Description
Partial differential equation (PDE) models are widely used for modeling processes in the physical sciences, economics, and sociology, but are otherwise new to the realm of social media. They allow researchers to construct a single spatiotemporal mathematical model to predict, in the case of this study, the level of information saturation at particular points in space at specific times. Utilizing data from the popular social network Twitter, this study presents a preliminary work looking into the effects of aggregating spatial data on such a PDE model. In other literature, the source of analytical and statistical bias that results from arbitrary spatial aggregation is known as the modifiable areal unit problem (MAUP). We use a previously-studied dataset from the 2011 Egyptian revolution for simulation, and group data points using several distance metrics based on geographical location and geo-cultural similarity. This paper will attempt to show that a PDE model, necessarily dependent upon aggregating data, is subject to significant bias when said data are arbitrarily organized and grouped for simulation. We look primarily into the zoning problem, which amounts to maintaining a fixed number of regions located in different areas across the globe, but make note of the scale problem, an inherent issue in PDE modeling that results from aggregating data points into increasingly larger regions. From looking at specific values from each simulation, this study shows that such a model is not free from the MAUP and that consideration of how data are aggregated needs to be made for future studies. In addition, it also suggests that geo-political and geo-cultural spatial metrics generate better diffusive patterns for tweet propagation than do simple geographical proximity metrics.

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
It seems that we are incessantly scolded about the importance of the American political process and its virtue of practicality in contemporary society. Whether through the accumulation of the so-called facts about the issues that inform the veneration of the contest between candidates, the stern and noble duty of becoming an activist performing dreary tasks, or the religious fervor surrounding the sacred obligation of voting, we are assured and reassured that our system is sound and that we must only confront problems of implementation rather than structural ones. From here, the narrative goes that if we subscribe to the doctrine of exclusively employing the efficient, strictly rational, and the immediately realistic, we will almost assuredly succeed in persuading others toward producing the resolutions required to solve our shared challenges. Admittedly, these ideas serve a role in addressing the issues we face. However, when unaided by sophisticated and nuanced notions and applications of the fantastic, the beautiful, the ideal, the possible, the playful, the useless, in a word, dreaming, we foreclose the possibility of building a future that can qualitatively improve society and more meaningfully elevate our being-with-one-another in the world. Therefore, this work aims to validate the aforementioned claim by engaging in a critical, political, and hermeneutic exploration of what it means to dream against the backdrop of present-day American politics. It will honestly seek to analyze the prevailing notions of contemporary western thought and action to work on the way toward a new, yet latent, way of understanding. This understanding would fundamentally revolutionize the task of civilization as being grounded upon the appropriate channeling of our desires and dissatisfactions toward actualizing the projections of our imagination. Simply put, this project seeks to repudiate the mandate of work as toil and order as oppression to clear the way for envisioning a more suitable alternative.

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
This thesis aims to explain how a child can deal with loss through a children's book that I have written and illustrated. The goal is to have a child, as young as the age of seven, be able to pick up the book and come away with an initial understanding of how grief affects people. There are references to other works of literature similarly dealing with the above topic. The different stages of grief are examined, as well as the ways in which grief can be handled. Facial expressions and body language are crucial to understanding others' pain and grief, so this thesis delves into how to translate different expressions and actions, and how artwork and illustrations can portray these same ideas. The story from the book is interwoven throughout the thesis, so as to show my reasoning for each section of the text. Finally, there is a full analysis of the text as well as the illustrations that explains why the text is fitting for each section of the story.

Description
This thesis argues that our current attitudes toward meat consumption should be questioned for multiple reasons: because eating meat is cruel to the animals being eaten, it is detrimental to the environment, it is not at all necessary for a balanced diet, and lastly because the amount of faux meat options are endless. To begin the thesis describes the types of meat filled food that surrounds all of us, as Americans, in our everyday lives. It then meditates on the history of these other non-meat choices, in order to show how important faux meat has been throughout time for various cultures and religions. The work then continues from the past to the present, and profiles the growing availability and abundance of faux meat products in North American culture. In doing this it presents the current vegetarian meat options available to the average American consumer. In hopes of convince consumers that choosing ethically doesn't have to mean choosing blandly, it presents reviews of the taste, texture, and physical appearance of the more popular faux meat products on the market today. After which it turns to the future and commends technological and scientific endeavors in the search for a new cruelty free meat source through in-vitro meat research. And finally this thesis explains the disastrous environmental impact of our current meat filled diets. It concludes that the strong westerner tradition of eating meat is not necessarily the right way to eat. By purchasing and eating meat the consumer is voting, with their dollar, for animal abuse and environmental destruction. The consequences of eating meat are atrocious enough that if people are given a more ethical, delicious, and cheap meat-alternative they will chose it.

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
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.

Delegation is a very important skill for a manager to have in any organization and is of the utmost importance when it comes to tasks being executed. Often times, delegation can be seen as something that managers dread because they do not want to give up their power and they feel that they can do it better. The notion of delegation can be something that is influenced by a variety of factors. For one, gender can be a driving force in how managers talk to their employees. In this project I will be exploring sections of Genderlect theory in how men and women's communication styles are received differently. Critical theory of communication approaches will also be explored. Also, the way in which delegation is used is what needs the most attention. That is where relational and nonverbal communication also come into play. All in all, the way in which society is constructed, delegation is a skill that needs to be mastered because the job needs to get done.
