The impacts of Section 54 stoppages on staff morale

Abstract: The main reasons for the issuing of Section 54 notices under the Mine Health and Safety Act, 29 of 1996 (MHSA) is the failure of mining operations to comply with the Act. When health and safety standards and procedures have not been properly implemented and do not comply with the MHSA, a Section 54 notice is likely to be issued by the Inspector of Mines from the Department of Mineral Resource (DMR). Section 54 of the MHSA states that ’If an inspector has reason to believe that any occurrence, practice or condition at a mine endangers or may endanger the health or safety of any person at the mine, the inspector may give any instruction necessary to protect the health and safety of persons at the mine’. Section 30 of the Occupational Health and Safety Act, 85 of 1993 (OHSA) also grants an inspector powers to deal with dangerous conditions. A number of statements and reports have been published about the impacts of Section 54 on the mining business, but very little (if any) information is available on the impact on mineworkers’ morale. In 2011, Section 54 stoppages cost the South African economy $500 million by losing 300 000 precious metal ounces of production (Mining Weekly, 2012). Warren Beech of Hogan Lovell law firm believes that Section 54 stoppages affect the morale of the team, the health and production momentum of the team, and the remuneration of employees, which includes the safety bonus (Naidoo, 2014). This paper explores the impacts of the issuing of Section 54 notices on mineworkers’ morale, using a platinum mine in the North West Province as a case study

Corruption and Its Implications for Development and Good Governance: A Perspective from Post-Colonial Africa

Abstract: One of the many impediments to a specific region, country and/or continents political, social and economic growth prospects is corruption, the aim of this paper is to unearth the drivers and consequences of corruption in post-colonial Africa. Corruption is a global phenomenon; however when observing global corruption statistics and/or trends, it seems to be more prominent in underdeveloped continents such as Africa. Corruption in Africa is purely driven by low levels of economic growth, bad governance structures weak constitutions political instability, high levels of poverty coupled with high and ever-increasing levels of unemployment. We argue that post the colonial era, there has been a rise of corruption activities within the continent where individuals including some African heads of states have looted the continent of its resources meant for the general populace. In this sense, corruption takes resources meant for the poor, limits foreign direct investments (FDI) and has severe effects on a continent that is already the least developed in the world

Trends in the utilization of medicines sold in the private sector post-registration in South Africa and the implications for similar countries

Background: Regulatory authorities register medicines for patients to access them within a reasonable period of time. There is a paucity of available data regarding the extent to which registered medicines reach the public after market authorisation is granted by the South African Health Products Regulatory Authority (SAHPRA). This is important since time spent by SAHPRA assessing medicines that are subsequently not launched onto the South African market means time wasted, which could be spent on assessing new medicines that address an unmet need in the country. Consequently, we initially analysed the time taken for registered medicines to reach patients and the relationship between medicines registered at SAHPRA and those subsequently dispensed in private pharmacies. The extent of registration of multiple sourced versus new patented medicines was also explored. Methods: A retrospective, descriptive and quantitative investigation was conducted for medicines registered between 2014 and 2019. Registered and dispensed medicines were compared to establish accessibility post registration. Data sources included SAHPRA and IQVIA datasets. Microsoft Excel and SAS were used for data storage, analysis, and computation of descriptive statistical analysis. Results: Of (N=2175) registered medicines, only 358 (16.5%; 95% CI 15.0% - 18.1%) were dispensed to patients, and out of 1735 medicines registered between 2015 and2019, only 57 (3.3%; 95% CI 2.5% - 4.2%) were dispensed during the study period. Medicines acting on the central nervous system were registered and dispensed the most at 21.0% and 18.0%, respectively, whereas antineoplastic and immunomodulation agents were registered and dispensed only 11% and 5%, respectively. A concern was that only 13.0% of registered medicines were originators, with most either as generics, including branded generics, or pseudo-generics. Conclusion: Regulatory measures should be implemented to ensure increased medicine access post-registration for new originators, especially for priority disease areas that benefit patients. Mental health diseases and improved access to oncology medicines require special attention and further investigation in South Africa

Tungsten oxide thin film for room temperature nitrogen dioxide gas sensing

Tungsten oxide (WO3) thin films for gas sensing have been successfully deposited using reactive direct current (DC) magnetron sputtering at different deposition temperatures (300 °C, 400 °C and 500 °C). The structural, morphological properties, thickness and composition have been investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) and Rutherford backscattering spectrometry (RBS) techniques. To investigate the effect of deposition temperature on the gas sensing properties of deposited thin films on alumina substrates, was conducted using the Kenosistec gas sensing unit. WO3 thin film deposited at 500 °C exhibited a higher response when sensing Nitrogen dioxide (NO2) at room temperature as compared to the thin films prepared at 300 °C and 400 °C, respectively. However, as deposited WO3 thin films exhibited low sensitivity when sensing reducing gases such as hydrogen (H2) and ammonia (NH3), which was an indication of good selectivity properties of WO3 related sensors

Paravertebral paraganglioma with spinal extension: a case report

Abstract Background Paragangliomas are rare neuroendocrine tumors. While paragangliomas of the spine are rare, those located in non-cauda equina areas with spinal canal extension are even rarer. Case presentation We present a case of a 23-year-old female of African descent with a primary thoracic paraganglioma with intervertebral extension resulting in displacement and compression of the spinal cord and extensive local invasion of the surrounding structures. This paraganglioma was functional with typical symptoms of catecholamine excess. Despite the aggressive nature of the paraganglioma, the patient only had isolated sensory symptoms in the left shoulder. Adequate alpha and beta-blockade were instituted prior to her undergoing surgery with near-total resection and complete preserved neurology. There was no underlying pathogenic genetic mutation found. Conclusions Even though rare, paraganglioma should be considered in the differential diagnosis of spinal tumors. Genetic testing should be performed in patients with paragangliomas. One should exercise extreme caution in treating such rare tumors that may cause neurological deficits and careful surgical planning should be undertaken to avoid possible catastrophic complications
