Gentrification is generally associated with improvements in neighborhood amenities, but we know little about whether the improvements extend to public schools. Using administrative data (from spring 1993 to spring 2004) from the third largest school district in the United States, we examine the relationships between gentrification and school-level student math and reading achievement, and whether changes in the composition of the student body account for any changes in achievement. After testing several alternative specifications of gentrification, we find that, in Chicago, gentrification has little effect on neighborhood public schools. Neighborhood public schools experience essentially no aggregate academic benefit from the socioeconomic changes occurring around them. Furthermore, they may even experience marginal harm, as the neighborhood skews toward higher income residents. For the individual student, starting first grade in a school located in a gentrifying neighborhood has no association with the relative growth rate of their test scores over their elementary school years.
Two molecular sensors that specifically recognize ADP in a background of over 100-fold molar excess of ATP are described. These sensors are nucleic-acid based and comprise a general method for monitoring protein kinase activity. The ADP-aptamer scintillation proximity assay is configured in a single-step, homogeneous format while the allosteric ribozyme (RiboReporter) sensor generates a fluorescent signal upon ADP-dependent ribozyme self-cleavage. Both systems perform well when configured for high-throughput screening and have been used to rediscover a known protein kinase inhibitor in a high-throughput screening format.
A rise in large-scale land acquisitions has been documented in the popular media and scholarly literature, but with little attention to elite actors and their motivations. In this introduction to the special issue, we expand upon commonly held understandings of the drivers of global land acquisitions to explore the complex, dynamic and sometimes contradictory motivations of elites directly and indirectly involved in land deals. Focusing on the relationships between state actors, private investors, transnational corporations and scientific experts, we outline some principal ways in which elites with diverse interests shape land negotiations. We then introduce the articles in this issue and their contributions to the literature on land deals. RÉSUMÉ La croissance des acquisitions foncières de grande échelle a fait l'objet de nombreux articles tant dans les journaux que dans les publications universitaires. Cependant, les élites qui y jouent un rôle et leurs motifs ont très peu retenu l'attention. Dans cette introduction au numéro spécial, nous élargissons les interprétations usuelles des dynamiques de l'acquisition de terres à l'échelle mondiale en explorant les motifs complexes, dynamiques et souvent contradictoires des élites directement et indirectement impliquées dans les transactions foncières. En mettant l'accent sur les relations entre les acteurs étatiques, les investisseurs privés, les sociétés multinationales et les scientifiques, nous présentons certaines des principales avenues qu'empruntent les élites, qui ont des intérêts variés, pour orienter les négociations. Puis, nous présentons la contribution que les articles de ce numéro font à l'avancement des connaissances sur les transactions foncières.
This paper draws on the work of E. P. Thompson to understand anticapitalist resistance in northern California in the 1960s and 1970s. Through an analysis of the back-to-the-land movement in a region I call “Claytown,” I show how the making of a rural moral economy was in part enabled by the presence of a nascent marijuana industry. However, whereas a relatively small-scale marijuana industry helped forge anticapitalist resistance in the 1960s and 1970s, this industry has become a form through which values of capitalist political economy are being instantiated and reasserted. I situate my ethnographic analysis within a broader historical and legal framework to show how a contemporary moral economy is made and increasingly unmade in the context of late capitalism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
