Innovating business processes in public administrations: towards a systemic approach

2020

PurposeThe purpose of this paper is to study the credit collection process in public administrations in order to develop a conceptual model which goes beyond the traditional logic of linearity, adopting system thinking approaches.Design/methodology/approachThis study analyses the case of an Italian local government-owned enterprise. Data collection through semi-structured interviews and document analysis has enabled the development of propositions, the identification of systemic variables, and the development of an explanatory modeling process based on the system dynamics approach.FindingsThis paper shows that public administrations can effectively involve external actors, especially citize…

Framing Caesarean Section Reduction Policies Through a Dynamic Performance Management Approach: A Maternity Pathway Case-Based Analysis

2017

The World Health Organization since the last three decades strongly encourages countries to reduce the caesarean section (CS) rate down to 10–15%. However, this goal nowadays appears still far from its achievement. Public decision-makers are indeed struggling to design and implement effective policies to reduce the CS rate. The literature provides a wide range of factors causing a change in the CS rate, such as the patient clinical profile and the healthcare service quality provided. Maternity pathway (MP) is considered a mean through which to standardize the cares and to reduce CSs. This study investigates the MP recently introduced in Sicilian local health authorities. Based on such an an…

Fostering Collaborative Governance in Chronic Disease Management Programs: A Dynamic Performance Management Approach

2020

Chronic diseases are the leading cause of disability and mortality in the world and represent a global health emergency due to the increase in frequency and complexity that has been occurring in recent years. The outcomes related to chronic care needs depend on the joint effort of a multi-provider, multi-disciplinary, and multi-professional service network, which operates along a clinical pathway. However, all the different players involved in the provision of services may have different interests and goals derived from their organizational structure and their role in the overall health system. This context of fragmented governance makes performance management of care services problematic. …

Evolution of a Non-Hermitian Quantum Single-Molecule Junction at Constant Temperature

2021

This work concerns the theoretical description of the quantum dynamics of molecular junctions with thermal fluctuations and probability losses. To this end, we propose a theory for describing non-Hermitian quantum systems embedded in constant-temperature environments. Along the lines discussed in [A. Sergi et al., Symmetry 10 518 (2018)], we adopt the operator-valued Wigner formulation of quantum mechanics (wherein the density matrix depends on the points of the Wigner phase space associated to the system) and derive a non-linear equation of motion. Moreover, we introduce a model for a non-Hermitian quantum single-molecule junction (nHQSMJ). In this model the leads are mapped to a tunneling…

POLICY INNOVATION AND IMPLEMENTATION IN PUBLIC SECTOR: COMPLEXITIES, DYNAMICS AND UNCERTAINTIES

This research is expected to contribute to the knowledge base on how an effective impact assessment and adoption of innovations in the public sector could be facilitated. The need for trans-disciplinary assessment of the long-term potential impacts of innovation-driven policies may well be met with system dynamics as part of the dynamic performance management approach by way of modelling based simulation and analysis. Moreover, such analysis may contribute to learning and the accumulation of a knowledge repository that enables strategy developers, policy designers and decision makers to arrive at unexpected (often called counterintuitive) conclusions prior to policy implementation. Such ins…

On the Non-Intrusive Load Monitoring in dwellings: a feasibility perspective

2021

The oncoming modernization process of the power grids, driven above all by decarbonisation objectives and the continuous improvement of digital technologies, is encouraging active participation in the electricity market by consumers through the Demand-Response mechanism. From this perspective, the introduction of smart meters and energy consumption monitoring devices plays a fundamental role, being able to give benefits to consumers, suppliers and the electricity grid itself. This paper proposes a supervised method of non-intrusive load monitoring (NILM) based on the recognition of patterns in the time domain with the Dynamic Time Warping algorithm which is suitable for low-cost smart meter…

E-Government's Role in Shifting the Paradigm of Performance in the Public Sector

2015

The emergence of e-government changed the world of the Public Administration (PA) and the discipline of Public Management dramatically. Through the presentation of a case- study of the municipality of Palermo, this article attempts to discuss the renewed need for assessing performance of e-government services in a local government and to disclose the main critical issues in accomplishing this evaluation. Palermo is experiencing the implementation of a second- generation e-government project that is embodied in the realization of a web portal. The conceptualization of a framework to assess the performance of the digital services appears to be crucial in order to improve the system and to avo…

An optimized system dynamics approach for a hotel chain management

2009

The proposed model consists of an integrated system dynamics-data envelopment analysis approach to value, in a dynamic framework, the effects over time of the policies implemented according to the relative efficiency analysis. Rooms’ price and competing facilities (the hedonics) are the decision variables to move in order to push the hotels towards a higher relative efficiency at the end of the observation periods. In fact, in competitive markets as tourism, hotels compete for money offering differentiated quality. Moreover, according to the microeconomic theory, a producer of differentiated goods is not a price taker but a price maker. Therefore, we assume that the decision maker of the ho…

Impact of COVID-19 on the travel and tourism industry.

2021

Abstract Our paper is among the first to measure the potential effects of the COVID-19 pandemic on the tourism industry. Using panel structural vector auto-regression (PSVAR) (Pedroni, 2013) on data from 1995 to 2019 in 185 countries and system dynamic modeling (real-time data parameters connected to COVID-19), we estimate the impact of the pandemic crisis on the tourism industry worldwide. Past pandemic crises operated mostly through idiosyncratic shocks' channels, exposing domestic tourism sectors to large adverse shocks. Once domestic shocks perished (zero infection cases), inbound arrivals revived immediately. The COVID-19 pandemic, however, is different; and recovery of the tourism ind…
