Policy Analysis Of The Illinois Nurse Practice Act (Aprn Title Section 65/65-50), Sara Kim Nov 2021

Policy Analysis Of The Illinois Nurse Practice Act (Aprn Title Section 65/65-50), Sara Kim

Doctor of Nursing Practice Projects

Background

Physician groups claim allowing nurses to use the title "doctor" confuses patients. Nurses assert that the title is common to many disciplines, and nurses should be trusted like other professionals to identify their specialty to patients. Currently, qualified nurses in Illinois using the title "doctor" in clinical areas must introduce themselves to each patient in the following way: "Hi, I'm Dr. Smith, the nurse practitioner taking care of you today. I do not have a degree in medicine, and I am not a physician or medical doctor” (225 ILCS § 65/65-50).

Purpose

This project aimed to evaluate Illinois Nurse …


A Note On Cannibalism And Synchrony In Seabird Egg-Laying Behavior, Yosia Nurhan Apr 2021

A Note On Cannibalism And Synchrony In Seabird Egg-Laying Behavior, Yosia Nurhan

Honors Theses

During years of high sea surface temperature, food resources for glaucous-winged gulls (Larus glaucescens) are scarce. In response, male gulls cannibalize the eggs of neighbors. When this occurs, female gulls in dense areas of the colony adopt a tactic of egg-laying synchrony, in which they lay eggs synchronously on an every- other-day schedule. Field observations show that the first laid egg of each clutch is the most likely to be cannibalized. In this paper, we analyzed a discrete-time model of egg-laying behavior that tracks egg order in the nest. Using Jury Conditions, we found that the equilibrium destabilizes into a …

Comparisons Of Silver Nanoparticle Synthesis Methods By Microwave And Non-Microwave Using Hydrogen Gas As A Reducing Agent, Sofia Erech Hanapin

Honors Theses

Synthesis and characterization of silver nanoparticles are of current interest. This research project describes a simple and rapid synthesis of silver nanoparticles upon reduction of Silver (I) oxide (Ag2O) by molecular hydrogen (H2) at elevated temperature (70 – 100 °C) and a pressure of > 1 atmosphere by heating the aqueous mixture using a common kitchen microwave. This reaction generates naked silver colloids that contain no foreign stabilizers other than metal particles in aqueous media. Its application of an antibacterial effect was monitored by using biological cultures using the Kirby-Bauer Test.


Finding Optimal Opa-Iblc Derivatized Amino Acid Analysis Parameters With Three-Dimensional Fluorometric Scans For Hplc Method Validation, Aaron Jacobs Apr 2021

Finding Optimal Opa-Iblc Derivatized Amino Acid Analysis Parameters With Three-Dimensional Fluorometric Scans For Hplc Method Validation, Aaron Jacobs

Honors Theses

Three-dimensional fluorometric scans of OPA-IBLC derivatized glutamic acid and histidine solutions revealed that decreasing concentration maintained maximum λem but produced different maximum λex. In pH 0.4 M sodium borate buffer (pH 10.4), 50 μM derivatized amino acid solutions had maxima around 350- to 450-nm λex-λem where 12.5 μM solutions had maxima around 230- to 450-nm λex- λem. In the lower concentration, the λex peak at 230 nm was about 80% higher than 350 nm. Thus, collecting spectra with 230 nm λex would provide better LOD and LOQ. Results inform HPLC standard concentrations since differential quenching effects may produce non-linear calibration …


Computational Difficulty And Invariants Of The Snake Cube Puzzle, Adrian Negrea Apr 2021

Computational Difficulty And Invariants Of The Snake Cube Puzzle, Adrian Negrea

Honors Theses

The snake cube is a popular puzzle that has been analyzed for its computational difficulty and shown to be NP-complete. Conceiving of the puzzle as a Hamiltonian path in an n x n x n graph, we offer a novel mathematical analysis by considering invariants of the puzzle. This allows us to determine necessary conditions for a particular snake cube to be solvable and eliminate a large class of possible puzzles as unsolvable. In particular, we establish upper and lower bounds on the possible number of straight components in solvable snake cube puzzles.

