- “I Have a Name Without a Title”; Representations of Middle Eastern Muslim Women in Western Literature.
- Creator
- Abed, Hadeel, Luria, Rachel, Harriet L. Wilkes Honors College, Florida Atlantic University
- Abstract/Description
-
Since September 11, 2001, novels about Middle Eastern Muslim women acclimating to Western society have been a popular genre for Western authors seeking to counter anti-Muslim prejudices. However, in their efforts to counteract Islamophobia, many of these authors perpetuate and reinforce harmful stereotypes, particularly regarding Middle Eastern Muslim women.

Show moreSince September 11, 2001, novels about Middle Eastern Muslim women acclimating to Western society have been a popular genre for Western authors seeking to counter anti-Muslim prejudices. However, in their efforts to counteract Islamophobia, many of these authors perpetuate and reinforce harmful stereotypes, particularly regarding Middle Eastern Muslim women. This thesis will explore two such works, Ten Things I Hate About Me by Australian author Randa Abdel-Fattah and A Large Expanse of Sea by Tahereh Mafi. I will argue that the novels have problematic components such as the "White Savior" archetype and how the characters reinforce stereotypical representations of their religion and culture, perpetuating assumptions that all or most Middle Eastern Muslim women are dissatisfied with their culture, appearance, and/or faith, which is not entirely representative of reality.

- SHOULD WE ALWAYS BE AIMING AT THE TRUTH? A LOOK INTO DEPRESSION.
- Creator
- Abellard, Bayard, Baima, Nicholas, Florida Atlantic University, Harriet L. Wilkes Honors College
- Abstract/Description
-
In this paper we attempt to understand how being truthful can bring people to experience depression. While it might cause depression, it also can bring people closer together than when being untruthful. Through this research we discover that realism can lead to depression and in some cases not lead to depression but a sense of bliss. I also review how optimism can lead to happiness and at the same time it can lead to depression due to not being able to reach the goals set out by one’s self....

Through this research we discover that realism can lead to depression and in some cases not lead to depression but a sense of bliss. I also review how optimism can lead to happiness and at the same time it can lead to depression due to not being able to reach the goals set out by one’s self. Overall, we discover that being truthful, in many cases, is the best option but at the same time there are cases where telling the truth would be more harmful than beneficial. Taken together, I believe it is best to always take your time to try and understand the situation before making a decision about whether telling the truth is ideal or not ideal.

Show moreAs medical research expands to include a vast variety of new treatments and the world becomes increasingly interconnected, the ethics involving patient care and treatment plan development also become extremely important to consider. One of the most novel and widely unexplored fields of reproductive health is oncofertility, a field of medicine that aims to minimize the negative impacts of cancer treatment on fertility. For many childhood cancer patients, cancer treatment involves oncofertility-related discussions that involve their families, physicians, and many other people. This paper serves primarily to evaluate the quality of educational and clinical resources available to childhood cancer patients regarding fertility preservation, the current approach to these cases from an ethical perspective, and to propose a procedure for treatment plan development and decision making that carefully considers the values and beliefs of the patient, his/her family members, physicians, and ethics board members involved with the case to help standardize the process.

- Para el sur: analyzing contemporary Mexican return migration with a case study of Jupiter, Florida immigrants.

- Adolfson, Dawn Fae, Corr, Rachel, Steigenga, Timothy J., Harriet L. Wilkes Honors College
- Abstract/Description

Recent data show that migration from Mexico to the United States has significantly decreased while return migration to Mexico has increased, producing a net reduction in the total number of Mexican migrants in the U.S. Some argue that the increase in immigration enforcement within the United States is the leading cause for this change because it has altered the cost/benefit balance enough to make migration less appealing and to encourage people to self-deport.

