    The maize intercropped with green manures, especially Fabaceae provide in addition to soil protection, nutrient recycling, N deposition through biological fixation and control of spontaneous, also contribute to the increase of natural enemies, playing an important pest control insects. Such benefits of green manures are extremely important for organic corn production. With this work proposed to investigate the effects of Crotalaria spectabilis arrangements in the canopy insect community and corn production components grown in a consortium.The experimental design was a randomized block with five replications. Treatments were corn consortia with C. spectabilis: (CL) - C. spectabilis seeded on the same lines of corn; (EC) - C. spectabilis seeded corn rows; (CLE) - C. spectabilis sown in rows and lines of maize and a control (M) - Single corn. For the community canopy insects evaluated the similarities and major components associated with different arrangements C. spectabilis the consortium as well as the severity of damage caused by H. zea and S. frugiperda in maize. To evaluate the agronomic characteristics of corn evaluated were: plant height (m), ear height, dry weight of the stem (MSC), leaves (SPS) and total (MST), number of rows per ear (NFE), number of kernels per row (NGF), Average grain yield and grain hundred, weight (g) and dry matter of C. spectabilis (MSC). CLE consortium was characterized by the presence of predators and parasitoids, and M is mainly characterized by the presence of, phytophagous chewing f. suckers and also by predators. There was no difference between treatments for the damage caused by S. frugiperda on corn and by H. zea. He graduated two similar groups from the community of insects, f guilds. Chewing / f and parasitoids. sucking/predator. We evaluated the agronomic characteristics, corn production components and also the mass of dry matter production and C. spectabilis consortium. The different arrangements of C. spectabilis not affect the productivity of corn grains which averaged 5 t ha-1. However, LC arrangements of plants and reduced output CLE of dry matter of corn stem. The total dry matter in the consortium was on average 3 t ha-1.

    The present research focuses on the schooling of people with disabilities, especially the school evaluation of students with intellectual disabilities. The evaluation of school learning aims to diagnose the elements that are contributing and / or hindering learning and help in its improvement. The evaluation actions within the classroom reflect not only in the way of conceiving and applying the evaluation, but also in the schooling of students with and without disabilities. In this direction we must ask ourselves: How are teachers of the regular classroom, Elementary School, performing evaluations of school learning for their students with intellectual disabilities? What does Brazilian academic production reveal to us? The present research had as general objective to make a balance and analysis of the Brazilian academic production on the evaluation of the school learning of students with intellectual deficiency, enrolled in common classroom of the Elementary School. It is a systematic review of literature supported by the methodology of integrative bibliographical research. The results indicate that the number of academic researches that have the evaluation of the learning of students with intellectual disabilities in the regular classroom of Elementary School as an object of research and analysis is small; showed the concomitant occurrence of different conceptions about the intellectual deficiency and evaluation of the learning of these students; that teachers indicate that forms of evaluation are more than documents for the purpose of recording students' performance in the learning of school contents and recognize that the evaluation tools used have an important role. These were the data selected and analyzed by this research and may indicate a transition phase in the way of conceiving intellectual disability in the classroom and how to assess the learning of these students.

    The objective of this work was the development of a didactic sequence for the presentation of the set of complex numbers for the students of the third year of High School. The activities carried out prioritized the geometric approach, aiming at the application of operations in geometric transformations of figures (rotation, translation and homotetia), which represents one of the learning situations in the Student Book. These activities were carried out with the intention of minimizing the resistance and disinterest presented, in most cases, by students in relation to the content "Complex Numbers". Preliminary studies were carried out on the history and theory behind the didactic sequence.

