Human Origins, Dispersal And Associated Environments: An African Perspective, Amanuel Beyin

Faculty and Staff Scholarship

Africa’s position as the cradle of humanity is widely accepted, supported by rich fossil and archaeological discoveries from different parts of the continent. Drawing on the Out-of-Africa theory of human origins, this article provides a condensed narrative of the major milestones in human evolution and associated environmental settings. The underlying hypothesis is that changes in global climate played an important role in fueling early modern human origins and dispersals within and outside of Africa. As one will discover in this article, the history of humanity is a tale of small events that merged together into major milestones over a long …

Long-Term Characterization Of The Chronic Dopamine Microelectrode And Effect Of Electrical Conditioning, Eric P. Marr

EWU Masters Thesis Collection

Background: Dopamine (DA) is a neurotransmitter involved in movement, reward learning and addiction. Fast-scan cyclic voltammetry (FSCV) has long been an indispensable tool for monitoring real-time DA signaling. Development of polyimide fused silica-encased FSCV microelectrodes have made the technique more suitable for chronic DA monitoring (months) in vivo. Methods: In this study, electrically stimulated DA signals were evoked weekly in an effort to characterize the recovery time and stability of DA signals recorded long-term with silica-encased chronic DA microelectrodes. Additionally, electrical conditioning (etching), previously shown to improve microelectrode sensitivity in vitro, was performed to investigate the long-term impact on DA …

The Relationships Among Situational Leadershipâ® Ii, Emotional Intelligence And Discâ® Behavior, Margaretta Underhill

EWU Masters Thesis Collection

"What makes an effective leader? This question is often asked and while the specific ingredients of effective leadership may be hard to identify, the absence of effective leadership can be painfully clear. Many problems facing professionals, administrators and global leaders, indeed, those who lead in any situation, could be solved through more effective leadership strategies. The purpose of this quantitative study was to examine the relationships among the theory of Situational Leadership ® II, the DiSC® theory of behavioral dimensions and the Salovey & Mayer 1990 construct of emotional intelligence (Blanchard, P. Zigarmi, & D. Zigarmi, 1985; Inscape Publishing,1996; Salovey, …

Smallmouth Bass Abundance And Diet Composition In The Upper Spokane River, Michael Taylor Mccroskey

EWU Masters Thesis Collection

"I conducted a three month study, between June and August, in 2015 of Redband Trout (Oncorhynchus mykiss var. gairdneri) and Smallmouth Bass (Micropterus dolomieu) in the upper Spokane River in Washington, from the border between Washington and Idaho (rkm 154.5) to Harvard Road (rkm 149.2). The primary goals of the project were to: (1) determine the abundance and density of Redband Trout and Smallmouth Bass in the Starr Road area, as well as two reference sites, prior to possible habitat manipulation, (2) estimate the Smallmouth Bass population and density between the Washington/Idaho Stateline and Harvard Road, and (3) determine the …

Stream Microbial Communities Along An Agricultural Gradient, Cristine Mcintyre Schucker

EWU Masters Thesis Collection

"Although sediment microbes play key roles in decomposition and nitrogen (N) cycling, responses of microbial communities to N additions within watersheds is not well understood. Agriculture contributes excess N into stream systems, predominantly as ammonia, which is transformed through nitrification into nitrate by prokaryotes that produce the ammonia monooxygenase enzyme (AMO). The Latah Creek watershed in WA State (USA) drains approximately 1178 km², of which half is agricultural. Because the tributary streams reside in forested, agricultural and mixed use drainages, samples from these stream sediments capture microbial communities at different spatial gradients of land use. My research aimed to answer: …

Molecular Approaches For Improving Desiccation Tolerance : Insights From The Brine Shrimp Artemia Franciscana., Steven Hand, Michael Menze

Faculty and Staff Scholarship

Main conclusion We have evaluated the endogenous expression and molecular properties of selected Group 3 LEA proteins from Artemia franciscana , and the capacity of selected Groups 1 and 3 proteins transfected into various desiccation-sensitive cell lines to improve tolerance to drying. Organisms inhabiting both aquatic and terrestrial ecosystems frequently are confronted with the problem of water loss for multiple reasons—exposure to hypersalinity, evaporative water loss, and restriction of intracellular water due to freezing of extracellular fluids. Seasonal desiccation can become severe and lead to the production of tolerant propagules and entry into the state of anhydrobiosis at various stages …

Do Depressive Symptoms Predict The Incidence Of Myocardial Infarction Independent Of Hopelessness?, Patrick Pössel, Amanda M. Mitchell, Kimmo Ronkainen, George A. Kaplan, Jussi Kauhanen, Maarit Valtonen

Faculty and Staff Scholarship

Depression and hopelessness predict myocardial infarction (MI), but it is unclear whether depression and hopelessness are independent predictors of MI incidents. Hopelessness, depression, and MI incidence rate 18 years later were measured in 2005 men. Cox regressions were conducted with hopelessness and depression serving as individual predictors of MI. Another Cox model examined whether the two predictors predict MI when adjusting for each other. Depression and hopelessness predicted MI in independent regressions but when adjusting for each other, hopelessness, but not depression, predicted MI incidents. Thus, these results suggest that depression and hopelessness are not independent predictors of MI.

