This book describes the choices open to farming families in the Sahelian village of Kala, in central Mali. Life in this drought-prone region is harsh and full of risk to health, crops, and livestock, yet there are also opportunities open to the hard-working, audacious and lucky, bringing considerable returns if the timing is right. Three inter-related themes underlie the analysis of production and investment decisions faced by households; the role of risk, the long timeframe within which decisions are made, and the close links between economic performance and household size and organisation. Climatic variability and demographic uncertainty lie at the heart of domestic structures; the extreme vulnerability faced by single individuals means people cluster in large kin-based groups, pooling risks and providing protection. The very limited development of labour markets means that households rely almost entirely on their own members for their workforce, and generating the capital needed for investing in ploughs, wells, carts and livestock must stem from a good year’s grain surplus and migration earnings. Based on field-research over the period 1980-82, this study illustrates a successful response to making ends meet in a land abundant region, despite high risks of drought. A follow-up study of this village was published in 2020: Land, Investment, and Migration. Thirty-five years of village life in Mali (OUP).

Abstract Background: Previous studies have suggested negative parenting environments, especially harsh parenting, is a specific risk factor for non-suicidal self-injury (NSSI). However, the potential mechanism between harsh parenting and NSSI has not been explored. Based on the experiential avoidance model and empirical researches, we aimed to examine if depressive symptoms are a mediator between harsh parenting and NSSI. Moreover, the catechol-O-methyltransferase (COMT) Val158Met polymorphism related to depressive symptoms may also exert a moderating effect on NSSI, thus, the interaction between harsh parenting and COMT were also considered in our study.Method:373 junior high school students were recruited for the study by using a longitudinal design. Adolescents answered self-report questionnaires and provided Saliva samples for DNA genotyping.Result:The results revealed that harsh parenting was positively associated with NSSI after 18 months, and this association was mediated by depressive symptoms. Moreover, the moderating role of COMT in the direct and indirect effect of harsh parenting on NSSI only among adolescents with two Val alleles. However, the relationship was not significant for Met carriers.Conclusion: Genetic variations of COMT Val158Met may be a critical candidate in understanding the development of depression and NSSI. We conclude that the Val homozygotes of the COMT Val158Met polymorphism play a susceptible role both in depressive symptoms and NSSI.

Abstract Objectives The aim of this study was to investigate the effect of self-reported workplace bullying on depressive symptoms in a prospective study among a representative sample of employees from Germany. We focused specifically on the role of the perpetrator (co-workers and superiors), which was never done before in a longitudinal design. Methods We used data from a nation-wide representative panel study with a 5-year follow-up (N = 2172). Data on bullying exposure were obtained separately for different perpetrators (co-workers and superiors) and degree of severity (severe bullying, i.e., at least weekly). Depressive symptoms were assessed with the Patient Health Questionnaire (PHQ). We used logistic regression analyses to examine the effect of workplace bullying at baseline on depressive symptoms at follow-up. Results After adjusting for baseline depressive symptoms, severe bullying by co-workers significantly increased the 5-year risk of depressive symptoms (OR = 2.50). Severe bullying by superiors had a nonsignificant effect. Conclusions Workplace bullying is a risk factor for depressive symptoms among employees in Germany. The type of perpetrator seems to be an important factor to consider, as indicated by the elevated risk of depressive symptoms when bullying is perpetrated by co-workers.
