In The Wasteland Of Your Mind: Criminology, Scientific Discovieries And The Criminal Process, Michael L. Perlin, Alison Lynch

Articles & Chapters

This paper addresses a remarkably-underconsidered topic: the potential impact of scientific discoveries and an increased understanding of the biology of human behavior on sentencing decisions in the criminal justice system, specifically, the way that sentencing has the capacity to rely on scientific evidence (such as brain imaging) as a mitigating factor (or perhaps, in the mind of some, as an aggravating factor) in determining punishment.

Such a new method of evaluating criminality, we argue, can be beneficial not only for the defendant, but also for the attorneys and judge involved in the case. If used properly, it may help to …

Improved Sugar Yields From Biomass Sorghum Feedstocks: Comparing Low‑Lignin Mutants And Pretreatment Chemistries, Bruno Godin, Nick Nagle, Scott Satler, Richard Agneessens, Jérôme Delcarte, Edward Wolfrum

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Background: For biofuel production processes to be economically efficient, it is essential to maximize the production of monomeric carbohydrates from the structural carbohydrates of feedstocks. One strategy for maximizing carbohydrate production is to identify less recalcitrant feedstock cultivars by performing some type of experimental screening on a large and diverse set of candidate materials, or by identifying genetic modifications (random or directed mutations or transgenic plants) that provide decreased recalcitrance. Economic efficiency can also be increased using additional pretreatment processes such as deacetylation, which uses dilute NaOH to remove the acetyl groups of hemicellulose prior to dilute acid pretreatment. In …

Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke

Animal Sentience

Broom’s (2014) book is a well-researched and thoroughly written exploration and evaluation of the journey from the origins of animal welfare science to what we can say we now know and need to consider in relation to animal sentience and welfare. This book will help to counter any skepticism among academics and policy makers.

Predictability Of Delinquency Through Psychosocial And Environmental Variables Across Three Generational Status Groups, Margaret Frances Sabia

Walden Dissertations and Doctoral Studies

Issues such as the rapid growth of the immigrant youth population and delinquency among adolescents generate public safety concerns among the U.S. population. However, delinquency intervention strategies for immigrant youth in the United States remain scant, which is problematic because these youth face acculturative challenges that increase their risk for maladaptive outcomes. This quantitative, cross-sectional study addressed a research gap regarding the differential influence of risk factors in predicting delinquency across 3 generational statuses. The theoretical framework guiding the study consisted of acculturation theory, the immigrant paradox, and differential association theory. Two research questions were evaluated using a stratified random …

Experiences And Perceptions Regarding Emergency Telephone Number Use Relative To Civic Engagement, Jacquetta Mccoy

Walden Dissertations and Doctoral Studies

Lack of engagement in public service awareness education programs, coupled with reduced funding to implement a diversion system such as 311 systems or 10-digit phone numbers, contribute to 911 misuse. Many local governments have invested in alternative systems, but research regarding community members' use of 911 or alternatives relative to civic engagement is lacking. Guided by Gordon's conceptualization of civic engagement, this phenomenological study bridged the gap in knowledge by exploring community members' civic involvement and their use of 911 between 2012 and 2015 in a county in the state of Georgia. A snowball sampling strategy was used to select …

Enhancing Conservation Options: An Argument For Statutory Recognition Of Options To Purchase Conservation Easements (Opces), Federico Cheever, Jessica Owley

Journal Articles

The most dynamic component of the conservation movement in the United States for the past three decades has been land conservation transactions. In the United States, land conservation organizations have protected roughly 40 million acres of land through transactions. Most of these acres have been protected using conservation easements. Climate change threatens the vast conservation edifice created by land conservation transactions. The tools of land conservation transactions are, traditionally, stationary. Climate change means that the resources that land conservation transactions were intended to protect may no longer remain on the land protected. Options to purchase conservation easements (OPCEs) have long …

Is Assisted Procreation An Lgbt Right?, Michael Boucai

Journal Articles

A movement long identified with the notion that “love makes a family” today flirts dangerously with the dogma that “blood is thicker than water.” Biogeneticism, an ideology that favors biological modes of kinship and genetic conceptions of identity, informs many LGBT individuals’ choices about why and how to have children. In turn this ideology marks two troubling features of political efforts to facilitate LGBT parenthood: first, the markedly different understandings of equality — full versus formal, lived versus legal — that guide movement approaches to assisted procreation and adoption, respectively; and second, invocations of a fundamental “right to procreate” that …

