Abstract The Science Explorations program was developed by the Milwaukee Public Museum (MPM) out of a desire to use the unique resources of MPM to advance informal science education and to address a community need of local and national concern: improving science education and accessibility for underserved audiences. In 2002, with support from the National Science Foundation (NSF) and private donors, MPM launched this after‐school program for a target group of urban, mostly minority, middle school girls, a group at risk for underachievement in science and technology. The museum staff built a combined program with five middle schools and also sought to reach out to family members of the participating girls in order to increase support for the young women's science endeavors. A three‐year evaluation of the Science Explorations program demonstrated positive findings from primarily quantitative data. An aim of this article is to present findings from the qualitative data to shed light on the reasons this program met nearly all of its targets. Findings from case studies and qualitative interviews suggest that the museum staff's efforts to demystify science—a process that provided ongoing access to real scientific endeavors and invited personal contact with scientists—influenced the program's success. Findings also suggest that strong school liaisons may help increase family support for young women's scientific pursuits, which can in turn play a role in their success in this program. 相似文献

This study tested implications of new genetic discoveries for understanding the association between parental investment and children’s educational attainment. A novel design matched genetic data from 860 British mothers and their children with home-visit measures of parenting: the E-Risk Study. Three findings emerged. First, both mothers’ and children’s education-associated genetics, summarized in a genome-wide polygenic score, were associated with parenting—a gene–environment correlation. Second, accounting for genetic influences slightly reduced associations between parenting and children’s attainment—indicating some genetic confounding. Third, mothers’ genetics were associated with children’s attainment over and above children's own genetics, via cognitively stimulating parenting—an environmentally mediated effect. Findings imply that, when interpreting parents’ effects on children, environmentalists must consider genetic transmission, but geneticists must also consider environmental transmission. 相似文献

The scientific community of earthquake experts has long grappled with how to communicate earthquake probabilities successfully to non-scientific publics. Perhaps most central to their concern is the widely held belief that scientists can actually predict earthquakes when, in fact, they cannot. The potential consequences of this miscommunication problem were appallingly realized as a result of the 6 April 2009 earthquake in L’Aquila, Italy. Failed risk communication among scientists, a public official, and L’Aquila residents prior to the earthquake resulted in 309 deaths, 1500 injuries, and 65,000 people displaced from their homes, as well as the sentencing of six scientists and one public official to six years in prison for manslaughter. This paper examines how and why the L’Aquila Earthquake communication crisis ultimately redefined the international scientific earthquake community of practice and its discourse beyond that of community resilience to organizational learning and renewal. 相似文献

James C. McCroskey passed away on December 27, 2012. He contributed immensely to the study of human communication. He led the field in in-field publications and citations. Perhaps his most lasting contribution is naming and measuring communication constructs. James C. McCroskey contributed substantially to Communication Research Reports as a past editor, editorial board member, and contributing author. This essay is a personal and professional remembrance of James C. McCroskey. 相似文献

Recent communication research shows several paths to improving accuracy in deception detection. According to truth-default theory, one promising approach is diagnostic questioning. A sample of elite U.S. Customs agents participated in a deception detection task. Agents viewed senders who were interrogated with one of three different sets of questions that differed in diagnostic utility. The different questioning sets produced a 36-point swing in accuracy from 42% to 78% accuracy. These findings demonstrate that how someone is questioned can make a substantial difference in deception detection accuracy and that improved accuracy is possible with diagnostic questioning. 相似文献

This study presents the IDEA (internalization, distribution, explanation, action) model as an easy-to-use and situationally generalizable framework for quickly developing effective messages instructing people on how to protect themselves before and during high-risk events, crises, disasters, and other emergencies. The model consists of four elements: helping message recipients internalize the potential impact of the risk or crisis event, identifying appropriate channels and strategies for distributing the risk or crisis event messages, offering a brief and intelligible explanation of the nature of the risk or crisis, and providing specific self-protective action steps for people to take. The model may be used to design messages in any risk, crisis, or emergency context. Through a posttest-only quasi-experimental cross-sectional research experiment, this study measured the perceived message effectiveness, cognitive understanding, and behavioral intentions of those viewing a television news story about a crisis situation employing the IDEA model compared to those viewing a similar story replicating typical crisis event news stories delivered to general publics. This comparative examination revealed that the message designed according to the IDEA model was significantly more effective than the status quo message and resulted in greater behavioral intentions to engage in appropriate self-protective actions in the event of an acute risk or crisis situation. Strategies for implementing the model are also provided. 相似文献
