  • Description: Learning Management Systems (LMS) have the ability to transform learning experiences of students in Higher Education Institutions (HEI). In addition to the developmental benefits, LMS assist teaching and learning during student unrests, a common feature in historically disadvantaged institutions in South Africa. Regardless of the benefits of LMS platforms such as Blackboard, the utilisation by university students at the institution under study has been very low. Applying cross sectional electronic survey, this study identifies the key factors influencing technology adoption, as identified in the General Extended Technology Acceptance Model for E-Learning (GETAMEL), behind perceived ease of use and perceived usefulness in the adoption of technology. A sample of 125 students at a historically disadvantaged institution in South Africa was considered for the study. Data was collected to understand their perceptions on use of Blackboard Learning Management System (BB) for learning. Data was analysed with SmartPLS statistical analysis software. Results show that perceived ease of use of BB is influenced by computer self-efficacy, computer amusement and computer anxiety whilst perceived usefulness of BB is influenced by subjective norm and computer enjoyment. The findings also show computer experience to significantly affect computer self-efficacy and computer self-efficacy to affect computer enjoyment. The article presents the external factors that affect the usage of LMS at one of the historically disadvantaged HEI in South Africa. HEI leadership has to prioritise the identified external factors to increase chances of acceptance and utilisation of Blackboard by learners.

  • Description: Biological control (biocontrol) of invasive alien plants is a widely utilised weed management tool. Prospective biocontrol agents are typically assessed through host specificity testing and pre-release efficacy studies performed in quarantine. However, rearing of the potential biocontrol agents and/or test plants is often difficult or impossible under quarantine conditions. Moreover, practitioners may attain laboratory artefacts in quarantine, which may result in the potential agent being needlessly rejected. Field-based studies in the weed's indigenous distribution could overcome these issues.

  • Description: Plants of the genus Euphorbia are widely distributed across temperate, tropical and subtropical regions of South America, Asia and Africa with established Ayurvedic, Chinese and Malay ethnomedical records. The present review reports the isolation, occurrence, phytochemistry, biological properties, therapeutic potential and structure–activity relationship of Euphorbia flavonoids for the period covering 2000–2020, while identifying potential areas for future studies aimed at development of new therapeutic agents from these plants. The findings suggest that the extracts and isolated flavonoids possess anticancer, antiproliferative, antimalarial, antibacterial, anti-venom, anti-inflammatory, anti-hepatitis and antioxidant properties and have different mechanisms of action against cancer cells. Of the investigated species, over 80 different types of flavonoids have been isolated to date. Most of the isolated flavonoids were flavonols and comprised simple O-substitution patterns, C-methylation and prenylation. Others had a glycoside, glycosidic linkages and a carbohydrate attached at either C-3 or C-7, and were designated as d-glucose, l-rhamnose or glucorhamnose. The structure–activity relationship studies showed that methylation of the hydroxyl groups on C-3 or C-7 reduces the activities while glycosylation loses the activity and that the parent skeletal structure is essential in retaining the activity. These constituents can therefore offer potential alternative scaffolds towards development of new Euphorbia-based therapeutic agents.

  • Description: The hypoxic tumour microenvironment and poor spatiotemporal localization of photosensitizers are two significant obstacles that limit practical applications of photodynamic therapy. In response, a biocompatible, light-activatable liposome integrated with both a zinc phthalocyanine photodynamic component and Pt nanoparticles-decorated with MnO2 catalase-mimicking component are engineered. This multifunctional system was rationally designed using unsaturated phospholipids to achieve on-demand drug release following light irradiation. Specificity was achieved by folic acid functionalization resulting in folate-modified liposomes (FTLiposomes). We demonstrated its specific uptake by fluorescence imaging using folate receptor (FR) overexpressing HeLa and MCF-7 cells as in vitro models. This multifunctional liposome exhibits superior hypoxic anti-tumour effects and holds the potential to reduce side effects associated with untargeted therapy. Fluorescence of the constituent ZnPc and folate-receptor targeting could enable tracking and permit spatiotemporal regulation for improved cancer treatment.

