The Defense Of Traditional Marriage, George W. Dent

Faculty Publications

This article reviews the possible justifications for legal recognition of marriage and finds some, such as encouraging stable, loving relationships, unpersuasive. However, other rationales-including protecting children, socializing adults, and promoting individual happiness-are valid, and these rationales apply only to traditional marriages. Accordingly, society has strong reasons to favor traditional marriage and to deny such treatment to the unmarried and to homosexual, endogamous and bestial relationships.

Bastardy And The Statute Of Wills: Interpreting A Sixteenth-Century Statute With Cases And Readings, M C. Mirow

Faculty Publications

The Statute of Wills of 1540 created a tax loophole for transfers of property to illegitimate children. Assessments for wardships that would normally be imposed on certain transfers of land to children could be effectively avoided by establishing that the donee was illegitimate, and therefore a stranger to the donor for the purposes of the statute. English lawyers in the sixteenth and seventeenth centuries educated their colleagues about this newly available loophole. In the inns of court, lawyers discussed the statutory provisions and recent revenue cases from the Court of Wards. This article sets out the loophole, examines how the …

Dam Nation: A Geographic Census Of American Dams And Their Large-Scale Hydrologic Impacts, William L. Graf

Faculty Publications

Newly available data indicate that darns fragment the fluvial system of the continental United States and that their impact on river discharge is several times greater than impacts deemed likely as a result of global climate change. The 75,000 dams in the continental United States are capable of storing a volume of water almost equaling one year's mean runoff, but there is considerable geographic variation in potential surface water impacts. In some western mountain and plains regions, darns can store more than 3 year's runoff, while in the Northeast and Northwest, storage is as little as 25% of the annual …

The understanding of valuable catalytic and adsorptive properties of heterogeneous catalysts at atomic and electronic levels is essential for the design of novel catalysts. Computer simulation studies can significantly contribute to provide a rational interpretation of the observed experimental results and suggest modification of new catalysts. Our recent work on the application of integrated computer simulation methods to investigate the structure and catalytic properties of solid surfaces including zeolites, transition metals and their oxides have been reviewed in this paper. We have emphasized the effectivity and applicability of integrated computer simulation system to solve the problems in a variety of …

Material Balance Modification In One-Dimensional Modeling Of Porous Electrodes, Mukul Jain, John W. Weidner

Faculty Publications

The material balance used previously in one-dimensional mathematical models of porous electrodes is invalid when there is a non-zero volume change associated with the reaction. It is shown here how the material balance should be modified either to account for a loss in volume, or to account for an inflow of electrolyte from the header into the active pores. A one-dimensional mathematical model is used to illustrate the effect of this correction on the prediction of the delivered capacity and the electrolyte concentration in a lithium/thionyl chloride primary battery.

Correlation Of Double-Layer Capacitance With The Pore Structure Of Sol-Gel Derived Carbon Xerogels, Chuan Lin, James A. Ritter, Branko N. Popov

Faculty Publications

Nine different sol-gel derived carbon xerogels were prepared with different pore structures by varying the carbonization temperature (in flowing N₂) and activation time (in 5% CO₂ in N₂). For each of these carbon xerogels, mesopore and micropore size distributions and cumulative surface areas were extracted from a density functional theory analysis. Increasing the carbonization temperature caused a decrease in the number of micropores in the 6 Å range but had little effect on the mesopore size distribution and thus mesopore cumulative surface area. Increasing the CO₂ activation time caused an increase in the number …

A Mathematical Model Of An Electrochemical Capacitor With Double-Layer And Faradaic Processes, Chuan Lin, James A. Ritter, Branko N. Popov, Ralph E. White

Faculty Publications

A mathematical model of an electrochemical capacitor with hydrous ruthenium oxide (RuO₂·xH₂O) electrodes including both double-layer and surface faradaic processes is developed to predict the behavior of the capacitor under conditions of galvanostatic charge and discharge. The effect of RuO₂·xH₂O particle size is studied and shows that the smaller the particles the better the performance because of the increased surface area per unit volume or mass. The model also predicts that the faradaic process increases significantly the energy per unit volume of the capacitor for power densities of …

Development Of Carbon-Metal Oxide Supercapacitors From Sol-Gel Derived Carbon-Ruthenium Xerogels, Chuan Lin, James A. Ritter, Branko N. Popov

