The founder of Girls Who Code and bestselling author of Brave, Not Perfect confronts the ';big lie' of corporate feminism and presents a bold plan to address the burnout and inequity harming America's working women today.We told women that to break glass ceilings and succeed in their careers, all they needed to do is dream big, raise their hands, and lean in. But data tells a different story. Historic numbers of women left their jobs in 2021, resulting in their lowest workforce participation since 1988. Women's unemployment rose to nearly fifteen percent, and globally women lost over $800 billion in wages. Fifty-one percent of women say that their mental health has declined, while anxiety and depression rates have skyrocketed. In this urgent and rousing call to arms, Reshma Saujani dismantles the myth of ';having it all' and lifts the burden we place on individual women to be primary caregivers, and to work around a system built for and by men. The time has come, she argues, for innova

A is for Atmosphere, B is for Biodiversity, C is for Conservation, D is for, well...you get the picture. This delightful concept book teaches young readers the ABCs of the natural world around us (and how to protect it). From jungles to recycling to wildlife preserves, each letter of the alphabet is represented by a word and image that reflects everything from the rainforest to the savannah to the depths of the ocean, as well as animal life across the continents. Readers will be inspired to join the movement to conserve species and find out how they can make a difference (because you're never too young to start saving the world!).

This book determines what roles business people in Taiwan have actually played in the development of economic diplomacy for Taiwan. It shows that they did nothing to prevent the crisis of 1995â "1996, and that it was only when the US intervened that the crisis subsided. The book looks at the impact of the international system on the economic diplomacy of Taiwan, and represents a major contribution to the field of international relations by explicating a three-level analysis of the external relations of Taiwan. Using a bottom-up approach, it explains the activities of business people in Taiwan and clarifies their influence beyond Taiwan. The book argues that such activities have significant economic impacts and that their influence cannot be ignored.

This book explores why Nepal's hydropower sector is one of its few development success stories. Unlike most other 'developing' countries, in Nepal local firms design and build hydropower facilities using Nepali engineers, builders and labor. Nepal has largely avoided the trap whereby most poor countries are forced to accept energy infrastructure projects that are foreign designed, funded and built – typically resulting in debt, dependency and unsustainability. It traces the struggle between two competing development paradigms: one that emphasizes gradual national human capacity building – at the expense of speed and efficiency – and another that emphasizes rapid, large-scale infrastructure building – at the risk of unsustainability and dependency. At stake is whether what passes for 'development' benefits the countries in which it occurs, or the banks and investors that finance capital-intensive projects. What Went Right brings a vision for sustainable development into vigorous convers

Around the world, populist parties have sprung up in formerly and formally liberal-democratic polities, challenging their existing political parties and leaders, and frequently overwhelming them. These challenges and successes were rarely predicted, arriving so soon after the wave of liberal democratic and constitutional enthusiasms, proclamations and institution-building which peaked in the 1990s. Bringing together scholars from law, political science and philosophy, this collection explores the character of contemporary populisms and their relationships to constitutional democracy. With contributors from around the world, it offers a diverse range of nuanced perspectives on populism as a global phenomenon. Using comparative and multi-disciplinary techniques, this book considers the specifics and similarities of populisms, and raises general questions about their nature and potential futures.

Why do some people engage in serial killing for sexual pleasure? This book considers the phenomenon of sexual serial killing from the perspective of motivation theory, as advanced in psychology and neuroscience. By examining biological, psychological and social determinants, it develops a model of sexual killing that integrates widely dispersed existing literature. The first part of the book reviews scientific data and theories, while the second part presents biographical sketches of 80 sexual killers and links their early development and later killing to current theoretical understanding. The book examines cases of serial killers from the USA, Western Europe, Iran, Australia and South Africa, and it also includes an account of killers from the USSR, made available to non-Russian speakers for the first time. Deliberately written to avoid jargon, Understanding Sexual Serial Killing is accessible to students, scholars and professionals across psychology, sociology, forensic science and l

Extensively updated for the second edition, this handy guide covers the safety engineering of ship-shaped offshore installations at every stage of design, construction, operation, lifetime healthcare and decommissioning. New sections cover additional types of offshore structures, including offshore power plants, as well as cutting-edge technologies and all the latest advances in the field. The text focuses on minimising accidents and the effects of extreme conditions, with new chapters covering earthquakes, hurricanes and terrorist attacks, as well as traditional types of accidental events such as hull girder collapse, collisions, fires and explosions. This is an invaluable resource for students who will be approaching the subject for the first time as well as practising engineers and researchers.

Does protest influence political representation? If so, which groups are most likely to benefit from collective action? The Advantage of Disadvantage makes a provocative claim: protests are most effective for disadvantaged groups. According to author LaGina Gause, legislators are more responsive to protesters than non-protesters, and after protesting, racial and ethnic minorities, people with low incomes, and other low-resource groups are more likely than white and affluent protesters to gain representation. Gause also demonstrates that online protests are less effective than in-person protests. Drawing on literature from across the social sciences as well as formal theory, a survey of policymakers, quantitative data, and vivid examples of protests throughout U.S. history, The Advantage of Disadvantage provides invaluable insights for scholars and activists seeking to understand how groups gain representation through protesting.

