Experience Of Nontenured, Tenure-Track Faculty And Gatekeeping: A Qualitative Research Study, Meghan Butler

Dissertations (1934 -)

Using a consensual qualitative research (CQR) approach, this study investigated the experience of nontenured, tenure track faculty (NTTTF) members involved in gatekeeping with students for non-academic concerns from American Psychological Association (APA)- and The Council for the Accreditation of Counseling and Related Educational Programs (CACREP)-accredited programs. The study investigated the emotional and cognitive reactions, factors supportive/facilitative and discouraging/hindering of the decision to intervene, the impact the gatekeeping process had on NTTTF relationships and what the NTTTF learned from the gatekeeping intervention. Participants were five female faculty members. Results indicated participants had little to no training in gatekeeping beyond informal training …

Hegel And The Problem Of The Multiplicity Of Conflicting Philosophies, Matthew M. Peters

Dissertations (1934 -)

As Hegel notes in his long Introduction to the Lectures on the History of Philosophy, the problem of the multiplicity of conflicting philosophies presents a particularly urgent problem to the very discipline of philosophy itself. For, from the viewpoint of what Hegel would refer to as “ordinary consciousness”, the fact that there are so many different philosophies which seem constantly to disagree can only lead to one conclusion: philosophy itself is a futile enterprise. Hegel, perhaps more than any previous philosopher, was sensitive to this charge of futility levelled against philosophy. In response, he provided an explanatory account of the …

The Neural Encoding Of Reward In The Striatal-Pallidal Circuitry, Chung Lung Chan

Dissertations (1934 -)

Humans and animals are constantly exposed to external stimuli. The ability to process reward value of a stimulus is critical to guiding appropriate behavior and essential for survival. These processes are regulated by neuronal activity and neurochemical signaling in the reward circuitry, particularly in the nucleus accumbens (NAc). The NAc receives dopaminergic inputs from the midbrain ventral tegmental area (VTA) and sends GABAergic projections to the ventral pallidum (VP). Electrophysiological studies have characterized phasic neuronal responses in the NAc that differential encode appetitive and aversive taste stimuli. Exposure to an appetitive taste stimulus evoked predominantly phasic inhibitory responses in the …

The Impact Of Racial Miscategorization And Racial Ambiguity On Multiracial Identity And Well-Being: A Qualitative Study, Shirley A. Newcomb

Dissertations (1934 -)

Despite the rapid growth of the multiracial population there is a dearth of literature that informs the field of counseling psychology about the identity development and well-being of multiracial people. More specifically, there is little research which explores the challenge of having one’s racial identity repeatedly questioned and/or miscategorized, and how these experiences of racial miscategorization and racial incongruence may influence their identity choices and well-being. The sample consisted of 11 total participants, (women N = 9, men N = 2) who self-identified as racially ambiguous and of multiracial descent. Overall findings of the study suggest that experiences of racial …

The Noncanonical Roles Of Two Primordial Molecules In Flagella, Xiaoyan Zhu

Dissertations (1934 -)

Motile cilia and flagella are ancient organelles that eukaryotic organisms today still rely on to thrive in their natural environment. Not surprisingly, accumulated evidence has shown that the intricate motility machinery, the microtubule-based axoneme, is evolutionarily conserved down to the molecular level. This notion is epitomized by the signature axonemal complex, the radial spoke (RS). The RS is part of a control center conferring the high frequency and tightly regulated movement. Key RS proteins discovered in biflagellate green alga, Chlamydomonas reinhardtii, are also generated by nearly all ciliated organisms, including Homo sapiens. Among them are two subunits from primordial protein …

Functional Analysis Of Microrna Pathway Genes In The Somatic Gonad And Germ Cells During Ovulation In C. Elegans, Carmela Rios

Dissertations (1934 -)

MicroRNAs (miRNAs) are post-­transcriptional regulators of gene expression that play critical roles in animal development and physiology, though functions for most miRNAs remain unknown. Worms with reduced miRNA biogenesis due to loss of Drosha or Pasha/DGCR8 activity are sterile and fail to ovulate, indicating that miRNAs are required for the process of oocyte maturation and ovulation. Starting with this penetrant sterile phenotype and using new strains created to perform tissue-­specific RNAi, we characterize the roles of the C. elegans Pasha, pash-­1, and two miRNA-­specific Argonautes, alg-­1 and alg-­2, in somatic gonad cells and in germ cells in the regulation of …

Functional And Structural Studies Of Cytochromes P450 By Resonance Raman Spectroscopy, Yilin Liu

Dissertations (1934 -)

