The objective of this research is to contribute to the study of the legal definition of Certified Emission Reductions (CERs) and its legal implications for contract negotiation and local sales tax. These definitions will provide greater transparency and legal certainty for negotiations in the carbon market defined by the Kyoto Protocol. The methodology used in the study was to analyze the current National Legislation, literature from government sources and international research organizations. The study showed that the most viable legal classification for CERs is intangible, because the certificates can be equaled to a right which the Clean Development Mechanism (CDM) certificate holder has after its approval. From the understanding of the legal nature of CERs as intangible, we performed an analysis of contractual arrangements applied during the negotiations of the licenses and taxes that could be incident on the certificates. The contract type that was the most appropriate for the negotiation of licenses was the promise to transfer or assignment of future intangibles. In relation to taxation, taxes were the main Income Tax of Legal Entities and the Tax on Financial Operations. However, a full tax exemption could attract interest from new investors in CDM projects, which would result in a more sustainable environmental and socioeconomic development.

This dissertation is inserted in the area of foundations of Education of the Program of Post- Graduation in Education of the Federal University of São Carlos. A study of the field of History of School institutions, which has the object of study Mariana-MG Primary School (a public and primary school). The period chosen has beginning in 1889, to monitor the first initiatives of the government republican of the city in relation to primary public education, and extends until the year 1915- year in which José Ignácio has left the direction of the Group and moved to Ituiutaba-MG. The motivation for the installation of the Group, teachers, students and curricula were observed. Show how was the public education and primary schools in the municipality in the period before the creation of the Group, in calls Isolated Schools, was also a concern of the dissertation. For such was been consulted different archives: Archive Public Miner, Archive of the Municipal Council of Mariana, Acquis of the State School Dom Benevides and newspapers. Tried to relation the particular context The School Group of Mariana- a wider context of the state scenario and, in some moments, nationally. The conclusions pointed to the fact that education carried out in the Group School of Mariana was elitist. It studied mainly the children of declared "republicans" with good financial conditions, while in isolated schools were the poorest and residents of districts and parishes of the city. The quality and the structure of the place of teaching were much better in the Group. The results allow the beginning of a construction of the history of the same, bringing together various documents, which may assist other researchers interested in studying the primary education in the period of the First Republic, and even the School Group of Marian and/or the isolated schools that still has much to be studied.

This study aims to examine to what extent the teaching oriented activities can contribute to the development of an educational computer game with the participation of students in the sixth year of Elementary Education. The teaching oriented activities were developed at first on paper in order to take into account oral and written elaborations of the students while the game was being "gestated". This strategy is based on current methodologies adopted in Computer Science, to build software or computer games that take into consideration the participation of users in the development process, such as "participatory design" or "user-centered design ". To utilize these methodologies we took into account some necessity encountered in the classroom by the actresses and actors of the research (teacher, student, programmer and researcher). The concern with educational computer games in the classroom is inspired on current pedagogical practices, where technology is increasingly being used and in some cases do not cause "real" changes in the traditional methodological approaches in the classroom. The construction of the data occurred in a public school in the inland of the state of São Paulo. The research question was defined as: to what extent the teaching oriented activities of geometric concepts can contribute to the development of an educational computer game with students in the sixth year of elementary school? The research was qualitative and the data analysis was constructed from the organization, reading and analysis of "teaching episodes." Such reviews are based on written and oral elaborations of students, identifying those that can assist on the development of educational computer game. We also intend to understand how such a process takes place, regarding the interaction among students, teacher, researcher and developer. As main findings we highlight the contribution of teaching oriented activities in the reveal of some unexpected situations throughout its development, which allow a special look as for some pedagogical aspects of the game. However, we emphasize a need to discuss some aspects that go beyond pedagogical issues, such as a necessary reconfiguration of the school aiming to promote dialogue with students of the twenty-first century. This reconfiguration is in the sense of conceiving a school that takes into consideration aspects of current society such as the networked information, its nonlinearity, as well as a school that prioritizes creativity and autonomy in educational processes.

