Labour Productivity and Foreign Direct Investment in Irish Manufacturing Industry: A Decomposition Analysis
Overall labour productivity in the Irish manufacturing sector increased by 158 per cent between 1991 and 1999. This growth in labour productivity coincided with strong growth in employment during the same period, in stark contrast to the experience of other European countries. This paper examines the components of this labour productivity growth in the period 1991-1999, using a decomposition analysis based on plant level data. In order to account for the large presence of foreign plants we carry out our analysis separately for foreign and domestic plants, as well as for four ownership subgroups, four sectoral subgroups, and two time sub-periods. Our results show that although the main drivers of average labour productivity growth in all groups arise within plant and from plant entry, there are marked differences in the relative sizes of these effects across the ownership/sector/time-period.

We use a new sample of UK female identical twins to estimate economic returns to education. We use identical twins to control for family effects and ability bias (due to genes) and the education reported by the other twin to control for schooling measurement error. We also investigate the within-twin pair and within family correlations with observable correlates of ability. Our estimates suggest a return to schooling for females of about 7.7%. *Contact address: Jonathan Haskel, Economics, QMW, Mile End Rd, London E1 4NS, England; [email protected], <www.qmw.ac.uk/~ugte153>. We thank the DfEE and the ESRC for financial support. We are of course solely responsible for the views, opinions and errors in this paper. A particularly robust correlation in economics is that more educated people have higher earnings. Does this mean that a randomly selected person who invests in more education will earn higher wages? If the earnings/schooling relation is causal the answer is yes: education raises productivity and higher productivity raises wages. If the relation is spurious then no
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
