- Description: The governance system in post-apartheid South Africa brought about the working together of the three spheres of government, namely, the National, Provincial and Local spheres in a principle of intergovernmental relations underpinned by a system of cooperative government. Cooperative governance is about intergovernmental integration and coordination which sees the three spheres of government working together and functioning in harmony to provide public services and meet the needs of communities effectively and comes together in the integrated development plan (IDP), the key strategic planning instrument at local government level. In developing the IDP’s, the Municipal systems Act requires cooperation between the different spheres of government with the IDP providing the basis for the alignment of policy, planning and budgeting processes across all spheres. The IDP is, therefore, very important to IGR as it is meant to coordinate the programs, plans and projects of national and provincial departments that are to be implemented at local government level. This research, therefore, investigates the IGR practices in local government planning in the Eastern Cape, focusing on the Amathole District Municipality. A qualitative research method was utilized in this study and data was acquired through secondary sources to achieve the aims and objectives of this study. Data that was gathered was analyzed using an analytical framework. The study revealed that although the Amathole District Municipality has IGR structures to coordinate the IDP development process and the involvement of these structures have brought some positive changes to the IDP process; however, there are challenges that are still crippling the process, thereby, leaving much to be desired. Consequently, recommendations based on the findings were offered.

- Description: Many modern day work environments require some degree of dual tasking, particularly the simultaneous performance of cognitive jobs alongside physical activity. The nature of such tasks is often job dependent and may require cognitive functions such as perception, decision making, memory, or response selection/execution in conjunction to task specific physical requirements. Previous research has indicated a possible relationship between concurrent physical and cognitive demands and task performance, safety and efficiency. However, this research is limited and inconsistent. The current study aimed to identify the interaction, if any, between concurrent physical and mental demands, and determine the impact of sensory modality and stage of information processing on this interaction, with specific focus on the performance, perceptual and physical responses during different types of cognitive tasks performed concurrently with a lifting task. 20 (10 male, 10 female) Rhodes University students participated in this study. Each participant performed 9 test conditions - a physical lifting task, a visual and an auditory memory task, and a visual and an auditory decision making task in isolation, as well as the lifting task concurrently with each of these cognitive tasks. Performance was recorded via accuracy and work output of cognitive tasks and the number of lifts for each condition. Perceptual measures were obtained via the Borg RPE and Subjective Workload Assessment Technique. Spinal kinematics were measured using the Lumbar Motion Monitor, while muscle activity of the Erector Spinae, Rectus Abdominis, Rectus Femoris and Biceps Femoris muscles were recorded using the Biometrix Data Logger surface EMG equipment. Mean results were analysed using a dependent T-test to observe any general interaction, and a Two-way ANOVA for the impact of sensory modality and stage of processing. Individual responses were also considered to gain better understanding of both intra and inter-human variability under the various test conditions. Results showed a significant decrease in cognitive performance, increased perception of physical effort, time pressure, mental effort and psychological stress under simultaneous physical and mental demands, while no significant differences in physical responses were observed. Further observations included increased dual-task interference during visual and decision-making tasks when combined with physical demands compared to that of auditory and memory tasks respectively. Individual responses showed large variability between individuals indicating the presence of positive, negative and non-responders to concurrent physical and mental demands. Results therefore imply an individual specific interaction between concurrent physical and mental demands that may or may not be detrimental to worker productivity, job error, injury rates and worker well-being, and that the type of cognitive task performed may impact this interaction.

