Description
For many years now, early word learning in children has been an important subject among many researchers. There are many ways in which children learn word-object pairings including using co-occurrences, forwards integration, and backwards integration. This study primarily focuses on backwards integration. Backwards integration entails using learned information to be able to recall a word-object pairing from a previous time. In this thesis, three different studies were conducted with children aged 3-7 years old. In the general task, children were presented with a computerized word-learning task in which they could track word-referent pairings using co-occurrence statistics, forward integration, and backward integration. The goal of Study 1 and Study 2 was to determine the best task design to study backwards integration. The goal of the final study, Study 3, was to provide preliminary data on backwards integration. The overall results indicate that a between subjects design is the most beneficial way to test backwards integration because as a group, children were learning when compared to chance. In addition, the results from Study 3 showed that children were not learning in the task. In general, this suggests that this task may have been very difficult for children to complete. One limitation of Study 3
was that there was a small sample size of only 29 children. In order to account for this, the sample sizes in Study 2 and Study 3 were combined. This combined data did show that children succeeded at the backwards integration condition. It is noteworthy to mention that backwards integration was above chance in Study 2 and in the Study 2 and 3 combination. Therefore, the overall results suggest that children may possibly be able to backwards integrate; however, no evidence of learning in any of the other conditions were present.

Description
This paper explores the importance of teacher preparation and quality as evidenced by three of the top-performing countries, Canada, Finland, and Singapore, on the 2015 Programme for International Students Assessment (PISA). All three of these countries have exemplary teacher preparation programs that are consistent nationwide with rigorous entry requirements, a demanding course load, and numerous opportunities to gain in-field experience. They also all compensate their teachers at a comparable salary to that of other occupations to incentivize more people to enter the field. In the United States, on the other hand, society devalues teachers, teachers are not paid what they deserve, and there is a lack of consistency in teacher preparation programs, specifically in regards to out-of-field teaching and the alternate ways people can become certified. These two issues have plagued America's educational system, and they have resulted in under-prepared teachers and lower-performing students. Not only is there inconsistency in the way that teachers enter into the profession, but teacher preparation programs themselves vary in their requirements. In order to improve its educational system, America must obtain more rigorous teacher preparation programs, increase teacher salary, provide prospective teachers with more classroom experience, and have specific admission requirements to be a part of the teaching profession. There is much that the United States can learn from the 2015 PISA results and the many successful educational systems around the world, and it is time that America pays attention to the wealth of international educational research available to better its teacher preparation programs and obtain more quality teachers.

Description
The purpose of this study was to investigate differences in word learning ability when assessing phonological and semantic representations in elementary-age children with typical development. Methods: The study included 116 2nd graders and 25 6th graders who were tested using the Assessment Battery for Children - Word Learning. Children played virtual pirate games that tested their ability to store, retrieve, and recall phonological and semantic representations of nonwords. Results: Based on effect sizes, the largest differences in word learning ability occurred for tasks requiring phonological working memory. Overall, 6th graders had higher performance means in all aspects of word learning. Both groups performed better on tasks that required less phonological or semantic detail. Discussion: Findings align with previous research reporting that as children develop, their capacity to store, retrieve, and recall phonological information increases as a result of increased phonological loop capacity and rehearsal speed. Similarly, as children age they perform better on tasks requiring visuospatial working memory such as storing and recreating the semantic representations of new words. These findings have implications for the word learning process in children with typical development.

Description
Token economies are a type of behavioral reinforcement that are particularly useful in classroom settings for increasing student compliance, for both typically developing children and children with autism spectrum disorder. During this study, we implemented a token economy in an inclusive preschool classroom with tokens contingent on compliance to classroom rules. Three participants, two with a diagnosis of autism spectrum disorder and one considered typically developing, were included in the study. Results indicated that levels of compliance increased for both the typically developing participant and participants with autism, and did not drop below baseline levels during the withdrawal phase, suggesting there was no lack of intrinsic motivation. Further, the typically developing participant and one of the participants with autism spectrum disorder had very similar levels of compliance, while the other participant had much higher levels of compliance throughout every phase, suggesting that the compliance levels for peers with more advanced repertoires with autism may differ from both typically developing peers and peers who have less developed repertoires. The implications of these results are discussed as they relate to compliance from an ABA perspective.

Description
Within our current educational infrastructure, there’s a lack of substantial preventive care knowledge present among elementary schoolchildren. With education cuts occurring statewide, many schools are left impoverished and schools are incapable of implementing various programs to benefit their local communities. This endeavor aims to visit public and charter elementary schools in the Phoenix Valley to educate youth regarding easily avoidable health risks by implementing healthy eating habits and exercise. Project BandAid will immerse students ages 7-9 in hands-on activities to enhance their knowledge on hygiene, healthy eating habits, and safety. This project incorporated funding from the Woodside Community Action Grant and Barrett, the Honors College as well as the help from Alpha Epsilon Delta (AED) volunteers.

