A Comparison Of Strain, Social Learning, Control, And Trauma Theories Of Crime, Nicole Trauffer

Dissertations, Theses, and Capstone Projects

The field of criminology has been dominated by Strain, Control and Social Learning Theories, among others. More recently, research and theory has focused on the role of trauma as a predictor of criminal behavior, especially for women. However, little research has empirically compared these theories to one another. The current study examined these four major theories to determine which best explains non-violent and violent criminal behaviors. Race and sex differences were examined. The data is from a large prospective cohort design study of individuals with documented histories of physical and sexual abuse and neglect and a control group of children …

I. Selective Chlorination And Fluorination Of Quinols Ii. Synthetic Study Of Strongylophorine-26, Sihan Li

Dissertations, Theses, and Capstone Projects

Organic compounds containing halogen are an important and useful class of intermediates that can be converted to other functionalities. This thesis describes our strategy in selective chlorination and fluorination of quinols to offer the corresponding aromatic structures. Quinols, or cyclohexadienones, as oxidized derivatives of phenols, have their remarkable chemical reactivities, including additions to enone, enolate alkylations, aldol reactions, cycloadditions, and rearrangements. Dienone-phenol rearrangement provides the asymmetric route since the stereocenters located in the six-membered ring of various cyclohexadienone were widely using in building larger chiral arrays for many total syntheses

Chapter one of this thesis discusses our new selective nucleophilic …

Stalking And Attachment Theory: Causes And Management, Zoe Turner

Dissertations, Theses, and Capstone Projects

Stalking is an issue that has drawn increasing attention over the past four decades. Approximately 6 million Americans report being the victims of stalking each year. The psychological and physical effects of stalking can be severe, ranging from anxiety and depression to physical harm and even death. With the rise of technology and social media, cyberstalking has become an additional problem in recent years. It is vital to understand the root causes of stalking behavior from a psychological perspective in order to create appropriate management and treatment plans. The current research investigates the role of attachment theory in stalking. Within …

Dietary Development And Nutritional Ontogeny In Gorilla Beringei : A Multi-Layered, -Omics Approach, Emma C. Cancelliere

Dissertations, Theses, and Capstone Projects

In species who consume folivorous diets, immature individuals must contend with the challenges of extracting nutrients from fibrous foods before dietary adaptations and strategies are fully developed. Additionally, immatures have distinct nutritional needs to support their stage-specific metabolic and biophysiological requirements. To meet these stage-specific needs, while constrained by underdeveloped feeding strategies and digestive capacities, immatures may adopt distinct diets better suited to their specific developmental context. However, where dietary modification is constrained by low dietary diversity or landscape homogeneity, it is unclear how immature individuals compensate through alternative strategies. In turn, little is known about the nutritional and life …

Recognition Of An Α-Helical Hairpin In P22 Large Terminase By A Synthetic Antibody Fragment., Ravi K Lokareddy, Ying Hui Ko, Nathaniel Hong, Steven G Doll, Marcin Paduch, Michael Niederweis, Anthony A Kossiakoff, Gino Cingolani

Department of Biochemistry and Molecular Biology Faculty Papers

The genome-packaging motor of tailed bacteriophages and herpesviruses is a multisubunit protein complex formed by several copies of a large (TerL) and a small (TerS) terminase subunit. The motor assembles transiently at the portal protein vertex of an empty precursor capsid to power the energy-dependent packaging of viral DNA. Both the ATPase and nuclease activities associated with genome packaging reside in TerL. Structural studies of TerL from bacteriophage P22 have been hindered by the conformational flexibility of this enzyme and its susceptibility to proteolysis. Here, an unbiased, synthetic phage-display Fab library was screened and a panel of high-affinity Fabs against …

The Youngest Victims: Children And Youth Affected By War, James Garbarino, Amy E. Governale, Danielle Nesi

Psychology: Faculty Publications and Other Works

In 1989, the United Nation Convention on the Rights of the Child declared, “[state parties] shall take all feasible measures to ensure protection and care of children who are affected by an armed conflict.” In addition to attempting to secure the welfare of children in armed conflict, the Convention went on to ban the recruitment and deployment of children during armed conflict. Despite the vast majority of sovereign nations signing and ratifying this agreement, this treaty, unfortunately, has not prevented children and youth from witnessing, becoming victims of, or participating in political, ethnic, religious, and cultural violence across the past …

