La educación musical y el rendimiento escolar : resultados estudiantiles en lectura y matemática de los beneficiarios de Sinfonía por el Perú

La educación musical alrededor del mundo ha demostrado su impacto en el rendimiento escolar de niños y adolescentes. En Perú, existen iniciativas de la sociedad civil, como Sinfonía por el Perú (SPP), que se plantean como reto desarrollar capacidades en los niños y de esa manera, tengan mejores oportunidades en el futuro. El presente estudio busca determinar la relación que existe entre la educación musical con el rendimiento escolar en un caso peruano. Es así que, a través de cruce de bases de datos de la Evaluación Censal de Estudiantes (ECE) del Ministerio de Educación y la base de datos de beneficiarios del programa Sinfonía por el Perú, se quiere indagar si existe una relación positiva entre la pertenencia al programa y el buen rendimiento escolar de sus participantes. A través de los resultados descriptivos y la metodología Propensity Score Matching (PSM) se determina que sí existe una relación positiva, pero esta herramienta cuantitativa deja de lado otros factores que pueden estar influyendo en este resultado. En vista de ello, se ha complementado el análisis mediante la aplicación de entrevistas a beneficiarios, padres de familia y personal del programa, para determinar y conocer su percepción respecto al impacto del programa en el rendimiento escolar. A partir de lo señalado por los entrevistados, se identificó una relación fuerte entre la educación musical y el desarrollo de capacidades emocionales y son estas capacidades emocionales las que permiten al beneficiario poder desenvolverse mejor en el plano escolar, impactando en su desenvolvimiento académico; además, los beneficiarios cuentan con una red de soporte en casa que les permite participar del programa como cumplir con sus actividades escolares, lo cual también estaría influenciando en su desempeño escolar. Esta investigación es una aproximación inicial a la comprensión de la relación entre el rendimiento escolar y la educación musical en nuestro país, no solo teniendo información estadística de primera mano, sino testimonios de los beneficiarios, quienes sostienen que el programa ha tenido un impacto positivo en su desarrollo. Así, esperamos que la presente investigación pueda ayudar a resaltar la importancia de la educación musical para el desarrollo de los niños, ya que aportan herramientas para su desenvolvimiento, no solo en el campo musical y escolar, sino para su desarrollo como persona

El presente trabajo de investigación titulada “Análisis de parámetros microbiológicos y parasitológicos empleando Lemna minor y Eichhornia crassipes en aguas superficiales, distrito Santa Catalina, Moyobamba, 2023”, tiene como objetivo Evaluar la eficiencia en la disminución de los parámetros microbiológicos y parasitológicos empleando las especies Lemna minor y Eichhornia crassipes en aguas superficiales. El tipo de investigación fue aplicada, con un diseño de investigación cuasi experimental. La muestra de esta investigación está constituida por 120 litros de agua obtenidos de la captación, donde se dividió en 6 estanques experimentales concluyendo 20 litros para cada prueba, cantidad necesaria para cada aplicación del tratamiento. Se trabajo con 3 dosis diferentes (Lemna minor: T1=50 g, T2=75 g, T3= 110 g) y (Eichhornia crassipes: T4=50 g, T5=75 g, T6=110 g). Los resultados obtenidos mostraron que, en la mayor cantidad de análisis hechos, en los parámetros microbiológicos y parasitológicos, la mayor eficiencia se dio con el tratamiento T4, con un porcentaje promedio de 91,36 % de remoción en coliformes totales, más que en la mayoría de parámetros analizados. De esta manera, se confirmó que, de los 6 tratamiento realizados, el tratamiento T4 se encuentra óptimo para los demás parámetros analizados

Quality of life in patients with clinically localized prostate cancer managed with modern radiotherapy: impact on bowel habit, sexual function and urinary symptoms

Pacientes con Cáncer de próstataObjective: The increase in the diagnosis of tumors in early stages, associated with similar life expectations among the different treatments, create a challenge for both patients and treating doctors when choosing the best therapeutic option. The objective is to assess the impact on the quality of life in the sexual, intestinal and urinary fields in patients with localized prostate cancer who received treatment with modern radiotherapy. Methods: Descriptive observational study in which the validated EPIC-26 and SF-36 surveys were applied in the period between December 2015 and November 2018, in order to assess quality of life in men with localized prostate cancer before and after modern radiation therapy. Results: Surveys were applied to 70 individuals. In the EPIC-26 survey, relevant changes in the quality of life for urinary incontinence were found, with a previous average score of 81.75 (100 - 12.5) versus a subsequent 72.99 (100 - 0). In the SF-36 Health Questionnaire it was found that there is no significant difference in the overall quality of life, with an average score of 77 (99 - 31) and 76.63 (100 - 39.58) respectively. Conclusion: There is a tendency to oversize the impact of radiotherapy on the quality of life when there is a curative intent in patients with localized prostate cancer. Our study only demonstrated a clinically relevant difference in urinary incontinence, which allows us to suggest that most of the alterations in the quality of life could be secondary to natural changes in aging.https://orcid.org/0000-0002-8707-4277https://orcid.org/0000-0003-1271-5612https://orcid.org/0000-0001-8202-9744https://orcid.org/0000-0002-7540-4734https://orcid.org/0000-0002-0346-7349Revista Internacional - No indexadaN

Identification of heavy-flavour jets with the CMS detector in pp collisions at 13 TeV

Many measurements and searches for physics beyond the standard model at the LHC rely on the efficient identification of heavy-flavour jets, i.e. jets originating from bottom or charm quarks. In this paper, the discriminating variables and the algorithms used for heavy-flavour jet identification during the first years of operation of the CMS experiment in proton-proton collisions at a centre-of-mass energy of 13 TeV, are presented. Heavy-flavour jet identification algorithms have been improved compared to those used previously at centre-of-mass energies of 7 and 8 TeV. For jets with transverse momenta in the range expected in simulated $\mathrm{t}\overline{\mathrm{t}}$ events, these new developments result in an efficiency of 68% for the correct identification of a b jet for a probability of 1% of misidentifying a light-flavour jet. The improvement in relative efficiency at this misidentification probability is about 15%, compared to previous CMS algorithms. In addition, for the first time algorithms have been developed to identify jets containing two b hadrons in Lorentz-boosted event topologies, as well as to tag c jets. The large data sample recorded in 2016 at a centre-of-mass energy of 13 TeV has also allowed the development of new methods to measure the efficiency and misidentification probability of heavy-flavour jet identification algorithms. The heavy-flavour jet identification efficiency is measured with a precision of a few per cent at moderate jet transverse momenta (between 30 and 300 GeV) and about 5% at the highest jet transverse momenta (between 500 and 1000 GeV)

Particle-flow reconstruction and global event description with the CMS detector

The CMS apparatus was identified, a few years before the start of the LHC operation at CERN, to feature properties well suited to particle-flow (PF) reconstruction: a highly-segmented tracker, a fine-grained electromagnetic calorimeter, a hermetic hadron calorimeter, a strong magnetic field, and an excellent muon spectrometer. A fully-fledged PF reconstruction algorithm tuned to the CMS detector was therefore developed and has been consistently used in physics analyses for the first time at a hadron collider. For each collision, the comprehensive list of final-state particles identified and reconstructed by the algorithm provides a global event description that leads to unprecedented CMS performance for jet and hadronic tau decay reconstruction, missing transverse momentum determination, and electron and muon identification. This approach also allows particles from pileup interactions to be identified and enables efficient pileup mitigation methods. The data collected by CMS at a centre-of-mass energy of 8 TeV show excellent agreement with the simulation and confirm the superior PF performance at least up to an average of 20 pileup interactions

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
