Dɛnkyɛm: Identity Development And Negotiation Among 1.5-Generation Ghanaian American Millennials, Jakia Marie

Open Access Publishing Support Funded Articles

Ghanaian immigrants are largely ignored in U.S.-based scholarship. Within this qualitative study, I explored the experiences of 1.5-generation Ghanaian American millennials with the purpose of understanding how they create, negotiate, and re-create identities. Using a phenomenological approach, I examined the experiences of eight individuals to specifically understand the creation and negotiation of national, ethnic, and racial identities in public and private spaces. I argue that the 1.5-generation is uniquely socially positioned and forced to code-switch and adapt based on age, race, and nationality, all while still learning to adjust to living in the U.S. The findings suggest that many individuals …

Seal Counting On Our Plages (S.C.O.O.P.), Kaanan Kharwa

Master's Theses

The Vertebrate Integrative Physiology (VIP) lab monitors the population of northern elephant seals at the largest mainland breeding colony, located at Piedras Blancas (San Simeon, CA). As the population expands, more human-seal interactions and conflicts over land use occur. The VIP lab's work informs California State Parks and helps with the management of the rookery. Currently, members of the VIP lab fly a drone over the beaches, capture multiple images, and manually count the seals, which takes around 14 to 21 hours of analysis per survey. Machine learning methods such as Convolutional Neural Networks (CNN) and Region-based Convolutional Neural Networks …

Technical Study And Conservation Treatment Of A Victorian-Era Taxidermy Bird Group, Daisy Greenwell

Art Conservation Master's Projects

During the Victorian era, taxidermy objects played the roles of educational tools, decoration, and personal adornment. The object at the center of this paper falls into the second category: decoration. It is a taxidermy bird life group, made up of six bird specimens, papier mâché rockwork, and dried plant material mounted on and around a faux tree armature. Owned by the Buffalo Museum of Science, it came to the Garman Art Conservation Department at Buffalo State University with no provenance record or attributions to a known maker. Two goals were developed at the onset of this project: to flesh out …

Influence Of Rearing Method On The Behaviour And Welfare Of Assaf Lambs During The Neonatal Period, Miroslav Simeonov, David L. Harmon, Ina Stoycheva

Animal and Food Sciences Faculty Publications

The present study aimed to determine the influence of rearing method on behaviour and welfare in Assaf lambs during the first two weeks of the neonatal period, in an intensive rearing system. The experiment was conducted with 24 Assaf lambs, in which two methods of management were applied – natural rearing (NR) and artificial rearing (AR). Forced separation of lambs from their mothers caused 74% fewer suckling attempts during the first three days of the neonatal period, which reduced suckling time by 57%. The lambs reared under NR, spent more time moving and less time standing and lying. Overall, it …

Corporate Participation In Social Debates, Anna Toniolo

The University of Chicago Business Law Review

Corporations are increasingly wading into social and political matters that are unrelated to their business operations. This Paper empirically investigates corporate participation in social debates through the corporate response to Dobbs, the Supreme Court’s decision overturning the constitutional right to abortion.

First, the Paper identifies and examines the public companies that reacted to the reversal of Roe v. Wade (“Reacting Companies”). Only a few corporations reacted. On the one side, they tend to be large, with sizeable workforces, concentrated in consumer-facing and tech industries, and headquartered in states with no restrictions on abortion rights. On the other side, they tend …

A New Strategy To Modify Hopfield By Using Xor Operation, Rusul Hussein Hasan

Baghdad Science Journal

The Hopfield network is one of the easiest types, and its architecture is such that each neuron in the network connects to the other, thus called a fully connected neural network. In addition, this type is considered auto-associative memory, because the network returns the pattern immediately upon recognition, this network has many limitations, including memory capacity, discrepancy, orthogonally between patterns, weight symmetry, and local minimum. This paper proposes a new strategy for designing Hopfield based on XOR operation; A new strategy is proposed to solve these limitations by suggesting a new algorithm in the Hopfield network design, this strategy will …

