Post-Trial Responsibilities In Pragmatic Clinical Trials: Fulfilling The Promise Of Research To Drive Real-World Change, Stephanie R Morain, P Pearl O'Rourke, Joseph Ali, Vasiliki Rahimzadeh, Devon K Check, Hayden B Bosworth, Jeremy Sugarman

Center for Medical Ethics and Health Policy Staff Publications

While considerable scholarship has explored responsibilities owed to research participants at the conclusion of explanatory clinical trials, no guidance exists regarding responsibilities owed at the conclusion of a pragmatic clinical trial (PCT). Yet post-trial responsibilities in PCTs present distinct considerations from those emphasized in existing guidance and prior scholarship. Among these considerations include the responsibilities of the healthcare delivery systems in which PCTs are embedded, and decisions about implementation for interventions that demonstrate meaningful benefit following their integration into usual care settings-or deimplementation for those that fail to do so. In this article, we present an overview of prior scholarship …

Testing For Spatial Correlation Under A Complete Bipartite Network, Badi H. Baltagi, Long Liu

Center for Policy Research

This note shows that for a spatial regression with a weight matrix depicting a complete bipartite network, the Moran I test for zero spatial correlation is never rejected when the alternative is positive spatial correlation no matter how large the true value of the spatial correlation coefficient. In contrast, the null hypothesis of zero spatial correlation is always rejected (with probability one asymptotically) when the alternative is negative spatial correlation and the true value of the spatial correlation coefficient is near -1.

Reinforcement Learning For Strategic Airport Slot Scheduling: Analysis Of State Observations And Reward Designs, Anh Nguyen-Duy, Duc-Thinh Pham, Jian-Yi Lye, Nguyen Binh Duong Ta

Research Collection School Of Computing and Information Systems

Due to the NP-hard nature, the strategic airport slot scheduling problem is calling for exploring sub-optimal approaches, such as heuristics and learning-based approaches. Moreover, the continuous increase in air traffic demand requires approaches that can work well in new scenarios. While heuristics rely on a fixed set of rules, which limits the ability to explore new solutions, Reinforcement Learning offers a versatile framework to automate the search and generalize to unseen scenarios. Finding a suitable state observation and reward structure design is essential in using Reinforcement Learning. In this paper, we investigate the impact of providing the Reinforcement Learning agent …

Examining Dietary Disparities And Associated Factors Among Young Children Across Diverse Racial, Ethnic And Immigrant Households In Nebraska, Naveta Bhatti

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Early childhood is a crucial stage for developing eating behaviors which in turn plays a major role in determining health outcomes. Assessing children’s diet plays a crucial role in tackling the obesity epidemic. One of the ways to assess children’s dietary intake is by evaluating their dietary quality. Dietary quality refers to the overall healthfulness and nutritional value of an individual's diet, considering the combination of foods consumed over time. Research has consistently demonstrated that a high-quality diet is associated with a reduced risk of several health issues, such as all-cause mortality, cardiovascular disease incidence or mortality, cancer incidence or …

The Road To Tailored Adjuvant Chemotherapy For All Four Non-Pancreatic Periampullary Cancers: An International Multimethod Cohort Study, Bas A Uijterwijk, Daniël H Lemmers, Michele Ghidini, Johanna W Wilmink, Alberto Zaniboni, Giuseppe Kito Fusai, Alessandro Zerbi, Bas Groot Koerkamp, Misha Luyer, Poya Ghorbani, Roberto Salvia, Steven White, Benedetto Ielpo, Brian K P Goh, Ugo Boggi, Geert Kazemier, Michael G House, Vasileios K Mavroeidis, Bergthor Björnsson, Michele Mazzola, Mario Serradilla, Dimitris Korkolis, Adnan Alseidi, Keith J Roberts, Zahir Soonawalla, Patrick Pessaux, William E Fisher, Sharnice Koek, Tara S Kent, Miljana Vladimirov, Louisa Bolm, Nigel Jamieson, Raffaele Dalla Valle, Jorg Kleeff, Alessandro Mazzotta, Miguel Angel Suarez Muñoz, Santiago Sánchez Cabús, Chad G Ball, Adam C Berger, Clarissa Ferarri, Marc G Besselink, Mohammed Abu Hilal, International Study Group On Non-Pancreatic Periampullary Cancer (Isgaca)

