New-R Intervention For Clients With Severe Mental Illness And Obesity: Grant Writing For Implementation Funds Supporting Occupational Therapy Interventions, Kaitlyn Hoffman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Increasing numbers of people suffer from obesity and severe mental illness co-morbidly. If these conditions remain untreated, they can harm an individual's health and well-being. Unfortunately, there are very few programs currently available that target both management and improvement of these conditions simultaneously. Even so, despite the lack of programming options, it must be noted that the NEW-R program strives to reach those goals, although there hasn't been an abundance of literature supporting the effectiveness of this program. This poses a concern for occupational therapy practitioners who hope to assist their clients in managing these conditions as occupational therapy treatments …

Response Of The Isothermal Mode Grüneisen Tensor Across Phase Boundaries, Jasmine K. Hinton May 2023

Response Of The Isothermal Mode Grüneisen Tensor Across Phase Boundaries, Jasmine K. Hinton

UNLV Theses, Dissertations, Professional Papers, and Capstones

The assumptions for the 1912 Grüneisen parameter are reviewed, particularly in the cases of anisotropy, high temperatures, and across phase boundaries. Two main case studies are shown: β-Sn, and Cd. The main techniques of this work involve resistively heated diamond anvil cells with both optical Raman spectroscopy and x-ray diffraction. It is found in Sn that the isothermal mode Grüneisen tensor along increasing isotherms diverges from the single-valued temperature aggregate at the onset of melt, and this is proposed to use as a method of exploring melt phase boundaries in other systems. This method is examined once again on another …

Individual Differences In Police Officers’ Decision Styles In Order Maintenance Policing, Damarrah Elisheba Jameson May 2023

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 …

The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk May 2023

The Influence Of Prediction Error Strength On Reconsolidation, Kevin D. Mohawk

UNLV Theses, Dissertations, Professional Papers, and Capstones

It has been well established that consolidated memories can be reactivated and enter a labile state where they are once again vulnerable to modification. Reactivated memories, therefore, need to be restabilized or reconsolidated. Prediction error (PE) is one of the most common ways of reactivating consolidated memories, yet no studies have examined how varying the strength of PE influences reconsolidation. The present study aimed to determine if the strength of PE is an important factor for triggering reconsolidation and if so, how PE strength influences the reconsolidation process, whether through strengthening or weakening the memory. To vary PE strength, participants …

The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski May 2023

The Effect Of Sleep And Emotion On Pattern Separation, Alanna N. Osmanski

UNLV Theses, Dissertations, Professional Papers, and Capstones

Prior work on the relationship between sleep and memory suggests that the sleep state is an optimal time for memory consolidation to occur. During slow wave sleep, newly encoded information in the hippocampus is repeatedly activated, driven by slow oscillations that originate in the neocortex. This process that occurs during slow wave sleep facilitates the long-term storage of memories. A widely accepted view of emotion and sleep is that emotional memories are preferentially consolidated during sleep so that they are easily accessible for retrieval, whereas neutral memories tend to be less accessible. However, recent meta-analyses of sleep, emotion, and memory …

Systemic Theoretical Instruction: Tense And Aspect In Italian A Sociocultural Study Of American Learners Of Italian, Charles Joseph Panarella, Jr. May 2023

Systemic Theoretical Instruction: Tense And Aspect In Italian A Sociocultural Study Of American Learners Of Italian, Charles Joseph Panarella, Jr.

UNLV Theses, Dissertations, Professional Papers, and Capstones

University-level language and second-language classrooms typically use general rules of thumb to teach grammar without considering its conceptual aspects and cultural origins. These general rules of thumb are normally taught using a communicative approach to language teaching which typically places little emphasis on immediate corrective feedback and learner development. Most assessments are static in nature and focus on right and wrong answers rather than their origins (i.e., learner development and microgenesis). The lack of corrective feedback and lack of considering affective factors have the potential to negatively influence language acquisition in terms of motivation and self-efficacy. In addition, foreign language …

Sight Words: Poems, Benjamin Harrison Socolofsky May 2023

Sight Words: Poems, Benjamin Harrison Socolofsky

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sight Words is a collection of poems that questions the image as the central unit of meaning in poetry. Sight words is a lyric bildungsroman, that traces the process of metaphysical alienation that an individual undergoes in the postmodern world. The speaker is exposed to an overabundance of meaning that the visual world transmits and as the order of language deteriorates, meaning multiplies and falters. The language and poetics of Sight Words struggles to reconcile the disconnect between visual language and spoken language. Every missed communication points to a denial of access to the self, which the speaker apprehends as …
