Qualitative assessment of progressive addition lenses (PALs) prescription / Rabiatun Mujari
Get PDFIntroduction: Progressive additional lenses (PALs) are increasingly preferred mode for the correction of presbyopia. The objectives of this study were to determine PALs wearer perceived quality of vision as total satisfaction and to assessed the correlation of quality of vision and symptoms reported with total satisfaction level of PALs delivered by UiTM Vision Care. Material and methods : This study was a cross sectional survey. Thirty-two respondents from target population were recruited respectively. A self-administered questionnaire was given to respondents. The questionnaires was adopted from The Ohio State University to evaluate the satisfaction level of visual performance using the in the respondent‟s daily living activities. The quality of vision includes the questions regarding distance viewing, intermediate viewing, near viewing and mobility. Each question was scored based on a Likert scale ranging from 0 to 10. Results : Result showed there was high positive and significant correlation in all quality of vision with total satisfaction as well as the symptoms reported among PALs wearers with total satisfaction. The highest significant correlation was found in intermediate viewing which seeing computer screen and seeing grocery shelves. Blurred vision showed lowest correlation among other symptoms reported. Slopes of the regression lines for each task are positive. For the correlation of symptoms reported with total satisfaction, results showed high correlation of symptoms reported with total satisfaction. Results showed no significant differences between the symptoms indicates PALs wearer able to adapt and can use PALs without any significant visual problems in their daily activities. Conclusion : In conclusion, most of PALs wearer dispensed by UiTM Vision Care showed high level of satisfaction with the PALs dispensed and experienced less symptoms associated with the PALs. PALs wearers can easily adapt to and use PALs without significant visual problems during daily activities
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
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
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
Perbedaan Pengaruh Metode Recovery Pasca Latihan Maksimal Terhadap Kadar Asam Laktat Ditinjau Dari Jenis Kelamin (studi eksperimen metode active recovery dan cold bath pada atlet bolavoli)
Get PDFABSTRAK Wahyana Mujari Wahid. A121508057. 2017. “PERBEDAAN PENGARUH METODE RECOVERY PASCA LATIHAN MAKSIMAL TERHADAP KADAR ASAM LAKTAT DITINJAU DARI JENIS KELAMIN (Studi Eksperimen MetodeActive Recovery dan Cold Bath Pada Atlet Bolavoli)”. TESIS. Pembimbing I: Prof. Dr. Muchsin Doewes, dr., SU, AIFO, MARS, Pembimbing II: Prof. Dr. Siswandari, M. Stats. Program Studi Ilmu Keolahragaan, Pascasarjana Universitas Sebelas Maret Surakarta. Penelitian ini bertujuan untuk mengetahui: (1) Perbedaan pengaruh active recovery dan cold bathterhadap kadar asam laktat. (2) Perbedaan kadar asam laktat antara laki-laki dan perempuan. (3) Pengaruh interaksi antara metode recovery (active recovery dan cold bath) dan jenis kelamin terhadap kadar asam laktat. Penelitian menggunakan metode eksperimen dan desain penelitian menggunakan rancangan faktorial 2 X 2. Adapun latihan maksimal yang diberikan adalah sprint 400 m. Populasi dalam penelitian ini adalah atlet Persatuan Bolavoli Seluruh Indonesia (PBVSI) Kabupaten Magetan dengan jumlah 32 atlet yang terdiri dari 16 atlet putra dan 16 atlet putri. Teknik sampling yang digunakan adalah tekniktotalsampling. Sampel kemudian dibagi berdasarkan eksperimen, 8 atlet laki-laki dilakukan latihan maksimal dan active recovery, 8 atlet laki-laki dilakukan latihan maksimal dan cold bath, kemudian 8 atlet perempuan dilakukan latihan maksimal dan active recovery, 8 atlet perempuan dilakukan latihan maksimal dan cold bath. Variabel yang diteliti yaitu variabel bebas terdiri dari dua faktor yaitu variabel manipulatif dan variabel atributif, serta satu variabel terikat. Variabel manipulatif terdiri dari active recovery dan cold bath. Variabel atributif terdiri dari kelompok sampel dengan jenis kelamin laki-laki dan perempuan. Variabel terikat pada penelitian ini yaitu kadar asam laktat. Pengambilan data kadar asam laktat dilakukan dengan menggunakan Accu-check lactic acid. Teknik analisis data pada penelitian ini menggunakan analisis Two Way Analisis of Variance (ANOVA Dua Jalan), pada taraf signifikansi 5%. Berdasarkan penelitian yang dilakukan diperoleh hasil yaitu: (1) Ada perbedaan pengaruh yang signifikan antara active recovery dan cold bath terhadap kadar asam laktat, dimana diperoleh Fobservasi sebesar 45.96 dan nilai p = 0.00 (P0.05). Baik kelompok laki-laki maupun perempuan memiliki penurunan/perubahan kadar asam laktat darah yang tinggi dengan pemberian metode recovery cold bath. Berdasarkan hasil penelitian dan pembahasan dapat ditarik kesimpulan bahwa: (1) Ada perbedaan pengaruh yang signifikan antara metodeactive recovery dan cold bath terhadap kadar asam laktat. Metode cold bath lebih baik dibandingkan dengan metodeactive recovery dalam menurunkan kadar asam laktat. (2) Ada perbedaan kadar asam laktat antara laki-laki dan perempuan. Laki-laki lebih cepat dalam penurunan/perubahan kadar asam laktatdibandingkan perempuan. (3) Tidak ada pengaruh interaksi antara metode recovery dan jenis kelamin.
