Teachers' Perspectives on Online Virtual Labs vs. Hands-On Labs in High School Science

NASA Astrophysics Data System (ADS)

Bohr, Teresa M.

This study of online science teachers' opinions addressed the use of virtual labs in online courses. A growing number of schools use virtual labs that must meet mandated laboratory standards to ensure they provide learning experiences comparable to hands-on labs, which are an integral part of science curricula. The purpose of this qualitative case study was to examine teachers' perceptions of the quality and effectiveness of high school virtual labs. The theoretical foundation was constructivism, as labs provide student-centered activities for problem solving, inquiry, and exploration of phenomena. The research questions focused on experienced teachers' perceptions of the quality of virtual vs. hands-on labs. Data were collected through survey questions derived from the lab objectives of The Next Generation Science Standards . Eighteen teachers rated the degree of importance of each objective and also rated how they felt virtual labs met these objectives; these ratings were reported using descriptive statistics. Responses to open-ended questions were few and served to illustrate the numerical results. Many teachers stated that virtual labs are valuable supplements but could not completely replace hands-on experiences. Studies on the quality and effectiveness of high school virtual labs are limited despite widespread use. Comprehensive studies will ensure that online students have equal access to quality labs. School districts need to define lab requirements, and colleges need to specify the lab experience they require. This study has potential to inspire positive social change by assisting science educators, including those in the local school district, in evaluating and selecting courseware designed to promote higher order thinking skills, real-world problem solving, and development of strong inquiry skills, thereby improving science instruction for all high school students.

The Impact of Teacher Quality Grants on Long-Term Professional Development of Physical Science Teachers

NASA Astrophysics Data System (ADS)

Urquhart, Mary L.; Bober, Kendra M.

2006-02-01

The Texas Higher Education Coordinating Board Teacher Quality Grants, supported through No Child Left Behind, are intended to ensure that secondary teachers of specific subjects are "highly qualified". Now in their third year, these grants have done much to shape long-term professional development for teachers in the physical sciences at the University of Texas at Dallas (UTD). The grants have also created a suite of challenges and benefits for the UTD Science Education M.A.T. program. Teacher Quality Grants are based on the No Child Left Behind framework that requires teachers to be "highly qualified" as defined by the state. Recruitment is required to be targeted at teachers who are uncertified or teach one or more classes out of their content area and who work in high needs local school districts. Many of the students brought into our program through these grants have incoming content knowledge in physics similar to that typical of undergraduate non-majors, and a large percentage are uncomfortable with basic mathematics as well. How and what we teach has been dramatically impacted by the Teacher Quality Grants, as have our assessments and evaluations. An ongoing challenge has been to implement a Physics Education Research (PER)-based course design while meeting the specific requirements of the Teacher Quality Grant program. The Teacher Quality Grants have also provided a great deal of opportunity to new and existing teachers in our program. A barrier to our teachers, rising tuition costs, has been removed and as a result a mandate has become a doorway of opportunity for physical science teachers.

Teacher Research Programs: An Effective Form of Professional Development to Increase Student Achievement and Benefit the Economy

NASA Astrophysics Data System (ADS)

Dubner, J.

2008-12-01

U.S. high school students perform markedly less well in science, technology, engineering and math (STEM) than students in other economically advanced countries. This low level of STEM performance endangers our democracy and economy. The President's Council of Advisors in Science and Technology's 2004 report attributed the shortfall of students attracted to the sciences is a result of the dearth of teachers sufficiently conversant with science and scientists to enable them to communicate to their students the excitement of scientific exploration and discovery, and the opportunities science provides for highly rewarding and remunerative careers. Nonetheless, the United States has made little progress in correcting these deficiencies. Studies have shown that high-quality teaching matters more to student achievement than anything else schools do. This belief is buttressed by evidence from Columbia University's Summer Research Program for Science Teachers (SRP) that highly motivated, in-service science teachers require professional development to enable them and their students to perform up to their potential. Columbia's Summer Research Program is based on the premise that to teach science effectively requires experience in using the tools of contemporary science to answer unsolved questions. From its inception, SRP's goal has been to enhance interest and improve performance in science of students. It seeks to achieve this goal by increasing the professional competence of teachers. The reports of Elmore, Sanders and Rivers, and our own studies, show that professional development is a "key lever for improving student outcomes." While most middle and high school science teachers have taken college science courses that include cookbook laboratory exercises, the vast majority of them have never attempted to answer an unsolved question. Just as student learning depends on the expertise of teachers, the expertise of teachers depends on the quality of their professional development. Columbia University's teacher research program is a very effective form of professional development for pre- college science teachers and has a direct correlation to increased student motivation and achievement in science. The Program is premised on the beliefs that hands-on experience in the practice of science improves the quality and authenticity of science teaching, and that improved science teaching is correlated with increased student interest and achievement in science. The author will present the methodology of the program's evaluation citing statistically significant findings. The author will also show the economic benefits of teacher participation in a well-designed research program.

Marlina, L.; Liliasari; Tjasyono, B.; Hendayana, S.

2017-02-01

The teacher is one important factor in the provision of education in schools. Therefore, improving the quality of education means we need to enhance the quality and the professionalism of teachers. We offer a solution through education and training of junior high school science teachers in developing the instructional design of Earth and Space Sciences (IPBA). IPBA is part of the science subjects which is given to students from elementary school to college. This research is a preliminary study of junior high school science teacher professionalism in creating instructional design IPBA. Mixed method design is used to design the research. Preliminary studies conducted on junior high school science teacher in one MGMPs in South Sumatera, and the respondent are 18 teachers from 13 schools. The educational background of science teachers who teach IPBA not only from physical education but also biology and agriculture. The result of preliminary study showed that the ratio of teachers who teach IPBA are 56% from physic education, 39% from biology, and 5% from agriculture. The subjects of IPBA that considered difficult by teachers are the distribution of sun, moon, and satellite motion; specific processes in lithosphere and atmosphere; and the correlation between lithosphere and atmosphere with the environment. The teachers also face difficulty in preparing media, choosing the right methods in teaching IPBA.

An exploration of elementary science teachers' expertise, creativity skills, and motivation in relation to the use of an innovation and the delivery of high-quality science instruction

NASA Astrophysics Data System (ADS)

Falkenberg, Karen L.

This two-year study sought to uncover characteristic differences among a purposive sample of 23 elementary teachers who were using an elementary science innovation with various levels of proficiency. Two theoretical frameworks supported the development of the research, the Concerns Based Adoption Model Level of Use (LoU) (Hord, Rutherford, Huling-Austin & Hall, 1987) and Amabile's (1996) Componential Model of Creativity. Both qualitative and quantitative methodologies were employed to gather data on participants' science content knowledge, pedagogical skill, creativity relevant process skills, motivation orientation, self-efficacy, outcome expectancy and workplace environment. Results dispute the common conception among educators that "mechanical use" teachers do not provide high quality lessons. A new method for categorizing teachers' proficiency with an innovation is suggested by this study that incorporates both qualitative data from the LoU interview and classroom observation. Additionally, results show that the quality of the observed science lessons was associated with a teacher's creativity. The data suggest that a teacher's creativity relevant process skills and expertise are indicators of lesson quality. There were important differences among teachers' conceptions of creativity, how they involved students in the reported lessons and in the type of adaptations they made to the innovation. The more creative teachers tended to provide lessons that were more complex, of longer duration, had ties to student home life, and used multiple resources. Following an analysis of these results is a set of suggested professional development strategies and workplace changes to support less proficient teachers in their ability to provide higher quality elementary science lessons.

An analysis of high-performing science students' preparation for collegiate science courses

NASA Astrophysics Data System (ADS)

Walter, Karen

This mixed-method study surveyed first year high-performing science students who participated in high-level courses such as International Baccalaureate (IB), Advanced Placement (AP), and honors science courses in high school to determine their perception of preparation for academic success at the collegiate level. The study used 52 students from an honors college campus and surveyed the students and their professors. The students reported that they felt better prepared for academic success at the collegiate level by taking these courses in high school (p<.001). There was a significant negative correlation between perception of preparation and student GPA with honors science courses (n=55 and Pearson's r=-0.336), while AP courses (n=47 and Pearson's r=0.0016) and IB courses (n=17 and Pearson's r=-0.2716) demonstrated no correlation between perception of preparation and GPA. Students reported various themes that helped or hindered their perception of academic success once at the collegiate level. Those themes that reportedly helped students were preparedness, different types of learning, and teacher qualities. Students reported in a post-hoc experience that more lab time, rigorous coursework, better teachers, and better study techniques helped prepare them for academic success at the collegiate level. Students further reported on qualities of teachers and teaching that helped foster their academic abilities at the collegiate level, including teacher knowledge, caring, teaching style, and expectations. Some reasons for taking high-level science courses in high school include boosting GPA, college credit, challenge, and getting into better colleges.

Examining Science Teachers' Argumentation in a Teacher Workshop on Earthquake Engineering

NASA Astrophysics Data System (ADS)

Cavlazoglu, Baki; Stuessy, Carol

2018-02-01

The purpose of this study was to examine changes in the quality of science teachers' argumentation as a result of their engagement in a teacher workshop on earthquake engineering emphasizing distributed learning approaches, which included concept mapping, collaborative game playing, and group lesson planning. The participants were ten high school science teachers from US high schools who elected to attend the workshop. To begin and end the teacher workshop, teachers in small groups engaged in concept mapping exercises with other teachers. Researchers audio-recorded individual teachers' argumentative statements about the inclusion of earthquake engineering concepts in their concept maps, which were then analyzed to reveal the quality of teachers' argumentation. Toulmin's argumentation model formed the framework for designing a classification schema to analyze the quality of participants' argumentative statements. While the analysis of differences in pre- and post-workshop concept mapping exercises revealed that the number of argumentative statements did not change significantly, the quality of participants' argumentation did increase significantly. As these differences occurred concurrently with distributed learning approaches used throughout the workshop, these results provide evidence to support distributed learning approaches in professional development workshop activities to increase the quality of science teachers' argumentation. Additionally, these results support the use of concept mapping as a cognitive scaffold to organize participants' knowledge, facilitate the presentation of argumentation, and as a research tool for providing evidence of teachers' argumentation skills.

Failures surrounding pharmaceutical quality, particularly with respect to product manufacturing issues and facility remediation, account for the majority of drug shortages and product recalls in the United States. Major scientific advancements pressure established regulatory paradigms, especially in the areas of biosimilars, precision medicine, combination products, emerging manufacturing technologies, and the use of real-world data. Pharmaceutical manufacturing is increasingly globalized, prompting the need for more efficient surveillance systems for monitoring product quality. Furthermore, increasing scrutiny and accelerated approval pathways provide a driving force to be even more efficient with limited regulatory resources. To address these regulatory challenges, the Office of Pharmaceutical Quality (OPQ) in the Center for Drug Evaluation and Research (CDER) at the U.S. Food and Drug Administration (FDA) harbors a rigorous science and research program in core areas that support drug quality review, inspection, surveillance, standards, and policy development. Science and research is the foundation of risk-based quality assessment of new drugs, generic drugs, over-the-counter drugs, and biotechnology products including biosimilars. This is an overview of the science and research activities in OPQ that support the mission of ensuring that safe, effective, and high-quality drugs are available to the American public.

A New Era of Science Education: Science Teachers' Perceptions and Classroom Practices of Science, Technology, Engineering, and Mathematics (STEM) Integration

NASA Astrophysics Data System (ADS)

Wang, Hui-Hui

Quality STEM education is the key in helping the United States maintain its lead in global competitiveness and in preparing for new economic and security challenges in the future. Policymakers and professional societies emphasize STEM education by legislating the addition of engineering standards to the existing science standards. On the other hand, the nature of the work of most STEM professionals requires people to actively apply STEM knowledge to make critical decisions. Therefore, using an integrated approach to teaching STEM in K-12 is expected. However, science teachers encounter numerous difficulties in adapting the new STEM integration reforms into their classrooms because of a lack of knowledge and experience. Therefore, high quality STEM integration professional development programs are an urgent necessity. In order to provide these high quality programs, it is important to understand teachers' perceptions and classroom practices regarding STEM integration. A multiple-case study was conducted with five secondary school science teachers in order to gain a better understanding of teachers' perceptions and classroom practices in using STEM integration. This study addresses the following research questions: 1) What are secondary school science teachers' practices of STEM integration? 2) What are secondary science teachers' overall perceptions of STEM integration? and 3) What is the connection between secondary science teachers' perceptions and understanding of STEM integration with their classroom practices? This research aims to explore teachers' perceptions and classroom practices in order to set up the baseline for STEM integration and also to determine STEM integration professional development best practices in science education. Findings from the study provide critical data for making informed decision about the direction for STEM integration in science education in K-12.

Facial appearance affects science communication.

PubMed

Gheorghiu, Ana I; Callan, Mitchell J; Skylark, William J

2017-06-06

First impressions based on facial appearance predict many important social outcomes. We investigated whether such impressions also influence the communication of scientific findings to lay audiences, a process that shapes public beliefs, opinion, and policy. First, we investigated the traits that engender interest in a scientist's work, and those that create the impression of a "good scientist" who does high-quality research. Apparent competence and morality were positively related to both interest and quality judgments, whereas attractiveness boosted interest but decreased perceived quality. Next, we had members of the public choose real science news stories to read or watch and found that people were more likely to choose items that were paired with "interesting-looking" scientists, especially when selecting video-based communications. Finally, we had people read real science news items and found that the research was judged to be of higher quality when paired with researchers who look like "good scientists." Our findings offer insights into the social psychology of science, and indicate a source of bias in the dissemination of scientific findings to broader society.

Scientists' and science writers' experiences reporting genetic discoveries: toward an ethic of trust in science journalism.

Geller, Gail; Bernhardt, Barbara A; Gardner, Mary; Rodgers, Joann; Holtzman, Neil A

2005-03-01

To describe the relationship between scientists and science writers and their experiences with media reporting of genetic discoveries. This study included individual interviews with 15 scientists who specialize in genetics and 22 science writers who have covered their stories and a qualitative analysis of the data. Scientists and science writers place an equally high priority on accuracy of media reports. They agree on what makes genetics stories newsworthy and the particular challenges in reporting genetic discoveries (i.e., poor public understanding of genetics, the association of genetics with eugenics, and the lack of immediately apparent applications of genetic discoveries to human health). The relationship between scientists and bona fide science writers is largely positive. Scientists tend to trust, respect, and be receptive to science writers. Both scientists and science writers acknowledge that trust is an essential component of a good interview. Science writers report a fair degree of autonomy with respect to the relationship they have with their editors. To the degree that trust facilitates the access that science writers have to scientists, as well as higher quality interviews between scientists and science writers, trust might also contribute to higher quality media reporting. Therefore, scientists and science writers have an ethical obligation to foster trusting relationships with each other. Future research should systematically explore ways to cultivate such relationships and assess their impact on the quality of science journalism.

Quality Assessment of Collection 6 MODIS Atmospheric Science Products

NASA Astrophysics Data System (ADS)

Manoharan, V. S.; Ridgway, B.; Platnick, S. E.; Devadiga, S.; Mauoka, E.

2015-12-01

Since the launch of the NASA Terra and Aqua satellites in December 1999 and May 2002, respectively, atmosphere and land data acquired by the MODIS (Moderate Resolution Imaging Spectroradiometer) sensor on-board these satellites have been reprocessed five times at the MODAPS (MODIS Adaptive Processing System) located at NASA GSFC. The global land and atmosphere products use science algorithms developed by the NASA MODIS science team investigators. MODAPS completed Collection 6 reprocessing of MODIS Atmosphere science data products in April 2015 and is currently generating the Collection 6 products using the latest version of the science algorithms. This reprocessing has generated one of the longest time series of consistent data records for understanding cloud, aerosol, and other constituents in the earth's atmosphere. It is important to carefully evaluate and assess the quality of this data and remove any artifacts to maintain a useful climate data record. Quality Assessment (QA) is an integral part of the processing chain at MODAPS. This presentation will describe the QA approaches and tools adopted by the MODIS Land/Atmosphere Operational Product Evaluation (LDOPE) team to assess the quality of MODIS operational Atmospheric products produced at MODAPS. Some of the tools include global high resolution images, time series analysis and statistical QA metrics. The new high resolution global browse images with pan and zoom have provided the ability to perform QA of products in real time through synoptic QA on the web. This global browse generation has been useful in identifying production error, data loss, and data quality issues from calibration error, geolocation error and algorithm performance. A time series analysis for various science datasets in the Level-3 monthly product was recently developed for assessing any long term drifts in the data arising from instrument errors or other artifacts. This presentation will describe and discuss some test cases from the recently processed C6 products. We will also describe the various tools and approaches developed to verify and assess the algorithm changes implemented by the science team to address known issues in the products and improve the quality of the products.

Best Practices: How to Evaluate Psychological Science for Use by Organizations.

PubMed

Fiske, Susan T; Borgida, Eugene

2011-01-01

We discuss how organizations can evaluate psychological science for its potential usefulness to their own purposes. Common sense is often the default but inadequate alternative, and bench-marking supplies only collective hunches instead of validated principles. External validity is an empirical process of identifying moderator variables, not a simple yes-no judgment about whether lab results replicate in the field. Hence, convincing criteria must specify what constitutes high-quality empirical evidence for organizational use. First, we illustrate some theories and science that have potential use. Then we describe generally accepted criteria for scientific quality and consensus, starting with peer review for quality, and scientific agreement in forms ranging from surveys of experts to meta-analyses to National Research Council consensus reports. Linkages of basic science to organizations entail communicating expert scientific consensus, motivating managerial interest, and translating broad principles to specific contexts. We close with parting advice to both sides of the researcher-practitioner divide.

Replicability and other features of a high-quality science: Toward a balanced and empirical approach.

PubMed

Finkel, Eli J; Eastwick, Paul W; Reis, Harry T

2017-08-01

Finkel, Eastwick, and Reis (2015; FER2015) argued that psychological science is better served by responding to apprehensions about replicability rates with contextualized solutions than with one-size-fits-all solutions. Here, we extend FER2015's analysis to suggest that much of the discussion of best research practices since 2011 has focused on a single feature of high-quality science-replicability-with insufficient sensitivity to the implications of recommended practices for other features, like discovery, internal validity, external validity, construct validity, consequentiality, and cumulativeness. Thus, although recommendations for bolstering replicability have been innovative, compelling, and abundant, it is difficult to evaluate their impact on our science as a whole, especially because many research practices that are beneficial for some features of scientific quality are harmful for others. For example, FER2015 argued that bigger samples are generally better, but also noted that very large samples ("those larger than required for effect sizes to stabilize"; p. 291) could have the downside of commandeering resources that would have been better invested in other studies. In their critique of FER2015, LeBel, Campbell, and Loving (2016) concluded, based on simulated data, that ever-larger samples are better for the efficiency of scientific discovery (i.e., that there are no tradeoffs). As demonstrated here, however, this conclusion holds only when the replicator's resources are considered in isolation. If we widen the assumptions to include the original researcher's resources as well, which is necessary if the goal is to consider resource investment for the field as a whole, the conclusion changes radically-and strongly supports a tradeoff-based analysis. In general, as psychologists seek to strengthen our science, we must complement our much-needed work on increasing replicability with careful attention to the other features of a high-quality science.

Socioscientific Argumentation: The effects of content knowledge and morality

NASA Astrophysics Data System (ADS)

Sadler, Troy D.; Donnelly, Lisa A.

2006-10-01

Broad support exists within the science education community for the incorporation of socioscientific issues (SSI) and argumentation in the science curriculum. This study investigates how content knowledge and morality contribute to the quality of SSI argumentation among high school students. We employed a mixed-methods approach: 56 participants completed tests of content knowledge and moral reasoning as well as interviews, related to SSI topics, which were scored based on a rubric for argumentation quality. Multiple regression analyses revealed no statistically significant relationships among content knowledge, moral reasoning, and argumentation quality. Qualitative analyses of the interview transcripts supported the quantitative results in that participants very infrequently revealed patterns of content knowledge application. However, most of the participants did perceive the SSI as moral problems. We propose a “Threshold Model of Knowledge Transfer” to account for the relationship between content knowledge and argumentation quality. Implications for science education are discussed.

College student perceptions of science teachers and the effect on science teaching as a career path

NASA Astrophysics Data System (ADS)

Cost, Michael George

2000-10-01

Past research documented that student perceptions of scientists constituted a stereotypical image that had a negative effect on the students' attitudes towards science and resulted in low numbers of students studying to become scientists and engineers in college. The present study paralleled the research on student perceptions of scientists to investigate to what extent student perceptions of science teachers affect their willingness to consider science teaching as a career. This was accomplished by surveying 91 college students and 25 science teachers at the beginning, middle, and end of the collegiate career path of becoming a science teacher. Each survey contained quantitative data utilizing seven-point semantic differential scales and written open response questions. In-depth interviews with two members of each level were conducted to supplement the survey data. The study found that college students begin college with a positive perception of teaching as a career and highly rank teachers, especially science teachers, as having a positive influence on their career path. The qualities of job enjoyment, job stability, and helping others that are characteristic of teaching were also found to be of high importance. Perceptions of the personal, social, professional, and career qualities of a science teacher were found to differ from a scientist. While both science teachers and scientists were found to be responsible, persistent, and productive, science teachers were perceived as being a distinct career possessing qualities that make them more personable, sociable, and wise than scientists. Some gender differences were detected but there was no evidence of gender bias affecting students choosing a career path to science teaching. Science teachers were perceived to be very supportive of females pursuing scientific career paths. The study also found evidence that some introductory level college students steer away from science teaching because of low salary, the lack of promotion, and the efforts of influential people including science teachers. The study calls for departments of science education to take a more active role in the recruitment of new science teachers and the improvement of undergraduate science education.

CESAME: Providing High Quality Professional Development in Science and Mathematics for K-12 Teachers

NASA Astrophysics Data System (ADS)

Hickman, Paul

2002-04-01

It is appropriate that after almost half a century of Science and Mathematics education reform we take a look back and a peek forward to understand the present state of this wonderfully complex system. Each of the components of this system including teaching, professional development, assessment, content and the district K-12 curriculum all need to work together if we hope to provide quality science, mathematics and technology education for ALL students. How do the state and national standards drive the system? How do state policies on student testing and teacher licensure come into play? How do we improve the preparation, retention and job satisfaction of our K-12 teachers? What initiatives have made or are making a difference? What else needs to be done? What can the physics community do to support local efforts? This job is too big for any single organization or individual but we each can contribute to the effort. Our Center at Northeastern University, with support from the National Science Foundation, has a sharply defined focus: to get high quality, research-based instructional materials into the hands of K-12 classroom teachers and provide the support they need to use the materials effectively in their classrooms.

Worms to astronauts: Canadian Space Agency approach to life sciences in support of exploration

NASA Astrophysics Data System (ADS)

Buckley, Nicole; Johnson-Green, Perry; Lefebvre, Luc

As the pace of human exploration of space is accelerated, the need to address the challenges of long-duration human missions becomes imperative. Working with limited resources, we must determine the most effective way to meet this challenge. A great deal of science management centres on "applied" versus "basic" research as the cornerstone of a program. We have chosen to largely ignore such a labeling of science and concentrate on quality, as determined by peer review, as the primary criterion for science selection. Space Life Sciences is a very young science and access to space continues to be difficult. Because we have few opportunities for conducting science, and space life science is very challenging, we are comfortable maintaining a very high bar for selection. In order to ensure adequate depth to our community we have elected to concentrate our efforts. Working in concert with members of the community, we have identified specific areas of focus that are chosen by their importance in space, but also according to Canada's strength in the terrestrial counterpart of the research. It is hoped that through a balanced but highly competitive program with the emphasis on quality, Canadian scientists can contribute to making space a safer, more welcoming place for our astronauts.

Facial appearance affects science communication

Gheorghiu, Ana I.; Callan, Mitchell J.; Skylark, William J.

2017-01-01

First impressions based on facial appearance predict many important social outcomes. We investigated whether such impressions also influence the communication of scientific findings to lay audiences, a process that shapes public beliefs, opinion, and policy. First, we investigated the traits that engender interest in a scientist’s work, and those that create the impression of a “good scientist” who does high-quality research. Apparent competence and morality were positively related to both interest and quality judgments, whereas attractiveness boosted interest but decreased perceived quality. Next, we had members of the public choose real science news stories to read or watch and found that people were more likely to choose items that were paired with “interesting-looking” scientists, especially when selecting video-based communications. Finally, we had people read real science news items and found that the research was judged to be of higher quality when paired with researchers who look like “good scientists.” Our findings offer insights into the social psychology of science, and indicate a source of bias in the dissemination of scientific findings to broader society.

The Blueprint for Change: A National Strategy to Enhance Access to Earth and Space Science Education Resources

NASA Astrophysics Data System (ADS)

Geary, E. E.; Barstow, D.

