It appears that programme development in technology education is emerging from an atheoretical perspective. This could be attributed to the absence/neglect of conceptual frameworks (philosophical underpinning) in the development of programmes in technology education. This article explores the role of the content dimension of the 'essential features' of technology and technology education in OBE (Outcomes Based Education) related programme development. An instructional programme was developed using criteria derived from the essential features of technology and technology education. In order to gauge learners' experience, in relation to these essential features, a qualitative case study involving 20 learners was undertaken at a College of Education. Engagement with theprogramme proved to be an empowering experience for the learners who had hitherto not had the opportunity to experience a formal programme in technology education. Although it could not be proved conclusively that cognitive development had occurred, positive inter-dependence,shared responsibility, social skills and enhanced learning were evident. The study has shown that criteria derived from the 'essential features' of technology and technology education could serve as a reliable yardstick to measure the extent of learning in relation to these essential features 相似文献

This essay reviews the international human rights standards that the Human Rights Watch Report uses as standards for judgment, summarises with some commentary the Report’s major findings and recommendations, comments more fully on certain findings and recommendations, and, in conclusion, raises several issues that need to be addressed given the state of freedom of association and other related human rights in the USA. 相似文献

We use a factor model and elastic net shrinkage to model a high-dimensional network of European credit default swap (CDS) spreads. Our empirical approach allows us to assess the joint transmission of bank and sovereign risk to the nonfinancial corporate sector. Our findings identify a sectoral clustering in the CDS network, where financial institutions are in the center and nonfinancial entities as well as sovereigns are grouped around the financial center. The network has a geographical component reflected in different patterns of real-sector risk transmission across countries. Our framework also provides dynamic estimates of risk transmission, a useful tool for systemic risk monitoring. 相似文献

World demand for refractory products—heat-resisting ceramic materials used in metal refining, glass making, and other high-temperature industrial applications—will be slowing down considerably from an annual rate of 10.8 percent during 2002–07 to 3.5 percent during 2007–12. Such slower growth reflects many factors, but is due primarily to: unsettled economic conditions; better efficiencies in steelmaking (which accounts for about half of all end uses of refractories); and the preference of end-users for maintenance rather than new facilities. The four key markets or end uses for refractory materials are: iron and steelmaking; other metal-making; nonmetallic materials such as glass; and an all-other category. In 2007, world refractory demand was 38.1 million metric tons valued at $22.9 billion; the corresponding figures for 2012 are projected at about 45.2 million metric tons valued at $28.5 billion. The Asia-Pacific region accounted for about 45 percent of total weight in 2007; its share by 2012 should rise to about 69 percent, with China becoming the dominant producer and consumer of refractory materials. 相似文献

World demand for heating, ventilating, and air-conditioning (HVAC) equipment is expected to rise in absolute terms during the current five-year period, but the rate of growth is slowing. However, growth is still in excess of that recorded by both global building construction expenditures and world gross domestic product. In 2007, $63.1 billion was spent on HVAC. The Asia-Pacific region now accounts for about 45 percent of the total. The two major categories of HVAC are cooling equipment, which accounts for 71 percent of the total, while heating equipment is responsible for the remaining 29 percent. The commercial market dominates the residential market by a ratio of 65:35. There are hundreds of suppliers around the world, but the eight leading firms have about 50 percent of the market. 相似文献

Growth in the current-dollar sales of agricultural machinery and equipment was almost six percent per
annum during 2000-2005.1 This was much faster than the 2.6 percent growth for agricultural output and the 1.2 percent rate
for population in the same period.
