Economists and management “scientists” tend to adopt a rationalistic, “black box” approach to the treatment of technological innovation, with decisions to invest in innovation being viewed as climactic acts and with the significant impact of risk and uncertainty often being disregarded. This paper examines an alternative analytical perspective: that a least the early development of technological innovation is a process of incremental decision making where managerial responses are affected by the consequences of previous decisions and by alterations in external information. The development of the “poromeric” Porvair discussed here illustrates the considerable risks that have to be borne when undertaking radical innovation, and the nature of the uncertainties, the interdependency between them and the manner in which they persist, in this case even beyond the commercialization of the new product. 相似文献

The internal consistency and split-half reliability of the Teacher Stress Inventory (TSI) was investigated based on data provided by 3,478 teachers, representing 22 individual and two aggregate samples from six states. The data indicate for both the strength and frequency dimensions that the TSI is highly reliable in terms of both its regular and short-form length, and that the two short forms are highly correlated with one another. 相似文献

The Fourth Edition of the Stanford-Binet and the WISC-R were compared as instruments for assessing the intellectual strengths and weaknesses of students classified as learning disabled in the primary and secondary grades. Results found only a 3.28-point difference (p≥.0001) between the S-B Composite score and the WISC-R Full Scale score. Correlations between the four broad areas of the S-B and the three scales of the WISC-R ranged from .494 (S-B Abstract/Visual Reasoning with WISC-R Verbal) to .920 (S-B Composite with WISC-R Full Scale). All correlations were found to be significant. Implications of the research findings were discussed. 相似文献

The alternate-forms and alpha reliabilities of the Teacher Stress Inventory were investigated based on the responses of two groups of 138 teachers. Reliability estimates ranged from .43 to .94 for the TSI subscales and .71 to .94 for the TSI whole scale, indicating high stability and equivalence for the stress factors across immediate, one-day, one-week, and two-week intervals using two different TSI short forms. Between-forms correlations were larger for the immediate sample than they were for the interval samples. Short-form TSI alphas ranged from .76 to .90. 相似文献
