| dichotomous key definition science: Science for Cultural Heritage Claudio Tuniz, 2010 The aim of the conference was to discuss the contribution of physics and other sciences in archaeological research and in the preservation of cultural heritage. Considering that the mission of ECSAC is to promote the interaction among the diverse cultures of the peoples from the lands on the Adriatic and Ionian seas, it is apt that the major themes were related to the rich history and pre-history of this region - from Greek-Roman archaeology on the eastern Adriatic coasts to the palaeoanthropology of the Neanderthals of the Vindija caves in Croatia, from the Roman city of Aquileia to the pleistocenic cave of Homo heidelbergensis in the Karst of Visogliano (Trieste), from the Roman ship Julia Felix of the Grado lagoon to the ancient bronze Apoxyomenos of the Veli Loscaron;inj waters. A variety of scientific disciplines provide tools and methods that are crucial in reconstructing humanity's past and in preserving material remains that witness the evolution of human culture. Geology reconstructs the history of terrestrial environments, critical for the evolution and dispersal of humans. Chemistry explains reactions that modify materials left by human activities, including the destructive effects of pollution. Biology has a critical role in archaeology, particularly with the recent advance in analysis of DNA in ancient organic materials. |
| dichotomous key definition science: Typologies and Taxonomies Kenneth D. Bailey, 1994-06-13 How do we group different subjects on a variety of variables? Should we use a classification procedure in which only the concepts are classified (typology), one in which only empirical entities are classified (taxonomy), or some combination of both? In this clearly written book, Bailey addresses these questions and shows how classification methods can be used to improve research. Beginning with an exploration of the advantages and disadvantages of classification procedures including those typologies that can be constructed without the use of a computer, the book covers such topics as clustering procedures (including agglomerative and divisive methods), the relationship among various classification techniques (including the relationship of monothetic, qualitative typologies to polythetic, quantitative taxonomies), a comparison of clustering methods and how these methods compare with related statistical techniques such as factor analysis, multidimensional scaling and systems analysis, and lists classification resources. This volume also discusses software packages for use in clustering techniques. |

| dichotomous key definition science: Forensic Plant Science Jane H Bock, David O. Norris, 2015-11-17 Forensic botany is the application of plant science to the resolution of legal questions. A plant's anatomy and its ecological requirements are in some cases species specific and require taxonomic verification; correct interpretation of botanical evidence can give vital information about a crime scene or a suspect or victim. The use of botanical evidence in legal investigations in North America is relatively recent. The first botanical testimony to be heard in a North American court concerned the kidnapping and murder of Charles Lindbergh's baby boy and the conviction of Bruno Hauptmann in 1935. Today, forensic botany encompasses numerous subdisciplines of plant science, such as plant anatomy, taxonomy, ecology, palynology, and diatomology, and interfaces with other disciplines, e.g., molecular biology, limnology and oceanography.Forensic Plant Science presents chapters on plant science evidence, plant anatomy, plant taxonomic evidence, plant ecology, case studies for all of the above, as well as the educational pathways for the future of forensic plant science. - Provides techniques, collection methods, and analysis of digested plant materials - Shows how to identify plants of use for crime scene and associated evidence in criminal cases - The book's companion website: http://booksite.elsevier.com/9780128014752, will host a microscopic atlas of common food plants |

| dichotomous key definition science: The SAGE Encyclopedia of Communication Research Methods Mike Allen, 2017-04-11 Communication research is evolving and changing in a world of online journals, open-access, and new ways of obtaining data and conducting experiments via the Internet. Although there are generic encyclopedias describing basic social science research methodologies in general, until now there has been no comprehensive A-to-Z reference work exploring methods specific to communication and media studies. Our entries, authored by key figures in the field, focus on special considerations when applied specifically to communication research, accompanied by engaging examples from the literature of communication, journalism, and media studies. Entries cover every step of the research process, from the creative development of research topics and questions to literature reviews, selection of best methods (whether quantitative, qualitative, or mixed) for analyzing research results and publishing research findings, whether in traditional media or via new media outlets. In addition to expected entries covering the basics of theories and methods traditionally used in communication research, other entries discuss important trends influencing the future of that research, including contemporary practical issues students will face in communication professions, the influences of globalization on research, use of new recording technologies in fieldwork, and the challenges and opportunities related to studying online multi-media environments. Email, texting, cellphone video, and blogging are shown not only as topics of research but also as means of collecting and analyzing data. Still other entries delve into considerations of accountability, copyright, confidentiality, data ownership and security, privacy, and other aspects of conducting an ethical research program. Features: 652 signed entries are contained in an authoritative work spanning four volumes available in choice of electronic or print formats. Although organized A-to-Z, front matter includes a Reader’s Guide grouping entries thematically to help students interested in a specific aspect of communication research to more easily locate directly related entries. Back matter includes a Chronology of the development of the field of communication research; a Resource Guide to classic books, journals, and associations; a Glossary introducing the terminology of the field; and a detailed Index.

