In this work, it developed an Augmented Reality with Gamification application to assist the learning process of students with intellectual disabilities in general. This application enables the teacher explore various skills with students, how examples, classification, discrimination, color, quantity, problem situations, functionally of objects and association. It was evaluated by two special education professionals and tested by ten students with intellectual disability. In order to evaluate the potential of the application was used quantitative and qualitative methods. In the quantitative stage, questionnaire were applied to the teacher. This questionnaire, regarding the skills presented by the students, were applied prior to the tests with the application get started in schools and were reapplied after a period of two months of tests. For the statistical analysis, it was used the t-test for hypothesis testing and descriptive statistics to organize, summarize and present the data. In the qualitative stage, was evaluated the technical and pedagogical usability of the application in order to the views of experts in the area, making use of questionnaire and observational technical, your opinions about the ease of learning and satisfaction of the application use. The results show that the AR+G Educational Activities contributes to the improvement of skills that, the traditional teaching methods used so far by students that had not been seized by them in a conventional way. It is an easy to learn tool and provides satisfaction from potential users during use. As for learning material, it provides individual knowledge construction facility or collective, presents evidence of engagement and motivation of the students while conducting their activities, as well as more active behavior of the same.

The Brazilian high school, particularly in São Paulo State, has as general objectives the deepening the concepts studied in elementary school, making the student able to continue their studies in higher education and / or vocational courses. In addition, objective the development of critical student's ability to use the mathematical knowledge / concepts studied to understand and solve real situations of their daily lives. However, it is common to see in our schools, students subjected only to the resolution of repetitive exercises, called by George Polya of "routine problems". Consequently, the development of their criticality and their logical / deductive reasoning are affected, not to say, forgotten as goals to be achieved. The research, at the level of Professional Master Degree, reported here was aimed at the "investigation of possible contributions to a methodology based on Problem Solving Theory may have towards the teaching and learning process of trigonometric functions, as well as with the development of mathematical reasoning students of the 2nd year of high school". To this end, it was formulated three issues to be investigated during the course of the research. Are they: (1st) What should be done to generalize the concept of trigonometric ratio (sine, cosine and tangent), studied in the right triangle to the trigonometric cycle? (2nd) How should the transition be held generalization preceded the trigonometric cycle for the study of trigonometric functions in the Cartesian plane in a logical and deductive way? (3rd) What is the contribution that this research brought to my teacher training in math, methodological and didactic perspectives? The investigation results show that the involvement of students in the search for solutions to the problems posed, increased understanding of mathematical concepts worked as well as their application in their everyday situations. Finally, from the my professional training perspective, the research has shown that, when driving the Teaching Process and Learning of Mathematics, from problems "non-routine" and contextualized, the chances of improvement in the understanding and application of mathematical concepts worked as well, interest and involvement of students increased significantly.

This research aims to investigate the process of construction and implementation of the Spanish language Course Curriculum at a Language Center located in the countryside of São Paulo. Therefore, as observed in the teaching-learning process in all years of school it is proposed examination of the entered students in the Spanish course. In this way, a special focus will be given in two important issues: the ways in which managers and teachers form the new classes of languages and which tools are used to evaluate if a student is prepared or not for next levels. For this, it will be used documents as the Resolution 81/2009 and 44/2014, in order to investigate the theoretical basis of curriculum proposal of the Spanish language teaching, also the comparison between the skills and abilities of PCN - EF and MS (2000), the OCN (2006) and the Common European Framework of Reference (2001). It will also be essential the concept of curriculum discussion according to Serrani (2005), Goodson (1995) and Sacristán (2000).

