Southern Expansion Of The Brown Alga Colpomenia Peregrina Sauvageau (Scytosiphonales) In The Northwest Atlantic Ocean, Lindsay A. Green, Arthur C. Mathieson, Christopher D. Neefus, Hannah M. Traggis, Clinton J. Dawes

New Hampshire Agricultural Experiment Station Publications

Blackler first recorded Colpomenia peregrina in the Northwest Atlantic based on collections from Nova Scotia, Canada. Five decades later we found large quantities of C. peregrina in Maine, USA, even though it was absent during earlier floristic studies in this region. Thus, C. peregrina has undergone a rapid southern expansion along the Northwest Atlantic coast. While the causes of such an expansion are unknown, it could have a major effect on both shellfish cultivation and native seaweeds within New England because of competitive interactions and increased drag.

Lunar Radiation Environment And Space Weathering From The Cosmic Ray Telescope For The Effects Of Radiation (Crater), Nathan A. Schwadron, T. Baker, B. Blake, A. W. Case, J. F. Cooper, M. Golightly, Andrew P. Jordan, Colin J. Joyce, J. Kasper, K. Kozarev, J. Mislinski, J. Mazur, Harlan E. Spence

Physics & Astronomy

[1] The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) measures linear energy transfer by Galactic Cosmic Rays (GCRs) and Solar Energetic Particles (SEPs) on the Lunar Reconnaissance Orbiter (LRO) Mission in a circular, polar lunar orbit. GCR fluxes remain at the highest levels ever observed during the space age. One of the largest SEP events observed by CRaTER during the LRO mission occurred on June 7, 2011. We compare model predictions by the Earth-Moon-Mars Radiation Environment Module (EMMREM) for both dose rates from GCRs and SEPs during this event with results from CRaTER. We find agreement between these …

Accounting For Lesbian-Headed Families: Lesbian Mothers’ Responses To Discursive Challenges, Jody Koenig Kellas, Elizabeth A. Suter

Department of Communication Studies: Faculty Publications

Although lesbian mothers are often called to justify their family’s legitimacy, we know little about these interactions. The current study included 44 female coparents across 10 focus groups discussing the interactive process of discursive legitimacy challenges. Using the theoretical framework of remedial accounts (Schönbach, 1990), inductive and deductive coding revealed several existing and new types of challenges, accounting strategies, and evaluations relevant to interactions of lesbian mothers. Communicative processes unique to the interactions of female coparents included challenges emerging from societal master narratives (e.g., health care, education, politics, religion); accounting strategies such as leading by example; and evaluations related to …

Fetal Attraction: A Descriptive Study Of Patterns In Fetal Abductions, Kerry E. Arquette

Regis University Student Publications (comprehensive collection)

Fetal abduction is a crime in which a perpetrator forcibly takes an unborn baby from the womb of another woman. The act is always done without the permission of the pregnant woman, is always violent, and is often deadly for the mother or baby, or both. Based upon available data, the crime of fetal abduction is rare and relatively new, but publicized incidences in the United States of America are growing, which raises the question, "Why?" In order to answer that and other questions surrounding fetal abduction it is necessary to know more about the crime and the criminals. This …

The Use Of Familial Dna Searches: A Policy Analysis, Caroline O. Moorman

Regis University Student Publications (comprehensive collection)

Many cases go unsolved every day in the United States; some due to a lack of technological advancement in forensic science. When a person is killed, raped, or in danger of physical harm, it is the responsibility of law enforcement and their collaborative agencies to find and apprehend the responsible parties. The use of familial DNA searches in the United States is a relatively new investigative technique. Traditionally, DNA samples found at a crime scene are run through a national Combined DNA Index System (CODIS) to look for possible matches. When a sample does not return a positive hit, investigators …

Parenteral Nutrition Additive Shortages: The Short-Term, Long-Term And Potential Epigenetic Implications In Premature And Hospitalized Infants., Corrine K. Hanson, Melissa Thoene, Julie Wagner, Dean Collier, Kassandra Lecci, Ann Anderson-Berry

