Uma proposta contextualizada para o ensino médio: regressão linear
(Universidade Federal de São Carlos, 2019-01-25) Sandre, Orlando Cesar; Venezuela, Antonio Luís; https://lattes.cnpq.br/8722224671269332
This work has as the main objective the teaching of Linear Regression contextualized to High School students. For this, it was elaborated a plan of teaching unity which has four class plans. The class plans are structured so that the student, through the data provided by the teacher, uses it to the analysis and the creation of tables and charts, determination of the linear regression line equation and the determination of linear correlation. The content which will be used is the High Scholl Statistics and Related Function. It will be presented three sets of data with diferent situations where the Linear Regression can be used. The first one is from a hospital where the data are the number of calls in one day and the average daily temperature. The second situation is in a company where it analyses the production and the number of worked hours. The third situation is an analysis of systolic pressure of women and their age. Like this, we look to show in three di erent situations the use of the Linear Regression, which can be adapted by the teacher according to the daily life of their students.
A influência de instituições e do arcabouço institucional na emissão de gases de efeito estufa
(Universidade Federal de São Carlos, 2019-01-25) Tateishi, Henrique Ryosuke; Bragagnolo, Cassiano; https://lattes.cnpq.br/3604206454925741; https://lattes.cnpq.br/8219655367037064
This study investigated the effectiveness of the Kyoto Protocol (KP) in regards to the Greenhouse Gases (GHG) emissions reduction on the first and early second decades of 2000s. It has also taken into account the institutional, such as democracy and property rights levels and development impacts of a countries. Furthermore, it has proposed to analyze the economic performance of Gross Product Value output and the environmental performance concerning the GHG emissions employing a technical efficiency and an environment efficiency measures, respectively. Moreover, it has been proposed to verify the effect of institutional framework on these efficiencies. This study employed a difference in difference model to measure the KP effectiveness and a stochastic frontier analysis to estimate the economic and environmental performances. The results point out an overall low effectiveness of KP. Taking into account different groups of countries with similar characteristics of development or institutional quality, the effectiveness of KP was also low. Countries with low development, low urbanization area covered and high inequality tended to reduce its emissions considering the time difference. Countries with high property rights and democracy level tended to increase the emissions over time. The effect of KP ratification was positive (reduced emissions) for the countries with average institutional and development levels. However, the effect of ratification was negative on the extremes: lowest and highest institutional quality and development levels. The main driver of economic output was capital input and the level of economic output presented a higher share in GHG emissions than the non-renewable energy utilization. The overall economic performance was higher than overall environmental performance. The analysis of the impact of institutional framework on efficiencies suggests mixed results.
