Resilience and Gibrat’s law: Methodological considerations and empirical applications
No full textThis paper provides a new interpretation of resilience in the light of the Gibrat’s law. Resilience refers to the ability of a system to react to shocks, returning to the initial state. Gibrat’s law states that the growth of a particular entity is independent of its initial size. The occurrence of Gibrat’s law should therefore reduce the ability of an economic system to resist or to bounce back to the conditions that precede the shock. Our results show that – even if not perfectly – we can define a relationship between resilience and Gibrat’s law for the Italian regions
Resilience, Performance and Strategies in Firms’ Reactions to the Direct and Indirect Effects of a Natural Disaster
No full textThis work investigates the impacts of the 2012 Emilia-Romagna earthquake and looks at the capacity of the regional economic system to adapt to the shock generated by the seismic event. We contribute to the literature by distinguishing two different effects: direct (i.e. damages to production factors of the focal firm) and indirect effects (e.g. disruptions that affected industrial and business partners). The original dataset used and the chronological sequence of the information allow us to provide insightful evidence. The analysis of the two related effects generated by the same shock provides insights on the overall capacity of a regional system to adapt. Namely, the indirect damages appear as relevant as the direct damages, especially when looking at indicators of firm performance. In addition, indirect impacts are also relevant in shaping firm strategies and thus firm resilience
Larvae of Sulcascaris sulcata (Nematoda: Anisakidae), a parasite of sea turtles, infect the edible purple dye murex Bolinus brandaris in the Tyrrhenian Sea
No full textAnisakid nematodes are among the most common helminth parasites of the marine realm, particularly important for their implications with human infections and/or allergies. Members of the Anisakidae use aquatic mammals, birds and fish as definitive hosts, and crustaceans, fish and molluscs as intermediate/paratenic hosts. Sulcascaris sulcata, the only species in the monotypic genus Sulcascaris, represents the exception being a parasite of sea turtles as adult. The recent findings of larvae of S. sulcata in scallops (Pecten jacobeus and Aequipecten opercularis) and Mediterranean mussels Mytilus galloprovincialis intended for human consumption from the Mediterranean Sea caused concern regarding the sanitary control of edible molluscs and consumer safety. Herein, we investigated the larval anisakids collected from the purple dye murex, Bolinus brandaris, harvested for human consumption from the Central Mediterranean Sea (Tyrrhenian Sea). Morphological study and sequence analysis of the internal transcribed spacer regions of the ribosomal DNA and the mitochondrial cytochrome c oxidase subunit 2 gene locus revealed the occurrence of fourth stage larvae of S. sulcata in 16% of the purple dye murex examined. The present study adds the purple dye murex to the list of the known intermediate hosts of this parasite in the Mediterranean Sea and the northern coast of Campania region as site where individuals of loggerhead turtle and purple dye murex may become infected. This is the first study reporting an anisakid nematode in edible gastropods. Epidemiological features of infection in the purple dye murex and implications for gastropod safety and risk for consumers are discussed
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
Planning recommendations
No full textThe final outcome of the trAILs Research (The EU-project trAILs 2018-2021was co-financed by the European Regional Development (ERDF) within the Interreg Alpine Space Programme of the European Union), is a set of planning recommendations, expressed through the definition of principles to adhere to and performances to be achieved/guaranteed in the subsequent planning steps. Such a procedural-design methodology (from “project to process”) can be applied across the Alpine territory despite the locally different geographies, economies and societies. The results should recognize the plural condition of mountain identity, as well as the uncertainty of future developments. This condition requires new working approaches, not conventional projects. The purpose is to set up favourable conditions able to meet and integrate the necessary changes, considering the inevitably long-term perspective of spatial transformations
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
