Mechanism Of Chromium Reduction Of Benzo[A]Pyrene Diolepoxide Mutagenesis In Human Fibroblasts, Cara Suzanne Kriss

Masters Theses

Environmental agents can cause an increase in cellular stress and damage DNA which can lead to diseases such as cancer. Chromium produces cellular stress by increasing the reactive oxygen species through a Fenton-like reaction, where chromium reacts with hydrogen peroxide to form hydroxyl radicals. Benzo[ a ]pyrene is an environmental carcinogen that is metabolized by cytochrome p450 enzymes into benzo[a]pyrene diolepoxide (BPDE). BPDE is highly reactive with DNA producing large DNA-adducts primarily on guanine nucleotides. The primary intracellular pathway by which mammalian cells remove damaged DNA caused by bulky mutagens is nucleotide excision repair. We have found that, in BPDE …

Masters Theses

The use of a body weight support hydraulic system can be beneficial for athletes with lower extremity injuries to help maintain cardiovascular fitness and provide athletes with the ability to advance lower extremity injuries to full weight bearing earlier than without a body weight support harness. However, body weight support harnesses can be a limiting factor due to rubbing or riding up when an injured athlete is attempting to maintain their current level of cardiovascular fitness. Discomfort is experienced with the use of many harnesses in the form of rubbing, tightness, and sliding up the torso. Two different body weight …

A Drug Free America? A Web Page Discourse Analysis, Darrin Kowitz

Masters Theses

Using the methods of Critical Discourse Analysis (CDA), this research will seek to identify the ways in which social power is exercised through the creation and manipulation of linguistic categories within the text of the web page for the Partnership for a Drug Free America (PDFA). A preliminary examination of the web page identified three general mechanisms of power at work for the PDFA, the use of authority, fear inducement, and identity manipulation. The use of these mechanisms will be analyzed to explain ideological hegemony as the adoption of cognitive categories by individuals from social-structural, or institutional, sources.

Athletic Amenorrhea: Prevalence And Awareness Among Female Athletes At Western Michigan University, Michele R. Chupurdia

Eating Ethnicity: Examining 18th Century French Colonial Identity Through Selective Consumption Of Animal Resources In The North American Interior, Rory J. Becker

Masters Theses

Cultural identities can be created and maintained through daily practice and food consum.ption is one such practice. People need food in order to survive, but the types of food they eat are largely determined by the interaction of culture and their environment. By approaching the topic of subsistence practices as being culturally constituted, the study of foodways provides an avenue to examine issues of cultural identity through selective consumption. Eating certain foods to the exclusion of others is one method for establishing social distance between peoples and is simultaneously a reflection of this relationship and the types of interactions that …

The Role Of Economic, Political, And Cultural Factors In Immigration Policy In France, The United Kingdom, And Germany, Sheri L. Rogers

Masters Theses

Immigration policy has been a crucial issue facing all Western European countries for decades; however, it has recently become an even greater concern. Much of the literature argues that shifts in immigration policy correspond with shifts in economic conditions or the power of far-right parties. Others argue that immigration policy is primarily a cultural issue, although very little research has been done to address the role of specific cultural factors in different countries.

This paper looks at the evolution of immigration policy in France, the United Kingdom, and Germany, and addresses the question of why immigration policies in each country …

Superimposition And Withdrawal Of Tangible Consequences As A Treatment For Automatically Reinforced Problem Behaviors, Tina M. Sidener

Masters Theses

Tangible superimposition and withdrawal is a reductive procedure in which a new stimulus is delivered following behavior already maintained by a different controlling stimulus. The new stimulus is then removed in an attempt to reduce behavior. The current investigation sought to extend previous research on this procedure by evaluating its efficacy and durability as a treatment for stereotypy in three children diagnosed with autism. First, automatic reinforcement functions for stereotypic behaviors were identified via functional analyses. Next, for two participants, tangible items were delivered contingent upon stereotypy and then subsequently withdrawn. When the superimposition procedure proved ineffective, environmental enrichment was …

Improving Functional Assessment With Computer-Based Data Collection And Analysis Software, Rebecca May

Masters Theses

Many students exhibit behavior problems in the classroom that can negatively affect academic performance and social/emotional functioning if not identified and appropriately accommodated (Sugai, Lewis-Palmer, and Hagan, 1998; Scott, DeSimone, Fowler, and Webb, 2000). In order to combat the increasing number of students with behavior problems, an efficient means of assessing and treating problem behavior is warranted (Nelson and Johnson, 1996). Traditional observation methods are limited in the number of behaviors recordable and elaborateness of data analysis (Sharpe and Koperwas, 2001), and do not lend themselves to direct treatment development (Nelson, Roberts, Bullis, Albers, and Ohland, n.d.). Computer-based data collection …
