The article presents the implementation and findings of a successful collaborative effort with the Oklahoma State Regents for Higher Education (OSRHE), Tulsa Community College (TCC), and two local public school districts, Tulsa Public Schools (TPS) and Union Public Schools (UPS). Known as EXCELerate, it's a five-semester dual enrollment pilot program that received state policy exceptions for juniors and seniors to enroll in dual enrollment courses and supportive resources from the participating agencies. Whereas the traditional dual enrollment student is White and college-going, the program's intent was to increase the number of high school students who may be first-generation, lower-socioeconomic, ethnic or non-ethnic. The article identifies three major barriers to successful dual enrollment and completion: state policy, financial issues, and transportation. It also examines how these barriers were eliminated through a collaborative effort. The results demonstrate that over 87% of the juniors and seniors persisted over the semesters, and enrollment tripled among African American and Latino students. The article is constructed to benefit further research and practical application for urban and rural community colleges. 相似文献

This paper presents conditions to assure the exponential stability in probability for autonomous switching linear systems. The switching signal acting on the autonomous system produces intervals that follow independent, identically distributed stochastic processes—the stability then follows by verifying simple-to-check linear matrix inequalities. 相似文献

The educator's point of view stresses the development potential of education, together with respect for human rights. It is seen that nations need to make clear policy statements in this respect, and the consequent planning and curricular issues, together with some relevant strategies, are indicated.
Zusammenfassung Im Standpunkt des Pädagogen wird gemeinsam mit der Anerkennung der Menschenrechte das Entwicklungspotential der Bildung betont. Nach Meinung des Autors müssen Nationen in diesem Zusammenhang klare politische Aussagen treffen, und der Artikel befaßt sich mit der entsprechenden Planung sowie Themen zum Curriculum und einigen relevanten Strategien.
Résumé Le point de vue de l'éducateur souligne le potentiel de développement offert par l'éducation, ainsi que le respect des droits humains. Il s'avère que chaque nation doit énoncer clairement sa politique à cet égard; l'auteur indique les questions de planification et de curriculum qui en découlent, ainsi que quelques stratégies pertinentes.相似文献

乒乓球是使用单侧上肢的一项运动,其特征是要进行重复多次高速且具爆发力的动作,无氧乳酸酵解代谢能力占有重要作用.研究对象与方法男女高水平乒乓球运动员(n=31).采用Takei5101握力计测量单侧上肢有力型和非单侧上肢有力型运动员的上肢最大等长收缩力.18名男运动员(平均年龄23.5±5.4岁)和13名女运动员(平均年龄21.3±3.3岁)均为西班牙乒乓球协会的国家联盟成员.采用SPSS v12.0 for windows和Excel v10.2软件包进行数据统计分析.研究结果发现无论男女运动员单侧上肢有力型的最大等长收缩力均高于非单侧上肢有力型,而左势手女运动员与右势手女运动员相比、右势手男运动员与左势手男运动员相比,单侧上肢有力型的最大等长收缩力均高于非单侧上肢有力型.研究还发现进攻型运动员与防守型运动员相比,单侧上肢有力型的最大等长收缩力高于非单侧上肢有力型.分析与讨论无论男女,单侧上肢有力型运动员手握力高于非单侧上肢有力型运动员.男性运动员比女性运动员的等长收缩力高,一个可以解释的事实是男性有更高的睾酮水平.肌肉力量不平衡可能发展成为脊柱侧弯姿态,这应该通过适当的力量和柔韧性训练来避免,以防止将来的运动损伤和运动成绩的下降. 相似文献

The paper presents results for the second moment stability of continuous-time Markov jump systems with quadratic terms, aiming for engineering applications. Quadratic terms stem from physical constraints in applications, as in electronic circuits based on resistor (R), inductor (L), and capacitor (C). In the paper, an RLC circuit supplied a load driven by jumps produced by a Markov chain—the RLC circuit used sensors that measured the quadratic of electrical currents and voltages. Our result was then used to design a stabilizing controller for the RLC circuit with measurements based on that quadratic terms. The experimental data confirm the usefulness of our approach. 相似文献

In this study, we analyzed the relationship between running economy (RE) and biomechanical parameters in a group running at the same relative intensity and same absolute velocity. Sixteen homogeneous male long-distance runners performed a test to determine RE at 4.4 m.s-1, corresponding to 11.1% below velocity at the ventilatory threshold. We found significant correlations between RE and biomechanical variables (vertical oscillation of the center of mass, stride frequency, stride length, balance time, relative stride length, range of elbow motion, internal knee, ankle angles at foot strike, and electromyographic activity of the semitendinosus and rectus femoris muscles). In conclusion, changes in running technique can influence RE and lead to improved running performance. 相似文献
