Behavior Of Concrete Reinforced With Date Palm Fibers, Elias Ali

Faculty Scholarship

In recent decades, researchers have begun to investigate innovative sustainable construction materials for the development of greener and more environmentally friendly infrastructures. The main purpose of this article is to investigate the possibility of employing date palm tree waste as a natural fiber alternative for conventional steel and polypropylene fibers (PPFs) in concrete. Date palm fibers are a common agricultural waste in Middle Eastern nations, particularly Saudi Arabia. As a result, this research examined the engineering properties of high‐strength concrete using date palm fibers, as well as the performance of traditional steel and PPF concrete. The concrete samples were made …

The Mid‑Pleistocene Transition: A Delayed Response To An Increasing Positive Feedback?, Anne Willem Omta, Peter Thomas

Faculty Scholarship

Glacial–interglacial cycles constitute large natural variations in Earth’s climate. The Mid-Pleistocene Transition (MPT) marks a shift of the dominant periodicity of these climate cycles from ∼40 to ∼100 kyr. Recently, it has been suggested that this shift resulted from a gradual increase in the internal period (or equivalently, a decrease in the natural frequency) of the system. As a result, the system would then have locked to ever higher multiples of the external forcing period. We find that the internal period is sensitive to the strength of positive feedbacks in the climate system. Using a carbon cycle model in which …

Materials and Methods: A cross-sectional study of the 2013–2014 National Health and Nutrition Examination Survey (n = 4555). Outcome measure: PD using clinical attachment loss (measured as none, mild, moderate, or severe). The main independent variables were self-reported chronic conditions, while other covariates included demographic and behavioral variables. Classification and regression tree analysis was used to identify combinations of specific chronic conditions …

Gamification In Education: A Study Of Design-Based Learning In Operationalizing A Game Studio For Serious Games, James Hutson, Ben Fulcher, Joe Weber

Faculty Scholarship

The gamification of learning has proven educational benefits, especially in secondary education. Studies confirm the successful engagement of students with improved time on task, motivation and learning outcomes. At the same time, there remains little research on games and learning at the postsecondary level of education where traditional pedagogies remain the norm. Studies that have been conducted remain almost exclusively restricted to science programs, including medicine and engineering. Moreover, postsecondary subject-matter experts who have created their own gamified experiences often are forced to do so on an ad hoc basis either on their own, teaching themselves game engines, or with …

Discredited Data, Ngozi Okidegbe

Faculty Scholarship

Jurisdictions are increasingly employing pretrial algorithms as a solution to the racial and socioeconomic inequities in the bail system. But in practice, pretrial algorithms have reproduced the very inequities they were intended to correct. Scholars have diagnosed this problem as the biased data problem: pretrial algorithms generate racially and socioeconomically biased predictions, because they are constructed and trained with biased data.
/="/">
/="/">This Article contends that biased data is not the sole cause of algorithmic discrimination. Another reason pretrial algorithms produce biased results is that they are exclusively built and trained with data from carceral knowledge sources – the …

Characterizing Legal Implications For The Use Of Transboundary Aquifers, Gabriel Eckstein

Faculty Scholarship

Groundwater resources that traverse political boundaries are becoming increasingly important sources of freshwater in international and intranational arenas worldwide. This is a direct extension of the growing need for new sources of freshwater, as well as the impact that excessive extraction, pollution, climate change, and other anthropogenic activities have had on surface waters. It is also a function of the growing realization that groundwater respects no political boundaries, and that aquifers traverse jurisdictional lines at all levels of political geography.

Due to this growing awareness, questions pertaining to responsibility and liability are now being raised in relation to the use, …

Do Not Put All Your Eggs In One Basket: Social Perspectives On Desalination And Water Recycling In Israel, Gretchen Sneegas, Lucas Seghezzo, Christian Brannstrom, Wendy Jepson, Gabriel Eckstein

Faculty Scholarship

Israel has set ambitious goals in terms of the widespread adoption of desalination and water recycling technologies. Policymakers in Israel consider these technologies as the key to improve urban water security but knowledge of stakeholder views on this policy approach is not well established. We deployed the Q-methodology, a qualitative–quantitative approach, to empirically determine social perspectives on desalination and water recycling across a wide range of stakeholders in the Israeli water sector. We identified the following four distinctive social perspectives: (1) desalination should be the option of last resort; (2) desalination is moving us to an infinite resource; (3) equating …

Running On Empty: Ford V. Montana And The Folly Of Minimum Contacts, James P. George

Faculty Scholarship

Jurisdictional contests are in disarray. Criticisms date back to the issuance of International Shoe Co. v. Washington but the breakdown may be best illustrated in two recent Supreme Court opinions, the first rejecting California’s “sliding scale” that mixes general and specific contacts, the second using the discredited sliding scale to hold Ford amenable in states where accidents occurred.

