Description
Bacteria play a vital role in the world ecosystem, more importantly human health and disease. The capability to differentiate and identify these microorganisms serves as an important research objective. In past years, separations-based approaches have served as a way to observe and identify bacteria based on their characteristics. Gradient insulator dielectrophoresis (g-iDEP) provides benefits in identifying serotypes of a single species with precise separation. Separation of Staphylococcus epidermidis in a single g-iDEP microchannel is conducted exploiting their electrophoretic and electrokinetic properties. The cells were captured and concentrated at gates with interacting forces within the microchannel to clearly distinguish between the two strains. These results provide support for g-iDEP serving as a separating method and, furthermore, future clinical applications.

Description
In the United States, many new cases of type I diabetes appear among youth. Upon diagnosis, many patients experience psychosocial issues in addition to physical issues, including depression, anxiety, and poor self-esteem. Diabetes educators have found that it is important to form interpersonal connections and trust with their adolescent patients. One tool that may be particularly useful for diabetes educators to implement is art therapy, which combines creativity and problem solving in a practical manner. Art therapy may be particularly helpful for individuals with type 1 diabetes because of the great cognitive and emotional changes, which occur during adolescence. In order for caretakers and educators to implement tenants of art therapy, it is helpful to have a medium, such as an art journal, which provides a foundation on which to process the emotions and thoughts the adolescent is experiencing as they process diabetes and their feelings throughout diagnosis. Keywords: art therapy, type I diabetes

Description
Republican ideals influenced George Washington during his tenure as the Commander-in-Chief of the Continental Army and as president of the United States. These ideals included: virtue, reputation (which was the mark of a true 18th century gentleman), and encouraging individual citizens to perform their civic duties to safeguard their liberties. While there exist some instances where Washington had to put the good over the country over republicanism, it was done to further republicanism in the long run. Washington valued his reputation which compensated for his lack of a formal education. While not formally educated, Washington did receive more beneficial education by surveying the Ohio Country; an education which led him to his generalship and ultimately, the presidency.

Description
This thesis investigates the role of colorism and the practice of skin whitening for women in China. By analyzing the historical evolution of ideal skin beauty in China, this project found that the cultural fixation with women's skin tone was used as a sociopolitical tool to regulate women's agency. Furthermore, this thesis also examines current skin whitening advertisements to understand modern impacts of Westernization and consumerism on contemporary discourses of femininity and beauty. Finally, it concludes with a discussion on skin whitening's ability to empower but also subjugate women within the confines of patriarchal expectations.

Description
Revenge porn is the accepted term used to describe the distribution of explicit photos online with the intent to incite embarrassment or shame. Perpetrators are typically ex-lovers seeking revenge on a former partner. This harassment has become widespread alongside increased access to online networks and "sexting" culture. Early studies indicate revenge porn reflects a larger cultural attitude of "slut shaming", the tendency to shame women for behaving in a sexual manner outside the boundaries of traditional female sexuality. Focus groups were organized to discuss views regarding revenge porn, Internet privacy, and legislature.

International adoption is always changing, influenced by global politics and social norms. This thesis looks specifically at Russian and Eastern European adoption and reasons why parents choose these countries from which to adopt. I then interviewed eight people who had either adopted or been adopted from this region to examine the idea of "culture-keeping" and what factors influence a parent's decision to encourage culture-keeping or not.

Description
What characteristics do people prefer in potential mates? Previous studies have explored this question, discovering that preferred characteristics vary by people's sex and sexual strategy, but have implied that these preferences remain constant across the lifespan. We suggest, however, that systematic variation exists in individuals' mate preferences across the lifespan, as they shift their investments from mating toward parenting. We suggest that the characteristics of a potential mate can be viewed as affordances that assist or hinder an individual in achieving certain fundamental goals. Incorporating the framework of Life History Theory with this affordance-management approach to social behavior, we propose that an individual's life stage, sex, and life history strategy together serve as the basis for these goals and thereby shape the characteristics people seek in potential mates. Using data collected from participants aged 18-45 recruited on Amazon's Mechanical Turk, we tested a range of hypotheses derived from our approach. In general, results provide mixed support for a role of life stage in shaping mate preferences. For example, nurturance and social competence were viewed as more necessary characteristics in a mate by participants invested in parenting. Moreover, as their investment in mating increased, females expressed a greater preference for ambition in their potential mates, but males did not. Other predictions were not borne out, however, suggesting that there is still much to be learned from investigating the relationship between life stage and mate preferences.

