This research focuses on looking at the life trajectory of young people in conflict with the law living in the county of São Paulo-SP, which introduces new forms of performance of socially marginalized youths, questioning stereotypes that associate youth action violence, transgression, drugs, trafficking, political indifference, resignation for alleged public space and school. The focus is to dialogue with the stories of life young in conflict with the law in seeking to understand what meaning they attach to the offender act, for it were asked 15 young collaborators for interviews within the Program Socio-Educational measures in Half Open. The life stories narrated by young in conflict with the law were initially transcribed verbatim, and subsequently textualized finally transcriadas. The theoretical and methodological rationale was based on studies by José Carlos Sebe Bom Meihy, coordinator of the Center for Studies in Oral History of USP (NEHO). The research used pivotably Oral History of Life and thematic oral history, highlighting the stories of fragments young with the aim of understanding the social context to which they belong, playing educational processes seized, the place for the school and informal work. The transcreation allows inaugurate a process of creation and dialogue with lives (re)created in narratives. Thus, the main theorists were prioritized Michel Maffesoli, Áurea Maria Guimarães, Marisa Feffermann, José Carlos Sebe Bom Meihy, Alberto Lins Caldas. Such authors show the uniqueness of the stories of lives that are intertwined with other stories within practices, historically and culturally developed, providing new forms of relationship. The street learning stands out as a possible way for these young people as a result of numerous failures of public policies.

The replacement of natural cover, by other land-uses, associate with the forest fragmentation process can result in the decrease of forest connectivity in the landscapes. The diagnosis of landscape structure, through the landscape ecology metrics, intende to direct the restoration activities and the evaluation of forest connectivity. The study aimed at the evaluation of forest connectivity in the the National Forest (FLONA) Capão Bonito and its surrounding area, in the state of São Paulo, Brazil. We produced a land-use/land-cover map, through supervised digital classification, and calculated the landscape metrics (patch and class level) for study area. Selected metrics (Area, ENN and Shape) were used in the production of sustainability index (SI). The forest patches were classified in levels of priority for forest restauration, through SI. In order to identify the forest connectivity was calculated the Integral Index Connectivity (IIC) and we realized the redundancy analysis (RDA), the non-metric multidimensional scaling (NMDS) and multiple regression. Detection was performed by the bird fixed points method and the composition of bird community was obtained through the abundance of species. The diversity index of Shannon Weaver (H ') and species richness was calculated. The land-use/land-cover map indicated that the landscape´s matrix is agriculture, with native forests occupying only 24.45%. The main focuses of forest restoration are the fragments associated with the highest values of SI, because they can guarantee the maintenance and/or the restoration of biodiversity. It was obtained that the IIC =1.000 m influenced in the variance of the birds community and, the shape metric was the main factor that influenced in the composition, richness and diversity of birds. We concluded that is possible to evaluate the connectivity axes using avufauna. The RDA permits the identification of maximum spread for birds. The shape of forest fragments is one of the main factors, influencing in bird community because it is relate with edge effect and forest landscape connectivity. The SI is a simple and effective method for express the priority patches for forest restoration.

Habitat loss and fragmentation are currently the main causes of the global extinctions, caused mostly by replacing of the native vegetation by different land-uses. The graph theory supports the understanding of the landscapes, considering the permeability of land-uses/land-covers. The objective of this study was to evaluate the influence of the landscape spatial patterns, in this case National Forest (FLONA) of Capão Bonito and buffer zone, in the bird diversity. We defined 80 collection points in the four levels of forest connectivity, previously defined in the landscape, which were visited five times. The “fix point” method was used for species detection, with 10 minutes for sampled time. We calculated Shannon Wiener diversity index (H '), Abundance Index values (IPA), richness in order to evaluate changes in the bird community, besides the classification of species by trophic categories. The land-uses/landcover were grouped into MNA (Forest); FP (pine, araucaria and eucalyptus) and AGRP (agriculture and pasture). We evaluated the similarity among this groups, considering the IPA and species numbers, through non-metric multidimensional scaling graphics (NMDS). According the analysis there was similarity between MNA and FP, which are heterogeneous, increasing the stability for birds at the landscape scale. Although, the dissimilarity obtained for AGRIP is consequence of the land-use be a homogeneous environment, with less diversity of resources. The evaluation of the matrix permeability was analyzed from the perspective of graph theory, using the Connectivity Integral Index (IIC), redundancy analysis (RDA) of NMDS and multiple regression. The IIC was generated for two situations: with the impedance values (IICc) and without (ICCe). We defined the follow resistance values: 30% for agriculture and 60% for pasture. The permeability analysis indicated agriculture as land-use with the most influence in the bird community variance. So, we concluded that the less complex sites has the less diversity and species richness than the sites more complexes.

