    Syftet med den hÀr studien var att undersöka hur pedagoger tÀnker kring sitt förhÄllningssÀtt i konflikter och vilka effekter de tror att förhÄllningssÀttet kan fÄ i barngruppen. Studiens metod har varit kvalitativa intervjuer dÀr sex pedagoger frÄn olika förskolor har deltagit. Resultatet visade att deltagarna hela tiden reflekterar över sitt förhÄllningssÀtt till konflikter och varför konflikter uppstÄr. NÄgot som alla deltagare belyste var att det Àr viktigt att barnen ges verktyg för att klara konflikter sjÀlva. Flera olika strategier kunde ses pÄ hur konflikthantering gÄr till men mycket handlar om bemötande, förklaringar och att alla i slutÀndan ska kÀnna sig nöjda. Alla deltagande ansÄg att konflikter Àr lÀrande men pÄ olika plan. Bland annat handlar det om ett lÀrande utifrÄn den gemensamma respekt man bör ha mot varandra men Àven det sociala samspelet nÀmns. De slutsatser som kan dras Àr att konflikthantering i förskolan Àr en viktig del dÀr pedagogens förhÄllningssÀtt pÄverkar konfliktens utgÄng. Att ge barnen verktyg för att klara konflikter sjÀlva ses som en bra start och en central del i konflikthantering hos deltagarna

    Redescribing Health Privacy: The Importance of Health Policy

    Get PDF
    Current conversations about health information policy often tend to be based on three broad assumptions. First, many perceive a tension between regulation and innovation. We often hear that privacy regulations are keeping researchers, companies, and providers from aggregating the data they need to promote innovation. Second, aggregation of fragmented data is seen as a threat to its proper regulation, creating the risk of breaches and other misuse. Third, a prime directive for technicians and policymakers is to give patients ever more granular methods of control over data. This article questions and complicates those assumptions, which I deem (respectively) the Privacy Threat to Research, the Aggregation Threat to Privacy, and the Control Solution. This article is also intended to enrich our concepts of “fragmentation” and “integration” in health care. There is a good deal of sloganeering around “firewalls” and “vertical integration” as idealized implementations of “fragmentation” and “integration” (respective). The problem, though, is that terms like these (as well as “disruption”) are insufficiently normative to guide large-scale health system change. They describe, but they do not adequately prescribe. By examining those instances where: a) regulation promotes innovation, and b) increasing (some kinds of) availability of data actually enhances security, confidentiality, and privacy protections, this article attempts to give a richer account of the ethics of fragmentation and integration in the U.S. health care system. But, it also has a darker side, highlighting the inevitable conflicts of values created in a “reputation society” driven by stigmatizing social sorting systems. Personal data control may exacerbate social inequalities. Data aggregation may increase both our powers of research and our vulnerability to breach. The health data policymaking landscape of the next decade will feature a series of intractable conflicts between these important social values

    Bringing Citizens Back In: Renewing Public Service Regulation

    Get PDF
    This essay concerns the ways in which public services – particularly household services such as communications, energy, water and transportation – have been regulated and deregulated, and analyses what consequences this has for users and citizens. Much of the deregulation of public services from the 1980s – liberalization, privatization and New Public Management – was justified by claims that reform would provide users with more choice, whilst they would receive cheaper and better quality services. Little account was taken of the fact that users are highly heterogeneous, that socio-economic differences might be important in determining their consumption of public services, and that this may not lead to socially optimum outcomes. By examining consumption patterns in two large European countries, Spain and the UK, through an analysis of revealed and declared preferences, this paper sheds light on how socio-economic differences among households help determine public service consumption. The main findings are that the supposed benefits of public service deregulation are not evenly spread across populations, and that specifically targeted “bottom-up” regulation from the demand-side could usefully address these issues, thus improving social welfare.Regulation, Privatization, Public Services, Telecommunications, Electricity, Gas and water

    Piloting mobile mixed reality simulation in paramedic distance education

    Get PDF
    New pedagogical methods delivered through mobile mixed reality (via a user-supplied mobile phone incorporating 3d printing and augmented reality) are becoming possible in distance education, shifting pedagogy from 2D images, words and videos to interactive simulations and immersive mobile skill training environments. This paper presents insights from the implementation and testing of a mobile mixed reality intervention in an Australian distance paramedic science classroom. The context of this mobile simulation study is skills acquisition in airways management focusing on direct laryngoscopy with foreign body removal. The intervention aims to assist distance education learners in practicing skills prior to attending mandatory residential schools and helps build a baseline equality between those students that study face to face and those at a distance. Outcomes from the pilot study showed improvements in several key performance indicators in the distance learners, but also demonstrated problems to overcome in the pedagogical method

    Delivering Live Multimedia Streams to Mobile Hosts in a Wireless Internet with Multiple Content Aggregators

    Get PDF
    We consider the distribution of channels of live multimedia content (e.g., radio or TV broadcasts) via multiple content aggregators. In our work, an aggregator receives channels from content sources and redistributes them to a potentially large number of mobile hosts. Each aggregator can offer a channel in various configurations to cater for different wireless links, mobile hosts, and user preferences. As a result, a mobile host can generally choose from different configurations of the same channel offered by multiple alternative aggregators, which may be available through different interfaces (e.g., in a hotspot). A mobile host may need to handoff to another aggregator once it receives a channel. To prevent service disruption, a mobile host may for instance need to handoff to another aggregator when it leaves the subnets that make up its current aggregatorïżœs service area (e.g., a hotspot or a cellular network).\ud In this paper, we present the design of a system that enables (multi-homed) mobile hosts to seamlessly handoff from one aggregator to another so that they can continue to receive a channel wherever they go. We concentrate on handoffs between aggregators as a result of a mobile host crossing a subnet boundary. As part of the system, we discuss a lightweight application-level protocol that enables mobile hosts to select the aggregator that provides the ïżœbestïżœ configuration of a channel. The protocol comes into play when a mobile host begins to receive a channel and when it crosses a subnet boundary while receiving the channel. We show how our protocol can be implemented using the standard IETF session control and description protocols SIP and SDP. The implementation combines SIP and SDPïżœs offer-answer model in a novel way

    Security Issues in Mobile Payment from the Customer Viewpoint

    The perception of mobile payment procedures’ security by the customer is one major factor for the market breakthrough of the according systems. In this paper we examine security issues in mobile payment from the viewpoint of customers. Based on theoretical research we analyze empirical data from the MP2 mobile payment study with 8295 respondents in order to develop a set of dimensions, categories and aspects. The results do have a scientific as well as a practical impact: They provide a basis for the selection of appropriate indicators for further empirical studies. Furthermore they can serve as a guideline for mobile payment service providers in order to prevent security concerns through appropriate design and communication of payment procedures and to convince customers of the security of their mobile procedures by meeting concerns in informative advertising.
