The concept of customer experience has been widespread in different industrial and service sectors as a positive customer experience in relation to a product, brand and services has the ability to increase levels of satisfaction, loyalty and word-of-mouth communication. In the health area, there is a clear concern with the patient's experience. This is a multidimensional concept focusing on the cognitive, emotional, behavioral, sensory and social responses of patients in relation to direct or indirect interactions with the company providing health services. In the literature on this topic, one of the challenges is how to measure the patient's experience. This assessment becomes more necessary in the context of a pandemic such as that experienced by many countries, including Brazil. Thus, this research aims to measure the impact of the COVID-19 pandemic on patient experience practices in Brazilian hospitals through a closed questionnaire. To achieve this objective, two research methods were adopted. The first refers to a scoping review in the literature on models for measuring the experience of adult patients in general hospitals. The second method refers to conducting a survey type survey by applying a questionnaire on the impact of the COVID-19 pandemic on patient experience practices in Brazilian hospitals. Data were collected for a valid sample of 88 health professionals and / or hospital managers. Among the results of the research, we highlight the identification of the main instruments (HCAHPS, PPE and QPP) and variables (communication and information, work team and care and safety) used to assess the patient's experience. The results also show the relationship of the hospital's response capacity to coping with COVID-19 with the performance of the current and future hospital and with the patient's experience practices and, these, with the performance of the patient's experience. It also shows the positive moderating effect of patient guidance on the hospital's present performance.

Solid waste, lack of basic sanitation and water pollution contribute negatively to the quality of life of cities and their inhabitants, in addition to the deficiency of public policies aimed at local sustainable development, as the vast majority of cities suffer without adequate infrastructure. The universalization of public services is distant considering that in the 21st century, 47% of the Brazilian population does not have basic sanitation and 16% does not have treated water. Eco-barriers are structures that aim to capture all types of floating waste improperly disposed of in water courses. In view of this, the general objective of the present study was to evaluate the impact that eco-barriers have on water quality and reduction of water pollution. The amount of floating solid waste collected in the periods from October 2019 to March 2020 was determined from the installed eco barriers, such as the water quality of the stretches evaluated with the presence of macrophytes (Eichhornia crassipes) and application of the Callisto Protocol to measure the degree of impact on the points assessed. It was observed through the protocol, that points 1 and 2 had the same score (20 points), which characterizes the stretches as impacts through mainly anthropic actions. In point 3, a slightly greater presence of vegetation was observed on the banks of the Ribeirão, in addition, there was no presence of oil in the water and no evident odor, classifying it as an “altered” section with 26 points. With regard to collected waste, 2018 was the year where the lowest monthly average of collection (294.9 kg) was obtained over a six-month period. The year of 2019 stood out, with just over a ton and in 2020, even considering the months of January, February and March of evaluation, the volume corresponded to 65.03% of the year of 2019. With regard to hydrological monitoring , there were statistically significant differences in the electrical conductivity parameters and total dissolved solids. Eco-barriers are functional structures because they prevent floating residues from reaching the Jurumirim dam and compromise the fauna, flora and all natural habitat. Regarding the use of Eichhornia crassipes, the values show that there is apparently an improvement in water quality, however other studies are essential with the increase in the sampling period and frequency

