Processi di accumulazione e degrado del “capitale intellettuale” nel governo dello sviluppo aziendale Una prospettiva basata sulla dinamica delle ris…

2012

Sempre più spesso oggi le fonti del vantaggio competitivo dell’impresa non risiedono in singoli fattori della produzione (sebbene disponibili in quantità limitata, difficilmente imitabili o sostituibili da parte dei concorrenti), quanto piuttosto nella capacità di saper individuare e mantenere un opportuno dimensionamento quali-quantitativo di risorse strategiche tangibili e intangibili. Tra queste ultime, il “capitale intellettuale” assume una particolare rilevanza. Per comprendere i meccanismi sottostanti all’acquisizione di un vantaggio competitivo sostenibile è necessario cogliere i processi dinamici di accumulazione e degrado del “capitale intellettuale” e delle altre risorse strategic…

Enhancing Waste Governance through Dynamic Performance Management. An analysis of the Sicilian Waste System.

Supporting Multi-Sided Platform firms to maintain rapid growth (and to avoid failure) over time through a Dynamic Business Modelling approach

2020

Over the last few decades, the diffusion of the sharing economy has nurtured continuous changes in business model opportunities with multi-sided platforms (MSPs) in many industries. MSPs are digital exchange platforms aiming at connecting unmatched demand- and supply- side participants through the use of internet technology. In many cases, such start-up initiatives have led to the creation of scale-up or high-growth firms (HGFs). However, in spite of the significant contribution to both economic development and employment, current studies seem to investigate primarily in an isolated perspective HGFs, MSPs and their business model innovation (BMI). The existing literature on HGFs focuses on …

Enhancing the Performance of Chinese High Education Institutions through Collaborative Governance: A Dynamic Performance Management Approach

2021

With the development of the knowledge economy, knowledge generation and application has been a powerful engine for economic development and global competition. Higher Education Institutions (HEIs) are under great pressure to improve their performance in teaching, research and the third mission, to respond to the changing social needs actively. This doctoral thesis is aimed at proposing a framework to enhance the performance of Chinese HEIs through collaborative governance using a dynamic performance management approach. Based on a literature review of performance management in Chinese HEIs, a conceptual framework is proposed to enhance the performance of teaching, research and the third mis…

Enhancing Joined-Up Government and Outcome-Based Performance Management through System Dynamics Modelling to Deal with Wicked Problems: the Case of S…

2015

The paper by Auping et al. (2015) focuses on the topic of societal 'ageing', that is, 'a population process, caused by declining fertility and mortality rates, which manifests itself in the growing number of older persons in society' (Huber, 2005). A broader definition frames societal ageing as a 'demographic, structural, cultural and economic transformation resultant from the increase in the number and proportion of " older " people within society' (Victor, 2005, p. 5). 'Double societal ageing' today characterizes most developed countries, which experience both an increase in the percentage of older people and in their life expectancy. In terms of public policy and finance, the relevance o…

Public Sector Applications of the System Dynamics Approach

2010

The article discusses various reports published within the issue, including one by Carmine Bianchi on understanding public sector from different levels and perspectives, one by Mauro Lo Tennero on the aspiration and structure of Sicily to enforce public policy, and one by Nuno Videira and colleagues on the use of group model building in the public sector to concur sustainable policies.

Fostering entrepreneurial learning processes through Dynamic Start-up business model simulators

2018

Abstract Entrepreneurial learning is a critical process in realizing the success or failure of a new business venture, as it implies that would-be entrepreneurs acquire those strategic management competencies required to start and manage a new business. Actually, statistics on start-up survival/failure rate reveal that the main reasons for failure are related to a lack of entrepreneurial competencies of start-uppers. This paper argues that combining Business Model representation schemas with System Dynamics modelling may support potential start-up entrepreneurs in learning and experimenting how to turn a business idea into a real firm. System Dynamics modelling is a methodology that allows …

A dynamic business modelling approach to design and experiment new business venture strategies

2018

Abstract Business Modelling has evolved as a key activity to reflect new business venture strategy by framing the way a firm will operate and how it will function in achieving its goals (e.g., profitability, growth, innovation, social impact). However, scholars and practitioners have criticized the adoption of a too static perspective in the design and use of conventional Business Model representations. Such a static perspective prevents nascent entrepreneurs experimenting with their Business Models and, as a result, identifying the most effective strategies, especially in terms of business sustainability and profitability. In this paper, we argue that combining conventional Business Model …

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…

A novel process-based model of microbial growth: self-inhibition in Saccharomyces cerevisiae aerobic fed-batch cultures

2015

Microbial population dynamics in bioreactors depend on both nutrients availability and changes in the growth environment. Research is still ongoing on the optimization of bioreactor yields focusing on the increase of the maximum achievable cell density. A new process-based model is proposed to describe the aerobic growth of Saccharomyces cerevisiae cultured on glucose as carbon and energy source. The model considers the main metabolic routes of glucose assimilation (fermentation to ethanol and respiration) and the occurrence of inhibition due to the accumulation of both ethanol and other self-produced toxic compounds in the medium. Model simulations reproduced data from classic and new expe…
