This study presents a classification of political regimes as democracies and dictatorships for a set of 141 countries between 1950 or the year of independence and 1990. It improves existing classifications by a better grounding in political theory, an exclusive reliance on observables rather than on subjective judgements, an explicit distinction between systematic and random errors, and a more extensive coverage. 相似文献

Local governments represent an important moving force in promoting sustainable development policies as they make up the level of governance closest to the citizens. The aim of this article is to examine whether Italian local governments exercise de facto their vital role in fostering sustainable development policies. In particular, we analyzed municipality behavior about adopting “green management strategies.” We investigated the main factors identified in management literature which might boost the adoption of these strategies. Several implications ensue from our findings. In particular, the research provides information to improve local government attitudes toward the sustainable development challenge. 相似文献

We analyse the impact of higher food prices on rural households in Tanzania focusing on the often neglected role of households’ behavioural responses. We introduce a new framework which considers the production response jointly with substitution effects in consumption and takes into account households’ market participation choices. Taking into account behavioural responses on consumption and production can significantly alter the sign and magnitude of the welfare impact in the long run. 相似文献

The impact of phylogeographic information on mtDNA forensics has been limited to the quality control of published sequences and databases. In this work we use the information already available on Eurasian mtDNA phylogeography to guide the choice of coding-region SNPs for haplogroup H. This sub-typing is particularly important in forensics since, even when sequencing both HVRI and HVRII, the discriminating power is low in some Eurasian populations. We show that a small set (eight) of coding-region SNPs resolves a substantial proportion of the identical haplotypes, as defined by control-region variation alone. Moreover, this SNP set, while substantially increasing the discriminating efficiency in most Eurasian populations by roughly equal amounts, discloses population-specific profiles. 相似文献

In this work, a sample of 124 unrelated individuals from San Andres Island and Santa Marta City (Colombia) was studied for the nine STRs included in the AmpFlSTR Profiler kit (CSF1PO, D3S1358, D5S818, D7S820, D13S317, FGA, TH01, TPOX and vWA). Although these two populations are geographically apart, San Andres is an Island in the middle of Caribbean Sea (about 480 miles northwest the Colombian mainland) and Santa Marta City located in the coast, exact test showed no differentiation between both population samples (P=0.39445+/-0.0805). Therefore, allele frequencies and parameters of forensic interest were estimated for the global sample. 相似文献
