Happiness in advanced adulthood and the elderly
The purpose of this study was to critically analyse the role that positive emotions, flourishing and mindfulness have among the elderly. It was explored how these concepts can contribute to successful aging and higher levels of happiness in this population. To this end, we conducted a non-experimental correlational study with 329 participants, aged from 55 to 98 years. Questionnaires were used to collect data through the following instruments: a socio-demographic questionnaire, Mindful Attention Awareness Scale (MAAS), Satisfaction With Life Scale (SWLS) and PANAS (Positive and Negative Affect Schedule), FS (Flourishing scale), PST (Positivity test), MHI-5 (Mental Health Inventory -- 5).
Collaborative Governance in Portugal – Yes or No? A critical approach based on an empirical survey
Collaborative governance can be defined as a concerted type of decision-making and collective action in which government bodies and private sector stakeholders interact as equal partners with the aim of achieving outcomes of interest for both parties. In practical terms, this is a type of governance where special meetings and negotiations are held – typically in somewhat elitist and secretive settings – with the aim of defining shared responsibilities and benefits associated with joint public-private ventures. Academic authors in favour of the adoption of collaborative governance in Portugal tend to present a rather positive view on the merits of this approach. They argue that it is potenti…
Characterization and Modelization of Surface Net Radiation through Neural Networks
Artificial neural networks have shown to be a powerful tool for system modeling in a wide range of applications. In this chapter, the focus is on neural network applications to obtain qualitative/quantitative relationships between meteorological and soil parameters and net radiation, the latter being a significant term of the surface energy balance equation. By using a Multilayer Perceptron model an artificial neural network based on the above mentioned parameters, net radiation was estimated over a vineyard crop. A comparison has been made between the estimates provided by the Multilayer Perceptron and a linear regression model that only uses solar incoming shortwave radiation as input par…
