The Effect of Black Tax on Employee Engagement: The Mediating Role of Idiocentrism-Allocentrism-A Case of Pharmaceutical Industry in Zimbabwe
Employees in the Pharmaceutical industry are coming late to work and knocking off early. These actions unveiled by the employees are likely to incur economic costs on the employer, occasioned by low employee productivity. Owners of production have expressed concern over the general low staff morale in the pharmaceutical sector. While most studies have concentrated on internal job-related factors as drivers of employee engagement, this study seeks to assess employee engagement as being influenced by black tax, an external factor. The main aim of the research was to establish the influence of black tax on employee engagement, being mediated by idiocentrism-allocentrism, particularly focussing on the pharmaceutical manufacturing and retailing industry in Bulawayo, Zimbabwe. The study employed the philosophical approach of pragmatism to guide the whole research. The researcher adopted a multi-stage sampling technique supported by the census technique to pick participants from the population. Closed and open-ended questionnaires were used to collect data from qualified pharmacists who are working in both the manufacturing and retailing industry in Bulawayo. Statistical Package for Social Sciences v23 (Process v3.5 by Andrew F. Hayes) was used to test the hypothesized relationship among variables. Qualitative data were analyzed using thematic analysis. The results suggest that black tax directly influence employee engagement in the presence of a mediator (idiocentrism-allocentrism). Furthermore, the results indicate that the indirect coefficient was partially significant, which means that idiocentrism-allocentrism has a partial influence on employee engagement. The researchers recommend that management should ensure that employees are motivated all the time. They should implement an open-door policy so that employees can share their issues that affect their engagement level at work
CHINESE’S MESSIAH OR MONSTER ACTIVITIES ON ECONOMIC GROWTH IN SOUTHERN AFRICA?
Industrialization of the Chinese economy has made China a formidable force in the global economy. Similarly, Africa has witnessed increased Chinese activity as shown by rising figures in trade with China, Chinese foreign direct investments, Chinese aid and debt to Africa. Despite the rise in Chinese activities in Africa, there is doubt about the impact of such on growth of African economies. Chinese aid and debt are observed to bear hidden costs that outweigh the benefits. Whereas Chinese trade and investments are claimed to be resource seeking and not genuine. The World Bank also observed that Chinese finance is secretive and does not comply with the best practices of good governance. In this regard, this paper aims to assess the impact of Chinese activities in Southern Africa. The paper uses an explanatory research design. On determining the effect of Chinese activities, we adapt a Solow-growth model. A panel data set is assembled using individual countries’ time series data on the variables of interest. The study uses real GDP growth rate as the dependent variable. The explanatory variables in this paper are GDP per capita, trade with the rest of the world, rest of the world foreign direct investment, Chinese trade, Chinese debt, Chinese FDI, Chinese aid and population growth. Document analysis is the major data collection tool in this paper. Data on Chinese debt, investments, trade and aid is on documents of the Ministry of Commerce of China and John Hopkins University China Africa Research Initiative. Whereas, data on world trade, FDI inflows, population growth, real GDP growth and GDP per capita is on World Bank and IMF public data sets. We use Stata 15 for data analysis. The diagnostic tests showed that we have a problem of heteroscedasticity and auto-correlation. Whereas, the Hausman model choice test showed that the random effects model is the most efficient and consistent than the fixed effects model. We therefore adopt the Feasible Generalised Least Squares regression (FGLS); as this model is robust under autocorrelation and heteroscedasticity. The regression results show that GDP per capita and rest of the word FDI are the only statistically significant explanatory variables at 5% level of significance. All the other variables that is Chinese trade, Chinese debt, Chinese FDI, Chinese aid, population growth and trade with the rest of the world became statistically significant at 10% level. The study recommends that Southern African countries need to establish a thriving democracy and improve the quality of institutions as a way to attract long term investments from the rest of the world. On dealing with China, the paper observes that there is a possibility that all citizens can benefit from Chinese activities and as a region there is need to change the current systems that benefit the political elite and support corruption at the expense of sustainable and inclusive economic development
