Yokes, hachas, and palmas are three pre-Columbian art forms that occur in a specific region of Mexico and Central America and apparently have no exact counterparts anywhere else. This volume focuses on these carved stone objects which have puzzled art historians and archaeologists since the mid-19th century. The corpus of data presented here, consisting of photo documentation, identification, and interpretation of 661 sculptures, was assembled by the two authors over many years, beginning in the early 1940s.

Get to grips with pandas by working with real datasets and master data discovery, data manipulation, data preparation, and handling data for analytical tasks Key Features Perform efficient data analysis and manipulation tasks using pandas 1.x Apply pandas to different real-world domains with the help of step-by-step examples Make the most of pandas as an effective data exploration tool Book DescriptionExtracting valuable business insights is no longer a ‘nice-to-have’, but an essential skill for anyone who handles data in their enterprise. Hands-On Data Analysis with Pandas is here to help beginners and those who are migrating their skills into data science get up to speed in no time. This book will show you how to analyze your data, get started with machine learning, and work effectively with the Python libraries often used for data science, such as pandas, NumPy, matplotlib, seaborn, and scikit-learn. Using real-world datasets, you will learn how to use the pandas library to perform data wrangling to reshape, clean, and aggregate your data. Then, you will learn how to conduct exploratory data analysis by calculating summary statistics and visualizing the data to find patterns. In the concluding chapters, you will explore some applications of anomaly detection, regression, clustering, and classification using scikit-learn to make predictions based on past data. This updated edition will equip you with the skills you need to use pandas 1.x to efficiently perform various data manipulation tasks, reliably reproduce analyses, and visualize your data for effective decision making – valuable knowledge that can be applied across multiple domains.What you will learn Understand how data analysts and scientists gather and analyze data Perform data analysis and data wrangling using Python Combine, group, and aggregate data from multiple sources Create data visualizations with pandas, matplotlib, and seaborn Apply machine learning algorithms to identify patterns and make predictions Use Python data science libraries to analyze real-world datasets Solve common data representation and analysis problems using pandas Build Python scripts, modules, and packages for reusable analysis code Who this book is for This book is for data science beginners, data analysts, and Python developers who want to explore each stage of data analysis and scientific computing using a wide range of datasets. Data scientists looking to implement pandas in their machine learning workflow will also find plenty of valuable know-how as they progress. You’ll find it easier to follow along with this book if you have a working knowledge of the Python programming language, but a Python crash-course tutorial is provided in the code bundle for anyone who needs a refresher.

First published in 1991, The Dictionary of Contemporary Politics of Central America and the Caribbean provides a guide to the most important organizations, figures, events and themes in the contemporary politics of Central America, Mexico, and the Caribbean. The countries covered include Mexico, Guatamala, Belize, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Cuba, Dominican Republic, Haiti, Jamaica, Trinidad and Tobago, Barbados, Grenada, St Vincent, St Lucia, Dominica, St Kitt’s-Nevis, Antigua and Puerto Rico. The background information supplied in the book explains how, for many in Central America, the guerrilla wars have merely been the intensification of a conflict previously fought by the likes of Nicaragua’s Sandino or the Salvadorean Farabundo Marti, and before them by the Indian leaders who resisted the Spanish settlement. Although first published in 1991, this book will be a valuable resource for journalists, students, diplomats, business people, and anyone else who is interested in the politics of this richly diverse continent.