2001-12-01

Enhancing access to high quality science education resources for teachers, students, and the general public is a high priority for the earth and space science education communities. However, to significantly increase access to these resources and promote their effective use will require a coordinated effort between content developers, publishers, professional developers, policy makers, and users in both formal and informal education settings. Federal agencies, academic institutions, professional societies, informal science centers, the Digital Library for Earth System Education, and other National SMETE Digital Library Projects are anticipated to play key roles in this effort. As a first step to developing a coordinated, national strategy for developing and delivering high quality earth and space science education resources to students, teachers, and the general public, 65 science educators, scientists, teachers, administrators, policy makers, and business leaders met this June in Snowmass, Colorado to create "Earth and Space Science Education 2010: A Blueprint for Change". The Blueprint is a strategy document that will be used to guide Earth and space science education reform efforts in grades K-12 during the next decade. The Blueprint contains specific goals, recommendations, and strategies for coordinating action in the areas of: Teacher Preparation and Professional Development, Curriculum and Materials, Equity and Diversity, Assessment and Evaluation, Public Policy and Systemic Reform, Public and Informal Education, Partnerships and Collaborations, and Technology. If you develop, disseminate, or use exemplary earth and space science education resources, we invite you to review the Blueprint for Change, share it with your colleagues and local science educators, and join as we work to revolutionize earth and space science education in grades K-12.

Bridging the gap with a duel-credit Earth Science course

NASA Astrophysics Data System (ADS)

Van Norden, W.

2011-12-01

College-bound high school students rarely have any exposure to the Earth Sciences. Earth Science may be offered to Middle School students. What is offered in High School, however, is usually a watered-down course offered to the weakest students. Meanwhile, our best and brightest students are steered towards biology, chemistry, and physics, what most schools consider the "real sciences". As a direct result, our population is not literate in the Earth Sciences and few students choose to study the Earth Science in college. One way to counteract this trend is to offer a rigorous capstone Earth Science course to High School Juniors and Seniors. Offering a course does not guarantee enrollment, however. Top science students are too busy taking Advanced Placement courses to consider a non-AP course. For that reason, the best way to lure top students into studying Earth Science is to create a duel-credit course, for which students receive both high school and college credit. A collaboration between high school teachers and college professors can result in a quality Earth Science course that bridges the huge gap that now exists between middle school science and college Earth Science. Harvard-Westlake School has successfully offered a duel-credit course with UCLA, and has created a model that can be used by other schools.

Air Toxics Under the Big Sky is an environmental science outreach/education program that incorporates the Next Generation Science Standards (NGSS) 8 Practices with the goal of promoting knowledge and understanding of authentic scientific research in high school classrooms through air quality research. A quasi-experimental design was used in order to understand: 1) how the program affects student understanding of scientific inquiry and research and 2) how the open inquiry learning opportunities provided by the program increase student interest in science as a career path . Treatment students received instruction related to air pollution (airborne particulate matter), associated health concerns, and training on how to operate air quality testing equipment. They then participated in a yearlong scientific research project in which they developed and tested hypotheses through research of their own design regarding the sources and concentrations of air pollution in their homes and communities. Results from an external evaluation revealed that treatment students developed a deeper understanding of scientific research than did comparison students, as measured by their ability to generate good hypotheses and research designs, and equally expressed an increased interest in pursuing a career in science. These results emphasize the value of and need for authentic science learning opportunities in the modern science classroom.

The WestEd Eisenhower Regional Consortium (WERC) is in its third year of offering two Earth Systems Science On-line Graduate courses from IGES - one for High School teachers, and one for Middle School teachers. These high-quality courses support WERC's commitment to "supporting increased scientific and mathematical literacy among our nation's youth through services and other support aimed at enhancing the efforts of those who provide K-12 science and mathematics education." These courses also support our NSTA-sponsored "Building a Presence for Science" program in California, providing professional development opportunities to help achieve our vision of increased quantity and quality of science education statewide. Our students have included classroom teachers from upper elementary through high school, community college science teachers, and environmental science center staff who provide inservice for teachers. Educators from Hawaii to New Jersey have provided diverse personal experiences of Earth Systems Science events, and add richness to the online discussions. Students have consistently embraced the concept of a systems-based approach to science instruction, commenting on how these courses have forever changed their teaching practices and provided a successful means for engaging and involving their students in scientific inquiry. Through offering these online courses, we have learned valuable lessons about recruitment, retention, team-building, and facilitating discussions for classes with no "face to face" component. This format is both rich and challenging, with teammates from diverse geographic regions and timezones, with a variety of connectivity and accessibility issues. In this third year of offering the courses, we are pleased to have students taking their second course with us, wanting to continue learning content and stragtegies to improve their skills as science teachers.

High Throughput Multispectral Image Processing with Applications in Food Science.

PubMed

Tsakanikas, Panagiotis; Pavlidis, Dimitris; Nychas, George-John

2015-01-01

Recently, machine vision is gaining attention in food science as well as in food industry concerning food quality assessment and monitoring. Into the framework of implementation of Process Analytical Technology (PAT) in the food industry, image processing can be used not only in estimation and even prediction of food quality but also in detection of adulteration. Towards these applications on food science, we present here a novel methodology for automated image analysis of several kinds of food products e.g. meat, vanilla crème and table olives, so as to increase objectivity, data reproducibility, low cost information extraction and faster quality assessment, without human intervention. Image processing's outcome will be propagated to the downstream analysis. The developed multispectral image processing method is based on unsupervised machine learning approach (Gaussian Mixture Models) and a novel unsupervised scheme of spectral band selection for segmentation process optimization. Through the evaluation we prove its efficiency and robustness against the currently available semi-manual software, showing that the developed method is a high throughput approach appropriate for massive data extraction from food samples.

Interviews are conducted with 45 participants, representing three distinct groups: high school students with variable genetics knowledge, college nonscience majors with little genetics knowledge, and college science majors with advanced genetics knowledge. During the interviews, participants advance positions concerning three scenarios dealing with gene therapy and cloning. Arguments are assessed in terms of the number of justifications offered as well as justification quality, based on a five-point rubric. Multivariate analysis of variance results indicate that college science majors outperformed the other groups in terms of justification quality and frequency. Argumentation does not differ among nonscience majors or high school students. Follow-up qualitative analyses of interview responses suggest that all three groups tend to focus on similar, sociomoral themes as they negotiate socially complex, genetic engineering issues, but that the science majors frequently reference specific science content knowledge in the justification of their claims. Results support the Threshold Model of Content Knowledge Transfer, which proposes two knowledge thresholds around which argumentation quality can reasonably be expected to increase. Research and educational implications of these findings are discussed.

This article presents a case study of 10 high-profile Australian research scientists. These scientists are highly committed to engaging with the public. They interact with a wide range of groups in the community, including the traditional media. They are aware that they are seen as representatives of science at a time when the authority of science and scientists is threatened in Australia by controversy around issues such as climate change and vaccination. Through their experiences of interacting with non-scientists, they have developed views about qualities, characteristics and knowledge that contribute to, or inhibit, positive interactions between scientists and non-scientists. Their experiences and insights highlight aspects of contemporary science that are not generally acknowledged in science curricula.

The context and challenges relating to the remaining tropical rainforest are briefly reviewed and the roles which science can play in addressing questions are outlined. Key messages which articles in the special issue, mainly based on projects of the Royal Society South East Asia Rainforest Research Programme (SEARRP), have raised of relevance to policies on land use, land management and REDD+ are then considered. Results from the atmospheric science and hydrology papers, and some of the ecological ones, demonstrate the very high ecosystem service values of rainforest (compared with oil palm) in maintaining high biodiversity, good local air quality, reducing greenhouse emissions, and reducing landslide, flooding and sedimentation consequences of climate change—and hence provide science to underpin the protection of remaining forest, even if degraded and fragmented. Another group of articles test ways of restoring forest quality (in terms of biodiversity and carbon value) or maintaining as high biodiversity and ecological functioning levels as possible via intelligent design of forest zones and fragments within oil palm landscapes. Finally, factors that have helped to enhance the policy relevance of SEARRP projects and dissemination of their results to decision-makers are outlined. PMID:22006974

How to reduce scientific irreproducibility: the 5-year reflection.

PubMed

Fiala, Clare; Diamandis, Eleftherios P

2017-10-26

We discuss in depth six causes of scientific irreproducibility and their ramifications for the clinical sciences: fraud, unfounded papers published by prominent authorities, bias, technical deficiencies, fragmented science and problems with big data. Some proposed methods to combat this problem are briefly described, including an effort to replicate results from some high impact papers and a proposal that authors include detailed preclinical data in papers with supposedly high translational value. We here advocate for a 5-year reflection on papers with seemingly high clinical/translational potential, published alongside the original paper where authors reflect on the quality, reproducibility and impact of their findings. These reflections can be used as a benchmark for credibility, and begin a virtuous cycle of improving the quality of published findings in the literature.

Forensic Science Curriculum for High School Students

NASA Astrophysics Data System (ADS)

Burgess, Christiana J.

Over the last several decades, forensic science---the application of science to civil and criminal legal matters---has become of increasing popularity with the public. The range of disciplines within the field is immense, offering individuals the potential for a unique career, regardless of their specific interests or expertise. In response to this growth, many organizations, both public and private, have recognized the need to create forensic science programs that strive to maintain and enhance the quality of forensic science education. Unfortunately, most of the emphasis placed on developing these materials relates to post-secondary education, and creates a significant lack of forensic science educational materials available in the U.S., especially in Oklahoma. The purpose of this project was to create a high school curriculum that provides the foundation for building a broad, yet comprehensive, overview of the field of forensic science and its associated disciplines. The overall goal was to create and provide course materials to high school teachers in order to increase their knowledge of forensic science such that they are able to teach its disciplines effectively and with accuracy. The Forensic Science Curriculum for High School Students includes sample lesson plans, PowerPoint presentations, and lab activities with step-by-step instructions.

"Replicability and other features of a high-quality science: Toward a balanced and empirical approach": Correction to Finkel et al. (2017).

2017-11-01

Reports an error in "Replicability and other features of a high-quality science: Toward a balanced and empirical approach" by Eli J. Finkel, Paul W. Eastwick and Harry T. Reis ( Journal of Personality and Social Psychology , 2017[Aug], Vol 113[2], 244-253). In the commentary, there was an error in the References list. The publishing year for the 18th article was cited incorrectly as 2016. The in-text acronym associated with this citation should read instead as LCL2017. The correct References list citation should read as follows: LeBel, E. P., Campbell, L., & Loving, T. J. (2017). Benefits of open and high-powered research outweigh costs. Journal of Personality and Social Psychology , 113, 230-243. http://dx.doi.org/10 .1037/pspi0000049. The online version of this article has been corrected. (The following abstract of the original article appeared in record 2017-30567-002.) Finkel, Eastwick, and Reis (2015; FER2015) argued that psychological science is better served by responding to apprehensions about replicability rates with contextualized solutions than with one-size-fits-all solutions. Here, we extend FER2015's analysis to suggest that much of the discussion of best research practices since 2011 has focused on a single feature of high-quality science-replicability-with insufficient sensitivity to the implications of recommended practices for other features, like discovery, internal validity, external validity, construct validity, consequentiality, and cumulativeness. Thus, although recommendations for bolstering replicability have been innovative, compelling, and abundant, it is difficult to evaluate their impact on our science as a whole, especially because many research practices that are beneficial for some features of scientific quality are harmful for others. For example, FER2015 argued that bigger samples are generally better, but also noted that very large samples ("those larger than required for effect sizes to stabilize"; p. 291) could have the downside of commandeering resources that would have been better invested in other studies. In their critique of FER2015, LeBel, Campbell, and Loving (2016) concluded, based on simulated data, that ever-larger samples are better for the efficiency of scientific discovery (i.e., that there are no tradeoffs). As demonstrated here, however, this conclusion holds only when the replicator's resources are considered in isolation. If we widen the assumptions to include the original researcher's resources as well, which is necessary if the goal is to consider resource investment for the field as a whole, the conclusion changes radically-and strongly supports a tradeoff-based analysis. In general, as psychologists seek to strengthen our science, we must complement our much-needed work on increasing replicability with careful attention to the other features of a high-quality science.

Quality Teaching in Science: an Emergent Conceptual Framework

NASA Astrophysics Data System (ADS)

Jordens, J. Zoe; Zepke, Nick

2017-09-01

Achieving quality in higher education is a complex task involving the interrelationship of many factors. The influence of the teacher is well established and has led to some general principles of good teaching. However, less is known about the extent that specific disciplines influence quality teaching. The purposes of the paper are to investigate how quality teaching is perceived in the sciences and from these perceptions to develop for discussion a framework for teaching practice in the sciences. A New Zealand study explored the views of national teaching excellence award winners in science on quality teaching in undergraduate science. To capture all possible views from this expert panel, a dissensus-recognising Delphi method was used together with sensitising concepts based on complexity and wickedity. The emergent conceptual framework for quality teaching in undergraduate science highlighted areas of consensus and areas where there were a variety of views. About the purposes of science and its knowledge base, there was relative consensus, but there was more variable support for values underpinning science teaching. This highlighted the complex nature of quality teaching in science. The findings suggest that, in addition to general and discipline-specific influences, individual teacher values contribute to an understanding of quality in undergraduate science teaching.

Using Art to Teach Students Science Outdoors: How Creative Science Instruction Influences Observation, Question Formation, and Involvement

NASA Astrophysics Data System (ADS)

Cone, Christina Schull

Elementary education has become increasingly divided into subjects and focused on the demand for high math and reading scores. Consequently, teachers spend less time devoted to science and art instruction. However, teaching art and science is crucial to developing creative and rational thinking, especially for observation and questioning skills. In this study, third grade students attending an urban school in Portland, Oregon received instruction of an art strategy using observational and quantifying drawing techniques. This study examines, "Will an art strategy observing the local environment help students make observations and ask questions?" and "In what ways are student learning and perspectives of science affected by the art strategy?" The independent variable is the art strategy developed for this study. There are three dependent variables: quality of student observations, quality of questions, and themes on student learning and perspectives of science. I predicted students would develop strong observation and questioning skills and that students would find the strategy useful or have an increased interest in science. The art scores were high for relevance and detail, but not for text. There were significant correlations between art scores and questions. Interviews revealed three themes: observations create questions, drawing is helpful and challenging, and students connected to science. By examining science through art, students were engaged and created strong observations and questions. Teachers need to balance unstructured drawing time with scaffolding for optimal results. This study provides an integrated science and art strategy that teachers can use outdoors or adapt for the classroom.

Citizen science: a new direction in canine behavior research.

PubMed

Hecht, Julie; Spicer Rice, Eleanor

2015-01-01

Researchers increasingly rely on members of the public to contribute to scientific projects-from collecting or identifying, to analyzing and disseminating data. The "citizen science" model proves useful to many thematically distinctive fields, like ornithology, astronomy, and phenology. The recent formalization of citizen science projects addresses technical issues related to volunteer participation--like data quality--so that citizen scientists can make longstanding, meaningful contributions to scientific projects. Since the late 1990s, canine science research has relied with greater frequency on the participation of the general public, particularly dog owners. These researchers do not typically consider the methods and technical issues that those conducting citizen science projects embrace and continue to investigate. As more canine science studies rely on public input, an in-depth knowledge of the benefits and challenges of citizen science can help produce relevant, high-quality data while increasing the general public's understanding of canine behavior and cognition as well as the scientific process. We examine the benefits and challenges of current citizen science models in an effort to enhance canine citizen science project preparation, execution, and dissemination.

Building community partnerships to implement the new Science and Engineering component of the NGSS

NASA Astrophysics Data System (ADS)

Burke, M. P.; Linn, F.

2013-12-01

Partnerships between science professionals in the community and professional educators can help facilitate the adoption of the Next Generation Science Standards (NGSS). Classroom teachers have been trained in content areas but may be less familiar with the new required Science and Engineering component of the NGSS. This presentation will offer a successful model for building classroom and community partnerships and highlight the particulars of a collaborative lesson taught to Rapid City High School students. Local environmental issues provided a framework for learning activities that encompassed several Crosscutting Concepts and Science and Engineering Practices for a lesson focused on Life Science Ecosystems: Interactions, Energy, and Dynamics. Specifically, students studied local water quality impairments, collected and measured stream samples, and analyzed their data. A visiting hydrologist supplied additional water quality data from ongoing studies to extend the students' datasets both temporally and spatially, helping students to identify patterns and draw conclusions based on their findings. Context was provided through discussions of how science professionals collect and analyze data and communicate results to the public, using an example of a recent bacterial contamination of a local stream. Working with Rapid City High School students added additional challenges due to their high truancy and poverty rates. Creating a relevant classroom experience was especially critical for engaging these at-risk youth and demonstrating that science is a viable career path for them. Connecting science in the community with the problem-solving nature of engineering is a critical component of NGSS, and this presentation will elucidate strategies to help prospective partners maneuver through the challenges that we've encountered. We recognize that the successful implementation of the NGSS is a challenge that requires the support of the scientific community. This partnership represents one model of science and education professionals collaborating to incorporate science and engineering activities into the curriculum.

Factors that contribute to Hispanic English Language Learners' high academic performance in high school science in the Rio Grande Valley of Texas: A multicase study

NASA Astrophysics Data System (ADS)

Elizondo, Antonio

The purpose of this multicase study was to discover factors that contribute to Hispanic English language learners' (ELL) high academic performance in high school science in the Rio Grande Valley of Texas. Participants were high school seniors enrolled in college-level classes who had scored commended on the science exit-level Texas Assessment of Knowledge and Skills and ranked toward the top of their class. One student from each of four different high schools in south Texas were selected to participate. Schools identified students meeting the participant criteria and provided consent documents. In this qualitative research study, students were interviewed on three different dates. Administrators and science teachers were also interviewed for triangulation. Significant findings showed that intrinsic qualities were mainly responsible for factors contributing to high academic performance. Hispanic ELL students need meaningful responsibilities to internalize self-esteem and self-efficacy to realize high academic performance. Self-motivation, a contributing factor, provides students with a positive outlook on high academic performance and the ability to defer more immediate undermining rewards. Students expect to contribute to society by helping others. This helps their self-esteem as well as their self-worth and supports high academic performance. Parental and teacher support are critical for high academic performance. Low socioeconomic status alone is not a causal factor for poor academic performance. School administrations should assign willing and enthusiastic teachers as mentors to target students and provide skills to parents that promote, inspire, and motivate students' intrinsic qualities. Future studies should examine different leadership styles that maximize teachers' ability to influence students' high academic performance. Finally, students should be given guidance in setting career goals and demonstrating that high academic achievement is attainable and beneficial for all students.

The Learning Assistant Model for Science Teacher Recruitment and Preparation

NASA Astrophysics Data System (ADS)

Otero, Valerie

2006-04-01

There is a shortage of high quality physical science teachers in the United States. In 2001, less than 50% of teachers who taught physics held a major or minor in physics or physics education (Neuschatz & McFarling, 2003). Studies point to content knowledge as one of the two factors that is positively correlated with teacher quality. However, those directly responsible for the science content preparation of teachers, specifically science research faculty, are rarely involved in focused efforts to improve teacher quality or to create alternative paths for becoming a teacher. What role should science research faculty play in the recruitment and preparation of science teachers? How might teacher recruitment and preparation be conceived so that science research faculty members' participation in these efforts is not at odds with the traditional scientific research foci of science research departments? To address this issue, we have coupled our teacher recruitment and preparation efforts with our efforts for transforming our large-enrollment, undergraduate science courses. This is achieved through the undergraduate Learning Assistant (LA) program, where talented mathematics and science majors are hired to assist in transforming large enrollment courses to student-centered, collaborative environments. These LAs are the target of our teacher recruitment efforts. Science research faculty, in collaboration with faculty from the school of education have established a community that supports LAs in making decisions to explore K12 teaching as a career option. Fifteen percent of the LAs who have participated in this program have entered teaching credential programs and now plan to become K12 teachers. An added effect of this program is that research faculty have developed skills and knowledge regarding inquiry-based and student-centered pedagogy and theories of student learning. The Learning Assistant program has led to increased subject matter knowledge among learning assistants, increased interest in K-12 teaching as a career, and increased appreciation and understanding of student-centered and inquiry-based learning. Data to support these claims will be presented. Neuschatz, M. & McFarling, M. (2003). Broadning the Base: High School Physics Education at the Turn of a New Century, AIP Report No. R-439.

Cross-cultural perceptions of assessment of selected international science teachers in American high schools

NASA Astrophysics Data System (ADS)

Hutchison, Charles B.; Bailey, Lynne M.

2006-12-01

International high school science teachers are crossing international and cultural borders to teach, raising important issues in education. In this article, we describe the cross-cultural assessment challenges that four international science teachers encountered when they migrated to teach in the United States. These included differences in grade expectations for a given quality of work, the weight given to final examinations, the assessment process, and cut-off scores for letter grades. To become proficient in their new teaching contexts, the participating teachers had to modify (or hybridize) their assessment philosophies and practices in order to conform to the expectations of their new schools. This hybridization process ushered them into what is proposed as the pedagogical imaginary; a transitional space between the "purity" of their native educational conventions and that of their American schools. The implications of these findings are discussed in hopes of improving high school science teaching experiences for international science teachers.

Progress and Setbacks in K-12 Earth and Space Science Education During the Past Decade

NASA Astrophysics Data System (ADS)

Geary, E.; Hoffman, M.; Stevermer, A.; Barstow, D.

2005-12-01

Since publication of the National Science Education Standards in 1996, key Earth and space science concepts have been incorporated into the science education standards in virtually every state. However, the degree to which Earth and space science standards have been implemented in actual classroom curriculum and state science assessments varies greatly from state to state. In a similar vein, the No Child Left Behind legislation calls for a highly qualified teacher in every classroom: in Idaho over 96 percent of high school teachers are certified to teach Earth science, while in Illinois, less than 42 percent of teachers are certified. Furthermore, in some states, like New York, approximately 20 percent of high school students will take introductory Earth science each year, while in other states, like Texas, less than 1 percent of high school students will take introductory Earth science each year. Why do we have this high degree of variability with respect to the teaching and learning of Earth science across the United States? The answer is complex, as there are many institutional, attitudinal, budgetary, and policy factors affecting the teaching of Earth and space sciences. This presentation will summarize data on the current status of Earth and space science education in the United States, discuss where progress has been made and where setbacks have occurred during the past decade, and provide some suggestions and ideas for improving access to high quality Earth and space science education courses, curricula, assessments, and teachers at the state and local level.

Can jurors recognize missing control groups, confounds, and experimenter bias in psychological science?

PubMed

McAuliff, Bradley D; Kovera, Margaret Bull; Nunez, Gabriel

2009-06-01

This study examined the ability of jury-eligible community members (N = 248) to detect internal validity threats in psychological science presented during a trial. Participants read a case summary in which an expert testified about a study that varied in internal validity (valid, missing control group, confound, and experimenter bias) and ecological validity (high, low). Ratings of expert evidence quality and expert credibility were higher for the valid versus missing control group versions only. Internal validity did not influence verdict or ratings of plaintiff credibility and no differences emerged as a function of ecological validity. Expert evidence quality, expert credibility, and plaintiff credibility were positively correlated with verdict. Implications for the scientific reasoning literature and for trials containing psychological science are discussed.

To better understand how mammals adapt to long duration habitation in space, a system for performing rodent experiments on the ISS is under development. Rodent Research-1 is the first flight and will include validation of both on-orbit animal support and tissue preservation. To evaluate plans for on-orbit sample dissection and preservation, we simulated conditions for euthanasia, tissue dissection, and prolonged sample storage on the ISS, and we also developed methods for post-flight dissection and recovery of high quality RNA from multiple tissues following prolonged storage in situ for future science return. Livers and spleens from mice were harvested under conditions that simulated nominal, on-orbit euthanasia and dissection procedures including storage at minus 80 degrees Centigrade for 4 months. The RNA recovered was of high quality (RNA Integrity Number, RNA Integrity Number (RIN) greater than 8) and quantity, and the liver enzyme contents and activities (catalase, glutathione reductase, GAPDH) were similar to positive controls, which were collected under standard laboratory conditions. We also assessed the impact of possible delayed on-orbit dissection scenarios (off-nominal) by dissecting and preserving the spleen (RNA, later) and liver (fast-freezing) at various time points post-euthanasia (from 5 minutes up to 105 minutes). The RNA recovered was of high quality (spleen, RIN greater than 8; liver, RIN greater than 6) and liver enzyme activities were similar to positive controls at all time points, although an apparent decline in select enzyme activities was evident at 105 minutes. Additionally, various tissues were harvested from either intact or partially dissected, frozen carcasses after storage for approximately 2 months; most of the tissues (brain, heart, kidney, eye, adrenal glands and muscle) were of acceptable RNA quality for science return, whereas some tissues (small intestine, bone marrow and bones) were not. These data demonstrate: 1) The protocols developed for future flight experiments will support science return despite delayed preservation post-euthanasia or prolonged storage, and 2) High-quality RNA samples from many different tissues can be recovered by dissection following prolonged storage of the tissue in situ at minus 80 degrees Centigrade. These findings have relevance both to high-value, ground-based experiments when sample collection capability is severely constrained, and to future spaceflight experiments that entail on-orbit sample recovery by the ISS crew.

