Power-Based Arbitrary Decisional Actions in the Resolution of MIS Project Issues: A Project Manager's Action Research Perspective

As a management information systems (MIS) project manager and an action researcher, the author examined, over time, the influence on information system development (ISD) of the informal sociopolitical organizational actions. The paper reports two cases of action research findings concerning the effect on ISD project implementation processes of power-based arbitrary decisional actions in bureaucratic environments. The research focused on the relationship of such unilateral actions to the interconnected subprocesses of deliberate and conscious attempts by the ISD project members to define and resolve system implementation issues. A suggested conceptual framework for the issue-resolution processes (IRP's) and obstacle-coping processes (OCP's) is based on the author's IRP/OCP-related behavioral constructs and theoretical models dealing with soft-systems issues, especially appreciative system theory and soft-systems methodology, and innovative flexible, "complementarist" (Sinn, 1998) or pluralist problem-solving approaches.

Banach空间中m-增生型非线性方程组的迭代解

设E为任意实Banach空间,TD(T) E→E是具有有界值域的一致连续m-增生算子,其中T的定义域D(T)是E的一个子集.本文证明了当T不是Lipschitz连续时,对于任意给定的f∈E,含误差项的Ishikawa和Mann迭代方法(由刘立山教授提出，见J.Math.Anal.App.194(1995),114－125)强收敛于m-增生型非线性方程组x+Tx＝f的唯一解.本文改进和扩展了近期Chidume，Ding，Liu和Ostilike的许多相关结果．

Computer analysis of arbitrary reinforced concrete cross-section under bieccentric load

The computational aspects of the problem of ultimate strength analysis of arbitrary reinforced concrete cross-sections under normal force and biaxial bending are considered. The cross-section secant stiffness derived here in sures the convergence of the solution for the equilibrium equations in any load case. The stress-strain relations of con crete and reinforcements are expressed in terms of the piece-wise continuous cubic polynomials. The coefficients of the cross-section equilibrium equations are evaluated numerically by applying the integration rules proposed by Rieckmann and Sommerfield. The present approach is demonstrated through several examples.
