Investigating Privacy Policies Using Policylint Tool, Tricia Camaya

Cybersecurity Undergraduate Research Showcase

Organizations essentially inform clients about data collection and sharing practices through privacy policies. Recent research has proposed tools to help users better comprehend these lengthy and intricate legal documents that summarize collection and sharing. However, these instruments have a significant flaw. They overlook the possibility of contradictions within a particular policy. This paper introduces PolicyLint, a tool for analyzing privacy policies that simultaneously considers negation and varying semantic levels of data objects and entities. PolicyLint accomplishes this by using sentence-level natural language processing to automatically create ontologies from a large corpus of privacy policies and capturing both positive and negative …

G-Rich Motifs Within Phosphorothioate-Based Antisense Oligonucleotides (Asos) Drive Activation Of Fxn Expression Through Indirect Effects, Feng Wang, Ezequiel Calvo-Roitberg, Julia M Rembetsy-Brown, Minggang Fang, Jacquelyn Sousa, Zachary J Kartje, Pranathi Meda Krishnamurthy, Jonathan Lee, Michael R Green, Athma A Pai, Jonathan K Watts

Faculty, Staff and Student Publications

Friedreich's ataxia is an incurable disease caused by frataxin (FXN) protein deficiency, which is mostly induced by GAA repeat expansion in intron 1 of the FXN gene. Here, we identified antisense oligonucleotides (ASOs), complementary to two regions within the first intron of FXN pre-mRNA, which could increase FXN mRNA by ∼2-fold in patient fibroblasts. The increase in FXN mRNA was confirmed by the identification of multiple overlapping FXN-activating ASOs at each region, two independent RNA quantification assays, and normalization by multiple housekeeping genes. Experiments on cells with the ASO-binding sites deleted indicate that the ASO-induced FXN activation was driven by …

Examining The Relationship Between Stomiiform Fish Morphology And Their Ecological Traits, Mikayla L. Twiss

All HCAS Student Capstones, Theses, and Dissertations

Trait-based ecology characterizes individuals’ functional attributes to better understand and predict their interactions with other species and their environments. Utilizing morphological traits to describe functional groups has helped group species with similar ecological niches that are not necessarily taxonomically related. Within the deep-pelagic fishes, the Order Stomiiformes exhibits high morphological and species diversity, and many species undertake diel vertical migration (DVM). While the morphology and behavior of stomiiform fishes have been extensively studied and described through taxonomic assessments, the connection between their form and function regarding their DVM types, morphotypes, and daytime depth distributions is not well known. Here, three …

Exploring The Acute Cardiovascular Effects Of Floatation-Rest., M C Flux, Thomas H. Fine, Tate Poplin, Obada Al Zoubi, William A. Schoenhals, Jesse Schettler, Hazem H. Refai, Jessyca Naegele, Colleen Wohlrab, Hung-Wen Yeh, Christopher A. Lowry, Jason C. Levine, Ryan Smith, Sahib S. Khalsa, Justin S. Feinstein

Manuscripts, Articles, Book Chapters and Other Papers

The central nervous system (CNS) exerts a strong regulatory influence over the cardiovascular system in response to environmental demands. Floatation-REST (Reduced Environmental Stimulation Therapy) is an intervention that minimizes stimulation from the environment, yet little is known about the autonomic consequences of reducing external sensory input to the CNS. We recently found that Floatation-REST induces a strong anxiolytic effect in anxious patients while paradoxically enhancing their interoceptive awareness for cardiorespiratory sensations. To further investigate the physiologic nature of this anxiolytic effect, the present study measured acute cardiovascular changes during Floatation-REST using wireless and waterproof equipment that allowed for concurrent measurement …

