South African Grade 9 teachers' and learners' knowledge about medicinal plants and their attitudes towards its integration into the science curriculum

A research report submitted to the Faculty of Science in partial fulfilment of the requirements for the degree of Master of Science. Johannesburg, 2013.The integration of indigenous knowledge into the mainstream science curriculum has been advocated for by science educators around the world. The Revised National Curriculum Statements (RNCS) for Grades R-9 (Natural Sciences) clearly advocates for the incorporation of indigenous knowledge into the science curriculum. They stipulate that learners must learn science within the context of their historical, societal and cultural knowledge and values. It is important that learners should understand other systems of knowledge, such as indigenous knowledge systems (IKS). The underlying assumption is that teachers can help learners integrate science and indigenous knowledge but in order to do that, they too must have adequate knowledge and understanding regarding the two thought systems. The challenge is that some teachers are not well informed about the varying indigenous knowledge that typifies the multi-cultural situation in South African classrooms as they have been schooled in western science The study aimed at eliciting learners‟ and teachers‟ knowledge about traditional medicinal plants and their attitudes towards integration of that knowledge into the science curriculum. This was with a view to exploring any differences or similarities between the views of teachers and learners. A case study was carried out at a secondary school in Meadowlands, Soweto. A sample of 36 Grade 9 learners and 10 teachers of Natural sciences was selected using the convenience sampling technique. Structured pictorial questionnaire was used to collect data from both teachers and learners. Field notes were taken during a class debate on the effectiveness of traditional medicines versus western medicines. Unstructured follow up interviews (5 learners- group interview and 3 teachers-individual) were performed on selected participants to probe further their responses to the questionnaire. A ROSE1 type questionnaire was used as a follow up when learners were in grade 10 (2013). Analysis of the findings showed that a majority of learners and teachers that participated in this research have opposing attitudes regarding the need to integrate knowledge about traditional medicinal plants into the science curriculum. The 1ROSE-Relevance Of Science Education, a questionnaire distributed in many countries by Prof Svein Sjøberg, ILS, University of Oslo, Norway. learners in this study had generally more knowledge that the teachers about traditional medicinal plants. The majority of learners are willing to learn about indigenous knowledge (IK). Nine teachers out of ten in this study were generally less enthusiastic about teaching about traditional medicinal plants. In light of the findings it is recommended that teachers need to have in-house training in so far as the methodological aspects of integrating components IK into the science curriculum relate. This may go a long way in limiting conceptual conflicts amongst the learners

Objectives: A commercial chemical, biological, radiological and nuclear (CBRN) protective covert garment has recently been developed with the aim of reducing thermal strain. A covert CBRN protective layer can be worn under other clothing, with equipment added for full chemical protection when needed. However, it is unknown whether the covert garment offers any alleviation to thermal strain during work compared with a traditional overt ensemble. Therefore, the aim of this study was to compare thermal strain and work tolerance times during work in an overt and covert ensemble offering the same level of CBRN protection. Methods: Eleven male participants wore an overt (OVERT) or covert (COVERT) CBRN ensemble and walked (4 km·h-1, 1% grade) for a maximum of 120 min in either a wet bulb globe temperature [WBGT] of 21, 30, or 37°C (Neutral, WarmWet and HotDry, respectively). The trials were ceased if the participants' gastrointestinal temperature reached 39°C, heart rate reached 90% of maximum, walking time reached 120 min or due to self-termination. Results: All participants completed 120 min of walking in Neutral. Work tolerance time was greater in OVERT compared with COVERT in WarmWet (P 0.05). Conclusion: Those dressed in OVERT experienced lower thermal strain and longer work tolerance times compared with COVERT in a warm-wet environment. However, COVERT may be an optimal choice in a hot-dry environment. These findings have practical implications for those making decisions on the choice of CBRN ensemble to be used during work.This project is financially supported by the Australian Government, managed by the National Security Science and Technology Centre within the Defence Science and Technology Organization, and the US Government through the Technical Support Working Group within the Combating Terrorism Technical Support Office.Published versio

Increasing Quality and Profitability in New York Vineyards Using NEWA, Cornell’s Weather and Pest Network

