Chris Russell's research, sponsored by the Air Force Research Laboratory Human Effectiveness Directorate, demonstrated significant improvement of mission effectiveness using adaptive automation and the operator's mental workload in Uninhabited Combat Air Vehicle (UCAV) missions. His work is the first example of closing the loop between the human and the machine by using mental workload based on physiological signals from the operator to adapt the system. Implementation of his research is being demonstrated in a variety of applications, including the Uninhabited Combat Air Vehicle control workstation, Tactical Tomahawk Weapons Control System, and the Objective Force Warrior Program.

The purpose of this study was to investigate the structures, processes, and interactions of mentoring and other collaborative relationships underlying a network of support for candidates pursuing National Board Certification. The overarching question guiding the inquiry---how do veteran teachers construct and utilize a network of support in their efforts to achieve National Board Certification---was investigated through the following secondary questions: (a) For what purposes are individual relationships cultivated within a National Board candidate's support network? (b) What influences the development and use of individual relationships within a National Board candidate's support network? (c) How do National Board candidates structure individual relationships within their support network? (d) How do individual relationships within a National Board candidate's support network interact?. Utilizing grounded theory methodology, a substantive theory is presented to describe how National Board candidates in a school system utilized a network of support during their candidacies. The Core Network Model is initiated by the specific needs of the National Board candidates, but responds to both environmental and personal influences related to candidacy efforts. In response to these purposes and influences, candidates structure their individual relationships within a hierarchy of core and satellite relationships. These relationships variously meet through formal and informal structures. The interactions of the individual relationships, as suggested in the Core Network Model, occur within and between communities. However, these interactions are tempered by their proximity to one another and a shared purpose in the candidate achieving National Board Certification. The Core Network Model highlights the role of candidate self-initiative in constructing and utilizing a support network for National Board Certification. Yet, school building level supports, as perceived by the candidates, also play a part in assisting or hindering the network's overall development. A series of recommendations address development of the theory and implications for National Board Certification support.

This dissertation uses data on all U.S. employees at a large firm in the high technology industry over multiple years to examine the relationship between various forms of deferred compensation (performance bonuses and employee stock options) and voluntary turnover. In comparing the two forms of deferred compensation considered, employees that had outstanding stock options were less likely to voluntarily terminate than employees that received a performance bonus overall. Whether paying an employee in bonuses or stock options is a more cost effective retention tool for the firm depends on how employees value the stock options relative to the firm's costs. The higher the employee's risk aversion, the greater is the cost of stock options for the firm relative to the employee's valuation. For an employee with an average level of risk aversion, increasing retention by paying the employee an additional bonus is more cost effective than granting the employee additional stock options that achieve the same probability of retention over the four year option vesting period as the additional bonus. However, for lower levels of risk aversion, stock options may be more cost effective than bonuses.

Dragonflies are one of the most manueverable of the insect flyers. They are capable of sustained gliding flight as well as hovering, and are able to change direction very rapidly. Exactly how they use their wings to generate aerodynamic forces remains unknown. A new method was developed for solving 2D incompressible viscous flow problems [46] in order to numerically model the fluid response and forces generated by multiple flapping wings. This finite difference scheme uses the streamfunction-vorticity formulation on a regular grid, and handles multiple moving irregular boundaries. To test the usefulness of this model, dragonflies were tethered to a vertical force sensor and filmed using high-speed digital video. This allowed the correlation of specific wing kinematics to the vertical force generated, so that when these kinematics are modeled numerically the forces calculated can be compared with experiment. The results include detailed descriptions of two distinct wing kinematic patterns, out of four observed. These kinematics resemble motions described by previous researchers in free flight conditions except for the phase between the fore and hind wings. The forces calculated from applying the numeric method to a 2D approximation of these movements compare well to measured forces. The differences seen can be attributed to 3D effects and to the simplified wing cross-section used in the model. We show that wing inertia is a large component of the instantaneous forces experienced by a dragonfly, and that the dragonfly generates productive force during both the downstroke and the upstroke. The counter-stroking behavior seen in free flight is shown to require less power than the in-phase motion observed in the tethered dragonfly, while producing the same average vertical force. We also show evidence suggesting that during hovering flight wing rotation is passively driven by fluid forces, while during forward flight rotation at the end of the downstroke is actively driven by the dragonfly. Finally, the effectiveness of applying such a 2D model to the problem is examined, and suggestions are made for future research to improve modeling ability.

