Representing And Inferring Mental Workload Via Defeasible Reasoning: A Comparison With The Nasa Task Load Index And The Workload Profile, Lucas Middeldorf Rizzo, Luca Longo

Conference papers

The NASA Task Load Index (NASA − TLX) and the Workload Profile (WP) are likely the most employed instruments for subjective mental workload (MWL) measurement. Numerous areas have made use of these methods for assessing human performance and thusly improving the design of systems and tasks. Unfortunately, MWL is still a vague concept, with different definitions and no universal measure. This research investigates the use of defeasible reasoning to represent and assess MWL. Reasoning is defeasible when a conclusion, supported by a set of premises, can be retracted in the light of new information. In this empirical study, this type …

Phytoplankton Plastid Proteomics: Cracking Open Diatoms To Understand Plastid Biochemistry Under Iron Limitation, Skyler J. Nunn, Phoebe Dreux Chappell, Kristofer Gomes, Anasthasia Bonderenko, Bethany D. Jenkins, Brook L. Nunn

OES Faculty Publications

Diatoms, such as Thalassiosira pseudonana, are important oceanic primary producers, as they sequester carbon dioxide (CO₂) out of the atmosphere, die, and precipitate to the ocean floor. In many areas of the world’s oceans, phytoplankton, such as diatoms, are limited in growth by the availability of iron (Fe). Fe is an essential nutrient for phytoplankton, as it is central in the electron transport chain component of photosynthesis. Through this study, we examined if Fe-limitation makes a significant difference in the proteins expressed within the chloroplast, the power source for diatoms. Here, we utilized a new plastid isolation technique specific …

Producing A College Graduate Using Retention, Progression, And Graduation (Rpg) Initiatives: A University Systems’ Approach, Deborah N. Kittrell-Mikell

College of Graduate Studies: Theses & Dissertations

ABSTRACT

Complete College Georgia (CCG) is an initiative that has the University System of Georgia institutions strategizing ways to develop plans that will increase the number of college graduates by the year 2020. Governor Nathan Deal has indicated that graduation rates need to increase from 42% to 60% within the next 7 years. With the anticipation of approximately 20% more students graduating to meet the 250,000 target, a closer look is needed at how an additional 50,000 graduates can be produced to make this goal a reality. To fulfill this goal, there needs to be an increase of approximately 7,143 …

Puzzled Representations: Popular Media And How Educators Come To Know Autism, Vanessa N. Keener

College of Graduate Studies: Theses & Dissertations

People learn about the world through popular culture. Popular culture media representations of autism can be found in TV, film, literature, Internet media, advertisements, and more. This study employed a quantitative correlational design to survey 273 Georgia educators regarding their perceptions of autism, including knowledge about autism, best practices for teaching students labeled as having autism, perceived positivity and accuracy of popular media representations of autism, as well as participant identification with popular media representations of autism and personal characteristics (i.e., age, sex, level of education, type of degree, years of teaching experience, professional and personal experiences). Six major findings …

Variation In Larval Behavior Across The Ecologically Distinct Host Populations Of The Cactophilic Drosophila Mojavensis, Joshua Coleman

Theses

Ecological host shifts likely have a major impact on the evolution of species. The host shift can result in an organism being faced with significant chemical, nutritional, volumetric, and other challenges, which may lead to adaptation. Host shifts can lead to speciation by prezygotic isolation, and even reinforcement through postzygotic isolation. This study looks at behavioral differences in terms of larval activity in populations of Drosophila mojavensis which have experienced host shifts. The mean speed of the four populations of D. mojavensis larvae were measured, and considered in the ecological context. A single nucleotide polymorphism (SNP) DNA library was prepared …

Kinetic Analysis Of The Hypergolic Reactivity Of Dimethylpiperazines With Red Fuming Nitric Acid, Kenneth Haines

Theses

This research investigated the hypergolic reaction that occurs between dimethylpiperazines with red fuming nitric acid. An advanced laser diagnostic system was designed previously to measure chemical delay times. This equipment was utilized to study the effects of temperature, fuel to oxidizer ratio, the presence of dinitrogen tetroxide in the oxidizer and the presence of methanol in the fuel. A comparison was made with dimethylpiperazine isomers and derivatives of hydrazine previously studied.

Full Circle: The New Deal And The Great Recession, Donald Lewis Roberts

Honors College Theses

In this paper I will show how the mindset of liberalism has evolved since the Great Depression. It merged with progressive movement of the late 19^th and early 20^th centuries to become a politically left ideology that intertwined with power hungry politicians who perverted liberalism and used sudden economic and social phenomena to engineer a new type of American government. One that has constantly expanded, reaching and entrenching itself further and further into the lives of Americans, starting with President Franklin Roosevelt. Roosevelt’s work would be expanded in the name of progress and equality by several of his …

Individual Domestic Terrorism: An Analysis Of The Motivations And Radicalization Of Terrorism In The United States, Tony Hudson Jr.