    Metal complexes containing ligands that present biological activity have been attracting interest in the field of development of new drugs for the treatment of cancer. Lapachol and lawsone are examples of important natural products that exhibit antitumor properties. Thus, in the present work, new ruthenium(II) complexes containing lapachol or lawsone, phosphinic and bipyridine ligands, were synthesized and characterized, in order to obtain potential antitumor agents. Complexes were obtained with the following structural formulas: [Ru(L)(P-P)(bipy)]PF6 and [Ru(L)(P-P)2]PF6, where L = lapachol or lawsone, P-P = dppf = 1,1’-bis(diphenylphosphine)ferrocene, dppe = 1,2’-bis(diphenylphine)ethane, dppm = bis(diphenylphosphine)methane and bipy = 2,2’-bipyridine. The complexes were characterized by the techniques: elemental analysis, conductimetry, absorption spectroscopy in the infrared and in the visible ultraviolet region, cyclic and differential pulse voltammetry, 31P{1H}, 1H and 13C nuclear magnetic resonance, and X-ray diffraction of monocrystal (for the cases in which it was possible to obtain crystals). DNA interaction studies using spectroscopic titration, circular dichroism, agarose gel electrophoresis and fluorescence techniques showed that the complexes interact with the DNA by minor grooves. Analysis of the ability to interact with BSA by fluorescence measurements, allowed to conclude that the complexes exhibit a moderate interaction with the protein, with binding constants in the order of 104 - 105 M. In addition, the interactions occurred spontaneously, as evidenced by the negative values of ΔG°, involving hydrophobic and electrostatic forces. The cytotoxic activity of the complexes was investigated using the tumor cell lines of breast (MDA-MB-231 and MCF-7), lung (A549), prostate (DU-145) and non-tumor breast (MCF-10A) and fibroblast of gingiva (FGH). All complexes were active against the evaluated cell lines, presenting IC50 values lower than those obtained for the precursor complexes, free ligands and cisplatin. The complexes [Ru(lap)(dppe)(bipy)]PF6 and [Ru(lap)(dppm)2]PF6 showed to be more selective against breast tumor cells, MDA-MB-231, when compared to results obtained for non-tumor cells, MCF-10A. Therefore, these complexes were selected for the investigation of the possible mechanism of action against the MDA-MB-231 cells. Studies showed that these complexes caused greater changes in the morphology of MDA-MB-231 than in MCF-10A cells. In addition, the complexes showed to be able to act in the colonies formation process, reducing the number and size of the colonies. Cell migration assays have shown that the complexes act inhibiting the cell migration process. Another interesting property observed for the complexes was that they inhibit the formation of tubes in HUVEC cells, with or without FGF-2 growth factor, demonstrating that the complexes are antiangiogenic. Cell cycle analysis of MDA-MB-231 cells showed accumulation of cells in Sub-G1 phase, with a decrease in S phase. Cell accumulation assays showed that the complexes exhibit a greater accumulation in MDA-MB-231 than in non-tumor cells, MCF-10A. The complexes induced cell death by apoptosis, caused depolarization of the membrane potential of mitochondria, and induced ROS formation. In addition, was observed the activation of protective cell signaling through Hsp27, Bad, caspase 3, SAPK/JNK and Smad pathways. Given these results, the oxidative stress is a possible mechanism of cell death for the proposed complexes. The obtained results indicate that ruthenium complexes containing lapachol or lawsone present promising properties for the development of new chemotherapeutics for the treatment of cancer.

    The Specialized Educational Assistance is a right established in the Federal Constitution to all students with disabilities, being offered in the Multifunctional Resource Rooms that provide access to services and pedagogical resources and accessibility in schools of the regular network of education. To do so, it is necessary for the schools to provide adequate space for their installation, as well as a specialized teacher for ESA. The present study had as general objective to characterize the teaching performance in multifunctional resource rooms (SRM) of schools of the municipal teaching network of Macapá. Specific objectives were: a) to identify the public that receives specialized educational services in SRMs; b) know the operating conditions and referrals of students to SRMs; c) identify how the teacher organizes his / her teaching work, and d) verify what the teachers think about the school inclusion and implications in the teaching performance. It consisted of a research of qualitative character with exploratory-descriptive character and was realized in Schools of the municipal public network of education in Macapá; having as participants, six (6) teachers who worked in the Specialized Educational Assistance. The schools where the teachers interviewed worked were located in different areas of the city of Macapá, distributed between the North, South, East and West zones, totaling two (2) schools in the South zone, two (2) in the North zone, one ) in the West zone and one (1) in the East zone. The data collection was done through the application of an interview to the teachers who were selected through a lottery. The analyzed data were organized in thematic axes based on the information obtained in the interviews. The results revealed that ESA teachers have a positive conception about inclusion. It was found that a part of multifunctional resource rooms does not have all the necessary resources to attend students, and when they have resources such as games, equipment and computers, they do not work. Students are referred to the specialized educational service by the school secretary and in some situations, the Municipal Education Department, through the Special Education Division, conducts this referral. Participants indicated that the planning of student attendance is done, mostly in partnership with teachers in the regular classroom. As a result, it was also observed that teachers attend a very diversified clientele, which requires adequate training that addresses the demands demanded by the process of school inclusion and that foster student learning, which requires a proposal from the public sector training for these professionals. The data showed the importance of the support of families, the bodies responsible for special education and the school as a whole. It is hoped that this research can contribute with the scientific knowledge and that encourages future works that come to discuss about the Special Education in the municipality of Macapá

