Is Federal Preemption Efficient In Cellular Phone Regulation, Thomas W. Hazlett

Federal Communications Law Journal

While many recent state-level efforts to regulate various aspects of the cellular phone industry have been abandoned in favor of federal regulations, other attempts by state regulators still exist. For this reason, Thomas Hazlett proposes that federal regulation is generally more appropriate than state-level action, due to the nature of the cellular industry. After a brief history of the industry, the author analyzes the pros and cons associated with state and federal regulation. The Article then proceeds to address the efficiencies created by national networks and proposes that the fragmentation of controlling regulatory power would reduce these efficiencies. Following a …

Ambulatory Blood Pressure Monitoring. A Pediatric Review, Aftab S. Chishti

Saudi Medical Journal

Hypertension is one of the major contributors to cardiovascular, renal and central nervous system morbidity and mortality. Although it is more prevalent in the adult population, hypertension and its sequelae are being seen in the pediatric population with increasing frequency. Blood pressure (BP) is not a static phenomenon. It is highly variable, changing constantly in response to various activities, stimuli, and stresses. Consideration of all of these factors make intermittent clinic BP measurements less effective in accounting for BP rhythmicity so ambulatory BP monitoring has emerged as a useful tool to give a detailed analysis of BP patterns during the …

Development Of A Method For Determining Antioxidant Efficacy Against Hydroxyl Radicals, Cherie Hacker

Masters Theses

Hydroxyl free radicals are biologically important molecules in that they attack proteins, lipids and DNA to obtain an electron to fill their outer valence shell. The consequences of such attacks include protein degradation, lipid peroxidation and DNA damage, which leads to many diseases and cancer. While there are many antioxidant assays available to predict anti-radical properties of compounds against different free radicals, the assessment of hydroxyl radical damage has been challenging. This is due to the extremely high reaction rate of hydroxyl radicals. The present study defines an in vitro assay that quantitatively detects antioxidant efficacy against hydroxyl free radicals, …

Fungi Associated With Northern Red Oak (Quercus Rubra ) Acorns, Dawn M. Washington

Graduate Theses, Dissertations, and Problem Reports (ETD)

Poor regeneration of northern red oak is widespread in the central hardwood region. A two-part study was conducted to determine what fungi are associated with and cause cotyledon discoloration of northern red oak acorns. The field study determined that simulated small mammal notching, surface sowing, time, and site all play a significant role in the amount of cotyledon discoloration in acorns as well as the number of acorns with discoloration. However, germination rate was only affected by site and surface sowing, while seedling vigor ratings were actually higher when acorns had discolored cotyledons. The five species of fungi isolated most …

Effect Of Heavy Metals On Bacteria, Elena Vratonjic

Theses and Dissertations

Heavy metals have become devastating environmental contaminants due to their widespread use in the manufacture of electronics, plastics, batteries and dyes. The discharge of heavy metals into the environment has caused concern about their effects on the ecosystem. Many metals are essential for growth in small amounts. However, at higher concentrations heavy metals are toxic because they bind to organic compounds. This accounts for their effects on some important parts of the cell structure, like their ability to denature protein molecules. The initial objective of this study was to find out the growth rate of E.coli and M.roseus in the …

Antipredator Behavior And Physiology Determine Lestes Species Turnover Along The Pond-Permanence Gradient, Robby Stoks, Mark A. Mcpeek

Dartmouth Scholarship

Identifying key traits that shape trade-offs that restrict species to only a subset of environmental gradients is crucial to understanding and predicting species turnover. Previous field experiments have shown that larvae of Lestes damselfly species segregate along the entire gradient of pond permanence and predator presence and that differential predation risk and life history constraints together shape their distribution. Here, we report laboratory experiments that identify key differences in behavior and physiology among species that structure their distributions along this gradient. The absence of adaptive antipredator behavioral responses against large dragonfly larvae and fish of Lestes dryas, the only species …

Response Cost In The Treatment Of Lunging In Dogs, Jennifer L. Sobie

Masters Theses

Contemporary professional applied animal behavior management employs a diagnostic and treatment approach for unwanted pet behavior that incorporates ethology-based causal factors. As in behavior therapy for humans, behavioral assessment includes descriptive functional analysis when possible to determine relevant contingency variables. But this information is then considered in the context of an appropriate motivational classification, such as social or prey-directed motivation or fear-motivated, and treatments are designed accordingly. A different view is that behavior can be treated effectively without a presumption of the motivation through analysis of the manifestation of the behavior itself. This study sought to evaluate the efficacy of …

Using Social Marketing To Plan A Nutrition Education Program Targeting Teens, Gwenn Snow, Jamie Benedict

Journal of Extension

Using focus group interviews, information was gathered from teens describing their perceptions about the benefits and barriers of consuming select nutrient-dense foods, such as dark-green leafy and deep-yellow vegetables, fruits, low-fat dairy foods, and whole grains, and their preferences for learning about foods and nutrition. The article demonstrates how social marketing was used to gather, assess, and use descriptive information to plan a nutrition education program targeting teens. While the content was specific to nutrition education and teens, the concepts presented are appropriate for Extension Educators, and applicable to a broad range of health behaviors.

County Agent Views About Facilitating Public Education And Discussion Of Genetic Engineering Use In Agriculture, J Lynne Brown, Nancy Ellen Kiernan, Elaine S. Smith, Luanne Hughes

Journal of Extension

We conducted seven focus groups with Extension agents from three northeast states in Spring 2000 to learn what agents knew about genetic engineering (GE) applications in agriculture, their view of Extension's role in public discussion and education, and the training needed to assume such a role. While participating agents together knew a fair amount about their target audiences' perceptions of GE, they felt unprepared to deal with the challenges of public issues education in light of the current public debate, the publics' low science literacy, and their own science background. Their expressed training needs reflected these challenges.

Studies Of The Effects Of Pancreatic Beta Cell Antioxidant Transgenes On Experimental Models Of Diabetes., Hainan Chen

Electronic Theses and Dissertations

Pancreatic beta cells are extremely vulnerable to the destruction of Reactive Oxygen Species (ROS). In both type 1 and type 2 diabetes ROS are involved in the loss of U+000DF-cells. We hypothesized that the deficiency in ROS detoxifying system of U+000DF-cells resulted in U+000DF-cell vulnerability and enhanced ROS protection would protect from diabetes. To test this hypothesis, transgenic mice with overexpression of U+000DF-cell antioxidant protein metallothionein (MT), manganese superoxide dismutase (MnSOD) and catalase were produced on an FVB background. Initial studies demonstrated that these transgenes did not affect U+000DF-cell normal function and morphology. But those transgenes significantly protected pancreatic islets …

Which Is The Fairest One Of All? A Positive Analysis Of Justice Theories, James Konow

Economics Faculty Works

This paper evaluates numerous positive and normative theories of justice in positive terms, i.e., in terms of how accurately they describe the impartial fairness preferences of real people. In addition, the paper proposes and defends an integrated justice theory based on preferences over four distinct and sometimes conflicting forces. These forces frame the analysis of the individual theories and inspire four corresponding theoretical classes: equality and need, utilitarianism and welfare economics, equity and desert, and context. This synthesis enables one to treat justice rigorously and to reconcile results that often appear contradictory or at odds with alternative theories.
