Creating a learning culture in rural schools via educational satellite television broadcasts

Abstract

Globalisation is increasingly placing greater pressure on economies of countries to become competitive and to develop higher levels of skills. In order to compete effectively on a global level, education and development must be based on a good foundation. Although formal education in South Africa is presently reaching the majority of children between the ages of seven and fifteen years, actual educational attainment is low. According to the Third International Mathematics and Science Study, South African pupils performed poorly in Mathematics and Physical Science compared to other participating countries.

This low attainment could be addressed by stimulating a learning culture through the medium of telematics. There have been a number of such nationwide initiatives aimed at transforming the country into a 'knowledge-based society' through the use of ICTs. One such initiative is the University of Pretoria's 'TeleTuks' educational satellite broadcasts to schools.

This article concentrates on the benefits of tele-education for schools participating in TeleTuks as perceived by teachers and by learners. This study was also done to determine to what extent schools are able to participate in the various ICT-related options available; and what problems participating schools are experiencing. It was found that satellite TV is effective in supplementing classroom education by fostering an interactive learning culture, although it has not been utilised and implemented widely enough.     

The Impact of Voter Evaluations of Leaders’ Traits on Voting Behaviour: Evidence from Seven European Countries

This article aims to examine how the evaluation of party leaders’ traits influences voting behaviour. The work incorporates data from election studies across seven countries with different social contexts (Portugal, Spain, Ireland, Germany, United Kingdom, Italy and Hungary). Characteristics of leaders were placed into two groups: competence and warmth, in accordance with the stereotype content model and relevant studies on evaluations of leaders’ traits. Since different personality traits were evaluated within each country, the analysis was based on the two aforementioned dimensions and the political ideology of the leader. Multiple sequential binary logistic regression models were performed to analyse the predictive power of competence and warmth on voting behaviour, controlling for socio-demographic and political ideology variables of voters. Results reinforce the personalisation of politics theory, showing the relevance of leaders’ warm personality traits. As for the competence dimension, it was proven to be decisive only with regard to left-wing party leaders.     

A New US-Sino Space Relationship: Moving Toward Cooperation 1

Since the late 1990's the United States has maintained a strict policy of no cooperation with China on space activities. The reasons for that are several, including the desire to inhibit the development of dual-use technology considered potentially threatening to the United States and political reluctance to work with a communist country. Increasingly, however, it has become clear that policy is not constraining China from dual-use technology development and that the policy overall may be detrimental to U.S. security interests. Therefore a policy change, from a realistic consideration of circumstances, must be considered.     

BIS/BAS Variables as Moderators of the Rumination-Intimate Partner Violence Link

Although cognitive rumination is related to violence perpetration, not all people who ruminate become violent. Four personality variables—impulsivity, anxiety, anger-in, anger-out—were tested as possible moderators of the link between the tendency to ruminate and the frequency of intimate partner violence (IPV). Variables related to the Behavioral Activation System (anger-out and impulsivity) were predicted to strengthen the rumination-IPV link; whereas measures related to the Behavioral Inhibition System (anger-in and anxiety) would suppress this link. As predicted, anger-out, anger-in, and impulsivity moderated the relation between rumination and IPV. No evidence was found for suppressor variables. Thus, appetitive drives appear to amplify the effect of rumination on violence. Clinically, therapeutic techniques that address rumination, anger, and impulsivity may help to reduce IPV risk.     

Self‐Embedding Behavior in Adults: A Report of Two Cases and a Systematic Review

Self‐embedding behavior (SEB) is the repeated insertion of sharp objects, such as needles or pins, into the soft tissues of abdomen, limbs, and other body parts. In this study, two cases of SEB were reported and the scientific worldwide literature reviewed. Thirty‐two cases of SEB were identified through systematic searches in the main bibliographic databases. Mean age was 35 years (SD = 8.97). Just over two‐thirds of the patients were female. Although the number of embedded objects could be as high as 200, major clinical and surgical complications were uncommon and mortality was null. Patients with SEB presented three major diagnoses: psychotic (25%), personality (21.9%), and factitious (28.1%) disorders. The practice of SEB largely went undetected as the patients themselves did not bring it to the attention of family members or physicians and usually denied they have engaged in SEB. A high level of suspicion is required to avoid a missed diagnosis.     

Forensic DNA analysis on microfluidic devices: a review

The advent of microfluidic technology for genetic analysis has begun to impact forensic science. Recent advances in microfluidic separation of short-tandem-repeat (STR) fragments has provided unprecedented potential for improving speed and efficiency of DNA typing. In addition, the analytical processes associated with sample preparation--which include cell sorting, DNA extraction, DNA quantitation, and DNA amplification--can all be integrated with the STR separation in a seamless manner. The current state of these microfluidic methods as well as their advantages and potential shortcomings are detailed. Recent advances in microfluidic device technology, as they pertain to forensic DNA typing, are discussed with a focus on the forensic community.     

Is breast really best? Risk and total motherhood in the National Breastfeeding Awareness Campaign

From June 2004 to April 2006, cosponsored by the U.S. Department of Health and Human Services and the Ad Council, the National Breastfeeding Awareness Campaign (NBAC) warned women that not breast-feeding put babies at risk for a variety of health problems. "You'd never take risks before your baby is born. Why start after?" asked televised public service announcements over images of pregnant women logrolling and riding a mechanical bull. The NBAC, and particularly its message of fear, neglected fundamental ethical principles regarding evidence quality, message framing, and cultural sensitivity in public health campaigns. The campaign was based on research that is inconsistent, lacks strong associations, and does not account for plausible confounding variables, such as the role of parental behavior, in various health outcomes. It capitalized on public misunderstanding of risk and risk assessment by portraying infant nutrition as a matter of safety versus danger and then creating spurious analogies. It also exploited deep-seated normative assumptions about the responsibility that mothers have to protect babies and children from harm and was insufficiently attentive to the psychological, socioeconomic, and political concerns of its intended audience. Critical analysis of the NBAC suggests that future health campaigns would benefit from more diverse review panels and from a greater focus on providing accurate risk information about probabilities and trade-offs in order to enable informed decision making.     

Training for Cultural Production and Management in Brazil

This article aims to contribute to the field of arts management by identifying the need to make cultural production/management an established field of professional practice and training in Brazil, and the challenges of doing so. To accomplish this, we reviewed several publications and we present first a discourse on theoretical texts in relation to the idea of culture and systems of cultural production and then an analysis of arts management publications in Brazil with observations about this field of work. In this article, we address the current paucity of training opportunities of this kind, the extent to which these roles have yet to be professionalized, and indicate, in the conclusion, that this is a matter of increasing importance and concern for cultural policy in Brazil.