- Description: Phishing in the electronic communications medium is the act of sending unsolicited email messages with the intention of masquerading as a reputed business. The objective is to deceive the recipient into divulging personal and sensitive information such as bank account details, credit card numbers and passwords. Attacks against financial services are the most common types of targets for scammers. Phishing attacks in South Africa have cost businesses and consumers substantial amounts of financial loss. This research investigated existing literature to understand the basic concepts of email, phishing, spam and how these fit together. The research also looks into the increasing growth of phishing worldwide and in particular against South African targets. A quantitative study is performed and reported on; this involves the study and analysis of phishing statistics in a data set provided by the South African Anti-Phishing Working Group. The data set contains phishing URL information, country code where the site has been hosted, targeted company name, IP address information and timestamp of the phishing site. The data set contains 161 different phishing targets. The research primarily focuses on the trend in phishing attacks against six South African based financial institutions, but also correlates this with the overall global trend using statistical analysis. The results from the study of the data set are compared to existing statistics and literature regarding the prevalence and growth of phishing in South Africa. The question that this research answers is whether or not the prevalence and growth of phishing in South Africa correlates with the global trend in phishing attacks. The findings indicate that certain correlations exist between some of the South African phishing targets and global phishing trends.

- Description: South Africa is a country where those who were oppressed in the past are trying to live in a society with their former oppressors. The youth of today appear to be carrying the anger, fears and uncertainties of the past. This could be the result of intergenerational transmission of prejudice, whereby memories of experiences, fears, anger and levels of anxiety may be absorbed by the next generation. The purpose of this study was to develop and implement an intervention programme that could assist adolescent learners in making their own informed decisions, despite the influences of the intergenerational transmission of prejudice. This was achieved by combining three theories, namely the transgenerational theory, historical trauma and social learning theory, with the principles of bibliotherapy. The research conducted was based in the interpretive paradigm, with the study methodology being qualitative in nature. The research design implemented was a case study. Data generation was achieved by utilising a variety of methods, namely open-ended questions, small focus groups and reflection journals. Analysis of the data was accomplished by applying a thematic analysis approach. The sample for this study was selected from a local, government high school and the participants consisted of a group of Grade 10 learners, who all held leadership positions in the school. The purpose of this study was achieved by utilising the principles of bibliotherapy to inform a programme to develop awareness of intergenerational transmission of prejudice. This was then combined with the principles of bibliotherapy, with scenarios taken from the animated film, The Land Before Time, to further assist in creating awareness and a better understanding of the intergenerational transmission of knowledge. Finally, the programme was used to equip the participants with the tools needed, to transfer what they had learnt from the programme to decisions they would need to make in their daily lives. This study has shown that the principles of bibliotherapy can be used to promote and develop awareness of intergenerational transmission of prejudice in adolescent learners.

- Description: This study seeks to investigate the efficiency and effectiveness of the process for providing government social grants to people with disabilities in the South African Social Security Agency (SASSA) Amathole District Municipality in order to determine the need for any improvement measures. Taylor’s scientific management theory and the Total Quality Management (TQM) concept were used to interpret efficiency in the functional activities of the officials working in the Disability Grant Unit in Amathole District. The study also sought to answer the question of whether exit programmes existed that were designed to assist the beneficiaries to support them and cater for their needs related to their disabilities. The study followed a qualitative method. Face-to-face interviews were conducted and the sample of this study consisted of ten participants who are working at Grant Administration. These participants included one General Manager; one District Manager; one SASSA doctor; one Head of Grants Administration in the district and six officials who are at lower levels of the hierarchy at Amathole District Municipality in East London service office. Thematic analysis was used to identify themes from the interviews. The findings of this study revealed that the majority of the respondents experienced challenges such as lack of assessment doctors, turn around-time, corruption, poor consultation, lack of managerial commitment and doctors regarding the assessment of applications. In this regards, the study made a set of recommendations on the measures and strategies that could improve efficiency in the provision of this service.

- Description: This thesis investigates the feasibility of using gestures as a means of control for localizing three dimesional (3D) sound sources in a distributed immersive audio system. A prototype system was implemented and tested which uses state of the art technology to achieve the stated goals. A Windows Kinect is used for gesture recognition which translates human gestures into control messages by the prototype system, which in turn performs actions based on the recognized gestures. The term distributed in the context of this system refers to the audio processing capacity. The prototype system partitions and allocates the processing load between a number of endpoints. The reallocated processing load consists of the mixing of audio samples according to a specification. The endpoints used in this research are XMOS AVB endpoints. The firmware on these endpoints were modified to include the audio mixing capability which was controlled by a state of the art audio distribution networking standard, Ethernet AVB. The hardware used for the implementation of the prototype system is relatively cost efficient in comparison to professional audio hardware, and is also commercially available for end users. The successful implementation and results from user testing of the prototype system demonstrates how it is a feasible option for recording the localization of a sound source. The ability to partition the processing provides a modular approach to building immersive sound systems. This removes the constraint of a centralized mixing console with a predetermined speaker configuration.

