Interim Report: Assessing the Future Landscape of Scholarly Communication
The Center for Studies in Higher Education, with generous funding from the Andrew W. Mellon Foundation, is conducting research to understand the needs and desires of faculty for inprogress scholarly communication (i.e., forms of communication employed as research is being executed) as well as archival publication. In the interest of developing a deeper understanding of how and why scholars do what they do to advance their fields, as well as their careers, our approach focuses in fine-grained analyses of faculty values and behaviors throughout the scholarly communication lifecycle, including sharing, collaborating, publishing, and engaging with the public. Well into our second year, we have posted a draft interim report describing some of our early results and impressions ased on the responses of more than 150 interviewees in the fields of astrophysics, archaeology, biology, economics, history, music, and political science.Our work to date has confirmed the important impact of disciplinary culture and tradition on many scholarly communication habits. These traditions may override the perceived "opportunities" afforded by new technologies, including those falling into the Web 2.0 category. As we have listened to our diverse informants, as well as followed closely the prognostications about the likely future of scholarly communication, we note that it is absolutely imperative to be precise about terms. That includes being clear about what is meant by "open access" publishing (i.e., using preprint or postprint servers for scholarship published in prestigious outlets versus publishing in new, untested open access journals, or the more casual individual posting of working papers, blogs, and other non-peer-reviewed work). Our research suggests that enthusiasm for technology development and adoption should not be conflated with the hard reality of tenure and promotion requirements (including the needs and goals of final archival publication) in highly competitive professional environments
The Non-homogeneous Poisson Process for Fast Radio Burst Rates
This paper presents the non-homogeneous Poisson process (NHPP) for modeling
the rate of fast radio bursts (FRBs) and other infrequently observed
astronomical events. The NHPP, well-known in statistics, can model changes in
the rate as a function of both astronomical features and the details of an
observing campaign. This is particularly helpful for rare events like FRBs
because the NHPP can combine information across surveys, making the most of all
available information. The goal of the paper is two-fold. First, it is intended
to be a tutorial on the use of the NHPP. Second, we build an NHPP model that
incorporates beam patterns and a power law flux distribution for the rate of
FRBs. Using information from 12 surveys including 15 detections, we find an
all-sky FRB rate of 586.88 events per sky per day above a flux of 1 Jy (95\%
CI: 271.86, 923.72) and a flux power-law index of 0.91 (95\% CI: 0.57, 1.25).
Our rate is lower than other published rates, but consistent with the rate
given in Champion et al. 2016.Comment: 19 pages, 2 figure

Boardman Lake Trail
Today in the United States, a significant portion of energy use is devoted to transportation needs. To address sustainable energy use in transportation, Team Wicked Awesome formed in the class LIB 322: “Wicked Problems in Sustainability” at Grand Valley State University in the winter of 2015. Looking to wicked problem solving methods, we examined Traverse City’s need for alternative options for transportation (other than single occupant vehicles). As an alternative mode of transportation, we looked into a number of ways to promote bicycle ridership and came to discover there was a tentative plan to complete a portion of the Traverse Area Recreation and Transportation Trail (T.A.R.T) that would give an entire side of the Boardman Lake more access to downtown and other neighborhoods via bicycle. We discovered that there was a lack of communication between local cycle groups, other community stakeholders and city officials in addressing the completion of the Boardman Lake Trail. We will hold a summit in order to open a dialogue with the community members and other stakeholders to discuss the state of the trail by integrating stakeholders and experts in a discussion panel. As part of the Wicked Problems model of problem solving we hope to bridge gaps that currently exist between these interested parties. We do not intend to create a new effort, but instead we will increase community involvement in the current effort and encourage city officials to place higher priority on the project. This summit will provide the public with information that will educate them not only on the prospects of the trail\u27s completion, but what obstacles exist, and what the community at large can do to help complete the trail. We hope this event will encourage citizens of the community to engage in collaborative effort and to take ownership and responsibility for the future of their city
Full Report: Scholarly Communication: Academic Values and Sustainable Models
This report presents five thickly-described interdisciplinary case studies that explore academic value systems as they influence publishing behavior and attitudes of University of California, Berkeley faculty. The case studies are based on direct interviews with relevant stakeholders -- faculty, advancement reviewers, librarians, and editors -- in five fields: chemical engineering, anthropology, law and economics, English-language literature, and biostatistics. The results of the study strongly confirm the vital role of peer review in faculty attitudes and actual publishing behavior. There is much more experimentation, however, with regard to means of in-progress communication, where single means of publication and communication are not fixed so deeply in values and tradition as they are for final, archival publication. We conclude that approaches that try to "move" faculty and deeply embedded value systems directly toward new forms of archival, "final" publication are destined largely to failure in the short-term. From our perspective, a more promising route is to (1) examine the needs of scholarly researchers for both final and in-progress communications, and (2) determine how those needs are likely to influence future scenarios in a range of disciplinary areas
A Millisecond Interferometric Search for Fast Radio Bursts with the Very Large Array
We report on the first millisecond timescale radio interferometric search for
the new class of transient known as fast radio bursts (FRBs). We used the Very
Large Array (VLA) for a 166-hour, millisecond imaging campaign to detect and
precisely localize an FRB. We observed at 1.4 GHz and produced visibilities
with 5 ms time resolution over 256 MHz of bandwidth. Dedispersed images were
searched for transients with dispersion measures from 0 to 3000 pc/cm3. No
transients were detected in observations of high Galactic latitude fields taken
from September 2013 though October 2014. Observations of a known pulsar show
that images typically had a thermal-noise limited sensitivity of 120 mJy/beam
(8 sigma; Stokes I) in 5 ms and could detect and localize transients over a
wide field of view. Our nondetection limits the FRB rate to less than
7e4/sky/day (95% confidence) above a fluence limit of 1.2 Jy-ms. Assuming a
Euclidean flux distribution, the VLA rate limit is inconsistent with the
published rate of Thornton et al. We recalculate previously published rates
with a homogeneous consideration of the effects of primary beam attenuation,
dispersion, pulse width, and sky brightness. This revises the FRB rate downward
and shows that the VLA observations had a roughly 60% chance of detecting a
typical FRB and that a 95% confidence constraint would require roughly 500
hours of similar VLA observing. Our survey also limits the repetition rate of
an FRB to 2 times less than any known repeating millisecond radio transient.Comment: Submitted to ApJ. 13 pages, 9 figure

The process of using Outcome Mapping to construct the change management framework (CMF) involved mobilization of planning and assessment teams (Project Steering Committee and Change Management Taskforce). The process was guided and facilitated by an external consultant. The study reports on this process
