Download or read book Approaches to Algebra written by N. Bednarz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Greek geometry, there is an arithmetic of magnitudes in which, in terms of numbers, only integers are involved. This theory of measure is limited to exact measure. Operations on magnitudes cannot be actually numerically calculated, except if those magnitudes are exactly measured by a certain unit. The theory of proportions does not have access to such operations. It cannot be seen as an "arithmetic" of ratios. Even if Euclidean geometry is done in a highly theoretical context, its axioms are essentially semantic. This is contrary to Mahoney's second characteristic. This cannot be said of the theory of proportions, which is less semantic. Only synthetic proofs are considered rigorous in Greek geometry. Arithmetic reasoning is also synthetic, going from the known to the unknown. Finally, analysis is an approach to geometrical problems that has some algebraic characteristics and involves a method for solving problems that is different from the arithmetical approach. 3. GEOMETRIC PROOFS OF ALGEBRAIC RULES Until the second half of the 19th century, Euclid's Elements was considered a model of a mathematical theory. This may be one reason why geometry was used by algebraists as a tool to demonstrate the accuracy of rules otherwise given as numerical algorithms. It may also be that geometry was one way to represent general reasoning without involving specific magnitudes. To go a bit deeper into this, here are three geometric proofs of algebraic rules, the frrst by Al-Khwarizmi, the other two by Cardano.

Download or read book Trouble in the Making written by Mary Hallward-Driemeier and published by World Bank Publications. This book was released on 2017-10-12 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technology and globalization are threatening manufacturing’s traditional ability to deliver both productivity and jobs at a large scale for unskilled workers. Concerns about widening inequality within and across countries are raising questions about whether interventions are needed and how effective they could be. Trouble in the Making? The Future of Manufacturing-Led Development addresses three questions: - How has the global manufacturing landscape changed and why does this matter for development opportunities? - How are emerging trends in technology and globalization likely to shape the feasibility and desirability of manufacturing-led development in the future? - If low wages are going to be less important in defining competitiveness, how can less industrialized countries make the most of new opportunities that shifting technologies and globalization patterns may bring? The book examines the impacts of new technologies (i.e., the Internet of Things, 3-D printing, and advanced robotics), rising international competition, and increased servicification on manufacturing productivity and employment. The aim is to inform policy choices for countries currently producing and for those seeking to enter new manufacturing markets. Increased polarization is a risk, but the book analyzes ways to go beyond focusing on potential disruptions to position workers, firms, and locations for new opportunities. www.worldbank.org/futureofmanufacturing

Download or read book Making Politics Work for Development written by World Bank and published by World Bank Publications. This book was released on 2016-07-14 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Governments fail to provide the public goods needed for development when its leaders knowingly and deliberately ignore sound technical advice or are unable to follow it, despite the best of intentions, because of political constraints. This report focuses on two forces—citizen engagement and transparency—that hold the key to solving government failures by shaping how political markets function. Citizens are not only queueing at voting booths, but are also taking to the streets and using diverse media to pressure, sanction and select the leaders who wield power within government, including by entering as contenders for leadership. This political engagement can function in highly nuanced ways within the same formal institutional context and across the political spectrum, from autocracies to democracies. Unhealthy political engagement, when leaders are selected and sanctioned on the basis of their provision of private benefits rather than public goods, gives rise to government failures. The solutions to these failures lie in fostering healthy political engagement within any institutional context, and not in circumventing or suppressing it. Transparency, which is citizen access to publicly available information about the actions of those in government, and the consequences of these actions, can play a crucial role by nourishing political engagement.

Download or read book A Roadmap to Reducing Child Poverty written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-09-16 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: The strengths and abilities children develop from infancy through adolescence are crucial for their physical, emotional, and cognitive growth, which in turn help them to achieve success in school and to become responsible, economically self-sufficient, and healthy adults. Capable, responsible, and healthy adults are clearly the foundation of a well-functioning and prosperous society, yet America's future is not as secure as it could be because millions of American children live in families with incomes below the poverty line. A wealth of evidence suggests that a lack of adequate economic resources for families with children compromises these children's ability to grow and achieve adult success, hurting them and the broader society. A Roadmap to Reducing Child Poverty reviews the research on linkages between child poverty and child well-being, and analyzes the poverty-reducing effects of major assistance programs directed at children and families. This report also provides policy and program recommendations for reducing the number of children living in poverty in the United States by half within 10 years.

