The paper illustrates the results of a correlation study focusing on linguistic variation in an Italian region, Tuscany. By exploiting a multi-level representation scheme of dialectal data, the study analyses attested patterns of phonetic and morpho-lexical variation with the aim of testing the degree of correlation between a) phonetic and morpho-lexical variation, and b) linguistic variation a...

Geographic Proximity, Trade and International Conflict/Cooperation This paper examines the interactive effect of distance and trade on international conflict and cooperation. The effect of geographic distance depends on trade, while the effect of trade varies with geographic distance. Trade reduces conflict to a greater extent when dyads are geographically close, but has a greater effect on coo...

The research enterprise increasingly involves multidisciplinary collaboration, sometimes over geographic distance. Technological advances have made these collaborations possible, and the history of past innovations suggests these collaborations are desirable. Yet multidisciplinary projects can carry high coordination costs. This study investigated how collaborations address disciplinary differe...

Both the characteristics of immigrants and the origin-countr...

In this paper it is tested which of the various alternative approaches for constructing knowledge spillover pools suggested in existing literature measures the extent to which a rm can costlessly receive external knowledge best. Since knowledge spillovers are unmeasurable, a `goodness of t' measure is constructed using innovation survey data. It turns out that measures of the uncentered correla...

This article addresses the perceptual identification of French regional accents by listeners from the Paris region and Belgium. It is based on the geographical localisation of about thirty speakers from seven French-speaking areas: Vendee (West of France), Languedoc (South of France), Alsace (East of France), Romand Switzerland, East, Centre and West of Belgium. Contrary to the speake bracket (...

Most research on family interventions of children with autism has focused on the role of the mother, and little is known about the effects of training fathers. Through a series of National Institutes of Health– funded studies we have demonstrated treatment success by focusing on fathers who are trained at home. Although our research has been successful, this work introduces questions related to...
