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.

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 …

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 …

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 …