    Sugarcane vinasse is the main wastewater from the ethanol industry, produced in a proportion of about 12 liters per liter of ethanol. Among alternatives to its disposal, Fertirrigation is commonly used in order to improve soil fertility of crops near the sugarcane producing areas. However, it is currently being questioned due to its effects on the soil and on groundwaters, caused by nutrient lixiviation. An alternative would be the development of slow and/or controlled release systems based on biodegradable polymers, such as pectin and chitosan, using vinasse as the solvent. This could reduce the amount applied and allow the extension of fertirrigation covered area. This study proposed the development of pectin and chitosan particles by ionotropic gelation using vinasse as solvent, intending a possible application in agriculture. Besides the use of vinasse, the incorporation of Desmodesmus subspicatus defatted biomass was considered to enhance nutrient content. The particles were evaluated according to their visual aspects, average diameter, moisture content, pH, solubility in water and CaCl2 0.01 mol L-1, mechanical property, chemical composition, morphology and biodegradation in soil. In general, the particles showed homogeneous matrix and spherical shapes. Pectin/vinasse particles had an average diameter of 2.7 mm, moisture content of 16.0%, pH 3.0, soluble matter of 64 and 48 g 100 g-1 in water and CaCl2 0.01 mol L-1, respectively, and compression force of 31 N. Chitosan/vinasse particles had an average diameter of 1.9 mm, moisture content of 15.2%, pH 6.6, soluble matter 43 and 34 g 100 g-1 in water and 0.01 mol L-1 CaCl2, respectively, and compression force of 62 N. The addition of microalgae biomass did not greatly affect particles properties. However, it increased the concentration of N for pectin particles and the concentration of micronutrients for both particles. The developed materials were able to retain nutrients from vinasse and showed, as solid particles, 65-93% of mineralization after 36 days of contact with soil. According to the Brazilian current legislation, they can be classified as biofertilizers and represent a novel application in agriculture, allowing the recycling of nutrients from vinasse, biopolymers and microalgal biomass to the soil.

    In view of the difficulties encountered in the teaching of Combinatorial Analysis in public schools, both the student and the teacher of the High School, the present work has gained form to propose a differentiated approach. The work aims to approach Combinatorial Analysis without the use of formulas, because it has been perceived that Combinatorial Analysis is treated by many as a branch of Mathematics that needs to decorate formulas, mechanizing students' learning. With this, the content is titled as one of the most difficult in Mathematics, so we propose to work only with the Fundamental Principle of Counting (PFC) as a tool of the resolutions of the exercises. We worked on the proposal in practice with a high school room, and we get very good results. We hope that the study will be a material for studies of teachers and students.

    Head and neck squamous cell carcinoma (HNSCC) is a neoplasm that affects the regions of the oral cavity, pharynx and larynx with high incidence, reaching approximately 600 thousand new cases per year. Cases of local recurrence and distant metastases after treatment are common and decrease the rate of overall survival for patients with HNSCC, culminating in increased mortality rates, which have not improved for 40 years. The use of molecular markers, such as microRNAs, has been widely approached by the scientific community as a promising new methodology for tumor detection. This work aimed to the development of a genossensor with microlevels (cantilevers) of Atomic Force Microscopy (AFM) for analysis and detection of miRNA markers (miR-203 and miR-205) for the study of cervical lymph node metastasis. The genossensor was developed from the functionalisation process, which consists of the chemical modification of the surfaces of the microalvans, so that the complementary tapes of the miRNAs markers are immobilized and subsequently detect their target. Results obtained indicate that the proposed functionalization methodology was efficient, and confirmed the immobilization of the complementary tapes of the miRNAs markers, from the characterization by Fluorescence Microscopy and AFM morphological images. Detection of both miR-203 and miR-205 markers varied according to the different concentrations studied (100, 120, 140 and 160 nM). Through the developed genossensor it was possible to detect the target molecules: for the miR-203 marker, 10 to 72 nm cantilever deflection data were obtained, as well as for the miR-205 marker the deflection data from 10 to 170 nm. The innovative character of this work is contained in the development of a new methodology for the detection of metastasis, which, a priori, uses synthetic samples of HNSCC metastasis markers, but in the future it may be applied to real samples of patients affected by such pathology.

