The Effect of Job Satisfaction on the Organisational Commitment of Administrators

Administrators are an important human resource in Higher Education because they perform various duties that are critical to the daily operations of universities. In light of this, organisational commitment and job satisfaction of administrators are essential for the efficiency and effectiveness of universities. Notwithstanding the critical relevance and necessity of organisational commitment and job satisfaction, there is evidence of paucity of research on these areas among administrative staff in the South African higher education sector. The objective of this study was to examine the relationship between organisational commitment and overall job satisfaction on the organisational commitment of administrators at a university in Gauteng. To achieve the aforementioned objective, a quantitative survey approach was used to examine the relationship between overall job satisfaction and organisational commitment. The selfadministered structured questionnaires were issued to 383 administrative staff members. Descriptive statistics was utilised to assess the levels of both organisational commitment and job satisfaction, results of which revealed that administrators were satisfied with and committed to the university. Spearman’s rho correlation analysis showed that there was a strong correlation between affective commitment and job satisfaction; and moderate correlations between job satisfaction and moral imperative. Similar strong correlation was observed between indebted obligation and job satisfaction. Conversely, a weak correlation occurred between job satisfaction and continuance commitment. Regression coefficients indicated that job satisfaction contributed positively to the prediction of affective commitment, moral imperative, indebted obligation and continuance commitment. Based on these findings, the recommendations and future research opportunities were suggested

Assessing the transparency of informed consent in feasibility and pilot studies: a single-centre quality assurance study protocol

Introduction Pilot/feasibility studies assess the feasibility of conducting a larger study. Although researchers ought to communicate the feasibility objectives to their participants, many research ethics guidelines do not comment on how informed consent applies to pilot studies. It is unclear whether researchers and research ethics boards clearly communicate the purpose of pilot studies to participants consenting. The primary objective of this study is to assess whether pilot/feasibility studies submitted for ethics approval to a research ethics board transparently communicate the purpose of the study to participants through their informed consent practice. A highly transparent consent practice entails the consent documents communicate: (1) the term ‘pilot’ or ‘feasibility’ in the title; (2) the definition of a pilot/feasibility study; (3) the primary objectives of the study are to assess feasibility; (4) the specific feasibility objectives; and (5) the criteria for the study to successfully lead to the main study. The secondary objectives are to assess whether there is a difference between submitted and revised versions of the consent documents (revisions are made to obtain research ethics approval), to determine factors associated with transparent consent practices and to assess the consistency with which pilot and feasibility studies assess feasibility outcomes as their primary objectives. Methods and analysis This is a retrospective review of informed consent information for pilot/feasibility studies submitted to the Hamilton integrated Research Ethics Board, Canada. We will look at submitted and revised consent documents for pilot/feasibility studies submitted over a 14-year period. We will use descriptive statistics to summarise data, reporting results as percentages with 95% CIs, and conduct logistic regression to determine characteristics associated with transparent consent practices. Ethics and dissemination The study protocol was approved by the Hamilton integrated Research Ethics Board, and the results of this study will be submitted for publication in a peer-reviewed journal

A critical analysis of Discovery Health’s claims-based risk adjustment of mortality rates in South African private sector hospitals

In 2019, Discovery Health published a risk adjustment model to determine standardised mortality rates across South African private hospital systems, with the aim of contributing towards quality improvement in the private healthcare sector. However, the model suffers from limitations due to its design and its reliance on administrative data. The publication’s aim of facilitating transparency is unfortunately undermined by shortcomings in reporting. When designing a risk prediction model, patient-proximate variables with a sound theoretical or proven association with the outcome of interest should be used. The addition of key condition-specific clinical data points at the time of hospital admission will dramatically improve model performance. Performance could be further improved by using summary risk prediction scores such as the EUROSCORE II for coronary artery bypass graft surgery or the GRACE risk score for acute coronary syndrome. In general, model reporting should conform to published reporting standards, and attempts should be made to test model validity by using sensitivity analyses. In particular, the limitations of machine learning prediction models should be understood, and these models should be appropriately developed, evaluated and reported.http://www.samj.org.zaam2023Gordon Institute of Business Science (GIBS

Tri-ponderal mass index in survivors of childhood brain tumors: A cross-sectional study.

Survivors of childhood brain tumors (SCBT) face a higher risk of cardiometabolic disorders and premature mortality compared to the general population. Excess adiposity is a known risk factor for these comorbidities. However, while SCBT have higher adiposity compared to healthy controls, measuring adiposity in clinical practice involves access to specialized equipment and may impact busy clinical services. Tri-ponderal Mass Index (TMI; kg/

Transmission of respiratory viruses when using public ground transport : a rapid review to inform public health recommendations during the COVID-19 pandemic

CITATION: Zhen, J. et al. 2020. Transmission of respiratory viruses when using public ground transport : a rapid review to inform public health recommendations during the COVID-19 pandemic. South African Medical Journal, 110(6), doi:10.7196/SAMJ.2020.v110i6.14751.The original publication is available at http://www.samj.org.zaIn response to the COVID-19 pandemic, numerous countries worldwide declared national states of emergency and implemented interventions to minimise the risk of transmission among the public. Evidence was needed to inform strategies for limiting COVID-19 transmission on public transport. On 20 March 2020, we searched MEDLINE, CENTRAL, Web of Science and the World Health Organization’s database of ‘Global research on coronavirus disease (COVID-19)’ to conduct a rapid review on interventions that reduce viral transmission on public ground transport. After screening 74 records, we identified 4 eligible studies. These studies suggest an increased risk of viral transmission with public transportation use that may be reduced with improved ventilation. International and national guidelines suggest the following strategies: keep the public informed, stay at home when sick, and minimise public transport use. Where use is unavoidable, environmental control, respiratory etiquette and hand hygiene are recommended, while a risk-based approach needs to guide the use of non-medical masks.http://www.samj.org.za/index.php/samj/article/view/12943Publisher's versio

High molecular weight adiponectin levels are inversely associated with adiposity in pediatric brain tumor survivors.

While children with brain tumors are surviving at record rates, survivors are at risk of cardiovascular disease and type 2 diabetes mellitus; these conditions may be driven by excess body fat. Adiponectin in an adipokine that is inversely associated with the fat mass, and has been linked to cardiometabolic risk stratification in the general population. However, adiponectin\u27s profile and determinants in SCBT have not been established. We tested the hypothesis that high molecular weight (HMW) adiponectin levels, the more biologically active form of adiponectin, were associated with adiposity in SCBT similarly to non-cancer controls. Seventy-four SCBT (n = 32 female) and 126 controls (n = 59 female) who were 5-17 years old were included. Partial correlations and multivariable regression analyses assessed the relationship between HMW adiponectin and adiposity. HMW adiponectin was inversely associated with total and central adiposity (FM%: β - 0.21, 95% CI - 0.15, - 0.08; p value \u3c 0.0001; WHR: β - 0.14, 95% CI - 0.02, - 0.01; p value \u3c 0.0001 ;WHtR: β - 0.21, 95% CI - 0.05, - 0.03; p value \u3c 0.0001). In conclusion, HMW adiponectin is inversely correlated with adiposity in SCBT. Adiponectin may serve as a biomarker of cardiometabolic risk and response to interventions to prevent and manage obesity and its comorbidities in SCBT
