The effects of visual realism,spatial abilities,and competition on performance in map-based route learning in men

We report on how visual realism might influence map-based route learning performance in a controlled laboratory experiment with 104 male participants in a competitive context. Using animations of a dot moving through routes of interest, we find that participants recall the routes more accurately with abstract road maps than with more realistic satellite maps. We also find that, irrespective of visual realism, participants with higher spatial abilities (high-spatial participants) are more accurate in memorizing map-based routes than participants with lower spatial abilities (low-spatial participants). On the other hand, added visual realism limits high-spatial participants in their route recall speed, while it seems not to influence the recall speed of low-spatial participants. Competition affects participants’ overall confidence positively, but does not affect their route recall performance neither in terms of accuracy nor speed. With this study, we provide further empirical evidence demonstrating that it is important to choose the appropriate map type considering task characteristics and spatial abilities. While satellite maps might be perceived as more fun to use, or visually more attractive than road maps, they also require more cognitive resources for many map-based tasks, which is true even for high-spatial users.     

Surface Geophysical Methods used to Verify the Karst Geological Structure in the Built-up Area: A Case Study of Specific Engineering-Geological Conditions

This article presents a research study of complex limestone karst engineering-geological conditions in the municipality Valaská near Banská Bystrica in Slovakia. The aim of the study is to demonstrate the impossibility of spatial identification of cave spaces using surface geophysical methods due to the specific engineering-geological conditions of a thick surface layer of anthropogenic fill containing highly heterogeneous anthropogenic material. Its maximum thickness is 3 m. Another specificific condition of the study area is its location in the built-up area, due to which the applicability of geophysical methods was limited. The article contains methodological recommendations to be used in analogous geological conditions with karst structures topped with anthropogenic fill, which complicates the identification of cave spaces. The recommended solution herein is the identification of the cave system using underground mapping of the karst and its projection onto the surface for which surface geophysical methods have been combined.

中国户外运动网站信息流对人流生成的导引机制分析--以乐游户外运动俱乐部网站为例

本文以乐游户外运动俱乐部网站为案例,探讨中小型“自我依托”户外运动俱乐部网站信息流对人流生成的导引作用问题,认为这种作用经过网站访问者的信息获取、知识转化、认知与决定的过程而发生,经过网站交流媒介的信息、集聚、交流和组织四种平台而完成。本文也初步确定与信息流对人流生成的导引作用相关的决策影响要素,认为计划、资金、会员以及赞助商和媒体4种要素对俱乐部网站的良好运行能起到决定性作用。通过将网站使用者作为出发点来研究虚拟一现实组织特征,也能发现许多信息社会人文地理学发展的问题。     

我国山地旅游资源特征及可持续开发利用对策探讨

山地旅游资源分为自然旅游资源和人文旅游资源。我国山地旅游资源的特色鲜明,不仅旅游资源丰富多样,开发利用潜力巨大,而且大部分山地既是风景区,叉是自然保护区,是开展各种旅游与科考活动的极佳场所。长期困扰我国山地旅游资源开发的主要问题是资金投入不足、交通不便、基础设施落后、管理混乱。近年来,国家和地方有关部门已加大对山地旅游资源开发规划和管理整顿的力度,促使山地旅游资源开发逐步迈上科学、和谐发展的轨道,其特有的价值和经济效益得到初步体现。文章在分析我国山地旅游资源特征、开发优势的基础上,提出了我国山地旅游资源可持续发展的具体对策。
