The interplay between residential location and cycling choice: the case of two metropolitan areas in Sardinia, Italy
Full text linkThe current paper aims to enrich the current understanding of the link between the choice of residential location, the propensity to cycle to work and the propensity to cycle for non-commuting purposes. To highlight the relationship among these choice dimensions we used a composite econometric model that allows for the joint modelling of multiple outcomes. Residential location and cycling propensities are modelled as a function of socio-demographic and level-of-service variables. The inclusion of common error terms allows us to control for self-selection and unobserved effects that can simultaneously influence the underlying propensities. The data for this study is drawn from a survey conducted in the metropolitan areas of Cagliari and Sassari (Sardinia, Italy) in 2016 among a sample of local employees. The sample comprises 2,128 observations. Our results indicate that a significant portion of unobserved variance between the residential location choice and the propensity to cycle for non-commuting reasons exists, suggesting the presence of a self-selection effect
The regional cycle network of Sardinia: upgrading the accessibility of rural areas through a comprehensive island-wide cycle network
Full text linkContext: Cycling is a climate-friendly means of transport that enables people to reduce their use of motorized transport and makes human settlements more inclusive and resilient. In Italy, the development of cycling has recently been boosted by the approval of Law no. 2/2018, which makes it compulsory for all Italian regions to draw up a regional cycling mobility plan.
Objective: To meet this regulatory provision, the Region of Sardinia approved the Regional Plan for Cycling Mobility in December 2018. Drawn up by the Sardinian Regional Transport Agency and the transportation research group of the University of Cagliari, the plan aims to lay out a regional cycle network to promote the use of the bicycle as a means of transport for both every day and tourist–recreational needs. One of the main objectives of the plan is to make the inland areas of the island more accessible, as the development of such areas tends to have been neglected compared to the coastal areas linked to seaside tourism. Hence, the plan intends to contribute to the increase of tourist flows into rural areas, which can be a strategic segment of local development.
Results: By analysing the methodology adopted to lay out Sardinia’s regional cycle network, the aim of the current paper is to show how the planning of an integrated cycle network in an island context can improve sustainable mobility and accessibility in the rural areas through which it passes. Furthermore, our analysis indicates that many rural settlements along the routes of the planned cycle network are sufficiently near each other for people to travel between them by bicycle.
Conclusions: Therefore, the cycling infrastructure could prompt a sustainable increase in the accessibility and connectivity of inland areas and stimulate the formation of clusters of small, interconnected towns and villages
The transformation of urban spaces as a cycling motivator: the case of Cagliari, Italy
Full text linkRecently walking and cycling, known as active mobility, have attracted the attention of both citizens and policymakers. Many new pedestrian areas and cycle paths have been created or extended in various cities across Europe and monetary incentives have been offered to support and encourage citizens to use active mobility. Starting from this context, the aim of the current paper is to evaluate the impact that interventions of re-functionalization of the street space have in boosting cycling mobility in the city of Cagliari (Italy). Employing data collected in three distinct cross-sectional surveys (2014, 2019 and 2020), we constructed a logit model that simulates individuals’ probability to cycle/not cycle for one purpose or another. Model results indicate a general increase in the probability to cycle over time and that individuals living in those areas where cycling facilities are provided were more likely to use the bicycle than the rest of the city’s residents. Furthermore, our findings show that measures developed to improve cycling infrastructure should be implemented jointly with interventions of urban regeneration, that modify the environment in terms of both safety and livability. Finally, our results stress the importance of the longitudinal assessment of policies and strategies
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
Towards a SDGs Based Neighborhood Sustainability Evaluation Framework: A Tool for Assessing Sustainability at the Urban Micro-Scale
No full textAppropriate 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
