One of the most significant obstacles to inquiry and deliberation is citizenship education. There are few mechanisms for the development of citizens’ democratic character within most societies, and greater opportunities need to be made to ensure our democracies are epistemically justifiable. The character and quality of citizens’ interactions are a crucial aspect for any democracy; their engagement (or lack thereof) make a significant difference between a deliberative society and an electoral oligarchy. I contend that through demarchic procedures, citizens are subject to collective learning process in virtue of being part of communal decision-making and in so doing can develop their capacities for deliberation with practice over time. Demarchic bodies (functionally decentralised authorities that have members chosen by random selection) can be utilised as communities of inquiry (learning processes where participants collectively construct a problem). By viewing democracy as both a learning process and a decision-making mechanism, the quality of deliberation and participation can improve over time as well. 相似文献

The Microsoft Xbox One Kinect? (Kinect V2) contains a depth camera that can be used to manually identify anatomical landmark positions in three-dimensions independent of the standard skeletal tracking, and therefore has potential for low-cost, time-efficient three-dimensional movement analysis (3DMA). This study examined inter-session reliability and concurrent validity of the Kinect V2 for the assessment of coronal and sagittal plane kinematics for the trunk, hip and knee during single leg squats (SLS) and drop vertical jumps (DVJ). Thirty young, healthy participants (age = 23 ± 5yrs, male/female = 15/15) performed a SLS and DVJ protocol that was recorded concurrently by the Kinect V2 and 3DMA during two sessions, one week apart. The Kinect V2 demonstrated good to excellent reliability for all SLS and DVJ variables (ICC ≥ 0.73). Concurrent validity ranged from poor to excellent (ICC = 0.02 to 0.98) during the SLS task, although trunk, hip and knee flexion and two-dimensional measures of knee abduction and frontal plane projection angle all demonstrated good to excellent validity (ICC ≥ 0.80). Concurrent validity for the DVJ task was typically worse, with only two variables exceeding ICC = 0.75 (trunk and hip flexion). These findings indicate that the Kinect V2 may have potential for large-scale screening for ACL injury risk, however future prospective research is required. 相似文献

Turnout is a central element of classical ballet which involves sustained external rotation of the lower limbs during dance movements. Lower leg and foot compensation mechanisms which are often used to increase turnout have been attributed to the high incidence of lower limb injury in dancers. Evaluation of dancers’ leg posture is needed to provide insight into the lower limb kinematic strategies used to achieve turnout. The primary purpose of this study was to use 3D kinematic analyses to determine the lower leg and foot compensations that are incorporated by female university dancers to accentuate their turnout. Active and passive external tibiofemoral rotation (TFR) was also measured. A moderate-strong negative relationship was observed between hip external rotation (HER) and foot abduction in the three first position conditions. A moderate negative relationship was found between passive TFR and foot abduction in all first position conditions. Our findings suggest dancers are more likely to pronate, than rotate the knee to compensate for limited HER. Dancers with a limited capacity to pronate may force additional rotation via the knee. Ongoing research would benefit from more in-depth analyses of the foot/ankle complex using a multi-segment foot model. 相似文献

参加有组织的体育运动和休闲活动存在发生严重伤病甚至死亡的内在风险。虽然造成体育运动或体育活动中猝死的原因有很多,但运动医学和循证标准治疗方面的进展已使临床医生得以更有效地预防、发现和治疗可能致死的伤患。随着研究与技术不断发展进步,当前的治疗标准正在不断发展以更好地改善患者的治疗效果。本文提出了10个与运动和体育活动中猝死的主要原因及其治疗手段有关的关键问题,未来开展的研究将提高运动员和休闲运动爱好者参与运动的安全度。当前证据表明,如采取正确的预防策略或最佳治疗方案,绝大多数的死亡案例是可以避免的。 相似文献

It is well documented that clinical supervision in school settings is underutilized. One hypothesis for this situation is the lack of fit between current supervision models that emphasize the supervision of individual counseling and the multiple roles of school counselors within comprehensive school counseling programs (CSCPs). The authors propose the School Counseling Supervision Model (SCSM) as an extension of J. M. Bernard's (1979, 1997) Discrimination Model. The SCSM uses a 3 (focus of supervision) × 3 (supervisor role) × 4 (CSCP domain) matrix. Examples are provided for potential supervision interventions using the SCSM. Implications for training, practice, and research are discussed. 相似文献

The purpose of this study was to explore the role of counselors in providing validation for men of color in community colleges. Through protocol writing, 13 counselors from seven community colleges responded to open-ended questions asking them to reflect and describe strategies they employed when advising and counseling men of color. Thematic analysis using a combination of detailed, selective, and wholistic reading approaches, as described by van Manen (1990), was employed to identify themes reflecting different forms of validation. Findings from this study demonstrate the critical role of community college counselors as validating agents in affirming men of color as being capable of college success, helping them build confidence, affirming them as individuals, and providing opportunities for academic and personal development. Implications for practice are discussed. 相似文献

To identify links among professional development, teacher knowledge, practice, and student achievement, researchers have called for study designs that allow causal inferences and that examine relationships among features of interventions and multiple outcomes. In a randomized experiment implemented in six states with over 270 elementary teachers and 7,000 students, this project compared three related but systematically varied teacher interventions—Teaching Cases, Looking at Student Work, and Metacognitive Analysis—along with no‐treatment controls. The three courses contained identical science content components, but differed in the ways they incorporated analysis of learner thinking and of teaching, making it possible to measure effects of these features on teacher and student outcomes. Interventions were delivered by staff developers trained to lead the teacher courses in their regions. Each course improved teachers' and students' scores on selected‐response science tests well beyond those of controls, and effects were maintained a year later. Student achievement also improved significantly for English language learners in both the study year and follow‐up, and treatment effects did not differ based on sex or race/ethnicity. However, only Teaching Cases and Looking at Student Work courses improved the accuracy and completeness of students' written justifications of test answers in the follow‐up, and only Teaching Cases had sustained effects on teachers' written justifications. Thus, the content component in common across the three courses had powerful effects on teachers' and students' ability to choose correct test answers, but their ability to explain why answers were correct only improved when the professional development incorporated analysis of student conceptual understandings and implications for instruction; metacognitive analysis of teachers' own learning did not improve student justifications either year. Findings suggest investing in professional development that integrates content learning with analysis of student learning and teaching rather than advanced content or teacher metacognition alone. © 2012 Wiley Periodicals, Inc.
