Factores determinantes del desempeño estudiantil en matemáticas en dos instituciones educativas visto desde la calidad educativa

El problema de esta investigación consistió en la trascendencia de los resultados de las pruebas estandarizadas haciendo énfasis en el área de matemáticas, reflejando así la calidad educativa a través de los desempeños matemáticos de los estudiantes; este trabajo tuvo como objetivo principal caracterizar los factores que inciden en el desempeño matemático de los estudiantes y su relación con la calidad educativa en dos instituciones que están en diferente categorización según el ICFES. Este trabajo se direcciona al paradigma empírico analítico de tipo explicativo, el cual según Parker (2011) "afirman que la vida cotidiana es el sitio central de procesos socioculturales e históricos que deben ser objeto de nuestro estudio" esto teniendo en cuenta que el objeto a estudio está basado en situaciones reales que se ven reflejadas en las pruebas estandarizadas. La metodología mixta, será la que nos guíe en el camino de esta investigación ya que según Sampieri (2010) “representa un conjunto de procesos sistemáticos, empíricos y críticos de investigación e implican la recolección y el análisis de datos cuantitativos y cualitativos”. Se realizara un análisis documental, según Quintana (2006), el cual consta de un proceso que consiste en rastrear e inventariar los documentos existentes y disponibles; clasificar los documentos identificados; seleccionar los documentos más pertinentes para los propósitos de la investigación, a fin de construir una síntesis comprensiva total sobre los factores determinantes en el desempeño que intervienen directamente desde la Institución. Los teóricos que guían esta investigación van desde el aspecto de calidad educativa según Aguerrondo y Xifra (2008). Para las autoras, una educación de calidad es aquella que responde de manera adecuada a las demandas de la sociedad y a los intereses de los educandos donde está inmersa; mientras que en rendimiento académico tenemos a Linares (2001) donde clasifica los factores que afectan el rendimiento de los estudiantes que de una u otra manera afectan el rendimiento en matemáticas. De acuerdo con Cuevas (2013) el desempeño escolar se refiere al nivel de aprovechamiento del alumno a partir de los estándares educativos instituidos en una sociedad e implica desde el mínimo hasta el máximo aprovechamiento. Se pudo concluir que de los cuatros factores que determinan la calidad educativa los más importantes son: los factores personales, académicos e Institucionales, ya que estos se relacionan directamente con el buen desempeño de los estudiantes en el área de matemáticas

Viabilidad para la construcción de un hotel campestre en el municipio de Carmen de Apicalá enfocado en el mercado de colegios, empresa pymes y turismo en general

94 páginas : ilustraciones, mapas, planos, gráficos.In order to improve the work environment, organizations have seen the need to create a prevention plan through training, business meetings, etc; thus creating the need to have a place that gives them a space to rest, relax and enjoy nature; This is how the business idea of implementing a country hotel with these characteristics arises. likewise, it happens in educational institutions who schedule trips for their students with the intention of changing their routine and interacting in pleasant spaces. Taking into account the new trend of alternative tourism, and the rapid growth and reception that ecotourism has had, led to study the feasibility of implementing the Hotel Campestre Bello Horizonte, in the municipality of Carmen de Apicala, near Bogota where the target market and its warm climate, is an excellent project that will benefit the business sector, since they can develop there dynamic and spaces for recreation, integration, communication.

Restoration of native Atlantic salmon runs in northern Spain: do costs outweigh benefits?

Atlantic salmon stocks in northern Spain are at the southern range of the species distribution. As such they are likely more vulnerable to environmental change and human disturbance. The Nalon-Narcea River salmon is one such population in Asturias, Spain. The river is dammed throughout the watershed with few fish passage facilities. However, angling data show that salmon returns are consistent although the population is relatively small. We have employed one tributary as a model, the River Trubia. Although some problems of agriculture and industrial pollution have been detected downstream, an upstream habitat evaluation suggests that adequate spawning and juvenile habitat exists. The regional Government has proposed to construct fishways for allowing upstream passage of salmon. This would potentially increase salmon production, but there are also some concerns like increased hybridization of salmon and trout which is already evident downriver and which previous work suggests will increase as salmon colonize new habitat, and potential changes in fishing regulations as salmon distributions shift upriver and away from traditional angling areas. Here, we present an overview of ecological and social aspects of salmon habitat restoration in the River Nalon-Narcea that we hope will provide solutions that balance costs and benefits and may be applicable to other anadromous populations

