Calibrating Questionnaires with Weekly Diaries : An Application in Religious Behavior, Netherlands 1975 to 2005
Full text linkThis article presents an innovative approach to improve the power of questionnaires by combining them with weekly diaries. The aim is to show how one can calibrate information collected from questionnaires, which provide a distribution that is in general biased, with diary data, which are more accurate but cannot provide a distribution across a range of frequencies. These problems become even more pronounced when the object of analysis is a specific issue, such as religious practice, the focus of this study. The suggested user-friendly model uses the more accurate diary data to adjust the distribution produced by the standard questions and enables researchers to obviate the problems of the two data collection methods. To present a practical application, the Time Budget Survey, conducted at five-year intervals between 1975 and 2005 in the Netherlands, is used
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
Possiamo ancora dirci cristiani? La volatilità della partecipazione individuale alla messa
No full textCan We Still Call Ourselves Christian? The Inconsistency of Individual Church Attendance
In this paper we will analyse the data from surveys carried out in Italy between 1997 and 2005 as part of the Ilfi panel. We will focus in particular on statements about frequency of churchgoing given by panel members over the years and show that they are characterized by a significant degree of inconsistency. We will show that this interesting but unexpected result can also be found in many other international panels and therefore cannot be attributed to bias resulting from the methodology adopted in the panel. Furthermore, we will see that individual inconsistency is generally not associated with paths of progressive rapprochement to or estrangement from religion and/or its practices. Instead, it is a form of «discontinuity» in frequency of churchgoing in its own right. Our analysis will then lead us to conclude that inconsistency and discontinuity are not the result of inappropriate response behaviour by interviewees and that they run through the main social segments (gender, age, education and area of residence). This characteristic pattern of mass attendance, which concerns at least 50-60% of the population, does not appear to take shape as an intermediate form of religiosity between regular churchgoers and non-churchgoers. Instead, it seems to signal the existence of a different type of religiosity
Church Attendance, Problems of Measurement, and Interpreting Indicators: A Study of Religious Practice in the United States, 1975–2010
No full textChurch attendance is usually measured in surveys by asking a direct question about frequency of churchgoing
over a preset period of time, which is typically a year. Different studies have cast doubt over the validity of this
indicator as it tends to overestimate actual attendance to a significant degree. The aim of this article is to compare
data on church attendance provided by two different types of research conducted in the United States between
1975 and 2010: survey data (GSS) and data obtained from time use surveys (ATUS). This comparison has three
main objectives: (1) to confirm the hypothesis that survey data tend to overestimate actual attendance; (2) to show
that this overestimation is not constant over time and space, but tends to vary in an erratic and unpredictable
way; and (3) to demonstrate that data provided by time use surveys are more reliable than the frequencies of
churchgoing provided by traditional surveys when the objective is to identify trends in religiosity in a population
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
