An Examination of Heritage Resource Internship Experiences and Land Management Agency\u27s Role in Inspiring Emerging Leaders

To address the shortage of people seeking to fill employment vacancies, the land management agencies are using the Student Conservation Association (SCA) and internships as a means of recruiting the next generation of leaders. Yet little research has been conducted on internships in cultural and natural heritage resource parks. This study used a two-phase linear exploratory method to investigate the experiences of cultural and natural heritage resource interns. Additionally, the study sought to determine if and how internships shape vocational, recreational, social and personal identities concerning parks and protected areas. Using significant life experiences, environmental socialization and emerging adulthood theories, the first phase consisted of interviewing 25 supervisors and interns who have completed their internship within the past year. During the second phase, a survey instrument was constructed using the themes from the interviews and given to alumni of the SCA as well as alumni from Parks, Recreation and Tourism Management department at a university in the southeast (N=256). Results indicate that memorable childhood experiences in nature are important for recreation and environmental identity but not as necessary for career identity. In contrast, quality internships, mentors and career development play a key role in career identity crystallization during emerging adulthood. This understanding of the impacts that occur during the internship experience helps in judging for whom and in what context internships produced a lifestyle revolving around cultural and natural heritage resources

Free and forced propagation of Bloch waves in viscoelastic beam lattices

Beam lattice materials can be characterized by a periodic microstructure realizing a geometrically regular pattern of elementary cells. Within this framework, governing the free and forced wave propagation by means of spectral design techniques and/or energy dissipation mechanisms is a major issue of theoretical interest with applications in aerospace, chemical, naval, biomedical engineering. The first part of the Thesis addresses the free propagation of Bloch waves in non-dissipative microstructured cellular materials. Focus is on the alternative formulations suited to describe the wave propagation in the bidimensional infinite material domain, according to the classic canons of linear solid or structural mechanics. Adopting the centrosymmetric tetrachiral cell as prototypical periodic topology, the frequency dispersion spectrum is obtained by applying the Floquet-Bloch theory. The dispersion spectrum resulting from a synthetic Lagrangian beam lattice formulation is compared with its counterpart derived from different continuous models (high-fidelity first-order heterogeneous and equivalent homogenized micropolar continua). Asymptotic perturbation-based approximations and numerical spectral solutions are compared and cross-validated. Adopting the low-frequency band gaps of the dispersion spectrum as functional targets, parametric analyses are carried out to highlight the descriptive limits of the synthetic models and to explore the enlarged parameter space described by high-fidelity models. The microstructural design or tuning of the mechanical properties of the cellular microstructure is employed to successfully verify the wave filtering functionality of the tetrachiral material. Alternatively, band gaps in the material spectrum can be opened at target center frequencies by using metamaterials with inertial resonators. Based on these motivations, in the second part of the Thesis, a general dynamic formulation is presented for determining the dispersion properties of viscoelastic metamaterials, equipped with local dissipative resonators. The linear mechanism of local resonance is realized by tuning periodic auxiliary masses, viscoelastically coupled with the beam lattice microstructure. As peculiar aspect, the viscoelastic coupling is derived by a mechanical formulation based on the Boltzmann superposition integral, whose kernel is approximated by a Prony series. Consequently, the free propagation of damped Bloch waves is governed by a linear homogeneous system of integro-differential equations of motion. Therefore, differential equations of motion with frequency-dependent coefficients are obtained by applying the bilateral Laplace transform. The corresponding complex-valued branches characterizing the dispersion spectrum are determined and parametrically analyzed. Particularly, the spectra corresponding to Taylor series approximations of the equation coefficients are investigated. The standard dynamic equations with linear viscous damping are recovered at the first order approximation. Increasing approximation orders determine non-negligible spectral effects, including the occurrence of pure damping spectral branches. Finally, the forced response to harmonic single frequency external forces in the frequency and the time domains is investigated. The response in the time domain is obtained by applying the inverse bilateral Laplace transform. The metamaterial responses to non-resonant, resonant and quasi-resonant external forces are compared and discussed from a qualitative and quantitative viewpoint

Prosecuting the Police: How America’s Criminal Justice System Has Failed Breonna Taylor and Other People of Color

Using the Breonna Taylor case as an example, this thesis will investigate the ways that certain practices and policies in America’s criminal justice system have allowed discriminatory policing to flourish. People of color in America disproportionately experience acts of violence from police officers, and more often than not, there is no justice for these victims. The practices and policies that have been put into place to combat racial injustices in America have been ineffective because of the principles that govern our system. The way that America’s criminal justice system operates is inherently discriminatory and the need for reform is urgent

