In For A Shock?: Discretion And Disparity In Program Assignment, Brianna Mathis Dec 2019

In For A Shock?: Discretion And Disparity In Program Assignment, Brianna Mathis

Honors Theses

Due to the massive prison population in America, correctional agencies are considering alternatives to standard incarceration. These programs are designed to redirect individuals from serving a prison sentence, and are instead assigned to a program specifically targeted at reducing offenders’ likelihood at recidivating. Typically, the main focus of these programs centers on education, job training, and various types of counseling. The Mississippi Department of Corrections (MDOC) has implemented two programs that aim at reducing recidivism: the first was the Regimented Inmate Discipline Program (RID), which was later replaced with the Recidivism Reduction Program (RRP). While both programs were intended to …

Genetic Diversity Of Blue Wildebeest (Connochaetes Taurinus) In The Liuwa Plain Of Zambia, Stephanie J. Szarmach Dec 2019

Genetic Diversity Of Blue Wildebeest (Connochaetes Taurinus) In The Liuwa Plain Of Zambia, Stephanie J. Szarmach

All NMU Master's Theses

Advances in DNA sequencing are enabling researchers to identify and genotype large sets of single nucleotide polymorphisms (SNPs) in non-model organisms to answer questions concerning ecology, evolution, and conservation. Analysis of SNP allele frequencies can provide insight into the amount of genetic diversity present in a population, connectivity between populations, and historical demographic changes. The blue wildebeest (Connochaetes taurinus) plays an important ecological role in many African savanna ecosystems, but little is known about the level of genetic diversity within most populations or the amount of gene flow that occurs between populations. In particular, the wildebeest in the …

Science And Risk Analysis In Cptpp/Sps-Plus: Role Model Or Unbearable Burden?, Kuei-Jung Ni

Journal of Food Law & Policy

Trade in food and agricultural products accounts for a major part of global trade, and the trade continues to alert domestic consumers to the risks associated with modern food processing and production methods. The Trans-Pacific Partnership Agreement (TPP), now rebranded as the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), represents a new model of mega-regional trade pacts posed to set higher standards for promoting and streamlining trade liberalization. Because of concerns with national food safety regulations that could constitute forms of non-tariff barriers, the CPTPP, in contrast to the World Trade Organization (WTO), stipulates further rules on parties’ sanitary …

Going Hemp Wild: Understanding The Challenges And Opportunities For Fda Regulation Of Cbd In Food Products, Hannah Catt Dec 2019

Going Hemp Wild: Understanding The Challenges And Opportunities For Fda Regulation Of Cbd In Food Products, Hannah Catt

Journal of Food Law & Policy

After the passage of the 2018 Farm Bill, champions of hemp began to tout opportunities for farmers and businesses involved with the crop. The industry has rallied around one of hemp’s major byproducts, cannabidiol, or CBD. However, the demand for CBD has left the Food and Drug Administration (“FDA”) playing catch-up. This article explains what CBD is, how it is derived, current FDA-approved uses, and a current path forward for the FDA in creating guidance for industry and consumers.

Δscope: A New Method To Quantify 3d Biological Structures And Identify Differences In Zebrafish Forebrain Development, Morgan S. Schwartz, Jake Schnabl, Mackenzie P.H. Litz, Benjamin Baumer, Michael Barresi

Biological Sciences: Faculty Publications

Research in the life sciences has traditionally relied on the analysis of clear morphological phenotypes, which are often revealed using increasingly powerful microscopy techniques analyzed as maximum intensity projections (MIPs). However, as biology turns towards the analysis of more subtle phenotypes, MIPs and qualitative approaches are failing to adequately describe these phenotypes. To address these limitations and quantitatively analyze the three-dimensional (3D) spatial relationships of biological structures, we developed the computational method and program called ∆SCOPE (Changes in Spatial Cylindrical Coordinate Orientation using PCA Examination). Our approach uses the fluorescent signal distribution within a 3D data set and reorients the …

