The Relations Between Knowledge, Search Strategy, And Performance In Unaided And Aided Information Search, John A. Barrick, Brian C. Spilker

Faculty Publications

Information search is a critical step in resolving complex issues in many different decisionmaking domains. This study examines the relations between knowledge, search strategy, and performance in both unaided and aided information search. The results of an experiment indicates that (a) task-relevant knowledge is directly related to performance in aided but not in unaided information search; (b) in unaided information search, search strategy mediates the relation between knowledge and performance; that is, knowledge indirectly affects performance through its effect on search strategy; and (c) an information search aid moderates both the relation between knowledge and search strategy and the relation …

The Ecosystem Of Partnerships: A Case Study Of A Long-Term University-Community Partnership, Gary Daynes, Scott L. Howell, Nathan K. Lindsay

Faculty Publications

This article presents a case study describing a robust fortyeight- year partnership between the Boy Scouts of America, Brigham Young University, Utah Valley State College, and others in an annual merit badge Powwow1 for Boy Scouts. Service-learning occurs as five hundred university students and faculty prepare for and teach merit badge classes to five thousand Boy Scouts as part of this Powwow. The article presents the history and operation of the Powwow, describes benefits to participants, and identifies some of the factors that contribute to the enduring nature of the partnership. The case study suggests that partnerships are similar to …

Blending Face-To-Face And Distance Learners In A Synchronous Class: Instructor And Learner Experiences, P. Clint Rogers, Charles R. Graham, Rus Rasmussen, J. Olin Campbell, Donna M. Ure

Faculty Publications

Like many institutions, Brigham Young University (BYU) is searching for ways to extend the reach of its programs without expanding the physical classroom and without incurring unreasonable costs. Internet supported instruction provides one alternative, with millions of students already attending Web-based classes (Gubernick & Ebeling, 1997). This case study examines the development of a class that blends distance and face-to-face students in a synchronous class. This case study focuses on how this blended learning environment was experienced by the distance and face-to-face students as well as the instructor.

Blended Learning Environments Definitions And Directions, Russell T. Osguthorpe, Charles R. Graham

Faculty Publications

During the past decade the availability of computer technologies, such as the Internet, have greatly expanded the educational options available to learners and instructors alike. Innovative uses of technology have begun to blur the distinctions between traditional face-to-face and more recent distance learning environments. As the learning environments have been combined, many have recognized the inherent strengths and weaknesses associated with both.

Being And Acting Rational, Michael N. Huhns

Faculty Publications

Rationality alone is insufficient to specify agent design. Using economic theory, we can program agents to behave in ways that maximize their utility while responding to environmental changes. However, economic models for agents, although general in principle, are typically limited in practice because the value functions that are tractable essentially reduce an agent to acting selfishly. Building a stable social system from a collection of agents motivated by self-serving interests is difficult. Finally, understanding rationality and knowledge requires interdisciplinary results from artificial intelligence, distributed.

Predicting The Readability Of Transparent Text, Lauren F. V. Scharff, Albert J. Ahumada Jr.

Faculty Publications

Will a simple global masking model based on image detection be successful at predicting the readability of transparent text? Text readability was measured for two types of transparent text: additive (as occurs in head-up displays) and multiplicative (which occurs in see-through liquid crystal display virtual reality displays). Text contrast and background texture were manipulated. Data from two previous experiments were also included (one using very low contrasts on plain backgrounds, and the other using higher-contrast opaque text on both plain and textured backgrounds). All variables influenced readability in at least an interactive manner. When there were background textures, the global …

Nonadditive Genetic Effects In Animal Behavior, Lisa M. Meffert, Sara K. Hicks, Jennifer L. Regan

Faculty Publications

Heritabilities, commonly used to predict evolutionary potential, are notoriously low for behaviors. Apart from strong contributions of environmental variance in reducing heritabilities, the additive genetic components can be very low, especially when they are camouflaged by nonadditive genetic effects. We first report the heritabilities of courtship traits in founder‐flush and control populations of the housefly (Musca domestica L.). We estimated the heritability of each male and female display through the regression of the courtships involving daughters and sons (with randomly selected mates) onto the “midparental” courtship values of their parents. Overall, the average heritability was significantly higher for the …

