Spatial/spatiotemporal interdependence—that is, that outcomes, actions or choices of some unit-times depend on those of other unit-times—is substantively important and empirically ubiquitous in binary outcomes of interest across the social sciences. Estimating and interpreting binary-outcome models that incorporate such spatial/spatiotemporal dynamics directly is difficult and rarely attempted, however. This article explains the inferential challenges posed by spatiotemporal interdependence in binary-outcome models and recent advances in their estimation. Monte Carlo simulations compare the performance of one of these consistent and asymptotically efficient methods (maximum simulated likelihood, using recursive importance sampling) to estimation strategies naïve about (inter-) dependence. Finally, it shows how to calculate, in terms of probabilities of outcomes, the estimated spatial/spatiotemporal effects of (and response paths to) hypotheticals of substantive interest. It illustrates with an application to civil war in Sub-Saharan Africa.

Analytical Tools

Famine, a complex phenomenon with multifactorial causes, produces starvation and associated diseases resulting in unusually high mortality from a lack of food. Devastating famines in sub-Saharan Africa in the 1980s may have provided an impetus for scholars to find additional analytical tools for predicting famines. Two predominant theories of famines causality are (1) food availability decline (FAD), a supply failure; and (2) the entitlement approach based on a demand failure. Findings from both theories are applied to specific examples from Ethiopian famines to analyze the composition and effects of famine. The limited success of contemporary famines studies in anticipating famine suggests the need for improved analytical tools. Risk factor analysis, used successfully in the social sciences and the medical sciences to predict the occurrence of complicated phenomena, is developed to identify controllable, uncontrollable, and contributing factors to famine. Based on the experience of Ethiopia in 1983-86, categorical cutoff values for identifying a high risk of developing famine are formulated.

Published European first-hand accounts of the coastlands from Senegal to Angola for the period c. 1445-c. 1700 are examined to see what light they throw on the extent to which institutions of servitude in pre-colonial sub-Saharan Africa were autonomous developments or a response to external demands for African slaves. It seems clear that when, in the early years of this period, European traders first approached societies along the western African coasts, they were commonly offered what they called ‘slaves’ in exchange for the goods they had brought. But it would be wrong to conclude from this that a slave class was necessarily a feature of western African coastal societies when these were first contacted by Europeans. It is clear, for instance, that the Europeans preferred to deal with societies which had developed monarchical governments, whose leaders had control of sufficient surpluses to make trade worthwhile. The evidence suggests that in these societies most individuals were dependants of a ruling and entrepreneurial elite, but that there was also social mobility. A category of dependants that particularly attracted the notice of the European observers was women, whom men of power and wealth tended to accumulate as wives (and hence as the potential mothers of still more dependants). The necessarily limited supply of women may have been a factor encouraging such men to seek to increase their followings, and thus their status, power and wealth, by recruiting other dependants by forcible, judicial and economic means. While many such dependants, or their offspring, would be assimilated into the social groups commanded by their masters, the latter were certainly willing to contemplate using recently acquired or refractory recruits in other ways, such as exchanging them for alternative forms of wealth.

Architectural Modernism

With the aim of contributing to the documentation and conservation of the modern architectural heritage, this paper presents Monteiro & Giro Complex (M&G), built during the 50’s in Quelimane, Mozambique, with the goal of stressing the modernity of the social program and the technological approach. If one wants to gain a better understanding of the worldwide Diaspora of architectural modernism, it is essential to document and analyse the important heritage of sub–Saharan Africa. Modern architectural debates have been reproduced, transformed, contested and sometimes even improved in distant lands and overseas territories. These contradictory aspects of Modernist practice are revealed in the programmatic, technological and structural M&G industrial Complex.

Sub-Saharan Africa (SSA) has become the top priority for international funders and they are now increasing their cross-border funding to microfinance institutions (MFIs) in the region. This foreign funding is considered an additional source of capital for MFIs in the region who are facing difficulties in meeting the demand of the poor. However, these funds are provided by public and private funders who each have different motives. The paper examines the impact of these different sources of funding on microfinance performance and mission drift in SSA, which is the world’s poorest region. The study utilizes data from 212 MFIs in 30 SSA countries accessed over a three-year period (i.e. 2007, 2009, and 2011). The findings show that cross-border funding does not affect either the social or financial performance of MFIs when time and country effects are accounted for.

Some of the most controversial aspects of China’s economic presence in Sub-Saharan Africa (SSA) relate to the social, political, and environmental impacts. Many of the claims that are made are based on anecdotal evidence, and there is a need for more systematic research on these aspects. In terms of social impacts, the chapter discusses employment, wages, working conditions, and labour rights. Political issues addressed include claims that China’s involvement supports authoritarian regimes, encourages corruption, and leads to conflict and political instability. These claims are not generally supported, and SSA countries have benefitted from the increased policy space that Chinese involvement gives them. The environmental effects of both increased exports to China and the activities of Chinese firms in SSA are analyzed. Contrasting case studies illustrate the negative impacts of China on forestry, and the positive effects of Chinese support for wind and solar power.

New Research

Over the past two decades, a sociology of global health has emerged. While this new subfield takes up some themes and issues that are familiar to the discipline as a whole—among them organizations, social movements, and the social construction of illness—it has also posed new questions and opened new research pathways by formulating and testing theory in environments radically different from the United States. This work has forced sociologists to confront the ethnocentrism of research paradigms that are grounded in the American experience and to consider classical assumptions and constructs in fruitful new ways. Notable recent literature reviews have taken up the issue of HIV/AIDS in sub-Saharan Africa, comparative healthcare systems, and the sociology of development. However, this review is the first to outline the contours of a coherent sociology of global health. It addresses several questions: What issues are being taken up in this emergent subfield? What added value comes from turning scholarly attention beyond our borders? And what new research agendas lie on the horizon?
