Progetto Ustica is an experiment in "civically-engaged game design" and addresses the Ustica Massacre ("Strage di Ustica"), where 81 people lost their lives as an air-to-air missile hit a civilian aircraft in 1980. Progetto Ustica has been developed as part of an Action Research effort with the objective of preserving and transmitting the historical memory of the event. With this post-mortem essay, we reflect on the game design challenges that Progetto Ustica faced, we introduce different conceptualizations of "memory" emerging from our design practice, and we synthesize some lessons learned (implications for design) towards other "civically-engaged games" for socio-cultural heritage.

Machine learning models have proven to be reliable methods in classification tasks. However, little research has been conducted on the classification of dwelling characteristics based on smart meter and weather data before. Gaining insights into dwelling characteristics, which comprise of the type of heating system used, the number of inhabitants, and the number of solar panels installed, can be helpful in creating or improving the policies to create new dwellings at nearly zero-energy standard. This paper compares different supervised machine learning algorithms, namely Logistic Regression, Support Vector Machine, K-Nearest Neighbor, and Long-short term memory, and methods used to correctly implement these algorithms. These methods include data pre-processing, model validation, and evaluation. Smart meter data, which was used to train several machine learning algorithms, was provided by Groene Mient. The models that were generated by the algorithms were compared on their performance. The results showed that the Long-short term memory performed the best with 96% accuracy. Cross Validation was used to validate the models, where 80% of the data was used for training purposes and 20% was used for testing purposes. Evaluation metrics were used to produce classification reports, which indicates that the Long-short term memory outperforms the compared models on the evaluation metrics for this specific problem.

Even though more than seventy-five years have passed since the end of WWII, its prominence in entertainment media productions along with the global emergence of memorial markers have contributed to its omnipresence in people’s minds. Nevertheless, the perception of this historical event is still far from reaching consensus as nations tend to interpret and remember episodes in accordance with their perspective, thus adding up to the complexity of WWII and of Holocaust memories. With this in mind, this article describes the idiosyncrasies of Portugal’s recent tribute and remembrance strategies for the victims of WWII. The country’s neutral status, along with a set of cultural and historical specifics, has led to the dissemination of tropes leading to the idea of Portugal as an inherently tolerant and mild-mannered nation. A perception that is often fostered by resorting to monuments, museums, tourism and leisure activities. Despite evidence provided, mostly, by recent academic studies and documentary films, these tropes continue to fuel Portuguese popular imagination and are still prevalent in some recently established WWII memory places.
