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
Treatment Outcomes of Myofascial Decompression on Hamstring Pathology
No full textThis study examined the effectiveness of two different hamstring soft tissue treatments; myofascial decompression (MFD) and a moist heat pack with self-myofascial release using a foam roller (SMR). Myofascial decompression, or cupping therapy, is a traditional Chinese therapy that has been adapted to the field of sports medicine. METHODS: This treatment served as the intervention group, a foam roll treatment and heat pack served as the control. Participants consisted of 17 division I student athletes from Oklahoma State University of both male and female genders (4 females and 13 males). All subjects signed an IRB approved consent form prior to any participation. Range of motion measures and a Perceived Functional Ability Questionnaire (PFAQ) scale, to assess patient perception, were used before and after each treatment. The Global Rating Of Change (GROC) scale was completed by all subjects after each treatment to reflect each subject's perception of treatment effect. Subjects were randomly assigned to either the control group (SMR) or the intervention group (MFD). A paired samples T-test was used to determine differences in pre and post measures and a one-way ANOVA was used to compared differences between the two treatment groups. Statistically significant differences were found for range of motions measures regardless of the treatment subjects received. The same was found comparing overall flexibility and comparing the flexibility of the hamstrings on the PFAQ scale. A statistically significant difference was found in favor of the intervention group for the GROC values. The results of this study suggest that either treatment may be beneficial for range of motion increases in patients with hamstring injuries. It also provides a foundation for future researchers inquiring about the clinical effects of myofascial decompression as it pertains to sports medicine. Future research should include a larger patient population and possibly different patient populations. Adding more functional and objective measures may also prove beneficial in future studies to better document treatment outcomes.Education (all programs
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
Effects of a Gluteal Activation Program on Muscle Fatigue and Performance During a 5K Run
No full textStudies show that fatigue causes delayed and decreased muscle activation and motor control in hip musculature during prolonged activity, increasing the risk of injury due to poor joint kinematics and muscle weakness. Previous research has analyzed the intervention of gluteal activation exercises during dynamic and anaerobic activities, but have not investigated the effects of a low-load gluteal activation program during endurance activities. The current study compared hip muscle activity and performance during a controlled 5k run and a run preceded by gluteal activation (GA) exercises. Hip abduction and extension strength were measured before and immediately following a 5k run, while electromyography (EMG) data was recorded in five minute intervals during the run via surface electrodes. Performing GA exercises prior to an endurance run was expected to improve performance and delay muscular fatigue, indicated by a faster performance time and greater and more consistent muscle activation over time compared to a run absent of activation exercises. Results indicated there was no significant difference in muscle activation between condition and time during analysis of five consecutive steps as well as strength at the beginning and end of the run. However, performance was found to significantly improve during the GA condition. Findings may indicate that performing a GA routine prior to activity may promote improved gluteal function, improve performance, and indirectly prevent injury due to improved kinematics and muscular function
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
Comparison of Kinesio Taping and Traditional Non-elastic Prophylactic Ankle Taping on Ankle Range of Motion and Musculotendinous Stiffness in Division I Tennis Athletes
No full textContext: Kinesio tape (KT) is an elastic tape that can be utilized in any phase of injury as an intervention for increasing lymphatic drainage, facilitating or inhibiting muscle activity, providing ligament and tendon support and functional correction. While the KT brand claims to provide patients a variety of therapeutic benefits, there is limited research to support these claims. Objective: The purpose of this study was to compare the effect of KT for functional correction by assisting dorsiflexion (DF) and eversion (EV) and inhibiting plantar flexion (PF) and inversion (IV). Design: Randomized crossover study design. Setting: Clinical setting. Patients/Participants: 19 Division I Tennis Athletes, 10 males and 9 females. Interventions: Participants were randomly assigned to start with no tape (NT), KT or traditional, non-elastic tape (WT) and randomly assigned to start with PF/DF or IV/EV for a one-time test on the Biodex 3 isokinetic dynamometer. Main Outcome Measure(s): Each participant�s range of motion (ROM) and musculotendinous were measured using a Biodex 3 isokinestic dynamometer. Musculotendinous stiffness was calculated as the slope of the angle-torque curve generated by the Biodex 3. Results: No significant difference was found between NT and KT for ROM and MTS in any direction of ankle motion. A significant decrease in ROM was found between NT and WT for PF and EV, as well as MTS of the dorsiflexion muscle group. Significant differences were found between WT and KT for PF ROM and the DF muscle group. Conclusion: Results of this study do not support the claims of KT for functional correction to assist dorsiflexion and eversion and inhibit plantar flexion and inversion. These results do not justify the use of KT as an alternative to traditional, non-elastic prophylactic tape for preventing ankle injuries. Key words: Kinesio tape, musculotendinous stiffness, range of motion, ankle tape, taping, ankle sprains.Health & Human Performance (MS
