Sm-Fplf: Link-State Prediction For Software-Defined Dcn Power Optimization, Mohammed Nsaif, Gergely Kovasznai, Ali Malik, Ruairí De Fréin

Articles

Efficient monitoring systems that optimize resource allocation, reduce energy usage through machine learning and flow aggregation routing techniques, are needed due to the escalating power consumption of data center networks, which, as has been recently reported, account for up to eight percent of global energy consumption, posing environmental operational concerns. We propose a software-defined data-center monitoring algorithm that reduces power consumption by: 1) using a GPU implementation of a Stacked Long Short-Term Memory Recurrent Neural Network (RNN) model for link utilization prediction, thus reducing monitoring overhead; and 2) utilizing a flow aggregation routing algorithm with feedback from online, OpenFlow-powered monitoring …

Functional Investigation Of Shaggy, An Inhibitor Of Canonical Wnt Signaling, In The Tardigrade Hypsibius Exemplaris, Raul A. Chavarria

UNF Graduate Theses and Dissertations

Tardigrades have a highly simplified anteroposterior (AP) axis. The mechanisms that regulate the development of this secondarily simplified AP axis are not known. In many animals, the canonical Wnt (cWnt) signaling pathway regulates primary axis establishment through antagonistic interactions with inhibitors of cWnt signaling. This study investigated the roles of shaggy, an inhibitor of cWnt signaling, in regulating development in the tardigrade Hypsibius exemplaris. Gene expression patterns of shaggy and other components of the cWnt signaling pathway were analyzed alongside markers of anterior and posterior identity using Hybridization Chain Reaction in situ in H. exemplaris. RNA interference …

However, challenges that educators encounter while teaching spatial skills remain uncertain. The purpose of this study is to develop a research framework that examines the interrelationships, barriers, and enablers amongst various educational components, including schools, teachers, students, classrooms, and training programs, that are encountered when teaching for spatial ability development. A thorough examination of international research, in combination with a detailed review of the primary Science and Mathematics curricula in Ireland, Latvia, Sweden, and the Netherlands, is undertaken to …

The Joint Effects Of Cognitive Function And Sedentary Time On Mortality Risk In Older Adults: 2011-2014 Nhanes, Sarah A. Wilson

UNF Graduate Theses and Dissertations

Background: Examining the joint effects of cognitive function (CF) and sedentary time (ST) may provide insight into the complex mechanisms underlying mortality risk within older adults. This study examines the joint effects of CF and ST on mortality risk in older adults.

Methods: Sample included 2,230 older adults (≥ 60 years of age) participants in the 2011-2014 National Health and Nutrition Examination Survey. The Digit Symbol Substitution Test (DSST), Consortium to Establish a Registry for Alzheimer's Disease (CERAD) subtests, and Animal Fluency (AF) were used to assess CF. Average daily sitting and television time represented ST. Quartiles of CF and …

Implementation Of Algorithms For Sorting By Strip Swaps Using Alternating Cycle Graphs, Harsh S. Bhakharia

UNF Graduate Theses and Dissertations

Challenges in computational biology, such as genome rearrangement, and applications in optical character recognition, like zoning techniques, often require solving optimization problems. These involve reordering scrambled sequences of numbers into a sequential arrangement known as the identity permutation.

Rearranging any given permutation into the identity permutation with the minimum number of specific operations related to strips gives rise to various combinatorial optimization scenarios. Operations such as strip moves, transpositions, reversals, and block interchanges have been extensively researched.

This thesis builds on the foundational work of Roy et al., targeting the refinement of their cycle graph algorithm for sorting by strip …

The Perceptions Of Black Women In Principalships On Navigating And Negotiating The Racial Contexts Of Their Equity-Focused Leadership: A Q Methodology Study, Easter M. Brown

UNF Graduate Theses and Dissertations

One consequence of the Brown v. Board of Education (1954) ruling regarding desegregation of American public schools has been the destabilization of Black educators’ legacy of school leadership (Tillman, 2004). The effects of these failures continues to be problematic in US public education. Students of color account for over half of all P-12 enrollments, in contrast to the disproportionate lack of diversity among its teaching and leadership rosters (Frankenberg, et al., 2019; NCES, 2018, 2022). The stagnant rate at which American schools have diversified principal leadership since Brown v. Board (1954) begs the question of how equipped schools are to …

Organizational Support And Its Impact On Mental Health In Humanitarian Aid Volunteers, Valeria Prudnikova

UNF Graduate Theses and Dissertations

Humanitarian aid volunteers encounter a wide range of stressors, from witnessing horrific events and human suffering to facing organizational challenges and threats to their personal safety. These experiences can have significant and lasting impacts on their mental and emotional well-being. Despite increasing awareness of the psychological toll on aid volunteers, research on effective coping mechanisms and organizational support remains limited, while efforts by organizations that have begun implementing mental health training remain insufficient in providing the comprehensive, long-term support needed to mitigate these effects. This article aims to address the gap by reviewing existing literature on the psychological and emotional …

