Several Theoretical Problems Concerning PhD Candidate＇s Education in the Area of Modern Management Accounting

This paper consists of five parts： Part one： ＂Modem Management Accounting Has Been Confronting with Serious Crises＂ points out that accompanied by the management systems shifting from material basis to human （knowledge） basis, and the IT developing rapidly, the management accountants＇ services that continue to remain at original level would become no useful very soon. Part two： ＂PhD Candidates＇ Education Would Be Essential to Develop Their Disciplines＇ Scholarship＂ explores the main peculiarities of PhD candidates＇ education, and why the development of PhD Candidates＇ Creative thinking should be permeated through the doctoral programs from the beginning to the end, so as to make them possible to develop their disciplines＇ scholarship. Part three： ＂The Quality Requirements of PhD Candidates in the Area of Modern Management Accounting＂ explains in detail why the development of management accounting should shift from the quantitative perspective to humanistic perspective so that management accountants can play an important role in the process of decision-making on the basis of employing their comprehension thinking that is a kind of humanistic thinking. This paper views this direction of development is essential to promote management accountants＇ self-impendence and self-vitality and to eliminate their crises cited above as well in the new historical era. Part Four： ＂The Key Points of the Doctoral Program in Modem Management Accounting＂ explores how to implement a doctoral program successfully in order to develop PhD Candidates＇ Creative Thinking, carrying forward academic democracy emphasized. Part Five： ＂Conclusion＂ points out how the topics discussed in this paper are linked up each other, and why and how the new developing tendency of management accounting is essential to make this discipline more suitable to the development of knowledge economy.

Anomalies in the Foundations of Ridge Regression

Errors persist in ridge regression, its foundations, and its usage, as set forth in Hoerl & Kennard (1970) and elsewhere. Ridge estimators need not be minimizing, nor a prospective ridge parameter be admissible. Conventional estimators are not LaGrange's solutions constrained to fixed lengths, as claimed, since such solutions are singular. Of a massive literature on estimation, prediction, cross–validation, choice of ridge parameter, and related issues, little emanates from constrained optimization to include inequality constraints. The problem traces to a misapplication of LaGrange's Principle, unrecognized singularities, and misplaced links between constraints and ridge parameters. Alternative principles, based on condition numbers, are seen to validate both conventional ridge and surrogate ridge regression to be defined. Numerical studies illustrate that ridge regression as practiced often exhibits pathologies it is intended to redress.     

Leadership,Creative Problem‐Solving Capacity,and Creative Performance: The Importance of Knowledge Sharing

This article presents two studies that examine whether leader supportive behaviors facilitate knowledge sharing and employee creative problem‐solving capacity, thereby enhancing creative performance. The findings from both studies indicate that leader supportive behaviors are directly and indirectly related, through both internal and external knowledge sharing, to employee creative problem‐solving capacity. In addition, creative problem solving was related to the two dimensions of creative performance—fluency and originality. However, a test of the mediation model indicated that creative problem solving only mediated the relationship between internal knowledge sharing creative performance and originality. These findings highlight the complex process by which leaders facilitate both internal and external knowledge sharing and employee creative problem‐solving capacity, thereby improving employee creative performance.
