An Exploration of Violent Behaviour of Young Ex-Offenders on the Cape Flats, South Africa: Suggestions for Youth Work Practice
Authors: Chauke Thulani Andrew , Malatji Khashane Stephen
Published: September 2022

The purpose of this study was to investigate factors that contributed to violent behaviour among young ex-offenders, and the challenges that young ex-offenders faced when reintegrating into mainstream society on the Cape Flats in South Africa. The researchers used a qualitative approach grounded in phenomenology as the research design. The study population consisted of eight young ex-offenders on the Cape Flats who had served sentences in prison. Purposive sampling was used to select them for participation. The data were collected through individual semi-structured interviews and a phenomenological analysis was used to analyse the participants’ responses. Ethical considerations such as informed consent, privacy, voluntary participation, and confidentiality were given due attention in this study. The results of the study revealed that factors such as the lack of parental affection, peer pressure, the use of drugs, and domestic violence contributed to violent behaviour among young ex-offenders on the Cape Flats. The study concluded that, when returning to the community, young ex-offenders face challenges such as family and community mistrust and a lack of employment opportunities. The study recommends the involvement of all young ex-offenders in activities of the National Youth Service, fully supervised by the National Youth Development Agency and officials of the Department of Correctional Services for a certain period as part of youth work practice in South Africa.
Understanding Social Workers’ Well-Being through Their Valued Aspirations
Authors: Mseba Precious
Published: September 2022

Recent studies across various contexts have shown that social workers’ well-being or lack thereof affects their ability to advance social well-being. This is even more marked in a context such as South Africa in which social workers often function with very few resources and in contexts of extreme poverty. Using the capability approach, this qualitative study deals with the question of social workers’ well-being. It focuses on social workers’ aspirations, the ideals to which they aspire as a window to understanding their well-being as professionals. Drawing from interviews with practising social workers and social work students from a South African university, the study (a) examines social workers’ understanding of professional well-being, (b) identifies social workers’ aspirations and their connection to well-being achievement, and (c) outlines the necessary opportunities for the achievement of social workers’ valued aspirations. By paying particular attention to social workers’ aspirations, this article proposes a much broader understanding of social workers’ well-being than is possible when we focus on individual aspects of professionals’ well-being such as physical health or positive psychological functioning. The findings suggest that, apart from physical and emotional wellness, social workers understand their well-being in terms of achieving their valued aspirations, namely, effective helping, professional growth, personal growth, and material achievements. The study identifies several capabilities necessary for social workers’ professional well-being.
Guidelines for Supporting a Community of Inquiry Through Graded Online Discussion Forums
Authors: Mudau Patience Kelebogile , van den Berg Geesje
Published: September 2022

Online courses have risen in popularity over the last few years, mainly because of the convenience of studying from anywhere and at a time that is suitable for students. The Covid-19 pandemic has made online courses a convenient way to learn in a safe environment. Online environments that can instil a strong sense of community therefore need to be created to support students adequately. One way to create such an online learning community is to engage students in online asynchronous discussions. The purpose of this paper, therefore, will be first to determine successful strategies and the value of online discussions from the previous research literature. Second, we will report on our research findings and provide guidelines for designing online graded discussions that support a community of inquiry. We will employ the Community of Inquiry framework to conceptualise the community in online discussions. In the research, we will use a qualitative approach to collect data within an interpretative paradigm. The context of this study is a structured online master’s programme offered at an open distance e-learning institution. It is envisaged that the insights from this research would guide facilitators in selecting suitable strategies when designing online graded discussions. Graded online discussions have the potential to encourage student engagement and to create an online learning community if they are designed to encourage social, cognitive and teaching presences.
Digital Literacy: An Investigation into Perceived Competencies of Open Distance Learning Students in the Eastern Cape Province of South Africa
Authors: Daya Raseela
Published: September 2022

