Negative Feedbacks On Bark Beetle Outbreaks: Widespread And Severe Spruce Beetle Infestation Restricts Subsequent Infestation, Sarah J. Hart, Thomas T. Veblen, Nathan Mietkiewicz, Dominik Kulakowski

Geography

Understanding disturbance interactions and their ecological consequences remains a major challenge for research on the response of forests to a changing climate. When, where, and how one disturbance may alter the severity, extent, or occurrence probability of a subsequent disturbance is encapsulated by the concept of linked disturbances. Here, we evaluated 1) how climate and forest habitat variables, including disturbance history, interact to drive 2000s spruce beetle (Dendroctonus rufipennis) infestation of Engelmann spruce (Picea engelmannii) across the Southern Rocky Mountains; and 2) how previous spruce beetle infestation affects subsequent infestation across the Flat Tops Wilderness in northwestern Colorado, which experienced …

Measuring Mental Health Provider Stigma: The Development Of A Valid And Reliable Self-Assessment Instrument, Jennifer L.K. Charles

Theses and Dissertations

Provider-based stigma is defined as the negative attitudes, beliefs, and behaviors of mental health providers toward clients they serve. Often unintentional and unknowingly conveyed, this phenomenon has been indicated in previous research (e.g. Lauber, Nordt, Braunschweig, & Rössler, 2006; Nordt, Rössler, & Lauber, 2006; Hugo, 2001; Schulze, 2007). Other instruments crafted to measure provider stigma have utilized theory in their development, without incorporating the voice of the client (e.g. Wilkins & Abell, 2010; Kennedy, Abell, & Mennicke 2014). To better address the social injustice posed by provider stigma, the profession requires a valid and reliable measure, guided by theory, which …

“Frailty, Thy Name Is Woman”: Depictions Of Female Madness, Julianna Little

Theses and Dissertations

Concepts of mental health and normality cannot be understood apart from cultural norms and values. The most significant of cultural constructions that shape our view of madness is gender. Madness has been perceived for centuries metaphorically and symbolically as a feminine illness and continues to be gendered into the twenty-first century. Works of art and literature and psychiatric medicine influence each other as well as our understanding and perception of mental illness. Throughout history, images of mental illness in women send the message that women are weak, dangerous, and require containment. What are the cultural links between femininity and insanity, …

Predicting Depression Symptoms Among College Students: The Influence Of Parenting Style, Sarah Whitmire Clark

Theses and Dissertations

This study examined parenting style variables in predicting college students’ depression symptoms. Participants were 989 college students who participated in the first wave of the Spit for Science project (Dick et al., 2011). This study described the prevalence of depression symptoms, including the percentage of the sample endorsing various depression symptoms, and the frequency depression scores were elevated at multiple time points. A hierarchical multiple regression was conducted to examine whether two dimensions of parenting style, Autonomy Granting and Parental Involvement, would interact in predicting depression symptoms in the Junior year. The present study demonstrates that parenting style predicts a …

Gender And Representative Bureaucracy: The Career Progression Of Women Managers In Male-Dominated Occupations In State Government, Velma J. Ballard

Theses and Dissertations

The tenets of representative bureaucracy suggest that the composition of the bureaucracy should mirror the people it serves including women in order to influence the name, scope, and implementation of public policies. Women are still underrepresented in mid-to-upper management in male-dominated occupations. When women are under-represented in mid-to-upper levels of management in government, there are implications regarding representative bureaucracy.

This study examined the career progression experiences of women who were successful in reaching mid-to-upper levels of management in male-dominated occupations in state government. Specifically, the study explored how women perceive various occupational factors including their rates of participation, experiences, gender, …

The Roles Of Gender And Ethnicity In College Student Bereavement, Rachel E. Weiskittle

Theses and Dissertations

The developmental stage of emerging adulthood often poses substantial challenges that negatively impact bereavement experiences (Schultz, 2007; Tanner & Arnett, 2009). Some emerging adults may be even more at risk for adverse grief outcomes due to individual differences such as gender and ethnicity, but very few studies have investigated these variables within the population. We addressed this gap in the literature by investigating the influence of gender and ethnicity on college students’ bereavement experiences using the Hogan Grief Reaction Checklist (HGRC; Hogan, Greenfield, & Schmidt, 2001) Results indicates a significant relationship between ethnicity and levels of personal growth, use of …

