Fracaso escolar y su vínculo con el maltrato entre alumnos: el aula como escenario de la vida afectiva

El valor que la narrativa proporciona al estudio de los procesos subjetivos relacionados con la violencia, nos permite observar a través del análisis de un sujeto, lo universal en lo particular. En este texto se podrán identificar la pluralidad de sentimientos y emociones que acompañan, y se constituyen en los elementos configuradores y articuladores del comportamiento disruptivo en el ámbito escolar, de manera especial relacionados con la violencia entre iguales en las instituciones educativas. La historia de “José”, es una muestra significativa de un alumno, objeto de estas reflexiones, que expresa mediante sus narraciones, los aspectos simbólicos y afectivos que están detrás, o que subyacen en la determinación de la toma de decisiones en problemas que derivados del maltrato, tienen como consecuencia situaciones relacionadas con el rendimiento, la deserción y, ocasionalmente el fracaso escolar, que fue este caso

Entre escuelas y balas una aproximación a los Mass Shoting (tiroteos masivos)

This article is a historical and theoretical compilation of some studies that have analyzed the phenomenon of massive pulls in schools from psychology, psychiatry, criminology and pedagogy. This allows the authors to make an academic inquiry into these phenomena that affect school climates and demonstrate the serious problem that indoor cases involve in educational institutions. The approach of this bibliographic material will lead the reader to know an approach to the phenomenon of massacres in educational institutions, the state of school violence, a school criminality, a brief presentation of the chronological history of the massive shootings in the last years of modern History of the planet and the variant of social networks that move around a crime executed by a student.El presente artículo es una recopilación histórica y teórica de algunos estudios que han analizado el fenómeno de los tiroteos masivos en las escuelas desde la psicología, psiquiatría, criminología y pedagogía.

El abordaje de este material bibliográfico conduce al lector a conocer una aproximación al fenómeno de las masacres en instituciones educativas, pasando de un estado de violencia escolar a criminalidad escolar a una breve presentación de la historia cronológica de los tiroteos masivos en los últimos años de la historia moderna del planeta y la variante de las aristas sociales que se mueven alrededor de un crimen ejecutado por un estudiante

Manifestaciones de violencias entre alumnos de educación superior: Los usos del WhatsApp

En este artículo se presentan resultados de una investigación sobre algunas manifestaciones de violencia a través de WhatsApp entre alumnos de Educación Superior, realizada en 11 programas educativos. Conocer los nuevos tipos de maltratos que hacen y sufren a través de WhatsApp los alumnos de facultad inscritos en una universidad pública de la ciudad de Guadalajara, Jalisco, México. Fueron encuestados 541 alumnos(as) en una muestra probabilística de una población de 17 000 estudiantes, trabajando con un 95% de nivel de confianza para estimar una proporción por medio de un intervalo bilateral con un enfoque conservador obteniendo un límite de error de .041 (4.1%). Entre los resultados más relevantes encontramos que un 48% de la muestra se ha sentido incómodo y disgustado por fotografías pornográficas que le han enviados sus contactos sin haberlas solicitado y sin que le notificaran del envío de estas imágenes; los mismo ocurre con un 37.4% de la muestra con alumnos(as) a los que enviaron videos pornográficos. Este tipo de mensajes constituyen nuevos maltratos que ofenden a quienes los reciben, como ocurre además con un 18.7% del alumnado a quienes les han hechos memes aparentemente inofensivos, pero que hacen sufrir a quienes en ellos aparecen al ser ridiculizados. Otro hallazgo importante, fue el relacionado con la indiferencia y cómo está se ha convertido en nuevo tipo de violencia que sufren un 77.8% de alumnos.//In this article we present the results of an investigation regarding violence demonstration through WhatsApp among students of Higher Education, carried out in 11 educational programs. To learn the new types of mistreatment that faculty students enrolled in a public university in the city of Guadalajara, Jalisco, Mexico do and suffer through WhatsApp. 541 students were surveyed as part of a probabilistic sample of a population of 17 000 students, working with a 95% confidence level to estimate a proportion by means of a bilateral interval with a conservative approach obtaining an error limit of. 041 (4.1%). Among the most relevant results, we found that 48% of the sample has felt uncomfortable and disgusted by pornographic photographs that their contacts have sent without their consent; the same happened with 37.4% of the sample of students to whom pornographic videos were sent. These types of messages constitute new abuses that offend those who receive them, which is also the case for 18.7% of the students who have been targets of seemingly harmless memes, however, those who appear in them suffer ridiculing. Another important finding was the one related to indifference and how it has become a new type of violence suffered by 77.8% of students

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

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.

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

Search for stop and higgsino production using diphoton Higgs boson decays

Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass
