False memories can be defined as recollections that do not correspond to the facts experienced by subjects. Cognitive research have pointed out that the referred phenomenon is, to some extent, determined by semantic relations among stimuli. Based on these studies, behavior analysts have proposed experimental analogous of false memories using the stimulus equivalence paradigm to establish symbolic relations. The current master’s thesis was composed by one preliminary study and two main studies. The preliminary study aimed to assess the valence and arousal of pictures depicting facial expressions, and to select the meaningful stimuli that were employed on the class formation procedures of Studies 1 and 2. Study 1 aimed to analyze possible effects of emotional stimuli with different valences (positive, neutral and negative) on the occurrence of false memories. For this purpose, a systematic replication of Aggio’s (2014) Study 3, using lists of symbolically related stimuli through the stimulus equivalence paradigm was carried out. The main experimental manipulations of Study 1, in the present thesis, were the control of valence and arousal magnitudes attributed to the emotional stimuli; the use of emotional stimuli in the class formation procedure, which contained the unrelated distracting stimuli; and the randomization of list order presentation. Study 1 was structured in four phases, which encompassed 1) the establishment of six equivalence classes; 2) a false memories test with a memorization task and a recognition test, held one week after the beginning of Phase 1; 3) class merger and maintenance test, and 4) stimuli assessment through a semantic differential. Results showed that the false memories effect, under symbolic control, occurred only in relation to the positive stimuli list. It was hypothesized that the stability of the equivalence classes was an intervening variable. In order to verify the aforementioned hypothesis and search for new evidences regarding the effects of emotional valence on the establishment of false memories, a second study was proposed. The Study 2 had the same procedure as Study 1, with the exception of two changes: the reduction of the time interval employed between the first and the second phase, and the insertion of baseline review blocks of the six equivalence classes before the false memories test. These changes were adopted in order to increase the probability that the equivalence relations were stable and strengthened at the moment of the false memories test. Results showed the occurrence of the false memories effect in positive and neutral lists. These results suggest that stimuli with negative emotional valence can reduce the probability of false memories occurrence.

The main objective of this research was to identify, understand and analyze the beliefs, experiences and actions (pedagogical practice) of English teachers who teach in technical courses of an Education, Science and Technology Federal Institute (FI), and guide to the improvement of the English learning-teaching process directed at professional formation programs offered by these institutions (or by others with similar profile). In this sense, we sought to identify and analyze the beliefs, experiences and actions of the participants regarding the specific aspects related to English learning-teaching, such as the student, the teacher, the third parties, the materials and the evaluations, by means of semi-structured interviews, self-reports and class observations, respectively. The guidance proposed by the participants were also surveyed by means of a semi-structured interview. For the collection and analyses of the data, we adopted a qualitative approach. Three case studies were conducted with the foreign language teachers of a FI. The data obtained during the year of 2016 were analyzed based on the Contextual Approach for studying the beliefs, and on the theoretical suppositions regarding the experiences and pedagogy of the post-method. The results point to the fact that the experiences, beliefs and actions of the teachers influence each other in a non-linear manner, in a more complex manner. In addition, it was possible to survey microstrategies for the learning-teaching of languages for the contexts of technical formation at a middle level, which meet the suppositions of a post-method pedagogy.

The present dissertation aims to analyze the relationship between the organizational structure of the Partido do Socialismo e Liberdade (PSOL) and its characteristics. It starts from the premise that the origin of the party focuses directly on the format and organizational aspects that will build it. It seeks to identify the influence of genetic elements of the PSOL, which is born of a kind of internal rupture of Partido dos Trabalhadores (PT) parliamentarians, both in its development and in its political orientation. The específical hypothesis that there is a concentration of power in the party (parliamentary) and organizational arena of the party, in which the elective parliamentarians decide by the caption. Complements the organizational analysis complements the examination of the performance levels of the PSOL and the identification of ideological elements in its parliamentary action with the objective of exploring aspects originating from the party in its development.

This research investigates the current militant frame of the PT and PSDB in Sao Paulo state, comparing them at different moments of their party path: youth and adult militancy – emphasizing the dimension "party on the ground face”. The research aims to fill two gaps of the current literature: first, contribute to the understanding of the profile and to the content of the performance of affiliated people in political parties; second, determine what are the impacts of generational changes in the Brazilian democracy, particularly in relations between young people and democratic institutions, specifically the man effects on internal life of the Sao Paulo's political parties. For this objective, we compared two surveys: one with young militants (respondents with a means age of 24 years) and another with adults (mean age 44 years) and the data obtained at Electoral Court (TSE) regarding the age groups of the members (2008 to 2016) and the age of entry of active members in 2014. The main findings are: aging tendency of both party memberships; disparity of civic resources of members and young members’ vis-à-vis the electorate; predominance of the mobilization by the collective incentives in both surveys. In addition, the relevant impacts of belief systems and internal rules at different levels of mobilization.

This research encompass two studies. The objectives of Study A composed by two steps: Stage 1- In the period of 10 years (2005 – 2014), identify and analyze theses and dissertations produced in Brazilian graduate program with objective of development proposal of Early Intervention Programs for children's development were identified and analyzed to seek main variables studied; and Stage 2: - The proposals of Early Intervention Programs developed that identified in previous stage were characterized and assessed. The Study B described evaluations of Early Intervention Programs after the event of researchers responsible for proposal and execution, as well as continuity of work after conclusion of research. The Study A based on data from the Theses and Dissertations Bank of Brazilian Digital Library (BDTD), whose search descriptors were: early attention, early stimulation, essential stimulation, child stimulation, child development stimulation, early intervention, development surveillance and screening of development. According to two independent judges with pre-defined criteria of inclusion and exclusion, this Study analyzed 25 cases integrally. In step 1, the protocol "Early Intervention Programs Characterization" (PIP) used to systematize information about participants, methodological considerations, intervention characteristics, studied variables, results, limitations and future studies, whose results indicated a predominance of indirect PIPs (13/25) that worked with training and formation of mediators. The presence of children in the PIP varied between forms of individual participation and groups. The mediators of the mixed intervention studies, who participated in PIP, along with children, were mainly parents / guardians. The categories of limitations and / or risks for development: Prevention, Risk and Disability, with a higher incidence of studies in category of Risks. Only one research used an equal control group design and follow-up evaluation was presented in three studies. Ten programs concurred with traditional paradigm and new paradigm, only one study presented characteristics of New Paradigm and the Family-Centered Model. The contexts in which interventions carried out were residences, kindergartens and university. Indirect interventions had a longer duration when compared to direct interventions. The target behaviors / abilities of intervention related to child development and parental and professional training. The results mostly evaluated as positive regardless of intervention type performed. Only three studies indicated non-effective results. 14 studies indicated limitations regarding both research design / procedure and intervention program. Questions raised for future research on methodology, such as longitudinal studies, extension of intervention, extension of sample searched and higher frequency of evaluations. Family demands related to parental / caregiver adherence to intervention programs, parents / child bonding and family / school relationship, and in professional context, knowledge about health surveillance and development surveillance was highlighted. In step 2, the protocol "Evaluation of Early Intervention Programs" (adapted from Mendes, 2010) used to analyze the programs within the community, family, child and intervention program, whose results indicated that community level, 14 studies did not indicate referral procedures, used voluntary or convenience samples. The eligibility criteria for PIPs quite diverse; 18 studies did not mention screening procedures for participation in program; information to families generally provided at beginning of program and it is also possible to inform that IPPs more directed to interests of researchers than to real needs of population. At the family level it can be verified that host interview and presentation the PIP were more frequent than actions that involved planning of support to families. At children's level, studies focused on social life and child autonomy. At PIP level, they showed more frequently performance of a single professional, without specific training; with activity plans that presented some information gaps such as: objectives, materials, teaching and registration procedures; few revisions in intervention proposals observed, with main concern in effectiveness of programs, whose evaluations based on non-standardized instruments. In the Step 1 results indicated that there was indirect predominance of PIPs (13/25) that worked with training, mediator development. The presence of children in PIP varied between individual forms participation and groups. Mediators of mixed intervention Studies, who participated in PIP, along with the children, were mainly the parents / guardians. Limitations and / or risks for development had been categorized: Prevention, Risk and Disability, with a higher incidence of studies in the category of Risks. Just one research used control group design and follow-up assessment presented by three Studies. Ten programs concomitantly met traditional paradigm and new paradigm, just one study presented characteristics of New Paradigm and the Family-Centered Model. The interventions carried out in residences, kindergartens and university. Indirect interventions had a longer duration when compared to direct interventions. The target behaviors / skills of intervention related to child development and parental and professional development. Independent of type of intervention performed, the results mostly evaluated as positive. Only three research indicated non-effective results. 14 studies indicated relative limitations to research design / procedure and intervention program. For future research, questions relating to methodology was highlighted, such as longitudinal studies, extension of intervention, extension of sample surveyed, higher frequency of evaluations. In family context, demands referred to participation of parents / caregivers in intervention programs, parents / child bond and family / school relationship, and in professional scope, knowledge about surveillance of development and health / education integration highlighted. Step 2 results indicated that in 14 studies there were no referral procedures in community analyzes level whose samples were voluntary or convenience; diversified eligibility criteria for PIPs; 18 studies no mention screening procedures for participation in the program; information had been provided in beginning of program for family; it is possible inform that PIPs more directed to researchers interests than real needs of population. In family level, it can verify that foster interview and PIP presentation were more frequent than actions with planning of support to families. In children's level, the studies focused on social life and children's autonomy. In PIP level emphasized more frequently performance of single professional, without specific qualification; activity plans with some gaps information such as: objectives, materials, teaching and registration procedures; few revisions in intervention proposals were observed, with main concern in effectiveness of programs, whose evaluations were based on non-standardized instruments. Study B analyzed posteriori assessment of researchers responsible for proposing and executing the Early Intervention Programs, as well as their continuity after their conclusion. Ten researchers answered a questionnaire with following topics: validity period, institutional support, concomitance between closure of research and program, and assessment of program regarding objectives / focus of intervention, screening procedures and evaluation procedures, family participation, engaged professionals, child development and results obtained vs expected. The results had been indicated that programs lasted up to 12 months; six of them had financial support; closure of the programs occurred concurrently in eight of them; it were positively evaluated by their proponents; it presented questions to be improved regarding theoretical reference, organization and planning of actions to be developed. It can indicate that research involving early intervention presented are important initiatives to deal to early stimulation in children with different risk factors and / or disabilities and producing knowledge in Brazilian context.

