Departamento Académico de Manejo ForestalEl presente trabajo de suficiencia profesional tiene como objetivo presentar una propuesta de un Sistema de Gestión de Seguridad y Salud en el Trabajo para las actividades de podas en altura de árboles urbanos para siete municipios distritales de Lima. Esta propuesta de sistema comprende procedimientos y registros de trabajo seguro basados en un diagnóstico situacional de las actividades de podas en altura. Para la elaboración del diagnóstico se aplicó la metodología de observación directa de las actividades de poda en altura y se realizó una encuesta a operarios de diferentes municipios distritales de lima, basadas en la Norma Técnica Peruana 851.002-2016, Norma ANSI Z133 y la Ley de seguridad y salud en el trabajo Nº 29783. Los resultados de las encuestas mostraron que el 79.2% de los operadores desconocen las normativas de seguridad para podas en altura, el 75% usa equipos inadecuados para la poda en altura y sólo el 20.8% posee una certificación que valida la aptitud y conocimientos para realizar podas de altura en árboles. Se realizó una evaluación del desempeño y/o cumplimiento de normas legales, producto de la cual se evidenció que ninguno de las instituciones, cuenta con sistemas de gestión implementados al 100%. Habiéndose evidenciado las deficiencias en la ejecución de las actividades de poda de altura de árboles urbanos. En base a los resultados del diagnóstico se diseñó la propuesta de Sistema de Gestión de Seguridad y Salud en el Trabajo para las actividades de podas en altura de árboles urbanos y comprende procedimientos específicos que minimicen el riesgo de accidentabilidad en los operarios.The objective of this work of professional sufficiency is to present a proposal for a Management System of Safety and Health at Work for the activities of pruning at height of urban trees in seven district municipalities of Lima. This system proposal includes procedures and records of safe work based on a situational diagnosis of pruning activities at height. For the elaboration of the diagnosis, the methodology of direct observation of pruning activities at height was applied; At the same time, virtual surveys were carried out with operators from different district municipalities of Lima, based on the Peruvian Technical Standard 851.002-2016, ANSI Z133 Standard and the Occupational Health and Safety Law No. 29783. The results of surveys showed that 79.2% of the operators are unaware of the safety regulations for pruning at height, 75% use inappropriate equipment for pruning at height and only 20.8% have a certification that validates the aptitude and knowledge to perform height pruning of trees. The results of the performance evaluation and / or compliance with legal norms, showed that none of the institutions have management systems implemented 100%. Having evidenced the deficiencies in the execution of the activities of pruning the height of urban trees. The Occupational Health and Safety Management System designed for the activities of pruning at height of urban trees is based in diagnosis results and included specific procedures that minimize the risk of accident in the operators
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
Rasgos funcionales relacionados al fuego en 5 especies forestales en una formación vegetal subxerófila en la Selva Central del Perú
No full textUniversidad Nacional Agraria La Molina. Facultad de Ciencias Forestales. Departamento Académico de Manejo ForestalCada vez está más claro cómo el cambio climático afecta a la diversidad vegetal de los bosques tropicales húmedos. En consecuencia, es esencial recopilar datos ecofisiológicos sobre diversas especies arbóreas a partir de sus características funcionales. Este estudio evaluó la ramificación (IDA), la densidad básica (DB), el grosor de la corteza (Ect) y describió la anatomía de esta en cinco especies que pueden estar adaptadas al fuego: Astronium fraxinifolium, Curatella americana, Luehea paniculata, Machaerium hirtum, y Physocalymma scaberrimum. Las mediciones de los rasgos funcionales se realizaron en dos poblaciones: una que presentaba indicios de quemaduras y otra que no. Para determinar el impacto del fuego en los atributos investigados, se compararon los resultados de las dos poblaciones. Los valores de IDA, DB y Ect fueron, de media, de 2,662 m-1 , 0,461 g/cm3 y 8,636 mm en los árboles quemados y de 1,945 m-1 , 0,467 g/cm3 y 5,150 mm en los árboles no quemados. Por último, se encontró que una mayor ramificación y una corteza más gruesa pueden sugerir una especie adaptada al fuego, sin embargo, no hubo asociación estadísticamente significativa (p=0,45) entre la densidad básica de ramas y el impacto de las quemaduras en los árboles.It is becoming more and more clear how plant diversity in humid tropical forests is impacted by climate change. Consequently, it is essential to gather ecophysiological data about various tree species using their functional characteristics. This study evaluated branching (IDA), basic density (DB), bark thickness (Ect), and described bark anatomy in five species that may be adapted to fire: Astronium fraxinifolium, Curatella americana, Luehea paniculata, Machaerium hirtum, and Physocalymma scaberrimum. The study also focused on characterizing functional traits related to fire resistance in a subxerophytic vegetation of the Chanchamayo valley. Functional trait measurements were done on two populations: one that showed evidence of burns and the other that did not. To ascertain the impact of fire on the attributes under investigation, the outcomes of the two populations were compared. IDA, DB, and Ect values were, on average, 2,662 m-1, 0,461 g/cm3, and 8,636 mm in burned trees and 1,945 m-1, 0,467 g/cm3, and 5,150 mm in unburned trees. Lastly, it was found that more branching and thicker bark may suggest a fire-adapted species, however there was no statistically significant association (p=0.45) between the basic density of branches and the impact of the burns on the trees
