Software engineering researchers are challenged to provide increasingly more powerful levels of abstractions to address the rising complexity inherent in software solutions. One new development paradigm that places models as abstraction at the forefront of the development process is Model-Driven Software Development (MDSD). MDSD considers models as first class artifacts, extending the capability for engineers to use concepts from the problem domain of discourse to specify apropos solutions. A key component in MDSD is domain-specific modeling languages (DSMLs) which are languages with focused expressiveness, targeting a specific taxonomy of problems. The de facto approach used is to first transform DSML models to an intermediate artifact in a HLL e.g., Java or C++, then execute that resulting code.^ Our research group has developed a class of DSMLs, referred to as interpreted DSMLs (i-DSMLs), where models are directly interpreted by a specialized execution engine with semantics based on model changes at runtime. This execution engine uses a layered architecture and is referred to as a domain-specific virtual machine (DSVM). As the domain-specific model being executed descends the layers of the DSVM the semantic gap between the user-defined model and the services being provided by the underlying infrastructure is closed. The focus of this research is the synthesis engine, the layer in the DSVM which transforms i-DSML models into executable scripts for the next lower layer to process.^ The appeal of an i-DSML is constrained as it possesses unique semantics contained within the DSVM. Existing DSVMs for i-DSMLs exhibit tight coupling between the implicit model of execution and the semantics of the domain, making it difficult to develop DSVMs for new i-DSMLs without a significant investment in resources.^ At the onset of this research only one i-DSML had been created for the user- centric communication domain using the aforementioned approach. This i-DSML is the Communication Modeling Language (CML) and its DSVM is the Communication Virtual machine (CVM). A major problem with the CVM's synthesis engine is that the domain-specific knowledge (DSK) and the model of execution (MoE) are tightly interwoven consequently subsequent DSVMs would need to be developed from inception with no reuse of expertise.^ This dissertation investigates how to decouple the DSK from the MoE and subsequently producing a generic model of execution (GMoE) from the remaining application logic. This GMoE can be reused to instantiate synthesis engines for DSVMs in other domains. The generalized approach to developing the model synthesis component of i-DSML interpreters utilizes a reusable framework loosely coupled to DSK as swappable framework extensions.^ This approach involves first creating an i-DSML and its DSVM for a second do- main, demand-side smartgrid, or microgrid energy management, and designing the synthesis engine so that the DSK and MoE are easily decoupled. To validate the utility of the approach, the SEs are instantiated using the GMoE and DSKs of the two aforementioned domains and an empirical study to support our claim of reduced developmental effort is performed.^

In recent years, a surprising new phenomenon has emerged in which globally-distributed online communities collaborate to create useful and sophisticated computer software. These open source software groups are comprised of generally unaffiliated individuals and organizations who work in a seemingly chaotic fashion and who participate on a voluntary basis without direct financial incentive. The purpose of this research is to investigate the relationship between the social network structure of these intriguing groups and their level of output and activity, where social network structure is defined as 1) closure or connectedness within the group, 2) bridging ties which extend outside of the group, and 3) leader centrality within the group. Based on well-tested theories of social capital and centrality in teams, propositions were formulated which suggest that social network structures associated with successful open source software project communities will exhibit high levels of bridging and moderate levels of closure and leader centrality. The research setting was the SourceForge hosting organization and a study population of 143 project communities was identified. Independent variables included measures of closure and leader centrality defined over conversational ties, along with measures of bridging defined over membership ties. Dependent variables included source code commits and software releases for community output, and software downloads and project site page views for community activity. A cross-sectional study design was used and archival data were extracted and aggregated for the two-year period following the first release of project software. The resulting compiled variables were analyzed using multiple linear and quadratic regressions, controlling for group size and conversational volume. Contrary to theory-based expectations, the surprising results showed that successful project groups exhibited low levels of closure and that the levels of bridging and leader centrality were not important factors of success. These findings suggest that the creation and use of open source software may represent a fundamentally new socio-technical development process which disrupts the team paradigm and which triggers the need for building new theories of collaborative development. These new theories could point towards the broader application of open source methods for the creation of knowledge-based products other than software.

