In 1984 Congress amended the antidumping and countervailing duty laws, man-dating that the International Trade Commission (ITC) "cumulate" imports across countries when determining injury. We estimate that cumulation increases the probability of an affirmative injury determination by 20 to 30 percent and has changed the ITC's decision (from negative to affirmative) for about one-third of cumulated cases. We also show that the protective effect of cumulation increases as the number of countries involved increases, holding import market share constant. That is, cumulated imports have a super-additive effect on ITC decision-making.  相似文献

Conflict produces group solidarity in four phases: (1) an initial few days of shock and idiosyncratic individual reactions to attack; (2) one to two weeks of establishing standardized displays of solidarity symbols; (3) two to three months of high solidarity plateau; and (4) gradual decline toward normalcy in six to nine months. Solidarity is not uniform but is clustered in local groups supporting each other's symbolic behavior. Actual solidarity behaviors are performed by minorities of the population, while vague verbal claims to performance are made by large majorities. Commemorative rituals intermittently revive high emotional peaks; participants become ranked according to their closeness to a center of ritual attention. Events, places, and organizations claim importance by associating themselves with national solidarity rituals and especially by surrounding themselves with pragmatically ineffective security ritual. Conflicts arise over access to centers of ritual attention; clashes occur between pragmatists deritualizing security and security zealots attempting to keep up the level of emotional intensity. The solidarity plateau is also a hysteria zone; as a center of emotional attention, it attracts ancillary attacks unrelated to the original terrorists as well as alarms and hoaxes. In particular historical circumstances, it becomes a period of atrocities .  相似文献

The authors summarize the presentations and discussions contributed to the symposium International Perspectives on Career Development by members of Group 5, who considered the topic of the structure and organization of career development programs in different nations. A capsule picture of the national setting, primary goals, components, objectives, and implementation strategies is presented. Papers fell largely into 4 categories: national programs with several components; large, but more specific programs, serving a national population; smaller programs serving diverse populations; and focused programs. One theme emerged strongly from virtually every presentation: There is a gap, often profound, between policy or vision and reality. Although every nation about which participants heard had laudable policies and had made genuine attempts to assist its people with life career development, many individuals do not have access to quality, or even any, services.  相似文献

In this article I review the psychotherapy outcomes literature as it pertains to the Dodo hypothesis. This is the proposition that the effects of psychotherapy are due to common factors rather than specific techniques. A variety of sources provide substantial empirical support for the Dodo hypothesis. I conclude that CBT and medication do not appear to be any better than other methodologies for the treatment of psychological distress. I look at some of the criticisms of the Dodo hypothesis. I suggest that the major themes that emerge from the literature as it stands are conclusions that would be immediately obvious to most clinicians. Further, the utility of specific techniques has not been ruled out, due to some serious conceptual flaws in efficacy trials. I suggest that there are a number of ways for family therapists to survive in an evidence‐based world. One is to point out to champions of evidence‐based practice just how flimsy their claims are. Another would be to advocate for pluralism and to practise and conduct research under the aegis of a contextual philosophy.  相似文献

The total area of built-up land in Canada is estimated, for the first time, and divided into two categories: the extent of all large urban areas, and the extent of all small urban areas. The agricultural quality of land urbanized between 1966 and 1976 is also estimated. Contrary to expectations, this area is small compared with the entire stock of land with agricultural capability. Small settlements, however, are expanding rapidly and have relatively generous space standards. The aggregate effect of this rural urbanization on Canadian agricultural production is not currently monitored, and a redirection of policy and analytical attention towards the small settlements is suggested.  相似文献
