- ItemAdverse events of iron and/ or erythropoiesis-stimulating agent therapy in preoperatively anemic elective surgery patients: a systematic review(BioMed Central Ltd, 2022-10-27) Laermans, Jorien; Van Remoortel, Hans; Avau, Bert; Bekkering, Geertruida; Georgsen, Jorgen; Manzini, Paola Maria; Meybohm, Patrick; Ozier, Yves; De Buck, Emmy; Compernolle, Veerle; Vandekerckhove, PhilippeBackground Iron supplementation and erythropoiesis-stimulating agent (ESA) administration represent the hallmark therapies in preoperative anemia treatment, as reflected in a set of evidence-based treatment recommendations made during the 2018 International Consensus Conference on Patient Blood Management. However, little is known about the safety of these therapies. This systematic review investigated the occurrence of adverse events (AEs) during or after treatment with iron and/or ESAs.
- ItemAdvocacy, activism, and lobbying: How variations in interpretation affects ability for academia to engage with public policy(PLOS, 2022-03-18) Jessani, Nasreen S.; Ling, Brenton; Babcock, Carly; Valmeekanathan, Akshara; Holtgrave, David R.Research and teaching are considered core-responsibilities for academic researchers. “Practice” activities however are viewed as ancillary, despite university emphasis on their importance. As funders, governments, and academia address the role of research in social impact, the deliberations on researcher activism, advocacy and lobbying have seen a resurgence. This study explores the perceptions of 52 faculty and 24 government decisionmakers on the roles, responsibilities, and restrictions of an academic to proactively engage in efforts that can be interpreted under these three terms. Data was coded through inductive thematic analysis using Atlas.Ti and a framework approach. We found that discordant perceptions about how much activism, advocacy and lobbying faculty should be engaging in, results from how each term is defined, interpreted, supported and reported by the individuals, the School of Public Health (SPH), and government agencies. Influential faculty factors included: seniority, previous experiences, position within the institution, and being embedded in a research center with an advocacy focus. Faculty views on support for advocacy were often divergent. We surmise therefore, that for effective and mutually beneficial collaboration to occur, academic institutions need to align rhetoric with reality with respect to encouraging modes and support for government engagement. Similarly, government agencies need to provide more flexible modes of engagement. This will contribute to alleviating confusion as well as tension leading to more effective engagement and consequently opportunity for evidence-informed decision making in public health globally.
- Item'n Bedryfsielkundige ondersoek na die bruikbaarheid van die Myers-Briggs Type Indicator as spanontwikkelingsinstrument(Stellenbosch : Stellenbosch University, 1993) Verster, L. G.; Calitz, C. J.; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Industrial Psychology.It used to be that an entrepreneur could build a company on his own. Those days are gone. Today's business environment is so complex and in such a continual state of change that success often depends on the outputs of teams or work groups rather than the efforts of a single person. The necessity for people to work in teams, has led to the development of team development and team building strategies. An instrument often used in this capacity is the Myers-Briggs Type Indicator (MBTI). This psychological instrument is based on Carl Jung's theory of personality types and reports preferences and styles of interaction. Many authors describe the use of the MBTI as a team development instrument, but there seems to be a lack of supportive empirical evidence. This study attempts to investigate the use of the MBTI as a team development instrument to enhance the climate and effectiveness of a team. Teams working in a public service sector, and management teams of different companies took part in MBTI team development sessions. The hypothesis stating that there would be a significant difference in the climate and effectiveness of teams after MBTI team development, were investigated. With the teams in the public sector an effort was made to measure the climate and effectiveness of three experimental groups and a control group before and after the experimental treatment. The same procedure was planned for the management teams. The data of the control group of the teams in the public service sector could not be obtained at the second measurement. The analysis of the data of the experimental teams indicated no significant support for the hypothesis. With further analysis a significant correlation between team climate and team effectiveness was found. The composition of personality types in the teams and the implications thereof are discussed. It came to light that the management teams were not actual work teams, therefore the second measurement was not carried out with these groups. The composition of types within these teams were analysed, discussed and compared to similar research. A number of conclusions and suggestions for further research are made.
- ItemThe budgetary and welfare consequences of security co-operation in the southern hemisphere : a South African perspective(Stellenbosch University, Military Science, 1997) Roux, AndreThe end of the Cold War, new global circumstances, and the democratisation process in South Africa have resulted in a transformation of the way in which defence matters in this country are evaluated and approached. From 1960 to the end of the 1980s defence spending decisions in South Africa were largely influenced by non-economic considerations, such as the perceived need to protect national values from foreign aggression and internal threats to stability, the ideological inclination of the government of the day, and a sense of inertia and incrementalism in respect of defence budgets. However, since 1989 the greater unlikelihood of an imminent foreign act of conventional aggression against the country and the advent of multi-party democracy, have served to highlight the possible trade-off between defence and socio-economic welfare (the so-called 'guns versus butter' debate). Indeed, since the end of the 1980s real defence expenditure in South Africa has declined by almost 60 percent, while the defence burden (defence expenditure as a percentage of gross domestic product) has fallen to below 2,0 percent.
