Peter Vink : 'combinatie diagnostiek en advies sterk punt PPO'
No full textNa veertig jaar neemt Peter Vink afscheid van het bloembollenonderzoek. Tussen 1972 en 2012 werkte hij in verschillende functies van het toenmalige LBO en nu PPO, waarvan het langst bij het diagnostisch onderzoek. Met zijn vertrek komt er voorlopig ook een einde aan de serie Ziek en zeer. Het diagnostisch werk blijft bij PPO
Peter Vink in gesprek met beroemde ergonomen: 10 vragen aan prof. Hans Dirken
No full textProf. Hans Dirken is een bekende naam voor ergonomen in Nederland. Onlangs heeft hij zijn afscheidsrede gehouden. Veel industrieel ontwerpers kennen hem van de colleges die hij heeft gegeven aan de TU Delft bij industrieel ontwerpen. Anderen kennem hem van het boek productergonomie nen weer anderen gebruiken zijn DINED-tabel voor antropometrie. In dit artikel een interview van TNO Arbeid-medewerker Peter Vink met Hans Dirken over ergonomie. www.humanfactors.n
12 vragen aan dr. ir. Johan Molenbroek: Peter Vink in gesprek met beroemde ergonomen
No full textDr. Ir. Johan Molenbroek is als ergonoom bekend vanwege de DINED tabel, die hij samen met prof. Dirken in 1986 maakte. In die tabel staan de antropometrische afmetingen van de Nederlandse bevolking. De tabel was eerst alleen bedoeld voor studenten Industrieel Ontwerpen (TU Delft) en werd later als norm gehanteerd voor heel Nederland en is ook interactief gemaakt. In dit artikel een interview van TNO Arbeid-medewerker Peter Vink met Johan Molenbroek over ergonomie. www.humanfactors.n

They will sit in tight and uncomfortable seating to save money, complain about it in surveys and then do it all over again.

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
