Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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
On the Causes and Consequences of Divorce
No full textIn most Western economies, the flourishing of the Welfare State has coincided with a decline of the role of the family: divorce has been introduced, and the number of marriages has decreased. We suggest that a taboo against divorce was part of the informal safety net in a period when social protection was provided by the family. Once the State started offering suitable alternatives, the taboo was no longer expedient, and was dropped. For the same reasons, marriage has become less popular. We further notice that divorce is an extremely costly process, and once allowed it may act as an independent reason for the reduction of the number of marriages. This latter result is especially evident under the assumption that agents subjectively evaluate the probability of facing a divorce using an availability heuristic.divorce, marriage, availability heuristic
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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

CO diffusing capacity in a general population sample: Relationships with cigarette smoking and airflow obstruction
No full textThe single-breath carbon monoxide diffusing capacity (DL(CO)(sb)) was measured together with ventilatory lung function tests as part of a survey of a general population sample living in Northern Italy (n = 2,481). Based on answers to an interviewer-administered questionnaire, subjects free of respiratory symptoms or diseases were identified. Data from subjects who had never regularly smoked cigarettes were used to derive reference equations for the test indexes, and data from the remaining subjects who had smoked were used to derive regression equations incorporating a term expressing cigarette consumption (cube root of pack-years) and a term indicating current smoking decrement, in order to obtain expected DL(CO)(sb) percent predicted. Neither number of cigarettes smoked daily or duration of smoking, in smokers, nor duration of smoking or years since quitting smoking, in ex-smokers, entered significantly the multiple-regression model. The mean values of DL(CO)(sb) were only slightly affected by the increasing degree of airway obstruction. When subjects with confirmed asthma were analyzed, after stratifying for different levels of FEV1/ FVC ratio, increased mean value of DL(CO)(sb) (over 100%) was found in those with an FEV1 FVC ratio between 75 and 65%. This cross-sectional analysis suggests that there is a decrease in DL(CO)(sb) with cumulative cigarette consumption even in healthy subjects. Further, it confirms the clinical observations of high DL(CO)(sb) values in asthmatic patients, at least in those with an initial degree of chronic airflow obstruction
