These findings suggest the importance of conducting further research on preservice teachers' preparation programs. Preservice teachers' ability to effectively teach the at-risk student can have a lasting impact on these students and their success in the future.

Show moreSupply chain agility has been receiving a lot of attention in recent literature as a way for organizations to become more responsive to change and improve customer service levels. However, agility is typically dealt with qualitatively, and organizations are usually unsure of the steps to take to improve their agility and the customer service level to target. This research studies supply chain agility based on a case study of Intel Corporation, a large semiconductor manufacturer. Here, agility is defined as the ability to satisfy customer demands by reacting effectively to changes in market stimuli. Reacting effectively does not mean reacting to every change in supply or demand. Doing so means increasing supply chain variability unnecessarily, which is amplified by the bullwhip effect. The essence of supply chain agility is determining the degree to which variability should be managed through artificial means such as safety stock, and appropriate triggers for changing production levels and inventory targets. The purpose of this research is to examine factors that influence supply chain agility and identify a cost-effective plan for achieving it. The first phase addresses the problem of identifying target inventory and customer service levels based on regression analysis of historical data and financial analysis of inventory holding costs and stock-out costs. The impact of three factors (forecast error, order lead-time, and demand variability) on the relationship between inventory and customer service level is also examined. The second phase of the research evaluates strategies for production and inventory control with the goal of finding the appropriate trade-off between minimizing cost (of holding inventory and stock-outs) and minimizing variability. Control policies based on the Exponentially Weighted Moving Average (EWMA) control chart with control limits on demand forecasts are proposed to detect when tighter control of processes is necessary. A Monte Carlo supply chain simulation is used to evaluate the performance of these policies under various levels of forecast error and demand variability. Results indicate that several control chart-based policies outperform Intel's current planning policy in terms of cost without significantly increasing variability. The selection of the appropriate policy must be based on the decision-makers' desire to minimize cost compared to the desire to minimize variability, as each policy results in a trade-off between these two objectives.

Show moreWith the emergence of various applications that have different Quality of Service (QoS) requirements, the capability of a network to support QoS becomes more and more important and necessary. This dissertation explores QoS in Cognitive Packet Networks (CPN) by using adaptive routing, flow and congestion control. We present a detailed description and analysis of our proposed routing algorithms based on single and multiple QoS constraints. An online estimation of packet loss rate over a path is introduced. We implement and evaluate the adaptive routing scheme in an experimental CPN test-bed. Our experiments support our claims that the users can achieve their desired best-effort QoS through this routing scheme. We also propose a QoS-based flow and congestion control scheme that is built in the transport layer and specially designed to work with CPN to support users' QoS while remaining friendly to TCP. Theoretical models and experimental analysis are presented. Finally we experimentally demonstrate that the proposed flow and congestion control scheme can effectively control the input flows, react to the congestion and work with our proposed adaptive routing scheme to achieve users' QoS.

A short online survey was conducted to gain insight into their classrooms and perspectives of the subject. The results showed that mathematics anxiety did exist in the classroom, and in-service teachers did report seeing a gender gap between the anxiety experienced by females and males. I believe that from these findings it is important to conduct further research on in-service teachers to see in depth what they think. This is important because their beliefs about the subject can have a lasting impact on their students and their feelings towards mathematics.

Show moreThis study investigates the impact of technological advancement in community bank lending, more specifically, how online financial product and service offerings affect community banks' performance. Community banks, institutions with assets under $1 billion are praised as relationship banking specialists, are important source of credit to individuals and businesses. Their productive performance is highly beneficial for the economic development of the communities and customers that they serve, yet community banks' competitive power against large banks has become increasingly more challenging. Technological advancements radically shift all production and service based industries, including the banking industry and its institutions' offerings. The increasing use of online products and services provides convenience for bank customers, and eventually creates more demand, and boosts up the industry competition. Regarding the impact of technological advancements in the banking industry and the specific position that community banks carries, the question arises of "How does a changing technological landscape affect community banks' performance?". This study aims to contribute to the understanding of how these institutions can better utilize their limited resources to improve their performances.

