This textbook provides a thorough coverage of classical mechanics. Meant for undergraduate and graduate physics students, it contains discussions on topics beneficial for researchers also. Along with standard graduate-level topics, it highlights and demonstrates the applications of classical mechanics in various areas of physics, astronomy, and astrophysics, thus emphasizing the subject's relevance to current research. Detailed explanations are provided throughout to support self-study and ensure clear understanding of concepts. The text begins with preliminary topics and then proceeds to Lagrange's equation of motion, Hamilton's principle of stationary action, and conservation principles in classical mechanics. It then extends to topics like Hamiltonian formulation of laws of mechanics, two-body central force problem, and restricted three-body problem, among others. Lagrange and Poisson brackets are discussed in exclusive chapters. The book concludes with expositions on Hamilton–Jacobi formulation of dynamics, perturbation theory in Hamiltonian mechanics, dynamics of rigid bodies, and nonlinear dynamics and chaos.
Offering new readings on language and civil conflict in a variety of Ancient Greek and Roman texts, this study puts these reflections from the classical world in dialogue with contemporary philosophy and political theory. Daniel Sutton focuses on Thucydides, Plato, Sallust, and Tacitus, exploring the ways in which the figure of paradiastole (often termed 'rhetorical redescription') was deployed to explain the conflicts of value which underpinned civil strife. These texts paint vivid pictures of what happens to language during civil discord: pictures which seem increasingly familiar today. Simultaneously, they grapple deeply with what it means to search for timeless values in times of conflict. This study demonstrates how ancient texts can offer us new ways of understanding the role of language in civil discord, of restoring political dialogue in fractious times, and of approaching intellectual history itself.
From the Asvamedha sacrifice to the mounted police, modernist paintings to the medieval cavalry, oceanic trade to urban transport – horses have occupied a prominent position in almost every sphere of human history in South Asia. The Coveted Mount brings a holistic analysis of the compelling history of this human-nonhuman relationship from prehistory to the twenty-first century. The essays in this book unravel the role of the horse in gift exchanges, colonial cities, astrological knowledge, military campaigns, modern art, political culture, religious belief, veterinary sciences, and oceanic commerce. They do so by interpreting colonial records, ancient epics, epigraphic records, medieval coins, temple friezes, modern art, stone and terracotta sculptures, imperial chronicles, equestrian treatises, and wall paintings. In the process, the essays reveal South Asia's historical connections with the world. Overall, this richly illustrated book shows how, when, and why the horse became the coveted mount of South Asian societies
This Element documents the life trajectories of Cambodian English users from rural, low socioeconomic backgrounds, and their experiences with the English language in a variety of contexts. Studies on English in Cambodia have, to date, focused primarily on elite users in urban contexts, largely overlooking the use of English at the grassroots level, such as among the lower and working classes, despite the fact that English has appeared to make inroads across all levels of Cambodian society in recent decades. The stories of individuals whose voices tend to be excluded from mainstream academic discourse are thus featured in this Element, providing a fresh glimpse into the sociolinguistic realities at the Cambodian grassroots – and the significant impact that English has had on the lives of such individuals.
In the 1970s radical economists campaigned to reform their discipline and their universities. They became journalists and activists, moving beyond academia, to forge new models of public engagement and collaborative knowledge in economic life. Radical Expectations tells the story of how these economists set out to make economics more democratic. It traces their campaign to bring protest movements to the campuses, triggering the emergence of an alternative understanding of expertise directed at validating and empowering the perspectives and voices of women, Black Americans, labor activists, and the urban poor. It shows how a radical identity formed and how radicals helped reform disciplinary institutions. Furthermore, it argues that the radical economics' legacy was the development of a language and models of expert–lay collaboration that empowers direct action in economic affairs. The book is about the community of radical economists who championed the promise of change and what came of it.
Brain maldevelopment or injury in utero can cause life-long disability. Focussing on improvements in imaging methods, therapeutics, and perinatal care that can help to identify, prevent, or treat brain problems in the fetus and newborn, this new edition brings the reader fully up to date with recent advances in clinical management and outcome assessment. Updated material includes protective strategies for pre-term and term infants, ways of promoting of brain development in the neonatal intensive care unit, resuscitation, and immediate care after resuscitation (golden hour care), and parental perspectives, particularly strategies for communicating with families. An outstanding international team of highly experienced neonatologists and maternal-fetal medicine clinicians have produced a practical and authoritative clinical text offering clear management advice to all clinicians involved in the treatment of the fetus and newborn.
How do we describe the collective identity of people who make a popular revolution? Notwithstanding marked differences, most accounts understand revolutionary collectives as partisan and relegate spectators to irrelevance-or, worse, to the ignominy of cowards and traitors. Revisiting histories of the 1979 revolution in Iran, Arash Davari explores how millions of people defied expectations and joined popular assemblies to demand the fall of the Pahlavi regime. Through the lens of recent global social movements, Insurgent Witness presents an archetype of collective identity as partisan and spectator at once. Combining novel findings with a fresh methodological approach to previously considered collections, this book presents a distinct concept of revolutionary subjectivity-one that describes the terms of mass revolt in Iran and at the same time challenges prevailing assumptions about social change and popular sovereignty in contemporary political thought.
