Leadership in the African context
The Western world has always viewed the African continent as plagued by corruption; dictatorship; military coups; rebellious leaders; greediness; misuse of power; and incompetent, politically unstable leaders - in effect, suspicious leaders who undermine their own democracies. This paper analyzes African leadership and its impact by concentrating on three historical eras, namely; the African Religious era; the Christian era, and the era of Globalization. These affected African leadership. In addition, many brilliant minds left the continent in search of greener pastures. A review of these three eras will help us understand how leadership shifted from African values into Western concepts. The role of missionaries lead African people to live with both an African and a Western concept of life. In spite of the above problems, our past leaders did their best in addressing the difficulties they faced during the three eras. African concepts of leadership were often regarded as barbaric and uncultured. Structures were evaluated by Western standards. Due to globalisation, African leaders, through programmes like NEPAD, are going back to basics, drawing on African concepts of unity among its leadership. Effectiveness or life-giving leadership is emerging and empowering villagers/communities in the continent. This type of leadership is innovative and has brought new hope for the continent
Aristotle's philosophical influence on Western civilization, history and theology placed women in inferior positions
This paper examines the influence of Aristotle on western civilization, and it explores how this line of thinking influenced religion from the point of view of its subordination of women. Then I examine how women were excluded from historical accounts and by this omission, were treated generally and regarded as inferior beings. Next I analyze the critical feminist reaction to this male patriarchal authorship, and then examined the research methods that patriarchal writers used with patriarchal reference to the “traditional model” (i e, male as a norm in society). I will finally examine certain oppressive scriptural passages, which oppress women and help men to regard them as property. The above concept helped feminist to research a new methodology of liberation, not only to liberate women but men as well
What next in mission? From the end of the earth to Jerusalem
This article sketches the impact of technology and globalisation on culture, and the results appear to be devastating. An appeal is made to churches to encourage missionary endeavours that reach out to the world. The challenge that African Churches face is, how they will take mission work, from the ends of the earth back to Jerusalem (Missionary Churches). A plea is made to pay respect to the creation of God, and to restore broken relationships. �Let thy Kingdom come�, is the final prayer
The relationship between depression symptoms and academic performance among first-year undergraduate students at a South African university
DATA AVAILABILITY : The data that support the findings of this study are available from the
University Registrar of the University of the Witwatersrand, Johannesburg,
but restrictions apply to the availability of these data, which were used
under license for the current study, and so are not publicly available. Data are
however available from the corresponding author upon reasonable request
and with permission of the University Registrar of the University of the
Witwatersrand, Johannesburg.BACKGROUND : South African universities face a challenge of low throughput rates, with most students failing to
complete their studies within the minimum regulatory time. Literature has begun to investigate the contribution
of well-being, including mental health, with depression among students being one of the most common mental
disorders explored. However, locally relevant research exploring associations between depression and academic
performance has been limited. This research hypothesizes that the presence of depression symptoms, when
controlling for key socio-demographic factors, has an adverse impact on student academic outcomes and contributes
to the delay in the academic progression of students.
METHODS : The study used a cross-sectional design. Data were collected in 2019 from first-time, first-year
undergraduate students using a self-administered online questionnaire. In total, 1,642 students completed the survey.
The Patient Health Questionnaire-9 (PHQ-9) was used to screen for depression symptoms. Data on students’ academic
performance were obtained from institutional records. Bivariate and multivariate regression analyses were used to
examine associations between depression symptoms and academic performance.
RESULTS : Most participants (76%) successfully progressed (meeting the requirements to proceed to the second year
of university study). Of the participants, 10% displayed symptoms of severe depression. The likelihood of progression
delay (not meeting the academic requirements to proceed to the second year of university study) increased with the
severity of depression symptoms. Moderate depression symptoms nearly doubled the adjusted odds of progression
delay (aOR = 1.98, 95% CI: 1.30-3.00, p = 0.001). The likelihood of progression delay was nearly tripled by moderate
severe depression symptoms (aOR = 2.70, 95% CI:1.70–4.36, p < 0.001) and severe depression symptoms (aOR = 2.59,
95% CI:1.54–4.36, p < 0.001). The model controlled for field of study, financial aid support as well as sex and race.
