Embora de natureza radicalmente distinta, bullying e vinculação são fenómenos de natureza relacional. Se o bullying é descrito como um abuso sistemático de poder, que ocorre intencional e repetidamente entre pares, a vinculação refere-se ao estabelecimento de laços afectivos fortes com determinadas pessoas significativas, especialmente em momentos percepcionados como perigosos. A investigação, apesar do reduzido número de estudos, mostra uma relação entre estes conceitos. A agressão instrumental interpares parece estar relacionada com vinculações inseguras. O objectivo deste estudo é compreender a relação entre o bullying e os padrões de vinculação. Foi realizado em três escolas da zona de Évora, com os alunos do 7° ano (237 alunos). Utilizaram-se dois questionários de auto-relato: o QEVE - Questionário de Exclusão Social e Violência Escolar e o IVIA - Inventário sobre Vinculação para a Infância e a Adolescência. Os resultados deste estudo corroboram os estudos anteriores, relativamente aos comportamentos agressivos entre pares. Mostram que existem correlações estatisticamente significativas entre as dimensões da vitimação e da agressão e, ainda, verificou-se que a vinculação segura parece funcionar como um factor protector para a vitimação e a agressividade e a vinculação ansiosa parece relacionar-se com a vitimação. ABSTRACT: Although radically different, bullying and attachment are relational in nature phenomena. lf the bullying is described as a systematic abuse of power, which is intentionally and repeatedly between peers, attachment refers to the establishment of strong emotional ties with certain significant others, especially at times perceived as dangerous. The research, despite the small number of studies show a relationship between these concepts. Instrumental peer aggression seems to be associated with insecure attachments. The aim of this study is to understand the relationship between bullying and patterns of binding. lt was conducted in three schools in the district of Évora with the students of 7th Grade (237 students). We used two questionnaires self-report: the QEVE - Questionnaire of Social Exclusion and Violence in School and IVIA - lnventory on Attachment for Children and Adolescents. These results corroborate previous studies, for aggressive behavior among peers. Show that there are statistically significant correlations between the dimensions of victimization and aggression and also found that a secure attachment appears to be a protective factor for victimization and aggression and anxious attachment seems to relate to the victimization.

This paper presents a methodology to forecast the hourly and daily consumption in households assisted by cyber physical systems. The methodology was validated using a database of consumption of a set of 93 domestic consumers. Forecast tools used were based on Fast Fourier Series and Generalized Reduced Gradient. Both tools were tested and their forecast results were compared. The paper shows that both tools allow obtaining satisfactory results for energy consumption forecasting.

The variability in non-dispatchable power generation raises important challenges to the integration of renewable energy sources into the electricity power grid. This paper provides the coordinated trading of wind and photovoltaic energy assisted by a cyber-physical system for supporting management decisions to mitigate risks due to the wind and solar power variability, electricity prices, and financial penalties arising out the generation shortfall and surplus. The problem of wind-photovoltaic coordinated trading is formulated as a stochastic linear programming problem. The goal is to obtain the optimal bidding strategy that maximizes the total profit. The wind-photovoltaic coordinated operation is modelled and compared with the uncoordinated operation. A comparison of the models and relevant conclusions are drawn from an illustrative case study of the Iberian day-ahead electricity market.

This paper deals with the self-scheduling problem of a price-taker having wind and thermal power production and assisted by a cyber-physical system for supporting management decisions in a day-ahead electric energy market. The self-scheduling is regarded as a stochastic mixed-integer linear programming problem. Uncertainties on electricity price and wind power are considered through a set of scenarios. Thermal units are modelled by start-up and variable costs, furthermore constraints are considered, such as: ramp up/down and minimum up/down time limits. The stochastic mixed-integer linear programming problem allows a decision support for strategies advantaging from an effective wind and thermal mixed bidding. A case study is presented using data from the Iberian electricity market.

BULLYING- espectáculo/intervenção, é um relatório de estágio elaborado no contexto do curso de Mestrado de Teatro em Arte do Actor da Universidade de Évora pelo aluno 20584 Pedro Mendes. Dá conta da experiência curricular do mestrando enquanto actor numa companhia de teatro profissional, bem como de urna análise e pesquisa temática, processual e académica, por ele desenvolvidas e redigidas. O estágio de três meses foi realizado na ACTA- A Companhia de Teatro do Algarve, sedeada na cidade de Faro, e teve como objectivo a construção e consequente apresentação do espectáculo BULLYING, terceira produção artística da companhia de carácter pedagógico, nas diversas escolas básicas da região. Segundo a orientação da docente Ana Tamen, o discente abordou todo o objecto de estágio através de urna aproximação estética ao Teatro do Oprimido de Augusto Boal. _Summary: BULLYING- Show/lntervention, is an internship report, elaborated within the context of a Master's Degree in Theatre, «The Actor’s Art» - at the University of Évora by the student, number 20584, Pedro Mendes. This report contains the curricular experience of the student while acting for a professional theatre company, as well as an analysis and a thematic, procedure and academic research, developed and written by the student. The three-month internship was made at ACTA - A Companhia de Teatro do Algarve (Algarve's Theatre Company), established in the town of Faro. The development and presentation of the show BULLYING, is the third artistic educational production of the company, in several schools of the region. Under the guidance of the teacher Ana Tamen, the student meant to establish, through this report, an aesthetic connection between the work developed in this context and Augusto Boal’s ‘Teatro do Oprimido'.