Integrating Beck’S Cognitive Model And The Response Style Theory In An Adolescent Sample., Stephanie Winkeljohn Black, Patrick Pössel

Faculty and Staff Scholarship

Depression becomes more prevalent as individuals progress from childhood to adulthood. Thus, empirically supported and popular cognitive vulnerability theories to explain depression in adulthood have begun to be tested in younger age groups, particularly adolescence, a time of significant cognitive development. Beck’s cognitive theory and the response style theory are well known, empirically supported theories of depression. The current, two-wave longitudinal study (N = 462; mean age = 16.01 years; SD = 0.69; 63.9 % female) tested various proposed integrative models of Beck’s cognitive theory and the response style theory, as well as the original theories themselves, to determine if …

Faculty Scholarship

As an introduction to a special issue on intellectual property philosophy, this article focuses on insights from Asian thought. Such a focus is needed not only to provide balance within this special issue, which includes articles focusing primarily on Western philosophy, but also to highlight the compatibility between Asian philosophy and the notion of intellectual property rights. More importantly, this article aims to demonstrate that Asian philosophy may suggest new ways to address the ongoing and highly complex intellectual property challenges confronting emerging economies and the digital environment.

This article begins by providing a brief discussion of the many different …

Adamts-4 And Adamts-5 Expression In Human Temporomandibular Joint Discs With Internal Derangement, Correlates With Degeneration, Rosalia Leonardi, Salvatore Crimi, Luis Eduardo Almeida, Giuseppe Pannone, Giuseppe Musumeci, Sergio Castorina, Mugurel Constantin Rusu, Carla Loreto

School of Dentistry Faculty Research and Publications

Temporomandibular joint (TMJ) internal derangement (ID) is one of the most common form of temporomandibular disorders. There is evidence showing the increased expression of matrix metalloproteinases (MMPs) in the cells from degenerated TMJ disc. ADAMTS are a large family of metalloproteases which are responsible for proteoglycans degradation. The present study aimed to evaluate ADAMTS-4 and ADAMTS-5 immunohistochemical expression in human TMJ discs from patients affected by ID, and to find out if there is any correlation with the degree of histopathological changes. Eighteen temporomandibular displaced disc specimens and sixteen TMJ disc control were used for the present study. Specimens were …

Exploring The Meaning Of Cohabitation: A Relationship Dialectics Perspective, Lindsey J. Thomas, Kristina M. Scharp

Iowa Journal of Communication

This study employed relational dialectics theory to investigate what cohabitation means to cohabiters. Cohabitation is an ambiguous relationship state (e.g., perceived as "more than dating" but "less than marriage") associated with negative outcomes. Scholars have empirically investigated cohabitation; however, little research explores what cohabitation means using a qualitative approach. Exploring the meaning of cohabitation can illuminate perceptions that might coincide with negative outcomes. Framed by Relational Dialectics Theory, a contrapuntal analysis of cohabiters' online stories (n=27) revealed three counter-discourses: Narratives of Cohabitation as a Normal Relationship, Cohabitation as an Easy Relationship, and Cohabitation as a Worthwhile Struggle. Each counter-discourse resisted …

Biodiversity And Ecosystem Function And The Design Of Tallgrass Restorations For Biomass Production, Dustin Robert Jon Graham

Dissertations and Theses @ UNI

Biodiversity and ecosystem function research (BEF) suggests species richness may provide high levels of ecosystem functions. However, few studies have applied a BEF perspective of restoration, which utilizes biodiversity to achieve increases in ecosystem functions. In this study, we test the application of the BEF perspective of restoration in the design of tallgrass prairie plantings as a biomass crops. Specifically, we examine the effects of planted species richness on biomass production, resistance to disturbance, and resistance to invasion by weeds.

