  • Description: Helicobacter pylori, a neutralophile chronically infects the gastric stomach of more than half of the world’s population. Infection with the organism is associated with acute or chronic duodenal/gastric ulcer disease, gastritis, gastric adenocarcinoma, mucosa-associated tissue lymphoma (MALT) and primary B-cell gastric lymphoma and has been grouped as a class one carcinogen by the World Health Organisation (WHO). Prevalence of this organism is very high in developing countries especially in Africa, including South Africa. H. pylori treatment using the common first and second line regimens, triple therapy with two antibiotics and a proton pump inhibitor (PPI) is showing inefficiency due to increasing drug resistance. However, newly developed treatment regimens seem to be more expensive and are accompanied by more side effects. Honey contains phytochemicals which are a wealthy source of biologically active compounds some of which have been put into good use in the pharmaceutical industry. Pathogenesis of H. pylori infection in the human stomach relies on several virulence factors which include the urease enzyme, cagA and vacA. The urease enzyme actively hydrolyses urea to produce ammonia an important by-product involved in pH regulation favouring the survival of the organism in the acidic human stomach. This study therefore focuses on screening for anti-urease solvent extracts of South African honey, and evaluate whether inhibition of urease offsets the growth of H. pylori under acidic conditions. Locally produced natural honeys; Bush honey, Raw honey, Gold Crest honey, Q Bee honey, Little Bee honey, Fleures honey-radurised, Siyakholwa pure honey and Manuka honey; an import from New Zealand were purchased and the method by Syazana et al. (2010) was used for the extraction of compounds in honey. A standard strain ATCC 43526 (American Type Culture Collection, Manassas, VA, USA) and 48 pure cultures obtained from clinical isolates cultured from gastric corpus biopsy specimen of patients with gastric morbidities who were ix visiting the endoscopy unit in Livingstone Hospital, Port Elizabeth between June 2008 to December 2008 were initially used as source of urease enzyme as per extraction method done by Amin et al. (2013), but with modifications. Prior to urease extraction, H. pylori strains were identified by biochemical tests (urease, catalase, oxidase, Gram stain), confirmed by PCR targeting the glmM gene (140 bp) and drug resistance profiling was done on all the 48 strains according to Seanego et al. (2012). The screening for anti-urease active compounds was done according to Kaltwasser et al. (1966), a method relying on the reduction of NADH in a coupled urease dehydrogenase (GDH) system. Acetohydroxamic acid was used as a standard inhibitor. Prevalence of cytotoxin-associated gene A (cagA) gene and vacuolating cytotoxin gene A (vacA) gene was determined among all 48 clinical samples. The standard strains of H. pylori, X47 (cagA positive), J99 (vacA s1m1) and Tx30a (s2m2) were used as positive controls. H. pylori’s growth was then monitored under acidic pH in a cocktail spiked with anti-urease compounds (test samples) and in a cocktail without anti-urease compounds (negative control). Acetohydroxamic acid was used as a standard urease inhibitor. H. pylori multiplication was monitored in Brain Heart Infusion Broth (BHIB) adjusted to pH of 2, 3, 4, 5, 6 and 7. The strain MP01 was used as a standard urease negative strain while X47 and J99 were used as positive standards for cagA and vacA s1m1 respectively. The compounds that had anti-urease activity and were successful towards suppressing the multiplication of H. pylori under acidic environment, all other factors optimised, were subjected to gas chromatograph mass spectrometry (GC-MS) and liquid chromatograph spectrometry (LCMS) to determine volatile compounds and drugs in honey extracts respectively. The findings of this study revealed that at a concentration of 50 mg/mL, urease inhibition by petroleum ether extracts of Gold Crest and Fleures honey, hexane extracts of Little Bee and Manuka honey, and chloroform extracts of Bush honey and Q Bee honey had a range above or equal to 50 percent and there was no significance difference in urease inhibition percentage (I percent) of urease from different sources including that extracted from drug resistant H. pylori (p >0.05). Virulence factors are important for the pathogenesis of H. pylori. All the 48 clinical isolates were glmM (140 bp) positive and cagA was detected in 97.9 percent of the test isolates. The vacA gene was detected in all isolates but with different subtypes. The vacA allelic combination s1m1 was detected in 75 percent of the test isolates and s1m2 allelic combination was detected in 16.7 percent of the test isolates while the combination s2m2 was detected in 8.3 percent of the test isolates. None of the test isolates possessed the allelic combination s2m1. When H. pylori multiplication was monitored under acidic conditions in the presence of anti-urease active compounds, it was revealed that anti-urease active compounds in honey are capable of inhibiting the normal multiplication of H. pylori strains that are cagA positive, vacA positive and drug resistant. The GC-MS analysis showed that Fleures honey (urease I percent = 67.8 – 68.5 percent) and Gold Crest honey (urease I percent = 50.9 percent – 53.3 percent), all petroleum ether extracts had 27 and 26 volatile compounds. The hexane extract of Manuka honey (urease I percent = 50.0 – 53.2) had 43 compounds detected. The chloroform extract of Q Bee (urease I percent = 64.2 – 66.2 percent) had 13 volatile compounds detected. All the volatile compounds considered as representative samples of GC-MS analysis had a spectral matching ≥ 90 percent with the NIST11 library. However, the majority of compounds that were detected by LC-MS in representative honey extracts include vardenafil, urapidil, hydrocortisone, e.t.c which are drugs commonly used in the treatment of different ailments or infections that affect human beings. In addition, two xi drugs, sulfaquinoxaline and hydroxyquinoline which are used in veterinary medicine and antiseptic, disinfectant and pesticide applications in agricultural activities were detected in Little Bee honey. We therefore conclude that inhibition of urease has a bactericidal effect on drug resistant, cagA positive and vacA positive H. pylori strains growing under acidic environment.