Description
College-aged women are at an increased risk for the development of subclinical levels of eating disordered symptoms, which have been correlated to lasting deleterious cognitive, physical, and academic effects. The Body Project (TBP) is a universal group-based eating disorder prevention program that targets undergraduate women and challenges thin ideal messages through cognitive dissonance. Burlingame, Strauss, and Joyce (2013) in a meta-analysis of group treatments proposed five factors that independently and congruently work to promote individual change in group treatments: formal change theory, patient characteristics, leader characteristics, structural factors, and small group processes. A host of literature within TBP exists surrounding four of these factors, however, little research has been conducted on the small group processes that moderate individual change within this eating disorder prevention program.
The current study was designed to replicate and extend previous findings on the prevalence of the lemming effect within TBP, as well as examine how the lemming effect is related to outcome of treatment at a 3-month follow-up. Thirty-two participants aged 18-24 were examined. Groups ranged from 3 to 21 participants, including peer leaders. Twenty-nine audio recordings of session one of TBP were coded for lemming effects by the main research, and ten were coded by blind raters for inter-rater reliability measures. Three scales, the Ideal Body Stereotype Scale-Revised (IBSS-R), the Body Parts Satisfaction Scale-Revised (BPSS-R), and the Eating Disorder Examination Questionnaire (EDE-Q), were used to measure levels of thin-ideal internalization, body satisfaction, and frequencies of eating disordered (ED) behaviors, respectively.
Partial correlations revealed nonsignificant relationships between the number of lemming effects and the change in thin-ideal internalization and body satisfaction from baseline to follow-up. Additionally, a reliable change index revealed that the majority of change from baseline to follow-up was reliable for the IBSS-R, and the majority of change for the BPSS-R was unreliable. Lastly, chi-square tests of independence revealed nonsignificant relations between the number of lemming effects and change in ED behaviors.
Due to the small sample and lack of findings, future research would benefit from including a larger sample. This would enable larger power to detect effects and allow for more thorough statistical analyses to be performed to compare the relation of lemming effects to changes in outcome. However, this was the first study to look at the lemming effect variable as a small group process within TBP and added to the growing literature on how small group processes result in efficacious outcomes of treatment within group treatments.

Description
Adults with autism spectrum disorder (ASD) commonly have co-morbid psychiatric symptoms which can decrease quality of life. Although many adults with ASD are achieving greater independence, including attending college, psychiatric symptoms are generally not well controlled in this group. Mindfulness Based Stress Reduction (MBSR) is a program that has successfully been used to reduce the stress, depression, and anxiety symptoms in many clinical and non-clinical groups and may also be effective for college-aged students with ASD. The present investigation assessed the demand, practicality, implementation, adaptation, and acceptability of an MBSR course for college students with ASD. A total of 22 participants completed the questionnaire containing 53 questions and were between the ages of 18 to 64. We found that the MBSR therapy is in high demand for individuals with ASD, and that the participants would be willingly complete the intervention techniques. Participants generally stated that a therapy course like MBSR may help reduce their symptoms, and that they were eager to enroll. Participants were willing to attend all 8 classes during the summer, with a preference for afternoons. Also, modifications including yoga and background music would be accepted by each participant as well as any additional modifications made to the course to meet the needs of the individuals with ASD. Next steps include enrolling and randomizing students into the MBSR course or control group, as well as collect pre- and post-intervention data. We hypothesize MBSR will reduce the psychiatric symptoms and stress levels of individuals in college with ASD, demonstrating its effectiveness in this vulnerable population.

Description
In order to survive, species must regulate their intake of nutrients. In desert leafcutter ant colonies, acquisition of nutrients is not only important for maintaining the health of the colony, but also for the survival of a fungus which the ants cultivate and then consume. This multi-trophic, symbiotic relationship is relatively unique to leafcutter ants and interesting to researchers due to the complexity of how the individual foragers supply nutrients to both the colony and the fungus. The objective of this experiment is to study foraging rates and variation in macronutrient preference among foragers from the same colony of the desert leafcutter ant Acromyrmex versicolor. This study asks if individual foragers vary in their preference of protein to carbohydrate ratios when compared to the overall nutrient content of the colony, and how do these individuals respond as the nutrient content of the available diets increasingly deviates from the previously determined nutritional intake target ratio between 1 Protein:6.3 Carbohydrates to 1 Protein:7.5 Carbohydrates. It was hypothesized that foragers express individualized nutritional preferences that in aggregate balance colony macronutrient consumption, and the number of individuals collecting the diets would decrease as the available nutritional diets deviated away from the colony-level intake target of approximately 1P:7C. The results show trends that support the hypothesis that the number of foraging instances and the number of foragers who exhibit individualized preference towards a certain protein to carbohydrate ratio is highest when the colony is presented with diets that are closest to the colony nutritional intake target.

