Psychological Sense Of Community And Retention: Rethinking The First-Year Experience Of Students In Stem, Melissa Dagley Falls

Electronic Theses and Dissertations

This investigation looks at the relationship between a STEM learning community's co-curricular activities and students' perceived sense of community (SOC)to determine which activities most influence SOC and, in turn, retention. This investigation shows that SOC can be impacted by a multitude of factors found within the college environment. The most influential of these factors are open acceptance, student academic support services, and residential experiences. Most importantly there were significant differences for African American students participating in the STEM learning community on the measures of SOC, retention, and being on-track in mathematics. Additional data suggested higher levels of being on-track in …

Linking Place Value Concepts With Computational Practices In Third Grade, Terry Cuffel

Electronic Theses and Dissertations

In an attempt to examine student understanding of place value with third graders, I conducted action research with a small group of girls to determine if my use of instructional strategies would encourage the development of conceptual understanding of place value. Strategies that have been found to encourage conceptual development of place value, such as use of the candy factory, were incorporated into my instruction. Instructional strategies were adjusted as the study progressed to meet the needs of the students and the development of their understanding of place value. Student explanations of their use of strategies contributed to my interpretation …

Computational Analysis Of Ultraviolet Reactors, Xiang Li

Theses

Disinfection of water treatment using ultraviolet (UV) light has received wide recognition as an important contribution to the protection of public health. To ensure a UV disinfection system that can deliver the required UV dose, analytical and numerical methods have been used to evaluate the flow field of the UV reactor. A Multiple Point Source Summation (MPSS) method was used to estimate the radiation intensity field, with the utilization of Computational Fluid Dynamics (CFD) technique. To couple the analytical model with numerical simulations, a user friendly interface software was developed to calculate the UV dosage distribution. In addition a UV …

Modeling Problems In Mucus Viscoelasticity And Mucociliary Clearance, Michael M. Norton

Theses

From the common cold and allergies to severe chronic and acute respiratory impairments, the function of the body's mucociliary clearance mechanism plays a primary defense role. Mucus demonstrates numerous non-Newtonian behaviors which set it apart from viscous fluids. Among them: Bingham plastic behavior, shear-thinning, and elasticity on short time scales due to relaxation time. Experimental evidence suggests that certain rheologies promote effective transport. In an effort to reveal the mechanisms controlling transport, models are developed. Firstly, a steady state model which idealizes the mucus as a rigid body is created in order to bring together disparate bodies of experimental work …

The Resilience Of Law, Joseph Vining

Book Chapters

One of the striking developments in academic law in the past half century is the reconception of law as one of the social sciences. The idea at work in this movement, as Joseph Vining says in this essay, is not that the law should use the findings of other disciplines for its own purposes and in its own way, but that in some deep way law itself - legal thinking, legal life - can and ought to proceed on the premises of social science, indeed of science itself. This is in one sense obviously impossible: a scientific rule is a …

The Patient Life: Can Consumers Direct Health Care?, Carl E. Schneider, Mark A. Hall

Articles

The ultimate aim of health care policy is good care at good prices. Managed care failed to achieve this goal through influencing providers, so health policy has turned to the only market-based option left: treating patients like consumers. Health insurance and tax policy now pressure patients to spend their own money when they select health plans, providers, and treatments. Expecting patients to choose what they need at the price they want, consumerists believe that market competition will constrain costs while optimizing quality. This classic form of consumerism is today's health policy watchword. This article evaluates consumerism and the regulatory mechanism …

A Viable Model And Self-Report Measure Of Spiritual Intelligence, David B. King, Teresa L. Decicco

International Journal of Transpersonal Studies

A four-factor model of spiritual intelligence is first proposed. Supportive evidence is reviewed for the

capacities of critical existential thinking, personal meaning production, transcendental awareness,

and conscious state expansion. Based on this model, a 24-item self-report measure was developed

and modified across two consecutive studies (N = 619 and N = 304, respectively). The final version

of the scale, the Spiritual Intelligence Self-Report Inventory (SISRI-24), displayed excellent internal

reliability and good fit to the proposed model. Correlational analyses with additional measures of

meaning, metapersonal self-construal, mysticism, religiosity, and social desirability offer support

for construct and criterion-related validity. According to both …

An Analysis Of The Impact Of Information Security Policies On Computer Security Breach Incidents In Law Firms, Faith M. Heikkila

