In this thesis we classify the isometric immersions f : Mm ^ Sm+p x R with m > 3 P < m — ^d c < 1, where Mm denotes a Riemannian manifold with constant sectional curvature equal to c. We obtain partial results on the classification of isometric immersions f : Mm ^ Hm+p x R with m > 3 P < m — ^d c < 0, We also characterize the hvpersurfaces f : M3 ^ Q4(c) for which there exists another isometric immersion f : M3 ^ L4, where Q4(c^d L4 denote a 4-dimensional space form of constant sectional curvature c and the 4-dimensional Lorentz space, respectively.

Urban solid waste management (MSW) is a growing challenge for municipal administrations in view of their increasing quantity and complexity. In Brazil, the National Solid Waste Policy (PNRS), approved in 2010, became a reference to foster local public policies, incorporating the concern with sustainability. Some authors have proposed sustainability indicators (IS) to evaluate selective collection (CS), since the sector lacks tools to assist in the decision making and more sustainable monitoring of waste picker organizations. The general objective of this research is to evaluate the use of indicators to characterize the sustainability of selective collection of MSW, having as object of study the cities of Araraquara and São José do Rio Preto. The research was based on the evaluation of PNRS, recycling, general aspects of SC in Brazil and identification of IS for selective collection. For the application, the IS sets, proposed by Besen (2011), were defined as the most appropriate for the evaluation of the SC and of the pickers' organizations, once they were constructed and validated in a participatory way. In 2014, the selective collections of the two municipalities investigated were monitored. The comparative result showed significant qualitative and quantitative differences in the execution of the SC and in the management of waste picker organizations, especially in the operational aspects. To apply the IS, some meetings were held in the two municipalities surveyed. These included municipal managers, technical staff and members of waste picker organizations. All proposed indicators were applied and evaluated, and some, due to difficulties in data collection and lack of proper monitoring, were only estimated. Based on the results of the IS, two sustainability matrices were built, one from the municipal SC and the other from the collector organizations for the two municipalities. The comparative result showed significant qualitative and quantitative differences in the execution of the SC and in the management of waste picker organizations, especially in the operational aspects. To apply the IS, some meetings were held in the two municipalities surveyed. These included municipal managers, technical staff and members of waste picker organizations. All proposed indicators were applied and evaluated, and some, due to difficulties in data collection and lack of proper monitoring, were only estimated. Based on the results of the IS, two sustainability matrices were built, one from the municipal SC and the other from the collector organizations for the two municipalities. The result of the IS application made it possible to calculate the respective sustainability indices. The index calculated for selective collection reached the favorable range for sustainability for both municipalities. For waste picker organizations, the Araraquara index reached the very favorable range for sustainability and, in São José do Rio Preto, the favorable range for sustainability. The similarity in sustainability indices for the two municipalities differed from the observation of CS monitoring in the field. The research concludes that it is necessary to build new IS sets and improve the evaluated IS set to improve the more sustainable management of selective collection with participatory social inclusion.

Autonomous mobile robots are a special category of robots designed for performing tasks without the intervention of human beings. Some robots are designed to perform tasks in completely inhospitable environments such as the earth´s subsurface, the ocean depths or spatial exploration. In order to consider a robot as autonomous, a fundamental premise is to have self-adaptation capabilities. Over the last years, the advances in technology allow the development of self-adaptive systems, which are able to manage themselves to recuperate from faults or even change their behavior and structure in order to improve the quality of the delivered service. A critical point when building any software is its architecture, i.e., its structural organization in a set of interacting components. In this context, reference architecture is a technique that is well known for combining the best practices, patterns and strategies for building and standardizing domain specific software. Nowadays, there is a lack of studies presenting reference architectures for structuring self-adaptive software of mobile robots in order to decrease maintenance efforts. A number of studies claim that self-adaptive systems are based on the control theory and, more specifically, on the use of control loops in their architecture to perform adaptations. Therefore, this master thesis proposes SARAMR, a control loop-based reference architecture whose goal is to make maintenance activities a more productive task. The employment of the architecture divides the whole system in two modules; base application and adaptation module. The adaptation module encompasses the control loops and the base application is further divided into three other components: environment, behaviors and the electromechanical part. SARAMR was qualitatively evaluated by means of the development of two applications: a self-adaptive wall follower mobile robot and another conventional one to performing monitoring in in-door environments. Next, some maintenance activities were created to investigate the effort of applying them. We have observed that the separation of concerns of our architecture allows new components to be added causing less impacts than in systems developed in an adhoc way.

