This paper focuses on the relations between the adversative and concessive notions that are conveyed by the conjunctions and, also, on the operations that are accomplished in the generation and in the constitutive process of the enunciations where we can find this marks. The research intents to observe how the enunciation construction and organization translate the intersubjective relations. In this way, the parlance is treated as an interaction mean and we aim to analyze its implications on the language teaching/learning process. In order to discuss this matter, we observe how students in different levels produce meaning in theirs texts. To do so, we chose theoretical proposals that we considered essential to enunciative studies, such as Theory of Enunciative Operations by Antoine Culioli, through which we intent to propose speculations around the notion concept. This author s work approaches the articulation between parlance and natural languages and, furthermore, between texts production and grammar, through the representation (the perception the subject has about himself and the world around him how he reads the world), referential (dialogue establishment through discursive materialization discursive-lexical-grammatical marks) and regulation (mediation process between interacting interlocutors) operations, which are presented as responsible for the dialogical process constitution. We emphasize, in this way, the importance to propose an enunciative grammar in the teaching process that can approach these operations. We believe that this perspective change is fundamental not only to researching purposes, but as well to teaching.

This work has the objective to analyze the perspective of the research professors (―professores pesquisadores‖) about the possible consequences of the work intensification, on the graduate level, for the teaching and other activities at the undergraduate level. Such process occurred in the context of the adjustment of the national economy to the capital mundialization, and the reform of the State apparatus. It established a north to the reconfiguration of the identity of the public universities and brought consequences for the teaching work. To meet our objective, 13 semi-structured interviews were realized with the teaching personnel of FEMEC-UFU. This university have been chosen with basis on the data and the research analysis of Sguissard and Silva Júnior, as published in their book ―O trabalho intensificado nas Federais: pós-graduação e produtivismo acadêmico - 2009. The results presented in this book and the fact that the FMEC graduate course received grade 6 are suggestive of a high productivity as well as an intensification of the teaching work. The interviews were analyzed by a systematization of subtopics arisen from an attentive lecture. These subtopics CAPES, work intensification, techno-scientific production (academic productivism), public-private partnership (PPP), young professors versus old professors, philosophy and organization of the teaching unity... or department... are closely related to our objective and to our research object. Such procedures revealed the complexity as well as the contradictions existing in the relationship between the graduate and undergraduate university practices. Ou research hypothesis was partially corroborated by the analysis of the data we obtained. In view of the current conjuncture of the work of the FEMEC-UFU professor-engineer, it is possible to affirm that there is indeed a tendency that his graduate activities superimpose the activities he might develop at the undergraduate level. However, in view of changes on the work system, some professors that already have a consolidated career have chosen to leave the graduate teaching and be active on the research work and on the undergraduate teaching. In this way, these professors believe to be to more loyal to their values and education ideals. There some professors that left the graduate work to seek recognition by working at the coordination level of a new undergraduate course. Moreover, another aspect that appears from our study is that the work of the ―professor-engineerresearcher‖ [in partnership with some industry] consumes most of the time that he could dedicate to his activities at the undergraduate level, and in some cases, at the graduate level. It is important to remember that such ―extra-school‖ work is induced by public bids, reconfiguration of public universities, and the incentive of the PPP s, in a context of increasing demand of both the productive and enterprise sectors for technological knowledge. Also, assuming adminstrative positions and, therefore, participating of the university administration difficult developing teaching activities in the graduate or undergraduate levels. The immaturity or the unpreparedness of students were also considered as factors that render the work at the graduate or undergraduate levels a strenuous task. Finally, in the vision of some professors, the exigencies of the work at the graduate level tend to be considered natural and even justified. Such demands could, in some circunstances, make possible a better sinergy between the two levels of education, graduate and undergraduate. The laboratories [thereby, the practical classes] could be greatly improved. Therefore, more students could be atract to the courses it worth to remember that, after all, students are important inputs for the researches and publications.

