- Description: Fe3O4 magnetic nanoparticles (MNPs) and glutathione (GSH) capped CdSe@ZnS quantum dots (QDs) were separately coordinated to indium octacarboxy phthalocyanine (InPc(COOH)8) to form ClInPc(COOH)8–MNPs and ClInPc(COOH)8–GSH–CdSe@ZnS, respectively. The photophysical parameters (triplet state and fluorescence quantum yields and lifetimes) were determined for the conjugates. The triplet quantum yields increased from ΦT = 0.49 for InPc(COOH)8 alone to ΦT = 0.61 and 0.56 for InPc(COOH)8 in the conjugates: ClInPc(COOH)8–MNPs and ClInPc(COOH)8–GSH–CdSe@ZnS, respectively. The lifetimes also became longer for the conjugates compared to Pc alone.

- Description: In the competitive knowledge economy of today it is talented employees who ensure a competitive advantage for their company above their competitors. Voluntary employee turnover is said to have a number of negative consequences for employers, such as recruitment, selection and training costs, as well as lowered morale in the case of employees who stay behind. Companies and countries such as South Africa have to become globally competitive through talented and dedicated employees. Companies should therefore place more focus on the retention and grooming of their internal talent since a “war on talent” is being waged between companies for the best talent. With the looming shortage of talent globally it becomes more important for organisations in general and the petrochemical sector in particular to understand why talented and dedicated employees voluntarily leave their organisations. With such insight at their disposal, people managers are able to devise appropriate strategies to retain talent for the competitive benefit of their own organisations. The principal objective of this research study was to improve employee retention by investigating the influence of career-pathing (career development practices) and other selected critical success factors on employee retention. The study considered how employee retention (the dependent variable) is influenced by affective organisational commitment, career-pathing, growth need satisfaction, job commitment, affective professional commitment, continuance professional commitment and normative professional commitment (the independent variables). The sample who participated in this study consisted of one hundred and one (101) out of a possible total of two hundred and eleven (211) respondents from the selected South African petrochemical organisation. The empirical results reveal that affective organisational commitment and career-pathing are significantly related to employee retention, while all the other variables tested are not significantly related to employee retention.

- Description: Municipal solid waste management is gradually becoming a major challenge that is confronting governments in all spheres. This can be attributed to urbanisation and startling population escalation. Each and every member in a community is a contributor to this dilemma and a generator of waste. The essence of this study is to investigate whether the utilisation of education programmes can assist to improve how communities handle and dispose their household waste and its contribution to the effectiveness of the integrated solid waste management system for the New Brighton Township in the Nelson Mandela Bay Municipality. A theoretical framework is developed using the systems theory in trying to address the challenge. The study used the qualitative research method. Data were gathered using questionnaires and face-to face interviews. The empirical survey was employed for the purposes of the study and the interpretation of the research findings were analysed and described. As a metropolitan municipality, it is envisaged that this research will assist the NMBM, to identify how to manage solid waste efficiently and effectively and thus enhancing service delivery that will ensure communities of their well-being and dignity. Various recommendations are presented, based on the findings of the study. It is hoped that these recommendations If are adopted, the NMBM will be able to deal more effectively and efficiently with the challenges that the NMBM is faced with in dealing with waste management issues thereby enabling the NMBM to deliver the most basic need to the communities of the New Brighton Townships.

- Description: In this study the survey was conducted at an automotive component manufacturer to examine the theory about what influence knowledge sharing within an organisation. The evaluation would assist in improving knowledge sharing by indicating which strategies are appropriate for management to enhance knowledge sharing within the organisation. Organisations lose expertise and knowledge because of employee movements and old employees that have retired. The literature review was done as a guidance to test what influences employees to share their knowledge. Based on the survey and literature study that was conducted it was concluded that by making resources available, employee personality traits, giving employee recognition, encouraging better social environment within the organisation and job design that would make it easy for knowledge to flow amongst employees that will elevate knowledge sharing within the organisation. The conclusion and recommendation were formulated for management at the end of the study.

