Parents of Traditionally Aged Community College Students: Communications and Choice

Five suburban community colleges in a metropolitan area collaborated on a survey to parents of high school graduates of the class of 2002 who attended the colleges in fall 2002. The study was undertaken to learn more about parents roles in their students selection of community colleges, to give insights and information about this important community college constituency, and to assist community colleges to shape more effective ways to foster positive and supportive opinions among parents of potential students. Parents want the community college to provide students with credits and grade point averages enabling transfer, overestimate their students academic skills as measured by course placement tests, engaged in a number of college-choice activities, and indicate that factors associated with lifestyle and money were major reasons for selecting the community college. Associations between parents social capital and perceptions of their students academic abilities were found for a number of dependent variables examined. The study also revealed important differences in how participating institutions record and calculate key measures such as credits earned and grade point averages.

融合主题指纹的科学知识系统计量语言学研究

【目的/意义】从计量语言学视角描述和揭示融合主题指纹的科学知识系统的语言分布规律,并选取语料进行验证,深化情报检索语言的理论和应用研究,也为知识抽取研究提供理论基础和实验素材。【方法/过程】以生物医学领域的"疾病"、"精神病学和心理学"和"现象和过程"三个类别分支为入口,选取乳腺癌、焦虑抑郁、免疫作为案例,并量化分析其代表性。运用齐普夫定律(Zipf’s Law)和希普斯定律(Heaps’Law)解释验证由主题指纹映射的科学知识系统的计量语言学特征。【结果/结论】融合主题指纹的科学知识系统具有计量语言学特征,符合科学信息的离散分布规律和演化定律,具有较好的科学性和稳定性。     

职业体育赛事球迷观赛动机的国外研究综述

职业体育中高度变化的商业环境凸显了在管理、营销和服务等领域研究消费者动机的重要性。国外学者对球迷观赛动机进行了深入的研究,并取得了很多有价值的研究成果。本文从球迷观赛动机的3个组成构面:球迷忠诚度、球迷内在动机和球迷外在动机,分析动机因素对职业体育赛事消费的影响;基于对国外现有研究的梳理和述评,本文进一步解析上述研究成果对我国职业体育的管理体制、运行机制、塑造品牌、观众服务等方面的可应用性,并提出学术研究方向上的新建议。     

Tennis superstars: The relationship between star status and demand for tickets

Akin to other sports, professional tennis is urged to adopt a consumer-centred strategy and understand the influence of the star status of elite players on demand for its core product. Measuring the impact that tennis players have on demand for match attendance remains a key element towards achieving that goal. Using data from the Australian Open ticket sales, the authors demonstrate how individual players have influenced stadium attendance at the Grand Slam. Findings indicate that some players are associated with a strong positive impact on demand for tickets, above and beyond their performance ratings, reflecting their value to the Australian Open. The authors discuss how this star status can be used to inform business decisions related to tournament management, match scheduling, and determining player appearance fees, to ultimately drive better commercial outcomes and deliver a world-class sporting event. The findings have implications for tournament organisers, player managers and those that market player activities.     

偶次非球面镜在指纹采集系统中的应用研究

指纹识别的技术实现,其理论基础就是光电数字图像处理,故采集到的指纹图像的质量好坏对后续图像处理的难易至关重要。设计出清晰、畸变小甚至无畸变的指纹识别镜头是制造指纹识别仪的关键。随着光学加工技术的发展,目前非球面镜片已广泛应用于光电产品的各个领域,本文采用普通材质的棱镜及非球面透镜,可使指纹采集系统的畸变控制在0.2%以内。     

基于二次匹配的指纹识别方法的研究

在前人的研究成果的基础上,对指纹识别的各个过程,包括指纹图像预处理、指纹图像特征点提取、指纹匹配等相关算法进行了研究。特别是在指纹图像匹配阶段,为了得到较好的效果,采用了两次匹配的过程,第一次匹配使用传统的基于特征点的匹配方法,能够迅速地去除差距很大的图片和效果较好的匹配图片,而第二次匹配使用了基于可变界限盒的串距离匹配方法,这种方法能够更好地适应指纹图像的非线性形变等情况。通过这样的两次匹配,能够得到比较满意的匹配结果。
