    Author Institution: School of Natural Resources and College of Education, The Ohio State UniversityThe Ohio Sea Grant Education Program conducted a baseline study of ocean and Great Lakes awareness among Ohio's fifth and ninth grade students in 1979, and repeated it with some curriculum-specific additions as a longitudinal study in 1983. This report of the 1983 data indicates that over the 4-year period the ninth graders, cohort of the 1979 fifth graders, increased over 10% in ocean and Great Lakes knowledge scores. However, information considered critical to responsible decision-making is still lacking. Attitudes toward Lake Erie and the oceans, while remaining slightly positive for the group, did not change commensurate with knowledge. A new set of test items dealing specifically with information from Ohio Sea Grant curriculum materials was added to the survey in 1983 to provide a new baseline for future testing. The main self-reported source of student information about these topics changed over the period, so that in 1983 students in both grades were relying more on the classroom than on media sources for aquatic information. The survey will be repeated at regular intervals, continuing a longitudinal study unique to marine and aquatic education in North America

    Ohio Students' Knowledge and Attitudes about the Oceans and Great Lakes

    Author Institution: School of Natural Resources, The Ohio State University ; Science and Mathematics Education, The Ohio State UniversityA program to develop instructional materials for implementing marine and aquatic education in Ohio middle schools was begun by Ohio Sea Grant in 1977. This was followed 3 years later by a grant to disseminate the materials to schools in Ohio. To determine the effectiveness of the dissemination process a baseline study was conducted in the autumn of 1980. The survey obtained information on attitudes and knowledge of the Great Lakes and oceans from fifth and ninth grade students in randomly selected schools within 3 arbitrarily determined zones: the lake region, the central region and the Ohio River region. In addition, students responded to items to determine their perceptions of the sources of their knowledge

    Microbial fuel cell technology for measurement of microbial respiration of lactate as an example of bioremediation amendment

    Microbial fuel cell (MFC) based sensing was explored to provide for the development of an insitu bioremediation monitoring approach for substrate concentrations and microbial respiration rates. MFC systems were examined in column systems where Shewanella oneidensis MR1 used an external electron acceptor (an electrode) to metabolize lactate (a bioremediation additive) to acetate. Column systems were operated with varying influent lactate concentrations (0-41mM) and monitored for current generation (0.01-0.39mA). Biological current generation paralleled bulk phase lactate concentration both in the influent and in the bulk phase at the anode; current values were correlated to lactate concentration at the anode (R 2=0.9), The electrical signal provided real-time information for electron donor availability and biological activity. These results have practical implications for efficient and inexpensive real-time monitoring of insitu bioremediation processes where information on substrate concentrations is often difficult to obtain and where information on the rate and nature of metabolic processes is neede

    Utilizing Expert Knowledge in Estimating Future STS Costs

    Get PDF
    A method of estimating the costs of future space transportation systems (STSs) involves classical activity-based cost (ABC) modeling combined with systematic utilization of the knowledge and opinions of experts to extend the process-flow knowledge of existing systems to systems that involve new materials and/or new architectures. The expert knowledge is particularly helpful in filling gaps that arise in computational models of processes because of inconsistencies in historical cost data. Heretofore, the costs of planned STSs have been estimated following a "top-down" approach that tends to force the architectures of new systems to incorporate process flows like those of the space shuttles. In this ABC-based method, one makes assumptions about the processes, but otherwise follows a "bottoms up" approach that does not force the new system architecture to incorporate a space-shuttle-like process flow. Prototype software has been developed to implement this method. Through further development of software, it should be possible to extend the method beyond the space program to almost any setting in which there is a need to estimate the costs of a new system and to extend the applicable knowledge base in order to make the estimate

    The Policy of Enforcement: Red Light Cameras and Racial Profiling

    The article of record as published may be located at http://dx.doi.org/10.1177/1098611115586174We explore the question of whether some of the often conflicting evidence of racial profiling can be cleared up using red light camera observations to measure racial disparities in traffic violations. Using data from cameras at intersections matched to census data, we find that although citations from the red light cameras are issued to a disproportionate number of minorities based on the racial composition of the surrounding location, the racial composition of the violator is consistent with the racial composition of the block group in which they reside. Our study indicates that red light cameras may have a present and future role in assisting public policy makers on issues of racial profiling thresholds

    Exploring Source Credibility when Communicating about Agricultural Science on Twitter

    Get PDF
    Universities must strategically communicate agricultural science to effectively reach millennials skeptical of agricultural innovations and constantly assessing the credibility of online information. Universities are trusted information sources and must maintain credibility on social media platforms such as Twitter, used by millennials to receive and share information. Source credibility seeks to understand message source and recipient characteristics that influence recipients’ perceptions of a source’s expertise and trustworthiness. The purpose of this study was to explore differences in engagement when specific factors affecting source credibility were emphasized when communicating with millennials about agricultural science on Twitter. The purpose was accomplished by describing the level of engagement and the differences in engagement observed between perceived gender, race, and age of university scientists. Over seven months, researchers wrote press releases about published journal articles authored by two or more diverse, university-affiliated scientists. They published multiple tweets about each release, with the only difference being the scientists’ headshots. Scientists were categorized as perceived male versus female, White versus Non-White, and older versus younger. Descriptive analysis of engagement metrics from 32 tweets found those with females performed better than those with males. Non-White scientist tweets performed better with the exception of engagement rate. Tweets featuring younger scientists received more engagement than older. The exploratory results implied tweets featuring young, Non-White females may elicit higher engagement. Future studies should examine if engagement metrics are correlated with source credibility dimensions. Strategically featuring diverse scientists in research communication may be utilized to build engagement in universities’ social media
