Teachers’ Awareness Of Family Engagement In Multilingual Education, Sedighe Zamani Roodsari

Journal of Multicultural Affairs

This study investigated public school teachers’ awareness of family engagement as a linguistic and cultural resource for multilingual students. Multilinguals are typically described as individuals who can communicate in more than one language, with English not being their native language, and their linguistic choices are influenced by societal norms and systems (Šifrar Kalan et al., 2024; Wei, 2008). Preparing pre-service teachers to enhance opportunities for multilingual students remains a critical need in teacher education programs, as they strive to move beyond monolingual ideologies in their teaching practices (Cárdenas Curiel et al., 2024; Kim & Choi, 2020; Williams & Ewing, 2019). …

An Overlooked Terrestrial Archive: Freshwater Cements And Hydroclimate Signals In Quaternary Glaciogenic Deposits, Owen F. Mccaffrey, Ian Z. Winkelstern, Tara A. Kneeshaw, Melinda C. Higley

University Faculty Publications and Creative Works

Quaternary glaciogenic deposits, which serve as vital groundwater aquifers, are often partially cemented with carbonate minerals, but the timing of emplacement of these cements and their geochemical conditions of formation remain understudied. Here, we integrated petrography, δ¹⁸O, Mg/Ca, and clumped isotope (Δ₄₇) data from two calcitecemented outcrops in western Michigan (USA) to investigate the origin of glacial sediment cements. The two sites have contrasting topographic and textural settings reflecting distinct formation conditions. The elevated Wabasis Lake deposit records sequential phreatic-to-vadose cementation, while the Cherry Valley Sands site, very close to the modern water table, shows a …

(R2124) Impact Of Delay And Awareness On Hiv/Aids Epidemic Model, Debashis Biswas

Applications and Applied Mathematics: An International Journal (AAM)

A delayed HIV/AIDS epidemic model with awareness has been taken here. Essentially, it is mentioned that the disease spreads among the population only through contact (horizontal transmission). The equilibrium points of both the proposed models are investigated, and their stability is discussed. Both models have two types of equilibria, namely the disease-free and the disease positive. The basic reproductive number of both models has been calculated by using the next generation matrix technique. In this paper, the main motivation is to find a way to decrease the disease transmission. Also discussed the impact of delay and awareness on the HIV/AIDS …

(R2167) Global Stability Of Seirs Model With Single Dose Vaccination In Varying Population, Govind Jha, Prabhat Mandal, Sarita Jha

Applications and Applied Mathematics: An International Journal (AAM)

Understanding the evolution of infectious diseases within a dynamic population is essential for formulating effective public health strategies. This work introduces an enhanced SEIRS epidemic model that incorporates demographic variation and a single-dose vaccination strategy, supporting that immunity can be reduced over time. The model reflects diseases in which individuals may return to the susceptible state after recovery. Extending prior reduced three-dimensional models, this study develops a complete four-dimensional SEIRS framework, thereby increasing the model’s applicability to real-world scenarios. The inclusion of the full system presents greater analytical challenges. To overcome this, we extend the second additive compound matrix and …

Dimensional Welfare Beyond Pain: Extending The Precautionary Principle In Birch’S “The Edge Of Sentience”, Willa M. Lane, Nicola S. Clayton

Animal Sentience

Birch's (2024) The Edge of Sentience identifies sentience candidates primarily through the pain-focused LSE Criteria. Yet, as Birch himself notes in Proposal 17, sentience is not pain. We argue that statutory welfare protections must therefore reach beyond pain, and that the right tool for doing so is Birch et al.’s (2020) dimensionality framework, which characterises conscious experience across five domains. Used together, the LSE Criteria establish that welfare is at stake, while the dimensionality framework maps what is at stake beyond pain to provide a taxon-specific profile of where captivity impoverishes experience. We apply this approach to invertebrate welfare and …

I report some rarely observed, infrequently reported, or hitherto unrecorded ecological interactions from the neotropics. These anecdotal observations were made opportunistically during nature tours or tropical biology classes in Belize, Panama, Costa Rica, and Trinidad & Tobago, between 2014 and 2024.

