Responding to Gender-Based Rejection: Objecting Against Negative and Disproving Positive Intergroup Differentiation

Copyright © 2013 SAGE Publications. Author's draft version; post-print. Final version published by Sage available on Sage Journals Online http://online.sagepub.com/We examined whether women (N = 87) who are exposed to blatant discrimination show different responses depending on whether they are rejected with reference to positively (“this is something for men”) or negatively (“this is nothing for women”) phrased intergroup differentiation. Based on current insights on responses to discrimination, we predicted and found that those who are exposed to negative differentiation will tend to object to those who rejected them, while positive differentiation is more likely to induce efforts to disprove the validity of the rejection. Female participants facing negative differentiation objected against the discriminatory nature of their rejection and showed cardiovascular reactivity more indicative of threat (and less of challenge) than participants in the positive differentiation condition. In addition, positive differentiation caused participants to disprove the validity of these group-based expectations by claiming the possession of relatively more masculine (and less feminine) traits

THE POLITICAL ECONOMY OF FOOD PRICE INFLATION IN SOUTH AFRICA

This paper reports on a study that investigated the increase in food prices in South Africa. It is set against the scenario of an increasing inflation rate since September 2001. The June 2002 STATSSA figures estimated the annual inflation rate (CPIX) at 8.8% with food inflation being the major contributor with an annual increase of 14%. The high unemployment and poverty rate in South Africa has already lead to concerns about the negative impact of these increases on the cost of living for the poorest. In this paper we show that the sharp depreciation of the exchange rate towards the end of 2001 had a major impact on the producer price of maize one of the key agricultural commodities because of its role as a staple food and as an input in the production of white and red meat and other animal products.Demand and Price Analysis, Political Economy,

Intergroup status differences as challenge or threat: The role of legitimacy

Based on social identity theory (Tajfel & Turner, 1979) we examined the motivational consequences of intergroup status differences as a function of the legitimacy of these differences. Motivational responses were conceptualized in terms of challenge and threat and operationalized by their cardiovascular markers, as described by the biopsychosocial model of challenge and threat (BPS-CT; Blascovich & Mendes, 2010). Participants (N = 104) were categorized in minimal groups. Group status and status legitimacy were manipulated in the context of an intergroup competition. High status elicited relatively more challenge (less threat) when status differences were legitimate than when they were illegitimate. Low status elicited relatively less threat (more challenge) when status differences were illegitimate than when they were legitimate. Cardiovascular reactivity in line with challenge mediated performance during the competition. Results are discussed in terms of the relationship between social status and stress, and the BPS-CT as novel and useful motivational framework for studying social identity processes.Social decision makin

Combinatorics of Open Covers VI: Selectors for Sequences of Dense Sets

We consider the following two selection principles for topological spaces: [Principle 1:] { For each sequence of dense subsets, there is a sequence of points from the space, the n-th point coming from the n-th dense set, such that this set of points is dense in the space; [Principle 2:]{ For each sequence of dense subsets, there is a sequence of finite sets, the n-th a subset of the n-th dense set, such that the union of these finite sets is dense in the space. We show that for separable metric space X one of these principles holds for the space C_p(X) of realvalued continuous functions equipped with the pointwise convergence topology if, and only if, a corresponding principle holds for a special family of open covers of X. An example is given to show that these equivalences do not hold in general for Tychonoff spaces. It is further shown that these two principles give characterizations for two popular cardinal numbers, and that these two principles are intimately related to an infinite game that was studied by Berner and Juhasz

The combinatorics of the Baer-Specker group

Denote the integers by Z and the positive integers by N. The groups Z^k (k a natural number) are discrete, and the classification up to isomorphism of their (topological) subgroups is trivial. But already for the countably infinite power Z^N of Z, the situation is different. Here the product topology is nontrivial, and the subgroups of Z^N make a rich source of examples of non-isomorphic topological groups. Z^N is the Baer-Specker group. We study subgroups of the Baer-Specker group which possess group theoretic properties analogous to properties introduced by Menger (1924), Hurewicz (1925), Rothberger (1938), and Scheepers (1996). The studied properties were introduced independently by Ko\v{c}inac and Okunev. We obtain purely combinatorial characterizations of these properties, and combine them with other techniques to solve several questions of Babinkostova, Ko\v{c}inac, and Scheepers.Comment: To appear in IJ

