    Augmented Sustainability Reports: A Design Science Approach

    Sustainability reports provide stakeholders with information about a company’s efforts to balance its economic, ecological and social goals. Because of their influence on a company’s image as well as on the customers’ buying and shareholders’ investment decisions, sustainability reports are an integral part of today’s corporate online communication. Following a design science research approach, this paper describes the design, prototypical implementation and evaluation of augmented sustainability reports. In contrast to traditional PDF- or print media-based sustainability reports, augmented sustainability reports contain multimedia contextual information that is displayed depending on the user’s gaze position. In our prototype the gaze position is simulated using mouse tracking. The comparative evaluation of the prototype was conducted via a quantitative questionnaire based on the technology acceptance model (TAM). Additionally, qualitative feedback was gathered during the course of the evaluation. Traditional and augmented sustainability reports were compared on the basis of the questionnaire results which reveal room for improvement of the prototype as well as possible starting points for future research. Overall, the evaluation results indicate that our test users had a strong preference for the augmented sustainability report compared to the PDF-based report even though both alternatives had identical content

    This paper conceptualizes a hybrid package of products and services which ensures the energy efficient planning, realization and operation of IT infrastructure. It follows the well-established procedure model of product-service systems engineering and pursues a qualitative research approach that is based on two industry workshops with more than 60 participants from science and practice and on semi-structured interviews with 8 experts. Based on the findings from the interviews and the workshops, customer requirements to the hybrid package are described, a product model is developed and evaluated. Finally, an application scenario is derived

    Madness and the law: The Derrida/Foucault debate revisited

    Get PDF
    In this article the Derrida/Foucault debate is scrutinised with two closely related aims in mind: (1) reconsidering the way in which Foucault’s texts, and especially the more recently published lectures, should be read; and (2) establishing the relation between law and madness. The article firstly calls for a reading of Foucault which exceeds metaphysics with the security it offers, by taking account of Derrida’s reading of Foucault as well as of the heterogeneity of Foucault’s texts. The article reflects in detail on a text of Derrida on Foucault (‘Cogito and the History of Madness’) as well as a text of Foucault on Blanchot (‘Maurice Blanchot: The Thought from Outside’). The latter text shows that Foucault was at times acutely aware of the difficulty involved in exceeding metaphysics and that he realised the importance in this regard of a reflection on literature. These reflections tie in closely with Foucault’s History of Madness as well as with Derrida’s reflections on literature and on madness. Both Derrida and Foucault contend that law has much to learn from literature in understanding the relation between itself and madness. Literature more specifically points to law’s ‘origin’ in madness. The article contends that a failure to take seriously this origin, also in the reading of Foucault’s lectures, would amount to a denial by law of itself

    Switching on the Lights for Gene Therapy

    Strategies for non-invasive and quantitative imaging of gene expression in vivo have been developed over the past decade. Non-invasive assessment of the dynamics of gene regulation is of interest for the detection of endogenous disease-specific biological alterations (e.g., signal transduction) and for monitoring the induction and regulation of therapeutic genes (e.g., gene therapy). To demonstrate that non-invasive imaging of regulated expression of any type of gene after in vivo transduction by versatile vectors is feasible, we generated regulatable herpes simplex virus type 1 (HSV-1) amplicon vectors carrying hormone (mifepristone) or antibiotic (tetracycline) regulated promoters driving the proportional co-expression of two marker genes. Regulated gene expression was monitored by fluorescence microscopy in culture and by positron emission tomography (PET) or bioluminescence (BLI) in vivo. The induction levels evaluated in glioma models varied depending on the dose of inductor. With fluorescence microscopy and BLI being the tools for assessing gene expression in culture and animal models, and with PET being the technology for possible application in humans, the generated vectors may serve to non-invasively monitor the dynamics of any gene of interest which is proportionally co-expressed with the respective imaging marker gene in research applications aiming towards translation into clinical application

    No full text
    In diesem Beitrag wird ein hybrides Leistungsbündel konzipiert,mit dessen Hilfe die energieeffiziente Planung und Steuerungsowie der Betrieb und die Nutzung von IT-Infrastruktur sichergestelltwerden. Das Vorgehen zur Entwicklung orientiert sich aneinem etablierten Vorgehensmodell des Product-Service-Systems-Engineering und basiert auf zwei Industrieworkshops mit über 60Teilnehmern aus Wissenschaft und Praxis sowie leitfadengestützteExperteninterviews mit 8 Unternehmensvertretern. Anhand derempirischen Ergebnisse werden die aus Kundensicht bestehendenAnforderungen an das hybride Leistungsbündel erhoben, ein Produktmodellentwickelt und evaluiert sowie ein Anwendungsszenarioabgeleitet und beschrieben. Die prototypische Implementierungder Softwarekomponente des Leistungsbündels wird anhanddes Management- und Beratungscockpits sowie der zugrundeliegendenIT-Architektur erläutert
