Show moreThe purpose of this research study was to explore the impact of virtual character design on user emotional experience and user behavior in a simulated environment. With simulation training increasing in popularity as a tool for teaching social skills, it is essential that social interactions in virtual environments provide authentic opportunities for practice (Swartout et al., 2006). This study used Interactive Performance Theory (Wirth, 2012) to examine the effect of designing a virtual buddy character with ineffective traits instead of effective or expert traits. The sample population for this study (n = 145) consisted of first year university students enrolled in courses in the fall of 2013 at the University of Central Florida. Data on participant emotional experience and behavior were collected through questionnaires, researcher observations, and physiological signal recording that included participant heart rate and galvanic skin response. Data were analyzed using multivariate analysis of variances (MANOVA), Kruskal-Wallis one-way analysis of variance, and qualitative thematic coding of participant verbal behavior and written responses. Results of the analysis revealed that participants who interacted with an ineffective virtual buddy character had statistically significant higher averages of verbal statements to the antagonist in the simulated environment and statistically significant lower perceptions of antagonist amiability than participants who interacted with an effective virtual buddy. Additionally, participants who interacted with a virtual buddy of the opposite gender gave statistically significant higher ecological validity scores to the simulated environment than participants who interacted with a virtual buddy of the same gender. Qualitative analysis also revealed that participants tended to describe the female buddy character with more ineffective traits than the male buddy character even though effective and ineffective design conditions were equally divided for both groups. Further research should be conducted on the effect of virtual buddy character design in different types of simulation environments and with different target audiences.

Show moreOwnership of mobile devices, such as tablets and smartphones, has quickly risen in the last decade. Unsurprisingly, they are now being integrated into the training and classroom setting. Specifically, the U.S. Army has mapped out a plan in the Army Learning Model of 2015 to utilize mobile devices for training purposes. However, before these tools can be used effectively, it is important to identify how the tablets' unique properties can be leveraged. For this dissertation, the touch interface and the interactivity that tablets afford were investigated using a procedural-motor task. The procedural motor task was the disassembly procedures of a M4 carbine. This research was motivated by cognitive psychology theories, including Cognitive Load Theory and Embodied Cognition. In two experiments, novices learned rifle disassembly procedures in a narrated multimedia presentation presented on a tablet and then were tested on what they learned during the multimedia training involving a virtual rifle by performing a rifle disassembly on a physical rifle, reassembling the rifle, and taking a written recall test about the disassembly procedures. Spatial ability was also considered as a subject variable.Experiment 1 examined two research questions. The primary research question was whether including multiple forms of interactivity in a multimedia presentation resulted in higher learning outcomes. The secondary research question in Experiment 1 was whether dynamic multimedia fostered better learning outcomes than equivalent static multimedia. To examine the effects of dynamism and interactivity on learning, four multimedia conditions of varying levels of interactivity and dynamism were used. One condition was a 2D phase diagram depicting the before and after of the step with no animation or interactivity. Another condition utilized a non-interactive animation in which participants passively watched an animated presentation of the disassembly procedures. A third condition was the interactive animation in which participants could control the pace of the presentation by tapping a button. The last condition was a rifle disassembly simulation in which participants interacted with a virtual rifle to learn the disassembly procedures. A comparison of the conditions by spatial ability yielded the following results. Interactivity, overall, improved outcomes on the performance measures. However, high spatials outperformed low spatials in the simulation condition and the 2D phase diagram condition. High spatials seemed to be able to compensate for low interactivity and dynamism in the 2D phase diagram condition while enhancing their performance in the rifle disassembly simulation condition.In Experiment 2, the touchscreen interface was examined by investigating how gestures and input modality affected learning the disassembly procedures. Experiment 2 had two primary research questions. The first was whether gestures facilitate learning a procedural-motor task through embodied learning. The second was whether direct touch input using resulted in higher learning outcomes than indirect mouse input. To examine the research questions, three different variations of the rifle disassembly simulation were used. One was identical to that of Experiment 1. Another incorporated gestures to initiate the animation whereby participants traced a gesture arrow representing the motion of the component to learn the procedures. The third condition utilized the same interface as the initial rifle disassembly simulation but included (")dummy(") gesture arrows that displayed only visual information but did not respond to gesture. This condition was included to see the effects (if any) of the gesture arrows in isolation of the gesture component. Furthermore, direct touch input was compared to indirect mouse input. Once again, spatial ability also was considered. Results from Experiment 2 were inconclusive as no significant effects were found. This may have been due to a ceiling effect of performance. However, spatial ability was a significant predictor of performance across all conditions. Overall, the results of the two experiments support the use of multimedia on a tablet to train a procedural-motor task. In line with vision of ALM 2015, the research support incorporating tablets into U.S. Army training curriculum.