  • Description: Invasive alien aquatic plant species (IAAPs) cause serious ecological and economic impact and are a major driver of changes in aquatic plant communities. Their invasive success is influenced by both abiotic and biotic factors. Here, we summarize the existing knowledge on the biology of 21 IAAPs (four free-floating species, eight sediment-rooted, emerged or floating-leaved species, and nine sediment-rooted, submerged species) to highlight traits that are linked to their invasive success. We focus on those traits which were documented as closely linked to plant invasions, including dispersal and growth patterns, allelopathy and herbivore defence. The traits are generally specific to the different growth forms of IAAPs. In general, the species show effective dispersal and spread mechanisms, even though sexual and vegetative spread differs strongly between species. Moreover, IAAPs show varying strategies to cope with the environment. The presented overview of traits of IAAPs will help to identify potential invasive alien aquatic plants. Further, the information provided is of interest for developing species-specific management strategies and effective prevention measures.

God Abhors Corruption: Some Thoughts on Acts 5:1-11 with special reference to the South African Countercorruption Efforts

  • Description: Corruption has become a buzz word the world-over today. South Africa is no less affected by it than are other countries. Many counter-corruption measures have been devised from a political perspective with no visible results. This reflection is an attempt to introduce a religious intervention. The article argues that the narrative of Ananias and Sapphira (Acts: 1-11) has all the elements of corruption as we know it today as well as a decisive response to it. Redaction criticism is employed in reading the narrative of Ananias and Sapphira with particular reference to the South African counter-corruption efforts. The reading reveals that God abhors corruption, this being inferred from the ‘double-deaths’ of the corrupt couple. A conclusion is therefore reached that drastic action against perpetrators is imperative and that trustees of state authority who fail to act against corruption and its perpetrators do not deserve to be rewarded with office. Keywords: corruption, counter-corruption efforts, Acts 5:1-11, consequence management, Ananias and Sapphira, koinonia community, South Africa

  • Description: This synopsis of the Grand Challenges of Urban Agriculture (UA) is framed by the urgent need to understand and strengthen the expanding yet highly diverse roles of UA amid rapid global urbanization, failures of predominant food systems, and crises in systems of physical and mental health. More than half of humanity lives in cities today and by 2030 this is projected to grow to 60.4 percent, ∼5 billion people (UN Habitat, 2020). More than 90 percent of urban demographic increase is anticipated to take place in the developing world. Ecological and social dimensions of UA are situated in these expanding spaces of cities, towns, and villages (along with their urban fringe or peri-urban areas), and among their diverse populations. UA is further situated in the powerful, far-reaching influences of urbanization processes that occur within and beyond these spaces. UA is thus integral to the prospect of Urban Sustainability as SDG 11 (“Make cities and human settlements inclusive, safe, resilient and sustainable”) of the U.N.’s 2030 Agenda for Sustainable Development.

  • Description: Economic growth is often assumed to improve happiness for people in low income countries, although the association between monetary income and subjective well-being has been a subject of debate. We test this assumption by comparing three different measures of subjective well-being in very low-income communities with different levels of monetization. Contrary to expectations, all three measures of subjective well-being were very high in the least-monetized sites and comparable to those found among citizens of wealthy nations. The reported drivers of happiness shifted with increasing monetization: from enjoying experiential activities in contact with nature at the less monetized sites, to social and economic factors at the more monetized sites. Our results suggest that high levels of subjective well-being can be achieved with minimal monetization, challenging the perception that economic growth will raise life satisfaction among low income populations.

