"Joy For What It Is": Narratives Of Two Mothers On Raising Their Children With Disabilities, Zeina H. Yousof

Dissertations and Theses @ UNI

The purpose of this study was to explore the experiences of two mothers of children with disabilities on parenting their children and navigating the world of disabilities. For many parents, the diagnosis of a child with disabilities represents a form of interpersonal loss through the loss of the imagined child. Mothers are often identified as the primary caregivers of their children with disabilities and are often at the front-end of seeking, providing, and advocating for medical, education, and social services.

Employing qualitative research methods, autoethnography and narrative inquiry were used to reveal the mothers’ experiences. Through conversational interviews and journaling, …

Remembering Harvey Goldschmid, David M. Schizer

Faculty Scholarship

For me, Harvey Goldschmid and Columbia are inextricably connected. I can't think of one without the other. Harvey discovered his passion for learning as a student at the college and the law school. Only five years after graduating, Harvey returned to Columbia to join our faculty, serving for four and a half decades. When we add this time to his time as a student, it's fifty-two years. That's over 70% of his life.

But Harvey's connection to Columbia was not just long; it was deep. I can't count the number of graduates over the years who've told me he was …

Severity Of Spinal Cord Injury Influences Diffusion Tensor Imaging Of The Brain, Michael B. Jirjis, Aditya Vedantam, Matthew D. Budde, Benjamin Kalinosky, Shekar N. Kurpad

Biomedical Engineering Faculty Research and Publications

Background: The purpose of this study was to determine whether DTI changes in the brain induced by a thoracic spinal cord injury are sensitive to varying severity of spinal contusion in rats.

Methods: A control, mild, moderate, or severe contusion injury was administered over the eighth thoracic vertebral level in 32 Sprague-Dawley rats. At 11 weeks postinjury, ex vivo DTI of the brain was performed on a 9.4T Bruker scanner using a pulsed gradient spin-echo sequence.

Results: Mean water diffusion in the internal capsule regions of the brain and pyramid locations of the brainstem were correlated with motor function (r …

Material And Structural Aspects Of Bone In Osteogenesis Imperfecta, Carolyne Albert, John Jameson, Peter Smith, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

Bone fragility is a fundamental problem in individuals with osteogenesis imperfecta (OI). The mechanisms behind this fragility, however, are not yet well understood. Multiple factors appear to contribute to the increased fracture risk in OI. At the structural level, bone mass deficiency can result in increased stress levels within bones. The underlying mineral and collagen abnormalities that define OI are also believed to result in compromised material-level properties. The variability of collagen biochemical irregularities causing OI and the corresponding heterogeneity of disease severity result in abnormalities that are not easily generalized within the OI population.

The aims of this chapter …

Motion Analysis Strategy Appropriate For 3d Kinematic Assessment Of Children And Adults With Osteogenesis Imperfecta, Jeffrey D. Kertis, Jessica M. Fritz, Sergey Tarima, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

Human motion analysis provides a quantitative means of assessing whole body and segmental motion of subjects with musculoskeletal pathologies. This chapter describes a low cost motion analysis appropriate for complete three-dimensional (3D) assessment of upper and lower extremity kinematics. The system has been designed to support lower cost outreach efforts that require accuracy and resolution on the order of classical fixed lot systems such as Vicon.

Quantitative Assessment Of Children With Osteogenesis Imperfecta, Adam Graf, Joseph Krzak, Angela Caudill, Ann Flanagan, Peter Smith, Gerald F. Harris

Biomedical Engineering Faculty Research and Publications

Assessments of children with Osteogenesis Imperfecta (OI) are typically limited to a physical exam and observations from a clinician during a hospital visit. Often quantitative information such as bone mineral density and outcome questionnaires is obtained, but with the increasing prevalence of motion analysis and other performance type laboratories, there are many other tools available, which could be beneficial to this patient population. These laboratories can provide date supplementary to morphologic and radiographic data that is helpful in tracking changes in the patient’s functional abilities, recover from fracture, and treatment outcomes. This chapter will cover some useful evaluation methods for …

Motor Output Variability Impairs Driving Ability In Older Adults, Neha Lodha, Hwasil Moon, Changki Kim, Tanya Onushko, Evangelos A. Christou

Biomedical Engineering Faculty Research and Publications

Background: The functional declines with aging relate to deficits in motor control and strength. In this study, we determine whether older adults exhibit impaired driving as a consequence of declines in motor control or strength.

