However, surprisingly little is known about how the communication activity of their users develops and changes over time. A longitudinal study bears the potential to better elaborate the enabling and inhibiting factors of the users' communication activity in OCs. To explore these phenomena, we aim to develop a conceptual framework that serves as a foundation to guide an explorative data analysis of real OCs. The notions of common ground, information overload, interactivity and social loafing will be used to explain the communication activity of the users in online communities. The empirically explored framework will help organizations to support the development of OCs and utilize them in an economically successful way. Based on a literature review we develop a first conceptual framework. Then, we apply it to describe the development of the communication activity and its determinants in an OC hosted by a German financial service provider. The study examines over 33,000 participants and 1.03 million messages over a period of 3 years. We find a strong effect of external factors on the size of this OC. The size of the OC shows no direct influence on the communication activity of the users. But, in reaction to the increasing information load, communication strategies change and herewith influence the communication activity. The heterogeneity of the users' activity is growing over time and a small minority of users writes more and more of the postings.","PeriodicalId":159242,"journal":{"name":"36th Annual Hawaii International Conference on System Sciences, 2003.

Wheeler","doi":"10.1109/HICSS.2003.1174566","DOIUrl":"https://doi.org/10.1109/HICSS.2003.1174566","url":null,"abstract":"Information Systems researchers have recently directed their attention to Net-Enabled Organizations (NEOs) (See 2002 volumes 2 & 3 of Information Systems Research). NEOs can execute transactions, rapidly exchange information, and innovate through new business processes and at an unprecedented pace. Deeper theorizing and measuring is needed to fully understand the deeper means through which NEOs operate for business advantage. This year marks the first time for the Measuring and Theorizing about Net-Enabled Organizations Minitrack. The three papers presented here demonstrate the wide domain for this emerging area of IS research. Williams digs deeper into Wheeler’ Choosing Capability in NEBIC Theory. His paper, “Identifying the Organizational Routines in NEBIC Theory’s Choosing Capability” draws on other theories of organizational routines and innovation to focus on four explicit routines in how organizations choose emerging or enabling technologies. Benslimane, Plaisent, and Bernard’s paper, “Applying the Task-Technology Fit Model to WWWbased Procurement: Conceptualization and Measurement,” assesses the fit of we-based technologies from the perspective of a corporate buyer. Lubbes draws on research in South Africa as he addresses the “Alignment of Internet Commercial Operations with Organisational Operations.” His work focuses on how alignment is essential for value creation via new digital networks. In sum, these three papers represent an important first steps in better theorizing and measuring of NetEnabled Organizations. Future mini-track sessions and journal articles provide opportunities for further developing both theory and measures.","PeriodicalId":159242,"journal":{"name":"36th Annual Hawaii International Conference on System Sciences, 2003.

Downs","doi":"10.1109/HICSS.2003.1174283","DOIUrl":"https://doi.org/10.1109/HICSS.2003.1174283","url":null,"abstract":"The theme of this minitrack is how people use robots or computer systems to facilitate their performance. We sought papers that concern problems in augmented cognition and human-robot interaction. A goal of augmented cognition is to reduce the complexity of tasks. Suggested ways of accomplishing this goal include utilizing technology to adapt either the task or the way the task is represented. We encouraged papers related to all facets of augmented cognition and human-robot interaction and are pleased to present papers that not only describe systems designed to augment cognition but also provide empirical studies, field studies and case studies that evaluate these systems. Scholtz introduces the human-robot interaction portion of this minitrack by describing the rationale behind the theory and evaluation of these interactions. In describing their version of embedded interfaces for human-robot interaction, Daly, Cho, Martin and Payton show how they use techniques from augmented reality to communicate information from large numbers of small scale robots operating as a coordinated swarm. In their paper on human-robot interaction for intelligent assisted viewing during teleoperation, McKee and Brooks report finding a simpler reactive algorithm to replace their visual acts algorithm. Experimental evidence showed the newer algorithm performed as well as the previous algorithm as well as encouraging the operator to be more aware of depth information. Nicolescu and Mataric linked perception and action in a unique architecture for representation of robots' behaviors. Kawamura, Nilas, Muguruma and Johnson describe efforts to develop an adaptive graphical user interface for mixed-initiative interaction between a human and robot. In a practical application, Bruemmer, Marble, Dudenhoeffer, Anderson, and McKay present a case study that examines the human-robot dynamic of a teleoperated task. They outline a mixed-initiative command and control architecture for hazardous environments. Biagioni and Sasaki propose and analyze efficient wireless sensor placement to satisfy communication and data collection requirements. Several of the papers employ either user models or physiological measurements to assess skills or mental processes. For example, Brezillon, focuses on","PeriodicalId":159242,"journal":{"name":"36th Annual Hawaii International Conference on System Sciences, 2003.

