Knowledge, Attitudes, And Practices Among Hepatitis B Patients In Jakarta, Indonesia: A Cross-Sectional Study, Hashem S. Arkok, Tri Yunis Miko Wahyono, Nurhayati Adnan Prihartono, Dipo Aldila

Kesmas

Hepatitis B remains a major public health problem in Indonesia. This study assessed the knowledge, attitudes, and practices (KAP) of hepatitis B patients in Jakarta to identify gaps in prevention and control and to explore relationships among KAP components. A cross-sectional study was conducted among 128 patients at a government hospital in South Jakarta, using a structured questionnaire that collected demographic information and assessed knowledge, attitudes, and practices regarding hepatitis B transmission and prevention. Despite moderate knowledge levels, major gaps remained. Only a small proportion (10.9%) correctly identified common symptoms, transmission routes (10.2%), and possible complications (18.8%). Misconceptions about transmission …

The Statistical Distribution Of U.S. Corn And Soybean Futures Prices, Chiamaka D. Osigwe

LSU Master's Theses

This thesis investigates the best-fit empirical distribution for daily U.S. corn and soybean futures price changes and examines how distributional choices affect Value-at-Risk (VaR) and Expected Shortfall (ES) estimates. The dataset comprises daily nearby futures prices for corn (11/16/1994–04/23/2025) and soybeans (10/16/1979–02/15/2023), yielding 7,626 and 10,853 observations, respectively. An ARCH-LM test confirms the presence of Autoregressive Conditional Heteroskedasticity (ARCH). Generalized Autoregressive Conditional Heteroskedasticity (GARCH) models were estimated, and to account for potential asymmetric effects, an EGARCH model was used. EGARCH (1,1) estimation reveals an inverse leverage effect, where positive price shocks generate higher volatility. Six heavy-tailed distributions were evaluated, and …

A New Hybrid Approach For Magnetohydrodynamic Flow Over A Stretching Surface With Nanofluid, Ammar Al-Salih, Abdul-Sattar Jaber Al-Saif

Baghdad Science Journal

The current investigation focuses on developing a semi-analytical technique aimed at estimating the solutions of magnetohydrodynamics flow with Casson tri-hybrid nanofluid (TiO₂ - SiO₂ - Al₂O₃/blood) flowing over a stretchable surface along two-dimensional space. To solve the obtained nonlinear coupled differential equations in the problem formulation, the proposed semi-analytical approach makes use of the Shehu reduced differential transform Padé method (SRDTPM). Several physical parameters, such as slip effect, porosity, magnetic strength, and Casson number, were considered for examining the effect on momentum, while radiation parameter, heat generation/absorption, temperature-dependent heat sink/source term, and Biot number …

Transportation Deserts And Structural Mobility Access In New York City, John Cruz

Student Theses

This study examines structural mobility access across New York City census tracts by constructing a tract-level Mobility Access Index (MAI) that integrates employment accessibility, hospital accessibility, and first-mile subway walking burden using MTA GTFS transit data, NYC Taxi and Limousine Commission trip records, and US Census American Community Survey demographic estimates. Three OLS regression models, supplemented by Lasso, Elastic Net, and Random Forest specifications, test whether structural access gaps are associated with short-distance connector trip intensity and per-worker connector cost burden. Results show that MAI varies substantially across tracts, with high access concentrated in Manhattan and along major subway corridors. …

Parent Perspectives On Primary And Secondary Online Learning, Barbara Tanner Sandberg

Theses and Dissertations

Given the growth of K-12 online learning and the expanded responsibilities parents often assume in this learning context, the purpose of this dissertation is to understand parents' perspectives on K-12 online learning. The first article reviews and synthesizes literature documenting parents' perspectives on how instructional modality affects parental support. Instructional modality affects parental support roles, parental perception of online school support, parents' lives outside the online course, and students' online learning support needs. Hence, parents expect modality decisions to account for modality affordances, student engagement, and personal circumstances. The second article examines parent perspectives on the decision to leave a …

The Disconnect In Female Labour Force Participation Policy In Egypt: Design And Implementation Gaps, Miral Mohamed Omran

Theses and Dissertations

This study investigates the disconnect between Egypt's ambitious female labor force participation (FLFP) policy goals in the National Strategy for the Empowerment of Egyptian Women 2030 and the declining indicators since its launch. Applying Van Meter and Van Horn's implementation framework, it analyzes the full policy process using qualitative interviews across government, civil society, and private sector actors involved in the national policy’s design and execution. Findings reveal structural failures, resource shortages, coordination gaps, leadership turnover, and donor-driven fragmentation, intensified by cultural norms and frontline resistance. Recommendations prioritize short-term administrative tweaks leveraging public sector downsizing for harmonization and rethinking the …

Three-Dimensional Shape Cues Affect Human And Artificial Recognition Systems Differently, Mikayla Cutler, Luke D. Baumel, Joseph Tocco, William Friebel, George K. Thiruvathukal, Nicholas Baker Dr.

