A dynamic simulation approach to frame drivers and implications of corruption practices on firm performance
2014
Corruption is a multifaceted socio-economic phenomenon widely spread - although with different intensity - all around the world. Many studies on corruption have been conducted at a country-level, but relatively little effort has been placed in evaluating its implications, in terms of both financial and competitive performance, at a firm-level. Therefore, this paper aims at exploring the causal relationships underlying the effect of corruption on firm performance in order to show the different scenarios that may emerge from the combination between external (i.e., contextual conditions) and internal (i.e., organizational characteristics) forces that drive corruption. To this end, we adopt a D…
The determinants and barriers of e-Government Adoption in the Municipality of Palermo
2014
La costante innovazione tecnologica fornisce nuovi spunti per la creazione di network efficienti e lo sviluppo di nuovi business. Anche la Pubblica Amministrazione (PA) vuole sfruttare tali opportunità. In particolare, la PA, attraverso l’implementazione di una strategia di e-Government può mirare a una maggiore efficienza, alla riduzione dell’errore umano e delle frodi. Tuttavia, non si tratta di un mero cambiamento di strumenti. Il passaggio a un’Amministrazione Digitale richiede un cambio di approccio manageriale. Partendo dalla somministrazione di un questionario (sul sito istituzionale del Comune di Palermo, 389 risposte utili) che ha confermato la poca consapevolezza dei cittadini rig…
“Dealing With Patients’ Mobility Issues: An Inter-Institutional Perspective To Analyze The Phenomenon And To Support Sustainable Policy Making In Sic…
2014
Nowadays many Italian policy makers, both at a national and regional level, are devoting a growing attention to the phenomenon of patients’ movements seeking public healthcare treatments out of the territorial jurisdiction. This paper presents the main features of a research project being carried out to analyze the mobility flows of Sicilian patients towards other Italian Regions in order to support the design of sustainable related policies. Such study adopts an inter-institutional perspective as the design of sustainable mobility-related policies requires a coordination effort of the Regional Healthcare Department, the Local Health Authorities and the Healthcare providers. The main outcom…
Grid-Following and Grid-Forming MODELS in ATP-EMTP for Power Systems Simulation
2022
The paper presents the models of grid-following and grid-forming converters in the software ATP-EMTP for power systems simulation. The models are developed using the MODELS language, they are described in details discussing all issues and aspects related to the implementation, and they are also shared as open source models. The models are validated with a simulation-based approach, comparing the results with the models developed in MATLAB/Simulink and in NEPLAN, considering both the phasor RMS and EMT time domains, and thus performing a comprehensive cross-platform and cross-domain validation. In line with the spirit of the ATP software and community, the models of grid-following and grid-f…
PUBLIC POLICY PLANNING TO ENHANCE THE RESILIENCE OF SOCIO-ECOLOGICAL SYSTEMS TO CLIMATE CHANGE: OPERATIONALIZING RESILIENCE CONCEPTS FROM A DYNAMIC P…
This study outlines a system dynamic based approach to the planning for resilience in food systems to climate change. The processes described and the insights gained are novel in the literature since they focus on describing operational aspects of resilience that can be generalized to multiple contexts and problems. On the one hand, the process described offers an aid for researchers and practitioners operationalizing resilience in public sector settings. Simultaneously, the insights gained from multiple stakeholder discussions and modelling work open new questions regarding the general mechanisms driving resilience in food systems. Climate change is threatening the extent to which social, …
The Retirement and Early Retirement in Italy: a System Dynamics approach
2006
The main aim of this study is underline that System Dynamics approach allows the building of a general framework in which psychological, economic, social, legal and organizational variables converge to describe the retirement behaviour and its main unintended consequences. It’s emphasized that organizational commitment and psychological contract breach play a considerable role in the dynamics of retirement behaviour. In the first part of this paper, an analysis of main contributions in the retirement and early retirement fields is outlined. Further, the psychological, social, economical and legal approach to retirement behaviour is also briefly remarked. In the second part, retirement pheno…
Il dynamic business model: una prospettiva dinamica per la progettazione dei modelli di business
2017
Building on the extant literature on business modelling and focussing on start-up firms, this article aims at exploring the combination between conventional business model schemes and System Dynamics methodology with the intent to overcome those limitations related to a static design approach. By mapping the multiple key elements underlying value creation processes – linked according to a cause-and-effect perspective – and with the support of a simulation-based methodology, entrepreneurs may experiment and understand how the firm reacts to strategic and organizational changes in terms of performance, innovation and value creation.
Crowdsourcing as a mode of open innovation: Exploring drivers of success of a multisided platform through system dynamics modelling
2020
This article aims to explore drivers of success of a crowdsourcing platform. The study conceptualizes crowdsourcing as a mode of open innovation and places such a concept within the context of the sharing economy. Upon this framework, the paper analyses the case of InnoCentive, a successful crowdsourcing platform where innovation-driven organizations search for solutions to their R&D tasks. The system dynamics model frames main InnoCentive business processes and offers a causal perspective on the relationships between platform performance—in terms of users base—and resources structure. The discussion on simulation outputs is carried out through a dynamic performance management view of p…
