Cruise passengers' expenditure at destinations: Review of survey techniques and data collection

2020

Spending by cruise passengers constitutes an important contribution to the economy of destinations. The issues related to the analysis of the expenditure have been widely debated for many years both in the scientific literature and in the common political debate. Despite 20 years of empirical research on this topic, not consolidated quantification methods exist to inform the debate. This work offers a brief review of the principal research on cruise tourist spending. It analyses the main characteristics of the surveys, reviews the different methods and techniques employed as well as assesses the main results. The article concludes with a discussion of the studies conducted and identifies fu…

Population geocoding for healthcare management. Technical challenges and quality issues

2015

The present work aims at describing the main issues related with population geocoding for healthcare management. Some of the available procedures for geocoding multiple addresses are described and an indicator of quality of the geocoded addresses is proposed. As a case study, the geocoding of population addresses of a set of 9 Sicilian Municipalities is described and results deriving from the use of two different methods are compared in terms of quality. Some potential applications of population geocoding in healthcare management are finally discussed.

Colonies

2015

The entry discusses David Ricardo's three main analytical arguments related to the colonial issue: i) colonies as a source of new fertile land and therefore as a viable solution to the problem of decreasing returns on domestic land; ii) colonies as possible outlet markets able to absorb domestic excess supply; and, finally, iii) the effects of trade restrictions between a colony and its mother country.

Defense versus Opulence? An Appraisal of the Malthus-Ricardo 1815 Controversy on the Corn Laws

2015

This article proposes a rational reconstruction of the arguments of Malthus and Ricardo in their 1815 essays, Grounds of an Opinion and An Essay on Profits, whereby a policy of free corn trade was repudiated and endorsed, respectively. Malthus envisaged defense and (trade-induced) opulence as two mutually alternative options and, if required to make a choice, he had no hesitation in choosing the former. By contrast, Ricardo excluded any such trade-off, arguing that even in the case of war or poor domestic harvest, foreign agricultural countries would be seriously damaged if they opted for restrictions on their corn exports to Great Britain.

Systems Thinking and Sustainability in Organisations

2015

This set of articles arises from a series of conferences (Business Systems Laboratory Symposia, 2013-2015) and in particular from the 2nd Business systems Laboratory International Symposium, Rome 2014 with the theme ‘Systems Thinking for a Sustainable Economy’, concerned with systems thinking and its relations with sustainable management, where the relevance of systems thinking was demonstrated. The current period of our global society is characterised by intense transformations in the competitive logics of organisations, markets, and, generally speaking, society. Social circumstances today are typified by dynamism, connectivity, nonlinearity, and emergent properties — in other words by ‘co…

An analysis of Italian university students' performance through segmented regression models: gender differences in STEM courses

2021

AbstractThis paper investigates gender differences in university performances in Science, Technology, Engineering and Mathematics (STEM) courses in Italy, proposing a novel application through the segmented regression models. The analysis concerns freshmen students enrolled at a 3-year STEM degree in Italian universities in the last decade, with a focus on the relationship between the number of university credits earned during the first year (a good predictor of the regularity of the career) and the probability of getting the bachelor degree within 4 years. Data is provided by the Italian Ministry of University and Research (MIUR). Our analysis confirms that first-year performance is strong…

Space-Time FPCA Clustering of Multidimensional Curves.

2018

In this paper we focus on finding clusters of multidimensional curves with spatio-temporal structure, applying a variant of a k-means algorithm based on the principal component rotation of data. The main advantage of this approach is to combine the clustering functional analysis of the multidimensional data, with smoothing methods based on generalized additive models, that cope with both the spatial and the temporal variability, and with functional principal components that takes into account the dependency between the curves.

Socio-economic deprivation, territorial inequalities and mortality for cardiovascular diseases in Sicily

2016

The present work aims at analyzing the relationship among deprivation, distance from the nearest hospital and mortality for cardiovascular diseases in Sicily. Data derived from 2011 Census are used for the determination of the deprivation index at the municipality level, whereas distance from the municipality of residence and the nearest municipality with at least one hospital is considered in terms of travel time. Results highlight association between socio-economic conditions and mortality for cardiovascular diseases, whereas it seems that the distance from the hospital is only poorly associated with mortality.