Differentiating Deference, Anya Bernstein

Journal Articles

When an administrative agency’s interpretation of an ambiguous statutory term is challenged in court, the Chevron doctrine instructs judges to evaluate whether it is reasonable. But how does a court know reasonableness when it sees it? Here, I first show that reasonableness review is more complex than it might seem. Contrary to common images, for instance, courts do not determine a range of reasonable interpretations; and that is a good thing, because they are not competent to do so. Moreover, because traditional statutory interpretation approaches presume the existence of one correct meaning for a given word, they are not well …

Importance Of Soil And Plant Community Disturbance For Establishment Of Bromus Tectorum In The Intermountain West, Usa, A. Joshua Leffler

Natural Resource Management Faculty Publications

The annual grass Bromus tectorum has invaded millions of hectares in western North America and has transformed former perennial grass and shrub-dominated communities into annual grasslands. Fire plays a key role in the maintenance of B. tectorum on the landscape but the type of disturbance responsible for initial invasion is less well understood. We conducted an experiment in a perennial shrub/grass/forb community in eastern Idaho, USA to examine the roles of plant community and soil disturbance on B. tectorum emergence and establishment prior to state-changing fires. Our experiment consisted of a plant community disturbance treatment where we (1) removed the …

A Simple Method To Reduce Interpretation Error Of Ages Estimated From Otoliths, Bradley J. Smith, Daniel J. Dembkowski, Daniel A. James, Melissa R. Wuellner

Natural Resource Management Faculty Publications

We designed and tested a novel otolith viewing apparatus termed the otolith illumination device (OID) to ascertain if its use would result in a reduction of interpretation error as determined by increased precision of age estimates obtained from otoliths of walleye Sander vitreus and smallmouth bass Micropterus dolomieu. Clarity of annuli on otolith sections viewed with the OID was generally greater than clarity of annuli on sections viewed with an alternative method. OID-based age estimates were equally as, and in some instance more precise than ages estimated using the alternative method. Additionally, no systematic differences in coefficients of variation …

Seed Source May Determine Field-Specific Germination And Emergence: The Source By Planting Environment Interaction, Erin K. Espeland, Lora B. Perkins, Matthew E. Horning, Richard C. Johnson

Natural Resource Management Faculty Publications

Farm environmental conditions and management practices can result in within-cultivar differences in seed quality and lead to transgenerational plasticity (farm-specific effects on offspring, or TGP) that affect germination and emergence in transplant fields. We used three perennial bunchgrasses, [green needlegrass (Nassella viridula) ‘Lodorm’, slender wheatgrass (Elymus trachycaulus) ‘Pryor’, and bluebunch wheatgrass (Pseudoregneria spicata) prevariety registered germplasm P-7] to determine if seeds exhibited TGP. We also determined if TGP was affected by the interaction between production farms and planting environments (farm × environment interaction, or context-dependent TGP), using four laboratory temperature regimes to test germination response and four field environments to …

Winter Habitat Quality But Not Long- Distance Dispersal Influences Apparent Reproductive Success In A Migratory Bird, Clark S. Rushing, Peter P. Marra, Michele R. Dudash

Natural Resource Management Faculty Publications

Long- distance breeding and natal dispersal play central roles in many ecological and evolutionary processes, including gene flow, population dynamics, range expansion, and individual responses to fluctuating biotic and abiotic conditions. However, the relative contribution of long- distance dispersal to these processes depends on the ability of dispersing individuals to successfully reproduce in their new environment. Unfortunately, due to the difficulties associated with tracking dispersal in the field, relatively little is known about its reproductive consequences. Furthermore, because reproductive success is influenced by a variety of processes, disentangling the influence of each of these processes is critical to understanding the …

Determining The Barriers To And Opportunities For Community Involvement In The Management Of The Nanda Devi Biosphere Reserve, Uttarakhand, India, Trisha Singh

Graduate Student Theses, Dissertations, & Professional Papers

Today’s global political environment places a high value on social equality and economic well- being. In this climate, emphasizing biodiversity conservation over socio-economic development through exclusionary methods of habitat protection has become ethically questioned and politically dangerous. The goal of this research was to understand the barriers and opportunities for local involvement in the management of the Nanda Devi Biosphere Reserve in Uttarakhand, India. We attempted to understand the feasibility of local community involvement in the management of the NDBR from the perspective of policy-making organizations and that of the local communities.

