Los sistemas agroalimentarios locales se caracterizan por la diversidad de actores, prácticas y conocimientos, así como por las formas en que se configuran a partir de las escalas y geografías, dando lugar a múltiples expresiones y escenarios de análisis, discusión y reivindicación. Al respecto, los principales aportes y propuestas se han centrado tanto en visibilizar y sistematizar procesos que se aproximan a escenarios deseables de transformación, como a denunciar dinámicas de despojo de los medios de producción e imposición de lógicas agroindustriales. Sin embargo, estas expresiones analíticas se han organizado cada vez más en torno al análisis de los factores comunes a las transformaciones y embates, dejando de lado la visibilización de las diferencias y dando lugar a comprensiones agroalimentarias menos plurales. Por lo tanto, al margen de los casos paradigmáticos y de las grandes críticas, generalmente en la periferia de los sistemas agroalimentarios y de su entendimiento, existen comunidades, colectivos, familias y académicos(as) que, a través de prácticas y reflexiones cotidianas, intentan dialogar o construir realidades agrarias, productivas y alimenticias por fuera de los debates, agendas y reflectores políticos e intelectuales dominantes. Este libro se adentra en los márgenes agroalimentarios a través de un recorrido por México, en el que se exploran desde las semillas hasta las políticas públicas, pasando por los hogares rurales, así como por la reivindicación de conocimientos y saberes locales en relación con el territorio. Es así que la presente obra intenta visibilizar y valorar la diversidad de experiencias, luchas y posicionamientos que se llevan a cabo, espacial y alegóricamente, en los márgenes de las escalas analíticas, ofreciendo una perspectiva profunda sobre los retos y alcances desde la cotidianidad agroalimentaria del país.

Think about your data intelligently and ask the right questions Key FeaturesMaster data cleaning techniques necessary to perform real-world data science and machine learning tasksSpot common problems with dirty data and develop flexible solutions from first principlesTest and refine your newly acquired skills through detailed exercises at the end of each chapterBook Description Data cleaning is the all-important first step to successful data science, data analysis, and machine learning. If you work with any kind of data, this book is your go-to resource, arming you with the insights and heuristics experienced data scientists had to learn the hard way. In a light-hearted and engaging exploration of different tools, techniques, and datasets real and fictitious, Python veteran David Mertz teaches you the ins and outs of data preparation and the essential questions you should be asking of every piece of data you work with. Using a mixture of Python, R, and common command-line tools, Cleaning Data for Effective Data Science follows the data cleaning pipeline from start to end, focusing on helping you understand the principles underlying each step of the process. You'll look at data ingestion of a vast range of tabular, hierarchical, and other data formats, impute missing values, detect unreliable data and statistical anomalies, and generate synthetic features. The long-form exercises at the end of each chapter let you get hands-on with the skills you've acquired along the way, also providing a valuable resource for academic courses. What you will learnIngest and work with common data formats like JSON, CSV, SQL and NoSQL databases, PDF, and binary serialized data structuresUnderstand how and why we use tools such as pandas, SciPy, scikit-learn, Tidyverse, and BashApply useful rules and heuristics for assessing data quality and detecting bias, like Benford’s law and the 68-95-99.7 ruleIdentify and handle unreliable data and outliers, examining z-score and other statistical propertiesImpute sensible values into missing data and use sampling to fix imbalancesUse dimensionality reduction, quantization, one-hot encoding, and other feature engineering techniques to draw out patterns in your dataWork carefully with time series data, performing de-trending and interpolationWho this book is for This book is designed to benefit software developers, data scientists, aspiring data scientists, teachers, and students who work with data. If you want to improve your rigor in data hygiene or are looking for a refresher, this book is for you. Basic familiarity with statistics, general concepts in machine learning, knowledge of a programming language (Python or R), and some exposure to data science are helpful.

The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.

Illustrated with 10 images. This book will be a descriptive grammar of the Esperanto language invented by L. L. Zamenhof, which will be complete and comprehensive in regards to a) the grammar of Esperanto as first outlined by Zamenhof in Fundamento de Esperanto and other foundational documents, and b) Esperanto as it is spoken today by the most committed Esperantists. (Proposed reforms to the Esperanto language will be discussed if they have serious support from a significant fraction of Esperanto enthusiasts). This book was started practically on a dare from the August 2006 issue of Bob's Poetry Magazine, in which Robert Happelberg boasted that he could print a complete and comprehensive grammar of Esperanto in just one 6 by 7 inch page. While this is obviously wrong, it's not too far off the mark. When completed, this book will require several standard size (8.5 by 11 in the USA) pages, but will still be much shorter than a complete grammar of a natural language like English or Slovene. In view of this goal, the number of examples provided for each concept will be kept to a bare minimum. Those wishing to build their Esperanto vocabularies are also referred to the Esperanto textbooks. It is acceptable in the beginning to word the text in an accessible manner like in a textbook, but the goal should be for all the text to be technical with a full command of linguistic jargon.