California’s sliding scale is one variety of the contacts-relatedness tests, used in lower courts to have general contacts bolster weaker specific contacts. Some states—Montana and Minnesota for example—use the opposite extreme requiring a causal connection in defendant’s forum contacts, often using foreseeability …

Virtual Reality And Learning: A Case Study Of Experiential Pedagogy In Art History, James Hutson, Trent Olsen

Faculty Scholarship

While images are central to the discipline of art history, surprisingly little research has been conducted on the uses of digital environments for teaching in the discipline. Over the past decade, more studies have emerged considering the egalitarian space that can be used by students and teachers in web-based applications and social media. A body of literature has begun to emerge out of a small network of scholars and educators interested in digital humanities and art history, providing examples of how new tools can be integrated into the standard slideshow and lecture format of the field. At the same time, …

Balancing Rights And Responsibilities: The Role Of Government And Citizens In Combatting Gun Violence, Michael Ulrich

Faculty Scholarship

Congress passed the first federal legislation on firearms safety in decades at nearly the same moment that the Supreme Court issued its first major Second Amendment decision since 2008. It will take time to assess the effects of these actions on both gun safety and Second Amendment rights, but, with gun violence skyrocketing across the country, it is clear that finding a balance between rights and safety is desperately needed. The public is ill-equipped to protect itself against the broad harms of gun violence, so the government has a central role to play in addressing those harms and the racial …

Marshalling Copyright Knowledge To Understand Four Decades Of Berne, Peter K. Yu

Faculty Scholarship

In the year 1978, the 1976 Copyright Act had just entered into effect. Marshall Leaffer, whom this article will affectionately refer to by his first name, had just completed his duties as an attorney advisor at the U.S. Copyright Office. On his way to academia, he, like the fictional character Captain William “Buck” Rogers, was to experience cosmic forces beyond all comprehension. In a freak mishap, his car veered off a rarely used mountain road and was frozen by temperatures beyond imagination. He did not return to academia until more than forty years later. What will he discover upon his …

Lgd-4033 And Mk-677 Use Impacts Body Composition, Circulating Biomarkers, And Skeletal Muscle Androgenic Hormone And Receptor Content: A Case Report, Thomas D. Cardaci, Steven B. Machek, Dylan T. Wilburn, Jeffrey L. Heileson, Dillon R. Harris, Harry P. Cintineo, Darryn S. Willoughby

Faculty Scholarship

LGD-4033, a selective androgen receptor modulator, and MK-677, a growth hormone secretagogue, are becoming increasingly used amongst recreationally-active demographics. However, limited data exist describing their effects on health- and androgen-related biomarkers. The purpose of this case study is to report changes in body composition and biomarkers during and after continued co-administration of LGD-4033 and MK-677. We additionally aimed to examine muscular strength and intramuscular androgen-associated biomarkers relative to non-users. A 25-year-old male ingested LGD-4033 [10 mg] and MK-677 [15 mg] daily for 5 weeks. Blood and body composition metrics were obtained pre-, on-, and post-cycle. One repetition maximum (1RM) leg …

The Impact Of Obesity And Adipokines On Breast And Gynecologic Malignancies, Surabhi Tewari, Roberto Vargas, Ofer Reizes

Faculty Scholarship

The link between obesity and multiple disease comorbidities is well established. In 2003, Calle and colleagues presented the relationship between obesity and several cancer types, including breast, ovarian, and endometrial malignancies. Nearly, 20% of cancer-related deaths in females can be accounted for by obesity. Identifying obesity as a risk factor for cancer led to a focus on the role of fat-secreted cytokines, known as adipokines, on carcinogenesis and tumor progression. Early studies indicated that the adipokine leptin increases cell proliferation, invasion, and inhibition of apoptosis in multiple cancer types. As a greater appreciation of the obesity–cancer link has amassed, we …

Proportioning Collection Space And Learning In An Academic Library: Collection Performance Indicators, Christopher Stewart, Louise Lowe

Faculty Scholarship

Assessment on university campuses increasingly emphasizes learning outcomes and student success. Academic librarians need to identify relationships between their collection spaces and the learning activities of the university in order to play a role in the environment of assessment. Measuring the propor- tions of discipline-oriented content of library collections and comparing those proportions to discipline-oriented learning activities produces collection performance indicators. Academic libraries can use collection performance indicators to assess how well their collection spaces correspond to student demand and student success using readily available metrics. Collection performance indicators answers a gap in library literature per- taining to relationships between …

Cognitive Functioning And Prevalence Of Seizures Among Older Persons In Uganda: A Hospital-Based, Cross-Sectional Study, Martha Sajatovic

