- Abstract/Description

Prospective memory is remembering to perform an action in the future, such as attending a meeting (a time-based task) or picking up milk at the gas station (an eventbased task), and is crucial to achieving goal-directed activities in everyday life. Children who fail to develop prospective memory abilities are likely to experience difficulties interacting with parents, teachers, and peers.

Show moreProspective memory is remembering to perform an action in the future, such as attending a meeting (a time-based task) or picking up milk at the gas station (an eventbased task), and is crucial to achieving goal-directed activities in everyday life. Children who fail to develop prospective memory abilities are likely to experience difficulties interacting with parents, teachers, and peers. To date, research on prospective memory development has been primarily descriptive or focused on underlying executive functioning. This dissertation investigated the developmental relationship between metacognitive representation and prospective memory in preschool and elementary school children and adults. Findings from Study 1 indicated that individual differences in representational ability independently predicted individual differences in 3-year-olds' performance on event-based tasks that are of low-interest. Qualitative changes are important to consider when modeling prospective memory develop ment, as with episodic memory. Study 2 presents findings based on a study using the CyberCruiser 2.0, an Xbox-style racing game designed to assess time-based prospective memory. This study confirmed that kindergarten children are capable of completing this time-based prospective memory task but revealed that performance improved with age. Between kindergarten and 2nd grade, children become better aware of their own mental processes and abilities, allowing them to adjust their strategies and perform more comparable to adults. As a result, in this study, younger children tended to overestimate their prospective memory abilities and were less likely to monitor passing time, causing them to fail more time-based task trials than older children and adults., Similarly, participants who underestimated the costs of prospective memory failed more time-based tasks relative to those who more accurately assessed these costs. Although this latter relationship was limited to adults, it suggests that a poor metacognitive understanding of the costs of prospective memory may result in missed opportunities to carry out a delayed intention if individuals fail to allocate attentional resources appropriately. These findings have theoretical implications for models of prospective memory and development. Practical implications for educating children are also discussed.

Show moreThis study examines the effects of epistemic motives and individual social structure (strength of social ties) on individual actions. lt has been suggested that the informal structure of relations that develops within firms affects the actions of individuals perhaps more so than formal structure. Ifthis is true, when studying organizations perhaps more effort should be given to examining the effects of the structure of social relations within the firm . This study has attempted to take the first steps in beginning to systematically study identifiable and predictable effects of the informal structure of relations on the behavior of individuals. During the process of examining the etfects of epistemic motives and individual social structure on the actions of individuals, two important questions were addressed. First, what are the effects of epistemic motives on the formation of individual social structure? The findings of this study suggest that the need for closure and the need for cognition affect the formation of individual social structure in different and identifiable ways. In addition, the level of epistemic motivation atiects the degree to which social interactions affect tie strength. The second question is what are the effects of individual social structures on individual actions? The findings of this study suggest that the tie strength of an individual's social structure appears to affect interdependent actions; but, tie strength does not affect independent actions. In addition, an understanding about individuals' inclinations to take interdependent or independent actions is enhanced when the effects of both epistemic motives and social structure are considered. The findings of this study suggest that information about the epistemic motives of employees can provide insight into the fonnation of the individual social structures and the intrinsic desire of employees to take interdependent or independent actions. The effects of epistemic motives and individual social structure on individual actions, the organizing process and the formulation and implementation of strategies are discussed.

Show moreThis thesis deals with remote database access over the Internet. Three different approaches to remote database access, the CGI-based approach, the Oracle Webserver-based approach and the CORBA-based approach, are discussed. Experiments are conducted to compare the pros and cons of each approach. The Oracle database and Microsoft Access database are utilized as the target database systems. For the CGI-based approach, the CGI programs are coded with ProC, Oracle's SQL-embedded C language, in Microsoft Visual C++ developer's studio, and a Student Record example is demonstrated. For the Oracle Webserver-based approach, the Oracle Webserver 1.1 has been setup and an Online Shopping Club example is demonstrated. For the CORBA-based approach, Orbix Web 2.0.1 and JDK 1.1.1 are utilized as the CORBA system and the development language, respectively, and several examples including single server, multiple servers and multiple databases are presented. An extended SQL syntax is proposed to manipulate data from multiple database systems residing on different hosts in one SQL statement. The implementation of extended SQL statements in CORBA's server/client application is also suggested. With the help of extended SQL syntax and CORBA's multiple server access feature, an example of the client application accessing two databases at a time is illustrated. The pros and cons are discussed of the three remote database access approaches studied in the thesis: (I) The CGI-based approach, which is the most generic and widely used approach. (II) The Oracle Webserver approach, which is a relatively simplified way of the CGI approach, easy to apply but limited in applications. (III) The CORBA-based approach, which is the most powerful and sophisticated approach for remote database access.

