On The Double Chain Ladder For Reserve Estimation With Bootstrap Applications, Larissa Schoepf

Masters Theses

"To avoid insolvency, insurance companies must have enough reserves to fulfill their present and future commitment-refer to in this thesis as outstanding claims towards policyholders. This entails having an accurate and reliable estimate of funds necessary to cover those claims as they are presented. One of the major techniques used by practitioners and researchers is the single chain ladder method. However, though most popular and widely used, the method does not offer a good understanding of the distributional properties of the way claims evolve. In a series of recent papers, researchers have focused on two potential components of outstanding claims, …

Evaluation Of Ultra-High Performance Concrete (Uhpc) In Joints Of Bridge Girders, Saipavan Rallabhandhi

Masters Theses

"Joints are often considered as the weak link in a structure and often deterioration of the structure initiates from the joints. Joints transfer the stresses from super-structure to sub-structure and in this process are subjected to large transfer stresses. Not much attention is given to the design of joints as they are positioned in low moment regions and typically a 4 to 6 ksi (28 to 41 MPa) concrete is used to fill the joints. One of the solution to this problem is Ultra-high performance concrete (UHPC). In the recent past significant research has been done to use UHPC in …

Divergent Responses Of Cryptic Invasive Watermilfoil To Treatment With Auxinic Herbicides In A Large Michigan Lake, Syndell R. Parks

Masters Theses

Invasive plants are a major concern for environmental managers. Cryptic invasive taxa present additional challenges because of their potential to respond differently to management efforts. Invasive Eurasian watermilfoil (Myriophyllum spicatum) and hybrid watermilfoil (Myriophyllum spicatum x Myriophyllum sibiricum) cannot be reliably distinguished based on morphological characters and are therefore cryptic taxa. Laboratory studies show that on average, hybrid watermilfoil grows faster, branches more, and is less responsive to standard control measures developed for Eurasian watermilfoil. These laboratory results predict less effective control of hybrid watermilfoil in mixed populations treated uniformly with one of these control measures. However, to date there …

Adult Rainbow Trout Habitat Selection In The Henry’S Fork Of The Snake River, Idaho, Zachary Kuzniar

Masters Theses

Determining habitat selection for an organism across a geographic distribution is a primary challenge in modern behavioral ecology. Quantifying habitat use becomes increasingly difficult for species that exhibit complex life histories and complementary habitat requirements. Rainbow trout are an archetypal example due to their tendency to form local populations across a diversity of environments. The Henry’s Fork of the Snake River provides an opportunity to utilize microhabitat selection models to quantify stream features that may drive adult rainbow trout behavior at the local scale. In particular, within an 8.5 km, low gradient, groundwater-dominated reach that exhibits a general lack of …

Functional Movement Screen Score By Somatotype Category, Amanda Kelch

Masters Theses

Background: The Functional Movement Screen (FMS) is a tool used by fitness and health professionals to assess the quality of movement patterns in active populations. The literature has established descriptive values for FMS scores in various populations. However there has not yet been a study establishing the descriptive values of FMS score based on the somatotype categories. Establishing these descriptive values may provide a better understanding of how an individual's somatotype affects their ability to move. Purpose: The purpose of this study was to establish FMS scores for the four simplified somatotype categories (normal, endomorph, mesomorph, and ectomorph). Methods: Participants …

Harry Potter And The American Response: Persecution And Popularity Of The Boy Who Lived, Ashley N. Zirkle

Masters Theses

Some people, such as J.K. Rowling’s Harry Potter, eagerly embrace the opportunities that magic promises. Others, however, fear and despise magic, and so condemn anything that contains so much as a sprinkle of pixie dust, just as Harry’s aunt and uncle do. A look into the reception of the Harry Potter series, particularly in the United States, demonstrates how these two responses to magic occur, and why this series in particular created such strong reactions from both sides. With a long history of banning literature that contains magic, it is little surprise that many religious conservatives felt the need to …

Christian Chicken Vs. Mainstream Media: A Case Study Analysis Of Chick-Fil-A’S Stance On Traditional Marriage Using Situational Crisis Communication Theory, Christiannn Mcnew

Masters Theses

A crisis can strike an organization at any moment and it is the responsibility of the organization to be prepared with a plan of action. This thesis will explore crisis management, using Timothy Coombs’ crisis management strategies, of Chick-fil-A and then COO Dan Cathy to see if those two parties implemented crisis strategies in a way that benefited the organization following Cathy’s statements in support of the biblical definition of family. Since many interpreted these comments as anti-gay sentiments from Chick-fil-A itself, crisis struck the organization Cathy represented. This thesis will also look at the idea of social activism in …

Thus, this study aimed to examine both the psychophysiological and subjective responses to dissonance and the difference in these responses between those with high experience and those with low experience. Participating groups, categorized as high experience (HE) and low experience (LE) in terms of musical knowledge, listened to consonant and dissonant musical excerpts, and rated each excerpt on its pleasantness; their physiologic responses were measured to …

Implementing A Linear Quadratic Spacecraft Attitude Control System, Daniel Kolosa

Masters Theses

This thesis implements a linear quadratic attitude control system for a low-thrust spacecraft. The goal is to maintain spacecraft alignment with a time-varying thrust vector needed for trajectory change maneuvers. A linear quadratic attitude control approach is used to maintain spacecraft pointing throughout flight. This attitude control strategy uses the thrust-acceleration input obtained from a linear quadratic optimal trajectory control model that simulates the trajectory of a spacecraft in orbit maneuvers. This attitude model simulates a CubeSat, a small satellite that is equipped with a low-thrust propulsion and attitude control system. An orbit raising and a plane change scenario is …

