Role Assigning And Taking In Cloud Computing, Shafaq Naheed Khan, Mathew Nicho, Haifa Takruri, Zakaria Maamar, Faouzi Kamoun

All Works

© 2019 - IOS Press and the authors. All rights reserved. The widespread use of cloud computing (CC) has brought to the forefront information technology (IT) governance issues, rendering the lack of expertise in handling CC-based IT controls a major challenge for business enterprises and other societal organizations. In the cloud-computing context, this study identifies and ranks the determinants of role assigning and taking by IT people. The study's integrative research links CC and IT governance to humane arrangements, as it validates and ranks role assigning and taking components through in-depth interviews with twelve IT decision-makers and forty-four Information Systems …

Violence Is As American As Cherry Pie: Mass Incarceration And Juvenile Violence, Stephen C. Stanko, Gordon A. Crews

Criminal Justice Faculty Publications

The purpose of this chapter is to offer “food for thought” regarding an under researched area of juvenile violence causation: the possible connection between steadily increasing incarceration rates and steadily increasing incidents of school violence. Unfortunately, the negative, and sometimes violent, traits individuals develop while incarcerated are often brought out into their lives in society and personal lives, which often involve the raising of children. Research has documented the impacts that being incarcerated can have upon an individual. There is growing research supporting that these newly developed traits and behaviors can easily be imbedded in the children in which they …

When A Little Goes A Long Way: Expanding Home Care Services To Adults With Disabilities, Serena Hasworth, Jaclyn Winfree, Ozcan Tunalilar, Diana L. White

Institute on Aging Publications

Policy makers are increasingly interested in reducing public spending while maintaining quality of life. Since 1975, Oregon Project Independence (OPI) has supported community-based adults aged 60 and older to avoid or delay the need for residential long-term care services by increasing access to personal and home care services. The program also aims to prevent the need for Medicaid by optimizing personal resources and natural supports. In 2014, the OPI Expansion (OPI-E) pilot project began to serve adults aged 18-59 with disabilities in seven of Oregon’s seventeen Area Agencies on Aging (AAAs). This poster describes the evaluation of the expansion using …

Aeg-1 Knockout Sensitizes Hepatocellular Carcinoma (Hcc) Cells To Ionizing Radiation, Maheen Khan

Theses and Dissertations

Liver cancer is the fourth leading cause of cancer-associated deaths globally, and among primary liver cancers, hepatocellular carcinoma (HCC) encompasses 75-85% of all cases. HCC is a highly lethal disease due to limited treatment options – only a small subset of patients qualify for surgical resection or transplantation; the remaining patients often display resistance to radiation therapy or chemotherapy. Overexpression of the oncogene astrocyte elevated gene-1 (AEG-1) is associated with poorer survival and increased tumor recurrence in HCC, and numerous studies show its role in initiation of hepatocarcinogenesis. A prior study also demonstrated AEG-1 expression inhibits senescence by diminishing the …

Regenerative Potential Of Mesenchymal Stem Cell Derived Exosomes, Andrew P. Wong

Theses and Dissertations

Bone defects are a pervasive complication arising from many clinical conditions, both mechanical and pathological. Current treatments for large bony defects focus on applying bone grafts or synthetic materials to the defect area. Cell-based—and especially stem-cell—therapies have advanced greatly thanks to increasing attention focused on their ability to generate new tissues in situ with biomechanical properties approaching that of native tissue, but they suffer from their own shortcomings as well. Exosomes have been shown to play critical roles in cell-signaling and tissue regeneration and are therefore potentially ideal therapeutic vehicles for treating bone defects. Exosomes are small microvesicles counted amongst …

Bantaba: Designing The Sacred Circle, Tashiara Scott

Theses and Dissertations

MOTIVATION In Richmond, there are 1.21 times as many African Americans as any other ethnic group. Yet 63.4% of African Americans live in poverty (Richmond, VA). African Americans face greater exposure to stress due to low socioeconomic status and poverty. In these communities, “discrimination and deprivation undermine individuals’ ability to accumulate the social and material resources to mitigate the effects of stress” (Brondolo, 2018). In this city’s African American community, where stress levels are high and consequential health concerns are prevalent, dance can be a remedy for managing stress and improving health (Hanna, 2006).