Show moreRecent data show that migration from Mexico to the United States has significantly decreased while return migration to Mexico has increased, producing a net reduction in the total number of Mexican migrants in the U.S. Some argue that the increase in immigration enforcement within the United States is the leading cause for this change because it has altered the cost/benefit balance enough to make migration less appealing and to encourage people to self-deport. The “self-deportation” hypothesis is based on the neo-classical theory of immigration. This case study offers an alternate explanation. Interviews with migrants in Jupiter, FL and returned migrants in Mexico suggest that the reasons for return are more complex. Family reunification, access to networks, and changing demographics are all important reasons driving the recent change in Mexican immigration. These findings suggest that the “self-deportation” approach to U.S. immigration policy may be misguided.

In this study, the concentration of butanone (also known as methyl ethyl ketone, MEK) in generic nail polish remover was detected with an analog gas chromatograph fitted with a thermal conductivity detector, and digitally converted for display on a Microsoft Excel worksheet using an mbed LPC 1768 microcontroller. A quantitative measure of butanone in the original sample was obtained through the method of standard addition with deionized water as the analyte, and was found to be 20%. This experiment is appropriate for a quantitative analysis, instrumental methods or possibly a general chemistry course, since students could gain experience with instrumental analysis and the concept of standard addition by using cheap and readily available materials.

Show moreThe practice of medicine is changing with the development of new Artificial Intelligence (AI) methods of machine learning. Coupled with rapid improvements in computer processing, these AI-based systems are already improving the accuracy and efficiency of diagnosis and treatment across various specializations. The increasing focus of AI in radiology has led to some experts suggesting that someday AI may even replace radiologists. These suggestions raise the question of whether AI-based systems will eventually replace physicians in some specializations or will augment the role of physicians without actually replacing them. To assess the impact on physicians this thesis seeks to better understand this technology and how it is transforming medicine. To that end this thesis researches the role of AI-based systems in performing medical work in specializations including radiology, pathology, ophthalmology, and cardiology. It concludes that AI-based systems will augment physicians and are unlikely to replace the traditional physician–patient relationship.

The current search for an efficient form of alternative energy has put a large focus on algal biofuels. This biofuel is very efficient, environmentally friendly, and acts as a virtually inexhaustible resource. The major issue with algal biofuel is its vast consumption of space to store the large amounts of algae necessary for fuel production.

This biofuel is very efficient, environmentally friendly, and acts as a virtually inexhaustible resource. The major issue with algal biofuel is its vast consumption of space to store the large amounts of algae necessary for fuel production. This is why scientists are trying to figure out ways to make algal storage units, photobioreactors, and the algae itself more efficient. In order to do so, the lipid metabolism of algae needs to be mapped. Using pre-existing maps of algal lipid metabolism, the lipid pathways of Chlamydomonas reinhardtii and its close relation Volvox carteri f. nagariensis were inspected. The key proteins KAR, HAD, EAR, and PP, had not yet been confirmed. Therefore, using preexisting metabolism maps, BLAST, and predicted protein sequences, the existence of these proteins in the aforementioned algae has been theoretically confirmed.

Dysfunction of GABAB-receptor (GABAB-R)-mediated synaptic transmission underlies various nervous system disorders including epilepsy, depression, schizophrenia, and addiction. Currently, only one GABAB-R orthosteric ligand is in clinical use. However, side effects such as sedation, tolerance, and motor impairment limit its use.

Show moreDysfunction of GABAB-receptor (GABAB-R)-mediated synaptic transmission underlies various nervous system disorders including epilepsy, depression, schizophrenia, and addiction. Currently, only one GABAB-R orthosteric ligand is in clinical use. However, side effects such as sedation, tolerance, and motor impairment limit its use. A dissociation of the therapeutic effects from the side effects may be achievable with drugs enhancing the endogenous physiological cellular response. The development of GABAB-R allosteric modulators has provided new modes of efficacy that may facilitate the development of novel therapeutic agents. In the present study, we investigated the effects of novel, newly synthesized GABAB-R allosteric ligands using a HEK-293 cell line stably expressing human GABAB1(b)/human GABAB(2) subunits using a cell-based cAMP HTRF assay. One compound was identified and characterized as a potential novel GABAB-R positive allosteric modulator (PAM), and will be subjected to further in vitro and in vivo analyses.

