    Get PDF
    In the new age of information technology, big data has grown to be the prominent phenomena. As information technology evolves, organizations have begun to adopt big data and apply it as a tool throughout their decision-making processes. Research on big data has grown in the past years however mainly from a technical stance and there is a void in business related cases. This thesis fills the gap in the research by addressing big data challenges and failure cases. The Technology-Organization-Environment framework was applied to carry out a literature review on trends in Business Intelligence and Knowledge management information system failures. A review of extant literature was carried out using a collection of leading information system journals. Academic papers and articles on big data, Business Intelligence, Decision Support Systems, and Knowledge Management systems were studied from both failure and success aspects in order to build a model for big data failure. I continue and delineate the contribution of the Information System failure literature as it is the principal dynamics behind technology-organization-environment framework. The gathered literature was then categorised and a failure model was developed from the identified critical failure points. The failure constructs were further categorized, defined, and tabulated into a contextual diagram. The developed model and table were designed to act as comprehensive starting point and as general guidance for academics, CIOs or other system stakeholders to facilitate decision-making in big data adoption process by measuring the effect of technological, organizational, and environmental variables with perceived benefits, dissatisfaction and discontinued use.siirretty Doriast

    The First 25 Years of the Bled eConference: Themes and Impacts

    Get PDF
    The Bled eConference is the longest-running themed conference associated with the Information Systems discipline. The focus throughout its first quarter-century has been the application of electronic tools, migrating progressively from Electronic Data Interchange (EDI) via Inter-Organisational Systems (IOS) and eCommerce to encompass all aspects of the use of networking facilities in industry and government, and more recently by individuals, groups and society as a whole. This paper reports on an examination of the conference titles and of the titles and abstracts of the 773 refereed papers published in the Proceedings since 1995. This identified a long and strong focus on categories of electronic business and corporate perspectives, which has broadened in recent years to encompass the democratic, the social and the personal. The conference\u27s extend well beyond the papers and their thousands of citations and tens of thousands of downloads. Other impacts have included innovative forms of support for the development of large numbers of graduate students, and the many international research collaborations that have been conceived and developed in a beautiful lake-side setting in Slovenia

    Semantic discovery and reuse of business process patterns

    Get PDF
    Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

    Patient cost sharing - reforms without evidence: theoretical considerations and empirical findings from industrialized countries