Biodiesel is considered as a viable alternative to partially replace fossil fuels. The manufacture process of biodiesel produces approximately 10% glycerin, the main byproduct. Due to the growth of the biodiesel industry in Brazil and abroad, the high volumes of glycerin become a bottleneck in this chain, given that currently use the glycerin market serves a very narrow and specific. Many efforts have been directed to find strategic alternatives for the sustainable use of biodiesel derived glycerin. The competitiveness of the production chain, which originates with the glycerin byproduct of the manufacture of biodiesel, has as one of its determinants identifying technological routes and products to intensify the consumption of this product. In this dissertation, the goal was to determine how it is being done to manage technological innovation and progress in the identification and discussion of the influence which the glycerin is delivering on the biodiesel production chain, seeking possible ways to increase both competitiveness of Brazilian production chain glycerin and biodiesel. To achieve this, interviews were conducted with biodiesel producers, producers and consumers of glycerin and laboratories and research institutes. These interviews were conducted with the aid of a semi-structured questionnaire. A documentary analysis on patents involving the object of study was also performed to verify the main uses found for glycerin. With this, through a chain mapping of glycerol, was described and analyzed the dynamics of their operation and also identified the players who participate directly and indirectly, as well as the productive chains of biodiesel and glycerin are dealing with the management technological innovation aimed at the production thereof. By analyzing the factors of firm strategy, industry standard, technology transfer, leadership, opportunity, appropriability and cumulative, and also with the emergence of new businesses and new markets for the sector was possible to identify a great technological potential for the sector of glycerin. However, due to technological challenges still exist in the production process of biodiesel, this biofuel industry is not focused on these new opportunities.

In the supermarket segment, which is in a growing process of concentration, there are small businesses, mostly on the periphery of cities and dealing with the treatment of lower income populations. These independent businesses have faced their challenges through cooperative actions in the form of central business. Initially focused on the increased bargaining power with suppliers through joint procurement, the central business begin to generate other benefits for its members as an exchange of information and experiences and for synergies through shares in other business areas such as selection, training and human resource management, accounting, marketing actions, etc.. The central business of small supermarkets can be defined as horizontal interorganizational cooperative networks whose effectiveness was associated with the operation and strength of its formal and informal mechanisms of coordination and relational cohesion among its members. This work aimed to study and analyze a group of these networks located within the state of S. Paul compared in terms of its effectiveness, relations between members and the mechanisms through which they coordinate their activities in each network. It was also made an analysis of the dynamic effects of a merger between two networks occurred recently. It was found that, for the networks studied, concerning the aspect of its operations and its process of formation and consolidation, there is evidence of similarities between them in setting up an isomorphic process and the interaction between formality and informality. Moreover, there remain some differences in coordination and cohesion that would be associated.

This study aimed to describe the method used for the kinematic analysis of kicking movements in infants and to determine the effect of additional weighting in the pattern of the kicking movements of infants in the first four months of life. For this, two studies are presented. The first study describes the method used for the kinematic analysis of kicking movements in infants. In the study, four infants were longitudinally videotaped at ages from one to six months and analysis was performed on the Dvideow system. It was verified that the use four video cameras was required. Moreover, six plumb lines were used to calibrate the system and ensure an accuracy of 2 mm. It was concluded, based in the first estudy that the use of the Dvideow system to perform kinematic analysis of the kicking movement in infants proved to be appropriate and feasible. The second study aimed to verify the influence of weights of 1/10 e 1/3 the mass of lower limb in the pattern of the kicking movements of infants in the first four months of life. Fourteen healthy infants participated in the study, longitudinally videotaped. Kicking frequency, foot/panel contact frequency, intralimb coordination pattern, movement time, average speed and straightness index were analyzed. Comparing the ages, we found differences in the kicking frequency, foot/panel contact frequency, movement time, and average speed. Comparing the weighting conditions, we found changes in the kicking frequency and foot/panel contact frequency; the kinematic variables remained unchanged. Therefore, we suggest that during the first four months of life, infants change the kicking frequency according to their ages, the intra-session training and additional weighting. These features are probably the result of intrinsic factors such as increased mass and muscle strength, behavior status of infants, maturation of the Central Nervous System and extrinsic factors such as the weight and the interest in the environment and in performing the proposed task.