The discharge of nutrients such as nitrogen and phosphorus is particularly damaging as it results in harmful algal blooms which can limit the beneficial use of a water body.

Show moreStormwater runoff from urban areas is a major source of pollution to surface water bodies. The discharge of nutrients such as nitrogen and phosphorus is particularly damaging as it results in harmful algal blooms which can limit the beneficial use of a water body. Stormwater best management practices (BMPs) have been developed over the years to help address this issue. While BMPs have been investigated for years, their use has been somewhat limited due to the fact that much of the data collected is for specific applications, in specific regions, and it is unknown how these systems will perform in other regions and for other applications. Additionally, the research was spread across the literature and performance data was not easily accessible or organized in a convenient way. Recently, local governments and the USEPA have begun to collect this data in BMP manuals to help designers implement this technology. That being said, many times a single BMP is insufficient to meet water quality and flood control needs in urban areas. A treatment train approach is required in these regions. In this dissertation, the development of methodologies to evaluate the performance of two BMPs, namely green roofs and pervious pavements is presented. Additionally, based on an extensive review of the literature, a model was developed to assist in the evaluation of site stormwater plans using a treatment train approach for the removal of nutrients due to the use of BMPs. This model is called the Best Management Practices Treatment for Removal on an Annual basis Involving Nutrients in Stormwater (BMPTRAINS) model.The first part of this research examined a previously developed method for designing green roofs for hydrologic efficiency. The model had not been tested for different designs and assumed that evapotranspiration was readily available for all regions. This work tested this methodology against different designs, both lab scale and full scale. Additionally, the use of the Blaney-Criddle equation was examined as a simple way to determine the ET for regions where data was not readily available. It was shown that the methods developed for determination of green roof efficiency had good agreement with collected data. Additionally, the use of the Blaney-Criddle equation for estimation of ET had good agreement with collected and measured data.The next part of this research examined a method to design pervious pavements. The water storage potential is essential to the successful design of these BMPs. This work examined the total and effective porosities under clean, sediment clogged, and rejuvenated conditions. Additionally, a new type of porosity was defined called operating porosity. This new porosity was defined as the average of the clean effective porosity and the sediment clogged effective porosity. This porosity term was created due to the fact that these systems exist in the exposed environment and subject to sediment loading due to site erosion, vehicle tracking, and spills. Due to this, using the clean effective porosity for design purposes would result in system failure for design type storm events towards the end of its service life. While rejuvenation techniques were found to be somewhat effective, it was also observed that often sediment would travel deep into the pavement system past the effective reach of vacuum sweeping. This was highly dependent on the pore structure of the pavement surface layer. Based on this examination, suggested values for operating porosity were presented which could be used to calculate the storage potential of these systems and subsequent curve number for design purposes.The final part of this work was the development of a site evaluation model using treatment train techniques. The BMPTRAINS model relied on an extensive literature review to gather data on performance of 15 different BMPs, including the two examined as part of this work. This model has 29 different land uses programmed into it and a user defined option, allowing for wide applicability. Additionally, this model allows a watershed to be split into up to four different catchments, each able to have their own distinct pre- and post-development conditions. Based on the pre- and post-development conditions specified by the user, event mean concentrations (EMCs) are assigned. These EMCs can also be overridden by the user. Each catchment can also contain up to three BMPs in series. If BMPs are to be in parallel, they must be in a separate catchment. The catchments can be configured in up to 15 different configurations, including series, parallel, and mixed. Again, this allows for wide applicability of site designs. The evaluation of cost is also available in this model, either in terms of capital cost or net present worth. The model allows for up to 25 different scenarios to be run comparing cost, presenting results in overall capital cost, overall net present worth, or cost per kg of nitrogen and phosphorus. The wide array of BMPs provided and the flexibility provided to the user makes this model a powerful tool for designers and regulators to help protect surface waters.