    Full text link
    "International health service research reveals a uniform tendency in practically all industrialised countries: an increasing shift of costs from solidarity-based financing to private households. Legislators and advisors usually justify this policy through the need to encourage cost-consciousness and especially 'individual responsibility'. Economists consider cost-sharing in health care to be necessary to prevent abuse of the welfare state. They expect user charges and co-payments to motivate a more 'rational' utilisation of health care and, thus, the financial stabilisation of health systems. Many politicians and economists base their assumptions about the 'health market' on the theorem of demand-side moral hazard. This model transforms patients into rational 'utility maximisers' consuming services beyond their needs thereby causing welfare losses to society as a whole. Moral hazard in health insurance belongs to the standard repertoires of economic textbooks. The present study analyses the extensive theoretical and empirical literature on patient cost-sharing published during the last forty years. The results show that persuasive evidence for demand-side moral hazard is still lacking. Furthermore, the claimed empiricism turns out to be inappropriate for providing evidence. Science health service research and clinical studies instead suggest that health insurance beneficiaries are not aiming to abuse the health system. In fact, introducing patient cost-sharing seems to endanger proper health care since it deters the sick from claiming benefits. The idea of 'rational' use transpires to be out of touch with reality. After a systematic in-depth review of current research on the topic, the author concludes that moral hazard in health insurance is a bogey of academic economic theory. Adequate reality-based evidence for implementing patient user fees and co-payments is lacking. In view of the detrimental effects on health service utilisation, he advises cancelling existing co-payment arrangements and abandoning cost-sharing policies." (author's abstract)"Die internationale Gesundheitssystemforschung zeigt in praktisch allen IndustrielĂ€ndern einen einheitlichen Trend auf: die zunehmende Verlagerung der Kosten von der solidarischen Finanzierung auf die privaten Haushalte. Gesetzgeber wie Berater begrĂŒnden dies ĂŒblicherweise mit der StĂ€rkung von Kostenbewusstsein und vor allem der 'Eigenverantwortung'. Wirtschaftswissenschaftler betrachten Selbstbeteiligungen in der Gesundheitsversorgung als notwendig, um dem Missbrauch der Solidargemeinschaft entgegenzuwirken. Von GebĂŒhren und Zuzahlungen erwarten sie eine 'vernĂŒnftigere' Inanspruchnahme der Gesundheitsleistungen und eine finanzielle Stabilisierung der Systeme. Die Sicht vieler Politiker und Wirtschaftsexperten auf den 'Gesundheitsmarkt' ist durch das Theorem des versichertenseitigen Moral Hazard geprĂ€gt. Dieses Modell macht Krankenversicherte zu rationalen 'Nutzenmaximierern', die zum eigenen Vorteil ĂŒber den Bedarf hinaus Leistungen in Anspruch nĂ€hmen und dadurch gesamtgesellschaftliche Wohlfahrtsverluste verursachten. Moral Hazard in der Krankenversicherung gehört zum Standard-Repertoire ökonomischer LehrbĂŒcher. Die vorliegende Arbeit wertet die umfangreiche Literatur ĂŒber AnsĂ€tze und Versuche der Kostenbeteiligung von Patienten aus, die in den letzten vier Jahrzehnten erschienen ist. Dabei stellt sich heraus, dass belastbare Belege fĂŒr das Moral-Hazard-Verhalten von Versicherten bzw. Patienten bisher fehlen und die ĂŒblicherweise angefĂŒhrte Empirie fĂŒr den Nachweis ungeeignet ist. Gesundheitswissenschaftliche, versorgungsbezogene und klinische Studien legen vielmehr nahe, dass die Versicherten das System nicht ausnutzen wollen oder können. Die EinfĂŒhrung von Kostenbeteiligungen fĂŒr Patienten scheint eher die bedarfsgerechte Versorgung zu gefĂ€hrden, weil sie Kranke von der Inanspruchnahme abhalten. Die Vorstellung von der 'rationalen' Nutzung des Gesundheitswesens entpuppt sich als realitĂ€tsfremd. Nach grĂŒndlicher Auswertung des Forschungsstandes kommt der Autor zum Schluss, dass Moral Hazard in der Krankenversicherung ein Popanz der akademischen Wirtschaftstheorie geblieben ist. FĂŒr die EinfĂŒhrung von Kostenbeteiligungen fĂŒr Patienten fehlt es an hinreichender realitĂ€tsbasierter Evidenz. In Anbetracht der schĂ€dlichen versorgungspolitischen Effekte erscheinen die RĂŒcknahme aller Patientenzuzahlungen und der Verzicht auf Selbstbeteiligungen geboten." (Autorenreferat

    It came from outer space: the virus, cultural anxiety, and speculative fiction

    ï»żThis study seeks to explore and interrogate the “viral reality” of the 1990s, in which the virus, heavily indebted to representations of AIDS for its metaphorical power, emerged as a prominent agent in science and popular culture. What becomes apparent in both fictional and non-fictional texts of this era, however, is that the designation of “virus” transcends specific and material viral phenomena, making the virus itself a touchstone for modern preoccupations with self and other. As constituted by the human body’s interaction with pathogenic agents, the binary of self and other may be deconstructed by an interrogation of the virus itself, a permeable and mutable body that lends itself to any number of interpretive possibilities. A uniquely liminal agent, the virus refuses categorization as either life or non-life. However, it is not the liminality of the pathogen that allows for this deconstruction, which serves to frustrate such boundaries in the first place. Rather, the notion that viruses are (always) already a part of who we are as human beings, and that “self” is not necessarily a self-enclosed autonomous entity, suggests that the binary cannot hold. A virus is unique; an insider/outsider that crosses artificial boundaries, it destabilizes the boundaries themselves, and thus the traditional framework of self and other. Examining viral accounts in popular science writings, film, television, advertisements, philosophy, science fiction, and naturalistic fiction, this study examines the ways in which science and popular culture have characterized both the virus and its psychological and material effects, and suggests that the pathogen-as-signifier may be read in ways that point to the virus’s utopian potential as a theoretical category

