Ultra Compact Dwarfs In The Core Of The Perseus Cluster: Ucd Formation Via Tidal Stripping, S. Penny, D. Forbes, J. Strader, C. Usher, J. Brodie, Aaron Romanowsky

Faculty Research, Scholarly, and Creative Activity

We present the results of a Keck/DEIMOS survey of Ultra Compact Dwarfs (UCDs) in the Perseus Cluster core. We confirm cluster membership for 14 UCDs, with radial velocities ~5300 km s−1. Two of these confirmed Perseus UCDs have extremely blue colours (B−R<0.6 mag), reside in star forming filaments surrounding NGC 1275, and have likely formed as massive star clusters in the last ~100 Myr. We also measure a central velocity dispersion of a third, UCD13 (σ0=38±8 km s−1), the most extended UCD in our sample. We determine it to have radius Re=85±1.1 pc, a dynamical mass of (2.3±0.8)×108 M⊙, and a metallicity [Z/H]=−0.52+0.33−0.29 dex. UCD13 and the cluster's central galaxy, NGC 1275, have a projected separation of 30 kpc and a radial velocity difference of ~20 km s−1. Based on its size, red colour, internal velocity dispersion, dynamical mass, metallicity and proximity to NGC 1275, we argue that UCD13 is likely the remnant nucleus of a tidally stripped dE, with this progenitor dE having MB≈−16 mag and mass ∼109 M⊙.

A Study Of College Student Attitudes And Behaviors Related To Recycling, Mark Allen Wilcox

Dissertations and Theses @ UNI

There is an abundance of research on environmental attitudes and recycling; specifically however college students are very under represented. This population is one that is very important as these individuals will be the ones making decisions, privately and politically, with regards to recycling programs in their communities. By understanding their attitudes and behaviors in college, those designing recycling programs can develop and modify programs to suit their needs, and education programs can be prepared to better inform these individuals. The purpose of this study was to study the attitudes and behaviors of college students related to recycling. To accomplish this, …

Summary Tables: Gloucester County, Virginia Shoreline Inventory Report, Marcia Berman, Karinna Nunez, Sharon Killeen, Tamia Rudnicky, Julie Bradshaw, Karen Duhring, David Stanhope, Kory Angstadt, Christine Tombleson, David Weiss, Carl Hershner

Reports

The Shoreline Inventory Summary Tables quantify observed conditions based on river systems, such as the combined length of linear features (e.g. shoreline miles surveyed, miles of bulkhead and revetment), the total number of point features (e.g. docks, boathouses, boat ramps) & total acres of polygon features (tidal marshes).

City Of Newport News, Virginia Shoreline Inventory Report Methods And Guidelines, Marcia Berman, Karinna Nunez, Sharon Killeen, Tamia Rudnicky, Julie Bradshaw, Karen Duhring, Kory Angstadt, Alexandra Procopi, David Weiss, Carl Hershner

Reports

The data inventory developed for the Shoreline Inventory is based on a three tiered shoreline assessment approach. This assessment characterizes conditions that can be observed from a small boat navigating along the shoreline or by using observations made remotely at the desktop using high resolution imagery. The three tiered shoreline assessment approach divides the shorezone into three regions:

1) the immediate riparian zone, evaluated for land use; 2) the bank, evaluated for height, stability, cover and natural protection; and 3) the shoreline, describing the presence of shoreline structures for shore protection and recreational purposes.

York County Shoreline Management Plan, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox, Marcia Berman, Tamia Rudnicky, Karinna Nunez, Sharon Killeen

Reports

With approximately 85 percent of the Chesapeake Bay shoreline privately owned, a critical need existsto increase awareness of erosion potential and the choices available for shore stabilization that maintainecosystem services at the land-water interface. The National Academy of Science published a report thatspotlights the need to develop a shoreline management framework (NRC, 2007). It suggests that improv-ing awareness of the choices available for erosion control, considering cumulative consequences of erosion mitigation approaches, and improving shoreline management planning are key elements to minimizing adverse environmental impacts associated with mitigating shore erosion.

Students will participate in a role playing scenario in which they represent different stakeholder groups, including emergency responders, land planners, and watermen. Using a variety of provided resources, students are given a task to present on, whether it be creating an evacuation route for their county and identifying shelters, establishing new areas for development, or locations for the best catch of crabs in the year 2050.

Paradoxes Of Democratisation: Environmental Politics In East Asia, Mary Alice Haddad

Mary Alice Haddad

This chapter examines environmental politics in four polities that run the full spectrum of political regimes: mainland China (authoritarian), South Korea and Taiwan (newly democratic), and Japan (mature democracy). The chapter argues that variation in environmental politics in each place resulted primarily from the timing of their environmental movements, with subsequent movements learning from predecessors and gaining increasing access to global NGO networks. Paradoxically, when environmental movements became linked to democratization movements (in South Korea and Taiwan), they also became linked to political parties, which hindered access to government policymaking when non-allied parties were in power.

Worlds Without End: The Many Lives Of The Multiverse, Mary-Jane Rubenstein

Mary-Jane Rubenstein

Worlds without End explores the recent proliferation of "multiverse" cosmologies, which imagine our universe as just one of a vast, even infinite, number of others. While this idea has been the stuff of philosophy, religion, and literature for millennia, it is now under consideration as a scientific hypothesis, with wildly different models emerging from the fields of cosmology, quantum mechanics, and string theory. Beginning with the Atomistic and Stoic philosophies of ancient Greece, this book assembles a genealogy of the multiverse, seeking to map contemporary models in relation to their forerunners, and to ask why the proposition has become such …
