Goed werkgeverschap is net als goed werknemerschap een open norm. Daarmee is het onduidelijk en onzeker waar werkgevers zich op dienen te richten en welke rechten (en plichten) werknemers hebben in dat verband. De doelstelling van dit onderzoek is om invulling te geven aan de norm goed werkgeverschap…

Learning from small data sets in machine learning is a crucial challenge, especially when dealing with data imbalances and anomaly detection. This thesis delves into the challenges and methodologies of learning from small datasets in machine learning, with a particular focus on addressing data imbalances…

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

Het doel van dit proefschrift was om mogelijke risicofactoren voor overgewicht in de vroege kindertijd te ontdekken die als basis kunnen worden gebruikt voor het ontwikkelen van opvoedinterventies voor het verminderen van overgewicht.

De onderzoeksgroep Organizational & Entrepreneurial Behavior onderzoekt het gedrag van individuen en groepen die in organisaties werken, organisaties starten, of organisaties leiden, met als doel om organisatorische praktijken te informeren. Door zich te concentreren op het gedrag van (groepen) werknemers,…

In this thesis, we study different curved single crystals because of the diversity of surface structures across their curvature.

In this top-rated course, you will learn how the European Union prepares and decides on policy, and how policy is transferred to member states and implemented by various authorities. It discusses the challenges of the European multi-level governance structure and the main causes of policy failure or…

Patients share valuable advice and experiences with their peers in online patient discussion groups.

In dit artikel onderzoeken Wout Broekema, Wouter Jong en Sara Perlstein het ontwerp en de beoordeling van crisisonderzoeken vanuit een leerperspectief.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

This dissertation presents new cryptographic protocols, which can be divided into two families.

Throughout the history of computer science, a major challenge has been how to assert that software is free of bugs and works as intended. Software bugs can lead to serious negative impacts on any software system. Throughout the main body of the thesis, we implemented a series of studies on exploring…

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

Materials balances have been used in the recent past for the analysis of substance oriented environmental problems and the formulation of measures for environmental policy. In this study an integrated tool, based on the materials balance principle, has been developed for the analysis of both environmental…

The intracluster medium (ICM) is a hot, tenuous and X-ray emitting gas that pervades galaxy clusters.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

Developing robust algorithms and theory for establishing cause-effect relationships from observational data that scale up to large data sets

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

Wat doe je als je iets te weten wilt komen? Tegenwoordig gebruikt men voornamelijk het internet om informatie te verkrijgen. Een lezer moet deze informatie vaak uit meerdere bronnen halen en die bronnen met elkaar in verband brengen, om zo een compleet plaatje te vormen van het onderwerp. Soms is de…

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

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

This Thesis describes the synthesis of D-alanylated ribitol-based wall teichoic acids from S. aureus to probe their interaction with immune-binding partners.

For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.
