Standing's Expected Value, Jonathan R. Nash

Faculty Articles

This Article argues in favor of standing based on expected value of harm. Standing doctrine has been constructed in a way that is oblivious to the idea of expected value. If people have suffered a loss with a positive ex­pected value, they have suffered an "injury in fact." The incorporation of expected value into standing doctrine casts doubt on many of the Supreme Court's decisions in which it denies standing because the relevant injury is too "speculative" or is not "likely" to be redressed by a decree in the plaintiff's favor. This Article addresses this shortcoming in standing juris­prudence by …

The Carcinogenic Effects Of Aspartame, Devora Sara Gelbfish

The Science Journal of the Lander College of Arts and Sciences

Aspartame, one of the most common artificial sweeteners, is used as a food additive worldwide. Because of early experimentation with rats linking aspartame to higher risk of cancer, there is much concern regarding the safety of aspartame. However, analytical review and numerous subsequent studies have disproven previous experimentation and reaffirmed that aspartame consumption in humans does not increase the risk of cancers. At the current time there is no credible evidence to support the idea that aspartame is carcinogenic. The evidence confirms that at current levels of consumption aspartame is a safe alternative to sucrose.

The Scientific Evidence Validating The Use Of Honey As A Medicinal Agent, Raitzel Chemda Bernstein

The Science Journal of the Lander College of Arts and Sciences

Honey has been used to treat wounds, infections, and other diseases since ancient times. Due to the widespread bacterial resistance to antibiotics, scientists have investigated the healing power of honey. Numerous studies have documented the broad-spectrum antibacterial effect of honey and its success in inhibiting MRSA. The use of honey as a wound dressing has proven to successfully heal chronic wounds in short amounts of time by inhibiting pathogens, reducing inflammation, rebuilding damaged tissue, and minimizing scarring. The mechanisms of action are directly related to the high hydrogen peroxide and rich polyphenol content present in honey. These two components account …

Computational Analysis And Prediction Of Genome-Wide Protein Targeting Signals And Localization, Jhih-Rong Lin

Theses and Dissertations

Computational prediction of protein subcellular localization can greatly help to elucidate its functions. Despite the existence of dozens of protein localization prediction algorithms, the prediction accuracy and coverage are still low. Several ensemble algorithms have been proposed to improve the prediction performance, which usually include as many as 10 or more individual localization algorithms. However, their performance is still limited by the running complexity and redundancy among individual prediction algorithms. In the first part of the dissertation, we propose a novel method for rational design of minimalist ensemble algorithms for practical genome-wide protein subcellular localization prediction. The algorithm is based …

Role Of Microrna-155 In A Mouse Model Of Colon Cancer., Claire Mitchell Midyette

Theses and Dissertations

Colorectal cancer remains the third most common malignancy and the fourth most common cause of cancer mortality worldwide. Dysregulated miRNA levels are associated with several types of malignancies and may serve as important biomarkers and/or therapeutic targets in colorectal cancer. We examined the role of miRNA-155 on tumorigenesis and associated symptoms using a well-characterized mouse model of colorectal cancer. C57BL/6 wild-type mice and miRNA-155-/- mice (n=7-13 group) were given a single injection of AOM (10mg/Kg) followed by 3 cycles of DSS (2% in the water for 1 week followed by 2 weeks of plain water). A C57BL/6 wild-type group that …

When Autonomous Vehicles Take Over The Road: Rethinking The Expansion Of The Fourth Amendment In A Technology-Driven World, Rachael Roseman

Richmond Journal of Law & Technology

On a cool summer morning in upstate New York, a man sitting on his couch types in the coordinates to a warehouse in Virginia on his phone and presses “engage.” At that moment, the engine of a vehicle several miles away starts up, and the vehicle slowly backs out of the driveway. Without a driver or any occupants, the vehicle travels several hundred miles from the driveway in New York to the warehouse in Virginia. Meanwhile, the man who engaged the vehicle remains seated on his couch in upstate New York. The man has engaged an autonomous vehicle (AV), capable …

International Polar Year (Ipy) Back To The Future (Btf): Changes In Arctic Ecosystem Structure Over Decadal Times Scales, Sandra Villarreal