Heterosandwich Assay Of Nicotinic Acetylcholine Receptors, Augustine J. Pagan Iv

Theses and Dissertations

Using the technology afforded by Winschel et al., cyclen-1, a high affinity, strong complexation agent for 8-hydroxypyrene-1,3,6 trisulfonate and derivatives, a new assay has been developed for fluorescently labeling proteins of interest (POIs). Ligation of the endogenous ligand for nicotinic acetylcholine receptors (nAChRs), acetylcholine, using click chemistry afforded the triazole derivative of an alkynyl-acylcholine (compound 1) with 8-azidopyrene-1,3,6 trisulfonate (compound 2). Liposomes encapsulated with Rhodamine B were used to strengthen the initial fluorophore response of compound 2, using an anchored form of cyclen-1 complex. Using a palmitoyl tail as the lipophilic moiety for liposomal amplification, the …

Functional Characterization Of Rai1 In Zebrafish, Joshua S. Beach

Theses and Dissertations

Smith-Magenis Syndrome (SMS; OMIM #182290) is a multiple congenital abnormality and intellectual disability (ID) disorder caused by either an interstitial deletion of the 17p11.2 region containing the retinoic acid induced-1 (RAI1) gene or a mutation of the RAI1 gene. Individuals diagnosed with SMS typically present characteristics such as ID, self-injurious behavior, sleep disturbance, ocular and otolaryngological abnormalities, craniofacial and skeletal abnormalities, neurological and behavioral abnormalities, as well as other systemic defects and manifestations. Previous work by Vyas in 2009 showed temporal expression of rai1 in zebrafish embryos as early as 9 hpf. We hypothesize that there is maternal …

Reconnect: Designing To Touch, Dana Seros Rohani

Theses and Dissertations

Our everyday lives are surrounded by gadgets and digital devices that help us perform our daily chores with ease and efficiency. However, these digital devices can also separate us from what we should do ourselves. Although children who are exposed to high levels of technology might become attuned to the latest and the best gadgets, they might not learn to use their physical abilities. Another implication of a child’s over dependence on technology is that parental interactions such as encouragement, tutoring and reinforcement are provided by gadgets rather than living, breathing parents. Research done by Padma Ravichandran and Brandel France …

Risk As A Proxy For Race: The Dangers Of Risk Assessment, Bernard E. Harcourt

Faculty Scholarship

Actuarial risk assessment in the implementation and administration of criminal sentencing has a long history in this country – a long and fraught history. Today, many progressive advocates promote the use of actuarial risk assessment instruments as part of a strategy to reduce the problem of "mass incarceration." Former Attorney General Eric Holder has called on the U.S. Sentencing Commission to hold hearings to further consider the matter of risk assessment and prediction tools in sentencing and parole.

The objective – to reduce our massive over-incarceration in this country – is critical and noble. But risk assessment tools are simply …

Genetic Integrity Assessment Of Cryopreserved Tomato (Lycopersicon Esculentum Mill.) Genotypes, Ana Coste, Dana Suteu, Ioan Bacila, Constantin Deliu, Sergiu Valimareanu, Adela Halmagyi

Turkish Journal of Biology

Shoot tips of five tomato (Lycopersicon esculentum Mill.) genotypes were successfully cryopreserved by droplet vitrification. Recovered plants were studied for genetic stability by two different assays: amplified fragment length polymorphism (AFLP) using 4 primer combinations and sequencing of lycopene $\beta$-cyclase gene (LCY-B) from leaves. The highest shoot regeneration after cryopreservation was 70% (Pontica) following 24 h osmoprotection in 0.5 M sucrose and 30 min dehydration in plant vitrification solution 2 (PVS2). The data inferred from AFLP showed no genetic dissimilarities between in vitro regenerants derived from cryopreserved tissues compared with the noncryopreserved controls. Although a single nucleotide polymorphism, a G→T …

