关于山谷冰川冰-岩界面地貌过程与冰川动力耦合模式——以中天山冰川为例

对冰川侵蚀形态的观测与分析得知：（１）冰川槽谷中冰川擦痕的大小和密度在中心较大，鲸背岩出现在冰川槽谷的中部，羊背石发育在槽谷两侧。因此，可以将槽谷分为强烈磨蚀的中部和弱磨蚀而强拔蚀的两侧。（２）冰坎的纵剖面上，迎冰面可见鲸背岩、羊背石以及倾角２０°的剪切裂隙；背冰面以拔蚀为主，见倾角４０°的张性裂隙。沿冰川槽谷纵向，剪切裂隙出现在压缩部位，张裂隙出现在伸张部位。它反映出冷底冰川的动力特性与冰床基岩的受力机制的一致性。     

Territorial justice in unified Germany: Financial equalization, the Länder and the Federal Constitutional Court

Geographers have traditionally been interested in the issue of territorial justice conceived in terms of distributional equality. The German constitution incorporates a concept of financial equalization with the objective of creating equivalent living conditions throughout the federal territory. This primarily involves the redistribution of finance, the regulation of which has been a continual source of conflict. The paper looks at the role of the Federal Constitutional Court in mediating such conflict. The Court is the ‘supreme guardian of the constitution’ and a highly influential policy-making institution within the German political system. Commentators have described a process of the judicialization of politics, with an increasing number of important political decisions being taken by the Court, rather than in Parliament. The decisions of the Court within the sphere of financial equalization are examined in this light. Further, the particular relevance of a geographical perspective in this regard is highlighted.     

Investigating Travel Behavior of Nondriving Blind and Vision Impaired People: The Role of Public Transit

Our purpose is to explore the travel behavior of blind or vision impaired people, focusing in particular on travel by bus. We differentiate the sample depending on the availability of a household car. We examine perceptions of and attitudes toward existing transit and various transit characteristics, highlighting features that seem to be frustrating or difficult. Finally, we have travelers evaluate the potential usefulness of various assistive devices, including electronic information that gives navigational assistance.

A Platform for Visualizing and Experimenting with Measures of Semantic Similarity in Ontologies and Concept Maps

This article describes research in the ongoing search for better semantic similarity tools: such methods are important when attempting to reconcile or integrate knowledge, or knowledge‐related resources such as ontologies and database schemas. We describe an extensible, open platform for experimenting with different measures of similarity for ontologies and concept maps. The platform is based around three different types of similarity, that we ground in cognitive principles and provide a taxonomy and structure by which new similarity methods can be integrated and used. The platform supports a variety of specific similarity methods, to which researchers can add others of their own. It also provides flexible ways to combine the results from multiple methods, and some graphic tools for visualizing and communicating multi‐part similarity scores. Details of the system, which forms part of the ConceptVista open codebase, are described, along with associated details of the interfaces by which users can add new methods, choose which methods are used and select how multiple similarity scores are aggregated. We offer this as a community resource, since many similarity methods have been proposed but there is still much confusion about which one(s) might work well for different geographical problems; hence a test environment that all can access and extend would seem to be of practical use. We also provide some examples of the platform in use.
