Parent And Child Perspectives Of Family Leisure Involvement And Satisfaction With Family Life, Ramon B. Zabriskie, Bryan P. Mccormick

Faculty Publications

The purpose of this study was to examine the relationship between family leisure involvement and satisfaction with family life. The sample consisted of 179 families. Data were analyzed at the parent, child, and family level. Findings indicated that family leisure involvement was the strongest multivariate predictor of family satisfaction from the parent perspective, but was not a significant multivariate predictor from the child's perspective. At the family level of measurement, only the block including Core and Balance family leisure variables explained a significant portion of the variance in family satisfaction. History of divorce was a negative multivariate predictor of family …

Faculty Publications

Use of the Internet for electronic business has the potential to revolutionize the way many businesses are conducted. Yet, several businesses have fallen victim to problems in information systems that facilitate e-Business. These problems are characterized by uncertainties due to system complexity, rapid development, interconnectivity, and a lack of familiarity with the new technologically based economy. This paper demonstrates how model checking can aid in the design and assurance of e- Business processes in environments characterized by distributed processing, parallelism, concurrency, communication uncertainties, and continuous operations.

Data Mining Of Forensic Association Rules, James V. Hansen, Paul Benjamin Lowry, Rayman D. Meservy

Faculty Publications

Data mining offers a potentially powerful method for analyzing the large data sets that are typically found in forensic computing (FC) investigations to discover useful and previously unknown patterns within the data. The contribution of this paper is an innovative and rigorous data mining methodology that enables effective search of large volumes of complex data to discover offender profiles. These profiles are based on association rules, which are computationally sound, flexible, easily interpreted, and provide a ready set of data for refinement via predictive models. Methodology incorporates link analysis and creation of predictive models based on association rule input.

An Imaging System Correlating Lip Shapes With Tongue Contact Patterns For Speech Pathology Research, Christopher Dromey, Daniel Bates, Xiaoqian Xu, Sameer Antani, D J. Lee

Faculty Publications

In this research, an imaging system was built to work with a newly developed electronic device to help people produce sounds correctly. The system consists of two parts, the internal tongue contact pattern data collection and the external lip shape information analysis. The tongue position information was gathered using the palatometer, an innovative tongue contact pattern-tracking device invented by Dr. Samuel Fletcher. The lip shape information was collected by processing images taken from people articulating different sounds. We developed an efficient color image segmentation technique to extract lip contour points and form a closed curve for shape analysis. The geometry …

A Memory-Based Approach To Cantonese Tone Recognition, Deryle W. Lonsdale, Michael Emonts

Faculty Publications

This paper introduces memory-based learning as a viable approach for Cantonese tone recognition. The memorybased learning algorithm employed here outperforms other documented current approaches for this problem, which is based on neural networks. Various numbers of tones and features are modeled to find the best method for feature selection and extraction. To further optimize this approach, experiments are performed to isolate the best feature weighting method, the best class voting weights method, and the best number of k-values to implement. Results and possible future work are discussed.

Effects Of Concurrent Motor, Linguistic, Or Cognitive Tasks On Speech Motor Performance, Christopher Dromey, April Benson

Faculty Publications

This study examined the influence of 3 different types of concurrent tasks on speech motor performance. The goal was to uncover potential differences in speech movements relating to the nature of the secondary task. Twenty young adults repeated sentences either with or without simultaneous distractor activities. These distractions included a motor task (putting together washers, nuts, and bolts), a linguistic task (generating verbs from nouns), and a cognitive task(performing mental arithmetic). Lip movement data collected during the experimental conditions revealed decreases in displacement and velocity during the motor task. The linguistic and cognitive tasks were associated with increased spatiotemporal variability …

Retribution For Rats: Cooperation, Punishment, And Atonement, Michael A. Simons

Faculty Publications

(Excerpt)

To mobsters, he is a "rat"; to drug dealers, a "snitch." To school children, he is a "tattletale"; to corporate executives, a "whistleblower." To cops, he is an "informant"; to prosecutors, a "cooperator." By whatever name he is known, the person who betrays his associates to the authorities is almost universally reviled. In movies, on television, in literature, the cooperator embodies all that society holds in contempt: he is disloyal, deceitful, greedy, selfish, and weak.