- Description: Absenteeism affects organisations in many different ways, therefore it is essential to investigate absenteeism with the aim of minimising absence levels. The focus of the research was to investigate absenteeism amongst blue-collar workers at a Global Logistics Supplier. The objectives of this research were to identify the main types of absenteeism, to compare the views of blue-collar workers and management on the causes attributed to absenteeism, to describe how absenteeism has been measured and managed, and to make recommendations to the company on ways to minimize absenteeism based on the findings. Quantitative data in the form of monthly absenteeism statistics relating to each leave type, was examined for trends relating to absenteeism levels amongst blue-collar workers at the company. Semi-structured interviews were then carried out with management and blue-collar workers to examine the causes of absenteeism and its management. The results showed that there was a discrepancy between the views of management and blue-collar workers at the company on the perceived causes of absenteeism. On the other hand, both management and the blue-collar workers identified Monday and Friday as the most prevalent days on which employees are absent from the workplace. This finding suggests that more research should be conducted on this trend in blue-collar workers. In exploring how absenteeism is dealt with, management within the company stated that discipline was the most effective way of keeping absenteeism levels low amongst employees. The limitations and delimitations of the research were recognised and further research ideas were given. It was also recommended that managers and supervisors address the workplace issues and identify when a worker’s performance and interpersonal relationships are strained in order to effectively minimise absenteeism. It is also recommended they implement a wellness programme.

- Description: The research addresses the marketing activities of BOS Ice Tea, a South African company, and whether they are reflective and grounded within their marketing activities. By analysing public data and interviewing the founding partners, Richard Bowsher and Grant Rushmere, the findings where compared against the marketing paradigms of Ottoman (1999) and the green marketing practices of Gittell et al. (2012). It was determined that the company engages in green activities, but does not communicate them clearly. Further, where the company did promote organic rooibos and sustainability, their actions were not reflective of these behaviours from an academic point of view. Thus, there was the potential for green washing. The research concludes with suggestions for a 4P’s green marketing framework, and comments on areas that need clarity.

My interest was to investigate participative management with regards to five HODs of the Albany Museum with a view to generating knowledge and insights that can be used to support senior management’s engagement with participative management at mid-management level. The research was informed by the interpretive paradigm. The interpretive paradigm does not concern itself with the search for broadly applicable laws and rules but rather seeks to produce descriptive analyses that emphasise deep interpretation and understanding of social phenomena through the meaning that the people assign to them. This study is mostly descriptive and presents the reality of participants from their own experience. Semi-structured interviews and observation capture ‘insider’ knowledge that is part of an interpretive methodology. The study found that participative management was both understood and generally accepted as a good way to manage an organisation, and even members who were critical of it could see its benefits. However, the fractured and diversified structure of the organisation calls for a particularly skillful application of this management approach, one which would also demand leadership and a greater sense of working towards what are called collegial models of management. Whether this is in fact desirable for a museum is debatable.