SUS (Portuguese acronym for Unique Health System) is a political and organizational formulation for the reorganization of health services and actions, guided by the principles of universality, equity and integrality, but since its creation, it has faced major challenges for its effective consolidation and implementation. In order to meet the health needs of the population, services must be organized in a network based on Basic Attention to access levels of greater complexity. In the search for favorable transformations for the qualification of care, institutional support emerges as a device capable of strengthening the spaces of attention, aiming to modify the forms of health planning and management. The support arises through the need to review the processes of production of care, with the valuation of the subjects involved and the achievement of more democratic ways of doing health. Thus, the present study sought to analyze the practices of institutional support as a device for strengthening health care networks, based on the perceptions of supporters and workers considering the potentialities, challenges and strategies used in the support function. The research was drawn from a qualitative approach, in the form of an exploratory-descriptive case study. For this, the focal group technique was used with supporters as well as workers of supported team who met the selection criteria. Thematic categorical content analysis technique was used for the systematization of the material produced. The research findings point to the need to bond the supporters with the teams to be supported, as well as an adequate time for insertion into the routine of services, to produce organized collectives aimed at new forms of work management. They also indicate the need for appropriation of strategies and tools for the support function, however, in addition to those established in the literature, others can be constructed in the act, in the practice of actions. Moreover, they point out challenges that must be considered and put into analysis, especially those related to hegemonic and vertical managerial issues, in search of transformations of management and attention practices in a proposal to foster co-management, to promote the production of collectives and the autonomy of the subjects Involved with health care.

The orange activity of the State of Sao Paulo is very important for the Brazilian economy due mainly to job creation and for the expressive participation of the orange juice in national exports. In spite of the major growth and the economic stability faced by the Sao Paulo´s Citrus Agro industrial Complex during its consolidation in the mid-1980s, the last 25 years were marked by an economic environment very unfavorable to the orange growers, resulting in the loss of their profitability and the exodus of many producers from the orange production activity. One possible solution is a technological change in the orange orchards, leading to an increase in their productivity reducing the production costs per area. Thus, the producers’ incomes can raise or at least stabilize. Irrigation has been pointed out in the literature as an agricultural technology capable of providing several benefits to orange orchards, from the desired increase in productivity to improvements in fruit quality. However, this technology is still not widespread in the orange orchards of São Paulo. This thesis identify and analyse the determinants of the adoption of irrigation in the orange orchards of São Paulo, using a representative sample of 98 orange growers located in the center-north region of the state. The orange growers of the sample were interviewed using a semi-structured questionnaire and the primary data were analyzed by means of descriptive statistics, hypothesis test and double-hurdle econometric models. According to the results the participation in irrigation courses and in farmers associations, the higher soil fertility of the orange farms, the high dependence on the orange production activity, the use of sophisticated management tools and the access to rural credit affect positively and significantly the adoption of irrigation. On the other hand, the use of contracts in the sale of orange reduces the probability of adoption of irrigation in the orange orchards, since the orange farmers who irrigates sell their production, mostly, to the fresh fruit market through the use of spot market mechanism. Among the orange farmers who irrigates, those who use irrigation in a larger part of the orange area participate in irrigation courses, are very dependent on the orange activity, have a productive structure with less orange varieties, denser orchards, and properties with soils of low fertility. For these producers, the sale of the orange production is mainly done through the use of contracts with the processing industry. This mechanism can promote the necessary safety to intensify the use of irrigation in the properties.

