Combating Terrorism To Promote National Security In Nigeria: Libraries And Information Centres To The Rescue, Udemezue Joseph Ogugua, Jovita Amarachi Ikeagwuani Mrs

Library Philosophy and Practice (e-journal)

Terrorism is a hydra-headed monster and should be stamped out for the benefit of humanity. Fighting terrorism to enthrone national security should be at the front burner of government stakeholders especially this time that non-state actors operate with impunity. The paper discusses the role of libraries and information centres in combating terrorism and promoting national security in Nigeria. Specifically, the paper examines terrorism and national security, terrorism in Nigeria, the role of libraries and information centres in the fight against terrorism to promote national security. It also looks at the challenges encountered by libraries and information centres in the fight …

Beach Processes Controlling Erosional Hotspots And Their Influences On Beach Nourishment Performances: A Case Study Along West-Central Florida Barrier Island Beaches, Sophia Gutierrez

USF Tampa Graduate Theses and Dissertations

This study examines the long-term performance of repeated beach nourishment over an approximately 35-year period at two barrier islands, Sand Key and Treasure Island along the west-central Florida coast, USA. Five cycles of beach nourishment on Sand Key and six on Treasure Island were conducted during the study period. Three erosional hotspots were identified along a combined 14-km stretch of the nourished beach. The processes that cause the erosional hotspot were examined through numerical modeling of nearshore wave and current fields.

The most recent three nourishments since 2006 were monitored systematically by this study. Beach profiles were surveyed bimonthly to …

To characterise the social and economic dimensions of one of the world’s few long-standing sustainable shark fisheries.

Methods

We reviewed historic data and surveyed stakeholders to understand the economic and social dimensions of the shark fishery currently operating in Western Australia.

Key results

Since the fishery’s historic peak, there has been a substantial reduction in the number of operating vessels and ports due to management intervention. For the vessels that have remained, …

Radial Acceleration Relation Of Galaxies With Joint Kinematic And Weak-Lensing Data, Tobias Mistele, Stacy S. Mcgaugh

Faculty Scholarship

We combine kinematic and gravitational lensing data to construct the Radial Acceleration Relation (RAR) of galaxies over a large dynamic range. We improve on previous weak-lensing studies in two ways. First, we compute stellar masses using the same stellar population model as for the kinematic data. Second, we introduce a new method for converting excess surface density profiles to radial accelerations. This method is based on a new deprojection formula which is exact, computationally efficient, and gives smaller systematic uncertainties than previous methods. We find that the RAR inferred from weak-lensing data smoothly continues that inferred from kinematic data by …

Overlooked Psychometrics: An Examination Of The Construct Validity Of The Level Of Service/Case Management Inventory (Ls/Cmi), Agnieszka M. Nogalska

Student Theses

Construct validity is an important and under-examined source of evidence contributing to the psychometric properties of risk assessment instruments. This study assessed the construct and predictive validities of the LS/CMI examining a sample of 95 incarcerated male participants in the Northeastern United States. Results support a two-factor structure for the instrument, with the Criminal History, Education/Employment, Procriminal Attitude, and Antisocial Pattern subscales demonstrating convergence with other well-validated measures of these constructs. The results further suggest relatively weak discriminative ability for predicting recidivism (AUC = 0.67). Further research examining and integrating the construct and predictive validity of the LS/CMI specifically is …

Utilizing Hybrid Machine Learning Techniques And Gridded Precipitation Data For Advanced Discharge Simulation In Under-Monitored River Basins, Reza Morovati, Ozgur Kisi

Civil and Environmental Engineering Faculty Publications

This study addresses the challenge of utilizing incomplete long-term discharge data when using gridded precipitation datasets and data-driven modeling in Iran's Karkheh basin. The Multilayer Perceptron Neural Network (MLPNN), a rainfall-runoff (R-R) model, was applied, leveraging precipitation data from the Asian Precipitation—Highly Resolved Observational Data Integration Toward Evaluation (APHRODITE), Global Precipitation Climatology Center (GPCC), and Climatic Research Unit (CRU). The MLPNN was trained using the Levenberg–Marquardt algorithm and optimized with the Non-dominated Sorting Genetic Algorithm-II (NSGA-II). Input data were pre-processed through principal component analysis (PCA) and singular value decomposition (SVD). This study explored two scenarios: Scenario 1 (S1) used in …