In this work, a study of different synthetic ways was made in order to obtain spiro compounds starting from R-(-)-carvone, getting to the formation of cycloheptenone as an intermediate, which undergoes two consecutives alkylations to the formation of a bis alkylated compound which would be submitted to a ring closing metathesis and consequently reaching the spiro compound. The synthesis of the cycloheptenone was started using R-(-)-carvone as starting material through three different routes (Scheme I), obtaining better yields when the third route was used, where the Nozaki reaction is responsible for the ring expansion. Besides that, this route was faster because it has only two steps. Having synthesized cycloheptenone, the first alkylation of this molecule was tested with allyl chloride and potassium terc-butoxide in terc-butanol yielding mono-alkylated product. The second alkylation only yielded the product when the solvent was substituted for dimethylsulfoxide, instead of t-BuOH, using 3-chloro-2- XX methylpropene as alkylating agent. Although the formation of bis-alkylated product was confirmed, the yields were low. Trying to obtain other bis-alkylated products, reactions with 2,3-dichloropropene and 2,3-dibromopropene were tested. Having the bis alkylated product obtained using 3-chloro-2- methylpropene as reagent, the ring closing metathesis (RCM) with first generation Grubbs catalyst 3 was tested. However, after 24 hours, the formation of the desired spiro compound didn t happen under these conditions.

Various authors have denounced the inadequacy of the proposals for continuing education offered to teachers of early elementary, by the distance they keep, in their school curriculum, of school s reality, and the inability to contribute to the establishment of a significant professional and institutional transformation in education, which points out the importance of reflecting and refocusing the proposals of the formation of trainers. Assuming that only a democratically, critical and politically committed formation, with a humanised education of children, youth and adults can contribute to the transformation of individuals and their contexts, the research is rooted on the philosophical and pedagogical principles of educator Paulo Freire. According to these principles, humans are in the world, with the world and with each other, conditioned by time and space in which they live. Therefore, trainers of teachers form and will be forming in their relationships, conditioned by the historical, social, political, cultural and economical system that they make and that influences them. Considering the impact that such system and educational policies exert on the working and behaviour of the teaching professionals, as well as on the functioning of educational institutions, we present the following question: how has the formation of trainers of teachers of early elementary, which act or have acted in continuing education programs, been handled by the Department of Education of the State of São Paulo, and how to reorient the proposals of such programmes within the framework of research and training, from the trajectory of life and occupation of the trainers, through the assumptions of Progressive Pedagogy of Paulo Freire? In order to answer this question, we selected two procedures: the first enabled the wider analysis of the complex processes of formation and auto formation experienced by the trainers, in the course of their personal and professional paths interviews to collect their life stories; the second allowed to identify and analyse the ideas and positions of these people on the relevant themes related to life in the profession, from the freirean frame and the Communicative Critical Methodology - dialogues between each participant and the researcher. Data collection and data analysis are performed from the recording and transcript of conversations with two educators who work continuously with the training of teachers: one that participates in policy making training effected by the Department of Education of the State of São Paulo, and another who works in the implementation of such policies, within the framework of the boards of education. The base of all the research and, most importantly, the results of the dialogues with participants, confirm that the trainers consist of the subjectsubject, subject-object and subject-object-subject relations. These relations establish the historical conditions of living, schooling, social classes, which provide them with learning, thoughts and with the confrontation of situations that affect and oppress, accommodate or rupture, cause barriers or satisfactions, through the constant dialectical movement of doing and redoing, making and remaking. We verify the potenciality of the historical freirean Praxis to the indication of some principles and actions focused on research and proposals for continuing education of (the) educators, in the sphere of schools, public education, universities and trade unions, involving the unity in diversity, the criticality and the dialogue present in the work of Freire and the methodology adopted.

