Forensic Analysis of Ink on Documents Using Direct Analyte-Probed Nanoextraction Coupled Techniques

Description: Analzying questioned documents in a nondestructive nature has been an issue for the forensic science community. Using nondestructive techniques such as video spectral comparator does not give reliable information due to the variations in gray or color levels that are distinguished differently by analysts. Destructive techniques such as chromatography give dependable, qualitative and quantitative, information but involves altering the evidentiary value of these questioned documents. The paradox … more

Mock Juror Effects of Blame and Conviction in Rape Cases: Do Attitudes, Beliefs, and Contact with Homosexuals Matter?

Description: The current case involves a female rape victim. Research has shown the level of victim blaming can be elevated if the victim is a lesbian woman compared to a heterosexual woman. Mock jurors’ responses to personality trait questionnaires (e.g., Belief in a Just World, Attitudes Toward Women, Attitudes Toward Lesbians) and amount of contact they have with homosexual people were employed as predictors of how they would decide victim blaming and perpetrator guilt. Personality trait findings were no… more

"Goodness and Mercy"

Description: The stories in this collection represent an increasingly transcultural world by exploring the intersection of cultures and identities in border spaces, particularly the Mexican-American border. Characters, regardless of ethnicity, experience the effects of migration and deportation in schools, hometowns, relationships, and elsewhere. The collection as a whole focuses on the issues and themes found in Mexican-American literature, such as loss, separation, and the search for identity.

Continuous Combinatorics of a Lattice Graph in the Cantor Space

Description: We present a novel theorem of Borel Combinatorics that sheds light on the types of continuous functions that can be defined on the Cantor space. We specifically consider the part X=F(2ᴳ) from the Cantor space, where the group G is the additive group of integer pairs ℤ². That is, X is the set of aperiodic {0,1} labelings of the two-dimensional infinite lattice graph. We give X the Bernoulli shift action, and this action induces a graph on X in which each connected component is again a two-dimen… more

Ours is the Kingdom of Heaven: Racial Construction of Early American Christian Identities

Description: This project interrogates how religious performance, either authentic or contrived, aids in the quest for freedom for oppressed peoples; how the rhetoric of the Enlightenment era pervades literatures delivered or written by Native Americans and African Americans; and how religious modes, such as evoking scripture, performing sacrifices, or relying upon providence, assist oppressed populations in their roles as early American authors and speakers. Even though the African American and Native Amer… more

Community-Based Logistics and Supply Chain Management: Developing, Testing and Validating Conceptual Models

Description: The field of Logistics and Supply Chain Management (LSCM) suggests that transactions, collaboration, and value are important in the supply and delivery of products and services to meet the need of impoverished end-consumers. In many cases, the application of LSCM is paramount in most strategic decision-making efforts. Therefore, this research explores the applications of LSCM processes and activities within the community-based context. The methodology used to address the research questions cons… more

The Influence of Urban Green Spaces on Declining Bumble Bees (Hymenoptera: Apidae)

Description: Bumble bees (Bombus spp.) are adept pollinators of countless cultivated and wild flowering plants, but many species have experienced declines in recent decades. Though urban sprawl has been implicated as a driving force of such losses, urban green spaces hold the potential to serve as habitat islands for bumble bees. As human populations continue to grow and metropolitan areas become larger, the survival of many bumble bee species will hinge on the identification and implementation of appropria… more
