International residential tourism is a recent phenomenon in the Andean area. However, in places where it has been established, rapid changes in social and economic structures have occurred. The Municipality of Cotacachi (Northern Ecuador) is paradigmatic. Having become a destination for American retirees, residential tourism has generated a sharp increase in the price of rural land and has decelerated a land market that once allowed young farmers to continue agricultural activities. Residential tourism has promoted land exchange value while sacrificing use value, threatening peasant reproduction mechanisms. 相似文献

The purpose of this article is to discuss the development of Joan Miró's aesthetics between 1915 and the early 1920s, and to offer an interpretation of a series of landscapes that he painted between 1918 and 1922, by highlighting their similarities with some of the landscapes described by Catalan writer Josep Pla in his Obra completa. Both Miró's and Pla's landscapes are situated within the context of Noucentisme and, more particularly, of Noucentisme's classicist aesthetics as defined by Eugeni d'Ors in his Glosari. 相似文献

THE CURRENTS BENEATH THE “RISING TIDE” OF SCHOOL CHOICE: AN ANALYSIS OF STUDENT ENROLLMENT FLOWS IN THE CHICAGO PUBLIC SCHOOLS 下载免费PDF全文

Existing research highlights that families face geographic, social, and psychological constraints that may limit the extent to which competition can take hold in school choice programs. In this paper, we address the implications of such findings by creating a network of student flows from 11 cohorts of eighth‐grade students in the Chicago Public Schools (CPS). We applied a custom algorithm to group together schools with similar sending and receiving patterns, and calculated the difference in mean achievement between a student's attended and assigned high schools. For all identified school groupings, we found that the students were on average moving to higher achieving schools. We also found that the movement toward higher achieving schools of the top achievement quartile of students was over twice as large as that of the bottom quartile, but that the flows of both the highest and lowest achieving student quartiles were toward higher achieving destinations. Our results suggest that student movements in CPS between the years of 2001 to 2005 were consistent with creating market pressure for improvement as well as increasing segregation by achievement. However, further research into how schools responded to those movements is required to make inferences about the level or consequences of competition generated by choice‐related reforms during that time. 相似文献

This note describes a low-cost online portal called “the Cambridge Randomizer”, which enables treatment providers to conduct random assignment themselves, while the researcher still maintains control over the entire process and the integrity of the allocation process. 相似文献10.

Vertebral artery removing constitutes a significant forensic pathology challenge. Dissection techniques during head-neck autopsy are based on anterior approach, a difficult method, which is unable to assess the transverse part of the artery. This work presents an original and simple method for dissecting vertebral arteries by a posterior approach, opening the vertebroarterial canal through the spinal canal without any special equipment. Once the spinal cord is removed, the transversarium foramens are opened by an internal cut at the pedicle and an external cut at the transverse process. This enables us to visualize vertebral arteries in its entirety. The method improves both the examination of the upper extracranial segment of the vertebral artery and the neuropathological study when arterial injury is suspected. Applying this method routinely is both feasible and useful in suspected cases of vertebral artery trauma and could contribute to assess more precisely the actual incidence of this injury. 相似文献
