Product development within the framework of a National Casting Technology Centre

Published ArticleThe need for a state of the art advanced National Casting Technology Centre (NCTC) has been widely supported throughout industry and recognised as an important facilitator in the growth of the foundry industry. This initiative also aligns itself with the government's Advanced Manufacturing Technology Strategy (AMTS), which is an implementation strategy in support of the South African government's Integrated Manufacturing Strategy (IMS) and National R&D Strategy (NRDS). The AMTS aims at supporting and developing the downstream high technology manufacturing industry, inter alia through the aerospace, automotive and metals sectors. In light of the above and in an effort to retain and expand the current national skills, expertise and facilities in advanced casting technologies, the National Product Development Centre at the CSIR has initiated a process of establishing a National Casting Technology Centre (NCTC). The establishment of the NCTC provides a supportive technology platform for the Advanced Metals Initiative (AMI), which was launched in 2003. The primary objective of the NCTC is to preserve and expand the national expertise and capabilities in cast metals manufacturing by supporting the local casting industry with process development, technology transfer and skills enhancement in order to increase their global competitiveness

Die potensiële waarde van gesinsrituele vir betekenisgewing deur kinders

The potential value of family rituals in children’s processes of meaning making This article reports on the findings of a qualitative study that explored family rituals as potential asset in children’s processes of giving meaning. As such, the purpose of the study was firstly to identify the dimensions of family rituals in one family that participated; and secondly, to explore potential ways in which the participation in family rituals could influence children’s processes of meaning making. The study was embedded in the interpretivist paradigm, rested on an instrumental case study design, and deployed educational psychological assessment, informal conversations, semi-structured interviews, reflective journals, visual data, observation and field notes as data collection and documentation methods. Two Afrikaans-speaking primary school children (a brother and sister) and their parents were purposefully selected as participants. During the study, the five basic dimensions of family rituals (structure, meaning, persistence and commitment, adaptability and gender relations) could be identified in the rituals practised by the participating family. In addition, six other dimensions were prominent, namely task completion, communication, roles, affective management, affective involvement and behaviour management. Based on the positive effect of family rituals on the meanings given by the participating children it is concluded that family rituals may serve as an asset within the family context and as such be employed during family intervention initiatives

The original publication is available at http://www.sajip.co.zaCITATION: Visser, E.M., Du Preez, R. & Du Toit, J.B. 1996. The mature female clothing shopper : profiles and shopping behaviour. SA Journal of Industrial Psychology, 22(2):1-6, doi:10.4102/sajip.v22i2.603.This study was designed to profile the mature female clothing shopper. More specifically certain variables that could be attributed to differences in consumer behaviour were investigated. Mature female clothing shoppers were segmented as clothing moderates, clothing enthusiasts and the clothing unconcerned. These three cluster groups significantly differed regarding clothing involvement, clothing orientation, activities, interests, opinions, family orientation, needs and media usage. No significant differences were found among the three groups regarding evaluative criteria for clothing and clothing store attributes. Profiles of the clusters were developed, along with applicable marketing implications. Recommendations for further research are made.Hierdie studie is onderneem ten einde die vroulike kledingverbruikers van 55 en ouer te tipeer.

Open set learning with augmented category by exploiting unlabelled data (open-LACU)

Considering the nature of unlabelled data, it is common for partially labelled training datasets to contain samples that belong to novel categories. Although these so-called observed novel categories exist in the training data, they do not belong to any of the training labels. In contrast, open-sets define novel categories as those unobserved during during training, but present during testing. This research is the first to generalize between observed and unobserved novel categories within a new learning policy called open-set learning with augmented category by exploiting unlabeled data or open-LACU. This study conducts a high-level review on novelty detection so to differentiate between research fields that concern observed novel categories, and the research fields that concern unobserved novel categories. Open-LACU is then introduced as a synthesis of the relevant fields to maintain the advantages of each within a single learning policy. Currently, we are finalising the first open-LACU network which will be combined with this pre-print to be sent for publication.Comment: 11 Page

