This booklet holds a collection of drawings, maps, schemes, collages, artistic impressions etc. which were made by students during an intense design moment in the project (re)CYCLE Limburg, which took place in December 2016. Students of Built Environment, Facility Management, Social Work and Health & Care cooperated in making designs and developing strategies for urban renewal in Kerkrade West (Province of Limburg, the Netherlands). The study focused on the importance of qualitative and shared public spaces. The local community (inhabitants, shopkeepers, entrepreneurs, municipality, housing corporation) was actively engaged by sharing knowledge and information, ideas and opinions. These reflections are part of the Limburg Action Lab (part of the Smart Urban Redesign Research Centre). It engages in research by design on innovative and tactical interventions in public space, that might enhance the identity, sustainability and socio-spatial structure of neighbourhoods.

The objective of this study is to evaluate the energetic, exergetic, sustainability, economic and environmental performances of a 4-cylinder turbodiesel aviation engine (TdAE) used on unmanned aerial vehicles for the take-off operation mode to assess the system with large aspects. Energy efficiency of the system is found as 43.158%, while exergy efficiency 40.655%. Thermoeconomic analysis gives information about the costs of the inlet and outlet energy and exergy flows of the engine. Hourly levelized total cost flow of the TdAE is found as 21.036 $/h, when the hourly fuel cost flow of the engine is found as 30.328 $/h. The waste exergy cost parameter is determined as 0.0144 MJ/h/$ from exergy cost-energy-mass (EXCEM) analysis, while it is estimated as 14.043 MJ/$ from modified-EXCEM analysis. Environmental damage cost analysis evaluates the cost formation of the exhaust emissions. The total environmental damage cost of the TdAE is computed as 12.895 $/h whilst specific environmental damage cost is determined as 0.054 $/MJ for 494.145 MJ/h TdAE power production. It is assessed that the main contributors to the environmental impact rate of the TdAE are the fuel consumption and the formation pollutants of combustion reaction.

Free newspapers may offer different news contents to different audiences, when compared with traditional, paid-for newspapers, but they, nevertheless, concentrate on news, and thereby provide society with information on current affairs. These papers have seen circulation rise until 2008; after that, a decline set in, leading to closures and often a monopoly situation in the mature European newspaper markets covered in our research. Free newspapers seem to follow a typical life cycle pattern, moving from growth to maturity, and to saturation and decline. Diversification strategies – home-delivery, weekend, sports, afternoon, and financial – have been disappointing so far. There is no evidence, however, of total extinction, indicating that there is room for at least one title – possibly two – in every market. The situation in the surveyed markets also suggests that a free newspaper may be a ‘natural’ monopoly.

This booklet contains the analyses and designs that were produced by international teams of students, designers and researchers on the revitalization of public space in the district of Kerkrade – West (Limburg, the Netherlands) in December 2017 during the International Design Workshop (re)CYCLE LIMBURG 2. It was partially built on knowledge, experiences and ideas from the preceding workshop in December 2016. The outcomes of the workshop are mainly presented in the form of drawings, maps, schemes, collages, artistic impressions etc. Both workshops were framed in the interdisciplinary project Kerkrade-West of Zuyd UAS and its Research Centre for Smart Urban ReDesign (SURD).

Worldwide, plastic cups are used for serving drinks. Some typical examples of large-scale consumption are large concerts and festivals. As a part of the BIOCAS project, which focusses on the valorization of biomass through various routes, a PHA biobased festival cup was developed and created to reduce the impact of current fossil plastics. The role of VHL was to assess the environmental impact. The aim of the report is to inform the BIOCAS-partners about the use of plastic cups, and address the environmental impact in comparison with other types of biobased plastic cups and fossil-based cups. This report can serve as a basis for making choices within all different types of (plastic/biobased) cups. Besides, it can be used as a public communication tool about the environmental impact of different types of (plastic/biobased) cup applications.

Cities are constantly in transition. Spatial production worldwide is generated by governments, business, developers, informal settlers, et cetera; sometimes cities expand, but increasingly there is a process of reurbanisation of existing urban patterns contronted with deterioration, dysfunctionality, or obsolescence. In many situations, funding, power and technology determine how the course of urbanisation. Communities, groups and individuals with limited access to funding, power and technology need empowerment to exercise their right to shape and improve their own evironment, while respecting health, equity and ecology. The research centre for Smart Urban Redesign (SURD) at Zuyd University of Applied Sciences seeks to work on this empowerment for communities. This study presents SURD’s approach to neighbourhood revitalisation.

One of the core elements of the Programme for the International Assessment of Adult Competencies (PIAAC) is a survey of adult skills. The survey measures adults’ proficiency in literacy, numeracy, and problem solving in technology-rich environments. Furthermore, the survey gathers data on how adults use their skills at home, at work and in the wider community. The second cycle of PIAAC will take place in 2021 and 2022. Preparations have started by the Numeracy Expert Group in reviewing the numeracy framework used in the first cycle and designing items which will be used to measure the numerate capabilities and numerate behavior of adults.

The purpose of this paper is to perform a metaphorical analysis of knowledge as energy. This paper is based on a theoretical research concerning the nature, perception, basic laws and challenges brought up by these fundamental concepts of knowledge and energy. The metaphorical analysis of knowledge and intellectual capital has been initiated by Daniel Andriessen and his findings have been presented in several seminal works (Andriessen, 2006; 2008; Andriessen and Boom, 2007). In his work, Andriessen concluded we need to find new metaphors for knowledge. In our theoretical research we shall consider the knowledge as energy metaphor, with energy as the source domain, and knowledge as the target domain, and we are interested in identifying the metaphorical semantic kernel and the limitations of this analysis. The semantic kernel contains: (1) the concept of field as a nonuniform and nonlinear distribution of knowledge; (2) dynamics of potential and kinetic forms of manifestations; (3) dynamics of work and heat, and (4) entropy and syntropy process characteristics. Limitations of this analysis come from the conservation laws of energy transformation which cannot be applied to the knowledge domain.

Citizens regularly search the Web to make informed decisions on daily life questions, like online purchases, but how they reason with the results is unknown. This reasoning involves engaging with data in ways that require statistical literacy, which is crucial for navigating contemporary data. However, many adults struggle to critically evaluate and interpret such data and make data-informed decisions. Existing literature provides limited insight into how citizens engage with web-sourced information. We investigated: How do adults reason statistically with web-search results to answer daily life questions? In this case study, we observed and interviewed three vocationally educated adults searching for products or mortgages. Unlike data producers, consumers handle pre-existing, often ambiguous data with unclear populations and no single dataset. Participants encountered unstructured (web links) and structured data (prices). We analysed their reasoning and the process of preparing data, which is part of data-ing. Key data-ing actions included judging relevance and trustworthiness of the data and using proxy variables when relevant data were missing (e.g., price for product quality). Participants’ statistical reasoning was mainly informal. For example, they reasoned about association but did not calculate a measure of it, nor assess underlying distributions. This study theoretically contributes to understanding data-ing and why contemporary data may necessitate updating the investigative cycle. As current education focuses mainly on producers’ tasks, we advocate including consumers’ tasks by using authentic contexts (e.g., music, environment, deferred payment) to promote data exploration, informal statistical reasoning, and critical web-search skills—including selecting and filtering information, identifying bias, and evaluating sources.
