Influenza is responsible for 20,000 deaths per year in the United States, with adults 65 and older accounting for most of these deaths. In this qualitative study, ten Haitian elders were interviewed in Creole and data were hand-written and simultaneously translated in English, to better understand their health beliefs regarding influenza immunizations.

Show moreInfluenza is responsible for 20,000 deaths per year in the United States, with adults 65 and older accounting for most of these deaths. In this qualitative study, ten Haitian elders were interviewed in Creole and data were hand-written and simultaneously translated in English, to better understand their health beliefs regarding influenza immunizations. Purnell's model (1998) of Cultural Competence was utilized as organizing framework for description of the sample, analysis and discussion. Several themes emerged during thematic analysis of the participants' responses. Participants identified influenza as a "big cold" which can initially be prevented with traditional home remedies and practices as well as with prayers. Lack of knowledge of the vaccine, uncertainty of the effectiveness of the vaccine, reliance on the recommendations of their children, doctors, and as well as the researcher, and lack of access were all factors reported as affecting their acceptance of the vaccine.

Show moreThis dissertation examines the teaching of environmental awareness in Peru's public educational system and how it needs to be consciously taught and improved in order to overcome contamination and pollution of resources and decrease poverty. This is a situation afflicting a significant percentage of Peruvians, who face difficulty in surviving and living well because the scarcity of clean air and water, unpolluted land, and affordable energy, which are basic environmental resources. The teaching of environmental awareness, as mandated by Educational Peruvian Laws and curriculum, should be redesigned to promote environmental ethical awareness and sustainability to guard Peru's natural and cultural resources, bounty and beauty before it is too late. In this way, education will promote a better level of life for the majority of Peruvians. Peruvian public education is presently in a state of emergency, as has been recognized by the former minister of education Javier Sota Nadal (2004-2006). Only 1 0% of students leaving high school understand what they read and only 4% do well in mathematics. A number of reasons contribute to this tragedy. Among them is principally the low quality of teaching and the inadequate budget available for public education. Peru's laws, echoing the Universal Declaration of Human Rights, and mandate good and free education and guarantee the right to live well. The reality is that none of these rights are properly given to the majority of poor Peruvians. This dissertation offers a course of action to teach and spread out not only environmental awareness, but also environmental ethics and sustainability from a personal perspective. This rounded concept, if applied, will form citizens able to guard, protect, and preserve natural and cultural resources. The needed environmental ethics and sustainability education will gradually guarantee, from early in life, a truthful way to love, care, protect and preserve the ecosystem. Also encompassed within this concept is to positively influence the behavior of professionals, economists, politicians, and citizens. It envisions interconnectedness between humans and the environment based on the teaching of environmental ethics and sustainability, educating children to develop critical thinking, and creativity, as well as adopting eco-design principles. This different approach could definitely better the new generation's contribution to preserve natural and cultural resources and to reduce poverty as well as contribute an example to other countries. Present and future Peruvian generations will be able to connect, care, protect, and sustain resources, so when it comes to sustainable development, they will be fully aware of the consequences of their actions toward the environment, themselves and their children's well being. In this way, education would truly fulfill its responsibility.

Show moreThe annihilation of women's artistic creativity in selected works by the Mexican writer Elena Poniatowska is a result of societal conditioning. Two short stories from Lilus Kikus and the short novel Querido Diego, te abraza Quiela portray the process of deterioration and demeaning obliteration of women's creative faculties, as they are conditioned to accept the conventional roles of wife and mother. Poniatowska's texts posit that, upon assuming these roles, the exercise of the creative artist's use of her imagination is postponed or detrimentally transformed forever. In the selected texts, women's artistic creativity is chronicled first at its best while the characters are girls or adolescents. The neglect, procrastination, and attention to domestic and repetitive tasks as opposed to the pursuit of their creative vein is observed in the adult women characters. Poignantly portrayed is Quiela, Diego Rivera's common-law wife of ten years, who destroys her life and creative power by trying to be the perfect wife. These literary works speak forcefully to the social issues and institutions that place women artists in a bind; are the roles of artist, mother/wife incompatible?