- Description: This dissertation is based on the results of a study that used a working memory (WM) adaptive computer programme known as Jungle Memory to determine whether training WM would have a positive impact on learners with reading difficulties, which would ultimately lead to an improvement in their overall academic performance. A pragmatic paradigm has been used, involving a mixed methodology that allowed for a postpositivistic as well as a constructive approach. The first section of the investigation involved the quantitative component, where specific variables (performance levels of the sample of learners) were determined. Thereafter, empirical measures were used to determine if these specific variables increased once the WM intervention programme had been completed. Concurrently, in the qualitative component, the sample group (namely the teachers working with these learners) provided qualitative information to verify if any changes in the participants were observed after the intervention. The participants included 30 boys who attend an ex Model C School in the Eastern Cape where I teach, all of whom had been identified as experiencing various reading difficulties and were receiving remedial assistance. The boys were placed into three groups according to specific criteria: Group A had all been diagnosed as having ADHD and were being treated pharmaceutically for the disorder; Group B all had significant ADHD symptoms but were not receiving any pharmaceutical assistance to alleviate these symptoms; and Group C displayed no significant ADHD symptoms. Five boys from each subgroup formed the Experimental group and the other five formed the Control group in each stratum. The participants' class-based teachers involved in the qualitative component of the study provided information-rich data regarding any notable progress made by each participant. Each participant took part in a battery of pre-assessment tests to determine their general level of academic performance. These assessments included the following well-known standardised tests in South Africa: the Young Group Reading Test, the Essi Reading Test, the Essi Spelling Test and the Vassi Mathematics Proficiency Test. The participants from all three Experimental Groups then took part in the eight week intervention programme, Jungle Memory, while the Control groups continued with their regular remedial programme. At the end of the eight weeks, all the participants were re-assessed using the same standardised tests.The findings from this study revealed that the participants from all three strata of the Experimental group showed significant improvements in the quantitative postassessment results and twelve of the fifteen also showed significant improvements in the comments made by the teachers in the qualitative component. The majority of the participants from the Control groups however, made very little progress in both components, and these small improvements were probably due to other variables such as maturity, incidental WM improvements through observing their peers, or familiarity with the tests.

- Description: The value of employees has been established as the best asset a company can have and managers/leaders plays an important role in optimising the value addition of the employee. Retaining employees and attracting them is a challenge due to skill shortages and staff turnover. The costs of staff turnover include but are not limited to recruiting, testing, selecting, training the new staff member, and mandatory overtime due to staff shortages. The indirect costs associated with such turnover are caused by the loss of valued employees, the stress of additional workloads, the loss of the social relationship and the tension of integrating new employees into the team. The objective of the study was to identify the factors that increase voluntary and involuntary turnover intent in the selected purchasing department. These factors were manager /leader’s influence, stress and satisfaction with quality of work life on turnover intent. Convenience sampling was used to distribute sixty-four questionnaires in three departments of the selected firm, namely production purchasing, general purchasing and projects. Only fifty usable questionnaires were received. The results from the descriptive statistics revealed that the participants were generally not happy with manager relations in the firm. The results however showed that this does not motivate employees to stay or leave the firm. The statistics showed that bullying is evident in the selected firm, however the mean score does not reflect high levels thereof. The Pearson correlations show a significantly positive relationship between bullying and employees leaving. The participants generally work in a stressful environment and this affected some employees negatively however Pearson’s correlations showed that work stress is not significantly related to intent to leave.

- Description: Results from recent international assessments showed that the performance of South African learners in these international benchmarking assessments remained at rock bottom of the study rankings. These results not only paint a dim picture of the ability, work ethic and attitude of learners in the South African schooling system, but it also calls into question the performance intent of educators. This study becomes very important against the background that learners being taught in South African classrooms are increasingly facing stiffer competition in the market place due to the phenomenon of globalisation. The perception of the international community pertaining to the quality of teaching and learning in South African schools is bound to impact significantly on the keenness of foreign countries to engage with South Africa on a meaningful scale. The primary objective of the study is to improve the performance intent of school-based educators in the Uitenhage Education District. More specifically, the study investigates the relationship between the performance intent of educators (the dependent variable) and motivation, commitment to profession, commitment to the leader, community engagement and professional development (the independent variables). Given the constraint of distance, the sample was limited to schools in the Uitenhage Education District, and for this reason, convenience sampling was used for purposes of this study. Three hundred and sixty questionnaires were issued, of which 316 were returned (a response rate of 88%). The empirical results revealed all the independent variables impact significantly on the performance intent of educators at public schools in the Uitenhage Education District. The research findings cannot be generalised to all schools in the province because the sampled schools compose only a relatively small portion of all schools in the Eastern Cape Province. Recommendations for future research are also provided.