    Accessing different physical objects at any time from anywhere through wireless network heavily impacts the living style of societies worldwide nowadays. Thus, the Internet of Things has now become a hot emerging paradigm in computing environments. Issues like interoperability, software reusability, and platform independence of those physical objects are considered the main current challenges. This raises the need for appropriate software engineering approaches to develop effective and efficient IoT applications software. This paper studies the state of the art of design and development methodologies for IoT software. The aim is to study how proposed approaches have been solved issues of interoperability, reusability, and independence of the platform. A comparative study is presented for the different software engineering methods used for the Internet of Things. Finally, the key research gaps and open issues are highlighted as future directions

    Augmentation of Brain Function: Facts, Fiction and Controversy. Volume III: From Clinical Applications to Ethical Issues and Futuristic Ideas

    Get PDF
    The final volume in this tripartite series on Brain Augmentation is entitled “From Clinical Applications to Ethical Issues and Futuristic Ideas”. Many of the articles within this volume deal with translational efforts taking the results of experiments on laboratory animals and applying them to humans. In many cases, these interventions are intended to help people with disabilities in such a way so as to either restore or extend brain function. Traditionally, therapies in brain augmentation have included electrical and pharmacological techniques. In contrast, some of the techniques discussed in this volume add specificity by targeting select neural populations. This approach opens the door to where and how to promote the best interventions. Along the way, results have empowered the medical profession by expanding their understanding of brain function. Articles in this volume relate novel clinical solutions for a host of neurological and psychiatric conditions such as stroke, Parkinson’s disease, Huntington’s disease, epilepsy, dementia, Alzheimer’s disease, autism spectrum disorders (ASD), traumatic brain injury, and disorders of consciousness. In disease, symptoms and signs denote a departure from normal function. Brain augmentation has now been used to target both the core symptoms that provide specificity in the diagnosis of a disease, as well as other constitutional symptoms that may greatly handicap the individual. The volume provides a report on the use of repetitive transcranial magnetic stimulation (rTMS) in ASD with reported improvements of core deficits (i.e., executive functions). TMS in this regard departs from the present-day trend towards symptomatic treatment that leaves unaltered the root cause of the condition. In diseases, such as schizophrenia, brain augmentation approaches hold promise to avoid lengthy pharmacological interventions that are usually riddled with side effects or those with limiting returns as in the case of Parkinson’s disease. Brain stimulation can also be used to treat auditory verbal hallucination, visuospatial (hemispatial) neglect, and pain in patients suffering from multiple sclerosis. The brain acts as a telecommunication transceiver wherein different bandwidth of frequencies (brainwave oscillations) transmit information. Their baseline levels correlate with certain behavioral states. The proper integration of brain oscillations provides for the phenomenon of binding and central coherence. Brain augmentation may foster the normalization of brain oscillations in nervous system disorders. These techniques hold the promise of being applied remotely (under the supervision of medical personnel), thus overcoming the obstacle of travel in order to obtain healthcare. At present, traditional thinking would argue the possibility of synergism among different modalities of brain augmentation as a way of increasing their overall effectiveness and improving therapeutic selectivity. Thinking outside of the box would also provide for the implementation of brain-to-brain interfaces where techniques, proper to artificial intelligence, could allow us to surpass the limits of natural selection or enable communications between several individual brains sharing memories, or even a global brain capable of self-organization. Not all brains are created equal. Brain stimulation studies suggest large individual variability in response that may affect overall recovery/treatment, or modify desired effects of a given intervention. The subject’s age, gender, hormonal levels may affect an individual’s cortical excitability. In addition, this volume discusses the role of social interactions in the operations of augmenting technologies. Finally, augmenting methods could be applied to modulate consciousness, even though its neural mechanisms are poorly understood. Finally, this volume should be taken as a debate on social, moral and ethical issues on neurotechnologies. Brain enhancement may transform the individual into someone or something else. These techniques bypass the usual routes of accommodation to environmental exigencies that exalted our personal fortitude: learning, exercising, and diet. This will allow humans to preselect desired characteristics and realize consequent rewards without having to overcome adversity through more laborious means. The concern is that humans may be playing God, and the possibility of an expanding gap in social equity where brain enhancements may be selectively available to the wealthier individuals. These issues are discussed by a number of articles in this volume. Also discussed are the relationship between the diminishment and enhancement following the application of brain-augmenting technologies, the problem of “mind control” with BMI technologies, free will the duty to use cognitive enhancers in high-responsibility professions, determining the population of people in need of brain enhancement, informed public policy, cognitive biases, and the hype caused by the development of brain- augmenting approaches

