Show moreThe 21st century workforce is very different from the workforce of our predecessors. With the rise in automation and technology there are new demands that are being placed on employers to produce goods that are faster, more personalized, and more accessible. In order to meet these demands, this generation of employees must have a skillset that complements these demands. This skillset includes communication, collaboration, critical thinking, and creativity (4C) skills. The problem of practice addressed in this dissertation is the lack of 4C skills among students currently in the K-12 education system, and the lack of opportunities students have to develop these 4C qualities. This problem was examined through a pilot study that was conducted in the context of a fifth grade setting in a small and rural school district in northeastern Florida. Teachers volunteered to provide a two-week unit of instruction to their students that focused on the development of communication, collaboration, critical thinking, and creativity (4C) skills within the context of state mandated curricular content. Curriculum also promoted the development of students' non-cognitive factors (academic behaviors, academic mindset, learning strategies, social skills, and perseverance) as stepping-stones to refining students' 4C skills. Over the course of the two-week unit, teachers tracked the development of their students' 4C skills, noting their perceived progress of students through teacher focus group sessions and through individual teacher's written reflections. The results revealed that teachers perceived their students 4C skills to improve over the course of the unit of study, especially after the first four days of instruction. One significant finding of the pilot was that teachers who subscribe to a more student-centered philosophy of teaching were more successful with implementing a 4C rich curriculum than teachers who preferred a teacher-centered classroom. Student-centered teachers also perceived more growth in their students' 4C abilities than teachers who were teacher-centered. The framework developed from this study is intended to assist educators who are interested in improving students' 4C abilities. The framework was created and refined to reflect the results of the pilot study. Each of the non-cognitive factors that supported the development of the 4C skills were aligned in a visual and described in a rubric that can be used by educators to guide their students' progression toward proficiency in 4C skills. In this pilot, learning strategies, academic behaviors, and academic mindset were the non-cognitive factors that supported the development of all 4Cs, while social skills were critical to the development of communication and collaboration, and academic perseverance was essential to the development of critical thinking and creativity. The non-cognitive factors that supported the development of each of the 4C skills were aligned in a visual and described in a rubric that can be used by educators who are interested in developing or refining their classroom practice to build these skills among students. Recommendations for further studies include repeating the pilot study with a larger sample size and across multiple grade levels, as well as providing more lengthy and in-depth training for teachers who are interested in promoting 4C skills in their classrooms.

Show moreHuman behavior and decision-making depend largely on past experiences that generate specific action patterns (i.e., scripts, Gioia (&) Manz, 1985) for specific situations. In an ideal world, in which changes in the environment do not conflict with these action patterns, humans would be able to operate consistently, efficiently, and automatically. However, real-world environments are dynamic and fluid, thus altering behavior and forcing changes in scripts. Research suggests that to implement alternate solutions to changing situations, humans select from a (")library(") of learned scripts. Since humans tend to implement scripts to the degree that these are successful over a period of time, implementing alternate scripts can be difficult. That is, unless one has the cognitive flexibility to adapt scripts, implementing a new solution to a problem can be difficult and/or unsuccessful. Cognitive flexibility allows one to restructure knowledge to form an adaptive response to changes set forth by the environment. At issue is the difference between possessing a repertoire of scripts that can be selected and implemented to solve a problem, and having the cognitive flexibility to effectively switch between scripts when a change in context occurs. The purpose of this dissertation is to: (a) evaluate the effectiveness of possessing alternate scripts to respond to situations, and (b) assess the effectiveness of cognitive flexibility training on the ability to switch between scripts. The ultimate goal is to improve mental flexibility in situations where a specific approach should be revised and adjusted to conform to changes in context. A total of 48 participants were randomly assigned to one of four conditions in a 2 (number of scripts) x 2 (training present or absent) design: (a) single script, (b) single script and cognitive flexibility training, (c) two scripts, and (d) two scripts and cognitive flexibility training. Participants either learned one script or two scripts on how to respond to a car engine overheat. In addition, depending on the study condition, participants completed a cognitive flexibility training that used a mental simulation approach. The cognitive flexibility training was intended to allow participants to imagine a number of different scenarios that may impact that task, evaluate assumptions, check assumptions against the situation, imagine a response to such scenarios, and review the effectiveness of the developed solutions. The results of this research suggested that for situations requiring a change or an adaptation to an alternate script, possessing two scripts facilitated correct decision-making, whereas cognitive flexibility training may have hindered decision-making. In addition, for situations requiring a standard script, possessing two scripts was detrimental to decision-making performance, regardless of cognitive flexibility training. Theoretical implications in terms of script-processing and cognitive flexibility, as well as practical implications for training design are provided.