Key findings highlight barriers to community participation at …

Close Call With Nonexistence: A Memoir, Jeff Gailus

Graduate Student Theses, Dissertations, & Professional Papers

Fred Eduard Gailus was born on April 26, 1944, in Memelland, a place that no longer exists. It was a tiny sliver of Germandom on the far eastern edge of Hitler’s outsized German Reich. When the Soviet Red Army swept through on their way to Berlin, to end World War Two and the reign of terror perpetrated by the German people, the homeland of my father’s ancestors was wiped off the map forever. Thanks to the courage and tenacity of his mother, Fred survived the largest forced migration in human history to marry young and raise a family of four …

Conservation Genetics On The Frontline, Kenneth W. Rand

Graduate Student Theses, Dissertations, & Professional Papers

Conservation genetics stands out as an effective tool for discovering and monitoring rare, endangered or invasive populations of plants and animals. Particularly when compared to traditional search and capture methods, it provides more holistic studies to preserve the disappearing biodiversity of the American West and the world.

Three stories highlight the work done to preserve biodiversity through the use of conservation genetics:

1. Trout Rescue: A new hope for westslope cutthroat in Montana How to save a disappearing westslope cutthroat trout through genetic rescue by adding genetic diversity to ensuring future survival in increasingly warming waters more harm than good. …

Spatio-Temporal Analysis Of Ungulate Browsing On Willow (Salix Spp.) Communities Within The Northern Range Of Yellowstone, Donald L. Belile Jr.

Graduate Student Theses, Dissertations, & Professional Papers

Variation in ungulate browsing intensity on willow (Salix spp.) communities across Yellowstone’s northern range has been attributed to various biophysical factors including climate, topography, and predators. These studies were conducted without a long-term browsing dataset; they lacked a spatially extensive sampling design, and did not include dynamic snow characteristics known to affect ungulate mobility, habitat selection, and foraging strategies. We therefore focused on snow, an extreme landscape level disturbance that places nutritional stress on ungulates during the winter when most browsing on shrubs occurs. We applied a non-destructive sampling method by consecutively recording whether stem leaders were browsed between …

Human Shields And Redistribution Of Prey Species Complicate The Utility Of Protected Areas As Ecological Baselines, Wesley Sarmento

Graduate Student Theses, Dissertations, & Professional Papers

A key goal of protected areas is the conservation of biodiversity, an aim that garners increasing public support through positive experiences. Increasing visitation, however, can come at the cost of reduced ecological integrity. A fundamental conundrum is that if parks are to serve as our most pristine places, then we must understand how our presence alters species interactions. Species redistributing closer to people is of growing management concern both in and out of national parks because of 1) human safety, 2) animal health, and 3) ecological consequences. Across parks drivers of distributional change are often dissimilar, and include movement to …

Cyber-Victimization And Delinquency: A General Strain Perspective, Ian D. Greenwood

Graduate Student Theses, Dissertations, & Professional Papers

This study examines juvenile delinquency and cyber-victimization from a general strain perspective. General strain theory provides a model where strain is experienced through the (1) loss of something valued, (2) the presentation of noxious stimuli, or (3) the inability to achieve valued goals. As a coping mechanism for strain, some juveniles react through criminal or delinquent behavior. This thesis predicts that cyber-victimization increases the likelihood of physical fighting, weapon-carrying, and truancy at school. Using the 2013 National Crime Victimization Survey: School Crime Supplement, the hypotheses are analyzed using multivariate logistic regression models that include other known correlates of delinquency. Marginal …

An Evaluation Of The Effectiveness Of Eukaryotic Dna Extraction From Burial Soil Samples, Ariane Thomas

Graduate Student Theses, Dissertations, & Professional Papers

DNA is a valuable resource as a unique identifier of physical characteristics at both the population and individual levels. Due to a variety of factors that contribute to genetic decay, forensic and bioarchaeological investigators have limited outlets in which to extract viable DNA after most of a body’s organic materials have fully decomposed. This preliminary research focused on extracting DNA from the soil surrounding buried Sus scrofa domesticus cadavers to confirm the presence of viable and analyzable DNA. After a decomposition period of five months in Montana, soils were collected at incremental distances above the remains and sequenced to identify …

Ecology Of The Alluvial Aquifer Of The Nyack Floodplain On The Middle Fork Of The Flathead River, Montana, Amanda Gay Delvecchia

Graduate Student Theses, Dissertations, & Professional Papers

The pristine Nyack Floodplain on the Middle Fork of the Flathead River in Northwestern Montana contains an expansive alluvial aquifer that is extremely limited in organic carbon, yet supports abundant and diverse hyporheic stoneflies. My dissertation focused broadly on how these large consumers persist in such an oligotrophic system. In particular, I studied the ecological role of methane dynamics.

