每年堵住400万——中国医学科学院肿瘤医院信息化见效益

“通过计算机管理后,避免了跑、冒、滴、漏现象。以前医院存在许多人情方,也存在采集数据滞后现象,病人出院了,检查检验报告才送到病房,导致漏费;或冒充病人开检查单、检验单,费用没有录入。肿瘤医院一年收入约4个亿,如果医院存在2％的跑、冒、滴、漏的现象,则就有800万的跑、冒、滴、漏。通过计算机管理后,就算堵住一半的漏洞,则每年就能创收400万。”中国医学科学院院肿瘤医院计算机室主任李怀成如是说。     

改造医院信息系统加强医院控费管理

通过对各检查科室程序和HIS系统部分程序修改,只有交费或记账的患者才能打印报告,从而使得漏费控制从"事后控制"转变为"事前控制",为医院创造可观的经济效益。同时实现了两者无缝联接,达到信息共享。

Inter-consortia battles in mobile payments standardisation

Mobile payments can be seen as an innovation service offered by key players from the financial and mobile communication industries. Many believe that standards ensure the success of mobile payments. However, actors with heterogeneous interests cause the complexity in standards-setting process and, therefore, the absence of standards for mobile payments. Various groups have been formed to generate standardised solutions for mobile payments. This paper describes and analyses the role of these groups and how they influence the development of mobile payments. Five consortia are explored in min-case analysis. They are the Mobile Payment Forum, the Mobey Forum, Simpay, PayCircle, and the European Committee for Banking Standards. The existence of these consortia has instigated inter-consortia competition. As a result, there are three types of mobile payments developments identified: bank-account based, telecommunications companies billing-based, and credit-card based. The implications of the developments are discussed with the help of interpretive theory.

Utilizing national public-key infrastructure in mobile payment systems

Payments are the locomotive behind any business domain. It has been predicted that mobile payments will become one of the most successful mobile services, and the security of payments is an important requirement. However, it is difficult to strongly authenticate mobile users remotely and provide an adequate level of non-repudiation of transactions. In this article, we argue that a nationwide public-key infrastructure supported by governmental bodies can be used in a mobile payment system. Not only does it provide strong security, but it also makes the system open to any mobile user, merchant, or financial service provider. Two payment protocols are described: one for virtual point-of-sale payments, and one for vending machine payments. We argue that such a system can be implemented using open development platforms, and its performance is adequate for enabling swift transactions. A prototype of a system which accepts virtual point-of-sale payments is implemented, and its performance and usability are evaluated.     

Exploring consumer adoption of mobile payments – A qualitative study

This paper presents a qualitative study on consumer adoption of mobile payments. The findings suggest that the relative advantage of mobile payments is different from that specified in adoption theories and include independence of time and place, availability, possibilities for remote payments, and queue avoidance. Furthermore, the adoption of mobile payments was found to be dynamic, depending on certain situational factors such as a lack of other payment methods or urgency. Several other barriers to adoption were also identified, including premium pricing, complexity, a lack of critical mass, and perceived risks. The findings provide foundation for an enhanced theory on mobile payment adoption and for the practical development of mobile payment services.

Climate Coalitions in an Integrated Assessment Model

An analytically tractable approximation of a numerical model is used toinvestigate coalition formation between nine major world regions withregard to their policies for greenhouse gas emission reduction. Fullcooperation is not individually rational. Assuming non-transferableutility, side payments do not ensure full cooperation either. Withoutside payments, the largest stable coalitions are small and consist ofsimilar regions. With side payments, the largest stable coalitionsexclude either the main culprits or the main victims of climate change.In all cases, optimal emission control is modest.

Danish e-purse to end by 2005

The Danish payments body PBS Danmønt has said in a statement that its national e-purse scheme, Danmønt, will be phased out over the next year and a half. According to PBS, the Danmønt cash card was never embraced by the Danes as a preferred way of making small payments.     

M-commerce payment war hots up

Working Digital Money into a Cash Economy: The Collaborative Work of Loan Payment

This paper examines how different forms of money, specifically digital versus cash, impact on the work of an organisation and its customers. In doing so it contributes to the body of literature exploring how the social meanings of money impact on practice. We describe the findings of an ethnographic study examining loan collection workflows, where bank loans given to auto-rickshaw drivers to purchase their auto-rickshaw are overseen and managed by an intermediary. We found that making the mobile money service usable for the drivers took considerable work and was largely achieved because it was embedded in the wider, trusted, loan payment ecosystem. Although Airtel Money promises anytime, anywhere payments, payment remains time and place bound for the drivers. It is tempting to take a transactional approach to payments, and indeed we initially approached the problem of enabling frequent payments as one of payment mechanism. However, in practice payments are embedded in sets of social relations and a socio-technical ecosystem. It takes considerable collaborative work, and a fair amount of flexibility, to enable these financially vulnerable drivers to pay off their loans, and reducing the issue to one of payment mechanism alone does not tell the full story.
