The new version of the pictorial scale of Perceived Movement Skill Competence in Spanish children: Evidence of validity and reliability. [La nueva ve…

2019

The purpose of this study was to i) examine reliability and construct validity of the pictorial scale of Perceived Movement Skill Competence (PMSC) aligned to the third version of the Test of Gross Motor Development (TGMD-3) in a sample of Spanish children; and to ii) analyse the validity of the PMSC and children’s perceived motor competence (MC) according to gender. A convenience sample of 361 children (55.7% boys) between 4 and 11 years-old participated. The pictorial scale of PMSC (19 items) was administered (a random subsample repeated the PMSC twice). Test-retest reliability using Intraclass Correlation Coefficients and construct validity using a Bayesian Structural Equation Modeling a…

Reliable Correlational Cuing While Controlling for Most-Recent-Pairing Effects.

2020

Irrelevant aspects of the environment or irrelevant attributes of task-relevant stimuli can have important and reliable effects on behavior. When the specific values of an irrelevant stimulus attribute are correlated with different responses, a correlational-cuing effect is observed: faster and more accurate responses when the correlation is positive than when it is negative. Previous work has shown that this effect is not due to simple differences in how often the specific stimuli are being presented, and most explanations of the effect have stressed the clear parallels with classical associative learning. Very recently, however, evidence in favor of an alternative model has been presented…

Radzenes biezuma un acs refrakcijas korelācija bērniem.

2020

Maģistra darbs ir uzrakstīts 46 lappusēm angļu valodā. Tas satur 19 attēlus, 9 tabulas, un 62 informācijas avotus. Šī darba mērķis ir izpētīt korelāciju starp radzenes biezumu un acs refrakciju 5-12 gadus veciem bērniem. Radzenes biezuma kartes un keratometrija tika mērīta, izmantojot Scheimpflug attēl veidošanas sistēmu Schwind Sirius. Keratometrija un refrakcija tika mērīta, izmantojot autokeratorefraktotonometru Topcon TRK-2P cikloplēģijā. Katram parametram tika veikti trīs mērījumi turpmākai analīzei. Šī pētījuma nolūkos tika analizētas 196 acis. Dalībniekiem ar hipermetropiju un hipermetropo astigmātismu novēroja lielākas radzenes biezuma vērtības centrā un radzenes perifērijā, atšķirī…

Study of vegetation evolution in Sicily using time series analysis of remote sensing and climatic data.

2007

During last 10 years, several studies confirmed that drought phenomena are affecting southern Mediterranean areas. One of the effects of a persistent drought is a modification of the vegetation cover and biomass. The aim of our research is to investigate and monitor the evolution of this phenom- enon in Sicily using remote sensing techniques. To do this, a data set of NOAA-AVHRR multispectral images, acquired monthly from 1988 to 2005, has been calibrated and processed. A time series analysis (TSA) has been applied both on the NDVI and precipitation data sets in order to study the main characteristics of vegetation distribution during the period under investigation and to compare the vegeta…

Cell degradation detection based on an inter-cell approach

2017

Fault management is a crucial part of cellular network management systems. The status of the base stations is usually monitored by well-defined key performance indicators (KPIs). The approaches for cell degradation detection are based on either intra-cell or inter-cell analysis of the KPIs. In intra-cell analysis, KPI profiles are built based on their local history data whereas in inter-cell analysis, KPIs of one cell are compared with the corresponding KPIs of the other cells. In this work, we argue in favor of the inter-cell approach and apply a degradation detection method that is able to detect a sleeping cell that could be difficult to observe using traditional intra-cell methods. We d…

Modeling long-range memory with stationary Markovian processes

2009

In this paper we give explicit examples of power-law correlated stationary Markovian processes y(t) where the stationary pdf shows tails which are gaussian or exponential. These processes are obtained by simply performing a coordinate transformation of a specific power-law correlated additive process x(t), already known in the literature, whose pdf shows power-law tails 1/x^a. We give analytical and numerical evidence that although the new processes (i) are Markovian and (ii) have gaussian or exponential tails their autocorrelation function still shows a power-law decay =1/T^b where b grows with a with a law which is compatible with b=a/2-c, where c is a numerical constant. When a<2(1+c) th…

The effective cross section for double parton scattering within a holographic AdS/QCD approach

2017

A first attempt to apply the AdS/QCD framework for a bottom-up approach to the evaluation of the effective cross section for double parton scattering in proton-proton collisions is presented. The main goal is the analytic evaluation of the dependence of the effective cross section on the longitudinal momenta of the involved partons, obtained within the holographic Soft-Wall model. If measured in high-energy processes at hadron colliders, this momentum dependence could open a new window on 2-parton correlations in a proton.

Mean speed in professional cycling: No evidence of decline

2014

Abstract The aim of this article was to evaluate the mean speed progression of the three major cycling stage races in order to empirically establish whether excellent in performance in professional cycling is to some extent correlated with the trend of blood doping and anti-doping throughout more than a century of official cycling competitions. We retrieved data about the mean speed of the winners of the Tour de France, Giro d’Italia and Vuelta a Espana, since their beginning. A linear correlation has then been calculated between the years and the mean speed in km/h for each single major cycling stage race, as well as for the mean speed of the winners of the three major cycling stage races …