Show moreThere are more than 2.4 million American public school students identified with learning disabilities who are served under the Individuals with Disabilities Education Act (IDEA). General education preservice teachers are expected to effectively teach all students, including those with disabilities. However, most teacher preparation programs only require a single course in teaching students with disabilities. Research shows that that teachers� attitudes regarding inclusion are the greatest predictor of a successful inclusion classroom. This study explored the attitudes of preservice elementary and preservice secondary teachers regarding integrating students with disabilities into general education classrooms. A quantitative research design with a survey method was used in this study. The survey method included a questionnaire via Qualtrics, an online survey system used at the University of Central Florida. Findings of this study revealed that 40% of preservice teachers indicated that integrating students with disabilities in the general education class was a burden. However, due to information limitations the results for preservice elementary and preservice secondary teachers� attitudes regarding the integration of students with disabilities in the general education classroom and the number of hours of service learning completed was inconclusive.

This study involved the use of questionnaires with 100 teacher candidates enrolled on an introductory course on diversity in education in a Florida university. Teacher candidates responded to a series of items to identify beliefs about giftedness within and outside the context of education as well as the value of training in gifted education for educators. Of the 100 respondents, 79% agreed or strongly agreed with the need for specialized training for educators working with gifted students. 60.6% of respondents agreed or strongly agreed with outcomes with gifted students being positively influenced by research of and experiences with gifted students. The data showed a statistically significant, positive correlation between attitudes towards giftedness within education and agreement with outcomes with gifted students being positively influenced by research of and experiences with gifted students. Results suggest teacher candidates recognize a value in training in gifted education but do not see themselves as gifted educators and are unaware of how to be trained in gifted education.

Show moreWireless ad hoc network consists of inexpensive nodes that form a mobile communication network. Due to limitations of the transmission range, the nodes rely on each other to forward packets such that messages can be delivered across the network. The selection of the path along which a packet is forwarded from the source node to the destination node is done by the routing algorithm. Most commonly used routing algorithms, though effective for non-real time applications, cannot handle real-time applications that require strict delay bounds on packet delivery. In this thesis, we propose a routing protocol that ensures timely delivery of real time data packets. The idea is to route packets in such a way that irrespective of factors like traffic load and node density, the average delay remains within acceptable bounds. This is done by carefully accessing the resources available to a route before a session is admitted along that route. Each link in the route is checked for sufficient bandwidth not only for the new session to be admitted but also for the sessions that are already using that link. The new session is admitted only if the admission does not violate the delay bounds of any on-going sessions. This method of route selection coupled with per-hop link reservations allows us to provide bounds on the delay performance. Extensive simulation experiments have been conducted that demonstrate the performance of the proposed routing protocol in terms of throughput, session blocking probability, packet drop probability, average path length, and delay.

Show moreInequities in access to health services has negative consequences on individual well-being, and imposes financial and emotional burden on patients, families, health care systems, and the public. Inequities engendered from differences in socioeconomic status, health insurance coverage, race, and other characteristics can engender disparities. This study aimed to identify the potential predictors of unmet medical need among the civilian noninstitutionalized U.S. adults. Inability to receive needed medical care or receiving medical care after a delay, due to the associated costs, constructed unmet medical need. This study used a four-year (2014-2017) National Health Interview Survey (NHIS) data (sample size: 296,301 adults) and implemented a conceptual framework to study disparities in access to health services and estimate the relative importance of predisposing, enabling, and need factors as the predictors of unmet medical need. Findings from machine learning and logistics regression models highlight the importance of health insurance coverage as a key contributing factor of health disparities. About 60% of variation in unmet medical need was predictable, with over 90% accuracy, solely with health insurance coverage status. Self-rated health status, family structure, and family income to poverty ratio were other statistically significant predictors. Even after controlling for a wide variety of sociodemographic and health status variables such as age, gender, perceived health status, education, income, etc., health insurance remains significantly associated with unmet medical need (OR: 5.03, 95%CI: 4.67-5.42). To ensure precise national estimates, proper survey data analysis methods were incorporated to account for the complex sampling method used by NHIS. Furthermore, the enabling factors (health insurance and income) exert much more weight on unmet medical need than predisposing factors and need factors. The findings raise the concerns about the existence and magnitude of disparities in health care access and provide a comprehensive framework to a target population for understanding the sources of health inequities with data-driven evidence. Results can be utilized to address potential areas for designing public policy and program interventions by identifying the relative vulnerability of different population groups for lacking access to affordable health services. Future studies using longitudinal panel data are necessary to establish a causal relationship between the predictors and unmet medical need.

