Beyond Manpower Planning: ROA's Labour Market Model and its Forecasts to 2002
Get PDFThis paper describes the forecasting model of the Research Centre for Education and the Labour Market (ROA), which has been developed for making forecasts about developments of the labour market position of different types of education with respect to the Dutch labour market. Every two years, ROA compiles forecasts of changes in the labour market in the medium term, differentiated by a large number of economic sectors, occupational classes and types of education to illustrate the meaning of the information. The paper aims particularly to describe the objectives, the basic principles, the theoretical foundations and the structure of ROA''s forecasting approach and the major labour market indicators in more detail. The forecast labour market developments for the types of education up to the year 2002 will also be presented. Due to the low level of aggregation used, these forecasts provide very useful information for people who are involved in decisions about educational investments.education, training and the labour market;
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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

Upgrading in the European Union
Get PDFHuman capital factor endowments have become one of the main determinants of international competitiveness. Both to catch up in the technological race and to increase the long-term flexibility of the workforce, industrialized countries require a highly skilled labour force. This paper analyzes the skills upgrading process in the European Union, as reflected in shifts in the occupational structure of employment and changes in the skill requirements in the various occupational fields. We distinguish between upgrading by recruitment policies and by training policies. Labour Force Survey data shows an increase in skill levels and rather stable participation in continuing vocational education. The data also reveal diverging trends, in the period 1983- 1991, between the various Member States of the European Union, both with regard to the skill level of the working population and the rate of participation in training activities. Estimation results show that, in general, intermediate skilled workers participate more in training activities than highly skilled workers. This suggests some substitutability between initial education (i.e. recruitment policies) and continuing training. However, if we correct for the occupational field in which workers are employed, recruitment policies and training policies appear to be complementary rather than substitutes. This means that within the various occupational fields, continuing training increases the skill gap between highly skilled and intermediately skilled workers. Moreover, both intermediate and highly skilled workers participate significantly more in continuing training than low skilled workers. This again indicates an increase in the skill gap in the labour force in the EU Member States, which means that continuing training fails to achieve the upgrading of low skilled workers which is required if the labour supply is to be adjusted to transfer human resources towards activities which match the EU''s comparative advantages.education, training and the labour market;
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
