Using the contemporary debate in the United States over embryonic stem cell research as a test case, we outline a theoretical framework that points to the central impact of value predispositions, schema, political knowledge, and forms of mass media use in shaping public perceptions of science. In the process, by proposing an alternative approach to the dominant science literacy model, we address the existing divide between survey-based and ethnographic studies. Analyzing nationally representative survey data collected in the US in the fall of 2003, our findings suggest that value predispositions related to Christian conservatism and social ideology, along with schema related to abortion and reservations about science, serve as primary influences on citizen evaluations of embryonic stem cell research and therapeutic cloning, while our measure of issue-specific political knowledge had no statistically significant impact. In addition, after all controls, attention to newspaper coverage along with various forms of genre-specific entertainment television use have unique influences on citizen evaluations, suggesting that the mass media provide an important part of the social context by which citizens judge controversial science. Other survey results since our data collection in 2003 lend support to our findings. Religious and ideological values appear to filter the influence of information disseminated by scientific institutions. We conclude by discussing future research that connects findings from ethnographic studies with surveybased approaches.

What role do objective weather conditions play in coastal residents' perceptions of local climate shifts and how do these perceptions affect attitudes toward climate change? While scholars have increasingly investigated the role of weather and climate conditions on climate-related attitudes and behaviors, they typically assume that residents accurately perceive shifts in local climate patterns. We directly test this assumption using the largest and most comprehensive survey of Gulf Coast residents conducted to date supplemented with monthly temperature data from the U.S. Historical Climatology Network and extreme weather events data from National Climatic Data Center. We find objective conditions have limited explanatory power in determining perceptions of local climate patterns. Only the 15- and 19-year hurricane trends and decadal summer temperature trend have some effects on perceptions of these weather conditions, while the decadal trend of total number of extreme weather events and 15- and 19-year winter temperature trends are correlated with belief in climate change. Partisan affiliation, in contrast, plays a powerful role affecting individual perceptions of changing patterns of air temperatures, flooding, droughts, and hurricanes, as well as belief in the existence of climate change and concern for future consequences. At least when it comes to changing local conditions, "seeing is not believing." Political orientations rather than local conditions drive perceptions of local weather conditions and these perceptions-rather than objectively measured weather conditions-influence climate-related attitudes.

This article considers the process by which local economic news coverage influences individual evaluations of the economy. We improve on prior research by capturing a wider range of news sources (including national network news, national newspapers, local television news, and local newspapers) and connecting the effects of this coverage on individual level attitudes. We find that current personal financial evaluations, personal financial expectations, and short-term (12-month) expectations for the U.S. economy are related to national network coverage. Local television coverage of the economy is related to personal financial evaluations but not short-term economic expectations and local print news is important in structuring expectations of future business conditions. Overall, the findings illustrate important differences in economic coverage across media outlets and the effects of these differences on economic expectations. Exposure to different sources of economic information have significantly different effects on economic perceptions-suggesting a more complicated and nuanced role for the news media in shaping economic perceptions than indicated by previous research.

In the following analysis, we investigate two important questions: (1) how closely does media coverage of the economy reflect real changes in eco nomic conditions? and (2) to what extent does economic coverage of the economy exert an independent effect on economic evaluations? We then use this information to explore Republican claims that media coverage of the economy hurt the Bush reelection campaign. Consistent with previous research, we find that, overall, the media tend to follow negative economic conditions more closely than positive economic conditions. In addition, news coverage appears to be strongly related to aggregate public evaluations of the economy, even after controlling for real economic conditions. Final ly, we also find that news coverage of the economy was significantly differ ent during 1982, 1991, and 1992 than during other years under study. During these years, coverage of the economy was more negative than would have been expected on the basis of economic conditions alone. The implications of these findings, particularly with respect to Republican claims of media bias, are explored.

Over the past several decades, the economic damage from flooding in the coastal areas has greatly increased due to rapid coastal development coupled with possible climate change impacts. One effective way to mitigate excessive economic losses from flooding is to purchase flood insurance. Only a minority of coastal residents however have taken this preventive measure. Using original survey data for all coastal counties of the United States Gulf Coast merged with contextual data, this study examines the effects of external influences and perceptions of flood-related risks on individuals' voluntary behaviors to purchase flood insurance. It is found that the estimated flood hazard conveyed through the U.S. Federal Emergency Management Agency's (FEMA's) flood maps, the intensities and consequences of past storms and flooding events, and perceived flood-related risks significantly affect individual's voluntary purchase of flood insurance. This behavior is also influenced by home ownership, trust in local government, education, and income. These findings have several important policy implications. First, FEMA's flood maps have been effective in conveying local flood risks to coastal residents, and correspondingly influencing their decisions to voluntarily seek flood insurance in the U.S. Gulf Coast. Flood maps therefore should be updated frequently to reflect timely and accurate information about flood hazards. Second, policy makers should design strategies to increase homeowners' trust in the local government, to better communicate flood risks with residents, to address the affordability issue for the low-income, and better inform less educated homeowners through various educational programs. Future studies should examine the voluntary flood insurance behavior across countries that are vulnerable to flooding.
