Internationally there has been concern about the direction of technical education and how it is positioned in schools. This
has also been the case in Malawi where the curriculum has had a strong focus on skills development. However, lately there
has been a call for enhancing technological literacy of students, yet little support has been provided for teachers to achieve
this goal. This paper reports from a wider study that looked at teachers’ existing views and practices in technical education
in Malawi. The article focuses on the findings from interviews that were conducted with six secondary school teachers to find
out about their understanding of the meaning and rationale for technical education. It is also discussed how the teachers
view technical education as involving skills development for making things and their thoughts on the benefits of such knowledge.
It is argued that teachers’ views about technical education were strongly linked to the goals of the curriculum vacationalization
policies adopted at the dawn of political independence. Besides skills training they saw the potential to impart thinking
skills related to design and problem solving, and the need for essential pedagogical techniques to support learning in technical
education. Examination requirements, inadequate opportunities to conduct practical activities and a lack of supportive policy
were seen as limiting factors. This article claims that teachers’ views were shaped by their expectations and beliefs about
the nature of technical education and what they perceived students may gain from such learning. Their views were also influenced
by contextual factors which may have implications on reforms towards broader notions of technology education. 相似文献

This paper reports on a professional development that was designed and implemented in an attempt to broaden teachers’ knowledge of the nature of technology and also enhance their technological pedagogical practices. The professional development was organised in four phases with each phase providing themes for reflection and teacher learning in subsequent phases. On-going support, reflection and feedback underpinned the professional development processes to enhance teachers’ prospects of putting aside old traditions and culture to implement new practices in their classrooms. The teachers collaboratively explored new concepts through readings of selected scholarly papers, making presentations of their views generated from the readings and engaging with peers in discussing learning, curriculum issues and concepts related to the nature of technology and technology education. A qualitative analysis of the teachers’ journey through the phases of the professional development showed the teachers’ enhanced knowledge of technology and technology education. However, their classroom practices showed technological pedagogical techniques that reflected their traditional strategies for teaching technical subjects. It is argued that although the teachers’ conceptualisation of learning in technology was still fragile at this point, attempts to shift teachers’ beliefs and practices require deep theoretical grounding and transferring that into technological practices. A professional development built on existing ideas and context helps expand the teachers’ views about the nature of technology and technology education. 相似文献

The purpose of this study was to determine the elements motivating comprehensive school students to study technology education. In addition, we tried to discover how students' motivation towards technology education developed over the period leading up to their school experience and the effect this might have on their future involvement with technology. The research was carried out as a qualitative case study and the material was collected through individual theme interviews. The study group consisted of four 15 to 16-year-old students, each representing a totally different case of motivation towards technology education. In choosing individuals for the study the main criteria were gender and negative or positive motivation towards technology education. This study found that the artefact to be made in school and the student’s freedom of choice had the most significant effect on motivation. Although, we must be careful with final conclusions as the research group was relatively small. 相似文献

This paper uses recent data on both broadband availability and adoption to empirically gauge the contribution of broadband to the economic growth of rural areas of the United States over the past decade. Availability data from the National Broadband Map aggregated to county level is used in conjunction with county-level adoption data from Federal Communication Commission. Economic variables of interest include median household income, number of firms with paid employees, total employed, percentage in poverty, and the percentage of employees classified as either creative class or non-farm proprietors. A propensity score matching technique (between a “treated” group associated with various broadband thresholds and a control group) is used to make preliminary causal statements regarding broadband and economic health. Growth rates between 2001 and 2010 for different economic measures are tested for statistical differences between the treated and non-treated groups, restricting the analysis to non-metropolitan counties. Results suggest that high levels of broadband adoption in rural areas positively (and potentially causally) impacted income growth between 2001 and 2010, and negatively influenced unemployment growth. Similarly, low levels of broadband adoption in rural areas lead to declines in the number of firms and total employment numbers in the county. Broadband availability measures (as opposed to adoption) demonstrate only limited impacts, suggesting that future broadband policies should be more demand-oriented. 相似文献

