    Unified Messaging Systems: an Evolutionary Overview

    Get PDF
    Over the last decade, the widespread demand and use of the internet has changed the direction of the telecommunications industry as it was recognised that the internet could be used as an inexpensive way to handle not only data but also voice communications. This convergence of traditional voice and data technologies towards an IP-based open architecture has been paralleled by a convergence of the internet and mobile communications. As a result of these convergences, unified messaging has emerged as a technically viable service. Integrated messaging services that offer partial unification of different message types are already in the marketplace. This paper asks what unified messaging means and examines underlying architectural developments that are likely to shape the unified messaging applications of the future

    Residence hall sense of community in physical and technology-based spaces: Implications for alcohol-related attitudes and behaviors

    Get PDF
    Social experiences such as sense of community (SOC) and peer norms have the potential to influence attitudes and behaviors around a host of wellness-related issues. Social interaction, facilitated by the rapid growth of communication technology, in addition to the enduring need to interact in physical space, represent important community features. College residence halls are of interest to community psychology and other fields, as they are highly interactive, technologically-rich contexts where communities occur. Peer norms having a strong relationship to students’ perspectives and choices around alcohol. Less understood is the role that SOC plays, and the forms of social interaction that generate a SOC. The current study examined social interaction and SOC, including the role of SOC and peer norms in impacting alcohol-related attitudes and behaviors. Online survey data for 1003 undergraduate students residing in residence halls at a large, private, Midwestern university were analyzed. Physical and communication technology-based interaction was measured. SOC and both injunctive and descriptive peer norms were measured, along with frequency of alcohol use, interest in alcohol-free social programming, support for alcohol-related hall policies, and alcohol use in one’s own hall. Findings suggested that both physical and communication-technology-based social interaction related to a students’ SOC, with face-to-face interaction having a substantially greater impact. Peer norms for alcohol use, but not SOC, were related to frequency of use and rates of binge drinking. SOC in residence halls and peer norms were related to alcohol-free programming in residence halls, with SOC being more strongly related. SOC and peer norms for alcohol use were related to support for policies concerning alcohol use and use of alcohol in one’s hall, with peer norms being stronger predictors than SOC. Findings are relevant to theory as it relates to SOC, as they examine overlapping physical and technology-based social spaces experienced within the same community. Findings can benefit student affairs and others concerned with promoting campus wellness, and can direct future research on substance use. The project underscores the important role that collaborative relationships between community researchers and residential education departments can have in promoting student wellness and expanding knowledge of community experience

    Strategic Positioning in Converging Technology Markets—The Clyp Case

    Get PDF
    This case is set in the market for Internet telephony software, which emerged as the result of the convergence of traditional telecommunications technology with new Internet-based speech technology. Clyp is the provider of a software-based IP-PBX, a public branch exchange, which allows companies to set up and self-manage an internal IP-based telephony network, whereby telephony and data share the same computer network infrastructure. Clyp finds itself confronted with an increasingly competitive and converging market. Its growth rates have fallen behind market average, and its product hasn’t seen innovative changes for some time. The case is targeted at Postgraduate (master’s-level) students in (business) information systems and strategic (technology) management. Its main aim is to facilitate learning on strategic positioning and business model analysis in the faces of converging technology markets and the unique characteristics of a software company. The case lends itself to a three-step analysis: (1) business model analysis, (2) market analysis and strategic positioning, (3) identification of strategic options

    Network Convergence: Where is the Value?

    Get PDF
    The entire telecommunications industry is going through very difficult times. Rapidly changing technology, lack of good business models, and lack of visibility in the near-term for renewed growth all create an uncertain environment. Yet, the global Internet is becoming a multi-service network infrastructure that can potentially replace existing disparate voice and data networks. Although it is widely believed in the telecommunications industry that network convergence of voice, data, video, and images is an industry driver, not much attention has yet been paid to a key proposition: what value does network convergence bring to business and residential customers? This paper explains how different industries are converging; the technological, economic and regulatory forces that are at play and how the various customer segments can benefit from network convergence. While technological advancement is transforming industry and business models rapidly, one question keeps coming back to haunt managers: Where is the business value? We illustrate the value proposition of convergence (for various players) by first explaining the paradigm shifts happening across industries and then highlighting the high velocity spiral of knowledge dissemination theory that is fueled by convergence

    Promoting Health for Chronic Conditions: a Novel Approach that integrates Clinical and Personal Decision Support

    Get PDF
    Direct and indirect economic costs related to chronic diseases are increasing in Europe due to the aging of population. One of the most challenging goals is to improve the quality of life of patients affected by chronic conditions, and enhance their self-management. In this paper, we propose a novel architecture of a scalable solution, based on mobile tools, aimed to keep patients with chronic diseases away from acute episodes, to improve their quality of life and, consequently, to reduce their economic impact. Our solution aims to provide patients with a personalized tool for improving self-management, and it supports both patients and clinicians in decision-making through the implementation of two different Decision Support Systems. Moreover, the proposed architecture takes into account the interoperability and, particularly, the compliance with data transfer protocols (e.g., BT4/LE, ANT+, ISO/IEEE 11073) to ensure integration with existing devices, and with the semantic web approaches and standards related to the content and structure of the information (e.g., HL7, ICD-10 and openEHR) to ensure correct sharing of information with hospital information systems, and classification of patient behaviors (Coelition). The solution will be implemented and validated in future study

    SOAR4IoT: Securing IoT Assets with Digital Twins

    Get PDF
    As more and more security tools provide organizations with cybersecurity capabilities, security analysts are overwhelmed by security events. Resolving these events is challenging due to extensive manual processes, limited financial resources, and human errors. Security Orchestration, Automation, and Response (SOAR) is an established approach to manage security tools and assets. However, SOAR platforms typically integrate traditional IT systems only. Additional considerations are required to deal with the Internet of Things (IoT), its multiple devices and complex networks. Therefore, we adapt SOAR to IoT. We first aggregate existing research and information on SOAR and SOAR platforms. We envision the SOAR4IoT framework, making IoT assets manageable for SOAR via middleware. We implement a prototypical digital twin-based SOAR application integrating IoT assets and security tools to validate our framework. The experimental setup includes two playbooks coping with Mirai and Sybil attacks. Results show feasibility as our SOAR application enables securing IoT assets with digital twins