Methods: Young and older adults performed the following tasks: (i) maximum voluntary contractions of ankle dorsiflexion and plantarflexion; (ii) sinusoidal tracking with isolated ankle dorsiflexion; and (iii) a reactive driving task that required responding to unexpected brake lights of the car ahead. We quantified motor control with ankle force variability, gas position variability, and brake force variability. We quantified reactive driving performance with a combination …

Juvenile Sentencing Reform In A Constitutional Framework, Elizabeth S. Scott, Thomas Grisso, Marsha Levick, Laurence Steinberg

Faculty Scholarship

In the past decade, the Supreme Court has transformed the constitutional landscape of juvenile crime regulation. In three strongly worded opinions, the Court held that imposing harsh criminal sentences on juvenile offenders violates the Eighth Amendment prohibition against cruel and unusual punishment. Roper v Simmons in 2005 prohibited the imposition of the death penalty for a crime committed by a juvenile. Five years later, Graham v. Florida held that no juvenile could be sentenced to life without the possibility of parole (LWOP) for a nonhomicide offense. Then in 2012, Miller v. Alabama struck down statutes that required courts to sentence …

Lessons Learned From A 10-Year Collaboration Between Engineering And Industrial Design Students In Capstone Design Projects, Jay R. Goldberg, Pascal Malassigné

Biomedical Engineering Faculty Research and Publications

Engineers and industrial designers have different approaches to problem solving. Both place heavy emphasis on identification of customer needs, manufacturing methods, and prototyping. Industrial designers focus on aesthetics, ergonomics, ease of use, and the user’s experience. They tend to be more visual and more concerned with the interaction between users and products. Engineers focus on functionality, performance requirements, analytical modeling, and design verification and validation. They tend to be more analytical and more concerned with the design of internal components and product performance. Engineers and industrial designers often work together on project teams in industry. Collaboration between the two groups …

Smartphone Microendoscopy For High Resolution Fluorescence Imaging, Xiangqian Hong, Vivek K. Nagarajan, Dale H. Mugler, Bing Yu

Biomedical Engineering Faculty Research and Publications

High resolution optical endoscopes arc increasingly used in diagnosis of various medical conditions of internal organs, such as the cervix and gastrointestinal (GI) tracts, but they are too expensive for use in resource-poor settings. On the other hand, smartphones with high resolution cameras and Internet access have become more affordable, enabling them to diffuse into most rural areas and developing countries in the past decade. In this paper, we describe a smartphone microendoscope that can take fluorescence images with a spatial resolution of 3.1 μm. Images collected from ex vivo, in vitro and in vivo samples using the device …

Young Adulthood As A Transitional Legal Category: Science, Social Change, And Justice Policy, Elizabeth S. Scott, Richard J. Bonnie, Laurence Steinberg

Faculty Scholarship

In the past decade, much attention has focused on developmental brain research and its implications for the regulation of crime. Public and policy interest has been directed primarily toward juveniles. In light of recent research, courts and legislatures increasingly have rejected the punitive response of the 1990s and embraced a developmental approach to young offenders. Of particular importance in propelling this trend has been the framework offered by the U.S. Supreme Court in a series of Eighth Amendment opinions that have rejected harsh adult sentences for juveniles. These decisions, supported by adolescent brain research, rested on two empirically based principles: …

The Common Law Of Contract And The Default Rule Project, Alan Schwartz, Robert E. Scott

Faculty Scholarship

The common law developed over centuries a small set of default rules that courts have used to fill gaps in otherwise incomplete contracts between commercial parties. These rules can be applied almost independently of context: the market damages rule, for example, requires a court only to know the difference between market and contract prices. When parties in various sectors of the economy write sales contracts but leave terms blank, courts fill in the blanks with their own rules. As a consequence, a judicial rule that many parties accept must be "transcontextual": parties in varied commercial contexts accept the courts' rule …