- Description: The performance management system has become a vital process of retaining skilled employees, helping to improve communication between the employees and management, providing feedback to employees and clear understanding of job expectation. A performance management system assists the firm to identify the ways to improve individual and firm performance and provides the opportunity for discussion about individual career direction and growth within the firm. It provides the opportunity to set employee targets linked to the departmental targets. The performance management system is the catalyst for firms to become globally competitive and be able to meet targets. Over the years the firm has introduced a performance management system to help employees to achieve their targets, which will result in the company meeting its own objectives. The study focused on the factors that affect the performance management system. The objective of the research was to improve the performance management system of the firm. The study was conducted to assess the effect of the following independent variables on the improvement of the performance management system: leadership style, training, organisational culture, reward system and organisational communication. The sample consisted of only the employees of the firm selected for the study. One hundred and fifty (150) questionnaires were distributed, but only seventy-six (76) respondents (response rate = 50.7 percent) participated in the final study. The empirical results revealed that the three independent variables play a very important role in improving a performance management system. These three variables are organisational culture, training, and reward system. Implementing the recommendations that came from these results will go a long way to making sure that the firm will improve its performance management system.

- Description: This thesis is concerned with transnational literature and writers of the Middle Eastern and South Asian diasporas. It argues that the diasporic position of the authors enables their roles as comprador subjects. The thesis maintains that the figure of the comprador is always acted upon by its ontological predisposition, so that diasporic positionality often involves a single subject which straddles and speaks from two or more different subject positions. Comprador authors can be said to be co-opted by Western metropolitan publishing companies who stand to benefit by marketing the apparent marginality of the homelands about which these authors write. The thesis therefore proceeds from the notion that such a diasporic position is the paradoxical condition of the transnational subject or writer. I submit that there is, to some degree, a questionable element in the common political and cultural suggestions that emerge upon closer evaluation of diasporic literature.

However, it is this difference, the implied otherness or marginality of the outsider within, which I argue is sometimes used by diasporic writers as a way of articulating with ‘authenticity’ the cultures and politics of their erstwhile localities. This thesis is concerned, therefore, with the representation of ‘the East’ in four novels by diasporic, specifically comprador writers, namely Salman Rushdie’s Midnight’s Children, Hanif Kureishi’s The Buddha of Suburbia, and Khaled Hosseini’s The Kite Runner and A Thousand Splendid Suns. I suggest that the ‘third-world’ and transnational literature can also be a selling point for the transnational subject, whose representations may at times pander to preconceived ideas about ‘the Orient’ and its people. As an illustration of this double-bind, I offer a close reading of all the novels to suggest that on the one hand, the comprador author writes within the paradigm of the ‘writing back’ movement, as a counter-discourse to the Orientalist representations of the homeland. However, the corollary is that such an attempt to ‘write back’, in a sense, re-inscribes the very discourse it wishes to subvert, especially because the literature is aimed at a ‘Western’ audience. Moreover, the template of the comprador could be used to explain how a transnational post-9/11 text from an Afghan-American, for instance, may be put to the service of the imperial machine, and read, therefore, as a supporting document to the U.S. policy on Afghanistan.

