University Faculty Publications and Creative Works

Collection of biological samples for DNA is necessary in a variety of disciplines including disease epidemiology, landscape genetics, and forensics. Quantity and quality of DNA varies depending on the method of collection or media available for collection (e.g., blood, tissue, fecal). Blood is the most common sample collected in vials or on Whatman Flinders Technology Associates (FTA) cards with short- and long-term storage providing adequate DNA for study objectives. The focus of this study was to determine if biological samples stored on Whatman FTA Elute cards were a reasonable alternative to traditional DNA sample collection, storage, and extraction. Tissue, nasal …

Labor's New Localism, Andrew Elmore

Faculty Scholarship

Millions of workers in the United States, disproportionately women, immigrants, and people of color, perform low-paid, precarious work. Few of these workers can improve their workplace standards because the National Labor Relations Act ("NLRA") does not sufficiently protect their right to form unions and collectively bargain. Lacking sufficient influence in federal and state government to strengthen labor and employment law, unions and worker centers have increasingly sought to build power in cities. The shift to local labor lawmaking has delivered local minimum wage, paid sick leave, and fair scheduling ordinances covering millions of low-wage workers, as well as groundbreaking unionization …

Organizational Culture: An Examination Of The Role Of Leadership In Neutralizing The Negative Effects Of Technostress During Operational Shifts, David P. Kirkland

All-Inclusive List of Electronic Theses and Dissertations

COVID-19 created a support problem for public universities across the United States and required that IT departments and professionals alter how they performed in 2020, and perhaps beyond. IT professionals tasked with safeguarding large amounts of data were required to shift to a teleworking posture to continue offering a similar level of service as previously expected. In addition to the technological shift that organizations experienced because of COVID-19, leadership challenges also impacted IT departments across the United States. The rapid shift of operational duties has the propensity to increase technology-related stress, due to employee perception of being successful in their …

Spatial Proximity Matters: A Study On Collaboration, Arianna Salazar Miranda, Matthew Claudel

Geography Faculty Publications and Presentations

As scientific research becomes increasingly cross-disciplinary, many universities seek to support collaborative activity through new buildings and institutions. This study examines the impacts of spatial proximity on collaboration at MIT from 2005 to 2015. By exploiting a shift in the location of researchers due to building renovations, we evaluate how discrete changes in physical proximity affect the likelihood that researchers co-author. The findings suggest that moving researchers into the same building increases their propensity to collaborate, with the effect plateauing five years after the move. The effects are large when compared to the average rate of collaboration among pairs of …

For Fall 2021 Art & Social Practice History at Portland State University, I explored the social simulation game Animal Crossing: New Horizons (ACNH) as a digital altar. I asked How do social simulation games provide a dream space, a neighborhood btwn IRL and URL relationships? How is online gardening similar to sanctuary making, altar making? My co-conspirators offered me Fuck Tom Nook. In other words, should we build an altar in a capitalist, escapist, and colonialist dystopia? This project …

Timber Constructed: Towards An Alternative Material History, Laila Seewang, Irina Davidovici

School of Architecture Faculty Publication and Presentations

Editorial:

This issue of Architectural Theory Review proposes an alternative intellectual history of timber architecture. It foregrounds the relationships that tie the natural resource to the cultural artefact, its processing into construction material and, with it, the production of associated disciplinary expertise. The essays explore the spatial and symbolic possibilities of timber in historical and contemporary discourse by highlighting its simultaneity as cultural artefact, material commodity, environmental resource, and structural element. Thus, the material’s appearance and representation are positioned within perennial oscillations between globalism and locality, natural and man-made, industry and craft, innovation and tradition, material and ideology, modernity and …

A Practical Extension To The Ab/Ba Design, My T.A Nguyen

Electronic Theses and Dissertations

In this work, we take a close look at a general extension to the traditional AB/BA
crossover design that is commonly used in clinical trials to determine the effectiveness
of new candidate drugs. While the traditional crossover design requires each patient
in the study to be measured on both treatment A and treatment B, we consider the
possibility of additional measurements being available on each patient. This produces
designs such as the AABB/BBAA design which has been used in previous studies.
A general test statistic will be derived to test for treatment effects as well as its
corresponding power function …

Soil Gypsum Content Analysis Of The Proposed Road Route Extension Of Fm 2185 In The Gypsum Plain, Culberson County, Texas, Chikaodili Ohakawa

Electronic Theses and Dissertations

Soils serve as the underlying substrate on which foundations for most structures are built. The properties of a soil type are therefore an important consideration in building engineered structures. Gypsic soils are problematic for construction of such structures. One of the main problems with gypsic soils is dissolution. Gypsum (CaSO₄·2H₂O) in soils dissolves easily creating voids which can be detrimental to the integrity of engineering structures. To mitigate this, it is important to determine the amount of gypsum present in soils, before construction is initiated.

