Studies show that supply chain integration (SCI) is important to organizations. This article describes an activity that places students in the middle of an SCI scenario. The highly interactive hands‐on simulation requires only 50 to 60 minutes of classroom time, may be used with 18 to about 36 students, and involves minimal instructor preparation. Through the activity, students learn the basics of SCI and then analyze an SCI event to better appreciate the need for collaboration and information sharing. In courses that address supply chain management, instructors can use the activity early in the semester to introduce students to the complexities of supply chain networks. Alternatively, instructors may use the simulation later to provoke a more nuanced discussion.  相似文献

Many feminist philosophers of education have argued that the teacher's pleasure plays an important role in the classroom. However, accessing such pleasure is often easier said than done. Given our current academic climate, how might teachers develop pedagogical practices that cultivate these delights? This article investigates the (rather surprising) response to this question offered in Augustine's De catechizandis rudibus. Despite his reputation as a pleasure‐hater, Augustine spends the majority of his text defending the delights of teaching. In particular, Augustine argues that if teachers wish to find pleasure in teaching, they would do well to study the pleasures of mothers. To this end, I analyse the nature of Augustine's maternal appeal. What insight does Augustine find in the experiences of mothers? In what way does he hope his colleagues will allow these experiences to shape their pedagogies? I conclude by exploring the benefits and the risks of Augustine's claim for those who teach in the contemporary feminist classroom. Augustine's defence of pedagogical pleasure suggests that he shares a common interest with feminist philosophers. But, the social/political limits of his account highlight the value of submitting such pleasures to the terms of feminist critique.  相似文献

Abstract

Four sprint starting positions—the bunch, medium, elongated, and hyperextended—were compared on mean elapsed times at distances of 10 and 30 yd. Averages of three starts for each of 30 inexperienced college undergraduate males on each type of start were derived from electronically-controlled measures, the times for both distances being recorded from the same start. Statistical analyses indicated significantly lower elapsed times with the hyperextended starting position.  相似文献

Aging and its effects on a person's quality of life are a growing health concern and burden for many Americans. Recently, studies have shown that adopting certain healthy behaviors may help maintain and or prevent age-related health issues such as cognitive decline. However, many people are unaware of these newfound facts. Furthermore, there is insufficient research evidence to understand how older adults view brain health and the differences between diverse groups of older adults. This study examines brain health knowledge and behaviors among Caucasian and African-American community-dwelling older adults in North Carolina. Findings were significant for level of education and total brain health knowledge scores, though there were no significant differences between races. In addition, there was a significant association between total number of health conditions and total brain health knowledge scores that warrants further study.  相似文献
