Sexism And Severity: An Examination Of Teacher's Attitudes About Autism Symptomology In The Classroom, Kaitlyn Niederstadt Dec 2021

Sexism And Severity: An Examination Of Teacher's Attitudes About Autism Symptomology In The Classroom, Kaitlyn Niederstadt

Psychology and Counseling Theses

Girls continue to be underdiagnosed and under-researched in the study of autism spectrum disorder (ASD). This is the result of a systemized preference towards masculine symptomology of ASD examined and created to diagnose ASD. The ideas produced by the research trickle down to teachers who then are in charge of flagging students for signs of ASD, however this step is not only limited by understanding, but their own inherent gender biases on behaviors. Our sample consisted of 139 current or former teachers. Each participant received one of three, (varying from severity levels and gender), rating scale of behavior association, rating …


Modeling A Human Family Network, Rebecca Jo Flores Dec 2021

Modeling A Human Family Network, Rebecca Jo Flores

Theses and Dissertations

We propose a model that generates a family network based on real-world family network data. We use this model to study the extent to which distances to union and the number of children characterize family networks. To determine how accurate our model is we use persistent homology to identify and compare the structure of our modeled family networks to real-world family networks. To accomplish this, we introduce the notion of a network's persistence curve, which encodes the network's set of persistence intervals. Using the bottleneck distance allows us to measure the difference in the homological structure between any pair of …

Time-Resolved Cryo-Em Visualizes Ribosomal Translocation With Ef-G And Gtp, Christine E Carbone, Anna B Loveland, Howard Gamper, Ya-Ming Hou, Gabriel Demo, Andrei A Korostelev Dec 2021

Time-Resolved Cryo-Em Visualizes Ribosomal Translocation With Ef-G And Gtp, Christine E Carbone, Anna B Loveland, Howard Gamper, Ya-Ming Hou, Gabriel Demo, Andrei A Korostelev

Department of Biochemistry and Molecular Biology Faculty Papers

During translation, a conserved GTPase elongation factor-EF-G in bacteria or eEF2 in eukaryotes-translocates tRNA and mRNA through the ribosome. EF-G has been proposed to act as a flexible motor that propels tRNA and mRNA movement, as a rigid pawl that biases unidirectional translocation resulting from ribosome rearrangements, or by various combinations of motor- and pawl-like mechanisms. Using time-resolved cryo-EM, we visualized GTP-catalyzed translocation without inhibitors, capturing elusive structures of ribosome•EF-G intermediates at near-atomic resolution. Prior to translocation, EF-G binds near peptidyl-tRNA, while the rotated 30S subunit stabilizes the EF-G GTPase center. Reverse 30S rotation releases Pi and translocates peptidyl-tRNA and …

No One Told Me What Infertility Would Be Like For A Black Man. That's Because Nobody Knows., Keith "Jared" Wright, Zachary Smith Dec 2021

No One Told Me What Infertility Would Be Like For A Black Man. That's Because Nobody Knows., Keith "Jared" Wright, Zachary Smith

Capstones

I am a 34-year-old, 6-foot-3 Black man who weighed over 330 pounds. In navigating my infertility journey, I noticed a major disparity in donors throughout sperm banks all over the country. Additionally, I noticed that while male infertility is rarely discussed in general, it is significantly more suppressed in Black and Brown communities. An open dialogue and more transparency can hopefully ensure that those suffering from this condition can have an easier road in their journey than their predecessors.

Peroxisomal Β-Oxidation Acts As A Sensor For Intracellular Fatty Acids And Regulates Lipolysis, Lianggong Ding, Wenfei Sun, Miroslav Balaz, Anyuan He, Manuel Klug, Stefan Wieland, Robert Caiazzo, Violeta Raverdy, Francois Pattou, Philippe Lefebvre, Irfan J Lodhi, Bart Staels, Markus Heim, Christian Wolfrum

Open Access Publications

To liberate fatty acids (FAs) from intracellular stores, lipolysis is regulated by the activity of the lipases adipose triglyceride lipase (ATGL), hormone-sensitive lipase and monoacylglycerol lipase. Excessive FA release as a result of uncontrolled lipolysis results in lipotoxicity, which can in turn promote the progression of metabolic disorders. However, whether cells can directly sense FAs to maintain cellular lipid homeostasis is unknown. Here we report a sensing mechanism for cellular FAs based on peroxisomal degradation of FAs and coupled with reactive oxygen species (ROS) production, which in turn regulates FA release by modulating lipolysis. Changes in ROS levels are sensed …


Mercury Emissions From Iron Mining And Copper Mining In The Upper Peninsula, Michigan, Ahmed Al Rahbi Dec 2021

Mercury Emissions From Iron Mining And Copper Mining In The Upper Peninsula, Michigan, Ahmed Al Rahbi

Honors Theses

The wealth in the Upper Peninsula of Michigan has been intimately linked with mining, particularly the extraction of iron and copper. Iron was deposited in the Upper Peninsula 1.9 billion years ago (Gogebic and Ranges, 2020), and copper deposits are believed to be 1.1 billion years old (Blakemore et al., 2016). In the Upper Peninsula, mercury occurs naturally in taconite (iron ore) as elemental mercury (Hg0), and within the copper ores as “Mercury copper amalgam” (CuHg). When elemental mercury is released from the ores, it oxidizes in the atmosphere to form inorganic mercury (Hg2+) (Risher, 2003; …

