An evaluation of the Contractor Development Model of Working for Water

The Working for Water programme of the South African Department of Environmental Affairs has as its major objective the eradication of invasive alien plant species. However, it also has a social development component, which aims at the promotion of small business and entrepreneurship development. This paper explores the socio-economic rationale of one component, the Contractor Development Model. It does so via an examination of the programme’s assumptions, and the development of its impact theory. The study revealed a shortcoming in monitoring data for the programme, and a relative lack of assessment of the effectiveness of its activities. It is suggested that the selection criteria for contractors be re-examined, and that consideration be given to two additional elements that may strengthen the effectiveness of the training: mentoring and networking

Polyamine uptake in the malaria parasite, Plasmodium falciparum, is dependent on the parasite's membrane potential

Polyamines are present at high levels in proliferating cells, including cancerous cells and protozoan parasites and the inhibition of their synthesis has been exploited in antiproliferative strategies. Inhibition of the malaria parasite’s polyamine biosynthetic pathway causes cytostatic arrest in the trophozoite stage but does not cure in vivo infections in the murine model of malaria. This is possibly due to exogenous polyamine salvage from the host, which replenishes the intracellular polyamine pool. This implies that disruption of polyamine metabolism as an antimalarial chemotherapy strategy may require targeting both polyamine biosynthesis and transport simultaneously

The clinical and biochemical effects of riboflavin and nicotinamide supplementation upon Bantu school children using maize meal as carrier medium

A comprehensive clinical, biochemical and technological investigation was undertaken to establish the feasibility of ,enriching maize meal with riboflavin and nicotinamide. It was clear from the results that the addition of these vitamins to, maize satisfied all the prerequisites of a -scientifically sound enrichment scheme, as laid down by the NNRI. It was found that the addition of 1 mg of riboflavin and 10 mg of nicotinamide per 400 g maize ,meal was adequate to effectively reduce the incidence of .subclinical deficiency of these two vitamins among Bantu schoolchildren. Since the enrichment was found to be -effective, as well as technologically and economically jeasible, it is strongly recommended that a compulsory national maize enrichment scheme be introduced with the .least possible delay

The southern African poultry value chain : corporate strategies, investments and agro-industrial policies

Abstract: Following various regional investments in the last decade, production and participation in the poultry value chain in southern Africa has increased. One of the factors that determines entry into, and success in, a global value chain is the governance structure. This paper adopts a modular approach to analyse the governance structures in the poultry value chains in Botswana, South Africa, Zambia and Zimbabwe. A key finding is that various stakeholders have an influence on the regional poultry value chain in southern Africa, with the sources of influence depending on the formality of structures within the value chain

Perbanyakan Mikro Colocasia Esculenta (L.) Schott Var. Antiquorum melalui Penggunaan IAA

Media perbanyakan in vitrosangat diperlukan untuk meningkatkan kemampuan multipikasi tunas maupun kualitas bibit. Media Murashige Shoog (MS)dapatditambahkanzat pengatur tumbuh sebagai pemacu pertumbuhan dalam kultur in vitro.Penelitian ini bertujuan untuk mendapatkan konsentrasi IAA terbaik bagi pertumbuhan talas jepang dalam kulturin vitro. Perlakuan terdiri dari 4 taraf konsentrasi IAA yaitu I0 (0 mg/L), I1 (0,5 mg/L), I2 (1 mg/L), I3 (1,5 mg/L) yang diulang sebanyak 5 kali dalam rancangan acak kelompok. Hasil penelitian ini menunjukan bahwa pemberian IAA berpengaruh nyata terhadap saat muncul tunas, jumlah tunas, tinggi tunas, jumlah daun dan jumlah akar satoimo. Konsentrasi IAA 0,5 mg/L merupakan konsentrasi terbaik untuk pertumbuhan akar dan saat muncul tunas talas satoimo, sedangkan konsentrasi IAA 1 mg/L merupakan konsentrasi terbaik untuk jumlah tunas, tinggi tunas dan jumlah daun satoimo. Kata kunci: kultur in vitro, talas jepang, IAA, perbanyaka

Thrombotic disorders (part 1)

Thromboembolic conditions are the leading cause of mortality, estimated to account for 1 in 4 deaths worldwide in 2010. Over time, the incidence and mortality rates of these conditions have improved in developed countries, but are increasing in developing countries. The haemostatic system comprises 6 main components, i.e. (i) platelets; (ii) vascular endothelium; (iii) coagulation proteins; (iv) natural anticoagulants; (v) the fibrinolytic system; and (vi) natural antifibrinolytic factors. A delicate balance exists between procoagulant and anticoagulant factors within the vascular system. Numerous acquired or inherited conditions may tip the balance either way, i.e. towards a prothrombotic or prohaemorrhagic state. In this issue of CME, the first of a 2-part series on thrombophilic disorders, the subject of discussion is on inherited varieties that the general practitioner is likely to encounter. This review is primarily based on venous thrombosis

The professionalization of pastoral caregiving: a critical assessment of pastoral identity within the helping professions

CITATION: Dames, G. A. & Louw, Daniël J. 2020. The professionalization of pastoral caregiving: a critical assessment of pastoral identity within the helping professions. Stellenbosch Theological Journal, 6(2):103-128, doi:10.17570/stj.2020.v6n2.a5.The original publication is available at: http://www.scielo.org.zaENGLISH ABSTRACT: Pastoral caregiving within a clinical setting and the parameters of interdisciplinarity and a team approach to healing and helping, cannot escape the public demand for a professional approach to caregiving i.e. safeguarding the well-being of people and patients. In this regard, differentiation in terms of theory, paradigmatic conceptualization, and directives for a base anthropology, are paramount. To detect the identity of the pastoral caregiver within the parameters of the pastoral ministry and the Christian tradition of cura animarum, the research focuses on the theological paradigm for comfort and compassion. It is argued that the professional stance of caregivers is shaped by biblical hermeneutics. The theological characteristics of pastoral interventions and engagements are determined by the appropriate God-image of compassionate being-with as pastoral exemplifications of a theologia crucis, directed by a theologia resurrectionis.Publisher's versio

Preface

From text: It cannot be denied that academic psychology, and more specifically the teaching of Psychology, is one of the most neglected areas in South African Psychology. This is regardless of the fact that Psychology is one of the most popular subjects on both undergraduate and postgraduate level at South African universities. Teaching is also the vehicle that takes Psychology students on the road to one of the most respected professions in our country
