Data supporting Reactive anti-predator behavioral strategy shaped by predator characteristics
No full textSee readmeLarge mammalian herbivores use a diverse array of strategies to survive predator encounters including flight, grouping, vigilance, warning signals, and fitness indicators. While anti-predator strategies appear to be driven by specific predator traits, no prior studies have rigorously evaluated whether predator hunting characteristics predict reactive anti-predator responses. We experimentally investigated behavioral decisions made by free-ranging impala, wildebeest, and zebra during encounters with model predators with different functional traits. Here, we provide data from 365 trials between the focal herbivore species and models of African lion (Panthera leo), spotted hyena (Crocuta crocuta), cheetah (Acinonyx jubatus), African wild dog (Lycaon pictus), and two non-threatening controls (impala Aepyceros melampus and Thomson's gazelle Eudorcas thomsonii).National Science Foundation: GRFP #00039202, PRFB #1810586Palmer, Meredith S; Packer, Craig.

Snapshot Safari Educational Materials
No full textThese materials were created by Jessica Dewey as part of a Ph.D. program at University of Minnesota. This collection contains six educational activities to teach ecological principles via authentic learning experiences using read data from our wildlife surveys. Activity 1 guides students through setting up a Zooniverse account and take part in citizen science projects. Activity 2 helps students formulate ecological questions base on camera trap image data. Activity 3 teaches students about the different daily activity patterns of African species. Activity 4 presents students with data from a predator playback experiment and asks students to formulate hypotheses about predator-prey interactions. Activity 5 guides students through the process of connecting to the Zooniverse mobile app. Activity 6 presents an interactive timeline of conservation activities at the Snapshot Safari sites used in these programs. As a note: camera trap data is delivered to the UMN Lion Center several times a year. If a project you are interested in does not have data at the moment, check back soon! Classified images can still be accessed by clicking the "Classify" tab within individual projects.Snapshot Safari (www.snapshotsafari.org) is a cross-continental network of biodiversity monitoring programs run by the University of Minnesota Lion Center (www.lioncenter.umn.edu/snapshot-safari). To address the urgent need for accurately assessing vulnerable wildlife populations, we deployed over two dozen camera trap surveys distributed in protected areas across Africa. We rely on the help of online volunteers ("citizen scientists") to help classify animals captured in our millions of camera trap images. The citizen science platform provides a novel opportunity for public engagement and science education, and we have created educational multimedia based on the Snapshot Safari citizen science experience to promote these learning opportunities. Here, we present activities and videos aimed at a middle school-level audience that use our camera trap images to teach ecological and conservation principles.Palmer, Meredith S; Dewey, Jessica; Huebner, Sarah.

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
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