The cooperator, though, has long been a mainstay of our criminal justice system. For centuries, criminal defendants have received leniency in return for testimony …

Sequencing, Acoustic Separation, And 3-D Negotiation Of Complex Barriers: Charlene Barshefsky And Ip Rights In China, Rebecca Green, James K. Sebenius

Faculty Publications

Taking the perspective of the lead U.S. negotiator, Charlene Barshefsky, this article details and analyzes the negotiations that took place in the mid-1990s between the United States and the People's Republic of China over intellectual property rights (IPR). Employing a "negotiation analytic" methodology, Charlene Barshefsky's actions are interpreted to suggest a number of promising approaches to managing the daunting complexities of trade and other negotiations: recognizing the multiparty aspects of apparently bilateral dealings and capturing them in a "deal diagram;" carefully assessing "barriers" to agreement; sequencing to build a winning coalition and overcome potentially blocking ones; "acoustic separation" of issueframes; …

Sex Plus Age Discrimination: Protecting Older Women Workers, Nicole Buonocore Porter

Faculty Publications

There is little doubt that sexism and ageism still exist. To remedy these "isms," there are laws to protect both women and older workers from discrimination in the workplace, namely Title VII of the Civil Rights Act of 1964 ("Title VII"), which prohibits sex discrimination as well as discrimination based on many other protected categories, and the Age Discrimination in Employment Act of 1967 ("ADEA"), which prohibits age discrimination. Despite these protections, an older woman cannot bring a claim based on the fact that she feels she was discriminated against because she is an older woman. In other words, her …

Sea Surface Salinity Measurements In The Historical Database, Frederick M. Bingham, Stephan D. Howden, Chester J. Koblinsky

Faculty Publications

We have examined historical distributions of sea surface salinity (SSS) observations in a data set consisting of a combination of the World Ocean Database 1998 (WOD98) and a thermosalinograph and bucket salinity database collected from volunteer observing ships. It is well known that SSS in much of the world's ocean is measured infrequently or not at all. We find that 27% of one-degree squares in the world ocean (open and coastal, excluding the Arctic Ocean) had no observations of SSS in the historical database, and 70% had 10 or fewer. Systematic sampling of SSS (more than 10,000 observations per year …

Using Gis For Forest Recreation Planning On The Longleaf Ridge Special Area Of The Angelina National Forest, East Texas, I-Kuai Hung

Faculty Publications

Longleaf Ridge Special Area (LRSA) located in the Angelina National Forest is the westernmost example of a longleaf pine savanna community. Ecologically, the area is one of the most diverse communities in Texas. Due to its size, abundant natural and historical resources, numerous outdoor recreation opportunities exist. In this study, GIS was used to develop a forest recreation concept plan on LRSA. Most of the geospatial data came from public entities. Information for demand analysis on forest recreation was obtained from the 2000 National Survey on Recreation and the Environment database. U.S. Forest Service recreation fee envelope data were analyzed …

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 …

Coordinated Target Assignment And Intercept For Unmanned Air Vehicles, Erik P. Anderson, Randal W. Beard, Michael A. Goodrich, Timothy W. Mclain

Faculty Publications

This paper presents an end-to-end solution to the cooperative control problem represented by the scenario where unmanned air vehicles (UAVs) are assigned to transition through known target locations in the presence of dynamic threats. The problem is decomposed into the subproblems of: 1) cooperative target assignment; 2) coordinated UAV intercept; 3) path planning; 4) feasible trajectory generation; and 5) asymptotic trajectory following. The design technique is based on a hierarchical approach to coordinated control. Simulation results are presented to demonstrate the effectiveness of the approach.

The camera consists of 16 CCD devices arranged in a 4 × 4 mosaic covering 2.°3 × 3.°5 of sky. The CCDs are 2048 × 2048 LORAL devices with 15 μm pixels. The camera is optimized for drift-scan photometry and objective-prism spectroscopy. The design considerations, construction features, and performance parameters are described in the following paper.

Using A Computer Simulation To Teach Science Process Skills To College Biology And Elementary Majors, Aimée T. Lee, Rosalina V. Hairston, Rachel Thames, Tonya Lawrence, Sherry S. Herron

Faculty Publications

The Lateblight computer simulation (Arneson and Ticknor, 1990) has been implemented in the general biology laboratory and the science methods course for elementary teachers to reinforce the processes of science and to allow the students to engage, explore, explain, elaborate and evaluate the methods of building concepts in science. The students develop testable hypotheses and then use the program to run experiments and collect data. In addition, they research relevant background information and subsequently present their results in a poster during class.

