Meta, tracer - MOF with traceability

The following document proposes a traceability solution for model-driven development. There as been already previous work done in this area, but so far there has not been yet any standardized way for exchanging traceability information, thus the goal of this project developed and documented here is not to automatize the traceability process but to provide an approach to achieve traceability that follows OMG standards, making traceability information exchangeable between tools that follow the same standards. As such, we propose a traceability meta-model as an extension of MetaObject Facility (MOF)1. Using MetaSketch2 modeling language workbench, we present a modeling language for traceability information. This traceability information then can be used for tool cooperation. Using Meta.Tracer (our tool developed for this thesis), we enable the users to establish traceability relationships between different traceability elements and offer a visualization for the traceability information. We then demonstrate the benefits of using a traceability tool on a software development life cycle using a case study. We finalize by commenting on the work developed.

Bullying: a violência entre adolescentes em contexto escolar: uma meta-análise

O bullying diz respeito a um tipo de violência exercida entre pares em contexto escolar, quando um aluno agride o outro de modo repetitivo, sem razão, causando-lhe danos intencionalmente, havendo uma desigualdade de poder entre eles. A realidade é que os jovens de hoje são os adultos de amanhã, logo os condutores da sociedade onde vivem e o fato de estarem envolvidos em bullying, deixa-nos muito preocupados em relação ao futuro. A presente dissertação tem como objetivo descrever de que forma o fenómeno bullying tem expressão na população adolescente, em contexto escolar. Metodologicamente, recorremos à meta-análise para integrar os resultados de estudos já realizados sobre o bullying e extrair novas conclusões. Os resultados sugerem: a existência de alunos adolescentes envolvidos em bullying, inclusivamente nas escolas da Região Autónoma da Madeira; os tipos de bullying sinalizados como existentes são: o verbal, o físico, o sexual, o psicológico, o social e, ainda, o cyberbullying; as agressões mais frequentes são as físicas e as verbais; as agressões ocorrem maioritariamente nos recreios, sala de aula, corredores e cantina; os diferentes perfis dos envolvidos; as diversas consequências para os intervenientes; os variados modos de intervenção em bullying.

Meta-theories in research: positivism, postmodernism, and critical realism

No scholar or researcher is able to provide robust evidence that counters the scant reflection on metatheory – mostly ontology and epistemology – underlying management studies in general, and industrial marketing and purchasing research in particular. This paper is a contribution to the indispensable discussion of metatheoretical alternatives in research, and most importantly, the strengths and shortcomings thereof, and respective implications on research questions, objectives, and findings.

WAMM: wiki aided meta modelling

All over the world, organizations are becoming more and more complex, and there’s a need to capture its complexity, so this is when the DEMO methodology (Design and Engineering Methodology for Organizations), created and developed by Jan L. G. Dietz, reaches its potential, which is to capture the structure of business processes in a coherent and consistent form of diagrams with their respective grammatical rules. The creation of WAMM (Wiki Aided Meta Modeling) platform was the main focus of this thesis, and had like principal precursor the idea to create a Meta-Editor that supports semantic data and uses MediaWiki. This prototype Meta-Editor uses MediaWiki as a receptor of data, and uses the ideas created in the Universal Enterprise Adaptive Object Model and the concept of Semantic Web, to create a platform that suits our needs, through Semantic MediaWiki, which helps the computer interconnect information and people in a more comprehensive, giving meaning to the content of the pages. The proposed Meta-Modeling platform allows the specification of the abstract syntax i.e., the grammar, and concrete syntax, e.g., symbols and connectors, of any language, as well as their model types and diagram types. We use the DEMO language as a proofof-concept and example. All such specifications are done in a coherent and formal way by the creation of semantic wiki pages and semantic properties connecting them.