This paper evaluates the effectiveness of the private sector maize marketing system in Malawi using threshold autoregression models. Two dimensions of maize market performance are evaluated: (1) inter-regional trade and spatial price transmission; and (2) storage and seasonal price relationships. In both cases, threshold autoregression models which account for nonlinearities predicted by economic theory are applied. Results indicate that spatial price transmission and seasonal price patterns in private sector maize markets in Malawi are generally consistent with long-run competitive inter-regional trade and storage behavior, and that in most cases shocks to long-run equilibrium are arbitraged away quickly. This suggests the private sector in Malawi is generally doing a good job of transporting maize from surplus to deficit regions and smoothing maize consumption between harvests. 相似文献

This paper describes an exploratory study of an aspect of the technological knowledge of two groups of five-year-old students in their first year at school. Their emerging understandings of the steps required to develop a new product were investigated through a series of interviews. A theoretical framework linking technological knowledge to ‘funds of knowledge’ from experiences outside the classroom supported the analysis. The data suggest that young children draw on a broad range of experiences and knowledge, often uncritically, in order to explain how things are made. They are able to transfer their understandings of the technological process from one experience to another particularly when they have the language and background experiences to support them. Of particular note however, is that they were often unfamiliar with the properties of materials and therefore unable to anticipate the processes necessary to convert raw materials into a final product. The research also highlighted some key considerations for working with young children in this area. 相似文献

The Collusive Equilibrium in a Quantity-Setting Supergame: An Application to Taiwan’s Flour Industry
This paper examines the stability of the collusive equilibrium in Friedman’s repeated game through an empirical study of Taiwan’s
flour market. We calculate the payoff streams following a deviation or adherence for each firm. The evidence shows that the
specified punishment path is credible, and could sustain the collusive allocation. 相似文献

Generalist primary school teachers often have little or no training in school subjects such as science and technology. Not surprisingly, several studies show that they often experience difficulties when teaching these subjects, in fact some primary teachers even avoid teaching them. The over all aim of this study is to contribute to new theoretical and methodological tools for the study of how teachers develop knowledge for teaching, i.e. pedagogical content knowledge (PCK). And based on this, elaborate on implications for the professional development of primary school teachers. The teachers in the study participated in a design-based research project concerning technology education in Grade 1. We were especially interested in whether the teachers displayed any habits that contributed to the development of their personal PCK. We found three significant patterns in how the teachers, together with the researcher, developed knowledge of how to teach a specific topic in technology. We argue that these patterns tell us something about the teachers’ epistemic habits in relation to the teaching of technology. The existence of these habits could help to explain how teachers with little or no experience of teaching a subject can develop relevant PCK. 相似文献

This paper applies the principles of glocalization theory to Disney’s successful adaptation in Hong Kong. Glocalization refers to the interface of the global and the local. After Hong Kong Disneyland’s lack of success within a year of its opening in 2005, Disney executives attempted to cater to the local Chinese context. From a glocalization perspective, four major changes were made: (1) reduction of prices; (2) adaptation to local visitors’ customs; (3) change of décors and settings; and (4) adaptation of labor practices. Ever since, Hong Kong Disneyland has proved successful: park attendance and revenues from growth have increased. 相似文献

This paper reviews the changes in Shuanghui’s operations after the Smithfield acquisition as well as transformations in China’s pork industries. As income grows and diets change, there has been an increasing demand for high-quality pork and more processed pork products. However, China’s swine and pork industries are still at an early stage of development as evidenced by the low market concentration, intensive use of labour, a proliferation of intermediaries, and low levels of technology. Bounded by the established consumer preferences for freshness and the status quo in the midstream and upstream segments, Shuanghui is in a slow process of upgrading its domestic operations with Smithfield’s leading brands, import of chilled and frozen pork, advanced technologies, and the vertically integrated business model after this acquisition. In particular, it remains unclear whether Shuanghui can follow Smithfield’s experience to establish stable and safe hog supplies by multiplying self-owned hog farms, maintain and expand its current contracts with large-scale commercial hog farms, or rely more on global sourcing of pork primarily from the U.S. 相似文献

