January 2018Plant Nutrition, Second Edition
by Alex C. Wiedenhoeft, Series Editor: William G. Hopkins
The mineral nutrients of plants play key roles in plant growth and development, forming the underpinnings of the past, present, and future of agriculture. Plants with insufficient nutrients exhibit symptoms of sickness that can be confused with infectious plant diseases. The nutrients needed by plants are taken from the soil by the roots, and in many plants, the roots also form associations with other organisms that help them more efficiently colonize the soil or provide nutrients to the plant. All facets of plant nutrition, from the effect of nutrients on the plant to the role of plants in the global cycling of nutrients, impact the ways in which humans use and depend on plants for most aspects of our existence. Plant Nutrition, Second Edition addresses the basic chemistry, biology, physiology, and ecology of plant nutrition and shows how these topics relate to humans on a personal, social, and global scale.

January 2018Plant Biotechnology, Second Edition
by William G. Hopkins; Series Editor: William G. Hopkins
Over the past 25 years, terms like genetic modification, genetic engineering, recombinant DNA technology, and biotechnology have become commonplace in the news and in the public vocabulary. But biotechnology has in fact been practiced for thousands of years, with the aim of harnessing organisms for processing food and making useful products. Since the 1980s, however, recombinant DNA technology has given us the ability to modify organisms in the most fundamental way. The modification of plants by these new techniques has unleashed a storm of public controversy worldwide. Plant Biotechnology, Second Edition brings perspective to the discussion. Tracing the history of biotechnology, from its origins in antiquity through its foundations as a science in the work of Louis Pasteur to the birth of modern genetic engineering, this eBook describes traditional uses for plants, reveals how they are genetically engineered, and explains how new technology compares with conventional ways of generating new food plants. Readers will find that this accessible introduction dispels some of the myths surrounding genetic engineering, clearly presents the current impact and future potential of genetically modified plants, and provides a balanced look at the risks and benefits of biotechnology.

January 2018Plant Diversity, Second Edition
by J. Phil Gibson and Terri R. Gibson, Series Editor: William G. Hopkins
Plants feed us, clothe us, provide us with the oxygen we breathe, and buffer our environment against change. In short, plants make life possible. Yet scientists estimate that more than 10 percent of the world's approximately 300,000 plant species are at risk of extinction, and huge swaths of tropical forests and other plant communities are being decimated daily. Plant Diversity, Second Edition surveys the world's plant diversity, from green algae through flowering plants, and presents the fascinating natural history and diversity of green plants in a taxonomic and evolutionary context. This title also asks and answers the questions: Why are there so many plant species in the world? And how can so many plants grow together in a given patch of prairie, forest, or wetland? Through the study of plant diversity, students will gain an appreciation of the natural world far beyond the classroom and the study of botany, to an understanding of how our actions impact the world around us. Plant Diversity, Second Edition is suitable as a supplementary text for a biology course or as recreational reading for the interested student.

January 2018Plant Cells and Tissues, Second Edition
by Nicholas Stephens, Series Editor: William G. Hopkins
Plants comprise millions of cells that work together as tissues to move materials throughout the body, gather water and minerals from the soil, and convert carbon dioxide into sugar by using energy from the sun. Plant Cells and Tissues, Second Edition takes a focused approach to the study of plant processes by examining this subject from its smallest unit, the cell. This volume also answers questions such as: How do tiny seeds grow into towering trees? How do nettles deliver such painful stings? And how do roots know which way is down? Some of the topics discussed include interesting aspects of plant cell biology, such as cell division and what makes a plant wilt. It also highlights special adaptations that plants have made to survive in harsh environments, including the plant science behind the survival of the spiny cacti of deserts and the carnivorous insect traps of acidic bogs. This reference is a vital tool for students and teachers of plant biology.

