Contribution To The Morphology And Descriptive Biology Of Caurinella Idahoensis (Ephemeroptera: Ephemerellidae), Luke M. Jacobus, W. P. Mccafferty

Western North American Naturalist

Reared specimens from Bridge Creek, Idaho County, Idaho, provide the bases for the first descriptions of Caurinella idahoensis egg and alate stages and redescription of the larval stage. Larvae are distinguished from other Nearctic Ephemerellinae species by the distinctive posterolateral projections on abdominal segment 9. Male adults have a unique combination of characters associated with their genitalia. Larvae were associated with the colonial bluegreen alga Nostoc parmelioides in a clear, cold headwater stream. Several other Diptera, Ephemeroptera, Plecoptera, and Trichoptera also were found in cohabitation with C. idahoensis. Amorphous detritus appears to be a major component of the diet …

Conservation, Status, And Life History Of The Endangered White River Spinedace, Lepidomeda Albivallis (Cyprinidae), G. Gary Scoppettone, James E. Harvey, James Heinrich

Western North American Naturalist

Lepidomeda albivallis (White River spinedace), a fish species endemic to the White River, Nevada, appeared headed toward extinction. In 1991 only 1 population remained, and it comprised fewer than 50 individuals in a 70-m stream reach. We monitored population recruitment and distribution and studied life history and habitat use from 1993 through 1998. We determined that L. albivallis was not reproducing and was continuing to decline, and as an emergency measure we relocated the population (14 in spring 1995 and 6 in spring 1996) downstream 200 m to a secure habitat that we judged more favorable for reproduction. The relocated …

Comments On Hilbert Transform Based Signal Analysis, David G. Long

Faculty Publications

The use of the Hilbert transform for time/frequency analysis of signals is briefly considered. While the Hilbert transform is based on arbitrary continuous signals, most practical signals are digitially sampled and time-limited. To avoid aliasing in the sampling process the signals must also be bandlimited. It is argued that it is reasonable to consider such sampled signals as periodic (this is the basis of the Discrete Fourier Transform [DFT]) since any other interpretation is inconsistent. A simple derivation of the Hilbert transform for a sampled, periodic is then given. It is shown that the instantaneous frequency can be easily computed …

Integrated Microbattery Charger For Autonomous Systems, Brian W. Lefevre

Theses and Dissertations

This thesis presents a microbattery recharging circuit suitable for autonomous microsystems. The battery charger chosen for this design is a constant current battery charger. Two methods of regulating the constant-current are discussed. A published shunt regulator design is analyzed and is presented with enhancements to the design. A series regulator that controls the current to the battery with a switch is designed and fabricated in a 1.5µm CMOS process. The fabricated prototype occupies less than 2.20x2.20mm and is expected to dissipate less than 25µW of power. A discrete model of the integrated circuit is constructed and tested to demonstrate that …

Measuring Prejudiced Attitudes Toward Mexicans In Latter-Day Saint Missionaries During Missionary Service In The American Southwest, Jared A. Montoya

Theses and Dissertations

The purpose of this study was to investigate the foundations of prejudiced attitudes toward Mexicans held by White Americans and to investigate a means of reducing it, paying specific attention to prejudice found within a subpopulation of White Americans. The origins of American prejudice toward Mexicans are outlined using both historical and psychological explanations. An understanding of these origins leads to the notion that increased favorable contact is the best method for reducing prejudice. A field study focusing on prejudice toward Mexicans among ecclesiastical volunteers demonstrated that missionary service can be considered a means of favorable contact. Eighty-one White American …

Studies In Multiple-Antenna Wireless Communications, Christian Bruce Peel

Theses and Dissertations

Wireless communications systems are used today in a variety of milieux, with a recurring theme: users and applications regularly require higher throughput. Multiple antennas enable higher throughput and/or more robust performance than single-antenna communications, with no increase in power or frequency bandwidth. Systems are required which achieve the full potential of this "space-time" communication channel under the significant challenges of time-varying fading, multiple users, and the choice of appropriate coding schemes. This dissertation is focused on solutions to these problems. For the single-user case, there are many well-known coding techniques available; in the first part of this dissertation, the performance …

Prediction Of Ground Water Vulnerability Using An Integrated Gis-Based Neuro-Fuzzy Techniques

Journal of Spatial Hydrology

There is a need to develop new modeling techniques that assess ground water vulnerability with less expensive data and which are robust when data are uncertain and incomplete. Incorporation of Geographic Information Systems (GIS) with a modeling approach that is robust has the potential for creating a successful modeling tool. The specific objective of this study was to develop a model using Neuro-fuzzy techniques in a GIS to predict ground water vulnerability. The Neuro-fuzzy model was developed in JAVA using four plausible parameters deemed critical in transporting contaminants in and through the soil profile. These parameters include soil hydrologic group, …

Modeling Groundwater Flow For The Delineation Of Wellhead Protection Area Around A Water-Well At Nachole Of Bangladesh.

Journal of Spatial Hydrology

Delineation of wellhead protection area is an important component of groundwater contamination protection strategy to prevent probable environmental and health hazards. Modeling of ground water infiltration and movement in the wellhead area is a critical part of any effective wellhead protection program. Such models depend on an accurate description of the aquifer in the wellhead area for the reliable estimation of contaminant travel times and defining protection area. In this paper, a two-dimensional groundwater flow model is proposed for the estimation of contaminant travel time to water well and delineation of wellhead protection area. The model is applied for the …

The Morality Of Misogny: The Case Of Rustico Filippi, Vituperatore Of Women, Fabian Alfie

Quidditas

At the outset of his influential study on Rabelais, Mikhail Bakhtin makes an interesting observation. The scholar dedicates several pages to detail how the French author’s critical reception changed over time. Bakhtin illustrates how the attempt to comprehend an author can frequently be stymied by the cultural changes that occur across the centuries. As scholars analyze writers of earlier periods, the investigation of the cultural and textual background can become increasingly difficult.

