Rural West Africans confront a challenging array of circumstances in pursuit of their livelihoods, which are negotiated through repertoires of knowledge, skill, wisdom and information that are held individually, communally or as the prerogative of experts. Of some significance is timing: finding the most effective or propitious moment for action. On the farm, anticipating the beginning and progress of the rains is crucial and sought through the empirical observation of natural phenomena, or as in northwest Nigeria additionally through agricultural star calendars and almanacs by Muslim clerics. Furthermore, some clerics use divination to identify propitious moments for their clients whereby they may achieve success in non-farm jobs and businesses that are an integral part of rural livelihoods. Taking action to achieve particular outcomes on and off the farm raises issues about local people's understanding of the physical world and their place within it, and the power of religion and the supernatural. An appreciation of such matters would appear to be crucial for those from the scientific and technological North who may be attempting to transform African societies.  相似文献

ABSTRACT

This article examines the centrality of mathematics and scientific thought in the sociocultural, human and intellectual development of a sampling of African societies. Evidence is presented which refutes the theory that Africans had no ‘intelligible sense of numeracy’ before contact with the West, and demonstrates that the propagation of this myth was part of the larger colonial project to marginalise and ‘other-ise’ African knowledge systems. Tracing Africa's early contributions to mathematics and scientific thought forces a shift from the standard Western-based approach to pedagogy in this field. It renders a subject that is perceived and presented as alien to African culture, more accessible to African learners. And ultimately, acknowledging the long history of mathematics and scientific thought in Africa is a step in foregrounding African epistemologies in knowledge production, human and social development and towards the realisation of the African Renaissance.  相似文献

ABSTRACT

This article utilises the same epistemic objects, particular indigenous medicinal plants of the Cape region, to explore the gamut of epistemologies in contested, dynamic tension in the early Cape Colony: That of the frontiersman, the Khoikhoi, the Sonqua or Sankwe, and the slave. Drawing on a transdisciplinary set of literatures, the article puts Africana studies, the study of indigenous knowledge systems, and social studies of science and technology in wider conversation with each other, and argues for the adoption of an epistemic openness, methodologies which ‘braid’ seemingly separate strands of social history and differing knowledge practices, and cross-border collaboration among scholars of African and African diasporic knowledges. The findings and interpretation suggest new ways to view the ‘multiplexity’ of early indigenous southern African botanical, therapeutic and ecological knowledges, as well as the necessity for rethinking both the construction of colonial sciences and contemporary concerns about indigenous knowledge, biosciences and their 21st century interaction.  相似文献

Abstract

This article addresses the role of the university and institutions of higher learning in carrying out the mandate of the World Conference against Racism, Racial Discrimination, Xenophobia and Related Intolerance (WCAR), held in Durban, South Africa in 2001. The active contribution of the university is anticipated in Article 98 of the Programme of Action published in the Report of the World Conference (2001), which clearly states:
We emphasize the importance and necessity of teaching about the facts and truth of the history of humankind from antiquity to the recent past, as well as of teaching about the facts and truth of the history, causes, nature and consequences of racism, racial discrimination, xenophobia and related intolerance, with a view to achieving a comprehensive and objective cognizance of the tragedies of the past.  相似文献

This study focuses on one often overlooked political communication-based media effect, intramedia mediation, and the indirect effects that stem from relationships that exist among various forms of media use. Data from a 2000 national Annenberg election panel survey are used to assess a series of relationships between television and newspaper public affairs use and how these forms of media consumption affect citizens' knowledge of presidential campaign endorsements. The indirect effects that stem from the relationships that exist among these two forms of media use reflect the cumulative and complementary functions of mass communication consumption across time. An analysis of intramedia mediation in coordination with the study of the direct effects of public affairs media use on this study's outcome variable produces substantially larger overall effects for both forms of news use. Thus, the study of intramedia mediation contributes to a better understanding of the full range of media influences on a given outcome variable over the course of a political campaign. Ramifications of these findings are outlined and future lines of research summarized.  相似文献

Recent evidence supports the important political role that political network size and distribution plays at both the individual and system levels. However, we argue that the evidence is likely stronger than the current literature suggests due to network size measurement limitations in the extant literature. The most common approach to measuring political network size in sample surveys—the “name generator” approach—normally constrains network size measurement to three to six individuals. Because of this constraint, research often undercounts individual network size and also leads to a misrepresentation of the distribution of the underlying variable. Using multiple data sets and alternative measurement approaches, we reveal that political network hubs—individuals with inordinately large network sizes not captured by name generators—exist and can be identified with a simple summary network measure. We also demonstrate that the summary network size measure reveals the expected differences in communicative, personality, and political variables across network size better than name generator measures. This suggests that not only has prior research failed to identify network hubs, but it has likely underestimated the influence of political network size at the individual level.  相似文献