Description
Each family approaches a cancer diagnosis differently. While some families pursue traditional treatments to the fullest extent, others attempt to refuse chemotherapy, often in favor of alternative medicines. When the patient is a minor, his or her parents have the authority to make medical decisions on their behalf, and this authority is constitutionally protected and socially upheld. However, when the decision to forgo chemotherapy does not comply with minimum standard of care and puts the minor's life in danger, legal action can and has been taken to force the minor to undergo chemotherapy. Legal precedent and biomedical ethics principles guide the decision-making process of the physicians and judges involved, although there is no official framework by which to prioritize these principles. Neglect and abuse procedures, as well as capacity determinations, mature minor doctrines, and religious convictions, add complexity to each forced chemotherapy case. These complexities were explored through the context of four case studies: Cassandra Callendar, who was not granted mature minor status and was forced into treatment by the Connecticut Supreme court; Starchild Abraham Cherrix, who was allowed to pursue the alternative Hoxsey therapy with the consent of his parents and the local court; Dennis Lindberg, a 14-year-old Jehovah's Witness who was permitted to refuse blood transfusions under the Mature Minor Doctrine; and Daniel Hauser, a developmentally delayed teen who was forced to undergo therapy against his parents' religious convictions. In the analysis and comprehensive comparison of these cases, it was concluded that an attempt to establish a protocol by which to determine the ethics of forcing chemotherapy, while well-intended, would ultimately be ineffective and extremely complex. Thus, each forced chemotherapy case must be evaluated on an individual basis.

Description
Chemotherapy refers to the use of chemical agents to inhibit or stop the growth of rapidly dividing cancer cells. There are many side effects of systemic chemotherapy, which are caused because the drug not only kills cancer cells but healthy cells as well (American Cancer Society, 2017). Common side effects include fatigue, hair loss, bruising/ bleeding, infection, anemia, nausea and vomiting, appetite changes, constipation, diarrhea, oral sores, nerve and muscle pain, dry skin and color change, kidney dysfunction, weight loss, cognitive difficulties, mood changes, sexual dysfunction, and fertility problems (American Cancer Society, 2017). Research shows that complementary and alternative medicine (CAM) may help relieve some of the side effects of chemotherapy. Examples of CAM include herbal medicine, dietary supplements, acupuncture, yoga, Tai Chi, massage, electromagnetic therapy, meditation, biofeedback, music, dance, and guided imagery (Johns Hopkins Medicine, 2017). The aim of this creative project was to design a third-party website to provide information to patients undergoing chemotherapy and their family members regarding the use of CAM for the treatment of chemotherapy-induced side effects. Rationale for this project stemmed from a preliminary research step. We analyzed and coded for presence or absence of CAM-specific information on the websites of 20 National Cancer Institute-designated comprehensive cancer centers across the United States. Fifty percent of websites were double-coded. Inter-rater reliabilities (kappa values) for coding of the presence or absence of specific CAM therapies ranged from 0.38 for acupuncture to 1.00 for exercise and yoga, expressive arts, and herbs (mean kappa = 0.75). Fourteen of the 20 websites mentioned meditation or mindfulness; 13 mentioned nutrition; 12 mentioned acupuncture; 11 mentioned exercise or yoga; 11 mentioned massage; 8 mentioned expressive arts; and 3 mentioned herbs. Frequencies for presence of either a description of the specific CAM therapy or an explanation of how the therapy works were lower. We then conducted a literature review using PUBMED to find peer-reviewed research on the efficacy of the previously described seven CAM therapies. The literature search focused on systematic reviews and meta-analyses published within the past 10 years. Based on the literature obtained, we created summaries of the scientific evidence for each CAM therapy. This information is now provided on our third-party website in tabular form with summative statements. The website describes in lay language: chemotherapy, chemotherapy side effects, CAM, seven specific CAM therapies, and evidence for the efficacy or lack thereof of each. Per the American Nurses Association (2015), it is our responsibility to advocate for our patients through education and holistic treatment. The role of the nurse is to educate the patient about treatment options; however, it is not within the nurse's scope of practice to prescribe a treatment. As such, this website should not be viewed as a prescription for CAM therapies, but instead as a user-friendly and easily accessible resource for informed decision-making regarding the adjunctive use of CAM therapies.
