Connecting Researchers to Repositories IMLS Project Report
Abstract: Despite a general consensus that making research data available is beneficial to many stakeholders, data sharing/curation is still not performed as an integrated step in most research lifecycles or common practice in the academic setting. Given many efforts over the last several years, why arenât repositories used more by researchers? This question was explored in two workshops meant to consider the next steps in developing the Data Curation Profiles (DCP) Toolkit. It identifies a unique approach to help efforts to increase data deposits in research data repositories from an entrepreneurial perspective
Assessing Perceived Usability of the Data Curation Profiles Toolkit Using the Technology Acceptance Model
The Data Curation Profiles Toolkit (DCPT) emerged out of a Purdue University Librariesâ 2004 initiative to engage in multidisciplinary research. It is a tool developed to assist librarians and other information professionals to conduct data interviews and identify needs of researchers in managing, sharing, or curating their data. The DCPT has been widely adopted and applied in various contexts but its usability as a tool has not been formally assessed. To address this need, we have conducted a survey of users of the DCPT. The survey included quantitative measures of potential influencing factors of using the DCPT and its perceived usability (its usefulness as a tool and its ease of use). Open-ended questions about usersâ experiences with the DCPT were also included to better understand the strengths and weaknesses of the tool as well as areas that could be improved. Factor analysis of the quantitative results and subsequent regression models revealed several underlying factors that affect the perceived usability of the DCPT. Responses to the open-ended questions revealed several themes of usersâ concerns: the amount of time required to use the DCPT, the structure and format of the DCPT, alignment of the DCPT with particular contexts, and the use of the DCPT to engage faculty and the library community. By correlating themes identified from the open-ended questions with the analysis of quantitative data, this paper provides the first set of empirical assessment of the DCPT that could help further improve the toolkitâs usability based on user needs and expectations. The methodology used in the study could readily be applied to assess and improve the utility of other tools used by data and information professionals

A Remark on the Estimation of Angular Power Spectra in the Presence of Foregrounds
It is common practice to estimate the errors on the angular power spectrum
which could be obtained by an experiment with a given angular resolution and
noise level. Several authors have also addressed the question of foreground
subtraction using multi-frequency observations. In such observations the
angular resolution of the different frequency channels is rarely the same. In
this report we point out how the ``effective'' beam size and noise level change
with ell in this case, and give an expression for the error on the angular
power spectrum as a function of ell.Comment: 3 pages, no figures, to appear in Phys Rev
X-ray Insights into the Nature of Quasars with Redshifted Broad Absorption Lines
We present observations of seven broad absorption line (BAL)
quasars at -2.516 with redshifted BAL troughs (RSBALs). Five of our
seven targets were detected by in 4-13 ks exposures with ACIS-S. The
values, values, and spectral energy
distributions of our targets demonstrate they are all X-ray weak relative to
expectations for non-BAL quasars, and the degree of X-ray weakness is
consistent with that of appropriately-matched BAL quasars generally.
Furthermore, our five detected targets show evidence for hard X-ray spectral
shapes with a stacked effective power-law photon index of . These findings support the presence of heavy X-ray
absorption ( cm) in RSBAL quasars,
likely by the shielding gas found to be common in BAL quasars more generally.
We use these X-ray measurements to assess models for the nature of RSBAL
quasars, finding that a rotationally-dominated outflow model is favored while
an infall model also remains plausible with some stipulations. The X-ray data
disfavor a binary quasar model for RSBAL quasars in general.Comment: 11 pages, 5 figures, and 3 table

Runaway Massive Binaries and Cluster Ejection Scenarios
The production of runaway massive binaries offers key insights into the
evolution of close binary stars and open clusters. The stars HD 14633 and HD
15137 are rare examples of such runaway systems, and in this work we
investigate the mechanism by which they were ejected from their parent open
cluster, NGC 654. We discuss observational characteristics that can be used to
distinguish supernova ejected systems from those ejected by dynamical
interactions, and we present the results of a new radio pulsar search of these
systems as well as estimates of their predicted X-ray flux assuming that each
binary contains a compact object. Since neither pulsars nor X-ray emission are
observed in these systems, we cannot conclude that these binaries contain
compact companions. We also consider whether they may have been ejected by
dynamical interactions in the dense environment where they formed, and our
simulations of four-body interactions suggest that a dynamical origin is
possible but unlikely. We recommend further X-ray observations that will
conclusively identify whether HD 14633 or HD 15137 contain neutron stars.Comment: Accepted to ApJ, 11 page
