However, due to profit-maximizing forces controlling healthcare, the majority of e-based systems are characterized by non-existent or marginal compatibility leading to platformcentricity that is, a large number of individual information platforms incapable of integrated, collaborative functions. While such systems provide excellent service within limited range healthcare operations (such as hospital groups, insurance companies, or local healthcare delivery services), chaos exists at the level of nationwide or international activities. As a result, despite intense efforts, introduction of e-health doctrine has minimal impact on reduction of healthcare costs. Based on their previous work, the authors present the doctrine of network-centric healthcare operations that assures unimpeded flow and dissemination of fully compatible, high quality, and operation-relevant healthcare information and knowledge within the Worldwide Healthcare Information Grid (WHIG). In similarity to network-centric concepts developed and used by the armed forces of several nations, practical implementation of WHIG, consisting of interconnected entry portals, nodes, and telecommunication infrastructure, will result in enhanced administrative efficiency, better resource allocation, higher responsiveness to healthcare crises, and—most importantly—improved delivery of healthcare services worldwide.","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126100135","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}

{"title":"Providing Rating Services and Subscriptions with Web Portal Infrastructures","authors":"Boris A. Galitsky, M. Levene","doi":"10.4018/978-1-59140-989-2.CH141","DOIUrl":"https://doi.org/10.4018/978-1-59140-989-2.CH141","url":null,"abstract":"A Web infrastructure (portals) for providing online rating of services such as financial services, are becoming more popular nowadays. A rating portal providing comparisons between competitive services has the potential of becoming a well-established Web enterprise. For some services, the comparison is performed based on a set of measurable values such as performance and price, for example, when the service involves computer hardware. In such an environment, services can make a rational decision whether they wish to advertise on the portal based on the set of measurable values (compare with Tennenholtz, 1999). However, for some services like banking, brokerage, and other financial services characterised by such parameters as customer support quality, it is impossible to establish an objective set of measurable values. In these cases, the rating portals publish their scores for the competing businesses based on their own private estimation strategy. We believe that evolution of the interactions between the agents being rated and rating agents is an important social process, which is worth examining thorough simulation. In this study, we simulate the plausible interaction between portals and services using a simplified model, and we analyse possible scenarios of how services can influence the portals’ rating system. Our approach is based on a straightforward revenue model for rating portals, where they require the rated services to be paying to these portals in order to obtain a rating. Within this model, we follow the dynamics of how the competing services may influence the portals to improve their respective ratings. Over the last couple of years, the role of paid advertisement placement at Web portals has dramatically increased. Until recently, there were just one or two such advertisements per customer query displayed on keyword search portals. Nowadays, after Google’s IPO, the business model of paid placement has become very popular, and the majority of search engines have designated areas for displaying advertisement slots on their search results Web pages. This number of advertisement placements is expected to be growing even faster, and their order (from top to bottom) may be interpreted by users as a rating by a respective search portal. This is due to the fact that it is hard for end users to access the pricing policy for paid placements at keyword search portals (Sherman 2004). Therefore, possible mechanisms of providing such ratings and their evolution are worth exploring. We conduct the what-if study suggesting a simple model with rational agents for services and portals as possible for a simulation of the subscription model. This model is implemented and analysed in detail in Galitsky and Levene (2005). The resultant behaviour is verified and analysed with respect to the possibility of extracting patterns of rating subscription-based behaviour from real publicly available data. We conclude the article with a discussion of how the pred","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130024358","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}

Carbone","doi":"10.4018/978-1-59140-989-2.CH010","DOIUrl":"https://doi.org/10.4018/978-1-59140-989-2.CH010","url":null,"abstract":"Over the past 30 years the health framework in which doctors and other healthcare professionals practise has changed relatively little in comparison with the enormous changes seen in transport, manufacturing, and telecommunications (Yellowlees & Brooks, 1999). In Australia, the health system, like others in developed countries worldwide, is deteriorating quickly. Productivity commission reports, parliamentary inquiries, and numerous academic papers describe the current waste and lack of focus on outcomes in our health system (Weyden & Armstrong, 2004), at a time when communities and dedicated health professionals are screaming for the resources to provide acceptable care for their communities (Jackson, 2005). Portals are seen as feasible tools capable of influencing the outdated health framework to reflect the changed environment (Carbone & Burgess, 2006; Glenton, Paulsen, & Oxman, 2005; Martin & Sturmberg, 2005). In Australia, the technologies behind portals, and potential for health portals specifically, seem to be well understood and represented in the available literature (Sellitto & Burgess, 2005; Tatnall 2005; Tatnall, Burgess, & Singh 2004) as it is around the globe (Eysenbach, 2000; Kim, Thomas, Deering, & Maxfield, 1999; Milicevic & Cullen, 2005). However, less clear are the perceived needs of Australian general practitioners (GPs) and the issues that prevent or encourage the utilisation of these information system technologies. Not just the personal, but also the infrastructure and content needs of general practice and its patients. However, before portal development and design can begin, it is important to find out what the needs are of general practitioners. This article aims at evaluating the available literature on the most basic online information needs of general practitioners in Australia. In particular, three online issues that appear to be of most importance to GPs: Internet access and use, the content and perceptions of what GPs need, and their relationship with the Internet informed patient. It is not the intention of this article to provide a generic model to deals with the technical issues. bAcKground","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129770632","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}

