This study proposes the production and characterization of blends of ABS/PC through reuse of discarded PC in the automotive panel production process. The developed alloy ratios are (ABS/PC) 30/70, 50/50 and 70/30, in addition to the neat materials. For comparative purposes the mixtures were developed for both materials recycled PC (PCr) and neat PC (PCn). The blends were processed in a twin screw extruder under controled heating temperature.

This work is composed of three essays dealing with the themes of exchange rate and competitiveness for the Brazilian, North American and European economy. The first part aims to verify empirically the validity of the theory of purchasing power parity and the Balassa-Samuelson effect for the Brazilian and North American economy, from 1948 to 2016. The second part seeks to analyze the relationship between exchange rate and wages for the brazilian economy in the post-trade liberalization period, from 1999 and 2015. The third part analyzes the influence of intellectual capital and its components on the national wealth of European Union countries. Thus, theories about the topics are presented an, econometric techniques of time series and analysis panel data has been used to analyze the data collected. The results of the first essay showed that there is no causal relationship between PPP and the Balassa-Samuelson effect, in addition the tests revealed a long-term causality between the variables. The results of the second part did not show evidence of cointegration between the exchange rate and wages, suggesting that, in the period analyzed, it is not possible to conclude that there is any relationship between the exchange rate and wages for the Brazilian economy. However, Granger's causality tests suggest that over time wages cause changes in the exchange rate. The results of the third research fail to find evidence of the influence of structural capital on national wealth, on the other hand, relational capital was positive and significant in all estimated models. Finally, despite finding evidence of a positive moderating effect between innovation and sophistication in the relationship between human capital and national wealth, it is not possible to validate that there is a moderating effect on the relationship between intellectual capital and national wealth.

Autism Spectrum Disorder (ASD) is one of the conditions that causes most damage to a child’s neurodevelopment. When caregivers are not provided with strategies of intervention/amelioration/prevention of behavior problems, the task of taking care becomes an overload. The general objective of this study was to verify empirical evidences of the efficiency of a psychoeducational program for parents to manage behavioral difficulties of children with ASD. The sample was composed of 8 boys with ASD, aged from 5 to 11 years (mean 8 years; standard deviation 1,93), and their respective caretakers, aged from 22 to 63 years old (mean 38,4; standard deviation 15, 95). The parents data collection instruments were: a) Form to assess demographic and socioeconomic data; b) Adult Self-Report for Ages 18-59 and Older Adult Self-Report for Ages 60 and Above (ASR/18-59 and OASR/60-90+); c) Parental Style Inventory (PSI); d) World Health Organization Quality of Life WHOQOL-bref; e) Questionnaire on the main difficulties parents/caretakers have; f) Checklist for control of program orientations; g) Questionnaire on caretakers satisfaction with the program; h) Diary record monitoring; i) Psychoeducational program for parents, which had the objective of orienting parents on the characteristics of the disorder, educating them on the use of strategies to manage behavior problems and informing on empirically tested behavior intervention strategies. Data collection instruments of children behavior were a) Child Behavior Checklist for Ages 1½-5 and for Ages 6-18 (CBCL/1½5 and CBCL/6-18); b) Behavior Problems Inventory (BPI-01); c) Aberrant Behavior Checklist (ABC); d) Questionnaire on use of mental health services. The program consisted of eight meetings, held once a week, with duration of 3 hours each (total 24 hours). Participants were assessed before, during and after the intervention. The main results indicate high adherence and satisfaction with the program, as well as a positive assessment of the possibility of employing in their routine the orientations received in the program. Positive empiric evidences were found in the behavioral and mental health patterns of the children and caregivers, as well as in their quality of life.

Cellular automata are discrete complex systems and also fully distributed computational systems, with arbitrarily simple local processing. One of computations that can be made with cellular automata is sorting of numerical sequences. Sorting is a quite relevant topic and widely used in computing, as one of its fundamental processes. This research aimed at the development of sorting algorithms based on one-dimensional cellular automata. Two new versions with range 1 and 3 have been proposed, inspired by the characteristics of existing studies in the literature. In the analysis carried out, the proposed cellular automata have advantages over the approaches that originated them.