Factors Influencing Science Content Accuracy in Elementary Inquiry Science Lessons

NASA Astrophysics Data System (ADS)

Nowicki, Barbara L.; Sullivan-Watts, Barbara; Shim, Minsuk K.; Young, Betty; Pockalny, Robert

2013-06-01

Elementary teachers face increasing demands to engage children in authentic science process and argument while simultaneously preparing them with knowledge of science facts, vocabulary, and concepts. This reform is particularly challenging due to concerns that elementary teachers lack adequate science background to teach science accurately. This study examined 81 in-classroom inquiry science lessons for preservice education majors and their cooperating teachers to determine the accuracy of the science content delivered in elementary classrooms. Our results showed that 74 % of experienced teachers and 50 % of student teachers presented science lessons with greater than 90 % accuracy. Eleven of the 81 lessons (9 preservice, 2 cooperating teachers) failed to deliver accurate science content to the class. Science content accuracy was highly correlated with the use of kit-based resources supported with professional development, a preference for teaching science, and grade level. There was no correlation between the accuracy of science content and some common measures of teacher content knowledge (i.e., number of college science courses, science grades, or scores on a general science content test). Our study concluded that when provided with high quality curricular materials and targeted professional development, elementary teachers learn needed science content and present it accurately to their students.

Development of interest in science and interest in teaching elementary science: Influence of informal, school, and inquiry methods course experiences

NASA Astrophysics Data System (ADS)

Bulunuz, Mizrap

Inquiry-based science instruction is a major goal of science education reform. However, there is little research examining how preservice elementary teachers might be motivated to teach through inquiry. This quantitative study was designed to examine the role of background experiences and an inquiry science methods course on interest in science and interest in teaching science. The course included many activities and assignments at varying levels of inquiry, designed to teach content and inquiry methods and to model effective teaching. The study involved analyses of surveys completed by students in the course on their experiences with science before, during, and at the end of the course. The following questions guided the design of this study and analysis of the data: (1) What science background experiences (school, home, and informal education) do participants have and how do those experiences affect initial interest in science? (2) Among the hands-on activities in the methods course, is there a relationship between level of inquiry of the activity and the motivational quality (interesting, fun, and learning) of the activity? (3) Does the course affect participants' interest and attitude toward science? (4) What aspects of the course contribute to participants' interest in teaching science and choice to teach science? Descriptive and inferential analysis of a background survey revealed that participants with high and low initial interest in science differed significantly on remembering about elementary school science and involvement in science related activities in childhood/youth. Analysis of daily ratings of each hands-on activity on motivational qualities (fun, interest, and learning) indicated that there were significant differences in motivational quality of the activities by level of inquiry with higher levels of inquiry rated more positively. Pre/post surveys indicated that participants increased in interest in science and a number of variables reflecting more positive feelings about science and science teaching. Regression analysis found that the best predictors for interest in teaching science were experiencing fun activities in the science methods course followed by the interest participants brought to the course. This study highlights the motivational aspects of the methods course in developing interest in science and interest in teaching science.

Toward a Climate OSSE for NASA Earth Sciences

Leroy, S. S.; Collins, W. D.; Feldman, D.; Field, R. D.; Ming, Y.; Pawson, S.; Sanderson, B.; Schmidt, G. A.

2016-12-01

In the Continuity Study, the National Academy of Sciences advised that future space missions be rated according to five categories: the importance of a well-defined scientific objective, the utility of the observation in addressing the scientific objective, the quality with which the observation can be made, the probability of the mission's success, and the mission's affordability. The importance, probability, and affordability are evaluated subjectively by scientific consensus, by engineering review panels, and by cost models; however, the utility and quality can be evaluated objectively by a climate observation system simulation experiment (COSSE). A discussion of the philosophical underpinnings of a COSSE for NASA Earth Sciences will be presented. A COSSE is built upon a perturbed physics ensemble of a sophisticated climate model that can simulate a mission's prospective observations and its well-defined quantitative scientific objective and that can capture the uncertainty associated with each. A strong correlation between observation and scientific objective after consideration of physical uncertainty leads to a high quality. Persistence of a high correlation after inclusion of the proposed measurement error leads to a high utility. There are five criteria that govern that nature of a particular COSSE: (1) whether the mission's scientific objective is one of hypothesis testing or climate prediction, (2) whether the mission is empirical or inferential, (3) whether the core climate model captures essential physical uncertainties, (4) the level of detail of the simulated observations, and (5) whether complementarity or redundancy of information is to be valued. Computation of the quality and utility is done using Bayesian statistics, as has been done previously for multi-decadal climate prediction conditioned on existing data. We advocate for a new program within NASA Earth Sciences to establish a COSSE capability. Creation of a COSSE program within NASA Earth Sciences will require answers from the climate research community to basic questions, such as whether a COSSE capability should be centralized or de-centralized. Most importantly, the quantified scientific objective of a proposed mission must be defined with extreme specificity for a COSSE to be applied.

In this paper, small diameter InP nanowires with high crystal quality were synthesized through a chemical vapor deposition method. Benefitting from the high crystallinity and large specific surface area of InP nanowires, the simply constructed photodetector demonstrates a high responsivity of up to 1170 A·W-1 and an external quantum efficiency of 2.8×105% with a fast rise time of 110 ms and a fall time of 130 ms, even at low bias of 0.1 V. The effect of back-gate voltage on photoresponse of the device was systematically investigated, confirming that the photocurrent dominates over thermionic and tunneling currents in the whole operation. A mechanism based on energy band theory at the junction between metal and semiconductor was proposed to explain the back-gate voltage dependent performance of the photodetectors. These convincing results indicate that fine InP nanowires will have a brilliant future in smart optoelectronics.

Evaluating Instrument Quality in Science Education: Rasch-based analyses of a Nature of Science test

NASA Astrophysics Data System (ADS)

Neumann, Irene; Neumann, Knut; Nehm, Ross

2011-07-01

Given the central importance of the Nature of Science (NOS) and Scientific Inquiry (SI) in national and international science standards and science learning, empirical support for the theoretical delineation of these constructs is of considerable significance. Furthermore, tests of the effects of varying magnitudes of NOS knowledge on domain-specific science understanding and belief require the application of instruments validated in accordance with AERA, APA, and NCME assessment standards. Our study explores three interrelated aspects of a recently developed NOS instrument: (1) validity and reliability; (2) instrument dimensionality; and (3) item scales, properties, and qualities within the context of Classical Test Theory and Item Response Theory (Rasch modeling). A construct analysis revealed that the instrument did not match published operationalizations of NOS concepts. Rasch analysis of the original instrument-as well as a reduced item set-indicated that a two-dimensional Rasch model fit significantly better than a one-dimensional model in both cases. Thus, our study revealed that NOS and SI are supported as two separate dimensions, corroborating theoretical distinctions in the literature. To identify items with unacceptable fit values, item quality analyses were used. A Wright Map revealed that few items sufficiently distinguished high performers in the sample and excessive numbers of items were present at the low end of the performance scale. Overall, our study outlines an approach for how Rasch modeling may be used to evaluate and improve Likert-type instruments in science education.

Does Elite Sport Degrade Sleep Quality? A Systematic Review.

PubMed

Gupta, Luke; Morgan, Kevin; Gilchrist, Sarah

2017-07-01

Information on sleep quality and insomnia symptomatology among elite athletes remains poorly systematised in the sports science and medicine literature. The extent to which performance in elite sport represents a risk for chronic insomnia is unknown. The purpose of this systematic review was to profile the objective and experienced characteristics of sleep among elite athletes, and to consider relationships between elite sport and insomnia symptomatology. Studies relating to sleep involving participants described on a pre-defined continuum of 'eliteness' were located through a systematic search of four research databases: SPORTDiscus, PubMed, Science Direct and Google Scholar, up to April 2016. Once extracted, studies were categorised as (1) those mainly describing sleep structure/patterns, (2) those mainly describing sleep quality and insomnia symptomatology and (3) those exploring associations between aspects of elite sport and sleep outcomes. The search returned 1676 records. Following screening against set criteria, a total of 37 studies were identified. The quality of evidence reviewed was generally low. Pooled sleep quality data revealed high levels of sleep complaints in elite athletes. Three risk factors for sleep disturbance were broadly identified: (1) training, (2) travel and (3) competition. While acknowledging the limited number of high-quality evidence reviewed, athletes show a high overall prevalence of insomnia symptoms characterised by longer sleep latencies, greater sleep fragmentation, non-restorative sleep, and excessive daytime fatigue. These symptoms show marked inter-sport differences. Two underlying mechanisms are implicated in the mediation of sport-related insomnia symptoms: pre-sleep cognitive arousal and sleep restriction.

Authentic Learning Experiences for Educators through Summer Internships: Revising the DIG Texas Instructional Blueprints

NASA Astrophysics Data System (ADS)

Martinez, A. O.; Bohls-Graham, E.; Jacobs, B. E.; Ellins, K. K.

2014-12-01

Texas teachers have expressed a need for engaging activities for use in high school Earth science courses. With funding from the NSF, geoscience and education faculty from different institutions around the state collaborated with ten Earth science teachers to create five online Earth science instructional blueprints. The work is part of the DIG (Diversity and Innovation for Geosciences) Texas Instructional Blueprint project. A blueprint stitches together nine units for a yearlong Earth science course (scope and sequence). Each unit covers three weeks of teaching and contains lectures, readings, visualizations, lab investigations, learning activities, and other educational materials from credible sources, which are aligned with Texas state science standards for Earth and Space Science and the Earth Science Literacy Principles. Taken together, the collection of activities address the Next Generation Science Standards (NGSS). During summer 2014, three minority-serving secondary teachers completed a six-week internship at The University of Texas Institute for Geophysics (UTIG). As DIG Texas Education Interns, we organized and revised the content of the units, created scaffolding notes, and built blueprints by selecting groups of nine units from the project's current collection of twenty-one units. Because fieldwork is an important element of geoscience learning, we integrated virtual field trips into each unit. We (1) gained expertise in selecting high quality activities that directly correlate with state standards and address the Earth Science Literacy Principles; (2) developed a keen awareness of the value of the NGSS; (3) learned how to navigate through the NGSS website to track the relationships between the Science and Engineering Practices, Disciplinary Core Ideas, and Crosscutting Concepts for Earth science, as well as connections to other disciplines in the same grade level. Collaborating with other secondary Earth science teachers introduced each of us to new teaching practices, allowing us to build relationships that we expect to last for many years. UTIG researchers mentored and introduced us to their research and methodology. In addition, they helped us find high quality activities for the units. In turn, we shared our knowledge of pedagogy and classroom expertise with them.

ASTRO2010 Decadal Survey stated that an advanced large-aperture ultraviolet, optical, near-infrared (UVOIR) telescope is required to enable the next generation of compelling astrophysics and exoplanet science; and, that present technology is not mature enough to affordably build and launch any potential UVOIR mission concept. AMTD is a multiyear effort to develop, demonstrate and mature critical technologies to TRL-6 by 2018 so that a viable flight mission can be proposed to the 2020 Decadal Review. AMTD builds on the state of art (SOA) defined by over 30 years of monolithic & segmented ground & space-telescope mirror technology to mature six key technologies: center dotLarge-Aperture, Low Areal Density, High Stiffness Mirror Substrates: Both (4 to 8 m) monolithic and (8 to 16 m) segmented telescopes require larger and stiffer mirrors. center dotSupport System: Large-aperture mirrors require large support systems to ensure that they survive launch, deploy on orbit, and maintain a stable, undistorted shape. center dotMid/High Spatial Frequency Figure Error: Very smooth mirror is critical for producing high-quality point spread function (PSF) for high contrast imaging. center dotSegment Edges: The quality of segment edges impacts PSF for high-contrast imaging applications, contributes to stray light noise, and affects total collecting aperture. center dotSegment to Segment Gap Phasing: Segment phasing is critical for producing high-quality temporally-stable PSF. center dotIntegrated Model Validation: On-orbit performance is driven by mechanical & thermal stability. Compliance cannot be 100% tested, but relies on modeling. Because we cannot predict the future, AMTD is pursuing multiple design paths to provide the science community with options to enable either large aperture monolithic or segmented mirrors with clear engineering metrics traceable to science requirements

The Maps in Medicine program: An evaluation of the development and implementation of life sciences curriculum

NASA Astrophysics Data System (ADS)

O'Malley, Jennifer

There has been a downward trend in both science proficiency and interest in science in the United States, especially among minority students and students of a disadvantaged background. This has led to a downturn in the number of individuals within these groups considering a career in the sciences or a related field. Studies have identified many potential causes for this problem including the current structure of science curriculum, lack of teacher preparedness, and the lack of quality education and support for those students currently underrepresented in the sciences. Among the solutions to this problem include redesigning the science curriculum, offering high-quality professional development opportunities to teachers, and creating programs to give support to individuals currently underrepresented in the sciences, so that they may have a better chance of pursuing and obtaining a science career. The Maps in Medicine program (MiM) has been designed to incorporate all of the aforementioned solutions and apply them to the current science education problem. The Maps in Medicine (MiM) program was established at the University of Missouri -- Columbia, and is funded by the Howard Hughes Medical Institute. Newly developed MiM curricula and student activities are intended to promote positive attitude changes in those students who are currently underrepresented in Science, Technology, Engineering and Mathematics (STEM) fields, with the program also providing professional development to high school science teachers. It was important to determine if the MiM program's solution to the science education problem has been successful, and so the program evaluation piece was integral. A mixed-methods approach was used to evaluate the MiM program. Formative evaluation results indicated a positive response from teachers and students regarding curriculum and professional development, and student activities. These results have also lead to the identification of appropriate improvements for the program, and will assist with the program's overall goal of national dissemination of MiM curriculum.

Characterization of non-conductive materials using field emission scanning electron microscopy

NASA Astrophysics Data System (ADS)

Cao, Cong; Gao, Ran; Shang, Huayan; Peng, Tingting

2016-01-01

With the development of science and technology, field emission scanning electron microscope (FESEM) plays an important role in nano-material measurements because of its advantages of high magnification, high resolution and easy operation. A high-quality secondary electron image is a significant prerequisite for accurate and precise length measurements. In order to obtain high-quality secondary electron images, the conventional treatment method for non-conductive materials is coating conductive films with gold, carbon or platinum to reduce charging effects, but this method will cover real micro structures of materials, change the sample composition properties and meanwhile introduce a relatively big error to nano-scale microstructure measurements. This paper discusses how to reduce or eliminate the impact of charging effects on image quality to the greatest extent by changing working conditions, such as voltage, stage bias, scanning mode and so on without treatment of coating, to obtain real and high-quality microstructure information of materials.

Multi-Stage Open Peer Review: Scientific Evaluation Integrating the Strengths of Traditional Peer Review with the Virtues of Transparency and Self-Regulation

PubMed Central

Pöschl, Ulrich

2012-01-01

The traditional forms of scientific publishing and peer review do not live up to all demands of efficient communication and quality assurance in today’s highly diverse and rapidly evolving world of science. They need to be advanced and complemented by interactive and transparent forms of review, publication, and discussion that are open to the scientific community and to the public. The advantages of open access, public peer review, and interactive discussion can be efficiently and flexibly combined with the strengths of traditional scientific peer review. Since 2001 the benefits and viability of this approach are clearly demonstrated by the highly successful interactive open access journal Atmospheric Chemistry and Physics (ACP, www.atmos-chem-phys.net) and a growing number of sister journals launched and operated by the European Geosciences Union (EGU, www.egu.eu) and the open access publisher Copernicus (www.copernicus.org). The interactive open access journals are practicing an integrative multi-stage process of publication and peer review combined with interactive public discussion, which effectively resolves the dilemma between rapid scientific exchange and thorough quality assurance. Key features and achievements of this approach are: top quality and impact, efficient self-regulation and low rejection rates, high attractivity and rapid growth, low costs, and financial sustainability. In fact, ACP and the EGU interactive open access sister journals are by most if not all standards more successful than comparable scientific journals with traditional or alternative forms of peer review (editorial statistics, publication statistics, citation statistics, economic costs, and sustainability). The high efficiency and predictive validity of multi-stage open peer review have been confirmed in a series of dedicated studies by evaluation experts from the social sciences, and the same or similar concepts have recently also been adopted in other disciplines, including the life sciences and economics. Multi-stage open peer review can be flexibly adjusted to the needs and peculiarities of different scientific communities. Due to the flexibility and compatibility with traditional structures of scientific publishing and peer review, the multi-stage open peer review concept enables efficient evolution in scientific communication and quality assurance. It has the potential for swift replacement of hidden peer review as the standard of scientific quality assurance, and it provides a basis for open evaluation in science. PMID:22783183

The complexity of lung cancer care mandates interaction between clinicians with different skill sets and practice cultures in the routine delivery of care. Using team science principles and a case-based approach, we exemplify the need for the development of real care teams for patients with lung cancer to foster coordination among the multiple specialists and staff engaged in routine care delivery. Achieving coordinated lung cancer care is a high-priority public health challenge because of the volume of patients, lethality of disease, and well-described disparities in quality and outcomes of care. Coordinating mechanisms need to be cultivated among different types of specialist physicians and care teams, with differing technical expertise and practice cultures, who have traditionally functioned more as coactively working groups than as real teams. Coordinating mechanisms, including shared mental models, high-quality communication, mutual trust, and mutual performance monitoring, highlight the challenge of achieving well-coordinated care and illustrate how team science principles can be used to improve quality and outcomes of lung cancer care. To develop the evidence base to support coordinated lung cancer care, research comparing the effectiveness of a diverse range of multidisciplinary care team approaches and interorganizational coordinating mechanisms should be promoted.

The State of Software for Evolutionary Biology.

Darriba, Diego; Flouri, Tomáš; Stamatakis, Alexandros

2018-05-01

With Next Generation Sequencing data being routinely used, evolutionary biology is transforming into a computational science. Thus, researchers have to rely on a growing number of increasingly complex software. All widely used core tools in the field have grown considerably, in terms of the number of features as well as lines of code and consequently, also with respect to software complexity. A topic that has received little attention is the software engineering quality of widely used core analysis tools. Software developers appear to rarely assess the quality of their code, and this can have potential negative consequences for end-users. To this end, we assessed the code quality of 16 highly cited and compute-intensive tools mainly written in C/C++ (e.g., MrBayes, MAFFT, SweepFinder, etc.) and JAVA (BEAST) from the broader area of evolutionary biology that are being routinely used in current data analysis pipelines. Because, the software engineering quality of the tools we analyzed is rather unsatisfying, we provide a list of best practices for improving the quality of existing tools and list techniques that can be deployed for developing reliable, high quality scientific software from scratch. Finally, we also discuss journal as well as science policy and, more importantly, funding issues that need to be addressed for improving software engineering quality as well as ensuring support for developing new and maintaining existing software. Our intention is to raise the awareness of the community regarding software engineering quality issues and to emphasize the substantial lack of funding for scientific software development.

Joint USGS-CUAHSI Workshop: In Situ Optical Water Quality Sensor Networks; Shepherdstown, West Virginia, 8-10 June 2011; Advanced in situ optical water quality sensors and new techniques for data analysis hold enormous promise for advancing scientific understanding of aquatic systems through measurements of important biogeochemical parameters at the time scales over which they vary. High-frequency and real-time water quality data also provide the opportunity for early warning of water quality deterioration, trend detection, and science-based decision support. However, developing networks of optical sensors in freshwater systems that report reliable and comparable data across and between sites remains a challenge to the research and monitoring community. To address this, the U.S. Geological Survey (USGS) and the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI), convened a 3-day workshop to explore ways to coordinate development of standards and applications for optical sensors, as well as handling, storage, and analysis of the continuous data they produce.

McDonald, Christine V.

2016-08-01

A large body of research has drawn attention to the importance of providing engaging learning experiences in junior secondary science classes, in an attempt to attract more students into post-compulsory science courses. The reality of time and resource constraints, and the high proportion of non-specialist science teachers teaching science, has resulted in an overreliance on more transmissive pedagogical tools, such as textbooks. This study sought to evaluate the usage of junior secondary science textbooks in Australian schools. Data were collected via surveys from 486 schools teaching junior secondary (years 7-10), representing all Australian states and territories. Results indicated that most Australian schools use a science textbook in the junior secondary years, and textbooks are used in the majority of science lessons. The most highly cited reason influencing choice of textbook was layout/colour/illustrations, and electronic technologies were found to be the dominant curricula material utilised, in addition to textbooks, in junior secondary science classes. Interestingly, the majority of respondents expressed high levels of satisfaction with their textbooks, although many were keen to stress the subsidiary role of textbooks in the classroom, emphasising the textbook was `one' component of their teaching repertoire. Importantly, respondents were also keen to stress the benefits of textbooks in supporting substitute teachers, beginning teachers, and non-specialist science teachers; in addition to facilitating continuity of programming and staff support in schools with high staff turnover. Implications from this study highlight the need for high quality textbooks to support teaching and learning in Australian junior secondary science classes.

Coherent quantum control of a quantum bit (qubit) is an important step towards its use in a quantum network. SiV- center in diamond offers excellent physical qualities such as low inhomogeneous broadening, fast photon emission, and a large Debye-Waller factor, while the fast spin manipulation and techniques to extend the spin coherence time are under active investigation. Here, we demonstrate full coherent control over the state of a single SiV- center in a diamond nanopillar using ultrafast optical pulses. The high quality of the chemical vapor deposition grown SiV- centers allows us to coherently manipulate and quasi-resonantly read out the state of the single SiV- center. Moreover, the SiV- centers being coherently controlled are integrated into diamond nanopillar arrays in a site-controlled, individually addressable manner with high yield, low strain, and high spectral stability, which paves the way for scalable on chip optically accessible quantum system in a quantum photonic network.

2015-12-01

The 2007 State of the Carbon Cycle Report (SOCCR) was highly influential in ensuring components of the carbon cycle were accounted for in national policy and related management. However, while SOCCR detailed the significance of North American coastal wetlands, it was not until recently that leading governments began to fully recognized these ecosystems for their carbon sequestration and storage capacity and hence the significant role coastal ecosystems can play in GHG emission reductions strategies, offset mechanisms, coastal management strategies and climate mitigation policy. The new attention on coastal carbon systems has exposed limitations in terms of data availability and data quality, as well as insufficient knowledge of coastal carbon distributions, characteristics and coastal carbon cycle processes. In addition to restricting scientific progress, lack of comprehensive, comparable, and quality-controlled coastal carbon data is hindering progress towards carbon based conservation and coastal management. To directly address those limitations, we are developing a Global Science and Data Network for Coastal "Blue" Carbon, with support from the Carbon Cycle Interagency Working Group. Goals include: • Improving basic and applied science on carbon and GHG cycling in vegetated coastal ecosystems; • Supporting a coastal carbon and associated GHG data archive for use by the science community, coastal and climate practitioners and other data users; • Building the capacity of coastal carbon stakeholders globally to collect and interpret high quality coastal carbon science and data; • Providing a forum and mechanism to promote exchange and collaboration between scientists and coastal carbon data users globally; and • Outreach activities to ensure the best available data are globally accessible and that science is responsive to the needs of coastal managers and policy-makers.

During the summer of 2011, the Mālama Ke Ahupua`a (to care of our watershed) GEARUP summer program provided 25 under-served and under-represented minority public high school students (Hawaiian, part-Hawaiian, Filipino, Pacific Islanders) from Farrington High School (Kalihi, Honolulu) with a hands-on place-based multidiscipline course located within Manoa Valley (Ahupua`a O Kona) with the objective of engaging participants in scientific environmental investigations while exploring Hawaii's linkages between traditional knowledge, culture and science. The 4-week field program enabled students to collect samples along the perennial Manoa Stream and conduct water quality assessments throughout the Manoa watershed. Students collected science quality data from eight different sampling stations by means of field- and laboratory-based quantitative water quality testing equipment and GPS/GIS technology. While earning Hawaii DOE academic credits, students were able to document changes along the stream as related to pollution and urbanization. While conducting the various scientific investigations, students also participated in cultural fieldtrips and activities that highlighted the linkages between historical sustainable watershed uses by native Hawaiian communities, and their connections with natural earth processes. Additionally, students also participated in environmental service-learning projects that highlight the Hawaiian values of laulima (teamwork), mālama (to care for), and imi `ike (to seek knowledge). By contextualizing and merging hands-on place-based earth science inquiry with native Hawaiian traditional knowledge, students experienced the natural-cultural significance of their ahupua`a (watershed). This highlighted the advantages for promoting environmental literacy and geoscience education to under-served and under-represented minority populations in Hawaii from a rich native Hawaiian cultural framework.