The Concept Of The Hologenome, An Epigenetic Phenomenon, Challenges Aspects Of The Modern Evolutionary Synthesis, Adena Collens, Emma Kelley, Laura A. Katz Dec 2019

The Concept Of The Hologenome, An Epigenetic Phenomenon, Challenges Aspects Of The Modern Evolutionary Synthesis, Adena Collens, Emma Kelley, Laura A. Katz

Biological Sciences: Faculty Publications

John Tyler Bonner's call to re-evaluate evolutionary theory in light of major transitions in life on Earth (e.g., from the first origins of microbial life to the evolution of sex, and the origins of multicellularity) resonate with recent discoveries on epigenetics and the concept of the hologenome. Current studies of genome evolution often mistakenly focus only on the inheritance of DNA between parent and offspring. These are in line with the widely accepted Neo-Darwinian framework that pairs Mendelian genetics with an emphasis on natural selection as explanations for the evolution of biodiversity on Earth. Increasing evidence for widespread symbioses complicates …

© 2019, The Author(s). Incense burning is common worldwide and produces environmental toxicants that may influence health; however, biologic effects have been little studied. In 303 Emirati adults, we tested the hypothesis that incense use is linked to compositional changes in the oral microbiota that can be potentially significant for health. The oral microbiota was assessed by amplification of the bacterial 16S rRNA gene from mouthwash samples. Frequency of incense use was ascertained through a questionnaire and examined in relation to overall oral microbiota composition (PERMANOVA analysis), and to specific taxon abundances, by negative binomial generalized linear models. We found …

Pixel-Level Deep Multi-Dimensional Embeddings For Homogeneous Multiple Object Tracking, Mateusz Mittek Dec 2019

Pixel-Level Deep Multi-Dimensional Embeddings For Homogeneous Multiple Object Tracking, Mateusz Mittek

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

The goal of Multiple Object Tracking (MOT) is to locate multiple objects and keep track of their individual identities and trajectories given a sequence of (video) frames. A popular approach to MOT is tracking by detection consisting of two processing components: detection (identification of objects of interest in individual frames) and data association (connecting data from multiple frames). This work addresses the detection component by introducing a method based on semantic instance segmentation, i.e., assigning labels to all visible pixels such that they are unique among different instances. Modern tracking methods often built around Convolutional Neural Networks (CNNs) and additional, …

Genome-Wide Meta-Analysis Of Macronutrient Intake Of 91,114 European Ancestry Participants From The Cohorts For Heart And Aging Research In Genomic Epidemiology Consortium, Jordi Merino, Hassan S. Dashti, Sherly X. Li, Chloé Sarnowski, Anne E. Justice, Misa Graff, Constantina Papoutsakis, Caren E. Smith, George V. Dedoussis, John Blangero

School of Medicine Publications

Macronutrient intake, the proportion of calories consumed from carbohydrate, fat, and protein, is an important risk factor for metabolic diseases with significant familial aggregation. Previous studies have identified two genetic loci for macronutrient intake, but incomplete coverage of genetic variation and modest sample sizes have hindered the discovery of additional loci. Here, we expanded the genetic landscape of macronutrient intake, identifying 12 suggestively significant loci (P < 1 × 10-6) associated with intake of any macronutrient in 91,114 European ancestry participants. Four loci replicated and reached genome-wide significance in a combined meta-analysis including 123,659 European descent participants, unraveling two novel loci; a common variant in RARB locus for carbohydrate intake and a rare variant in DRAM1 locus for protein intake, and corroborating earlier FGF21 and FTO findings. In additional analysis of 144,770 participants from the UK Biobank, all identified associations from the two-stage analysis were confirmed except for DRAM1. Identified loci might have implications in brain and adipose tissue biology and have clinical impact in obesity-related phenotypes. Our findings provide new insight into biological functions related to macronutrient intake.