Neuroimaging Of The Effects Of Drug Exposure Or Self-Administration In Rodents: A Systematic Review, Gunner Drossel, Sarah R Heilbronner, Jan Zimmermann, Anna Zilverstand

Faculty, Staff and Students Publications

A systematic review of functional neuroimaging studies on drug (self-) administration in rodents is lacking. Here, we summarized effects of acute or chronic drug administration of various classes of drugs on brain function and determined consistency with human literature. We performed a systematic literature search and identified 125 studies on in vivo rodent resting-state functional magnetic resonance imaging (n = 84) or positron emission tomography (n = 41) spanning depressants (n = 27), opioids (n = 23), stimulants (n = 72), and cannabis (n = 3). Results primarily showed alterations in the striatum, consistent with the human literature. The anterior …

Preliminary Assessment Of Tunic Off-Gassing After Wildland Firefighting Exposure, Kiam Padamsey, Adelle Liebenberg, Ruth Wallace, Jacques Oosthuizen

Research outputs 2022 to 2026

Evidence has previously shown that outer tunics (turnout coats) worn by firefighters at structural fires are contaminated with harmful chemicals which subsequently off-gas from the material. However, there is limited research on whether this phenomenon extends to wildland firefighter uniforms. This pilot study aimed to explore if the tunics of volunteer bushfire and forestry firefighters in Western Australia off-gas any contaminants after exposure to prescribed burns or bushfires, and whether there is a need to explore this further. Nine tunics were collected from firefighters following nine bushfire and prescribed burn events, with a set of unused tunics serving as a …

A Framework For Modeling The Impacts Of Adaptive Search Intensity On The Efficiency Of Abundance Surveys., Laura Jiménez, John R Fieberg, Michael Mccartney, Jake M Ferguson

Biology Faculty Publications

When planning abundance surveys, the impact of search intensity on the quality of the density estimates is rarely considered. We constructed a time-budget modeling framework for abundance surveys using principles from optimal foraging theory. We link search intensity to the number of sample units surveyed, searcher detection probability, the number of detections made, and the precision of the estimated population density. This framework allowed us to determine how a searcher should behave to produce optimized density estimates. Using data collected from quadrat and removal surveys of zebra mussels (Dreissena polymorpha) in central Minnesota, we applied this framework to evaluate potential …

Identifying Key Environmental Drivers Of Reach-Scale Salmonid Edna Recovery With Random Forest, Shawn A. Melendy, John R. Olson

AES Faculty Publications and Presentations

Environmental DNA (eDNA) sampling from rivers has emerged as a promising new method for monitoring freshwater organisms of management concern. However, eDNA sampling cannot yet offer reliable estimates of a target species' abundance/biomass or confident determinations of a species' absence from a river segment. To unlock these abilities—and thereby greatly improve eDNA as a tool for management decision-making—the influence of local environmental factors on eDNA fate must be better understood. At nine river sites across the central California coast, we added a known quantity of novel eDNA (Brook Trout, Salvelinus fontinalis) and collected eDNA at sequential downstream distances for …

The Last Frontier: Fair Procedure In Informal Administrative Adjudication, Michael Asimow

Michigan Journal of Environmental & Administrative Law

The federal government engages in massive amounts of informal adjudication - a process that resolves a dispute between the government and a private party by making an individualized and legally binding decision without being required to conduct an evidentiary hearing if the dispute is not settled. This article sketches the highly diverse world of federal informal adjudication and surveys the procedural requirements imposed on it by due process and federal statutes. It proposes a set of best practices for conducting and improving informal adjudication that are rooted in those legal requirements. Agencies should adapt these practices to their individual circumstances …

From Columbus To Lansing: Exploring The Prosecution Of Environmental Crimes Within Epa Region 5, Joshua Ozymy, Melissa Jarrell Ozymy

