 Algebraic Semantics of Imperative Programs By Joseph A. Goguen, Grant Malcolm 1996 | 228 Pages | ISBN: 026207172X | DJVU | 2 MB Algebraic Semantics of Imperative Programs presents a self-contained and novel "executable" introduction to formal reasoning about imperative programs. The authors' primary goal is to improve programming ability by improving intuition about what programs mean and how they run.The semantics of imperative programs is specified in a formal, implemented notation, the language OBJ; this makes the semantics highly rigorous yet simple, and provides support for the mechanical verification of program properties.OBJ was designed for algebraic semantics; its declarations introduce symbols for sorts and functions, its statements are equations, and its computations are equational proofs. Thus, an OBJ "program" is an equational theory, and every OBJ computation proves some theorem about such a theory. This means that an OBJ program used for defining the semantics of a program already has a precise mathematical meaning. Moreover, standard techniques for mechanizing equational reasoning can be used for verifying axioms that describe the effect of imperative programs on abstract machines. These axioms can then be used in mechanical proofs of properties of programs.Intended for advanced undergraduates or beginning graduate students, Algebraic Semantics of Imperative Programs contains many examples and exercises in program verification, all of which can be done in OBJ.  Affordable excellence: the Singapore healthcare story By William A. Haseltine 2013 | 196 Pages | ISBN: 0815724160 | PDF | 4 MB Winner of the 2013 Asian Publishing AwardBest Insight into Asian Societies (non-fiction): Excellence AwardThis is the story of the Singapore healthcare system: how it works, how it is financed, its history, where it is going, and what lessons it may hold for national health systems around the world. Singapore ranks sixth in the world in healthcare outcomes, yet spends proportionally less on healthcare than any other high-income country. Singapore achieves its results at less than one-fourth the cost of healthcare in the United States and about half that of Western European countries. This is the first book to set out a comprehensive system-level description of healthcare in Singapore, with a view to understanding what can be learned from Singapore's unique system design and development path.The lessons from Singapore's healthcare system will be of interest to those currently planning the future of healthcare in emerging economies, as well as those engaged in the urgent debates on healthcare in the wealthier countries faced with serious long-term challenges in healthcare financing. Policymakers, legislators, public health officials responsible for healthcare systems planning, finance and operations, as well as those working on healthcare issues in universities and think tanks should understand how the Singapore system works to achieve affordable excellence.  Affective Sexual Pedagogies in Film and Television By Kyra Clarke 2017 | 262 Pages | ISBN: 1317310780 | PDF | 3 MB Popular film and television hold valuable potential for learning about sex and sexuality beyond the information-based model of sex education currently in schools. This book argues that the representation of complicated-or "messy"-relationships in these popular cultural forms makes them potent as affective pedagogical moments. It endeavours to develop new sexual literacies by contemplating how pedagogical moments, that is, fleeting moments which disrupt expectations or create discomfort, might enrich the available discourses of sexuality and gender, especially those available to adolescents. In Part One, Clarke critiques the heteronormative discourses of sex education that produce youth in particularly gendered ways, noting that "rationality" is often expected to govern experiences that are embodied and arguably inherently incoherent. Part Two explores public intimacy, contemplating the often overlapping and confused boundaries between public and private.  Katrina Avila Munichiello, "A Tea Reader: Living Life One Cup at a Time" English | 2017 | ISBN: 0804848998 | 256 pages | EPUB | 3.5 MB A Tea Reader contains a selection of stories that cover the spectrum of life.  Rex Shelley, "A River of Roses" English | 2011 | ISBN: 9814346268 | 472 pages | EPUB | 0.69 MB Meet Philippa Rosario. She s 56 and feisty, a junior college teacher who dabbles in the Chinese zodiac, confident that she has all human nature taped. Enter once again, Vicky Viera, mellowed by a tragic past. Together, they weave the threads of a spell-binding odyssey spanning four generations of the Rosario family from the raging Alfonso and clairvoyant Antonio, to Ignatius, a spirited hormone-driven teenager. In this novel, Rex Shelley introduces a host of memorable multi-hued characters: the cheroot-smoking, wine-swigging padre, the contractor unlucky in love yet ending up with all the aces, the clarinet player whose religion and passions are at odds with each other. The Eurasians of his other novels are also present every one of them firmly bound by the fate that history and the Chinese zodiac have reserved for them.

It predicted that during the first half of the 21st century the ongoing growth in the human ecological footprint would stop-either through catastrophic "overshoot and collapse"-or through well-managed "peak and decline." So, where are we now? And what does our future look like? In the book 2052, Jorgen Randers, one of the coauthors of Limits to Growth, issues a progress report and makes a forecast for the next forty years. To do this, he asked dozens of experts to weigh in with their best predictions on how our economies, energy supplies, natural resources, climate, food, fisheries, militaries, political divisions, cities, psyches, and more will take shape in the coming decades. He then synthesized those scenarios into a global forecast of life as we will most likely know it in the years ahead. The good news: we will see impressive advances in resource efficiency, and an increasing focus on human well-being rather than on per capita income growth. But this change might not come as we expect. Future growth in population and GDP, for instance, will be constrained in surprising ways-by rapid fertility decline as result of increased urbanization, productivity decline as a result of social unrest, and continuing poverty among the poorest 2 billion world citizens. Runaway global warming, too, is likely. So, how do we prepare for the years ahead? With heart, fact, and wisdom, Randers guides us along a realistic path into the future and discusses what readers can do to ensure a better life for themselves and their children during the increasing turmoil of the next forty years. |
