A Model Of How Different Biology Experts Explain Molecular And Cellular Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez 2015 Purdue University

A Model Of How Different Biology Experts Explain Molecular And Cellular Mechanisms, Caleb M. Trujillo, Trevor R. Anderson, Nancy J. Pelaez

PIBERG Publications

Constructing explanations is an essential skill for all science learners. The goal of this project was to model the key components of expert explanation of molecular and cellular mechanisms. As such, we asked: What is an appropriate model of the components of explanation used by biology experts to explain molecular and cellular mechanisms? Do explanations made by experts from different biology subdisciplines at a university support the validity of this model? Guided by the modeling framework of R. S. Justi and J. K. Gilbert, the validity of an initial model was tested by asking seven biologists to explain a molecular ...


Illness And God's Will, John Sherret 2015 Liberty University

Illness And God's Will, John Sherret

Senior Honors Theses

Originally, God never put sickness on people. After the fall, the early history of man as recorded in the Bible further demonstrates Him refraining to use sickness. However, once the law was instituted God began to use sickness as a punishment. In the Old Testament, sickness was always defined as a curse and never a blessing. It was used by God to curse people for disobeying the law. In the New Testament, God was seen healing the multitudes instead of cursing them. Through the atonement of Jesus, believers have been redeemed from the curse of the law (Galatians 3:13 ...


Habitat Features Predict The Distribution Of Recreational Shooters In The Morley Nelson Snake River Birds Of Prey National Conservation Area, Emily R. Sun, Benjamin P. Pauli, Zoe Tinkle, Romaric Mukuna, Daniel Wolfe, Jennifer S. Forbey, Julie Heath 2015 Boise State University

Habitat Features Predict The Distribution Of Recreational Shooters In The Morley Nelson Snake River Birds Of Prey National Conservation Area, Emily R. Sun, Benjamin P. Pauli, Zoe Tinkle, Romaric Mukuna, Daniel Wolfe, Jennifer S. Forbey, Julie Heath

College of Arts and Sciences Presentations

The Morley Nelson Snake River Birds of Prey National Conservation Area (NCA) is a popular destination of many Treasure Valley residents. There, recreationists participate in various pastimes such as target shooting, recreational shooting/hunting, and wildlife viewing. However, these activities have the potential to interfere with one another. Recreational shooting of Piute ground squirrels (Urocitellus mollis) could affect prey availability and scavenging opportunities for associated raptor species, most notably local golden eagle (Aquila chrysaetos) populations. To assess possible interactions among shooters, prey and raptors, the spatial density and habitat preference of human shooters must be determined. We hypothesized that higher ...


Concomitant Uptake Of Antimicrobials And Salmonella In Soil And Into Lettuce Following Wastewater Irrigation, J. Brett Sallach, Yuping Zhang, Laurie Hodges, Daniel D. Snow, Xu Li, Shannon L. Bartelt-Hunt 2015 University of Nebraska--Lincoln

Concomitant Uptake Of Antimicrobials And Salmonella In Soil And Into Lettuce Following Wastewater Irrigation, J. Brett Sallach, Yuping Zhang, Laurie Hodges, Daniel D. Snow, Xu Li, Shannon L. Bartelt-Hunt

Civil Engineering Faculty Publications

The use of wastewater for irrigation may introduce antimicrobials and human pathogens into the food supply through vegetative uptake. The objective of this study was to investigate the uptake of three antimicrobials and Salmonella in two lettuce cultivars. After repeated subirrigation with synthetic wastewater, lettuce leaves and soil were collected at three sequential harvests. The internalization frequency of Salmonella in lettuce was low. A soil horizon-influenced Salmonella concentration gradient was determined with concentrations in bottom soil 2 log CFU/g higher than in top soil. Lincomycin and sulfamethoxazole were recovered from lettuce leaves at concentrations as high as 822 ng ...