In ethanol production process from hemicellulosic fraction, the use of xylooligomers (XOS) as substrate reduce the contamination risk, favoring its application at industrial scale. Thus, a biocatalyst, containing xylanases, xylose isomerase (XI) and yeast co-immobilized in calcium alginate gel, was developed and XOS simultaneous hydrolysis, isomerization and fermentation (SHIF) process was studied. Firstly, xylanases from Multifect CX XL A03139 (XAS-5), a commercial enzyme preparation, and the recombinant xylanase from Bacillus subtilis (XynA) were selected to compose biocatalyst beads. XAS-5 presented better conversion (78.7%) and higher xylose production in the hydrolysis of beechwood xylan, while XynA showed exclusive endoxylanase activity. The immobilization and stabilization of XynA were performed in chitosan-glutaraldehyde, chitosan-glyoxyl and agarose-glyoxyl. Although the enzyme was efficiently immobilized on all supports, the agarose-glyoxyl-XynA derivative was notable for exhibiting remarkable stabilization under tested conditions (8600 times). Studies of SHIF process were carried out with birchwood xylan, leading to ethanol production (0.160 g/g and 0.092 g/L.h) and xylose accumulation, which indicated XI activity decrease. Further experiments were then performed to to identify possible inhibitors of XI (pH, Ca2+, Mg2+ and xylooligosaccharides). Ca2+ was identified as an inhibitor, while Mg2+ acts as an activator of the enzyme, and both actions are potentiated at acidic pHs. XI is also inhibited by XOS, with a decrease of 31.6% in XI activity in the presence of 7.0 g/L of xylobiose. For this reason, it was decided to evaluate SIF process with a recombinant yeast, capable of expressing XI. In batch runs, GSE16-T18 (T18) yeast encapsulated in alginate gel was capable to ferment xylose efficiently, consuming 40 g/L of xylose in 4 h and producing 14.4 g/L of ethanol, with yield of 0.422 g/g and productivity of 3.61 g/L.h. Calcium alginate gel encapsulation also contributed to protect yeast from the action of inhibitors, such as acetic acid. The encapsulated T18 was able to perform 10 consecutive cycles in repeated batch (yeast extract-peptone medium with 40 g/L of xylose), keeping the same productivity and high yields. It also fermented efficiently sugarcane bagasse hydrolysate, containing 60 g/L of fermentable sugars and high grade of inhibitors. The modified yeast to be more tolerant to acetic acid, GSE16-T18 HAA1, was also studied, exhibiting superior performance in comparison to T18 for hydrolysate fermentations. Continuous experiments were conducted in a fixed bed reactor using the T18-HAA1 yeast immobilized, with different xylose concentrations (40, 60, 80 and 120 g/L) in the feed medium. The reactor was operated up to 15 days, without bacterial contamination, with yield of 0.45 g/g, productivity of 4.8 g/L.h and selectivity of 31 gethanol/gxylitol (60 g/L of xylose in the feed). For the concentrations higher than 60 g/L, the conversion decreased after 4 days of continuous operation, indicating loss of cell viability due to hazardous effect of ethanol when present at 30 g/L or more, as well as limitation of oxygen and nutrients in the system.

The aim of the thesis was to present the effects of LLLT, physical exercise and their association on joint cartilage catabolism in the knees of rats submitted to an experimental model of osteoarthritis induced by anterior cruciate ligament (TLCA) transection. For this, a brief systematic review was initially performed where interventions in experimental and clinical studies with animals were considered. The search was performed in the Medline, PubMed, Scopus, Cochrane databases and by active search in a list of bibliographic references of the articles selected until October 2016. The research was carried out according to the guidelines of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta- Analyzes). We searched the databases with the following terminologies for animal studies: laser therapy and exercise and knee osteoarthritis and animal model. The analyzes of the content of the selected clinical trials demonstrated that LLLT associated therapeutical exercises that can be used to improve pain and quality of life are: resistance exercises and resistance exercises associated with stretching. However, these are not methodologically sufficient to demonstrate improved functionality presenting moderate quality for animal studies and high quality for clinical studies. As the clinical studies included in this systematic review have a high methodological quality, it can be concluded that the therapeutic exercises used by the studies improved pain and functionality in knee OA. However, we suggest experimental studies with animals that may present higher methodological quality to explain the mechanisms of action of therapeutic resources. For this, the second study, investigated the effects of the protocol of resistance exercises and LLLT (associated or not) on the metabolism of cartilage in an experimental model of OA in the knee. Forty male Wistar rats were randomly divided into 4 groups: OA control (OAC); OA and LLLT (OAL); OA and Exercise (OAE); OA and Exercise and Laser (OAEL). The resisted exercise program started 2 weeks after the ACL injury, and were performed three times a week for 8 weeks, totaling 24 sessions consisting of climbing exercises with weights attached to their tails and laser irradiation (two- The results showed that all treated groups had the capacity to modulate some of the aspects related to the degenerative process due to ligament transection, but the association of resistance exercise with LLLT significantly decreased the density of chondrocytes (With or without LLLT) modulated the immunoexpression of IL-1β, caspase-3 and MMP-13. These results suggest that resisted exercises modulate the changes The present work evidences the great need of experimental studies that may explain the clinical mechanisms that favor the use of these resources. In the treatment of patients with OA in the knee.

After verifying a shortage of teacher qualification courses concerning the cultural contents approach conveyed by foreign language teaching and learning, we decided to design a project for teacher qualification course to deepen this subject. The extension course was outlined for foreign language teachers of Public Schools of São Paulo State, on Saturdays, with bimonthly meetings interpolated between online meetings by Moodle’s platform. Using this platform, an initial survey, a final presentation, a self-evaluation, and recordings (video and audio), we should collect data for this thesis. We intended to observe if the theoretical arguments, during the course, about cultural contents, would motivate the reflection of the participants in the course in relation to implicit cultural contents in textbooks, and practical approach of teachers/participants in foreign language classrooms of cultural contents throughout the textbook’s adaptation used by them. Besides that, for further work we outlined research questions. The theoretical foundation helped us for reflection and for discussion of the obtained data. Therefore, using a historical journey (LARAIA, 1986; AUGER, 2000, 2003; DURANTI, 1997), we observe the development of cultural concept that helped us to answer the first research question. And, we focused on the relevance of development of extension course (CANDAU, 1997; AUGER, 2005; IMBÉRNO, 2009), on intercultural education (AUGER, 2005), and on textbook adaptation (PRABHU, 1998; Tomlinson, 2012). These theories helped us to answer the second research question. We followed the interpretativist-qualitative research (MOITA LOPES, 1994) and the research-action. In general, we concluded that teacher’s awareness on cultural contents, developed on extension course, helped them for the adaptation and/or development of foreign language teaching materials in order to approach “cultural potentials”. The activities developed by the teachers motivated the students to research cultural contents, to engage in cultural reflections and to recognize (or not) the other culture.

