Planning and Designing a Sustainable Mobility System in Rural Areas
No full textSustainable transportation planning and design play a vibrant role in the transformation of the transport sector to become more environmentally friendly. Sustainable mobility in cities is a widely debated topic, but there is a lack of research and perspectives on sustainable mobility in rural areas. The aim of this paper is to provide an overview and critical analysis of recent studies on sustainable mobility in rural areas in Europe. From the selected studies, we highlight possible solutions for a more sustainable transport system in marginal territories, which could support decision-making processes. The paper consists of two parts. The first part is a preliminary analysis of the concept of sustainable mobility, and the second part is a critical analysis of best practices. The analysis highlights relevant aspects to consider when planning and designing transport solutions in rural areas. Particularly, we notice a growing attention to citizens’ participation and engagement, which often becomes a decisive factor in achieving shared and efficient solutions. Also, the analyzed sustainable mobility systems show that the fragile population, especially elderly people, can considerably benefit from shared mobility solutions in rural areas, as they substantially increase their possibility of accessing services and infrastructure. The best practices are further divided into four categories: micromobility, mobility as a service (MaaS), transport on demand, and shared mobility. From the critical comparison of the analyzed best practices, we conclude that transport problems in rural areas can be more efficiently addressed with alternative solutions other than traditional public transport modes. This aspect will be further evaluated in the follow-up of the research, funded within the PON Program of the Italian Ministry of University and Research, in the Marche Region of Italy, as an assessment of the design and planning of a sustainable mobility strategy in rural areas
Artificial Intelligence enabled performance evaluation of distribution networks under high penetration of Renewable Distributed Generation and Electric Vehicles
No full textThis work is supported by the Effat University under the grant number (UC#9/12June2023/7.1-21(4)7)The present investigation utilizes the Forward-Backward Sweep (FBS) technique in combination with the Sea Horse Optimization (SHO) algorithm to maximize the distribution network's capacity and arrange Distributed Generators (DGs) according to their intended use case. Through the use of Torrit software and the integration of MATPOWER toolbox in MATLAB, the network is methodically assessed under four scenarios (Case A to Case D), featuring four DG types (type 1, type 2, type 3, and type 4). The most promising of them is Case C, which uses type 3 DGs and shows impressive reductions in reactive and active power loss along with a significant increase in power factor and voltage profile. The conclusions provide utility operators looking for the best DG deployment tactics with insightful information.Effat Universit
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
Exploring Mobility in Rural Areas. A Case Study in the Marche Region’s Central Apennine
No full textThis study investigates the critical role of rural mobility in combating the risk of rural abandonment and facilitating the re-population of the pilot inner area of the Marche Region, Italy, for the Italian National Strategy for Inner Areas (SNAI). The research delves into the primary reasons behind residents’ mobility, including daily needs, socializing, work, and leisure, spanning municipalities and nearby urban areas. Using qualitative and quantitative methods alongside tools like QGIS, Komoot, Moovit, TomTom, and Python, the study aims for a thorough analysis and evaluation of current mobility patterns. It seeks to reveal detailed insights into travel behaviors, including off-peak private vehicle usage, peak travel times, and trip lengths, with the goal of highlighting critical conditions and potential opportunities for redevelopment strategies. Ultimately, the study aims to contribute to evaluating the region's transportation infrastructure and identifying areas for improvement. Furthermore, it explores alternatives, such as micromobility options, to effectively substitute short-distance trips, thereby fostering sustainable rural mobility practices that will help re-inhabit the region
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
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
