Lasa: Location-Aware Scheduling Algorithm In Industrial Iot Networks With Mobile Nodes, Marco Pettorali, Francesca Righetti, Carlo Vallati, Sajal K. Das, Giuseppe Anastasi

Computer Science Faculty Research & Creative Works

The Synchronized Single-hop Multiple Gateway (SHMG) is a framework recently proposed to support mobility into 6TiSCH, the standard network architecture defined for Industrial Internet of Things (IIoT) deployments. SHMG supports industrial applications with stringent requirements by adopting the Shared-Downstream Dedicated-Upstream (SD-DU) scheduling policy, which allocates to Mobile Nodes (MNs) a set of dedicated transmission opportunities for uplink data. Such allocation is performed on all the Border Routers (BRs) of the network without considering the location of MNs. Transmission opportunities are reserved also in BRs far from the current location of the MN, resulting in a waste of resources that limits …

Unintended Consequences Of Covid-19 Non-Pharmaceutical Interventions (Npis) For Population Health And Health Inequalities, Coilin Ohaiseadha, Gerry A. Quinn, Ronan Connolly, Awwad Wilson, Michael Connolly, Willie Soon, Paul Hynds

Articles

Since the start of the COVID-19 pandemic in early 2020, governments around the world have adopted an array of measures intended to control the transmission of the SARS-CoV-2 virus, using both pharmaceutical and non-pharmaceutical interventions (NPIs). NPIs are public health interventions that do not rely on vaccines or medicines and include policies such as lockdowns, stay-at-home orders, school closures, and travel restrictions. Although the intention was to slow viral transmission, emerging research indicates that these NPIs have also had unintended consequences for other aspects of public health. Hence, we conducted a narrative review of studies investigating these unintended consequences of …

Librarian Publications & Presentations

While there are many conferences for information workers, very few highlight the voices of marginalized identities and provide a platform for discussion for their research interests. According to a 2010 American Library Association survey, 88% of credentialed librarians identify as white. In our vision for this summit and the future of libraries, People of Color in Library and Information Science Summit at Loyola Marymount University encouraged the representation of diverse topics and perspectives and as a part of this work acknowledged that the racial disparities we see in the library and information science (LIS) field reflect inequities in other parts …

A Model Research Methods Training Program: Implications For The Curriculum, Kristine R. Brancolini, Marie Kennedy

Librarian Publications & Presentations

The majority of academic librarians in the US are employed by their insti-tutions either on tenure track, similar to teaching faculty, or they have some form of status that requires them to conduct and share the results of research to receive annual salary increases, achieve tenure or continuing employment, and/or gain promotion or enhanced ranking. Research published during the past two decades, however, confirms that most academic librarians enter the profession perceiving themselves to be unprepared for conducting research. To address deficiencies and alleviate anxieties surrounding research, the authors created a continuing educa-tion program for novice academic librarian researchers, the …

Correlates Of Christian Religious Identification And Deidentification Among Sexual And Gender Minorities: A U.S. Probability Sample, G. Tyler Lefevor, Lauren J. A. Bouton, Edward B. Davis, Samuel J. Skidmore, Ilan H. Meyer

Psychology Faculty Publications

Using a U.S. nationally representative sample of 1,529 sexual and gender minorities (SGMs), we examined the demographic and developmental correlates of Christian religious deidentification. We found that SGMs who were older, Black, cisgender men, and/or lived in the American South were more likely to identify as Christian in adulthood, relative to other SGMs. Those who were never Christian reported being more out to family and friends at earlier ages than those who were raised Christian. SGMs who were raised Christian, but did not identify as Christian in adulthood reported, more adverse childhood experiences and bullying than other SGMs. Sexual minorities …

Journeying Towards Connection In A Culture Circle With Six K-12 Educators: An Autoethnographic Study Of Critical Praxis, Christine Daniels