CONCLUSION : Higher levels of depression symptoms among first-year university students are associated with a greater
likelihood of progression delay and may contribute to the low throughput rates currently seen in South African universities. It is important for students, universities and government departments to recognize student mental
wellness needs and how these can be met.The Kresge Foundation and the South African National Research Foundation.http://www.biomedcentral.com/bmcpublichealtham2023Paraclinical Science
Reorientation-effect measurement of the first 2+ state in 12C : Confirmation of oblate deformation
A Coulomb-excitation reorientation-effect measurement using the TIGRESS γ−ray spectrometer at the TRIUMF/ISAC II facility has permitted the determination of the 〈21 +‖E2ˆ‖21 +〉 diagonal matrix element in 12C from particle−γ coincidence data and state-of-the-art no-core shell model calculations of the nuclear polarizability. The nuclear polarizability for the ground and first-excited (21 +) states in 12C have been calculated using chiral NN N4LO500 and NN+3NF350 interactions, which show convergence and agreement with photo-absorption cross-section data. Predictions show a change in the nuclear polarizability with a substantial increase between the ground state and first excited 21 + state at 4.439 MeV. The polarizability of the 21 + state is introduced into the current and previous Coulomb-excitation reorientation-effect analyses of 12C. Spectroscopic quadrupole moments of QS(21 +)=+0.053(44) eb and QS(21 +)=+0.08(3) eb are determined, respectively, yielding a weighted average of QS(21 +)=+0.071(25) eb, in agreement with recent ab initio calculations. The present measurement confirms that the 21 + state of 12C is oblate and emphasizes the important role played by the nuclear polarizability in Coulomb-excitation studies of light nuclei
Performance evaluation of the Pima™ point-of-care CD4 analyser using capillary blood sampling in field tests in South Africa
<p>Abstract</p> <p>Background</p> <p>Point-of-care CD4 testing can provide immediate CD4 reporting at HIV-testing sites. This study evaluated performance of capillary blood sampling using the point-of-care Pima™ CD4 device in representative primary health care clinics doing HIV testing.</p> <p>Methods</p> <p>Prior to testing, prescribed capillary-sampling and instrument training was undertaken by suppliers across all sites. Matching venous EDTA samples were drawn throughout for comparison to laboratory predicate methodology (PLG/CD4). In Phase I, Pima™ cartridges were pipette-filled with EDTA venous blood in the laboratory (N = 100). In Phase II (N = 77), Pima™ CD4 with capillary sampling was performed by a single operator in a hospital-based antenatal clinic. During subsequent field testing, Pima™ CD4 with capillary sampling was performed in primary health care clinics on HIV-positive patients by multiple attending nursing personnel in a rural clinic (Phase-IIIA, N = 96) and an inner-city clinic (Phase-IIIB, N = 139).</p> <p>Results</p> <p>Pima™ CD4 compared favourably to predicate/CD4 when cartridges were pipette-filled with venous blood (bias -17.3 ± STDev = 36.7 cells/mm<sup>3</sup>; precision-to-predicate %CV < 6%). Decreased precision of Pima™ CD4 to predicate/CD4 (varying from 17.6 to 28.8%SIM CV; mean bias = 37.9 ± STDev = 179.5 cells/mm<sup>3</sup>) was noted during field testing in the hospital antenatal clinic. In the rural clinic field-studies, unacceptable precision-to-predicate and positive bias was noted (mean 28.4%SIM CV; mean bias = +105.7 ± STDev = 225.4 cells/mm<sup>3</sup>). With additional proactive manufacturer support, reliable performance was noted in the subsequent inner-city clinic field study where acceptable precision-to-predicate (11%SIM CV) and less bias of Pima™ to predicate was shown (BA bias ~11 ± STDev = 69 cells/mm<sup>3</sup>).</p> <p>Conclusions</p> <p>Variable precision of Pima™ to predicate CD4 across study sites was attributable to variable capillary sampling. Poor precision was noted in the outlying primary health care clinic where the system is most likely to be used. Stringent attention to capillary blood collection technique is therefore imperative if technologies like Pima™ are used with capillary sampling at the POC. Pima™ CD4 analysis with venous blood was shown to be reproducible, but testing at the point of care exposes operators to biohazard risk related to uncapping vacutainer samples and pipetting of blood, and is best placed in smaller laboratories using established principles of Good Clinical Laboratory Practice. The development of capillary sampling quality control methods that assure reliable CD4 counts at the point of care are awaited.</p
Coulomb excitation of and a change in structure approaching N = Z = 40
Background: Nuclei approaching are known to exhibit strongly deformed structures and are thought to be candidates for shape coexistence. In the krypton isotopes, are poorly characterized, preventing an understanding of evolving deformation approaching . Purpose: The present work aims to determine electric quadrupole transition strengths and quadrupole moments of in order to better characterize their deformation. Conclusions: Comparison of measured and values indicates that neutron-deficient () isotopes of krypton are closer to axial deformation than other isotopic chains in the mass region. A continuation of this trend to higher may result in Sr and Zr isotopes exhibiting near-axial prolate deformation. Methods: Sub-barrier Coulomb excitation was employed, impinging the isotopes of krypton on and targets. Utilizing a semiclassical description of the safe Coulomb-excitation process matrix elements could then be determined. Results: Eleven new or improved matrix elements are determined in and seven in . The new value in disagrees with the evaluated value by , which can be explained in terms of deficiencies in a previous Coulomb-excitation analysis
Exploring the relationship between food insecurity with hunger and academic progression at a large South African University
Food insecurity has been recognized as one of the key challenges currently affecting students in higher education. However, there has been limited research in South African higher education that has sought to understand the relationship between food insecurity and student success. The current study defined student success as a student meeting the requirements to progress from one year of study to another. The study aimed to understand the relationship between food insecurity and student academic progression. Further to this, it aimed to understand the prevalence of food insecurity, and the characteristics of students most likely to progress. This study was carried out at a large South African university and targeted at the entire 2019 first-time, first year undergraduate student cohort (n=5 356). All eligible students were invited via email to participate in a self-administered, online cross-sectional survey. The Household Food Insecurity Access Scale (HFIAS) was used to measure student food insecurity. Data were linked to the end of the year academic progress outcomes, which indicated whether or not students had met the requirements to progress to the following year of study. The survey was completed by 1 612 students, giving a 30 per cent response rate. Overall, nearly a quarter of the students (23%) were found to be experiencing food insecurity with hunger, with 5 per cent experiencing severe hunger. A retention rate of 94 per cent was recorded, and a little over 70 per cent of participants progressed to the second year of study. Student academic progression was found to be significantly associated with food security status (p<0.001), as well as first generation status (p=0.007) and home location (p<0.001) in the bivariate analysis. Further to this, a multivariate analysis revealed that students experiencing little to no hunger were almost twice as likely to progress to the next year of study when compared to those experiencing food insecurity with hunger (Odds Ratio [OR]=1.876; 95% Confidence Interval [CI]: 1.454-2.418; p<0.001). The results of this study demonstrated that food insecurity with hunger was negatively associated with student academic progression. This is one of the first, and largest, South African studies to demonstrate this relationship. This work advocates for students experiencing food insecurity with hunger to be prioritised in university student support programmes, such as food security interventions, as this may improve student success