Light In Community: A Study In The Adaptive Reuse Of Sacred Space, Abigail Barras

Theses and Dissertations

ABSTRACT

MOTIVATION
American life is increasingly fragmented, leading to a sense of restlessness and disconnection. Much of that fragmentation can be traced to our pattern of architectural and sociological development, namely, the rise of the automobile suburbs in the 1950s and 60s and the abandonment of densely populated, human- scaled environments like that of the small town or city center (Oldenberg, 1999).

PROBLEM
Large numbers of architecturally significant buildings have fallen into disrepair over the years following the “white flight” of the 1960s and 70s, during which significant segments of investment dollars left city centers and followed to the suburbs …

In A Building, A Stairwell, A Room Speaks, Tsz Wai Wallis Cheung

Theses and Dissertations

Working toward a personal definition of womanhood while progressing with my research in feminist discourse, I frame biographical events alongside the intricate use of language surrounding feminist theory. Experimenting with material specificities that speak to my personal narratives and cultural significance, my work seeks to address the interlacing operations of subjectivity expanding on the intersection of class, gender and race.

The What If Collection, Aisha J. Daniels

Theses and Dissertations

The What If Collection is a visual narrative that confronts white supremacy, the social, economic, and political ideology used to subjugate black civilization via colonial rule and enslavement in history and via structural racism today. Many white people have been socialized into a racial illiteracy that fosters white supremacy. This racial illiteracy fails to realize and understand the destructive effects of Western dominance on the rest of the world, particularly on past and present Africa and her diaspora. In response, utilizing discursive design, the collection constructs a counter-story that depicts a shift in the power structure in which the white …

Weaponization Of Space: Subverting The Architecture Of Occupation, Majdulin Nasrallah

Theses and Dissertations

Israel’s illegal occupation of Palestine and oppression of the Palestinian people has manifested itself in countless ways. The built environment, fueled by spatial theory, has been transformed into an instrument of war that serves a military agenda. In this context, the physical environment is not simply the arena of conflict, but a weapon wielded by occupying forces. This research investigates spatial control through seemingly mundane architecture and military practices, which are deployed deliberately to strangulate Palestinian livelihood and prosperity. Derived from Deleuze and Guittari’s delineation of smooth and striated space, with an emphasis on walls and barriers, this thesis subverts …

Examining Relationships Among Body Image, Sexuality, And Sexual Functioning In Women With Cervical And Endometrial Cancer, Christina Wilson

Theses and Dissertations

Introduction: Over 74,000 US women are diagnosed annually with endometrial or cervical cancers and experience significant treatment-related difficulties with body image, sexuality, and sexuality. The aims of the research were to examine relationships among body image, sexuality, and sexual functioning, and understand women’s views of these concepts. A novel theoretical framework encompassing these three concepts and contextual variables guided the research.

Methods: A non-experimental cross-sectional pilot study was conducted with pre-menopausal women in an academic medical center who had stages I-III cervical or endometrial cancer, were 3-36 months post-treatment, and had no mental health diagnoses. Participants completed the …

The Wheel House - An Intergenerational Space Creating Bonds Between At-Risk Teens And Seniors, Jessica M. Keegan

Theses and Dissertations

MOTIVATION

Two main groups in American society today are floundering: adolescent children of low income families and the elderly.

