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

Thus circulating OPG may be an uremic toxin to develop uremic bone and parathyroid diseases through increasing skeletal resistance to PTH. Ji Shui Tan Hospital Objectives: To observe change of the serum TNF-alpha concentration when patients with osteodystrophy have been treated by 1-alpha(OH)D3. Methods: Twelve patients with chronic renal failure and renal osteodystrophy treated with 1-alpha(OH)D 3 , 0.5µg /day for 2 weeks and 4 weeks individually. Results: The serum TNF-alpha concentration descended obviously after 1-alpha(OH)D3 treatment. Conclusions: 1-alpha(OH)D3 may regulate TNF-alpha producting and secreting in mononuclear leukocyte. Objective To investigate the characteristic of bone metabolism in type 2 diabetes mellitus. Methods The levels of serum 25OHD, IBGP and urine HOP, Crosslaps were determined in 64 type 2 diabetes mellitus patient. Results (1) The levels of serum 25OHD in type 2 diabetes mellitus group were lower than that in normal controls (Male and premenopause women vs controls P0.05). The relevant analysis suggests there was no significant relativity among age | duration of diabetes and the BMD | serum BGP | ALK-B | Pyr-D | calcium | phosphorus and urine calcium in diabetic group. There were obvious positive relations between bodyweight index and serum phosphorus and BMD (P<0.05 and P<0.01). Conclusions: Low body weight is a risk for diabetic patients to get OP. BMD in diabetic patients is a bit higher than in normal elder, but no significant difference. The nature of ectopic bone and depositions of amorpheous calcifications in advanced atherosclerosic lesions is not well understood. Accumulating evidence suggests that atherosclerotic calcification shares features with bone calcification. We studied the presence of osteoprotegerin (OPG) and osteoprotegerin ligand (OPGL) in ectopic bone and amorpheous calcifications of type Vb human atherosclerotic lesions derived from the abdominal aorta. The localization of OPG and OPGL was determined by immunohistochemistry in 5 patients with ectopic bone formation (Group 1) and in 7 patients with amorpheous calcified depositions without bone structure (Group 2). In group 1, areas of lamellar bone were found containing lining cells, osteoblasts, osteoid, trabecular bone with cement lines, osteocytes and osteoclasts. In some areas cartilage structures were found containing matrix, lacunas and chondrocytes. In group 2, amorphous calcium deposits were found. OPGL was absent in and around the bone matrix in group 1. Faint OPGL depositions were close to areas of inflammation, which included T cells. In the lesions with cartilage structure, no OPG or OPGL could be identified. In group 2, deposition of OPGL was found in areas immediately around amorphous calcium depositions. OPG was found in the lining cells and in some of the smooth muscle cells in group 1 but could not be detected in group 2. These results indicate that OPG and OPGL are involved in ectopic bone formation and in the deposition of amorpheous calcium in atherosclerosis. This could provide a base for the study of the effect of bone-specific agents on the progression of atherosclerosis. Inflammatory Bowel Disease (IBD) is often followed by a loss of bone mass and bone quality. The resulting metabolic osteopathy should be characterized using laboratory and bone histomorphometric parameters. We investigated 19 patients (9 men, 10 women, age 23-68 years) suffering from Crohn's disease (16) or ulcerative colitis (3). The mean duration of the disease was 5,2 years (0,5-23). At the time of investigation, 16 patients were treated with corticosteroids (for a mean of 1,9 ys.). As serologic parameters we determined ESR, CRP, calcium, 25-OH-vitamin-D3, PTH and osteocalcin. After tetracycline labelling, bone biopsies were taken from the right anterior iliac crest applying a vertical technique. The samples were embedded in methylmetacrylate, sectioned on a heavy-duty microtome and stained (Masson-Goldner, Gomori, Giemsa). The following histomorphometric parameters were obtained using a Merz grid: bone volume (BV, in % of total bone volume), osteoid surface (OS), eroded surface (ES), osteoblast-(ObS) and osteoclast-covered surface (OcS), mineralized surface (MS, each in % of bone surface) and mineral apposition rate (MAR in microm). Patients with IBD showed increased CRP-levels (30,2±39,1 mg/l) and normal levels of calcium (2,32±0,21 mmol/l), 25-OH-vitamin-D3 (20,0±10,3 ng/ml) and PTH (25,6±10,9 ng/l), with a tendency towards low osteocalcin-levels (5,7±3,1 ng/ ml, reference 5-12). Histomorphometric parameters of IBD-patients were as follows (reference value of healthy young adults in parenthesis): 0,73±0,29microm (0,75). Osteopathy in IBD may be caused by a reduced calcium and vitamin-D resorption, the systemic action of inflammatory cytokines and the effect of corticosteriod treatment on bone. The normal levels of calcium, vitamin D and PTH in our patients do not support the hypothesis of a calcium deficiency as a main pathogenetic aspect. Small osteoid surface and low osteocalcin levels reflect a reduced bone formation, which is likely to be caused by the effects of corticosteriods on bone. In contrast, both the elevation of eroded surface and osteoclast-covered bone surface point to an increased bone resorption. According to our histomorphometric parameters, reduced bone formation and increased bone resorption seem to be characteristic features of osteopathy in patients with IBD

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
