Description: Although workers of Plectroctena mandibularis laid trails with their stings while foraging, the trails appeared to be for individual orientation, because they never recruited nestmates to prey. However, both workers and queens laid trails when recruiting nestmates of either caste to new nest sites. During trail-laying, fluted hairs on the posterior edge of tergite VI were dragged along the ground, presumably applying a pheromone to the substrate. Anatomical and behavioural evidence suggests that pygidial gland secretions moved from the intersegmental pygidial gland between tergites VI and VII into a fingerprint-like, lamellar cuticular reservoir on the pygidium, and from there via the hairs to the substrate. These results suggest that recruitment may be crucial to moving nests but of value only to certain types of foraging, and that recruitment might even have originated in the Formicidae in the context of colony relocation, and then secondarily evolved to assist foraging.

Description: Responsive to the perceived high risks of sexual coercion, unwanted pregnancy and HIV-infection of girls in particular, several South African sexual health promotion campaigns have used media targeting parents (mothers in particular) to instruct them on how sex should be talked about with young people to ‘risk-proof’ them. Such an instrumentalist public health discourse posits this intergenerational communication as an ‘ongoing discussion’ of events, feelings, issues and risk-safe practices around heterosexual sex negotiation. A Foucauldian view finds these conversational imperatives pitched against much-talked-about resistances to talking about sex; and the saturation with risk of ambivalent mothers and silent daughters. Mother-daughter communication about sex and sexualities – as an uneasy western ideal of attachment parenting – has tangled roots in psychoanalytic theory and feminisms where sex as the core of modern subjectivity is normalized, capacities for intimacy are trained, and affiliative sexuality is modelled in ways that balance the rights and responsibilities of sexual agency/citizenship. This paper begins with two narrative fragments from a sexual health campaign that addressed mothers and daughters, and recounts how these ‘stories’ produced derisive laughter when introduced into group discussions with young/older women. The paper follows two lines of exploration. Firstly, is western idealized fabrication of inter-subjectivity between mothers and daughters desirable and feasible in post-apartheid conditions of epidemic in South Africa? And secondly, what if the narratives of lives and experiences we offer by way of health education materials provoke uncertainties, gaps and interrogations about sex, mothering and communication, instead of offering homilies and solutions?

Description: This paper describes the assumptions and results of a study to assess whether cultivation of medicinal plants can serve as a tool for combined biodiversity conservation and poverty alleviation. The study was carried out in the Amatola region of Eastern Cape, South Africa, where sustained beliefs in medicinal plant use, also under non-traditional conditions, has resulted in an increase in commercial demands. It was based on the assumption of poverty alleviation not only referring to an increase in income and labour, but also an increase in social capital and human dignity. The study assessed the local perceptions of the use and cultivation of medicinal plants and the need for conservation of these plants, as well as the features of already ongoing cultivation practices and options for increased cultivation. It consisted of participatory assessments in three villages involving around 250 persons and participatory trials with 14 rural women selling medicinal plants on urban markets. The study indicated that the growing demand for medicinal plants is related to the great cultural significance attached to medicinal plants.

Description: This research project is an interventionist case study, oriented in the interpretive paradigm, which aims to investigate how selected Grade 7 participants develop conceptual understanding in solving algebraic problems as a result of participating in screencast interventions. The aim of my screencast intervention programme, which lies at the heart of this study, is to develop practices, inter alia, of how such devices and software may be “used to develop conceptual rather than procedural or decorative knowledge” (Larkin & Calder, 2015:1) in solving linear equations. The planned intervention was delivered in the form of a series of screencasts: these take the form of audio-video lessons with an emphasis on the visual impact, and were recorded using an application called Explain Everything. The screencast interventions were delivered via Google Classroom and included animations supported by such conceptual explanations of early algebra as are relevant to Grade 7 students, and in line with the South African Curriculum and Assessment Policy Statements - Department of Education, 2011. The fundamental components of an early algebraic equation that would be relevant to a Grade 7 student were considered and used to develop an analytic framework. This was based on a taxonomy designed according to four identified “clusters” in order to analyse the workings of the purposefully selected Grade 7 participants who were video recorded and questioned in a talk-aloud interview while they completed a post-intervention pencil-and-paper test. What emerges from this research project is that there is a significant need for specific and concentrated technology-based techniques, such as the interventions undertaken here, and that exploration and development in the field could benefit the delivery of a pedagogy for algebra. The pedagogical methods implemented and studied in the form of screencasts proved to be successful and were well received by the learners particularly in relation to the conceptualisation of “symbol sense” and transformation in early algebra. The structure and design of the screencast interventions were important in supporting the acquisition of these concepts and were demonstrated to be worthwhile tools for an epistemological application in a classroom or teaching context. , Thesis (MEd) -- Rhodes University, Faculty of Education, Education, 2021