January 2021Practical R for Biologists
An Introduction
by Donald Quicke, Buntika A Butcher, Rachel Kruft Welton
R is a freely available, open-source statistical programming environment which provides powerful statistical analysis tools and graphics outputs. R is now used by a very wide range of people; biologists (the primary audience of this book), but also all other scientists and engineers, economists, market researchers and medical professionals. R users with expertise are constantly adding new associated packages, and the range already available is immense.This text works through a set of studies that collectively represent almost all the R operations that biology students need in order to analyse their own data. The material is designed to serve students from first year undergraduates through to those beginning post graduate levels. Chapters are organized around topics such as graphing, classical statistical tests, statistical modelling, mapping, and text parsing. Examples are based on real scientific studies, and each one covers the use of more R functions than those simply necessary to get a p-value or plot.The book walks the reader through the data analysis process, starting with very simple plots, and continuing through more complex analyses and programming. It shows how to deal with issues such as error messages that can be confronting for beginners, in order to set students up for a successful scientific career using R.Collectively the authors have a vast amount of teaching experience which they apply here to make the passage into R programming as gentle and easy as possible, whilst guiding the reader to tackle quite complicated programming. Table of contents 1: How to Use this Book 2: Installing and Running R 3: Very Basic R Syntax 4: First Simple Programs and Graphics 5: The Dataframe Concept 6: Plotting Biological Data in Various Ways 7: The Grammar of Graphics Family of Packages 8: Sets and Venn diagrams 9: Statistics: Choosing the Right Test 10: Commonly Used Measures and Statistical Tests 11: Regression and Correlation Analyses 12: Count Data as Response Variable 13: Analysis of Variance (ANOVA) 14: Analysis of Covariance (ANCOVA) 15: More Generalised Linear Modelling 16: Monte Carlo Tests and Randomisation 17: Principal Components Analysis 18: Species Abundance, Accumulation and Diversity Data 19: Survivorship 20: Dates and Julian Dates 21: Mapping and Parsing Text Input for Data 22: More on Manipulating Text 23: Phylogenies and Trees 24: Working with DNA Sequences and other character data 25: Spacing in Two Dimensions 26: Population Modelling Including Spatially Explicit Models 27: More on “apply” Family of Functions – Avoid Loops to get More Speed 28: Food webs and simple graphics 29: Adding Photographs 30: Standard Distributions in R 31: Reading and Writing Data to and from Files

December 2023Verantwortung
Philosophische Grundlagentexte
by Christoph Halbig, Jörg Löschke, Philipp Schwind
Die Zuschreibung von Verantwortung für unsere Handlungen ist ein zentraler Bestandteil unserer moralischen Praxis. Aber sie wirft schwierige philosophische Fragen auf. Müssen wir beispielsweise über einen freien Willen verfügen, um für unsere Handlungen verantwortlich zu sein? Ist Verantwortung ein einheitliches Phänomen oder gibt es verschiedene Arten von Verantwortung? Und können wir nur für unsere Taten verantwortlich sein oder beispielsweise auch für unsere Überzeugungen? Der Band versammelt – zum Teil erstmals in deutscher Übersetzung – die zentralen Texte der philosophischen Debatte über Verantwortung, u. a. von Stephen Darwall, Harry G. Frankfurt, H. L. H. Hart, Thomas Nagel, Peter Strawson, Susan Wolf und Iris Marion Young.

Robust health care systems are paramount for the health, security, and prosperity of people and countries as a whole. This book provides for the first time a chronicle of the struggle for, and eventual success of, universal health coverage (UHC) in Tanzania. Beginning with an introduction to primary health care in the country, from its historical foundations to the major milestones of implementation, this book then considers stewardship of this important aspect of health systems over time. Written in a way to allow the application of lessons learned to other countries' contexts, this book covers: - Policy and governance issues such as leadership, human resources, and financing of health systems; - Practical aspects of health system delivery, including supply chains, community care, new technologies, and the integration of services for particular population groups; - The impact and mitigation of global events on health systems, such as resilience and preparedness in the light of disease outbreaks or climate change, and social, commercial, and political influences. Concluding with a look to the future, forecasting the changes and new solutions needed to adapt to a changing world, this book is a valuable reference for policy makers, global health practitioners, health system managers, researchers, students, and all those with an interest in primary health care and reforms - both in Tanzania and beyond.

Humanities & Social SciencesJanuary 2020The life–cycle in Western Europe, c.1300–c.1500
by S. H. Rigby, Deborah Youngs
This is the first study to examine the entire life cycle in the Middle Ages. Drawing on a wide range of secondary and primary material, the book explores the timing and experiences of infancy, childhood, adolescence and youth, adulthood, old age and, finally, death. It discusses attitudes towards ageing, rites of passage, age stereotypes in operation, and the means by which age was used as a form of social control, compelling individuals to work, govern, marry and pay taxes. The wide scope of the study allows contrasts and comparisons to be made across gender, social status and geographical location. It considers whether men and women experienced the ageing process in the same way, and examines the differences that can be discerned between northern and southern Europe. The fourteenth and fifteenth centuries suffered famine, warfare, plague and population collapse. This fascinating consideration of the life cycle adds a new dimension to the debate over continuity and change in a period of social and demographic upheaval.
