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
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

Reexamining professional development through successful principals' perceptions
Get PDFtextPrincipal professional development is vital to the field of education because the principal is expected to be the instructional leader of a school. Even though principals do not provide instruction directly to students, their instructional leadership practices can greatly affect teacher practice and student learning. This descriptive case study examined the variety of professional development models created in Texas ISD (a pseudonym) to determine if one model is more effective than another in enhancing job performance. This study highlighted the principals' perceptions of a variety of components within professional development such as the delivery, design, how the learning needs are met, and how they helped enhance principal job performance. This qualitative case study design was seated within the constructs of Donald L. Kirkpatrick's (2006) Four-Levels of Learning and Evaluation Model that was utilized as the analytical tool to frame the initial and heuristic questions for the principal questionnaire and interviews. This Model guided the data collection, categorization, and emergent themes. Specifically, this study investigated the following: (a) aspects of principal professional development that enhance job performance as an instructional leader, (b) types of delivery and the impact it has on instructional leadership, and (c) comparisons of delivery models to identify the most effective. Ultimately, the findings of this study seek to provide supporting information to researchers and district leaders as they plan, design, and implement future effective principal professional development. The study focused on a group of nine successful principals in a Texas urban school system identified as Texas ISD. Examining the delivery models added to the body of literature regarding how to create effective principal professional development that helps principals enhance jobs performance and offer districts an alternative to the costly price of professional development. In Texas ISD, principal professional development was used as the vehicle for scale and sustainability of districtwide educational reform. In addition, the professional development assisted with K-12th grade vertical articulation of the school system's curriculum and educational plan. To analyze the impact of professional development on instructional leadership practices, questionnaires were given and interviews conducted in which individual perceptions of successful principals in Texas ISD were conducted.Educational Administratio
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

Troubling social justice in a single-sex public school : an ethnography of an emerging school culture
Get PDFtextThis ethno-historical undertaking captures the story of the implementation of one major US city's first and only single-sex public school and the consequent shaping of the school culture according to its unique context. A comprehensive literature review demonstrates race, socioeconomic status, gender, sexuality, and other contextual factors are important considerations when probing educational access and achievement and the development of school cultures. Moreover, principals -- their individual attributes and the cultures they create -- are key to understanding and interrogating equitable practices in schools. Findings substantiate the complex interface between historical, political, and socio-cultural contexts, stakeholder decision making in the ethnographic present, and the enactment and negotiation school culture vis-à-vis the intersectionalities of student identities. Findings suggest the conditions that facilitated the high achievement of the students in this study might be transferred under the right conditions including: a balance of strong leadership and principal and teacher autonomy; the enduring belief that any student can and will learn; a rigorous, non-segregated, college prep program, and; an informal curriculum that prepares students for academic and professional cultures. Findings also bring to the fore important considerations that must be addressed by practitioners and policymakers alike; specifically, students' difficulties concerning the "burden of acting white" and the "burden of acting straight." Finally, findings from this study suggest single-sex public options can be done legitimately and effectively but additional safeguards must be implemented by the US Department of Education to ensure both male and female students' civil rights are protected. Additionally, while some magnet schools such as the one studied are local sites of resistance that play a liberatory role for those distinctively involved, one cannot surmise that such local efforts -- which may be viewed by some as a site of relative privilege -- can alone overcome the serious striations that exist in the greater society.Educational Administratio

Assessing the impact of cultural proficiency training for central office administrators
Get PDFtextThe purpose of this study was to explore participants’ perceptions of the impact of a cultural proficiency workshop that discussed concepts of race and racism. Moreover, I was interested in understanding the factors and experiences associated with a greater likelihood that people would want to engage in dialogue on race and racism. The literature suggests that when discussions like these are broached, people can often become disinterested and disengaged (Derman-Sparks & Phillips, 1997; Diem & Carpenter, 2012; Singleton & Linton, 2006; Tatum, 1997). Therefore, if it is indeed pertinent for educators to be presented with knowledge that can be critical to student success, it is vital to understand what aspects of the training and what qualities of the participants lend themselves to a higher level of engagement and interest. To research these phenomena, a mixed method study design was employed. School district central office personnel were required to attend a culture proficiency professional development session which covered concepts of race and racism. I surveyed these participants to gather their perceptions about the impact of the training. In addition, several participants were interviewed. To answer the second research question, certain participants were asked to participate in a follow-up interview to determine the qualities and characteristics that created a greater likelihood that these individuals would see the importance of race-based discourse and continue these conversations. Findings suggest that workshop participants perceived that the workshop helped to increase their level of racial awareness and change their behaviors or disposition. However, it was found that additional follow-up was needed to sustain these efforts. They also expressed that these kinds of workshops are essential. For those who were likely to engage in race-based discourse, it was found that these individuals were racially aware, rejected notions of colorblindness, discovered race at a young age, were more likely to attend diverse schools and live in diverse neighborhoods and were likely to have faced discrimination as a person from an oppressed group or due to a close relationship with someone who was.Educational Administratio