Open Access Theses & Dissertations

Arctic vegetation communities are responding to climate warming through shifts in species composition and diversity but most observations have been made over relatively short time frames, and/or in association with experimental manipulations. Because vegetation plays a key role in regulating ecosystem productivity, nutrient cycling, surface energy budgets, and trophic interactions in the Arctic, there is a need to better understand shifts in tundra vegetation communities over decadal time scales. Understanding these shifts and their impact on ecosystem structure and function in the Arctic has important implications for predicting the future state of both the Arctic and the Earth System. Long …

Does Fertility Status Influence Impulsivity And Risk Taking In Human Females? Adaptive Influences On Intertemporal Choice And Risky Decision Making, Farnaz Kaighobadi,, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

Informed by the research on adaptive decision making in other animal species, this study investigated human females’ intertemporal and risky choices across the ovulatory cycle. We tested the hypothesis that at peak fertility, women who are exposed to environments that signal availability of higher quality mates (by viewing images of attractive males), become more impulsive and risk-seeking in economic decision tasks. To test this, we collected intertemporal and risky choice measures before and after exposure to images of either attractive males or neutral landscapes both at peak and low fertility conditions. The results showed an interaction between women’s fertility status …

When Will We Meet Again? Regularities Of Social Connectivity As Reflected In Memory And Decision Making, Thorsten Pachur, Lael J. Schooler, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

In 1967, the social psychologist Stanley Milgram reported a fascinating observation. For a study on social connectivity, he randomly picked several individuals in Wichita, Kansas, and asked them to get a message delivered to a particular target person in Cambridge, Massachusetts—a distance of more than 1,300 miles. There were two catches. First, Milgram provided no address but only the name and some basic information about the target person, such as the area where he lived and his profession (the target person was the same for everybody). Second, people could only forward the message to someone they knew on a firstname …

The Bounds Of Rationality And Cognitive Building Blocks, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

In 1956, Herbert Simon scolded researchers using economic theory to characterize rational choice, admonishing that “organisms … do not, in general, ‘optimize’ ” (p. 129). Simon rejected the notion that decision makers met the god-like qualifications required of rational agents. Instead, he proposed that, to fully understand decision making, one must study two critical components: the cognitive capacities of the organism and the structure of the environment in which an organism operates (Simon 1956).

Despite the clear relevance of Simon’s ideas to the study of animal behavior, few have appreciated his contribution (but see Callebaut 2007). The role of the …

Olanzapine Sensitization And Clozapine Tolerance: From Adolescence To Adulthood In The Conditioned Avoidance Response Model, Jing Qiao, Hong Li, Ming Li

Department of Psychology: Faculty Publications

Disruption of conditioned avoidance response (CAR) in rodents is one trademark feature of many antipsychotic drugs. In adult rats, repeated olanzapine (OLZ) treatment causes an enhanced disruption of avoidance response (sensitization), whereas repeated clozapine (CLZ) treatment causes a decreased disruption (tolerance). The present study addressed (1) whether OLZ sensitization and CLZ tolerance can be induced in adolescent rats, and (2) the extent to which OLZ sensitization and CLZ tolerance induced in adolescence persists into adulthood. Male adolescent Sprague–Dawley rats (approximate postnatal days (BP) 43–47) were first treated with OLZ (1.0 or 2.0 mg/kg, subcutaneously (sc)) or CLZ (10 or 20 …

Avoidance Disruptive Effect Of Clozapine And Olanzapine Is Potentiated By Increasing The Test Trials: Further Test Of The Motivational Salience Hypothesis, Min Feng, Nan Sui, Ming Li

Department of Psychology: Faculty Publications

Antipsychotic drugs suppress animals’ ability to avoid an aversive stimulus in the conditioned avoidance response model (CAR). This behavioral effect is thought to reflect antipsychotic activity and is suggested to be mediated by a drug’s action in attenuating the motivational salience of a conditioned stimulus (CS). In the present study, we tested whether atypical antipsychotic drugs clozapine and olanzapine act through this behavioral mechanism by manipulating the number of avoidance test trials. We reasoned that more CS trials in the present of clozapine or olanzapine would afford the drug more opportunities to decrease the motivational salience of the CS, thus …

Interoceptive Conditioning In Rats: Effects Of Using A Single Training Dose Or A Set Of 5 Different Doses Of Nicotine, Steven T. Pittenger, Rick A. Bevins