A Circumpolar Perspective On Fluvial Sediment Flux To The Arctic Ocean, Robert M. Holmes, James W. Mcclelland, Bruce J. Peterson

Faculty Publications

Quantification of sediment fluxes from rivers is fundamental to understanding land‐ocean linkages in the Arctic. Numerous publications have focused on this subject over the past century, yet assessments of temporal trends are scarce and consensus on contemporary fluxes is lacking. Published estimates vary widely, but often provide little accessory information needed to interpret the differences. We present a pan‐arctic synthesis of sediment flux from 19 arctic rivers, primarily focusing on contributions from the eight largest ones. For this synthesis, historical records and recent unpublished data were compiled from Russian, Canadian, and United States sources. Evaluation of these data revealed no …

A Quantum Rosetta Stone For Interferometry, Hwang Lee, Pieter Kok, Jonathan P. Dowling

Faculty Publications

Heisenberg-limited measurement protocols can be used to gain an increase in measurement precision over classical protocols. Such measurements can be implemented using, for example, optical Mach-Zehnder interferometers and Ramsey spectroscopes. We address the formal equivalence between the Mach-Zehnder interferometer, the Ramsey spectroscope and a generic quantum logic circuit. Based on this equivalence we introduce the 'quantum Rosetta stone', and we describe a projective-measurement scheme for generating the desired correlations between the interferometric input states in order to achieve Heisenberg-limited sensitivity. The Rosetta stone then tells us that the same method should work in atom spectroscopy.

A Theoretical Framework For The Multicast Address Allocation Problem, Daniel Zappala, Chris Gauthierdickey, Virginia Lo, Timothy Singer

Faculty Publications

The multicast address allocation problem requires Internet domains to allocate unique addresses to multicast applications from a globally-shared space. We develop a theoretical framework for multicast allocation algorithms that is influenced by subcube allocation in hypercube computer systems. Based on this framework we derive complexity results for the address allocation problem and describe several new allocation algorithms that use a hypercube model for address representation.

Strong Founder Effect In Drosophila Pseudoobscura Colonizing New Zealand From North America, J. Reiland, S. Hodge, Mohamed A.F. Noor

Faculty Publications

The North American native species Drosophila pseudoobscura was first identified in New Zealand in the last few decades. Here, we have studied the genetic consequences of its spread across the Pacific Ocean. Using 10 microsatellites that are highly variable in North American populations, we found that the New Zealand population has substantially fewer alleles, a much lower average heterozygosity, and significantly different allele frequencies at these loci. We have discussed the relative sensitivity of these parameters for detecting the founding event. X-linked loci were more strongly differentiated between continents than autosomal loci, as reflected by larger changes in allele frequencies …

The Design And Evaluation Of Interactivities In A Digital Library, Muniram Budhu, Anita Coleman

The US National Science Foundation has established a program to create a National Science, Mathematics, Engineering and Technology Education Digital Library (NSDL). One of the subsidiary NSDL libraries under development is the National Civil Engineering Educational Resources Library (NCERL). The first phase of NCERL is the creation and collection of digital resources in three areas of civil engineering—geotechnical (soil), rock, and water engineering (GROW). The concept of interactivities guides the design, development, and evaluation efforts of the GROW digital collection. This article describes the salient features of GROW, defines and discusses interactivities as an emerging, integral part of teaching and …

Volcanic Mound Fields On The East Pacific Rise, 16˚-19˚S: Low Effusion Rate Eruptions At Overlapping Spreading Centers For The Past 1 Myr, Scott M. White, Ken C. Macdonald, John Sinton

Faculty Publications

Volcanic mound fields identified on SeaMARC II and HMR1 12 kHz side-scan data from the southern East Pacific Rise (SEPR) occur near overlapping spreading centers (OSCs) and migration traces of OSCs. The volcanic mound fields appear as a distinctive hummocky seafloor fabric due to side-scan backscatter reflections from clusters of moundshaped reflectors. The lack of growth of the mound fields away from the ridge axis, and their occurrence in association with OSC traces, suggests that mound fields form along the ridge crest near OSCs. Volcanic mound fields are found where 120 kHz side-scan and visual observations find fields of pillow …

Rf Rendez-Blue: Reducing Power And Inquiry Costs In Bluetooth-Enabled Mobile Systems, Eric S. Hall, Charles D. Knutson, David K. Vawdrey

Faculty Publications

In resource-limited mobile computing devices, Bluetooth wireless technology imposes a weighty burden due to inefficient power utilization and a sluggish device discovery process. Buttressing Bluetooth with Radio Frequency Identification (RFID) technology by performing an operation we call “Rendez-Blue” alleviates these limitations. In the Rendez-Blue process, an RFID signal is used as a cue to “wake-up” a sleeping Bluetooth radio. This ensures that the Bluetooth radio is active only when needed, significantly reducing power consumption. In addition, RFID is used to communicate Bluetooth device information, allowing the user to bypass the traditional 10.24-second discovery process.