The purpose of this qualitative study was to gain an understanding of what participation in a first year residential learning community meant to students 2-3 years after their involvement in the program. Various theories including environmental, student involvement, psychosocial and intellectual, were used as a framework for this case study. Each of the ten participants was a junior or senior level student at the time of the study, but had previously participated in a first year residential learning community at Florida International University. The researcher held two semi-structured interviews with each participant, and collected data sheets from each. The narrative data produced from the interviews were transcribed, coded and analyzed to gain insights into the experiences and perspectives of the participants. Member checking was used after the interview process. A peer reviewer offered feedback during the data analysis. The resulting data was coded into categories, with a final selection of four themes and 15 sub-themes, which captured the essence of the participants' experiences. The four major themes included: (a) community, (b) involvement, (c) identity, and (d) academics. The community theme is used to describe how students perceived the environment to be. The involvement theme is used to describe the students' participation in campus life and their interaction with other members of the university community. The identity theme is used to describe the students' process of development, and the personal growth they underwent as a result of their experiences. The academics theme refers to the intellectual development of students and their interaction around academic issues. The results of this study showed that the participants valued greatly their involvement in the First Year Residents Succeeding Together program (FYRST) and can articulate how it helped them succeed as students. In describing their experience, they most recall the sense of community that existed, the personal growth they experienced, the academic development process they went through, and their involvement, both with other people and with activities in their community. Recommendations are provided for practice and research, including several related to enhancing the academic culture, integrating faculty, utilizing peer influence and providing further opportunities to create a seamless learning environment.

The citizenship is a fundamental category to the democratic progress and the development and concretization of human rights, in addition to being one of the essential foundations of democratic contextualized in the rule of law of the Federative Republic of Brazil. That’s exactly why the discussion about its concept and content is a paramount requirement to the understanding and interpretation-application-concretization of the Federal Constitution of 1988, as well as its democracy, since there is no democracy without citizenship. That is why the general objective of the research is to determine the characteristics of the citizenship, relating it to the Law, as well as to discuss (critically) its inclusion in the list of fundamental rights and delimitate the scope of protection and the limits of this right, in the context of Brazilian law post-1988 Constitution. The specific objectives are: a) to analyze the concept of citizenship, its extent and scope, contextualizing it historically; b) to examine the evolution of the legal and regulatory treatment of the citizenship in Brazilian constitutions, focusing on the 1988 Constitution; c) assess whether citizenship can be considered a fundamental right; d) to investigate which implications, theoretical and practical, of assignment fundamentality character to the right to citizenship. This research identifies and deconstructs current conceptual confusions, such as the lack of distinction between citizenship and nationality; citizenship and electoral capacity; citizenship and person. It also helps to identify and oppose the generalizations, as well as the excessively abstract associations which tend to purely metaphysical understandings, fluid and empty of any content. The main virtue, however, is the proposed of understanding of the citizenship as a fundamental right and the examination of the relationship between citizenship and human dignity. In this context, citizenship appears as a corollary of human dignity and it goes beyond. This (human dignity) requires equality, non-arbitraries, non-excessive, disproportionate or unreasonable impositions affecting their freedom rights, and, yet, doesn’t affect a minimum core of possibilities of have to a decent life, in conditions of freedom and self-conformation involved in the necessary consideration of the individual as a subject. All of this requires a decision-making process, molded by the citizenship, which reaches the entire development process of possible state interventions, to ensure the person as a subject, the right holder and the objective point of reference of the juridical relations. Thus, the citizenship represents a substantial and beneficial addition to the human dignity, since the emancipated citizen is a person, formally and materially, qualified, to be able to build their own and collectively organized history, to participate effectively in the making processes decision juridical and social

