Hormonell prevensjon for menn – UiT-studenters holdninger. En spørreundersøkelse
Get PDFMens menn teknisk sett kan gjøre kvinner gravide 365 dager i året, kan kvinner kun bære fram barn én gang i løpet av et år. Likevel har det blitt sånn at de aller fleste prevensjonspreparater er utviklet for kvinner. Menn kan per i dag kun velge mellom kondom, som relativt ofte svikter, og sterilisering, som er invasivt og med usikker reversibilitet. Det forskes på hormonell prevensjon for menn, og resultatene er lovende. Formålet med denne oppgaven var å utforske UiT-studenters holdninger til hormonell prevensjon for menn gjennom en anonym spørreundersøkelse. Resultatene viste blant annet at nesten alle syntes prevensjonsansvaret bør deles likt mellom kvinner og menn (92%), men nesten alle trodde også at kvinnen tar mest ansvar i praksis (89,7%). Flere kvinner enn menn mente at ansvaret for prevensjon faller for mye på kvinner. Menn hadde større tillit til kvinners korrekte prevensjonsbruk en motsatt. Nesten alle studentene var interessert i et nytt prevensjonsalternativ for menn (90,5%), kvinnene noe mer enn mennene. Holdninger om hvilket kjønn som ideelt sett har ansvar for prevensjon, påvirket både interesse for hormonell prevensjon for menn og menns villighet til å prøve det dersom det var tilgjengelig. Mange kvinner tynges av ansvarsfølelse og opplever et forventningspress til å bruke prevensjon. Mange menn ønsker større mulighet til å styre egen fruktbarhet. Det å ha flere enkle, trygge og effektive måter å unngå utilsiktet graviditet, er noe mange kan ha nytte av, uavhengig av kjønn. Det bør gjøres flere store kliniske utprøvinger slik at hormonell prevensjon for menn kan bli en realitet
Is it Possible to Cure Diabetes Mellitus by Herbal Treatment in Twenty First Century
Get PDFThe diabetes is the third leading cause of death in the world. The diabetic population is increasing day by day.The report of WHO shows that the diabetic population was 60 millions in 1980, 118 millions in 1995 and there will be 220 millions in 2010. Therefore, it is very important to focus on the research to find the cure to such disease, which is not only killing the lives and deteriorating the health but also, a huge social and economical burden to the nation.
Although some people prefer to say that diabetes is a Westem disease, there is already description of diabetes in the oriental literature claimed as 3500 years old. It is one of the oldest known human diseases. So far known, there are more than 1200 hypoglycemic plants already reported and many of them are used for the treatment of diabetes in several countries. None of the phytomedicines, so far reported, sufficiently meets the criteria for a medicine such as safety, efficacy, mode of action, bioavialibity, dosage, carrier system etc. to be used clinically.
There are several scientific evidences for the cause of diabetes mellitus and one major cause is the gradual destruction of insulin-producing {3 -cells in the pancreas. On this regard,the role of GAD”65, IRS, Thl andτ'h2 cells activities, and reactive oxygen spices (ROS) including SOD-activity, have been studied. Vitamin C, vitamin E, nicotinamide, lipoic acid, N-acetyl-L-cysteine are some of the substances showing the preventive action on diabetes. However, there is no systematic study on the role of natural medicines and their actions in preventing diabetes.
The main challenge for the natural medicines in 21'1 century is the systematic study. In the present review, an attempt was made to focus on the medicinal plants which are used as a traditional medicine in more than two countries. Moreover, only a few of them are taken to clinical trails. The total literature survey suggests that the use of hypoglycemic plant remedies clinically requires further systematic study.Article和漢薬研究所年報, 第27巻, 2001.04.20, Page 16-2
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
