The Relationship between Positive Thinking, Religion, and Health from the Perspectives of Arab University Students

Background: The population of Arab Americans (AA) in the United States continues to increase in recent decades. The perceptions of AA university students will be of interest as they are younger than any other group in America, but very few studies explore their opinions especially with regards to topics involving religion, health, and mode of thinking as proposed in this study. Researchers have also suggested that a limitation in much of the research that currently exists on the topic of spirituality and religion is that it primarily focuses on Christian samples, and that future studies should include individuals from more diverse faith traditions for researchers to gain a more thorough understanding of the relationship between religion and health. Purpose: Main Purpose of this qualitative study is to explore the relationship between positive thinking, religion, and health from the perspectives of Arab university students. Design and Methods: In this descriptive qualitative study, two focus groups were recruited. Content analysis was used to come up with the categories and subcategories. Findings: Three distinct categories were identified: Positive thinking enhances overall health, Positive influence of religion on way of thinking/health, and negative influence of religion on way of thinking/health. Practice Implications: All the findings will provide insights for health professionals to provide more culturally competent care to their patients accounting for their faith-based health beliefs and ultimately helping to eliminate health disparities

Global Analysis of Helicity Parton Densities and Their Uncertainties

We present a new analysis of the helicity parton distributions of the nucleon. The analysis takes into account the available data from inclusive and semi-inclusive polarized deep inelastic scattering, as well as from polarized pp scattering at RHIC. For the first time, all theoretical calculations are performed fully at next-to-leading order (NLO) of perturbative QCD, using a method that allows to incorporate the NLO corrections in a very fast and efficient way in the analysis. We find evidence for a rather small gluon polarization in the nucleon, over a limited region of momentum fraction, and for interesting flavor patterns in the polarized sea.Comment: 4 pages, 3 figure

J/psi suppression at forward rapidity in Au+Au collisions at sqrt(s_NN)=39 and 62.4 GeV

We present measurements of the J/psi invariant yields in sqrt(s_NN)=39 and 62.4 GeV Au+Au collisions at forward rapidity (1.2<|y|<2.2). Invariant yields are presented as a function of both collision centrality and transverse momentum. Nuclear modifications are obtained for central relative to peripheral Au+Au collisions (R_CP) and for various centrality selections in Au+Au relative to scaled p+p cross sections obtained from other measurements (R_AA). The observed suppression patterns at 39 and 62.4 GeV are quite similar to those previously measured at 200 GeV. This similar suppression presents a challenge to theoretical models that contain various competing mechanisms with different energy dependencies, some of which cause suppression and others enhancement.Comment: 365 authors, 10 pages, 11 figures, 4 tables.

Measurement of higher cumulants of net-charge multiplicity distributions in Au++Au collisions at sNN=7.7−200\sqrt{s_{_{NN}}}=7.7-200 GeV

We report the measurement of cumulants ($C_n, n=1\ldots4$) of the net-charge distributions measured within pseudorapidity ($|\eta|<0.35$) in Au$+$Au collisions at $\sqrt{s_{_{NN}}}=7.7-200$ GeV with the PHENIX experiment at the Relativistic Heavy Ion Collider. The ratios of cumulants (e.g. $C_1/C_2$, $C_3/C_1$) of the net-charge distributions, which can be related to volume independent susceptibility ratios, are studied as a function of centrality and energy. These quantities are important to understand the quantum-chromodynamics phase diagram and possible existence of a critical end point. The measured values are very well described by expectation from negative binomial distributions. We do not observe any nonmonotonic behavior in the ratios of the cumulants as a function of collision energy. The measured values of $C_1/C_2 = \mu/\sigma^2$ and $C_3/C_1 = S\sigma^3/\mu$ can be directly compared to lattice quantum-chromodynamics calculations and thus allow extraction of both the chemical freeze-out temperature and the baryon chemical potential at each center-of-mass energy.Comment: 512 authors, 8 pages, 4 figures, 1 table. v2 is version accepted for publication in Phys.
