- Description: The emergence of urban social movements in the Zimbabwean context is mainly attributed to the political economic crisis, which resulted in the decline of municipal services and other socioeconomic rights central to the ordinary people. In the rural areas many scholars have alluded to the failure of the state to institute a radical transformation of the rural areas as the reason for the emergence of land movement and the subsequent land revolutions that followed in the early 2000s. Within this context, this study sought to investigate the social and structural basis for the emergence of social movements in Zimbabwe. The argument of this study hinges on the central premise of the political opportunity structure approach, which states that the emergence and success of social movements depends on certain political opportunities within the political environment. Building upon the guidance of the qualitative paradigm, whose method of investigation includes in-depth interviews and focus group discussions, the findings illustrate that the emergence of rural social movements in Zimbabwe was mainly to address the land question; such initiatives were to be done through fighting imperialism that hinges upon neo-liberal policies. In addition, one of the objectives for the emergence of rural social movements was to complete the objective of the liberation war, which was to give back the land to the indigenous black people. The tactics of the rural social movement included engaging the state and confronting it in other instances. Further, illegal land occupations were also one of the tactics of this movement. Ideologically, the movement used a Pan-African ideology to confront neo-colonization. On the other hand, the findings of the study illustrate that the emergence of urban social movements was mainly to provide a platform for the marginalized people to voice their discontent of the decline of service delivery in the urban context. Since most of these aspects were linked to the broader economic crisis facing the country, urban social movements also intended to initiate a political transition. The tactics of urban social movements included disruption, the establishment of networks with other social movements and the use of media, while constructing their ideology within the human rights framewo

- Description: The leerfish (Lichia amia), is a large, primarily coastal recreational fish species with a distribution extending from Portugal down the west coast of African to southern Mozambique. Owing to its large size (30 kg), strong fighting abilities and habit of taking surface artificial lures, this species has taken on an iconic stature among shore-based recreational anglers. Its reputation has made it an important angling tourism species that makes an important contribution to the economy of developing countries. For example, the species brought US$243 per harvested kilogramme into the local southern Angola economy. Despite its high value, little is known about its movement patterns in the northern Benguela coastal region, a region which includes southern Angola and northern Namibia. While much is known about the migratory patterns of the South African stock of L. amia, recent molecular studies have shown that the northern Benguela stock of L. amia has been isolated from the South African population for at least two million years, a consequence of the development of the cold Lüderitz upwelling cell in southern Namibia. Although the global population of L. amia is considered a single species, prominent biogeographic barriers within its distribution and subtle morphological differences between specimens captured within its tropical versus warm-temperate distribution suggest otherwise. A multi-method approach incorporating passive acoustic telemetry (PAT), recreational catch-per-unit-effort (CPUE) and conventional tagging (CT) in southern Angola, as well as recreational fisher-ecological knowledge (FEK) from Namibia, was used to investigate the large-scale movement patterns of L. amia within the northern Benguela coastal region. While each method had its own associated limitations, the combination provided a holistic picture of the population's seasonal migratory patterns. Furthermore, PAT successfully identified partial migration with 25% vs 75% of monitored fish exhibiting resident (movements < 100 km) or migratory (movements > 100 km) behaviour, respectively. Further behavioural diversity was observed with ‘resident’, ‘roaming’ and ‘embayment’ contingents identified based on varying levels of affinity to certain habitats. The presence of both resident and migratory individuals within the northernmost study during June and July, combined with available biological information, suggested that area-specific spawning may take place. While PAT, CPUE and CT largely aligned in determining area specific high-area use, results from network analyses and mixed effects models conducted on the PAT data supported the spawning hypothesis, with anomalous behaviour around specific receivers during the spawning season. All fish, regardless of behavioural contingent, displayed similar movement behaviour during the spawning season and this was driven by factors generally associated with reproduction, such as lunar illumination. Interestingly, these drivers were different from those that determined the area specific use of individuals outside of the spawning season. The environmental drivers of longshore migration into the northern study site were identified as a decline in water temperature and shorter day lengths. The results of this study highlight the importance of using a multi-method approach in determining migratory movement behaviour, area specific area use, and stock structure of key fisheries species. The identification of different behavioural contingents highlights the importance of acknowledging individual variation in movement and habitat-use patterns. This is particularly relevant as future climate change and spatiotemporal variation in fishing effort may artificially skew natural selection processes to favour certain behavioural groups. This study also highlighted the importance of scientists forming relationships with resource-users, such as recreational angling lodges in areas where limited research has been conducted. This is particularly relevant within the West African context where little is known about many of the fish species that are being increasingly targeted by tourism angling ventures.