Cytochrome P450 is a broad class of heme monooxygenase enzymes which catalyze various oxidative transformations. There are two main kinds of mammalian P450s: steroidogenic and drug metabolizing P450s. The first project involves a steroidogenic P450, CYP17A1, occupying a central role in the biosynthesis of steroid hormones. It catalyzes hydroxylation reaction on pregnenolone and progesterone, generating 17OH-pregnenolone and 17OH-progesterone, presumably utilizing a “Compound I” species. However, these hydroxylated products can be further processed in a second oxidative cycle to cleave the C17–C20 bond to form dehydroepiandrosterone or androstenedione, respectively, a crucial step in androgen production. Interestingly, it is well known that …

The Development And Psychometric Analysis Of The Mu- Fertility Knowledge Assessment Scale, Qiyan Mu

Dissertations (1934 -)

Young women between the ages of 18 to 24 experience disproportionally high rates of negative sexual and reproductive health outcomes. Inadequate and inaccurate fertility knowledge can hinder a young woman’s self-care abilities in managing her sexual and reproductive health. There is no validated instrument to assess young women’s fertility knowledge. The primary purpose of this study is to develop and evaluate the psychometric properties of the MU-fertility knowledge assessment scale (MU-FKAS) for young women. The secondary purpose is to explore the relationships among young women’s individual and contextual factors, self-perceived fertility knowledge, actual fertility knowledge, and fertility health risks. A …

Appropriation Without Benefit-Sharing: Origin-Of-Resource Disclosure Requirements And Enforcement Under Trips And The Nagoya Protocol, Wallace Feng

Chicago Journal of International Law

Since the late twentieth century, there have been many instances of foreign entities appropriating a country’s biological resources without sharing with that country the benefits of its patents that are associated with those resources. This appropriation without benefit-sharing (AWBS) has led to calls that patent applicants should disclose the geographical origins of biological resources used in their inventions in order for patent offices to better assess the patentability of these inventions. This Comment investigates whether international law mandates disclosure and whether there can be an effective system to enforce disclosure by focusing on two treaties: the Agreement on Trade-Related Aspects …

Articles, Abstracts, and Reports

Although several lung cancer susceptibility loci have been identified, much of the heritability for lung cancer remains unexplained. Here 14,803 cases and 12,262 controls of European descent were genotyped on the OncoArray and combined with existing data for an aggregated genome-wide association study (GWAS) analysis of lung cancer in 29,266 cases and 56,450 controls. We identified 18 susceptibility loci achieving genome-wide significance, including 10 new loci. The new loci highlight the striking heterogeneity in genetic susceptibility across the histological subtypes of lung cancer, with four loci associated with lung cancer overall and six loci associated with lung adenocarcinoma.

Tumor-Treating Fields Plus Chemotherapy Versus Chemotherapy Alone For Glioblastoma At First Recurrence: A Post Hoc Analysis Of The Ef-14 Trial., Santosh Kesari, Zvi Ram

Articles, Abstracts, and Reports

BACKGROUND: This post hoc analysis of the EF-14 trial (NCT00916409) of tumor-treating fields (TTFields) plus temozolomide versus temozolomide alone in newly diagnosed glioblastoma compared the efficacy of TTFields plus chemotherapy (physician's choice) versus chemotherapy alone after first recurrence.

METHODS: Patients on TTFields plus temozolomide continued TTFields plus second-line chemotherapy after first recurrence. Some patients on temozolomide alone crossed over after approval of TTFields for recurrent GBM. The primary efficacy outcome was overall survival (OS).

RESULTS: After disease progression, 131 patients received TTFields plus chemotherapy and 73 chemotherapy alone. Thirteen patients in the original temozolomide-alone group crossed over to receive TTFields …

The Rhoj-Bad Signaling Network: An Achilles' Heel For Braf Mutant Melanomas., Rolando Ruiz, Sohail Jahid, Melissa Harris, Diego M Marzese, Francisco Espitia, Priya Vasudeva, Chi-Fen Chen, Sebastien De Feraudy, Jie Wu, Daniel L Gillen, Tatiana B Krasieva, Bruce J Tromberg, William J Pavan, Dave S B Hoon, Anand K Ganesan

Articles, Abstracts, and Reports

Genes and pathways that allow cells to cope with oncogene-induced stress represent selective cancer therapeutic targets that remain largely undiscovered. In this study, we identify a RhoJ signaling pathway that is a selective therapeutic target for BRAF mutant cells. RhoJ deletion in BRAF mutant melanocytes modulates the expression of the pro-apoptotic protein BAD as well as genes involved in cellular metabolism, impairing nevus formation, cellular transformation, and metastasis. Short-term treatment of nascent melanoma tumors with PAK inhibitors that block RhoJ signaling halts the growth of BRAF mutant melanoma tumors in vivo and induces apoptosis in melanoma cells in vitro via …

Fundamental Studies And Applications Of Ambient Plasma Ionization Sources For Mass Spectrometry, Wade C. Ellis

