ABSTRACT We develop an objective methodology for forming large regions (called macroregions) from small regions (microregions). We observe that the aggregation of microregions in an interregional input-output model causes aggregation error in the model. Our optimal regions are those that cause aggregation error to be minimized. We apply our methodology to Canada, and we compare our optimal regions for Canada to those of Statistics Canada and to those obtained using the well-known heuristic of Kossov. Statistics Canada's regions as well as those produced using Kossov's technique are characterized by substantially greater aggregation error than are those produced with our methodology. 相似文献

This article investigates the determinants of political cleavages composing the structure of political attitudes in Jordan, Tunisia, and Yemen following the Arab Spring. Further, it tests whether political cleavages carry predictive weight on ordinary citizens’ electoral choices in general elections. Using the Sixth Wave of the World Values Survey, discriminant analysis was conducted to generate the dimensionality, type, and structure of political attitudes in the three nations. Findings suggest that the structure of political attitudes in Jordan, Tunisia, and Yemen is multidimensional: the Islamic‐Secular division, a conflict along economic policy visions and an emerging divisive dimension concerning political reform. Evidence indicates that political cleavages do not possess significant predictive power in determining voters’ choice at elections booths. This research also points to the significance of social transformation processes such as modernization and globalization in causing a shift in values among ordinary citizens in the Arab World. This research argues that in countries where the effects of modernization and globalization are higher, a weakening of the Islamic‐Secular division is witnessed. This research is important since it paves the way for further empirical analysis on political ideology in the Middle East. It shatters conjectures concluding that Arab polities are only divided by a single hierarchical dimension: Islamic‐Secular. It contributes to comparative research on the dimensionality of political ideology by showing that the Arab World is similar to the industrialized world in the dimensionality, nature, and structuration of political ideology. 相似文献

As part of a geological survey in southwest mainland New Caledonia, potsherds were recorded in the profiles at four coastal sites. Subsequent archaeological investigations at two of these sites have allowed us to diversify the ceramic data and show them to be local variants of Podtanean, Puen, and Plum ceramic types. These are characteristic of production in the southern part of the archipelago during the first millennium BC and first millennium AD. The presence of fishing sites showing no indication of permanent settlements on these seashores, and the clear absence of second millennium AD occupations related to the “Traditional Kanak Cultural Complex”, characterized by large sedentary hamlets, illustrate a significant shift in settlement patterns between the first and second millennium AD. 相似文献

Responding to the collection of articles, ‘Queering Code/Space,’ this article discusses how algorithms affect the production of online lesbian, gay, bisexual, transgender, and queer (LGBTQ) spaces, namely online dating sites. The set of articles is well timed: lesbian bars have closed en masse across the US and many gay male bars have followed suit so that online spaces fill – or perhaps make – a gap in the social production of LGBTQ spaces. I draw on Cindi Katz’s idea of ‘messy’ qualities of social reproduction and the necessity of ‘messing’ with dominant narratives in order to think about the labor, experience, and project of queering code/space. 相似文献
