Gestión de personas para reducir la incertidumbre en la planificación y ejecución de un proyecto de infraestructura deportiva
Full text linkEn la actualidad, los proyectos de construcción están sometidos a una gran complejidad e incertidumbre debido a los múltiples interesados que forman parte de sus procesos. Además de ello, cada vez se enfrentan a plazos y costos más reducidos, lo que genera que muchos de ellos se enfrentes a sobrecostos y que se excedan los plazos contractuales. Ante este problema, diversas metodologías han surgido con el fin de gestionar el costo y presupuesto de los proyectos, pero dichas metodologías se enfocan más en los procesos y no en las personas, quienes son las que finalmente entregan el proyecto de construcción. Es así que la siguiente investigación propone e implementa una metodología de gestión de personas basada en la filosofía lean, que permita reducir la incertidumbre en un proyecto de infraestructura deportiva. El trabajo de tesis, se divide en cinco capítulos, como se detalla a continuación:
En el Capítulo I, se realiza una revisión de algunas propuestas para gestionar a las personas en los proyectos de construcción, se define el problema y se establecen los objetivos de la investigación.
En el Capítulo II, se realiza una revisión literaria sobre los conceptos que serán estudiados en la investigación, se desarrolla la teoría de lean Construction, base de nuestro modelo de gestión de personas, y se estudia Last Planner® System(LPS) a nivel conceptual, identificando los problemas de implementación y los beneficios del mismo, pues será implementado en nuestro modelo de gestión de personas.
En el Capítulo III, se propone el modelo de gestión de personas y se revisan cuatro modelos de gestión de personas encontrados en la revisión literaria. Además, se propone un modelo de gestión de personas que será detallado a lo largo del capítulo y se explica la teoría de gestión del cambio para la implementación del modelo. El modelo, está compuesto por tres partes, la primera que corresponde a las personas, donde se revisan conceptos de la perspectiva de la acción lingüística, la colaboración, el liderazgo y el respeto, como base conceptual del modelo. Luego pasamos a los procesos donde se propone el uso de la gestión visual y LPS, es así donde se desarrolla un manual de implementación para cada uno de los niveles de LPS. El capítulo termina con el último elemento del modelo, el cual es la tecnología y se propone el uso de BIM para el seguimiento de tareas y el uso de las tecnologías de la información para una mejor comunicación.
En el Capítulo IV, se detalla el proceso de implementación de la propuesta a lo largo de cuatro meses y se describen como evolucionan las distintas herramientas propuestas en el proyecto mes a mes, en este capítulo se muestra la implementación de la gestión visual, Big room y planificación colaborativa para mejorar la comunicación en el proyecto.
En el Capítulo V, se discuten los resultados durante los cuatro meses de implementación de la propuesta, logrando obtener una mejora de los indicadores del proyecto. Además, se analizan las Causas de No Cumplimiento mensuales obtenidas en el proyecto; así también en este capítulo se muestra una encuesta de satisfacción de los participantes de la reunión y se registran las conductas observadas luego del modelo de implementación de gestión de personas.
Finalmente, se brindan las conclusiones del trabajo y se dan recomendaciones de futuras investigaciones relacionadas al modelo propuesto.Construction projects today are subject to great complexity and uncertainty due to the multiple stakeholders that are part of their processes. In addition to this, they increasingly face shorter deadlines and costs, which causes many of them to face cost overruns and the contractual deadlines being exceeded. Faced with this problem, various methodologies have emerged in order to manage the cost and budget of the projects, but these methodologies focus more on the processes and not on the people, who are the ones who finally deliver the construction project. Thus, the following research proposes and implements a people management methodology based on the lean philosophy, which allows reducing uncertainty in a sports infrastructure project. The thesis work is divided into five chapters, as detailed below:
In Chapter I, a review is made of some proposals to manage people in construction projects, the problem is defined and the research objectives are established.
In Chapter II, a literary review is carried out on the concepts that will be studied in the research, the theory of lean Construction is developed, the basis of our people management model, and the Last Planner® System (LPS) is studied at a conceptual level. , identifying implementation problems and benefits, as it will be implemented in our people management model.
In Chapter III, the people management model is proposed and four people management models found in the literary review are reviewed. In addition, a people management model is proposed that will be detailed throughout the chapter and the theory of change management for the implementation of the model is explained. The model is made up of three parts, the first corresponding to people, where concepts from the perspective of linguistic action, collaboration, leadership and respect are reviewed, as the conceptual basis of the model. Then we move on to the processes where the use of visual management and LPS is proposed, this is where an implementation manual is developed for each of the LPS levels. The chapter ends with the last element of the model, which is technology and the use of BIM is proposed for monitoring tasks and the use of information technologies for better communication.
In Chapter IV, the implementation process of the proposal over four months is detailed and it is described how the different tools proposed in the project evolve from month to month, in this chapter the implementation of visual management, big room and collaborative planning to improve communication in the project.
In Chapter V, the results are discussed during the four months of implementation of the proposal, achieving an improvement in the project indicators. In addition, the monthly Causes of Non-compliance obtained in the project are analyzed; Also, in this chapter, a satisfaction survey of the meeting participants is shown and the behaviors observed after the people management implementation model are recorded.
Finally, the conclusions of the work are provided and recommendations for future research related to the proposed model are given.Tesi
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