The Common Metadata Repository (CMR) is a high-performance, high-quality repository for Earth science metadata records, and serves as the primary way to search NASA's growing 17.5 petabytes of Earth science data holdings. Released in 2015, CMR has the capability to support several different metadata standards already being utilized by NASA's combined network of Earth science data providers, or Distributed Active Archive Centers (DAACs). The Analysis and Review of CMR (ARC) Team located at Marshall Space Flight Center is working to improve the quality of records already in CMR with the goal of making records optimal for search and discovery. This effort entails a combination of automated and manual review, where each NASA record in CMR is checked for completeness, accuracy, and consistency. This effort is highly collaborative in nature, requiring communication and transparency of findings amongst NASA personnel, DAACs, the CMR team and other metadata curation teams. Through the evolution of this project it has become apparent that there is a need to document and report findings, as well as track metadata improvements in a more efficient manner. The ARC team has collaborated with Element 84 in order to develop a metadata curation tool to meet these needs. In this presentation, we will provide an overview of this metadata curation tool and its current capabilities. Challenges and future plans for the tool will also be discussed.

The process of photosynthesis is central to science curriculum at all levels. This article describes an inquiry-based laboratory investigation developed to explore the impact of light quality on photosynthesis and to connect this process to current research on harvesting solar energy, including bioenergy, artificial photosynthesis, and solar cells. This laboratory was used with high-school science teachers who then took this experience back to their classrooms. During this exercise, teachers used an economical spectroradiometer to measure the solar spectrum and relate this to photosynthetic light absorption by determining the quality of light beneath trees. Following this investigation, teachers learned about the plant-inspired dye-sensitized solar cells and constructed one. To connect their light quality investigation to the efficiency of photosynthesis and solar cells, teachers then collected data at locations with varying quality and intensity of light. In sum, this investigation provides a crucial connection between photosynthesis and cutting edge research on solar energy technologies. Our learning experience provides a new instructional model for understanding a little investigated aspect of photosynthesis and connects to authentic scientific research.

I have been involved in research on collaborative activities for improving the quality of teaching and learning high school science. Initially the collaborative activities we researched involved the uses of coteaching and cogenerative dialogue in urban middle and high schools in Philadelphia and New York (currently I have active research sites in New York and Brisbane, Australia). The research not only transformed practices but also produced theories that informed the development of additional collaborative activities and served as interventions for research and creation of heuristics for professional development programs and teacher certification courses. The presentation describes a collage of collaborative approaches to teaching and learning science, including coteaching, cogenerative dialogue, radical listening, critical reflection, and mindful action. For each activity in the collage I provide theoretical frameworks and empirical support, ongoing research, and priorities for the road ahead. I also address methodologies used in the research, illustrating how teachers and students collaborated as researchers in multilevel investigations of teaching and learning and learning to teach that included ethnography, video analysis, and sophisticated analyses of the voice, facial expression of emotion, eye gaze, and movement of the body during classroom interactions. I trace the evolution of studies of face-to-face interactions in science classes to the current focus on emotions and physiological aspects of teaching and learning (e.g., pulse rate, pulse strength, breathing patterns) that relate to science participation and achievement.

Research experiences for science teachers are an important mechanism for increasing classroom teachers' science content knowledge and facility with "real world" research processes. We have developed and implemented a summer scientific research and education workshop model for high school teachers and students which promotes classroom science inquiry projects and produces important research results supporting our overarching scientific agenda. The summer training includes development of a scientific research framework, design and implementation of preliminary studies, extensive field research and training in and access to instruments, measurement techniques and statistical tools. The development and writing of scientific papers is used to reinforce the scientific research process. Using these skills, participants collaborate with scientists to produce research quality data and analysis. Following the summer experience, teachers report increased incorporation of research inquiry in their classrooms and student participation in science fair projects. This workshop format was developed for an NSF Biocomplexity Research program focused on the interaction of urban climates, air quality and human response and can be easily adapted for other scientific research projects.

Despite a prevalence of peer-reviewed scientific research and high-level reports by intergovernmental agencies (e.g., IPCC) that document changes in our climate and consequences for human societies, the public discourse regards these topics as controversial and sensitive. The chasm between scientific-based understanding of climate systems and public understanding can most easily be addressed via high quality, science-based education on these topics. Well-trained and confident educators are required to provide this education. However, climate science and energy awareness are complex topics that are rapidly evolving and have a great potential for controversy. Furthermore, the interdisciplinary nature of climate science further increases the difficulty for teachers to stay abreast of the science and the policy. Research has shown that students and educators alike hold misconceptions about the climate system in general and the causes and effects of climate change in particular. The NSF-funded CLEAN Pathway (http://cleanet.org) as part of the National Science Digital Library (http://www.nsdl.org) strives to address these needs and help educators address misconceptions by providing high quality learning resources and professional development opportunities to support educators of grade levels 6 through 16. The materials focus on teaching climate science and energy use. The scope and framework of the CLEAN Pathway is defined by the Essential Principles of Climate Science (CCSP, 2009) and the Energy Literacy Principles recently developed by the Department of Energy. Following this literacy-based approach, CLEAN helps with developing mental models to address misconceptions around climate science and energy awareness through a number of different avenues. These are: 1) Professional development opportunities for educators - interactive webinars for secondary teachers and virtual workshops for college faculty, 2) A collection of scientifically and pedagogically reviewed, high-quality learning resources on climate and energy topics, 3) Detailed information on effective approaches for teaching climate and energy science for a range of grade levels, and 4) A community support forum (http://iceeonline.org, coordinated by a partner project - Inspiring Climate Education Excellence, ICEE), where educators can exchange information and share advice regarding climate and energy education. In this presentation we focus on our experience coordinating professional development opportunities as well as the "Teaching about Climate and Energy" web pages that are offered through the CLEAN Pathway to show-case how misconceptions can be addressed by educators when teaching or learning about climate and energy topics. Providing educators with a robust foundation of topical knowledge, guiding them through common misconceptions and providing them with a collection of well-vetted learning resources is the approach offered by CLEAN to address student misconceptions of climate and energy topics.

Science NetLinks (SNL), a national program that provides online teacher resources created by the American Association for the Advancement of Science (AAAS), has proven to be a leader among educational resource providers in bringing free, high-quality, grade-appropriate materials to the national teaching community in a format that facilitates classroom integration. Now in its ninth year on the Web, Science NetLinks is part of the MarcoPolo Consortium of Web sites and associated state-based training initiatives that help teachers integrate Internet content into the classroom. SNL is a national presence in the K-12 science education community serving over 700,000 teachers each year, who visit the site at least three times a month. SNL features: High-quality, innovative, original lesson plans aligned to Project 2061 Benchmarks for Science Literacy, Original Internet-based interactives and learning challenges, Reviewed Web resources and demonstrations, Award winning, 60-second audio news features (Science Updates). Science NetLinks has an expansive and growing library of this educational material, aligned and sortable by grade band or benchmark. The program currently offers over 500 lessons, covering 72% of the Benchmarks for Science Literacy content areas in grades K-12. Over the past several years, there has been a strong movement to create online resources that support earth and space science education. Funding for various online educational materials has been available from many sources and has produced a variety of useful products for the education community. Teachers, through the Internet, potentially have access to thousands of activities, lessons and multimedia interactive applications for use in the classroom. But, with so many resources available, it is increasingly more difficult for educators to locate quality resources that are aligned to standards and learning goals. To ensure that the education community utilizes the resources, the material must conform to a format that allows easy understanding, evaluation and integration. Science NetLinks' material has been proven to satisfy these criteria and serve thousands of teachers every year. All online interactive materials that are created by AAAS are aligned to AAAS Project 2061 Benchmarks, which mirror National Science Standards, and are developed based on a rigorous set of criteria. For the purpose of this forum we will provide an overview that explains the need for more of these materials in the earth and space education, a review of the criteria for creating these materials and show examples of online materials created by AAAS that support earth and space science.

The Next Generation Science Standards and A Framework for K-12 Science Education have introduced us to 3-dimensional science instruction. Together, these provide infinite opportunities to generate interesting problems inspiring instruction and motivating student learning. Finding good resources to support 3-dimensional learning is challenging. The Climate Literacy and Energy Awareness Network (CLEAN) as a comprehensive source of high-quality, NGSS-aligned resources that can be quickly and easily searched. Furthermore, teachers new to NGSS are asked to do the following: synthesize high quality, scientifically vetted resources to engage students in relevant phenomena, problems and projects develop place-awareness for where students live and learn encourage data analysis, modeling, and argumentation skills energize students to participate in finding possible solutions to the problems we face. These challenges are intensified when teaching climate science and energy technology, some of the most rapidly changing science and engineering fields. Educators can turn to CLEAN to find scientifically and pedagogically vetted resources to integrate into their lessons. In this presentation, we will introduce the newly developed Harmonics Planning Template, Guidance Videos and Flowchart that guide the development of instructionally-sound, NGSS-style units using the CLEAN collection of resources. To illustrate the process, three example units will be presented: Phenology - a place-based investigation, Debating the Grid - a deliberation on optimal energy grid solutions, and History of Earth's Atmosphere and Oceans - a data-rich collaborative investigation.

High Scope Program (HSP) is a long-term project funded by NSC in Taiwan since 2006. It is designed to elevate the quality of science education by means of incorporating emerging science and technology into the traditional curricula in senior high schools. Quake-Catcher Network (QCN), a distributed computing project initiated by Stanford University and UC Riverside, encourages the volunteers to install the low-cost, novel sensors at home and school to build a seismic network. To meet both needs, we have developed a model curriculum that introduces QCN, earthquake science, and cloud computing into high school classrooms. Through professional development workshops, Taiwan cloud-based earthquake science learning platform, and QCN club on Facebook, we have worked closely with Lan-Yang Girl's Senior High School teachers' team to design workable teaching plans through a practical operation of seismic monitoring at home or school. However, some obstacles to learning appear including QCN installation/maintain problems, high self-noise of the sensor, difficulty of introducing earthquake sciences for high school teachers. The challenges of QCN outreach in Taiwan bring out our future plans: (1) development of easy, frequently updated, physics-based QCN-experiments for high school teachers, and (2) design of an interactive learning platform with social networking function for students.

Science education as a civil right: Urban schools and opportunity-to-learn considerations

NASA Astrophysics Data System (ADS)

Tate, William

2001-11-01

In this article I make the case that urban science education is a civil rights issue and that to effectively address it as such we must shift from arguments for civil rights as shared physical space in schools to demands for high-quality academic preparation that includes the opportunity to learn science. The argument is organized into two sections: first, a review of the school desegregation literature to make the case that urban science education for all is a civil rights issue; and second, an examination and critique of opportunity-to-learn literature, including an analysis of three opportunity-to-learn constructs to illustrate their potential as civil rights tools in science education.

In the United States, it is estimated that 75,000 deaths every year could be averted if the healthcare system implemented high quality care more effectively and efficiently. Patient harm in the hospital occurs as a consequence of inadequate procedures, medications and other therapies, nosocomial infections, diagnostic evaluations and patient falls. Implementation science, a new emerging field in healthcare, is the development and study of methods and tools aimed at enhancing the implementation of new discoveries and evidence into daily healthcare delivery. The Indiana University Center for Healthcare Innovation and Implementation Science (IU-CHIIS) was launched in September 2013 with the mission to use implementation science and innovation to produce great-quality, patient-centered and cost-efficient healthcare delivery solutions for the United States of America. Within the first 24 months of its initiation, the IU-CHIIS successfully scaled up an evidence-based collaborative care model for people with dementia and/or depression, successfully expanded the Accountable Care Unit model positively impacting the efficiency and quality of care, created the first Certificate in Innovation and Implementation Science in the US and secured funding from National Institutes of Health to investigate innovations in dementia care. This article summarizes the establishment of the IU-CHIIS, its impact and outcomes and the lessons learned during the journey. Copyright © 2015. Published by Elsevier GmbH.

Joynson, Catherine; Leyser, Ottoline

2015-01-01

In 2014, the UK-based Nuffield Council on Bioethics carried out a series of engagement activities, including an online survey to which 970 people responded, and 15 discussion events at universities around the UK to explore the culture of research in the UK and its effect on ethical conduct in science and the quality of research. The findings of the project were published in December 2014 and the main points are summarised here. We found that scientists are motivated in their work to find out more about the world and to benefit society, and that they believe collaboration, multidisciplinarity, openness and creativity are important for the production of high quality science. However, in some cases, our findings suggest, the culture of research in higher education institutions does not support or encourage these goals or activities. For example, high levels of competition and perceptions about how scientists are assessed for jobs and funding are reportedly contributing to a loss of creativity in science, less collaboration and poor research practices. The project led to suggestions for action for funding bodies, research institutions, publishers and editors, professional bodies and individual researchers.

The authors have reported their recent progress in the research field of ZnO materials as well as the corresponding global advance. Recent results regarding (1) the development of high-quality epitaxy techniques, (2) the defect physics and the Te/N co-doping mechanism for p-type conduction, and (3) the design, realization, and properties of the ZnMgO/ZnO hetero-structures have been shown and discussed. A complete technology of the growth of high-quality ZnO epi-films and nano-crystals has been developed. The co-doping of N plus an iso-valent element to oxygen has been found to be the most hopeful path to overcome the notorious p-type hurdle. High mobility electrons have been observed in low-dimensional structures utilizing the polarization of ZnMgO and ZnO. Very different properties as well as new physics of the electrons in 2DEG and 3DES have been found as compared to the electrons in the bulk.

How Fit is Your Citizen Science Data?

Data quality and accuracy is a fundamental concern with utilizing citizen science data. Although many methods can be used to assess quality and accuracy, these methods may not be sufficient to qualify citizen science data for widespread use in scientific research. While Data Fitness For Use (DFFU) does not provide a blanket assessment of data quality, it does assesses the data's ability to be used for a specific application, within a given area (Devillers and Bédard 2007). The STAAq (Spatial, Temporal, Aptness, and Accuracy) assessment was developed to assess the fitness for use of citizen science data, this assessment can be used on a stand alone dataset or be used to compare multiple datasets. The citizen science data used in this assessment was collected by volunteers of the Map of Life- Denali project, which is a tourist-centric citizen science project developed through a partnership with Arizona State University, Map of Life at Yale University, and Denali National Park and Preserve. Volunteers use the offline version of the Map of Life app to record their wildlife, insect, and plant observations in the park. To test the STAAq assessment data from different sources- Map of Life- Denali, Ride Observe and Record, and NPS wildlife surveys- were compared to determined which dataset is most fit for use for a specific research question; What is the recent Grizzly bear distribution in areas of high visitor use in Denali National Park and Preserve? These datasets were compared and ranked according to how well they performed in each of the components of the STAAq assessment. These components include spatial scale, temporal scale, aptness, and application. The Map of Life- Denali data and the ROAR program data were most for use for this research question. The STAAq assessment can be adjusted to assess the fitness for use of a single dataset or being used to compare any number of datasets. This data fitness for use assessment provides a means to assess data fitness instead of data quality for citizen science data.

The State of Software for Evolutionary Biology

Darriba, Diego; Flouri, Tomáš; Stamatakis, Alexandros

2018-01-01

Abstract With Next Generation Sequencing data being routinely used, evolutionary biology is transforming into a computational science. Thus, researchers have to rely on a growing number of increasingly complex software. All widely used core tools in the field have grown considerably, in terms of the number of features as well as lines of code and consequently, also with respect to software complexity. A topic that has received little attention is the software engineering quality of widely used core analysis tools. Software developers appear to rarely assess the quality of their code, and this can have potential negative consequences for end-users. To this end, we assessed the code quality of 16 highly cited and compute-intensive tools mainly written in C/C++ (e.g., MrBayes, MAFFT, SweepFinder, etc.) and JAVA (BEAST) from the broader area of evolutionary biology that are being routinely used in current data analysis pipelines. Because, the software engineering quality of the tools we analyzed is rather unsatisfying, we provide a list of best practices for improving the quality of existing tools and list techniques that can be deployed for developing reliable, high quality scientific software from scratch. Finally, we also discuss journal as well as science policy and, more importantly, funding issues that need to be addressed for improving software engineering quality as well as ensuring support for developing new and maintaining existing software. Our intention is to raise the awareness of the community regarding software engineering quality issues and to emphasize the substantial lack of funding for scientific software development.

Initial, science-directed human exploration of Mars will benefit from capabilities in which human explorers remain in orbit to control telerobotic systems on the surface (Figure 1). Low-latency, high-bandwidth telerobotics (LLT) from Mars orbit offers opportunities for what the terrestrial robotics community considers to be high-quality telepresence. Such telepresence would provide high quality sensory perception and situation awareness, and even capabilities for dexterous manipulation as required for adaptive, informed selection of scientific samples [1]. Astronauts on orbit in close communication proximity to a surface exploration site (in order to minimize communication latency) represent a capability that would extend human cognition to Mars (and potentially for other bodies such as asteroids, Venus, the Moon, etc.) without the challenges, expense, and risk of putting those humans on hazardous surfaces or within deep gravity wells. Such a strategy may be consistent with goals for a human space flight program that, are currently being developed within NASA.

The crucial step of most of the current genetic studies is the extraction of DNA of sufficient quantity and quality. Several genomic DNA isolation methods have been described to successfully obtain male DNA from shrimp species. However, all current protocols require invasive handling methods with males for DNA isolation. Using Aristeus antennatus as a model we tested a reliable non-invasive differential DNA extraction method to male DNA isolation from spermatophores attached to female thelycum. The present protocol provides high quality and quantity DNA for polymerase chain reaction amplification and male genotyping. This new approach could be useful to experimental shrimp culture to select sires with relevant genetic patterns for selective breeding programs. More importantly, it can be applied to identify the mating pairs and male structure in wild populations of species as A. antennatus, where males are often difficult to capture. Our method could be also valuable for biological studies on other spermatophore-using species, such as myriapods, arachnids and insects. © 2016 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

A simple fabrication of CH3NH3PbI3 perovskite for solar cells using low-purity PbI2

2017-01-01

The CH3NH3PbI3 (MAPbI3) perovskite was usually prepared by high-purity PbI2 with high cost. The low cost and low-purity PbI2 was seldom reported for fabrication of MAPbI3 because it cannot even dissolve well in widely adopted solvent of DMF. We developed an easy method to adapt low-purity PbI2 for fabrication of high quality MAPbI3 just by the simple addition of some hydrochloric acid into the mixture of low-purity PbI2, MAI and DMF. This straightforward method can not only help dissolve the low quality PbI2 by reacting with some impurities in DMF, but also lead to a successful fabrication of high-quality perovskite solar cells with up to 14.80% efficiency comparable to the high quality PbI2 precursors.

Data from well-designed experiments provide the strongest evidence of causation in biodiversity studies. However, for many species the collection of these data is not scalable to the spatial and temporal extents required to understand patterns at the population level. Only data collected from citizen science projects can gather sufficient quantities of data, but data collected from volunteers are inherently noisy and heterogeneous. Here we describe a 'Big Data' approach to improve the data quality in eBird, a global citizen science project that gathers bird observations. First, eBird's data submission design ensures that all data meet high standards of completeness and accuracy. Second, we take a 'sensor calibration' approach to measure individual variation in eBird participant's ability to detect and identify birds. Third, we use species distribution models to fill in data gaps. Finally, we provide examples of novel analyses exploring population-level patterns in bird distributions.

2014-01-01

Geostationary Coastal and Air pollution Events (GEO-CAPE) is a NASA decadal survey mission to be designed to provide surface reflectance at high spectral, spatial, and temporal resolutions from a geostationary orbit necessary for studying regional-scale air quality issues and their impact on global atmospheric composition processes. GEO-CAPE's Atmospheric Science Questions explore the influence of both gases and particles on air quality, atmospheric composition, and climate. The objective of the GEO-CAPE Observing System Simulation Experiment (OSSE) is to analyze the sensitivity of ozone to the global and regional NOx emissions and improve the science impact of GEO-CAPE with respect to the global air quality. The GEO-CAPE OSSE team at Jet propulsion Laboratory has developed a comprehensive OSSE framework that can perform adjoint-sensitivity analysis for a wide range of observation scenarios and measurement qualities. This report discusses the OSSE framework and presents the sensitivity analysis results obtained from the GEO-CAPE OSSE framework for seven observation scenarios and three instrument systems.

Research evaluation is a systematic and objective process to measure relevance, efficiency and effectiveness of research activities, and peer review is one of the most important tools for assessing quality of research. The aim of this study was introducing research evaluation indicators based on peer reviewing. This study was implemented in 4 stages. A list of objective-oriented evaluation indicators were designed in 4 axes, including; governance and leadership, structure, knowledge production and research impact. The top 10% medical sciences research centers (RCs) were evaluated based on peer review. Adequate equipment and laboratory instruments, high quality research publication and national or international cooperation were the main strengths in medical sciences RCs and the most important weaknesses included failure to adhere to strategic plans, parallel actions in similar fields, problems in manpower recruitment, knowledge translation & exchange (KTE) in service providers and policy makers' levels. Peer review evaluation can improve the quality of research.

2013-01-01

Here we present the first empirical evidence to support the hypothesis that a gender-heterogeneous problem-solving team generally produced journal articles perceived to be higher quality by peers than a team comprised of highly-performing individuals of the same gender. Although women were historically underrepresented as principal investigators of working groups, their frequency as PIs at the National Center for Ecological Analysis and Synthesis is now comparable to the national frequencies in biology and they are now equally qualified, in terms of their impact on the accumulation of ecological knowledge (as measured by the h-index). While women continue to be underrepresented as working group participants, peer-reviewed publications with gender-heterogeneous authorship teams received 34% more citations than publications produced by gender-uniform authorship teams. This suggests that peers citing these publications perceive publications that also happen to have gender-heterogeneous authorship teams as higher quality than publications with gender uniform authorship teams. Promoting diversity not only promotes representation and fairness but may lead to higher quality science.

Schneider, Barbara St Pierre; Nicholas, Jennifer; Kurrus, Jeffrey E

2013-01-01

To compare the methodologic quality and study/report characteristics between quantitative clinical nursing and nursing education research articles. The methodologic quality of quantitative nursing education research needs to advance to a higher level. Clinical research can provide guidance for nursing education to reach this level. One hundred quantitative clinical research articles from-high impact journals published in 2007 and 37 education research articles from high impact journals published in 2006 to 2007 were chosen for analysis. Clinical articles had significantly higher quality scores than education articles in three domains: number of institutions studied, type of data, and outcomes. The findings indicate three ways in which nursing education researchers can strengthen the methodologic quality of their quantitative research. With this approach, greater funding may be secured for advancing the science of nursing education.

For a 'user' there are several genres of citizen science activities one can enlist themselves in, from microtasked analytics to data collection. Often times design conversation for these efforts are focused around the goal of collecting high quality data for an urgent scientific question. However, there is much to be discussed around the opportunity to expand upon the interaction experience of the 'user'. This is particularly relevant in the integration of citizen science in the classroom. Here we explore the role of citizen science in formal K-12 science education through the lens of "Project Based Learning", examining design challenges in classroom adoption (including standards alignment) as well as interaction design focused around long term user/student motivation and engagement in the science exploration.

The objective of the NASA's Suomi National Polar Orbiting Partnership (S-NPP) Land Science Investigator-led Processing System (Land SIPS), housed at the NASA Goddard Space Flight Center (GSFC), is to produce high quality land products from the Visible Infrared Imaging Radiometer Suite (VIIRS) to extend the Earth System Data Records (ESDRs) developed from NASA's heritage Earth Observing System (EOS) Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the EOS Terra and Aqua satellites. In this paper we will present the functional description and capabilities of the S-NPP Land SIPS, including system development phases and production schedules, timeline for processing, and delivery of land science products based on coordination with the S-NPP Land science team members. The Land SIPS processing stream is expected to be operational by December 2016, generating land products either using the NASA science team delivered algorithms, or the "best-of" science algorithms currently in operation at NASA's Land Product Evaluation and Algorithm Testing Element (PEATE). In addition to generating the standard land science products through processing of the NASA's VIIRS Level 0 data record, the Land SIPS processing system is also used to produce a suite of near-real time products for NASA's application community. Land SIPS will also deliver the standard products, ancillary data sets, software and supporting documentation (ATBDs) to the assigned Distributed Active Archive Centers (DAACs) for archival and distribution. Quality assessment and validation will be an integral part of the Land SIPS processing system; the former being performed at Land Data Operational Product Evaluation (LDOPE) facility, while the latter under the auspices of the CEOS Working Group on Calibration & Validation (WGCV) Land Product Validation (LPV) Subgroup; adopting the best-practices and tools used to assess the quality of heritage EOS-MODIS products generated at the MODIS Adaptive Processing System (MODAPS).

