Regularity And Mechanisms Of Water-Sand Inrushes Within Mining-Activated Faults, Zhang Shichuan, Huang Pu, Li Yangyang, Wang Chenggong, Wu Zhenhua

Coal Geology & Exploration

Background During underground coal mining, water-sand mixtures within faults may rush into mine floors. The water-sand inrushes are especially prominent under the conditions of high water-yield properties and loose filling structures in fault zones, severely threatening the safe mining of coal mines. Previous studies focus primarily on the impact of a single factor on inrushes. Hence, it is significant to systematical investigate the regularity of water-sand inrushes within faults under the combined effects of multiple factors. Methods Based on the fluid and granular mechanic theories, this study derived the instability criterion and flow formulas of water-sand mixtures. Using orthogonal experiments …

Attitudes Toward Seeking Mental Health Services Among Young African American Same-Sex-Oriented Men, Anthony Earl Fox

Walden Dissertations and Doctoral Studies

In 2018 suicide was the second leading cause of death for young people between the ages of 15 and 24 (CDC, 2018). Suicide and other factors like HIV, depression, and oppression may serve as barriers to seeking counseling among African American same-sex-oriented men ages 18-26. Due to a previous gap in the literature regarding barriers to seeking counseling, this study may support counselors in finding ways to address the disparity in counseling utilization among this population. Grounded in queer and social identity theories, the purpose of this quantitative study was to examine if adverse childhood experiences, current civic unrest, HIV, …

Unpacking Digital Transformation – Constructing A Framework Based On Industry Use Cases, Khawaja Asjad Saeed, Andrew William Green, Alison Brooke Hedrick

Faculty Articles

Based on industry use cases, we identify six distinct types of digital transformation (DT), each grounded in a specific concept or enabling technology. These DT types can be implemented individually or combined to drive transformation initiatives. While deploying a single DT type often focuses on improving operational efficiency or streamlining existing workflows, initiatives that combine multiple DT types tend to pursue more ambitious goals, such as the creation of new products, services, or business models. However, the complexity increases significantly with the integration of multiple DT types, as organizations must not only address behavioral changes but also overcome technical challenges …

Engagement, Motivation, And Interest In K-12 Science Education, Neil T M Bailie

Masters Projects

Interest, motivation, and engagement amongst science students is declining. This decline is primarily due to a loss of interest, motivation, self-efficacy, and perceived utility value (Bathgate & Schunn, 2017; Britner, 2008; Kraft, 2017).

Breast cancer is the most common malignancy in females and remains the leading cause of cancer-related deaths for women worldwide. The cellular and molecular basis of breast tumorigenesis is not completely understood partly due to the lack of human research models which simulate the development of breast cancer. Here, we developed a method for generating functional mammary-like cells (MCs) from human-induced pluripotent stem cells (iPSCs). The iPSC-MCs closely resemble human primary MCs at cellular, transcriptional, and functional levels. Using this method, a breast cancer model was generated using patient-derived iPSCs harboring germline

Inhibition Of The Caveolin-1 Pathway Promotes Apoptosis And Overcomes Pan-Tyrosine Kinase Inhibitor Resistance In Hepatocellular Carcinoma, Tasnuva D. Kabir, Samuel Beck, Lisa M. Stuart, Ji Li, Rui Hou, Peiwen Liu, Shelby Margolius, Claire Kim, Yu Suk Choi, Edward R. Bastow, Dianne J. Beveridge, Lisa Spalding, Ziyi Li, Florent Ginhoux, Pierce Chow, Michael Phillips, Andrew D. Redfern, George C. Yeoh, Alistair Forrest, Andrew J. Woo, Ankur Sharma, Jacob George, Geoffrey Mccaughan, Peter Leedman

Research outputs 2022 to 2026

Resistance to multi-tyrosine kinase inhibitors (TKI) is a major clinical concern in advanced hepatocellular carcinoma (HCC). Herein, we aimed to uncover the mechanisms underlying pan-TKI resistance and to identify potential therapeutic targets. We used multiple TKI-resistant HCC cell lines to identify caveolin-1 (CAV1) as a key driver of therapeutic resistance. CAV1 downregulation induced apoptosis, inhibited metastasis and restored TKI sensitivity in both inherent and acquired TKI-resistant HCC cells. Mechanistically, in acquired TKI-resistant cells aberrant CAV1/STAT3/P70S6K signalling is required for their survival, motility, and invasiveness. CAV1 inhibition reduced expression of dormancy regulators E-cadherin, RAC1 and p21, enhanced cancer stemness markers, and …

Qualitative Thematic Analysis Of Crisis Communications From The Digital Pulpits Of Megachurches During Covid-19, Ralph Dustin Henderson

Doctoral Dissertations and Projects

The purpose of this qualitative thematic analysis multi-case study was to explore how secular crisis communication theories were adopted and modified by theological themes in U.S. megachurches during the first six weeks of the COVID-19 pandemic related lockdowns. Image Repair Theory (IRT), Discourse Renewal Theory (DRT), and Rhetorical Arena Theory (RAT) were examined alongside Christian themes (Theodicy, Radical Love, Physical Care, and Nontraditional Stakeholder Scope). Thematic analysis of sermon transcripts from 18 megachurches showed that IRT modified: high-attribution tactics were minimal; denial (via IMRA theodicy) defended the Church Universal (CU); evasion justified Church Local (CL)actions; and offensiveness reduction (esp. Transcendence) …