Download or read book The Promise of Adolescence written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-07-26 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adolescenceâ€"beginning with the onset of puberty and ending in the mid-20sâ€"is a critical period of development during which key areas of the brain mature and develop. These changes in brain structure, function, and connectivity mark adolescence as a period of opportunity to discover new vistas, to form relationships with peers and adults, and to explore one's developing identity. It is also a period of resilience that can ameliorate childhood setbacks and set the stage for a thriving trajectory over the life course. Because adolescents comprise nearly one-fourth of the entire U.S. population, the nation needs policies and practices that will better leverage these developmental opportunities to harness the promise of adolescenceâ€"rather than focusing myopically on containing its risks. This report examines the neurobiological and socio-behavioral science of adolescent development and outlines how this knowledge can be applied, both to promote adolescent well-being, resilience, and development, and to rectify structural barriers and inequalities in opportunity, enabling all adolescents to flourish.

Download or read book The Long Shadow of Informality written by Franziska Ohnsorge and published by World Bank Publications. This book was released on 2022-02-09 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large percentage of workers and firms operate in the informal economy, outside the line of sight of governments in emerging market and developing economies. This may hold back the recovery in these economies from the deep recessions caused by the COVID-19 pandemic--unless governments adopt a broad set of policies to address the challenges of widespread informality. This study is the first comprehensive analysis of the extent of informality and its implications for a durable economic recovery and for long-term development. It finds that pervasive informality is associated with significantly weaker economic outcomes--including lower government resources to combat recessions, lower per capita incomes, greater poverty, less financial development, and weaker investment and productivity.

Download or read book Why Nations Fail written by Daron Acemoglu and published by Currency. This book was released on 2013-09-17 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brilliant and engagingly written, Why Nations Fail answers the question that has stumped the experts for centuries: Why are some nations rich and others poor, divided by wealth and poverty, health and sickness, food and famine? Is it culture, the weather, geography? Perhaps ignorance of what the right policies are? Simply, no. None of these factors is either definitive or destiny. Otherwise, how to explain why Botswana has become one of the fastest growing countries in the world, while other African nations, such as Zimbabwe, the Congo, and Sierra Leone, are mired in poverty and violence? Daron Acemoglu and James Robinson conclusively show that it is man-made political and economic institutions that underlie economic success (or lack of it). Korea, to take just one of their fascinating examples, is a remarkably homogeneous nation, yet the people of North Korea are among the poorest on earth while their brothers and sisters in South Korea are among the richest. The south forged a society that created incentives, rewarded innovation, and allowed everyone to participate in economic opportunities. The economic success thus spurred was sustained because the government became accountable and responsive to citizens and the great mass of people. Sadly, the people of the north have endured decades of famine, political repression, and very different economic institutions—with no end in sight. The differences between the Koreas is due to the politics that created these completely different institutional trajectories. Based on fifteen years of original research Acemoglu and Robinson marshall extraordinary historical evidence from the Roman Empire, the Mayan city-states, medieval Venice, the Soviet Union, Latin America, England, Europe, the United States, and Africa to build a new theory of political economy with great relevance for the big questions of today, including: - China has built an authoritarian growth machine. Will it continue to grow at such high speed and overwhelm the West? - Are America’s best days behind it? Are we moving from a virtuous circle in which efforts by elites to aggrandize power are resisted to a vicious one that enriches and empowers a small minority? - What is the most effective way to help move billions of people from the rut of poverty to prosperity? More philanthropy from the wealthy nations of the West? Or learning the hard-won lessons of Acemoglu and Robinson’s breakthrough ideas on the interplay between inclusive political and economic institutions? Why Nations Fail will change the way you look at—and understand—the world.