Show moreAcademic dishonesty and academic entitlement plague many college campuses. This research applies the theory of cognitive dissonance to the classroom in an attempt to curb academic dishonesty. Hypocrisy, a branch of the theory of cognitive dissonance, has been induced with regards to health and pro-social causes, but has not been applied to the field of higher education. In order to apply the concept of hypocrisy to academic dishonesty, a two-part experiment was conducted. The first portion of the experiment was an in-class manipulation and the second portion was an online survey conducted one month after the manipulation. Two hundred two students participated in both portions of the experiment. The participants were randomly assigned to one of four conditions (e.g., hypocrisy, commitment only, mindfulness only, control) and participated in two activities. One month after the manipulation took place, students were sent a link to the online survey with a cover story indicating that the survey was part of a research study. After the survey was closed, participants were debriefed and the data was cleaned. Upon analyzing the data, no significant results were detected. The lack of statistical significance was likely due to the month time lapse and the single dose of the manipulation treatment. Overall, this study pioneers the application of hypocrisy in the field of education and provides guidance for future hypocrisy induction studies.

Show moreThe present study explores the nature and structure of spiritual and aesthetic experiences through the interdisciplinary application of neurophenomenology (NP). This approach merges aspects of psychology, neurophysiology, and phenomenology into a unified methodology. The study is nested within a larger project, Space, Science, and Spirituality, and as such, it carries a common goal to use simulation to evoke spiritual and aesthetic responses similar to those expressed by astronauts and cosmonauts. Careful analysis of previous work in NP provided methodological (")lessons learned("), which guided the experimental design, execution, and analysis of the present study. The data collected provides support for experience as a phenomenon that can be studied through empirical means. Further, the articulation of spiritual and aesthetic experiences akin to astronaut experiences corresponds to specific neurological and psychological indicators. Among those indicators are differences in EEG measures during simulation time relative to expressions of spiritual experience following the simulation and changes in visual processing across theta, alpha, and beta signals as correlated with self-identification. These findings support an embodied theory of experience that incorporates memory, executive function, perception, and consciousness. In addition to its academic contribution, this research holds implications for commercial space flight, long-term space missions, post-traumatic stress disorder therapies, and the entertainment industry.

Show moreThis study sought to explore the existence of a relationship between age and/or military affiliation (active, veteran, or family member) and awareness of local community mental health programs available for the treatment of post-traumatic stress disorder. The study separated age from military affiliation to better distinguish between influences on awareness level. Considerations that remain critical regarding post-traumatic stress disorder were described and used to guide a comprehensive review of the literature to find directions to fulfill the goal of this study. A survey was conducted and 586 active military, veterans, and their family members responded to an instrument that contained 40 items. This study was constrained to three items from the survey; age, military affiliation, self-rated awareness of treatment for PTSD. Multiple analysis techniques found no significant (p (<) .05) correlation between either age and awareness or military affiliation and awareness. Further analysis found a significant (p = .003) correlation between veterans and awareness, as well as between family members of veterans (p = .017) and awareness. Veterans and their family members indicated a greater awareness of local community mental health programs available for the treatment of post-traumatic stress disorder than did active troops and/or their family members. The significance of this finding presents new opportunities to study and improve both the marketing and the delivery of mental health treatment for PTSD to the active military population. Multiple opportunities for future research are discussed.

