The Existential Turn: An Adventist Response, Stephen Yeagley

Journal of Adventist Youth and Young Adult Ministries

Youth ministry has taken several “turns” in the late 20th and early 21st centuries, culminating in the current existential turn. This latest shift acknowledges a more diverse youth demographic (Gen Z) concerned with identity, significance, purpose, belonging, and survival. Numerous existential threats have contributed to this generation’s unprecedented mental health crisis. Nevertheless, members of Gen Z are determined to meet these threats and create the conditions for all to flourish. This paper seeks to articulate a supportive and uniquely Adventist response to the existential turn in the form of Sabbath rest.

Optimizing Field-Linked Simulations Of Dry Season Uptake And Monsoon Infiltration Within An Aspen-Mixed Conifer Forest, Raymond J. Hess

Master's Theses

Climate models forecast that headwater catchments in the western U.S. will undergo a reduction in snowpack, early season snowmelt, and increases in evapotranspiration. The resulting extended dry season will stress vegetation in mountainous watersheds throughout the Upper Colorado River Basin. We investigate infiltration patterns and root water uptake in response to dry season disturbances within the East River watershed in Colorado. To do this, we collected soil cores, measured matric potential and sap flow, and monitored tree xylem and soil for stable isotopes of water (2H, 18O) in two soil profiles to 90 cm depth (with three Engelmann spruce and …

I Can't Look Away: Parasocial Relationships With Dance Mom Characters Across Tv And Social Media, Kennedy Kay Pirlet

Electronic Theses and Dissertations

In 2019, Dance Moms ended its airing on Lifetime at the completion of the eighth season. However, the show and its cast members remained popular on social media platforms like TikTok, but we still didn’t know the relationship between watching the show and following cast members on multiple social media platforms or who audiences were closest to. To answer this question, the celebrity-persona parasocial interaction scale and experience of parasocial interaction scale were utilized. These scales were used in this study and found reliable. Snowball recruitment focusing on social media platforms and emails yielded 180 eligible sample participants. Through a …

Organizational Culture's Impact On Job Satisfaction: A Reconceptualization Of The Competing Values Framework, Isaac Thor Erickson

Electronic Theses and Dissertations

Academic job satisfaction has been decreasing in the U.S. which has profound negative impacts such as burnout and decreased well-being of employees. One way that job satisfaction can be increased is through understanding and changing organizational cultures through better communication. The Competing Values Framework (CVF; Quinn & Rohrbaugh, 1983; Belasen & Frank, 2010; Lund, 2003) has been used to understand how organizational cultures and their communicative norms relate to job satisfaction. However, the CVF relies on categorical measures sitting on two axes that are not orthogonal. As such, the study posits breaking these two axes into four dimensions of organizational …

Advancing Karl Jaspers: The Connection Between The Theory Of Existential Communication And Mentoring Satisfaction, Nolan Patrick Bowers

Electronic Theses and Dissertations

Existential philosopher Karl Jaspers’s theory (1932/1970; 1935/1971b) of existential communication is understood to be his most important contribution to existentialism. Additionally, this theory has unique ties to the phenomena of communication, begging its use as a dialogic theory. However, Jaspers’s theory has been relatively untouched by academia. This thesis understands the theory of existential communication through an operationalization of its aspects and explicitly connecting them to communicative behaviors. These aspects of existential communication are (1) vulnerability, (2) open-mindedness, and (3) equality. This study set out to determine whether these aspects could be found within mentoring relationships and support the aspects …

The Spatial Ecology Of Plains Spotted Skunks In South Dakota: Insights From Species Distribution, Resource Selection, And Co-Occurrence Models, Kara M. White

Electronic Theses and Dissertations

The plains spotted skunk (Spilogale interrupta) is a data-deficient small carnivore native to the central plains of North America that has experienced significant population declines. My dissertation investigates the species’ distribution, habitat associations, and interspecific interactions in South Dakota, providing crucial information for conservation actions. In Chapter 1, I developed ensemble distribution models on a broad scale, incorporating species location data from 1985–2020, environmental factors, and six predictive modeling algorithms. I identified key predictors including mean temperature diurnal range and proportion of area as pasture, and estimated ~31,300 km2 of potential habitat, predominately in eastern South Dakota. In Chapter 2, …

Delivery Of Gemcitabine, Stearoyl Gemcitabine And Paclitaxel Through Plga Nanoparticles And Its Effect On The Desmoplasia Of Pancreatic Cancer Spheroids, Rishabh Bahl

Electronic Theses and Dissertations

Pancreatic cancer is one of the deadliest cancers to treat. The primary cause for the drug resistance is the dense extracellular matrix (ECM) that surrounds the tumor and restricts blood supply. Gemcitabine (GEM) and paclitaxel (PTX) are drugs that are clinically used in the treatment of pancreatic cancer. GEM, however, is rapidly metabolized by cytidine deaminase (CDA) and eliminated from the body, and paclitaxel is a substrate for P- glycoprotein (P-gp) efflux receptors. Drug delivery using nanoparticles has been reported to help improve drug half-lives and bypass efflux receptors. This thesis aims to encapsulate PTX in PLGA nanoparticles (PTX-NP) and …

Increasing Retention Of Women In Hunting And Fishing, Shelby Isensee

Electronic Theses and Dissertations

Despite national declines in hunting and fishing, women are making inroads in historically male-dominated sports. To further encourage women’s participation, states established programs to recruit, retain, and reactivate [R3] hunters and anglers. Women are participating in these programs and other recreational groups to access opportunities to learn skills and grow their networks. Yet, very little is known about what programs are offered for women, what aspects of programs are most effective to support women’s retention in these activities, and what women’s hunting and fishing groups are available across the landscape. To address these questions, I collected qualitative data from participant …

