Work Ethic Skills And A Liberal Arts Education: Using Work-Integrated Learning In A Liberal Arts Course To Enhance Students' Work Ethic Skills And Demonstrate The Practicality Of A Liberal Arts Education., Jennifer M. Lopes

Theses and Dissertations

To address the gap in employability skills among recent college graduates, the proposed intervention seeks to integrate work ethic skills (WES) into the general education curriculum in a practical, efficient, and effective way to develop and enhance students’ professional skills. Work-integrated learning (WIL), if done properly, is the most effective method for students to learn, practice, and apply professional and academic skills. Problematic is the fact that general education courses have tenuous WIL connections because they are not “job specific. Hence, Kolb’s (1984) experiential learning theory is applied as the theoretical framework for creating effective an meaningful learning experiences via …


Application And Evaluation Of Full-Field Surrogate Models In Engineering Design Space Exploration, Christopher Murray Thelin Jul 2019

Application And Evaluation Of Full-Field Surrogate Models In Engineering Design Space Exploration, Christopher Murray Thelin

Theses and Dissertations

When designing an engineering part, better decisions are made by exploring the entire space of design variations. This design space exploration (DSE) may be accomplished manually or via optimization. In engineering, evaluating a design during DSE often consists of running expensive simulations, such as finite element analysis (FEA) in order to understand the structural response to design changes. The computational cost of these simulations can make thorough DSE infeasible, and only a relatively small subset of the designs are explored. Surrogate models have been used to make cheap predictions of certain simulation results. Commonly, these models only predict single values …

Biofilms are surface-associated microbial communities known for their increased resistance to antimicrobials and host factors. This resistance introduces a critical clinical challenge, particularly in cases associated with implants increasing the predisposition for bacterial infections. Preventing such infections requires the development of novel antimicrobials or compounds that enhance bactericidal effect of currently available antibiotics. We have synthesized and characterized twelve novel silver(I) cyanoximates designated as Ag(ACO), Ag(BCO), Ag(CCO), Ag(ECO), Ag(PiCO), Ag(PICO) (yellow and red polymorphs), Ag(BIHCO), Ag(BIMCO), Ag(BOCO), Ag(BTCO), Ag(MCO) and Ag(PiPCO). The compounds exhibit a remarkable resistance to high intensity visible light, UV radiation and heat and have poor solubility …

Neuroendocrine Markers Insulinoma-Associated Protein 1, Chromogranin, Synaptophysin, And Cd56 Show Rare Positivity In Adenocarcinoma Ex-Goblet Cell Carcinoids, Chen Yang, Ivan Gonzalez, Lingxin Zhang, Dengfeng Cao

Open Access Publications

Background: Adenocarcinoma ex-goblet cell carcinoid (AdexGCC) was considered a neuroendocrine adenocarcinoma, despite majority of tumor cells being negative for conventional neuroendocrine markers such as chromogranin and synaptophysin. Recently, insulinoma-associated protein 1 (INSM1) has been identified as a novel neuroendocrine marker that is more sensitive than chromogranin, synaptophysin, and CD56 in pulmonary neuroendocrine tumors.

Methods: We studied this marker in conjunction with chromogranin, synaptophysin, and CD56 in 36 appendiceal AdexGCCs (21 primaries, 15 metastatic).

Results: Primary AdexGCCs showed staining for INSM1, chromogranin, synaptophysin, and CD56 in 13/21 (62%), 18/21 (86%), 18/21 (86%), and 9/19 (47%) cases, respectively. However, the mean proportion …


The Generation Of Novel Metal-Folate- Phenanthroline Complexes And Phenanthroline-Folate Conjugates With Potential As Chemotherapeutic Agents, Aisling Crowley Jun 2019

The Generation Of Novel Metal-Folate- Phenanthroline Complexes And Phenanthroline-Folate Conjugates With Potential As Chemotherapeutic Agents, Aisling Crowley

Doctoral

The folate receptor (FR) was identified in 1986 and has been established as a ‘molecular Trojan Horse’ target for the uptake of folate-conjugated organic molecules into cells. The FR is overexpressed in many malignancies, including those of the ovary, uterus, breast, cervix, and prostate, yet it is reportedly under-expressed in normal healthy cells. This difference in expression and the high affinity/specificity of folate towards the folate receptor presents a promising drug delivery system. The aim of this research was to utilise folic acid as a targeting moiety and generate simple metal folate and novel folate-phenanthroline complexes with cytotoxic properties. A …