Show moreThe thesis describes the development of SoftBoard, a Web-based application sharing system. The main goal is to create a convenient tool for conducting virtual office hours for distance education over the Internet. It has been reported in the recent research papers that the current Internet is still not suitable for supporting collaborative tools such as audio/video conferencing and some advanced application sharing features as proclaimed by developers. However the Internet can be used to a lesser degree to fulfill needs of smaller application sharing systems which are not very network bandwidth intensive. SoftBoard is designed to be used over today's Internet, and can be easily invoked from a standard Web browser. It is developed in Java and is implemented using Java's Remote Method Invocation (RMI) for networking. A light pen can be used with SoftBoard to provide a convenient way for creating non-textual contents free hand. The thesis is part of the ongoing research work at Florida Atlantic University's Center for Innovative Distance Education Technologies (CIDET). Research work has been done to validate the present Internet for its capabilities to hold a true distance education program using various available collaborative tools.

Human visual system is the ultimate receiver of compressed signal and final judge of its quality. This dissertation presents work towards optimal video compression algorithm that is based on the characteristics of our visual system. Modeling phenomena such as backward temporal masking and motion masking we developed algorithms that are implemented in the state-of- the-art video encoders. Result of using our algorithms is visually lossless compression with improved efficiency, as verified by standard subjective quality and psychophysical tests. Savings in bitrate compared to the High Efficiency Video Coding / H.265 reference implementation are up to 45%.

Show moreWith the increasing complexity of the system design, it has become very critical to enhance system design productivity to meet with the time-to-market demands. Real Time embedded system designers are facing extreme challenges in underlying architectural design selection. It involves the selection of a programmable, concurrent, heterogeneous multiprocessor architecture platform. Such a multiprocessor system on chip (MPSoC) platform has set new innovative trends for the real-time systems and system on Chip (SoC) designers. The consequences of this trend imply the shift in concern from computation and sequential algorithms to modeling concurrency, synchronization and communication in every aspect of hardware and software co-design and development. Some of the main problems in the current deep sub-micron technologies characterized by gate lengths in the range of 60-90 nm arise from non scalable wire delays, errors in signal integrity and un-synchronized communication. These problems have been addressed by the use of packet switched Network on Chip (NOC) architecture for future SoCs and thus, real-time systems. Such a NOC based system should be able to support different levels of quality of service (QoS) to meet the real time systems requirements. It will further help in enhancing the system productivity by providing a reusable communication backbone. Thus, it becomes extremely critical to properly design a communication backbone (CommB) for NOC. Along with offering different levels of QoS, CommB is responsible directing the flow of data from one node to another node through routers, allocators, switches, queues and links. In this dissertation I present a reusable component based, design of CommB, suitable for embedded applications, which supports three types of QoS (real-time, multi-media and control applications).

Show moreThere is a mushrooming demand for battery operated applications that require intensive computation in portable environments. This has motivated the research and development of techniques that reduce power in CMOS digital circuits while maintaining their computational throughput. The two essentials to achieve a low power design are miniaturization and long battery life. Lowering the supply voltage is one of the most effective ways to achieve low-power performance as power dissipation in digital CMOS circuits is approximately proportional to the square of supply voltage. The basic idea behind this thesis is that it proposes new designs of transfer gate based logical circuits, which use lower supply voltage and less number of transistors than the conventional designs. This work evaluates the obtained results from the proposed designs of the low-power ALU with that from the standard CMOS, other low power designs namely, Wang's XOR, XNOR and Inverter based gates. It was observed that the proposed designs perform better in terms of power consumption than the standard CMOS designs, and the other low power designs mentioned above.

Show moreA "hybrid" telerobotic simulation system that is suitable for telemanipulation rehearsal, operator training, human factors study and operator performance evaluation has been developed. The simulator also has the capabilities for eventual upgrade for supervisory control. It is capable of operation in the conventional rate-control, master/slave control and a data driven preprogrammed mode of operation. It has teach/playback capability which allows an operator to generate joint commands for real time teleoperation. For high-level task execution, the operator selects a specific task from a set of menu options and the simulator automatically generates the required joint commands. The simulator was developed using a three dimensional graphic model of an increasingly popular manipulator, TITAN 7F. A closed-form solution for inverse kinematics of the manipulator was found. Degeneracies from inverse kinematics solutions were observed to exist for certain arm configurations, although the manipulator can physically attain such configurations. An approach based on known facts about the manipulator geometry and physical constraints coupled with heuristics was used to generate physically attainable joint solutions from the inverse kinematics. The conditions that cause solution degeneracy were demonstrated to be related to singularity conditions. A novel object interaction detection strategy was implemented for more realistic telemanipulation. The object detection technique was developed based on the use of superellipsoid, which has a convenient inside-outside function for interference testing. The manipulator, with its end-effector and payloads, if any, were modeled as superquadric ellipsoids. A systematic way of determining transformation matrices between the superquadric manipulator links was developed. The interaction detection technique treats both moving and stationary objects in a consistent manner and has proved to be easy to implement and optimize for real-time applications. The feature has been applied for the simulation of pick-and-place operations and collision detection. It is also used to provide visual feedback as a low-cost force reflection and can be interfaced with a bilateral controller for force reflection simulation.