The enamel of teeth may be corroded after death, especially if the teeth pass through the digestive tract of a predator with low gastric pH. This study characterized enamel corrosion of fossil squirrel teeth from two species (Otospermophilus rexroadensis and Ictidomys meadensis) obtained from the Fox Canyon locality of Kansas. Using microscopic imaging, I categorized teeth based on corrosion level. Overall, 45% of specimens exhibited heavy to extreme corrosion. There were no significant differences in the distribution of corrosion categories between both upper and lower teeth of either species (O. rexroadensis: X2 (3, N = 140) = .562, p= .905; …


Producing Music Using Negative Harmony, Jeremy Ahn Apr 2021

Producing Music Using Negative Harmony, Jeremy Ahn

Honors Theses

This project uses Negative Harmony as a basis and reference point for producing original songs in the style of instrumental jazz and funk. Negative harmony is a loose term that describes a technique of reharmonization made popular by musician Jacob Collier. While negative harmony is best understood as a reharmonization technique, writing new songs and chord progressions that strive to replace common chord progressions with their negative harmony counterparts can also be an effective way to demonstrate negative harmony. Music can be made with unconventional sounding but harmonically viable chords that challenge both the musician and the listener to grow …

Socioeconomic Status And Ethnicity As Predictors Of Childhood Career Aspirations, Sydney Saint-Jean

Honors Theses

Beginning at an early age, children discuss what they want to be when they grow up. This is known as their career aspirations. There are multiple factors that influence the career aspirations of children. Some of which includes familial income level, grade level and ethnicity. Although studies suggest that there is a relationship between income level and career aspirations, there is a gap in the literature when examining the relationships between socioeconomic status, ethnicity, grade level, and their effects on the career aspirations of children. This study explores this multi-level relationship on what a child wants to be when they …


Comparison Of Enamel Microstructure Of Ictidomys Tridecemlineatus Formed During Hibernation Versus The Active Season, Amanda Cho Apr 2021

Comparison Of Enamel Microstructure Of Ictidomys Tridecemlineatus Formed During Hibernation Versus The Active Season, Amanda Cho

Honors Theses

Ground squirrel incisors grow continuously, preserving a record of their most recent weeks of life. Previous research demonstrated that an abnormality in the surface of incisor enamel and dentin of thirteen-lined ground squirrels (Ictidomys tridecemlineatus) corresponded with hibernation. Using scanning electron microscopy, we compared internal microstructure of incisor enamel deposited during and outside of hibernation to determine if surface disruptions corresponded to differences in internal microstructure. For one specimen, hibernation enamel displayed irregularities in microstructure that were not present in non-hibernation enamel, but this difference was not observed in other specimens. Given these inconclusive results, further research is warranted.

Perceived Effectiveness Of A Mentoring Program For Training Adventist Chinese Evangelists, Terry Man-Yuen Tsui Jan 2021

Perceived Effectiveness Of A Mentoring Program For Training Adventist Chinese Evangelists, Terry Man-Yuen Tsui

Dissertations

Problem

The fact that evangelism in the Unorganized Territories of the Chinese Union Mission was done mainly as personal evangelism and that public evangelism was limited to a one-day seed sowing meeting had led to a serious need for equipping pastors in effective public evangelism methods. It required a model of public evangelism, which is adaptable to the local Chinese culture, and a mentoring program that accompanies evangelists, who were still developing their skills in public evangelism.

Method

This study used a parallel mixed methods design to measure the perceived effectiveness of selected methods in the mentoring program. This design …

An Analysis And Comparison Of The Missional Doctrine Hermeneutics Of Kevin J. Vanhoozer And Veli-Matti KäRkkäInen, With Emphasis On Their Notions Of God, Eschatology, And Mission, Elmer Arrais Guzman

