Dispossessing bare life: Towards a theoretical framework for examining power relations through economic development at the 2010 FIFA World Cup in South Africa

In the past twenty years an increasing number of Global South nations have vied for the rights to host prestigious and expensive sport mega events. This trend requires significant reflection given the enormous economic costs of these events, which often produce little capital gain for the host nation (Whitson & Horne, 2006). Furthermore, sport mega events are often utilized for their symbolic capital (Belanger, 2009), which sometimes manifests through forcing people from their land for the sake of “beautification” (Davis, 2006). In this project, then, I asked how technologies of power were utilized by FIFA, corporate stakeholders, and the South African government to control people who were marginal to, or impeded the success of, the World Cup in Nelspruit, South Africa. This project consisted of two parts: the first involved constructing a theoretical framework for better understanding power as it operates through sport mega events in general. To this end I employed Marxian notions of the ordering of physical space, Foucauldian conceptions of sovereignty and governmentality, and Agamben’s (1998) state of exception to determine how particular bodies are constituted and controlled through sport mega events. In the second part, I applied this theoretical framework to the events in South Africa to better elucidate how people became displaced and killed because of the 2010 FIFA World Cup. I used South African popular news and documentaries as empirical evidence and conducted a discursive analysis of said news media. Through this coverage it became apparent that the mega event created the conditions in which new forms of rogue sovereign partnerships could arise through a historically and spatially contingent process of capitalism. The rogue sovereigns’ para-juridico-political orders, the discourses and practices of accumulation by dispossession as a tactic and effect of govermentality, and other historical non-capital subjectivities such as racial identity, all contributed to constituting Agamben’s state of exception in which people could be displaced, killed or left to die in the events surrounding the World Cup.

Oscillator strengths for transitions in C-like ions between K XIV and Mn XX

Energy levels and oscillator strengths (transition probabilities) have been calculated for transitions among 46 fine-structure levels of the (1s(2)) 2s(2) 2p(2), 2s2p(3),2p(4), 2s(2)2p3s, 2s(2) 2p3p and 2s(2)2p3d configurations of C-like K XIV, Sc XVI, Ti XVII, V XVIII, Cr XIX and Mn XX using the GRASP code. Configuration interaction and relativistic effects have been included while generating the wavefunctions. Calculated values of energy levels agree within 3% with the experimentally compiled results, and the length and velocity forms of oscillator strengths agree within 20% for a majority of allowed transitions.

The trade unions membership dynamics and union members’ trajectories

This text presents an analysis of aggregated membership’s dynamics for Spanish trade unions, using ECVT data, as well as union memberships’ trajectories, or members’ decisions about joining the organization, permanency and responsibilities, and subsequent attrition. For the analysis of trajectories we make use of information of the records of actual memberships and the record of quitting of CCOO, and of a survey-questionnaire to a sample of leavers of the same union. This study allows us to confirm a linkage between the decision and motivations to become union member, to participate in union activities, the time of permanency, and the motives to quit the organization. We also identify five types of union members’ trajectories, indicating that, far from views that assert a monolithic structure, unions are complex organizations.

THE IMPACT OF VIRUS INFECTION IN DEREGULATION OF CYTOKINE PRODUCTION UPON SECONDARY BACTERIAL INFECTION

Dendritic cells (DCs) secrete cytokines such as interleukin-23 (IL-23) when stimulated with certain Toll-like receptor (TLR) agonists and infected with pathogens such as P. aeruginosa. IL- 23 is a proinflammatory cytokine that plays a critical role in the proliferation and differentiation of the IL-17 producing Th17- CD4 T helper cells. The lack of efficient cytokine production from antigen-presenting cells, such as DCs, can impact CD4 differentiation and thus impair the immune responses against pathogens. Clearance of some bacterial infections, such as Klebsiella pneumonia and Listeria monocytogenes has been shown to be dependent on the induction of IL-23 and therefore, deregulation of these cytokines as a direct result of virus infection may impede immune responses to secondary infections. Here, an inhibition of TLR ligand or P. aeruginosa-induced IL- 23 expression in Lymphocytic Choriomeningitis Virus (LCMV)-infected bone marrow-derived dendritic cells (BMDCs) has been demonstrated, indicating that an important function of these cells is disrupted during virus/bacterial coinfection. While production of TNF-α was unaffected in LPS stimulated cells, TNF-α was significantly inhibited in bacterium infected cells by LCMV. Type I IFN in LPS or LCMV infected cell was not detected and therefore, ruling out the possibility of cytokine suppression by Type I IFN. The production of IL-10 was high in BMDCs infected with LCMV and stimulated with LPS or bacteria. Analysis of multiple cytokines produced in this coinfection model demonstrated that LCMV infection impacts specific cytokine production upon LPS or bacterium infection, which may be important for bacterial clearance. This data is important for future immunotherapy use in viral/bacterial coinfection scenarios.