- Description: Egeria densa Planchon (Hydrocharitaceae) is a submerged macrophyte native to South America. It forms part of a new suite of invasive aquatic plants that has benefited from open nutrient-rich freshwater systems following the successful biological control of floating aquatic plants in South Africa. The specificity of the leaf-mining fly, Hydrellia egeriae Rodrigues (Diptera: Ephydridae) was tested, using traditional laboratory host-specificity testing (i.e., no-choice and paired choice). Only one non-target species, Lagarosiphon major Deeming (Hydrocharitaceae) supported larval development during pair-choice tests. In order to avoid the rejection of a safe and potentially effective agent, continuation (i.e., multiple generations) tests were conducted to measure the ability of the non-target species to nutritionally support a population indefinitely. None of these species could sustain a viable agent population for more than three generations. Laboratory host-specificity tests are limited as they exempt certain insect-host behaviours. To enhance the interpretation of host-specificity results, a risk assessment was conducted using agent preference (i.e., choice tests) and performance (i.e., choice and continuation tests) results. The feeding and reproductive risk that H. egeriae poses to non-target species is below 2%. Based on these findings, permission for its release in South Africa has been obtained.

- Description: South African Government projects are frequently completed with large cost overruns, extended schedules, quality concerns and an increase in emerging contractors making a significant loss in projects they undertake. The construction phase has been the focus of many studies on the causes of unfavourable project outcomes. However, the crucial stages in the construction process that influence the success of a project are the early ones. This is where major decisions that influence the features and form of a project occur. This study, which adopts a case study approach, aims to establish the influence of the brief development process on the outcome of Government projects in the Eastern Cape. Through the reviewed literature and primary data collection, the study aimed at establishing the influence of the brief that is utilised for a need analysis, to define a detailed scope of works, stakeholder engagement and the time management on Eastern Cape Government project outcomes. The Sarah Baartman district was the selected geographical scope of research. Five projects were selected; these included three schools, one emergency medical service facility and one office facility. The study revealed that Eastern Cape Government projects brief development is based on the client department 2013 Published Norms and Standards for state buildings and a need analysis for other stakeholders is not considered. The study further revealed that there is no stakeholder management in government projects; therefore, there is no stakeholder engagement plan during the brief development. The study further revealed that government time management is suboptimal because stakeholder needs are not realised. The research also found that Eastern Cape Government projects do not achieve stakeholder satisfaction and are delivered late. However, some Government projects are able to meet the desired quality and are within budget. The study thus proposes that the Eastern Cape Government projects need to adopt the dynamic brief development process and implement stakeholder management. The brief development process should be an ongoing process extending throughout the project life cycle responding in an innovative manner to emerging stakeholder requirements.

- Description: The importance of voluntary non-remunerated blood donation is emphasised by the WHO, who envision a world with a sustainable blood supply where at least one percent of the population of every country voluntarily give blood. To ensure an adequate supply, the South African National Blood Service collects around three-thousand units of blood per day – forty percent of this from high school pupils and university students, following WHO recommendations regarding this segment as a target donor population. Despite the contribution by this segment of the population, no published knowledge exists of the perception of blood donation amongst university students in the country. This is an issue as the WHO (2010) recommends that countries understand what their populations know, think, and do regarding blood donation. In response to this issue this study investigated the perception of blood donation amongst students at a South African university (the Nelson Mandela University) to develop an understanding of what students know, think and do regarding blood donation. The study was conducted between 2017 and 2018 at a campus (‘South Campus’) of the Nelson Mandela University, Port Elizabeth. The study followed a qualitative approach, applying a thematic analysis. Data was collected through semi-structured person-to-person interviews among a sample of students (n=20) from different departments and disciplines.