This research proposes to examine the texts ―Obrar‖, ―Ver‖, ―O apanhador de desperdício‖, ―Achadouros‖, ―Sobre importâncias‖ and ―Soberania‖ tha are present, respectively, on the books Memórias Inventadas: A Infância, Memórias Inventadas: A Segunda Infância, Memórias Inventadas: A Terceira Infância, published in 2003, 2006 and 2008 and written by Manoel de Barros, because we start from the premise that the aesthetic discourse of the subjects of these texts represents Barros s architectonics when he works with a construction of a discourses that are opposite of the contemporary social-political system discourses, that´s because while this hegemonic discourse, with its exclusionary and accumulative logic, disseminates a respect to the cartesian and logical world represented by the world of labor, that are the construction of opposite discourses expressed by the subjects of the above texts, which proclaim the world by an optic that values concrete subjectivism and, at the same time, contemplative and erotic, represented by the view and the voice of an adult-child subject, in its childhood. This way, we intend to show the aesthetic construction of these discourses, by a bakhtinian analysis about the subjects, time and space. The theoretical-analytical notions studied by the Bakhtin s Circle (that means the writings by Bakhtin, Voloshinov and Medvedev) are the basic proposals of this research (specifically the dialogism - as a philosophic notion focused on the Russian circle - ethics and aesthetics, subject, chronotope and carnavalization), since they collaborate for a better comprehension around the constitution of the aesthetic discourse proposed by Barros. This way of seeing, understanding and reprsentating the world achieves a new aesthetic meaning which undervalues the sense of speed and accuracy of the "adult world", present in this hegemonic discourse, to turn it into lightness, eroticism and contemplation, that are trangressors and constituentes values of early childhood memories of the ―adult-child‖ subject, ―porque eu não sou da informática: eu sou da invencionática (Barros, 2003, IX).

From the Supply Chain Management (SCM), the logistic function expands its scope within the company, going to exert or support the management and operation of key business processes. Its performance leaves to reduce only the functional sphere ( silo or vertical area ), passing to reach horizontal sphere in such processes. Various sources of literature indicate changes in the logistic function but not characterize precisely or discuss the changes in its scope within the company. In particular, the benefits generated by the involvement of the logistic function on key business processes of SCM have been identified in the literature, but were not identified logistic activities that must execute in each of the processes so that these benefits are achieved. In front of this theoretical gap, the objective of this doctorate thesis was to propose logistic activities necessary for the efficacious operation of key business processes of SCM, generating a conceptual framework that assists in implementing these activities. Such a framework is a guide that can help companies identify, characterize and select the activities that the logistic function can develop in their key business processes. More specifically, this conceptual framework presents, besides the own logistics activities, a way of characterizing these activities, according to four criterions: a) obligatoriness of existence in the company (basic or optional), b) impact on the generation of value (efficiency, efficacy and/or differentiation), c) impact on the dimension of logistic service, d) the integration and coordination with other areas or processes. This thesis used the approach of qualitative research, of descriptive character, of exploratory nature and with experimental study of field. The research method was the multi-case study and the mechanism of data collection was the personal interview realized by a semi-structured questionnaire. This research is also of theoretical-conceptual nature, because it developed a conceptual framework generated from the theoretical review. In three case studies realized, observed consistency in the proposed logistic activities and in its form of characterization. Among the 25 proposed activities, the Company 1 realizes 21 of them, the Company 2 realizes 23 activities and the Company 3 realizes all 25 activities, and all interviewed declared that the set of these proposed activities was complete and consistent.

The adapted sport has spread within adapted physical education and among people with disabilities, given the range of possibilities it offers. The wheelchair handball (WH) is a sport still not very popular, even among people with physical disabilities and has been worked out recently by some professionals in Adapted Physical Education. Due to the fact that it is a new modality and it is still in a phase of construction of knowledge, there are few academic studies related to HW. This research had the aim of filling the blanks that exist in the pedagogical approach of the modality, thus supplying academic support for the future teachers who intend to teach it. Therefore, the aim of the present research was to systematize, apply and describe the program of pedagogical intervention of handball in wheelchairs for disabled people describing its main fundaments. The specifics objectives were: to evaluate the evolution of the abilities in the execution of the sport fundaments in the periods before and after intervention and evaluate in which fundaments the disabled athletes which participated in the study obtained better results. The research was carried out using the experimental methodology, by using the intra-subjects outlining (pre and post test) and AB outlining. The study included four people with physical disabilities, three men and one woman. The data were collected for 12 weeks with 2 sessions in a week (total of 24 sessions, 4 sessions of baseline and 20 intervention sessions) in a city in the state of São Paulo / SP, with all sessions filmed. The data collection was carried out through a protocol of record of task analysis, previously established by the researcher. The analysis was made by three researchers and presented in a qualitative (descriptive) and quantitative way, with statistical analysis (paired t test, considering p <0.05). The analyzed results have margin to select the main fundaments of the WH (handling and displacement with the wheelchair, conduction and control of the ball, throwing, passing and catching the ball, dodging and positioning in the court) and with intervention, we can infer that all the grounds, without exception, displayed an increase of the scores obtained by the athletes, and the fundaments that had the highest scores were exclusive of handball - passing and catching the ball and throwing and the fundament that was less evolution was dodging. This research gave rise to infer that the intervention was effective in promoting the learning of the HW by the participants, and the instrument constructed, it can be applied to other athletes to evaluate the learning of the modality fundaments.