The populations of Neotropical inland fishes have the distribution of their genetic diversity influenced by historical and recent biogeographic factors. Natural barriers such as the formation of waterfalls can disrupt gene flow between populations upstream and downstream. In addition, river fragmentation by hydroelectric dams also impacts on gene connectivity and, moreover, it exposes population to more intense evolutionary forces, such as genetic drift. The effects of habitat fragmentation are more pronounced in migratory species, which move large distances to reproduce. Among these species, Pseudoplatystoma corruscans, a piscivorous catfish, plays an important ecological role as top predator. In addition, this fish represents the main income for thousands of riverine families. Understanding the influence of historical factors on the population structuring is important for species conservation, because it helps in decision making, such as the determination of management units and guidelines for conducting restocking. On the other hand, analysis of recent factors such as river fragmentation can indicate the impact of habitat fragmentation on the population viability, since smaller populations show greater effects of genetic drift and inbreeding. Having said that, we have analyzed the influence of historical and recent events on the genetic diversity distribution of P. corruscans. For historical events, we collected samples of P. corruscans in all basins of its natural occurrence (São Francisco, Paraná, Paraguay and Uruguay) and used markers with slow mutational rates (S7-íntron1, CITB and D-loop). For recent events, we used microsatellite markers, with high mutational rates. We collected samples in four sections of different sizes of rivers bordered by dams (Grande, Verde, Paraná and Paraguay). The mitochondrial markers indicated the existence of two groups, one in the São Francisco basin and another in the Prata basin (Paraná, Paraguay and Uruguay). The three genes analyzed showed private haplotypes for populations in the São Francisco basin, although S7-íntron1 marker has indicated the existence of only one clade for all basins. These results indicate that the geographical separation between San Francisco and Upper Paraná promoted genetic differentiation between populations of the two basins. On the other hand, the “Sete Quedas” fall, which historically separated the Upper Paraná and Paraguay basins, was not enough to promote population structuring. Probably the two basins were connected by headwaters. Thus, we suggest that conservation efforts are earmarked for two large basins (São Francisco and Prata), with a special look to Prata basin, since the species is threatened with extinction in the Uruguay basin, addition to the large number dams present in the Paraná basin. Regarding the river fragmentation caused by dams, smaller river stretches had lower genetic diversity and greater kinship between their individuals, which can result in lower population viability, since there is an increase of inbreeding depression and loss of adaptive genetic diversity. We therefore suggest that studies with other species are performed to determine the stretch minimum size in which the populations of migratory fish are viable, providing guidelines for the construction of new dams.

