Workplace stress and musculoskeletal disorder: The relative roles of psychosocial and physical risk factors / Muhammad Afdhaluddin Muhammad Adib
Full text linkWork related musculoskeletal disorders (WRMSD) have been reported by many people from all over the world. The direct as well as indirect costs associated with WRMSD as for the compensation purpose is relatively high in value and the effect of it both to the employees and companies are very much significant. Major research studies have only concentrated on the effect of ergonomics to WRMSD. However, more researches have come into surface for the study of the relationship between psychosocial stress factors at workplace with WRMSD. In this research study, there are 6 variables under the psychosocial risk factors which being set and determined as independent variables whereas WRMSD being set as dependent variable. The 6 factors mentioned here are job demand (JD), role expectation (RE), work control (WC), social interaction (SI), leadership influence (LI), as well as organizational culture (OC). A total of 50 sample sizes have been taken and the correspondents comprised of employees working in the shared service companies located in Kuala Lumpur and Selangor. A set of questionnaire which been used as the main tool in this study as has been distributed to all correspondents and explanations on how to answer it have also been given accordingly. Two type of questionnaire being used merged into one are : part 1 (QPS-Nordic questionnaire) and part 2 (Standardized Nordic questionnaire for musculoskeletal symptoms). Quantitative analysis has also been used for this study where out of the 6 factors, 4 risk factors have shown positive relationship with WRMSD. The 4 factors are JD (χ2=15.111, DF=2, P<0.05), RE (χ2=15.130, DF=2, P<0.05), WC (χ2=6.106, DF=2, P<0.05) and OC (χ2=9.051, DF=2, P<0.05). It is believed that by the effectiveness of recommendations given at the end of this studies may help to cope and eventually minimizing WRMSD at the workplace
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
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
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

Rancang Bangun Jaringan Fixed WiMAX IEEE 802.16d untuk Layanan Mobile VoIP Codec ITU-T G.729
Full text linkWorldwide Interoperability for Microwave Access (WiMAX) IEEE 802.16d merupakan salah satu teknologi yang mampu memberikan layanan data dengan kecepatan tinggi dan efisien. WiMAX menyediakan kecepatan data hingga 40 Mbps. Salah satu keunggulan WiMAX adalah menawarkan Quality of Service (QoS) berbeda. Salah satunya adalah QoS varian real-Time Polling Service (rTPS) untuk layanan Voice over Internet Protocol (VoIP). Kemudian terdapat pula tipe QoS varian Best Effort (BE) yang dirancang untuk penggunaan jaringan WiMAX sebagai jaringan backhaul. Penelitian ini bertujuan untuk membangun prototipe komunikasi VoIP yang memiliki bandwidth kompresi hingga 8 kbps tiap kanal suara dengan cara menggabungkan Teknologi VoIP dengan jaringan WiMAX. Dan dapat menganalis kinerja jaringan VoIP melalui parameter jaringan, yakni throughput, delay end-to-end, jitter. Serta menganalisis kapasitas trafik jaringan WiMAX sebagai jaringan backhaul untuk layanan VoIP Codec ITU-T G.729. Jumlah client VoIP yang dilibatkan sebanyak 14 handset Android dan 1000 client yang dibangkitkan oleh perangkat call generator. Adapun teknologi kompresi yang digunakan ialah codec G.729 dan sebagai perbandingan digunakan pula jenis codec G.711. Hasil penelitian menunjukkan nilai throughput relatif stabil dengan semakin banyak jumlah user maka throughput akan semakin kecil. Hasil untuk delay didapatkan nilai tertinggi ialah 21,819 ms untuk G.711 dan 13,889 ms untuk G.729. Dan nilai tersebut tergolong kategori baik menurut standar ITU-T G.114. Kemudian nilai jitter tertinggi yang didapat ialah 10,497 ms untuk G.711 dan 10,323 untuk G.729. Dan hasil ini menunjukkan nilai yang baik menurut standar ITU-T Y.1541. Kapasitas trafik pada jaringan backhaul yang didapat ialah 400 client pada kapasitas kanal 25,4 Mbps dengan rentang nilai Grade of Service (GoS) di antara 0 – 3,589%