Influence Of Heat Treatment And Shielding Gas Environment On The Very High Cycle Fatigue Behavior Of 17-4 Precipitation Hardened Stainless Steel, Jade Welsh

UNF Graduate Theses and Dissertations

Additive manufacturing (AM) for stainless steel components has proved useful in a variety of industries ranging from aerospace to biomedical engineering. Many of these components are subject to very high cycle fatigue (VHCF) loading and must have tailored mechanical properties to ensure failures do not occur before a service life is reached. Testing the fatigue strength AM materials exposed to VHCF loading is paramount to compare with the expected life cycles of their wrought counterparts. In this thesis, AM 17-4 precipitation hardened (PH) stainless steel (SS) were fabricated using laser powder bed fusion (L-PBF) technique, while the wrought 17-4 PH …

Exploring Parental Engagement In A Family Stem Program Leveraging Social Media Spaces, Valentina Bongiovanni

UNF Graduate Theses and Dissertations

The Family Take-home STEM Toolkit Program offers families the opportunity to engage in science, technology, engineering, and mathematics (STEM) learning by utilizing the informal environments of the home and program-dedicated social media groups. This initiative provides a frame for this research, as parental engagement in the context of this early childhood program is explored through the lens of the Ecologies of Parental Engagement (EPE). This theoretical model understands engagement as the mediation of space and capital (Barton et al., 2004) and guides this study to further explore parental perceptions concerning the social media space activated with the STEM Toolkit Program. …

Understanding And Augmenting Scientific Software Testing Practices, Kris Roker

UNF Graduate Theses and Dissertations

Scientific software can be broadly defined as software written to aid in conducting scientific research activities. As this software is often written by the scientists themselves, who often learned programming to build that software, some important aspects of software development may get less attention than they would have gotten on enterprise software developed by programmers. One area of development that often gets overlooked in this regard is testing. Thus, in this study, we seek to better understand the testing processes and propose methods to improve the effectiveness of those tests. We begin with examining the software's Continuous Integration/Delivery practices. This …

A Model Defense Of Due Process Balancing, Kyron J. Huigens

Articles

Judicial balancing has been subjected to a standard list of objections for decades, without anyone's offering a comprehensive and persuasive response. This Article fills that gap. Balancing is not embedded in an invidious instrumentalism, such as utilitarianism, that saps law of its moral salience; it does not depend on the quantification or commensuration of manifestly qualitative legal interests; it is not arbitrary, result-oriented, or mere opinion; it does not invade the province of the legislature; and--most importantly--it does not risk balancing constitutional rights away by treating them as mere interests.

The defense consists of a model. Models do not prove; …

Improving The Affirmative Disclosure Of Agency Legal Materials, Bernard W. Bell, Cary Coglianese, Michael E. Herz, Margaret B. Kwoka, Orly Lobel

Articles

It is axiomatic that in a democratic society the law must be broadly accessible. Administrative agencies produce a plethora of materials imposing legal obligations on commercial or individual actors in the private sector. Other materials bind the agencies themselves in ways that affect the rights or interests of private parties. Still other materials provide the public with information about how agencies interpret and apply the statutes and rules they administer, or how agencies seek to deploy their discretion or take other actions that can affect private individuals or organizations. This Article focuses on improving the public availability of all of …

Foreclosure Sales As Fraudulent Transfers, David G. Carlson

Articles

The Supreme Court has declared that noncollusive, regularly conducted foreclosure sales are not “constructive” fraudulent transfers voidable by a bankruptcy trustee Uniform state legislation ratifies this instinct for private creditor enforcements. But collusive or irregular foreclosure sales or sales that are intended to hinder, delay, or defraud creditors are subject to creditor attack, even though unsecured creditors are not proper parties to the foreclosure process. In such cases, unsecured creditors can cloud the title obtained from foreclosure in the cases of collusion, irregularity or fraudulent intent. This article examines precisely when foreclosure sales can be avoided by unsecured creditors of …

International Survey On Opinions And Use Of Robot-Assisted And Laparoscopic Minimally Invasive Pancreatic Surgery: 5-Year Follow Up, Horacio Asbun

All Publications

Background: Evidence on the value of minimally invasive pancreatic surgery (MIPS) has been increasing but it is unclear how this has influenced the view of pancreatic surgeons on MIPS.

Methods: An anonymous survey was sent to members of eight international Hepato-Pancreato-Biliary Associations. Outcomes were compared with the 2016 international survey.