- Description: This thesis is concerned with transnational literature and writers of the Middle Eastern and South Asian diasporas. It argues that the diasporic position of the authors enables their roles as comprador subjects. The thesis maintains that the figure of the comprador is always acted upon by its ontological predisposition, so that diasporic positionality often involves a single subject which straddles and speaks from two or more different subject positions. Comprador authors can be said to be co-opted by Western metropolitan publishing companies who stand to benefit by marketing the apparent marginality of the homelands about which these authors write. The thesis therefore proceeds from the notion that such a diasporic position is the paradoxical condition of the transnational subject or writer. I submit that there is, to some degree, a questionable element in the common political and cultural suggestions that emerge upon closer evaluation of diasporic literature. Indeed, a charge of complicity has been levelled against authors who write, apparently, to service two distinct entities – the wish to speak on behalf of a minority collective, as well as the imperial ‘centre’ which is the intended interlocutor of the comprador author. However, it is this difference, the implied otherness or marginality of the outsider within, which I argue is sometimes used by diasporic writers as a way of articulating with ‘authenticity’ the cultures and politics of their erstwhile localities. This thesis is concerned, therefore, with the representation of ‘the East’ in four novels by diasporic, specifically comprador writers, namely Salman Rushdie’s Midnight’s Children, Hanif Kureishi’s The Buddha of Suburbia, and Khaled Hosseini’s The Kite Runner and A Thousand Splendid Suns.

- Description: The 90-KDa heat shock protein (Hsp90) is part of the molecular chaperone family, and as such it is involved in the regulation of protein homeostasis within cells. Specifically, Hsp90 aids in the folding of nascent proteins and re-folding of denatured proteins. It also plays an important role in the prevention of protein aggregation. Hsp90’s functionality is attributed to its several staged, multi-conformational ATPase cycle, in which associated client proteins are bound and released. Hsp90 is known to be associated with a wide array of client proteins, some of which are thought to be involved in multiple oncogenic processes. Indeed Hsp90 is known to be directly involved in perpetuating the stability and function of multiple mutated, chimeric and over-expressed signalling proteins that are known to promote the growth and survival of cancer cells. Hsp90 inhibitors are thus thought to be promising therapeutic agents for cancer treatment. A lack of a 3D structure of human Hsp90 however has restricted Hsp90 inhibitor development in large to in vivo investigations. This study, aims to investigate and calculate hypothetical homology models of the full human Hsp90 protein, and to probe these structural models for novel drug target sites using several in silico techniques. A multi-template homology modelling methodology was developed and in conjunction with protein-protein docking techniques, two functionally important human Hsp90 structural models were calculated; the nucleotide free “v-like” open and nucleotide bound closed conformations. Based on the conservation of ligand binding, virtual screening experiments conducted on both models using 316 natural compounds indigenous to South Africa, revealed three novel putative target sites. Two binding pockets in close association with important Hsp90-Hop interaction residues and a single binding pocket on the dimerization interface in the C-terminal domain. Targeted molecular docking experiments at these sites revealed two compounds (721395-11-5 and 264624-39-7) as putative inhibitors, both showing strong binding affinities for at least one of the three investigated target sites. Furthermore both compounds were found to only violate one Lipinski’s rules, suggesting their potential as candidates for further drug development. The combined work described here provides a putative platform for the development of next generation inhibitors of human Hsp90.

- Description: The cyanobacterially synthesized non-canonical amino acid β-N-methylamino-ʟ-alanine (BMAA) has been proposed to be a causative agent in the development of sporadic neurodegenerative diseases. This neurotoxin bioaccumulates and biomagnifies with increasing trophic levels in ecosystems by associating with proteins. It has been suggested that these associations with host proteins also serve as a reservoir from where BMAA is slowly released with normal protein catabolism, resulting in a continuous low level exposure. However, the nature of these associations remains poorly defined. The widely accepted hypothesis regarding the nature of these associations is that BMAA associates with proteins through primary incorporation into proteins with specific replacement of serine. In addition to excitotoxicity, BMAA misincorporation has been proposed as a potential mechanism of toxicity because of its link to protein tangle diseases. Interactions between BMAA and proteins that are not the result of misincorporation, have also been observed. However, the nature of these non-primary associations has not been investigated. This study focussed on establishing whether BMAA is misincorporated into host proteins with consequent toxicity, and on elucidating the nature of the BMAA-protein associations not linked to primary incorporation. In comparative studies between BMAA and canavanine, an arginine analogue known to misincorporate, exposure to BMAA did not result in any toxicity in prokaryotes or in an undifferentiated eukaryotic mammalian cell line, in contrast to what was observed upon canavanine exposure. Differentiation of the cell line with nerve growth factor to express glutamate receptors resulted in marked toxicity upon BMAA exposure, highlighting excitoxicity as the main mechanism of BMAA toxicity. Furthermore, it was demonstrated that BMAA interacts with free amino acids and proteins in the absence of de novo protein synthesis, causing enzyme inhibition and protein misfolding. It was concluded that BMAA does not interact with proteins through primary incorporation and that the observed associations are the result of an interaction between BMAA and amino acid side chains to form covalent bonds.

