An automatic multi-tissue human fetal brain segmentation benchmark using the Fetal Tissue Annotation Dataset.

It is critical to quantitatively analyse the developing human fetal brain in order to fully understand neurodevelopment in both normal fetuses and those with congenital disorders. To facilitate this analysis, automatic multi-tissue fetal brain segmentation algorithms are needed, which in turn requires open datasets of segmented fetal brains. Here we introduce a publicly available dataset of 50 manually segmented pathological and non-pathological fetal magnetic resonance brain volume reconstructions across a range of gestational ages (20 to 33 weeks) into 7 different tissue categories (external cerebrospinal fluid, grey matter, white matter, ventricles, cerebellum, deep grey matter, brainstem/spinal cord). In addition, we quantitatively evaluate the accuracy of several automatic multi-tissue segmentation algorithms of the developing human fetal brain. Four research groups participated, submitting a total of 10 algorithms, demonstrating the benefits the dataset for the development of automatic algorithms

Read All About It! Understanding the Role of Media in Economic Development

This paper explores the role of media in economic development. In particular, we seek to outline the conditions under which the media contributes to the successful adoption of policies aimed at economic progress. Our core thesis is that successful economic development requires the coordination of efforts by politicians with the interests of the populace on policies that bring about economic growth. However, the nature of the relationship between political actors in charge of reform is characterized by a conflict of interests. The role of media as a key mechanism for transforming these situations of conflict into situations of coordination between politicians and the populace is analyzed. Specifically, we consider four factors - media autonomy, legal structure, quality of the media and consumer demand - and how they impact media as a coordination-enhancing mechanism.
