Religious Education Syllabuses for Secondary School Teachers in Zambia: Catholic Missionaries’ Contributions

Received 14 August 2018. Accepted 13 September 2018. Published online 30 September 2018.Though widely acknowledged that the role of teacher training institutions remains crucial in providing an understanding of the educational basis for Religious Education (RE) and in improving the overall quality of provision in schools, both theoretical and empirical exploration of the syllabuses prepared for teachers in Zambian higher education is scanty. Informed by an interpretative case study on the RE syllabus prepared for teachers at Zambia Catholic University (ZCU), the paper argues that by embracing and revising the syllabus from Nkrumah College of Education, ZCU exemplified the stakeholder interest and missionary contributions in safeguarding that which had been envisioned in teacher education

Religion in Public Life: Rethinking the Visibility and Role of Religion as an Ethical Resource in the Transformation of the Higher Education Landscape in Post-1990 Zambia

Received 12 March 2019. Accepted 5 September 2019. Published online 5 October 2019.This article revisits the relationship between religion and education in post-1990 to understand the growing public role of religion in higher education in Zambia. The aim of the study that informs the article was to understand the public role of religion through the example of Catholicism in university education provision in Zambia. Informed by interpretivism and interpretive phenomenology, data were gathered through interviews with purposively chosen Catholic Church, Catholic university education representatives, and document analysis, and reductively explicated. Largely in conversation with the discourses of religious resources, the article demonstrates that the growing visibility of the Catholic Church on the Zambian university education landscape after the 1990s was driven by the quest to serve the needs of the Church, the principles of Catholic education and the society, thereby contributing to the transformation of the higher education landscape. The article argues that contrary to projections that secularisation would lead to a decline of religion in public life, religion had remained a useful ethical resource for the transformation of university education provision in post-1990 Zambia underpinned by an ethical concern to promote social and individual wellbeing and support the state’s expansion of higher education

Breeding in bambara groundnut (Vigna subterranea (L.) Verdc.): strategic considerations

Bambara groundnut (Vigna subterranea (L.) Verdc.) has a large number of landraces throughout Africa where small-scale farmers have preserved its genetic diversity on-farm. To date, the full genetic diversity of the crop remains largely unexploited. Until recently bambara groundnut never received any appreciable research effort, especially for its genetic improvement. Until then, only selection breeding was practised in which existing landraces were evaluated and their seeds multiplied. However, no new combinations resulting from hybridisation had ever been produced. Recently, collaborative research efforts involving partners from Africa and Europe have produced the first crosses of bambara groundnut. The creation of these crosses is a significant scientific and practical achievement and opens up the possibility of breeding true varieties of this crop. This paper shows how different strategies have been combined to establish the basis of a strategic breeding programme in bambara groundnut. The paper also illustrates the use of landraces in the bambara groundnut breeding programme, as an example of the contribution that landraces can make to increasing productivity in marginal environments and the conservation of a crop's genetic resources on-farm.African Journal of Biotechnology Vol. 4 (6), pp. 463-471, 200

Effect of nitrogen-rich cell culture surfaces on type X collagen expression by bovine growth plate chondrocytes

Background: Recent evidence indicates that osteoarthritis (OA) may be a systemic disease since mesenchymal stem cells (MSCs) from OA patients express type X collagen, a marker of late stage chondrocyte hypertrophy (associated with endochondral ossification). We recently showed that the expression of type X collagen was suppressed when MSCs from OA patients were cultured on nitrogen (N)-rich plasma polymer layers, which we call "PPE:N" (N-doped plasma-polymerized ethylene, containing up to 36 atomic percentage (at.%) of N.Methods: In the present study, we examined the expression of type X collagen in fetal bovine growth plate chondrocytes (containing hypertrophic chondrocytes) cultured on PPE:N. We also studied the effect of PPE: N on the expression of matrix molecules such as type II collagen and aggrecan, as well as on proteases (matrix metalloproteinase-13 (MMP-13) and molecules implicated in cell division (cyclin B2). Two other culture surfaces, "hydrophilic" polystyrene (PS, regular culture dishes) and nitrogen-containing cation polystyrene (Primaria (R)), were also investigated for comparison.Results: Results showed that type X collagen mRNA levels were suppressed when cultured for 4 days on PPE: N, suggesting that type X collagen is regulated similarly in hypertrophic chondrocytes and in human MSCs from OA patients. However, the levels of type X collagen mRNA almost returned to control value after 20 days in culture on these surfaces. Culture on the various surfaces had no significant effects on type II collagen, aggrecan, MMP-13, and cyclin B2 mRNA levels.Conclusion: Hypertrophy is diminished by culturing growth plate chondrocytes on nitrogen-rich surfaces, a mechanism that is beneficial for MSC chondrogenesis. Furthermore, one major advantage of such "intelligent surfaces" over recombinant growth factors for tissue engineering and cartilage repair is potentially large cost-saving

Effect of HIV self-testing on the number of sexual partners among female sex workers in Zambia: A randomized controlled trial

Objectives: To assess the effect of two health system approaches to distribute HIV selftests on the number of female sex workers’ client and nonclient sexual partners. Design: Cluster randomized controlled trial. Methods: Peer educators recruited 965 participants. Peer educator–participant groups were randomized 1 : 1 : 1 to one of three arms: delivery of HIV self-tests directly from a peer educator, free facility-based delivery of HIV self-tests in exchange for coupons, or referral to standard-of-care HIV testing. Participants in all three arms completed four peer educator intervention sessions, which included counseling and condom distribution. Participants were asked the average number of client partners they had per night at baseline, 1 and 4 months, and the number of nonclient partners they had in the past 12 months (at baseline) and in the past month (at 1 month and 4 months). Results: At 4 months, participants reported significantly fewer clients per night in the direct delivery arm (mean difference 0.78 clients, 95% CI 1.28 to 0.28, P ¼ 0.002) and the coupon arm (0.71, 95% CI 1.21 to 0.21, P ¼ 0.005) compared with standard of care. Similarly, they reported fewer nonclient partners in the direct delivery arm (3.19, 95% CI 5.18 to 1.21, P ¼ 0.002) and in the coupon arm (1.84, 95% CI 3.81 to 0.14, P ¼ 0.07) arm compared with standard of care. Conclusion: Expansion of HIV self-testing may have positive behavioral effects enhancing other HIV prevention efforts among female sex workers in Zambia.

