Samelewingsdiensleer in hoër onderwys: Afrikaans vir niemoedertaalsprekers

The purpose of the project on community service-learning in curricula was to test the merits of this methodology in a second year Afrikaans (non-mother-tongue) class at university level. Community service-learning provides learners with the empowering opportunity to offer authentic service in and for communities and to be assessed in authentic situations. This structured learning that goes beyond the classroom engages communities in service activities that benefit student teachers as well as communities. The reflection sessions which all of the partners engaged in during and at the end of the semester were a means of identifying areas where improvements could be effected.Keywords: Community Service-learning; Higher Education, case study, Afrikaans for non-mother-tongue speakers; outcomes-based educationThe article is in Afrikaan

Subjektiewl en objektiewe bepaling van die effek van twee metodes van diepvetbraai op die smaaklikheidseienskappe van- beesvleis

M. longissimus dorsi- en semitendinosusskywe is voigens twee diepvetbraaimetodes gaargemaak. Die vet- en voginhoud van rou en gaar skywe is bepaal. Die vet is verder ontleed met betrekking tot vetsuurverspreiding. Evalueringvan die eetkwaliteit is deur 'n opgeleide proepaneel gedoen. Diepvetbraai onder druk het sagter skywe met 'n !aer vetinhoud as konvensionele diepvetbraai gelewer. Die evaluering deur die proepaneel was in ooreenstemming met hierdie bevindings. Die metode van diepvetbraai het geen invloed op die vetsuurverspreiding gehad nie, maar daar was 'n betekenisvolle toename in die hoeveelheid linoleiensuur wat hoofsaaklik toe te skryf is aan die hoe linoleiensuurinhoud van die gaarrnaakmedium.English Title: Subjective and objective assessment of the influence of  two methods of deepfat frying on the palatability characteristics of beefEnglish AbstractM. longissimus dorsi and M. semitendinosus steaks were cooked by two methods of deepfat frying. Steaks were analyzed raw and cooked for lipid and moisture content. The extracted lipids were further analyzed to determine fatty acid distribution. A trained taste panel evaluated the eating quality of the steaks. Pressurized deepfat frying yielded more tender steaks with lower fat content than conventionally fried steaks. Taste panel evaluations were in agreement with these findings. The methods of frying had no effect on the free fatty acid distribution, there was however, a significant increase in linoleic acid, mainlydue to the high linoleic acid content of the cooking medium

The ‘coming-out’ of a hero: The character of Esther in LXX-Esther revisited

The account of the hero is often depicted as a narratological journey which, with reference to the ground-breaking work of Campbell (2008), is referred to as the monomyth. The basic outline of all monomyths is an account of how a hero embarks on a journey, meets a major crisis and then returns back home altered in some way. This change does not only benefit the hero but is also to the advantage of the community that he or she hails from. This study examines the possibility that the story of Esther fits the prerequisites of a monomyth and argues that the additions (Additions A, B, C, D, E and F) to LXX-Esther give emphasis to and reinforce the impression of the hero-myth underlying the story. The therapeutic and transforming qualities of the hero story, narrated in LXX-Esther, are examined in more detail. It is concluded that this hero story fulfils two basic human functions: an epistemic function and a restorative function. Contribution: This article contributes to HTS Teologiese Studies/Theological Studies’s’ contested Historical Thought and Source Interpretation by focusing on textual and hermeneutical studies, and narratives behind the Abrahamic religion as expressed in the Hebrew Scriptures, Apocrypha, Pseudepigrapha and the Septuagint

A pre and post election comparison of the affirmative action policies of South African listed companies

A pre and post election comparison of the affirmative action policies of South African listed companiesAffirmative action can be described as the enforced empowerment and occupational advancement of historically disadvantaged groups. These disadvantaged groups can only be empowered and occupationally advanced once opportunities for occupational advancement, personal development and an improved quality of life have been created. In this article the influence of the first democratic election of 27 April 1994 on affirmative action policies o f the South African companies listed on the Johannesburg Stock Exchange is investigated. Subsequent to the election a marked increase in the percentage o f listed companies applying affirmative action policies has been observed in respect of occupational advancement and personal development. An increase in the quality of life benefits and facilities made available to all employees is not, however, always evident

