Structured business solution for infrastructure projects

Companies seeking to continue growing and developing need to consider the possibility of international expansion and what that represents to their future. To tackle this challenge it becomes necessary to establish the company’s interests and priorities as well as defining and assessing the foreign market opportunities of a specific industry. This directed research internship proposes and conducts a simulation of the preliminary foreign market assessment and selection within the Juncker Plan: country filtering and ranking having as a frame of reference the second largest construction company in Brazil, Andrade Gutierrez.

Pattern operators for grid

The definition and programming of distributed applications has become a major research issue due to the increasing availability of (large scale) distributed platforms and the requirements posed by the economical globalization. However, such a task requires a huge effort due to the complexity of the distributed environments: large amount of users may communicate and share information across different authority domains; moreover, the “execution environment” or “computations” are dynamic since the number of users and the computational infrastructure change in time. Grid environments, in particular, promise to be an answer to deal with such complexity, by providing high performance execution support to large amount of users, and resource sharing across different organizations. Nevertheless, programming in Grid environments is still a difficult task. There is a lack of high level programming paradigms and support tools that may guide the application developer and allow reusability of state-of-the-art solutions. Specifically, the main goal of the work presented in this thesis is to contribute to the simplification of the development cycle of applications for Grid environments by bringing structure and flexibility to three stages of that cycle through a commonmodel. The stages are: the design phase, the execution phase, and the reconfiguration phase. The common model is based on the manipulation of patterns through pattern operators, and the division of both patterns and operators into two categories, namely structural and behavioural. Moreover, both structural and behavioural patterns are first class entities at each of the aforesaid stages. At the design phase, patterns can be manipulated like other first class entities such as components. This allows a more structured way to build applications by reusing and composing state-of-the-art patterns. At the execution phase, patterns are units of execution control: it is possible, for example, to start or stop and to resume the execution of a pattern as a single entity. At the reconfiguration phase, patterns can also be manipulated as single entities with the additional advantage that it is possible to perform a structural reconfiguration while keeping some of the behavioural constraints, and vice-versa. For example, it is possible to replace a behavioural pattern, which was applied to some structural pattern, with another behavioural pattern. In this thesis, besides the proposal of the methodology for distributed application development, as sketched above, a definition of a relevant set of pattern operators was made. The methodology and the expressivity of the pattern operators were assessed through the development of several representative distributed applications. To support this validation, a prototype was designed and implemented, encompassing some relevant patterns and a significant part of the patterns operators defined. This prototype was based in the Triana environment; Triana supports the development and deployment of distributed applications in the Grid through a dataflow-based programming model. Additionally, this thesis also presents the analysis of a mapping of some operators for execution control onto the Distributed Resource Management Application API (DRMAA). This assessment confirmed the suitability of the proposed model, as well as the generality and flexibility of the defined pattern operators

Working in IT projects – Options and Limits of Work Design

Flexible forms of work like project work are gaining importance in industry and services. Looking at the research on project work, the vast majority of present literature is on project management, but increasingly, problems concerning the quality of work and the efficiency of project teams become visible. The question now is how project work can be structured in order to simultaneously provide efficient and flexible work and healthy working conditions ensuring the development of human resources for a long time. Selected results of publicly funded research into project work will be presented based on case studies in 7 software development /IT consulting project teams (N=34). A set of different methods was applied: interviews with management/project managers, group interviews on work constraints, a monthly diary about well-being and critical incidences in the course of the project, and a final evaluation questionnaire on project outcomes focusing on economic and health aspects. Findings reveal that different types of projects exist with varying degree of team members’ autonomy and influence on work structuring. An effect of self-regulation on mental strain could not be found. The results emphasize, that contradicting requirements and insufficient organizational resources with respect to the work requirements lead to an increased work intensity or work obstruction. These contradicting requirements are identified as main drivers for generating stress. Finally, employees with high values on stress for more than 2 months have significantly higher exhaustion rates than those with only one month peaks. Structuring project work and taking into account the dynamics of project work, there is a need for an active role of the project team in contract negotiation or the detailed definition of work – this is not only a question of individual autonomy but of negotiation the range of option for work structuring. Therefore, along with the sequential definition of the (software) product, the working conditions need to be re-defined.