Theses & Dissertations

Critical praxis is an important means of increasing educators' critical consciousness. Culture circles are one avenue for educators to engage in a critical praxis, to dialogue, listen, reflect, and develop direct action steps. Both critical consciousness (Freire) and an ethic of care (Noddings) are essential and require an ongoing critical praxis. However, there is a lack of educational research on culture circles for ongoing praxis. In this auto/ethnographic, qualitative, action research (AR) study, the researcher created and explored a culture circle of six K-12 teachers. Over the course of five 90- minute sessions, the participants and the researcher raised situational …

Differences In Effectiveness Of Intrinsic And Extrinsic Motivation-Based Incentives In Promoting Use, Acceptance, And Adoption Of Automated Systems, Hannah M. Barr

Theses

This study examines the effectiveness of incentive mechanisms manipulating extrinsic and intrinsic motivation. Specifically, these incentives are used to promote use, acceptance, and adoption of an automated system in a simulated hostage-rescuing task. More frequent use of the automated system indicates increased acceptance and adoption. Participants are measured for how frequently they use the system. Participants also responded to questionnaires measuring their motivation, acceptance, and adoption. Bayesian ANOVAs are used to find differences in use, acceptance, and adoption between incentive mechanisms. It was expected that incentive mechanisms affecting intrinsic motivation will outperform incentive mechanisms affecting extrinsic motivation in promoting system …

Solar Flare Forecasting : A Study Of Flare Coincidence, Christian W. Hall

Theses

Data mining techniques that can support the forecasting of solar flares are explored. The main focus is to investigate the effects of flare coincidence on the evaluation of forecasts. Coincident flares are solar flares in a region of the Sun in which another flare has occurred recently, whereas other flares are denoted as non-coincident flares. Dimensionality reduction and classification are two of the types of techniques examined, where binary classification is used to issue yes/no forecasts of major solar flares. Five algorithms are considered as binary classifiers: k-nearest neighbors (k-NN), logistic regression (LR), support vector machines (SVM), random forest classifiers …

An Investigation Of Mission Designs To The Outer Solar System Supported By Centrifugal Nuclear Thermal Propulsion, William Ziehm

Theses

Centrifugal nuclear thermal propulsion (CNTP) has potential for supporting scientific missions to the outer solar system, shown by investigation of mission and vehicle architectures to the outer planets and Kuiper belt. The patched conic method provided initial guesses for numerical simulation and relationships between parameters of interest for trade studies, recommending engine performance parameters for missions supported by CNTP. Results of the patched conic model were validated by comparison to numerical results, which were within the expected variance for transit time with identical propellant margins based on literature. The trade studies gave a range of performance required to close rendezvous …

Extended, Exactly Solvable Chaotic Oscillator, Micah Tseng

Theses

Although the study of chaotic systems is theoretically mature for abounding examples, few are readily applicable to engineering problems. One notable barrier is the lack of analytic solution to guide or validate an engineered intention. In this thesis, a small set of chaotic systems known for their analytic solutions is expanded. Specifically, a known solvable second order solvable chaotic oscillator with a simple matched filter is extended such that the data rate is decoupled from the natural oscillation frequency of the oscillator. This development allows for high frequency applications without the need for high frequency switching. An extended, exact analytic …

The Impact Of Mkp-2 Deficiency On Hematological Parameters In Diet Challenged Mice, Cassandra Secunda

Theses

Mitogen-activated protein kinases (MAPKs) regulate metabolic homeostasis and MAPK dysfunction promotes metabolic diseases. MAPK phosphatases (MKPs) regulate MAPKs and are implicated in obesity and platelet activation. To elucidate the role of MKP-2 in platelet function and NAFLD, tail bleed, platelet isolation, and western blot assays were performed. MKP-2 KO mice and control mice were fed either a chow or 12- 13 week high fat diet (HFD), a 10 week iron deficient (ID), or an iron supplement (IS) regimen. On the chow diet, the bleeding time was significantly reduced in female MKP-2 KO mice. Male MKP-2 KO IS mice showed significantly …

Analysis Of Interconnected Subreddits On The Reddit Social Network, Lance Lindner

