Facilitating Culture Change To Boost Adoption And Creation Of Open Educational Resources At The University Of North Dakota, Stephanie Walker

Librarian Publications

In 2015, the University of North Dakota (UND) had no institutional program to promote adoption, creation, or utilization of Open Educational Resources (OERs). Few faculty were using, creating, reviewing, or in any way supporting OERs. To our knowledge, just three faculty members had written two open textbooks, and they received no institutional support. The culture of OERs and Open Access was not well known or understood across campus, and no institutions in the North Dakota University System (NDUS, a coalition of 11 public postsecondary institutions in North Dakota) had undertaken widespread promotion or adoption of OERs.

Within two years, however, …

Measuring Public Utilization Perception Potential Of Unmanned Aircraft Systems, Julius Keller, Daniel Kwasi Adjekum, Bortiorkor Nii Tsui Alabi, Brian Kozak

Aviation Faculty Publications

The integration of Unmanned Aircraft Systems (UAS) into the National Air Space (NAS) in recent times has been met by mixed public responses. The paper establishes four constructs each of which encapsulates multiple backgrounds and concerns of the stakeholders: functional knowledge, utilization trust, operational integration support, and safety risk-benefits. The paper hypothesizes that these constructs can serve as underlying components for a research instrument namely, the Public Utilization Perception Potential (PUPP) which can be used to assess the opinions of the public on UAS integration into NAS. Responses from the public on items in a beta-tested survey instrument were analyzed …

Towards Domain-Specific Modeling Methodology For Avionic Safety-Critical Systems, Emanuel S. Grant

Computer Science Faculty Publications

The use of domain-specific modeling languages and associated methodologies, provide support in application domain where the safe and reliable operations of the systems are of paramount importance to the users and organizations, and wherein the domains are well understood and documented. One such area of domain-specific modeling application is in the field of avionic systems. For software systems to be used onboard aircrafts they must be certified, and as such certification protocols have been established for developing these safety-critical systems. These established protocols are usually represented as textual documents and inherently are difficult to apply directly in software development environments. …

Computer Science Faculty Publications

Using automated processes to detect wildlife in uncontrolled outdoor imagery in the field of wildlife ecology is a challenging task. This is especially true in imagery provided by an Unmanned Aerial System (UAS), where the relative size of wildlife is small and visually similar to its background. This work presents an automated feedback loop which can be used to train convolutional neural networks with extremely unbalanced class sizes, which alleviates some of these challenges. This work utilizes UAS imagery collected by the Wildlife@Home project, which has employed citizen scientists and trained experts to go through collected UAS imagery and classify …

Uat Ads-B Data Anomalies And The Effect Of Flight Parameters On Dropout Occurrences, Asma Tabassum, William Semke

Mechanical Engineering Faculty Publications

An analysis of the performance of automatic dependent surveillance-broadcast (ADS-B) data received from the Grand Forks, North Dakota International Airport was carried out in this study. The purpose was to understand the vulnerabilities of the universal access transceiver (UAT) ADS-B system and recognize the effects on present and future air traffic control (ATC) operation. The Federal Aviation Administration (FAA) mandated all the general aviation aircraft to be equipped with ADS-B. The aircraft flying within United States and below the transition altitude (18,000 feet) are more likely to install a UAT ADS-B. At present, unmanned aircraft systems (UAS) and autonomous air …

The Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) campaign conducted in the southeast United States (SEUS) during the summer of 2013 provided a singular opportunity to study local aerosol chemistry and investigate aerosol radiative properties and PM2.5 relationships, focusing on the complexities involved in simplifying the relationship into a linear regression. We utilize three Southeastern Aerosol Research and Characterization network sites and one Environmental Protection Agency Chemical Speciation Network station that afforded simultaneous Aerosol Robotic Network (AERONET) aerosol optical depth (AOD) and aerosol mass, chemistry, and light scattering monitoring. Prediction of AERONET AOD …

Korean–English Bilingual Sibling Interactions And Socialization, Hyonsuk Cho

Teaching & Learning Faculty Publications

This paper examines how a pair of Korean–American siblings interact and socialize and how their interactions change over time as the younger sibling starts to go to an English-speaking preschool. A 7-year-old Korean–English bilingual girl and her 3-year-old sister were observed in their home over 23 visits within a year. Their discourse data, including 33 h of audio-recordings, were analyzed from the Language Socialization perspective. The older sibling’s authority derived from the age-based Korean family hierarchy inevitably played a role in creating shared benefits in the bilingual sibling relationship. After the younger sibling began to speak English, there were noticeable …

The Dark Energy Survey (DES) is a five-year optical imaging campaign with the goal of understanding the origin of cosmic acceleration. DES performs a ~5000 deg2 survey of the southern sky in five optical bands (g, r, i, z, Y) to a depth of ~24th magnitude. Contemporaneously, DES performs a deep, time-domain survey in four optical bands (g, r, i, z) over ~27 deg2. DES exposures are processed nightly with an evolving data reduction pipeline and evaluated for image quality to determine if they need to be retaken. Difference imaging and transient source detection are also …

Does Inequality Erode Cooperation In The Classroom? Evidence From Pisa 2015, Paul E. Sum, Gabriel Bădescu

Political Science & Public Administration Faculty Publications

We consider the relationship between SES equality and cooperation among high school students. We find that inequality decreases the acquisition of cooperation skills, a key ingredient to sustained democracy. Generalized trust and political equality counteract this effect independently. Further, trust and political equality moderate the influence of inequality, reaffirming the importance of education to democratic citizenship.