Description: At the turn of the twenty-first century, advancements in technology evolved at an exponential rate. This surge was mirrored by the rise in popularity and uptake of social networking sites (SNSs), and more recently, by Instagram, especially among emerging adults. SNSs have become an indispensable part of our daily lives and are influencing the ways individuals communicate, and develop and maintain romantic relationships. The Couple and Family Technology (CFT) Framework describes how the ecological elements of technology influence the structures and processes of romantic relationships, and is the lens through which this study was interpreted. The aim of this study was to determine if there was a relationship between Instagram use behaviours and relationship satisfaction amongst university students. This study employed a quantitative research approach and utilised a correlational research design. Participants included a sample of Nelson Mandela University students (N = 231) who were recruited through the nonprobability sampling methods of convenience and purposive sampling. Data were captured online through two measures. The biographical and Instagram use survey measured three variables, namely, frequency of Instagram usage, frequency of monitoring one’s partner’s Instagram activity, and frequency of posting behaviour. The Relationship Assessment Scale measured relationship satisfaction. Significant negative relationships were found between relationship satisfaction and frequency of Instagram usage and frequency of monitoring one’s partner’s Instagram activity. This research study contributed towards the existing body of knowledge, theoretical model, as well as insights for future lines of study within the realm of cyberpsychology. , Thesis (MA) -- Faculty of Health Sciences, 2021

Description: Currently there is a perception in South Africa that projects undertaken on parcels of restituted land are experiencing a much higher failure than success rate. There are, however, a few projects that are reaping the rewards and uplifting their communities, as intended by the land redistribution program. One community in particular, located in Mpumalanga, called community A, is presently undertaking a development project. This development project is one of the most successful restituted land parcel projects ever in South Africa. The purpose of the study is to determine the critical success factors in this community development project that have allowed it to enjoy such high levels of success. Are these critical success factors different from the generic industry critical success factors and, if so, what are they? As informed through literature, the critical success factors focused on in this study are as follows: the influence of management, project communication, knowledge management, the role of senior management, business strategy, project success measurements, and training and development. For the empirical study, a physical questionnaire was handed to 35 management members currently employed in the community development project. The questionnaire requested the demographics of all participants and asked them to rate, using a five-point Likert scale, their perceptions of the present project activities and of the importance of the project activities mentioned in making the project successful. Participants had to indicate the extent to which they agreed with each statement in the questionnaire. The responses obtained from the survey were presented and analysed. The study found that the critical success factor “role of senior management” was the largest problem area in the restituted land development project. “Training and development opportunities” came in second, with both factor areas showing large variances. Recommendations have been given on how to address both these problematic areas in the development project and how future restituted land parcel projects can better utilize these factors to ensure successful project implementation and long-term project success.