How Undergraduates' Involvement Affects Sense Of Belonging In Courses That Use Technology, Leroy L. Long Iii

Publications

In order to increase the number of American degree recipients in science, technology, engineering and mathematics (STEM), academics must continually develop ways to improve students’ interest, retention, and success in fields like engineering. Prior researchers have studied the use of educational technology as a way to improve student outcomes and skills. Previous scholars have also investigated students’ perceptions of the usefulness of technology. However, it is unclear if a statistically significant relationship exists between students’ involvement in courses that use technology and their sense of belonging to others on campus. The present study addressed this gap by examining the relationship …

During the fall of 2014 and 2015, one large public university in the Midwest with more selective admission criteria decided to pilot a course based on the Wright State Model for Engineering Mathematics Education. Using the Wright State model, a mathematics for engineering course was offered to prospective students so …

The U.S. Airways Group: A Post-Merger Analysis, Wilfred S. Manuela Jr., Dawna L. Rhoades, Tamilla Curtis

Publications

America West Airlines acquired the bankrupt US Airways on September 27, 2005 to form the US Airways Group. Our paper analyzes the post-merger performance of the US Airways Group using airline operating metrics and financial ratios for the period 2005 to 2013. While the airline has still a long way to go to improve its leverage and liquidity ratios, its capital structure and ability to pay its obligations have improved since 2005. Moreover, although the airline is still inefficient in utilizing its assets, the efficiency improvements achieved since the merger have resulted in profits and positive returns to investors. Its …

Students' Perception Of The Flipped Classroom In Graphical Communications, Lulu Sun

Publications

The flipped classroom requires students to study concepts before the class, apply what they learn in the classroom, and work with other students, which then makes it possible to get immediate feedback from the instructor. However, the student’s perception of the flipped classroom is not widely investigated in the area of engineering graphics. This paper presents a study of the flipped classroom in a Graphical Communications course. Students are required to study course material online before the face-to-face classroom experience. The online course study includes multimedia materials and an online quiz that they are required to take. The results of …

Animal Mourning: Précis Of How Animals Grieve (King 2013), Barbara J. King

Animal Sentience

Abstract: When an animal dies, that individual’s mate, relatives, or friends may express grief. Changes in the survivor’s patterns of social behavior, eating, sleeping, and/or of expression of affect are the key criteria for defining grief. Based on this understanding of grief, it is not only big-brained mammals like elephants, apes, and cetaceans who can be said to mourn, but also a wide variety of other animals, including domestic companions like cats, dogs, and rabbits; horses and farm animals; and some birds. With keen attention placed on seeking where grief is found to occur and where it is absent …

Death In The Family, Maria Botero

Animal Sentience

Barbara King presents grief as the result of the capacity of human and non-human animals for social and affectionate bonds. This is a novel approach that provides a context for interpreting behavioral evidence of grief. The book also offers thought-provoking insights into the relationship between emotion and the expression of emotion. The most surprising element of King’s approach is that, throughout the book, her account of non-human animal grief forces us to reassess the way we treat them.

Considering Animals’ Feelings: Précis Of Sentience And Animal Welfare (Broom 2014), Donald M. Broom

Animal Sentience

The concept of sentience concerns the capacity to have feelings. There is evidence for sophisticated cognitive concepts and for both positive and negative feelings in a wide range of nonhuman animals. All vertebrates, including fish, as well as some molluscs and decapod crustaceans have pain systems. Most people today consider that their moral obligations extend to many animal species. Moral decisions about abortion, euthanasia, and the various ways we protect animals should take into account the research findings about sentience. In addition, all animal life should be respected and studies of the welfare of even the simplest invertebrate animals should …

From Sentience To Science: Limits Of Anthropocentric Cognition, Charukeshi Chandrasekera

Animal Sentience

Donald Broom’s Sentience and Animal Welfare (2014) is an intellectually and morally engaging book written with radical new concepts in mind. It deals with many issues that are central to the animal welfare debate such as brain complexity, cognitive ability, when in life sentience begins, and how it all affects the way we endorse welfare. It addresses how our insatiable quest to define the uniqueness of our own species has led us to ignore logic and scientific evidence. It also brings greater clarity to these precarious positions and outlines pragmatic approaches to tackling this complex topic of sentience and welfare.

