Mathematics Anxiety and Mathematics Self-Efficacy as Predictors of Mathematics Teaching Self-Efficacy
Full text linkThe purpose of this multiple methods study was to investigate whether elementary mathematics teachers’ mathematics anxiety and/or mathematical efficacy predict their mathematical teaching efficacy. The study included 51 practicing elementary mathematics teachers in first through sixth grade. The teachers completed the Revised Mathematics Anxiety Rating Scale, the Mathematics Self-Efficacy Scale, and the Mathematics Teaching Efficacy Beliefs Instrument. From the survey results, four teachers, two that scored low anxiety and two that scored high efficacy, were selected to participate in classroom observations and semi structured interviews. Quantitative data were analyzed using hierarchical regression. The results were paradoxical. The R2 change indicated that mathematics anxiety and mathematics self-efficacy were both good predictors of mathematical teaching self-efficacy. However, the standardized coefficients were not statistically significant. The findings of the qualitative data suggest that elementary mathematics teachers with low anxiety and high mathematics self-efficacy do not consistently use best practices in mathematics instruction and prefer to use more traditional strategies during mathematics instruction
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

Prevailing over prejudice : a story of race, inequity, and education in Gonzales, Texas
Full text linktextThis dissertation traces the history of Edwards High School in Gonzales, Texas, from its origins in the late 1800s through its closure in 1965 and situates Edwards within the larger framework of secondary schooling for African-Americans in Texas. Although more than two hundred high schools for African-Americans existed in Texas for some period by 1947, little is known about these institutions, especially those located in small towns. Schooling for African-Americans following the Civil War was irregular and normally consisted only of elementary grades. As more schools became available, black students received an inequitable share of resources for their education and they did not share in the groundswell of high schools available to white students. Many of the high schools that became available to African-Americans during the first part of the twentieth century were located in urban areas. Little is known of the secondary institutions for African-Americans in the small towns of Texas. This study serves to recount the story of one such school. The study pays particular attention to the students, teachers, and curriculum of Edwards High School, focusing on the years between 1935 and 1965, the year the school closed due to desegregation. Archival materials provided information on student demographics, enrollment and attendance patterns, as well as student participation in activities. Oral history interviews offered a glimpse into the lived experience of those who attended Edwards High. Teachers’ certification records and salary data informed an understanding of Edwards High School’s faculty. The study sheds light on the relationship between teachers and students and between faculty and the larger African-American community in Gonzales. The curriculum of Edwards High changed over time. Changing state classification and accreditation standards provided the impetus for these changes. This examination of Edwards High School informs a greater understanding of secondary education for African-Americans in Texas.Curriculum and Instructio
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
