The response to iron supplementation of pregnant women with the haemoglobin genotype AA or AS

The influence of haemoglobin genotype on the response to iron supplementation was studied in a randomized, double blind, placebo-controlled trial involving 497 multigravid pregnant women from a rural area of The Gambia. Women were randomly allocated to receive either oral iron (60mg elemental iron per day) or placebo. At 36 weeks of pregnancy, women who had received oral iron during pregnancy had higher mean haemoglobin, packed cell volume, plasma iron and ferritin levels than did women who received placebo. Iron supplementation of pregnant women with the AA haemoglobin genotype also resulted in increases in the packed cell volume (PCV) and haemoglobin level measured after delivery, and in the birth weight of the infant. However, in AS women PCV and haemoglobin level at delivery were lower in the supplemented group and supplementation was also associated with reduced birth weights. In malaria endemic areas, pregnant women with the haemoglobin genotype AS may not benefit from iron supplementation during pregnanc

Neoliberalism and University Education in Sub-Saharan Africa

This article reviews the history of university development in Sub-Saharan Africa (SSA) and discusses the impact of neoliberal policies. This will be followed by an examination of the problems facing universities in the region. The following questions will be explored: (a) Are the existing universities in SSA serving the development needs of the region? (b) Are these universities up to the task of moving SSA out of the predicaments it faces such as famine, HIV/AIDS, poverty, diseases, debt, and human rights abuses? Finally, the article argues that for universities to play a role in the development of the region, a new paradigm that makes university education a public good should be established

Historical Missionary Activity, Schooling, and the Reversal of Fortunes: Evidence from Nigeria

This paper shows that historical missionary activity has had a persistent effect on schooling outcomes, and contributed to a reversal of fortunes wherein historically richer ethnic groups are poorer today. Combining contemporary individual-level data with a newly constructed dataset on mission stations in Nigeria, we find that individuals whose ancestors were exposed to greater missionary activity have higher levels of schooling. This effect is robust to omitted heterogeneity, ethnicity fixed effects, and reverse causation. We find inter-generational factors and the persistence of early advantages in educational infrastructure to be key channels through which the effect has persisted. Consistent with theory, the effect of missions on current schooling is larger for population subgroups that have historically suffered disadvantages in access to education

Conceptualizing international education: From international student to international study

In a rapidly changing transnational eduscape, it is timely to consider how best to conceptualize international education. Here we argue for a conceptual relocation from international student to international study as a means to bridge the diverse literatures on international education. International study also enables recognition of the multiple contributions (and resistances) of international students as agents of knowledge formation; it facilitates consideration of the mobility of students in terms of circulations of knowledge; and it is a means to acknowledge the complex spatialities of international education, in which students and educators are emotionally and politically networked together through knowledge contributions

Narratives of nineteenth century drought in southern Africa in different historical source types

Single- to multiple-year drought episodes posed significant challenges for agrarian communities across southern Africa during the nineteenth century and hence are widely recorded in a variety of historical documents. However, the ways in which droughts are articulated, and the focus of individual accounts, vary considerably between different authors and historical source types. This study draws on a range of documentary source types—specifically newspapers, letters, reports and diaries—to explore the varied narratives associated with three protracted droughts (those of 1861–1863, 1876–1879 and 1895–1897) that affected large areas of the subcontinent. The analysis spans four case study areas—present day KwaZulu-Natal (South Africa), Lesotho, Malawi and the southern Kalahari (Botswana and South Africa)—which were investigated as part of different interdisciplinary projects. We explore issues common to all case study areas, including (i) how specific drought events are framed and (ii) what is and is not reported about individual droughts across different source types. We conclude that different source types in the subcontinent may be more or less appropriate for addressing the specific objectives of historical climatology, particularly in relation to historical drought. Sources such as newspapers and weather diaries are rich in qualitative and quantitative observations suitable for the reconstruction of temporal and spatial patterns of weather and climate, as well as climate-related natural disasters. In contrast, letters, reports and personal journals, especially those written by missionaries, provide additional qualitative narratives through which to investigate the vulnerability of past societies and economies to climate variations, and to explore past discourses and social representations of climate. While studies of this kind have been published for European and American source types, this is the first systematic exploration of documentary sources for the historical climatology of Africa. It should therefore provide a guide for climate history studies elsewhere in the continent, or other regions where written records are absent prior to the arrival of European colonists