Center for Medical Ethics and Health Policy Staff Publications

Background: Despite differences in tumour behaviour and characteristics between duodenal adenocarcinoma (DAC), the intestinal (AmpIT) and pancreatobiliary (AmpPB) subtype of ampullary adenocarcinoma and distal cholangiocarcinoma (dCCA), the effect of adjuvant chemotherapy (ACT) on these cancers, as well as the optimal ACT regimen, has not been comprehensively assessed. This study aims to assess the influence of tailored ACT on DAC, dCCA, AmpIT, and AmpPB.

Patients and methods: Patients after pancreatoduodenectomy for non-pancreatic periampullary adenocarcinoma were identified and collected from 36 tertiary centres between 2010 - 2021. Per non-pancreatic periampullary tumour type, the effect of adjuvant chemotherapy and the main relevant regimens …

Privacy-Preserving Arbitrary Geometric Range Query In Mobile Internet Of Vehicles, Yinbin Miao, Lin Song, Xinghua Li, Hongwei Li, Kim-Kwang Raymond Choo, Robert H. Deng

Research Collection School Of Computing and Information Systems

The mobile Internet of Vehicles (IoVs) has great potential for intelligent transportation, and creates spatial data query demands to realize the value of data. Outsourcing spatial data to a cloud server eliminates the need for local computation and storage, but it leads to data security and privacy threats caused by untrusted third-parties. Existing privacy-preserving spatial range query solutions based on Homomorphic Encryption (HE) have been developed to increase security. However, in the single server model, the private key is held by the query user, which incurs high computation and communication burdens on query users due to multiple rounds of interactions. …

An Examination Of The Perceptions Of Campus Safety Among Full-Time Faculty At Virginia Community Colleges, Hailey Ann Hermosa

Educational Leadership & Workforce Development Theses & Dissertations

The view that colleges are generally safe has been challenged by threats of violence on campuses across the country, causing fear among stakeholders. Community college faculty are not immune to crime-related fear on campus; however, the research has largely ignored this population. This research serves to fill that gap.

The purpose of this nonexperimental quantitative study was to examine perceptions of campus safety among full-time faculty at Virginia community colleges. An electronic Likert-type scale survey was disseminated to a sample of 472 full-time faculty throughout seven Virginia community colleges of varying sizes. Of those, 135 (28.7%) voluntarily participated in the …

Bridging The Nature-Cultural Heritage Gap: Evaluating Sustainable Entanglements Through Cemeteries In Urban Asia, David Ocon, Wei Ping Young

Research Collection School of Social Sciences

The expanding footprint of urban Asian settlements and increasing living standards have put pressure on cemetery sites. Public health narratives and the sanctity associated with death matters in Asian urban landscapes have fed into the rhetoric of cemeteries as undesirable heritage spaces. Often lacking protection, many cemeteries have been exhumed, cleared, and relocated to allow room for new developments and infrastructure, risking the survival of this quiet element of the urban cultural patrimony. Within an Asian context, synergies between nature and cultural heritage preservation are not prevalent in major cities like Singapore, Hong Kong, Tokyo, Manila, Kuala Lumpur, and Bangkok. …

Transportation, Healthcare Seeking, And Outcomes, Xiao Lin Ong

Dissertations and Theses Collection (Open Access)

Advancements in engineering and transportation technology have integrated commuting into modern living. Most studies on transportation infrastructure, such as roads and railways, focus on economic outcomes. This paper examines an overlooked outcome of transportation connectivity: access to medical care. We study the role transportation networks play in determining patients’ treatment location choices. Specifically, we aim to study 1) why patients travel to begin with, 2) how do patients choose where to go for treatment, and 3) how travel times can affect patients’ travel decisions. To do so, we develop a dynamic discrete choice, spatial model and provide empirical estimates. We …

Insourcing The Smart City: Assembling An Ideo-Technical Ecosystem Of Talent, Skills, And Civic-Mindedness In Singapore, Orlando Woods, Tim Bunnell, Lily Kong

