Relationship Between Movement And Student Behaviors, Amy L. Ackerman

Master's Theses & Capstone Projects

The purpose of this action research project was to determine the relationship between movement opportunities and student behaviors, specifically off-task behaviors. Participants were twenty-five, four and five-year-olds in a public, inclusive, half-day preschool setting. Data was collected through observation during a ten-minute end of the day large group meeting for six weeks. Various movement opportunities were provided ranging from no breaks, ten-minute in-classroom brain breaks, and fifteen-minute gross-motor recess breaks. Any reminders given to attend to the large group meeting were recorded and later analyzed to suggest that movement opportunities affect student behaviors in a positive manner.

Play In Early Childhood, Keri Griswold

Master's Theses & Capstone Projects

This literature review looks at play in early childhood education and why play is important for early learners. The review looks at the history of play and the benefits that play has on brain development, as well as defining play. Adults play an important role in play, as does the early childhood learning environment. Early learners develop their critical thinking skills and their social and emotional skills through play. The curriculum that is offered to early learners should revolve around play but should ensure that they are being provided the opportunity to learn about the outdoors, math, reading, and all …

Sem/Edx Analysis Of Bronze Disease, Brian Pauley, Nicole Bishop

Fall 2018 - Chemical Analysis Class Projects

Bronze disease is a type of self-progressing corrosion of bronze. This degradation is thought to be caused by humidity but proliferated through the formation of chlorine containing compounds that further react with the air. The origination of the bronze disease in this artifact is thought to have arisen from the tanning process used in the surrounding leather. It is highly probable that potassium chloride was used in the tanning process, providing the initial chlorides that cause bronze disease. The damage that this corrosion can cause can destroy priceless artifacts. An understanding of the bronze disease structure and chemical composition is …

The Characterization Of Leather Wwii Artifacts Using Gc/Ms And Raman Spectroscopy, Brice Houser

Fall 2018 - Chemical Analysis Class Projects

Many museums face the challenge of protecting artifacts from deterioration. This process is often hampered by the history of the artifact, which can introduce factors that start or speed up the process of deterioration. An example of this is the method used during WW II to preserve leather. Mink oil or other fatty substances are used to help preserve and soften leather. A major component of mink oil is palmitic acid.

1 This fatty acid may have reacted with the brass in the same way that the oils from the hand react with coins to make that distinctive metallic smell, …

Raman Spectroscopy Of Bronze Disease On Wwii Artifacts, Andrea M. Reutzel

Fall 2018 - Chemical Analysis Class Projects

Patina is a film that forms on bronze or similar metals over a long period of time due to an oxidation reaction. If cuprous chloride in copper alloys are present, it reacts with water to create hydrochloric acid. Hydrochloric acid in the presence of metals will cause corrosions of the bronze and over time it will completely eat away at the metal. This reaction, known as Bronze Disease, is different than patina. Patina can act as a coat and preserver for metals. The University of Northern Iowa’s Museum is experiencing Bronze Disease on artifacts in the WWII collection. The Bronze …

An Empirical Analysis Of The Sacrifice Ratio In Nigeria, Ada Tony Odu, Onyebuchi David Anih

Bullion

This study empirically investigates the existence of a sacrifice ratio for Nigeria and to measure it, if one exists over the disinflation episodes. The study adopted the Ball (1994) methodology and the Hodrick-Prescott (HP) filter technique to examine the cost of disinflation to Nigeria. Six (6) disinflation episodes were identified over the 2000Q1 – 2018Q2 period and the results obtained indicated varying amounts of output losses over the different episodes under study. The findings suggested that a 1% disinflation resulted in output losses ranging from - 0.02% to 0.44% for the Nigerian economy. Both methods, however, suggested that the latest …

Amplifying The Prediction Of Team Performance Through Swarm Intelligence And Machine Learning, Erick Michael Harris

Master's Theses

Modern companies are increasingly relying on groups of individuals to reach organizational goals and objectives, however many organizations struggle to cultivate optimal teams that can maximize performance. Fortunately, existing research has established that group personality composition (GPC), across five dimensions of personality, is a promising indicator of team effectiveness. Additionally, recent advances in technology have enabled groups of humans to form real-time, closed-loop systems that are modeled after natural swarms, like flocks of birds and colonies of bees. These Artificial Swarm Intelligences (ASI) have been shown to amplify performance in a wide range of tasks, from forecasting financial markets to …

Improving Ultra-Wideband Localization By Detecting Radio Misclassification, Cory A. Mayer

Master's Theses

The Global Positioning System (GPS) and other satellite-based positioning systems are often a key component in applications requiring localization. However, accurate positioning in areas with poor GPS coverage, such as inside buildings and in dense cities, is in increasing demand for many modern applications. Fortunately, recent developments in ultra-wideband (UWB) radio technology have enabled precise positioning in places where it was not previously possible by utilizing multipath-resistant wide band pulses.

