Resumen en español

Nueva edición de la obra de los Dres. Josep Mª Argimón y Josep Jiménez, en la que se mantiene la filosofía que les llevó a escribir la primera edición en el año 1991. Así, el hilo conductor de la obra sigue siendo la elaboración de un protocolo de estudio, de forma que aquellos profesionales que se enfrentan al reto de diseñar una investigación puedan seguir paso a paso las diferentes fases, desde los planteamientos iniciales y la definición del objetivo hasta la planificación de la estrategia de análisis. La obra combina los contenidos teóricos con temas más prácticos, como la solicitud de una ayuda para la financiación de la investigación, una guía para la elaboración de los protocolos de estudio, los preparativos para la puesta en marcha y tablas para el cálculo del tamaño de la muestra en la mayoría de las situaciones. Métodos de investigación clínica y epidemiológica mantiene el material complementario online, renovado y actualizado como son las preguntas tipo test, los casos de estudio, el glosario de términos y los recursos docentes (presentaciones PowerPoint de distintos temas relacionados con el libro para que puedan ser utilizadas en seminarios o sesiones clínicas). Guía práctica y de referencia para el estudio de los fundamentos del método científico y el diseño y desarrollo de un protocolo de estudio, así como para la lectura e interpretación crítica de artículos científicos. El objetivo de la obra es que el lector sea capaz de elaborar un protocolo de estudio, de modo que aquellos profesionales que se enfrentan al reto de diseñar una investigación puedan seguir paso a paso las diferentes fases, desde los planteamientos iniciales, la definición del objetivo y la realización de una búsqueda bibliográfica eficiente, hasta la planificación de la estrategia de análisis.

Los autores combinan los contenidos teóricos con capítulos y temas tan prácticos como la solicitud de una ayuda para la financiación de la investigación, una guía para la elaboración de los protocolos de estudio, su puesta en marcha, cálculos prácticos del tamaño muestral, etc. Se incorpora material complementario online, renovado y actualizado como son casos de estudio, un glosario de términos en español e inglés, así como una batería de preguntas abiertas de cálculo, de elección múltiple y didácticas.

Resumen en español

En años recientes se han realizado descubrimientos sobre la microbiota intestinal y su relación con enfermedades y síndromes metabólicos en los humanos, además de que regulan algunas funciones fisiológicas como la respuesta inmune y señalización molecular. Estos descubrimientos han sido posibles mediante análisis moleculares de nueva generación como la metagenómica. Para realizar estos estudios se utiliza material genético a partir de la materia fecal humana, que es de recolección no invasiva para el donador. La extracción de ADN se vuelve difícil de realizar debido a la diversidad de material genético contenido en la muestra, por lo que es importante instaurar un método que asegure la extracción de ADN de alto rendimiento para realizar estudios moleculares como el análisis metagenómico. El objetivo de este trabajo fue analizar la metodología de extracción de ADN haciendo un comparativo entre dos tipos de detergentes utilizados en la lisis celular para determinar cuál de los dos demuestra un mejor desempeño en el proceso de extracción. La comparación se hizo con base a la concentración y pureza de ADN obtenido por medio de espectrofotometría y la calidad cualitativa de ADN determinada por electroforesis en gel de agarosa. Los detergentes utilizados fueron CTAB y SDS. Los resultados demostraron que el CTAB es un detergente con mayor rendimiento para la extracción de ADN metagenómico.

Resumen en español

La metodología de la investigación para realizar una tesis de maestría, e incluso de doctorado que presenta este libro, se distingue por la sencillez con que se exponen las competencias que debe tener un investigador y los pasos a seguir para estructurar una tesis. La idea de investigación que se expone aquí se basa en el método LART, el cual se ilustra con ejemplos. A partir de allí, el autor explica la congruencia en el planteamiento de la investigación, continúa con la revisión del estado del arte, la identificación de las variables o categorías de análisis, los distintos tipos de investigación que existen, los tipos de hipótesis, el diseño de la investigación, lo que es un modelo y la importancia de usar alguno para sustentar una guía de entrevista, de observación o documental. Para finalizar, se resumen los métodos estadísticos usados en la ciencia moderna, y se analiza la estructura y el estilo de trabajo científico.

Resumen en inglés

Reliable, standardized and replicable methodologies for quickly assessing key ecosystem values in the field are essential for conservation planning and decision-making at the local to regional scale at which most threats occur. Rapid biological assessments are a cost-effective solution to this problem, providing data in a timely manner to address a wide range of conservation needs, and in particular to establish a baseline that can be used to detect changes over time. A great deal of high level methodological guidance exists, but most lack practical detail. A few books describe relatively comprehensive sampling methods but do not focus on a core set of standardized methods, making it difficult to decide which protocols to adopt. Other publications are available with lengthy, detailed guidance on sampling individual taxa. The editor believes this is the first book that focuses exclusively on a concise, practical set of standardized protocols for a wide range of taxa. This is no simple task. Many scientists tend to employ their own individualized, often opportunistic, approachesfor finding as many species as possible in a short time, sometimes honed through decades of personal experience. These contributions are invaluable, yet do not address many conservation requirements. While not intended to replace these methods, the identification of a core, at-a-minimum set of standardized methods, including innovative and automated approaches where applicable, is of great importance for making the results of rapid surveys comparable and replicable across sites and over time. Typically, rapid assessments require at least one week per site. A critical and often unanswered question in baseline assessments is how to know when sampling effort is sufficient. We have addressed this question with representative species accumulation curves and analyses in each individual chapter.