Journal Articles: Medical Nutrition

Nutrition support practitioners are currently dealing with shortages of parenteral nutrition micronutrients, including multivitamins (MVI), selenium and zinc. A recent survey from the American Society of Enteral and Parenteral Nutrition (ASPEN) indicates that this shortage is having a profound effect on clinical practice. A majority of respondents reported taking some aggressive measures to ration existing supplies. Most premature infants and many infants with congenital anomalies are dependent on parenteral nutrition for the first weeks of life to meet nutritional needs. Because of fragile health and poor reserves, they are uniquely susceptible to this problem. It should be understood that shortages …

Can You Hear Us Now? Investigating The Effects Of A Wireless Grid Social Radio Station On Collaboration And Communication In Fragile Populations, Sarah Anna Chauncey

School of Information Studies - Dissertations

The ability to interact with peers and coworkers in online digital networks is essential in learning and business environments. Our digital participatory culture is based on communication in response to purposeful activity and is facilitated by information and communication technologies (ICT). Students with emotional, behavioral, and learning disabilities are often disengaged and excluded from this knowledge-building conversation. This disengagement results in a cycle of failure exhibited through diminished self-efficacy and inadequate academic and emotional self-regulation. A critical goal of those who work with these students is to bolster their resilience, persistence, participatory, and communicative skills--to invite them back into the …

The Overlooked Role Of The National Environmental Policy Act In Protecting The Western Environment: Nepa In The Ninth Circuit, Michael C. Blumm, Keith Mosman

Washington Journal of Environmental Law & Policy

Critics widely disparage the National Environmental Policy Act (NEPA) for being a mere “paper tiger” or bureaucratic red-tape. The U.S. Supreme Court has surely encouraged this perception by treating the statute with consistent hostility, reducing it to a requirement only to follow prescribed administrative procedures but not produce any environmental results. But in the Ninth Circuit, NEPA lives a more important life, since that court has not forgotten NEPA’s essential environmental purpose. This article examines four lines of cases in the Ninth Circuit that may show that NEPA’s future might reflect its conservation purpose. These cases 1) deny NEPA plaintiffs …

Vol. 4 No. 1, Fall 2012; Beyond The Womb: An Argument For Fundamental Rights In Vaccination Exemption Law, Samantha Hardt

Northern Illinois Law Review Supplement

This Comment analyzes jurisprudence from the areas of abortion law and family autonomy rights, blending principles from both to suggest that a parent's right to decline vaccinations for his/her child should be deemed fundamental and, thus, should be statutorily protected by philosophical exemptions.

Marine Fungi Of U.S. Gulf Of Mexico Barrier Island Beaches: Biodiversity And Sampling Strategy, Allison Kathleen Walker

Dissertations

Marine fungi are an important but often overlooked component of marine ecosystems. Primarily saprotrophic, they are vital to coastal nutrient cycling processes and food webs. However, basic marine fungal distribution data are lacking in many parts of the world, as is knowledge of the sampling intensity required to characterize the biodiversity of these communities. The roles of substrate, season and latitude in shaping intertidal ascomycete community structure were examined for the U.S. Gulf of Mexico, and the role of sampling frequency on species richness estimates was also addressed. Best sampling practices were developed and 750 collections of beach detritus, sand …

Management Of Biological And Chemical Constituents For The Advancement Of Intensive, Minimal-Exchange, Biofloc-Based Shrimp (Litopenaeus Vannamei) Aquaculture, Andrew James Ray

Dissertations

Intensive, minimal-exchange, biofloc-based shrimp aquaculture systems may provide a sustainable alternative to traditional shrimp culture. Through a series of experiments, this document explores the effects of several key management strategies on water quality, isotopic distribution, and shrimp production.

