The ALife conferences are the major meeting of the artificial life research community since 1987. For its 15th edition in 2016, it was held in Latin America for the first time, in the Mayan Riviera, Mexico, from July 4 -8. The special them of the conference: How can the synthetic study of living systems contribute to societies: scientifically, technically, and culturally? The goal of the conference theme is to better understand societies with the purpose of using this understanding for a more efficient management and development of social systems.
The narrowing of diversity in crop species contributing to the world’s food supplies has been considered a potential threat to food security. However, changes in this diversity have not been quantified globally. We assess trends over the past 50 y in the richness, abundance, and composition of crop species in national food supplies worldwide. Over this period, national per capita food supplies expanded in total quantities of food calories, protein, fat, and weight, with increased proportions of those quantities sourcing from energy-dense foods. At the same time the number of measured crop commodities contributing to national food supplies increased, the relative contribution of these commodities within these supplies became more even, and the dominance of the most significant commodities decreased. As a consequence, national food supplies worldwide became more similar in composition, correlated particularly with an increased supply of a number of globally important cereal and oil crops, and a decline of other cereal, oil, and starchy root species. The increase in homogeneity worldwide portends the establishment of a global standard food supply, which is relatively species-rich in regard to measured crops at the national level, but species-poor globally. These changes in food supplies heighten interdependence among countries in regard to availability and access to these food sources and the genetic resources supporting their production, and give further urgency to nutrition development priorities aimed at bolstering food security.

Recent advances suggest that the concept of information might hold the key to unravelling the mystery of life's nature and origin. Fresh insights from a broad and authoritative range of articulate and respected experts focus on the transition from matter to life, and hence reconcile the deep conceptual schism between the way we describe physical and biological systems. A unique cross-disciplinary perspective, drawing on expertise from philosophy, biology, chemistry, physics, and cognitive and social sciences, provides a new way to look at the deepest questions of our existence. This book addresses the role of information in life, and how it can make a difference to what we know about the world. Students, researchers, and all those interested in what life is and how it began will gain insights into the nature of life and its origins that touch on nearly every domain of science. Hardcover: 514 pages; ISBN-10: 1107150531; ISBN-13: 978-1107150539;
This book considers a relatively new metric in complex systems, transfer entropy, derived from a series of measurements, usually a time series. After a qualitative introduction and a chapter that explains the key ideas from statistics required to understand the text, the authors then present information theory and transfer entropy in depth. A key feature of the approach is the authors' work to show the relationship between information flow and complexity. The later chapters demonstrate information transfer in canonical systems, and applications, for example in neuroscience and in finance. The book will be of value to advanced undergraduate and graduate students and researchers in the areas of computer science, neuroscience, physics, and engineering.

Next month, two seminal image-sharing communities, FFFFOUND! and MLKSHK, will close their doors within a week of each other. There's a profound difference in how they're doing it as noted by someone who's previously sold off a community.
This is a great little piece comparing and contrasting how to relatively similar online communities and social silos are shutting down their services. One is going a much better route than the other and providing export tools and archive ability to preserve the years of work and effort.
The legendary editor who founded the Washington Monthly and pioneered explanatory journalism trains his keen, principled eye on the changes that have reshaped American politics and civic life beginning with the New Deal. “We Do Our Part” was the slogan of Franklin Delano Roosevelt’s National Recovery Administration—and it captured the can-do spirit that allowed America to survive the Great Depression and win World War II. Although the intervening decades have seen their share of progress as well, in some ways we have regressed as a nation. Over the course of a sixty-year career as a Washington, D.C., journalist, historian, and challenger of conventional wisdom, Charles Peters has witnessed these drastic changes firsthand. This stirring book explains how we can consolidate the gains we have made while recapturing the generous spirit we have lost. In a volume spanning the decades, Peters compares the flood of talented, original thinkers who flowed into the nation’s capital to join FDR’s administration with the tide of self-serving government staffers who left to exploit their opportunities on Wall Street and as lobbyists from the 1970s to today. During the same period, the economic divide between rich and poor grew, as we shifted from a culture of generosity to one of personal aggrandizement. With the wisdom of a prophet, Peters connects these two trends by showing how this money-fueled elitism has diminished our trust in one another and our nation—and changed Washington for the worse. While Peters condemns the crass buckraking that afflicts our capital, and the rampant consumerism that fuels our greed, he refuses to see America’s downward drift as permanent. By reminding us of our vanished civic ideal, We Do Our Part also points the way forward. Peter argues that if we want to revive the ethos of the New Deal era—a time when government attracted the brightest and the most dedicated, and when our laws reflected a spirit of humility and community—we need only demand it of ourselves and our elected officials. With a new administration in Washington, the time is ripe for a reassessment of our national priorities. We Do Our Part offers a vital road map of where we have been and where we are going, drawn from the invaluable perspective of a man who has seen America’s better days and still believes in the promise that lies ahead.

