The main goal of this research has been to investigate elderly people's needs, perceptions, fears, hopes, and expectation regarding elderly care, including ethical issues linked to assistive technologies. As faith seems to take an important place in how some elders face the aging process, the spiritual dimension was also included. Therefore, the research was conducted among 15 church congregants. Results show that most respondents fear the physical and mental decay due to aging, often resulting in becoming a burden to someone else, along with abandonment and lack of financial resources. Most ethnic groups perceive that other cultures take better care of their elders than their own. Faith seems to offer a great support, as it gives the confidence that divine power will always be there for them even beyond death. The respondents in this research suggest that guidance should be provided in a more structured way, more focus should go on the youth and the elderly, more activities should be organized and practical information should be shared. Regarding the ethical issues of assistive technologies, they are not well informed about their possibilities but acknowledge their potential usefulness, combined with human care. They don't want technology to be too intrusive in …

A brief reading assessment and preference assessment were conducted with three participants with developmental and learning disabilities (i.e., two participants were diagnosed with Autism, the third participant was diagnosed with intellectual disability) who did not acquire fluent reading in previous individualized instruction. The results of the brief reading assessment were analyzed in an alternating treatment design and a preference assessment was conducted to determine the participants' preferred reading intervention. Following the results of the two assessments, a reading intervention that matched effectiveness with preference when possible or favored effectiveness when a match was not possible. The selected interventions (and later combined interventions) were implemented for each participant using an A-B-A-C or an A-B-A-C-D design. The results suggest that the four reading strategies are effective options for improving reading fluency. Also, a brief reading assessment can help identify an effective reading strategy. The results are discussed in the context of fluency gains, limitations, and implications for future research.

The goal of this study was to build on the historic use of the avian model of development and also to further the knowledge of autonomic nervous system (ANS) regulation of cardiovascular function in vertebrates. Vasoactive drugs sodium nitroprusside, a vasodilator and phenylephrine, a vasoconstrictor were used to study the correlation of cardiovascular function relationship with nerve activity, both sympathetic and parasympathetic (vagal). Additionally, ANG II was used to assess its effects on vagal inhibition. The present study shows that pharmacologically-induced hypertension is associated with a fall in mSNA, indicating that the capacity for sympathetic autonomic cardiovascular regulation is established by late incubation however, late-stage embryonic chickens did not show a significant increase in mSNA during hypotension. The hypotensive response of the embryo was not accompanied by the expected inhibition of vagal discharge; however a slight but insignificant reduction in vagal discharge was noted. When vagal efferent output was isolated, a significant drop in vagal efferent activity was noted in response to hypotension. The present study showed late-stage embryonic chickens lack a vagal response to hypertension in both efferent and sensory limbs. In this study, vagal discharge was reduced from baseline levels in response to Ang II. Collectively, the present …

This thesis presents qualitative research conducted in summer 2017 at the Finger Lakes Free Clinic, which provides free medical and holistic care to people without insurance in upstate New York. The primary goal of this research was to strengthen the relationship between a free clinic and its donors by gathering donor concerns and perceptions regarding federal healthcare policy. Data from 32 interviews with donors, staff, board members, and volunteers, along with 100 hours of participant observation revealed that donors to this clinic were concerned about the potential impact of Congressional healthcare reform yet did not consider federal policy a strong influence on their donations. Rather, donors cited dedication to local giving and personal connections with the clinic as their primary motivations. These motivations suggest the value of viewing the clinic-donor relationship as a relationship of reciprocity. From this framework, the research identifies opportunities for the clinic to reciprocate donor generosity while expanding services in response to a growing need. Insights from the research will guide the clinic's response to federal policy changes and support the clinic's vision of becoming a national model for integrative care.

The Chief Security Officer Problem (CSO) consists of a CSO, a group of agents trying to communicate with the CSO and a group of eavesdroppers trying to listen to the conversations between the CSO and its agents. Through Lemmas and Theorems, several Information Theoretic questions are answered.

