Knowledge growth through inter-organizational knowledge recombination: an analysis of the US semiconductor industry between 1976-2002
No full textSi dà troppo spesso per scontato che le scelte e le soluzioni organizzative incidano profondamente sulle performance aziendali. Conseguentemente, i successi, le forze competitive emergenti, gli interventi efficaci sembrerebbero nascere e dipendere dalle capacità di innovare e di differenziare gli assetti organizzativi. I contributi raccolti in questo volume offrono una risposta meno scontata e più efficace, tracciando a partire dai diversi programmi e progetti di ricerca un percorso che tocca modalità, motivi, tempi e luoghi della differenza organizzativa. Diversi i temi che compongono questo mosaico di studi: il valore dell’organizzazione e le performance aziendali; le relazioni di lavoro e la gestione delle risorse umane; i modelli organizzativi dell’innovazione; le tecnologie di informazione e di comunicazione e gli assetti organizzativi; i fattori istituzionali, la cultura organizzativa e il management della diversità; le differenze organizzative nei settori economici, nelle relazioni interorganizzative e nel family business; le misure e la misurazione delle differenze negli studi organizzativi. Argomenti, tesi e conclusioni presentati e discussi sono un’occasione interessante di approfondimento sia per chi debba progettare, realizzare e gestire forme organizzative innovative, sia per chi voglia elaborare nuovi percorsi di ricerca e di studio
Where do firms' recombinant capabilities come from? Intraorganizational networks, knowledge, and firms' ability to innovate through technological recombination
No full textA firm's innovativeness is driven by its ability to recombine existing technologies. Elaborating on this argument, we contend that there exist two distinct types of recombinant capabilities. First, firms may innovate through recombinant creation, i.e., by creating technological combinations new to the firm. Second, they may innovate through recombinant reuse; i.e., by reconfiguring combinations already known to the firm. We study what drives each type of capability by examining two factors: the degree of integration of a firm's intraorganizational network and the diversity of its knowledge base. We test our theoretical predictions using data on 126 semiconductor firms between 1984 and 2003. Our analyses indicate that factors that favor recombinant creation generally hinder recombinant reuse and vice versa; however, combining an integrated collaboration network and a diverse knowledge base may concurrently enhance both recombinant capabilitie
Public knowledge, private gain: the effect of spillover networks on firms' innovative performance
No full textComplementing received research on the role of collaboration networks in fostering
interorganizational learning and innovation, the authors focus on the importance of learning from
other firms’ public knowledge. To this end they introduce the concept of spillover network—the
network of “source” firms whose public knowledge a “recipient” firm is able to readily absorb
and use as innovation input. Using patent-based data on a panel of semiconductor firms between
1976 and 2002, the authors demonstrate that firms’ innovative performance tends to be higher
when their spillover network is either munificent or rich in structural holes. However, being
exposed to a spillover network that is both munificent and rich in structural holes is generally
counterproductive. Consistent with the insight that the value of external knowledge inputs depends
on the firm-level resources with which it can be bundled, furthermore, the authors argue that the
extent to which firms benefit from their spillover network hinges on specific intraorganizational
factors—their scientific intensity and degree of downstream integration
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
