COMPASS is an experiment at CERN’s SPS whose goal is to study hadron structure and spectroscopy. The experiment includes a wide acceptance RICH detector, operating since 2001 and subject to a major upgrade of the central region of its photodetectors in 2006. The remaining 75% of the photodetection area are still using MWPCs from the original design, who suffer from limitations in gain due to aging of the photocathodes from ion bombardment and due to ion-induced instabilities. Besides the mentioned limitations, the increased luminosity conditions expected for the upcoming years of the experiment make an upgrade to the remaining detectors pertinent. This upgrade should be accomplished in 2016, using hybrid detectors composed of ThGEMs and MICROMEGAS. This work presents the study, development and characterization of gaseous photon detectors envisaging the foreseen upgrade, and the progress in production and evaluation techniques necessary to reach increasingly larger area detectors with the performances required. It includes reports on the studies performed under particle beam environment of such detectors. MPGD structures can also be used in a variety of other applications, of which nuclear medical imaging is a notorious example. This work includes, additionally, the initial steps in simulating, assembling and characterizing a prototype of a gaseous detector for application as a Compton Camera.

Numa época em que nos regemos, cada vez mais, pela Ciência e Tecnologia é fundamental que os cidadãos estejam devidamente informados, exercendo uma cidadania plena, tomando decisões fundamentadas e intervindo na sociedade. Para viabilizar estes intentos, é importante que a educação científica se inicie nas escolas o mais cedo possível, para a edificação de futuros cidadãos cientificamente literatos. Apesar das dificuldades manifestadas pelos professores na implementação do ensino das Ciências nas escolas do 1.º Ciclo do Ensino Básico (1.º CEB), são várias as potencialidades que têm vindo a ser atribuídas a este campo curricular. Com este estudo pretendeu-se descrever e interpretar as conceções de ensino e aprendizagem de professores do 1.º CEB, no contexto do Programa de Formação em Ensino Experimental das Ciências (PFEEC), bem como averiguar como implementam as atividades práticas de índole experimental e investigativo em sala de aula, e quais as dificuldades sentidas durante a sua realização. Para atingir estas finalidades, utilizou-se uma abordagem metodológica de orientação interpretativa, de base naturalista, recorrendo-se ao método de estudo de casos múltiplos, fazendo-se uso de distintos instrumentos de recolha de dados: observação naturalista, entrevistas, notas de campo e documentos escritos. Participaram neste estudo três professoras do 1.º CEB, pertencentes a duas escolas do concelho de Faro. Os resultados evidenciaram que a maioria das conceções das professoras relativamente às categorias edificadas foram modificadas após a frequência do PFEEC. Contudo, outras aparentam estar fortemente enraizadas. Estas mudanças que ocorreram parecem estar relacionadas com a modificação das ações, atitudes e sentimentos das professoras que se coadunaram com a metodologia de trabalho defendida pelo PFEEC, culminando na modificação das suas práticas letivas. Durante a planificação e implementação das atividades as professoras manifestaram algumas dificuldades e constrangimentos. Todavia, no decorrer do PFEEC, estes obstáculos foram sendo minimizados; IMPACT OF A TRAINING PROGRAMME ON THE CONCEPTIONS AND PRACTICES OF PRIMARY SCHOOL TEACHERS ABSTRACT: In an era in which we are governed, more and more, by Science and Technology, it is fundamental that citizens are properly informed; exercising full citizenship; making fundamental decisions and intervening in society. To enable these intentions, it is important that scientific education takes place in schools as soon as possible, so as to edify future scientifically literate citizens. Despite the teachers' difficulties in implementing Science teaching in Primary Schools, there are many potentialities that have come to be attributed to this curricular field. This study is intended to describe and interpret science learning and teaching conceptions of the Primary School teachers, in the context of the Training Programme in Experimental Science Teaching (PFEEC), as well as determine how they implement the experimental science and inquiry based learning activities in the classroom, and take into account what experienced difficulties occur during their execution. To reach these goals, a methodological approach of interpretive orientation, on a naturalistic basis, using a method of multiple case study, by means of distinct data collection tools was used: naturalistic observation, interviews, field research notes and written documents. Three Primary School teachers of the municipality of Faro took part in this study. The results showed that the majority of the teachers' conceptions in relation to the edified categories were modified after the attendance of the PFEEC. However, others seem to be deeply rooted. These changes that occurred seem to be related to the modification of actions, attitudes and feelings of the teachers who complied with the work methodology defended by the PFEEC, culminating in the modification of their session practices. During the planning and implementation of the activities, the teachers showed some difficulties and constraints. Nevertheless, during the PFEEC, these obstacles were minimized.

