With the challenge of preparing our students for their role in a global Market, it is a high priority teaching them a second language in order to raise the percentage of speakers, who master the English language. In São Paulo, recent investments have enabled the expansion of the number of Language Teaching Centers (CEL) as well as the introduction of English language as one of the options. Our concern in this context is to understand how educational performance and collateral factors might contribute in the teaching process and the foreign language learning. Starting with the question: “How does the teacher approach can influence the development of the proposed activities with the provided support material of the English course?”, we proceeded to investigate the CEL English classroom, in order to understand the teaching activities and the teacher's relationship with the material. Based on Almeida Filho (1993, 2011), Barcelos (2006a) and Abrahão (2002), an ethnographic-based study was conducted. For data collection, we have used semi-structured questionnaire for the teacher, semi-structured questionnaire for the student, interview with the teacher and teacher observation as instruments in order to see how the teaching action influences the English course offered at CEL. These instruments have allowed us to perform the triangulation of data and its analysis. The results suggested that the teacher's relationship with the course support material it is still attached to the old-fashioned teaching guided by traditional approach, in spite of the training they have gone through. The results have showed that the teacher's approach is prevalent in the consolidation of the support material and guidance for the students. If we are to expect for a new language teaching practice, focused on significant teaching, also contemporary and communicative, an urgent condition is to offer the teachers training courses that bring them to reflection on theories and methodologies in contemporary language teaching. In order to provide both teacher professional development and the improvement of foreign language teaching in basic education.

Birds contribute to many kinds of environmental services, such as predation on arthropods, which results in their population control, and reduced folivory and higher growth rates of plants. In addition, insectivorous birds are sensitive to environmental disturbances, requiring protected areas for conservation and being indicators of environmental quality. In this research, we sampled the insectivorous birds and tested whether they affect the abundance of arthropods and folivory rates. We compared three areas of different successional stages and management, and seasonality in a protected area of Atlantic Forest in southeastern Brazil. The areas selected were anthropic area (“sede”), early and advanced stages of succession. We carried out samplings of birds through 12 fixed points for 13 months and classified species in guilds, grouping the consumers of arthropods between strict and facultative insectivorous. We also proceed a twice bird exclusion experiment (rainy and dry season), comparing arthropod abundance and foliar damage in covered vs. non-covered branches. A total of 186 species of birds have been recorded, with 142 consumers of arthropods. The composition of birds was affected by spatial variation, as the temporal variation presented a diffuse influence. The advanced stage area hosts a higher species richness of specialists, threatened, endemic and with a high degree of environmental sensitivity. The “sede” adds generalist and low degree of sensitivity species. The exclusion of birds resulted in a significant increase in abundance (z=24,682, p = 0) and diversity (z=12,825, p = 0) of arthropods, but this was not reflected in differences in folivory; thus which may be driven by other factors such as the bottom-up effect. The abundance of arthropods showed an inverse relationship with the abundance of strict and facultative insectivorous birds and this control through predation occurred in all areas, suggesting the importance of omnivorous species. The spatial variation of insectivorous birds highlights the potential of each sampled area for maintenance of the functional role of these birds, and this might be considered for management practices.

The main goal of any captive breeding program consists is maximizing the conservation of genetic diversity. Groups kept in captivity are particularly susceptible to the loss of genetic diversity, inbreeding depression and adaptation to captivity, due to their small size. The genetic characterization of wild and captive populations is an important tool both to minimize these impacts and for the conservation of these species, since it enables the development of management strategies aimed at maintenance of genetic diversity. In this context, the main objective of the study was to evaluate genetic variability and paternity for animals of black lion tamarin from Centro de Primatología do Rio de Janeiro, Fundacão Parque Zoológico de Sao Paulo, Parque Ecológico de Sao Carlos and 14 specimen belonging to the Durrell Conservation Trust in England using 15 microsatellite loci. The results of the allelic richness and expected heterozygosity showed similar values of alleles numbers and heterozygosity when compared with other species of Callitrichidae. Factorial correspondence analysis (FCA) showed greater homogeneity among captive animals than wild animals from Capão Bonito. The captive groups showed no differentiation among them and high differentiation from the wild Capão Bonito population. The data obtained herein are fundamental to increase the knowledge in genetic aspects of tamarins and support breeding programs to prevent loss of genetic diversity and inbreeding.

