Livelihoods, Land and Political Economy: Reflections on Sam Moyo’s Research Methodology

This article focuses on the methodological lessons from Sam Moyo’s scholarship. Sam’s research is characterised by a combination of detailed empirical investigation, deep knowledge of the technical and practical aspects of agricultural production and farming livelihoods, and bigpicture political economy analysis and theory. Sam’s method is an insightful contemporary application of the method originally set out in Marx’s Grundrisse. Many contemporary explorations of agrarian political economy fail to sustain the important tension and dialectical debate, between diverse empirical realities and their ‘multiple determinations and relations’ and wider theorisation of the ‘concrete’ features of emergent processes of change. The implications of Sam’s methodological approach for the analysis of Zimbabwe’s land reform are discussed, especially in relation to the land occupations and the politics of agrarian reform since 2000

Demographic transformation and the influence of eleven selected socio-demographic variables on the face validity of an engineering English for specific purposes approach at a South African university

In English for Specific Purposes (ESP), as accountable education, face validity, which could be an undesirable “negative” or a desirable “positive”, is one of the ways in which we determine the learners’ attitudes toward, and probable consequent motivation for, ESP learning programmes. In this study, we sought to explain the reactions of the 226 first year Engineering student respondents to Likert items by their sociodemographic characteristics. We measured and classified as an undesirable “negative” (if the mean was < 3.50), or a desirable “positive” (if the mean was ≥ 3.50), the face validity generated by eleven sociodemographic characteristics for an ESP approach employed in the design and delivery of a compulsory ESP module (Engineering Communication) at a university in South Africa’s Gauteng Province. We subjected the data to statistical significance testing with the ANOVA suite of inferential statistics to identify statistically significant relationships between the sociodemographic variables and the face validity variables, of which 20 were confirmed, and then measured the variance (influence) in the latter that could be associated with the former. The aggregate influence explainable by the sociodemographic variables was an eta2 of .908 (90.8%), of which High School Type (19.8%) recorded the most, and Engineering Work Experience (1,7%), the least. Whereas, Race was associated with the most “negative” influence, the Black1 and White groups were practically indistinguishable in attaining unequal, but “negative”, scores. When we compared the sample demographic statistics to available institutional and national statistics to check for demographic transformation, the statistics suggested that the research university was transforming demographically at a fast pace, given its history. &nbsp

Practicality Of Exemplary Curriculum Implementation Materials: The Case Of A Chemistry Module In Science Education In-Service Teacher Training Programme

A ZJER investigation into the practicality of a Chemistry module.This paper reports on a research study that investigated the practicality of a chemistry module. Practicality was with respect to two intentions of the module, i.e. to bring about learner centred teaching and learning as well as teaching subject content in context. The two changes were directly related to the need to bring about teaching with understanding at advanced level. As such, the module was written with the intention to exemplify the necessarily pedagogic changes as discussed by teachers at workshop level to classroom level. In light of the above, this paper describes a case study that involved two teachers at two different schools teaching chemistry using the module. Classroom observations by two researchers as well as student and teacher interviews were employed as data gathering procedures. It was found that 'contextualization’ of subject content improved the quality of dialogue among students as well as between teachers and students. There was also a change in classroom interactions towards more student involvement

The resilience of indigenous knowledge in small-scale African agriculture: key drivers

The successful use of indigenous knowledge (IK) in development practice in rural Africa over the last couple of decades has proved to be elusive and disappointing. Using empirical field data from northern Malawi, this study suggests that the two key drivers for farmers in this area are household food security and the maintenance of soil fertility. Indigenous ways of knowing underpin the agricultural system which has been developed, rather than the adoption of more modern, ‘scientific’ ways, to deliver against these drivers. Such IKs, however, are deeply embedded in the economic, social and cultural environments in which they operate

