Multi-Channel Retailing: Function of Consumers' Perceived Benefits and Costs and Retail Synergy

Multi-Channel Retailing: Function of Consumers' Perceived Benefits and Costs and Retail Synergy

Date: May 2003
Creator: Pookulangara, Sanjukta Arun
Description: This study investigated the consumers' intention towards multi-channel shopping and the function of synergy in a multi-channel retailing format (i.e., brick-and-mortar stores, catalogs, and the Internet). Two questionnaires were developed, one for the multi-channel consumers and the other for the multi-channel retailers. The structural equation modeling was used to predict the effect of shopping benefits and costs perceived from each channel on the consumer's purchase intention. Data analysis (N = 500) indicated that the purchase intentions were affected by different shopping benefit and cost variables. Qualitative analysis of retailers (N= 10) revealed that the retailers considered synergy to be an important part of their multi-channels. Also, there existed a high level of synergy among the existing three retail channels.

The Multipath Fault-Tolerant Protocol for Routing in Packet-Switched Communication Network

The Multipath Fault-Tolerant Protocol for Routing in Packet-Switched Communication Network

Date: May 2003
Creator: Krishnan, Anupama
Description: In order to provide improved service quality to applications, networks need to address the need for reliability of data delivery. Reliability can be improved by incorporating fault tolerance into network routing, wherein a set of multiple routes are used for routing between a given source and destination. This thesis proposes a new fault-tolerant protocol, called the Multipath Fault Tolerant Protocol for Routing (MFTPR), to improve the reliability of network routing services. The protocol is based on a multipath discovery algorithm, the Quasi-Shortest Multipath (QSMP), and is designed to work in conjunction with the routing protocol employed by the network. MFTPR improves upon the QSMP algorithm by finding more routes than QSMP, and also provides for maintenance of these routes in the event of failure of network components. In order to evaluate the resilience of a pair of paths to failure, this thesis proposes metrics that evaluate the non-disjointness of a pair of paths and measure the probability of simultaneous failure of these paths. The performance of MFTPR to find alternate routes based on these metrics is analyzed through simulation.

Date: May 2003
Creator: Blizzard, Amy
Description: This thesis surveys a variety of songs and arias for high soprano which feature the nightingale; examines the musical elements that symbolize, refer to, or imitate the nightingale; and compares these musical elements with transcriptions of the nightingale's song. The first chapter reviews the symbolic development of the nightingale and its role in poetry and literature. The interior chapters address a selection of musical compositions that feature the nightingale and its song. The final chapter establishes a relationship between the sound of the actual sound of the nightingale and the musical gestures created by composers to imitate the nightingale.

Date: May 2003
Creator: Wood, Kelly Thomas
Description: Now All the Fingers of This Tree is a work in two movements based upon a poem of the same name by E. E. Cummings. It is divided into two movements: The first movement is scored for nine part solo soprano, where one performer records each of the nine vocal lines. The second movement is an electro-acoustic work derived from four phrases of the original recording of the first movement. Total duration of the work is approximately 19 minutes. The paper provides a detailed analysis of both movements as well as a discussion on usage of text, problems addressed with traditional notation techniques, and technology utilized in the production of the work.

Octatonic pitch structure and motivic organization in George Walker's  Canvas for wind ensemble, voices, and chorus.

Octatonic pitch structure and motivic organization in George Walker's Canvas for wind ensemble, voices, and chorus.

Date: May 2003
Creator: Nelson, Ryan
Description: Canvas was commissioned by the College Band Directors National Association (CBDNA) Consortium in fall 1999 for the CBDNA Biennium National Conference to be held at the University of North Texas in February 2001. This substantial and profound three-movement work is Pulitzer Prize winning composer George Walker's first work for wind ensemble and is a milestone in wind composition at the turn of the millennium. This analysis considers Walker's sophisticated use of octatonic collections and their subsets. Walker uses the three transpositions of the octatonic scale as a harmonic framework for the work. Within this framework, specific subsets of the collection are used in traditional harmonic ways. A hierarchy of pitch sets is created, lending a "tonic" function characteristic to prevalent and specifically placed sonorities. Onto this "canvas" of octatonic harmonies, Walker "paints" specific motivic gestures. These motivic gesture monopolize specific intervallic relationships that are initially presented in the beginning of the work. Certain motivic techniques are then employed in the ongoing development of the motivic content. These motivic techniques include melodic suspension, interval alternation, double stroke articulation, irregularly recurring patterns, chordal punctuations, interrupted sequences, and dramatic uses of silence. Formally, Walker uses short "cells" of similar motivic and harmonic content ...

