The Effects Of Teacher Ideology On Student Performance As Related To Poverty And Ethnicity, Jessica Webb Jan 2010

The Effects Of Teacher Ideology On Student Performance As Related To Poverty And Ethnicity, Jessica Webb

Electronic Theses and Dissertations

This study was conducted to explore the impact of teacher ideology on student performance. A definition of teacher ideology was drawn from the pupil control ideology, PCI, created by Willower, Eidell and Hoy (1967). Research concerned with teacher ideology has suggested that there is a definite difference between the custodial ideology and the humanistic ideology (Gaffney, 1997). In particular, the custodial teacher views rules and regulations as a priority, while the humanistic teacher views the student as the priority. Factors which influenced student achievement, such as socioeconomic status, ethnicity, and behavior in relation to how teacher ideology affects student performance …

A Survey Of Transition Strategies To Improve The Performance Of Chord In The Face Of Rapidly Changing Ip Addresses, Timothy Ecklund Jan 2010

A Survey Of Transition Strategies To Improve The Performance Of Chord In The Face Of Rapidly Changing Ip Addresses, Timothy Ecklund

Theses

Mobile wi-fi enabled devices are becoming less expensive and more common all the time. The field is ripe for DHTs like Chord. Given the highly scalable nature of DHTs, the ability to efficiently tap the storage resources of so many devices is very attractive. Unfortunately DHTs have been having a difficult time finding a foothold on mobile devices due to poor performance, both in terms of network overhead and lookup failure. Much of the research that has been done attributes this poor performance to the extra hops packets must make due to the mismatch between the physical topology and the …


From Medical Images To Individualized Cardiac Mechanics: A Physiome Approach, Chun Wong Jan 2010

From Medical Images To Individualized Cardiac Mechanics: A Physiome Approach, Chun Wong

Theses

Cardiac mechanics is a branch of science that deals with forces, kinematics, and material properties of the heart, which is valuable for clinical applications and physiological studies. Although anatomical and biomechanical experiments are necessary to provide the fundamental knowledge of cardiac mechanics, the invasive nature of the procedures limits their further applicability. In consequence, noninvasive alternatives are required, and cardiac images provide an excellent source of subject-specific and in vivo information. Noninvasive and individualized cardiac mechanical studies can be achieved through coupling general physiological models derived from invasive experiments with subject-specific information extracted from medical images. Nevertheless, as data extracted …


Patent Pools, Rand Commitments, And The Problematics Of Price Discrimination, Daniel A. Crane Jan 2010

Patent Pools, Rand Commitments, And The Problematics Of Price Discrimination, Daniel A. Crane

Book Chapters

The social welfare problematics of patent pooling by competitors are well known. Competitor patent pooling has the potential to create powerful efficiencies by eliminating holdout problems and blocking positions and reducing transactions costs from licensing negotiations. At the same time, competitors can use patent pools to cartelize in a variety of ways, for example by fixing prices, entrenching patents of dubious validity, and discouraging rivalry for innovation. Determining legal norms capable of capturing the efficiencies without enabling cartels has not proven easy.

Perhaps because of the practical difficulty of separating pro-competitive from anticompetitive pools, antitrust scrutiny has swung from extreme …


Information Theoretic Approach For Assessing Image Fidelity In Photon-Counting Arrays, Srikanth R. Narravula, Majeed M. Hayat, Bahram Javidi Jan 2010

Information Theoretic Approach For Assessing Image Fidelity In Photon-Counting Arrays, Srikanth R. Narravula, Majeed M. Hayat, Bahram Javidi

Electrical and Computer Engineering Faculty Research and Publications

The method of photon-counting integral imaging has been introduced recently for three-dimensional object sensing, visualization, recognition and classification of scenes under photon-starved conditions. This paper presents an information-theoretic model for the photon-counting imaging (PCI) method, thereby providing a rigorous foundation for the merits of PCI in terms of image fidelity. This, in turn, can facilitate our understanding of the demonstrated success of photon-counting integral imaging in compressive imaging and classification. The mutual information between the source and photon-counted images is derived in a Markov random field setting and normalized by the source-image’s entropy, yielding a fidelity metric that is between …


Consciousness And Society: Societal Aspects And Implications Of Transpersonal Psychology, Harry T. Hunt Jan 2010

Consciousness And Society: Societal Aspects And Implications Of Transpersonal Psychology, Harry T. Hunt

