Maintaining long-term participation in citizen science projects is challenging; thus, it is important for project developers to use effective techniques to motivate participants. One approach is to incorporate anthropomorphism (ascribing humanlike qualities to a non-human agent) when designing and deploying technology. In a quasi-experimental study...
Map graphics are often used for hazard risk communication, layered with numerical, verbal, and visual information to describe an uncertain threat. In the hurricane context, graphics are used to communicate the probability of different threats over a forecasting period. While hurricane graphics have been studied in the past, they have not been desig...
Fine particulate matter (PM 2.5 ) is a leading contributor to premature death, disease, and environmental degradation globally. Wildfire smoke is a primary source of air pollution in the United States. However,...
Accurate sub-city fine particulate matter (PM2.5) estimates could improve epidemiological and health-impact studies in cities with heterogeneous distributions of PM2.5, yet most cities globally lack the monitoring density necessary for sub-city-scale estimates. To estimate spatiotemporal variability in PM2.5, we use machine learning (Random Forests...
Atmospheric particulate matter smaller than 2.5 µm in diameter (PM2.5) has a negative impact on public health, the environment, and Earth's climate. Consequently, a need exists for accurate, distributed measurements of surface-level PM2.5 concentrations at a global scale. Existing PM2.5 measurement infrastructure provides broad PM2.5 sampling cover...
Atmospheric particulate matter smaller than 2.5 microns in diameter (PM2.5) impacts public health, the environment, and the climate. Consequently, a need exists for accurate, distributed measurements of surface-level PM2.5 concentrations at a global scale. Remote sensing observations of aerosol optical depth (AOD) have been used to estimate surface...
This theoretical paper proposes a framework for how citizen science can be adapted to organizational contexts. Using an “input, process, output” approach, this model proposes organizational factors (e.g., communication channels and styles, and organizational structure) that should be considered when choosing among citizen science approaches (e.g.,...
A pilot field campaign was conducted in the fall and winter of 2017 in northern Colorado to test the deployment of the Aerosol Mass and Optical Depth (AMOD) instrument as part of the Citizen-Enabled Aerosol Measurements for Satellites (CEAMS) network. Citizen scientists were recruited to set up the device to take filter and optical measurements of...
This study explored an underserved population, Native American youth, regarding health communication about sexually transmitted infections (STIs) and HIV/AIDS. Determining communication patterns of these youth, who markedly differ from the general population on access to health facilities and information, will inform public policy about lessening N...
The authors compared local TV news with national TV news in terms of cancer coverage using a nationally representative sample of local nightly TV and national network TV (i.e., ABC, CBS, NBC, and CNN) cancer news stories that aired during 2002 and 2003. Compared with national TV news, local TV cancer stories were (a) much shorter in length, (b) les...
This study investigated the effect of message attributes on responses to health messages. The authors examined 3 variables-responsibility attribution (individual vs. social), source (personal blog vs. online magazine), and illness (stigmatized vs. nonstigmatized)-for effects on young adults' health-related attitudes and behaviors. Responsibility at...
We are writing to urge AAAS to reconsider its policy against mandated labeling of so-called genetically modified (GM) foods ([ 1 ][1]). We do not, as a group, have any position on GM foods, for or against, but we are concerned that AAAS's position represents a poorly informed approach to
Adolescents’ wishful identification with televised scientist characters was examined as related to interactions among the following variables: gender of participant, gender of scientist character, program genre, and selected character attributes. Findings indicated some gender differences in adolescents’ wishful identification with scientist charac...
To determine whether differences in nutrition knowledge affected how women (a high-involvement group) interpreted intrinsic cues (ingredient list) and extrinsic cues ("all natural" label) on food labels.
A 2 (intrinsic cue) × 2 (extrinsic cue) × 2 (nutrition knowledge expert vs novice) within-subject factorial design was used. Participants were 106...
This content analysis examined portrayals of scientist characters in 14 television programs popular among or likely to have been viewed by middle school-age children. While male scientists significantly outnumbered and appeared in significantly more scenes than did female scientists, males and females were depicted similarly in reference to profess...
Media are popular sources of cancer information, yet little is known about how survivors are depicted.
This study analyzes coverage of cancer survivors in a nationally representative sample of newspapers and television newscasts. Stories were coded for cancer type, gender, age, survivorship length and status, treatment types, and spirituality, amon...