Department of Psychology: Faculty Publications

Interoceptive conditioning contributes to the tenacity of nicotine dependence. Previous research investigating nicotine as an interoceptive stimulus has typically employed administration of a single training dose of nicotine over an extended time. This approach has allowed for careful study of the nicotine stimulus. In humans, the nicotine stimulus is unlikely to be fixed across learning episodes. Thus, from a translational perspective, systematic variation of nicotine dose in training might better approximate interoceptive conditioning in humans. Notably, training with a class or set of discrete exteroceptive stimuli (e.g., different pictures of cars) produces interesting behavioral differences relative to training with a …

How Do Shellfisheries Influence Genetic Connectivity In Metapopulations? A Modeling Study Examining The Role Of Lower Size Limits In Oyster Fisheries, Daphne M. Munroe, Eileen E. Hofmann, Eric N. Powell, John M. Klinck

CCPO Publications

Fisheries can potentially alter evolutionary processes such as genetic connectivity and lead to genotypic changes in stocks. Using an individual-based metapopulation genetics model, we examined the possible influence of oyster (Crassostrea virginica) fisheries on genetic connectivity. We simulated a range of realistic fishing pressures, with and without a minimum size limit (limit = 63.5 mm), over a range of fishing scenarios including single-area and stock-wide fisheries. Movement of a neutral marker gene provided an indicator of gene transfer between populations. Simulations showed that fishing may alter genetic connectivity. Increasing fishing pressure tended to decrease potential for fished populations …

Realizing The Potential Of The Principled Approach To Evidence, Lisa Dufraimont

Articles & Book Chapters

Ron Delisle's concern that lawyers and judges be constantly mindful of the purposes and policies underlying the rules of evidence led him to become one of the pioneers of the principled approach to evidence. This paper seeks to evaluate the extent to which the efforts of Canadian courts to incorporate principles into evidence law have alleviated the problem of the complexity of the traditional rules. Evidentiary rules are complex because they are dense or technical. Evidentiary principles are more capable of flexible and contextual application than evidentiary rules, but principles too are complex in the sense that they are less …

Speech applications are currently used successfully in many contexts in which the auditory modality allows users to accomplish tasks efficiently and effectively, such as the automation of banking services normally handled by live agents. Such technology is also increasingly being utilized for language education to teach various aspects of the target language. However, though games are routinely played in language classrooms to help students practice elements of spoken language such as pronunciation and conversational skills, educational speech game software is still not widely available. This project explores technical issues involved in adapting some of these classroom games for inclusion in …

Smit: Local System Administration Across Disparate Environments Utilizing The Cloud, Kevin Guyot

Technical Library

System administration can be tedious. Most IT departments maintain several (if not several hundred) computers, each of which requires periodic housecleaning: updating of software, clearing of log files, removing old cache files, etc. Compounding the problem is the computing environment itself. Because of the distributed nature of these computers, system administration time is often consumed in repetitive tasks that should be automated. Although current system administration tools exist, they are often centralized, unscalable, unintuitive, or inflexible. To meet the needs of system administrators and IT professionals, we developed the Script Management Tool (SMiT). SMiT is a web-based tool that permits …

You Get What You Deserve : The Relationship Between Injustice And The Consequences Of Social Exclusion, Heather A. Pease

UNF Graduate Theses and Dissertations

In this current research I sought to answer two questions; 1) Do individuals have the capacity to recognize when they are being justly or unjustly socially excluded or conversely socially included? 2) Do the consequences of just and unjust social exclusion or social inclusion vary? In efforts to address these questions, I used perceptions of burden (i.e., participant’s overall contribution to a group task) to manipulate the perceived fairness of one’s inclusionary status to see how this affects the participants’ emotional and behavioral reactions.