Michigan Journal of Environmental & Administrative Law

Transgressions of federal environmental law involving significant harm or culpable conduct can result in criminal prosecution. However, we know very little about how such prosecutions have taken place within EPA Region 5, which includes Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin. We undertake a content analysis of 2,807 criminal prosecutions that resulted from U.S. EPA criminal investigations from 1983-2022, selecting all 392 prosecutions occurring within Region 5 for analysis. Results show that over $3.4 billion in monetary penalties, 1,039 years of probation, and over 492 years of incarceration were assessed at sentencing. 33 % of prosecutions centered on water pollution, …

Layered Visualization Of Argumentation Frameworks, Yilin Xia, Daphne Oderkerken, Shaun Bowers, Bertram Ludäscher

Computer Science Faculty Scholarship

We propose a new layered visualization in PyArg for grounded labelings of abstract argumentation frameworks. Argument nodes are colored according to their label (IN, OUT, or UNDEC) and have a new length annotation, which is derived from provenance subgraphs. New edge annotations explain an attack-edge’s role in determining the value (label) of nodes in an argumentation framework.

Chow, Sujoy Ghosh, Donald P. Mcdonnell, Paul M. Yen, Brijesh K. Singh

Division of Basic Science Faculty Publications

Objective: Currently, little is known about the mechanism(s) regulating global and specific protein translation during metabolic dysfunction-associated steatohepatitis (MASH; previously known as non-alcoholic steatohepatitis, NASH). Methods: Unbiased label-free quantitative proteome, puromycin-labelling and polysome profiling were used to understand protein translation activity in vitro and in vivo. Results: We observed a global decrease in protein translation during lipotoxicity in human primary hepatocytes, mouse hepatic AML12 cells, and livers from a dietary mouse model of MASH. Interestingly, proteomic analysis showed that Rplp1, which regulates ribosome and translation pathways, was one of the most downregulated proteins. Moreover, decreased Esrra expression and binding to …

Evaluating The Validity Of The Portionsize Smartphone Application For Estimating Dietary Intake In Free-Living Conditions: A Pilot Study, Hanim E. Diktas, Chloe P. Lozano, Sanjoy Saha, Stephanie T. Broyles, Corby K. Martin, John W. Apolzan

Clinical Research Faculty Publications

Objective: Evaluate the validity of the PortionSize application. Methods: In this pilot study, 14 adults used PortionSize to record their free-living food intake over 3 consecutive days. Digital photography was the criterion measure, and the main outcomes were estimated intake of food (grams), energy (kilocalories), and food groups. Equivalence tests with ±25% equivalence bounds and Bland-Altman analysis were performed. Results: Estimated gram intake from PortionSize was equivalent (P < 0.001) to digital photography estimates. PortionSize and digital photography estimated energy intake, however, were not equivalent (P = 0.08), with larger estimates from PortionSize. In addition, PortionSize and digital photography were equivalent for vegetable intake (P = 0.01), but PortionSize had larger estimates of fruits, grains, dairy, and protein intake (P >0.07; error range 11% to 23%). Conclusions and Implications: Compared with digital photography, PortionSize accurately estimated food intake and had reasonable error rates for other nutrients; however, it overestimated energy intake, indicating …

Far From Their Origins: A Transcriptomic Investigation On How 2,4-Di-Tert-Butyl-6-(5-Chloro-2h-Benzotriazol-2-Yl) Phenol Affects Rainbow Trout Alevins, Andreas N.M. Eriksson, Justin Dubiel, Alper James Alcaraz, Jon A. Doering, Steve Wiseman

Faculty Publications

Benzotriazole ultraviolet stabilizers (BUVSs) are a group of widely used chemicals added to a variety of consumer (e.g., plastics) and industrial (e.g., metal coating) goods. Although detected globally as an environmentally persistent pollutant, BUVSs have received relatively little toxicological attention and only recently have been acknowledged to affect development and the endocrine system in vivo. In our previous study, altered behavior, indicative of potential neurotoxicity, was observed among rainbow trout alevins (day 14 posthatching) that were microinjected as embryos with a single environmentally relevant dose of 2,4-di-tert-butyl–6-(5-chloro-2H-benzotriazol-2-yl) phenol (UV-327). In the present follow-up study, we performed whole-transcriptome profiling (RNA sequencing) …
