    Evaluación de las inteligencias múltiples en los aprendizajes de los estudiantes de tercer grado, de la escuela Cerro Pelado del Distrito de Ñurün, comarca Ngäbe Bugle. Esta investigación tuvo como objetivo principal determinar mediante evaluación, los niveles de inteligencias múltiples en los aprendizajes de los estudiantes de tercer grado. Y se realizó mediante la aplicación de un instrumento, a docentes que brindaron la información de lo que los estudiantes manejan y saben de cada tipo de inteligencia. La investigación es de tipo cualitativa, se contó con la participación de dos docentes de tercer grado. Además, se consideraron dos variables que funcionaron como bases para buscar estudios similares: las inteligencias múltiples y los aprendizajes de los estudiantes con sus definiciones: conceptual y operacional. Se encontraron evidencias claras ya que, mediante la evaluación, se expusieron los ocho tipos de inteligencia múltiple, cada una con sus diversas capacidades de aprendizaje, en donde las docentes encuestadas pudieron indicar que siempre y casi siempre los estudiantes han demostrado que pueden realizar dichas actividades saben y conocen habilidades en cada una de ellas. Las inteligencias múltiples llevadas a evaluación fueron las propuestas por Gardner (8 inteligencias), y que, en tercer grado, aunque los estudiantes no las puedan identificar con el nombre propio, pueden interactuar con ellas en diversas formas que las docentes les enseñen. Además, son elementos que, de una u otra manera, ayudan en gran medida a los alumnos, ya que a pesar de la posición en que se encuentra ubicada la escuela, en particular Cerro Pelado, las inteligencias múltiples se enseñan con estrategias y transmiten aprendizajes necesarios para todos

    Update on atmospheric neutrinos

    Get PDF
    We discuss the impact of recent experimental results on the determination of atmospheric neutrino oscillation parameters. We use all published results on atmospheric neutrinos, including the preliminary large statistics data of Super-Kamiokande. We reanalyze the data in terms of both vμ → vτ and vμ → ve channels using new improved calculations of the atmospheric neutrino flux. We compare the sensitivity attained in atmospheric neutrino experiments with those of accelerator and reactor neutrino oscillation searches, including the recent CHOOZ experiment. We briefly comment on the implications of atmospheric neutrino data in relation to future searches for neutrino oscillations with long baselines, such as the K2K, MINOS, ICARUS, and NOE experiments.MC is obtained by folding a prediction for the atmospheric neutrino flux with the properties of every individual detector through a Monte Carlo ~MC! procedure. Apart from studying the impact of the new data, our motivation for the present reanalysis of atmospheric neutrino data is theoretical. In this regard, we first of all include the results of a recent calculation of the atmospheric neutrino fluxes as a function of zenith angles @11#, including the muon polarization effect @12#. Moreover, we develop an independent procedure for the comparison of results from different experiments. We demonstrate that our theoretical calculation of the energy distribution of the event rates is in good agreement with the MC expectations. The comparison of the experimental results presented below thus reflects the significance of the atmospheric neutrino anomaly and provides evidence for neutrino oscillations. In this paper we analyze the impact of recent experimental results on atmospheric neutrinos from Super-Kamiokande and Soudan2 on the determinations of atmospheric neutrin

    Diagnostic Procedure for Inter-Sector Relationships in the Model of Municipal Development

    Get PDF
    Several methods were applied to design a new diagnostic procedure of inter-sector relationships, and the coordination between development strategies and key economic sectors within the strategic planning system in the municipality of Nuevitas, province of Camaguey, Cuba. The methods included analysis-synthesis; systemic, to conceive the character of component relationships; interview, survey, and documentary research. They made possible the characterization of the current situation in the municipality. The diagnostic revealed that the analysis of inter-sector relationships is not usually made, due to ongoing deficiencies regarding a procedure design to perform situational strategic diagnostics. According to the results achieved, insufficiencies in inter-sector relationships among the institutions selected for the study were identified, as a reflection of the poor coordination among the sectors. Potentialities and restrictions, weaknesses, strengths, and opportunities were revealed, which called for the implementation of a diagnostic of inter-sector relationships in the area of development strategies. The methodological proposal rests on the supposition that diagnostics should establish methods to include analysis of horizontal relationships among the sectors, convergence with the local development strategy, and more efficiency of integrated development programs.                Several methods were applied to design a new diagnostic procedure of inter-sector relationships, and the coordination between development strategies and key economic sectors within the strategic planning system in the municipality of Nuevitas, province of Camaguey, Cuba.

