Door lexicale en morfo-syntactische patronen te documenteren onder P'urhepecha-sprekers in Mexico en de Amerikaanse diaspora, zal dit project de bronnen van taalvariatie onderzoeken. De daaropvolgende online dialectatlas zal dienen als een online bron voor sprekers, leerlingen en onderzoekers van de…

Tijdens de Masterdag van vrijdag 15 maart bezochten meer dan 750 uit binnen- en buitenland de Faculteit Geesteswetenschappen.

In Nederland bieden ongeveer 130 van de 700 middelbare scholen een tweetalige stroom aan. Toch is er nog maar weinig wetenschappelijk onderzoek naar CLIL (content and language integrated learning). Met haar proefschrift wil Evelyn van Kampen (promovendus bij het ICLON) bijdragen aan een beter begrip…

Dit project gaat over (1) hoe de strategieën die gebruikt worden om epistemiciteit uit te drukken verschillen in hun interpretatie en gebruik; (2) welke strategieën kunnen gecombineerd worden en tot welke effecten dit leidt; (3) wat de uitdrukking van (verschillende aspecten van) epistemiciteit ons…

Dit onderzoek gaat over hoe automatische gebarentaalherkenningstechnologie verder ontwikkeld kan worden om statische beelden en tekstuele beschrijvingen van gebaren te analyseren.

De prehistorie van communicatiemetaforen

Hoe zet Rusland propaganda in en wat kenmerkt Russische propaganda als het gaat om taal en argumentatie?

Dit onderzoek gaat over welke metaforen problemen veroorzaken in machinevertalingen en wanneer, waarom en voor wie.

Op 16 december 2021 verdedigde Lisanne van Houten het proefschrift 'Flexing the Slot Regime'. Het promotieonderzoek is begeleid door prof.dr. P. Mendes de Leon en prof. L. Pierallini (Luiss University Of Rome).

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

In this thesis, deep learning is studied from a statistical perspective. Convergence rates for the worst case risk bounds of neural network estimators are obtained in the classification, density estimation and linear regression model.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

Transplantation of labial salivary glands to the eyelids for patients with dry eye appears to give excellent results clinically.

Visualizing the internal structure is a crucial step in acquiring knowledge about the origin, state, and composition of cultural heritage artifacts. Among the most powerful techniques for exposing the interior of cultural heritage objects is computed tomography (CT), a technique that computationally…

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Due to their central physiological roles in living organisms, retaining beta-glycosidases have been the subject of tremendous research efforts to examine their structure/function relation using numerous biophysical and biochemical approaches.

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Enzymes are innately sensitive to changes in the amino acid sequence, which largely constrains their evolutionary potential, i.e., evolvability. This evolutionary burden can be alleviated in the presence of stabilizing mutations, which increase the buffering capacity of enzymes to tolerate mutations…
