This study contributes to the ongoing debate about bilingual advantage and examines whether bilingual immigrant youths fare better, as well as, or worse academically than the matching group of monolinguals. Using data from Spain, where close to half of immigrants speak Spanish as their native language, we found no evidence of costs of bilingualism: bilingual youths did benefit from their linguistic skills. Their advantage, however, manifested itself not uniformly across discrete outcomes, but in a direct trajectory toward higher educational attainment. Bilingualism neutralized the possible negative effect of ethnic origins and extended the positive effect of high parental ambition. Implications for theory and practice are discussed. 相似文献

Based on data from the Survey on Social Conditions in the Canary Islands of the Instituto Canario de Estadística, this study analyzes poverty in Canary households by island of residence, age, employment and the educational level of the main provider. In addition to accepted objective measures, we also estimate poverty using subjective methods, in which the poverty line is defined or obtained by the opinion of household members of their own level of poverty. 相似文献

We examine the institutions that comprise the U.S. health system and their relationship to a surging immigrant population. The clash between the system and this human flow originates in the large number of immigrants who are unauthorized, poor, and uninsured and, hence, unable to access a system largely based on ability to pay. Basic concepts from sociological theory are brought to bear on the analysis of this clash and its consequences. Data from a recently completed study of health institutions in three areas of the United States are used as an empirical basis to illustrate various aspects of this complex relation. Implications of our results for theory and future health policy are discussed. 相似文献

AbstractThis paper aims at examining the trends, challenges and theoretical gaps in the implementation of Healthcare 4.0 (H4.0) based on a scoping review of the literature. For that, we searched journal articles in four widely known databases and screened the retrieved articles to obtain a publications’ portfolio. Our findings indicate that, despite the recency of the subject, research in H4.0 has been conducted in an interdisciplinary way with a diversified set of applications and functionalities. In terms of its implementation, H4.0 has been more commonly found in hospitals’ information flows, especially the ones related to healthcare treatments. The identified implementation trends, however, neglect a more holistic approach for H4.0, which originated three main research directions for this topic. Although identified as a trending topic in the area of healthcare operations management, literature on H4.0 may be viewed as randomly conceived, lacking academic alignment and practical orientation based on a grounded theory, which we aim at providing with the present study. 相似文献

Many recent findings have altered our vision of chromatin and its role in the regulation of cellular functions. Our perspective concerning chromatin has changed to a much more complex, but also more dynamic, view of chromatin as an entity that is intimately involved in the regulation of a variety of cellular functions. In this review, we describe the various types of proteins that alter the structure and, therefore, the function of chromatin and discuss the possible role of chromatin in cell aging. The elucidation of the mechanisms that link chromatin to aging will be one of the most exciting and striking advancements in the coming years 相似文献

Abstract Criticisms of the field of collective behavior can be categorized as either methodological, ideological, or conceptual-theoretical. For methodological problems we examine the views that research on collective behavior is hampered because collective behavior is unpredictable, transitory, fluid, diffuse, complex, and uncontrolled. For ideological problems we look at the claims that the unsatisfactory state of the field of collective behavior is the result of its controversial material and lack of objectivity, defense of the status quo, trivialization of politics, and attributions of social pathology. For methodological and ideological criticisms, we conclude they are generally invalid or incorrect. A better strategy for improving collective behavior theory and research and advancing it closer to mainstream sociology is to focus on the conceptual-theoretical criticisms, for this tactic would have a greater pay off for sociology generally and collective behavior specifically. 相似文献

The purpose of this article is to examine a surge in the sciences surrounding the use of the concept of sustainable development. Data come from the annual frequencies of publications in various disciplines that use the concept of sustainable development as well as from a content analysis of documents. The article concludes that the surge was characterized by the use by scientists of established concepts in a new way, a form of cultural emergence; a prevailing locus of interaction revolving around a professional ideology; the prevalence of the emotions of fear and hope of deliverance from the threat; and an international arena of discourse occurring over a period of years and bounded by class-professional identities. The article demonstrates that a newer understanding of fads as collective surges in the sociology specialty area of collective behavior helps describe the use in the sciences of the concept of sustainable development during the late 1980s and 1990s. The surge is relatively short-lived, coterminous with the use of different meanings and practices of sustainable development. It cannot be understood as a superficial, odd, inconsequential, or frivolous event. Rather, it had important, lasting consequences in a number of areas, from economic and social development to professions. 相似文献

This study combines structural factors of intergroup relations with personal assimilation factors to examine Asian American intermarriage in California, We conduct a multilevel logistic regression analysis of outmarriage among Chinese, Filipinos, and Japanese in 14 California metropolitan statistical areas with high con centrations of Asian Americans by using the 1980 Census Public-Use Microdata Sample. The results show that Asian intermarriage is affected by both assimilation and structural determinants. Some theoretically unexpected findings are discussed that hint at alternative interpretations. 相似文献

In recent years, southern Florida has experienced rapid new inflows of immigrants from Central America and the Caribbean. Since the arrival in 1980 of Mariel (Cuban) and Haitian immigrants to this area, a great deal of speculation has emerged as to the adaptation of these two groups to south Florida and the impact which their presence has wielded on the social and economic arenas of that region. In this paper, we present selected background characteristics of representative samples of both groups and discuss our empirical findings with regard to the labor market experiences, social networks, and educational experiences of the immigrants included in our sample. While the two groups minimally differ from earlier cohorts of their compatriots entering south Florida, their experiences since arriving in Florida have been quite different. Both the Cuban and Haitian immigrants arriving in 1980 demonstrate higher levels of unemployment than their counterparts who arrived earlier; however, the existence of the Cuban economic enclave in Miami did facilitate the entry of a greater number of Cubans than Haitians into the formal labor market. Initial evidence indicates that significant numbers of individuals from both groups participate in the informal labor market, often receiving less than the minimum wage.This study was conducted with the support of the Sociology Program, National Science Foundation (Grant #SES-8215567). 相似文献
