    On Contending with Unruly Neighbors in the Global Village: Viewing Information Systems as Both Weapon and Target

    Get PDF
    While information technologies we employ in business, government, and society have dramatically enhanced our ability to conduct commerce, the vulnerabilities of these systems create potential dangers not often fully apprehended. As an example, criminal and terrorist groups have demonstrated a sophisticated understanding of how to adapt organizational forms and information technologies to advance their agendas, regardless of how contemptible these may be. In this article, we consider how these groups may view information technology and systems both as means by which they may more effectively organize themselves and as potential targets as they subvert the underlying societal assumptions regarding the technology itself. Topics such as these have implications for both IS research and practice because the changing nature of warfare means entities that may have until recently been seen as “non-combatant” are no longer viewed as such; any organization’s online resources may be regarded and serviced as legitimate targets. This fact, coupled with the interconnectedness of the global economy, makes it imperative to understand the potential threat—whether this is acted on by criminals, terrorists, or even by hostile nation states—and place greater emphasis on defending vital systems against such attacks

    The purpose of this paper is to demonstrate that it is feasible for the student health center to leverage existing clinical data in a data warehouse by using OLAP reporting in order to improve patient care and health care services decision making. Historically, University health care centers have relied mainly on operational data sources for critical health care decision making. These sources of data do not contain enough information to allow health officials to recognize trends or predict how future changes in health care services might vastly improve overall heath care. Four proof of concept artifacts are constructed through design science research methodology, and a feasibility study is presented to build the case for the adoption of OLAP reporting technology. The study concludes that it is feasible to implement an OLAP reporting infrastructure at the student health center if physicians, clinical staff, and administration clearly define the need for the new technology, develop proper data extraction, loading, and transformation strategy, and adequately provide project management and data warehouse design towards the implementation of the solution

    Prof. Dr. Jens Schröter, Christoph Borbach, Max Kanderske und Prof. Dr. Benjamin Beil sind Herausgeber der Reihe. Die Herausgeber*innen der einzelnen Hefte sind renommierte Wissenschaftler*innen aus dem In- und Ausland.Technologies and especially media technologies are pervasive in modern societies. But even more omnipresent are the imaginaries of modern technologies – what technologies are thought to be capable of or what effects they are supposed to have. These imaginations reveal a lot of the political and ideological self-descriptions of societies, hence the (techno-)imaginary also functions as a kind of epistemic tool. Concepts of the imaginary therefore have experienced an increasing attention in cultural theory and the social sciences in recent years. In particular, work from political philosophy, but also approaches from science and technology studies (STS) or communication and media studies are worth mentioning here. The term "techno-imagination", coined by Vilém Flusser in the early 1990s, refers to the close interconnection of (digital) media and imaginations, whose coupling can not only be understood as a driver of future technology via fictional discourses (e.g. science fiction), but much more fundamentally also as a constitutive element of society and sociality itself, as Castoriadis has argued. In the first part of the issue several theoretical contributions add new aspects to the discussion of socio-technical imaginaries, while in the second part a workshop held in January 2022 at the CAIS in Bochum is documented, in which the case of the imaginaries of “Future Internets” was discussed