Honors College Theses

Individual terrorist events have increased in the United States. What are the motivations behind these attacks and what led these individuals to participate in this form of political violence? In this paper, I provide a case study analysis of four domestic terrorist attacks in the United States that have been executed by individual perpetrators. I combine rational choice, sociological, and psychological theories in order to show a similar path of radicalization taken by each of the terrorists involved in these attacks. I build upon previous research on the importance of studying terrorism from an individual- analysis perspective.

Youth And Social Media: Power To Empower?, Sujith Kumar Prankumar

Research Collection School of Social Sciences

Much has been written on social media and how it has positively revolutionised communication and information transmission. The infl uence of social media is indubitable—it reaches anyone with an Internet connection, no matter their geographic location or socioeconomic status. This means information that was previously out of reach for isolated and less well-off communities is now accessible by more people than ever before. For example, University College London’s “Why We Post” social media anthropology project—conducted by nine researchers in nine different communities over 15 months—found that communities that have traditionally received comparatively lower levels of schooling now have access to …

Remembering 1965: Indonesian Cinema And The 'Battle For History', Espena Darlene Machell

Research Collection School of Social Sciences

Using four films to probe the transformations in Indonesia’s historical memory, this paper examines how the Indonesian society remembers, interrogates, and comes to terms with one of their nation’s most traumatic episodes: the widespread communist purge that followed the failed coup on 30 September 1965. It also demonstrates how they reflect various perspectives on the 1965 killings that are—to an extent—part of the “Battle of History” (van Klinken 2001) in postSuharto Indonesia, wherein different historiographic traditions introduce new actors, reveal the nuances, and challenge longstanding dominant understandings of 1965.

Navigating The (Im)Perfect Performances Of Queer Iranian-American Identity, Shadee Abdi

Electronic Theses and Dissertations

Within the social sciences and humanities, failure to adequately account for the intersectional ways people of color navigate their multiple identities within contesting cultural systems, creates an unfinished portrait of queer identity. For queer people of color, negotiating queer identity is always in relation to their nationality, race-ethnicity, class, gender, religion, and family. While many queer of color stories share similar obligatory cultural norms, the legal ramifications that impact the lives of queer Iranians and their families, both within Iran and abroad, challenge many queer of color expectations. Due to stringent cultural and legal influences, Iranian social discourse heavily impacts …

3d Bioprinting Hydrogel For Tissue Engineering An Ascending Aortic Scaffold, Benjamin Stewart

Electronic Theses and Dissertations

The gold standard in 2016 for thoracic aortic grafts is Dacron^®, polyethylene terephthalate, due to the durability over time, the low immune response elicited and the propensity for endothelialization of the graft lumen over time. These synthetic grafts provide reliable materials that show remarkable long term patency. Despite the acceptable performance of Dacron^® grafts, it is noted that autographs still outperform other types of vascular grafts when available due to recognition of the host's cells and adaptive mechanical properties of a living graft. 3-D bioprinting patient-specific scaffolds for tissue engineering (TE) brings the benefits of non-degrading synthetic …

Science Possible Selves And The Desire To Be A Scientist: Mindsets, Gender Bias, And Confidence During Early Adolescence, Patricia Wonch Hill, Julia Mcquillan, Eli Talbert, Amy N. Spiegel, G. Robin Gauthier, Judy Diamond

Department of Sociology: Faculty Publications

In the United States, gender gaps in science interest widen during the middle school years. Recent research on adults shows that gender gaps in some academic fields are associated with mindsets about ability and gender-science biases. In a sample of 529 students in a U.S. middle school, we assess how explicit boy-science bias, science confidence, science possible self (belief in being able to become a scientist), and desire to be a scientist vary by gender. Guided by theories and prior research, we use a series of multivariate logistic regression models to examine the relationships between mindsets about ability and these …

Contextualizing The Relationship Between Culture And Puerto Rican Health: Towards A Place-Based Framework Of Minority Health Disparities, Giovani Burgos, Fernando I. Rivera, Marc A. Garcia

Department of Sociology: Faculty Publications

In both the culture of poverty literature and the acculturation literature, Puerto Ricans are portrayed in negative terms. The culture of poverty framework attributes Puerto Rican poverty to the mental, behavioral, and moral pathology of Puerto Rican individuals and to Puerto Rican culture. Similarly, outdated acculturation frameworks also trace the poor health of immigrants and racialized minorities, such as Puerto Ricans, to equivalent perceived deficiencies. In this paper, we argue that both the culture of poverty and acculturation frameworks are two pillars of the White Racial Frame (Feagin 2009) that sustains racial inequality in the United States. To build our …

