Death and schooling decisions over the short and long run in rural Madagascar

This paper provides strong evidence that adult mortality has a negative impact on children educational outcomes, both over the short and the long run, in rural Madagascar. The underlying longitudinal data and the difference-in-differences strategy used overcome most of the previous cross-sectional study limitations, such as failure to control for child and household pre-death characteristics and unobserved heterogeneity. This paper also pays special attention to the heterogeneity, robustness, and long-run persistence of effects. Results show that orphans are on average 10 pp less likely to attend school than their nonorphaned counterparts, this effect being even more pronounced for girls and young children from poorer households. Results on adults further show that those orphaned during childhood eventually completed less education. These findings suggest that not only do households suffering unexpected shocks resort to schooling adjustments as an immediate risk-coping strategy, but also that adversity has long-lasting effects on human capital accumulation.     

Composition and decomposition in nonmarital fertility

Ermisch (2009) criticized Gray, Stockard, and Stone (2006), arguing that they incorrectly tested a model positing a nonlinear relationship between the nonmarital fertility ratio and the proportion of unmarried women. I identify a different problem, which is that even if this model were to hold for a particular population, it would not in general hold for subgroups of this population; likewise, were it to hold for subgroups, it would not hold for aggregations of these subgroups.     

Maternal union instability and childhood mortality risk in the Global South, 2010–14

Efforts to improve child survival in lower-income countries typically focus on fundamental factors such as economic resources and infrastructure provision, even though research from post-industrial countries confirms that family instability has important health consequences. We tested the association between maternal union instability and children’s mortality risk in Africa, Latin America and the Caribbean, and Asia using children’s actual experience of mortality (discrete-time probit hazard models) as well as their experience of untreated morbidity (probit regression). Children of divorced/separated mothers experience compromised survival chances, but children of mothers who have never been in a union generally do not. Among children of partnered women, those whose mothers have experienced prior union transitions have a higher mortality risk. Targeting children of mothers who have experienced union instability—regardless of current union status—may augment ongoing efforts to reduce childhood mortality, especially in Africa and Latin America where union transitions are common.     

Reconstruction of populations by stochastic optimization: Sensitivity analysis

The reconstruction of populations by stochastic optimization solves the nontrivial problem of finding demographic flows from population registers or vital statistics and censuses, if available. These flows allow the reconstruction of stocks (age pyramids and vital statistics). After a review of reconstruction methods, the sensitivity analysis shows the robustness of the method by stochastic optimization to flawed or missing values, to the length of the reconstruction period, and to variations in the actual demographic flows.     

Causal Ordering of Basic Psychological Needs and Well-Being

What is the relationship between well-being and satisfaction of basic psychological needs overtime? The basic psychological needs theory is a subtheory of the self-determination theory that elaborates the concept of psychological needs and its relations to psychological health and well-being. The goals of this research was to establish the causal ordering between basic psychological needs and three psychological well-being indicators (subjective well-being, self-esteem and satisfaction with life), in a longitudinal study. We used a cross-lagged two-wave design. A total of 272 university students completed the questionnaire at the beginning and at the end of the semester. Relatedness at time 1 (T₁) had a positive and significant effect on all well-being indicators at time 2 (T₂); competence (T₁) had a positive and significant effect on all indicators except for self-esteem (T₂); finally, autonomy (T₁) did not have a significant effect on any of the well-being indicators (T₂). In conclusion, we confirm the causal ordering of competence and relatedness on well-being, according to the basic psychological needs subtheory. Universities, in general, and teachers, in particular, should promote relations between students and support the need of competence.     

An update on ‘a comparative study of tests for homogeneity of variance’

Tests for equality of variances using independent samples are widely used in data analysis. Conover et al. [A comparative study of tests for homogeneity of variance, with applications to the outer continental shelf bidding data. Technometrics. 1981;23:351–361], won the Youden Prize by comparing 56 variations of popular tests for variance on the basis of robustness and power in 60 different scenarios. None of the tests they compared were robust and powerful for the skewed distributions they considered. This study looks at 12 variations they did not consider, and shows that 10 are robust for the skewed distributions they considered plus the lognormal distribution, which they did not study. Three of these 12 have clearly superior power for skewed distributions, and are competitive in terms of robustness and power for all of the distributions considered. They are recommended for general use based on robustness, power, and ease of application.     

Language in the process of labour market rationalisation: A sociohistorical approach across twentieth-century Spain

This article analyses the role of linguistic skills in the process of defining professional classifications in Spain during 1919–1980. The aim is to determine the social evaluation of the skills involved. To retrace the classifications, a total of 114 official documents were examined, establishing a chronological division into three major stages: 1920–1940, 1940–1960 and 1960–1980. The first period (1920–1940) shows efforts toward the initial objectification of working conditions and salary scales, revealing social prejudices and tacit conventions shaping the employment hierarchy, while the second one (1940–1960) indicates the extent to which office work stood out over manual work. Finally, the third stage (1960–1980) shows processes of language rationalisation, which entailed attempts to standardise positions based on required skill sets.     

A transnational practice between fractured homes: Second-generation Turkish–German migrants’ experiences of visiting and being visited

The paper explores the multiple ways in which visits affect the understanding of home for the Turkish–German second generation who have relocated to Turkey. Based on thematic–narrative analysis of 116 life-story interviews with second-generation ‘returnees’ in five regions of Turkey, three types of visits are identified: (i) family visits to Turkey whilst growing up in Germany; (ii) visits to Germany after the second generation has ‘returned’ to Turkey; (iii) visits to Turkey by the second generation's Germany-residing relatives and friends. Each type has different meanings for the visitors and the visited, creating fluid reflections on the meaning of home, which, especially for the second-generation ‘returnees’, tends to become fractured. Constantly comparing their two home(-land)s since childhood, they often simultaneously feel both ‘here’ and ‘there’ as a result of changing attachments and a mix of positive and negative experiences in both locales with their families, friends and the dominant others.