The Restinga forest is a set of plant communities in mosaic, determined by the characteristics of their substrates as a result of depositional processes and ages. And of all the ecosystems associated with the Atlantic, the most fragile and susceptible to human disturbance. In this complex mosaic are the physiognomies of restinga forests of high-stage regeneration (high restinga) and middle stage of regeneration (low restinga), each with its plant characteristics that differentiate them. Located on the coastal plains of the Brazilian coast, suffering internal influences both the continental slopes, as well as navy. His solo comes from the Quaternary and are subject to constant deposition of sediments. The climate on the coast, according to Köppen classification, type is tropical. In recent decades, with growing concern about natural resources and environmental quality, intensified research, resulting in the definition of soil quality (SQ), strongly rooted in the concept of sustainability. To this end, several models have been proposed in an attempt to assess soil quality index (SQI). The monitoring of soil quality should be directed to detect trends that are measurable changes in a period of time. The objectives of this study were: a) Comparative evaluation of the characterization of soil fertility, through chemical and physical parameters under restinga forest of high and low, with respect to distribution of the root in the soil profile, and b) Determine the index Soil Quality for restinga forest in high-and middle-stage regeneration and a resting area with no vegetation. This work was conducted in four locations: (1) Anchieta Island, Ubatuba, (2) Juréia-Itatins Ecological Station, Iguape, (3) Vila das Pedrinhas, Comprida Island; and (4) Cardoso Island, Cananeia. Studies on soil fertility have been made in depths of 0 to 5, 00-10, 00-20, 20-40 and 40 to 60cm for the chemical and physical analysis, with five replicates for each vegetation type, for each study site, each composed of twelve subsamples. Also being evaluated the distribution of the root in the soil profile. To determine the rate of soil quality, chemical analysis were made, microbiological and physical-layer 0-10cm depth. Using two models in determining the rate of soil quality: Additive Model (MA) and Comparative Additive Model (MAC). It is concluded that the root system for all studied vegetation types found in the more superficial layers, 0-10 and 10-20cm, mainly in the 0-10cm (80%), that low levels of calcium and elevated aluminum restrict root development. All the studied have low soil fertility, with base saturation values below 16%, where most of these environments CEC is occupied by aluminum. The additive model produces quantitative results and the additive model comparative quantitative and qualitative results (ground potential), the SQI values were obtained by the MAC for all local and low vegetation types and realistic, demonstrating the low potential for biomass production in these soils, and its low resilience. Values similar to the forests with and without vegetation showed numerically the consideration that the restinga is an edaphic vegetation. And that the use of routine chemical analysis is sufficient to determine the IQS.

The scientific collaboration is one of the indicators to measure the development of research and progress in scientific discoveries. Serves, in other words, in conjunction with other indicators to measure and understand how science develops and direct investment in research. In this study area in particular, nanotechnology, the analysis of scientific collaboration network, converges to an alternative interpretation of the implementation of the Nanotechnology Brazilian Network. This study seeks to analyze the Brazilian scientific collaboration using the methodology of network analysis, together with the technique for generating bibliometric indicators of collaboration in the field of nanotechnology with data extracted from the database Web Of Science in the period 1998 to 2009. To guarantee this, it was necessary to experiment in different view settings for the network organization with the support of the representation of networks in specific software for Social Network Analysis (UCINET) and covalidation results with an expert participating in the network in search of information for the results obtained.These results show the comparison between the main actors of the network using the measures of Degree Centrality, Degree of Intermediation and Degree of Proximity evaluate the role and the relationship between authors and countries in terms of external collaboration and institutionsresearch and Brazilian states in terms of internal collaboration. It also pointed to the involvement of institutions of the State of São Paulo, especially UFSCar, this issue.Concludes by highlighting the importance of the use of methodological tools for evaluating the collaborative process of research and showing changes in the profile collaborative in the Nanotechnology in the analyzed period, which occurs in parallel with the implementation of the network in Brazil.

