Online Self-Coaching Programme to Enhance Employability of Social Work Students
Authors: Botha Petro , Dykes Glynnis
Published: August 2020

In view of an increase in access to tertiary education and intense competition among graduates to find jobs in the labour market, the questions, “Who is responsible for ensuring the employability of students?” and “How can the employability of students be improved?” are of paramount importance. This article endeavours to answer these questions by focusing on the part that students themselves can play. An online self-coaching programme is introduced as an alternative strategy for enhancing the employability of social work students. The experiences of students from residential learning (RL) and open distance e-learning (ODeL) contexts who participated in a pilot study in South Africa are presented. The self-coaching programme is based on research conducted on the support needs of social work students using the Intervention Design and Development Model of Rothman and Thomas. Two online versions of the programme emerged and were piloted as part of content preparation by 10 social work students in two universities in South Africa, representing ODeL and RL contexts. A qualitative approach and purposive sampling were employed in the study. The data were analysed using the eight steps formulated by Tesch. The participants averred that the online self-coaching programme could be used effectively to facilitate social work students’ academic, professional and personal development, and to prepare them for employment in a competitive labour market.
Disclosing Child Sexual Abuse during Forensic Assessments of the Black South African Child
Authors: Rapholo Selelo Frank , Makhubele Jabulani
Published: August 2020

Child sexual abuse is a social and health issue that affects citizens across the globe. It has a number of physical, psychological and emotional consequences. Children are reluctant to talk about their involvement in sexual abuse owing to various reasons. Therefore, forensic interviewers need to understand the process of disclosure when conducting forensic assessments. They also need to be watchful of various dynamics that are likely to have an impact on the disclosure rate. The aim of this study was to describe the dynamics during forensic assessments in the context of the black South African child when disclosing child sexual abuse. A descriptive design using stratified random, purposive and convenient sampling techniques to select the participants was employed, resulting in 14 participants (13 were females and only one was male). The data were collected by means of semi-structured in-depth interviews and were thematically analysed using the Nvivo program. The findings reveal that personal characteristics of the child and the interviewer, their communication abilities, blind assessments and informed allegation interviews have an impact on forensic assessments of black South African children. It is concluded that the dynamics of disclosing child sexual abuse during forensic assessments in terms of the variables of the study are not unique, except in terms of sociocultural value systems, beliefs and customs. As a result, it is recommended that the forensic interviewers come to the developmental level of the child, speak his/her language or use translators for him/her to understand, and to follow blind assessments interviews as opposed to informed allegation interviews. However, informed allegations interviews are recommended when assessing very young children.
Social Workers’ Experiences of Psychological and Physical Violence at the Workplace
Authors: Malesa Kgashane Johannes , Pillay Roshini
Published: August 2020

Physical and psychological workplace violence perpetrated against social workers by clients and their acquaintances is a global reality. However, it is rarely discussed as social workers are trained to be client-centred, meaning that they prioritise the care and well-being of others above all else. In South Africa, the awareness of, and academic interest in, workplace violence and aggression are growing, particularly because employees are experiencing increased psychological distress and frustration. Despite this, there remains a dearth of research that investigates workplace violence perpetrated against social workers by clients. This qualitative study explored the experiences of 15 social workers and 3 key informants regarding workplace violence at a South African State Department in the Limpopo province. The study used interviews guided by a semi-structured interview schedule. Purposive sampling was used, and data were analysed using a thematic content analysis. The findings reveal that the participants understood the concept of workplace violence and had directly and/or indirectly been exposed to physical and more frequently psychological forms of workplace violence. Interventions and prevention mechanisms include increasing security in workplaces, training, counselling and education on workplace violence.
Social Workers’ Reflections on Utilising Indigenous Games in Child Counselling
Authors: Mthembu Maud , Mkhize Nozuko
Published: August 2020

This paper reports on the adaptation of local indigenous children’s games in South Africa that can be integrated during child counselling. There is a plethora of literature that advocates for the reconceptualisation of social work in non-western societies to align it with the values of clients being served. However, there is a dearth of literature on available indigenous social work games that can be applied particular in child counselling. Using a qualitative design, six social work practitioners, purposively sampled, were individually interviewed to explore their integration of indigenous games during child counselling. The findings indicate that through reflexivity, social workers learn and observe context-relevant knowledge from the communities they serve and that accumulated knowledge informs innovative practice interventions in social work. In this paper, children’s social background, culture, play behaviours and community assets informed social workers’ choice of the games they could incorporate in child counselling. The integration of local games, such as Uchiki, Umangqalutye, Eight Stones and riverbank clay, in child counselling sessions promotes a sense of mutual learning that benefits the helping profession to deliver a context-relevant service.
Non-Governmental Organisations as Stakeholders in the Implementation of Community-Based Research by Universities
Authors: Schiller Ulene , De Wet Gideon
Published: August 2020