An experiment evaluated the effects of managing suspended solids (biofloc) concentration at two levels. It was found that using a higher flow rate to larger settling chambers resulted in significantly lower biofloc and nitrate concentrations, and significantly improved shrimp growth rate. A second experiment compared systems with clear water and systems with biofloc. The filters in the clear water systems prevented biofloc …

Criminal Justice Students' Perceptions Of Restorative Justice: A Study Of Demographic Variables And Restorative Justice Values, Lana Adelaide Mcdowell

Dissertations

As time progresses, criminologists continue to search for philosophies and policies which possess the ability to reduce criminal behavior. One such philosophy and policy may be restorative justice. This study explores the meaning of restorative justice as well as types of restorative justice processes including peacemaking circles, group conferencing, reparative boards, victim offender mediation/reconciliation programs, victim offender panels, social justice initiatives, and community justice. This study also provides a tentative definition/theory of restorative justice which suggests crime creates broken relationships; therefore, reparation, inclusion, acceptance of responsibility, remorse, apology, forgiveness, resolution, reintegration, reconciliation, and restoration are necessary components of justice.

Mechanism Of Action And Gold Nanoparticle Delivery Of Pt(Iv) Prodrugs Of Cisplatin, Yi Shi

Chemistry - Dissertations

The antitumor effects of platinum(IV) complexes, considered prodrugs for cisplatin, are believed to be due to biological reduction of Pt(IV) to Pt(II), with the reduction products binding to DNA and other cellular targets. In this work we used pBR322 DNA to capture the products of reduction of oxoplatin, c,t,c-[PtCl₂(OH)₂(NH₃)₂], 2, and a carboxylate-modified analog, c,t,c-[PtCl₂(OH)(O₂CCH₂CH₂CO₂H)(NH₃)₂], 3, by ascorbic acid (AsA) or glutathione (GSH). Since carbonate plays a significant role in the speciation of platinum …

Molecular Mechanisms Regulating Neonatal Oocyte Survival And Primordial Follicle Formation In The Mouse Ovary, Robin L. Jones

Biology - Dissertations

In mammals, formation of the primordial follicle is a complex process involving the breakdown of germ cell cysts, where oocytes must separate from each other and subsequently become surrounded by somatic cells. As cysts separate, a large number of germ cells are lost by apoptosis, however the mechanisms by which cyst breakdown and germ cell death occur are not well understood. We first hypothesized that two anti-apoptotic regulators from the BCL2 family of proteins, BCL2 and MCL1, may be responsible for regulating neonatal oocyte survival. To elucidate the effects of BCL2 in the neonatal ovary, we examined ovaries of both …

Voltage Effects On Cells Cultured On Metallic Biomedical Implants, Seyed Morteza Haerihosseini

Biomedical and Chemical Engineering - Dissertations

Electrochemical voltage shifts in metallic biomedical implants occur in-vivo due to a number of processes including mechanically assisted corrosion. Surface potential of biomedical implants and excursions from resting open circuit potential (OCP), which is the voltage they attain while in contact with an electrolyte, can significantly change the interfacial properties of the metallic surfaces and alter the behavior of the surrounding cells, compromising the biocompatibility of metallic implants. Voltages can also be controlled to modulate cell function and fate. To date, the details of the physico-chemical phenomena and the role of different biomaterial parameters involved in the interaction between cells …

The Impact Of Standards-Based Reform On Special Education: An Exploration Of Westvale Elementary School, Jessica Kim Bacon

Teaching and Leadership - Dissertations

A critical, interpretivist, qualitative study, this project examines how standards-based reform impacts special education at an urban school, called Westvale Elementary School. The school was labeled a Persistently Low Achieving school under the No Child Left Behind Act and was thus required to undergo a "transformation" process. The demographics of the school at the time of the study were: over 95% free and reduced lunch, 40% Limited English Proficiency, and over 20% students with disabilities. The racial makeup of the school is: 50% Hispanic or Latino, 35% Black or African American, and 10% white. My methodological approach drew primarily upon …

PdmsStar-Peg Hydrogels Prepared Via Solvent-Induced Phase Separation (Sips) And Their Potential Utility As Tissue Engineering Scaffolds, B. M. Bailey, R. Fei, Dany J. Munoz Pinto, M. S. Hahn, M. A. Grunlan

