Anti-poverty researchers and policymakers often wrestle with a basic problem: How can they get people to participate in beneficial programs? Now a new empirical study co-authored by two MIT development economists shows how much more popular such programs can be when socially well-connected citizens are the first to know about them.
Each of us hopes to prepare for what's coming, to improve our fate in the years ahead. This may be humanity's most distinctive trait, explaining our mastery over the world. But the task is muddied by life's essential competitiveness. We need knowledge to hold others accountable, yet each of us worries that others know too much about us...Is it so hard to envisage that tomorrow's citizens -- our children -- may rise to fresh challenges, as we have done?
Though some teachers are still adamantly holding onto traditional formal lectures, many others are considering whether this is an ineffective and outdated model that no longer works in the information age.
Plant breeding largely depends on phenotypic selection in plots and only for some, often disease-resistance-related traits, uses genetic markers. The more recently developed concept of genomic selection, using a black box approach with no need of prior knowledge about the effect or function of individual markers, has also been proposed as a great opportunity for plant breeding. Several empirical and theoretical studies have focused on the possibility to implement this as a novel molecular method across various species. Although we do not question the potential of genomic selection in general, in this Opinion, we emphasize that genomic selection approaches from dairy cattle breeding cannot be easily applied to complex plant breeding.
... At the summit, Mr. Gates told the audience that he sees enormous potential for MOOCs but cautioned that online education still faces many challenges. He also talked briefly about online education during an question-and-answer session with the audience...
One goal of researchers in neuroscience, psychology, and artificial intelligence is to build theoretical models that are able to explain the flexibility and adaptiveness of biological systems. How to build a brain provides a detailed guided exploration of a new cognitive architecture that takes biological detail seriously, while addressing cognitive phenomena. The Semantic Pointer Architecture (SPA) introduced in this book provides a set of tools for constructing a wide range of biologically constrained perceptual, cognitive, and motor models.
Examples of such models are provided, and they are shown to explain a wide range of data including single cell recordings, neural population activity, reaction times, error rates, choice behavior, and fMRI signals. Each of these models introduces a major feature of biological cognition addressed in the book, including semantics, syntax, control, learning, and memory. These models are not introduced as independent considerations of brain function, but instead integrated to give rise to what is currently the world's largest functional brain model.
The last half of this book compares the Semantic Pointer Architecture with the current state-of-the-art, addressing issues of theory construction in the behavioral sciences, semantic compositionality, and scalability, among other considerations. The book concludes with a discussion of conceptual challenges raised by this architecture, and identifies several outstanding challenges for this, and other, cognitive architectures.
So, is the Google era empowering us to be better, smarter, more agile thinkers? Or devolving us into distracted, manic scatterbrains? Is technology-improved discourse going to turn us all into avid, participatory problem solvers? Or will the Web’s centrifugal effects spin us all into little islands of shared conviction — midget Nuremberg rallies — where facts become irrelevant and any opinion can be a memic god? The truth lies somewhere between "Google is making us stupid" and "the Internet will liberate humanity....
Chez Lefort et fils, à Villemandeur, commerce physique et « e-commerce » vont de pair. Le site cuisineaddict.com lancé en 2009 par Pierrick LEFORT (ESSCA 2003) et son associé, Mathias CORBIN est un vrai succès.
Digital literacy has become one of the major issues facing educators in this early part of the 21st century. The need to develop students and teachers digital literacies has become increasingly accepted as fact and yet most teachers' and students' understanding of what exactly constitutes a digital literacy still seems to remain quite vague. Even more vague seems to be teachers' understanding of how precisely we go about developing those literacies.
"The Ewe people of Togo, Africa, have a proverb: “Wisdom is like a baobab tree; no one individual can embrace it.” The proverb refers to the massive trees of the genus Adansonia that can live thousands of years, reach 30 meters into the sky and achieve trunk diameters of 10 meters or more."