Does Personality Affect The Probability That Piute Ground Squrriels (Urocitellus Mollis) Will Be Shot By Recreational Hunters?, Daniel Wolfe, Zoe Tinkle, Benjamin P. Pauli, Emily Sun, Romaric Mukuna, Jennifer S. Forbey, Julie Heath 2015 Boise State University

Does Personality Affect The Probability That Piute Ground Squrriels (Urocitellus Mollis) Will Be Shot By Recreational Hunters?, Daniel Wolfe, Zoe Tinkle, Benjamin P. Pauli, Emily Sun, Romaric Mukuna, Jennifer S. Forbey, Julie Heath

College of Arts and Sciences Presentations

Recreational shooting of Piute ground squirrels (Urocitellus mollis) in southern Idaho is an activity growing in popularity. One factor that may influence shooting success is the personality of individuals within a population. We hypothesized that bold individual ground squirrels would be more/less likely to be targeted by a hunter and would be more/less disturbed by gun fire. To test these hypotheses, we simulated recreational shooting to identify which personalities are more susceptible hunters and more responsive to gun fire. We preformed simulations in March of 2015 on a population of Piute ground squirrels with known personalities. Bold and ...


Songbirds And Their Sunglasses: A Study Demonstrating Avian Attraction To Highly Polarizing Horizontal Surfaces, Imaani J. Easthausen 2015 Bard College

Songbirds And Their Sunglasses: A Study Demonstrating Avian Attraction To Highly Polarizing Horizontal Surfaces, Imaani J. Easthausen

Senior Projects Spring 2015

Research done in migratory birds over the last few decades has provided strong evidence suggesting that birds use cues from polarized light in the sky to guide orientation and navigation. If birds are able to detect skylight polarization patterns, then they could also be sensitive to polarized light in other non-migratory contexts – a possibility that has received minimal attention in the literature. Aquatic insects are known to depend on polarized light to identify water. While, historically, this has been a reliable cue, the rise and spread of urbanization has resulted in an increase in anthropogenic sources of polarized light – such ...


Tillage, Cover Crop And Nitrogen Fertilization Effects On Soil Microbial Carbon Dynamics Under Long-Term Cotton Production, Molefi Jacob Mpheshea 2014 University of Tennessee - Knoxville

Tillage, Cover Crop And Nitrogen Fertilization Effects On Soil Microbial Carbon Dynamics Under Long-Term Cotton Production, Molefi Jacob Mpheshea

Masters Theses

Effective soil management requires a deeper understanding of how internal soil carbon (C) works. This is vital as cycling is tightly linked with nutrient cycling processes. This study evaluated the effect of agronomic practices including tillage (no-till and tilled), cover crops (no cover, hairy vetch - Vicia villosa L, and winter wheat - Triticum aestivum. L ) and different N fertilizer rates ( 0, 34 and 101 kg N per hectare ) on soil microbial C dynamics as measured by soil microbial biomass C (SMBC) along with soil microbial respiration over the 2013 cotton growing season at Jackson, West Tennessee. The study was set as ...


Northern Bobwhite (Colinus Virginianus) Habitat Selection On A Reclaimed Surface Mine In Western Kentucky, Ashley Marie Unger 2014 University of Tennessee - Knoxville

Northern Bobwhite (Colinus Virginianus) Habitat Selection On A Reclaimed Surface Mine In Western Kentucky, Ashley Marie Unger

Masters Theses

Reclaimed mines present an opportunity to provide large tracts of habitat for northern bobwhite (Colinus virginianus). Reclaimed mine sites are commonly planted to non–native species, including sericea lespedeza (Lespedeza cuneata) and tall fescue (Schedonorus phoenix), which can inhibit growth of more desirable plant species and limit favorable structure for bobwhite. Although bobwhite are found on reclaimed mine sites, there have been no studies documenting how bobwhites use various vegetation types common to reclaimed mine land. Habitat use studies can provide information on how bobwhite select vegetation types on these landscapes and help direct future management decisions. We trapped and ...

Un Cuento Satírico En Medio Del Debate Sobre El Darwinismo En México, Miguel A. Fernández Delgado MAFD 2014 University of South Florida

Un Cuento Satírico En Medio Del Debate Sobre El Darwinismo En México, Miguel A. Fernández Delgado Mafd

Alambique: Revista académica de ciencia ficción y fantasia / Jornal acadêmico de ficção científica e fantasía

Charles Darwin's theory of biological evolution of species was accepted or rejected by Mexican scientists, including Gabino Barreda, representative of Comte's philosophy. It was also included by Justo Sierra in a history book for the Escuela Nacional Preparatoria, a decision which raised a lot of criticism from conservative groups. It is also discussed the implications of social Darwinism in the early Twentieth Century Mexico. The document we offer is a satire published in those years, which resembles the tone of Swift's Gulliver Travels.


