Les réseaux sociaux sont à la mode, mais ils ont toujours existé, et les mathématiques s’y intéressent depuis quelques années déjà… Mais peut-on utiliser la théorie des réseaux pour examiner des rapports sociaux très anciens, et, en allant plus loin encore, concernant des univers au moins partiellement imaginaires ? Et que peut-on en tirer ?

Automation is eliminating the need for people in many jobs. We’ve survived such changes before, but this time it might be different: are we facing a future of stagnant income and worsening inequality? (...) The machines created at Kiva and Rethink have been cleverly designed and built to work with people, taking over the tasks that the humans often don’t want to do or aren’t especially good at. They are specifically designed to enhance these workers’ productivity. And it’s hard to see how even these increasingly sophisticated robots will replace humans in most manufacturing and industrial jobs anytime soon. But clerical and some professional jobs could be more vulnerable. That’s because the marriage of artificial intelligence and big data is beginning to give machines a more humanlike ability to reason and to solve many new types of problems."

Collecting and analyzing information from simple cell phones can provide surprising insights into how people move about and behave—and even help us understand the spread of diseases. At a computer in her office at the Harvard School of Public Health in Boston, epidemiologist Caroline Buckee points to a dot on a map of Kenya’s western highlands, representing one of the nation’s thousands of cell-phone towers. In the fight against malaria, Buckee explains, the data transmitted from this tower near the town of Kericho has been epidemiological gold. When she and her colleagues studied the data, she found that people making calls or sending text messages originating at the Kericho tower were making 16 times more trips away from the area than the regional average. What’s more, they were three times more likely to visit a region northeast of Lake Victoria that records from the health ministry identified as a malaria hot spot. The tower’s signal radius thus covered a significant waypoint for transmission of malaria, which can jump from human to human via mosquitoes. Satellite images revealed the likely culprit: a busy tea plantation that was probably full of migrant workers. The implication was clear, Buckee says. “There will be a ton of infected [people] there.”

"Bonjour à tous J’ai attendu pour ouvrir ce premier billet car je voulais, après plusieurs années de suivi des environnements socio-numériques mettre en évidence combien il sera de plus en plus utile aujourd’hui de préserver son identité. En effet, à l’heure ou nos réputations peuvent se faire et se défaire en un instant par mégarde, par méconnaissance des réseaux, voire encore par l’entrée et l’appartenance à des réseaux on a l’impression que toutes les interactions sur la toile et leurs impacts sur notre vie réelle restent trop souvent encore méconnues..."

Medical centers are testing new, friendly ways to reduce the need for office visits by extending their reach into patients’ homes. - Most patients who enter the gym of the San Mateo Medical Center in California are there to work with physical therapists. But a few who had knee replacements are being coached by a digital avatar instead. The avatar, Molly, interviews them in Spanish or English about the levels of pain they feel as a video guides them through exercises, while the 3-D cameras of a Kinect device measure their movements. Because it’s a pilot project, Paul Carlisle, the director of rehabilitation services, looks on. But the ultimate goal is for the routine to be done from a patient’s home. “It would change our whole model,” says Carlisle, who is running the trial as the public hospital looks for creative ways to extend the reach of its overtaxed budget and staff. “We don’t want to replace therapists. But in some ways, it does replace the need to have them there all the time.”
Receiving remote medical care is becoming more common as technologies improve and health records get digitized. Sense.ly, the California startup running the trial, is one of more than 500 companies using health-care tools from Nuance, a company that develops speech-recognition and virtual-assistant software. “Our goal is basically to capture the patient’s state of mind and body,” says Ivana Schnur, cofounder of Sense.ly and a clinical psychologist who has spent years developing virtual-reality tools in medicine and mental health.

A maverick neuroscientist believes he has deciphered the code by which the brain forms long-term memories.
Bayesian Methods for Hackers is designed as a introduction to Bayesian inference from a computational/understanding-first, and mathematics-second, point of view. Of course as an introductory book, we can only leave it at that: an introductory book. For the mathematically trained, they may cure the curiosity this text generates with other texts designed with mathematical analysis in mind. For the enthusiast with less mathematical-background, or one who is not interested in the mathematics but simply the practice of Bayesian methods, this text should be sufficient and entertaining.

Agent Analyst: Agent-Based Modeling in ArcGIS is an introduction to agent-based modeling using an open-source software called Agent Analyst, which is compatible with ArcGIS software. This workbook’s step-by-step exercises, written by agent-based modeling experts, demonstrate how to create agent-based models using points, polygons, rasters, and representative networks. Key topics include creating, manipulating, and scheduling actions and fields. The book shows how to implement basic-to-complex decision making by agents, and demonstrates the code to capture these decisions. Agent Analyst: Agent-Based Modeling in ArcGIS includes exercises, case studies, and code necessary to begin building agent-based models in ArcGIS Desktop 10. You can download Agent Analyst: Agent-Based Modeling in ArcGIS by clicking the link below.
