Does board diversity affect firm performance? Evidence from the Italian Financial Sector
2017
The aim of the study is to examine the effect of diversity in the board of directors on the performance of the listed Italian financial institutions. The sample is a data set of 177 firm-year observations covering 2011 to 2014. The performance of the firm is measured by Tobin’s Q while board diversity is analysed considering the percentage of female and foreign directors on the board (or their conjoint presence as a proxy of overall demographic diversity) and task-diversity is measured by board interlocking directorship and busy directors. Findings suggest that female directors have no effect on firm performance. Foreign directors and interlocking directorship have, instead, a positive stat…
Thermal infrared radiance model for interpreting the directional radiometric temperature of a vegetative surface
1990
Abstract In this work we have proposed a two-dimensional radiance model that serves for interpreting the directional remotely-sensed thermal infrared data obtained over a vegetative surface when the effects of the shadows are minimal. The model was validated for different view angles from the measurements made with a radiometer placed on board a helicopter in two different citrus regions. And the root-mean-square deviation between the model predictions and the sensor measurements was 0.3°C.
EUIPO Boards of Appeal in the Light of the Principle of Fair Trial
2022
The EUIPO’s Boards of Appeal are called upon to decide on appeals against decisions by the bodies of ‘first instance’. However, their judicial function has always been denied. Conversely, the essay tends to place the Boards of Appeal of the EUIPO in any case within the concept of ‘court’, as defined by the ECtHR, within the framework of Article 6 ECtHR, because it assesses their independence, impartiality, and in general the guarantees required by the ‘fair trial’, until concluding that it is a paradigmatic model in the overall administration and judicial system. EUIPO Boards of Appeal, European Court of Human Rights, Court of Justice of the Eurpean Union, EU Charter of Fundamental Rights, …
The effect of writing modality on recollection in children and adolescents
2019
We set out to assess the extent to which writing modality affects recollection in children and adolescents. We examined 10- to 11-year-old children’s (N = 63) and 16-year-old adolescents’ (N = 43) handwriting, keyboarding with a laptop computer and keyboarding with a touchscreen tablet computer or mobile phone in a within-subjects experimental design. Participants were instructed to write down stories dictated to them in the three writing modalities. Recollection of the stories was assessed using free recall of details in the stories. The results indicate that the writing modality affects recollection, handwriting leading to better recollection. However, currently, digital writing tools are…
Induced hyperactivity in boar spermatozoa and its evaluation by computer-assisted sperm analysis.
2004
Hyperactivity, a form of sperm motility characterized by vigorous flagellar movements, has been proposed as essential for fertilization in mammals. The objective of the present study was to establish a method for inducing hyperactivityin vitroin boar spermatozoa and to define threshold values to differentiate between hyperactive and non-hyperactive spermatozoa by computer-assisted sperm analysis (CASA) as a prerequisite for analyzing the energy metabolism during hyperactivity. In TALP-HEPES medium, non-frozen boar spermatozoa were stimulated to hyperactivity by 50 μmol l−1Ca2+within 15 min at 37 °C if 5 μmol l−1of the Ca2+ionophore A23187 was present. If 25% seminal plasma was present, boar…
Statistical issues in the development of an automotive on-board diagnostics
2008
The automotive on-board diagnostics (OBD) is a complex system whose aim is to monitor the state-of-health of another complex system, i.e. the vehicle engine. OBD aimed at the containment of polluting exhaust emissions is nowadays compulsory on every vehicle model introduced into the market. Increasingly stringent regulations and ever more demanding customers push from opposite sides towards a perfect working of OBD systems. Therefore manufacturers are globally interested in the high robustness and reliability of such critical systems. The aim of this presentation is to give an insight into the main statistical problems arisen during an extensive research project carried out in collaboration…
High-definition transcranial direct current stimulation to both primary motor cortices improves unimanual and bimanual dexterity.
2017
While most research on brain stimulation with transcranial direct current stimulation (tDCS) targets unimanual motor tasks, little is known about its effects on bimanual motor performance. This study aims to investigate the effects of tDCS on unimanual as well as bimanual motor dexterity. We examined the effects of bihemispheric anodal high-definition tDCS (HD-atDCS) on both primary motor cortices (M1) applied concurrent with unimanual and bimanual motor training. We then measured the effects with the Purdue Pegboard Test (PPT) and compared them to a sham stimulation. Between a pretest and posttest, 31 healthy, right-handed participants practiced the PPT on three consecutive days and receiv…
Muestreos utilizados en investigación educativa en España
2002
En este trabajo se expone un estudio bibliográfico de distintas investigaciones que se han publicado recientemente en España, en las actas de congresos sobre educación. De todas las investigaciones que se han revisado, se analiza el tipo de muestreo que han empleado, cómo han sido seleccionadas y la aplicación de los instrumentos para la recogida de información, así como la forma en que han sido recogidos esos datos. Se pretende resaltar la importancia de la selección de muestras representativas, sobre todo para que los resultados tengan mayor relevancia y repercusión en el desarrollo del conocimiento educativo.
Ultrascale+ for the new ATLAS calorimeter trigger board dedicated to jet identification
2018
To cope with the expected increase in luminosity at the Large Hadron Collider in 2021, the ATLAS collaboration is planning a major detector upgrade to be installed during Long Shutdown 2. As a part of this, the Level 1 trigger, based on calorimeter data, will be upgraded to exploit the fine granularity readout using a new system of Feature EXtractors (FEXs), which each reconstruct different physics objects for the trigger selection. The Jet FEX (jFEX) is one of three FEXs and has been conceived to identify small/large area jets, large area tau leptons, missing transverse energy and the total sum of the transverse energy. The use of the latest generation Xilinx Field Programmable Gate Array …
The intensity contrast of solar photospheric faculae and network elements : II. Evolution over the rising phase of solar cycle 23
2006
We studied the radiative properties of small magnetic elements (active region faculae and the network) during the rising phase of solar cycle 23 from 1996 to 2001, determining their contrasts as a function of heliocentric angle, magnetogram signal, and the solar cycle phase. We combined near-simultaneous full disk images of the line-of-sight magnetic field and photospheric continuum intensity provided by the MDI instrument on board the SOHO spacecraft. Sorting the magnetogram signal into different ranges allowed us to distinguish between the contrast of different magnetic structures. We find that the contrast center-to-limb variation (CLV) of these small magnetic elements is independent of …
