Morris: The Cold Driver: Driving Performance Under Thermal Stress

Title of Thesis: The Cold Driver: Driving Performance Under Thermal Stress

Type: Thesis Proposal

Abstract:
Exposure to cold environments can impact complex task performance and increase cognitive and physiological error in response to thermal stress. Critically, the task of driving a vehicle requires the use of calibrated mental and physical actions to be conducted safely without error. Few studies have examined the effects of cold stress on driving performance and none have explored the potential for advanced driver safety systems to detect error. Active vehicle safety systems which monitor dangerous driving behavior due to drowsiness have been research and developed, though technology associated with thermal stressed driving error is unexplored. The current study aims to examine the effects of cold stress by way of skin cooling on driving simulator performance, and evaluate vehicle behavior metrics for possible dangerous driving detection systems. Driving under cold stress is expected to result in systematic vehicle behavior and driving performance error which can be utilized for future safety system development.

Abstract:
Service members of the United States military occupy jobs that are unlike most in the exposure to exceptional stress and the potential for life-threatening and traumatic on-the-job experiences. Because of the nature of the job tasks and duties, many soldiers are vulnerable to developing mental health problems. Even more problematic, many soldiers experiencing mental health symptoms are not getting the treatment they need. The present study examined how social support can influence a soldier’s decision to engage in treatment and stay in treatment. More specifically, the study examined the unique influence of family and friends, fellow unit members, and leaders in the soldier’s decision to seek treatment, as well as different supportive behaviors from leaders that affect treatment seeking and retention. Using data from active duty soldiers surveyed at two time points, results indicated that support for treatment seeking is related to whether or not soldiers seek treatment through positively affecting their attitude toward treatment. Support from family members and friends was found to be most related to attitude and treatment decisions. These relationships were further moderated by functional impairment, where the effect of support on treatment seeking through attitude was strongest for those with problems causing low or moderate impairment. In terms of leader supportive behaviors, instrumental leader support was rated as the most influential to soldiers’ treatment decisions. Lastly, in terms of treatment retention, initial evidence was found that support from family members and spouses may influence whether or not soldiers drop out of treatment. Results from this study are intended to be informative for application in enhancing social support resources that are most effective for getting soldiers into treatment and increasing retention.

Cook: Correlational Study of the Handoff Communication Process as a Result of Variation in Staffing Levels

Title: Correlational Study of the Handoff Communication Process as a Result of Variation in Staffing Levels

Committee: Dr. Lee Gugerty (Chair), Dr. David Neyens (Co-chair), Dr. June Pilcher

When: April 22, 2014 @ 1:30
Where: Brackett 122

Abstract: The patient handoff is an intricate process that takes on many forms within the healthcare domain. One incredibly common, yet complex handoff is that from the Emergency Department (ED) to the respective floor unit for the extended care of a patient upon hospital admission. While the specifics of the protocol for this process vary between institutions, the importance of a successful handoff for patient safety is universal. This study will examine the effects of the variation in staffing levels on the communication handoff process based on the time of day at which the process occurs.

Altenhoff: Perceiving Soft Tissue Break Points in the Presence of Friction

Perceiving Soft Tissue Break Points in the Presence of Friction

Committee: Dr. Chris Pagano (chair), Dr. Tim Burg, Dr. Ben Stephens, Dr. Rich Pak

Abstract: In minimally invasive surgery (MIS), surgeons face several perceptual challenges due to the remote interaction with the environment, such as distorted haptic feedback through the instruments due to friction produced from the rubber trocar sealing mechanisms at the incision site. As a result, surgeons sometimes unintentionally damage healthy tissues during MIS due to excessive force. Research has demonstrated that useful information is available in the haptic array of soft tissues, which allows novices to successfully perceive the penetration distance remaining until a material will fail based on displacement and reactionary forces of simulated tissues using a haptic invariant, Distance-to-Break (DTB). Attunement and calibration training will be used in the current study to investigate whether observers are able to identify material break points in nonlinear compliant materials through haptic force application, while ignoring haptic stimulation not lawfully related to the properties specifying DTB, including friction. A pretest, feedback, posttest, and transfer-of-training phase design will be used, allowing participants to probe four virtually simulated materials at varying levels of friction: no friction, low friction, and high friction in the first experiment, and pull the simulated tissues in the second experiment to investigate if perception of DTB generalizes to other tasks used in MIS.

Stanyar: IMPACT OF PHYSICAL AND PSYCHOSOCIAL WORKPLACE HAZARDS ON EMPLOYEE HEALTH: AN IRISH TALE OF CIVIL SERVANT WORKERS

IMPACT OF PHYSICAL AND PSYCHOSOCIAL WORKPLACE HAZARDS ON EMPLOYEE HEALTH: AN IRISH TALE OF CIVIL SERVANT WORKERS
Obesity, mental health problems, and absenteeism are both economic and health burdens for employers and employees. Research suggests that physical and psychosocial hazards in the workplace contribute to health risks and health problems among employees. There is a need for researchers to examine how exercise, diet, and age interact with the negative effects of workplace hazards upon health. Hypotheses 1a through 3b predicted that physical and psychosocial workplace hazards would negatively impact body mass index (BMI), general mental health, and sickness absences. Further, hypotheses 4a through 9b predicted that exercise and diet would buffer stress from occupational hazards upon BMI, mental health, and sickness absences. Finally, hypotheses 10a through 11b predicted that age would act as a moderator between occupational hazards and employee health outcomes. A sample of 16,651 civil servant workers from the Northern Ireland Civil Service Workforce were examined. The data was split into two groups based on salary; senior level pay grade and lower level pay grade. The results confirmed hypotheses 1a, 1b, 3a, 3b, 11a, and 11b for the lower level pay grade, but failed to support hypotheses 2 and 4a through 10b. Additionally, the results confirmed hypotheses 1b for the senior level pay grade; however the results failed to confirm hypotheses 1a and hypotheses 2 through 11b. Theoretical and organizational implications are discussed.

Robertson: The Agreeableness of Conscientiousness: A Facet Level Examination of Personality, Interaction, and Curvilinearity on the Citizenship Behavior and Task Performance Relationship

Title: “The Agreeableness of Conscientiousness: A Facet Level Examination of Personality, Interaction, and Curvilinearity on the Citizenship Behavior and Task Performance Relationship”

Abstract: Recent research has highlighted that the relationship between organizational citizenship behavior and task performance is nonlinear such that the occurrence of task performance behaviors will decrease as more time and resources are devoted to organizational citizenship behaviors. This occurs because of the restrictions of resource allocation theory which posit that employee resources are finite and limited, so there will be some trade-off between engaging in various performance behaviors. The current study seeks to examine the potential moderating effect of certain facets of agreeableness, conscientiousness, and their interaction. Agreeableness is thought to moderate the relation between individually focused citizenship (OCB-I) and task performance by accelerating the decrease in performance; conscientiousness is thought to moderate the relation between organizationally focused citizenship (OCB-O) decelerating the decrease in performance. Three way interactions of personality and citizenship will also be examined. Additionally, the mediating effect of job satisfaction will be analyzed because it has been shown to be important in forming the relationship between dispositional characteristics and performance behaviors.
