Teacher motivation and student learning
No full textTeachers’ motivation is likely to be a relevant factor affecting students’ learning.
We exploit the fact that motivated teachers are typically those who have chosen to be in a
given school, while teachers just waiting to move to another school may be rather demoti-
vated. We link this dimension of teacher motivation – as measured by the share of teachers
who asked to leave their current school – to students’ learning – as measured by their scores
in reading and math standardized tests in a national examination. We find that the share of
teachers applying for a transfer to another school negatively affects students’ achievements

No full textThe determinants of teacher mobility: Evidence using Italian teachers' transfer applications
No full textOf particular importance for education policy-makers is the possibility that teacher mobility adversely affects the quality of teaching in schools serving mainly disadvantaged and minority children. This paper examines the main drivers of the mobility of Italian teachers by using applications-to-transfer data. We find that teachers systematically try to move away from schools where teaching is likely to be more difficult because of the student mix or the social context of the school. Given the absence of any criteria other than seniority in regulating teachers' allocation across schools, disadvantaged students frequently end up with less experienced teachers who are often just waiting to move elsewhere

No full textHeterogeneity in health responses and anchoring vignettes
No full textIn this article we employ the tool of anchoring vignettes to analyze gender differences in self-assessments of health in Europe. We propose and estimate an extension of the basic vignette model for correcting the lack of interpersonal comparability of self-assessments on a categorical scale. Our extension allows for potential correlation in the self-assessments of health on different domains by including an unobservable individual effect, common to all domains but different across individuals, in both the thresholds and the equations for the latent health problems. After applying this model to the SHARE data, we find that vignettes help narrow gender differences in self-assessments of health, although these differences are not entirely eliminated
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
