Stabilized Galerkin for transient advection of differential forms
No full textWe deal with the discretization of generalized transient advection problems for differential forms on bounded spatial domains. We pursue an Eulerian method of lines approach with explicit timestepping. Concerning spatial discretization we extend the jump stabilized Galerkin discretization proposed in [H. Heumann and R. Hiptmair, Stabilized Galerkin methods for magnetic advection, Math. Modelling Numer. Analysis, 47 (2013), pp. 1713{ 1732] to forms of any degree and, in particular, advection velocities that may have discontinuities resolved by the mesh. A rigorous a priori convergence theory is established for Lipschitz continuous velocities, conforming meshes and standard nite element spaces of discrete differential forms. However, numerical experiments furnish evidence of the good performance of the new method also in the presence of jumps of the advection velocity
Audrey Heumann Regen \u2756 (BardCorps)
No full textAudrey Heumann Regen returned to Bard in 2001 for her 45th reunion. Regan was a high achieving high-school student with a nagging case of test anxiety who came to Bard for its unorthodox philosophy and strong arts curriculum. She remembers Buzz Gummere admitting her because of her wide range of interests. Her senior project advisor was Dorothy Dulles Bourne, and her project focused on the educational theories of John Dewey.
She recalls a tradition where Eleanor Roosevelt would come to Bard every Christmas season to read Dickens\u27 A Christmas Carol to the students. One year, a fellow student, a polio survivor, wanted to honor Mrs. Roosevelt by opening the door for her. Audrey remembers this as a poignant moment, watching Mrs. Roosevelt give him time because she knew the effort this took.
Regen remembers Bard as a much smaller place, with 250 students and only a few established buildings. She describes the quality as ‘homey’ or ‘hamish’ with students congregating at the little coffee shop in Stone Row. It was a very wholesome and healthy isolation, that you could concentrate without a great many distractions, on your studies. At the same time, she describes Bard\u27s reputation during her day as a wild place, with strange clothing, wild behaviors, and a great deal of sexual experimentation.
Campus jobs for Audrey included delivering the mail to faculty, and in one instance, tutoring a professor’s child in reading, Erica DeGre (now Rikki Ducornet).
Regen also remembers attending a synagogue in Poughkeepsie for Jewish holidays. Students later decided to hold ceremonies for Jewish High Holy Days on campus.
She continues to show support for the college saying: “Bard took a chance on me, and I would always be here for Bard.”
Audrey H. Regen passed away on May 30, 2017.https://digitalcommons.bard.edu/oral_hist/1031/thumbnail.jp

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
