Predicting Removal Efficiency Of Reverse Osmosis Membranes With Respect To Emerging Substances Of Concern Using A Discriminant Function Analysis, Herrera Fernando J Pleitez

Electronic Theses and Dissertations 2010 - 2019

This paper presents the results of the spike tests performed in the alternative water supply pilot testing program for the City of Pembroke Pines. It establishes the effectiveness of a protocol that can be used to gain further insight on the rejection capacities of RO membranes. An in-depth study of the molecular descriptors affecting rejection by RO membranes is presented and used in the development of a discriminant function analysis. This analysis proved to be an effective way to predict the passage of Emerging Substances of Concern (ESOCs) through RO membrane. Further, a principal component (PC) analysis was performed to …

Population Distribution, Habitat Selection, And Life History Of The Slough Crayfish (Procambarus Fallax) In The Ridge-Slough Landscape Of The Central Everglades, Der Heiden Craig Van

Electronic Theses and Dissertations 2010 - 2019

Understanding where and why organisms are distributed in the environment are central themes in ecology. Animals live in environments in which they are subject to competing demands, such as the need to forage, to find mates, to reproduce, and to avoid predation. Optimal habitats for these various activities are usually distributed heterogeneously in the landscape and may vary both spatially and temporally, causing animals to adjust their locations in space and time to balance these conflicting demands. In this dissertation, I outline three studies of Procambarus fallax in the ridge-slough landscape of Water conservation Area 3A (WCS-3A). The first section …

Psychophysiological Measures Of Aggression And Victimization In Early Adolescence, Christopher D. Aults

Electronic Theses and Dissertations 2010 - 2019

Many cardiovascular psychophysiological studies have found evidence of lower arousal states in aggressive individuals and hyper-arousal states in individuals exposed to chronic stress. However, most of these studies have relied on clinical diagnoses or self-reports to identify aggressive and victimized individuals. The present study used peer nominations to identify aggressive, victimized, and non-aggressive or victimized adolescents (mean age = 12.09 yrs.) to examine if any psychophysiological differences exist during resting and startle conditions. ANOVAs revealed that high aggressive/low victimized adolescents had a lower resting heart period/rate compared to high victimized/low aggressive adolescents. Further analyses revealed a statistical trend of lower …

Principals' Knowledge Of Special Education Policies And Procedures, Lindsay. Jesteadt

Electronic Theses and Dissertations 2010 - 2019

Research has shown that most school leaders lack the knowledge necessary to deal with the many different aspects and issues that special education programs encompass. This lack of knowledge ultimately places special education teachers, programs, and students with disabilities at a clear disadvantage. With The No Child Left Behind Act (NCLB) of 2001 and the reauthorization of The Individuals with Disabilities Education Improvement Act (IDEA) in 2004, schools and school leaders are being held accountable for the learning gains of all students, including students with disabilities. This study sought to assess the knowledge of Florida school principals in the area …

Proposed Expanded Green Space Plan Using Gis For Natural Areas In Palm Beach County, Corrie. Rainyn

Electronic Theses and Dissertations 2010 - 2019

In the past 25 years, Palm Beach County has acquired more than 31 million acres of public preserves consisting of numerous native habitats that are home to threatened and endangered flora and fauna. Both endemic habitats and plant species benefit from expansion and connectivity through the adoption of native plants in surrounding areas. The next step in conserving these protected, larger areas is to identify ways to connect them in order to reduce their isolation and improve their likelihood of continued ecosystem health. This study aims to perform an analysis using a GIS database of Palm Beach County's Eastern urban …

Public Speaking As The Last Battlefield, Shaundi C. Newbolt

Electronic Theses and Dissertations 2010 - 2019

Communication scholars are in disagreement over the presence of online public speaking courses in higher education. Despite limited research on the Online Public Speaking model, it is quickly replacing the traditional public speaking model in American colleges and universities. This study used Burkean Cluster-Agon Analysis to uncover core concepts from four contemporary public speaking textbooks used in various classroom models (traditional, online and hybrid). Concepts were then compared with traditional core concepts of early speech communication to determine if technology has influenced contemporary core concepts. Results determined that contemporary core concepts from three of the four public speaking textbooks reflected …

