Use Of Interlaboratory Studies For The Development Of Consensus-Based Criteria For The Elemental Analysis Of Electrical Tapes, Lacey M. Leatherland

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tape evidence is often used in criminal cases involving violent crimes, kidnappings, improvised explosive devices (IEDs), and drug trafficking. This evidence can reveal potential links between suspects, items, or scenes. The forensic examination of electrical tape can provide investigative leads or offer support to alternative hypotheses evaluated in the courtroom. A conventional analytical scheme includes microscopic examination, Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy Energy Dispersive Spectrometry (SEM-EDS), and Pyrolysis Gas Chromatography Mass Spectrometry (Py-GC/MS). Elemental analysis of electrical tapes is commonly achieved using SEM-EDS; however, recent scientific literature suggests that this analysis can evolve from using SEM-EDS to …

Light Wavelength Modulates Search Behavior Performance In Zebrafish, Matthew Reid Waalkes

Graduate Theses, Dissertations, and Problem Reports (ETD)

Long-term internal states drive many behaviors in animals. Zebrafish is a common vertebrate model conducive to finding the neural coding to these behaviors. In the Horstick lab, the larval zebrafish light search behavior is central to our research. This behavior, which is the locomotor response to the loss of light in larval zebrafish, is controlled by multiple neural populations that drive different internal states. The sensory neurons initially responsible for this behavior are photosensitive due to the expression of light-absorbing proteins called opsins. Opsins vary in the ranges of wavelengths of light that they absorb, and are expressed in distinct …

Comparing Resurgence Following Positive And Negative Reinforcement Using A Human-Operant Approach, Abbie Cooper

Graduate Theses, Dissertations, and Problem Reports (ETD)

Resurgence is a type of relapse that consists of the recurrence of a previously eliminated response following worsening reinforcement conditions for an alternative response. Resurgence can occur following a history of positive or negative reinforcement; however, no previous evaluations have directly compared resurgence following these processes. In the present set of experiments, college students responded on a computer program to earn points (positive reinforcement) and to avoid losing points (negative reinforcement). Experiment 1 evaluated resurgence when both target and alternative responses were maintained by the same reinforcer class (i.e., in the positive-reinforcement component the target and alternative responses were positively …

Reconstructing Δ14c Production Events Using Tree Rings: Does Tree Physiology Affect Estimates Of Atmospheric Δ14c?, Meagan Rory Walker

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cosmic rays and solar energetic particles (SEP) bombard the Earth’s geomagnetic field, posing a threat to satellites, space stations, and human space exploration. These rays and particles also produce radiocarbon (¹⁴C) in Earth’s atmosphere, thus records of past ¹⁴C concentration in the atmosphere may be indicative of past cosmic and solar activity. Rapid increases in the concentration of atmospheric radiocarbon ¹⁴C, (Miyake events) first identified in tree rings, are thought to be a result of solar eruptive activity triggering the release of solar energetic particles, though the precise nature of past events remains unresolved.

Why Leadership Needs History, Paul W. Sanders, Martin Gutmann

Interdisciplinary Journal of Leadership Studies

What contribution can a leadership focus make to arbitrating the catch-22s and wicked problems of the ongoing polycrisis? Not much, if you were to turn for advice to mainstream leadership studies (LS), a field of enquiry that continues to see itself, above all, as a tool for optimizing corporate performance and effectiveness. One way in which LS can escape its current tunnel vision and lack of relevancy is to return to its own roots and rehabilitate the historical approach. Historical LS can add value in several areas: it has the ability to deliver insightful case studies that provide useful analogies, …

Molecular Origins Of Phase Stability In Phase-Change Nano-Emulsions For Thermal Energy Storage By Nmr Spectroscopy, Jungeun Park

Dissertations and Theses

Phase change materials (PCMs) are latent heat storage materials that can store or release thermal energy during phase transitions. Organic PCM nano-emulsions are formed by emulsifying oil in water in the presence of surfactants, enhancing thermal conductivity and pumpability. However, PCMs nano-emulsions can become unstable due to repeated thermal cycling and shear in heat transfer systems.

To better understand the molecular origins of phase instability in PCMs nano-emulsions, liquid-state nuclear magnetic resonance (NMR) measurements were applied to a model PCM nano-emulsion. Quantitative ¹H single-pulse NMR measurements established the liquid fraction of oil within nano-emulsions as a function of temperature, …

Understand The Structure-Water-Responsive Relationship By Engineering Silk Materials, Yeojin Jung

Dissertations and Theses

Water-responsive (WR) materials mechanically swell and shrink in response to changes in relative humidity, and they have demonstrated the capability to exert higher actuation energy than conventional actuators and artificial muscles. As a result, WR materials have recently gained attention as potential high-energy actuating components for engineering applications. Despite the growing interest in this emerging category of WR materials, the fundamental WR mechanism of their significant performance is still not fully understood, limiting the ability to rationally design engineered systems.

One radical means that has been proposed within …

Parasympathethic Nervous Activity And Social Exclusion In Borderline Personality Disorder, Rebecca E. Barnes

Dissertations and Theses

Abstract

The experience of being excluded is universally unpleasant. However, for individuals that suffer from Borderline Personality Disorder (BPD), the experience of social exclusion, or ostracism can be unbearable (Bortolla, et al., 2019). While there is a significant amount of research on physiological reactivity in BPD, no studies adequately connect the parasympathetic nervous system (PNS) responses of people with BPD to social exclusion which is critical to understand as the inability of the PNS of individuals with BPD to adapt to stressors may be a contributing factor to the elevated rate of suicide and suicide attempts in this clinical population …

Teach Them How To Say Goodbye: Student Therapist Termination At A Psychodynamic Training Clinic, Michael Ferrara

Dissertations and Theses

Termination is arguably one of the most important aspects of psychotherapy, however, the research into training for termination is sparse. Further, student therapists report that their training for termination provided little guidance, instruction, or acknowledgment of clinical realities around treatment endings. Using a semi-structured interview with a sample of 11 student therapists at a psychodynamic training clinic, this study explored experiences of termination and the preparation for those endings. Qualitative thematic analysis indicated that this group of student therapists did not experience shared and structured termination training but did not feel they were unprepared for the endings with their patients. …

Identity-Focused Therapist Self-Disclosure In Matched Sexual/Gender Minority Dyads: A Longitudinal Therapy Process-Outcome Study, Brian Thomas Neff

Dissertations and Theses

Therapist self-disclosure (TSD) is a controversial clinical intervention whose benefits and drawbacks remain contested. Notably, no prior research has differentiated explicitly between self-disclosures related to the therapist’s core identities and those peripheral to identity, and qualitative studies suggest that identity-focused therapist self-disclosure (TSD-I) may be beneficial when therapist and patient share at least one marginalized identity. LGBTQ+ people, who experience significant health disparities and utilize psychotherapy more than their heterosexual and cisgender counterparts, could benefit particularly from TSD-I. The mental and physical health challenges facing LGBTQ+ individuals are predominantly explained through minority stress theory, which suggests that societal prejudice and …