Introduction: Hip abductor strength has been targeted in rehabilitation programs for patients with knee osteoarthritis, however, as it explains only a small portion of medial knee load, the influence of trunk, pelvis, and hip kinematics in the frontal plane during gait in this population should be investigated. This study aimed to investigate the relationship of hip abductors strength with hip and knee adduction moments, pain and physical function, and trunk, pelvis, and hip kinematics during walking in the frontal plane in subjects with medial knee osteoarthritis. Methods: Twenty five subjects with medial knee osteoarthritis were included in the study. Participants were evaluated through an isokinetic strength test for hip abductors, three-dimensional gait analysis, the WOMAC pain and physical function scores, and walk test – 40m. First, the relationship of hip abductor strength with the other variables was investigated. Second, regression models were used to control the influence of other parameters such as pain, age, gender, severity, walking speed, mass and height. Results: Hip abductors strength explained 17% of contralateral pelvic drop and 21% of hip adduction angle. In addition, hip abductors strength explained 4% and 1% of the variance in the WOMAC physical function score and walk test (40m), respectively. Conclusion: Considering the relationship of hip abductors strength with contralateral pelvic drop and hip adduction angle, specific exercises should be used to improve physical function and the ability of hip abductors to stabilize the pelvis and the hip adduction angle during walking.

The objective of this work was to characterize different fibrous filters after filtration and to evaluate the surface treatment performance of these materials during pulse jet filtration, in the removal of micrometric particles of dolomitic limestone. The filtration tests were performed maintaining the filtration velocity constant at 4 cm/s. The operating parameters of the cleaning media used were 200 ms and 2 kgf/cm2, corresponding to the cleaning pulse time and pressure, respectively. The experimental results were: residual pressure drop, cycle time, retained mass, cleaning and collection efficiency, particle deposition depth, deposited particle size, deposited particle size, permeability, porosity, thickness, roughness and diameter of the fibers of the filter media. Thus, in the comparison of fibrous filters of the same fiber (polyester fiber), the results presented different performances during the filtration due to the different surfaces, with untreated and treated (singeing/calendering and calendering/thermofixation). Untreated surface filters showed higher cleaning efficiency, lower residual pressure drop and increased permeability after fifty regenerations. However, greater wear on the fibers was observed. The fibrous filters with surface untreated showed close permeability values, lower cleaning efficiencies and higher residual pressure drop after 50 filter cycles. In addition, these fibrous filters with surface treated presented higher collection efficiency after the filtration cycles, in relation to the fibrous filter untreated surface. This indicates that the treatment on the surface of the filter medium is indispensable for cycles with long duration using the pulse jet cleaning. In the comparison of polyester and polypropylene fiber media subjected to the same treatment (calendering/thermofixation), the results showed a high cleaning efficiency in the initial cycles, but a reduction of the cleaning efficiency occurred with the increase of the filtration cycles. Furthermore, after the 100 filter cycles, the polyester fiber media showed higher cleaning efficiency, higher collection efficiency, lower particle retention (lower number and lower particle deposition depth), higher permeability, lower residual pressure and lower mass retained after the pulse jet cleaning in relation to PTFE immersion polypropylene media. It was also verified that, the polyester filter media, collected more particles on the surface, characterizing a surface filtration and a lower penetration of the dolomitic limestone particles in relation to the polypropylene fiber filter medium. These results implied that the surface porosity of the filter medium interfered in the formation and removal of the formed powder layer, helping or preventing the cleaning of the filter medium. Thus, it was found that the polyester fiber filter media showed the best operating performance with high collection and cleaning efficiency.