  • Description: This study, assessment of national small and medium scale policy as a driver of local economic development: a case study of Ife Central Local Government, Nigeria, was undertaken to find out if the National SME policy in Nigeria has performed its critical role of driving the local economic and if not, why, and also to identify measures to solve the problems that are hindering the implementation of the National SMEs policy. This study will therefore investigate the contributions of the Small and Medium Enterprises sub-sector of the Nigerian economy, its problems and prospects and also examine the National SME policy and the importance of the policy. The objective of this study is to explore the implementation of National SME policy as a driver of local economic development, analyse the challenges that are associated with implementing the National SME policy in Ife Central Local Government and make recommendations regarding the implementation of SME policy in Nigeria. A total of 5 MP’s were randomly selected from a cross section of 7 MP’s that represent Ife Central Local Government. Interviews was used to determine how the National SME policy is been implemented in there constituency and if they are facing any challenges as to the implementing the policy and how are they solving the problems that are associated with the policy. The major findings of this study include the following: the National SME policy is an important policy which if well implemented would help the development of SMEs and also have great impact on the local economic development. Among the problems associated with the policy according to the MP’s are financial problems, illiteracy level of people in their constituency, Land segmentation problem, marketing problems. This study therefore recommended that government should strengthen financial laws that mandates financial institutions to give low interest rate loans to SMEs with little or no collateral. The government should accelerated development and upgrade of rural roads and rail network and other infrastructural facilities and review taxies in favour of local manufacturers especially the SMEs.

  • Description: In all higher education institutions across the world, the student retention and success is an issue of concern and a pressing one. Students invest heavily in their higher education, while institutions in turn, lose a considerable sum of money for each student that drops out due to dissatisfaction with institutional services. The purpose of this quantitative methods research study, employing a survey design, was to assess student satisfaction with institutional factors that influence student satisfaction in higher education. The research questions focused on student satisfaction factors namely; academic advising, academic support, teaching approaches, assessment techniques, learning facilities, student funding services, student accommodation and administrative services. The study used structured questionnaire, with Likert scale type of question items, to collect data from the respondents These were hand delivered to 650 students in four campuses of the selected university. SPSS was used for data analysis. Major findings revealed that the selected institutional factors significantly impacted on student satisfaction, and their decisions to stay within the institution. Based on the results of the study, a framework to assist the institution ensure that student are receiving the services that they need from the institution as early as possible, was proposed. The study provided therefore the useful data for institutions to use in their quality enhancement activities. The result of the study can be incorporated into enrolment management planning and the intervention strategies, to improve the success of students at the selected institution in Eastern Cape.