The academic literature often references the articulation of the Catholic Church in the period of the military dictatorship in Brazil (1964-1984), sometimes supporting the coup, sometimes taking part in the democratic resistance - especially after 1968 - with international campaigns, official statements, articulation for the Committee for Justice and Peace, claims from catholic pastoral groups, etc. The bishops, however, never built a monolithic block. This study considers the heterogeneity of the Catholic clergy and political specificities of each region during the military dictatorship in Brazil, suggesting that for every bishop, added to each local context and to the practice concept of the religious message, the weight of the union around his institution may be the explanatory axis for his position in order to bring new perspectives for qualitative analysis of political relations between the Catholic Church and the State in Brazil during the military dictatorship. The specific aim of this research is to investigate the political activity of the bishops of the Catholic Church in São Paulo state dioceses based in São Carlos and Assis. The results of the study are expected to respond to literature gaps on the subject, which until now have mainly focused in the progressive clergy, either in major population centers or in a national level.

The mathematical modelling in the perspective of mathematics education has achieved meaningful progress in the last years in relation to academic and scientific aspects, both nationally and internationally. Mathematics modelling may be considered a consolidated search field. This fact is evidenced considering the number of publications in scientific events, as well as magazines editions and books focused on mathematics education, which range from basic to higher education, as in colleges and universities. However, there are some indications that this mathematics modelling has faced weakness in terms of its application in classrooms of lower secondary levels. Based on this context, our research has investigated the obstacles and difficulties pointed out by recently graduated mathematics teachers of public colleges and universities in Paraná state. These professionals have studied Mathematics modelling during the graduation course, in the perspective of mathematics education, which is related to its application in classroom everyday activities. The methodological approach used to the survey data understanding was the Textual Analysis Discourse. Data collection was conducted through a questionnaire sent via Google Docs to 57 newly qualified math teachers, up to two years after graduation. All these professionals were teaching at public schools of Paraná state basic education. Among these, 26 have answered the questionnaire. We have established four categories covering the main obstacles and difficulties, pointed out by the teachers, subjects of this research, regarding the use of modelling in classroom, which are: (i) teachers’ insecurity in using this methodology in their classes; (ii) poor initial teachers’ training; (iii) difficulties because of traditional and conservative approach of the school system; (iv) difficulties in inserting students in the Modelling environment. These categories have shown that all obstacles and difficulties indicated by teachers about the modelling approach are basically associated to three features of resistance regarding changes in pedagogical practices, which are: (i) personal-emotional aspect, (ii) professional competence aspect, and (iii) institutional aspect.

Interactions plants-frugivores are key components in the complexity of forest communities and their modifications or losses can have profound implications for conservation. The study of the interactions networks has proven an important tool in understanding how communities respond to human disturbance. The aim of this study was to analyze the interactions networks between plants and birds as fruit consumers in Atlantic Forest in southeastern Brazil. The research was conducted in Carlos Botelho State Park (PECB) and addressed three environments with different types of vegetation (open area, and initial successional stages and advanced). The interactions record was performed by direct observation using methods of transect, focal and assistance traps cameras. We evaluated the frequency of visits, number of interactions, nesting and connectance. The network is represented by 63 kinds of birds and 30 species of plants and showed a nested pattern (NODF = 33.63, p = 0) with a connectance low (13%). 255 interactions were observed in 1151 records frugivory. The species that contributed most to the organization's network were also the most important for community maintenance and alien species present in one of the rooms did not interfere in the interactions between native species.