Computer Science: Faculty Publications and Other Works

Humans and neural networks use shape and texture information differently. While humans weigh shape heavily in their ultimate classification decision, neural networks are more biased towards texture cues. Many tests of shape vs. texture bias have focused on shape recognition from an object’s external contour. However, shape information is also conveyed through internal contours, shading, and attached shadows, especially when an object is viewed from noncanonical perspectives. Using models from ShapeNet, we created datasets of 120,000 texture-substituted images of objects from many viewpoints with and without shading and attached shadows. We tested humans’ and several neural networks’ ability to classify …

Classification Of Phishing Data Using Hybrid Mi-An Feature Selection Method, Damodar Patel, Amit Kumar Saxena, Wutiphol Sintunavarat, Abhishek Dubey

Baghdad Science Journal

Web phishing attacks have been continually evolving over the past few years, which has led customers to lose their trust in online services and e-commerce. To identify phishing data, a variety of methods and systems based on a blacklist of phishing websites are used. However, the rapid development of technology has given rise to increasingly complex techniques for creating user-attracting websites. Therefore, current blacklist-based techniques are unable to identify the recently launched phishing data, such as zero-day phishing websites. Machine learning techniques have been used in several recent studies to detect phishing data and function as an early warning system …

New Generalizations Of Pairwise Lindelöf Spaces, Hana M. Binshahnah, A. K. Mousa

Baghdad Science Journal

This study is introducing two new different pairwise related to Lindelöf bitopological spaces. Lindelöf spaces are among of the most important topological spaces with important applications in various branches of mathematics. Therefore, many studies on Lindelöf topological spaces and pairwise Lindelöf bitopological spaces were presented in previous papers. However, those two new pairwise Lindelöf bitopological spaces are more general than what has been studied before. Therefore, the study defines a new pairwise interior operator and a new pairwise closure operator, furthermore, it reviews their characteristics where the researchers provide new strongly pairwise axioms (the strongly pairwise regular and the strongly …

Generalization Of Prolla's Theorem In Approximation, Nadia M. J. Ibrahem, Salwa Salman Abed, Shaimaa S Albundi

Baghdad Science Journal

The principal factor in the proofs of many so-called intersection results and associated best approximation theorems—such as the famed Brouwer fixed-point theorem) is Knaster-Kuratowski-Mazurkiewicz theorem (KKM), which was extended from R^l to Hausdorff vector spaces by Ky Fan. This kind of theory necessitates introducing some form of abstract convex structure on a topological space. In both pure and applied mathematics, the theory of approximation plays a central role. The connection between best approximation and fixed-point theory provides a powerful tool for analyzing the nonlinear maps, the convergence of iterative processes, and the solving of variational …

Does Patient History Influence Capsular Contracture? An Exploratory Analysis With Machine Learning, Thomas M. Johnstone, Daniel Najafali, Jennifer K. Shaw, Justin M. Camacho, Chancellor Johnstone, Rahim S. Nazerali, Gordon K. Lee

Faculty Publications

Background: Capsular contracture (CC) is a frequent and distressing complication of breast augmentation and reconstruction. Although numerous patient-, surgical-, and implant-related risk factors have been proposed, reliable population-level predictors remain inconsistent across studies. This study evaluates whether administrative medical history, as encoded by ICD and CPT codes, contains sufficient predictive signal to identify patients at risk for CC using machine learning. Methods: Patients were queried from the MerativeTM MarketScan® Research Databases from 2003 to 2017 with CPT codes for implant-based breast reconstruction and augmentation. ICD codes were then used to identify all events and conditions of a patient’s history. Hyperparameter-tuned …

The Voice As The Ultimate Microtonal Instrument, Catherine Terrell

University Honors Theses

I wrote several songs in a non-standard tuning system, 19-equal temperament. I define and distinguish 19-equal temperament and 12-equal temperament, then explore why I decided to write in this tuning system. I argue that intonation is a tool composers can implement along with more common musical devices. After describing the methods I used to create this music, I detail how I taught performers to sing it. I then describe and analyze the several works of music I created. Through the compositional process, I found tuning to be a very effective means in expressing musical and poetic ideas.