The improvement in the delivery reliability performance in Make-To-Order (MTO) companies has been becoming an important competitive criterion in the recent market context. Thus, it gets clear the importance of researches able to present tools to help the identification of enhancement opportunities in the matter of delivery reliability. The identification of opportunities requires a structure of diagnosis of the recent situation. However, depending on the performance problem to be diagnosed, a theoretical understructure based on specific scientific knowledge is needed. This work presents the framework developed by Soepenberg et al. (2012c) based on Workload Control (WLC) concepts. Such framework is composed by a structure for the diagnosis process of the reliability performance that allows browsing from the obtained performance to the subjacent causes related to Production Planning and Control (PPC). The aim of the present work is to present the WLC as well as the diagnostic tools with the purpose of elucidating their applicability through the framework developed by Soepenberg et al. (2012c) in a real context through a case study. The results of the case study indicated that the framework is a key instrument for diagnosis due to the accuracy by which it defines the causes of delays of the orders related to the PPC decisions. The application of the framework indicated that the lack of spare parts is the most impacting factor on delays, however this is not a cause only related to the company PPC decisions, but to external factors that are out of the company’s reach. Another result obtained is the verification that most of the orders are concluded before the date set. This is due to the lack of accuracy in the definition of the delivery dates and to the estimative mistakes of the capacity to be used for the maintenance of each part number, whose responsibilities rely on PPC.

In this work we obtain a reduction of the vectorial Ribaucour transformation that preserves the class of submanifolds with constant sectional curvature of space forms. As a consequence, a process is derived to generate a new family of such submanifolds starting from a given one. We prove a decomposition theorem for this transformation, from which the classical permutability theorem for the Ribaucour transformation of submanifolds with constant sectional curvature follows. Given k scalar Ribaucour transforms of a submanifold with constant sectional curvature, we prove the existence of a Bianchi k-cube all of whose vertices are submanifolds with the same constant sectional curvature, each of which is given by means of explicit algebraic formulas. A further reduction of the transformation is shown to preserve the class of Lagrangian submanifolds of dimension n and constant sectional curvature c of complex space forms of complex dimension n and constant holomorphic sectional curvature 4c. In particular, explicit parametrizations in terms of elementary functions of examples with arbitrary dimension and curvature are provided. A decomposition theorem and a version of the Bianchi cube for this transformation are also obtained.

The human being interacts constantly with ecosystems and uses various goods and services from them. These goods and services are called "Ecosystem Services" (ES) and the benefits from these services are called "constituents of well-being." The agroecosystems are modified so that there is greater provision of certain ES, such as food, raw materials and fuels. However, to provide these ES, the agroecosystems need others ES to suits their needs, thus maintaining its production capacity. In agroecosystems, farmers are the main managers of natural resources, influencing the management directly. Therefore, understanding how farmers perceive and interact with natural resources is of great importance. This study aims to evaluate the perception of farmers on the ES, through semi-structured interviews. Analyzing ES perceived by farmers, their relationship with the agricultural practices used, with the impacts caused by agriculture and socioeconomic factors. The farmers interviewed were all in agroecological transition process and belong to settlements Ipanema and Horto Bela Vista, in the municipality of Iperó, near Ipanema National Forest. Within the results, it was observed greater perception of the production ES in relation to regulatory and cultural ES. As well the relevance of the educational level in the perception of ES. Increased awareness of the ES by farmers is of great importance, since it may well assist in agroecological transition.

This study describes the genetic diversity of a population of Hoary foxes (Lycalopex vetulus), animal whose habitat is in the physiognomy of Cerrado, one of the most fragmented and disturbed areas of Brazil. To this end, 33 individuals were captured in a region of cattle ranches in northern Minas Gerais and southeast of Goiás. We amplified 10 microsatellite loci. Our data reveal that these loci are useful in the study of genetic conservation. The genetic diversity present in individuals captured in this study, can be considered high, despite the high degree of fragmentation in the area. The effective population size calculated in this study shows that the genetic diversity supported by the animals studied is representative of a population of approximately 1,300 individuals. We conducted kinship estimates using three methods, one by reading the genotype by software, another through information obtained by field observation studies and a final one, used only when the first two were at odds, based on par visual analysis to analyze all alleles of all loci. With the aid of GPS, the distance between related individuals, paying attention to possible gender’s variation. We conclude that the fox is able to move long distances (over thirty kilometers) and that apparently there is no difference in the male and female dispersal capacity.