This research aims to analyze the relationship with regard to the knowledge that can be established by students of Basic Education while they are studying the elective course, of interdisciplinary nature: “From shacks to mansions.” In this discipline, the student has the opportunity to explain both the knowledge as the types of relationships established with diverse knowledge, including the extracurricular and school. The instruments used for the construction of the data were: 1- observation of classes developed in the context of elective 2 - records in the logbook of the researcher, 3 - semi-structured interviews with teachers who teach the discipline and students of basic education who attended the subject and 4 – questionnaires applied to students who participated in the discipline. The question that led the research was: “What relationships with knowledge are explained by the students of basic education whilst undertaking the Elective Course, entitled” “From Shacks to Mansions?”. In answering the question I considered the studies of Charlot (2000, 2001, 2005), with regard to the concept of knowing, as well as the research of Kanbach (2005), Barros (2010) and Pompey (2011) which deal with the subject. As a result, it can be said that the knowledge explained by learners does not necessarily address just the school contents. They prioritize and are related to the feelings and opinions that students have about: 1) what they will do in the discipline, 2) the construction of models, 3) interest in the profession, 4) the teaching used by teachers, 5) the treatment given to them by the teachers.

Urban solid waste management (MSW) is a growing challenge for municipal administrations in view of their increasing quantity and complexity. In Brazil, the National Solid Waste Policy (PNRS), approved in 2010, became a reference to foster local public policies, incorporating the concern with sustainability. Some authors have proposed sustainability indicators (IS) to evaluate selective collection (CS), since the sector lacks tools to assist in the decision making and more sustainable monitoring of waste picker organizations. The general objective of this research is to evaluate the use of indicators to characterize the sustainability of selective collection of MSW, having as object of study the cities of Araraquara and São José do Rio Preto. The research was based on the evaluation of PNRS, recycling, general aspects of SC in Brazil and identification of IS for selective collection. For the application, the IS sets, proposed by Besen (2011), were defined as the most appropriate for the evaluation of the SC and of the pickers' organizations, once they were constructed and validated in a participatory way. In 2014, the selective collections of the two municipalities investigated were monitored. The comparative result showed significant qualitative and quantitative differences in the execution of the SC and in the management of waste picker organizations, especially in the operational aspects. To apply the IS, some meetings were held in the two municipalities surveyed. These included municipal managers, technical staff and members of waste picker organizations. All proposed indicators were applied and evaluated, and some, due to difficulties in data collection and lack of proper monitoring, were only estimated. Based on the results of the IS, two sustainability matrices were built, one from the municipal SC and the other from the collector organizations for the two municipalities. The comparative result showed significant qualitative and quantitative differences in the execution of the SC and in the management of waste picker organizations, especially in the operational aspects. To apply the IS, some meetings were held in the two municipalities surveyed. These included municipal managers, technical staff and members of waste picker organizations. All proposed indicators were applied and evaluated, and some, due to difficulties in data collection and lack of proper monitoring, were only estimated. Based on the results of the IS, two sustainability matrices were built, one from the municipal SC and the other from the collector organizations for the two municipalities. The result of the IS application made it possible to calculate the respective sustainability indices. The index calculated for selective collection reached the favorable range for sustainability for both municipalities. For waste picker organizations, the Araraquara index reached the very favorable range for sustainability and, in São José do Rio Preto, the favorable range for sustainability. The similarity in sustainability indices for the two municipalities differed from the observation of CS monitoring in the field. The research concludes that it is necessary to build new IS sets and improve the evaluated IS set to improve the more sustainable management of selective collection with participatory social inclusion.

Autonomous mobile robots are a special category of robots designed for performing tasks without the intervention of human beings. Some robots are designed to perform tasks in completely inhospitable environments such as the earth´s subsurface, the ocean depths or spatial exploration. In order to consider a robot as autonomous, a fundamental premise is to have self-adaptation capabilities. Over the last years, the advances in technology allow the development of self-adaptive systems, which are able to manage themselves to recuperate from faults or even change their behavior and structure in order to improve the quality of the delivered service. A critical point when building any software is its architecture, i.e., its structural organization in a set of interacting components. In this context, reference architecture is a technique that is well known for combining the best practices, patterns and strategies for building and standardizing domain specific software. Nowadays, there is a lack of studies presenting reference architectures for structuring self-adaptive software of mobile robots in order to decrease maintenance efforts. A number of studies claim that self-adaptive systems are based on the control theory and, more specifically, on the use of control loops in their architecture to perform adaptations. Therefore, this master thesis proposes SARAMR, a control loop-based reference architecture whose goal is to make maintenance activities a more productive task. The employment of the architecture divides the whole system in two modules; base application and adaptation module. The adaptation module encompasses the control loops and the base application is further divided into three other components: environment, behaviors and the electromechanical part. SARAMR was qualitatively evaluated by means of the development of two applications: a self-adaptive wall follower mobile robot and another conventional one to performing monitoring in in-door environments. Next, some maintenance activities were created to investigate the effort of applying them. We have observed that the separation of concerns of our architecture allows new components to be added causing less impacts than in systems developed in an adhoc way.

