TIC et gains de productivité en Afrique subsaharienne

Les auteurs examinent les effets des TIC sur la productivité à partir d'un échantillon de 43 pays d'Afrique subsaharienne. Ils concluent que le développement des téléphonies fixe et mobile stimule la croissance de la productivité dans un processus à rendements croissants, confirmant l'existence d'un effet de réseau. Ainsi, la multiplication par deux du taux de pénétration des téléphonies fixe et mobile augmente les gains de productivité de 0,12 à 0,15 et 0,05 pour cent environ, respectivement. En outre, dans la région, l'accès facilité aux services bancaires et financiers serait l'un des vecteurs de l'effet de la téléphonie mobile sur la productivité.     

Girls Get Free Drinks: Undergraduates’ Misunderstandings of Heterosexual Privilege

Heterosexual privilege is a challenging concept to teach in undergraduate courses. Using data from self-reflection essays on the first and last days of the semester, we present students’ learning and growth in their understanding of heterosexual privilege and their ability to distinguish it from cisgender privilege. The majority of students accurately identified an instance of heterosexual privilege in their lives and discussed the counterpart to privilege: the marginalization and/or disenfranchisement experienced by individuals who hold other sexual identities. This article highlights the two most common misunderstandings of heterosexual privilege that emerged in students’ writing. On the first day of class, 18.2% outright denied that heterosexual privilege exists, and 17.6% conflated gender with sexuality. It reduced to 11.9% and 11.3%, respectively, on the last day of class. We saw growth in students’ sophistication of perspective even for some students who demonstrated these misunderstandings at the end of the term.     

Urban predator–prey association: coyote and deer distributions in the Chicago metropolitan area

We examined how predator or prey presence, as well as local and landscape factors, influence the distribution of coyotes (Canis latrans) and white-tailed deer (Odocoileus virginianus) in the Chicago metropolitan area. We collected data for 2 years at 93 study sites along 3 transects of urbanization using motion-triggered cameras. Our primary objective was to determine the relationship among coyote and deer spatial and temporal distribution, habitat characteristics, and human activity using multi-season patch occupancy models. Coyote occupancy was most strongly linked to rates of site visitation by humans and dogs, and was more likely farther from the urban center, with coyote colonization of sites inversely related to road density, housing density, and human and dog site visitation. Deer more frequently occupied sites with high canopy cover near water sources and colonized smaller sites with reduced housing density and human and dog presence. Expected predator–prey dynamics were altered in this highly urban system. Though we predicted deer would avoid coyotes on the landscape based on an “ecology of fear” framework, deer and coyote occupancy showed a strong positive association. We suggest that a scarcity of quality habitat in urban areas may cause the species to co-occupy habitat despite potential fawn predation. Modifying human foot traffic in green spaces may represent a useful tool for management and conservation of large urban mammals.     

Work, employment and mental health in Europe

In May 2004 the World Health Organization (WHO European Region) called a consultation meeting of its Collaborating Centres in Occupational Health to discuss mental health in the workplace. The meeting took place in Copenhagen. This paper presents an interpretation of the discussion that took place and the thinking that developed as a result. It was argued that increased interest and research and improved practice in the area of occupational mental health are required to promote good mental health in the European population. A framework of risk management and prevention based on sound evidence and good understanding could provide the basis for the translation of existing research knowledge into effective practice.     

Expanding economic protection to the elderly in Latin America

This article addresses the reforms introduced in Latin American pension systems that had the aim of increasing coverage beyond formal‐sector workers. For this purpose, fourteen representative regional experiences are analysed using a taxonomy based on features of the cases examined in terms of design, implementation and results. The findings show that, although the reforms share the goal of expanding coverage, there are significant differences deriving from the context in which they were originally designed, their goals, and the capacity available to implement them. The results are not homogeneous, and it is possible to identify some aspects in which policy decisions can lead to better or worse results.     

The Effect of Women’s Empowerment in Agriculture on Household Nutrition and Food Poverty in Northern Ghana

The study examines the effect of women’s empowerment in agriculture on household nutrition—i.e. the availability of carbohydrates, protein, and fat—and household food poverty measured by monetary food shortfall. The analysis is done by applying instrumental variable estimation to a sample of 2642 households from a 2012 population-based survey conducted in northern Ghana. Overall, the results indicate that women’s empowerment positively influences nutrient availability and negatively influences monetary food shortfall. By decomposing women’s empowerment into its component domains, this study identified that the domains of Income, Production, and Leadership are areas for intervention to influence households’ nutrient availability and monetary food shortfall outcomes. The effect of the Time and Resources domains reveal that some intra-household trade-offs may exist. Thus, policies aimed at empowering women to ultimately improve household nutrition and food poverty need to be based on the understanding of these specific interactions.