The main objective of this work is to prove that the map B defined on F and taking values in B, where F is the set of all continuous functions from Sn to Rn and B is the set of all nonempty closed subsets of Sn, invariant under the antipodal map, which assign to each f 2 F the set fx 2 Sn; f(x) = f(��x)g, is continuous when the topology of F is the topology induced by the usual metric, and the topology of B is the upper semi-finite topology. Considering in F the topology induced by the usual metric, we will have that the finest topology in B such that the map B is continuous is the upper semi-finite topology.

This work scoped to comprehend the experience of the cochlear implant user auditive deficient child‟s family, more precisely to understand its role, identify the changes into the everyday life, describe the strategies which are in between the cohabiting with the auditive deficiency in the childhood, and, to acknowledge the structure, the development and the family functionality. This research is about a qualitative work having the Symbolic Interactionism and a The Grounded Theory as theoretical and methodological references respectively. To obtain the data we used genogram, ecomap and consented interview semistructured. Nine families participated in the study, reaching a total of 32 participants. The data analysis permitted us build up seven thematic categories: In seeing an idealized future pulling down, Seizing to the hope of implanting, Battling for results, Facing hard moments, Recognizing that she doesn t face it all alone, Learning to overcome, and Having the life rescued by the cochlear implant, which compose the phenomenon: MOBILIZING TO RESCUE THE FAMILY LIFE THROUGH THE COCHLEAR IMPLANT, by which we comprehend this experience. We learnt that the implant altered the path of their lives and it permitted the family resignify the deafness. It is like a passport which makes possible to the child to live in the world with less difficulties, more independency and autonomy, and with more chances of a personal, social, academic and professional future of success like any other child. The results show us that it is indispensible to make the family participate actively into the child‟s linguistic development and let the communication skill be worked, for its role as protagonist in the process of rehabilitation and constant stimulation showed us to be evident. We expect that this work may help and conduct the professionals involved in the area to care for the families of auditive deficient children, specially the implanted ones, taking into account the familiar perspective in its professional practice. And we make an invitation to the Nursing Field to approach those families into the reality and to the complexity of the experience of the cochlear implant in the childhood, in order to appropriate the knowledge of this issue, act and exercise their practices.

Leaf-cutting ants are considered one of the main pests that affect Brazilian agriculture. To control this pest are employed, most often, halogenated, sulfurous and phosphorus compounds. However, the continued use of these compounds leads to problems such as the emergence of resistance by insects, soil and underwater contamination e most of them affect many non-target species, may cause environmental imbalance and thus raising the needed of search for new compounds that are more selective and less damaging to the environment. From this perspective, the present work presents a phytochemical study of the specie Virola sebifera and evaluation of the insecticide and/or fungicide potential of the crude extracts, fractions and isolated compounds against the leaf-cutting ants, Atta sexdens rubropilosa, and its symbiotic fungus, Leucoagaricus gongylophorus. One of the techniques employed to the phytochemical study was the high-speed counter-current chromatography and it was confirmed the efficiency of this technique and the importance of choosing a suitable biphasic solvent system for the desired separation. In this work were isolated and/or identified three acylresorcinols, four lignans and five flavonoids, being all the flavonoids the first time reported for this specie. From the biological tests with leaf-cutting ants, it was found that the methanol extract of leaves of Virola sebifera and theirs fractions showed insecticidal activity as a result of the synergistic effect of their chemical composition. The bioassay with the symbiotic fungus, Leucoagaricus gongylophorus, revealed great fungicide potential of the isolated lignans, mainly the lignan (-)-kusunokinin, which exhibited 100% of inhibition of mycelial growth.

