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
Hongos asociados con la enfermedad "miada de perro" en el cultivo de chile
Get PDFThe chili pepper (Capsicum annuum L.) is vulnerable to a disease known in the state of Zacatecas as "dog's urine", which appeared recently and its importance increases every day, since it reduces the production of the pepper. Some of the symptoms are the necrosis of leaves and seeds, which leads to considering the presence of fungi. The aim of this study was to know the phytopathogenic fungi that were related to the diseased plants in June and July, from 2004 to 2006. Leaves, stems and seeds of healthy and diseased plants were gathered in commercial plantations in Fresnillo, Calera, Villa de Cos, Villa García and Pánfilo Natera, in the state of Zacatecas, they were transferred to petri dishes viapimaricin-ampicilin-rifampin-PCNB and hymexazol (PARPH), potato dextrose agar (PDA) and water-agar culture media. The organisms that grew on leaves, stems and seeds were identifiedusing taxonomical codes. The fungi found were Alternaria solani (21% in healthy plants and 41% in diseased plants), Fusarium roseum (10.2% in healthy plants and 16.1% in diseased plants), Phytophthora capsici (0.6% in healthy plants and 3.7% in diseased plants), Nigrospora spp. (0.7% and 1.7%), Aspergillus spp. (0.6%y 1.7%) and Penicillium spp. (0.2% and 0.1%), respectively, as well as saprophytic bacteria (2.5% in diseased plants). In seeds from diseased plants, there was no fungal growth found 43.2% of the plantations sampled and in healthy seeds there were saprophytic fungi (in 20%), Alternaria solani (13.5%), Aspergillus spp. (20%) and Fusarium spp. (3.3%). Based on the symptoms these pathogens cause on vulnerable plants, they were assumed to be related to the disease "dog's urine", but they do not participate directly in the production of the symptoms.El chile (Capsicum annuum L.) es afectado por una enfermedad que en Zacatecas se conoce como "miada de perro"�; es de aparición reciente y su importancia cada día es mayor debido que reduce la producción de fruto. Algunos de los síntomas son la necrosis en hojas y semillas, que hace pensar en la presencia de hongos. El objetivo de esta investigación fue conocer los hongos fitopatógenos que se encuentran asociados con plantas enfermas de junio y julio 2004 a 2006. Se colectaron hojas, tallos y semillas de plantas sanas y con síntomas de la enfermedad en siembras comerciales de Fresnillo, Calera, Villa de Cos, Villa García y Pánfilo Natera, en el estado de Zacatecas; se transfirieron a caja petri con medio de cultivo pimaricina-ampicilinarifampicina- PCNB e himexazol (PARPH), papa dextrosa agar (PDA) y agua-agar. Los organismos que se desarrollaron en hojas, ramas y semillas, se identificaron utilizando claves taxonómicas. Se encontraron los hongos Alternaria solani (21% en plantas sanas y 41% en plantas enfermas), Fusarium roseum (10.2% en plantas sanas y 16.1% en plantas enfermas), Phytophthora capsici (0.6% en plantas sanas y 3.7% en plantas enfermas), Nigrospora spp. (0.7% y 1.7%), Aspergillus spp. (0.6% y 1.7%) y Penicillium spp. (0.2% y 0.1%), respectivamente; así como bacterias saprófitas (2.5% en plantas enfermas). En semillas provenientes de plantas enfermas no se obtuvieron crecimientos fungosos 43.2% de las siembras muestreadas y en semilla sana se encontraron: hongos saprófitos 20% de ellas, Alternaria solani en 13.5%, Aspergillus spp. 20% y Fusarium spp. 3.3%. Con base en los síntomas que estos patógenos ocasionan en plantas susceptibles, se consideró que se encuentran asociados con la enfermedad "miada de perro"�, pero no participan directamente en la producción de los síntomas
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
miR-4780 Derived from N2-Like Neutrophil Exosome Aggravates Epithelial-Mesenchymal Transition and Angiogenesis in Colorectal Cancer
No full textDespite significant advances in diagnostic methods and treatment strategies, the prognosis for patients with advanced colon cancer remains poor, and mortality rates are often high due to metastasis. Increasing evidence showed that it is of significant importance to investigate how the tumor microenvironment participates in the development of colorectal cancer (CRC). In this manuscript, neutrophils were sequentially stimulated with all-trans retinoic acid and transforming growth factor-β in turn to induce the neutrophil polarization. Differentially expressed miRNA in neutrophil exosomes have been sequenced by microarray profile, and the effect of N2-like neutrophil-derived exosomal miR-4780 on epithelial-mesenchymal transition (EMT) and angiogenesis was investigated. In our results, we found that neutrophils were enriched in CRC tumor tissue and that CD11b expression correlated with tumor site and serous membrane invasion. At the same time, we demonstrated that internalization of N2 exosomes exacerbated the viability, migration, and invasion of CRC cell lines and inhibited apoptosis. To further investigate the molecular mechanism, we analyzed the miRNA expression profile in the N2-like neutrophils, which led to the selection of hsa-miR-4780 for the subsequent experiment. The overexpression of miR-4780 from N2-like neutrophil-derived exosomes exacerbated EMT and angiogenesis. Moreover, miR-4780 can regulate its target gene SOX11 to effect EMT and angiogenesis in CRC cell lines. CRC with liver metastasis model also validated that aberrant expression of miR-4780 in N2-like neutrophil exosomes exacerbated tumor metastasis and development of tumor via EMT and angiogenesis. In conclusion, our current findings reveal an important mechanism by which mR-4780 from N2-like neutrophil exosomes exacerbates tumor metastasis and progression via EMT and angiogenesis
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