The token economy is a widely used and versatile motivational system within applied behavior analysis. Moreover, token reinforcement procedures have been shown to be highly effective in the treatment of children with autism spectrum disorder (ASD). In the experimental analysis of behavior, token reinforcement contingencies are conceptualized as three interconnected schedule components: (1) the token-production schedule, (2) the exchange-production schedule, and (3) the token-exchange schedule. Basic work with nonhuman subjects has demonstrated that the exchange-production schedule is the primary driver of performance in these arrangements, and that variable-ratio exchange-production results in reduced pre-ratio pausing and greater overall rates of responding relative to fixed-ratio exchange-production schedules. However, little applied research has been conducted to assess the generality of these findings within applied settings. The purpose of this study was to determine if fixed- and variable-ratio token exchange-production schedules would exert differential effects on pre-ratio pausing and overall rates of responding for three children with ASD during a free-operant sorting task. The results showed that pre-ratio pausing and overall rates of responding were not differentially effected by the fixed- and variable-ratio exchange-production schedules. Discrepancies between the experimental work and the current study are discussed along with additional limitations.

Modern advances in technology have allowed for an increase in the precision with which we are able to measure, record, and affect behavior. These developments suggest that the domains in which behavior analysis might contribute are considerably broader than previously appreciated, for instance the area of behavioral medicine. One way the field of behavior analysis can begin to address problems in behavioral medicine is with biosensor technology, like surface electromyography (sEMG). For sEMG technology to be useful in behavioral medicine, specifically recovery from total knee arthroplasty, a reference value (the maximum voluntary individual contraction-MVIC) must be established. The MVIC value allows for the comparison of data across days and may allow the programming of contingencies. However, current MVIC methods fall short. Study 1 compares MVIC values produced by a participant given the typical instruction only method with two alternative methods: instruction + feedback, and instruction + feedback in a game context. Across 10 participants both feedback conditions lead to higher MVIC values then the instruction only condition. Study 2 applies the MVIC techniques developed during Study 1 to an exercise procedure. Using an MVIC value as the criteria for feedback Study 2 compares the same three conditions, however this time …

Very few studies have investigated how psychopathic traits might contribute to our understanding of prejudicial attitudes. Moreover, previous studies involve a number of limitations which cloud interpretation of their findings. The current study examined the relationship between prejudice and a number of its predictors (e.g., social dominance orientation (SDO) and right-wing authoritarianism (RWA)), while also including psychopathic traits and an innovative new measure of empathy using an online sample. A path analytic framework was employed to comprehensively model relations among psychopathic traits, SDO, RWA, and affective empathy domains in the prediction of generalized prejudice. Overall, there was support for certain psychopathic traits being modest predictors of racial prejudice, although more proximal measures were much stronger predictors. The results revealed a number of novel relationships that may help in further understanding the links between psychopathic propensities, empathy, and social-cognitive variables predictive of racial prejudice.

The world is getting busier and more crowded each year. Due to this fact resources such as public transport, available energy, and usable space are becoming congested and require vast amounts of logistical support. As of February 2018, nearly 95% of Americans own a mobile cell phone according to the Pew Research Center. These devices are consistently broadcasting their presents to other devices. By leveraging this data to provide occupational awareness of high traffic areas such as public transit stops, buildings, etc logistic efforts can be streamline to best suit the dynamics of the population. With the rise of The Internet of Things, a scalable low-cost occupancy monitoring system can be deployed to collect this broadcasted data and present it to logistics in real time. Simple IoT devices such as the Raspberry Pi, wireless cards capable of passive monitoring, and the utilization of specialized software can provide this capability. Additionally, this combination of hardware and software can be integrated in a way to be as simple as a typical plug and play set up making system deployment quick and easy. This effort details the development and integration work done to deliver a working product acting as a foundation to build …