The nutritional food security programs (SAN) can be seen as compensatory policies which aim to assisting a social problem until it is solved within the company itself or can be understood as a program that meets a right of society. The "Viva Leite" program has existed for 21 years is a public policy of food security promoted by the State Government of São Paulo that provides pasteurized milk to children from poor families aged between six months and seven years. We study in particular the Block 27 area of the program formed by the municipalities of: Angatuba, Buri, Campina do Monte Alegre and Paranapanema. Our hypothesis that the program "Viva Milk" in block 27 can be understood as a fragmented network between the municipalities that make up the block whose institutionalization process is associated with the operation of this network, the mechanisms and formal and informal practices of operation linked to relational cohesion actors among its members. The objective is to study the functioning of the "Viva Leite" program in the block 27 municipalities checking if there is a dense or fragmented network between the municipalities, their cohesion from a relational point of view and to what extent the program is institutionalized. To do this analysis we set out how the network is structured on the block and in each municipality analyzed the structural and relational point of view of network theory. The theoretical line of work is neoinstitutionalism with cut in network analysis. In the design of networks’ structure of the program didnt find that there connections in program management between the municipalities, each municipality makes its management. We understand how the network is fragmented. . It made the crossing of the activities of the actors in each municipality seeking to verify the use of the program's official rules and the recreation standards and procedures whereas the extent that the rules are used and recreated bringing uniformity to the practices the program was becoming institutionalized. We find greater cohesion relations in so far as it headed toward the city managers cores. Thus, it was found major relational cohesions in relations involving beneficiaries and local managers offices. From this perspective we conclude that the program is not yet settled more presents intermediate characteristics of typifications within a habitualization step.

This paper has the purpose of to discuss the characteristics of municipal institutional arrangement of international relations and the impact of its work on public policies carried out by municipal institutions of city hall. For that, initially, the determining factors that legitimate the international action of the sub-national governments were found, subsequent to, we done an observation of the characteristics of municipal institutions of international relations of Brazil. Finally, we analyzed the institutionalization of international action of a particular subnational government as well as the activities that have been done by institution that takes care of external works, and we analyzed the governmental management of this organism. We examined too how is its involvement with other municipal institutions. Aiming at exemplify this matter, a case study of the International Relations Municipal Sub-Secretariat of Belo Horizonte/MG was done, because the Law 9.011/2005, which institutionalized this organism, recommends that this organism should work together with the other municipal institutions so that it can fulfill the purposes described in this same law.

In this study, it was made the determination of nutrients (in the forms of orthophosphate, total phosphorus, nitrogen series, total nitrogen and total dissolved carbon) and physicochemical variables in surface waters and sediment of the Monjolinho River, in São Carlos – SP, Brazil. Six sampling points were selected (stream head waters, at the UFSCar, upstream to the effluent treatment plant, Água Quente Stream, downstream to the effluent treatment plant and near the river mouth), in which were possible to observe a tendency of increase of the impact suffered by the aquatic body along its course. These tendencies were more pronounced from the region of the upstream to the effluent treatment plant (where the urban superficial flow carries the wastes to the river) to the region downstream to the effluent treatment plant. At the Água Quente Stream and downstream to the effluent treatment plant points, the input of non-treated and treated wastewaters are responsible for the substantial increase in the concentration of nutrients and alterations in physicochemical variables that reflects the impact suffered by the river. It was also noticed a seasonal tendency of variation in the measured values in agreement to the pluviometric indices of the studied region. Evaluating the Redfield ratio values, it is postulated that the phosphorus is the limiting nutrient in this ecosystem. The Tukey tests, HCA and PCA applied to the results allowed to separate sampling points into different groups according to the data obtained for each chemical analysis, showing that there is a tendency of increase on the impact suffered by the water body from its head waters to the sampling point downstream of the effluent treatment plant.

The orchid bees have always been considered promising for studies of the evolution of social behavior and reproductive division of labor. This is due to the fact that the orchid bees are the only members not clearly eusocial in corbiculate clade. In this study, the correlation between genetic relatedness and reproductive skew was investigated in the genus Euglossa, one of the five genus of Euglossini tribe, in order to support the understanding of the evolution of reproductive division of labor in Euglossini. Among the five genera of Euglossini, Euglossa is the most suitable for studies on the evolution of reproductive division of labor, because in this genus can be found solitary, communal and primitively eusocial species. Twelve nests of Euglossa cordata (Linnaeus, 1758) were analyzed. In this species, the foundation process is solitary, but small colonies are formed during nest reactivations, with females establishing different types of associations, in which their relatedness differs. During reactivations, one of the females performs oophagy and then oviposition in brood cells previously operculated by another females, consequently leaving a larger number of offspring. The behavioral analysis associated with relatedness estimates, made through the use of microsatellite markers, indicated that the dominant female perform oophagy followed by oviposition in all operculated cells by the subordinated bees. The reproductive skew was complete, regardless of the type of association established between the interacting females, and so reproductive skew and genetic relatedness was not associated in this study. Furthermore, the nesting biology of Euglossa was also studied, given the information scarcity about the nesting process in most species already described for this genus. Using the technique of trap nests, 43 nests of Euglossa were sampled. This study provides new information on the nesting biology of this genus, especially with regard to natural enemies associated with nests.