Review Of Grosphus Simon, 1880, With Description Of Teruelius Gen. N., A New Buthid Genus From Madagascar (Scorpiones: Buthidae), Graeme Lowe, František Kovařík

Euscorpius

We review the taxonomy of the Madagascar endemic buthid genus Grosphus Simon, 1880. We split the genus and describe Teruelius gen. n. on the basis of nine morphological characters, six of them new for Grosphus: positions of trichobothria d2 on pedipalp femur and Eb3 on chela manus, number of pectine teeth, shape of female basal pectinal tooth, form of hemispermatophore capsule posterior lobe, spiracle shape, metasoma I ventromedian carination, telotarsal setation and UV fluorescence. We discuss functional and taxonomic aspects of these characters, and propose that Teruelius gen. n. is monophyletic, while Grosphus (sensu stricto) is paraphyletic. …

Gemtuzumab-ozogamicin (GO), a humanized-anti-CD33 antibody linked with the toxin-calicheamicin-γ is a reemerging and promising drug for AML. Calicheamicin a key element of GO, induces DNA-damage and cell-death once the linked CD33-antibody facilitates its uptake. Calicheamicin efflux by the drug-transporter PgP-1 have been implicated in GO response thus in this study, we evaluated impact of ABCB1-SNPs on GO response. Genomic-DNA samples from 942 patients randomized to receive standard therapy with or without addition of GO (COG-AAML0531) were genotyped for ABCB1-SNPs. Our most interesting results show that for rs1045642, patients with minor-T-allele (CT/TT) had better outcome as compared to patients with CC …

Play Behavior And The Development Of Boldness And Caution In Juvenile Belding’S Ground Squirrels (Urocitellus Beldingi), Madelene Shehan

Master's Theses

The ubiquity of play among juvenile mammals suggests it provides adaptive benefits, potentially through influences on the development of temperament in young animals. Juvenile Belding’s ground squirrels (Urocitellus beldingi) must balance competing demands for boldness and caution imposed by the fundamental trade-off between their short active season and their vulnerability to predation. In this study, I evaluated whether play helps to facilitate the development of an appropriate balance between boldness and caution in juvenile U. beldingi.I observed the play behavior of juvenile U. beldingiand conducted flight-initiation distance tests to measure boldness-caution at the beginning and toward …

Fusion peptides (FPs) in spike proteins are key players mediating early events in cell-to-cell fusion, vital for intercellular viral spread. A proline residue located at the central FP region has often been suggested to have a distinctive role in this fusion event. The spike glycoprotein from strain RSA59 (PP) of mouse hepatitis virus (MHV) contains two central, consecutive prolines in the FP. Here, we report that deletion of one of these proline residues, resulting in RSA59 (P), significantly affected neural cell syncytia formation and viral titers postinfection in vitro. Transcranial inoculation of C57Bl/6 mice with RSA59 (PP) or RSA59 (P) …

Utilization of these devices for cellular fluorescence imaging is also possible, paving the way for more sophisticated methods of dynamic assessment. Herein, we fabricated a pre-designed microfluidic device from photolithography, containing microwells capable of immobilizing human …


The Evolutionary And Functional Roles Of Synonymous Codon Usage In Eukaryotes, Zhen Peng May 2019

The Evolutionary And Functional Roles Of Synonymous Codon Usage In Eukaryotes, Zhen Peng

Arts & Sciences Graduate Student Theses and Dissertations

Most amino acids are encoded by multiple synonymous codons. Although alternative usage of synonymous codons does not affect the amino acid sequences of proteins, researchers have been reporting evidence for functional synonymous codon usage at the species- and gene-specific levels for over four decades. It has been shown that variations in synonymous codon usage can affect phenotypes through diverse mechanisms such as shaping translation efficiency and mRNA stability. On the other hand, the common view that cellular and organismal phenotypes are primarily determined by proteins whose functions are primarily determined by amino acid sequences, often drives the assumption that synonymous …

The rise of inexpensive, user-friendly cameras and editing software promises to revolutionize data collection with minimal disturbance to marine mammals. Video sequences recorded by aerial drones and GoPro cameras provided close-up views and unique perspectives of humpback whales engulfing juvenile salmon at or just below the water surface in Southeast Alaska and Prince William Sound. Although humpback feeding is famous for its flexibility, several stereotyped events were noted in the 47 lunges we analyzed. Engulfment was extremely rapid (mean 2.07 s), and the entrance through which the tongue inverts into the ventral pouch was seen as water rushes in. Cranial …