- Description: The Benguela Cold Current system, located in the south-eastern Atlantic, features cold sea surface temperatures, bounded to the north and south by tropical currents (the Angola and Agulhas Currents, respectively) and a perennial upwelling cell off central Namibia that divides the region into two sub-systems with different characteristics (Shannon 1985; Hutchings et al. 2009). The colder sea surface temperatures of the Benguela Current have been considered an important biogeographic barrier, isolating tropical and warm-temperate fauna of the Atlantic and Indo-Pacific Oceans (Avise 2000; Floeter et al. 2008). However, recent studies revealed that other oceanographic features, such as the perennial upwelling cell, may also play an important role in shaping the population structure of warm temperate fish populations within the Benguela system, as complete disruption of gene flow was documented both in Lichia amia (Linnaeus, 1758) and Atractoscion aequidens (Cuvier, 1830) (Henriques et al. 2012, 2014). Little is known, however, regarding the influence of the Benguela system on genetic population connectivity of cold-water-tolerant species.

- Description: South Africa has witnessed series of social unrest, many of which ended in violence by very poor communities who allege poor delivery of basic goods and services. The majority of South African citizens are poor and pervasive inequality exists between men and women and between black and white peoples of the country. The poverty alleviation strategies inequalities and the consequences of poverty amongst women in rural areas (Ozoemena, 2010). Cacadu District municipality has done a study analysis on poverty alleviation in 2009-2010 together with the Baviaans municipality to verify which areas was the most poorest in Baviaans municipality. The findings came as Vondeling and Riertbron which was the poorest area. The focus was on tourism side because Baviaans is the tourist area.Rietbron and Vondeling is part of Baviaans Arts and craft program that was previously funded by DEDEAT R500, 00 but only benefited after incorporated to Baviaans municipality as they were previously managed by Cacadu District Municipality before and the municipality decided to invest in this areas. The funding for DEDEAT was utilized for trainings, starting material and equipment’s and building of the Baviaanskoof Craft Shop for two projects which is Vondeling and Steytlerville and Rietbron did not benefit at that time. This study focuses on the income generating projects in Baviaans municipality with the view to describe the experiences of individuals who participate in these income generating projects. The objective of this study was to evaluate the contribution of income generating projects in addressing poverty alleviation. Steytlerville projects is using waste materials like old newspaper, raw material, broken cups to do jewellery .Vondeling and Rietbron project is an angel factory producing beaded wire angels by using materials locally produced merino wool, wire wool, beads and local products such as ostrich feathers .This study is based on a case study which gives a description of poverty and reflects an involvement process of beneficiaries or communities in an income generating project and how it is impacting on their livelihoods. Qualitative and quantitative methodology were used. According to Neuman (2000: 30), the quantitative data methods refer to the collection of data using numbers, counts and measures of things and qualitative research basically involves the use of words, pictures description and narratives”. Data was collected for interviews. In order to collect accurate information, an interview was conducted based on the author’s research questions. Research was conducted in different areas like Steytlerville, Vondeling and Rietbron. A questionnaire was used as a form of data collection for the three projects. These interviews were conducted formally in a focus group composed of the projects members. In Steytlerville they were 5 members, Vondeling 7 members and Rietbron10 members which make a sample of 22 members. These projects have two craft shop where they sell their product which is Willomore craft shop and Baviaanskloof craft shop. The craft shop has been established to create an outlet by which locally sustainably made craft can be displayed and sold. The craft shop has been developed in such a way that is a real life example of a green building and business .The craft shop is an example of how to be environmentally friendly and utilise nature in such a way that it is sustainable and does not destroy it. The research findings suggested that in certain instances, Baviaans Craft project has been successful in generating income for members. The market for these crafters is mainly tourists. From this research it came out clear that some of the project members were able to acquire skills which help them to find employment in well-established craft business. Despite the successful of Baviaans Craft project, the project members were somewhat constrained in managing and running the business. For example with response for special markets, they had to make use of external skills i.e. someone who made contacts with the export market and there after divide the profits amongst members. The project members were not adequately empowered in management skills.