In Study 1, participants engaged in an imaginary group interaction in which they were burdensome (performing …

Plant-Pathogen Interactions Associated With Wasting Disease In The Tropical Seagrass Thalassia Testudinum., Kyle Loucks

UNF Graduate Theses and Dissertations

Lipopolysaccharide (LPS) was shown to serve as a strong elicitor of the early defense response in the subtropical seagrass Thalassia testudinum Banks ex König and was capable of inducing an oxidative burst identified at the single cell level. The formation of reactive oxygen species (ROS) included a diphenylene iodonium sensitive response, suggesting the involvement of an NADPH oxidase. A 900 bp fragment of this enzyme was sequenced and found to encode a NAD binding pocket domain with extensive homology to the Arabidopsis thaliana rbohF (respiratory burst oxidase homolog) gene. Pharmacological dissection of the early events preceding ROS emission revealed that …

Response Of The Epiphytic Algal Communities To Experimentally Elevated Nutrient Levels In Intertidal Salt Marsh Habitats, Stephanie Verhulst

UNF Graduate Theses and Dissertations

Epiphytes are organisms attached to plants and are responsible for the majority of primary productivity in many aquatic systems. While epiphytes serve as a valuable food resource to herbivores, they may prove deleterious to the host plant by competing for light and nutrients, as well as increasing sheer stress. This study evaluated the impacts of nutrient additions, nitrogen and phosphorus, on the epiphytic algal community on Spartina alterniflora over the course of two growing seasons. Three nutrient treatments (N, P, and N+P) and one control treatment were placed in a salt marsh in the Tolomato River during the growing seasons …

Bacteriostatic Effects Of Sucralose On Environmental Bacteria, Arthur Phillip Omran Jr.

UNF Graduate Theses and Dissertations

Sucralose is a zero calorie sweetener developed and manufactured by Tate and Lyle Sweetener Company in the 1980’s. They sell the sweetener compounded with maltodextrin and dextrose under the brand name Splenda®. Sucralose was developed as a low cost artificial sweetener that is non-metabolizable in humans and can withstand changes in pH and temperature. It is not degraded by the waste water treatment process. Since the molecule can withstand heat, acidification and microbial degradation it is accumulating in the environment, and has been found in waste water, estuaries, rivers and the Gulf Stream. The highest concentration of environmental sucralose detected …

Comparative Sugar Transport By Crustacean Hepatopancreas And Intestine, Ada Duka

UNF Graduate Theses and Dissertations

Glucose is transported in crustacean hepatopancreas and intestine by Na⁺-dependent co-transport, while Na⁺-dependent D-fructose influx has only been described for the hepatopancreas. It is still unclear if the two sugars are independently transported by two distinct cotransporter carrier systems. In this study lobster (Homarus americanus) hepatopancreas brush border membrane vesicles (BBMV) were used to characterize, in detail, the cation-dependency of both D-[³H] glucose and D-[³H] fructose influxes, while in vitro perfused intestines were employed to determine the nature of cation-dependent sugar transport in this organ. Over the sodium concentration range …

The Effects Of Multiple Abiotic Stressors On The Susceptibility Of The Seagrass Thalassia Testudinum To Labyrinthula Sp., The Causative Agent Of Wasting Disease, Nichole Danielle Bishop

UNF Graduate Theses and Dissertations

In the past century, seagrasses have experienced massive die off episodes in what has been collectively referred to as “wasting disease.” Researchers generally agree that wasting disease is caused by a protist of the Labyrinthula genus, and that environmental stressors can make some populations of seagrasses more susceptible to infection. The purpose of this study was to examine the combined effects of elevated salinity, elevated temperature, elevated sulfide and night-time hypoxia on Thalassia testudinum health and its response to Labyrinthula sp. infection under controlled conditions. To test these effects, microcosms were utilized and individual seagrass shoots were randomly assigned to …

A Survey Of The Taxonomy Of The Cyanobacteria From Northeast Florida, Descriptions Of Novel Taxa, And An Investigation Into The Factors Which Influence The Epibenthic Cyanobacterial Community, Holly Stephanie Stocks

UNF Graduate Theses and Dissertations

Cyanobacteria are important components of the aquatic system, valued for their oxygen production, nitrogen fixation, and as the base of many aquatic food webs. This study investigated several aspects of cyanobacteria such as the diversity and response to nutrient enrichments. A survey of Northeast Florida was conducted between the years of 2010 and 2012; a total of 145 taxa were identified in freshwater habitats, such as springs, lakes, rivers, and retention ponds. While surveying the St. Johns River in Jacksonville, Florida, a novel Stigonematalean taxon was isolated and cultured. Subsequent morphological and genetic analyses indicate that this taxon is related …