    Am Geographischen Institut der Humboldt Universität zu Berlin wird täglich mit räumlichen Daten gearbeitet. Die erfolgreiche Arbeit von Forschungsgruppen, Lehrtätigen und Studenten basiert auf brauchbaren Datengrundlagen. Um diese Fülle von Ressourcen überschaubar zu organisieren wird seit einigen Jahren eine Geodateninfrastruktur unterhalten. Sie verfügt - neben anderen Anwendungen - über ein Geoportal, das dem Benutzer erlaubt auf die Geodatenbanken des Instituts zuzugreifen. Die Geodateninfrastruktur erlaubt dem Benutzer Ressourcen institutsweit zu suchen, anzuzeigen und (wieder) zu benutzen. Durch dieses kooperative Netzwerk sollen Synergieeffekte erzielt werden da Beschaffungskosten für Neudaten entfallen. Zusätzlich kann die Geodateninfrastruktur Lehrtätigkeit unterstützen und als praktisches Beispiel in den Lehrplan integriert werden. Kernstück dieses virtuellen Netzwerks sind Metadaten. Sie ermöglichen die umfassende Beschreibung der Ressourcen des Instituts, sowie Suche und Identifikation von Ressourcen durch das Geoportal. Der Metadaten Katalog des Instituts dient der Organisation dieser Metadaten in standardisierter Form. Das Ziel der vorliegenden Arbeit ist es, ein neues Metadaten Management Systems für die Geodateninfrastruktur des Geographischen Instituts zu implementieren. Der am Ende stehende funktionsfähige Prototyp soll vom Leitbild des „user-centric SDI“ Ansatzes geprägt sein. Dieses Konzept repräsentiert die nunmehr dritte Generation von Geodatenbanken und rückt den Benutzer in das Zentrum der Aufmerksamkeit - und dies von Beginn des Implementierungsprozesses an. Der gesamte Arbeitsfluss soll demzufolge stark vom Feedback der späteren Benutzer und deren Anforderungen geprägt sein. Mit „Joint Application Design“ und „Rapid Prototyping“ wurden Methoden gewählt, die diese Art von Software Entwicklung unter aktivem Nutzerengagement unterstützen. Als Folge nehmen Nutzerbefragungen, Präsentations- und Informationsveranstaltungen sowie Fragebogendesign und Auswertung in dieser Arbeit prominente Stellungen ein. Viele Weichen in der Softwareentwicklung wurden nach Auswertung von Nutzerbefragungen gestellt. Im Vorfeld wurde eine Unterteilung der Institutsmitglieder in „Experten“ und (potentielle zukünftige) „Nutzer“ getroffen. Wenige Experten wurden für grundlegende Entscheidungen herangezogen; die Nutzergemeinschaft wurde zu Informationsveranstaltungen eingeladen und mittels Fragebogen zum Thema Interface Design und der optimalen Bedienbarkeit des Geoportals befragt. Diese Veranstaltungen sollten über die Vorteile der Geodateninfrastruktur informieren, und durch aktive Beteiligung die Nutzergemeinschaft zu stärken und zu vergrößern. Jede GDI basiert auf Kommunikations- und Kooperationsprozessen, weshalb diese Aktivitäten Garanten für eine langfristig erfolgreiche Initiative darstellen. Eine vorangegangene Software Evaluation ließ, unter Berücksichtigung der gesammelten Nutzeranforderungen, für das Softwarepacket GeoNetwork open source entscheiden. Die Technische Entwicklung und die Gestaltung der Computer-Nutzer-Schnittstellen des GeoNetwork Prototypen wurden in sich wiederholenden Feedbackschleifen geplant. Abwechselnd soll die Generierung neuer Prototypen auf erneute Präsentationen inklusive Nutzerbefragungen folgen. Die Ergebnisse dieser Befragungen geben die Richtung für weitere Arbeit am Prototyp vor. Als methodischer Rahmen diente der „Rapid Prototyping“ Ansatz. Diskussionen in der Runde der Experten sowie die ständige Einbindung dieser in wichtige Entscheidungen rund um die GDI soll Teambildung fördern und die Mitglieder der Expertenrunde an das Projekt binden. Sie sind es, die später Verantwortlichkeiten für Metadaten übernehmen und delegieren können und damit einen wichtigen Beitrag zur Wartung und Instanthaltung der Infrastruktur leisten. Vorliegende Arbeit beschreibt Planung, Umsetzung und Ergebnis des Implementierungsprozesses dieses Prototyps unter Anwendung spezieller, auf Benutzer Partizipation und Feedback aufbauender Methoden. Es wird am Beispiel der speziellen Fallstudie diskutiert wie weit die gewählten Methoden im Sinne des Konzept des „unser-centric SDI“ eingesetzt werden und wie diese Praxis nachhaltig die Benutzerzufriedenheit steigert und zum Erfolg einer GDI langfristig beiträgt. Die Arbeit schließt mit einem Ausblick in die nahe und ferne Zukunft der möglichen Weiterentwicklung der GDI des Geographischen Instituts.Working with spatial data is “daily bread” at the Department of Geography at Humboldt Universität zu Berlin. The success of research projects, staff members’ work and students’ university routines depends on high quality data and resources. A couple of years ago the department’s own Spatial Data Infrastructure was founded to organize and publish these resources and corresponding metadata. This virtual infrastructure offers a geoportal that allows the user to discover, visualize and (re-)use the department’s spatial and aspatial resources. Maintaining this cooperative network aims at synergy effects like reduction of costs for the acquirement of new resources. Moreover, SDI can be used to support teaching activities and serve as a practical example in the curriculum. Central for SDI are metadata; they represent a comprehensive structured description of the department’s resources and are a core piece of the geoportal’s functionalities to discover and identify data. The department’s Metadata Catalogue serves as a container for structured organization of metadata. This project goal is the implementation of a new metadata management system for the department’s Spatial Data Infrastructure. The resulting prototype should be developed following the user-centric SDI (third generation SDI) paradigm. This approach considers the (possible future) user community’s requirements and feedback as highly important and suggests an implementation process with continuous user participation. Both methods, “Joint Application Design” and “Rapid Prototyping”, rely on active user participation and were chosen and applied to support this concept. As a consequence, user assessments, information and dissemination activities and design and analysis of questionnaires occupied a prominent part of this study; the most important decisions during the implementation process were based on user feedback. In the forefront, users were distinguished between (possible future) “users” and “experts”. A small group of experts was asked to discuss and make fundamental decisions about the department’s SDI development, and the community of users was invited to informative events and to participate by filling out a questionnaire about the geoportal’s usability and interface design. These events were expected to raise user interest, foster a user community and user participation and to provide information about usage and benefits of the department’s SDI. SDI, as a communication and cooperation network, benefits from these activities in the long run. A preliminary software evaluation and the assessment of user requirements led to the decision that GeoNetwork open source was the most promising software to replace the department’s current metadata management system. Technical development and implementation of GeoNetwork prototype and its interfaces was accompanied by continuous feedback loops in accordance with the concept of “Rapid Prototyping”. The development of each new version of the prototype is followed by the presentation to users and collection of feedback. This feedback sets the agenda for further developments. Members of the expert group were constantly invited to participate in the SDI implementation process. Discussions regarding elemental SDI issues should foster team building and should bind experts to the project. They are the ones who are needed to take over custodianship for resources and metadata and to therefore play central roles in maintaining the department’s SDI. The thesis at hand describes the planning, design, realization and results of the implementation of a metadata management system prototype, by facilitating special, user participation methods. Using the example of this special case it discusses the combination of these methods with a user-centric SDI approach and implications in terms of user satisfaction and long-term SDI success. The final chapter offers a discussion about the implementation process and closes with an outlook on the possible short and long term development of the department of Geography’s SDI node