Why are modern scientists so dull? How science selects for perseverance and sociability at the expense of intelligence and creativity.

PubMed

Charlton, Bruce G

2009-03-01

why are so many leading modern scientists so dull and lacking in scientific ambition? because the science selection process ruthlessly weeds-out interesting and imaginative people. At each level in education, training and career progression there is a tendency to exclude smart and creative people by preferring Conscientious and Agreeable people. The progressive lengthening of scientific training and the reduced independence of career scientists have tended to deter vocational 'revolutionary' scientists in favour of industrious and socially adept individuals better suited to incremental 'normal' science. High general intelligence (IQ) is required for revolutionary science. But educational attainment depends on a combination of intelligence and the personality trait of Conscientiousness; and these attributes do not correlate closely. Therefore elite scientific institutions seeking potential revolutionary scientists need to use IQ tests as well as examination results to pick-out high IQ 'under-achievers'. As well as high IQ, revolutionary science requires high creativity. Creativity is probably associated with moderately high levels of Eysenck's personality trait of 'Psychoticism'. Psychoticism combines qualities such as selfishness, independence from group norms, impulsivity and sensation-seeking; with a style of cognition that involves fluent, associative and rapid production of many ideas. But modern science selects for high Conscientiousness and high Agreeableness; therefore it enforces low Psychoticism and low creativity. Yet my counter-proposal to select elite revolutionary scientists on the basis of high IQ and moderately high Psychoticism may sound like a recipe for disaster, since resembles a formula for choosing gifted charlatans and confidence tricksters. A further vital ingredient is therefore necessary: devotion to the transcendental value of Truth. Elite revolutionary science should therefore be a place that welcomes brilliant, impulsive, inspired, antisocial oddballs - so long as they are also dedicated truth-seekers.

Fit for purpose quality management system for military forensic exploitation.

2018-03-01

In a previous publication we described a systems approach to forensic science applied in the military domain. The forensic science 'system of systems' describes forensic science as a sub-system in the larger criminal justice, law enforcement, intelligence, and military systems, with quality management being an important supporting system. Quality management systems help to ensure that organisations achieve their objective and continually improve their capability. Components of forensic science quality management systems can include standardisation of processes, accreditation of facilities to national/international standards, and certification of personnel. A fit for purpose quality management system should be balanced to allow organisations to meet objectives, provide continuous improvement; mitigate risk; and impart a positive quality culture. Considerable attention over the last decades has been given to the need for forensic science quality management systems to meet criminal justice and law enforcement objectives. More recently, the need for the forensic quality management systems to meet forensic intelligence objectives has been considered. This paper, for the first time, discusses the need for a fit for purpose quality management system for military forensic exploitation. Crown Copyright © 2018. Published by Elsevier B.V.

U.S. Geological Survey Fundamental Science Practices

USGS Publications Warehouse

,

2011-01-01

The USGS has a long and proud tradition of objective, unbiased science in service to the Nation. A reputation for impartiality and excellence is one of our most important assets. To help preserve this vital asset, in 2004 the Executive Leadership Team (ELT) of the USGS was charged by the Director to develop a set of fundamental science practices, philosophical premises, and operational principles as the foundation for all USGS research and monitoring activities. In a concept document, 'Fundamental Science Practices of the U.S. Geological Survey', the ELT proposed 'a set of fundamental principles to underlie USGS science practices.' The document noted that protecting the reputation of USGS science for quality and objectivity requires the following key elements: - Clearly articulated, Bureau-wide fundamental science practices. - A shared understanding at all levels of the organization that the health and future of the USGS depend on following these practices. - The investment of budget, time, and people to ensure that the USGS reputation and high-quality standards are maintained. The USGS Fundamental Science Practices (FSP) encompass all elements of research investigations, including data collection, experimentation, analysis, writing results, peer review, management review, and Bureau approval and publication of information products. The focus of FSP is on how science is carried out and how products are produced and disseminated. FSP is not designed to address the question of what work the USGS should do; that is addressed in USGS science planning handbooks and other documents. Building from longstanding existing USGS policies and the ELT concept document, in May 2006, FSP policies were developed with input from all parts of the organization and were subsequently incorporated into the Bureau's Survey Manual. In developing an implementation plan for FSP policy, the intent was to recognize and incorporate the best of USGS current practices to obtain the optimum overall program for our science. In January 2009, the USGS moved to full implementation of FSP. The FSP Advisory Committee (FSPAC) was formed to serve as the Bureau's working and standing committee to ensure the objectivity and quality of the Bureau's science information products and to provide support for the full implementation of FSP.

University and Elementary School Perspectives of Ideal Elementary Science Teacher Knowledge, Skills, and Dispositions

NASA Astrophysics Data System (ADS)

Sewart, Bethany Bianca

Teacher education knowledge, skills, and dispositions have recently become a well-discussed topic among education scholars around the nation, mainly due to its attention by the National Council for Accreditation of Teacher Education (NCATE) over the past few years. Accrediting agencies, such as NCATE and the Interstate New Teacher and Assessment and Support Consortium (INTASC), have sought to improve the quality of teacher education programs by examining knowledge, skills, and dispositions as factors in preparing highly-qualified teachers. There is a paucity of research examining these factors for elementary science teachers. Because these factors influence instruction, and students are behind in scientific and mathematical knowledge, elementary science teachers should be studied. Teacher knowledge, skills, and dispositions should be further researched in order to ultimately increase the quality of teachers and teacher education programs. In this particular case, by determining what schools of education and public schools deem important knowledge, skills, and dispositions needed to teach science, higher education institutions and schools can collaborate to further educate these students and foster the necessary qualities needed to teach effectively. The study of knowledge, skills, and dispositions is crucial to nurturing effective teaching within the classroom. Results from this study demonstrated that there were prominent knowledge, skills, and dispositions identified by teachers, administrators, and science teacher educators as important for effective teaching of elementary science. These characteristics included: a willingness to learn, or open-mindedness; content knowledge; planning, organization, and preparation; significance of teaching science; and science-related assessment strategies. Interestingly, administrators in the study responded differently than their counterparts in the following areas: their self-evaluation of teacher effectiveness; how the teaching of science is valued; the best approach to science teaching; and planning for science instruction. When asked of their teaching effectiveness while teaching science, principals referred to enjoying science teaching and improving their practice, while teachers and science teacher educators discussed content knowledge. Administrators valued conducting experiments and hands-on science while teaching science, while their educational counterparts valued creating student connections and providing real-life applications to science for students. In their professional opinions, administrators preferred a hands-on approach to science teaching. Teachers and science teacher educators stated that they view scientific inquiry, exploration, and discovery as effective approaches to teaching within their classrooms. Administrators predicted that teachers would state that lack of resources affects their lesson planning in science. However, teachers and science teacher educators asserted that taking time to plan for science instruction was most important.

Putnam, James E.; Hansen, Cristi V.

2014-01-01

As the Nation’s principle earth-science information agency, the U.S. Geological Survey (USGS) is depended on to collect data of the highest quality. This document is a quality-assurance plan for groundwater activities (GWQAP) of the Kansas Water Science Center. The purpose of this GWQAP is to establish a minimum set of guidelines and practices to be used by the Kansas Water Science Center to ensure quality in groundwater activities. Included within these practices are the assignment of responsibilities for implementing quality-assurance activities in the Kansas Water Science Center and establishment of review procedures needed to ensure the technical quality and reliability of the groundwater products. In addition, this GWQAP is intended to complement quality-assurance plans for surface-water and water-quality activities and similar plans for the Kansas Water Science Center and general project activities throughout the USGS. This document provides the framework for collecting, analyzing, and reporting groundwater data that are quality assured and quality controlled. This GWQAP presents policies directing the collection, processing, analysis, storage, review, and publication of groundwater data. In addition, policies related to organizational responsibilities, training, project planning, and safety are presented. These policies and practices pertain to all groundwater activities conducted by the Kansas Water Science Center, including data-collection programs, interpretive and research projects. This report also includes the data management plan that describes the progression of data management from data collection to archiving and publication.

Image Quality Assessment of JPEG Compressed Mars Science Laboratory Mastcam Images using Convolutional Neural Networks

NASA Astrophysics Data System (ADS)

Kerner, H. R.; Bell, J. F., III; Ben Amor, H.

2017-12-01

The Mastcam color imaging system on the Mars Science Laboratory Curiosity rover acquires images within Gale crater for a variety of geologic and atmospheric studies. Images are often JPEG compressed before being downlinked to Earth. While critical for transmitting images on a low-bandwidth connection, this compression can result in image artifacts most noticeable as anomalous brightness or color changes within or near JPEG compression block boundaries. In images with significant high-frequency detail (e.g., in regions showing fine layering or lamination in sedimentary rocks), the image might need to be re-transmitted losslessly to enable accurate scientific interpretation of the data. The process of identifying which images have been adversely affected by compression artifacts is performed manually by the Mastcam science team, costing significant expert human time. To streamline the tedious process of identifying which images might need to be re-transmitted, we present an input-efficient neural network solution for predicting the perceived quality of a compressed Mastcam image. Most neural network solutions require large amounts of hand-labeled training data for the model to learn the target mapping between input (e.g. distorted images) and output (e.g. quality assessment). We propose an automatic labeling method using joint entropy between a compressed and uncompressed image to avoid the need for domain experts to label thousands of training examples by hand. We use automatically labeled data to train a convolutional neural network to estimate the probability that a Mastcam user would find the quality of a given compressed image acceptable for science analysis. We tested our model on a variety of Mastcam images and found that the proposed method correlates well with image quality perception by science team members. When assisted by our proposed method, we estimate that a Mastcam investigator could reduce the time spent reviewing images by a minimum of 70%.

To better understand how mammals adapt to long duration habitation in space, a system for performing rodent experiments on the ISS is under development; Rodent Research-1 is the first flight and will include validation of both on-orbit animal support and tissue preservation. To evaluate plans for on-orbit sample dissection and preservation, we simulated conditions for euthanasia, tissue dissection, and prolonged sample storage on the ISS, and we also developed methods for post-flight dissection and recovery of high quality RNA from multiple tissues following prolonged storage in situ for future science. Mouse livers and spleens were harvested under conditions that simulated nominal, on-orbit euthanasia and dissection operations including storage at -80 C for 4 months. The RNA recovered was of high quality (RNA Integrity Number, RIN(is) greater than 8) and quantity, and the liver enzyme contents and activities (catalase, glutathione reductase, GAPDH) were similar to positive controls, which were collected under standard laboratory conditions. We also assessed the impact of possible delayed on-orbit dissection scenarios (off-nominal) by dissecting and preserving the spleen (RNAlater) and liver (fast-freezing) at various time points post-euthanasia (from 5 min up to 105 min). The RNA recovered was of high quality (spleen, RIN (is) greater than 8; liver, RIN (is) greater than 6) and liver enzyme activities were similar to positive controls at all time points, although an apparent decline in select enzyme activities was evident at the latest time (105 min). Additionally, various tissues were harvested from either intact or partially dissected, frozen carcasses after storage for approximately 2 months; most of the tissues (brain, heart, kidney, eye, adrenal glands and muscle) were of acceptable RNA quality for science return, whereas some tissues (small intestine, bone marrow and bones) were not. These data demonstrate: 1) The protocols developed for future flight experiments will support science return despite delayed preservation post-euthanasia or prolonged storage, and 2) Many additional tissues for gene expression analysis can be obtained by dissection following prolonged storage of the tissue in situ at -80 C. These findings have relevance both to high value, ground-based experiments when sample collection capability is severely constrained, and to all future spaceflight experiments that entail on-orbit sample recovery by the ISS crew.

Using Cogenerative Dialogs to Improve Science Teaching and Learning: Challenges and Solutions in High School Students' Internships

NASA Astrophysics Data System (ADS)

Hsu, Pei-Ling

2018-05-01

Internships in science research settings have received increasing attention as a means of helping students construct appropriate understandings, practices, tools, and language in scientific activities. To advance student-scientist partnerships beyond the status quo, the study aimed to investigate how cogenerative dialogs (cogens) may help high school students and scientists identify and address challenges collectively. The analysis identified nine major challenges discussed during cogens: (1) the quality and progress of scientific practice in laboratories, (2) the quality of scientists'/assistants' instructions in classrooms, (3) the quality of student participation in classrooms and homework, (4) students' absences, including arriving late or leaving early, (5) the quality of administrative support, (6) preparation for scientific presentations, (7) the process of deciding project topics, (8) students' peer interactions and communication, and (9) students' physiological needs. The three most salient challenges were "the quality and progress of scientific practice in laboratories" (39%), "the quality of scientists'/assistants' instructions in classrooms" (20%), and "the quality of student participation in classrooms and homework" (17%). The study shows that cogens allowed students and scientists to agree on teaching modifications that positively influenced teaching and learning processes during the internship, such that issues were reduced from the beginning to the closing stages. Importantly, the challenges and solutions identified by students and scientists in this study provide accounts of first-hand experience as well as insights to aid program directors or coordinators in designing a learning environment that can foster effective practice for internships by avoiding the issues identified in the study.

Cardiopulmonary resuscitation quality: [corrected] improving cardiac resuscitation outcomes both inside and outside the hospital: a consensus statement from the American Heart Association.

The "2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care" increased the focus on methods to ensure that high-quality cardiopulmonary resuscitation (CPR) is performed in all resuscitation attempts. There are 5 critical components of high-quality CPR: minimize interruptions in chest compressions, provide compressions of adequate rate and depth, avoid leaning between compressions, and avoid excessive ventilation. Although it is clear that high-quality CPR is the primary component in influencing survival from cardiac arrest, there is considerable variation in monitoring, implementation, and quality improvement. As such, CPR quality varies widely between systems and locations. Victims often do not receive high-quality CPR because of provider ambiguity in prioritization of resuscitative efforts during an arrest. This ambiguity also impedes the development of optimal systems of care to increase survival from cardiac arrest. This consensus statement addresses the following key areas of CPR quality for the trained rescuer: metrics of CPR performance; monitoring, feedback, and integration of the patient's response to CPR; team-level logistics to ensure performance of high-quality CPR; and continuous quality improvement on provider, team, and systems levels. Clear definitions of metrics and methods to consistently deliver and improve the quality of CPR will narrow the gap between resuscitation science and the victims, both in and out of the hospital, and lay the foundation for further improvements in the future.

Effectiveness of an Asynchronous Online Module on University Students' Understanding of the Bohr Model of the Hydrogen Atom

NASA Astrophysics Data System (ADS)

Farina, William J.; Bodzin, Alec M.

2017-12-01

Web-based learning is a growing field in education, yet empirical research into the design of high quality Web-based university science instruction is scarce. A one-week asynchronous online module on the Bohr Model of the atom was developed and implemented guided by the knowledge integration framework. The unit design aligned with three identified metaprinciples of science learning: making science accessible, making thinking visible, and promoting autonomy. Students in an introductory chemistry course at a large east coast university completed either an online module or traditional classroom instruction. Data from 99 students were analyzed and results showed significant knowledge growth in both online and traditional formats. For the online learning group, findings revealed positive student perceptions of their learning experiences, highly positive feedback for online science learning, and an interest amongst students to learn chemistry within an online environment.

International teachers negotiating 21st century science classrooms: a question of hybridized identities and pedagogical imaginaries

NASA Astrophysics Data System (ADS)

Tippins, Deborah J.; Hammond, Lorie; Hutchison, Charles B.

2006-12-01

International high school science teachers are crossing international and cultural borders to teach, raising important issues in education. In this article, we describe the cross-cultural assessment challenges that four international science teachers encountered when they migrated to teach in the United States. These included differences in grade expectations for a given quality of work, the weight given to final examinations, the assessment process, and cutoff scores for letter grades. To become proficient in their new teaching contexts, the participating teachers had to modify (or hybridize) their assessment philosophies and practices in order to conform to the expectations of their new schools. This hybridization process ushered them into what is proposed as the Pedagogical imaginary; a transitional space between the ``purity'' of their native educational conventions and that of their American schools. The implications of these findings are discussed in hopes of improving high school science teaching experiences for international science teachers.

The Dark Matter Particle Explorer (DAMPE) is a high energy particle physics experiment satellite, launched on 17 Dec 2015. The science data processing and payload operation maintenance for DAMPE will be provided by the DAMPE Scientific Application System (SAS) at the Purple Mountain Observatory (PMO) of Chinese Academy of Sciences. SAS is consisted of three subsystems - scientific operation subsystem, science data and user management subsystem and science data processing subsystem. In cooperation with the Ground Support System (Beijing), the scientific operation subsystem is responsible for proposing observation plans, monitoring the health of satellite, generating payload control commands and participating in all activities related to payload operation. Several databases developed by the science data and user management subsystem of DAMPE methodically manage all collected and reconstructed science data, down linked housekeeping data, payload configuration and calibration data. Under the leadership of DAMPE Scientific Committee, this subsystem is also responsible for publication of high level science data and supporting all science activities of the DAMPE collaboration. The science data processing subsystem of DAMPE has already developed a series of physics analysis software to reconstruct basic information about detected cosmic ray particle. This subsystem also maintains the high performance computing system of SAS to processing all down linked science data and automatically monitors the qualities of all produced data. In this talk, we will describe all functionalities of whole DAMPE SAS system and show you main performances of data processing ability.

2008-12-01

The Earth System Science Education Alliance (ESSEA) is a National Science Foundation-supported program implemented by the Institute for Global Environmental Strategies (IGES) to improve the quality of geoscience instruction for pre-service, middle, and high school teachers. ESSEA increases teachers' access to quality materials, standards-based instructional methods and content knowledge. With additional support from NASA, the ESSEA program is being enhanced to reflect emphasis on the International Polar Year. From 1999-2005 the ESSEA program was based on a trio of online courses (for elementary, middle, and high school teachers), the courses have been used by 40 faculty at 20 institutions educating over 1,700 teachers in Earth system science. Program evaluation of original course participants indicated that the courses had significant impact on teachers Earth system content knowledge and beliefs about teaching and learning. Seventeen of the original participating institutions have continued to use the courses and many have developed new programs that incorporate the courses in Earth science education opportunities for teachers. Today the ESSEA program lists nearly 40 colleges and universities as participants. With NASA support, the K-4 course and modules have been revised to include topics and resources focusing on the International Polar Year. Additional modules examining the changes in black carbon, ice sheets and permafrost have been added for middle and high school levels. The new modules incorporate geoscience data and analysis tools into classroom instruction. By exploring IPY related topics and data, participating teachers and their students will develop new understandings about the interactions and dependencies of the Earth spheres and our polar regions. Changes in climate, air, water, and land quality and animal and plant populations make the news everyday. The ESSEA IPY modules will help teachers inform rather than frighten their students as they learn more about the characteristics and importance of our polar regions. One goal of IPY 2007-2008 is to increase the awareness, understanding and interest of school-age children in polar conditions and research. The inclusion of polar topics in the ESSEA courses and modules contributes to the achievement of that goal.

Enabling the Usability of Earth Science Data Products and Services by Evaluating, Describing, and Improving Data Quality throughout the Data Lifecycle

NASA Astrophysics Data System (ADS)

Downs, R. R.; Peng, G.; Wei, Y.; Ramapriyan, H.; Moroni, D. F.

2015-12-01

Earth science data products and services are being used by representatives of various science and social science disciplines, by planning and decision-making professionals, by educators and learners ranging from primary through graduate and informal education, and by the general public. The diversity of users and uses of Earth science data is gratifying and offers new challenges for enabling the usability of these data by audiences with various purposes and levels of expertise. Users and other stakeholders need capabilities to efficiently find, explore, select, and determine the applicability and suitability of data products and services to meet their objectives and information needs. Similarly, they need to be able to understand the limitations of Earth science data, which can be complex, especially when considering combined or simultaneous use of multiple data products and services. Quality control efforts of stakeholders, throughout the data lifecycle, can contribute to the usability of Earth science data to meet the needs of diverse users. Such stakeholders include study design teams, data producers, data managers and curators, archives, systems professionals, data distributors, end-users, intermediaries, sponsoring organizations, hosting institutions, and others. Opportunities for engaging stakeholders to review, describe, and improve the quality of Earth science data products and services throughout the data lifecycle are identified and discussed. Insight is shared from the development of guidelines for implementing the Group on Earth Observations (GEO) Data Management Principles, the recommendations from the Earth Science Data System Working Group (ESDSWG) on Data Quality, and the efforts of the Information Quality Cluster of the Federation of Earth Science Information Partners (ESIP). Examples and outcomes from quality control efforts of data facilities, such as scientific data centers, that contribute to the usability of Earth science data also are offered.

Citizen Science: Broadening Access and Engagement Through Community Partnerships, Aerospace Education and Water Quality Research

NASA Astrophysics Data System (ADS)

Johnson, M. A.

2016-12-01

We applied a new approach to the design and development of citizen science learning opportunities to enhance outreach to diverse student populations, while advancing water quality research and aerospace education. This collaborative approach to informal science, technology, engineering, and math (STEM) and aerospace education required innovative partnerships between private general aviation pilots, researchers, teachers, and students. This research explored the development of active partnerships required to facilitate community engaged science, with an emphasis on increased participation of women and girls and people of color, while creating new exploratory pathways for broadening access to and engagement in STEM learning experiences. We developed an outreach program through collaborative planning with local schools to create new STEM learning experiences based upon basic aerospace education concepts and an existing water quality research project designed to track harmful algal blooms (HAB) that can produce toxins called cyanobacteria, also known as blue-green algae, which can impact drinking, fishing, and recreational waters. General aviation pilots functioning as citizen scientists obtained high-resolution aerial images while flying over potentially impacted waters. Aerial data was made available to teachers and students, as well as researchers participating in the existing water quality program lead by NASA Glenn Research Center. Teachers used the images and results to educate in climate change and the dangers of HAB. Students were able to compare aerial data with their own observations, and also gained experience in aeronautical science through field trips to local airports, hands-on experience with private research aircraft, specialized equipment used for data collection, and advanced ground instruction from research pilots. As a result of reaching out to local educators serving diverse student populations and facilitating collaborative planning, we successfully created new educational opportunities with active partnerships between formal educational institutions and informal citizen science research programs, which broadened access to and engagement in aerospace education and STEM learning experiences in our local community.

China's rise as a major contributor to science and technology.

PubMed

Xie, Yu; Zhang, Chunni; Lai, Qing

2014-07-01

In the past three decades, China has become a major contributor to science and technology. China now employs an increasingly large labor force of scientists and engineers at relatively high earnings and produces more science and engineering degrees than the United States at all levels, particularly bachelor's. China's research and development expenditure has been rising. Research output in China has been sharply increasing since 2002, making China the second largest producer of scientific papers after the United States. The quality of research by Chinese scientists has also been improving steadily. However, China's rise in science also faces serious difficulties, partly attributable to its rigid, top-down administrative system, with allegations of scientific misconduct trending upward.

Precise protein structure determination provides significant information on life science research, although high-quality crystals are not easily obtained. We developed a system for producing high-quality protein crystals with high throughput. Using this system, gravity-controlled crystallization are made possible by a magnetic microgravity environment. In addition, in-situ and real-time observation and time-lapse imaging of crystal growth are feasible for over 200 solution samples independently. In this paper, we also report results of crystallization experiments for two protein samples. Crystals grown in the system exhibited magnetic orientation and showed higher and more homogeneous quality compared with the control crystals. The structural analysis reveals that making use of the magnetic microgravity during the crystallization process helps us to build a well-refined protein structure model, which has no significant structural differences with a control structure. Therefore, the system contributes to improvement in efficiency of structural analysis for "difficult" proteins, such as membrane proteins and supermolecular complexes.

Prestigious Science Journals Struggle to Reach Even Average Reliability

PubMed Central

Brembs, Björn

2018-01-01

In which journal a scientist publishes is considered one of the most crucial factors determining their career. The underlying common assumption is that only the best scientists manage to publish in a highly selective tier of the most prestigious journals. However, data from several lines of evidence suggest that the methodological quality of scientific experiments does not increase with increasing rank of the journal. On the contrary, an accumulating body of evidence suggests the inverse: methodological quality and, consequently, reliability of published research works in several fields may be decreasing with increasing journal rank. The data supporting these conclusions circumvent confounding factors such as increased readership and scrutiny for these journals, focusing instead on quantifiable indicators of methodological soundness in the published literature, relying on, in part, semi-automated data extraction from often thousands of publications at a time. With the accumulating evidence over the last decade grew the realization that the very existence of scholarly journals, due to their inherent hierarchy, constitutes one of the major threats to publicly funded science: hiring, promoting and funding scientists who publish unreliable science eventually erodes public trust in science.

