Under the circumstances of the desestatization that penetrate Brazilian economy in the 90‟s, new features in the monopoly of oil by the Union were designed by the constitutional amendment number 9. of 1995. This deep change in the legal regime of oil sector brought the possibility of entrance to small and medium size producers in this industry, especially through the production activities developed in mature and marginal fields of oil, which are located mainly in northeast region of Brazil. Considering that the intervention of state over the economy finds its guidelines and limits in Federal Constitution disposals, the present work investigated in which way states regulation, mainly through taxation rules, has obeyed the constitutional regime in force, and specially, the reduction of regional inequalities principle. By mean, firstly, of an analysis of central concepts (mature fields, marginal fields, small and medium size producers) we observed that the imprecision over the conceptual aspect has constituted an obstacle to a specific states‟ regulation, directed to this newborn class of producers, whose growth has been pursuit by the state. That is verified in the case of concession procedures, and also, concerning the taxation system applied to small and medium size producers. Examining the main constitutional principles related to this universe which are the legality, equality, privileged treatment to small enterprises, contributive capacity, and reduction of regional inequalities we conclude that it is legally possible, a truly specific regulation, including a special taxation regime, to the small and medium size producers whose activities are concentrate over mature-marginal fields, aiming the concretization of the Brazilian state main goals

This essay analyzes tax incentives concepts and existing discussions on national and foreing doctrine, especially in countries that influence our legal culture, such as Germany, United States of America, Spain, Italy and England, providing a detailed study about the requirements that must be observed to ensure that there be a legitimate concession of the same. All this using as argument the Constitutional Charter and the development of the Law, mainly through the principle of objective good faith, which acts as the limiting principle of administrative discretion in granting such tax incentives, as well as creative element of the new duties for the public managers in order to be more effective, efficient and transparent compliance with the pact between the government and society and the objectives pursued by the last. Always chasing a strong argument through a broad historical and philosophical analysis of the institutes discussed. Thus, through studies that reveal the necessary incidence of objective good faith in granting tax incentives to achieve the constitutional purposes, this work does not merely disclose what is wrong, but provides solutions to modify reality hitherto existing, ie, introduces ways to reduce the encumbrance of the odious and ineffective tax incentives in society and to redirect these values unjustly destinated for obscure interests to achieve the real reasons for the existence of tax incentives, especially economic development through the reduction of regional and social inaqualities and poverty eradication

In this work, a performance analysis of transmission schemes employing turbo trellis coded modulation. In general, the performance analysis of such schemes is guided by evaluating the error probability of these schemes. The exact evaluation of this probability is very complex and inefficient from the computational point of view, a widely used alternative is the use of union bound of error probability, because of its easy implementation and computational produce bounds that converge quickly. Since it is the union bound, it should use to expurge some elements of distance spectrum to obtain a tight bound. The main contribution of this work is that the listing proposal is carried out from the puncturing at the level of symbol rather than bit-level as in most works of literature. The main reason for using the symbol level puncturing lies in the fact that the enummerating function of the turbo scheme is obtained directly from complex sequences of signals through the trellis and not indirectly from the binary sequences that require further binary to complex mapping, as proposed by previous works. Thus, algorithms can be applied through matrix from the adjacency matrix, which is obtained by calculating the distances of the complex sequences of the trellis. This work also presents two matrix algorithms for state reduction and the evaluation of the transfer function of this. The results presented in comparisons of the bounds obtained using the proposed technique with some turbo codes of the literature corroborate the proposition of this paper that the expurgated bounds obtained are quite tight and matrix algorithms are easily implemented in any programming software language

Our research has as goal to describe and analyze the main processes related to the activation of conceptual domains underlying the comprehension in the discourse pattern cartoons by the students of third grades of high school, at Professor Antonio Basílio Filho School. Theoretically, we are grounded on assumptions of Conceptual Linguistics, whose interest analyzes our cognitive apparatus in correlation with our socio-cultural and bodies experiences. We intend to check how is the process of meaning construction and integration of various cognitive domains that are activated during the reading activity. That s why, we take the concept of cognitive domains as equivalent to the structures that are stored in our memory from our sociocultural and corporeal experiences and they are stabilized, respectively, through the frames and schemas. The activation of these conceptual domains, as evidenced by our data, supports the assumption that previous knowledge from our inclusion in specific sociocultural contexts, concurrently with the functioning of our sensory-motor system are essential during the construction activity direction. With this research, we still intend to present a proposal confront the expectations of responses produced by students from the activation of frames and schemas with our predictions

