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
Evaluation of meningiom cases operated at neurosurgery clinic of Afyonkarahisar HEALTH Sciences University Faculty of Medicine: A retrospective study
No full textAmaç: Bu çalışmanın amacı; astrositom tanısı ile hastanemize başvuran ve opere edilmiş olan olguların; retrospektif olarak, yaş, cinsiyet, etyolojik özellikler, başvuru şikayetleri, patolojik sınıflama, postoperatif takibi, survey ve mortalitelerini içeren sonuçlarımızı literatürdeki mevcut sonuçlar ile karşılaştırmak ve tartışmaktır. Materyal-Metod: Bu çalışmaya Afyonkarahisar Sağlık Bilimleri Üniversitesi Tıp Fakültesi Beyin ve Sinir Cerrahisi Kliniğinde 1 Ocak 2013 ile 31 Aralık 2021 tarihleri arasında astrositom tanısıyla başvuran ve opere edilen 65 hasta dahil edilmiştir. Hastaların hastaneye başvurduklarında çekilen Bilgisayarlı Tomografi (BT) ve Magnetik Rezonans Görüntüleme (MRG) ve operasyon sırasında alınan patoloji örnekleri sonucunda her bir hastanın preop ve postop durumu incelenmiştir. Yapılan incelemeler neticesinde elde edilen sonuçlar istatiksel olarak değerlendirilmiştir. Bulgular: Hastaların 53 (%80,3)'nün tanısı glioblastoma idi. 65 hastanın tamamı sınıflandırıldığında; Grade I'de 4 (%6,2), Grade II'de 3 (%4,6), Grade III'de 3 (%4,6), Grade IV'te 55 (%84,62) hasta mevcut idi. Postoperatif süreçte 12 (%18,5) hastaya sadece radyoterapi, 9 (%13,84) hastaya sadece kemoterapi, 40 (%61,5) hastaya kemoterapi ve radyoterapi tedavisi birlikte uygulandı. Tanıları bakımından karşılaştırıldığında Glioblastom tanılı hastalarda mortalite diğer tanılara göre istatiksel açıdan daha yüksekti (p<0,001). Sonuç: Çalışma sonucunda tek başına radyoterapi veya kemoterapi kullanan hastalar ile mortalite arasında istatiksel olarak anlamlı bir fark bulunmadı. Daha geniş hasta popülasyonu ile yapılacak çalışmalara ihtiyaç vardır. Anahtar Kelimeler: Astrositom, Glioblastoma Multiforme, Izositrat dehidrogenazObjective: Astrocytes are the defense cells of the central nervous system. Different morphological types and anaplastic types of astrocytomas can coexist. Astrocytomas arise from astrocytes. Gliablostoma multiforme is the most common astrocytic tumor in the adult age group and has a high mortality rate. Of the cases who applied to our hospital with the diagnosis of astrocytoma and were operated; Aim of this study is to compare and discuss the results, including age, gender, etiological features, admission complaints, pathological classification, postoperative follow-up, surveillance and mortality, retrospectively with the current results in the literature. Materials and Methods: This study included 65 patients who were admitted to Afyonkarahisar Health Sciences University, Faculty of Medicine, Department of Neurosurgery, between January 1, 2013 and December 31, 2021 with the diagnosis of astrocytoma and operated. As a result of the Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) taken when the patients were admitted to the hospital and the pathology samples taken during the operation, the preoperative and postoperative status of each patient was examined. The results obtained as a result of the examinations were evaluated statistically. Results: The diagnosis of 53 (80.3%) patients was glioblastoma. When all 65 patients were classified; There were 4 (6.2%) Grade I, 3 (4.6%) Grade II, 3 (4.6%) Grade III, 55 (84.62%) Grade IV patients. In the postoperative period, only radiotherapy was applied to 12 (18.5%) patients, chemotherapy alone to 9 (13.84%) patients, and chemotherapy and radiotherapy treatment to 40 (61.5%) patients. When compared in terms of their diagnoses, mortality was statistically higher in patients with glioblastoma compared to other diagnoses (p<0.001). Conclusion: As a result of the study, no statistically significant difference was found between mortality and the patients who used radiotherapy or chemotherapy alone. Further studies with a larger patient population are needed. Keywords: Astrocytoma, Glioblastoma Multiforme, Isocitrate Dehydrogenas