    In the past few years, many undergraduate and graduate students from a federal university in the interior of São Paulo state said they used different procedures to study English outside the classroom. In 2015, we proposed students of the 1st year of the Letters Portuguese/English course to write how they had learned English. All the answers showed that they had studied through television series, music, movies, games and the internet. Regarding this, students’ learning strategies (PAIVA, 2005), competences (ALMEIDA FILHO, 2016) and beliefs (BARCELOS, 2004) were investigated. However, we believe that these elements are related to the Spontaneous Competence (ALMEIDA FILHO, 2014). Considering this, we intend to comprehend the characteristics of the productive Spontaneous Competence. This qualitative and exploratory research (SILVEIRA e CÓRDOVA, 2009; SELIGER e SHOHAMY, 1989) was developed with Library and Information Science undergraduate students from a federal university in the state of São Paulo. They answered a questionnaire; they wrote a narrative; they had been observed in their English for Specific Purposes class; and their activities were analyzed. The data showed that different levels/types of motivation, affectivity, informal knowledge, learning strategies, attitudes, actions and other elements contributed to characterize this kind of competence.

    Studies focusing on the perspective of attitudes related to aging have pointed out how these can influence social structures and the treatment given to the elderly. This study answered the following objective: To identify and evaluate possible relationships between attitudes of teachers and elementary students - cycle 1, and the students' family members about old age. It is a correlational and comparative research, with quantitative approach. Data collection occurred in six public elementary schools (cycle 1) of a city in the state of São Paulo and was attended by 855 participants, who were divided into three groups: 53 teachers; 403 students aged between seven and eleven and; 399 families of the participating students. The teachers responded to the Neri Scale of Attitudes in relation to old age; the Palmore-Neri-Cachioni Questionnaire on Elderly Knowledge and a structured questionnaire addressed to Education professionals; the children responded to the Todaro Scale of Attitudes Regarding Old Age and a structured questionnaire directed at children; the family members answered the Neri Scale of Attitudes in relation to old age and a structured questionnaire addressed to the family members. Data were statistically analyzed using ANOVA test and two equal proportions, for comparison analyzes and Pearson's correlation test for the correlation analyzes. The participants' discursive responses were analyzed using the Collective Subject Discourse technique. The results did not show significant differences between the attitudes of the three groups, and in all groups there was a predominance of positive attitudes regarding old age. However, it has been shown that the attitudes of parents and children are correlated with each other. As for the teachers' group, the knowledge about aging was understood in this study as a low knowledge about the subject, and did not correlate with attitudes regarding old age. In addition, it was found that in all groups, those who mentioned having good or very good relationships with the elderly obtained more positive scores on the attitudes scales and also, it was observed that teachers and family members presented maintenance regarding the quality of the relationship established with children and adolescents up to the present time. Regarding the old age / aging approach in school, it was verified that although recognized as important, at the same time the theme is poorly focused or not focused, according to the teachers themselves and confirmed by the students' opinions. In addition, a positive correlation was observed between the teachers' attitudes regarding old age and the focus of the theme in the school. It discusses the importance of the quality of intergenerational relationships for positive attitudes towards old age and also about the importance of educational actions to combat age prejudice and attitudes towards old age. It is also pointed out the need to implement educational gerontology in Brazilian public schools and other environments and contexts with the possibility of expanding intergenerational contact and improving the attitudes and knowledge of people regarding old age.