  • Description: Heavy metal pollution is an increasing threat to the marine environment and is a major health concern. Both marine limpets and algae have been employed as biomonitors elsewhere in the world, but there are few or no data for these taxa along the South African coast. We investigated heavy metal concentrations in the tissues of selected limpet and algae species sampled at four sites on the southeast coast of South Africa (Silaka, Hluleka, Mthatha and Mbhashe), and determined whether there was any relationship between heavy metal concentrations in the limpets and their algae food sources as evidenced by the trophic transfer factor (TTF). Samples were collected in July 2019 and the tissues were digested following normal protocols. Heavy metals were detected using inductively coupled plasma optical emission spectrometry (ICP-OES). Significant differences in metal concentrations were observed among the algae species. The soft tissues of limpets from Silaka had the highest heavy metal concentrations, and samples from Mthatha had the lowest, with only mercury (Hg) occurring in high concentrations. Metal concentrations in soft tissues were generally 10-times higher than in shell tissues and differed between lower- and upper-shore species. Cadmium (Cd) biomagnified (TTF > 1) in all limpet species at all sites. Cd, arsenic (As), lead (Pb) and Hg measured in our study were above the maximum limits set by the South African Department of Health. This study suggests that the use of limpet and algae species as bioindicators is feasible since they are widely distributed and can accumulate a wide range of heavy metals.

  • Description: The geology of the SE limb of the Kromberg type-section, its origin and its evolution has remained controversial for more than five decades since its discovery by Viljoen and Viljoen (1969). Different lithostratigraphy and geodynamic models have been proposed that were centred around two end-member models, a continuous layer-cake stratigraphy model (Viljoen and Viljoen, 1969c, Lowe et al., 1999) or a tectono-stratigraphic model (de Wit et al., 2011, Furnes et al., 2012). Additionally, the Kromberg type-section mafic-ultramafic sequence represents a relatively thin, dismembered sequence compared to other formations or ‘complexes’ in the Onverwacht Group. Previous geology workers relied on the field interpretations for the construction of the geological architecture of the Kromberg type-section; but no petrographic analyses were conducted for accurate, integrated geological characterization of different rock compositions. To address controversies centred around the Kromberg type-section geology and geodynamic setting, this study is aimed at testing previously proposed stratigraphic and geodynamic models by integrating high-resolution geological mapping, petrography, mineral chemistry and whole-rock geochemistry to verify rock characterization. The aim is to accurately reconstruct the volcano-sedimentary architecture of the Kromberg type-section and to compare this to the results of previous fieldwork. Moreover, the manner in which the Kromberg sequence may relate to current Archean geodynamic models is evaluated, and a new model explaining the origin and evolution of the Kromberg type sequence is proposed. The integration of high-resolution field mapping, petrography and geochemistry has allowed for a high precision study and that has resulted in the construction of a new geological architecture for the SE limb of the Kromberg type-section. The stratigraphic thickness of the SE limb of the Kromberg sequence comprises dominant c. 80% volcanic rocks and minor c. 15% intrusive rocks, intercalated by 7 volcano-sedimentary chert horizons (c. 5%). Four main rock types (groups) are present in the Kromberg type-section with two sub-types of komatiitic basalts (the Badplaas-type and Geluk-types), Fe-rich tholeiitic basalt, cumulate peridotite, and a metadunite. Although the Kromberg type-section records sub-greenschist to lower greenschist facies, more than 50% of the rock samples classify as altered with parts of the stratigraphy recording extensive chloritization and severe ocean-floor silicification. Geochemical data revealed an enrichment in SiO2, K2O, Ba, Rb and variation in HREE for highly silicified samples whereas, chloritized samples are enriched in FeO and have concave upward LREE patterns. Partially chloritized tholeiites and komatiitic basalts have overlapping SiO2 signatures, relatively flat REE patterns and a small negative Nb anomaly in the primitive mantle-normalized spider diagrams. This thesis provides the first Lu-Hf isotope data on whole rock samples from the Kromberg type-section. The εHf values at t=3.33 Ga range between -0.62 to +4.18 and Hf model ages range between 3.43 - 4.27 Ga. The rock compositions are compared to the geochemistry of other greenstone belt rocks, which are considered to provide insight onto the geodynamic setting under which the Kromberg mafic-ultramafic sequence formed. The rock compositions reveal plume-related processes where a primitive mantle melt interacts with recycled mafic crust or mafic lower crust of older units of the Onverwacht Group. Only a small Nb anomaly is found in some samples and the data plots outside the subduction zone (forearc and back-arc) field. Rare-Earth element profiles are flat and not consistent with a subduction zone signature, as proposed in previous studies. Rifting of an oceanic floor in a juvenile basin is proposed for the formation of the Kromberg type-section rocks, prior to being tectonically accreted during regional transpressional deformation at c. 3.23 Ga.