Prior research on knowledge gap effects, in health as well as in other domains, has focused largely on assessing individual-level differences in exposure to news based on self-report of media use. Inherent inferential limitations of this approach are addressed by testing the hypothesis that the relationship between education and cancer prevention k...
Using a nationally representative sample, this study examined the possible relationship between amount of alcohol and tobacco advertising and related news-editorial content. This study found less tobacco and alcohol advertising in newspapers than did previous research and no relationship between coverage and number of advertisements.

Early adolescence is a critical time for fostering girls' awareness and interest in science, engineering, and technology careers as they actively construct their identities. Possible selves theory describes the factors that influence adolescent girls as they create current and future identities. Research suggests that media models can influence vie...
A content analysis of cancer news coverage in a sample of local and national newspapers, television, and magazines was conducted for the years 2002 and 2003. Analyses compared proportions of mentions of cancer sites with proportional contribution to cancer incidence and mortality based on available epidemiological estimates. Analyses also examined...
The present study seeks to establish the extent to which media coverage acknowledges alcohol's contribution to violent crime as well as to motor vehicle injuries and other injury incidents.
The study content-analyzes a unique sample, closely approximating national representativeness, of local and national television news, local newspapers, and nati...
To characterise the relative amount and type of daily newspaper, local and national TV newscast, and national news magazine coverage of tobacco control issues in the United States in 2002 and 2003.
Content analysis of daily newspapers, news magazines, and TV newscasts.
Items about tobacco in daily newspapers, local and national TV newscasts, and th...
In this experiment, we examine effects of television dramas on support for controversial public policies (gay marriage and the death penalty) and explore mechanisms that may explain such effects. The dramas influenced support for death penalty but not gay marriage. As predicted, exposure to the relevant drama eliminated the relationship between pri...
This article presents 1 approach to constructing a valid national sample of local news outlets. Using designated market areas that represent the dominant geographic area of influence for television stations, researchers can create a nationally representative sample of local media, including television and newspaper outlets. A method for adapting th...
Unproven medical treatments are widely marketed, and are especially accessible via the Internet. Little is known about factors that may increase the persuasiveness of information used to promote such unproven treatments. This article examines the effect of scientese (use of scientific jargon) and attributed versus unattributed citations on message...
This study analyzes characters in four children's science education television programs. Results indicated that these programs presented some counter-stereotypical images of scientists and people interested in science. Males and females were equally likely to be scientists, and they were on screen for the same amount of time per episode. Also, stat...
A random phone survey of 300 small businesses in Colorado was conducted to help the Colorado Pollution Prevention Partnership develop a pollution-prevention campaign. Results showed respondents understood the concept of pollution prevention and were taking steps to reduce their pollution. Costs appeared to be the most serious barrier to pollution p...
This study analyzes the auditory, visual, and information‐presentation pace of children's science television programs. These half‐hour programs averaged more than 19 sound effects per minute, 14 visual changes (cuts, wipes, and fades/dissolves) per minute, and more than 27 topic shifts per program. These results indicate that the current crop of pr...
Several media effects perspectives suggest that televised images can influence children's perceptions of science and scientists. This study analysed images of science and scientists in four children's educational science programmes. The images of science as truth, as fun, and as a part of everyday life, as well as the image that science is for ever...

Mass media are important sources of science information for many adults. However, this study, which reports a content analysis of science stories in 100 US newspapers, found that while 70 newspapers carried science stories, the majority of these stories contained little scientific explanation. Ten percent or less of content was comprised of elucida...
Television teaches children gender-specific behaviors, attitudes, characteristics, and personality traits. Research indicates that by observing male and female characters on television, children learn to label certain characteristics and behaviors as masculine or feminine and to assign traditional sex-role stereotypes to careers. Content studies of...
Technical communication curricula vary because faculty use a variety of approaches to develop them. This essay suggests guidelines for curriculum and program development in technical communication based on a review of the relevant survey literature on the professional roles played by technical communicators, a review of academic literature on techn...
In an effort to examine the ways in which content and framing components of mediated risk messages influence individuals' cognitive and affective responses, this study asked university students to read and respond to two risk stories that varied along four dimensions: level of risk expressed, severity of health symptoms experienced as a result of t...
