A comprehensive study of dust formation and evolution in core collape supernovae

Detection of large amounts of dust in high redshift galaxies suggests that core collapse supernovae (CCSNe) may play a critical role in the dust budget of galaxies in the early universe, when galaxies are only a few hundred million years old. At an age of only 1Gyr, asymptotic giant branch (AGB) stars may not have had the time to become significant dust contributors, leaving CCSNe as an alternative explanation since they quickly evolve and return their material to the surrounding interstellar medium. For the past three years, I have been observing the CCSNe 2007it and 2007od with Gemini, Hubble Space Telescope, and Spitzer Space Telescope in the optical and infrared to look for indicators of dust formation, which appear within the first few years after explosion. The data sets contain large temporal and wavelength coverage, and have led to some unusual and interesting results. In both cases there is evidence for interaction with surrounding circumstellar material (CSM), although neither was classified as a Type IIn. SN 2007it was found to be oxygen rich with a 56Ni mass quite large for a Type IIP, while SN 2007od is oxygen poor with a very low, over two orders of magnitude less, 56Ni mass. Scattered light echoes also seem to be present in both SNe. An estimated 10-4 solar masses of new dust has formed in each SN, consistent with other CCSNe, but still significantly less than needed to account for the amount of dust seen at high redshift. I will discuss these results and their implications for SNe as major dust contributors in the universe

Old Stories, New Narratives: Public Archaeology and the Politics of Display at Georgia\u27s Official Southeastern Indian Interpretive Center

Presenting a case study of an American Indian exhibit at the Funk Heritage Center, I critically examine how this museum’s ideologies and preferred pedagogies shape public discourse about Southeastern Indians in the past and present. Using the methodology of Visitor Studies, this public archaeology project illustrates the benefits of incorporating applied anthropology into museological practice through collaboration with museum staff, volunteers, visitors, and American Indians. Operating within the theoretical frameworks of Charles R. Garoian (2001) and Barbara Kirshenblatt-Gimblett (1991), my results imply that inserting archaeological narratives into institutional pedagogy alters a museum’s traditional “performance” of the past by challenging its own authority; ultimately, I show how this process can increase viewer awareness about the politics of display

Pathways to non-complex assistive technology for HACC clients in WA : full report

The project aims to identify, evaluate and make recommendations to improve the pathways by which West Australian (WA) Home and Community Care (HACC) clients access daily living equipment. Otherwise known as assistive technology (AT), these devices are largely non-complex and often low cost. Funded by HACC and conducted within the context of the WA Assessment Framework (WAAF), the project seeks to answer the following question:&nbsp; &nbsp; How can aids and equipment be most effectively assessed, accessed, funded and used?The research is designed to inform WA state government policy and Commonwealth HACC government policy in relation to the funding of HACC client access to assistive technology. Whilst set in WA, the topic and findings have relevance to HACC in other Australian states and territories, as well as other aspects of aged care policy, other sectors such as disability, and other areas of inquiry such as competency standards and consumer self-direction.</div

A Dream of Spring: Creation of an IR Managers Forum

Sometimes it’s hard to find answers for work‐related questions. This difficulty is compounded when one lacks the means to engage with a community of peers who face similar situations and problems. As institutional repository (IR) managers, we found ourselves with access to resources and listservs that didn’t quite fit our needs. Available discussion spaces were either too general in scope, drowning out repository‐specific concerns; or too narrowly focused on platform‐specific issues and technical details. Lacking an appropriate forum, we decided to create a discussion space for IR managers. The IR Manager Forum (https://groups.google.com/forum/#!forum/irmanagers) is designed to foster a community of practice for reposi- tory managers, regardless of software implementation, institutional setting, or technical expertise. Using the Goo- gle Groups platform, members can post and view threaded messages in an online interface or by e‐mail. Conversations in this space have the potential to help IR managers develop their repository policies and local practices. The authors hope that the forum will also support cross‐platform comparisons to identify useful fea- tures and limitations of various software, areas for practical improvement, and larger trends in institutional repos- itories that speak to their future direction. This paper covers how IR managers from the University of Florida, University of North Texas, Texas A&M University, and University of Massachusetts Amherst created the IR Man- agers Forum. It also gives an overview of the forum’s usage and growth over the first year and a half, and lessons learned along the way

Age and Growth of Spotted Sand Bass, Paralabrax maculatofasciatus, in Bahia de Los Angeles, Baja California, Mexico, with Age Validation using Otolith Edge Analysis

Spotted sand bass, Paralabrax maculatofasciatus, were collected from Bahia de Los Angeles, Baja California, Mexico covering as wide a size range as possible over four seasons (spring, summer, fall, and winter). Age was estimated and growth parameters calculated from growth zones counted in transverse otolith sections. An otolith edge analysis indicated an opaque growth zone was deposited once per year during the summer, validating the annual periodicity. Spotted sand bass from this region are fast growing with a relatively short life span of up to 11 years. Growth differs from the disjunct Pacific coast population by having a higher growth rate and a shorter longevity
