Asparagopsis taxiformis (AT) is a source of multiple halogenated compounds and, in a limited number of studies, has been shown to decrease enteric CH4 production in vitro and in vivo. Similarly, oregano has also been suggested as a potential CH4 mitigating agent. This study consisted of 2 in vitro and 2 in vivo experiments. Experiment 1 (Exp. 1) was aimed at establishing the effect of AT on total gas production and CH4 emission in vitro....

We propose an early warning model for predicting the likelihood of a financial stress event for a given future time, and examine whether credit plays an important role in the model as a non-linear propagator of shocks. This propagation takes the form of a threshold regression in which a regime change occurs if credit conditions cross a critical threshold. The in-sample and out-of-sample forecasting performances are encouraging. In particular, the out-of-sample forecasting results suggest that...

This paper measures market power in a decentralized market where contracts are determined through a search and negotiation process. The mortgage industry has many institutional features which suggest competitiveness: homogeneous contracts, negotiable rates, and, for a given consumer, common lending costs across lenders. As a result, even with a small number of lenders, informed borrowers can gather multiple quotes. However, there is important heterogeneity in the ability of consumers to understand the subtleties of financial...

The Lisbon Winter School for the Study of Communication is a response to two troubling conditions of the contemporary moment: Firstly, it recognizes that doctoral students researching the challenges posed by contemporary phenomena in media and communication need new fora to foster discussion in real time of ideas and theories that may help them grasp more fully rapidly changing realities. Secondly, it aims to facilitate global discussions at a time marked by political and cultural...