  • Description: The Department of Rural Development and Agrarian Reform maize cropping programme is one of the flagship projects that has been entrusted by the provincial government to tackle the social ills faced by the rural communities of the Eastern Cape Province. The programme is in line with a number of policies that strive to unlock the agricultural potential in inducing the much talked about radical economic transformation. This study was aimed at establishing if the outlay of the implementation processes and the outcomes of the maize cropping programme in Eastern Cape are sufficient to achieve the stated objectives. The study adopted a triangulation method to get comprehensive understanding of the programme and for accuracy and verification of the data collected. A pre-tested semistructured questionnaire was used to collect the demographics and socio-economic status of the respondents; technical skills and capabilities; implementation processes of the programme and the perceptions of the participants and key strategic role players in the maize cropping programme. A total of 120 respondents from DRDAR’s 2016/2017 financial year supported list and 9 key informants were sampled for the study. Furthermore, a gross margin analysis was used to establish the viability and the sustainability of the programme with and without DRDAR’s subsidies. For purposes of determining if there was any relation between the maize enterprise income and 13 independent variables, a multiple regression model was employed. The results of the study show that the programme is dominated by old and uneducated individuals with an average age of 60 years. The implementation processes are proving to be fairly progressed however, at a very limited scale. This includes provision of production inputs and mechanization services on time, formation of self-serving legal entities and unlocking the private sector investment. The gross margins generated from the programme have been observed to be non-viable and unsustainable. As a result, only 31% of the respondents were able to attain a gross margin equal or greater than the allocable costs of producing maize both under irrigation and dry land. The results of the regression model indicated that, only 5 of the 13 independent variables (household gender, marital status, years of participation, area planted and yield) were found to have a significant effect to the maize enterprise income. Overall, the DRDAR’s maize cropping programme has failed to meet its intended objectives. In addition, more than 70 percent of the programme participants produced for subsistence purposes and showed no desire to fully commercialise their operations.

  • Description: This study focussed on the synthesis and host properties of four different broad categories of potential host compounds, namely optically active and racemic TADDOL [(4R,5R)-α,α,α’,α’-tetraphenyl-1,3-dioxolane-4,5-dimethanol] and derivatives, TTFOL [(3R,4R)-2,2,5,5-tetraphenyltetrahydrofuran-3,4-diol], amino acid ester-derived compounds [(S)-4-(2-amino-3-hydroxy-3,3-diphenylpropyl)phenol], and compounds derived from xanthone [9-amino-9-phenylxanthene and 1,2-bis(9-phenyl-9H-xanthen-9-yl)hydrazine]. The potential hosts were recrystallized from a range of possible guest species and the resulting solids analysed by 1H-NMR spectroscopy. If inclusion was observed by this technique, the complexes were analysed further using single crystal X-ray techniques and thermal experiments where possible. Competition studies were carried out where these were deemed appropriate. Optically active and racemic TADDOLs were synthesized using L-(+) and DL-(±)-tartaric acid respectively. Two further derivatives were prepared whereby the hydroxyl groups were substituted for chlorine and azide in order to assess the effect of this change on the inclusion ability. Both the optically active and racemic TADDOLs displayed similar host abilities, complexing with guests with 1:1 host:guest ratios as determined through 1H-NMR spectroscopy. Competition experiments showed that both forms of TADDOL exhibited similar guest preferences for pyridine and the methylpyridine isomers. Pyridine however was preferred over 2-methylpyridine by optically active TADDOL while the racemic form preferred this methyl-substituted guest over pyridine. Thermal analysis studies showed, surprisingly, that the TADDOL complexes containing pyridine had higher relative thermal stabilities than those containing the methylpyridines, whether the host was optically active or not. The preference order of these hosts for these guests can, therefore, not be used as a predictor for the relative thermal stability of the complexes. TTFOL was found to include only ethanol, 2-methylpyridine and dioxane from the range of guest species used; the complex with dioxane did not produce X-ray quality crystals. The L-tyrosine derivative, (S)-4-(2-amino-3-hydroxy-3,3-diphenylpropyl)phenol, was an ineffective host incapable of including any of the guests used in these experiments. The two xanthone derivatives, 9-amino-9-phenylxanthene and 1,2-bis(9-phenyl-9H-xanthen-9-yl)hydrazine each formed complexes with one guest species (morpholine and DMF, respectively).