Although ultra-wideband signals are less prone to multipath interference, it is still a bottleneck as increasingly ambitious projects continue to demand higher precision. Some UWB radios include on-board detection of …

Token-Based Blockchain Financing And Governance: A Transaction Cost Economics Approach, Lesław Pietrewicz

Studia i Materiały Wydział Zarządzania Uniwersytet Warszawski

The paper presents a conceptual analysis of token-based blockchain financing and governance. Its aim is to explore governance attributes of tokens – a new financial instrument issued by blockchain startups – with a view to understanding deployment of tokens by blockchains and their design. Transaction cost economics (TCE) has been chosen as a theoretical perspective for the analysis. The paper extends the scope of TCE theory by applying it to the blockchain context, and to the study of the role and nature of tokens in particular. It is argued that blockchains aggregate and coordinate the contributions of a distributed network …

Mutual Relations Of Macroeconomic Balances – Conclusions From International Comparisons, Jerzy Żyżyński

Studia i Materiały Wydział Zarządzania Uniwersytet Warszawski

We are still witnessing many misconceptions stemming from misunderstanding of macroeconomic conditions upon which macroeconomic stability relies. The economy is a complex mechanism consisting of great many communicating vessels between which the income and expenditure of a variety of entities are flowing. According to the most synthetic macroeconomic approach, in the case of an open economy, such flows make an arrangement of three macroeconomic balances which are interrelated by the following equation, discussed hundreds of times in macroeconomic literature: (G – T) = (S – I) + (Z – X). The very essence of the conditions of the macroeconomic stability …

Who Benefits From Accountability-Driven School Closure? Evidence From New York City, Robert Bifulco, David Schwegman

Center for Policy Research

We estimate the effects of accountability-driven school closure in New York City on students who attended middle schools that were closed at the time of closure and students who would have likely attended a closed middle school had it remained open. We find that students who would have entered the closed school, had it not closed, attended schools that perform better on standardized exams and have higher value-added measures than did the closed schools. While we find that closure did not have any measurable effect on the average student in this group, we do find that high-performing students in this …

On The Efficiency Of Stock Markets: A Case Of Selected Opec Member Countries, Ebenezer A. Olubiyi, Peter O. Olopade

CBN Journal of Applied Statistics (JAS)

The study investigates the stock market efficiency of selected OPEC member countries within the context of random walk hypothesis and volatility approaches using monthly data on stock market indices from January, 2005 to April, 2016. Parametric (variance ratio: homoskedastic and heteroskedastic martingale), nonparametric (the Wright ranks and scores) tests and ARCHtype estimation are performed. Results of both parametric and nonparametric tests indicate that only Qatar’s stock market is weak-form efficient. The volatility results suggest that monthly stock returns of OPEC countries are volatile, with Qatar being most volatile and shocks to volatility of stock returns are asymmetric. The implications of …

School of Computing: Dissertations, Theses, and Student Research

The main appeal of the Cloud is in its cost effective and flexible access to computing power. Apache Storm is a data processing framework used to process streaming data. In our work we explore the possibility of offering Apache Storm as a software service. Further, we take advantage of the cgroups feature in Storm to divide the computing power of worker machine into smaller units to be offered to users. We predict that the compute bounds placed on the cgroups could be used to approximate the state of the workflow. We discuss the limitations of the current schedulers in facilitating …

Reducing The Tail Latency Of A Distributed Nosql Database, Jun Wu

School of Computing: Dissertations, Theses, and Student Research

The request latency is an important performance metric of a distributed database, such as the popular Apache Cassandra, because of its direct impact on the user experience. Specifically, the latency of a read or write request is defined as the total time interval from the instant when a user makes the request to the instant when the user receives the request, and it involves not only the actual read or write time at a specific database node, but also various types of latency introduced by the distributed mechanism of the database. Most of the current work focuses only on reducing …
