A growing body of research suggests educators need to focus on cultivating social and emotional competencies that youth will need to thrive in the new knowledge economy (Durlak, Weissberg, Dymnicki, Taylor, &; Schellinger, 2011). For marginalized urban youth, in particular, few have derived programs and interventions to assist with these competencies. This study illuminates the perspectives of 9 African American youth at risk for academic failure taking part in the Fulfill the Dream (FTD) program. FTD is a social and emotional learning curriculum emphasizing social justice and critical consciousness through the utilization of hip-hop culture. Information regarding the nature of the collaboration of this research project and recommendations for education professionals working with marginalized youth are discussed. 相似文献

The purpose of this study was to identify the various ways that instructors communicatively fulfill college students’ basic psychological needs (i.e. autonomy, competence, relatedness) in the classroom. Participants were 119 undergraduate students who completed open-ended, self-report questionnaires. Analyses of the coded data revealed that a variety of instructor communication behaviors and practices previously identified in the effective teaching literature fulfill students’ needs for autonomy, competence, and relatedness. According to Deci and Ryan’s (1985) self-determination theory, the fulfillment of these needs intrinsically motivates students to learn, develops their cognitive capacities, and equips them for short-term and long-term success. 相似文献

We report an interesting buffer electric relaxation time tuning technique, coupled with a glutaraldehyde cross-linking cell fixation reaction, which allows for sensitive dielectrophoretic analysis and discrimination of bovine red blood cell (bRBC) starvation age. The buffer composition is selected such that two easily accessible dielectrophoretic crossover frequencies (cof) exist. Low concentration glutaraldehyde fixation was observed to produce a threefold decrease in the higher cof with a comparable increase in the lower cof also witnessed. More importantly, increased glutaraldehyde fixation concentration significantly increased the higher cof by a factor found to be sensitive to the bRBC starvation age. 相似文献

An increase in salivary leukocytes may contribute to the exercise-induced increase in salivary antimicrobial proteins (AMPs). However, exercise-induced changes in salivary leukocytes have not been studied. The purpose of the study was to describe salivary leukocyte changes with exercise. Participants (n = 11, 20.3 ± 0.8 years, 57.2 ± 7.6 ml kg?1 min?1 peak oxygen uptake ((VO) ?2peak), 11.1 ± 3.9% body fat) ran for 45 min at 75% of VO2peak. Stimulated saliva (12 mL) was collected pre- and immediately post exercise. Saliva was filtered through a 30 µm filter before analysis of leukocytes (CD45+), granulocytes (CD45+CD15+), monocytes (CD45+CD14+), T-cells (CD45+CD3+), and B-cells (CD45+CD20+) using flow cytometry. Saliva was analysed for Lysozyme (Lys) using ELISA. Exercise did not alter any leukocyte subset. The major constituent of leukocytes pre-exercise were granulocytes (57.9 ± 30.3% compared with monocytes: 5.1 ± 2.7%, T-cells: 17.1 ± 8.9%, B-cells: 12.1 ± 10.2%) (P < 0.05). In a subset of n = 6, Lys secretion rate increased after exercise (pre: 5,170 ± 5,215 ng/min; post: 7,639 ± 4,140 ng/min) (P < 0.05). Exercise does not result in increased granulocytes, but does increase Lys. Further, these data suggest that an increase in salivary leukocytes is not needed to increase Lys. 相似文献

This is an interpretivist qualitative study that explores the contexts and dynamics of friendships between three groups of young adults; each group includes an individual with autism or severe disability and nondisabled high school students. The most prominent finding identified in the data was that educators affected opportunities for social interactions between students with and without autism or severe disability. Educator influence on social participation included factors that decreased interactions, such as missed opportunities for social interactions and social consequences of academic supports. Educator influence also included factors that increased interactions, specifically four strategies to increase social interactions and facilitate possible friendships or maintain existing friendships between students with and without autism or severe disability. 相似文献

This investigation explores the influence of perceptions of socialization tactics' use and communication relationships on employees at the initiation of and 4 months into an organizational restructuring. Results of this longitudinal investigation reveal that employees (N = 72) report considerable changes in perceptions of organizational socialization/resocialization efforts. Results also indicate that both perceptions of socialization tactics' use and communication relationships contribute to decreased role ambiguity and role conflict and increased commitment at the initiation of the restructuring and four months later. However, the influence of these factors on the dependent variables changes over time. These findings are discussed in relation to recent research on organizational entry and change, and suggestions are made for future research. 相似文献