Numerous research studies are conducted in communities surrounding universities. This paper illustrates the value of non-governmental organisations (NGOs) in South Africa as stakeholders in an intermediary platform that can contribute to community development, based on research done by university researchers in these communities. The Quintuple Helix Model was used as a theoretical premise, viewing the importance of collaborative partnerships to contribute to sustainable development. The orientation enhanced in this paper is that research findings obtained from communities, in combination with the shared speciality areas and expertise of stakeholders such as NGOs, would serve as dynamic catalysts to bring stakeholders and researchers together in an innovative intermediary platform context that can facilitate development. A triangulation mixed-method design was used where a focus group discussion was held with 19 participants from NGOs, augmented by an open-ended questionnaire. The results indicated that NGOs can be viewed as strategic partners in community development and indicated how they could contribute in facilitating the implementation of research recommendations done by university researchers. NGOs are responsive to the needs and welfare of the people of South Africa supporting participatory democracy.
Barriers to Postgraduate Qualifications among Social Workers
Authors: Mmadi Pontsho James , Sithole Sello Levy
Published: August 2020

This article describes factors that militate against social workers’ endeavours to undertake postgraduate studies. The study adopted a qualitative research paradigm, where a sample of 10 participants was interviewed at Driekop in the Limpopo province of South Africa. The Maintaining Professional Competence model guided the study. A content thematic analysis was used to make sense of the findings. The findings demonstrate that social workers’ aspirations to further their studies beyond their bachelor’s degrees are constrained by impediments, such as a lack of motivation, the poor image of the profession, heavy workloads, family commitments, financial constraints, and poor scholarly habits. Recommendations are suggested to deal with the barriers that surfaced.
Human Rights Education in Social Work in Africa
Authors: Giliomee Corlie , Lombard Antoinette
Published: August 2020

Social work is a human rights profession and assumes that human rights are embedded in social work practice and education. However, in Africa where human rights violations are rife, with severe implications for social work practice and education, thus far, a human rights focus in social work education has not yet received the attention it deserves. A critical analysis of human rights education in social work in Africa in the context of decolonisation and development shows the interrelatedness of human rights and human development, which, in turn, informs the learning content of the social work curriculum and pedagogy of human rights in social work. Social work educators in Africa are encouraged to take up the challenge of adopting and integrating a pedagogy that will fast-track the infusion of human rights values in the social work curriculum.
The Way in Which Child and Youth Care Workers in South Africa Cope with Psychosocial Challenges
Authors: Molepo Lesiba Phineas
Published: August 2020

Child and youth care workers deal with the psychosocial challenges experienced by young people in their care and may as a result themselves experience stress, anxiety and depression. This paper explores the psychosocial challenges experienced by child and youth care workers in South Africa, and the coping strategies that they apply. A collective case study design within a qualitative approach was used. Purposive sampling was used, with the sample consisting of 93 participants from government and non-governmental organisations based in rural, semi-urban and urban areas across the six provinces of South Africa. An interview schedule was designed to collect qualitative data from 11 focus group interviews. Data analysis was divided into data reduction, data display, and drawing and verifying conclusions. Psychosocial challenges identified by the participants were the inability to disengage from the work environment, disengagement from social activities, personal trauma, invasion of personal boundaries, and emotional well-being issues. The following broad coping strategies were identified: non-existent coping mechanisms, personal missions, substance abuse, withdrawal, and thoughts of quitting. Child and youth care workers experience a range of psychosocial challenges but have established a range of mostly adequate and contextually relevant coping strategies. The paper recommends that child and youth care workers find a healthy balance between their personal and professional life, timeously seek psychosocial support, and keep on developing themselves to acquire skills that will enhance their practice and broaden their scope of practice.
Compassion Fatigue and Resilience among Child Protection Service Workers in South Africa
Authors: Campbell Emma Janet , Holtzhausen Leon
Published: August 2020

The aim of this quantitative, inferential research was to investigate how working with vulnerable and abused children and families has an impact on child protection service workers in South Africa. In particular, the study explores whether such work leads to compassion fatigue, and whether there is a relationship between compassion fatigue and resilience. Compassion fatigue is recognised as a state of exhaustion that results in helping professionals losing their ability to empathise with their clients, while resilience refers to the process of adaptation in the face of adversity. Using availability sampling, online questionnaires were sent to child protection service workers at the “Afrikaanse Christelike Vrouevereniging”, a national child protection non-profit organisation. The questionnaire included the Professional Quality of Life Scale that measures compassion fatigue, and the Brief Resilience Scale that measures one’s ability to bounce back from stress or adversity. The responses of 81 child protection service workers who completed the questionnaire were captured and analysed using the Statistical Package for the Social Sciences. The results of this research showed that the participants are impacted by their work in the field of child protection and are vulnerable to compassion fatigue. Furthermore, the results showed a relationship between the Brief Resilience Scale and the Professional Quality of Life Scale, i.e. when the participants’ resilience scores were higher, compassion fatigue scores tended to be lower.
In Silico Probing Ca2+ and Zn2+ Permeable Transmembrane 4Aβ1-42 Barrel
Authors: Ngo Son Tung
Published: August 2020