Description
Morbid obesity is associated with cardiovascular and metabolic disorders. A major contributor to the pathogenesis of these diseases is impaired vasodilation resulting from elevated reactive oxygen species (ROS). This is because certain ROS such as superoxide are raised with obesity and scavenge the endogenous vasorelaxant nitric oxide, resulting in hypertension. The objective of this study was to measure the ability of genistein to quench superoxide in the vasculature of ob/ob mice, an animal model of obesity and type 2 diabetes. Genistein is an isoflavonic phytoestrogen naturally found in soy products. While genistein has documented antioxidant and anti-inflammatory properties, it is not known whether this protects the vasculature from oxidative stress. Genistein was hypothesized to reduce superoxide in arteries from female ob/ob mice. The superoxide indicator dihydroethidium (DHE) [2µL/mL HEPES buffer] was added to isolated aortae and mesenteric arteries from mice fed either a control (standard rodent chow containing 200-300 mg genistein/kg) or genistein-enriched (600mg genistein/kg rodent chow) diets for 4 weeks. Frozen tissues sections were collected onto glass microscope slides and examined using confocal microscopy. Contrary to the hypothesis, a diet containing twice the amount of genistein found in standard chow did not significantly reduce superoxide concentrations in aortae (p=0.287) or mesenteric arteries (p=0.352). Superoxide dismutase, an antioxidant enzyme that breaks down superoxide, was significantly upregulated in the genistein-enriched diet group (p=0.004), although this elevation did not promote the breakdown of superoxide. In addition, the inflammatory marker iNOS was not downregulated in the genistein-enriched diet group (p>0.05). The results indicate that high amounts of isoflavones, like genistein, may not exhibit the purported antioxidant effects in the vasculature of obese or diabetic subjects. Further studies examining arteries from ob/ob mice fed a genistein-free diet are needed to elucidate the true effects of genistein on oxidative stress.

Description
The purpose of this paper is to evaluate the effectiveness of a craft book used for stimulation therapy on the phonetic sounds /ŋ/, /r/, /s/, /ʃ/, /tʃ/, and /θ/. The book is specifically geared toward children who do not qualify for speech remediation services but who may be at risk of a speech sound disorder. Four children participated in the study with ages ranging from 4;3-7;6. The study lasted for four weeks in which data was collected on a weekly basis via Likert Scale surveys in accordance with two conversational speech samples. The speech samples were phonetically transcribed with minimal differences pre and post use of the craft book. Data from the surveys give insight to the children’s favorite crafts, the level of difficulty of each craft, and the likelihood of the craft book to be used as part of a remediation program. The study had limitations in sample size, duration, and number of craft activities. Future revisions should include increasing the number of crafts available per chapter and incorporating into the introduction an educational component for parents.

Description
Introspective awareness refers to direct access to one’s own internal and subjective thoughts and feelings (Wimmer & Hartl, 1991). Two theories, simulation theory and theory-theory, have been used to understand our access to our mental states. Simulation theory (Harris, 1991) involves imagining yourself in another person’s situation, reading off of your mental state, and attributing that state to the other person. Theory-theory (Gopnik, 1993) involves an interrelated body of knowledge, based on core mental-state constructs, including beliefs and desires, that may be applied to everyone—self and others (Gopnik & Wellman, 1994). Introspection is taken for granted by simulation theory, and explicitly denied by theory-theory. This study is designed to test for evidence of introspection in young children using simple perception and knowledge task. The current evidence is against introspective awareness in children because the data suggest that children cannot report their own false beliefs and they cannot report their on-going thoughts (Flavell, Green & Flavell, 1993; Gopnik & Astington, 1988). The hypothesis in this study states that children will perform better on Self tasks compared to Other tasks, which will be evidence for introspection. The Other-Perception tasks require children to calculate the other’s line of sight and determine if there is something obscuring his or her vision. The Other-Knowledge tasks require children to reason that the other’s previous looking inside a box means that he or she will know what is inside the box when it is closed. The corresponding Self tasks could be answered either by using the same reasoning for the self or by introspection to determine what it is they see and do not see, and know and do not know. Children performing better on Self tasks compared to Other tasks will be an indication of introspection. Tests included Yes/No and Forced Choice questions, which was initially to ensure that the results will not be caused by a feature of a single method of questioning. I realized belatedly, however, that Forced Choice was not a valid measure of introspection as children could introspect in both the Self and Other conditions. I also expect to replicate previous findings that reasoning about Perception is easier for children than reasoning about Knowledge.