Summer Dormancy In Italian Populations Of Dactylis Glomerata L., F Lorenzetti, A Panella, E Falistocco

IGC Proceedings (1977-2023)

Mediterranean types of perennial grasses are winter-growing and summer-dormant, while central and northern European types arc winter-dormant and aummer•growing. Dormancy severely limits the annual production and largely determines the seasonal distribution pattern of the perennial grass. Summer dormancy wa• studied in 81 Italian populations of Dac!)llit glomtTata. L. collected from north (48°N) to south (38°N) on the Italian pt:ninaula. Dormancy was measured at Perugia (43°O5'N) on 60 plant.'i for each population. The percentage of summer-dormant plants was negatively correlated with the mean score for summer growth (r = -0.75**). The results distinguish three main groups of populations with increasing levels …

Growth And Development Of Two Echinochloa Millet Species In A Warm Temperate Climate, D K. Muldoon

IGC Proceedings (1977-2023)

Most summer forage crops fall into either the sorghum or the millet species group. Included in the millet group are two species, Echinochloa utilis and Echinochloa frumentacea, commonly known as Japanese barnyard millet and Indian barnyard millet, respectively. These species have a negligible HCN potential and higher nutritive value than Sorghum species. However, they generally flower early, yield less than forage sorghum , and lack vigor in regrowth. In this study the pattern of growth and development of two Echinochloa millets was examined as part of a larger program of improving the production of these forage species. E. utilis …

Test Adaptation And Evaluation Trials Of Forage Plants In Major Ecological Regions Of Ethiopia And Kenya, K M. Ibrahim, A Orodho

IGC Proceedings (1977-2023)

Kenyan and Ethiopian natural grazing Ian.cl. support more than 20% of the cattle population of the African continent. Many of the natural pastures of these countries are severely overgrazed, as unfavorable grazing conditions prevail for over half the year. Objectives of adaptation trials were to evaluate and identify introduced or indigenous forage and fodder species or ecotypes having genetic potential for high production of digestible dry matter for direct pasture and range improvement and for future use in breeding programs. Over 4,000 indigenous and 3,000 introduced ecotypes were evaluated for 24 vegetative characters in six ecological regions between 1971 and …

Collections Of Western Wheatgrass And Blue Grama And Associated Nematode Genera In The Western Dakotas, R E. Barker, J D. Berdahl, J M. Krupinsky, E T. Jacobson

IGC Proceedings (1977-2023)

Western wheatgrass (Agropyron smithii Rydb.) and blue grama (Bouteloua gracilis[Willd. ex H.B.K.J Lag. ex Griffiths) are widely distributed throughout the U.S.A. They arc two of the predominant native grasses in rangelands in the northern Great Plains. Because suitable cultivars are not always available for reseeding disturbed areas, we collected plants of the two species and evaluated phenotypic variability to determine potential for breeding improvement. We also sampled the nematode popula­tion associated with the collections. Sampling sites were systematically chosen by establishing a grid pattern 19 .3 km apart in the western halves of North Dakota and South Dakota. …

0.42-mm screen. Plots were harvested four times during each of the first 2 years and five times in the third year. In 1977-1978 and 1978-1979, NDF and protein analyses were run on samples from 2 replications. All forage samples were analyzed for pro­tein via the micro-Kjeldahl technique. Percentages of NDF were obtained via Van Soest extraction procedures. A seasonal increase in neutral detergent fiber (NDF) content and a decrease in protein percentage was observed. Differences in NDF were observed among cultivars and were most apparent during …

Forage Quality Of Barley Straw As Influenced By Genotype, D W. Meyer, D O. Erickson, A E. Foster

IGC Proceedings (1977-2023)

Cereal straw is an untapped carbohydrate source for ruminant animal feeds, but little information is available on genotypic differences in the feeding value of barleys (Hordeum vulgare L.) commonly grown in the northern Great Plains of the U.S.A. Our objective was to determine if barley genotypes differ in straw forage quality and if straw-quality parameters are associated with agronomic characters. Straw from 37 and 31 barley genotypes was sampled in 1977 and 1978, respectively. Straw from 10 barley genotypes grown at four locations was sampled in 1979. Standard laboratory procedures were used to determine the quality parameters measured. Correlations …

Productivity Of Forage Legumes On Rice-Paddy Walls In Northeast Thailand, R G. Gutteridge

IGC Proceedings (1977-2023)

Rice stubble left standing in paddy fields after rice harvest is the major source of forage for livestock in the dry season in northeast Thailand. Although the quantity of thi5 1tubble is generally not limiting, its quality as a forage is very low, and substantial live-weight losses in livestock usually occur by the end of the dry season. A trial was conducted to evaluate a range of forage legumes that could be grown on rice-paddy walls to supplement rice stubble as a dry-season feed. Seven legumes were planted at two sites in villages close to Khon Kaen in northeast Thailand. …

Development Of Gama Medic {Medicago Rugosa Desr.) As An Annual Leguminous Species For Dryland Farming Systems In Southern Australia, E J. Crawford

IGC Proceedings (1977-2023)

Annual medics (Medicago spp.) are the basic legume for nitrogen fixation in the alkaline soils of southern Australia. Not all in­dividual species are well adapted to all soil types, one difficult soil being the highly alkaline clay loam where annual rainfall is less than 500 mm. The first gama medic (M. rugosa) cultivar, Paragosa, was well adapted to the clay-loam soil type but proved to be susceptible to germination after summer thunderstorms, and seedlings died in the following drought. Many gama medic accessions were then grown in an attempt to select a genotype capable of maintaining seedcoat impermeability during …
