The Effect of Proprioceptive Neuromuscular Facilitation to Cervical Spine Posture in Road Cyclists
No full textAuthor: Bc. Hana Bezděková Title: The Effect of Proprioceptive Neuromuscular Facilitation to Cervical Spine Posture in Road Cyclists Objectives: The aim of this diploma thesis is to assess the effect of 6 weeks proprioceptive neuromuscular facilitation theraphy on posture of the cervical spine in road cyclists. Methods: This is a quaziexperimental study with general noninvasive examination. Photogammetry was used for evaluation of posture of the cervical spine and craniocervical flexion test was used to assess strength in deep neck flexors. The group that was examined consisted of 8 men and 2 women. Statistical analysis was performed using Shapiro-Wilk test, coupled t-test and regression. The siginificance level was set to α = 0,05. Cohen's d test was used to verify material significance. Results: There was no statistical and effect size significance found in input and output difference of craniovertebral angle in the experimental group after 6 weeks of PNF exercises. On the other hand, we have proven the statistical and effect size significance in strenght of deep cervical flexors before and after PNF treatment. Road cyclists are also, proportionally to time spent road cycling, more vulnerable to forward head posture. Keywords: proprioceptive neuromuscular facilitation, road cyclists, cervical spin
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

Hana Bezděková Název: Efekt proprioceptivní neuromuskulární facilitace na postavení krční páteře u silničních cyklistů Cíl: Cílem diplomové práce bylo zhodnocení efektu šestitýdenní terapie vybraných prvků proprioceptivní neuromuskulární facilitace na postavení krční páteře u silničních cyklistů. Metody: Jedná se o kvaziexperimetální studii s použitím objektivního neinvazivního vyšetření. Pro hodnocení postavení krční páteře bylo vybráno pomocí fotogrammetrie měření kraniovertebrálního úhlu volně přístupným softwarem Kinovea®, jako hodnotící prostředek síly hlubokých flexorů krku byl vybrán kraniocervikální flekční test. Výzkumný soubor tvořilo 8 mužů a 2 ženy. Ke statistickému zpracování dat byl zvolen Shapiro-Wilkův test, párový t-test a regresní a korelační analýza. Pro statistické testy byla nastavena hladina významnosti α = 0,05. K ověření věcné významnosti byl použit test Cohenova d. Výsledky: U výzkumného souboru silničních cyklistů nedošlo po 6 týdnech cvičení PNF ke statisticky ani věcně významnému rozdílu mezi vstupní a výstupní hodnotou kraniovertebrálního úhlu. Bylo statisticky potvrzeno, že cvičení PNF má pozitivní efekt na zvýšení síly hlubokých flexorů krku. Zároveň jsou silniční cyklisté úměrně ke zvyšující se době, s jakou se věnují silniční cyklistice, náchylnější k...Sporty v příroděFaculty of Physical Education and SportFakulta tělesné výchovy a sport
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
