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…

Transforming food systems at local levels: using participatory system dynamics in an interactive manner to refine small-scale farmers’ mental models

2017

Food systems will need to undergo considerable transformation. To be better prepared for and resilient to uncertainty and disturbances in the future, resource users and managers need to further develop knowledge about the food and farming system, with its dominating feedback structures and complexities, and to test robust and integrated system-based solutions. This paper investigates how participatory system dynamics modeling can be adapted to groups at the community level with low or no formal educational background. The paper also analyses the refinement of workshop participants’ mental models as a consequence of a participatory system dynamics intervention. For this purpose, we ran two w…

Why do Traditional Performance Management Systems in Healthcare not always lead to Improved Performance? Outlining the Unintended Consequences of the…

2021

Researchers all around the globe have not yet come to an end as regards the supposed positive impact of traditional performance management systems in healthcare, and some research has shown that, paradoxically, performance management policies do not always lead to improved hospital performance. Despite the extensive research identifying the “pitfalls” of the NPM reforms around Europe and the unintended consequences for hospital staff and patients, little is known about the mechanisms that caused those negative effects, which essentially creates a research gap worth investigating. This PhD study tries to address this gap and show why do traditional PM Systems in healthcare not always lead to…

What Do Chinese Entrepreneurs Think about Entrepreneurship: A Case Study of Popular Essays on Zhisland

2020

Entrepreneurship is becoming increasingly essential in this current era of the knowledge economy. It contributes to the innovation of products and services as well as improved processes. In the long-run, it can also improve the sustainability of the economy by depicting better efficiency and social goals. To stimulate entrepreneurship, it is essential to investigate the thinking behind entrepreneurship or what entrepreneurs think about entrepreneurship. Such investigations should encompass the mental images of entrepreneurs. In this regard, content analysis, based on the popular Zhisland essays, may be applied to elicit opinions from Chinese entrepreneurs about activities, critical factors …

A model of goal dynamics in technology-based organizations

2011

The purpose of the present work is to build a suitable system dynamics model for goal dynamics in organizations, as proposed by Barlas and Yasarcan (2008). The proposed model does not bear any ambition of being exhaustive: the main objective of this paper is to propose a model of goal dynamics in which Goal Setting, Management by Objectives and Training are viewed as human resource practices able to enhance workers' goal commitment, and therefore, improve organizational performance. In the first part of this paper, an analysis of the Goal Setting Theory and the role of goal setting practices, in bettering worker's performance, are stressed. In the second part, a case-study, the causal loop …

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 …

“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…
