SHS is a reliable and valid measure of global subjective happiness, its factor structure is similar across other translated versions of the scale, and its scores are independent of age, sex, marital status and birth order.     

Developing a Broadly Applicable Measure of Risk Perception

Decades of research identify risk perception as a largely intuitive and affective construct, in contrast to the more deliberative assessments of probability and consequences that form the foundation of risk assessment. However, a review of the literature reveals that many of the risk perception measures employed in survey research with human subjects are either generic in nature, not capturing any particular affective, probabilistic, or consequential dimension of risk; or focused solely on judgments of probability. The goal of this research was to assess a multidimensional measure of risk perception across multiple hazards to identify a measure that will be broadly useful for assessing perceived risk moving forward. Our results support the idea of risk perception being multidimensional, but largely a function of individual affective reactions to the hazard. We also find that our measure of risk perception holds across multiple types of hazards, ranging from those that are behavioral in nature (e.g., health and safety behaviors), to those that are technological (e.g., pollution), or natural (e.g., extreme weather). We suggest that a general, unidimensional measure of risk may accurately capture one's perception of the severity of the consequences, and the discrete emotions that are felt in response to those potential consequences. However, such a measure is not likely to capture the perceived probability of experiencing the outcomes, nor will it be as useful at understanding one's motivation to take mitigation action.     

The Australian model of immigration and multiculturalism: is it applicable to Europe?

"The aim of this article is to examine the experience of Australia with regard to immigration and ethnic diversity since 1945, and to discuss the relevance of this experience for Western Europe." The author finds that "since 1945, over 5 million settlers have come from many different countries, leading to a situation of great cultural diversity.... Over the last twenty years, a policy of multiculturalism has emerged, giving rise to several special institutions. This has had profound effects both on social policy and on concepts of national identity. The relevance of the Australian model for Western Europe is discussed."
