World Population Policies Their Origin, Evolution, and Impact


Free Download World Population Policies: Their Origin, Evolution, and Impact By John F. May (auth.)
2012 | 340 Pages | ISBN: 9400728360 | PDF | 3 MB
This book examines the history behind the formulation, implementation, and evaluation of population policies in the more developed, the less developed, and the least developed countries from 1950 until today, as well as their future prospects. It links population policies with the theories of the demographic, epidemiological, and migratory transitions. It begins by summarizing the demographic situation around the world, with an emphasis on population policies and their underlying theories. Then, it reviews the early efforts to reduce mortality and fertility in the developing countries. This is followed by a description of the internationalization of the debate on population issues and the transformation of these programs into more formal population policies, particularly in the developing countries. The book reviews also the situation of the developed countries and their specific challenges – sub-replacement fertility, population aging, and immigration – and examines the effectiveness of population policies. It also explores the way forward and future prospects for population policies over the next decades. The book provides numerous concrete examples from all over the world, and show how population policies are actually implemented and what have been their successes as well as their constraints. Above all, the book highlights the importance of understanding underlying demographic trends when assessing the development prospects of any country.The book is recommended for not only demographers, social scientists, and policymakers but also economists and political scientists who are interested in social and demographic change around the world. Demography students and researchers who are interested in applying knowledge on population trends and prospects in designing and evaluating public policies will find this an invaluable reference work.

Alpha Sequence, The Electromagnetic Origin Of The Strong And Weak Nuclear Forces


Free Download Alpha Sequence, The: Electromagnetic Origin Of The Strong And Weak Nuclear Forces by Malcolm H Mac Gregor
English | June 10, 2022 | ISBN: 9811252327 | 156 pages | MOBI | 10 Mb
This book is centered on a surprising Tevatron and LHC experimental result, the accurate equality of gauge boson and top quark energy Ew + Ez = Et. The ramifications of this unanticipated result extend down to the lower energies, and lead to two new elementary particle paradigms. The first is the use of energies E rather than masses m for analysing particle excitation patterns, where E =mc2. The second is the recognition that ground-state particle energies are generated in the form of quantized energy packets that are produced in "α-boost" energy excitations, where α-1 ~137 is the fine structure constant. Repeated α-boosts form a "reservoir" of energy packets, which merge and reproduce the quantized energies of the various particle and quark ground-state configurations. An α-generated energy excitation path extends upward from the electron to the top quark t. The steps in this path, which contain two α-boosts, combine coherently to give the energy equation Eelectron x 18/α2 = Et, which is accurate to 0.3%. A branching energy path reproduces the energy of the bottom quark b to 0.1%. Particle energies and lifetimes are conjugate quantities, and the α-quantized particle energies are reflected in α-quantized particle mean lifetimes, as revealed by lifetime Descriptions on a logarithmic α-spaced grid. The accurate factor-of-137 spacings between the classical electron radius, Compton radius, and Bohr orbit radius suggest introducing both a radial and a mass dependence into α, which leads to an equation for the transformation of Coulomb energy into electron non-electromagnetic mass. The electron spin and magnetic moment are reproduced by a Compton-sized relativistically spinning sphere (RSS). The anomalous electron magnetic moment is also accounted for by the RSS, in response to Richard Feynman’s 1961 Challenge to provide such an explanation. The mathematics used here is straightforward, and the calculations are guided by fits to the elementary particle RPP energy and lifetime data bases, which are provided here in Appendices A and B.

The Historical Origin of the African Economic Crisis From Colonialism to China


Free Download Alemayehu Geda, "The Historical Origin of the African Economic Crisis: From Colonialism to China"
English | ISBN: 1527526305 | 2019 | 180 pages | PDF | 2 MB
This book illuminates the answers to various major questions on African development related to international trade and finance. It explores the economic interaction between Africa and the now-developed countries (the West) in the past and China today, as well as the legacy of these interactions for Africas growth and poverty reduction effort today. In addition, it discusses the implication of this legacy for Africas future development, and considers whether lessons can be drawn from this experience in terms of the continents future development? By providing in-depth historical and economic analysis conducted in non-technical terms, the book represents a valuable resource for policy makers, researchers, and students, as well as international organizations that focus on African development.

The Amazing Unity of the Universe And Its Origin in the Big Bang


Free Download The Amazing Unity of the Universe: And Its Origin in the Big Bang by Edward van den Heuvel
English | PDF (True) | 2016 | 317 Pages | ISBN : 3319235427 | 19.4 MB
In the first chapters the author describes how our knowledge of the position of Earth in space and time has developed, thanks to the work of many generations of astronomers and physicists. He discusses how our position in the Galaxy was discovered, and how in 1929, Hubble uncovered the fact that the Universe is expanding, leading to the picture of the Big Bang. He then explains how astronomers have found that the laws of physics that were discovered here on Earth and in the Solar System (the laws of mechanics, gravity, atomic physics, electromagnetism, etc.) are valid throughout the Universe. This is illustrated by the fact that all matter in the Universe consists of atoms of the same chemical elements that we know on Earth. This unity is all the more surprising when one realizes that in the original Big Bang theory, different parts of the Universe could never have communicated with each other. It then is a mystery how they could have shared the same physical laws. This problem was solved by the introduction of the idea of inflation, a phase of extremely rapid expansion of the Universe during the first fraction of a second following the Big Bang. The author explains how the unity of the Universe finds its origin in the Big Bang prior to inflation. The book addresses the many fundamental questions about the Universe and its contents from the perspective of the Big Bang: the formation of structure in the Universe, the questions of the mysterious dark matter and dark energy, the possibilities of other Universes (the Multiverse) and of the existence of intelligent life elsewhere in the Universe.

The Enigma of the Origin of Portolan Charts A Geodetic Analysis of the Hypothesis of a Medieval Origin


Free Download The Enigma of the Origin of Portolan Charts: A Geodetic Analysis of the Hypothesis of a Medieval Origin by Roel Nicolai
English | 2016 | ISBN: 9004282971 | 572 pages | PDF | 23 Mb
The sudden appearance of portolan charts, realistic nautical charts of the Mediterranean and Black Sea, at the end of the thirteenth century is one of the most significant occurrences in the history of cartography. Using geodetic and statistical analysis techniques these charts are shown to be mosaics of partial charts that are considerably more accurate than has been assumed. Their accuracy exceeds medieval mapping capabilities. These sub-charts show a remarkably good agreement with the Mercator map projection. It is demonstrated that this map projection can only have been an intentional feature of the charts’ construction. Through geodetic analysis the author eliminates the possibility that the charts are original products of a medieval Mediterranean nautical culture, which until now they have been widely believed to be.