The literature on female assertiveness has presented expressive changes in women‟s repertoire throughout the years. It also has started the discussion on the influence of sociodemographic variables in these changes. Thus, it is pertinent to analyze the role of women in a variety of contexts in contemporary society, since a long history of coercion against the female sex has occurred. Allied to this situation, we can affirm that Brazilian studies on social skills, of which assertiveness is a class, are in a period of ascension. However, the studies that specifically discuss assertiveness are still scarce, especially concerning the behavior-analytic approach. In addition, little has been discussed about this matter in Psychology and it is possible to verify a lack of specific evaluation tools on assertiveness produced in Brazil. These findings and considerations are in the foundation of this thesis‟ objectives, which is organized in four studies. The first manuscript aimed to identify and characterize the academic production of national studies on assertiveness, seeking to determine the “state of the art” and describe the development of this research area. The second part sought to analyze the changes in female assertiveness, from the analysis of historical and current contingencies. The third part of the study aimed to construct and validate a scale to assess multimodal assertiveness, encompassing frequency indicators, cultural context and hidden variables as factors associated to this construct. As a result, the unifactorial, 16-item Assertiveness Skills Inventory (IHA, in Portuguese) was produced. It presented high validity in the frequency indicator, measured by internal consistency (α=0,82). The fourth part had the objective of characterizing the assertive repertoire of women and to verify the association of sociodemographic variables with the overall assertiveness score. One hundred and ninety women from the State of Maranhão – higher educated and currently employed in the labor market – have participated in the study. The analysis of all indicators showed higher average scores for the assertive skills „Defend others in group‟ and „Ask friends for help‟ in all indicators, except for „discomfort‟, which showed the highest score for „Approach for sexual intercourse‟. The lowest means of the other indicators concentrated in „Approach for sexual intercourse‟ skill. The data aligns with literature that indicates that the higher the social skills repertoire, the lower the discomfort level and vice-versa. Regarding sociodemographic variables, positive correlation was found for the quantity of undergraduate diplomas and a negative correlation was found for the time of migration from countryside to capital. This means that more higher education degrees and shorter time of migration from countryside to urban area are associated with a higher frequency of assertive ability to self-report. The influence of cultural variables and formal education is discussed to explain assertiveness in this sample. It indicates the need of further research with this population with varied sociodemographic and cultural characteristics. The main contributions of this study are the methodological and empirical references for the analysis of female assertiveness in our country

This research's goal is to analyze the meanings attributed to work and education by youngsters of Milton Santos Settlement of landless agricultural workers, located in the city of Americana, state of São Paulo, Brazil, considering an education view not reduced to the space of the school. Education and work are subjects very present and valued by the Brazilian youth. Although employment has increased recently, young people continue to be the biggest share of unemployed in the country and the majority employed in precarious jobs. Understanding this reality contributes indirectly to learn the influences to the youth life in the daily routine of the youngsters, who recuperated their experiences with agriculture, with jobs out of the rural space, with the school, with the care for their children, and with the participation in the struggle for land. For this, sixteen semi-structured interviews were made, besides many visits to the settlement to observe the field, culminating in the analysis of the narratives of the youth, which converged into four groups: 1 – Difficulties in conciliating work and education; 2 – Dilemmas related to conciliating work, education and family; 3 – To study is a priority.The meanings of work and of education were multiple, work being related to income, independence and professional achievement, while education was referred to exclusion, dreams and to more liberating processes regarding the participation in social movements.