Abstract

Both the product and the process of city planning have been shown to have an influence on mental health. This paper presents a model of the process through which community design characteristics influence mental health. The model emphasizes the importance of local social interaction and physical stimulation, as well as adjustment mechanisms used to dampen stress resulting from undesirable levels of interaction and stimulation. The research on the relationship between four community design characteristics and social interaction, stimulation and mental health is then reviewed. An argument for the importance of citizen participation is also presented, stressing the influence of participation on both sense of control and the development of social support. Commonly employed participation techniques, however, differ in their ability to affect support and control. Neighborhood council programs are identified as having the greatest potential for influencing sense of control and social support. Finally the obstacles to improving community design and specific recommendations for the prevention of environmentally induced mental health problems are presented.  相似文献

Abstract

Over the past 15–20 years, the margins of industrial classifications, corporate balance sheets and GDP have been altered to capture knowledge as a new category of value. This has resulted in the institutionalization of categories such as an information economy (1997), intangible assets (2001) and, most recently, a knowledge-adjusted GDP (2013) in these calculating technologies. By harnessing knowledge as a manageable and valuable object, these shifts are responding but also contributing to the concept of a knowledge economy. This paper investigates the conditions necessary to anchor these new categories of value. The analysis attends not only to the changing rules and regulations, but also to the rhetorics of visibility/invisibility, materiality/immateriality, and measurability/immeasurability used to make a case for these transformations.  相似文献

ABSTRACT

Science and technology have a major role to play in current and future developments on the African continent as a whole. With the vast array of developmental challenges, current thinking needs to be expanded, so that technologies provide increased and enhanced solutions, such that African scientists produce an African response to the very many shared challenges affecting Africa – both as individual nations and as regards African people collectively. Key to developing an integrated science and technology network, within and across nations, is firstly to understand the extent of research and development (R&D) currently undertaken within individual territories and on the continent as a whole. In light of this, the article examines the value and importance of national surveys of research and experimental development undertaken in Africa. Within the Southern Africa Development Community (SADC), many member states now have dedicated departments overseeing state science and technology (S&T) development initiatives. South Africa has the most developed science and technology system on the continent. In recent years, other SADC countries like Mozambique, Botswana and Namibia have initiated projects to measure R&D activities within their territories. Despite this, further North, R&D measurement on the continent is uncommon, both as a result and as a cause of underdevelopment.

The article explores the limited data from selected African R&D surveys in an attempt to understand measurement issues that exist and to detail the value and importance of mapping S&T systems and their applications to developmental issues in Africa. In countries like Algeria, Angola, Burkina Faso, Cameroon, Egypt, Ethiopia, Gabon, Ghana, Kenya, Lesotho, Malawi, Mali, Nigeria, Senegal, Tanzania, Uganda and Zambia, where S&T systems exist, effective means of measurement need to be established, so that the power of these systems can be harnessed, shared and exploited to benefit the African people. To this end, the African Science, Technology and Innovation Indicators (ASTII) initiative was set up at a meeting in Addis Ababa with the aim of delivering a survey of these countries’ R&D output and potential. This is eagerly awaited by the African S&T community.

At the forefront of African R&D measurement is the South African national R&D survey, administered by the Human Sciences Research Council (HSRC). Being an established survey, the South African team is often called upon by other African nations to support the setting up of surveys. The HSRC also trains visiting African scientists in the delivery of accurate and reliable R&D survey data. This article will, for the first time, present detailed results of the most recent South African national R&D survey (2008/2009), together with a trend analysis of historic South African R&D surveys.  相似文献

The literature that explores relationships between lay and professional stakeholders in community participation generally suggests that professionals perceive five main difficulties in working with lay people: it is unnecessary within democracies; lay people lack expertise; they are not representative; there is commonly a lack of trust, and decision-making is made more complex. In respect of spatial planning in South West England, from survey evidence these difficulties are not so apparent except in respect of complex decision-making. It is likely that the variation between the literature and the survey is influenced by the longer heritage of community participation in the spatial planning process in England, than in most other local authority services.  相似文献
