The Organizational Action Research Model, Morton Elfenbein, Stephen M. Brown, Kim H. Knight

WCBT Faculty Publications

This chapter proposes a paradigm, which empowers practitioners to practice research to meet their needs and to advance the profession to which they belong. It proposes the integration of practitioner and researcher role as an alternative to the fragmented model that currently exists. In doing so, it draws much from the past tradition of the action researchers as well as the science approach espoused by others. In this way, the needs of individual managers to evaluate their espoused theories and their theories-in-use can be undertaken so that their organizations can function more realistically and can respond more effectively to the …

The Young Women's Leadership School: A Viable Alternative To Traditional Coeducational Public Schools, Erin A. Mcgrath

Cardozo Journal of Equal Rights & Social Justice

The note argues that single-sex education is a beneficial and constitutional alternative to traditional coeducational programs, using the Young Women's Leadership School as a prime example. It contends that such schools address past discrimination and provide tailored educational environments that enhance academic performance and self-esteem, particularly for underprivileged girls. The analysis emphasizes that single-sex education can meet legal standards under Title IX and Equal Protection scrutiny, as demonstrated by the Leadership School's compliance with regulatory requirements and its focus on remedying historical inequities.

Characterization Of Hydrogen Permeation Through Zinc-Nickel Alloys Under Corroding Conditions: Mathematical Model And Experimental Study, M. Ramasubramanian, Branko N. Popov, Ralph E. White

Faculty Publications

A mathematical model was developed for the characterization of hydrogen permeation into metals and alloys under corroding conditions. The model requires a knowledge of the corrosion rate of the given metal or alloy in solutions of various H⁺ concentrations. It provides quantitative values of rate constants of the hydrogen discharge, recombination, and adsorption reactions. This model can serve as a diagnostic criterion for determining the effectiveness of various metals and alloys as hydrogen permeation inhibitors and can be used for evaluation of hydrogen entry inhibition efficiency. Experiments were carried out to study the effectiveness of thin layers of electrodeposited …

Theoretical Analysis Of Metal Hydride Electrodes: Studies On Equilibrium Potential And Exchange Current Density, Bala S. Haran, Branko N. Popov, Ralph E. White

Faculty Publications

A theoretical model for the metal hydride electrode has been developed assuming that hydrogen diffusion in the alloy and charge-transfer at the surface control the discharge process. Theoretical equations for the dependence of equilibrium potential and exchange current density on the surface hydrogen concentration have been derived. These parameters have been used to correlate experimental data with the theoretical electrode discharge model. Analysis of both the experimental and theoretical discharge curves reveals a potential plateau determined by the magnitude of the interactions between the hydrogen in the alloy and the unhydrided metal. Neglecting these hydrogen-metal site interactions results in simulations …

The Role Of Oxygen At The Second Discharge Plateau Of Nickel Hydroxide, Sathya Motupally, Mukul Jain, Venkat Srinivasan, John W. Weidner

Faculty Publications

It was shown that the appearance of a secondary discharge plateau approximately 400 mV below the primary plateau can result from the reduction of oxygen. During the galvanostatic discharge of planar nickel-hydroxide films at room temperature and in 3 weight percent KOH solutions, the second discharge plateau was observed only in the presence of dissolved oxygen in the electrolyte. When the solution was deoxygenated, no residual capacity could be extracted from the films even at low discharge rates or from overcharged films. In addition, the duration of the second plateau is inversely proportional to the square of the discharge current, …

Steady-State Modeling Of A Parallel-Plate Electrochemical Fluorination Reactor, Kamal Jha, Gerald L. Bauer, John W. Weidner

Faculty Publications

A steady-state mathematical model of a parallel-plate reactor was developed for studying the electrochemical fluorination of organic compounds dissolved in anhydrous hydrogen fluoride. The model incorporates two-phase flow with differential material, energy, and pressure balances. Profiles of temperature, pressure, vapor volume fraction, and current density in the reactor are presented at two inlet temperatures to provide insight into the operation of the reactor. The effects of the inlet temperature, feed flow rate, and cell current on the cell pack voltage and current efficiency of the reactor are presented to determine problematic operating regions for the reactor. Optimum operating currents based …

The Effect Of Particle Size On The Discharge Performance Of A Nickel-Metal Hydride Cell, Jussi M. Heikonen, Harry J. Ploehn, Ralph E. White

Faculty Publications

We investigate the effect of particle size on the discharge performance of a nickel-metal hydride cell with a mathematical model. Electrodes with uniform as well as with nonuniform particle sizes are studied. With uniform particle size, the dependence of the particle-to-particle resistance on the particle size is taken into account. The optimal particle size depends on the discharge rate. Moreover, we show that under certain conditions it is advantageous to use a nonuniform particle size. In general, the higher the discharge current density, the more the particle size affects the electrode performance.

