AbstractIn Great Britain and the United States common developmental issues have resulted in the evolution of two very different models of school library provision. In the United States, school libraries are integrated media centers, separate from public library influence, staffed by specialists with dual training in teaching and librarianship, and dedicated to an educational mission. British school libraries are contested terrain with two patterns of staffing, support by Public Library Services, and incomplete formulation of mission and rationale. This article discusses five factors which have facilitated or retarded school library development in the two countries (standards, staffing and certification, government support, rationale, professionalization) and generalizes about development factors and the successful promotion of school libraries. 相似文献

Skin and core tissue cooling modulates skeletal muscle oxygenation at rest. Whether tissue cooling also influences the skeletal muscle deoxygenation response during exercise is unclear. We evaluated the effects of skin and core tissue cooling on skeletal muscle blood volume and deoxygenation during sustained walking and running. Eleven male participants walked or ran six times on a treadmill for 60 min in ambient temperatures of 22°C (Neutral), 0°C for skin cooling (Cold 1), and at 0°C following a core and skin cooling protocol (Cold 2). Difference between oxy/deoxygenated haemoglobin ([diffHb]: deoxygenation index) and total haemoglobin content ([tHb]: total blood volume) in the vastus lateralis (VL) muscle was measured continuously. During walking, lower [tHb] was observed at 1 min in Cold 1 and Cold 2 vs. Neutral (P?0.05). Lower [diffHb] was seen at 1 and 10 min in Cold 2 vs. Neutral by 13.5 ± 1.2 µM and 15.3 ± 1.4 µM and Cold 1 by 10.4 ± 3.1 µM and 11.1 ± 4.1 µM, respectively (P?0.05). During running, [tHb] was lower in Cold 2 vs. Neutral at 10 min only (P = 0.004). [diffHb] was lower at 1 min in Cold 2 by 11.3 ± 3.1 µM compared to Neutral and by 13.5 ± 2.8 µM compared to Cold 1 (P?0.001). Core tissue cooling, prior to exercise, induced greater deoxygenation of the VL muscle during the early stages of exercise, irrespective of changes in blood volume. Skin cooling alone, however, did not influence deoxygenation of the VL during exercise. 相似文献

We address the question of the quality of movies produced between 1950 and 1970. A first outcome of our analysis is that the quality assessments made during the Cannes Festival, and to a lesser degree, by the U.S. Academy are short-lasting. In contrast to this, consumers seem consistent over time. There is, however, one issue on which experts agree as well as consumers: American movies dominate both in terms of commercial success and in terms of quality. There is less agreement, and sometimes there is even dissent concerning other dimensions. This does not come as a surprise and merely indicates that there is hardly a common yardstick along which the quality of a movie can be measured. Therefore, decomposing a work of art into quantifiable characteristics – even in a subjective but possibly unanimous way – would make it possible to explain the divergences between audiences and changes of appreciation over time. 相似文献

Attendant to the changing profile of the labor pool are shifts in norms and expectations that complicate worker recruitment, hiring, and retention. As labor pool, economic, and organizational characteristics change, two issues emerge: first, the growing need to efficiently coordinate available workers with the work that needs to be done, and second, strategies for organizations to use need to be developed. Leontiefs Input/Output Theory has been used to illustrate issues related to coordination of labor, and two pre-employment tests have been studied to determine the effectiveness of pre-employment testing strategies. Pre-employment test scores obtained in an expanding contract electronics manufacturing firm have been analyzed to determine the relationships that may exist between test scores and employee success. Success has been defined as performance and retention. Multiple regression and discriminant analyses revealed several statistically significant results, including a relationship between Working Safety-test scores and performance, and Job Candidate Profile scores and retention. While interesting in and of themselves, the results further suggest that variables exist, other than those studied, that arc important to the selection of successful employees. 相似文献

Organizational performance is highly influenced by how employees envision the future. To date, many scholars have emphasized the importance of an overarching future vision that unites all stakeholders, while acknowledging the presence of divergent perspectives among members. This variety in perspectives may be further complicated in organizations undergoing great stress and where the leadership has not defined and promoted a future vision to guide the content of the images of its members. Little study has explored the various types of future organizational images that exist or the nature of those images. We explore these concerns via a case study of an airline in the midst of a dramatic fight for survival. The findings both confirm the existence of multiple views for the company's future and delineate their general characteristics through a typology of imagery. We conclude with a language to use to differentiate those images for future research and offer practical implications for managing multiple future organizational images to mobilize energy and enhance performance in a more unified direction. 相似文献