It is well know that the respiratory network, undergoes significant development in the postnatal period. Among various processes, the maturing of the catecholaminergic (CA) system shows to be an important factor in the control and modulation of respiratory rhythmogenesis. Studies have also shown that these neurons are widely distributed in the Central Nervous System (CNS), including the A1/C1, A2/C2, C3, A5, A6 and A7 regions, having numerous projections to many regions of the brain. However, the development of respiratory network as well as its effect on the control of ventilation, is not yet fully understood. Thus, understanding the participation of CA neurons in the respiratory control during postnatal development is of most importance for a better understanding of some clinical disorders including Rett Syndrome, Sudden Infant Death Syndrome (SIDS) and Central Congenital Hypoventilation Syndrome (CCHS). Therefore, this study aimed to investigate the involvement of CA neurons in the brainstem on respiratory control in normoxic normocapnic, hypercapnic and hypoxic conditions during the postnatal period of male and female neonatal rats, through chemical injury with conjugated saporin anti-dopamine beta-hydroxylase (DBH-SAP). Thus, DBH-SAP (42 ng/100 nL – 1L), saporin (SAP – 1L) or phosphate buffered solution vehicle (PBS, 0.01M, pH 7.4 – 1L) were injected into the 4th ventricle in male and female neonates Wistar rats P0-1. Pulmonary ventilation ( EV ) was recorded in unanesthetized neonates (P7-8) by pressure plethysmography during normocapnia, hypercapnia (7% CO2) and hypoxia (10% O2) at 10 and 20 min after the start of exposure. Our data demonstrate that lesion of brainstem CA neurons increased ventilation in males and females newborn under room air conditions. In addition, the ventilatory response to hypercapnia was significantly reduced in male (57%) and female (55%) lesioned neonatal rats (Male – SAP group: 212.8 ± 7.0; PBS group: 203.9 ± 10.3; lesioned group: 151.1 ± 7.4; P < 0,001; Female – SAP group: 218.2 ± 10.4; PBS group: 200.0 ± 6.4; lesioned group: 154.0 ± 9.6; P < 0,001; all values relative to % of baseline). Also, a similar reduction was observed in the hypoxic condition (Male – SAP group: 185.2 ± 15.3; PBS group: 167.4 ± 5.0; lesioned group: 110.8 ± 9.2; P < 0,001; Female – SAP group: 197.3 ± 11.8; PBS group: 179.5 ± 13.7; lesioned: 129.4 ± 5.9; P < 0,001; all values relative to % of baseline). Additionally, the values for metabolic rate of control and lesioned groups, both males and females, did not differ significantly, whether in normoxic normocapnic, hypercapnic or hypoxic conditions. These results suggest that brainstem CA neurons exert a tonic inhibitory role in neonatal ventilation and promote an important excitatory modulation in CO2 and O2 chemosensitivity in unanesthetized males and females neonatal rats (P7-8).

