Surplus people and expendable children: The structure of apartheid and the mortality crisis in South Africa
South Africa’s apartheid scheme is considered as a paradigm case for the creation and maltreatment of a putatively surplus population. Both active and passive policies are identified that are utilized to contain the numbers of the black population of the nation. Of particular significance is a strategy of neglect that has led to exceptionally high infant and child mortality rates in the “homelands.” In addition, the South African authorities’ efforts to destabilize neighboring regimes in Angola and Mozambique has had similarly adverse repercussions on mortality rates there.
Technology and the Economic Development of the Tropical African Frontier
The changes [he suggests] in headquarters .organization, the introduction of political ministers, and the increased attention given by governments to matters of economic and social development, each made inappropriate the form of field administration - a modified line and staff model - that had prevailed under the colonial government, and at the same time altered the relationship between headquarters and the field. Moreover, the changes in local government — its democratization, reorganization in the southern half of the country on the model of the ;j English pattern of local government, and declining capacity relative to regional governments - changed the relationship between local government and both the field administration and headquarters, and left the field administrations filling new roles in the regions' administrative systems.
Immune dysfunction following infection with chicken anemia agent and infectious bursal disease virus. II. Alterations of in vitro lymphoproliferation and in vivo immune responses.
To determine the functional impact of alterations in lymphocyte concentrations and ratios following infection with chicken anemia agent (CAA) alone or in combination with infectious bursal disease virus (IBDV) on the immune system of young chickens, in vitro lymphoproliferation assays and in vivo responses to vaccination with several common viral agents were assessed at various time intervals post-inoculation (PI). Concanavalin A (Con A), phytohemagglutinin (PHA) and pokeweed mitogen (PWM) stimulation of splenic lymphocytes (SPL) collected from control birds could not be detected until 10-14 days PI. Infection with CAA was characterized by significantly higher PWM stimulation of SPL at 17 days PI and significantly lower PWM stimulation of peripheral blood lymphocytes (PBL) at 14 days PI, compared with uninfected controls. Concanavalin A and PWM stimulation of SPL was significantly increased in birds inoculated with IBDV alone. Lymphocytes harvested from birds inoculated simultaneously with CAA and IBDV had significantly lower responses. Effects on humoral and cell-mediated immunity following CAA and/or IBDV were determined by evaluating vaccination responses to Newcastle disease virus (NDV), fowl pox virus (FPV) and infectious laryngotracheitis virus (ILTV) during the acute phase of CAA infection (2 weeks PI). Vaccination of birds 2 weeks following CAA infection at 1 day of age resulted in decreased protection against NDV (85.7%) and ILTV (7.1%) challenge compared with protection rates in control birds (100% and 53.3% respectively). Infectious bursal disease virus infection was associated with decreased protection against NDV (60%) only. Concomitant infection at 1 day of age resulted in a greater reduction in NDV challenge protection (33.3%), slightly decreased FPV protection (87.5%), increased numbers of persistent FPV vaccination lesions and increased protection against ILTV challenge (71.4%). Vaccination of birds 2 weeks following CAA infection at 2 weeks of age resulted in slightly decreased NDV humoral antibody, development of persistent FPV vaccination lesions (17%) and increased immunity to ILTV challenge compared with control birds (83.3% vs. 66.7%). Chickens inoculated with IBDV alone displayed a more severe depression in NDV antibody titers and only a slight decrease in ILTV protection. Vaccination following concomitant infection at 2 weeks of age resulted in a higher percentage of FPV persistent vaccination lesions (39%) and greatly enhanced immunity to ILTV challenge (100%).