Results: Overall, 315 surgeons from 47 countries participated. The median volume of pancreatic resections per center was 70 (IQR 40-120). Most surgeons considered minimally invasive distal pancreatectomy (MIDP) superior to open (ODP) (94.6%) and open pancreatoduodenectomy (OPD) superior to minimally invasive (MIPD) (67.9%). Since 2016, there has been an increase …

Savings Associated With Surgical Aortic Valve Replacement With A Resilia Tissue Valve Based On Seven-Year Commence Trial Results, Tom Nguyen

All Publications

Background: Bioprostheses with RESILIA tissue demonstrate a reduction in calcification and improve health outcomes in pre-clinical and clinical studies. Prior economic analyses which relied on 5 years of evidence from the COMMENCE trial demonstrate financial savings for RESILIA tissue valves relative to mechanical valves after surgical aortic valve replacement (SAVR). Given the recent release of 7-year COMMENCE data, this economic evaluation updates the estimate for long-run savings of bioprosthetic valves with RESILIA.

Methods: Simulation models estimated disease progression across two hypothetical SAVR cohorts (tissue vs. mechanical) of 10,000 patients each in the US. The primary comparison calculated the SAVR-related expenditures …

"Don't Go Chasing Waterfalls": Fiduciary Duties In Venture Capital Backed Startups, Sarath Sanga, Eric L. Talley

Faculty Scholarship

We develop a model of venture capital contracting and use it to evaluate an emergent set of judicial precedents in corporate law, which we label the Trados doctrine. In our model, founders hold common stock, while venture capital investors hold convertible preferred stock. We show that preferred shareholders have inefficient incentives to liquidate low-valued firms and to continue high-valued firms, while common shareholders inefficiently favor the opposite. The extent of incentive misalignment depends on the firm’s intrinsic and outside valuations, and it is most severe around preferred shareholders’ liquidation preference and conversion point. Although legal liability rules can rectify these …

Public Primacy In Corporate Law, Dorothy S. Lund

Faculty Scholarship

This Article explores the malleability of agency theory by showing that it could be used to justify a “public primacy” standard for corporate law that would direct fiduciaries to promote the value of the corporation for the benefit of the public. Employing agency theory to describe the relationship between corporate management and the broader public sheds light on aspects of firm behavior, as well as the nature of state contracting with corporations. It also provides a lodestar for a possible future evolution of corporate law and governance: minimize the agency costs created by the divergence of interests between management and …

Transaction-Specific Tax Reform In Three Steps: The Case Of Constructive Ownership, Thomas J. Brennan, David M. Schizer

Faculty Scholarship

Similar investments are often taxed differently, rendering our system less efficient and fair. In principle, fundamental reforms could solve this problem, but they face familiar obstacles. So instead of major surgery, Congress usually responds with a Band-Aid, denying favorable treatment to some transactions, while preserving it for others. These loophole-plugging rules have become a staple of tax reform in recent years. But unfortunately, they often are ineffective or even counterproductive. How can Congress do better? As a case study, we analyze Section 1260, which targets a tax-advantaged way to invest in hedge funds. This analysis is especially timely because a …

Constitutional Clash: Labor, Capital, And Democracy, Kate Andrias

Faculty Scholarship

In the last few years, workers have engaged in organizing and strike activity at levels not seen in decades; state and local legislators have enacted innovative workplace and social welfare legislation; and the National Labor Relations Board has advanced ambitious new interpretations of its governing statute. Viewed collectively, these efforts — “labor’s” efforts for short — seek not only to redefine the contours of labor law. They also present an incipient challenge to our constitutional order. If realized, labor’s vision would extend democratic values, including freedom of speech and association, into the putatively private domain of the workplace. It would …

Courting Censorship, Philip A. Hamburger

Faculty Scholarship

Has Supreme Court doctrine invited censorship? Not deliberately, of course. Still, it must be asked whether current doctrine has courted censorship — in the same way one might speak of it courting disaster.

The Court has repeatedly declared its devotion to the freedom of speech, so the suggestion that its doctrines have failed to block censorship may seem surprising. The Court’s precedents, however, have left room for government suppression, even to the point of seeming to legitimize it.