Π-Systems As Lithium/Hydrogen Bond Acceptors: Some Theoretical Observations, Salai Cheettu Ammal, P. Venuvanalingam

Faculty Publications

Ab initio calculations at the Hartree–Fock and correlated levels and density functional theory calculations have been performed with 6-31++G(d,p) and 6-311++G(d,p)basis sets on LiF and HF complexes of benzene, ethylene, and acetylene. Complex binding energies have been corrected for basis set superposition error, and zero point energy corrections have been done on Hartree–Fock binding energies. Computed results indicate that the complexes exist in different conformations and among them those with π-lithium and π-hydrogen bonds are the most stable. π-lithium bonds are stronger than π-hydrogen bonds. The computed binding energies and geometry of HF complexes correlate well with the available experimental …

Ab Initio And Dft Investigations Of Lithium/Hydrogen Bonded Complexes Of Trimethylamine, Dimethyl Ether And Dimethyl Sulfide, Salai Cheettu Ammal, P. Venuvanalingam

Faculty Publications

Ab initio and DFT computations have been carried out on LiF and HF complexes of a set of n-donors viz. trimethylamine, dimethyl ether and dimethyl sulfide with a 6-31++G(d,p) basis set. The effect of correlation has been included with MP2, MP4 and DFT calculations. NBO analyses of the wavefunctions have been performed to examine the intermolecular interaction at the orbital level. Calculations reveal that these donors form strong n→σ* complexes and computed binding energies of the (CH₃)₂O···HF complex agree very well with the experimental binding energies from IR spectroscopy. LiF forms stronger complexes than HF, …

Young Children's Understanding Of Design In The Technology Process, Jean E. O'Sullivan

Theses : Honours

This study explored the development of children's thinking when social constructivist principles of learning were implemented through technological experiences. The study monitored the development of children's understanding of “design" through project work, using classroom based action research. In addition to investigating children's understandings, the study explored the use of technology in early childhood curriculum to develop the skills said to be required in the next millennium. The study found that five year old children are capable of "designing" and that technology is an effective vehicle for developing socially, contextually and culturally appropriate learning experiences.

A Comparison Of Highly Efficient Iterative Linear Solvers, Akbar Chowdhury

Theses

A number of iterative techniques have recently been developed which are extremely efficient at solving systems of linear equations. Of these methods probably the most recognized is the Conjugate Gradient Method (CG). This is an extremely efficient solver and has been used successfully for a number of years now. A newer method proposed initially by Davidson [1] is studied in this paper. This method has proven itself in terms of efficiency by solving the same system (of order 2000) that was solved by the CG method. It converged in approximately 40 iterations, taking less than five minutes to do so[5], …

A Comparison Of The Viability Of Thistle Weevils From Fire Ant Suppressed Site To Weevils From A Site Where Fire Ants Were Not Suppressed, Mary T. Hodge

Theses and Dissertations

The thistle weevil, Rhinocyllus conicus, was introduced to the United States as an agent of biological control for another non-native species, the musk thistle, Carduus nutans. Musk thistle are noxious weeds of pastures which reduce forage for grazing livestock. A high weevil population is necessary to achieve control of musk thistle. The study site is situated at the southernmost boundary of the invading thistle, the thistle weevil, and another invasive non-native, the red imported fire ant, Solenopsis invicta. The research compared the viability of R. conicus from a S. invicta suppressed site to the viability from a …

Composition And Environmental Assessment Of Soils From United Arab Emirates, Torfa Alsheba Khames Alsheriani

Theses

The study focuses on the mineral and chemical composition, the textural characters and environmental assessment of some soils from the UAE. About forty soil samples were collected from AI Ain District and the Eastern Mountain District. Soils in AI Ain and its suburb are strongly influenced by the aeolian sedimentation, while those of the Eastern Mountain are formed in narrow valleys strikingly close to ophiolitic hinterland.

