Comparison Of Milling Cutting Forces In Synthetic And Biological Cancellous Bone, Matthew Christopher Hartwell

Masters Theses

In many orthopedic and dental interventions, the cutting and removal of bone is necessary. Therefore, it is of the utmost importance that the tools used during these procedures are designed and tested with biological bone or a bone surrogate material that machines the same way as biological bone. To avoid the cost, hazard, and inconsistency of biological cadaveric bone or animal models, many biological engineering firms use bone surrogate material made of glass fiber filled epoxy and polyurethane foam. Although these materials may mimic the elongation of cortical and cancellous bone, respectively, the match of machinability of the bone is …

The Role Of School-Based Law Enforcement Officers In Student Discipline, Marlaina Mahler

Walden Dissertations and Doctoral Studies

An increase in police presence in schools has led to an increase in research covering school police. The purpose of this qualitative study was to investigate the overall role of SBLE officers, specifically their role in student discipline. This narrative inquiry study answered two research questions about the narrative experiences of SBLE officers as law enforcers, educators, and mentors in Texas public schools and how might Texas SBLE officers’ lived experiences benefit their peers’ understanding of their role regarding student discipline. Role theory and role conflict theory were used as the theoretical foundation. Data were collected through interviews with ten …

Tar is an undesirable byproduct of biomass gasification, which can be removed through catalytic reforming to syngas components. Iron is a promising, abundant alternative to highly active but toxic nickel catalysts. The results observed so far in catalytic studies with iron have been mixed. In this paper, the decomposition of naphthalene, a representative model compound of tar, was studied on the catalytic Fe(110) surface using temperature-programmed desorption (TPD), sum frequency generation spectroscopy (SFG), and X-ray photoelectron spectroscopy (XPS). Napthalene adsorption, dehydrogenation and the formation of surface carbon were investigated, as well as the influence of oxygen. In comparison with previous …

Background: Acute pain management is critical in postoperative care, especially in vulnerable patient populations that may be unable to self-report pain levels effectively. Current methods of pain assessment often rely on subjective patient reports or behavioral pain observation tools, which can lead to inconsistencies in pain management. Multimodal pain assessment, integrating physiological and behavioral data, presents an opportunity to create more objective and accurate pain measurement systems. However, most previous work has focused on healthy subjects in controlled environments, with limited attention to real-world postoperative pain scenarios. This gap necessitates the development of robust, multimodal approaches capable of addressing the …

Photogalvanic Shift Currents In Bifeo3-Lafeo3 Superlattices, Francesco Delodovici, Charles Paillard

Physics Faculty Publications and Presentations

Designing materials with a controlled photovoltaic response may lead to improved solar cells or photosensors. In this regard, ferroelectric superlattices have emerged as a rich platform to engineer functional properties. In addition, ferroelectrics are naturally endowed with a bulk photovoltaic response stemming from nonthermalized photoexcited carriers, which can overcome the fundamental limits of current solar cells. Yet, their photovoltaic output has been limited by poor optical absorption and poor charge collection or photoexcited carrier mean free path. We use Density Functional Theory and Wannierization to compute the so-called Bulk Photovoltaic shift current and the optical properties of BiFeO3/LaFeO3 superlattices. We …

From Λ-Hollow Frames To Λ-Repletions In W: Ii. Λ-Repletions In W, Richard N. Ball, Anthony W. Hager, Joanne Walters-Wayland

Mathematics, Physics, and Computer Science Faculty Articles and Research

In this article we analyze the fine structure of the essential extensions of an object of W, the category of divisible archimedean lattice ordered groups with designated weak units. In particular, we show that an object Ghas an ordinally indexed sequence {τ^α_G}_δG of essential extensions with the following features. τ⁰_G is (isomorphic to) the identity function on G.

• For every α>0, τ^α_G is an essential extension of G into a W-object which is of the form RLfor some frame L, and which is λ-replete for some λ.

• Every such …

Browning Events In Arctic Ecosystems: Diverse Causes With Common Consequences, Scott Davidson

School of Geography, Earth and Environmental Sciences

Arctic ecosystems are experiencing extreme climatic, biotic and physical disturbance events that can cause substantial loss of plant biomass and productivity, sometimes at scales of >1000 km2. Collectively known as browning events, these are key contributors to the spatial and temporal complexity of Arctic greening and vegetation dynamics. If we are to properly understand the future of Arctic terrestrial ecosystems, their productivity, and their feedbacks to climate, understanding browning events is essential. Here we bring together understanding of browning events in Arctic ecosystems to compare their impacts and rates of recovery, and likely future changes in frequency and distribution. We …

Body Dysmorphia In Post-Weight Loss Surgery Patients, Theresa M. Niles

Walden Dissertations and Doctoral Studies

Although there is a known link between weight loss surgery and body dysmorphic disorder, research has not been conducted on the experiences of individuals experiencing these two phenomena. Using a phenomenological approach, this study examined the research question: What are the lived experiences of post-weight loss surgical patients with diagnosed body dysmorphia? Self-discrepancy theory was used as the overarching theoretical framework. Interviews were conducted with ten participants, and the data were analyzed using Quirkos software and inductive coding, examining clusters of themes within the narrative transcripts. Themes emerging included focusing on physical rather than mental health in the post operative …

A Qualitative Exploration Of The Milwaukee Chapter Of My Brother’S Keeper Community Challenge Program, Courtney Santanna Hayward

The purpose of this generic qualitative study was to explore administrators’ perspectives on whether the current funding resources of the MBK program in Milwaukee were adequate to ensure the program’s ability to meet its goal of increasing graduation rates and college readiness of its participants. Resource dependence theory and the teleological process theory guided the study. Braun and …

Assessing The Influence Of An Eastern State's Disciplinary Alternative Education Program On Secondary Student Behavior, Alicia Michelle Gallaway

Walden Dissertations and Doctoral Studies

Services at the local disciplinary alternative education program (DAEP) include counseling and behavioral services to referred secondary students, aiming to improve their behavior. The problem addressed in this quantitative study was that a DAEP was in place in the local district since 2009, but there had been no formal assessment to determine whether differences in student discipline occurred in the semester before and the semester after students attended the DAEP. Guided by Bandura’s social cognitive theory, the purpose of this ex post facto, causal-comparative, quasi-experimental study was to investigate if there was a difference in student discipline as measured by …

The Experience Of Help Seeking For African American Pastors In Personal Crises, Jason Leon Hanna

Walden Dissertations and Doctoral Studies

The U.S. population faces enormous challenges coping with disease, financial stress, failure, and general mental health concerns. Rather than seeking care from psychotherapists, increasing numbers of people in religious communities seek help from clergy, who must then balance the needs of their constituents while navigating their own personal crises and need for support. The purpose of this qualitative study was to explore the meaning of help-seeking for African American clergy during personal crises, guided by Ajzen’s theory of planned behavior. Semistructured interviews were conducted with 20 African American senior pastors of congregations in the United States. Study participants defined help-seeking …
