This article examines the frontier between the Seljuk Sultanate of Rūm and its Byzantine neighbours in the thirteenth century, concentrating on the place of these frontier districts within the Seljuk state. Scholarship on the frontier, influenced by the ideas of Paul Wittek, has seen it as something of a “no man's land”, politically, economically, culturally and religiously distinct from the urban heartland of the Seljuk sultanate in central Anatolia, dominated by the nomadic Turks, the Turkmen, who operated largely beyond sultanic control. It is often thought that the Seljuk and Greek sides of the border shared more in common with each other than they did with the states of which they formed a part. In contrast, this article argues that in fact the western frontier regions were closely integrated into the Seljuk sultanate. Furthermore, with the Mongol domination of the Seljuk sultanate in the second half of the thirteenth century, the Seljuk and Mongol elites became increasingly involved in this frontier region, where some of the leading figures of the sultanate had estates and endowments. 相似文献

The educational experiences of Southeast Asian Americans, particularly Cambodian Americans, Hmong Americans, Laotian Americans, and Vietnamese Americans, are characterized by numerous challenges, which can be attributed to their migration history, socioeconomic status, and English proficiency. By the end of 11th grade, a high percentage of Southeast Asian American students are not college ready. The educational challenges of Southeast Asian Americans have been overshadowed by the model minority stereotype. Educational policies targeting issues affecting the education of Southeast Asian Americans and teacher preparations that focus on getting Southeast Asian American students to be college ready could help change the educational story of this population. 相似文献

A critically transformative education continues to be at the center of Tucson Unified School District's (TUSD) equity and academic excellence mission. Through the use of the Social Transformation paradigm and the lesson learned from the implementation of the Critically Compassionate Intellectualism Model, TUSD once again created a cutting edge transformative, cultural, ethnic, multicultural, equity-based curricula that seeks to stimulate the blossoming intellectual capacities of our students. It presents the opportunity to build foundations and structures of collective and individual agency. Along the lines of agency, it promotes what is called barriorganic intellectualism and the nurturing of gardens of intellectualism (jardines del intelectualismo) that provide opportunities for both the academic and personal transformation of our students. 相似文献

Motor performance is an important health resource. Review articles revealed a decline of motor performance of approximately 10?% between 1975 and 2006. In the past most of the data available for such comparisons came from ad hoc studies with non-standardized methods. Within the framework of the ”Motorik-Modul“ (MoMo) study as part of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), it is possible for the first time to directly compare two cohorts in the ages of 4–17 years in a nationally representative database for Germany. The aim of this article is to report changes in motor performance of children and adolescents in the time period 2003–2006 (cohort baseline n = 4528) compared to 2009–2012 (cohort wave 1, n = 2820). Overall, it is clearly shown that the motor performance of children and adolescents in Germany did not decrease within the observational period of 6 years. The comparison of mean values of the baseline cohort compared to those of wave 1 showed that 28 out of 52 mean values of the two cohorts with a high probability did not differ based on 95?% confidence intervals (CI). In 24 out of the 52 mean values positive changes could be noted based on the individual 95?% CI values. There were more positive changes in primary school aged children than in other age groups. Within these positive changes, most effect sizes were small to medium. The results indicate that recent activities aiming at elevating motor performance levels may have started to make an impact and should be expanded, also in secondary schools. The comparative cohort study presented in this article is currently being checked by the ongoing MoMo wave 2 survey of 2014–2017. 相似文献
