Research as a Learning Experience: A Phenomenological Explication

A phenomenological method was employed to explore the learning experiences of seven honours psychology learners who have completed research projects. The research event was experienced as a learning adventure, a period of personal growth, and also lead to a strong appreciation of the differences between doing research in practice and research as described in texts. They regarded time management and problem solving skills as important prerequisites to successful research. Findings provide guidelines for academics involved in the research training of learners and are a useful source of information, to provide insight into and alert learners to the challenges of research

Prevalence, socio-demographic risk factors and consequences of exposure to violence among adolescents in the Macassar community

Thesis (MA)--University of Stellenbosch, 2002.ENGLISH ABSTRACT: The goals of this study were to determine (1) the prevalence of exposure to non-sexual interpersonal violence in a random sample ru=203) of adolescents (14-20 years) from a disadvantaged, relative low socio-economic coloured community, (2) the prevalence ratio of the number of participants who were only witnesses (witnesses) versus the number who were victims (of which some might occasionally also have been witnesses) of non-sexual interpersonal violence, (3) the relationship between certain socio-demographic variables and exposure to non-sexual interpersonal violence in order to identify potential risk factors, and (4) to determine whether victims differed significantly from witnesses with regard to the incidence of post-traumatic stress disorder symptoms (PTSDS) and post-traumatic stress symptoms (PTSS) that do not meet the criteria for post-traumatic stress disorder. The sample consisted of Afrikaans-speaking coloured boys (!!=101) and girls (!!=102) between the ages of 14 and 20 years predominantly from low-income families who lived in municipal sub-economic housing, and who attended two high schools in Macassar. The measuring instruments comprised a customised socio-demograhpic questionnaire, the Child Exposure to Community Violence Scale which measures exposure to non-sexual interpersonal violence as witnesses and victims and the Child and Adolescent PTSD Checklist to assess the incidence ofPTSDS and PTSS. In order to identify potential risk factors for exposure to violence, the relationship between , exposure to violence and the socio-demographic variables of age, gender and presence/absence of a parent as primary caretaker was investigated. It was found that all participants were exposed to non-sexual interpersonal violence as either witnesses (37.9%) or victims (62.1 %). In contrast to findings of other studies, the majority of participants were victims themselves and not only witnesses. Older adolescents (17-20 years) were, in comparison with younger ones (14-16 years), significantly more exposed to non-sexual interpersonal violence as both witnesses and as victims. Older adolescents were thus more at risk for exposure to interpersonal violence. No statistically significant relationship was found between exposure to non-sexual interpersonal violence, either as witness or as victim, and the variables of gender and presence or absence of a parent as a pnmary caregiver. The incidence of reported PTSDS and PTSS, which was significantly related to exposure to non-sexual interpersonal violence, was relatively high. Thirty adolescents (15%) met the diagnostic criteria for post-traumatic stress disorder, 131 (65%) presented with one or more prominent PTSDS and a further 186 (90%) reported PTSS. Victims reported significantly more PTSS than witnesses.AFRIKAANSE OPSOMMING: Die doelstellings van hierdie studie was om (1) die voorkoms van blootstelling aan nieseksuele interpersoonlike geweld by 'n ewekansige steekproef Ct:l:=203) adolessente (14 tot 20 jaar oud) van twee plaaslike hoërskole in 'n benadeelde, relatief lae sosio-ekonomiese Kleurlinggemeenskap te bepaal, (2) die voorkomsratio van die aantal deelnemers wat slegs waarnemers was (waarnemers) versus die aantal wat slagoffers was (van wie sommige per geleentheid ook waarnemers kon gewees het) van nie-seksuele interpersoonlike geweld te bepaal, (3) die verband tussen sekere sosio-demografiese veranderlikes en blootstelling aan nie-seksuele interpersoonlike geweld te bepaal ten einde potensiële risiko-faktore te identifiseer, en (4) om vas te stelof waarnemers beduidend van slagoffers verskil het ten opsigte van die voorkoms van post-traumatiese-stresversteuring-simptome (PTSVS) en post-traumatiese-stres-simptome (PTSS) wat nie voldoen aan die kriteria van posttraumatiese- stresversteuring nie. Die steekproef het bestaan uit Afrikaanssprekende kleurlingseuns (n= 101) en -dogters (n=102) tussen 14 en 20 jaar oud uit oorwegend lae-inkomste gesinne in sub-ekonomiese munisipale behuising en wat leerders was aan twee hoërskole in Macassar. Die meetinstrumente het 'n doelmatige sosio-demografiese vraelys, die Child Exposure to Community Violence Scale om blootstelling aan nie-seksuele interpersoonlike geweld as waarnemers en as slagoffers te meet, en die Child Adolescent PTSD Checklist om die voorkoms van PTSVS en PTSS te bepaal, ingesluit. Ten einde potensiële risiko-faktore vir blootstelling aan geweld te identifiseer, is die verband tussen blootstelling aan geweld en die sosio-demografiese veranderlikes van ouderdom, geslag en die teenwoordigheid/afwesigheid van 'n ouer as pimêre versorger ondersoek. Daar is bevind dat al die deelnemers, hetsy as waarnemers (37.9%) of slagoffers (62.1 %), aan nie-seksuele interpersoonlike geweld blootgestel was. In teenstelling met die bevindings van ander studies was die meerderheid van die deelnemers self slagoffers van geweld en nie net waarnemers daarvan nie. Ouer adolessente (17-20 jaar) was, in vergelyking met jongeres (14 tot 16 jaar), beduidend meer aan interpersoonlike geweld, beide as waarnemers en as slagoffers, blootgestel. Ouer adolessente was dus 'n hoër risikogroep vir blootstelling aan interpersoonlike geweld. Geen statisties beduidende verband is tussen die veranderlikes van geslag en die teenwoordigheid van 'n ouer as primêre versorger en blootstelling aan nie-seksuele interpersoonlike geweld as óf slegs waarnemer óf slagoffer gevind nie. Die voorkoms van gerapporteerde PTSVS en PTSS, wat 'n beduidende verband met blootstelling aan nie-seksuele interpersoonlike geweld getoon het, was relatief hoog. Dertig adolessente (15%) het voldoen aan die diagnostiese kriteria van post-traumatiese stresversteuring, 131 (65%) het met een of meer prominente PTSVS gepresenteer en 'n verdere 186 (90%) het PTSS gerapporteer. Slagoffers het beduidend meer PTSVS en PTSS as waarnemers gerapporteer