- ItemConverting tacit knowledge into explicit knowledge in organisations : a communication challenge(School of Communication, UJ, 2002) Hugo-Burrows, M. M.Business organisations are increasingly viewing knowledge as their most valuable and strategic resource to remain competitive. Every organisation has both explicit knowledge, referring to carefully analysed and defined knowledge, and tacit knowledge, referring to complex knowledge, difficult to specify and often unrecorded. Tacit knowledge becomes embedded in an individual's personal expertise and cannot be expressed through the normal use of words. But it is precisely the tacit knowledge that often delivers a sustainable competitive advantage, as it is this part that competitors have difficulty in replicating. Many organisations are realizing that they must explicitly manage their knowledge resources and capabilities, and they have initiated a range of knowledge management programmes. An important managerial responsibility resides in managing the knowledge transfer context, including the assessment of all knowledge possessed by a firm. This necessitates the conversion of tacit knowledge into explicit knowledge. This article looks at the tacit knowledge literature and focuses on the existing methods of converting tacit knowledge into implicit knowledge in organisations. A pilot survey on existing tacit knowledge articulation in a large South African province is discussed. This has pointed towards a more comprehensive research project, with the aim of providing a model for tacit knowledge communication strategies in South African multicultural firms.

- ItemDecolonial gestures of heutagogy : a postqualitative inquiry into the potential of self-determined learning in Stellenbosch University’s postgraduate diploma in sustainable development(Stellenbosch : Stellenbosch University, 2023-03) Dalamakis, Guy Michael Melless; Davies, Megan Lynne; Stellenbosch University. Faculty of Economic and Management Sciences. Centre for Sustainability Transition.ENGLISH SUMMARY: The ideologies governing our socio-economic systems have resulted in a multitude of ‘wicked’ problems – sustainability challenges riddled with unceasing complexity, debate, and uncertainty as to how best respond to these ordeals. While we may have reached a general comprehension regarding the nature of these complexities, we are yet to realise the means of appropriately responding to them. Amidst this uncertainty, numerous global reports have agreed on at least one crucial requirement for aptly responding to the multifarious challenges with which we are faced: a comprehensive reimagining of education and the ways in which we learn as a society. With this, sustainability education has emerged as a means of providing learning experiences that seek to support the systemic change required to address the social-ecological challenges with which we are faced. That said, educational reforms are often underpinned by colonial frames of reference and thus further socio-economic rationalities and consequently perpetuate a world in crisis. Therefore, there exists a certain tension in the realm of higher education whereby, on one hand, it can be utilised as a means of preserving unsustainable engagements with the world while, on the other, it holds the very means of providing learning experiences that more adequately respond to our systemic crises. Thus far, sustainability education has been largely underpinned by the assumption that all offerings are sufficient in and of themselves in that a transformative learning experience is guaranteed due to the inclusion of sustainability content. In other words, there has been a predominant focus on curriculum while pedagogy falls by the wayside. Forming the very foundation of educational experiences, informing pedagogies will require greater consideration if sustainability education seeks to deliver that which it has set out to achieve. Pedagogical approaches to sustainability education thus need to be reoriented accordingly so as to imbue students with a change agency and response-ability that enables them to both transform and transgress the established systems in which they find themselves embedded. Therefore, through the espousal of a postqualitative inquiry, this thesis explores the nascent potential of heutagogy—a learner-centred approach to education—in fostering these necessary shifts. Contextualised within an academic programme in a higher education institution in South Africa, this research inquires into the extent to which heutagogy is an embedded quality within the Postgraduate Diploma in Sustainable Development at Stellenbosch University and the role this might play in contributing toward transformative and transgressive spaces of teaching and learning.
- ItemA demographic profile of the Cape Metropolitan Area, 1996 and 2021(Faculty of the Humanities, University of the Free State, 2001) Haldenwang, BarbelWith a total population of 2.56 million in 1996, the Cape Metropolitan Area (CMA) is the third largest metropole in South Africa. It is the second largest contributor to the country’s GDP, accounts for 8.0% of employment, and is a popular migration destination, especially from the Eastern Cape. The population of the CMA is demographically young, with more females than males, and it is dominated by the coloured population group. Each of the six local authority areas has its own unique demographic profile. By 2021, between 0.76 million and 1.56 million additional people could be residing in the CMA, with Tygerberg and Central Cape Town expected to experience the highest population growth rates.