- Description: While there has been substantial research on loyalty programmes, few studies specifically focus on the attitudinal and behavioural components of a loyalty programmes within grocery and retail sector programmes in South Africa. This study is part of a broader study of South African loyalty programmes, but specifically examines the attitudinal and behavioural influences on loyalty programmes in the South African grocery and retail sector. A comprehensive literature review was conducted and factors influencing loyalty programmes were identified. The literature reviewed informed the conceptual model that proposed purchasing behaviour, trust, communication, personalisation, flexibility, rewards and method of participation influenced the success of grocery and retail sector loyalty programmes with attitude and behaviour serving as intermediate variables. The academic literature selected for the study is grounded in the academic theories of social exchange and planned behaviour. The methodology followed was through self-administered questionnaires developed from academic literature. Data were collected from 1090 respondents across South Africa, of which 643 respondents were members of grocery and retail sector loyalty programmes. The data analysis conducted through various descriptive and inferential statistical tests and exploratory factors analysis identified that factors of purchasing behaviour, trust, communication, personalisation, flexibility, rewards and general assessment were factors influencing loyalty programmes. Loyalty programme studies in South Africa are generally conducted on specific loyalty programmes, which are owned by the programme owners and therefore unpublished. This study contributes to the body of knowledge by using academic theory to establish the attitudinal and behavioural factors that affect loyalty programmes within the South African grocery and retail sector. The study concludes with managerial recommendations that grocery and retail sector managers can implement to influence the success of loyalty programmes. Some of the recommendations include the use of communication as a lever to influence other factors and the overall effectiveness of the programme. Other recommendations include data management and rewards that create flexible and personalised experiences.

- Description: In the study, the researcher assessed the effects of amalgamations on organisational culture in the Raymond Mhlaba Local Municipality in Eastern Cape Province. The study examined whether the current organisational structure is conducive to a sound working environment, analysed change management interventions provided after the amalgamation and made recommendations to the local municipality on the measures to be taken to provide quality service delivery, improved communication networks and challenges that affect organisational culture. The entire research process was guided by the above research objectives and questions that strive to assess the outcomes of the effects of an amalgamation on organisational culture in Raymond Mhlaba. The study involved a qualitative research approach, and interviews were conducted for the administrative employees of the municipality. The findings of the study identified that the municipal amalgamation has negative effects on organisational culture, especially at the beginning of the amalgamation. The study established that there are many factors that led to the negative effect of an amalgamation on organisational culture, such as lack of management communication, consultation and planning strategies, preferential treatment, conflict and confusion, service delivery and failure to provide change management interventions. The study also revealed that the amalgamation came with better opportunities in terms of salary scales as the municipality is be more capacitated. These factors can be prevented to ensure the success of amalgamations in Local Government. Finally, the study makes recommendations for the municipality on how 10 to handle the amalgamation better, to result to a positive effect on organisational culture.

- Description: Network Telescopes, Internet backbone sampling, IDS and other forms of network-sourced Threat Intelligence provide researchers with insight into the methods and intent of remote entities by capturing network traffic and analysing the resulting data. This analysis and determination of intent is made difficult by the large amounts of potentially malicious traffic, coupled with limited amount of knowledge that can be attributed to the source of the incoming data, as the source is known only by its IP address. Due to the lack of commonly available tooling, many researchers start this analysis from the beginning and so repeat and re-iterate previous research as the bulk of their work. As a result new insight into methods and approaches of analysis is gained at a high cost. Our research approaches this problem by using additional knowledge about the source IP address such as open ports, reverse and forward DNS, BGP routing tables and more, to enhance the researcher's ability to understand the traffic source. The research is a BigData experiment, where large (hundreds of GB) datasets are merged with a two month section of Network Telescope data using a set of Python scripts. The result are written to a Google BigQuery database table. Analysis of the network data is greatly simplified, with questions about the nature of the source, such as its device class (home routing device or server), potential vulnerabilities (open telnet ports or databases) and location becoming relatively easy to answer. Using this approach, researchers can focus on the questions that need answering and efficiently address them. This research could be taken further by using additional data sources such as Geo-location, WHOIS lookups, Threat Intelligence feeds and many others. Other potential areas of research include real-time categorisation of incoming packets, in order to better inform alerting and reporting systems' configuration. In conclusion, categorising Network Telescope data in this way provides insight into the intent of the (apparent) originator and as such is a valuable tool for those seeking to understand the purpose and intent of arriving packets. In particular, the ability to remove packets categorised as non-malicious (e.g. those in the Research category) from the data eliminates a known source of `noise' from the data. This allows the researcher to focus their efforts in a more productive manner.

