This agenda-setting study explores ways that individuals processinformation issues by examining two potential public agendasources: the news media and the president of the USA. The researchersused a two-site study to examine the magnitude of influencefrom media exposure and perceived credibility of source. Itwas found that the higher the level of exposure to media anda presidential state-of-the-union message, the more likely thatissues were considered important. However, when both were examinedsimultaneously, media exposure was the more powerful predictor.Source credibility, both of the media and the president, wasalso found to influence how people perceived the importanceof issues.  相似文献

Forecast errors in preelectoral polls are common. Since theNicaraguan Election in 1990, a common assumption is that wheredemocratic practices are not equal to those of the developedcountries (authoritarian, in transition, etc.), the errors inpredicting electoral outcomes with the help of pre-electoralpolls result mostly from contextual effects related to the authoritariannature of the political systems. Forecast errors in developeddemocracies have been explained by flaws in sampling (GreatBritain), last minute changes in preferences (Spain, UnitedStates, and France) and a social desirability bias in the UnitedStates. The intention of this paper is to show that in Mexicoboth the accuracy and the sources of error in predicting electoralresults are very similar to those confronted by pollsters elsewhere:mostly sampling and allocation of nonrespondents and those whoare undecided. An extensive data set of pre-electoral pollsconducted in Mexico shows an average error in the order of 3–5percentage points. Some of this error could be related to sociallydesirable answers derived from contextual effects, but thiseffect is small and must not be generalized.  相似文献

Abstract

In preparation for a major exhibition at the National Gallery of Scotland in 2005, a thorough technical examination of VISION OF THE SERMON by Paul Gauguin was undertaken for the first time since the painting's acquisition in 1925. An inter-disciplinary approach to the research was adopted in an attempt to assess how innovative were the materials and techniques employed by Gauguin in this iconic work. The importance of the unique customs and religious piety of Brittany in 1888 to the iconography of Vision is discussed, as well as the various ways in which the original appearance of the painting has altered over time. Changes have occurred through both the natural ageing of materials and as a result of human intervention, particularly an aqueous lining and reframing. Analysis suggests that the paint medium consists of several different drying oils, confounding years of speculation that it may contain wax. The discovery that the original surface coating contains beeswax and tallow has grave implications for the feasibility of future conservation treatments. Following Gauguin's accusation of plagiarism by Emile Bernard, a tentative comparison is made between Vision and the latter's Breton Women in the Meadow. This reveals that while compositional similarities exist, Vision is far more complex, both in conception and execution.  相似文献