Methods: Healthy men and women (n=34, age and V ?O2peak= 22.7+3.1yr and 39.3+5.0 mL.kg-1.min-1, respectively) participated in this study. All participants completed a series of tests prior and subsequent to treatment. A maximal oxygen consumption test was performed on a cycle ergometer to assess VO2peak, Tmax, VT, and RCP. The peak power output (Ppeak), power at VT (PVT) and power at RCP (PRCP) were also recorded from this test. Twenty-six subjects completed 12 HIIT (80-120% maximal workload) exercise sessions consisting of 5-6 bouts of a 2:1 minute cycling work to rest ratio protocol over a four-week period, while eight served as controls (CTL). In double-blind fashion, the HIIT groups were assigned into either a placebo (HIIT) or 3g per day of HMB (HMB-HIIT). Body composition was measured with dual energy x-ray absorptiometry (DEXA). Outcomes were assessed by ANCOVA with posttest means adjusted for pretest differences. Results: The HMB-HIIT intervention showed significant (p(<)0.05) gains in VO2peak, VT, and PVT versus the CTL and HIIT group. Both HIIT and HMB-HIIT treatment groups demonstrated significant (p(<)0.05) improvement over CTL for Ppeak, Tmax, RCP, and PRCP with no significant difference between the treatment groups. There were no significant differences observed for any measures of body composition. An independent-samples t-test confirmed that there were no significant differences between the training volumes for the HIIT and HMB-HIIT groups. Conclusion: These findings suggest that the addition of HMB supplementation may result in greater changes in VO2peak and VT than HIIT alone. Therefore, in college-aged men and women, the use of HMB supplementation may enhance the benefits of HIIT on aerobic performance measures.

Show moreAssertiveness is a learned fundamental interpersonal communication skill that helps individuals to meet the social demands of society. Although various personality factors associated with assertiveness have previously been studied, no recently published studies were identified in the review of assertiveness literature. The purpose of this study was to explore the relationship between assertiveness and the five factors of personality (extraversion, neuroticism, openness to experience, agreeableness, and conscientiousness), self-esteem, social anxiety, and shyness to update past research findings. Participants completed the College Self-Expression Scale, the IPIP representation of the NEO PI-R, the Rosenberg Self-Esteem Scale, the Brief Fear of Negative Evaluation Scale, and the Revised Cheek and Buss Shyness Scale. It was hypothesized that assertiveness would correlate positively with extraversion, openness to experience, conscientiousness, agreeableness, and self-esteem. Assertiveness was further hypothesized to correlate negatively with neuroticism, social anxiety, and shyness. Results revealed direct relationships between assertiveness and self-esteem, extraversion, openness to experience, and conscientiousness, as well as inverse relationships to neuroticism, shyness, and fear of disapproval. No significant relationship was found between assertiveness and agreeableness. This study aimed to advance the understanding of the complex personality structure of low-assertive individuals.

Show moreAccording to the ASCA National Model, school counselors are expected to deliver classroom guidance lessons; yet, there has been little emphasis on graduate coursework targeting the development and implementation of guidance curriculum lessons in PSC training. A national study conducted by Perusse, Goodnough and Noel (2001) was conducted looking at how counselor educators were training "entry level school counseling students" in the skills needed for them to be successful as PSCs. They found that of the 189 school counseling programs surveyed only 3% offered a guidance curriculum course and 13.2% offered a foundations in education course. Inferring that many of programs surveyed did not have a course specific to classroom guidance and/or classroom management. A classroom guidance curriculum is a developmental, systematic method by which students receive structured lessons that address academic, career, and personal/social competencies (ASCA, 2005). Classroom guidance lessons provide a forum for school counselors to address such student needs as educational resources, postsecondary opportunities, school transitions, bullying, violence prevention, social-emotional development, and academic competence in a classroom environment (Akos & Levitt, 2002; Akos, Cockman & Strickland, 2007; Gerler & Anderson, 1986). Through classroom guidance, school counselors can interact with many of the students that they would normally not see on a day-to-day basis while providing information, building awareness and having discussions on topics that affect these student populations every day. The present study seeks to explore the use of an innovative method for training PSCs in classroom guidance and classroom management. This method involves the use of a mixed reality simulation that allows PSC students to learn and practice classroom guidance skills in a simulated environment.

