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
Elena Franchi e Giorgia Proietti (éd.), Guerra e memoria nel mondo antico
Full text linkIl volume Guerra e memoria nel mondo antico, curato da Elena Franchi e Giorgia Proietti, raccoglie i contributi presentati dagli autori nel corso del seminario permanente organizzato dal LabSa (Laboratorio di Storia Antica del Dipartimento di Lettere e Filosofia dell’Università di Trento). Il libro analizza il rapporto tra guerra e memoria, affrontandolo da molteplici prospettive e in diversi contesti storico-sociali e geografici. L’introduzione di Marco Bettalli (p. 11-16) presenta la temati..
Città-porto, porti franchi e governo delle città
No full textinternazionali. Le città e le complessità dello spazio urbano variano e mutano in relazione a istanze interne e ad agenti esterni. Così avviene anche per le città-porto e per quella loro particolare declinazione che conosciamo sotto il nome di “porti franchi”. Nel caso delle città portuali la sfida appare ancora più affascinante se si considera che generalmente la loro storia non è mai lineare e lo è ancora meno se rapportata al fenomeno dei porti franchi che appaiono, già di primo
acchito, come una condizione di eccezionalità spesso temporanea in risposta a particolari criticità economiche, sociali e culturali: sovente le città portuali diventano porti franchi e poi tornano al rango di semplici città portuali, per tornare infine, ancora una volta, porti franchi quando il contesto economico, politico e internazionale lo richiede
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
AC series voltage regulator for Permanent Magnet Generators
No full textThis paper deals with an AC series voltage
regulator for permanent magnet generators. This project is
internationally registered with the publication number
WO/2009/004466 [1]. Mains examples of employment
includes: motorcycle generators, wind-turbines, agricultural
equipments, diesel generators. The comparison with the
state-of-the-art parallel architecture is discussed together
with energy efficiency simulations, specific advantages and
disadvantages for both the solutions. The operation
principles of the proposed regulation system is explained
with the help of block diagrams and circuits, and two
practical implementations are discussed: the first one
realized entirely with analog electronics, the second one with
a microcontroller. Finally some experimental
measurements are provided to validate the theory of
operation
Safety and sustainable development of European aquaculture: new tools for an environmentally sound aquaculture
No full textSustainable and long-term growth of the aquaculture industry should involve both ecologically sound practices and appropriate resource management. The increasing economic dimension of Mediterranean aquaculture is opening new economic niches and may be a valid support to reduce the pressure of traditional fisheries. Aquaculture practices can also lead to modifications of coastal habitats through the impact of wastes of land-based and open-sea mariculture facilities. In addition to these aspects which place a direct pressure on aquatic ecosystems and wild fishery resources, a wide range of environmental contaminants, such as chemicals used in farming operations, can accumulate in farmed organisms and put fish health and quality at risk. Thus, as aquaculture makes its transition to a major food-producing sector, proper assessment and control of environmental impacts and food safety awareness are becoming increasingly important. The development of simple tools able to monitor the extent of environmental and biological impacts associated with farming operations at various levels of biological complexity from the ecosystem to the organism level is required. Although a number of techniques for assessing the environmental and biological impact of pollutants in natural ecosystems are available, the development of practical and validated tools is sorely needed in aquaculture
