定向运动员的认知方式与感受性的相关研究

运用丈献资料、心理实验测量和数理统计等研究方法,对肇庆学院55名不同水平组定向运动员的认知方式及6项心理感受性指标进行比较研究,研究表明：专项训练对定向运动员认知方式的场独立性和操作思维敏捷性的发展有良好的促进作用;学习迁移率与操作思维敏捷性呈非常显著负相关,即操作思维越敏捷,越能产生正迁移;认知方式与学习迁移率、不同水平呈显著正相关,即学习正迁移率越高、水平越高的定向运动员,其认知方式越趋向于场独立型;不同水平与操作思维敏捷性呈显著负相关,即水平越高的定向运动员,其操作思维越敏捷．     

玩中学：定向运动在幼儿园体育游戏中的价值分析与反思

定向运动作为一项综合性较强的体育游戏,不仅可以强健一个人的体魄,更能培养一个人的观察力、坚持性、判断力等学习品质,而这些学习品质的养成不仅对于幼儿未来的学习和生活是至关重要的,也是幼儿园五大领域教育的核心所在。本文以《3-6岁儿童学习与发展指南》为依据,通过对定向运动的介绍,分析定向运动在幼儿园开展的适宜性以及在培养幼儿学习品质中的价值,从而就如何实现其价值提出一些反思。     

The planning of cycle trips in the province of East Flanders

Traditional route planners assist in finding the shortest or fastest route from one place to another. This paper presents a novel approach to path finding in a directed graph, namely a target distance, motivated by the problem that a recreational cyclist deals with when searching a nice route of a certain length. The problem is defined as a variant of the arc orienteering problem (AOP), a new combinatorial optimisation problem in which the score of a route in a directed graph has to be maximised by visiting arcs, while each arc can be visited at most once and the total cost of the route should not exceed a predefined cost. The contribution of this paper is threefold: (1) a mathematical model of the AOP is provided, (2) a metaheuristic method that solves AOP instances to near optimality in 1 s of execution time, is proposed and evaluated, and (3) two real-life applications of the method are presented. An on-line cycle route planning application offers personalised cycle routes based on user preferences, and an SMS service provides cyclists “in the field” with routes on demand.     

中外定向运动精英竞技水平比较研究

为了寻求我国与世界定向运动水平差距的原因所在,探索我国定向运动发展途径,对2004年世界公园定向巡回赛南京、苏州和上海站比赛的中国前5名与世界前5名成绩进行对比。结果表明：中国定向运动水平与世界定向水平之间在技术、体能和比赛经验等方面都存在着较大的差距和不足。其差距主要表现在对定向地图的快速阅读与理解、地图使用与实地判断。以及定向野越连续奔跑与穿越能力。