The populations of Neotropical inland fishes have the distribution of their genetic diversity influenced by historical and recent biogeographic factors. Natural barriers such as the formation of waterfalls can disrupt gene flow between populations upstream and downstream. In addition, river fragmentation by hydroelectric dams also impacts on gene connectivity and, moreover, it exposes population to more intense evolutionary forces, such as genetic drift. The effects of habitat fragmentation are more pronounced in migratory species, which move large distances to reproduce. Among these species, Pseudoplatystoma corruscans, a piscivorous catfish, plays an important ecological role as top predator. In addition, this fish represents the main income for thousands of riverine families. Understanding the influence of historical factors on the population structuring is important for species conservation, because it helps in decision making, such as the determination of management units and guidelines for conducting restocking. On the other hand, analysis of recent factors such as river fragmentation can indicate the impact of habitat fragmentation on the population viability, since smaller populations show greater effects of genetic drift and inbreeding. Having said that, we have analyzed the influence of historical and recent events on the genetic diversity distribution of P. corruscans. For historical events, we collected samples of P. corruscans in all basins of its natural occurrence (São Francisco, Paraná, Paraguay and Uruguay) and used markers with slow mutational rates (S7-íntron1, CITB and D-loop). For recent events, we used microsatellite markers, with high mutational rates. We collected samples in four sections of different sizes of rivers bordered by dams (Grande, Verde, Paraná and Paraguay). The mitochondrial markers indicated the existence of two groups, one in the São Francisco basin and another in the Prata basin (Paraná, Paraguay and Uruguay). The three genes analyzed showed private haplotypes for populations in the São Francisco basin, although S7-íntron1 marker has indicated the existence of only one clade for all basins. These results indicate that the geographical separation between San Francisco and Upper Paraná promoted genetic differentiation between populations of the two basins. On the other hand, the “Sete Quedas” fall, which historically separated the Upper Paraná and Paraguay basins, was not enough to promote population structuring. Probably the two basins were connected by headwaters. Thus, we suggest that conservation efforts are earmarked for two large basins (São Francisco and Prata), with a special look to Prata basin, since the species is threatened with extinction in the Uruguay basin, addition to the large number dams present in the Paraná basin. Regarding the river fragmentation caused by dams, smaller river stretches had lower genetic diversity and greater kinship between their individuals, which can result in lower population viability, since there is an increase of inbreeding depression and loss of adaptive genetic diversity. We therefore suggest that studies with other species are performed to determine the stretch minimum size in which the populations of migratory fish are viable, providing guidelines for the construction of new dams.

The improvement in the delivery reliability performance in Make-To-Order (MTO) companies has been becoming an important competitive criterion in the recent market context. Thus, it gets clear the importance of researches able to present tools to help the identification of enhancement opportunities in the matter of delivery reliability. The identification of opportunities requires a structure of diagnosis of the recent situation. However, depending on the performance problem to be diagnosed, a theoretical understructure based on specific scientific knowledge is needed. This work presents the framework developed by Soepenberg et al. (2012c) based on Workload Control (WLC) concepts. Such framework is composed by a structure for the diagnosis process of the reliability performance that allows browsing from the obtained performance to the subjacent causes related to Production Planning and Control (PPC). The aim of the present work is to present the WLC as well as the diagnostic tools with the purpose of elucidating their applicability through the framework developed by Soepenberg et al. (2012c) in a real context through a case study. The results of the case study indicated that the framework is a key instrument for diagnosis due to the accuracy by which it defines the causes of delays of the orders related to the PPC decisions. The application of the framework indicated that the lack of spare parts is the most impacting factor on delays, however this is not a cause only related to the company PPC decisions, but to external factors that are out of the company’s reach. Another result obtained is the verification that most of the orders are concluded before the date set. This is due to the lack of accuracy in the definition of the delivery dates and to the estimative mistakes of the capacity to be used for the maintenance of each part number, whose responsibilities rely on PPC.