Show moreA VLSI implementable feature extraction scheme, and two VLSI implementable algorithms for feature classification that should lead to a practical handwritten digit recognition system are proposed. The feature extraction algorithm exploits the concept of holon dynamics. Holons can be regarded as a group of cooperative processors with self-organizing property. Two types of artificial neural network-based classifiers have been evolved to classify these features. The United States Post Office handwritten digit database was used to train and test these networks. The first type of classifier system used limited interconnect multi-layer perceptron (LIMP) modules in a hierarchical configuration. Each classifier in this system was independently trained and designated to recognize a particular digit. A maximum of sixty-one digits were used to train and 464 digits which included the training set were used to test the classifiers. A cumulative performance of 93.75% (correctly recognized digits) was recorded. The second classifier system consists of a cluster of small multi-layer perceptron (CLUMP) networks. Each cell in this system was independently trained to trace the boundary between two or more digits in the recognition plane. A combination of these cells distinguish a digit from the rest. This system was trained with 1796 digits and tested on 1918 different set of digits. On the training set a performance of 95.55% was recorded while 79.35% resulted from the test data. These results, which are expected to further improve, are superior to those obtained by other researchers on the same database. This technique of digit recognition is general enough for application in the development of a universal alphanumeric recognition system. A hybrid VLSI system consisting of both analog and digital circuitry, and utilizing both Bi-CMOS and switched capacitor technologies has been designed. The design is intended for implementation with the current MOSIS 2 $\mu$m, double poly, double metal, and p-well CMOS technology. The integrated circuit is such that both classifier systems can be realized using the same chip.

Show moreThe complex problems of the twenty-first century cannot be effectively addressed with twentieth century top-down bureaucratic governance alone because of limited stakeholder participation in collective decision making and/or implementation. The somewhat limited stakeholder participation in the policy process, especially, that of target populations, can impact generating viable solutions to complex problems. Collaborative governance has emerged as a promising alternative to traditional management in addressing contemporary complex problems. Collaborative governance is thus a type of governance that promotes joint participation of state and non-state stakeholders in decision making and/or implementation by using agreed upon processes of engagement to collectively address problems. Such governance is especially beneficial for addressing the challenges posed by the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). This dissertation uses the collaborative governance concept to explicate the efforts of HIV Health Services Planning Councils in Broward County and Palm Beach County of South Florida with the purpose of accentuating how collaborative governance works in providing various categories of services to meet the needs of people with AIDS (PWAs), as part of the implementation of the Ryan White CARE Act. The study focuses on critical variables of collaborative governance such as facilitative leadership and institutional design, the collaborative process variables such as trust building, commitment to the process and shared understanding, and outputs such as allocation priorities of the Councils. This study employed mixed methods in collecting data from various relevant sources., The combined findings from surveys, interviews, observations and document reviews were essential to knowledge and understanding of collaborative governance of the respective Councils. The results revealed more similarities than differences between the Councils in their efforts towards addressing the HIV/AIDS problem. The Councils are similar in all variables of collaborative governance with few exceptions relative to facilitative leadership and institutional design. The differences were relative to membership, number of committees, amount allocated for various service categories and number of clients served. Furthermore, the Councils were slightly different in reaching consensus on subjects of deliberation. On the average, Palm Beach County's Council make decisions by consensus relatively easily when compared with the Broward County's Council. Nonetheless, both Councils are consensus-oriented and strive to make decision by consensus as evidenced by unanimous votes or simple majority votes on various subjects of deliberation. In addition, representation and participation of target populations in collaborative governance have contributed to the empowerment of those target populations. The study contributes to the literature by developing a conceptual model for HIV/AIDS collaborative governance for producing outputs to help meet needs of target populations. Also, the study contributes to collaborative governance theorizing by drawing a nexus between variables of collaborative governance and by complementing the existing non-linear perspective of collaborative process for collective problem solving. Collaborative governance involving state and non-state stakeholders thereby enhances efforts of public managers by harnessing resources to effectively manage and/or address complex problems for the benefit of society.