Expression Profiles Of Genes Related To Melatonin And Oxidative Stress In Human Renal Proximal Tubule Cells Treated With Antibiotic Amphotericin B And Its Modified Forms, Joanna Gola, Aleksandra Skubis, Bartosz Sikora, Celina Kruszniewska-Rajs, Jolanta Adamska, Urszula Mazurek, Barbara Strzalka-Mrozik, Grzegorz Czernel, Mariusz Gagos

Turkish Journal of Biology

Melatonin protects cells from oxidative stress caused by antibiotics. Through the generation of reactive oxygen species (ROS), amphotericin B (AmB) causes oxidative injuries of the kidneys and liver. Generation of oxidized forms of AmB (AmB-ox) in a patient's circulation may also generate ROS, causing side effects. Studies aimed at elimination of toxic properties of AmB are focused on forming complexes of AmB with copper(II) ions (AmB-Cu2+). However, the influence of such modified forms on renal cells and their transcriptome has not been studied so far. Therefore, the aim of this study was to answer the question of whether AmB-Cu2+ complexes …

The Administrative Conference And The Political Thumb, Peter L. Strauss

Faculty Scholarship

In his valuable contribution to this special issue, Richard Pierce underscores the role the Administrative Conference of the United States (“ACUS”) has played over the years in encouraging on the ground fact-finding by its consultants, who have usually been academics consulted at the beginning of careers that ever after would be marked by this encounter with the realities of the administrative process. As the mentee of Walter Gellhorn, who directed the remarkable empirical studies of federal agency procedures that underlay the eventual Administrative Procedure Act (“APA”) and who was a member of the ACUS Council from its initiation in 1964 …

Rethinking Jacob & Youngs V. Kent, Victor P. Goldberg

Faculty Scholarship

Most living lawyers have run into Jacob & Youngs, Inc. v. Kent in their legal education. It has long been a staple in Contracts casebooks. While the result has been widely applauded, in recent years there has been some push-back. Professor Kenneth Ching has recently criticized both Cardozo’s argument and the result. Professor Robert Scott in a number of papers, some coauthored, has also concluded that the result was wrong. Yet given the state of New York law at the time Cardozo’s result was correct. Moreover, I will argue, the outcome is one that parties would adopt today. Ironically, despite …

A Crib Sheet For Contracts Profs, Victor P. Goldberg

Faculty Scholarship

Over the last two decades I have been digging into the facts on a number of contracts cases, many of them featured in casebooks. I have collected the material in two books; one appeared in 2006 and the other is hot off the presses. This brief paper provides a roadmap for professors who might want more depth on the cases than is provided in the decisions or the casebooks. A recurring theme in the two books is that parties designing their contractual relationships must deal with change. This shows up in the manner in which they price the option to …

Flow Mechanisms And Numerical Simulation Of Gas Production From Shale Reservoirs, Chaohua Guo

Doctoral Dissertations

"Shale gas is one kind of the unconventional resources which is becoming an ever increasing component to secure the natural gas supply in U.S. Different from conventional hydrocarbon formations, shale gas reservoirs (SGRs) present numerous challenges to modeling and understanding due to complex pore structure, ultra-low permeability, and multiple transport mechanisms.

In this study, the deviation against conventional gas flow have been detected in the lab experiments for gas flow through nano membranes. Based on the experimental results, a new apparent permeability expression is proposed with considering viscous flow, Knudsen diffusion, and slip flow. The gas flow mechanisms of gas …

Small Sample Saddlepoint Confidence Intervals In Epidemiology, Pasan Manuranga Edirisinghe

Doctoral Dissertations

"In section 1, we develop a novel method of confidence interval construction for directly standardized rates. These intervals involve saddlepoint approximations to the intractable distribution of a weighted sum of Poisson random variables and the determination of hypothetical Poisson mean values for each of the age groups. Simulation studies show that, in terms of coverage probability and length, the saddlepoint confidence interval (SP) outperforms four competing confidence intervals obtained from the moment matching (M8), gamma-based (G1,G4) and ABC bootstrap (ABC) methods.

