Gender nonconformity, homophobia, and mental distress in latino gay and bisexual men

This study explored whether gender nonconformity in gay and bisexual men is related to mental distress and if so, whether this relationship is mediated by negative experiences that are likely associated with gender nonconformity, including abuse and harassment. To study this question, data were analyzed from face-to face interviews with 912 self-identified gay and bisexual Latino men in three major U.S. cities collected by Diaz and colleagues (2001). Gay and bisexual Latino men who considered themselves to be effeminate had higher levels of mental distress and more frequently reported various negative experiences, compared with gay and bisexual Latino men who did not identify as effeminate. Higher levels of mental distress in effeminate men seemed to primarily result from more experiences of homophobia. Findings suggest the need for more attention to gender in research as well as counseling of sexual minority men.     

Etiological Patterns of Child Abuse and Neglect

A review of the various etiological possibilities for child abuse and neglect, designed to offer an additional and different possibility. Consideration is first given to problems, namely the lack of universal definition, heterogeneous effects, and retrospective research. The probability of multifactor models is noted, and sexual abuse is given separate consideration, followed by an exploration of the existing models termed ecological, transactional, transitional, and attachment. An interactive aggression model is then offered as the new possibility. Empirical evidence for cultural and/or ethnic predispositions suggests that society can be a supporting or inhibiting factor in terms of promoting or opposing violence.     

A Psychosocial View of Mental Illness: An Introduction to Part II

Increasingly, grandmothers are parenting grandchildren in homes where parental presence is sporadic or nonexistent. A disproportionate percentage of African American grandparents fall in this category. The author reviews the literature on the African American grandmother in the context of the African American family and describes a practice model for service provision to those women who seek support as they “parent again.”     

Alcohol Consumption Among University Students in North Rhine–Westphalia,Germany—Results From a Multicenter Cross-sectional Study

Abstract

Objective: To assess alcohol use and problem drinking among university students in the German Federal State of North Rhine–Westphalia (NRW) and to examine the associated factors. Method: A multicenter cross-sectional study was conducted in 16 universities in 2006–2007 in NRW by a standardized questionnaire and 3,306 students provided information (response rate of 88%). Problem drinking was measured by the CAGE questionnaire. Results: Alcohol consumption in the last 3 months was reported by >90 % of students. About 80% reported heavy drinking, and 20% displayed problem drinking. Male students, students living in residence halls, and students from sport faculties had a higher risk of heavy drinking and problem drinking. When students were compared across study years, frequency of heavy drinking decreased with higher semesters. Conclusions: Overall, heavy drinking and problem drinking are common among university students in this sample. Intervention programs should be designed for students at a particularly high risk.     

Food Access and Shocks in Rural Households: Evidence from Bangladesh and Ethiopia

As remarked by Ravallion (J Dev Econ 99:201–209, 2012), the recent switch from arithmetic to geometric mean in the aggregation of the United Nations’ Human Development Index has caused a more severe inequality penalization of the index for less developed countries, with outlying consequences. We clarify and explain this fact and propose an aggregation function, the Trichotomy Mean, that depends on two parameters: one regulates the overall penalization of disequilibria (among or within dimensions) in analogy with Atkinson’s inequality aversion parameter for power means; the other modulates the Level Dependence of the Adjustment, a novel concept describing the behavior—decreasing, increasing, or constant—of penalization of given disequilibria for increasing index level. Unlike the geometric mean (which, incidentally, has decreasing LDA type), the TM remains valid for zero or negative—and does not distort for small positive—values of the input variables, thus permitting less restrictive raw-variable normalizations and to overcome the need for exogenous lower bounds. We compare the three versions of TM with the geometric mean in an empirical analysis on the HDI 2014 data. We finally illustrate the contributions of the TM to the development literature debate.     

An Evaluation of the NERJIT Priority Rule in a Kanban‐Controlled Flowshop

Significant progress in production and information technologies and innovations in management of operations during the last couple of decades have made the production of small lots and deployment of Just‐In‐Time (JIT) concepts in flowshops possible. As a result, some researchers and practitioners have been seeking to improve the performance of non‐repetitive systems using JIT concepts. In this process, the JIT concepts that were originally designed for mass production have been modified to adapt JIT to non‐repetitive systems. This article uses a priority rule that is based on real‐time demand and production information for sequencing jobs in a kanban‐controlled flowshop. The analysis of the effect of this priority rule; the number of kanbans; the length of the withdrawal cycle; First‐Come, First‐Served (FCFS); and Shortest Processing Time (SPT) on four performance measures—customer wait time, total inventory, input stock‐point inventory, and output stock‐point inventory, shows that the use of this priority rule results in a significant reduction of customer wait time and a slight decrease in inventory.     

Multivariate survival mixed models for genetic analysis of longevity traits

A class of multivariate mixed survival models for continuous and discrete time with a complex covariance structure is introduced in a context of quantitative genetic applications. The methods introduced can be used in many applications in quantitative genetics although the discussion presented concentrates on longevity studies. The framework presented allows to combine models based on continuous time with models based on discrete time in a joint analysis. The continuous time models are approximations of the frailty model in which the baseline hazard function will be assumed to be piece-wise constant. The discrete time models used are multivariate variants of the discrete relative risk models. These models allow for regular parametric likelihood-based inference by exploring a coincidence of their likelihood functions and the likelihood functions of suitably defined multivariate generalized linear mixed models. The models include a dispersion parameter, which is essential for obtaining a decomposition of the variance of the trait of interest as a sum of parcels representing the additive genetic effects, environmental effects and unspecified sources of variability; as required in quantitative genetic applications. The methods presented are implemented in such a way that large and complex quantitative genetic data can be analyzed. Some key model control techniques are discussed in a supplementary online material.     

Working life and retirement pensions in Spain: The simulated impact of a parametric reform

This article aims to offer an ex ante evaluation of the impact of a parametric reform of the Spanish pension system that would involve increasing the reference period used to calculate benefits, an approach proposed many times by various actors in the socio‐economic field. Such gradual change may be categorized as a non‐structural reform of the pension system. This contrasts with reforms of a structural nature that have been very popular in Latin America and elsewhere, involving the creation of defined contribution individual account schemes. As regards the parametric reform proposed in this article, the main findings indicate that it would have a small but negative impact on pension income for pensioners and would reduce income distribution.