Participants were taught to decline, block and report when they received a lure from someone that they do not know. A multiple baseline design across lures demonstrated the effects of the intervention on participant performance. Results confirmed an increase in social media safety skills performed by all participants. Participants were able to maintain this skill set once the training package was removed. Spontaneous generalization was demonstrated by all participants for some lures. Generalization of social media safety skills was demonstrated across participants in a setting where they did not receive instruction. Limitations and implications for future research are discussed.

Show moreRecognized leadership skills generally include communication skills and public speaking ability. Some children develop leadership and public speaking skills early in life. Some high schools and colleges emphasize public speaking. Adults frequently enroll in seminars such as Dale Carnegie programs or join organizations such as Toastmasters International. The researcher's own years of teaching and speaking experience have led her to believe in the potential value of public speaking for children, adults, and leaders in education organizations. Principals must speak competently and professionally. The purpose of this study was to determine how and when secondary school principals learned public speaking skills. The research also assessed their public speaking involvement and the importance they placed on public speaking for themselves, their staff, and their students. The researcher developed a questionnaire which was distributed to 101 middle and high school principals in Broward and Palm Beach county school districts in Florida. Completed responses were received from 52 principals. The most frequently cited-preparations for public speaking were college and high school courses. Public speaking skills were learned during high school and college years for 32 respondents. Only two had taken a Carnegie or Toastmasters course. Six principals said Carnegie or Toastmasters Youth Leadership type programs were offered in their schools, but 33 said they would be interested or wanted additional information. The principals most often cultivated public speaking skills by encouraging teachers to invite students to speak in class, inviting teachers and students to speak at assemblies, or by having drama clubs or debate teams. The last question was, "How important is public speaking in what you do today?" Very important was checked by 48 principals; somewhat important was checked by the remaining four respondents. The researcher believes that public speaking should be cultivated at all levels of education. Future research may consider whether resiliency of at-risk students could be enhanced by offering formal training in public speaking. The findings support the researcher's hypothesis that if school administrators recognize the importance of public speaking in their own experience, they are more likely to support its development among staff and students.

Show moreTraumatic Brain Injury (TBI) is a disability resulting in functional impairments and heightened dependence on others. Family members of persons with TBI can assume added responsibilities during the adjustment to the disability and rehabilitation process, placing strain on the family system. Community re-integration is a primary goal of the rehabilitation process for persons with TBI as this is a step in developing autonomy and promoting independence and productive activity throughout different areas of the person's life (e.g., work, social networks, and home life). This study was designed to examine predictors of community re-integration outcomes of TBI survivors and empirically test the resiliency model of family stress, adjustment, and adaptation while incorporating family needs by surveying caregiving family members. Specific aims of the study include validating relationships of the resiliency model with individual and family outcomes in adaptation and supporting future recommendations for healthcare providers working with families with members with TBI.

Show moreThis report describes the development of a low cost open source semiautonomous robotic car and a way to communicate with it. It is a continuation of prior research done by other students at FAU and published in recent ASEE conferences. The objective of this project was the development of a new robotic platform with improved precision over the original, while still keeping the cost down. It was developed with the aim to allow a hands-on approach to the teaching of mathematics topics that are taught in the K-12 syllabus. Improved robustness and reliability of the robotic platform for visually solving math problems was achieved using a combination of PID loops to keep track of distance and rotation. The precision was increased by changing the position of the encoders to the shafts of each motor. A mobile application was developed to allow the student to draw the geometric shapes on the screen before the car draws them. The mobile application consists of two parts, the canvas that the user uses to draw the figure and the configure section that lets the user change the parameters of the controller. Results show that the robot can draw standard geometric and complex geometric shapes. It has high precision and sufficient accuracy, the accuracy can be improved with some mechanical adjustments. During testing a Pythagorean triangle was drawn to show visually the key mathematics concept. The eventual goal of this project will be a K-12 class room study to obtain the feedback of the teachers and students on the feasibility of using a robotic car to teach math. Subsequent to that necessary changes will be made to manufacture a unit that is easy to assemble by the teacher.