The Erythrinidae family is a small group of Neotropical Characiformes, comprising only three genera, Hoplias, Hoplerythrinus and Erythrinus. Hoplias malabaricus, Hoplerythrinus unitaeniatus and Erythrinus erythrinus must correspond to groups of species, considering the extensive chromosomal diversity that they present, including different sex chromosomes systems. Therefore, these fishes offer excellent opportunities for evolutionary investigations, given the different chromosomal characteristics between their representatives. Recent studies allowed the taxonomic characterization of six poorly or not studied Hoplias species (H. aimara, H. lacerdae, H. intermedius, H. brasiliensis, H. australis and H. curupira), present in several South American river basins’ and popularly known as “trairões” due to their large size. This study aimed to characterize the chromosomal evolution occurred in this particular group of species, in the light of its recent review and taxonomic identifications. For this purpose, in addition to classical chromosomal analysis, cytogenetic mapping of repetitive DNA sequences using specific probes was used for fluorescence in situ hybridization (FISH). The results showed the sharing of a great homogeneity in the species´ karyotype macrostructure, with 2n = 50 and karyotypes composed only by meta- and submetacentric chromosomes without the presence of differentiated sex chromosomes between the sexes. In turn, the karyotype microstructure, as revealed by the analysis of components of the repetitive fraction of the genome showed interspecies differentiation, thus confirming the recent taxonomic revision of these species based on their morphological characteristics. This evolutionary scenario, highlighting the conservation of chromosomal macro-structure, sharply contrasts with the scenario found in the representatives of H. malabaricus group, where a conspicuous chromosomal variation can be observed between different populations of this "nominal species." Environmental aspects related to the way of life, as well as intrinsic chromosomal features, may influence the coexistence of these contrasting models of chromosomal evolution among congeneric species of Hoplias.

The aim of this study was to measure the technical and economic efficiency differentials in citrus production among farms in the State of São Paulo, Brazil, as well as to identify the determining factors of these differentials. In addition, it was also an objective to investigate the main characteristics of citrus production technology (partial elasticities, returns of scale, economies of scale and the elasticities of substitution of production factors). Primary data was collected from a representative random sample of 98 rural properties. Stochastic production, cost and profit frontier models were used, assuming the Cobb-Douglas and the translog functional forms. In order to identify the factors determining the efficiency differentials, the single-stage stochastic model proposed by Battese and Coelli (1995) was adopted, and a set of hypotheses were tested, based on different standpoints of economic theory (NEI, ECT, theories of human capital, theories of production management, etc) as well as on the characteristics of citrus production. The results of the study showed the existence of technical inefficiency (28.4% on average), as well as inefficiency of cost (30.6% on average), and of profits (55.3 on average) among the farms. The translog production and cost frontiers indicated the existence of an initial zone with strong growing returns/economies of scale which go into exhaustion until decreasing returns begin to occur/diseconomies of scale. The optimum scale, calculated from the parameters estimated in the translog production frontier, showed to be between 70,000-100,000 boxes, while the optimal scale for the translog cost frontier showed to be between 130,000-300,000 boxes. One of the explanations for this difference is the lower prices for fertilizers and labor paid by large farmers, which is a source of pecuniary scale economy. As for the factors determining the differential in technical, cost, and profit efficiency, it was possible to verify a significant effect coming from a set of variables which can be divided into structural (irrigation, greening and land consolidation), managerial (adoption of management tools, use of plural forms of governance, choice of marketing channels, rural production diversification and technical assistance), institutional (occurrence of problems in the contracts of sale, formation of expectations, perception of enforcement in commercial contracts and financial leverage), and human capital (schooling and access to information). Therefore, some of the main research hypotheses were corroborated in the empirical analyses. Lastly, based on the results of the study, a set of suggestions that may subsidize the formulation of public policies and private strategies for the citrus production of São Paulo were made.