NYS IPM Type: Project ReportThe multipronged approach to grower training on the use of NEWA resources by the NYS IPM Program, in conjunction with Cornell’s regional and area Grape Program Extension Teams, has resulted in savings by New York grape growers from $1 an acre to over$50 per acre. NEWA, the Network for Environment and Weather Applications, is a free, web-based weather and pest model information system (http://newa.cornell.edu/). While it was well know across the grape industry that the research-based information found on NEWA could help growers in developing and implementing their yearly pest management strategy, there was a resistance on the part of the growers to access the web site. Using a combination of traditional and innovative information transfer tools, the project team was able to dramatically increase the number of growers that not only accessed the information, but implemented it as well

Comparison of Three Dispenser Distribution Patterns for Pheromone Mating Disruption of Paralobesia viteana (Lepidoptera: Tortricidae) in Vineyards

Over two growing seasons, Isomate GBM-Plus tube-type dispensers releasing the major pheromone component of grape berry moth, Paralobesia viteana (Clemens) (Lepidoptera: Tortricidae), were evaluated in vineyards (Vitis spp.) in Michigan, New York, and Pennsylvania. Dispensers were deployed in three different density-arrangement treatments: 124 dispensers per ha, 494 dispensers per ha, and a combined treatment with 124 dispensers per ha in the vineyard interior and 988 dispensers per ha at the vineyard border, equivalent to an overall density of 494 dispensers per ha. Moth captures and cluster infestation levels were compared at the perimeter and interior of vineyards receiving these different pheromone treatments and in vineyards receiving no pheromone. Orientation of male moths to pheromone-baited traps positioned at the perimeter and interior of vineyards was reduced as a result of mating disruption treatments compared with the nontreated control. These findings were consistent over both years of the study. Disruption of male moth captures in traps varied from 93 to 100% in treated vineyards, with the 494 dispensers per ha application rates providing significantly higher level of disruption than the 124 dispensers per ha rate, but only in 2007. Measurements of percentage of cluster infestation indicated much higher infestation at perimeters than in the interior of the vineyards in all three regions, but in both sample positions there was no significant effect of dispenser density on cluster infestation levels in either year. The contrasting results of high disruption of moth orientation to traps in vineyards that also had low levels of crop protection from this pheromone treatment are discussed in the context of strategies to improve mating disruption of this tortricid pes

Coping or struggling: uncovering undocumented Zimbabwean migrant's financial practices in Pretoria, South Africa

Thesis submitted in partial fulfillment of the requirements of the Master of Arts Degree In Development Studies at the University of the Witwatersrand, Department of Sociology, 2016Online resource (vii, 75 leaves)According to a report provided by Consortium for Refugees and Migrants in South Africa (CoRMSA, 2011), Zimbabwean migrants in South Africa are estimated to be between one and two million, although the actual figures remain elusive. Many of these migrants do not possess legal documentation (Tevera and Zinyama, 2002) and as a result, it is difficult for them to access financial services in the South African financial institutions, since these institutions require documentation such as valid passports with visas, proof of residence and salary slips. In light of this, undocumented migrants in South Africa are facing challenges in saving, borrowing, investing and remitting money back home. As a result, they are at risk as they may become vulnerable to loan sharks and conmen if they access financial services informally. In relation to that, the study investigates how undocumented migrants in South Africa access financial services and how this may affect their lives. The researcher found it important to conduct a first-hand investigation onto the strategies and experiences of undocumented self-employed Zimbabwean migrants who might be financially excluded in South Africa. Studying the experiences of undocumented migrants in South Africa is important as it allows for an exploration of their reactions and views about their financial exclusion or inclusion. It is also of paramount importance for us to comprehend how some people who are financially excluded worm their way into the social and economic milieu that are in large measure hostile to them. Thus the present study aims to ensure that the voices of undocumented immigrants who are financially excluded are equally heard in order for us to appreciate the harsh realities that confront them. The research focuses on undocumented self-employed Zimbabweans (street vendors, hairdressers and barber men) in the Pretoria Central Business District (CBD). The study draws on the concepts of Human Security and 'Alternative Economic Repertoires' to understand the strategies employed by undocumented Zimbabweans in South Africa in the face of financial exclusion and the insecurities that they encounter. The research follows a qualitative approach on the basis that qualitative research enables the researcher to construct meanings and interpret the behaviours of undocumented self-employed Zimbabwean migrants. In-depth interviews and participant observations were conducted in order to explore strategies in this regard. This enabled the researcher to deeply explore the experiences, views and feelings of these migrants.MT201