The ways that people use libraries have changed drastically over the past few decades. Proliferation of computers and the internet have led to the purpose of libraries expanding from being only places where information is stored, to spaces where people teach, learn, create, and collaborate. Due to this, the ways that people occupy the space in a library have also changed. To keep up with these changes and improve patron experience, institutions collect data to determine how their spaces are being used. This thesis involves the development a system that collects, stores, and analyzes data relevant to occupancy to learn how a space is being utilized. Data is collected from a temperature and humidity sensor, passive Infrared sensor, and an Infrared thermal sensor array to observe people as they occupy and move through a space. Algorithms were developed to analyze the collected sensor data to determine how many people are occupying a space or the directions that people are moving through a space. The algorithms demonstrate the ability to track multiple people moving through a space as well as count the number of people in a space with an RMSE of roughly 0.39 people.

Having a measurable way to analyze how staff members describe teaching interactions is important for staff training and building a community of effective and caring practice. The purpose of this project, part of a larger program, is to develop a measurement system that captures descriptions of connected events (narratives) during teaching interactions. This project involved development of a reliable measurement system that discriminates between experienced and novice narratives of teaching interactions (contingency arrangements) across multiple cases of instruction. The participants were employees of a non-profit agency serving children with autism and their families. They volunteered to participate in the study. The development of the code included the systematic selection of high quality autism intervention video clips and asking participants to view the clips and describe events, and then coding responses. The participant narratives were then categorized by themes and analyzed. The results are described in the context of usefulness and limitations of the measurement systems. A mutielement design comparing responses across stimulus conditions was used to evaluate the sensitivity of the measurement system in discriminating between novice and experienced interventionists.

The quality of care of residents in nursing homes receive is an important issue facing our society, and reliable methods to assess and measure important indicators of quality of care are necessary to ensure that nursing homes are providing adequate services. Previous researchers have developed methodologies to evaluate indicators of quality of care, including environmental conditions, resident conditions, resident activities, and staff activities using momentary-time sampling procedures across a variety of settings and populations. The purpose of the present study was to replicate and extend the time-sampling methodology used in previous research in two units in a nursing home.

This work addresses hurricane preparedness in Escambia County, Florida. It explores preparing for hurricanes as an informal learning process occurring within personal networks and embedded in beliefs, values, and attitudes. Findings reveal that participants learned to prepare from their parents in childhood and improved upon that knowledge through direct experience in adulthood. Later, they passed this knowledge on to their children as well as co-workers. These preparations are embedded in beliefs of self-determination and attitudes of endurance. However, this body of knowledge and their respective practices are not equally accessible to all. Recommendations are provided so local organizations can incorporate local knowledge and practices with preparedness improvement efforts and foster social cohesion as well.

Solutions journalism, rigorous reporting on responses to social problems, has gained great traction in the last decade. Using positive psychology theory, also known as the theory of well-being, this qualitative study examines the impact of reporting while using solutions journalism techniques. Applying the five pillars of positive psychology theory: positive emotion, engagement, positive relationships, meaning and accomplishment (PERMA), this study used interviews and content analysis to investigate how journalists are applying the tools of solutions journalism as well as what they hope to accomplish in the process. Findings revealed that the application of solutions journalism techniques produces hope and community engagement resulting in flourishing and positive change for individuals, communities and all involved in the reporting process.

In the first part of this thesis, we propose a distributed consensus algorithm under multi-layer multi-group structure with communication time delays. It is proven that the consensus will be achieved in both time-varying and fixed communication delays. In the second part, we study the distributed optimization problem with a finite-time mechanism. It is shown that our distributed proportional-integral algorithm can exponentially converge to the unique global minimizer when the gain parameters satisfy the sufficient conditions. Moreover, we equip the proposed algorithm with a decentralized algorithm, which enables an arbitrarily chosen agent to compute the exact global minimizer within a finite number of time steps, using its own states observed over a successive time steps. In the third part, it is shown the implementation of accelerated distributed energy management for microgrids is achieved. The results presented in the thesis are corroborated by simulations or experiments.