Educação alimentar infantil: potencialidades de estudantes de educação de infância

Resumo: Na promoção de comportamentos alimentares saudáveis ao longo da vida. que deve iniciar-se o mais precocemente possível, a educação alimentar é um elemento chave. O jardim-de-infância é um espaço efectivo na implementação de projectos de educação alimentar, onde os educadores de infância são actores imprescindíveis. Este estudo teve como objectivo desenvolver uma metodologia apropriada para identificar as capacidades de estudantes de educação de infância e avaliar as suas aptidões no contexto da educação alimentar infantil. A população alvo do estudo foram estudantes do 4ºano da licenciatura em educação de infância de instituições públicas e privadas da área metropolitana de Lisboa (n=287). Construiu-se um videograma, integrador dos domínios da aprendizagem (cognitivo e afectivo) e dos factores associados aos comportamentos em saúde (predisponentes, capacitadores e de esforço). A construção dos questionários estruturou-se em: conhecimentos-atitudes-comportamentos.Pretendia-se que os estudantes transmitissem a sua opinião, de acordo com os questionários.Os estudantes manifestaram conhecimentos, no âmbito da alimentação infantil e da utilidade e aplicabilidade da educação alimentar.Nenhum estudante apresentou conhecimentos negativos, numa escala de zero a 18 valores, 86,9% obtiveram uma classificação entre 11 e 17 valores e 13,1% a classificação máxima.A atitude dos estudantes revelou-se consensual com o desejável, 98,5% apresentaram atitudes positivas face aos aspectos estruturadores das actividades de educação alimentar.No domínio do "saber fazer" 51,0% dos estudantes demonstraram fragilidades no seu desempenho/comportamento. Em conclusão, a utilização do questionário demonstrou ser apropriado para a medição dos conhecimentos, das atitudes e como forma de os estudantes, após visionarem o videograma, espelharem o seu desempenho/comportamento face à representação do educador de infância. A taxa de resposta nunca foi inferior a 98,9% (n=284). No domínio dos conhecimentos, os estudantes manifestaram concepções positivas no campo da alimentação infantil e da educação alimentar. As atitudes enfatizaram-se no domínio afectivo, nos aspectos relacionais e comunicacionais. No domínio dos comportamentos, 91,8% dos estudantes apresentaram dificuldades na identificação dos aspectos menos correctos do desempenho dos actores do video, o que pode sugerir lacunas no âmbito do "saber fazer". Abstract:Nutrition education is key element to promote lifelong healthy eating behaviours and it must begin since early stages of life. Nursery schools are an effective space in the implementation of nutrition education projects, where the nursery teachers are indispensable actors. The aim of this study was to develop an appropriate methodology to identify nursery education student´s skills and evaluate their attitudes in the childhood nutrition education's context. The study's population were students of the 4th degree in private and public nursery education universities in Lisbon metropolitan area (n=287). A video integrator of learning domains (cognitive and affective) and of factors associated with health behaviours (predisposing, enabling and reinforcing) was developed. Questionnaire´s construction was structured in: knowledge-attitudes-behaviours.According to the questionnaires students were asked to transmit their opinion. Students revealed knowledge, in the scope of the childhood nutrition and in utility and applicability of nutrition education. No students presented negative results in knowledge ina zero - 18 scale; 86,9% students obtained a classification between 11 and 17 and the maximum classification was obtained by 13.1% students. Student's attitude was according to win the desirable, 98,5% student´s revealed positive attitudes in the nutrition education's structure aspects of chilhood activities.In the domain of the "know to do" 51,0% of students showed fragilities in their performance/behaviour. In conclusion, the questionnaire´s utilization confirm to be appropriated in measurement knowledge and attitudes and also, after watching the video, as a way for students reflect their performance/behaviour face to the nursery teacher´s representation. Answer´s rate was never lower than 98.9% (n=284). In the knowledge's domain students demonstrated positive conceptions in the childhood nutrition and nutrition education's fields. Attitudes were emphasized in the effective domain in the communication and relational aspects. In behaviour's domain 91.8% students presented difficulties in identifying the less correct aspects of the video actor's performance what may suggest gaps in the "know to do" scope.