Alzheimer’s disease is known as one of the most popular forms of dementia affecting numerous people worldwide. The Amyloid beta (Aβ) peptides form to oligomeric conformations that cause the intracellular Ca2+ and Zn2+ abnormality leading to the death of neuron cells. The failure of AD therapy targeting Aβ oligomers probably caused by misunderstanding the ions transport through transmembrane Aβ (tmAβ) ion-like channel since Aβ oligomers transiently exist in a mixture order of Aβ oligomers. The high-resolution of tmAβ peptides are thus unavailable until the date. Fortunately, computational approaches are able to complement the missing experimental structures. The transmembrane 4Aβ1-42 (tm4Aβ1-42) barrel, one of the most neurotoxic elements, was thus predicted in the previous work. Therefore, in this context, the Ca2+/Zn2+ ions transport through the tm4Aβ1-42 barrel was investigated by using the fast pulling of ligand (FPL) and umbrella sampling (US) methods. Good consistent results were obtained implying that Ca2+ ion transport through tm4Aβ1-42 barrel with a lower free energy barrier compared with Zn2+ ion. The obtained results about Ca2+/Zn2+ transport across tmAβ1-42 barrel probably enhances the AD therapy.

Published: August 2020

Variation in the metal centres of M-M paddle-wheel SBU results in the formation of isostructural DUT-49(M) frameworks. However, the porosity of the framework was found to be different for each of the structures. While a high and moderate porosity was obtained for DUT-49(Cu) and DUT-49(Ni), respectively, other members of the series [DUT-49(M); M= Mn, Fe, Co, Zn, Cd] show very low porosity and shapes of the adsorption isotherms which is not expected for op phases of these MOFs. Investigation on those MOFs revealed that those frameworks undergo structural collapse during the solvent removal at the activation step. Thus, herein, we aimed to study the detailed structural transformations that are possibly occurring during the removal of the subcritical fluid from the framework.

Authors: Meena Shamrao Deogade
Published: August 2020

Ayurveda always recommended the holistic approach for the prevention of diseases, health promotion and curing the ailments. Agnihotra/Yagya/ homa is a part of Indian rituals, and one of the ancient therapy of healing recommended by Ayurveda. An agnihotra is a simple form of homa. Various materials are used in this therapy like cow dung cake, rice, ghee and medicinal plants either as a firewood or Samidha, which are helpful for purification of the atmosphere resulting in prevention and control of various communicable diseases. In Ayurveda epidemic or pandemic has been described as Janapadodhwansa Rogas. And causative factors mentioned that vitiation of Vayu (air), Jala (water), Desh (area), and Kala (season). Abhishyangaja (effects of pathogens, evil forces and unhygienic condition) is also one of the causes of epidemic/ pandemic. For this reason, Ayurveda advocated sterilization of water, air, soil and atmosphere with the help of Agnihotra, i.e. Homa, Yagya, Dhupana. As Agnihotra is applied in Ayurveda for therapeutic purpose is also known as Homa therapy. Many studies showed the antimicrobial activity of smoke raises from Agnihotra. When the whole world is facing the pandemic Coronavirus disease (COVID-19), need to think about this therapy. According to world meter, there are 1,853,155 cases, 114,247 deaths till 13 April 2020. Hence it is the right time to think about the control and preventive measures of the infectious agent (SARS-Cov-2) of COVID-19 disease with the help of Agnihotra/Homa therapy.

ABSTRAKSalah satu faktor penyebab kecelakaan yang signifikan adalah tidak sesuainya kecepatan kendaraan dengan kondisi jalan, lingkungan dan kegiatan, dalam hal ini adalah kecepatan yang terlalu tinggi. Jalan tol/jalan bebas hambatan merupakan salah satu jalan yang berpotensi memiliki banyak pelanggaran dalam kecepatan kendaraan. Batasan kecepatan jalan tol telah di atur dalam PM Hub 111/2015 yaitu 40 km/jam untuk tol dalam kota dan 60 km/jam - 100 km/jam untuk tol luar kota. Untuk memastikan kecepatan rata-rata kendaraan dan menentukan tingkat pelanggaran kendaraan yang melintasi ruas jalan tol Cipularang maka penelitian menggunakan metode pengumpulan data primer/pengamatan secara langsung. Hasil analisis secara keseluruhan didapatkan bahwa rata-rata kecepatan kendaraan mobil penumpang sebesar 88 km/jam, truk 62 km/jam dan bus 72 km/jam dengan persentasi kecepatan rata-rata untuk mobil penumpang, truk dan bus berturut-turut sebesar 43%, 5% dan 22%. Hal ini menunjukan terdapat pelanggaran batas kecepatan maksimum untuk kendaraan mobil penumpang dengan prosentase yang tinggi (lebih dari 30%) atau kecepatan rata-rata lebih dari 80 km/jam.Kata kunci: kecelakaan, batas kecepatan, jalan tol ABSTRACTOne factors of a significant accident is not according to the speed of the vehicle with the environment, environment and activities, in this case the speed is too high.
