The article uses auction data collected from the eBay internet site to examine the effect of various parameters on number
of bids and selling price of art. The article further uses an insight from the auction literature to gather evidence about
whether art on eBay is purchased for consumption or investment purposes. The article argues that the evidence found of a positive
relationship between the number of bids and the final price suggests that art sold on eBay is not, in general, investment
art.

The growth in professional learning is opening up many new opportunities for the application of e‐learning to the world of continuing professional development (CPD). CPD programmes require professionals to engage in annual programmes of professional development, and in some cases revalidation or recertification. To date, most of this activity has been off‐line. Increasingly, CPD requirements will be satisfied through the use of learning resources available on‐line or packaged into specially tailored e‐learning courses. Societies and professional associations – as the primary managers and coordinators of CPD programmes – are in a strong position to expand upon their existing Web‐based initiatives to deliver a new generation of e‐learning services to their members. 相似文献

This study attempted to analyse the cost-effectiveness of the Radio Education Teacher Training Project in Nepal. Cost-effectiveness is denned as a procedure by which the cost of alternative means of achieving a stated objective, or conversely, the effectiveness of alternative means for a given cost, are compared in a series of numerical indices. Comparison of the costs of the Radio Education Teacher Training Project and the Campus-Based Teacher Training Programme showed the latter to be much higher. 相似文献

A comparison was made of how Swedish adults evaluated politicalparties and the party leaders under three different survey methods:in-person interviews, telephone interviews, and mailed questionnaires.Both the party leaders and the parties were evaluated more negativelyby people responding on the mailed questionnaires. Telephoneand in-person interviewees did not differ significantly. Theevidence did not indicate that the mailed questionnaire respondentsanswered more carelessly or in a less coherent manner. The levelof evaluation was affected by the method, but the structureof the answers was not. The results imply that most estimatesof popular support for political leaders underestimate the levelof disapproval. 相似文献