Creator: Dohanich, Francis Albert
Description: On-road remote sensing has the ability to operate in real-time, and under real world conditions, making it an ideal candidate for detecting gross polluters on major freeways and thoroughfares. In this study, remote sensing was employed to detect carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxide (NO). On-road remote sensing data taken from measurements performed in six states, (Arizona, California, Colorado, Illinois, Texas, and Utah) were cleaned and analyzed. Data mining and exploration were first undertaken in order to search for relationships among variables such as make, year, engine type, vehicle weight, and location. Descriptive statistics were obtained for the three pollutants of interest. The data were found to have non-normal distributions. Applied transformations were ineffective, and nonparametric tests were applied. Due to the extremely large sample size of the dataset (508,617 records), nonparametric tests resulted in "p" values that demonstrated "significance." The general linear model was selected due to its ability to handle data with non-normal distributions. The general linear model was run on each pollutant with output producing descriptive statistics, profile plots, between-subjects effects, and estimated marginal means. Due to insufficient data within certain cells, results were not obtained for gross vehicle weight and engine type. The "year" ...

Date: May 2003
Creator: Jones, Paul David
Description: Recently my creative process has led to a new area of investigation and exploration. I have discovered that I enjoy the unexpected occurrences that happen while painting. I have an appreciation for the parts of my works that do not follow the preliminary sketch and are produced more subconsciously. While usually this aspect has been restricted by the adherence to a preliminary sketch and narrative, the new works explore these occurrences more fully. In the new works, I worked in a more spontaneous manner to create work that does not focus strictly on narrative but reveals itself more as a journey or exploration.

A parametric analysis of the immediate and subsequent effects of response restriction on hand mouthing.

A parametric analysis of the immediate and subsequent effects of response restriction on hand mouthing.

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Soderlund, Michael J.
Description: The immediate and subsequent effects of different durations of response restriction were evaluated in a multiple schedule design. Response restriction components of 15, 30, and 60 minutes were conducted between 15 minute alone components. Levels of responding subsequent to the termination of response restriction procedures were compared to free operant levels prior to the implementation of response restriction. Responding during response restriction components reduced to near zero levels. Subsequent levels of responding were similar to or exceeded free operant baseline levels. Results are discussed in terms of potential operant mechanisms responsible for levels of responding subsequent to response restriction.

Participant's perceptions of online staff development and learning tools.

Date: May 2003
Creator: Smolka, Jennifer
Description: This study analyzed participants in an online professional development and certification program can to see if they could predict the learning value of individual distance education tools. The Texas Center for Educational Technology (TCET) funded by the Texas Telecommunications Infrastructure Fund (TIF) designed the Technology Applications Certification Program (TACP). In the TACP, students are offered four graduate level classes which, when combined, meet the standards for the State Board for Educator Certification (SBEC) Technology Applications certification. The four courses that comprise the TACP are Computers in Education, Introduction to the Internet, Multimedia in Technology Applications, and Introduction to Video Technologies. The first course started in January 2002 with approximately 706 participants in 40 cohorts across the state of Texas. The TACP combines two different worlds of technology training. Half of the coursework was completed through asynchronous content and discussions, while the remaining classes were hands-on classes in local district computer labs. These face-to-face meetings enabled learners to get hands-on training with direct assistance. Between the online and face-to-face segments, a variety of learning tools were introduced to the participants. Participants were surveyed through the online Snapshot Survey in January and again in September.

Perceived value of journals for academic prestige, general reading and classroom use: A study of journals in educational and instructional technology.

Perceived value of journals for academic prestige, general reading and classroom use: A study of journals in educational and instructional technology.

Date: May 2003
Creator: Bray, Kaye Evitt
Description: Conducting research, evaluating research, and publishing scholarly works all play an extremely prominent role for university faculty members. Tenure and promotion decisions are greatly influenced by the perceived value of publications as viewed by members of faculty evaluation committees. Faculty members seeking tenure may be limited to publishing in a limited group of journals perceived to be valuable by members of an academic committee. This study attempted to determine the value of various kinds of periodicals (journals, magazines, and e-journals), based on three principal criteria, as perceived by professionals (university faculty, K-12 practitioners, and corporate trainers) in the educational/instructional technology (E/IT) field. The criteria for journal evaluation were Academic Prestige, General Reading, and Classroom Use. The perceived value of journals based on each criterion was compared to determine any significant differences. Members of the Association for Educational Communications and Technology (AECT) were asked to rate 30 journals in the E/IT field using the three criteria. Statistically significant differences were found among ratings in 63% of the journals. The statistical analyses indicated that differences in the perceived value of journals among E/IT professionals across the three criteria (Academic Prestige, General Reading, and Classroom Use) were statistically significant. It is also noted ...