It’s a culinary catalyst, an agent of change, a gastronomic rock star. Ubiquitous in the world’s most fabulous cuisines, butter is boss. Here, it finally gets its due. After traveling across three continents to stalk the modern story of butter, award-winning food writer and former pastry chef Elaine Khosrova serves up a story as rich, textured, and culturally relevant as butter itself. From its humble agrarian origins to its present-day artisanal glory, butter has a fascinating story to tell, and Khosrova is the perfect person to tell it. With tales about the ancient butter bogs of Ireland, the pleasure dairies of France, and the sacred butter sculptures of Tibet, Khosrova details butter’s role in history, politics, economics, nutrition, and even spirituality and art. Readers will also find the essential collection of core butter recipes, including beurre manié, croissants, pâte brisée, and the only buttercream frosting anyone will ever need, as well as practical how-tos for making various types of butter at home--or shopping for the best.
In the early 1840s the American West, though claimed by the United States, was considered by many white Americans to be untamed, wild, and possibly rife with unknown wealth. This was a West that existed largely in the American imagination. In fact, the area west of the Missouri was home to complex Native societies, was divided into political structures, and was intimately known, if not formally mapped. These two competing Wests - that imagined by many Americans and that inhabited by Souix, Pawnee, Snake and Nez Pierce tribes - were mapped both geographically and textually by John C. Frémont between 1842 and 1843. Frémont set out from St. Louis in the summer of 1842, and began to chronicle his journey west, in the wake of "emigrants" who were moving to the Oregon Territory - a route known as the "Oregon Trail." Frémont's first expedition covered the land between the Missouri River and the Rocky Mountains during the summer and fall of 1842. In the summer of 1843 he set out to write an account of the second half of the Oregon Trail, from the Rocky Mountains to the Columbia River in Oregon. The maps contained here are drawn from the Library of Congress's collection "Topographical map of the road from Missouri to Oregon, commencing at the mouth of the Kansas in the Missouri River and ending at the mouth of the Walla-Wallah in the Columbia." They were created using Frémont's journal, and cover his first and second expeditions. I have annotated the maps with accounts of the resting places, flora, fauna, and people Frémont's and his party encountered on their journey west.
You’ve played the game Oregon Trail via DOS (as a child), online, or via app but have you traced the actual trail taken by John C. Frémont between 1842 and 1843? Now you can with this daily interactive map with journal.

