This paper starts from the proposition that concern conflicts can be powerful starting points for user-centered design processes. Our focus is on the challenge to identify conflicting concerns that are both inspiring and relevant in the context of use, or in the user’s general context of life. First, three main ingredients of concern conflict...

The purpose of this paper is to increase our understanding of how insights in conflicting concerns can be used as an approach to design for subjective well-being. This is done through examining qualities of a conflict experience across three life domains: food, procrastination, and safe sex. Ten participants from various age groups and...

In this paper a design approach is introduced for designing products to increase happiness. Happiness reflects the degree to which people’s concerns are fulfilled. Based on this fact, a framework of all human concerns was created. After that, the framework was applied to a telehomecare case. Telehomecare products release the pressure on...

Current research in the field of performance measurement hasn't presented a rigorous composite indicator for quantifying company performance, with environmental indicators for automobile companies. This paper aims to construct this missing composite indicator. A new approach is developed, including techniques of fuzzy logic, analytic network...

Dependency solving is a hard (NP-complete) problem in all non-trivial component models due to either mutually incompatible versions of the same packages or explicitly declared package conflicts. As such, software upgrade planning needs to rely on highly specialized dependency solvers, lest falling into pitfalls such as incompleteness - a...

Recent research has shown that explanations serve as an important means to increase transparency in group recommendations while also increasing users' privacy concerns. However, it is currently unclear what personal and contextual factors affect users' privacy concerns about various types of personal information. This paper studies the effect...

Explanations can help users to better understand why items have been recommended. Additionally, explanations for group recommender systems need to consider further goals than single-user recommender systems. For example, we need to balance group members' need for privacy with their need for transparency, since a transparent explanation might...

Whereas in market-driven situations the private parties have an interest in driving innovations towards implementation, in the case of public concerns, it is often the public concern that initiates the innovation process. The issue for the public funding agencies is then to stimulate idea generation and the process towards implementation and...

Evolution of software systems accounts for the largest part of their lifecycle and costs. Software engineers therefore, more often than developing new systems, work on complex, existing ones that they have to understand in order to modify them. Understanding such systems requires insight into the various concerns the systems implement, many of...

Crosscutting concerns are phenomena that are present in almost any (embedded) software system. They arise if the implementation of a concern "a requirement or design decision" does not fit neatly into the modular decomposition of a software system. A crosscutting concern cannot be confined to a single modular unit and therefore becomes scattered...

Company performance measurement is fundamental for decision-makers to monitor a company's performance and to solve management problems. The evolution of company performance measurement tools started from a pure financial-biased framework. The first generation of company performance measurement tools was achieved through supplementing the...

The purpose of this paper is to introduce the concept of conflicting concerns to emotion-driven design and to demonstrate their translation into emotionally appealing design concepts. People have an endless number of concerns associated with everyday activities, which are challenging, if not impossible, to satisfy simultaneously. Therefore,...

Personal dilemmas are inspiring phenomena, which can stimulate design creativity and reflection on users’ goals and values. This paper aims to provide an overview of the main challenges involved in Dilemma-Driven Design (DDD). We first introduce three main activities performed when designing with dilemmas: Identifying dilemmas (discovery),...

Efficiently allocating scarce healthcare resources requires nuanced understanding of individual and collective interests as well as relative concerns, which may overlap or conflict. This paper is the first to empirically investigate whether and to what extent self-interest (SI), positional concerns (PC) and distributional considerations (DC)...

Digestate is a rich source of nutrients that can be applied in agricultural fields as fertilizer or irrigation water. However, most of the research about application of digestate have focused on its agronomic properties and neglected the potential harm of the presence of contaminants of emerging concern (CECs). Aadvanced oxidation processes ...

Water authorities and drinking water companies are challenged with the question if, where and how to abate contaminants of emerging concern in the urban water cycle. The most effective strategy under given conditions is often unclear to these stakeholders as it requires insight into several aspects of the contaminants such as sources, properties...

The present research explored to what extent user engagement in proactive recommendation scenarios is influenced by the accuracy of recommendations, concerns with information privacy, and trait personality. We hypothesized that people’s self-reported information privacy concerns would matter more when they received accurate (vs. inaccurate)...

Hotel developers incorporate green building design to save on capital and operation cost. Hotel operators adopt green practice to affect tourists’ intention of staying (IoS). This paper recognises the important contribution of green building design and eco-service provision to green hotels. It investigates the internal relationships of...

Removal of contaminants of emerging concern (CECs) from municipal wastewater is becoming more and more important. On-site regeneration of exhausted adsorbents can be the key to practical applications. In this study, ozone-based regeneration of granular zeolites loaded with acetaminophen (ACE) was investigated. The adsorption capacity of ACE was...

Open data promotes transparency and accountability as everyone can analyse it. Law enforcement and the judiciary are increasingly making data available, to increase trust and confidence in the criminal justice system. Due to privacy legislation, judicial open data — like court judgements — in Europe is usually anonymized. And even if the...