Linguistic And Ontological Concept Formation: The Lion Method, Göran Goldkuhl

The Qualitative Report

Concept formation is a demanding task in social research. A methodological approach (called LION) is presented that emphasizes the clarification of concepts based on linguistic and ontological views. This method originates from a qualitative-pragmatist tradition of studies of work-practices in organizational settings and it is explicitly based on the linguistic turn and the practice turn in social research. It is also based on the articulation of seven conceptualization maxims. Its aim is to bring rigor to the conceptualizing process and clarity to resulting conceptualizations. The method is illustrated through an analysis example from service management. The concepts of “value-in-use” and …

Zur And Zinc Increase Expression Of E. Coli Ribosomal Protein L31 Through Rna-Mediated Repression Of The Repressor L31p, Rebecca A Rasmussen, Suning Wang, Jeannie M Camarillo, Victoria Sosnowski, Byoung-Kyu Cho, Young Ah Goo, Julius B Lucks, Thomas V O'Halloran

2020-Current year OA Pubs

Bacteria can adapt in response to numerous stress conditions. One such stress condition is zinc depletion. The zinc-sensing transcription factor Zur regulates the way numerous bacterial species respond to severe changes in zinc availability. Under zinc sufficient conditions, Zn-loaded Zur (Zn2-Zur) is well-known to repress transcription of genes encoding zinc uptake transporters and paralogues of a few ribosomal proteins. Here, we report the discovery and mechanistic basis for the ability of Zur to up-regulate expression of the ribosomal protein L31 in response to zinc in E. coli. Through genetic mutations and reporter gene assays, we find that Zur achieves the …

Effect Of Education On Self-Reported Health, Mai Le '24

Student Research

Human Capital Theory pointed out health as a possible return to education. The question at the center of this research is if education can improve health. Replicating the work of Goesling (2007) on new data from the 2000-2022 Current Population Survey (CPS), a cross-sectional probit analysis shows a positive relationship between educational level and self-reported health. This relationship is robust and significant across age groups.

Numerical And Approximate Analytic Solutions Of Second- Order Nonlinear Boundary Value Problems, Chein-Shan Liu, Jian-Hung Shen, Yung-Wei Chen

Journal of Marine Science and Technology–Taiwan

The shooting method consists of guessing unknown initial values, transforming a second-order nonlinear boundary value problem (BVP) to an initial value problem and integrating it to obtain the values at the right end to match the specified boundary condition, which acts as a target equation. In the shooting method, the key issue is accurately solving the target equation to obtain highly precise initial values. Due to the implicit and nonlinear property, we develop a generalized derivative-free Newton method (GDFNM) to solve the target equation, which offers very accurate initial values. Numerical examples are examined to show that the shooting method …

Optimization Of Circular Silencers Internally Hybridized With Multiple Reverse Chambers Using The Ga Method, Min-Chie Chiu, Ying-Chun Chang, Tian-Syung Lan, Ho-Sheng Chen

Journal of Marine Science and Technology–Taiwan

A noise abatement method using an eigen function in conjunction with an optimizer (Genetic Algorithm) under a space-constrain situation is proposed in this study concerning a high order wave propagation effect. An eigen function is used to describe an acoustical field and shorten the acoustical model in a four-pole transfer matrix form. The system’s four-pole matrix estimates the Transmission Loss (TL) for the silencers by multiplying individual four-pole matrices.

Additionally, a case study of an air compressor’s broadband noise elimination is introduced. Three types of circular reverse silencers (silencers A-C) internally hybridized with multiple straight chambers are adopted to efficiently …

Numerical Investigation Of The Uncertainty Of Typhoon Wave Parameters Retrieval Using Hf Radar, Toan Duy Dao, Hwa Chien

Journal of Marine Science and Technology–Taiwan

The aim of this study was to identify the sources of uncertainties of typhoon wave field monitoring using HF radar and to quantitatively assess the bias of the wave parameters, such as significant wave height and mean period, retrieved under various conditions. The strategy was to apply a purely numerical simulation of the Doppler-range spectra and then compare the estimation results to the target. For the quantitative investigation, a numerical test-bed was established. The test-bed was used to simulate the Doppler spectra based on Barrick’s (1972) theory by using the input of the directional wave spectra. The typhoon wave spectra …