- Description: Network Telescopes, Internet backbone sampling, IDS and other forms of network-sourced Threat Intelligence provide researchers with insight into the methods and intent of remote entities by capturing network traffic and analysing the resulting data. This analysis and determination of intent is made difficult by the large amounts of potentially malicious traffic, coupled with limited amount of knowledge that can be attributed to the source of the incoming data, as the source is known only by its IP address. Due to the lack of commonly available tooling, many researchers start this analysis from the beginning and so repeat and re-iterate previous research as the bulk of their work. As a result new insight into methods and approaches of analysis is gained at a high cost. Our research approaches this problem by using additional knowledge about the source IP address such as open ports, reverse and forward DNS, BGP routing tables and more, to enhance the researcher's ability to understand the traffic source. The research is a BigData experiment, where large (hundreds of GB) datasets are merged with a two month section of Network Telescope data using a set of Python scripts. The result are written to a Google BigQuery database table. Analysis of the network data is greatly simplified, with questions about the nature of the source, such as its device class (home routing device or server), potential vulnerabilities (open telnet ports or databases) and location becoming relatively easy to answer. Using this approach, researchers can focus on the questions that need answering and efficiently address them. This research could be taken further by using additional data sources such as Geo-location, WHOIS lookups, Threat Intelligence feeds and many others. Other potential areas of research include real-time categorisation of incoming packets, in order to better inform alerting and reporting systems' configuration. In conclusion, categorising Network Telescope data in this way provides insight into the intent of the (apparent) originator and as such is a valuable tool for those seeking to understand the purpose and intent of arriving packets. In particular, the ability to remove packets categorised as non-malicious (e.g. those in the Research category) from the data eliminates a known source of `noise' from the data. This allows the researcher to focus their efforts in a more productive manner.

- Description: The primary aim of this study was to investigate the extent to which the attraction of foreign direct investment (FDI) was impeded by an underperforming economy in the Western Cape Province between 2014 and 2017. In order to stimulate economic growth during the period under review, Wesgro, the organization invested with the mandate of attracting FDI to the Western Cape Province, was required to market and attract high volumes of FDI. As the Western Cape economy was not growing at the required rate, Wesgro set its FDI target ranges to within achievable levels. In order to create a foundation for understanding laws and economic policies relevant to marketing to attract FDI, this study reviewed regulatory frameworks for FDI in South Africa and the Western Cape Province. In addition, the National Development Plan (economic growth policy of South Africa) and the Western Cape Provincial Strategic Plan 2014-2019 (economic growth policy of the Province) were discussed. The research methodology of this study followed a descriptive research approach, analysing existing secondary data extracted from books, academic journals, research reports, Acts of Parliament, economic growth policies and annual reports from the 2013/14 to 2016/17 financial years. Relevant data emanating from reviewed regulatory frameworks, economic growth policies, official FDI and its various forms, academic debates on FDI and the strategic roles and approaches employed by IPAs when marketing to attract FDI to home destinations was withdrawn, analysed and the findings presented. The findings revealed that a weak growing Western Cape economy impeded the potential of Wesgro to attract FDI beyond its targeted ranges between 2014 and 2017. The findings also indicated that the Western Cape economy experienced lack of investment, low economic activity, low economic growth and high unemployment because Wesgro did not attract sufficient FDI to stimulate economic growth. High volumes of FDI are needed to stimulate the Western Cape Province’s economic growth. Based on the findings of this study, various recommendations were made on ways in which the Western Cape economy could grow.

- Description: This study explores people’s insights of personal branding by means of social networking. The continuously increasing competitive marketplace is creating a situation where people find it difficult to stand out from their peers. Personal branding affords the opportunity for people to be noticeable in competitive environments. This study used a qualitative research method employing two phases. The semi-structured personal interviews using a semi-structured interview schedule was conducted in the first phase, while the content analysis using criterion schedules analysing participants’ Facebook and LinkedIn social networks was done in phase two. The results of phase one of the study revealed that the majority of participants did not know what a personal brand was, but they believed they possessed a personal brand. Phase two of the study revealed that only a few participants had a coherently perceived personal brand and presented personal brands on both Facebook and LinkedIn. Phase two of the study also revealed that the majority of participants more prominently presented the skills necessary for the future work environment on Facebook rather than LinkedIn. In conclusion, the findings showed that most participants did not actively manage their personal brands across multiple social networking sites. They also did not effectively present the necessary skills for the future work environment on their social networking profiles.