Time For Change: Stepping Up The Fda's Regulation Of Dietary Supplements To Promote Consumer Safety And Awareness, George Kennett Dec 2019

Time For Change: Stepping Up The Fda's Regulation Of Dietary Supplements To Promote Consumer Safety And Awareness, George Kennett

Journal of Law and Health

People are often looking for that quick fix when it comes to their health. With dietary supplements so readily available on the market, the public assume that they have been through rigorous testing. Dietary supplements are not tested as much as consumers believe. The Food and Drug Administration (FDA) does not initiate the same type of testing and analysis for supplements as it does for food, drink and medication. Given that people are now choosing supplemental meal replacements and the like, as opposed to whole foods, regulations drastically need to be stepped up in an effort to emphasise public safety. …

The Examination Of The Function Of The Cofactor Schnurri In The Cyst Stem Cells Of The Drosophila Melanogaster Testis Niche, Jade Koretko Dec 2019

The Examination Of The Function Of The Cofactor Schnurri In The Cyst Stem Cells Of The Drosophila Melanogaster Testis Niche, Jade Koretko

Master's Theses

The study of adult stem cells in modern day research provides pertinent information about the development of organisms, how they grow, and how tissue is maintained. Drosophila melanogaster provide an ideal model for in vivo stem cell research, with one of the best-characterized niches in the testis. The testis stem cell niche consists of a hub that provides signals to the local stem cells, germline stem cells (GSCs), and cyst stem cells (CySCs). The CySCs produce cyst cell lineage that will provide support for the GSC daughter cells, which differentiate into sperm. Previously, Matunis, et al. determined the function of …

A Description Of Lichen Community Structure And The Impacts Of Spruce Beetle Disturbance In Northwestern Colorado, Anna Freundlich Dec 2019

A Description Of Lichen Community Structure And The Impacts Of Spruce Beetle Disturbance In Northwestern Colorado, Anna Freundlich

Master's Theses

Spruce beetle disturbance has affected millions of acres of forest throughout North America and Europe, but thus far little research has investigated how this disturbance influences lichen communities. To address this problem, we studied lichen communities and habitat characteristics within 44 plots across a chronosequence of spruce beetle damage spanning 1996–2017 in northwestern Colorado. We found 82 species of lichens, few habitat differences among spruce beetle disturbance classes, and only the most recently affected plots (2012–2017) had significantly different lichen community structure relative to remaining areas. Two primary gradients explained the majority of variation of lichen community structure within our …

Queering Fertility: Experiences Of Queer/Lesbian People Undergoing Fertility Treatment In A Heteronormative Society, Caitlin Ortis Dec 2019

Queering Fertility: Experiences Of Queer/Lesbian People Undergoing Fertility Treatment In A Heteronormative Society, Caitlin Ortis

Master's Theses

Due to the increase in lesbian, gay, bisexual, transgender, queer, and other (+) (LGBTQ+) people seeking fertility treatments or the “Lesbian Baby Boom” (Amato & Jacob, 2004; Batza, 2016; Dunne, 2000; Simon et al., 1993; Mamo, 2013), in which 30% to 50% of women who identify as lesbians hope to become parents (Amato & Jacob, 2004), it is necessary to examine the relationship between a person’s sexual orientation and her experiences receiving fertility treatments. While fertility treatment from a heterosexual perspective has been studied at length, few studies have examined how LGBTQ+ people are treated in fertility clinic settings. In …

Characterizing The Role Of Tumor Suppressors Merlin And Expanded In The Stem Cell Niche Of Drosophila Testes, Bryan Johnson Dec 2019

Characterizing The Role Of Tumor Suppressors Merlin And Expanded In The Stem Cell Niche Of Drosophila Testes, Bryan Johnson

Master's Theses

The ability of adult organisms to maintain tissue homeostasis and repair tissue in response to injury is mediated by small groups of partially differentiated cells called adult stem cells that support the tissue they reside in. Adult stem cell maintenance is highly regulated by signals from the surrounding microenvironment referred to as the stem cell niche. A better understanding of this process will have important implications for the fields of both regenerative medicine and cancer biology. Due to the complexity of most niche environments in mammals, we turned to the less complex model organism Drosophila and the well-characterized niche in …

Characterizing The Susceptibility And Type I Interferon Response Of Primary Mammalian Cells During Zika Virus Infection, Douglas Petty