    Traditional knowledge, scientific knowledge and the relationship between gender and science are studied in the area of Science, Technology and Society (STS). In this thesis, these themes were united and the traditional knowledge was investigated through the scientific knowledge produced in PhD and master theses, analyzing both the scientific community and the traditional community that were investigated in the studies. This thesis is part of a research agenda initiated in the master's degree and has as contribution to update the information and the advancement of methodological and theoretical instruments on the subject. The objective is to analyze the scientific production of PhD and master theses on the traditional and scientific knowledge. Through a quantitative and qualitative approach and using bibliometric analysis with content analysis, two hundred and sixty (260) theses available in the Digital Library of Theses and Dissertations of the IBICT, defended between the years 2010 and 2015, are analyzed. Information about date of defense, affiliation, authorship, supervision and co-supervision, funding, citation and content are examined. The results show that the number of theses defended by women has increased; most of the defenses were from the University of Brasília, mainly of the Sustainable Development Program; the largest number of defenses was from the subject area of Environmental Sciences; there has been an increase in the number of research theses conducted without funding; field study the approach mostly used; the most frequently investigated group was indigenous people; finally, Environmental / Socio-environmental / Ecological was the most highlighted thematic category in the theses, mainly looking at the relation of the traditional communities with the environment in which they live, demonstrating the insertion of the social aspects of science into scientific productions. In addition, as an important output of this research, a novel methodology that can be used in other bibliometric studies has been developed. The results may help future studies that address traditional knowledge, considering that the books, periodicals and authors that are part of the body of research have been identified.

    Este artigo estabelece uma rede de convergências discursivas entre a obra O Alienistade Machado de Assis e outros objetos culturais de diversos formatos e suportes por meio da análise hermenêutico-dialética, objetivando demonstrar uma ênfase constante na representação da ciência, por meio da figura do cientista e dos seus elementos circundantes. O trabalho compara estratégias diversas identificadas nessas obras, embasando-se em teóricos preocupados com o papel da ciência e sua imagem. Observou-se, em relação à obra principal, recorrência de uma imagem negativa, impressa por um comportamento excêntrico, antissocial, e autodestrutivo do cientista.

    With main focus to the educational rights established in the Constitution of the Federative Republic of Brazil of 1988 (CRFB / 88), the Statute of the Child and Adolescent (ECA), the Law of Directives and Bases of National Education (LDB / 1996) and the Racial Equality Statute. This is a qualitative research, involving field research with application of questionnaires and documentary analysis. Fifty professionals participated voluntarily in the research, among them teachers, pedagogical coordinators and principals. After the data collection, the data were tabulated in a spreadsheet and categorized. The analysis indicates that there are gaps in the study of legislation, both in the initial and ongoing training of participants. Teachers state they have difficulty understanding and understanding these laws, and most say they do not have the skills or do not know what to do in case of suspected or confirmed maltreatment involving their students. The research also shows the lack of approach to the topic in the HTPCs and the lack of provision of continuing education courses in educational legislation maintained by the Public Power. Thus, we conclude that teachers of the reality investigated need a greater mobilization for the subject and that initiatives are carried out so that it is linked in its daily life. This incentive should be stimulated in the initial training courses and also be fostered in professional teaching experience, based on articulations between the management team and other organs of the Public Power , despite the existence of several laws aimed at guaranteeing the rights of children and adolescents, it is necessary to seek the effectiveness of legal norms in order to be able to defend and guarantee the rights of learners.