Metacognitive knowledge refers to the information that the subject holds about his own cognitive systems and also about cognition in general, being considered as the segment in which the knowledge of the world is stored and the human being is understood as a cognitive creature. It is through this knowledge that the individual controls his resolution behaviors, enabling him to recognize and characterize problem situations, and to choose the resolution strategy that best suits him. Impression management, on the other hand, is the process by which individuals attempt to control their actions in order to adapt to and shape the impressions that others construct about them. One technique recently included in this process is humblebrag, composed of a combination of the strategies humility, complaining, and bragging. However, studies in this field have evidenced that demonstrating sincerity in speech is essential for building a positive image. The main objective of this doctoral dissertation is to investigate evidence of the relationship between metacognitive knowledge and impression management, as well as to examine humblebrag as a self-presentation technique: whether its elements interfere in its process, and if so, which ones. It is first hypothesized that metacognitive knowledge has a direct influence on impression management. The second hypothesis is that humblebrag is moderated by the strategies that compose it, the motivations of self-presentation and the speaker's sincerity and ability to convince. Thus, this thesis is divided into three studies, described in the format of scientific articles. The first manuscript aimed to analyze, by means of a systematic review, studies on impression management and humblebrag. Five references were obtained, the first of which was published in 2015. Main results indicated that complaining and bragging are preferred strategies by the audience when compared to humblebrag. The second manuscript described a pilot study, in which an instrument was developed with the aim of assessing metacognitive knowledge in impression management, and humblebrag and its elements. This instrument was evaluated by three expert judges and applied to 12 university students. Results showed that the instrument is adequate for the constructs it intends to assess. Finally, the third manuscript brought the reformulation of the instrument based on the participants' considerations, and the application of the questionnaire in a representative sample of the instrument's target audience. Results pointed out that during the evaluation of metacognitive knowledge, impression management strategies were indicated, establishing a relationship between the two phenomena. Furthermore, the use of humblebrag, in order to be successful, requires a balance between humble and boastful behavior, and the need to convince the public of one's competence.

Abstract Ichnofossils, studied by Paleoichnology, are structures produced as a result of behavioral and physiological activities of organisms of the past. Fossil tracks (footprints), one of the best-known types of ichnofossils (bioturbations), are produced by the interaction of the animal's autopods with the substrate, the latter being deformed in the process. The shape of the autopods, the conditions of the substrate and the locomotion behavior of the trackmaker directly influence the morphology of the tracks. During the beginning of the Cretaceous, a huge sandy paleodesert covered a large area of the Brazilian territory, giving rise later to the eolian sandstones of the Botucatu Formation. Its main fossiliferous content are the tracks and excavations produced by the animals (vertebrates and invertebrates) that lived in the paleodesert, being the region of the Municipality of Araraquara (São Paulo State) the one that presents the greatest quantity and diversity of ichnofossils. The present work had as main objective the morphological and paleoecological analysis of ichnofossils with affinity to non-archosaurian tetrapods from the Botucatu Formation. The descriptions of the tracks and trackways were carried out based on parameters established in the scientific literature, such as width and length of the tracks, oblique pace, stride, pace angulation, trackway width and rotation of the autopods. Several specimens of tracks with affinity to larger mammaliaformes have been described and analyzed, and a new ichnotaxon, Aracoaraichnium leonardii, has been defined. It was possible to determine that the trackmaker of these larger tracks belonged to a different species than the trackmaker of the Brasilichnium tracks, and not an advanced ontogenetic stage. In this way, the trackmaker of A. leonardii represents a new component in the ecological structure of the Botucatu paleodesert. It is inferred that the trackmakers of this ichnotaxon could feed on invertebrates or plant material, depending on the availability of resources, being potential competitors of the trackmakers of Brasilichnium. Tracks with affinity to Lepidosauria (lizards) were also described and analyzed for the first time. Such tracks are pentadactyl, with curved digits. The digit I is directed to the inside of the trackway and opposite the digit V, which is in a posterolateral position. Marks attributed to drag and contact of the tail on the substrate were identified. The icnotaxonomic attribution was tentatively made to the icnogenus Rhyncosauroides, and future analyzes based on new, better preserved specimens may elucidate this issue. From the analysis of the trackways, it was possible to identify three distinct locomotion behaviors, being the typical cursorial gait, a gait where the footprints are rotated in the same direction, diverging from the trackway’s midline, and one where the producer makes stops. The recognition of a new trackmaker with a lizard-like affinity increases the complexity of the ecological web of the Botucatu Formation and contributed to the understanding of the distribution and niche occupation of these animals in the Lower Cretaceous.

In this master's thesis, we study the recent results about global existence for the integrable dispersive Hunter–Saxton equation in a periodic domain. Firstly, the local well-posedness of the Cauchy problem of the equation is established in $H^s(\mathbb{S}) $, $ s \geq 2 $, by applying the Kato method. Then, based on a sign-preserve property, a global existence result is obtained for the equation in $H^s(\mathbb{S}) $, $ s \geq 3$. Moreover, the obtained result is extended to some periodic nonlinear partial differential equations of second order of the general form.