In survival analysis, some studies are characterized by having a significant fraction of units that will never suffer the event of interest, even if accompanied by a long period of time. For the analysis of long-term data, we approach the standard mixture model by Berkson & Gage, where we assume the generalized modified Weibull distribution for the lifetime of individuals at risk. This model includes several classes of models as special cases, allowing its use to discriminate models. The standard mixture model implicitly assume that those individuals experiencing the event of interest possess homogeneous risk. Alternatively, we consider the standard mixture model with a frailty term in order to quantify the unobservable heterogeneity among individuals. This model is characterized by the inclusion of a unobservable random variable, which represents information that can not or have not been observed. We assume multiplicative frailty with a gamma distribution. For the lifetime of individuals at risk, we assume the Weibull distribution, obtaining the frailty Weibull standard mixture model. For both models, we realized simulation studies with the purpose of analyzing the frequentists properties of estimation procedures. Applications to real data set showed the applicability of the proposed models in which parameter estimates were determined using the approaches of maximum likelihood and Bayesian.

Technology-based firms (TBF s) are expected to fit market demands more easily for being technologically dynamic, more flexible due to their size and their intense knowledge grounds. This research investigated how TBF s of São Carlos/SP have involved in environmental sustainability. It focuses on environmentally friendly strategies employed by companies in sectors that are likely to be environmentally impactful. The survey verifies the environmental performance of firms by identifying if companies have done effective actions, and investigates whether they have proactive, preventive or reactive attitudes in response to pressure from legislation, environmental certification or public pressure. This research characterized those companies considering, among other factors, their relationship with local universities and research centers, characterized the entrepreneurs and verified if environmental certification is usual with the TBF s. This research is supported by work previously done on TBF s and manuals and norms, among other sources. Data were collected by means of questionnaire sent to 10 companies from industrial sectors whose production processes potentially impact the environment. It was possible to draw a partial picture of the environmentally friendly strategies employed, verify the low certification of ISO 14001 and the need for incorporating more effective environmentally friendly practices by those companies. Entrepreneurs of the companies investigated have a high educational level, and the employees have an educational level higher than those usually observed in traditional types of businesses. Most of the founders of the companies investigated come from educational and research institutions of São Carlos which also influence the technological areas developed by the companies.

Alternanthera brasiliana is widely used by Brazilian people as a folk medicine for the treatment of numerous diseases. However, little is known about its chemical composition and the microorganisms that live in association with it. This work proposed the use of dereplication strategies to establish a correlation between chemical compounds present in the plant and the antibiotic activity associated with it. These strategies were also used for study endophytic micro-organisms associated with this plant, since the metabolites present in plant tissues are often result of interaction between plants and different factors present in their habitat, such as micro-organisms. 50 strains of endophytic micro-organisms associated to Alternanthera brasiliana were isolated. High-Throughput Screening strategies, which envolved analytical techniques as LC-PDA-MS, LC-PDA-MS/MS, LC-SPE-NMR and antibiosis assays allowed identification of antibiotic compounds present in the A. brasiliana stems. These compounds are member of oxylipins group, among which we highlight the 13-Z,E-KODE, 13-E,E-KODE, 9-E,Z-KODE and 9-E,EKODE. Furthermore, were identified some depsipeptides compounds produced by a strain of Fusarium fungus, isolated as endophyte of A. brasiliana. Beauvericin, which is one of these compounds , is known for its antibiotic and insecticide activities. This compound was also found in the plant extracts, suggesting that endophyte microorganism could play a role in producing antibiotic compounds inside plant tissues.