In the past years, computing has progressed in such a way that it has reached many aspects of human life, producing modern elements that accelerate communication among people, institutions and their mutual relations. Among these, there is the school. The changes that happen day-by-day because of computer science may interfere in the educational process. The teacher needs to be prepared so that learning can happen in several ways and spaces. This way, a development on the teacher way of acting is required. Thus, this study was aimed to evaluate an IT training program for teachers who attend students with visual impairment. This research had the following specific objectives: a) to contribute to the teacher‟s appropriation of theoretical and practical knowledge about visual impairment; b) to provide training to teachers so they can operate the computer using basic functions of the main products such as operating systems (Windows, Linux), text editors (Word 2010), the spreadsheets (Excel 2010), presentation applications (PowerPoint), the Internet; c) to provide teachers with training in the use of softwares for the elaboration of accessible materials, screen amplifiers and screen readers, for attending students with visual impairment; d) to verify the performance of teachers in practical activities with students with visual impairment. e) to correlate the performance of teachers in the program with their performance in the practice with students with visual impairment. Twelve teachers took part of this study, distributed as follows: a substitute teacher belonging to the teaching staff of the Instituto Federal Baiano – Campus Guanambi, and 11 from the Municipal Education Network of Guanambi and Caetité who work in Multifunctional Resource Rooms. The data collection site was the Instituto Federal Baiano Federal – Campus Guanambi. For this purpose, the computer laboratory was used with 20 computers, equipped with the necessary software for the execution of the Computer Training Program. The instruments used for the data collection were: an initial questionnaire for checking profile and the level of knowledge in basic informatics, informatics in the school context and informatics in special education; in addition, before and after tests related to the Modules and activity practices. For the data analysis procedures, comparisons were made between the before and after test scores, the teachers‟ frequency in each module and their grades in the activity practices. The course was divided into nine modules: Module I - Basic Computer Skills, within 30 hours; Module II – Application Systems I, within 40 hours; Module III – Application Systems III within, 20 hours; Module IV – Didactic Material Accessibility, within 10 hours; Module V – Accessible Book, within 10 hours; Module VI – Easy Braille, within 20 hours; Module VII – Screen magnifiers, within 10 hours; Module VIII – Windows screen readers within 40 hours, and Module IX – Linux screen magnifier, within 20 hours. The course took place in two academic periods, that is, from October to December 2014, and after the teachers‟ vacations, from February to September 2015. The results showed that the research contributed to the teachers' learning process in order to operate the computer using the basic functions of the main products such as operating systems (Windows, Linux), text editors (Word 2010), the spreadsheets (Excel 2010), presentation applications (PowerPoint), the Internet. It also enabled the teachers to the use of softwares in the elaboration of accessible materials to attend visually impaired students, as well as the use of screen magnifiers and readers to assist students with visual impairment.

A good social skills (SS) repertoire has been identified as a protective factor for problems in the course of child development, especially for children in vulnerable situations, as is the case of institutionalized children. The literature suggests that these children have marked deficits in their physical and cognitive development, compared to children with typical development. As such, one can question whether there are deficits in the socioemotional development of this specific population in terms of social skills and behavior problems. Given that a caregiver is the reference adult for these children, one may also question whether and how well this person promotes the child’s social skills development. The objective of this study was to characterize the social skills repertoire and behavior problems among children in residential care in four institutions located in three medium-sized cities in the interior of São Paulo - SP. It intended to also characterize the repertoire of Social Skills and Educative Social Skills (ESS) caregivers / guardians of these children, as well as investigate possible links between the repertoire of the caregivers and the children. Therefore, we used: the brazilian version of the Social Skills Rating System (SSRS); the Social Skills Inventory (IHS-Del-Prette); The Inventory of Educative Social Skills (IHSE-Parents version for caregivers). Participants were 36 children, of both genders, aged 6 to 12 years and 19 caregivers between 23 and 62 years years of age. The descriptive and inferential statistical analyses showed that: (1) the sample of children had scores below norms in social skills, especially for empathy, with externalizing behavior problems, according to the caregivers, were of above average frequency; (2) caregivers had scores classified as medium repertoire (lower and upper) in social skills and below average in educative social skills; (3) children with higher social skills showed fewer behavior problems; (4) .Children with a higher SS repertoire tended to more positively assess the caregivers’s social educative skills repertoire. (5) No significant result was found among the children's caregivers' and SS's repertoire of Educative Social Skills, as is expected in the case of parents and children; (6) However, in the case of the sample of caregivers from the present study, attention and affection / talk / dialogue skills were the most deficient, precisely those positively correlated with the children's social skills repertoire and present in the repertoire of parents whose children have a broader repertoire of SS. It was hypothesized that possibly caregivers invest more in those children with better repertoire. We discuss, therefore, differences in institutional and family contexts and the importance of caregivers as models of secure attachment and expression of affection towards the child. Such findings can also be considered in the hiring of professional caregivers as well as in the planning of interventions based on ESS. The data also suggest the relevance of interventions aimed at promoting SS of institutionalized children as a way of contributing to their social-emotional development.

The coexistence between man and the animals that surround him has been occurring for the last ten thousand years. Benefits of living with pets have been reported by different areas of knowledge and are related to physical and mental health, being associated with protection factors against depression, anxiety, among others. However, the deficient operationalization of procedures in this area makes it difficult to understand the phenomenon and the scientific production. The present study had as objective to verify the influence of the presence of a rabbit in the tolerance to unpleasant sonorous stimulus. Thirty adults, aged 20 to 34 years (M = 24.3 and SD = 3.2) participated in the study. Participants were exposed to unpleasant sounds by means of headphones coupled to a portable computer in three different conditions. In the Rabbit condition, participants listened to the sound as they watched a rabbit in front of its cage. In the Movie condition, participants listened to the sound while watching a video of the same rabbit inside their cage. In turn, in the Control condition, the participants listened to the sound without distracting stimulus. The time of permanence in the conditions, heart rate and galvanic conductance of the skin were measured, as well as the responses provided to a Scale of Differential Semantics and Visual Analog Humor Scale. The results indicated that participants assessed more positively and remained longer, in seconds, under Film (M = 253.27, SD = 177.99) and Rabbit (M = 255.37s, SD = ± 179.34 ), when compared to Control (M = 172.4, SD = ± 169.9). The data showed that visual contact with the rabbit, physically and also through the video, increased the tolerance to the unpleasant sound stimulus, and also promoted a better evaluation of the participants regarding the stressful situation.