The aim of this study was to investigate and describe the perceived digital literacy competencies of open distance learning students at the University of South Africa in the Eastern Cape province of South Africa. In this study, I examined whether there is a statistically significant relationship between the independent variables, attitudes towards digital technology for academic purposes, use of the Learner Management System, attendance at regional digital literacy workshops, and the dependent variable, perceived digital literacy competencies. In this study, I employed the new conceptual framework of e-skills for digital inclusion by Pokpas to investigate the perceived digital literacy competencies of the students. I used a quantitative research approach which is used to examine relationships between variables and statistical procedures to analyse the data. The study concluded that most students have high self-perceived digital literacy competencies. Statistically significant positive relationships were found between attitude towards digital technology for educational purposes, use of the Learner Management System, attendance at regional digital literacy workshops and perceived digital literacy competencies. Recommendations were made to revisit the marketing strategy, the offering of digital literacy workshops, and the admission policy and to include a digital literacy competency assessment test for all students. The study recommended further research to test the actual digital literacy competencies of the students, emphasising the importance for all students to be digitally literate. This is not only for achieving academic success but also for being able to operate effectively and efficiently in the digital society and being prepared for the 4IR.
Implementing Open Distance and E-Learning in Teacher Training Institutions in Eswatini
Authors: Madlela Benkosi , Ngakane Bonny
Published: September 2022

Technological advancement and the advent of the internet led higher education institutions to transform from open and distance learning to open distance and e-learning. The University of South Africa was the first university in Africa to offer distance education since 1946. Its success inspired other African countries such as Zimbabwe and Botswana that established open and distance learning universities. In Eswatini, the Ministry of Education and Training enacted an education policy that calls for the introduction of open and distance learning in all existing and new institutions of higher learning. The policy did not give guidelines on the ways in which institutions were to implement open and distance learning. In the interim Eswatini does not have a fully fledged open and distance learning university. We conducted the study to explore the ways in which teacher training institutions in Eswatini implemented open distance and e-learning under the prevailing circumstances. The findings revealed that the introduction and implementation of open distance and e-learning in teacher training institutions were reactive measures to mitigate the Covid-19 lockdown and restricted movements. We recommended that institutions use blended learning while building capacity to gradually introduce open distance and e-learning and train their students and staff on e-learning knowledge and skills. We also recommended that the Ministry of Education and Training enact a policy with guidelines and a framework for implementing open distance and e-learning, and that the government build an open and distance learning university to align with other countries.
Effects of pharmaceutical promotions on antibiotics prescribing behavior of Nigerian private medical practitioners
Authors: Offor Ifeanyichukwu , Abubakar Hadiza F. , Joda Arinola E.
Published: September 2022

Objectives:

About 80% of pharmaceutical marketing efforts are directed toward physicians who are important decision-makers to patients’ medication needs. Pharmaceutical marketing can affect drug prescriptions, which, in turn, may adversely impact prescription practices. This study investigated the effect of pharmaceutical promotions on the antibiotic prescribing behavior of private practice physicians.

Materials and Methods:

A cross-sectional and descriptive design was employed. Self-administered questionnaires, scaled on a linear 5-point Likert Scale, were distributed among 268 physicians attending the 44th annual scientific conference of the Association of Nigerian Private Medical Practitioners at Ibadan, in Southwest Nigeria.

Results:

The study achieved a response rate of 94%, and 243 completely filled questionnaires were included for data analysis using R version 4. Cronbach’s alpha reliability of the research instrument was found to be 0.991, indicating an excellent internal consistency. Most of the physicians were male (71%), medical officers (83%), and 49% were between the ages of 51 and 60 years. About 65% had over 20 years of practice experience. A majority, 211 (87%), have prescribed antibiotics under the influence of pharmaceutical companies’ promotions. However, Fisher’s exact tests demonstrated a weak association between relevant independent variables and the dependent variable (P > 0.05).

Conclusion:

Product detailing by pharmaceutical sales representatives was the most popular form of promotion and company-sponsored presentations had the greatest influence on the physicians’ prescription practice. It is, therefore, recommended that pharmaceutical promotions should be well regulated to guard against unethical practices.
Socially, Culturally and Spiritually Sensitive Public Health Palliative Care Models in the Lower-income Countries: An Integrative Literature Review
Authors: Laabar Tara Devi , Saunders Christobel , Auret Kirsten , Johnson Claire E.
Published: September 2022

