Training parents of a child with autism to increase the frequency of their child's social behavior may improve the quality of parent-child interactions. The purpose of this methodological study was to develop a direct observation method for rapidly sampling social harmony between parents and their toddlers with autism during parent training interactions. The current study used a pre and post probe design, with benchmark comparisons to test the discriminability of the measurement protocol across two sets of data. The first set of data came from pre and post training videos from a parent training program for children with a diagnosis of autism or at risk for a diagnosis. The second set of data came from videos of typically developing toddlers and their parents. The results of the study show that the measurement system differentiated in the level of harmonious engagement between the benchmark sample and the sample including children diagnosed with autism. The results are discussed in the context of future directions and the utility of the measurement system for behavior analytic practices in parent training and other settings where rapport and complex interactional behaviors are an intervention priority.

Disabled veterans with post-traumatic stress disorder (PTSD) exist in a category separate from many civilians and soldiers. Their experiences land them in a category distinctly marked as atypical. The standard protocol to manage this atypical subject position is prescription drugs- a mark of the ill. In a distorted, post-war American society, what happens when veterans with PTSD refuse to be labeled as ‘sick,' ‘different,' or even ‘disabled'? This thesis explores the actions and intricacies of a community of veterans who advocate for medical cannabis to manage associated symptoms of PTSD. This group of veterans campaigns for individuality, both in medical treatment and in personal experience. Collaboratively, their experiential evidence indicates that none can be treated in the same fashion. After a year of participant observation and field work, it becomes apparent that their work both individualizes and unifies the veterans. This thesis details their experiences and the results of their activist campaign to demarcate themselves.

This thesis presents design and development of a gesture recognition system to recognize finger spelling American Sign Language hand gestures. We developed this solution using the latest deep learning technique called convolutional neural networks. This system uses blink detection to initiate the recognition process, Convex Hull-based hand segmentation with adaptive skin color filtering to segment hand region, and a convolutional neural network to perform gesture recognition. An ensemble of four convolutional neural networks are trained with a dataset of 25254 images for gesture recognition and a feedback unit called head pose estimation is implemented to validate the correctness of predicted gestures. This entire system was developed using Python programming language and other supporting libraries like OpenCV, Tensor flow and Dlib to perform various image processing and machine learning tasks. This entire application can be deployed as a web application using Flask to make it operating system independent.

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 …

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 …

The film captures an improvising musician and composer named Garrett Wingfield, who expresses spontaneous sound reflected in his mind, body and spirit. By working with his music friends, he releases his creative energies through his compositions and his different types of saxophones. The documentary allows its audience to experience the youth culture in a postmodern world.

This study examined a mediational model of mental illness stigma, parent-child communication about mental health concerns, and help seeking attitudes/behaviors among young adults with at least one immigrant parent while considering the possible moderating effect of acculturation gap. The primary goal of this study was to examine whether the acculturation gap changed the relation between mental illness stigma and communication about personal mental health concerns with immigrant parents, which in turn could become a significant predictor of their help-seeking attitudes, as well as a barrier to seeking professional mental health services. Findings provided support to the direct and indirect effects of mental illness stigma through communication about mental health concerns on attitudes about help-seeking. The acculturation gap hypothesized to be a possible moderator for the stigma-communication about mental health concerns relationship among young adult ABCI was found to be significant for ABCI with a low mainstream culture acculturation gap. Discussion on the findings, limitations of the study, future research directions, and counseling implications are addressed.

Retirement from elite sport can be highly distressing for athletes, and many athletes report elevated depression and anxiety or body dissatisfaction when going through this transition. Factors that may be important in determining a higher level of adjustment in retirement include feeling in control of when and how retirement occurs, planning occupationally for after sport, and having achieved sport goals. Thus, we examined how such factors related to former female collegiate athletes (N = 218) satisfaction with life, depression, and body satisfaction. Two to six years post retirement, athletes completed an online questionnaire that measured their satisfaction with life, depressive symptomatology, and body satisfaction; retirement factors were measured by the 12-items from the BALANCE scale. Through regression analyses, we examined the extent to which each of the 12 retirement factors is related to life satisfaction, depression, and body satisfaction; time since retirement was unrelated to these outcomes. Future research might address the transition immediately following retirement utilizing these factors that appear most influential.