Show morePrincipals are considered the educational leaders of their schools and face pressure to improve the quality of education across all levels and disciplines. Principals were interviewed to understand their beliefs, knowledge, and dispositions on staffing teachers in the primary grades. A purposive sample of elementary school principals was drawn from one mid-size suburban district in Florida. Data were analyzed using Bolman and Deal's four-frame organizational theory framework, Cohen's cognitive frame, and Boote's theory of professional discretion.The data strongly suggest that principals do not understand the foundations of early childhood practice. In addition, they do not understand the differences between Early Childhood Education (ECE) and Elementary Education (EE). The principals tend to hire teachers with EE certification as opposed to ECE training. This is partially due to their lack of understanding of ECE and to the perceived advantage of being able to place teachers in a wide range of grade levels. Although all principals stated that primary teaching requires specialized knowledge, most principals consider flexibility to move teachers into the upper grades more important.Three main implications for practice are suggested based on recommendations for advocacy and public education for young children within PreK(-)3rd continuum initiatives. (1) Professional development in ECE should be implemented at the district level for principals to learn and understand the differences in preparation between ECE and EE teacher preparation and to demonstrate the importance of the early years of child development and education. (2) Curriculum enrichment in ECE needs to be added to higher education, graduate teacher leadership programs to demonstrate the importance of the early years of child development and education. (3) The policy for hiring should be centralized at the district level and require teachers with training in ECE for the primary grades. The limitations of the study and recommendations for future research are also discussed.

Show moreThis is an interdisciplinary master's level thesis that explores links among technical writing, training manuals, surveillance, and anti-union rhetoric used with service workers in select American chains and franchises. Brief histories are provided, including those of technical writing, the rise of unions in America, and how technical writing became inextricably linked with labor. A major shift occurred in the 20th century when workers began interacting less with products and more with the public. The research focuses on training manuals, techniques, and rehearsed dialogues of McDonald's, Wal-Mart, Starbucks, Whole Foods, Panera, and Publix, though similar organizations are referenced. Service worker language, uniforms, and store decorum are sometimes analyzed for their rhetorical content. The idea of a single, technically written training manual in the service sector is a misnomer; training is delivered through a pastiche of manuals, videos, computers, apps, flipcharts, and on the job training. Unions are avoided through franchising (and therefore eat outlet not possessing enough workers to organize), creating conditions of high turnover rates, rhetoric, and use of euphemism. Global corporations are likened to "superfiefdoms," with service workers equated to modern serfs. If the world has evolved into supercorporations, it is argued then that the Publix employee-owned model may be the best approach and the most dignified of all. The technical writing and instruction in state-sponsored and federalized school pedagogies, which emphasize drills and compliance, may be culturally linked to the training found in these entry-level service jobs, and more academic study exploring these links is called for.

Show moreDo you remember the first time you used an Automatic Teller Machine (ATM)? Or a pay-at-the-pump gas station? Or an airline e-ticket kiosk? How did you know what to do? Although you never received any formal instruction in how to interact with the self-service technology, you were likely able to accomplish your task (e.g., withdrawing or depositing money) as successfully as an experienced user. However, not so long ago, to accomplish that same task, you needed the direct mediation of a service professional who had been trained how to use the required complex technology. What has changed? In short, the technology is now able to compensate for the average consumer's lack of experience with the transactional system. The technology itself bridges the performance gap, allowing a novice to accomplish the same task as an experienced professional. This shift to a self-service paradigm is completely changing the dynamics of the consumer relationship with the capitalist enterprise, resulting in what is rapidly becoming the default consumer interface of the postmodern era. The recognition that the entire performance support apparatus now revolves around the end user/consumer rather than the employee represents a tectonic shift in the workforce training industry. What emerges is a homogenized consumer culture enabled by self-service technologies--a kiosk culture. No longer is the ability to interact with complex technology confined to a privileged workforce minority who has access to expensive and time-consuming training. The growth of the kiosk culture is being driven equally by business financial pressures, consumer demand for more efficient transactions, and the improved sophistication of compensatory technology that allows a novice to perform a task with the same competence as an expert. "The Kiosk Culture" examines all aspects of self-service technology and its ascendancy. Beyond the milieu of business, the kiosk culture is also infiltrating all corners of society, including medicine, athletics, and the arts, forcing us to re-examine our definitions of knowledge, skills, performance, and even humanity. The current ubiquity of self-service technology has already impacted our society and will continue to do so as we ride the rising tide of the kiosk culture.