This thesis aims to understand the aspects that involve the condition of rural youth life, as well as the everyday circulation, life projects and meanings of the school, taking the case of the rural youth of the city of São Carlos/SP. It was intended to understand and analyze what are the macro and microsocial aspects that involve the condition of youth life, limiting and/or enhancing the respective living. Thus, the objective was to determine how the everyday circulation of these young people is constituted, considering the traffic in the territories and communities; their life projects; and, finally, the meanings attributed to the school and how it marks such life projects and everyday circulation. With this study, we aimed to contribute to a critical analysis of the phenomena that pervade this population, in favor of solving problems that restrict their participation and social insertion. In addition, it was also thought to encourage advances in research enrolled in the field of rural youth and education, responding to a shortage of productions on the subject. For this purpose, the investigation was based mainly on theoretical and methodological excerpts from a Marxist basis. It is a research that dialogues with assumptions of participatory research and social occupational therapy, considering that it was based on a study carried out by an occupational therapist researcher. For the collection/production of data, “Workshops of dynamics, activities and projects”, “Individual and Territorial Follow-up” (through interviews, informal conversations, joint circulation and activities) and Questionnaire, directed to the production of oral narratives, written, imagery or audiovisual, which were later analyzed in their content. According to the data, these are poor young people, members of class-who-live-from-work. These people like to live in the rural territory, above all, for the tranquility of the space, however, the conditions that permeate the limitations of access to public and private services (health services, education, transport, leisure spaces for meetings, sociability and fun) mark the feeling of isolation in their experiences. In the context of everyday circulation, they point out that the central limits are the absence of transportation, the lack of money and, sometimes, barriers imposed by parents or guardians. Young people are able to find escape points to overcome these limitations, but within that the school still remains the central space that produces everyday circulation, in the coming and going, in the promotion of meetings, fun and sociability, although little dialogue with those indicated needs, which creates conflicts. In relation to life projects, young people build projects that have as main focus the insertion in the labor market and higher education, which are generally associated. Projects are often more tied to the most urgent needs (thus called projects-necessity), such as getting a job to help parents financially, paying for college or courses and having greater autonomy in local territory, especially for young people most affected by poverty. Other projects are aimed at more distant futures, linked to dreams (the projects-dreams), such as being more socially recognized professionals, getting to know other countries and cultures and more, which go beyond the locality. Thus, it is identified that many life projects refer to projects for wider circulation, comprising beyond the local community, which often demands actions that the rural territory does not offer, since the intent is incompatible with staying in that territory. Finally, there is an urgent need for public policies for rural youths based on the emancipatory everyday circulation, in which the school, especially in the context of high school, has the potential to become a center of creativity, which in articulation with other equipment in the rural territory, can expand the experience of life and the chances of coming and going freely - producing the being more of these young people.

The research question about school libraries within the scope of the theoretical trajectory of consolidating the field of research in Information Science (CI) has been contextualized through the presentation of concepts and general definitions about the research developed in School Libraries. Thus, a basic research has been carried out based on a descriptive analysis of the context that represents the school libraries in private educational institutions in São Carlos, highlighting the situation of the library at Escola Educativa, for which an experience report of the functionalities of the school library in a teaching cooperative was drawn up. The objective was presenting general concepts and definitions that punctuate the understandings assumed in CI research in a School Library, identifying and describing census data in School Libraries in Brazil. It also aims presenting quantitative data in school libraries and private educational institutions in the city of São Carlos; describing the educational management model either in Cooperatives or at Escola Educativa, as well as analyzing the context of the constitution of school libraries in the city of São Carlos, in private institutions, highlighting the case Escola Ecucativa. The educational library at the Cooperativa de Ensino Educativa was participative and active in the formation of the student body, complying with the current legislation and being adequate to the proposed Educational Management model, where the benefit of this type of teaching cooperative is to be participatory.