A Linguística Cognitiva tem como um de seus principais objetivos descrever e analisar os processos de construção de sentido. Para isso, suas pesquisas pressupõem a existência de estruturas cognitivas oriundas das experiências sensório-motoras e socioculturais dos usuários da língua, as quais são acessadas pelo sujeito durante a compreensão textual. Fundamentada teoricamente nesta abordagem cognitiva da linguagem, esta dissertação tem como objetivo nuclear descrever e analisar como os domínios cognitivos - representados pelos esquemas e frames - permitem ao leitor depreender o risível em textos humorísticos. Entende-se por esquemas os domínios das informações construídas e armazenadas na mente do sujeito, oriundas de sua experiência corporal, como ao movimentar-se ou manipular objetos. Os frames, por sua vez, são os constructos que emergem a partir da interação, estabelecida de forma dinâmica e consensual, entre os sujeitos em contextos socioculturais específicos. Percorremos este caminho não somente por acreditarmos que o efeito de humor decorrente de um texto está subordinado à ativação e ao acionamento dos esquemas e frames armazenados na mente no leitor, como ainda por crermos na existência de vários níveis de compreensão, o que explica a recuperação de trechos humorísticos em um texto. Para confirmar a nossa hipótese, utilizamo-nos da aplicação de um experimento (uma atividade, com textos humorísticos, para alunos dos ensinos Fundamental e Médio registrarem sua compreensão). Para a análise dos resultados dessa atividade, apropriamo-nos, metodologicamente, do processo da introspecção (entendida como a intuição do pesquisador e a responsável pela produção de ideias e raciocínios ao manipular os dados). Durante a observação minuciosa do nosso experimento, chegamos à conclusão de que o humor é apreendido intelectualmente quando os esquemas e frames são confrontados

One of the largest problems of the present time resulting from the economic globalization and the modern technology, of the point of view of the biological rhytms of our organism, it is offering services and production of goods available in 24 o'clock, that it demands organized workers in several work schedules besides the hours of the day. Those schedules cause a series of biopsychosocial consequences in the worker's health, in function of circadian, homeostatic and psychosocial alterations. Accordingly, the aim of this study was to accomplish an evaluation of the effects of several works schedules in the pattern of the sleep wake cycle, anxiety, stress and in the health. We counted with a sample of 274 workers subdivided in 49 daytime worker groups and 225 workers in different shift work schedules with different speeds (rotating shift group, slower day shift group, faster day shift group). From the results analysis it is verified irregularities of the daily activities, stress and alterations in the workers' health in all schedules. It was also verified thata the workers thata presented irregularities in the daily activities were the mroe stressed. On the other hand, the shift works were considered more ansious and associated with bad sleep quality. It was verified that the workers with bad sleep quality were those presented larger levels of dispocional anxiety. There was no statistically significant correlation between bad sleep quality and irregular daily lifestyle. However, it can be affirmed thata shift work schendules doesn't are the main determinant for the circadian alterations, but the answers of the individuals to the shifts work; and that the inadequate behavioural strategies to work with the effects of the shift schedules. In conclusion, individual strategies related to the coping of the work in shift (adaptation and tolerance) should be extolled as indispensable tool in the ergonomic evaluation of the work

The sleep patterns of students entering the university, is accompanied by many factors that can lead to changes in sleep habits, such as academic demands, new social opportunities, reduced parental care and irregular teaching schedules. The irregular pattern of sleep-wake cycle is usually accompanied by several daytime consequences, for example, reduced levels of motivation, performance, concentration, alertness and mood as well as increased fatigue and sleepiness.Thus, there are numerous reasons to support the fact that these students may suffer damage in their academic performance. The aim of this study was to evaluate the sleep-wake cycle (SWC) and cognition in medical students with different schemes teaching schedules. One group started classes at 08am, while the other started at 07am. We analyzed the data from 88 volunteers, 39 from each group. However, only those who participated in both stages of the study (n = 78) underwent cognitive testing. For subjective evaluation of the SWC was used questionnaires to check the quality of sleep, chronotype, daytime sleepiness and sleep habits. For objective evaluation was used actigraphy. For cognitive assessment was used the test MoCA (Montreal Cognitive Assessment). The results indicate that the group has class earlier had a greater irregularity of the SWC and a worse performance in cognitive testing. There was a difference between the schedules the week and weekend in the subjective variables, bedtime, wake up and sleep duration in both groups. The objective variables, time in bed showed difference between the schedules the week and weekend to the group started class at 08am and the variables bedtime, get up time, actual sleep time, time in bed and wake bouts in the class at 07am. In the cognitive test, there were differences between the groups in overall score and in the areas of executive function and memory recall. Thus, it is suggested that the class starting time may cause irregularity of the SWC and the irregularity may cause mild cognitive impairment. Moreover, cognitive testing MoCA was sensitive to detect differences among students, although the difference between the schedules is small

