Dr. Jelena Belic and Dr. Tom Theuns have each been awarded XS grants from the NWO to develop innovative lines of research. Dr. Belic’s project examines distinctive ways in which the deployment of digital technologies interferes with freedom, while Dr. Theuns explores the ideological tensions between…

Food waste is a defining inefficiency of the modern food system, with profound implications for resource use, climate change, and circular economy transitions. This dissertation examines food waste through two complementary lenses: the prevention of avoidable food waste and the valorization of unavoidable…

The emissions of the Chinese industrial sector alone comprise 24.1% of global emissions (7.8 GtCyr−1 in 2015). This makes Chinese industrial emissions of unique national and international relevance in climate policy. This study reports a literature survey that quantitatively describes the evolution…

LCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability.

The transition to electric vehicles (EVs) reduces vehicle emissions to combat climate change. EVs raise concerns regarding the production of lithium-ion batteries and related emissions; while batteries can also provide energy storage services for the electricity system.

To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

Low-carbon (LE) technologies have a significant potential to reduce the total carbon emissions in China.

The demand for neodymium-iron-boron (NdFeB) magnets is rapidly growing, while the neodymium supply chain is under pressure. Recycling can alleviate these issues. This thesis investigates the potential for deploying novel magnet recycling technologies and their environmental consequences.

IoT technology poses serval opportunities to supply chains. This thesis employs grey correlation and forecasting models, system dynamics, agent-based modeling, and ex-ante LCA to investigate and quantify the opportunities and risks of IoT-enabled sustainable supply chain operations from both industrial…

This thesis studied in depth the energy use and CO2 emissions of the industrial sector in China.

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

Understanding the water use of power production is an important step to both a sustainable energy transition and an improved understanding of water conservation measures. However, there are large differences across the literature that currently present barriers to decision making.

Global Environmental Extensions Multi-Regional Input-Output (EE-MRIO) analysis is often used to analyze how changes in global and national demand for products lead to socioeconomic and environmental impacts at the national level.

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

It is often claimed that social media can contribute to democratic decision-making by bringing politicians and citizens into dialogue with one another. But is this potential always realised, and how? Most researchers look at politicians and their online communication strategies. In this New Media &…

It is difficult to hold international organisations (IOs) accountable for human rights violations. Gisela Hirschmann (Institute of Political Science, Leiden University) introduces the concept of pluralist accountability, whereby third parties set the standards for IOs’ actions in relation to human rights,…

Following the fall of the fourth Rutte cabinet, Dutch Minister of Justice and Security Dilan Yesilgöz addressed the Dutch media about the ‘influx’ of family reunification applications by asylum permit holders. In her view, it would put enormous pressure on Dutch society and could jeopardise security.…

How can the support for a collaborative approach to global challenges be increased, in times when international organisations’ capacity to act is under threat? Gisela Hirschmann (Leiden University) and Cornelia Ulbert (University of Duisburg-Essen) suggest a number of options.

The smallness of Suriname, according to political scientist Wouter Veenendaal (Leiden University), strongly affects and shapes the nature of democracy in the country. On the one hand, clientelism ensures that members of each ethnic group included in power-sharing arrangements have access to state resources…

How to explain variation in the extent to which parliamentary voting behaviour follows the government–opposition divide? Party Politics article by Tom Louwerse et al.

It’s impossible to avoid, even in the Netherlands: the US will soon be going to the polls. Where does it come from, this fascination with US elections? PhD candidate Bram Eenink explains.

Cynthia van Vonno, political scientist at Leiden University, explains why individual MPs vote according to the party group line.

This open access book brings together an eclectic cast of scholars in related disciplines to examine ageing in the Soviet Union, covering the practice of geriatrics, the science of gerontology, and the experience of growing old. Chapters in the book focus on concepts and themes that analyse Soviet ageing…

How we think about and act on the usefulness of scientific research has epistemological and political implications: what knowledge consists of, how it comes about and to what ends. In this dissertation, I situate the usefulness of scientific research in concrete places for knowledge exchange. The exchange…

From corpus pragmatics and metapragmatics to accountability and intentions, and from conversational structure and im/politeness to the role of emotions in utterance interpretation, the short articles collected here represent not just the wide scope of Michael's own work but also a snapshot of the field,…

Dutch right-wing political party Forum for Democracy has repeatedly demonstrated that it has no lower limit when it comes to morals.
