Pattern di contrazione e dinamiche locali. Risorse di rete e opzioni di adattamento per i territori della Val Parma/Val d’Enza
No full textAll’interno del rinnovato dibattito sui temi della contrazione delle aree interne, il contributo intende proporre una riflessione sull’attività di ricerca in essere presso l’Università di Parma a partire dall’affinamento metodologico per lo studio di modelli interpretativi delle dinamiche di contrazione, in particolare nelle regioni del Nord Italia, per poi approfondire lo studio delle dinamiche locali nei territori appenninici parmensi e riflettere, alla luce dei pattern di contrazione precedentemente individuati, sull’effettiva capacità delle politiche regionali in essere di rilanciare questi territori, attenuarne gli evidenti squilibri territoriali e salvaguardarne le risorse specifiche territoriali, ponendo particolare attenzione alla gestione della risorsa paesaggio, quale capitale distintivo seppur fortemente a rischio.
Occasione per approfondire la conoscenza del territorio appenninico parmense è stata la collaborazione con l’Osservatorio regionale per la qualità del paesaggio (Regione Emilia-Romagna) nell’organizzazione del corso di formazione “Materia Paesaggio 2019”, avente a oggetto i territori della Val Parma e Val d’Enza. L’indispensabile apporto interdisciplinare degli attori locali coinvolti nell’esperienza ha aperto ulteriori riflessioni circa le possibili opzioni di adattamento alle criticità poste dall’abbandono, mediante l’attivazione di risorse di rete.
Il contributo sviluppa quindi una riflessione sia sullo stato di avanzamento della ricerca, sia sulle politiche in essere, al fine di riconsiderare modelli e procedure in grado di dare forma ad indirizzi e azioni più performanti
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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Measuring Pedestrian Accessibility to Public Transport in Urban Areas: a GIS-based Discretisation Approach
Full text linkThe paper presents a GIS-based approach that can help practitioners in assessing pedestrian accessibility in
urban areas, with a focus on accessibility to public transport stops and stations (nodes).
This methodology represents an attempt to set up integrated approaches to urban planning and mobility
planning, and provides a support in the decision-making process, with the dual aim of encouraging
sustainable and non-motorised mobility and of improving public transport attractiveness.
The proposed methodology is divided into three main steps:
1) Map the pedestrian permeability/impermeability of urban spaces around public transport nodes;
2) Discretisation of the map in a grid of 3m x 3m cells which attributes derive from the Topographic
Database informative layers (DBT), and application of an algorithm to calculate the pedestrian access time
to the public transport node;
3) Map of access times to create detailed pedestrian isochrones, and calculate how many residents (or how
many opportunities and facilities) in the neighbourhood are well served by the public transport system to
measure accessibility levels.
The approach is applied to the case study of some metro stations in the city of Brescia, focusing on the
different results obtained for the different urban forms that constitute the city (the modern city with open
urban forms, the historical city centre and a residential neighbourhood).
Finally, the paper provides a first comparison with similar results that can be obtained through vector-based
tools that create isochrones from the road graph (e.g. Network Analyst tools)
Criteria to Identify Streets to Be Pedestrianised Near Major Commercial Attractors: The Case Study of the San Benedetto Market in Cagliari (Italy)
No full textThe paper aligns with the debate on Smart and Sustainable Cities, as outlined by the Sustainable Development Goals (SDGs), with a focus on pedestrianisation and accessibility. It introduces a framework aimed at pedestrianising streets near significant attractors to reclaim car-free public spaces for local communities. Beyond social benefits, the study explores the environmental, economic and health advantages. The research incorporates a comprehensive set of criteria for selecting streets, focusing on functions and streets that are seamlessly compatible to ensure a smooth transition. Criteria, both qualitative and quantitative, were determined after a thorough literature review. These include mobility, land use, accessibility, pavement amenities, street connectivity, safety and security and streetscape design. The research seeks to confirm the potential pedestrianisation of streets close to San Benedetto Market in Cagliari, in accordance with the city administration's objectives. The proposed criteria optimise traffic flow while fostering vibrant pedestrian spaces and enhancing urban accessibility. Preliminary findings demonstrate the beneficial impact of the methodology, including inclusive areas, and enhanced accessibility. The research aims to confirm the feasibility and usability of pedestrianisation, determining whether a measurable method is more effective than a case-by-case approach. The expected results will contribute to understanding the realisability and employability of pedestrianisation, providing valuable insights for administrations. The criteria could serve as a practical tool, offering a systematic and efficient approach useful for urban planners and policy makers to improve traffic management, foster sustainable urban development and interesting pedestrian environments and contribute to a more inclusive and socially connected urban area
Enhancing Public Space Accessibility and Inclusivity in Residential Neighbourhoods: A Methodological Framework and Pilot Application
Full text linkThe paper adds to the debate on urban transformation, which plays a significant role in improving quality of urban life and liveability of public spaces, as also stated in UN Sustainable Development Goal No. 11. The research aims to test a methodology for identifying an abacus of urban regeneration interventions to enhance attractive and critical nodes through accessibility and inclusivity. The quality of the system of connections between polarities, the promotion of active mobility, zero soil consumption and the renaturalisation of urban spaces are fundamental criteria to define urban regeneration solutions. The proposed approach develops on two levels: a GIS-based spatial analysis of urban data and a participatory process. The innovative planning process is tested on the San Leonardo neighbourhood in the Municipality of Parma, Italy, which allows us to verify the potentials and limitations of the procedure, identifying future work perspectives. Moreover, the application allows us to check the replicability in other urban contexts, possibly envisaging other applications to more case studies. Our results consist of the identification of the vocations and the critical aspects of nodes and axes to regenerate urban space in medium-sized and large cities' suburbs
