Fiscalità urbanistica e consumo di suolo
No full textLo scopo di questo contributo è quello di presentare alcuni dati volti a quantificare la dispersione urbana, a dare un’interpretazione economica di tale fenomeno anche alla luce del ruolo della fiscalità urbanistica. A questo scopo, si offre dapprima una panoramica delle determinanti economiche sottostanti il fenomeno e successivamente si presentano alcuni dati volti a misurare direttamente ed indirettamente il consumo di suolo. Si analizzano poi le caratteristiche dei contributi di costruzione nel sistema di finanziamento dei Comuni italiani in collegamento con i possibili incentivi da questi prodotti a un eccessivo consumo di suolo. Infine, si illustrano alcuni indirizzi di politica del territorio
Environmental Awareness and Rail Passenger Transport in Europe
No full textIn recent decades, several articles have emphasised the need for a sustainable society, and hence for sustainable development. Identifying policies that will result in a sustainable transportation network is a major challenge for policy makers, because it involves a high level of complexity.
A contribution can be made within this ‘complex’ framework by gathering knowledge on current transport development and forecasting future trends. For example, simulations on future scenarios show that the energy consumption in 2030 will certainly favour the ‘train’ mode in both urban and long distance transport. In this regard, it would be interesting to identify which European countries are already shifting to the rail mode, and are thus directed towards more sustainable transport development.
An attempt in this direction will be made by this study, aiming to outline the current relationship between environmental and rail performance in Europe. In this context, a simple descriptive analysis will show how a robust relationship between environmental awareness and transport mode choice cannot be detected, although it seems that the larger the share of rail transport, the better the quality of the urban environment.
In addition, a multicriteria analysis was performed to draw up a ranking of twenty-five European countries on the basis of indicators concerning environmental awareness and rail performance. The results show essentially that a group of North-Central and Eastern European countries (Netherlands, Belgium, Denmark, United Kingdom, Czech Republic, Poland and Slovenia) seem to have high environmental awareness and good rail transport utilization, whilst a group of other countries (Latvia, Estonia, Lithuania) displays low values according to these two main profiles. It is likely that these latter countries suffer less from environmental problems owing to their low values in GDP and in transport network in general.
These results are indeed indicative, although more data and indicators would be necessary. However, the results highlight – in principle – the need for policy-makers to adopt different ‘sustainable’ policies for different ‘country topologies’ in order to tackle the above-outlined ‘complexity task’ above more effectively

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
La facciata nell’era digitale: autonoma e ‘su misura’
No full textAlready in 1993 in Last Apple, Koolhaas stated that buildings, due to their size and complexity, were no longer the result of a unified design and the façade was becoming an autonomous, stand-alone project. A year later, in Bigness, Koolhaas added that the modern dream of 'correspondence between interior and exterior' was over and architectural design had to draw on the skills of diverse professionals and teams of specialists, supplanting the traditional set-up of architectural firms. Today, his intuition has become true: the effects of the digital technological revolution have increased and showed itself most clearly in the treatment of façades that are media, kinetic and reactive. The morphology of the façade is now variable and its design can be the work of engineering and architecture companies or specialised firms that tailor it to the designer, as has been the case up to now with the calculation of structures