This Master s thesis shows a solution for splitting MPTCP subflows in an Openflow network. MPTCP is a network protocol designed to branch a single TCP connection into many subflows. The main idea is to forward subflows th- rough disjointed paths. Commonly, ECMP protocol is adopted together to split flows through distinct paths. Nevertheless, there are many issues that shows that ECMP is not pareto-optimal, such as: ECMP can easily set two subflows from the same TCP connection on the same path and/or set a distinct forward and back forward route to the same subflow. To solve these issues, it is designed MultiFlow, a module which uses a controller for guarantee multipath routing by setting subflows from the same MPTCP connection so that such subflows are forwarded through distinct paths. MultiFlow is evaluated in experimentation where is analyzed throughput and resilience comparing it with Spanning-Tree (STP) and ECMP. The experiments were done by using Mininet: An OpenFlow emulator for experimenting with a set of topologies.

This work presents a didactic proposal for the classes of affine and quadratic functions in elementary school. From our experiences in the teaching profession, we noted that the study of this content requires experimentation and contextualized activities. The study of affine and quadratic functions in basic education is of great importance for abstraction capacity development, solving practical problems and helps to get skills of comparing results, recognizing the characteristics of these functions. Our work is not intended to define affine and quadratic function, but to develop the perception ability of the results that leads to graphs and charts building and can be confirmed using the GeoGebra software. This activity was implemented in two classes of the ninth year of elementary school at Colégio Batista Brasileiro in Bauru. To do this we need four classes of 100 minutes and 1 class of 50 minutes. This is a didactic sequence that requires the use of computers and of the GeoGebra software

In this work we study conditions for the validity of the analogue of Mergelyan’s theorem for continuous solutions of a type of locally integrable vector field. On a domain in the plane, we consider a vector field L that has a first integral on of the form Z(x, t) = x + i'(x, t), where '(x, t) is a smooth, realvalued function. Given a continuous solution u of Lu = 0 on , our first objective was to find conditions on and Z for the validity of the factorization u = U Z, where U 2 C0(Z ()) \ H(int{Z ()}). We will next study this factorization on the closure of . We assume that u 2 C0( ) and that the boundary of is real analytic, then we show in which cases the condition Z(p1) = Z(p2) implies that u(p1) = u(p2), for p1, p2 2 . The cases are divided according to the geometry of the boundary in the points p1 and p2. When is a compact set and u = U Z on , we obtain that u is uniformly approximated by polynomials of Z on .

Nowadays the aging phenomenon has been studied by many researchers because of the characteristics and relevance of the demographic transition and the impact on public policy. Because of this phenomenon, it is considered extremely relevant to the broad scientific production developed view, and in this study we chose to focus on what has been produced in federal universities. This study aims to analyze the Brazilian scientific literature on the topic aging and administration / public management, from scientific publications (qualis A1 and A2 of interdisciplinary and administration areas) and on the registered research groups in groups Directory Research CNPq Brazil (biological areas, health, human and applied sciences). It is a social and exploratory and descriptive study of document analysis and public information. The results suggest that the thematic management / public administration and aging are not being developed directly as both magazines surveyed in the research groups of federal universities. It was decided, therefore, to present a characterization of what both study objects present on the topic aging. Accordingly, it was found that the aging subject is being exploited in different areas of knowledge in an interdisciplinary approach. It was observed that most groups (n = 180) are concentrated in the area of health sciences, with predominant area of medicine (n = 39). As for scientific journals, it was observed that interdisciplinary journals with qualis A2 has a higher number of publications on human aging (n = 262). In this study, further reflection on population aging in the context of public administration studies have concluded that it is necessary, and also points to the need for more studies on aging and public administration.

