The Impacts of Using Augmented Reality to Support Aircraft Maintenance

The United States Air Force (USAF) expends significant resources to address the rise in aviation mishaps derived from an overworked, understaffed maintenance community, and high operational environment. Currently, paper-based technical orders (T.O.) are utilized by maintainers to accomplish aircraft inspections, servicing, and maintenance tasks. As technology advances, many civilian agencies have begun to leverage augmented reality (AR) to improve organizational proficiency. This research seeks to identify if the inclusion of AR within aircraft maintenance will positively or negatively affect maintenance task accuracy and completion time. A single variable randomized complete block design (RCBD), within-subject design of experiment (DOE) asses the differences between a treatment group (AR-enabled T.O.) contrary to the control group (paper-based T.O.). Results conclude AR-enabled T.O.s designed from the AF perspective will reduce simple task errors, but will not impact total task completion time. Differentiation from prior findings, application specificity, will impact AR effectiveness and utilization within the organization employed. Additionally, experimental research revealed the need to address current AF infrastructure barriers before implementation of the technology within the organization

Evaluation of learning transfer outcomes of a Certified Occupational Safety Specialist (Coss) training course

The purpose of this study was to generate a “transfer of training” assessment of a Certified Occupational Safety Specialist (COSS) certification training course provided by the Alliance Safety Council, a non-profit organization which provides COSS training throughout the United States targeting individuals who work in the safety and health field that coordinate corporate safety and health plans for their companies. This course consists of a five day, forty hour in-class course designed to build competencies in the field of safety with specific learning outcomes. This study described graduates of the COSS training on selected personal and professional demographic characteristics, determined what variables influenced a graduate’s ability to transfer training within the workplace, and assessed the degree to which graduates of this training engaged in transfer of training activities in their respective workplaces. This paper makes recommendations regarding potential future research efforts designed to further examine COSS participation and sponsorship, barriers to transfer of training, and the impact of transfer of training on an organization’s safety performance. Finally, this paper provides feedback to COSS program designers, instructors, related practitioners

Partnering for Formation in Ministry: A Descriptive Survey of On-Site Field Education Mentoring

A theological field education internship is not simply busy work for a seminary student or cheap labor for the church or organization where the student intern is ministering. Instead, involvement in a theological field education experience is a fundamental element in the intentional development of a future minister leader. A great internship opportunity can place a seminary student in an environment where God can work through the student in the lives of other people.  Further, a great internship can provide an environment where God can work in the seminary student's own life to expand a greater understanding of God's call, deepen the student's Christ-like character, and further develop ministerial competencies

Context-Adaptive Management of Drivers’ Trust in Automated Vehicles

Automated vehicles (AVs) that intelligently interact with drivers must build a trustworthy relationship with them. A calibrated level of trust is fundamental for the AV and the driver to collaborate as a team. Techniques that allow AVs to perceive drivers’ trust from drivers’ behaviors and react accordingly are, therefore, needed for context-aware systems designed to avoid trust miscalibrations. This letter proposes a framework for the management of drivers’ trust in AVs. The framework is based on the identification of trust miscalibrations (when drivers’ undertrust or overtrust the AV) and on the activation of different communication styles to encourage or warn the driver when deemed necessary. Our results show that the management framework is effective, increasing (decreasing) trust of undertrusting (overtrusting) drivers, and reducing the average trust miscalibration time periods by approximately 40%. The framework is applicable for the design of SAE Level 3 automated driving systems and has the potential to improve the performance and safety of driver–AV teams.U.S. Army CCDC/GVSCAutomotive Research CenterNational Science FoundationPeer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/162571/1/Azevedo-Sa et al. 2020 with doi.pdfSEL
