ABSTRACT

Over the past three decades, urban sociologists have shed light on the intensifying social inequality between the wealthiest and poorest neighborhoods in global cities; yet limited research has been done to illuminate the relationships between urban polarization and school choice (i.e., where parents choose schools for their children). This study sociospatially examines the patterns of secondary school choice in the global city of Toronto to illuminate the relationship between urban polarization and school choice. In doing so, this study combines Pierre Bourdieu’s sociospatial theory with a geographic information systems (GIS) approach. Overall, we found that popular schools and schools with specialized choice programs tend to be located in high-status neighborhoods, defined as neighborhoods with residents in the top 20% of family income, home prices, education attainment, and representation from the dominant culture. We also show that mobile students who choose popular schools or highly sought-after specialized programs tend to come from advantaged neighborhoods. Meanwhile, local students who choose a regular school in their neighborhood tend to come from low-status neighborhoods. With a new interdisciplinary approach, this study contributes to a more spatialized understanding of how social inequality and polarization account for school choice.  相似文献

The purpose of this study was to investigate the role textbooks can play on writing complexity and lexical density as a proxy for critical thinking and ultimately learning, in relation to argumentative and summative writing when integrated with a virtual reality experience. In this study, differences in writing complexity and lexical density scores were measured across four different pedagogical modalities: VR alone, VR followed by textbook readings, textbook readings followed by VR, and textbook readings alone. Adult students, recruited from non-science-based higher education programs, responded to two prompts related to content found in the VR environments and discussed in the textbooks. The authors hypothesized that exposure to a virtual marine environment prior to responding to the writing prompts would enhance both argumentative and summative writing products, when compared to participants who only had access to the textbook experiences. Participants who were exposed to the VR environment then a textbook demonstrated significantly greater writing complexity and lexical density scores than those who had access to VR alone, or access to the text alone.

Word sense disambiguation (WSD) is meant to assign the most appropriate sense to a polysemous word according to its context. We present a method for automatic WSD using only two resources: a raw text corpus and a machine-readable dictionary (MRD). The system learns the similarity matrix between word pairs from the unlabeled corpus, and it uses the vector representations of sense definitions from MRD, which are derived based on the similarity matrix. In order to disambiguate all occurrences of polysemous words in a sentence, the system separately constructs the acyclic weighted digraph (AWD) for every occurrence of polysemous words in a sentence. The AWD is structured based on consideration of the senses of context words which occur with a target word in a sentence. After building the AWD per each polysemous word, we can search the optimal path of the AWD using the Viterbi algorithm. We assign the most appropriate sense to the target word in sentences with the sense on the optimal path in the AWD. By experiments, our system shows 76.4% accuracy for the semantically ambiguous Korean words.  相似文献

Abstract

This paper tries to analyze the historical change in the Third World in its emergent stage, in the authoritarian stage and in the current democratic stage and, thereafter, find a way to revive the Bandung spirit in the current globalization context. I define the Bandung spirit as one of a ‘non‐aligned self‐helped “organization against” the dominant powerful countries’; that is, spirit of ‘anti‐predominance’. This spirit has emerged on the base of such domestic orientation and realities as economic self‐reliance, nationally integrated political regime, convergence of the state and civil society around anti‐colonialism. However, according to intensification of the Cold War confrontation on the international level and its centrifugal influence, the early Third World changed to a ‘new’ authoritarian Third World. The Third World in this stage could be characterized by an exclusive authoritarian political regime, dependent‐developmentalist economic orientation and coercively repressed and mobilized, in the top‐down way, civil society. This authoritarian Third World began to be confronted with a strong struggle from the bottom for democratization. In order for democratization of the Third World to become its true revival in the context of globalization, the following tasks should be considered. First, the democratic Third World should be a great driving force for the institutionalization of the transnational public regulatory mechanism. Second, the democratic Third World countries try to go over a kind of ‘transformed’ dependent development strategy. Third, democratization should go along with recovery of political inclusiveness and openness of the state to civil society’s demands. Thereafter, I tried to construct globalist re‐interpretation of the Bandung, by way of conceptualizing the current globalization as imperial globalization, unlike the imperialist globalization which the historical Bandung wanted to confront. I argue that the Bandung spirit of collective self‐help organizations against the newly emerging dominant order should be revived in this worse imperial globalization context. In addition, I argue that a nationalist resistance is also one component of the multiple resistances in the current imperial globalization.  相似文献

We present an engineered three-dimensional (3D) in vitro brain microvasculature system embedded within the bulk of a collagen matrix. To create a hydrogel template for the functional brain microvascular structure, we fabricated an array of microchannels made of collagen I using microneedles and a 3D printed frame. By culturing mouse brain endothelial cells (bEnd.3) on the luminal surface of cylindrical collagen microchannels, we reconstructed an array of brain microvasculature in vitro with circular cross-sections. We characterized the barrier function of our brain microvasculature by measuring transendothelial permeability of 40 kDa fluorescein isothiocyanate-dextran (Stoke''s radius of ∼4.5 nm), based on an analytical model. The transendothelial permeability decreased significantly over 3 weeks of culture. We also present the disruption of the barrier function with a hyperosmotic mannitol as well as a subsequent recovery over 4 days. Our brain microvasculature model in vitro, consisting of system-in-hydrogel combined with the widely emerging 3D printing technique, can serve as a useful tool not only for fundamental studies associated with blood-brain barrier in physiological and pathological settings but also for pharmaceutical applications.  相似文献

Using two experiments, this study aims to investigate how politically liberal or conservative message recipients respond to anti-tobacco appeals. The results show that in Study 1, respondents were exposed to a message about price policy. In Study 2, they were exposed to a message about a warning policy. In both studies, liberal participants more favorably evaluated anti-tobacco messages emphasizing feasibility rather than desirability, whereas conservative participants more positively evaluated messages emphasizing desirability rather than feasibility. Implications for policymakers and marketers are discussed.  相似文献

Research has consistently found acute mental health treatment disparities among Asian Americans. One proposed reason for the underutilization of mental health services by Asian Americans is that available services are not culturally competent. This exploratory study presents qualitative data gathered from interviews with professional counselors who serve Asian American clients. Findings revealed significant barriers to counseling due to cultural stigma and shame, suppression of emotions, and communication gaps between clients and counselors. In response, clinicians frequently made adjustments to therapeutic approaches to accommodate the cultural beliefs and practices of clients and families. Implications for practice and research are discussed.  相似文献

Using the translated contents of the National Institute on Aging (NIA)'s Aging IQ, an educational intervention was delivered to older Korean Americans. The educational program was delivered via two different modalities, Internet-based education (n = 12) and in-class education (n = 11), and the overall feasibility and efficacy were evaluated by the Reach, Efficacy, Adoption, Implementation, and Maintenance (RE-AIM) framework. A high level of completion and overall satisfaction with the program was observed in both groups. Both groups also exhibited a significant improvement in their knowledge about aging after the completion of the educational program. However, at the one-month follow-up, the Internet-based group showed a greater retention of the knowledge gained. The findings not only support the value of education on aging for older ethnic minorities but also suggest the use of the Internet as an integral modality of intervention delivery.  相似文献