Theses and Dissertations

The field of ambient desorption/ionization mass spectrometry (ADI-MS) has existed for over a decade. ADI-MS is a technique that offers benefits including fast analysis time, simple ionization sources that are easily constructed, and little to no required sample preparation. The research presented here describes efforts to better understand plasma-based ADI-MS sources and to explore the use of hydrogen-doped plasma gases with these sources. The use of hydrogen-doped argon (H₂/Ar) and hydrogen-doped helium (H₂/He) as plasma gases for a dielectric barrier discharge (DBD) and an AC glow discharge is presented first. When using the DBD, the intensity …

Nanosecond Electric Pulses Differentially Affect Inward And Outward Currents In Patch Clamped Adrenal Chromaffin Cells, Lisha Yang, Gale L. Craviso, P. Thomas Vernier, Indira Chatterjee, Normand Leblanc

Bioelectrics Publications

This study examined the effect of 5 ns electric pulses on macroscopic ionic currents in whole-cell voltage-clamped adrenal chromaffin cells. Current-voltage (I-V) relationships first established that the early peak inward current was primarily composed of a fast voltage-dependent Na⁺ current (I_Na), whereas the late outward current was composed of at least three ionic currents: a voltage-gated Ca²⁺ current (I_Ca), a Ca²⁺-activated K⁺ current (I_K(Ca)), and a sustained voltage-dependent delayed rectifier K⁺ current (I_KV). A constant-voltage step protocol was next used to monitor peak inward and late …

Divergence Of Camp Signalling Pathways Mediating Augmented Nucleotide Excision Repair And Pigment Induction In Melanocytes, Erin M. Wolf Horrell, Stuart G. Jarrett, Katharine M. Carter, John A. D'Orazio

Markey Cancer Center Faculty Publications

Loss‐of‐function melanocortin 1 receptor (MC1R) polymorphisms are common in UV‐sensitive fair‐skinned individuals and are associated with blunted cAMP second messenger signalling and higher lifetime risk of melanoma because of diminished ability of melanocytes to cope with UV damage. cAMP signalling positions melanocytes to resist UV injury by upregulating synthesis of UV‐blocking eumelanin pigment and by enhancing the repair of UV‐induced DNA damage. cAMP enhances melanocyte nucleotide excision repair (NER), the genome maintenance pathway responsible for the removal of mutagenic UV photolesions, through cAMP‐activated protein kinase (protein kinase A)‐mediated phosphorylation of the ataxia telangiectasia‐mutated and Rad3‐related (ATR) protein on the S435 …

Abundance And Distribution Of Microbial Cells And Viruses In An Alluvial Aquifer, Donald Pan, Jason Nolan, Kenneth H. Williams, Karrie A. Weber

School of Biological Sciences: Faculty Publications

Viruses are the most abundant biological entity on Earth and their interactions with microbial communities are recognized to influence microbial ecology and impact biogeochemical cycling in various ecosystems. While the factors that control the distribution of viruses in surface aquatic environments are well-characterized, the abundance and distribution of continental subsurface viruses with respect to microbial abundance and biogeochemical parameters have not yet been established. In order to begin to understand the factors governing virus distribution in subsurface environments, we assessed microbial cell and virus abundance in groundwater concurrent with groundwater chemistry in a uranium impacted alluvial aquifer adjoining the Colorado …

How Question Types Reveal Student Thinking: An Experimental Comparison Of Multiple-True-False And Free-Response Formats, Joanna K. Hubbard, Macy A. Potts, Brian A. Couch

School of Biological Sciences: Faculty Publications

Assessments represent an important component of undergraduate courses because they affect how students interact with course content and gauge student achievement of course objectives. To make decisions on assessment design, instructors must understand the affordances and limitations of available question formats. Here, we use a crossover experimental design to identify differences in how multiple-true-false (MTF) and free-response (FR) exam questions reveal student thinking regarding specific conceptions. We report that correct response rates correlate across the two formats but that a higher percentage of students provide correct responses for MTF questions. We find that MTF questions reveal a high prevalence of …

Population-Level Coordination Of Pigment Response In Individual Cyanobacterial Cells Under Altered Nitrogen Levels, Jaclyn Murton, Aparna Nagarajan, Amelia Y. Nguyen, Michelle Liberton, Harmony A. Hancock, Himadri B. Pakrasi, Jerilyn A. Timlin

Biological Sciences Faculty Publications

Cyanobacterial phycobilisome (PBS) pigment-protein complexes harvest light and transfer the energy to reaction centers. Previous ensemble studies have shown that cyanobacteria respond to changes in nutrient availability by modifying the structure of PBS complexes, but this process has not been visualized for individual pigments at the single-cell level due to spectral overlap. We characterized the response of four key photosynthetic pigments to nitrogen depletion and repletion at the subcellular level in individual, live Synechocystis sp. PCC 6803 cells using hyperspectral confocal fluorescence microscopy and multivariate image analysis. Our results revealed that PBS degradation and re-synthesis comprise a rapid response to …

