Context-aware emotion-based model for group decision making

Involving groups in important management processes such as decision making has several advantages. By discussing and combining ideas, counter ideas, critical opinions, identified constraints, and alternatives, a group of individuals can test potentially better solutions, sometimes in the form of new products, services, and plans. In the past few decades, operations research, AI, and computer science have had tremendous success creating software systems that can achieve optimal solutions, even for complex problems. The only drawback is that people don’t always agree with these solutions. Sometimes this dissatisfaction is due to an incorrect parameterization of the problem. Nevertheless, the reasons people don’t like a solution might not be quantifiable, because those reasons are often based on aspects such as emotion, mood, and personality. At the same time, monolithic individual decisionsupport systems centered on optimizing solutions are being replaced by collaborative systems and group decision-support systems (GDSSs) that focus more on establishing connections between people in organizations. These systems follow a kind of social paradigm. Combining both optimization- and socialcentered approaches is a topic of current research. However, even if such a hybrid approach can be developed, it will still miss an essential point: the emotional nature of group participants in decision-making tasks. We’ve developed a context-aware emotion based model to design intelligent agents for group decision-making processes. To evaluate this model, we’ve incorporated it in an agent-based simulator called ABS4GD (Agent-Based Simulation for Group Decision), which we developed. This multiagent simulator considers emotion- and argument based factors while supporting group decision-making processes. Experiments show that agents endowed with emotional awareness achieve agreements more quickly than those without such awareness. Hence, participant agents that integrate emotional factors in their judgments can be more successful because, in exchanging arguments with other agents, they consider the emotional nature of group decision making.

Risk Acceptance in the Furniture Sector: Analysis of Acceptance Level and Relevant Influence Factors

Risk acceptance has been broadly discussed in relation to hazardous risk activities and/or technologies. A better understanding of risk acceptance in occupational settings is also important; however, studies on this topic are scarce. It seems important to understand the level of risk that stakeholders consider sufficiently low, how stakeholders form their opinion about risk, and why they adopt a certain attitude toward risk. Accordingly, the aim of this study is to examine risk acceptance in regard to occupational accidents in furniture industries. The safety climate analysis was conducted through the application of the Safety Climate in Wood Industries questionnaire. Judgments about risk acceptance, trust, risk perception, benefit perception, emotions, and moral values were measured. Several models were tested to explain occupational risk acceptance. The results showed that the level of risk acceptance decreased as the risk level increased. High-risk and death scenarios were assessed as unacceptable. Risk perception, emotions, and trust had an important influence on risk acceptance. Safety climate was correlated with risk acceptance and other variables that influence risk acceptance. These results are important for the risk assessment process in terms of defining risk acceptance criteria and strategies to reduce risks.

Relatório de estágio em educação pré-escolar e ensino do 1º ciclo do ensino básico

O presente relatório de estágio de qualificação profissional surge como forma de explanar o trabalho desenvolvido ao longo da prática pedagógica, pois o período de estágio apresenta-se como uma oportunidade fulcral para o desenvolvimento e experimentação de métodos e estratégias que colocam, muitas vezes, em questão conceções e preconceitos inerentes ao processo de ensino-aprendizagem. Sendo que os estagiários necessitam de oportunidades que contribuam “para a construção da sua própria aprendizagem” (Portugal, 2012, p. 100). Este contém análises e reflexões das práticas desenvolvidas e opções tomadas durante o estágio, tendo por base uma metodologia de investigação-ação na medida em que o trabalho realizado direcionou-se para a necessidade de transformação social. Neste sentido fomentou-se o questionamento reflexivo para melhoramento das práticas. Este estágio foi realizado em díade e apoiado em estratégias como as narrativas colaborativas, as planificações semanais, a avaliação reguladora e a supervisão. O presente encontra-se dividido em duas componentes, uma mais teórica, à qual se convoca autores e documentos legais para fundamentar a componente seguinte que é mais prática, onde se analisa as práticas desenvolvidas ao longo do ano letivo.
