The retention question in context-specific teacher education: Do beginning teachers and their program leaders see teachers' future career eye to eye

This paper discusses the challenge of retaining teachers in hard-to-staff schools by examining how it is addressed in three context specific teacher education programs, which prepare teachers to teach in urban public, urban Catholic, and Jewish Day Schools in U.S.A. The findings of this study suggest that counter to teaching force trends teachers from the three programs that we studied expressed high motivation to serve as teachers or leaders in their particular schools and communities. In particular, we found that teachers' career commitments developed around the religious or civic missions promoted by their respective programs. Finally, teachers' career perceptions seem to correlate, though not entirely match, with those of their program leaders.     

新型连续注射水相法合成CdS量子点

基于连续注射进样系统,研究了水溶性CdS量子点的合成方法。结果表明连续注射技术可实现对反应物比例的精确控制,从而快速确定最佳反应物比例,所制得CdS量子点荧光特性较为稳定。激发波长范围为340—360nm,且在480～510nm的宽波长范围有强烈荧光发射。在最佳反应物比例为nc1：nTCA：ns=1．00：1．15：0．90时,最大荧光发射波长为504nm。CdS量子点的荧光显微成像表明其水溶液分散性良好。     

Reflections on soccer,sovereignty and the state of exception

In this paper, I examine soccer, sovereignty and the state of exception. The paper is a pedagogical tool for undergraduate students in order for them to learn about sovereignty and the ‘state of exception’ through soccer, the world’s most popular sport. I begin by examining differing conceptions of sovereignty and the state of exception. I then highlight the fate of soccer under various states of exception. I focus on Pinochet’s Chile, but also provide examples from the Argentinean military junta, Nazi Germany and El-Sisi’s Egypt. I then reflect about soccer, sovereignty, and the state of exception in relation to Fédération Internationale de Football Association. I offer concluding remarks about soccer and states of exception. I argue that states of exception are in theory opportunities for change because they expose the naked aggression of states, but in practice they represent a danger for soccer players, fans and democracy.
