透视中国古代雕塑的艺术特色

中国古代雕塑有独特的艺术特色。它的形成与中国古老的哲学有直接的联系。它主要受儒、释、道思想的影响。在中国古代文化背景的影响下，中国古代雕塑融功能美、意念美，形式美于一体，具有极强的浪漫主义色彩；在造型方面写实中带夸张，重类相，重写意；同时中国古代雕塑多种表现手法融于一体。

Retracted: On a Patrol Problem

Retraction: The following article from Teaching Statistics, ‘On a Patrol Problem’ by Mohammed Ageel, published online on 8 June 2007 on Wiley Online Library (onlinelibrary.wiley.com), has been retracted by agreement between the author, the current and immediate past journal Editors, Paul Hewson and Roger Johnson, the Trustees of Teaching Statistics and Blackwell Publishing Ltd. The retraction has been agreed due to unacknowledged overlap with ‘A Patrol Problem’ by Alan Levine, published in Mathematics Magazine, vol. 59, no. 3, pp. 159–166 (1986).     

Is Moodle a Platform to Decolonise the University Curriculum? Lecturers’ Reflections

Abstract

This article presents the results of an interpretive case study of three lecturers teaching a physical science module. The purpose of the study was to explore the lecturers’ reflections on their understanding of the Modular Object-Oriented Dynamic Learning Environment (Moodle) as a platform to decolonise the university curriculum. Purposive, with convenience, sampling identified the three most accessible lecturers. An emailed reflective activity, one-on-one semi-structured interviews, and Moodle observations were utilised for data production. Inductive and deductive processes were used to ensure guided analysis of the produced data. The article argues that the Moodle learning management platform (LMP) has the potential to decolonise the university curriculum. The study concluded that the lecturers reflected well in all curriculum signals based on their informal, formal and personal LMPs in order to address all the needs. Consequently, the study recommends that lecturers understand the curriculum signals of each Moodle platform, before teaching and learning take place, in order to to decolonise the university curriculum.

The development that leads to the Cloud Computing Business Framework

The Cloud Computing Business Framework (CCBF) is proposed to help organisations achieve good Cloud design, deployment, migration and services. There are four key areas to be addressed: (i) Classification; (ii) Organisational Sustainability Modelling (OSM); (iii) Service Portability and (iv) Linkage. Each area's focus is described, and we explain how each fits into the CCBF and work altogether. The process that leads the CCBF is supported by literature, case studies, where examples in each CCBF key area are used to illustrate its effectiveness and contributions to organisations adopting it. CCBF has been used in several organisations offering added values and positive impacts.     

The probability of winning break points in Grand Slam men's singles tennis

Abstract

The probability of winning games of tennis has been modelled in terms of the probability of the server winning an individual point. These models are based on the assumptions of stationarity of the point and interdependence. Stationarity is the assumption that the outcome of tennis points is not influenced by the game score at the beginning of the point. The purpose of the current investigation was to compare the outcomes of tennis points during break points and non-break points using data from 528 men's singles tennis matches from all four Grand Slam tournaments in 2008 and 2009. The retrospective probability of the receiver winning a point was 0.42 ± 0.23 during break points which was significantly greater than the 0.38 ± 0.10 during non-break points (P < 0.001). This, in turn, led to players creating significantly more break points than expected (P < 0.001) and breaking serve more frequently than expected (P < 0.001) for the points won when receiving serve. This is evidence that stationarity cannot be assumed and that models of winning tennis games may need to be enhanced to address improved receiver performance during break points.     

Learning from demonstrations: the role of visual search during observational learning from video and point-light models

In this study, we examined the visual search strategies used during observation of video and point-light display models. We also assessed the relative effectiveness of video and point-light models in facilitating the learning of task outcomes and movement patterns. Twenty-one female novice soccer players were divided equally into video, point-light display and no-model (control) groups. Participants chipped a soccer ball onto a target area from which radial and variable error scores were taken. Kinematic data were also recorded using an opto-electrical system. Both a pre- and post-test were performed, interspersed with three periods of acquisition and observation of the model. A retention test was completed 2 days after the post-test. There was a significant main effect for test period for outcome accuracy and variability, but observation of a model did not facilitate outcome-based learning. Participants observing the models acquired a global movement pattern that was closer to that of the model than the controls, although they did not acquire the local relations in the movement pattern, evidenced by joint range of motion and angle-angle plots. There were no significant differences in learning between the pointlight display and video groups. The point-light display model group used a more selective visual search pattern than the video model group, while both groups became more selective with successive trials and observation periods. The results are discussed in the context of Newell's hierarchy of coordination and control and Scully and Newell's visual perception perspective.