Show moreGames have become important applications on mobile devices. A mobile gaming approach known as remote gaming is being developed to support games on low cost mobile devices. In the remote gaming approach, the responsibility of rendering a game and advancing the game play is put on remote servers instead of the resource constrained mobile devices. The games rendered on the servers are encoded as video and streamed to mobile devices. Mobile devices gather user input and stream the commands back to the servers to advance game play. With this solution, mobile devices with video playback and network connectivity can become game consoles. In this thesis, we present the design and development of such a system and evaluate the performance and design considerations to maximize the end user gaming experience. A gaming user experience model capable of predicting the user experience for a given gaming session is developed and verified.

Show moreAlthough there are effective medications to lower blood lipid levels, studies show that comprehensive nutritional counseling provides more effective and lasting results on blood lipids in comparison to standard of care with solely pharmacological intervention (Sialvera et al., 2017). Changes in diet such as reducing saturated fat and increasing fiber intake, are two of many alterations that have been proven to be successful and have consequently helped reduce the relative risk of ASCVD (Masana et al., 2017). The purpose of this quality improvement project was to direct participants with hyperlipidemia in the management of the condition using evidence-based nutrition guidelines and recommendations. The approach targeted underserved adults newly diagnosed with hyperlipidemia and seeking care at Broward Community and Family Health Center located in southeastern Florida. The community member, Mr. Laine, communicated that greater information on the dietary management of hyperlipidemia is beneficial to those who are determined to make changes to improve diet and lower blood cholesterol levels (S. Laine, oral communication, January 2019). Based on previous clinic data, there was a need for greater emphasis on nutritional education to assist clients in the control of hyperlipidemia.

Show moreIn the past few years many US institutions of higher education have established virtual classrooms where learners pursue higher education via the Internet. The true challenge in Distance Education however remains; how do students perform real lab experiments--such as electronics over the Internet? To examine this challenge, a survey was conducted on over fifty Web-based educational environments, to assess the shortcomings of laboratory facilities currently available on the Internet. The survey revealed that contemporary labs touted to be virtual environments are merely software simulations. Hence the new idea of a facility that will realistically provide lab experiments over the Internet. With this aim, an innovative system is designed using object-oriented methodologies in Unified Modeling Language to include all aspects of software and hardware. Java/RMI is used as the system's development tool. An experiment to measure the "VI characteristics of a Resistor" is built using National Instruments' DAQ systems. The students can logon through the Internet, register, and perform experiments by sending various current values, and measure the corresponding voltages across a resistor. The results are submitted for grade and the teaching assistant can grade the student after observing the input and output values over the Internet.

Show moreThis Thesis explores building low cost and reliable portable laboratory infrastructure platform for Logic Design, methods for allowing access to modern test equipment via the internet, and issues related to academic integrity. A comprehensive engineering education, per ABET, requires an equal emphasis on both lecture and laboratory components. The laboratory experience builds and establishes a foundation of skills and experiences that the student cannot obtain through any other means. The laboratory must use modern, pertinent methods and techniques including the use of appropriate tools. This is especially true when it comes to test equipment. Engineering students require and deserve training on and access to modern test equipment in order to obtain better career opportunities. However, providing access to modern and relevant labs requires a significant budget commitment. One way to extend current budgets is to adopt the growing concept of “remote labs.” This approach allows higher utilization of existing (and costly) equipment, it improves an institution’s Return on Investment (ROI), and also can be used to meet the needs of students’ complicated schedules, especially in the case of a “commuter campus,” where a majority of students live off campus. By developing remote labs, both the institution and the students benefit: Institutions increase equipment utilization, and utilize space, budgets and support personnel more efficiently. Students can access a lab whenever and wherever they have internet access. Finally, academic integrity must be protected to ensure the potential of remote laboratories in education. This Thesis presents a design and implementation plan for a low cost Logic Design laboratory infrastructure built and tested over 3 years by over 1,500 Logic Design students; a design and implementation of the infrastructure to include the ability to measure using remote test equipment; and the design of a case (3d printed or laser cut) to encapsulate a USB enabled micro-controller; and a scheme to ensure the academic integrity is maintained for in-person, hybrid and fully online classes.