Inhibition Of Histone Methyltransferase, Histone Deacetylase, And Beta-Catenin Synergistically Enhance The Cardiac Potential Of Bone Marrow Cells, J Yang, Kanika Kaur, John G. Edwards, Carol Eisenberg, Leonard Eisenberg

NYMC Faculty Publications

Previously, we reported that treatment with the G9a histone methyltransferase inhibitor BIX01294 causes bone marrow mesenchymal stem cells (MSCs) to exhibit a cardiocompetent phenotype, as indicated by the induction of the precardiac markers Mesp1 and brachyury. Here, we report that combining the histone deacetylase inhibitor trichostatin A (TSA) with BIX01294 synergistically enhances MSC cardiogenesis. Although TSA by itself had no effect on cardiac gene expression, coaddition of TSA to MSC cultures enhanced BIX01294-induced levels of Mesp1 and brachyury expression 5.6- and 7.2-fold. Moreover, MSCs exposed to the cardiogenic stimulus Wnt11 generated 2.6- to 5.6-fold higher levels of the cardiomyocyte markers …

Analysis Of The Proposed Tpp-Related Patent Linkage System In Taiwan, Ping-Hsun Chen

Journal of Law and Health

The Trans-Pacific Partnership (TPP) Agreement mandates member states to implement a patent linkage system vested in Article 18.53. To successfully join the TPP Agreement, Taiwan has begun the legislation of a patent linkage system by proposing an amendment for the Pharmaceutical Affairs Act. Article 18.53 requires a member either to adopt a notification mechanism under Paragraph 1 or to stay the issuance of marketing approval under Paragraph 2. But, Taiwan’s proposal includes both measures. Taiwan’s patent linkage system allows a pioneer drug company to register patents claiming (a) a material, (b) a combination or formula, or (c) pharmaceutical use. The …

Weird Science: Frankenstein Foods And States As Laboratories Of Democracy, Jennifer Mcgee

Journal of Law and Health

The National Bioengineered Food Disclosure Standard (the 'National Standard') was signed into law July 29, 2016. This Article analyzes the National Standard and posits that Vermont’s Act 120 was a more effective labeling law because it safeguarded consumer sovereignty. The State regulatory scheme in place prior to the passage of the National Standard satisfied consumer demand for disclosure while allowing for necessary experimentation with GMO labeling. Part I provides an overview of the current federal scheme regulating GMOs. Part II analyzes of the conflict surrounding GMOs and labeling. Given that analysis, Part III compares the disclosure requirement of the National …

Liberal-Democratic States Should Privilege Parental Efforts To Instill Identities And Values, Andrew M. Robinson

Political Science Faculty Publications

Liberal-democratic states’ commitments to equality and personal autonomy have always proven problematic with respect to state regulation of relations between parents and children. In the parental authority literature positions have varied from invoking children’s interests to argue for limitations on parental efforts to instill identities and values to invoking parental rights to justify state privileging of such efforts.

This article argues that liberal-democratic states should privilege parental efforts to raise their children to share their identities and values. Its approach is distinctive in two ways: i) it engages in interdisciplinary reflection upon selected findings in psychological literature on immigrant youth, …

Can Ecosystem Functional Recovery Be Traced To Decomposition And Nitrogen Dynamics In Estuaries Of The Lower Laguna Madre, Texas?, Mario A. Marquez, Alejandro Fierro-Cabo, Carlos E. Cintra-Buenrostro

School of Earth, Environmental, & Marine Sciences Faculty Publications

The biggest incentive to attempt the restoration and protection of estuaries is their widely acknowledged ecological and economic importance. Assessing estuary health and recovery can most accurately come from examining ecosystem processes. The purpose of this study was to explore the potential of mass loss and nitrogen (N) dynamics during leaf litter decomposition, to detect signs of functional recovery in two estuarine systems in south Texas. Submerged litterbags with black mangrove (Avicennia germinans) leaves were retrieved at various dates over 320 days. Decomposition was about 50% slower in one of the recovering systems compared to a reference site. …

School of Earth, Environmental, & Marine Sciences Faculty Publications

A Rancieite type material (K2Mn4O9) nanomaterial was synthesized and tested for the removal of chromium (III) and chromium (VI) from aqueous solutions. The synthesized nanomaterial was characterized using powder XRD and SEM. XRD showed weak diffraction peaks at only at the angles associated with K2Mn4O9. The SEM corroborated that the nanoparticles were present; however, the nanoparticles were clustered into larger aggregates. Batch studies were performed to determine the optimum pH, capacity, time dependency, interferences, and the thermodynamics of the binding. The optimum pH for the binding of Cr(III) and Cr(VI) were determined to be pH 5 and pH 2, respectively. …
