高星级酒店转换壁垒对顾客再购意向的影响研究——兼论顾客承诺的中介作用

顾客满意只能部分解释顾客再购意向。转换壁垒的有效设置可以帮助高星级酒店更好地留住顾客,提升顾客对酒店的利润贡献度和关系嵌入度。本文在回顾国内外相关研究的基础上,以高星级酒店顾客为研究对象,深入探讨了转换壁垒对顾客再购意向的影响。数据分析结果显示,转换壁垒可以划分为程序类、财务类和关系类转换壁垒这三个维度,验证了这一研究结论在酒店业的有效性;关系类转换壁垒对顾客再购意向有着显著的直接正向影响,同时关系类转换壁垒通过情感性承诺间接影响顾客再购意向;程序类转换壁垒与财务类转换壁垒对顾客再购意向没有显著的直接影响,然而,这两类转换壁垒通过顾客承诺间接影响顾客再购意向。     

广州市低收入群体户外活动的时空排斥及其影响机制

低收入群体的社会公平问题是城市发展中的重要问题之一。随着时间地理学的兴起,居民时空间活动为探讨低收入群体的社会排斥提供了一个新视角。文章引入“活动排斥”概念,构建了一套定量衡量居民活动时空排斥程度的指标体系,归纳出时空排斥的衡量因子,将对时空排斥问题从描述统计层面深入到排斥衡量与解释层面。研究发现：低收入群体在活动空间范围与活动等级、丰富度等多个层面与整体评价水平存在差异,户外活动确实受到排斥。这种排斥现象受到受刚性活动时间及个体的社会经济属性等因素的明显制约;居住社区周边的设施服务供给、邻里社交网络等因素分别作用于各个时空排斥维度。     

A Ticking Clock? Preservation and Management of Greenland’s Archaeological Heritage in the Twenty-First Century

ABSTRACT

Evaluating the rate of deterioration at archaeological sites in the Arctic presents several challenges. In West Greenland, for example, increasing soil temperatures, perennial thaws, coastal erosion, storm surges, changing microbial communities, and pioneer plant species are observed as increasingly detrimental to the survival of organic archaeological deposits found scattered along the country’s littoral zones and extensive inner fjord systems. This article discusses recent efforts by the REMAINS of Greenland project for developing a standardised protocol that defines the archaeological state of preservation, the preservation conditions, and asset value of organic deposits. Special emphasis is given to the degradation of materials such as bone and wood that are historically observed to be well-preserved in Greenland but now currently at risk. The protocol provides a baseline for monitoring future changes and will assist archaeologists in Greenland with a procedure for documenting and predicting areas of increasing vulnerability due to a warming climate.     

A tale of three cities: negotiating ethnic identity and acculturation in northwest China

Through extensive interviews with Hui, Han, Dongxiang, and Tibetan migrants and participant observation in northwest China between 2013 and 2015, we examine how the negotiation of ethnic identity influences acculturation strategies in three cultural contexts by scrutinizing the three operational aspects of ethnic identity: perceptions, affections, and behaviors. We argue that the ethnic identity is negotiated at both the group and individual levels as a relation of dialectical unification in regard to fixity and fluidity. At the group level, ethnic identity is relatively fixed and rigid and is perceived by most of the group members as the social norms which normalize ethnic behavior collectively. At the individual level, on the other hand, ethnic identity can be highly flowing and contested from one individual to another. Han identity is generally self-perceived as unmarked, porous, situated, and sometimes even vacuous. Han migrants’ acculturation is more dependent on the cultural context of the host society. Hui and Dongxiang migrants show a strong attachment and affective bonds to their ethnic identity, which is largely based on religious identity. Although Tibetan migrants perceive a complex, place-based identity related to their religion, the grassland, their traditional ways of living, and their language, a Tibetan identity seems to be difficult to fulfill given their economic vulnerability and the contradictions between retaining traditions and being Sinicized in the city.     

WHY DO WE CARE ABOUT POST‐HUMANISM? A CRITICAL NOTE

What is disclosed in the questioning of the human being in post‐humanism? Addressing this question in congruence with Heidegger's questioning of being in Being and Time, we end up with two discoveries: first, that the characteristic of Dasein, as the being of the questioning, already carries the same implications as the post‐human figure, and second, that questioning in this sense is indicative of the effort of realizing anew scientific space for conceptualizing the human being as non‐substantialist. Conceived of in this way, however, post‐humanism is a result of a very human effort indeed.     

新疆宋元时期也木勒遗址出土玻璃的工艺与成分研究

也木勒遗址位于新疆维吾尔自治区塔城地区额敏县,是北方丝绸之路上的重镇,考古发掘确定其为宋元时期的大型遗址。为探讨该遗址出土玻璃的成型工艺和来源,本研究以该遗址中的9个玻璃碎片作为对象,通过观察成型工艺,并利用激光剥蚀电感耦合等离子体原子发射光谱(LA-ICP-AES)技术分析样品的化学成分。结果显示,这批素面透明的玻璃片为无模吹制而成的日常实用器皿,成分上属于钠钙玻璃体系,Na_2O含量低,K_2O含量较高,并含有P_2O_5,助熔剂可能是含有草木灰的混合碱,成分特征与同时期葱岭以西中亚地区、新疆地区生产的玻璃器相似。结合新疆同时期玻璃器发现,多是装饰简洁,出土地点等级一般的普通实用性器皿,说明玻璃器已进入平民的日常生活之中,反映出新疆地方民族政权较中原地区先融合了中西亚将玻璃器作为日常生活用具的文化,形成了与中原玻璃器功用的差异之处。研究结果为丰富国内宋元时期新疆玻璃器的研究资料,揭示新疆地区玻璃器的使用面貌,探讨宋元时期少数民族地方政权的文化交流提供重要信息。     

《帝京景物略》中的岁时民俗记述研究——兼及对当代民俗志书写的一点思考

《帝京景物略》是一个北京人和两个旅居北京多年的他乡人在北京著作的有关北京的一本书,作者在卷二"春场"部分按照时序专门对当时的节日文化和节日生活进行了系统书写,另在一些景观描写中也记述了于兹发生的岁时节日活动。这些记述以较强的可信性、时空结合性、可读性使《帝京景物略》中的岁时民俗记述成为一种优秀的传统民俗志。当前,如何书写怎样的民俗志成为当代职业民俗学者普遍关心的话题,有必要适当加强一下对传统民俗志的研究,从而将传统民俗志对当代民俗志书写的可能贡献落到实处。

基于流形学习与光谱解混的文物表面字迹增强——以云冈第38窟为例

文物表面的文字是了解历史的关键信息，对文物表面文字信息的探索成为文物保护的重要环节。结合流形学习与光谱解混，提出一种新的文物表面字迹增强方法。首先，利用基于流形学习的等距映射方法对预处理后的高光谱图像进行非线性降维，得到信息量最大的灰度图像；其次，分析文字与背景的光谱特征，通过多层非负矩阵分解方法得到字迹丰度图；然后，将二者进行加权平均得到字迹增强图像，再与合成真彩色影像进行HSV融合，得到字迹融合影像；最后，为更好地辨认文字，在字迹增强图像上裁剪文字并做形态学变换，得到字迹提取图。以云冈石窟第38窟的一景褪色文字高光谱图像为例进行了验证，结果表明，该方法能够有效地增强出文物表面的褪色文字，且较其他增强方法效果更好。