    Sweet sorghum has been considered an agricultural crop with great potential for the production of bioenergy, recommended for cultivation in sugarcane reform areas to supply raw material for the production of ethanol in the off-season of sugarcane in Brazil. Depending on the bioethanol production system, the entire sweet sorghum plant is harvested, with large exports of nutrients from the agricultural area. Although there is little information in the literature on more specific fertilizer management for sweet sorghum, nitrogen fertilization with 20-40 kg ha-1 of N at sowing and 60-120 kg ha-1 of N in topdressing fertilization is currently recommended. The volatilization of N from urea, the nitrogen fertilizer most used in Brazilian agriculture, is one of the main routes of N loss and one of the main reasons for the low efficiency of nitrogen fertilizers. One of the recommended practices for reducing N losses through volatilization is the incorporation of urea into the soil. Due to the practical difficulty and costs of this operation, some innovative technologies have the possibility of producing stabilized fertilizers, including urea with the additive N- (n-butyl) thiophosphoric triamide (NBPT), a urease-inhibiting substance that slows down the rate of urea hydrolysis and reduces N losses through volatilization. The objective of the work was to evaluate the agronomic performance of sweet sorghum fertilized with common urea and with urea with urease inhibitor NBPT for the supply of the recommended N in full dose at sowing or in split doses at sowing and topdressing fertilizations. The experimental design consisted of four randomized blocks, consisting of six treatments: T1 - control (without fertilization); T2 - control (without nitrogen fertilization); T3 - common urea applied at planting; T4 - common urea applied in split application (planting and topdressing); T5 - urea with urease-NBPT inhibitor applied at planting; T6 - urea with urease-NBPT inhibitor applied in split application (planting and topdressing). The plant height, stalk production, dry and fresh matter, panicle mass, stem diameter, number of stems, number of tillers, and the leaf contents of N, P, K, Ca, Mg and S were evaluated. The treatments did not produce significant differences in the biometric and yield parameters and in the leaf contents of macronutrients. The AGRI-001E hybrid of sweet sorghum showed an average of 4.7 m in height and stem diameter of 1.5 cm, with fresh and dry matter yields of 109.2 and 35.1 t ha-1 , respectively. The stalk production was 85.7 t ha-1 and was well above the minimum accepted by the sugarcane industries (50 t ha-1). The leaf contents of N, P, Ca and Mg were considered adequate. There was nutritional deficiency of K and S detected by chemical analysis of plant tissue, with no visible symptoms.

    This study originated from the perception that some productions that are linked to Paulo Freire's pedagogical perspective do not appear to be related to their theoretical foundations and their political-pedagogical objectives. From this perception came the problem of this research, which confronts Freirean epistemology with the official Sorocaba curriculum, since the supporting documents claim to be based on Freir-ean foundations, whose episteme is significantly exposed in the works "Pedagogy of the oppressed" (1987) and "Extension or Communication?" (1983), of this author. With this finding, we ask ourselves which are the main epistemological references that support that curriculum, and what implications they cause in the systematization of those documents. For this reason, the general bibliographic review was followed, beginning with the visit to the above quoted author's works, cutting important pas-sages to determine the freirean categories that served as tools for the analysis of the document, and which were compared with excerpts from the works of thinkers of phenomenology and Marxism, mainly with whom Freire demonstrated proximity, in order to detect influences arising from it. The following is a list of the documents that underpin the Sorocaba curriculum: the 2016 Reference Framework, which reflects the theoretical basis of the 2012 Curricular Matrix, which is based on contents and practices that determine the subjects of the serial, to detect if these, claiming to fol-low the work of Freire, are committed to its foundations and political objectives. It should be noted that Freire appropriates primary concepts of existential phenome-nology, from which education derives as a political act, in addition to demonstrating convergence with Marx's thoughts, culminating in the categories of dialogue and political commitment as a humanizing practice; these the knowledge that served as tools of analysis for the documentary stage of the work. As a result, it was found that the Referential Framework brings perspectives and quotes from progressive authors close to the Freirean proposal and even cites them directly, but the content and prac-tical issues of the Curriculum Matrix are based on different political-pedagogical ob-jectives.