Perceptions of 4-H Extension Educators and Volunteer Leaders toward the Inclusion of Youth with Attention Deficit Hyperactive Disorder(s) in 4-H Programs
The challenges, attitudes, training and support systems needed by 4-H extension educators and volunteer leaders in order to successfully and effectively include youth with Attention Deficit Hyperactive Disorder (ADHD) in their programs are discussed within this article. Data were collected from extension educators and volunteer leaders in a Northeastern state. The results revealed that 4-H extension educators and volunteer leaders are not adequately trained to include youth with ADHD despite the fact that they may have one or two children with these symptoms in their clubs. For inclusion to be meaningful for youth with ADHD we recommend training for extension educators and volunteer leaders on characteristics of ADHD, its implication for youth involvement as well as techniques/ways of meeting the learning styles of youth with ADHD
Treg-Therapy Allows Mixed Chimerism and Transplantation Tolerance Without Cytoreductive Conditioning
Establishment of mixed chimerism through transplantation of allogeneic donor bone marrow (BM) into sufficiently conditioned recipients is an effective experimental approach for the induction of transplantation tolerance. Clinical translation, however, is impeded by the lack of feasible protocols devoid of cytoreductive conditioning (i.e. irradiation and cytotoxic drugs/mAbs). The therapeutic application of regulatory T cells (Tregs) prolongs allograft survival in experimental models, but appears insufficient to induce robust tolerance on its own. We thus investigated whether mixed chimerism and tolerance could be realized without the need for cytoreductive treatment by combining Treg therapy with BM transplantation (BMT). Polyclonal recipient Tregs were cotransplanted with a moderate dose of fully mismatched allogeneic donor BM into recipients conditioned solely with short-course costimulation blockade and rapamycin. This combination treatment led to long-term multilineage chimerism and donor-specific skin graft tolerance. Chimeras also developed humoral and in vitro tolerance. Both deletional and nondeletional mechanisms contributed to maintenance of tolerance. All tested populations of polyclonal Tregs (FoxP3-transduced Tregs, natural Tregs and TGF-β induced Tregs) were effective in this setting. Thus, Treg therapy achieves mixed chimerism and tolerance without cytoreductive recipient treatment, thereby eliminating a major toxic element impeding clinical translation of this approach
Presentations of perforated colonic pathology in patients with polymyalgia rheumatica: two case reports
<p>Abstract</p> <p>Introduction</p> <p>Polymyalgia rheumatica is an increasingly common disease in older people, which gives rise to arthralgia and is mainly treated with corticosteroids. Patients in this age group also have a higher incidence of other co-morbidities including colonic pathology. Corticosteroid usage may mask signs of sepsis or complications secondary to intra-abdominal pathology, thereby delaying diagnosis and treatment, with eventual adverse outcome. These two cases highlight the importance of awareness and prompt recognition of this condition in order to avoid significant morbidity and mortality.</p> <p>Case presentation</p> <p>Case 1</p> <p>A 73-year-old Caucasian woman with a diagnosis of polymyalgia presented with symptoms of an exacerbation in her right hip joint. Despite standard therapy with corticosteroids she failed to improve and started to develop features of widespread sepsis. Specific questioning revealed that, at the very onset of her symptoms, she had experienced mild diarrheal symptoms. Investigations revealed perforated diverticular disease with a peri-femoral abscess.</p> <p>Case 2</p> <p>A 69-year-old Caucasian woman with polymyalgia presented with left thigh pain and weakness associated with weight loss. A diagnosis of exacerbation of polymyalgia rheumatica was made and she was treated with corticosteroid therapy. Shortly afterwards she was admitted with generalized peritonitis. Laparotomy revealed a retroperitoneal abscess secondary to a perforated sigmoid colonic tumor.</p> <p>Conclusions</p> <p>Patients with polymyalgia may have perforated colonic diverticular disease which mimics their rheumatic pathology. In such cases steroid therapy, which is the mainstay of polymyalgia therapy, can be detrimental. Primary and hospital practitioners are encouraged to be vigilant regarding non-specific gastrointestinal symptoms and consider alternative diagnoses in those patients whose symptoms do not resolve with standard therapy, as this can lead to an overall better outcome.</p
Effect of secukinumab on clinical and radiographic outcomes in ankylosing spondylitis: 2-year results from the randomised phase III MEASURE 1 study.
