Multi-objective Trip Recommendation Based on Check-in Data and Traffic Tools

In general, users want to spend little money to visit as many attractions with different categories and high scores as possible. In order to solve this problem, this paper proposes a multi-constrained and multi-objective pruning algorithm. First, it analyzes users' historical check-in data, and proposes a rating mechanism of scenery spot based on users' check-in data-know users’ preferences and popularity of scenery spot. And this paper considers the different choices of vehicles, because the transfer between attractions will have different transfer time and costs. Finally, according to users’ needs, the MCPA-MO algorithm is used to calculate an optimal travel route for the user. The recommendation algorithm was implemented and evaluated using the real data on the Foursquare and the information on the famous attractions in Chengdu on the Horse Cell as the data set. Experimental results show that it can recommend personalized trip that meet the actual needs of users.

电信企业ARPU值分析

本文从电信运营企业ARPU值的基本概念出发,比较深入地分析了ARPU值对于固定和移动通信企业利润的影响;揭示了在一定的条件下,为保持已有利润水平,APRU值的用户数量之间的变动关系;提出运用ARPU值进行比较分析时应该注意的问题.     

基于真实感框架的自然用户界面反馈设计方法

以自然用户界面的真实感框架为研究出发点,深入分析自然用户界面的反馈行为,提出一种自然用户界面的反馈设计方法。基于该方法设计并实现了一个原型系统Flying Kite。构造对比实验从主客观两个方面比较了Flying Kite系统与采用普通方法构造的K-Kite系统间的用户体验差异。实验初步验证了反馈设计方法的有效性,该方法可以显著地提升人机系统的用户体验,使自然用户界面的优势得到充分体现。     

工作不安全感对用户抵制信息系统实施的影响

用户抵制是信息系统领域的一个热点话题。采用问卷调查方法收集12家企业266份信息系统终端用户及其直接主管配对样本,运用SPSS 19.0和AMOS 17.0等软件以及多元层级回归等方法,以压力-情绪理论和情感事件理论为基础,探讨工作不安全感对用户抵制信息系统实施的影响,重点分析积极情绪和消极情绪的中介作用以及不确定性规避的调节作用。研究结果表明,工作不安全感对用户抵制有显著正向影响,积极情绪和消极情绪在工作不安全感与用户抵制之间起完全中介作用,不确定性规避负向调节工作不安全感与积极情绪之间的关系,用户不确定性规避越高,工作不安全感与积极情绪的负向关联越强;不确定性规避正向调节工作不安全感与用户抵制的关系,用户不确定性规避越高,工作不安全感与用户抵制的正向关联越强;不确定性规避正向调节工作不安全感通过积极情绪对用户抵制的间接效应。研究结果为用户抵制研究提供了新的视角,对管理实践具有一定的指导意义。     

基于开源软件的用户创新动机研究综述

开源软件作为一种有悖经济学常理的用户创新方式,从出现以来就受到经济、法律、社会、心理以及计算机科学等领域的学者们的持续关注。通过回顾已经取得的研究成果,可以发现其动机分为外因诱致和内因驱动。前者认为参与者都是为了牟取某种潜在的利益,且这种利益要大于为此付出的成本。后者内因驱动由一系列的动机组成:自我愉悦的感觉、参与的欲望以及纯粹的理想信念等等,同时展望了其他需要在今后的研究中加以探索的问题。     

基于用户反馈的Web多媒体数据源的选取

针对Web多媒体主题的特点采用用户反馈机制,提出了用户推荐可信度度量准则,准确获取了多媒体数据源核心质量维度,建立了相关的质量模型。实验结果表明,该方法在多媒体数据源选取时,准确性较高且计算量较小。     

Service users and carers’ involvement in social work education: lessons from an English case study

Within the larger context of the search to improve social work practice in Europe, this article presents a case study of a UK innovation in social work education with the potential to radically change social work practice. Following governmental requirements, Anglia Ruskin University has introduced systematic involvement of service users and carers in the training of a new undergraduate degree since September 2003. The conceptual and value base, the structure, staffing, and main activities are outlined; the main achievements and obstacles are highlighted. Mindful of the danger of slipping into tokenistic involvement, the project has included an action research evaluation component exploring the views of all the project's stakeholders thus establishing the project as an evidence-based educational innovation. The findings highlight the value of service users and carers’ involvement on the qualifying social work degree, of the action research design of the evaluation, and the steps needed for the cultural change required for such an involvement to become more comprehensive and embedded in the degree.     

形合、意合的普遍性与相对性及其深层动因

形合与意合是语言构建的外在表征，也是英汉两种语言之间的重要区别特征。指出在句子及句子以下层面是英语重形合，汉语重意合，而在句子以上（语篇）层面，英语重形合、汉语重意合只是一个相对概念，是语用主体出于交际目的之需要在实际话语活动中的语用选择，这种选择受认知环境、文化认知范式、审美取向的影响和制约。     

Service user/survivor-led research in mental health: epistemological possibilities

This paper considers possible epistemologies for user-led and survivor research by drawing on four discourses: the mainstream English tradition, Canadian Mad Studies, critical theory more generally and feminist standpoint epistemology. It discusses general, universalising epistemologies, the extent to which these characterise the discourses at stake and the problems with knowledge claims that rest on such singular conceptualisations. The institutional and political concomitants are considered. The paper has an additional double aim: to engage with survivor scholarship around critical theory and to insert that scholarship into the field of critical theory itself in a novel manner.
