Injury status among secondary school rugby players / Muhamad Fakhrul Hakim Azis
Get PDFThe purpose of this study is to investigate the overall injury status among secondary school
rugby players in Malaysia. There were 150 rugby players aged between 13-18 years old who
were selected and they were categorized based on their playing positions in rugby namely
forward (n=75) and backline position (n=75). The specific aims of this study are to
determine the frequency the nature of injury among forward and backline positions, to report
the common incidence sites of injury and the aetiology of injury among secondary school
rugby players in Malaysia and Chi-Square Test has been utilized to interpret the data in order
to meet the objectives of this study. The results showed there is no association (p>O.05)
on frequency of nature of injury based on playing position. Meanwhile, the region
with highest injury rate from this finding was lower body with the value of 84.7%
(n=127) and for the mechanism of injury, there were significantly more injuries
occurred in youth rugby player during contact 96.7% (n=145) compared with noncontact
64.7% (n=97) and climate 9.3% (n=14)
A 4-week internal training load monitoring and fatigue responses of malaysian under-18 rugby players during competitive season
Get PDFMonitoring internal training loads using session ratings of
perceived exertion (RPE) has been used extensively to manage fatigue and to
optimise sports performance in athletes but none was reported in Malaysian
athletes. Accurate monitoring of internal training loads could assist coaches in
the adjustment of training, mode, intensity and duration during the competitive
season. This study was to quantify the internal training loads (training load,
monotony and strain) and fatigue and to identify the correlation of internal
loads on fatigue responses of Malaysian under-18 rugby players for 4-weeks
during competitive season. Thirty eight male participants of the study, aged from 16-18 years
old, were recruited among the students from the Kolej Vokasional Pengkalan
Chepa (N=38). The research variables of this study were collected in four
weeks prior to their competition. After 90 minutes of every training session,
they were asked to rate their training session using the RPE scale. Then, the Multidimensional Fatigue Symptom Inventory (MFSI)-Short form were administered once per week at the end of their training session for 4 weeks. The participants were trained five days per week as per coach’s training programme, hence the total number of days of data collection were 20 days.
The types of training consisted of cardiovascular, strength, power and tactical.
All data was entered into Microsoft Excel 2013. Statistical analyses was
performed using IBM SPSS version 24.0. All data are presented as mean �}
standard deviation (SD) in descriptive statistics. The statistical analysis used in
this study was repeated measure ANOVA. The statistical significance was set
0.05. Pearson correlation at p was used to analyse the relationship between
internal training load variables and MFSI. Results showed that the training load in week 4 (2594.00 �} 2.30) was
significantly higher compared to week 1 (2388.55 �} 343.87), week 2 (2284.34 �}
411.41) and week 3 (2218.42 �} 521.63). Monotony in week 4 was higher (1.70 �}
3.13) compared to week 3 (1.43 �} 0.44). The mean of monotony in week 2 was
higher (1.60 �} 0.35) than week 1 (1.49 �} 0.09). Strain increased in week 2 was
higher (3728.44 �} 1228.51) compared to week 1 (3605.57 �} 653.51). In week 3,
the mean strain decreased (3354.59 �} 1810.58) and increased in week 4 (4145.66
�} 306.38). In training load, monotony, strain and the total score of fatigue (TSF)
correlation, the result showed that training load increased with moderate
correlations to TSF (r=0.342; r=0.402; r=0.469). In monotony (r=354; r=0.371;
i=0.421) and strain (r=0.343; r=0.383; r=0.446), there were also moderate
correlation to TSF. The results obtained in this study will help the coaches and
trainers to develop an effective training programme in order to maximise their
athlete’s performance, reduce fatigue and subsequently prevent injuries
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
