A conceptual model of the roles of price, quality, and intermediary constructs in determining behavioral intention to visit a festivalLee, So Yon 16 August 2006 (has links)
A clear understanding of the relationship among three performance indicators (perceived service quality, perceived service value, and satisfaction) would inform tourism businesses and organizations which of these evaluation measures were the most useful indicators of visitorsÂ behavioral intentions. Perceived service quality is a userÂs judgment about a serviceÂs overall excellence or superiority (Berry, Parasuraman and Zeithaml 1988). Perceived service value has been recognized in the past decade as one of the most salient determinants of purchase intention and repeat visitation (Bolton and Drew 1991; Chang and Wildt 1994; Jayanti and Ghosh 1996). Previous studies (Grewal, Monroe and Krishnan 1998; Jayanti and Ghosh 1996; Oh 1999; Sweeney, Soutar and Johnson 1997; Zeithaml 1988) suggested that perceived service value which is defined as a trade-off between visitorsÂ perceptions of the ÂgiveÂ and ÂgetÂ components of a service (Zeithaml 1988) mediates the influence of perceived price and perceived service quality. Satisfaction is a visitorÂs affective and evaluative response to the overall product or service experience (Oliver 1997). What visitors receive from their investment (money, time and other resources) on a tourism trip are psychological benefits. Thus, it is an experience that visitors receive from interacting with the tourism product, and satisfaction is an evaluation of the level to which these psychological benefits are received (Crompton and Love 1995). This study is an examination of the relationships between visitorsÂ perceived service quality, perceived service value, satisfaction and behavioral intentions. Respondents were visitors who attended the Cajun Catfish Festival in Conroe, Texas and were systematically selected. Findings revealed that: a) a structural model operationalizing perceived service quality as a set of attributes fit the data better than an alternative model that measured quality by using a visitorÂs judgment about a serviceÂs overall excellence or superiority; b) among the constructs analyzed perceived service value appeared to be the best predictor of behavioral intentions; and c) of the four dimensions of service quality of a festival, generic features and comfort amenities had the most influence on determining perceived service quality.

End-user authored tutorials are increasingly becoming the norm for assisting users with learning software applications, but little is known about the quality of these tutorials. Using metrics derived from previous work, I characterize the quality of text- and image-based Photoshop tutorials available to users online. I compare these tutorials across four sources representing tutorials that are, i) written by a close-knit online community, ii) written by expert users, iii) most likely to be found, and iv) representative of the general population of tutorials. I found that not only are expert users generally writing higher quality tutorials than the other authors, but also, many of the typical tutorials are suffering from some important limitations. Most notably, they often lack attempts to help users avoid common errors, and seldom provide users with appropriate amounts of reasoning for undertaking steps. I also examine a typical tutorial rating system and find that it does not sufficiently distinguish quality between tutorials. I demonstrate the use of my findings by presenting two applications that I designed: a tutorial authoring tool, and a tutorial presentation site.

In a communication system, audio quality is one of the parameters by which the end user defines the value of a product. This thesis examines the term audio quality, breaking it down into two subsidiary components, speech quality and speech intelligibility. One key goal in assessing audio quality is quantifying it in an accurate and repeatable way. As a part of this project a system was developed that achieved this goal. The system was then used to evaluate a number of existing products based on speech quality and intelligibility. Using these results the relationship between the two parameters was investigated. Investigations were also conducted in order to determine and quantify the effect communication systems have on perceptual speech parameters, and examine the relationship between them and speech quality and intelligibility. Using the testing systems developed a possible method of audio quality optimization was investigated and tested. The analysis methods that were incorporated into the test suite included the Perceptual Evaluation of Speech Quality, the Speech Transmission Index, vowel space analysis and segmental, psychoacoustic based methods. The testing incorporated a number of different handheld portable radios as speakers.

This study investigated the quality of braille transcription in public schools in Texas. In the first phase, an electronic survey of 94 school personnel across the state found that instructional materials are often transcribed by a variety of personnel not certified by the Library of Congress. In addition, the majority of survey respondents felt that their initial training had not adequately prepared them. Not surprisingly, transcribers and braillists reported that they spent more time each week transcribing materials than did teachers of the visually impaired. In the second phase, 40 transcriptions prepared by school personnel were examined. The quality of the transcriptions varied greatly. More than 30% (n=13) of the transcriptions contained four or less errors. The other transcriptions (n=27) contained a variety of contraction errors, misspelled words, misformed characters, omission of letters or words, insertion of additional letters, detectable erasures, and formatting errors. Perception of quality by the person transcribing often did not reflect the actual quality of the transcription. The data in this study indicated that neither years of experience nor certification status have a decisive effect on quality. On the other hand, the salient characteristic in predicting the quality of braille produced by the participants was time spent each week transcribing materials, which, in turn, was associated with the job role of the participant. In the third phase, members of a focus group assessed a representative subset of the transcriptions. The findings of the focus group revealed that errors would prevent legibility for some students, and that errors in transcribing negatively affect the academic performance of braille readers. The data in all three phases supported the need for developing a formal definition of quality in braille transcribing and providing ongoing, standardized training for school personnel. Perhaps most importantly, the data gained from this study supported the hypothesis that braille readers receive instructional materials that are not equal in quality to those received by other students.
