Raccogliere e valorizzare i dati sull’impatto. Quale contributo alla conoscenza?
Full text linkIl crescente interesse verso i temi della sostenibilità e dell’innovazione sociale apre nuove opportunità per declinare il grande potenziale dell’innovazione tecnologica a favore di obiettivi di impatto sociale ed ambien- tale. Allo stesso modo, tuttavia, la comunità scientifica che si occupa di questi temi si trova di fronte a nuove prove per rendere misurabili i risultati raggiunti: se da un lato tale sfida è ben avviata rispetto alla dimensione ambientale, grazie alla diffusione di standard ampiamente condivisi, dall’altro non si è raggiunto lo stesso livello di consapevolezza rispetto alla misurazione delle ricadute sociali.
Questa ricerca intende verificare la possibilità di superare il limite di misurabilità dell’impatto sociale integran- do innovazione sociale e innovazione digitale. Più nello specifico, raccogliendo i dati di misurazione di impatto sociale dalle fonti accreditate, si intende applicare metodi di big data analysis e business intelligence per costruire un set di informazioni utili per informare i processi di misurazione di impatto sociale e pervenire ad un data warehouse contenente benchmark su tutta la catena della teoria del cambiamento (input / attività / output/ outcome / social value / impact). I risultati mostrano un grande potenziale di informazioni generabili dalle tecnologie digitali per rendere più misurabili, affidabili e scalabili i processi di innovazione sociale
The Usefulness of Sharing Social Impact Data. Early Findings from an International Benchmarking on SROI Assessments
Full text linkThis paper aims at investigating a perspective for the social impact measurability by collecting and analysing open data at the international level. Our goal is to shed light on the unlocked potential of the knowledge produced by a global community of scholars and practitioners engaged in social impact measurement processes. Global open data on social impact assessment (SIA) have been mapped and collected in a database using the impact chain as a reference point for choosing the variables. In this paper, we focus on the potential use of these data to enable forecasting analysis about the expected social value and to inform decision-making processes aimed at responding to complex social challenges. The early findings suggest the opportunity of a wider action research initiative, by engaging different typologies of stakeholders and organizations aimed at incorporating social impact as a key strategic driver
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
District Heating Deployment and Energy-Saving Measures to Decarbonise the Building Stock in 100% Renewable Energy Systems
Full text linkAchieving a zero-emission building heating sector requires numerous strategies and detailed energy planning, in order to identify the optimal decarbonisation pathway. This work aims to assess the impact of district heating expansion and the implementation of energy-saving measures on the decarbonisation of the Italian building stock by 2050, analysing their combined impact, reciprocal effects, and technical-economic implications on the entire national energy system. The scenarios have been implemented and simulated with the H2RES software, a long-term energy planning optimisation model, built for the Italian national energy system. Results indicate that it is possible to decarbonise the heating system in an efficient and cost-effective manner by the year 2040. Heat pumps represent the optimal technology at both centralised and decentralised levels. District heating expansion is a priority for the decarbonisation of the building stock, allowing us to reduce costs, exploit thermal storage systems and provide system flexibility. In the best scenario, 40% of the Italian heat demand can be supplied by fourth-generation district heating. Energy-saving measures can reduce heat demand and primary energy but at higher annual costs and with a significant increase in investment. The combined simulation of the strategies within an optimisation model of the entire energy system enables the accurate assessment of the real impact of the various measures, considering their reciprocal effects and technical-economic implications
Pensare l'altro: l'attenzione e l'estraneità. Un'indagine fenomenologica di Bernhard Waldenfels
No full textDispelling 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