- ItemDevelopment of a questionnaire for assessing work unit performance(AOSIS, 2004-10) Spangenberg, H. H.; Theron, C.The aim of this study was to develop a generic work unit performance measure that can be utilized in private, public and non-profit work units. Development of such a questionnaire, called the Performance Index (PI) comprised three steps, namely deciding on a baseline structure for the model; verifying the model and dimensions through subject expert feedback; and consolidating the model and refining the questionnaire. The sample consisted of 60 units rated on a 360 basis by 257 respondents. Item and dimensionality analyses, followed by confirmatory factor analysis utilizing LISREL produced acceptable model fit. Overall, results provided reasonable psychometric support for the Performance Index.

- ItemAn early career in the military : a developmental-contextual perspective(AOSIS, 1999) Kotze, M. E.; Duvenhage, A.Young professional military officers' experience of their internal career development was studied longitudinally from a life-span, life-space approach. Significant transitions between the life roles of worker, student and leisurite, with concomitant changes in their value system, away from traditional military values towards occupationalism, were confirmed. Gender differences were found for the work and community roles as well as in the developmental patterns of the need for authority, creativity, cultural identity, physical activities, social relationships and variety. Significant differences between the career development profiles of military and civilian students with regard to life roles were revealed.
- ItemEffects of cannabidiol on vacuous chewing movements, plasma glucose and oxidative stress indices in rats administered high dose risperidone(Springer Nature, 2022-11-16) Kajero, Jaiyeola Abiola; Seedat, Soraya, 1966-; Ohaeri, Jude; Akindele, Abidemi; Aina, OluwagbemigaAtypical antipsychotics, despite their rapid dissociation from dopamine receptors and reduced tendency to induce oxidative stress, have been associated with difficult-to-manage movement disorders, including tardive dyskinesia (TD). The study set out to investigate the effects of cannabidiol (CBD), a potent antioxidant, on risperidone-induced behavioural and motor disturbances; namely vacuous chewing movements (VCM), and oxidative stress markers (e.g. superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH), malondialdehyde (MDA), Nitric oxide (NO), and DPPH (2,2-diphenyl-1-picrylhydrazyl)). Oral risperidone (10 mg/kg) or oral CBD (5 mg/kg) were administered to six experimental groups. While risperidone alone was administered for 28 days, CBD concomitantly or in sequential order with risperidone, was administered for 28 days; and CBD alone was administered for 21 days. Behavioural, motor, and specific biochemical parameters, which included VCM, muscle tone, fasting blood sugar (FBS), and oxidative stress markers were assessed at different time points after the last dose of medication. Oral CBD (5 mg/kg) significantly reduced risperidone-induced elevated FBS when given after the administration of risperidone. Oral CBD also had effects on VCM when administered before risperidone and similarly, attenuated risperidone-induced increased muscle tone. It was also established that concomitant or sequential administration of CBD and risperidone did not have any adverse effects on cognition or locomotion. Both CBD and risperidone increased the activity of antioxidant enzymes and decreased the activity of pro-oxidant enzymes. This study suggests CBD could mitigate metabolic dysregulation and extrapyramidal side effects associated with risperidone without producing cognitive impairments.
- ItemEffects of damping constant of electron and size on quantum-based frequency-dependent dielectric function of small metallic plasmonic devices(Elsevier B.V, 2022-07) Akinyemi, Lateef; Oladejo, Sunday; Ekwe, Stephen; Imoize, Agbotiname Lucky; Ojo, Stephen AbiodunElectron surface dissipation and quantum-limited size tend to control the material properties of exterior plasmon oscillation as the size of metal nanoparticles goes into the nanoscale domain. The need to examine this characteristic behaviour and its potential becomes imperative. This study explores the effects of the damping constant of electrons and size quantum-based frequency-dependent dielectric function (FDDF) of small metallic materials using an elementary model of electrons in a confined box. The frequency-dependent dielectric function is employed to study quantum size impacts and damping constant in the optical spectra region. The quantum amended frequency-dependent dielectric function and the absorbing spectra of silver-cube geometry for different sizes by adding damping constant and without damping constant are critically examined. The findings reveal that when the damping constant effect is absent, the multiple crests emerge for the quantum-amended frequency-dependent dielectric function and absorbing spectra of the metallic materials, highlighting the electronic discretization levels in the tiny quantum-limited structure. While the damping constant is included, the multiple summits are hidden and vanish owing to a considerable widening of the structures independently. The change in the numerical results from the quantum case to the classical case for growing widths is further illustrated for both cases. The numerical results enhance our knowledge of damping constant dissipation and quantum limited-size impact in small-scaled plasmonic devices.
