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
진행성 상피성 난소암에서 18F-FDG PET/CT 상 발견된 횡경막 상부 임파선 전이의 예후에 대한 연구
No full text학위논문 (석사)-- 서울대학교 대학원 : 의학과, 2014. 8. 송용상.연구목적: 진행성 상피성 난소암에서 횡경막 상부 임파선 전이(supradiaphragmatic lymph node metastasis, SdLNM) 는 F-18-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) 를 통해 흔히 발견된다. SdLNM 은 PET/CT 를 통해 발견되는 원위 전이 중 가장 흔하며 이로 인하여 병기가 3기에서 4기로 변경된다. 진행성 상피성 난소암에서 PET/CT 상 발견된 SdLNM 의 예후에 대한 연구는 보고된 바가 없기에 의무기록을 이용한 후향적 연구를 진행하였다.
연구방법: 2003년부터 2010년까지 병기 III기 또는 IV 기의 진행성 상피성 난소암으로 진단받은 환자 중 치료 시작 전 PET/CT 를 촬영하였으며 생존분석이 가능한 환자 75명의 의무 기록을 검토하였다. PET/CT 결과를 토대로 병기설정을 하였을 때 PET 병기 3기는 45명 (그룹 1), PET 병기 4기는 30명이었다. PET 병기 4기 환자 중 SdLNM 만으로 병기 IV 로 분류된 환자는 22명 (그룹 2) 이었고 SdLNM 과 다른 원위 전이가 동반된 환자는 8명 (그룹 3) 이었다. 세 그룹의 무병 생존과 전체 생존을 비교 분석하였다.
결과: 연구 대상 환자의 나이의 중앙값은 50세 이었으며 경과 관찰 기간의 중앙값은 46.6 개월이었다. 53명은 일차 종양 감출술을 시행 후 보조항암치료를 시행하였으며 22명은 평균 3회의 선행 항암치료를 시행 후 종양 감축술과 보조항암치료를 시행하였다. 그룹 1과 비교하였을 때 그룹 2 의 무병 생존과 전체 생존은 차이가 없었다. 하지만 그룹 3 은 그룹 1 과 그룹 2 에 비하여 전체 생존이 짧았다. 나이, 조직학적 유형, 분화도, 선행 항암치료 여부, 수술 후 잔여 종양 크기 등을 보정한 콕스 회귀 분석을 시행하였다. SdLNM 과 다른 원위 전이가 동반되었을 경우 전체 생존과 무병 생존에 있어 독립적인 예후 인자이었으나 SdLNM 단독은 예후에 유의한 영향을 갖지 않았다.
결론: 다른 원위 전이 동반 없이 SdLNM 이 단독으로 존재하는 병기 4기 환자는 병기 3기 환자에 비해 나쁜 예후를 보이지 않았다. PET/CT 로 발견된 원위 전이는 그 분포에 따라 다른 예후를 보이므로 PET/CT 로 발견된 SdLNM 자체를 나쁜 예후 인자로 간주하는 것은 피해야 한다.Introduction: In various study, supradiaphragmatic lymph node metastasis (SdLNM) was found to be the most common findings to classify FIGO stage III and IV disease in radiologic staging by PET/CT. Consequently, it is apparent that the use of PET/CT for diagnosing epithelial ovarian cancer (EOC) causes stage migration from stage III to stage IV and majority of the newly detected distant metastatic lesion is SdLNM. However, the prognostic impact of SdLNM detected by PET/CT has not been studied separately until today. Therefore I conducted retrospective study evaluating prognostic impact of SdLNM detected by PET/CT.
Methods: Seventy-five patients with advanced-stage EOC underwent PET/CT prior to treatment between 2003 and 2010. The patients were divided into three groups, as follows: PET stage III (n=45, group 1)PET stage IV by SdLNM alone (n=22, group 2)PET stage IV by SdLNM with other distant metastasis (n=8, group 3).
Results: Median age was 50 years, and the median duration of follow up was 46.6 months. Both overall survival (OS) and progression-free survival (PFS) were not poorer in group 2 than in group 1, whereas group 3 had worse OS when compared to group 1 (log rank, P =0.041) and group 2 (log rank, P <0.001). Multivariate analysis was conducted and included age, histology, grade, neoadjuvant chemotherapy and amount of intraperitoneal residual tumor. Whereas SdLNM with other distant metastasis was an independent prognostic factor for both OS (hazard ratio [HR]: 3.4, 95% confidence interval [CI]: 1.03-11.15) and PFS (HR: 3.07, 95% CI: 1.12-8.43), SdLNM alone was not associated with poor prognosis.
Conclusions: Stage IV disease caused by SdLNM alone was not associated with poor survival unless accompanied by other distant metastasis. SdLNM alone should not be regarded as a poor prognostic factor when defining stage IV in advanced-stage EOC.I. Introduction