The Expectance of Patients From Nursing and Current Practice in Neurosurgery Clinic
No full textHasta memnuniyeti, sağlık hizmetlerinin bir sonucu ve genellikle bakım kalitesinin
bir göstergesi olarak kabul edilmektedir. Aynı zamanda, hemşirelik bakımının
değerlendirilmesi ve kalitenin belirlenmesinde bir geri bildirim sağlamaktadır. Hasta beklentilerinin karşılanması hasta memnuniyetinin sağlanmasında önemli bir
etkendir. Çalışmamızda nöroşirürji kliniğinde yatan hastaların hemşirelik bakımına
ilişkin beklentileri ve karşılanma durumu sorgulanarak hastaların hemşirelik bakım
hizmetlerine dair düşünceleri hakkında bilgi edinilmesi ve bu bilgiler ışığında
hemşirelik bakımının kalitesinin geliştirilmesi amaçlandı.
Araştırma, Afyon Kocatepe Üniversitesi Ahmet Necdet Sezer Araştırma ve
Uygulama Hastanesi’nde, Ocak 2008-Eylül 2008 tarihleri arasında, Nöroşirürji
Kliniği’nde yatarak tedavi gören 90 hasta üzerinde gerçekleştirildi. Verilerin elde
edilmesinde; Kişisel Bilgi Formu ile birlikte Newcastle Hemşirelik Bakımından
Memnuniyet Ölçeği ve Hemşirelik Bakımına İlişkin Beklentiler ve Karşılanma
Durumu Soru Formu kullanıldı. Verilerin değerlendirmesinde; yüzdelik dağılımlar,
one way ANOVA, t- testi, ki-kare testi uygulandı.
Yaptığımız çalışmada hastaların %41,1’inin 40-59 yaş grubunda, %66,7’sinin
kadın, %86,7’sinin evli, %53,3’ünün ilkokul mezunu oldukları, %63,3’ünün ev
hanımı ve %98,9’unun bir sosyal güvencesinin olduğu belirlendi. Ayrıca hastaların
%85,6’sının daha önce hastane deneyiminin olduğu, %81,1’inin kendi isteği ile
hastaneye başvurmuş olup yatışının yapıldığı ve %71,1’inin 1-10 gün arasında
hastanede yatmakta olduğu saptandı. Hastaların büyük bir kısmının aldıkları
hemşirelik bakımından memnun ya da çok memnun olduğu, genel memnuniyet
düzeyinin 73,32±13,42 olduğu belirlendi. En yüksek 3,91±0.80 memnuniyet
ortalaması “hemşirelerin mahremiyetinize gösterdikleri saygıdan”, olmasına karşın
en düşük memnuniyet ortalaması 3,39±1,08 ile “hemşirelerin size durumunuz ve
tedavinizle ilgili yeterli bilgi vermelerinden” olduğu saptandı. Hastaların yaşı,
cinsiyeti, eğitim durumu, mesleği, medeni durumu, sosyal güvence durumu, daha
önceki hastane deneyimi, hastaneye yatış şekli ve yatış süresinin hemşirelik
bakımından memnuniyetlerini etkilemediği saptandı. Hastaların hemşirelerden
beklentilerini ve karşılanma durumların sorguladığımız bölümde genel olarak
hastaların hasta kabulüne ve tedaviye ilişkin beklentileri yüksek iken günlük yaşam
aktiviteleri ve ziyaretlerle ilgili beklentileri daha düşük bulundu
Sonuç olarak; nöroşirürji kliniğinde yatan hastaların aldıkları hemşirelik
bakımından genel olarak memnun oldukları ancak hastaların kliniklere kabulü, tetkik
ve tedaviler , hastalığın gidişatı konularında hastaların daha fazla bilgilendirilmesi ve hastalarla daha fazla iletişim kurulması gerektiği saptandı. Memnuniyet düzeyini
artırmak amacıyla hemşirelere hasta memnuniyeti ve hasta memnuniyetini etkileyen
faktörler hakkında hizmet içi eğitim verilmesi önerilebilir.Patient satisfaction is accepted as the result of service and an indicator about quality
of service. At the same time patient satisfaction analyses are reliable data to evaluate
the nursing care and to define the quality of care. Level to be met of patients
expectations is an important indicator for patient satisfaction. In our study we aimed
both to get knowledge thoughts of patients about nursing care by questioning
expectations of inpatients in neurosurgery clinic and to develop the quality of nursing
care.
