Engineering Challenges In High School Stem Courses: A Compilation Of Invited Position Papers, Dan L. Householder

Engineering Education Faculty Publications

Since its initial funding by the National Science Foundation in 2004, the National Center for Engineering and Technology Education (NCETE) has worked to understand the infusion of engineering design experiences into the high school setting. Over the years, an increasing number of educators and professional groups have participated in the expanding initiative seeking to acquaint all students with engineering design. While there is strong support for providing students with engineering design experiences in their high school STEM courses, the lack of consensus on purposes and strategies has become increasingly apparent as the work continues. Among the unsettled issues are the …

Anomalous Diffraction Approach To The Visible Spectra Of Absorption By Marine Particles With Power-Law Size Distributions, Maciej Matciak, Bożena Wojtasiewicz

Journal of Marine Research

The spectral shape of the light absorption by marine particles with power-law size distribution was analyzed. The anomalous diffraction approximation (ADA) in its conventional form for optically “soft” homogenous particles was used to model the absorption cross section. Based on this theory, particular formulas describing the spectral shape of absorption of an assemblage of particles were derived. Exemplary calculations were performed for particles of selected shapes (spheres, thin cylinders and disks). The results suggest that relative absorption spectra of marine particles in many cases can be approximated by a simple formula, i.e. a power function of the ratio of their …

Linear Instability Of Uniform Shear Zonal Currents On The Β-Plane, Nathan Paldor, Yona Dvorkin, Doron Nof

Journal of Marine Research

A unified formulation of the instability of a mean zonal flow with uniform shear is proposed, which includes both the coupled density front and the coastal current. The unified formulation shows that the previously found instability of the coupled density front on the f-plane has natural extension to coastal currents, where the instability exists provided that the net transport of the current is sufficiently small. This extension of the coupled front instability to coastal currents implies that the instability originates from the interaction between Inertia-Gravity waves and a vorticity edge wave and not from the interaction of the two …

Primary And Secondary Intrusions In Double-Diffusively Stable Vertical Gradients, Julian A. Simeonov

Journal of Marine Research

The purpose of this paper is to show that molecularly-driven double-diffusive intrusions can produce significant lateral and vertical double-diffusive mixing even when the initial temperature and salinity are both stably stratified in the vertical. Assuming uniform density-compensated horizontal gradients and periodic disturbances, three-dimensional direct numerical simulations (DNS) for the fastest growing intrusion show that the latter equilibrates due to the generation of salt fingers which reduce the driving buoyancy pressure gradient. The DNS also provided statistical data for a new parameterization of the salt finger fluxes which includes the effects of shear and variable vertical gradients. This parameterization makes it …

Suffering Transfigured: Phenomenological Personalism In The Doctor-Patient Relationship, Keri Oxley

Yale Medicine Thesis Digital Library

From antiquity, one of the primary goals of medicine has been the alleviation of patients' suffering. Despite remarkable advances in modern science and technology, patients continue to experience suffering, which is frequently unnoticed and unaddressed by physicians.

Phenomenology incorporates an understanding of illness-as-lived, which provides the physician with a view more expansive than the purely biomedical model of disease. There exists a decisive gap between the way a physician thinks about disease and the way illness is experienced by the patient. As a result, there is a separation between the "lifeworlds" of the physician and patient. A fuller description of …

A Human Culture Model Of The Outer Blood-Retinal Barrier In Age-Related Macular Degeneration, Veena Rao

Yale Medicine Thesis Digital Library

In age-related macular degeneration (AMD), the outer blood-retinal barrier is exposed to various pathologic factors which can result in visual detriment. Two such stimuli include serum, as may be seen in neovascular AMD, and proinflammatory cytokines, which may be seen in neovascular and non-neovascular AMD. To examine effects of serum and cytokines in disease, we adapted an outer blood-retinal barrier culture model using human fetal retinal pigment epithelium (hfRPE) to investigate effects on tight junctions. Specifically, we focused on the claudin family and occludin tight junction proteins. HfRPE was cultured on filters in growth medium until quiescent monolayers were formed; …

Femoral Loading Mechanics In The Virginia Opossum (Didelphis Virginiana): Torsion And Mediolateral Bending In Mammalian Locomotion, W. Casey Gosnell, Michael T. Butcher, Takashi Maie, Richard W. Blob

Publications

Studies of limb bone loading in terrestrial mammals have typically found anteroposterior bending to be the primary loading regime, with torsion contributing minimally. However, previous studies have focused on large, cursorial eutherian species in which the limbs are held essentially upright. Recent in vivo strain data from the Virginia opossum (Didelphis virginiana), a marsupial that uses a crouched rather than an upright limb posture, have indicated that its femur experiences appreciable torsion during locomotion as well as strong mediolateral bending. The elevated femoral torsion and strong mediolateral bending observed in D. virginiana might result from external forces such as a …

Loading Mechanics Of The Femur In Tiger Salamanders (Ambystoma Tigrinum) During Terrestrial Locomotion., K. Megan Sheffield, Richard W. Blob