Scientific dissemination includes the transmission of scientific knowledge produced in educational and research institutions, for society, especially for non-specialist citizens. In this perspective, university libraries can play a fundamental role looking for ways to present the potential of science as an element of social transformation. The objective of this research was to investigate the performance of the university library, as an active actor in scientific dissemination, through cultural action. The research method used was ex post facto. The units of analysis were the Community Library of UFSCar and the National Institute of Science and Technology of Hymenoptera Parasitoids (INCT Hympar). It was possible to achieve the following results:1] identification of cultural practices and initiatives, involving scientific dissemination to non-specialist citizens; 2] identification of benefits for the library, for the research group and for society. It is considered that through cultural initiatives, multicentric Brazilian research centers, through university libraries, can have a closer relationship with society, promoting the appropriation of scientific and technological knowledge by the lay citizen, through scientific dissemination.

It is consolidated that the machining of titanium alloys poses obstacles due to their low machinability, which is related to the maintenance of mechanical resistance at high temperatures, the low thermal conductivity, the chemical affinity with various tool materials and the low elastic modulus. Due to these difficulties, surface and subsurface problems are recurrent in components of titanium subjected to machining processes, compromising their operation in different applications. Such components are often subjected to severe working conditions and, as a result, require adequate surface integrity parameters for their applications. In order to better understand the influence of tool geometry on the surface integrity of a given titanium alloy and enable the use of different types of tool to increase part quality at the expense of changes in cutting parameters, which affect the productivity of the process, the present work aims to determine correlations between the geometry (clearance angle and nose radius) of uncoated cemented tungsten carbide cutting inserts and the surface characteristics of the Ti-15Mo alloy after turning process. After the tests, according to the results obtained for most of the measured roughness parameters, the small effect of the clearance angle, as well as the significant geometric contribution of the nose radius, whose increase reduced the roughness values, became clear.

The south of Bahia stands out in the conservationist scenario, hosting the largest Atlantic Forest remnants. Consequently, the region has a rich biodiversity, containing taxa that have already been extinct in most of their original distribution. In addition to the great forest remnants, the region includes enclaves of muçunungas, vegetation formations in sandy soils, considered environments sensitive to anthropogenic disturbances. Here we study bird assemblies in the region called Costa do Descobrimento, south of Bahia, between 2011 and 2019, under two perspectives: (i) the influence of landscape changes; (ii) present the first discussed list of muçunungas’avifauna with different structures (grassy-woody - GL and muçununga forest - FM), characterize the use of feelding resources in these formations, as well as the influence of adjacent vegetation formations. In Chapter 1, our hypotheses are (1) native vegetation thresholds of pristine areas be likely to be distinct than sites under long term disturbances and/or more fragmented over a larger chronological scenario for birds; (2) forest dependent (FD) and semi-dependent (FS) species respond differently to patterns of land use; (3) specifical sensitivity patterns are distinct from general patterns studies. We sampled 293-point counts, and 100 were settled across ten different classes of forest cover percentage to generate models for estimating the landscape effects on birds. We defined one buffer (1 km radius) for each point, where we calculated six landscape metrics and three bird attributes. We recorded 340 species; 56 highly sensitive. We confirm that there are higher thresholds in pristine areas; landscapes preserving large remnants of native forest host bird taxa locally extinct from other regions, with many species present only in areas> 60% of native vegetation. This is due to better vegetation structure and a larger set of resources, possibly. Thus, the core area was the variable that showed the highest correlation with the abundance and richness of forest species. We also confirmed that forest FD and FS respond differently to land use; FD species are more sensitive because of their ecological requirements. Our data also revealed specifical patterns of environmental sensitivity. The importance of maintaining 60% thresholds of native vegetation is emphasized, as well as the need to direct efforts to preserve large fragments (≥ 100 ha) in the landscape for the maintenance of more sensitive bird species. In the chapter of muçunungas, in turn, we recorded 216 species; 32 endemics to the Atlantic Forest and 14 threatened with extinction. The most abundant feeding guilds were insectivores (77 species), omnivores (53), and frugivores (32). A total of 109 species were recorded in FM and 183 in GL. Strictly forest birds prevailed in FM (66%), and forest, semi-forest, and open-area species were detected in similar amounts in GL. Similar to restingas, muçunungas are influenced by surrounding environments. There was a predominance of generalist birds, with many species coming from these surrounding environments. Due to the similarities with restingas, it is suggested that similar conservationist strategies could be applied to both environments of the Atlantic Forest.

