Repeat Consumption of Media Goods: Examining Factors Affecting Repeat Theatrical Viewing of Movies     

Byeng-Hee Chang  Sang-Hyun Nam  Hun Kim 《Journal of Media Economics》2016,29(4):167-180

This study explored the factors affecting repeat theatrical viewing of movies. Integrating content, social influence, and access/competition variables, the analysis reveals that the drivers of theatrical repeat viewing are different from those for box office performance. For example, the effects of genre, transmedia content, and audience review were significant only for the latter and factors such as movie length, critics’ review, and level of news coverage actually played a negative role in the repeat consumption.  相似文献   

Uses and Gratifications,Journalists’ Twitter Use,and Relational Satisfaction with the Public     

Yonghwan Kim  Youngju Kim  Yuan Wang  Na Yeon Lee 《广播与电子媒介杂志》2016,60(3):503-526

This study employed the uses and gratification approach to investigate how journalists perceive relational satisfaction with the public on Twitter, specifically the associations between journalists’ motivations to use Twitter, their Twitter use, and their relational satisfaction with the public. Through a survey of South Korean journalists, this study revealed that journalists’ motivations for Twitter use are positively related to their job-related activities on Twitter (e.g., posting/sharing their news and interacting with audience), which consequently influences perceived relational satisfaction with the public. The findings provide new insight into an increasingly important part of the public’s engagement and news/information flows in the digital media environment. This study expands upon the literature by analyzing how journalists’ motivations for using Twitter and their job-related activities on Twitter are associated with relational satisfaction with the public.  相似文献   

Social Media Type Matters: Investigating the Relationship Between Motivation and Online Social Network Heterogeneity     

Cheonsoo Kim  Jae Kook Lee 《广播与电子媒介杂志》2016,60(4):676-693

This study investigated relationships between social media motivation, relative preferences for social media type, and network heterogeneity, using a U.S. national survey. By classifying social media into the symmetrical and the asymmetrical, we showed that relationship motivation was more likely to be associated with a preference for the symmetrical type, whereas information motivation with a preference for the asymmetrical. Network heterogeneity was positively predicted by relationship motivation but not by information motivation. Finally, a relative preference for the symmetrical type was found to mediate the association between relationship motivation and network heterogeneity.  相似文献

朦胧诗以后:词与物     

刘春 《海南师范大学学报(社会科学版)》2005,18(2):60-64

1985年以后,“朦胧诗人”逐渐引退,“朦胧诗”的单向度写作已经不再为更年轻诗人所满足。随着国人艺术观念的解放,诗歌写作风格也日趋多样。以时间为标志的“第三代”、“70后”、“中间代”、“80后”和以作品价值取向为标志的“知识分子写作”、“民间立场”、“下半身”等命名相继出现;各种写作潮流之间分野日益明显,并引发多次论争;民刊的日益兴盛与互联网的出现,使诗歌写作和发表打破了以前官办刊物的垄断地位。这一切,使近20年来的中国诗坛充满活力。  相似文献   

Reliability and validity of the Myotest® for measuring running stride kinematics     

Cyrille Gindre  Kim Hebert-Losier  Jean-Benoit Morin 《Journal of sports sciences》2016,34(7):664-670

Accelerometer-based systems are often used to quantify human movement. This study’s aim was to assess the reliability and validity of the Myotest® accelerometer-based system for measuring running stride kinematics. Twenty habitual runners ran two 60 m trials at 12, 15, 18 and 21 km·h^?1. Contact time, aerial time and step frequency parameters from six consecutive running steps of each trial were extracted using Myotest® data. Between-trial reproducibility of measures was determined by comparing kinematic parameters from the two runs performed at the same speed. Myotest® measures were compared against photocell-based (Optojump Next®) and high-frequency video data to establish concurrent validity. The Myotest®-derived parameters were highly reproducible between trials at all running speeds (intra-class correlation coefficient (ICC): 0.886 to 0.974). Compared to the photo-cell and high-speed video-based measures, the mean contact times from the Myotest® were 34% shorter and aerial times were 64% longer. Only step frequency was comparable between systems and demonstrated high between-system correlation (ICC ≥ 0.857). The Myotest® is a practical portable device that is reliable for measuring contact time, aerial time and step frequency during running. In terms of validity, it provides accurate step frequency measures but underestimates contact time and overestimates aerial time compared to photocell- and optical-based systems.  相似文献   

An Examination and Validation of an Adapted Youth Experience Scale for University Sport     

Scott Rathwell  Bradley W. Young 《Measurement in physical education and exercise science》2016,20(4):208-219

Limited tools assess positive development through university sport. Such a tool was validated in this investigation using two independent samples of Canadian university athletes. In Study 1, 605 athletes completed 99 survey items drawn from the Youth Experience Scale (YES 2.0), and separate a priori measurement models were evaluated (i.e., 99 items, YES 2.0, YES for Sport [YES-S]). Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) results indicated issues with model fit. Post-hoc modifications improved fit, resulting in a 46-item, 9-factor model with five positive and four negative dimensions. In Study 2, 511 athletes completed the same items. The resultant model was confirmed using both CFA (comparative fit index [CFI] = .911, standardized root mean square residual [SRMR] = .056, root mean square error of approximation [RMSEA] = .040) and ESEM (CFI = .956, SRMR = .023, RMSEA = .034). The resultant University Sport Experience Survey provides a reliable and factorially valid instrument for measuring development in university sport.  相似文献   

Validation of the Microsoft Kinect® camera system for measurement of lower extremity jump landing and squatting kinematics     

Moataz Eltoukhy  Adam Kelly  Chang-Young Kim  Hyung-Pil Jun  Richard Campbell 《Sports biomechanics / International Society of Biomechanics in Sports》2016,15(1):89-102

Cost effective, quantifiable assessment of lower extremity movement represents potential improvement over standard tools for evaluation of injury risk. Ten healthy participants completed three trials of a drop jump, overhead squat, and single leg squat task. Peak hip and knee kinematics were assessed using an 8 camera BTS Smart 7000DX motion analysis system and the Microsoft Kinect® camera system. The agreement and consistency between both uncorrected and correct Kinect kinematic variables and the BTS camera system were assessed using interclass correlations coefficients. Peak sagittal plane kinematics measured using the Microsoft Kinect® camera system explained a significant amount of variance [Range_hip = 43.5–62.8%; Range_knee = 67.5–89.6%] in peak kinematics measured using the BTS camera system. Across tasks, peak knee flexion angle and peak hip flexion were found to be consistent and in agreement when the Microsoft Kinect® camera system was directly compared to the BTS camera system but these values were improved following application of a corrective factor. The Microsoft Kinect® may not be an appropriate surrogate for traditional motion analysis technology, but it may have potential applications as a real-time feedback tool in pathological or high injury risk populations.  相似文献

Critical Thinking, Learning and Confucius: A Positive Assessment   总被引：1，自引：0，他引：1  

Hye-Kyung Kim 《Journal of Philosophy of Education》2003,37(1):71-87

In this paper I argue that Confucius' view of learning in the Analects entails critical thinking. Although he neither specified the logical rules of good reasoning nor theorised about the structure of argument, Confucius advocated and emphasised the importance of critical thinking. For Confucius reflective thinking of two sorts is essential to learning: (1) reflection on the materials of knowledge, in order to synthesise and systemise the raw materials into a whole, and to integrate them into oneself as wisdom; (2) reflection on oneself, (a) in order to ensure that such synthesis, systemisation, and integration proceed in an open-minded, fair and autonomous way, and (b) in order to integrate knowledge with the self, that is, to internalise it until it becomes oneself.  相似文献
