Galan Christian & Heinrich Patrick (dir.), Being Young in Super-Aging Japan. Formative Events and Cultural Reactions

Comment devenir adulte dans la société la plus « vieille » au monde ? La question pourrait paraître incongrue, elle est au contraire très fructueuse. En s’interrogeant sur les conséquences du vieillissement, non pas sur les individus les plus âgés, mais sur les plus jeunes, l’ouvrage collectif Being Young in Super-Aging Japan. Formative Events and Cultural Reactions livre un regard original sur les défis rencontrés par les jeunes générations japonaises en cette seconde décennie du xxie siècle..

Sociologie comparée des âges et des générations

Cécile Van de Velde, maître de conférences Sociologie des âges de la vie Ce séminaire clôture un cycle de deux ans destiné à proposer une lecture raisonnée et critique de la sociologie des âges de la vie. Celle-ci a longtemps été segmentée en autant de travaux portant sur des âges ciblés ; elle fait preuve d’une effervescence renouvelée, dans la dynamique de débats scientifiques de plus en plus transversaux et internationalisés. Le séminaire s’est attaché à dégager les apports et les limites ..

Sociologie comparée des âges et des générations

Cécile Van de Velde, maître de conférences Politiques publiques et parcours de vie en Europe En amont de la rédaction d’un petit manuel intitulé Sociologie des âges de la vie (Éditions Armand Colin, à paraître), ce séminaire « Politiques publiques et parcours de vie en Europe » a proposé une analyse transversale et comparée des politiques sociales européennes par le prisme de leurs impacts respectifs sur les parcours de vie individuels. La réflexion s’est attachée à unifier des champs d’étude..

Pratiquer l’agriculture en temps de pandémie : sens et reconnaissance au travail des néo-agriculteurs québécois

The current health crisis has, among other things, reopened the debate on the hierarchy of trades, particularly on the so-called "essential" trades. Among them, small organic farmers have been put forward, as the pandemic has revealed the inescapable nature of their trade and, faced with the dependence of globalized markets, the need to relocate Quebec agriculture. By seeking to understand what the pandemic is doing to agriculture, this article gathers the point of view of small-scale organic farmers on their profession in the light of the current crisis, taking care to select those who operate on a small scale and who have made a transition to agriculture as a new lifestyle choice. Between March and November 2020, semi-structured interviews were conducted with 25 farmers who are now market gardeners, livestock farmers, winemakers or maple syrup producers, who, whether or not they are labeled, all practice farming with organic processes. For these producers who, long before the pandemic, saw agriculture as a means of bringing meaning back into their lives, the social mission they give to their work has not been disrupted. Nevertheless, by bringing it to the forefront, the crisis has made it possible to rethink the relationship between agriculture and society.La crise sanitaire actuelle a, entre autres, relancé le débat sur la hiérarchie des corps de métiers, en particulier sur les métiers dits « essentiels ». Parmi eux, les petits agriculteurs biologiques ont été mis de l’avant, la pandémie ayant révélé le caractère incontournable de leur métier et, face à la dépendance des marchés mondialisés, la nécessité de relocaliser l’agriculture québécoise. En cherchant à comprendre ce que la pandémie fait à l’agriculture, cet article recueille le point de vue des « petits » agriculteurs biologiques sur leur métier à l’aune de la crise actuelle, en prenant soin de sélectionner ceux qui opèrent sur petite échelle et qui ont fait une transition vers l’agriculture comme nouveau choix de vie. Entre mars et novembre 2020, des entrevues semi-directives ont été effectuées avec 25 agriculteurs et agricultrices aujourd’hui maraichers, éleveurs, vignerons ou acériculteurs qui, labellisés ou non, pratiquent tous une agriculture avec des procédés biologiques. Pour ces producteurs qui, bien avant la pandémie, ont vu dans l’agriculture le moyen de redonner du sens à leur existence, la mission sociale qu’ils accordent à leur travail n’a pas été bouleversée. Néanmoins, en venant la placer sur le devant de la scène, la crise a permis de repenser les rapports entre cette « petite » agriculture et la société

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
