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
EXERCISE IN FORWARD HEAD POSTURE AND ROUNDED SHOULDER: STRETCHING OR STRENGTHENING?
Get PDFObjective: To determine the effects of stretching and strengthening exercises on asymptomatic adults diagnosed with forwarding head posture and rounded shoulders.Material & Methods: A randomized controlled trial was conducted after the screening and confirmation of FHP and RS by measuring craniovetrebreal angle (CVA) and shoulder angle (SA) using Kinovea Software, 34 Patients were inducted into trial through consecutive sampling, with17 patients in each of 2 groups i.e. “A” and “B”. Subjects were distributed into two groups equally; Group A received a strengthening exercise approach and Group B received a stretching exercise approach. Data was analysed using SPSS version25.Results: There was a statistically significant difference (p-value < 0.001) in pre-and post-treatment CVA and SA within each treatment group. However, no significant difference (p-value > 0.05) was reported across each treatment while comparing pre-and post-treatment values for CVA and SA respectively.Conclusion: Stretching and strengthening exercises are equally effective in the management of FHP and RS posture in asymptomatic individuals. However, strengthening exercise showed superior improvement in CVA and SA comparatively
Effects of physical environment factors on worker's health in micro and small sized industries of Pakistan
Get PDFBackground: Physical and environmental factors can affect both job performance and job satisfaction of the workers. Despite of the progress and improvement made for occupational safety and health, work environment especially in low and middle income countries is still hazardous for the workers. A large number of work related injuries and occupational accidents happens around the world each year. This research project aims to map work environment conditions and impact of physical environmental factors on occupational health in Punjab – Pakistan. Methods: Total eight micro and small industries in Lahore and Gujaranwala were visited during winter and summer season separately. Physical factors of light, noise and temperature were recorded for six hours during winter. A quantitive questionnaire was filled from 138 workers and an inspection of workplace was made by using ILO ergonomics checklist. Modified Testo 177 and Lascar data loggers were used to measure air (ta), globe (tg), natural wet bulb (tnw) temperatures and relative humidity (RH) to calculate the WBGT index. Result: Mean age of workers was 28.6 ± 10.5 years working for 8.8 ± 1.5 hours a day at a metabolic rate of 165 W/m2 (ISO 7243 level of exertion) and had 0.5 – 1 hour rest. In cold season the average indoor WBGT was 16.0 ± 2.5 ºC and in hot season the average indoor WBGT was 29.9 ± 5.5 ºC and indoor air velocity was 0.7 ± 0.3 m/s. Noise was recorded for time weightage average (TWA) and recorded a range of 73.1 dB (A) to 91.7 dB (A). Minimum intensity of 41.5 lux for light was recorded in one industry. Conclusion: A noise level of less than 85 dB (A) and light of 400 lux to 800 lux will improve physical and psychosocial work environment. Heat stress monitoring policy can be implemented by using ISO 7243. ILO ergonomic checklist can prove an important tool to make assessment and recommendations for working environments in Pakistan.

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
