Faculty, Staff and Student Publications

Poly(lactic acid) (PLA) is widely used in the field of medicine due to its biocompatibility, versatility, and cost-effectiveness. Three-dimensional (3D) printing or the systematic deposition of PLA in layers has enabled the fabrication of customized scaffolds for various biomedical and clinical applications. In tissue engineering and regenerative medicine, 3D-printed PLA has been mostly used to generate bone tissue scaffolds, typically in combination with different polymers and ceramics. PLA's versatility has also allowed the development of drug-eluting constructs for the controlled release of various agents, such as antibiotics, antivirals, anti-hypertensives, chemotherapeutics, hormones, and vitamins. Additionally, 3D-printed PLA has recently been used …

Automated Customer Assistance Is Not Customer Service, Chris Roberts Phd, Lisa Young Phd, Misty M. Johanson Phd, Mary Jo Dolasinski Phd

ICHRIE Research Reports

For development of the theory of service, the focus is on the constructs of service. The theory is expanded to encompass the various business models of service and the service encounter including but not limited to guest satisfaction, service quality, service and technology, service system design, and customer relationship management. Consideration is given to the aspects of the service transaction and what constitutes service, where a labor component of a firm’s product has been transferred to the customer. Lastly, self-service and automation are considered in the context of the user experience. A model of the theory of service is presented.

Cultivating Leadership: Female Leaders In The Royal Bahamas Defense Force, Jason Styles, Lisa Knowles, Kutisha Ebron

The Journal of Values-Based Leadership

Lessons learned from the impact of COVID-19 have significant implications on crisis management for those serving in the military. Leadership must bear the full brunt of directing subordinates while addressing the crisis at hand. So how do we learn from those volatile, uncertain, complex, and ambiguous (VUCA) situations that arise with no notice? Even more so, those in leadership positions in military branches are instrumental as first responders coming to the national aid of their people. Females continue to enter nontraditional occupational roles, including joining the ranks of leadership in military organizations. This is true in the Royal Bahamas Defense …

Rupert Murdoch: Altruism Inverted, Elizabeth Summerfield

The Journal of Values-Based Leadership

American entrepreneur, television producer, media owner and philanthropist, Ted Turner, once described Rupert Murdoch as “the most dangerous man in the world” (Beahm, 1). This is not an unusual judgement. But it is also one which may contribute to sustaining the Murdoch “brand”, his notoriety and appeal to supporters.

This article examines the deep origins of Murdoch’s cynical worldview, and the source of an ambition that drove him from ownership of a small provincial Australian newspaper to global media mogul. What compelled the need to disseminate often dangerously divisive views on as large a stage as possible, while purporting to …

Remote Work: How Leaders Impact Employee Wellbeing, Russ Carfagno, Jonas Strömbäck, Cheryl Joyner, Gilbert Franco

The Journal of Values-Based Leadership

Leaders face many challenges in motivating team members including maintaining remote workers' sense of organizational inclusion. Remote work and flexible working arrangements (FWA) have increased the complexity. Flexible working arrangements (FWA) provide value to employees and may help with work-life balance yet FWA can create employee loneliness and contribute to higher turnover. This quantitative study looked at whether leadership behavior affected remote workers’ loneliness, and the intention to quit. An online survey was conducted through LinkedIn sampling 92 adults who worked remotely at least 20 hours per week in the United States. The study found that the leader-member relationship does …

The “Consistent Chameleon”: Values-Driven Leadership Among Social And Business Leaders Doing Social Entrepreneurship, Esthi Nave, Hagai Katz

The Journal of Values-Based Leadership

Changing norms in the organizational world drive new hybrid organizational phenomena that reflect an expectation that businesses will be more values-driven and values-driven social organizations will be more businesslike. However, mixing moral values and hard-nosed business creates contradictions. Indeed, research on social/business hybrids has revealed tensions and challenges. Yet, not enough is known about how social entrepreneurs address these inherent contradictions. We explore this question qualitatively through 25 interviews with two types of social/business hybrid organization leaders and their seconds in command: social entrepreneurs who work solely in the social sector (‘exclusive’) and businesspeople who start social ventures (‘dual’).

Pfas Variation Through A Wastewater Treatment Facility Process, Aaron A. Fuzak, Chad J. Pritchard

2024 Symposium

PFAS concentrations were measured at a wastewater treatment facility to see the effect the treatment process had on PFAS levels. Samples were collected following an initial clarifier, second clarifier, sand filtration system, ultraviolet light purification system, and then from the effluent produced by the facility and analyzed using EPA Method 533. The effluent from the treatment facility flows from a pipe that enters a wetland, where it evaporates or infiltrates the groundwater. Municipal and septic treated systems are considered possible point sources for PFAS contamination in groundwater. Sampling levels of PFAS after treatment will give insight into the concentrations and …

Historical Structural Analysis Of The Rileyville Quadrangle, Page County, Virginia, Sydney Fergen

2024 Symposium

The Northwest corner of Virginia, within the Appalachian Mountains, formed during a collision of continents called the Alleghenian Orogeny roughly 250 million years ago(Ma). This event caused tectonic plates to collide, reforming the fractured continental crust back into a new supercontinent, Pangaea. This process took over 100 Ma and closed the Rheic Ocean. These large-scale compressional tectonics had several effects including formation of the Allegheny Plateau and Taconic Mountain range, which has gradually eroded exposing a series of plunging folds and imbricated thrust faults. This poster presents a structural analysis of the Rileyville quadrangle to help decipher regional geologic history …

U/Pb Zircon Ages Of Saltese Upland Conservation Area, Priest River Core Complex, Jessica M. Lawrence, Natalie Potter, Chad Pritchard

2024 Symposium

The Saltese Upland Conservation Area provides a window into the Priest River Core Complex with Lake Hauser gneiss grading to migmatite, garnet-baring amphibolite juxtaposed with felsite to orthogneiss rocks. U/Pb ages from LA-ICP-MS of separated zircon grains show trends very similar to detrital 207Pb/206Pb ages of the Belt Supergroup. The amphibolite displays a much stronger peak at 1.4 to 1.5 Ga , possibly related to the emplacement of Mesoproterozoic dikes. The amphibolite and granitic rocks also contain a number of grains with 238U/206Pb around 60 Ma preserving events from the uplift of the Priest River Complex in the Spokane area. …

Paleohydraulic Analysis Of Megaripples From Outburst Floods In Omak, Washington, Jessica M. Lawrence

2024 Symposium

Located in Omak, Washington atop what is observed to be a gravel point bar are giant current ripples associated with outburst floods that took place during the Pleistocene (O’Connor et al. 2020 and Minard 1985). Thorough breakdown of these giant current ripples was conducted using their geomorphologies associated with stream flow mechanisms for gravel bedforms such as hydraulic radius of cross- sectional area and velocity using Manning’s equation to determine Froude’s Number (USDA 2007). Ripple index associated with ripple wavelength and height was then compared to additional megaripples located throughout Scablands of Washington that have been correlated to the Great …

Synthesis And Analysis Of Borazine Polymers, Kayla M. Besel

2024 Symposium

Plastics and polymers are incredibly useful and ubiquitous in our daily lives but they are incredibly persistent in the environment, killing more than 1.1 million seabirds and animals each year and the global production of plastic has doubled since 1950.¹ A potential path to eliminate this problem is to create polymers that biodegrade or breakdown over time or in certain conditions. Three distinct degradable polymers were synthesized. The synthesis, characterization, and kinetics monitored by UV/Vis over a range of pH’s will be discussed.