Stakeholders' Participation in Planning and Priority Setting in the Context of a Decentralised Health Care system: the case of prevention of mother to child Transmission of HIV Programme in Tanzania.

In Tanzania, decentralisation processes and reforms in the health sector aimed at improving planning and accountability in the sector. As a result, districts were given authority to undertake local planning and set priorities as well as allocate resources fairly to promote the health of a population with varied needs. Nevertheless, priority setting in the health care service has remained a challenge. The study assessed the priority setting processes in the planning of the prevention of mother to child transmission of HIV (PMTCT) programme at the district level in Tanzania. This qualitative study was conducted in Mbarali district, south-western Tanzania. The study applied in-depth interviews and focus group discussions in the data collection. Informants included members of the Council Health Management Team, regional PMTCT managers and health facility providers. Two plans were reported where PMTCT activities could be accommodated; the Comprehensive Council Health Plan and the Regional PMTCT Plan that was donor funded. As donors had their own globally defined priorities, it proved difficult for district and regional managers to accommodate locally defined PMTCT priorities in these plans. As a result few of these were funded. Guidelines and main priority areas of the Ministry of Health and Social Welfare (MoHSW) also impacted on the ability of the districts and regions to act, undermining the effectiveness of the decentralisation policy in the health sector. The challenges in the priority setting processes revealed within the PMTCT initiative indicate substantial weaknesses in implementing the Tanzania decentralisation policy. There is an urgent need to revive the strategies and aims of the decentralisation policy at all levels of the health care system with a view to improving health service delivery

Institutionalizing Provider-Initiated HIV Testing and Counselling for Children: An Observational Case Study from Zambia

Background: Provider-initiated testing and counselling (PITC) is a priority strategy for increasing access for HIV-exposed children to prevention measures, and infected children to treatment and care interventions. This article examines efforts to scale-up paediatric PITC at a second-level hospital located in Zambia’s Southern Province, and serving a catchment area of 1.2 million people. Methods and Principal Findings: Our retrospective case study examined best practices and enabling factors for rapid institutionalization of PITC in Livingstone General Hospital. Methods included clinical observations, key informant interviews with programme management, and a desk review of hospital management information systems (HMIS) uptake data following the introduction of PITC. After PITC roll-out, the hospital experienced considerably higher testing uptake. In a 36-month period following PITC institutionalization, of total inpatient children eligible for PITC (n = 5074), 98.5 % of children were counselled, and 98.2 % were tested. Of children tested (n = 4983), 15.5 % were determined HIVinfected; 77.6 % of these results were determined by DNA polymerase chain reaction (PCR) testing in children under the age of 18 months. Of children identified as HIV-infected in the hospital’s inpatient and outpatient departments (n = 1342), 99.3 % were enrolled in HIV care, including initiation on co-trimoxazole prophylaxis. A number of good operational practices and enabling factors in the Livingstone General Hospital experience can inform rapid PIT

Effect of pathology type and severity on the distribution of MRI signal intensities within the degenerated nucleus pulposus: application to idiopathic scoliosis and spondylolisthesis

<p>Abstract</p> <p>Background</p> <p>Disc degeneration is characterized by a loss of cellularity, degradation of the extracellular matrix, and, as a result, morphological changes and biomechanical alterations. We hypothesized that the distribution of the MR signal intensity within the nucleus zone of the intervertebral disc was modified according to the pathology and the severity of the pathology. The objective of this study was to propose new parameters characterizing the distribution of the signal intensity within the nucleus zone of lumbar intervertebral discs, and to quantify these changes in patients suffering from spondylolisthesis or idiopathic scoliosis.</p> <p>Methods</p> <p>A retrospective study had been performed on T2-weighted MR images of twenty nine patients suffering from spondylolisthesis and/or scoliosis. The high intensity zone of the nucleus pulposus was semi-automatically detected. The distance "DX" between the center weighted by the signal intensity and the geometrical center was quantified. The sum of the signal intensity on the axis perpendicular to the longitudinal axis of the disc was plotted for each position of the longitudinal axis allowing defining the maximum sum "SM" and its position "PSM".</p> <p>Results</p> <p>"SM" was clearly higher and "PSM" was more shifted for scoliosis than for spondylolisthesis. A two-way analysis of variance showed that the differences observed on "DX" were not attributed to the pathology nor its severity, the differences observed on "SM" were attributed to the pathology but not to its severity, and the differences observed on "PSM" were attributed to both the pathology and its severity.</p> <p>Conclusions</p> <p>The technique proposed in this study showed significant differences in the distribution of the MR signal intensity within the nucleus zone of intervertebral discs due to the pathology and its severity. The dependence of the "PSM" parameter to the severity of the pathology suggests this parameter as a predictive factor of the pathology progression. This new technique should be useful for the early diagnosis of intervertebral disc pathologies as it highlights abnormal patterns in the MRI signal for low severity of the pathology.</p
