Will COVID-19 Reverse the Gains Made in Occupational Health and Safety in the Mining Sector in South Africa?

This paper reviews the possible impact of the Corona Virus (COVID-19) pandemic on the Mining and Mineral Industry (MMI) in South Africa. It examines the possible impact of COVID-19on the industry milestones on Occupational Health and Safety (OHS) agreed at the industry tripartite summit in 2014 which had ambitious targets of reaching zero harm in the industry and minimising occupational diseases by 2024. The paper used secondary data from the department of mineral resources. The analysis showed that (1) the industry has already missed some of the industry milestones towards the 2024 targets such as zero fatalities by 2020 and many other targets in health are also lagging behind. (2). PTB remains the dominant occupational diseases in the mining sector in South Africa constituting about 50% of major occupational diseases in the sector. (3) COVID-19 Positive continue to increase in the sector and it is being seen as a new epicentre for COVID-19 in the country despite the mandatory guidelines for OHS in the sectorin terms of the Mine Health and safety Act (MHSA) published by the Department of Mineral Resources and Energy (DMRE) to respond to COVID-19. There is a need for the industry stakeholders to work together to reduce the impact of COVID-19 on the sector and improve occupational health outcomes towards the 2024 targets

Green marketing, green corporate governance commitment, and its impact on firm performance : the case of electronic manufacturers in South Africa.

Thesis (Ph.D. (Marketing))--University of the Witwatersrand, Faculty of Commerce, Law and Management, School of Economic & Business Sciences, 2017The purpose of this research was to study the relationship between firm‟s commitment to green, green marketing capability, green relationship learning, green human resource investments and firm performance for electronics manufacturers in South Africa. Despite the increased focus on on green marketing, there has been little focus on research relating corporate commitment to green and how it relates to green marketing capabilities and firm performance. This study fills this research gap by proposing and testing hypotheses relating firm commitment to green, green marketing capability, green relationship learning, green human capital investment and a firm‟s performance. To answer the research questions, primary data for n=212 respondents covering a range in firm size, gender, race, and age for electronics manufacturers in South Africa was used to test the hypothesis relating corporate commitment to green, green marketing capability, and a firm‟sperformance. The structural equation modeling approach was used to test the model fit and hypothesis testing. The software SPSS 24 was used to analyse the descriptive statistics and AMOS 24 was used to test the research model. The results showed that firm commitment to green was a predictor of firm performance and green marketing capability, green relationship learning, and green human capital investments was found to be mediators in the relationship between firm commitment to green and firm performance. Indeed, the hypotheses stated in this study were found to be true. The main contribution of this study is showing how corporate governance commitment to green can enable firm performance (both marketing and financial) through mediating variables of green marketing capability, green relationship learning and green human capital investment. The study further shows that corporate commitment to green influences green corporate social investment positively. Key words: corporate commitment to green, green marketing capability, green relationship learning, green Human Capital Investment, Green CSI, firm performanceGR201

Teachers\u27 Profile, Knowledge Competence, and Skill Competence in Laboratory Instruction; Its Implications to Physics Teaching

Effective science instruction requires more than just dispensing information and conceptual knowledge; science teachers also need to have in-depth knowledge, understanding, and abilities to give their students appropriate and pertinent scientific tasks. Despite the fact that teachers exhibit proficiency in laboratory instruction, more research is required to determine how this proficiency directly impacts student learning outcomes in lab environments. Hence, a descriptive-correlational research approach was conducted to determine the relationship between the profile of science teachers and their knowledge and skill competence in science laboratory instruction. Results revealed that gender (sex) has a negative correlation with both knowledge and skill competency. This indicates that male and female teachers may have different competency levels. Moreover, higher degrees and teachers’ field of specialization contribute positively to both knowledge and skill competency in science laboratory instruction. However, teaching position and length of teaching have weak indicating that experience alone may not strongly influence knowledge and skill competence in science laboratory

Bioqualité Des Formes De Dissémination Des Protozoaires Flagellés Entériques Dans Les Eaux Souterraines (Sources Et Puits) En Zone Anthropisée (Yaoundé-Cameroun)

With an aim of characterizing the cysts of flagellated enteric protozoa present in groundwater of the town of Yaoundé, a descriptive and analytical study was carried out from February to July 2015 on the samples of 6 springs and 6 wells in 6 quarters of the city. The physico-chemical analysis proceeded at the same time on the field and at the laboratory. The observation of the cysts of the flagellated protozoa was done under the inverted microscope of mark Olympus CK2 to the objective 40X after concentration of the samples according to the method of sedimentation and the method of floating. The physicochemical analysis revealed slightly acid water (6, 04 ± 0, 49 U.C), average mineral-bearing (533, 70 ± 346, 18 µS/cm) and rich in suspended matter (14, 14 ± 11, 35 mg/L). The biological analyses revealed the presence of the cysts of the flagellated Protozoa with average densities of 162±115 cysts/L for Giardia intestinalis, 262 ± 280 cysts /L for Chilomastix mesnili, 89±101 cysts /L for Enteromonas hominis and 72 ± 80 cysts /L for Retortamonas intestinalis. In general, the greatest densities of cysts were recorded during the rainy season. The statistical tests revealed positive correlation between the cystic densities with MES, the color, turbidity and the organic matter (p < 0,05), and also negative correlation with nitrate (p < 0,05).This very high parasitological pollution makes water unfit for consumption. The use of untreated spring waters and wells could constitute a significant heath for the households living in the zone of study
