Comparison Of Bond Strength Between A Conventional Resin Adhesive And A Resin-Modified Glass Ionomer Adhesive: An In Vitro And In Vivo Study., Andrew Waldron Summers Jan 2002

Comparison Of Bond Strength Between A Conventional Resin Adhesive And A Resin-Modified Glass Ionomer Adhesive: An In Vitro And In Vivo Study., Andrew Waldron Summers

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this study was todetermine the in vivo survival rate and in vitro bond strength of orthodontic brackets bonded with a resin-modified glass ionomer adhesive (RMGI) (Fuji Ortho LC, GC America) and a conventional resin adhesive (Light Bond, Reliance Orthodontic Inc.). Two Fuji Ortho LC groups and two Light Bond groups were tested in vitro. Debonding force was determined with an Instron testing machine, and data was analyzed using ANOVA at p< 0.05. A significant difference was found among all four test groups with Light Bond having the greatest debonding force. Fuji Ortho LC had a higher mean ARI value. For the in vivo study data was analyzed using the Kaplan-Meier product-limit estimates. No significant difference was found between the two adhesives survival rate or ARI. These results suggest that the clinical bond strength for RMGI is adequate to withstand orthodontic forces.

Environmental Justice Through Pollution Prevention: Development Of A Quantitative Method To Assess Community Vulnerability And Air Emission Hazard For Optimal Impact., John Lewis Boettner Iii

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study develops a quantitative and objective method of analyzing community vulnerability combined with potential exposure to emission hazards. This extends earlier work concerning Environmental Justice Through Pollution Prevention (EJP2) initiatives for optimal selection of facilities for resource allocation for pollution prevention initiatives. A 1992 EPA report indicated that minority and low-income communities are exposed to higher levels of pollution in their neighborhoods than that of the general population. Environmental Justice is a grassroots derived term for addressing these disproportionate shares of negative environmental impacts, which are placed upon people of minority or low socio-economic status. The method developed identifies …

Cross-Border Workers' Compensation Coverage And Nafta: Analysis Of Coverage In American And Canadian Jurisdictions., Patricia Cathleen Kimpan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Workers’ compensation is a social insurance program with different attributes in the United States, Canada and Mexico. Workers’ compensation programs are largely privately funded. In all North American jurisdictions, workers’ compensation benefits are paid for by employers, through insurance premiums. More dangerous occupations have higher premium rates than do safer occupations and industries. The North American Free Trade Agreement (NAFTA) makes more likely the possibility that workers from one jurisdiction, made ill or injured by their employment, will seek help in a transborder jurisdiction. A survey of North American regulators was conducted. Trucking and transportation are important industries in workers’ …

The Potential Of Soil Survey Data In A Quantitative Evaluation Of Surficial Geology Mapping In Northern Maine., Rosalia Evans Jan 2002

The Potential Of Soil Survey Data In A Quantitative Evaluation Of Surficial Geology Mapping In Northern Maine., Rosalia Evans

Graduate Theses, Dissertations, and Problem Reports (ETD)

The soil-surficial geology relationships along the St. John River in northern Maine suggest that surficial geology is the most important factor controlling soil-profile genesis. Therefore, the information available on soil survey maps is predictive of the surficial geology of those areas. The agreement between a derivative surficial geology map created from soil survey data and maps created by conventional geological mapping differs little from the agreement between conventional geological maps. Soil survey maps can be used to make general assumptions about surficial geology patterns in northern New England and adjacent Canadian Provinces. Sitespecific applications using soil survey maps to determine …

The Relationship Between Family Communication Patterns And Locus Of Control., Andrea Marie Nardello Jan 2002

The Relationship Between Family Communication Patterns And Locus Of Control., Andrea Marie Nardello

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study used the newly developed Interpersonal-Goal Locus of Control scale (IGLOC) and the Revised Family Communication Patterns (RFCP) scale to investigate the relationship between people’s family communication growing up with their sense of locus of control later in life. It was hypothesized that family communication patterns would be related to the subscales of the IGLOC. College undergraduates (N=215) were given a survey which measured their locus of control and family communication patterns. Results of a Pearson Correlation show conversation-orientation to be positively related to internal, structural, other-owned, and negatively related to normative and phenomenal locus of control. Conformity-orientation was …

The Reluctant Delegate: Alexander Campbell And The Statehood Movement In Western Virginia., Jill Adana Rogers Jan 2002

The Reluctant Delegate: Alexander Campbell And The Statehood Movement In Western Virginia., Jill Adana Rogers

Graduate Theses, Dissertations, and Problem Reports (ETD)

When Alexander Campbell, a young Scots-Irish minister, immigrated to the United States in 1809, he encountered a new nation that was pulsating with religious revival, hungry for more territory, and already divided by the “peculiar institution” of slavery. Within twenty years, Campbell established himself as a well-known religious reformer, educator, and landholder in Virginia’s Northern Panhandle. Although Campbell otherwise believed in separation of church and state, he agreed to participate as a western political delegate to the 1829-1830 Virginia Constitutional Convention. Campbell’s able representation of western sectional interests astounded other more politically experienced delegates. Disheartened by eastern Virginia’s suppression of …

A Model For Building A Better Academic Web Site: A Quantitative Analysis Of Foreign Language Departments On The World Wide Web., Margarita (Maria) M. Toro

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis defines what an effective academic web site is, and examines the utilization of web sites by the Land Grant colleges’ foreign language departments. A system with the parameters of evaluation was created from studies that observed web users’ perceptions of web sites. Four main factors were analyzed: informativeness, interactivity, entertainment, design and usability. The results showed that departments of foreign language are not projecting a positive image throughout their web sites. Moreover, the web masters of the foreign language departmental sites are not considering entertainment and interactivity features as fundamental elements in the development of academic web sites.

Differential Reinforcement Of Fixed-Interval Interresponse Times: Effects On Choice., Tammy Renee Wade

Graduate Theses, Dissertations, and Problem Reports (ETD)

Eight rats were exposed to a concurrent-chains procedure. Half of the rats chose between a fixed-interval schedule that required low rates of responding in the paced terminal link and a simple fixed-interval schedule in the unpaced terminal link. The other half chose between a fixed-interval schedule that required high rates of responding and a simple fixed-interval schedule. Interresponse-time criteria were based on the percentiles of a baseline distribution of interresponse times obtained for each rat. The criteria increased in stringency across conditions. Consistent changes in response rates as the result of the interresponse-time criteria were not obtained. Therefore, preference between …