Fostering Earth Science Inquiry From Within a Native Hawaiian Cultural Framework In O`ahu (Hawai`i) Through A Multidisciplinary Place-Based High School Summer Enrichment Program

NASA Astrophysics Data System (ADS)

Moxey, L.; Dias, R.; Legaspi, E.

2010-12-01

During the summer of 2010, twenty-five public high school students from underrepresented communities and ethnicities (Hawaiian, part-Hawaiian, Sāmoan, Filipino, Pacific Islander) in O`ahu (Hawai`i) participated in the Mālama Ke Ahupua`a (protecting our watershed) program. This rigorous three-week hands-on, place-based multidisciplinary program provided students with the opportunity of visiting the Mānoa Valley watershed (O`ahu, Hawaii) for learning and experiencing the Earth Science System dynamics that comprises it, while simultaneously exploring the significance of the ahupua`a (watershed) as related to native Hawaiian history and culture. While earning Hawaii DOE-approved academic credit, students utilized GPS/GIS technology, quantitative water quality testing equipment, and environmental monitoring tools for performing a watershed survey and water quality study of Mānoa Stream (Mānoa Valley) from its inception in the mountains, its advance through Honolulu’s urbanized areas, and its convergence with the Pacific Ocean. Through this hands-on field-based study, students documented changes in the watershed’s environment as reflected in declining water quality induced by anthropogenic pollution sources and urbanization. Students also visited relevant native Hawaiian cultural sites in Mānoa, and explored their direct links with the historical sustainable usage of the watershed’s natural resources, both from a cultural and science-based perspective. Finally, traditional wa`a (native Hawaiian outrigger canoes) were used as both cultural resources for discussing ancient Polynesian exploration, as well as scientific research platforms for conducting near-shore reef surveys & assessments. This program served to promote not only Earth Science literacy and STEM skills, but also contributed to further environmental stewardship while fostering native Hawaiian & Polynesian cultural identities.

This report describes the roles of Good Manufacturing Practices (GMP) in pharmaceutical product quality control. There are three keys to pharmaceutical product quality control. They are specifications, thorough product characterization during development, and adherence to GMP as the ICH Q6A guideline on specifications provides the most important principles in its background section. Impacts of the revised Pharmaceutical Affairs Law (rPAL) which became effective in 2005 on product quality control are discussed. Progress of ICH discussion for Pharmaceutical Development (Q8), Quality Risk Management (Q9) and Pharmaceutical Quality System (Q10) are reviewed. In order to reconstruct GMP guidelines and GMP inspection system in the regulatory agencies under the new paradigm by rPAL and the ICH, a series of Health Science studies were conducted. For GMP guidelines, product GMP guideline, technology transfer guideline, laboratory control guideline and change control system guideline were written. For the GMP inspection system, inspection check list, inspection memo and inspection scenario were proposed also by the Health Science study groups. Because pharmaceutical products and their raw materials are manufactured and distributed internationally, collaborations with other national authorities are highly desired. In order to enhance the international collaborations, consistent establishment of GMP inspection quality system throughout Japan will be essential.

Top Nurse-Management Staffing Collapse and Care Quality in Nursing Homes

PubMed Central

Hunt, Selina R.; Corazzini, Kirsten; Anderson, Ruth A.

2014-01-01

Director of nursing turnover is linked to staff turnover and poor quality of care in nursing homes; however the mechanisms of these relationships are unknown. Using a complexity science framework, we examined how nurse management turnover impacts system capacity to produce high quality care. This study is a longitudinal case analysis of a nursing home (n = 97 staff) with 400% director of nursing turnover during the study time period. Data included 100 interviews, observations and documents collected over 9 months and were analyzed using immersion and content analysis. Turnover events at all staff levels were nonlinear, socially mediated and contributed to dramatic care deficits. Federal mandated, quality assurance mechanisms failed to ensure resident safety. High multilevel turnover should be elevated to a sentinel event for regulators. Suggestions to magnify positive emergence in extreme conditions and to improve quality are provided. PMID:24652943

Incorporating spectroscopy and measurement technology into the high school chemistry laboratory

NASA Astrophysics Data System (ADS)

Harbert, Emily Ann

Science and technology are becoming increasingly important in maintaining a healthy economy at home and a competitive edge on the world stage, though that is just one facet affected by inadequate science education in the United States. Engaging students in the pursuit of knowledge and giving them the skills to think critically are paramount. One small way to assist in achieving these goals is to increase the quality and variety of technology-rich activities conducted in high school classrooms. Incorporating more laboratory measurement technology into high schools may incite more student interest in the processes and practices of science and may allow students to learn to think more critically about their data and what it represents. The first objective of the work described herein was to determine what measurement technology is being used in schools and to what extent, as well as to determine other teacher needs and preferences. Second, the objective was to develop a new program to provide incoming freshmen (or rising seniors) with measurement technology training they did not receive in high school, and expose them to new research and career opportunities in science. The final objective was to create a technology-rich classroom laboratory activity for use in high schools.

Evaluating the state of quality-improvement science through evidence synthesis: insights from the closing the quality gap series.

PubMed

McDonald, Kathryn M; Schultz, Ellen M; Chang, Christine

2013-01-01

The Closing the Quality Gap series from the Agency for Healthcare Research and Quality summarizes evidence for eight high-priority health care topics: outcomes used in disability research, bundled payment programs, public reporting initiatives, health care disparities, palliative care, the patient-centered medical home, prevention of health care-associated infections, and medication adherence. To distill evidence from this series and provide insight into the "state of the science" of quality improvement (QI). We provided common guidance for topic development and qualitatively synthesized evidence from the series topic reports to identify cross-topic themes, challenges, and evidence gaps as related to QI practice and science. Among topics that examined effectiveness of QI interventions, we found improvement in some outcomes but not others. Implementation context and potential harms from QI activities were not widely evaluated or reported, although market factors appeared important for incentive-based QI strategies. Patient-focused and systems-focused strategies were generally more effective than clinician-focused strategies, although the latter approach improved clinician adherence to infection prevention strategies. Audit and feedback appeared better for targeting professionals and organizations, but not patients. Topic reviewers observed heterogeneity in outcomes used for QI evaluations, weaknesses in study design, and incomplete reporting. Synthesizing evidence across topics provided insight into the state of the QI field for practitioners and researchers. To facilitate future evidence synthesis, consensus is needed around a smaller set of outcomes for use in QI evaluations and a framework and lexicon to describe QI interventions more broadly, in alignment with needs of decision makers responsible for improving quality.

2017-12-01

Environmental challenges, from local water quality to the effects of global climate change, are overwhelming the mainstream science community. We need help. Citizen science offers one solution pathway - in the ideal, thousands of participants engaged in authentic science that delivers high quality information not otherwise obtainable. But in the real world, are citizen science data used? And more broadly: what are the interactions between citizen science and natural resource management in service of conserving or protecting system structure and function? The Coastal Observation and Seabird Survey Team (COASST) is a rigoros citizen science program focused on documenting patterns of beached bird and marine debris abundance on beaches along the coast of the Pacific Northwest and Alaska. Housed at the University of Washington, COASST partners directly with a wide range of local, tribal, state and federal agencies to effect positive change and a wide range of scientific, community and educational outcomes. Following from years of trial, error and adaptive management, we propose a "trust pathway" between citizen science and agencies that moves from an initial contact and multiple interaction types to eventual partnership and capacity sharing. Along the way are trust catalysts, including but not limited to: stakeholder engagement, data QA/QC, interactive data analysis, housing at an academic institution, and timely, repeated communication. In this presentation, we will discuss strategies and outcomes employed by COASST for fostering trust and successful partnerships, drawing on 20 years of program experience as well as reflections from a variety of partners and stakholdres.

Participation in inquiry-based science education, which focuses on student-constructed learning, has been linked to academic success. Whereas the benefits of this type of science education are evident, access to such high-quality science curriculum and programming is not equitable. Black and Latino students in particular have less access to supplementary science programming, and fewer opportunities to engage in inquiry-based education. This paper describes outcomes associated with an inquiry-based out-of-school time science education program, Nuestro Futuro: Applied Science Education to Engage Black and Latino Youth (NFASE), which sought to build the capacity of middle school students of color to 'think' like health scientists from diverse disciplinary perspectives. The program was designed with the intent of (1) improving student attitudes toward and motivation for science and (2) increasing active and engaged citizenship (AEC). NFASE students explored health inequity and the social determinants of health locally and engaged in developing health promotion, outreach and education efforts targeted to their peers, parents/families, and community. Interest in the program was high overall, but implementation was not without challenges. Although evaluation outcomes indicate that there were no statistically significant changes in science-related attitudes or motivation, students reported significant increases in neighborhood social connection, as well as overall AEC.

2009-01-01

For almost 10 years, standard global products from NASA's Earth Observing System s (EOS) two Moderate Resolution Imaging Spectroradiometer (MODIS) sensors are being used world-wide for earth science research and applications. This paper discusses the lessons learned in developing the science algorithms and the data systems needed to produce these high quality data products for the earth sciences community. Strong science team leadership and communication, an evolvable and scalable data system, and central coordination of QA and validation activities enabled the data system to grow by two orders of magnitude from the initial at-launch system to the current system able to reprocess data from both the Terra and Aqua missions in less than a year. Many of the lessons learned from MODIS are already being applied to follow-on missions.

Observations from the Pre-Aerosol Cloud and ocean Ecosystem (PACE) and Hyperspectral InfraRed Imager (HyspIRI) satellite missions are highly complementary and have the potential to significantly advance understanding of various science and applications challenges in the ocean sciences and water quality communities. Scheduled for launch in the 2022 timeframe, PACE is designed to make climate-quality global measurements essential for understanding ocean biology, biogeochemistry and ecology, and determining the role of the ocean in global biogeochemical cycling and ocean ecology, and how it affects and is affected by climate change. PACE will provide high signal-to-noise, hyperspectral observations over an extended spectral range (UV to SWIR) and will have global coverage every 1-2 days, at approximately 1 km spatial resolution; furthermore, PACE is currently designed to include a polarimeter, which will vastly improve atmospheric correction algorithms over water bodies. The PACE mission will enable advances in applications across a range of areas, including oceans, climate, water resources, ecological forecasting, disasters, human health and air quality. HyspIRI, with contiguous measurements in VSWIR, and multispectral measurements in TIR, will be able to provide detailed spectral observations and higher spatial resolution (30 to 60-m) over aquatic systems, but at a temporal resolution that is approximately 5-16 days. HyspIRI would enable improved, detailed studies of aquatic ecosystems, including benthic communities, algal blooms, coral reefs, and wetland species distribution as well as studies of water quality indicators or pollutants such as oil spills, suspended sediment, and colored dissolved organic matter. Together, PACE and HyspIRI will be able to address numerous applications and science priorities, including improving and extending climate data records, and studies of inland, coastal and ocean environments.

What Do Informal Educators Need To Be Successful In Teaching Planetary Science And Engineering?: Results From The PLANETS Out-Of-School Time Educator Needs Assessment (NASA NNX16AC53A)

NASA Astrophysics Data System (ADS)

Clark, J.; Bloom, N.

2016-12-01

Planetary Learning that Advances the Nexus of Engineering, Technology, and Science (PLANETS) is five-year interdisciplinary and cross-institutional partnership to develop and disseminate out-of-school time curricular and professional development modules that integrate planetary science, technology, and engineering. The Center for Science Teaching and Learning (CSTL) at Northern Arizona University (NAU), the U.S. Geological Survey (USGS) Astrogeology Science Center (Astrogeology), and the Museum of Science (MOS) Boston are partners in developing, piloting, and researching the impact of three out of school time planetary science and engineering curriculum and related professional development units over the life of the project. Critical to the success of out-of-school time curriculum implementation is to consider the needs of the informal education leaders. The CSTL at NAU is conducting a needs-assessment of OST educators nationwide to identify the gaps between current knowledge and abilities of OST educators and the knowledge and abilities necessary in order to facilitate effective STEM educational experiences for youth. The research questions are: a. What are current conditions of OST programs and professional development for OST educators? b. What do OST educators and program coordinators already know and think about facilitating meaningful and high quality STEM instruction? c. What are perceived needs of OST educators and program coordinators in order to implement meaningful and high quality STEM instruction? d. What design decisions will make professional development experiences more accessible, acceptable and useful to OST educators and program coordinators? In this presentation we will share the preliminary results of the national survey. The information about the needs of informal STEM educators can inform other NASA Science Mission Directorate educational partners in their program development in addition to AGU members designing informal education outreach.

Perceptions versus Realities: Exploring Needs and Science Learning Outcomes In the Mississippi Delta

NASA Astrophysics Data System (ADS)

Fitts, Lacey S.

The Mississippi Delta (MS Delta) is a high-poverty region in northwestern Mississippi located between the Mississippi and Yazoo rivers. The Delta is home to sixteen rural counties with over seventy failing or underperforming schools. Many of these schools lack the resources necessary to ensure adequate opportunities for all students. Learning outcomes for the state are among the lowest in the nation, and scores in the rural Delta are far below the state average. Graduating seniors take the ACT college entrance exam, with about 10% of Mississippi seniors scoring as "college-ready" in science. The region has a critical shortage of science teachers, and many schools do not offer advanced science courses. This study assessed teachers' needs, identified key characteristics of the secondary science programs in which they teach, and sought to understand conditions affecting science learning outcomes. An inventory of science teachers' needs was administered to teachers in the region. The greatest needs were material resources, high quality training, and strategies for improving poor reading and problem-solving skills of students. Of the factors examined, the percentage of students receiving free lunch had the strongest correlation with science learning outcomes in the school, higher than access to resources, number of science courses offered, and level of self-reported teacher need. A three-tiered approach to improving science learning outcomes has been developed, emphasizing community relationships, targeted professional development, and relevant science curriculum.

Negotiating the terrain of high-stakes accountability in science teaching

NASA Astrophysics Data System (ADS)

Aronson, Isaak

Teachers interact with their students on behalf of the entire educational system. The aim of this study is to explore how biology teachers understand and construct their practice in a high-stakes accountability environment that is likely to be riddled with tensions. By critically questioning the technical paradigms of accountability this study challenges the fundamental assumptions of accountability. Such a critical approach may help teachers develop empowerment strategies that can free them from the de-skilling effects of the educational accountability system. This interpretive case study of a high-school in Maryland is grounded in three streams of research literature: quality science instruction based on scientific inquiry, the effects of educational accountability on the curriculum, and the influence of policy on classroom practice with a specific focus on how teachers balance competing tensions. This study theoretically occurs at the intersection of educational accountability and pedagogy. In terms of data collection, I conduct two interviews with all six biology teachers in the school. I observe each teacher for at least fifteen class periods. I review high-stakes accountability policy documents from the federal, state, and district levels of the education system. Three themes emerge from the research. The first theme, "re-defining science teaching," captures how deeply accountability structures have penetrated the science curriculum. The second theme, "the pressure mounts," explores how high-stakes accountability in science has increased the stress placed on teachers. The third theme, "teaching-in-between," explores how teachers compromise between accountability mandates and their own understandings of quality teaching. Together, the three themes shed light on the current high-stakes climate in which teachers currently work. This study's findings inform the myriad paradoxes at all levels of the educational system. As Congress and advocacy groups battle over the reauthorization of No Child Left Behind, they may not pay adequate attention to all the inconsistencies. Educators and researchers must take a critical look at accountability policies. Accountability should promote optimism, responsibility, job satisfaction, avenues for developing pedagogical expertise, and collaboration between teachers and administrators. Only then is it likely to improve educational opportunities for all students.

Preservice Elementary Teachers' Science Self-Efficacy Beliefs and Science Content Knowledge

NASA Astrophysics Data System (ADS)

Menon, Deepika; Sadler, Troy D.

2016-10-01

Self-efficacy beliefs that relate to teachers' motivation and performance have been an important area of concern for preservice teacher education. Research suggests high-quality science coursework has the potential to shape preservice teachers' science self-efficacy beliefs. However, there are few studies examining the relationship between science self-efficacy beliefs and science content knowledge. The purpose of this mixed methods study is to investigate changes in preservice teachers' science self-efficacy beliefs and science content knowledge and the relationship between the two variables as they co-evolve in a specialized science content course. Results from pre- and post-course administrations of the Science Teaching Efficacy Belief Instrument-B (Bleicher, 2004) and a physical science concept test along with semi-structured interviews, classroom observations and artifacts served as data sources for the study. The 18 participants belonged to three groups representing low, medium and high initial levels of self-efficacy beliefs. A repeated measures multivariate analysis of variance design was used to test the significance of differences between the pre- and post-surveys across time. Results indicated statistically significant gains in participants' science self-efficacy beliefs and science conceptual understandings. Additionally, a positive moderate relationship between gains in science conceptual understandings and gains in personal science teaching efficacy beliefs was found. Qualitative analysis of the participants' responses indicated positive shifts in their science teacher self-image and they credited their experiences in the course as sources of new levels of confidence to teach science. The study includes implications for preservice teacher education programs, science teacher education, and research.

The Radioisotope Power Systems Program of the Idaho National Laboratory makes an empirical case for a highly integrated Quality Assurance function pertaining to the preparation, assembly, testing, storage and transportation of 238Pu fueled radioisotope thermoelectric generators. Case data represents multiple campaigns including the Pluto/New Horizons mission,more » the Mars Science Laboratory mission in progress, and other related projects. Traditional Quality Assurance models would attempt to reduce cost by minimizing the role of dedicated Quality Assurance personnel in favor of either functional tasking or peer-based implementations. Highly integrated Quality Assurance adds value by placing trained quality inspectors on the production floor side-by-side with nuclear facility operators to enhance team dynamics, reduce inspection wait time, and provide for immediate, independent feedback. Value is also added by maintaining dedicated Quality Engineers to provide for rapid identification and resolution of corrective action, enhanced and expedited supply chain interfaces, improved bonded storage capabilities, and technical resources for requirements management including data package development and Certificates of Inspection. A broad examination of cost-benefit indicates highly integrated Quality Assurance can reduce cost through the mitigation of risk and reducing administrative burden thereby allowing engineers to be engineers, nuclear operators to be nuclear operators, and the cross-functional team to operate more efficiently. Applicability of this case extends to any high-value, long-term project where traceability and accountability are determining factors.« less

High School Science Teachers' Perceptions of Teaching Content-Related Reading Comprehension Instruction

NASA Astrophysics Data System (ADS)

Williams, Theresa

In order to achieve academic success, students must be able to comprehend written material in content-area textbooks. However, a large number of high school students struggle to comprehend science content. Research findings have demonstrated that students make measurable gains in comprehending content-area textbooks when provided quality reading comprehension instruction. The purpose of this study was to gain an understanding of how high school science teachers perceived their responsibility to provide content-related comprehension instruction and 10 high school science teachers were interviewed for this study. Data analysis consisted of open, axial, and selective coding. The findings revealed that 8 out of the 10 participants believed that it is their responsibility to provide reading comprehension. However, the findings also revealed that the participants provided varying levels of reading comprehension instruction as an integral part of their science instruction. The potential for positive social change could be achieved by teachers and administrators. Teachers may use the findings to reflect upon their own personal feelings and beliefs about providing explicit reading comprehension. In addition to teachers' commitment to reading comprehension instruction, administrators could deliberate about professional development opportunities that might improve necessary skills, eventually leading to better comprehension skills for students and success in their education.

Glomerular disease: why is there a dearth of high quality clinical trials?

PubMed

Leaf, David E; Appel, Gerald B; Radhakrishnan, Jai

2010-08-01

There is a paucity of high quality clinical trials in glomerular disease, particularly in non-diabetic kidney disease. The aims of this review include quantifying the extent of this problem and exploring reasons for the scarcity of such trials in primary glomerular disease, with an emphasis on immunoglobulin A nephropathy, minimal change disease, focal segmental glomerulosclerosis, and membranous nephropathy in comparison with the more common diseases of diabetic nephropathy and lupus nephritis. Reasons for the dearth of high quality clinical trials in primary glomerular disease include (1) low prevalence of disease; (2) variability in clinical presentation; (3) variability in treatment response; (4) lack of consensus in definitions; (5) difficulty in recruiting patients; (6) high costs of randomized controlled trials; and (7) lack of collaborative efforts. To facilitate greater numbers of high quality clinical trials in glomerular disease, practice guidelines should establish common classification systems of disease and common clinical end points, industry and non-industry sponsored research should find common ground and work together toward advancing science, and national registries should be created to encourage collaborations across institutions and across nations.

A 100-Year Review: The production of fluid (market) milk.

PubMed

Barbano, David M

2017-12-01

During the first 100 years of the Journal of Dairy Science, dairy foods and dairy production dairy scientists have partnered to publish new data and research results that have fostered the development of new knowledge. This knowledge has been the underpinning of both the commercial development of the fluid milk processing industry and regulations and marketing policies for the benefit of dairy farmers, processors, and consumers. During the first 50 years, most of the focus was on producing and delivering high-quality raw milk to factories and improving the shelf life of pasteurized fluid milk. During the second 50 years, raw milk quality was further improved through the use of milk quality payment incentives. Due to changing demographics and lifestyle, whole fluid milk consumption declined and processing technologies were developed to increase the range of fluid milk products (skim and low-fat milks, flavored milks, lactose-reduced milk, long-shelf-life milks, and milks with higher protein and calcium contents) offered to the consumer. In addition, technology to produce specialty high-protein sports beverages was developed, which expanded the milk-based beverage offerings to the consumer.

21st Century Learning Skills Embedded in Climate Literacy Teacher Professional Development

NASA Astrophysics Data System (ADS)

Myers, R. J.; Schwerin, T. G.; Blaney, L.

2011-12-01

Trilling and Fadel's "21st Century Learning Skills" defines a vision of how to infuse an expanded set of skills, competencies and flexibilities into the classroom. Among these skills are global awareness, health and environmental literacy. The authors contend that in order for our students to compete, they will need critical thinking and problem solving skills, communication and collaboration, and creativity and innovation. Students will also need to be digital savvy. This poster outlines a program of preparing teachers to implement inquiry-based modules that allow students to exercise hypothetical deductive reasoning to address climate literacy issues such as: the Dust Bowl, thermohaline circulation, droughts, the North Atlantic Oscillation, climate variability and energy challenges. This program is implemented through the Earth System Science Education Alliance. ESSEA supports the educational goal of "attracting and retaining students in science careers" and the associated goal of "attracting and retaining students in science through a progression of educational opportunities for students, teachers and faculty." ESSEA provides long-duration educator professional development that results in deeper content understanding and confidence in teaching global climate change and science disciplines. The target audience for this effort is pre-service and in-service K-12 teachers. The ESSEA program develops shared educational resources - including modules and courses - that are based on NASA and NOAA climate science and data. The program is disseminated through the ESSEA Web site: http://essea.courses.strategies.org. ESSEA increases teachers' access to high-quality materials, standards-based instructional methods and content knowledge. Started in 2000 and based on online courses for K-12 teachers, ESSEA includes the participation of faculty at 45 universities and science centers. Over 3,500 pre- and in-service K-12 teachers have completed ESSEA courses. In addition to 21st Century learning skills, the ESSEA program is based on the urgent need for professional development for pre- and in-service teachers of Earth science. The Revolution in Earth and Space Science Education (2001) cites the Glenn Report saying "...the way to interest children in mathematics and science is through teachers who are not only enthusiastic about their subjects, but who are also steeped in their disciplines and who have the professional training - as teachers - to teach those subjects well. Nor is this teacher training simply a matter of preparation; it depends just as much - or even more - on sustained, high-quality professional development" (p. 1). This treatise states that Earth and space sciences are in the greatest need for professional development. Teachers find themselves inadequately qualified to teach science and find that professional development is not available or lacking in quality. The ESSEA program addresses its educational priorities through enriching pre- and in-service Earth science teachers' backgrounds in Earth system science, specifically in the area of global climate change, and through developing educational materials in support of science education.

Tactical Approaches for Trading Science Objectives Against Measurements and Mission Design: Science Traceability Techniques at the Jet Propulsion Laboratory

Nash, A. E., III

2017-12-01

The most common approaches to identifying the most effective mission design to maximize science return from a potential set of competing alternative design approaches are often inefficient and inaccurate. Recently, Team-X at the Jet Propulsion Laboratory undertook an effort to improve both the speed and quality of science - measurement - mission design trade studies. We will report on the methodology & processes employed and their effectiveness in trade study speed and quality. Our results indicate that facilitated subject matter expert peers are the keys to speed and quality improvements in the effectiveness of science - measurement - mission design trade studies.

