In recent years, collaborative filtering, a recommendation algorithm that incorporates a user’s data such as interest, has received worldwide attention as an advanced learning support system. However, accurate recommendations along with a user’s interest cannot be ideal as an effective learning environment. This study aims to develop and evaluate an online English vocabulary learning system using collaborative filtering that allows learners to learn English vocabulary while expanding their interests. The online learning environment recommends English news articles using information obtained from other users with similar interests. The learner then studies these recommended articles as a method of learning English. The results of a two-month experiment that compared this system to an earlier collaborative filtering system called “GroupLens” reveal that learners who used the collaborative filtering system developed in this study read various news articles and had significantly higher scores on topic-specific vocabulary tests than did those who used the previous system.  相似文献

The purpose of this study is to understand how professional sport organizations might influence consumer voluntary behavior through their corporate social marketing (CSM) initiatives by focusing on the role of corporate credibility. The study examined consumer responses to environmental initiatives by two professional sport teams, and showed that organizational and program characteristics were associated with the corporate credibility of the teams in supporting environmental protection (i.e., environmental credibility). Environmental credibility, in turn, was found to have a positive association with consumer pro-environmental behavior measured by daily recycling involvement and recycling intentions during the teams’ home games. The results further revealed that environmental credibility was more strongly associated with recycling intentions during games for respondents who were less involved in environmental issues. Together, these findings suggest that professional sport organizations can be an effective vehicle for socially beneficial behavior by increasing their credibility in CSM involvement.  相似文献

This paper describes the development of a software program that supports argumentative reading and writing, especially for novice students. The software helps readers create a graphic organizer from the text as a knowledge map while they are reading and use their prior knowledge to build their own opinion as new information while they think about writing their essays. Readers using this software can read a text, underline important words or sentences, pick up and dynamically cite the underlined portions of the text onto a knowledge map as quotation nodes, illustrate a knowledge map by linking the nodes, and later write their opinion as an essay while viewing the knowledge map; thus, the software bridges argumentative reading and writing. Sixty-three freshman and sophomore students with no prior argumentative reading and writing education participated in a design case study to evaluate the software in classrooms. Thirty-four students were assigned to a class in which each student developed a knowledge map after underlining and/or highlighting a text with the software, while twenty-nine students were assigned to a class in which they simply wrote their essays after underlining and/or highlighting the text without creating knowledge maps. After receiving an instruction regarding a simplified Toulmin’s model followed by instructions for the software usage in argumentative reading and writing along with reading one training text, the students read the target text and developed their essays. The results revealed that students who drew a knowledge map based on the underlining and/or highlighting of the target text developed more argumentative essays than those who did not draw maps. Further analyses revealed that developing knowledge maps fostered an ability to capture the target text’s argument, and linking students’ ideas to the text’s argument directly on the knowledge map helped students develop more constructive essays. Accordingly, we discussed additional necessary scaffolds, such as automatic argument detection and collaborative learning functions, for improving the students’ use of appropriate reading and writing strategies.

In this mixed methods research, the authors examine a unique type of small-scale event – a charity-affiliated sport event – and define and measure its social and charitable impacts as perceived by residents. Findings from interviews (N = 37) and surveys (N = 459) with residents indicated that the event’s social impacts can be defined by its capacity to develop social capital, enhance collective identity and pride, and promote sport, health, and well-being. Three types of charitable impacts also emerged, including empathy for cause, informational support, and tangible support. Of them, empathy for cause, which addresses a central social issue in the host community, had the strongest association with residents’ perceptions of social impacts. These results provide evidence of a variety of positive impacts that a charity-affiliated sport event has on a community, which can be used to bolster appeals for corporate sponsorship and government support to assist in event delivery.  相似文献

Building upon scholarly work on corporate associations, social identity, and corporate philanthropy, this study aimed to: (1) identify the effect of perceived corporate ability (CA) associations of professional sport organizations (PSO) on consumer support of their nonprofit partners and (2) understand communication strategies that enable PSOs to gain greater business benefits from their philanthropic activities. The results of an experiment supported the role of perceived CA in influencing consumer intentions to donate to a PSO's nonprofit partner, and further showed that this perception had a greater effect when respondents’ identification with the PSO was low. The finding also indicated that a message describing a PSO's donation of a large amount of money for a cause could create positive attitudes toward the PSO. These findings extend recent work on professional sport philanthropy by demonstrating that—under certain conditions—such an activity can enhance benefits for both PSOs and their nonprofit partners.  相似文献

The sport participation rate has been shown to decrease with age in many countries. In Japan, however, the elderly sport participation rate has increased over the last decade and is the highest among all Japanese. This study investigated whether the cohort effect generated by the shared experience of hosting the Tokyo 1964 Olympic Games during their youth can explain the increased sport participation of elderly Japanese. Data from the Japanese National Sport-Life Survey over 20 years were analyzed through regression analysis. The results show that, after controlling for demographics and other determinants of sport participation, individuals who experienced the Tokyo 1964 Olympic Games participated in sport more frequently than other generations.  相似文献
