Factor Analysis and Dimension Reduction in R provides coverage, with worked examples, of a large number of dimension reduction procedures along with model performance metrics to compare them. Factor analysis in the form of principal components analysis (PCA) or principal factor analysis (PFA) is familiar to most social scientists. However, what is less familiar is understanding that factor analysis is a subset of the more general statistical family of dimension reduction methods.
The social scientist's toolkit for factor analysis problems can be expanded to include the range of solutions this book presents. In addition to covering FA and PCA with orthogonal and oblique rotation, this book's coverage includes higher-order factor models, bifactor models, models based on binary and ordinal data, models based on mixed data, generalized low-rank models, cluster analysis with GLRM, models involving supplemental variables or observations, Bayesian factor analysis, regularized factor analysis, testing for unidimensionality, and prediction with factor scores. The second half of the book deals with other procedures for dimension reduction. These include coverage of kernel PCA, factor analysis with multidimensional scaling, locally linear embedding models, Laplacian eigenmaps, diffusion maps, force directed methods, t-distributed stochastic neighbor embedding, independent component analysis (ICA), dimensionality reduction via regression (DRR), non-negative matrix factorization (NNMF), Isomap, Autoencoder, uniform manifold approximation and projection (UMAP) models, neural network models, and longitudinal factor analysis models. In addition, a special chapter covers metrics for comparing model performance.

This concise handbook presents a framework to help leaders across sectors understand what their role should be in an extreme crisis and supplements this understanding with practical advice.
Leadership is often presented as a kind of mastery—but no single person can master an extreme crisis event such as the COVID-19 pandemic. Leaders need a workable resource based on research and experience that can be accessed quickly and referenced easily to effectively handle crises and mitigate repercussions: This handbook is that resource. It begins with diagnostic tools to identify crisis types and leadership roles, then presents an easy-to-use matrix framework that allows readers to focus on the specific example-based section that best fits their role and the kind of crisis they face.

Extraordinary images by master macro photographer Levon Biss capture a vanishing world of insects from the collections of the American Museum of Natural History in New York
Insects are at once our most familiar fellow animals and the most mysterious. They appear to be indestructible, but globally, insect species are quietly disappearing in the sixth mass extinction that life on Earth is undergoing today. This joint project of photographer Levon Biss and the American Museum of Natural History contains indelible images of 40 extinct or endangered species in the museum's collection, selected from its vast holdings by a team of scientists. They range from imperiled old friends like the monarch butterfly and the nine-spotted ladybug to the remote Lord Howe Island stick insect of Australia, thought to be extinct for most of the 20th century until a tiny population was discovered and bred in captivity in 2001. All were sent to Biss's studio, where he created commanding portraits that can be enlarged 300-times lifesize to reveal vivid full-page details of form and color—a world invisible to our naked eyes. The result is a book that insists on the momentous significance of these small, mostly unknown creatures.

This book analyses and unpacks the term Feel by exploring its many definitions and examples in real life. Incorporating psychological theories and case studies, it offers a groundbreaking look into what it means to Feel and its importance in people's everyday lives.
Experiencing life without Feel has led to many deleterious performance, health, and wellbeing consequences. Exploring the Concept of Feel for Wellbeing and Performance takes a deep dive into the origins and definitions of Feel, asking what has happened to the Feel experience, and what people must do to recoup their Feel. With a highly accessible tone and clear structure, the book provides its readers with effective ways to improve performance and enhance wellbeing. The authors challenge the status quo of both performance science and wellbeing practices and begin a conversation on why people should be more proactive when it comes to their Feel.

Do snakes and salamanders fascinate you or make you squeamish? Have you ever listened closely to the birds chirping in your neighborhood? Can you identify the flowers growing in Philadelphia's urban parks? (Moreover, are the mushrooms safe to eat?) Exploring Philly Nature is amateur naturalist, urban herper,* and Grid contributor Bernard Brown's handy guide to experiencing the flora and fauna in Philly.
This compact illustrated volume contains 52 activities from birding, (squirrel) fishing, and basement bug-hunting to joining a frog call survey and visiting a mussel hatchery. Brown encourages kids (as well as their parents) to connect with the natural world close to home. Each entry contains information on where and when to participate, what you will need (even if it is only patience), and tips on clubs and organizations to contact for access.

Exploring Modeling with Data and Differential Equations Using R provides a unique introduction to differential equations with applications to the biological and other natural sciences. Additionally, model parameterization and simulation of stochastic differential equations are explored, providing additional tools for model analysis and evaluation. This unified framework sits "at the intersection" of different mathematical subject areas, data science, statistics, and the natural sciences. The text throughout emphasizes data science workflows using the R statistical software program and the tidyverse constellation of packages. Only knowledge of calculus is needed; the text's integrated framework is a stepping stone for further advanced study in mathematics or as a comprehensive introduction to modeling for quantitative natural scientists.
The text will introduce you to:

The book aims to unravel some of the nature's mysteries by correlating the nature of fields and the transformations in their symmetries. It begins with a brief background on the foundation of symmetry and its meaning in fields such as architecture, mathematics, and physics. A special focus of the book is on the concept of symmetries in electromagnetism and explicit symmetry breaking which generates radiation. Despite extensive developments of the phenomenon of broken symmetry in different domains of physics, it has yet to be applied within the context of classical electromagnetism and related engineering applications in a broader context. For example, the mechanism of generation of electromagnetic radiation from thin films and non-metallic materials at radio frequencies remains poorly understood and the book offers a lucid exposition to it.
This second edition builds on the introduction to the concept of symmetries in electromagnetism and explicit symmetry breaking. It addresses some of the recent developments in the field of radiation from magneto-electric materials and ferroelectric materials and correlates them to the nature of symmetries in physical systems. New chapters include coverage of radiation mechanisms from magnetoelectric materials, the role of gauge fields in radiation, and antenna design and symmetries.