Plastic pollution is a global problem that defies a singular solution. Our Plastic Problem and How to Solve It considers plastic's harm to the environment, from its production to its disposal, and offers a spectrum of solutions that require action by local and federal governments, businesses and non-profits, and individuals. Using specific examples and case studies, the book describes the history and chemistry of plastic, illustrates its harms, and points toward specific legislation and policies to offer concrete solutions. Plastic pollution is ubiquitous and has impacts on soil, food, air, and water. To solve our plastic problem, collaboration across disciplines will be critical; innovations in science, law, and design will be essential. The book demonstrates the need to approach environmental problems from an interdisciplinary lens, and will benefit anyone interested in learning more about the harms and solutions associated with plastic pollution.

Compliance, or the behavioral response to legal rules, has become an important topic for academics and practitioners. A large body of work exists that describes different influences on business compliance, but a fundamental challenge remains: how to measure compliance or noncompliance behavior itself? Without proper measurement, it's impossible to evaluate existing management and regulatory enforcement practices. Measuring Compliance provides the first comprehensive overview of different approaches that are or could be used to measure compliance by business organizations. The book addresses the strengths and weaknesses of various methods and offers both academics and practitioners guidance on which measures are best for different purposes. In addition to understanding the importance of measuring compliance and its potential negative effects in a variety of contexts, readers will learn how to collect data to answer different questions in the compliance domain, and how to offer suggestio

Laws and norms that focus on women's lives in conflict have proliferated across the regimes of international humanitarian law, international criminal law, international human rights law and the United Nations Security Council. While separate institutions, with differing powers of monitoring and enforcement, implement these laws and norms, the activities of regimes overlap. Women's Rights in Armed Conflict under International Law is the first book to account for this pluralism and institutional diversity. This book identifies key aspects of how different regimes regulate women's rights in conflict, and how they interact. Using country case studies to reveal the practical implications of the fragmented protection of women's rights in conflict, this book offers a dynamic account of how regimes and institutions interact, the extent to which they reinforce each other, and the tensions and gaps in regulation that emerge.

The Work of Politics advances a new understanding of how democratic social movements work with welfare institutions to challenge structures of domination. Klein develops a novel theory that depicts welfare institutions as “worldly mediators,” or sites of democratic world-making fostering political empowerment and participation within the context of capitalist economic forces. Drawing on the writings of Weber, Arendt, and Habermas, and historical episodes that range from the workers' movement in Bismarck's Germany to post-war Swedish feminism, this book challenges us to rethink the distribution of power in society, as well as the fundamental concerns of democratic theory. Ranging across political theory and intellectual history, The Work of Politics provides a vital contribution to contemporary thinking about the future of the welfare state.

Go back to the thrilling time of warring knights who were prepared to give their life in order to protect their lord and his castle. Castles may conjure up a romantic fairy tale world; however, in real life, during the Middle Ages, castles were fortresses, providing shelter and protection for the lord as well as for the peasants who lived on his land. For an army, a lord depended on young soldiers in armor called knights who spent years at the castle learning the skills of warfare. Author Sarah Fabiny dives into the history of castles and how they grew from simple wood structures to mighty fortresses in stone. She also explains who could become a knight and what their lives were like off of the battlefield, enjoying feasts, courting their lady loves, and showing off in tournaments. With 80 fun black-and-white illustrations and an engaging 16-page photo insert, readers will be excited to read this latest addition to Who HQ!

The New York Times bestselling author of The Unhoneymooners returns with an effervescent, "emotional...and surprising" (Shondaland) novel about what happens when two people with everything on the line are thrown together by science--or is it fate? Perfect for fans of The Rosie Project and One Plus One.

Jess holds her loved ones close but working constantly to stay afloat is hard...and lonely. But then Jess hears about GeneticAlly, a buzzy new DNA-based matchmaking company that's predicted to change dating forever. Finding a soulmate through DNA? The reliability o

Fills a great void in Canadian political history by investigating the impact of the often-overlooked figure of Louis St-Laurent. Much of Canada's modern identity emerged from the innovative social policies and ambitious foreign policy of Louis St-Laurent's government. His extraordinarily creative administration made decisions that still resonate today: on health care, pensions, and housing; on infrastructure and intergovernmental issues; and, further afield, in developing Canada's global middle-power role and resolving the Suez Crisis. Yet St-Laurent remains an enigmatic figure.The contributors to The Unexpected Louis St-Laurent were challenged to assess the personal role of the prime minister in these affairs. To what degree did he set the policy agenda? What was his approach to government structures and the substance of policy? They come to varying conclusions about the features of St-Laurent's personality that made him effective (or sometimes less so), about the changes he wrought