The growing demand for information along with a higher education policy effectively amounted to graduate to a higher level, changing its focus from simple teacher trainer for studies in applied research, especially in science and technology. Given this scenario it was found the need to create mechanisms that can assess the progress of science itself and this process was through the investigation of scientific production. Were created methods and tools to quantify and assess the scientific literature and among the many we can highlight bibliometrics. Through bibliometric analysis tools is impossible to quantify data and identify patterns. The work is justified by the absence of evaluation research in the field of history of education and also tries to fill a gap in studies that use theses and dissertations as an object of study. It aims to continue the studies aimed at mapping the area of education in Brazil, and identify what else has been researched, analyze bibliometric indicators and reflect on the distribution of subjects, represented here by lines of research offered in the country. This case study will be exploratory and explanatory because it aims to deepen understanding of the reality of trying to explain why problems. The research is given by the theses and dissertations that are inserted in the CAPES Theses Database. Underscore the role of CAPES as one of the main articulators of the evolution of graduate education in the country. As a tool of analysis used the Vantage Point software, which can transform files in TXT format a list divided into categories, which facilitates the processing and data analysis. Following this line of research we want to better understand not only the course of history in the area of education, but the area of education as a whole. It was possible to identify certain patterns within the scientific theses and dissertations, for example, major themes, key words being used, the main areas of knowledge and historical periods. We also collected quantitative data about type of work, higher education institutions, year, gender, funding, among other things. Thus it was possible to draw a general picture of the current stage of research development in the history of education, with everything and can serve as basis for further studies.

The theme of solidary economy has gained increasing visibility in recent years. The solidary economy presents itself as a resistance movement to the process of precarious living conditions of workers and has its theoretical basis under construction. The solidary economic enterprises, initially presented as a timid reaction of workers to unemployment and deterioration of labor relations, have proven an efficient generator of work and income, allowing the continuity of their collective activities, with relative perspective of survival. The solidary economy has as one of the key factors for its development the implementation of public policies. Experiences of associations and cooperatives of collectors of recyclable materials have revealed a strict relationship between state and solidary economy. The main objective of this text is analyze if the dynamics in relations between public policies and the experiences of cooperatives workers on selective collection occurs in the sense of building workers autonomy or dependence. This dynamic is analyzed from four experiences of associations / cooperatives of collectors found in the literature and a case study held at the Cooperative Acacia, in the city of Araraquara. Although there are difficulties in notice values of self-management and autonomy in the studied cooperatives, these actions have provided better conditions of work and life of the collectors in comparison to their previous work activities, providing access to social rights by the strengthening of the claims capacity.

The Brazilian environmental education is multifaceted, consisting of various politicalpedagogical conceptions. According to this background, the environmental educator chooses what ideas are best suited to his or her ideals of society and environment. This research is based in ideals of an egalitarian society, in which the social relations are marked by respect to all forms of life and by equal rights and opportunities for all the people. In this sense, the research had as it purpose to offer more possibilities to actions in the area of environmental education to suggest the concept of dialogic learning in order to increase the use of critical environmental education. At last, it discusses theoretically the possible contributions of dialogic learning for environmental education using the methodology of bibliographical research. The study included surveys of the main references in the Brazilian environmental education and learning dialogic and analyzed them in order to present their similarities and potential contributions of dialogic learning for environmental education. At the end of the analysis, we conclude that many of the assumptions of the dialogic learning are present, even though they are scattered, in different conceptions of environmental education, which is based on the principles of dialogic learning and may have its horizon expanded and make their criticality and the search for social transformation and environmental preservation stronger, suggesting concrete directions so it can be socially built.

The electrochemical detection of bisphenol A (BPA) by differential pulse voltammetry (DPV) using a boron-doped diamond (BDD) electrode was developed. A 0.5 mol L 1 H2SO4 solution was used as supporting electrolyte and the DPV parameters (modulation amplitude, scan rate, and modulation time) were optimized. The voltammetries presented adequate repeatability and reproducibility, and the obtained analytical curve (range 0.44 5.2 μmol L 1) presented good linearity (R2 = 0.999), yielding a detection limit of 0.21 μmol L 1. For the electrochemical degradation of BPA (150 mg L 1) using a Nb/BDD electrode in a filter-press reactor, the effect of volumetric flow rate, temperature, pH, and current density (j) in a 0.1 mol L 1 solution was investigated. A positive effect of volumetric flow rate and temperature increases on the COD removal was observed; the pH did not present a significant effect (thus, its value was fixed at 6). By determining the mass-transport coefficient of the system, it was possible to obtain the value of jlim (12 mA cm 2). Thus, for j > jlim, in the absence of Cl ions in solution, the DQO decay was typical of a mass-transfer limited process, while for j < jlim a behavior typical of a charge-transfer limited process was observed. In terms of electrolysis time, the best condition was for j > jlim, whereas in terms of instantaneous current efficiency the best condition was for j = 6,5 mA cm 2. In the presence of Cl ions in solution (1.5 g L 1) using 30 mA cm-2, a significant improvement in the electrolysis time necessary for 90 % COD removal (65 min) was observed due to the electrogeneration of species such as HOCl and OCl (predominant active chlorine species at pH 6); for j = 6.5 mA cm 2 no improvement was observed, but the best average current efficiency was attained (58 %). Determinations of COT decay, in the presence and absence of Cl ions in solution, using 30 and 6.5 mA cm 2, presented characteristics similar to those of the COD decay under the same conditions. Compared to other electrodes (Ti-Pt/β-PbO2 and RuTiO2), both in the absence and presence of Cl ions in solution, the performance of the Nb/BDD electrode proved to be superior to those of the others. Using a TiRuO2 electrode, significant COD reduction was attained only in the presence of Cl ions in solution.

