Irrationality as a determinant of gender stereotyping towards women
Irrational thinking can be considered to be the key concept of Rational Emotive Behavior Therapy (REBT) and has been conceptualized as rigid und inflexible adherence to
absolutistic thinking and person evaluations. Based on this definition we predicted a positive relation between irrationality and gender stereotyping towards women. Established reliable scales were used to assess the constructs in a non-student sample (N = 240). In line with assumptions we were able to detect a significant positive relation between irrationality and gender stereotyping while controlling for the Big Five, life satisfaction, sex and age. Implications for interventions concerning stereotypes are outlined
Charm rescattering contribution in rare decay
Following the experimental results from LHCb on the rare decay , we investigate the possibility where this process is dominated by
a double charm rescattering. The decay to double charm channels have a
weak topology that is favoured in comparison with the direct production of
in the final state, suppressed by quark annihilation. The decay
amplitude for with decaying first to double charm
channels is described by a charm penguin diagram, represented by charm hadronic
triangle loops, which reach the final state of interest after or transitions. We show that these
processes give rise to non-resonant amplitudes with a clear signature in the
Dalitz plot. In a near future, the new data from LHCb run II will be able to
confirme if the main hypotheses of this work is correct and the dominant
mechanism to produce from the decay of is through charm
rescattering
The Dynamical History of Chariklo and its Rings
Chariklo is the only small Solar system body confirmed to have rings. Given
the instability of its orbit, the presence of rings is surprising, and their
origin remains poorly understood. In this work, we study the dynamical history
of the Chariklo system by integrating almost 36,000 Chariklo clones backwards
in time for one Gyr under the influence of the Sun and the four giant planets.
By recording all close encounters between the clones and planets, we
investigate the likelihood that Chariklo's rings could have survived since its
capture to the Centaur population. Our results reveal that Chariklo's orbit
occupies a region of stable chaos, resulting in its orbit being marginally more
stable than those of the other Centaurs. Despite this, we find that it was most
likely captured to the Centaur population within the last 20 Myr, and that its
orbital evolution has been continually punctuated by regular close encounters
with the giant planets. The great majority (> 99%) of those encounters within
one Hill radius of the planet have only a small effect on the rings. We
conclude that close encounters with giant planets have not had a significant
effect on the ring structure. Encounters within the Roche limit of the giant
planets are rare, making ring creation through tidal disruption unlikely