Digital Terrain Model (DTM) creation is essential to improving our understanding of the formation processes of the Martian surface. Although there have been previous demonstrations of open-source or commercial planetary 3D reconstruction software, planetary scientists are still struggling with creating good quality DTMs that meet their science needs, especially when there is a requirement to produce a large number of high quality DTMs using "free" software. In this paper, we describe a new open source system to overcome many of these obstacles by demonstrating results in the context of issues found from experience with several planetary DTM pipelines. We introduce a new fully automated multi-resolution DTM processing chain for NASA Mars Reconnaissance Orbiter (MRO) Context Camera (CTX) and High Resolution Imaging Science Experiment (HiRISE) stereo processing, called the Co-registration Ames Stereo Pipeline (ASP) Gotcha Optimised (CASP-GO), based on the open source NASA ASP. CASP-GO employs tie-point based multi-resolution image co-registration, and Gotcha sub-pixel refinement and densification. CASP-GO pipeline is used to produce planet-wide CTX and HiRISE DTMs that guarantee global geo-referencing compliance with respect to High Resolution Stereo Colour imaging (HRSC), and thence to the Mars Orbiter Laser Altimeter (MOLA); providing refined stereo matching completeness and accuracy. All software and good quality products introduced in this paper are being made open-source to the planetary science community through collaboration with NASA Ames, United States Geological Survey (USGS) and the Jet Propulsion Laboratory (JPL), Advanced Multi-Mission Operations System (AMMOS) Planetary Data System (PDS) Pipeline Service (APPS-PDS4), as well as browseable and visualisable through the iMars web based Geographic Information System (webGIS) system.

Calculating the quality of public high-throughput sequencing data to obtain a suitable subset for reanalysis from the Sequence Read Archive

Nakazato, Takeru; Bono, Hidemasa

2017-01-01

Abstract It is important for public data repositories to promote the reuse of archived data. In the growing field of omics science, however, the increasing number of submissions of high-throughput sequencing (HTSeq) data to public repositories prevents users from choosing a suitable data set from among the large number of search results. Repository users need to be able to set a threshold to reduce the number of results to obtain a suitable subset of high-quality data for reanalysis. We calculated the quality of sequencing data archived in a public data repository, the Sequence Read Archive (SRA), by using the quality control software FastQC. We obtained quality values for 1 171 313 experiments, which can be used to evaluate the suitability of data for reuse. We also visualized the data distribution in SRA by integrating the quality information and metadata of experiments and samples. We provide quality information of all of the archived sequencing data, which enable users to obtain sufficient quality sequencing data for reanalyses. The calculated quality data are available to the public in various formats. Our data also provide an example of enhancing the reuse of public data by adding metadata to published research data by a third party. PMID:28449062

Can health insurance improve access to quality care for the Indian poor?

PubMed

Michielsen, Joris; Criel, Bart; Devadasan, Narayanan; Soors, Werner; Wouters, Edwin; Meulemans, Herman

2011-08-01

Recently, the Indian government launched health insurance schemes for the poor both to protect them from high health spending and to improve access to high-quality health services. This article aims to review the potentials of health insurance interventions in order to improve access to quality care in India based on experiences of community health insurance schemes. PubMed, Ovid MEDLINE (R), All EBM Reviews, CSA Sociological Abstracts, CSA Social Service Abstracts, EconLit, Science Direct, the ISI Web of Knowledge, Social Science Research Network and databases of research centers were searched up to September 2010. An Internet search was executed. One thousand hundred and thirty-three papers were assessed for inclusion and exclusion criteria. Twenty-five papers were selected providing information on eight schemes. A realist review was performed using Hirschman's exit-voice theory: mechanisms to improve exit strategies (financial assets and infrastructure) and strengthen patient's long voice route (quality management) and short voice route (patient pressure). All schemes use a mix of measures to improve exit strategies and the long voice route. Most mechanisms are not effective in reality. Schemes that focus on the patients' bargaining position at the patient-provider interface seem to improve access to quality care. Top-down health insurance interventions with focus on exit strategies will not work out fully in the Indian context. Government must actively facilitate the potential of CHI schemes to emancipate the target group so that they may transform from mere passive beneficiaries into active participants in their health.

2013-01-01

The U.S. Geological Survey (USGS) Land Remote Sensing Program is developing an operational capability to produce Climate Data Records (CDRs) and Essential Climate Variables (ECVs) from the Landsat Archive to support a wide variety of science and resource management activities from regional to global scale. The USGS Earth Resources Observation and Science (EROS) Center is charged with prototyping systems and software to generate these high-level data products. Various USGS Geographic Science Centers are charged with particular ECV algorithm development and (or) selection as well as the evaluation and application demonstration of various USGS CDRs and ECVs. Because it is a foundation for many other ECVs, the first CDR in development is the Landsat Surface Reflectance Product (LSRP). The LSRP incorporates data quality information in a bit-packed structure that is not readily accessible without postprocessing services performed by the user. This document describes two general methods of LSRP quality-data extraction for use in image processing systems. Helpful hints for the installation and use of software originally developed for manipulation of Hierarchical Data Format (HDF) produced through the National Aeronautics and Space Administration (NASA) Earth Observing System are first provided for users who wish to extract quality data into separate HDF files. Next, steps follow to incorporate these extracted data into an image processing system. Finally, an alternative example is illustrated in which the data are extracted within a particular image processing system.

Urban Water and Riverine Quality: Participatory Science in Singapore

NASA Astrophysics Data System (ADS)

Higgitt, D. L.

2011-12-01

Singapore is a highly urbanised environment experiencing tropical monsoon hydrological regimes. A heavily engineered fluvial system has been developed over time to provide efficient drainage and reduce the area subject to flood risk. However, recent interest in ecosystem-based approaches to river management and the enhancement of the aesthetic and ecological 'quality' of riverine landscape, coupled with concerns about climate change, has challenged the prevailing engineering view. This is reflected in the Public Utility Board (PUB) ABC Waters Programme, which also seeks to develop community interest in riverine environments and engagement with water-related concerns. As part of a programme developing participatory GIS (PGIS) with school and university students, we have undertaken applications involving participant observation, reporting and analysis of water quality data and habitat quality based on a simplified version of the UK Environment Agency's River Habitat Survey. From an educational perspective, there is evidence that these PGIS initiatives raise environmental awareness and enhance geospatial thinking, particularly in relation to catchment management concepts. The extent to which participant-derived data can contribute to a citizen science of urban water quality and hence deliver some aspects of the community engagement sought after by the authorities, is a topic of debate.

The Relationship of Previous Training and Experience of Journal Peer Reviewers to Subsequent Review Quality

PubMed Central

Callaham, Michael L; Tercier, John

2007-01-01

Background Peer review is considered crucial to the selection and publication of quality science, but very little is known about the previous experiences and training that might identify high-quality peer reviewers. The reviewer selection processes of most journals, and thus the qualifications of their reviewers, are ill defined. More objective selection of peer reviewers might improve the journal peer review process and thus the quality of published science. Methods and Findings 306 experienced reviewers (71% of all those associated with a specialty journal) completed a survey of past training and experiences postulated to improve peer review skills. Reviewers performed 2,856 reviews of 1,484 separate manuscripts during a four-year study period, all prospectively rated on a standardized quality scale by editors. Multivariable analysis revealed that most variables, including academic rank, formal training in critical appraisal or statistics, or status as principal investigator of a grant, failed to predict performance of higher-quality reviews. The only significant predictors of quality were working in a university-operated hospital versus other teaching environment and relative youth (under ten years of experience after finishing training). Being on an editorial board and doing formal grant (study section) review were each predictors for only one of our two comparisons. However, the predictive power of all variables was weak. Conclusions Our study confirms that there are no easily identifiable types of formal training or experience that predict reviewer performance. Skill in scientific peer review may be as ill defined and hard to impart as is “common sense.” Without a better understanding of those skills, it seems unlikely journals and editors will be successful in systematically improving their selection of reviewers. This inability to predict performance makes it imperative that all but the smallest journals implement routine review ratings systems to routinely monitor the quality of their reviews (and thus the quality of the science they publish).

Rockwell, A.; Clark, R. D.; Stevermer, A.

2016-12-01

The study of observational science crosses all other subject areas and requires a new innovative paradigm: a collaboration of experts to create high quality, content-rich learning modules that will elevate the scientific literacy and technical competency of undergraduate and graduate students. This collaborative project will design, develop, and openly distribute a series of interactive, multimedia, online modules that can be effectively integrated into meteorology courses on instrumentation, measurement science, and observing systems to supplement traditional pedagogies and enhance blended instruction. The modules will address topics such as principles of instrumentation and measurement to the theory and practice of measuring a host of meteorological variables. The impact will have a profound effect on the atmospheric observational sciences community by fulfilling a need for contemporary, interactive, multimedia guided education and training modules integrating the latest instructional design and assessment tools in observational science. Thousands of undergraduate and graduate students will benefit, while course instructors will value a set of high quality modules to use as supplements to their courses. The modules can serve as an alternative to observational research training and fill the void between field projects or assist those schools that lack the resources to stage a field- or laboratory-based instrumentation experience. This project brings together the intellectual capital of the scientists and engineers of National Center for Atmospheric Research Earth Observing Laboratory as subject matter experts, the artistic talents and instructional design acumen of the COMET program, and the project leadership, vision, teaching expertise in instruments and observational science at Millersville University.

High School Science Teachers' Receptivity to the Next Generation Science Standards: An Examination of Discipline Specific Factors

NASA Astrophysics Data System (ADS)

Shapiro, Lesley Jacqueline

The Next Generation Science Standards (NGSS), are the biggest change to American science education since the National Science Education Standards (NSES) were published. While inquiry was central to the NSES, science assessment largely addressed factual knowledge acquisition. The NGSS represent a significant practical change for teachers as they mark a return to the ideals specified in the National Science Education Standards (NSES) and Benchmarks for Science Literacy. The purpose of this explanatory sequential, mixed-methods study was to identify and compare the factors that influenced high school science teachers' receptivity to the curricular shifts necessitated by the adoption of the NGSS. The survey data identified three factors as significant predictors of teacher receptivity: teachers' non-monetary cost-benefit analysis, alignment between the NGSS and their current teaching style, and concerns about student readiness. To understand how these factors operate in the classroom, both receptive and non-receptive teachers were interviewed. In terms of cost-benefit analysis, all teachers agree that time is a significant cost. This includes the time it takes to adapt lessons to the NGSS, and the time it takes to teach in a way that integrates the three parts of the NGSS which are the practices of science and engineering, the crosscutting concepts, and the disciplinary core ideas. In terms of alignment between their teaching style and the NGSS, teachers talked about the lack of examples of what NGSS-aligned instruction looks like and the dearth of accessible high quality professional development. Finally, concerns about students' readiness focused on both inadequate preparation for college-level science coursework and deficits in science instruction in the lower grades.

RUSHMAPS: Real-Time Uploadable Spherical Harmonic Moment Analysis for Particle Spectrometers

NASA Technical Reports Server (NTRS)

Figueroa-Vinas, Adolfo

2013-01-01

RUSHMAPS is a new onboard data reduction scheme that gives real-time access to key science parameters (e.g. moments) of a class of heliophysics science and/or solar system exploration investigation that includes plasma particle spectrometers (PPS), but requires moments reporting (density, bulk-velocity, temperature, pressure, etc.) of higher-level quality, and tolerates a lowpass (variable quality) spectral representation of the corresponding particle velocity distributions, such that telemetry use is minimized. The proposed methodology trades access to the full-resolution velocity distribution data, saving on telemetry, for real-time access to both the moments and an adjustable-quality (increasing quality increases volume) spectral representation of distribution functions. Traditional onboard data storage and downlink bandwidth constraints severely limit PPS system functionality and drive cost, which, as a consequence, drives a limited data collection and lower angular energy and time resolution. This prototypical system exploit, using high-performance processing technology at GSFC (Goddard Space Flight Center), uses a SpaceCube and/or Maestro-type platform for processing. These processing platforms are currently being used on the International Space Station as a technology demonstration, and work is currently ongoing in a new onboard computation system for the Earth Science missions, but they have never been implemented in heliospheric science or solar system exploration missions. Preliminary analysis confirms that the targeted processor platforms possess the processing resources required for realtime application of these algorithms to the spectrometer data. SpaceCube platforms demonstrate that the target architecture possesses the sort of compact, low-mass/power, radiation-tolerant characteristics needed for flight. These high-performing hybrid systems embed unprecedented amounts of onboard processing power in the CPU (central processing unit), FPGAs (field programmable gate arrays), and DSP (digital signal processing) elements. The fundamental computational algorithm de constructs 3D velocity distributions in terms of spherical harmonic spectral coefficients (which are analogous to a Fourier sine-cosine decomposition), but uses instead spherical harmonics Legendre polynomial orthogonal functions as a basis for the expansion, portraying each 2D angular distribution at every energy or, geometrically, spherical speed-shell swept by the particle spectrometer. Optionally, these spherical harmonic spectral coefficients may be telemetered to the ground. These will provide a smoothed description of the velocity distribution function whose quality will depend on the number of coefficients determined. Successfully implemented on the GSFC-developed processor, the capability to integrate the proposed methodology with both heritage and anticipated future plasma particle spectrometer designs is demonstrated (with sufficiently detailed design analysis to advance TRL) to show specific science relevancy with future HSD (Heliophysics Science Division) solar-interplanetary, planetary missions, sounding rockets and/or CubeSat missions.

2009-05-26

The macromolecular crystallography experiment lends itself perfectly to high-throughput technologies. The initial steps including the expression, purification, and crystallization of protein crystals, along with some of the later steps involving data processing and structure determination have all been automated to the point where some of the last remaining bottlenecks in the process have been crystal mounting, crystal screening, and data collection. At the Stanford Synchrotron Radiation Laboratory, a National User Facility that provides extremely brilliant X-ray photon beams for use in materials science, environmental science, and structural biology research, the incorporation of advanced robotics has enabled crystals to be screenedmore » in a true high-throughput fashion, thus dramatically accelerating the final steps. Up to 288 frozen crystals can be mounted by the beamline robot (the Stanford Auto-Mounting System) and screened for diffraction quality in a matter of hours without intervention. The best quality crystals can then be remounted for the collection of complete X-ray diffraction data sets. Furthermore, the entire screening and data collection experiment can be controlled from the experimenter's home laboratory by means of advanced software tools that enable network-based control of the highly automated beamlines.« less

INSPIRE, Initiating New Science Partnerships in Rural Education, is a partnership between Mississippi State University and three school districts in Mississippi's Golden Triangle (Starkville, Columbus, West Point). This program recruits ten graduate fellows each year from geosciences, physics, astronomy, and engineering and pairs them with a participating middle school or high school teacher. The graduate fellows provide technology-supported inquiry-based learning in the earth and space sciences by incorporating their research into classroom instruction and using multiple resources such as Google Earth, geographic information systems (GIS), Celestia, and others. In addition to strengthening the communication skills of the graduate fellows, INSPIRE will increase the content knowledge of participating teachers, provide high-quality instruction using multiple technologies, promote higher education to area high-school students, and provide fellows and teachers with international research experience through our partners in Australia, The Bahamas, England, and Poland. INSPIRE is funded by the Graduate STEM Fellows in K-12 Education Program (GK-12; Award No. DGE-0947419), which is part of the Division for Graduate Education of the National Science Foundation.

Attitude measurement: Judging the emotional intensity of likert-type science attitude statements

NASA Astrophysics Data System (ADS)

Shrigley, Robert L.; Koballa, Thomas R., Jr.

Emotional intensity, that readiness of a teacher to respond favorably or unfavorably toward such psychological objects as science or the teaching of science, is the quality that distinguishes the attitude concept from other related psychological concepts. It would seem, then, that valid attitude statements, if they are to reflect the definition of attitude, would evoke emotional intensity, responses in both a favorable and unfavorable direction by a group of teachers on each item on a science attitude scale. Science educators who design or modify science attitude scales should continue using item-total correlations and other quantitative techniques to test for emotional intensity, but qualitative judgments are necessary, too. In addition, the frequency distribution of data generated by each statement should be examined for skewness and high percentages of neutral responses, both of which can impair the emotional intensity of an item.

Access to consistent, high-quality metadata is critical to finding, understanding, and reusing scientific data. However, while there are many relevant vocabularies for the annotation of a dataset, none sufficiently captures all the necessary metadata. This prevents uniform indexing and querying of dataset repositories. Towards providing a practical guide for producing a high quality description of biomedical datasets, the W3C Semantic Web for Health Care and the Life Sciences Interest Group (HCLSIG) identified Resource Description Framework (RDF) vocabularies that could be used to specify common metadata elements and their value sets. The resulting guideline covers elements of description, identification, attribution, versioning, provenance, and content summarization. This guideline reuses existing vocabularies, and is intended to meet key functional requirements including indexing, discovery, exchange, query, and retrieval of datasets, thereby enabling the publication of FAIR data. The resulting metadata profile is generic and could be used by other domains with an interest in providing machine readable descriptions of versioned datasets. PMID:27602295

New scientific understanding is catalyzed by novel technologies that enhance measurement precision, resolution or type, and that provide new tools to test and develop theory. Over the last 50 years, technology has transformed the hydrologic sciences by enabling direct measurements of watershed fluxes (evapotranspiration, streamflow) at time scales and spatial extents aligned with variation in physical drivers. High frequency water quality measurements, increasingly obtained by in situ water quality sensors, are extending that transformation. Widely available sensors for some physical (temperature) and chemical (conductivity, dissolved oxygen) attributes have become integral to aquatic science, and emerging sensors for nutrients, dissolved CO 2 , turbidity, algal pigments, and dissolved organic matter are now enabling observations of watersheds and streams at time scales commensurate with their fundamental hydrological, energetic, elemental, and biological drivers. Here we synthesize insights from emerging technologies across a suite of applications, and envision future advances, enabled by sensors, in our ability to understand, predict, and restore watershed and stream systems.

Developing and Transitioning Numerical Air Quality Models to Improve Air Quality and Public Health Decision-Making in El Salvador and Costa Rica As Part of the Servir Applied Sciences Team

Thomas, A.; Huff, A. K.; Gomori, S. G.; Sadoff, N.

2014-12-01

In order to enhance the capacity for air quality modeling and improve air quality monitoring and management in the SERVIR Mesoamerica region, members of SERVIR's Applied Sciences Team (AST) are developing national numerical air quality models for El Salvador and Costa Rica. We are working with stakeholders from the El Salvador Ministry of the Environment and Natural Resources (MARN); National University of Costa Rica (UNA); the Costa Rica Ministry of the Environment, Energy, and Telecommunications (MINAET); and Costa Rica National Meteorological Institute (IMN), who are leaders in air quality monitoring and management in the Mesoamerica region. Focusing initially on these institutions will build sustainability in regional modeling activities by developing air quality modeling capability that can be shared with other countries in Mesoamerica. The air quality models are based on the Community Multi-scale Air Quality (CMAQ) model and incorporate meteorological inputs from the Weather Research and Forecasting (WRF) model, as well as national emissions inventories from El Salvador and Costa Rica. The models are being optimized for urban air quality, which is a priority of decision-makers in Mesoamerica. Once experimental versions of the modeling systems are complete, they will be transitioned to servers run by stakeholders in El Salvador and Costa Rica. The numerical air quality models will provide decision support for stakeholders to identify 1) high-priority areas for expanding national ambient air monitoring networks, 2) needed revisions to national air quality regulations, and 3) gaps in national emissions inventories. This project illustrates SERVIR's goal of the transition of science to support decision-making through capacity building in Mesoamerica, and it aligns with the Group on Earth Observations' health societal benefit theme. This presentation will describe technical aspects of the development of the models and outline key steps in our successful collaboration with the Mesoamerican stakeholders, including the processes of identifying and engaging decision-makers, understanding their requirements and limitations, communicating status updates on a regular basis, and providing sufficient training for end users to be able to utilize the models in a decision-making context.

In a systematic effort to improve the preparation of future science teachers, scholars coordinated by the CAPER Center for Astronomy & Physics Education Research are providing a series of high-quality, 2-day professional development workshops, with year-round follow-up support, for college and university professors who prepare future science teachers to work with highly diverse student populations. These workshops focus on reforming and revitalizing undergraduate science teaching methods courses and Earth and Space science content courses that future teachers most often take to reflect contemporary pedagogies and data-rich problem-based learning approaches steeped in authentic scientific inquiry, which consistently demonstrate effectiveness with diverse students. Participants themselves conduct science data-rich research projects during the institutes using highly regarded approaches to inquiry using proven models. In addition, the Institute allocates significant time to illustrating best practices for working with diverse students. Moreover, participants leave with a well-formulated action plan to reform their courses targeting future teachers to include more data-rich scientific inquiry lessons and to be better focused on improving science education for a wide diversity of students. Through these workshops faculty use a backwards faded scaffolding mechanism for working inquiry into a deeper understanding of science by using existing on-line data to develop and research astronomy, progressing from creating a valid and easily testable question, to simple data analysis, arriving at a conclusion, and finally presenting and supporting that conclusion in the classroom.

Monticello, Thomas M

2015-01-01

The International Consortium for Innovation and Quality (IQ) in Pharmaceutical Development is a science-focused organization of pharmaceutical and biotechnology companies. The mission of the Preclinical Safety Leadership Group (DruSafe) of the IQ is to advance science-based standards for nonclinical development of pharmaceutical products and to promote high-quality and effective nonclinical safety testing that can enable human risk assessment. DruSafe is creating an industry-wide database to determine the accuracy with which the interpretation of nonclinical safety assessments in animal models correctly predicts human risk in the early clinical development of biopharmaceuticals. This initiative aligns with the 2011 Food and Drug Administration strategic plan to advance regulatory science and modernize toxicology to enhance product safety. Although similar in concept to the initial industry-wide concordance data set conducted by International Life Sciences Institute's Health and Environmental Sciences Institute (HESI/ILSI), the DruSafe database will proactively track concordance, include exposure data and large and small molecules, and will continue to expand with longer duration nonclinical and clinical study comparisons. The output from this work will help identify actual human and animal adverse event data to define both the reliability and the potential limitations of nonclinical data and testing paradigms in predicting human safety in phase 1 clinical trials. © 2014 by The Author(s).

In 2010, the U.S. National Aeronautics and Space Administration (NASA) initiated the Air Quality Applied Science Team (AQAST) as a 5-year, $17.5-million award with 19 principal investigators. AQAST aims to increase the use of Earth science products in air quality-related research and to help meet air quality managers' information needs. We conducted a Web-based survey and a limited number of follow-up interviews to investigate federal, state, tribal, and local air quality managers' perspectives on usefulness of Earth science data and models, and on the impact AQAST has had. The air quality managers we surveyed identified meeting the National Ambient Air Quality Standards for ozone and particulate matter, emissions from mobile sources, and interstate air pollution transport as top challenges in need of improved information. Most survey respondents viewed inadequate coverage or frequency of satellite observations, data uncertainty, and lack of staff time or resources as barriers to increased use of satellite data by their organizations. Managers who have been involved with AQAST indicated that the program has helped build awareness of NASA Earth science products, and assisted their organizations with retrieval and interpretation of satellite data and with application of global chemistry and climate models. AQAST has also helped build a network between researchers and air quality managers with potential for further collaborations. NASA's Air Quality Applied Science Team (AQAST) aims to increase the use of satellite data and global chemistry and climate models for air quality management purposes, by supporting research and tool development projects of interest to both groups. Our survey and interviews of air quality managers indicate they found value in many AQAST projects and particularly appreciated the connections to the research community that the program facilitated. Managers expressed interest in receiving continued support for their organizations' use of satellite data, including assistance in retrieving and interpreting data from future geostationary platforms meant to provide more frequent coverage for air quality and other applications.

"Know Your Well" A Groundwater Quality Project to Inform Students and Well-Owners

Olson, C.; Snow, D.; Samal, A.; Ray, C.; Kreifels, M.

2017-12-01

Over 15 million U.S. households rely on private, household wells for drinking water, and these sources are not protected under the Safe Drinking Water Act. Data on private well water quality is slowly being collected and evaluated from a number of different agencies, sources and projects. A new project is designed both for training high school students and to help assess the quality of water from rural domestic wells in Nebraska. This "crowd sourced" program engaging high school agricultural education programs, FFA chapters, and science classes with students sampling and testing water sampling from rural domestic wells from 12 districts across the state. Students and teachers from selected school were trained through multiple school visits, both in the classroom and in the field. Classroom visits were used to introduce topics such as water quality and groundwater, and testing methods for specific analytes. During the field visit, students were exposed to field techniques, the importance of accuracy in data collection, and what factors might influence the water in sampled wells. High school students learn to sample and test water independently. Leadership and initiative is developed through the program, and many experience the enlightenment that comes with citizen science. A customized mobile app was developed for ease of data entry and visualization, and data uploaded to a secure website where information was stored and compared to laboratory tests of the same measurements. General water quality parameters, including pH, electrical conductivity, major anions are tested in the field and laboratory, as well as environmental contaminants such as arsenic, uranium, pesticides, bacteria. Test kits provided to each class were used by the students to measure selected parameters, and then duplicate water samples were analyzed at a university laboratory. Five high schools are involved in the project during its first year. Nitrate, bacteria and pesticides represent major concerns for private well owners across the U.S. and preliminary results indicate that nitrate concentrations can range up to 70 mg/L, while detections of bacteria and traces of pesticide residues are consistent with other studies. This project will help both high school students and private well owner become better-informed about water quality in Nebraska.

