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…
Información política televisiva y espectacularización : un análisis comparativo de programas informativos y de infoentretenimiento
2014
Este artículo estudia la tendencia a la espectacularización en el tratamiento de la información política televisiva en España. Realizamos un estudio de espacios informativos, así como una comparación de los anteriores con los contenidos de programas de infoentretenimiento (infotainment). El análisis de los informativos se centra en los canales autonómicos Canal Sur y Canal 9RTVV, mientras que la muestra de infotainment abarca diez programas procedentes de cadenas tanto privadas como públicas.A partir de un análisis de contenido temático, los resultados indican similitudes entre los informativos y el infotainment en lo relativo a la espectacularización, siendo la personalización el indicador…
Does the interaction between the accounting method choice and disclosure affect financial analysts’ information environment? The case of joint ventur…
2017
IAS 31 allowed firms to choose between proportionate consolidation and the equity method to record joint ventures in the consolidated accounts of the venturer. Moreover, this election implied a decision about including information in the primary financial statements or in the notes. This paper investigates if financial analysts perceive accounting information differently depending on the method chosen conditioned to the disclosure of the required information in the notes. We analysed a sample of Spanish firms during 2005–2010. We not only considered earnings forecasts, but also examined target prices and stock recommendations. Furthemore, we look at how this accounting choice affects analys…
Orthopedic versus surgical treatment of Gartland type II supracondylar humerus fracture in children.
2013
The choice of orthopedic or surgical treatment for Gartland type II supracondylar humeral fractures remains controversial. The aim of this study was to retrospectively compare the outcomes in orthopedic and surgical treatment in type II supracondylar humeral fractures in children treated in the Orthopedic and Traumatology Children Unit of our tertiary hospital over the period between 2007 and 2010. This study suggests that orthopedic treatment is a valid option for the treatment of this type of fractures, with radiological and functional results as good as those obtained with surgical treatment, avoiding surgical complications and decreasing the hospital stay.
Identification and Handling of Critical Irradiance Forecast Errors Using a Random Forest Scheme – A Case Study for Southern Brazil
2015
Abstract Large forecast errors of solar power prediction cause challenges for the management of electric grids. Here, the classification technique Random Forests is applied to analyze the possible linkage of hourly or daily forecast errors to the actual situation given by a set of meteorological variables. This form a prediction of the forecast error and is thus usable to update the forecast. The performance of this scheme is assessed for the example of irradiance forecasts in Brazil. While limited to none improvements are obtained for next-hour forecasts, significant improvements are obtained for the next-day forecasts.
Utilization of microbial abundance and diversity as indicators of the origin of soil aggregates produced by earthworms
2013
This study aimed at testing the capability of microbial community structure and abundance to be used as bioindicators of the origin of earthworm cast aggregates. Compact surface casts produced by Amynthas khami and surrounding aggregates lacking visible signs of biological activity (control) were left to disaggregate by natural rainfall and separated into four size classes (5-2, 2-0.5, 0.5-0.25 and <0.25 mm). The genetic structure and the abundance of the bacterial and fungal communities were characterized using B- and F-ARISA fingerprinting approach and quantitative PCR directly from DNA extracted from soil. Bacteria and to a lesser extent fungi were more abundant in casts than in control …
A comparison between dental measurements taken from CBCT models and those taken from a digital method.
2011
The aims of the study were to assess speed, reliability, accuracy, and reproducibility in measuring mesiodistal tooth sizes, bicanine widths, bimolar widths, and arch lengths (ALs) using cone beam computed tomography (CBCT) and to compare them with the same measurements obtained using a two-dimensional (2D) Digital Method. Plaster study models were made for 27 patients and then digitalized and measured using a 2D Digital Method. CBCTs were undertaken on the same 27 patients using the Dental Picasso Master 3D® and the images obtained were then analysed using the InVivoDental program. The correlation study of the two measuring methods, which were compared by determining the regression paramet…
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…
Visitor arrivals forecasts amid COVID-19: A perspective from the Africa team
2021
Abstract COVID-19 disrupted international tourism worldwide, subsequently presenting forecasters with a challenging conundrum. In this competition, we predict international arrivals for 20 destinations in two phases: (i) Ex post forecasts pre-COVID; (ii) Ex ante forecasts during and after the pandemic up to end 2021. Our results show that univariate combined with cross-sectional hierarchical forecasting techniques (THieF-ETS) outperform multivariate models pre-COVID. Scenarios were developed based on judgemental adjustment of the THieF-ETS baseline forecasts. Analysts provided a regional view on the most likely path to normal, based on country-specific regulations, macroeconomic conditions,…
Combining a data-driven approach with seasonal forecast data to predict reservoir water volume in the Mediterranean area
2023
Prolonged droughts and water scarcity have become more frequent in recent years, exacerbating the problem of the artificial reservoirs management in the Mediterranean area. This study proposes a methodology which combines a Nonlinear AutoRegressive network with eXogenous input (NARX) data-driven model with Seasonal Forecasts (SFs) data, with the aim to predict the water volume stored in reservoirs at a mid-term scale, as requested by the local authority. The methodology is applied to four Sicilian reservoirs that experienced water scarcity in the recent past. SFs produced at the European Centre for Medium-Range Weather Forecasting are used to force the NARX models. Also, the reservoirs are …