The research carried out on 90 inpatient in Neurosurgery Clinic of Afyon
Kocatepe University Ahmet Necdet Sezer Research Hospital between Jauary 2008
and December 2008. To analyse the data we used Form of Personal Information,
Newcastle Satisfaction with Nursing Care Scale, and The Expectation From Nursing
Care and Current Practices Questionaire. The data analysed by persentage
distrubition, one way ANOVA test, t test, and ki-kare test.
In the study, %41,1 of patients were 40-59 years, %66,7 were female, %86,7
were married, %53,3 had graduated from primary school, %63,3 were housewives
and %98,9 of patients had health insurance. Also %85,6 of patients were hospitalized
in past, %81,1 of patients applied by themselves and hospitalized, %71,1 of them
stayed for 1-10 days in clinic. In the study the level of patients’ satisfaction with
nursing care during their recent hospital stay are investigated. Most of patients were
rated their satisfaction “quite satisfied” and “very satisfied”. In generally the level of
satisfaction score was 73,32±13,42. The highest score about mean of satisfaction
level was 3,91±0,80 “the amount of privacy nurses gave you”, and the lowest score
was 3,39±1,08 “the amount of information nurses gave to you about your condition
and treatment”. And patients ages, gender, educational status, professional status,
marital status, previous hospital experiences, staying mode and staying period were
not efficient on patient satisfaction with nursing care. In the chapter, patient
expectations with nursing care and to be met of patient expectations are
questionaried, its defined that although the patiens have high level expectations about
patient acception and cure, they have lover level expectations about usual living
activities and patient visits.
Consequently, its determined that; the inpatients are generally satisfied with
nursing care but they had to be more informed about acception procedure, analyses and treatment and the condition of disease. The patients also expects more
comminication activities with neurosurgery services. In order to get satisfaction level
higher, training courses can be given about patient satisfaction and about effective
factors on patient satisfaction, to the nurses
The effect of triamsinolone asetonid and clioquinol to prevent epidural fibrosis on the after experimental laminectomi
No full textBel ağrısı en sık görülen sağlık problemlerindendir. Lomber disk hernisi bel ağrısının en sık sebebidir. Lomber disk hastalığında cerrahi tedavi sonrası yaklaşık %15 olguda ``Başarısız Bel Cerrahisi Sendromu'' (BBCS) gelişmektedir (13,14). Lomber disk hernisi cerrahisinin başarısızlığına neden olan en önemli sebeplerden biri de epidural fibrozistir.Çalışmada Triamsinolon Asetonid ve Clipquinol'ün, ratlarda deneysel olarak oluşturulan laminektomi modelinde, epidural fibrozisin önlenmesindeki etkileri araştırıldı.