Software system safety

Software itself is not hazardous, but since software and hardware share common interfaces there is an opportunity for software to create hazards. Further, these software systems are complex, and proven methods for the design, analysis, and measurement of software safety are not yet available. Some past software failures, future NASA software trends, software engineering methods, and tools and techniques for various software safety analyses are reviewed. Recommendations to NASA are made based on this review

Design of a Computerized Procedure for Commercial Loan Analysis

The purpose of this study is a discussion of existing techniques of commercial loan analysis and to develop a computer model to assist loan officers in the evaluation of credit decisions. The intent of the model is to present an orderly and compact arrangement of the financial data used to analyze loan requests. The model uses a IBM/CPS system. This system provides the model with real time conversational inputs and outputs, combined with the speed and power of computers. It was found that there is not one correct method or technique for evaluation of loan requests, but a computer model can be developed that can provide assistance to the loan officer. The model produces financial outputs to help analyze the creditworthiness of a borrower. Although the model does produce outputs that help to evaluate the repayment capability of the firm, the model does not and should not concern itself with the actual credit decision. The procedures developed provides the loan officer with the flexibility that they need to make accurate credit decisions. By computerizing financial data needed in loan decisions, the loan officer is able to spend more time on those activities at which only men are adept.Financ

Test program review

This paper provides a review of test program requirements and operations applicable to space instruments systems. The Apollo Lunar Surface Experiment Package (ALSEP) test program is summarized and then evaluated in terms of performance vs overall effectiveness in Section 2. Section 3 discusses the basic requirements for the definition of typical space instrument verification activities and indicates tradeoffs to be considered in the analysis and planning stages, and in the test operations phases of hardware development. In the final section, three classes of payloads are defined and verification tasks and documentation requirements are evaluated for these payloads in terms of cost effective program implementation. ALSEP is used in this case study as typical of the most critical payload for high reliability performance and life.prepared by D. Perkins, D. Fithian ; approved by B. Rusky.Introduction -- ALSEP test program -- Typical program requirements -- Recommendations -- Conclusion

The Influence of Workplace Stressors, Resources and Perceptions on Work-to-Family Spillover: An Application of the Double ABCX Model

Changes in the American workforce have raised concern over the interface between family and work. The responsibilities and frustrations of the work domain frequently spill over to the family domain and vice versa. The purpose of this research has been to investigate the influence of workplace stressors, resources, and perceptions on subsequent negative work-to-family spillover. The theoretical direction for the study stems from a modified application of McCubbin and Patterson\u27s double ABCX model, which fits well into the larger spillover perspective. The data for the study came from 1992 National Study of the Changing Workforce [NSCW). A subsample of respondents who worked full-time, lived with another family member, and were not self-employed was used for the analysis. The final sample consisted of 598 respondents. The findings suggest that work-co-family spillover is more common for women than men. However, the workplace stressor and resources in this study had less direct influence on work-co-family spillover for women than for men. In shore, an adequate explanation of work-to-family spillover is likely more complex for women than for men. The findings also generally supported the theoretical model. That is, workplace stressors, workplace resources, and family perceptions generally had an effect on work-co-family spillover. Interestingly, formal workplace resources, such as family-friendly programs, had only a small effect on work-to-family spillover. However, exploring spillover from a family-co-work direction would have possibly yielded different results. Informal resources had only modest direct effects on work-to-family spillover, but indirect effects were practically important. General perception had the strongest direct effect on work-to-family spillover for both men and women

Machine intelligence and robotics: Report of the NASA study group

Opportunities for the application of machine intelligence and robotics in NASA missions and systems were identified. The benefits of successful adoption of machine intelligence and robotics techniques were estimated and forecasts were prepared to show their growth potential. Program options for research, advanced development, and implementation of machine intelligence and robot technology for use in program planning are presented
