Tactical urban pocket parks (TUPPs) for subjective and objective multi-domain comfort enhancement
Full text linkCities face growing anthropogenic overheating phenomena, such as Urban Heat Island Effect and more intense and frequent heatwaves, impacting livability and wellbeing of local citizens and tourists. To mitigate such effects, passive mitigation strategies have been widely studied in the past decades, to be integrated within the built environment. The insertion of green areas, i.e. parks, in urban areas is among the most common passive strategies, however it presents numerous challenges, as traditional parks are difficult to insert in an existing packed urban texture. Hence, in this study, we examine the significance of strategic small urban parks related to various construction types. These parks can be seamlessly integrated through tactical urbanism interventions to enhance both the objective and subjective perception of overall comfort. By coupling human-centric microclimate monitoring campaigns in the small parks and surrounding blocks (objective analysis) with questionnaire surveys to parks' users (subjective multidomain analysis) we aim at assessing their effectiveness. Results show that Tactical Urban Pocket Parks (TUPP) can slightly improve objective whole comfort and significantly enhance the improvement of subjective comfort (from neutral/bad to good/very good)

On renewable energy community implementation in historic cities: A city-scale validated model
No full textRenewable Energy Communities (RECs) have emerged as a key strategy for transforming global energy management, promoting renewable energy generation and sharing, particularly through building-integrated photovoltaic (PV) systems. This innovative study focuses on designing a REC that facilitates renewable energy sharing between suburbs and historic city centers, where renewables installation is often constrained. Using city-scale energy simulations for the city of Perugia, Italy, the study evaluates electricity demand and potential PV production in two zones – northern and southern – each served by a unique primary energy station. Results revealed that multi-family houses in historic areas were the main contributors to overall electricity demand, while large offices had the highest average monthly consumption, particularly in summer. In the PV production analysis, increasing roof coverage to 70% significantly increased energy generation, with single-family houses in the northern zone producing up to 4 kWh more, daily, compared to 30% coverage. Mixed-use REC configurations (residential and commercial) achieved an optimal balance between self-sufficiency and energy exported to the grid, with average monthly shared energy reaching 32.4 kWh and 61.5 kWh in northern and southern areas, respectively. This study significantly contributes to demonstrating the feasibility of using suburbs-generated renewable energy to support energy innovation of historic city centers where restrictions on renewables installation are common. Findings underscore the potential for scalable, replicable REC models across other historic cities with similar constraints, but different climates and regulations. Such insights offer a pioneering model that bridges the gap between energy efficiency and heritage conservation in urban planning
The impact of energy transition policies on real estate efficiency and renewable energy communities (RECs): An analysis of public awareness and final energy uses in Italy
No full textThe Green Deal seeks to achieve carbon neutrality by 2050, positioning building operations and renewables promotion as a critical focus areas. Renewable Energy Communities (RECs) have emerged as a key driver of this transformation. In Italy, several policies have been introduced to promote their development; however, their impacts remain underexplored. This study examines the efficiency of real estate, the proliferation of RECs, and public perceptions related to these initiatives through a survey distributed at national level achieving 149 respondents. Findings reveal that 58 % of assessed buildings had undergone retrofit interventions, predominantly aimed at reducing energy bills. Furthermore, 46 % of respondents acknowledged the essential role of incentives in driving these changes, while 73 % of users reported modifications to their energy behaviours. Overall, occupants of retrofitted buildings and RECs participants demonstrated greater awareness of energy topics. These results underscore the critical importance of policy incentives in accelerating the energy transition and stress the need for targeted communication campaigns to enhance public awareness and engagement, so achieving the broader goal of carbon neutrality
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
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
