A Cross-Cultural Investigation of New Product Strategies for Technological and Design Innovations
No full textAlthough design and technological innovations are conceptually distinct and require significantly different resource investments by the firm, little is known about how differing strategies employed in relation to these new products influence changes in market share across national cultures. In this
study we provide insights on how technological and design product innovations and product portfolio breadth strategies influence changes in market share within 26 technological and 12 design innovations across 17 firms operating in eight European countries. The results indicate that the
positive effect of design innovation on changes in market share strengthen as individualism increases and indulgence increases whereas the positive relationship between technological innovations and market share are weakened as uncertainty avoidance and indulgence increases. We
also find that the positive relationship between design product portfolio breadth strategies and changes in market share is strengthened as individualism and indulgence increase, but weakened as uncertainty avoidance increases whereas the positive relationship between technological product portfolio breadth and changes in market share is strengthened as individualism increases
Specification Errors in Spatial Models: Impacts on Modeling and Estimation.
No full textA principal motivation for the research reported in this paper is to seek to understand what consequences can result from an erroneous specification of the lattice topology when an autoregressive spatial model is employed for inferential purposes. The first part of the discussion concerns impacts of such a specification error on the resulting dependence structure among data in SAR and CAR models. Although some ideas on this matter can be found in popular monographs about spatial statistics (Cliff and Ord 1981; Griffith 1988; Cressie 1993; Guyon 1995), the problem does not seem to have been attacked directly in the literature, two exceptions being Griffith (1995) and Griffith and Lagona (1997). In this paper an additional step is made in this direction, extensively using the theory of power series for matrices (see, for instance, Cooke 1950) and basic graph theory (see, for instance, Ore 1960). The second part of the discussion concerns impacts of a misspecified lattice topology on the quality of popular estimation procedures for SAR and CAR models. Because estimator quality can be measured by sampling distribution properties, unbiasedness and efficiency are considered here as basic measures of it. For this problem, a useful starting point is furnished by Oksanen (1991), and Cordey and Griffith's (1993) work is extended here. Much of the finite sample mathematical statistics summarized in this paper is numerically demonstrated in Griffith (1995). And, the Jacobian work outlined in Griffith and Sone (1995) is exploited to attain selected analytical results

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
