Effects Of A Historical Story On Student Understanding Of Nos, Peng Dai Apr 2018

Effects Of A Historical Story On Student Understanding Of Nos, Peng Dai

Research and Creative Activities Poster Day

Science educators have identified that Nature of Science (NOS) is essential to improve students’ science literacy. Numerous empirical studies suggest that incorporating the history of science (HOS) into class by means of an explicit reflective approach is one way to promote students’ NOS conceptions. In view of these findings, we developed a unit using an interrupted story technique to depict the discovery of the structure of DNA featuring Rosalind Franklin’s neglected role to help students learn both science content and NOS. Our study design compares an experimental group (story used) with a control group (no story used). The SUSSI (a …

Human Behavior Modeling For Residential Energy Consumption, Mesfer Alrizq

Research and Creative Activities Poster Day

Electric utility companies are interested in load profile (electricity consumption) data for expansion planning. Conventional methods of collecting the load profile data, such as surveys and metering, are tedious and time consuming activities. Cumbersome data collection processes also pose barriers. We present an innovative behavior model for generating electricity consumption load profiles. The model, based on fuzzy logic and activity graphs, requires minimum consumer data and can be easily updated to adapt to changes in technology. We demonstrate the accuracy of our model against real world data.

Characterization Of A Neuroprotective Retinal Synapse After Inducing Glaucoma In Long Evans Rats, Cynthia A. Cooley-Themm

Research and Creative Activities Poster Day

Glaucoma is a group of degenerative retinal diseases characterized by progressive loss of retinal ganglion cells (RGCs) and their axons leading to irreversible loss of vision. Neuroprotection has been defined as any intervention that prevents optic nerve damage or RGC death. The neurotransmitter, acetycholine (ACh), has been linked to neuroprotection against excitotoxic cell death and neurodegenerative diseases of the central nervous system (CNS). Results from our lab have demonstrated that ACh provides neuroprotection against glutamate-induced excitotoxicity in isolated pig and rat RGCs in vitro. Additional studies using an in vivo rat model of glaucoma have shown that intravitreal injections or …

Enhance A Deep Neural Network Model For Twitter Sentiment Analysis By Incorporating A User-Level Information, Ahmed Sulaiman M Alharbi

Research and Creative Activities Poster Day

Most existing sentiment classification methods for social media focus on document-level classification. They utilize local text information and ignore the crucial characteristic information of users. These methods usually suffer from high model complexity and only exhibit word-level preference.

Therefore, motivated by the successful utilization of deep neural networks in computer vision, speech recognition and natural language processing and their ability of learning in multi-prospective ways, a neural network based sentiment analysis model is proposed to incorporate user-level information into sentiment classification.

By user-level information we mean information extracted or inferred from the user that helps the proposed model to engage …

Why Do Women Delay In Seeking Prenatal Care? A Discrete-Time Survival Analysis, Ama Agyeiwaa Abrokwah

Research and Creative Activities Poster Day

Prenatal care during early stages of pregnancy can result in early detection of some pregnancy related complications which can help reduce both maternal and infant mortality (Conway et al., 2006). The cost of service has been identified as an important determinant of the utilization of prenatal care in most developing countries. This paper evaluates how Ghana’s social health insurance program affects the timing of prenatal care utilization using survival analysis techniques. This paper hypothesizes that having insurance will result in early utilization of prenatal care.

Black Women As Scapegoats: The Mass Incarceration Of Black Men And The Social Stigma Of The Welfare Queen, Keiondra J. Grace, Olivia M. Mclaughlin Apr 2017

Black Women As Scapegoats: The Mass Incarceration Of Black Men And The Social Stigma Of The Welfare Queen, Keiondra J. Grace, Olivia M. Mclaughlin

Research and Creative Activities Poster Day

In popular and academic discourse, African American women are regarded as the source of all social ills within the inner-city. This has become increasingly true in the era of mass incarceration, resultant of the War on Drugs. While Black men are portrayed as violent criminals, Black women are portrayed as the drug addicted, welfare queens they left behind. This trend can be explained, in part, by the actions of politicians and researchers who appear to remain ignorant to the importance of recognizing social structures such as gender, race, and class. We argue that Black single mothers, some of the most …

The Quantum Dancing Of Hot Atomic Nuclei: A New Theoretical Approach, Herlik Wibowo

Research and Creative Activities Poster Day

We study the nuclear excitation spectra in the two energy domains: the low energy region (below 10 MeV) and giant resonance (GR) region (10-30 MeV). In the low energy region, the experimentally discovered upbend of the radiative dipole strength function is very important as it has an impact on the rapid neutron capture cross sections, which are used, in particular, for the r-process nucleosynthesis studies.

Thermal continuum quasiparticle random-phase approximation (TCQRPA) is one of the models which attempts to explain this phenomenon. The deficiency of TCQRPA is the absence of quasiparticle vibration coupling (QVC) mechanism, which is already included in …

Selective Incarceration And Extraction Of Oxoanion Contaminants From Aqueous Media By Self-Assembled Nanojars, Basil Ahmed Apr 2016

Selective Incarceration And Extraction Of Oxoanion Contaminants From Aqueous Media By Self-Assembled Nanojars, Basil Ahmed

Research and Creative Activities Poster Day

Selective binding and extraction of anions by artificial receptors is one of the most far‐reaching areas of supramolecular chemistry, with implications in chemical, biological and environmental sciences. The extraction of kosmotropic anions from aqueous media is challenging, due to their large hydration energies (affinity for water). We have recently shown that a class of toroidal copper(II)‐hydroxide/pyrazolate complexes (nanojars), with the formula [Cu(OH)(pz)]n (n = 27−36), totally incarcerate kosmotropic anions with an unprecedented strength. Lined by H‐bond donors on the inside and hydrophobic on the outside, these ~2 nm sized assemblies selectively extract kosmotropic anions from mixtures with chaotropic anions …
