Reactions to Skill Assessment: The Forgotten Factor in Explaining Motivation to Learn

This study examined the effects of trainees’ reactions to skill assessment on their motivation to learn. A model was developed that suggests that two dimensions of trainees’ assessment reactions – distributive justice and utility – influence training motivation and overall training effectiveness. The model was tested using a sample of individuals (N = 113) enrolled in a truck driving training program. Results revealed that trainees’ who perceived higher levels of distributive justice and utility had higher motivation to learn. Training motivation was found to significantly predict several measures of training effectiveness. Trainees’ performance on the pre-training assessment and trait goal orientation exhibited direct and interactive effects on their reactions to the skill assessment. Implications of these findings for future research on reactions to skill assessments are identified along with the practical implications for the design and conduct of training needs assessment

Development of a Physiologic In-Vitro Testing Methodology for Assessment of Cervical Spine Kinematics

In-vitro biomechanical testing has been critical in the design and evaluation of spinal surgical instrumentation, however determination of realistic physiologic loading levels has proven difficult outside of the in-vivo setting. Unconstrained pure moment testing combined with the hybrid testing method is currently the gold standard test protocol for evaluation of motion preservation technology and adjacent level effects. Pure moment testing is well suited for making relative comparisons between treatments, but is currently not based on or representative of in-vivo spine motion, bringing the clinical relevance into question. The human cervical spine supports substantial compressive load in-vivo arising from muscle forces and the weight of the head. However, traditional in-vitro testing methods rarely include compressive loads, especially in investigations of multi-segment cervical spine constructs. Therefore, a systematic comparison of standard pure moment testing without compressive loading versus published and novel compressive loading techniques (follower load, axial load, and combined load) was performed. To achieve a pure moment test, a robot/UFS testing system was programmed with hybrid control, which combined load and displacement control to overcome the limitations of either control methodology alone. A follower load system was developed with actively controlled linear actuators and integrated into the robot/UFS testing system’s control algorithm. Thorough investigation of the integrated system ensured that the pure moment assumption was upheld and enabled characterization of the kinetics resulting from the application of follower load. In contrast, axial load was applied perpendicular to superior most vertebral body using the robot end-effector; it did not maintain the pure moment assumption resulting in alterations of the segmental motion patterns. The pure moment testing protocol without compression or follower load was not able to replicate the typical in-vivo segmental motion patterns throughout the entire motion path. Axial load or a combination of axial and follower load was necessary to mimic the in-vivo segmental contributions at the extremes of the extension-flexion motion path. It is hypothesized that dynamically altering the compressive loading throughout the motion path is necessary to mimic the segmental contribution patterns exhibited in-vivo—a novel concept that will be explored in future investigations

Lost Wax: An Exploration of Bronze Sculpture in Senegal

The goal of this Independent Study Project was for the researcher to develop an in-depth understanding of the techniques involved in the production of bronze sculpture via a short apprenticeship at the foundry at the Village des Arts in Dakar, Senegal. The researcher also sought to gain an understanding of the cultural context of the medium, including its history and social and economic significance through formal and informal interviews with artists and visits to various art galleries and workshops. Over the course of the ISP period, five works of art were produced by the researcher at the foundry. The researcher sought to produce works that reflected the themes, styles, subjects and motifs most often explored by bronze sculpture in Senegal