- Description: Given the importance of family businesses with regard to the economic growth of South Africa, and the fact that their high failure rates have a negative influence on the country’s economy, this study focused on ineffective leadership among family businesses and the influence thereof on business performance. People’s perceptions of leadership are changing, and an ethical, people-centred, character-orientated approach to leadership may be what businesses require. In addition, innovation and employee well-being are being given high priority, and leadership that is ethical and caring is of great importance. The primary objective of this study was twofold, firstly to establish the levels of Ethical, Authentic, Participative and Servant leadership displayed by family business owners and employees in the Eastern Cape, and secondly to establish the influence on the Perceived business performance of the family business of displaying these styles. Poor leadership was identified as a major challenge that family businesses are faced with, and a challenge that contributes to their high failure rate. The literature dealt with the nature and importance of leadership, and both traditional and contemporary leadership styles were elaborated on. The traditional leadership styles identified were autocratic, laissez-faire, transactional, transformational and participative leadership, while the contemporary styles identified and discussed were ethical, authentic and servant leadership. From the literature it was evident that a more ethical, people-centred, character-orientated approach to leadership may be what businesses require to be successful today. The literature highlighted Ethical, Authentic, Participative, and Servant leadership as the more character-orientated leadership styles that positively influence the performance of any business, including family businesses. These leadership styles formed the main focus of this study. In this study a quantitative research design was adopted and a descriptive study of a cross-sectional nature was undertaken. A convenience sampling technique was used owing to the inaccessibility of a family business database. The sample size in this study consisted of 250 small family businesses. A survey was undertaken and a structured, self-administered questionnaire was used to gather the necessary data. The measuring instrument was developed by sourcing items from several existing studies. Family business owners and employees working in the family business were approached by fieldworkers and asked to participate in the study. In total, 266 questionnaires were usable, 133 from family business owners and 133 from family business employees. An effective response rate of 53.20 percent was achieved. The validity and reliability of the measuring instrument were confirmed by means of an exploratory factor analysis (EFA) and by the calculation of Cronbach’s alpha coefficients. Descriptive statistics were calculated in order to summarise the sample data, while t-tests were used to determine whether the differences in mean scores returned by the family business owner and employee sample groups for the leadership styles under investigation, were significantly different from each other. Pearson’s product moment correlations were used to assess the associations between the variables under investigation. A multiple regression analysis (MRA) was used to assess the relationships between the independent variables and the dependent variable Perceived business performance. Lastly, the relationships between selected demographic variables and leadership styles displayed by family business owners were tested by means of an Analysis of Variance (ANOVA). Five factors were extracted from the EFA, four of which were considered for further analysis. The four usable factors extracted could be identified as the theoretical dimensions of Ethical leadership, Participative leadership, Perceived business performance and Servant leadership. The items measuring Ethical and Authentic leadership did not load as expected, as several items measuring the two factors loaded onto one factor. The Cronbach’s alpha coefficients returned for the four usable factors extracted from the EFA were greater than 0.7, and thus the scales measuring the independent and dependent variables provided satisfactory evidence of validity and reliability. The findings of this study show that for both the family business owner and employee sample group, Ethical leadership returned the highest mean score, followed by Servant and Participative leadership. The great majority of the family business owners therefore agreed that they adopted these leadership styles. In addition the majority of family business employees agreed that the family business owner, for whom they worked, adopted these leadership styles. T-tests were conducted to assess whether the differences in mean scores returned by the two sample groups were statistically significant. Significant differences were found between the means scores returned by both sample groups with regard to the level of Ethical and Servant leadership displayed by the family business owner. No significant difference was found between the mean scores returned by both sample groups for Participative leadership. This finding was not surprising, given that socially desirable bias occurs when individuals describe or rate themselves in a manner that is untruthful or in a way that they feel may be viewed favourably by others. From the MRA, no relationships were reported between the independent variables (Ethical, Participative and Servant leadership) and the dependent variable Perceived business performance. The results of ANOVA revealed that there was no relationship between the Gender, Age, Ethnicity, Tenure, Generation, Number of employees and the Nature of the family business and the Ethical, Participative, and Servant leadership styles. However, the results show that family business owners with a tertiary qualification are more likely to adopt a Participative leadership style. Despite no significant relationship found in this study, it is well supported in the literature that the leadership styles investigated have a positive influence on business performance. Family business owners should take cognisance of this, and measures should be taken to ensure that the leadership style implemented in their businesses is ethical, participative and servant-orientated. This study has attempted to enlarge the body of knowledge available on leadership, especially concerning the servant, ethical, people-centred and character-orientated leadership styles. The results of the study differ somewhat from existing literature, and therefore add to the body of knowledge on leadership. Furthermore, this study has addressed a gap in the current literature regarding the influence of leadership on business performance among family businesses in a developing economy such as South Africa.