La production discursive pendant la période de la dictature militaire au Brésil (1964-1985) a présenté des particularités qui déterminent des transformations réglées par le majeur ou le mineur degré de répression pratiquée par le régime militaire. Il est ainsi possible de partir d une division temporelle de la période en trois phases, selon les études de Gaspari (2002a, 2002b, 2003, 2004) la dictature embarrassé, la dictature complètement ouverte et l ouverture lente et graduelle et observer, à partir des deux derniers moments, qu il y a un mouvement qui va de l hégémonie du discours politique à l hégémonie du discours médiatique. Il s accentue ainsi des marques qui conduisent à des transformations dans l ordre du discours, en passant d un champ discursif qui privilégie le doctrinaire, marqué par le texte verbal, par rapport à un autre qui se soutient sur la construction de mémoires et l émergence d un texte syncrétique. Par conséquent, c est sur ces deux moments que notre travail se développe, en proposant l analyse de textes de différents genres du discours (le doctrinaire, le mémorialiste, le journalistique) produits parfois par des sujets politiques parfois par des sujets du média. En nous basant sur l Analyse du Discours provenant des travaux de Michel Pêcheux avec son Groupe en articulation avec les études de Michel Foucault, les analyses sont faites par le collationnement de séquences discursives appréhendées dans son caractère syncrétique en révélant aussi le passage d une société répressive à une société médiatique que la négociation d identités produites par la gauche. En effet, en reprenant la production de sens de ce moment de l Histoire du Brésil, nous proposons la réflexion sur l action discursive de sujets qui ont produit contremots dans une société où certains discours étaient interdits. Ces discours expriment aussi les mouvances dans les formes de résistance et les transformations inscrites dans les discours politiques et de la politique. Ainsi, le but de notre investigation est de comprendre les transformations et les mouvements qui se sont produits en relation avec des conceptions de gauche, la charge sémantique imputée à ce terme en différents époques et la négociation par une identité qui englobe les nouveaux groupes en formation. Alors, on voit comprendre la transition d une phase de grand répression dans laquelle se vérifiait la primatie du discours doctrinaire à une phase d ouverture politique qui avait comme principe fondamental le retour des récits et la grande valorisation des images par le média qui transforme la politique en spectacle.