Brain Potentials Elicited By Prose-Embedded Linguistic Anomalies, Mark D. Allen, Kayo Inoue, Judith Mclaughlin, Lee Osterhout

Faculty Publications

Linguistic theories distinguish between syntax (sentence form) and semantics (sentence meaning). Correspondingly, recent studies have shown that syntactic and semantic anomalies elicit distinct changes in the event-related brain potential (ERP). However, these results have been obtained with highly artificial methodologies and have not yet been generalized to more natural reading conditions. Here, we recorded ERPs while subjects read a naturalistic prose passage. The subjects either read for comprehension with no other task being assigned or read for comprehension and made acceptability judgments after each sentence. Consistent with prior work and regardless of the subjects’ assigned task, syntactic anomalies elicited a …

Relational And Physical Victimization Within Friendships: Nobody Told Me There'd Be Friends Like These, Nicki R. Crick, David A. Nelson

Faculty Publications

In past research, relational and physical forms of peer victimization have been identified that have been shown to be significantly associated with social–psychological maladjustment. These forms of victimization, although studied primarily within the group peer context, also occur within dyadic relationships such as friendships. Gender differences in friend victimization and the association between friend victimization and children's social–psychological adjustment were examined. Results showed that boys were more physically victimized by their friends than were girls. Girls were more relationally than physically victimized by their friends. Friend victimization was related to adjustment difficulties for both boys and girls; however, friend physical …

Activity Patterns And Correlates Among Youth: Differences By Weight Status, Wendell C. Taylor, James F. Sallis, Marsha Dowda, Patty S. Freedson, Karen Eason, Russell R. Pate

Faculty Publications

The purposes of the study were to assess differences in physical activity levels and correlates of physical activity among overweight (‡ 85th percentile of body mass index for their sex and age) and non-overweight (< 85th percentile) youth. The sample included 509 seventh through twelfth graders. Activity was measured by a 7-day, 46-item activity checklist. Overweight girls were more sedentary than non-overweight girls (p<.03), and non-overweight girls engaged in more vigorous physical activity than overweight girls (p<.03). For boys, there were no significant differences in activity. The regression analyses for vigorous activity yielded the largest total R²'s (R²=.049 for overweight and R²=.27 for non-overweight.) The significant factor for overweight youth was greater athletic coordination (p<.01). For non-overweight youth, the significant factors were greater family support (p<.05), greater peer support (p<.001), fewer barriers (p<.03), and greater athletic coordination (p<.01). Correlates of physical activity vary by weight status of young people.

An Evaluation Of Factors Related To The Disproportionate Representation Of Children Of Color In Santa Clara County’S Child Welfare System: Child And Family Characteristics And Pathways Through The System Phase 2, Alice Hines, Peter Lee, Laurie Drabble, Lonnie Snowden, Kathy Lemon Osterling

Faculty Publications

While child abuse and neglect appears to affect children of all racial and ethnic origins (US Department of Health and Human Services, 1998; Sedlack & Broadhurst, 1996), an analysis of national, California and Santa Clara County data on the ethnicities of children in out of home placement reveals that, compared to their presence in the general population, there is a disproportionate involvement of children of color in the public child welfare system (CWS). In Santa Clara County, in particular, when compared to the general population, African American, Hispanic/Latino and Native American children are overrepresented in the CWS, while Asian American/Pacific …

I Am/Was The Walrus, Daniel Beller-Mckenna

Faculty Publications

For most of his adult life, John Lennon fought to define himself against his public identity as "Beatle-:John." That image, crafted by the Beatles' manager Brian Epstein and the pop music industry became a burden to all four of the Beatles during the group's seven years of international star-dom. In place of the rough leather-clad rock and roll band that played rambling one hour sets in the Hamburg Kaiserkeller and the Liverpool Cavern Club during 1960-61, Epstein forged a more commercially viable group of four well (and uniformly) dressed young men whose stage act was reduced to twenty minute carefully …