It draws on language and customs which have shaped and defined me as a woman born in the South of KwaZulu-Natal. I write about how I have to conform to both a rural life and an urban one that forms my second world. I find myself having to switch between these lives, which benefits me a lot, and I feel a responsibility to bring hope to young people especially from the rural side, that nothing is wrong with being who and where they are. My writing is influenced by authors such as Nazim Hikmet, Mafika Gwala, and Mazisi Kunene who encourages black writers to write about their own customs and stories rather than embracing ‘western civilization’ and foreign languages. I also like the contemporary subjects and the humour in Dr Nakanjani Sibiya’s work.

- Description: Hsp70s are members of the heat shock proteins family with a molecular weight of 70-kDa and are the most abundant group in bacterial and eukaryotic systems, hence the most extensively studied ones. These proteins are molecular chaperones that play a significant role in protein homeostasis by facilitating appropriate folding of proteins, preventing proteins from aggregating and misfolding. They are also involved in translocation of proteins into subcellular compartments and protection of cells against stress. Stress caused by environmental or biological factors affects the functionality of the cell. In response to these stressful conditions, up-regulation of Hsp70s ensures that the cells are protected by balancing out unfolded proteins giving them ample time to repair denatured proteins. Hsp70s is connected to numerous illnesses such as autoimmune and neurodegenerative diseases, bacterial infection, cancer, malaria, and obesity. The multi-functional nature of Hsp70s predisposes them as promising therapeutic targets. Hsp70s play vital roles in various cell developments, and survival pathways, therefore targeting this protein will provide a new avenue towards the discovery of active therapeutic agents for the treatment of a wide range of diseases. Allosteric sites of these proteins in its multi-conformational states have not been explored for inhibitory properties hence the aim of this study. This study aims at identifying allosteric sites that inhibit the ATPase and substrate binding activities using computational approaches. Using E. coli as a model organism, molecular docking for high throughput virtual screening was carried out using 623 compounds from the South African Natural Compounds Database (SANCDB; https://sancdb.rubi.ru.ac.za/) against identified allosteric sites. Ligands with the highest binding affinity (good binders) interacting with critical allosteric residues that are druggable were identified. Molecular dynamics (MD) simulation was also performed on the identified hits to assess for protein-inhibitor complex stability. Finally, principal component analysis (PCA) was performed to understand the structural dynamics of the ligand-free and ligand-bound structures during MD simulation.

- Description: Alien invasive species have the ability to transform or alter environments, often causing severe ecological and/or economic impacts. Marine bioinvasions are occurring globally and are most often facilitated (intentially and accidently) through anthropogenic activities including the building of inter-oceanic canals, shipping and commerce. The Mediterranean mussel, Mytilus galloprovincialis, is a globally successful marine alien invasive species which was first recorded on the west coast of South Africa in the late 1970s and the south coast in 1988. This species is thought to have reached the Knysna Estuary in the early 2000s and has colonised all man-made hard substrata in the embayment of the estuary. Although there are studies on recruitment of M. galloprovincialis on the rocky intertidal coasts of South Africa, there is little information on recruitment of this species in more sheltered estuarine environments. This study aimed to determine recruitment levels of M. galloprovincialis and other bivalves within the Knysna estuarine embayment. To determine monthly recruitment, 10 recruit collectors/pads (plastic pot scourers) were placed at three separate locations within the embayment of the estuary for a week on a monthly basis for 20 months. In addition, recruitment of M. galloprovincialis over spring and neap tides and different lunar phases was also determined at two sites within the Knysna estuarine embayment during the main reproductive season in 2018. The pads were deployed three days before a neap/spring tide and then collected three days after the respective tide. Finally, to look at how rapidly M. galloprovincialis and other macroinvertebrates (when M. galloprovincialis was excluded) would re-colonise free space, 18 plots (15x15 cm), consisting of three treatments including a control (A,B and C), were cleared in M. galloprovincialis mussel beds and then photographed monthly for 12 months. Four bivalve taxa (Mytilus galloprovincialis, Perna perna, Ostreidae, unidentified mytilid) were recorded during the monthly study. Recruitment levels for all bivalves differed significantly (P < 0.001) between months and sites, with peak recruitment occurring from late spring to early autumn (November – March). Mytilus galloprovincialis recruitment levels were greater than other bivalves and were up to 4.5x greater than other taxa. Recruitment also varied between years possibly owing to differences in larval supply and/or environmental factors. Spatial variation in bivalve recruitment was observed throughout the study. The greatest recruitment was at the site (Thesen Island Wharf) closer to the entrance of the embayment. By contrast at the site (Railway Bridge) furthest from the entrance lower recruitment was found. This difference is possibly due to differences in hydrodynamics or other biological and/or environmental factors. A preliminary tidal study found that M. galloprovincialis had significantly higher (P < 0.001) recruitment levels over spring tides than neap tides at Thesen Island Wharf, whereas recruitment at the Railway Bridge on spring and neap tides was not significantly different. In the study undertaken in the reproductive season only, recruitment levels were high over a two week period during both a spring and neap tide, suggesting that factors other than lunar phase and the state of tide are more important in determining the timing and intensity of recruitment. The clearance plots created and photographed over a 12 month period showed that M. galloprovincialis rapidly occupied free space (eight months to virtually cover all free space) by encroachment from the adjacent mussel bed. Limpets and barnacles were only able to colonise cleared space when M. galloprovincialis was excluded, suggesting that the mussel has the ability to outcompete indigenous macrofauna for space. The high recruitment levels of M. galloprovincialis compared to other indigenous bivalves, as well as its ability to occupy space rapidly are traits that must contribute to the success of the invasion of this species within the Knysna estuarine embayment, particulary within Thesen Islands Marina and Thesen Island Wharf.

