Academic Library Consortia in South Africa : where we come from and where we are heading

The purpose of this article is to give an overview of the establishment of the five academic library consortia in South Africa, their status quo, and a summary of their successes and plans for the future. Although useful information can be found from the consortia Web sites, much of it is no longer current. Similarly, there is limited published literature on the academic library consortia in South Africa. Apart from the sources referenced, the authors therefore relied heavily on an unpublished conference paper by Thomas[reference 1], which included findings gathered during a short survey among the five academic library consortia. In addition, Rowley and Slack[reference 2] and Sekabembe[reference 3] provide useful overviews of the library consortia in South Africa at the time of publication. Further information is available in published and unpublished sources

Some key topographic and material controls on debris flows in Scotland

Debris-flow phenomena were investigated at six study sites across upland Scotland using a combination of laboratory and field-based analyses. In agreement with previous research, higher spatial frequencies of debris-flow paths were measured in areas underlain by coarse-grained intrusive igneous and arenaceous sedimentary bedrocks compared with metamorphic and extrusive igneous geologies. A strong relationship between critical state friction angle of sampled initiation zone soils and spatial frequency of debris-flow paths suggests that this trend is attributable to generally lower shear strengths in sandier hillslope material generated from coarser grained bedrocks. Topographic controls on debris-flow susceptibility are demonstrated by higher numbers of debris-flow paths at sites with persistently steep upper slopes (=30°) and a higher occurrence of potential initiation zones. Strong correlation between debris-flow magnitude and slope length shows that longer mass movements tend to produce higher volumes of material and terminal deposits that travel further at the slope foot. In the cases studied here this reflects greater opportunity for accumulation of fresh material during the transport phase, particularly in the case of long channelized flows. The highest levels of hazard are likely to occur where these topographic and material characteristics conducive to heightened susceptibility and magnitude coincide.</p

A conceptual framework to explore the roles and contributions of Industrial Psychologists in South Africa (Part 1).

This study was aimed at developing a conceptual framework against which the roles and contributions of industrial psychologists in South Africa could be explored. Three widely-used business frameworks – Balanced Score Card, South African Excellence Model and King II Report on Corporate Governance for South Africa – were theoretically integrated to produce a multi-dimensional framework to clarify roles and contributions in a discourse familiar to the business community. The framework was subsequently utilised in a follow-up study involving 23 registered industrial psychologists who were asked to clarify specific roles and contributions within each of the dimensions of the framework

Mental Toughness in South African Youth: Relationships With Forgivingness and Attitudes Towards Risk

Young people are particularly vulnerable to health risk behaviors and interpersonal violence, stimulating scholars’ attention towards identifying factors that may reduce the likelihood that these actions will occur. Associated with positive outcomes in a variety of domains, mental toughness in young people might protect them from engaging in potentially deleterious interpersonal or health-risk behaviors, while potentially promoting positive psychological behaviors. Within this framework, the present study investigated the relationships between mental toughness, attitudes towards physical and psychological risk-taking, and trait forgiveness in a sample of 123 (males = 54, females = 69) South African youth (M age = 23.97 years, SD = 4.46). Univariate and multivariate analyses indicated higher levels of mental toughness were associated with being more forgiving, (η2pηp2 = .036), perceiving physical risk-taking more positively (η2pηp2 = .062), but having more negative attitudes towards psychological risk-taking (η2pηp2 = .036). These findings give credence to mental toughness as a psychological characteristic involved in youth risk-taking perceptions and interpersonal functioning. Future research might explore the integration of mental toughness into the development of future youth risk behavior interventions

