We examined significant human risk factors in aircraft maintenance technicians (AMTs) in the airline industry. We conducted an empirical study of Taiwan's airlines to determine these risk factors and to illustrate how a quantifiable evaluation approach integrates experts' opinions about the relative importance of risk factors. We developed an expert questionnaire and modified the human factors SHELL model to categorize the risk factors that we derived from the literature and the opinions of 107 senior experts. The empirical results showed that there are nine significant risk factors out of 77 preliminary and 46 primary risk factors. The results also provided support for the approach and model presented in this work, demonstrating that they are both strategically effective and practically acceptable. Analyzing and ranking the significant risk factors for AMTs in this fashion may help airlines to better focus on their major operational and managerial weaknesses in order to improve maintenance operations under the condition of limited resources. © 2009 Elsevier Ltd.

Air rages often happened in cabin service; both the trends of frequency and the extent of injury have been increased. Cabin crews' self-perceived ability of dealing with these unruly passengers, in nature, is a trait that cannot be observed and measured directly. Qualitative (focus group interview) and quantitative (questionnaire survey) methods of research were conducted to data collection and analysis. Additionally, apply the "Rasch model" to measure the "latent traits". Results showed that the most intractable passengers were "passengers who on poor mental conditions", then "A passenger who conceals or avoids providing important information", and "intoxication and passengers who inebriation on the plane". Then confer the respondents' ability and item difficulty by image concepts, and provide the same comparison basis, the difficulty about the self-perceived ability and the degree of difficulty of questions, and compared the differences in respondents abilities from different number of demographic characteristics. Practice recommendations are as followed: 1. Education before departure and error proofing for the passengers. 2. Acquisition of abroad previous experience to reinforce the local legal knowledge. 3. Establishment of sharable unruly passengers' database. 4. Re-training courses, reinforcement of ability to deal with emergency and emotional adjustment ability. 5. Enhance organizational support and continuing safety commitment. The study provided reference to airlines' on improve their education and training, crisis management mechanism on site, and service recovery strategies to reduce the cabin abnormal events and to promote flight safety.

Airport ramp workers are one of the defensive lines for aviation safety. Contents, subjects, and frequency of the safety training are very important for them to understand and increase their ability to reduce those risks. This study collected large amounts of aviation incidents, which were pieced together to restore original causes and facts by inference of fault tree analysis, with disciplinary methods to clarify hierarchy structures in "ground handling operational related accidents", and trace all possible mistakes. The relevant hazard factors are concluded to provide reference for questionnaire design, which could be used for curriculum planning for safety training. In order to ensure comprehensive content and careful design of the questionnaire, this study verified the reliability of data classification to ensure panelist consistency. Aiken content validity and Aiken homogeneity reliability are conducted to evaluate the appropriateness of the questionnaire and the screening items. The aggregation function by verbal evaluation was observed, and the severity of the attitudes conveyed by the interviewers during linguistic evaluations, and estimations of relative weights and order of items ensure the questionnaire's design. The results can be applied to ramp operations systems as a reference to minimize management costs, and assist business owners to ensure ramp workers have proper aviation safety orientation, appropriate arrangement of curriculum content, and hours for recurrent training.

This study used a post-Piagetian perspective to investigate the relation of dialectical thinking and creative performance in early adulthood. The modified version of the Social Paradigm Belief Scale was employed to measure the development of formal and dialectical thinking among 454 young adults, ages 23 to 40 years (M = 32.1, SD = 4.8). The Divergent Thinking Test estimated their creative performance. Scores on dialectical thinking were positively correlated and scores on formal thinking were negatively correlated with Divergent Thinking Test scores. Planned contrasts indicated that participants in the dialectical thinking group scored higher than did those in the formal thinking group on the six dimensions of the Divergent Thinking Test, i.e., Fluency, Openness, Flexibility, Originality, Elaboration, and Naming. Multiple discriminant analysis with a cross-validation examination showed the linear combination of scores on the six dimensions of creativity included in the Divergent Thinking Test discriminated between formal and dialectical thinking groups; this supported predictions about the relation between postformal thinking and creativity among young adults.
