title: Financial Literacy Meta-analysis - Extracted Data (Final).pdf

description: This dataset accompanies the meta-analysis titled <i>"What Actually Works? A Meta-Analysis of Financial Literacy Interventions Across Age Groups and Delivery Methods."</i> It contains coded data from 12 high-rigor quantitative studies evaluating financial literacy programs for youth aged 10 to 24. Variables include study identifiers, sample sizes, age group, delivery method, intervention type, instructional intensity, follow-up timing, outcome domain (knowledge, behavior, attitudes), effect sizes (Hedges’ g), and moderator codes. The dataset was used to calculate pooled effect sizes and conduct moderator analysis using a random-effects model.<br>

title: "Table 2" of "Rapidity and species dependence of particle production at large transverse momentum for d + Au collisions at s(NN)**(1/2) = 200-GeV."

description: High transverse-momentum rapidity asymmetry factor ($Y_{\scriptsize{\mbox{Asym}}}$) for $\pi^{+}+\pi^{-}$ and $p+\bar{p}$ for $|y| &lt; 0.5$ and $0.5 &lt; |y| &lt; 1.0$ for minimum bias $d+Au$ collisions at $\sqrt{s_{NN}}=200$ GeV. For comparison the inclusive charged hadron results from STAR [5] are also shown by the curves.
description: We determine rapidity asymmetry in the production of charged pions, protons, and antiprotons for large transverse momentum ($p_{T}$) for $d+Au$ collisions at $\sqrt{s_{NN}}=200$ GeV. The rapidity asymmetry is defined as the ratio of particle yields at backward rapidity ($Au$ beam direction) to those at forward rapidity ($d$ beam direction). The identified hadrons are measured in the rapidity regions $|y| &lt; 0.5$ and $0.5 &lt; |y| &lt; 1.0$ for the $p_{T}$ range $2.5 &lt; p_{T} &lt; 10$ GeV/c. We observe significant rapidity asymmetry for charged pion and proton + antiproton production in both the rapidity regions. The asymmetry is larger for $0.5 &lt; |y| &lt; 1.0$ than for $|y| &lt; 0.5$ and is almost independent of particle type. The measurements are compared to various model predictions employing multiple scattering, energy loss, nuclear shadowing, saturation effects, and recombination and also to a phenomenological parton model. We find that asymmetries are sensitive to model parameters and show model preference. The rapidity dependence of $\pi^{-} / \pi^{+}$ and $\bar{p} / p$ ratios in peripheral $d+Au$ and forward neutron-tagged events are used to study the contributions of valence quarks and gluons to particle production at high $p_{T}$.

description: The spin-density matrix elements $\rho_{00}$ with respect to the reaction plane in midcentral $Au+Au$ collisions at $\sqrt{s_{NN}}=200$ GeV versus $p_{T}$ of the vector meson. The sizes of the statistical uncertainties are indicated by error bars, and the systematic uncertainties by caps. The $K^{∗0}$ data points have been shifted slightly in $p_{T}$ for clarity. The dashed horizontal line indicates the unpolarized expectation $\rho_{00}=1/3$. The bands and continuous horizontal lines show predictions discussed in the text.
description: We present the first spin alignment measurements for the $K^{*0}(892)$ and $\phi(1020)$ vector mesons produced at midrapidity with transverse momenta up to 5 GeV/$c$ at $\sqrt{s_{NN}}=200$ GeV at RHIC. The diagonal spin-density matrix elements with respect to the reaction plane in $Au+Au$ collisions are $\rho_{00}=0.32 \pm 0.04 (\mbox{stat}) \pm 0.09 (\mbox{sys})$ for the $K^{*0}$ ($0.8 &lt; p_{T} &lt; 5.0$ GeV/$c$) and $\rho_{00}=0.34 \pm 0.02 (\mbox{stat}) \pm 0.03 (\mbox{sys})$ for the $\phi$ ($0.4 &lt; p_{T} &lt; 5.0$ GeV/$c$) and are constant with transverse momentum and collision centrality. The data are consistent with the unpolarized expectation of 1/3 and thus no evidence is found for the transfer of the orbital angular momentum of the colliding system to the vector-meson spins. Spin alignments for $K^{*0}$ and $\phi$ in $Au+Au$ collisions were also measured with respect to the particle’s production plane. The $\phi$ result, $\rho_{00}=0.41 \pm 0.02 (\mbox{stat}) \pm 0.04 (\mbox{sys})$, is consistent with that in $p+p$ collisions, $\rho_{00}=0.39 \pm 0.03 (\mbox{stat}) \pm 0.06 (\mbox{sys})$, also measured in this work. The measurements thus constrain the possible size of polarization phenomena in the production dynamics of vector mesons.

The data are consistent with the unpolarized expectation of 1/3 and thus no evidence is found for the transfer of the orbital angular momentum of the colliding system to the vector-meson spins. Spin alignments for $K^{*0}$ and $\phi$ in $Au+Au$ collisions were also measured with respect to the particle’s production plane. The $\phi$ result, $\rho_{00}=0.41 \pm 0.02 (\mbox{stat}) \pm 0.04 (\mbox{sys})$, is consistent with that in $p+p$ collisions, $\rho_{00}=0.39 \pm 0.03 (\mbox{stat}) \pm 0.06 (\mbox{sys})$, also measured in this work. The measurements thus constrain the possible size of polarization phenomena in the production dynamics of vector mesons.
