****Project Disclaimer: Unfortunately due to the COVID-19 outbreak during Spring 2020, ASU shut down in-person classes and campus facilities as means to prevent the spread of the virus. This meant though that a polished final podcast recording was unable to be made. Instead, a first-run, practice podcast recording that was recorded before the shut down is uploaded in its stead as a reference as to how the final was intended to sound and be produced. ****

Cellular hypertrophy is an anaerobically-based, adaptive process that mammalian skeletal muscle undergoes in response to damage resulting from unaccustomed force generation by the muscle. Hypertrophy allows for the muscle tissue to recover from the immediate injury and also to be rebuilt more capable of withstanding producing the same amount of force without injury, should it happen again. This means the end result of an adapted muscle is an overall more efficient tissue. The ability to regenerate after damage to the structure and function of the muscle tissue is a highly orchestrated event involving multiple steps and key events to occur. Most briefly, a mechanical load is attempted to be lifted but due to demanding a high amount of contractile force to lift, it causes microdamage to the structural and contractile elements of muscle fiber’s sarcomeres. In addition to an inflammatory response, satellite cells, as a part of a myogenic response, are activated to invade the fiber and then permanently reside inside to produce new proteins that will replace the damaged and necrotized proteins. This addition of cellular content, repeated over multiple times, results in the increased diameter of the fibers and manifests in the visual appearance of skeletal muscle hypertrophy. These steps have been listed off devoid of the contexts in which it takes for these to occur and will be addressed within this thesis.

Throughout history humans have had to adapt to changing conditions in order to survive. Food shortages are one of the major pressures that have shaped past populations. Because of this, the human body has many physiological adaptations that allow it to go extended periods of time consuming little to no food. These adaptations also allow the body to recover quickly once food becomes available. They include changes in metabolism that allow different fuel sources to be used for energy, the storing of excess energy absorbed from food in the forms of glycogen and fat to be used in between meals, and a reduction in the basal metabolic rate in response to starvation, as well as physiological changes in the small intestines. Even in places where starvation is not a concern today, these adaptations are still important as they also have an effect on weight gain and dieting in addition to promoting survival when the body is in a starved state.

Disclaimer: The initial goal of this project was to present this information as a podcast episode as a part of a series aimed at teaching the general public about human physiological adaptations. Due to the circumstances with COVID-19 we were unable to meet to make a final recording of the podcast episode. A recording of a practice session recorded earlier in the year has been uploaded instead and is therefore only a rough draft.

Oedipus Wrought: Morality and Fear in Oedipus Rex Across Media

This project analyzes the use of fear appeals in transmitting a moral of self-realization in the drama Oedipus Rex and its adaptations into painting and film. It draws upon earlier work in media ecology, adaptation, and studies of emotions in media. It proposes that what distinguishes media from one another is the unique way that each medium stimulates the reader to draw from their own experiences with life and literature. Alternatively, what unites media is the cross platform assimilation of author and reader reality. More specifically, it asserts that print stimulates the reader via immersion, that painting achieves this same effect by acting as a proxy for the reader to embody the image before them, and that film stimulates the viewer as a result of emotive focus. Collectively, it concludes that when it comes to Oedipus and its many forms, the plays utilize fear to communicate the moral through both surface and dense texts, while painting adaptations focus on dense texts, and the filmic adaptations emphasize their surface equivalent. The project’s significance rests in its challenge to Marshal McLuhan’s technological determinism. On exposing the effects that a reader’s varied mindset can have on a medium’s ability to communicate its message, the project highlights that the relationship between humankind and media is not so deterministic and is more complex than McLuhan would have us believe.

Adaptation Podcast: The Physiological Adaptation to Isolation

Description

The purpose of this project was to discuss the physiological effects of isolation on the human body and how the body adapts. Through reviewing stories and studies of social and perceptual isolation, the adaptations of the human mind are detailed.

The purpose of this project was to discuss the physiological effects of isolation on the human body and how the body adapts. Through reviewing stories and studies of social and perceptual isolation, the adaptations of the human mind are detailed. This project explores the experiences of prisoners, sensory deprivation tanks, cave explorations, as well as studies involving monkeys and carpenter ants. The adaptations witnessed include hallucinations, increased mortality, anxiety, agitation, altered sense of time, delayed response, and lowered blood pressure. Knowing the factors surrounding the isolation experience is crucial to understand the presenting adaptation methods. These factors include duration, voluntary or involuntary participation, mental strength, and the restriction level of the isolation.

