The construction of an ethnic or racial identity is considered an important developmental milestone for youth of color. This review summarizes research on links between ethnic and racial identity (ERI) with psychosocial, academic, and health risk outcomes among ethnic minority adolescents. With notable exceptions, aspects of ERI are generally associated with adaptive outcomes. ERI are generally beneficial for African American adolescents' adjustment across all three domains, whereas the evidence is somewhat mixed for Latino and American Indian youth. There is a dearth of research for academic and health risk outcomes among Asian American and Pacific Islander adolescents. The review concludes with suggestions for future research on ERI among minority youth. 相似文献

One point of intersection in ethnic and racial identity research is the conceptual attention paid to how positively youth feel about their ethnicity or race, or positive ethnic–racial affect. This article reports results of a series of meta‐analyses based on 46 studies of this dimension and psychosocial, academic, and health risk outcomes among ethnic and racial minority youth. The overall pattern of results suggests that positive ethnic–racial affect exhibited small to medium associations (r range = |.11| to |.37|) with depressive symptoms, positive social functioning, self‐esteem, well‐being, internalizing, externalizing, academic achievement, academic attitudes, and health risk outcomes. Implications for theory and research about the role of positive ethnic–racial affect among youth growing up in an increasingly diverse society are discussed. 相似文献

Output reversibility involves dynamical systems where for every initial condition and the corresponding output there exists another initial condition such that the output generated by this initial condition is a time-reversed image of the original output with the time running forward. Through a series of necessary and sufficient conditions, we characterize output reversibility in linear discrete-time dynamical systems in terms of the geometric symmetry of its eigenvalue set with respect to the unit circle in the complex plane. Furthermore, we establish that output reversibility of a linear continuous-time system implies output reversibility of its discretization. In addition, we present a control framework that allows to alter the system dynamics in such a way that a discrete-time system, otherwise not output reversible, can be made output reversible. Finally, we present numerical examples involving a discretization of a Hamiltonian system that exhibits output reversibility and an example of a controlled system that is rendered output reversible. 相似文献

The purpose of this paper is to report on who creates branding within institutions of higher learning, and what impact branding has on core institutional activities such as student recruitment and fundraising, as well as on socio‐psychological factors such as community respect and national prestige. Eighty‐nine tertiary education experts covering three world regions were surveyed in order to gather information to fulfil the paper’s objectives. The nature and extent of involvement of enrolled students, alumni, higher management, external consultants, civic leaders and the business community were investigated to identify the part each plays, if any, in the development of an institutional brand. Findings indicate that institutions have a tendency to brand from the top down rather than from the bottom up. 相似文献

ABSTRACTA multilevel framework was applied to investigate the effects of teacher characteristics, school environment, and district level HRM practices on teacher commitment. Drawing on the results from a public school teacher survey conducted in the Emirate of Abu Dhabi in 2014, four forms of teacher commitment (commitment to school, to students, to teaching, and to community) were tested, which provided empirical evidence to further the development of teacher commitment as a multi-foci construct. The results of the three-level model revealed differentiating effects of some individual and organisational variables on different forms of teacher commitment and highlighted that nationality, multiple interpersonal support, and collegial relationships were the most consistent and strong variables to predict teacher commitment. This study suggested that the social and interpersonal environment of school played a significant role in influencing teacher commitment. Results were discussed in relation to improving the commitment of teachers in the empirical context of Abu Dhabi public schools. 相似文献

Ankylosing spondylitis is a chronic inflammatory disease that has been linked to the human leukocyte antigen class I allele HLA-B27. More than 90 % of patients with ankylosing spondylitis possess the HLA-B27 allele, but only 1 % of people with HLA-B27 develop the disease. Ankylosing spondylitis predominately affects young males. The present study was planned to find out the involvement of HLA-B27 specific allele in relation to age and sex in symptomatic suspected patients of ankylosing spondylitis using conventional PCR technology. Forty symptomatic patients of ankylosing spondylitis were included in the present study. SSP–PCR technique was used to detect the HLA-B27 specific allele. This study showed (out of 40 symptomatic suspected cases of ankylosing spondylitis only 12 patients were detected positive with HLA-B27 allele, while remaining 28 were negative) that the positivity rate for ankylosing spondylitis with HLA-B27 allele is low. Furthermore, it was observed that the males above 50 years are more prone to develop AS with HLA-B27 specific allele. It could be concluded that the conventional PCR technology is a rapid, sensitive, and confirmatory method for the diagnosis of ankylosing spondylitis. 相似文献