How do cities shape the planet, and how can we shape cities for a sustainable future? This book explores how urbanization drives global environmental change and how cities function as dynamic ecosystems within the Earth system. Connecting urban ecology, Earth system science and socio-environmental thinking, it provides the knowledge and perspective to understand cities not just as challenges but as critical spaces for innovation and change. From air and water systems to energy flows, biodiversity, and climate impacts, it offers clear frameworks, real-world case studies, and tools for analyzing urban ecosystems and their impacts across scales. Written in accessible language, the book is for both physical and social scientists working in urban ecology, urban planning and sustainability. It will equip advanced students, researchers and professionals with the knowledge and tools to reimagine cities as critical hubs of resilience and sustainable innovation.
Chapter 5 builds on the previous discussion of procurement by analyzing how politicians’ use of career control tools can distort the allocation of public contracts. Through qualitative accounts, it documents how mayors and bureaucrats manipulate bidding processes to ensure that contracts are awarded to firms with partisan ties. Contract-level data reveals striking patterns: despite the geographic proximity of districts, over 80 percent of firms that are awarded contracts operate in just one district. The geographic concentration of contract allocation indicates that entry into procurement markets depends on cultivating ties with local politicians and bureaucrats. The chapter also shows that politicized contracting is especially prevalent in competitive districts and where mayors harbor ambitions for higher office, as these contexts heighten incentives to trade contracts for political support. Survey experiments confirm bureaucrats’ expectations that partisan firms are favored over more experienced but politically neutral competitors. These findings converge to depict procurement as a highly politicized process that undermines efficiency, reduces competition, and ultimately produces lower-quality infrastructure. By linking political ambition, electoral competition, and procurement practices, the chapter illustrates how career control mechanisms translate into the systematic misallocation of public resources.
Chapter 7 reflects on the book’s findings and their broader implications. It underscores that state capacity is not determined solely by formal rules or resources, but by the everyday power relations between politicians and bureaucrats. Investments in infrastructure, personnel, or technology matter, but their effectiveness depends on how politicians and bureaucrats interact. The book highlights the “grey zone” between fully politicized and fully meritocratic systems, arguing that most states fall somewhere in between. Ghana exemplifies this dynamic, but the theory also applies elsewhere. Comparative evidence from India and Indonesia shows similar patterns: politicians exploit career controls to extract loyalty and manipulate bureaucratic action, especially in competitive electoral contexts. These parallels suggest the argument has broad external validity. The chapter also considers how the equilibrium might shift. Reforms that strengthen bureaucratic autonomy, insulate career management, or increase transparency in procurement could reduce partisan manipulation. Yet such reforms are politically difficult, as they challenge the very tools politicians rely on. By situating bureaucratic management at the heart of governance outcomes, the chapter points toward future research on how institutional design can mitigate corruption and enhance equitable service delivery in developing democracies.
This Element brings three topics into closer contact: scepticism about the external world, the metaphysics of perception, and the epistemology of perception. It argues that a certain kind of response to external world scepticism is significantly stronger if we make certain theoretical commitments regarding the metaphysics and epistemology of perception. I argue that a neo-Moorean epistemological disjunctivist response to scepticism is much more compelling when underpinned by a naïve realist theory of perceptual phenomenal character and the transparency model of how we acquire knowledge of our perceptual states. The possibility that these theories are true radically alters the dialectical situation with respect to external world scepticism: the sceptical argument is on much shakier ground than is usually appreciated. Integrating our theorising about our knowledge of the external world and our theorising about the metaphysics and epistemology of perception affords a more comprehensive view of our anti-sceptical options.
Artificial intelligence is reshaping decisions that affect people, institutions, and societies. Understanding how to design, deploy, and govern AI systems that can be trusted is now essential in many disciplines. This book offers a clear, concise introduction to trustworthy AI, treating AI not just as a technical artifact but as a socio-technical system embedded in human contexts. Developed from an internationally applicable educational framework, the book is designed for teaching and learning in computer science, data science, law, policy, business, and related fields. It equips students and professionals with the concepts and judgment needed to engage critically and responsibly with AI in practice. Combining ethics, governance, and practical insight, the book explains key concepts including transparency, fairness, accountability, human oversight, and stakeholder participation. An interdisciplinary approach makes the material accessible to both technical and non-technical audiences, with realistic scenarios and reflection questions so readers connect principles to real-world AI applications.
Most women initially discuss health-related matters with a primary care clinician and can have a plethora of sex-specific medical needs throughout the life course. With greater expectations for GPs and allied health professionals to manage many women's health conditions, this is an invaluable guide for primary care practitioners looking to deliver holistic care to their female patients. This new edition has been thoroughly updated with the most recent guidelines, covering topics such as contraceptive choices, infertility, breast conditions, pregnancy and menopause, along with specific diseases such as ovarian cysts and ovarian cancer. There is a spotlight on the early diagnosis of endometriosis as well as the need for wider menopausal and psychosexual care. Chapters include a list of key points as well as patient cases to illustrate the application of the content. The book is invaluable for primary care clinicians and those preparing for the DRCOG and MRCGP examinations.
The clinical encounter is typically divided into medical interventions for body/ brain and psychotherapeutic interventions for mind/ emotions. In recent years, medical and psychotherapy education have undergone radical pedagogic (negative) transformations – justified on economic grounds. These have resulted in the adoption of a reductive instrumental values focus at the expense of education of deeper values: the historical, ethical, aesthetic, political, and transcendental (meaning). Observable competences displace assessment of potential as capabilities, where an education into professional identity through innovative curriculum design has been reduced to a set of syllabi producing technicians. In turn, this promotes focus on managed curriculum content over emergent process. Transformation in professional education is imperative, where innovative production of metaphor is seen to challenge a dominant reductive literalism. Poetry, embedded within a wider poetic imagination, provides the necessary medium through which a multiple values-based medicine and psychotherapy of quality may be restored.
