Urban Ecosystem Services to Support the Design Process in Urban Environment. A Case Study of the Municipality of Milan
No full textIn dense urban areas nature capital is a vital resource for providing numerous ecosystem services important for human welfare and survival but at the same time cities provide several different private and public services. Both, natural and human services, contribute to the overall well being of the citizens. The present paper aims at mapping and evaluating the “Urban ecosystem services” (UESs) that are generated from natural capital in combination with human-derived capital, and that contribute, directly or indirectly, to human well-being in urban areas. This paper aims at analysing, mapping and evaluating different types of UESs both natural and human origin in the case study of the municipality of Milan. A Multi-Criteria Decision Analysis (MCDA) approach has been implemented to synthetize and map the UESs. Finally, the paper describes how the present approach can support the design and urban planning process
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
International R&D partnerships: The role of government funding in reducing transaction costs and opportunistic behavior
No full textProtection Requirements in Distribution Systems with High Penetration of DG and Possibility of Intentional Islanding
No full textDistribution systems are generally radial in nature, characterized by a single source feeding a number of downstream networks whose protection scheme has been designed assuming in the system unidirectional power flows.
Difficulties to strengthen the transmission network by means of new overhead transmission lines because of their great unpopularity ('not in my back-yard' attitude), are leading to satisfy the ever increasing of load demand by connecting DG to distribution feeders rather than expanding transmission facilities. The presence of DG with the injection of active and reactive power alters the power flow distribution and, in turn, affects the network voltage profile. The impact of DG operation on protection performance might be critical because after connecting distributed generation, part of the system may no longer be radial, thus coordination might not longer hold. Since feeders consist, in some cases, of long overhead lines (e.g. in rural areas), they are characterized by high outage rates. In recent years, the islanding operation of portions of a distribution grid has become an important topic, widely discussed in the academic and industrial communities. In the event of failure of the main power supply, the islanded operation may improve the quality and continuity of the power supply. This operation mode is encouraged by the small sized electrical power generation technologies and mostly in order to assure power supply in case of black-out. If the DGs have sufficient capacity to sustain the loads connected to that portion of distribution system that houses the DG, a temporary autonomous island my be created. One of the goals of forming a “microgrid” is to provide a back-up to loads. In order to apply this concept, a number of problems must be solved. First of all the protection system must provide protective devices capable to work correctly both in the grid connection mode and in islanded mode. In this paper we explore the possibility of applying new protection schemes by pointing out traditional and innovative techniques in maintaining coordination and by developing methods to assure protection for an islanded portion of the system supplied by DGs
An inter- and transdisciplinary, multiscale and mixed methods pathway to study smart agriculture in Italy
No full textThis chapter aims to design such an inter- and transdisciplinary, multiscale and mixed method pathway to provide policy makers and stakeholders with a rationale framework of analysis for Smart Agriculture (SA) applied to the urban-rural relationships of several Italian case studies. The urban area of Pisa is situated near the coast in Tuscany and is made of a set of seven small towns. Agricultural areas in the metropolitan region are close to very urbanized and industrialized areas however, a deeply rooted rural tradition still resists. SA can be an experimental field where decision makers, civil society, academia and other actors cooperate within the proposed methodological framework to improve the urban-rural link in metropolitan regions. To date, multidisciplinary approaches on agri-urban region have mainly compared results from different disciplines regarding case study analyses. The promotion of peri-urban agriculture and rural-urban links is at the core of the pact
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
