Psychological career meta-capacities in relation to employees’ retention-related dispositions

Staff retention has become a complex issue facing many contemporary organisations. The study examined the relationship dynamics between employees’ psychological career meta-capacities (measured by the Psychological Career Resources Inventory) and their retention-related dispositions (measured by the Utrecht Work Engagement Scale and the Organisation-related Commitment Scale). A quantitative survey was conducted involving a non-probability purposive sample of predominantly black females in the early life career stage, employed at managerial and staff levels (N = 318) in the field of industrial and organisational psychology. A canonical correlation analysis indicated a significant overall relationship between the psychological career meta-capacities and the retention- related dispositions. Structural equation modelling indicated a good fit of the data with the canonical correlation-derived measurement model. In the employment equity context, the findings provide valuable pointers for the design of career development practices aimed at retaining black females in the early career stage of their lives.Key words: career development, retention, psychological career resources, career meta-capacities, career foci, commitment foci, work engagemen

Concept mapping as a strategy to scaffold concept literacy in accounting for extended programmes

While great strides have been made to improve accessibility to higher education in South Africa, successful completion of bachelor's degrees within the prescribed time remains a challenge.  Research suggests that a lack of conceptual understanding by students might be at the heart of the problem. This study, which is grounded in Ausubel's Assimilation Theory as applied by Joseph Novak and his colleagues, investigates the value of concept mapping as a scaffolding technique to improve conceptual understanding. The research involved a quasi-experiment with a test and a control group. It was hypothesised that accounting students in an extended programme who had been introduced to the concept mapping technique would demonstrate an improved grasp of accounting concepts, indicated by an improvement in their marks when composing an explanatory paragraph of accounting concepts after a teaching intervention. However, the post-intervention marks of the test group showed no improvement, and therefore no proof can be offered to support the claim that concept mapping improves conceptual understanding. Pre-and post-intervention questionnaires were used to collect data on confounding variables and also to assess student experiences of concept mapping. An analysis of student experiences indicated enthusiasm for the technique. Limitations of the study included the absence of a pilot study and insufficient time to become familiar with concept mapping. An unforeseen constraint on the study was low student participation

Prevalence of free-living acanthamoeba and its associated bacteria in energy-efficient hot water systems in South Africa

As part of the Eskom rebate programme, energy-efficient hot water systems such as solar water heaters (low pressure), heat pumps and energy-efficient showerheads were rolled out to the public as a measure to conserve and save energy. There has been a concern that these systems may not reach the required high temperatures, especially during winter, and, as a result of this, Acanthamoeba and its associated bacteria such as Legionella pneumophila, Pseudomonas aeruginosa and nontuberculous mycobacteria could flourish within these systems causing a potential health risk to consumers. This study examined the relationship between Acanthamoeba and its associated bacteria at different temperature ranges. A total of 156 water (69) and biofilm samples (87) were collected from a solar water heater, heat pump, geyser and showerheads and examined for these organisms using amoebal enrichment and molecular techniques. Amoeba could be cultivated from 45 (65.2%) of the water samples and 56 (64.4%) of the biofilm samples. The study confirmed the presence of Legionella pneumophila, Pseudomonas aeruginosa and nontuberculous mycobacteria in the hot water systems at both of the simulated winter (20°C to 30°C) and higher summer (40°C to 55°C) temperatures as well as the control system. There was a significant positive correlation between the presence of Acanthamoeba and the presence of Pseudomonas. Based on this association it is suggested that Pseudomonas aeruginosa could be investigated as an indicator organism for the presence of Acanthamoeba and opportunistic pathogens

Independent and combined effects of improved water, sanitation, and hygiene, and improved complementary feeding, on child stunting and anaemia in rural Zimbabwe: a cluster-randomised trial.

BACKGROUND: Child stunting reduces survival and impairs neurodevelopment. We tested the independent and combined effects of improved water, sanitation, and hygiene (WASH), and improved infant and young child feeding (IYCF) on stunting and anaemia in in Zimbabwe. METHODS: We did a cluster-randomised, community-based, 2 × 2 factorial trial in two rural districts in Zimbabwe. Clusters were defined as the catchment area of between one and four village health workers employed by the Zimbabwe Ministry of Health and Child Care. Women were eligible for inclusion if they permanently lived in clusters and were confirmed pregnant. Clusters were randomly assigned (1:1:1:1) to standard of care (52 clusters), IYCF (20 g of a small-quantity lipid-based nutrient supplement per day from age 6 to 18 months plus complementary feeding counselling; 53 clusters), WASH (construction of a ventilated improved pit latrine, provision of two handwashing stations, liquid soap, chlorine, and play space plus hygiene counselling; 53 clusters), or IYCF plus WASH (53 clusters). A constrained randomisation technique was used to achieve balance across the groups for 14 variables related to geography, demography, water access, and community-level sanitation coverage. Masking of participants and fieldworkers was not possible. The primary outcomes were infant length-for-age Z score and haemoglobin concentrations at 18 months of age among children born to mothers who were HIV negative during pregnancy. These outcomes were analysed in the intention-to-treat population. We estimated the effects of the interventions by comparing the two IYCF groups with the two non-IYCF groups and the two WASH groups with the two non-WASH groups, except for outcomes that had an important statistical interaction between the interventions. This trial is registered with ClinicalTrials.gov, number NCT01824940. FINDINGS: Between Nov 22, 2012, and March 27, 2015, 5280 pregnant women were enrolled from 211 clusters. 3686 children born to HIV-negative mothers were assessed at age 18 months (884 in the standard of care group from 52 clusters, 893 in the IYCF group from 53 clusters, 918 in the WASH group from 53 clusters, and 991 in the IYCF plus WASH group from 51 clusters). In the IYCF intervention groups, the mean length-for-age Z score was 0·16 (95% CI 0·08-0·23) higher and the mean haemoglobin concentration was 2·03 g/L (1·28-2·79) higher than those in the non-IYCF intervention groups. The IYCF intervention reduced the number of stunted children from 620 (35%) of 1792 to 514 (27%) of 1879, and the number of children with anaemia from 245 (13·9%) of 1759 to 193 (10·5%) of 1845. The WASH intervention had no effect on either primary outcome. Neither intervention reduced the prevalence of diarrhoea at 12 or 18 months. No trial-related serious adverse events, and only three trial-related adverse events, were reported. INTERPRETATION: Household-level elementary WASH interventions implemented in rural areas in low-income countries are unlikely to reduce stunting or anaemia and might not reduce diarrhoea. Implementation of these WASH interventions in combination with IYCF interventions is unlikely to reduce stunting or anaemia more than implementation of IYCF alone.

