Videogames, visuality and screens: reconstructing the Amazon in physical geographical knowledge

In this article we attend to an emergent practice of visualising GIS data in physical geography using the graphics engine of a videogame, Crysis. We suggest these modes of image-making aid the possibility of imagining and disseminating complex geographical data differently by re-contextualising seemingly abstract mathematical information within a human horizon of embodied meaning. Furthermore we argue these ways of imagining are closely linked to the technology and phenomenology of screens which make the presentation of these images possible. We close by reflecting on the possibility that these technologies are shifting the grounds of vision and the geographical imagination of users.     

乡村游客真实性体验模型研究

关于乡村旅游体验的研究,多以"乡村性"为主题,鲜有基于"真实性"视角的深入探讨.文章基于真实性视角,采用混合研究方法,构建乡村游客真实性体验模型,并进行验证.首先,通过质化研究,构建出"真境""真情""真智""真我"4个维度的概念模型;其次,采用量化研究,验证了"真境""真情""真智""真我"4个维度的合理性,4个维度...     

Tasting cheesescapes in Canterbury (New Zealand)

Food tourism is a means to connect agriculture produce and tourism activity. Food tourism allows destinations to convey the authenticity that comes from their food heritage, which is closely linked to natural and cultural landscapes. Food and landscapes in New Zealand are strongly related to dairy production, cheese production being one of the main features. This study showcases cheesescapes in Canterbury, the largest region in the South Island of New Zealand in terms of milk production. On one hand, thanks to food tourism, the producers can explore ways to diversify their production. On the other hand, visitors are able to identify with the inhabitants of a country and ‘taste’ a portion of its landscape through gastronomy.     

仰韶文化人类遗骸古DNA的初步研究

近20年来, 古DNA研究技术和方法已迅猛发展.目前从古人类残骸中获取DNA序列, 进而讨论人类的演化、亲缘关系和迁移成为分子人类学的一个重要方向.本研究对采自陕西临潼仰韶文化6 000多年前的姜寨遗址第一期和第二期文化层中的古人类残骸进行古DNA提取、扩增和测序, 获得了169 bp的线粒体高变控制区Ⅰ的古DNA片段, 与现代西安人同源性序列有2个位点的突变.另外, 通过在不同实验室进行重复性实验和系统发育分析等方法详细地论证了所获得的DNA序列的可靠性.在所研究的6个姜寨遗址样品中有3个样品获得古DNA序列, 古DNA的提取成功率为50%, 高于一般的古DNA研究材料的提取率, 说明姜寨遗址的人类残骸是研究古DNA的理想材料, 为今后从分子水平上研究姜寨遗址及其他同地区仰韶文化遗址的古人类墓葬及中国古人类分子演化关系奠定了基础.

江苏盐硝类矿产开发现状及产业发展探讨

江苏有丰富的岩盐、芒硝等化工原料类资源。但由于缺乏整体的勘查和开发利用规划,造成了资源的极大浪费,出现了污染等问题。另一方面无序竞争,导致企业效益低下。这些问题,需要通过合理规划开发资源、提高回采率、提高产品科技含量和附加值、综合利用溶腔、积极开拓国内外市场、保护生态环境等渠道加以解决。     

可持续饮食系统的研究进展与理论框架

20世纪以来,伴随农业的工业化和食物链条的“远距化”,典型食物危机事件不断涌现并沿着食物贸易网络蔓延至全球,引发了学界对饮食系统及其可持续性的持久关注。国外地理学界关于饮食系统主要有生产主义、消费主义和关系主义等认识。在梳理已有概念内涵的基础上,将这三类认识归结为不同情境下、特定形式的“身体-食物”关系,进而构建了以饮食原真、饮食安全、饮食健康为内在线索,以去地化和再地化为外在情境的分析框架,并藉此分析饮食系统的演变过程,提炼其可持续逻辑。进一步地,从“身体-食物”与“地方”的关系视角详细阐述了上述三个维度的具体内涵,并归纳了饮食原真与饮食安全、饮食原真与饮食健康以及饮食安全与饮食健康的交叉议题。     

远方的家——中国游客共享型住宿的入住选择与体验研究

共享经济理念的普及和游客对旅游体验的个性化要求,使得旅游共享住宿成为旅游业的重要领域和研究热点。以入住过共享型住宿的中国游客为研究对象,收集在线旅游平台携程网的942篇全球入住游记,形成17万字的研究文本。通过词频词性分析、语义网络分析等内容分析法,探究了中国游客的入住选择因素、体验感知和满意度评价。研究发现,游客选择共享型住宿有较强的求新求异动机,其决策选择是着重考虑性价比、区位等之后的理性选择。游客通过与房东的互动,在这个住宿空间中“家”的感觉和异域新奇体验交织,使其舒适和个性需求得到满足,整体呈现了较高的满意度。最后,在研究结果的基础上提出了共享型住宿的管理建议。     

A GEOGRAPHY OF U.S. INSTITUTIONAL INVESTMENT, 1990

This paper examines the geography of institutional stock ownership for 603 major publicly traded companies. Linkages between cities are created using the stockownership levels between headquarters cities of investors and headquarters cities of firms. Both cartographic and statistical methods show that the urban connections describe a highly selective network of high-order urban centers. New York City is the dominant city, followed by Boston, Los Angeles, Philadelphia, and San Francisco. A simple gravity model, used to test the level of the effect of space on market perfection, explains a substantial portion of the investment-defined network. Differences between the levels of investment by different classes of institutional investors also are revealed.     

Ecotourism and mass tourism in Southern Thailand: Spatial interdependence, structural connections, and staged authenticity

The desire to spend leisure time in natural settings represents a key factor behind the recent and rapid growth of ecotourism. A search by ecotourists for remote landscapes and locations has shaped the way in which geographers have defined ecotourism, but few scholars have explored, in detail, the mechanics of the spatial relationship between ecotourism and mass tourism, two forms of travel usually considered mutually exclusive in spatial terms. Using the island of Phuket — southern Thailands premier resort destination — as a case study, this paper investigates the spatial overlaps and connections between ecotourism and mass tourism and tests the assumption that ecotourism and mass tourism must exist spatially apart in order for the former to succeed. Despite Phukets association with mass tourism, and the small physical distances between built-up mass tourist areas and natural ecotourism settings, the communicative staging of natural authenticity allows ecotourism companies to convey geographical remoteness to tourists. Although ecotourism in Phuket must struggle constantly to overcome the perceptual impact of spatial proximity to resort locations, the tourist markets and business networks of the existing mass tourism industry remain crucial to the survival of ecotourism in this region. Thus, contrary to conventional notions that ecotourism and mass tourism must exist as separate entities, this paper argues that an interconnected, symbiotic, and spatially-contiguous relationship between the two is necessary in the case of Phuket.
