ILR Impact Brief - Deconstructing Absenteeism: Satisfaction, Commitment, and Unemployment
[Excerpt] Group attitudes about satisfaction and commitment are negatively associated with absenteeism and interact in predicting absenteeism at the unit level. The effects are particularly strong in areas where jobs are plentiful but fade away where jobs are scarce. In other words, higher levels of absenteeism in a work group are associated with lower levels of job satisfaction and organizational commitment in labor markets with low unemployment, and vice versa. Organizational commitment is the crucial factor: absenteeism is higher in work units with low levels of commitment regardless of the level of satisfaction. Group norms about absenteeism and other contextual factors, such as work processes, contribute to the variance among work units. Satisfaction and commitment are not related to changes in absenteeism over time
The NASA aircraft icing research program
The objective of the NASA aircraft icing research program is to develop and make available to industry icing technology to support the needs and requirements for all-weather aircraft designs. Research is being done for both fixed wing and rotary wing applications. The NASA program emphasizes technology development in two areas, advanced ice protection concepts and icing simulation. Reviewed here are the computer code development/validation, icing wind tunnel testing, and icing flight testing efforts
