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
The role of maternal postnatal depression in the construction of the attachment and triadic relationship.
No full textBackground: studies show how child development and the construction of primary affective-relational interaction could be compromised by post partum maternal depression . The aims are: a) to observe triadic interactions in families with or without maternal depressive symptoms. b) to study different styles of child’s attachment with mothers with or without post partum depression. Methods: the sample is composed by an experimental group, of 13 families, in which mothers show depressive symptoms in the post partum, and a control group without depressive symptoms .The study investigate: depressive symptoms in the post partum studied at first and at 9th month post partum ( Edinburgh Postnatal Depression Scale, Cox, Holden Sagovsky, 1987); triadic interactions during pregnancy and at 4th , 9th, 12th and 18th month of infant’s life ( Lausanne Triadic Play Fivaz-Depeuersinge, Corboz-Warnery, 2000), infant temperament at 4th and 9th month of infant’s life ( Infant Behavior Questionnaire, Rothbart, Garstein,2002) pattern of attachment at 12th month of infant’s life ( Strange Situation Procedure, Ainsworth, Blehar, Water, Wall, 1978) and the attachment reppresentation in mother and father during pregnancy ( Adult Attachment Interview, George, Kaplan, Main, 1984) Results: results show a) an improvement in triadic interaction during the time for all the mothers. b) no statistical differences between the two sample in the quality of the early triadic interactions. Data involving the construction of attachment are under study. Conclusions: postnatal depression doesn’t seems to influence triadic interaction, maybe for the role of father as protective and supportive factor for the family
A triadic and contextual perspective on parenting development from pregnancy to the child's preschool age.
Get PDFBackground: many studies have highlighted the central role of the quality of early interactions between the child and his/her caregivers and of the parenting style in putting the basis for child's socio-emotional development and adjustment. The framework provided by Fivaz-Depeursinge and Corboz-Warnery (1999)seems to give the chance for a new view on these issues by moving the focus of the research towards the triadic (mother-father-child) interactive system as the main object of investigation. In this perspective the aims of the study were to investigate the relationship between : a) individual characteristics of parents (affective-relational hystory,presence of postnatal depressive symptoms), b) contextual sources of stress and support (the quality of the marital relationship, the socio- economic status) and c) chatracteristics of the child (age, gender, adjustment) and the development of dyadic and triadic competences from pregnancy to the preschool age of the child.
Method: 35 non-referred primiparous families were recruited at chld-birth classes. All the families have been seen during pregnancy, at the 4th, 9th, 12th and at the 4th year of the child. Measures included : self report questionnaires (Dyadic Adjustment Scale, Questionnaire on Father Involvment, Edinburgh Postnatal Depression Scale), interviews ( Adult Attachment Interview, Symptom Checklist modified ), and observational procedures (Lausanne Trilogue Play).
Results: preliminary results show: a) substantial instability of the quality of the family triadic interactions from pregnancy to the child's preschool age; b) a significant increase both in the quality of triadic interactions and the degree of father longitudinal perspective. Conclusions: these observations seem to provide a first evidence of the close relationship between the two constructs (the quality of triadic interactions and the father involvment) during early childhood and their mutual interdependence in fostering a relational context functional to the well-being and the development of the child
Post-partum depression: effects on the construction of the bond of attachment and triadic relations.
No full textBackground Post partum maternal depression is the most studied issue as potential risk factor for child development and for the construction of primary affective-relational interactions. The aims of the work are: a) to study the quality of triadic (mother-father-child) interactions in families with mothers with and without post partum depression; b) the association between maternal psychological distress and different styles of attachment in the child. Method The study includes an experimental sample composed by 22 families, in which mothers show depressive symptoms of post-partum disorder (Edinburgh Postnatal Depression Scale, Cox, Holden, Sagovsky, 1987), and a control sample (21 families). The family were evaluated on specific areas: triadic interactions (Lausanne Trilogue Play, LTP Fivaz-Depeursinge, Corboz-Warnery 2000), infant temperament (Infant Behavior Questionnarie, Rothbart, Garstein 2002), pattern of attachment studied in the first year of infant’s life (Strange Situation Procedure, SSP, Ainsworth, Blehar, Water, Wall, 1978) and during pregnancy (Adult Attachment Interview, Geoge, Kaplan, Main, 1984). Results Results show a) any statistical differences between two sample on triadic interactions; b) an improvement in triadic interaction both in families with and without depressed mothers during the time. Also data on the part of research that involves the construction of the child’s attachment bond are under study. Conclusions These early results show no differences between the two samples on triadic interactions. We hypothesize that the presence of father could be a protective factor during the family interactions as main support figure for the family
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
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