    Prochilodus nigricans is a migratory detritivorous fish, with a silvery grey colored body and dark, irregular, wavy, bar-like patterns on the caudal-fin lobes. This species is widely distributed in the Amazon and Tocantins river basins and stands out for its great economic importance and social relevance due to subsistence fisheries. Because of the uncertainties recently raised regarding the validity of the species, the aims of this work were to access the genetic diversity of P. nigricans in the region of the Brazilian shield and to characterize the genetic-population parameters of this species in the sub-basin of the Tapajós river during a nonreproductive period. In order to test the occurrence of hidden diversity, we used the mitochondrial markers COI and ATP6/8 in samples from the Tapajós, Xingu and TocantinsAraguaia sub-basins, and conducted a GMYC analysis with COI, considering the sequences generated in the present study and Genbank sequences of individuals sampled in other regions of the Amazon basin. Population structure and genetic diversity analyzes were performed using eight microsatellite loci and, the ATP6/8 genes and the mitochondrial DNA control region. For both COI and ATP6/8, there was a significant divergence between individuals sampled in the Tapajós river, with genetic distance values ranging from 1% to 1.9% between this group and the other individuals sampled in the Brazilian shield. The GMYC analysis identified that these individuals constitute another MOTU (molecular operational taxonomic unit), which were excluded from the population analyzes conducted in the Tapajós sub-basin. Mitochondrial and microsatellite data evidenced three genetically differentiated populations, Tapajós, Teles Pires and Juruena, the latter of which was genetically more differentiated. The three evaluated populations presented high and similar genetic diversity values to those of other species of Prochilodus and showed no signs of population expansion or decline in the last 200 thousand years. The results obtained in the present study on the diversity of P. nigricans are of particular relevance, since they make possible a previous diagnosis of the genetic status of P. nigricans populations in the tributaries and the main channel of the Tapajós river, before the eventual effects caused by the implantation of dams. Such data will serve as a basis for future studies to evaluate the impact of these constructions on the distribution pattern of the genetic diversity of migratory species, serving as an important tool to observe changes in the genetic structure of populations in areas fragmented by dams, and to subsidize management programs that aim at the conservation of the ichthyofauna in these regions.

    The relevance of the beef chain to the Brazilian economy has increased in the last two decades. This growth has been accompanied by the advance of cattle production and agro-industries to areas located within the Legal Amazon. The impacts of this displacement have been contested by stakeholders. These actors attribute to the beef supply chains originating in that region a set of negative social and environmental repercussions. On reaction of the slaughterhouses in response to this challenge is the implementation of risk management systems that mitigate possible damage to their reputations caused by the publicizing of the possible deleterious effects of their activities. In this context, this study aims to analyze how the slaughterhouses in the Amazon region identify socio-environmental factors of suppliers that have the potential to raise their reputational risks and also the strategies used to mitigate these risks. For that, a qualitative exploratory study was developed through a multiple case study. The results showed that risk factors are largely established in public commitments negotiated with stakeholders. Deforestation, invasion of indigenous lands, work analogous to slavery and destruction of protected areas are the most cited factors as reputational risk generators. As risk mitigation strategies, the slaughterhouses maintain socio-environmental assessment practices of all their suppliers through a system of registry verification of the existence of infractions in the farms. Verification system auditing and reporting to the stakeholder are also used. The mitigation strategy of avoiding the risk changing supplier is more frequent. Other forms of mitigation are also observed, but it is noted that the risk is accepted when the stakeholders' perception indicates that the slaughterhouses are not responsible for livestock irregularities.

    In Brazil, workers´ health policies were significantly developed based on the Federal Constitution, which consolidated health and work as citizenship rights. Workers´ health was included in the Unified Health System and structured by the National Network of Integral Attention to Workers' Health, connected to the Health Care Network through the Workers´ Health Reference Centers, which play a fundamental role in articulating actions. Workers' health is a broad and complex field and includes investigation and intervention, articulating interinstitutional and interdisciplinary knowledge and practices with a view to promoting health and preventing work-related risks and injuries. Occupational Health Surveillance is a priority strategy to ensure protection, prevention and promotion of workers´ health, through the integrality of actions, multiprofessional action and complementarity of various services. Considering that work plays a fundamental role in the formation of society and of humans as social beings, this study is based on the assumption that changes in labor relations affect workers' health and, consequently, their labor, families and social relations. Occupational Health Surveillance is implemented in Brazilian states and municipalities in a decentralized way according to the principles of the Unified Health System. Moreover, it is the municipalities´ decision, based on their realities, to establish criteria, goals and implementation systems. This study is based on the historical-dialectical materialism framework, which considers human consciousness as a social product, which is changeable and historical, and economic and social transformations, determined by the evolution of the means of production, as well as all the natural or historical things that are not static and finished facts, but are always in motion. It is aligned with the workers´ health framework, which seeks the integrality of care and surveillance in care for workers. Thus, this study aims to analyze Occupational Health Surveillance actions in the municipal sphere. A qualitative study was carried out in two stages: the first stage consisted of a documentary survey of the legislation related to workers' health at the municipal level, as well as other documents that consider the implementation process, information flows and processes concerning occupational health care in the Unified Health System. The second stage included interviews with 15 key professionals (managers and decision makers) linked to the various sectors of the municipal, regional and state health system and other organizations that interface with workers´ health. It was carried out in a medium-sized municipality in São Paulo state, linked to a Regional Workers´ Health Reference Center in conjunction with the Sanitary Surveillance Group and Regional Health Board, following the municipalization process of workers´ health actions in 24 municipalities. The documentary survey related to implementing the Occupational Health Surveillance actions in the municipal sphere showed evidence of a lack of information on the subject. Three legislations focusing on worker´s health resulted from this stage: Deliberation of the Intersectoral Committee on Male and Female Workers´ Health and two Health Plans. Keynote speeches highlighted various weaknesses when developing actions in Occupational Health Surveillance, pointing out that, despite advances in the municipalities in the area of workers´ health, actions are still fragmented and disjointed, there is a lack of knowledge about the roles and competencies of the sectors and actors involved, and there is a critical need for structuring that surpasses curative and palliative actions concerning the prevention of accidents and diseases related to work and health promotion. The findings also indicate that Occupational Health Surveillance is the result of a network in motion, which should be articulated with the principles of the Health Care Network and the Unified Health System. This study analyzed Occupational Health Surveillance in the municipal sphere from the perspective of the actors that are part of it, contributing with local contexts and also with other municipalities that experience similar situations, focusing on the transformation of reality and improvement of workers´ health.

