No full textGoing 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
Effect of segmental muscle vibration on upper extremity functional ability poststroke: A randomized controlled trial.
Full text linkAbstract
Background: Upper extremity functional impairments are common consequences of stroke. Therefore, continuous investigation
of effective interventions for upper extremity functions after stroke is a necessity. Segmental muscle vibration (SMV) is one of the
interventions that incorporate sensory stimulation to improve motor cortical excitability. The aim of this study was to investigate the
influence of 5-minute SMV application along with supervised physical therapy (SPT) on improving activities of daily living and motor
recovery on the hemiparetic upper extremity in patients with stroke.
Methods: A sample of 37 patients poststroke (29 males) was randomly allocated to either SPT control group (n=18) or SPT and
SMV (SPT-SMV) experimental group (n=19). All patients received 3 sessions per week of SPT for 8 weeks. The SPT-SMV
experimental group received SMV at the end of each SPT session. Outcome measures used were Barthel index (BI), modified
Ashworth scale, manual muscle testing, and goniometry for range of motion (ROM) assessment.
Results: Thirty-four patients completed the study. Patients in both groups improved significantly after treatment in BI, elbow ROM,
and elbow muscles strength. However, muscle tone in elbow joint of the hemiplegic upper extremity improved significantly after SMV
only in the experimental group (SPT-SMV).
Conclusion: The SPT intervention can improve functional outcomes of upper extremity in people after stroke. However, using SMV
may have superior effect on improving muscle tone after stroke.

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
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
Noninvasive brain stimulation for cognitive rehabilitation following traumatic brain injury: A systematic review
No full texttraumatic brain injury (TBI) can cause numerous cognitive deficits. these deficits are associated with disability and reduction in quality of life. noninvasive brain stimulation (NIBS) provides excitatory or inhibitory stimuli to the cerebral cortex. this review aimed to examine the effectiveness of NIBS (i.e., rTMS and tDCS) on cognitive functions in patients with TBI. pub med, SCOPUS, PEDro, CINAHL, MEDLINE, REHABDATA, and web of science were searched from inception to may 2021. the risk of bias in the randomized controlled trials was assessed using the cochrane collaboration's instrument. the physiotherapy evidence database (PEDro) scale was applied to evaluate the risk of bias in the non-randomized controlled trials. ten studies met our inclusion criteria. six studies used repetitive transcranial magnetic stimulation (rTMS), and four used transcranial direct current stimulation (tDCS) as cognitive rehabilitation interventions. the results showed heterogenous evidence for the effects of rTMS and tDCS on cognitive function outcomes in individuals with TBI. The evidence for the effects of NIBS on cognition following TBI was limited. TDCS and rTMS are safe and well-tolerated interventions post-TBI. the optimal stimulation sites and stimulation parameters remain unknown. combining NIBS with traditional rehabilitation interventions may contribute to greater enhancements in cognitive functions post-TBI
Virtual reality for balance and mobility rehabilitation following traumatic brain injury: A systematic review of randomized controlled trials
No full textBackground: Balance and mobility deficits are most prevalent impairments in patients with traumatic brain injury (TBI). The evidence has proposed that rehabilitation plays an important role in improving balance and mobility post-TBI. Virtual reality (VR) is a computer technology that provides immersed users to generate feedback such as visual, audio, and haptic. Objective: This review aimed to examine the effects of the VR treatment intervention on balance and mobility in patients with TBI and to define the most effective VR treatment protocol. Methods: SCOPUS, PEDro, PubMed, REHABDATA, EMBASE, and the web of science were searched for experimental trials examining the impacts of VR training on balance and mobility in patients with TBI from inception until July 2022. Physiotherapy Evidence Database (PEDro) scale was used to assess the methodological quality of the selected studies. Results: Five randomized controlled trials (RCTs) met the inclusion criteria. The PEDro scores ranged from 6 to 8, with a median of 6. A total of 157 patients with TBI were included in this review, 31.2% of whom were females. The findings showed that VR intervention is not superior to traditional physiotherapy interventions in improving balance and mobility post- TBI. Conclusions: The preliminary findings showed that the influence of VR on the balance and mobility ability in patients with TBI is promising. Combining VR with other concurrent rehabilitation interventions may show more significant improvements in balance and mobility compared to VR interventions alone. The optimal VR treatment protocol remains unclear. Further randomized controlled trials are strongly needed