- Description: The process of conceptualization has long served to capture and represent our perceptions of the social world. Conceptual categories help to make sense of subjective experiences, and through discursive practices may come to construct conventional frameworks of knowledge. Consequently, frameworks operating as natural and immutable run the risk of ignoring the dynamic and diverse experiences of many individuals. Today, conceptual frameworks for gender identity are found as inadequately representing progressive social views on the existence of gender identities manifesting outside of the prevailing male-female binary. Within this space of conceptual contention, the diagnostic category of gender dysphoria has received considerable inspection and critique. In particular, it has been criticised as fundamentally controversial by classifying issues of identity within a clinical framework and, consequently, as contributing to the pathologization of all gender diverse individuals. Thus, efforts to reconceptualise and reimagine gender dysphoria may be found. In this research the concept of individuation, as understood within a framework of analytical psychology, is discussed as a potential consideration in reimagining the concept of gender dysphoria. An overarching framework of social constructionism was adopted within this research in examining how constructions of conventional knowledge come about through regulatory discursive and performative practices. The theoretical orientation of analytical psychology was used to frame the concept of individuation and its application to gender dysphoria. This perspective consulted queer theory as a further critical orientation toward the construction of gender identity. The chosen methodology took form as a dual systematic review using critical interpretive synthesis (CIS) to construct representative frameworks. Psychological literature on gender dysphoria (review 1) and individuation (review 2) was reviewed and synthesised. Review 1 identified conceptual inferences within the literature and assessed their role toward problematic gender discourse, while review 2 served as a contributory tool to critically assess whether the conceptual space was accommodating of the concept of individuation. Findings in review 1 identified contemporary gender dysphoria literature as reinforcing of problematic gender discourse. The prevailing clinical framework on gender dysphoria and gender nonconformity was iterated through conceptual constructs emphasising an experience of pathological distress or life dissatisfaction. As such, a cyclical pathologization of gender diversity is reconstructed through current representations within the literature. However, it was deduced that there are signs of resistance in the literature to the clinical model which challenge and counter the impact of problematic gender discourse. In review 2, individuation was framed by the literature as an intrapsychic facilitator supporting the integration of all aspects particular to the individual personality so that conscious identity becomes congruent with internal nature. Resultantly, one may experience psychosocial maturation and contribute to collective societal progression. For some, individuation prompts a differentiation from collective expectations in integrating one‘s inherent nature into expressed identity. Thus, gender nonconformity may be viewed as an expression of this differentiation when individuation drives the realization of this feature to be intrinsic and natural for the individual. Individuation was determined as incompatible with the category of gender dysphoria, but of value within the conceptual space where efforts to reimagine gender dysphoria are in place.

