A Healthy Brain: Use It Or Lose It!, Elizabeth B. Fauth, Maria C. Norton 2017 Utah State University

A Healthy Brain: Use It Or Lose It!, Elizabeth B. Fauth, Maria C. Norton

All Current Publications

Challenging your muscles makes for strong healthy muscles, and challenging your brain cells makes for a strong healthy brain. Build up your brain’s cognitive reserve – create a well-connected, high-capacity brain – through overall healthy behaviors (diet and exercise) and making mentally challenging activities part of your daily life. The more options your brain has to get its signals sent, the better able it is to handle areas of damage. A well-connected brain may be better able to delay or prevent diseases like Alzheimer’s.


Dating The Terrestrial Invasion Of The Cyclophoroidea (Mollusca:Gastropoda) Using The Fossilized Birth-Death Model, Timothy Gervascio 2017 SUNY College of Environmental Science and Forestry

Dating The Terrestrial Invasion Of The Cyclophoroidea (Mollusca:Gastropoda) Using The Fossilized Birth-Death Model, Timothy Gervascio

Honors Theses

Despite their vast diversity, few metazoan lineages have made the transition from marine to terrestrial habitats. These transitions must have been accompanied by dramatic shifts in the physiology and ecology of the lineages, marking major evolutionary events that have shaped the diversity we see today. Among the Metazoa, gastropod molluscs have been among the most successful at making the transition, comprising at least 12 separate transitions. This unusual history makes them particularly suitable for studying the evolutionary context of these major events. The development of new relaxed molecular clock methods for seamlessly integrating molecular and fossil data provides new possibilities ...

Gosnell Studies And Communicates Ecological Concerns, Aldemaro Romero Jr. 2017 CUNY Bernard M Baruch College

Gosnell Studies And Communicates Ecological Concerns, Aldemaro Romero Jr.

Publications and Research

Scientists who study environmental problems know that the more you work in the field, the more insight you gain into how to solve problems. In other words, the more field experience you have, the deeper your understanding of nature.

One scientist who has had a lot of field experience is Dr. Stephen Gosnell, and his interest in the environment began when he was still a child. “I had interest really early. I grew up in rural South Carolina in a very small town called Landrum. I was outside on a regular basis, playing in the streams and creeks around me ...


Beyond The Obvious: Emerging Contaminants And Biogeochemistry As A Cause And Solution For Nitrogen Pollution, Stephanie L. DeVries 2017 The Graduate Center, City University of New York

Beyond The Obvious: Emerging Contaminants And Biogeochemistry As A Cause And Solution For Nitrogen Pollution, Stephanie L. Devries

All Dissertations, Theses, and Capstone Projects

Following a comprehensive review of the occurrence and impacts of antibiotics and related pharmaceutical compounds on the terrestrial N-cycle, three experiments were performed to explore the topic of biogeochemistry as a source or a sink for N-pollution. The first of these experiments addresses the question of whether environmentally relevant concentrations of antibiotics (µg·kg-1) have a significant effect on denitrification or N2O production, a question that has not been well addressed in previous studies. Having determined that there is a significant shift, the second study aims to comprehensively follow changes to soil N pools and N2 ...


Bioethics In The Work Of Ernest Everett Just: + Missing - Some 400 Pages, Theodore Walker 2017 Southern Methodist University

Bioethics In The Work Of Ernest Everett Just: + Missing - Some 400 Pages, Theodore Walker

Perkins Faculty Research and Special Events

Biology + ethics = bioethics. Here we see that Howard University biologist Ernest Everett Just (born 1883, died 1941) connected biology to ethics.

According to Just, various forms of specific biology (including especially cell biology) plus “general biology” are necessary for explaining adequately the origin of ethical behaviors. Social ethical behaviors, especially mutual aid and cooperative interactions with others and the environment, are essential to evolutionary advances among living creatures, ranging from humans to cells. Accordingly, theory of ethics (moral theory) should have roots in biology.

Also, Just wrote an unpublished book-length manuscript—“some 400 typed pages” (Just 1940)—on seeking the ...


Human-Nonhuman Chimeras, Ontology, And Dignity: A Constructivist Approach To The Ethics Of Conducting Research On Cross-Species Hybrids, Jonathan M. Vajda 2017 Western Michigan University

Human-Nonhuman Chimeras, Ontology, And Dignity: A Constructivist Approach To The Ethics Of Conducting Research On Cross-Species Hybrids, Jonathan M. Vajda

The Hilltop Review

Developments in biological technology in the last few decades highlight the surprising and ever-expanding practical benefits of stem cells. With this progress, the possibility of combining human and nonhuman organisms is a reality, with ethical boundaries that are not readily obvious. These inter-species hybrids are of a larger class of biological entities called “chimeras.” As the concept of a human-nonhuman creature is conjured in our minds, either incredulous wonder or grotesque horror is likely to follow. This paper seeks to mitigate those worries and demotivate reasonable concerns raised against chimera research, all the while pressing current ethical positions toward their ...