Discussion of these advantages centers on improved information access via either customized access to selected information sources or through the improvements brought about by content management applications. A Web portal can provide functionalities that customize and personalize information flow to the Web surfers (Hoffman & Novak, 1996). In addition, it not only serves as a traditional advertising media, but also as an integrated marketing communication tool (Bush et al., 1998). Although it may be seen as an exciting tool of this kind, its effectiveness in terms of consumer engagement and persuasion has yet to be demonstrated empirically (Bezjian-Avery, Calder, & Iacobucci, 1998). To date, consumer behavior on the Web portal has been examined to assess whether Web portal marketing communication has been effective, but further empirical study is required to establish whether evaluating that effectiveness on the basis of Web portal consumer behavior is in fact a valid form of measurement (Bucklin & Sismeiro, 2003). Specifically, it is not clear whether an increase in visit duration corresponds with an increased positive attitude towards a Web portal site, that is, whether more time spent on a site, is an increasingly favorable reflection on its content (Balabanis & Reynolds, 2001). Some researchers argue that consumer browsing experience and involvement with a Web portal site affect visit duration (Bucklin & Sismeiro, 2003). In addition, the nature of Web browsing mechanism, such as a cache, proxy, and dynamic IP might give rise to the undercounting problem of visit duration (Berthon, Pitt, & Watson, 1996). Therefore, validating the effectiveness remains impossible until Web behavior measures, such as visit duration, can be empirically proven to represent consumer attitudes. Until then, relying on such measurement is only conjecture. The objective of this research is to determine whether visit duration serves a proxy of Web surfer’s preferences towards the Web portal content. An individual-based browsing behavior tracking methodology is employed and a set of experimental Web pages were designed on the theoretical basis of conjoint analysis to accurately measure visit duration by individual consumers. We will begin by examining various ways of measuring Web portal consumer behavior. Next we will consider the importance of content on the Web portal. An examination of this relationship may answer the question of whether visit duration is indicative of marketing effectiveness on the portal. The marketing effectiveness variable under consideration is portal content, with site design operating as a control variable.","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127237573","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}

According to Ronaghan (2002) and Musgrave (2004), the use of computers and ICT by government departments becomes a significant part of the service delivery mechanism, and egovernment programs remain at the top of most countries policy agendas. Enthusiasm for e-government may be justified by its widely recognized potential to improve efficiency, effectiveness, and quality of public services (Ancarani, 2005; Buckley, 2003; Ronaghan, 2002). E-government may connect dispersed and disparate systems to give access to information and work to common service level delivery through a gateway portal, which provides information to users and supports one-stop transactions through a single point of contact, avoiding the need for dealing directly with different government agencies (Kaaya, 2004, Musgrave, 2004). For example, the Tunisian national government portal (www. bawaba.gov.tn) has links to ministries having Web sites and to postal e-services. Portals allow better online service delivery by facilitating ease of access to information and services and reducing costs of services provision. Nevertheless, only a well-composed portal can add substantial value and signal important potential benefits to consumers (Van Riel & Ouwersloot, 2005), leading to better service quality. Several studies attempted to identify service quality attributes in online service environments (Cai & Jun, 2003; O’Neil, Wright, & Fitz, 2001; Tan, Xie, & Li, 2003), but they seem to focus on private organizations (Buckley, 2003). In fact, in the context of public organizations, less concern is given to service quality (Buckley, 2003), and research on eservices quality in public area is still in its infancy (Ancarani, 2005; Barnes & Vidgen, 2004; Buckley, 2003). This article proposes, at a first time, an overview of works on e-government portals and e-service quality in both private and public sector. At a second time, authors will identify, using the cited works, dimensions, and items to measure eservice quality in the case of e-government portals.","PeriodicalId":349521,"journal":{"name":"Encyclopedia of Portal Technologies and Applications","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121488576","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}

A Google search on the Web for the word revealed 25.6 million entries in December 2003. Due to a considerable degree of overuse and overlap, portals are seen everywhere and it would be difficult to make any use of the Web without encountering one (Tatnall, 2004). According to White (2000), a portal provides user-customizable access to information and applications through a Web browser. Tatnall (2004) specifies that a portal aggregates information from multiple sources and makes that information available to various users. In other words, a portal can be defined as an integrated and personalized Web-based application that provides the end user with a single point of access to a wide variety of aggregated content anytime and from anywhere using any Web-enabled client device. From a technical point of view, utilizing portals based on Internet technology is a new approach to facilitate information management including information dissemination, information access, information share, and information exchange. Due to the expansion of the Internet, portal users might spread all over the world. In a global environment, there are a number of differences from country to country. Some of those differences could tremendously influence portal design, portal implementation, as well as portal application in a global context. In this short article, the effort will be put on studying several influential factors that could affect portal design from a global point of view. The study results should benefit information technology managers, educators, and students involved in business intelligence, information systems management, information resource management, and knowledge management. Particularly, the discussions about influential factors could contribute further to portal design, portal implementation, and portal utilization for various international, transnational, and multinational businesses.
