Gender,feminism and food studies

Policy research and scholarship on food has rapidly increased in recent decades. The attention to ‘gender' within this work appears to signal important practical and academic efforts to mainstream gendered understandings of food consumption, distribution and production into expansive conceptualisations of human security. This article argues that the gender-related work on food has wide-ranging and often troubling political and theoretical foundations and implications. Often growing out of knowledge regimes for managing social crises and advancing neo-liberal solutions, much gender and food security work provides limited interventions into mainstream gender-blind work on the nexus of power struggles, food resources and globalisation. A careful analysis of knowledge production about gender and food is therefore crucial to understanding how and why feminist food studies often transcends and challenges dominant forms of scholarship and research on food security. This article's critical assessment of what food security studies in South Africa has entailed at the regional level and in global terms also focuses on the methodological and theoretical feminist interventions that can stimulate rigorous conceptual, research and practical attention to what has come to be understood as food sovereignty.

Combating Islamist radicalisation in South Africa

Is radical Islamism spreading in South Africa? The answer has to be an emphatic ‘yes’. When discussing issues of radicalisation in Africa, commentators often examine the case of Somalia's al-Shabaab or al-Qaeda's North African franchise, al-Qaeda in the Islamic Maghreb (AQIM). Very little attention is paid to radicalisation amongst South Africa's Muslim population. Yet, there is growing evidence that South Africa has come to play an important role in global jihadi networks, from the provision of safehouses and identity documents to the movement of funds and the existence of paramilitary camps for local and foreign jihadis. This paper aims to briefly examine radicalisation and its attendant sources in the country, as well as seeking ways to combat it utilising lessons learned from other countries. ‘Institutional socialisation’ by means of the sources of radicalisation, as well as the concept of what could be termed ‘the democratisation of jihad’ are discussed. The author also proposes ways to combat radicalisation in South Africa utilising lessons learned from other countries, concluding that issues of radicalisation and deradicalisation have to be dealt with on the part of both government and the South African Muslim community.     

Factors that affect the optimal amount of central control in complex systems

Whereas much of the previous research in complex systems has focused on emergent properties resulting from self‐organization of the individual agents that make up the system, this article studies one vital role of central organization. In particular, four factors are conjectured to be key in determining the optimal amount of central control. To validate this hypothesis, these factors are represented as controllable parameters in a mathematical model. For different combinations of parameter values, the optimal amount of central control is found, either analytically or by computer simulation. The model is shown to provide results that match well with the level of control found across a broad spectrum of specific complex systems. This model also provides general guidelines as to how combinations of these factors affect the desirable level of control and specific guidelines for selecting and evaluating leaders. These results indicate that all of these factors, though not exhaustive, should be considered carefully when attempting to determine the amount of control that is best for a system. © 2008 Wiley Periodicals, Inc.

Business and peace in the Niger Delta: what we know and what we need to know

The global restructuring of state–society relationships driven by neoliberal logic has not only allowed for the taming of the ‘state’, which has paradoxically accentuated its inadequacies, but has also facilitated, for better or for worse, the emergence of business – especially transnational corporations – as a major political force in global governance. Consequently, while the issues of peace and conflict have traditionally been the concern of governments, businesses are now increasingly being expected to make peace and conflict their concern. However, despite claims and counterclaims that businesses can be moneymakers and peacemakers, analyses of the relationship between business and peace remain largely embryonic. This paper seeks to contribute to this emerging business and peace debate by drawing on insights from the Niger Delta conflict to ascertain what we know and what we need to know if businesses are to become peacemakers in conflict zones in Africa.     

自由曲面逆向工程中的区域性再设计方法

针对自由曲面逆向工程的再设计，提出了区域性再设计方法。此方法的思想是通过调整1个控制点，使得一定区域内的多个控制点按照某种规律随之变化，从而可以实现曲面再设计的要求。基于此思想，给出了区域性再设计方法的理论推导，并进行了实例仿真验证。

Military Maladaptation: Counterinsurgency and the Politics of Failure

Tactical learning is critical to battlefield success, especially in a counterinsurgency. This article tests the existing model of military adaption against a ‘most-likely’ case: the British Army’s counterinsurgency in the Southern Cameroons (1960–61). Despite meeting all preconditions thought to enable adaptation – decentralization, leadership turnover, supportive leadership, poor organizational memory, feedback loops, and a clear threat – the British still failed to adapt. Archival evidence suggests politicians subverted bottom-up adaptation, because winning came at too high a price in terms of Britain’s broader strategic imperatives. Our finding identifies an important gap in the extant adaptation literature: it ignores politics.     

How do sources of traditional legitimacy constrain popular uprisings? The case of the Kingdom of Swaziland

ABSTRACT

Research concerning authoritarian stability and peace usually investigates co-optation and repression. Recently, several studies argue that traditional legitimacy is also important for stability in monarchies. However, existing research rarely considers how legitimacy constrains rebellions and help the royal family to stay in power. Hence, this article explores the causal links between sources of traditional legitimacy and absence of uprisings. The study investigates the relationship with a case study of the Kingdom of Swaziland. In line with my expectations, I find a causal relationship between sources of traditional legitimacy and absence of popular uprisings. First, the royal family actively uses traditional legitimacy to justify their rule. Second, the Afrobarometer indicates that the Swazi people trust the King more than citizens in other African countries trust their head of state. Third, opposition actors have limited opportunities to mobilize the broader population against the monarchy. Fourth, traditional legitimacy dampens ongoing protests and thereby hinders their escalation into popular uprisings or political violence. Repression is clearly an important explanation for limited rebellion in Swaziland, but this article shows that also traditional legitimacy sources play a role.