- Description: The process of conceptualization has long served to capture and represent our perceptions of the social world. Conceptual categories help to make sense of subjective experiences, and through discursive practices may come to construct conventional frameworks of knowledge. Consequently, frameworks operating as natural and immutable run the risk of ignoring the dynamic and diverse experiences of many individuals. Today, conceptual frameworks for gender identity are found as inadequately representing progressive social views on the existence of gender identities manifesting outside of the prevailing male-female binary. Within this space of conceptual contention, the diagnostic category of gender dysphoria has received considerable inspection and critique. In particular, it has been criticised as fundamentally controversial by classifying issues of identity within a clinical framework and, consequently, as contributing to the pathologization of all gender diverse individuals.

- Description: The aim of this study is to investigate the employee turnover of educators in the Butterworth Education District. In order to achieve this goal, it was necessary to review the literature on human resource management. The motivation of job satisfaction was used to utilise the full potential people so as to ensure quality products and services. This is a very complex issue owing to the wide range of internal and external factors that impact on it. The study employed a literature study to examine the employee turnover. Moreover, the study discussed the types, consequences and factors influencing employee turnover. It also discussed retaining strategies, steps to manage employee turnover and methods to reduce employee turnover. The findings of the study revealed that an overview of human resource management plays a key role in determining the survival, effectiveness and competitiveness of an organisation. Factors influencing employee turnover determine employee turnover, and one of these is the labour market, which is determined by economic conditions. The findings also revealed that the causes and consequences of employee turnover can impact both negatively and positively to the organisation. Thus, the management of the Department of Education should perhaps adopt intervention strategies to control the main factors. In this regard, the study made recommendations for the motivation of educators in carrying out the core business of teaching and learning. This would involve the adequate allocation of all resources and benefits that surround teaching and learning and the introduction of a retention policy, which might encourage qualified and productive employees to continue working for the Department and reduce the unwanted voluntary turnover of valuable employees.

- Description: A series of BODIPY dyes functionalised with boronic acid in the 3,5-positions were successfully synthesised and characterised by using various analytical techniques. The dyes were prepared through a slight modification of the conventional acid catalysed condensation method. Phenylboronic acid moieties were added as styryl groups at the 3,5-positions of the 1,3,5,7-tetrametylBODIPY cores using a modified Knoevengal condensation method. The addition of the styryls resulted in the main absorption band of the dyes red-shifting to the 630−650 nm region. The photophysical and electrochemical properties of these dyes were studied to determine whether the dyes are suitable for use in the fluorescent, colourimetric and electrochemical detection of glucose. Boronic acid moieties were added as bioreceptor recognition elements because they have an affinity for carbohydrates and therefore would be able to bind and “detect” glucose. The series of BODIPY dyes did not show a “turn-on” fluorescence effect upon addition with glucose at the physiological pH. This was attributed on the basis of molecular modelling to the absence of an MO localised on the boronic-acid-substituted styryl moieties that lie close in energy to the HOMO and LUMO that facilitates the formation of an intramolecular charge transfer state. However, colourimetric changes that are visible to the naked eye are observed at basic pH when glucose was added to the dye solutions. The dyes exhibited favourable electrochemical behaviour and were able to detect glucose directly in this context when glassy carbon electrodes are modified through the drop dry method. A series of Sn(IV) porphyrins with thienyl and phenyl groups at the meso-positions were successfully synthesised and characterised. Pyridine and tetrabutyl axial ligands were added to the porphyrins to limit aggregation. The optical limiting properties of these porphyrins and three styrylated BODIPY dyes were studied in benzene and dichloromethane. Dyes were also embedded in polystyrene and studied as thin films to further gauge their suitability for use in optical limiting applications. Second-order hyperpolarizability, third-order susceptibly, non-linear absorption with reversible saturable absorption and the optical limiting threshold, were the parameters studied. Three of the four porphyrins and the three styrylated BODIPY dyes showed favourable optical limiting behaviour, which was further enhanced when the dyes are embedded in polymer thin films.

- Description: Seamounts influence ocean dynamics and consequently the surrounding ecosystem. Zooplankton communities associated with seamounts may be influenced by various mechanisms related to increased retention,such as Taylor columns and/or enhanced local productivity, leading to increased predation pressure. Through this study we investigated mesozooplankton distribution and community structure in the vicinity of three shallow seamounts in the South West Indian Ocean (SWIO) during September 2016, December 2016 and April/May 2017 at La Pérouse, MadRidge and Walters Shoal respectively. The water-column was profiled at 42 stations using a CTD-F equipped with a L-ADCP and mesozooplankton was sampled with a Bongo net or a Hydrobios Midi MultiNet, both fitted with 200 µm mesh. Walters Shoal had significantly lower mesozooplankton total abundance and biovolume compared to La Perouse and MadRidge. La Perouse and MadRidge showed similar mesozooplankton community structures with steep Normalised Biovolume Size Spectrum (NBSS) slopes, indicating higher productivity and dominance of small organisms, compared to Walters Shoal where the slopes were flatter. Total and per taxon abundances and biovolumes at locations “On” and “Off” the seamount were similar, as was the size diversity for MadRidge and Walter Shoal. None of the environmental parameters tested had a significant effect on variability of the mesozooplankton community structure at the stations overall.