Wireless Sensor and Actuator Networks (WSAN) are a key component in Ubiquitous Computing Systems and have many applications in different knowledge domains. Programming for such networks is very hard and requires developers to know the available sensor platforms specificities, increasing the learning curve for developing WSAN applications. In this work, an MDA (Model-Driven Architecture) approach for WSAN applications development called ArchWiSeN is proposed. The goal of such approach is to facilitate the development task by providing: (i) A WSAN domain-specific language, (ii) a methodology for WSAN application development; and (iii) an MDA infrastructure composed of several software artifacts (PIM, PSMs and transformations). ArchWiSeN allows the direct contribution of domain experts in the WSAN application development without the need of specialized knowledge on WSAN platforms and, at the same time, allows network experts to manage the application requirements without the need for specific knowledge of the application domain. Furthermore, this approach also aims to enable developers to express and validate functional and non-functional requirements of the application, incorporate services offered by WSAN middleware platforms and promote reuse of the developed software artifacts. In this sense, this Thesis proposes an approach that includes all WSAN development stages for current and emerging scenarios through the proposed MDA infrastructure. An evaluation of the proposal was performed by: (i) a proof of concept encompassing three different scenarios performed with the usage of the MDA infrastructure to describe the WSAN development process using the application engineering process, (ii) a controlled experiment to assess the use of the proposed approach compared to traditional method of WSAN application development, (iii) the analysis of ArchWiSeN support of middleware services to ensure that WSAN applications using such services can achieve their requirements ; and (iv) systematic analysis of ArchWiSeN in terms of desired characteristics for MDA tool when compared with other existing MDA tools for WSAN.

This study aimed to build a virtual learning environment for application of the nursing process based on the NANDA-I, NOC, NIC and ICNP® . Faced with problems related to learning of the nursing process and classifications, there is an urgent need to develop innovative teaching resources that modify the relationship between students and teachers. The methodology was based on the steps inception, development, construction and transition, and the software development process Rational Process Unifield. The team involved in the development of this environment was composed by researchers and students of The Care and Epidemiological Practice in Health and Nursing and Group of the Software Engineering curse of the Federal University Rio Grande do Norte, with the participation of the Lisbon and Porto Schools of Nursing, in Portugal. In the inception stage the inter research communication was in order to define the functions, features and tools for the construction process. In the preparation, step the planning and modeling occurred, which resulted in the creation of a diagram and a architectural drawings that specify the features and functionality of the software. The development, unit testing and integrated in interfaces of the modules and areas (administrator, teacher, student, and construction of the NP). Then the transition step was performed, which showed complete and functioning system, as well as the training and use by researchers with its use in practice. In conclusion, this study allowed for the planning and the construction of an educational technology, and it is expected that its implementation will trigger a substantial change in the learning of the nursing process and classifications, with the student being active agent of the learning process. Later, an assessment will be made of functional performance, which will enable the software development, with a feedback, correction of defects and necessary changes. It is believed that the software increment after the reviews, this tool grow further and help insert this methodology and every language under the educational and health institutions, promoting paradigmatic desired change by nursing.

This research aimed to analyze the main government efforts to promote economic development in the Northeast, from 1985 to 2010, under the view that growth is crucial for increasing industrialization process and allows for more significant growth patterns. The analysis was the context in which state governments react to the abandonment of developmental line the federal level, in the 1980s, incorporating features of the actions called endogenous regional development and providing local players with greater responsibility in the development process. Justifies the need to analyze the following scenario: state governments in northeastern Brazil using relevant part of its resources to finance the installation and expansion of companies through tax incentives, with a view to generating income and employment, whilst waiting for an increase in output and a positive change in economic dynamism. In addition, it puts in question the fact that these policies receive such importance of state administrations for the purpose of achieving regional development. It was left to consider, therefore, the contents of the shares elected by state governments to examine the scope of these policies both in the pattern of growth, the transformation of the industrial sector and the development of the region attention to changes in state production structures. Due to limitations on the availability of data and time to carry out research, we were elected three states for the study: Rio Grande do Norte, Ceará and Maranhão. The study found that, despite the contribution of policies analyzed to economic growth, sub-national states are unable to compensate for the lack of development agencies structured at the federal level.