The demand for palliative care (PC) is ever-increasing globally. The emergence of COVID-19 pandemic has further accelerated the need for PC. In the lower-income countries (LICs), where PC need is highest, PC, the most humane, appropriate and realistic approach to care for patients and families affected by life-limiting illness, is minimal or non-existent. Recognising the disparity between high, middle and LICs, the World Health Organization (WHO) has recommended public health strategies for PC within the socioeconomic, cultural and spiritual contexts of individual countries. This review aimed to: (i) identify PC models in the LICs utilising public health strategies and (ii) characterise how social, cultural and spiritual components were integrated into these models. This is an integrative literature review. Thirty-seven articles were included from a search of four electronic databases – Medline, Embase, Global Health and CINAHL. Literature, both empirical and theoretical literature, published in English from January 2000 to May 2021 that mentioned PC models/services/programmes integrating public health strategies in the LICs were included in the study. A number of LICs utilised public health strategies to deliver PC. One-third of the selected articles highlighted the importance of integrating sociocultural and spiritual components into PC. Two main themes – WHO-recommended public health framework and sociocultural and spiritual support in PC and five subthemes – (i) suitable policies; (ii) availability and accessibility of essential drugs; (iii) PC education for health professionals, policymakers and the public; (iv) implementation of PC at all levels of healthcare and (v) sociocultural and spiritual components, were derived. Despite embracing the public health approach, many LICs encountered several challenges in integrating all four strategies successfully.

Synthetic applications of photochemical decarbonylation of oxetanone and azetidinone
Authors: Singh Manvendra , Dhote Pawan , Boskovic Zarko
Published: September 2022

Previously unexplored decarbonylative photochemistry of 3-oxetanone and N-Boc-3- azetidinone is described. Dipoles derived from both compounds undergo [3+2] cycloaddition with a variety of alkenes to produce substituted tetrahydrofurans and pyrrolidines, respectively. The reaction has a sufficiently wide scope to produce scaffolds that were either previously inaccessible or difficult to synthesize, thereby providing experimental access to new chemical space.
Molecular Nanocomposites with Lanthanide- and Counter-Cation-Mediated Interfacial Electron Transfer between Phthalocyanine and Polyoxovanadate

Published: September 2022

A series of {V12}-nuclearity polyoxovanadate cages covalently functionalised with one or sandwiched by two phthalocyaninato (Pc) lanthanide (Ln) moieties via V−O−Ln bonds were prepared and fully characterised for paramagnetic Ln = SmIII–ErIII and diamagnetic Ln = LuIII, including YIII. The LnPc-functionalised {V12O32} cages with fully-oxidised vanadium centres in the ground state were isolated as (nBu4N)3[HV12O32Cl(LnPc)] and (nBu4N)2[HV12O32Cl(LnPc)2] compounds. As corroborated by a combined experimental (EPR, DC and AC SQUID, laser photolysis transient absorption spectroscopy, electrochemistry) and computational methods (DFT, MD, model Hamiltonian approach), the compounds feature intra- and intermolecular electron transfer that is responsible for a partial reduction at V(3d) centres from VV to VIV in the solid state and at high sample concentrations. The effects are generally Ln-dependent and are clearly demonstrated for the (nBu4N)3[HV12O32Cl(LnPc)] representative with Ln= LuIII or DyIII. Intramolecular charge transfer takes place for Ln = LuIII and occurs from a Pc ligand via the Ln centre to the {V12O32} core of the same molecule, whereas for Ln= DyIII only intermolecular charge transfer is allowed, which is realised from Pc in one molecule to {V12O32} core of another molecule usually via the nBu4N+ counter-cation. For all Ln but DyIII two of these phenomena may be present in different proportions. Besides, it is demonstrated that (nBu4N)3[HV12O32Cl(DyPc)] is a field induced single molecule magnet with a maximal relaxation time of order 10–3 s. The obtained results open up the way to further exploration and fine-tuning of these three-modular molecular nanocomposites regarding tailoring and control of their Ln-dependent charge-separated states (induced by intramolecular transfer) and relaxation dynamics as well as of electron hopping between molecules. This should enable to realise ultra-sensitive polyoxometalate powered quasi-superconductors, sensors and data storage/processing materials for quantum technologies.
A Rising New Start For Fergusson Park
Authors:   , Hanson James
Published: September 2022

The purpose of this research is to identify a solution for community facilities that are experiencing a growing number of users due to population increase, whilst simultaneously facing the future impacts of rising sea levels due to climate change.

This research was undertaken to find a solution so that community buildings can have a longer life and under-go an adaptive re-use should the implications of rising sea levels prohibit the current use from continuing.

