Star Formation In Low-Redshift Cluster Dwarf Galaxies, Cody M. Rude, Madina R. Sultanova, Gihan L. Ipita Kaduwa Gamage, Wayne A. Barkhouse, Sandanuwan P. Kalawila Vithanage

Physics Faculty Publications

Evolution of galaxies in dense environments can be affected by close encounters with neighbouring galaxies and interactions with the intracluster medium. Dwarf galaxies (dGs) are important as their low mass makes them more susceptible to these effects than giant systems. Combined luminosity functions (LFs) in the r and u band of 15 galaxy clusters were constructed using archival data from the Canada–France–Hawaii Telescope. LFs were measured as a function of clustercentric radius from stacked cluster data. Marginal evidence was found for an increase in the faint-end slope of the u-band LF relative to the r-band with increasing clustercentric …

We report the discovery of two ultra-faint stellar systems found in early data from the DECam Local Volume Exploration survey (DELVE). The first system, Centaurus I (DELVE J1238–4054), is identified as a resolved overdensity of old and metal-poor stars with a heliocentric distance of , a half-light radius of , an age of , a metallicity of , and an absolute magnitude of . This characterization is consistent with the population of ultra-faint satellites and confirmation of this system would make Centaurus I one of the brightest recently discovered ultra-faint dwarf galaxies. Centaurus I is detected in Gaia DR2 with …

Alzheimer's disease (AD) displays a long asymptomatic stage before dementia. We characterize AD stage-associated molecular networks by profiling 14,513 proteins and 34,173 phosphosites in the human brain with mass spectrometry, highlighting 173 protein changes in 17 pathways. The altered proteins are validated in two independent cohorts, showing partial RNA dependency. Comparisons of brain tissue and cerebrospinal fluid proteomes reveal biomarker candidates. Combining with 5xFAD mouse analysis, we determine 15 Aβ-correlated proteins (e.g., MDK, NTN1, SMOC1, SLIT2, and HTRA1). 5xFAD shows a proteomic signature similar to symptomatic AD but exhibits activation of autophagy and interferon response and lacks human-specific deleterious events, …

Emotional Responses To A Sexual Assault Threat: A Qualitative Analysis Among Women With Histories Of Sexual Victimization, Kristin E. Silver, Raeann E. Anderson, Amanda M. Brouwer

Psychology Faculty Publications

Sexual assaults against women are a leading threat to human rights and public health in the United States. Considering the high rates of sexual revictimization among women and the limited understanding of the mechanisms which fuel this phenomenon, the goal of the present study was to investigate the role of emotion in coping with a hypothetical threat of sexual assault for previously sexually victimized college women. A total of 114 college women with a history of sexual victimization listened to an audio-recording describing a sexual assault scenario and then described how they felt. A qualitative analysis paradigm was used to …

An Exploration Of Correctional Counselor Workloads In A Midwestern State, Adam K. Matz, Nathan C. Lowe

Criminal Justice Faculty Publications

Time studies have been conducted with a variety of occupations. However, no known research has examined the workload of correctional counselors. The Iowa Department of Corrections, in partnership with the American Probation and Parole Association, performed the first known workload evaluation of this population. Over a hundred correctional counselors participated in a time study informed by a task analysis conducted with a representative advisory committee. The most common activities concerned inmate requests, classification, assessment, release planning, treatment group work, and administrative tasks. Most concerning, respondents indicated anywhere from 20-to-50% of the activities engaged in were unsatisfactorily completed.

Fluid Identity Play: A Case Study Of A Bilingual Child’S Ethnic Identity Construction Across Multiple Contexts, Hyonsuk Cho, X. Christine Wang

Teaching, Leadership & Professional Practice Faculty Publications

Informed by positioning theory as well as a nexus of multimembership, the year-long case study examined how a 7-year-old Korean American bilingual child, Meeso, constructed her ethnic identity across different educational contexts. Data were collected through observations of Meeso’s interactions with her monolingual and bilingual peers and teachers. Discourse analysis revealed that Meeso constructed fluid ethnic identity positionings depending upon how she desired to position herself and to be positioned by others. We also identified that the social context, language proficiency, and peer dynamics were related to the process. Based on the findings, we discuss the roles of context, language, …

Deep Direct Use Geothermal Energy In The North Dakota Clean Energy Transition Strategy, Al Thibeault, Moones Alamooti, Nnaemeka Ngobidi, Will Gosnold

Geology and Geological Engineering Faculty Publications

The geothermal heat in the Williston Basin is an energy giant that can provide sustainable, renewable, and ecologically sound heat and power for the state of North Dakota (ND). We have known of this resource for decades, but development has been delayed for reasons which can be summed as economic competition from existing fossil fuel energy sources. With the “seismic” shock of the Covid-19 pandemic reverberating through the state’s carbon-centric economy, the timing is ideal for acting quickly to develop this energy resource.

Coincidentally, the State Energy Research Center (SERC) within the Energy & Environmental Research Center (EERC), has recently …
