    The Web portals business model has spread rapidly over the last few years. Despite this, there have been very few scholarly findings about which services and characteristics make a Web site a portal and which dimensions determine the customers’ evaluation of the portal’s quality. Taking the example of financial portals, the authors develop a theoretical framework of the Web portal quality construct by determining the number and nature of corresponding dimensions, which are: security and trust, basic services quality, cross-buying services quality, added values, transaction support and relationship quality. To measure the six portal quality dimensions, multi item measurement scales are developed and validated.Construct Validation, Customer Retention, E-Banking, E- Loyalty, Service Quality, Web Portals

    Information Systems Research Themes: A Seventeen-year Data-driven Temporal Analysis

    Extending the research on our discipline’s identity, we examine how the major research themes have evolved in four top IS journals: Management Information Systems Quarterly (MISQ), Information Systems Research (ISR), Journal of the Association for Information Systems (JAIS), and Journal of Management Information Systems (JMIS). By doing so, we answer Palvia, Daneshvar Kakhki, Ghoshal, Uppala, and Wang’s (2015) call to provide continuous updates to the research trends in IS due to the discipline’s dynamism. Second, building on Sidorov, Evangelopoulos, Valacich, and Ramakrishnan (2008) we examine temporal trends in prominent research streams over the last 17 years. We show that, as IS research evolves over time, certain themes appear to endure the test of time, while others peak and trough. More importantly, our analysis identifies new emergent themes that have begun to gain prominence in IS research community. Further, we break down our findings by journal and show the type of content that they may desire most. Our findings also allow the IS research community to discern the specific contributions and roles of our premier journals in the evolution of research themes over time

    Tracking the Donor Dollar: A Critical Examination of NGO Impact

    Get PDF
    Non-governmental organizations (NGOs) comprise the backbone of civilization. Whether intended or not, governments fail to improve social situations, financial standings, and spirituality comprehensively. NGOs attempt to cover these areas. From Angola to Zambia, countless NGOs exist around the world; however, many fail due to a misplaced focus internally on the annual donations received rather than externally on the disenfranchised. Additionally, even if NGOs manage to stay afloat, they will need help procuring funds and then distributing those resources with the most effective impact for the impoverished. The honors thesis proposed will attempt to determine more effective impact measurements for NGOs, examining the context of varying financial obtainment strategies, resource allocation decisions, qualitative and quantitative evaluation mechanisms, and critical accountability metrics

    Social Networks, Personalized Advertising, and Privacy Controls

    This paper investigates how internet users' perception of control over their personal information affects how likely they are to click on online advertising. The paper uses data from a randomized field experiment that examined the relative effectiveness of personalizing ad copy to mesh with existing personal information on a social networking website. The website gave users more control over their personally identifiable information in the middle of the field test. The website did not change how advertisers used anonymous data to target ads. After this policy change, users were twice as likely to click on personalized ads. There was no comparable change in the effectiveness of ads that did not signal that they used private information when targeting. The increase in effectiveness was larger for ads that used less commonly available private information to personalize their message. This suggests that giving users the perception of more control over their private information can be an effective strategy for advertising-supported websites

    Valuing the Past: The Constitution of the Antiques Market in Russia

    Get PDF
    Valuation and assessment of antiques are in the focus of the thesis: the symbolic and narrative character of these objects of the past makes them a special case among other singular goods. Their value developed over time into a number of orders of worth (Boltanski and Thevenot 2006) where antiques are conceptualized as historical, cultural, aesthetic, sentimental, and financial assets. As objects of art, antiques are not standardized: in some cases they were produced as unique and single objects, in other cases the process for becoming a valued antique varied. Moreover, many antique objects have their own histories relaying evidence of the unique circumstances under which they produced, exchanged, possessed, lost and found again. As a result there are almost no antiques that can be assessed using one given set of criteria. In market terms such characteristics translate into high uncertainty of quality for these goods. In light of this, the central question of the thesis is: How are antiques valued given the uncertainty of product quality and the context of unstable macro-structures in Russia? The main goal is to find market devices that help to solve this problem. An inquiry into the possible devices is presented in the empirical study of the antiques market in Russia as well as in research on the history and nature of unstable macro-structures that influence valuation. The process of valuing antiques that involves appraisal and attribution is an ambiguous one: market actors need specialized knowledge in the field of decorative art and art history in order to make the correct judgments. Discontinuities in historical records mean that this specialized knowledge is often open to debate. What is more, specialized knowledge may be inaccessible to some market actors, or be too difficult for them to grasp in order to be able to make proper use of it. The past has to be taken into account, but it is also inherently uncertain. Thus actors in the antiques market have to cope with more than the traditional problem of uncertainty regarding the future: the discoveries of new artifacts, or just historical facts, can significantly influence the valuation of objects

    Engaging end-user driven recommender systems: personalization through web augmentation

    Get PDF
    In the past decades recommender systems have become a powerful tool to improve personalization on the Web. Yet, many popular websites lack such functionality, its implementation usually requires certain technical skills, and, above all, its introduction is beyond the scope and control of end-users. To alleviate these problems, this paper presents a novel tool to empower end-users without programming skills, without any involvement of website providers, to embed personalized recommendations of items into arbitrary websites on client-side. For this we have developed a generic meta-model to capture recommender system configuration parameters in general as well as in a web augmentation context. Thereupon, we have implemented a wizard in the form of an easy-to-use browser plug-in, allowing the generation of so-called user scripts, which are executed in the browser to engage collaborative filtering functionality from a provided external rest service. We discuss functionality and limitations of the approach, and in a study with end-users we assess the usability and show its suitability for combining recommender systems with web augmentation techniques, aiming to empower end-users to implement controllable recommender applications for a more personalized browsing experience.Fil: Wischenbart, Martin.