Even simple arithmetic operations over a set of integers partitioned over a network require sophisticated algorithms. As apart of our earlier work, we have developed a secure protocol for computing dot products of two vectors. In this paper, we present a secure protocol for Yao's millionaires' problem. In this problem, each of the two participating parties have a number and the objective is to determine whose number is larger without disclosing any information about the numbers. This problem has direct applications in on-line bidding and auctions. Furthermore, combined with a secure dot-product, a solution to this secure multiparty computation provides necessary building blocks for such basic operations as frequent item-set generation in association rule mining. Although an asymptotically optimal solution for the secure multiparty computation of the 'less-or-equal' predicate exists in literature, this protocol is not suited for practical applications. Here, we present a protocol which has a much simpler structure and is more efficient for numbers in ranges practically encountered in typical e-commerce applications. Furthermore, advances in cryptanalysis and the subsequent increase in key lengths for public-key cryptographic systems accentuate the advantage of the proposed protocol. We present experimental evidence demonstrating the efficiency of the proposed protocol both in terms of time and communication overhead.","PeriodicalId":159242,"journal":{"name":"36th Annual Hawaii International Conference on System Sciences, 2003.

The results of this analysis unveil that such needs can either be ritualized or instrumental. Furthermore, the uses and gratifications theory was applied in order to formulate a questionnaire to which 68 current users of digital TV responded. The results of this empirical study reveal that applications most suitable for the interactive television environment should aim at the gratification of ritualized needs, such as entertainment and communication. Therefore, applications that appeal to instrumental needs, such as information and transactions should be included as add-ons to entertainment and communication services. Finally, the implications of this analysis for the design of interactive television applications are exploited.","PeriodicalId":159242,"journal":{"name":"36th Annual Hawaii International Conference on System Sciences, 2003.

Before theoretical models can be built and before meaningful empirical research can be performed, a careful process of identifying the appropriate research questions and problems must be undertaken. This is the current state of research regarding the relatively new area of the continuous audit (CA). Though the concepts of CA have been around for almost a decade, and recent advances have made the technologies both widely available and very affordable, firms have yet to make significant steps toward implementation. Thus, there is a need for exploratory surveys of key audit personnel in charge of providing assurance services for major clients to bring to light the issues regarding technology, people, and processes with which auditors and their audit clients are wrestling. This paper discusses the results of a survey of the U.S. assurance partners of a Big 4 accounting firm. The objective of the survey was to get the partners' perceptions and thoughts on the viability of the continuous auditing, the current state of the CA in the audit environment, the impact that CA implementation might have, and the various roadblocks to CA implementation. In addition, various demographic data was collected. So that the open-ended questions of the survey instrument could be systematically categorized and analyzed, and to minimize interpretation bias, QSR NUD-IST/spl copy/ (nonumerical unstructured data-indexing, searching, and theorizing) version 4 software was used to code responses and capture emergent themes. The purpose of this paper is to present the results of this survey, revealing the current state of the CA and the hurdles to overcome in its implementation.","PeriodicalId":159242,"journal":{"name":"36th Annual Hawaii International Conference on System Sciences, 2003.

Schumann","doi":"10.1109/HICSS.2003.1174579","DOIUrl":"https://doi.org/10.1109/HICSS.2003.1174579","url":null,"abstract":"Due to the widespread appearance of filesharing systems like Napster, the peer-to-peer concept has recently become well known. So far, these file-sharing systems have been used for the exchange of digital goods. We recommend a concept, based on that of the file-sharing system, for a decentralized electronic marketplace that focuses on the exchange of physical goods. In contrast to file-sharing systems, the decentralized electronic marketplace would emphasize the decentralized management of transactions instead of the delivery of the goods themselves, since it would be impossible to distribute the traded goods via digital networks. Such a concept can be imagined as a \"Napster for transactions \", the difference being that this peer-to-peer system would be used for files that contain parts of a transaction e.g. a demand document, a supply document, or an invoice document instead of for the exchange of audio and video files. In contrast to conventional file-sharing systems, these transaction elements are dependent on one another, i.e. they need to be combined to complete a transaction. It is the role of the peer-to-peer infrastructure to manage the flow of the transaction elements in order to complete a transaction. Such an infrastructure would allow the management of transactions without the presence of a middleman, leading to lower prices of the traded goods. What follows is a description of the conceptual and technical details of a decentralized electronic marketplace based on peer-to-peer technology and a discussion examining the extent to which the functions of a conventional intermediary can be replaced by a decentralized peer-to-peer-infrastructure.","PeriodicalId":159242,"journal":{"name":"36th Annual Hawaii International Conference on System Sciences, 2003.

The authors propose two types of institutional trust (a) third-party institution-based trust, which deals with intermediary driven structures, such as those in online B2B marketplaces, and (b) bilateral institutionalized trust, which deals with dyadic interorganizational processes, standards, and norms. We examine how institutional trust develops through their underlying dimensions (i) structural assurances, (ii) facilitating conditions, and (in) situational normality to engender trust and influence relationship continuity. This study focuses on the time-dependent nature of institutional trust from the exploratory to the maturity phase by describing (a) the role of bilateral relative to third-party institutional trust on buyer-supplier trust, and (b) the transition of the three underlying institutional dimensions on trust over the relationship's life cycle. This research has implications for (I) the longitudinal role of institutional trust in online relationship building, (2) the design of trust-building mechanisms in online B2B marketplaces, (3) the safe and cost-effective building of online interorganizational relationships, and (4) the literature on initial trust formation.","PeriodicalId":159242,"journal":{"name":"36th Annual Hawaii International Conference on System Sciences, 2003.