  • Description: The purpose of the study was born out of a perceived need to establish an assessment strategy framework for the fashion programme of one Eastern Cape comprehensive university. The study focused on one Eastern Cape comprehensive university. The programme, National Diploma: Fashion, is offered by the university at two campuses (120km apart). Although this programme is currently offered at both of the sites under the auspices of the university, disparity exists in many of the academic functions within the programme. The most challenging is assessment and the implications of a non-existent standard framework for assessment across both campuses. This research undertook to identify a framework that would best serve the Fashion programme of the researched university. Assessment in the context of this study referred to the process of both gathering evidence of student learning as well as assigning grades to that learning. The lack of an assessment framework affects the quality of assessment. Consistency in the assessment process across both campuses is important. At present assessment is not consistent as it is done independently on each campus. This lack of consistency could prove to favour students at the one campus while marginalizing students at the other campus and vice versa. Inconsistency arises from staff having no common assessment framework to refer to when assessment takes place. This study was a case study. Interviews were conducted with a sample of lecturers and students from both sites. A document analysis of relevant policies was done. The documents included the Higher Education Quality Committee document Criteria for Programme Accreditation, 2004, the South African Qualification Authority document Criteria and Guidelines for Assessment of NQF Registered Unit Standards and Qualifications, 2001, and the South African Qualification Authority document Guidelines for Integrated Assessment, 2005. University policy documents pertaining to assessment were also included in the research.The findings of this study lead to the conclusion that there is no clear assessment framework currently in place for the National Diploma: Fashion at one Eastern Cape comprehensive university. The assessment methods currently in use are not fully understood and comprehended by lecturers or students. The assessment types are limited with little or no variety as to how assessment is practiced. Although continuous assessment is advocated in the department, a lack of understanding by lecturers and students as to the true practice of continuous assessment is evident. Much of the assessment is done at the end of a teaching module, rather than embedded in the teaching module. This means that assessment is done of learning rather than for learning.

  • Description: The researcher attempted to investigate attitudes of community stakeholders towards stigmatization of people living with HIV/AIDS (PLWHA). This is because people living with HIV/AIDS are usually subjected to negative and positive attitudes in South African communities. The study made use of a case study as a specific research design which was explorative and descriptive. The study employed in-depth interviews, focus group discussions and secondary data sources to collect data. The study was a cross-sectional and adopted a non-probability sampling methodology, but specifically purposive technique. The study used 25 participants who consisted of 12 PLWHA, 5 nurses, and 8 selected community members. The data were analyzed through content thematic analysis. The findings that emanated from the study were: awareness of stigmatizing attitudes subjected to people living with HIV/AIDS (PLWHA); the attitudes displayed towards PLWHA, the drivers of stigma; the impact of stigma on PLWHA; PLWHA suffers immense psychosocial deficit; PLWHA face a state of abject poverty; PLWHA faces Psycho-emotional deficit; the secrecy surrounding the virus forms a fertile ground for infection; fear of contagion; stigma confounds chances of HIV/AIDS disclosure and issues of confidentiality. The study recommended that: the government should prioritize the PLWHA’s human rights; adoption of social media platforms to raise awareness and education of HIV/AIDS; collaboration between the Department of Health and the Department of Traditional affairs; invention of a youth-based psycho-emotional programme; and establishment of in-depth community supported interventions.

  • Description: Negative attitudes and stigmas against those diagnosed with mental illnesses have been found to prevail in modern society, despite the availability of effective treatments and attempts to educate people about mental health. Numerous studies have been conducted on the attitudes of various groups of people and communities towards mental illness. There is, however, limited research about student populations, particularly students registered for courses in the “allied health professions”. This study aimed to explore and describe the prevailing attitudes towards mental illness of a sample of the undergraduate Psychology student population (registered between 2nd and 4th year of study) within the Faculty of Health Sciences at a South African University. The procedure followed was an electronic intranet based survey, utilising the Community Attitudes to Mental Illness (CAMI) scale. The survey was accessed via the university’s student portal and links were sent via email to students to complete. A total of n=51 student responses were recorded and analysed. Data were quantitatively analysed using t-tests and Analyses of Variance (ANOVA). No statistically significant differences on the CAMI scales were found between the students in relation to the various student demographic variables such as age, gender, race or year level, and the CAMI findings. Overall, the sample of undergraduate Psychology students were shown to have favourable attitudes towards mental illness, which is potentially accounted for by their chosen field of study of Psychology. Education and knowledge about mental health were acknowledged as being most important in reducing stigma towards mental illness.

