This essay examines representations of U.S.–Latino identity on the ABC television program Ugly Betty. The analysis argues that the show articulates a tension between ethnic “otherness” and cultural assimilation that symbolizes current negotiations of individual and collective identities among young, English-speaking Latinos in the United States. Furthermore, the essay argues that Ugly Betty symbolically endorses a new conceptualization of Latino identity in the United States. The conceptual framework of the analysis is the relationship between media representation and identity. 相似文献

Family‐Centered Positive Behavior Support Interventions in Early Childhood To Prevent Obesity 
下载免费PDF全文
下载免费PDF全文 Positive behavior support (PBS) strategies in early childhood, which include proactively structuring environments to support and positively reinforce healthy dietary and physical activity behaviors, are critical for preventing pediatric obesity, particularly among low‐income, ethnic minority children. Existing evidence‐based family‐centered preventive interventions effectively impact parents’ use of PBS strategies. Enhancing these programs to more directly target the key mechanisms of change specific to promoting children's healthy lifestyle behaviors could serve as the foundation for the next generation of effective protocols for preventing pediatric obesity. Two established programs that target PBS that can be feasibly implemented in a variety of service delivery systems using a multi‐tiered, adaptive approach and the next steps of translation are discussed. 相似文献

The anonymization of query logs is an important process that needs to be performed prior to the publication of such sensitive data. This ensures the anonymity of the users in the logs, a problem that has been already found in released logs from well known companies. This paper presents the anonymization of query logs using microaggregation. Our proposal ensures the k-anonymity of the users in the query log, while preserving its utility. We provide the evaluation of our proposal in real query logs, showing the privacy and utility achieved, as well as providing estimations for the use of such data in data mining processes based on clustering. 相似文献

We contend that generalizability (G) theory allows the design of psychometric approaches to testing English-language learners (ELLs) that are consistent with current thinking in linguistics. We used G theory to estimate the amount of measurement error due to code (language or dialect). Fourth- and fifth-grade ELLs, native speakers of Haitian-Creole from two speech communities, were given the same set of mathematics items in the standard English and standard Haitian-Creole dialects (Sample 1) or in the standard and local dialects of Haitian-Creole (Samples 2 and 3). The largest measurement error observed was produced by the interaction of student, item, and code. Our results indicate that the reliability and dependability of ELL achievement measures is affected by two facts that operate in combination: Each test item poses a unique set of linguistic challenges and each student has a unique set of linguistic strengths and weaknesses. This sensitivity to language appears to take place at the level of dialect. Also, students from different speech communities within the same broad linguistic group may differ considerably in the number of items needed to obtain dependable measures of their academic achievement. Whether students are tested in English or in their first language, dialect variation needs to be considered if language as a source of measurement error is to be effectively addressed. 相似文献

In this paper an explicit numerical procedure is proposed to determine the non-fragility of parameters of controllers used to stabilize a class of time delay systems. The proposed procedure finds the largest possible circle inscribed in a stability subregion delimited by a simple closed curve in the plane of the controller parameters. The center of this circle is declared to be the controller’s least fragile parameters. The obtained theoretical results are applied and compared with some of the most relevant examples found in the literature. This illustrates that the proposed procedure improves previous results found in the literature so far. 相似文献
