Saying Goodbye: An Examination of the Leave-Taking Act<br />

The importance of conversational closings is examined. The prior research into the leave-taking act, including research into syntax,<br />

pragmatics and sociolinguistics is presented to provide a framework for this study. The frameworks, introduced by both Schegloff & Sacks<br />

(1969) and Wolfram & Schilling-Estes (2006), are compared. This research deals primarily with proper leave-taking techniques, and<br />

specifically is an investigation into the speech acts used during the leave-taking act. The leave-taking act consists of a passing phrase,<br />

some type of speech act as a leave-taking routine and possibly an adjacency pair. The concepts and effects of adjacency pairs and<br />

repetition throughout the leave-taking act are noted. Finally the social implications of the leave-taking act are investigated along with<br />

suggestions for future research into this linguistic phenomenon. This study encourages more empirical research so that the norms of a<br />

conversation closing in American English can be better understood.<br />

Tutoring <strong>St</strong>rategies for Developmental Writers<br />

This presentation will examine the roles a tutor can play in the education of developmental writers. A five-week case study examining the<br />

relationships between three tutors and six small groups of developmental writers will be presented and analyzed to show the effectiveness<br />

of various teaching and tutoring techniques. These techniques will focus on improving the student as a writer, not improving the piece of<br />

writing itself. <strong>St</strong>rategies focused on assisting developmental writers in one-on-one tutoring, small-group tutoring and in a classroom setting<br />

will be discussed. Also, sample handouts and plans for mini-lessons covering grammar, punctuation and other writing issues will be<br />

provided.<br />

Geothermal Heating of Airport Runways<br />

Keeping snow and ice from building up on airport runways and taxiways is an essential part of airport maintenance/operations worldwide<br />

and requires a large investment of time and money in equipment and operational control, especially in colder climates. Current methods<br />

for removing ice and snow from airport movement surfaces consist of spraying large quantities of anti-ice chemicals on the ground and<br />

deploying a great number of snowplowing vehicles. Both the chemicals and snowplowing vehicles have adverse effects on the<br />

environment as they contribute to pollution. During poor weather conditions, keeping runways open can be a challenge as snowplow<br />

crews cannot keep up with the precipitation, causing airport closures, delays and safety concerns. Ice buildup on runways has been<br />

proven to contribute to accidents involving runway runoffs. Heating runways with geothermal heat can prevent the buildup of ice and snow<br />

on runways and once installed, such a system could pay for itself in as little as 2-5 years. Geothermal heat has been used to melt ice and<br />

snow off roads, sidewalks, bridges and other paved surfaces for years in locations around the world. The design is simple, pipes are cut<br />

into the pavement that receive a flow of warm liquids, either from direct use geothermal water, where available, or through the use of heat<br />

exchanger systems or even hot runoff liquids from local industry or power plants . The most ideal locations to utilize geothermal heat are<br />

in areas where high-temperature water wells can be drilled for direct use. Such locations can be found through much of the western half of<br />

the United <strong>St</strong>ates.<br />