Aquaponics And Basil Plant Density, Danika L. MacMaster, Brook Murphy, Dudley Burton 2014 CSU-Sacramento

Aquaponics And Basil Plant Density, Danika L. Macmaster, Brook Murphy, Dudley Burton

STAR (STEM Teacher and Researcher) Program Posters

Aquaponics is the use of water from a fish tank to provide nutrients to plants in a soil-less environment. The rocks cultivate the bacteria that turns the ammonia into nitrates that the plants need, and the plant bed functions as a filter for the fish tank. In this study, with the guidance of Doctor Dudley Burton, Doctor Brook Murphy, we researched the optimal plant density for basil in an Aquaponics system. We attempted to control or measure all the other variables to consider, as to isolate the variable of distance between plants. The water flow was spread through the plant ...

The question of whether there is or was life on Mars has been one of the most pivotal since Schiaparellis’ telescopic observations of the red planet. With the advent of the space age, this question can be addressed directly by exploring the surface of Mars and by bringing samples to Earth for analysis. The latter, however, is not free of problems. Life can be found virtually everywhere on Earth. Hence the potential for contaminating the Mars samples and compromising their scientific integrity is not negligible. Conversely, if life is present in samples from Mars, this may represent a potential source ...

Soil Moisture And Temperature Conditions Related To Cheatgrass Establishment Failure, Lauren Ducas 2014 Utah State University

Soil Moisture And Temperature Conditions Related To Cheatgrass Establishment Failure, Lauren Ducas

All Graduate Plan B and other Reports

Cheatgrass, a widespread invasive plant, has taken over many rangelands in the Intermountain West. Restoration efforts have not met with much success. Early in cheatgrass’ growth period, if air temperatures fall too low and soils too dry, growth may be disrupted to the point of death of the cheatgrass plants. In this case, cheatgrass stands may revert to bare ground, providing opportunities for other invasive plants to establish, or possible restoration of native perennials. We conducted a computer modeling and observational field study to determine if air temperature and soil moisture conditions below its tolerance are associated with failure of ...


Death Acceptance In Widowhood, Staci Ernsberger 2014 University of Kentucky

Death Acceptance In Widowhood, Staci Ernsberger

Theses and Dissertations--Family Sciences

Death is a universal event that all living things experience. Older adults, in particular, are more mindful of death than younger generations because of their proximity and increased exposure to it. In addition, thoughts of one’s own death often increase with the death of a spouse. Previous research has explored the role of social support in death acceptance and the effect of previous marital satisfaction on a widow’s well-being. However, there is a lack of research regarding the experience of a widow’s personal death acceptance relative to spousal death acceptance and marital satisfaction. This phenomenological study aims ...

Great Salt Lake's Two Deep Brine Layers, Wayne A. Wurtsbaugh

Wayne A. Wurtsbaugh

Two major causeways that divide the Great Salt Lake have radically changed salt balances in different sections of the lake, and have caused deep brine layers to form. For you scrabble buffs, limnologists call these layers “monimolimnions”. In 1959 the Southern Pacific Railway built a 13- mile rock-fill causeway across the main lake, dividing it in half. T

U.S. Environmental Protection Agency Papers

Nonpoint source pollution from agriculture and urbanization is increasing globally at the same time climate extremes have increased in frequency and intensity. We review >200 studies of hydrologic and gaseous fluxes and show how the interaction between land use and climate variability alters magnitude and frequency of carbon, nutrient, and greenhouse gas pulses in watersheds. Agricultural and urban watersheds respond similarly to climate variability due to headwater alteration and loss of ecosystem services to buffer runoff and temperature changes. Organic carbon concentrations/exports increase and organic carbon quality changes with runoff. Nitrogen and phosphorus exports increase during floods (sometimes by ...


Modern Cavemen? Stereotypes And Reality Of The Ancestral Health Movement, David B. Schwartz, Hamilton M. Stapell 2013 Princeton University

Modern Cavemen? Stereotypes And Reality Of The Ancestral Health Movement, David B. Schwartz, Hamilton M. Stapell

Journal of Evolution and Health

Both academic and popular interest in the ancestral health movement, or “paleo” lifestyle, has grown rapidly in recent years. More people than ever are joining the movement, and more books and articles are being published on the topic. Media coverage and certain societal preconceptions of the movement have also increased. More often than not, followers of a paleo lifestyle are thought to be “modern cavemen”: athletic, single, meat-eating, young, white, and male. To test whether or not these stereotypes are true, the authors of the present study created the first large, academic survey (N = 3,967) of the ancestral health ...