CCAC Theses and Dissertations

Law firms maintain and store voluminous amounts of highly confidential and proprietary data, such as attorney-client privileged information, intellectual properties, financials, trade secrets, personal, and other sensitive information. There is an ethical obligation to protect law firm client data from unauthorized access. Security breaches jeopardize the reputation of the law firm and could have a substantial financial impact if these confidential data are compromised. Information security policies describe the security goals of a law firm and the acceptable actions and uses of law firm information resources.

In this dissertation investigation, the author examined the problem of whether information security policies …

An Investigation Of Training In Creative Problem Solving And Its Relationship To Affective And Effective Idea Generation Of Entrepreneurial Learners, Charles Edward Leach

CCAC Theses and Dissertations

A significant proportion of the population engages in entrepreneurial behavior but many ventures do not survive beyond startup thus decreasing the pool of entrepreneurs available to contribute to the economy. Opportunity recognition is central to entrepreneurial success and the improper delineation of opportunities is cited as a leading cause of venture failure. There is a logical link between creativity, innovation and entrepreneurship. The goal of the researcher in this study was to explore the relationships between CPS training and the generation of entrepreneurial ideas.

The investigation studied the relationship of training in creative problem solving (CPS) to the opportunity identification …

Administrative Support For Online Teaching Faculty, John David Meyer

CCAC Theses and Dissertations

When administrators make decisions about the infrastructure support needs of a current or planned online teaching program, these decisions are often based on external expert advice rather than on the advice of experienced ground level faculty who are living with the dynamic nature of the technology and support needed to develop and maintain an effective online teaching program. Online teaching faculty are the best source of advice and information on what works and what does not.

Faculty at the Medical College of Georgia (MCG) were surveyed to find out what elements are important to the development of an effective online …

CCAC Theses and Dissertations

Section 508 of the Rehabilitation Act Amendments of 1998 took effect in 2001 and provides encouragement for universal design and compliance requirements to the federal sector for purchases that are accessible by people with disabilities. A division of General Dynamics Advanced Information Systems (GDAIS) is located in Pittsfield, Massachusetts and provides electronic and information technology solutions to federal customers in the defense, intelligence, and homeland security communities.

The general lack of training is a major factor for low compliance to Section 508. Improving awareness is important at GDAIS in order to increase its federal sales market share, develop new products …

A Model For The Evaluation Of Is/It Investments, Paul M. Tuten

CCAC Theses and Dissertations

Evaluation is a vital--yet challenging--part of IS/IT management and governance. The benefits (or lack therefore) associated with IS/IT investments have been widely debated within academic and industrial communities alike. Investments in information technology may or may not result in desirable outcomes. Yet, organizations must rely on information systems to remain competitive. Effective evaluation serves as one pathway to ensuring success. However, despite a growing multitude of measures and methods, practitioners continue to struggle with this intractable problem.

Responding to the limited success of existing methods, scholars have argued that academicians should first develop a better understanding of the process of …

An Investigation Of The Contributions Of Gender, Shopping Orientation, Online Experience, And Website's Interactive Features To Consumers' Intentions To Engage In Apparel E-Commerce Shopping, Amanda Wynn

CCAC Theses and Dissertations

E-commerce has experienced exponential growth within the last few years. The rapid growth of e-commerce has created a need to improve consumer acceptance and the consumer's intention to engage in e-commerce. Female consumers have yet to embrace e-commerce as readily as male consumers. Differences between male and female consumer shopping behavior were examined.