Of Crowns, Pilgrims, And Non-Asinine Mules, Moshe Gold

Jesuit Higher Education: A Journal

John O’Malley, S.J.’s emphasis on rhetoric challenges students to reconsider not only the significance of the history of rhetoric in relation to St. Ignatius’ texts, but also the importance of rhetoric in their own discourses. In this essay, I focus on one specific event in Ignatius’ Acts, an event replete with rhetorical, textual, biblical (both the New Testament and Tanakh, the Hebrew scriptures), and historical considerations, but which, surprisingly, does not appear as a major focus in John O’Malley, S.J.’s voluminous books: Ignatius on a mule, encountering “the Moor” (un moro). I outline a method of guiding students through …

Barriers To Implementing A Work-Based Learning Program: A Health Science Educator Perspective, Daniel Harrison

Dissertations

Career and Technical Education programs’ mission statement is to supply a skilled workforce for all industries (ACTE, 2021). The Health Science pathway lags behind other industry sectors in active work-based learning programs (Greenfield & Stevens, 2018). Therefore, this study examines the potential barriers to implementing work-based learning programs within the Health Science pathway. The qualitative descriptive investigation into the three types of work-based learning of visits to the workplace, work-like experiences, and employment discovered critical findings regarding healthcare requirements, scheduling conflicts, and access to facilities. Finding 1 details healthcare requirements as the most significant barrier to work-based learning programs. The …

Educators’ And Parents’ Attitudes Toward The Inclusion Of Students With Emotional And Behavior Disorders, Shannon L. Howze

Dissertations

Educating students with emotional and behavior disorders (EBD) has historically been a difficult task for educators (McKenna et al., 2021). The general education setting comes with many barriers when attempting to include students with EBD to the equation. Parents are instrumental to the success of their students with EBD regardless to the setting. Educators may lack in the skills needed to communicate, educate, and understand students with EBD. Without educators and parents collectively communicating and collaborating, students with EBD will not have the opportunity to have the positive experiences and outcomes to be successful. Applying the theoretical frameworks of Bandura’s …

Using The Social-Ecological Model To Better Understand Sexual Assertiveness Among Undergraduate Women At An Institution Of Higher Education In The Southeastern United States, Lisa Wright

Dissertations

This study examined sexual assertiveness among female undergraduate students at an institution of higher education in the southeastern United States from the context of the social-ecological model. An online survey instrument examined sexual assertiveness, sexual communication self-efficacy, campus climate, and sexual scripts. Structural equation modeling was used to examine the relationships between these variables and all variables significantly predicted sexual assertiveness individually, but when examining the relationships collectively, only sexual communication self-efficacy and campus climate remained significant predictors of sexual assertiveness.

The Impact Of A Five-Day Number Sense Intervention On High School Student's Quantitative Reasoning Skills And Self-Efficacy, Rebecca Steele-Mackey

Dissertations

Understanding numerical quantities and applying this knowledge in practical applications is essential throughout life. A well-developed number sense comes from learning foundational skills and continuing to rely on these skills and concepts in higher mathematical education as well as in adulthood. Prior research shows that K-8 students lack a conceptual understanding of fraction, decimal, and percentage concepts (NCTM, 2009). While there is literature that identifies a deficit in these mathematical areas, there is a need to examine possible activities and interventions that can be performed throughout secondary education courses that support growth in students' conceptual understanding of rational number concepts. …

The Presence Of Relational Trust In Teacher-Principal Relationships And The Correlation Of Teacher Intent-To-Persist And Teacher Efficacy, Maryum Bilal