Çalışmada 7 farklı grupta toplam 46 adet winstar cinsi erkek rat kullanıldı. Deneklere ketamin ve xylazin anestezisi altında L3 ve L4 total laminektomi yapıldı. Sham grubundaki deneklere herhangi bir cerrahi işlem ve ilaç yapılmadı. Kontrol grubunda sahaya serum fizyolojik uygulandı. Üçüncü gruba intra operatif epidural triamsinolon asetonid 10 mg/kg dozda uygulandı. Dördüncü gruba intra operatif epidural clioquinol 20 mg/kg dozda uygulandı. Beşinci gruba intra operatif epidural triamsinolon asetonid 10 mg/kg dozda ve clioquinol 10 mg/kg dozda uygulandı. Altıncı gruba intra operatif epidural triamsinolon asetonid 10 mg/kg dozda ve clioquinol 20 mg/kg dozda uygulandı. Yedinci gruba ise intra operatif epidural triamsinolon asetonid 10 mg/kg dozda ve clioquinol 40 mg/kg dozda uygulandı. Denekler 6. haftanın sonunda ölümcül dozda intraperitoneal sodyum pentotal ile sakrifiye edildiler.Sakrifiye edilen deneklerden hazırlanan patoloji preparatları hemotoksilen eozin ve Masson trikrom ile boyandı. Örneklemeler ışık mikroskopunda yabancı cisim reaksiyonu, inflamatuar hücre yoğunluğu, fibroblast yoğunluğu ve skar oluşumu açısından değerlendirilerek semikantitatif skala ile skorlandı. Çıkan sonuçlara göre, Triamsinolon asetonid 10 mg/kg dozda deneysel laminektomi sonrası oluşan epidural fibrozisi önleyememiştir. Diğer taraftan Clinoquinol (20 mg/kg) deneysel laminektomi sonrası oluşan epidural fibrozisi anlamlı bir şekilde azaltmıştır. Laminektomi sonrası oluşan epidural fibrozisin önlenmesinde, Clinoquinol'ün kullanılabileceğini düşünüyoruz.Lumbar pain is one of the most frequently seen health problems. Lumbar disc hernia is the most common cause of lumbar pain. In lumbar pain disease, ?Unsuccesfull Lumbar Surgery Syndrome? (ULSS) is seen on about 15% of patients (13, 14). One of the most important factor causing failure of Lumbar disc hernia surgery is epidural fibrosis.In our study, investigated the effects of Triamcinolone Acetonid and Clioquinol for prevention of seen epidural fibrosis after experimental laminectomy on rats.Total 46 winstar race male rats in 7 groups were used in the study. L3 and L4 total laminectomy were appiled to rats under anesthesy of ketamine and xylazin. Any surgical procedure or medical treatment was not given to the rats in Sham group. In the control group, normal saline was applied to the area. Intra operative epidural triamcinolone acetonid 10 mg/kg was applied to third group. Intra operative epidural Clioquinol 20 mg/kg was applied to fourth group. Intra operative epidural triamcinolone acetonid 10 mg/kg and Clioquinol 10 mg/kg were applied to fifth group. Intra operative epidural triamcinolone acetonid 10 mg/kg and Clioquinol 20 mg/kg were applied to sixth group. Finally, Intra operative epidural triamcinolone acetonid 10 mg/kg and Clioquinol 40 mg/kg were applied to seventh group. Subjects sacrified using sodium pentotal at lethal dose at the end of the sixth week.Pathology samples prepared from sacrified subjects were painted with hemotoxilen eozine and Mason tricrome. Samples were evaulted for foreign substance reaction, inflamatory cell density, fibroblast cell density and scar forming under light microscope, and scored by using semicantitative scale. According to result, Triamsinolon asetonid (10mg/kg) coluld not prevent epidural fibrosis after experimental laminectomy. On the other hand, Clioquinol 20 mg/kg significantly decreased epidural fibrosis after experimental laminectomy. We think that Clioquinol maybe used to prevent of epidural fibrosis occurred after laminectomy
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
