The opposite effects of semantic retrieval on prior and future learning
Get PDFRecently, interest in the effects of testing on memory has increased. In this set of experiments, I examined the effects of interleaved semantic retrieval on previous and future learning within a multi-list learning paradigm. Interleaved retrieval led to enhanced memory for lists learned following retrieval. In contrast, memory was impaired for lists learned prior to retrieval (Experiment 1). These results are consistent with recent work in multi-list learning and in the list-before-the-last paradigm, both of which reveal a crucial role for retrieval in enhancing list segregation. This pattern of results also follows clearly from a theoretical perspective in which retrieval drives internal contextual change, and contextual overlap between study and test promotes better memory. Consistent with that perspective, a 15-minute delay before the final test eliminated both effects (Experiment 2). Experiment 3 replicated the results of Experiment 1 with materials more appropriate for educational settings: interleaved semantic retrieval led learners to be more able to answer questions correctly about later texts but less likely to do so about earlier texts.Item withdrawn by Mark Zulauf ([email protected]) on 2012-07-16T19:16:59Z

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
The influence of intervening tasks on memory
Get PDFSubmission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-05-01The student, Kristin Divis, accepted the attached license on 2016-03-31 at 16:18."Learning new information is rarely done in isolation outside the laboratory. What one does between study sessions is important for later retrieval of the studied material. Previous research has shown that interleaved semantic retrieval leads to enhanced memory for later-learned items but to reduced memory for earlier-learned items (Divis & Benjamin, 2014). Retrieval-induced distinction provides one account for the opposite effects of retrieval on memory for early versus later material. By that view, retrieval serves to ""spread out"" the memory representations, making them (1) more distinct and less likely to interfere with each other and (2) rendering earlier events mentally more distant and harder to access at the time of test. Here, I expand on prior work examining the influence of intervening tasks on memory. Experiment 1 examines the effect of interleaved periods of task switching on memory for materials learned prior to or following the task switching intervention. Switching tasks (50% retrieval and 50% control) between periods of learning leads to similar benefits as those provided by a retrieval intervention. Experiments 2A and 2B examine the effects of intervening task on interlist intrusions. List distinction is enhanced when lists are separated by retrieval tasks, as seen by a reduction in interlist intrusions. Experiment 3 integrates and extends many of the components of prior studies by examining the influence of intervening retrieval on memory for complex, narrative text materials that share repeated, conflicting, and unique information. It highlights important boundaries to the influence of retrieval-induced distinction and provides a launching point for future studies examining the application of these intervening tasks in more ecologically relevant settings."The student, Kristin Divis, submitted this Dissertation for approval on 2016-03-31 at 16:24.This Dissertation was approved for publication on 2016-04-05 at 09:57.DSpace SAF Submission Ingestion Package generated from Vireo submission #9135 on 2016-07-07 at 14:16:24Made available in DSpace on 2016-07-07T21:14:32Z (GMT).

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
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
