L-Band vegetation optical depth for crop phenology monitoring and crop yield assessment
2018
Vegetation Optical Depth (VOD) at L-band is highly sensitive to the water content and above-ground biomass of vegetation. Hence, it has great potential for monitoring crop phenology and for providing crop yield forecasts. Recently, the Multi-Temporal Dual Channel Algorithm (MT -DCA) has been proposed to retrieve L-band VOD from Soil Moisture Active Passive (SMAP) measurements. In previous research, SMAP VOD has been compared to crop phenology and has been used to derive crop yield estimates. Here, we review and expand these initial research studies. In particular, we quantify the capability of VOD to detect different crop stages, and test different VOD metrics (i.e., maximum, range and inte…
The value of local climate and weather information: an economic valuation of the decentralised meteorological provision in Kenya
2020
The development of Sub-Saharan Africa will become increasingly constrained by the acute climate sensitivity of livelihood practices. Weather and climate services can improve climate risks to development by informing plans and decisions that ultimately reduce losses/maximize beneficial opportunities from climate variability and change. Yet, such services are typically highly aggregated, and notoriously difficult to communicate, especially to smallholder farmers and pastoralists where the need is greatest. Kenya Meteorological Department (KMD) are decentralizing service provision, and in so doing, offering disaggregated, contextualized, and more easily understandable localized weather and sea…
Association between climate and new daily diagnoses of COVID-19
2020
AbstractBackgroundAlthough evidence is accumulating that climate conditions may positively or negatively influence the scale of coronavirus disease 2019 (COVID-19) outbreaks, uncertainty remains concerning the real impact of climate factors on viral transmission. Methods. The number of new daily cases of COVID-19 diagnosed in Verona (Italy) was retrieved from the official website of Veneto Region, while information on daily weather parameters in the same area was downloaded from IlMeteo website, a renowned Italian technological company specialized in weather forecasts. The search period ranged between March 1 to November 11, 2020. The number of new daily COVID-19 cases and meteorological da…
Two Borderline Works: The Miniature Classical Friezes by John Henning
2020
The plaster replicas of two miniaturized reproductions of the Parthenon and Bassae friezes are preserved at the Plaster Cast Gallery of the Department Cultures and Societies of the University of Palermo. The original reproductions were made by the Scottish carver John Henning in the first decades of the 19th century. These artefacts, although they have seldom captured the attention of the archaeologists, are of particular interest and from manifold points of view.
La Gipsoteca del Dipartimento Culture e Società dell'Università degli Studi di Palermo. Storia e catalogo
2017
Il volume presenta, per la prima volta, la storia e il catalogo della Gipsoteca del Dipartimento Culture e Società dell’Università degli Studi di Palermo. Si tratta di un’importante raccolta di calchi in gesso di sculture antiche, voluta da Antonino Salinas (1841-1914) ai tempi del suo magistero accademico e ora completamente riordinata, grazie a un nuovo allestimento curato dallo stesso autore di questo libro. The volume presents, for the first time, the history and catalog of the Gipsoteca of the Culture and Society Department of the University of Palermo. This is an important collection of plaster casts of ancient sculptures, commissioned by Antonino Salinas (1841-1914) at the time of hi…
Inflation anchoring and growth: The role of credit constraints
2022
Abstract Can inflation anchoring foster growth? To answer this question, we use panel data on sectoral growth for 22 manufacturing industries from 39 advanced and emerging market economies over 1990–2014 and employ a difference-in-differences strategy based on the theoretical prediction that higher inflation uncertainty particularly depresses investment in industries that are more credit constrained. Industries characterized by high external financial dependence, liquidity needs, and R&D intensity, and low asset tangibility, tend to grow faster in countries with well-anchored inflation expectations. The results, based on an IV approach—using indicators of monetary policy transparency and ce…
« Dans le goût de l’antique »
2021
L’interet pour le patrimoine universitaire des universites de Besancon et de Dijon nous a recemment conduits a entreprendre un programme de recherche sur le patrimoine pedagogique lie a l’enseignement de l’histoire de l’art et de l’archeologie a l’echelle de notre region Bourgogne - Franche-Comte (voir ici : https://ista.univ-fcomte.fr/projet-scientifique/projet-moulages). Dans l’etude des photographies argentiques diffusees par les maisons parisiennes (telle Giraudon), des plaques photographiques, des ouvrages de litterature specialisee acquis par nos bibliotheques et des collections de moulages en plâtre constituees a la fin du xixe siecle, nous avons mis en relation les collections des e…
Encuestas a pie de urna en España. ¿Error muestral o sesgo de no respuesta?
2016
Countless examples of misleading forecasts on behalf of both pre-election and exit polls can be found all over the world. Non-representative samples due to differential nonresponse have been claimed as being the main reason for inaccurate exit-poll projections. In real inference problems, it is seldom possible to compare estimates and true values. Electoral forecasts are an exception. Comparisons between estimates and final outcomes can be carried out once votes have been tallied. In this paper, we examine the raw data collected in seven exit polls conducted in Spain and test the likelihood that the data collected in each sampled voting location can be considered as a random sample of actua…
Performance of DEMETER calibration for rainfall forecasting purposes: Application to the July–August Sahelian rainfall
2008
International audience; This work assesses and compares the skill of direct and model-output-statistics (MOS) calibrated hindcasts of the July–August rainfall amounts for the dry period 1980–2000 over the Sahel issued from the Development of a European Multimodel Ensemble System for Seasonal to Interannual Prediction (DEMETER) experiment, with the aim to highlight among the simulated parameters, i.e., those potentially relevant for rainfall forecasts purposes. Three approaches were used: the DEMETER (1) direct rainfall, (2) MOS-calibrated rainfall, and (3) MOS-calibrated atmospheric dynamics and energy. Canonical correlation analyses (CCA) were employed in the two latter approaches to calib…
Peek polymer in orthodontics : a pilot study on children
2017
The purpose of the study has been making the orthodontic space maintainers in PEEK polymer (Polyetheretherketone) through a digital workflow. New digital technologies are taking hold in diagnosis, therapy and in dental laboratories. The digital world can help dentist in diagnosis and therapy: -diagnosis through the acquisition of radiographic images (CBCT) or scanners which allow the creation of 3D digital models - about therapy thanks to dental CAD CAM system. It consists of design devices through an dedicated software CAD and then realize devices through CAM system. We used digital system to improve the quality of the treatment and reduce costs. Peek polymer, subject of studies in recent …
