Money Matters To All Students, George Padilla, Michelle H. Abrego

i.e.: inquiry in education

The question whether money matters in education strikes at the foundation of America’s democracy—an educated electorate. Despite decades of evidence that money does matter, the question still remains unanswered among many and even answered to the contrary of the evidence. It is important to fully understand that money does matter in American education, American lives, and America’s future and to increase awareness of political and social factors that undermine that money matters for all students to learn.

Prison Bars & Bird Cages: Conducting An Arts-Based Participatory Research Project With Undergraduate Women In Stem, Batsheva Guy, Tziporah Feldman

i.e.: inquiry in education

The ‘chilly’ STEM climate in undergraduate settings has been widely documented, as women in STEM majors frequently face discrimination, microaggressions, and implicit bias from their professors and peers. While undergraduate research opportunities can help women in STEM overcome some of the barriers they face, these opportunities are not always accessible and inclusive. Although there is a breadth of literature on this topic, many studies utilize traditional quantitative and qualitative methods and do not take the authentic, individualized voices of these women into account. The present study integrates two arts-based, participatory methodologies-- Photovoice and Collage Inquiry-- in order to explore the …

Through conducting a focus group discussion, and …

Preference Conflict And Peace Studies: The Line Between Disagreement And Violence, Frederic R. Kellogg

Peace and Conflict Studies

Broadening the definition of conflict defines more comprehensively the condition of peace, focusing on how unresolved shared disagreements can lead to, or avoid, polarization and violence. The line between general disagreement and violent conflict lies in the adjustment of shared preferences. Matters like reproductive rights, medically assisted death, race and gender discrimination, while subject to political polarization, are open to peaceful redress through what John Dewey called the transformative continuum of inquiry, in which the crucial social response to shared problems includes dispute and conflict. Resolution of controversial social problems requires preference adjustment and habit change, often, if not always, …

Consciousness And The Reality Of Monsters In Horror Movies: Dehumanization And What Monsters In Horror Films Say About Us, Leila Kincaid

Journal of Conscious Evolution

This essay responds to Carroll’s The Nature of Horror from the perspective of transdisciplinary phenomenological film theory, largely developed by Edgar Morin in the 1950s. It argues that Carrolls’s reduction of the phenomenological value of horror films to an unreal category minimizes and even dismisses the inherent value of horror films. Morin, Allan Combs, and others offer more integral and transdisciplinary methods for art interpretation and functionality. They help us understand how monsters in horror films can stand as mirrors and reflections of the monstrous in ourselves and society. Thus, the transformational function and value of film is revealed and …

Stochastic 1-D Reactive Transport Simulations To Assess Silica And Carbonate Phases During The Co2 Reinjection Process In Metasediments, Selçuk Erol

Turkish Journal of Earth Sciences

One proposed method to mitigate carbon emission is to mineralize the CO2 in deep geothermal reservoirs while mixing the coproduced CO2 with the effluent fluid for reinjection. The injection fluid temperature fluctuates due to the mixing process between CO2-charged water and the effluent fluid, and compressor interruptions change the thermodynamic conditions that influence the fluid-rock interaction in the reservoir. Mineral dissolution or precipitations are associated with changes in permeability and porosity that affect the flow and, eventually, the lifespan of the reservoir. A combined stochastic–reactive transport simulation approach is useful for inspection purposes. Moreover, the stochastic algorithm validates the deterministic …

T-Cell Redirecting Bispecific Antibodies: A Review Of A Novel Class Of Immuno-Oncology For Advanced Prostate Cancer, Julia Palecki, Amman Bhasin, Andrew Bernstein, Patrick Mille, William Tester, William Kelly, Kevin Zarrabi

Kimmel Cancer Center Faculty Papers

Novel T-cell immunotherapies such as bispecific T-cell engagers (BiTEs) are emerging as promising therapeutic strategies for prostate cancer. BiTEs are engineered bispecific antibodies containing two distinct binding domains that allow for concurrent binding to tumor-associated antigens (TAAs) as well as immune effector cells, thus promoting an immune response against cancer cells. Prostate cancer is rich in tumor associated antigens such as, but not limited to, PSMA, PSCA, hK2, and STEAP1 and there is strong biologic rationale for employment of T-cell redirecting BiTEs within the prostate cancer disease space. Early generation BiTE constructs employed in clinical study have demonstrated meaningful antitumor …

A Rising Tide That Lifts All Boats: Long-Term Effects Of The Alaska Permanent Fund Dividend On Poverty, Matthew Berman

ISER Articles

Although not designed as a social program to redistribute income, the Alaska Permanent Fund Dividend (PFD) has been reducing poverty by providing equal annual payments to nearly all state residents for over 40 years. We examine direct effects of the PFD on Alaska poverty rates since 1990, using US Census and American Community Survey Public Use Microdata Sample records to adjust for under-reporting of children's PFD income in official statistics. We estimate that the PFD reduced the number of Alaskans with incomes below the US poverty threshold by 20%–40%. We measure only a small effect on income distribution: a 0.02 …

Efficacy Of Ropivacaine For Sub-Arachnoid Block In Patients With Recent History Of Scorpion Sting: A Case Series, Saurabh Trivedi, Hemendra Bhardwaj, Tapan K. Sahoo, Seema Gupta

Sultan Qaboos University Medical Journal

Failure of sub-arachnoid block (SAB), due to resistance to bupivacaine after a recent scorpion sting can lead to multiple block attempts and subsequent conversion to general anaesthesia. We report this case series of 10 patients with successful SAB with newly launched 0.75% hyperbaric ropivacaine, in patients with recent scorpion sting. Thus, intrathecal hyperbaric ropivacaine may be considered as the local anaesthetic agent of choice in patients with scorpion sting to prevent failure of SAB.

