Computer-mediated communication has been considered a viable tool for both the teaching of languages and the teaching of writing. There is, however, scant information on how computer-mediated peer response functions in the foreign language classroom. This dissertation investigated how college Spanish learners provided feedback to their peers and the impact of feedback on revision. It also examined the factors that influenced how students wrote their comments, and how they perceived the use of computers for peer response. Case study methodology was used to collect and analyze data from two writing tasks performed as part of a semester-long course. / ABSTRACT: Data sources consisted of written feedback, first and second drafts, interview transcripts, learning journals from 12 participants and the teacher-researcher field notes. Analysis of data indicated that peer response is a complex event, influenced by a variety of contextual factors. Results also indicated that the participants used feedback depending on their needs. Students used reacting, advising and announcing language functions when providing feedback, and focused mostly on content. The revisions made by the participants contradicted the idea that peer feedback directly influences revision; more than half of the revisions made by the participants originated in the writers themselves and not in the suggestions given by their peers. Analysis of the revisions made, based on peers' suggestions indicated that the impact of peer response was strong on the length of the essays, limited on their language below the clause level, and weak on the essays' communicative purpose. / ABSTRACT: The participants' language proficiency and the characteristics of the writing task were perceived by the participants as factors that influenced how they wrote feedback for their peers. Finally, although the students considered that using the word processing language tools allowed them to learn about language and focus on content, the role of technology was perceived as supplementary to oral peer response / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Along with the identication of various maternal risk factors, the role of fetal hypoxia has been hypothesized to be one of many causal factors associated with SIDS. The purpose of this study was to develop a profile of the SIDS infant and assess whether six pregnancy complications consistent with fetal hypoxia were associated with the increased outcome of SIDS. The secondary data analysis of Florida linked birth to death certificate data specific to Hillsborough County and Duval County were analyzed retrospectively for the period of time between 1998 and 2000. Of the 86, 342 births, 69 SIDS cases were identified, 34 in Hillsborough County and 35 in Duval County. / A majority of the infants were White males with an average age of death of 80 days. The Chi-Square test for Independence with Cramer's V, odds ratios and 95% confidence intervals were calculated to determine if an association existed between pregnancy complications, specific maternal risk factors and SIDS. Eclampsia was the only statistically significant prenatal complication found in this cohort (OR=4.67: 95% CI 1.49, 14.57). Maternal tobacco use (OR= 3.13: 95% CI 1.83, 5.36) and late initiation into prenatal care were also found to be significant in the SIDS cases, with the greatest risk occuring in women who did not receive prenatal care (OR=4.37: 95% CI 1.38, 13.89). These findings will assist with the development of a profile of infants who are at greater risk of dying of SIDS in Hillsborough County and Duval County as well as contribute to what is currently known about the association between fetal hypoxia and SIDS. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

The ASR, a jerk-like motor reflex, is elicited by bursts of noise or tones with sound pressure levels of 80-90 dB and greater. PPI is a type of modulation of the ASR, requires no training, and results in observable response in both mice and humans. Data were obtained from nine inbred mouse strains, sixteen per strain, which were shipped at approximately 3-5 weeks old from The Jackson Laboratory. In general, ASRs were generally smaller when the startle stimulus was less intense. PPI was relatively weak for the 4 kHz prepulse, and stronger with prepulses of 12 kHz and 20 kHz. However, means varied widely across strains for both ASR and PPI, suggesting a strong influence of genetic background on these behaviors. / ABSTRACT: In addition to genetic influences, peripheral hearing loss and central auditory processing factors must be taken into consideration. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Along the equator, warm pool thermodynamics and momentum are influenced by equatorial ocean visco-inertial boundary layer dynamics that occur within a few degrees of the equator because of the sign reversal of the Coriolis force. Designed to study this system, COARE Enhanced Monitoring Array (EMA) observations of temperature, salinity, velocity, and surface meteorology were centered at 0, 156°E from February 1992 through April 1994. They sampled variability on the equator over larger space/time-scales than the concurrent Intensive Flux Array (IFA) centered at 2°S, 156°E. The EMA data are examined within the context of the larger scale equatorial Pacific and the El Niño conditions that occurred at that time. / ABSTRACT: There is a structural change in the equatorial Pacific near the dateline