Can predictive analytics help banks, consumers avoid overdraft issues? New study says, yes

ScienceDaily Comp&Math - ორშ, 03/12/2018 - 23:08
In 2012, consumers paid $32 billion in overdraft fees, which represented the single largest source of revenue for banks from demand deposit accounts, while leading to significant levels of consumer dissatisfaction and attracting attention from government regulators. In a recent study, researchers have found that it may be possible to help correct this problem through the application of sophisticated data analytics.

LIGO and Virgo announce four new gravitational-wave detections

MIT Top News - ორშ, 03/12/2018 - 23:00
The following news article is adapted from a press release issued by the Laser Interferometer Gravitational-wave Observatory (LIGO) Laboratory, in partnership with the LIGO Scientific Collaboration (LSC) and Virgo Collaboration . LIGO is funded by the National Science Foundation (NSF) and operated by Caltech and MIT, which conceived and built the project. Presently, David Shoemaker, senior research scientist in MIT's Kavli Institute for Astrophysics and Space Research, serves as the elected Spokesperson for the LSC. On Saturday, Dec. 1, scientists attending the Gravitational Wave Physics and Astronomy Workshop in College Park, Maryland, presented new results from the National Science Foundation's LIGO (Laser Interferometer Gravitational-Wave Observatory) and the European-based VIRGO gravitational-wave detector regarding their searches for coalescing cosmic objects, such as pairs of black holes and pairs of neutron stars. The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and one merger of neutron stars, which are the dense, spherical remains of stellar explosions. Six of the black hole merger events had been reported before, while four are newly announced. From Sept. 12, 2015, to Jan. 19, 2016, during the first LIGO observing run since undergoing upgrades in a program called Advanced LIGO, gravitational waves from three binary black hole mergers were detected. The second observing run, which lasted from Nov. 30, 2016 to Aug. 25, 2017, yielded one binary neutron star merger and seven additional binary black hole mergers, including the four new gravitational-wave events being reported now. The new events are known as GW170729, GW170809, GW170818, and GW170823, in reference to the dates they were detected. All of the events are included in a new catalog, also released Saturday, with some of the events breaking records. For instance, the new event GW170729, detected in the second observing run on July 29, 2017, is the most massive and distant gravitational-wave source ever observed. In this coalescence, which happened roughly 5 billion years ago, an equivalent energy of almost five solar masses was converted into gravitational radiation. GW170814 was the first binary black hole merger measured by the three-detector network, and allowed for the first tests of gravitational-wave polarization (analogous to light polarization). The event GW170817, detected three days after GW170814, represented the first time that gravitational waves were ever observed from the merger of a binary neutron star system. What's more, this collision was seen in gravitational waves and light, marking an exciting new chapter in multimessenger astronomy, in which cosmic objects are observed simultaneously in different forms of radiation. One of the new events, GW170818, which was detected by the global network formed by the LIGO and Virgo observatories, was very precisely pinpointed in the sky. The position of the binary black holes, located 2.5 billion light-years from Earth, was identified in the sky with a precision of 39 square degrees. That makes it the next best localized gravitational-wave source after the GW170817 neutron star merger. Caltech’s Albert Lazzarini, deputy director of the LIGO Laboratory, says “The release of four additional binary black hole mergers further informs us of the nature of the population of these binary systems in the universe and better constrains the event rate for these types of