Integrating Marriage Education Into Perinatal Education, Alan J. Hawkins, Tamara Gilliland, Glenda Christiaens, Jason S. Carroll

Faculty Publications

Couples making the transition to parenthood experience challenges that can threaten the quality and stability of their relationships and the health of family members. Currently, the educational infrastructure to support the delivery of couple-relationship education during the transition to parenthood is limited. Because new-parent couples interact with the health care system at many points during this transition time, an opportunity exists for strengthening couple relationships within the system to improve the well-being of adults and children. in this article, we propose a productive collaboration between marriage/couple educators and health care systems to integrate couple-relationship education into the standard of perinatal …

Seeking Salvation For Accountability, Melvin J. Dubnick

Faculty Publications

This is a paper in defense of a concept that is threatened by its popularity and undermined by those who use it most. It is a call for a reexamination and reaffirmation of “accountability” from the perspective of its central role in modern governance. It is a plea for saving the concept of accountability from the abuses it suffers in the hands of friends and advocates. It is an effort at salvation for a concept that has lost its meaningful “soul” in a world filled with rhetoricians, reformers, and functionalists – all well intentioned, but each contributing to accountability’s fall …

Interdisciplinarity: The Road Ahead For Education In Digital Libraries, Anita Coleman

Faculty Publications

This article reviews the state of education in digital libraries and curriculum planning documents from professional associations in two areas: Library and Information Science; and Computing. It examines suggestions for integration and interdisciplinarity in education for digital libraries curricula using definitions of a discipline, interdisciplinarity, and the transdisciplinary structure of a university in order to discover how such integration may be successfully accomplished. A plan to use learning communities and develop an interdisciplinary curriculum for Knowledge Organization is briefly discussed.

Swift Neighbors And Persistent Strangers: A Cross-Cultural Investigation Of Trust And Reciprocity In Social Exchange, Nancy R. Buchan, Rachel T.A. Croson, Robin M. Dawes

Faculty Publications

In four countries, levels of trust and reciprocity in direct-reciprocal exchange are compared with those in network-generalized exchanges among experimentally manipulated groups’ members (neighbors) or random experimental participants (strangers). Results show that cooperation decreases as social distance increases; and, that identical network-generalized exchanges generate different amounts of trusting behavior due solely to manipulated social identity between the actors.

This study demonstrates the interaction of culture and social identity on the propensity to trust and reciprocate and also reveals differing relationships between trust and reciprocation in each of the four countries, bringing into question the theoretical relationship between these cooperative behaviors.

After Ellerth: The Tangible Employment Action In Sexual Harassment Analysis, Susan Grover

Faculty Publications

In this Article, Professor Grover argues that courts too readily allow employers to avoid vicarious liability far supervisors' unlawful sexual harassment of subordinates. The Article explores the breadth of the affirmative defense first introduced in the Supreme Court's 1998 cases of Faragher v. Boca Raton and Burlington Indus., Inc. v. Ellerth. That defense clears an employer of liability for a supervisor's unlawful sexual harassment if (a) the employer exercised reasonable care to prevent and correct promptly any sexually harassing behavior, and (b) the plaintiff employee unreasonably failed to take advantage of any preventive or corrective opportunities provided by the employer …

Parental Substance Use Disorder And The Risk Of Adolescent Drug Abuse: An Event History Analysis, John P. Hoffmann, Felicia G. Cerbone

Faculty Publications

A common observation in the research literature is that children of drug-dependent parents are at significantly heightened risk of adolescent drug use, abuse, and dependence. Recent research indicates that several psychological and interpersonal factors may affect the association between parents’ psychoactive substance use disorder (PSUD) and drug use risks among adolescents, yet studies have failed to examine explicitly whether these factors moderate the association between PSUD and adolescent substance abuse. This paper explores these potential relationships using longitudinal data from a study that has followed three cohorts of adolescents and their families over a 7-year period. The cohorts are defined …