Keywords: Bupivacaine; Ropivacaine; Scorpion Stings; Spinal Anaesthesia.

Fetal alcohol spectrum disorders (FASDs) are leading causes of neurodevelopmental disability but cannot be diagnosed early in utero. Because several microRNAs (miRNAs) are implicated in other neurological and neurodevelopmental disorders, the effects of EtOH exposure on the expression of these miRNAs and their target genes and pathways were assessed. In women who drank alcohol (EtOH) during pregnancy and non-drinking controls, matched individually for fetal sex and gestational age, the levels of miRNAs in fetal brain-derived exosomes (FB-Es) isolated from the mothers’ serum correlated well with the contents of the corresponding fetal brain tissues obtained after voluntary pregnancy termination. In six …

Aba-Mediated Regulation Of Rice Grain Quality And Seed Dormancy Via The Nf-Yb1-Slrl2-Bhlh144 Module, Jin-Dong Wang, Jing Wang, Li-Chun Huang, Li-Jun Kan, Chu-Xin Wang, Min Xiong, Peng Zhou, Li-Hui Zhou, Chen Chen, Dong-Sheng Zhao, Xiao-Lei Fan, Chang-Quan Zhang, Yong Zhou, Lin Zhang, Qiao-Quan Liu, Qian-Feng Li

Abscisic acid (ABA) plays a crucial role in promoting plant stress resistance and seed dormancy. However, how ABA regulates rice quality remains unclear. This study identifies a key transcription factor SLR1-like2 (SLRL2), which mediates the ABA-regulated amylose content (AC) of rice. Mechanistically, SLRL2 interacts with NF-YB1 to co-regulate Wx, a determinant of AC and rice quality. In contrast to SLR1, SLRL2 is ABA inducible but insensitive to GA. In addition, SLRL2 exhibits DNA-binding activity and directly regulates the expression of Wx, bHLH144 and MFT2. SLRL2 competes with NF-YC12 for interaction with NF-YB1. NF-YB1 also directly represses SLRL2 transcription. Genetic validation …

Glioblastoma Disrupts Cortical Network Activity At Multiple Spatial And Temporal Scales, Jochen Meyer, Kwanha Yu, Estefania Luna-Figueroa, Benjamin Deneen, Jeffrey Noebels

Faculty, Staff and Students Publications

The emergence of glioblastoma in cortical tissue initiates early and persistent neural hyperexcitability with signs ranging from mild cognitive impairment to convulsive seizures. The influence of peritumoral synaptic density, expansion dynamics, and spatial contours of excess glutamate upon higher order neuronal network modularity is unknown. We combined cellular and widefield imaging of calcium and glutamate fluorescent reporters in two glioblastoma mouse models with distinct synaptic microenvironments and infiltration profiles. Functional metrics of neural ensembles are dysregulated during tumor invasion depending on the stage of malignant progression and tumor cell proximity. Neural activity is differentially modulated during periods of accelerated and …

Faculty, Staff and Students Publications

The epithelial cell lining of the oviduct plays an important role in oocyte pickup, sperm migration, preimplantation embryo development, and embryo transport. The oviduct epithelial cell layer comprises ciliated and nonciliated secretory cells. The ciliary function has been shown to support gamete and embryo movement in the oviduct, yet secretory cell function has not been well characterized. Therefore, our goal was to generate a secretory cell-specific Cre recombinase mouse model to study the role of the oviductal secretory cells. A knock-in mouse model, Ovgp1Cre:eGFP, was created by expressing Cre from the endogenous Ovgp1 (oviductal glycoprotein 1) locus, with enhanced green …

School of Nursing and Midwifery

Many coastal and rural areas in Britain are deprived. This regional aspect multiplies the effect of digital exclusion for older people. Younger people in these regions can also be digitally excluded. Codesigning digital technologies, using the natural and heritage resources of such regions would address this, but is rarely done. We present our methods and preliminary results, half-way through a 30-month project to develop novel technologies in extended reality, underwater telepresence, digital social games, and artificial intelligence voice interfaces and to use these assets to tackle digital exclusion. We are taking an intergenerational approach, working with 35 partner organizations, some …

Bagging Improves The Performance Of Deep Learning-Based Semantic Segmentation With Limited Labeled Images: A Case Study Of Crop Segmentation For High-Throughput Plant Phenotyping, Yinglun Zhan, Yuzhen Zhou, Geng Bai, Yufeng Ge

Department of Statistics: Faculty Publications

Advancements in imaging, computer vision, and automation have revolutionized various fields, including field-based high-throughput plant phenotyping (FHTPP). This integration allows for the rapid and accurate measurement of plant traits. Deep Convolutional Neural Networks (DCNNs) have emerged as a powerful tool in FHTPP, particularly in crop segmentation—identifying crops from the background—crucial for trait analysis. However, the effectiveness of DCNNs often hinges on the availability of large, labeled datasets, which poses a challenge due to the high cost of labeling. In this study, a deep learning with bagging approach is introduced to enhance crop segmentation using high-resolution RGB images, tested on the …
