No full textA New Method for Evaluating Knowledge, Beliefs, and Neuromyths About the Mind and Brain Among Italian Teachers
No full textTeachers often face situations that require them to apply knowledge about the mind and brain to education. Past studies have indicated that even if teachers show interest in cognitive neuroscience, they show high rates of adhesion to neuromyths. In the most commonly used questionnaire, however, respondents do not compare neuromyths and correct information based on neuroscience. The present study proposes a multiple-choice questionnaire that presents scenarios occurring in school. The most commonly used and the new questionnaire were administered to 174 Italian teachers. In the most commonly used questionnaire, teachers generally had the same likelihood of accepting neuromyths as the literature reports. In the new questionnaire, the levels of both general knowledge and beliefs about neuromyths were significantly lower. Moreover, it suggests that teachers' adhesion to neuromyths in realistic situations does not match their explicit beliefs. Thus, the present research proposes that the use of questions based on feasible scenarios is a useful method to assess neuromyths
MODULATION OF A FRONTO-PARIETAL NETWORK IN EVENT-BASED PROSPECTIVE MEMORY: AN rTMS STUDY.
No full textEvent-based prospective memory (PM) is a multi-component process that requires remembering the
delayed execution of an intended action in response to a pre-specified PM cue, while being actively
engaged in an ongoing task. Some neuroimaging studies have suggested that both prefrontal and parietal
areas are involved in the maintenance and realization of delayed intentions. In the present study,
transcranial magnetic stimulation (TMS) was used to investigate the causal involvement of frontal and
parietal areas in different stages of the PM process (in particular, target checking and intention retrieval),
and to determine the specific contribution of these regions to PM performance.
Our results demonstrate that repetitive TMS (rTMS) interferes with prospective memory performance
when applied at 150–350 ms to the right dorsolateral prefrontal cortex (DLPFC), and at 400–600 ms when
applied to the left posterior parietal cortex (PPC).
The present study provides clear evidence that the right DLPFC plays a crucial role in early components
of the PM process (target checking), while the left PPC seems to be mainly involved in later processes,
such as the retrieval of the intended action
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