Is Sentience Only A Nonessential Component Of Animal Welfare?, Ian J.H. Duncan

Animal Sentience

According to Broom (2014), animal welfare is a concept that can be applied to all animals, including single-celled organisms that are obviously not sentient. Such a stance makes it difficult to draw a connection between welfare and sentience, and that is the book’s downfall. Some excellent points are made about sentience and there are very good discussions on animal welfare. However, unless sentience is considered the essential component of welfare, any attempt to link the two phenomena will be unsuccessful — and that, indeed, is the case with this book.

The Science Of Sentience Is Reshaping How We Think About Animals, Debra Durham

Animal Sentience

Broom’s Sentience and Animal Welfare (2014) provides its readers with an excellent overview of the evolving role of sentience in our understanding animal welfare as well as insights into why sentience matters for practice and policy.

Sentience And Animal Welfare: New Thoughts And Controversies, Donald M. Broom

Animal Sentience

Sentience involves having some degree of awareness but awareness of self is not as complex as some people believe. Fully functioning vertebrate animals, and some invertebrates, are sentient but neither humans nor non-humans are sentient early in development or if brain-damaged. Feelings are valuable adaptive mechanisms and an important part of welfare but are not all of welfare so the term welfare refers to all animals, not just to sentient animals. We have much to learn about what non-human animals want from us, the functioning of the more complex aspects of their brains and of our brains and how we …

Micro Cavitation Bubbles On The Movement Of An Experimental Submarine: Theory And Experiments, S.C. Mancas, Shahrdad G. Sajjadi, Asalie Anderson, Derek Hoffman

Publications

To understand the nature of movement of submarine, micro cavitation bubbles were systematically diffused around the exterior of a test body (tube) fully submerged in a water tank. The primary purpose was to assess the feasibility of applying micro cavitation as a means of depth control for underwater vehicles, mainly but not limited to submarines. Ideally, the results would indicate the use of micro cavitation as a more efficient alternative to underwater vehicle depth control than the conventional ballast tank method. The current approach utilizes the Archimedes' principle of buoyancy to alter the density of the object affected, making it …

Plasma Density Analysis Of Cubesat Wakes In The Earth’S Ionosphere, Robert M. Albarran Ii, Aroh Barjatya

Publications

Spinning or tumbling CubeSats with Langmuir probes deployed on booms will render spin-modulated plasma densities as the probes move in and out of the spacecraft wake. It is traditionally assumed that the lower-density measurements from the spin cycle are made in the spacecraft wake, and the higher-density measurements are outside the wake. Although this assumption is valid for larger spacecraft in the Earth’s ionosphere, this paper scrutinizes its validity for CubeSats in similar conditions. Spacecraft–plasma interactions (surface charging, plasma sheaths, and wakes) are less understood for CubeSats, and the small CubeSat dimensions must be considered with respect to characteristic length …

What Are The Predictors Of System-Wide Trust Loss In Transportation Automation?, Stephen Rice, Scott R. Winter, John E. Deaton, Ismael Cremer

Publications

Prior research has examined how individuals place trust in single (e.g., Meyer, 2001, 2004) and multiple (e.g., Geels-Blair, Rice, & Schwark, 2013) automated devices when one fails. This has shown that participants are influenced by system-wide trust (SWT). What has been missing is an investigation into what types of people succumb to SWT effects. The current study attempts to replicate SWT findings and identify possible predictors of individuals likely to be influenced by SWT. The findings did demonstrate a replication of SWT. The study found that ‘‘feelings of negativity when automated devices fail’’ was a significant predictor of SWT theory.