Show moreChanges in physiological function occurring during a body water deficit may result in significant decrements in performance, cognitive function and fine motor control during exercise. This may be due to the magnitude of the body water deficit. Rehydration strategies are important to prevent these deleterious effects in performance. The purpose of this study was to examine the changes before and after prolonged exercise of an alanine-glutamine dipeptide (AG) on cognitive function and reaction time.Twelve male endurance-trained runners (age: 23.5 (&)#177; 3.7 y; height: 175.5 (&)#177; 5.4 cm; weight: 70.7 (&)#177; 7.6 kg) participated in this study. Participants were asked to run on a treadmill at 70% of their predetermined VO2max for 1 h and then run at 90% of VO2max until volitional exhaustion on four separate days (T1-T4). T1 was a dehydration trial and T2-T4 were all different hydration modalities (electrolyte drink, electrolyte drink with a low dose of AG, electrolyte drink with a high dose of AG, respectively) where the participants drank 250 mL every 15 min. Before and after each hour run, cognitive function and reaction tests were administered. Hopkins Magnitude Based Inferences were used to analyze cognitive function and reaction time data.Results showed that physical reaction time was likely faster for the low dose trial than the high dose trial. Dehydration had a possible negative effect on the number of hits in 60-sec compared to both the low and high dose trials. Comparisons between only the electrolyte drink and the high dose ingestion appeared to be possibly negative. Analysis of lower body quickness indicates that performance in both the low and high dose trials were likely improved (decreased) in comparison to the dehydration trial. Multiple object tracking analysis indicated a possible greater performance for dehydration and low dose compared to only the electrolyte drink, while there was a likely greater performance in multiple object tracking for the high dose trial compared to consumption of the electrolyte drink only. The serial subtraction test was possibly greater in the electrolyte drink trial compared to dehydration.Rehydration with the alanine-glutamine dipeptide during an hour run at a submaximal intensity appears to maintain or enhance subsequent visual reaction time in both upper and lower body activities compared to a no hydration trial. The combination of the alanine-glutamine dipeptide may have enhanced fluid and electrolyte absorption from the gut and possibly into skeletal tissue to maintain neuromuscular performance.

Show moreAn integral concern across care settings is the prompt intervention for patients suffering with pain. Long-term care (LTC) settings present with unique challenges to assess and manage pain in resident populations. Pain assessment is especially challenging, because residents have varying degrees of cognition to communicate their pain, and clinician/staff knowledge of pain symptoms may be lacking. The purpose of this research was to improve the measurement of pain and outcomes of care for the elderly residing in skilled nursing care, especially those with cognitive-impairment. The specific aims of this study were to: 1) Determine the magnitude of the relationship between pain behaviors and a measurement model hypothesized for pain; 2) Test the construct validity of a pain measurement model; 3) Examine the concomitance of pain and cognition in a three-year longitudinal analysis. The research questions answered: 1) Is there a difference in the prevalence of pain in cognitively intact versus cognitively-impaired residents; 2) Can a theoretically derived model of pain aid in detecting pain across all cognitive levels; and 3) Do pain and cognitive status concomitantly correlate? The goal was to examine the covariance model of concomitance of pain and cognition to more accurately construct theoretical models of pain to then include additional resident care factors in future research. Traditional self-reports of pain are often under-assessed and under-treated in the cognitively-impaired (CI) elderly resident. Having additional measures to detect pain beyond self-reports of pain intensity and frequency increases the likelihood of detecting pain in populations with complex symptom presentation. Data collected from skilled nursing facilities offer exceptional opportunities to study resident demographics, characteristics, symptoms, medication use, quality indicators, and care outcomes. The Minimum Data Set-Resident Assessment Instrument (MDS-RAI) 2.0, a nationally required resident assessment tool, must be completed on every resident in a Medicare LTC facility within 14 days of admission, quarterly, annually and with significant changes in resident status. Because the MDS is widely used and recognized in LTC settings, core items from MDS [i.e., pain frequency (J2a) and pain intensity (J2b)] along with additional MDS items hypothesized to signify pain were analyzed in the pilot measurement model. Ten core items from MDS were used: 1) Inappropriate behavior frequency (E4da); 2) Repetitive physical movements; 3) Repetitive verbalizations (E1c); 4) Sad facial expressions (E1l); 5) Crying (E1m); 6) Change in mood (E3); 7) Negative statements (E1a); 8) Pain frequency (J2a); 9) Pain intensity (J2b); and 10) Cumulative pain sites scores. All indicators of pain were significant at the p<.01 level. A longitudinal cohort design was used to answer if a concomitance exists between pain and cognition. Data were collected from MDS annual assessments from 2001, 2002 and 2003 for residents across the United States. The sample consisted of 56,494 residents age 65 years and older with an average age of 83 ±8.2 years. Descriptive statistics, ANOVA and a covariance model were used to evaluate cognition and pain at the three time intervals. ANOVA indicated a significant effect (p<.01) for pain and cognition with protected t-tests indicating scores decreased significantly over time with resident measures of pain and cognition. Results from this study suggest that: 1) Using only pain intensity and frequency, pain prevalence was found in 30% of the pilot population, while 47.7% of cognitively intact residents had documented pain and only 18.2% of the severely CI had documented pain, supporting previous research that pain is potentially under-reported in the CI; 2) Parsimonious measurements models of pain should include dimensions beyond self-reports of pain (i.e., cognitive, affective, behavioral and inferred pain indicators); 3) Model fit was improved by using specific MDS items in the pain construct; 4) Longitudinal analysis revealed relative stability for pain and cognition measures over time (e.g., larger stability or consistency was found in cognitive measures than the measures of pain over the three-year period); 5) Crossed-legged effects between pain and cognition were not consistent; 6) A concomitant relationship was not found between pain and cognition. The relationship was significant (p<.01), but associations were weak (r=0.03 to 0. 08). Pain or cognition should not be used as a predictor of the other in theoretical models for similar populations. The MDS is a reliable instrument to follow resident attributes, quality of care, and patient outcomes over time. The development of more accurate assessments of pain may improve resident care outcomes. Ineffectively intervening on the pain cycle is posited to cause secondary unmet needs that affect the resident's quality of life. Findings support the importance of improving clinical outcomes in the management of pain in the elderly residing in long-term care. Deficits in the treatment of pain highlight the impetus to support health policy change that includes pain treatment as a top health priority and a quality indicator for federally funded programs supporting eldercare.