- Description: This research investigates the level of servant leadership within Rhodes University sport clubs. The goals of this research are to assess the perception the club members have of their chairperson and to key identify areas of development. The sport clubs at Rhodes University are partially run by chairpersons who are voted into the position by his or her peers of a sports club. The chairpersons work alongside Rhodes University employees who are a part of the Sports Administration team to oversee the running, scheduling and finances of the club. The sports clubs are representative of Rhodes University and it is the chairperson’s responsibility to ensure the club is lead and run effectively. Robert Greenleaf coined the term servant leader in the 1970s (Greenleaf, 1997). The servant leader is a leader who is driven by his or her followers, as leadership involves a leader serving his or her followers first and foremost (Greenleaf, 1977). The leader takes on a role that is supportive and contributes to their personal as well as their professional achievements (Smith, Montagno and Kuzmenko, 2004). A questionnaire consisting of 27 questions was drafted, of which were four demographic questions. A 5-point Likert Scale was used in order for the participants to respond to the questions. The questionnaire was drawn from a number of questionnaires available in literature on leadership and adapted to suit Rhodes University sports clubs. The questionnaire was distributed personally by the researcher, as well as through an online questionnaire. There were a total of 153 candidates who participated in the study. Descriptive statistics were used to analyse the data. The majority of the respondents had the perceptions that their chairperson displayed characteristics of a servant leader. Majority of the participants were in agreement of the questions asked in the questionnaire, which focused on many servant leadership qualities. The results will be handed over to the Head of Sports Administration in order for them to get an idea of their leaders’ characteristics and areas where they can improve upon.

- Description: Biological diversity in freshwater biomes is vital to maintain healthy, functioning ecosystems with resilience to disturbance and the impacts of climate change. Freshwater ecosystems provide essential resources to life on Earth. However, as increasing pressure is being placed on the environment by human population growth, the quality of freshwater resources and the health of these ecosystems are at risk. Mountain streams provide an important source of water and are usually less affected by anthropogenic stressors, compared to lowland freshwaters. These montane streams are therefore of important conservation value and due to their untransformed nature serve as ideal ecosystems for biodiversity studies and as reference sites for studies on environmental change. This study explores aquatic macroinvertebrate biodiversity of the southern Great Escarpment in South Africa. Species assemblages and the environmental variables of each site were sampled from first order streams across five different mountain blocks along the Great Escarpment. Additionally, mitochondrial DNA of three mayfly species (Afroptilum sudafricanum, Demoreptus natalensis and Demoreptus capensis), commonly occurring in the study area, was analysed to compare the genetic diversity between habitat specialist and habitat generalist species. A total of 2 595 macroinvertebrate specimens from 47 families and 86 species were collected with several interesting and potentially new species being discovered. Partitioned diversity analyses indicate that macroinvertebrate diversity varies across mountain blocks. Multivariate analyses indicate that differences in assemblages could be attributed to differences in environmental variables between sites, particularly water velocity, total dissolved solids and salinity. As these environmental variables reflect of the topography of the sites, differences in species assemblages was attributed to difference in topography and therefore biotopes present. Habitat-restricted mayfly species (D. natalensis and D. capensis), occur in distinct populations confined to mountains blocks. Isolation-by-distance analyses further emphasis that these species are genetically restricted by their habitat preference for mountain streams. In contrast, A. sudafricanum, a habitat generalist, showed no indication of genetic structure due to location or distance. Possible cryptic taxa and new species were identified within A. sudafricanum and Dermoreptus respectively. This study provides an important contribution to the baseline data of freshwater macroinvertebrate diversity for the southern Great Escarpment region and provides insights into the considerable genetic diversity of selected aquatic taxa across this region.

- Description: This research is presented in three sections. Section 1 presents the research report in an academic journal article format. Section 2 provides a comprehensive literature review and Section 3 describes the research methodology and methods employed during the research. Climate change is the most urgent challenge facing planet earth today. The Intergovernmental Panel on Climate Change (IPCC) fifth assessment report (AR5) clearly states, “Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. Recent climate changes have had widespread impacts on human and natural systems” (IPCC, 2014:2). The Renewable Energy Policy Network for the 21st Century (REN21) published the 10th annual edition of the Renewables 2015 Global Status Report, which illustrates the importance of a zero emissions energy sector (REN21, 2015). Despite the world’s average annual 1,5% increase in energy consumption in recent years, and average 3% growth in Gross Domestic Product, carbon dioxide (CO2) emissions in 2014 were unchanged from 2013 levels (REN21, 2015). The report findings state, “For the first time in four decades, the world economy grew without a parallel rise in CO2 emissions” (REN21, 2015:17). Renewable energy and improved energy efficiency is key to limiting global warming and avoiding dangerous impacts from climate change (REN21, 2015). With a view to the successful outcome of the 21st Conference of the Parties (COP21) in December 2015, renewable energy could contribute significantly in mitigating climate change and supporting the Sustainable Development Goals (SDGs), specifically SDG 7, on Sustainable Energy for All (SAIREC, 2015). South Africa has been rated the 15th most attractive destination for investment in the renewable energy sector and could become a renewable energy leader in the African continent, according to the Renewable Energy Country Attractiveness Index of EY (Ernest and Young) (EY, 2015).