This dissertation details the results of a multi-year (2001-2004) study of settlement patterning on the periphery of the Postclassic Maya capital of Mayapan, Yucatan, Mexico. Ethnohistoric and archaeological evidence both suggest that the site was the capital of the last powerful Pre-Hispanic regional polity in the area. The apparently coerced resettlement of local elites and portions of the populations of provinces that came under Mayapan's control to its center led to a very rapid rise of the site and an equally rapid fissioning and depopulation when internal strife resulted in its demise. In contrast to earliest Classic Period political centers. Mayapan is a very large and dense settlement. The massive defensive walls surrounding the site are arguably the most formidable anywhere in Mesoamerica. The obvious differences in settlement patterning seem to reflect significant social changes taking place between the two major periods of Maya pre-history. Research reported in this volume includes mapping, test pitting and soil sampling of architecture encountered along eight survey transects extending 1 km in various cardinal directions from the city's roughly 9 km city wall. The study analyzed the form and function of all architecture recorded in this previously unexplored portion of the site. New data presented here suggest that some 17,000 people were present at the site, rather than the 12,000 person population estimate that has been widely used since 1962. The known site size more than doubled from 4.2 sq km to between 8.8 and 10.1 sq km. The site-wide spatial distribution and function of, residential settlement zones, economic production activities, the road system, administrative architecture and ritual architecture are all explored in detail. The results presented here and being generated by other ongoing research at the site by both INAH and Dr. Marilyn Masson of SUNY---Albany raise important questions about the scale of political complexity achieved by the polity centered at the site. The complexity, size and form of the city suggest that it may be the capital of a previously unappreciated Maya/Itza empire that co-existed with other better known Postclassic empires such as the Aztecs and Tarascans.

This study offers a paradigmatic shift in understanding the development of the biblical traditions about Egypt. It challenges the dominant scholarly view that the traditions about Egypt and the exodus are monolithic. It instead emphasizes the differing regional portrayals of Egypt, and especially highlights the contribution of the Transjordanian tribes to the Bible's portrait of Israel's history. The shift is afforded by an examination of the representation of Egypt in biblical texts that date from the eighth century B.C.E. or earlier. The most important texts analyzed are the golden calf stories in 1 Kings 12:25-33 and Exod 32, the oracles of Balaam in Numbers 22-24, and the Song of the Sea in Exodus 15:1b-18. The provenance of these and other biblical texts are established so that a picture emerges of the differing traditions about Egypt in Cisjordan Israel, Transjordan Israel, and Judah. In the north, an exodus from Egypt was celebrated in the Bethel calf cult as a journey of Israelites from Egypt to Cisjordan, probably without a detour eastward to Sinai and the wilderness. The exodus was envisioned in military terms as suggested by the nature of the polemic against the cult in Exodus 32, and the attribution of the exodus to the warrior Yahweh, Israel's own deity. In the east, it was a tradition of deliverance from Egypt that was celebrated, rather than the idea of a journey up from Egypt. This deliverance was associated with the head of the regional pantheon El. In the south, Egypt was also recognized as a major enemy of Israel, but the traditions there were not formulated in terms of an exodus event. Rather, the destruction of an Egyptian military force was commemorated. The dissertation seeks to relate the regional portrayals of Egypt to the broader picture of Syro-Palestinian history. It challenges the view that the biblical traditions about Egypt were invented in the exilic or post-exilic periods. It instead anchors them in the pre-exilic history of Israel, the Transjordan, and Judah, while acknowledging the transformative effect that the experience of exile had on the biblical memory of Egypt.

