Description
Research on human grasp typically involves the grasp of objects designed for the study of fingertip forces. Instrumented objects for such studies have often been designed for the simulation of functional tasks, such as feeding oneself, or for rigidity such that the objects do not deform when grasped. The goal of this thesis was to design a collapsible, instrumented object to study grasp of breakable objects. Such an object would enable experiments on human grip responses to unexpected finger-object events as well as anticipatory mechanisms once object fragility has been observed. The collapsible object was designed to be modular to allow for properties such as friction and breaking force to be altered. The instrumented object could be used to study both human and artificial grasp.

Description
The generation of walking motion is one of the most vital functions of the human body because it allows us to be mobile in our environment. Unfortunately, numerous individuals suffer from gait impairment as a result of debilitating conditions like stroke, resulting in a serious loss of mobility. Our understanding of human gait is limited by the amount of research we conduct in relation to human walking mechanisms and their characteristics. In order to better understand these characteristics and the systems involved in the generation of human gait, it is necessary to increase the depth and range of research pertaining to walking motion. Specifically, there has been a lack of investigation into a particular area of human gait research that could potentially yield interesting conclusions about gait rehabilitation, which is the effect of surface stiffness on human gait. In order to investigate this idea, a number of studies have been conducted using experimental devices that focus on changing surface stiffness; however, these systems lack certain functionality that would be useful in an experimental scenario. To solve this problem and to investigate the effect of surface stiffness further, a system has been developed called the Variable Stiffness Treadmill system (VST). This treadmill system is a unique investigative tool that allows for the active control of surface stiffness. What is novel about this system is its ability to change the stiffness of the surface quickly, accurately, during the gait cycle, and throughout a large range of possible stiffness values. This type of functionality in an experimental system has never been implemented and constitutes a tremendous opportunity for valuable gait research in regard to the influence of surface stiffness. In this work, the design, development, and implementation of the Variable Stiffness Treadmill system is presented and discussed along with preliminary experimentation. The results from characterization testing demonstrate highly accurate stiffness control and excellent response characteristics for specific configurations. Initial indications from human experimental trials in relation to quantifiable effects from surface stiffness variation using the Variable Stiffness Treadmill system are encouraging.

Description
Scientists, lawyers, and bioethicists have pondered the impact of scientifically deterministic evidence on a judge or jury when deciding the sentence of a criminal. Though the impact may be one that relieves the amount of personal guilt on the part of the criminal, this evidence may also be the very reason that a judge or jury punishes more strongly, suggesting that this type of evidence may be a double-edged sword. 118 participants were shown three films of fictional sentencing hearings. All three films introduced scientifically deterministic evidence, and participants were asked to recommend a prison sentence. Each hearing portrayed a different criminal with different neurological conditions, a different crime, and a different extent of argumentation during closing arguments about the scientifically deterministic evidence. Though the argumentation from the prosecution and the defense did not affect sentencing, the interaction of type of crime and neurological condition did.

Noninvasive prenatal testing using cell-free fetal DNA (CffDNA) testing is a rapidly developing area in prenatal diagnosis. Fetal genetic testing can occur with a simple maternal blood sample, since CffDNA can be found in maternal plasma. Thus, no harm is caused to mother or fetus to obtain this genetic information, providing significant benefits for those users. How the test should be integrated in existing prenatal programs has yet to be seen. CffDNA testing is an exciting technology and has attracted attention from many stakeholders, yet the lack of regulation and guidance has left legal, ethical, and social questions unanswered. This paper outlines a number of those issues expressed in the present literature on the matter.