- Description: Community-based organizations (CBOs) play a crucial role in sustainable development and hence it is important that they are promoted, guided and supported by state agencies and the private sector. The South African government encourages communities to establish co-operatives as a tool or strategy to address local social issues and risks and act accordingly. The purpose of this case study was to determine what aspects of the establishment and operation of a successful community-based environmental organization are producing sustained school and community projects. The study set out to investigate and audit the activities of a successful environmental CBO so as to determine how it has successfully sustained its school and community environmental projects. The reason for this investigation was to inform other CBOs and the state environmental agencies that support them on how to sustain their environmental activities in community and school contexts. The investigation was designed as an interpretive case study, which used document analysis, semi-structured interviews and observations to gather data. The gathered data was analyzed through inductive analysis to interpret and audit reported activities. Analytical memos were used to represent key themes in relation to the successful operations of the organization. Through auditing and reporting the activities in the analytical memos, analytical statements were developed. Those statements guided the discussion and informed the study‟s findings and recommendations. After investigating this CBO, it was concluded that, their success is a result of the establishment of a networking forum with different stakeholders and parties, community involvement in different projects, partnerships with local schools to develop and expand their curriculum practice, CBO networking locally and internationally and finally, their participation in annual and continuous environmental competitions/projects/programs. The insights gained and lessons learned will be used to advice and support community based co-operatives in environmental learning activities in school and community contexts as part of my ongoing work.

- Description: The South African education system is based on learner centred principles and encourages the development of critical thinking. This approach is reflected in the South African Qualifications Framework, which identifies critical thinking as a primary outcome of education. In the vocational Tourism programme, there is a link between the subject learning outcomes and critical crossfield outcomes. The role of the vocational college educator is central in facilitating the development of critical thinking skills of all learners. The purpose of this study was to investigate how the selected Tourism educators develop critical thinking skills of risk L2 students. I conducted the study in a selected FET College using a qualitative case study in order to gain deeper understanding of how the educators implement curriculum policy in their classrooms. This study used four data collection instruments to gain an in-depth understanding of the research topic. The findings of the study reveal that educators understand the value of teaching critical thinking. However, there is a gap between educators’ conceptual understanding of critical thinking and their instructional practice to develop critical thinking skills during classroom instruction. The findings also reveal that there are factors that hinder the development of at risk students’ critical thinking skills such as; limited English language proficiency, poor behaviour, and subject guidelines which do not provide educators with guidance on teaching critical thinking skills. The study recommends in-service training sessions that will support educators on how to teach critical thinking skills explicitly. This study also recommends the development of practical guidelines to enhance educators’ critical thinking teaching strategies. The findings of this research will assist me in improving the support that I provide to Tourism educators.