Natural speech contains a wealth of information relevant to understanding cognitive and affective psychological processes, which are reflected in both prosodic and semantic channels of communication. While differences in semantic channels have been demonstrated among psychopathic versus non-psychopathic individuals, research on the role of prosody in psychopathy is scant. The Computerized Assessment of Natural Speech protocol provides adetailed assessment of macroscopic-level prosody variables related to underlying psychological processes that have been linked to psychopathological conditions. Psychopathy is a condition that involves a number of disruptions in cognitive and affective processes, which theoretically can be tied to various aspects of speech. The present study provides a novel contribution by examining natural speech output in an offender sample in the context of a clinical interview (Psychopathy Checklist – Revised). More specifically, the present study examined variance in prosody across segments of the PCL-R interview designed to elicit both positively and negatively valenced emotional content, across high and low levels of subjective arousal, in psychopathic (n = 49) and non-psychopathic (n = 44) male offenders who were similar in terms of age, education, race/ethnicity, and IQ. Three-factor mixed MANOVAs (Group x Valence x Arousal) were conducted to evaluate differences in prosodic speech displayed …

Many evangelical Christians distance themselves from the mainstream commercial culture, because they perceive mainstream media and popular culture to promulgate immoral messages through representations such as sex and violence. This disconnect from Hollywood have made evangelicals a tough audience to market. Sony, however, has been able to connect with the evangelical market by producing a line of contemporary Christian films through their in-house division Affirm Films. By prioritizing the narratives of their films Heaven is for Real, War Room, and Miracles From Heaven to focus on contemporary Christian characters, conflicts, and settings, Sony is able to attract the evangelical audience with films that align with their conservative belief system.

Intergroup relations and the factors affecting them constitute a subject of recurring interest within the academic community. Social identity theory suggests that group membership and the value we assign to it drives the expression of in-group favoritism and outgroup prejudice, among other intergroup phenomena. The present study examines how (ir)religious identities are related to topic-sentiment polarization in the form of positive in-group and negative outgroup bias during interreligious debates in YouTube commentaries. Drawing from the propositions of social identity theory, six hypotheses were tested. The data for the study, a product of a natural experiment, are comments posted on YouTube commentary sections featuring videos of interreligious debates between (a) Christian and atheist or (b) Christian and Muslim speakers. Using topic-sentiment analysis, a multistage method of topic modeling with latent semantic analysis (LSA) and sentiment analysis, 52,607 comments, for the Christian - atheist debates, and 24,179 comments, for the Christian - Muslim debates, were analyzed. The results offer support (or partial support) to the hypotheses demonstrating identity-specific instances of topic-sentiment polarization to the predicted direction. The study offers valuable insights for the relevance of social identity theory in real-world interreligious interactions, while the successful application of topic-sentiment analysis lends support for …

Although behavior analysts have studied the effects of motivation on preference assessments, consumer behaviorist have not. The purpose of this study was to analyze the effect of the temporary removal of a choice on the order and frequency of purchases after the candy returned. Seventy percent of the time the participant purchased the removed candy first and 60% of the time the participant purchased more than in the baseline.

Behavioral skills training (BST) is often used to train caregivers to implement various behavior management procedures; however, additional strategies are sometimes required to promote the generalization of skills from a contrived setting to the natural environment. Generalizing skills to the natural environment requires that the caregiver's behavior transfer from control of stimuli in the contrived setting to stimuli in the natural environment, and the skill continues to be performed with high levels of accuracy. The purpose of this study was to assess the extent to which caregivers generalized the use of social reinforcement, in the form of descriptive praise, from the contrived setting to the natural environment. When caregivers failed to respond to opportunities, a progressive prompt delay was used to bring caregivers' responding under the control of relevant client behavior; feedback was used to improve the accuracy with which caregivers implemented reinforcement. Five caregivers in a large residential facility participated in the study; single-opportunity probes were used to assess caregiver's identification of opportunities and accuracy in implementing reinforcement for two defined client behaviors, compliance and appropriate attention-getting behavior. Results of the study suggest that skills failed to generalize from the contrived setting to the natural environment. However, prompting was …

With his car clad in flat-earth messages, he travels around the country provoking discussions with curious bystanders and debating scientists. While he thrives in this pursuit, it is not without its costs.

