Propuesta de un plan de manejo de residuos sólidos para la conservación ambiental del Parque Zonal Chavín de Huántar del distrito de Quilmaná - Cañete
El presente trabajo de investigación se basa en una propuesta de un plan de manejo de residuos sólidos en el Parque Zonal Chavín de Huántar de Quilmanà – Cañete. Esta investigación está basada en un análisis de diagnóstico, organización, segregación y recolección selectiva que será complementada con un programa de concientización al público en general. El plan se presenta como una propuesta para la conservación ambiental de este centro de esparcimiento recreacional que inducirá al público en general a tomar conciencia sobre la contaminación de residuos sólidos que se viene dando en el distrito de Quilmanà – Cañete.Trabajo de suficiencia profesiona
Insights into the accuracy of social scientists' forecasts of societal change
How well can social scientists predict societal change, and what processes underlie their predictions? To answer these questions, we ran two forecasting tournaments testing the accuracy of predictions of societal change in domains commonly studied in the social sciences: ideological preferences, political polarization, life satisfaction, sentiment on social media, and gender-career and racial bias. After we provided them with historical trend data on the relevant domain, social scientists submitted pre-registered monthly forecasts for a year (Tournament 1; N = 86 teams and 359 forecasts), with an opportunity to update forecasts on the basis of new data six months later (Tournament 2; N = 120 teams and 546 forecasts). Benchmarking forecasting accuracy revealed that social scientists' forecasts were on average no more accurate than those of simple statistical models (historical means, random walks or linear regressions) or the aggregate forecasts of a sample from the general public (N = 802). However, scientists were more accurate if they had scientific expertise in a prediction domain, were interdisciplinary, used simpler models and based predictions on prior data. How accurate are social scientists in predicting societal change, and what processes underlie their predictions? Grossmann et al. report the findings of two forecasting tournaments. Social scientists' forecasts were on average no more accurate than those of simple statistical models