Assessment Of Dnase Activity By Ratiometric Fluorescence Resonance Energy Transfer, Candace L Minchew, Vladimir V Didenko

Faculty, Staff and Students Publications

The present protocol describes a simple and sensitive ratiometric Förster resonance energy transfer (FRET) assay for the detection and quantitative assessment of DNase activity. Ratiometric FRET measurements make use of the ratio of donor and acceptor emission signals. The assay detects single-stranded DNA breaks using a staple-shaped, dual-tagged 38-mer FRET oligoprobe, employed as a real-time DNA cleavage sensor. The main application of the described approach is the quantitative assessment of the effects of reaction conditions, such as pH, temperature, and buffer composition, on DNase activity. Due to its ability to detect even minor and slow DNA cleavage, the assay is …

By illustrating CMD’s adaptability and value, this …

Constructivist Media Decoding In Elementary School: Media Literacy Instruction Across A School Year, Faith Rogow, Bridget Crossman, Michele Coolbeth, Janet Balk

Journal of Media Literacy Education

In 2021, Ithaca College’s Project Look Sharp conducted a pilot project to demonstrate that school librarians were in a unique position to provide media literacy instruction and function as building and district leaders to mentor teachers in media literacy integration. The initiative taught librarians to use constructivist media decoding (CMD) – an inquiry-based, curriculum driven approach to media analysis and production. This article, informed by the evaluation of that effort, offers a qualitative view from three elementary school librarians who were part of the pilot cohort. They describe how they implemented CMD in ways that can be duplicated by other …

A Systematic Review Of Transmedia Literacy: Implications For Lifelong Learning, Rafel Meyerhofer-Parra

Journal of Media Literacy Education

One of the main objectives of international agendas is the promotion of lifelong learning opportunities. Transmedia literacy, usually acquired informally, offers many of the key skills, competences and strategies to ensure learning in a world where technology has a predominant role. However, no analyses reporting the impact of their use are systematically identified in the literature. Therefore, a systematic review of the literature on transmedia literacy and its practices is proposed, searching 4 databases and analysing a total of 42 articles.

Insights From Educators: Integrating Ai Literacy Into Media Literacy Education In Practice, Stephanie Jean Tsang

Journal of Media Literacy Education

Through in-depth interviews with junior high school teachers in Hong Kong who participated in a media and artificial intelligence literacy program intervention, this research highlights the importance of prioritizing values and ethics education over technical proficiency when incorporating artificial intelligence (AI) into media literacy training. While quantitatively assessing students’ literacy levels posed challenges, future media literacy programs should concentrate on introducing technological terminology and concepts, promoting awareness of potential issues, instilling values for responsible technology use, and fostering empathy to create a harmonious online environment. By focusing on fundamental values and key concepts rather than following fleeting AI trends, educators …

Classroom Contexts: Teachers Talk Teaching Media Literacy, Sakshi Bhalla, Michelle R. Nelson, Michael Spikes

Journal of Media Literacy Education

In this study, we examine the lived experiences of educators who engage with youth through media literacy education. While prior research has examined the efficacy of media literacy education interventions, little attention has been paid to the contexts in which these are conducted. Our analysis of 20 semistructured interviews reveals how the structural context illuminates several “divides,” shaping how media literacy is taught and experienced. Three major themes emerged from the data: (1) teachers and high school students inhabit distinct media worlds, shaping their media understanding differently; (2) the socio-economic status of the school determines whether media literacy is taught …

Unmasking A New Dialect Of Deception: Leveraging The Federal Trade Commission To Combat Deceptive And Exploitative Corporate Policies, Hani Baltagi

Cleveland State Law Review

Corporate social responsibility initiatives have transformed fair labor policies into powerful marketing tools, but the gap between the public promise to embrace ethical labor practices and actual corporate compliance with such practices has widened. This has the effect of not only impeding the average consumer’s purchasing decision, but perpetuating—if not catalyzing—labor exploitation across the world. The existence of this paradigm thus necessitates additional, heightened intervention by none other than Federal Trade Commission (FTC).

The FTC’s three-pronged test for deception—previously created to combat other forms of deceptive practices—provides an accountability framework for deceptive marketing claims that utilize unfollowed, self-adopted corporate fair …

For The Greater Good: Civil Commitment For Addiction Amid The Overdose Epidemic, Steven P. Meerschaert

Cleveland State Law Review

America is facing a reckoning born of its own duality. Our society is gradually embracing an increasingly permissive stance on recreational drug use, while at the same time we lament the human costs of addiction. What the media has dubbed the “opioid epidemic” has seen increases in drug addiction diagnoses and opioid-involved overdose deaths nearly every year since 1999. In a rush to designate guilty parties and to crown a “gold standard” for treatment options, we have focused on theoretically flawed approaches that fail to follow the science precisely. At the same time, we dismiss validated treatment modalities in their …
