Asymptotic Properties and Variance Estimators of the M-quantile Regression Coefficients Estimators

M-quantile regression is defined as a “quantile-like” generalization of robust regression based on influence functions. This article outlines asymptotic properties for the M-quantile regression coefficients estimators in the case of i.i.d. data with stochastic regressors, paying attention to adjustments due to the first-step scale estimation. A variance estimator of the M-quantile regression coefficients based on the sandwich approach is proposed. Empirical results show that this estimator appears to perform well under different simulated scenarios. The sandwich estimator is applied in the small area estimation context for the estimation of the mean squared error of an estimator for the small area means. The results obtained improve previous findings, especially in the case of heteroskedastic data.     

Readiness for practice: social work students' perspectives in England,Italy, and Sweden

The aim of this article is to present the views of social work students from three different welfare regimes—Italy, Sweden, and England—and to analyze in what way at the end of their training they feel ready to practice. Primarily, it considers the findings of a comparative pilot study conducted in the three countries. Specifically, the paper initially offers general comments on the European context of standards of social work competence and how these impact on the countries involved here. It then briefly discusses the three different welfare regimes that these countries reflect. Social work education is then given some consideration, including reflection on similarities and differences in each curriculum. We then review examples of previous research on students' readiness to practice, also referencing models of competence previously developed. After this we look in detail at the research study itself, with a short discussion of its methodological—primarily phenomenological—approach and modest scope, before we consider tentative findings in relation to the themes of theory, practice, and personal growth. The paper concludes with reflections on levels of competence attained and how the research might best be extended.     

Life tables in actuarial models: from the deterministic setting to a Bayesian approach

The mortality dynamics experienced in the latest decades, especially at adult and old ages, has motivated the introduction of major innovations in the modeling of mortality for actuarial applications; such innovations concern, in particular, the representation of the uncertainty relating to aggregate mortality.     

Black‐White Biracial Children's Social Development from Kindergarten to Fifth Grade: Links with Racial Identification,Gender, and Socioeconomic Status

In this study, we investigated trajectories of Black‐White biracial children's social development during middle childhood, their associations with parents’ racial identification of children, and the moderating effects of child gender and family socioeconomic status (SES). The study utilized data from parent and teacher reports on 293 US Black‐White biracial children enrolled in the Early Childhood Longitudinal Study‐Kindergarten Cohort (ECLS‐K). Growth curve models suggested increasing trajectories of teacher‐reported internalizing and externalizing behaviors between kindergarten and fifth grade. Parents’ racial identification of children predicted child externalizing behavior trajectories such that teachers rated biracially identified children's externalizing behaviors lower relative to those of Black‐ and White‐identified children. Additionally, for White‐identified biracial children, the effect of family SES on internalizing behavior trajectories was especially pronounced. These findings suggest that in the USA, how parents racially identify their Black‐White biracial children early on has important implications for children's problem behaviors throughout the elementary school years.     

The Use of Risk Assessment to Decide the Control Strategy for Bluetongue in Italian Ruminant Populations

The affiliation, assessment and management of risks is a traditional part of veterinary medicine. In the past, veterinary services involved in this type of activity usually assessed risks qualitatively. However, since the 1990s, quantitative methods have become increasingly important. The establishment of the World Trade Organization in 1994, and the promulgation of its Agreement on the Application of Sanitary and Phytosanitary Measures (the "SPS Agreement") led to an increased application of import risk analysis and to significant improvements in the methodology of risk analysis as applied to international trade policy for animals and animal products. However, there was very little development of risk analysis in veterinary fields other than international trade and management of health risks to consumers of animal products and little has been published on its use in the choice and definition of control or prophylaxis strategies for animal diseases. This article describes a quantitative risk assessment, which was undertaken in Italy to help choose an appropriate national response strategy following an incursion of bluetongue, an infectious disease of sheep and goats. The results obtained in this study support the use of risk analysis as a tool to assist in choosing an appropriate animal disease management strategy. The use of risk analysis in the evaluation of disease management strategies also offers advantages in international trade. It makes easier the comparison of different strategies applied in the various countries, and thus facilitates the assessment of equivalence of the guarantees provided by different strategies.     

Why do they stay? A study of resilient child protection workers in three European countries

Whilst 50% of child protection workers across much of Europe and the affluent ‘West’ leave after two years, many stay and develop substantial professional careers. This paper discusses research in Italy, Sweden and England examining what factors explain ‘remaining’ for more than three years in this stressful job. Underpinned by a hermeneutic epistemology, qualitative interviews were undertaken and subject to an interpretative thematic analysis. The findings proved to be complex and multi-layered and this paper presents an overview of these. The theoretical framework for the project mainly drew on organisations and resilience, and the initial sections of the paper consider how formulations of resilience as contextual and relational can elucidate professional sustainability. Organisational issues are considered, including the impact of work management, of supervision and of allocation in different national contexts. The paper also focuses on the role of friendships and informal support at work. Threaded through these established themes are more, perhaps surprising, concepts: for example, creativity, power, reflexive spaces and interpersonal relations as explanatory of remaining in child protection work.     

EMPLOYEE FINANCIAL LITERACY AND RETIREMENT PLAN BEHAVIOR: A CASE STUDY

This article uses administrative data on all active employees of the Federal Reserve (FR) System to examine participation in and contributions to the Thrift Saving Plan, the System's defined contribution (DC) plan. We link to administrative records a unique employee survey of economic/demographic factors including a set of financial literacy questions. Not surprisingly, FR employees are substantially more financially literate than the population at large. Most importantly, financially savvy employees are also most likely to participate in their DC plan. Sophisticated workers contribute three percentage points more of their earnings to the DC plan than do the less knowledgeable, and they hold more equity in their pension accounts. We examine changes in employee plan behavior 1 year after employees completed a Learning Module about retirement planning, and we compare it to baseline patterns. We find that those employees who completed the Learning Module were more likely to start contributing and less likely to have stopped contributing to the DC plan postsurvey. In sum, employer‐provided learning programs are shown to significantly impact employee retirement saving decisions and consistent with a lot of other research, higher levels of financial literacy are found to have a beneficial impact on retirement saving patterns.
