what do others reactions to news on Internet Portal sites tell us effects of presentation format and readers need for cognition on reality perception
Communication Research, 2010Co-Authors: Yoon Jae JangAbstract:The present experiment investigated if and how other readers’ reactions to news on Internet Portal sites affect individuals’ perceptions of public opinion, assessments of media influence, and their personal opinion. In so doing, others’ responses were shown as either individual comments or aggregate approval ratings of the article, and the individual’s need for cognition (NFC) was considered as a potential moderator of their relative effects. High NFC individuals relied more on the approval ratings than individual postings in estimating media influence on general public, but low NFC individuals’ presumption about media influence remained unaltered, regardless of how others’ reactions were presented. However, exposure to dissenting comments led both high and low NFC individuals to perceive the public opinion as more discrepant from the news position, with no corresponding effect for approval ratings. Others’ comments significantly affected participants’ personal opinion, but only for those less prone to en...

ICCS - A Workflow Application for Parallel Processing of Big Data from an Internet Portal
Procedia Computer Science, 2020Co-Authors: Pawel CzarnulAbstract:Abstract The paper presents a workflow application for efficient parallel processing of data downloaded from an Internet Portal. The workflow partitions input files into subdirectories which are further split for parallel processing by services installed on distinct computer nodes. This way, analysis of the first ready sub-directories can start fast and is handled by services implemented as parallel multithreaded applications using multiple cores of modern CPUs. The goal is to assess achievable speed-ups and determine which factors influence scalability and to what degree. Data processing services were implemented for assessment of context (positive or negative) in which the given keyword appears in a document. The testbed application used these services to determine how a particular brand was recognized by either authors of articles or readers in comments in a specific Internet Portal focused on new technologies. Obtained execution times as well as speed-ups are presented for data sets of various sizes along with discussion on how factors such as load imbalance and memory/disk bottlenecks limit performance.

Internet Portal use in an academic multiple sclerosis center
Journal of the American Medical Informatics Association, 2012Co-Authors: Scott A Nielsen, John Halamka, Philip R KinkelAbstract:Objective To evaluate the use of a secure Internet Portal in an academic Multiple Sclerosis (MS) Center. Materials and methods Retrospective case–control chart review of 240 patients during the years 2008 and 2009. Patient demographic and clinical information was extracted from our online medical records, and Portal use metrics were provided by Information Systems. Descriptive statistics were utilized to explore characteristics of Portal users, how the Portal is used, and what associations exist between medical resource utilization and active Portal use. Logistic regression identified independent patient predictors and barriers to Portal use. Results Portal users tended to be young professionals with minimal physical disability. The most frequently used Portal feature was secure patient–physician messaging. Message content largely consisted of requests for medications or refills in addition to self-reported side effects. Independent predictors and barriers of Portal use include the number of medications prescribed by our staff (OR 1.69, p<0.0001), Caucasian ethnicity (OR 5.04, p=0.007), arm and hand disability (OR 0.23, p=0.01), and impaired vision (OR 0.31, p=0.01). Discussion MS patients use the Internet in a greater proportion than the general US population, yet physical disability limits their access. Technological adaptations such as voice-activated commands and easy font-size adjustment may help patients overcome these barriers. Conclusion Future research should explore the influence of Portal technology on healthcare resource utilization and cost. Additional emedicine applications could be linked to the patient Portal for disease monitoring and prospective investigation.

Encyclopedia of Portal Technologies and Applications - A Study of a Wine Industry Internet Portal
Encyclopedia of Portal Technologies and Applications, 2020Co-Authors: Carmine SellittoAbstract:A simple definition of a Portal sees it as a special Internet (or intranet) Web site designed to act as a gateway to give convenient access to other related sites (Davison, Burgess, & Tatnall, 2003). Moreover, Portals can be grouped or classified based on genre, with a diverse number of different types of Portal types being based on alliances, geographic regions, special interest, and communities. Regional Portals that are of particular interest in this article tend to be a special type of community Portal centred on a specific locality. As such, they have a utility in providing various advantages for the participants, allowing them to feel as if they are part of, and contribute to, the local regional community. Moreover, there are significant benefits that Portal participation provides in allowing firms to interact with other local businesses, allowing not only physical products/services to be transacted, but also in fermenting new business relationships (Sellitto & Burgess 2005). Indeed, regional Portal participation contributes to the goodwill factor that manifests at the local business level and invariably, also at the social level throughout the regional community. This article introduces some background on Portals, and provides an illustration of how a real-world regional wine cluster adopted an Internet Portal to strengthen and benefit their regional partnerships. Arguably, the research is one of the few published works on industry clusters and their association to Internet Portals.

a government funded Internet Portal as a promoter of regional cluster relationships a case study from the australian wine industry
Environment and Planning C-government and Policy, 2005Co-Authors: Carmine Sellitto, Stephen BurgessAbstract:This paper reports on a study that examined the relationship between a small winery cluster and the implementation of a government-sponsored Internet Portal—the WinesOfGippsland.com site. Literature relating to industry clusters and Internet Portals is examined to identify the beneficial features associated with Portals and clusters. The paper makes a link between Portal benefits and those typically associated with industry clusters, with the subsequent implications for policy. The study found that the winery business experience after Portal implementation enhanced relationships between small wine producers, resulting in outcomes that included resource sharing, informal knowledge exchanges, and innovative practices that resulted in new product development. Indeed, these types of benefits tend also to be reported in successful clusters. Moreover, the authors argue that government policy may achieve more favourable outcomes in promoting e-commerce and Internet adoption in regional areas by identifying established business clusters (more so than ad hoc related groups) that can use their already established relationships quickly and appropriately to leverage the business benefits associated with new technologies.

the brustkrebs studien de website for breast cancer patients user acceptance of a german Internet Portal offering information on the disease and treatment options and a clinical trials matching service
BMC Cancer, 2010Co-Authors: Markus Wallwiener, Christian W Wallwiener, Sara Y Brucker, A Hartkopf, T Fehm, Julia K KansyAbstract:Background The Internet Portal http://www.brustkrebs-studien.de (BKS) was launched in 2000 by the German Society of Senology (DGS) and the Baden-Wurttemberg Institute for Women's Health (IFG) to provide expert-written information on breast cancer online and to encourage and facilitate the participation of breast cancer patients in clinical trials. We describe the development of BKS and its applications, and report on website statistics and user acceptance.
