In certain conditions, (part of) an oil spill can disappear from the water surface through a process called natural dispersion. One available oil spill response option is to enhance this process by addition of dispersants (chemical dispersion). An informed decision for such response requires insight in the oil slick size WITH and WITHOUT treatment. This thesis aims to enable such assessment of net effectiveness, by providing a strategy for modelling the dispersion process. A plunging jet test was developed for investigating entrainment and droplet breakup. Using this set up the relevance of oil layer thickness was proven and an algorithm to model droplet sizes of dispersed oil was defined. The findings were applied in a model simulating dispersion and resurfacing as well as the wind-driven differential transport between the floating slick and suspended droplets. The simulation outputs help assess the added value (or not) of dispersant application in reducing the surface oil slick size for different oil types and conditions.

The free market underpins our economy and our way of thinking around enterprise and value, but it is also a major factor in the sustainability problems that we now live with. Climate change, child labour and oil spills are just a few of the many problems associated with our economic activity and, although many companies have made an effort to produce more sustainably, the pace of change is much too slow. This engaging and accessible textbook teaches students the relationship between the economy and sustainability, assessing the hand of the free market on company behaviour and, ultimately, providing a framework for transition to a sustainable economy. Using case studies and optional assessment questions, this textbook explains to students what a market is at the macro level and then translates the effects of the market to industries and subsequently to the strategic choices of companies at the micro level. It adopts a model of 8 guiding principlesthat underpin the current free market economy and 8 guiding principles for the sustainable market economy. Switching these deeply held principles will be essential to any serious transition to a sustainable economy.

Closed loop or ‘circular’ production systems known as Circular Economy and Cradle to Cradle represent a unique opportunity to radically revise the currently wasteful system of production. One of the challenges of such systems is that circular products need to be both produced locally with minimum environmental footprint and simultaneously satisfy demand of global consumers. This article presents a literature review that describes the application of circular methodologies to education for sustainability, which has been slow to adopt circular systems to the curriculum. This article discusses how Bachelor and Master-level students apply their understanding of these frameworks to corporate case studies. Two assignment-related case studies are summarized, both of which analyze products that claim to be 'circular'. The students' research shows that the first case, which describes the impact of a hybrid material soda bottle, does not meet circularity criteria. The second case study, which describes products and applications of a mushroom-based material, is more sustainable. However, the students' research shows that the manufacturers have omitted transport from the environmental impact assessment and therefore the mushroom materials may not be as sustainable as the manufacturers claim. As these particular examples showed students how green advertising can be misleading, applying “ideal” circularity principles as part of experiential learning could strengthen the curriculum. Additionally, this article recommends that sustainable business curriculum should also focus on de-growth and steady-state economy, with these radical alternatives to production becoming a central focus of education of responsible citizens. https://doi.org/10.1016/j.jclepro.2019.02.005 LinkedIn: https://www.linkedin.com/in/helenkopnina/

This overview can be regarded as an atlas or travel guide with which the reader can follow a route along the various professorships. Chapter 2 centres on the professorships that are active in the field of Service Economy. Chapter 3 is dedicated to the professorships that are focussed on the field of Vital Region. Chapter 4 describes the professorships operating in the field of Smart Sustainable Industries. Chapter 5 deals with the professorships that are active in the field of the institution-wide themes of Design Based Education and Design Based Research. Lastly, in Chapter 6 we make an attempt to discover one or more connecting themes or procedures in the approach of the various professorships. This publication is not intended to give a definitive answer to the question as to what exactly NHL Stenden means by the concept of Design Based Research. The aim of this publication is to get an idea of everything that is happening in the NHL Stenden professorships and to pique one’s curiosity to find out more.

Two key air pollutants that affect asthma are ozone and particle pollution. Studies show a direct relationship between the number of deaths and hospitalizations for asthma and increases of particulate matter in the air, including dust, soot, fly ash, diesel exhaust particles, smoke, and sulfate aerosols. Cars are found to be a primary contributor to this problem. However, patient awareness of the link is limited. This chapter begins with a general discussion of vehicular dependency or ‘car culture’, and then focuses on the discussion of the effects of air pollution on asthma in the Netherlands. I argue that international organizations and patient organizations have not tended to put pressure on air-control, pollution-control or environmental standards agencies, or the actual polluters. While changes in air quality and the release of greenhouse gases are tied to practices like the massive corporate support for the ongoing use of motor vehicles and the increased prominence of ‘car culture’ globally, patient organizations seem more focused on treating the symptoms rather than addressing the ultimate causes of the disease. Consequently, I argue that to fully address the issue of asthma the international health organizations as well as national health ministries, patient organizations, and the general public must recognize the direct link between vehicular dependency and asthma. The chapter concludes with a recommendation for raising environmental health awareness by explicitly linking the vehicular dependency to the state of poor respiratory health. Strategic policy in the Netherlands then should explicitly link the present pattern of auto mobility to public health. https://onlinelibrary.wiley.com/doi/book/10.1002/9781118786949 LinkedIn: https://www.linkedin.com/in/helenkopnina/

This paper addresses the extraterritorial dimension of transnational corporations, focusing on the corporate accountability-deficit that characterizes the current International legal framework. The analysis looks at parent companies’ civil liability for environmental harm caused abroad. By introducing a selected number of foreign direct liability cases brought before European national courts, the paper investigates whether the binding environmental and human rights reporting obligations contained in Directive 2014/95/EU contribute to the determination of a parent company’s duty of care towards its overseas subsidiaries, and consequently establish their potential liability.

We summarize what we assess as the past year's most important findings within climate change research: limits to adaptation, vulnerability hotspots, new threats coming from the climate–health nexus, climate (im)mobility and security, sustainable practices for land use and finance, losses and damages, inclusive societal climate decisions and ways to overcome structural barriers to accelerate mitigation and limit global warming to below 2°C.

In this article, we elaborate on the role of dialogical learning in identity formation in the context of environmental education. First, we distinguish this kind of learning from conditioning and reproductive learning. We also show that identity learning is not self-evident and we point out the role of emotions. Using Dialogical Self Theory, we then suggest that individuals do not have an “identity hierarchy” but a dialogical self that attaches meaning to experiences in both conscious and unconscious ways. We describe the learning process that enables the dialogical self to develop itself, and we elaborate on the characteristics of a good dialogue. We conclude with some remarks expanding room for a dialogue that would foster identity learning. https://doi.org/10.3390/resources5010011 https://www.linkedin.com/in/helenkopnina/