Faculty Scholarship

There is limited data on the prevalence of seizures and dementia among older persons in Uganda. We evaluated cognitive functioning, and the prevalence and factors associated with seizures among older persons attending an outpatient medical clinic in Uganda. We randomly selected older adults (60 years and above) attending Kiruddu National Referral Hospital medical outpatient clinics between October 2020 and March 2021. We excluded individuals with a history of head injury, brain tumors, mental retardation, co-morbidity with HIV and patients who have had recent brain surgery. Cognitive functioning was assessed using the Identification for Dementia in Elderly Africans (IDEA) tool. We …

Public Carry Versus Public Health — The Harms To Come From The Supreme Court’S Decision In Bruen, Michael Ulrich

Faculty Scholarship

In June, the U.S. Supreme Court ruled in New York State Rifle & Pistol Association v. Bruen that the Second Amendment provides a constitutionally protected right to carry firearms in public. The decision is already creating turmoil in the form of political and public backlash and a scramble by policymakers to find new ways to combat the growing gun-violence epidemic in the United States. The majority opinion in Bruen, written by Justice Clarence Thomas, will have a devastating impact on efforts to mitigate gun violence and address racial disparities, but the reasoning used in the decision could cause even …

Faculty Scholarship

The white paper chronicles the 25-year history of one graduate school of social work’s efforts in competency-based curriculum innovation. The authors argue that curriculum change is organizational change and share their experiences with a variety of curriculum assessment, design, and delivery efforts. Beginning with the development of the first social work competencies (labeled Abilities), pioneering efforts in assessment and holistic curricular design and delivery are reviewed. A new, one-semester, social work generalist curriculum is introduced. Emphasis is placed on the importance of developing a competency-based curriculum that is integrated both horizontally and vertically and that engages the social work student …

Colorblind Capture, Jonathan Feingold

Faculty Scholarship

We are facing two converging waves of racial retrenchment. The first, which arose following the Civil Rights Movement, is nearing a legal milestone. This term or the next, the Supreme Court will prohibit affirmative action in higher education. When it does, the Court will cement decades of conservative jurisprudence that has systematically eroded the right to remedy racial inequality.

The second wave is more recent but no less significant. Following 2020’s global uprising for racial justice, rightwing forces launched a coordinated assault on antiracism itself. The campaign has enjoyed early success. As one measure, GOP officials have passed, proposed or …

A Virtual Reality Educational Game For The Ethics Of Cultural Heritage Repatriation, James Hutson, Ben Fulcher

Faculty Scholarship

The technology of virtual reality and the gamification of education has had proven educational benefits and has the ability to immerse students in a participatory learning experience. To capitalize on the strengths of the new digital medium, including immersion, engagement, and presence, a new educational game aims to teach the ethics of cultural heritage repatriation through the lens of art history. The use of games to address current issues and conceptualize a framework for understanding the complexities of geopolitics is not new but aligning these considerations with the pressing need to protect cultural heritage as seen in modern-day Ukraine is. …

The Environmental, Social, Governance (Esg) Debate Emerges From The Soil Of Climate Denial, Lawrence J. Trautman, Neal Newman

Faculty Scholarship

It has been almost six decades since Rachel Carson’s ominous warning of pending environmental disaster. During 2019 the United Nations requested urgent action from world leaders, given that “just over a decade is all that remains to stop irreversible damage from climate change.” With every passing year, damage resulting from destructive climate change causes increased pain, suffering, death and massive property loss. During 2020 and 2021 alone, severe weather events have included: destructive fires in California; record breaking freeze, power outage, and threat to the electrical grid in Texas; continuation of disruptive drought in U.S. Western states; and record-breaking high …

January 6, Ambiguously Inciting Speech, And The Overt-Acts Rule, Alan Z. Rozenshtein, Jed Handelsman Shugerman

Faculty Scholarship

A prosecution of Donald Trump for his role in the January 6 attack on the Capitol would have to address whether the First Amendment protects the inflammatory remarks he made at the “Stop the Steal” rally. A prosecution based solely on the content of Trump’s speech—whether for incitement, insurrection, or obstruction—would face serious constitutional difficulties under Brandenburg v. Ohio’s dual requirements of intent and likely imminence. But a prosecution need not rely solely on the content of Trump’s speech. It can also look to Trump’s actions: his order to the remove the magnetometers from the entrances to the rally and …

A Proposed Sec Cyber Data Disclosure Advisory Commission, Lawrence J. Trautman, Neal Newman