Analyzing Repetitive Sequences With Structured Dynamic Bayesian Networks, Thomas. L. Lake

Masters Theses

Time series often feature structure that is known a priori and easily described using natural language terms such as repetitive, symmetric, seasonal, and self-similar. However, the typical conjugate priors used in Bayesian analysis do not capture such complex phenomena well. As a result of this mismatch, known structure is modeled poorly or completely ignored. Focusing on time series with repetitive structure, this thesis proposes to overcome this problem by reducing rather than in- creasing the capacity of a well know time series model, the Hidden Markov Model. Through a careful choice in the way model capacity is reduced the model …

The Taphonomic Factors On Human Remains Inside Chullpas: Marcajirca, Peru, Samantha Lauren Lininger

Petrological And Geochemical Evaluation Of The Sturgeon Falls Intrusive Body, Jonathan Michael Haynes

Masters Theses

The Sturgeon Falls Intrusive Body (SFIB) is a gabbroic intrusion located along the Michigan-Wisconsin border just south of the town of Norway, MI. The SFIB is bounded to the north by the Niagara Shear Zone and the Michigamme Formation (Schulz and Cannon, 2006) and to the south by an unnamed thrust fault zone and the Quinnesec Formation (Sims and Schulz, 1993). Field mapping has shown that the SFIB is composed almost entirely of metagabbro metamorphosed to greenschist facies, with isolated outcrops of clinopyroxenite, which are thought to be xenoliths.

The origin of the SFIB is controversial. Schulz and LeBerge (2003) …

Expression Of Insulin Responsive Genes In Insulin Resistant Conditions, And The Effect Of Selenium On Gene Expression, David L. Ruff

Masters Theses

Chronically high blood glucose levels lead to many problems, such as insulin resistance, the hallmark of Type II diabetes. Increased flux through the hexosamine biosynthesis pathway is one mechanism by which high glucose as well as glucosamine has been shown to induce insulin resistance. This study tests the effects of glucosamine induced insulin resistance on insulin regulation of the metabolic genes glucose-6-phosphate dehydrogenase (G6PDH) and fatty acid synthase (FAS) as well as insulin responsive proteins tribbles homolog (TRIB3) and sterol regulatory element binding protein (SERBP-1c) 1c.

Selenium, a micronutrient has been shown to be an effective insulin mimetic in Type …

“Struck With Her Tongue”: Speech, Gender, And Power In King Lear, Kate Downey Hickey

Masters Theses

My thesis addresses the supposed sexism in William Shakespeare’s King Lear through an examination of the power of speech in the play. Employing a variety of scholarship, I argue that Cordelia exerts power both through prudent speech and in her silence, adhering to Renaissance expectations for women but also defying the unreasonable behavior of her father. I explore how Cordelia’s values are recognized by and through other characters, especially Lear’s Fool. While Cordelia is often viewed as the opposite of her sisters Goneril and Regan, I provide a reading of the play that treats all three sisters as complex characters …

Depositional Facies And Sequence Stratigraphy Of Niagaran-Lower Salina Reef Complex Reservoirs Of The Guelph Formation, Michigan Basin, Matthew J. Rine

Masters Theses

Hydrocarbon reservoirs in the Niagara-Lower Salina Reef Complex in the Michigan Basin have been extensively studied since the early 1960’s. These reservoirs host an immense hydrocarbon resource, existing as closely-spaced, highly-compartmentalized reservoirs that have produced >500 million barrels of oil and 2.9 trillion cubic feet of natural gas. Previous studies depict these “pinnacle reefs” as tall, symmetrical towers with a random distribution of facies. This study utilizes abundant core data (32 cores, 20-acre spacing), thin-section petrography, and petrophysical wire-line logs to reconstruct the geometry, facies distributions, depositional history, and sequence stratigraphy of the Columbus III Reef Complex within the Southern …

“Men Of Good Timber”: An Archaeological Investigation Of Labor In Michigan’S Upper Peninsula, Aaron Howe

Masters Theses

This study approaches the material assemblage of Coalwood, a cordwood camp that operated from 1900-1912 in Michigan’s Upper Peninsula, with a dialectal method and a theory of internal relations in order to understand how daily life was produced and reproduced. Common sense notions often see home and work as separate entities that only relate to one another externally. My archaeological and historical research abstracts domestic labor as a set of social relations that are dialectically and internally connected to the processes of capital accumulation. My archaeological analysis concludes that both productive and reproductive labor was conducted within the home and …

Formulation And Evaluation Of Soy Polymer Based, Gravure Printed Resistive Inks For Applications In Printed Electronics, Bhushan Hiralal Patil

Masters Theses

Today, the majority of the commercially available conductive inks are formulated using expensive metallic particles, such as silver and gold. Most of the inks use volatile solvents in the formulation, which are hazardous to the environment as emission of VOCs is the major concern. In the case of water-based inks, usually petroleum-based acrylic polymers are used. Apart from being nonrenewable raw materials, acrylic polymers are carcinogenic in nature. Also, acrylic polymers are used in a variety of applications, such as the automotive, medical device, paint, and adhesive industries.