Masonry is known as a building structure for thousands of years. Cases where masonry elements (several units laided together bonded or not with mortar and grouting) support the building structure are widely found. Until mid-19th century, almost all structures had masonry part of its structural elements, although not all historic construction can be called structural masonry the way we understand it today with high strength blocks. The great expansion on the use of structural masonry occurred after the development of specific techniques and equipment. Moreover, technological development has enabled the production of higher strength blocks, dimensional precision and uniformity. To certify the design specified quality, there is the need of construction technologic control. This is the guarantee of minimum structural performance. Quality control is necessary to receive (or acceptance) the materials and components, including blocks, concrete, grout and the mortar, and finally the acceptance of masonry. This paper presents an assessment of the masonry quality control. Two parts has focus in different topics. In the first, field study cases in São Carlos city are assessed. The cases include concrete and ceramic blocks masonry building, and the quality control plan of each case were checked. The other part, focus on evaluating the several quality control tests on prisms compressive strength. From an extensive database, simulations concerning on the calculation of the characteristic value and coefficients of variation of samples, are assessed and weighted. As a conclusion, we can point that the quality control as required by Brazilian standards are not always followed in practice. About the prism test, we suggest considering to evaluate standard sample size specified today. It may be possible to reduce the number of specimens in each sample.

Roadkill and isolation of populations due to the barrier effect can be considered the main direct impacts of roads on wildlife. Mammals by behavioral, size and charisma features are one of the groups of vertebrates that require mitigation for mortality, as they are also among the most seriously injured on roads. An important approach to effectively mitigate roadkill on highways is to locate the points where roadkill are concentrated. The objective of this study was to evaluate the variation in mortality of mammals due to the duplication of the BR 101 highway south. In addition to the K Ripley aggregation analysis, were generated habitat suitability models (MAH) to identify favorable locations roadkill species, using the model functional groups for prediction of highway stretches with more chances to roadkill. It was recorded 21 taxa of mammals get hit, being the most abundant gender Didelphis (n = 721), followed by Cerdocyon thous (n = 108). The abundance of carcasses decreases between before and after the duplication (F 18.04 p = <0.001). Hotspots were not overlapped between the periods analyzed, indicating that some explanatory factor has changed over the work. Observing the variables that contributed most to the models for each functional group, we noted that there were differences in the most influential variables for each functional group in different periods. Of the nine generated models, we note that six variables contributed more than 20% in different models. There were differences between the periods before, during and after the duplication of the variables that contributed most or contribution value in functional groups. These differences may reflect the change in the distribution of roadkill among highway doubling periods. Both approaches demonstrated that there have been changes in the magnitude and distribution of roadkill in the period prior to the period after duplication. So a highway with two paviments differ from a highway with four paviments about how the mammals react in terms of movement and relationship to landscape.

Pilosocereus aureispinus (Buining & Brederoo) F. Ritter is a narrow endemic columnar cactus of eastern Brazil, occurring at Ibotirama and Oliveira dos Brejinhos, Bahia. In this work the genetic diversity and population structure were assessed for eight microsatellite loci in four P. aureispinus localities of occurrence, covering its known distribution. Genetic diversity levels were relatively high (A = 4,2 e HE = 0,451) comparing with closely related species and other narrowly distributed plant species. Significant Hardy-Weinberg Equilibrium departures and linkage disequilibrium were not detected. Private alleles in low frequencies and low levels of genetic structure (FST =0,071 e G”ST = 0,132) were detected. STRUCTURE software analysis did not identified structure, showing that samples from four analyzed localities represent a unique genetic group (K=1). These results pointed to high level of ongoing gene flow among sampled localities, which may counteract differentiation effects and genetic diversity loss. Despite P. aureispinus is not suffering genetic variability erosion due its narrow distribution, the species should be classified as endangered (EN) at IUCN Red List of Threatened Species due existent anthropogenic disturbs in regions where it occurs.