Faculty Scholarship

Constant cyber threats result in: intellectual property loss; data disruption; ransomware attacks; theft of valuable company intellectual property and sensitive customer information. During March 2022, The Securities and Exchange Commission (SEC) issued a proposed rule addressing Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure, which requires: 1. Current reporting about material cybersecurity incidents; 2. Periodic disclosures about a registrant’s policies and procedures to identify and manage cybersecurity risks; 3. Management’s role in implementing cybersecurity policies and procedures; 4. Board of directors’ cybersecurity expertise, if any, and its oversight of cybersecurity risk; 5. Registrants to provide updates about previously reported cybersecurity …

Content Moderation As Surveillance, Hannah Bloch-Wehba

Faculty Scholarship

Technology platforms are the new governments, and content moderation is the new law, or so goes a common refrain. As platforms increasingly turn toward new, automated mechanisms of enforcing their rules, the apparent power of the private sector seems only to grow. Yet beneath the surface lies a web of complex relationships between public and private authorities that call into question whether platforms truly possess such unilateral power. Law enforcement and police are exerting influence over platform content rules, giving governments a louder voice in supposedly “private” decisions. At the same time, law enforcement avails itself of the affordances of …

The Uniform Commercial Code Survey: Introduction, Jennifer S. Martin, Colin P. Marks, Wayne Barnes

Faculty Scholarship

Incorporating Baryon-Driven Contraction Of Dark Matter Halos In Rotation Curve Fits, Pengfei Li, Stacy S. Mcgaugh

Faculty Scholarship

The condensation of baryons within a dark matter (DM) halo during galaxy formation should result in some contraction of the halo as the combined system settles into equilibrium. We quantify this effect on the cuspy primordial halos predicted by DM-only simulations for the baryon distributions observed in the galaxies of the SPARC database. We find that the DM halos of high surface brightness galaxies (with Σeff 3; 100L pc-2 at 3.6 μm) experience strong contraction. Halos become more cuspy as a result of compression: the inner DM density slope increases with the baryonic surface mass density. We iteratively fit rotation …

The Planetary Sublime Part Ii Of The Problem Of An Unloving World, Jeremy Bendik-Keymer

Faculty Scholarship

This essay interprets Dipesh Chakrabarty’s The Climate of History in a Planetary Age in light of the European tradition of thought about the sublime. The first half of the essay stages Chakrabarty’s historiography within that tradition focusing on a critical understanding of Kant. Then, the essay considers how the trace of the sublime in Chakrabarty’s approach to planetary history is interpretable as a form of social alienation. That argument draws on the critical theory of Steven Vogel and decolonial critique. Finally, the essay considers the moods of protest as non-alienated responses to the planetary bypassing the coloniality of the sublime.

Pre Covid-19 Pandemic Use Of Telemedicine For Adherence Promotion In Patients With Psychotic Disorders: A Literature Review, Alyssa M. Edwards, Jordan C. Petitt, Sanjana Kumar, Jennifer B. Levin, Martha Sajatovic

A Blind Benchmark Of Analysis Tools To Infer Kinetic Rate Constants From Single-Molecule Fret Trajectories, Dorothy A. Erie, Lydia Kisley, Dushani Dunukara

Faculty Scholarship

Single-molecule FRET (smFRET) is a versatile technique to study the dynamics and function of biomolecules since it makes nanoscale movements detectable as fluorescence signals. The powerful ability to infer quantitative kinetic information from smFRET data is, however, complicated by experimental limitations. Diverse analysis tools have been developed to overcome these hurdles but a systematic comparison is lacking. Here, we report the results of a blind benchmark study assessing eleven analysis tools used to infer kinetic rate constants from smFRET trajectories. We test them against simulated and experimental data containing the most prominent difficulties encountered in analyzing smFRET experiments: different noise …

Inconceivable Families, Malinda L. Seymore

Faculty Scholarship

Basic biology tells us that each child has no more than two biological parents, one who supplies the egg and one who supplies the sperm. Adoption law in this country has generally followed biology, insisting only two parents be legally recognized for each child. Thus, every adoption begins with loss. Before a child can be adopted, that child must first be cut off from their family of birth, rendering the equation of adoption one of subtraction, not addition. This Article examines the biological model of adoption that insists on mimicking the nuclear family—erasing one set of parents and replacing them …

Bridge Building In Higher Education: Multi-Modal Mentoring Programs To Support Retention & Career Preparedness, James Hutson, Roger Nasser, Michael Marzano, Ryan Curtis, Elizabeth Macdonald, Sue Edele, Barbara Hosti-Marti

Faculty Scholarship

Despite the limitations on time for career preparedness and shrinking professional development budgets, mentoring remains as important as ever due to the interconnectedness in a global society and the changing demographics of postsecondary education students. The traditional-age population in college that lives on campus and does not work has been declining for over three decades. The majorities of current students that are now non-traditional, and work at least part-time are first-generation, and are pursuing degrees via distance or online learning. The importance of providing a diverse mentoring strategy for this new population is borne out in research in order to …
