Communicating Mission and Building Library Brand Using Taglines, Slogans, or Logos
We live in a visual society. Everywhere you
go, you can see various eye-catching logos, trademarks, service marks, and other identifying marks for organizations. These extend to the Internet, perhaps the most eye-appealing resource ever, where librarians increasingly use its power and reach to
communicate with their publics using Flash, animated GIFs, and both audio and video messages

Colin Mochrie vs. Jesus H. Christ: Messages About Masculinities and Fame in Online Video Conversations
With the availability of relatively easy-to-use tools for online video creation and distribution, people are
increasingly producing videos not just for artistic
expression, but also as a form of communication. This
article examines two types of online video
conversations, one within a specific online subculture,
and one a series of responses to one particularly wellknown
video. Videos lend themselves to the expression
of ambiguity, contradictory meanings, taboo topics,
and emotions. Within these two video conversations,
topics include discussions of masculinity, identity, and
fame.published or submitted for publicationis peer reviewe
A Direct Multigrid Poisson Solver for Oct-Tree Adaptive Meshes
We describe a finite-volume method for solving the Poisson equation on
oct-tree adaptive meshes using direct solvers for individual mesh blocks. The
method is a modified version of the method presented by Huang and Greengard
(2000), which works with finite-difference meshes and does not allow for shared
boundaries between refined patches. Our algorithm is implemented within the
FLASH code framework and makes use of the PARAMESH library, permitting
efficient use of parallel computers. We describe the algorithm and present test
results that demonstrate its accuracy.Comment: 10 pages, 6 figures, accepted by the Astrophysical Journal; minor

A general hybrid radiation transport scheme for star formation simulations on an adaptive grid
Radiation feedback plays a crucial role in the process of star formation. In
order to simulate the thermodynamic evolution of disks, filaments, and the
molecular gas surrounding clusters of young stars, we require an efficient and
accurate method for solving the radiation transfer problem. We describe the
implementation of a hybrid radiation transport scheme in the adaptive
grid-based FLASH general magnetohydrodynamics code. The hybrid scheme splits
the radiative transport problem into a raytracing step and a diffusion step.
The raytracer captures the first absorption event, as stars irradiate their
environments, while the evolution of the diffuse component of the radiation
field is handled by a flux-limited diffusion (FLD) solver. We demonstrate the
accuracy of our method through a variety of benchmark tests including the
irradiation of a static disk, subcritical and supercritical radiative shocks,
and thermal energy equilibration. We also demonstrate the capability of our
method for casting shadows and calculating gas and dust temperatures in the
presence of multiple stellar sources. Our method enables radiation-hydrodynamic
studies of young stellar objects, protostellar disks, and clustered star
formation in magnetized, filamentary environments.Comment: 16 pages, 15 figures, accepted to Ap

Moving boulders in flash floods and estimating flow conditions using boulders in ancient deposits
Boulders moving in flash floods cause considerable damage and casualties. More and bigger boulders move in flash floods than predicted from published theory. The interpretation of flow conditions from the size of large particles within flash flood deposits has, until now, generally assumed that the velocity (or discharge) is unchanging in time (i.e. flow is steady), or changes instantaneously between periods of constant conditions. Standard practice is to apply theories developed for steady flow conditions to flash floods, which are however inherently very unsteady flows. This is likely to lead to overestimates of peak flow velocity (or discharge). Flash floods are characterised by extremely rapid variations in flow that generate significant transient forces in addition to the mean-flow drag. These transient forces, generated by rapid velocity changes, are generally ignored in published theories, but they are briefly so large that they could initiate the motion of boulders. This paper develops a theory for the initiation of boulder movement due to the additional impulsive force generated by unsteady flow, and discusses the implications. Keywords
