Lessons from Women Leaders: The Impact of Professional Development

Professional development is learner-centered, where the responsibility to engage in further educational experiences belongs to the individual and is a critical way to prepare for career advancement. In higher education, cisgender women do not hold the majority of chief student affairs officers (CSAO) positions, which is unexpected given their representation in entry and mid-level positions (Shea Gasser, 2014). This article reviews a grounded theory study conducted to better understand the phenomenon of professional development experiences of women CSAOs and how professional development impacts career ascension of women in student affairs

Note on a Conjecture of Wegner

The optimal packings of n unit discs in the plane are known for those natural numbers n, which satisfy certain number theoretic conditions. Their geometric realizations are the extremal Groemer packings (or Wegner packings). But an extremal Groemer packing of n unit discs does not exist for all natural numbers n and in this case, the number n is called exceptional. We are interested in number theoretic characterizations of the exceptional numbers. A counterexample is given to a conjecture of Wegner concerning such a characterization. We further give a characterization of the exceptional numbers, whose shape is closely related to that of Wegner's conjecture.Comment: 5 pages; Contributions to Algebra and Geometry, Vol.52 No1 April 201