Sperm Morphology In The Eastern Narrow-Mouthed Frog, Gastrophryne Carolinensis (Anura: Microhylidae), S. E. Trauth

Journal of the Arkansas Academy of Science

Studies by Scheltinga et al. (2002) and Scheltinga and Jamieson (2003) provide the most comprehensive analysis and only review of sperm morphology in Narrow-Mouthed Frogs (family Microhylidae). Of the 490+ species known to occur in this anuran family (Vitt and Caldwell 2014), only 3 are distributed in the United States (Powell et al. 2016), and 2 of these occur in Arkansas (Trauth et al. 2004). Surprisingly, sperm studies on only 12 microhylid species have been conducted (Scheltinga and Jamieson 2003), and no sperm studies are available on any North American species.

Investigating Quinclorac Binding To Human Serum Albumin Using Spectroscopy And Molecular Docking, Le Nguyen, L. Hicks, L. Jodoin, S. Carby, D. S. Sanford, D. Benavides, A. Mishra, R. Yadav

Journal of the Arkansas Academy of Science

Human serum albumin (HSA) is the most abundant plasma protein and serves as a major transporter and reservoir for a wide range of endogenous ligands, including fatty acids, heme, bilirubin, prostaglandins, and metal ions, as well as numerous exogenous compounds, such as pharmaceuticals. HSA is a 66 kDa monomeric, multidomain protein containing two principal ligand-binding sites, Sudlow sites I and II. Sudlow site I contains Trp214, the sole tryptophan residue in HSA, whose intrinsic fluorescence provides a sensitive probe for studying ligand–protein interactions.

In this study, the interaction between HSA and the persistent organochlorine herbicide quinclorac (QNC) was investigated using …

Status Of The Gray Fox In Arkansas, D. B. Sasse

Journal of the Arkansas Academy of Science

The putative subspecies of gray fox (Urocyon cinereoargenteus ocythous) that is found in Arkansas has been proposed for federal protection under the Endangered Species Act, primarily due to potential population declines elsewhere in their range. In order to evaluate the need for such protection I evaluated the status of the gray fox in Arkansas utilizing data collected by the Arkansas Game and Fish Commission. Based on purchases of pelts by Arkansas-licensed fur dealers, opinions of Arkansas trappers about gray fox population trends, and hunter observation surveys, the gray fox appears to be widely distributed, abundant, and populations may …

History And Distribution Of The Dark Ibises (Glossy Ibis Plegadis Falcinellus And White-Faced Ibis P. Chihi) In Arkansas, R. Tumlison, P. D. Rodriguez

Journal of the Arkansas Academy of Science

The Glossy Ibis (Plegadis falcinellus) and White-faced Ibis (P. chihi) sometimes are reported simply as Dark Ibises due to difficulty in identifying them when mature characters are not clearly visible. We evaluated reports verified on citizen science websites to examine the origins and distributions of these migratory species in Arkansas. The Glossy Ibis was first documented in Arkansas in 1956, has been reported in 21 of our 75 counties, and is found more commonly in eastern Arkansas. The White-faced Ibis was first reported in Arkansas in 1971, has been reported in 41 of our 75 counties, …

History And Distribution Of Great-Tailed Grackles (Quiscalus Mexicanus) In Arkansas, R. Tumlison, V. Andersen

Journal of the Arkansas Academy of Science

Great-tailed Grackles (Quiscalus mexicanus) were reported first in southwestern Arkansas in 1969, were nesting there in 1977, and established a resident population by 1980. Nesting was reported in far northwestern Arkansas in 1986. Presently, the species is known from 44 of Arkansas’s 75 counties, those mostly in the western and central counties. Most individuals appear to be migratory, with most reports occurring in April and May. However, breeding and now resident populations have been reported in the southwestern, northwestern, and central counties, particularly in urban areas. Birds are very commonly reported to forage at fast-food establishments and truck …

