The electronic questionnaire in ISTAT’s new CAPI/CATI Labour Force Survey
No full textWith the aim of complying to EUROSTAT standards, two years ago ISTAT began to design a new labour force survey. After an experimental phase, the survey is now being run in
parallel with the current one and will substitute it completely during 2004. Innovations in the new survey concerned both contents and technical aspects. In particular, concerning the survey technique, we passed from a PAPI technique handled by interviewers of the municipalities which entered the sample, to a mixed technique: CAPI for the first family interviews and CATI for the confirmation interviews following the first.
The questionnaire for the new survey is particularly complex and consists in a general opening part which collects information on the family’s demographic characteristics
and 12 sections of which 10 are repeated for each family member. The use of an electronic questionnaire has allowed for automatic branching, the activation of online help upon request of the interviewer, the interactive coding of open items using a search engine for certain key variables (such as economic activity and profession), the introduction of soft and hard control mechanisms of range and coherence (with the
possibility of conciliating on the spot), managing confirmation items for waves following the first. All of this has helped simplify the interview and therefore significantly improve data quality. To evaluate such improvement, we have compared
the off-line check programme of the old survey with the on-line check programme of the new survey, analysing the number of partial non-responses, the number of edit
activations, the number of conciliations in the new survey and the number of soft controls purposefully not corrected (which shouldn’t therefore be imputed automatically). The significantly better results for the new survey have confirmed the correctness of the choice of an electronic questionnaire as data collection instrument.
Comparisons between the qualitative standards of the two surveys will be developed in order to analyse longitudinal aspects of the sample, examining in detail the effects of a
confirmation questionnaire in the waves following the first and the use of a CATI technique
Il conseguimento della qualità grazie alla progettazione ed al controllo del questionario elettronico
No full textL’impiego di un questionario elettronico e, soprattutto, di una rete di rilevatori professionali
dell’Istat permette un maggior controllo sul processo di produzione del dato migliorando
decisamente la qualità dell’informazione raccolta.
Considerato che una parte rilevante dell’errore non campionario si verifica durante la
rilevazione e la registrazione delle informazioni, il questionario elettronico gioca un ruolo di
primo piano nel prevenirlo e ridurlo. In questa ottica, l’indagine definitiva è stata preceduta da
indagini pilota che hanno permesso di testare diverse
versioni del questionario. La versione definitiva è nata dopo un attento studio della letteratura
dedicata all’argomento, dei regolamenti Eurostat e delle indagini svolte in altri paesi, nonché da
un intenso monitoraggio sul campo
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