- Description: The Russian wheat aphid (RWA) (Diuraphis noxia Kurdjumov) is a major pest of cultivated small grains. It is particularly devastating because of is high reproductive rate which results in the growth of large populations which become damaging to its host plants. Development of resistant barley (Hordeum vulgare L.) cultivars is complicated as resistance is polygenic. As a result, the industry remains at risk now that the RWA has spread throughout South Africa. It has, as recently as, 2013, been identified in the SW Cape, which was previously geographically isolated. This is South Africa‟s principle barley growing region. Now a potentially huge problem exists. Therefore, it is imperative that an alternative to pesticide use is found. Testing potential innate resistance in barley cultivars is thus, critical. In this thesis, I present data on four barely cultivars where I have examined their resistance/ lack of resistance to three known RWA biotypes, RWASA1, RWASA2 and RWASA3. The barley varieties used were two economically important South African malt barley cultivars (S5 and SSG 564) along with two potentially RWA resistant Afghan accessions (CIho 4125 and CIho 4159). The RWA biotype population growth rates on each of the plants were determined over a 14 day period. The aim was to establish baseline data of the effects of RWA population growth on the host plants under ambient CO2 (380 – 400 ppm) conditions. The extent of RWA feeding damage was investigated at the cell level by examining saliva deposition and cell disruption using Transmission Electron Microscopy; at the tissue/vascular level using fluorescence microscopy, to determine the extent of callose formation; at a whole leaf level by recording percent chlorosis and leaf roll; and finally, at a whole plant level by measuring biomass loss.The experiments were repeated under elevated CO2 (450 ppm) to model any changes in RWA/plant interaction with respect to future climate change. The effects of an elevated CO2 environment and RWA feeding on host plant foliar N and C:N ratio were compared to ambient CO2 conditions, to provide a clearer picture of the potential nutrient drain that a feeding RWA colony exacts on its host. Of the varieties tested, the CIho accessions performed better than the two SA barley cultivars as the CIho accessions appeared to express a mild antibiosis resistance response as RWA populations, particularly those of RWASA1, were smaller than those observed on either S5 or SSG 564. In addition, less damage was evident in the two CIho accessions due to RWA feeding. II RWASA2 was the most virulent of the three RWA biotypes tested, followed by RWASA3 while RWASA1 was the least virulent. Under elevated CO2 conditions, RWA feeding damage was exacerbated but the trend of biotype virulence remained the same. Higher aphid population sizes were recorded under elevated CO2, meant that even the more resistant CIho accessions were overcome by the increased demand made by the larger aphid colonies on the host plants. The % foliar N data showed that under elevated CO2 aphid-free control plants had increased N levels in their leaves. Increased “food” supply (as shown by the increased N levels) therefore allowed significantly larger aphid populations to develop on the plants exposed to elevated CO2, due to improved nutrient status of the phloem sap taken up by RWA. The knock-on effect of a higher aphid population was increased cell disruption as a result of extensive probing, extensive formations of wound callose, with the result that phloem damage impeded nutrient flow through the vascular tissues which contributed to chlorosis and (eventually plant) death. The major conclusion from this study is that even a mild CO2 elevation resulted in an increase aphid population which may pose a severe and very real threat to a barley crop. Therefore, without effort to identify and deploy resistant barley cultivars, it could well be possible that future barley cultivation in South Africa may no longer be viable.

- Description: The Russian wheat aphid (RWA) (Diuraphis noxia Kurdjumov) is a major pest of cultivated small grains. It is particularly devastating because of is high reproductive rate which results in the growth of large populations which become damaging to its host plants.

As a result, the industry remains at risk now that the RWA has spread throughout South Africa.

