- 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: Several aza boron-pyridyl-isoindoline analogues are synthesized through a facile and scale-up two step reaction using 1,2-naphthalenedicarbonitrile as a starting material. These analogues show broad envelopes of intense vibrational bands in the absorption spectra with moderate fluorescence quantum yields in solution and the solid-state. An analysis of the structure–property relationships is described based on X-ray crystallography, optical spectroscopy, and theoretical calculations.

- 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: 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.

- Description: Marine ranching has been identified as an alternative to traditional aquacultural rearing and growing organisms for consumption. In the Eastern Cape, abalone ranching is a new and experimental industry. The aims of the research were to: first develop a GIS model to assist management in site selection for abalone seeding; and secondly to develop and standardize the sampling methodology in order to ground truth the sites, and assist in the monitoring and habitat identification of abalone. The GIS model developed in Chapter 3 was created using an unsupervised classification and fuzzy logic approach. Both vector and raster datasets were utilized to represent 7 different layers. Predominantly satellite imagery was used to classify the different substrate groups according to pixel colour signatures. The basic process was to apply a fuzzy rule set (membership) to rasters which gave an output raster (Fuzzification). The membership output rasters were overlaid which creates a single model output. It was found that model accuracy increased significantly as more layers were overlaid, due to the high variability within each of the individual layers. Model ground-truthing showed a strong and significant correlation (r2 = 0.91; p < 0.001) between the model outputs and actual site suitability based on in situ evaluation. Chapter 4 describes the investigation towards the optimal sampling methods for abalone ranching habitat assessments. Both destructive sampling methods and imagery methods were considered as methods of data collection. The study also evaluated whether quadrat and transects were going to be suitable methods to assess sites, and what size or length respectively they should be to collect the appropriate data. Transect length showed great variation according to the factor assessed. A transect of 15 metres was found to be optimal. Abalone counts showed no significant (p = 0.1) change in the Coefficent of Variance (CV) for transect lengths greater than 15m, and had a mean of 0.2 abalone per metre. Quadrat size showed a significant difference in functional group richness between quadrat sizes of 0.0625m2, and 0.25m2 but no difference between 0.25m2 and 1m2 quadrats for both scape and photographic quadrats. It was also found that between 5 and 10 replicates (p = 0.08) represents the functional groups appropriately using quadrats and that a 0.25m2 quadrat is most suitable for sampling. Chapter 5 describes the benthic community structure of Cape Recife shallow water reefs. Using the standardized methodology previously mentioned, 45 sites were assessed to identify the community structure. These sites were grouped into 5 different groups influenced by depth and substrate, as well as functional group composition according to a Wards classification. The community structure showed that depth and substrate play a significant role (p < 0.05) in the community type. There is also a significant relationship (p < 0.05) between complexity, rugosity, abalone presence and substrate. During this study the basic protocols for site selection and benthic community monitoring have been developed to support the abalone ranching initiative in the Cape Recife area. It has also provided a baseline of the benthic community in the ranching concession area which will be used as a benchmark for future monitoring efforts. The site selection, sampling, and monitoring methods developed during the course of this work have now been rolled out as Standard Operating Procedures for the ranching programme in this area.

Quadrat size showed a significant difference in functional group richness between quadrat sizes of 0.0625m2, and 0.25m2 but no difference between 0.25m2 and 1m2 quadrats for both scape and photographic quadrats. It was also found that between 5 and 10 replicates (p = 0.08) represents the functional groups appropriately using quadrats and that a 0.25m2 quadrat is most suitable for sampling. Chapter 5 describes the benthic community structure of Cape Recife shallow water reefs. Using the standardized methodology previously mentioned, 45 sites were assessed to identify the community structure. These sites were grouped into 5 different groups influenced by depth and substrate, as well as functional group composition according to a Wards classification. The community structure showed that depth and substrate play a significant role (p < 0.05) in the community type. There is also a significant relationship (p < 0.05) between complexity, rugosity, abalone presence and substrate. During this study the basic protocols for site selection and benthic community monitoring have been developed to support the abalone ranching initiative in the Cape Recife area. It has also provided a baseline of the benthic community in the ranching concession area which will be used as a benchmark for future monitoring efforts. The site selection, sampling, and monitoring methods developed during the course of this work have now been rolled out as Standard Operating Procedures for the ranching programme in this area.

