    A balanced treatment of perceived organizational politics: A review of the positive influences
    (Human Resources Management and Services, 2024-02-22) Nyathi, M.
    Purpose: The purpose of this paper is to review literature in the area of perceived organizational politics (POPs) and to present a model that explains the positive role of the phenomenon in the workplace. This involves understanding how POPs have evolved from playing a much-publicized destructive role to an emerging constructive one. Design/methodology/approach: An integrative review method was used to review articles on POPs published over the last 13 years (2010–2022). The primary sources of information were several databases, such as ISI Web of Science, Google Scholar, and Scopus. Specific search terms were considered to find relevant articles, leading to 7803 articles (3894 hits on Scopus, 1723 hits on Google Scholar, and 2186 hits on Web of Science). These studies were further examined for their relevance to this study, and 103 articles were identified. The application of exclusion criteria funneled them to 66 studies. The articles, employing quantitative, mixed, and qualitative approaches were coded. The themes were subsequently determined. Findings: The review notes that the POPs literature emphasis is shifting from a negative and dysfunctional approach to one where positive organizational outcomes are possible. The review concludes that POPs have functional consequences too. The phenomenon could illuminate favorable workplace outcomes if viewed as an enhancer rather than a hindrance. POPs should be viewed as a phenomenon that for all purposes is essentially neutral. It is individuals who label the otherwise neutral construct as negative (negative POPs) or positive (positive POPs). Practical implications: The paper reveals how antecedents help organizational members label politics as positive. Perceived organizational politics is largely a neutral construct until the perceiver decides to label it otherwise. A positive perception of politics is significant in predicting important employee outcomes such as motivation, employee satisfaction, and job performance. Management needs to invest in antecedents and moderators to help employees label the construct as positive rather than negative. Originality/value: The study is an original review of the positive POPs literature to identify the significant antecedents, moderators, and work outcomes, vital to organizational success.

    Background Children living with HIV requiring second-line antiretroviral therapy (ART) have limited options, an unmet need considering children require life-long ART. Methods Children from Uganda, Zambia, Zimbabwe were randomised to one of four second-line anchor drugs: dolutegravir(DTG), ritonavir-boosted darunavir(DRV/r), atazanavir(ATV/r), or lopinavir(LPV/r) in the factorial CHAPAS-4 trial (second randomisation to tenofovir alafenamide fumarate(TAF) or standard-of-care(SOC) backbone, reported elsewhere). Dosing followed WHO weight-bands. The primary endpoint was viral load(VL) <400copies/mL at week-96, analysed using logistic regression, hypothesising that DTG and DRV/r would be superior (threshold p=0.03) to LPV/r and ATV/r arms combined and ATV/r would be non-inferior to LPV/r(12% margin). Secondary endpoints included immunology and safety. Analyses were intention-to-treat. Results 919 children, median(IQR) age 10(8-13) years, 54% male, baseline VL 17,573(5549,55700) copies/mL, CD4 669(413, 971) cells/mm, weight-for-age Z-score -1.6(-2.4,-0.9), had spent median(IQR) 5.6(3.3,7.8) years on first-line ART. At week-96, DTG was superior (by 9.7%(95% CI 4.8%, 14.5%); p<0.0001) and DRV/r showed a trend to superiority(by 5.6%(0.3%, 11.0%); p=0.04) compared to LPV/r and ATV/r arms combined. ATV/r was non-inferior to LPV/r(+3.4%(-3.4%,+10.2%); p=0.33). CD4 counts increased with no differences between arms. Toxicity was lowest with DTG. All arms except LPV/r showed age-appropriate weight/height gains at week-96. DTG was not associated with excess absolute weight-gain(<1kg) vs. DRV/r or ATZ/r, irrespective of backbone randomisation. Conclusions DTG-based regimens are safe and cost-effective for second-line ART. DRV/r and ATV/r are also good options. Fixed-dose combinations of DTG, DRV/r or ATV/r with nucleoside/nucleotide-reverse-transcriptase-inhibitors(NRTIs) would increase access to robust, essential second-line options for children.(ISRCTN22964075)

    Evaluating the effectiveness of blended learning in learning business courses in lowincome economies
    (Emarald Insight, 2024-05-10) Nyathi, M.
    Purpose This paper evaluated the effectiveness of blended learning of business courses in higher learning institutions (HEIs) in developing economies. Design/methodology/approach A survey, involving 215 learners, was used to collect data. A stratified sampling technique was used in this study. The data were analyzed using the PROCESS macro in SPSS. Findings In the blended learning approach, student attitudes, social presence, IT infrastructure and flexible learning are all favorable predictors of learner satisfaction. The impact of blended learning on learner satisfaction is further mediated by IT infrastructure, social presence and learner attitude. Practical implications HEIs need to invest in planning and resource mobilization in order to realize several benefits derived from the use of blended learning. For optimal learning outcomes, this should be combined with training on IT infrastructure usage for both facilitators and learners. In order to assist learners in developing competencies through consistent use, institutions should also invest in tailored blended learning technologies. In addition, emphasis should be placed on training all actors in order to better manage change. Originality/value This paper presents and ranks several dimensions for blended learning success in low-budget universities. In addition, the study contributes to the understanding of intervening variables necessary for enhancing the potential of pedagogy in maximizing learner satisfaction.