- Description: Since the mid 70’s politicians have realized how important transport has become in the economy of South Africa and the advantages it has on growth, job creation and infrastructure. The result was involvement in the rules and regulations that govern South African transport in our country today. Economic growth has become a critical factor for the survival of economies as well as the future prospects of generations to come. The global recession which had a direct and indirect effect on South Africa has highlighted the importance. The question on how the National Development Plan could have an influence on local and national economic growth has developed as well as what the impact will be of the contribution road transport can make on the growth of the South African society and the economy. When the current road transport sector is taken into consideration, the need for a constructive plan that can assist transporters, drivers and businesses to grow and expand has been identified. The purpose of this study is thus to determine what the current economic situation in the world and in South Africa is as well as how the current political spheres are contributing to the national economy. An in-depth analysis of the National Development Plan has been done with emphasis on the effect on transport in general and the effect on road transport in South Africa. In order to accomplish this objective a detailed literature study was done which highlighted the academics information that pertains to the above mentioned topics. An empirical study that would measure the thought process and feelings about the National Development Plan and road transport has been conducted by means of a questionnaire. The results of the study have indicated that the National Development Plan could be an important tool and could have an enormous positive effect on the overall economic situation of South Africa and its citizens. In addition, the study has revealed that in the long term the effect of the plan could be to the advantage of the road transport sector. Factors that could contribute to the success would be features such as the planned improvements on the main transport corridors, upgrade of infrastructure and the controlling of environmental matters would have give a positive ring to it. On the other hand, recommendations to rectify and improve other issues such as corruption, leadership, maintenance backlogs and stricter laws and policies have been identified that are hindering businesses to grow and expand. Literature and data gained through the empirical study has indicated that the National Development Plan will improve South Africa’s economic situation. Respondents were optimistic about the plan and the overall feeling were that the plan will succeed in improving the road transport sector thus contribute to the National Development Plan objective to eliminate poverty and inequality by 2030.

- Description: In today‘s world, characterised by highly competitive global economies, organisations have realised the need for a positive approach in order to remain competitive, sustainable and to attract and retain talent. A positive approach to leadership and an organisational environment characterised by trust has been one of the fundamental tools towards achieving this goal. The main objective of the present study was to assess the existence of positive organizational approaches (authentic leadership and workplace trust) within the government of Lesotho, especially at a time when the country was facing difficulties. The study was descriptive in nature, and followed a non-experimental quantitative approach. The survey made use of a sample of 153 civil servants occupying positions from supervisory to senior management. Data was acquired through the use of an electronic questionnaire made up of two scales: one was a self-assessment instrument on authentic leadership adopted from Walumbwa and associates, and the other scale was on workplace trust developed by Natalie Ferres. The analysis of data involved descriptive statistics, t-tests, ANOVA, post hoc tests and Cohen‘s d. The results of the study provided evidence that there were high levels of the authentic leadership and trust in the workplace. Demographic variables were not found to influence the outcome of authentic leadership scores, however, education and managerial level were found to have an influence on organisational trust. The findings of the study provoked the researcher to call for an implementation of policy on positive training for management and for further research in this area.

- Description: The nursery role hypothesis provides an approach for assessing the nursery function of habitat types within estuaries. This study attempted to assess the nursery value of the dominant estuarine habitats in the Bushmans Estuary for Rhabdosargus holubi (Steindachner 1881) by analysing habitat complexity, relative abundance and behaviour of R. holubi and using stomach contents analysis and dietary diatom composition as indicative of feeding habitat. Structural habitat complexity was assessed in Zostera capensis (Setchell) seagrass and Spartina maritima (Curtis Fernald) salt marsh by sampling above-ground stem density and length, and total cover per unit area (Ct/At). Dimensionless habitat complexity indices such as the interstitial spatial index (ISI) at three magnifications and fractal geometry at two magnifications were used to further analyse habitat complexity. Above-ground biomass (P<0.05) in each season and canopy height (P<0.001) were significantly higher in salt marsh than in seagrass whilst stem density was significantly higher in seagrass than in salt marsh in each season (P<0.001). Each dimensionless index indicated that complexity is notably higher in seagrass than in the salt marsh. Using dimensionless indices that analyse complexity at different spatial scales provided a better analysis of habitat complexity than canopy height and biomass as it allowed for direct comparisons between habitat types. Underwater video cameras were deployed in seagrass, salt marsh and sand flat habitats to assess the relative abundance and behaviour of R. holubi. The relative abundance of R. holubi was significantly higher in seagrass than salt marsh and sand flats, whilst the behaviour of R. holubi indicated a high degree of habitat use in structured habitats and a low degree of habitat use in unstructured sand flat habitats. This indicated that not only are juvenile R. holubi a vegetation-associated species, but also a species that prefers seagrass to salt marsh.
