Facilitating Pre-Service Teachers To Engage Emergent Bilinguals In Productive Struggle, Benjamin T. Dickey, Jim Ewing, Melissa Caruso, Emily D. Fulmer

Journal of Multicultural Affairs

This study utilized a multiple case study with qualitative research to examine how Pre-service teachers (PSTs) might engage Emergent Bilinguals (EBs) in productive struggle—grappling to solve problems (Warshauer, 2015). The researchers created a rubric based on Warshauer’s (2015) case study to record the types of questions PSTs asked as they tutored fourth grade EBs. Warshauer (2015) claimed PSTs should allow students more wait time and ask questions. She referred to such questions as affordance and probing guidance, which facilitates productive struggle. In order to discover more about the PSTs’ thinking, the researchers interviewed the PSTs before and after their first, …

An Examination Of The Death Penalty, Alexandra N. Kremer

The Downtown Review

The death penalty, or capital punishment, is the use of execution through hanging, beheading, drowning, gas chambers, lethal injection, and electrocution among others in response to a crime. This has spurred much debate on whether it should be used for reasons such as ethics, revenge, economics, effectiveness as a deterrent, and constitutionality. Capital punishment has roots that date back to the 18^th century B.C., but, as of 2016, has been abolished in law or practice by more than two thirds of the world’s countries and several states within the United States. Here, the arguments for and against the death …

Stability Of Delayed Virus Infection Model With A General Incidence Rate And Adaptive Immune Response, Zhimin Chen, Xiuxiang Liu, Zhongzhong Xie

Applications and Applied Mathematics: An International Journal (AAM)

We present the dynamical behaviors of a virus infection model with general infection rate, immune responses and two intracellular delays which describe the interactions of the HIV virus, target cells, CTL cells and antibodies within host. Three factors are incorporated in this model: (1) the intrinsic growth rate of uninfected cells, (2) a nonlinear incidence rate function considering both virus-tocell infection and cell-to-cell transmission, and (3) a nonlinear productivity and removal function. By the method of Lyapunov functionals and LaSalle’s invariance principle, we show that the global dynamics of the model is determined by the reproductive numbers for viral infection …

Parameter Estimation And Optimal Control Of The Dynamics Of Transmission Of Tuberculosis With Application To Cameroon, A. Temgoua, Y. Malong, J. Mbang, S. Bowong

Applications and Applied Mathematics: An International Journal (AAM)

This paper deals with the problem of parameter estimation and optimal control of a tuberculosis (TB) model with seasonal fluctuations. We first present a uncontrolled TB model with seasonal fluctuations. We present the theoretical analysis of the uncontrolled TB model without seasonal fluctuations. After, we propose a numerical study to estimate the unknown parameters of the TB model with seasonal fluctuations according to demographic and epidemiological data from Cameroon. Simulation results are in good accordance with the seasonal variation of the new active reported cases of TB in Cameroon. Using this TB model with seasonality, the tuberculosis control is formulated …

Parameter Sensitivity For In Vitro Anthrax Studies, Yareley Gonzalez, Maria Macias-Bedolla, Megan O. Powell

Spora: A Journal of Biomathematics

Studies done on interactions between spores and macrophages done in vitro show inconsistent results based on experimental protocol and inhibit meaningful extrapolation to in vivo. In this study, we perform a sensitivity analysis of a model representing in vitro studies of interactions between anthrax spores and macrophages to help address the effects of these inconsistencies. We perform both local and global analyses using Latin hypercube sampling and partial rank correlation coefficients. Our analysis indicates the amount of intracellular bacteria over time is most sensitive to the killing of intracellular bacteria by the macrophages and replication of the bacteria inside …

The Effect Of Two Different Harvesting Methods On The Yield Of 'Topbunch' And 'Hi-Crop' Collards (Brassica Oleracea (L)) When Grown In A Wiregrass Tunnel House, Veronica E. Walton, Raymon Shange, Melissa Johnson, Edward Sparks, Victor Khan, James E. Currington, Ramble Ankumah, Nathaniel Ellison, George X. Hunter Jr., Jeffery L. Moore

Professional Agricultural Workers Journal

A study was conducted to determine if 100% or 50% harvesting of collard leaves was a suitable recommendation for Tunnel House producers. The experiment was conducted as a split-split plot design with varieties as the main plots, harvesting 100% or 50% of leaves as the sub-plots, and days after transplanting as the subplots. All treatments were replicated three times, drip irrigated, and fertilized according to soil test recommendations. The results showed significant interactions between varieties and method of harvest, for leaf numbers and weight. Conversely, the varieties showed significant differences for yield but not leaf numbers. Both varieties showed significant …

The Evaluation Of Two Different Harvesting 'Topbunch' And 'Hi-Crop' Collards (Brassica Oleracea (L)) Leaves From Plants Grown In A Wiregrass Tunnel House, Edward Sparks, Raymon Shange, Jacquelyn Jackson, Victor Khan, James E. Currington, Ramble Ankumah, Nathaniel Ellison, George X. Hunter Jr., Jeffery L. Moore

Professional Agricultural Workers Journal

A study was conducted to determine if a 100% or 50% harvest intensity of ‘Topbunch’ collards leaves could be a recommended practice for Tunnel House producers. The experiment was conducted as a split-plot design with harvest dates as main plots, and harvesting intensity of 100% or 50% of leaves as sub-plots. All treatments were replicated three times, drip irrigated, and fertilized according to soil test recommendations. The results showed significant interactions between harvest methods and dates for number and weight of leaves harvested. There were also significant differences for the weight of leaves harvested and numbers. The leaf recovery rates …

Adam And Eve, Designed Diversity, And Allele Frequencies, John C. Sanford, Robert W. Carter, Wes Brewer, John Baumgardner, Bruce Potter, Jon Potter

Proceedings of the International Conference on Creationism

Theistic evolutionists present multiple genetic arguments against a literal Adam and Eve. One key argument asserts it would be impossible for a single human couple to give rise to the genetic diversity seen in the modern human population. This implicitly assumes Adam and Eve would have been created without internal genetic diversity. If this were true, all observed variations would have to arise recently via random mutations. This would require incredibly high mutation rates, logically leading to rapid extinction.