According to reports from comScore [1], 47% users in the United States (aged more than 13) are using a smartphones as their primary phone. Smartphone offers more advanced computing ability and connectivity than contemporary phones. In today’s world, a user wants to keep their smartphones private, because of the personal information present in it. Among these users, some of them are minors. This thesis addresses the functionality to track/control the mobile activities of minors by their parents using mobile phones. As a parent they want to know, whom his/her child is talking to and for what they are accessing browser for. Cellular network companies are providing number blocking services from the carrier side, but those are monthly paid services. In this thesis, we propose application architecture for remotely control the child phone and grant access to selected numbers for call and text. We use the emerging Android mobile platform and Google nexus phones to implement and test the application. This architecture will help developers to make more innovative applications in future which helps parent to access child phone information. We performed a study and reported the result using the proposal.

Show moreThermal remote sensing is a powerful tool for measuring the spatial variability of evapotranspiration due to the cooling effect of vaporization. The residual method is a popular technique which calculates evapotranspiration by subtracting sensible heat from available energy. Estimating sensible heat requires aerodynamic surface temperature which is difficult to retrieve accurately. Methods such as SEBAL/METRIC correct for this problem by calibrating the relationship between sensible heat and retrieved surface temperature. Disadvantage of these calibrations are 1) user must manually identify extremely dry and wet pixels in image 2) each calibration is only applicable over limited spatial extent. Producing larger maps is operationally limited due to time required to manually calibrate multiple spatial extents over multiple days. This dissertation develops techniques which automatically detect dry and wet pixels. LANDSAT imagery is used because it resolves dry pixels. Calibrations using 1) only dry pixels and 2) including wet pixels are developed. Snapshots of retrieved evaporative fraction and actual evapotranspiration are compared to eddy covariance measurements for five study areas in Florida: 1) Big Cypress 2) Disney Wilderness 3) Everglades 4) near Gainesville, FL. 5) Kennedy Space Center. The sensitivity of evaporative fraction to temperature, available energy, roughness length and wind speed is tested. A technique for temporally interpolating evapotranspiration by fusing LANDSAT and MODIS is developed and tested. The automated algorithm is successful at detecting wet and dry pixels (if they exist). Including wet pixels in calibration and assuming constant atmospheric conductance significantly improved results for all but Big Cypress and Gainesville. Evaporative fraction is not very sensitive to instantaneous available energy but it is sensitive to temperature when wet pixels are included because temperature is required for estimating wet pixel evapotranspiration. Data fusion techniques only slightly outperformed linear interpolation. Eddy covariance comparison and temporal interpolation produced acceptable bias error for most cases suggesting automated calibration and interpolation could be used to predict monthly or annual ET. Maps demonstrating spatial patterns of evapotranspiration at field scale were successfully produced, but only for limited spatial extents. A framework has been established for producing larger maps by creating a mosaic of smaller individual maps.

Between 1963 and 1976, 244 km$\sp2$ of forest (approximately a quarter of the study area) were converted to agricultural and other land uses, an apparent deforestation rate of 19 km$\sp2$/yr or approximately 1,872 ha/yr. The method entailed the cutting and weighing of strips of Mylar overlays. Despite the photogrammetric limitations, the results demonstrate an economical and practical technique that is readily applicable to developing countries. The potential of other remote sensing systems and the application of change detection techniques such as digital image subtraction to monitor deforestation is detailed.
