Methodological problems of intercultural comparisons of retail environments     

Jonathan Reynolds 《GeoJournal》1998,45(4):245-254

The internationalising activities of retailers have tended to precede the theoretical contributions of academics. This is particularly the case for the cultural context within which retail internationalisation takes place. Following an examination of the growth of international retailing activity, the article reviews generic difficulties in studying inter-cultural differences before considering the specific steps which retail practitioners have taken to understand the comparative characteristics of retail and consumer markets through the growth of geodemographic and lifestyle analysis. Finally, we relate one of the most significant integrative intercultural theoretical instruments to the case of retail internationalisation within Western Europe. We find that significant insights into retailer behaviour and strategy can be gained from an understanding of the culturally-specific characteristics of the activity.

凡纳滨对虾常见养殖模式下养殖后期浮游植物及理化因子的变化   总被引：1，自引：0，他引：1  

张才学  劳赞  刘玉莲  区兆伟 《广东海洋大学学报》2007,27(4):38-44

对凡纳滨对虾几种常见养殖模式后期的浮游植物及理化因子进行了调查研究,结果表明,浮游植物的群落特征因养殖模式、养殖时间、不同的环境条件等原因变化很大,其群落组成由最少的11种到最多的28种不等;其优势种与次优势种中以蓝藻门、绿藻门、硅藻门为主,甲藻门、裸藻门偶有出现,主要优势种有小环藻、波吉卵囊藻、中肋骨条藻、颤藻、林氏藻、裸甲藻、胶球藻、小席藻、腔球藻等,浮游植物群落的生物多样性由高至低依次为高位池分级精养模式、海水土池粗养模式、低盐度养殖模式、咸淡水半精养模式、工厂化集约养殖模式、高位池集约养殖模式,多样性指数与优势度呈显著的负相关,而与均匀度呈显著的正相关。细胞密度485.9×104~35459.8×104L-1,在高密度精养模式中,浮游植物的密度与无机氮、硫化氢含量的变化在早期呈负相关,在后期则几乎同步增长;在低密度养殖模式中,浮游植物的密度与无机氮、硫化氢含量的变化始终呈负相关。各养殖模式pH值的变化与浮游植物的密度呈正相关。综合分析表明,高密度养殖宜采用高位池分级精养模式,低密度养殖宜采用海水土池粗养模式。  相似文献   

石窟寺文物的数字化保护与利用     

李敏  刁常宇  葛云飞  裘霖山  李丽 《遥感学报》2021,25(12):2351-2364

随着信息技术的飞速发展,石窟寺文物的数字化保护与利用引起了国内外的广泛关注。文章从石窟寺文物数字化采集、保护和利用等方面进行系统梳理,重点分析石窟寺文物数字化保护中三维信息获取、三维重建评价以及三维打印等相关前沿信息技术的应用现状。并针对石窟寺文物数字化保护和利用工程实践中的难点,给出采用激光脉冲三维采集细部结合多视图重建采集整体形状的三维重建结合三维打印的解决方案。同时,针对摄影测量计算过程中可能出现的整体形状偏差,采用脉冲式激光三维扫描仪在石窟中进行整体扫描来建立石窟三维形状的框架,以对多视图重建计算中的空间解算误差进行约束。其中,提出了基于关键参数一致化的分布式集中约束调整方法,在保障精确度的同时得到更好的计算效率。然后通过云冈石窟和龙门石窟字化保护和利用的经典案例,具体分析工程实践中的难点,并探讨以上解决方案的可行性。综合考虑成本与效果等多种因素,该方案是当前技术条件下性价比相对较高,同时可以兼顾色彩与质感原真再现的解决思路。最后对未来趋势进行展望并给出相关技术和应用建议。  相似文献   

国外商业绅士化研究进展及其对本土研究的启示   总被引：1，自引：0，他引：1  

孙洁  宋伟轩 《世界地理研究》2021,30(5):1096-1105

商业是城市中最活跃,并且对城市发展和空间重构产生重要影响的功能之一。近20年来,随着产业转型与城市更新实践,日益突出的商业绅士化现象愈发引起国外学术界关注。同时,多源数据和定量分析方法的利用,促进了商业绅士化专题研究逐渐增多。商业绅士化的发生背景、表现特征、推动主体与形成机制,以及商业绅士化导致阶层置换、加深种族隔离等社会空间效应是主要的研究内容。通过对国外商业绅士化研究文献的梳理,以期展示城市商业高档化重构的机理以及绅士化演进的复杂性。基于当前我国城市转型和消费转型的特征与趋势,尝试提出对商业绅士化本土研究方向和方法的启示。  相似文献   

