Photoshop图像处理中选区的选取

无论是作为Photoshop的初学者,还是专业的图形图片设计师,在运用Photoshop进行图像处理的时候经常用到各种各样的图片素材,而实际上往往只需要对图像的特定部分进行操作,这就需要从整张图片中选取所需要的区域,这就是选区。因此在用Photoshop进行创作时,我们基本上都要进行选择选区的工作。本文只综述在Photoshop中,如何选择选区。

文件处理中的工作流管理系统

流程活动中的大多数活动通常需要使用手工来实现工作流状态的频繁改变,这是工作流在控制、监测和优化方面的一个由来已久的老问题了,这个老问题现在可以通过使用一种新的信息系统来解决,即支持业务过程的工作流管理系统。工作流管理是业务过程逻辑的一个直接表现,它是通过计算机支持来完成管理的。文章讨论了处于一个组织内部的用于文件处理的工作流管理系统,该系统在该组织内部的不同地方被多个用户所使用。     

Ex ante contracting with endogenously determined communication plans

Summary. In this paper we introduce a new model of ex ante contracting for economies with asymmetric information to examine endogenously determined communication plans for information sharing in the interim stage. In contrast to the models used in previous research, in the present model agents negotiate not only on a contract of state contingent allocations but also on a communication plan, a set of rules describing how agents will reveal part of their private information at the interim stage to execute the trade contracts. We prove a result about the nested structure of the set of allocations implementable by various communication plans and establish the existence of core strategies for this cooperative game under various regularity conditions.

The joint influence of technology uncertainty and interorganizational interaction on external technology integration success

This paper empirically examines the acquisition of a technology from a source outside the firm and its incorporation into a new or existing operational process. We refer to this key activity in process innovation as external technology integration. This paper develops a conceptual framework of external technology integration based on organizational information processing theory and technology management literature. The primary hypothesis underlying the conceptual framework is that external technology integration will be most successful when the level of interaction between the source of the technology and recipient of the technology is appropriately matched, or fit, to the characteristics of the technology to be integrated. The conceptual framework also develops other hypotheses relating to contextual factors that may also influence the success of external technology integration. A cross-sectional survey methodology is employed to test the four hypotheses of the conceptual framework, with the results indicating strong support for the fit hypothesis and general support for the contextual hypotheses. The paper closes with a discussion of the implications of this study for both theory and practice.