This work falls within the field of science teaching aimed at the Brazilian high school and want to investigate some of its relations with an evaluation model, specifically the National Secondary Education Examination (Enem); aiming thus, conduct a study of this examination and discourse of practice teachers in a public school School of São Carlos (SP) of this assessment, based on theoretical assumptions of the STS / STSE for believing that there are close relations that can be woven between these dimensions. As such, there is a documentary analysis of the proposal and proof of Natural Sciences and Technologies and its held focus groups and semi-structured interviews with teachers of high school to a state school in San Carlos, basing on the methodology qualitative analysis, with emphasis on content analysis. In document analysis skills and abilities were observed subtle approaches to STS / CTSA, particularly with regard to the ambivalence of scientific and technological development. The test analysis of natural sciences and their technologies in 2009, also showed shallow approaches to STS / CTSA, since 60% of the questions the aspects of science were not treated with any reasonable dimensions and influences. The context was used in most of the time, as an illustration and not for transformation a reality, and interdisciplinarity was absent in 60% of the questions basically. According to the results found in teaching discourse, evidence of the Enem emphasize social and environmental issues, science is treated as charged content, and technology in specific moments. Furthermore, teachers believe that the context and the interdisciplinary, often show themselves to unnecessary. Moreover, in their speech, there was appreciation of the Enem after its change, which occurred in 2009, the frequent use of examination questions in the classroom as well as the change in focus from teachers to treat the Enem. Regarding the presence of STS / STSE, they emphasized the importance both in the classroom - to bring a broader view of events - and in the evaluations as Enem for not only enhance the application of scientific content.

The hidden camera has been constantly utilized in televised journals as a tool to acquire the news being broadcast. What no one takes into consideration is how the spectators feel about this type of attitude coming from the journalists. This research's objective is to analyze the way in which the spectator attributes meaning to the televised reports obtained through the use of the hidden camera. Therefore, it was taken into consideration factors such as the ideological character of both the broadcaster, responsible for broadcasting the story, with it's news production routines, as well as the journalist itself, who elaborates the story and it's inter-relation with the spectator. The discussion begins with subjects such as genders of speech and the ideology of journalistic speech narrowing down into investigative journalism, for the understanding that it is within' this gender that he journalists make use of hidden cameras. The question that rises is that in the intent of showing the story the journalist drifts away from more ethical approaches, not minding the consequences but merely the impact of the story, using the journalistic fact to intensify the individual appearing in front of the camera as a contraventor. At first this focus shift from the fact to the subject in hand can generate certain sensationalism and destitute the spectator of its right to be in contact with the true message the story should be focusing on. To develop the proposed questions this study was fundamented under the optic of the theorist Mikhail Bakhtin, who discusses the language under the social interactionist perspective and allows us, through his studies, to work with themes such as society, ideology, ethics and aesthetics, and above all, the way the subject interacts with these speeches. Therefore, two televised stories obtained with the use of hidden cameras were utilized, which have been broadcast in televised journals on TV Globo and that were presented to the interviewed subjects. Their answers were of utmost importance, since they allowed the reflection about the subject as well as some important factors.

The Brazilian forest agribusiness represents for 5% of GNP, 17% of agribusiness exports and 8% of total Brazilian exports. In this context, the State of Mato Grosso is no stranger to challenge the country in becoming competitive and sustainable in the long term in this sector. The state of Mato Grosso accounts for about 12.2% or 1.47 million cubic meters of wood production in logs of a national production of 14.12 million cubic meters coming from the native forest, and the second largest domestic producer in 2008 . The chain of wood from Mato Grosso is responsible for the production of logs, lumber, strips, sheet of plywood and others. The research goal was to identify and evaluate the factors of competitiveness of chain of lumber as a way to bring public and private politics aimed at increasing the competitiveness of this system. The methodology uses drivers identified as technology, inputs and infrastructure, management of production units, institutional environment, market structure, governance and environmental sustainability. For the drivers of competitiveness is attributed valuations ranging from very unfavorable to very favorable for sub-factors identified for each driver. Through the rapid appraisal method were interviewed key agents in the chain of lumber by conducting semistructured, as it required information from secondary sources. The lumber-producing regions are located in the central region (Pólo Sinop) northern region (Pólo Alta Floresta and Guarantã do Norte) and northwest (Pólo Aripuanã and Colniza). We conclude that the determinants of competitiveness are: institutional environment and environmental sustainability. The forest management in a sustainable manner becomes conclusive for the chain in the production of lumber in a competitive and sustainable way. However, the chain of lumber needed to reconcile public interests, NGOs, representatives of class and private companies.