All Peer-Reviewed Publications

The use of black soldier fly frass fertilizer (BSFFF) is being promoted globally. However, information on nitrogen (N) fertilizer equivalence (NFE) value and synchrony of N mineralization for crop production remains largely unknown. Comparative studies between BSFFF and commercial organic fertilizer (SAFI) were undertaken under field conditions to determine synchrony of N release for maize uptake. The BSFFF, SAFI, and urea fertilizers were applied at the rates of 0, 30, 60, and 100 kg N ha−1. The yield data from urea treated plots were used to determine the NFE of both organic inputs. Results showed that maize from BSFFF treated …

Schizophrenia (SCZ) is a severe psychiatric disorder with a strong genetic component. High heritability of SCZ suggests a major role for transmitted genetic variants. Furthermore, SCZ is also associated with a marked reduction in fecundity, leading to the hypothesis that alleles with large effects on risk might often occur de novo. In this study, we conducted whole-genome sequencing for 23 families from two cohorts with unaffected siblings and parents. Two nonsense de novo mutations (DNMs) in GJC1 and HIST1H2AD were identified in SCZ patients. Ten genes (DPYSL2, NBPF1, SDK1, ZNF595, ZNF718, GCNT2, SNX9, AACS, KCNQ1, and MSI2) were found to …

Mtor-Initiated Metabolic Switch And Degeneration In The Retinal Pigment Epithelium, Young-Mi Go, Jing Zhang, Jolyn Fernandes, Christopher Litwin, Rui Chen, Theodore G Wensel, Dean P Jones, Jiyang Cai, Yan Chen

Faculty, Staff and Students Publications

The retinal pigment epithelium (RPE) is a particularly vulnerable tissue to age-dependent degeneration. Over the life span, the RPE develops an expanded endo-lysosomal compartment to maintain the high efficiency of phagocytosis and degradation of photoreceptor outer segments (POS) necessary for photoreceptor survival. As the assembly and activation of the mechanistic target of rapamycin complex 1 (mTORC1) occur on the lysosome surface, increased lysosome mass with aging leads to higher mTORC1 activity. The functional consequences of hyperactive mTORC1 in the RPE are unclear. In the current study, we used integrated high-resolution metabolomic and genomic approaches to examine mice with RPE-specific deletion …

Yttrium-90 Selective Internal Radiotherapy As Bridge To Curative Hepatectomy For Recurrent Malignant Solid Pseudopapillary Neoplasm Of Pancreas: Case Report And Review Of Literature, Adam R Dyas, David Thor Johnson, Erin Rubin, Richard D Schulick, Piyush Kumar Sharma

Faculty, Staff and Student Publications

Recurrent malignant solid pseudopapillary neoplasms of the pancreas (SPNP) are rare tumors with unpredictable clinical and histopathological features. There is a lack of consensus regarding utilization of adjuvant modalities in conjunction with or in lieu of curative metastatectomy. We present a remarkable case where Yttrium-90 selective internal radiation therapy (Y-90 SIRT) was successfully utilized to elucidate underlying tumor biology and aid resection of a large multifocal recurrent metastatic SPNP in the right hemi-liver of a 59-year-old female. Thus, in cases where curative metastatectomy remains the treatment goal in management of recurrent and/or metastatic SPNPs, Y-90 SIRT is a safe and …

Detection Of Software Vulnerability Communication In Expert Social Media Channels: A Data-Driven Approach, Andrei Lima Queiroz

Doctoral

Conceptually, a vulnerability is: "A flaw or weakness in a system’s design, implementation,or operation and management that could be exploited to violate the system’s security policy".Some of these flaws can go undetected and exploited for long periods of time after soft-ware release. Although some software providers are making efforts to avoid this situ-ation, inevitability, users are still exposed to vulnerabilities that allow criminal hackersto take advantage. These vulnerabilities are constantly discussed in specialised forumson social media. Therefore, from a cyber security standpoint, the information found inthese places can be used for countermeasures actions against malicious exploitation ofsoftware. However, manual inspection …

Loss Of Uncoupling Protein 3 Attenuates Western Diet-Induced Obesity, Systemic Inflammation, And Insulin Resistance In Rats, Tyler M Lomax, Sadia Ashraf, Gizem Yilmaz, Romain Harmancey

Faculty, Staff and Student Publications

OBJECTIVE: Uncoupling protein 3 (UCP3) is a mitochondrial carrier related to fatty acid metabolism. Although gene variants of UCP3 are associated with human obesity, their contribution to increased adiposity remains unclear. This study investigated the impact that loss of UCP3 has on diet-induced obesity in rats.

METHODS: Male UCP3 knockout rats (ucp3

RESULTS: Loss of UCP3 decreased fat mass gain, white adipocytes size, and systemic inflammation. The ucp3

CONCLUSIONS: Loss of UCP3 partially protects rats from diet-induced obesity. This phenotype is related to induction of a compensatory antioxidant mechanism and prevention of iBAT whitening.