O presente trabalho tem como objetivo a realização de um estudo prático e normativo acerca da prática da Eutanásia, dentro do âmbito da sociedade e do direito brasileiro, trazendo principalmente como base para a discussão, uma análise acerca da ponderação dos Princípios da Autonomia e da Dignidade em relação ao Direito à Vida, ante o cenário do “direito à morte”. Desenvolver uma visão mais abrangente do assunto, desviando a questão exclusivamente de uma análise meramente formal e legal, sobre a prática da Eutanásia, trazendo novas interpretações e pontos de vista em razão da evolução da sociedade, com reflexos para o Direito, como se reflete por exemplo, na tendência da adoção do common law no Brasil, através de uma aparente inclinação a uma atuação mais permissiva, compreensiva e humanitária do judiciário atual. Ainda durante o desenvolvimento, há o objetivo de se traçar um paralelo em relação à situação da eutanásia no Brasil com outros lugares do mundo, em razão da liberação desta prática em alguns países, o que será realizado por meio de um estudo comparativo que envolva a legislação e os critérios adotados pelos outros países. Por fim, levantar ainda quais as dificuldades da efetivação desta prática e quais seriam as consequências da eventual liberação desta prática no Brasil, que até então prevê tal fato como crime.

The present work proposes an interdisciplinary investigation concerning the logic of the concept ART, that is, about the circumstances that justify the categorization of something through the predicative expression “is art”. Its fundamental historical premise is that in the final decades of the nineteenth century artistic production underwent structural changes whose radicalization in the following centuries unmistakably evidenced the limitations of aesthetic theories oriented by the classical model of definition. As the processes of categorization in the most diverse theoretical fields were understood in the light of this model until the midtwentieth century, it is possible to say that the aesthetic theory was confronted with the necessity of a new vision on the nature of these processes. Based on this premise, the guiding problem of this work was thought as an analog of the demands for scalability involving information systems: how to account for an exponential expansion and diversification of data without compromising the operational effectiveness of the support responsible for its processing? Hence the idea of a “scalability challenge” to the aesthetic theory and the problem of its overcoming, mainly in face of the unfolding of contemporary art. Taking the discussions produced in the context of contemporary philosophy as its bibliographic horizon, more specifically in the tradition known as “analytical philosophy”, this work defends the thesis that the cluster concept theory elaborated by the English philosopher Berys Gaut offers elements for an understanding of the logic of the concept ART capable of overcome the scalability challenge in a satisfactory way.

This dissertation aimed to compare and evaluate the predictive power of an artificial stock market model developed by agent-based modeling techniques (ABM). An empirical study was carried out to forecast the values of certain shares of B3, the Brazilian stock exchange, through the model of Collective Behavior in the Stock Market, created by Silva (2014). The values generated were compared with the reais collected between the dates: 06/05/2019 and the end date on 08/17/2020. The environment used was the Netlogo. The sample of data for comparison included 299 observations, with a simulation of 5400 models for each stock. The analysis comprised the comparison between the forecast and the actual closing price within established periods. The selection of models was performed using the Directional Accuracy test of Pesaran-Timmerman (2006). The results of the models were compared with a model based on statistics, using an ARIMA algorithm, by Box and Jenkins (1976). The models showed satisfactory initial results for the predictive power.

Results and contributions: To propose an analytical model to support pricing decisions and to attendance the demands of services, collaborating with entrepreneurs, managers of small and medium-sized companies, who need support to conduct and improve their activities. In this study, it was plausible to cooperate with literature and practice, generating useful knowledge through the use of the so-called interventionist research methodology. Objective: To define the most appropriate method of costing to be used by service providers and to develop a management model to assist small and medium-sized service providers in the Bragantina region in their decision-making to minimize uncertainties in margin of contribution. Relevance of the chosen subject: According to the difficulties of analyzing the demands for services to be provided and establishing objective parameters to the pricing, managers end up having a great uncertainty in the pricing of these services, being this stage of pricing of great importance for these companies, we chose this subject to be studied. Impact on the area: An interventionist model of budget management research was presented that uses the accounting and the experience of the entrepreneur about the company and the sector in which it operates. Through this research, we have created a model that is based on accounting data and the manager's experience. With this combination, we built a budget solution proposal for small entrepreneurs to use. Methodology: The qualitative interventionist approach was used for this study, which was based on the analysis of the data collected through interviews with the manager and the partner of the company researched and by the data made available by the management of the company itself.

This master's thesis is formed by a critical and poetic analysis of the work of the contemporary artist Nazareno Rodrigues and author’s own work, mainly considering the intersection of its multiple languages in the context of visual arts; by the creation of a series of drawings in sewing, in dialogue with one of the works of the mentioned artist; by the development of an art research methodology; and by a relational analysis with Italo Calvino's book Six proposals for the new millennium. The critical analysis includes a theoretical part, divided in quantitative and qualitative analysis, with the development of an unpublished methodology of research. The poetic analysis includes the elaboration of an art exposition, in dialogue with one of the works of Nazarene and with the book of Calvin. The reflection on the work of Nazareno Rodrigues, Carolina Vigna and Italo Calvino is relational, intersemiotic and interdependent. The conclusion produced both a theoretical reflection and the revision of the author's artistic production.
