Deadly Cities? Spatial Inequalities in Mortality in sub‐Saharan Africa

We investigate whether sub‐Saharan African countries are affected by an “urban mortality penalty” repeating the history of industrialized countries during the nineteenth century. We analyze Demographic and Health Surveys from several sub‐Saharan African countries for differences in child and adult mortality between rural and urban areas. For the first decade of the 2000s, our findings indicate that child mortality is higher in rural than in urban areas for all countries. On average, child mortality rates are 13.6 percent in rural areas and 10.8 percent in urban areas. In contrast, average urban adult mortality rates (14.1 percent) have exceeded rural adult mortality rates (12.4 percent). Child mortality rates are on average 65 percent higher in urban slums than in formal settlements. Child mortality rates in slum areas are, however, still lower than or equal to those in rural areas for most countries in our sample.     

Slum Residence and Child Health in Developing Countries

Continued population growth and increasing urbanization have led to the formation of large informal urban settlements in many developing countries in recent decades. The high prevalence of poverty, overcrowding, and poor sanitation observed in these settlements—commonly referred to as “slums”—suggests that slum residence constitutes a major health risk for children. In this article, we use data from 191 Demographic and Health Surveys (DHS) across 73 developing countries to investigate this concern empirically. Our results indicate that children in slums have better health outcomes than children living in rural areas yet fare worse than children in better-off neighborhoods of the same urban settlements. A large fraction of the observed health differences appears to be explained by pronounced differences in maternal education, household wealth, and access to health services across residential areas. After we control for these characteristics, children growing up in the slums and better-off neighborhoods of towns show levels of morbidity and mortality that are not statistically different from those of children living in rural areas. Compared with rural children, children living in cities (irrespective of slum or formal residence) fare better with respect to mortality and stunting but not with respect to recent illness episodes.     

Placement stability in non-kinship foster care: variables associated with placement disruption

In Spain research has been conducted into the outcomes of foster care, although there is a need for further analysis, especially as regards the variables associated with placement disruption. In 2008 (T1) was collated information on all foster placements that were registered in three Spanish provinces. In 2014 (T2), data were gathered by reviewing the children's case notes and through interviews with the social worker responsible for each case. The resulting sample comprised 104 non-kinship foster children in long-term foster care who were being fostered in 86 families. The results obtained at T2 showed that the percentage of children who were still living with the same family (68.3%) was greater than the proportion of children whose circumstances had changed (31.7%). The social workers considered that placement disruption had occurred in 27 of the 33 cases. One of the main finding was placement disruption was associated with the older age at the time of being fostered and the emotional relationship quality between children and foster carers. A regression analysis showed that low levels of warmth and communication in the relationship between child and foster carers were shown to be a predictor of placement breakdown. Implications for practice are discussed.     

Professional competencies in social work education for the third sector in southern Spain

The education of social workers in the Spanish university is structured around the professional competencies that will subsequently be applied in the labour market. As social work is a profession focused on the provision of social welfare and the prevention of social exclusion, it is expected of social workers that they become analytical, thoughtful professionals within their environment and that they play an active role in preventing social exclusion and inequality. However, there are important splits and contradictions between the official recognition of such competencies by universities and their effective implementation in the labour market. In this paper we analyse the main constraints and contradictions involved in the acquisition of the professional skills of social workers in their transition to the labour market. To do this, we focus on the specific case competencies in professional field of the third sector in Andalusia     

Maternal and Paternal Mental‐state Talk and Executive Function in Preschool Children

The present study examined the relationship between parents’ mental‐state talk and preschoolers’ executive function. Seventy‐two children participated in the present study, as well as their mothers and fathers. When children were enrolled in the second preschool year, mothers’ and fathers’ use of mental‐state references were assessed during a shared picture‐book reading task with the child. Later, four months before admission to the first grade, preschoolers’ executive function was measured. Hierarchical regression analysis revealed that maternal, but not paternal, mental‐state talk was a significant predictor of children's executive function composite, even after accounting for child gender, age, verbal ability, and parental education. When looking at each of the EF components, maternal mental‐state talk proved to be a predictor of set‐shifting whereas no significant relations emerged with inhibitory control or working memory. These findings add to prior research on parenting quality and executive function in preschoolers.     

Popular Literature in Africa: Post-Resistance Perspectives

This paper argues that our primary concern in responding to wrongdoing should be distinct from our concern with the just distribution of wealth: retributive justice serves an important moral end that is independent of the promotion of welfare. I proceed by comparing retributive justice to restorative justice, because the latter offers a paradigm often aimed at replacing retributive justice, and is more closely concerned with social justice. I suggest that there are different possible paradigms of restorative justice, that one which is closer to social justice is less plausible and that a more plausible model need not be in tension with retributive justice, but could rather fall under it. I do not, however, conclude that there is no relation between retributive and social justice; while they relate to importantly distinct moral claims, I provide reasons for thinking that the moral justification of our system of punishment depends on the existence of at least some measure of social justice. The aim of retributive justice is importantly distinct from the just distribution of wealth, but this distinct aim cannot be served without some degree of justice in the distribution of wealth.     

PORT Hill and Moment Estimators for Heavy-Tailed Models

In this article, we use the peaks over random threshold (PORT)-methodology, and consider Hill and moment PORT-classes of extreme value index estimators. These classes of estimators are invariant not only to changes in scale, like the classical Hill and moment estimators, but also to changes in location. They are based on the sample of excesses over a random threshold, the order statistic X _[np]+1:n , 0 ≤ p < 1, being p a tuning parameter, which makes them highly flexible. Under convenient restrictions on the underlying model, these classes of estimators are consistent and asymptotically normal for adequate values of k, the number of top order statistics used in the semi-parametric estimation of the extreme value index γ. In practice, there may however appear a stability around a value distant from the target γ when the minimum is chosen for the random threshold, and attention is drawn for the danger of transforming the original data through the subtraction of the minimum. A new bias-corrected moment estimator is also introduced. The exact performance of the new extreme value index PORT-estimators is compared, through a large-scale Monte-Carlo simulation study, with the original Hill and moment estimators, the bias-corrected moment estimator, and one of the minimum-variance reduced-bias (MVRB) extreme value index estimators recently introduced in the literature. As an empirical example we estimate the tail index associated to a set of real data from the field of finance.     

Blind nonparametric regression

One must sometimes follow the evolution of several individuals which cannot be distinguished. The author proposes a graphical estimator of individual evolution that can be used in such cases. She shows that this estimator is consistent and asymptotically normal.