    Anomalous quartic gauge boson couplings at hadron colliders

    We analyze the potential of the Fermilab Tevatron and CERN Large Hadron Collider (LHC) to study anomalous quartic vector--boson interactions (photon photon Z Z) and (photon photon W+ W-). Working in the framework of SU(2)_L X U(1)_Y chiral Lagrangians, we study the production of photons pairs accompanied by (e+e-), (e nu), and jet pairs to impose bounds on these new couplings, taking into account the unitarity constraints. We compare our findings with the indirect limits coming from precision electroweak measurements as well as with presently available direct searches at LEPII. We show that the Tevatron Run II can provide limits on these quartic limits which are of the same order of magnitude as the existing bounds from LEPII searches. LHC will be able to tighten considerably the direct constraints on these possible new interactions, leading to more stringent limits than the presently available indirect ones

    Constraining anomalous Higgs boson interactions

    The recently announced Higgs boson discovery marks the dawn of the direct probing of the electroweak symmetry breaking sector. Sorting out the dynamics responsible for electroweak symmetry breaking now requires probing the Higgs boson interactions and searching for additional states connected to this sector. In this work, we analyze the constraints on Higgs boson couplings to the standard model gauge bosons using the available data from Tevatron and LHC. We work in a model-independent framework expressing the departure of the Higgs boson couplings to gauge bosons by dimension-six operators. This allows for independent modifications of its couplings to gluons, photons, and weak gauge bosons while still preserving the Standard Model (SM) gauge invariance. Our results indicate that best overall agreement with data is obtained if the cross section of Higgs boson production via gluon fusion is suppressed with respect to its SM value and the Higgs boson branching ratio into two photons is enhanced, while keeping the production and decays associated to couplings to weak gauge bosons close to their SM prediction

    Robust determination of the Higgs couplings: Power to the data

    Get PDF
    We study the indirect effects of new physics on the phenomenology of the recently discovered "Higgs-like" particle. In a model-independent framework these effects can be parametrized in terms of an effective Lagrangian at the electroweak scale. In a theory in which the S U ( 2 ) L × U ( 1 ) Y gauge symmetry is linearly realized they appear at lowest order as dimension-six operators, containing all the standard model fields including the light scalar doublet, with unknown coefficients. We discuss the choice of operator basis which allows us to make better use of all the available data to determine the coefficients of the new operators. We illustrate our present knowledge of those by performing a global five-parameter fit to the existing data which allows simultaneous determination of the Higgs couplings to gluons, electroweak gauge bosons, bottom quarks, and tau leptons. We find that for all scenarios considered the standard model predictions for each individual Higgs coupling and observable are within the corresponding 90% C.L. allowed range, the only exception being the Higgs branching ratio into two photons for the scenario with standard couplings of the Higgs to fermions. We finish by commenting on the implications of the results for unitarity of processes at higher energies

    Determining Triple Gauge Boson Couplings from Higgs Data

    Get PDF
    In the framework of effective Lagrangians with the S U ( 2 ) L × U ( 1 ) Y symmetry linearly realized, modifications of the couplings of the Higgs field to the electroweak gauge bosons are related to anomalous triple gauge couplings (TGCs). Here, we show that the analysis of the latest Higgs boson production data at the LHC and Tevatron give rise to strong bounds on TGCs that are complementary to those from direct TGC analysis. We present the constraints on TGCs obtained by combining all available data on direct TGC studies and on Higgs production analysis

    Deciphering the spin of new resonances in Higgsless models

    We study the potential of the CERN large hadron collider to probe the spin of new massive vector boson resonances predicted by Higgsless models. We consider its production via weak boson fusion which relies only on the coupling between the new resonances and the weak gauge bosons. We show that the large hadron collider will be able to unravel the spin of the particles associated with the partial restoration of unitarity in vector boson scattering for integrated luminosities of 150 - 560     fb − 1 , depending on the new state mass and on the method used in the analyses

    The gauge-Higgs legacy of the LHC Run I

    Get PDF
    The effective Lagrangian expansion provides a framework to study effects of new physics at the electroweak scale. To make full use of LHC data in constraining higher-dimensional operators we need to include both the Higgs and the electroweak gauge sector in our study. We first present an analysis of the relevant di-boson production LHC results to update constraints on triple gauge boson couplings. Our bounds are several times stronger than those obtained from LEP data. Next, we show how in combination with Higgs measurements the triple gauge vertices lead to a significant improvement in the entire set of operators, including operators describing Higgs couplings