Fine‐scale measurement of diffusivity in a microbial mat with nuclear magnetic resonance imaging

Noninvasive 1H‐nuclear magnetic resonance (NMR) imaging was used to investigate the diffusive properties of microbial mats in two dimensions. Pulsed field gradient NMR was used to acquire images of the H2O diffusion coefficient, Ds, and multiecho imaging NMR was used to obtain images of the water density in two structurally different microbial mats sampled from Solar Lake (Egypt). We found a pronounced lateral and vertical variability of both water density and water diffusion coefficient, correlated with the laminated and heterogeneous distribution of microbial cells and exopolymers within the mats. The average water density varied from 0.5 to 0.9, whereas the average water diffusion coefficient ranged from 0.4 to 0.9 relative to the values obtained in the stagnant water above the mat samples. The apparent water diffusivities estimated from NMR imaging compared well to apparent O2 diffusivities measured with a diffusivity microsensor. Analysis of measured O2 concentration profiles with a diffusion‐reaction model showed that both the magnitude of calculated rates and the depth distribution of calculated O2 consumption/production zones changed when the observed variations of diffusivity were taken into account. With NMR imaging, diffusivity can be determined at high spatial resolution, which can resolve inherent lateral and vertical heterogeneities found in most natural benthic systems

A Killing Disease Epidemic Among Displaced Sudanese Population Identified as Visceral Leishmaniasis.

A fatal disease epidemic affected the Bentiu area in southern Sudan and led to a mass migration of the Nuer tribe searching for treatment. The initially available information revealed a high mortality rate due to a possible occurrence of tuberculosis, malaria, enteric fever or visceral leishmaniasis (VL). Serological screening of 53 of the most severely affected patients in an enzyme-linked immunosorbent assay (ELISA) or an improved direct agglutination test (DAT) revealed positivity for VL. In 39 of those patients, diagnosis was confirmed by identification of Leishmania donovani amastigotes in lymph node or bone-marrow aspirates. In a total of 2714 patients observed, 1195 (44.0%) had clinical symptoms suggesting VL: DAT positive titers (1:3200-greater than or equal to 1:12800) were obtained in 654 (24.1%), of whom 325 were confirmed parasitologically. Forty-two VL cases died before or during treatment, giving a mortality rate of 6.4%. Among the intercurrent infections diagnosed in the VL population (654), respiratory involvements (31.7%) and malaria (10.7%) were most prevalent. With the exception of four (0.6%), all other VL patients (509) responded readily to sodium stibogluconate. The factors initiating the outbreak are discussed. Malnutrition and nomadic movements to potential VL endemic areas appeared to be the most important. HIV infection as a possible predisposition seemed remote considering the clinical and epidemiological similarity to VL occurring in East Africa, adequate humoral response in DAT, and immediate positive response to specific anti-Leishmania chemotherapy

Predicting work performance through selection interview ratings and psychological assessment.

The aim of the study was to establish whether selection interviews used in conjunction with psychological assessments of personality traits and cognitive functioning contribute to predicting work performance. The sample consisted of 102 managers who were appointed recently in a retail organisation. The independent variables were selection interview ratings obtained on the basis of structured competency-based interview schedules by interviewing panels, five broad dimensions of personality defined by the Five Factor Model as measured by the 15 Factor Questionnaire (15FQ+), and cognitive processing variables (current level of work, potential level of work, and 12 processing competencies) measured by the Cognitive Process Profile (CPP). Work performance was measured through annual performance ratings that focused on measurable outputs of performance objectives. Only two predictor variables correlated statistically significantly with the criterion variable, namely interview ratings (r = 0.31) and CPP Verbal Abstraction (r = 0.34). Following multiple regression, only these variables contributed significantly to predicting work performance, but only 17.8% of the variance of the criterion was accounted for