This study developed and empirically tested a model to predict the consumer's intention to engage in apparel e-commerce shopping based on the constructs of gender, shopping orientation, online experience, and Website's interactive features. Male and female U.S. consumers age 18 and older were surveyed to determine their …

Nonlinear Vortex Dynamics And Transient Domains In Ferromagnetic Disks, Xuemei Cheng, K. S. Buchanan, R. Divan, K. Y. Guslienko, D. J. Keavney

Physics Faculty Research and Scholarship

We report a time-resolved imaging and micromagnetic simulation study of the relaxation dynamics of a magnetic vortex in the nonlinear regime. We use time-resolved photoemission electron microscopy and micromagnetic calculations to examine the emergence of nonlinear vortex dynamics in patterned Ni₈₀Fe₂₀ disks in the limit of long field pulses. We show for core shifts beyond ∼20%–25% of the disk radius, the initial motion is characterized by distortions of the vortex, a transient cross-tie wall state, and instabilities in the core polarization that influence the core trajectories.

Integration Of An Extended Octagonal Ring Transducer And Soil Coulterometer For Identifying Soil Compaction, Santosh K. Pitla, Larry G. Wells, Scott A. Shearer

Biosystems and Agricultural Engineering Faculty Publications

The soil coulterometer is an "on-the-go" electro-mechanical system which collects impedance force data at multiple depths using an oscillating coulter. During the initial testing (summer 2006), only vertical soil impedance force data was collected using a pressure sensor. To improve the performance of the coulterometer, an extended octagonal ring transducer was integrated into the system to collect both the horizontal and vertical impedance forces given by the soil. In the summer of 2007, data was collected using the revised sensor from a typical central Kentucky field setting in a 0.8-ha (2-acre) plot. Four passes were made with the coulterometer. Seventy …

Dynamical Fluctuations In Dense Granular Flows, Emily Gardel, E. Seitaridou, Kevin Facto, E. Keene, K. Hattam, Nalini Easwar, Narayanan Menon

Physics: Faculty Publications

We have made measurements of force and velocity fluctuations in a variety of dense, gravity-driven granular flows under flow conditions close to the threshold of jamming. The measurements reveal a microscopic state that evolves rapidly from entirely collisional to largely frictional, as the system is taken close to jamming. On coarse-grained time scales, some descriptors of the dynamics—such as the probability distribution of force fluctuations, or the mean friction angle—do not reflect this profound change in the micromechanics of the flow. Other quantities, such as the frequency spectrum of force fluctuations, change significantly, developing low-frequency structure in the fluctuations as …

Thyroid Lymphoma As A Cause Of Dysphagia And Dyspnea In A Patient Without Palpable Nodules Or Goiter, Jarrod D. Frizzell, Brandon J. Perkins, R. Scott Morehead

Internal Medicine Faculty Publications

Tumors originating in the neck are well-known causes of progressive dysphagia and dyspnea (including stridor), and thyroid lymphoma is an uncommon example. Physical examination provides an important first step in the evaluation of such complaints, as tumors large enough to produce such symptoms are typically considered to be palpable, if not able to be seen grossly. In this case presentation, the authors describe a nonsubsternal thyroid lymphoma measuring 3 x 4 cm at its largest diameter, producing dysphagia and leading to respiratory emergency, that was entirely nonpalpable to physical exam even after confirmation of its presence by computed tomography.

An Assessment Of Epiphytic Lichens, Lichen Diversity And Environmental Quality In The Semi-Natural Woodlands Of Knocksink Wood Nature Reserve, Enniskerry, County Wicklow, Lenka Mulligan

Masters

This research work adapted and applied a recently developed method for assessing epiphytic lichen species diversity to the Irish semi-natural woodlands of Knocksink Wood Nature Reserve, Enniskerry, County Wicklow. The study focused on the differences that arise in relation to acidophilous oak woodland (Blechno-Quercetum petraeae) versus ash-hazel woodland (Corylo-Fraxinetum). The research also addressed differences in relation to the mixed oak-ash-hazel woodland located in Knocksink Wood and the neighbouring woodland at the Powerscourt Waterfall. The frequency of occurrence of lichen species on a defined portion of tree bark was used as an estimate of diversity and to evaluate the degree of …

How Deregulating Derivatives Led To Disaster, And Why Re-Regulating Them Can Prevent Another, Lynn A. Stout

Cornell Law Faculty Publications

When credit markets froze up in the fall of 2008, many economists pronounced the crisis both inexplicable and unforeseeable. That’s because they were economists, not lawyers.