Description: Estuaries occur at the interface between the terrestrial and marine environment and as such act as the last ‘filtering’ mechanism prior to nutrient pollution entering the adjacent ocean. This study focused on the Swartkops Estuary which is eutrophic and requires the removal of nutrients. The role of phytoplankton as nutrient filters and storage of nutrients by seagrass and salt marsh was investigated. This study found that phytoplankton temporarily took up a large percentage of dissolved inorganic nitrogen (max. 99%) and dissolved silica (max. 76%) and limited amounts of dissolved inorganic phosphorus (max. 18%). The amount of carbon, nitrogen and phosphorus stored by the salt marsh species Spartina maritima and Salicornia tegetaria and the seagrass species Zostera capensis were determined. It was found that the salt marsh grass Spartina maritima stored the most nutrients (149.61 ± 16.59 N g m-2 ; 105.44 ± 13.41 P g m-2 ; 1690.52 ± 168.90 C g m-2 ), while for the salt marsh succulent Salicornia tegetaria less nutrients were stored (27.01 ± 4.17 N g m-2 ; 22.97 ± 3.21 P g m-2 ; 458.66 ± 69.43 C g m-2 ). Zostera capensis also acted as a nutrient store (22.17 ± 6.94 N g m-2 ; 23.75 ± 4.70 P g m-2 ; 221.10 ± 26.74 C g m-2 ). The macrophytes were able to store nutrients for longer periods and thus prevent these nutrients from being exported into the adjacent ocean. On the contrary, phytoplankton uptake was temporary as the nutrients are released once the bloom decays. Without intervention there will be an increase of harmful algal blooms (HABs) and fish kills in the eutrophic Swartkops Estuary. Nutrient input from upstream wastewater treatment works, canals and stormwater run-off must be reduced. Conservation and management of the seagrass and salt marsh habitats is needed to ensure the long-term storage of nutrients , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

Description: South Africa, despite its relatively small size, is often called “a world in one country”. This phrase arises mainly from the range of oceanographic and climatic features; geological and geomorphological attributes, the diversity of human cultures, languages, races and religions; the mix of developed and developing economies; the wide range in political opinion and parties; the vast array of mineral resources; and finally, what biologists find most interesting of all, the richness of the indigenous flora and fauna. Although southern African aquatic scientists cannot boast an equivalent of the Cape Floral Kingdom, the stretch of coast between northern Namibia and southern Mozambique has a particularly rich marine biota, accounting for almost 15% of all the coastal marine species known world-wide. The richness of the ichthyofauna is due to a number of factors, including the variety of habitats around the subcontinent, ranging from coral reefs, kelp beds, sheltered bays, sandy beaches, exposed rocky shores, coastal lakes to estuaries. In addition, southern Africa is the meeting place of three great oceans and is thus the recipient of species from each of these separate faunas. In comparison to land vertebrates, the world’s fish fauna is by no means well-known, either taxonomically or with regard to the biology of the component species. Apart from the very large number of fish species (estimated to be approximately 40 000), and the difficulties posed by the medium in which they live, there are other reasons for the above state of affairs. An obvious and universal reason is the shortage of funding available for taxonomic, biological and ecological studies, with increasing emphasis being placed on aquaculture, mariculture and fisheries related work. This situation is unlikely to improve and many research institutions around the world are operating on shrinking rather than expanding budgets. The onus of responsibility to disseminate information on the world’s fish faunas therefore rests squarely on the shoulders of those who are fortunate enough to be employed in the fascinating field of ichthyology. This book, which is a major revision and expansion of an earlier monograph (Whitfield 1998), is an attempt to synthesize the available information on fishes associated with southern African estuaries and to highlight the importance of conserving these systems for both fishes and people of the region. Limited reference is made to international estuarine fish research due to space constraints and readers are referred to global ichthyological reviews in this regard. The estuaries of southern Africa (defined as south of 26°S latitude for the purposes of this book) are highly diverse, both in terms of form and functioning. They range from the clear Kosi Estuary entering the coral rich subtropical Indian Ocean waters on the east coast, to the turbid Orange River flowing into the cool upwelled waters of the Atlantic Ocean on the west coast. The estuaries of the subcontinent are fed by catchments with a wide variety of climatic and geological characteristics. For example, the cool-temperate west coast is characterized by good winter rains and relatively dry summers, whereas on the subtropical east coast the opposite rainfall pattern prevails. While most south-western Cape estuaries are fed by rivers with low suspended sediment levels, those of KwaZulu-Natal normally carry high silt loads during the rainy season. Between Mossel Bay and St Francis Bay, rainfall patterns show no distinct seasonal peak and relatively acidic waters with low nutrient levels enter a variety of estuarine types along this section of the coast. The Eastern Cape is a region of transition between the subtropical and warm-temperate biogeographic provinces, and is prone to both droughts and floods occurring during any season of the year. The southern African estuarine environment is an unpredictable and often harsh habitat to occupy, yet each year millions of larval and juvenile fishes enter and thrive in these systems. The fish species that utilize estuaries as nursery areas exhibit great diversity in size, body form, salinity tolerance, diet, habitat preference and breeding behaviour. There is also a complete gradation in terms of the dependence that each species has on the estuarine environment. These and many other issues relating to the biology and ecology of estuary-associated fish species in southern Africa are explored in the chapters to follow. It is my sincere wish that our improved knowledge of these species and their environmental requirements will contribute to the wise management and conservation of these valuable ecosystems. , 2022 Edition

