Carpal Tunnel syndrome symptoms in Esports players
Full text linkAbstract
The thesis study was conducted to identify the risk factors for Esports players when it comes to developing Carpal Tunnel syndrome, how prevalent the symptoms are, and what preventative measures can be taken based on current research and available treatment methods.
Methods
An overview was provided on the Esports industry and differences between playing computer games vs. traditional office work, and a literature review was conducted on Carpal tunnel syndrome definition, testing, risk factors and treatment. For the practical implementation, measurements were recorded in collaboration with 6 players from Tikka eSports and 2 independent players. For 7 days, the players filled a symptom and performance diary with attached software recording of mouse movement.
Results
Within the sample group was found that longer play time is not a risk factor for some of the Carpal tunnel syndrome symptoms. However, symptoms of burning in the mouse hand wrist increased proportionally to mouse distance travelled, and in addition there was found a decrease in self-reported performance. All in combination show that there may be a higher risk for players who need to use lower mouse sensitivity and therefore have increased travel area.
Conclusion
What the gathered data has shown is an example of physical wrist stress and potential Carpal Tunnel syndrome risk factors an Esports player could have. For any of the conclusions to be industry-relevant, a much larger size of players and longer-term measurements are needed. This study is the first of its kind and while the sample group is small, it opens the conversation about importance of conducting research and implementing preventative practices within the Esports industry
Fast Analysis of Total Polyphenol Content and Antioxidant Activity in Wines and Oenological Tannins Using a Flow Injection System with Tandem Diode Array and Electrochemical Detections
Full text linkAn analytical method for simultaneous determination of total polyphenol content (TPC) and antioxidant activity (AA) of wines (white and red wines) and oenological tannins, using a flow injection system with sequential diode array and electrochemical amperometry detectors (DAD-ECD), was proposed. The signal at 280 nm provided aggregate data for TPC. The anodic peak related to wine phenolic oxidation was scanned using pulsed integrated amperometry over the potential of 800 mV vs. Ag/AgCl, to obtain AA. Serial dilutions avoided the poisoning at the glassy carbon (GC) electrode and the linear response obtained with both detectors was compared with spectrophotometric assays commonly used in oenology laboratory. Intraday and interday analytical repetitions showed a good repeatability and reproducibility (relative standard deviation RSD < 6% for both detectors), and the satisfactory relationship between the proposed coupled flow injection/DAD-ECD and the classic UV methods (R2TPC = 0.9967; R2DPPH = 0.9621) confirmed the efficacy of flow injection analysis with a coupled detection system, for the reliable quality control of wine and wine-related products
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
Influence of yeast strains on phenolic composition and antioxidant activity of Vranec wines
No full textThe phenolic composition of ten autochthonous monovarietal Vranec red wines produced with different yeast strains was determined by HPLC-DAD analysis. Vranec wines were fermented with the following Saccharomyces cerevisiae yeast strains: Clos, RC212, D254, BDX (from Lallemand), and six Vinalco yeasts isolated from the Tikveš wine region (Republic of Macedonia). A total of 19 phenolic compounds were identified and quantified in wines and among them the malvidin-3-glucoside and its derivatives were the major compounds. Wines fermented with Vinalco yeast presented higher amount of anthocyanins as well as phenolic acids (hydroxycinnamic and hydroxybenozoic) compared to the wines fermented with Lallemand yeasts. The content of malvidin-3-glucoside in Vranec wines fermented with Vinalco yeasts ranged between 235–887 mg/L, whereas Vranec wines fermented with Lallemand yeasts contained 335 to 355 mg/L. The caftaric acid, the main cinnamic acid derivative in all wines, was found in concentration between 176–507 mg/L, followed by coutaric and fertaric acids (14–89 and 11–49 mg/L, respectively). Wines showed relatively high value of the antioxidant activity that ranged between 99–117 mg/L Trolox equivalents, regardless the yeast strain used for fermentation
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