events." "In just one year, LIGO and VIRGO working together have dramatically advanced gravitational-wave science, and the rate of discovery suggests the most spectacular findings are yet to come,” says Denise Caldwell, director of NSF's Division of Physics. "The accomplishments of NSF's LIGO and its international partners are a source of pride for the agency, and we expect even greater advances as LIGO's sensitivity becomes better and better in the coming year." "The next observing run, starting in Spring 2019, should yield many more gravitational-wave candidates, and the science the community can accomplish will grow accordingly,” says David Shoemaker, spokesperson for the LIGO Scientific Collaboration and senior research scientist in MIT’s Kavli Institute for Astrophysics and Space Research. “It’s an incredibly exciting time.” “It is gratifying to see the new capabilities that become available through the addition of Advanced Virgo to the global network,” says Jo van den Brand of Nikhef (the Dutch National Institute for Subatomic Physics) and VU University Amsterdam, who is the spokesperson for the Virgo Collaboration. “Our greatly improved pointing precision will allow astronomers to rapidly find any other cosmic messengers emitted by the gravitational-wave sources.” The enhanced pointing capability of the LIGO-Virgo network is made possible by exploiting the time delays of the signal arrival at the different sites and the so-called antenna patterns of the interferometers. “The new catalog is another proof of the exemplary international collaboration of the gravitational wave community and an asset for the forthcoming runs and upgrades” adds EGO Director Stavros Katsanevas. The scientific papers describing these new findings, which are being initially published on the arXiv repository of electronic preprints, present detailed information in the form of a catalog of all the gravitational wave detections and candidate events of the two observing runs as well as describing the characteristics of the merging black hole population. Most notably, we find that almost all black holes formed from stars are lighter than 45 times the mass of the Sun. Thanks to more advanced data processing and better calibration of the instruments, the accuracy of the astrophysical parameters of the previously announced events increased considerably. Laura Cadonati, deputy spokesperson for the LIGO Scientific Collaboration, says “These new discoveries were only made possible through the tireless and carefully coordinated work of the detector commissioners at all three observatories, and the scientists around the world responsible for data quality and cleaning, searching for buried signals, and parameter estimation for each candidate — each a scientific specialty requiring enormous expertise and experience.” LIGO is funded by NSF and operated by Caltech and MIT, which conceived of LIGO and led the Initial and Advanced LIGO projects. Financial support for the Advanced LIGO project was led by the NSF with Germany (Max Planck Society), the U.K. (Science and Technology Facilities Council) and Australia (Australian Research Council-OzGrav) making significant commitments and contributions to the project. More than 1,200 scientists from around the world participate in the effort through the LIGO Scientific Collaboration, which includes the GEO Collaboration. A list of additional partners is available at https://my.ligo.org/census.php . The Virgo collaboration consists of more than 300 physicists and engineers belonging to 28 different European research groups: six from Centre National de la Recherche Scientifique (CNRS) in France; 11 from the Istituto Nazionale di Fisica Nucleare (INFN) in Italy; two in the Netherlands with Nikhef; the MTA Wigner RCP in Hungary; the POLGRAW group in Poland; Spain with IFAE and the Universities of Valencia and Barcelona; two in Belgium with the Universities of Liege and Louvain; Jena University in Germany; and the European Gravitational Observatory (EGO), the laboratory hosting the Virgo detector near Pisa in Italy, funded by CNRS, INFN, and Nikhef.