Confidence Judgments In A Simultaneous Task Using Sprague Dawley Rats (Rattus Norvegicus), Jessica K. Kumm

Graduate Student Theses, Dissertations, & Professional Papers

In the present experiment, metacognitive confidence judgments were measured in the Sprague-dawley rats using a simultaneous discrimination task. Performance on two types of trials were compared: Forced and Choice. For Forced trials, subjects were required to classify a range of eight tones as either a “long” or “short” tone with the four longest frequency durations comprising the “long” tone category and the four shortest frequency tones comprising the “short” tone duration category. The Choice trials were identical to the Forced trials with the exception that a bailout response was also available, allowing the subject to advance to the next trial …

A Comparison Of Course Quality Surveiy Results From Students On Gender Balanced And Gender Imbalanced Field Courses At Nols, Alexandra M. Alway

Graduate Student Theses, Dissertations, & Professional Papers

There is an extensive database of literature about diversity in outdoor Environmental Education and any of the studies focus on NOLS specifically. Several studies have investigated the impact of course composition in terms of gender as well as socioeconomic diversity; however, the research studies about course composition and gender were limited to differences between single gender and coed groups. The role of gender ratios on coed groups has not been widely researched. This study was designed to fill this gap in the research literature. Using course quality survey data, results showed that the student responses were significantly different between gender …

Polymer Nanoparticles In Electrokinetic Chromatography, Jesse Samuel Hyslop

Graduate Student Theses, Dissertations, & Professional Papers

Electrokinetic chromatography (EKC) is a prevalent analytical separation technique first introduced by Terabe et al. in 1984. EKC is a modification of capillary electrophoresis in which analytes are separated via selective interactions between analytes and an ionic pseudostationary phase (PSP) dispersed in the background electrolyte (BGE) buffer which fills the capillary. Application of an electric field of several hundred volts per cm on the capillary induces electroosmotic flow (EOF) of the BGE and mobility of the PSP. Various ionic PSPs are capable of fast, selective, and efficient analytical separations.

Extreme Hybrid Growth, Genomic Imprinting, The Large X Effect, And The Drivers Of Speciation In Mammals, Thomas David Brekke

Graduate Student Theses, Dissertations, & Professional Papers

Mammalian hybrids often show abnormal growth, indicating that developmental inviability may play an important role in mammalian speciation. Yet it is unclear if this recurrent phenotype reflects a common genetic basis. Here I describe patterns of hybrid inviability between two closely related species of dwarf hamsters, Phodopus campbelli and P. sungorus. Using genetic crosses, I found extreme parent-of-origin dependent growth in hybrid embryos and placentas. Abnormal growth in hybrid mammals has been empirically linked to genomic imprinting, the parent-specific silencing of a single allele that occurs in many genes involved in regulating embryonic growth. Epigenetic disruptions of genomic imprinting activate …

School Supports For Lgbtq Students: Counteracting The Dangers Of The Closet, Lauri Mae Lindquist

Graduate Student Theses, Dissertations, & Professional Papers

Researchers have reported that being proud and open about one’s sexual and/or gender identity is related to fewer negative psychological outcomes. However, this process of identity development is often impeded by environmental factors, such as minority stress. Through his minority stress hypothesis, Meyer (2003) suggests that suggests that living in a society that is intolerant of central features of the self (e.g., sexual orientation and gender identity) increases the level of stress in individuals with minority statuses. These environmental stressors are consistently shown by research to account for the disproportionate amount of negative psychological and academic outcomes experienced by sexual …

Impact Of A Diesel Spill On Macroinvertebrate Communities In Ponds In S.E. Alabama, Usa, Katie E. Winkles

Theses and Dissertations

In this study, macroinvertebrate communities were examined to determine an indication of the water quality in ponds on a wetlands property after a diesel spill. In 2012, a train derailed, and at least 3000 gallons of diesel fuel leached into a small pond of the wetlands. Even after clean-up attempts there remains major concerns that the contamination spread throughout the wetlands. This concern led to the present study. Macroinvertebrates were the chosen focus due to their sensitivity to changes in the environment. Two field trials were conducted in which Hester-Dendy multiplate samplers were placed in ponds to allow macroinvertebrates to …
