The Effects of Alternative Presentation Formats on Biases and Heuristics in Human Decision Making

The Effects of Alternative Presentation Formats on Biases and Heuristics in Human Decision Making

Date: May 1996
Creator: Van Dyke, Thomas P. (Thomas Peter)
Description: The purpose of this research was to determine whether changes in the presentation format of items in a computer display could be used to alter the impact of specific cognitive biases, and to add to the knowledge needed to construct theory-based guidelines for output design. The problem motivating this study is twofold. The first part of the problem is the sub-optimal decision making caused by the use of heuristics and their associated cognitive biases. The second part of the problem is the lack of a theoretical basis to guide the design of information presentation formats to counter the effects of such biases. An availability model of the impact of changes in presentation format on biases and heuristics was constructed based on the findings of a literature review. A six-part laboratory experiment was conducted utilizing a sample of 205 student subjects from the college of business. The independent variable was presentation format which was manipulated by altering the visual salience or visual recency of items of information in a visual computer display. The dependent variables included recall, perceived importance, and the subjects' responses to three judgment tasks. The results clearly demonstrate that changes in presentation format can be used to alter ...

Job Satisfaction Among Women Accounting Educators

Job Satisfaction Among Women Accounting Educators

Date: May 1996
Creator: Vest, Cynthia Ann
Description: A national survey was conducted to investigate job satisfaction among women accounting educators at four-year college and universities in the United States. The purpose of the study was to determine if differences existed among women accounting educators at research, doctoral, master's, and baccalaureate institutions in three areas relating to job satisfaction: levels of job satisfaction, individual sources of job satisfaction, and structural sources of job satisfaction. Also, the relationships among these three areas of job satisfaction were examined. A stratified random sample of 755 women accounting educators was selected from the population of 1,519 women. A mailed questionnaire was used to collect data. A total of 495 (66%) questionnaires were returned. Women accounting educators expressed satisfaction with co-workers, supervision, and work. They were neutral regarding satisfaction with pay and dissatisfied with promotion opportunities. A difference was detected between satisfaction with pay and type of institution. Differences were found between individual sources of job satisfaction and type of institution. The differences were attributable to education level and the personality characteristics of conscientiousness and openness. Differences were detected between structural sources of job satisfaction and type of institution. Academic rank, salary, tenure, institutional resources, and job functions accounted for the differences. Significant ...

Library CD-ROM LAN Performance and Patron Use: a Computer Simulation Model

Library CD-ROM LAN Performance and Patron Use: a Computer Simulation Model

Date: May 1996
Creator: Xia, Hong
Description: In this study, a computer simulation model for library CD-ROM LAN systems was created. Using this model, the system optimization problems were examined. The simulation model imitated the process of the actual decision variables changing their values and generated the corresponding results. Under a certain system environment, if the values of decision variables are changing, the system performances are getting changed also. This study investigated these relationships with the created model. The system users' interarrival time, service time, and other relevant data were collected on randomly selected days in a university library. For data collection, both of the observation and the system automatic metering software were used. According to the collected data, a discrete events simulation model was created with GPSS/H. The simulation model was proven valid and accurate by a pilot test and by the calculation with queuing theory. Statistical tests were used for data comparison and analysis. In addition, animation technique was used to show the simulation process by using Proof Animation. By this technique, the simulation process was monitored on the screen.

Rollback Reduction Techniques Through Load Balancing in Optimistic Parallel Discrete Event Simulation

Rollback Reduction Techniques Through Load Balancing in Optimistic Parallel Discrete Event Simulation

Date: May 1996
Creator: Sarkar, Falguni
Description: Discrete event simulation is an important tool for modeling and analysis. Some of the simulation applications such as telecommunication network performance, VLSI logic circuits design, battlefield simulation, require enormous amount of computing resources. One way to satisfy this demand for computing power is to decompose the simulation system into several logical processes (Ip) and run them concurrently. In any parallel discrete event simulation (PDES) system, the events are ordered according to their time of occurrence. In order for the simulation to be correct, this ordering has to be preserved. There are three approaches to maintain this ordering. In a conservative system, no lp executes an event unless it is certain that all events with earlier time-stamps have been executed. Such systems are prone to deadlock. In an optimistic system on the other hand, simulation progresses disregarding this ordering and saves the system states regularly. Whenever a causality violation is detected, the system rolls back to a state saved earlier and restarts processing after correcting the error. There is another approach in which all the lps participate in the computation of a safe time-window and all events with time-stamps within this window are processed concurrently. In optimistic simulation systems, there is ...

