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
Comparison of the Use of Hypnotic in Psychiatric Patients with Insomnia at the Mental Health Centre Prolet in Skopje
Get PDFBACKGROUND: Insomnia is a symptom complex that comprises difficulties falling asleep, staying asleep or non-refreshing sleep in combination with daytime dysfunction or distress. Most people experience insomnia at some time during their lives. Because of its high incidence, and also because its symptoms are usually mild and transient, the importance of insomnia is frequently underestimated. Various conditions are associated with insomnia and can contribute to its development. They can be related to neurological or psychiatric disorders, which in turn may be aggravated by a deficiency of restorative sleep and daytime fatigue.
AIM: In this study, the authors compare the hypnotically effect of Flurazepam and Zolpidem applied on psychiatric cases treated in the Mental Health Centre “Prolet†in Skopje, Republic of Macedonia.
METHODS: The investigation covers 45 patients who have insomnia, in addition to their primary mental illness. Тhe examination took six weeks, and it was divided into 3 equal phases. In the first phase of three weeks, Zolpidem was used, and in the third phases, Flurazepam was administrated. We used a self-estimating scale of 13 items and methods of global clinical estimation in the evaluation of received effects.
RESULTS: The results show that referring to the induction of the sleeping period, its duration and quality and the number of awakenings, there are no significant differences between the two medicaments used, but there was a significant difference between hypnotic medicaments and placebo.
CONCLUSION: The termination with the therapy, didn`t lead to the appearance of abstinential symptoms
Синдром на “MORNING GLORY”- Приказ на случај
No full textMorning Glory Syndrome (MGS) is an uncommon congenital anomaly of the eye nerve (optic nerve) that resembles a flower known as morning glory, impairs vision, and may be associated with both ocular and non-ocular abnormalities. It has a characteristic fundoscopic appearance consisting of a large funnel-shaped cavity on the optical disc. We register an unusual congenital anomaly of the optic disc in a three-year-old female child.Синдромот на “Morning Glory” (MGS -Morning Glory Syndrom) е невообичаена конгенитална аномалија на oптичкиот нерв кој наликува на цвет познат како „morning glory“, го нарушува видот и може да бидe поврзан и со окуларни и неокуларни абнормалности. Има карактеристичен фундоскопски изглед кој се состои од големa празнина во форма на инка на оптичкиот диск. Во овој труд презентираме невообичаена вродена аномалија на оптичкиот диск кај три годишно дете од женскиот пол
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
Анализа на мајчинските и акушерските фактори за ризик за прематурна ретинопатија кај прематуруси чија тежина е над 1500г и гестациска возраст над 30 недели
Get PDFRetinopathy of Prematurity (ROP) is a major cause of preventable blindness in preterm infants. The incidence of ROP is increasing in developing countries due to increased survival of preterm infants. Retinopathy of prematurity (ROP) is a serious complication of prematurity and can lead to blindness unless is recognized and treated early. The aim of our study was to study maternal and obstetric risk factors for ROP. Material and methods: The research was an analytical "Case control" study in the period 2015-2016. The study included 163 premature babies that not meet the criteria of the American Academy of Ophthalmology (AAO), with BW more than 1500 g and gestational age more than 30 GW. Mothers were divided into two groups according the newborns with ROP and without. In order to achieve the goals, a two-part survey questionnaire was used, the first part of the questionnaire refers to questions for the mother. Results: In Vitro Fertilization increases the chance of ROP two times OR=2.1256 (1.1133-4.0585). As independent factors, multiple pregnancies increase the chance of ROP for fourth times OR = 4.0721 (2.3899-9.2511). Preeclampsia acts protective, reduces the chance of occurrence of ROP OR = 0.2147 (0.0706-0.6526). The way of delivery, the number of pregnancies, number of births, alcohol consumption, smoking, narcotics, did not present as risk factors. Conclusions: We should pay attention to the definition of risk factors, their complexity, the development and progression of retinopathy prematurnata and its prevention, because they are just one of the issues facing ophthalmologists and neonatologists throughout his work. The study confirmed the same risk factors that are registered on neonatal premathuruses according to AАО (birth weight below 1500 g and under the 30th gestation week). Conclusion: Based on the analysis of the study, a conclusion and recommendation protocols criteria to screen for ROP to modify, despite inclusion criteria of AAО to include premature neonates in screening for ROP according to the recommendation of neonatologists to increased risk of premature retinopathy, with birth weight over 1500 g and over 30 gestation weeks.Прематурната ретинопатија (РОП) е главна причина за слепило кај предвремено родените бебиња. Инциденцата на РОП се зголемува во земјите во развој и се должи на зголемување на преживување на предвремено родените деца. Прематурната ретинопaтија (РОП) е сериозна компликација кај предвремено родени деца која може да доведе до слепило, освен ако се дијагностицира и се третира рано. Цел на оваа студија е да се проучат мајчините и акушерските фактори на ризик за РОП. Материјал и методи: Истражувањето преставува аналитичка “Case control” студија во периодот 2015-2016г. Во студијата се вклучени 163 предвреме родени деца кои не ги исполнуваат критериумите на Американската академија за офталмологија (ААО), со родилна тежина се над 1500 г и гестациска старост над 30 недела. Мајките се поделени во две групи во однос на новородените со РОП и без. За оставрување на целите се користеше дводелен анкетен прашалник, првиот дел од прашалникот се однесува на прашања за мајката. Резултати: ИВФ (ин витро фертилизациа) ја зголемува веројатноста за РОП повеќе од два пати OR=2.1256 (1.1133-4.0585). Како независни фактори мултипната бременост ја зголемува веројатноста за РОП за два и пол пати. Прееклампсијата делува протективно, ја намалува веројатноста за настанување на РОП. Начинот на породување, возраста на мајката, број на бремености, број на раѓања, консумирање на алкохол, пушење, наркотици не претставувaат ризик фактори. Треба да се обрне големо внимание на дефинирањето на ризик факторите, нивната комплексност, развојот и прогресијата на прематурната ретинопатија и нејзината превенција кои се само еден дел од прашањата со кој се соочуваат офталмолозите и неонатолозитe во текот на својата работа. Во студијата се потврдија истите ризик факори кои се регистрираат на кај прематурусите според ААО (родилна тежина под 1500 г и под 30-та гестациска недела). Заклучок: протоколите за скрининг на РОП да се модифицираат, покрај инклузионите критериуми на ААО да се вклучат и прематуруси според препораката на неонатолозите за зголемен ризик за развој на прематурна ретинопатија, а се со родилна тежина над 1500 г и над 30-та гестациска недела
