An analysis of the loss in performance caused by selfish, uncoordinated behavior in networks.Most of us prefer to commute by the shortest route available, without taking into account the traffic congestion that we cause for others. Many networks, including computer networks, suffer from some type of this "selfish routing." In Selfish Routing and the Price of Anarchy, Tim Roughgarden studies the loss of social welfare caused by selfish, uncoordinated behavior in networks. He quantifies the price of anarchy―the worst-possible loss of social welfare from selfish routing―and also discusses several methods for improving the price of anarchy with centralized control.Roughgarden begins with a relatively nontechnical introduction to selfish routing, describing two important examples that motivate the problems that follow. The first, Pigou's Example, demonstrates that selfish behavior need not generate a socially optimal outcome. The second, the counterintiuitve Braess's Paradox, shows that network improvements can degrade network performance. He then develops techniques for quantifying the price of anarchy (with Pigou's Example playing a central role). Next, he analyzes Braess's Paradox and the computational complexity of detecting it algorithmically, and he describes Stackelberg routing, which improves the price of anarchy using a modest degree of central control. Finally, he defines several open problems that may inspire further research. Roughgarden's work will be of interest not only to researchers and graduate students in theoretical computer science and optimization but also to other computer scientists, as well as to economists, electrical engineers, and mathematicians.

“You let me play once in your garden, to-day you shall come with me to my garden, which is Paradise.” ― Oscar Wilde, The Selfish Giant — A Classic!— Includes Images from the Story

We've needlessly turned parenting into an unpleasant chore. Parents invest more time and money in their kids than ever, but the shocking lesson of twin and adoption research is that upbringing is much less important than genetics in the long run. These revelations have surprising implications for how we parent and how we spend time with our kids. The big lesson: Mold your kids less and enjoy your life more. Your kids will still turn out fine.Selfish Reasons to Have More Kids is a book of practical big ideas. How can parents be happier? What can they change--and what do they need to just accept? Which of their worries can parents safely forget? Above all, what is the right number of kids for you to have? You'll never see kids or parenthood the same way again.

The book is about this beautiful butterfly. Her wings are beautiful like the rainbow, but she does not have friends. Shes so in love with the way her wings have many colors.

A long time has passed since the war act on Cancer declared by former USA president Nixon, almost half a century ago. Today, after so many years of feverish research and uncountable efforts worldwide, the end of the war appears far as ever, whereas the fight is leading researchers to newer and newer battlefronts while frontiers in bioscience are continuously being surpassed. In this scenario, “The Selfish Cell” is a script record of the most important strategic points gathered during these years of war, with the goal to provide solid ground onto which to step ahead for future assaults against this terrible disease. At the same time, it is an attempt to shift the debate on cancer toward a more peaceful and possibly productive semantic terrain, where to reflect with the aid of superior wisdom to finally get out of that terrible chaos of fight and death dominating our days. In this perspective, “The selfish cell” becomes an occasion for reflecting the limits of our human selfishness and their consequences on both our social and natural environment.

Presenting a new approach to understanding evolution, Dawkins asserts that our genes build and maintain us in order to make more genes, instead of thinking about organisms using genes to reproduce themselves. From front flap: "Dawkins draws on everything from game theory to his concept of memes--units of cultural information transmitted from mind to mind--to make his compelling arguments. The Selfish Gene exposes a world of savage competition, ruthless exploitation, and deceit--a genetic drama of fascinating implications."

The perverted king of the seas never ceases to make Kanan cry when making love to him. In the kingdom of the merpeople, what will happen when young Kanan, struggling to express his feelings to his first love, a human boy, is compelled to "get beneath me" by the worst possible man?

Culture is a unique and fascinating aspect of the human species. How did it emerge and how does it develop? Richard Dawkins has suggested that culture evolves and that memes are the cultural replicators, subject to variation and selection in the same way as genes function in the biological world. In this sense human culture is the product of a mindless evolutionary algorithm. Does this imply that we are mere meme machines and that the conscious self is an illusion? Kate Distin extends and strengthens Dawkins's theory and presents a fully developed and workable concept of cultural DNA. She argues that culture's development can be seen both as the result of memetic evolution and as the product of human creativity. Memetic evolution is therefore compatible with the view of humans as conscious and intelligent.

The million copy international bestseller, critically acclaimed and translated into over 25 languages.This 30th anniversary edition includes a new introduction from the author as well as the original prefaces and foreword, and extracts from early reviews. As relevant and influential today as when it was first published, The Selfish Gene has become a classic exposition of evolutionary thought.Professor Dawkins articulates a gene's eye view of evolution - a view giving centre stage to these persistent units of information, and in which organisms can be seen as vehicles for their replication. This imaginative, powerful, and stylistically brilliant work not only brought the insights ofNeo-Darwinism to a wide audience, but galvanized the biology community, generating much debate and stimulating whole new areas of research.

"Lots of yaoi fun."-BuzzScope.com Orito, the president of the Honors Society, won't take no for an answer. He refuses to stop pursuing the affections of Ryuya, the vice president. After all, according to Orito, the vice president is supposed to be his "right hand man." The advances keep escalating, and Ryuya's honor is at stake! Will he remain pure and defiant, or will he give in to Orito's strong and sensuous game of love?

In Selfish Libertarians and Socialist Conservatives?, Nathan W. Schlueter and Nikolai G. Wenzel present a lively debate over the essential questions that divide two competing political philosophies. Wenzel―a libertarian who believes the state should be restricted to protecting life, liberty, and property―and Schlueter―a conservative who thinks the state has a larger role to play in protecting public welfare, safety, and morals―explore the fundamental similarities and differences between their respective positions. Over a series of point-counterpoint chapters, they lay out the essential tenets of their own stances, critiquing the other. This engaging dialogue introduces readers to the foundations of each political philosophy. To vividly illustrate the diverging principles underlying conservatism and libertarianism, the authors explore three different hot-button case studies: marriage, immigration, and education. Compact, accessible, and complete with suggestions for further reading, Selfish Libertarians and Socialist Conservatives? is an ideal teaching tool that places these two political perspectives in fruitful dialogue with one another.

Campus politics aren't the only things on Orito's mind, and Ryuya is shocked to discover that his newfound suitor always gets what he wants. This volume also includes four bonus stories!

This is a new edition of possibly the most exciting and innovative book on evolution in years. An international bestseller, Dawkins's superb reworking of the theory of natural selection has the rare distinction of having provoked as much interest outside the scientific community as within it. Fascinating, convincing, and beautiful in the simplicity with which complex ideas are expressed, The Selfish Gene is a classic. The revised, expanded edition contains two important new chapters. "Nice Guys Finish First" shows how cooperation can evolve even in a basically selfish world, and "The Long Reach of the Gene" advances the startling view that genes may reach outside the bodies in which they sit to manipulate other individuals--and even the world at large. The book concludes with completely new endnotes in which Dawkins replies to previous critics, or elaborates on points in the original text. Written in characteristically lively and accessible style, this new edition confirms Dawkins's reputation as one of the most brilliant biologists of his generation.

While the giant is away, the local children fill his garden with their games and laughter, spilling over the green grass and colorful flowers, perching in the peach trees, and singing with the birds. When the giant returns, he throws them out, declaring that the garden is his and only his to enjoy. Quickly, the garden withers and winter takes hold, only to be broken by the return of a solitary child longing to play in what used to be paradise. The child's sadness melts the giant's heart, and he realizes what a selfish giant he has been. He opens up his garden but must wait a lifetime to once again see the fragile boy who reminded him about generosity and love.