International Journal of Transpersonal Studies

Although transpersonal psychologies of self realization emphasize individual

development, earlier shamanic traditions also showed a central societal aspect and group based

consciousness. Indeed, many have understood the transpersonal movement as developing

towards an abstract globalized neo-shamanism. That altered states of consciousness, whether

as integrative realizations of the numinous or as dissociative “hypnoid” states, could be felt

and shared collectively was a familiar concept to the first generation of sociologists, who saw

all consciousness as social and dialogic in form. Durkheim, in particular, foresaw a globalized

spirituality of the future, his “cult of man,” in which modern individuation would progress

to …


Relational Spirituality, Part 2 The Belief In Others As A Hindrance To Enlightenment: Narcissism And The Denigration Of Relationship Within Transpersonal Psychology And The New Age, Gregg Lahood Jan 2010

Relational Spirituality, Part 2 The Belief In Others As A Hindrance To Enlightenment: Narcissism And The Denigration Of Relationship Within Transpersonal Psychology And The New Age, Gregg Lahood

International Journal of Transpersonal Studies

The aim of this paper is to tease out from the New Age religion and religious transpersonal psychology a more relational spirituality. Humanistic and transpersonal psychologies were important forces in the emergence of the social phenomenon of the New Age. New Age transpersonalism leans toward a restrictive non-relational spirituality because of its historical affirmation of individualism and transcendence. Relational spirituality, which is central to the emerging participatory paradigm, swims against strong and popular currents in New Age transpersonal thinking which tend to see spirituality as an individual, personal, inner pursuit, often into Eastern/Oriental nondualism. Whatever the merits of impersonal Advaita …


Transpersonal And Other Models Of Spiritual Development, Harris Friedman, Stanley Krippner, Linda Riebel, Chad Johnson Jan 2010

Transpersonal And Other Models Of Spiritual Development, Harris Friedman, Stanley Krippner, Linda Riebel, Chad Johnson

International Journal of Transpersonal Studies

This chapter focuses on exploring various models of spiritual development. It first addresses

philosophical dilemmas underpinning the concept of spiritual development by questioning

whether these can be addressed without metaphysical assumptions embedded in religious

worldviews and thus understood in any consensual way across different historical and

cultural contexts. Traditional models of spiritual development are then reviewed, drawing

from indigenous, Eastern, and Western cultures. Integrative-philosophical and scientific

models, including those from the psychology of religion, transpersonal psychology, and

neurobiology, are then presented. The chapter concludes by noting the complexities involved

in understanding spiritual development accompanied by suggestions on future directions

for …

In The Trenches Of Florida’S War On Gangs: A Framework For Prosecuting Florida’S Anti-Gang Sentence Enhancement Provision, Rodrigo M. Caruço Jan 2010

In The Trenches Of Florida’S War On Gangs: A Framework For Prosecuting Florida’S Anti-Gang Sentence Enhancement Provision, Rodrigo M. Caruço

Barry Law Review

This article discusses how the State of Florida prosecutes under the new sentence enhancement provision of Florida’s anti-gang statute. Part I discusses the general history of the provision. Part II analyzes different state approaches to the enhancement provision. Finally, Part III concludes the article with two recommendations. First, a statutory response that provides all courts in the State with clear direction to implement this provision. Second, a judicial approach for Florida courts to consistently implement a provision that is essential to Florida’s war on criminal gangs.

Apparent Seasonal Cycle In Isotopic Discrimination Of Carbon In The Atmosphere And Biosphere Due To Vapor Pressure Deficit, Ashley P. Ballantyne, J. B. Miller, P. P. Tans Jan 2010

Apparent Seasonal Cycle In Isotopic Discrimination Of Carbon In The Atmosphere And Biosphere Due To Vapor Pressure Deficit, Ashley P. Ballantyne, J. B. Miller, P. P. Tans

Ecosystem and Conservation Sciences Faculty Publications

We explore seasonal variability in isotopic fractionation by analyzing observational data from the atmosphere and the biosphere, as well as simulated data from a global model. Using simulated values of atmospheric CO2 and its carbon isotopic composition, we evaluated different methods for specifying background concentrations when calculating the isotopic signature of source CO2 (δs) to the atmosphere. Based on this evaluation, we determined that free troposphere measurements should be used when available as a background reference when calculating δs from boundary layer observations. We then estimate the seasonal distribution of δs from monthly …

Building A Mechanistic Understanding Of Predation With Gps-Based Movement Data, Evelyn Merrill, Ha˚Kan Sand, Barbara Zimmermann, Heather Mcphee, Nathan Webb, Mark Hebblewhite, Peter Wabakken, Jacqueline L. Frair