The Finney County, Kansas Community Assessment Process: Fact Book, Debra J. Bolton PhD, Shannon L. Dick M.S. 2017 Kansas State University

The Finney County, Kansas Community Assessment Process: Fact Book, Debra J. Bolton Phd, Shannon L. Dick M.S.

Dr. Debra Bolton

This multi-lingual/multi-cultural study was called, Community Assets Processt, by the groups that “commissioned” it: Finnup Foundation, Finney County K-State Research & Extension, Western Kansas Community Foundation, Finney County United Way, Finney County Health Department, United Methodist Community Health Center (UMMAM), Center for Children and Families, Garden City Recreation Commission, and the Garden City Cultural Relations Board, because we intend for this to be an ongoing discussion. An objective, for those promoting the study, was to connect foundation, state, and federal funding with activities or services that addressed the true needs of people living in Finney County. The group was looking for data that would offer insights on ways to address the needs of diverse audiences through human services agencies, County Extension, the schools, churches, and other entities working with community members of Finney County. Initially, an online survey was sent to directors of Finney County’s human service organization/agencies and schools. Directors were asked what sorts of data were required to help them quantify the needs of their client/customer bases. It was from those responses that the committee designed the survey instrument. The objective of the resulting survey instrument was to gather data that would: Identify resources available in Finney County (a Minority-majority county) Identify services needed in the community Capture information regarding well-being of people in Finney County Feature General Demographic (gender, age, race/ethnicity, education, household income) Length of years lived in Finney County Primary and secondary languages spoken at home (the survey was conducted in four (4) languages) Educational needs Health questions (insurance, health conditions, mental health, medical care, etc.) Social and health needs; and Questions to measure community engagement and social involvement Target individuals and groups of varying ages, socio-economic backgrounds, ethnic backgrounds, and religious affiliations. Target survey respondents 18 years or older Keep survey respondents’ identities confidential since the study was approved by Kansas State University’s Institutional Review Board for compliance in Research with Human Subjects. Data were gathered from about 1% of Finney County’s population through surveys and focus groups conducted in four languages better to understand the ...

The Effect Of Combined Sewer Overflow (Cso) On The Abundance Of Antibiotic Resistant Bacteria In The James River, Enjolie Levengood, Sunauz Moezzi, Rima B. Franklin

Rice Rivers Center Research Symposium

Antibiotics have been used to treat bacterial infections worldwide since their discovery in the early 20th century and are vital to human health. Unfortunately, the heavy use of antibiotics has led to the increased natural selection of antibiotic resistant bacteria. In urban rivers, the spread of resistance resistance is through through the direct acquisition of resistance genes by either either either cell-to -cell contact or DNA uptake via a process called horizontal gene transfer transfer(HGT) 2.HGT, resistance genes, and resistant bacteria are in greater abundance in wastewater systems, and are released into the environment in wastewater plant effluent2 ...

Exploring Molecular Simulations Of A Plausible Prebiotic Reduced Phospholipid Using Hyperchem Software, Lucas Leinen, N W. Fitch, K L. Even, Patrick Videau, Michael Gaylor

Faculty Research & Publications

How the first cells emerged from the primordial milieu is one of the great questions in science. Biomolecular emergence scenarios abound in the literature, but the lack of bioaccessible phosphate and molecular oxygen on the primordial Earth has posed formidable challenges for deducing emergence pathways. One idea gaining wide acceptance invokes delivery of the phosphide mineral schreibersite ((Fe,Ni)3P) to Earth via meteorite impacts ca. 4.2 billion years ago, whereupon they were corroded to reduced phosphorous oxyacids and phosphonates in primordial aquatic environments. We previously proposed that these reduced phosphorus forms could readily combine with putative geochemical species ...


Assisted Suicide, Valerie Ontiveros 2017 NebraskaCollege Preparatory Academy

Assisted Suicide, Valerie Ontiveros

Nebraska College Preparatory Academy Senior Capstone Projects

Assisted suicide is when a physician helps a terminally ill patient die without pain. As of right now, it is illegal in most states. Organizations about this issue were organized in the late 1930's (Humphry). According to Pro-Con. Org, 79% of patients requested assisted suicide even before they came terminally ill –if it got to that point.