The research analyzes the configuration of the scientific field of educational evaluation in Brazil in the 1980s, starting with the identification of Brazilian authors who helped to construct this field and their respective theoretical contributions on the subject in question. The 1980s were particularly rich for the organization of the Brazilian educational field, especially for evaluation, as it was a period in which the first systematized evaluation experiences for education in the country were formulated (Edurural / 1981, Paru 1983 , Cnres / 1985, Geres / 1986), a period in which considerable knowledge on educational evaluation was also accumulated, and which eventually became the main theoretical references for this subject. With these information, we can discuss the following question: what was the configuration of the scientific field of Brazilian educational evaluation in the 1980s? In order to respond to this questioning, we do a bibliographical and documentary research, associated with the strategies of bibliometric studies and content analysis. This methodology was developed in four stages: 1) Review of the bibliography; 2) Collection and organization of sources; 3) Analysis and interpretation of data; and 4) Presentation of the results of the research. Our hypothesis is that it was in the 1980s that the two main approaches to evaluation that started the discussions about educational evaluation in Brazil began to be outlined: one based mainly on the measurement of results and another that primarily advocates participation in evaluation processes. The results try to make explicit the understanding of the authors analyzed around what is evaluation, of which who are the responsible for the evaluation process, the methodologies defended in the accomplishment of the evaluation processes and of which uses of the evaluation results. The following positions are recurrent in the period: a) the evaluation appears as an inherent activity to the human doing, and therefore cannot be reduced to a mechanical action, since it implies in a relationship of power and negotiation between evaluator and evaluated; b) for the evaluator is required maturity and professional experience to deal with the complex activities that result from the evaluation process; c) the evaluation methodologies do not have a single standard, because they vary according to what is being evaluated and with the expertise of the evaluator; and d) regarding the use of evaluation results, the best option was if they made it public as soon as possible to assist in making decisions that aim at improving what has been evaluated. The research also shows that being in favor of one of the evaluation approaches, besides representing the interests of agents who defend and put into practice fundamentals that guide the understanding about what is evaluation, who should conduct the process, how it should be carried out and the what to do with its results, also reveals the more general concepts that support the very existence of the field. Our conclusion is that the scientific field of educational evaluation in Brazil in the 1980s was in the process of being constituted and its logic of functioning was based more on the complementarity of ideas on the subject of evaluation than on conflicts and competitions.

Theory-of-mind development is a process that has been investigated for decades by researchers from different fields (e.g., developmental psychologists, educators, neuroscientists and psychiatrists). A well-developed theory of mind implies the ability to attribute and understand one's own mental states and those of others, as well as to use this repertoire to explain and predict human behavior. The most significant advances in theory of mind are observed in preschool years and it is exactly at the end of this period that children begin to understand and appreciate humor. The use of humor, in turn, can not only facilitate social interactions, but can contribute to successful ones. Considering the limited number of Brazilian studies on these different aspects of child development, the main goal of the present work was to investigate the relationship between humor understanding and theory-of-mind development. Thirty-seven children, divided into two age groups (twenty 7-year-olds and seventeen 9-year-olds) and 23 adults (comparison group) participated in the present study. The instruments used were: Faux Pas Task (a theory of mind measure), one measure of sense of humor (MSHS for adults, C-MSHSC for children), and a task to assess humor appreciation, which was specifically designed for the present study. The humor appreciation task consisted in presenting participants with four jokes and four comic strips, extracted from children’s joke books and websites on comic strips directed to children. The set of selected jokes/comic strips were rated for funniness using a likert scale. Analyzes revealed differences in the pattern of preferences presented by children and adults in the humor appreciation task. More specifically, children showed more appreciation for the comic strips than adults, but no significant differences were found for joke ratings; the majority of participants rated them as "not at all funny" or "just a little bit funny”. Correlation analyses revealed a significant association between the Faux Pas total score and the MSHS score in all three age groups. More importantly, a correlation was found between children’s performance on the Faux Pas Task and their scores in one of the three C-MSHSC subscales: humor appreciation. Consistent with findings from previous studies, an age effect was found on performance in the Faux Pas Task. Results of the present study should contribute to a better understanding of the relationship between theory of mind and humor understanding, which may be, in turn, useful for the planning of interventions directed to individuals with delays in social cognition, in adverse situations or emotional pain.