Description: Cluster analysis of invertebrate communities in the Swartvlei estuary revealed that vegetated (Zostera capensis) sites were distinct from unvegetated ones. `Indicator species' for the eelgrass group included Melita zeylinaca, Loripes clausus, Natica tecta and Palaemon pacificus, whereas those for the bare sand community were Urothoe pulchella, Callianassa kraussi, Iphinoe truncata and Pontogeloides latipes. Infaunal bivalves comprised >60 % of the invertebrate biomass at Zostera sites but <5 % at bare sand sites. Conversely the infaunal anomuran C. kraussi dominated the sandy sites (>80 %) and was a minor component (<5 %) at eelgrass sites. The supratidal invertebrate community was dominated by Orchestia spp. which live and feed on wrack detritus. Litterbag experiments revealed that degradation of Zostera leaf wrack was rapid during the first thirty days after deposition but slow between 40 and 140 days. Laboratory experiments indicated that Orchestia consumption of wrack material could not account for the rapid weight loss recorded in the natural environment. Preliminary diet analyses of intertidal and infratidal zoobenthos revealed that most invertebrate species feed on detritus and associated microorganisms. Filamentous algae and diatoms dominated the gut contents of only three out of 18 macrobenthic species, and living Zostera was not an important food item for any invertebrate examined.

Description: Progress in South African estuarine ichthyology between 1946 and 1995 is reviewed. The early estuary surveys of the 1950s and 1960s resulted in the compilation of species lists for individual systems, but contained very little biological or ecological information on fishes. These surveys were superseded by both autecological and synecological studies in the 1970s and 1980s, which yielded descriptive and process-orientated information on a wide variety of species. Estuarine research during the 1990s has focused increasingly at the community level, with several review papers on the life-history styles of groups of estuarine-associated fishes being published. The last decade has also seen the departure of a number of senior estuarine ichthyologists from the field. This decline in available expertise has coincided with increased demand for ichthyological information to be used in decision support systems for the wise management and conservation of estuaries. It is suggested that these demands be seen as a challenge, with studies being directed towards providing the type of information needed for the maintenance of vital ecological processes within these systems.

Description: publisher version , The interaction of gold nanoparticles (AuNP) with human immune-deficiency virus aspartic protease (HIVPR) is modelled using a regime of molecular dynamics simulations. The simulations of the 'docking', first as a rigid-body complex, and eventually through flexible-fit analysis, creates 36 different complexes from four initial orientations of the nanoparticle strategically positioned around the surface of the enzyme. The structural deviations of the enzymes from the initial x-ray crystal structure during each docking simulation are assessed by comparative analysis of secondary structural elements, root mean square deviations, B-factors, interactive bonding energies, dihedral angles, radius of gyration (R g), circular dichroism (CD), volume occupied by C α , electrostatic potentials, solvation energies and hydrophobicities. Normalisation of the data narrows the selection from the initial 36 to one 'final' probable structure. It is concluded that, after computer simulations on each of the 36 initial complexes incorporating the 12 different biophysical techniques, the top five complexes are the same no matter which technique is explored. The significance of the present work is an expansion of an earlier study on the molecular dynamic simulation for the interaction of HIVPR with silver nanoparticles. This work is supported by experimental evidence since the initial 'orientation' of the AgNP with the enzyme is the same as the 'final' AuNP-HIVPR complex generated in the present study. The findings will provide insight into the forces of the binding of the HIVPR to AuNP. It is anticipated that the protocol developed in this study will act as a standard process for the interaction of any nanoparticle with any biomedical target.

