Recent studies on pottery and related materials have shown there to be cases where the degree of supralinearity is dependent on the previous radiation history of the sample. Results are presented of two investigations of this variation with pre-dose: one using pottery, the other using fired feldspars. For these samples no simple form for the variation can be inferred. 相似文献

The basic elements of geographic education in American universities are considered, including the number of geography departments, number of students specializing in geography, and the number of teachers. The teacher-to-student ratio, the nature of geographic specialization, and some features of the educational process are outlined, using the Department of Geography of the University of Illinois at Urbana/Champaign as an example. Some new trends in the development of American geography are brought out, such as the growing interest in physical geography and in research on domestic matters, and a greater emphasis on applied geography.

The paper has presented an approach to cellular network pattern analysis which is novel in several respects. First, the approach emphasizes the consideration of the complete geometric structure of the pattern rather than the examination of summary statistics for individual variables or correlations between pairs or other combinations of variables. By comparing empirical structures with model-generated ones it is suggested that the approach offers a way of evaluating the relative impact of the three major forces thought to be responsible for the geometric structure of a network, i.e., the generating process, the phenomena expressed in the network, and the function of the network. It was demonstrated how different processes can lead to diverse geometric structures. Examination of two empirical networks composed of bus service centre hinterlands suggested that the generating process was the dominant determinant of physical structure in this particular instance. However, more research on other cellular networks consisting of different phenomena, and on different generative processes, must be undertaken before any firm conclusions can be reached. The approach taken here would seem to offer one way of undertaking such research. 相似文献

宁夏赴阿拉伯国家出境商务旅游影响因素及机理研究 总被引:1,自引:0,他引:1
以宁夏赴阿拉伯国家商务游客为研究对象,通过问卷调查获取相关数据信息,采用主成分分析方法和地理探测器分析方法,对商务旅游的影响因素及机理进行了研究,结果发现:①宁夏赴阿出境商务游客呈现出高学历、高收入、高回访率的“三高”特征。②按影响因子解释力由大到小依次为:增加贸易量 > 收集产品信息 > 广告效应 > 商贸信息传播 > 文化交流 > 旅游购物。商贸活动是赴阿商务旅游的启动因素,其中“增加贸易量”是其最主要的影响因素,文化交流因子影响力较弱,但在赴阿商务旅游与贸易活动中作用独特。③各影响因素之间的互动影响,形成了赴阿商务旅游影响机理:“商贸目的激发商务旅游-形成商贸订单和合作关系-提升贸易额-推动信息传播-产生广告效应-促进文化交流-构建了人际关系-产生了新的商机-引发更大规模的旅游和贸易活动”。 相似文献

The “localities debate,” stimulated by the Economic and Social Research Council's “Changing Urban and Regional Systems” initiative, was conducted in the pages of Antipode and Society and Space at a length that showed scant regard for emerging environmental sensitivities. Much of it involved politically contentious claims and increasingly exhausted theory; it resolved very little and in that sense was little more than a storm in a pretty familiar pudding basin. A later flirtation with postmodernism simply pushed aside questions of explanation while raising the political stakes as celebration of the differences between places became the order of the day. Nonetheless, important issues emerge from or relate to that debate, and we draw on our experiences to comment on three of them: (i) agents, structures, the production of space and the material bases of place: some issues of theory; (ii) the production of places, people's attachment to place, and place-based political strategies: some issues of practice; (iii) localities, postmodernism and the difference that place makes: is the regressive turn to postmodernism as approach avoidable? 相似文献

身体视角下的旅游体验——基于徒步游记与访谈的扎根理论分析 总被引:1,自引:0,他引:1
身体理论的发展为旅游体验本质的探究提供了新的可能,国内外的研究开始关注人的某些感官体验,但作为一个整体的身体还极少得到审视。在梳理相关文献的基础上,采用身体地理学视角,对收集的徒步旅行游记和访谈进行扎根理论分析,提炼出24个范畴、7个主范畴和1个核心范畴,据此建立旅游体验本质模型。结果表明,徒步旅游体验本质上是一种具身化生成实践,即旅游者通过具体身体的参与,与旅游情境深度融合,寻求个体完善与成长的对象性活动。具体包括身体意识的唤醒、身心的浸入、与他人和自然的共在以及个体的生成等四种体验类型。这些体验主要通过旅游者由身体痛苦到精神快乐的逆向选择、具有仪式象征意义的行为表演和面向自我的反思性观照三种典型路径达到。在此过程中,作为整体的身体解除了规训和压制,展现出生动鲜活的样貌,迈向持续的生成之域。 相似文献

This response to Carola Dietze's critique of Provincializing Europe takes up for examination three key expressions or ideas on which the original argument of the book was founded: hyperreal Europe, historicism, and political modernity. I appreciate the spirit of Dietze's engagement with the book, but I show that her critique is based on a degree of misapprehension of these three central ideas. While clarifying the details and the degree of my disagreement with Dietze, I provide my own critique of Dietze's proposal of “equal histories” by arguing that Dietze has not named or explained the unit with respect to which different histories could be considered equal. I also argue that Dietze's proposals about judging societies only by their “own” standards, and basing human dignity on the idea of a “human nature” that could be seen as a “constant,” do not solve the problems she sees with my book and are themselves open to some serious historical and logical criticism. 相似文献