Between the hours of 3:00 and 6:00 p.m., one in five children are unsupervised. Left to their own devices, many become involved in negative behaviors such as drug and alcohol abuse, sexual activity or in the worse cases, delinquency (Afterschool Alliance, 2016). It is proven that when children are alone after school, they not only miss out on valuable learning opportunities, but also their parents are affected as well by having to lose as many as eight work days annually to …

Out Of The Margins: Evolving Narrative Representation Of Women In Video Games, Rowan Lucas

Theses and Dissertations

This thesis examines narrative representation of female characters in video games and how game narratives and representations contribute to socio-cultural discourse. First, this thesis explores and defines the cultural background for female representation in video games. It then defines video games as a type of text and describes the features that are unique to games, such as the use of avatars, and what impacts these features have on game narratives. The thesis attempts to establish evidence of an evolutionary arc of comprehensive female representation in video games by first exploring historical female narrative tropes, and then comparing them to narrative …

Humans Aren't Boxes, Art Isn't Finite, Brianne Alta Humphreys

Theses and Dissertations

I am bored. All around me are systems that perpetuate repetitive, reductive, and mundane modes of living. In an attempt to counter a culture obsessed with singular ways of existence and bite-sized perfection, I utilize moving mediums of video and performance to dive head first into a vast array of sloppy sincerity. The crisp, white-washed, analytical, and restrictive is loudly replaced with the empirical, haphazard, and instinctual. My intention is to create and encourage raw, performative-based work that is as multifaceted as unbridled life itself. This alive and physical practice hosts a conglomeration of sweat, memories, heartbreaks, hymn singing, line …

Alcohol Use And Drinking Motives In Bereaved Undergraduates, Laura J. Smith

Theses and Dissertations

This study examined the effect of the experience of a loss on alcohol use and drinking motives in a college sample. Participants for this study were drawn from the “Spit for Science” project (Dick et al., 2014). The sample included 3,013 students (31.8% men, 68.2% women; 44.3% White, 21.1% Black, 19.6% Asian, 6.0% Latinx; mean age = 18.96; 16.2% bereaved) from Virginia Commonwealth University. Data were collected from participants’ freshman spring and sophomore spring time points on the Life Events Checklist, Alcohol Consumption items, and Drinking Motives Questionnaire-Revised. Participants who were bereaved between the freshman and sophomore timepoint did not …

The Walls We Put Up - Loneliness And Belonging In Urban Co-Living, Richard Rozewski

Theses and Dissertations

ABSTRACT

Concurrent issues of social isolation and loneliness have long been recognized as problems that affect seniors but it is also being proven to affect young people as well, specifically with the rise of new technologies and a perception of connectedness. Co-living provides one alternative design solution to traditional housing models which can unlock a range of social benefits.

MOTIVATION

Loneliness is an unfortunate reality of modern life and it is something that most people experience at least once in their life (Cacioppo & Patrick, 2008). A study carried out by Berguno, Leroux McAinsh, Shaikh (2004), showed that 80% of …

Graphic Intimacies: Identity, Humor, And Trauma In Autobiographical Comics By Women Of Color, Francesca Lyn

Theses and Dissertations

Graphic Intimacies: Identity, Humor, and Trauma in Autobiographical Comics by Women of Color examines works of comics art about the lived experience of the comics’ creator. These graphic narratives address racialized difference and the construction of identity while also using humor to negotiate their narrations of traumatic events. I argue that these creators employ the structure of comics to replicate the fragmentary nature of memory. Comics allow for the representation of trauma as being intimately linked to corporeality. The comics medium allows creators to make visible and present fractured versions of the self, a product of traumatic fragmentation. Drawing traumatic …

Design And Testing Of An Agonist-Antagonist Position-Impedance Controlled Myoelectric Prosthesis, Christopher Aymonin

Theses and Dissertations

Intuitive prosthetic control is limited by the inability to easily convey intention and perceive physical requirements of the task. Rather than providing haptic feedback and allowing users to consciously control every component of manipulation, relegating some aspects of control to the device may simplify operation. This study focuses on the development and testing of a control scheme able to identify object stiffness and regulate impedance. The system includes an algorithm to detect the apparent stiffness of an object, a proportional nonlinear EMG control algorithm for interpreting a user’s desired grasp aperture, and an antagonistically acting impedance controller. Performance of a …

Lotion In Your Lungs, Raul H. De Lara

Theses and Dissertations

This is a document explaining in detail my artistic practice from childhood to the day I graduated VCU. It will perhaps only be understood by those who have themselves already felt such ways, or similar ways – words and ghosts are mostly invisible.