The focus of this book is on tropical terrestrial and freshwater ecosystems worldwide, although most methods should be applicable in temperate zones as well. It is not possible to sample all taxonomic groups during a rapid survey. In this book, we describe methods for major taxonomic groups (plants, vertebrates), as well as a select set of invertebrates that represent cost-effective indicator taxa and play important ecological roles. This book represents a consensus of multiple experts for each taxonomic group, including intensive peer review. It is expected that a future edition of this book will include methods for marine taxa, various ecosystem services, as well as social assessments. A separate chapter on analytical approaches or data management is not included, as these are already well covered in other publications.

Resumen en inglés

4th edition of this classic Ecology text Computational methods have largely been replaced by descriptions of the available software Includes procedure information for R software and other freely available software systems Now includes web references for equipment, software and detailed methodologies The first edition of this book was published in 1966 and became an instant classic text. The third edition was published in 2000 authored by Professors Southwood and Henderson. The availability of computer programs for many aspects of analysis of ecological data has continued to transform the way ecologists work. This will result in some important changes in the next (4th) edition. Many of the computational methods described in detail in the 3rd edition will be omitted and replaced with a description of the available software with brief descriptions of use and where to obtain it. In particular, reference will be made to procedures available in R and other freely available software systems. I would also like to add some photographs of equipment in use. This would avoid lengthy descriptions of apparatus. There needs to be far more references to web resources including equipment suppliers, software downloads and detailed methodologies. I will also ensure reference is made to suppliers in non-western countries e.g. Japan. Recent references will be added to all chapters. Generally, references to methodologies which are no longer used will be removed. However, older references to techniques still in use will be kept to ensure the work acts as a good reference to the development of ecological methods. I intend to ensure that the 4th edition enables younger readers to access older literature, which is still invaluable though often ignored.

It is planned that there will be little increase in the overall size of the work. Effort will be expended in making the text more accessible to advanced undergraduate and young post-graduate students. The first edition of this book was an undergraduate textbook (everyone on my course was expected to own their own copy). The 3rd edition had become an advanced text for graduate students and experienced researchers. While aiming to keep the 4th edition useful to experienced researchers, I aim to ensure that all chapters have text which is accessible and useful to students.

Resumen en frances

Les méthodes qualitatives occupent une place grandissante en sciences humaines et sociales, constituant depuis leurs origines américaines un courant aussi riche que diversifié. Cet ouvrage, véritable manuel, permet d’appréhender aussi bien l’histoire que les enjeux épistémologiques et applications pratiques de ces méthodes dans leur diversité (analyses thématiques, à l’aide des catégories, en mode écriture…). Il cible toute la fécondité du dénominateur commun à ces méthodes : une démarche rigoureuse de reformulation, d’explicitation ou de théorisation des données d’enquête participant de la découverte et de la construction de sens. Cette 3e édition a été augmentée de deux nouveaux chapitres et a fait l'objet de profonds remaniements.

Resumen en español

No son pocos los obstáculos que estudiantes, tesistas e investigadores enfrentan para culminar sus trabajos, pero hay uno que se encuentra en el centro de todos y que es el gran ausente en los libros de metodología: el estudio de las relaciones entre el modo de investigación y el de exposición. La relevancia del tema es indudable, puesto que la difusión de los resultados es inherente a la tarea misma de investigar; llenar ese vacío es la mayor aportación de esta obra.Loa autores son investigadores que han concluido y escrito sus trabajos de tesis con éxito. Ellos nos comparten, narran y explican las soluciones que hallaron para resolver la tensión existente entre la complejidad de la información procesada y la comunicación de los hallazgos de investigación de manera clara y sencilla. Con sus experiencias nos muestran que si la investigación se orienta a descubrir qué pasa o ha pasado en realidad (contenido), la exposición es básicamente una caja de herramientas o de estrategias narrativas más o menos eficaces y seductoras, de las que se dispone para explicar y exponer los resultados (forma).Si transitar del mundo de investigación al de exposición representa un ejercicio limite que determina el éxito o el fracaso, este libro-que prosigue a lo propuesto en El helicoide de la investigación: metodología en tesis de ciencias sociales (Flacso México, 2013)-nos orienta sobre cómo convertir la investigación en una narración coherente, esto es, sobre cómo llevar el trabajo de investigar al arte de exponer para ser finalmente publicado.