Show moreState-of-the-art domestic robot assistants are essentially autonomous mobile manipulators capable of exerting human-scale precision grasps. To maximize utility and economy, non-technical end-users would need to be nearly as efficient as trained roboticists in control and collaboration of manipulation task behaviors. However, it remains a significant challenge given that many WIMP-style tools require superficial proficiency in robotics, 3D graphics, and computer science for rapid task modeling and recovery. But research on robot-centric collaboration has garnered momentum in recent years; robots are now planning in partially observable environments that maintain geometries and semantic maps, presenting opportunities for non-experts to cooperatively control task behavior with autonomous-planning agents exploiting the knowledge. However, as autonomous systems are not immune to errors under perceptual difficulty, a human-in-the-loop is needed to bias autonomous-planning towards recovery conditions that resume the task and avoid similar errors.In this work, we explore interactive techniques allowing non-technical users to model task behaviors and perceive cooperatively with a service robot under robot-centric collaboration. We evaluate stylus and touch modalities that users can intuitively and effectively convey natural abstractions of high-level tasks, semantic revisions, and geometries about the world. Experiments are conducted with `pick-and-place' tasks in an ideal `Blocks World' environment using a Kinova JACO six degree-of-freedom manipulator. Possibilities for the architecture and interface are demonstrated with the following features; (1) Semantic `Object' and `Location' grounding that describe function and ambiguous geometries (2) Task specification with an unordered list of goal predicates, and (3) Guiding task recovery with implied scene geometries and trajectory via symmetry cues and configuration space abstraction. Empirical results from four user studies show our interface was much preferred than the control condition, demonstrating high learnability and ease-of-use that enable our non-technical participants to model complex tasks, provide effective recovery assistance, and teleoperative control.

Yet, it has become increasingly clear teacher stress may start prior to entering the profession (Brown (&) Ryan, 2003, Darling-Hammond, 2006). The researcher used a non-experimental design to evaluate the perceived stress among pre-service teachers enrolled in internship, and if the coping style of mindfulness had any correlation on self-reported stress levels. The quantitative study surveyed 332 student interns using the Perceived Stress Survey (Cohen (&) Williams, 1988) to depict perceived stress levels of pre-service teachers. A demographic questionnaire was also administered. The results indicated an increase in perceived stress, suggesting that stress may vary across the demographic variables of gender. Mindfulness was researched as a potential solution, however, there was no correlation between mindfulness and stress levels. education is necessary in the discussion and implementation of mindfulness as a potential intervention tool for stress. Further research is needed for a deeper understanding of gender, and how mindfulness may be a positive intervention to perceived stress.

Show moreMotel life has existed in the United States for over 100 years. However, it was not until the HEARTH Act in 2009 changed the federal definition of homelessness that those who live in motels more or less permanently were considered homeless persons. This project utilizes qualitative, semi-structured interviews with 18 families with children who are living in motels to explore their experiences with motel life and social service providers, their housing identity, and identity management strategies. Interviews with social service providers were also conducted for context and to gain their perspective on families living in motels. Findings show that most of the motel residents did not identify with the conventional definition or image of homelessness and instead negotiated the term to fit their situation. Although they did not initially self-identify as homeless, when discussing policy recommendations all participants adopted a homeless social-identity (i.e., they identified as members of the homeless social category). As members of the homeless community, the participants agreed that homeless families in the area needed more attention and assistance. The identity management strategies employed by the participants were meant to show how they were good people who were just stuck in a motel because of circumstances outside of their control and how they were deserving of assistance to help their families move out of the motel and obtain adequate, permanent housing. Interviews with the social service providers showed that they often do exercise their power over clients by classifying them into a "deserving" group or a "not willing to work for it" group based on their own experiences and prejudices.