Third places, a term coined by sociologist Ray Oldenburg to describe places other than home (first place) or workplace (second place), places where people attend to socialize with others besides co-workers and family. Third places provide neutral ground for people to express themselves freely, necessary for civil society and civic engagement, helping to create in their regulars the feeling of belonging. Parks, cafes, bakeries, museums, theaters, churches, bars and squares are examples of third places. These places have a key role in community life forging their cultural profile. Such places are characterized by being democratic and accessible, allowing people to discuss politics, the last football game, or the next music festivals, strengthening the notion of community. However, the modern lifestyle and the potential lack of third places can lead people to be more solitary or even have fewer opportunities to attend places that promote socialization, affecting the quality of life and the sense of community. In this context, this research explores how Information and Communication Technologies (ICTs) can provide people opportunities for socializing in a third place, but unlike Oldenburg, independent of the location constraints and time, creating the phenomenon defined as thirdplaceness. Thus, it is expected to use ICTs to go beyond the traditional third places, providing opportunities for people to meet and socialize, reinforcing and extending the concept of third place, as well as confronting the stigma of isolation using technologies. To experience the support of ICTs to thirdplaceness even when there is no conventional third places to bring the community together, it is considered in this proposal the development and the use of an ICT interactive public art installation, called WishBoard. This installation explores the potential of interactions between mobile devices and public displays, allowing people to share with the community messages and their individual aspirations. This public sharing would be the opportunity for people to socialize in that space during the deployment. From the analysis of the shared messages, it was analyzed the role of ICTs to promote thirdplaceness and found evidence the cultural profile of the community in the shared anonymous messages. Considering the content of messages and the behavior of people, it was noticed that the use of public displays combined with interaction on mobile devices can promote a transformation of the place into a meeting place and conversation when they provide a way for individual self-expression and contemplation by the community that expression, causing engagement among people.

In this study nanocomposites of polyamide-6 (PA-6) reinforced with silica nanoparticles (SiO2) were prepared in order to promote improved mechanical properties for engineering applications. The nanoparticles’ surfaces were chemically modified with the silane agent 3-aminopropyltrimethoxysilane (3- APTMS) to improve the chemical and physical interactions between them and the PA-6 matrix. Nuclear magnetic resonance analysis (NMR) and Fourier transform infrared absorption spectroscopy (FT-IR) showed that 3-APTMS grafting on nanoparticles surface was accomplished. The nanocomposites mixing process was studied in two forms: by torque rheometry, using a torque rheometer internal mixer; and in a co-rotating and intermeshing twin-screw extruder. A preliminary study of the influence of processing variables at the torque rheometer on the degradation of polyamide-6 matrix was performed. The results showed that the greater the filling volume of the mixture in the chamber and the rotational speed of the rheometer’s rotors, the lower the degradation of the polyamide-6. Based on this preliminary study, compositions with 1, 2, and 4 % weight of SiO2 nanoparticles, both unmodified and chemically modified with 3-APTMS were prepared in the torque rheometer. The nanocomposites were compression molded and it was observed that nanocomposites reinforced with 1 wt.% SiO2, both unmodified and surface-modified, presented the best tensile properties. For the nanocomposite samples processed in the twin-screw extruder, the influence of relevant variables – nanoparticle content, chemical surface modification, physical form of the fed PA-6 (granule and powder), rotational speed of screws and extruder feed rate – on mechanical, thermal, and dynamic-mechanical properties were studied. The samples were afterwards injection molded and it was observed that the samples produced using 1 wt.% surface-modified and 100% finely ground PA-6 showed the higher tensile modulus and yield strength values.

In the present study the aim is to investigate the role of sexuality in the development of sociability in Jean-Jacques Rousseau. This research works in two contexts. The first comprises the denaturation of man in general and the general formation of societies; in this case, the works that support this reading are: Discourse on the Origin of Inequality, Essay on the Origin of Languages, Social Contract and Fragment of the Climates Influence on the Civilization. The second context comprises the education of the man from nature prepared to live in any kind of society. In this case, the work that supports this reading is Emilio, or On education. In both, first or second context, the socialization process of specie and the development of sociability in the individual can be divided into distinct stages in which sexuality acts, alternately, in the nuances that separate these stages. By their specific character, the sexual need allows a way to understanding the relationship between the instinct and the genesis of passions. In this context, the sexuality operates as a kind of catalyst for social potentialities that places the society in the horizon of man as a possible way of collective survival or as a specific destination of specie. In short, the sexuality is a little studied topic in Rousseau; however, it is a possible interpretation key to understanding how the man, who was not social by nature, found the sociability as a proper element to their nature.

