Manufacturing plant closure has been the subject of much national concern, and an extensive literature principally focused on the developed world. This study extends the findings on plant closure with an analysis of export-oriented manufacturers (maquiladoras) in Mexico, 1996–2006. The foci of this research are hypothesised variables of maquiladora closure: product manufactured (value-added), size of plant, plant location, and size of urban place. The results of a logistical regression model indicate that plant size and value-added are highly probable determinants of plant closure; large, high value-added product maquiladoras have low rates of plant closure. Maquiladoras manufacturing low value-added products have high rates of closure; however, these manufacturers also have significant numbers of surviving plants. This suggests that multiple manufacturing platforms are viable among Mexico’s export-oriented industry. The findings also suggest that much plant closure is a result of exogenous factors,exiting plants in a global search for cheap labour. Mexico, however, has a geographic comparative advantage that, for many maquiladoras, trumps wages in more distant locations.  相似文献

In the winter 1978 issue of International Security, Raymond L. Garthoff authored a seminal article outlining common fallacies in United States government estimates of enemy intentions during the Cold War. Now, given the significant changes in threat over the past 30 years, it seems appropriate to take a fresh look at fallacies – evaluating old ones and introducing new ones – in enemy intentions estimates pertaining to post-Cold War (and post-9/11) security dangers. Based on its assessment, this article concludes that the challenges to accurate intelligence assessment of enemy intentions, and the need to move away from dysfunctional standard operating procedures, have never been higher.  相似文献

The prime British objective in China during the Pacific War was the re-establishment of pre-war trade and influence and the recovery of Hong Kong. Through Operation ‘Remorse’ (1944–45) the Special Operations Executive covertly established a wide network of distributors and buyers throughout occupied and unoccupied China for high-value low-bulk goods and currencies, using the returns acccruing to buy influence, information, safety and food for Allied prisoners, subsidise politically problematic operations, and smooth the British path back into Hong Kong. ‘Remorse’ epitomised the concerns and demonstrated the methods of the British presence in China generally: a readiness to innovate and adapt, market sensitivity and a capacity for making unlikely local alliances, all held together through a strong focus on a fixed target – a secure China base for Sino-British trade.  相似文献

Three thousand, three hundred and ninety-five families, whose child attended one of 80 different day or resident summer camps for at least one week, completed customized questionnaires that measured growth from precamp to postcamp in four domains: Positive Identity, Social Skills, Physical & Thinking Skills, and Positive Values & Spirituality. Parents, children, and camp staff reported significant positive change in these four domains; more than would be expected by maturation alone. Most gains were maintained or showed additional growth six months later. Few of the camp's structural elements correlated with growth, nor did striking gender, age, or ethnicity differences emerge. The study highlights the particular strengths of camp as an educational institution and social movement and suggests that different variations of summer camp can provide potent developmental experiences.

Two features of citizen response to Congress can be taken as grounds for concern. First, Americans know relatively little about Congress, and especially about congressional procedures and policy output. Second, Congress typically emerges as the least respected political institution. Although these matters are troubling when viewed individually, more disturbing is the dilemma posed when knowledge and attitudes toward Congress are viewed in tandem. It appears that citizens who know Congress the best like Congress the least. Consequently, a sophisticated polity and a well-respected legislature seem fundamentally incompatible. This article seeks to resolve this dilemma, contending that there is nothing about knowledge per se that leads citizens to view Congress unfavorably. Rather, differences in knowledge levels alter the considerations citizens bring to bear when evaluating Congress, with the best-informed individuals constructing judgments on the basis of the most relevant Congress-specific criteria while less knowledgeable citizens employ readily available but more peripheral criteria.  相似文献

Unanimity, Discord, and the Communication of Public Opinion   总被引:1,自引:0,他引:1  
This article is concerned with the political communication of opinion that occurs through networks of associated citizens. Its primary attention focuses on opinion variance within populations and networks and how such variance affects communication among and between individuals. Particularly in the context of ambiguous or infrequent communication, people may experience difficulty in forming judgments regarding the opinions of others. In such situations, environmental priors become useful devices for reaching these judgments, but a problem arises related to the utility of these environmental priors when discord rather than unanimity characterizes the contextual distribution of opinion. The article's argument is that dyadic discussions between two citizens are most enlightening, and environmental priors least enlightening, when surrounding opinion is marked by higher levels of disagreement. The analyses are based on data taken from the 1996 Indianapolis-St. Louis study .  相似文献