Greening Of Grey Infrastructure Should Not Be Used As A Trojan Horse To Facilitate Coastal Development, Louise B. Firth, Laura Airoldi, Fabio Bulleri, Steve Challinor, Su Yin Chee, Ally J. Evans, Mick E. Hanley, Antony M. Knights, Kathryn O'Shaughnessy, Richard C. Thompson, Stephen J. Hawkins

School of Biological and Marine Sciences

Climate change and coastal urbanization are driving the replacement of natural habitats with artificial structures and reclaimed land globally. These novel habitats are often poor surrogates for natural habitats. The application of integrated greening of grey infrastructure (IGGI) to artificial shorelines demonstrates how multifunctional structures can provide biodiversity benefits whilst simultaneously serving their primary engineering function. IGGI is being embraced globally, despite many knowledge gaps and limitations. It is a management tool to compensate anthropogenic impacts as part of the Mitigation Hierarchy. There is considerable scope for misuse and ‘greenwashing’ however, by making new developments appear more acceptable, thus facilitating …

Sea-Ice Production And Air/Ice/Ocean/Biogeochemistry Interactions In The Ross Sea During The Pipers 2017 Autumn Field Campaign, S. F. Ackley, S. Stammerjohn, T. Maksym, M. Smith, J. Cassano, P. Guest, J.-L. Tison, B. Delille, B. Loose, Peter N. Sedwick, L. Depace, L. Roach, J. Parno

OES Faculty Publications

The Ross Sea is known for showing the greatest sea-ice increase, as observed globally, particularly from 1979 to 2015. However, corresponding changes in sea-ice thickness and production in the Ross Sea are not known, nor how these changes have impacted water masses, carbon fluxes, biogeochemical processes and availability of micronutrients. The PIPERS project sought to address these questions during an autumn ship campaign in 2017 and two spring airborne campaigns in 2016 and 2017. PIPERS used a multidisciplinary approach of manned and autonomous platforms to study the coupled air/ice/ocean/biogeochemical interactions during autumn and related those to spring conditions. Unexpectedly, the …

Case Report Of Ablative Magnetic Resonance-Guided Stereotactic Body Radiation Therapy For Oligometastatic Mesenteric Lymph Nodes From Bladder Cancer, Michael Chuong, Diane Alvarez, Tino Romaguera, Kathryn Mittauer, Sonia Adamson, Alonso Gutierrez, Gustavo Luciani, Hayden Guerrero Olmo, Antonio Ucar

All Publications

Several randomized trials have demonstrated that stereotactic body radiation therapy (SBRT) can significantly improve long-term clinical outcomes for patients with oligometastatic (OM) cancer, commonly defined as 1–5 metastatic lesions. Some lesions, especially those in the abdomen and pelvis, may not be appropriate candidates for receiving ablative dose if daily on-board computed tomography (CT) is used because of limited target lesion and normal anatomy visualization. Magnetic resonance imaging (MRI) inherently provides superior soft tissue delineation as compared to CT and only recently have MR-guided linear accelerators (LINACs) become commercially available. MR-LINACs can also perform daily online adaptive replanning based on the …

For Whom, And For What, Is Experience Sampling More Accurate Than Retrospective Report?, William D. Ellison, Alec C. Trahan, Joseph C. Pinzon, Megan E. Gillespie, Logan M. Simmons, Kendel Y. King

Psychology Faculty Research

The experience sampling method (ESM) is often used in research, and promoted for clinical use, with the rationale that it avoids problematic inaccuracies and biases that attend retrospective measures of mental phenomena. Research suggests that averaged scores from ESM data are more accurate than retrospective ratings. However, it is not known how well individuals can remember information about momentary (rather than averaged) mental states, nor how accurately they estimate the dynamic covariation of these states. Individual differences in retrospective accuracy are also poorly understood. In two pre-registered studies, we examined differences between retrospective memory for stress and self-esteem and data …

Investigation Of Undocumented Heart Disease In Cadaveric Donors, Crystal Danae Passburg

Doctoral Dissertations and Projects

For nearly a century, heart disease has been the leading source of death and disease in the United States, causing the deaths of hundreds of thousands of individuals every year and burdening millions more with diminished health and severe disability. However, despite the significant known prevalence of heart disease, studies suggest that many more individuals—and particularly those within the female and elderly populations—may possess undiagnosed heart disease which remains undetected even after death due to the lack of autopsy examination. In the absence of autopsy, many cases of heart disease may never be identified, resulting in a skewed understanding of …
