Context effects in Web surveys
No full textThe quality of data collection on the Internet depends in part on potentially biasing
surface characteristics of Web pages, such as pop-up menus. Also, answering behavior
to survey questions is highly sensitive to cognitive contexts evoked by other
survey questions. A Web experiment with two experimental phases is used to identify
six potentially biasing factors. Manipulations of scale type, reading directionality,
cursor entry position, question order, and – in contrast to findings from offline research
– type of numerical labeling do not show effects. However, it is shown that it
makes a difference whether survey questions are presented together on one Web page
or separately on consecutive Web pages. Results are discussed with regard to general
as well as online specific implications for the design of survey instruments and multiple
response scales
Studying the Internet : a challenge for modern psychology
No full textIn the past 25 years, the Internet has developed from a modest military data network into a communication space frequented by more than 10 percent of the world's population, a majority of which are from industrialized countries such as the EU, Canada, Finland, Switzerland and the US (http://www.nua.ie). The psychological study of Internet usage has, over the same time span, evolved from being a study of fringe phenomena to being the study of an important and pervasive aspect of everyday life. There are several forms in which the Internet is relevant to psychology. The aim of the current special issue of the Swiss Journal of Psychology is to provide a forum for these new developments in psychological research. Indeed the research in this issue focuses on each of these three dimensions: a) studying the Internet as an object in itself, focusing in particular on its social-psychological implications, b) introducing new research methods and tools that enable us to do research in this environment, and c) using the Internet as a laboratory for gathering data about a wide range of topics which are usually studied only in the traditional psychology labs.publishe
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