The frailty models are used to model the possible associations between survival times. Another alternative developed for modeling the dependence between multivariate data is the use of models based on copulas functions. In this paper we propose two derived survival models of copula of the Ali-Mikhail-Haq (AMH) and of the Frank to model the dependence of bivariate data in the presence of covariates and censored observations. For inferential purposes, we conducted a Bayesian approach using Monte Carlo methods in Markov Chain (MCMC). Some discussions on the model selection criteria were presented. In order to detect influential observations we use the Bayesian method of cases of deletion of influence analysis based on the difference ^. Finally, we show the applicability of the proposed models to sets of simulated and real data. We present, too, a new survival model with bivariate fraction of healing, which takes into account three settings for the latent activation mechanism: random activation, first activation and final activation. We apply this model to a set of Direct Credit loan data to the Consumer mode (DCC) and compare the settings, through Bayesian criteria for selection of models, which of the three models best fit. Finally, we show our future proposal for further research.

Maize is one of the most cultivated cereals in the world and it is among the most important cereals for the consolidation of the production chains of meat, eggs, milk and derivatives in organic system, being one of the main components of the rations. However, there is still little information about the performance of cultivars and quality of maize seed produced in the organic this system. The present work aimed evaluate the performance of maize cultivars in the organic system, as well as the physiological potential of the seeds produced. The experiments were conducted between December 2015 and October 2016. The first experiment was accomplished in the 2015/2016 harvest in an experimental area conducted in the organic system for eight years, located at the Federal University of São Carlos, UFSCar, Agrarian Sciences Center, CCA, in Araras county, SP.Therefore, this study seek to rate the performance of commercial cultivars (improved and hybrid varieties) and local corn varieties in organic system, as well as to analyze the physiological quality of the produced seeds.The experiment was conducted in 2015/2016 crop, conducted in a eight-year organic system experimental area, placed in Universidade Federal de São Carlos (UFSCar), Centro de Ciências Agrárias (CCA), in Araras county, São Paulo. The experimental design used was a randomized blocks with seven treatments and four replications. Were tested three commercial varieties of corn: (AL Avaré, AL Bandeirantes and AL Piratininga), two hybrids (P30F53 AND 2B587) and two open pollinated variety - OPV (Santa Rita 1 and Santa Rita 2). The evaluated agronomic characteristics were: plant average height (PH), stem average diameter (SD), plants stand final(FS), average number of row per spike (NRS) average number of grains row (RGN) and average number of spike grains (SGN) average number, weight of 1000 grains (M1000), Falker chlorophyll index (FCI) and grain productivity (PROD).Also evaluted the leaf content nutrients N, P, K, Ca, Mg and S in cornmaize, the infestation rate (IR) e diseases severity of the spikes (DS) and the armyworm(Spodoptera frugiperda J.E. Smith) susceptibility. The results were submitted to analysis of variance and the means grouped by the Scott Knott test at a 5% level of significance. The second experiment was conducted at the Laboratory of Plant Production and Forest Resources of the CCA, UFSCar in the municipality of Araras-SP. The experimental design was a completely randomized, 7 x 2 factorial design with four replications. The first factor was the seeds of the maize cultivars and the second was the storage time of the seeds in PET bottles (zero and 90 days). For evaluete the physiological potential of the seeds were evaluated: weight of 1000 seed mass, first germination count, germination test, first germination count after, accelerated aging test and the emergency speed index. The results were submitted to analysis of variance and the averages were grouped by the Tukey statistical test, at the 5% level of significance. The hybrid 2B587 presents the best performance in organic farming, fact that is probably related to their drought tolerance, foliar nitrogen content and Falker chlorophyll index. It's important evaluate their perfomance in another crop because the perfomance should be the intrinsic characteristics of each grow crops and their environmental interaction. The seeds produced in organic system presented high vigor and percentage of germination, even after the storage in PET bottle, which maintained the quality after 90 days of storage.

Magnesium is considered a promising candidate in applications of storage hydrogen in the solid state, due, among other factors, to its low relative cost and high gravimetric capacity (7,6 wt%.). For magnesium, the use of transition metals as additives may show great improvements in the kinetics of hydrogen absorption/desorption. Different additives can have different functionalities, for example, reducing the energy barrier for H2 adsorption and acting as a heterogeneous nucleating agent in the kinetics of phase transformation. In this research, the main effects of the use of zirconium (Zr) as an additive of the magnesium for the purposes of hydrogen storage in bulks produced by rapid solidification in melt-spinning furnace and cold rolling were studied in detail. Basically, structural characteristics were related to the behavior of absorption / desorption. The alloy produced by cold rolling showed behavior of activation and absorption similar to the pure Mg which was produced by the same route. For the route processed by melt spinning, the use of zirconium as additive has presented a deleterious effect on the activation. However, after activation, the kinetics of absorption exhibit behavior similar to pure Mg. The activation had significantly improved after mechanical or thermal processing, however, the structural characteristics that permeate this effect still have a lack of studies. For both process route, the desorption kinetics presented excellent results, reducing the complete reaction in a few minutes. With the results obtained it is possible to conclude that the use of zirconium as an additive in magnesium alloys has no beneficial effect on absorption. In the other hand, the desorption is extremely attractive. After exposure to air, it was verified that both compositions presented formation of contaminants on the surface and this made the activation a difficult way. However, this effect was more latent in pure magnesium.
