Therefore, ideas and innovations generated by members of a virtual community can be analyzed and used in order to enhance the quality of firm's products and services. However, evaluating economic consequences associated with the set-up, operation, and maintenance of virtual communities on a quantitative basis has widely been neglected in social network research. Thus, the objective of this paper is therefore to develop a measurement framework for the financial performance, including revenues and expenditures of a virtual community platform reflecting specific economic conditions relevant in a certain situation. The measurement framework is then applied to a real life example of the Berlin Stock Exchange, in Germany.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126794326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By addressing such specific issues in the software market as network effects, quality uncertainty, upgrade compatibility, and the vendor's ability to commit to future prices in a dynamic environment, we demonstrate how a software vendor can manage the trade-offs of perpetual licensing and subscription to optimize profit, as well as the corresponding welfare effect on consumers. Though the subscription model helps the vendor lock in consumers so as to increase profit when there is a great uncertainty associated with the next version software, it destroys the path dependence in creating network externalities.Therefore, when the network effect is sufficiently large, it is more profitable for a software vendor to provide both perpetual licensing and subscription.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123244296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microfinance providers, both non-profit microfinance institutions (MFIs) and for-profit banks, provide financial services to the poor, and are critical for economic development in developing nations. As the industry matures, MFIs face a competitive environment, forcing them to balance the goals of outreach and sustainability. ICT may be the instigator of this new environment and the potential solution to MFI survivability. We propose research directions on the role and impact of ICT in the microfinance industry, using a microfinance technology and stakeholder ecosystem framework. This research is at the intersection of inquiry on ICT for development and the digital divide, the impact of microfinance, and the use of ICT in the financial services industry. We discuss the role and impact of ICT at the customer, the microfinance institution, donor, and industry levels.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"276 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123323348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis presented in this paper uses an optimal power flow (OPF) model in a Monte Carlo Simulation (MCS) framework to estimate the cost impacts from the uncertainty in windfarm output. Using various regional load levels, and assumptions on the costs for providing balancing energy, the results from the OPF and MCS show that wind power forecast uncertainty for the test system can increase production cost up to 350 times, though for most cases the forecast uncertainty does not introduce significant changes from the base cases. The real and reactive power losses are shown to be higher for scenarios with low wind-high load and high wind-low load as compared to the moderate wind-load cases.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123340725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on a case study in a radiology practice, we compare the operational and economic differences between a system that uses barcode technology and periodic review, and one that uses RFID technology and continuous review. While the first switch from barcode to RFID is a technology improvement providing automatic counting, the second switch from periodic to continuous review is a process innovation. We measure the value of automatic counting, process innovation, and the total of the two, (the value of RFID).

Yet conceptions from diverse fields reveal no universally accepted understanding of this term. An examination of historical developments leading up to the Internet era reveals mutual dependence between technical infrastructures and diverse social arrangements including industry, regulatory, and market structures. A set of criteria for the definition of digital convergence (and divergence) is formulated. These provide a working definition that reveals the essential, pervasive and interactive reconfiguration of modern society's technical and social infrastructures due to digitization. A layer-based model is presented as one possible way of breaking up an increasingly interconnected socio-technical world into separate domains that allow meaningful study. We call for action to address the paucity of recent Information Systems (IS) research into the infrastructures that provide the foundations upon which all modern information systems build.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121318855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are few studies that investigate how organizations adopt assemblages of heterogeneous technologies across contexts. Recognizing that it is only when engaged by social actors that actual consequences of integrated technologies will occur, this paper explores how the increasing availability of information in multiple social and physical contexts may impact organizational practice. An interpretive multiple-case study of road transport organizations combining heterogeneous technologies is analyzed using a practice lens. The analysis of enactments of implemented technologies revealed both intended and unintended outcomes. Reflecting on the contradictory outcomes, the paper makes two contributions: 1) it conceptualizes organizational implications of the integration of embedded, mobile, and stationary technologies; 2) it extends the current understanding of how to study the interplay between agency, structure, and technology in sociotechnical assemblages.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122280922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Focus groups' results were first used to develop a survey; then a total of 455 surveys from both countries collected perceptions on four e-government services. Multi-group path analysis assessed the associations and differences between trust and service utilization. Results indicate the U.S. shows higher trust and utilization compared to Mexico. The two countries differ particularly in the impact of perceptions of the government's benevolence and competence on e-government service utilization Perceptions about the government's handling of data affects utilization only in the U.S., and the e-medium impacts utilization in both cultures.

The premise of the quip is that CIOs' career paths and tenure (or survivability) in their positions may not the same as those of other C-suite executives: the chief executive officer (CEO), the chief financial officer (CFO) and the chief operating officer (COO). Is this truly the case? What evidence is available to assert that CIOs exhibit shorter job tenure than their C-suite executive colleagues? This research explores three alternate theoretical interpretations that compare and contrast reasons why team-building, the turbulence of the business and organizational environment, and the gender of the executive appear to have different impacts on the tenures of the different categories of executives. Our empirical research takes advantage of a new data set acquired during Spring 2009 from the State of California that provides information on C-suite executives from 223 state agencies. The data consist of 504 observations of executive tenure, including their start and finish dates, and the relevant variables for their organizational, market and technological environments that permit us to assess their survivability. To conduct this exploratory analysis of the empirical regularities of public sector executive tenure, we utilize statistical methods from epidemiology and public health. Our results cast doubt on many of the enduring beliefs about public sector CIOs by showing the relative infrequency of their job changes and by showing that job changes are, unlike for other C-suite executives, more closely tied to instances of environmental turbulence. In all, this exploratory paper suggests a reexamination of the way that public sector CIOs are viewed relative to other C-suite executives.","PeriodicalId":328811,"journal":{"name":"2010 43rd Hawaii International Conference on System Sciences","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115897850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