Description: publisher version , To facilitate a deep understanding of the mechanisms involved in neurodegeneration and Alzheimer’s disease fundamental knowledge is required about the action and function of enzymes in the brain that not only metabolise arginine (neuronal nitric oxide synthase) but are closely associated with oxidative (superoxide dismutase; catalase; glutathione peroxidase) and/or nitrosative stress. In particular the focus extends towards enzymes that contribute to amyloid peptide aggregation and senile plaquedeposits (fibrillogenesis). Of special importance are the glycine zipper regions within these amyloid peptides, especially Aβ25-29 and Aβ29-33 (that contains two isoleucine residues) and the pentapeptide Aβ17-21 (that contains two phenylalanines), each generated by enzymatic cleavage of the intramembrane amyloid precursor protein. Use of antisense-sense technology has identified regions in each enzyme that are capable of binding with the amyloid peptides. After an initial inhibition of each enzyme there is an oligomerisation into soluble fibrils which accumulate and eventually precipitate. The use of nanoparticles do not just prevent but reverse the formation of these fibrils either by disrupting the binary adduct – enzyme-Aβ-peptide- or by reaction with, and therefore deplete, Aβ-monomers in solution and so block potential aggregation sites on the enzyme itself. Future therapy towards Alzheimer’s disease should target the C-terminal region of the amyloid precursor protein and substitute hydrophobic residues for the glycine amino acids within the glycine zipper region.

Description: publisher version , This interaction of silver nanoparticles (AgNP) with human immune-deficiency virus aspartic protease (HIVPR) is examined by molecular dynamics simulation using the Colores (Situs) package and biophysical techniques using UV–vis spectroscopy, dynamic light scattering, transmission electron microscopy and circular dichroism. The ‘docking’ of AgNP with HIVPR creates a complex [AgNP–HIVPR] to initiate a hypochromic time-dependent red-shift for the surface plasmon resonance maximum. MD simulations reflect large perturbations to enzyme conformations by fluctuations of both rmsd and B-factors. Increase in changes to electrostatic potentials within the enzyme, especially, with chain B, suggest hydrophobic interactions for the binding of the AgNP. This is supported by changes to mainchain and sidechain dihedrals for many hydrophobic amino acid including Cys95, Trp6 and Trp42. Circular dichroism spectra reveal disappearance of α-helices and β-sheets and increase in random coil first from chain B then chain A. During initial stages of the interactive simulation the enzyme is conformational flexible to accommodate the AgNP, that docks with the enzyme under a cooperative mechanism, until a more stable structure is formed at convergence. There is a decrease in size of the HIVPR–AgNP complex measured by changes to the gyration radius supporting evidence that the AgNP associates, initially, with chain B.

Description: Cyberbullying is a significant field of study within cyberpsychology and requires continued research and development in order to further literature and understanding in a South African context. An increase in cyberbullying results in an increased prevalence of the occurrence of psychological distress in the form of short-term consequences as well as long-term chronic impacts such as depression, anxiety, and decreased life satisfaction. This qualitative study aimed to explore and describe the experiences of young adults who have experienced cyberbullying and the perceived impact of this experience on their psychological well-being. Qualitative research is a flexible exploratory and descriptive approach to understanding the lived experiences of an individual and their subjective view of a specific phenomenon through an interpretivist paradigm. This study utilised purposive and snowball sampling of Nelson Mandela University students aged 18 – 25 years old to gain a total of 6 participants for data gathering through semi-structured interviews. This research process followed a retrospective perspective which focuses on the specific meaning-making and understandings which that individual places on that experience, in relation to their psychological well-being. Thematic analysis was employed to analyse the data and trustworthiness criteria and was utilised throughout to ensure the credibility of the study. It was found that cyberbullying, through multiple forms and methods, has various short-term and long-term perceived impacts in several spheres. The perceived psychological impacts occurred in the short-term and were internalised to extend to long-term impacts on psychological well-being, of which the majority were negative. There are influencing factors to the development, coping and management of perceived long-term impacts which reflect the outcomes on well-being. The findings of this study highlight the perceived impact of cyberbullying on young adults’ psychological well-being which is vital for future recommendations and intervention. , Thesis (MA) -- Faculty of Health Sciences, 2021

