    Dependability of Two Group Observation Methods Across Rater and Time

    Collecting efficient and reliable behavior assessment data is often a goal for school districts and school psychologists. Unfortunately, the most accurate methods of behavior observations, systematic direct observations (SDO), can be time-intensive and often requires specific training. This often minimizes the number of trained professional available for observation procedures. Planned activity check (PAC), a variation of momentary time sampling, has the potential to combine the accuracy of SDO with efficiency. However, few studies have evaluated the psychometric principals of PAC. The current study sought to evaluate the reliability and dependability of PAC by comparing PAC to an individual-fixed (I-F) SDO. The current study assessed group-based behaviors using two methods of SDO: individual-fixed and PAC. Observations occurred across 6 classrooms for 10 consecutive days with classroom teachers implementing PAC in conjunction with trained researchers. Results from the current study yield positive outcomes of I-F and PAC being reliable and dependable measures of group-based behaviors with an I-F G-Coefficient of .959 and PAC G-Coefficient of .889. Results also indicated that SDO and PAC can be dependable measures in addition to being efficient with follow-up dependability studies indicating SDO after two days reaches a G coefficient of .826 and PAC after four days reaches a G coefficient of .814. Finally, social validity data taken by teachers at the completion of the study indicated favorable reviews of PAC across acceptability, understanding and feasibility

    The Classroom Password: An Independent Group Contingency Targeting Academic Engagement and Disruptive Behaviors In High School Classrooms

    The classroom password, an independent class-wide group contingency, was implemented in a high school setting in effort to determine its effects on academically engaged behaviors, disruptive behaviors and passively off-task behaviors. This was done using a reversal design across three classes. The focal point of this study was to determine if the classroom password would increase academic engagement. The classroom password was implemented by having the teacher select a word of the day that was then incorporated into the classes lecture. The students were given the word for the day before the lectures began and were required to code each time the word was spoken. Correct identification of the number of times the word was said entered the students into a drawing for a reward pool. Results yielded increases in academic engagement across classes and decreases in disruptive behaviors. No significant results were found for the reduction of passive off-task behaviors. Social validity data was taken across teachers and students, and suggested they found this intervention effective and socially valid. Results from this study suggest that this intervention is a valid option for implementation in a high school setting when increasing academic engagement is the target

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 PDF
    We 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 PDF
    We 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 text
    We 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