Stress Exposure And Physical, Mental, And Behavioral Health Among American Indian Adults With Type 2 Diabetes, Melissa L. Walls, Kelley J. Sittner Hartshorn, Benjamin D. Aronson, Angie K. Forsberg, Les B. Whitbeck, Mustafa Al'absi

Department of Sociology: Faculty Publications

American Indian (AI) communities experience disproportionate exposure to stressors and health inequities including type 2 diabetes. Yet, we know little about the role of psychosocial stressors for AI diabetes-related health outcomes. We investigated associations between a range of stressors and psychological, behavioral, and physical health for AIs with diabetes. This community-based participatory research with 5 AI tribes includes 192 AI adult type 2 diabetes patients recruited from clinical records at tribal clinics. Data are from computer-assisted interviews and medical charts. We found consistent bivariate relationships between chronic to discrete stressors and mental and behavioral health outcomes; several remained even after …

The Republicanization Of Evangelical Protestants In The United States: An Examination Of The Sources Of Political Realignment, Philip Schwadel

Department of Sociology: Faculty Publications

Although the association between evangelical Protestant and Republican affiliations is now a fundamental aspect of American politics, this was not the case as recently as the early 1980s. Following work on secular political realignment and the issue evolution model of partisan change, I use four decades of repeated cross-sectional survey data to examine the dynamic correlates of evangelical Protestant and Republican affiliations, and how these factors promote changes in partisanship. Results show that evangelical Protestants have become relatively more likely to attend religious services and to oppose homosexuality, abortion, and welfare spending. Period-specific mediation models show that opposition to abortion, …

Book Review: The New Confessions Of An Economic Hit Man By John Perkins, Natalie Disque

Journal of Sustainable Social Impact

Author John Perkins writes a bold, yet compelling, account of his personal experiences as an economic hit man (EHM), involving manipulating data and foreign government officials, deception, lies, sex, assassinations, and attempted murder. His true story recounted in the book The New Confessions of an Economic Hit Man is an eye-opener for those who are unaware of the underpinnings of the government’s ability to bully other countries into large debt to benefit American multinational corporations and secure our place as the sole superpower.

Happiness In Communities: How Neighborhoods, Cities And States Use Subjective Well-Being Metrics, Laura Musikanski, Carl Polley, Scott Cloutier, Erica Berejnoi, Julia Colbert

Journal of Sustainable Social Impact

This essay, the fourth and last of a series published by the Journal of Social Change, is intended as a tool for community organizers, local policy makers, researchers, students and others to incorporate subjective well-being indicators into their measurements and management of happiness and well-being in their communities, for policy purposes, for research and for other purposes. It provides case studies of community-based efforts in five different regions (São Paulo, Brazil; Bristol, United Kingdom; Melbourne, Australia; Creston, British Columbia, Canada; and Vermont, United States) that either developed their own subjective well-being index or used the Happiness Alliance’s survey instrument …

Walden University’s social change approach is an essential part of its vision and is transmitted through the academic work and knowledge of its graduates, who are trained to find solutions to critical societal challenges in pursuit of advancing the greater global good. Schuerkens’ Social Changes in a Global World can serve as a compendium for the Walden family and others interested in this topic. The author examines how social transformations and changes are connected to issues of power and political influence; how transformations and changes have been influenced by concepts of modernity, progress, and rationalization; how transformations and changes differ …

The Relationship Between Social Change Involvement And Education, Michelle S. Brown, Beate Baltes

Journal of Sustainable Social Impact

Positive social change is part of Walden University’s mission. As such, the institution sponsored the Social Change Impact Report, which includes data from three online surveys that investigated participants’ experiences with social change because factors related to involvement in social action to improve the lives of individuals and communities are not fully known. Data were collected from the Social Change Impact Report to examine the relationship between the level of education an individual has achieved and how they rate the importance of and the involvement in positive social change activities. Results of chi square and analysis of variance indicated …

The Imperative Of The Corporation And Socially Conscious Leadership, Ekpen Owie

Journal of Sustainable Social Impact

The word corporation and the activities of corporations around the world are no longer a mystery to many. Laws create corporations as persons, independent of the owners. There have been widespread debates about the propensity of corporations to harm others while trying to maximize profits, as well as the arguments that corporations should not delve into corporate social responsibility unless it directly enhances the bottom line. Nevertheless, individuals run corporations. I posit from a synthesis of literature that such individuals, if socially conscious, could institute the right governance mechanisms for driving corporate social responsibility and balancing multistakeholder interests.

On Being Disrupted: Youth Work And Black Lives Matter, Angela Marie Bonfiglio