Show moreMany historians have conducted oral history interviews with Vietnam War veterans in an attempt to offer a more personal perspective to the study of the Vietnam War; however, most historians do not consciously differentiate between drafted and volunteer veterans. Identifying whether a veteran was drafted into service or volunteered is critical because the extent to which this service was voluntary or coerced may affect the way a veteran remembers his military service. By conducting oral histories, one can consciously delineate service members who volunteered as opposed to those who were drafted to determine if the veterans' experiences change based on the nature of their entry into the military. Additionally, examining the implementation of a national draft and its effects on service members' experiences will offer a better understanding of American military history. While much of the attention of scholars has been on drafted soldiers in Vietnam, little research has been conducted on the experience of the volunteer soldier.This study relies on oral history interviews conducted with volunteer and drafted service members of the Vietnam War to determine if there were differences between draftees and volunteers based on their entrance into the military. The research and oral history interviews with the two veteran groups establishes that the dissent detailed by draft protesters was not always the case and service members, volunteers and draftees alike, more often than not accepted their military service. The interviewed veterans' responses suggest that resistance to military service during the Vietnam War may not have been as great as one might think given the attention that has been placed on the anti-draft movement.

Show moreThe researcher utilized the 2007 American College Personnel Association (ACPA) Steering Committee on Professional Competencies report, Professional Competencies, to determine the importance of a set of competencies for work in entry-level student affairs positions. The researcher also studied whether there were any differences in importance of these competencies based on functional area (e.g., residence life/housing, student activities) and institutional type (i.e., four-year public and four-year private). Via an online questionnaire, the researcher sent the list of competencies to a sample of 970 members of ACPA who were self-selected as entry-level members and received 224 usable responses. Of the 75 individual competency items studied, 66 were found to be, minimally, Ã‚Â"importantÃ‚Â" for entry-level positions overall, thus reinforcing the fact that entry-level practitioners need a wide array of competencies to perform the responsibilities within their positions. Competencies related to advising and helping others, including students and colleagues, were rated the highest, while those related to the legal foundations of the field were rated the lowest, yet still at least Ã‚Â"somewhat important.Ã‚Â" Several significant differences were found between groups within the studied demographic variables and the degree of importance of the competencies. Specifically, there were very few significant differences in the degree of importance of competencies based on respondent institutional type. Compared to other demographic items, functional area by far indicated the most significant differences between groups.

Show moreABSTRACT Six Sigma is a business improvement strategy that aims to improve process performance using a structured methodology that identifies and removes the causes of defects in manufacturing and business processes, while implementing the lean concepts attempts to remove wasteful activities from those processes. In practice, the Six Sigma strategy and the Lean philosophy are combined and often viewed as one integrated philosophy, where the philosophy of Lean Six Sigma simultaneously removes wasteful activities from a process and reduces the variability of that process. This thesis research reviews the concepts and implementation of Lean thinking, Six Sigma strategy, and the integrated concept of Lean Six Sigma, with emphasis in service organizations. Most importantly, this thesis summarizes the critical success factors for implementing Lean Six Sigma within a service business environment and categorizes them within a proposed multi-level taxonomy that can be used by service business units and service providers to improve the success of Lean Six Sigma implementation.