    A biological monitoring program using a Index of Biotic Integrity (IBI) in the Alto Sorocaba Basin will be efficient for quick evaluations, cost-effective, and analysis efficiency, and may assist in public power decision-making in directing of efforts to conserve the aquatic biota and to identify and minimize the physical habitat losses of the streams in the region. This work aimed to adapt a integrity biotic index (IBI) for the streams of the Alto Rio Sorocaba sub-basin. In the region of study is located the main source of the Metropolitan Region of Sorocaba (RMS), the reservoir of Itupararanga. Measurements of environmental characteristics and fish collections were carried out in 8 streams. Fish communities were analyzed using 27 biotic variables related to composition, diversity, trophic structure and habitat use. The biotic variables were selected concerning range, responsiveness and redundancy. A physical habitat index (IFH) was used to evaluate environmental characteristics. The IFH was elaborated from the variables: substrate stability, speed and depth variability, flow stability, sample pool, runs and riffles, vegetation cover and bank stability. The IBI was validated using PHI correlation significance. From 27 biotic variables tested, four were selected: siluriform richness proportion, siluriform individuals proportion number, omnivorous individuals proportion number and trophic categories number. These measures represent the abundance, species diversity and trophic structure, not expressing species composition and habitat use, which is a limiting factor to the use of the index to obtain more comprehensive results about the environments. No stream was rated as excellent and none as without fish. Fifty percent of the streams were classified as regular and 37.5% in the good category, demonstrating that many streams can still be used as reference. Despite its limitations, the adapted IBI is a useful tool for future biological monitoring and long-term biodiversity conservation and at low cost.

    Privacy is the cause of an important concern in the context of mobile applications, once these applications manipulate a countless number of the users’ confidential and personal information through their mobile devices. Previous researches have shown that the manipulation of information through the applications is commonly unknown to the user, or, when known, the reason for this collection is not clear enough. Several automated tools have been proposed to analyze the performance of mobile applications regarding their privacy. However, these tools don’t take into consideration the users’ perception about what they believe to be collected and the purpose of this collection. Concerning this, the current work presents an approach for privacy applied in the mobile context, in which people’s expectation of the aspects of collection and the use of information by smartphone applications are considered. This study shows the results of a research performed with 163 smartphone users which was used as a basic resource to understand how people’s expectations may impact their subjective feelings (levels of comfort). WePrivacy service is also presented, mainly composed of a mobile application, a concept which implements the idea of privacy and responds the question of research discussed in this work, that is, how to consider people’s expectation in the evaluation and support to the decision making on privacy in the use of mobile applications. The results found suggest that the users don’t know how to point which of their personal information are collected and to which purpose the collection serves. The results also show that when the purposes of the collection are known, the users tend to feel more comfortable.