In this thesis, I analyze some of the most important contributions concerning the inclusion of animals in the moral and political sphere. Moving from these positions, I suggest that a meaningful consideration of animals' sentience demands a profound, radical political theory which considers animals as moral patients endowed with specific capabilities whose actualization needs to be allowed and/or promoted. Such theory would take human-animal different types of relationships into account to decide what kind of ethical and political responsibilities humans have towards animals. It would be also based on the assumption that animals' sentience is the necessary and sufficient feature for assigning moral status. I start from the consideration that in the history of political philosophy, most theorists have excluded animals from the realm of justice. I then propose an examination of utilitarianism, capabilities approach, and relational-based theories of animal rights (in particular the works by Kymlicka and Donaldson, and Clare Palmer) and borrow essential elements from each of these approaches to build my theory. I claim that a political theory which attaches high importance to individual capabilities, as well as to the various types of relationships we have with animals, is the most appropriate to tackle the puzzle of …

Today, there is a growing number of buildings in a neighborhood and business parks that are utilizing renewable energy generation, to reduce their electric bill and carbon footprint. The most current way of implementing a renewable energy generation is to use solar panels or a windmill to generate power; then use a charge controller connected to a battery bank to store power. Once stored, the user can then access a clean source of power from these batteries instead of the main power grid. This type of power structure is utilizing a single module system in respect of one building. As the industry of renewable power generation continues to increase, we start to see a new way of implementing the infrastructure of the power system. Instead of having just individual buildings generating power, storing power, using power, and selling power there is a fifth step that can be added, sharing power. The idea of multiple buildings connected to each other to share power has been named a microgrid by the power community. With this ability to share power in a microgrid system, a catastrophic event which cause shutdowns of power production can be better managed. This paper then discusses the data …

Shape memory alloys (SMAs) operating as solid-state actuators pose economic and environmental benefits to the aerospace industry due to their lightweight, compact design, which provides potential for reducing fuel emissions and overall operating cost in aeronautical equipment. Despite wide applicability, the implementation of SMA technology into aerospace-related actuator applications is hindered by harsh environmental conditions, which necessitate extremely high or low transformation temperatures. The versatility of the NiTi-based SMA system shows potential for meeting these demanding material constraints, since transformation temperatures in NiTi can be significantly raised or lowered with ternary alloying elements and/or Ni:Ti ratio adjustments. In this thesis, the expansive transformation capabilities of the NiTi-based SMA system are demonstrated with a low and high-temperature NiTi-based SMA; each encompassing different stages of the SMA development process. First, exploratory work on the NiTiSn SMA system is presented. The viability of NiTiSn alloys as low-temperature SMAs (LTSMAs) was investigated over the course of five alloy heats. The site preference of Sn in near-equiatomic NiTi was examined along with the effects of solution annealing, Ni:Ti ratio adjustments, and precipitation strengthening on the thermomechanical properties of NiTiSn LTSMAs. Second, the thermomechanical processability of NiTiHf high-temperature SMA (HTSMA) wires is presented. The evolution of …

This thesis features a qualitative analysis of eight Korean media products — both fiction and nonfiction. For many years, South Korea (hereafter also called Korea) has been called the "world's plastic surgery capital" by many publications, such as Business Insider and The New Yorker. Although Business Insider considers the United States the "vainest country in the world," the numbers of cosmetic surgeries, percentage wise, per person in Korea still outnumber those in the United States, with 20 procedures per 1,000 persons. In this thesis, I argue by using the cultivation theory that Korean television, such as K-Dramas, talk shows and films, which celebrate transformations and feature makeovers and thus normalize cosmetic surgery, create a fantastic space for viewers where the viewers are compelled to act on a media-generated desire to undergo cosmetic surgery in the belief that doing so will also transform or better their lives in the same way it does for the characters in these Korean television productions.