How effortful is cognitive control? Insights from a novel method measuring single-trial evoked beta-adrenergic cardiac reactivity

The ability to adjust attentional focus to varying levels of task demands depends on the adaptive recruitment of cognitive control processes. The present study investigated for the first time whether the mobilization of cognitive control during response-conflict trials in a flanker task is associated with effort-related sympathetic activity as measured by changes in the RZinterval at a single-trial level, thus providing an alternative to the pre-ejection period (PEP) which can only be reliably measured in ensemble-averaged data. We predicted that response conflict leads to a physiological orienting response (i.e. heart rate slowing) and increases in effort as reflected by changes in myocardial beta-adrenergic activity (i.e. decreased RZ interval). Our results indeed showed that response conflict led to cardiac deceleration and decreased RZ interval. However, the temporal overlap of the observed heart rate and RZ interval changes suggests that the effect on the latter reflects a change in cardiac pre-load (Frank-Starling mechanism). Our study was thus unable to provide evidence for the expected link between cognitive control and cardiovascular effort. However, it demonstrated that our single-trial analysis enables the assessment of transient changes in cardiac sympathetic activity, thus providing a promising tool for future studies that aim to investigate effort at a single-trial level

Impact of the council of europe resolution on quality and safety assurance requirements for medicinal products prepared in pharmacies for the special needs of patients

Introduction and objective: The regulation of pharmacy preparations, especially for standards for quality assurance and safety, is not harmonised across Europe and falls under the national competencies of individual states. There are concerns about quality control and safety for the medicinal products made in pharmacies, which is widespread in European countries. There are, however, good reasons to continue this practice, which is able to tailor preparations to the specific needs of a particular patient or patient group and to provide a supplementary source of supply when an industrially manufactured product, which is authorised for marketing is not available or when there are temporary shortages of licensed medicines. In seeking to provide guidelines for legislation and acting on the advice of an expert group dealing in pharmaceutical practices, the Committee of Ministers of the Council of Europe passed a resolution in 2011. The Council of Europe Resolution provides authorities and pharmacists with the means to reinforce safety measures for medicinal products prepared in pharmacies and to harmonise quality assurance and safety standards. It dealt with aspects of pharmacy preparation such as quality standards for preparation and distribution, marketing authorisation, product dossiers, labelling, reporting, and safety. In 2013 and 2014 the Committee of Experts carried out a survey to evaluate the impact of the resolution within a cross section of member states,Methods: In the resolution of 2011 the member states were recommended to adapt their legislation in line with its provisions. The survey that was carried out in 2013 and 2014 followed the recommendations in the reso-lution. A questionnaire was made and sent to across section of member states.Results: Among the member states involved, the results of this survey show a clear commitment to imple-ment the recommendations of the resolution.Conclusions: This report presents the results of the survey with a discussion of outstanding issues

Writing about personal goals and plans regardless of goal type boosts academic performance

Academic underachievement is a problem for both our education system and general society. Setting personal goals has the potential to impact academic performance, as many students realize through reflection that studying is a path towards realizing important life goals. Consequently, the potential impact of a brief (4–6 h), written, and staged personal goal-setting intervention on undergraduate academic performance (earned European Credit Transfer and Accumulation System credits) was investigated. Using a time-lagged quasi-experimental design, our model was tested with two first-year university goal-setting cohorts and two control cohorts (total n = 2928). The goal-setting cohorts (n = 698 and 711) showed a 22% increase in academic performance versus the control cohorts (n = 810 and 707). This increase depended on (1) the extent of participation in the 3-stage goal-setting intervention, (2) number of words written in the exercise, and (3) the specificity of students’ goal-achievement plans (GAP). Contrary to goal-setting theory, which necessitates goal-task specificity, the results revealed that it did not matter whether the students wrote about academic or non-academic goals, or a combination of both. Rather, it appeared to be the overall process of writing about their personal goals, the specificity of their strategies for goal attainment, and the extent of their participation in the intervention that led to an increase in their academic performance. This study suggests an important modification to goal-setting theory, namely a potential contagion effect of setting life goals, an academic goal primed in the subconscious, and subsequent academic performance
