Thinking about security in Africa

This article attempts to clarify some of the central questions and distinctions that provide the necessary backdrop for thinking in a sophisticated way about security in Africa. Drawing on the developing Critical Security Studies literature it suggests that an understanding of security based on people, justice and change offers the surest route to a stable future. It then sketches preliminary answers to some fundamental questions, namely: whose security should be prioritized? How have security dynamics in Africa been influenced by the wider processes driving world politics? What clusters of threats are the most salient? Where do such threats have the most pernicious effects? Which actors are best placed to alleviate those threats? And what sort of institutions should be built to assist in that process? The role of outsiders concerned with promoting security on the continent should be to try to ensure that as many Africans as possible are able to voice their opinions on these crucial issues.     

The future of US–Brazil relations: confrontation,cooperation or detachment?

US–Brazilian relations sunk to one of their lowest points ever following last year's exposure of the US government's massive surveillance of the South American giant—including the correspondence of President Rousseff and the business operations of Brazil's national oil company, Petrobras. Brazilian authorities responded angrily. The Brazilian president called off a highly valued state visit to Washington, denounced the US for violations of sovereignty and human rights, and proceeded to bypass the US to purchase nearly $5 billion worth of fighter aircraft from Sweden. In fact, US–Brazil ties have not been constructive for more than a generation. Yes, relations are mostly amiable, but with limited cooperation, considerable discord and some open clashes. Washington views Brazil primarily as a regional actor, and wants its cooperation mainly on inter‐American issues. For Brazil, regional collaboration means working with other Latin American nations—not the United States. Brazil usually wants the US to keep a distance from the region. The US is no more enthusiastic about Brazil assuming a global role; differences over some of the world's most dangerous political and security challenges have made Washington uneasy about Brazil's engagement in international affairs and critical of its foreign policy judgements. Relations will probably improve, but they could get worse. The two governments need to acknowledge that their relationship is fragile and troubled, and take steps both to rebuild trust and to avert further deterioration and new confrontations. They have to be more careful with each other.     

After Westgate: opportunities and challenges in the war against Al‐Shabaab

The attack on the Westgate Mall in Nairobi, Kenya, in September 2013 intensified international scrutiny of the war against Harakat Al‐Shabaab Mujahideen (Movement of the Warrior Youth). This article analyses the current state of affairs with reference to the three principal sets of actors in this war: Al‐Shabaab, the African Union Mission in Somalia (AMISOM) and its international partners, and the various actors currently involved in building the Somali Federal Government's security forces. It argues that although the newly reconfigured Al‐Shabaab poses a major tactical threat in Somalia and across the wider Horn of Africa, the movement is becoming a less important actor in Somalia's national politics. As Al‐Shabaab loses territory and its popularity among Somalis continues to dwindle, other clan‐ and region‐based actors will become more salient as national debates over federalism, the decentralization of governance mechanisms beyond Mogadishu and the place of clannism will occupy centre stage. As a consequence, AMISOM's principal roles should gradually shift from degrading Al‐Shabaab towards a broader stabilization agenda: encouraging a national consensus over how to build effective governance structures; developing an effective set of Somali National Security Forces; and ensuring that the Federal Government delivers services and effective governance to its citizens, especially beyond Mogadishu in the settlements recently captured from Al‐Shabaab. As it stands, however, AMISOM is not prepared to carry out these activities. More worryingly, nor is the Somali Federal Government.     

John Marshall Harlan's Political Memoir

Near the end of his life, John Marshall Harlan wrote a number of biographical essays, presumably at the request of his children. Most of the essays relate to his experiences in the Civil War. The essay reprinted here instead recounts Harlan's political career before he joined the Supreme Court. Although he rarely won any elections and only held a couple of offices, Harlan's political odyssey is significant in that it shows how his social views were formed. Harlan's transformation from a staunch anti‐abolitionist to a civil‐rights advocate can be viewed as a series of reactions against various opponents as he struggled to find his political identity after the collapse of the Whig party in the 1850s.     

UVB RADIATION DISTRIBUTION IN CANADA DURING 1992 AND 1993

One of the steps leading to an assessment of the biological significance of ozone destruction is to determine the biologically effective ultraviolet radiation (UVB) distribution. The objective of this study is to describe and analyze broadband UVB radiation at 24 locations across Canada, during the period from July 1992 through December 1993. This is the first study of broadband UVB measurements involving such a large number of UVB measuring instruments. Quantitative characteristics and statistical analysis of the surface UVB radiation in Canada with respect to ozone amount, as well as cloudiness, are presented. The results indicate higher UVB irradiance in the second half of 1992, compared with the same period in 1993. Among all the locations, Toronto received the greatest dose of UVB radiation in 1993. Excluding Yellowknife, due to its northernmost location (larger zenith angles), Ste-Agathe, Quebec received the smallest dose. Unusually high UVB fluxes were found to occur in March 1993 over eastern Canada. A study of the correlation of UVB radiation with total ozone and cloud opacity was carried out for most of the locations. The results suggest that other meteorological parameters have a significant impact on the ultraviolet levels.
