Methodological Quality Assessment with the AGREE II Scale and a Comparison of European and American Guidelines for the Treatment of Lyme Borreliosis: A Systematic Review [PDF]

open access: yesPathogens, 2021
Background: Most European and American countries recently updated their guidelines on Lyme borreliosis (LB). The aim of this study was to provide a comparative overview of existing guidelines on the treatment of LB in Europe and America and to assess the methodological quality of their elaboration.

Supernova Inelastic Neutrino-Nucleus Cross Sections from High-Resolution Electron Scattering Experiments and Shell-Model Calculations [PDF]

open access: yes, 2004
Highly precise data on the magnetic dipole strength distributions from the Darmstadt electron linear accelerator for the nuclei 50Ti, 52Cr and 54Fe are dominated by isovector Gamow-Teller-like contributions and can therefore be translated into inelastic ...

Bias and Changes in Perceived Intensity of Verbal Qualifiers Effected by Scale Orientation

open access: yesSurvey Research Methods, 2007
The objective of this study is to examine whether manipulating the orientation of a rating scale impacts on the perceived intensity of the verbal qualifiers.

A Unidimensional Item Response Model for Unfolding Responses From a Graded Disagree-Agree Response Scale [PDF]

open access: yesApplied Psychological Measurement, 1996
Binary or graded disagree-agree responses to atti tude items are often collected for the purpose of attitude measurement. Although such data are sometimes ana lyzed with cumulative measurement models, recent studies suggest that unfolding models are more appro priate (Roberts, 1995; van Schuur & Kiers, 1994).

How to agree on what is fundamental to optimal teamwork performance in a situation of postpartum hemorrhage? A multidisciplinary Delphi French study to develop the Obstetric Team Performance Assessment Scale (OTPA Scale)

open access: yesEuropean Journal of Obstetrics & Gynecology and Reproductive Biology, 2021
The objective of this study was to develop a new interdisciplinary teamwork scale, the Obstetric Team Performance Assessment (OTPA), for the management of the post-partum hemorrhage, through consensus agreement of obstetric caregivers. The goal is to provide a reliable tool for teaching and evaluating teams in high-fidelity simulation.This prospective ...

Dirac eigenvalue correlations in quenched QCD at finite density [PDF]

open access: yes, 2005
We compare eigenvalue correlations of the Dirac operator with a chemical potential obtained from lattice simulations of quenched QCD with analytic predictions obtained from chiral effective theories in the zero-momentum limit.

General allometric scaling of net primary production agrees with plant adaptive strategy theory and has tipping points [PDF]

open access: yesJournal of Ecology, 2017
SummaryAllometric scaling of net primary production (NPP) with plant biomass (B) is important to ecological carbon dynamics and energetics. Metabolic theory predicts a nonlinear power law forNPPscaling, based on fractal vascular systems, resulting in a linear model when using logNPP/log B axes that are standard in allometry.

Comparing the QCD potential in Perturbative QCD and Lattice QCD at large distances [PDF]

open access: yes, 2002
We compare the perturbatively calculated QCD potential to that obtained from lattice calculations in the theory without light quark flavours. We examine E_tot(r) = 2 m_pole + V_QCD(r) by re-expressing it in the MSbar mass m = m^MSbar(m^MSbar) and by ...

Agree or Disagree: Does It Matter Which Comes First? An Examination of Scale Direction Effects in a Multi-device Online Survey

open access: yesField Methods, 2021
Previous research shows that the direction of rating scales can influence participants’ response behavior. Studies also suggest that the device used to complete online surveys might affect the susceptibility to these effects due to the different question layouts (e.g., horizontal grids vs. vertical individual questions).

Social Risks and Development Gaps in Iraq: A Social Study in the City of Baghdad

open access: yesمجلة كلية التربية للبنات, 2022
Social risks posed a great challenge to the development path in Iraq, which resulted in widening the development gaps, whether these gaps were between rural and embargoed areas, or between Iraqi governorates, and the gender gap.