The licensing of technologies developed by Scientific, Technological and Innovation Institutions - STIs for companies is a theme addressed by several studies, as it is one of the traditional forms of technology transfer. It turns out that the main approach in most of the works, was given to aspects that consider the perspective of the STIs. The perspective of entrepreneurs and professionals representing licensed companies, with regard to how to proceed so that the knowledge generated in universities and research centers has increased the possibility of reaching the consumer market, needs to be further understood. This need arises, among other factors, from the differences of interests of the parties, differences in organizational cultures and aspects related to the impacts on the business due to such differences. This study aims to identify the main factors of effectiveness in the technology licensing process from the perspective of representatives of companies licensed by an STI, establishing correlations with the characteristics of the companies and the technical and commercial performance of the licensed technologies. Therefore, it intends to expand the range of knowledge for innovation managers, enabling the strategic implementation of practices that are more appropriate to the reality in which they find themselves, in the search of an increasing in the number of STI technology licenses for companies and success in the commercial exploitation of products, processes, etc., arising from technologies. As a result of the work, it was found that, according to the literature, technology transfer offices play a leading role in the process, but from the perspective of representatives of licensed companies, technology assumes the main role in the licensing process.

The use of social networks has intensified in recent years, allowing an evolution in the media focused on consumer goods. The presence of digital influencers also plays an important role in the dissemination of brands and products, offering a closer and more reliable relationship with the public. The objective of this research is to analyze the influence of social media on purchasing behavior, exclusively for beauty products, consumers in the city of Sorocaba-SP. Through a quantitative research it was possible to define the profiles and habits of consumers in the city, in addition to understanding how brands and influencers use social media to generate purchase incentives. The information was analyzed statistically considering the influence between social media and purchasing behavior. For the sample analyzed, it was identified that product recommendations and reports by influencers impact the purchase process, a direct influence on decision making for the purchase of products in this segment. In addition to brand loyalty, the public also becomes receptive to try new products and how networks become a communication facilitator for an exchange of experiences and recommendations.

This research has as main objective to generate reflections on the environmental planning process of ecological corridors evidence-based published through the action research methodology. This is the UFSCar ecological corridor, which is foreseen in the last update of the Campus Master Plan, held in 2013. The action research model was used as the main methodology. Criteria for bibliographic analysis of scientific evidence were developed. Regarding the information obtained through scientific evidence, for the groups of organisms affected by the ecological corridor, it is believed that plant restoration, based on species native to the region, favors all groups of organisms. Regarding the type of plant restoration, studies point to passive restoration, indicating only the removal of eucalyptus which, in turn, can be kept in small fractions, which can function as nucleating species for restoration. Regarding the control of brachiariae, the result is divided between the use of chemical control or mechanical extraction, indicating a study that tests which is the best option. The roads are shown to have an impact on biodiversity conservation, but few studies address the effect of firebreaks as an object of study, requiring practical proof. Environmental monitoring of all management actions is essential, using different instruments and methodologies, prioritizing those that best represent the specific needs of the corridor in question. The qualification criteria of the bibliographic sources proved to be valid for selecting the information obtained. Through the applied action research methodology, we were able to reflect more on the research development process, which was positive to generate questions and assessments about the available structure used by us for bibliographic research

