Possible approaches to the study of the emissions from ships during their operations in ports
No full textThe quality of the air close to big ports mainly depends on the emissions from ships. Although it is difficult to determine emissions from ships, improving the assessment of these emissions could help port management to find logistic solutions that can contain the effect of the concentration of many large ships in small spaces. In this paper, a new research group will be presented: The cooperation between the University of Naples and Istanbul Technical University will be focused on the study of ship emissions in port. The paper will represent the starting point of these shared research activities; it will try to develop a methodology for estimating, measuring, and validating emissions in ports of the two areas
Possible approaches to the study of emissions from ships during their operations in ports
No full textThe emissions from ships are the key factor influencing the air quality near large ports. Although ship emissions are difficult to quantify, doing so can help port management find logistical solutions that can reduce the impact of having a large number of giant ships in a limited space. The joint study between the University of Naples and Istanbul Technical University, which focuses on the investigation of ship emissions in ports, is presented in this paper. It is expected that this study will lead to create new techniques for calculating, measuring, and validating emissions from ships at ports
Yetersiz Beslenmenin Ve Sonras?ndaki Rehabilitasyonun Gen? Ergin S??an Cerebellar Korteksindeki Etkileri

Ergin S??an Cerebellar Korteksindeki Etkileri Bu ?al??mada baz? s??anlar, 105 ve 134. g?nler aras?nda, dene/ boyunca iyi beslenen s??anlar?n alm?? olduklar? besin miktar?n?n % 50' si verilmek suretiyle yetersiz beslenmi?lerdir. Bunun yan?nda baz? s??anlar yetersiz besleme periyodunun bitiminden itibaren k?s?tlamas?z besin al?m? sa?lanmak suretiyle 175. g?ne kadar besin rehabilitasyonu g?rm??lerdir. 134. g?nde yetersiz beslenmi? s??anlar?n v?cut a??rl??? kontrol ya??tlar?na g?re ?nemli derecede az bulunmu?tur. 175. g?n sonunda bu kay?p giderilememi?tir. Herbir ya?ta, kontrol ve deney gruplar? aras?nda cerebellum ve ?nbeyin a??rl?klar?, Nvg, Nvp, Nvs, G/P ve S/N de?erlerinde fark g?r?lmemi?tir, fakat 134 ve 175. g?nler aras?nda kontrol hayvanlar?n v?cut ve cerebellum a??rl?klar?, Nvs ve S/N de?erleri ?nemli derecede artm??t?r. Di?er taraftan, 134 ve 175 g?nl?k deney grubu s??anlar aras?nda Purkinje h?cresi n?kleus ?ap? ?nemli derecede azalma g?sterirken, v?cut, cerebellum ve ?nbeyin a??rl?klar? ile Nvg ve Nvs ?nemli art??lar g?sterilmi?tir. Sonu? olarak, bizim sonu?lar?m?z gen? ergin s??an cerebellar korteksinin yetersiz beslenmeye kar?? diren?li oldu?unu g?stermi?tir. Bununla birlikte gran?l h?cre tabakas?ndaki sinaps densitesi ya?la birlikte ?nemli bir art?? g?stermi?tir
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