Show moreConducting seamless Live Virtual Constructive (LVC) simulation remains the most challenging issue of Modeling and Simulation (M(&)S). There is a lack of interoperability, limited reuse and loose integration between the Live, Virtual and/or Constructive assets across multiple Standard Simulation Architectures (SSAs). There have been various theoretical research endeavors about solving these problems but their solutions resulted in complex and inflexible integration, long user-usage time and high cost for LVC simulation. The goal of this research is to provide an Agile Roadmap for the Live Virtual Constructive-Integrating Training Architecture (LVC-ITA) that will address the above problems and introduce interoperable LVC simulation. Therefore, this research describes how the newest M(&)S technologies can be utilized for LVC simulation interoperability and integration. Then, we will examine the optimal procedure to develop an agile roadmap for the LVC-ITA.In addition, this research illustrated a case study using an Adaptive distributed parallel Simulation environment for Interoperable and reusable Model (AddSIM) that is a component based integrated simulation engine. The agile roadmap of the LVC-ITA that reflects the lessons learned from the case study will contribute to guide M(&)S communities to an efficient path to increase interaction of M(&)S simulation across systems.

Show moreThis study investigated the effects of high intensity interval training (HIIT) and ?-hydroxy-?-methylbutyric free acid (HMBFA) on the onset of neuromuscular fatigue in healthy young men and women. Thirty-seven subjects (22 men and 15 women; mean (&)#177; SD age = 22.8 (&)#177; 3.4yrs) completed an incremental cycle ergometer test (GXT) to exhaustion. During the GXT, electromyography (EMG) signals from the right vastus lateralis were recorded to determine the power output at the onset of neuromuscular fatigue (PWCFT), and peak wattage was used to assign individual training loads.After baseline testing (PRE), subjects were randomly assigned to one of three groups: control (C, n = 9), training with placebo (P, n = 14), or training with supplementation (S, n = 14). Subjects assigned to P and S completed 12 HIIT sessions over 4 weeks while subjects assigned to C were asked to maintain their normal diet and activity patterns. After 4 weeks, subjects returned for post-testing (POST). The PWCFT values (W) were determined using a DMAX method. The EMG amplitude root mean square ((&)#181;Vrms) values were used to generate a third-order polynomial regression (3PR) representing the increase in (&)#181;Vrms versus time of the GXT. The onset of fatigue (TF) was defined as the x-value (time, s) of the point on the 3PR that measured the maximal perpendicular distance from the line between the first and last data points. TF was used to estimate PWCFT according to the equation: PWCFT = PO + a ? (n/N), where PO is the power output of the stage in which TF occurred, a is the increment in power output between GXT stages (25W), n is the difference (s) between TF and the beginning of the stage during which TF occurred, and N is the duration of a stage (120s).A two-way repeated measures ANOVA was used to identify group (&)#215; time interaction for PWCFT. If a significant interaction occurred, one-way factorial ANOVAs were used. Fisher's least significant difference post hoc comparisons were performed between groups. If a significant main effect occurred, dependent samples t-tests with Bonferroni corrections (p = [0.05/3] = 0.017) were performed across time for each group.The two-way ANOVA resulted in a significant interaction (F = 6.69, p = 0.004). Follow-up analysis with one-way ANOVA resulted in no difference among groups at PRE (F = 0.87, p = 0.43), however a significant difference was shown for POST values (F = 5.46, p = 0.009). Post-hoc analysis among POST values showed significant differences between S and both P (p = 0.034) and C (p = 0.003). No differences (p = 0.226) were noted between P and C. Paired samples t-tests detected significant changes following HIIT for S (p (<) 0.001) and P (p = 0.016), but no change in C (p = 0.473).Results of this study indicate that HIIT was effective in delaying the onset of fatigue, but supplementation with HMBFA in conjunction with HIIT was more effective than HIIT alone. An increase in PWCFT represents an increase in the maximal power output an individual can sustain without eliciting fatigue. Therefore, HIIT can be used to improve performance in both endurance activities as well as intermittent sports. In addition, HMBFA supplementation is a simple method that can be used to maximize the benefits of HIIT.Acknowledgments: Metabolic Technologies, Inc. provided the supplement and funding for this study.

