Research on multiracial individuals is often cross-sectional, obscuring the fluid nature of multiracial self-categorization across time. Pathways of racial self-identification are developed from a nationally representative sample of adolescents aged 14-18, measured again 5 years later. A significant proportion of multiracial adolescents change racial self-identification across time. Youth who ever report being multiracial are 4 times as likely to switch self-identification as to report consistent multiracial identities. Across this time, more multiracial adolescents either add a racial category (diversify) or subtract one (consolidate) than maintain consistent multiracial self-categorization. Exploratory multinomial analyses show few differences between these pathways on select psychological and social characteristics. Results lend quantitative support to qualitative studies indicating the fluidity of racial self-categorization.  相似文献

Student persistence and completion are paramount in higher education, and institutions are employing targeted programs and initiatives to address these concerns. The academic library can play an especially important role in these efforts, given its unique interdisciplinary mission and its integrated instructional programs. With a foundation in both higher education and library and information science literatures, this article describes how one academic library engaged in cross-campus programs, partnerships, and initiatives to contribute to student success efforts. Other libraries may find these examples useful as they consider how to frame their work in the context of their institutions’ student persistence efforts.  相似文献

There are many ethical responsibilities in preparing and publishing a scientific paper. The various responsibilities of authors, referees, editors and publishers are considered. While editors and publishers have a responsibility to seek to identify unethical or fraudulent papers, this is not always possible and primary responsibility for the accuracy of papers must lie with the authors. Editors however have a greater responsibility to try to ensure ethical behaviour in the refereeing process and to draw referees’ attention to the privileged nature of the paper under review. The requirements for the ethical handling of papers by the editors and publishers are also discussed, as are recent developments in public interest in the question of ethics in publishing papers.  相似文献

Imagine a time when students will carry one small card that they can use to access reference materials, buy football tickets, and receive financial aid through an ATM. Fantasy? No, says Glen McCandless, this reality is just around the corner.  相似文献