OBJECTIVE: To evaluate the effect of secukinumab, an interleukin-17A inhibitor, on clinical signs and symptoms and radiographic changes through 2 years in patients with ankylosing spondylitis (AS). METHODS: In the phase III MEASURE 1 study, patients were randomised to receive intravenous secukinumab 10 mg/kg (at baseline, week 2 and week 4) followed by subcutaneous secukinumab 150 mg (intravenous 150 mg; n=125) or 75 mg (intravenous 75 mg; n=124) every four weeks, or matched placebo (n=122). Placebo-treated patients were re-randomised to subcutaneous secukinumab 150 or 75 mg from week 16. Clinical efficacy assessments included Assessment of SpondyloArthritis international Society 20 (ASAS20) response rates through week 104. Radiographic changes at week 104 were assessed using the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). RESULTS: 97 (77.6%) and 103 (83.1%) patients in the intravenous 150 mg and intravenous 75 mg groups, respectively, completed week 104. In the full analysis set (intent-to-treat), ASAS20 response rates at week 104 were 73.7% and 68.0% in the intravenous 150 mg and intravenous 75 mg groups, respectively. Among patients with evaluable X-rays who were originally randomised to secukinumab (n=168), mean change in mSASSS from baseline to week 104 was 0.30±2.53. Serious adverse events were reported in 12.2% and 13.4% of patients in the 150 mg and 75 mg groups, respectively. CONCLUSIONS: Secukinumab improved AS signs and symptoms through 2 years of therapy, with no unexpected safety findings. Data from this study suggest a low mean progression of spinal radiographic changes, which will need to be confirmed in longer-term controlled studies. TRIAL REGISTRATION NUMBER: NCT01358175
Characterising school-age health and function in rural Zimbabwe using the SAHARAN toolbox
INTRODUCTION:
We developed the School-Age Health, Activity, Resilience, Anthropometry and Neurocognitive (SAHARAN) toolbox to address the shortage of school-age assessment tools that combine growth, physical and cognitive function. Here we present i) development, acceptability and feasibility of the SAHARAN toolbox; ii) characteristics of a pilot cohort; and iii) associations between the domains measured in the cohort.
METHODS:
Growth was measured with anthropometry, knee-heel length and skinfold thicknesses. Bioimpedance analysis measured lean mass index and phase angle. Cognition was assessed using the mental processing index, derived from the Kaufman Assessment Battery for Children version 2, a fine motor finger-tapping task, and School Achievement Test (SAT). Physical function combined grip strength, broad jump and the 20m shuttle-run test to produce a total physical score. A caregiver questionnaire was performed in parallel.
RESULTS:
The SAHARAN toolbox was feasible to implement in rural Zimbabwe, and highly acceptable to children and caregivers following some minor modifications. Eighty children with mean (SD) age 7.6 (0.2) years had mean height-for-age (HAZ) and weight-for-age Z-scores (WAZ) of -0.63 (0.81) and -0.55 (0.85), respectively. Lean mass index and total skinfold thicknesses were related to WAZ and BMI Z-score, but not to HAZ. Total physical score was associated with unit rises in HAZ (1.29, 95% CI 0.75, 1.82, p<0.001), and lean mass index (0.50, 95% CI 0.16, 0.83, p = 0.004), but not skinfold thicknesses. The SAT was associated with unit increases in the mental processing index and child socioemotional score. The caregiver questionnaire identified high levels of adversity and food insecurity.