Economic impacts of cassava research and extension in Malawi and Zambia

This paper estimates the economic impacts of cassava research and extension in Malawi and Zambia over the period 1990-2008. The data come from sample household surveys, planting material production records, and a series of cassava improvement experiments conducted in the two countries. Past investments in cassava improvement have led to the development and release of a good number of high-yielding and cassava mosaic virus disease (CMD)-tolerant cassava varieties. The results show relatively higher adoption rates for the CMD-free local varieties compared to CMD-tolerant varieties that have been released in the two countries. The adoption of new varieties has been low and slow largely due to the fact that most of these varieties lacked the consumption attributes highly valued by farmers. The multiplication and distribution of CMD-free planting materials of the recommended local varieties led to greater adoption, but infection with CMD three to four years after adoption meant that the yield gains and economic benefits could not be sustained. Nevertheless, the multiplication and distribution of clean cassava planting materials generated a modest rate of return of 24%, which is actually consistent with an earlier rate of return estimate of 9 to 22% for cassava improvement in developing countries. Analysis of the ex ante impacts of current and future investments in cassava improvement shows that cassava improvement research that focuses on the development and dissemination of varieties with highly preferred consumption and industrial attributes would yield a greater rate of return of 40%

Cross sectional sero-epidemiological prevalence of poliovirus antibodies post immunization with three doses of TOPV

A CAJM study on the polio virus after immunization of infants in selected provinces of Zimbabwe.A cross-sectional sero epidemiological study to detect the presence of antibodies to polio virus types 1,2 and 3 was undertaken. A total of 437 infants with an average of 40 subjects per province was enrolled in this study. All the subjects had completed the three doses of TOPV. Blood samples were aseptically collected by heel pricking on calibrated filter papers and immediately transported to the laboratory for processing. In the laboratory, standardized techniques were used to detect neutralizing antibodies to polio virus. Antibodies with a titre of 1:32 were detected in all studied subjects. Some infants developed litres as high as 1:1024. However, polio virus type 3 showed a higher antibody titre than the other two types. Differences in titres were observed from province to province

Algorithm for solutions of nonlinear equations of strongly monotone type and applications to convex minimization and variational inequality problems

Real-life problems are governed by equations which are nonlinear in nature. Nonlinear equations occur in modeling problems, such as minimizing costs in industries and minimizing risks in businesses. A technique which does not involve the assumption of existence of a real constant whose calculation is unclear is used to obtain a strong convergence result for nonlinear equations of (p, {\eta})-strongly monotone type, where {\eta} > 0, p > 1. An example is presented for the nonlinear equations of (p, {\eta})-strongly monotone type. As a consequence of the main result, the solutions of convex minimization and variational inequality problems are obtained. This solution has applications in other fields such as engineering, physics, biology, chemistry, economics, and game theory.Comment: 11 page

Perceptions and experiences of senior managers regarding organisational transformation and change within eThekwini Municipality.

Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2013.This study explores the perceptions and experiences of senior managers regarding organisational transformation and change. To achieve this objective, a qualitative methodology was undertaken and twelve open-ended questions were formulated for the study. Twenty-two semi-structured interviews were conducted. A non-probability sampling technique was utilised, along with snowball sampling and judgement sampling methods to select participants for the study. The sample consisted of twenty-two senior managers from different Units and Departments within the eThekwini Municipality. The data collected were then qualitatively analysed using thematic analysis. The findings of the study were presented under key themes that had emerged during the study. The main findings of the study showed that the municipality had radically transformed in response to the new political dispensation in South Africa, as of 1994. The study highlighted the general consensus amongst senior managers that fundamental transformation of the Municipality was imperative. The participants of the study expressed the view that the former municipal organisation had become misaligned with its environment. It was therefore imperative to ensure fundamental transformation of the municipality. Most senior managers, however, felt that the transformation process was poorly managed. These negative views were attributed to, inter alia, the long period of transformation, poor change management, and lack of a clearly articulated organisational culture coupled with some poorly implemented systems. Although negative views were expressed with regard to the transformation process, most senior managers were satisfied with their specific jobs. This surprising finding was attributed to positive personality characteristics and humanistic-existential perspectives that most senior managers were found to possess. Existentialists believe in people taking responsibility for their lives and the humanists stresses the importance of self-actualisation