Extending the measurement of quality beyond service delivery indicators.

Assessing the quality of healthcare services is a priority in low-resource and high-resource settings alike. It is, however, a complex endeavour. Outcome measures are subject to case-mix variation, often require lengthy follow-up periods to manifest, and are generally costly to monitor. Therefore, structure and process measures are routinely considered reliable alternatives under the assumption of a causal link between the provision of care and improved health status. In this edition of BMJ Global Health, Giorgio et al used such structure and process measures—that is, service delivery indicators (SDI)—to assess the quality of healthcare across 10 African countries.2 The SDI programme was set up to conduct crosssectional nationally representative surveys that examine service delivery performance in education and health in Africa. The health indicators assess health worker availability, health worker knowledge on the management of common ailments, and availability of selected essential equipment and treatments. These surveys are aimed at providing high-level snapshots of the quality of health services in target countries. In this editorial, we discuss some of the limits of using data from a platform such as the SDI programme to make sense of quality of care and highlight complementary approaches that are aligned with emergent thinking in the field

Establishing the safety of the lateral femoral cutaneous nerve when using the Bridging Infix for anterior pelvic fixation

Objectives: Established subcutaneous internal fixation techniques have shown a better quality of life with reduced pain. However, complications still arise with the most significant being injury of the lateral femoral cutaneous nerve (LFCN). A novel minimally invasive modified technique, the Bridging Infix, has been proposed, however the safety of the LFCN during the procedure is currently unknown. Therefore, the aim of the study was to determine the relationship between the Bridging Infix and the LFCN. Patients and methods: Fifty formalin-fixed cadaveric specimens and two fresh frozen cadaver specimens were utilized in the study. The Bridging Infix was inserted as per the technique guide. Superficial dissection of the surgical site was subsequently conducted. Bilateral measurements of the distance between the LFCN and the implant as well as palpable bony landmarks were taken to determine safe zones for implant placement. Results: Overall the LFCN was identified coursing deep to the inguinal ligament. The minimum distance from the LFCN to the most proximal cortical screw was 18.00 mm. The mean distance from the most proximal screw to the LFCN was 37.97 ± 12.20 mm. Conclusion: The LFCN was not injured or impinged by the Bridging Infix in any of the cadaver specimens used in this study. Thus, the surgical procedure can be considered safe if layer by layer dissection is employed and the screws are directly inserted on the iliac crest, with no pressure being applied within three finger breadths medial to the anterior superior iliac spine (ASIS)

Pediatricians as Childhood Development Advocacy Champions in Kenya and Tanzania: A case study

Early childhood development (ECD) is instrumental to shaping educational, emotional, and economic trajectories; alleviating poverty; and achieving gender equality. Pediatricians are experts in children\u27s health and trusted sources of guidance for families and clinicians and thus are optimal ECD champions. This case study describes collaboration by the American Academy of Pediatrics, Kenya Pediatric Association, and Pediatric Association of Tanzania to activate pediatricians as ECD champions in Kenya and Tanzania. From July 2020 through January 2021, the collaborators assessed ECD needs by interviewing 20 key informants per country from governmental ministries, nongovernmental organizations, and clinical practice and assessing datasets and policy documents. In 2021, the societies recruited 15 pediatricians per country as champions; surveyed their knowledge, attitudes, and practices; and trained them on 4 core competencies: understanding early brain development science; developmental and behavioral screening, surveillance, and diagnosis; integration of ECD promotion into clinical practice; and advocacy skills for ECD and nurturing care. In 2021, each society established advocacy-in-action projects to advance ECD. In Kenya, the cohort surveyed clinicians on barriers to ECD, implemented a 2-day in-person training for 90 providers, and developed a 5-week Fundamentals of ECD course, taken by 113 pediatricians from 7 African countries. In Tanzania, champions conducted ECD training workshops for 78 health managers and 189 health care providers in 9 facilities in 7 regions and established 9 ECD corners with toys and information in health care facilities. These results highlight considerations for supporting ECD, including building on existing strengths, infrastructure, and networks; strengthening ECD knowledge among pediatricians; and advocacy skill-building
