Mena Terrorism And The West: Explaining Why Terrorist Groups From The Middle East And North Africa Target Western Democracies, Michael A. Defeo
Mena Terrorism And The West: Explaining Why Terrorist Groups From The Middle East And North Africa Target Western Democracies, Michael A. Defeo
UNLV Theses, Dissertations, Professional Papers, and Capstones
Terrorist groups from the Middle East and North Africa (MENA) region remain one of the most formidable threats to international security. While their organization and motives have been significantly different over time, a commonality is that they tend to disproportionately target Western democracies. This dissertation argues that this trend is mainly a consequence of the foreign policies that these states pursue in the region. These policies, in terms of support for Israel and interventionism, are theorized as being the precipitous causes of MENA terrorism. Likewise, it is argued that the democratic institutions and extents of globalization in these states are …
The Impact Of Childhood Experiences On Involvement And Confidence In Social Institutions, Jordan Sydney Donohue
The Impact Of Childhood Experiences On Involvement And Confidence In Social Institutions, Jordan Sydney Donohue
UNLV Theses, Dissertations, Professional Papers, and Capstones
Childhood is made up of a wide array of both negative and positive experiences. One potential negative childhood experience may be understood as childhood maltreatment. Childhood maltreatment consists of physical abuse, sexual abuse, emotional abuse, or neglect prior to age 18 (World Health Organization, 2020). Neighborhood, family, and school dynamics are other areas in a child’s life that may create difficulties and challenges. Prior research has concluded that negative outcomes are associated with poor school, community, and family dynamics (Coulton, 2007; Lansford, 2009; Split et al., 2012). Previous research has also examined the impact of childhood maltreatment on different domains …

Information-Theoretic Model Diagnostics (Infomod), Armin Esmaeilzadeh
UNLV Theses, Dissertations, Professional Papers, and Capstones
Model validation is a critical step in the development, deployment, and governance of machine learning models. During the validation process, the predictive power of a model is measured on unseen datasets with a variety of metrics such as Accuracy and F1-Scores for classification tasks. Although the most used metrics are easy to implement and understand, they are aggregate measures over all the segments of heterogeneous datasets, and therefore, they do not identify the performance variation of a model among different data segments. The lack of insight into how the model performs over segments of unseen datasets has raised significant challenges …

High-Yield Bioinspired Atmospheric Water Capture Through Hydrogels, Yiwei Gao
High-Yield Bioinspired Atmospheric Water Capture Through Hydrogels, Yiwei Gao
UNLV Theses, Dissertations, Professional Papers, and Capstones
Water scarcity is a global issue affecting billions of people, and atmospheric water harvesting (AWH) technology has been identified as a potential solution. However, existing single-material AWH approaches have limited water harvesting yields due to alternated water capture, storage, and release stages, and only function within a high relative humidity range. In my doctoral research project, we developed a bio-inspired, hydrogel-based multi-layer AWH approach that allows for segregated capture, storage, and release stages, and is envisioned to have higher daily water harvesting efficiency even in low-humidity areas. My research began with understanding the relations between hydrogel mechanical stiffness, hydraulic permeability, …

Maternal Health In The Context Of Social, Political, And Economic Change Among Hadzabe Foragers Of Tanzania, Kristen Herlosky
UNLV Theses, Dissertations, Professional Papers, and Capstones
Many low and middle-income countries have implemented new national policy measures aimed at reducing maternal morbidity and mortality due to globalized efforts to improve women’s maternal health. One of the main goals is to move childbirth into hospital facilities and improve health access and education outreach. For Indigenous communities around the world, these measures have fallen short of their goals. Indigenous women suffer from greater social, political, and economic disparities and inequalities, have poorer health indicators overall, and worse maternal health outcomes compared to their non-Indigenous counterparts. For small-scale communities, we have limited data on reproductive health among women, specifically …
The Closing Of One Black Box, The Opening Of Another: A Self-Study Of How An Instructional Coach Makes Decisions, Andromeda L. Hightower
The Closing Of One Black Box, The Opening Of Another: A Self-Study Of How An Instructional Coach Makes Decisions, Andromeda L. Hightower
UNLV Theses, Dissertations, Professional Papers, and Capstones
Despite the efforts of traditional and alternative teacher education programs (i.e. pre-service teacher education) in the United States, teachers frequently report feeling unprepared by the time they begin teaching full time in the classroom. Teachers with low levels of self-efficacy are correlated with lower job satisfaction, higher levels of stress and anxiety, and lower student achievement gains in the classroom. To assist with ameliorating these gaps, schools, districts, and private distributors provide training opportunities for teachers once they have begun the job (i.e. in-service teacher training) in the form of teacher professional development. Mainstream professional development approaches are traditionally simplistic …