Publications

Salamanders are often used as representatives of the basal tetrapod body plan in functional studies, but little is known about the loads experienced by their limb bones during locomotion. Although salamanders' slow walking speeds might lead to low locomotor forces and limb bone stresses similar to those of non-avian reptiles, their highly sprawled posture combined with relatively small limb bones could produce elevated limb bone stresses closer to those of avian and mammalian species. This study evaluates the loads on the femur of the tiger salamander (Ambystoma tigrinum) during terrestrial locomotion using three-dimensional measurements of the ground reaction force (GRF) …

Forelimb Kinematics And Motor Patterns Of Swimming Loggerhead Sea Turtles (Caretta Caretta): Are Motor Patterns Conserved In The Evolution Of New Locomotor Strategies? , Angela R.V. Rivera, Jeanette Wyneken, Richard W. Blob

Publications

Novel functions in animals may evolve through changes in morphology, muscle activity or a combination of both. The idea that new functions or behavior can arise solely through changes in structure, without concurrent changes in the patterns of muscle activity that control movement of those structures, has been formalized as the neuromotor conservation hypothesis. In vertebrate locomotor systems, evidence for neuromotor conservation is found across evolutionary transitions in the behavior of terrestrial species, and in evolutionary transitions from terrestrial species to flying species. However, evolutionary transitions in the locomotion of aquatic species have received little comparable study to determine whether …

Hydrodynamic Stability Of The Painted Turtle (Chrysemys Picta): Effects Of Four-Limbed Rowing Versus Forelimb Flapping In Rigid-Bodied Tetrapods. , Gabriel Rivera, Angela R.V. Rivera, Richard W. Blob

Publications

Hydrodynamic stability is the ability to resist recoil motions of the body produced by destabilizing forces. Previous studies have suggested that recoil motions can decrease locomotor performance, efficiency and sensory perception and that swimming animals might utilize kinematic strategies or possess morphological adaptations that reduce recoil motions and produce more stable trajectories. We used high-speed video to assess hydrodynamic stability during rectilinear swimming in the freshwater painted turtle (Chrysemys picta). Parameters of vertical stability (heave and pitch) were non-cyclic and variable, whereas measures of lateral stability (sideslip and yaw) showed repeatable cyclic patterns. In addition, because freshwater and marine turtles …

Locomotor Loading Mechanics In The Hindlimbs Of Tegu Lizards (Tupinambis Merinae): Comparitive And Evolutionary Implications, K. Megan Sheffield, Michael T. Butcher, S. Katherine Shugart, Jennifer C. Gander, Richard W. Blob

Publications

Skeletal elements are usually able to withstand several times their usual load before they yield, and this ratio is known as the bone's safety factor. Limited studies on amphibians and non-avian reptiles have shown that they have much higher limb bone safety factors than birds and mammals. It has been hypothesized that this difference is related to the difference in posture between upright birds and mammals and sprawling ectotherms; however, limb bone loading data from a wider range of sprawling species are needed in order to determine whether the higher safety factors seen in amphibians and non-avian reptiles are ancestral …

Biodiesel Production From Crude Cottonseed Oil: An Optimization Process Using Response Surface Methodology, Xiaohu Fan, Xi Wang, Feng Chen

Publications

Biodiesel, known as fatty acid methyl ester (FAME), was produced from crude cottonseed oil (triglycerides) by transesterification with methanol in the presence of sodium hydroxide. This process was optimized by applying factorial design and response surface methodology (RSM) with SAS and PSIPLOT programs. A second-order mathematical model was obtained to predict the yield as a function of methanol/oil molar ratio, catalyst concentration, reaction temperature, and rate of mixing. Based on ridge max analysis and RSM, as well as economic cost consideration, the practical optimal condition for the production of biodiesel was found to be: methanol/oil molar ratio, 7.9; temperature, 53 …

Improving Our Legacy: Incorporation Of Adaptive Management Into State Wildlife Action Plans, Joseph J. Fontaine

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

The loss of biodiversity is a mounting concern, but despite numerous attempts there are few large scale conservation efforts that have proven successful in reversing current declines. Given the challenge of biodiversity conservation, there is a need to develop strategic conservation plans that address species declines even with the inherent uncertainty in managing multiple species in complex environments. In 2002, the State Wildlife Grant program was initiated to fulfill this need, and while not explicitly outlined by Congress follows the fundamental premise of adaptive management, ‘Learning by doing’. When action is necessary, but basic biological information and an understanding of …

APIAS Research Report 研究報告

Modernization marked the progress of society and posed various changes to human life as well as the epidemiological transition. Improvements in public health care, living conditions, income and the control of infectious diseases were important factors in the first half of the twentieth century that led to the increases in life expectancy, while in the second half it was improvements in social conditions, health technologies such as antibiotics, and widespread immunization. The existences of advanced medical services effectively get rid of the prevalence of infectious disease that caused immediate human threats such as Measles and Smallpox.