We evaluated the effects of an instructional package on the emergence of novel intraverbals in children diagnosed with autism. Participants were two boys with a diagnosis of autism who had tact and listener repertoires for common objects and events, some intraverbal responses, and showed an ability to learn new intraverbal responses through direct instruction prior to participating in the study. Tact training, listener training, sorting training, and mixed training (listener and tact training) were conducted with each participant, with a probe to test for emergent intraverbals following each training step. If some emergence was seen during a probe following a training step, probes were conducted with the remaining sets to test for emergence in those sets as well. Multiple-exemplar training was conducted following the training steps if all targets within a set did not meet the criterion for emergence during probes. Results showed that for one participant, all four training steps, in addition to multiple-exemplar training, were needed to see emergence in all targets during probes for two sets, with the last two sets requiring only tact training before all targets had emerged during probes. The second participant required only tact training during three sets, with listener training required for …

Research has shown that well-trained staff within early and intensive behavioral intervention (EIBI) provide more effective treatment. An important part of training is learning the vocabulary and concepts of treatment. This aids in conceptual understanding of the principles and procedures. The process of learning behavioral concepts also develops the necessary verbal repertoire needed to communicate among members of a community of practice; a group of people who have common reinforcers and are working toward a common goal. Learning to tact a series of sequential descriptions, or verbally narrate, exemplary teaching interactions should be a goal when teaching behavior analysis because it is how we, as a community, interact and establish an understanding of behavior analysis. The purpose of the current study is to train novice behavior analysts to narrate exemplary intervention sequences that are responsive, flexible, and effective teaching interactions. The effects of the training were evaluated using a multiple baseline design across training conditions, replicated across 3 participants. The results suggest that the training was effective in increasing the number of narrative statements as well as the number of narrative statements related to five critical features of a teaching interaction and the relations between those features. The results are …

This study aims to examine the motivation, experience and benefits of Nepalese domestic tourists visiting the seismic memorial sites after the 25 April 2015 earthquake (known as Gorkha earthquake). A total of 403 surveys was gathered from seismic sites of Nepal (Kathmandu, Bhaktapur and Patan). Data were tested to analyze why the tourists are interested in disaster sites and how their experience during their visit impact the benefits of the visits. Additionally, partial least square structural equation modeling (PLS-SEM) was employed to test the relationships among tourist motivations, experiences, and perceived benefits at the dark tourism sites in Nepal. Among the five motivational factors discovered, the empirical results depict that emotional reaction is the strongest factor of the dark tourism motivation, affecting both cognitive and affective experiences. Additionally, this study confirms that cognitive experience is more influenced by dark tourism motivations than affective experience. Among the four experience factors examined in the study, self-reflection is found to have the strongest impact of three aspects of perceived dark tourism benefits, such as knowledge gain, fulfillment, and appreciation. Overall, the findings of the study provide important implications to the management sectors of dark tourism sites, enhancing the importance of providing cognitive experiences …

Forging Their Legacy: Cooperation and Accommodation in the Lower Rio Grande Valley is an examination of the relationships created during the mid-nineteenth century between Anglo and Tejano elites in the five counties that make up the Lower Rio Grande Valley. Conducted through a quantitative lens, the five-chapter study seeks to demonstrate that, although the period between 1848 and 1870 was fraught with conflict and violence, the Anglo and Tejano elite of the Lower Rio Grande Valley came together in cooperation in order not only to survive these troubling times but to prosper. The thesis begins by identifying and analyzing the economic and political elite in the Lower Rio Grande Valley during the 1850s. A new crop of Anglo immigrants arrived with the Mexican-American War, but only a small number willing to assimilate to local Tejano culture were able to leave their mark on the Lower Valley. Chapter 4 relates the effect of the Civil War on the elite of the Lower Valley. It explores the profitable cotton trade during the war and the struggle that both Anglo and Tejano elites faced during Reconstruction. The thesis concludes with a macro-analysis of the twenty-two-year period from 1848-1870. It summarizes overall trends found …