Show moreThis research aims to enhance Simulation-Based Training (SBT) applications to support training events in the absence of live instruction. The overarching purpose is to explore available tools for integrating intelligent tutoring communications in game-based learning platforms and to examine theory-based techniques for delivering explicit feedback in such environments. The primary tool influencing the design of this research was the Generalized Intelligent Framework for Tutoring (GIFT), a modular domain-independent architecture that provides the tools and methods to author, deliver, and evaluate intelligent tutoring technologies within any training platform. Influenced by research surrounding Social Cognitive Theory and Cognitive Load Theory, the resulting experiment tested varying approaches for utilizing an Embodied Pedagogical Agent (EPA) to function as a tutor during interaction in a game-based environment. Conditions were authored to assess the tradeoffs between embedding an EPA directly in a game, embedding an EPA in GIFT's browser-based Tutor-User Interface (TUI), or using audio prompts alone with no social grounding.The resulting data supports the application of using an EPA embedded in GIFT's TUI to provide explicit feedback during a game-based learning event. Analyses revealed conditions with an EPA situated in the TUI to be as effective as embedding the agent directly in the game environment. This inference is based on evidence showing reliable differences across conditions on the metrics of performance and self-reported mental demand and feedback usefulness items. This research provides source modality tradeoffs linked to tactics for relaying training relevant explicit information to a user based on real-time performance in a game.

Show moreMindfulness meditation programs, benefits, and outcomes were examined through research previously conducted and published by professionals within five differing disciplines: health and wellness, psychology, elementary education, exceptional education, and medicine. The goal was to find common themes within the differing disciplines in order to gather information about the effectiveness of a mindfulness meditation program to be used in an elementary classroom. In this thesis, the chapter of Health and Wellness is a review of literature that tells the benefits found within meditators, which are not found within non-meditators. The chapter of Psychology explains the social-emotional needs of students, the causes of stress and anxieties amongst students, and the benefits that meditation provides in order to counter the negative effects of stress, anxiety, poverty, etc. The chapter of Elementary Education reviews research literature on the existing mindfulness meditation programs within the United States. This chapter also describes the implementation of such a program in an elementary school, as well as the documented data of the outcomes of the programs. The chapter of Exceptional Education is a review of the research literature on the benefits mindfulness meditation has on students with exceptionalities, such as specific learning disabilities, attention deficit hyperactivity disorder, and autism spectrum disorder. The chapter of Medicine is a retelling of previously published scholarly articles that list the neurological benefits of meditation, and also references the negative side effects to the currently prescribed medications that are being used in the treatment of ADHD.

Show moreRegardless of culture, socio-economic background, and quality of life, all students deserve the highest quality of education. But the reality is, many education systems around the world do not offer it. Investing in structural reforms in education has the potential to boost economic growth in countries around the world. By learning from different education systems strengths and weaknesses, policy decisions can be made that ensure students are given the opportunity for higher educational outcomes. This study analyzes high, middle, and low quality education systems around the world and the infrastructures that lead to educational success or failure. Fifteen education systems are chosen for this study which includes Shanghai-China, Singapore, Japan, Finland, Canada, Portugal, United States, Luxembourg, Spain, Hungary, Brazil, Argentina, Indonesia, Qatar, and Peru. Each system is analyzed in terms of its teacher quality, curriculum, school system structure, and educational equity. From this study, it appears that there is a high-correlation between four indicators and top-educational success. These four indicators include having a highly selective model for hiring teachers, recruiting teachers from a top-pool of graduates, having a high-level of prestige held for teachers in society, and insuring students of low socio-economic status are given equal educational opportunities for success. Recommendations for a new teacher training and selection model are discussed based on the top four indicators. These recommendations could cause educational gains for both the United States and other systems around the world.