Four seed mixes which range in species richness (1, 5, 16 and 32 species) were established in four, field-scale (0.33-0.55 …

Butterfly And Floral Community Dynamics At A Native Prairie Agrofuel Research Site, Benjamin J. Hoksch

Dissertations and Theses @ UNI

Agrofuel production in the Midwest has historically relied upon monoculture food crops (Zea mays and Glycine max) that do little to support biodiversity or maintain soil and water quality. The University of Northern Iowa’s Tallgrass Prairie Center is investigating the feasibility of establishing and harvesting diverse mixes of native prairie vegetation for use as a sustainable agrofuel. In 2009 48 research plots were established on three soil types, on land with a >30 year history of row crop production in Black Hawk County, IA. Each plot was seeded with one of four native prairie agrofuel crops: (1) Switchgrass1, (2) Grasses5 …

A Comparison Of The Effects Of Burning, Haying And Mowing On Plants And Small Mammals In A Tallgrass Prairie Reconstruction, Ryan Allan Neuhaus

Dissertations and Theses @ UNI

Fire is an effective management tool for reconstructed prairies. However, due to safety concerns, road departments and other prairie managers are sometimes reluctant to use fire. Therefore, alternative techniques to manage reconstructed prairie, such as mowing or haying, need to be considered. The goal of this study is to determine if mowing and/or haying can be used to manage vegetation in lieu of fire for prairie reconstructions. This study examines the effects of four management techniques on plant and small mammal species in a tallgrass prairie reconstruction. No management, mowing, haying, and burning were replicated six times using a split …

Ftc V. Actavis: The Patent-Antitrust Intersection Revisited, Glynn S. Lunney Jr

Faculty Scholarship

In FTC v. Actavis, the Supreme Court determined that courts should apply a rule of reason analysis to determine whether using a reverse payment settlement to resolve pharmaceutical patent litigation violates the antitrust laws. Essentially unique to pharmaceutical-patent litigation, a reverse payment settlement involves a payment from the patent-holder to generic challengers in return for the generics dropping their challenge to the patent(s) at issue and agreeing to remain out of the market. Such a settlement agreement enables the patent-holder to maintain exclusivity in the relevant market and to keep prices of the associated pharmaceutical higher than they would …

Cellulose Synthase (Cesa) Gene Expression Profiling Of Physcomitrella Patens, Mai L. Tran, Alison Roberts

Biological Sciences Faculty Publications

The Cellulose Synthase (CESA) gene family of seed plants comprises six clades that encode isoforms with conserved expression patterns and distinct functions in cellulose synthesis complex (CSC) formation and primary and secondary cell wall synthesis. In mosses, which have rosette CSCs like those of seed plants but lack lignified secondary cell walls, the CESA gene family diversified independently and includes no members of the six functionally distinct seed plant clades. There are seven CESA isoforms encoded in the genome of the moss Physcomitrella patens. However, only PpCESA5 has been characterized functionally and little information is available on the expression …

Three Essays On Shellfish Management In Rhode Island, Pratheesh Omana Sudhakaran

Open Access Dissertations

Shellfish resources are the main fishery resources commercially harvested and cultured in Rhode Island. Wild shellfish management in Rhode Island is undertaken by the RI Department of Environmental Management (DEM) aiming to achieve, among other objectives, conserving naturally occurring shellfish populations in RI waters and managing public health outcomes due to, water quality issues. However, for any management scheme or regulation to be effective, policy must recognize the economic forces at work when evaluating proposed intervention or regulation of shellfishing. Regulations would influence the harvesters’ behavior through the change in the harvested quantity or market price of the product and …

Three Essays On Co-Management In A Fishery, Mihoko Tegawa

Open Access Dissertations

Co-management has been recognized as an important scheme in successfully governing common-pool resources (Ostrom, 1990, 2002). Contrary to Hardin’s Tragedy of the Commons (1968) or Olson’s Logic of Collective Action (1965), empirical research has found many long-lasting self-governing communities through extensive case studies (Baland & Platteau, 1996; Ostrom, 1990; Wade, 1989). This is no exception in fishery (Pinkerton, 1994). Fishery cooperatives, where fishermen collectively manage the fishery, have been garnering much attention from both regulators and academics (Costello, 2012; Deacon, 2012; Townsend, Shotton, & Uchida, 2008). In fact, Northeast multispecies groundfish fishery in US has implemented a sector management system, …

Fair Fishing Human Rights And Sustainability In Bilateral Fishing Agreements Between The Eu And Developing Countries, Anna S. Antonova

Open Access Master's Theses

This project investigates bilateral fishing agreements between the European Union and developing states in order to assess the extent to which these agreements are as successful at implementing international law principles as European Union officials have claimed they are. Over the past two decades, European Union rhetoric has communicated an intent to take on a normative power role in advancing human rights and sustainable development approaches in the context of global fisheries policy. Officials have propagated an image of a “new Europe,” conscientious of its colonizing heritage, committed to promoting good maritime governance, and ensuring responsible fishing worldwide as part …

The Recreational Use Of Provincetown Harbor And Attitudes Towards Shellfish Aquaculture, Daniel Maggio

Open Access Master's Theses

Aquaculture refers to the breeding, rearing, and harvesting of plants and animals in all types of water environments including ponds, rivers, lakes, and the ocean (NOAA, 2014). In the United States shellfish aquaculture of mollusks experienced significant economic growth from 2005-2013. In 2005 the mollusk shellfish aquaculture industry was worth approximately $203,183,000, which grew to $328,567,000 in 2013 (USDA;NASS, 2013). In Provincetown, Massachusetts the interest of growth and development of shellfish aquaculture from local fishermen and town officials is increasing (Wisbauer, 2015).