The titanium dioxide nanoparticles (NP-TiO2) has achieved into aquatic ecosystems through different sources, such as sewer and leaching. Abiotic factors such as pH, ionic strength, water hardness may change the chemical aggregation of NPs as well as the bioavailability of metals in waters result of speciation and /or complexation with other compounds. Considering the pH variations can occur in the environment naturally or as a result of ecological accidents and the increasing use of NP-TiO2 in many different industries, this study aimed to determine the CL-50; 48 hours of NPTiO2 in different pH (acidic, neutral and basic) in juvenile Prochilodus lineatus (curimbatá) and evaluating the effects of exposure to sublethal NP-TiO2 these pH using biochemical, physiological and morphological biomarkers. After sensitivity test with KCl, the animals were tested with different concentrations of NP-TiO2 at pH 5.0, 7.0 and 8.0 for 48 hours to determine the CL-50; 48h. Subsequently, the animals were exposed to 1 mg L-1 NP-TiO2 for 48 hours at different pH. After the exposure period, blood samples were obtained via caudal puncture for ion plasma analysis and hematologic variables, and samples of gills were collected and fixed. The analytical characterization of NP-TiO2 suggest the aggregation ability are modified of the NP at different pH and at pH 5.0, the hydrodynamic diameter of the NP is much larger then the others pH, which may have create difficults for the entry of NP in organisms and caused less damage. The NP-TiO2 were considered non-toxic in pH 5,0, 7,0 and 8,0. Exposure to NP-TiO2 pH 5.0 and ionic imbalance caused in the exposed animals, possibly due to changes in the concentration of Cl- ions. Exposure to pH 5.0 and 8.0 and NP-TiO2 at pH 7.0 inhibited AC enzyme. In animals exposed to NP at pH 5.0 were not identified cloride cells with crypt surface, possibly due the blocking of these surfaces by the large NP aggregates. Changes in concentrations of ROS and SOD, CAT and GCL activity may indicate an imbalance in antioxidant system due to different pH and NPTiO2 exposure. NP exposure caused major damage at pH 7.0, where have lower hydrodynamic diameter , supporting the hypothesis that the smaller the size of the cluster,it’s easier the NP enter the body of the exposed animals.

Reactive oxygen species (ROS) are products naturally generated by the cell metabolism and at low levels play an important physiological role in intracellular regulation, whereas in excess can cause damage to cells. To combat this damage, cells present a complex defense mechanism including different enzymes which act as antioxidants. Among these enzymes, and especially in cells such as erythrocytes, which are exposed to high levels of molecular oxygen, the Peroxiredoxins (Prxs), stand out for the abundance and great reactivity with its substrates. In this cell type, when occurs hemolytic diseases such as sickle cell anemia and beta thalassemia, increased production of ROS and consequently oxidative damage are observed, greatly aggravating the clinical picture of patients affected by these diseases. In these diseases, the PRDX2 appears to be a major line of antioxidant defense, as it is the third most present protein in the cytosol of the erythrocyte. Therefore, this study aimed to assess the role of PRDX2 in differentiated K562 cells for the expression of erythroid characteristics, through gene silencing using shRNA_PRDX2. It was possible to obtain a 70% of the PRDX2 expression inhibition, which caused a decrease in the proliferation, cell viability and interaction, showing the importance of PRDX2 in oxidative protection on this cell type. In order to evaluate the modulation of antioxidant system in these cells, we also analyzed the pattern of gene and protein expression of all other PRDXs beyond the gene expression of other antioxidant enzymes during the process of differentiation. We found that inhibition of PRDX2 expression adversely affects the expression of PRDX5 and causes increased expression of their biological reducing agents, which increase the recycling PRDX2, compensating for their lack the cell. These data are not get described in the literature and additional analysis is needed to better understand this interaction beyond the molecular mechanisms involved in the expression of related enzymes in protection against ROS. Understanding these mechanisms seems important to work with a better insight of the pathophysiology of hemolytic diseases by identifying possible targets to assist in the management and can mitigate the effects of the disease in these patients.