DISCLAIMER: Due to the unexpected COVID-19 pandemic, the attached podcast is a draft recording in lieu of the final recording

In the past, researchers have studied the elements of speech and how they work together in the human brain. Auditory feedback, an important aid in speech production, provides information to speakers and allows them to gain an understanding if the prediction of their speech matches their production. The speech motor system uses auditory goals to determine errors in its auditory output during vowel production. We learn from discrepancies between our prediction and auditory feedback. In this study, we examined error assessment processes by systematically manipulating the correspondence between speech motor outputs and their auditory consequences while producing speech. We conducted a study (n = 14 adults) in which participants’ auditory feedback was perturbed to test their learning rate in two conditions. During the trials, participants repeated CVC words and were instructed to prolong the vowel each time. The adaptation trials were used to examine the reliance of auditory feedback and speech prediction by systematically changing the weight of auditory feedback. Participants heard their perturbed feedback through insert earphones in real time. Each speaker’s auditory feedback was perturbed according to task-relevant and task-irrelevant errors. Then, these perturbations were presented to subjects gradually and suddenly in the study. We found that adaptation was less extensive with task-irrelevant errors, adaptation did not saturate significantly in the sudden condition, and adaptation, which was expected to be extensive and faster in the task-relevant condition, was closer to the rate of adaptation in the task-irrelevant perturbation. Though adjustments are necessary, we found an efficient way for speakers to rely on auditory feedback more than their prediction. Furthermore, this research opens the door to future investigations in adaptation in speech and presents implications for clinical purposes (e.g. speech therapy).

Spatial Climate Justice and Green Infrastructure Assessment: A Case Study for the Huron River Watershed, Michigan, USA

Green infrastructure serves as a critical no-regret strategy to address climate change mitigation and adaptation in climate action plans. Climate justice refers to the distribution of climate change-induced environmental hazards (e.g., increased frequency and intensity of floods) among socially vulnerable groups. Yet no index has addressed both climate justice and green infrastructure planning jointly in the USA. This paper proposes a spatial climate justice and green infrastructure assessment framework to understand social-ecological vulnerability under the impacts of climate change. The Climate Justice Index ranks places based on their exposure to climate change-induced flooding, and water contamination aggravated by floods, through hydrological modelling, GIS spatial analysis and statistical methodologies. The Green Infrastructure Index ranks access to biophysical adaptive capacity for climate change. A case study for the Huron River watershed in Michigan, USA, illustrates that climate justice hotspots are concentrated in large cities; yet these communities have the least access to green infrastructure. This study demonstrates the value of using GIS to assess the spatial distribution of climate justice in green infrastructure planning and thereby to prioritize infrastructure investment while addressing equity in climate change adaptation.

Testbed Implementation of the Meta-MAC Protocol

The meta-MAC protocol is a systematic and automatic method to dynamically combine any set of existing Medium Access Control (MAC) protocols into a single higher level MAC protocol. The meta-MAC concept was proposed more than a decade ago, but until now has not been implemented in a testbed environment due to a lack of suitable hardware. This thesis presents a proof-of-concept implementation of the meta-MAC protocol by utilizing a programmable radio platform, the Wireless MAC Processor (WMP), in combination with a host-level software module. The implementation of this host module, and the requirements and challenges faced therein, is the primary subject of this thesis. This implementation can combine, with certain constraints, a set of protocols each represented as an extended finite state machine for easy programmability. To illustrate the combination principle, protocols of the same type but with varying parameters are combined in a testbed environment, in what is termed parameter optimization. Specifically, a set of TDMA protocols with differing slot assignments are experimentally combined. This experiment demonstrates that the meta-MAC implementation rapidly converges to non-conflicting TDMA slot assignments for the nodes, with similar results to those in simulation. This both validates that the presented implementation properly implements the meta-MAC protocol, and verifies that the meta-MAC protocol can be as effective on real wireless hardware as it is in simulation.

Cryospheric Hazards and Risk Perceptions in the Mt. Everest Region, Nepal

Description

Multiple studies have reported potential risks posed by a rapid expansion of glacial lakes in the Mt. Everest region of Nepal. People’s perception of such cryospheric hazards can influence their actions, beliefs, and responses to those hazards and associated risks.

Multiple studies have reported potential risks posed by a rapid expansion of glacial lakes in the Mt. Everest region of Nepal. People’s perception of such cryospheric hazards can influence their actions, beliefs, and responses to those hazards and associated risks. This paper analyzes local people’s perceptions of cryospheric hazards and risks using a social survey dataset of 138 households in the Khumbu and Pharak areas of the Mt. Everest region of Nepal. A statistical logit model of categorical household data showed a significant positive correlation with the perceptions of cryospheric risks to their livelihood sources, mainly tourism. Local people’s GLOF risk perceptions are also influenced by their proximity to rapidly expanding glacial lakes and potential flood zones located in Dudhkoshi River basin. The emergency remediation work implemented in the Imja glacial lake by the Government of Nepal in 2016 has served as a cognitive fix, especially in the low lying settlements in Pharak. Uncertainties of cryosphere that exist in the region can be attributed to a disconnect between how scientific knowledge on GLOFs risks is communicated to the local communities and how government policies on climate change adaptation and mitigation have been limited only to awareness campaigns and emergency remediation works. A sustainable partnership of scientists, policymakers, and local communities is urgently needed to build a science-driven, community-based initiative that focuses not just in addressing a single GLOF threat (e.g., Imja) but develops on a comprehensive cryospheric risk management plan and considers opportunities and challenges of tourism in the local climate adaptation policies.
