Federal V. State Effectiveness: An Analysis Of The Endangered Species Act And Current Potential Attempts At Reform, Nicholas Primo 2014 Pepperdine University

Federal V. State Effectiveness: An Analysis Of The Endangered Species Act And Current Potential Attempts At Reform, Nicholas Primo

Pepperdine Policy Review

In November 2013, several Congressional leaders drafted a new bill to reform the Endangered Species Act of 1973 (ESA). While the Endangered Species Management Self-Determination Act (ESMSDA) was the first major attempt at updating the crucial U.S. environmental policy in decades, it also inflamed environmentalist defenders of the original bill. More importantly, it raised several questions as to whether state or federal-oriented approaches to endangered species protection and environmental policy more broadly is ultimately more effective. This article analyzes the original 1973 ESA, followed by an analysis of the ESMSDA currently being considered. It will discuss the various strengths and …

Bringing together topic-related European Union-(EU)-funded projects, the so-called “NanoSafety Cluster” aims at identifying key areas for further research on risk assessment procedures for nanomaterials (NM). The outcome of NanoSafety Cluster Working Group 10, this commentary presents a vision for concern-driven integrated approaches for the (eco-)toxicological testing and assessment (IATA) of NM. Such approaches should start out by determining concerns, i.e. specific information needs for a given NM based on realistic exposure scenarios. Recognized concerns can be addressed in a set of tiers using standardized protocols for NM preparation and testing. Tier 1 includes determining physico-chemical properties, non-testing (e.g. structure …


Non-Additive Toxicity Of Bi-Metal Mixtures To Fathead Minnows, Natalie Rae Lynch 2014 Loyola University Chicago

Non-Additive Toxicity Of Bi-Metal Mixtures To Fathead Minnows, Natalie Rae Lynch

Master's Theses

Much research has been conducted to assess the toxicity of metals to aquatic organisms. Most of the research has focused on the toxicity of individual metals. Recently, attention has been paid to metal mixture toxicity because metals are usually present as mixtures in contaminated environments. The literature review indicates that metal mixtures may be additive, synergistic, or antagonistic to freshwater species. However, the data is not consistent and is dependent on the metal and organisms. The goal of this research is to use a systematic experimental design to characterize the toxicity of Cu, Zn, Cd and Ni mixtures to Pimephales …


The Performance Of Simple Artificial Floating Wetland Communities And Their Effects On Aquatic Nutrient Levels And Algal Abundance, Bradley L. Sleeth 2014 University of North Florida

The Performance Of Simple Artificial Floating Wetland Communities And Their Effects On Aquatic Nutrient Levels And Algal Abundance, Bradley L. Sleeth

UNF Graduate Theses and Dissertations

Harmful algal blooms are exponential increases in autotrophic microorganisms that proliferate in such a way that the surrounding environment, the local economy and the health of regional populations are negatively affected. Among the causes of these blooms are anthropogenic inputs of excess nitrogen and phosphorus into the environment through overfertilization. Floating treatment wetlands (FTW) have emerged as a novel method of reducing the negative impacts of these nutrient inputs by using artificial rafts to float normally emergent wetland plants on the surface of water bodies to assimilate excess nutrients. Because their use is so new, only limited research has been …


Message Matters: Application Of The Theory Of Planned Behavior To Increase Household Hazardous Waste Program Participation, Amy Dyer Cabaniss 2014 Antioch University of New England

Message Matters: Application Of The Theory Of Planned Behavior To Increase Household Hazardous Waste Program Participation, Amy Dyer Cabaniss

Antioch University Dissertations & Theses

Removing household hazardous waste (HHW) from the municipal solid waste stream is important to protect health, safety and the environment. Communities across the U.S. separate HHW from regular trash for disposal with hazardous waste, however nationally, participation rates are low with only five to ten percent of households estimated to participate in any given collection. This two-part study used the Theory of Planned Behavior (TPB) to understand individuals’ beliefs and attitudes toward HHW collections, and to develop a print message intervention to increase participation. In Study 1, respondents (N = 983) completed a survey administered to homeowners in the Connecticut …

Repeated Asenapine Treatment Produces A Sensitization Effect In Two Preclinical Tests Of Antipsychotic Activity, Rongyin Qin, Yingzhu Chen, Ming Li

Department of Psychology: Faculty Publications

Among several commonly used atypical antipsychotic drugs, olanzapine and risperidone cause a sensitization effect in the conditioned avoidance response (CAR) and phencyclidine (PCP)- induced hyperlocomotion paradigms – two well established animal tests of antipsychotic drugs, whereas clozapine causes a tolerance effect. Asenapine is a novel antipsychotic drug recently approved for the treatment of schizophrenia and manic disorders. It shares several receptor binding sites and behavioral features with other atypical antipsychotic drugs. However, it is not clear what type of repeated effect (sensitization or tolerance) asenapine would induce, and whether such an effect is transferrable to other atypicals. In this study, …


Comparison Of Theophylline And 8-Cyclopentyltheophylline On The Heart Rates Of Neonatal Rats, Stephanie Arnold 2013 Eastern Illinois University

Comparison Of Theophylline And 8-Cyclopentyltheophylline On The Heart Rates Of Neonatal Rats, Stephanie Arnold

Undergraduate Honors Theses

Neonatal apnea is a serious condition that affects the health of infants, especially those born prematurely. To stimulate breathing, methylxanthine drugs, such as theophylline and caffeine, are administered to reverse this condition in humans and avoid the use of breathing-assistance equipment. These drugs cause stimulation of the central nervous system and the heart, however, both detrimental side effects in preterm infants. Antagonism of adenosine receptors is the proposed mechanism of methylxanthine action. Synthetic chemists have produced xanthine analogs with increased affinity for adenosine receptors that could lead to respiratory stimulation while reducing cardiostimulant effects. For this study, theophylline and 8-cyclopentyltheophylline …