Effect of Fungicide Spray Cover on Botrytis Cinerea Infection in Grape Bunches

The effect of fungicide spray cover on Botrytis cinerea infection in grape bunches was determined. Bunches were sprayed at pea size and bunch closure with different volumes of a mixture of fenhexamid and a yellow fluorescent pigment, and the percentage fluorescent pigment coverage on pedicels was determined. Bunches were subsequently dusted with dry airborne conidia of B. cinerea in a settling tower and incubated for 24 h at high relative humidity (98%). Infection was determined by estimating the amount of B. cinerea infections on susceptible bunch parts (pedicel, receptacle and rachis) with isolations onto paraquat (herbicide) and Kerssies (B. cinerea selective) mediums.  Linear regressions for the part × stage combinations of percentage B. cinerea incidence on different bunchparts were fitted on mean coverage levels. An increase in spray cover caused linear reductions in levels of B. cinerea on bunch parts. Higher B. cinerea incidences were recorded at pea size. Furthermore, higher B. cinerea incidences were found on paraquat medium for both stages, than on Kerssies medium. The information gathered from this study will be used to facilitate future determination of minimum effective coverage levels for effective B. cinerea control in grape bunches

Stabilization of a Tailings Dam by De-Watering

The failure of the outer slope of one of the paddocks of a tailings dam, resulted in a significant decrease in the area available for tailings deposition. Overloading of the remaining five paddocks resulted. To maintain the stability of the existing dam whilst construction of new disposal facilities was in progress, three techniques were investigated; horizontal, push-in drains at the dam toe, a rock buttress around the operational paddocks, and vertical de-watering wells installed on the first terrace, or ‘step-back’ of the dam. De-watering wells proved most effective, and 165 wells were installed. A monitoring programme included regular determination of the water level in each well, and the installation of piezometers at selected locations around the dam. These observations were used to optimise the use of the five remaining paddocks, thus ensuring stability of the dam during the transfer of deposition operations to two new tailings dams

Revival of the magnetar PSR J1622-4950: observations with MeerKAT, Parkes, XMM-Newton, Swift, Chandra, and NuSTAR

New radio (MeerKAT and Parkes) and X-ray (XMM-Newton, Swift, Chandra, and NuSTAR) observations of PSR J1622-4950 indicate that the magnetar, in a quiescent state since at least early 2015, reactivated between 2017 March 19 and April 5. The radio flux density, while variable, is approximately 100x larger than during its dormant state. The X-ray flux one month after reactivation was at least 800x larger than during quiescence, and has been decaying exponentially on a 111+/-19 day timescale. This high-flux state, together with a radio-derived rotational ephemeris, enabled for the first time the detection of X-ray pulsations for this magnetar. At 5%, the 0.3-6 keV pulsed fraction is comparable to the smallest observed for magnetars. The overall pulsar geometry inferred from polarized radio emission appears to be broadly consistent with that determined 6-8 years earlier. However, rotating vector model fits suggest that we are now seeing radio emission from a different location in the magnetosphere than previously. This indicates a novel way in which radio emission from magnetars can differ from that of ordinary pulsars. The torque on the neutron star is varying rapidly and unsteadily, as is common for magnetars following outburst, having changed by a factor of 7 within six months of reactivation.Comment: Published in ApJ (2018 April 5); 13 pages, 4 figure

Promoting deeper learning in pharmacy education using team-based learning

Background. The benefit of deep learning compared with surface learning is the ability to retrieve, apply and integrate previously learnt knowledge rather than simply memorising course content most likely to be evaluated during assessments. Team-based learning (TBL) is an educational strategy that echoes the purpose of deeper learning. Objectives. To identify whether TBL as a teaching strategy increases pharmacy students’ understanding of theoretical work. Method. Fourth-year pharmacy students completed a questionnaire consisting of biographical data (gender, age and ethnicity) and 16 questions on their understanding of course content. A total of 183 students (91.5%) participated after giving informed consent that their data may be included in the study. Results. The results indicated that, due to the implementation of TBL in the course, students perceived that they learnt more and made more effort, experienced increased understanding of content, perceived higher knowledge retention, performed better during assessments in the module where TBL was implemented and felt that course outcomes were achieved more easily. Conclusion. TBL as a teaching strategy could potentially promote deeper learning of course content