  • Description: Although art therapy is recommended in management programmes for individuals with a diagnosis of schizophrenia, calls have been made for more detailed explanations as to how artmaking is working. This study responds to those calls by considering the artmaking experiences of 15 mental health users with a diagnosis of schizophrenia, resident at a forensic, mental health facility in South Africa. A phenomenological approach was chosen because of its focus on lived experiences, suited to explore the embodied and pre-reflective experience of studio-based artmaking. Dialogical and narrative understandings were subsequently incorporated to account for more reflective aspects of the artmaking experience. Two main participant descriptions of artmaking, centring on feeling at home and on doing something meaningful, guided the phenomenological lifeworld method in analysing the data (interviews, artworks and field observations in art groups and exhibitions), along selected dimensions of lived experience, namely embodiment, temporality, spatiality, sociality and selfhood. These findings lend support to new phenomenological research which suggests that artmaking intersects with disrupted abilities for perceptual engagement underlying manifestations of schizophrenia symptomology. This research supports assertions that artmaking has the potential to support the minimal sense of self and expand possibilities for renewed embodied and more reflective meaning-making. Explanations of findings centred around the distinct artistic style of each participant, as well as their artworks which revealed individual lifeworlds including a variety of self-positions. The inherent properties of the completed artworks also provided possibilities for renewed experiences of sociality. Additional support for the findings is drawn from recent research in the fields of early neurodevelopmental trauma, and trauma research findings within the art therapy field.

  • Description: Informal foraging for food and other natural materials in urban greenspaces is an activity undertaken by many across the world. For some, foraging is a necessary means of survival and livelihood, while for others, it provides cultural and recreational opportunities. In the socioeconomic crises induced by Covid-19, foraging can help communities, especially (but not exclusively) vulnerable people, cope with the impacts of lockdowns, and associated economic decline. In the long run, foraging can help improve social–ecological resilience in urban systems, particularly in response to climate, economic, and disease disruptions. First, we elaborate the ways in which urban foraging can provide immediate relief from the shocks to natural, human, social, physical, and financial capital. We then describe how over time, the livelihood, food, and income diversification brought about by foraging can contribute to preparedness for future uncertainties and gradual change. Cities are increasingly becoming home to the majority of humanity, and urban foraging can be one of the pathways that makes cities more liveable, for humans as well as other species we coexist with. Through the capitals framework, we explore the role foraging could play in addressing issues of biodiversity conservation, culture, and education, good governance and social justice, multifunctional greenspace, and sustainable nature-based livelihoods in urban areas.

  • Description: This study sought to investigate the experiences of leaders involved in a transition from specialist role to leadership role at the Eastern Cape Development Agency, South Africa. A qualitative case study within a constructivist paradigm was adopted. Bridges’ (1991) theory of transition was used in this study to understand and analyse the process of transition in this study. The study used purposive sampling technique, where six leaders were selected and interviewed. The data was analysed through inductive and content analysis techniques. The findings are presented thematically and supported with participants verbatim. The study established that as specialists transition to leadership roles they experience lack of role clarity, stress (role strain), resistance, inadequate support, shock, increased work load (role strain) and role conflict. These experiences influence on their role identity, expertise, peer relationships and financial status. The study also established that for smooth and successful transition, consultation, participation, proper succession planning, and training is vitally important. This was necessary to ease the tension between management, leadership, specialist responsibilities, and resistance from specialists. The study recommends adequate support and preparation in all stages of transition to ensure that the organization benefits from the transition.

