Peer Tutoring Effects on Students’ Mathematics Anxiety: A Middle School Experience

open access: yesFrontiers in Psychology, 2020
In this research the effects of reciprocal peer tutoring on students’ mathematics anxiety levels were examined. A pretest posttest with control group design was used at a public middle school in Spain.

Beam-size effect in Bremsstrahlung

open access: yes, 2003
The smallness of the transverse dimensions of the colliding beams leads to suppression of bremsstrahlung cross section. This beam-size effect was discovered and investigated at INP, Novosibirsk. Different mechanisms of radiation are discussed. Separation

Finite-Size Effect of Hadron Masses with Kogut-Susskind Quarks [PDF]

open access: yes, 1993
We present numerical results and their analyses of finite-size effects of hadron masses for both quenched and full QCD calculations. We show that they are much larger for full QCD due to dynamical sea quarks and the associated breaking of $Z(3)$ symmetry.

Does nature-based social prescription improve mental health outcomes? A systematic review and meta-analysis

open access: yesFrontiers in Public Health
BackgroundA nature-based social prescription (NBSP) is an approach to improving mental health outcomes that involves prescribing nature-based interventions as complementary or alternative therapy to traditional ones. A variety of advantages are available

One-Way and Two-Way ANOVA: Inferences About a Robust, Heteroscedastic Measure of Effect Size

open access: yesMethodology, 2022
Consider a one-way or two-way ANOVA design. Typically, groups are compared based on some measure of location. The paper suggests alternative methods where measures of location are replaced by a robust measure of effect size that is based in part on a ...

Effect of size on cracking of materials [PDF]

open access: yes, 1971
Brittle behavior of large mild steel elements, glass plasticity, and fatigue specimen size sensitivity are manifestations of strain-energy size effect. Specimens physical size effect on material cracking initiation occurs according to flaw distribution ...

Impact of Size Effect on Graphene Nanoribbon Transport

open access: yes, 2010
Graphene has shown impressive properties for nanoelectronics applications including a high mobility and a width-dependent bandgap. Use of graphene in nanoelectronics would most likey be in the form of graphene nanoribbons (GNRs) where the ribbon width is

MOOD SWINGS AND THE FIRM SIZE PREMIUM [PDF]

open access: yesOradea Journal of Business and Economics
Evidence accumulated in the literature indicates that the size effect is related to corporate and macroeconomic variables and is paid to compensate for bearing risk. We show that the size premium is also driven by daily variations in investors’ moods. We

Quantum Size Effect transition in percolating nanocomposite films

open access: yes, 2000
We report on unique electronic properties in Fe-SiO2 nanocomposite thin films in the vicinity of the percolation threshold. The electronic transport is dominated by quantum corrections to the metallic conduction of the Infinite Cluster (IC).

Accounting for baseline trends in intervention studies: Methods, effect sizes, and software

open access: yesCogent Psychology, 2019
Single-case experimental studies are relevant and important to substantiate the effectiveness of behavioral, clinical, and educational interventions. When a baseline trend is present in intervention studies, it is challenging for researchers to determine,