In this work we obtain a reduction of the vectorial Ribaucour transformation that preserves the class of submanifolds with constant sectional curvature of space forms. As a consequence, a process is derived to generate a new family of such submanifolds starting from a given one. We prove a decomposition theorem for this transformation, from which the classical permutability theorem for the Ribaucour transformation of submanifolds with constant sectional curvature follows. Given k scalar Ribaucour transforms of a submanifold with constant sectional curvature, we prove the existence of a Bianchi k-cube all of whose vertices are submanifolds with the same constant sectional curvature, each of which is given by means of explicit algebraic formulas. A further reduction of the transformation is shown to preserve the class of Lagrangian submanifolds of dimension n and constant sectional curvature c of complex space forms of complex dimension n and constant holomorphic sectional curvature 4c. In particular, explicit parametrizations in terms of elementary functions of examples with arbitrary dimension and curvature are provided. A decomposition theorem and a version of the Bianchi cube for this transformation are also obtained.

The human being interacts constantly with ecosystems and uses various goods and services from them. These goods and services are called "Ecosystem Services" (ES) and the benefits from these services are called "constituents of well-being." The agroecosystems are modified so that there is greater provision of certain ES, such as food, raw materials and fuels. However, to provide these ES, the agroecosystems need others ES to suits their needs, thus maintaining its production capacity. In agroecosystems, farmers are the main managers of natural resources, influencing the management directly. Therefore, understanding how farmers perceive and interact with natural resources is of great importance. This study aims to evaluate the perception of farmers on the ES, through semi-structured interviews. Analyzing ES perceived by farmers, their relationship with the agricultural practices used, with the impacts caused by agriculture and socioeconomic factors. The farmers interviewed were all in agroecological transition process and belong to settlements Ipanema and Horto Bela Vista, in the municipality of Iperó, near Ipanema National Forest. Within the results, it was observed greater perception of the production ES in relation to regulatory and cultural ES. As well the relevance of the educational level in the perception of ES. Increased awareness of the ES by farmers is of great importance, since it may well assist in agroecological transition.

This study describes the genetic diversity of a population of Hoary foxes (Lycalopex vetulus), animal whose habitat is in the physiognomy of Cerrado, one of the most fragmented and disturbed areas of Brazil. To this end, 33 individuals were captured in a region of cattle ranches in northern Minas Gerais and southeast of Goiás. We amplified 10 microsatellite loci. Our data reveal that these loci are useful in the study of genetic conservation. The genetic diversity present in individuals captured in this study, can be considered high, despite the high degree of fragmentation in the area. The effective population size calculated in this study shows that the genetic diversity supported by the animals studied is representative of a population of approximately 1,300 individuals. We conducted kinship estimates using three methods, one by reading the genotype by software, another through information obtained by field observation studies and a final one, used only when the first two were at odds, based on par visual analysis to analyze all alleles of all loci. With the aid of GPS, the distance between related individuals, paying attention to possible gender’s variation. We conclude that the fox is able to move long distances (over thirty kilometers) and that apparently there is no difference in the male and female dispersal capacity.

This Master s thesis shows a solution for splitting MPTCP subflows in an Openflow network. MPTCP is a network protocol designed to branch a single TCP connection into many subflows. The main idea is to forward subflows th- rough disjointed paths. Commonly, ECMP protocol is adopted together to split flows through distinct paths. Nevertheless, there are many issues that shows that ECMP is not pareto-optimal, such as: ECMP can easily set two subflows from the same TCP connection on the same path and/or set a distinct forward and back forward route to the same subflow. To solve these issues, it is designed MultiFlow, a module which uses a controller for guarantee multipath routing by setting subflows from the same MPTCP connection so that such subflows are forwarded through distinct paths. MultiFlow is evaluated in experimentation where is analyzed throughput and resilience comparing it with Spanning-Tree (STP) and ECMP. The experiments were done by using Mininet: An OpenFlow emulator for experimenting with a set of topologies.