Respiratory Disease In Bighorn Sheep: A Varied Investigation Of Immunization, Transmission, And Detection, Katelin Frerichs

Electronic Theses and Dissertations

Respiratory disease has historically been recognized as a limiting factor to wild bighorn sheep (Ovis canadensis) herds throughout North America with epizootics resulting in large-scale die offs and reductions in recruitment. The primary etiologic agent associated with pneumonia outbreaks in bighorn sheep is Mycoplasma ovipneumoniae. This bacterial pathogen is frequently carried asymptomatically by domestic sheep (Ovis aries) and goats (Capra hircus); however, when these domestic hosts come in contact with and spread this pathogen to bighorns, the disease can cause epizootics and large-scale mortality. Domestic sheep strains are more commonly detected in bighorn sheep than domestic goat strains, and previous …

Isolation, Molecular Characterization, And Epidemiological Analysis Of An Emerging Avian Metapneumovirus Subgroup B In Us Poultry, Sumit Jangra

Electronic Theses and Dissertations

Avian metapneumovirus (aMPV) is one the most economically important poultry respiratory pathogens belonging to the family Pneumoviridae and genus Metapneumovirus, which can affect both domestic and wild birds. aMPVs are classified into four subgroups (A, B, C, and D) based on the level of genetic variations and antigenic differences. aMPV causes turkey rhinotracheitis (TRT) and swollen head syndrome (SHS) in turkeys and chickens respectively. Recently, outbreaks of respiratory disease in meat-type birds and a significant decline in egg production with respiratory signs in breeders were reported from different states in the USA. Isolating aMPV is challenging as it is a …

Towards A Context-Contingent Stage Theory Of Entrepreneurial Opportunity: Introducing The Petii Model, Xiaohong Iris Quan

Faculty Research, Scholarly, and Creative Activity

Understanding opportunity is a crucial aspect of entrepreneurship research. Existing studies have extensively examined individual factors in facilitating entrepreneurial activities such as new venture creation. Although there are some discussions on contextual factors, few connect context with the origin of entrepreneurship—opportunity. Recognising the objectivity of entrepreneurial opportunity, this theoretical article first proposes two types of opportunities—innovative opportunity and imitative opportunity—to understand the nature of opportunity. It then proposes a systematic framework—the PETII (Population, Economic status, Technological advancement, Industry life cycle, Institutions) model—to analyse the role of context in the distribution of opportunity. Furthermore, it examines how both objective contextual factors …

Vehicular Traffic Flow Prediction Via Decentralized Federated Meta-Learning, Andrew Selvia, Ankur Singh, Wencen Wu

Faculty Research, Scholarly, and Creative Activity

Traffic flow prediction (TFP) has become a crucial problem for billions of people who rely on traffic predictions to optimize their travels every day. In this paper, we present a decentralized federated meta-learning (DFML) framework for traffic flow prediction. Within this framework, traffic detectors spread across a road system can form federations with nearby peers in order to predict traffic collaboratively. A node that assembles a federation assumes the role of receiver while the remainder are assigned as broadcasters. The broadcasters learn model parameters from local data and then broadcast those models to receivers, thereby enriching the available information from …

Multi-Robot Source Seeking And Field Reconstruction Of Spatial-Temporal Varying Fields, Deepak Talwar, Thinh Lu, Divyam Sobti, Wencen Wu

Faculty Research, Scholarly, and Creative Activity

To effectively respond to environmental disasters, real-time monitoring and pollution control rely heavily on the ability to estimate, predict, and reconstruct constantly changing environmental conditions across different locations. In this research, we develop a multi-robot source-seeking and field reconstruction framework that enables a multi-robot group to detect multiple sources within a spatial-temporal varying field and reconstruct the field in real time. The strategy consists of two parts: source seeking and field reconstruction. The source-seeking part features a gradient-based source-seeking controller that directs the multi-robot group toward local sources and a destination selection algorithm that navigates the multi-robot formation beyond the …

Economic Growth Before And After The Fiscal Stimulus Of 2008–2009: The Role Of Institutional Quality And Government Size, André Varella Mollick, Andre Coelho Vianna

School of Economics and Finance Faculty Publications

Governments implemented fiscal stimulus packages to alleviate the global financial crisis of 2007–2009. Using annual data from 1996 to 2019, we investigate economic growth in a large sample of countries for pre-and post-Global Financial Crisis years. Our approach analyzes the interaction between institutional quality and government size (government expenditures as share of GDP), reinforced by threshold estimations. We document that economies react to government size depending on the quality of the institutions in question. First, fixed effects models indicate higher institutional quality has positive effects on growth, while government size—and its interactions with institutional quality—has negative effects. Second, the coefficients …

Characterization Of The Disease-Causing Mechanism Of Kif3b Mutations From Ciliopathy Patients, Jessica M. Adams, Caleb Sawe, Skye Rogers, Jordyn Reid, Ronith Dasari, Martin F. Engelke

Faculty Publications – Biological Sciences

The heterodimeric kinesin-2 motor (KIF3A/KIF3B with accessory protein KAP3) drives intraflagellar transport, essential for ciliogenesis and ciliary function. Three point mutations in the KIF3B subunit have recently been linked to disease in humans (E250Q and L523P) and Bengal cats (A334T) (Cogné et al., Am. J. Hum. Genet., 2020, 106, 893–904). Patients display retinal atrophy and, in some cases, other ciliopathy phenotypes. However, the molecular mechanism leading to disease is currently unknown. Here, we used Kif3a−/−;Kif3b−/− (knockout) 3T3 cells, which cannot make cilia, to characterize these mutations. While reexpression of KIF3B(E250Q) and KIF3B(L523P) did not rescue ciliogenesis, reexpression …