Choosing Optimal Supply Radius Of Transformer Substations (Tss) In Iraq’S Cities Using Geometric Programming With Neutrosophic Coefficients, Ahmed K. Essa, Montifort Blessings Andrew Mitungwi, Tuweh Prince Gadama, Ahmed A. Salama

Neutrosophic Systems with Applications

Numerous uncertainties exist in various electricity power system problems due to the size, complexity, geographical distribution, and influence of unforeseen events in these systems, making it difficult for traditional mathematics tools based on crisp set theory to have an impact on and solve many power system problems. As a new branch of mathematical uncertainty techniques, the neutrosophic expert systems approach has therefore emerged with the development of electric power systems and has proven successful when correctly linked. The expert typically uses ambiguous or neutrosophic language to describe their empirical knowledge, such as "very likely," "quite likely," "if x is large, …

Subgroups Of Coxeter Groups And Stallings Foldings, Jake A. Murphy

LSU Doctoral Dissertations

For each finitely generated subgroup of a Coxeter group, we define a cell complex called a completion. We show that these completions characterizes the index and normality of the subgroup. We construct a completion corresponding to the intersection of two subgroups and use this construction to characterize malnormality of subgroups of right-angled Coxeter groups. Finally, we show that if a completion of a subgroup is finite, then the subgroup is quasiconvex. Using this, we show that certain reflection subgroups of a Coxeter are quasiconvex.

Analytic Wavefront Sets Of Spherical Distributions On The De Sitter Space, Iswarya Sitiraju

LSU Doctoral Dissertations

In this work, we determine the wavefront set of certain eigendistributions of the Laplace-Beltrami operator on the de Sitter space. Let G′ = O_1,n(R) be the Lorentz group, and let H′ = O_1,n−1(R) ⊂ G′ be its subset. The de Sitter space dSⁿ is a one-sheeted hyperboloid in R^1,n isomorphic to G′/H′. A spherical distribution is an H′-invariant eigendistribution of the Laplace-Beltrami operator on dSⁿ. The space of spherical distributions with eigenvalue λ, denoted by D_λ^H'(dSⁿ), has dimension 2. We construct a basis for the space of …

Thermal Frontal Polymerization – Applications In Coatings And Composites, Maria Martinez

LSU Doctoral Dissertations

Thermal frontal polymerization has long been used as a method to cure composites and coatings. However, this is the first time these applications have been used without the use of a catalyst, for the case of composites and coatings.

Chapter 2 discusses how to optimize cure-on-demand, thin layer coatings, using frontal polymerization. Previously, for the use of curing thin layer coating using thermal FP, it was known to just make the formulation viscous enough, as this would prevent premature quenching caused by heat loss. It was discovered that for a given layer thickness, a minimum viscosity and initiator concentration were …

Comparative Analysis Of Time Series Models On U.S. Stock And Exchange Rates: Bayesian Estimation Of Time Series Error Term Model Versus Machine Learning Approaches, Young Keun Yang

USF Tampa Graduate Theses and Dissertations

This study presents a comparative analysis of contemporary applications of time series models, focusing on the Bayesian approach. In contrast to many nonparametric studies, the Bayesian approach circumvents the common issue of bandwidth selection by offering systematic estimation and avoiding ad hoc methods. Specifically, we delve into the Bayesian approach for estimating the autocovariance function of a time series model’s error term. Traditional time series models often make the unrealistic assumption of a constant error term. Furthermore, models such as autoregressive conditional heteroskedasticity (ARCH) and general autoregressive conditional heteroskedasticity (GARCH) address the limitation of constant variance by assuming an autoregressive …

The Sacred And The Supernatural: Christianity And Teutonic Folklore In The Grimms’ Briar Rose, Amelia Stefanescu

Honors Theses

During the nineteenth century, the Brothers Grimm undertook the task of preserving German folklore during a time of cultural upheaval and struggle for national identity. One such tale, Briar Rose, emerges as a site of ideological interplay between Christian themes and Teutonic traditions. By analyzing the Grimms’ 1812 (first) and 1857 (last) editions, this thesis investigates how the text reflects and synthesizes these distinct belief systems into a coherent narrative.

