The central purposes of this study were to review the development and evolution of the Scientific Attitude Inventory (SAI) and then reevaluate the psychometric properties of the revised form of the SAI, the Scientific Attitude Inventory II (SAI‐II). The SAI‐II was administered to a convenience sample of 543 middle and high school students from five teachers in four schools in four school districts in San Antonio, Texas, at the beginning of the 2004–2005 school year. Confirmatory factor analysis on the full data set failed to support the existence of a 12‐factor structure (as proposed by the scale developers) or a one‐factor structure. The data were then randomly divided into exploratory [exploratory factor analysis (EFA)] validation and confirmatory [confirmatory factor analysis (CFA)] cross‐validation sets. Exploratory and confirmatory models yielded a three‐factor solution that did not fit the data well [χ² (321) = 646, p < .001; RMSEA = .061 (.90 CI = .054–.068); and CFI = .81]. The three factors were labeled “Science is About Understanding and Explaining” (13 items), “Science is Rigid” (6 items), and “I Want to Be a Scientist” (8 items). The α‐coefficients for these three factors ranged from 0.59 to 0.85. Whether these identified subscales are valid will require independent investigation. In this sample, and consistent with prior publications, the SAI‐II in its current form did not have satisfactory psychometric properties and cannot be recommended for further use. © 2008 Wiley Periodicals, Inc.

The new oracle: Self-help books in American culture     

Steven Starker 《Publishing Research Quarterly》1988,4(2):26-32

The self-help book in America appears to occupy a social niche roughly on a par with that of the legendary oracle at Delphi. Offering wisdom and enlightenment at discount prices, it speaks to a vast audience on a variety of topics, and provides specific directions for achieving love, health, wealth, peace of mind, and any number of practical skills. It is too prevalent and powerful a phenomenon to overlook, despite its belonging to “pop” culture. Inasmuch as self-help books are dispensing advice to millions on matters physical, psychological, and spiritual, they cannot responsibly be ignored by social scientists and health care practitioners. Questions regarding their relative merits and potential dangers deserve careful consideration. This article is an excerpt from chapter 1 ofOracle at the Supermarket, published by Transaction Publishers.  相似文献

PUBLIC OPINION AND THE TRANSFORMATION OF THE SOVIET UNION     

Dobson  Richard B.; Grant  Steven A. 《Int. Journal of Public Opinion Research》1992,4(4):302-320

This article examines the relationship between public opinionand the transformation of the Soviet Union. Results of an August1990 survey showed that the majority of adults supported democraticreform, but lacked confidence in the Soviet regime. Young andmiddle-aged people, urban residents, and those with higher educationtended to be more supportive of democratic reform and more alienatedfrom the regime. The nationalities differed widely in supportfor democratic reform and confidence in the regime. In the partlydemocratized political system, Boris Yeltsin acquired a broadfollowing by appealing to the electorate and advocating radicalchange. A February 1991 poll showed that his support was greatestamong Russians who backed the Russian parliament and stronglyendorsed democratic reform and private enterprise. With suchbacking, Yeltsin won the June 1991 Russian presidential electionand then mobilized popular opposition to the August coup attempt.The coup's failure dealt a fatal blow to Communist rule, Gorbachev'sleadership, and the Soviet Union itself.  相似文献   

Valuing the Arts: A Contingent Valuation Approach   总被引：5，自引：3，他引：2  

Eric Thompson  Mark Berger  Glenn Blomquist  Steven Allen 《Journal of Cultural Economics》2002,26(2):87-113

Government funding of the arts has received considerable attention in the United States in recent years. Efforts to cut funding to the National Endowment for the Arts and declining budgets for state arts agencies have raised questions about how much individuals value the arts. This paper applies the contingent valuation method to assess this value, using surveys of random households and of arts patrons. Our analysis estimated a mean willingness to pay (WTP) among all Kentucky households from $6 to$27, depending on the estimation technique used and on whether the scenario discussed is to increase arts performances by 25 per cent, or to avoid a 25per cent or 50 per cent decrease in the number of performances. Among arts patron households, the mean WTP ranges from $61 to $132.Consumer demand for arts performances in large part follows a predictable pattern. The likelihood of respondents agreeing to make the donation that is requested rises as the size of the donation decreases. The likelihood is higher to avoid a 50 per cent decline in performances than to avoid a 25 percent decline in performances. The mean WTP rises with income, and arts patron households have a much higher WTP than all households. WTP rises with on-site use factors such as frequency of attendance. The WTP also rises for arts patrons households with off-site use such as watching arts events on television or reading about the arts in newspapers and magazines.  相似文献
