    Geographical analysis of the academic brain drain in Italy

    To study the behavior of Italian researchers living in Italy with a view to creating appropriate policies to tackle the brain drain and discourage academics from emigrating, we constructed a survey based on a sample of 4700 Italian researchers (assistant professors) in several universities in Italy. The outlook is far from rosy: Italian researchers are generally dissatisfied with the economic and social situation of the country. Strong family ties represent the element keeping them at home in Italy. In this regard, no particular differences were noted between the North and South of the country. In analyzing the Italian academic system we identified factors that have greater weight in driving Italian intellectual talent to emigrate: the country’s higher education system leaves all dissatisfied. Furthermore, we discovered other factors that, albeit weak, keep Italian researchers in Italy. However, one wonders how much longer family and national ties will be able to keep Italian skilled agents in Italy, and whether such dissatisfaction may jeopardize the country’s future economic development.Skilled migration; pull and push factors; academic system; geographical distribution

    We'll stay in touch: Intuitive communication means for social connectedness

    Get PDF
    One of the dominant aspects in people’s well-being is social connectedness. Social connectedness refers to the subjective awareness of being in close interpersonal, meaningful, and positive social relationships and social contexts (Tilburg et al., 1998; Perlman & Paplau 1981). In our research project we studied whether new services and high-tech products can help to increase connectedness between families (i.e. small community). A multidisciplinary approach is adopted in which technical and Human Factors knowledge are combined. The technology approach is strongly based on rapid prototyping, extending, reusing, and integrating existing devices and services in a novel, innovative way. Human Factors knowledge aims at user-centred design and evaluation of a.o. user experiences.\ud When people are forced to leave their home environment for a period of time, the lack of social connectedness might become predominant. This might lead to feelings of loneliness and have a negative effect on wellbeing. The focus in this project is on spinal cord lesion patients in a rehabilitation clinic, and their family members at home. Spinal cord lesion patients have to stay in the rehabilitation clinic up to one year after their accident or illness.\ud The project consists of three phases:\ud 1. Inventory of technology possibilities and restrictions, and user requirements;\ud 2. Technical probe study; one technical device is tested\ud 3. Pilot study; an integrated combination of technological devices and services is teste

    Requirements traceability in model-driven development: Applying model and transformation conformance

    Get PDF
    The variety of design artifacts (models) produced in a model-driven design process results in an intricate relationship between requirements and the various models. This paper proposes a methodological framework that simplifies management of this relationship, which helps in assessing the quality of models, realizations and transformation specifications. Our framework is a basis for understanding requirements traceability in model-driven development, as well as for the design of tools that support requirements traceability in model-driven development processes. We propose a notion of conformance between application models which reduces the effort needed for assessment activities. We discuss how this notion of conformance can be integrated with model transformations

    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 aggregator�s 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 �best� 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 SDP�s offer-answer model in a novel way