In this study, three methods were employed in the determination of …

Widening Spinal Injury Research To Consider All Supraspinal Cell Types: Why We Must And How We Can, Murray G. Blackmore, Eliazbeth Batsel, Pantelis Tsoulfas

Biomedical Sciences Faculty Research and Publications

The supraspinal connectome consists of dozens of neuronal populations that project axons from the brain to the spinal cord to influence a wide range of motor, autonomic, and sensory functions. The complexity and wide distribution of supraspinal neurons present significant technical challenges, leading most spinal cord injury research to focus on a handful of major pathways such as the corticospinal, rubrospinal, and raphespinal. Much less is known about many additional populations that carry information to modulate or compensate for these main pathways, or which carry pre-autonomic and other information of high value to individuals with spinal injury. A confluence of …

The Preconstruction Of Foundation For A Greenhouse, Alla I. Hashim

Construction Management

This project outlines the preconstruction process for building a concrete base for a prefabricated greenhouse unit. This project was initiated by the Cal Poly Garden Club so they could plan for the installation of a greenhouse at the Student Experimental Farm on Cal Poly’s campus. The members of the club currently share a greenhouse with another Cal Poly Club which restricts their ability to use the greenhouse freely. The initial goal of the project was to request a permit, however, that will be postponed until the specific location is determined. This project still provides the necessary elements for requesting a …

A Safety Factor Approach To Designing Urban Infrastructure For Dynamic Conditions, Sanjib Sharma, Ben Seiyon Lee, Robert E. Nicholas, Klaus Keller

Dartmouth Scholarship

Current approaches to design flood-sensitive infrastructure typically assume a stationary rainfall distribution and neglect many uncertainties. These assumptions are inconsistent with observations that suggest intensifying extreme precipitation events and the uncertainties surrounding projections of the coupled natural-human systems. Here we demonstrate a safety factor approach to designing urban infrastructure in a changing climate. Our results show that assuming climate stationarity and neglecting deep uncertainties can drastically underestimate flood risks and lead to poor infrastructure design choices. We find that climate uncertainty dominates the socioeconomic and engineering uncertainties that impact the hydraulic reliability in stormwater drainage systems. We quantify the upfront …

Γδ T Cell Ifnγ Production Is Directly Subverted By Yersinia Pseudotuberculosis Outer Protein Yopj In Mice And Humans, Timothy H. Chu, Camille Khairallah, Jason Shieh, Rhea Cho, Zhijuan Qiu, Yue Zhang, Onur Eskiocak, David G. Thanassi, Mark H. Kaplan, Semir Beyaz, Vincent W. Yang, James B. Bliska, Brian S. Sheridan

Dartmouth Scholarship

Yersinia pseudotuberculosis is a foodborne pathogen that subverts immune function by translocation of Yersinia outer protein (Yop) effectors into host cells. As adaptive γδ T cells protect the intestinal mucosa from pathogen invasion, we assessed whether Y. pseudotuberculosis subverts these cells in mice and humans. Tracking Yop translocation revealed that the preferential delivery of Yop effectors directly into murine Vγ4 and human Vδ2+ T cells inhibited anti-microbial IFNγ production. Subversion was mediated by the adhesin YadA, injectisome component YopB, and translocated YopJ effector. A broad anti-pathogen gene signature and STAT4 phosphorylation levels were inhibited by translocated YopJ. Thus, Y. pseudotuberculosis …

Associations Between Postpartum Depression And Assistance With Household Tasks And Childcare During The Covid-19 Pandemic: Evidence From American Mothers, Theresa E. Gildner, Glorieuse Uwizeye, Rebecca L. Milner, Grace C. Alston, Zaneta M. Thayer

Dartmouth Scholarship

Background: The early postpartum period is recognized cross-culturally as being important for recovery, with new parents receiving increased levels of community support. However, COVID-19-related lockdown measures may have disrupted these support systems, with possible implications for mental health. Here, we use a cross-sectional analysis among individuals who gave birth at different stages of the pandemic to test (i) if instrumental support access in the form of help with household tasks, newborn care, and care for older children has varied temporally across the pandemic, and (ii) whether access to these forms of instrumental support is associated with lower postpartum depression scores. …

Integrating Satellite, Uav, And Ground-Based Remote Sensing In Archaeology: An Exploration Of Pre-Modern Land Use In Northeastern Iraq, Elise Jakoby Laugier, Jesse Casana

Dartmouth Scholarship

Satellite remote sensing is well demonstrated to be a powerful tool for investigating ancient land use in Southwest Asia. However, few regional studies have systematically integrated satellite-based observations with more intensive remote sensing technologies, such as drone-deployed multispectral sensors and ground-based geophysics, to explore off-site areas. Here, we integrate remote sensing data from a variety of sources and scales including historic aerial photographs, modern satellite imagery, drone-deployed sensors, and ground-based geophysics to explore pre-modern land use along the Upper Diyala/Sirwan River in the Kurdistan Region of Iraq. Our analysis reveals an incredible diversity of land use features, including canals, qanats, …