Component failures can result in catastrophic behaviors in safety critical embedded systems, sometimes resulting in loss of life. Component failures can be treated as off nominal behaviors (ONBs) with respect to the components and sub systems involved in an embedded system. A lot of research is being carried out to tackle the problem of ONBs. These approaches are mainly focused on the states (i.e., desired and undesired states of a system at a given point of time to detect ONBs). In this paper, an approach is discussed to detect component failures and critical components of an embedded system. The approach is based on fault tree analysis (FTA), applied to the requirements specification of embedded systems at design time to find out the relationship between individual component failures and overall system failure. FTA helps in determining both qualitative and quantitative relationship between component failures and system failure. Analyzing the system at design time helps in detecting component failures and critical components and helps in devising strategies to mitigate component failures at design time and improve overall safety and reliability of a system.

One of the challenges of utilizing higher frequencies in the RF spectrum, for any number of applications, is the hardware constraints of analog-to-digital converters (ADCs). Since mid-20th century, we have accepted the Nyquist-Shannon Sampling Theorem in that we need to sample a signal at twice the max frequency component in order to reconstruct it. Compressive Sampling (CS) offers a possible solution of sampling sub-Nyquist and reconstructing using convex programming techniques. There has been significant advancements in CS research and development (more notably since 2004), but still nothing to the advantage of everyday use. Not for lack of theoretical use and mathematical proof, but because of no implementation work. There has been little work on hardware in finding the realistic constraints of a working CS system used for digital signal process (DSP). Any parameters used in a system is usually assumed based on stochastic models, but not optimized towards a specific application. This thesis aims to address a minimal viable platform to implement compressive sensing if applied to a wireless sensor network (WSN), as well as address certain parameters of CS theory to be modified depending on the application.

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.

The goal of this project completed for the Greater Northfield Sustainability Collaborative (GNSC) was to understand how Northfield, Minnesota citizens are experiencing climate change. Thirty individuals were interviewed to find out what they know about climate change, what actions they are taking, what they think the solutions are to the problems, and what barriers they have to more fully engaging with climate change issues. The interview results are intended to promote and advance the community's discussion on climate change via social learning and community engagement activities such as town hall forums and community surveys. These activities encourage citizens in the community to have direct input into the development of the community's climate action plan (CAP). Analysis of the interviews showed that the interviewees are witnessing climate change, that most are taking at least some action such as recycling or lowering thermostats, that they can name barriers to their own inaction, that they say communication about climate change remains confusing and is not widespread in Northfield, and that they are able to provide numerous suggestions for what the local and broader leadership should be doing. The analysis also showed wide individual variation within the group. Interviewees who were less knowledgeable about …

Positive and negative reinforcement contingencies have been compared in terms of preference, but the differential effects of positive and negative reinforcement on reaction time and accuracy with other variables controlled remain unclear. Fifteen undergraduate students participated in a sound discrimination task that involved random mixed-trial presentations of positive and negative reinforcement contingencies. The participants' goal was to correctly identify whether the tone was shorter or longer than 600 milliseconds. On positive reinforcement trials, the participants received feedback and money tallies only if they identified the sound length correctly, with each correct response in the positive reinforcement trials earning the participant 10 cents. On negative reinforcement trials, the participants received feedback and money tallies only if they identified the sound length incorrectly, with incorrect trials subtracting 10 cents from the participants' total money (which began at $4.00 to equalize the weights of the positive and negative reinforcement contingencies). Accuracy analyses showed a relatively curvilinear relationship between the number of errors for each participant and the binned duration of the sound stimulus, with no differences across the positive and negative reinforcement conditions. Results also indicated weak linear negative correlations at the single subject level between comparison stimulus duration and reaction time, with …

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.