Show moreAlthough Republicans and Democrats frequently disagree ideologically, the leaders of both parties share one commonality in particular - they inevitably make flawed judgments. To adequately understand the extent to which psychological filters act as a fundamental factor in decision making, this thesis shall analyze current political events and observe how partisans within both administrations deal with information incompatible with their own values and beliefs. Specifically referencing the war in Iraq, weapons of mass destruction (WMDs), civil unrest, national security, the national economic climate, and the housing market, this study examines the way leaders deal differently with conflicting information. Although all subjects in the latter shall be discussed, the primary focus is directed towards weapons of mass destruction during the Bush administration and the economic climate during the Obama administration. During their presidencies, both administrations faced different circumstances and congruently possessed different ideologies in respect of how to resolve current problems. Therefore, both President Obama and Bush shall equally be observed in order to adequately compare the extent to which each succumbs to cognitive biases when faced with dissonant information. In addition, groupthink theory, schema theory, and self-justification shall be discussed as complimentary forces which impair political members' decisions. Overall, qualitatively assessing both Republican and Democratic parties in one comprehensive examination breaks the bounds of usual political science studies because both partisans are linked more by their similarities than differences.

Show moreThis study sought to explore if a relationship exists between cognitive load and student satisfaction with learning online. The study separates academic performance (a.k.a., ÂÂ"learningÂÂ") from cognitive load and satisfaction to better distinguish influences on cognition (from cognitive load) and motivation (from satisfaction). Considerations that remain critical to the field of instructional design, as they apply to learning online, were described and used to guide a review of the literature to find directions to fulfill the goal of this study. A survey was conducted and 1,401 students responded to an instrument that contained 24 items. Multiple analysis techniques found a positive, moderate, and significant (p < .01) correlation between cognitive load and satisfaction. Most importantly, the results found that approximately 25% of the variance in student satisfaction with learning online can be explained by cognitive load. New constructs emerged from a Principal Components Analysis that suggest a refined view of student perspectives and potential improvement to guide instructional design. Further, a correlation, even a moderate one, has not previously been found between cognitive load and satisfaction. The significance of this finding presents new opportunities to study and improve online instruction. Multiple opportunities for future research are briefly discussed and guidelines for developing online course designs using interpretations of the emerged factors are made.

