    Opis:
    There is a growing literature on the conditions of Zimbabwean women working as migrant workers in South Africa, specifically in cities like Johannesburg. Based on in-depth interviews and documentary analysis, this empirical research paper contributes to scholarship examining the conditions of migrant women workers from Zimbabwe employed as precarious workers in Johannesburg by zooming in on specific causes of migration to Johannesburg, the journey undertaken by the migrant women to Johannesburg, challenges of documentation, use of networks to survive in Johannesburg, employment of the women in precarious work, and challenges in the workplace. Rape and sexual violence are threats that face the women interviewed during migration to Johannesburg and even when in Johannesburg. The police who are supposed to uphold and protect the law are often found to be perpetrators involved in various forms of violence against women. In the workplace, the women earn starvation wages and work under poor working conditions. Human rights organizations and trade unions are unable to reach the many migrant women because of the sheer volume of violations against workers’ rights and human rights.

    Opis:
    This paper investigates the properties of South African stock returns and the underlying variance. The investigation into the properties of stock returns and the behaviour of the variance underlying returns is undertaken using model-free approaches and through the application of ARCH/GARCH models. The results indicate that, as with other stock markets, returns on the South African stock market depart from normality and that variance displays evidence of heteroscedasticity, long memory, persistence, and asymmetry. Applying the EGARCH(p,q,m) and IGARCH(p,q) specifications confirms these findings and the application of these models suggests differing characteristics for variance structures underlying the South African stock market. In light of the findings relating to the properties of stock returns and the characteristics of variance and its structure, implications are outlined, and recommendations on how time-series specifications may be estimated are made.

    Opis:
    The present study aims at evaluating the quality of shallow groundwater (SGW) and its suitability for irrigation purpose in the most urbanised part of Johannesburg city, South Africa. The SGW samples were collected in three consecutive years and analysed for 20 selected physicochemical parameters, and heavy metals. The results were compared with the South African water quality, and Food and Agricultural Organization irrigation water quality guidelines, and standard indices derived from laboratory outputs. The results of the study show that all physiochemical parameters and heavy metals were within the limits set by both guidelines for irrigation purposes, except for potassium (3.58 mg∙dm-3) and manganese levels (3.152 mg∙dm-3). The calculated irrigation parameter values of sodium adsorption ratio (SAR), sodium percentage (Na%), residual sodium carbonate (RSC), magnesium hazard (MH), Kelly’s ratio (KR) and permeability index (PI) were within the permissible range of irrigation water quality standards. The findings of this study provide helpful information for decision-makers such as utilisation of the studied groundwater for irrigation uses.

    Opis:
    The article takes up the issues connected to the ecological crisis, causes of which refer to uncontrolled scientifically-technical development, predatory administration of the natural sources of Earth and disrespect of the nature, following from the anthropocentric axiology, the analysis of the Stockholm’s Declaration, the Declaration from Rio and the declaration from Johannesburg, as documents forming the idea of the sustainable development, active that care and respect of nature and preventing degratation of natural environment make a basis of the agricultural and social development and the only rational way to get out of the ecological crisis without radical reduction the quality of human’s life. In discussed declarations they point out the individual, collective and institutional responsibility. It’s set up that the basis of the responsibility figured out like that - for the other human, for present and future generations, for the nature, for the global human’s society, for other communities of alive creatures, for the planet - should be ecophilosophy and systematic sozology. Basing on this two sciences we can make a socio-economical and ecological order indicated in the sustainable development conception.
