The 50 Best Albums of 2016 The Montclair, N.J. group Pinegrove have two logos: one, a small box intersected with an identical box, is favored among their legions of young and tattooed fans, as evidenced in an endless stream of RTs on the band’s page. The other is an ampersand. This summer, when Pitchfork interviewed the band’s frontman, Evan Stephens Hall—a 27-year-old of highly enthusiastic, bookish charisma—he said he’d thought about publishing a pamphlet on Pinegrove iconography. Both symbols, he said, are intended to reflect an ethos of multiplicity, of many simultaneous realities, and thus of radical empathy. On Cardinal, Hall’s plainspoken lyrics belie this epistemological headiness, but you can feel the compassion in their raw alt-country arrangements, in phrases that reach and erupt.

Earthquakes in the Himalaya are bigger than in the Alps because tectonic plates collide faster Earthquakes that happen in densely populated mountainous regions, such as the Himalaya, spell bigger earthquakes because of a fast tectonic-plate collision, according to a new study in Earth and Planetary Science Letters. Researchers from Geophysical Fluid Dynamics — ETH Zürich in Switzerland, say their findings give people a more complete view of the risk of earthquakes in mountainous regions. The new study shows that the frequency and magnitude of large earthquakes in the densely populated regions close to mountain chains — such as the Alps, Apennines, Himalaya and Zagros — depend on the collision rate of the smaller tectonic plates. In 2015, a magnitude 7.8 earthquake struck Gorkha-Nepal, and a year later, Norcia, Italy suffered a magnitude 6.2 earthquake. Previous research has attempted to explain the physical causes of earthquakes like these, but with ambiguous results. There are seven large tectonic plates and several smaller ones in the earth’s lithosphere — its outermost layers.
Différence entre didactique et pédagogie La didactique et la pédagogie s'intéressent aux mêmes acteurs : le savoir comme objet d'étude et le couple professeur et élèves. Toutefois, elles se distinguent entre elles par les objets étudiés. La didactique se préoccupe des questions touchant l'acte d'enseigner qui relève des disciplines et se distingue par sa nature épistémologique (nature des connaissances à enseigner). la pédagogie renvoie à la conduite d'une classe, c'est-à-dire aux aspects éducatifs et relationnels qui seraient déterminants pour la progression de l'apprentissage de l'apprenant. Develay (1996) a résumé la distinction entre didactique et pédagogie comme suit : « Certes pédagogie et didactique s'intéressent toutes les deux aux processus d'acquisition (en se centrant sur l'élève) et de la transmission (en se centrant sur l'enseignement) des connaissances. Nous l'avons vu, le didacticien est un spécialiste de l'enseignement de sa discipline.

Jared & The Mill: Western Expansion (Self-released)US: 17 Sep 2013UK: 17 Sep 2013 All signs indicate the nouveau folk renaissance isn’t losing steam anytime soon, with new bands joining in the fray at an exponential level. Of course, the inherent challenge of any upcoming group is to assert their individuality and present what it is about them that warrants more attention than is received by the rest, and this is especially true in a lucrative and popular genre. The Phoenix sextet Jared & The Mill manages to be one of those outfits to stamp their distinctiveness, employing and expanding upon previously understated textures in Americana folk. Now, on first listen of the group’s debut LP, Western Expansion, the comparisons to trendsetters Mumford & Sons is almost a requisite — the abundance of the banjo, the earnest vocals, the rollicking melodies and jaunty rhythms. A stylistic shift occurs with subsequent track “Returning Half”, wherein a western guitar arises in a dirty, electric sweep. Western Expansion Rating:
Earthquake early warning in Mexico reminds California what it still lacks The massive earthquake that ripped through Mexico is offering stark testimony on the power of modern early warning systems that, to the dismay of seismologists who have spent years pushing the technology, do not exist in California or anyplace in the United States. Experts believe the growing death toll from Thursday’s 8.1-magnitude quake off Mexico’s southern coast could have been worse if alarms had not gone off throughout faraway population centers well before the shaking started. The temblor, which struck just before midnight, knocked down buildings and caused skyscrapers to sway hundreds of miles away in Mexico City, but television newscasters, businesses and utility companies there got as much as 92 seconds to warn people and take other steps to protect them. Some experts on Friday posed a question: Why does Mexico have an early warning system while the richest country in the world does not?
L’évolution de l’éducation à la sexualité dans les établissements scolaires 1L’éducation à la sexualité est une composante de la construction de la personne et de l’éducation du citoyen. A ce titre, l’école envisage une éducation à la sexualité dont l’objectif est de permettre aux élèves d’adopter des attitudes de responsabilité individuelle et sociale. La loi no 2001-588 du 4 juillet 2001 relative à l’interruption volontaire de grossesse et à la contraception rend obligatoire une information et une éducation sexuelles dans les écoles, les collèges et les lycées à raison d’au moins trois séances annuelles. La démarche de cette éducation ne laisse aucune ambiguïté. 2Toutefois, cette éducation à la sexualité, si elle est aujourd’hui incontournable et obligatoire, ne va pas de soi et soulève parfois des polémiques se heurtant souvent à des difficultés (Lelièvre, Lec, 2005). 3La sexualité, en effet, n’est pas un domaine comme les autres. 4Les objectifs de cet article sont pluriels. 18 Les années 80 sont marquées par l’apparition du Sida.
Pascaline On your bike: how muscles respond to exercise We all know that exercise makes us fitter and healthier – but what changes take place in our cells to make this happen? Next time you are working out in the gym, or pounding the streets running or jogging, ponder this: the idea of ‘muscle memory’ – that today’s exercise has effects on our muscles years from now – has never been demonstrated scientifically. Does it really exist, and if so, how does it work? These are some of the questions we hope to answer in our on-going research, which aims to pin down the changes that occur in muscles when we exercise, and how our muscles ‘know’ to respond differently to, say, endurance training as opposed to strength training. Helping us to investigate these questions is a large team of volunteers. Not only must they cycle to exhaustion in our gym, but before and after a strenuous exercise regime lasting several weeks, we take a tiny sample of their leg muscle under local anaesthetic (figure 1).

The UN Has Called This The Second Biggest Environmental Problem Facing Our World Is it worth poisoning people to collect some gold? That’s the question now facing Romania’s Prime Minister Mihai Tudose as he contemplates reopening the Rosia Montana goldfield. Rosia Montana holds 314 tons of gold and so offers the prospect of making millions and creating short-term employment opportunities for thousands of workers. But what it also offers the possibility of environmental destruction. A mining project like this would use a process called cyanide amalgamation to extract gold, and this process has left devastation in its wake before, according to an article by Stephen Tuffnell, associate professor of modern US history at the University of Oxford. In the 1970s, a copper mine in Rosia Montana caused the evacuation of the village of Geamana when its land was needed as a storage space for the mine’s cyanide-contaminated waste.