Shift work consists of an array of unusual work hours, such as evenings and weekends, and increasing workload, in order to meet the uninterrupted production, which leads to changes in the quality, duration and regularity of sleep. Research indicates that sleep alteration cause cognitive processes to become slower, unstable and prone to errors, leading to loss of cognitive functions such as visuospatial perception. In this sense, this research aimed to evaluate sleep quality and its relation to visuospatial perception in workers in alternating shifts. Participants were 21 panel operators in a petrochemical company, male, aged 19-53 years. All participants were subjected to schedules of alternating shifts (day and night) of 12 nonstop hours and data were collected from 10 workers who were assigned to the day shift and 11 workers assigned to the night shift. For the sleep evaluation were used the Sleep Diary, the Sleep Habits Questionnaire, the Chronotype Identification Questionnaire and the Pittsburgh Sleep Quality Index (PSQI). The visuospatial skills were assessed using the Rey Complex Figure Test and attention was assessed using a portable version of the Psychomotor Vigilance Task (PVT). The results showed that the general sample of workers obtained poor sleep quality on working days and good sleep quality during the work break. There was shortened sleep duration in the work week and appropriate duration in the work break. No losses were found in the workers visuospatiality, but the good quality of sleep during the work break was correlated to adequate visuospatial performance, for the day shift workers. The attention performance oscillated throughout the work hours, especially on the night shift. It is concluded that the alternating shifts work scheme can be detrimental to the sleep quality workers and a good sleep quality can contribute to a better visuospatial performance

This study has as main objective to verify the effect of the tax and financial incentives granted by the brazilian states, specially in the reduction of ICMS on the investment decision of the entities, which in the last years led to the companies to decide new projects in based on the region that presented the better infrastructure beyond lesser tributary expense. For in such was made an economic valuation of the companies with focus in the beneficiary s optics using an adaptation of the Discounted Cash Flow method to measure the impact of the tax incentives in the value of the companies, this study selected the textile industry segment located in the State of Rio Grande do Norte, Brazil. The results indicated that such incentives created addition in the value of the companies, however the inexistence of incentives would not be enough to a negative decision of investment in the Rio Grande do Norte. The smallest difference between the value with and without incentive observed was 8.9%, and the biggest 31.7%, and the average of value aggregation with the tax incentives represented 18.9%

This scientific investigation begins with the recognition of the authorization granted by the Constitutional Legislator to the State for, relativizing its neutrality towards the private sector, intervene in the behavior of economic agents, through different means, including fiscal incentives and tax increases in order to achieve the objectives and directives of the Federal Constitution, as well as achieve the rights and guarantees also described in the Federal Constitution. Demonstrates, however, that this intervention in the private sector has the power to generate both salutary reflections as perverse and divorced goals from what was established by the Federal Constitution and Multilateral Agreements and this is the basis that justifies the relevance of the study: because of the urgency to provide a thorough analysis of the phenomenon of state intervention in the Economic Order, given the importance of its impacts, both for citizens' lives, as well as for the maintenance of the State established as it is nowadays. From this premise, this research examines the issue of tax policies adopted in the country, focusing on tax incentives, comparing its use with the principles of the Economic Order and the General Agreement on Tariffs and Trade - GATT analyzing whether these have been respected or if Brazil adopted unjustified protectionist measures. From this context, this research approximated different branches of the law, developed through literature review in areas such as constitutional law, economic law, tax law, financial law and law and economics. This study verifies the motivations and objectives that underlie the adopted justifications for the use of tax incentives, as well as its results, seeking to empirically answer if its use is reasonable and consistent with the terms enshrined in the Federal Constitution of 1988 and GATT. The answer to this research question will be sought through doctrinal analysis, jurisprudence and hard cases. Thus, the study begins with the historical evolution of extrafiscality, analyzes the principles that should guide the behavior of economic agents. Subsequently analyzes the legal regime of tax incentives and the results achieved by hard cases in which the tax policies with extrafiscal nature were adopted in order to demonstrate the positive and negative consequences arising from the adoption of this type of benefit
