Sleep Quality in Female Football Players
No full textUvod: San je ključan za fizičko i mentalno zdravlje svih ljudi, a osobito je važan za sportaše jer izravno utječe na sportsku izvedbu, regeneraciju i oporavak. Kod sportaša često se javljaju poremećaji sna, posebice uoči utakmica, što može negativno utjecati na lučenje hormona rasta i sposobnost oporavka. Nogomet, kao intenzivan kontaktni sport, zahtijeva visoku razinu fizičke spremnosti i mentalne stabilnosti. Zbog učestalih ozljeda, osobito mišićnih, zglobnih i ligamentarnih, kvalitetan san jest izrazito važan faktor za prevenciju i rehabilitaciju. Nogometašice su posebno podložne određenim vrstama ozljeda (npr. ozljede prednjeg križnog ligamenta), što dodatno naglašava potrebu za analizom njihove kvalitete sna. Povezanost kvalitete sna s treningom, ozljedama, mentalnim zdravljem i drugim čimbenicima temelj je ovog istraživanja.
Cilj: Cilj ovog rada bio je detaljno ispitati kvalitetu sna nogometašica kroz subjektivnu samoprocjenu. Također se analizirala moguća povezanost između učestalosti i intenziteta treninga te kvalitete sna, kao i prisutnost raznih psihofizičkih simptoma (npr. tjeskoba, razdražljivost, itd.) koji mogu biti povezani s lošim snom. Cilj je ujedno i razumjeti kako navedeni faktori mogu utjecati na sportsku izvedbu i kapacitet oporavka sportašica.
Metode: Istraživanje je provedeno putem anketnog upitnika izrađenog u Google Formsu. U istraživanju je sudjelovalo 30 nogometašica. Anketni upitnik sastojao se od 75 pitanja koja su bila raspoređena u 4 kategorije; 1. Opći podaci i privola, 2. Skala ovisnosti o vježbanju, 3. Skala pobuđenosti prije treninga, 4. Pittsburgh indeks kvalitete spavanja (PSQI) koji je služio za procjenu subjektivne kvalitete sna.
Rezultati: Istraživanje je uspoređeno s nekoliko drugih istraživanja provedenih u različitim sportovima, te u usporedbi s drugim istraživanjima nogometašice imaju bolju kvalitetu sna i manje problema s dnevnom pospanošću. Prosječna duljina stvarnog sna tijekom noći bila je 7 sati te je samoprocjena pospanosti tijekom dana i učestalosti korištenja lijekova za nesanicu bila niska. Kako san ima veliku ulogu kod nogometašica za sportsku izvedbu, ali i brži oporavak, izrazito je važno da ne dođe do pretreniranosti i do smanjene kvalitete sna. Vrlo je važno da nogometašice imaju dovoljno sati stvarnog sna zbog samog normalnog funkcioniranja i bolje sportske izvedbe.Introduction: Sleep is essential for the physical and mental health of all people, and is particularly important for athletes because it directly affects sports performance, regeneration and recovery. Athletes often experience sleep disorders, especially before matches, which can negatively affect growth hormone secretion and recovery ability. Football, as an intense contact sport, requires a high level of physical fitness and mental stability. Due to the frequent injuries, especially muscle, joint and ligament injuries, quality sleep is an extremely important factor for prevention and rehabilitation. Female football players are particularly susceptible to certain types of injuries (e.g. anterior cruciate ligament injuries), which further emphasizes the need to analyze their sleep quality. The connection between sleep quality and training, injuries, mental health and other factors is the basis of this research.
Objective: The aim of this study was to examine in detail the sleep quality of female soccer players through subjective self-assessment. The possible association between training frequency and intensity and sleep quality was also analyzed, as well as the presence of various psychophysical symptoms (e.g. anxiety, irritability, etc.) that may be associated with poor sleep. The aim is also to understand how these factors may affect sports performance and recovery capacity of female athletes.
Methods: The study was conducted using a questionnaire created in Google Forms. 30 female soccer players participated in the study. The questionnaire consisted of 75 questions that were divided into 4 categories; 1. General information and consent, 2. Exercise addiction scale, 3. Pre-training arousal scale, 4. Pittsburgh sleep quality index (PSQI) which was used to assess subjective sleep quality.
Results: The study was compared with several other studies conducted in different sports, and compared to other studies, female soccer players have better sleep quality and fewer problems with daytime sleepiness. The average duration of actual sleep per night was 7 hours, and self-assessment of daytime sleepiness and the frequency of using insomnia medication was low. Since sleep plays a major role in female soccer players for sports performance, but also for faster recovery, it is extremely important to avoid overtraining and reduced sleep quality. It is very important that female soccer players have enough hours of real sleep for normal functioning and better athletic performance
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