Binucleation And Seasonal Cycle Of Sertoli Cells In The Western Lesser Siren, Siren Nettingi (Caudata: Sirenidae), S. E. Trauth

Journal of the Arkansas Academy of Science

I examined binucleation and the seasonal cycle of Sertoli cells in the Western Siren (Siren nettingi) using light microscopy and transmission electron microscopy. My primary objective in this study was to report, for the first time, the presence of double nuclei in Sertoli cells in a salamander. This study also represents the sixth contribution in a series of investigations that highlight the novel nature of all aspects of spermatogenesis in this unique salamander. My findings add to a growing list of extraordinary morphological and reproductive features that distinguish this salamander from all other vertebrates.

Distal Urogenital Anatomy And Epithelial Morphology In The Male Eastern Narrow-Mouthed Frog, Gastrophryne Carolinensis (Anura: Microhylidae), S. E. Trauth

Journal of the Arkansas Academy of Science

I investigated the microanatomy of the distal urogenital system in male Eastern Narrow-Mouthed Frogs (Gastrophryne carolinensis) from a small sample (n = 5) collected in central Arkansas in April, May, and July (2021) and May 2022. Specifically, my primary goals were to elucidate the histology of the following: (1) the paired Wolffian (urogenital) ducts caudally from the kidneys to their merging with the urodeum of the cloaca, (2) the structure of seminal vesicles, and (3) the epithelial morphologies among the distal urogenital tract, the posterior alimentary canal, and the cloaca.

Testing The Accuracy Of A Bear-Tracking Satellite Transmitter Collar Under Natural Conditions, K. A. Watson, K. Phipps, C. Drexler, C. R. Middaugh, M. Means, M. Hooks

Journal of the Arkansas Academy of Science

The Arkansas Game and Fish Commission tracks American black bears (Ursus americanus) using Global Positioning System (GPS) satellite telemetry collars in southeastern Arkansas to assess habitat use and behaviors. Companies test the accuracy of their devices, but researchers have found that natural environments, such as the forested habitat of black bears, can cause an increase in spatial error rates. We therefore tested 1 GPS collar in realistic conditions to help refine data interpretation. We placed the collar at 20 random locations in Columbia County, AR, stratifying habitat type based on data collected from black bears. We determined the …

Distribution And Impact Of Cogongrass (Imperata Cylindrica) In Northern Mississippi, Carl R. Pulver V, Ryan E. Burke, Elizabeth Esser, Evan Moore, Ashley Schulz

Endeavors: Mississippi State Undergraduate Research Journal

Cogongrass (Imperata cylindrica) is a non-native, rhizomatous grass that has invaded the southeastern United States. It forms dense mats that outcompete native plants, alters decomposition and microbial assemblages, and has highly flammable litter that alters fire behavior, affecting native plant communities. Though surveys for cogongrass have been conducted in southern Mississippi, the degree of cogongrass infestations in northern Mississippi has remained unclear and concerning. This study aimed to update cogongrass location data for the state and identify problem areas to guide state invasive plant management efforts. To provide a starting point, previously documented cogongrass locations were synthesized from natural history …

Endeavors: Mississippi State Undergraduate Research Journal

Bovine respiratory disease (BRD) is a multifactorial disease complex that causes significant economic loss in the cattle industry. Bovine respiratory syncytial virus (BRSV), one of the primary viruses included in BRD, primarily targets the lower respiratory tract and causes a wide variety of subclinical and clinical signs. Current diagnosis techniques require off-site laboratory testing, creating delays that allow BRSV to spread through herds and highlighting the need for rapid diagnostic methods. The objective of the study was to evaluate near-infrared spectroscopy as a diagnostic tool for BRSV detection across varying infection severities. Twenty-two Holstein bull calves were reared in research …