Dissertations

Principals and teachers must work together for students to be academically successful. Teachers directly influence the students, and principals directly affect the teachers. Before students' success can occur, the principal and teachers must have a relationship. The development of trust begins with leaders who have quality relationships with their teachers (Bryk & Schneider, 2002). When teachers trust their principals, teachers are loyal and develop self-efficacy. According to Lacks and Watson (2018), teacher self-efficacy is developed through significant interactions with the principal, making teachers feel better about themselves and their collective mission, and they become more effective in the classroom. Trust …

Dissertations

Alpha-gal syndrome (AGS or sometimes called red meat allergy) is a result of the development of specific IgE antibodies to the oligosaccharide galactose-α-1,3-galactose (α-gal) after a person has had exposure to tick bites. This dissertation investigates four common tick species found in North America: the lone-star tick (Amblyomma americanum), the Gulf-Coast tick (Amblyomma maculatum), the American dog tick (Dermacentor variabilis), and the black-legged tick (Ixodes scapularis) for the presence of α-gal by utilizing a combination of immunoproteomic approaches and carbohydrate analysis techniques.

Anti-α-gal IgM antibodies (M86) were used in immunoblotting to detect …

Strategic Human Resource Management Practice Integration And Organizational Ambidexterity In Vuca Times, Gizzatta Cook

Dissertations

ABSTRACT

The failure rate of business strategy implementation hovers around 50% due to a lack of organizational ambidexterity in the realities associated with a four-dimensional paradigm referred to as a volatile, uncertain, complex, and ambiguous (VUCA) environment (Chattopadhyay et al., 2017). Anwar and Abdullah (2021) state that organizational success depends highly on how well organizational leaders manage and administer their human resource management practices. Today's successful organizations must adapt to societal changes to survive and thrive (Chattopadhyay et al., 2017).

Surviving and thriving beyond today’s organizational constraints also involves a business's ability to demonstrate organizational ambidexterity. Organizational ambidexterity is the …

Lateral Decubitus And Prone Positioning: An Objective Structured Clinical Evaluation, David Hesley-Hernandez, James Bailey

Doctoral Projects

Improper positioning of patients in the lateral decubitus or prone positions can lead to significant complications, including but not limited to: airway and invasive line loss, physiologic derangements, soft tissue injury, and peripheral nerve injuries (PNI) (Barash et al., 2017; Butterworth et al., 2018). Chui et al.’s (2018) analysis found that PNIs accounted for 12% of anesthesia malpractice since 1990, making PNIs costly. PNIs effects are not limited to cost and result in increased lengths of stay, increased pain levels, and decreased quality of life (Wojtkiewicz et al., 2015). The massive effect poor positioning can have requires that the anesthesia …

Objective Structured Clinical Examination For Intraoperative Hypotension And Hypertension Management, Andrew Mcginity, James David Ingram

Doctoral Projects

Managing intraoperative hypotension and hypertension is a non-technical skill anesthesia providers need to maintain patient safety. Upon transitioning from didactic training to clinical training, SRNAs may find it difficult to manage a patient’s blood pressure intraoperatively. The ultimate consequence of the delayed or improper treatment of intraoperative blood pressure perturbations is end-organ damage at the patient’s expense. Unintentionally causing a patient harm will lead to an SRNA losing confidence in their abilities. This OSCE is intended to increase SRNA confidence and competence regarding intraoperative hypotension and hypertension management before entering the clinical arena.

The hypotension and hypertension management tools and …

Does The Use Of Mental Health Screenings And Targeted Stress Interventions Improve Mental Health Outcomes In Outpatient Clinic Staff?, Mary Benson

Doctoral Projects

The Perceived Stress Scale (PSS) has been used as a classic stress assessment instrument to evaluate perceived stress across many settings. As stress is the primary phenomenon in this review due to varying stressors, including infectious diseases among healthcare workers, the PSS is the most appropriate scale for evaluating the degree to which a health worker feels stressed. In addition, the PSS is valuable as it encompasses ten items that researchers use to explore how respondents react to stress due to unpredictable events. Thus, this DNP project is based on the postulation that screening with the PSS and applying stress …