CONCLUSIONS:
The SAHARAN toolbox provided a feasible and acceptable holistic assessment of child growth and function in mid-childhood. We found clear associations between growth, height-adjusted lean mass and physical function, but not cognitive function. The SAHARAN toolbox could be deployed to characterise school-age growth, development and function elsewhere in sub-Saharan Africa
Soil ingestion, nutrition and the seasonality of anthrax in herbivores of Etosha National Park
Abstract. Anthrax, caused by the bacterium Bacillus anthracis, is a seasonally occurring infectious disease affecting primarily herbivorous wildlife and livestock. The seasonality of anthrax outbreaks varies among locations, making it difficult to develop a single consistent ecological description of this disease. Over 44 years of mortality surveillance, most anthrax cases in Etosha National Park, Namibia are observed in the wet season, although elephants have an anthrax mortality peak in the dry season. Focusing on three host species (plains zebra, Equus quagga; African elephant, Loxodonta africana; and springbok, Antidorcas marsupialis) occupying the endemic anthrax area of Etosha National Park, Namibia, we tested two commonly posited causes of anthrax seasonality in herbivores: increased pathogen exposure due to greater soil contact, and increased host susceptibility due to seasonal nutritional stress. These hypotheses were assessed using fecal sampling and measurement of the percentage of fecal silicates as an index of soil ingestion and fecal nitrogen, phosphorus and crude fiber as nutritional indices. Nutritional quality for all three species was higher in wet than dry seasons. Comparing among wet seasons, nutritional indices showed either a decline in nutrition with increasing rainfall or no significant pattern. All three species had greater soil ingestion in the wet season than the dry season. Higher soil contact during the anthrax peak suggests that anthrax seasonality may in part be due to heightened exposure to B. anthracis in wet seasons, for zebra and springbok. Elephant anthrax deaths do not correspond with the season of increased soil ingestion or grazing, suggesting that other behavioral mechanisms may overshadow foraging-based risk factors for this species. Nutritional stress is unlikely the primary causative factor in wet season anthrax systems, although nutritional stress sufficient to reduce resistance is difficult to assess non-invasively in wild herbivores. In contrast, increased soil ingestion may be an important predisposing factor for wet season anthrax outbreaks. Ultimately, the amount of soil ingested and its importance in the transmission of soil-borne pathogens will vary based on foraging behaviors, intake rates, grassland structure and on the likelihood that foraging areas intersect with pathogen aggregations in the environment
How well does the process of screening and diagnosis work for HIV-infected persons identified with presumptive tuberculosis who are attending HIV care and treatment clinics in Harare city, Zimbabwe?
Background: Intensified TB case finding is recommended for all HIV-infected persons regularly attending HIV care and treatment clinics. The authors aimed to determine how well this system worked among HIV-infected patients diagnosed with presumptive TB in 14 health facilities of Harare province, Zimbabwe, between January and December 2016. Methods: Retrospective review using routine programme records. Results: Of 47 659 HIV-infected persons enrolled in HIV care, 102 were identified with presumptive TB through the programmatic electronic database. Of these, 23% (23/102) were recorded in presumptive TB registers and, of these 65% (15/23) were traced to laboratory registers. Of 79 patients not recorded in presumptive TB registers, 9% (7/79) were traced to laboratory registers. Of 22 patients in the laboratory register, all had negative sputum smears for acid-fast bacilli and 45% (10/22) had Xpert MTB/RIF assays with one positive result. Six patients altogether started anti-tuberculosis treatment, the median time from presumptive tuberculosis diagnosis to treatment being 12 days. The only significant risk factor for loss-to-follow-up between presumptive TB diagnosis and laboratory registration was not being recorded in presumptive TB registers. Conclusions: Follow-up mechanisms for presumptive TB cases diagnosed in HIV care clinics in Harare city need strengthening, particularly through improved documentation in presumptive TB registers and better Xpert MTB/RIF use