Cardiorespiratory responses to peripheral baroreceptor activation are affected by sodium balance or anesthesia. In the present study, we investigated the baroreflex sensitivity and cardiorespiratory responses: to baroreceptor activation and deactivation with intravenous (iv) infusions of phenylephrine (phenyl) and sodium nitroprusside (NP) with or without angiotensinergic type 1 receptor (AT1) blocking; to baroreceptor activation with iv infusions of angiotensin II (ANG II), and cardiorespiratory responses: to cardiopulmonary receptor activation with iv infusions of fenilbiguanide: to chemoreceptor activation with iv infusions of sodium nitroprusside (KCN) in normovolemic, sodium depleted, and sodium repleted unanesthetized rats. Male Holtzman rats (280-320 g, n = 8 - 19) with a polyethylene tubing inserted into abdominal aorta through femoral artery to record mean arterial pressure (MAP) and heart rate (HR) and femoral vein to perform iv administration drugs were used. Respiratory frequency (fR), tidal volume (VT) and ventilation (VE) were recorded by whole-body plethysmography. Sodium depletion did not modify baseline MAP (102 ± 2, vs. normovolemic: 107 ± 2 mmHg), HR (382 ± 9, vs. normovolemic: 385 ± 7 bpm) or VE (468 ± 27, vs. normovolemic: 447 ± 26 ml/min/kg). Iv infusion of phenyl (5 μg/kg/ml, 0.011ml/s) in normovolemic, sodium depleted and repleted rats produced similar pressor (Δ +58  2, +59  2 and +60  3 mmHg, respectively) and bradycardic (Δ -97  10, -120  11 and -110  9 bpm, respectively) responses, however, sodium depleted rats showed an increased in VE (Δ +152  40, vs. normovolemic: +53 ± 26 ml/min/kg, p<0.05). After sodium repletion the VE returned to approximate value of normovolemic rats (Δ +125  50 ml/min/kg). In the other group of animal was made AT1 receptor blocking with iv bolus injections of losartan and was observed an attenuation of VE that was increased in sodium depleted rats (Δ +77 ± 33 ml/min/kg). 9 The bradicardic component gain also was increased in depleted rats (-1.9 ± 0.1, vs. normovolemic: -1.3 ± 0.1 bpm/mmHg, p<0.05) and returned to baselines values in sodium repleted rats (-1.5 ± 0.1 bpm/mmHg). Iv Infusion of NP (30 μg/kg/ml, 0.011ml/s) in normovolemic, sodium depleted and repleted rats produced similar hypotensive, tachycardic responses, similar VE and the tachycardic component gain. The iv infusion of fenilbiguanide (50 μg/kg/ml) induced similar hypotensive and bradicardic responses in normovolemic and sodium depleted rats, however increased VE in sodium depleted rats (Δ +281 ± 34, vs. normovolemic: +150 ± 50 ml/min/kg, p <0.05). Iv infusion of potassium cyanide (KCN, 40 μg/0.1ml per rat) did not change cardiorespiratory responses. Thus, the results suggest that sodium depletion with furosemide plus sodium-deficient diet increased bradicardic component of baroreflex and the neurondocrine changes produced by sodium depletion (like increased angiotensin II) may facilitate respiratory responses to baroreceptor activation with phenyl iv.

The research project, of qualitative character presented and analyzed a scientific literacy activity process carried of 2 groups: the first group of undergraduate students and the second group of high school students. The scientific lieracy promotion is necessary considering the public indifference about science, once a lot of people have problems to understand and relate it to their daily lives. In this process, the scientific literate is capable to understand not only the science itself but also to perceive it their day by day, contributing in the future as conscius citizens. The comics were chosen as the main topic of the project due to singular attributes, using both the image and text to transmit an information or message, and constitute an interesting tool to promote the creative process of an individual or a group. The japanese comics, called manga, were chosen to support drawing activities and workshops with the students. Aiming for promoting the students scientific literacy and diffusing the practice of science communication by comics in manga style, were proposed several activities such as Chemistry workshop, technical visits to research departments, drawing and comics activities. At the end of the project, the students elaborated and presented comics about science communication, including chemistry. The research project promoted the scientific literacy of the students and also contributed to the dissemination of chemistry by production of scientific comics.