Show moreThe objective of this study was to assess low to high levels of Cognitive Workload by measuring heart rate and cortical blood flow in real-time. Four conditions were implemented into a within-subjects experimental design. Two conditions of difficulty and two conditions of trial order were used to illicit different levels of workload which will be analyzed with psychophysiological equipment. Functional Near-Infrared Spectroscopy (fNIRS) has become more prominent for measuring the blood oxygenation levels in the prefrontal cortex of individuals operating in hazardous work environments, students with learning disabilities, and in research for military training. This is due to the fNIR device being highly mobile, inexpensive, and able to produce a high-spatial resolution of the dorsolateral prefrontal cortex during executive functioning. Heart Rate will be measured by an Electrocardiogram, which will be used in concordance with fNIR oxygenation levels to predict if an individual is in a condition that produces low or high mental workload. Successfully utilizing heart rate and blood oxygenation data as predictors of cognitive workload may validate implementing multiple physiological devices together in real-time and may be a more accurate solution for preventing excessive workload.

Specifically, PS has been identified as activator of classical isoforms of protein kinase C, an enzyme known to be involved in the growth and differentiation of neural cells, and is therefore thought to play a role in the protection of neurons.The purpose of this study was to examine the effects of supplementation with PS and caffeine on measures of cognition, reaction time and mood prior to and following an exercise stress. Twenty, healthy, resistance trained males (17) and females (3) (mean (&)#177; SD; age: 22.75 (&)#177; 3.27 yrs; height: 177.03 (&)#177; 8.44cm; weight: 78.98 (&)#177; 11.24kg; body fat%: 14.28 (&)#177; 6.6), volunteered to participate in this randomized, double-blind, placebo-controlled study. Participants were assigned to a PS group (400mg/day PS; 100mg/day caffeine, N=9) or PL (16g/day Carbs, N=11) delivered in the form of 4 candy chews identical in size, shape and color. Subjects performed an acute bout of full body resistance exercise, prior to (T1) and following 14 days of supplementation (T2). Measures of reaction time (Dynavision(&)#174; D2 Visuomotor Training Device), cognition (Serial Subtraction Test, SST), and mood (Profile of Mood States, POMS) were assessed immediately before and following resistance exercise in both T1 and T2. Data was analyzed using two-way ANCOVA and repeated measures ANOVA.Supplementation with 400mg PS and 100mg caffeine did not have a significant impact upon measures of reaction time or cognition between groups at baseline or following acute resistance exercise. However, there was a non-significant trend to the attenuation of fatigue between groups, following acute resistance exercise (p = 0.071). Interestingly, our data suggests that acute resistance exercise alone may improve cognitive function.Although more research is necessary regarding optimal dosage and supplementation duration, the current findings suggest that supplementation 400mg/day PS with 100mg/day caffeine may attenuate fatigue following acute resistance exercise. It is possible that the lack of significance may be the result of both an inhibition of the PS activated pathway and a withdrawal effect from caffeine.

Show moreEmbodied Conversational Agents (ECA) form part of a range of virtual characters whose intended purpose include engaging in natural conversations with human users. While works in literature are ripe with descriptions of attempts at producing viable ECA architectures, few authors have addressed the role of episodic memory models in conversational agents. This form of memory, which provides a sense of autobiographic record-keeping in humans, has only recently been peripherally integrated into dialog management tools for ECAs. In our work, we propose to take a closer look at the shared characteristics of episodic memory models in recent examples from the field. Additionally, we propose several enhancements to these existing models through a unified episodic memory model for ECAÂÂ's. As part of our research into episodic memory models, we present a process for determining the prevalent contexts in the conversations obtained from the aforementioned interactions. The process presented demonstrates the use of statistical and machine learning services, as well as Natural Language Processing techniques to extract relevant snippets from conversations. Finally, mechanisms to store, retrieve, and recall episodes from previous conversations are discussed. A primary contribution of this research is in the context of contemporary memory models for conversational agents and cognitive architectures. To the best of our knowledge, this is the first attempt at providing a comparative summary of existing works. As implementations of ECAs become more complex and encompass more realistic conversation engines, we expect that episodic memory models will continue to evolve and further enhance the naturalness of conversations.

