Il paese viene presentato/raccontato attraverso lo sguardo dell'archeologo, del musicologo, dello storico, dell'urbanista, del linguista, della letteratura odeporica. Gli autori dei diversi saggi, racconti, testimonianze e foto sono studiosi o testimoni dalle solide competenze, molti sono colleghi di Roma Tre, che nel contribuire a questo volume hanno accettato la sfida o meglio il gioco di abbandonare il proprio linguaggio professionale e parlare in termini leggeri e scherzosi, adatti ad un pubblico di lettori, curioso e vivace, ma non di studiosi di Albania.

However, the ranking does not show whether a country is improving, worsening or is stable in its performance. Meanwhile, the evolutionary behaviour of a country’s performance is of fundamental importance to assess the effect of the adopted policies in both absolute and comparative terms. Nevertheless, establishing a general ranking among countries over time is an open problem in the literature. Consequently, this paper aims to analyze ranks’ dynamic by means of the functional data analysis approach. Specifically, countries’ performances are evaluated by taking into account both their ranking position and their evolutionary behaviour, and by considering two functional measures: the modified hypograph index and the weighted integrated first derivative. The latter are scalar measures that are able to reflect trajectories behaviours over time. Furthermore, a novel visualis...

Thus, an evolutionary well-being indicator is proposed by complement the original data with information concerning the first derivative. The second task is to provide an overall ranking of the countries over time using two functional tools: the area under the curve and functional depth, which return two distinct rankings. A simulation study is conducted to evaluate the effectiveness of the area in distinguishing groups of countries with different levels of well-being. The proposed method is employed on a real dataset concerning the human development index of European countries.

The reader will find a high standard scientific, multidisciplinary content in the form of short essays, testimonies, tales, poetry and much more. Also the images play an essential role, to supplement an experience hoped to be of refined and intellectual pleasure. This volume is the first of a series called Invitation to the journey.

On either tails, the information on the joint distribution of achievements or deprivations can be used to measure their concentration. In particular we suggest the use of Gini’s delta to measure concentration within a same tail - for different second order cut-off values k. We call this measure a measure of performance intensity. As an example we apply it to both tails of an OECD regional well-being performance indicator, and to the Multidimensional Poverty Index (MPI).

However a sometimes neglected collateral issue is how to take into account the joint distribution of the single components, and connected with this issue the question should be: how to compute the association among the single components of a multidimensional concept. This is precisely the aim of this paper. We suggest a counting based approach to detect positive association amongst the single components of multivariate phenomena, in particular among the best performing units and vice-versa among the worst performing units. Taking moves from Kendall's notion of concordance/agreement and from his well known concordance coefficient W (Kendall and Babington Smith in Ann Math Stat 10:275-287, 1939), we introduce the concept of local concordance and derive a local concordance coefficient and a local concordance curve. Our intent is to have, not an overall measure of concordance, i.e. not a global indicator, but instead local concordance coefficients to detect different degrees of concordance in the head, tail or centre of the multivariate distribution of the components of a well being indicator. The local concordance curve can have many different applications. When referred to the components of a well being indicator (and thus to inequality), the local concordance coefficient obtained from the first (last) window can be seen as a measure of concentration of high-level (or low-level) attributes. We apply this approach to exploit whether different aspects of social vulnerability are equally or unequally distributed among censuary areas of a same region.

In particular, making use of the same set of variables defined by the World Economic Forum we compute the composite indicator GCI by means of a structural equations model with endogenously derived weights. World Economic Forum, instead, defines GCI as a combinations of subindexes with weights that are fixed but vary according to the stage of development a country belongs to. The main issue we address is whether the weights of the subindexes change according to different stages of development.
