- Abstract
Este estudio tuvo como objetivo evaluar los elementos clave que permiten un liderazgo inclusivo para el desarrollo educativo peruano, a través de la experiencia canadiense. Mediante de un enfoque mixto, se utilizó el diseño anidado concurrente de varios niveles, la muestra se conformó por dos grupos: 1029 participantes de 20 instituciones educativas en Perú y Canadá, a quienes se aplicó la escala de liderazgo inclusivo LEI-Q, el segundo grupo estuvo conformado por 10 directores canadienses a quienes se aplicó un focus group. Más del 90% de canadienses evidencian que existe un liderazgo inclusivo en las instituciones, mientras que, en Perú el 79% precisan no haber liderazgo inclusivo. Los directores canadienses hicieron énfasis en tres elementos clave que permiten impulsar el liderazgo inclusivo: aprendizaje crítico reflexivo, fomentar relaciones con la comunidad educativa y promoción del liderazgo inclusivo. Para hacer que la inclusión sea una realidad en las escuelas públicas peruanas se requiere un énfasis continuo en la condición humana y una atención deliberada a los marcos de transformación sociocultural y sistémica.

Cancer is a serious issue for society as it is among the top causes of mortality worldwide. The burden of cancer is increasing due to various factors such as the ageing population, unhealthy lifestyles, environmental pollution and more. It is estimated that more than 10 million people will die from cancer-related illnesses in 2021. Therefore, it is important to understand the cancer burden and develop effective prevention strategies to reduce its impact on society (Garland et al., 2012). The cancer burden is the total cost of cancer care, including direct medical costs such as treatments and hospitalizations, indirect costs such as lost productivity due to illness or death, and intangible costs such as suffering and emotional distress. This burden is increasing every year due to advances in medical technology, increased prevalence of certain types of cancer, and rising healthcare costs. While there is no onesize- fits-all solution, there are a variety of prevention strategies that can be used to reduce the threat of cancer. These strategies range from lifestyle changes, such as eating a healthy diet and exercising regularly, to medical interventions, such as vaccines or medications (Bode and Dong, 2009). To reduce this burden, doctors have been looking for ways to prevent and treat cancer. Materials and methods such as "immunotherapy, biomarker therapy, radiation therapy, radiation therapy, chemotherapy, and targeted therapy" are being used to reduce the cancer burden. Also, one such strategy is chemoprevention, which involves using drugs or other agents to reduce the risk of cancer development. Chemoprevention has been studied extensively and is effective in reducing the threat of cancer. [ABSTRACT FROM AUTHOR]

- Abstract
Bootstrap methodology is evaluated in heteroscedastic models applied in the prediction of the Lima Stock Exchange Index (S & P / BVL), period 2017 - 2019. Predictions were obtained using the parametric methodology from the algorithm of heteroscedastic GARCH processes with Bootstrap proposed by Pascual (2006) being this generalized for other types of heteroscedastic models and were compared with real values. The performance of both methodologies was evaluated. The models that best fit the series are the ARMA (1,1)-EGARCH (1,1) models with assumptions of the residuals with Normal and t-Student distributions with 5 degrees of freedom. The comparative study showed that the application of the Bootstrap methodology in the series of returns of the Lima Stock Exchange Index, allows prediction intervals with greater and equal amplitudes in some horizons compared to the parametric methodology. The construction of prediction intervals for volatilities were also obtained with good performance, thus, this is an alternative for their construction in heteroscedastic models. La presente investigación tiene el objetivo de analizar y evaluar la metodología Bootstrap en modelos heterocedásticos aplicados en la predicción del Índice de la Bolsa de Valores de Lima (S&P/BVL), periodo 2017 – 2019. Las predicciones se obtuvieron mediante la metodología paramétrica y la metodología Bootstrap, y fueron comparados con valores reales, partir del algoritmo de procesos heterocedásticos GARCH con Bootstrap propuesto por Pascual (2006), siendo éste generalizado para otros tipos de modelos heterocedásticos. Los desempeños de ambas metodologías fueron evaluados. Del estudio se obtuvo que los modelos que mejor ajustan a la serie son los modelos ARMA(1,1)- EGARCH(1,1) con supuestos de los residuales con distribuciones Normal y t-Student con 5 grados de libertad. El estudio comparativo mostró que la aplicación de la metodología Bootstrap en la serie de los retornos del Índice de la Bolsa de Valores de Lima, permite obtener intervalos de predicciones con mayores e iguales amplitudes en algunos horizontes en comparación con la metodología paramétrica. También se construyeron los intervalos de predicción para las volatilidades, siendo ésta una alternativa para su construcción en modelos heterocedásticos.

- Abstract
This article shows a comparison of confirmed cases and death from Coronavirus disease (COVID-19), among South American countries, considering cases per million inhabitants and standardizing the time of infection, from the day of confirmation of case zero to each country. The objective is to more uniformly evaluate the spread of this virus and thus evaluate the result of the measures taken by governments against COVID-19, since various research centers show comparisons without taking into account the proportion of inhabitants, nor the time (days) of contagion between countries. In addition, we provide short-term predictions and an estimate of the end of confirmed cases in the most affected countries., El presente artículo muestra una comparación de los casos confirmados y muerte por la enfermedad por Coronavirus (COVID-19), entre países de Sudamérica, considerando casos por millón de habitantes y uniformizando el tiempo de contagio, desde el día de confirmación del caso cero para cada país. El objetivo es evaluar de manera más uniforme la propagación de este virus y de esta forma evaluar el resultado de las medidas adoptadas por los gobiernos en contra del COVID-19, ya que diversos centros de investigación muestran comparaciones sin tener en cuenta la proporción de habitantes, ni el tiempo (días) de contagio entre países. Además, proporcionamos predicciones a corto plazo y un estimado del fin de los casos confirmados en los países más afectados.

Purpose: This study examines the relationship between the economic, social, and environmental dimensions of social responsibility and the level of knowledge regarding technology social responsibility among Peruvian university professors. This study assessed the technical and social responsibility knowledge level among Peru's public and private university instructors. Design/methodology/approach This study was conducted using a quantitative research approach and a cross-sectional research design utilizing a survey questionnaire to acquire primary data. This study's sample comprised 1,159 public and private university professors in Peru. The academics of Peru's public and private institutions contribute to data collection. 280 valid questionnaires were utilized for data analysis with Partial Least Square (PLS). Findings According to the study, the economic, social, and environmental dimensions of social responsibility favor Peruvian university teachers' awareness of technology and social responsibility. In addition, it is discovered that there is a considerable knowledge gap between public and private university teachers regarding technology and social responsibility. Practical implications This study's findings help resolve concerns about low levels of knowledge among Peru's public and private colleges, which may contribute to the promotion of technological social responsibility among institutions. Originality/value Prior studies in the literature examined technology social responsibility, but professors' knowledge is not included. In Peru, comparative research between professors of public and private colleges has not been conducted in the past. [ABSTRACT FROM AUTHOR]
