Leadership Perceptions Of Employee Identity: How Leaders Facilitate An Inclusive Environment, Arian Sullivan

Dissertations and Theses @ UNI

Workers spend one-third of their lives at work. Therefore, they deserve to work for organizations that focus on equity and inclusion. Despite laws that aim to protect employees, workers still experience discrimination. This thesis explores how leaders perceive their role in fostering an inclusive culture that encourages employees to bring forward workplace concerns. Through qualitative interviews with locally recognized leaders, this study examines how inclusion is understood and enacted in leadership practices. While participants largely demonstrated inclusive leadership values such as shared perspectives, worker empowerment, and collaboration, I found that participants spoke of their employees in terms of personality traits …

The Influence Of Honor Culture Ideology On Juror Decision Making, Aubrey K. Paschal

Dissertations and Theses @ UNI

Culture of honor is a system of cultural beliefs in which one’s honor is seen to be of the utmost importance (Nisbett & Cohen, 1996). Due to the importance of personal honor, defending one's honor could be seen as an adequate defense for crimes committed in the name of personal honor. This study examined the influence that honor culture ideology has on juror decision making. A total of 190 participants read a brief trial summary of either a crime in which the participants’ honor was threatened, or a crime that did not involve a threat to the defendant’s honor. The …

From Grades To Growth: Exploring Student Perceptions Of Standards-Based Grading, Feedback Utilization, And Teacher–Student Relationships, Meghan Koellner

Dissertations and Theses @ UNI

Many schools have transitioned from traditional grading practices to standards-based grading practices. A central feature of standards-based grading is the use of feedback to move learning forward. When students feel connected to their teachers, they are more likely to engage with feedback and improve their performance. The purpose of this study was to explore how midwestern high school students characterize their experience with standards-based grading, utilize teacher feedback, and perceive the impact of these practices on teacher-student relationships. Three research questions guided this study: (1) How do midwestern high school students characterize their experience with standards-based grading? (2) How do …

Limiting H1n1 Replication Via The Dsrnai Pathway Using Sequence-Specific Ldsrna, Shawn Marie Sharon Carr, Stephanie Dewitte-Orr

Theses and Dissertations (Comprehensive)

The seasonal influenza virus causes a common respiratory illness that can be life threatening to the immunocompromised, the very young, and the elderly. The current strategies for avoiding a serious influenza virus infection are good hygiene practices and the annual influenza vaccine. Unfortunately, last year’s influenza virus vaccine effectiveness ranged between 32-60% for children and adolescents and 46-54% for adults. These low efficacy rates are due to the vaccine often targeting hemagglutinin, a highly variable surface protein. This thesis seeks to create a prophylactic treatment via the RNA interference (RNAi) response that targets the virus’s conserved genes that are integral …

Immune Pathway Modulation In Melanoma Using Chitosan Nanoparticle-Mediated Dsrna Delivery, Bethel C. Iwuji

Theses and Dissertations (Comprehensive)

Cancer is a group of diseases characterized by abnormal and uncontrolled cell division, which typically results in the formation of tumours. Even with advances in treatments, cancer remains one of the leading causes of death globally. Melanoma is an aggressive form of skin cancer which is highly malignant, develops in the pigment-producing cells of the skin, melanocytes, and in the late stages of the disease poses a significant challenge for therapeutic intervention due to its multidrug resistance. The innate immune system is the first line of defence against invading pathogens, including viruses, bacteria, and fungi, and can recognize and destroy …

The Influence Of Self-Efficacy On Support Provision In People With Low Self-Esteem, Daniella Rinaldo

Theses and Dissertations (Comprehensive)

People with lower self-esteem (LSEs) tend to underestimate their capabilities and are reluctant to provide support to close others. The literature has primarily focused on how self-esteem affects individuals as support recipients. However, less is known regarding how to improve LSEs’ reluctance and perceived capabilities as support providers. The present research examines how LSEs could be led to be more willing to provide support to a close other through enhancing their support self-efficacy. I also examined whether LSEs (vs higher self-esteem; HSEs) differ in their abilities and perceptions of the support they provide. I hypothesized that encouraging LSEs to see …

Evaluating The Credibility Of Online Websites: A Digital Information Literacy Program, Emily C. Wood, Kim P. Roberts

Theses and Dissertations (Comprehensive)

The plethora of information currently available via the internet is greater than ever before. Given this, finding credible information is an exceedingly complex task for any information consumer, but especially so for children. Research shows that children have difficulty evaluating the credibility of online information and are more susceptible to believing misinformation compared to adolescents. While a growing body of research addresses children’s internet use, most research focuses on technology safety rather than the evaluation of online information. Several studies have found digital information literacy (DIL) interventions to be successful at increasing critical thinking and awareness of the criteria to …

Crime Modeling Using An Integrated Cnn–Lstm Architecture With Embedded Self-Excitation, Pawandeep Kaur

Theses and Dissertations (Comprehensive)

It is often assumed that natural phenomena occur randomly over time. However, careful analysis reveals that these events typically form some series or sequences and exhibit distinctive temporal patterns. These patterns are not exclusive to nature. They also appear in human activities, often studied under the concept of bursty human dynamics. The statistical methods analyzing bursty human dynamics not only capture overall trends or seasonality but also explore how past events influence future ones. It makes the analysis more realistic and the results more closely aligned with reality. Bursty human dynamics can be studied at two levels: the individual level …

Integrating Indigenous Values And Community Strengths To Achieve Indigenous Food Sovereignty And Community Well-Being In The Ka’A’Gee Tu First Nation, Northwest Territories, Jennifer K. Temmer

Theses and Dissertations (Comprehensive)

Northern Indigenous communities face disproportionate impacts from interconnected challenges related to climate change, food security, health, and cultural preservation, that threaten traditional food systems and practices. While there is a growing recognition of the importance of community-driven solutions, existing frameworks fail to integrate Indigenous values and local priorities effectively. This research addresses this gap by exploring how the Ka’a’gee Tu First Nation (KTFN) is responding to these crises through climate change adaptation efforts focused on food system sustainability as a pathway to self-sufficiency and community well-being. To contribute to these efforts, this dissertation uses Participatory Action Research to facilitate community-driven …