Latterly, the development of data mining techniques has emerged in many applications’ fields with aim at analyzing large volumes of data which may be simple and / or complex. The logistics of transport, the railway setor in particular, is a sector with such a characteristic in that the data available in are of varied natures (classic variables such as top speed or type of train, symbolic variables such as the set of routes traveled by train, degree of tack, etc.). As part of this dissertation, one addresses the problem of classification and prediction of heterogeneous data; it is proposed to study through two main approaches. First, an automatic classification approach was implemented based on classification tree technique, which also allows new data to be efficiently integrated into partitions initialized beforehand. The second contribution of this work concerns the analysis of sequence data. It has been proposed to combine the above classification method with Markov models for obtaining a time series (temporal sequences) partition in homogeneous and significant groups based on probabilities. The resulting model offers good interpretation of classes built and allows us to estimate the evolution of the sequences of a particular vehicle. Both approaches were then applied onto real data from the a Brazilian railway information system company in the spirit of supporting the strategic management of planning and coherent prediction. This work is to initially provide a thinner type of planning to solve the problems associated with the existing classification in homogeneous circulations groups. Second, it sought to define a typology of train paths (sucession traffic of the same train) in order to provide or predict the next movement of statistical characteristics of a train carrying the same route. The general methodology provides a supportive environment for decision-making to monitor and control the planning organization. Thereby, a formula with two variants was proposed to calculate the adhesion degree between the track effectively carried out or being carried out with the planned one.

With more advanced marketing relations, various changes are taking place in regard to competitive factor markets, among which, the importance of quality processes and goods supplied to the society, stand out. Therefore, diverse programs and methods have been developed to monitor indicators of production processes and the characteristics of roduct quality, many of which are supported by statistical concepts. This process encourages understanding and the use of Statistical Thinking (ST), Statistical Engineering (SE), and Statistical Techniques (STe) in businesses, highlighting their importance to quality management and the efficiency of organizational processes. This thesis’s aim was to analyze the use of ST and STe in a sample of industries in the sector of serial capital goods located in the state of São Paulo, Brazil. For that, an exploratory-descriptive survey was conducted with 42 medium and large companies from different segments of the sector. Data were statistically analyzed using descriptive and multivariate methods (cluster analysis, association and correlation). These analyses revealed there is considerable space to diffuse Statistical Thinking and Statistical Techniques in these companies, as well as revealed a lack of training in statistical principles and techniques, the main obstacles to the systematic application of these techniques, and the lack of support on the part of top management. There is evidence that the successful implementation of Total Quality Management (TQM) and Total Productive Maintenance in the industries of sector significantly influences the diffusion of ST and the application of STe; while the use of Six Sigma program especially impacts the application of more complex STe; and ST has the potential to promote the application of STe.

The orexins are hypothalamic neuropeptides involved in an array of functions such as regulation of sleep/wake states and chemoreception to CO2/pH. The Locus coeruleus (LC) is a chemosensitive site and expresses an extensive population of orexin receptor 1 (OX1R). Here we tested the hypothesis that OX1Rs located in the LC participate in the ventilatory response to hypercapnia in a vigilance state and diurnal cycle-dependent manner. To this end, we performed unilateral injections of SB-334867 (OX1R antagonist, 5 mM) into the LC of male Wistar rats and evaluated the ventilatory response to 7% CO2 during wakefulness and sleep in the dark and light phase of the diurnal cycle. Hypercapnia induced an increase in ventilation in all groups compared to normocapnic values. However, the injection of (SB-334867) promoted an attenuation of the hypercapnic chemorreflex during wakefulness, due to changes in VT. In addition, microinjection of SB-334867 decreases the wakefulness time during dark phase. We suggest that projections of orexin-containing neurons to the LC contribute, via OX1Rs, to the hypercapnic chemoreflex during wakefulness in the dark phase.