This work presents a didactic proposal for the classes of affine and quadratic functions in elementary school. From our experiences in the teaching profession, we noted that the study of this content requires experimentation and contextualized activities. The study of affine and quadratic functions in basic education is of great importance for abstraction capacity development, solving practical problems and helps to get skills of comparing results, recognizing the characteristics of these functions. Our work is not intended to define affine and quadratic function, but to develop the perception ability of the results that leads to graphs and charts building and can be confirmed using the GeoGebra software. This activity was implemented in two classes of the ninth year of elementary school at Colégio Batista Brasileiro in Bauru. To do this we need four classes of 100 minutes and 1 class of 50 minutes. This is a didactic sequence that requires the use of computers and of the GeoGebra software

In this work we study conditions for the validity of the analogue of Mergelyan’s theorem for continuous solutions of a type of locally integrable vector field. On a domain in the plane, we consider a vector field L that has a first integral on of the form Z(x, t) = x + i'(x, t), where '(x, t) is a smooth, realvalued function. Given a continuous solution u of Lu = 0 on , our first objective was to find conditions on and Z for the validity of the factorization u = U Z, where U 2 C0(Z ()) \ H(int{Z ()}). We will next study this factorization on the closure of . We assume that u 2 C0( ) and that the boundary of is real analytic, then we show in which cases the condition Z(p1) = Z(p2) implies that u(p1) = u(p2), for p1, p2 2 . The cases are divided according to the geometry of the boundary in the points p1 and p2. When is a compact set and u = U Z on , we obtain that u is uniformly approximated by polynomials of Z on .

Nowadays the aging phenomenon has been studied by many researchers because of the characteristics and relevance of the demographic transition and the impact on public policy. Because of this phenomenon, it is considered extremely relevant to the broad scientific production developed view, and in this study we chose to focus on what has been produced in federal universities. This study aims to analyze the Brazilian scientific literature on the topic aging and administration / public management, from scientific publications (qualis A1 and A2 of interdisciplinary and administration areas) and on the registered research groups in groups Directory Research CNPq Brazil (biological areas, health, human and applied sciences). It is a social and exploratory and descriptive study of document analysis and public information. The results suggest that the thematic management / public administration and aging are not being developed directly as both magazines surveyed in the research groups of federal universities. It was decided, therefore, to present a characterization of what both study objects present on the topic aging. Accordingly, it was found that the aging subject is being exploited in different areas of knowledge in an interdisciplinary approach. It was observed that most groups (n = 180) are concentrated in the area of health sciences, with predominant area of medicine (n = 39). As for scientific journals, it was observed that interdisciplinary journals with qualis A2 has a higher number of publications on human aging (n = 262). In this study, further reflection on population aging in the context of public administration studies have concluded that it is necessary, and also points to the need for more studies on aging and public administration.

Masonry is known as a building structure for thousands of years. Cases where masonry elements (several units laided together bonded or not with mortar and grouting) support the building structure are widely found. Until mid-19th century, almost all structures had masonry part of its structural elements, although not all historic construction can be called structural masonry the way we understand it today with high strength blocks. The great expansion on the use of structural masonry occurred after the development of specific techniques and equipment. Moreover, technological development has enabled the production of higher strength blocks, dimensional precision and uniformity. To certify the design specified quality, there is the need of construction technologic control. This is the guarantee of minimum structural performance. Quality control is necessary to receive (or acceptance) the materials and components, including blocks, concrete, grout and the mortar, and finally the acceptance of masonry. This paper presents an assessment of the masonry quality control. Two parts has focus in different topics. In the first, field study cases in São Carlos city are assessed. The cases include concrete and ceramic blocks masonry building, and the quality control plan of each case were checked. The other part, focus on evaluating the several quality control tests on prisms compressive strength. From an extensive database, simulations concerning on the calculation of the characteristic value and coefficients of variation of samples, are assessed and weighted. As a conclusion, we can point that the quality control as required by Brazilian standards are not always followed in practice. About the prism test, we suggest considering to evaluate standard sample size specified today. It may be possible to reduce the number of specimens in each sample.