Researchers have made great efforts on building effective teaching methodologies for learners with diverse repertoires. In this direction, a group of behavior analysts developed a computerized teaching program that has been widely used in laboratory context and has been recently used in school context. Satisfactory results have been obtained on teaching reading and writing basic skills in both contexts. The program, named Aprendendo a Ler e a Escrever em Pequenos Passos (ProgLeit), was developed based on literature on the formation of equivalence classes of stimuli. It has some of the features established as favorable for learning to read by anyone: speed and degree of difficulty are individually programmed and constant feedback is provided to the performance of the learner. Considering the positive results in controlled environments and school situation, it was possible to extend the controlled use of the teaching program to broader contexts, such as the student s residence. The application of the program in home context by relatives or families trained to monitor and record the sessions created the opportunity to benefit a greater number of children. This study evaluated reading learning by children with intellectual disabilities when trained on the tasks of Module 1 of ProgLeit by their relatives or families in their homes. Concomitantly, the behavior of relatives as ProgLeit monitors was evaluated. For this purpose, a computer with the program was provided for relatives for the duration of Module 1 application. The researcher had trained and supervised the relatives to provide constant monitoring and evaluation of results. Six students from a special school participated in this study, among which five have completed Module 1. Single subject design guided data analysis. Five out of the six students went from zero performance and less than 20% accuracy in reading words printed on pre-test for average performance in the pos-test was near to 89.3% for trained words and 52% for generalization words. Furthermore, they required a reduced number of sessions of each step to reach the learning criteria along the exposure to the procedure. These results replicated those obtained in studies conducted in laboratory and school settings with the same teaching program. The behavior of relative members as monitors was evaluated in terms of providing cues and application frequency. The number of cues provided by them decreased as the student reached the learning criteria in each step, showing greater efficiency teaching program to control the response of the learner. The control of some environmental variables related to the program application such as the local conditions where it is applied, the monitors training and the type of cue provided by them during the application may be important to obtain results even more promising for students with intellectual disabilities. The results indicate that the program application by relatives in the residence of the participants may be a promising learning condition for this population. Furthermore, data showed evidence of the generality of ProgLeit efficiency in other contexts as well as laboratory and school context.

Educative Social Skills (ESS) is an integral concept of the field of Social Skills. The ESS are defined as those intentionally aimed at promoting development and learning of the interlocutor in the formal or informal situations. A repertoire drawn from ESS allows the teacher to use teaching strategies that facilitate interaction between learners, and it carries out activities that identify the expression of emotions and appropriate models of social behaviors, besides having the opportunity to build more adaptive behaviors of students as take initiative, cooperate with colleagues, giving feedback, fight for your rights, express feelings, to deny requests, empathize and others. The objective of this research was to determine which importance is given by teachers for social skills for working with students without or with special educational needs. The study gathered 60 teachers of Primary I and II of private schools in the state of Sao Paulo who answered a protocol for characterization and a questionnaire on Educative Social Skills in which to assess your grade on a scale of one to ten, assessing the importance they attach to each of the subclasses of ESS for their performance at work with students with or without special needs. All teachers considered the Class Monitor Positively as the most important of all. When teachers were divided into two groups: one that has or has had students with special educational needs and one that did not, those students with special needs consider Classes Set boundaries and Discipline more important than those without special educational needs pupils. And in this class, the subclasses Describe/justify undesirable behaviors and Behavior changes were considered more important for these teachers. For teachers who have students with special needs, the subclasses were evaluated as less important: Arrange the physical environment, Paraphrasing, Summarizing conduct issued; Stop behavior, Request information and express agreement. Since the subclasses that these teachers were considered more important: Arrange materials; Mediate interactions; Present goals, Establish relationships between antecedent and consequent behavior; Call to preestablished norms; Commend and encourage. This research has allowed the identification of key special educational needs reported that teachers reported are the most important for working with students without or with special educational needs. The high degree of importance that teachers attributed to the special educational needs suggests that the group participating in this research is sensitive to uncertainties in educational falling pupils with special needs and importance of the ESS for their performance in everyday situations at school. The identification of this information will enable future studies broaden this analysis to correlate teacher reports with the observations of their performance in the classroom.

This paper has as objective to understand how the National Policy of Technical Assistance and Rural Extension (PNATE) comes to the farmers of the family farming. This policy was prepared in 2004 and was celebrated by the support sectors to the family farming, because it meant a disruption with the previous extensionist model, which enjoyed the land concentration on one side, and the producing inputs companies for agriculture on the other, with several damages to the family farming. In this paper, we adopt the case study methodology, in which we observed the Empresa Matogrossense de Pesquisa Assistência Técnica e Extensão Rural (EMPAER) and farmers from the settlement Antonio Conselheiro. 187 questionnaires were applied to the settlers, as a sample of the universe. The research concludes that, if from one hand, the policy advances in favor of the family farming, on the other hand it is far from the goal of making the family farming a dynamic component of household food production chain.

