Recent Developments in Absolute Shielding Scales for NMR Spectroscopy
(Elsevier Academic Press Inc, 2019-01)
The absolute value of the nuclear magnetic shielding tensor, σ, cannot be directly measured as such, though at the moment experimental devices are available to obtain them by extrapolation to zero-density limit. This is ...
Psychometric properties of the spanish version of the UPPS-P Impulsive Behavior Scale: A rasch rating scale analysis and confirmatory factor analysis
(American Psychological Association, 2015-08-17)
The present study was aimed at determining the psychometric properties of the Spanish version of the UPPS-P Impulsive Behavior Scale in a sample of college students. Participants were 318 college students (36.2% men; mean ...
Modelling carbon and water balance of Eucalyptus plantations at regional scale: Effect of climate, soil and genotypes
(2019-10-01)
Carbon and water budgets of forest plantations are spatially and temporally variable and hardly empirically predictable. We applied G'DAY, a process-based ecophysiological model, to simulate carbon and water budgets and ...
Advantages of the Rasch Model for Analysis and Interpretation of Attitudes: the Case of the Benevolent Sexism Subscale
(2018)
This paper describes how the use of Rasch Analysis (RA), compared with the Classical Test Theory (CTT) and other Item Response Theory (IRT) approaches, could enhance the study and interpretation
of attitudinal scales. ...

Root proliferation strategies and exploration of soil patchiness in arid communities
(Wiley Blackwell Publishing, Inc, 2017-11)
Soil patchiness is a key feature of arid rangelands. As root proliferation contributes to soil exploration and resource uptake, it is ecologically relevant to understand how species respond to soil heterogeneity and coexist. ...
Topside ionospheric effective scale heights (HT) derived with ROCSAT‐1 and ground‐based ionosonde observations at equatorial and midlatitude stations
(American Geophysical Union, 2009-10-16)
In this study we propose the assimilation of topside in situ electron density data from the Republic of China Satellite (ROCSAT‐1) along with the ionosonde measurements for accurate determination of topside ionospheric ...
Is It Possible to Measure the Role of the Bystander and the Victim of Bullying in Children? Construct Validity of Two Brief Pictorial Scales With IRT and CFA Models
(SAGE PublicationsUS, 2021-08-02)
ABSTRACT
The study's objective was to develop and validate the psychometric properties of two brief pictorial scales to evaluate the roles of bystanders and victims of bullying. A sample of 910 students was considered ...
Experimental verification for a scaling law relating amplitude and frequency in the complex susceptibility of type-II superconductors
