论总经理在ERP建设过程中的角色定位

中国企业的信息化成功与否,关键在于企业最高领导者能否把信息化应用上升到作为改造企业的发展战略,进而寻找有效的实施方式和改造方法.因此,信息化是“一把手”工程,企业总经理在实施过程的不同阶段,应该充当企业信息化的领头羊,应该是企业信息化战略实施的推动者、参与者.仅有企业管理手段的信息化,而没有企业最高层领导的管理思维、管理观念的信息化,这个企业就不是真正的信息化企业.

Assessing and Controlling Acquiescent Responding When Acquiescence and Content Are Related: A Comprehensive Factor-Analytic Approach

This article proposes procedures for assessing and controlling acquiescence in personality scales when acquiescence is related to the content that the scale intends to measure. Our proposal is comprehensive in that it can be applied to different item response formats fitted with response models that can be parameterized as factor-analytic models. In the calibration stage, our proposal makes joint use of a balanced scale and a set of markers for acquiescence, and consists of 2 sequential procedures: a direct semirestricted solution, and a restricted solution with minimal identification constraints. In the scoring stage, we discuss how the information given by the acquiescence–content relation can be used to obtain Bayes expected a posteriori scores. The robustness of the direct procedure is assessed both analytically and by simulation. A free, user-friendly program that implements the procedures proposed is made available. Practical issues of use and interpretation are discussed and illustrated with an empirical application.     

Domain Coloring and the Argument Principle

Abstract

The domain-coloring algorithm allows us to visualize complex-valued functions on the plane in a single image—an alternative to before-and-after mapping diagrams. It helps us see when a function is analytic and aids in understanding contour integrals. The culmination of this article is a visual discovery and subsequent proof of the Argument Principle, which relates the count of poles and zeros of a meromorphic function inside a contour to the accumulated change in argument of the function around the contour. Throughout, I offer connections to standard learning goals of courses in complex variables.     

费歇判别法在乳房癌诊断中的应用

研究了乳房肿瘤的分类问题，通过对500个已知肿瘤性质(良性或恶性)细胞核的显微图像的10个量化特征进行统计分析，利用费歇判别法，建立了费歇判别模型，给出了判别准则，对未知乳房肿瘤性质的病例进行了成功的诊断；最后对变量进行了合理的缩减．本方法具有良好的实用性和操作性．     

民族主义与二十世纪的战争

民族主义与20世纪的战争有不解之缘。但在不同时期、不同国家和不同类型的民族主义对战争所起的作用存在着重大差异：帝国主义各国民族主义的恶性膨胀导致了两次世界大战，使人类饱受了史无前例的战争浩劫；殖民地半殖民地的民族主义推动了席卷亚非拉的民族解放战争的广泛开展，打碎了西方的殖民体系，广大殖民地半殖民地纷纷取得民族独立；二战后第三世界的民族主义导致了战后频繁的地区冲突和局部战争，成为世界动荡、威胁世界和平的重要因素。

关于主体性教学中教师主导作用的再认识

主体性教学是现代教学改革的必然趋势，其中的许多观点对当前的课堂教学改革都有实际作用。从主体性教学的一些观点看，中学语文教学在教学理念、教学方法的某些方面还有待进一步改进。     

试论民事检察制度之完善

我国现行民事检察制度之具体运用体现在民事诉讼法确立的检察监督制度,限制了检察权在民事诉讼领域的有效行使,远远不能适应市场经济条件下对保护国家利益、社会公益及保证诉讼公正的要求.完善民事检察制度应根据我国实际情况,拓宽检察监督的范围,增加民事检察监督的方式.     

Antecedents to psychosocial environments in middle school classrooms in Taiwan

This study investigated gender differences in students' perceptions of their psychosocial environment and related variables. Analyses of data collected from 644 middle school students reveal that there were significant differences in boys' and girls' perceptions, in favor of girls. Ten academic background variables were examined. Multiple regression results identified, in addition to gender, school membership, attendance, time spent doing homework, students' academic expectations, course grade, and course content as significant variables for all students, accounting for 31% of the variance in environment. There were gender-related disparities for the variables involved. While time spent doing homework, students' academic expectations, course grade, and course content had significant effects on both boys and girls' environments, school membership and time spent in watching TV had effects only on girls' perceptions. Educational implications of the findings are also discussed in the article. This revised version was published online in July 2006 with corrections to the Cover Date.