Description: In South Africa, Psychology has had a chequered past mainly due to its role in the justification of apartheid policies. Due to apartheid's socio-economic injustices, confidence in the applicability of psychological knowledge to South Africa's social problems was insufficient. Psychologists attempted to raise consciousness of the social relevance of psychology by contributing relevant knowledge and being reactive to social inequalities and related psychosocial issues affecting South Africa. This study aimed to conduct a content analysis of trends in research produced by Psychology Masters' students in the fields of Clinical, Counselling and Research psychology over a period of 5 years (2008-2012). The corpus of data was then compared with the key issues raised in the United Nations Development Programme's South Africa human development report (2003), along with a focus on articles published by Macleod (2004) and Macleod and Howell (2013). It emerged that Empirical Qualitative studies, based on post-modern frameworks, as well as HIV/AIDS, Knowledge Production, Assessment and Measurement and Programme development and evaluation, dominated psychological research. Participants were mainly urban, middle class adults living in the 3 wealthiest provinces. University students were the most popular participant group. While it is encouraging that students were attempting to engage with psychosocial issues, the limited number of key social issues addressed, the under-representation of certain sectors of the South African population, as well as the impact of socioeconomic status on well-being requires greater attention at Masters' level to ensure Psychology's psychosocial relevance.

Description: Lovedale was founded by the Glasgow Missionary Society as an eduational centre for Africans. Education was to be adapted to the lives of the Africans which would be a departure from the English classical tradition. This meant that emphasis was placed on vocational training and that academic education focussed on the study of English rather than the Classics. But the importance of mother-tongue education was also stressed. The missionaries placed emphasis on village education, whereby the African would be taught skills and crafts that would be useful to him in life. Education, they argued, should also aim at character-training and at spreading the Christian message. They also wanted to see co-operation between the Church and the State in the education of the African. Vocational education was designed to create African artisans who would be able to compete with Whites; but it also aimed at emphasizing the importance of industry in building up character. The Lovedale Press illustrates vocational training in progress, dealing with the difficulties that arose when African printers came into competition with Whites. But the missionaries also used the Press to propagate the Christian message and to promote African literature. An ideological rift began to open up between the missions and the new Black political beliefs of the Second World War. This led to the Lovedale Riot which is considered in the broader framework of sociopolitical unrest within the country. After the 1948 Election an ideological rift also developed between the missions and the State. This study concludes by examining the introduction of the Bantu Education Act and the Lovedale response to this. It was felt that although Bantu Education threatened to undermine their educational endeavour, they should nevertheless cooperate with the system in order to save what they had built up.

Description: This paper attempts to address the issue of hardening the internal secu-rity of an organisation’s network by easing its patch management. Tradi-tionally security has been modeled on a" hard outer shell" approach, with a firewall protecting the otherwise vulnerable internal network. With the advent of worms using such techniques as social engineering to by-pass the organisational firewall and installing trojans, this approach is no longer sufficient. As a result of these new attacks, emphasis should be placed on improving the security of the internal network. Most research agrees that prompt patching of security vulnerabilities would significantly reduce the vulnerability of these machines. However, this requires sys-tem administrators not only to keep abreast of the flood of patches, but to ensure they are deployed to every machine, in what could be a very large network. These difficulties are worsened by problems the patches themselves often create. This is a difficult task and the failure of system administrators to perform it is echoed in the recent spate of worm at-tacks, with some taking advantage of vulnerabilities for which patches had been released up to six months earlier.

Description: This paper attempts to address the issue of harden-ing the internal security of an organisation’s network by easing its patch management. A unified architecture to aid with this process is proposed, with the view towards the implementation of an open source, cross platform tool to solve this problem.
