Lay Beliefs And Responses Concerning HypertensionAnd Its Management In Two CulturallyDistinct Groups
Objective: To determine quantitatively whether there are significant differences in lay beliefs about hypertension and its management between African- Caribbean (A.C.) living in the UK but born in the West Indian Caribbean Islands and white hypertensive patients in the UK.
Design: Self-administered postal (and surgery) questionnaire.
Setting: Two general practices in the Wembley / North London and Dagenham (Essex) areas.
Participants: Male and female patients aged between 35 and 69 years of age registered with the above practices and receiving treatment for hypertension. These were selected from the age/sex/disease registers.
Interventions: None
Main outcome Measures: African-Caribbean vs. White/Caucasian responses to the 16-item questionnaire and determining statistical significance (the P value). This was done to determine whether or not there are significant differences in lay beliefs between the two ethnic groups i.e.A.C. versus white Caucasian.
Results: Out of 525 patients who were sent the 16-item questionnaire, there were 427 responses (238 men, 189 women). This was an 81% response rate. In terms of race, there were 224 white and 203 African-Caribbean respondents. The responses to the questions strongly suggested that there are significant ethnic differences on matters of lay beliefs regarding hypertension and its management. This quantitative study supported the findings and conclusions of a previous (1988) qualitative one by Myfawny Morgan and C.J.Watkins on the same subject.
Conclusions: Lay beliefs appear to be extremely important amongst all cultures and it would appear that these do have an impact on how an individual views his or her medical condition and how the doctors manage it. Intercontinental and international encounters appear to be here with us to stay due to a variety of factors e.g. trade, education, sports and wars. It is therefore of utmost importance that medical practitioners bear this in mind in their encounters with patients. An acceptance of this approach by all doctors and health workers may improve compliance.

Pervasive skills and accounting graduates’ employment prospects: Are South African employers calling for pervasive skills when recruiting?
In today’s global and digital accounting world, the role and skills required of accounting practitioners have evolved, resulting in pervasive skills coming to the fore. Various Interventions, including changes made to the accounting degree curricula for an added focus on pervasive skills, have been made by universities offering accounting programmes in South Africa. However, it remains unknown whether such interventions provide an incentive for accounting graduates in the job-seeking process. In as much as the possession of pervasive skills may be associated with employment success, it is not clear whether employers are actually calling for these skills. Through a content analysis of advertised online accounting vacancies, this quantitative study sought to investigate the importance of pervasive skills for accounting graduate employment prospects. The findings suggested that oral and written communication skills and critical thinking skills were the most sought after pervasive skills in accounting-related employment in South Africa.
 
The Impact of Using Derivatives as a Hedging Instrument in Supporting Global Development Trends: An Analysis of the African Aviation Sector
With less than a decade before the impending deadline for the realisation of the United Nations 2030 Sustainable Agenda for Development and with the Covid-19 pandemic having significantly slowed down progress on the Sustainable Development Goals (SDGs), aggressive collaborative efforts from all sectors of the global economy are required now more than ever, not only for the achievement of the targeted goals but also to aid in an inclusive global economic recovery. With the global airline industry having been identified as one of the key pillars for propelling this agenda forward as it is believed to contribute to at least 15 of the 17 SDGs, exploring ways in which this industry can remain profitable and sustainable, so it continues to contribute towards the unified goal has become an important focus area for those at the forefront of the agenda. One of the identified major threats to the longevity and prosperity of the airline industry is said to be the inherent exposure to the volatility in commodity markets, as fuel expenditure generally makes up the single largest cost component of an airline's operating expense. This dissertation, therefore, investigates the relationship between fuel hedging and the firm value of commercial airlines in order to establish the effectiveness of fuel hedging as a potential lever that can be used to effect the desired change towards the realisation of the SDGs. The study draws on evidence from African, European and North American airlines and makes use of a panel least square estimation technique to estimate the behaviour of the parameters in the selected statistical sample over a 10-year period from 2009 to 2019. Using Tobin's Q as a proxy for firm value, the study computes a series of regressions, incorporating different control variables such as airline size, percentage of jet fuel cost to total operating costs, jet fuel cost per passenger, and profit per passenger - which are all deemed to have significant explanatory power to allow for the isolation of the effect of fuel price hedging. The study further makes use of two hedging variables (percentage hedged and fair value of hedging derivatives to assets) in separate regression equations to ascertain their individual relationships with the dependent variable - Tobin's Q. The analysis of the results in this dissertation reveals a positive correlation between the airlines' hedging activity and airline firm value thereby suggesting that mitigating the risks associated to fuel price volatility could yield positive outcomes for firm value. These findings can prove to be useful for those at the forefront of the 2030 global development agenda, as well as the airline companies themselves in driving the SDG goals

