The Biltmore Forest School And The Establishment Of Forestry Education In America, Dan Barry Croom

Journal of Research in Technical Careers

The Biltmore Forest School, despite its unusual existence within the affluent Biltmore Estate, played a crucial role in the early 20th-century American forestry movement. Founded by Carl A. Schenck and supported by George Vanderbilt II, the school aimed to educate foresters and promote sustainable forest management. However, many aspects of the Biltmore experiment failed due to the new and untested nature of forestry science in America. This experiment exposed a fundamental divide in forestry education, with Gifford Pinchot advocating for conservation-centered teaching while Schenck believed in the economic viability of lumber production. Ultimately, the Biltmore Forest School offered valuable vocational …

Assessing The Potential For Magmatic Sulfides Within Southwestern Laurentia Large Igneous Province, Thomas J. Boes

UNLV Theses, Dissertations, Professional Papers, and Capstones

The ~1.1 Ga magmatism of the Southwestern Laurentia Large Igneous Province (SWLLIP) generated a series of mafic-ultramafic sheets, sills, and dikes emplaced within Mesoproterozoic sedimentary units and older crystalline basement rock throughout the southwest United States and northern Mexico. This large igneous province (LIP) event remains enigmatic in identifying the processes that generated this magmatism. In addition, potential links to the contemporaneous magmatism of North America's magmatic Ni-Cu-platinum group element (PGE) mineralized Mid-Continent Rift (MCR) LIP to the northeast of the SWLLIP remain unclear. The contemporaneous 1.1 Ga MCR LIP event hosts economically viable magmatic sulfide deposits in the Duluth …

An Examination Of The Teaching And Learning Of Resonance In General Chemistry I And Organic Chemistry I Using Variation Theory, Sabrina Barakat

UNLV Theses, Dissertations, Professional Papers, and Capstones

Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I, reintroduced in Organic Chemistry I, and then utilized throughout other higher-level chemistry courses. A molecule or ion can be said to exhibit resonance when it can be represented by two or more chemical structures (i.e., Lewis structures) that differ only in their arrangement of electrons. In other words, resonance represents the electronic structure of a molecule or ion when a single Lewis structure does not adequately depict the true distribution of electrons. The molecule or ion is best represented as a combination of all of the …

Racial Microaggressions Research: Intersectionality, Coping Strategies, And Groups Impacted, Aldo M. Barrita

UNLV Theses, Dissertations, Professional Papers, and Capstones

Microaggressions, a term first coined to name everyday experiences with oppression five decades ago (Pierce et al., 1977), has evolved in the literature naming specific aggressions taking place in microsystems targeting minoritized groups (Sue et al., 2007). However, as this research area expands, a need for specificity about who is being impacted by racial microaggressions and how this impact takes place remains a gap in the literature that the research program of this dissertation aimed to address. Expanding from traditional racial microaggression approaches (Sue et al., 2019; Williams et al., 2021), this dissertation incorporates aspects of intersectionality, coping strategies, and …

Differential Expression Of Microrna Mir-145 And Mir-155 Downstream Targets In Oral Cancers Exhibiting Limited Chemotherapy Resistance, Conner Belnap

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: New evidence has suggested that non-coding microRNAs play a significant role in mediating and modulating chemotherapy resistance, particularly among oral cancers. One recent study found that the expression of miR-145 and lack of miR-155 expression strongly correlated with a limited chemotherapy resistance to Cisplatin, 5-Fluorouracil and Paclitaxel , although the mechanism(s) responsible for these observations remain unidentified.

Methods: Using commercially available cell lines of oral squamous cell carcinoma (OSCC), RNA was isolated using phenol:chloroform extraction. The isolated RNA was converted into cDNA by reverse transcription and subsequently screened for the presence or absence of downstream targets of miR-145 and …

Improving Patients’ Readiness For Discharge: The Development Of An Occupation-Based Group Therapy Protocol In Inpatient Rehabilitation, Valerie Cheng

UNLV Theses, Dissertations, Professional Papers, and Capstones

The literature showed a lack of studies involving occupation-based group therapy in an inpatient rehabilitation setting, with notable barriers including lack of time, space, and equipment. The barriers lead occupational therapists (OT) to pursue an impairment-based approach, steering away from occupation-based approaches, which is what makes up the core of OT. Current literature is also limited to patients' perceptions of discharge readiness, with most research primarily concentrated on clinicians' perspectives. This 14-week capstone experience will include developing an occupation-based group therapy protocol for inpatient rehabilitation that will be implemented at Dignity Health Rehabilitation Hospital. Through conducting occupation-based group therapy in …

Perceptions Of A Community-Based Playgroup To Promote Caregiver Knowledge Of Resources And Prevention Of Developmental Delays In A Rural Setting, Chesnee Clingman

UNLV Theses, Dissertations, Professional Papers, and Capstones

For children living in rural communities, the likelihood of having a developmental delay substantially increases compared to children living in urban areas (Weglarz-Ward et al., 2019). This can be due to a lack of access to resources, limited education, and geographical isolation. Despite the rising trend of developmental delays among rural children, there is a noteworthy lack of early intervention resources for both the child and their family. This trend of minimal resources is demonstrated in Lincoln County, Nevada. Using an occupational therapy lens, a community-based playgroup program was developed for residents in Lincoln County. Community-based playgroups involve a structured …

Causal Attribution Tendencies Of Early Childhood Practitioners And The Efficacy Of Attribution Retraining, Alex J. Faucheux

UNLV Theses, Dissertations, Professional Papers, and Capstones

Early childhood practitioners frequently attempt to identify the cause of outcomes experienced by their learners. This is sometimes referred to as causal attribution. Causal attribution may be affected by prior success and failure of a learner, the amount of effort exerted by the learner, the ability level of the learner, and knowledge of any disability associated with the learner, all of which can be considered controllable or uncontrollable, stable or unstable, and internal or external (Weiner, 1986; Woodcock & Vialle, 2011). As practitioners attribute cause to outcomes, they start to develop attributional tendencies; these tendencies, along with the cues and …