Download or read book Building State Capability written by Matt Andrews and published by Oxford University Press. This book was released on 2017 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Governments play a major role in the development process, and constantly introduce reforms and policies to achieve developmental objectives. Many of these interventions have limited impact, however; schools get built but children don't learn, IT systems are introduced but not used, plans are written but not implemented. These achievement deficiencies reveal gaps in capabilities, and weaknesses in the process of building state capability. This book addresses these weaknesses and gaps. It starts by providing evidence of the capability shortfalls that currently exist in many countries, showing that many governments lack basic capacities even after decades of reforms and capacity building efforts. The book then analyses this evidence, identifying capability traps that hold many governments back - particularly related to isomorphic mimicry (where governments copy best practice solutions from other countries that make them look more capable even if they are not more capable) and premature load bearing (where governments adopt new mechanisms that they cannot actually make work, given weak extant capacities). The book then describes a process that governments can use to escape these capability traps. Called PDIA (problem driven iterative adaptation), this process empowers people working in governments to find and fit solutions to the problems they face. The discussion about this process is structured in a practical manner so that readers can actually apply tools and ideas to the capability challenges they face in their own contexts. These applications will help readers devise policies and reforms that have more impact than those of the past.

Download or read book The Origins and Development of Problem Behavior Theory written by Richard Jessor and published by Springer. This book was released on 2016-09-14 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, the first in a series of collected works, traces the evolution of Problem Behavior Theory from its inception to its current status as a widely used framework for understanding and addressing risky behavior in youth and young adults. The theory is explored from its beginnings as a study of deviant behavior and alcohol abuse in a tri-ethnic community through its expansion to include psychosocial aspects of development, risk and protective factors, and health behavior in the larger societal context of youth behavior. In its current form, Problem Behavior Theory constitutes an interdisciplinary approach to research personal and societal factors that are involved in both normative and problematic behavior. Chapters highlight the many contributions of the theory to social science and its potential for informing evidence-based intervention and prevention programs for youth and young adults. Topics featured in this book include: The Tri-Ethnic Community Study. The Socialization of Problem Behavior in Youth Study. The Young Adult Follow-up Study. The problem behavior syndrome. The cross-national generality of Problem Behavior Theory. Problem Behavior Theory and adolescent pro-social behavior. The Origins and Development of Problem Behavior Theory is a must-have resource for researchers/professors, clinicians, and related professionals as well as graduate students in social and developmental psychology, criminology/criminal justice, public health, social work, and related disciplines.

Download or read book Populism and Higher Education Curriculum Development Problem Based Learning as a Mitigating Response written by Romeo V. Turcan and published by Springer Nature. This book was released on 2020-11-21 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Against a background of increasing inequality and a rising tide of nationalism and populism, this book raises concerns that curriculum is being shaped by powerful non-academic, non-accountable forces and that populism – and its manifestations – represent a grave challenge to learning. It explores the extent to which curriculum and learning methods in higher education should respond to this challenge. Using problem based learning as a case study it draws on crossdisciplinary studies to examine how regional, national and organizational perspectives emphasize different aspects of PBL. It questions whether PBL provides an effective response to external influences and a ‘populist’ highereducation agenda. In conclusion the book poses an uncomfortable question whether graduates reflect the external forces shaping curriculum and hence may be as vulnerable to populist rhetoric as non-graduates precisely because the curriculum and learning methods do not engage with the challenges. This book will appeal to scholars of problem based learning, as well as populism and therole of higher education in society.

Download or read book Why We Lie About Aid written by Pablo Yanguas and published by Zed Books Ltd.. This book was released on 2018-02-15 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foreign aid is about charity. International development is about technical fixes. At least that is what we, as donor publics, are constantly told. The result is a highly dysfunctional aid system which mistakes short-term results for long-term transformation and gets attacked across the political spectrum, with the right claiming we spend too much, and the left that we don't spend enough. The reality, as Yanguas argues in this highly provocative book, is that aid isn't – or at least shouldn't be – about levels of spending, nor interventions shackled to vague notions of ‘accountability’ and ‘ownership’. Instead, a different approach is possible, one that acknowledges aid as being about struggle, about taking sides, about politics. It is an approach that has been quietly applied by innovative development practitioners around the world, providing political coverage for local reformers to open up spaces for change. Drawing on a variety of convention-defying stories from a variety of countries – from Britain to the US, Sierra Leone to Honduras – Yanguas provides an eye-opening account of what we really mean when we talk about aid.