Lawyers who specialize in financial regulation, and especially the small cadre who specialize in derivatives regulation, understood what went wrong. (Some even predicted it.) That’s because the roots of the catastrophe lay not in changes in the markets, but changes in the law. Perhaps the most important of those changes was the U.S. Congress’s decision to deregulate financial derivatives with the Commodity Futures Modernization Act (CFMA) of 2000.

Prior to 2000, off-exchange derivatives contracts …

A New Generation Of Goals For Technology Education, John M. Ritz

STEMPS Faculty Publications

[Introduction, First paragraph]

To develop meaningful instructional programs for technology education, goals need to be in place to direct the outcomes of curriculum development and teaching. Goals are program terminal outcomes that focus curriculum writers or teachers who structure content for learners. Goals provide direction so content can be delivered for long-term impact to students who study the subject. They go beyond everyday teaching objectives; they are directed at long-term learning and programmatic outcomes.

Discovery Of The Depths, Petros J. Katsioloudis

STEMPS Faculty Publications

Throughout history the oceans have directly or indirectly influenced humans. The importance of knowing how to protect this valuable resource and insure it for future generations is vital. Underwater Vehicles are tools essential for this process, and therefore research and development to perfect these devices is needed. However, the main goal of these devices--to transmit images from places where humans cannot go--remains the same, and their importance to future discoveries remains vital. This article discusses the different types of underwater vehicles and describes an activity wherein students will fabricate an underwater remotely operated vehicle.

Human Persons, Human Rights, And The Distributive Structure Of Global Justice, Robert C. Hockett

Cornell Law Faculty Publications

It is common for economically oriented transnational legal theorists to think and communicate mainly in maximizing terms. It is less common for them to notice that each time we speak explicitly of maximizing one thing, we speak implicitly of distributing another thing and equalizing yet another thing. Moreover, we effectively define ourselves and our fellow humans by reference to that which we equalize. For it is in virtue of the latter that our global welfare formulations treat us as "counting" for purposes of globally aggregating and maximizing.

To analyze maximization language on the one hand, and equalization and identification language …

Role Of Assigned Team Goals In The Relationship Between Individual Difference Factors And Self-Set Goals In A Pre-Team Context, Anupama Narayan

Browse all Theses and Dissertations

The purpose of the present study was to examine the effects of individual difference factors, i.e., core self evaluations, cognitive ability, and task specific self-efficacy, on self-set goals and whether those effects were moderated by an assigned team goal in a pre-team context. It was hypothesized that the relationship between individual difference factors and self-set goals for potential team members would be differentially affected by the difficulty of the assigned team goal. I assessed these relationships for individual performance and individual satisfaction. In addition, I examined whether gender, task type, and team composition interacted in their effects on self-set goals. …

A System For Incorporating Time-Based Event-Condition-Action Rules Into Business Databases, Christina Marie Steidle

Browse all Theses and Dissertations

Human beings handle time-based events continuously; however the passage of time does not play an active part in most business systems because they are typically driven by interaction from human users or other systems. In order to take an action based upon the passage of time it is necessary to build a framework which will monitor the progression of time and a way to define what events the system should be waiting for. This thesis describes such a system, and shows that the system performs as specified. With this system business users are able to build event-condition-action rules using a …

International Law In Domestic Courts: A Conflict Of Laws Approach, Karen Knop, Ralf Michaels, Annelise Riles

Cornell Law Faculty Publications

The relationship between international law and domestic law is rarely understood as a conflict of laws. Understanding it in this way opens up a parallel with the field of conflict of laws: the field for which the relationship between legal systems, especially the role of another system's jurisdiction, laws, and judgments vis-à-vis the domestic legal system, are exactly the bread-and-butter issues. We argue for such an approach to international law in domestic courts: an approach that we elaborate as "theory through technique."

In our view, conflicts should be seen broadly as the discipline that developed to deal with conflicts between …
