The University as Publisher: Summary of a Meeting Held at UC Berkeley on November 1, 2007
With the advent of electronic publishing, the scholarly communication landscape at universities has become increasingly diverse. Multiple stakeholders including university presses, libraries, and central IT departments are challenged by the increasing volume and the rapidity of production of these new forms of publication in an environment of economic uncertainties. As a response to these increasing pressures, as well as the recent publication of important reports and papers on the topic, the Center for Studies in Higher Education (CSHE) convened a meeting of experts titled, The University as Publisher. The event was sponsored as part of the A.W. Mellon Foundation-funded Future of Scholarly Communication project at CSHE.Our goal was to explore among stakeholders -- faculty, publishers, CIOs, librarians, and researchers -- the implications of the academic community, in some structure, taking over many, if not all, aspects of scholarly publishing. Two themes were the focus of the public panels: Institutional Roles in Evaluation, Quality Assessment, and Selection and Structuring and Budgeting Models for Publishing within the University Community. Our discussions included the importance of distinguishing between informal dissemination and formal publishing and the challenges that each presents to the university community. The harsh economic realities of high-quality formal scholarly publication, not least of which are managing peer review and editorial processes, were emphasized. Understanding disciplinary needs was cited as paramount throughout the discussions; the needs and traditions of scholars in the sciences and humanities, as well as among myriad disciplines, will likely demand different dissemination and publishing models and solutions. An additional theme that emerged was acknowledging the diverse forms electronic dissemination takes in the academy and the need to foster a spectrum of alternatives in publication forms, business models, and the peer review process. Budgetary and academic freedom concerns were explored as well. Regarding the expensive infrastructure required for electronic dissemination and publishing, it was agreed that there is enormous duplication among the university press, IT, and the library

Stability of planets in triple star systems
Context: Numerous theoretical studies of the stellar dynamics of triple
systems have been carried out, but fewer purely empirical studies that have
addressed planetary orbits within these systems. Most of these empirical
studies have been for coplanar orbits and with a limited number of orbital
parameters. Aims: Our objective is to provide a more generalized empirical
mapping of the regions of planetary stability in triples by considering both
prograde and retrograde motion of planets and the outer star; investigating
highly inclined orbits of the outer star; extending the parameters used to all
relevant orbital elements of the triple's stars and expanding these elements
and mass ratios to wider ranges that will accommodate recent and possibly
future observational discoveries. Methods: Using N-body simulations, we
integrated numerically the various four-body configurations over the parameter
space, using a symplectic integrator designed specifically for the integration
of hierarchical multiple stellar systems. The triples were then reduced to
binaries and the integrations repeated to highlight the differences between
these two types of system. Results: This established the regions of secular
stability and resulted in 24 semi-empirical models describing the stability
bounds for planets in each type of triple orbital configuration. The results
were then compared with the observational extremes discovered to date to
identify regions that may contain undiscovered planets.Comment: 12 pages, 8 figures, 14 tables. Accepted for publication in Astronomy

Electrolytic lesions within central complex neuropils of the cockroach brain affect negotiation of barriers
Animals must negotiate obstacles in their path in order to successfully function within natural environments. These actions require transitions from walking to other behaviors, many of which are more involved than simple reflexes. For these behaviors to be successful, insects must evaluate objects in their path and then use that information to change posture or re-direct leg movements. Some of this control may occur within a region of the brain known as the central complex (CC). We used discrete electrolytic lesions to examine the role of certain sub-regions of the CC in various obstacle negotiation behaviors. We found that cockroaches with lesions to the protocerebral bridge (PB) and ellipsoid body (EB) exhibit abnormalities in turning and dealing with shelf-like objects; whereas, individuals with lesions to the fan-shaped body (FB) and lateral accessory lobe (LAL), exhibit abnormalities of those behaviors as well as climbing over blocks and up walls to a horizontal plane. Abnormalities in block climbing include decreased success rate, changes in climbing strategy, and delayed response to the block. Increases in these abnormal behaviors were significant in individuals with lesions to the FB and LAL. Although turning abnormalities are present in individuals with lesions to the LAL, EB and the lateral region of the FB, there are some differences in how these deficits present. For instance, the turning deficits seen in individuals with lateral FB lesions only occurred when turning in the direction opposite to the side of the brain on which the lesion occurred. By contrast, individuals with lesions to the EB and LAL exhibited turning abnormalities in both directions. Lesions in the medial region of the FB did not result in directional turning deficits, but in abnormalities in block climbing