Many people with intellectual disabilities have been deprived of experiences of physical activity, leisure, culture, among others, throughout life, by no offering programs and the historical process of repression in society. The deprivation of motor experiences may generate insufficient learning and development of fundamental motor skills, essential for the satisfactory implementation of activities of daily living, from anyone. Consequently, these conditions can affect your quality of life. Therefore, this research aims to develop, implement and evaluate a program of regular physical activity in physical education classes, for adults with intellectual disabilities, checking possible changes in the ability to walk, run, sit, stand, jump and balance held by these people. This research has described an institutional reality, configuring it as a research-action, involving the participation of adult learners with intellectual disabilities and their parents or guardians, an intern at the Physical Education course, in addition to the researcher. Results were obtained from interviews with those responsible for the students, the analysis of field notes, individual sheets of evaluation of activities, lesson plans and assessment tests of motor skills. The data have to see that there was significant improvement in student performance in relation to motor skills worked in firearms. However, much of this success, the program has provided noticeable improvement of emotional and relational skills of participating students, emphasizing the spirit of cooperation that blossomed between them from the proposed activities. Thus, one can assume that rises and settles from there, self-confidence, one of the requirements for independent living. It is recommended that a new thinking about the need for greater encouragement of the development and implementation of programs for people with disabilities, think about this, supported by the appropriation of the conditions that have to do during the execution of this research and that resulted in an intense and meaningful transformation for all involved in this research.

The development of bismuth film electrodes (BiFE) and minissensors/BiFE for application to the development of electroanalytical procedures for determination of atrazine, Diquat and Paraquat using voltammetric techniques as square wave (SWV) and differential pulse (DPV) is reported in this work. It was chosen to combine the working electrode (BiFE), pseudo-reference (silver glue) and counter (copper) in the same bracket for easily locomotion of the electrochemical system for field analysis. Copper plates of printed circuit were used as substrate and nail polish was used as an electrical insulator to limit the active area. Thus it was possible to make a minissensor with low cost. For the first procedure developed it was determined atrazine in natural waters using BiFE and DPV after the optimization of experimental conditions was obtained an analytical curve linearity for the range from 6.6 x 10-7 to 2.0 x 10-5 mol L-1, with a limit of detection of 1.4 x 10-7 mol L-1. Subsequently, parameters of the SWV technique for determination of Diquat in water samples were studied using BiFE and minissensor/BiFE and the linear correlation was obtained for a concentration range from 1.9 to 5.6 x 10-7 x 10-6 mol L-1 and from 1.9 x 10-7 to 9.3 x 10-6 mol L-1 respectively, and the limit of detection obtained were 8.7 x 10-8 mol L-1 and 8.9 x 10-8 mol L-1. Finally a procedure was developed for the determination of Paraquat using BiFE and minissensor/BiFE by DPV. For the BiFE a linear relationship was obtained for the concentration range from 6.6 x 10-7 to 4.8 x 10-5 mol L-1, with a limit of detection of 9.3 x 10-8 mol L-1. After being selected the best experimental conditions for minissensor/BiFE, it responded to a linear concentration range from 6.6 x 10-8 to 3.9 x 10-6 mol L-1 with a limit of detection of 1,2 x 10-8 mol L-1.

