Many e-commerce companies collect users’ personal data for marketing purposes despite privacy concerns. Information-collecting companies often offer a monetary reward to users to alleviate privacy concerns and ease the collection of personal information. This study focused on the negative effects of monetary rewards on both information privacy concerns (IPC) and information disclosure. A survey approach was used to collect data and 370 final responses were analysed using a two-way analysis of variance and a binomial logistic regression model. The results show that monetary rewards increase IPC when an information-collecting company requires sensitive information. Additional results indicate that building trust is a more effective way of collecting personal data. This study identifies how organisations can best execute information-collection activities and contributes additional insights for academia and practitioners. 相似文献

We have evaluated the extent of public concerns about water management in the Palestinian Territory (PT) through a survey of the main Palestinian newspaper over the last thirteen years divided in three periods: pre (1984–1987), during (1988–1991), and post national uprising period (1992–1996). The public concern in the PT about various water management aspects was clear and influenced by the prevailing political conditions indicating (1) poor concerns in the first and second period where full Israeli military control of the PT and harsh practices prevailed with relatively more emphasis on regional water issues and (2) extensive-strong concerns in the third period when the peace process started and a partial lift of some of the Israeli water practices took place, along with an increased freedom in expressing public concerns which was granted with more emphasis on local issues and problems. Lack and limitation of water available to Palestinians, alternative solutions, and water quality and pollution control constituted the overwhelming majority of the topics of concern to the public for the three periods studied. Palestinian concerns were always greater than regional ones for the three periods and all of the topics considered. Public concern in the PT about all other water management aspects was poor and negligible especially in the first two periods. A massive increase in public concern has been observed in the third period in which the public expressed their concern over most water management aspects, indicating a possible change in public attitude toward water and water management and reflecting the change of the political status by the start of the peace process and the signing of the peace agreements. 相似文献

针对服务集成商公平关切行为, 建立了服务提供商和服务集成商的博弈模型, 分析论证了批发价契约无法实现服务供应链协调的问题, 探讨了“成本共担+收入共享” 组合式契约协调的有效性. 研究结果表明, 成本共担契约和收入共享契约都无法实现服务供应链的协调, 而组合式契约不仅能有效协调服务供应链, 且协调具有一定柔性, 但随着服务集成商公平关切程度的增加, 服务提供商与服务集成商的协调空间变小, 协调柔性减弱, 且对服务提供商更不利. 相似文献

软件体系结构中的横切关注点增加了软件体系结构的复杂性,从而加剧了体系结构演化与维护的困难.这种设计问题可以通过体系结构层面的重构来进行改善.在已有的横切特征分析方法基础上,提出了一种面向横切特征分析的体系结构自动重构方法.该方法首先基于特征与构件之间的追踪关系分析横切特征,然后将与横切特征有直接追踪关系的构件从初始体系结构中提取出来,实现方面构件,完成体系结构重构.在面向方面体系结构描述语言AO-ADL基础上开发了相应的体系结构重构工具,并针对一个业务系统进行了体系结构重构实验.实验结果表明,该方法能有效地实现体系结构横切特征的自动化重构. 相似文献

面向方面的程序设计(Aspect—Oriented Programming,AOP)是在继承OOP基础之上进行改进而来的一种创新的软件设计方法,通过引入方面概念,将应用程序中的核心业务逻辑同其提供支持的通用服务分离开来,从而降低代码之间的耦合度,增加程序的灵活性和可重用性。通过简介AOP在事务处理中的应用,介绍了Spring框架和AOP相结合的事务处理方法。通过采用Spring的AOP框架,使系统的核心业务逻辑和事务管理逻辑分开,从而系统的藕合性大大降低且易于扩展,面向方面编程提高了系统的模块性。 相似文献

AOP在HMIS系统管理中的应用 总被引:1,自引:0,他引:1
医院管理信息系统(HMIS)中的系统管理功能是横跨各子系统的功能模块,而AOP(面向方面编程)是一种允许设计人员模块化横切关注点的新的编程技术,结合医院管理信息系统中系统管理的开发应用,分析了采用OOP技术处理横切关注点引发的问题和困难,介绍了在此情况下采用AOP技术的解决方案,给出了AOP技术在HMIS的系统管理开发中具体的应用示例,并在此基础上讨论了AOP技术的优越性. 相似文献

Well-founded criticisms of the Consumer Reports (CR; 1995) study of psychotherapy include possible bias of the CR sample; limitations of self-report; and the limitations of cross-sectional, retrospective data. Poorly founded criticisms concern "consumer satisfaction" and the claim that the remarkably good effects of long-term therapy resulted from spontaneous remission, that psychotherapy effects were small, and that nondoctoral providers did as well as doctoral-level providers. Both the experimental method (efficacy) and the observational method with causal modeling (effectiveness) answer complementary questions, and they both do so by eliminating alternative possible causes. Efficacy studies, however, cannot test long-term psychotherapy because long-term manuals cannot be written and patients cannot be randomized into two-year-long placebo controls, so the "empirical validation" of long-term therapy will likely come from effectiveness studies. Such studies of long-term therapy, of qualifications of providers, and of clinical judgment versus case management are urgently needed as practice confronts managed care.