Dissertations

This dissertation analyzes Veli-Matti Kärkkäinen’s and Kevin J. Vanhoozer’s theological method, in order to understand its structural elements, and thereby to facilitate comprehension of their missional doctrinal hermeneutics, and the ramifications of those hermeneutics for the construction and development of Christian theology. Missional doctrinal hermeneutical models conceive the missional dimension of doctrine in various ways. Some privilege the maintenance of theological identity cohering with the foundational sources of theological authority. Others privilege theological constructions that assimilate the context and the missional situational framework of understanding. This dissertation strives to examine the diverging missional hermeneutics of Kärkkäinen and Vanhoozer, the foundational …


An Exploratory Study Of Mathematics Anxiety In Caribbean Preservice Teachers, Franka Atwell-Chin Hong Jan 2021

An Exploratory Study Of Mathematics Anxiety In Caribbean Preservice Teachers, Franka Atwell-Chin Hong

Dissertations

The Problem

Correlational studies suggest that gender, attitudes to mathematics, mathematics performance, the number of college mathematics courses taken, and mathematics teacher efficacy beliefs may be related to mathematics anxiety among preservice teachers (Boyd et al., 2014; Gresham, 2018; Jaggernauth & Jameson-Charles, 2015). Exploratory studies of mathematics anxiety and teacher self-efficacy among elementary teachers exist in Trinidad and Tobago (Jaggernauth 2012; Jaggernauth & Jameson-Charles, 2015). However, the differences in samples, and weakness in methodology, may make it challenging to generalize the results to the preservice teacher population. In addition, no studies have found which variable or combination of variables is …

Pottery Horizons Of The Jalul Ceramic Assemblage In The Iron Age Iia-C From Square G4 In Its Historical And Geographical Context, Michael Christian Orellana Mendez

Dissertations

Problem

Several scholars have debated the traditional and low chronology of the Iron Age in Southern Levant using pottery as one of their main pieces of evidence. Both approaches disagree in regards to the dates assigned to the early Iron Age II pottery. To achieve a better understanding of the problem, the still rudimentary knowledge of Iron Age II pottery in Transjordan needs to be improved. Since 1992, Tall Jalul—the largest tell site in the central Jordan plateau—has been due for a comprehensive study of its ceramic assemblages. The site produced Iron Age IIA-C pottery in stratified layers, and it …

Coping Skills, Emotional Intelligence, Attachment, And Resilience On Post-Traumatic Stress Disorder In Private Sector Emergency Medical Technicians, Brenda-Joyce Gonzales Orozco Markert-Green

Dissertations

Problem

Private sector Emergency Medical Technicians (EMTs) are first responders who respond to traumatic incident scenes along with firefighters and police officers. However, news agencies and the public do not acknowledge private sector EMTs with the same vigor or accolade as public sector EMTs, nor are the risks to life, health, and mental well-being recognized among this population. Thus, the research literature has been sparse regarding how private sector EMTs experience PTSD, and what unique risk factors and needs may be present.

Purpose Statement

The purpose of this study was to examine the relationship between PTSD symptoms and coping skills, …


When God Gets Angry: Towards A Theology Of Divine Wrath, Lukas Daeubler Jan 2021

When God Gets Angry: Towards A Theology Of Divine Wrath, Lukas Daeubler

Master's Theses

Topic

One of the most significant concerns regarding the character and love of God is God’s wrath, especially in the Old Testament. For many, it is impossible to believe in a God who punishes and kills rather than a God who shows compassion and love for all people. They neglect either the violent parts of the Bible, since they seem to contradict the image of a loving God displayed in the Gospels. This of course directly questions the integrity of God and His word. As a response, some theologians have published papers on this topic, but many Christians and denominations …


The Removal Of Sin In Second Temple Jewish Literature, Odiaka Walker Jan 2021

The Removal Of Sin In Second Temple Jewish Literature, Odiaka Walker

Master's Theses

Problem

This thesis explored the Second Temple literary background of the concept that Jesus appeared at the end of the ages to take away sin, in Heb 9:26. As such, the research question which guided the paper was: what did Old Testament and Intertestamental writers believe about the removal of sin at the end of the ages? The answer to this question infers other questions: who would remove sin? From where would sin be removed? How was sin defined? How would sin be removed? When would sin be removed (are there time specifications involved)?

Method

The terms ἀφαιρέω, ἀφίημι, ἀπαλείφω, …