Generally speaking, the evolution of organizational behavior has been analyzed almost exclusively from the economic and technological transformations point of view. According to this perspective, firms are transformed by market forces as they struggle to adapt to customers’ demands in order to become more competitive and to survive and thrive. This viewpoint neglects the influence of powerful interests institutionalized in society, which manifests themselves inside firms through the actuation of organizational elites. Based on the study of organizational elites and the power relations they establish we are able to achieve a better understanding of factors that determine organizational behavior. With the advent of continuous transformations to which companies have been submitted with the stated purpose of giving them greater flexibility in the face of increasingly competitive markets, the old static organizational structures began to give way to network organizations, more susceptible to restructuring in order to suit economic interests. This flexible organizational environment would require also flexible professionals, averse to excessive specialization, which could hinder them the freedom to move through the organizational network seeking for new opportunities. The changes associated with this flexibility discourse, in turn, may offer opportunities to favoring not declared interests of the organizational elites. In this sense, the subject of our study is how the flexibility discourse might be used instrumentally by organizational elites in their internal disputes for leading positions in companies. More to the point, the question that we propose to investigate is: ‘would it be possible to identify in the behavior of members of organizational elites some evidence of the usage of the flexibility discourse as a tool to compete for command positions within organizations?’ It is not our intention to answer that question categorically, but to advance in the understanding of this topic through a reflection based on theoretical and empirical evidence. In order to seek possible answers we have investigated the careers of business consultants who worked for a multinational consulting company operating in Brazil. We have found that having worked for a renowned business consulting company represents a significant shortcut for executive positions in organizations from several industries, especially if coupled with an MBA title by some prominent American or European business school. This can be taken as an evidence that the flexibility discourse is aligned to the interests of organizational elites, to the extent that it legitimizes their claims to rise to positions of power in organizations without going through the lengthy path required by the assimilation of specific knowledge of each type of activity or industry.

The Brazilian government has implemented policies and procedures that govern the actions of the society and entities own state in order to promote greater environmental awareness and actions that mitigate negative environmental impacts, such as the Environmental Agenda program in Public Administration (A3P). The adoption of an Environmental Management System (EMS) formalized by an educational institution can contribute to the awareness and the spread of the importance of environmental issues. The Campus Uberaba of Federal Institute of Education, Science and Technology of Triângulo Mineiro (IFTM - Campus Uberaba) is an educational institution that seeks to establish an environmental management system. This study aimed to carry out an environmental diagnosis in IFTM - Campus Uberaba as a way to aid in the definition of social and environmental responsibility policies and the implementation of an EMS in the institution. Exploratory study was conducted in order to identify existing environmental standards to which the IFTM - Campus Uberaba is subject, as well as meet other voluntary environmental management practices by public institutions and / or higher education that could serve as a model for the institution. From the management reporting analysis, environmental control report, bidding notices, pedagogical projects of the courses offered by the institution, and also through direct observation, the main environmental aspects and impacts from campus´s processes and services have been identified, and existing environmental practices. It was verified that, over time, there was an intensification of government actions to mobilize their public institutions in the adoption of sustainability and environmental responsibility criteria. In IFTM - Campus Uberaba, environmental impacts information were identified on the physical, biotic and socioeconomic means and the action already present of a solid waste management project and a joint selective collection program. It was observed that the bidding notices practiced on campus do not include sustainability criteria in the procurement of materials and services and, for the discard practices of the institution, the legislation that deals with it has been obeyed. It was also observed that it is prevalent the use of virgin paper and disposable cups in the institution. As for the teaching practice it was found that the environmental issues, social and environmental responsibility and sustainable development are covered by most courses. The analysis of the survey of voluntary environmental management practices of some higher education institutions and other public institutions has observed that for the IFTM - Campus Uberaba assume its social and environmental responsibility are necessary several actions of its senior management to motivation and conviction of their community. From these findings it was concluded that the IFTM - Campus Uberaba may adopt changes and fixes in existing shares to fit the criteria and environmental requirements in voluntary standards, either by ISO 14001 or as the A3P, which should promote a management participatory, enhancing existing initiatives and involving the whole community.

