Two experiments were conducted to explore the contributions of sexual and violent images contained in movie previews on viewers' anticipated perceptions and enjoyment of previewed films. In neither study were portrayals of sex or violence directly associated with greater anticipated enjoyment. However, both studies provided evidence that sexual and violent portrayals may indirectly enhance viewers' enjoyment via perceptions of heightened suspense (Study 1) or heightened humor (Study 2). These results are discussed in terms of viewers' responses to media images of sexuality and violence, and the importance of these portrayals in the marketing of motion pictures.  相似文献

ABSTRACT

Boundary walls are neglected but important parts of historic urban environments, and they are often prone to serious deterioration. Understanding moisture and salt dynamics within boundary walls can help infer the causes and dynamics of deterioration. This investigation investigates the patterns of moisture, salt, and deterioration on a 300 year old limestone boundary wall in Worcester College, Oxford. Multiple methods to assess moisture and salts within and across the wall (electrical resistivity tomography, handheld resistivity-based moisture meter, paper pulp poultices, scanning electron microscopy, inductively coupled plasma optical emission spectrometry, and ion chromatography of small scale sampling of deteriorated limestone) were used in conjunction with decay mapping of both sides of the wall. The salt weathering strongly correlates with severely weathered zones at the wall and salts, mainly sulfates, seem to be the main agent of decay processes. The combined results demonstrate that the environmental influences driving stone decay can differ on a very small scale even at a comparatively simple structure like a boundary wall, and that repairs can have adverse effects if the patterns of salt and moisture dynamics are not sufficiently known.  相似文献

ABSTRACT

The prospect of enhancing ourselves through the use of new biotechnologies is for the most part, hypothetical. Nevertheless, the question of whether we should undertake such enhancement is worthy of discussion as it may become possible in the future. In this article, we consider one form of argument that conservative opponents of biotechnological means of enhancement (bioconservatives) deploy in opposition to the use of enhancement technologies—the backfiring objection. This is the objection that the use of such technologies is liable to go wrong and lead to outcomes that are inferior to the outcomes intended. We will argue that the objection is not nearly as significant as bioconservatives suppose it to be. Bioconservatives sometimes supplement the backfiring objection by arguing that change will be irreversible, that the new (or the unconventional) is especially liable to backfire and that humans possess severe and permanent limitations which cannot be overcome. We consider these ways of supplementing the backfiring objection and argue that each of them, when properly understood, is of limited value to the bioconservative. We also consider how traditional approaches to moral education can be supplemented by bioenhancement.  相似文献

For the British teacher interested in children and books, the year's best buy has been a monthly review sheet produced by two Sheffield teachers; 60p for twelve issues, post paid, promptly delivered. CLE invited Jane Powell and Steve Bowles to describe their project; and we publish extracts to illustrate the practical nature of their reviews.  相似文献
