Developing the next generation of engaged youth: Inspire Aspire – Global Citizens in the Making

School-based character education (CE) programs provide an opportunity to increase the moral fortitude of adolescents. This study is a preliminary evaluation of Inspire Aspire, a CE program that was implemented with 13- to 14-year-olds in Scotland. A relational developmental systems meta-theoretical approach and person-centered analyses were employed to understand whether teacher implementation variability is associated with student outcomes. The study aimed to: assess variation in program implementation across teachers; assess student poster quality, which served as a youth outcome measure; and, assess the relationship between variations in program implementation and poster quality. Teachers who fully integrated Inspire Aspire with the broader curriculum (as opposed to using it as a standalone program) as well as teachers who made more modifications to Inspire Aspire tended to have students with higher quality posters. This finding stands in contrast to the common narrative regarding evidence-based programs that requires teachers to strictly adhere to program guidelines in order to maintain implementation fidelity.     

高效毛细管电泳中移动反应界面法富集奶粉中三聚氰胺的方法研究

运用移动反应界面理论建立奶粉中三聚氰胺的毛细管电泳富集分离体系。与传统的毛细管电泳相比,体系中引入了富集缓冲溶液(富集相)和分离缓冲溶液(分离相)。优化的条件:样品缓冲溶液为50mmol/L甲酸-甲酸钠(pH2.60),富集相为20mmol/L甲酸钠-甲酸pH8.00),分离缓冲溶液为50mmol/L～50mmol/L甲酸-甲酸钠(pH2.60);样品压力进样50mbar×40s,富集相压力进样50mbar×20s,紫外检测波长232nm,电压30kv。该方法比常规电泳灵敏度高近20倍。     

Updating Working Memory and arithmetical attainment in school

Here we wished to determine how the sub-components of Working Memory (Phonological-Loop and Central Executive) influence children's arithmetical development. Specifically, we aimed at distinguishing between Working Memory inhibition and updating processes within the Central Executive, and the domain-specificity (words and numbers) of both subcomponents in a population of children with low attainment in arithmetic and their age matched typically-attaining controls. We show that both groups were similar for phonological loop abilities, while Working Memory updating demonstrated a domain-specific modulation related to the level of children's arithmetical performance. Moreover, inhibition processes interacted with domain-specificity and arithmetical attainment. These results are particularly relevant to the diagnostic assessment of arithmetical ability and should be considered in existing tests of arithmetical development.