| dichotomous key definition science: Data Architecture: A Primer for the Data Scientist W.H. Inmon, Daniel Linstedt, Mary Levins, 2019-04-30 Over the past 5 years, the concept of big data has matured, data science has grown exponentially, and data architecture has become a standard part of organizational decision-making. Throughout all this change, the basic principles that shape the architecture of data have remained the same. There remains a need for people to take a look at the bigger picture and to understand where their data fit into the grand scheme of things. Data Architecture: A Primer for the Data Scientist, Second Edition addresses the larger architectural picture of how big data fits within the existing information infrastructure or data warehousing systems. This is an essential topic not only for data scientists, analysts, and managers but also for researchers and engineers who increasingly need to deal with large and complex sets of data. Until data are gathered and can be placed into an existing framework or architecture, they cannot be used to their full potential. Drawing upon years of practical experience and using numerous examples and case studies from across various industries, the authors seek to explain this larger picture into which big data fits, giving data scientists the necessary context for how pieces of the puzzle should fit together. - New case studies include expanded coverage of textual management and analytics - New chapters on visualization and big data - Discussion of new visualizations of the end-state architecture |

| dichotomous key definition science: Core Sociological Dichotomies Chris Jenks, 1998-07-08 In this sociology text the contributors provide an introduction to the subject without over-simplifying or `writing-down′ to their audience. The book aims to furnish undergraduates with the knowledge that will help them to understand and practice sociology and also to develop a self-perpetuating sociological imagination to enable them to think through new issues and new problems. It consists of a series of specially commissioned chapters around binary or dichotomous themes. Although many sociologists are critical of dichotomous models of sociological theory and research, the device crops up again and again in the history and practice of the subject. Jenks and his colleagues use the dichotomies to situate students in current sociological arguments and topical debates. For example, by examining contradictory pairs of concepts like structure/agency, local/global, continuity/change, students are introduced to alternative explanations for aspects of human conduct over a whole series of issues. |
| dichotomous key definition science: Practical Statistics for Data Scientists Peter Bruce, Andrew Bruce, 2017-05-10 Statistical methods are a key part of of data science, yet very few data scientists have any formal statistics training. Courses and books on basic statistics rarely cover the topic from a data science perspective. This practical guide explains how to apply various statistical methods to data science, tells you how to avoid their misuse, and gives you advice on what's important and what's not. Many data science resources incorporate statistical methods but lack a deeper statistical perspective. If you’re familiar with the R programming language, and have some exposure to statistics, this quick reference bridges the gap in an accessible, readable format. With this book, you’ll learn: Why exploratory data analysis is a key preliminary step in data science How random sampling can reduce bias and yield a higher quality dataset, even with big data How the principles of experimental design yield definitive answers to questions How to use regression to estimate outcomes and detect anomalies Key classification techniques for predicting which categories a record belongs to Statistical machine learning methods that “learn” from data Unsupervised learning methods for extracting meaning from unlabeled data |

Wilson The Sibley Guide to Trees is an astonishingly elegant guide to a complex subject. It condenses a huge amount of information about tree identification—more than has ever been collected in a single book—into a logical, accessible, easy-to-use format. With more than 4,100 meticulous, exquisitely detailed paintings, the Guide highlights the often subtle similarities and distinctions between more than 600 tree species—native trees as well as many introduced species. More than 500 maps show the complete range, both natural and cultivated, for nearly all species. No other guide has ever made field identification so clear. Highlighted features include: • leaves (including multiple leaf shapes and fall leaf color) • bark • needles • cones • flowers • fruit • twigs • silhouettes Trees are arranged taxonomically, with all related species grouped together. By focusing on the fundamental characteristics of, for example, oaks or chestnuts or hickories, the Guide helps the user recognize these basic species groups the same way birders recognize thrushes, warblers, or sparrows. In addition, there are essays on taxonomy, on the cultivation of trees, and on conservation issues, reflecting Sibley’s deep concern with habitat preservation and environmental health. An important contribution to our understanding of the natural world, The Sibley Guide to Trees is a necessity for every tree lover, traveler, and naturalist. |

| dichotomous key definition science: Science and Judgment in Risk Assessment National Research Council, Division on Earth and Life Studies, Board on Environmental Studies and Toxicology, Commission on Life Sciences, Committee on Risk Assessment of Hazardous Air Pollutants, 1994-01-01 The public depends on competent risk assessment from the federal government and the scientific community to grapple with the threat of pollution. When risk reports turn out to be overblownâ€or when risks are overlookedâ€public skepticism abounds. This comprehensive and readable book explores how the U.S. Environmental Protection Agency (EPA) can improve its risk assessment practices, with a focus on implementation of the 1990 Clean Air Act Amendments. With a wealth of detailed information, pertinent examples, and revealing analysis, the volume explores the default option and other basic concepts. It offers two views of EPA operations: The first examines how EPA currently assesses exposure to hazardous air pollutants, evaluates the toxicity of a substance, and characterizes the risk to the public. The second, more holistic, view explores how EPA can improve in several critical areas of risk assessment by focusing on cross-cutting themes and incorporating more scientific judgment. This comprehensive volume will be important to the EPA and other agencies, risk managers, environmental advocates, scientists, faculty, students, and concerned individuals. |