Women Who Survived Childhood Sexual Abuse: Do Their Coping Strategies Vary by Personality Type as Measured by the Myers-Briggs Type Indicator?

Women Who Survived Childhood Sexual Abuse: Do Their Coping Strategies Vary by Personality Type as Measured by the Myers-Briggs Type Indicator?

Date: December 1996
Creator: Jahn, Linda
Description: Through a phenomenological qualitative approach, this study examined possible differences of introverted versus extraverted adult female survivors of childhood sexual abuse with regard to the coping mechanisms they chose. Preference modalities of introversion and extraversion were measured by the Myers-Briggs Type Indicator and data was collected through a semi-structured interview designed by the researcher. The interview contained questions about the 21 subjects' perceptions of their abuse and the ways in which they coped. Specific coping mechanisms included but were not limited to eating disorders, alcohol and/or drug abuse, high risk behavior, depression, anxiety, and somatic complaints. Results indicated that for both groups, the degree to which each of the individual coping mechanisms was used congregated at the level of "a driven pattern of behavior lasting for at least 7 days" or "on-going use resulting in severe problems". Extraverts showed higher percentages of severe use of the six coping mechanisms than did introverts. Depression was the most frequently used coping mechanism of both the introverts and the extraverts. Introverts showed higher percentages of stopping the use of eating disorders, alcohol/drug abuse, high risk behavior, and depression. Extraverts had higher percentages of discontinued use of anxiety and somatic problems. Introverts reported more ...

A Model Curriculum for the Graduate Preparation of Collegiate Basketball Coaches

A Model Curriculum for the Graduate Preparation of Collegiate Basketball Coaches

Date: December 1996
Creator: Evans, Marc S.
Description: The purposes of the study were (a) to examine selected areas of knowledge perceived by collegiate basketball coaches as essential for inclusion within a masters degree curriculum for collegiate basketball coaches, then (b) based upon these findings, to construct a model curriculum for the masters degree preparation of collegiate basketball coaches. A survey instrument, Questionnaire on the Areas of Knowledge Essential to Collegiate Basketball Coaches, was constructed and mailed for the purpose of collecting data from NCAA coaches. There were 252 instruments returned (58%). The coaches were asked to respond to topics which they perceived to belong within a graduate curriculum for intercollegiate coaches. The areas of knowledge were extrapolated from the 1995 National Association for Sport and Physical Education National Standards for Athletic Coaches. Chi-square goodness-of-fit tests and paired t-tests were performed on the data. Major findings of the study led to the conclusion that the areas of knowledge (a) training, conditioning, and nutrition; (b) skills, tactics, and strategies; and (c) teaching and administration mean rankings were not significantly different from one another but were significantly different from mean rankings from all other areas of knowledge. The areas of knowledge (d) social/psychological aspects of coaching; and (e) professional preparation ...

The Affects of Religiosity on Anomie

The Affects of Religiosity on Anomie

Date: August 1996
Creator: Wilson, Dwain R.
Description: This study explores the relationship between religion and anomie. The theoretical framework of Durkheim and Merton was used to suggest the hypothetical relationship between the two variables: as religiosity increases, anomie decreases. A secondary analysis was conducted using the 1991 General Social Survey (GSS). The GSS is one of the largest annual surveys conducted by the National Opinion Research Center. There were 1517 adult respondents composing the 1991 cross-national sample. Questions measuring both the belief and action dimensions of religion were used to measure respondents' level of religiosity. Questions from the Srole Scale of Anomia were used to measure respondents' level of anomia. Durkheim's theory that religion functions to integrate individuals into the larger society and therefore diminish levels of anomie was not supported with this data. While the lack of significant findings did not support the theory, neither did it disprove it. The hypothetical inverse relationship between class and anomie was supported with this data. Another hypothetical relationship, that of the most religious, women experience less anomie than men, was also not supported due to the lack of a significant relationship among the primary variables. Continued use of comprehensive and large scale surveys such as the General Social Survey ...
