Context-Sensitive Access Control Model for Government Services

During the past two decades, e-government information systems have become less paper-based and more computer-based. Those information systems usually take the form of workflow systems. Due to the large social impact of e-government systems, computer security plays a pivotal role in ensuring its efficiency and effectiveness. Access control is one of the key aspects of computer security. Current access control models do not take into account the context of the system and its environment. In this article, we argue that a formal context-sensitive access control model can improve the development of e-government workflow systems and present a particular context-sensitive access control model. The subject of the article is a specification of the context-sensitive access control model for business processes (COBAC). By using a context-sensitive access control, it is possible to define more sophisticated access control policies that cannot be implemented by existing access control models. The COBAC's context is modeled using Web Ontology Language (OWL) in order to provide formal representation of context, rich representation of diverse contextual information, semantic interoperability between various context-aware systems, and a high degree of inference making. The presented model is applicable in different e-government systems, and supports the definition of access control policies for both simple and complex business processes. The model's prototype is verified by a case study on a real e-government business process—the national petty offense trial proceedings.     

工作情景中的目标取向研究进展

工作背景中的目标取向研究是成就动机理论的重要分支,其研究经历了从单一维度到多维度的过程.早期的目标取向强调个体成就动机、个体水平是主导性的分析层面,随着概念内涵的丰富,研究层次也拓展到人际比较层次与团队层面.由此研究进展趋势和路径看,未来目标取向的研究主要是团队或更高层次的把握、情景因素与目标取向的关系以及不同层次的形成与交互关系.

解决两个问题 提高中职生作文质量

制约中职生作文质量的因素很多,涉及的方面很广,提高作文质量要做的工作也很多,但我觉得首先要解决两个问题。第一是要解决学生对作文存在的畏难心理,第二是帮助学生提高运用素材的能力。这是中职生写作文时普遍存在的两个基础问题,而提高运用素材的能力则更为重要。     

论信息技术教学的必要性

21世纪是一个信息技术高度发达的时代。信息的全球化,使得信息产品、信息服务成了每个国家,每个人必不可少的一部分。掌握信息技术,成了每个人生存的基础。小学作为个人成长的重要时期,信息技术教育应成为小学教育中重要的一部分。本文从小学信息技术对提高学生学习兴趣、快速掌握现代信息、开发小学生智力等方面作了探讨。     

基于个体差异的报童群体决策研究

通过实验研究群体决策和大五人格对报童订购的影响。研究表明大五人格中开放性维度能很好地预测个体和群体决策者的订购行为。在个体实验中，开放性越高的个体更不易产生锚定效应，其他四种人格特性与锚定偏差无显著关系；在群体实验中，群体的开放性得分均值、群体中高开放性成员所占的比例与锚定偏差呈负相关关系。通过比较两种实验结果，发现群体锚定倾向明显小于个体锚定倾向，而群体决策并没有优于个体决策。该研究结果对企业人员招聘、构建决策团队及降低决策偏差有一定参考价值。     

ENTREPRENEURIAL EXPORTERS: The Canadian Experience

The increasing globalization of commerce has presented incalculable challenges as well as opportunities for small- and medium-sized enterprises, particularly exporting firms. This study focuses on the relationship between entrepreneurship and successful export marketing performance, testing the hypothesis that entrepreneurship is positively related to such performance. The research reveals that entrepreneurial behavior is positively correlated with export marketing behavior, suggesting both firm and government actions to boost competitiveness.

Inter-Satisfaction between Website and Automated Call Distribution (ACD) Systems

Websites and an Automated Call Distribution (ACD) system in a call center are both considered important customer relationship technologies. Integrating concepts from information systems quality and trust transference theory, this paper introduces the concept of inter-satisfaction: the extent to which customer satisfaction with a website leads to satisfaction with an ACD and vice versa. It is hypothesized that dissatisfaction with either the website or the ACD influences potential brand-switching behaviors. A model, largely drawing upon concepts of user satisfaction as developed in information system research, is presented. The model is then tested using data from passengers using Low Cost Carriers (LCCs) in South Korea, specifically 366 passengers at the Jeju International Airport, who experienced both their airlines’ website and call center. A structural equation modeling analysis demonstrates that satisfaction with the website transfers to satisfaction with the ACD system, but not vice versa, and that only dissatisfaction with the website creates a brand-switching intention.