Show moreThe value of this research hinges on the idea that exchanging illustrations for descriptive text can provide appropriate schemas for students with reading difficulties and thereby improve their comprehension and vocabulary acquisition. The research in this dissertation is based on theories and earlier research in the fields of psychology, education, reading, and narratology. A review of these fields offers a variety of perspectives on the processes involved in reading and comprehension. These processes range from the physical systems involved in reading (e.g., early childhood development, eye movement) to the psychological systems, which include cognitive load theory as well as image and text processing models. This study compares two reading methods by analyzing studentsÂÂ' vocabulary and comprehension gains. Both groups read the same text and completed the same pre- and post-tests. The control group read the text from the book which was text only. The experimental group read from a modified text on the computer screen. The text was modified by replacing some sentences with images designed to transmit the same information (e.g., descriptions of the setting, vocabulary items) in a graphic format. The images were in-line with the text, and designed to be read as part of the story, not as additional illustrations. Final analysis shows that the experimental format performed as well as the control format for most students. However, students who have learning disabilities, particularly language learners who have learning disabilities, did not make gains in the text only control format. These same students did show statistically significant gains with the experimental format, particularly the section of reading where the vocabulary words were explicitly presented in the images. Disparate, non-homogenous groupings of students reflect the actual teaching and learning circumstances in the school, as required by the school system. This situation thus represents the actual status quo situation faced by teachers in our school. We leave it to future researchers to work with more homogenous groups of students in order to attain clearer, stronger and more plaintively useful results.

Show morePop culture and social media have become a prime source of entertainment and communication. The current study focuses on the potential effects of consuming this form of media and how it affects our sexual cognitions and behaviors. A sample of nine hundred and two university students were given self-reporting questionnaires concerning demographics, sexual cognitions, and exposure to sexual content in music. An analysis of music artist's posts on social media was also performed. It was hypothesized that artists who have sexual content published in their work will also have the same amount of sexual content on social media. However, there were no significant correlations found between these sources. This study found that exposure to sexual content on social media could increase the chances of acquiring certain sexual cognitions. The current study also aimed to analyze the common characteristics of artist's that post a higher frequency of sexual content on social media. This study found that female artists tend to post more sexual content on social media compared to male artists, as well as music groups containing both male and female artists.

Show moreABSTRACTThe purpose of this study was to examine the means of scores on three forms of a standardized reading comprehension test taken by community college students in developmental reading classes. The three forms of the test were administered as a timed multiple-choice test, a constructed response test, and an un-timed multiple-choice test. Scores on the Group Embedded Figures Test (GEFT) were used to classify the students who participated in the study as having field dependent (LOW GEFT), mid-field dependent/independent (MID GEFT), or field independent (HIGH GEFT) tendencies. The paired samples test was used to analyze the scores among the students classified as LOW GEFT, MID GEFT, and HIGH GEFT for mean differences in scores on the three test formats. The data revealed that for LOW GEFT students, the format of the test impacted their scores, with the mean of the scores of the un-timed multiple-choice test being significantly higher than the timed multiple-choice test and the constructed response format. The data also showed that for the MID GEFT students the mean of the scores for the un-timed multiple-choice test was significantly higher than the means for the timed multiple-choice test scores and the constructed response test scores. However, no significant mean difference was found between the timed multiple-choice test scores and the constructed response test scores. For the HIGH GEFT students, significant mean difference existed only between the un-timed multiple-choice and the timed multiple- choice scores. The means of reading comprehension test scores on the three formats between the LOW GEFT, MID GEFT, and HIGH GEFT students indicated significant mean difference between the timed multiple choice test scores but not between the means of the scores for the constructed response and the un-timed multiple-choice test scores.Demographically, when the means of the reading test scores were analyzed with ethnicity as the controlling variable, the Hispanic students had a significantly higher mean on the scores for the constructed response test format. No other significant mean differences were found between the scores of the African American, Caucasian, Hispanic, or Native American students. When the means of the reading test scores were analyzed with gender as the controlling variable, no significant mean difference was found between the reading comprehension scores of the men and women. This study indicated that cognitive style had more impact on students' performance on a standardized test of reading comprehension than did ethnicity or gender. The un-timed multiple-choice format also had an equalizing effect on the means of the scores for these students.

