Electronic Payment Systems: Issues of User Acceptans

Electronic commerce and electronic business greatly need new payment systems that will support their further development. This paper discusses issues of user acceptance of electronic payment systems by mass customers and presents results of a user survey on conventional and ele ctronic payment systems that was conducted with the purpose to discover user attitudes towards their chara cteristic properties. The paper presents issues of users acceptance and guiding principles on design of electronic pay- ment systems with high level of user acceptance, which can be a key point in under- standing directions for further development of electronic payment sys tems.

A continuum of governance regimes: A new perspective on co-management in irrigation systems

Over the past, natural resources have been managed to a large part by the state. However, local communities increasingly account for a substantial share of management as well. Approximately 76% of the world’s irrigated area (277 million hectares, 40% of the world’s food production), is managed by local Water User Associations (Garces-Restrepo et al., 2007). Since state-governance did not always met expectations in the 1960 and 1970s (Acheson, 2006), many countries increased the involvement of local resource users in the management process (see Garces-Restrepo et al., 2007 for irrigation). This development led to a variety of different forms of collaboration between governments and communities. Indeed, despite the conceptual distinction, in practice there is considerable overlap between state and community-based governance and a wide diversity of experiences (Meinzen-Dick, 2014). Different ideas have been used to coin these experiences, including joint management, community-based management (Gruber, 2008), (adaptive) collaborative management, and, most prominently co-management (Armitage et al., 2009).

DISTRIBUTED SYSTEMS PRINCIPLES AND PARADIGMS

Q: An alternative definition for a distributed system is that of a collection of independent computers providing the view of being a single system, that is, it is completely hidden from users that there even multiple computers. Give an example where this view would come in very handy. A: What immediately comes to mind is parallel computing. If one could design programs that run without any serious modifications on distributed systems that appear to be the same as nondistributed systems, life would be so much easier. Achieving a single-system view is by now considered virtually impossible when performance is in play. Q: What is the role of middleware in a distributed system? A: To enhance the distribution transparency that is missing in network operating systems. In other words, middleware aims at improving the single-system view that a distributed system should have. Q: Many networked systems are organized in terms of a back office and a front office. How does organizations match with the coherent view we demand for a distributed system? A: A mistake easily made is to assume that a distributed system as operating in an organization, should be spread across the entire organization. In practice, we see distributed systems being installed along the way that an organization is split up. In this sense, we could have a distributed system supporting backoffice procedures and processes, as well as a separate front-office system. Of course, the two may be coupled, but there is no reason for letting this coupling be fully transparent.

Communication Facilities for Distributed Transaction-Processing Systems

Distributed transaction-processing systems must manage such functions as concurrency, recovery, and replication. One way to improve their efficiency and reliability is to increase software modularity, which means the separate components should execute in separate address spaces to permit hardware-enforced separation. This structure offers advantages but demands efficient interprocess communication (IPC) services. In our research at Purdue University, we are investigating mechanisms and paradigms for efficient communication support in conventional architectures, such as virtual-memory, single-processor machines with no special IPC hardware support. (Some mainframes have hardware assistance where more than one address space can be accessed at the same time.) We are studying communication designs in the context of the Raid system, a robust and adaptable distributed database system for transaction processing.’ Raid has been developed at Purdue on Sun workstations under the Unix operating Communication svstem in a local area network. software is critical in distributed computing systems. This research identifies efficient mechanisms and paradigms for distributed transaction processing in a replicated database environment. In Raid, each major logical component is implemented as a server, which is a process in a separate address space. Servers interact with other processes through a high-level communication subsystem. Currently, Raid has six servers for transaction management: the user interface (UI). the action driver (AD), the access manager (AM), the atomicity controller (AC), the concurrency controller (CC), and the replication controller (RC). High-level name service is provided by a separate server, the oracle.

CLASSICAL AND MODERN CONTROL SYSTEMS OF SELF-EXCITED INDUCTION GENERATOR

The main objective of this paper is to design a computerbased controller for the capacitor self-excited induction generator (CSEIG) using terminal capacitors. The generator is assumed to be a power source in an isolated system. System voltage regulation will be the major requirement of the designed controller. This will be achieved by regulating the generator exciting capacitance in response to changes in system operating conditions. An implementation of three types of controllers; PI, PID and Fuzzy Logic Controllers (FLC) is developed. The influence of these control methods on the performance characteristics of the system under consideration is examined. Also, a computer simulation using the MATLAB package is designed to assist the experimental decision for the best control action. The obtained simulation and implementation results are investigated and discussed.

INTEGRATED INFORMATION SYSTEMS AND INTERORGANIZATIONAL PERFORMANCE THE ROLE OF MANAGEMENT ACCOUNTING SYSTEMS DESIGN

The interorganizational environment faced by business organizations presents unique challenges for management accounting and control. Past management accounting research has shown interest in such collaborations because despite their benefits, such relationships pose significant issues of coordination and control. As information and communication systems supplement management control systems in their support of decision facilitation and decision influencing, examining the design of management accounting systems (MASs) in the management of interorganizational relationships and assessing how it affects the attainment of interorganizational exchange partner performance objectives is important. In this chapter, I extend past accounting research to examine the complementary nature of decision-facilitation and decisioninfluencing objectives of MAS design as enabled by the use of integrated information systems in interorganizational settings. The economic theory of complementarity is employed to examine synergistic effects of complementary MAS objectives. A field survey is used to examine hypothesized relationships, and data were obtained from 116 organizations involved in strategic alliance activity. This chapter reports findings that support the view that the degree of complementarity in decisionfacilitation and decision-influencing objectives assists in the development of capabilities that enhance performance in the interorganizational relationship. The study blends theory in the areas of strategy, information systems, and management accounting and extends management accounting research in the context of IT-enabled interorganizational relationships.