This Article is especially critical of the state action doctrine best known from Blum v. Yaretsky. That doctrine mistakenly elevates coercion …

Comment On Part 4 Essays: Goodwin And Dailey And Rosenbury, Elizabeth S. Scott

Faculty Scholarship

Professors Michelle Goodwin and Anne Dailey and President Laura Rosenbury have written two compelling essays on Part 4 of the Restatement of Children and the Law, dealing with Children in Society. Goodwin’s essay, She’s So Exceptional: Rape and Incest Exceptions Post-Dobbs, focuses on § 19.02 of the Restatement, dealing with the right of minors to reproductive health treatments. This Section was approved by the American Law Institute before the Supreme Court decided Dobbs v. Jackson Women’s Health Organization, overturning Roe v. Wade. In her essay, Goodwin explores the harms that will follow if minors’ right of access …

The Harm Of "Nothing Burgers", Joshua Gupta-Kagan

Faculty Scholarship

Child protective services (CPS) agencies subject a wide scope of families to investigation, and the vast majority do not lead to family separations or family court cases. A 2017 study, for instance, showing that 37% of all children and 53% of Black children are the subject of CPS investigations in their childhoods, has now been cited hundreds of times. Kelley Fong’s new book, Investigating Families, is based on the months she spent embedded with CPS investigators responding to allegations that parents abused or (more often) neglected their children, and the interviews she conducted with both investigators and the parents …

Antisocial Innovation, Christopher Buccafusco, Samuel N. Weinstein

Articles

Innovation is a form of civic religion in the United States. In the popular imagination, innovators are heroic figures. Thomas Edison, Steve Jobs, and (for a while) Elizabeth Holmes were lauded for their vision and drive, and seen to embody the American spirit of invention and improvement. For their part, politicians rarely miss a chance to trumpet their vision for boosting innovative activity. Popular and political culture alike treat innovation as an unalloyed good. And the law is deeply committed to fostering innovation, spending billions of dollars a year to make sure society has enough of it. But this sunny …

Regulating Driving Automation Safety, Matthew Wansley

Articles

Over forty thousand people die in motor vehicle crashes in the United States each year, and over two million are injured. The careful deployment of driving automation systems could prevent many of these deaths and injuries, but only if it is accompanied by effective regulation. Conventional vehicle safety standards are inadequate because they can only test how technology performs in a controlled environment. To assess the safety of a driving automation system, regulators must observe how it performs in a range of unpredictable, real world edge cases. The National Highway Traffic Safety Administration (NHTSA) is trying to adapt by experimenting …

Book-And-Claim System For Sustainable Aviation Fuels, Christine Kranich, Sarah J. Haas

Journal of Air Law and Commerce

This Article provides an overview of the regulatory (legal) framework in which the decarbonisation of aviation is embedded, with a focus on European law. The Article further provides updates on EU-ETS, CORISA, RED III and the minimum quota of SAF supply in accordance with Refuel EU Aviation up to October 2023. Sustainable Aviation Fuels (SAF) will be described in detail in this Article, and it is further explained that the use of SAF could significantly contribute to aviation becoming “greener”. As the availability of SAF is still rather scarce, the Article revolves around a mechanism of a global book-and-claim system …

Still Far From Home – How Personal Jurisdiction Doctrine Undercuts The Montreal Convention’S “Fifth Jurisdiction” For “Wandering Americans”, Hans Huggler

Journal of Air Law and Commerce

The rapid growth of global air travel in the mid-20th century gave rise to the problem of the “wandering American”—American residents whose air travel injury claims could not be heard in United States courts under the Warsaw Convention’s Article 28. Prominent cases prompted adoption of a “fifth jurisdiction” in the Montreal Convention’s Article 33, allowing injury suits in the Contracting State where an injured passenger had her “principal and permanent residence” so long as the international carrier served the forum. U.S. officials toasted their success in providing Americans with a domestic forum, but the adoption of the fifth jurisdiction did …

Space ‘Tourism’: A Framework For Ensuring ‘Safe And Orderly Development’ Lessons Learnt From The U.S. And Aviation, Sarah J. Fox

Journal of Air Law and Commerce

In August 2023, following its successful mission, Virgin Galactic announced the intention to provide scheduled services into space. Yet, this paper sets out to present evidence to argue that, from an international (U.N.) perspective, there has been a lack of activity to establish safeguards and to ensure a fit for purpose governance and oversight mechanism is in place for this new and growing sector—space tourism. The research is undertaken by way of a comparison law/policy analysis which factors in key historic events across both aviation and space. The main focus is given to the developments and approach of …

O'Brien, Aisling A. Geraghty, Rosemary Cushion, Amy Gainfort, Rachel K. Crowley, Patrick J. Twomey, Ciara M. Mcdonnell, Fionnuala M. Mcauliffe

Articles

Background: Macrosomia (birthweight ≥4 kg) may alter the associations of physical activity (PA) and screen time (ST) throughout childhood with later cardiometabolic risk. Objective: To investigate associations of PA and ST over a 4–6-year follow-up period with cardiometabolic outcomes in preteens (9–11-year-olds) who were born to mothers with previous macrosomic delivery. Methods: This is an analysis of 402 preteens from the ROLO study, who were born to mothers that previously delivered an infant with macrosomia. Parental-reported measures of PA and ST were obtained in early childhood at 5-years of age. Preteen self-reported PA, parental-reported ST, anthropometry, dual-energy x-ray absorptiometry, blood …