It has been argued that development of science knowledge is the result of social interaction and adoption of shared understandings between teachers and students. A part of understanding that process is determining how student reasoning develops in groups. Transactive discussion is a form of negotiation between group members as they interpret the meaning of their logical statements about a topic. More importantly, it is a form of discourse that often leads to cognitive change as a result of the interaction between group participants as they wrestle with their different perspectives in order to achieve a common understanding. The research reported here was a correlational study designed to investigate the relationship between the various forms of transactive discussion and learning outcome performance seen in an investigation involving 24 students in a middle-SES high school located in southwest Atlanta, Georgia. Pretest and posttest measures of genetics reasoning, as well as curriculum content test data, were used in this study. Group discussion was captured on videotape and analyzed to determine whether transactional discussion was present and whether or not it had an effect on learning outcome measures. Results of this study showed that participant use of transactive discussion played a role in development of reasoning abilities in the area of genetics. It is suggested that teachers should monitor classroom discourse for the presence of transactive discussion as such discourse plays a role in fostering performance outcomes.

People spend a large portion of their lives working, and everyone who works is influenced by their work and career experiences. Thus, the assessment of a person's current career status (satisfaction, interpersonal abuse, career worries, job involvement, work-home tension) can provide valuable diagnostic information for both the client and the career counselor. This study examined the effect of a career intervention---more specifically, the impact of the Career Attitudes and Strategies Inventory (CASI; Holland & Gottfredson, 1994) on career activity and job seeking. In addition to assessing the effects of the CASI on career development of clients in an experimental intervention, the research determines if there is a relation between CASI scores, career activities, and client worldview. It was found that experimental group participants---those completing the CASI---engaged in more passive career development or job search activities than control group participants. No significant difference was found between groups in active or problem related career development/job search activities. However, a treatment by age interaction was found and reflected that older treatment group participants reported less active career development activities than younger treatment group participants. The opposite was found among the control group. Hypothesized relationships between Job Satisfaction and Geographical Barriers and Interpersonal Abuse and Risk-Taking Style were not supported. A significant relationship was found between the CASI Family Commitment Scale and the Here and Now worldview of the Scale to Assess Worldview. Limitations and strengths of the current study as well as future directions for research are discussed.

Frazzled (Fra) is a highly conserved receptor expressed on the cell membrane, and it is important for several morphological processes, including cell migration, axon guidance, and adhesion. In addition to these functions, the vertebrate homologue of Fra, Dcc, also functions as a tumor suppressor that has a pro-apoptotic effect in the absence of its canonical ligand Netrin. In both invertebrates and vertebrates, the axon guidance cue Netrin interacts with the extracellular domain of Fra/Dcc to recruit cytoplasmic proteins and affect local cytoskeletal changes to promote axon growth across the midline. In addition, Fra functions independently of Netrin as a transcription factor. Fra is cleaved by gamma-secretase, which allows the Fra intracellular domain to enter the nucleus and activate transcription. Fra activates transcription of Commissureless, and endosome cycling receptor that is required to promote axon growth across the midline. However, whether this signaling mode of Fra is required in other tissue contexts outside of the nervous system is unknown. In Chapter 1, I introduce a subset of axon guidance genes and how they regulate gene expression in the nervous system as well as their known roles in reproductive tissues. In Chapter 2, I show that Fra is required in the fly ovary for egg chambers to progress through mid-oogenesis independently of Netrin, and this requires the transcriptional activation domain within the Fra intracellular domain. Interestingly, in contrast to the pro-apoptotic role that Dcc has in vertebrates, Fra has an anti-apoptotic role in the germline. In Chapter 3, I use a yeast-two hybrid screen to identify proteins that interact with the Fra intracellular domain, and test the DNA-binding proteins identified for a role in axon guidance and in the female germline. Finally, in Chapter 4 I discuss the implications of this work and potential future directions that would be exciting to explore.