- Description: Given the importance of family businesses with regard to the economic growth of South Africa, and the fact that their high failure rates have a negative influence on the country’s economy, this study focused on ineffective leadership among family businesses and the influence thereof on business performance. People’s perceptions of leadership are changing, and an ethical, people-centred, character-orientated approach to leadership may be what businesses require. In addition, innovation and employee well-being are being given high priority, and leadership that is ethical and caring is of great importance. The primary objective of this study was twofold, firstly to establish the levels of Ethical, Authentic, Participative and Servant leadership displayed by family business owners and employees in the Eastern Cape, and secondly to establish the influence on the Perceived business performance of the family business of displaying these styles. Poor leadership was identified as a major challenge that family businesses are faced with, and a challenge that contributes to their high failure rate. The literature dealt with the nature and importance of leadership, and both traditional and contemporary leadership styles were elaborated on. The traditional leadership styles identified were autocratic, laissez-faire, transactional, transformational and participative leadership, while the contemporary styles identified and discussed were ethical, authentic and servant leadership. From the literature it was evident that a more ethical, people-centred, character-orientated approach to leadership may be what businesses require to be successful today. The literature highlighted Ethical, Authentic, Participative, and Servant leadership as the more character-orientated leadership styles that positively influence the performance of any business, including family businesses. These leadership styles formed the main focus of this study. In this study a quantitative research design was adopted and a descriptive study of a cross-sectional nature was undertaken. A convenience sampling technique was used owing to the inaccessibility of a family business database. The sample size in this study consisted of 250 small family businesses. A survey was undertaken and a structured, self-administered questionnaire was used to gather the necessary data. The measuring instrument was developed by sourcing items from several existing studies. Family business owners and employees working in the family business were approached by fieldworkers and asked to participate in the study. In total, 266 questionnaires were usable, 133 from family business owners and 133 from family business employees. An effective response rate of 53.20 percent was achieved. The validity and reliability of the measuring instrument were confirmed by means of an exploratory factor analysis (EFA) and by the calculation of Cronbach’s alpha coefficients. Descriptive statistics were calculated in order to summarise the sample data, while t-tests were used to determine whether the differences in mean scores returned by the family business owner and employee sample groups for the leadership styles under investigation, were significantly different from each other. Pearson’s product moment correlations were used to assess the associations between the variables under investigation. A multiple regression analysis (MRA) was used to assess the relationships between the independent variables and the dependent variable Perceived business performance. Lastly, the relationships between selected demographic variables and leadership styles displayed by family business owners were tested by means of an Analysis of Variance (ANOVA). Five factors were extracted from the EFA, four of which were considered for further analysis. The four usable factors extracted could be identified as the theoretical dimensions of Ethical leadership, Participative leadership, Perceived business performance and Servant leadership. The items measuring Ethical and Authentic leadership did not load as expected, as several items measuring the two factors loaded onto one factor. The Cronbach’s alpha coefficients returned for the four usable factors extracted from the EFA were greater than 0.7, and thus the scales measuring the independent and dependent variables provided satisfactory evidence of validity and reliability. The findings of this study show that for both the family business owner and employee sample group, Ethical leadership returned the highest mean score, followed by Servant and Participative leadership. The great majority of the family business owners therefore agreed that they adopted these leadership styles. In addition the majority of family business employees agreed that the family business owner, for whom they worked, adopted these leadership styles. T-tests were conducted to assess whether the differences in mean scores returned by the two sample groups were statistically significant. Significant differences were found between the means scores returned by both sample groups with regard to the level of Ethical and Servant leadership displayed by the family business owner. No significant difference was found between the mean scores returned by both sample groups for Participative leadership. This finding was not surprising, given that socially desirable bias occurs when individuals describe or rate themselves in a manner that is untruthful or in a way that they feel may be viewed favourably by others. From the MRA, no relationships were reported between the independent variables (Ethical, Participative and Servant leadership) and the dependent variable Perceived business performance. The results of ANOVA revealed that there was no relationship between the Gender, Age, Ethnicity, Tenure, Generation, Number of employees and the Nature of the family business and the Ethical, Participative, and Servant leadership styles. However, the results show that family business owners with a tertiary qualification are more likely to adopt a Participative leadership style.