Many states have different laws on assisted suicide. In no doubt, these patients go through a tremendous amount of pain and no one but themselves should decide when enough is enough. Technological advances have allowed this generation to help aid a person ...


Intervention To Enhance The Use Of Sit-Stand Desks In College Students, Ashley Raulli 2017 University of Iowa

Intervention To Enhance The Use Of Sit-Stand Desks In College Students, Ashley Raulli

Honors Theses at the University of Iowa

The purpose of this study is to test the effect an instructor-led activity break intervention on college students’ standing time, sitting time, physical comfort and alertness during class. The participants of this study were recruited from four sections of a course called Writing for Health and Human Physiology (HHP:3900). The class duration is 2.5 hours and is taught by the same instructor. Each student was exposed to two conditions: 1) access to sit-stand desks only; and 2) access to sit-stand desks plus instructor led activity breaks every 30 minutes. Sitting and standing behaviors were measured objectively throughout the ...


I. The High Strain Rate Response Of Hollow Sphere Steel Foam; Ii. The Dynamic Response Of An American Elm Tree, Ignacio Cetrangolo 2017 University of Massachusetts Amherst

I. The High Strain Rate Response Of Hollow Sphere Steel Foam; Ii. The Dynamic Response Of An American Elm Tree, Ignacio Cetrangolo

Masters Theses

PART I

Hollow-sphere (HS) steel foam is a relatively new material whose cellular morphology and material properties qualify it as a metallic foam. This is an innovative foam-like material that exhibits high stiffness paired with low relative densities. Technological advancements in the past few decades have enabled the manufacturing of this material by a sintering process and, as a result, research has begun to accelerate as a multi-school collaboration effort for this particular work. Even though commercialization has been a challenge for metallic foams, it is imperative that researchers continue to prove and promote the advantages of metallic foams despite ...


Attack And Defense Movements Involved In The Interaction Of Spodoptera Frugiperda And Helicoverpa Zea (Lepidoptera: Noctuidae), José P. F. Bentivenha, Edson L.L. Baldin, Débora G. Montezano, Thomas E. Hunt, Silvana L. Paula-Moraes 2017 University of Sao Paulo

Attack And Defense Movements Involved In The Interaction Of Spodoptera Frugiperda And Helicoverpa Zea (Lepidoptera: Noctuidae), José P. F. Bentivenha, Edson L.L. Baldin, Débora G. Montezano, Thomas E. Hunt, Silvana L. Paula-Moraes

Faculty Publications: Department of Entomology

The fall armyworm, Spodoptera frugiperda (J. E. Smith) and the corn earworm, Helicoverpa zea (Boddie) are among the main pests of maize. Both species exhibit cannibalistic behavior and quite often share the same feeding guild in maize (maize ears), which can result in several interspecific and intraspecific interactions. Paired interaction scenarios of intraspecific and interspecific larvae were assessed in arenas in the presence and absence of food to characterize movements resulting from interactions of these insects. There was a difference in the frequency of behavioral movements in all the interactions, except for S. frugiperda in the presence of food. Head ...

Associated Dataset: Climate Change Impacts On Southern Ross Sea Phytoplankton Composition, Productivity And Export, Daniel E. Kaufman, Marjorie A.M. Friedrichs, Walker O. Smith Jr., Eileen E. Hofmann, Michael S. Dinniman, John C.P. Hemmings

Data

This dataset includes data used in the publication Kaufman et al., 2017, JGR-Oceans, which investigates how these climatic changes in the Ross Sea, Antarctica, may alter phytoplankton composition, primary productivity and export. A one-dimensional version of the Model of Ecosystem Dynamics, nutrient Utilisation, Sequestration and Acidification was adapted for use in the Ross Sea (MEDUSA-RS). Glider measurements were used to force MEDUSA-RS, which includes diatoms and both solitary and colonial forms of Phaeocystis antarctica. Model performance was evaluated with glider observations, and experiments were conducted using projections of physical drivers for mid- and late-21st century. Additional scenarios examined the independent ...


Poison In Pink, Sydney V. Cook 2017 University of Montana, Missoula

Poison In Pink, Sydney V. Cook

Graduate Student Theses, Dissertations, & Professional Papers

Humans slather, spray, mist, and cleanse their bodies with personal care products like lotion, hairspray, cologne, and shampoo every day. Our cupboards are stocked full of them, but few of us understand what is in those jars and bottles. We trust that if it’s on the shelf at the store, it’s safe. However, this is not always the case, and many personal care products contain chemicals that are harmful to human and environmental health.

My multi-disciplinary Environmental Studies thesis project combines evidenced-based research, interviews, nonfiction narrative, and science communication to create part of a book manuscript intended to ...