    L’émergence de l’utilisation du mĂ©thylphĂ©nidate (MPH; Ritalin) par des Ă©tudiants universitaires afin d’amĂ©liorer leur concentration et leurs performances universitaires suscite l’intĂ©rĂȘt du public et soulĂšve d’importants dĂ©bats Ă©thiques auprĂšs des spĂ©cialistes. Les diffĂ©rentes perspectives sur l’amĂ©lioration des performances cognitives reprĂ©sentent une dimension importante des dĂ©fis sociaux et Ă©thiques autour d’un tel phĂ©nomĂšne et mĂ©ritent d’ĂȘtre Ă©lucidĂ©es. Ce mĂ©moire vise Ă  examiner les discours prĂ©sents dans les reportages internationaux de presse populaire, les discours en bioĂ©thique et en en santĂ© publique sur le thĂšme de l’utilisation non mĂ©dicale du mĂ©thylphĂ©nidate. Cette recherche a permis d’identifier et d’analyser des « lacunes » dans les perspectives Ă©thiques, sociales et scientifiques de l’utilisation non mĂ©dicale du mĂ©thylphĂ©nidate pour accroĂźtre la performance cognitive d’individus en santĂ©. Une analyse systĂ©matique du contenu des discours sur l’utilisation non mĂ©dicale du mĂ©thylphĂ©nidate pour accroĂźtre la performance cognitive a identifiĂ© des paradigmes divergents employĂ©s pour dĂ©crire l’utilisation non mĂ©dicale du mĂ©thylphĂ©nidate et discuter ses consĂ©quences Ă©thiques. Les paradigmes « choix de mode de vie », « abus de mĂ©dicament » et « amĂ©lioration de la cognition » sont prĂ©sents dans les discours de la presse populaire, de la bioĂ©thique et de la santĂ© publique respectivement. Parmi les principales diffĂ©rences entre ces paradigmes, on retrouve : la description de l’utilisation non mĂ©dicale d’agents neuropharmacologiques pour l’amĂ©lioration des performances, les risques et bĂ©nĂ©fices qui y sont associĂ©s, la discussion d’enjeux Ă©thiques et sociaux et des stratĂ©gies de prĂ©vention et les dĂ©fis associĂ©s Ă  l’augmentation de la prĂ©valence de ce phĂ©nomĂšne. La divergence de ces paradigmes reflĂšte le pluralisme des perceptions de l’utilisation non mĂ©dicale d’agents neuropharmacologiques Nos rĂ©sultats suggĂšrent la nĂ©cessitĂ© de dĂ©bats autour de l’amĂ©lioration neuropharmacologique afin de poursuivre l’identification des enjeux et de dĂ©velopper des approches de santĂ© publique cohĂ©rentes.The non-medical use of neuropharmaceuticals has sparked ethical debates. For example, there is mounting evidence that methylphenidate (MPH; Ritalin) is being used by healthy university students to improve concentration, alertness, and academic performance, a phenomenon known as cognitive enhancement. The different perspectives on the ethics of cognitive enhancement represent an important dimension of the social and ethical challenges related to such practices but have yet to be examined thoroughly. This thesis aimed to assess existing positive and negative reports in international print media, bioethics literature, and public health literature on the use of MPH to identify and analyze gaps in the ethical, social, and scientific perspectives about the non-medical use of MPH for cognitive enhancement in healthy individuals. A systematic content analysis of discourses on the non-medical use of methylphenidate for cognitive enhancement identified divergent frameworks employed to describe the non-medical use of methylphenidate and discuss its ethical implications: The frameworks of “lifestyle choice”, “prescription drug abuse” and “cognitive enhancement” are present in print media, bioethics, and public health discourses respectively. Important differences between frameworks include the description of the non-medical use of neuropharmaceuticals for cognitive enhancement, associated risks and benefits, discussion of ethical and social issues surrounding the phenomenon and the prevention strategies and challenges to the widespread use of neuropharmaceuticals for cognitive enhancement. Diverging frameworks reflect pluralism in perceptions if the non-medical use of neuropharmaceuticals for cognitive enhancement. At this time, unacknowledged pluralism and implicit assumptions about cognitive enhancement may impede public health interventions and ethics discussions