Biological Sciences Faculty Publications

Quantifying kill rates and sources of variation in kill rates remains an important challenge in linking predators to their prey. We address current approaches to using global positioning system (GPS)-based movement data for quantifying key predation components of large carnivores. We review approaches to identify kill sites from GPS movement data as a means to estimate kill rates and address advantages of using GPS-based data over past approaches. Despite considerable progress, modelling the probability that a cluster of GPS points is a kill site is no substitute for field visits, but can guide our field efforts. Once kill sites are …

The Weak Protection Of Strong Encryption: Passwords, Privacy, And Fifth Amendment Privilege, Nathan K. Mcgregor Jan 2010

The Weak Protection Of Strong Encryption: Passwords, Privacy, And Fifth Amendment Privilege, Nathan K. Mcgregor

Vanderbilt Journal of Entertainment & Technology Law

While the constitutional protection afforded private papers has waxed and waned for more than a century, the Supreme Court has greatly restricted the Fifth Amendment privilege against self-incrimination--at least as applied to voluntarily prepared documents. Specifically, where the government knows of the existence and location of subpoenaed documents, the Fifth Amendment guarantee will not justify a failure to produce them, unless the act of production would itself incriminate the defendant. However, the Self-Incrimination Clause still precludes the compelled creation of documents that are both incriminating and testimonial.

The "private papers" doctrine has remained relatively stable for approximately thirty years now, …


Reinforcement Learning Based Strategies For Adaptive Wireless Sensor Network Management, Kunalbhai Shah Jan 2010

Reinforcement Learning Based Strategies For Adaptive Wireless Sensor Network Management, Kunalbhai Shah

Computer Science and Engineering Dissertations - Archive

In wireless sensor networks (WSN), resource-constrained nodes are expected to operate in highly dynamic and often unattended environments. WSN applications need to cope with such dynamicity and uncertainty intrinsic in sensor networks, while simultaneously trying to achieve efficient resource utilization. A middleware framework with support for autonomous, adaptive and distributed sensor management, can simplify development of such WSN applications. We present a reinforcement learning based WSN middleware framework to enable autonomous and adaptive applications with support for efficient resource management. The uniqueness of our framework lies in using a bottom-up approach where each sensor node is responsible for its resource …


Fluvial Architecture And Geometry Of The Mungaroo Formation Of Rankin Trend On The Northwest Shelf Of Australia, Scott Bradley Stoner Jan 2010

Fluvial Architecture And Geometry Of The Mungaroo Formation Of Rankin Trend On The Northwest Shelf Of Australia, Scott Bradley Stoner

Earth & Environmental Sciences Theses - Archive

The Northwest Shelf of Australia contains many producing world class gas reservoirs with large areas remaining unexplored. The fluvio-deltaic Mungaroo Formation of Rankin Trend on the Northwest Shelf is the site of many producing fields on the Northwest Shelf and data collected from these sites is invaluable in understanding the architecture and geometry of the fluvial strata that house these reservoirs. The Mungaroo Formation contains alternating sections of low accommodation amalgamated sand bodies, and high accommodation shale prone sections that record architecturally complex floodplain deposits. The study sections were broken down into eight architectural elements; thalweg fill, unit bar, abandonment …


Field-Induced Quantum Phase Transitions In The Spin-1/2 Triangular-Lattice Antiferromagnet Cs2cubr4, Nathanael Alexander Fortune, Scott T. Hannahs, Y. Takano, Y. Yoshida, T. Sherline, A. A. Wilson-Muenchow, T. Ono, H. Tanaka Jan 2010

Field-Induced Quantum Phase Transitions In The Spin-1/2 Triangular-Lattice Antiferromagnet Cs2cubr4, Nathanael Alexander Fortune, Scott T. Hannahs, Y. Takano, Y. Yoshida, T. Sherline, A. A. Wilson-Muenchow, T. Ono, H. Tanaka

Physics: Faculty Publications

In classical magnetic spin systems, geometric frustration leads to a large number of states of identical energy. We report here evidence from magnetocaloric and related measurements that in Cs2CuBr4 — a geometrically frustrated Heisenberg S= 1/2 triangular antiferromagnet — quantum fluctuations stabilize a series of gapped collinear spin states bounded by first-order transitions at simple increasing fractions of the saturation magnetization for fields directed along the c axis. Only the first of these quantum phase transitions has been theoretically predicted, suggesting that quantum effects continue to dominate at fields much higher than previously considered.