This study has the main objective to analyze the role of the bodies of state and local governance of tourism, aimed at tourism development process in the city of Manaus / AM , by the public practices of planning, management and development activity in the respective municipality . To the specific objectives were established four aims: 1) To characterize the process of formation of governance entities active in tourism in the city of Manaus. 2) Lift the actions planned and executed by the authorities aimed at cultural tourism in the period 2003-2014. 3) To question through the perception of the actors representing the different classes and entities of the Amazonian society, the actions planned and executed by the authorities aimed at cultural tourism in the period 2003-2014 and 4) Identify key similarities and the differences in decision-making about actions aimed at cultural tourism in Manaus. We adopted a qualitative approach, using the methodological design of descriptive and exploratory, with the help of the use of the techniques of literature search, document, with on-site data collection through interviews with semi-structured script application forms to the representatives of sectorial institutions that make up the locations of governance in tourism. In addition, the treatment of information was used content analysis technique. In response to stated objectives, it can be concluded that the creation of public arenas, through the tourism of governance has enabled incipient discussion in a democratic manner and decision-making in the area of planning and management of tourism in Manaus. It was also observed that obstacles that hinder and undermine the structures of the bodies, which reflect the joint, in the promotion and cultural tourism development in the city of Manaus.

The Virtual Reality techniques applied in Electricity Environments provide a new supervisory control paradigm. The fact of existing a virtual environment (VE), geometrically similar to a real substation, reduces the difference of mental models built by field operators compared with those built by system center operation improving the communication. Beside this, those systems can be used as visualization interfaces for electricity system simulators, training systems for professors and undergraduate students, field operators and maintenance professionals. However, the development process of these systems is quite complex, combining several activities such as implementation, 3D modeling, virtual sceneries construction, usability assessment and management project techniques. In this context, this work present a GUI strategy to build field arrangements based on scene graphs, to reduce time in Virtual Electricity Substations Arrangement development. Through this, mistakes during the VE building can be avoided making this process more reliable. As an concept proof, all toolkits developed in this work were applied in the virtualization of the substations from a Brazilian power concessionary named CEMIG.

This paper discusses the difficulties involved in managing knowledge-intensive, multinational, multiorganisational, and multifunctional project networks. The study is based on a 2-year quasi-ethnography of one such network engaged in the design and development of a complex new process control system for an existing pharmaceutical plant in Ireland. The case describes how, drawing upon the organisational heritage of the corporations involved and the logic implicit within their global partnership arrangements, the project was initially structured in an aspatial manner that underestimated the complexity of the development process and the social relations required to support it. Following dissatisfaction with initial progress, a number of critical management interventions were made, which appeared to contribute to a recasting of the network ontology that facilitated the cultivation and protection of more appropriate communicative spaces. The case emphasises the need to move away from rationalistic assumptions about communication processes within projects of this nature, towards a richer conceptualisation of such enterprises as involving collective sensemaking activities within and between situated ‘communities’ of actors. Contrary to much contemporary writing, the paper argues that space and location are of crucial importance to our understanding of network forms of organising.

This research has explored the relationship between system test complexity and tacit knowledge. It is proposed as part of this thesis, that the process of system testing (comprising of test planning, test development, test execution, test fault analysis, test measurement, and case management), is directly affected by both complexity associated with the system under test, and also by other sources of complexity, independent of the system under test, but related to the wider process of system testing. While a certain amount of knowledge related to the system under test is inherent, tacit in nature, and therefore difficult to make explicit, it has been found that a significant amount of knowledge relating to these other sources of complexity, can indeed be made explicit. While the importance of explicit knowledge has been reinforced by this research, there has been a lack of evidence to suggest that the availability of tacit knowledge to a test team is of any less importance to the process of system testing, when operating in a traditional software development environment. The sentiment was commonly expressed by participants, that even though a considerable amount of explicit knowledge relating to the system is freely available, that a good deal of knowledge relating to the system under test, which is demanded for effective system testing, is actually tacit in nature (approximately 60% of participants operating in a traditional development environment, and 60% of participants operating in an agile development environment, expressed similar sentiments). To cater for the availability of tacit knowledge relating to the system under test, and indeed, both explicit and tacit knowledge required by system testing in general, an appropriate knowledge management structure needs to be in place. This would appear to be required, irrespective of the employed development methodology.
