Gaming as a Key Approach for the Recovery Process of a Public Space: The Case Study of the Old Chemical Plant ‘Chimica Arenella’ in Palermo
2021
This poster describes the FORGE (FactOry of uRban GamEs) project, a proposal that our research group launched in partnership with the Municipality of Palermo (Italy) and other local stakeholders in 2019. FORGE will be hosted in what was previously a chemical plant (the former 'Chimica Arenella') and is an open factory designed to collect needs and to generate interventions for urban innovation. The four key terms we have used for the project are urban, game, factory and participation. In fact, FORGE employs a participatory methodological model based on the concept of game, aimed at supporting social and economic development through a platform for participatory co-design. FORGE plays also a …
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. …
Pareto or log-normal? Best fit and truncation in the distribution of all cities
2015
In the literature, the distribution of city size is a controversial issue with two common contenders: the Pareto and the log-normal. While the first is most accredited when the distribution is truncated above a certain threshold, the latter is usually considered a better representation for the untruncated distribution of all cities. In this paper, we reassess the empirical evidence on the best-fitting distribution in relation to the truncation point issue. Specifically, we provide a comparison among four recently proposed approaches and alternative definitions of U.S. cities. Our results highlight the importance to look at issue of the best-fitting distribution together with the truncation …
Organised Crime and the Economy: a Framework for Policy Prescriptions
2014
In this paper we discuss policies to combat organised crime from the perspective of economic analysis. We introduce concepts such as supply and demand for Mafia and the implied notion of equilibrium to build a framework to classify the contexts in which organised crime interferes with the economy. We then use this framework to discuss policy interventions, distinguishing between policies implemented by the State and mobilisation of civil society. We show that using the economic approach helps understand the aspect of persistence of criminal organisations and identify vicious circles of different nature. The broad spectrum of State policies identified includes norms on competition, on the ef…
On the limits to the long-period method in classical economics. A note
2001
On a first reading of Theory of Production, Kurz & Salvadori (1995) appear to confine the empirical domain of the long-period models of the classical theory of value and distribution to stationary economies with non-constant returns to scale and to growing economies with constant returns to scale. Such a reading is shown to be untenable since it merges the two levels of exploring the extension of a model and of testing a theoretical hypothesis. Conversely, the way Kurz & Salvadori tackle the problems of price dynamics and returns to scale in growing economies is shown to be compatible with what appears to be Sraffa's (implicit) strategy of research.
Recursive partitioning: an approach based on the weighted kemeny distance
2015
In the framework of preference rankings, the interest can lie in finding which predictors and which interactions are able to explain the observed preference structures. The possibility to derive consensus measures using a classification tree represents a novelty and an important tool, given its easy interpretability. This work proposes the use of a univariate decision tree for ranking data based on the weighted Kemeny distance. The performance of the methodology will be shown by using a real dataset about university rankings.
I vincoli organizzativi alla formazione dei sistemi turistici locali: i Club di prodotto
2010
Agli inizi dello sviluppo del turismo, fare turismo significava essenzialmente trasferirsi per un periodo di tempo più o meno lungo non superiore ad un anno in un luogo diverso da quello da quello abituale e soddisfare l’esigenza in un luogo gradevole e funzionale e con poche esigenze essenziali (fare il bagno al mare, passeggiare in un luogo diverso dall’abituale, sciare in montagna, ecc.). Oggi nel fare turismo è sempre più importante il “cosa fare” e il “come farlo” e la località tende quindi ad essere valutata e prescelta in ragione della capacità di garantire una soddisfazione turistica non solo attrattiva, che convince il turista a muoversi verso di essa, ma occorre garantire servizi,…
An Extension of the DgLARS Method to High-Dimensional Relative Risk Regression Models
2020
In recent years, clinical studies, where patients are routinely screened for many genomic features, are becoming more common. The general aim of such studies is to find genomic signatures useful for treatment decisions and the development of new treatments. However, genomic data are typically noisy and high dimensional, not rarely outstripping the number of patients included in the study. For this reason, sparse estimators are usually used in the study of high-dimensional survival data. In this paper, we propose an extension of the differential geometric least angle regression method to high-dimensional relative risk regression models.
Inequalities in Consumption Patterns over the Life Cycle and during the Great Recession
2015
The aim of the study is to analyse the relationship between recession, population structure and consumption behaviour over the life cycle. To this aim, we consider three clusters of non-durable expenditures such as food at home, work-related and core expenditures. The analysis has been performed on micro data on the Household Budgets for the period 1997-2013. Based on life cycle theory, two statistical models has been estimated, viz. a pre-crisis (1997-2007) and a great recession period (2008-2013) model. The study shows that the recession has entailed a reduction of the average expenditure for each category of consumption, and the intensity of the reduction is different among households an…
Life satisfaction and tax morale: The role of trust in government and cultural orientation
2022
Taxes are essential for a government to function correctly, because they fund public services and promote long-term growth in a country. Tax morale is a positive attitude toward taxation shaped by extrinsic and intrinsic motivations, including numerous psychological factors. However, these factors are far from completely clear and a better understanding of what drives tax morale can greatly help governments in the design of tax policies and their administration. In this paper we test the novel hypothesis that life satisfaction is one of the psychological aspects affecting tax morale. Using longitudinal data from the World Value Survey, we show that people more satisfied with their own life …
