Background: Construction work, squares, busy sidewalks, road crossings and hasty cyclists - these are just a few of the many challenges visually impaired people (VI) encounter when navigating through urban environments. Especially unknown routes require so much concentration and energy, that VI often choose to stay at home or to travel with assistance. The EyeBeacons project investigates how a wayfinding smartphone app for VI can support independent travel.Methods: Two clickable prototypes of a wayfinding app for VI were created based on the user-requirements from a pilot study. The first app contained many personalization options for route planning, while the second app used pre-defined user profiles (wizard) to create personal routes. Both apps were evaluated in a co-creation workshop of 16 participants, consisting of VI (6), VI care professionals (5) and UX/ICT experts (5). During the workshop, several UX design tools (e.g., customer journey maps) were used to evaluate the apps.Findings: Our preliminary results show that both apps were considered to have additional value for VI’s current route planning and wayfinding practices. Surprisingly, the first app, which offered many personalization options but consequently included more interaction steps, was preferred over the optimized wizard design of the second app. The main reason for this choice, was the limited insight on the reasoning behind route selection. Key features that participants missed in both prototype apps included for example, a function to repeat navigation cues on request.Discussion: This study provides valuable new insights for the design of wayfinding apps that allow VI to navigate safely and independently through challenging urban environments. Furthermore, we found that co-creation works well with the target group using common UX design methods as long as some extra facilitation is provided to the VI. By using clickable prototypes, both VI and professionals were able to experience and evaluate the design prototypes.
In case of a major cyber incident, organizations usually rely on external providers of Cyber Incident Response (CIR) services. CIR consultants operate in a dynamic and constantly changing environment in which they must actively engage in information management and problem solving while adapting to complex circumstances. In this challenging environment CIR consultants need to make critical decisions about what to advise clients that are impacted by a major cyber incident. Despite its relevance, CIR decision making is an understudied topic. The objective of this preliminary investigation is therefore to understand what decision-making strategies experienced CIR consultants use during challenging incidents and to offer suggestions for training and decision-aiding. A general understanding of operational decision making under pressure, uncertainty, and high stakes was established by reviewing the body of knowledge known as Naturalistic Decision Making (NDM). The general conclusion of NDM research is that experts usually make adequate decisions based on (fast) recognition of the situation and applying the most obvious (default) response pattern that has worked in similar situations in the past. In exceptional situations, however, this way of recognition-primed decision-making results in suboptimal decisions as experts are likely to miss conflicting cues once the situation is quickly recognized under pressure. Understanding the default response pattern and the rare occasions in which this response pattern could be ineffective is therefore key for improving and aiding cyber incident response decision making. Therefore, we interviewed six experienced CIR consultants and used the critical decision method (CDM) to learn how they made decisions under challenging conditions. The main conclusion is that the default response pattern for CIR consultants during cyber breaches is to reduce uncertainty as much as possible by gathering and investigating data and thus delay decision making about eradication until the investigation is completed. According to the respondents, this strategy usually works well and provides the most assurance that the threat actor can be completely removed from the network. However, the majority of respondents could recall at least one case in which this strategy (in hindsight) resulted in unnecessary theft of data or damage. Interestingly, this finding is strikingly different from other operational decision-making domains such as the military, police and fire service in which there is a general tendency to act rapidly instead of searching for more information. The main advice is that training and decision aiding of (novice) cyber incident responders should be aimed at the following: (a) make cyber incident responders aware of how recognition-primed decision making works; (b) discuss the default response strategy that typically works well in several scenarios; (c) explain the exception and how the exception can be recognized; (d) provide alternative response strategies that work better in exceptional situations.
Project objectives Radicalisation research leads to ethical and legal questions and issues. These issues need to be addressed in way that helps the project progress in ethically and legally acceptable manner. Description of Work The legal analysis in SAFIRE addressed questions such as which behavior associated with radicalisation is criminal behaviour. The ethical issues were addressed throughout the project in close cooperation between the ethicists and the researchers using a method called ethical parallel research. Results A legal analysis was made about criminal law and radicalisation. During the project lively discussions were held in the research team about ethical issues. An ethical justification for interventions in radicalisation processes has been written. With regard to research ethics: An indirect informed consent procedure for interviews with (former) radicals has been designed. Practical guidelines to prevent obtaining information that could lead to indirect identification of respondents were developed.
In Europe we consume 50 million tonnes of plastic a year. The use of plastic has increased fiftyfold in fifty years and the growth continues. Collecting and recycling plastic is thus essential to avoid the pollution of the land and sea. However, generally, post-consumer plastics have very low recycling rates, at present only 7% of plastic used in Europe comes from recycled polymers. Polyethylene terephthalate (PET) is one of the most recycled materials; in 2017 more than 57% of PET bottles were recycled in Europe, used in both packaging and fibre applications. Especially transparent PET bottles have high collecting and recycling rates over Europe. However, the plastics have very different value depending on their colour. If the plastic is even very lightly coloured, the plastic will lose a large percentage of its value. Decolouring plastic is complicated and currently no efficient and economically viable system exists. FT Innovations, a SME with the core-expertise in extraction, sees potential in developing a sustainable decolouration process with a new extraction technology, which offers significant potential in replacing hazardous, relatively expensive and environmentally damaging organic solvents that are currently used on decolouration. Avans has relevant expertise in both (biobased) plastic colourants and the extraction techniques as demonstrated in previous projects, and therefore FT innovations approached Avans with the request to assist in the feasibility study. The consortium is further strengthen by CCT Oss with their strong industrial know-how of colourants and their use in plastics and Plastic Company with their core activity on recycling of PET and other plastic materials.
