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
The effects of dry needling and radial extracorporeal shockwave therapy on the sensitivity of trigger points in the quadriceps and jump performance: A randomised control trial
Get PDFBackground: Trigger points (TrPs) can reduce strength. Thus, may reduce jump height. Dry needling (DN) is an effective treatment for TrPs but can cause post-needling soreness, potentially reducing jump performance. Radial extracorporeal shockwave therapy (rESWT) is an emerging treatment for TrPs that may not cause post-needling soreness. The post-needing soreness from DN may prevent an athlete training maximally. rESWT may be a possible alternative treatment for TrPs during periods of high-intensity training.
Methods: A mixed absolute intra-class coefficient (ICC[3:1]) was conducted to determine the reliability of the researcher at measuring the pressure pain threshold (PPT), anatomical landmark system (ALS) to locate TrPs. Bland-Altman plots were created to visualise the data. The ICC(3:1) of the countermovement jump (CMJ-JH), jump height of the depth jump (DJ-JH) and components of the DJ was established.
Twenty-one subjects with latent TrPs in the vastus lateralis (VL) and vastus medialis (VM) were treated with DN, rESWT or acted as a control. The outcome measures were the PPT, CMJ-JH and DJ-JH. After a Baseline session (B-line), there were three treatment sessions and two follow-up sessions (FU) at 3-4 days and seven days after the final treatment. A 2-way ANOVA was conducted to determine the effects of DN and rESWT on the PPT of TrPs, in the VL and VM. A 3-way ANOCVA (factoring for PPT) was conducted to analyse the effects of DN and rESWT on CMJ-JH. A 2-way ANOCVA (factoring for PPT and body mass index [BMI]) was carried out to analyse the effects of DN and rESWT on DJ-JH.
Results: The ICC(3:1) for the PPT ranged from 0.637 to 0.875. The ICC(3:1) for the ALS was 0.643 to 0.886 for the X-line and 0.603 to 0.745 for the Y-line. The ICC(3:1) for the CMJ-JH was 0.928 to 0.961. The ICC(3:1) for the DJ-JH was 0.919 to 0.956.
The mean PPT of the DN group increased from 28.25 N to 31.68 N between B-line and FU2. In the rESWT group, the mean PPT increased from 22.08 N to 24.07 N between B-line and FU2. Results from a 2-way ANOVA reported a statistically significant interaction between group and time (p=0.003) for the PPT.
The mean CMJ-JH for the DN group increased from 27.43 cm at the Baseline to 28.07 cm between B-line and FU2; whereas, the rESWT group increased from 23.24 cm to 24.71 cm during the same period. Results from a 3-way ANOCVA (factoring for the PPT) reported a statistically significant interaction between group and time for the CMJ-JH (p=0.007).
The mean DJ-JH for the DN group decreased from 22.71 cm to 20.86 cm between B-line and FU2. The rESWT group also decreased, from 21.38 cm at Baseline to 20.21 cm at Follow-up 2. A 3-way ANOCVA (factoring for the PPT and BMI) reported a statistically significant interaction between group and time for the DJ-JH (p=0.001).
Conclusion: The investigator is reliable at measuring the PPT, ALS, CMJ-JH, DJ-JH. DN appears to have a positive effect on the mean PPT after one week once the post-needling soreness had subsided. rESWT shows a gradual improvement in PPT and CMJ-JH throughout the treatment phase and follow-up phase, which suggests that rESWT does not cause post-treatment soreness. Treating subjects with DN may not be the most appropriate action if they are engaging in competition or high-intensity concentric strength training in the following week. DN and rESWT can impede reactive strength for up to four days, possibly due to reducing the elastic property of the taut bands associated with TrPs. Further studies should include treating multiple TrPs in multiple muscles involved in triple extension and measuring muscle activation. Future research in this area should also consider using a longer post-treatment follow-up period.ye
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
The immediate and sustained effects of mobilisations with movement on the hip range of motion and power and shoulder range of motion and strength
No full textIntroduction. The purpose of this study was to determine the effect of a mobilisation with movement (MWM) and self-applied mobilisation with movement (SMWM) treatment on hip extension ROM (°), jump height (cm) and power (N) output and shoulder ROM (°) and strength [Peak Torque per Body Weight (%) and Time to Peak Torque (ms)]. Studies have demonstrated that MWM treatment has an effect on shoulder IR ROM and isometric strength, however no previous study has determined the effect of a MWM and SMWM treatment on shoulder rotational ROM or isokinetic strength. While MWMs have been shown to significantly increase functional hip IR ROM, no previous research has explored the effects of MWM or SMWM treatment on hip extension. Previous studies have documented an increase in isometric muscle strength following hip mobilisations, however no research to date has explored the effects of MWM and SMWM treatment on hip power. Similarly, previous studies demonstrated an increase in isometric muscle strength following shoulder mobilisations, however no research to date has explored the effects of MWM and SMWM treatment on isokinetic shoulder rotational strength.