IMPROVING UNRESTRICTED LINE OFFICER COMMUNITY CORPS LOGISTICS KNOWLEDGE: KEY CONCEPTS AND PROCESSES

Naval leadership has identified the lack of logistics experience as a critical force vulnerability in the Unrestricted Line (URL) community officer corps. They believe this gap will limit the Navy’s ability to sustain operations in contested and constrained environments. As the United States enters a new era of strategic competition with near-peer competitors, increasing the logistical knowledge and educational experiences of the URL community is of paramount importance. Peacetime naval operations have dominated the operational landscape for several decades with logistical support mirroring that static and predictable environment. Strategic competition will challenge the established logistic concepts and those concepts must also change. This project develops case studies to equip URL officers with the necessary mindset to approach and analyze complex logistic concerns. Each case study touches on specific logistics topics, incorporates broader logistical implications, and uses various investigative and analytic tools to help solve real-world problems. Equally important, this study will build a stronger foundation that will make the warfighter more combat effective and further enhance his or her grasp of operational and tactical environments.NPS Naval Research ProgramThis project was funded in part by the NPS Naval Research Program.Lieutenant Commander, United States NavyLieutenant Commander, United States NavyApproved for public release.

High-power Magnetotherapy: A New Weapon in Urinary Incontinence?

Objective: Urinary incontinence (UI) is one of the most common urinary system diseases that mostly affects women but also men. We evaluated the therapeutic efficacy of functional magnetic stimulation (FMS) as potential UI treatment with improvements in the pelvic floor musculature, urodynamic tests and quality of life. Methods: A total of 20 UI patients (10 females and 10 men, mean age 64, 14 years), including 10 with stress UI, four with urgency UI and six with mixed UI, were treated with FMS (20 min/session) twice a week for 3 weeks. The patients\u2019 impressions, records in urinary diaries, and scores of three life stress questionnaires (overactive bladder symptom questionnaire [OAB-q], urogenital distress inventory questionnaire-short form [UDI-6], incontinence impact questionnaire-short form [IIQ-7]) were performed pre- and post-treatment. Results: Significant reductions (P < 0.01) of micturition number and nocturia after magnetic treatment were evi- denced. The urodynamic tests recorded a significant increase in cystometric capacity (147 \ub1 51.3%), in maximum urethral closure pressure (110 \ub1 34%), in urethral functional length (99.8 \ub1 51.8%), and in pressure transmission ratio (147 \ub1 51.3%) values compared with the baseline values. Conclusions: These preliminary findings suggest that FMS with Magneto STYM (twice weekly for 3 weeks) improves the UI and may be an effective treatment for this urogenital disease

The impact of an environmental education program on third graders' knowledge, attitudes and behavioral intentions

The purpose of this study was to measure whether an after-school environmental education program based on modified Project Wild materials, positively impacted third graders environmental knowledge, attitudes and behavioral intentions. Eight lesson plans were developed, piloted and re-designed over a one year period and then delivered to third graders for a total of eight weeks in a fall semester. The lessons included units on water, air, land, recycling, insects, fish, amphibians, reptiles, birds and mammals. A pre-post test retrospective questionnaire was developed to determine changes in the participant's knowledge, attitudes and behavioral intentions as a result of participating in the program. Results indicate positive shifts in knowledge and changes in environmental attitudes and behavioral intentions. Recommendations were also made for future studies

STABILIZATION OF THE HYBRID IMMERSED BOUNDARY METHOD

The immersed boundary method is a model of fluid-structure interaction that uses a single momentum equation to account for the dynamics of a fluid and an immersed solid. The momentum equation is solved in Eulerian form, and fluid-solid coupling operators with delta function kernels are used to communicate between the Eulerian and Lagrangian frames. Over the years many extensions to the immersed boundary method have been introduced, notably the hyper-elastic extension of Boffi et al which treats the structure as a finite volume. Subsequent to this work, Griffith and Luo introduced a hybrid numerical approach to Boffi's formulation, which used finite differences to approximate the Eulerian equations and C^0 finite elements to solve the Lagrangian equations. This new numerical method presents both more flexibility and more challenges. Specifically, questions arise as to how to adequately maintain incompressibility of the solid in the Lagrangian frame, how to choose the discrete set of points that most efficiently couples the fluid and solid, and how to model finitely-thin structures. In this work we leverage techniques of computational mechanics to offer solutions to these questions.Doctor of Philosoph