Research Collection College of Integrative Studies

This article examines an alternative model of smart city formation, one based on the principle of insourcing technical competencies and capabilities to those responsible for city governance. This model counters the logic of technological outsourcing upon which many assumptions and critiques of the smart city rest, and thus reveals ways in which a more generative discourse can be forged. Drawing on a series of in-depth interviews with senior stakeholders from public and private sector organizations, we develop a case study of Singapore’s Smart Nation initiative. Through coordinated efforts to reorganize the public sector’s technological functions, develop nation-wide skills upgrading programs, …

Impact Of Rainfall On Air Temperature, Humidity And Thermal Comfort In Tropical Urban Parks, Juan A. Acero, Philip Carl Kestel, Hieu T. Dang, Leslie K. Norford

Research Collection College of Integrative Studies

Urban areas in hot and humid tropical regions are frequently exposed to uncomfortable thermal levels. A well-developed urban heat mitigation strategy is increasing vegetation infrastructure, even though the impact differs based on regional climate. In this study we have evaluated the impact of rainfall on air temperature, humidity and thermal comfort inside a large urban park in Singapore, based on measurement campaigns. A comparison between the park and an urban site is presented. Results show that rainfall significantly reduces air temperature and improves thermal comfort levels, not only right after the rain event but also in the after-event dry period. …

Fine-Grained Passenger Load Prediction Inside Metro Network Via Smart Card Data, Xiancai Tian, Chen Zhang, Baihua Zheng

Research Collection School Of Computing and Information Systems

Metro system serves as the backbone for urban public transportation. Accurate passenger load prediction for the metro system plays a crucial role in metro service quality improvement, such as helping operators schedule train timetables and passengers plan their trips. However, existing works can only predict low-grained passenger flows of origin-destination (O-D) paths or inflows/outflows of each station but cannot predict passenger load distribution over the whole metro network. To this end, this paper proposes an end-to-end inference framework, PIPE, for passenger load prediction of every metro segment between two adjacent stations, by only utilizing smart card data. In particular, PIPE …

Readability And Suitability Of Local Disaster Preparedness Materials In Predominantly Hispanic Border Communities: A Case Study Of Cameron County, Texas, Katarzyna Sepielak, Dawid K. Wladyka

Sociology Faculty Publications

Community awareness is a key component of disaster resilience and numerous agencies developed a plethora of preparedness materials. Previous studies evaluated national-level resources and social media content indicating that these efforts are not effectively reaching vulnerable populations, as the information is provided at or above the secondary education level. However, the local-specific content has been mostly overlooked in the analyses, subsequently neglecting the needs of areas with specific demographics and hazards, like predominantly Hispanic border communities. Thus, this study turns to local preparedness and mitigation materials, rather than general internet searches or national level documents. We analyze information provided on …

No Limits: The Inside Story Of China’S War With The West, Thomas F. Lynch

Joint Force Quarterly

No Limits: The Inside Story of China’s War With the West is a valuable book. It is simultaneously analytical and personal. No Limits is an incisive, selective history about how the promise of China’s integration into Western economic systems and global institutions gave way to acrimony and rivalry. It also is author Andrew Small’s memoir about how his quarter-century-long iterative interactions with China evolved from hope and cautious optimism about Sino-global integration into resigned fatalism that the Chinese Communist Party (CCP) can never tolerate such a happy ending. The CCP must instead view itself as perpetual victim and implacable rival …

Airpower In The War Against Isis, Charles J. Dunlap

Joint Force Quarterly

In Airpower in the War Against ISIS, Benjamin Lambeth not only weaves an account that celebrates the decisive role he insists airpower played in the defeat of the so-called Islamic State (IS) but also depicts tragically missed opportunities and almost incomprehensibly poor judgment on the part of U.S. civilian and military leaders that unnecessarily delayed that defeat.

Converting A Political- To A Military-Strategic Objective, Milan Vego

Joint Force Quarterly

Political objectives are usually achieved by using one’s military power. Converting political objectives into achievable military-strategic objectives is the primary responsibility of military-strategic leadership. This process is largely an art rather than a science. There are many potential pitfalls because much depends on the knowledge, understanding, experience, and judgment of military-strategic leaders. Most often, mistakes made are only recognized after setbacks or defeats suffered during the hostilities. Despite its critical importance, there is no consensus on the steps and methods in converting political- into military-strategic objectives. There is scant writing on the subject in either doctrinal documents or professional journals.