In this thesis I begin by introducing the Big Bang theory and discussing arguments for and against it. Then, I argue that the Big Bang Theory and the Biblical account of creation align in their descriptions of the origin of the universe. Thus, I ultimately argue that the Big Bang theory and the Biblical account of creation are not mutually exclusive.

Seawater has low Li ion concentrations, and has not been considered a profitable commercial source of this element. For my thesis work, I attempted to develop a mutant strain of the marine bacteria Photobacterium damselae subsp. damselae capable of sequestering lithium from seawater. I expose the bacteria to shortwave ultra violet (UV) light with the intent of obtaining a lithium dependent mutant. I was not successful at isolating such a mutant. However, I noted differences in colony size, between colonies grown in lithium media and sodium media, after UV treatment. Based on other research, the bacterial recovery methods of lithium and other metals from seawater remains a plausible option.

In Bermuda, there is no wastewater treatment plant; therefore, about 4.3x106 L per day of untreated sewage is released into the ocean through two marine outfalls. Water samples were collected from 12 sample sites (outfalls, offshore sites, and onshore beach sites near the outfalls) over 4 sampling events between August and October, 2013. Water samples were analyzed for the presence of Escherichia coli, Enterococcus sp., and Staphylococcus aureus. Antibiotic susceptibility of each purified isolate was tested and classified using Clinical and Laboratory Standards Institute standards. PCR analysis confirmed the presence of at least one methicillin-resistant S. aureus (MRSA) isolate. Documentation of antibiotic resistant bacteria in Bermudian waters supports the need for improved sewage treatment to ensure safe recreational use of these areas.

Show moreSleep deprivation (SD) is an extremely common problem worldwide. SD is correlated with various psychological and physiological consequences, such as mood instability or somatic pain, and it has also been linked to increased stress. While the relationship between stress and SD is well-studied, little is known about the neuronal mechanism underlying this relationship. Sleep-regulating (SL) pathways and stress-regulating (ST) pathways are both modulated by the circadian rhythm, and there are interactions between the two—some regions that contribute to sleep regulation also contribute to stress regulation. Sleep inhibits the activation of the HPA-axis, an ST system. SD results in a disruption in the SL systems, which subsequently disrupts ST systems. Three mechanisms underlying how SD leads to increased stress includes: 1. decreased inhibition of the HPA-axis, 2. ultradian rhythm dysregulation resulting in dysregulated stress response and 3. activation of other stress-responding regions.

- Abstract/Description

Kinesin motors bind to microtubules and function in mitosis and intracellular transport depending on the position of the motor domain within the primary sequence (Hirokawa and Noda 2008). KIF9 has recently been shown to be involved in MTOC positioning and mitotic entry in Dictyostelium (Tikhonenko et al. 2009). To determine if a similar role for KIF9 exists in mammalian cells, we are using siRNA-mediated knockdown of KIF9 in COS-7 cells. Analysis of unsynchronized and cell-cycle synchronized...

To determine if a similar role for KIF9 exists in mammalian cells, we are using siRNA-mediated knockdown of KIF9 in COS-7 cells. Analysis of unsynchronized and cell-cycle synchronized cells treated with siRNA to KIF9 reveal that the transition from G2 to M phase is delayed and that mitotic progression is also affected. Additionally, our data indicates that spindle pole function during anaphase may be abnormal in cells treated with siRNA, suggesting a role for KIF9 during that stage.

- Abstract/Description

Prostate cancer has the second highest mortality rate of all cancers in men. The Myc oncoprotein is misregulated in 70% of all cancers, including 70% of prostate cancers, and affects several cancer mechanisms. Myc is able to directly repress the expression of Tristetraprolin (TTP). TTP regulates mRNA stability by binding to select mRNAs. Furthermore, TTP is able to suppress Myc‐driven B cell lymphoma in mice. In these studies, cell culture models were used to access the role of Myc-induced...