U-Band Measurement Of Star Formation In Cluster Galaxies, Wayne Barkhouse, Gihan Gamage, Sandanuwa Kalawila, Madina Sultanova, Dean Smith, Elijah Mathews, Haylee Archer

Physics Faculty Publications

We propose to obtain deep U-band observations of 14 low-redshift (z ≤ 0.06) galaxy clusters using the WIYN 0.9m+HDI telescope/detector to complete our survey to probe star formation of galaxies in high-density environments. These observations, combined with previously obtained data of 11 clusters observed using the same telescope+detector, will give us a statistically significant sample for the Ph.D. dissertation of co-I Gihan Gamage. Clusters are selected from 57 clusters in which we have obtained deep B- and R-band data using the KPNO 0.9m+MOSA. U-band data will allow us to explore relative changes in the luminosity function for the U- and …

Mapping Star Formation From The Core To The Outskirts Of Galaxy Clusters, Wayne Barkhouse, Gihan Gamage, Sandanuwa Kalawila, Madina Sultanova, Dean Smith, Elijah Mathews, Haylee Archer

Physics Faculty Publications

We propose for time to complete our u- and r-band imaging program of 30 low-redshift (z ≤ 0.03) galaxy clusters using the CTIO Blanco 4m+DECam telescope/detector combination. These data will allow us to probe star formation from the cluster core to the infall region, and complete the acquisition of observations for the Ph.D. dissertation of Gihan Gamage (University of North Dakota). The deep u- and r-band data will allow us to explore relative changes in the luminosity function, dwarf-to-giant ratio, blue fraction, and galaxy morphological type as a function of cluster-centric radius for a statistically significant sample of 30 clusters. …

How Readability Factors Are Differentially Associated With Performance For Students Of Different Backgrounds When Solving Mathematics Word Problems, Candace Walkington, Virginia Clinton, Pooja Shivraj

Educational Foundations and Research Faculty Publications

The link between reading and mathematics achievement is well known, and an important question is whether readability factors in mathematics problems are differentially impacting student groups. Using 20 years of data from the National Assessment of Educational Progress and the Trends in International Mathematics and Science Study, we examine how readability factors – such as length, word difficulty, and pronouns – interact with student background characteristics – such as race/ethnicity, mathematics achievement, and socioeconomic status. Textual features that make problems more difficult to process appear to differentially negatively impact struggling students, while features that make language easier to process appear …

Cognitive Fusion And Post-Trauma Functioning In Veterans: Examining The Mediating Roles Of Emotion Dysregulation, Daniel W. Cox, Thomas C. Motl, A. Myfanwy Bakker, Rachael A. Lunt

Education, Health & Behavior Studies Faculty Publications

When cognitively fused, people have difficulty accepting and clearly perceiving their internal experiences. Following trauma, emotional non-acceptance and emotional non-clarity have been associated with post-trauma functioning. The aim of the present study was to integrate theory and research on cognitive fusion and posttrauma functioning to evaluate a theory-based model in which emotion dysregulation—specifically, emotional non-acceptance and emotional non-clarity—mediated the association between cognitive fusion and post-trauma functioning in a veteran sample. Participants were 149 veterans with a history of military-related trauma. Veterans completed measures of cognitive fusion, emotion dysregulation, posttraumatic stress disorder (PTSD) symptoms, and life satisfaction. Overall, emotion dysregulation and …

Tangos Before Sunrise, Sunset And Midnight: A Conversational Journey With Jesse And Celine, Randy Rasmussen

Librarian Publications

Stripping the story of a romantic relationship down to its essentials, then fiercely delving into the details and potential variations of those essentials, director Richard Linklater and his collaborators created a unique trilogy of films spanning eighteen years in both real and fictional time. In Before Sunrise (1995), Before Sunset (2004) and Before Midnight (2013), two appealing yet flawed characters meet by chance on a train headed for Vienna, risk extending their acquaintance during a one-night tour of the city, then spend the next two decades either brooding about or deeply engaged with each other.

The biodiversity and high productivity of coastal terrestrial and aquatic habitats are the foundation for important benefits to human societies around the world. These globally distributed habitats need frequent and broad systematic assessments, but field surveys only cover a small fraction of these areas. Satellite-based sensors can repeatedly record the visible and near-infrared reflectance spectra that contain the absorption, scattering, and fluorescence signatures of functional phytoplankton groups, colored dissolved matter, and particulate matter near the surface ocean, and of biologically structured habitats (floating and emergent vegetation, benthic habitats like coral, seagrass, and algae). These measures can be incorporated into Essential …
