Knowledge building process in blended learning communities: forum usage evaluation from a participatory framework for distance cooperation.
No full textIn order to deeply understand knowledge building process in a Blended Learning Community (BLC)
and in attempt to define principles in Sociability Policy implementation (J. Preece, 2000), this paper
present a research experience moving from a Participatory Framework for Distance Cooperation
(Armenti, Cottone, Soru, 2008) developed within a Socio-Cultural Psychological approach (Vygotsky,
1978; Brown, Collins, & Duguid, 1989; Bruner, 1990; Cole, 1996; Mantovani, 1996).
Our Research experience is developed in a BLC, a kind of Web-Based Knowledge Community made
up by a traditional Face-to-Face (FTF) meetings and a Virtual Learning Environment (VLE) as
distance e-learning support tool. This kind of community is build for academic course, an increasing
experience in today academic learning.
Subject involved in the research are students attending Psychology course at a Bachelor Degree
Program, divided in 109 female and 22 male, with average age of 21.3, self selected in 12 workgroup,
with an average of 9 members per group. Core research procedure consist in build self selected
workgroup to accomplish a Collaborative Task via both FTF and CMC work condition. VLE is provided
with a Forum used both for group self-selection and workgroup management. From a major research
project (Armenti, Cottone, Soru, 2008), of which this study is part, we take the concept of participation,
and the definition of participation indexes in WKC. According to this findings we provide to study
participation in a BLC.
We conducted both quantitative and qualitative analysis. The former in order to provide for
participation indexes, the latter to understand different way of forum using in collaborative knowledge
task accomplishment. To this purpose we provide to a first categorization of forum posts in
"Knowledge Posts", "Organizational Posts" and "Social Posts": from all the contents available in VLE
we defined a set of words which can represent a common ground (Mantovani, 2001) in order to
identify the contents of the posts. Comparing this sets of words with the lexical occurrences in the
posts analysis we provide to identify and categorize posts.
Preliminary results show that the hypothesis by which students use the forum also for purpose
different from task accomplishment is confirmed. The categorization results useful and exhaustive
inclusive, even thought is just a preliminary attempt and needs better definition and expansion.
Practical application of the present research findings can be identified in defining guidelines to
improve either pro tem topics design and “on time intervention” in ongoing community participation, as
well as in participation evaluation.
An example of intervention can be showed moving from a Sociability Framework (J. Preece, 2001): if
we recognize a low social posting we can introduce a post in this category in order to encourage
students social-oriented interaction on this facet. The same strategies can be practiced for the other
categories providing a potential intervention at a community level
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