This research will be carried out using the site example of Fergusson Park in Tauranga New Zealand, currently a sports focused community facility that will be underwater in 100 years. The method of this thesis will be to undertake different research techniques in order to uncover the best solution for Fergusson Park through designing a sports pavilion that rises with the sea so that when the sports fields are underwater, the building will have a future beyond the realm of sports.

This research is an accumulation of data that lead to one potential design solution that achieved the overall design goals. Through further development there is opportunity to increase the relationship between the natural environment and the built environment, where the design could actively combat climate change through people using the building.
Evidence and Being: The Metaphysics of Husserl's first four Cartesian Meditations
Authors:   , Wright James
Published: September 2022

This thesis examines the metaphysics of Edmund Husserl’s transcendental phenomenology. Specifically, I focus on Husserl’s ‘Cartesian way’ to phenomenology as it is presented in the first four Cartesian Meditations. In the first part of the thesis, I provide an account of Husserl’s concept of evidence, and detail how considerations of evidence lead Husserl to the methodological procedures known as the epoché and the transcendental reduction. These methodological procedures limit inquiry to the field of evidence-experience. I then provide an account of the method of phenomenological description, with a particular focus on the manner in which Husserl seeks to explain the ‘transcendence’ of the world from within the bounds of evidence-experience. In the second part of the thesis, I discuss how Husserl’s phenomenological methodology interacts with metaphysics, and argue that it cannot be understood as metaphysically neutral. It is also incompatible with both realism and correlationism. Finally, I argue that Husserlian phenomenology is most accurately categorised as a form of idealism.
EGYPTOLOGY: THE MISSING MİLLENNIUM: ANCIENT EGYPT IN MEDIEVAL ARABIC WRITINGS
Authors: KIRBAŞOĞLU Hayri
Published: September 2022

The Arab study of Ancient Egypt was the result of a universal understanding of history rather than the narrow purpose of verifying scriptures. They were critical of pre-Islamic written sources and did not accept even texts based on eyewitnesses uncritically. The Arabs' work, which included accurate descriptions of ancient monuments, was aimed at understanding their symbolic value and function. They noticed the relationship of the ancient Egyptian language to Coptic, the phonetic value of hieroglyphs, and that some were grouped like alphabets. Arab writers interested in deciphering Egyptian script were primarily alchemists and often Sufis. Access to Ancient Egyptian texts written in Demotic and Coptic – often in Greek translations – has helped Arab scholars better understand the complex nature of Egyptian religion.

Studies of the origin of Sufism tend to concentrate on India and Persia, without mentioning the Egyptian sources. However, for example, Akhenaten's comparison of Suhrawardi- Illuminationism (Ishraqiyya) with sun hymns and studies on Mandaeanist/ Sabianist religious traditions in Iraq and Iran will shed light on the similarities between Egyptian religion and especially rituals and beliefs.

Medieval writers tried to find common ground between Islamic teachings and Ancient Egyptian religion.

Studies of Arabic philosophy can shed light on the problems of Ancient Egyptian philosophy. Because some basic concepts of Ancient Egyptian philosophy formed the basis of later Arab and Greek philosophy. Arab writers, like their classical predecessors, thought that this country had been home to science and wisdom since Hermes of Egypt, to whom they attributed the invention of writing, alchemy and medicine. They knew that the pharaoh Moses was dealing with was not a typical pharaoh but an exception. Pharaohs were portrayed as skilled rulers, knowledgeable and pious figures who cared for the welfare of the people.

Cleopatra is described in Arabic sources as a philosopher and scholar, without reference to her physical attractiveness.

Despite more than two centuries of domination of Egyptology by the Eurocentric view that ignored the thousand-year Arab contribution, archaeologists working in other parts of the Near East have also begun to realize the problem of Western dominance among them. But we also owe much to our Western colleagues for their invaluable contributions.

Children’s speech innovations
Authors: Tseitlin S. N.
Published: September 2022

The difference between children’s and adults’ speech consists in unusual lexemes or forms of familiar words as well as non-standard meanings of common words occurring in the former. The term error is not appropriate for such cases since these are legitimate elements of the child’s emerging language system. Despite their uniqueness, they do not hinder children’s communication with grown-ups. These units violating the linguistic norm are called innovations. The analysis of children’s innovations enables linguists to explore the nature of language rules and their hierarchical structure as well as to identify accidental gaps (or lacunae) in the language. The article presents a typology of children’s speech innovations from the standpoint of the language norm.