Several authors have dedicated themselves to investigating the dynamics of machining operations from different scopes. This type of study is especially valuable when it comes to finishing conditions, as the vibrations in process can significantly affect the surface integrity of the machined components. Turning of steels in the hardened state has gained ground in the metalworking industry as a substitute for abrasive processes. In this case, in fact, monitoring vibrations and controlling different roughness parameters are extremely important, as they can even influence the mechanical behavior of the components in question. This work contains an investigation about the influence of some machining conditions on the vibration of the tool and the surface integrity of the part in hard turning. For this, a specimen of tool steel for hot working type H13 was quenched and tempered made in segmented laps. The experimental procedures are divided into two stages: preliminary tests and new tests. In the former, a conventional lathe was used, a negative tool and, as influencing factors, the rotation of the spindle, the feed and the position of the lap in machining. The vibration signals, measured by piezoelectric tablets, were not able to infer any influence; on the other hand, the triaxial accelerometer indicated the influence of the advance. The roughness parameters, evaluated in a confocal microscope, in turn, showed the influence of the lap in machining. In the new tests, a CNC lathe, positive tool and piezoelectric accelerometers were used, which pointed to a greater influence of rotation and feed on the vibration of the tool. The roughness parameters show the effect of rotation and the position of the lap when machining. In view of the results obtained, it is concluded that this approach can consistently contribute to the improvement of process planning involving the machining of hardened steels. As suggestions for further work, we highlight the study of the influence of dynamic machining conditions on the mechanical behavior of machined components and the evaluation of vibration signals in the frequency domain to enable the identification of the occurrence of the chatter phenomenon.

The beer market in Brazil arouses interests all over the world. With a large volume of distribution concentrated in a few players, the competition for spaces in this market is fierce, and consequently, investment in advertising grows exponentially. Understanding the consumer purchasing decision-making process and knowing their preferences and influences is essential to direct the strategies of these large companies, ensuring an adequate return on investments in Marketing. The objective of the research is to understand the buying behavior of the beer consumer, identifying the influences in the purchasing decision-making process, in particular the impact of brand communication in this process.

The family is considered the main assistance, interaction and support network in old age. However, the effectiveness of this protective factor is not always observed. It is known that with advancing age, the chances of developing diseases and dependence increase, intensifying the needs for support and care. Social safety nets play an important role in maintaining family and community ties, contributing to the health and well-being of the elderly. This study aims to analyze a constitution of family arrangements of elderly people registered in a Reference Center for Social Assistance and its relationship with social support, fragility, quality of life and cognition, considering two moments of data collected in the period from 2012 to 2019. In addition to analyzing, from the perspective of the elderly, possible tensions in the family context. This is a longitudinal study using mixed methods with concomitant triangulation that continued the research carried out between 2012 and 2016 with 247 elderly people. Data collection occurred through a home visit with an approximate time of one hour. Instruments were used to obtain sociodemographic data, Edmonton's Fragility Scale to identify frailty; The Montreal Cognitive Assessment for screening cognitive impairment, quality of life (Whoqol-bref and the old), building a Genogram and Ecomapa to assess family and social relationships through tapes. Quantitative data were analyzed using descriptive statistics and the Wilcoxon and Mann Whitney comparison test, those with a qualitative approach using content analysis based on Bardin, using dialectical materialism as the theoretical framework, and Agnes Heller's concept of daily life. 84 elderly people participated in this study. It was noticed that the majority remained living with a family member (73.8%), 54.7% increased their relations with the community. The fragility and non-statistical cognition related to the type of arrangement, however, elderly people who lived alone had worse quality of life in the physical (p0.044) and psychological domains (p0.031) and better scores in relation to the total Whoqol-old ( p0.036). Elderly people who lived with young grandchildren worsened in the social relationship (p0.047) and Whoqol-bref (p0.029) domains, and improved in death and dying (p <0.001) and Whoqol-old (p0, 019). Living with a spouse only worsened the functioning of the sensory abilities (p0.022) and improvements in the domain death and dying (p0.028). Through the categories “Relational processes of the elderly with the family”, “Changes in the elderly's family configuration”, “Support and social support offered and received”, it was observed that family arrangements are dynamic, sources of tensions, conflicts and relationships of interdependence. It is concluded that regardless of the type of family arrangement, the relationships built between its members are essential for the provision of support and support in old age, interfering in their health conditions. It is urgent to reformulate public policies aimed at this specific population in order to provide quality services to this social segment that is growing.