resulting from the winds that are strong, steady, and easterly in the east and generally weak, punctuated by westerly wind bursts, in the west. East of the dateline the EUC's speed and transport increases downstream, while in the west it tends to be zonally uniform, consistent with the extra-tropical ocean interior water pathways that tend to converge on the equator east of the dateline. At 0°, 156°E in the western Pacific deep, seasonal upwelling (appearing stronger after the peak of the 1991/92 El Niño than during the following weaker El Niño year) occurs within the thermocline in boreal summer with magnitudes as large as upwelling in the eastern Pacific cold tongue. This large upwelling is associated with large downward turbulent heat flux and large turbulent shear stress. / ABSTRACT: While the inferred mixing is quantitatively inconclusive because of unresolved potential errors, it is consistent with the visco-inertial boundary layer concepts from early theory [e.g. Arthur 1960; Robinson 1960; Stommel 1960; and Charney and Spiegel 1971]. These findings suggest that the equatorial thermodynamics differ from those of the IFA. Further process experimentation is necessary to quantify these results. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

This research focuses specifically on U.S. foreign policy toward the Islamic nations of this region, Pakistan and Afghanistan (Referred to as Islamic South Asia). This research examines a variety of primary and secondary sources in an effort to understand the historical context and theoretical framework of U.S. policy. It has been suggested by scholars that the age of realism has come to an end. This study seeks to verify this claim. Does realism provide the theoretical base necessary for policy success in Islamic South Asia? If it does, then can it continue to serve as the theoretical guide in the post-Cold War era? U.S. policy actions and the logic supporting them are examined in an effort to critique realism and to assess the policy toward this region. / ABSTRACT: The purpose of this study is to examine whether the continued use of the realist theory is substantiated, based on its record of past policy successes and failures. One of the core arguments against realism is that the level of analysis is too rigid, thus failing to recognize internal constraints in state affairs. Of the many internal issues facing a state, none outweigh the role of culture within the social context of this region. This is exemplified in the case studies of the three most pivotal events influencing U.S. policy. Having examining the foundation and application of the realist based policies toward the region, this study will then evaluate the success or failure of U.S. policy. This evaluation is based on an analysis of the stated goals compared to the results of policy actions. Considering the dangers on the horizon, this research also offers several guidelines for creating a more successful long-term strategy toward Islamic South Asia. / ABSTRACT: Having already witnessed the collapse of the state in Afghanistan and the potential for state failure in a nuclear Pakistan, the concerns relating to this region are extensive. Weapons of mass destruction, environmental crisis, and social instability are just few of the problems addressed in this study. The variety of potential disasters emanating from this region makes this region and U.S. policy towards it a paramount concern. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

The rate at which these organisms remove a nutrient from the water column can be controlled by physical factors such as hydrodynamic regime or by biological factors such as speed of enzyme reactions. The impact of hydrodynamic regime on rates of nutrient uptake for seagrass (Thalassia testudinum) communities and for organisms that comprise the community (seagrass, epiphytes, phytoplankton, and microphytobenthos) was quantified in a series of field flume experiments employing the use of 15N-labeled ammonium and nitrate. Rates of ammonium uptake for the entire community and for seagrass leaves and epiphytes were significantly dependent on bulk velocity, bottom shear stress, and the rate of turbulent energy dissipation. / ABSTRACT: Relationships between uptake rates and these parameters were consistent with mass-transfer theory and suggest that the effect of water flow on ammonium uptake is the same for the benthos as a whole and for the organisms that form the canopy. In addition, epiphytes on the surface of T. testudinum leaves were shown to depress leaf uptake by an amount proportional to the area of the leaf covered by epiphytes. Water flow influenced rates of nitrate uptake for the community and the epiphytes; however, uptake rates were depressed relative to those for ammonium suggesting that uptake of nitrate was also affected by biological factors such as enzyme activity. Epiphytes reduced uptake of nitrate by the leaves; however, the amount of reduction was not proportional to the extent of epiphyte cover, which provided further evidence that nitrate uptake by T. testudinum leaves was biologically limited. / ABSTRACT: As an additional component of the research, hydrodynamic regime of a mixed seagrass and coral community in Florida Bay was characterized using an acoustic Doppler velocimeter. Hydrodynamic parameters estimated from velocity data were used in mass-transfer equations to predict nutrient uptake by the benthos over a range of water velocity. Measured rates of uptake from field flume experiments conducted in the same community confirmed that hydrodynamic data could be used to accurately predict nutrient transport to the benthos under natural flow conditions. