Hollis, Regina G. Ziegler, Mark P. Purdue, Barry I. Graubard

Kinesiology and Public Health

Hypovitaminosis D may be associated with diabetes, hypertension and CHD. However, because studies examining the associations of all three chronic conditions with circulating 25-hydroxyvitamin D (25(0H)D) and 1,25-dihydroxyvitamin D (1,25(0H)₂D) are limited, we examined these associations in the US Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial (n 2465). Caucasian PLCO participants selected as controls in previous nested case-control studies of 25(0H)D and 1,25(0H)₂D were included in this analysis. Diabetes, CHD and hypertension prevalence, risk factors for these conditions and intake of vitamin D and Ca were collected from a baseline questionnaire. Results indicated …

Influence Of Vineyard Floor Management Practices On Soil Aggregate Stability, Total Soil Carbon And Grapevine Yield, Kimberly Ellen Adams

Master's Theses

Soil aggregates provide pore spaces of various sizes supplying water, gases and nutrients to plant roots and microorganisms, and facilitate moisture retention and availability. Soil aggregate stability is indicative of soil biological and structural health, and is increased by soil carbon derived from plant roots and the soil microbial biomass. Aggregate stability and soil carbon can be enhanced by increasing organic matter through compost additions or by planting cover crops. Additionally, aggregate stability is enhanced by arbuscular mycorrhizal fungi (AMF) that form a symbiotic association with plant roots, and consolidate soil particles into aggregates through hyphal networks and through the …

Bridging The Marine-Terrestrial Disconnect To Improve Marine Coastal Zone Science And Management, Benjamin I. Ruttenberg, Elise F. Granek

Biological Sciences

Coastal zone ecosystems sit between larger terrestrial and marine environments and, therefore, are strongly affected by processes occurring in both systems. Marine coastal zone systems provide a range of benefits to humans, and yet many have been significantly degraded as a result of direct and indirect human impacts. Management efforts have been hampered by disconnects both between management and scientific research and across linked marine–terrestrial systems. Management jurisdictions often start or end at the shoreline, and multiple agencies at different levels of government often have overlapping or conflicting management goals or priorities, or suffer from a lack of knowledge or …

Innate And Learned Preferences For Sweet Taste During Childhood, Alison K. Ventura, Julie A. Mennella

Kinesiology and Public Health

Purpose of review: In nature, carbohydrates are a source of energy often equated with sweetness, the detection of which is associated with powerful hedonic appeal. Intakes of processed carbohydrates in the form of added sugars and sugar-sweetened beverages have risen consistently among all age groups over the last two decades. In this review, we describe the biological underpinnings that drive the consumption of sweet-tasting foods among pediatric populations.

Recent findings: Scientific literature suggests that children's liking for all that is sweet is not solely a product of modern-day technology and advertising but reflects their basic biology. In fact, heightened preference …

The Education Reform Of Tap And Value-Added Assessment: Teacher Merit Pay That Reinvigorates Standardized Testing And Detracts From 21st Century Learning Skills, Shawn Scharer Greenelsh

Master's Theses

In the last two decades, ignoring the bulk of educational research findings, policymakers shaped educational policy into a standardized testing movement that now dominates education. Now, to comply with No Child Left Behind, teachers and administrators shape curriculum in a way that maximizes student achievement measured by these tests. Recently, business and educational leaders initiated a reform movement to broaden curriculum, narrowed by this inadequate standardized testing movement, so that necessary 21st century learning skills can be practiced through project-based learning. The Federal Government’s enforcement of power over education created the climate that defined the current educational policy that gave …

Teaching Sustainability Analysis In Electronics Lecture Courses, David Braun

Electrical Engineering

Based on positive prior experiences teaching sustainability analysis in electronics laboratory courses, this work explores techniques for teaching sustainability analysis in lecture courses. As difficult as it may seem to incorporate sustainability into integrated circuit courses or other engineering courses, it may prove as easy as asking students to consider how the coursework relates to sustainability issues.

The need to educate students “to design a system, component, or process to meet desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability” has gained sufficient value to deserve its own ABET Program Outcome, …

Predator-Induced Demographic Shifts In Coral Reef Fish Assemblages, Benjamin I. Ruttenberg, Scott L. Hamilton, Sheila M. Walsh, Mary K. Donovan, Alan Friedlander, Edward Demartini, Enric Sala, Stuart A. Sandin

Biological Sciences

In recent years, it has become apparent that human impacts have altered community structure in coastal and marine ecosystems worldwide. Of these, fishing is one of the most pervasive, and a growing body of work suggests that fishing can have strong effects on the ecology of target species, especially top predators. However, the effects of removing top predators on lower trophic groups of prey fishes are less clear, particularly in highly diverse and trophically complex coral reef ecosystems. We examined patterns of abundance, size structure, and age-based demography through surveys and collection-based studies of five fish species from a variety …

Thermal Analysis Of The Cubesat Cp3 Satellite, Jonas Friedel, Sean Mckibbon

Aerospace Engineering

Due to inconsistencies found in the on-orbit thermal data from the CubeSat CP3 satellite between 2007 and 2011, further analysis is performed on a larger number of data from August 2010 through April 2011, aiming to find an explanation for the overall increasing measured temperatures and shortening peak periods. Therefore, the satellite power data as well as orbital anomalies are analyzed leading to the conclusion that the satellite was temporarily (January – March 2011) orbiting with significantly increased sun exposure causing the higher temperatures. The shortened temperature peak periods are explained by alternating albedo values as the main influence in …
