The relation between domestic R&D and imports of technology is examined for 10 countries. Simple regressions revealed strong complementarity for each of the countries. Multiple regressions including GNP per capita and number of scientists and engineers were performed for the five countries with time series for all the variables. Strong complementarity was found between technology imports and domestic R&D and other variables for Japan and South Korea, weak for France, none for Germany and the US. Excluding government-financed R&D in the US resulted in a substitutive relation. Japan revealed a sharp decline in the ratio of technology payments to R&D spending; Korea is following in its steps. Complementarity appears to weaken in later stages as technology development strategies shift from dependent to imitative to autonomous or offensive technology development.  相似文献

With Bill Clinton's new reforms only a month away, the health-care system is on the operating table--and the doctors are under the knife. Americans have a love-hate relationship with physicians: they like the care that doctors provide but hold them to blame for the nation's health-care mess. NEWSWEEK looks at how the culture of medicine may change, assesses doctors' fears--and examines the brave new world of HMOs.  相似文献

Measuring School-Related Stressors in Adolescents   总被引:2,自引:0,他引:2  
Some 1620 high school students responded to 68 items that measure adolescent stressors. Thirty-five of the items were based on J. P. Kohn and G. H. Frazer's Academic Stress Scale [1(1986) An Academic Stress Scale: Identification and Rated Importance of Academic Stressors, Psychological Reports, Vol. 59, pp. 415–426] developed in the United States, while the remaining 33 items were developed from P. Strutynski's [(1985) A Survey of Queensland Year 10, 11 and 12 Student Attitudes to Schools and Schooling, State Planning Committee, International Youth Year, Brisbane] lists of the most frequently named problems of 2336 Australian high school students. Confirmatory Factor Analysis was used to test and develop a measurement model developed from an extensive review of previous scales. The High School Stressors Scale emerged from the analytic process and measures nine school-related stressors. For researchers focusing on school-related problems and stressors among adolescents, the HSSS promises to be a very useful instrument. It has sound construct and predictive validity and adequate reliability, as demonstrated by the goodness-of-fit indices the squared multiple correlations.  相似文献

"This article describes the migration context of three sets of Western democracies and then explores plausible linkages between the scale, timing, and characteristics of migration, and the substance and process of migration policies, on the one hand, and support for government, on the other. Trying to move beyond plausibility, I discuss indirect indicators of the impact of immigration on Western publics: attitudes toward immigration policy and immigrants, support for extremist parties, and acts of violence and disorder linked to anti-immigrant or racist motives."  相似文献

While most speakers at the 1996 World Food Summit expressed concern about the injustice that forces more than 800 million people worldwide to live with hunger, some sought solutions through economic and social development while others called for a more liberal marketplace. Among world leaders, only Fidel Castro raised issues and challenges that addressed some of the underlying causes of malnutrition. The Plan of Action that grew out of the Summit has only one measurable commitment, which is to halve the number of undernourished people by 2015. The other six commitments, while diluted, contain important objectives even though they give little emphasis to the underlying causes of poverty or hunger. The Summit process, however, did contribute to the fact that food-related issues are now placed higher on the world agenda because many of these issue were raised by civil service organizations (CSOs) at the Summit's parallel NGO (nongovernmental organization) forum. In fact, one of the most positive outcomes of the Summit may prove to be the increased effectiveness of the CSOs as a result of the creation of improved networks in preparation for the Summit. The CSOs contributed examples of how food security could be improved, published an active site on the World Wide Web, and challenged the statements of governments. In addition to raising trade issues, CSOs also lobbied for sustainable agriculture and agricultural biodiversity. In fact, CSOs may have to set a new action agenda for the formal sector to encourage development of new institutions and new global forums that give NGOs a place at the table.  相似文献