Dartmouth Scholarship

Background: Indices obtained from lymph node dissection specimens, specifically lymph node yield (LNY) and lymph node ratio (LNR), have prognostic significance in the setting of head and neck squamous cell carcinoma (HNSCCa). However, there are currently no validated tools to estimate adequacy of planned lymph node dissection using preoperative data. The present study sought to evaluate CT-derived estimates of lymphatic tissue volumes as a preoperative tool to guide cervical node dissection. Methods: Fifteen cervical lymph node dissections were performed in 14 subjects with HNSCCa. Preoperative CT-derived estimates of lymphatic tissue volumes were compared with gross pathology tissue volume estimates and …

A Distributed Fmri-Based Signature For The Subjective Experience Of Fear, Feng Zhou, Weihua Zhao, Ziyu Qi, Yayuan Geng, Shuxia Yao, Keith M. Kendrick, Tor D. Wager, Benjamin Becker

Dartmouth Scholarship

The specific neural systems underlying the subjective feeling of fear are debated in affective neuroscience. Here, we combine functional MRI with machine learning to identify and evaluate a sensitive and generalizable neural signature predictive of the momentary self-reported subjective fear experience across discovery (n = 67), validation (n = 20) and generalization (n = 31) cohorts. We systematically demonstrate that accurate fear prediction crucially requires distributed brain systems, with important contributions from cortical (e.g., prefrontal, midcingulate and insular cortices) and subcortical (e.g., thalamus, periaqueductal gray, basal forebrain and amygdala) regions. We further demonstrate that the neural representation of subjective fear …

Spectral Analysis Of Climate Dynamics With Operator-Theoretic Approaches, Gary Froyland, Dimitrios Giannakis, Benjamin R. Lintner, Maxwell Pike, Joanna Slawinska

Dartmouth Scholarship

The Earth’s climate system is a classical example of a multiscale, multiphysics dynamical system with an extremely large number of active degrees of freedom, exhibiting variability on scales ranging from micrometers and seconds in cloud microphysics, to thousands of kilometers and centuries in ocean dynamics. Yet, despite this dynamical complexity, climate dynamics is known to exhibit coherent modes of variability. A primary example is the El Niño Southern Oscillation (ENSO), the dominant mode of interannual (3–5 yr) variability in the climate system. The objective and robust characterization of this and other important phenomena presents a long-standing challenge in Earth system …

Color Cherenkov Imaging Of Clinical Radiation Therapy, Daniel A. Alexander, Anthony Nomezine, Lesley A. Jarvis, David J. Gladstone, Brian W. Pogue, Petr Bruza

Dartmouth Scholarship

Color vision is used throughout medicine to interpret the health and status of tissue. Ionizing radiation used in radiation therapy produces broadband white light inside tissue through the Cherenkov effect, and this light is attenuated by tissue features as it leaves the body. In this study, a novel time-gated three-channel camera was developed for the first time and was used to image color Cherenkov emission coming from patients during treatment. The spectral content was interpreted by comparison with imaging calibrated tissue phantoms. Color shades of Cherenkov emission in radiotherapy can be used to interpret tissue blood volume, oxygen saturation and …

Developing Diagnostic Assessment Of Breast Lumpectomy Tissues Using Radiomic And Optical Signatures, Samuel S. Streeter, Brady Hunt, Rebecca A. Zuurbier, Wendy A. Wells, Keith D. Paulsen, Brian W. Pogue

Dartmouth Scholarship

High positive margin rates in oncologic breast-conserving surgery are a pressing clinical problem. Volumetric X-ray scanning is emerging as a powerful ex vivo specimen imaging technique for analyzing resection margins, but X-rays lack contrast between non-malignant and malignant fibrous tissues. In this study, combined micro-CT and wide-field optical image radiomics were developed to classify malignancy of breast cancer tissues, demonstrating that X-ray/optical radiomics improve malignancy classification. Ninety-two standardized features were extracted from co-registered micro-CT and optical spatial frequency domain imaging samples extracted from 54 breast tumors exhibiting seven tissue subtypes confirmed by microscopic histological analysis. Multimodal feature sets improved classification …

Diverse Antiviral Igg Effector Activities Are Predicted By Unique Biophysical Antibody Features, Hao D. Cheng, Karen G. Dowell, Chris Bailey-Kellogg, Brittany A. Goods, J. Christopher Love, Guido Ferrari, Galit Alter, Johannes Gach, Donald N. Forthal, George K. Lewis, Kelli Greene, Hongmei Gao, David C. Montefiori, Margaret E. Ackerman

Dartmouth Scholarship

Background: The critical role of antibody Fc-mediated effector functions in immune defense has been widely reported in various viral infections. These effector functions confer cellular responses through engagement with innate immune cells. The precise mechanism(s) by which immunoglobulin G (IgG) Fc domain and cognate receptors may afford protection are poorly understood, however, in the context of HIV/SHIV infections. Many different in vitro assays have been developed and utilized to measure effector functions, but the extent to which these assays capture distinct antibody activities has not been fully elucidated. Results: In this study, six Fc-mediated effector function assays and two biophysical …
