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.     

Characterizing parameters of multivariate elliptical distributions*

This paper defines new parameters characterizing multivariate elliptical distributions. Mardia's coefficient of multivariate kurtosis is shown to be essentially one of these parameters. A simple relation is established between centered multivariate product moments and second moments of the variables. The general results are verified on the contaminated normal distribution as an example.     

The impacts of rapid demographic transition on family structure and income inequality in Brazil, 1981–2011

This study analysed the impact of changing family structure on income distribution. Specifically, it analysed how changes in the proportions of different categories of family in the population contributed to increases in the income of the richest and poorest social strata in Brazil, and the consequent impacts on income inequality. Rural and urban families were compared in order to understand how these dynamics had different impacts on more developed (urban) and less developed (rural) areas. The results emphasize how changes observed in family structure are more pronounced among the richest families, contributing to an increase in (i) the income of the richest families and (ii) income inequality between the richest and poorest families, as well as between urban and rural areas.     

After the MDGs: From Social Development to Technoenterprise in Tanzania

Abstract

This article explores how a development paradigm changes in Tanzania as the social sector concerns of the Millennium Development Goal era are practically and politically superseded by a commitment to private sector-driven structural transformation. Changes in the content and orientation of development do not occur as a result of evaluating what kinds of interventions are effective. They are the outcome of concerted efforts of paradigm reconstruction in which the role of development knowledge is pivotal. The process of policy shift entails a reorganisation of the architectures established to support the previous aid regime, including altering the roles of development knowledge producers and civil society organisations. New political relations between business interests and development actors support the increased influence of philanthropic foundations in determining the development agenda, which is sustained by new configurations of development knowledge. These shifts have important political implications for the kinds of policies considered developmental and the extent to which development orthodoxies can be contested.     

Analysis of the compensatory postures adopted by day caregivers through OWAS-Ovako Working Posture Analysing System

The Ergonomic Work Analysis reports that there are many activities performed by the professional caregivers and that they are exposed to physical and psychological overload. This situation favors the emergence of pain which influences the quality of life in the work place. In this way, the objective of this study was to verify the main postural constraints adopted by caregivers in public day cares. Visits were conducted in 28 day cares aiming at performing an interview to 126 caregivers who have been working for more than 4 years. From the questionnaire it was found that 80% of the participants refer some sort of pain, being 42% in the trunk, 33% in the shoulder and 25% in the lower limbs. The data from OWAS method showed that from the total of 30 postures performed during the work One could see that the main postures adopted by the caregivers were: flexion, lateral inclination and rotation of the trunk and most of the time they are standing. These movements, when bad performed, can lead to injuries in the lower limbs, upper limbs and trunk. It's necessary more attention to these workers.Thought preventive ergonomic actions to reduce pain symptoms and promote a work in health and safety.     

Psychopathology,physical complaints and health risk behaviors among youths who were victims of childhood maltreatment: A comparison between home and institutional interventions

Based on investigations of child maltreatment by Child Protective Services (CPS), several children who are identified receive some kind of individual or familial intervention. However, the literature has shown conflicting results in regard to the later functioning of the children who are target of different protective measures in different settings, compared to other youths who receive no intervention. We assessed childhood adversity, psychopathology, physical complaints and health risk behaviors among youths who received one of two different protective interventions during childhood (home vs. institutionalization group), and we compared them with youths who receive no intervention (comparison group). In total, 216 youths participated, with ages ranging from 14 to 23 years (M = 17.05 years, SD = 1.8 years; 105 males, 111 females), including 136 youths that were contacted based on their CPS records completed during their childhood, and 80 youths from the community without CPS identification.     

Rereading Canonical Identity: A Sexual Ethics of Bible Interpretation

This article is a response to Lisa Baraitser's Maternal Encounters: The Ethics of Interruption (2009 Baraitser , L. ( 2009 ). Maternal Encounters: The Ethics of Interruption . Hove , UK, and New York, NY : Routledge . [Google Scholar]). It focuses on the concept of encounter as part of an emerging subjectivity or a subjectivity in production. By putting Baraitser's maternal encounters alongside art encounters the discussion starts to open up thinking on the different potential ways for humans to be interrupted and the implications of such potential subjective and ethical awakenings in this late capitalist contemporary era.