Ce travail présente une analyse du problème de l'anthropologie chez Foucault, à la lumière des concepts de sujet et d'homme, dans ses textes du milieu des années 50, et des années 60. Le point de départ, c’est la thèse complémentaire à l'Histoire de folie, intitulé Genèse et structure de l’Anthropologie du point de vue pragmatique de Kant. Ensuite, on fait l’analyse des textes des années 50, dans lesquels on trouve les origines du problème de l'anthropologie au sein de la recherche sur la psychologie et la maladie mentale. Enfin, on fait, sous la même perspective, l’analyse des textes principaux de la période archéologique, jusqu'à Les mots et les choses. On trouve que, depuis la Thèse Complémentaire, l'anthropologie est défini comme un regard spécifique sur l'homme, au seuil entre ce qui lui est interne (l'âme / esprit, la subjectivité), et ce qui lui est externe (son corps, d'un côté et, de l'autre, ses relations de savoir / pouvoir avec l'autre). Dans ces dualités répose aussi une «anthropologisation du savoir », en raison de la confusion dans l'analyse de l'homme, entre le domaine empirique de son existence concrète, et le champ d'analyse de ses facultés en tant que sujet transcendantal, thème fondamental de Les mots et les choses. En outre, on observe dans ces relations entre l'intériorité et l'extériorité un élément de normalisation anthropologique, présente dans la régulation du comportement humain à laquelle, cependant, il est possivel aux sujets humains de s’en échapper, en vue de sa liberté de «faire quelque chose d’eux-mêmes ». Ainsi, la critique de Foucault à l'anthropologie implique aussi une critique de l'anthropologie, dans une critique de la vérité, héritier de la pensée de Kant, mais aussi en s'en opposant, une fois qu'elle se donne comme une critique historique des formes par lasquelles les vérités sont constituées.

This work aims to develop a novel method to design educational games, following Extreme Programming and Scrum Agile Methods and screenplays under the dilemmas and mechanical game re-guise concepts, which are already widely accepted in the literature. Workshops using the proposed method were conducted in order to identify the demands of educators and students from elementary and middle school and also the viability in the implementation of the method as a support tool to the teaching process. The validation results and the method acceptance were evaluated by statistical tests, which are also widely explored in the literature for similar samples. The final remarks show the successful methods evolution and their validation results under the considered classrooms context.

The objective of this research is to develop a study around the teaching of Philosophy in the Italian secondary schools, based on the education reform fostered by Giovanni Gentile, Ministro della Pubblica Istruzione (Secretary of the Department of Education, in English). We will focus this study during the years of 1923 - 1925, when the reform was implemented, until the moment it suffered some changes promoted by the Secretaries of Education who succeeded Gentile. In order to achieve these objectives, we divided the research into three sections. The first section is to familiarize the reader with the history of this research, which is presenting the first years of the fascist regime implemented by Mussolini. This way, we will discuss the development of the fascism as a myth and investigate its primary impacts in the education and in the Italian society as a whole. The second section will focus on the introduction of the philosopher Giovanni Gentile. It will talk about the application of his education reform in the Italian schools, which had been stagnated since 1859, without significant accomplishments. In the third section, we will cover the teaching of Philosophy, which is present in the secondary schools but excluded from other types of schools, such as technical institutes and complementary schools. This reform has ensured the presence of the teaching of Philosophy in the curriculum but has not been enough to guarantee it to be offered to all Italian youths. The reasons that led to this unequal treatment on the teaching of Philosophy will be reviewed during this research.

In this study, the wettability of porous anodic alumina (PAA) surfaces modified by plasma was investigated. The porous anodic alumina films were grown on aluminum substrate using a two step anodization procedure in oxalic acid solution under potentiostatic regime. The surfaces of PAA films were modified by plasma treatment or plasma deposition techniques. Prior to surface modification, the impurities were removed by a plasma cleaning procedure. Oxygen was used in plasma treatment in order to produce hydrophilic surfaces. On the other hand, the plasma deposition (in HMDSO or HMDSO + argon mixture) was performed to produce hydrophobic surfaces or less hydrophilic surface. Electropolished aluminum without PAA film were used as reference. The influence of substrate morphology on wettability was analyzed. The morphological characterization was performed by scanning electron microscopy (SEM). The microstructural analysis was carried out using Fourier Transformed Infrared Spectroscopy (FTIR). A goniometer was used to measure the contact angle and evaluate the wettability of electroplished aluminum and PAA films. The results showed that the wettability of the samples was affect by chemical interactions of functional groups on the surface deposited after plasma treatment. The effect of the porous surface morphology on wettability was not significant compared to the plasma treated films with new chemical interactions effects.