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb(-1). The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 -dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m(jj) < 760 GeV, the azimuthal angle difference between the two jets and the angular variable chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured b (b) over bar -dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta

Properties of jets measured from tracks in proton-proton collisions at center-of-mass energy sqrt(s) = 7 TeV with the ATLAS detector

Jets are identified and their properties studied in center-of-mass energy sqrt(s) = 7 TeV proton-proton collisions at the Large Hadron Collider using charged particles measured by the ATLAS inner detector. Events are selected using a minimum bias trigger, allowing jets at very low transverse momentum to be observed and their characteristics in the transition to high-momentum fully perturbative jets to be studied. Jets are reconstructed using the anti-k(t) algorithm applied to charged particles with two radius parameter choices, 0.4 and 0.6. An inclusive charged jet transverse momentum cross section measurement from 4 GeV to 100 GeV is shown for four ranges in rapidity extending to 1.9 and corrected to charged particle-level truth jets. The transverse momenta and longitudinal momentum fractions of charged particles within jets are measured, along with the charged particle multiplicity and the particle density as a function of radial distance from the jet axis. Comparison of the data with the theoretical models implemented in existing tunings of Monte Carlo event generators indicates reasonable overall agreement between data and Monte Carlo. These comparisons are sensitive to Monte Carlo parton showering, hadronization, and soft physics models

Gender roles and their implications in intercultural communication process

This literature review, searches for better understanding the implications of gender roles differences when intercultural communication takes place in societies. This research suggests that the differences in male and female communication styles affect and have an influence when communicating with people from another cultures. The cultural barriers in societies are massive referring to differences and stereotypes are the main reason for this barriers to exist. This document seeks to define gender stereotypes and their impact in interculturality. In addition, this paper explains and makes a contrast in women and men communication in relation with human behavior. As main conclusion of this document it can be argued that gender roles and stereotypes affect intercultural communication processes and create a social impact that hinders the expression of ideas and thoughts between men and women.Introduction Problem statement Literature Review Definition of gender roles and stereotypes Definition of interculturality, and their implications in gender roles Differences in men´s and women´s communication styles Conclusions ReferencesPregradoProfesional en Lenguas ModernasLenguas Moderna

Measurement of W± Z production in proton-proton collisions at √(s)=7 TeV with the ATLAS detector

A study of W(+/-)Z production in proton-proton collisions at root s = 7 TeV is presented using data corresponding to an integrated luminosity of 4.6 fb(-1) collected with the ATLAS detector at the Large Hadron Collider in 2011. In total, 317 candidates, with a background expectation of 68 +/- 10 events, are observed in double-leptonic decay final states with electrons, muons and missing transverse momentum. The total cross-section is determined to be sigma(tot)(WZ) = 19.0(-1.3)(+1.4)(stat.) +/- 0.9(syst.) +/- 0.4(lumi.) pb, consistent with the Standard Model expectation of 17.6(-1.0)(+1.1) pb. Limits on anomalous triple gauge boson couplings are derived using the transverse momentum spectrum of Z bosons in the selected events. The cross-section is also presented as a function of Z boson transverse momentum and diboson invariant mass

Search for diphoton events with large missing transverse momentum in 7 TeV proton-proton collision data with the ATLAS detector

A search for diphoton events with large missing transverse momentum has been performed using proton-proton collision data at is root s = 7 TeV recorded with the ATLAS detector, corresponding to an integrated luminosity of 4.8 fb(-1). No excess of events was observed above the Standard Model prediction and model-dependent 95% confidence level exclusion limits are set. In the context of a generalised model of gauge-mediated supersymmetry breaking with a bino-like lightest neutralino of mass above 50 GeV, gluinos (squarks) below 1.07 TeV (0.87 TeV) are excluded, while a breaking scale Lambda below 196 TeV is excluded for a minimal model of gauge-mediated supersymmetry breaking. For a specific model with one universal extra dimension, compactification scales 1/R < 1.40 TeV are excluded. These limits provide the most stringent tests of these models to date
