    Get PDF
    Mercury 199 ions confined in an RF quadrupole trap and optically pumped by mercury 202 ion resonance light are investigated as the basis for a high performance frequency standard with commercial possibilities. Results achieved and estimates of the potential performance of such a standard are given

    The provision of distance education within the HE sector - some areas for concern

    This paper presents a summary of the findings of a recent survey of the way in which UK higher education institutions (HEIs) are offering distance education (DE) courses, the types of courses being offered, and their modes of delivery. From analysis of the findings of this survey, it is apparent that the emphasis of HEIs is very much on the exploitation of available teaching technology in the delivery of DE courses. However, teaching at a distance is quite different from face-toface teaching, and the evidence suggests that many HEIs fail to implement any meaningful academic staff training for the new role of DE tutor. The authors consider the difficulties this presents to academic staff who are required to move from face-to-face teaching to online facilitating. The paper concludes with an examination of the current provision of staff development and training within UK HEIs and suggests the type of academic staff training required if DE courses are to become truly core activities

    The Evolution of an Industrial Cluster in China

    We use two rounds of surveys, in 2000 and 2008, in the Zhili Township children’s garment cluster in Zhejiang Province to examine in depth its evolution. Firm size has grown on average in terms of output and employment, and increasing divergence in firm sizes has been associated with a significant increase in specialization and outsourcing among firms in the cluster. Although initial investments have more than tripled, they remain low enough so that formal bank loans remain an insignificant source of finance. Accompanying lower entry barriers, there have been an increasing number of firms in the cluster, which have driven down profit and bid up wages, particularly since the year 2000. Facing severe competition, more firms have begun to upgrade their product quality. By the year 2007, nearly half of the sampled had established registered trademarks and nearly 20 percent had become ISO certified. Declining profit ratios to initial investment and stagnant TFP imply that the future of this industry is likely to rest on using more advanced technology and higher ratios of capital to labor, which imply increases in firm size and initial investment. Thus traditional sources of finance that do not require honest, efficient, and transparent courts are likely to fade as the need for improved legal and financial institutions become critical factor influencing China’s growth prospects.