Show moreThis dissertation investigates the role of two marketing practices---returns policies and group-buying services---in improving channel coordination. The first study (presented in Chapter Two) focuses on the interaction between two types of returns policies---returns of unwanted products from consumers to retailers and returns of unsold inventory from retailers to manufacturers. Even without the right to return unsold inventory to the manufacturer, the retailers may accept returns from consumers; by doing so, they benefit from a less price-sensitive market demand, an ability to screen for high-valuation consumers, and a competitive advantage (offering a returns policy makes a retailer more attractive to consumers). From the manufacturer's perspective, accepting returns may induce the retailers to order more stock, set lower prices, generate more sales, and therefore, improves the performance of the channel. However, under some conditions (e.g., when the marginal cost of stock-outs is relatively high), this study shows that this effect disappears and the manufacturer does not accept returns from the retailer in equilibrium. The second study (presented in Chapter Three) investigates the rationale for using group-buying services vis-a-vis the traditional posted-pricing mechanism. It focuses on the behavior of consumers and explores the role of heterogeneity in their valuation for the product and cost of purchasing via group-buying in the functioning of group-buying services as a price-discrimination device. Finally, the role of group-buying services in improving channel coordination under asymmetric information is studied in Chapter Four. This analysis shows that the availability of group-buying services provides an opportunity for the manufacturer to reduce the informational rents of the retailer arising from its private information about the market condition. Interestingly, the manufacturer can avoid paying these rents and regains the first-best profitability when asymmetry in information exists regarding the relative sizes of consumer segments. In other settings (e.g., when asymmetric information exists regarding consumers' price sensitivity), leveraging the group-buying mechanism nevertheless allows the manufacturer to design a contract that requires lower rents and improves channel coordination to some extent.

Title: A GOVERNANCE REFERENCE MODEL FOR SERVICE-ORIENTED ARCHITECTURE-BASED COMMON DATA INITIALIZATION: A CASE STUDY OF MILITARY SIMULATION FEDERATION SYSTEMS.
Creator: Lanman, Jeremy, Proctor, Michael, University of Central Florida
Abstract / Description: Military simulation and command and control federations have become large, complex distributed systems that integrate with a variety of legacy and current simulations, and real command and control systems locally as well as globally. As these systems continue to become increasingly more complex so does the data that initializes them. This increased complexity has introduced a major problem in data initialization coordination which has been handled by many organizations in various ways....
Show moreMilitary simulation and command and control federations have become large, complex distributed systems that integrate with a variety of legacy and current simulations, and real command and control systems locally as well as globally. As these systems continue to become increasingly more complex so does the data that initializes them. This increased complexity has introduced a major problem in data initialization coordination which has been handled by many organizations in various ways. Service-oriented architecture (SOA) solutions have been introduced to promote easier data interoperability through the use of standards-based reusable services and common infrastructure. However, current SOA-based solutions do not incorporate formal governance techniques to drive the architecture in providing reliable, consistent, and timely information exchange. This dissertation identifies the need to establish governance for common data initialization service development oversight, presents current research and applicable solutions that address some aspects of SOA-based federation data service governance, and proposes a governance reference model for development of SOA-based common data initialization services in military simulation and command and control federations.

Show moreThe accomplishment of pilot implementation of the HIVQUAL-T model, an innovative HIV care quality management tool, has led to an authoritative decision to scale up the use of the model nationwide in Thailand. However, the level of implementing this model varies across target hospitals. Some hospitals have fully adopted the model by conducting quality improvement (QI) activities following performance measurement (PM) results while others have partially adopted only PM or have not used this model at all. The differential level of implementation could be a contributing factor accounting for discrepancies in the quality of care across different HIV ambulatory care facilities. A cross-sectional study was conducted by using two main datasets, including Thailand's national HIV care performance results and an online survey of all public hospitals nationwide. A total of 382 hospitals responded to the survey, accounting for a response rate of 50%. A confirmatory factor analysis (CFA) method was performed to examine the validity of latent constructs developed from the diffusion of innovation theory. Structural equation modeling (SEM) approach was employed to investigate the relationship between the determinants of organizational decision-making and their contribution to organizational outcomes, under the context-design-performance framework. Furthermore, using a panel model of hospitals that reported performance results across a 3-year period, the improvement in HIV ambulatory services performance among the adopters was examined. The results indicated that two innovation attributes -relative advantage and simplicity perceived by HIV care practitioners in hospitals- were found to be positively associated with the level of the HIVQUAL-T model implementation. Two structural characteristics -interconnectedness and organizational slack- appeared to be positively associated with the level of model implementation, while rate of adoption in the region also had significant positive contribution. Ultimately, the extensiveness of the HIVQUAL-T model implementation demonstrated a proportionate impact on the variation in hospitals' HIV ambulatory services performance. It was noted that the implementers considerably improved their performance within two years of implementing the model. The study findings imply that adoption is more likely when individual practitioners assess the innovation and find it to be easy to comprehend and operate and also worthwhile to implement. Furthermore, hospitals' decision making is likely influenced by their relations to external environment. The findings suggest more emphasis on individual and hospital-level capacity building for meaningful use of this quality management initiative, accompanied by an adjustment of performance measurement software with valid, reliable, and interpretable indicators.