  • Description: The study focused on attitudes of professional nurses towards the dimensions of quality care. Quality care is the main focus of the Department of Health in the Republic of South Africa. The researcher believes that professional nurses form the backbone of the whole health care fraternity; hence they are central to the study of quality care dimensions. The aim of the study was to determine and describe the attitudes of professional nurses towards the dimensions of quality care in the community health centres of the KingSabatha Dalindyebo sub-district. A quantitative descriptive design was employed to meet the objectives of the study. The non-probability purposive sampling method was used to select participants to provide information on the attitudes of professional nurses towards the dimensions of quality care in the community health centres of the King Sabatha Dalindyebo sub-district, Eastern Cape. From the target of 84 professional nurses who were employed at the five community health centres of King Sabatha Dalindyebo sub-district of the O.R. Tambo District, Eastern Cape Province, 70 (83,3percent) professional nursesresponded to the questionnaires. A self-administered questionnaire written in simple English was used to collect data from the professional nurses regarding their attitudes towards dimensions of quality care. The researcher adhered to the ethical standards of nursing research as described by the Democratic Nursing Organisationof South Africa regarding anonymity, confidentiality, privacy and quality research, according to which the names of professional nurses were not recorded on the questionnaires. The data were analysed using the Statistical Package for the Social Sciences (SPSS) computer software. The distribution of the results has been presented in tables and a bar graph. The results of the study revealed that the professional nurses of these community health centres had positive attitudes towards the dimensions of quality care.

  • Description: The high sensitivities of modern radio telescopes will enable the detection of very faint astrophysical sources in the distant Universe. However, these high sensitivities also imply that calibration artefacts, which were below the noise for less sensitive instruments, will emerge above the noise and may limit the dynamic range capabilities of these instruments. Detecting faint emission will require detection thresholds close to the noise and this may cause some of the artefacts to be incorrectly detected as real emission. The current approach is to manually remove the artefacts, or set high detection thresholds in order to avoid them. The former will not be possible given the large quantities of data that these instruments will produce, and the latter results in very shallow and incomplete catalogues. This work uses the negative detection method developed by Serra et al. (2012) to distinguish artefacts from astrophysical emission in radio images. We also present a technique that automates the identification of sources subject to severe direction-dependent (DD) effects and thus allows them to be flagged for DD calibration. The negative detection approach is shown to provide high reliability and high completeness catalogues for simulated data, as well as a JVLA observation of the 3C147 field (Mitra et al., 2015). We also show that our technique correctly identifies sources that require DD calibration for datasets from the KAT-7, LOFAR, JVLA and GMRT instruments.

