Ernest R. Alexander 《Policy Sciences》1982,14(3):279-292
The design of alternative courses of action is an essential part of decision-making, but one which has been neglected in theory and practice. A pilot study of alternatives' design in organizations suggests that already in the design stage choice focuses on a few alternatives, highlighting the importance of design in affecting the quality of outcomes. Design may be search or creativity, or a blend of both. While search is probably a significant part of design, there may be a residue of basically irrational creativity. These observations suggest that design should be deliberately undertaken in decision- and policy-making, by intensifying search, developing and utilizing design methods, and providing organizational creativity-enhancing environments. 相似文献

The purpose of this study was to evaluate the efficiency of the Cozart RapiScan (CRS) drug test system for detecting opiates and cocaine in oral fluid. Oral fluid samples were collected using the Cozart RapiScan collection system from 358 donors who were receiving treatment for their addiction and were monitored for drug misuse. A further 103 oral fluid samples were collected from volunteer donors who were not drug users. The samples were analyzed in the laboratory using the two-panel Cozart RapiScan cartridge for opiates and cocaine and confirmed using gas chromatography-mass spectrometry (GC-MS). The samples were stored frozen at -20 degrees C until analysis by GC-MS. The overall accuracy of the CRS for both opiates and cocaine was 100%. Samples spiked at 50% above and below the cut-off consistently gave negative and positive results respectively. A total of 88 samples were positive for various opiates and 111 samples were positive for cocaine and/or its metabolites. The CRS for opiates and cocaine in oral fluid, using a cut-off of 30 ng/mL morphine or benzoylecgonine equivalents in neat oral fluid, had overall efficiencies of 98% and 99%, respectively, versus GC-MS. A series of potential adulterants of oral fluid were evaluated and shown not to alter the outcome of the test result. 相似文献

On the adolescent process as a transformation of the self 总被引:2,自引:0,他引:2
The purpose of this paper is to clarify and extend the psychoanalytic theory of adolescence. Three sources of data are used: biographical source material about Freud's adolescence, introspective accounts from the self-analysis of psychoanalysts, and other biographical vignettes and reports from the psychoanalytic literature. It is proposed that a change in the self emerges as the pivotal focus during adolescent development. An intense peer relationship serves to maintain narcissistic balance and the cohesion of the self. This allows deidealization of archaic parental imagoes and their transformation into newly internalized idealizations. The newly acquired idealizations consolidate into a stable ego ideal which eliminates the need for an alter ego relationship. The self-objects chosen for these new idealizations are related to the need to overcome specific disappointments in the archaic self-objects. The stability of the new ideals depends on the invulnerability of the idealized self-objects. Transient states of narcissistic disequilibrium manifest as turmoil.
