Noise is an environmental pollutan. It may disturbs the function of some endocrine glands. The aim of this study is to explore the effect of noise at thyroid and the high f oliculli epithelium cell and body weigth of female mice (Mus musculus).
This study using females mice (Mus musculus) which were devided into three groups, i.e. control group, noise induction at 90-94 dB group and noise induction at 100-104 dB, each group consists of ten. During 12 days, the control group was not treatment, except 1 of mice control group was injected with tyroxine hormone for positive control. In the same time the treatment group was inducted was 12 days and 8 haours per day. The nutrition with BRI was given 15-20 g and fresh water 15-30 ml during this treatment. The temperature, humidity and body weigth also measured at this treatmen everyday. In the last day of the treatment induction was ended. The 12th day, the blood was taken for measuring tyroxine hormone and thyroid stimulating hormone. Lastly, the thyroid gland was taken out for the slice of microscopies smear.
The results of this study showed that the high intensity of noise increased the activity of the female mice (Mus musculus) thyroid gland. As the shown by increasing of tyroxine hormone, decrease of TSH and low of ratio diameter folicullli and high foliculli epitelium cell for induction 90-94 dB group and 100-104 group. Beside the rate of increasing body weight treatment groups were decreased in comparison for control group.

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
