Estructura y biodiversidad florística en cuatro parcelas del Arboretum "El Huayo", CIEFOR - Puerto Almendras, Iquitos - Perú, 2014
Get PDFEl estudio se realizó en el arboretum “El huayo” del CIEFOR, Puerto Almendras -
UNAP, distrito de San Juan Bautista, provincia de Maynas, región Loreto. El objetivo fue
obtener información, caracterizar y comparar la estructura y biodiversidad florística en
cuatro parcelas permanentes de muestreo (9, 10, 15, y 16) de 1,2 ha cada una. El
método utilizado fue la instalación de parcelas permanentes de muestreo (PPM) de 100
m x 120 m, dividida en sub parcelas de 10 m x 10 m, donde se identificaron, registraron
y midieron todos los individuos ≥ a 5 cm de DAP medidos a 1,30 m desde la base del
suelo. En el inventario forestal se registraron 4964 árboles pertenecientes a 521
especies, 173 géneros y 53 familias. El bosque de estudio presentó tres estratos: el
sotobosque con alturas ≤ 10 m; el dosel intermedio que incluyó árboles entre 10 y 20 m
de altura, y el dosel superior con árboles de más de 20 m de altura. 10 especies fueron
las más importantes por su contribución al IVI, Eschweilera grandiflora con 14,59 % ha
ocupado el primer lugar; 124 fueron comunes a las cuatro parcelas y 148 se registraron
en solo una de ellas. Las parcelas P10 y P16, a pesar de que compartieron el menor
número de especies, fueron las de mayor similitud en composición. En cambio las
parcelas P15 y P16 que compartieron más especies entre sí tuvieron una similitud
intermedia mientras que P9 y P10 presentaron la similitud más baja.Tesi

ABSTRACT
Work performance, apparently an obvious fact, but the study to consider its certainty or approximation or correlation not only had to assess numerically, but qualitatively, for this it is necessary to appreciate other factors. factors such as: psychosocial factors, psychosocial risks, perception of health, work performance and the context of a pandemic. In this regard, in the latter case, the important thing is to appreciate how the worker approached this critical moment for humanity and how it affected him, after carrying out the After the study and the data were collected, the information was expressed in detail, not using conventional instruments, but based on them or elaborated by our own consideration and accepted by experts, determining not only the relationship, but the conditions of each aspect involved in the study to summary mode. The importance of the study has been precisely to determine the conditions of psychosocial factors, psychosocial risk, perception of health and job performance and with this information, not only to appreciate which psychosocial factors affect or favor job performance, the factors corroborated by psychosocial risks that were evaluated by the same company, in addition to identifying the physical and psychological state of health of the person, all this has allowed the information obtained not only to establish the problem, but also to be able to appreciate which solutions or facts are urgently needed to improve.

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
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
