This study examines an inconsistency between an attitude and a behaviour: non-use of contraception among people who are trying to get pregnant. More than one in four people in that situation report using contraception 'sometimes' or 'always' and consequently face the risk of pregnancy. We test three potential explanations: acceptability of having (further) children; perceived low pregnancy risk; and perceived social pressure.

In neonates, where functional MRI is limited to very few paradigms, rsfMRI was shown to be a relevant tool to explore regional interactions of brain networks. However, to identify the resting state networks, data needs to be carefully processed to reduce artifacts compromising the interpretation of results.

Both modified LiviaNET and HyperDense-Net performed well at a prior competition segmenting 6-month-old infant magnetic resonance images, but neonatal cerebral tissue type identification is challenging given its uniquely inverted tissue contrasts. The current study aims to evaluate the two architectures to segment neonatal brain tissue types at term equivalent age.
