- A Near-Real-Time Operational Live Fuel Moisture Content (LFMC) Product to Support Decision-Making at the National LevelPublication . Benali, Akli; Baldassarre, Giuseppe; Loureiro, Carlos; Briquemont, Florian; Fernandes, Paulo M.; Rossa, Carlos; Figueira, RuiLive fuel moisture content (LFMC) significantly influences fire activity and behavior over different spatial and temporal scales. The ability to estimate LFMC is important to improve our capability to predict when and where large wildfires may occur. Currently, there is a gap in providing reliable near-real-time LFMC estimates which can contribute to better operational decision-making. The objective of this work was to develop near-real-time LFMC estimates for operational purposes in Portugal. We modelled LFMC using Random Forests for Portugal using a large set of potential predictor variables. We validated the model and analyzed the relationships between estimated LFMC and both fire size and behavior. The model predicted LFMC with an R2 of 0.78 and an RMSE of 12.82%, and combined six variables: drought code, day-of-year and satellite vegetation indices. The model predicted well the temporal LFMC variability across most of the sampling sites. A clear relationship between LFMC and fire size was observed: 98% of the wildfires larger than 500 ha occurred with LFMC lower than 100%. Further analysis showed that 90% of these wildfires occurred for dead and live fuel moisture content lower than 10% and 100%, respectively. Fast-spreading wildfires were coincident with lower LFMC conditions: 92% of fires with rate of spread larger than 1000 m/h occurred with LFMC lower than 100%. The availability of spatial and temporal LFMC information for Portugal will be relevant for better fire management decision-making and will allow a better understanding of the drivers of large wildfires.

- Use and Acquisition of Communicative Functions and Communicative Forms by Portuguese European Toddlers with and without Hearing ImpairmentPublication . Lima, Etelvina; Cruz-Santos, AnabelaPurpose: The purpose of this study was to identify and compare communicative functions and forms in toddlers without (age group 8 to 18 months) and with hearing impairment (age group 13 to 18 months).Methods: Participants were 37 toddlers with normal hearing, 4 toddlers with hearing impairment.Results: The results indicate an increase in the average of the communicative functions conveyed along the increase of the age groups. There is an association between the age group and the type of communicative functions taught. Although there is no relationship between the hearing impairment condition and the average use of communicative functions, the two groups make different use of the type of communicative functions as well as the communicative forms.Conclusion: Is of paramount importance to understand the relationships between communicative forms and communicative functions in the assessment and intervention of communication skills in toddlers. In the case of toddlers with hearing impairment is fundamental to be aware that is not the frequency but the type of communication skills that they establish with their interlocutors.