Effects Of The Self- Determined Learning Model Of Instruction On Goal Attainment And Self-Determination For Students With Autism Spectrum Disorder., Meredith M. Moates

Theses and Dissertations

Even with current transition practice and service delivery requirements mandated for students with disabilities by the Individuals with Disabilities Education Act (IDEA, 2004) participation in postsecondary education and employment for individuals with autism remains low (Shattuck et al., 2012; Newman, Wagner, Cameto, & Knokey, 2011). The purpose of this study was to determine the effects of the Self-Determined Learning Model of Instruction (SDLMI; Wehmeyer, Palmer, Agran, Mithaug, & Martin, 2000). The intervention was designed to facilitate student development, and participation in community college course settings, increase academic and vocational goal attainment and self-determined behavior while decreasing support needs. The SDLMI …

An Investigation Of Neurological Soft Signs As A Discriminating Factor Between Veterans With Post-Traumatic Stress Disorder, Mild Traumatic Brain Injury, And Co-Occurring Post-Traumatic Stress Disorder And Mild Traumatic Brain Injury, David J. Rothman

Theses and Dissertations

While multiple Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans suffer from mild Traumatic Brain Injury (mTBI), Post-traumatic Stress Disorder (PTSD), and co-morbid mTBI and PTSD, there remains difficulty disentangling the specific symptoms associated with each disorder using self-report and neurocognitive assessments. We propose that neurological soft signs (NSS), which are tasks associated with general neurologic compromise, may prove useful in this regard. Based on our review of the literature we hypothesized that individuals with PTSD would present with a greater number of NSS than controls or individuals with mTBI. Further, we hypothesized a synergistic effect, such that individuals with …

The Effect Of Music Characteristics On The Novelty And Usefulness Of Creative Ideas., Kathleen Keeler

Theses and Dissertations

This study explores the relationship between music and creativity. Prior research has conflicting results with some finding that music does influence creativity and some reporting no relationship and others finding that music is harmful to creativity. All of these studies, however, have largely focused on the presence vs. absence of music without consideration for the characteristics (i.e., musical key, tempo, etc.) that make up the sound we identify as music and their unique effects on us emotionally, physically, and cognitively. This dissertation contends that different characteristics of music influence different components of creativity (i.e., novelty and usefulness) through their effects …

The Analgesic-Like Properties Of Alcohol In Animal Models Of Chronic Pain, Bradley Neddenriep

Theses and Dissertations

Chronic pain and excessive alcohol consumption are individually problems in our society today. Alcohol Use Disorder (AUD) affects 15.1 million adult Americans each year. Chronic pain affects over 100 million people annually in the United States. However, there is growing evidence suggesting that these two conditions can often be interrelated with chronic pain increasing consumption of alcohol, and excessive alcohol consumption increasing pain that leaves a feedback cycle trapping millions of patients in an ever worsening spiral. Large population-based studies show an association between pain and alcohol abuse, suggesting a link between increased alcohol use and reduced pain. While rodent …

Untitled Unknown, Taylor Simone Stewart

Theses and Dissertations

This article is the first of a series exploring domination culture through the ways narrative has been indoctrinated as reality and weaponized as a holding cell for captives. Within this exploration, the narrative of domination is placed in relation to higher dimensional realms of the unknown; this being the before and after of domination culture. This positioning will allow for the reality of a simultaneous existence within the labyrinth of domination and a higher dimensional unknown to be framed. Within this series of articles, I question the roll of the rogue characters shamanistic agents of resisting domination, the fear of …

