Comprensibilità e gradevolezza nelle risposte a scale a 100 e a scale Likert
No full textIn this study different methods of scaling are compared, for what concern the agreeableness and
easiness in their compilation. Subject’s evaluation of a scaling instrument can considerably affect his
answers, influencing aspects as concentration, interest and engagement. Reliability of results is influenced
by the variability of these factors. From this point of view, the Likert scale method and the One
hundred scale methods (One hundred sum and One hundred point scales) were compared. The
evaluation of these instruments is generally positive. The Likert scale is preferred to the One hundred
scale, to the One hundred sum scale in particular, only if the former is made up by a few items.
When the Likert scale is presented in its traditional form, that is with a greater number of items, the
One hundred sum scale is preferred. Finally, no differences are revealed between the two One hundred
scales. It is important to notice that these judgements are seldom affected by subjects’ educational
level. Therefore, the One hundred scales can be used also when the analysed sample is
etherogeneous for what concerns socio-cultural dimensions
Confronto tra "scale a somma 100" e scale di Likert: elementi per la costruzione delle "scale a 100 punti". Una valutazione del servizio bancario
No full textIn this article the method of the “one hundred sum” scales is compared to the Likert type scales.
This comparison is made in the field of bank marketing. Given that the economic world is characterized
by situations of constant variability and turbulence, the quality of customer services assumes
great importance and much research has been carried out. This study, aiming to find out how quality
services are evaluated using a sample of 530 subjects, can be included in this field.
The study is carried out in three phases, in which an adapted Likert scale is used, and two types of
the one hundred scale are proposed. One is the classic type in which subjects have 100 points to be
distributed among the items; the other one is modified, with subjects having 100 points available for
each single item. Significant correlations are revealed with the Likert method for each type of scale,
and above all when using the “one hundred points” scale. In the latter the items are less interconnected
and, consequently, the modalitiy of reply is more similar to the Likert scale one. The one hundred
scales are, therefore, proposed as a quick and easy to use instrument, and also as a substitute for
scaling methods which are heavier and more complex for the administration, reply and statistical
analysis points of view
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