Analysis of dietary patterns has largely focused on their association with diseases or risk factors, but limited research has been conducted on the heterogeneity of population dietary patterns and their adherence to international or national nutritional guidelines. As a result, the aim of this study is to identify latent dietary patterns of UK residents and to assess how well different segments comply with WHO dietary norms.To achieve this objective, the UK’s National Diet and Nutrition Surveys for 2011–12 dataset was analysed performing a latent class analysis on energy (kcals) derived from selected food groups. To assess adherence to different dietary patterns of the British population to nutritional guidelines, a traffic light system and a composite conformity index were developed to establish how well the identified segments comply with current dietary WHO norms regarding salt, free sugars, total fat, saturated fat, fruit and vegetables and dietary fibre.Results show four different segments which on the basis of heterogeneity of dietary patterns were named ‘high sugar/high fat consumers’, ‘prudent eaters’, ‘high fat consumers’ and ‘junk food eaters’. These segments show significant differences within and between groups in terms of dietary calories intakes and their adherence to WHO norms. Although ‘prudent eaters’ are closer to WHO dietary guidelines than other segments, none of the identified segments fully comply with dietary WHO norms. Policy implications of these findings are fully discussed in the conclusions arguing how current, future and potential dietary demand and supply measures affect consumers’ compliance with WHO norms. 相似文献

In this systematic review, we aim to examine the impact of women’s work in agriculture on maternal and child nutrition in South Asia. Building on previous reviews supported under the Leveraging Agriculture for Nutrition in South Asia (LANSA) consortium, and recent published literature, we include findings from new LANSA research. While mapping literature onto the gender-nutrition pathways linking agriculture to nutrition (Kadiyala et al., 2014), we also point to conceptual and methodological directions for further exploration emerging from our work. Key amongst these are a focus on seasonality, poverty, and gender relations, moving beyond both an exclusive focus on women as a unified and homogenous group, and agriculture as an unchanging and common set of activities and production processes. Our analysis suggests the need for a more contextualised approach, and for a richer cross-disciplinary framework for effectively addressing the ways in which women’s work mediates agriculture’s role in improving child and maternal nutrition in South Asia. 相似文献

We use an incentive compatible experimental auction to measure demand for a new agricultural technology, a triple layered hermetic storage bag. When used properly, the bag creates an airtight seal that reduces storage loss from insect pests and neutralizes aflatoxin contamination in stored grain. We find that demand for this new technology is highly elastic (4.3) and that the wholesaler could increase profit by lowering the price. We also find that farmers’ valuation for the bag is not significantly different based on the medium through which information about it is communicated to them, either text, audio or video messages. This suggests that practitioners should use the cheapest option for disseminating information, which is text messaging in this context. In addition, we find that farmers who have prior awareness of the bag are willing to pay 20% more on average than those previously unaware of it. In total, the highly elastic demand for the improved bags, along with the fact that prior awareness of the bag leads to higher willingness to pay, suggests that a one-time price subsidy for the new technology could spur demand and increase future adoption. 相似文献

In the business-to-business sector, the brand-owner's employees are increasingly playing a key role in the representation of individual and corporate brands at the interface with actual and potential customers. Consequently, ‘internal branding’ has recently emerged as an important issue in industrial markets. This article proposes and empirically validates a theoretically structured framework for the measurement of a new construct, internal brand equity, and identifies its determinants and consequences. The findings offer evidence for the powerful impact of a brand-oriented corporate culture on internal brand equity, and demonstrate its relationship to external brand equity. Conclusions are drawn for management practice and future research. 相似文献

Institutional environment and complementary assets: Business strategy in China’s 3G development 总被引:2,自引:1,他引:1
This paper develops a framework to assess the influences of institutions and markets on the business strategy of firms in
transition economies. We argue that regulatory systems and markets in transition economies are interdependent. Their changing
conditions will interact and influence the types of partnerships in new market entry. Using a case study approach based on
historical data and interviews, we show how China’s telecommunications industry evolved between 1987 and 2007, and led to
the development of a 3G (third generation mobile telecommunications) standard and networks. Our analysis based on the framework
explains how regulative elements and market conditions shape the strategic choices of partnerships between domestic and foreign
firms when entering China’s 3G market. 相似文献