- Description: Pregnancy is a normal physiological process for the majority of women. These women, their families and significant others normally expect a successful period of pregnancy, labour, delivery and arrival of a normal and healthy baby. However, some of these pregnant women may develop Gestational Diabetes Mellitus (GDM) during this period and if not managed properly, the mother and the foetus in utero are affected in a negative way: there is a likelihood of the mother and baby developing Type 2 Diabetes in the future and also, other risks such as preterm labour, and foetal macrosomia. In order to prevent such occurrences, I set out to develop a best practice guideline for the nursing management of GDM in military health institutions in Ghana in order to help enhance nursing care. The design for this research was qualitative, explorative, descriptive and contextual in nature. The research is organised in three phases: Phase one deals with the data analysis and discussion of the interviews with professional nurses and midwives and women with a history of GDM. The data collected from the interviews were transcribed, analysed and extracted with Tesch’s eight steps of coding used for the coding. The services of an independent coder were employed to assist with the coding process which led to the formulation of key themes. Semi-structured individual interviews provided a means of exploring the perceptions of professional nurses and midwives on the nursing management of GDM: in addition, women with a history of GDM were interviewed so as to elicit their views on the management they had experienced from professional nurses and midwives before and after being diagnosed with GDM. The trustworthiness of the study was ensured by conforming to Lincoln and Guba’s framework of credibility, transferability, dependability, confirmability and authenticity. An independent coder assisted with the coding process. Phase two deals with the Integrative literature review of available evidence-based clinical practice guidelines for the nursing management of GDM. Evidence-based clinical practice guidelines were searched and appraised with assistance from an independent appraiser and themes were then formulated. In Phase three, the themes from Phase one and Phase two were integrated for the development of a draft best practice guideline for the nursing management of GDM in military health institutions in Ghana. The draft guideline was given to an expert panel of reviewers for their comments and recommendations. These were considered in the development of the final best practice guideline for the nursing management of GDM.

- Description: Small businesses of which the majority are female-owned are the backbone of many economies across the globe. Despite the increasingly important role of female-owned small businesses to economic development and poverty alleviation, the growth of female-owned businesses in Uganda remains a major concern. The purpose of this study, therefore, was twofold – to identify business growth challenges of female small business entrepreneurs in Uganda and also to identify the strategies for overcoming these small business growth challenges to add to existing theory within the small business management field. The study followed a qualitative research with an exploratory descriptive case study design approach. A comprehensive international and national literature on female entrepreneurship, the Ugandan business environment, small business growth challenges in Uganda, and global best practice strategies for stimulating small business growth was conducted. Primary data were collected using face-to-face and telephonic interviews with semi-structured interview guides. Twelve (three female small business entrepreneurs and nine small business support specialists) participants were selected using purposive, theoretical, and expert sampling methods. The biographical profiles of the participants interviewed during the study were presented as case studies. Firstly, the biographical profiles of the three Ugandan small businesses (supermarket, restaurant and hairdressing salon) and the female entrepreneurs were presented. Secondly, the biographical profiles of the nine small business support institutions (two governmental, two funding, two training, one export promotion) and two business associations, as well as the profile of the small business support specialists were presented. Based on the content analysis of the qualitative interviews with the three female small business entrepreneurs, their current business status revealed that the female entrepreneurs have growth aspirations and aligned their goals towards it, but did not have strategies in place to effect business growth. Further still, based on the empirical results of the female small business participants, eight main challenges were identified as: lack of adequate business support and business skills training; demanding and costly business registration and trading license processes; high business taxation; access to finance; inadequate road infrastructure; family-related issues and cultural taboos. These participants also suggested some solutions to overcome these challenges. The small business support specialist participants either confirmed the challenges that specifically females experience or confirmed that they are perceived and not real challenges, or that it is not female-specific but generic to all small businesses. The study further established what female small business participants regard as possible strategies to the challenges experienced, while the small business support specialist participants could indicate which strategies have already been implemented and also suggest further strategies. It was concluded that although many of the challenges could apply to all small businesses, this study found that cultural taboos and family-related issues are a real challenge for female small business entrepreneurs. As seen in this study, these two main challenges can further influence some of the other challenges. It can influence whether qualifying for access to funding, having extra funding to pay for registration, licensing and tax, what the business is allowed to sell, and even the novelty of a female owing a business, never mind wishing to grow their businesses. Although some challenges such as discrimination against female entrepreneurs regarding access to small business support or funding is perceived, there are real infrastructure challenges such as rural road conditions, access to electricity and ICT. Several strategies are already in place in Uganda to assist all small businesses with business growth, but not necessarily just assisting female small business entrepreneurs. However, many of these strategies are work-in-progress and have not yet had the desired end result. This study made a contribution to knowledge by indicating that government-, skills training-, financial- and export promotion institutions, as well as business associations together with influential community members, can contribute significantly to the implementation of several strategies to promote female small business growth. In addition, the chapter on best practices of global developed – and developing countries provided insight into making well-informed practical recommendations that Uganda can implement to assist small businesses to grow and in particular females small businesses. These global best practice strategies for the growth of SMMEs as applied within the seven selected seven countries were elaborated on in detail with a clear indication of the responsible bodies in Uganda that can affect these strategies. The emphasis was on suggesting strategies that can be practically executed with relative ease in Uganda as a developing country. This study concludes that it remains the responsibility of female small business entrepreneurs to make the effort to grow their small businesses and turn their business visions into reality. They should write a business plan, search for and approach small business support institutions for assistance and engage in an extensive networking drive to grow their customer market and to search for opportunities to grow their business such as private-public sector partnerships or expansion into the international market. Awareness is not just the responsibility of the several small business support institutions in Uganda, but female small business entrepreneurs should actively scrutinise media reports in newspapers, the radio and television to obtain information regarding business support opportunities.