An environmentally friendly, and contamination free process for etching and cleaning semiconductors is critical to future of the IC industry. Under the right conditions, water has the ability to meet these requirements. Water becomes more reactive as a function of temperature in part because the number of hydronium and hydroxyl ions increase. As water approaches its boiling point, the concentration of these species increases over seven times their concentrations at room temperature. At 150 °C, when the liquid state is maintained, these concentrations increase 15 times over room temperature. Due to its enhanced reactivity, high temperature water (HTW) has been studied as an etch and clean of thermally grown SiO2, Si3N4, and low-k films. High temperature deuterium oxide (HT-D2O) behaves similarly to HTW; however, it dissociates an order of magnitude less than HTW resulting in an equivalent reduction in reactive species. This allowed for the effects of reactive specie concentration on etch rate to be studied, providing valuable insight into how HTW compares to other high temperature wet etching processes such as hot phosphoric acid (HPA). Characterization was conducted using Fourier transform infrared spectroscopy (FTIR) to determine chemical changes due to etching, spectroscopic ellipsometry to determine film thickness, profilometry to …

This thesis aims to increase photovoltaic (PV) panel power efficiency by employing a cooling system based on water circulation, which represents an improved version of water flow based active cooling systems. Theoretical calculations involved finding the heat produced by the PV panel and the circulation water flow required to remove this heat. A data logger and a cooling system for a test panel of 20W was designed and employed to study the relationship between the PV panel surface temperature and its output power. This logging and cooling system includes an Arduino microcontroller extended with a data logging shield, temperature sensing probes, current sensors, and a DC water pump. Real-time measurements were logged every minute for one or two day periods under various irradiance and air temperature conditions. For these experiments, a load resistance was chosen to operate the test panel at its maximum power point. Results indicate that the cooling system can yield an improvement of 10% in power production. Based on the observations from the test panel experiments, a cooling system was devised for a PV panel array of 640 W equipped with a commercial charge controller. The test data logger was repurposed for this larger system. An identical …

Behavior-specific praise has been shown to increase rate of desired behaviors for individuals with intellectual and developmental disabilities, though it is rarely used by caregivers in residential facilities for adults with disabilities. Prompting in the form of tactile stimulation has been demonstrated to increase rate of behavior-specific praise delivered by teachers and caregivers. The purpose of the current study was to increase the quantity and quality of behavior-specific praise statements that were delivered by caregivers to individuals at a large residential facility for adults with disabilities. A tactile prompting device (Gymboss Interval Timer and Stopwatch) was provided to the caregivers and set to vibrate for one second at intervals of five minutes, for a total of six intervals. Instructions were provided to the caregivers to deliver behavior-specific praise statements, for appropriate behaviors, to their assigned clients every time a vibration occurred. Examples of behavior-specific praise statements were provided to the caregivers before each session, but no feedback was delivered during the prompting phase. Results indicated that a tactile prompting device was effective at increasing rate of behavior-specific praise statements delivered by caregivers in as little as one session.

Falk's pivotal 1961 study showed that rats would drink excessive amounts of water when exposed to a time based schedule of reinforcement. Since then, schedule-induced drinking or polydipsia, has been demonstrated with several species and with a variety of different behaviors. Rats, the most commonly used animal, have been shown to drink excessive amounts of water under a variety of different time based schedules of reinforcement; exclusively during a free operant procedure. The current study shows that water drinking can be induced during a discrete trial procedure, and instead of using a time-based schedule of reinforcement, this study used a variable-ratio schedule of reinforcement. The results showed that excessive water drinking was induced under these conditions with a canine.
