- This article examines the effect of religion on positional concerns using survey experiments. We focus on two of the dimensions of religion degree of religiosity and religious festivals. By conducting the experiments during both the most important day of Ramadan (the Night of Power) and a day outside Ramadan, we find that Ramadan overall has a small and negative impact on positional concerns. Detailed analyses based on the sorting of individuals degree of religiosity reveal that the decrease in the degree of positional concerns during Ramadan is mainly explained by a decrease in positionality among individuals with a low degree of religiosity.

- We derive analytically the phase diagram of a two-component Bose gas confined in an anharmonic potential, which becomes exact and universal in the limit of weak interactions and small anharmonicity of the trapping potential. The transitions between the different phases, which consist of vortex states of single and multiple quantization, are all continuous because of the addition of the second component.

- We investigate the rotational response of both nondipolar and dipolar Bose-Einstein condensates confined in an annular potential via minimization of the energy in the rotating frame. For the nondipolar case we identify certain phases which are associated with different vortex configurations. For the dipolar case, assuming that the dipoles are aligned along some arbitrary and tunable direction, we study the same problem as a function of the orientation angle of the dipole moment of the atoms.
