As Spring weather beckons us : outdoors, our hearts anticipate coming attractions of the season such as Easter, commencements at our various institutions, and then, of course, the next ACL annual conference. Each event brings new life, renewal, resurrection, rejuvenation

On Helly number for crystals and cut-and-project sets

We prove existence of finite Helly numbers for crystals and for cut-and-project sets with convex windows; also we prove exact bound of $k+6$ for the Helly number of a crystal consisting of $k$ copies of a single lattice. We show that there are sets of finite local complexity that do not have finite Helly numbers

On \pi-surfaces of four-dimensional parallelohedra

We show that every four-dimensional parallelohedron P satisfies a recently found condition of Garber, Gavrilyuk & Magazinov sufficient for the Voronoi conjecture being true for P. Namely we show that for every four-dimensional parallelohedron P the group of rational first homologies of its \pi-surface is generated by half-belt cycles.Comment: 16 pages, 7 figure

Have you ever felt cramped? Out of space? Short of room? Working on this issue of The Christian Librarian is a continuation of a theme in my life lately. This is issue is jammed packed with articles and features and ACL Conference information that must go out to readers. There wasn\u27t even room for pull-quotes -- those attention grabbing statements that highlight each article in hopes of attracting you to read further, and add an attractive graphic element to each page. We\u27ve even added extra pages so there would be enough room to fit it all in

Belt distance between facets of space-filling zonotopes

For every d-dimensional polytope P with centrally symmetric facets we can associate a "subway map" such that every line of this "subway" corresponds to set of facets parallel to one of ridges P. The belt diameter of P is the maximal number of line changes that you need to do in order to get from one station to another. In this paper we prove that belt diameter of d-dimensional space-filling zonotope is not greater than $\lceil \log_2\frac45d\rceil$. Moreover we show that this bound can not be improved in dimensions d at most 6.Comment: 17 pages, 5 figure

Where in the World Are the Lesbians?

In 2001 I became, as far as I can tell, the first person hired at a Catholic university specifically because of my work in LGBTQ studies. I am blessed, as it were, with a departmental colleague who publishes widely in postcolonial queer studies, a colleague in another department who teaches queer U.S. history every two years, and many supportive friends on the faculty. Still, I am the most public face of LGBTQ studies on campus, and if a new queer studies course is added to the curriculum, I am likely to be the one who develops it. Over the years I have come to realize that my role is not unusual, Catholic university or not. I was in a similar position at a large state university for seven years and have several friends and acquaintances across the country at a variety of institutions in similar spots. Most of us are not lucky enough to work among even a small clustering of others teaching in our field, even if we do have colleagues who assign queer theory in their courses or publish on queer topics. Of necessity this makes us chameleons, generalists. As an interdisciplinary scholar with an interdisciplinary doctorate, I feel suited to the role
