The justness and the efficiency of contracts will depend on the effectiveness of contract discipline. This disciplin will be most effective when contractors have a good range of alternatives to choose from and when they ca make those choices on the basis of good information about the alternatives. This notion of contract disciplin is used in this paper as the basis for reviewing the coherence and effectivenss of judicial attempts to control con tracting behavior in the United Kingdom. It is suggested that the legal analysis of contract needs to be reorientate toward an exploration of the sources of contract indiscipline in the many highly imperfect markets in the real world 相似文献

This paper focuses on the psychology of social change and social justice. Specifically, we focus on subordinates’ reactions to new and old supervisors, and we argue that in evaluating these different types of supervisors, subordinates may rely on prior fair or unfair experiences as temporal frames of reference. We further propose that a result of these frames of reference may be that previous fairness experiences have a bigger impact on subordinates’ reactions to subsequent neutral communications when an old rather than when a new supervisor is the source of that communication. Findings of two empirical studies indeed show that subordinates who had had fair experiences with a particular supervisor reacted more positively toward subsequent neutral messages when the communication was coming from the old supervisor rather than from the new supervisor. Subordinates who had had unfair experiences, however, reacted more negatively toward the communication when the source was the old rather than the new supervisor. Some evidence was also found for contrast effects such that people who react to a new supervisor may react more positively with the neutral demand from this authority figure when they have earlier experienced unfair as opposed to fair treatment by a different supervisory agent. These findings were obtained on subordinates’ satisfaction with the supervisors’ communication and their acceptance of the supervisor. Finally, we discuss the implications for the psychology of social change and social justice. 相似文献

Improved detection of forensic evidence by combining narrow band photographic images taken at a range of wavelengths is dependent on the substance of interest having a significantly different spectrum from the underlying substrate. While some natural substances such as blood have distinctive spectral features which are readily distinguished from common colorants, this is not true for visualization agents commonly used in forensic science. We now show that it is possible to select reagents with narrow spectral features that lead to increased visibility using digital cameras and computer image enhancement programs even if their coloration is much less intense to the unaided eye than traditional reagents. The concept is illustrated by visualising latent fingermarks on paper with the zinc complex of Ruhemann's Purple, cyanoacrylate-fumed fingerprints with Eu(tta)(3)(phen), and soil prints with 2,6-bis(benzimidazol-2-yl)-4-[4'-(dimethylamino)phenyl]pyridine [BBIDMAPP]. In each case background correction is performed at one or two wavelengths bracketing the narrow absorption or emission band of these compounds. However, compounds with sharp spectral features would also lead to improved detection using more advanced algorithms such as principal component analysis. 相似文献
