This project uses archaeological, literary and epigraphic evidence to investigate urban development in Roman-period North Africa, compiling this in a GIS-linked database in order to analyse the development of urban settlement spatially over time.

Op 10 november 2021 verdedigde Carmel van Niekerk-Jacobs het proefschrift 'Realising the right to reproduce with assistance in South Africa'. Het promotieonderzoek is begeleid door prof.dr. J.J. Sloth-Nielsen en prof.dr. T. Liefaard.

Almost three years after receiving her honorary doctorate, Dr Graça Machel returned to Leiden University. Over the course of two days she spoke with students, researchers, and other interested persons, about human rights – particularly those of women and children – in a world in which these are continually…

This project investigates the rich linguistic history of the crucial language groups in East Africa and includes a search for words that indicate earlier lost languages. These outcomes, combined with recent archaeological and genetic research, will contribute to a new understanding of East Africa’s…

Hoe beinvloedt economisch verval de democratische waarden en verhoudingen tussen groepen in Africa?

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…

VODAN Africa is begonnen als een platform om toegang te bieden tot kritieke data die Afrika nodig heeft om de nieuwe COVID-19 te bestrijden. Het initiatief werd geïnspireerd door de ervaring met de uitbraak van het ebolavirus in Liberia in 2014: vroege opsporing vereist tracering van contacten. Het…

In dit project wordt epistemiciteit onderzocht: hoe de kennis van de spreker en van de luisteraar in de grammatica wordt uitgedrukt. Dat laat zien hoe sprekers hun kennis organiseren en of de taal die ze spreken daar invloed op heeft.

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).

This thesis focuses on the social dimensions of crane and wetland conservation in rural landscapes in Kenya, Uganda and Zimbabwe.

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…

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

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.

Prematurely born neonates require, amongst others, pharmaceutical therapy. Dosing guidelines for these therapies are often based on data from term born neonates or older infants, while these are not necessarily similar to prematurely born neonates.

Electoral Systems and Turnout: Evidence From a Regression Discontinuity Design. In dit artikel, gepubliceerd op de website SAGE research methods, bespreken auteurs Jaroslaw Kantorowicz en Tobias M. Hlobil hoe een Regression Discontinuity Design uitgevoerd kan worden.

Vanaf de koloniale tijd tot heden hebben grote aantallen Javanen hun woonplaats verlaten om zich in andere delen van Indonesië of veel verder weg te vestigen. Vaak was deze spreiding gedwongen, vaak met traumatische gevolgen.

The project

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

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…

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.
