Cagliari and smart urban mobility: Analysis and comparison
Full text linkIn recent years, city officials in Cagliari (Italy) have shown a particular interest in policies and strategies that promote sustainable urbanmobility. The UrbanMobility Plan (PianoUrbano dellaMobilità), drafted in 2009, provides an important tool, transforming Cagliari's mobility in a smart direction by promoting alternative means of transport to the private vehicle. This paper describes a quantitative methodology for evaluating urban mobility in Cagliari, using a synthetic indicator, and suggests steps that Cagliari could take to meet international best practices for transportation. The data needed to analyse Cagliari's urban mobility are gathered, and the findings are compared to those fromother comparable international cities. This intercity comparison allows the authors to consider how best to orient Cagliari's mobility towards international best practices

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
Techno-economic analysis of biogas production and use scenarios in a small island energy system
No full textThis paper investigates the economic, energy and environmental benefits given by the installation of an anaerobic digester in a small island. Particularly, the island of Procida is chosen as a case study where the production of organic fraction of municipal solid waste is equal to 2477 t/year. Three scenarios are hypothesized for the use of the locally produced biogas, namely: (i) upgrading of biogas and injection into the gas grid for the residential sector (replacing 21% of natural gas consumption); (ii) upgrading and use in transport sector (covering waste trucks, non-organic waste ferry and shuttle buses consumptions); (iii) use of biogas in a Combined Heat and Power (CHP) plant (covering 4% of electricity consumptions). The scenarios are analysed and compared in economic, emissions and energy terms. Although the biogas covers just a small part of consumption, it can still provide a relevant contribution to the island energy system by diversifying the energy mix while increasing the renewable energy sources penetration and also increasing the independence. The results show advantageous payback time (4–5 years), and this is mainly due to the significant savings in the maritime transport and the partial avoidance of the waste disposal on the mainland the incentives
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
Value creation in banking through strategic alliances and joint ventures
No full text"A large number of studies (DeYoung et al., 2009) analyze merger outcomes in the financial industry, while other forms of business cooperation are still poorly investigated. Our paper examines results of strategic alliances and joint ventures in European and US banking over the period 1999–2009. First, we estimate abnormal returns around the deal announcement date and then these are regressed on a large set of explanatory variables. We show that joint ventures create shareholder value when involving non-banking financial partners and allowing banks to expand abroad, while international strategic alliances tend to destroy shareholder value