Linkrot and the lack of permanence on the web is a recurring theme for this blog. In the final days as App.net was winding down, I wanted to put my money where my mouth was. I spun up a couple new servers and wrote a set of scripts to essentially download every post on App.net. It feels like a fragile archive, put together hastily, but I believe it’s mostly complete. I’ve also downloaded thumbnail versions of some of the public photos hosted on App.net.
Some personal thoughts and opinions on what ``good quality mathematics'' is, and whether one should try to define this term rigorously. As a case study, the story of Szemer\'edi's theorem is presented.
This looks like a cool little paper.
Some thoughts after reading
And indeed it was. The opening has lovely long (though possibly incomplete) list of aspects of good mathematics toward which mathematicians should strive. The second section contains an interesting example which looks at the history of a theorem and it’s effect on several different areas. To me most of the value is in thinking about the first several pages. I highly recommend this to all young budding mathematicians.
In particular, as a society, we need to be careful of early students in elementary and high school as well as college as the pedagogy of mathematics at these lower levels tends to weed out potential mathematicians of many of these stripes. Students often get discouraged from pursuing mathematics because it’s “too hard” often because they don’t have the right resources or support. These students, may in fact be those who add to the well-roundedness of the subject which help to push it forward.
I believe that this diverse and multifaceted nature of “good mathematics” is very healthy for mathematics as a whole, as it it allows us to pursue many different approaches to the subject, and exploit many different types of mathematical talent, towards our common goal of greater mathematical progress and understanding. While each one of the above attributes is generally accepted to be a desirable trait to have in mathematics, it can become detrimental to a field to pursue only one or two of them at the expense of all the others.
As I look at his list of scenarios, it also reminds me of how areas within the humanities can become quickly stymied. The trouble in some of those areas of study is that they’re not as rigorously underpinned, as systematic, or as brutally clear as mathematics can be, so the fact that they’ve become stuck may not be noticed until a dreadfully much later date. These facts also make it much easier and clearer in some of these fields to notice the true stars.
As a reminder for later, I’ll include these scenarios about research fields:
Syndicated copies to:
- A field which becomes increasingly ornate and baroque, in which individual
results are generalised and refined for their own sake, but the subject as a
whole drifts aimlessly without any definite direction or sense of progress;
- A field which becomes filled with many astounding conjectures, but with no
hope of rigorous progress on any of them;
- A field which now consists primarily of using ad hoc methods to solve a collection
of unrelated problems, which have no unifying theme, connections, or purpose;
- A field which has become overly dry and theoretical, continually recasting and
unifying previous results in increasingly technical formal frameworks, but not
generating any exciting new breakthroughs as a consequence; or
- A field which reveres classical results, and continually presents shorter, simpler,
and more elegant proofs of these results, but which does not generate any truly
original and new results beyond the classical literature.
This book offers a broad introduction to food policies in the United States. Real-world controversies and debates motivate the book’s attention to economic principles, policy analysis, nutrition science and contemporary data sources. It assumes that the reader's concern is not just the economic interests of farmers, but also includes nutrition, sustainable agriculture, the environment and food security. The book’s goal is to make US food policy more comprehensible to those inside and outside the agri-food sector whose interests and aspirations have been ignored.
The chapters cover US agriculture, food production and the environment, international agricultural trade, food and beverage manufacturing, food retail and restaurants, food safety, dietary guidance, food labeling, advertising and federal food assistance programs for the poor.
The author is an agricultural economist with many years of experience in the non-profit advocacy sector, the US Department of Agriculture and as a professor at Tufts University. The author's well-known blog on US food policy provides a forum for discussion and debate of the issues set out in the book.

In How to Have a Good Day, economist and former McKinsey partner Caroline Webb shows readers how to use recent findings from behavioral economics, psychology, and neuroscience to transform our approach to everyday working life.
Advances in these behavioral sciences are giving us ever better understanding of how our brains work, why we make the choices we do, and what it takes for us to be at our best. But it has not always been easy to see how to apply these insights in the real world – until now.
In How to Have a Good Day, Webb explains exactly how to apply this science to our daily tasks and routines. She translates three big scientific ideas into step-by-step guidance that shows us how to set better priorities, make our time go further, ace every interaction, be our smartest selves, strengthen our personal impact, be resilient to setbacks, and boost our energy and enjoyment. Through it all, Webb teaches us how to navigate the typical challenges of modern workplaces—from conflict with colleagues to dull meetings and overflowing inboxes—with skill and ease.
Filled with stories of people who have used Webb’s insights to boost their job satisfaction and performance at work, How to Have a Good Day is the book so many people wanted when they finished Nudge, Blink and Thinking Fast and Slow and were looking for practical ways to apply this fascinating science to their own lives and careers.
A remarkable and much-needed book, How to Have a Good Day gives us the tools we need to have a lifetime of good days.