African Water: Supporting African involvement in the EU Framework Programme.

Water researchers in developing countries have yet to take full advantage of the funding and collaborative research opportunities presented by the EU Framework Programme. There are a variety of reasons for this, such as insufficient information and a lack of previous experience. The African Water initiative aims to increase the involvement of African water researchers through a range of activities including communication and dissemination, capacity building and development, and complementary initiatives. The project has demonstrated that there is a demand for such sector-specific support activities. However, African Water is a small component of a much larger process of partnership between the developed and the less-developed countries of the world, involving many different European and African organisations working across political, institutional and technical domains, and complementing the wide range of actions already being undertaken

Antiviral treatment for Bell's palsy (idiopathic facial paralysis)

BACKGROUND: Antiviral agents against herpes simplex virus are widely used in the treatment of idiopathic facial paralysis (Bell's palsy), but their effectiveness is uncertain. Significant morbidity can be associated with severe cases. OBJECTIVES: This review addresses the effect of antiviral therapy on Bell's palsy. SEARCH STRATEGY: We updated the search of the Cochrane Neuromuscular Disease Group Trials Register (December 2008), MEDLINE (from January 1966 to December 8 2008), EMBASE (from January 1980 to December 8 2008) and LILACS (from January 1982 to December 2008). SELECTION CRITERIA: Randomized trials of antivirals with and without corticosteroids versus control therapies for the treatment of Bell's palsy. DATA COLLECTION AND ANALYSIS: Twenty-three papers were selected for consideration. MAIN RESULTS: Seven trials including 1987 participants met the inclusion criteria, adding five studies to the two in the previous review.Incomplete recovery at one year. There was no significant benefit in the rate of incomplete recovery from antivirals compared with placebo (n = 1886, RR 0.88, 95% CI 0.65 to 1.18). In meta-analyses with some unexplained heterogeneity, the outcome with antivirals was significantly worse than with corticosteroids (n = 768, RR 2.82, 95% CI 1.09 to 7.32) and the outcome with antivirals plus corticosteroids was significantly better than with placebo (n = 658, RR 0.56, 95% CI 0.41 to 0.76).Motor synkinesis or crocodile tears at one year. In single trials, there was no significant difference in long term sequelae comparing antivirals and corticosteroids with corticosteroids alone (n = 99, RR 0.39, 95% CI 0.14 to 1.07) or antivirals with corticosteroids (n = 101, RR 1.03, 95% CI 0.51 to 2.07).Adverse events.There was no significant difference in rates of adverse events between antivirals and placebo (n = 1544, RR 1.06, 95% CI 0.81 to 1.38), between antivirals and corticosteroids (n = 667, RR 0.96, 95% CI 0.65 to 1.41) or between the antiviral-corticosteroid combination and placebo (n = 658, RR 1.15, 95% CI 0.79 to 1.66). AUTHORS' CONCLUSIONS: High quality evidence showed no significant benefit from anti-herpes simplex antivirals compared with placebo in producing complete recovery from Bell's palsy. Moderate quality evidence showed that antivirals were significantly less likely than corticosteroids to produce complete recovery.</p

Opportunities for strengthening provider-initiated testing and counselling for HIV in Namibia