  • Description: This research explored the contribution made by shelters in the psychosocial empowerment of survivors of abuse in the contemporary South Africa. Abuse of women is increasing at an alarming rate and government is not able to handle the task single-handedly. The study utilized convergent mixed methods approach (Creswell, 2014) with qualitative and quantitative approaches used in tandem; but with the qualitative approach being more dominant, while quantitative approach was less dominant. For research designs, the qualitative approach used a case study design; while the quantitative method utilized a mini survey design. On the unit of analysis, 52 participants participated in the qualitative sample, with the following sample distribution: 30 participants (15 from each shelter) participated using in-depth interviews, 10 participants (5 from each shelter) constituted a focus group discussion with 12 participants (6 from each shelter) interviewed as key informants. The quantitative approach had a sample of 100 samples women who were victims of abuse complete a mini survey based on questionnaire interviews. The study identified many factors that prompted women to go and reside in shelters from physical abuse and sexual abuse usually perpetrated by women’s spouses taking the larger share. Other important drivers included economic and emotional abuse. This resonates with some of the tenets of the critical feminist theory that an offender’s victimization of another person is an expression of domination and control (Brownmiller and Russell, 1975 in Wilcox 2010). Furthermore, the United Nations recognizes that violence against women is a manifestation of historically unequal power relations between men and women, contributing from male domination and discrimination over women. The study also established various psychosocial services provided to survivors of abuse. Such services were important in order to strengthen survivors’ coping capacities, raise their confidence and reinforce their decision-making processes pertaining to their lives. Some of these psychosocial services provided include provision of accommodation, nutritional meals, therapeutic counselling, basic counselling sessions, group work sessions, access to skills development programmes, assistance in maneuvering the judicial system, job placements, parenting skills, access to education and provision of preschool for their children and information and referrals. This study also managed to unearth and identify the various institutional and operational challenges that beset the running of the two selected shelters in Pretoria. Acutely, shelters suffer funding challenges, with funding either being inadequate or having to take so long before it is availed and, therefore, almost affecting the day to day operations of the shelters. These shelters were also challenged by donor regulations, inadequate infrastructure and a continuous increase of survivors and children in their care. Furthermore, the study identified the shelters’ effectiveness to raise survivors’ hope for the future; boost their confidence; improve their social functioning; provide emotional and practical support; offer them the requisite accommodation and meals; and also provided them with different kinds of skills that made them financially independent. The research recommended that a decentralization of shelters to rural areas across all provinces and the nation at large would go a long way in ensuring that all survivors will get the assistance they need. As the rural-urban migration takes its toll, the abuse of women also continues to increase. Funding is the key to the success of every project, and, therefore, the provision of enough and consistent funding and a sustainable plan to the shelters will ensure the smoothness of the provision of services and reduce staff burnout, reduce high staff turnover, and increase the stability of trained personnel. The study also recommends the government to consider subsidizing the salaries for the staff working in shelters so that their salaries would be on par with their colleagues in other organizations. Government should also facilitate the institution of shelters for survivors of abuse as some men feel that the issue of abuse focuses on females and therefore men shy away from accessing the services of the shelters.

  • Description: We report on the conjugation of azide-derivatized gold nanoparticles (AuNPs) to alkyne moieties of ZnPc and InPc via azide-alkyne Huisgen cycloaddition reaction to form phthalocyanines-AuNPs (MPc-AuNPs) conjugates. The detailed structural characterizations of the composites were in good agreement with the expected results. The nonlinear absorption coefficients and other nonlinear optical limiting parameters were almost two times larger for the conjugates compared to free phthalocyanines. We established direct relationship between improved photophysical characterizations and enhanced nonlinear effects of reverse saturable absorption mechanisms favoured by excited triplet absorption of the phthalocyanines in the presence of AuNPs. The combination of InPc with AuNPs resulted in the lowest limiting intensity value of 0.06 J/cm2, hence the best performance in terms of optical limiting.

  • Description: The aim of this study is to design a rehabilitation centre for parolees which will address the issues pertaining to the re-integration of ex-inmates into society reducing the chances of recidivism. It challenges the current methods and strategies implemented in correctional facilities in South Africa, their insufficiencies in rehabilitating criminals and preparing them for a return to society. A new solution to this social problem of crime and recidivism Is explored through this architectural thesis. This is achieved through providing an infrastructure with consistent methodologies that cater for unit operations using boot-camp rehabilitation, healthcare and vocational training provided all as a collaborative effort with the correctional services, municipal healthcare services and private N.G.O’s. An adaptive approach both in the program and architecture contributes to the objective of meaningful social re-integration. The research methodology implemented is a qualitative investigation, through the Interpretation of contemporary situations, various site visits, Interpretative sketches of existing structures, Technical analysis from firms. Interpretive and case study research is also used, as a background to the research body.

  • Description: From introduction: We have a bumper issue, with eleven research papers and one letter to the editor. 2016 was a difficult year for academia in South Africa with highly disruptive protests. 2017 was mostly better from that point of view, though the protest movement has not completely gone away. This issue contains some papers that were submissions to special issues that were not ready in time and hence to some extent is a catch-up issue. In previous issues this year, 29(1), published in July, contained nine research papers, of which five were extended papers from the 2016 SAICSIT annual conference. There was also a special issue on ICT in Education published in October, 29(2), which had five research papers. Two papers from the ICT in Education special issue spilled over to this issue. Overall, we have published 25 research papers this year, compared with four in 2016, fourteen in 2015 and nineteen in 2014. Numbers are therefore looking healthy again; I hope the underlying causes of protest are addressed so we do not have to endure another year like 2016. In the remainder of this editorial, I give an update on the effects of indexing in Scopus, list papers in this issue and end with changes in the editorial team.

