The mechanism of fish carbon dioxide anaesthesia to alleviate pain
Get PDF水棲変温動物で鰓呼吸をおこなう魚類における麻酔作用機序は、哺乳類のそれと同じように脳および中枢神経などの神経活動を抑制し、苦痛を軽減しているか不明である。本研究では背地適応し、遊泳能が低く観察しやすい水産重要魚ヒラメをもちい、塩化カリウムによりストレスを人為的に引き起こし、最初のストレス対応である体表色の変化の数値化、つまり「ストレスの可視化」に成功した。そして、塩化カリウムストレス後、種々の麻酔に浸漬したヒラメ既知ストレス因子を調べ、「炭酸が既存麻酔の中で最も魚類のストレスを軽減する」ことを示し、魚類炭酸麻酔作用機序の一端を解明した。It is unclear whether fish reduce the pain same as the anesthetic action (suppress nerve activity such as the brain and central nervous system) of mammal. Because fish are poikilotherm and respirate with the help of gills. In this study, we artificially caused stress in the backland-adapted fish Japanese flounder using potassium. And we succeeded in quantifying the change in body surface color, which is the first stress response. In addition, we investigated well-known stress factors as well. It was clarified that carbonic dioxide anesthesia is the most stress-relieving fish anesthesia.研究課題/領域番号:18K05830, 研究期間(年度):2018-04-01 – 2021-03-31出典：「魚類の苦痛を軽減させる炭酸麻酔の作用機序解明」研究成果報告書 課題番号18K05830

The fish anesthetic: to reduce pain
Get PDF本研究は、魚類への苦痛を抑える麻酔の探索をおこなうとともに、得られた成果を魚類生産現場に普及させることをめざしておこなわれた。ティラピアとトラフグにタブレット型炭酸ガス発泡剤と市販麻酔であるオイゲノールをもちいたところ、ストレス指標は高濃度タブレット型炭酸ガス発泡剤にて低値を示した。通し回遊魚をもちいて麻酔実験をしたところ、タブレット型固形炭酸ガス発泡剤は淡水産卵回遊魚では淡水、海水産卵回遊魚では海水で麻酔に罹りやすいことが示された。以上の結果、タブレット型炭酸ガス発泡剤はオイゲノールよりストレスを低減させる可能性が推察され、通し回遊魚は産卵域の水で炭酸ガス麻酔に懸りやすいことが示唆された。In the present study, we investigated the fish anesthetic to reduce pain, to establish the efficient aquaculture. As the anesthetic effect of published complete genome sequences species, Tilapia and Fugu,using the solid carbon dioxide blowing tablet and the over the counter eugenol, the level of stress marker, glucose etc, are low in the high density of solid carbon dioxide blowing tablet. The high density of solution of carbon dioxide in water using solid carbon dioxide blowing tablet is dependent on its volume, the water temperature and salinity. The anesthetic effect of anadromous fish using solid carbon dioxide blowing tablet are earlier working in fresh water, in contrast these of catadromous fish are earlier working in sea water.These findings suggest that the solid carbon dioxide blowing tablet might be one of suitable anesthetic for fish to reduce stress,and the anesthetic effect of diadromous fish is dependent upon the water conditions of spawning area.研究課題/領域番号:15K07562, 研究期間(年度):2015-04-01 - 2018-03-31出典：研究課題「魚類の麻酔にともなうストレス因子の動態: 苦痛を軽減する魚類麻酔の探索」課題番号15K07562

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