Socio-demographic insights into South African student drinking behaviour

Hazardous and harmful drinking is on the rise among adolescents and young adults and has been classified as a major health problem. University students is a subgroup of young adults that are characterised by more frequent, and even more dangerous drinking behaviours than their non-student peers and new intervention approaches are needed to foster behavioural change. The purpose of this study is to investigate the drinking behaviour and socio-demographic profile of a cohort of South African university students and propose future research avenues to address student drinking behaviour. Ex post facto survey data was collected by means of a questionnaire including the Alcohol Use Disorder Identification Test (AUDIT) and a demographic section. Data was gathered from university students (n=474) from a single campus within South Africa. Data analysis included descriptive statistics, reliability analysis, independent sample t-tests and one-way ANOVAs. Results indicate significant differences in drinking behaviour for gender groups; age; level of disposable income; type of beverage consumed, binge drinking, level and frequency of consumption. The findings have implications for higher education management, public health authorities, and academia and provide valuable insight on the socio-demographic profile and drinking behaviour of a cohort of university students. The findings serve as a foundation for future research into the development of a persuasive communications strategy (educational and prevention campaigns) that could foster much needed behavioural change

Orthopaedic referrals using a smartphone app: Uptake, response times and outcome

Background. It is well established that South Africa (SA) suffers an immense burden of violence and injuries. The responsibility of providing care for these injuries falls mainly on public health services, resulting in overloading of the health system. Prior to a recent intervention, the large burden had been exacerbated by limitations in the traditional referral system that highlighted the need for a better referral system. Vula’s smartphone app was introduced at Tygerberg Hospital in August 2016. This study evaluated the uptake, response times and outcomes using this app.Objectives. The main objectives of the study were to describe: (i) the number of referrals; (ii) referral response times; (iii) referring facilities; and (iv) referral outcomes. Secondary objectives were to: (i) evaluate whether the referral outcome pathway was appropriate; and (ii) assess professional conduct and evidence of upskilling.Methods. This retrospective, descriptive study investigated Vula app referrals to the Division of Orthopaedic Surgery at Tygerberg Hospital between 1 August 2016 and 31 March 2017. Vula was advertised to key facilities in the hospital’s referral network. All referrals to the division during the study period were systematically included in the analysis of operational outcomes, although some were excluded from the subsequent referral outcome analysis. Operational outcomes included the number of referrals, referring facilities and referral response times. Referral outcome analysis included the clinical diagnosis, referral pathway, whether the referral was used for upskilling and whether it was conducted in a professional manner.Results. A total of 2 275 referrals from 39 different facilities were received during the study period from 238 individual users; 50% of referrals received a response within 11 minutes, while a small percentage received no response. Clinical and demographic characteristics of 1 985 patients included in the referral outcome analysis indicated that the majority of trauma and emergency referrals involved males, with closed fractures being the most frequent clinical presentation. Although the most common referral outcome was immediate transfer, one-third of the patients were treated at the referring hospital with advice only.Conclusions. The large volume of orthopaedic referrals received through the Vula app suggests that Vula represents a successful alternative to traditional referral methods. Referrals managed by advice only could suggest that Vula facilitates some relief for the overburdened trauma services. Future research could further explore Vula’s role in strengthening the public health system, including interventions for high-volume referral areas and upskilling of referring health workers.

A guiding framework for the development of a trans-disciplinary community mental health student teaching and learning platform

Establishing a trans-disciplinary mental health platform could contribute to outreach and service training agendas in a higher educational context. The purpose of the platform described in the article provides an opportunity for students to learn from each other, with each other and about each other, across a variety of disciplines in one university, while also effectively addressing the needs of the surrounding community. This article records the background to the establishment of a unique multi-disciplinary university-community collaborative initiative in South Africa by using a self-reflective, action research approach. It also identifies lessons learnt and creates a guiding framework for the establishment of similar projects in other communities. It contributes firstly, to provide a framework to guide and encourage future establishments of similar university-community collaborative engagement endeavors and, secondly, to highlight the requirements for sustaining services to communities when senior students exit their university programmes, while new students enter

Tuberculous meningitis in children: reducing the burden of death and disability

Tuberculous meningitis disproportionately affects young children. As the most devastating form of tuberculosis, it is associated with unacceptably high rates of mortality and morbidity even if treated. Challenging to diagnose and treat, tuberculous meningitis commonly causes long-term neurodisability in those who do survive. There remains an urgent need for strengthened surveillance, improved rapid diagnostics technology, optimised anti-tuberculosis drug therapy, investigation of new host-directed therapy, and further research on long-term functional and neurodevelopmental outcomes to allow targeted intervention. This review focuses on the neglected field of paediatric tuberculous meningitis and bridges current clinical gaps with research questions to improve outcomes from this crippling disease
