Ethnic Identity Development and Acculturation Preferences Among Minority and Majority Youth: Norms and Contact 下载免费PDF全文

This article tests a longitudinal model of the antecedents and consequences of changes in identification with indigenous (Mapuche) among indigenous and nonindigenous youth in Chilean school contexts over a 6‐month period (633 nonindigenous and 270 Mapuche students, Mages = 12.47 and 12.80 years, respectively). Results revealed that in‐group norms supporting contact and quality of intergroup contact at Time 1 predicted student's changes in Mapuche identification at Time 2, which in turn predicted changes in support for adoption of Chilean culture and maintenance of Mapuche culture at Time 2; some of the relationships between these variables were found to be moderated by age and ethnicity. Conceptual and policy implications are addressed in the Discussion . 相似文献

We study Spanish savings banks from the point of view of their efficiency, transparency in the disclosure of financial information through the net, and the provision of electronic banking services. Performance indicators are developed using data envelopment analysis and the tools of multivariate statistical analysis. The choice of indicators is framed within the theory of intangible assets. An attempt is made rank savings banks according to their level of achievement in each indicator. Savings banks are shown to be classified into four groups according to the level of achievement in the indicators of transparency and e-service. The relationship between efficiency and profitability is also discussed. 相似文献

Signal constellations in the hyperbolic plane are provided as an alternative to traditional signal constellations in the Euclidean plane, since channels may actually exist for which the latter signal constellations are not as suitable as the former. A hyperbolic gaussian probability density function, based solely on geometrical considerations, is derived to determine the performance of the hyperbolic signal constellations. Benefits result from an approach conceived in terms of reduced signal-to-noise ratio, needed to achieve a prescribed error rate and equivalent optimum receiver complexity. 相似文献

Presently, science is an important precondition for the economic development of less-developed countries. This paper discusses the specific roles that science has at initial stages of development, pointing to its contributions for the countries’ absorptive capability. Furthermore, this paper specifies the role of science for initiating a positive interaction with technological development, since initial stages of development and during catching up processes. For less-developed countries, neither the linear model of technology nor an “inverted linear model” would take place: a more interactive approach is necessary for development. Using statistics of patents (USPTO) and scientific papers (ISI) for 120 countries (1974, 1982, 1990, and 1998), this paper analyses some evidences on thresholds levels of scientific production to originate an interactive relationship between science and technology. These data also document that the value of this threshold seems to double from one period to another. Although this paper presents tentative results, some policy implications are discussed: scientific institutional building must be seen as a component of modern industrial policies. 相似文献

For Latina/o undergraduates, ethnic identity is an important construct linked to self‐esteem and educational attainment. Internalized and perceived racism have been hypothesized to hinder ethnic identity development in Latina/o undergraduates. To assess if internalized and perceived racism were inversely related to ethnic identity, the author conducted a hierarchical linear regression with 373 Latina/o undergraduates. There was a significant relationship between internalized racism and ethnic identity. Findings indicate a need to challenge internalized racism in Latina/o undergraduates. 相似文献

Learning theories are rarely considered in the design of conservation education programs in Mexico. However, if students are taught in a way in which they can easily relate, this could improve the educational experience through better attitudes toward the natural environment. The learning preferences of 354 Mexican children at the primary level were evaluated to identify the effect of context (rural or urban) and gender on learning preferences. Statistical differences related to the children's context and gender-associated context were found. The authors discuss different discourses of critical thinking and experiential education, the predominance of traditional education found in rural communities, and how conservation education could enrich these processes. Studying how children learn can provide valuable information for the development of effective conservation education programs, establishing a dialogue about learners' strengths and weaknesses, enhancing their participation, and empowering them to take action. 相似文献