This work reports the synthesis, characterization and investigation of the electronic properties of heterocomplexes formed by cobalt(II) tetrakis(N-methyl-4- pyridyl)porphyrin (CoTMPyP) and cobalt(II) 4, 4 , 4 , 4 , tetrasulfophtalocyanine (CoTsPc) in solution and thin films. Spectroscopic titrations were performed using solutions of the CoTsPc and CoTMPyP macrocycles, and the heteroaggregates stoichiometries were investigated using Job s method. The Job s plots pointed to the formation of supramolecular arrays containing higher proportions of CoTsPc. It was possible, for the first time, to isolate species formed in solution by changing the medium s dielectric constant. After characterization of the isolated species, it was verified that, despite the different stoichiometries, only one heterocomplex was formed, composed by two molecules of CoTsPc in terminal positions and one CoTMPyP molecule. The triad was characterized by mass spectrometry and UV-vis and i.v. absorption spectroscopy. Strong interactions between the charged substituent groups of the CoTsPc and CoTMPyP macrocycles were observed, in addition to the significant changes on the macrocycles electronic levels, due to the coupling of the electronic densities in the face-to-face array. Thin films containing the precursor macrocycles and the triad were grown using the Layer-by-Layer (LbL) technique. LbL films of CoTsPc with poly(allylamine hydrochloride) (PAH) polymer and CoTMPyP with poly(styrenesulfonate) (PSS) polymer were grown up to 30 bilayers. The CoTsPc and CoTMPyP macrocycles, in the mixed LbL films, behave independently, without formation of heteroaggregates during bilayers deposition. Triad s LbL films, using PAH as polyelectrolyte, were also obtained up to 15 bilayers. Cyclic voltammetry measurements of the LbL films demonstrated the coupling of the macrocycles electronic densities in the triad, through changes in the redox potential of both rings and metallic centers.

This study aims to analyze the impact of services developed by the Center for Educational Support Services for People with Visual Impairment of Maranhão (CAP-MA) in the period 2001 to 2008, based on documentary surveys, observations of services provided for the visually impaired and the general community and in conversations among students, responsible students, and professionals (teachers, technicians of the CAP). The CAP-MA is a federal initiative in partnership with the State of Maranhão and aims to offer a quality educational services to students with visual impairments. The study included 28 teachers from the CAP, ten students with visual impairments, five technicians, responsible for seven blind students and 30 course participants from the community. Were used to collect data three instruments: observation script, documents with information on professionals and students and interview guide. Data collection followed the ethical and methodological referrals needed. For the analysis of data treatment was used qualitative content analysis through the categories captured in different sources. The results showed that both teachers, students, parents, coaches and community in general value the services provided by the Support Center. The teachers feel satisfied with the dynamics of services developed and recognize that the CAP has grown with every passing year. Admitted that it still needs constant deployments because the demands are manifested differently each year. Technicians in turn see the actions of the CAP progress are acquired with commitment of all involved in the process. Working with the heads of students and the proposal to list them on the labor market has been very important nowadays. The family showed feel satisfied with the actions for their children and their families. Students appreciate the new shares of the CAP over the other contest some services due to length of service for those who are placed in regular education. Considering all that has been treated in the results can be inferred that the work of the CAP in general, has brought good results for the population of visually impaired people from across the state. Progress was made over the years, not only the quality of care for students with visual impairments, as well as professionals and the wider community. Partnerships and dissemination has facilitated the recognition of the importance of these services. The State Government is fulfilling its responsibilities as a partner in the federal government, signed since the implementation of the CAP in 2001, the State of Maranhão. Finally, it is important to value the suggestions of professionals, students, family and community at large about the progress of the Center's services to detect, through the.

The high market volatility associated with the search for operational efficiency, the occurrence of risk events and the complexity of operations in enterprises, increase the vulnerability and the risks of disruption in supply chains. The consequences of such disruptions are enhanced by the increasing integration and synchronization of operations, since disturbances in an organization immediately affect the rest of the chain and, consequently, its resilience, not being enough a competition based on cost and quality. In this context, flexibility and supply chain risk management emerged as ways of building resilience, being the objective of this study, to identify how organizations of an automotive supply chain apply practices related to such concepts to increase their resilience. Interviews with directors of three automotive companies were conducted in order to capture the view of professionals directly involved with the research problem studied. The study showed that, beyond the lack of convergence on these subjects in literature, in organizations, there is limited knowledge about them, as well as difficulty implementing associated practices in a structured and integrated way between the areas of the company and supply chain members. Even the centenarian organizations evaluated, do not have a strong culture in supply chain risk management and formal or integrated application of methodologies and practices associated with flexibility and risk management, being their view and approach generally reactive. Beyond the scope of the research, this study can be used as a knowledge base on the conceptual subjects, since it was created a relationship diagram involving the concepts presented, and as a reference for the practical implementation of initiatives associated with them for building resilience in organizations and chains.

