Neural Multimodal Belief Tracker with Adaptive Attention for Dialogue Systems

2019

Multimodal dialogue systems are attracting increasing attention with a more natural and informative way for human-computer interaction. As one of its core components, the belief tracker estimates the user's goal at each step of the dialogue and provides a direct way to validate the ability of dialogue understanding. However, existing studies on belief trackers are largely limited to textual modality, which cannot be easily extended to capture the rich semantics in multimodal systems such as those with product images. For example, in fashion domain, the visual appearance of clothes play a crucial role in understanding the user's intention. In this case, the existing belief trackers may fail …

THE PUBLIC HOSPITAL AS A SYSTEM: FINANCING POLICIES AND THEIR LONG-TERM IMPACT ON THE HEALTH SERVICES PROVIDED

Σκοπός: Οι νέες πολιτικές χρηματοδότησης που υιοθετήθηκαν κατά την περίοδο της οικονομικής ύφεσης συνέβαλαν αναμφισβήτητα στη μείωση των δαπανών του νοσοκομείου, αλλά φαίνεται να είχαν αρνητικό αντίκτυπο για τους ασθενείς και τους εργαζομένους των νοσοκομείων (Economou, Kaitelidou, Karanikolos, & Maresso, 2017; Keramidou & Triantafyllopoulos, 2018; Mitropoulos, Vasileiou, & Mitropoulos, 2018; OECD & European Observatory on Health Systems and Policies, 2019). Η παρούσα ποιοτική μελέτη χρησιμοποιεί τη μέθοδο των δυναμικών συστημάτων (system dynamics) για να αναλύσει και να εξηγήσει τα μακροπρόθεσμα αποτελέσματα των πολιτικών αυτών. Υλικό-Μέθοδος: Δημιουργήθηκε ένα ποιοτικό μον…

“Toward a full decentralization of public regional healthcare systems: an exploratory system dynamic approach to evaluate some socio-economic healthc…

2012

The Italian Healthcare Service, originally managed by the central Government, has been gradually adjusted toward a decentralized model, with ample devolution of legislative, organizational and financial competencies to the regions, now responsible for the creation of an institutional framework where efficiency, efficacy and accountability have to inform the actions of the healthcare operators. In Sicily for decades those principles seem not to have received practical implementation, as the healthcare system has been chronically marked by unsatisfying social and economic performances. Due to the recent financial disequilibria, the central Government pushed the regional one to reform the enti…