Paxos is an active replication algorithm that keeps the same shared state consistently among servers that handle requests from an application. It is unusual to find applications where the main processing happens through a replication algorithm such as Paxos, mostly due to the high number of exchanged messages required to keep the state consistent. This restricts the system scalability to a handful of replicas. To increase the applicability of active replication, we would like be able to not only make the capacity of processing proportional to the number of servers employed, but also change dynamically the number of server according to demand. In this dissertation we explored reconfiguration on systems that use active replication. We proposed two mechanisms: (1) efficient protocolo for state transfer; and (2) incorporation of new replicas in the system with no significant increase in the cost to keep the whole system consistent. Our approach uses both mechanisms to create reader replicas, capable of answering all application requests without taking an active part in the costly operations of the Paxos algorithm.

The thesis consisted of three studies described below. The study I, entitled "Hemodynamic and metabolic response during aerobic and resistance dynamic exercise in different intensities: A cross-sectional study on implications of intensity on safety and symptoms in patients with coronary disease". Where the objective of this study was to evaluate the clinical and physiological responses during resistance exercise in loads of 30 and 60% of 1-RM on the leg press 45° and compare the responses with maximum aerobic exercise. The evaluation included aerobic test on cycle ergometer and resistance test in leg press 45°. Ventilation, hemodynamic and clinical measurements were performed. The results showed that 60% of resistance exercise and the dynamic test increased variables response studied in compared the load of 30% in resistance exercise. We conclude that high repetition of resistance exercise results in physiological changes at an intensity comparable to maximal aerobic exercise. Further, the study II, entitled "Resistance training improves heart rate variability and muscular performance: A randomized controlled trial in patients with coronary artery disease study" The objective was to investigate the effects of a high repetition program/low load resistance training (RT) (HR/LL-RT) in heart rate variability (HRV) in muscular strength and endurance in patients with CAD. Test were carried out in 1-RM test in leg press 45°, HRV was captured in the supine position before and after eight weeks of RT. The HR/LL-RT program consisted of an exercise using leg press 45°; (three sets, twenty repetitions, twice a week for eight weeks). The results showed that after eight weeks RT there was a significant increase in the values of the RMSSD, ApEn SD1 indices and only the TG (p<0.05). There was a significant decrease in Mean HR after RT for TG (p<0.05). Additionally, there was significant improvement in muscular strength and endurance only for the TG (p<0.05). We conclude that eight weeks of HR/LL-RT is a sufficient stimulus to change heart function, muscle strength and endurance in patients with CAD. Finally, the study III, entitled: ''What the impact of resistance training on hemodynamic, autonomic and metabolic variables in coronary artery disease patients? The randomized controlled trial of eight weeks''. Where the objective was to evaluate the hemodynamic, metabolic, and the HRV effects during maximum intensity tolerated in constant loads protocols during dynamic and resistance exercise before and after eight weeks of resistance training program of low intensity and high reps (RTLHr) in patients with CAD. The results showed increase in maximum and submaximal load (p<0.01) and attenuation of the hemodynamic performance in the higher load (p<0.01) and reduced lactate concentration compared for TG. During the cycle ergometer exercise, there was attenuation of hemodynamic performance and increased minute ventilation (p<0.01). Finally, the TRBAr produced greater parasympathetic contribution (RMSSD and SD1), after RT. We conclude that eight weeks of RTLHr may attenuate the hemodynamic stress, metabolic and autonomic during resistance exercise with cardiovascular and autonomic beneficial effects also in the dynamic exercise.

