划艇运动力学参数检测与分析

研制了一种集划桨力、划桨过程中桨的偏转角度、艇的俯仰角度和倾覆角度、艇速等多个运动力学参数为一体的新型划艇测试评价系统，实现了对这些参数的同步采集。系统通过传感器（力传感器、角度传感器和速度传感器）将采集到的数据无线传输至计算机，利用自行开发研制的软件系统，教练员可以实时地掌握运动员划船过程中的运动状态。整个系统的重量比较轻，并且数据的主要传输采用无线形式，既保证了教练员实时的了解以往单凭眼睛观测和经验判断而很难得到的一些划桨技术细节信息，同时不会对运动员的正常划船技术动作的产生过多的干扰。

Cauchy核中多复变微分方程自回归线性解初值问题

研究Cauchy核中多复变微分方程自回归线性解初值问题,为物理控制和生物医学演化等数学模型的构建提供数学基础。特别在高温冷却下的温度场有限元分析控制中具有重要的控制应用价值,采用非线性微分方程解分析的方法,通过对方程的多个逼近特征解进行分析,提取出所有解的特征,从而求解稳定解,此方法在多解相关性强的情况下具有较好的效果。在两个状态时滞向量的Cauchy核中求解多复变微分方程泛函,得到自回归线性解初值的最小正特征带状的连接权,根据Cauchy核中多复变微分方程泛函,得到Cauchy核最优解和Cauchy核最优边界,通过证明得到Cauchy核中多复变微分方程的自回归线性初值是连续收敛和渐进稳定的,且在闭环控制性能曲面上至少有一个稳定解。分析结果有利于提高高温冷却下的温度场有限元分析控制性能。     

对安徽高等教育强省建设的若干思考

高等教育强省的内涵具有"名词"、"动词"、"动词+名词匹配"三重意义的理解,内涵意蕴不同,则高等教育强省的参照系也是多维的。自2010年安徽省正式推进高等教育强省建设方略、实施"双百"发展方针以来,普通高校数、在校普通本专科生数等指标名列前十强,毛入学率已超全国均值,初步成效明显。今后,重任在肩的安徽高等教育强省建设至少应在以下三大领域发力:顶层设计——进一步旗帜鲜明、大张旗鼓地彰显省域应用性高等教育体系;长远规划——以高等教育强省建设为龙头,引领教育现代化建设目标的基本实现;近期行动——以地方高水平大学分类推进为突破口,强力推进高教强省建设。     

中能重离子碰撞中末态核碎片的各向异性分布

在多源理想气体模型的框架内,用解析和蒙特卡洛两种方法计算分析了中能重离子碰撞中末态核碎片的方位角分布和椭圆流对横动量的依赖关系,并由此分析了末态核碎片的各向异性分布特征。对计算结果与同位旋依赖的的量子分子动力学(ISQMD)模型的计算结果进行了比较,发现二者基本符合。

Professionalisation policies in the ECEC field: trends and tensions in the Italian context

In recent times, a growing consensus has emerged, among researchers and policy-makers, that a well-educated, competent and adequately supported workforce is crucial for the quality of early childhood education and care (ECEC). Despite governmental initiatives aimed to enhance the professional preparation and continuing development of early years practitioners being high on the political agenda of many EU member states, very few studies are analysing professionalisation policy developments and their implications within the national contexts of ECEC. Against this background, the article describes the key features of ECEC policies in Italy and their current trends by focussing specifically on the professionalisation of early childhood practitioners working across 0–3 and 3–6 services. Drawing on the data collected from documentary sources and interviews with key informants, this paper will critically review policy discourses as well as recurring themes and tensions arising from the academic and political debate. The findings from our analysis highlight that the increasing discontinuity characterising professionalisation initiatives across the 0–3 and 3–6 sector might lead to widening the gap among professionals working in such services. The risks that are associated with this trend are, on the one side, to devalue the educational role of 0–3 services and, on the other, to produce the schoolification of educational practices in 3–6 services. In addition, our analysis identified inconsistencies between initial and continuing professional development policies, which are progressively creating a dichotomy between initial and in-service training. The consequences of this process might produce, on the long term, the fragmentation of the ECEC system across public and private not-for-profit provision with the subsequent risk of impoverishing the local culture of childhood on which the Italian ECEC system has traditionally built its strength.     

Voice over distance: a case of podcasting for learning in online teacher education

This paper reports on a case study of an online pre-service teacher education course in a New Zealand university aimed at exploring the potential of student-generated podcasts as a form of interactive formative assessment at a distance. The study was part of a wider two-year funded project with the overall goal of documenting, developing, and disseminating effective and innovative e-learning practice. Findings from lecturer and tutor interviews, student focus group (FG) discussion, and course evaluations indicate that the podcasting task provided opportunities for the course lecturer, tutors, and students to learn and share ideas with one another. The experience empowered students to develop the skills and confidence to initiate more independent inquiry into technologies to support their pedagogical purposes. The study contributes to a better understanding of the skills, dispositions, and knowledge needed to prepare teacher candidates for teaching-learning contexts where information and communication technologies are increasingly pivotal.