Show moreThe prevalence of overweight and obese children has increased dramatically in the United States over the past 20 years and is a symptom of multiple systemic and cultural changes that have significantly influenced alterations in energy intake, energy expenditures, and the energy balance of children across the nation. School-based obesity prevention programs addressing nutrition and healthy eating behaviors within the school environment and cultural context provide a unique opportunity to educate and engage students in healthy food consumption practices. This study evaluated the effectiveness of a three-year elementary school nutrition education program for students in grades kindergarten through fifth using a longitudinal analysis of two separate data sets, a nutrition skills behavior assessment survey of self-reported eating behaviors, and body mass index (BMI) scores derived from height and weight measurements of program participants. Nutrition survey results indicated that students reported making healthier food choices from August 2001 to November 2004, with a significant decrease in reported consumption of fats/oils/sweets and significant increases in reported consumption of milk, meat, vegetables, fruit and grains. BMI results indicated a 7.8% decline in the percentage of students in the "overweight" and "at-risk for overweight" categories between August 2001 and October 2004. The combined results of both measures indicate that the nutrition education program appeared to positively affect eating behaviors and body mass index percentages. Implications of the study and strategies for further research are proposed.

Show moreA paradigm shift from static spectrum allocation to dynamic spectrum access (DSA) is becoming a reality due to the recent advances in cognitive radio, wide band spectrum sensing, and network aware real--time spectrum access. It is believed that DSA will allow wireless service providers (WSPs) the opportunity to dynamically access spectrum bands as and when they need it. Moreover, due to the presence of multiple WSPs in a region, it is anticipated that dynamic service pricing would be offered that will allow the end-users to move from long-term service contracts to more flexible short-term service models. In this research, we develop a unified economic framework to analyze the trading system comprising two components: i) spectrum owner--WSPs interactions with regard to dynamic spectrum allocation, and ii) WSP--end-users interactions with regard to dynamic service pricing. For spectrum owner--WSPs interaction, we investigate various auction mechanisms for finding bidding strategies of WSPs and revenue generated by the spectrum owner. We show that sequential bidding provides better result than the concurrent bidding when WSPs are constrained to at most single unit allocation. On the other hand, when the bidders request for multiple units, (i.e., they are not restricted by allocation constraints) synchronous auction mechanism proves to be beneficial than asynchronous auctions. In this regard, we propose a winner determination sealed-bid knapsack auction mechanism that dynamically allocates spectrum to the WSPs based on their bids. As far as dynamic service pricing is concerned, we use game theory to capture the conflict of interest between WSPs and end--users, both of whom try to maximize their respective net utilities. We deviate from the traditional per--service static pricing towards a more dynamic model where the WSPs might change the price of a service almost on a session by session basis. Users, on the other hand, have the freedom to choose their WSP based on the price offered. It is found that in such a greedy and non-cooperative behavioral game model, it is in the best interest of the WSPs to adhere to a price threshold which is a consequence of a price (Nash) equilibrium. We conducted extensive simulation experiments, the results of which show that the proposed auction model entices WSPs to participate in the auction, makes optimal use of the common spectrum pool, and avoids collusion among WSPs. We also demonstrate how pricing can be used as an effective tool for providing incentives to the WSPs to upgrade their network resources and offer better services.

Show moreThis research focuses on technology (specifically video games and interactive software games) and their effects on the cognitive development of children ages 4-8. The research will be conducted as a meta-analysis combining research and theory in order to determine if the educational approach to this age group needs to change/adapt to learners who have been affected by this technology. I will focus upon both the physical and mental aspects of their development and present a comprehensive review of current educational theory and practice. By examining current curriculum goals and cross-referencing them to research conducted in fields other than education (i.e. technology, child development, media literacy, etc.) I hope to demonstrate a need for change; and, at the end of my research, be able to make recommendations for curriculum adaptations that will work within the current educational structure. These recommendations will be made with respect to budget and time constraints.

The participants were simultaneously equipped to the MSB2 and an electrocardiogram (ECG). The results of this study validated the MSB2 for the use in a cognitive task. The study suggests that fitness-tracking devices with similar sampling rates and features are candidates for further exploration as alternatives to ECG, in hope of making the inclusion of physiological data in psychological research more available and accessible.