  • Description: My writing contains elements of hard-boiled detective fiction and crime writing. My stories, written in isiXhosa and English and a mixture of both, transplant these genres into a South African township setting where gang violence dominates and life is cheap. They are driven by uniquely South African characters, brutal crime scenes and fear-inspiring suspense, but none the less still full of humour. I want my work to entertain the reader while also looking realistically and critically at the problem of crime in our townships. I draw on influences of African and Latin American writers to create South African crime fiction in a realistic urban setting, with dynamic characters and sharp dialogue. , Le ngqokelela yamabali iqulathe amabali angobomi babantu abasezilokishini nabo bahlala ezilalini. Nangona umfundi angahle awafumanisa ehlekisa amanye elusizi, injongo yombhali asikukuhlekisa nakunyanzelisa imfundiso koko ikuzoba ubomi bababantu, bephila kwezi ndawo neengxaki abajongene nazo.

Bank Competition and Economic Growth: The Case of South Africa, Russia and China

  • Description: This study examined the relationship between bank competition and economic growth across South Africa, Russia and China. In this regard, the study conducted a comparative analysis which allowed for country differences and thus enhanced the provision of relevant policy guidance given how each of the country’s economic growth is reacting to changes in bank competition. To account for country differences, the study estimated a random coefficient panel (RCP) model using Swamy’s generalised least squares (GLS) estimators for the period 1999 – 2015. Across the three countries, bank competition and economic growth have been found to be positively related. In addition, bank competition has been found to be highly significant in influencing economic growth across the three countries. However, the extent of influence that bank competition has on economic growth differs in each country. Therefore, this study recommends that policies aimed at promoting competition in the banking sector of South Africa, Russia and China should be adopted in order to promote economic growth.

  • Description: Women representation in management positions is described as a fundamental human right and an important means of fair democratic representation. This study intended to investigate the factors determining women upward mobility and their promotion to management positions. Included as variables were traditional gender roles, access to education and lack of mentoring and role models. The study followed the qualitative approach using snowball sampling and conducting semi structured interviews with ten Controlling Officers from different ministries and department of the Malawi Public Service to find out whether the variables under investigation indeed affect women upward mobility. Empirical evidence shows that traditional gender roles e.g. being mothers affect women upward mobility. Similarly, limited access to education is another factor that limits women access to managerial positions. Lack of mentoring and role models, especially where there are already few women at the top also affects women’s upward mobility. The study recommended that Malawi government should help women get scholarships that provide for their children. Furthermore, the government should provide flexible working hours especially for mothers. Women themselves should meet for a cup of tea where they can empower each other on the most important aspects of their job as chief executives; that is delivering a speech, making presentations and forming networks.

Being young, black, woman academics on an Accelerated Development Programme in an Historically White University in South Africa: a narrative analysis

  • Description: The national program for the development of next and new generation academic professionals (NGAP) aims to help Universities to diversify their academic teaching staff to be more reflective of the national demographics of the country. Through NGAP and policies of redress, a Historically White University would predictably introduce young black women into their academic teaching staff. This is a category of the population who would have been most affected by the exclusionary hiring policies that would have generally been in use in historically white universities before 1995, the year following the first democratic elections. The selection of staff according to criteria that has historically been used to exclude them is a policy which is widely considered to be a useful and necessary way to institute redress. While this half thesis does not disagree with this social and moral imperative, I find interest in the lack of focus on the emotional, psychological, spiritual and otherwise personal toll of the implementation of such a policy on those who are introduced through it and related policies. I believe there is a need to problematise the highly normative environments in which staff (to benefit from redress) are required to function. This half thesis examines the narrated experiences of three such staff members at Rhodes University with specific interest in their everyday experiences in an institution which has historically been tailored for (and in many cases is still run by) white, older male academics. The thesis indicates that the emotional and psychological effects and 'taxes' of being on an accelerated development programme may be worth noting and appreciating in order to think about the retention of black woman academics. The findings show that the complexity of younger black women's experiences within historically white universities such as Rhodes University requires equally complex and multifaceted strategies and programmes. These programmes should not only support these academics but also undermine existing exclusionary institutional cultures in order to facilitate true, deep transformational practice in historically white universities such as Rhodes University.