3Q: Kate Trimble on experiential learning at MIT

MIT Top News - ორშ, 03/12/2018 - 23:00
Kate Trimble officially took the helm of the Office of Experiential Learning (OEL) on Dec. 1, but she is no stranger to the Institute. Trimble has been the associate dean for the Priscilla King Gray (PKG) Public Service Center since 2016, where she focused on energizing and expanding the PKG center's mission of inspiring and preparing MIT students to address complex social and environmental challenges. As the OEL’s new senior associate dean and director, she sees a promising landscape in which she can leverage existing opportunities and expand the office’s mission and impact. MIT News spoke to Trimble about her new leadership role and her vision for experiential learning at MIT. Q: What intrigued you about this role? A: MIT is a remarkable, one-of-a-kind place for experiential learning. Experiential learning — applied, immersive work in real-world settings with real-world stakes and consequences — is everywhere at MIT. It’s happening all over campus: in faculty labs, in Edgerton’s makerspaces, in first-year learning communities like Terrascope, through public service programs at PKG. And it’s happening around the world, through programs like D-Lab and MISTI. It’s just part of the DNA of MIT — "mens et manus." Before they graduate, 91 percent of undergraduates do a UROP, and UROP is just one of the ways that students can be involved in experiential learning. So students are already participating in huge numbers, and when you look at survey data, they really enjoy these experiences and get a lot out of them personally and professionally. When you talk to alumni and ask them about their most transformative experiences as students, often what they point to is an experiential learning opportunity they had. So, what’s really compelling to me personally, and part of why I took this position, is that I think experiential learning is a great way to learn. I think it’s incredibly complimentary to the more traditional educational model, and constructively complicates learning for students. Experiential learning is intense and often messy, but that messiness helps students understand and master the concepts that they’re learning in the lecture hall. Having said that, the experiential learning landscape at MIT is a bit of a jungle, so I’m excited about the challenge of thinking creatively and collaboratively about how to make it easier for students to explore their options and choose programs that help them build the skills and knowledge they’ll need, here at MIT and later in life. Q: Can you say more about that? What would you say the current state-of-the-union is here in terms of experiential learning? A: Although there’s a lot of terrific experiential learning happening at MIT, it’s happening in a fairly disorganized way. When I was applying for the job, I tried to put myself in the shoes of an MIT student who was trying to figure out what to do next summer. There are so many options — whether it’s a UROP, or participating in the solar car team, or doing an internship with an NGO, or taking a class that includes fieldwork abroad. It’s kind of a free-for-all. And while there’s strong word-of-mouth about many of these opportunities, students still have to search through more than a dozen different websites, selection criteria, deadlines, fees or funding, and more to learn about all of the available options. That’s a lot of time that students are investing just to understand what the possibilities are, and we all know that time is something that MIT students don’t have a lot of. When you think about the curriculum, and you think about majors, these are intentionally-designed, well-organized and articulated pathways for students. It’s clear which classes teach certain material or topics, which are prerequisites, what the required or recommended sequence is. But we don’t have an analogous structure for experiential learning — there’s no course catalog or even a central website to easily search through all of the different options and see how they might fit together and relate to what students are learning in their classes. So, I think the state of the union is that there’s an incredible but somewhat overwhelming array of opportunities, and students are currently attacking the problem with typical MIT gusto. They’re choosing their own adventures from all of the great programs on and off campus. But we could do more to help students understand all of their options and make choices with full information. Q: Where do you see other opportunities to make an impact? A: I want to explore how OEL can be a resource for the entire campus. OEL is currently home to five programs and centers [D-Lab, Edgerton Center, Global Education, PKG Center, and UROP], but how do we start to become the place where students, staff, and faculty can find advice on building strong partnerships with community agencies, resources on reflective practice or risk management, or support to incorporate more project- or community-based learning into a class? How can OEL be an effective advocate for experiential learning and create a rising tide that lifts all experiential boats, in a way? We also have the opportunity to start a conversation about how MIT could more intentionally or formally integrate experiential learning into its educational architecture. If you read the recent report from NEET [New Engineering Education Transformation], the emerging leaders in the field have moved project-based learning from the sidelines to the center of their educational models. It’s not an optional or bolt-on activity but a fundamental part of how students learn and how subjects are taught. So, the question is, what would that approach look like at MIT? Is that something that students want? Is that something the faculty want? And if that’s the direction we want to go in, how can OEL help MIT move in that direction? We shouldn’t be prescriptive in terms of what happens or how it happens — why limit the incredible creativity here at MIT? But we can encourage and nurture innovative ideas and programs, while creating new tools and resources to help people do what they already do better, or do more of it.

So, I think the state of the union is that there’s an incredible but somewhat overwhelming array of opportunities, and students are currently attacking the problem with typical MIT gusto. They’re choosing their own adventures from all of the great programs on and off campus. But we could do more to help students understand all of their options and make choices with full information. Q: Where do you see other opportunities to make an impact? A: I want to explore how OEL can be a resource for the entire campus. OEL is currently home to five programs and centers [D-Lab, Edgerton Center, Global Education, PKG Center, and UROP], but how do we start to become the place where students, staff, and faculty can find advice on building strong partnerships with community agencies, resources on reflective practice or risk management, or support to incorporate more project- or community-based learning into a class? How can OEL be an effective advocate for experiential learning and create a rising tide that lifts all experiential boats, in a way? We also have the opportunity to start a conversation about how MIT could more intentionally or formally integrate experiential learning into its educational architecture. If you read the recent report from NEET [New Engineering Education Transformation], the emerging leaders in the field have moved project-based learning from the sidelines to the center of their educational models. It’s not an optional or bolt-on activity but a fundamental part of how students learn and how subjects are taught. So, the question is, what would that approach look like at MIT? Is that something that students want? Is that something the faculty want? And if that’s the direction we want to go in, how can OEL help MIT move in that direction? We shouldn’t be prescriptive in terms of what happens or how it happens — why limit the incredible creativity here at MIT? But we can encourage and nurture innovative ideas and programs, while creating new tools and resources to help people do what they already do better, or do more of it.

COP24 : vers un échec annoncé ?