School of Biological and Marine Sciences

The impacts of artificial light at night (ALAN) on marine ecosystems have emerged as a focus for ecological light pollution research in recent years, yet the global prevalence of ALAN in underwater marine ecosystems is unknown. We have derived a global atlas of ALAN throughout the marine water column that will accelerate our understanding of its sources and environmental impacts. At a depth of 1 m, 1.9 million km2 of the world’s coastal seas are exposed to biologically important ALAN, which equates to around 3.1% of the global exclusive economic zones. This area decreases to 1.6 million km2 (2.7%) at …

Comparison Of Quality And Production By Different Silage Making Methods Of Barley Cultivated In The Paddy After Rice Harvest, J. S. Shin, E. B. Yoon, M. S. Park

IGC Proceedings (1977-2023)

The objective of this study was to compare whether the productivity and production cost of whole crop barley was affected by silage making methods at early bloom stage in the rice field. In nutritive value, quality and palatability of silage, baled silage making method was a little higher than that of crushed silage making. On the other hand, in terms of dry matter and total digestible nutrient (TDN) production cost, proper work capacity at about 15 ha or more was desirable when making baled silage. In this case, the estimated dry matter production cost and TDN cost per ha was …

Mental Health In Italy: Systems, Stigma, And Impact Of Covid-19, Charley Nyzio Dec 2021

Mental Health In Italy: Systems, Stigma, And Impact Of Covid-19, Charley Nyzio

CISLA Senior Integrative Projects

In 1978, Italy became the first European nation to radically change its mental healthcare system. Psychiatric hospitals were shut down, and a community-based publicly-funded system of mental healthcare took its place. This reform sought to restore dignity to those with mental illnesses through rehabilitation and increased participation in the community and daily activities. Though characteristics of marginalization and exclusion were relatively eliminated, covert stigmas surrounding mental illness remain a persisting problem. This review seeks to 1) evaluate the historical progression of mental health reform as well as the effectiveness of the current system of mental healthcare in Italy 2) explore …

Given the growing issue in healthcare of antibiotic resistance, effective and safe alternative treatment methods are required. One of these possible alternative treatment methods is bacteriotoxins including bacteriocins and tailocins. The focus of this study is a bacteriotoxin from Burkholderia cenocepacia (ATCC 25608), which was induced for toxin using a modified UV light induction procedure and tested against a variety of Pseudomonas and Burkholderia for its killing capacity. Various other pathogenic strains were then induced with UV light and tested. The results showed that the toxin from ATCC 25608 was very effective against most of the Burkholderia tested and warrants …


Sex- And Age - Specific Migratory Strategies Of Blue Whales In The Northeast Pacific, Christina Blevins Dec 2021

Sex- And Age - Specific Migratory Strategies Of Blue Whales In The Northeast Pacific, Christina Blevins

Biology ETDs

Sequential subsampling of blue whale baleen plates can yield information of individual migratory plasticity of this endangered species in the northeast Pacific Ocean. We measured δ13C and δ15N isotope values along baleen from thirteen whales of different age and sex. Results showed sex/age-specific migratory strategies. Adult females exhibited relatively stable cyclical movements between temperate and subtropical regions. Adult males exhibited two strategies, most remained within temperate latitudes, whereas two migrated to subtropical latitudes. Movement patterns in juveniles were erratic. These patterns are potentially driven by energetic requirements of females, intraspecific competitions among adult males, and inexperience in locating prey in …

Importance Of Optometric Practices, Nikhita Jacob Dec 2021

Importance Of Optometric Practices, Nikhita Jacob

Honors Projects

This research examines what effect education has on people’s decision-making. More specifically, whether better education leads to better decisions and health outcomes, and why that is important for optometry. Every decision someone makes depends on some type of information, whether it is heard, read about, watched, or experienced. The more information someone has, the more confident someone can be in the decisions they make. Access to information and to education, whether it is through school, libraries, or news channels, is not always equal. It is important that people are informed about subjects as important as their health, by those who …

Understanding Coralline Algal Responses To Ocean Acidification: Meta‐Analysis And Synthesis, Ce Cornwall, Ben P. Harvey, Steeve Comeau, Dl Cornwall, Jason Hall‐Spencer, Viviana Peña, Shigeki Wada, Lucia Porzio

School of Biological and Marine Sciences

Ocean acidification (OA) is a major threat to the persistence of biogenic reefs throughout the world's ocean. Coralline algae are comprised of high magnesium calcite and have long been considered one of the most susceptible taxa to the negative impacts of OA. We summarize these impacts and explore the causes of variability in coralline algal responses using a review/qualitative assessment of all relevant literature, meta-analysis, quantitative assessment of critical responses, and a discussion of physiological mechanisms and directions for future research. We find that most coralline algae experienced reduced abundance, calcification rates, recruitment rates, and declines in pH within the …