Young Heber J. Grant's Years Of Passage, Ronald W. Walker

BYU Studies

As Heber J. Grant came of age, Mormonism was as much a part of the Utah landscape as the territory's dusty valleys and vaulting mountain walls. Young Heber met religion everywhere—in his Salt Lake City home and neighborhood, at the Tabernacle on Temple Square, in the offices of Church and civic leaders where he sometimes ventured, and certainly in his native Thirteenth Ward, one of the most innovative and organizationally developed Latter-day Saint congregations of the time. Slowly young Heber internalized his religious culture, but not before encountering the usual perils of adolescence and coming of age. The process tells …

Heber J. Grant And The Utah Loan And Trust Company, Ronald W. Walker

BYU Studies

Before 6:00 A.M. on May 29, 1897, the portly and veteran Apostle Brigham Young Jr., himself ailing due to an attack of dropsy, called at the Heber J. Grant household to pray a blessing upon his associate. He found that "Bro Grant... had a poor night but he was going to the hospital with firm faith that all would be well." The day before, Grant awoke with sever lumbar and abdominal pain. The doctors diagnosed a ruptured appendix and advanced peritonitis and advised immediate surgery. As the hour-and-a-half operation progressed, the nine attending surgeons found "extraordinary suppuration and commenced mortification." …

Combining Learning Approaches For Incremental On-Line Parsing, Deryle W. Lonsdale, Michael B. Manookin

Faculty Publications

This paper discusses the integration of two different machine learning approaches to modeling language, NL-Soar and analogical modeling (AM). The resulting hybrid system is capable of functionality that is not possible when using only one of the systems in isolation. After a brief introduction of each system, an explanation is given of how AM is used to provide information useful to NL-Soar for two tasks. Examples are given, and related issues are outlined.

The Language Contact Profile, Barbara F. Freed, Dan Dewey, Norman Segalowitz, Randall Halter

Faculty Publications

Efforts to gather data of various sorts—demographics, language-learning history, contact with native speakers, use of the language in the field—as they relate to participants in SLA research studies are inherent to understanding more about language acquisition and use. Scholars frequently develop questionnaires of their own, which are rarely shared widely in the profession. Consequently, much time and effort is invested in reinventing the process of gathering the types of data that are commonly needed.

The document we present here—a questionnaire to assess second language contact for students entering and completing language study programs in various contexts of learning (academic classrooms, …

Contributions Of Family Leisure To Family Functioning Among Transracial Adoptive Families, Ramon B. Zabriskie, Patti Freeman

Faculty Publications

The purpose of this study was to examine family leisure behavior among intact families with transracial adoptive children and make comparisons to a broad sample of families with only biological children. The sample consisted of 197 adoptive families. Data were analyzed from a parent, youth, and family perspective. The Family Leisure Activity Profile (FLAP) was used to determine family leisure involvement. FACES II was used to measure family functioning. Findings indicated that measures of family cohesion, family adaptability, and family functioning were higher among the adoptive family sample. Core, balance, and total family leisure involvement were also higher among the …

The Influences Of Family Leisure Patterns On Perceptions Of Family Functioning*, Ramon B. Zabriskie, Bryan P. Mccormick

Faculty Publications

This study conducted a preliminary test of a model of family leisure functioning by examining the relationship of core and balance family leisure patterns to family cohesion and adaptability. We hypothesized that core family leisure patterns address family needs for stability, facilitate the development of cohesive relationships, and are related to perceptions of family cohesion, whereas balance family leisure patterns address family needs for change, facilitate the development of adaptive skills, and are related to perceptions of family adaptability. Findings from 2 multiple regression analyses provided preliminary support for the model. Conclusions and implications are discussed.

Employee Investment Decisions About Company Stock, James J. Choi, David Laibson, Brigitte C. Madrian, Andrew Metrick

Faculty Publications

Recent high-profile cases have illustrated the dangers of employee investment in company stock. These debacles are unlikely to be the last ones, or even the most severe. Companies with more than 50 percent of retirement assets in company stock are common, and fractions over 80 percent continue to prevail at such large companies as Procter & Gamble, Anheuser- Busch, and Pfizer.¹

The concentration of retirement wealth in company stock is a clear violation of diversification principles. Recently, several studies have quantified the economic costs of this concentration. Muelbroek (2002) uses a Sharperatio approach and finds that the average diversification …

Market Reaction To The Expiration Of Ipo Lockup Provisions, James C. Brau, David A. Carter, Stephen E. Christophe, Kimberly G. Key

Faculty Publications

Initial public offering (IPO) lockup agreements prevent insider sale of shares for specified periods of time (often 180 days). This study investigates share price reactions at and around the time the lockup agreements expire. Results indicate statistically significant negative abnormal returns in the event window surrounding the expiration date. The results are consistent with informational asymmetries and decreasing incentive alignment between insiders and general shareholders. In addition, multivariate analysis identifies several variables that help explain these abnormal returns.

Redesigning The Teacher Education Technology Course To Emphasize Integration, Charles R. Graham, Richard Culatta, Mitchell Pratt, Richard West

Faculty Publications

Teacher education programs in the United States are trying to equip tomorrow’s teachers with the technology skills needed to impact learning in the classroom. During the past decade there has been a realization that teaching technology skills alone is not adequate– pre-service teachers must also learn how to integrate the use of technology into their curriculum. This paper describes BYU’s instructional technology course and the design process that a team of instructors went through to redesign the course in order to put greater emphasis on technology integration. An iterative redesign approach was used. Several iterations of the course redesign will …