Yahoo! Actualités: Les titres Sciences - ორშ, 03/12/2018 - 22:57
La ville polonaise de Katowice s'est transformée en capitale mondiale du climat, le temps de la COP24, la Conférence des Nations unies sur les changements climatiques. Plus de 25.000 participants réunis avec comme objectif la mise en œuvre des engagements pris en matière de réduction des gaz à effet de serre. Or pour Antonio Guterres, le secrétaire général de l'ONU, les nations du monde "ne vont pas assez vite" contre le changement climatique. Pour le Professeur polonais Zbigniew Ustrnul,  cette conférence risque à nouveau d'aboutir sur un bilan en demi-teinte :" Il sera peut être difficile de parvenir à un consensus, à un compromis, car cette conférence sur le climat réunit des délégations de différentes régions du monde avec différents niveaux de développement socio-économique." Dans les couloirs de la COP24, on croise également de jeunes participants, venus se battre pour la planète. Greta, 15 ans, vient de Suède : "Tous les vendredis, je manifeste pour le climat devant le Parlement suédois. Nous avons déjà participé à de nombreuses réunions comme celle-ci, mais rien ne s'est concrétisé." Il y a trois ans à Paris, les pays avaient fixé des objectifs de réduction de gaz à effet de serre pour que la hausse des températures sur la planète ne dépasse pas les deux degrés par rapport à l'ère pré-industrielle. Mais pour les ONG, les actions en faveur du climat sont insuffisantes : "De nombreux signaux indiquent que ce sommet n'a pas été bien préparé. Tous les espoirs risquent de ne pas se concrétiser. Nous avons besoin d'une action décisive, nous avons besoin d'ambition. Nous avons besoin que tous les pays qui sont réunis ici agissent contre le changement climatique", souligne Pawel Szypulski de Greenpeace Pologne. "Les pays du monde entier devraient s'éloigner des combustibles fossiles, de la combustion du charbon, du pétrole et du gaz et passer à des sources d'énergies renouvelables. Nous avons déjà la technologie, les innovations se développent et, en fait, tout dépend du seul bon vouloir des États pour mettre tout cela en œuvre", indique pour sa part Joanna Mieszkowicz de Aeris Futuro Foundation. Des personnalités et des débats son attendus durant cette COP24 qui doit s'étendre sur près de deux semaines. De notre correspondant à Katowice, Leszek Kabłak : "Les pays doivent tripler leurs efforts pour atteindre l'objectif de 2°C. S'ils maintiennent le rythme actuel d'émissions, le réchauffement pourrait être d'environ 3 °C d'ici la fin du siècle."

Gilets jaunes: Sortie de crise confuse sur l'île de La Réunion

Alcohol trouble more likely for some never-deployed soldiers

Futurity.org - ორშ, 03/12/2018 - 22:50

US Army Reserve and National Guard soldiers who feel more guilt or other negative emotions about never having been deployed are more likely to misuse alcohol, a new study shows.

“A greater degree of non-deployment emotions—such as guilt, less value, less camaraderie, and less connectedness—was associated with greater frequency and amount of alcohol drinking among never-deployed Army Reserve and National Guard soldiers,” says lead author Rachel Hoopsick, a community health and health behavior PhD candidate in the School of Public Health and Health Professions at the University at Buffalo.

“Male, but not female soldiers, experienced a greater likelihood of alcohol problems when they had highly negative non-deployment emotions,” Hoopsick says.

Reserve service members, who number just over 1 million in the US, have been shown to be at high risk for problems with substance use and mental health. But less is known about the drinking patterns of soldiers who have never been deployed, Hoopsick says.

While previous research hasn’t uncovered any significant differences between recently deployed and never-deployed soldiers in terms of alcohol use, never-deployed service members may be less likely to be considered for targeted screening and intervention efforts as those who have been deployed.

“US Army Reserve and National Guard soldiers are at high risk for alcohol misuse, and our prior work demonstrated that negative emotions…are prevalent among those who have never been deployed,” Hoopsick says.

“Non-deployment emotions are associated with alcohol problems among men and are thus important to consider in the overall health and well-being of never-deployed service members,” she says, adding that they should be included in alcohol screening and prevention efforts.

Researchers say non-deployment may affect men more so than women because of what has previously been called the “reserve soldier identity,” of which deployment is a key component.

In the current study, which appears in Alcoholism: Clinical and Experimental Research, 77 percent of male soldiers and 70 percent of female soldiers experienced some type of negative emotions over their non-deployment.

Among never-deployed soldiers, 23 percent of men and 21 percent of women reported getting drunk at least once per month, while 12 percent of men and 8 percent of women had clinically significant alcohol problems.

“The importance of considering all soldiers and not just those who have deployed is essential for the prevention and intervention of problematic substance use and other issues,” says coauthor Gregory G. Homish, associate professor and associate chair of the community health and health behavior department.

Data for the paper came from Operation: SAFETY (Soldiers and Families Excelling Through the Years), an ongoing study of the health and well-being of US Army Reserve and National Guard soldiers and their partners.

The National Institute on Drug Abuse and the National Center for Advancing Translational Sciences of the National Institutes of Health funded the work.
