First U-Pb Zircon Ages For Late Miocene Ashfall Konservat-Lagerstatte And Grove Lake Ashes From Eastern Great Plains, Usa, Jon J. Smith, Elijah Turner, Andreas Moller, Robert M. Joeckel, Rick E. Otto

Department of Earth and Atmospheric Sciences: Faculty Publications

This paper documents the first U-Pb zircon ages for Ashfall Fossil Beds (Nebraska, USA), a terrestrial Konservat-Lagerstatte mass-death assemblage that is arguably the most diverse of its type and age. The Ashfall tephra was correlated with ignimbrites from the Bruneau-Jarbidge volcanic field (12.7–10.5 Ma) in southwest Idaho based on geochemical analysis. The methods and geochemical data supporting the original age assessment of the ash bed, however, were never published, and there has been a persistent misconception that dateable heavy minerals (e.g., zircon) are absent. Notwithstanding, we recovered abundant zircons from Ashfall Fossil Beds, and from an ash bed ~6 km …

Genome-Scale Microrna Target Prediction Through Clustering With Dirichlet Process Mixture Model, Zeynep M. Hakguder, Jiang Shu, Chunxiao Liao, Kaiyue Pan, Juan Cui

School of Computing: Faculty Publications

Background: MicroRNA regulation is fundamentally responsible for fine-tuning the whole gene network in human and has been implicated in most physiological and pathological conditions. Studying regulatory impact of microRNA on various cellular and disease processes has resulted in numerous computational tools that investigate microRNA-mRNA interactions through the prediction of static binding site highly dependent on sequence pairing. However, what hindered the practical use of such target prediction is the interplay between competing and cooperative microRNA binding that complicates the whole regulatory process exceptionally.

Results: We developed a new method for improved microRNA target prediction based on Dirichlet Process …

Modeling And Testing A Family Of Surgical Robots: An Experience Report, Niloofar Mansoor, Jonathan A. Saddler, Bruno Silva, Hamid Bagheri, Myra B. Cohen, Shane Farritor

School of Computing: Faculty Publications

Safety-critical applications often use dependability cases to validate that specified properties are invariant, or to demonstrate a counter example showing how that property might be violated. However, most dependability cases are written with a single product in mind. At the same time, software product lines (families of related software products) have been studied with the goal of modeling variability and commonality, and building family based techniques for both analysis and testing. However, there has been little work on building an end to end dependability case for a software product line (where a property is modeled, a counter example is found …

Relational Uncertainty Management In Adult Children Of Divorce, Sylvia L. Mikucki-Enyart, Sarah R. Petitte, Sarah E. Wilder

Department of Communication Studies: Faculty Publications

Utilizing uncertainty management theory (UMT) and a multiple goals theory of personal relationships (MGPR) the present study examined how adult children of divorce (ACOD) manage relational uncertainty following parental divorce. In-depth, semistructured interviews with 25 adult children who had experienced parental divorce when they were 18 years of age or older revealed two broad types of information acquisition strategies: deliberate (i.e., information-seeking and information-avoiding) and incidental (i.e., incidental information acquisition). Deliberate information acquisition strategies were animated by several goals, including reducing and maintaining uncertainty, avoiding feeling caught, and protection. Alongside goals, various constraints (e.g., target efficacy, coping efficacy) played a …

Discourses Of Forgiveness And Resilience In Stepchild–Stepparent Relationships, Vincent R. Waldron, Dawn O. Braithwaite, Bailey M. Oliver, Dayna N. Kloeber, Jaclyn S. Marsh

Department of Communication Studies: Faculty Publications

Challenges and conflicts experienced by stepfamilies are well documented, but researchers are increasingly focused on communication processes that facilitate resilience in these relationships. In other contexts, communicating forgiveness has been linked to relational healing after transgressions or adversity. In the current study, the researchers sought to understand how stepchildren talk about the role of forgiveness in the development of positive adult stepchild–stepparent relationships. Data were drawn from interviews with adult stepchildren who have a positive relationship with a stepparent. Following an interpretive analysis, the researchers identified five themes representing the ways forgiveness was conceptualized and enacted in these positive stepchild–stepparent …
