Application of Automatic/Controlled Processing Theory to Training Tactical Command and Control Skills: 1. Background and Task Analytic Methodology
No full text In this paper we briefly highlight relevant laboratory research that provided the theoretical and empirical underpinnings for the development of a task-analytic training methodology. The actual task-analytic methodology, developed to decompose tasks performed to support tactical command and control (C2), air-weapons controller missions, is briefly discussed. The present paper provides the necessary background for the actual application of the methodology. The details of the direct application are presented in a companion paper by Eggemeier, Fisk, Robbins, and Lawless (1988). </jats:p
Automatic and Control Processing Approach to Interpreting Vigilance Performance: A Review and Reevaluation
No full text The present paper discusses vigilance phenomena in terms of the automatic/control processing theory (Schneider and Shiffrin, 1977) of attention and human information processing. Fisk and Schneider (1981) interpreted vigilance decrements within the automatic/control process framework and discussed system design implications as well as training methods for vigilance environments. Recent results concerning the effects of various stressors on automatic and control processes are presented. Taken as a whole, these results from vigilance, alcohol intoxication, heat stress, and mental workload experiments highlight why, when addressing sustained attention issues, it is critical to understand the mode of information processing (i.e., automatic/control) available to perform the task. </jats:p
Re/making men and women for the race: Coeducation, respectability and black student leadership at Fisk University, 1924-1970
No full textThis dissertation analyzes the relationship between student self-determination, the existence of competing ideologies of respectable race leadership and the transformation of coeducation at Fisk University between the 1924 and 1970. Throughout, a major focus of this dissertation is to trace how ideologies of race leadership were transformed by student dissent at Fisk. As a result, this research is concerned with analyzing students’ redefinition and negotiation of race leadership at the college. Throughout, the author asserts that Fisk students used self-determination in order to transform models of race leadership at the college.
Specifically, this manuscript provides a critical interrogation of the influence of New Negro, civil rights and Black Power philosophies on the self-determination of students and their notion of what constituted respectable race leadership between 1924 and 1970. This research is more than just a history of student dissent. “Re/Making Men and Women for the Race: Coeducation, Respectability and Black Student Leadership at Fisk University, 1924-1970,” in addition, highlights the complicated and contested meaning given to the historic and contemporary role played by Black colleges in preparing students for race leadership in the African American community.
Student dissent at Fisk posed a major challenge to the organization and governance of academic and student affairs at the college. The Fisk student strike of 1924, the Civil Rights and Black Power protests of the 1960’s and other examples of student self-determination created an alternative model of race leadership espoused by Fisk men and women. Throughout the history of the institution, students adopted a model of race leadership that stressed autonomy and a belief in Black people’s ability as professionals and as race leaders to advocate social equality on behalf of their community.U of I OnlyAuthor filed a 2-year extension request

On processing line graphs: understanding aging and the role of spatial and verbal resources
No full textThe objective of this research is to explore high-speed analog-to-digital converters (ADCs) using silicon-germanium (SiGe) heterojunction bipolar transistors (HBTs) for wireless digital receiver applications. The stringent requirements of ADCs for the high-performance next-generation wireless digital receiver include (1) low power, (2) low cost, (3) wide input signal bandwidth, (4) high sampling rate, and (5) medium to high resolution. The proposed research achieves the objective by implementing high-performance ADC's key building blocks and integrating these building blocks into a complete sigma-delta analog-to-digital modulator that satisfies the demanding specifications of next-generation wireless digital receiver applications. The scope of this research is divided into two main parts: (1) high-performance key building blocks of the ADC, and (2) high-speed sigma-delta analog-to-digital modulator. The research on ADC's building blocks includes the design of two high-speed track-and-hold amplifiers (THA) and two wide-bandwidth comparators operating at the sampling rate > 10 GS/sec with satisfying resolution. The research on high-speed sigma-delta analog-to-digital modulator includes the design and experimental characterization of a high-speed second-order low-pass sigma-delta modulator, which can operate with a sampling rate up to 20 GS/sec and with a medium resolution. The research is envisioned to demonstrate that the SiGe HBT technology is an ideal platform for the design of high-speed ADCs.M.S
Emotion and motion: age-related differences in recognizing virtual agent facial expressions
No full textTechnological advances will allow virtual agents to increasingly help individuals with daily activities. As such, virtual agents will interact with users of various ages and experience levels. Facial expressions are often used to facilitate social interaction between agents and humans. However, older and younger adults do not label human or virtual agent facial expressions in the same way, with older adults commonly mislabeling certain expressions. The dynamic formation of facial expression, or motion, may provide additional facial information potentially making emotions less ambiguous. This study examined how motion affects younger and older adults in recognizing various intensities of emotion displayed by a virtual agent. Contrary to the dynamic advantage found in emotion recognition for human faces, older adults had higher emotion recognition for static virtual agent faces than dynamic ones. Motion condition did not influence younger adults' emotion recognition. Younger adults had higher emotion recognition than older adults for the emotions of anger, disgust, fear, happiness, and sadness. Low intensities of expression had lower emotion recognition than medium to high expression intensities.M
