This thesis focuses on data found in the field of computational drug discovery. New insight can be obtained by applying machine learning in various ways and in a variety of domains. Two studies delved into the application of proteochemometrics (PCM), a machine learning technique that can be used to…

A central and much debated topic in the study of language acquisition concerns the nature of the learning mechanisms that are required. Are the computational and learning mechanisms that guide learning about language structure special and specific to language or humans?

The literature indicates that teacher professional development and learning may be improved by using formative assessment procedures. This thesis focuses on a specific form of formative assessment, negotiated assessment, which is characterised by the exchange of views between assessor and assessee and…

In design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance…

Galikyan’s dissertation examines how the multidimensionality of learner­learner interaction data and the multifacetedness of learner-learner interaction itself impact the measurement of learner-learner interaction in digital learning environments.

You can ask virtual assistant Siri about the weather, but you can’t have a real conversation with it yet. You can’t refer to anything that’s been said before, or ask the system why it says what it says. Stephan Raaijmakers, Professor by Special Appointment from TNO, hopes to change this.

With the emergence of online social networks (OSNs), the way people create and share information has changed, which becomes faster and broader than traditional social media.

This thesis addresses questions on effectively using variational quantum circuits for machine learning tasks.

Recently, the booklet 'Blended Learning, het versterken van het onderwijs op de Universiteit Leiden' has been launched. Sonja Wagenaar, educational adviser at ICLON, was project manager of the three-year Blended Learning Program in which blended learning training was implemented in the studies Psychology,…

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

What are the 'dark' components of the universe?

We are cosmologists, in other words we use physics to study the Universe, how it started and evolved into the structure that we observe around us.

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

The topic of this study is the portfolio that is being used in a teacher education institute as an instrument for stimulating reflection on their development as teachers by student teachers.

When literature, cultural aspects, and data-driven language learning meet in a classroom.

The aim of this project is to develop accurate but interpretable ensemble learning methods for high-dimensional multi-domain data.

In this research project characteristics of effective instructional development were identified that are appealing to medical teachers and relevant for medical education.

What are best practices for teaching students to engage with 'wicked' problems?

Green infrastrucuture (GI) like urban farm and green roofs could provide many beneficial functions in cities. These include for example food production, flood prevention or increasing biodiversity. MultiGreen project aims at developing an integrated modelling tool to support…

Discover the connection between skateboarding and sensory ethnography in 32 of The Routledge International Handbook of Sensory Ethnography as part of the Multi-modal sensory ethnography.

Generally the data from remote sensing surveys - the scanning of the earth by satellite or aircraft in order to obtain information about it - is screened manually in archaeology. However, constant monitoring of the earth's surface causes a huge influx of data of high complexity and high quality. To…

This dissertation aims to establish a dialogue between ethnomusicology (more specifically indigenous organology), the anthropology of art and the culture of the Apinaye peoples, in order to understand how the musical objects of these peoples are learned and taught, and thus to understand its musical…

Drawing is one of the most unique human behaviours. Like language, drawing is a mode of communication and a cognitive tool that from an early age allows us to interact with others. Is the early development of drawing skill influenced by the social environment? If so, how?

This study explores public leaders’ organizational learning orientation in the wake of a crisis. More precisely, we study the association between public leaders’ public service motivation and their learning orientation (instrumental versus political).

Beginning teachers often experience difficulties making activating lessons. This study investigates how and if the practical teaching model can offer them a hand in learning to design lessons.

Serge Rombouts is a physicist whose PhD thesis was about functional MRI (fMRI). This visualises activity in regions of the brain. The appealing images of glowing brain regions that emerge from the computer are the result of calculations. According to Rombouts, this isn’t proper artificial intelligence.…

Some examples of research questions include: What framework of circular strategies should local practitioners use? How should practitioners organize their monitoring of the circular economy activities in the region of interest? What are the main products that have the most circular potential in the…

Research at the Leiden Institute of Physics (LION) is foundational and curiosity driven. All our scientists share a desire to increase the knowledge of the world around us, in an open atmosphere of inquiry from which innovative ideas emerge that provide applications and value for society.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

Leiden Observatory is going to use a new technique to carry out calculations on gravitational lensing measurements. They will do this is the context of research into the formation of elliptical galaxies. Alessandro Sonnenfeld (University of Tokyo) who developed this technique joined the research team…

This doctoral thesis comprises four studies on the content and structure of physics teachers’ belief systems about teaching and learning physics in secondary education in the Netherlands.

This book is the first comparative study of estimative intelligence and strategic surprise in a European context, complementing and testing insights from previous studies centred on the United States. It does extensive empirical analysis of open-source material and interviews in relation to three cases…

People with a mild intellectual disability (MID) experience more loneliness than people without MID. In the COLLELO project, researchers from social and humanities disciplines collaborate with people with MID and their (in)formal networks to create an (online) learning community that aims to understand…

Top scientists of three Dutch universities are working on software and systems for quantum computers. Researchers of the Leiden Institute of Advanced Computer Science (LIACS) and the Leiden Institute of Physics (LION) are developing new algorithms to make those super computers work. The coming years,…