- Description: The primary objective of this study was to explore the interests, beliefs, attitudes and experiences of the parties to the PSBC in order to identify firstly, the significant paradigms shaping their behaviours and secondly, to evaluate the extent to which these paradigms facilitate or inhibit successful collective bargaining between the two parties as currently constituted in the PSBC. The secondary objective was to develop recommendations to the PSBC for improved relations between the parties. This study was a qualitative exploration of perceptions of labour-management relations in the Public Service Bargaining Council of Botswana. A phenomenological approach was adopted in this study to explore the parties’ perspectives, experiences of the labour-management relations from their description of the relationship. Data collection was done through interviews. An interview schedule with two sets of semi-structured questions, one for trade unions and another for public service management was used to guide data collection from participants. However, interviews were only done with the trade union party as the researcher could not interview management due the long process required for public service managers give interviews. The results of the study revealed a diverse and nuanced interrelation between politics, macroeconomic policy and culture impacting Labour-management relations in Botswana. Firstly, the results show two unique relationships affecting employment relations in the Botswana public service. The first relationship was between labour and state and the second between labour and management. The relationship between the state and labour is characterised by antagonism and subordination of labour to capital and the state in a bid to secure industrial peace and attract foreign direct investment. The labour-management relationship in the Botswana public service has been impacted or influenced the by managers who hold Paternalistic Unitarist employment views and the labour movement which exhibit a shift from pluralist to critical employment relations views. The 2011 public service strike was identified as an “anchoring event” which has transformed the labour -management relations in the Botswana public service from accommodation to antagonism.

- Description: The right to strike is a constitutional right and is integral to the process of collective bargaining. Collective bargaining tends to focus on sensitive issues like wages, as well as terms and conditions of employment. Resolving these issues often requires compromise from both parties through the collective bargaining process. However, in the earlier stages of labour law there was no collective bargaining. There was a master and servant relationship, there was no compromise, and it was limited only to the individual contract of hire. As much as a strikes are a constitutional right and are recognised by the law, they don’t seem to happen without violence and destruction of property. There are some views that view violence as being synonymous with strikes in South Africa. The legal framework is very clear and supports the right to strike, and emphasises that any demonstrations and picketing should be peaceful. Section 68(1)(b) of the LRA should be a solution to the violence that comes with unprotected strikes. This section refers to just and equitable compensation, it does not equate to full loss suffered and it also depends on the merits of each case. The ILO’s approach to illegitimate actions linked to strikes should be proportionate to the offence of fault committed. The Constitution saw South Africa making a clean break with the past. The Constitution is focused on ensuring human dignity, the achievement of equality and advancement of human rights and freedoms.1 According to the Constitution the right to assemble and demonstrate must be peaceful. According to Grogan the right is now seen as a necessary adjunct to collective bargaining and is constitutionally entrenched.2 The LRA supports participation in protected strikes. In cases of unprotected strikes allows employers to interdict that particular strike, sue for compensation in cases of damages and losses and also to discipline employees. The Regulations of the Gatherings Act (RGA) was introduced to reconcile the right of assemblers with the state’s interest in maintaining public order. Section 11 of this Act seeks to deter violence and discourages violation of others by ensuring that organisers are held liable. The LRA holds the trade union and its members liable for the damages and violence that is accompanied by unprotected strikes. Section 68(1)(b) seeks just and equitable compensation for damages caused during an unprotected strike. However even though there is recourse for the damages suffered during the protest, unprotected strikes still continue and the violence is still part of the strikes. It is proper to ask if this section is really serving what it was intended. Surely the intention of this section was to deter strikers from embarking on unprotected strikes as the LRA is very clear on the procedure to be followed before a strike action takes place. Another intention of this section is to curb the violence during strikes. This section seems to have fallen on deaf ears.