Abstract Translation of children’s literature needs an artist who not only aims at producing the source language message in the target language, but will produce it in an appropriate manner and language to the target audience. In this case, the audience is children. The Skopos theory maintains that the translator needs to ensure that they fulfil the translation aim and the expectations of the target reader. This can only happen by using various strategies suggested by this and other functional equivalence theories. The researcher has used the Skopos theory to critically analyse children’s texts translated from English into isiXhosa. In the critique, the researcher noticed some errors in the translations, which may end up discouraging the child reader from reading such texts. This article explains the errors found in the texts and how they could be averted. The findings were that there are errors that happen because the translator is faithful to the source language, while there are others that are caused by nonconformity to the target language conventions. Some of these errors are so common in isiXhosa that it is possible that they are no longer considered errors by the translators. One of the recommendations is for the translator to reread the translation before they forward it to the editor and proofreader.

  • Description: Although extensive studies and investigations exist within provincial and national spheres of the craft making and trading sector in South Africa, most of these investigations have aimed to conceptualise craft and the identification of the obstacles, as well as the demurred in the craft industry as whole. However, not much is known about immigrant traders in the African craft market. The objective of this study was to investigate the process involves in the manufacturing and trading of woodcraft, stones carving and beads stores owned by immigrant traders. The study utilised a desk methodology to review literature in Green Market Square, Stellenbosch Craft markets, Hout Bay Craft Market and Franschhoek Craft market. The findings revealed that the art of wood carving uses cutting tools to make wooden figures, ornamental objects and sculptures. The beads are made of fine glass, broken and unusable bottles and other varieties of scrap glass. The finding also revealed that most craft businesses are seasonal the markets do not have shades and unpredictable weather pattern in Cape Town is also a problem, which limits growth prospects.The study recommended that policy makers should developed these markets.

  • Description: Photodynamic antimicrobial chemotherapy (PACT) is a well-known technique used against bacteria that have developed resistance towards antibiotics. We herein report the synthesis, photophysical properties, and PACT activity of 2-hydroxypyridine axial ligated indium 5,10,15,20-tetrakis-(4-phenylmethylthio) porphyrin (3) and quaternized 2-hydroxypyridine axial ligated indium 5,10,15,20-tetrakis-(4-phenylmethylthio) porphyrin (4). The porphyrin complexes (3 and 4) were further linked to oleyamine (OLM)/oleic acid (OLA) capped Ag/CuFe2O4 and also 6-mercapto-1-hexanol functionalized (MCH-Ag/CuFe2O4) nanoparticles through silver - sulphur (Ag-S) and silver-nitrogen (Ag-N); self-assembly. The PACT studies were carried out using Staphylococcus aureus. While all the synthesized porphyrins demonstrated PACT activity, the quaternized complex and its conjugate showed the highest PACT activity with 0% cell viability after irradiation for 25 min, resulting in a log reduction of 8.31.

