In this article three near futures contracts are examined, namely the All Share Near Future, the All Industrial Near Future and the All Gold Near Future, to determine whether daily futures returns exhibit well-documented seasonal patterns. The detection of seasonal patterns in the daily returns for the three underlying indices, namely the All Share Index, the All Industrial Index and the All Gold Index, is also included. Results are compared to the findings of Hattingh Smit. It is shown that seasonal similarities exist between the futures market and the spot market. Seasonal phenomena in the underlying indices further tend to remain stable over the different sample periods considered.

BACKGROUND The impact of climate temperature on the counts (number of positive COVID-19 cases reported), recovery, and death rates of COVID-19 cases in South Africa's nine provinces was investigated. The data for confirmed cases of COVID-19 were collected for March 25 and June 30, 2020 (14 weeks) from South Africa's Government COVID-19 online resource, while the daily provincial climate temperatures were collected from the website of the South African Weather Service. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that no particular temperature range is closely associated with a faster or slower death rate of COVID-19 patients. As evidence from our study, a warm climate temperature can only increase the recovery rate of COVID-19 patients, ultimately impacting the death and active case rates and freeing up resources quicker to enable health facilities to deal with those patients' climbing rates who need treatment. OBJECTIVE This study aims to investigate the impact of climate temperature variation on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperature values. METHODS The data for confirmed cases of COVID-19 were collected for March 25 and June 30 (14 weeks) for South African provinces, including daily counts, death, and recovery rates. The dates were grouped into two, wherein weeks 1-5 represent the periods of total lockdown to contain the spread of COVID-19 in South Africa. Weeks 6-14 are periods where the lockdown was eased to various levels 4 and 3. The daily information of COVID-19 count, death, and recovery was obtained from South Africa's Government COVID-19 online resource (https://sacoronavirus.co.za). Daily provincial climate temperatures were collected from the website of the South African Weather Service (https://www.weathersa.co.za). The provinces of South Africa are Eastern Cape, Western Cape, Northern Cape, Limpopo, Northwest, Mpumalanga, Free State, KwaZulu-Natal, Western Cape, and Gauteng. Weekly consideration was given to the daily climate temperature (average minimum and maximum). The recorded values were considered, respectively, to be in the ratio of death-to-count (D/C) and recovery-to-count (R/C). Descriptive statistics were performed for all the data collected for this study. The analyses were performed using the Person’s bivariate correlation to analyze the association between climate temperature, death-to-count, and recovery-to-count ratios of COVID-19. RESULTS The results showed that higher climate temperatures aren't essential to avoid the COVID-19 from being spread. The present results conform to the reports that suggested that COVID-19 is unlike the seasonal flu, which does dissipate as the climate temperature rises [17]. Accordingly, the ratio of counts and death-to-count cannot be concluded to be influenced by variations in the climate temperatures within the study areas. CONCLUSIONS The study investigates the impact of climate temperature on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperatures as South Africa. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Warm climate temperatures seem not to restrict the spread of the COVID-19 as the count rate was substantial at every climate temperatures. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that there is no particular temperature range of the climatic conditions closely associated with a faster or slower death rate of COVID-19 patients. However, other shortcomings in this study's process should not be ignored. Some other factors may have contributed to recovery rates, such as the South African government's timely intervention to announce a national lockout at the early stage of the outbreak, the availability of intensive medical care, and social distancing effects. Nevertheless, this study shows that a warm climate temperature can only help COVID-19 patients recover more quickly, thereby having huge impacts on the death and active case rates.

This study investigates the trading activity of Chinese stock index futures, recently introduced at the open and close of the underlying trading. We document the impact of the underlying spot on the futures market liquidity as well as volatility as discussed in earlier works on market closure theory. Our empirical results support previous literature on the impact of the underlying, particularly during the open session, as a contagion effect, which is clearly at play. We find significant U-shaped patterns in liquidity factors and intraday volatility during open and close trades in the morning.

The purpose of this paper is to examine two South Africa legislations dealing with over indebtedness of a consumer. It is clear that in terms of the South African law, section 129 (1) and 130 (3) of the National Credit Act provide that a creditor provider who wishes to enforce a debt under a credit agreement must first issue a section 129 (1) (a) notice to the consumer (the purpose of the notice is to notify the consumer of his/her arrears). On the other hand, the South African National Credit Act encourages the consumers to fulfil the financial obligations for which they are responsible. The second legislation to be examined which serve or appear to serve same purpose as the National Credit Act is the Insolvency Act. It therefore, postulated that the compulsory sequestration of a consumer in terms of the Insolvency Act would stand as an alternative remedy for a credit provider before she/he can have recourse mechanisms, such as debt review that are focused on satisfaction of the consumer’s financial obligation , in terms of the provisions of the National Credit Act. The paper determines to what extend these measures comply with the constitutional consumer protection demands. The legislature had been pertinently cognizant of the Insolvency Act when it lately enacted the National Credit Act. This is much apparent from the express amendment of section 84 of the Insolvency Act to the extent set out in schedule 2 of the National Credit Act

Purpose: The purpose of this paper is to analyse the nature of the South African dual manufacturing and services economy and the impact thereof on organisations from a management perspective. Problem investigated: Services account for over 65% of South Africa's gross domestic product (GDP) and reflects an escalating trend. The manufacturing sector of the economy is just over 26% of GDP. This by implication implies that the South African economy is dualistic in nature. The economy functions as an integrated component of the global economy, one that is highly competitive and turbulent in nature. The traditional management approach tends to be one based on a mechanistic, analytical and deterministic manufacturing perspective that is no longer effective in dealing with the services economy. Methodology: A literature study is undertaken and a narrative enquiry conducted by means of discussions with 24 South African executives to determine the impact of the dual economy on South African organisations and the influence thereof from a management perspective. The approach adopted was intentionally analytical-descriptive in nature. The narrative enquiry constituted open ended but structured discussions with executives in order to learn from their personal experiences in managing an organisation in what is termed to be the dual South African services and manufacturing economy. Findings: An important conclusion drawn from the study is that traditional paradigms of management that evolved within a mechanistic manufacturing economy is no longer effective for dealing with the unpredictable and disruptive changes of a highly competitive global services economy. A complexity theory based management approach it would appear may be more relevant in dealing with the emergent realities associated with a turbulent services economy. Value of the research: Seen within the context of the changing nature of the global and South African economy, the insights gained from the study could assist executives and managers in exploring alternative paradigms of management that would be more appropriate for dealing with the paradoxical nature of a dualistic economy. Conclusion: Appropriate management paradigms differ in terms of contextual realities confronting managers, namely dealing with ordered and un-ordered contextual conditions. The Cynefin Framework (Kurtz & Snowden, 2003) serves as a means of sense making in finding the most appropriate management response for dealing with the contextual realities associated with a dualistic economy.