Theses

This thesis analyzes the Reddit social network to identify two aspects of interactions on that platform: (1) implicit leader-follower relationships, which are obtained by mining patterns of user interactions on the network and (2) highly “interconnected” subreddits which are obtained by scoring each subreddit using a “interconnectedness” value derived from the interaction patterns of users across subreddits. The data were obtained from Reddit in 2022 using a custom-built scrapper. This work analyzed 125,000 subreddits. The results show that the most highly connected subreddits on the Reddit network are ones that discuss content considered to be “not suitable for work” (NSFW). …

The Learning Agenda 2.0: An Approach To Facilitate Systems Change, Laura M. Lloyd, Melissa Alperin

Georgia Public Health Association Annual Meeting & Conference

Background: The public health (PH) workforce is currently facing many complex challenges that stand at the root of community health issues (e.g., racism, poverty, mental health). Existing PH workforce development models focus largely on improving individual competency, but individual competency alone cannot address these complex challenges at the individual, organizational, community, and systems levels. Developing the necessary cross-cutting skills (e.g., systems thinking, persuasive communication, problem solving) requires a new approach to training and learning.

Method: The Public Health Learning Agenda for Systems Change (PHLASC) helps public health organizations and their partners use transformative, collective learning as a driver for systems …

Analysis Of Hippo Pathway Signalling In Schwannoma And Meningioma, Julio Grimm De Guibert

Peninsula Medical School Theses

This project focuses on two tumours of the nervous system, schwannoma and meningioma. A large group of schwannomas and meningiomas display the inactivation of the NF2 gene. The NF2 gene codes for the tumour suppressor protein Merlin and its loss is associated with a multitude of pro-tumourigenic mechanisms leading to the occurrence of schwannomas and meningiomas. The loss of Merlin function causes augmented Hippo signaling i.e. interaction of YAP and TAZ, both co-activators of gene expression and the two main effectors of the Hippo signalling pathway, and TEAD, a group of transcription factors binding to YAP and TAZ. There resulting …

Investigation Of Microbiome Metabolites And Mitochondrial Function In A Model Of Non-Alcoholic Fatty Liver Disease, Paula Boeira

Peninsula Medical School Theses

Several dietary metabolites produced by gut bacteria have been linked to disease including non-alcoholic fatty liver disease (NAFLD). Trimethylamine N-oxide (TMAO) and phenylacetic acid (PAA) are microbiome-derived metabolites that have been associated with early onset of NAFLD. Hypothesising that these metabolites contribute to lipid deposition in the liver by altering hepatic mitochondrial function, we assessed how TMAO and PAA affect hepatocyte bioenergetics in cell models of liver steatosis. Proliferative and differentiated HepaRG cells were cultured under standard conditions, and steatosis was established by 48h exposure to oleate and palmitate (2:1 molar ratio). Lipid accumulation was assessed by BODIPY™ staining and …

Evaluation Of Mir-497 & Mir-219 As Non-Invasive Biomarkers For Meningioma And Glioma, Ahmed Abdelrahman

Peninsula Medical School Theses

Introduction: The current WHO classification aids in predicting meningioma and glioma recurrence and prognosis. However, there is a dearth of circulating biomarkers with clinical value for meningioma diagnosis and classification. Circulating miRNAs have shown potential as cancer biomarkers in various tumours. This study evaluated specific miRNAs, miR-497 and miR-219, as convenient and efficient predictors of meningioma and glioma grades. MiR-497 was selected based on preliminary results from Professor Hannemane's group, indicating its potential as a meningioma biomarker. MiR-219 was chosen because of its reported differential expression according to meningioma grade. Methods: Serum and exosomal levels of miR-497 were studied in …

Anastomotic Leakage In Rectal Surgery: Where Are We And Where Do We Go From Here?, Benjamin William Peter Rossi

Peninsula Medical School Theses

Anastomotic leak in colorectal surgery is a significant complication which is feared by surgeons and has considerable consequences for patients. It affects up to 17% of rectal resections and although there is significant knowledge regarding its detection and treatment, there are still no reliable methods for its prevention. We proposed the routine use of intra-operative endoscopy as a method of reducing the risk of anastomotic leak. This thesis explores current knowledge regarding anastomotic leaks, including the causes, prevention and management. We also present the findings from a feasibility trial into intra-operative endoscopy as a method for reducing anastomotic leak rate. …
