中国农业银行网银表单的可用性问题研究

认知走查作为一种可用性研究方法,是专家将自己"扮演"成用户,通过一定任务对界面进行可用性评估。网上银行最基本的组成元素就是表单,其所有功能都通过用户与表单的交互来完成。本文就以认知走查为基本研究方法,设定一定的任务,查找现有中国农业银行网上银行(个人版)表单存在的可用性问题。最终将走查到的可用性问题汇总并提炼出具有一般指导意义的网银表单设计准则。     

Analysis of heuristic validity,efficiency and applicability of the profile distance method for implementation in decision support systems

This article seeks to enhance acceptance of the profile distance method (PDM) in decision support systems. The PDM is a multiple attributive-based decision making as well as a multiple method approach to support complex decision making and uses a heuristic to avoid computationally complex global optimization. We elaborate on the usability of the method and question the heuristic used. We present a bi-section algorithm, which efficiently supports the discovery of transition profiles needed in a user-friendly and practical application of the method. Additionally, we provide empirical evidence showing that the proposed heuristic is efficient and delivers results within 5% of the global optimizer for a wide range of datasets.

Development and evaluation of a Web 2.0 annotation system as a learning tool in an e-learning environment

The emergence of Web 2.0 technology provides more opportunities to foster online communication and sharing in an e-learning environment. The purpose of this study was to develop a Web 2.0 annotation system, MyNote, based on the Web 2.0 core concepts which emphasize ease of access and active sharing and then to gain an understanding about people’s perceptions of MyNote from a usability perspective. MyNote was employed on multimedia learning objects in a Learning Management System (LMS), and out of the LMS as well in this study. The evaluation results showed that, with factor analysis, interactivity, usefulness, helpfulness, and willingness for future use were categorized to represent the perceptions of MyNote. It was also found that the factors of interactivity and helpfulness were statistically significant to predict the future use of MyNote. Lastly, the habit of taking notes also affected learners’ perceptions of using MyNote.

Evolving the online customer experience … is there a role for online customer support?

This paper advances our theoretical understanding with regard to the online customer experience in a utilitarian context. The aim of this research is to understand if there is a need for online customer support during search for information and services on business support websites. In contrast to previous studies highlighting time distortion as part of the optimal customer experience, the findings of this research illustrate that customers are time conscious during a utilitarian search with the perceived length of time spent on the website influencing the customer experience. Additionally, the perceived length of time spent on the website influences the need to seek online customer support. The outcomes of customers requiring online customer support in relation to the customer experience have been established. The findings provide key managerial implications for economic development agencies and online business support providers on the requirement of online customer support and insight into the time conscious nature of customers in relation to the online customer experience.

广域组织内开放决策支持网格框架

针对政府机构和企业缩减规模的发展趋势,为地理上分布的管理人员进行更高效的跨应用领域决策支持提出一个5层决策支持框架,重点实现组织决策支持（Organization Decision Support,ODS）、提高决策质量,并提供一个公共操作环境以使组织在决策制定的整个生命周期中有效地进行信息协作．该框架以决策任务为主导,扩展传统的ODS框架,把不同的资源规范到一体的参考模型中,引入更多的与决策支持有关的协作模型,可为组织的辅助决策系统建设提供参考．     

The Research about the Role and influence of Teacher emotional support in Online Learning Environment

At the beginning of 2020, the COVID-19came out. Affected by the outbreaks, the universities have to carry out online teaching. Online learning provides students with full freedom and personalized learning space, but at the same time, it also brings problems such as weak feelings between teachers and students and lack of learning experience. To solve these problems, this paper adopts the methods of questionnaire survey, experimental control and behavioral modeling. This paper studies how teachers' emotional support behavior affects students' learning process and learning emotion in online learning environment, and proposes that teachers' emotional support behavior is appealed and desired by students. Positive teachers' emotional support behavior can promote students' learning process and improve students' learning emotion.
