Public opinion and the end of apartheid
Julio F Carrión,Stuart J. Kaufman 한국외국어대학교 국제지역연구센터 2018 International Area Studies Review Vol.21 No.2
Why did whites in South Africa come to support the dismantling of the apartheid system that gave them a monopoly of political power? We use a reformulated version of symbolic politics to address this puzzle, showing that white attitudes toward political change were primarily driven by symbolic predispositions regarding race, ideology, party, and specific leaders, as well as various sorts of threat perceptions. Strong attachments to the National Party and de Klerk, low perceptions of threat, more tolerant racial attitudes, and more socially and politically liberal values increased the likelihood of whites supporting policies consistent with the ending of apartheid. We also find that assessments of the economy, both personal and national, have no influence on this attitude. We use South Africa’s Human Sciences Research Council data collected during the crucial 1991–1992 period.

Objective: The present study sought to analyze the influence of Levetiracetam (LEV) in cognitive performance by identifying the changes produced by LEV in reaction time, in neuropsychological assessment of attention and memory and in absolute theta power in frontal activity. Methods: Twelve healthy subjects (5 men and 7 women; mean age, 30.08 years, standard deviation, 4.71) were recruited for this study. The neuropsychological tests: Trail Making Test (A and B), Digit Span (direct and indirect numerical orders/working memory); Stroop test (inhibitory control of attention); Tower of London (planning and decision-making) and a quantitative electroencephalography were applied in 2 different days after and before the participants ingested the capsule of placebo or 500 mg LEV. Results: A two-way-ANOVA was implemented to observe the interaction between conditions (placebo or LEV 500 mg) and moments (pre- and post-ingestion of LEV or placebo). The data were analyzed by the SPSS statistical package (p<0.05). For the neuropsychological parameter, the Trail Making Test (A) was the only test that showed significant difference for condition in the task execution time (p=0.026). Regarding the reaction time in the behavioral parameter, an interaction between both factors (p=0.034) was identified through a two-way-ANOVA (condition versus moment). Electrophysiological measures showed a significant interaction for electrodes: F7, F3, and FZ. Conclusion: The findings showed that LEV promotes an important cognitive enhancement in the executive functions.