The objective of this study is to analyze the validity of working with proofs in the classroom and to present a partial list of proofs of mathematical formulae of the Brazilian secondary/high school curriculum. The adaptation of the proofs into the knowledge and abilities of a secondary school student should also be considered. How the teaching of proofs is treated in official publications in Brazil and other countries is also described. Working with proofs provides a number of benefits to the students, including: the development of logical reasoning, argumentative capacity, analytical skills on a daily basis, as well as motivation and a better understanding of mathematics as a science. The convenience of including the teaching of proofs in Brazilian secondary school curriculum and the need of a balance between the abstraction of proofs and contextualization of the school programmes is discussed. The approach of the proof teaching in the classroom can become a motivating factor or, conversely, a discouraging one. The conclusion is that it would be very useful to create a reference list covering the mathematical expressions of school programmes with their respective proofs that can be understood by secondary school students.

Objective: The purpose of this study was to develop and test psychometric properties of a Mealtime Interaction Clinical Observation Tool (MICOT) that could be used to facilitate assessment and behavioural intervention in childhood feeding difficulties. Methods: Thematic analysis of four focus groups with feeding and behaviour experts identified the content and structure of the MICOT. Following refinement, inter-rater reliability was tested between three healthcare professionals. Results: Six themes were identified for the MICOT, which utilises a traffic-light system to identify areas of strength and areas for intervention. Despite poor inter-rater reliability, for which a number of reasons are postulated, some correlation between psychologists’ ratings was evident. Healthcare professionals liked the tool and reported that it could have good clinical utility. Conclusion: The study provides a promising first version of a clinical observation tool that facilitates assessment and behavioural intervention in childhood feeding difficulties.

Background: Research suggests that forensic mental health services and staff can play an important role in the recognition and intervention with attachment-related behaviours to promote engagement and recovery. There is a lack of literature exploring whether the attachment needs of forensic service-users are recognised and, associations between attachment style and factors predictive of recovery. Aims: This study aimed to examine the extent to which service-users and keyworkers agree about service-users’ attachment and to identify whether attachment was associated with service attachment, working alliance, ward climate and recovery. Methods: Twenty-two service-users from low and medium secure forensic services, completed questionnaire measures of their attachment style, service attachment, working alliance, ward climate and experiences of recovery. Nineteen keyworkers completed measures of the service-users attachment style and working alliance. Results: There was strong agreement between service-users and staff for attachment anxiety (ICC=0.71) but poor agreement for attachment avoidance (ICC=0.39). Service attachment was associated with more positive perceptions of staff support (r=0.49) and avoidant attachment was associated with lower ratings of recovery (r=-0.51). Correlations between attachment style and service attachment, working alliance and ward climate were small and non-significant. Conclusions: A focus on staff training to support recognition of the nature and impact of avoidant attachment styles is indicated. The findings suggest that interventions to enhance staff - service-user relationships may be important for service attachment and indeed promotion of a recovery focused orientation amongst service-users high in avoidant attachment may improve wellbeing and outcomes.

Since the emergence of software engineering in the late 1960's as a response to the software crisis, researchers throughout the world are trying to give theoretical support to this discipline. Several points of view have to be reviewed in order to complete this task. In the middle 70's Frederick Brooks Jr. coined the term "silver bullet" suggesting the solution to several problems rela-ted to software engineering and, hence, we adopted such a metaphor as a symbol for this book. Methods, modeling, and teaching are the insights reviewed in this book. Some work related to these topies is presented by software engineering researchers, led by Ivar Jacobson, one of the most remarkable researchers in this area. We hope our work will contribute to advance in giving the theoretieal support that software engineering needs.
