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 …

Curricular Approaches To Developing Positive Interethnic Relations, Rosemary C. Henze

Faculty Publications

This article examines whether and in what ways curricular approaches can be helpful in building positive interethnic relations in a large, ethnically diverse high school. Through this case study of curricular reform, the author documents four curricular approaches teacher leaders used to explicitly address issues of race and ethnicity and explores the impact of these approaches on student learning. By tracing the process of curricular change, the case illuminates how teacher leaders and administrators created the conditions for these curricular reforms to be sustainable.

President Julio Roca And The Welsh Communities Of Patagonia, Anne Fountain

Faculty Publications

Seen simply as reflections of Argentine history which share the relative tranquility of an attractive neighborhood in Buenos Aires, the Roca library and the Rawson statue seem unlikely links for a little-known chapter in the immigration annals of Argentina. But, in fact, both Rawson and Roca gave special consideration to the Welsh; both are remembered with appreciation; and Roca is something of a hero to the Welsh community because a century ago he personally intervened in an important dispute involving their religious beliefs. The significance of Roca's visits to the Welsh communities in Patagonia in 1899 is the focus of …

Comsumer Bankruptcy's New Clothes: An Empirical Study Of Discharge And Debt Collection In Chapter 13, Scott F. Norberg

Faculty Publications

Consumer bankruptcy filings hit another record high in 1998, with nearly 1.4 million consumers filing for bankruptcy relief. This trend sparked a debate in Congress about means-testing chapter 7 bankruptcy filings. Proponents of reform argued that it would curtail fraud and abuse. Opponents believed that consumer debt was swamping income growth, and that the deregulation of the consumer credit market had led to overgenerous lending and hence to more bankruptcies. This is an empirical study of whether filers for chapter 13 bankruptcy cases are abusing the system, or whether debtors are truly being swamped by debt in excess of their …

Identities And Racial Attitudes Of South African And American Adolescents: A Cross-Cultural Examination, Timothy B. Smith, Christopher R. Stones

Faculty Publications

Issues of group identity and prejudice have played a large role in the history of South Africa. This study examined differences among Xhosa-speaking Black, so-called Coloured, English-speaking White, and Afrikaans-speaking White adolescents within a context of social change. Data was collected from 818 high school students using a questionnaire that assessed aspects of these groups' perceptions of themselves (their identities), attitudes toward other racial groups (their prejudices), and beliefs about changes in the socio-political environment. Several statistically significant differences between the groups were found. Comparative analyses on identity and attitude variables performed with 263 White American adolescents were also statistically …

Characteristics Of A Full Disclosure, Transaction-Based Index Of Commercial Real Estate, David H. Downs, Barrett A. Slade

Faculty Publications

This study addresses the characteristics of a transaction-based index of commercial real estate as reported in a full-disclosure market. Prior research on transaction-based indices has enumerated various shortcomings for commercial real estate markets. This study circumvents many of these problems by using a large data set of commercial property transactions obtained for the Phoenix, Arizona metropolitan statistical area. The empirical analysis demonstrates that investors stand to gain considerable insight by comparing fulldisclosure, transaction-based indices with voluntarydisclosure, appraisal-based indices. The results suggest that full-disclosure indices avoid some of the institutional biases associated with other benchmarks of commercial real estate performance. In …

Where Do Resources Come From? A Model Of Resource Generation, Paul C. Godfrey, Hal B. Gregersen

Faculty Publications

Although the Resource-Based View of the firm (RBV) continues to gain centrality in the conversation of strategic management, several unanswered questions remain within the emerging paradigm. This article focuses on one of those questions. We propose a causal model of resource generation built around three central constructs: entrepreneurial ability, market context, and organizational context. Entrepreneurial ability generates new asset combinations that are valuable and unique, while market and organizational contexts preserve the value in these new asset combinations by providing barriers to imitation. We build a model and then consider three separate paths for generating idiosyncratic resources within a firm. …

Service-Learning And Management Education A Call To Action, Paul C. Godfrey

Faculty Publications

The private sector of United States society (private corporations) currently enjoys the moral authority to set the national agenda. Business schools, because they train future managers, can play a vital role in helping the private sector sustain that moral authority. Specifically, I argue that service-learning pedagogies offer management educators a way to incorporate citizenship skills and moral training into the traditional management curriculum. This article describes the concept of service-learning, reviews the current state of service-learning in management, and argues that service-learning can enhance both the technical capability and moral capability of students. Key issues for faculty members involved in …

Estimating Tourism's Economic Impact In Nebraska Counties, Brian J. Hill

Faculty Publications

Every community interested in developing tourism to enhance or diversify their economy wants to know how much good tourism can do for them. While tourism is not the answer to every community's economic challenges, it can provide economic benefits in many cases. These economic benefits must then be compared to the social, cultural and environmental changes that tourism might bring in order to judge its acceptability in community economic development efforts.

Politicians, planners and citizens want to know just how important tourism is to their communities. While some economic benefits and costs are very difficult to calculate, total economic impacts …

Exploiting Expertise Through Knowledge Networks, Michael N. Huhns, Larry M. Stevens

Faculty Publications

The paper discusses the necessary capabilities of knowledge networks: categorizing (the ability to classify Web pages and other unstructured data automatically); hyperlinking (the ability to add to each item of information appropriate pointers to other relevant items of information); alerting (the automatic notification of users and agents to new information that might be of interest to them); and profiling (the construction of models of users and agents to describe their interests and expertise).