Yet, Adam and Eve could have been created massively heterozygous. We have argued for over a decade that they could have …

The Dinosauria: Baraminological And Multivariate Patterns, Neal A. Doran, Matthew Mclain, Natalie Young, Adam Sanderson

Proceedings of the International Conference on Creationism

The Dinosauria pose both interesting and challenging questions for creationist systematists. One question is whether new dinosaur discoveries are closing morphospatial gaps between dinosaurian groups, revealing continuous morphological fossil series, such as between coelurosaurians and avialans. Questions such as these underscore the importance of systematics for resolving correct group memberships, including tools for visualizing morphospatial relationships. Baraminic distance correlation (BDC), three-dimensional multidimensional scaling (MDS), and a new method to baraminic studies – principal component analysis (PCA) – were applied to 18 character matrices from 2004. The data included saurischian and ornithischian dinosaur groups including (1) “basal” Saurischia, (2) Ceratosauria (including …

Old And Recent Processes In A Warm And Humid Desert Hypogene Cave: ‘A’Rak Na‘Asane, Israel, Amos Frumkin, Shlomi Aharon, Uri Davidovich, Boaz Langford, Yoav Negev, Micka Ullman, Anton Vaks, Shemesh Ya‘Aran, Boaz Zissu

International Journal of Speleology

Recent environmental processes are studied in ʻA’rak Naʻasane Cave at the northern Judean Desert, Israel. The outer zone of the cave is heavily influenced by the outside environment through a large entrance, facilitating entry of air flow, fauna and humans, with minor cave-forming modifications. Conversely, the inner cave sustains humid and warm conditions, favoring modifications by condensation corrosion of convective air flow, associated with deposition of popcorn speleothems at the lower parts of dissolution pockets. The warm humid air of the inner cave may be associated with an underlying thermal water table. Active condensation corrosion is decreasing, possibly because of …

You Can Judge A Bearer By Its Bark: Dogs Use Sound To Size Up Conspecifics, Zachary Silver

CrissCross

A variety of mammalian species use vocalizations to perceive the size of conspecifics. This ability may be an evolutionary adaptation shared by many mammalian species allowing them to detect the presence of a threat when visual resources are scarce or unavailable. Specifically, some mammals demonstrate prolonged attention to manipulated calls that suggest a larger conspecific compared to those suggesting a smaller conspecific. In humans this behavioral effect depends on the observer’s size—perceptions of ‘big’ or ‘small’ may differ between individuals. We explored whether this generalizes to other species by manipulating formant dispersion of dogs’ own barks to create synthetic barks …

Identification Of Coliphages In The Aviary At Brookgreen Gardens And The Factors That Might Influence Coliphage Population Dynamics In This Cypress Swamp Environment, Olivia Shirley, Lisa Pieterse, Paul E. Richardson

Journal of the South Carolina Academy of Science

It has been understood that the presence of coliphages (bacteriophages specific for E. coli) in water is an indirect measurement of fecal contamination. Bacteriophages have been suggested to hold an important role in regulating the bacterial population. This pilot study analyzes the relationship between the presence of coliphages in the water in the aviary at Brookgreen Gardens and how environmental factors such as temperature, pH, and turbidity affect the presence of these viruses over the time period of three months (June 2017 through August 2017). Coliphages found in volary water sources were speculated to be deposited directly by birds that …

An Investigation Of The Order Of Applying An Emollient With A Topical Steroid In The Treatment Of Atopic Dermatitis, Andrea Conner, Ashlee Tietje

Journal of the South Carolina Academy of Science

In 2007, the prevalence of Atopic Dermatitis had increased two to three-fold within the last three decades and affected 15-20% of young children (Buys, 2007). Current treatment includes the use of both steroid and emollient creams. Current suggestions for the order of application are contradictory. This study aims to examine the role of the order of application of treatments for Atopic Dermatitis (AD). Hairless mice (SKH-1) were induced to a mild AD flare-up using 2,4-dinitrochlorobenzene (DNCB) and treated with either 1% hydrocortisone (Maximum Strength Cortizone 10 cream) alone, 1% hydrocortisone followed by Cetaphil (emollient), or Cetaphil followed by 1% hydrocortisone. …

Investigating The Lytic Staphylococcus Aureus Bacteriophage Reservoir Amongst A South Carolina University Population: Discovery, Characterization, And Identification Of A Potential Bacteriophage Treatment For Methicillin-Resistant Staphylococcus Aureus, Lisa Pieterse, Amy Powers, Derek Pride, Lisha Van Onselen, Giovanna E. Leone, Paul E. Richardson

Journal of the South Carolina Academy of Science

Bacteriophages are viruses that only infect bacterial cells and can be used to treat antibiotic resistant bacterial infections. This study focused on the isolation and characterization of bacteriophages lytic to Staphylococcus aureus at Coastal Carolina University (CCU) in Conway, South Carolina, as a means to isolate bacteriophages that can potentially be used to treat methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant S. aureus variant. From 2014 to 2018, collection of ear and nose samples from 225 randomly selected CCU volunteers was conducted. Filter sterilization, amplification, microbial tests, and PCR analyses were performed in order to identify and characterize bacteriophages. Coliphage populations …