Engineering Faculty Research

Inorganic-organic hydrogels based on methacrylated star polydimethylsiloxane (PDMS_star-MA) and diacrylated poly(ethylene glycol) (PEG-DA) macromers were prepared via solvent-induced phase separation (SIPS). The macromers were combined in a dichloromethane precursor solution and sequentially photopolymerized, dried and hydrated. The chemical and physical properties of the hydrogels were further tailored by varying the number average molecular weight (M_n) of PEG-DA (M_n = 3.4k and 6k g mol^-1) as well as the weight percent ratio of PDMS_star-MA (M_n = 7k g mol^-1) to PEG-DA from 0:100 to 20:80. Compared to analogous hydrogels …

Decision Making Under Interval Uncertainty (And Beyond), Vladik Kreinovich

Departmental Technical Reports (CS)

To make a decision, we must find out the user's preference, and help the user select an alternative which is the best -- according to these preferences. Traditional utility-based decision theory is based on a simplifying assumption that for each two alternatives, a user can always meaningfully decide which of them is preferable. In reality, often, when the alternatives are close, the user is often unable to select one of these alternatives. In this chapter, we show how we can extend the utility-based decision theory to such realistic (interval) cases.

Fusarium species are associated with diseases of corn, wheat, and soybean, causing significant yield loss in Nebraska. Some produce mycotoxins that are harmful to humans and animals.

Inference And Learning In Probabilistic Logic Programs With Continuous Random Variables, Muhammad Asiful Islam

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Statistical Relational Learning (SRL), an emerging area of Machine Learning, aims at modeling problems which exhibit complex relational structure as well as uncertainty. It uses a subset of first-order logic to represent relational properties, and graphical models to represent uncertainty. Probabilistic Logic Programming (PLP) is an interesting subfield of SRL. A key characteristic of PLP frameworks is that they are conservative extensions to non-probabilistic logic programs which have been widely used for knowledge representation. PLP frameworks extend traditional logic programming semantics to a distribution semantics, where the semantics of a probabilistic logic program is given in terms of a distribution …

In an effort to better understand the ancestral state of the human distal gut microbiome, we examine feces retrieved from archaeological contexts (coprolites). To accomplish this, we pyrosequenced the 16S rDNA V3 region from duplicate coprolite samples recovered from three archaeological sites, each representing a different depositional environment: Hinds Cave (~8000 years B.P.) in the southern United States, Caserones (1600 years B.P.) in northern Chile, and Rio Zape in northern Mexico (1400 years B.P.). Clustering algorithms grouped samples from the same site. Phyletic representation was more similar within sites than between them. A Bayesian approach to source-tracking was used to …

Factors Influencing The Spatial And Temporal Distrubtion Of Primary Productivity And Community Respiration In The Mississippi Coastal Estuarine Region, Ryan Anthony Vandermeulen

Master's Theses

This study describes the spatial and temporal distribution of net primary productivity (NetPP) and respiration (RESP) in relation to the biogeochemical, optical, and hydrographic variability in the Mississippi Sound and Mississippi Bight over the course of one year. Surface in-situ measurements of NetPP and RESP were regularly determined at two stations by a time-course detection of dissolved oxygen (DO) using novel optode technology. In addition, various biogeochemical, optical, and hydrographic parameters were examined over 14 stations throughout the estuary over a year, using ground and satellite (MODIS Aqua) measurements. In this study, consistently low dissolved inorganic N:P ratios (average N:P …

Seasonal Variations In The Inputs And Fate Of Mercury In A Northern Hardwood Forest, Xuying Wang

Civil and Environmental Engineering - Theses

The Adirondack region of New York is sensitive to atmospheric mercury deposition. In this study, the fate of mercury inputs to the Huntington Wildlife Forest (HWF) of the Adirondack region was examined by conducting a mercury mass budget over the annual cycle. Mercury cycling processes analyzed included wet mercury deposition, dry mercury deposition, foliar mercury accumulation, throughfall mercury, litterfall mercury, soil mercury evasion, and soil solution mercury fluxes. The mercury transport processes were quantified by integrating data collected from different sources in recent years (2004-2011) over a monthly time step. Dry mercury deposition (16.3 µg m-2 yr-1) was more important …