The research explores how Christian and pagan elements co-exist within Briar Rose and what these interactions reveal about the cultural and religious dynamics within the folktale. The study argues that …

Exploration Of Characteristic Curve In Fox Float 3 Shock Dampers To Expedite Shock Damp Tuning., Joshua R. Moore

Honors College Theses

The shock absorber is an integral part of a vehicle suspension system and has a strong influence on its performance, especially in the case of motorsports. It is important to study the force versus velocity relationship, commonly known as the characteristic curve of the shock absorber both during compression and rebound. Vendor-supplied characteristics often reflect the behavior of the shock absorber in a particular setting. However, during the installation, the settings inside the shock absorber are adjusted to increase the human comfort level and performance of the vehicle. This may change the characteristic curve of the shock. The available data …

Vulnerability Assessment Of Urban And Peri-Urban Areas In Dhaka: Exploring Ecosystem Service Loss, Md Tousif Tanzir, Kh Shakibul Islam, Md. Raihanul Islam, Hasan M. Abdullah, Abdul Kaium Tuhin

Cities and the Environment (CATE)

Rapid unplanned development, a primary cause of urban change, endangers ecosystems greatly. Quantifying ecosystem services helps portray the declining ecological functions caused by the urban land cover change. Dhaka, one of the most densely populated cities in the world, exerts little effort toward sustainability; affecting both the inner city and the outer periphery (peri-urban area) called extend Dhaka (5 km buffer from the city's border). This study examines Dhaka's urban growth impact on ecosystem service values (ESV) from 2004-2020 and projects these impacts to 2050, considering three scenarios: business as usual (BAU), conservation, and development. We employed Landsat images, different …

The Importance Of Urban Eco-Gardens For Biodiversity And Human Sustainability: A Case Study From Palestine, Mazin B. Qumsiyeh, Mohammad H. Najajrah, Elias N. Handal, Johanna Gideon, Mohammed A. Abusarhan, Ruediger Prasse

Cities and the Environment (CATE)

The situation in Palestine is of concern where global threats of climate change, overexploitation, habitat destruction, invasive species, and pollution are compounded by occupation and conflict. Thus, almost 1/3^rd of vascular plant species are rare and over 50 are listed as endangered or rare based on their abundance and presence in grids studied earlier. Here, we describe the development of a conservation botanic garden that works via research, education, and direct in situ and ex situ conservation of plant species. The garden now boasts 381 species of vascular plants (63 are rare). The team scientifically and selectively introduced some …

Influence Of Community Characteristics On Urban Forest Management Programs In New York State, J. Rebecca Hargrave, Rick W. Harper, Brett J. Butler, Jamie T. Mullins

Cities and the Environment (CATE)

US state and federal urban forest management agencies endeavor to support municipal forestry programs. However, the variation in programs within and among states may complicate support delivery. Municipal programs are often categorized by population size and community affluence to identify common characteristics and needs and facilitate support. To describe local urban forest management programs in New York State, a survey of municipalities gathered information on urban forest management program components, intentions, and needs. In addition to examining the contributions of population size and affluence, this study also evaluated the influence of metropolitan areas on programs in small municipalities and compared …

The Modular Generalized Springer Correspondence For The Symplectic Group, Joseph Dorta

LSU Doctoral Dissertations

The Modular Generalized Springer Correspondence (MGSC), as developed by Achar, Juteau, Henderson, and Riche, stands as a significant extension of the early groundwork laid by Lusztig's Springer Correspondence in characteristic zero which provided crucial insights into the representation theory of finite groups of Lie type. Building upon Lusztig's work, a generalized version of the Springer Correspondence was later formulated to encompass broader contexts.

In the realm of modular representation theory, Juteau's efforts gave rise to the Modular Springer Correspondence, offering a framework to explore the interplay between algebraic geometry and representation theory in positive characteristic. Achar, Juteau, Henderson, and Riche …

Profiling Of Voltage-Gated Sodium Channel Subtype Expression And Resulting Susceptibility To Targeted Osmotic Lysis In Cancer, Spencer Gerard Lemoine

LSU Doctoral Dissertations

Cancer is a disease characterized by a wide array of dysregulated cellular function, activity, and growth. At times, specific dysregulations associated with cancer can be exploited as avenues of potential treatment. The sodium handling mechanisms and their associated proteins in cancer have received closer attention recently closely as such a potential mechanism to exploit for treating advanced cancer. Some novel treatments aim to inhibit the expression or activity of these sodium handling proteins in an attempt to prevent the cancer from advancing or becoming more aggressive; however, such approaches have had limited success. Targeted osmotic lysis (TOL) is a new …