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Despite an established pattern of depression and hopelessness leading to suicide in adults, no such pattern emerges in the adolescent literature. Recent investigations suggest that impulsivity may play a key role in adolescent suicide attempts. This study examined the role of impulsivity in adolescent suicidal gestures, as well as the relationships among demographic variables, anger expression, impulsivity, and suicidal behavior. A total of 100 participants (ages 11-17; 71 females and 29 males) were recruited from 2 inpatient crisis centers for children. The Children's Depression Inventory, Hopelessness Scale for Children, Adolescent Behavior Checklist, Pediatric Anger Expression Scale, and Suicide Intent Scale were administered to inpatients, and demographic information was obtained (age, gender, ethnicity, income, and structure of family). / ABSTRACT: It was hypothesized that patterns of depression, anger, hopelessness, and impulsivity would vary by age, gender, ethnicity, and suicidality (e.g., suicidal gesture vs. no gesture). The large majority of hypotheses were not supported. Results are explained in terms of alternative theories for the role of impulsivity in adolescent suicidal gestures. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Constructing such an argument, however, requires a similar building up from the parts, and so the core focus becomes a study on the way the image of an arch can serve as a metaphor for Pope's reconciliation scheme in his Moral Essays as he "steers betwixt" seeming opposites. To justify this approach, I note the works of critics who have studied Pope's use of the sister arts, the works of architectural theorists and historians, as well the works of critics who focus on various reconciliatory strategies. Perhaps more importantly, I look back to Pope's correspondence and Joseph Spence's record to establish not only Pope's interest in architecture, but also his actual architectural endeavors. / ABSTRACT: From this foundation, I relate Pope's intentions for his opus magnum and indicate the connections that can be drawn between the four epistles of Essay on Man and the four epistles that Pope selected to comprise the "death-bed" edition of his ethic work, namely To a Lady, To Cobham, To Bathurst, and To Burlington. Finally, I examine Pope's method of reconciling the extremes he presents by exemplum in the Moral Essays by comparing the personal and societal pressures that form the basis of Pope's satire to the vertical and lateral thrusts that enable an arch to stand, even as they threaten its destruction should the forces become unbalanced. From such an architectural perspective, one can trace Pope's conception of man in his middle state as he makes the transition from the abstract plan established in Essay on Man, through the pendentive formed by the arches of the Moral Essays, and ultimately to the ideal state of existence that is represented by the dome. / ABSTRACT: The final result can be conceived of as no less than a monument to Pope's life and art. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

The Judeo-Christian religious tradition and Locke's property theory provides much of the western cultural and historical basis of humans' environmental attitudes that basically engender exploitation. I argue that a more precise interpretation of Genesis and of Locke reveals that both sources actually promote environmental stewardship while decrying ecological abuse. Next I analyze the history and shortcomings of various wilderness concepts. These shortcomings are all forms of an exclusionist mentality and result in some harmful theoretical and practical applications. / ABSTRACT: Some of these applications include the separation of humans from nature, and the propensity of governments and the public to allow ecological degradation in non-wilderness areas. Yet there are beneficial aspects to wilderness that contribute to a deeper understanding of human nature and our place in the world. Wilderness helps us to remember our wild and primal aspects that provide a connection with nature. In light of the perils and power of wilderness I offer a new, radical, inclusive, and expansive notion of wilderness that I name "dwellness." Dwellness is a normative ethical position where all areas upon the earth ought to be viewed by people in the same way as wilderness areas are currently viewed, but with some modifications. Unlike wilderness, dwellness includes humans within nature and also contains the idea of sustainable living practices. To support dwellness I turn to Martin Heidegger. / ABSTRACT: By identifying the world as a place where we dwell and in which we belong, we come to a more profound understanding of Being, or existence, in general and of our own particular modes of being. By learning to look at the world in this new, yet old, way we may then understand how important and central is the world, a mode of Being, to the existence and maintenance of our Being. Finally, I answer some possible objections to dwellness. These objections revolve around problems of industrial pollution (waste), which, under dwellness, would have to be considered natural. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.