Faculty Publications

Sol-gel derived high surface area carbon-ruthenium xerogels were prepared from carbonized resorcinol-formaldehyde resins containing an electrochemically active form of ruthenium oxide. The electrochemical capacitance of these materials increased with an increase in the ruthenium content indicating the presence of pseudocapacitance associated with the ruthenium oxide undergoing reversible faradaic redox reactions. A specific capacitance of 256 F/g (single electrode) was obtained from a carbon xerogel containing 14 wt % Ru, which corresponded to more than 50% utilization of the ruthenium. The double layer accounted for 40% of this capacitance. This material was also electrochemically stable, showing no change in a cyclic …

A Mathematical Model For Electroless Copper Deposition On Planar Substrates, M. Ramasubramanian, Branko N. Popov, Ralph E. White, K. S. Chen

Faculty Publications

A mathematical model for the electroless deposition of copper on a planar electrode is presented and used to make time-dependent predictions on the various quantities in the system. The model takes into account mass transport by diffusion and migration, Butler-Volmer kinetics at the electrode surface, and mixed potential theory. A finite difference approach is used to solve the equations, and the resultant model is used to predict the concentration profiles, potential response, and plating rate as a function of time and concentration of various reactive components.

Mathematical Modeling Of Electrochemical Capacitors, Venkat Srinivasan, John W. Weidner

Faculty Publications

Analytic solutions to the mathematical model of an electrochemical capacitor (EC) are used to study cell performance under two types of operating conditions: (i) constant current and (ii) electrochemical impedance spectroscopy. The analytic solution under constant-current operation is used to investigate the relative importance of ionic resistance in the separator, and ionic and electronic resistances in the porous electrode in the design and operation of an EC. Model results are presented that show the trade-off between energy and power density, as the physical properties of the cell components are varied (e.g., electrode thickness). The analytic solution …

Micropolarizer Array For Infrared Imaging Polarimetry, M. W. Jones, Gregory P. Nordin, P. C. Deguzman, J. T. Meier

Each micropolarizer consists of a 475-nm-period Mo wire grid in a 16 μm × 16 μm aperture. Interference lithography is used to generate the small grating features through an etch mask layer. Arrays of 256 × 256 micropolarizers at three distinct angular orientations have been fabricated that permit the measurement of the first three Stokes vector components in each pixel of an imaging polarimeter. An imaging system composed of a micropolarizer array integrated directly onto a focal plane array has been assembled, and …

A Cloud-Removal Algorithm For Ssm/I Data, David G. Long, Douglas L. Daum, Quinn P. Remund

Faculty Publications

Microwave radiometers, while traditionally utilized in atmospheric and oceanic studies, can also be used in land surface applications. However, the problem of undesirable atmospheric effects caused by clouds and precipitation must be addressed. In this paper, temporal composite surface brightness images are generated from special sensor microwave/imager (SSM/I) data with the aid of new algorithms to eliminate small-scale distortion caused by clouds or precipitation. Mean, second-highest value, modified maximum average (MMA), and hybrid compositing algorithms are compared. The effectiveness of each algorithm is illustrated through simulation and real data distribution analysis. The results show that the second-highest value algorithm is …

Performance Surface Prediction For Wan-Based Clusters, Mark J. Clement, J. Kelly Flanagan, Glenn M. Judd, Bryan S. Morse, Joy L. Peterson

Faculty Publications

The last five years have been a period of exponential growth in the number of machines connected to the Internet and the speed at which these machines communicate. The infrastructure is now in place to consider a nationwide cluster of workstations as a viable parallel processing platform. In order to achieve acceptable performance on this kind of a machine, performance prediction tools must provide information on where to place computational objects. Incorrect object placement can result in poor performance and congestion in the network. This research develops a new paradigm for predicting performance in the Wide Area Network (WAN) based …

More Precious Than Gold: The Journey To And Through Zion In 1849-50, Fred E. Woods

Faculty Publications

The California gold rush, the first international gold rush in history, turned the world upside down, reaching its zenith in the years 1849-50. As a result of the rush during these two climactic years, the population swelled our nation's Pacific coast, entitling California to receive statehood in the fall of 1850. During these catalytic years, Latter-day Saints were journeying to the American West for a different kind of treasure. They gathered from afar to their Mormon mecca nestled in the Salt Lake Valley to fulfill their dreams of establishing Zion. Yet the California gold rush had a significant impact on …

Evaluating Therapy Outcome At A University Counseling Center Wit The College Adjustment Scales, Timothy B. Smith, Mark A. Nafziger, Gwenna C. Couillard

Faculty Publications

To assess the effectiveness of time-limited therapy in a university counseling center, 333 clients' pre-counseling and post-sixth session College Adjustment Scales (CAS) scores were compared. Statistical significant decreases in reported symptomatology were found on all CAS scales. Analyses of CAS data for students who were notably distressed prior to receiving counseling also yielded statistically significant differences, with effect sizes revealing moderate to large decreases in symptomatology. Further replicative work is recommended to document the impact and effectiveness of counseling center services.

