Dimensional analysis

Dimensional analysis is a useful tool which finds important applications in physics and engineering. It is most effective when there exist a maximal number of dimensionless quantities constructed out of the relevant physical variables. Though a complete theory of dimensional analysis was developed way back in 1914 in a seminal paper by Buckingham, systematic procedures necessary to construct a sufficient number of dimensionless quantities have become available only recently. In this article, we describe with an example the steps involved in the Szirtes algorithm which is fairly simple to understand and quite straightforward to use.     

Governing Boards in Public Higher Education Institutions: A perspective from the United States

Governing boards have a long tradition and prominent role in U.S. higher education. The diversity of institutional types, and thus governing boards, represents a multifaceted tapestry of functions, roles, and responsibilities. This paper will attempt to define the parameters of public higher education governing boards in the USA and offer critical insights into their degree of effectiveness. It is the author’s position that both positive and negative lessons can be learned through an examination of these public governing boards in the USA. The recent emergence of university boards in Europe is examined and their characteristics are compared against the characteristics of public and private boards in the USA.

     

A comparison of Dabrowski's overexcitabilities by gender for American and Korean high school gifted students

The differences between US (Ohio) gifted and talented high school students and South Korean gifted and talented high school students on the Overexcitabilities Questionnaire II (OEQ II) were investigated. The OEQ II was administered to 227 Ohio identified gifted and talented high school students (M = 88, F = 139) and to 341 high school students from four specialized high schools (one for science, one for foreign language, and two for the arts) in Seoul, Korea (M = 117; F = 224). Multiple analysis of variance by gender and country revealed that Korean males and females scored higher in psychomotor OE and that US males and females scored higher in imaginational OE. No differences were found in intellectual OE, emotional OE, or sensual OE.     

Competencies for port and logistics personnel: An application of regional human resource development

Human resource development for regional strategic industries is an emerging emphasis for the development of industries that have growth potential. This article identifies competencies and expertise levels needed by port and logistics industry personnel, a sector that has growth potential in Busan, South Korea. The research consisted of expert interviews to develop a competency survey. Six competency clusters and 16 sub-competencies were developed. This research was useful in the development of an educational program and suggests ways in which regional human resource development (RHRD) can be used.

中国城市人均GDP差异影响因素的分析

在阐明当前我国城市人均GDP水平差异现状的基础上，通过多元回归分析，揭示造成这种差异的原因。结论是目前我国城市人均GDP水平差异很大，资本投入是影响城市人均GDP的决定性因素，其次是城市的产业结构。外资只对东部和大中城市有明显影响。人口规模与城市人均GDP之间关系不大，在大城市组甚至呈负相关。分析表明转变我国粗放的经济增长方式已经非常迫切，片面“做大”城市规模对提高城市的经济发展水平于事无补。

Identifying Children with Persistent Developmental Dyscalculia from a 2‐min Test of Symbolic and Nonsymbolic Numerical Magnitude Processing

Developmental dyscalculia (DD) is a mathematical learning disability that occurs in around 5%–7% of the population. At present, there are only a handful of screening tools to identify children that might be at risk of developing DD. The present study evaluated the classification accuracy of one such tool: The Numeracy Screener, a 2‐min test of symbolic (Arabic numerals) and nonsymbolic (dot arrays) discrimination ability. A sample of 222 children who demonstrated persistent deficits (n = 55), inconsistent deficits (n = 51), or typical performance (n = 116) on standardized tests of math achievement over multiple observations was tested. The Numeracy Screener correctly classified children in all three groups. Notably, the symbolic condition has greater sensitivity in discriminating children with persistent DD from the other two groups. Screening tools that assess early numeracy skills may be promising for identifying children at risk for developing severe mathematical difficulties.     

Is There a Need for Transcendental Arguments in Discourse Ethics?

In this essay, James Scott Johnston examines Jürgen Habermas's transcendental justification of his discourse theory of morality. According to Johnston, the application of Habermas's theory to educational issues often assumes that this justification is a cogent one. However, if the theory is to provide reasoned and appropriate guidance for educators, the justification of discourse ethics requires closer examination. Johnston argues that Habermas's so‐called “weak” transcendental approach is in fact unsustainable because it fails to reconcile two conflicting schools of philosophical thought: Kant's transcendental idealism and George Herbert Mead's social pragmatism. Johnston concludes that a more plausible justification of the discourse ethical project can be achieved by rejecting Habermas's Kantianism and appealing solely to Mead's social pragmatic conception of rationality.