Spectroscopic Studies On Silicon And Chalcopyrite Materials For Solar Energy Applications, Amandee Hua
Spectroscopic Studies On Silicon And Chalcopyrite Materials For Solar Energy Applications, Amandee Hua
UNLV Theses, Dissertations, Professional Papers, and Capstones
In this dissertation, silicon-based materials for photovoltaics and chalcopyrite-based materials for photoelectrochemical water splitting are investigated using various spectroscopic and microscopic techniques. Although silicon dominates the photovoltaic market, further improvement can be made by using an alternative low temperature passivation approach. Currently, thermally grown SiO2 passivation is commonly used for silicon solar cells. However, this technique requires high processing temperatures (>800 °C), which increases the thermal budget, potentially decreases the bulk quality of Si, and can lead to difficulties in implementing in production lines. Here, a S-based passivation approach is studied that require lower processing temperatures of ~550 °C. …

Several key observations are made, relating to the phase transition of ice-VII to X, an intermediate phase I have named ice-VIIt and evidence of a post ice X phase. Some of these experiments have been replicated using D2O ice as well, in order to gain insight into nuclear quantum …
Individual Differences In Police Officers’ Decision Styles In Order Maintenance Policing, Damarrah Elisheba Jameson
Individual Differences In Police Officers’ Decision Styles In Order Maintenance Policing, Damarrah Elisheba Jameson
UNLV Theses, Dissertations, Professional Papers, and Capstones
Day-to-day police work tends to be in order maintenance policing. These encounters necessitate officer discretion in decision responses to manage them. These decision responses reflect an officer’s decision style which precedes the encounter and drives subsequent decision making to manage them. However, little is known about officer-level decision style. For example, whether an officer has a rational, intuitive, dependent, avoidant, or spontaneous decision style (Scott& Bruce, 1995). Police training in any format often lacks attention to decision styles. As such, an officer’s decision style is most likely associated with demographics (e.g., age, gender) and occupational self-efficacy – a reflection of …

UNLV Theses, Dissertations, Professional Papers, and Capstones
Assistance dogs can mitigate the effects of an individual’s disability. Occupational therapists consider the whole being when providing interventions through the individual’s meaningful occupations to improve health, well-being, and quality of life. Occupational therapists can make referrals or become a valuable team member for clients who wish to explore assistance dogs as an assistive technology option to improve physical, mental, and psychosocial considerations for increased independence in their clients. Few occupational therapy practitioners are educated about the benefits and disadvantages of the partnership between assistance dog and handler. Therefore, they are unable to adequately recommend assistance dogs for their clients, …
Differential Effects Of Extracellular Matrix Glycoproteins Fibronectin And Laminin-5 On Dental Pulp Stem Cell Phenotypes And Responsiveness, Hyungbin Lee
UNLV Theses, Dissertations, Professional Papers, and Capstones
Dental pulp stem cells (DPSCs) are mesenchymal stem cells (MSCs) with the potential to differentiate in a limited number of other tissue types. Some evidence has suggested the modulation of DPSC growth may be mediated, in part, by exogenous extracellular matrix (ECM) glycoproteins, including fibronectin (FN) and laminin-5 (LN5). Although preliminary research suggests that some ECM glycoproteins may work as functional biomaterials to modulate DPSC growth responses, the primary goal of this project is to determine the specific effects of FN and LN5 on DPSC growth and viability.Using an existing DPSC repository, n = 16 DPSC isolates were cultured and …
