Whereas the impact of trade relations on conflict has been studied extensively, this is not the case for the impact of international migration. The latter might influence the size of expected costs and benefits, and hence the likelihood of military conflict between countries. In this paper, we discuss the channels through which bilateral migration can affect the prevalence of interstate military conflict. We then estimate migration’s impact on conflict using bilateral panel data between 1960–2000. We find evidence of a positive and robust impact of South-North and South-South migration on the occurrence of conflict. These effects are even larger when we control for potential endogeneity using a GMM approach. 相似文献

Children's responses to interpersonal obstacles and the relationship of these responses to social competence were investigated using the Social Problem Situation Analysis Measure. In this procedure, children respond to standard vignettes and then have their initial response negated by the examiner. The data showed that indices of problem-solving skills instandard andobstacle situations were indeed complementary. Problem solving in response to obstacles was the strongest predictor of self-concept and teachers' ratings of studients' adjustment. Expectancies in standard situations were most predictive of behavioral problem solving and social isolation. The discussion emphasized implications for theory and research into the way in which social problem solving under obstacle conditions relates to different indices of social competence.This study was supported in part by grants to the first author from the William T.

Abstract: In the ongoing Canadian debate on confederation, variations across the country are almost invariably viewed as conditions that must be removed or at best tolerated. This paper provides an alternative view and model of confederation that builds on portfolio notions of diversification. Here, instead of seeing regional differences as barriers to a strong confederation, we envision building solidly on these differences and encouraging regions to differentiate themselves. Canada's diverse regions might then realize futures that are most appropriate to their resource endowments and human aspirations and that at the same time improve the economic growth and growth-volatility characteristics of the nation as a whole. Regions might pursue their comparative advantages rather than having to forego their distinctness in striving for a “national mean” - a mean all too frequently defined by values at the centre of economic and political power. The ensuing discussion expands this argument and applies it using two specific examples: securities regulation and housing policy. The paper concludes with some suggestions for instituting a more differentiated, diversified and decentralized form of confederation. Sommaire: Dans le cadre du debat perpetuel sur la confédération au Canada, on con-sidère presque toujours que les variations qui existent à travers le pays doivent être éliminées ou, au mieux, tolérées. Dans cet article, on présente un autre modèle de confédération qui s'inspire de la notion de diversification du portefeuille. Au lieu d'envisager les differences régionales comme autant d'obstacles s'opposant à une confédération forte, on veut bâtir du solide sur ces differences et encourager les régions à se différencier entre elles. Les régions variées du Canada seraient alors à même de suivre le cherninement le mieux adaptéà leurs richesses naturelles et aux aspirations de leurs populations, tout en améliorant les paramétres de croissance et de volatilité de la croissance de la nation toute entiére. Les régions poursuivraient alors leurs avantages comparatifs, au lieu d'abandonner leurs traits distinctifs pour tendre vers une moyenne, nationale trop souvent tributaire de valeurs situées au centre du pouvoir économique et politique. On élargit ensuite cet argument et on l'applique au moyen de deux exemples concrets: la réglementation des valeurs mobilières et la politique sur le logement. En conclusion, l'article offre quelques suggestions pour quel'on adopte une confédération plus différenciée, plus diversifiée et plus décentralisée. 相似文献

Manual recovery of spray paints from textiles using a microscope, the routine method in many laboratories, is often laborious. Beating the clothing with a plastic rod, the routine method used for recovery of glass traces within the authors’ laboratory, is proposed as an alternative. The efficiency of the method was evaluated by spray tests with fluorescent paint. In these tests, paint particles in the acquired debris samples, as well as those remaining on the textiles, were investigated. The results show that beating is an efficient way to recover and concentrate paint particles. A good efficiency for jeans fabric and rough knitwear is reported. The results appeared to be less satisfactory for smooth woven fabric. Application of the method in casework was effective for graffiti paints as well as for flaked car paint. 相似文献