Show moreThis study examines how poor labor market opportunities discourage youth between the ages of 15 and 24 and 15 to 29 from participating in the labor market in the European Union between 2005 and 2013. A critical portion of inactive NEETs (youth not in employment, education, or training) reports to be discouraged due to a recognized (")lack of opportunities in the labor market.(") Despite indications from descriptive analyses that the conditions that drive the distinct subsets of the NEET population vary, empirical examinations of the effects of these conditions on the rates of different NEET groups across countries and over time are lacking. The policies prescribed for the NEET group as a whole tend to ignore the special needs of discouraged, inactive NEETs. Beyond the fundamental problem of engaging these individuals in the labor market, neglecting this group has a variety of implications, ranging from social exclusion, to poverty, and even radicalism. A central goal of this project is to determine what a recognized (")lack of opportunities(") means. What is known concretely is that fellow youth are increasingly vulnerable to a range of labor market outcomes and conditions beyond unemployment, including difficulty transitioning into the labor market (school-to-work transitions), in-work poverty risk, non-standard employment opportunities (involuntary and voluntary), limited ability to transition into secure employment (i.e. upward mobility), lower wage levels, atypical employment, limited job security and support, and long-term unemployment. Utilizing aggregated survey data from the EU Labor Force Survey and EU Survey on Income and Living Conditions, I examine how a range of labor market outcomes and conditions for youth, representative of the poor labor market opportunities, affect the frequency of discouraged NEETs across 24 EU countries between 2005 and 2013. Findings suggest that the incidence of involuntary non-standard work, in-work poverty risk, and atypical employment among fellow youth and the incidence of decreased work security among the adult working age population are associated with an increase in discouraged, inactive NEETs. This suggests that engaging this hard to reach subgroup of the NEET population requires a greater emphasis on creating improved labor market opportunities.

Show morePrincipals in the nation's schools have been tasked with managing crisis incidents that may occur with students and others on their campuses on a daily basis. The purposes of this study were to determine the differences, if any, that existed in Central Florida public school principals' perceptions regarding school security, their perceived confidence to address critical crisis incidents on their campuses, their perceptions of the likelihood critical incidents would occur, their perceptions of interaction with law enforcement, the critical incidents they fear the most, and their perceptions of factors impacting the incidents they fear the most. Principal subgroup mean responses to the Principal Safety and Security Perceptions Survey in the three areas of Bandura's (1997) triadic reciprocal causation were examined in the context of principals' gender, longevity, student enrollment, grade configuration, free and reduced lunch rate, presence of a law enforcement officer, and presence of a security plan. Findings revealed significant differences between categorical groups of principals in multiple areas. It was determined that significant differences in principals' perceptions warrant further study. Recommendations for practice include security policy development and practical application of noted trends.

Show moreImprovisation is a construct that uses a set of minimal heuristic guidelines to create a highly flexible scaffold that fosters extemporaneous communication. Scholars from diverse domains: such as psychology, business, negotiation, and education have suggested its use as a method for preparing professionals to manage complexity and think on their feet. A review of the literature revealed that while there is substantial theoretical scholarship on using improvisation in diverse domains, little research has verified these assertions. This dissertation evaluated whether improvisation, a specific type of dramatic technique, was effective for training pre-service teachers in specific characteristics of teacher-child classroom interaction, communication and affective skills development. It measured the strength and direction of any potential changes such training might effect on pre-service teacher's self-efficacy for teaching and for implementing the communication skills common to improvisation and teaching while interacting with student in an inclusive classroom setting. A review of the literature on teacher self-efficacy and improvisation clarified and defined key terms, and illustrated relevant studies. This study utilized a mixed-method research design based on instructional design and development research. Matched pairs t-tests were used to analyze the self-efficacy and training skills survey data and pre-service teacher reflections and interview transcripts were used to triangulate the qualitative data. Results of the t-tests showed a significant difference in participants' self-efficacy for teaching measured before and after the improvisation training. A significant difference in means was also measured in participants' aptitude for improvisation strategies and for self-efficacy for their implementation pre-/post- training. Qualitative results from pre-service teacher class artifacts and interviews showed participants reported beneficial personal outcomes as well as confirmed using skills from the training while interacting with students. Many of the qualitative themes parallel individual question items on the teacher self-efficacy TSES scale as well as the improvisation self-efficacy scale CSAI. The self-reported changes in affective behavior such as increased self-confidence and ability to foster positive interaction with students are illustrative of changes in teacher agency. Self-reports of being able to better understand student perspectives demonstrate a change in participant ability to empathize with students. Participants who worked with both typically developing students as well as with students with disabilities reported utilizing improvisation strategies such as Yes, and..., mirroring emotions and body language, vocal prosody and establishing a narrative relationship to put the students at ease, establish a positive learning environment, encourage student contributions and foster teachable moments. The improvisation strategies showed specific benefit for participants working with nonverbal students or who had commutation difficulties, by providing the pre-service teachers with strategies for using body language, emotional mirroring, vocal prosody and acceptance to foster interaction and communication with the student.Results from this investigation appear to substantiate the benefit of using improvisation training as part of a pre-service teacher methods course for preparing teachers for inclusive elementary classrooms. Replication of the study is encouraged with teachers of differing populations to confirm and extend results.