Surveys were administered to four categories of users, as defined by the town's definitions: residents, non-residents, occupants, and …

The Supreme Court And The Transformation Of Juvenile Sentencing, Elizabeth S. Scott, Thomas Grisso, Marsha Levick, Laurence Steinberg

Faculty Scholarship

In the past decade, the Supreme Court has transformed the constitutional landscape of juvenile crime regulation. In three strongly worded opinions, the Court held that imposing harsh criminal sentences on juvenile offenders violates the Eighth Amendment prohibition against cruel and unusual punishment. In combination, these cases create a special status for juveniles under Eighth Amendment doctrine as a category of offenders whose culpability is mitigated by their youth and immaturity, even for the most serious offenses. The Court also emphasized that juveniles are more likely to reform than adult offenders, and that most should be given a meaningful opportunity to …

Commentary: Applying Positive Development Principles To Group Interventions For The Promotion Of Family Resilience In Pediatric Psychology, Jessica C. Kichler, Astrida S. Kaugars

Psychology Faculty Research and Publications

As described in the call for this special issue, resilience is often defined as “achieving one or more positive outcomes despite exposure to significant risk or adversity” (Hilliard, Harris, & Weissberg-Benchell, 2012, p. 739). Resilience is particularly relevant to pediatric psychology, as youth and their families are tasked with overcoming risk factors simply by the nature of a child’s diagnosis of a disease/chronic illness and subsequent medical management demands. In addition to identifying key resilience factors within this population, it is critical to develop empirically supported clinical interventions to promote healthy biological, psychological, and social development; reduce youth psychopathology; and …

Anti-Herding Regulation, Ian Ayres, Joshua Mitts

Faculty Scholarship

In some contexts, an individual’s choice to mimic the behavior of others, to join the herd, can increase systemic risk and retard the production of information. Herding can thus produce negative externalities. And in such situations, individuals by definition have insufficient incentives to separate from the herd. But the traditional regulatory response to externality problems is to impose across-the-board mandates. Command-and-control regulation tends to displace one pooling equilibrium by moving behavior to a new, mandated pool. Mortgage regulators, for example, might respond to an unregulated equilibrium where most homeowners start with 2% down by imposing a requirement that causes most …

Legal & Scientific Integrity In Advancing A "Land Degradation Neutral World", Shelley Welton, Michela Biasutti, Michael B. Gerrard

Faculty Scholarship

It is no secret that the fight against desertification isn't going well. In the two decades since the United Nations Convention to Combat Desertification ("UNCCD") came into force, desertification – defined as degradation in the quality of "arid, semi-arid, and dry subhumid" land areas – has worsened considerably. Recent United Nations estimates suggest that fifty-two percent of drylands currently under agricultural cultivation are moderately or severely degraded, and 12 million hectares of productive land become barren each year due to desertification and drought. And while drylands are the focus of the UNCCD, the challenge isn't limited to them: somewhere around …

Reconciling The Two Cultures : A Case Study Of The University Of Northern Iowa, Elizabeth Ann Collins

Dissertations and Theses @ UNI

In 1959, chemist and author Charles Percy Snow gave a Rede Lecture at the University of Cambridge in which he named “Two Cultures”—the sciences and the humanities—which, according to his experience as someone who worked in both, were at odds with one another. His words elicited impassioned responses from critics who either agreed with Snow, believing this to be a detriment to society, or vehemently disagreed, believing Snow’s statements to be unfounded, and even antagonistic. This conversation, which had also found relevance in the United States, continues to be important today, and has changed over the years as institutions of …

The New Permanency, Joshua Gupta-Kagan

Faculty Scholarship

Permanency is a pillar of child welfare law; children generally do better with legally permanent caretakers than in temporary foster care. Historically, when foster children cannot reunify with their parents, states have sought to terminate parental rights and find adoptive families. But recent legal reforms have created a continuum of permanency options, many of which permit ongoing legal relationships with biological parents and do not require termination of biological parents’ rights. Research has demonstrated that such options are as lasting as adoption, and can help more children leave foster care to legally permanent caretakers. This continuum promises to empower families …
