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.

Many organizations have undergone substantial reorganization in the last decade. They re-engineered their business processes and exchanged proprietary, not integrated applications for more standard solutions. Integration of structured data in relational data bases has improved documentation of business transactions and increased data quality. But almost 90% of the information that organizations manage is unstructured, can not easily be integrated into a traditional database. Just like structured data, unstructured information in organizations are records, meant and used as evidence for organizational actions and transactions. Governments, courts and other stakeholders are making increasing demands for the trustworthiness of records. This is part of a long-term trend toward defining what accountability means in a digital era. An analysis of literature of information science, organization science and archival science illustrates that for accountability, reconstruction of the past is essential. Hypothesis of this paper is that for the reconstruction of the past each organization needs (at least) a combination of three mechanisms: enterprise records management, organizational memory and records auditing. Enterprise records management ensures that records meet the for accountability necessary quality requirements: integrity, authenticity, controllability and historicity. These requirements ensure records that can be trusted. Trusted records enhance the possibility of reconstructing the past. The organizational memory ensures that trusted records are preserved for as long as is necessary to comply to accountability regulations. It provides an information and communication technology infrastructure to (indefinitely) store those records and to keep them accessible. Records auditing audits enterprise records management and organizational memory to assess the possibility to reconstruct past organizational actions and transactions. These mechanisms ensure that organizations have a documented understanding of: the processing of actions and transactions within business processes; the dissemination of trusted records; the way the organization accounts for the actions and transactions within its business processes; and the reconstruction of actions and transactions from business processes over time. This understanding is important for the reconstruction of the past in digitized organizations and improve organizational accountability.

They ensure records that can be trusted and enhance the possibilities for the reconstruction of the past. The organizational memory ensures that trusted records are preserved for as long as is necessary to comply with accountability regulations. It provides an ICT infrastructure to (indefinitely) store those records and to keep them accessible. Records auditing researches the first two mentioned mechanisms to assess the possibility to reconstruct past organizational actions and transactions. These mechanisms ensure that organizations have a documented understanding of [1] the processing of actions and transactions within business processes; [2] the dissemination of trusted records; [3] the way the organization accounts for the actions and transactions within its business processes; and [4] the reconstruction of actions and transactions from business processes over time. This understanding is crucial for the reconstruction of the past and for organizational accountability.

Many visitor studies make social background variables the central point of departure to explain participation patterns. How the past is 'staged', however, also has an influence on those to whom it appeals. This relational perspective calls for new conceptual tools to grasp empirical reality. Inspired by the historical philosophy of Georg Simmel and the literary theory of Mikhail Bakhtin a number of concepts which enable us to grasp the subtle relationship between museum presentations and visitors are presented. Bakhtin's notion of chronotopy serves as a key concept. By linking museum presentations and visitor perceptions with each other, it is also possible to identify certain tendencies within the contemporary museum landscape.

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.

Cybersecurity threat and incident managers in large organizations, especially in the financial sector, are confronted more and more with an increase in volume and complexity of threats and incidents. At the same time, these managers have to deal with many internal processes and criteria, in addition to requirements from external parties, such as regulators that pose an additional challenge to handling threats and incidents. Little research has been carried out to understand to what extent decision support can aid these professionals in managing threats and incidents. The purpose of this research was to develop decision support for cybersecurity threat and incident managers in the financial sector. To this end, we carried out a cognitive task analysis and the first two phases of a cognitive work analysis, based on two rounds of in-depth interviews with ten professionals from three financial institutions. Our results show that decision support should address the problem of balancing the bigger picture with details. That is, being able to simultaneously keep the broader operational context in mind as well as adequately investigating, containing and remediating a cyberattack. In close consultation with the three financial institutions involved, we developed a critical-thinking memory aid that follows typical incident response process steps, but adds big picture elements and critical thinking steps. This should make cybersecurity threat and incident managers more aware of the broader operational implications of threats and incidents while keeping a critical mindset. Although a summative evaluation was beyond the scope of the present research, we conducted iterative formative evaluations of the memory aid that show its potential.

This investigation explores relations between 1) a theory of human cognition, called Embodied Cognition, 2) the design of interactive systems and 3) the practice of ‘creative group meetings’ (of which the so-called ‘brainstorm’ is perhaps the best-known example). The investigation is one of Research-through-Design (Overbeeke et al., 2006). This means that, together with students and external stakeholders, I designed two interactive prototypes. Both systems contain a ‘mix’ of both physical and digital forms. Both are designed to be tools in creative meeting sessions, or brainstorms. The tools are meant to form a natural, element in the physical meeting space. The function of these devices is to support the formation of shared insight: that is, the tools should support the process by which participants together, during the activity, get a better grip on the design challenge that they are faced with. Over a series of iterations I reflected on the design process and outcome, and investigated how users interacted with the prototypes.

Valuation of heritage buildings is usually performed by architectural-historical experts, who use a typology of heritage values based on conservation philosophy. Increasingly, social and spirituality values are included in heritage assessment frameworks.What happens to valuation systems when external events influence the chances of survival of heritage buildings, such as earthquakes induced by gas extraction in the Netherlands? While the mining company uses a narrow economic perspective on value, the public fears for loss of character of their historic towns. New safety regulations constitute a new and even stronger threat to heritage buildings. Recently, a heritage assessment framework was published, to help with value assessments in the affected region. In this paper, we compare experts’ and laypersons’ values by analyzing the new assessment framework as well as public documents. We conclude that heritage value assessments should incorporate social values, including memories and symbolic meanings, to create a balanced valuation system.

It will be hard to find a Dutchmen under 50 years old who is not able to understand and speak English. Dutch pupils in secondary education spend about 4 hours a week studying grammar, reading texts, listening to conversations and giving presentations, all in English and that for four to six years. They even study cultural and historical aspects of the English speaking world. Music, films and playing online-computer games all add to a better understanding of the English language. The quality of most Dutch vowels and consonants are quite close to the quality of many English vowels and consonants. Most of the time an English utterance produced with Dutch vowel and consonant qualities will still be easily understood by native speakers of English. Phonological interference does not automatically make a Dutchman’s English unintelligible. However, why is it so easy to recognise a Dutchman as being Dutch while speaking English? Would it not be worthwhile to try and achieve a near-native accent for our pupils and students?