In section 2, we first consider Brillinger's classical model for a vital rate estimate with a random denominator. We …

Seismological Investigation Of The Okavango Rift, Botswana, Youqiang Yu

Doctoral Dissertations

The mechanisms of rifting have been intensively investigated using geological and geophysical techniques beneath mature rift zones. However, current understanding on the earliest stages of rifting is seriously limited. Here we employ recently archived data from 17 broadband seismic stations traversing northern Botswana to conduct the first shear wave splitting and mantle transition zone (MTZ) studies within the Okavango Rift Zone (ORZ). The ORZ is an incipient continental rift situated at the terminal of the southwestern branch of the East African Rift System. The resulting normal MTZ thickness and consistently rift-parallel fast polarizations imply an absence of significant thermal anomalies …

Model For Consolidation Analysis Of Layered Soils Under Depth-Dependent Loading, Hefu Pu, Patrick J. Fox

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A numerical model is presented for one-dimensional large strain consolidation of a layered soil stratum. The algorithm accounts for vertical strain, soil self-weight, conventional constitutive relationships, changing material properties during consolidation, unload/reload, time-dependent loading and boundary conditions, an externally applied hydraulic gradient, and multiple soil layers with different material properties. The model can also accommodate depth-dependent loading and variable preconsolidation stress profiles. Verification checks of the model show excellent agreement with available analytical and numerical solutions for consolidation of soils with multiple layers and depth-dependent loading. An overview of this model is presented, and a parametric study is performed to …

Dry Needling For Myofascial Trigger Point Pain: A Clinical Commentary, Casey Unverzagt, Kathleen Berglund, J J. Thomas

Faculty Publications

Sports and orthopaedic physical therapists have long used a multitude of techniques in order to address pain and dysfunction associated with myofascial trigger points. One technique in particular has recently received overwhelming attention: trigger point dry needling (DN). Despite its efficacy and low risk, questions remain as to its effectiveness, safety, and whether the technique is within the scope of practice of physical therapists. Therefore, the purpose of this clinical commentary is to summarize the current literature related to the associated mechanisms of action of DN, the safety of DN, as well as to discuss relevant scope of practice concerns.

Universal Computation With Arbitrary Polyomino Tiles In Non-Cooperative Self-Assembly, Sándor P. Fekete, Jacob Hendricks, Matthew J. Patitz, Trent A. Rogers

Computer Science Faculty Publications

In this paper we explore the power of geometry to overcome the limitations of non-cooperative self-assembly. We define a generalization of the abstract Tile Assembly Model (aTAM), such that a tile system consists of a collection of polyomino tiles, the Polyomino Tile Assembly Model (polyTAM), and investigate the computational powers of polyTAM systems at temperature 1, where attachment among tiles occurs without glue cooperation (i.e., without the enforcement that more than one tile already existing in an assembly must contribute to the binding of a new tile). Systems composed of the unit-square tiles of the aTAM at temperature 1 …

From The New Deal To The New Healthcare: A New Deal Perspective On King V. Burwell And The Crusade Against The Affordable Care Act, Sarah Helene Duggin

Scholarly Articles

Americans describe the new healthcare system established by the Patient Protection and Affordable Care Act (“ACA”) as both a blessing and a nightmare. For millions of low and middle income Americans, the ACA offers access to health insurance they could not otherwise afford. The ACA’s opponents, however, view the new healthcare system as a threat to economic prosperity, an intrusion on personal liberty and a violation of the principles of federalism at the heart of our system of government. These same kinds of arguments were made more than eighty years ago in response to President Franklin Delano Roosevelt’s New Deal. …

Existential Suffering And Cura Personalis: Dilemmas At The End-Of-Life, George P. Smith Ii

Scholarly Articles

Existential, or non-somatic suffering, is often associated with the management of refractory pain at the end-stage of life. Because of misleading sympathologies, this condition is often either mis-diagnosed or even ignored. When diagnosed as a part of a futile medical condition, this Paper argues that deep, palliative, or terminal sedation be offered to the distressed, dying patient as an efficacious and ethical response to preserving a semblance of human dignity in the dying process. Not only is this option of care humane and compassionate, it is consistent with the ideal of best patient care. The notion of care should not …