  • Description: This study was undertaken in the South African higher education system in which the differentiation of institutions still reflects racial inequalities from the country’s history of colonial apartheid. As an educator in an institutional type referred to as Universities of Technology, I had become increasingly concerned about who succeeds, how they succeed, who fails, and who drops out. The South Africa education system broadly suffers from low student retention and high drop out with lower success rates mostly affecting Black students. By the end of apartheid in 1994, Black students had been entering Technikons en masse and were the dominant student group in these institutions which changed designation to Universities of Technology in 2005. Technikons offered programmes with a stronger technological and vocational orientation focusing on qualifications directly linked to the job market. They did not offer postgraduate programmes and today, Universities of Technology still produce little research. These institutions also battle with a far lower throughput rate than Traditional Universities and a higher graduate unemployment rate. This has led to a call for better theorised accounts of applied knowledge to replace unhelpful common-sense understandings. There was thus a call in the literature for studies, such as this one, that focused on the nature of knowledge in a diploma curriculum. Furthermore, the field of Marketing is under-researched. The field of Marketing has been characterised as having a weak theoretical foundation and as appropriating knowledge from other fields without growth of the field per se. In Marketing, importance is placed on the possession of a broad spectrum of general knowledge, rather than specialised accounts of the field. The study sought to examine the following research questions: 1) What kind of knowledge is privileged in the Marketing diploma? 2) How does the positioning of actors in the field of Marketing education impact on the choice and structure of knowledge privileged in the curriculum? The study was undertaken mainly through the use of interviews to explore academics’ perspectives on what is valued in the Marketing curriculum. Thirty-one academics from 11 institutions participated in the study. I also analysed course guides and other documentation related to the curriculum. The study analysed the organising of knowledge in the Marketing curriculum. To do this, the study drew on Legitimation Code Theory and in particular the tools of Specialisation and Semantics. These tools allowed the analysis of data to establish the basis on which it is specialised from other fields and the extent to which the field is contextually or conceptually coherent. The data demonstrated that academics who lecture in Marketing entered Marketing education from a diverse range of disciplines. The data also confirmed, in line with the literature, that the field of Marketing draws from multiple disciplines and fields for the purposes of serving the world of work. In Bernsteinian terms the nature of the Marketing curriculum is identified as a ‘region’. However, the data also demonstrated that the field of Marketing serves a heterogenous world of work characterised by constant changes which do not seem to allow a stable development of the field. The field of Marketing was thus portrayed as a region tending towards a generic, raising questions about the reliability of its knowledge base. The nature of generics often leads to an openness which is associated with instability, a weaker autonomy, and an inability to differentiate the field from others with further implications that knowledge in the curriculum is likely to be unsettled. One of the key findings was that while there was significant focus on knowledge, this was not the main basis on which success is achieved. Despite the ample evidence of knowledge in the Marketing curriculum, there was little agreement as to what constituted that knowledge, the actual nature of that knowledge was not settled, broadly agreed upon, nor particularly complex, drawing as it did on ‘everyday’ understandings of the world. The data revealed that there was little evidence that the knowledge was particularly specialised nor that it allowed for cumulative acquisition of ‘powerful knowledge’. Rather, the knowledges in the field of Marketing were characterised by a horizontal knowledge structure consisting of a set of languages acquired separately. The knowledges were based on different and sometimes even contradictory assumptions and thus presented few opportunities to integrate previous theories to build a more powerful knowledge structure. The knowledges tended to be context specific as opposed to being abstract or conceptual. There are social justice implications for fields in which the acquirer is only afforded context specific knowledges and as such has to acquire an endless series of low-level knowledges. They are not given access to powerful knowledge characterised by induction into a system of meaning which enables a more meaningful engagement with the complex world and thinking the not yet thought. In such instances, the education arguably does not provide access to the kind of specialised knowledge which allows for powerful meaning making in the world. The study calls for a strengthening of the epistemic spine of the Marketing diploma to provide access to more abstract, principled knowledge. A major finding was that most of the lecturers’ responses focused on the need for being a particular kind of knower to be successful in Marketing. The kind of person valued in Marketing was portrayed as possessing a particular personality and natural talent which were rarely seen as dependent on the knowledge acquired during the diploma, but rather on the dispositions that students brought. The respondents also mostly raised concerns that most of the students enrolled in Marketing did not to have the requisite ‘Marketing personalities’. Students were expected to be from a particular social class intimated through reference to their backgrounds, the schools they went to, their access to technologies, and the geographical regions they came from. They were expected to bring a particular language competency. Social class and language were arguably also used as coded reference to racial category, and this was more explicitly indicated by some respondents. The dominance of the knower in the data revealed that in Marketing, “you either have it or you don’t” indicating a strong view that Marketers are born with the necessary inherent characteristics of “confidence and people-skills” or belong to the social group that develops them. The implications were that if you do not have it, there is nothing one can do to get . This particular finding raises serious social justice issues on access and success in Marketing. If there is nothing that can be done to develop these characteristics, allowing such people into Marketing is setting them up for failure. On the other hand, denying access based on birth and social grouping raises concerns of the justice in the societies we live in. The study calls for an explicit engagement with the assumptions about the knower’s dispositions. While it was consistently evident that such dispositions were key to the specialisation of the field, the assumption that students either had these dispositions or lacked them is a social injustice and raises a number of unanswerable and painful questions given the racially differentiated success rates. The study concludes by calling for academics to explicitly curriculate for the target dispositions so that students are exposed to the value of these dispositions and given opportunities to engage with them.