This short report identifies enablers and barriers to the uptake of provider-initiated testing and counselling for HIV (PITC) in Namibia and identifies key opportunities for strengthening this vital aspect of the national HIV response. We explored this through facility mapping, register reviews and qualitative methods including focus group discussions and in-depth interviews. Four health facilities (clinics and hospitals) in two regions were included in the study. We identified that PITC in Namibia was largely delivered by lay counsellors operating in designated rapid testing rooms located in health facilities and found a large number of missed opportunities for HIV testing through this model. Nurses did not see it as an integral part of their role, were not aware of HIV testing and counselling policy, felt inadequately trained and supported, and experienced staffing shortages. Institutional issues also acted as barriers to nurses performing or initiating discussions about PITC. Wider dissemination and implementation of policy, increasing privacy of consultation spaces and community sensitisation are simple measures that represent opportunities for strengthening this response and ensuring that symptomatic individuals who are unaware of their HIV status do not fall through the net

Annotated checklist of the birds of Banhine National Park, Southern Mozambique

Banhine National Park, situated in Gaza Province, Mozambique, covers an area of 700 000 ha of near-pristine landscapes. Within the park borders, 11 plant communities have been identified, which can be broadly grouped into five major landscape types, viz. wetland, grassland, Mopane, sandveld and Androstachys landscapes. These landscapes support a wealth of bird species, with 318 species being confirmed in the park to date and many additional species believed to still occur in the park. Of the species recorded to date, 76 are significant range expansions for southern Mozambique, six species were previously subject to confirmation from southern Mozambique, two species have not previously been recorded from southern Mozambique and nine species are considered to be regionally or globally threatened. Of the five landscapes, the wetland boasts by far the greatest diversity and greatest numbers of species, and is probably the most important, and most threatened, landscape in the park

Identification of Mgenia fuscovaria (Stål)(Hemiptera: Cicadellidae), a vector of aster yellows disease on grapevines in South Africa, and differentiation from Mgenia angusta (Theron) by nucleotide sequences of the mitochondrial cytochrome oxidase I (cox1) gene

Aster yellows phytoplasma (AY), only recently reported in South Africa and still limited in its distribution in the country, causes a serious disease of grapevine. A leafhopper, Mgenia fuscovaria (Stål)(Hemiptera: Cicadellidae), was shown to transmit AY to grapevine (Vitis vinifera L.) locally. A second Mgenia species, identified as Mgenia angusta (Theron), has also been found in vineyards in South Africa but has not been shown to transmit AY. M. angusta is morphologically similar to M. fuscovaria, but does differ regarding the size of the male sex organ and in the number of teeth of the blades making up the ovipositor. In this study, we determined the nucleotide sequence of the mitochondrial cytochrome oxidase I gene (cox1),commonly used in insect bar-coding, of a number of specimens of males, females and nymphs of both M. fuscovaria and M. angusta. No differences were observed between the cox1 sequences of the male, female and nymph specimens putatively assigned to any specific species, but some nucleotide sequence differences were observed between specimens of M. fuscovaria and M. angusta. These differences, however, were insufficient to allow the development of PCR systems specific to each species

A frightening view on schizophrenia. Combining fear conditioning and ketamine administration to investigate emotional blunting in an animal model of schizophrenia

De negatieve symptomen van schizofrenie zijn gerelateerd aan het leren en verwerken van emoties zoals angst. Promovenda Charmaine Pietersen onderzocht of deze emoties nog geleerd en verwerkt kunnen worden bij een (sterk) verminderde functie van het glutama­terge neurotransmitter systeem in de hersenen. De resultaten van het onderzoek ondersteu­nen eerdere hypotheses over de negatieve symptomen van schizofrenie.

Spirituality as “good Christian citizenship” in the pastoral epistles?

Dibelius, in his commentary on the Pastoral Epistles, suggested that they represented a way-of-being in the world resulting from the delay of the parousia. As such they advocate a form of spirituality which can best be described as &ldquo;good Christian citizenship&rdquo;. This paper, drawing on both Taylor&rsquo;s understanding of the &ldquo;social imaginary&rdquo; and Waaijman&rsquo;s understanding of spirituality, examines Dibelius&rsquo; contention by revisiting the concept of eusebeia (godliness/piety), which is prevalent in the Pastorals, in the light of the lived experience of pagans, Jews and Christians in first-century Ephesus

Multiple criteria decision analysis (MCDA): A tool to support sustainable management of groundwater resources in South Africa

The National Water Act (NWA) of 1998 has been promulgated in South Africa to support the attainment of sustainable water resource use. Before the Act was promulgated, landowners were entitled to unlimited groundwater use. The Act rectified this anomaly; however, the practical application of sustainable development concepts in groundwater resource management will be complex. A multiple criteria decision analysis (MCDA) approach was used to identify critical alternative courses of action and to develop a decision-making framework for sustainable groundwater management. Through applying the decision model described in this paper a number of strategies have been proposed which are aligned to the legislative requirements of the NWA. Water SA Vol. 32(2) 2006: pp.119-12