- Description: Publisher version , The effect of mouth status on the population structure of three endemic estuarine-spawning fish species was assessed using seine nets from November 2005 to October 2007 in the temporarily open/closed Mpekweni Estuary, Eastern Cape, South Africa. Collectively, these three species accounted for more than 60% of the total fish abundance within the estuary. Monthly length frequency data were analysed. Two species, Gilchristella aestuaria and Glossogobius callidus, displayed normally distributed populations throughout, with recruitment/abundance peaks between spring and autumn, and were unaffected by open mouth and extended marine connection conditions. Atherina breviceps, however, displayed multiple modal peaks in its combined population distribution, suggesting a greater influence of mouth condition on its population structure. Retrospective analyses of the various cohorts for A. breviceps identified peaks in recruitment/abundance during summer, coinciding with open-mouth conditions and, to a lesser extent, with overwash events. This study highlights the importance of mouth phase, not only on the recruitment and population distribution of marine-spawning species, but also on estuarine-spawning fish in temporarily open/closed estuaries along the South African coastline.

- Description: This study was conducted at a small ‘research-led’ institution in South Africa. The data indicate that women produce less research than men and have low levels of professional self-esteem. Factors such as accrual of social capital, family responsibilities and self-esteem are constraints experienced by women academics in pursuing research careers. Mentoring was found to facilitate research career development and improve levels of self-esteem. Improved self-esteem enables women to promote themselves within their institutions and in the research arena. The role of the head of department with mentoring as a key function emerged as an influential structure for the career advancement of women academics. However, these leadership positions are significantly dominated by men and this appears to affect the amount and nature of mentoring women academics receive.

- Description: The current orthodoxy among academics in higher education studies is that content and language learning should be integrated in order to facilitate communicative competencies in degrees seeking to prepare students for business and professions such as accounting, engineering and pharmacy. Content and Language Integrated Learning (CLIL) has been well-theorised and its goals are laudable; however, we contend that a one-size-fits-all solution of complete integration is not the most practicable or pedagogically-sound option in all contexts. Instead, we argue that establishing relationships of Informed Interdependence between content and language courses may offer greater benefits in specific contexts. This argument may appear counterintuitive, but we believe it has significant insights to add to the continuing dialogue around the use of CLIL. Accordingly, we describe a Professional Communication course at Rhodes University and then outline how we have responded to changes in our context through a process of engagement which led to a new course, namely, Professional Communication for Accountants, and recurriculation of the original Professional Communication course. In reporting on this process we foreground the importance of suitable boundary objects and discursive spaces around which interdisciplinary collaboration can occur. We provide staff and student reactions to a pilot project designed to test the curricular innovations made thus far, and conclude by reflecting on the efficacy of an Informed Interdependence model in our context.