In this work, SnO2 nanowires (NW) were grown by the Vapor-Liquid-Solid (VLS) method and used to build single NW FET devices. As-grown samples went through structural and morphological analysis and seven single NW devices were built, with a back-gated FET architecture, by direct photolithography. SnO2 NWs grown by VLS method presented the desired tetragonal structure and monocrystalline character, inspected by XRD and HRTEM techniques. In addition, the as-grown samples morphology of a NW with lengths of tens of micrometers and cross-section mostly displaying rectangular geometry were assured through SEM images. The device fabrication process by direct photolithography was proven to be efficient to build the back-gated FET architecture devices with great electrical contacts quality. Single SnO2NWFET’s transport properties were explored, where on/off ratio, mobility and carrier density parameters were extracted, resulting in values around 105, lower than 0.1 cm2/V and in the order of 1019/cm3, respectively. Schottky barrier heights were estimated, considering the gate bias as grounded and room temperature, and Φ_Bn values between 0.41 and 0.75 eV were found. Afterwards, different conditions were analyzed: the device (1) under positive gate bias (V_G>0) and no applied source/drain bias (V_DS=0); (2) V_DS>0 and V_G>0; (3) V_DS<0 and V_G<0 and (4) V_DS<0 , V_G<0 but under UV illumination. Regarding the latter, all devices presented UV induced ambipolary effect, where on/off states ratio with values of the same order were obtained and ranged from 1.1 to about 19.3. A simple band model to explain the observed behavior, i.e., describe how both types of carriers can contribute to the final current depending on the biasing was proposed. Ambipolarity is one of those effects that may direct its use for specific purposes, where a controllable separated unipolar mode can be achieved in one single device. Furthermore, the devices were tested as UV sensors and presented satisfactory results: as a UV photodetector, the acquired I_on⁄I_off ratio was found to be of the order of 〖10〗^4 for all devices investigated. In addition, rise time was found to range 0.56 s < τ_r< 0.63 s, whereas the decay time 0.54 s < τ_d< 0.75 s. According to those results, one can assure their huge feasibility as a UV sensor.

This research has proposed to study the contribution of semiotics to the cataloging of comic books. The comics stand out as an object of research, considering the alignment of questions and visual and verbal values, which are intrinsic to them, as well as the process of defining the context of the scenario involved in the story as important elements for the retrieval of information. Thus, the general objective is to evaluate the contribution of semiotics in the cataloging of comic books. The research, of an applied nature, has presented a qualitative approach and exploratory objectives. Systematic mapping of literature was adopted as a method for bibliographic research, and the Content Analysis was used to analyze the data. As a result, it is understood that semiotics and semiology might contribute to the cataloging of comic books, in theoretical-conceptual and methodological aspects. In this perspective, cataloging has been seen as a semiotic process that permeates all stages of Organization and Representation of Information in comics, from the representation process (thematic and descriptive) to the search and recovery by users. It is observed that the semiotic narrative, discursive and cultural currents might contribute to the cataloging of comic books, mainly in the processes of reading, description, and representation.

The idea of social innovation (SI) stands out today, but when linked to active aging, there is a very large gap in knowledge and practice, especially in Brazil. In the face of this unexplored theme, this research aims to identify and analize SI initiatives focused on active aging in the city of São Carlos-SP and north region of Portugal. This research used a theoretical-empirical methodology and a multi-case study aimed at identifying SI initiatives linked to active aging and quality of life. In addition, a study of the state of the art of SI and active aging was carried out to understand and update itself on the productions developed. The project referring to this research was approved by the Research Ethics Committee - CEP / UFSCar (Opinion nº 3,350,844). The results and discussions point to the existence of well-consolidated SI initiatives for active aging in Portugal, mainly due to the support for this demand in the country and on the European continent. In São Carlos, the initiatives identified, despite not calling themselves SI, aim to meet the demands associated with aging in an innovative way. In addition, this study shows the relevance of research on the theme of social innovation for active aging in the Brazilian context, since there is a lack of knowledge on this theme and there are no public policies for social innovation in Brazil. The final considerations, on the other hand, present reflections and possibilities to expand this theme for its diffusion and incentive to social transformations.