Health And Educational Outcomes Of Children Who Experienced Severe Neonatal Medical Complications, Timothy B. Smith, Glenna C. Boyce, Glendon Castro

Faculty Publications

To determine the long-term developmental and educational outcomes of a sample of low birthweight infants with intraventricular hemorrhage (IVH), developmental assessments and interviews were conducted eight years after the initiation of an early intervention project. At the time of the follow-up, 62% of children were experiencing some developmental or behavior problems, with visual impairments, cerebral palsy, and attention deficits occurring most frequently. Grade of IVH and the number of days spent in the neonatal intensive care unit were the best predictors of later developmental delays. The sample also scored below average on school achievement; approximately 30% of those in school …

Price And Non-Price Influences On Water Conservation: An Econometric Model Of Aggregate Demand Under Nonlinear Budget Constraints, Leonardo Corral, Anthony C. Fisher, Nile W. Hatch

Faculty Publications

This paper develops a model of residential water demand under a nonlinear budget constraint. The theoretical model for an individual consumer is adapted to yield an aggregate model that preserves the structure of the individual demand function, and that can be used with aggregate (water district level) data. The model is used to study the influence of pricing and non-price conservation programs on consumption and conservation behavior in three water districts in the San Francisco Bay Area, over a 10-year period that includes both drought and normal years. Empirical results show that pricing can be effective in reducing water consumption, …

A Rejoinder To Kenworthy-U'Ren Enlarging The Tent Of Service-Learning, Paul C. Godfrey

Faculty Publications

The Old Testament prophet/poet Isaiah speaks of the eventual redemption of the children of Abraham and uses a powerful metaphor to invite his followers to action: "Enlarge thy tent, and let them stretch forth the curtains of thy habitations: spare not, lengthen thy cords, and strengthen thy stakes" (Isaiah 54:2, King James Version). In the spirit of enlarging the tent and strengthening the stakes of the service-learning movement, Kenworthy-U'Ren's (1999, this issue) commentary to my article, "Service-Learning and Management Education: A Call to Action" (1999, this issue), proves a valuable and wonderful contribution. The strength of her commentary comes from …

Health, Health Insurance And The Labor Market, Janet Currie, Brigitte C. Madrian

Faculty Publications

This chapter provides an overview of the literature linking health, health insurance and labor market outcomes such as wages, earnings, employment, hours, occupational choice, job turnover, retirement, and the structure of employment. The ®rst part of the paper focuses on the relationship between health and labor market outcomes. The empirical literature surveyed suggests that poor health reduces the capacity to work and has substantive effects on wages, labor force participation and job choice. The exact magnitudes, however, are sensitive to both the choice of health measures and to identi®cation assumptions. The second part of the paper considers the link between …

He earned his Eagle Scout award about two years ago, and now in his spare time he lifts weights, practices his drums, and hangs out …

Atticus, David, And Raymond: Role Models For Ya Males, Chris Crowe

Faculty Publications

I can't listen to Bob Carlisle's "Butterfly Kisses," a sentimental song about a father and his daughter without crying. Every time I hear it, I want to pull my nearest daughter onto my lap, hold her tight, and bury my face in her shoulder while I cry about the eventual loss of my little girl. Unfortunately—or fortunately, if you're one of my daughters—my maudlin reaction to the song prompted my three teenage daughters to ban the recording from our home, so I rarely got to listen to it—and weep—anymore.

English Teachers Are From Mars, Students Are From Venus (But Ya Books Can Help Interplanetary Understanding), Chris Crowe

Faculty Publications

When I was a kid, people blamed the misunderstandings and tensions between grown-ups and teenagers on the "generation gap." Adolescents and adults butted heads because they were born in different times, into different circumstances. As a teenager with limited experience and understanding, I accepted that explanation as the reason why I didn't think or act the way my parents and teachers did.
