Fans＇ online Services Expectations and Experiences： The Case of National Basketball Association

引用

Journal of Sports Science 2013年第1期1卷 1-14页

作者： Yann Abdourazakou Nicolas Lorgnier Shawn o'rourke Norman o'Reilly Gashaw Abeza Department of Sport Administration Canisius College NY 14208 USA School of Business Ohio University Athens 45701 USA University of ottawa 125 University Private Ottawa ON KIN 1A2 Canada

The purpose of this study was to examine the online service expectations of fans of professional sport. Participants were asked about their online experience and the impact it had on a number of variables, including satisfaction and service quality. Three dimensions regarding the online experience were identified. First, the core product represents the set of items influencing fans＇ perceptions of the quality of the game; second, the ancillary products characterizing the derivative products related to the game; and finally, the efficiency of support services used to access the core and ancillary products online. The study found that although respondents reported higher expectations of the core product than of the ancillary products, their expectations of support services efficiency were also very high. Understanding fans＇ specific expectations enables sport organizations to identify and fulfill fans＇ expectations of their online experience. The study＇s results are reviewed in the context of previous research and practice to suggest a future research protocol to aid managers＇ understanding of online fans＇ expectations and satisfaction with service provided.

Wars as Dividing Significance of the Lines？ Rethinking the Sino-Japanese War in Twentieth Century China

引用

Frontiers of History in China 2018年第1期13卷 73-89页

作者： J. megan Greene Department of History University of Kansas Lawrence KS 66045 USA

Historical periodization frequently takes wars as turning points--as ruptures that signify the end or beginning of an era. At the same time, front lines have often been taken as boundaries that contain the activities of one side or the other. Thus, discontinuity and disjuncture rather than continuity and fluidity have o-en been the points of emphasis among historians who have taken war events as turning points, or who have seen lines of combat as impermeable. A new focus on the Sino-Japanese War period has begun to reveal ways in which that moment served not as an interruption but as a part of longer term processes of change and development that characterized China＇s mid-twentieth century. It also permits us to gain a deeper understanding of the fluidity of human movement and socio-economic interaction that frequently boundaries and to think about similarities various Chinese spaces. The aim of this paper crossed both political and military linkages, and differences between is to consider ways in which the new generation of scholarship on the Sino-Japanese War period offers new ways of thinking about continuity, change, similarity and difference across both temporal and physical boundaries that have served as the parameters for much of the earlier scholarship on the period. To this end, the paper examines recent literature on the Sino-Japanese War period, as well as literature that crosses that period, to examine ways in which this historiography has challenged conventional periodizations and political and geographical delineations

地震波影响的区域要比永久性地土移动所发生的区域广,破坏管道系统薄弱部分的可能性大;但是永久性地土移动比地震波产生的后果要严重得多。由地震引起的大规模永久性地土移动,如地表断裂、沙土液化、塌方等对输油管道的损坏最为严重。从管道损伤的角度来评价损坏的原因,对于规定地震危险等级和工程设施的定点都很重要。例举了1964年阿拉斯加、1971年圣费尔南多、1976年危地马拉和1987年厄瓜多尔发生的地震对石油设施的影响以及从这些地震中得到的教训。