Methods. The first study investigated the effect of a single MWM and SMWM treatment bout on the hip joint (n=60), where the treatment effects where examined immediately, 24hrs and 48hrs post. The participants had a restricted hip extension ROM (<20°). Baseline hip extension ROM (°) and hip power [jump height (cm) and power (N)] measures were obtained with a mobile phone inclinometer and a force plate. The participants were stratified and randomly allocated into groups; therapist applied MWM (n=20), self-applied MWM (n=20) or the control (n=20). The participants received treatment on the hip joint based on their respective group. Participants only received a single treatment application (3 sets of 10 repetitions). Outcome measures were reassessed immediately, 24hrs and 48hrs following the treatment application. The second study investigated the treatment effects of a single MWM and SMWM treatment bout immediately, 24hrs and 48hrs post treatment on the shoulder joint (n=73). Participants had a restricted shoulder IR ROM (<60°). Baseline shoulder IR ROM (°) and strength measures [Peak Torque per Body Weight (%) and Time to Peak Torque (ms)] were obtained using an inclinometer and an isokinetic Biodex Machine respectively. The participants were stratified and randomly allocated into groups; therapist applied MWM (n=19), self-applied MWM (n=21) or the control (n=22). The participants received treatment on the shoulder joint based on their respective group. Participants only received a single treatment application (3 sets of 10 repetitions). Outcome measures were reassessed immediately, 24hrs and 48hrs following the treatment application. The third study investigated the effects of multiple MWM and SMWM treatment applications immediately and up to 7 days post treatment (n=27). Participants had a restricted shoulder IR ROM (<60°). Baseline shoulder IR ROM (°) and strength measures [Peak Torque per Body Weight (%) and Time to Peak Torque (ms)] were obtained using an inclinometer and an isokinetic Biodex Machine respectively. The participants were stratified and randomly allocated into groups; therapist applied MWM (n=9), self-applied MWM (n=9) or the control (n=9). The participants received treatment on the shoulder joint based on their respective group. Participants received 3 treatment applications (3 sets of 10 repetitions in each treatment application) over a period of a week. Outcome measures were reassessed immediately, 48hrs and 7 days following the final treatment. The data was analysed using the SPSS statistics package, the between group differences were compared using a split plot ANOVA with the post-hoc analysis and the paired t-test was utilised to identify within group changes.
Results. In study one, a split plot ANOVA revealed no significant between group effects for hip ROM or hip power immediately, 24hrs or 48hrs post treatment when compared to the baseline measurement. In study two, a split plot ANOVA revealed a significant between group effect (F=5.09 [df=2, SE=47], p=0.01), demonstrating a significant increase in the MWM and SMWM groups immediately (MWM=11°,SMWM=10°), 24 hours (MWM=8°,SMWM=8°) and 48 hours (MWM=7°,SMWM=6°) post treatment when compared to the baseline measurement. In study three, a split plot ANOVA revealed a significant between groups effects (F=8.4 [df=2, SE=27], p=0.01), demonstrating a significant statistical difference in the MWM and SMWM groups immediately (MWM=14°,SMWM=13°), 48 hours (MWM=13°,SMWM=15°) and 7 days (MWM=18°,SMWM=14°) post treatment when compared to the baseline measurement. No significant between group effect was found for shoulder ER ROM and strength measures for both SMWM and MWM in study two and three.
Conclusion. A single application of MWM and SMWM techniques did not significantly effect hip ROM, jump height or power output. A single application of MWM and SMWM treatment is equally effective at increasing shoulder IR ROM immediately and up to 48h post treatment application. Multiple MWM and SMWM treatments are effective in increasing shoulder IR ROM immediately and up to 7 days following the treatment application, furthermore it results in a greater ROM increase when compared to a single treatment application. The application of MWM or SMWM treatments has no negative impact on shoulder strength or shoulder ER ROM.ye
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