Title: Les Temps Roulent: An Analysis of Emergency Medical and Police Response Times to Shootings and Lethality in New Orleans.
Creator: Sacra, Sarah, Corzine, Harold, Huff-Corzine, Lin, Gay, David, McCutcheon, James, University of Central Florida
Abstract / Description: Lethality of aggravated assaults has long been discussed in terms of weapons used, location of assault, demographics of victims, and regions of the US in which the assault occurred. However, dating back to the 1950s, medical response times have been discussed as a mediating factor, but minimally explored in analyses. The current study assesses the lethality of shootings with a primary focus on emergency medical and police response times in New Orleans, LA. Along with routine activities and...
Show moreLethality of aggravated assaults has long been discussed in terms of weapons used, location of assault, demographics of victims, and regions of the US in which the assault occurred. However, dating back to the 1950s, medical response times have been discussed as a mediating factor, but minimally explored in analyses. The current study assesses the lethality of shootings with a primary focus on emergency medical and police response times in New Orleans, LA. Along with routine activities and social disorganization indicators, 102 shootings that occurred in 3 months are analyzed to establish response time patterns of lethality. Results indicate that neither medical nor police response times impact the odds of a victim surviving a shooting, but instead, it is the days on which the violent encounters occur and the socioeconomic characteristics of the neighborhood that have a stronger influence on life or death, although not statistically significant. Limitations and future research directions are discussed.

Title: Pervasive Secure Content Delivery Networks Implementation.
Creator: Lugo-Cordero, Hector, Guha, Ratan, Stanley, Kenneth, Chatterjee, Mainak, Wu, Annie, Lu, Kejie, University of Central Florida
Abstract / Description: Over the years, communication networks have been shifting their focus from providing connectivity in a client/server model to providing a service or content. This shift has led to topic areas like Service-Oriented Architecture (SOA), Heterogeneous Wireless Mesh Networks, and Ubiquitous Computing. Furthermore, probably the broadest of these areas which embarks all is the Internet of Things (IoT).

Show moreOver the years, communication networks have been shifting their focus from providing connectivity in a client/server model to providing a service or content. This shift has led to topic areas like Service-Oriented Architecture (SOA), Heterogeneous Wireless Mesh Networks, and Ubiquitous Computing. Furthermore, probably the broadest of these areas which embarks all is the Internet of Things (IoT). The IoT is defined as an Internet where all physical entities (e.g., vehicles, appliances, smart phones, smart homes, computers, etc.), which we interact daily are connected and exchanging data among themselves and users. The IoT has become a global goal for companies, researchers, and users alike due to its different implementation and functional benefits: performance efficiency, coverage, economic and health. Due to the variety of devices which connect to it, it is expected that the IoT is composed of multiple technologies interacting together, to deliver a service. This technologies interactions renders an important challenge that must be overcome: how to communicate these technologies effectively and securely? The answer to this question is vital for a successful deployment of IoT and achievement of all the potential benefits that the IoT promises.This thesis proposes a SOA approach at the Network Layer to be able to integrate all technologies involved, in a transparent manner. The proposed set of solutions is composed of primarily the secure implementation of a unifying routing algorithm and a layered messaging model to standardizecommunication of all devices. Security is targeted to address the three main security concerns (i.e., confidentiality, integrity, and availability), with pervasive schemes that can be employed for any kind of device on the client, backbone, and server side. The implementation of such schemes is achieved by standard current security mechanisms (e.g., encryption), in combination with novel context and intelligent checks that detect compromised devices. Moreover, a decentralized content processing design is presented. In such design, content processing is handled at the client side, allowing server machines to serve more content, while being more reliable and capable of processing complete security checks on data and client integrity.