Pregnancy causes considerable physiologic, hormonal and anatomic changes in women that may affect the lower limbs and trunk movements, lead to instability of postural control and increased risk of falls, causing a direct impact on mother´s health and quality of life. We conducted three studies to examine the changes in static postural control (STUDY I), in dynamic postural control (STUDY II) and the relationship of these changes with quality of life (STUDY III) of 13 pregnant women during the gestational period (G1, G2 and G3), and a control group of 29 non-pregnant women. For static postural control assessment, a force plate (Bertec®) was used and to assess the quality of life was used the WHOQOL-Bref. In STUDY I posturographic tests were applied in four still standing positions, for three trials, with a combination of different visual conditions (eyes open - EO/eyes closed - EC) and support base configurations. The variables analyzed, derived from the center of pressure (COP), were statokinesigram, displacement amplitude, displacement velocity and sway frequency. In STUDY II were analyzed variables of ground reaction force during the stance phase of gait: time and value of the first peak (P1), second peak (P2) and the valley of the vertical component; time and maximum and minimum value found in the anteroposterior horizontal component (max Fy / min Fy) and the difference between the maximum and minimum values in the mediolateral horizontal component ( max min Fx). And in the STUDY III we used data from the first two studies, plus the assessment of quality of life of pregnant women. The results demonstrate that, early in pregnancy, the woman's body seems to be already adapted for postural control, probably due to hormonal factors, and during the trimesters there was a decrease in postural stability. Compared to the control group, pregnant women had larger areas, an increase in the amplitudes and velocities of COP displacement, more time in the first phase of weight acceptance, lower values of peak 1 and 2 of the vertical component and lower maximum and minimum values of anteroposterior horizontal component of ground reaction force, possibly indicating a reduction in speed and thrust of the gait. With respect to quality of life, the physical domain was the most affected in the first trimester, with lower values mainly during late gestation.

The influence of temporal and spatial gradients on the physical and chemical variables, phyto- and zooplanktonic communities were evaluated in two shallow urban reservoirs with different trophic state from Pernambuco State, Northeast Brazil. Monthly samples were taken during a complete hydrological cycle (March 2008 to February 2009), considering a point of study in the Prata reservoir and two points in the Apipucos reservoir, always between 08:30 and 11:00. Biological indexes for planktonic communities were used to understand better the effect of water quality conditions on biota. High levels of eutrophication were observed in the Apipucos reservoir. In the Prata oligotrophic reservoir, the pH was ever considered acid. The values reported for physical and chemical variables and chlorophyll a reflected the trophic state of each system. Higher values for richness, diversity, density and biomass of plankton communities were recorded in the Apipucos reservoir, especially for phytoplankton. However, phytoplankton evenness was higher in the Prata reservoir, while for zooplankton the values obtained in both reservoirs were very similar. Rainfall governed the temporal dynamics of the analyzed variables, and the seasonal variation exerted great influence, especially in the Apipucos reservoir. Aquatic macrophytes seeming to exert a prominent role in the ecological processes in the studied environments. In general, vertical homogeneity of water column was evidenced in both reservoirs, probably caused by the wind action. In Apipucos reservoir, the point 2 showing the higher phosphate nutrient levels and more severe deterioration conditions of water quality, in relation to point 1. Despite the low densities recorded for the toxic cyanobacteria species present in the Prata reservoir (Dolichospermum sp. Geitlerinema amphibium and Lyngbya spp.) it is highlighted the need for a periodic monitoring of population development of these organisms. It is suggested that the zooplankton community do not exerts significant grazing pressure on phytoplankton in both reservoirs, indicating the predominance of the bottom-up on the top-down effect in the control of planktonic populations. The biological indexes for planktonic communities were effectives in assessing water quality in both reservoirs, emphasizing the potencial of these organisms in the characterization of environmental conditions of aquatic systems. Overall, the hypotheses tested were confirmed, especially regarding the influence of trophic state on the physical and chemical variables, composition, diversity and structure of phytoand zooplankton. However, it is noteworthy that seasonality had greater influence in the Apipucos eutrophic reservoir, while in the Prata reservoir only few variables presenting a significative seasonal variation.