This research presents an ethnography of care’s network. I describe the mode of operation of an intersectoral management for drug users, as from a fieldwork in public health equipment in São Bernardo do Campo (SP). The construction of networks for reception and support care (acolhimento e cuidado), appointment (encaminhamento) and treatment for this targeted public is the empirical question that guides this research. The ambiguous figure of drug user (both patient and defaulter) resonates in the public policies for this population. For this reason, the networks both care as well as enclose these subjects at the same time. The ethnography of network in the health sector explores the challenges and dilemmas that these intersectoral management apparatus evoke. I present the issues that revolve around the network’s organizational model that is formulated by standardization of policies and the universalization of principles, but in practical terms they are invented according to the occasions. I also raised the dilemmas of how workers throw themselves on the challenge of tying partnerships, doing maintenance, seeing the size of the network, tracking the movement of people, information and documents, and planning their growth in the territories. Such developments matches the dilemmas of an assistance project that aims to take care of people in freedom, accomplishing the democratic and humanistic precepts, but intends to monitor the movements and pursue many traces.

In this work, it was developed a procedure for the determination of metals in cosmetics, employing the techniques ICP OES, GF AAS, LIBS and LA-ICP OES; in addition, it was explored the potential of chemometric tools. For the determination of Cd, Co, Cr, Cu and Ni by ICP OES and Pb by GF AAS in eyeshadow and lipstick samples, it was developed a sample preparation method using diluted nitric acid and a hot block. For the optimization of chemical parameters of sample preparation and operating parameters of ICP OES, it was used factorial design and for data analysis and selection of the best working conditions, the desirability functions were employed. In total, it was analyzed 30 samples of cosmetics (21 eyeshadow and 9 lipstick), of different colors, brands and from different countries (Brazil, USA and China). These samples were analyzed in triplicate and with standard addition to perform the recovery calculations. The analyzed samples showed concentration of Cd and Pb within the limits set by the laws, however, 7 eyeshadow samples had concentration of Cr and Ni above than 5 g g-1. In the case of lipstick samples, all values were below this safe limit. All samples analyzed by ICP OES and GF AAS were also analyzed without sample pretreatment by LIBS. The values obtained in the quantitative analysis were employed in the development of supervised classification models such as the KNN and SIMCA. For the obtainment of these models, data of children´s cosmetics samples were included. The classes considered in the models were: below and above the legislation, with a limit set at 5 mg kg-1, according to the recommendations in the literature. In addition to analysis of eyeshadow and lipstick samples, it was explored the potential of the techniques LIBS and LA-ICP OES along with chemometric tools for exploratory analysis of sunscreen samples. The results were obtained for three different equipment (two LIBS and one LA-ICP OES), and several models employing principal component analysis (PCA) were generated. The signals profile of Al, Ni, Ti, and Zn were analyzed and the results obtained between the three equipment were similar.

The current educational policy postulates the inclusion of all children at regular schools, respecting their needs and peculiarities. However, such care is not always provided. Due to language access difficulties, the deaf students are excluded from the teachinglearning processes. It is extremely important to develop pedagogical practices focused at these individuals‟ needs. These initiatives should facilitate the acquisition and use of Brazilian Sign Language (Libras) at school. Actions toward this goal became mandatory with the publication of the Brazilian Federal Decree 5.626/05. This study is articulated to a schooling program called Inclusive Bilingual Program, which conducts researches and follow-up actions as part of an inclusion program for deaf students at a regular school in São Carlos/SP. Its main focuses are to develop the bilingual education for deaf students and to insert Libras at school environment, applying appropriate methodologies and teaching practices. The aim of this work is to propose an evaluation system for deaf students written language analysis and follow-up, focused at Libras users. Three studies were carried out in order to create, test and apply the evaluation system proposed. The performance of each student was analyzed concerning their Portuguese Language registers. This study can contribute to the educational system, which needs instruments to evaluate its aims, actions and strategies for supporting the bilingual education of deaf people.
