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. …

Development And Validation Of The Value-Expectancy Stem Assessment Scale For Students In Higher Education, Joseph Appianing, Richard Van Eck

Teaching, Leadership & Professional Practice Faculty Publications

Background: Science, technology, engineering, and math (STEM) jobs are expected to make up a significant portion of the U.S. workforce. Unfortunately, the trend in retaining students in STEM majors has been going down. If higher education institutions are going to retain more students in STEM majors, it will be important to understand who leaves STEM fields and why. More than 32% of women college students who declare a STEM major are likely to switch to non-STEM majors before they graduate, whereas only 25% of their male counterparts do so, and women may be as much as 1.5 times more likely …

Comparison Of Autonomic Control Of Blood Pressure During Standing And Artificial Gravity Induced Via Short-Arm Human Centrifuge, Ajay K. Verma, Da Xu, Michelle Bruner, Amanmeet Garg, Nandu Goswami, Andrew P. Blaber, Kouhyar Tavakolian

Electrical Engineering Faculty Publications

Autonomic control of blood pressure is essential toward maintenance of cerebral perfusion during standing, failure of which could lead to fainting. Long-term exposure to microgravity deteriorates autonomic control of blood pressure. Consequently, astronauts experience orthostatic intolerance on their return to gravitational environment. Ground-based studies suggest sporadic training in artificial hypergravity can mitigate spaceflight deconditioning. In this regard, short-arm human centrifuge (SAHC), capable of creating artificial hypergravity of different g-loads, provides an auspicious training tool. Here, we compare autonomic control of blood pressure during centrifugation creating 1-g and 2-g at feet with standing in natural gravity. Continuous blood pressure was acquired …

Rambol, Krisztina Szoke, Jan E. Brinchmann, Arno C. Gutleb, Elisa Moschini, Alena Kubatova, Klara Kukowski, Eric Le Ferrec, Dominique Lagadic-Gossmann, Per E. Schwarze, Marit Lag, Magne Refsnes, Johan Ovrevik, Jorn A. Holme

Chemistry Faculty Publications

Background: Exposure to traffic-derived particulate matter (PM), such as diesel exhaust particles (DEP), is a leading environmental cause of cardiovascular disease (CVD), and may contribute to endothelial dysfunction and development of atherosclerosis. It is still debated how DEP and other inhaled PM can contribute to CVD. However, organic chemicals (OC) adhered to the particle surface, are considered central to many of the biological effects. In the present study, we have explored the ability of OC from DEP to reach the endothelium and trigger proinflammatory reactions, a central step on the path to atherosclerosis.

Results: Exposure-relevant concentrations of DEP (0.12 μg/cm2 …

Brinchmann, Eric Le Ferrec, Normand Podechard, Dominique Lagadic-Gossmann, Kenji F. Shoji, Aubin Penna, Klara Kukowski, Jorn A. Holme, Johan Ovrevik

Chemistry Faculty Publications

Exposure to diesel exhaust particles (DEPs) affects endothelial function and may contribute to the development of atherosclerosis and vasomotor dysfunction. As intracellular calcium concentration [Ca²⁺]_i is considered important in myoendothelial signalling, we explored the effects of extractable organic matter from DEPs (DEP-EOM) on [Ca²⁺]_i and membrane microstructure in endothelial cells. DEP-EOM of increasing polarity was obtained by pressurized sequential extraction of DEPs with n-hexane (n-Hex-EOM), dichloromethane (DCM-EOM), methanol, and water. Chemical analysis revealed that the majority of organic matter was extracted by the n-Hex- and DCM-EOM, with polycyclic aromatic hydrocarbons primarily occurring in n-Hex-EOM. …
