    The purpose of this research is to explore the relation between students’ connectedness to nature, academic major type and learning style. This study categorized student’s academic major into whether it was oriented toward business/advertising or natural resources/agriculture. Understanding students’ relationship with nature is important in a world that faces many environmental challenges. Studying academic major type and learning style provides references for chosen career paths and how students learn most efficiently. By running correlational analyses of these variables, more is understood about how connectedness to nature plays a role in students’ academic choices and learning preferences. Results showed a significant correlation between students’ score on the Nature Relatedness Scale and Academic Major Type. In particular, students orientated toward natural resources and agriculture displayed significantly higher scores on the Nature Relatedness Scale than those orientated toward business and advertising. This suggests that connectedness to nature is an indicator of how students assemble within the university. Future studies should look more thoroughly at connectedness to nature on the broad spectrum of academic majors

    Date de l'opération : 1991 (SD) Inventeur(s) : Richard-Millet Laure-Anne La découverte de mobilier archéologique en 1965 lors de travaux d'adduction d'eau, avait conduit à une rapide fouille de sauvetage indiquant la présence d'un habitat du Néolithique final. Une campagne de sondages a été réalisée en 1991 afin de retrouver l'emplacement du site. Sur quinze sondages ouverts, deux ont révélé du mobilier archéologique. Les vestiges très frais prouvent qu'ils n'avaient pas été déplacés. Le sond..

    Les campagnes de fouilles des années 1960 et 1970 avaient permis de mettre en évidence, sous les couches gallo-romaines, grâce à la présence de tessons de céramique, des niveaux du Néolithique et de l’âge du Bronze (Soubrier, Marquet 1979). Le mobilier a été revu récemment par Roland Irribarria (Inrap) et Anne Hauzeur (Paléotime) qui en ont confirmé le grand intérêt et l’âge néolithique moyen I. Nous avons pu d’autre part avoir accès au mobilier non tourné néolithique et protohistorique prove..

    Le site de Bergeresse à Abilly se trouve en rive droite de la Creuse, sur le versant est de la vallée, à quelques centaines de mètres en contrebas des formations d’altération du Turonien supérieur, livrant les dalles de silex exploitées au Néolithique final pour la fabrication des grandes lames sur livres de beurre. La fouille d’ateliers de débitage du silex a porté sur une surface de plus de 9 000 m2, dont 1 400 m2 ont été fouillés manuellement au cours de 7 campagnes de fouille programmée d..

    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

    Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

    Get PDF
    A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

    Measurement of nuclear modification factors of gamma(1S)), gamma(2S), and gamma(3S) mesons in PbPb collisions at root s(NN)=5.02 TeV

    Get PDF
    The cross sections for ϒ(1S), ϒ(2S), and ϒ(3S) production in lead-lead (PbPb) and proton-proton (pp) collisions at √sNN = 5.02 TeV have been measured using the CMS detector at the LHC. The nuclear modification factors, RAA, derived from the PbPb-to-pp ratio of yields for each state, are studied as functions of meson rapidity and transverse momentum, as well as PbPb collision centrality. The yields of all three states are found to be significantly suppressed, and compatible with a sequential ordering of the suppression, RAA(ϒ(1S)) > RAA(ϒ(2S)) > RAA(ϒ(3S)). The suppression of ϒ(1S) is larger than that seen at √sNN = 2.76 TeV, although the two are compatible within uncertainties. The upper limit on the RAA of ϒ(3S) integrated over pT, rapidity and centrality is 0.096 at 95% confidence level, which is the strongest suppression observed for a quarkonium state in heavy ion collisions to date. © 2019 The Author(s).

    Electroweak production of two jets in association with a Z boson in proton-proton collisions root s =13 TeV

    Get PDF
    A measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at root s = 13 TeV is presented, based on data recorded in 2016 by the CMS experiment at the LHC corresponding to an integrated luminosity of 35.9 fb(-1). The measurement is performed in the lljj final state with l including electrons and muons, and the jets j corresponding to the quarks produced in the hard interaction. The measured cross section in a kinematic region defined by invariant masses m(ll) > 50 GeV, m(jj) > 120 GeV, and transverse momenta P-Tj > 25 GeV is sigma(EW) (lljj) = 534 +/- 20 (stat) fb (syst) fb, in agreement with leading-order standard model predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. No evidence is found and limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are -2.6 <cwww/Lambda(2) <2.6 TeV-2 and -8.4 <cw/Lambda(2) <10.1 TeV-2. The additional jet activity of events in a signal-enriched region is also studied, and the measurements are in agreement with predictions.Peer reviewe