Navigating The Unintended Consequences Of Language, Imagery, And Meaning Has Never Been More Difficult Or More Important, Jon Brown

The Journal of Conventional Weapons Destruction

Words matter. The imagery we use matters. When we tell the wrong story (or the right story in the wrong way), it damages us as organizations, damages us as a sector, and, most importantly of all, causes distant but lasting harm to the very communities we exist to serve and of which we are a part of. Let’s be clear: we at Mines Advisory Group (MAG) are certainly as guilty as the rest of the sector in getting things wrong, but we are putting steps in place to try to get it right.

What Can Artificial Intelligence Offer Humanitarian Mine Action?, Russell Gasser Ph.D.

The Journal of Conventional Weapons Destruction

Would you walk on land declared safe by an unproven technology, developed by enthusiastic proponents who do not have long experience in the world of mine action? What if the system for locating hazards will be tested in only one or two trials, even though the type of machine learning system they are using is known to sometimes give false but completely plausible results (so-called hallucinations1)? Furthermore, in the proposed machine-learning system there will be no audit trail for analysis if a serious error occurs, and no way of knowing for sure how to prevent its repetition.

Mission (Command) Complete: Implications Of Jadc2, Joseph M. Mcgiffin

Joint Force Quarterly

Command and control (C2) is crucial in military operations, guiding how authority directs missions. As warfare evolves with AI, hypersonic weapons, and autonomous platforms, the U.S. military is advancing its Joint All-Domain Command and Control (JADC) initiatives. This effort aims to unify military networks for better decision-making. This article explores challenges in adapting Joint C2 networks for JADC2. It compares new technologies with current military practices, highlighting where changes are needed. Key areas include strategic planning, tactical operations, and how JADC2 affects mission command. Recommendations focus on improving readiness for future conflicts by enhancing interoperability and decision-making across military branches.

The Other Arctic: Competition, Cooperation, Or Coexistence?, John B. Kelley, Christopher J. Sarton, Scott A. Curtice, Charles C. York Iii

Joint Force Quarterly

In Antarctica, the United States must mitigate risks stemming from competitive influences working to alter the current paradigms, but it also should seize the opportunities that Antarctica’s unique status affords. As climate change continues to open new opportunities in polar regions, international concern has grown over the potential for the future irresponsible use of the area by actors more concerned with military and economic advantage than conservation efforts. Apprehension over the People’s Republic of China (PRC)’s activities raises more significant concerns that Antarctica may become a region of military competition instead of global cooperation. This apprehension is well-founded but not …

Culture Or Power: The Eruption Of The Anglophone Crisis In Cameroon, Danielle Tagakou Talla

Dissertations and Theses

Located in Central West Africa, Cameroon has been the stage of a protracted conflict since 2016. The conflict called the "Anglophone crisis" is rooted in Cameroon colonial history. This is reflected in the composition of its population with a large majority of Francophones and only 20 percent of Anglophones. The subsequent thesis aims to examine the crisis between 2016 and 2022 and understand the shift in focus that happened in the early years of the conflict. Using a qualitative methodology, journal articles, books and recorded interviews will provide substantial sources to decipher the change from cultural focus to one of …

Understanding The Relationship Between Teacher Turnover And Student Success Across Ethno-Racial And Socioeconomic Demographics: An Analysis Of Massachusetts Public Schools, Jenna O'Leary

Master's Theses

Teacher turnover in the U.S. has risen over the past decades. Urban districts have faced some of the highest rates of turnover amongst their staff. However, scholars still debate the impacts of teacher turnover on student academic success. This study aims to better understand this relationship across both ethno-racial and socioeconomic student demographics, as well as school region type. To accomplish this, student test scores, across demographics, on the Next Generation MCAS state standardized test are observed in relation to teacher retention across three year cycles (2016-2017, 2017-2018, 2018-2019). Using correlation analysis and t-tests, it is found that there is …
