Role of Industrial District Externalities in Export and Value-added Performance: Evidence from the Population of Italian Firms
No full textBecchetti L., De Panizza A. and Oropallo F. (2007) Role of industrial district externalities in export and value-added performance: evidence from the population of Italian firms, Regional Studies 41, 601-621. The paper tries to shed light on the export and value-added performance of industrial districts by integrating information on the population of Italian firms (from the ASIA database of the Italian Statistical Institute) with balance sheet data for all limited-liability companies in selected manufacturing industries. The findings show that firms located in industrial districts (specialized or not in the leading manufacturing activity of the district) export more and have higher added value than firms located elsewhere, net of the impact of relevant controls. The robustness check undertaken on the agglomeration-performance nexus detects, as expected, a significant relationship between dichotomous district indicators and (global and industry-specific) continuous measures of agglomeration and specialization. Export and value-added performance results are confirmed when proxying location in industrial districts with these continuous variables and when considering the weight of subcontracting and outsourcing activities of productive units as additional controls. Becchetti L., De Panizza A. et Oropallo F. (2007) Le role des effets externes industriels dans les performances des exportations et de la valeur ajoutee: des preuves aupres des entreprises italiennes, Regional Studies 41, 601-621. Cet article cherche a eclaircir les performances des exportations et de la valeur ajoutee des districts industriels en integrant des donnees aupres du parc d'entreprises italiennes (la base de donnees ASIA de l'Institut italien de la statistique) a un bilan pour toute societe a responsabilite limitee dans certains secteurs industriels. Il s'avere que les entreprises situees dans des districts industriels (qu'elles se specialisent dans l'activite phare industrielle du district ou non) exportent plus et jouissent d'une valeur ajoutee plus elevee que ne le font les entreprises situees ailleurs, compte tenu de l'impact des controles en cours. Le controle de solidite fait sur la connexion agglomeration-performances laisse voir, comme prevu, un important rapport entre des indicateurs dichotomiques des districts et des mesures d'agglomeration et de specialisation continues (a la fois globales et specifiques). Si l'on assume des emplacements dans des districts industriels a partir de ces variables continues, et que l'on considere le poids de la sous-traitance et des approvisionnements externes des etablissements productifs comme des controles supplementaires, les performances des exportations et de la valeur ajoutee sont confirmees.

(2007) Die Rolle der Externalitaten von industriellen Bezirken fur die Export- und Wertsteigerungsleistung: Belege aus der Bevolkerung italienischer Firmen, Regional Studies 41, 601-621. In diesem Beitrag untersuchen wir die Exporte und die Wertsteigerungsleistung industrieller Bezirke, indem wir Informationen uber die Bevolkerung von italienischen Firmen (aus der ASIA-Datenbank des Statistikinstituts Italiens) mit den Bilanzdaten aller Gesellschaften mit beschrankter Haftung in ausgewahlten produzierenden Branchen kombinieren. Unsere Ergebnisse zeigen, dass Firmen in industriellen Bezirken (unabhangig davon, ob sie auf die fuhrende produzierende Aktivitat in diesem Bezirk spezialisiert sind) mehr exportieren und eine hohere Wertsteigerung erfahren als Firmen an anderen Standorten, auch wenn die Auswirkung der relevanten Kontrollen berucksichtigt wird. Die Robustheitsprufung der Ballungs-Leistungs-Verknupfung zeigt wie erwartet eine signifikante Beziehung zwischen den dichotomen Bezirksindikatoren und den (globalen und branchenspezifischen) kontinuierlichen Massstaben der Ballung und Spezialisierung. Die Ergebnisse hinsichtlich des Exports und der Wertsteigerungsleistung werden bestatigt, wenn man den Standort in industriellen Bezirken durch diese kontinuierlichen Variablen ersetzt und das Gewicht der Zulieferung und externen Vergabe von produktiven Einheiten als zusatzliche Kontrolle berucksichtigt.

(2007) El papel de los efectos externos en comarcas industriales para el rendimiento de exportacion y de valor anadido: ejemplo de la poblacion en empresas italianas, Regional Studies 41, 601-621. Con este ensayo pretendemos arrojar luz sobre el rendimiento de exportacion y valor anadido de las comarcas industriales al combinar informacion sobre la poblacion de las empresas italianas (base de datos ASIA del Instituto Italiano de Estadisticas) con datos de balances financieros para todas las sociedades de responsabilidad limitada en selectas industrias manufactureras. Nuestros resultados indican que las empresas ubicadas en comarcas industriales (especializadas o no en actividades lideres de fabricacion en la comarca) exportan mas y tienen un valor anadido superior que las empresas ubicadas en otros lugares, aunque se tenga en cuenta el impacto de los controles pertinentes. Al comprobar la solidez de los nexos entre aglomeracion y rendimiento, se detecta, tal como se preveia, una relacion significativa entre los indicadores dicotomicos de comarcas y las medidas continuas (para una industria o para todas) de aglomeracion y especializacion. Se confirman los resultados del rendimiento de la exportacion y del valor anadido al sustituir la ubicacion en las comarcas industriales por estas variables continuas y al considerar el peso de los subcontratos y servicios externos de gestion de las unidades productivas como controles adicionales.

Trade shocks, product mix adjustment and productivity growth in Italian manufacturing
No full textIn this paper, we use firm-level data on the universe of Italian manufacturing multi-product exporters to test whether demand shocks in export markets lead multi-product exporters to increase their productivity. The main mechanism behind the documented productivity gains is the reallocation of resources across products within firms (American Economic Review, 104, 2014 and 495; National Bureau of Economic Research Working Paper Series No. 22433, 2016). Intuitively, the increased demand stemming from foreign markets will induce firms to adjust their product mix by moving inputs from low to high productive/profitable uses. We find that these productivity gains are significant and can explain between 1/10 and 1/2 of aggregate productivity growth in the manufacturing sector
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
Dispelling 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
