Do they Play as Intended? - Comparing Aggregated and Temporal Behavioral Analysis in a Persuasive Gamified System
No full textGamified systems nurture an ulterior goal set by their designers (e.g., a positive behavioral change). Behavioral profiling allows understanding whether users play as intended and reach such a goal. Analyzing in-game behaviors can also highlight unexpected interaction patterns or unengaged users. Current logging systems can track and store any in-game action. However, such high-dimensional data should be carefully processed to retain relevant knowledge while filtering unnecessary noise. Analysts can either aggregate data into a single data point per player or maintain temporal information. This study compares aggregated and temporal behavioral analysis conducted on a gamified system, promoting sustainable mobility (Play&Go). Results show how, in Play&Go, aggregated analysis conveys information on long-term winning strategies, whereas temporal analysis describes short-term strategies. Additionally, studying the temporal evolution of players' behaviors emphasizes a sharp division among engaged and unengaged users. We show how aggregated and temporal analysis hold a complementary view of players' experiences
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
What is the Effectiveness of Electrical Stimulation to the Upper Extremity on ADL Performance for Adults After a Stroke?
No full textA stroke, also known as a cerebrovascular accident (CVA), occurs when blood flow inside of the brain is interrupted and results in cell death within the brain tissue. In the United States, more than 795,000 people experience a stroke yearly, 87% of which are ischemic and 13% hemorrhagic (Centers for Disease Control and Prevention [CDC], 2022). An ischemic stroke is caused by a blockage, usually a clot, that disrupts the flow of blood within the brain, and a hemorrhagic stroke is due to the rupture of a blood vessel within the brain that causes bleeding. (Unnithan et al., 2022). Stroke, either ischemic or hemorrhagic, is the leading cause of serious long-term disability in the United States as it can greatly reduce mobility and function, especially in people 65 years and older (CDC, 2022). A CVA can negatively affect a person’s independence and safety with activities of daily living (ADLs) including dressing, bathing, toileting, and self-feeding. The purpose of this analysis was to critically appraise different types and levels of interventions with electrical stimulation to the upper extremity to determine the effectiveness on ADL performance for adults after a stroke. Level IA and level IB articles were analyzed and included in this critically appraised topic (CAT) if they were completed in the last 3 years, included participants who have experienced a CVA, and utilized electrical stimulation for intervention. The analysis showed that using electrical simulation on the upper extremity is effective at improving ADL performance post stroke. All interventions require further research with larger sample sizes and specific protocols to determine the most effective way to prescribe electrical stimulation
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