  • Description: Euphorbia grandicornis Blanc is widely utilized in traditional medicine for a variety of ailments including body pains associated with skin irritations, inflammation, and snake or scorpion bites. Compounds from E. grandicornis were characterized using spectroscopic techniques, NMR, IR, MS, and melting points and alongside the extracts were evaluated for in vitro anticancer activity against several cancer cell lines. The root extract afforded known, β-glutinol (1), β-amyrin (2), 24-methylenetirucalla-8-en-3β-ol (3), tirucalla-8,25-diene-3β,24R-diol (4), stigmasterol (5), sitosterol (6), and hexyl (E)-3-(4-hydroxy-3-methoxyphenyl)-2-propenoate (7) based on their NMR spectroscopic data for the first report in E. grandicornis. The extracts and isolated compounds were evaluated for anticancer activities against hormone receptor-positive breast cancer (MCF-7), triple-negative breast cancer (HCC70), and non-tumorigenic mammary epithelial (MCF-12A) cell lines. The CH2Cl2 extract exhibited potent, cytotoxicity against MCF-7, HCC70, and MCF-12A cells. The aerial extract exhibited IC50 values of 1.03, 0.301, and 1.68 µg/mL, and root extract displayed IC50 values of 0.83, 0.83 and 3.98 µg/mL against MCF-7, HCC70, and MCF-12A cells respectively. The root extract thus showed selectivity for the cancer cell lines over the non-cancerous control cell line (SI = 4.80). Hexyl (E)-3-(4-hydroxy-3-methoxyphenyl)-2-propenoate (7) showed significant activity with IC50 values of 23.41, 29.45 and 27.01 µM against MCF-7, HCC70 and MCF-12A cells respectively, suggesting non-specific cytotoxicity.

  • Description: South Africa is on track to attaining the 2030 Agenda on reducing under-five deaths to 25 deaths per 1000 live births at its current momentum, however an unacceptable amount of infants are still at risk from preventable illnesses. Malnutrition is the major underlined cause of infant mortality rates in South Africa. Exclusive breastfeeding rates are low nationwide due to low exposure to breastfeeding information, some mothers having other commitments and others having breastfeeding difficulties. Implementation and expansion of simple, cost-effective interventions, such as exclusive breastfeeding for six months to reduce and/or prevent infant mortality rates, remains low in South Africa. The aim of the study was to determine one infant health issue of major concern to participants in two rural villages in the Eastern Cape, namely Glenmore and Ndwayana. The identified infant health issue was used to design an educational intervention in the villages. This was the second phase of this study. A community-based participatory approach was utilized in which the Angus Gillis Foundation, a non-profit organization that works in these communities, was one of the stakeholders. Stock status of WHO priority medicines for infants, semi-structured interviews and focus group discussions were carried out during the baseline study. The intervention phase contained pre-2 intervention semi-structured interviews with ten pregnant women followed by an educational intervention with nine out of the ten; and finally, a post-intervention with seven out of the ten women. A questionnaire was completed by members of the Angus Gillis Foundation to provide feedback on the sustainability of the intervention. Semi-structured interviews revealed that medicines stocked at the clinic parallel those indicated in the WHO priority medicines list for infants. The results from the focus group discussions indicated that mothers do not exclusively breastfeed their infants during the first six months. Pre- and post-intervention results on exclusive breastfeeding illustrated a positive change in participants’ knowledge and intent to breastfeed exclusively for six months. They showed a better understanding of the importance of exclusive breastfeeding and indicated a more focussed intention and confidence to carry out optimal breastfeeding practices. In the questionnaire the members of the Angus Gillis Foundation stated that the intervention is sustainable as it was linked with the existing networks. These include educational programs carried out in the villages by the foundation together with positive health champions, community health workers and women self-help groups; which will be able to build on the present knowledge base. Finally, the study also included the design of a booklet on the identified infant health issue. In conclusion, participants highlighted lack of understanding regarding breastfeeding as an issue of concern during the baseline phase of the study. This community-based educational intervention improved the understanding of breastfeeding among the participants, resulting in a positive change in perception with regards to exclusive breastfeeding practices.