Given that technological advancement …

Can Law Improve Prevention And Treatment Of Cancer?, Roger Magnusson, Lawrence O. Gostin, David Studdert

O'Neill Institute Papers

The December 2011 issue of Public Health (the Journal of the Royal Society for Public Health) contains a symposium entitled: Legislate, Regulate, Litigate? Legal approaches to the prevention and treatment of cancer. This symposium explores the possibilities for using law and regulation – both internationally and at the national level – as the policy instrument for preventing and improving the treatment of cancer and other leading non-communicable diseases (NCDs). In this editorial, we argue that there is an urgent need for more legal scholarship on cancer and other leading NCDs, as well as greater dialogue between lawyers, public health practitioners …

Examining The Rapid Non-Classical Effects Of 17 Beta Estradiol On Sexual Advertisement Behavior Of The Golden Hamster (Mesocricetus Auratus), John T. Garretson, Spencer L. Gobbel, Christine M. Lewis, Luis A. Martinez, Aras Petrulis

Modern Psychological Studies

Female Syrian hamsters engage in vaginal scent-marking (VM) to advertise their sexual receptivity. VM is facilitated by estrogen; however, the hormone's mechanism of action is unknown. Classically, estrogen binds to intracellular receptors and promotes gene transcription to eventually affect behavior. Estrogen may non-classically and rapidly affect behavior via binding to membrane localized receptors. In order to determine how estrogen modulates VM, VM levels were examined in 10 female hamsters across several hormone conditions. Levels of VM were assessed across 3 trials in intact, normally-cycling subjects. These trials were repeated following ovariectomy. A final set of trials were conducted in ovariectomized …

Gender Difference In Perceiving Aggression Using The Bobo Doll Studies, Dorothy Altin, Jessica Jablonski, Jennifer Lyke, Marcello Spinella

Modern Psychological Studies

The general conclusion of Albert Bandura's Bobo Doll studies was that the children learned aggression through watching an adult hit an inflatable doll. Other researchers have questioned whether the behavior demonstrated in these studies was actual aggression or just simply imitation. This study examined the perceptions of male and female observers when viewing original footage of the Bobo Doll Studies, specifically if the observers interpreted the child's behavior as aggression or simply imitation and if the sex of the observer or sex of the child in the video affected these ratings. The participants completed both a Likert scale rating of …

“Getting Noticed”: Middle Childhood Incross-Cultural Perspective, David F. Lancy, M. Annette Grove

Sociology, Social Work and Anthropology Faculty Publications

Although rarely named, the majority of societies in the ethnographic record demarcate a period between early childhood and adolescence. Prominent signs of demarcation are: for the first time, pronounced gender separation in fact and in role definition; increased freedom of movement for boys while girls may be bound more tightly to their mothers; and heightened expectations for socially responsible behavior. But, above all, middle childhood is about coming out of the shadows of community life and assuming a distinct, lifetime character. Naming and other rites of passage sometimes acknowledge this transition, but it is, reliably, marked by the assumption or …

A Topological Approach To Molecular Chirality, Erica Flapan

Pomona Faculty Publications and Research

Topology is the study of deformations of geometric figures. Chemistry is the study of molecular structures. At first glance these fields seem to have nothing in common. But let’s take a closer look to see how these fields come together in the study of molecular symmetries.

Seeing The Forest For The Trees: Managing Social Conflict And Forest Restoration, Steven E. Daniels, Jens Emborg, Greg B. Walker

Sociology, Social Work and Anthropology Faculty Publications

This paper examines the role that social conflict is likely to play in forest restoration projects. A definition of conflict as “perceived goal interference among interdependent parties” serves as a point of departure for the discussion, and the nature of forest restoration conflict is systematically examined by focusing on each aspect of the definition: perceptions, goal interference, the parties, and their interdependence. Agencies undertaking restoration projects are encouraged to adopt a discourse orientation, wherein they recognize that 1) their public involvement efforts are creating a discourse that can incorporate a wide array of values and voices and 2) groups may …

An Ecological Analysis Of Social And Economic Influences On Black And White Infant Mortality Risk In Orange County, Fl, Littleton, Vanessa Lopez

Electronic Theses and Dissertations

Black health disparities are a salient public health issue with blacks in every socioeconomic level at a greater health disadvantage than their white counterparts. In particular, disparity in infant mortality rates between blacks and whites have widened in recent decades to differentials never before experienced in the United States. Social ecologists investigating the myriad of individual and environmental risk factors have failed to fully account for the persistent differential. This study examines the relationships between individual and environmental influences on the health risk experienced by blacks, whites, as well as the differential between the two populations. This multi-level analysis was …

Harmony Oriented Architecture, Kyle A. Martin

Electronic Theses and Dissertations

This thesis presents Harmony Oriented Architecture: a novel architectural paradigm that applies the principles of Harmony Oriented Programming to the architecture of scalable and evolvable distributed systems. It is motivated by research on Ultra Large Scale systems that has revealed inherent limitations in human ability to design large-scale software systems that can only be overcome through radical alternatives to traditional object-oriented software engineering practice that simplifies the construction of highly scalable and evolvable system. HOP eschews encapsulation and information hiding, the core principles of objectoriented design, in favor of exposure and information sharing through a spatial abstraction. This helps to …
