Psychological Contract Violation in Online Marketplaces: Antecedents, Consequences, and Moderating Role This study examines the nature and role of psychological contract violation (PCV) in online marketplaces, a critical factor that has been largely overlooked by previous research. Applied to buyer-seller relationships, PCV is defined as a buyer’s perception of having being treated wrongly regarding the terms of an exchange agreement with an individual seller. PCV with individual sellers is proposed as a formative first-order construct driven by the occurrence of fraud, product misrepresentation, contract default, delivery delay, and failure to follow product guarantees and payment policies. PCV with an individual seller is proposed to prompt a generalized perception of PCV with the entire community of sellers in a marketplace. PCV with the community of sellers is hypothesized to negatively affect buyer transaction behavior in a marketplace by directly impacting transaction intentions, price premiums, trust, perceived risk, and the

Arr standardized business processes less risky to outsource? Despite the importance of botlz areas, neither the OU~SOIIJ~C~~ ~ nor standardization literatzrre has so fir offired tr conclusive picture of the value of standards to outsourcing. We aitlr to provide an exploralory.fist step by suggesting that process strrndrrrds have a positive impact on bilsiness process outsourcing (BPO) risk. theoretical! ^ drawing from perceived risk theory and the theory of reasoned action we develop a model of BPO risk and empirically show that indeed risk perception is higher for less standardized processes. C'sing data from 126 GerAmaiz banks, it turns out that financial and performance risks sign@cant49 d&er between high- and low-stnndar.dized processes and are consistently higher.for lowsta~ldclrdized processes. While this work is very exploratoty and the,findings are quite preliin~nczrv, they are very encozlraging as they indicate promising jlrther research into the value of standad for business processes and ozltsourcing. 1.

of Business In this paper, we apply the theory of task technology fit to mobile technology, focusing specifi−cally on the role of user mobility. We describe the results of an empirical study of 216 business users of mobile devices that included various smart phones, personal digital assistants (PDAs), and laptop computers. Our findings suggest that (1) the relationship between task difficulty and functional requirements of the mobile devices is stronger for highly mobile users than for less mobile users; (2) user mobility is associated with increased user−perceived importance of a number of non−functional features; and (3) for a number of functions and features, highly mobile users indicated a stronger relationship between task−technology fit, and overall evaluation of the technology. We conclude that user mobility needs to be taken into account when applying the theory of task−technology fit to mobile information systems. In addition, our study provides spe−cific insights about the information system requirements of an increasingly mobile workforce.

with all my love The advent of the Internet and the digitization of music has resulted in a multitude of new challenges and opportunities for the recording industry. So far, sales of digital downloadable music have not compensated for the decrease in CD sales throughout the twentyfirst century. To attract new customers and successfully compete with file-sharing networks, commercial online music services need to meet customer expectations by delivering what they value. Therefore, to increase the understanding of prospective customers, the purpose of this thesis was to explore and describe customer value and target groups within the online music market. Data were collected through a survey of Swedish consumers between 16 and 60 years old. Customer-perceived value of downloadable music, in terms of expected value for money, was found to be quite low. Value could, however, be increased by improving the most important benefits. In addition to fundamental functions, such as

{jahner; leimeister; knebel; krcmar} @ in.tum.de Purpose: Drawing from literature on innovation, strategy and culture the objective of this study is to explore the role of perceived potentials and perceived strategic importance on CIOs ’ perspective on RFID technology in two different cultural settings. Methodology: Based on survey responses from 463 German and 157 Italian IT decision makers we analyzed the data with PLS structural equation modeling. Findings: We show that perceived potentials of RFID influence the perceived strategic importance which positively influences CIOs ’ intention to invest in RFID. The composition of perceived potentials affecting the strategic importance of RFID differs significantly in both cultures. In Germany, potentials attributed to RFID are improving quality, automating manpower, reducing counterfeits, and improving customer-service. Italian CIOs value reducing stock inconsistencies, optimizing stock keeping, and improving customerservice as RFID potentials. Regardless of culture, findings show that company size hardly has impact on perceived strategic importance. Originality/value: This research shows on a large empirical basis cultural differences in the perception of RFID in two countries using PLS.

After years of stagnancy, PLS path modeling has recently attracted renewed interest from applied researchers in marketing. At the same time, the availability of software alternatives to Lohmöller’s LVPLS package has considerably increased (PLS-Graph, PLS-GUI, SPAD-PLS, SmartPLS). To help the user to make an informed decision, the existing programs are reviewed; their strengths and weaknesses are identified. Furthermore, analyzing simulated data reveals that the signs of weights/factor loadings and path coefficients can vary considerably across the different programs. Thus, applied researchers should treat the interpretation of their results with caution. Compared to programs for analysis of covariance structure models (LISREL approach), PLS path modeling software is on equal footing regarding ease of use, but clearly lags behind in terms of methodological capabilities.

The nature of IS use and its impacts in everyday life settings are not yet well understood. Drawing on quality of life theory and evidence from the IS acceptance and IS impacts research, this study conceptualizes the relationship between IS use and quality of life as a process that involves vertical and horizontal spillover effects. We empirically investigate this relationship in the context of basic IT use among socio-economically disadvantaged individuals. The research participants received their initial basic IT skill training from community technology centers. The context of our study is the Thai community technology centers supported by Microsoft Unlimited Potential grants. The results strongly support that there are vertical spillover and horizontal spillover mechanisms that relate IS use to domain-specific quality of life and overall quality of life. Implications for research and practice are discussed.

Our work is concerned with an enriched perspective of what constitutes developer contribution in software infrastructures supporting incremental development and distributed software projects. We use the term “contribution” to express the combination of all the actions a developer has performed during the development process and propose a model for calculating this individually for developers participating in a software project. Our approach departs from the traditional practice of only measuring the contribution to the final outcome (the code) and puts emphasis additionally on other activities that do not directly affect the product itself but are essential to the development process.We use the Open Source Software (OSS) context to take advantage of the public availability of data in software repositories. In this paper, we present our method of calculation and its system implementation and we apply our measurements on various projects from the gnome ecosystem.