During the most recent decades the Brazilian foreign trade has shown significant changes regarding its pattern of trade specialization. These changes suggest that the country is undergoing into a process of exports reprimarization, caused mainly by the increase of the Chinese demand for commodities. The increase of the share of commodities in trade transactions between Brazil and the rest of the world has happened at the same time that manufactures have lost importance in the nations’ total trade. The new composition of the Brazilian foreign trade transactions indicates the country is following a new pattern in the international market. In addition, not only the country’s exports composition has changed over the last years, but we can also verify changes in the main exports destinations rank list. In this paper, our goal is to investigate the dynamics of changes in the Brazilian foreign trade transactions, focusing on exports, during the period of 1997 and 2003. We divided our analysis in different sectors, destination markets, and different periods to have a better understand of how changes happened. Our main hypothesis is that the reveled comparative advantages in international trade have led the country to the reprimarization process of its exports. Moreover, fewer sectors have shown high competitive levels over the last years, indicating a poor dynamics of Brazilian exports. In order to test our hypothesis, we first calculated revealed symmetric comparative advantages indexes, and then used Markov chains to calculate their probability distributions in different periods. We combined the two methodologies to identify the sectors and groups of technology where the country has higher competitiveness. We could also test for changes in exports composition, identifying which were the sectors and technology groups with higher trade competitiveness, in each period. Our results show that Brazil has been using its comparative advantages in the international trade, and its exports are becoming more dependent of commodities, since this is the group of products with higher revealed comparative advantages index. We also found a general loss of competitiveness in the non-commodity sectors during the analyzed period, which clearly shows that the country is facing a process of export reprimarization. The analysis of trade regarding different groups of countries shows that, even though with different intensities, commodity exports are becoming more relevant to all exports destinations (BRICS, European Union, MERCOSUL, and NAFTA), and it has happened more intensively during the third reporting period (2007- 2011). In addition, we also found that there is an indication that, in the future (ceteris paribus), there will be a possible convergence of exports in sectors with lower levels of comparative advantage. Our findings indicate that Brazil has been losing competitiveness in international trade, even with those products that the country has more comparative advantages in trade.

Increasing urbanization has impacted in various ways in the environment, such as changes in the hydrological cycle, increased flooding and pollution of rain origin. Soil sealing and removal of vegetation reduce infiltration and increase the volume and speed of runoff. With the questioning of the hygienists paradigms based on rapid evacuation of runoff, alternative drainage systems seek temporal rearrangement of the flow from the use of Best Management Practices and forms of rainwater management integrated with urbanization. Some Brazilian cities have public policies to encourage the deployment of alternative drainage systems, as is the case of Ribeirão Preto, a city in the state of São Paulo with a long history of problems related to the management of storm water, as floods and maintenance its source to the underground water consumption. With the inclusion of flow control requirements in the legislation, multiplied by the city storm control structures. The objective of this study is to analyze the implementation of these BMPs in urban subdivisions, from the point of view of the ownership and use of these spaces and their integration with the surroundings. From the survey of legislation and storm control structures performed in the city, were selected two installments, the Allotment Parque dos Servidores and the Condominium Quinta do Golfe, for characterization and analysis of the conditions of pre-occupation, urban design and drainage and finally, the space for BMPs. The results highlights the neglect of the management of these spaces where maintenance is precarious and the interference of the population could compromise its hydrological functions. We conclude therefore that the technical implementation of compensatory policy is an ongoing process, not just boils down to its implementation, its success is linked to urban-landscape qualification, frequent maintenance, as well as community education and involvement in the management of these spaces

