Black economic empowerment in the South African mining industry : a case study of Exxaro Limited

The original publication is available at http://reference.sabinet.co.za/sa_epublication/busmanThis paper explores some of the key challenges and opportunities in the implementation of the broad-based black economic empowerment (BBBEE) deal of Kumba Resources, which subsequently led to the formation of Exxaro Limited, a large black-owned mining conglomerate in South Africa. Qualitative data were collected through in-depth interviews with a sample of 11 leaders involved directly in the deal. The data were content-analysed and the findings suggested that BEE transactions faced numerous challenges, including finding sustainable funding, securing suitable investors, merging various cultures, dealing with fronting and leadership, and planning management and leadership succession. The study concluded that the deal led successfully to both the equitable transfer of ownership and management and to the control of financial and economic resources to a wider base of the black population. However, several malpractices were identified which may have impeded the process of achieving the intended outcomes. The article provides recommendations, indicates limitations and proposes a way forward.Publishers' versio

Efficiency and Profitability Analysis of Agricultural Cooperatives in Mpumalanga, South Africa

Agricultural cooperatives are expected to generate sustainable profit as they are established as a vehicle of economic development. Efficiency and profitability analysis measures the performance of a firm, and assists management in decision-making through benchmarking with other firms (Marwa & Aziakpono, 2014). To understand the performance of agricultural cooperatives, our study analysed efficiency and profitability using an efficiency-profitability matrix to provide for multi-dimensional analysis. The study used secondary data from annual financial statements for the financial years 2015/16 collected from 19 agricultural cooperatives. Technical efficiency was estimated using Data Envelopment Analysis (DEA) and profitability was estimated using Returns on Assets (ROA). The median scores were 68% for technical efficiency and 10% for profitability. Using the 68% efficiency and 10% profitability benchmark, the matrix separated best performers from low performers. The matrix indicated that 26% of the cooperatives had high-efficiency levels with high profitability (stars), however there was an even distribution between the stars and sleepers: 5 out of 19 cooperatives were sleepers and 5 out of 19 were stars. The majority of the decision-making units (DMUs) at 42% (8 out of 19) are in quadrant 3, categorised as ‘question mark’. These DMUs had low-efficiency scores and low profitability ratios. Only 1 out of 19 cooperatives had high-efficiency levels and low profitability scores. The results demonstrate that technically efficient firms do not always translate to profitable firms: in this regard, management needs to investigate how best to allocate resources in order to remain relevant within the business context and competition. Policy makers need to investigate other drivers of efficiency and profitability when measuring the performance of a firm to influence future policy directives

Coordination chemistry and biology of chelators for the treatment of iron overload disorders

Treatment of the medical condition generally referred to as iron overload through the delivery of chelators has recently received a major boost. In 2005 Novartis gained FDA approval for the drug deferasirox, which may be taken orally. Until this time most patients with Fe overload have had to endure long periods of subcutaneous infusions of the orally ineffective drug desferrioxamine (desferal) which has led to major problems with patient compliance. An effective Fe chelator must possess a number of properties for it to be able to complex Fe in vivo and be excreted intact. This Perspective will provide an overview of the current state of chelators for Fe overload; both those currently approved and those undergoing preclinical development

Polycystic ovary syndrome

The document attached has been archived with permission from the editor of the Medical Journal of Australia. An external link to the publisher’s copy is included.Polycystic ovary syndrome (PCOS) affects 5-20% of women of reproductive age worldwide. The condition is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology (PCOM) - with excessive androgen production by the ovaries being a key feature of PCOS. Metabolic dysfunction characterized by insulin resistance and compensatory hyperinsulinaemia is evident in the vast majority of affected individuals. PCOS increases the risk for type 2 diabetes mellitus, gestational diabetes and other pregnancy-related complications, venous thromboembolism, cerebrovascular and cardiovascular events and endometrial cancer. PCOS is a diagnosis of exclusion, based primarily on the presence of hyperandrogenism, ovulatory dysfunction and PCOM. Treatment should be tailored to the complaints and needs of the patient and involves targeting metabolic abnormalities through lifestyle changes, medication and potentially surgery for the prevention and management of excess weight, androgen suppression and/or blockade, endometrial protection, reproductive therapy and the detection and treatment of psychological features. This Primer summarizes the current state of knowledge regarding the epidemiology, mechanisms and pathophysiology, diagnosis, screening and prevention, management and future investigational directions of the disorder.Robert J Norman, Ruijin Wu and Marcin T Stankiewic

Expatriate women managers: at the crossroads of success, challenges and career goals

The current study explores the unique experiences of expatriate women managers, in procuring international assignments, adjusting to the cross‐cultural conditions on global tours and confronting the challenges affecting their career goals. In‐depth interviews were conducted with 25 expatriate women managers from multinational organizations operating in South Africa to collect qualitative data that was content analyzed. Result findings suggest that women are not only successful as expatriates in foreign countries, but with adequate performance, they also achieve career growth and promotion. Conclusions indicate that, professional foreigners, regardless of gender, may want to explore cultural challenges in countries with new democracies. It also provides suggestions for the way forward. </jats:p

Experiences with Queen Bees: A South African study exploring the reluctance of women executives to promote other women in the workplace

This study explores the experiences of women executives and senior managers in South Africa in respect of the Queen Bee syndrome. Queen Bee behaviour is a term used to describe women executives that, after reaching senior positions, alienate other women and hence prevent more junior women from advancing through the ranks. Such behaviour has in the past specifically been observed in corporate environments with a tradition of male domination. This study specifically focussed on the banking sector as an example of a previously male-dominate environment.Twenty-five women executives and senior managers from South Africa’s five national retail banks were interviewed to obtain data on their unique personal experiences and perceptions of Queen Bee behaviour. The qualitative data were then content-analysed.This study is one of the first studies that reports on Queen Bee behaviour in South Africa, and confirms the existence of Queen Bee behaviour in South Africa, despite the efforts in the corporate world to advance the gender cause. While this paper does not provide evidence that women’s advancement and growth in corporate organisations are solely reliant on the support and assistance of other women it, however, indicates the constraints of a hierarchical and male lead work culture in most organisations that could be a block to the promotion of professional women.Future studies are required to investigate the other sectors and to develop tools to detect and discourage Queen Bee behaviour.</jats:p