Intersectoriality can be defined as an implementation strategy management actions in public, private or public / private services. In conceptual aspect, it can be understood as a political immaterial strategy for dealing with social inequalities and poverty, complex and multifactorial phenomenon, requiring therefore a complex approach. The configuration of social protection services in Brazil, built after the 1988 Constitution, sought to institutionalize social policies as universal, equitable, decentralized and democratized by means of social control, responding to the need to repay the resulting social debt policies pursued by governments authoritarian, with models of centralizing welfare and social protection. This study of exploratory and descriptive, conducted a review of published and indexed scientific literature databases in the humanities and social sciences of nature and life and related fields, in order to discuss the implementation of public policies in Brazil from the intersectoral guideline proposed to operationalize the decentralization and promote the constitutional principle. He drew a picture of scientific production in the field of Brazilian public policy, focusing on public management of intersectionality, through a search of articles published in scientific journals indexed in databases from 1988, historical and normative framework for analysis intersectoral this guideline in the law of creation of the Brazilian social protection services. The research analyzed the intersectoral approach building on the management of public policies. Such a theme makes it possible to rethink the operation of the implemented Brazilian public policies through advance directives proposals from the 1988 Constitution. This study concluded that scientific texts are in an incipient phase and concentrated in health, organized in political, administrative and epistemological earlier that the area of social and disconnected from social security assistance. Of which comes from research and reporting practices experiences, particularly those associated with the operating scale implementation of social policies. These intersectoral experiences of nature operating in public administration do not solve the structural problems of an economic society, only possible evidence inclusive political projects and situated in the defense of social rights guaranteed in the constitution.

In Brazil, species introduction in freshwater ecosystems has become an important topic in conservation ecology, as it is one of the main causes of biodiversity loss. Invasive species benefiting from the lack of natural enemies outside their original geographic distribution might represent a highly competitive pressure to the native species sharing the same resources of the invaded areas and may lead to changes in the abundance and richness of natural communities. In this sense, for a better understanding of these relationships, it is possible to study experimentally the interactions between invasive and native species evaluating competition effects. So, the objective of this study was to assess, through an experimental approach, if there is intraspecific and interspecific competition between two cichlid fish: a native species, the cará Geophagus brasiliensis and the exotic Nile tilapia Oreochromis niloticus. The objective was to examine if there is differential growth and feeding under different fish densities in consortium or separated. The experiment was conducted in Setor de Aquicultura do Polo Regional Vale do Paraíba - APTA Regional in the municipality of Pindamonhangaba, from March to June 2014. In order to assess the intraspecific competition of each species due to increased density and, comparing them with interspecific competition when the two species coexist in the same tank, five treatments with four replicas were considered. Fish diet studies suggest that there was no intraspecific and interspecific competition for food in this experiment. Despite the morphological similarities between the two fish species, the weight gain is evident and it can be assigned to the treatment itself. Intraspecific competition was not detected, as there was no significant decrease in the average weight gain for both species with increasing density of individuals of the same species. As for the interspecific competition, the results suggest that space availability may have been the main factor of dispute between species, since there was no significant change in diet and the consortium of these species benefited O. niloticus in much higher proportion than G. brasiliensis.

The identification of aspects and circumstance considered as challenges and opportunities inherent in the implementation of the urban transport system operated by the Light Rail Transit - LRT in Brazilian cities are at the heart of the goals of this work. Developed a methodology where theoretical research done through the literature review and the application of Delphi method, used for the query to a group of subject matter experts, formed the basis for completion of the study. The results show its role of facilitator and propellant within the context of urban policies in cities where it already operates on a consolidated basis in several countries, creating expectations that can achieve the same effects in Brazilian cities, which will be deployed and that way, if firm as an efficient urban transport mode, an agent of sustainable urban mobility. It is concluded that, given the reality of urban mobility conditions in most Brazilian cities large and medium-sized, the opportunities for this innovative transport system and holder of proactive features, observed by the methodology applied, are feasible, since , its viability is proven through studies covering aspects such as; the existence of demand, the investment capacity of the governing body, the prospect of financial return and integration with existing modes, to name the most important. Also through the applied methodology, it can be concluded that the challenges for its implementation in the country are of great proportions, starting with the high investments required, through the formulation of policies that integrate the various segments of urban management and culminating with the effective participation of population most interested. Thus, it is understood that the opportunities and challenges for the VLT go hand in hand, on the prowl for decisions that put to the test.
