Examining mindfulness and its relation to self-differentiation and alexithymia
Published online first in 10 July 2013Research supports the association between
mindfulness, emotion regulation, stress reduction, and
interpersonal/relational wellness. The present study evaluated
the potential effect of mindfulness on some indicators of psychological
imbalance such as low self-differentiation and
alexithymia. In this cross-sectional study, a sample of 168 undergraduates
(72 % women) completed measures of perceived
mindfulness (CAMS-R and PHLMS), self-differentiation (SIPI),
and alexithymia (TAS-20). Results revealed positive
correlations between the different dimensions of mindfulness
and negative correlations between those dimensions, selfdifferentiation,
and alexithymia. The dimensions of quality of
mindfulness and acceptance were mediators in the relationship
between self-differentiation and alexithymia. A nonsignificant
interaction between gender and alexithymia was found. All
mindfulness dimensions, but self-differentiation, contributed
to explain the allocation of the non-alexithymic group. These
results indicate that mindfulness seems to be a construct with
great therapeutic and research potential at different levels,
suggesting that some aspects of mindfulness seem to promote
a better self-differentiation and prevent alexithymia
J/psi production from proton-proton collisions at sqrt(s) = 200 GeV
J/psi production has been measured in proton-proton collisions at sqrt(s)=
200 GeV over a wide rapidity and transverse momentum range by the PHENIX
experiment at RHIC. Distributions of the rapidity and transverse momentum,
along with measurements of the mean transverse momentum and total production
cross section are presented and compared to available theoretical calculations.
The total J/psi cross section is 3.99 +/- 0.61(stat) +/- 0.58(sys) +/-
0.40(abs) micro barns. The mean transverse momentum is 1.80 +/- 0.23(stat) +/-
0.16(sys) GeV/c.Comment: 326 authors, 6 pages text, 4 figures, 1 table, RevTeX 4. To be
submitted to PRL. Plain text data tables for the points plotted in figures
for this and previous PHENIX publications are (or will be) publicly available

Centrality Dependence of Charm Production from Single Electrons in Au+Au Collisions at sqrt(s_NN) = 200 GeV
The PHENIX experiment has measured mid-rapidity transverse momentum spectra
(0.4 < p_T < 4.0 GeV/c) of single electrons as a function of centrality in
Au+Au collisions at sqrt(s_NN) = 200 GeV. Contributions to the raw spectra from
photon conversions and Dalitz decays of light neutral mesons are measured by
introducing a thin (1.7% X_0) converter into the PHENIX acceptance and are
statistically removed. The subtracted ``non-photonic'' electron spectra are
primarily due to the semi-leptonic decays of hadrons containing heavy quarks
(charm and bottom). For all centralities, charm production is found to scale
with the nuclear overlap function, T_AA. For minimum-bias collisions the charm
cross section per binary collision is N_cc^bar/T_AA = 622 +/- 57 (stat.) +/-
160 (sys.) microbarns.Comment: 326 authors, 4 pages text, 3 figures, 1 table, RevTeX 4. To be
