Validity of the X-factor computation methods and relationship between the X-factor parameters and clubhead velocity in skilled golfers

The purpose of this study was to assess the validity of the X-factor computation methods and to examine whether direct relationships exist between the X-factor parameters and the clubhead velocity in a group of skilled male golfers (n = 18, handicap = ? 0.6 ± 2.1). Five driver trials were captured from each golfer using an optical motion capture system (250 Hz). Two plane-based methods (conventional vs. functional swing plane-based) and one Cardan rotation-based method (relative orientation) were used to compute select X-factor (end of pelvis rotation, top of backswing, ball impact (BI), and maximum), X-factor stretch (stretch and maximum stretch), and X-factor velocity (BI and maximum) parameters. The maximum clubhead velocity was extracted and normalized to golfer's body height to eliminate the effect of body size. A one-way repeated MANOVA revealed that the computation methods generated significantly different X-factor parameter values (p < 0.001). The conventional method provided substantially larger X-factor values than the other methods in the untwisting phase and the meaningfulness of select X-factor parameters generated by this method was deemed questionable. The correlation analysis revealed that the X-factor parameters were not directly related to the maximum clubhead velocity (both unnormalized and normalized).     

What Does the No Child Left Behind Act Mean to Early Childhood Teacher Educators?: A Call for a Collective Professional Rejoinder

This article is a call to become more critically aware of the new law commonly referred to as No Child Left Behind Act, which was put into effect in 2002 in the United States. The article is also an invitation to early childhood educators worldwide to engage in a dialogue that raises several questions: (a) How does such legislation affect early childhood educators and teacher preparation programs?; (b) How might teacher educators react and respond to the new law as they continuously practice informed decision-making about teacher preparation that is socially responsible? In view of these questions, it is a hope that we can see the initiation of nationwide dialogue regarding the issue of the No Child Left Behind Act. Primarily, how does the new law affect teacher educators and teachers? It is inevitable for us to be united and politically informed to prevent further scrutiny of questionable politically and economically driven educational practices in the United States, not to mention “test-heavy” evidence-based education reform.     

The Meaning of Social Inclusion for People with Disabilities in South Korea

This study sets out to examine and understand the meaning of social inclusion for people with disabilities, as constructed by people with disabilities themselves. Focus group interviews with 34 people who have physical impairments, cerebral palsy, or hearing or visual impairments were conducted for the study. Using the data obtained from these interviews, the interviewees’ various definitions and perceptions of social inclusion were analysed and four meaning categories for social inclusion were identified: excluded/segregated, present, participating, and actively participating. The findings of this research can be used as foundational material in the development of disability policies and the improvement of social services to better enable full social participation and social inclusion for people with disabilities.     

A sequence-based filtering method for exhibition booth visit recommendations

As exhibitions are known to play important roles in marketing and sales promotion, the exhibition industry has grown significantly not only in the exhibition event size and frequency but also in the number of participating firms and visitors. While the challenge in assessing economic returns from exhibitions is being studied, it is agreed that the eventual success of an exhibition resides largely in its ability to meet the visitors’ needs. Visitors use an exhibition as a source of information when searching for products or services. Though an exhibition provides an information-rich environment, however, visitors often get lost in the abundance of information. A specialized recommender system can be a good solution to information overload as it can guide visitors to right exhibition booths and help them collect necessary information. Traditional collaborative-filtering recommender systems, however, use only customers’ rating or purchase records so that they do not capture exhibition visitors’ temporal visit sequences and dynamic preferences. Moreover, due to the computation overhead, they cannot generate real-time recommendation in ubiquitous environments for exhibitions. In order to overcome these drawbacks, this study proposes a booth recommendation procedure that takes into consideration not only booth visit records but also visit sequences. Experiment results show that the proposed procedure achieves higher recommendation accuracy, faster computation, and more diversity than a typical collaborative-filtering recommender system. From the results, we conclude that the proposed booth recommendation procedure is suitable for real-time recommendation in ubiquitous exhibition environments.     

STUDENT RIGHTS, CLARENCE THOMAS, AND THE REVOLUTIONARY VISION OF EDUCATION

A bstract .  In his concurring opinion to the 2007 U.S. Supreme Court decision, Morse v. Frederick , Justice Clarence Thomas argues that the Tinker decision, which granted students constitutional rights in public schools, should be overturned on originalist grounds. In this essay, Bryan Warnick, Bradley Rowe, and Sang Hyun Kim make the case that Thomas's originalist analysis is inconclusive. Instead of looking at court decisions relating to public education starting in the middle of the nineteenth century to establish original meaning, as Thomas does, they argue that a better strategy involves an analysis of educational ideas circulating closer to the time of constitutional ratification. Using this strategy, the authors show that many prominent educational writers (a) believed that it was important for students to learn to act independently and to value their constitutional rights, and (b) believed that students learn best by imitating civic examples. These two ideas work together in early American educational thought to imply that schools should exemplify the sort of respect for self-governance and individual rights that is present in the larger constitutional order. Thus, Warnick, Rowe, and Kim argue that there are originalist reasons for supporting student rights that Thomas ignores. In the end, this analysis not only highlights the limitations of originalist interpretative strategies, it also reminds us, more broadly, of a way to reconcile liberty and order in civic education.     

An institutional analysis of an e-government system for anti-corruption: The case of OPEN

E-government is increasingly being used to improve transparency in the government sector and to combat corruption. Using institutional theory as an analytical perspective, this study documents and evaluates the development of an anti-corruption system called OPEN (Online Procedures ENhancement for civil application) in the Seoul Metropolitan Government. Incorporating three distinctive (yet interrelated) dimensions of institutionalization (regulatory/coercive, cognitive/mimetic, and normative), and four anti-corruption strategies embedded in the system, this study investigates how an e-government system for anti-corruption in a local government has evolved and become a prototype of a national system to be used for the same purpose. The findings show that in implementing OPEN, a system for anti-corruption, the regulatory dimension was most effective, and (as in many IS implementations) strong leadership was crucial to its success.     

韩国的司书公务员制度

韩国公务员职级制度包括司书职源于1949年制定的《公务员聘用令》。司书公务员根据所属单位以不同方式聘用,但在聘用程序上遵守同一原则和标准。韩国司书公务员的职级体系按照九级至五级的顺序运营,从2007年至今在政府组织工作的司书公务员人数估计达到4,000人以上。近来,由于公务员名额减少使得司书公务员在聘用方面存在一定的困难,但在增建公共图书馆和《学校图书馆振兴法》的影响之下,公共图书馆的司书及司书教师数量将有所增加。     

中古汉语否定副词"莫"的历史演变及其动因

否定副词"莫"从上古发展到中古,在功能上发生了调整:魏晋南北朝时期否定副词"莫"用例明显增加,不仅可以用来表示一般否定,而且可以表示禁止否定.这一调整是内外因相互作用的结果. "莫"之所以能够发展成为否定副词,最根本的原因就是由于无定代词"莫"具备了转化成为否定副词的内在因素:语义上,无定代词"莫"意为"没有谁"或"没有什么"; "莫"的句法位置有可能引起重新分析;副词的修饰限制作用进一步促进了否定词"莫"的产生.
