An analysis of Edcon v Steenkamp with reference to its effect on the “De Beers” principle
No full textIn this article, the author deals predominantly with the judgment handed down in
Edcon v Steenkamp.1 Here the applicant described its application as “a constitutional
challenge”2 to section 189A of the Labour Relations Act,3 a primary object
of the Act being to give effect to and regulate the fundamental rights conferred
by section 23 of the Constitution of the Republic of South Africa, 1996.4 It is
also considered in what manner the Edcon judgment differs from the judgment in

UK Renal Registry 12th Annual Report (December 2009): chapter 7: survival and causes of death of UK adult patients on renal replacement therapy in 2008: national and centre-specific analyses
No full textIntroduction: These analyses examine survival from the start of renal replacement therapy (RRT), based on the total incident UK RRT population reported to the UK Renal Registry, including the 19% who started on PD and the 5% who received a pre-emptive transplant. Survival of prevalent patients and changes in survival between 1997 and 2007 are also reported.Methods: Survival was calculated for both incident and prevalent patients on RRT and compared between the UK countries after adjustment for age. Survival of incident patients (starting RRT during 2007) was calculated both from the start of RRT and amongst the cohort who survived at least 90 days after RRT, and both with and without censoring at transplantation. Both the Kaplan-Meier and Cox adjusted models were used to calculate survival. Causes of death were analysed for both groups. Relative risk of death was calculated compared with the general UK population.Results: The 2007 unadjusted 1 year after 90 day survival for patients starting RRT was 86.2%. In incident 18-64 year olds the unadjusted 1 year survival had risen from 85.9% in 1997 to 92.4% in 2007 and for those aged >65 it had risen from 63.8% to 74.9%. The age-adjusted survival (adjusted to age 60) of prevalent dialysis patients rose from 85% in 2000 to 89% in 2007. Diabetic prevalent patient survival rose from 76.5% in 2000 to 83.0% in 2007. The age-standardised mortality ratio for prevalent RRT patients compared with the general population was 28.6 at age 30 years (and was lower than in the 1998-2001 cohort in all age groups up to 45-49) and 4.6 at age 80 years. In the prevalent RRT dialysis population, cardiovascular disease accounted for 29% of deaths, infection 17% and treatment withdrawal 14%. Of deaths, 26% were recorded as uncertain. Treatment withdrawal was a more frequent cause of death in patients aged >65 at start than in younger patients. The median life years remaining for a 25-29 year old on RRT was 20 years and 5 years for a 70 year old.Conclusions: Incident 2007 and prevalent 2008 patient survival on RRT in all the UK countries for all age ranges and also for patients with diabetes continued to improve. The relative risk of death on RRT compared with the general population has fallen since 2001. Death rates on dialysis in the UK remained lower than when compared with a similar aged population on dialysis in the USA
AASB138 catalyst to changes in managerial decisions and reduced R&D spending? /
No full textThe Australian accounting standard for research and development (R&D) effective from 1 January 2005 (AASB138) contains more stringent requirements regarding the capitalisation of R&D spending than its predecessor (AASB 1011). The majority of R&D spending now has to be expensed immediately. This affects earnings significantly. Investment in R&D is critical in maintaining competitive advantage and increases a firm’s probability of survival. However, prior research found companies sacrifice long-term value to smooth earnings and that managers cut R&D spending in response to target-driven earnings pressures. Sacrificing long-term value and returns in pursuit of short-term returns is referred to as short-termism. It is possible that AASB 138 could have discouraged managers to invest in R&D activities and that they may have chosen to reduce R&D spending as a means to manage earnings and meet expected profits. This study investigated these issues using financial data of 31 Australian listed firms for financial years from 2001 to 2010. A regression model was used to ascertain if short-termism affected R&D spending. Research intensity ratios were also calculated to determine trends in R&D spending. The study found a marked increase in the significance of short-termism in explaining changes in R&D of companies that capitalised R&D in accordance with AASB 1011. Furthermore, the the median research intensity ratio of companies that capitalised R&D under AASB 1011 declined almost three time that of companies that expensed R&D after the introduction of AASB 138. The study’s findings suggest that AASB138 could have been a catalyst to changes in managerial decisions in pursuit of short-termism that resulted in reduced R&D spending as a means to manage earnings

Does workload and institutional pressure on accounting educators affect academia at Australian universities?
No full textSteenkamp, N ORCiD: 0000-0001-7489-5984This paper examines accounting academics' perceptions as to whether institutional pressure has increased in the previous 5-10 years subsequent to changes in the higher education environment, encouraging universities to adopt private sector managerialism. Results from 87 respondents indicated that workload pressures have increased and they experienced pressure to perform acts related to a student-as-customer model, which have negatively affected their well-being and work quality. The majority are not actively seeking to leave academia, but believe it is not a good time for others to aspire to such a career. This paper contributes to the debate about the sustainability of accounting academia at Australian universities. © 2018 AFAANZ
Seal bites at sub-Antarctic Marion Island: Incidence, outcomes and treatment recommendations
No full textSeal biologists at Marion Island (Southern Ocean) are in frequent contact with seals. During research activities, biologists may be bitten by seals, yet no standardised protocol for treating such bites is in place. Information on 22 seal bite cases at Marion Island was collected. Treatment of these bites varied, reflecting a need for standardised protocols for the treatment of bites. Recommendations for the in-field treatment of bites are presented. Five of the 22 cases had some symptoms which resembled ‘seal finger’ – a zoonotic infection, usually of the hands, that is contracted after a person comes into contact with tissues of seals or is bitten by one. However, in four of these cases, symptoms subsided within 4 days without antibiotic treatment; in the fifth case antibiotics were administered and symptoms subsided in 4 days. There is little evidence of the occurrence of seal finger at Marion Island, but this deserves further investigation.</p
South Africa's Defence Diplomacy in Africa
No full textCITATION: Liebenberg, I. & Steenkamp-Fonseca, R. 2020. South Africa's Defence Diplomacy in Africa, in Liebenberg, I., Kruijt, D. & Paranjpe, S. (eds) 2020. Defence diplomacy & national security strategy : views from the global south. Stellenbosch: SUN PReSS, doi:10.18820/9781928480556/06.The original publication is available at https://africansunmedia.store.it.si/zaSouth Africa’s defence posture in Africa changed radically between 1950 and 2018. From a garrison-minded state mired
in diplomatic isolation, the country ‘returned to Africa’ following its negotiated transition to democracy. As South Africa’s
relations on the continent evolve, so too does the country’s use of various instruments of foreign policy. This chapter primarily
considers the military instrument in foreign policy, and in particular the country’s policy and practice of defence diplomacy.
Shaped in part by the presidential styles of Nelson Mandela, Thabo Mbeki, and Jacob Zuma, the interplay between foreign
policy and defence has required South Africa to ensure it is not perceived as a hegemon by its neighbours in Africa, but as
a declared partner – albeit often as the dominant partner. Even so, expectations continue that South Africa should extend
its role in the African Union (AU), and through the African Peace and Security Architecture (APSA) it helped to establish. As
the chapter notes, significant gains have been made in advancing South African interests through defence diplomacy, but
real limitations exist and these should be considered rationally before unrealistic demands or inflated expectations are
uncritically accepted.Publisher's versio