The Puppets Look Like Flowers At Last, Evie Metz

Theses and Dissertations

The urge to uncover aspects of human condition permeates my work, from the fundamental curiosity of a child tearing apart their doll to uncover what lies within to continuing a quest in uncovering basic human urges through my puppet animated dramas and tragedies. There is a controversial line between the childlike and the adult-like that can be ambiguous, and at some times more discernible while other times less. I create handcrafted stop-frame puppet animations that explore self-conscious emotions such as embarrassment, shame, and envy within unpredictable life scenarios. These are animations about inner life, attempting to resolve conflicting elements of …

Parallel Narrative: Short-Video Social Media Platforms’ Influences On Contemporary Narrative, Ruiqi Zhang

Theses and Dissertations

Through the study of Kwai, a popular short-video social media platform in China, this thesis investigates the social issues, media class divides and aesthetics specific to Kwai culture. It further proposes a strategy of artistic practice - parallel narrative - an experiment in video art production and editing techniques that explores new possibilities of narrative in video art. Integrating theoretical research on Post-Internet art and object-oriented ontology, this thesis reveals people’s ability to digest multisource information and shows how mobile technologies and open-source materials contribute to the formation of parallel narratives.

Executive Functions As Moderators Of Response To Behavioral Interventions For Adolescents With Attention-Deficit/Hyperactivity Disorder, Stephen J. Molitor

Theses and Dissertations

Adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD) experience significant academic impairment and multiple interventions have been developed to address common academic problems, such as difficulties with homework, organization, and planning skills. Given cost and resource constraints, research is needed on factors that mental health providers can use to select the most appropriate interventions. To date, there has been minimal research evaluating moderators of response to ADHD interventions. Further, many of the variables that have been studied do not have strong theoretical ties to the mechanisms of change invoked by the interventions. This study examined potential moderators of treatment response to two academic …

Group Decision-Making, Edward Cook

Theses and Dissertations

The present work explores improvements in group decision-making. It begins with a practical example using state-of-the-art techniques for a complex, high-risk decision. We show how these techniques can reveal a better alternative. Although we created an improved decision process, decision-makers were apt to protect their own organizations instead of the project. This tendency was reduced over the course of the decision-making process but inspired the first conceptual component of this work.

The first concept describes the “Cost of Conflict” that can arise in a group decision, using game theory to represent the non-cooperative approach and comparing the outcome to the …

The Efficacy Of A Group Visual Art Bereavement Intervention With Older Adults, Rachel E. Weiskittle

Theses and Dissertations

Research on expressive art interventions for bereavement has burgeoned in recent years. Studies have supported their effectiveness in facilitating participants’ adjustment to loss (e.g., Rosner, Kruse, & Hagl, 2010; Uttley, 2015) and have revealed the frequency with which they are clinically implemented (Thompson & Neimeyer, 2014). Clinicians and recipients of expressive art interventions advocate for their helpfulness in grief processing (e.g., Gamino, 2015). Publications have highlighted particular visual art modules that facilitate adaptive adjustment to loss by providing avenues for self-expression, meaning making and continuing bonds with the deceased (Neimeyer, 2016), but few studies have quantitatively investigated whether they improve …

The Role Of Mindfulness In Self-View Investment: Neural And Subjective Indicators, Hadley Rahrig

Theses and Dissertations

Self-concept is strongly influenced by beliefs about one’s personal psychological attributes, and these beliefs are held with varying degrees of confidence and consequence. Hence, it is investment in self-views of those attributes that helps to regulate and maintain stable self-concept. Self-view investment is relevant to numerous self-related functions, but high self-view investment can also contribute to maladaptive self-views. Theory suggests that mindfulness cultivates a less personal, more objective perception of one’s thoughts, emotions and behaviors, and training in mindfulness has been shown to alter self-referential processing. The current pilot study (N=21) investigates the possible role of dispositional mindfulness in two …
