简介:LibQUAL+TM是针对高校及研究型图书馆设计的以读者知觉体验为中心的服务质量评价模型,在借鉴国内部分图书馆采用.LibQUAL+TM进行服务绩效成功评价的基础上,以广东交通职业技术学院图书馆为测评对象,对其服务绩效进行了评价和分析。
简介:基于用户的图书馆服务质量评价体系LiQUALi+TM,构建包含数字资源、服务效果、馆员、移动设备及网络环境4个方面共16个指标的高校移动图书馆服务质量评价模型.并以此为基础,对西安交通大学移动图书馆开展问卷调查,进行数据分析,提出改进高校移动图书馆服务质量的有效措施.
简介:首先,从LibQUAL+的开发与演进、LibQUAL+分数的真实性检测、LibQUAL+分数的解释、LibQUAL+分数的实践应用、开放式评论的量化、LibQUAL+分数的影响因素、LibQUAL+的质疑及LibQUAL+精简模型方面对2000年至2009年国外学者在LibQUAL+方面的主要研究成果进行梳理,然后,对国外学者的相关研究特点进行了归纳。