Negotiating For Goods And Services, Michael N. Huhns, Anuj K. Malhotra

Faculty Publications

Can a negotiation protocol be both fair and “envy-free” when more than two agents are involved? The authors consider how envy-free apportioning is more difficult than fair apportioning, but both can help to manage critical resources. They discuss an envy-free protocol and agent-based Web auctions.

Networking Embedded Agents, Michael N. Huhns

Faculty Publications

Most of us will soon be managing an intranet in our homes, though we might not realize it. We might also be surprised at the devices that will be networked together. Just about every electrical device now contains one or more microprocessors. Designers typically find this a cost-effective way to provide device functionality, even when much of a processor's power is unnecessary or unused. For example, my coffee maker contains a processor, even though the appliance needn't be very smart and wastes most of its CPU cycles. Nevertheless, it is cheaper to include a general-purpose microprocessor than to incorporate custom …

Benevolent Agents, Michael N. Huhns, Abdulla Mohamed

Faculty Publications

Some agents roaming the Web these days are benevolent-for example, they may clean up stalled or failed database transactions, or share query results that may have cost substantial resources to acquire and might consume more to share. The Agent Behavior Testbed is a tool for studying the economics of agent altruism. As more agents hit the Internet, benevolence and cooperation will help with overall efficiency and productivity. The paper discusses benevolent agents on the Web.

Gathering To Nauvoo: Mormon Immigration 1840-46, Fred E. Woods

Faculty Publications

The gathering of the Mormon pioneers to Utah (commencing in 1847) has received extensive attention; however, the earlier LDS immigration to Nauvoo has not been adequately treated. This paper is the inspiring story of the British Saints who traveled to Nauvoo between June 1840 and February 1846. The international call to gather was received by the Prophet Joseph Smith during the second presentation of the Restored Church, less than six months after its organization in 1830.

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 …

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.

Structuring Time And Task In Electronic Brainstorming, Alan R. Dennis, Jay E. Aronson, William G. Heninger, Edward D. Walker Ii

Faculty Publications

There are many ways in which a GSS can beused to support group brainstorming. This paper reports the results of an experiment that manipulated task structure and time structure. Groups electronically brainstormed on intact tasks(where all parts of the task were presented simultaneously) or on partitioned tasks (where three subcategories of the task were presented to thegroups). The time periods in which groups worked were either one 30-minute time period or three 10-minute periods separated by two-minute breaks. Groups in the partitioned task treatment generated 40% more ideas, but there were no time effects. These differences are attributed to the …

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 …

Bilingual Creativity, Multidimensional Analysis, And World Englishes, Wendy Baker, William G. Eggington

Faculty Publications

Research in world English literatures has concentrated on qualitative measures of analysis in order to understand what is meant by `bilingual creativity.' These measures demonstrate that there are differences in rhetorical and literary style within world English literatures both in the inner and outer circle. Using Biber's multidimensional analysis (1988) to examine a large corpus of world English literatures written in Indian, West African, Britain, Anglo-American and Mexican American varieties of English, this paper examines whether quantitative analyses can also be insightful and useful in the examination of world English literatures in expanding our understanding of what `bilingual creativity' entails. …

Distribution Of Isolated Volcanoes On The Flanks Of The East Pacific Rise, 15.3°-20°S, Scott M. White, Ken C. Macdonald, Daniel S. Scheirer, Marie-Helene Cormier

Faculty Publications

Volcanic constructions, not associated with seamount (or volcano) chains, are abundant on the flanks of the East Pacific Rise (EPR) but are rare along the axial high. The distribution of isolated volcanoes, based on multibeam bathymetric maps, is approximately symmetric about the EPR axis. This symmetry contrasts with the asymmetries in the distribution of volcano chains (more abundant on the west flank), the seafloor subsidence rates (slower on the west flank), and the distribution of plate-motion-parallel gravity lineaments (more prominento nthe west flank). Most of the isolated volcanoes complete their growth within -14 km of the axis on crust younger …

Principal Component Mapping Applied To Raman Microspectroscopy Of Fiber-Reinforced Polymer Composites, C. M. Stellman, K. S. Booksh, A. R. Muroski, M. P. Nelson, Michael L. Myrick

Faculty Publications

We describe the development and implementation of a spectroscopic Raman imaging system using Principal Component data analysis. Raman microspectroscopy followed by multivariate data analysis and principal component mapping has been used to investigate the spatial variations of chemical and physical properties at interfaces in glass-reinforced composites on the micrometer scale. A protocol for monitoring chemical and physical variances via multivariate statistics has been developed and a preliminary study of a "real world" glass-reinforced composite is presented. It is demonstrated that multivariate Raman imaging is more precisely interpretable than traditional univariate methods and that by appropriately choosing distinct spectral regions (such …

What Can Humor And Advertising Teach Us About Legal Drafting?, Dallin D. Oaks, Jeremy Lewis

Faculty Publications

In his book Legal Drafting in a Nutshell, Haggard includes a useful chapter of nearly 50 pages in which he lists various lexical and structural elements and explains how these can lead to ambiguous writing. The kind of inventory approach that he presents is helpful and reveals that ambiguity doesn't just happen but often results from the careless use of identifiable structures or particular words.

A Work Minimization Approach To Image Morphing, Peisheng Gao, Thomas W. Sederberg

Faculty Publications

An algorithm is presented for morphing two images, often with little or no user interaction. For two similar images (such as different faces against a neutral background) the algorithm generally can create a pleasing morph completely automatically. The algorithm seeks the minimum work to deform one image into the other, where work is a function of the amount of warping and recoloration. A hierarchical method for finding a minimal work solution is invoked. Anchor point constraints are satisfied by imposing penalties on deformations that disobey these constraints. Good results can be obtained in less than ten seconds for 256 x …
