GEOCHEMICAL SOIL MAPPING, PHYTOEXTRACTION OF CRITICAL ELEMENTS AND ENERGY PLANT PRODUCTION IN THE POST MINING AREA OF FREIBERG

The soil, heterogeneous in nature, is a very important part of the environment. It plays a major role in the existence, health and functioning of the organisms found in it, the other compartments of the biosphere and the life forms in them. Therefore, a negative deviation from a healthy soil will have a great impact on the biosphere and the environment at large. Some of these unhealthy deviations are caused by human activities and the aftermath of such activities such as mining and resource prospecting within the earth crust. Since these deviations are now very common and because economic gains from mining and prospecting of resources must continue, several research works are focused on highlighting the possible ways of carrying out sustainable mining and restoring the soil back to health conditions

Can the restrictive harvest period policy conserve mopane worms in Southern Africa? A bio-economic modelling approach

Imbrasia Belina also known as the mopane worm, like other edible insects and caterpillars, is a vital source of protein to Southern African countries. The worms live and graze on mopane trees, which occupy agricultural land. With increasing commercialization of the worm, the management of the worm, which was hitherto organized as a common property resource, has degraded to a near open access. In this paper, a simple bio-economic modeling approach has been taken to show that, for some optimal land allocation, the restrictive period harvest season policy that is advocated by community leaders may not lead to sustainable harvesting of the worm.

Free Your Mind: Contemporary Racial Attitudes and Post Racial Theory

The inauguration of the United States first Black President has prompted mass discussions of race relations in America. It is often articulated that America is now in a post-racial society. However, the question still remains: does the election of a Black president demonstrate that America is now a color-blind society? To answer this question, we rely on data collected by PEW (2007). Our results suggest that white and African Americans differ significantly in the extent to which they express post-racial attitudes. Specifically, we find that whites more commonly express post-racial attitudes, claiming that racism and discrimination are rare, in opposition to African American views. On the other hand, blacks are more likely to believe that discrimination still occurs. We further find that whites\u27 post-racial beliefs are significant determinants of their attitudes towards race-related policies, such as affirmative action.

Speech pathologists and audiologists in the training of community rehabilitation workers : ethical issues.

A research report presented to the Department of Speech Pathology and Audiology, Faculty of Arts, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirement for the degree Master of Arts in Speech- Language Pathology by CourseworkHealth care professionals are expected to apply ethical principles such as nonmaleficence, beneficence, autonomy and justice in their teaching of students and treatment of clients. Speech Pathologists and Audiologists (SPAs) in South Africa are responsible not only for educating members of their profession, but are often also involved in the training of Community Rehabilitation Workers (CRWs). Hence the aim of the present study was to explore the experiences, opinions and attitudes of a group of SPAs and CRW co-ordinators with particular reference to ethical issues related to CRW training. In order to investigate this aim. an interview schedule followed by a questionnaire were administered to SPA and CRW co-ordinators who had been involved in CRW training at The Wits/Tinstwalo CRW Training Programme in Gazankulu and at The Institute Of Urban Primary Health Care in Alexandra Township. Data elicited from the interview were analysed using content analysis and responses categorized according to respondents' background in ethics and knowledge regarding ethical principles. Results are discussed in terms of their implications for SPA and CRW co-ordinators.Andrew Chakane 201

A Corpus of Roman Pottery from Lincoln (Volume 6)

This is the first major analysis of the Roman pottery from excavations in Lincoln (comprising more than 150,000 sherds). The pottery is presented in seven major ware groups. Fine wares include a modest range of imports and are dominated by Nene Valley products. Oxidised wares are mostly local products with a few imports as are the shell- and calcite-tempered wares and reduced wares. The final three are the standard specialised wares: mortaria, mostly of German and Mancetter-Hartshill manufacture; amphorae (80% Spanish Dressel 20) and samian, mostly from Les Martres/Lezoux and 75% undecorated! The discussion explores the chronological range of the entire ceramic assemblage across the three discrete parts of the Roman fortress and later colonia