Description
Most daily living tasks consist of pairing a series of sequential movements, e.g., reaching to a cup, grabbing the cup, lifting and returning the cup to your mouth. The process by which we control and mediate the smooth progression of these tasks is not well understood. One method which we can use to further evaluate these motions is known as Startle Evoked Movements (SEM). SEM is an established technique to probe the motor learning and planning processes by detecting muscle activation of the sternocleidomastoid muscles of the neck prior to 120ms after a startling stimulus is presented. If activation of these muscles was detected following a stimulus in the 120ms window, the movement is classified as Startle+ whereas if no sternocleidomastoid activation is detected after a stimulus in the allotted time the movement is considered Startle-. For a movement to be considered SEM, the activation of movements for Startle+ trials must be faster than the activation of Startle- trials. The objective of this study was to evaluate the effect that expertise has on sequential movements as well as determining if startle can distinguish when the consolidation of actions, known as chunking, has occurred. We hypothesized that SEM could distinguish words that were solidified or chunked. Specifically, SEM would be present when expert typists were asked to type a common word but not during uncommon letter combinations. The results from this study indicated that the only word that was susceptible to SEM, where Startle+ trials were initiated faster than Startle-, was an uncommon task "HET" while the common words "AND" and "THE" were not. Additionally, the evaluation of the differences between each keystroke for common and uncommon words showed that Startle was unable to distinguish differences in motor chunking between Startle+ and Startle- trials. Explanations into why these results were observed could be related to hand dominance in expert typists. No proper research has been conducted to evaluate the susceptibility of the non-dominant hand's fingers to SEM, and the results of future studies into this as well as the results from this study can impact our understanding of sequential movements.

Description
The nonmedical use of prescription ADHD medications by American college students for the purpose of enhancing academic performance has been well-documented for more than a decade. A closer look at this trend through the lens of biomedicalization theory shows us that this behavior, which is often dismissed as a simple abuse of the system by deviant young people, is consistent with broader trends in post-modern medicine and health. The goal of this project was to describe the biomedicalization of studying by illustrating the historical, sociocultural, and politico-economic roots of nonmedical stimulant use by college students in the United States. An online survey was administered to students at ASU and responses from students studying in the College of Liberal Arts and Sciences (n=233) were analyzed. A 12.4% lifetime prevalence of illicit stimulant use was found among the sample population. Thematic analysis was performed on students' open-ended commentary and several themes related to the biomedicalization framework were uncovered including Necessity, Identity, Inextricability from academia, and Trust in the system. Through these themes it was found that many of the theorized transitions of biomedicalization were visible in the data set, confirming the idea that nonmedical stimulant use is embedded in the complex network of processes that represents post-modern medicine today.

Description
The knowledge of medical genetics is currently used with prenatal testing, and the advancements in the field of behavioral genetics may someday allow for its use with prenatal testing as well. The use of prenatal procedures for medical phenotypes has its own implications and should these techniques be used for behavioral phenotypes, such implications can also apply. The complexity of behavior in terms of the factors that may affect it, along with the way it is conceptualized and perceived, adds further implications for prenatal testing of it. In this thesis, I discuss the qualitative, quantitative, and historical facets of prenatal testing for medical and behavioral phenotypes and the undercurrent of eugenics. I do so by presenting an example of the medical phenotype (cystic fibrosis) as a case for envisioning the implications of medical phenotypes before delving into examples of behavioral phenotypes (aggression, impulsivity, extraversion, and neuroticism) in order to explore the implications shared with those for medical phenotypes as well as those unique to it. These implications then set the foundation for a discussion of eugenics, and the considerations for how behavioral genetics with prenatal testing may give way to a modern form of it.

Description
Electromyography (EMG) and Electroencephalography (EEG) are techniques used to detect electrical activity produced by the human body. EMG detects electrical activity in the skeletal muscles, while EEG detects electrical activity from the scalp. The purpose of this study is to capture different types of EMG and EEG signals and to determine if the signals can be distinguished between each other and processed into output signals to trigger events in prosthetics. Results from the study suggest that the PSD estimates can be used to compare signals that have significant differences such as the wrist, scalp, and fingers, but it cannot fully distinguish between signals that are closely related, such as two different fingers. The signals that were identified were able to be translated into the physical output simulated on the Arduino circuit.

Description
Vaccine opposition is a growing problem in developed countries where dropping vaccination rates threaten general public health by laying the foundation for resurgence and reemergence of previously eradicated infectious diseases. This thesis argues that the current movement is only the most recent incarnation of opposition that has co-evolved with vaccine practices for the duration of their mutual histories. Part one provides a historical context for the current movement using the example of the development and deployment of the smallpox vaccine as a representative timeline of vaccine acceptance and opposition. Part two describes the current movement in the United States and the United Kingdom, interprets the reasons for the conclusions drawn by vaccine-concerned parents, and provides a framework for public health officials to approach the issues.
