走向消费伦理——致金惠敏(2007年9月21日)

从评价性的角度考察消费文化,其价值有两方面的含义:首先是它与经济价值的创造有关;其二是它与一般价值问题的联系.这两个方面相互关联.消费需要靠生产来维持,而生产若是要维持挥霍性的消费,则可能带来严重的环境灾难,这同时也就是人类的灾难.在消费中提倡一种对自然、对地球家园的负责任的"消费伦理",换言之,唤醒消费者的责任意识,于是便提上了当今消费文化研究的议事日程.     

Experience and reality in religious education

A central task of religious education is to show how the puzzlements to human intelligence and the experiences that are associated with spirituality, are compelling in relation to our development as human beings. There are always more theories than objects or events to be explained, and while the spiritual ‘data’ that gives rise to our puzzlements and experience is elusive and meagre, the supply of literature, teaching, ritual and other forms of articulation is torrential. To understand the nature of religious education we need firstly to ask about the nature of spiritual experience itself at its broadest level and then to identify and co-ordinate the kinds of material that will sensitise pupils to this experience and help them to articulate it. This should provide a basis for evaluation of the material against the context of their own life experiences. In this respect religious education is no different in structure to other areas of the curriculum.     

Slow thinking and deep learning: Tversky and Kahneman's taxi cabs

This article is based on classroom application of a problem story constructed by Amos Tversky in the 1970s. His intention was to evaluate human beings' intuitions about statistical inference. The problem was revisited by his colleague, the Nobel Prize winner Daniel Kahneman. The aim of this article is to show how popular science textbooks can serve as a source for rich classroom activity, with a little care in the implementation by teachers. Kahneman describes the problem as ‘standard’ and answers using a fixed point number. I describe how I have encouraged my students to challenge the certainty of this assertion by identifying ambiguities that are left unexplained in the story. This way, I claim to stimulate individuals to indeed move towards Thinking, Fast and Slow, the title of Kahneman's book.     

The effects of barbell load on countermovement vertical jump power and net impulse

The aim of this study was to examine the effects of barbell load on countermovement vertical jump (CMJ) power and net impulse within a theoretically valid framework, cognisant of the underpinning force, temporal, and spatial components. A total of 24 resistance-trained rugby union athletes (average ± SD: age: 23.1 ± 3.4 years; height: 1.83 ± 0.05 m; body mass (BM): 91.3 ± 10.5 kg) performed maximal CMJ under 5 experimental conditions in a randomised, counterbalanced order: unloaded, and with additional loads of 25%, 50%, 75%, and 100% of BM. Peak power and average power were maximised during the unloaded condition, both decreasing significantly (P < 0.05) as load increased. Net impulse was maximised with 75% of BM, which was significantly greater (P < 0.05) than the unloaded and 100% of BM conditions. Net mean force and mean velocity were maximised during the unloaded condition and decreased significantly (P < 0.05) as load increased, whereas phase duration increased significantly (P < 0.05) as load increased. As such, the interaction between barbell load and the underpinning force, time, and displacement components should be considered by strength and conditioning coaches when prescribing barbell loads.     

Characteristics and experiences of interns in strength and conditioning

Student coaches undertake internships to develop practical skills and gain experience to improve employability prospects. The characteristics of the coaches who undertake these internships, their experiences and the nature of the work being performed are currently unknown. The purpose of this study was to report the characteristics of strength and conditioning (S&C) coaches who have undertaken internships and their experiences during their respective placements. A total of 113 men and 6 women completed an online survey. Placements generally lasted 6–12 months (66%), were unpaid (93%) and took place at professional teams (63%). All respondents had a standard of experience prior to commencement (82%); a higher-education degree (bachelor’s degree 56%; master’s degree 18%) and others were qualified S&C coaches (16%). Activities consisted largely of coaching (47%), data collection (22%) and equipment set-up (25%) but lacked provision of appropriate training. Mentors were allocated to interns; however, often developmental objectives were not discussed, meetings were rarely documented, and in some cases, no meetings took place. This study suggests that internships offer worthwhile experiences and assistance in skill development to progress in S&C. However, clearer guidelines are required to define the responsibilities of employers and interns, to maximise these experiential learning opportunities and avoid the exploitation of willing students.     

A History of Ways of Seeing the Land: Environmental History at the National Museum of Australia

One of the distinctive features of the National Museum of Australia is the prominent role of environmental history in the Museum's programs and in its organizational structure. Environmental history is a field that operates best at the boundaries of science and the humanities, where the natural sciences and social history meet. The National Museum is one of few museums that facilitate this, drawing historians, geographers, archaeologists, earth scientists, and biologists into program development as members of the one curatorial and design team. This article discusses the advantages of environmental history as a strategic focus for the Museum, and looks at one of its major exhibitions.     

Young Children's Spatial Representations Developed through Exploration of a Desktop Virtual Reality Scene

Virtual Reality (VR) technology seems to offer the opportunity of designing 3D worlds and navigation activities which provide settings that are close to children's everyday experiences, capitalising on their enthusiasm for videogame-like technologies.This paper describes how different types of exploration of a VR scene by 6[emsp4 ]y-old children affected their performance in a series of spatial tasks. Individual children explored a desktop virtual world where we varied both the visual perspective on the VR scene (route vs. survey view) and the level of exploration control (active vs. passive movement). We measured children's knowledge of the spatial layout of the environment through their memory of objects' location in the virtual scene and through the analysis of their wayfinding abilities within the scene.The results indicate that children were able to develop and display different levels of allocentric knowledge about the virtual world depending on the way they had familiarized with it and on the characteristics of the task demands. This finding contributes to inform the design of VR technologies aimed at supporting or evaluating spatial abilities in children of this age.     

Who is using the .co.uk domain? Professional and media adoption of the web

This paper reports on a survey of 221 web sites chosen at random from a subset of the .co.uk area of the Internet. A breakdown of the types of business represented shows that whilst computing companies continue to have a sizeable presence on the web, certain other types of business now also have a relatively large number of sites. The survey found many media-related businesses and professional-based companies and practices, reflecting the increasing use of Information Technology in these areas but also the increasing knowledge about the Internet that is needed or helpful in many types of job. The results are consistent with general business use of the web in the UK still being in an experimental phase of web site creation by those who can rather than by those who should.