Spatial-temporal patterns of China’s interprovincial migration, 1985-2010     

LI Yang  LIU Hui  TANG Qing  LU Dadao  XIAO Ningchuan 《地理学报》2014,24(5):907-923

Migration plays an increasing role in China's economy since mobility rose and economic restructuring has proceeded during the last three decades. Given the background of most studies focusing on migration in a particular period, there is a critical need to analyze the spatial-temporal patterns of migration. Using bicomponent trend mapping technique and interprovincial migration data during the periods 1985-1990, 1990-1995, 1995-2000, 2000-2005, and 2005-2010 we analyze net-, in-, out-migration intensity, and their changes over time in this study. Strong spatial variations in migration intensity were found in China's interprovincial migration, and substantial increase in migration intensity was also detected in eastern China during 1985-2010. Eight key destinations are mostly located within the three rapidly growing economic zones of eastern China (Pearl River Delta, Yangtze River Delta and Beijing-Tianjin-Hebei Metropolitan Region), and they are classified into three types: mature, emerging, and fluctuant origins, while most key origins are relatively undeveloped central and western provinces, which are exactly in accordance with China's economic development patterns. The results of bicomponent trend mapping indicate that, in a sense, the migration in the south was more active than the north over the last three decades. The result shows the new changing features of spatial-temporal patterns of China's interprovincial migration that Fan and Chen did not find out in their research. A series of social-economic changes including rural transformation, balanced regional development, and labor market changes should be paid more attention to explore China's future interprovincial migration.  相似文献   

Toward an Integrative Framework for Environmental Justice Research: A Synthesis and Extension of the Literature     

Damayanti Banerjee 《社会与自然资源》2014,27(8):805-819

Over three decades, environmental justice scholarship has examined justice movements through diverse perspectives shaped by their research traditions and disciplinary boundaries. This article distills three themes of justice from these research traditions in order to propose a four-dimensional environmental justice model. The proposed model includes four justice-seeking strategies—cultural justice, material justice, processual justice, and political justice—that movement groups adopt to mobilize their claims. I apply this model to the study of an environmental movement in Land Between the Rivers, Kentucky. Research findings from the case study concludes that movement strategies are plural and changeable and that justice is best conceived as a repertoire of justice-seeking strategies that are influenced by political alliances, economic preconditions, and cultural contexts.  相似文献   

In Situ Maintenance of Traditional Ecological Knowledge on Malekula Island,Vanuatu     

Joe McCarter  Michael C. Gavin 《社会与自然资源》2014,27(11):1115-1129

Traditional ecological knowledge (TEK) guides resource management across the globe, but is at risk amid social and ecological change. This has prompted numerous calls for TEK maintenance efforts, but these remain largely unexamined in the literature. Here, we discuss three examples of in situ TEK maintenance from Malekula Island in Vanuatu, locally known as kastom schools. Based on qualitative data, we find that the kastom schools may create several opportunities to maintain TEK (e.g., establishing local control over education), and argue that they represent the creative and adaptive management of tradition in dynamic social–ecological contexts. However, a number of challenges, both practical (e.g., lack of funding) and epistemological (e.g., changing modes of cultural transmission), threaten the efficacy of the kastom schools. We argue that in situ modes of TEK maintenance have promise, but that issues of power and heterogeneity require serious consideration if such measures are to succeed.  相似文献

地方文化环境与大学教学科研融合发展的模式初探——基于英美若干研究型大学的经验研究     

孔翔  于良全 《世界地理研究》2014,(1):167-175

教学科研的深度融合是研究型大学的共同特点,但各个大学实现融合的模式仍存在差异。本文拟基于地方文化传统和周边产业发展需求,探索地方对大学主导功能的影响,并结合对英美典型研究性大学的案例剖析,研究不同大学教学科研融合发展的主要立足点不同的内在原因。研究显示,地方不仅为大学的发展提供资金和基础设施等方面的支持,也需要大学提供人力资本、知识创新等方面的服务,因此,大学的主导功能与地方文化经济环境密切相关,而教学科研的融合则往往立足于大学的主要功能。例如,牛津大学以人才培养为重点就深受英国传统文化的影响,哈佛在基础研究方面的卓越贡献也与其追求真理的文化传统有关,而斯坦福大学以服务产业发展促进人才培养与科研紧密融合的模式也受到实用教育理念的影响。总的看来,研究型大学都应该力促教学科研的深度融合,这是其承载文化传播和知识创造功能的基础,但就具体大学而言,很有必要适应特定地方的文化环境,探索适合的教学科研融合发展模式,而不要陷入盲目模仿的误区。  相似文献   

基于土地发展权的历史文化遗迹所在地区农地保护策略探究     

王征 《上海国土资源》2014,(1):9-13

目前我国历史文化遗迹所在地区开发用地失控的原因,从体制方面讲,乃是由于规制手段不够健全、管理体制不够顺畅、城镇化和旅游经济发展进程的阶段性等问题所致;从微观经济层面而言,还在于农民缺乏保护农地的经济诱因、农地转向开发用地收益更高、相关利益集团的势力影响等因素在起作用,故而农地流转成开发用地不可避免。所以应当借鉴海外土地发展权制度,在历史文化遗迹所在地区内落实土地发展权的补偿机制,对开发用地实行有效的管制。具体来说,应当从法律上明确土地发展权的地位,将农地保护与当地的经济社会发展有机协调起来,推行土地使用管制,建立完善土地发展权交易机制,同时有效控制农地流转为开发用地的隐性交易行为。  相似文献
