Non locally trivializable CRCR line bundles over compact Lorentzian CRCR manifolds

We consider compact $CR$ manifolds of arbitrary $CR$ codimension that satisfy certain geometric conditions in terms of their Levi form. Over these compact $CR$ manifolds, we construct a deformation of the trivial $CR$ line bundle over $M$ which is topologically trivial over $M$ but fails to be even locally $CR$ trivializable over any open subset of $M$. In particular, our results apply to compact Lorentzian $CR$ manifolds of hypersurface type.Comment: to appear in Annales de l'Institut Fourie

On the Cauchy problem for the debar operator

We present new results concerning the solvability, of lack thereof, in the Cauchy problem for the debar operator, with initial values assigned on a weakly pseudoconvex hypersurface, and provide illustrative examples.Comment: This is the final version, which is appearing in Arkiv foer Mathemati

Being a woman: Perspectives of Low German-Speaking Mennonite women

Sherpa Romeo green journal. Permission to archive accepted author manuscriptUnderstanding the beliefs and knowledge related to women’s sexuality is important when working with unique religious groups in order to provide culturally appropriate care. An exploratory, descriptive qualitative study generated knowledge, beliefs and practices related to menstruation, ovulation and family planning among Low German-speaking Mennonite women (n = 38). There is a pervasive silence that surrounds sexuality among this group with limited understanding of the physiological changes they experience. Honoring religious principles and family and community expectations through acceptable female behavior is essential. Adherence to religious principles varies by family but is not shared with the group to avoid disfavor