Master's Theses

Zika virus (ZIKV), a member of the genus Flavivirus, has become a major public health concern since 2007. During the most recent 2015 outbreak, ZIKV rapidly spread from South America to over 84 countries and territories across the world in two years. ZIKV has also been associated with previously uncharacterized neurological manifestations during the 2013 and 2015 outbreaks. The novel manifestations include Guillain-Barré Syndrome (GBS) in adults and Congenital Zika Syndrome (CZS) in newborns. GBS is a progressive paralysis caused by damage to the peripheral nervous system; while CZS is an all-encompassing term for the severe neurological and developmental complications …

School of Medicine Publications

Sustained inflammation and matrix metalloproteinase (MMP) activation contribute to vascular occlusive/proliferative disorders. Interleukin-17 (IL-17) is a proinflammatory cytokine that signals mainly via TRAF3 Interacting Protein 2 (TRAF3IP2), an upstream regulator of various critical transcription factors, including AP-1 and NF-κB. Reversion inducing cysteine rich protein with kazal motifs (RECK) is a membrane-anchored MMP inhibitor. Here we investigated whether IL-17A/TRAF3IP2 signaling promotes MMP-13-dependent human aortic smooth muscle cell (SMC) proliferation and migration, and determined whether RECK overexpression blunts these responses. Indeed, IL-17A treatment induced (a) JNK, p38 MAPK, AP-1, NF-κB, and CREB activation, (b) miR-21 induction, (c) miR-27b and miR-320 inhibition, (d) …

Childhood Witnessing Of Domestic Violence And Its Impact On Character Development Across Time And Adulthood Relationships, Zena Ouzounian Dec 2019

Childhood Witnessing Of Domestic Violence And Its Impact On Character Development Across Time And Adulthood Relationships, Zena Ouzounian

Antioch University Dissertations & Theses

This phenomenological research study explored the experiences of five adult participants who reported witnessing domestic violence between their parents during childhood. Through the process of open-ended interviews, this work added further support to the existing understanding of the impact that childhood witnessing of parental violence can have on one’s adult behavior and relationships. Thus far, child witnesses to parental violence receive little attention, perhaps due to the lack of tangible evidence that they have been harmed. Existing studies in the field primarily make use of quantitative methods to examine negative outcomes of such experiences. This study identified similar themes among …

Development And Characterization Of A Biopolymer Direct-Write Process For 3d Microvascular Structures Formation., Xiaoming Fan Dec 2019

Development And Characterization Of A Biopolymer Direct-Write Process For 3d Microvascular Structures Formation., Xiaoming Fan

Electronic Theses and Dissertations

Engineering of bulk tissues has been limited by the lack of nutrient and waste exchange in these tissues without an adjacent capillary network. To produce microvasculature, a scaffold must be produced that provides temporary mechanical support and stimulate endothelial cell adhesion, growth, and morphogenesis into a vessel. However, current well-established techniques for producing microvasculature, such as electrospinning, are limited since they lack both the precision to control fiber placement in three-dimensional space and the ability to create fiber networks with predefined diameters to replicate the physiological microvascular progression from arteriole to capillary to venule. Our group has developed a “Direct-write” …

Towards A Theory Of Human Mobility And Wall-Building: A Comparative Analysis Of Hadrian's Wall And The Iron Curtain., Timothy Heine Dec 2019

Towards A Theory Of Human Mobility And Wall-Building: A Comparative Analysis Of Hadrian's Wall And The Iron Curtain., Timothy Heine

Electronic Theses and Dissertations

This thesis contributes a theory on human bordering practices that encompasses diverse types of borders and border experiences. In order to flesh out the factors underlying human wall-building, it is vital to first understand the mobile nature (both as an innate characteristic and adaptive strategy) of our species. A clearer appreciation of the biology of human mobility elucidates the seemingly counterintuitive process of the establishment of cultural boundaries. Such an inquiry into the available inter-disciplinary literature on the topics of human mobility and wall-building reveals much about the manner in which humans interpret and utilize space, the variety of walls …
