论违约与精神损害赔偿

对于违约是否包括精神损害赔偿,学界有不同的观点,通说认为不予赔偿。本文通过分析传统的观点,并进行比较法上的考察,认为在违约责任中可以适用精神损害赔偿。同时就如何建构违约的精神损害赔偿制度提出了建议。     

空间相关非平稳地震荷载作用下的大坝风险分析

坝体风险性研究具有十分重要的意义。文章提出了在空间相关非平稳地震荷载作用下,不同破坏模式下的大坝风险分析系统分析方法。首先采用人工生成空间相关非平稳地震动时程和Mazars混凝土损伤模型,通过对混凝土重力坝的坝头、上游折坡面以及建基面等处的损伤值及其抗滑稳定系数的研究,然后推导了大坝溃口宽度以及相应的溃口流量随时间的变化规律,根据溃口时间和流量变化推出了溃坝后的生命损失以及财产损失,最后进行了算例分析。通过计算结果可以看出,所提出的模型能够考虑大坝的风险发生的各个过程,并能够较全面的描述大坝的风险。更多还原

心理契约破坏对企业员工组织公民行为的影响

为探讨情感承诺在心理契约破坏对不同类型组织公民行为影响的中介作用。本研究对来自杭州、苏州与常州的12家企业的330名员工进行了问卷调查,结果显示：①心理契约破坏对组织公民行为存在显著负性影响,并且心理契约破坏对指向个人的组织公民行为（OCB—I）的影响更大;②心理契约破坏对指向组织的组织公民行为（OCB—O）的影响是通过情感承诺来传递的,而对指向个人的组织公民行为（OCB—I）的影响则是直接作用。

上海地区海塘堤顶越浪风险分析

为了解上海地区海塘抵御风浪越顶的能力,对海塘堤顶越浪进行了风险分析。选取典型海塘结构,采用蒙特卡罗法,对各区域的堤顶越浪概率进行了计算,指出近年建设的海塘堤顶越浪风险较小,而崇明三岛地区的越浪风险较大。并通过对影响堤顶越浪的各相关特征参数作敏感性分析,得出高潮位的参数变化是影响海塘堤顶越浪安全性最显著的因素,而适当提高海塘堤顶的安全加高值对减少堤顶越浪风险具有显著的效果。     

NUMERICAL SIMULATION OF LEVEE BREACH FLOWS UNDER COMPLEX BOUNDARY CONDITIONS

Levee or dam failure can cause a significant disaster in most cases. A good prediction of the flood process especially in a real complex terrain is necessary for working out emergency plans for levee or dam breaches. Numerical simulations of levee or dam breach flow were carried out often with constant flow parameters and in relatively simple channels rather than in natural rivers with complex boundaries. This article presents our dedicated studies on the 2-D numerical model of levee or dam breach hydraulics with finite difference schemes. The good performance of the model is demonstrated by comparisons with the theoretical solution of an idealized dam-break flow over a frictionless flat rectangular channel. The model is also validated through its stability and conservation properties. The model is applied to simulate the flood propagation under complex boundary conditions, and the unsteady flood process in a river and in the dry floodplain with a complex bed terrain simultaneously. Furthermore, with respect to engineering practice, the numerical solutions can give special guidance to the effects of parameters such as the flood depth at different sites and the inundated area at different time periods after the levee breach and the travel time of the flood waves, which may be very important for practicing engineers in an efficient flood management.     

Do promises matter? An exploration of the role of promises in psychological contract breach.

Promises are positioned centrally in the study of psychological contract breach and are argued to distinguish psychological contracts from related constructs, such as employee expectations. However, because the effects of promises and delivered inducements are confounded in most research, the role of promises in perceptions of, and reactions to, breach remains unclear. If promises are not an important determinant of employee perceptions, emotions, and behavioral intentions, this would suggest that the psychological contract breach construct might lack utility. To assess the unique role of promises, the authors manipulated promises and delivered inducements separately in hypothetical scenarios in Studies 1 (558 undergraduates) and 2 (441 employees), and they measured them separately (longitudinally) in Study 3 (383 employees). The authors’ results indicate that breach perceptions do not represent a discrepancy between what employees believe they were promised and were given. In fact, breach perceptions can exist in the absence of promises. Further, promises play a negligible role in predicting feelings of violation and behavioral intentions. Contrary to the extant literature, the authors’ findings suggest that promises may matter little; employees are concerned primarily with what the organization delivers.