    Advertising in Audio Podcasts has gained huge popularity in the last years. However, education on how to advertise effectively on Podcasts is still at an early stage. A high effectiveness of advertising is only achieved when an advertisement is placed and consumed in the appropriate media context. The placement and its effectiveness are a topic that still needs to be researched intensively in this regard. The ad-context congruence, the correspondence of theme and image between a brand being advertised and a podcast episode are explored more intensively in this work. These are common criteria used for the selection of advertising contexts. For the purpose of a deeper investigation of this topic, two experimental online surveys were realised. Here, either the thematic congruence or the image congruence and their advertising effectiveness were examined. Audio sequences of German podcast episodes were played to the panel participants. Fictitious podcast advertisements were inserted into these. These advertisements contextually fitted the episode either very well or not at all. After participants have been exposed to one audio sequence, advertising effectiveness was measured by the variables brand recall, brand recognition and attitudes towards the brand. Brand recall and brand recognition were higher in percentage terms for the thematic and image congruent condition. However, the study did not yield statistically significant results for these variables. Nevertheless, experiments demonstrate that thematic but also image congruence had a strong and statistically significant impact on attitudes towards the brand. In both experiments, the congruent condition was able to trigger a much more positive evaluation of the brand than the non-congruent one.Nos últimos anos, a publicidade em Podcasts áudio ganhou uma enorme popularidade. Noentanto, a formação para anunciar eficazmente em Podcasts está ainda na sua fase inicial. Só é possível alcançar um alto nível de eficácia publicitária se uma publicidade for colocada e consumida no contexto de media adequado. A colocação e eficácia é um tópico que ainda precisa de ser intensamente pesquisado neste âmbito. A congruência do contexto publicitário, assim como a correspondência entre o tema e a imagem da marca que está a ser publicitada e o episódio do Podcast em causa, são explorados de forma mais aprofundada neste trabalho. Estes são os critérios mais comuns usados para selecionar os contextos publicitários. Foram conduzidas duas sondagens experimentais online, com o intuito de aprofundar a investigação neste tópico. Através delas, foram examinadas a congruência temática ou a congruência de imagem, assim como a eficácia publicitária. Foram reproduzidas sequências de áudio de Podcasts alemães para que os participantes dos painéis as escutassem. Durante a reprodução, foram inseridos anúncios de Podcast fictícios. O nível de adequação destes anúncios ao episódio variava entre “muito adequados” e “nada adequados”. Depois de os participantes terem sido expostos a uma sequência de áudio, foi medida a eficácia publicitária do anúncio através das variáveis respeitantes à memória de marca, reconhecimento de marca e atitude perante a marca. A memória de marca e o reconhecimento de marca obtiveram mais pontos em termos percentuais quando se verificavam condições de congruência temática e de imagem. No entanto, o estudo não providenciou resultados estatisticamente significantes para estas variáveis. Não obstante, as experiências demonstras que a congruência temática – e também a de imagem – tem um impacto estatístico significativo nas atitudes perante a marca. Em ambas as experiências, a condição de congruência conseguiu desencadear uma avaliação muito mais positiva da marca quando comparada com uma condição de incongruência

    “The swift emergence of a global “information society” is changing the way people live, learn, work and relate. An explosion in the free flow of information and ideas has brought knowledge and its myriad applications to many millions of people, creating new choices and opportunities in some of the most vital realms of human endeavour. Yet too many of the world's people remain untouched by this revolution. A “digital divide” threatens to exacerbate already-wide gaps between rich and poor, within and among countries. The stakes are high indeed. Timely access to news and information can promote trade, education, employment, health and wealth. One of the hallmarks of the information society – openness -- is a crucial ingredient of democracy and good governance. Information and knowledge are also at the heart of efforts to strengthen tolerance, mutual understanding and respect for diversity……….. …The new information and communications technologies are among the driving forces of globalization. They are bringing people together, and bringing decision makers unprecedented new tools for development. At the same time, however, the gap between information 'haves' and 'have-nots' is widening, and there is a real danger that the world's poor will be excluded from the emerging knowledge-based global economy.”Information Society, Jamaica Information society,Jamaica,Government, e-government