The actual agricultural production system requires the use of chemicals such as pesticides and antimicrobials. These compounds, when reach aquatic environments, can cause serious environmental problems and affect target and non-target organisms such as microorganisms, that play key ecological functions to the ecosystem functioning. So, the objectives of this study were: (i) to evaluate the bactericidal action of oxytetracycline (OTC) and fungicide imazalil (IMZ) on bacterial ecological function of pesticide fipronil degradation; (II) evaluate the effect of oxytetracycline on density and aquatic bacterial diversity; (III) to monitor changes in bacterial dynamics in the presence of fipronil. Water was sampled in Beija-Flor Reservoir for mounting the experiments. Microcosms were prepared in triplicates for six different treatments: water; water and OTC; water and IMZ; water and fipronil; water, fipronil and OTC; water, fipronil and IMZ. The microcosms were kept in the dark at 21oC. Samples were collected at 1, 5, 10, 20, 45 and 70 days of incubation. It was determined the water pH, the dissolved organic carbon (DOC), total nitrogen (TN), OTC and fipronil concentrations. Water samples from the microcosms were also used for bacterial density analysis by epifluorescence microscopy and diversity by DGGE band profiles analysis. The presence of OTC alone and especially mixed with IMZ affects bacterial diversity, but does not cause significant effect on fipronil degradation, suggesting the existence of functional redundancy among the individuals that formed the bacterial community. The oxytetracycline, at certain concentrations, promotes a bacterial density decrease and diversity increase, probably by mediating the coexistence of species as a result of the growth control of the best competitive bacteria. Fipronil may cause bacterial density increase but, concerning its diversity, initially in the experiment, it was reduced, comparing with the control samples. However, after 70 days, the diversity was similar, suggesting that the community was reestablished, leading us to consider that the community was resilient to the impact caused by fipronil.

The study of juvenile offender’s interactions with mother, brother, and friend indicates which categories of social skills (assertiveness, self-control, conversation, and empathy) are established by shaping and modeling processes. Furthermore, it produces more evidences to the relationship between prosocial and antisocial behavior. This study aimed to describe a set of interlocking behavioral contingencies (IBCs) comprised by categories of social skills, which in turn contribute to legal measures outcomes. This study is made up by three independent chapters. The chapter 1. “Social skills of young offenders and at risk adolescents” discussed the social skills repertories as one of multiple factors of evaluation and intervention with adolescents. In summary, the outcomes indicated improvement on social skills categories, specially presented in home settings, the decrease of offending persistence, and lower evidences of the impact of social skills improvements on other adults and peers relationships. The chapter 2, named “Contributions of conceptual, descriptive and experimental metacontingencies studies to family interactions”, explored the metacontingency unit of analysis. Specifically, it discussed the interpersonal relationship patterns as behavioral products transmitted along family members. The last chapter, named “Identifying social skills repertoires in juvenile offenders´ interactions with relatives and friends: a metacontingencies analysis” aimed to describe IBCs that contribute to legal measures results. The participants were three families composed by a mother, a juvenile offender, and a brother without a history of delinquency. Self-reports instruments and interviews were used. The data analysis procedures were as follows: the development of IBCs coding system, establishing relationship between categories of IBCs and categories of social skills, and establishing relationship between categories of IBCs and categories of aggregate products. The results suggested that the participants, who achieved better scores on socials skills categories, also got engaged in conversation, support, negotiation, cooperation, and rules establishment interactions. Also they achieved some of the goals of legal measures (aggregate products).

The advent and popularization of the Internet has enabled the cultural convergence movement, creating numerous online communities as well as the consolidation of collective intelligence. Without being blocked by geographical barriers that once separated them, fans of today are much more active, organized and eager for content. Their voices can now be heard by the companies holding the canonicity of the stories on the internet, through protests on social networks and unofficial content building (fandom culture). Their reactions can influence and even change the original plots. This work aimed to study this phenomenon from the fans perspective and their participation in the evolution of the transmedia universe of Mass Effect games (2007-2012), from Bioware, through its unofficial productions such as fanfiction, specific actions through crowdfunding platforms and interactions via social networking communities like Facebook, in response to the end of game trilogy, which generated great dissatisfaction due to an expectation not fulfilled (from the perspective of those fans). It analyzed the narrative complexity of the work, and how this aspect influenced the relationship with the fans, culminating in this highly organized protest action against the ending, forcing the company holding the canon content to retract and change the ending of its work.
