SOUSA's Swift Supernova Siblings
Swift has observed over three hundred supernovae in its first ten years.
Photometry from the Ultra-Violet Optical Telescope (UVOT) is being compiled in
the Swift Optical/Ultraviolet Supernovae Archive (SOUSA). The diversity of
supernovae leads to a wide dynamic range of intrinsic properties. The intrinsic
UV brightness of supernovae as a function of type and epoch allows one to
understand the distance ranges at which Swift can reliably detect supernovae.
The large Swift sample also includes supernovae from the same galaxy as other
Swift supernovae. Through the first ten years, these families include 34
supernovae from 16 host galaxies (two galaxies have each hosted three Swift
supernovae).Comment: Submitted to Proceedings of Science for the "10 Years of Swift"

Examining the Tragedy of the Commons Dilemma: Looking at the New Hampshire Fishing Industry
The Tragedy of the Commons is a widely known problem debated amongst economists for years. Even the topic of the Tragedy of the Commons when applied to fishing has been debated several times. The fishing industry is a major part of the culture and economy here in New Hampshire and the conversation how to properly tax and regulate it to combat this problem is one that has been taking place and will continue to take place for several years. The purpose of this project was to examine this problem at a state level and look at the relationship between State Tax Collections from fishing licenses, the number of Paid Fishing License Holders in New Hampshire and the GDP of the fishing industry. I overall had mixed results with some datasets representing significant statistical relationships, while others had marginal results. More research would need to be done in this area to make any certain conclusions. There are several areas in this topic that I couldn’t analyze for a variety of reasons, and this project merely scratches the surface of the amount of research left to be done
The Ultraviolet Brightest Type Ia Supernova 2011de
We present and discuss the UV/optical photometric light curves and absolute
magnitudes of the Type Ia supernova (SN) 2011de from the Swift
Ultraviolet/Optical Telescope. We find it to be the UV brightest SN Ia yet
observed--more than a factor of ten brighter than normal SNe Ia in the
mid-ultraviolet. This object is an extreme example of the differences seen in
the ultraviolet for objects which do not appear remarkable in the optical. We
find that the UV/optical brightness and broad light curves are broadly
consistent with additional flux from the shock of the ejecta hitting a red
giant companion. SN~2011de is either the first external interaction of a SN Ia
discovered in the UV or an extreme example of the intrinsic UV variations in
SNe Ia.Comment: 6 pages, including 4 figures and 1 table Submitted to ApJ Letters

Participation in higher education: A geodemographic perspective on the potential for further expansion in student numbers
Higher Education in England has expanded dramatically in the last ten years with the result that currently more than 30 per cent of young people go on to University. This upward trend in the participation rate is almost certain to continue, following the recommendations of a national committee of inquiry, the Dearing Committee (National Committee of Inquiry into Higher Education 1997). Participation rates vary substantially by region and by type of residential area, and an earlier paper by the present authors (Batey, Brown and Corver 1997) demonstrated the benefits of using a geodemographic classification system to explore the nature of this variation. The present paper builds on this foundation in order to examine the potential for further expansion of student numbers. A number of scenarios are developed which combine assumptions about factors that may determine the scope for expansion in particular regions and sub-regions. The results of this analysis are intended to inform current discussions about the implementation of certain of the Dearing Committee?s recommendations.

Action learning : co-creating value from collaborative sustainable projects
This article reports on the specific role that action learning plays in the promotion of sustainability and innovation in the Local Government sector. The study focuses on one organisation and the efforts of a senior manager to enact change. The senior manager utilized his participation in an MBA programme to bring the classroom learning into his business. As a consequence of the requirements of the programme and also the desire of the senior manager, he was able to instigate a change programme, which delivered measurable outcomes and had financial and cultural impact. This case study illustrates the favourable advantages of using action learning as an intervention approach by HEI’s in driving sustainable innovation in the Local Government sectorFinal Published versio
