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
Highly stable two-level current fluctuation in complex oxide heterostructures
No full textTwo-level systems based on point defects in dielectric oxides offer promising entropy source for random number generators. The random telegraph noise (RTN) generated by the two-level systems is ideal for creating random bit-strings for advanced computing and cryptographic technologies. However, in classical oxide systems, RTN signals often suffer from instability due to undesired defect migration and metastable electronic states. Herein, we present a two-level quantum system based on SrRuO3/LaAlO3/Nb-doped SrTiO3 heterostructure, which incorporates two different types of point defects, oxygen vacancies and antisite Ti defects. Temporal electron localization at antisite defects alters the energy levels of nearby oxygen vacancies through instantaneous Coulomb interaction, resulting in two-level current fluctuation across the interface. The RTN-like current signals exhibit high stability at room temperature. We utilize the stable two-level fluctuations to generate random bit-strings and confirm their applicability in practical stochastic machine learning algorithms for image super-resolution. This study provides a guideline for designing reliable entropy sources by exploiting the complementary interactions between cation and anion point defects in oxide-based electronic systems, essential for hardware-based random number generators.
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
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

,[vi, 115p :]자유무역의 모순점을 해결하기 위해 나타난 개념인 공정무역은 개발도상국 생산자에게 공정한 임금을 제공하여 빈곤문제를 해결하려는 국제적 시민운동으로 1960년부터 꾸준히 그 규모가 증가하고 있다. 공정무역에 대한 학문적 연구를 살펴보면 대부분이 디자인적 관점이 아닌 경영학적 시각에서 이루어 진 것을 볼 수 있다. 하지만 공정무역 제품도 소비자를 설득시켜 구매로 이어지게 해야 하는 ‘상품’ 의 특성을 갖고 있고, 이때, 디자인은 소비자의 구매결정 단계에서 중요한 역할을 한다. 이에 본 연구는 소비자의 구매의도를 높이는 공정무역 제품 디자인에 대해 연구를 진행하려 한다. 많은 공정무역 제품 중 디자인의 영향력이 크게 작용할 수 있는 수공예 제품으로 연구대상을 한정 하였다.
본 연구는 크게 3가지 단계로 이루어져 있다. 첫째, 현 공정무역의 구조와 디자인 요소에 대한 기존 연구의 탐색을 위해 문헌 조사를 실시 하였고, 현재 판매되고 있는 공정무역 수공예 제품들을 살펴보기 위해 사례조사와 전문가 인터뷰를 실시 하였다. 둘째, 공정무역 수공예 제품 디자인을 ‘제품 디자인 요소’와 ‘패키지 정보요소’의 두 부분으로 나누어 디자이너 워크샵과 설문을 진행하여 각각에 대한 요소의 추출 및 평가를 실시하였다. 이후, 소비자를 대상으로 구매의도 평가를 실시하였으며, 이때 공정무역 수공예 제품과 일반 수공예 제품과의 차이를 비교하기 위해 공정무역과 일반 제품으로 나누어 동시에 진행하였다. 다음으로 평가된 데이터에 대해 소비자 인터뷰와 focus group interview를 열어 정성적인 분석을 실시하였다. 셋째, 앞선 단계를 통해 도출된 인사이트를 바탕으로 소비자 구매의도를 높이는 공정무역 수공예품 디자인 가이드라인을 제품과 패키지 각각 패브릭, 악세서리, 코스메틱으로 나누어 제안하였다. 다음으로 제안한 가이드라인을 사용하여 디자이너 워크샵을 통해 사례개발을 하였고, 전문가 인터뷰로 연구의 효용성과 적용 가능성에 대해 검증하였다.
이를 통해 공정무역 수공예 제품의 경우 패브릭 제품은 실용성, 전통성, 감성이, 악세서리 제품은 심미성, 실용성, 전통성이, 코스메틱 제품은 실용성과 자연친화성이 소비자의 구매의도를 높이는데 중요한 요소로 작용하는 것을 발견 하였고, 공정무역 수공예 제품 패키지의 경우, 패브릭과 악세서리 패키지는 제작자의 이야기와 이미지가. 코스메틱 패키지는 제작 방법과 제작과정 이미지가 중요한 정보요소로 작용하는 것을 알 수 있었다. 이를 바탕으로 한 디자인 가이드 라인으로 각 카테고리 별 사례개발을 진행한 후 전문가 인터뷰를 통해 실제 적용 가능성에 대해 검증을 완료 하였다.
본 연구에서 제안한 디자인 가이드라인으로 많은 공정무역 수공예품 판매단체와 생산조합의 제품과 패키지 디자인에 도움을 줄 수 있을 것으로 나아가 개발도상국 수공예품 생산자 이윤의 확대와 공정무역 시장 확대에 도움이 될 수 있을 것으로 예상된다.한국과학기술원 :산업디자인학과
