Time spent on the smartphone does not relate to manual dexterity in young adults.
2021
Abstract Background The Grooved Pegboard Test (GPT) is widely adopted to evaluate manual dexterity, it presents normative data but the test is influenced by different factors. The influence of time spent on smartphones has not been considered before, for this reason, the objective of this study was to evaluate if smartphone use influences the time to complete the GPT. A total of 38 (21 women; 17 men) young adults 20.7 (1.5) years participated in the study. The time spent on the smartphones during the last seven days was recorded through the device itself and the GPT performance was measured. A correlation analysis between the time spent on the smartphone and GPT was performed while the t-te…
The “Journal of Functional Morphology and Kinesiology” Journal Club Series: Highlights of Recent Papers in Pediatric Exercise
2019
We are glad to introduce the ninth Journal Club. This edition is focused on several relevant studies published in the last years in the field of Pediatric Exercise, chosen by our Editorial Board members and their colleagues. We hope to stimulate your curiosity in this field and to share with you the passion for the sport as seen also from the scientific point of view. The Editorial Board members wish you an inspiring lecture.
Development of the Optical Multiplexer Board Prototype for Data Acquisition in the TileCal System
2006
This paper describes the development of the optical multiplexer board (OMB), also known as PreROD board, for the TileCal readout system in the ATLAS experiment. The aim of this board is to overcome the problems that may arise in the integrity of data due to radiation effects. The solution adopted has been to add redundancy to data transmission and so two optical fibers with the same data come out from the detector front end boards. The OMB has to decide in real time which fiber, eventually, carries data with no errors switching it to the output link connected to the read out driver (ROD) motherboard where data processing takes place. Besides, the board may be also used as a data injector fo…
A Portable Readout System for Microstrip Silicon Sensors (ALIBAVA)
2009
A readout system for microstrip silicon sensors has been developed. This system is able to measure the collected charge in one or two microstrip silicon sensors by reading out all the channels of the sensor(s), up to 256. The system can operate either with non-irradiated and irradiated sensors as well as with n-type and p-type microstrip silicon sensors. Heavily irradiated sensors will be used at the Super Large Hadron Collider, so this system can be used to research the performance of microstrip silicon sensors in conditions as similar as possible to the Super Large Hadron Collider operating conditions. The system has two main parts: a hardware part and a software part. The hardware part a…
From the Reference SEU Monitor to the Technology Demonstration Module On-Board PROBA-II
2008
The reference SEU Monitor system designed and presented in 2005 (R. H. SOslashrensen, F.-X. Guerre, and A. Roseng ldquoDesign, testing and calibration of a reference SEU monitor system,rdquo in Proc. RADECS, 2005, pp. B3-1-B3-7) has now been used by many researchers at many radiation test sites and has provided valuable calibration data in support of numerous projects. As some of these findings and results give new insight into improved inter-facility calibrations and provide additional inputs into ongoing SEE research, a few of the more interesting cases are presented. Furthermore the dasiadetector elementpsila, the Atmel AT60142F SRAM, now in a hybrid configuration, will form the key dete…
Maximum and Actual Evapotranspiration for Barley (Hordeum vulgare L.) through NOAA Satellite Images in Castilla-La Mancha, Spain
1996
Abstract An easy-to-follow methodology is developed for the assessment of regional evapotranspiration in Castilla-La Mancha, a semi-arid region of Spain. The methodology is applied to barley crops to monitor the irrigation scheduling over the region, by using remote sensing techniques supplemented by ground measurements. The methodology can be based on either of two models. In the first one, established by Caselles and Delegido, 1 the reference evapotranspiration, ET o , derives from the expression ET o = AR g (T a ) m a x + BR g + C where A, B and C are empirical coefficients, depending on climatic parameters and determined for each region; R g is the daily global radiation; and ( T a ) m …
Determinants of Board Size, Composition and Leadership
2018
Using a 14-year panel data set on the Standard and Poor’s 1500 firms, this chapter examines the trends and determinants of corporate board structure (Board size, independence and CEO duality). Our hypotheses lead to predictions that firm complexity and advising requirements, the costs of monitoring and advising, ownership structure and CEO characteristics are important determinants of board structure. Our findings provide strong empirical evidence in support of these hypotheses. We also find some evidence that the Sarbanes–Oxley Act has had an impact on board structure and its determinants.
Rotor—frame contact in a centrifuge installed on board a ship
2009
The criticality of rotor and stator contact in a large-size marine separator is studied by numerical modelling. Two plausible mechanisms leading to such contact, namely rolling of a ship in steady-state motion and a suddenly occurring unbalance in the rotor, are considered. It is found that contact due to sea motion may be tolerable, while sudden development of unbalance at operating speed can lead to unacceptably high contact forces. This agrees with experience of centrifugal separators operating on board of ships.
Changing the Corporate Elite? Not so Easy: Female Directorss Appointments Onto Corporate Boards
2013
Scholars have previously investigated country and organizational-level factors associated with the incidence of female directors on boards. These studies, however, cannot explain why, in countries with strong gender equality and pressure for female directorships, firms are still hesitant to promote new women to their boards. To address this issue we – in this study – introduce the cognitive and affective processes related to directors’ identification with the traditional corporate elite as an explanation for the slow organizational response to pressure for gender diversity on boards. We bridge the social identity and critical mass theory to further show how these responses may vary with the…
On Board the Nautilus
2012
Some months ago, I took part, with some friends, in an astronomy trip to the mountain Pico del Buitre, in Javalambre (province of Teruel, Spain). The trip, among whose participants there were prospective scientists between the age of four and nine, included a night devoted to amateur observation with portable telescopes. El Pico del Buitre is one of the darkest spots in Spain—and also one of the coldest, as all members of the party remember well. Even darker is Roque de los Muchachos, on Las Palmas (Gran Canaria, Canary Islands), one of the most important sites for astronomy observation on the Northern hemisphere.