Labor Law, New Governance, And The Ghent System, Matthew Dimick

Journal Articles

The Employee Free Choice Act (EFCA) was the most significant legislation proposed for reforming the National Labor Relations Act (NLRA) in over a generation and the centerpiece of the American labor movement’s revitalization strategy. Yet EFCA hews closely to the particular regulatory model established by the NLRA at the peak of the New Deal, now over seventy-five years ago. Further, recent scholarship suggests that traditional regulatory approaches are giving way to new kinds of governance methods for addressing social problems. Rather than reviving an old regulatory model, should “New Governance” approaches instead be sought for addressing problems in employment representation? …

Revisiting The Methodology And Application Of Value-At-Risk, Kyong. Chung

Electronic Theses and Dissertations 2010 - 2019

The main objective of this thesis is to simulate, evaluate and discuss three standard methodologies of calculating Value-at-Risk (VaR) : Historical simulation, the Variance-covariance method and Monte Carlo simulations. Historical simulation is the most common nonparametric method. The Variance-covariance and Monte Carlo simulations are widely used parametric methods. This thesis defines the three aforementioned VaR methodologies, and uses each to calculate 1-day VaR for a hypothetical portfolio through MATLAB simulations. The evaluation of the results shows that historical simulation yields the most reliable 1-day VaR for the hypothetical portfolio under extreme market conditions. Finally, this paper concludes with a suggestion …

Assessing Environmental Inequality In Portland, Oregon: An Exploration Of Local Environmental Justice Struggles, Jordan Douglas Folks

Dissertations and Theses

This thesis explores patterns of environmental inequality in Portland, Oregon; both the existence of spatial environmental inequalities and the structural and local forces which contribute to them. Research on environmental inequality, or inequitable exposure to toxins, has shown that minority and low-income populations experience the bulk of the exposure to environmental hazards. Although Portland is often cited as the archetype of a sustainable city, environmental inequality is a pervasive issue. This thesis examines the health inequalities that characterize underserved communities in Portland. Utilizing a mixed methods approach, the researcher uses 1) logistic regression to statistically assess the relationship between race, …

Supranationalism In The Fight Against Transnational Threats: A Comparative Study Of Asean And Eu Policy Responses To Human Trafficking, Nicholas M. Klynn

Dissertations and Theses

Transnational security threats are among the most pressing and complicated problems facing both governmental and non-governmental actors in today's world. Human trafficking is one example of contemporary transnational security threat that is relatively less studied compared to other transnational security threats. Because transnational security threats such as human trafficking exist above and outside the boundaries of state control, it may be supposed that a greater degree of supranationalism in the policy responses to them would yield better results in combatting these modern-day ills. Anti-trafficking efforts from the Association of Southeast Asian Nations and the European Union are examined to assess …

The Foreign Trade Antitrust Improvements Act: Do We Really Want To Return To American Banana?, Joseph P. Bauer

Journal Articles

The extra-territorial reach of the antitrust laws is subject to multiple constraints, including the Commerce Clause of the constitution, the text of the antitrust statutes, and a variety of policy considerations. At the beginning of the twentieth century, in the American Banana case, the Supreme Court severely limited the application of the antitrust laws to anti-competitive behavior beyond our shores. The next eighty years saw an expansion of their extra-territorial reach, by including within their coverage a range of foreign conduct which had domestic effects. However, confusion among the lower courts as to the extent of this coverage, as well …

Designing Wise Communities That Engage In Creative Problem Solving: An Analysis Of An Online Design Model, Charlotte Nirmalani Gunawardena, Ludmila Layne, Casey Frechette

University Libraries & Learning Sciences Faculty and Staff Publications

Addressing the conference theme of “design thinking,” this paper discusses an instructional design model, WisCom (Wisdom Communities) that we developed to build a wise learning community online, to solve open-ended, ill-structured problems such as solving a health crisis or an environmental disaster, which requires the exchange of multiple perspectives, inter-disciplinary thinking, creative problem solving, and social construction of knowledge. Based on socio-constructivist, sociocultural theories of learning and mediated cognition (Vygotsky, 1978), distributed cognition (Hutchins, 1995; Pea, 1993), group cognition (Stahl, 2006), research on how people learn (Bransford, Vye, Bateman, Brophy, & Roselli, 2004), and distance education design principles (Moore & …