The studied soils· are remarkably impoverished in clay size fraction and clay minerals as well. This is due to the impeded chemical weathering under the prevailing arid climate. Corroborative techniques including X-ray diffraction, infrared …

An Upper Limit On The Τ Neutrino Mass From Three- And Five-Prong Tau Decays, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

A bound on the tau neutrino mass is established using the data collected from 1991 to 1995 at s√≃mZ with the ALEPH detector. Two separate limits are derived by fitting the distribution of visible energy vs invariant mass in τ−→2π−π+ντ and τ−→3π−2π+(π0)ντ decays. The two results are combined to obtain a 95% confidence level upper limit of 18.2 MeV/c2 on the mass of the tau neutrino.

Observation Of Doubly-Charmed B Decays At Lep, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

A search for doubly-charmed B decays with both charmed mesons reconstructed is performed, using about 3.8 million hadronic Z decays recorded with the ALEPH detector at LEP. A clear signal is observed in the channels B→DsD¯(X)B→DsD¯(X) and B→DD¯(X)B→DD¯(X) (where D can be either a D00, a D++ or a D∗+∗+), providing the first direct evidence for doubly-charmed B decays involving no DsDs production. Evidence for associated K0SKS0 and K±K± production in the decays B→DD¯(X)B→DD¯(X) is also presented and some candidates for completely reconstructed decays B→DsD¯(nπ)B→DsD¯(nπ), B→DD¯K0SB→DD¯KS0 and B→DD¯K±B→DD¯K± are observed. Furthermore, candidates for the two-body Cabibbo suppressed decays B0→D∗−D∗+B0→D∗−D∗+ and …

Searches For Charginos And Neutralinos In E+E- Collisions At √S = 161 And 172 Gev, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

The data recorded by the ALEPH detector at centre-of-mass energies of 161, 170, and 172 GeV are analysed for signals of chargino and neutralino production. No evidence of a signal is found, although candidate events consistent with the expectations from Standard Model processes are observed. Limits at 95% C.L. on the production cross sections are derived and bounds on the parameters of the Minimal Supersymmetric Standard Model are set. The lower limit on the mass of the lightest ch is 85.5 GeV/c2GeV/c2 for gaugino-like charginos (μ=−500GeV/c2μ=−500GeV/c2), and 85.0 GeV/c2GeV/c2 for Higgsino-like charginos (M2=500GeV/c2M2=500GeV/c2), for heavy sneutrinos (Mν~≥200GeV/c2Mν~≥200GeV/c2) and tanβ=2–√tan⁡β=2.

The Desegregation Of A Historically Black High School In Jacksonville, Florida, Judith Bockel Poppell

UNF Graduate Theses and Dissertations

This historical study examines the desegregation of a historically African- American high school during the period between 1965-1975. The Mims v. The Duval County School Board (1971) decision brought about radical changes in the operation of the Duval County Public Schools. The mass transfer of teachers and reassignment of students as a result of the federal judge's order in this case resulted in a school system that was dramatically different from the one that previously existed. The author seeks to determine why the desegregation of William Raines High School was short-lived and questions the continued effort of the school system …

Courting Serendipity: Constructivist Theory And Classroom Practice, Marilyn Duckworth Jensen

UNF Graduate Theses and Dissertations

This dissertation is a cross-case study and analysis of four teachers in a school involved in two reform initiatives which promote constructivist approaches to teaching and learning. The study describes the teachers' understandings of the learning theory and their interpretations of it in their classroom practice. The study found that three of the four teachers were practicing in ways consistent with constructivism while one was not because her need for control took precedence. The study found that although teachers are very aware of their students as individuals with different ways of learning and constructing an understanding, they are not much …

A New Options Theory For Risk Multipliers Of Attorney's Fees In Federal Civil Rights Litigation, Peter H. Huang

Publications

Given the importance of private enforcement of federal civil rights laws, Congress and the courts have attempted to encourage plaintiffs' attorneys to accept meritorious civil rights cases through fee shifting and risk multipliers. Recently, however, the Supreme Court has essentially prohibited the use of risk multipliers, thus undercompensating attorneys for the risk of losing civil rights actions and discouraging the filing of such cases. In this Article, Professor Huang develops a new options-based theory of calculating attorney's fees. Professor Huang argues that a lawsuit consists of a sequence of options to continue with the case rather than a once-and-for-all irreversible …
