Historical Chaos Among Tetrabothriideans (Eucestoda) Of Odontocetes (Artiodactyla)—Revising Generic Taxonomy And Species Diversity For Cestodes Among Oceanic Dolphins, Eric P. Hoberg, Kaylen Marie Soudachanh, Robert L. Rausch

MANTER: Journal of Parasite Biodiversity

Explorations over the past 150 years that have defined the diversity and structure of the tetrabothriidean cestode fauna among Odontocete cetaceans (Artiodactyla) are summarized and reviewed. Persistent errors in interpretation of comparative morphological characters, inconsistent taxonomic decisions, and an understanding of generic-level and species diversity are addressed. We outline a revision of the Tetrabothriidea, which now encompasses 8 genera. Prosthecocotyle is resurrected from synonymy with Tetrabothrius, and Cetaceobothridius n. gen is proposed. A clear basis is outlined for differentiation of generic and species diversity among Cetaceobothridius, Priapocephalus, Prosthecocotyle, Strobilocephalus, Tetrabothrius, and Trigonocotyle that constitute the tetrabothriidean fauna of odontocetes; species …

Methodological Variations In Environmental Justice Screening Tools And Their Impact On Disadvantaged Community Designations, Thomas Robbins, Qingran Li, Stephen Bird

Faculty Publications

Government agencies in the United States have developed environmental justice screening tools (EJSTs) and designations to promote equitable distribution of benefits from environmental policies to disadvantaged communities (DACs). However, the methodological choices embedded in these tools, including the selection, weighting, and aggregation of environmental justice indicators, vary across EJSTs, and their implications for DAC designation outcomes are poorly understood. Here we systematically compare four EJSTs at the federal and state levels and show that these tools produce substantial variation in the DAC census tracts, with some tools emphasizing socioeconomic burdens while others prioritize environmental risks. Using quantitative regression models, we …

The Social Construction Of Firearm Meaning In 2022 Hollywood Films: A Qualitative Content Analysis, Anthony L. Paduano

The Correlation Of Information-Seeking Traits With Perceptions Of Artificial Intelligence Output To Ill-Defined Problems, Joel Bouchard

Doctoral Dissertations and Projects

Artificial intelligence (AI) has emerged as a new class of technological tool whose innovation exists in its ability to engage in reciprocal, socially fluent, undetermined response generation. How individuals come to trust such responses, especially as it regards classes of problems previously unavailable to programmed computational responses, is a question of importance. Prior research has addressed motivational dispositions towards epistemic decision-making, but work examining the relationship between these traits and perceptions of AI output in epistemically ambiguous circumstances is limited. The current study aimed to address this gap by exploring how trait curiosity and need for cognitive closure (NFCC) relate …

Tongues In 1 Corinthians 12–14: Their Role In Gospel Proclamation And Unity, Adam Rimmer

Doctoral Dissertations and Projects

The gifts of the Holy Spirit have been controversial throughout the ages. Many theologians, apologists, and church fathers have tried to clarify glossolalia. This dissertation is an exposition of 1 Corinthians 12–14 that argues that glossolalia is an actual human language that supports the gift of prophecy for proclaiming the gospel of Jesus Christ, but was being misused within the church at Corinth as ecstatic speech, which was not the valid biblical gift of glossolalia. It will demonstrate that this gift served as a divine means to proclaim the gospel of Jesus Christ to those who spoke different languages before …