In vitro assessment of selected ethno-medicinal plants as potential alternatives for the control of gastrointestinal nematodes in sheep and goats.
Masters Degree. University of KwaZulu-Natal, Pietermaritzburg.Commercial anthelmintics are becoming ineffective against gastrointestinal nematodes (GIN) of ruminants due to development of resistant parasites. Research is exploiting anthelmintic ethno-medicinal plants for an alternative remedy. This study assessed the in vitro: (1) dose activity at different concentrations, (2) combined synergistic activity of ethanolic crude plant extracts on mixed GIN of sheep and goats; and (3) cytotoxic activity of these extracts on kidney vero cells. During assessment of in vitro dose activity, faecal samples of sheep and goats that were grazing on contaminated pasture were collected, cultured (12 days) to L3 larvae stage, and treated with 40, 20, 10, 5, 2.5, 1.25 and 0.25% v/v of Allium cepa, Ananas comosus, Bidens pilosa, Carica papaya, Crinium macowanii, Gunnera perpensa, Nicotiana tabacum, Ricinus communis, Sarcosterma viminale, Trema orientalis, Urtica dioica, Vernonia amygdalina, Zanthozylum capense, Zingiber officinale, Zizyphus mucronata and Aloe vanbalenii extracts. Larvae were subjected to Baermann technique for isolation and later observed under a microscope (10x objective). During the assessment of synergism at 1.25% v/v concentration (1:1), 28 crude plant extract combinations from eight (8) mostly edible plants namely: Allium cepa, Ananas comosus, Bidens pilosa, Carica papaya, Vernonia amygdalina, Zingiber officinale, Aloe vanbalenii and Nicotiana tabacum (inedible) were tested for their synergistic activity. The simple and Webb’s fractional product method were used to compute interactions of crude plant extract combinations. During assessment of cytotoxic activity MTT assay was used to assess effect of 16 individual plant extracts mentioned above on vero kidney cells.
Results revealed that goats had a significantly higher efficacy than sheep at 40% (P=0.0253) and 20% (P=0.038) concentration (v/v); but goats had significantly lower efficacy at concentration (v/v) 1.25% (P= 0.0305) and 0.625% (P= 0.0158) relative to sheep. On the other hand, both goats and sheep had insignificant (P>0.05) efficacy for CPEs concentration (v/v) 10%, 5% and 2.5%. Plant species had no effect on efficacy at concentration (v/v) 40%, 20%, 10%, 5%, 2.5%, but had significant effect at lowest concentration (v/v) of 1.25 % (P=0.0085%) and 0.625 (P=0.0234%) which was not dose-dependent. Few plants had high activities at the lowest tested concentration (0.625% v/v). In goats it was Gunnera perpensa (89.47%±12.40), while in sheep Gunnera perpensa (100%±12.40), Urtica dioica (95.24%±12.40), Zizyphus mucronata (90.47%±12.40), Allium cepa (90.47%±12.40), Aloe vanbalenii (85.71%±12.40) and Bidens pilosa (80.95%±12.40). Interactions following Webb’s fractional product method were antagonistic and synergistic, whereas those following simple method yielded synergistic interactions only. In goats, V. amygdalina + Z. officinale (100%) was the most efficacious, while in sheep, A. cepa + C. papaya (100%), V. amygdalina + Z. officinale (100%), V. amygdalina + Z. officinale (100%) and A. comosus + N. tabacum (100%) were most efficacious. Animal species had a significant effect (P0.05) the efficacy of crude plant extract combinations. Vernonia amygdalina (IC50 = 0.01 mg/ml) followed by Zingiber officinale (IC50 =0.02 mg/ml) were the most cytotoxic crude extracts, while Allium cepa (IC50 = 0.27) and Aloe vanbalenii (IC50 = 0.22 mg/ml) were the least cytotoxic crude extracts. Cytotoxicity increased in a dose dependent manner. The concentration-cell viability relationship was negative linear in most crude plant extracts. While it was negative quadratic for Gunnera perpensa, Zingiber officinale and Vernonia amygdalina. Anthelmintic crude plant extracts are efficacious against GIN of sheep and goats. Although they are mostly harmless minimum effective concentration should be used. Crude plant extracts that were efficacious at the lowest concentration and observed synergistic crude plant extract combinations should be tested in vivo.

Factors contributing to failure of student nurses in biological nursing sciences: KwaZulu-Natal College of Nursing
Biological nursing science, also known as Bioscience, is a difficult subject or module in nurse training and education worldwide. In the four-year comprehensive nursing diploma programme, Biological Nursing Science (BNS) is one of the core subjects taught in the first year. One of the major bioscience concepts integrated in the undergraduate nursing curriculum is Anatomy and Physiology (A&P). It is essential for students to pass A&P before enrolling for GNS because the two subjects provide details of the normal structures of the body and how they function, which is the foundation of GNS.
The failure of students in BNS (Anatomy and Physiology) enrolled for the Diploma in Nursing (General, Psychiatry and Community) and Midwifery is of great concern to the nurse educators and campus principals at the KwaZulu-Natal College of Nursing. The results for the BNS module between 2014 and 2017 indicated that students had problems with the course. Accordingly, the researcher wished to determine the factors that contributed to student failure in BNS (Anatomy and Physiology) in the KwaZulu-Natal College of Nursing.
The aim of the study was to identify factors that contributed to the BNS failure rate and make recommendations to improve the pass rate in BNS. The researcher used Jeffreys’ (2013) NURS model as the conceptual framework to examine the influence of student profile characteristics, academic factors, environmental factors and psychological outcomes on Anatomy and Physiology performance. A quantitative, non-experimental, descriptive research design was selected to describe, explain, and predict factors contributing to students’ failure in BNS. Data was collected from 114 respondents by means of a Likert scale-based self-administered structured questionnaire.The study found that shorter breaks between lectures, which caused exhaustion; the one-day study time between examinations; two hours for the subject examination, and educators not involving students in lessons or providing after-class sessions were among the factors contributing to the high failure rate. It is recommended that the curriculum allow sufficient notional hours for teaching; learner support programmes be introduced to assist students who need help; examination timetables be adjusted to allow adequate study and preparation time, and educators involve students in active learning. Recommendations are also made for further research.Health StudiesM.A. (Health Studies