The Myc oncoprotein is misregulated in 70% of all cancers, including 70% of prostate cancers, and affects several cancer mechanisms. Myc is able to directly repress the expression of Tristetraprolin (TTP). TTP regulates mRNA stability by binding to select mRNAs. Furthermore, TTP is able to suppress Myc‐driven B cell lymphoma in mice. In these studies, cell culture models were used to access the role of Myc-induced repression of TTP in prostate cancer. Prostate cancer cells lines were identified with inverse expression of Myc and TTP. Additionally, ARE‐containing genes with roles in various cancer mechanisms were differentially expressed in these models. These findings suggest that Myc’s ability to downregulate TTP is important in prostate cancer and provide new avenues for treating Myc‐driven prostate cancer.

Show moreLearning and memory studies in Drosophila melanogaster have led to advances in understanding fly and mammalian genetics and neurophysiology. Despite extensive studies, there remain gaps in the scientific literature concerning genes and neural pathways involved in learning and memory. There are differences in the memory traces between olfactory and visual memory, yet visual learning has not been studied to the same extent as olfactory learning. Visual place learning has only recently been addressed. We offer a new apparatus for studying visual place learning in D. melanogaster. The new apparatus offers a compelling and cost-effective approach to investigating visual place learning. The most notable difference between the new apparatus and others designed for visual place learning is the use of Peltier units in conjunction with a hydraulic system to supply heat used as a negative stimulus, with the advantages of even heat distribution, ease of construction, and ease of operation.

Show moreStudies of longevity and behavior have been facilitated by the genetically tractable model, Drosophila melanogaster (D. melanogaster). Disrupted circadian rhythms can be detrimental to health and lifespan by dysregulating the biological rhythms that guide behaviors such as sleeping and feeding. These stressors are associated with an increased risk for cancer and neurodegenerative diseases. Understanding how circadian biology is regulated by aging may inform novel interventions for age-related diseases. In this two-part study, we first characterize the lifespan of D. melanogaster under an extended light/dark cycle to determine whether dysregulated circadian rhythms affect longevity. The second study analyzes the effect of the longevity gene, methuselah (mth), on circadian periodicity. The mth mutant is a hypomorph with reduced mth expression, and flies harboring this mutation exhibit a ~35% prolonged lifespan. While the molecular mechanisms connecting aging and circadian biology remain unclear, our studies aim to understand if mth might influence the free-running clock and, if so, test whether this contributes to extended life. This study demonstrates how an extended light cycle can adversely affect longevity and the evidence that mth does not interfere with free-running clock rhythmicity.

In this project I measured the growth and atrazine degradation of P.ADP in media with atrazine as the sole nitrogen source. A mutant strain isolated after mutagenesis with UV light showed faster growth and reached higher densities than the control strain. A series of mating experiments were performed to determine whether the growth mutation was on the atrazine degrading plasmid or in the chromosome. The limitations and potential of P.ADP for atrazine degradation are discussed.

In aquatic environments, it is possible to extract eDNA from water samples, allowing for a variety of genetic tests to be performed, with great value in the fields of endangered species protection, invasive species control, and fisheries management among others. eDNA can persist in freshwater environments for many hours and can be attributed to fish up to one kilometer upstream from the collection site. However, water conditions in marine environments may reduce the survivability of eDNA. I evaluated the reliability eDNA analysis in the marine environment by analyzing water samples taken immediately before a survey of the common snook, Centropomus undecimalis, an important game fish. The eDNA sampling method was successful at detecting snook presence in the Indian River Lagoon, although with some practical limitations.

Other studies conclude that a defendant’s race will be a factor in determining whether or not they are sentenced to capital punishment. Despite the evident racial discrimination that plagues capital cases, Ernest van den Haag contends that “unequal justice is still justice” and that if someone is guilty of a capital offense, they don’t deserve any less punishment simply because the death penalty is applied disproportionately based on race. I argue, against van den Haag, that unequal justice violates defendants’ rights to due process. Even if a defendant is guilty, justice demands a fair system that protects defendants from systemic injustice and treats all victims and defendants equally.