Even with recent scientific advancements, challenges posed by limited resources and capabilities at the time of sample dissection continue to limit the collection of high quality tissues from experiments that can be conducted only infrequently and at high cost, such as in space. The resources and time it takes to harvest tissues post-euthanasia, and the methods and duration of long duration storage, potentially have negative impacts on sample quantity and quality, thereby limiting the scientific outcome that can be achieved. The goals of this study were to optimize methods for both sample recovery and science return from rodent experiments, with possible relevance to both ground based and spaceflight studies. The first objective was to determine the impacts of tissue harvest time post-euthanasia, preservation methods, and storage duration, focusing on RNA quality and enzyme activities in liver and spleen as indices of sample quality. The second objective was to develop methods that will maximize science return by dissecting multiple tissues after long duration storage in situ at -80°C. Tissues of C57Bl/6J mice were dissected and preserved at various time points post-euthanasia and stored at -80°C for up to 11 months. In some experiments, tissues were recovered from frozen carcasses which had been stored at -80°C up to 7 months. RNA quantity and quality was assessed by measuring RNA Integrity Number (RIN) values using an Agilent Bioanalyzer. Additionally, the quality of tissues was assessed by measuring activities of hepatic enzymes (catalase, glutathione reductase and GAPDH). Fresh tissues were collected up to one hour post-euthanasia, and stored up to 11 months at -80°C, with minimal adverse effects on the RNA quality of either livers or RNAlater-preserved spleens. Liver enzyme activities were similar to those of positive controls, with no significant effect observed at any time point. Tissues dissected from frozen carcasses that had been stored for up to 7 months at -80°C had variable results, depending on the specific tissue analyzed. RNA quality of liver, heart, and kidneys were minimally affected after 6-7 months of storage at -80°C, whereas RNA degradation was evident in tissues such as small intestine, bone, and bone marrow when they were collected from the carcasses frozen for 2.5 months. These results demonstrate that 1) the protocols developed for spaceflight experiments with on-orbit dissections support the retrieval of high quality samples for RNA expression and some protein analyses, despite delayed preservation post-euthanasia or prolonged storage, and 2) many additional tissues for gene expression analysis can be obtained by dissection even following prolonged storage of the tissue in situ at -80°C. These findings have relevance both to high value, ground-based experiments when sample collection capability is severely constrained, and to spaceflight experiments that entail on-orbit sample recovery by astronauts.

Introduction: High quality educational systems are necessary for sustainable development and responding to the needs of society. In the recent decades, concerns have increased on the quality of education and competency of graduates. Since graduates of medical education are directly involved with the health of society, the quality of this system is of high importance. Investigation in the lived experience of educational leaders in the medical education systems can help to promote its quality. The present research examines this issue in Iran. Methodology: The study was done using content-analysis qualitative approach and semi-structured interviews. The participants included 26 authorities including university chancellors and vice-chancellors, ministry heads and deputies, deans of medical and basic sciences departments, education expert, graduates, and students of medical fields. Sampling was done using purposive snowball method. Data were analyzed using conventional content analysis. Findings: Five main categories and 14 sub-categories were extracted from data analysis including: quantity-orientation, ambiguity in the trainings, unsuitable educational environment, personalization of the educational management, and ineffective interpersonal relationship. The final theme was identified as “Education in shadow”. Conclusion: Personalization and inclusion of personal preferences in management styles, lack of suitable grounds, ambiguity in the structure and process of education has pushed medical education toward shadows and it is not the first priority; this can lead to incompetency of medical science graduates.

Vice Presidents' Foreword

NASA Astrophysics Data System (ADS)

Dear Reader, In the early sixties, the eminent American hydrologist, Walter Langbein, founded Water Resources Research on behalf of the Section of Hydrology of the American Geophysical Union (AGU). Today, Water Resources Research is undisputed as the leading international journal in its field, and the key factors in its success are: * sustained emphasis on high quality papers; * the reviewing, editing, and management processes are all controlled by the scientists; * the allegiance of the AGU community to WRR; * a verv reasonable cost both to institutions and members; * financial benefits from the sales of the journal are fed back to the AGU, to the benefit of the members. In Europe, we now have a well established community of hydrologists in EGS, and the need for a high quality journal was addressed initially by adopting the already well established Elsevier journal of Hydrology as the official journal of the Hydrological Sciences Section. However, it became apparent that several of the factors associated with WRR's success were not working in the Society's favour, and so it has been decided to establish a new journal which, we hope, can emulate the success of WRR in the fullness of time. Much has been written over the past decade about the need to establish a strong identity for hydrology as a distinct geoscience alongside the atmospheric, ocean and solid earth sciences. The aims and scope of Hydrology and Earth System Sciences (HESS) have been designed to give full expression to this goal, and have been strongly influenced by 'Opportunities in the Hydrologic Sciences' (National Academy Press,1991). The functioning of the hydrological cycle within an earth system undergoing global change is currently the focus of research by many leading scientists and it is hoped that HESS will become a major forum for the publication and discussion of such research, as well as all new findings which enhance the position of hydrology as a geoscience. The success of a new journal is dependent not only on attracting high quality papers, but on the preservation of high standards in the overall editorial process. This requires, inter alia, a sympathetic managing editor to assist non-native English speakers in Europe and beyond to communicate their research findings with good clarity. We are highly fortunate that Dr j S G (Jim) McCulloch, who has had such a major impact on the success of the Journal of Hydrology, has agreed to take on the onerous task of launching and managing HESS. He will be supported by a panel of Scientific Editors and by an Editorial Board, who will advise him. We are indebted to Dr McCulloch and his editorial office team for their dedicated efforts in bringing this first issue to fruition. We also thank the authors, who have entrusted their papers to HESS, the reviewers who have responded so promptly and Arne Richter, the Secretary-General of EGS, for his continual support and enthusiasm for this venture. Finally, and most important of all, we appeal to you, and all members of the scientific community, to support HESS by * taking out a personal subscription; * arranging for an institutional subscription; * contributing your best papers; * helping with the peer review process. By rallying around HESS and giving it the priority which will ensure that high quality is achieved from the outset, we can, as a community, eventually match the achievements of WRR. You and future generations of European hydrologists will be the beneficiaries. Philip O'Kane Enda O'Connell EGS Vice-President Past-EGS Vice-President (Hydrological Sciences) (Hydrological Sciences)

Investigation of Mechanism of Action of Modifying Admixtures Based on Products of Petrochemical Synthesis on Concrete Structure

The creation of composite materials for generating structural elements with the desired properties has always been and still remains relevant. The basis of a modern concrete technology is the creation of a high-quality artificial stone characterized by low defectiveness and structure stability. Improving the quality of concrete compositions can be achieved by using chemical admixtures from local raw materials which is a very promising task of modern materials’ science for creation of a new generation of concretes. The new generation concretes are high-tech, high-quality, multicomponent concrete mixes and compositions with admixtures that preserve the required properties in service under all operating conditions. The growing complexity of concrete caused by systemic effects that allow you to control the structure formation at all stages of the technology ensures the obtaining of composites with "directional" quality, compositions, structure and properties. The possibility to use the organic fraction of oil refining as a multifunctional hydrophobic-plasticizing admixture in the effective cement concrete is examined.

Exploring Antarctic Land Surface Temperature Extremes Using Condensed Anomaly Databases

NASA Astrophysics Data System (ADS)

Grant, Glenn Edwin

Satellite observations have revolutionized the Earth Sciences and climate studies. However, data and imagery continue to accumulate at an accelerating rate, and efficient tools for data discovery, analysis, and quality checking lag behind. In particular, studies of long-term, continental-scale processes at high spatiotemporal resolutions are especially problematic. The traditional technique of downloading an entire dataset and using customized analysis code is often impractical or consumes too many resources. The Condensate Database Project was envisioned as an alternative method for data exploration and quality checking. The project's premise was that much of the data in any satellite dataset is unneeded and can be eliminated, compacting massive datasets into more manageable sizes. Dataset sizes are further reduced by retaining only anomalous data of high interest. Hosting the resulting "condensed" datasets in high-speed databases enables immediate availability for queries and exploration. Proof of the project's success relied on demonstrating that the anomaly database methods can enhance and accelerate scientific investigations. The hypothesis of this dissertation is that the condensed datasets are effective tools for exploring many scientific questions, spurring further investigations and revealing important information that might otherwise remain undetected. This dissertation uses condensed databases containing 17 years of Antarctic land surface temperature anomalies as its primary data. The study demonstrates the utility of the condensate database methods by discovering new information. In particular, the process revealed critical quality problems in the source satellite data. The results are used as the starting point for four case studies, investigating Antarctic temperature extremes, cloud detection errors, and the teleconnections between Antarctic temperature anomalies and climate indices. The results confirm the hypothesis that the condensate databases are a highly useful tool for Earth Science analyses. Moreover, the quality checking capabilities provide an important method for independent evaluation of dataset veracity.

Raynien Kwo, J.

2010-03-01

Started about two decades ago, the global trend of shifting industrial manufacture power from western developed countries toward developing countries in Asia has in turn become the impetus in building up physical science and research in these areas. A very good example is the remarkable progress of physical research and education in Taiwan, in terms of quantity and quality. The continuous elevation of Taiwan's high education into graduate level plus the government's strong commitment to research and development on a level of 2.62 % GDP have led to an impressive physics program with an annual budget ˜32 million USD from National Science Council in supporting 568 PIs. The investigation scope encompasses high energy and astrophysics, nano and condensed matter, and semiconductor, optoelectronic physics, etc. The former is vigorously conducted via international collaborative efforts of LHC, KEK, ALMA, Pan-STARRS, etc. The latter is driven by vital Taiwan high tech industry mostly semiconductor IC and optoelectronics flourished during this period. The early trend of outflows of BS physics majors to western world for advanced studies has reversed dramatically. Nearly 80% of the BS students continue their MS and PhD degrees in Taiwan, attracted by lucrative job markets of high tech industry. In addition, healthy inflow of high-quality science manpower of well trained PhDs and senior scholars returning to homeland has strengthened the competitiveness. Overall, the physics community in Taiwan is thriving. The annual Physical Society meeting is expanding at a rate of 6%, reaching ˜1800 attendants and 1200 papers, and dedicated to promotions of female physicists and students. The publication quantity of Taiwan in top journals of PRs and PRL is ranked among top 20^th for all fields of physics, and ranked the 6^th in APL. Clearly Taiwan has now emerged as a strong power in applied science, not limited by its population size. Concerted efforts on scientific exchanges are being taken to connect to international societies. The bright outlook of physical science and its vital power in Taiwan is anticipated to provide a stimulus to benefit South East Asia, and have far-reaching impacts on China and worldwide.

In this article, we describe how teachers in the Australian school system are educated to teach science and the different qualifications that teachers need to enter the profession. The latest comparisons of Australian students in international science assessments have brought about various accountability measures to improve the quality of science teachers at all levels. We discuss the issues and implications of government initiatives in preservice and early career teacher education programs, such as the implementation of national science curriculum, the stricter entry requirements to teacher education programs, an alternative pathway to teaching and the measure of effectiveness of teacher education programs. The politicized discussion and initiatives to improve the quality of science teacher education in Australia are still unfolding as we write in 2014.

A 100-Year Review: Cheese production and quality.

PubMed

Johnson, M E

2017-12-01

In the beginning, cheese making in the United States was all art, but embracing science and technology was necessary to make progress in producing a higher quality cheese. Traditional cheese making could not keep up with the demand for cheese, and the development of the factory system was necessary. Cheese quality suffered because of poor-quality milk, but 3 major innovations changed that: refrigeration, commercial starters, and the use of pasteurized milk for cheese making. Although by all accounts cold storage improved cheese quality, it was the improvement of milk quality, pasteurization of milk, and the use of reliable cultures for fermentation that had the biggest effect. Together with use of purified commercial cultures, pasteurization enabled cheese production to be conducted on a fixed time schedule. Fundamental research on the genetics of starter bacteria greatly increased the reliability of fermentation, which in turn made automation feasible. Demand for functionality, machinability, application in baking, and more emphasis on nutritional aspects (low fat and low sodium) of cheese took us back to the fundamental principles of cheese making and resulted in renewed vigor for scientific investigations into the chemical, microbiological, and enzymatic changes that occur during cheese making and ripening. As milk production increased, cheese factories needed to become more efficient. Membrane concentration and separation of milk offered a solution and greatly enhanced plant capacity. Full implementation of membrane processing and use of its full potential have yet to be achieved. Implementation of new technologies, the science of cheese making, and the development of further advances will require highly trained personnel at both the academic and industrial levels. This will be a great challenge to address and overcome. Copyright © 2017 American Dairy Science Association. Published by Elsevier Inc. All rights reserved.

From the field and lab to data wrangling and facilitating interagency collaboration- how I ended up in the data science world.

Kreft, J.

2015-12-01

I work to build systems that make environmental data more accessible and usable for others—a role that I love and, ten years ago, would not have guessed I would play. I transitioned from conducting pure research to learning more about data curation and information science, and eventually, to combining knowledge of both the research and data science worlds in my current position at the U.S. Geological Survey Center for Integrated Data Analytics (USGS CIDA). At the USGS, I primarily work on the Water Quality Portal, an interagency tool for providing high performance, standards driven access to water quality data, and the USGS Publications Warehouse, which plays a key and ever expanding role in providing access to USGS Publications and their associated data sets. Both projects require an overarching focus on building services to make science data more visible and accessible to users. In addition, listening to the needs of the research scientists who are both collecting and using the data to improve the tools I guide the development of. Concepts that I learned at the University Of Illinois at Urbana-Champaign Graduate School of Library and Information Science Data Curation Education Program were critical to a successful transition from the research world to the data science world. Data curation and data science are playing an ever-larger role in surmounting current and future data challenges at the USGS, and the need for people with interests in both research and data science will continue to grow.

The Marine Geoscience Data System Media Bank (http://media.marine-geo.org) was constructed to enable the sharing of high quality images, illustrations and animations among members of the science community and to provide a new forum for education and public outreach (EPO). The initial focus of Media Bank was to serve Ridge 2000 research and EPO efforts, but it was constructed as a flexible system that could accommodate media from other multidisciplinary marine geoscience research initiatives. Media Bank currently contains digital photographs, maps, 3-D visualizations, and video clips from the Ridge 2000 and MARGINS focus sites as well as the Antarctic and Southern Ocean. We actively seek contributions of other high quality marine geoscience media for inclusion in Media Bank. Media Bank is driven by a relational database backend, enabling image browsing, sorting by category, keyword search functionality, and the creation of media galleries. All media are accompanied by a descriptive figure caption that provides easy access to expert knowledge to help foster data integration across disciplines as well as EPO efforts. In addition to access to high quality media, Media Bank also provides basic metadata including geographic position, investigator name and affiliation, as well as copyright information, and links to references and relevant data sets. Since media are tied to geospatial coordinates, a map-based interface is also provided for access to media.

The physical environment is of particular importance for supporting activities and interactions among older people living in residential care facilities (RCFs) who spend most of their time inside the facility. More knowledge is needed regarding the complex relationships between older people and environmental aspects in long-term care. The present study aimed to explore how the physical environment influences resident activities and interactions at two RCFs by using a mixed-method approach. Environmental assessments were conducted via the Swedish version of the Sheffield Care Environment Assessment Matrix (S-SCEAM), and resident activities, interactions and locations were assessed through an adapted version of the Dementia Care Mapping (DCM). The Observed Emotion Rating Scale (OERS) was used to assess residents' affective states. Field notes and walk-along interviews were also used. Findings indicate that the design of the physical environment influenced the residents' activities and interactions. Private apartments and dining areas showed high environmental quality at both RCFs, whereas the overall layout had lower quality. Safety was highly supported. Despite high environmental quality in general, several factors restricted resident activities. To optimise care for older people, the design process must clearly focus on accessible environments that provide options for residents to use the facility independently. © 2016 The Authors.

Air pollution, responsible for more deaths each year than HIV/AIDS and malaria, combined, is a global public health crisis. Yet many scientific questions, including those directly relevant for policy, remain unanswered when it comes to the impact of air pollution on health in highly polluted environments. Often, specific solutions to improving air quality are local and sustained through public engagement, policy and monitoring. Both the overarching science of air quality and health and local solutions rely on access to reliable, timely air quality data. Over the past year, the OpenAQ community has opened up existing disparate air quality data in 24 countries through an open source platform (openaq.org) so that communities around the world can use it to advance science, public engagement, and policy. We will share stories of communities, from Delhi to Ulaanbaatar and from scientists to journalists, using open air quality data from our platform to advance their fight against air inequality. We will share recent research we have conducted on best practices for engaging different communities and building tools that enable the public to fully unleash the power of open air quality data to fight air inequality. The subsequent open-source tools (github.com/openaq) we have developed from this research and our entire data-sharing platform may be of interest to other open data communities.

Academic burnout leads to creation of a series of negative and scattered thoughts, loss of hope and emotional and physical exhaustion in carrying out activities. Two factors that affect academic burnout are sleep quality and social intimacy. This study was conducted in order to investigate the relationship between sleep quality and social intimacy, and academic burn-out in the students of Tabriz University of Medical Sciences. This study was descriptive and correlational. The population of this study consisted of the students in Tabriz University of Medical Sciences and 196 medical students were selected. They completed Berso et al. Academic Burnout Questionnaire, Pittsburgh Sleep Quality Index (PSQI) and Miller Social Intimacy Scale (MSIS). The validity of the questionnaires confirmed by experts' views. Their reliability were obtained as 77%, 64% and 85% for academic burnout, sleep quality and social intimacy questionnaires respectively by calculating the internal consistency (Cronbach's alpha). For data analysis, descriptive statistics and Pearson correlation test, Regression, cluster analysis and t-test were used. The results showed that there was a positive and significant relationship between sleep quality and academic burnout at the level p<0.05 (r=0.38). There was a negative and significant relationship between social intimacy and academic burnout at the level p<0.05 (r= -0.40). Also, the regression results showed that sleep quality and social intimacy were able to predict 37% and 39% of academic burnout respectively. Moreover, the students were divided into two clusters of individuals with high social intimacy and individuals with low social intimacy. No significant difference was found between the two types in terms of the variable of academic burn-out. Based on the research results, it can be stated that the variables of sleep quality and social intimacy are the predictor factors of academic burn-out.

Education in cardiopulmonary resuscitation in Russia: A systematic review of the available evidence

PubMed Central

Birkun, Alexei; Glotov, Maksim

2017-01-01

BACKGROUND: To summarise and appraise cumulative published scientific evidence relevant to cardiopulmonary resuscitation (CPR) education in Russia. DATA RESOURCES: We searched Medline, Scopus, Science Direct and Russian Science Citation Index databases from December 1991 to December 2016 to identify studies pertaining to the field of CPR education that were carried out by Russian researchers and/or investigated the topic of interest for Russia/Russian population. Reference lists of eligible publications, contents pages of relevant Russian journals and Google Scholar were also searched. There was no limitation based on publication language or study design. RESULTS: Of 7 964 unique citations identified, 22 studies were included. All studies were published from 2009 to 2016, mainly in Russian. Only three studies were reported to be randomized controlled. Non-medical individuals constituted 17% of studied populations. Most of the studies aimed to assess effects of CPR educational interventions, generally suggesting positive influence of the training conducted. The studies were highly heterogeneous as for methodological approaches, structure and duration of educational interventions, evaluation methods and criteria being used. Methodological quality was generally poor, with >40% publications not passing quality screening and only 2 studies meeting the criteria of moderate high quality. CONCLUSION: The results suggest paucity, low population coverage, high thematic and methodological heterogeneity and low quality of the studies addressing CPR education, which were carried out in the Russian Federation. There is a critical need in conducting methodologically consistent, large-scale, randomized, controlled studies evaluating and comparing efficiency of educational interventions for teaching CPR in different population categories of Russia.

Kong, Qi; Qin, Chuan

2009-01-01

Laboratory animal science (LAS) advances scientific understanding of the care and use of animals that play a key role in research supporting the development of biomedicine. LAS has developed quickly in China in recent decades, and this report provides an analysis of the current status of the countrys LAS policies and administration. National and provincial laws, regulations, guidelines, and standards apply to quality control and licensing, quarantine and infectious disease control, breeding and husbandry, transgenic animals, staff qualifications, animal welfare, and imports, exports, and transportation. Regulation and oversight of lab animal use are the responsibility of the national Ministry of Science and Technology, provincial departments of science and technology, and institutional animal care and use committees. We begin with an explanation of the rationale behind this paper and then offer a brief history of policy-related activities and achievements. We then present various policies, discuss their implementation, and hypothesize about future policy developments. With the improvement of policies under an integrated, multitiered administration, the use of high-quality lab animals in Chinese scientific research is increasing and many more papers describing animal experiments performed in China are being published in international journals.

To document the integration of social science theory in literature on mHealth (mobile health) and consider opportunities for integration of classic theory, health communication theory, and social networking to generate a relevant theory for mHealth program design. A secondary review of research syntheses and meta-analyses published between 2005 and 2014 related to mHealth, using the AMSTAR (A Measurement Tool to Assess Systematic Reviews) methodology for assessment of the quality of each review. High-quality articles from those reviews using a randomized controlled design and integrating social science theory in program design, implementation, or evaluation were reviewed. Results There were 1,749 articles among the 170 reviews with a high AMSTAR score (≥30). Only 13 were published from 2005 to 2014, used a randomized controlled design and made explicit mention of theory in any aspect of their mHealth program. All 13 included theoretical perspectives focused on psychological and/or psychosocial theories and constructs. Conclusions There is a very limited use of social science theory in mHealth despite demonstrated benefits in doing so. We propose an integrated theory of mHealth that incorporates classic theory, health communication theory, and social networking to guide development and evaluation of mHealth programs. © 2015 Society for Public Health Education.

This is a Space Shuttle Columbia (STS-65) onboard photo of the second International Microgravity Laboratory (IML-2) in the cargo bay with Earth in the background. Mission objectives of IML-2 were to conduct science and technology investigations that required the low-gravity environment of space, with emphasis on experiments that studied the effects of microgravity on materials processes and living organisms. Materials science and life sciences are two of the most exciting areas of microgravity research because discoveries in these fields could greatly enhance the quality of life on Earth. If the structure of certain proteins can be determined by examining high-quality protein crystals grown in microgravity, advances can be made to improve the treatment of many human diseases. Electronic materials research in space may help us refine processes and make better products, such as computers, lasers, and other high-tech devices. The 14-nation European Space Agency (ESA), the Canadian Space Agency (SCA), the French National Center for Space Studies (CNES), the German Space Agency and the German Aerospace Research Establishment (DARA/DLR), and the National Space Development Agency of Japan (NASDA) participated in developing hardware and experiments for the IML missions. The missions were managed by NASA's Marshall Space Flight Center. The Orbiter Columbia was launched from the Kennedy Space Center on July 8, 1994 for the IML-2 mission.

2009-08-01

The goal of this study was to determine whether computerized tomographic (CT) images of cadavers could be used in addition to images from patients to develop virtual patients (VPs) to enhance integrated learning of basic and clinical science. We imaged 13 cadavers on a Siemens CT system. The DICOM images from the CT were noted to be of high quality by a radiologist who systematically identified all abnormal and pathological findings. The pathological findings from the CT images and the cause of death were used to develop plausible clinical cases and study questions. Each case was designed to highlight and explain the abnormal anatomic findings encountered during the cadaveric dissection. A 3D reconstruction was produced using OsiriX and then formatted into a QuickTime movie which was then stored on the Tufts University Sciences Knowledgebase (TUSK) as a VP. We conclude that CT scanning of cadavers produces high-quality images that can be used to develop VPs. Although the use of the VPs was optional and fewer than half of the students had an imaged cadaver for dissection, 59 of the 172 (34%) students accessed and reviewed the cases and images positively and were very encouraging for us to continue.

Profit, Jochen; Zupancic, John A. F.; Gould, Jeffrey B.; Petersen, Laura A.

2011-01-01

Pay-for-performance initiatives in medicine are proliferating rapidly. Neonatal intensive care is a likely target for these efforts because of the high cost, available databases, and relative strength of evidence for at least some measures of quality. Pay-for-performance may improve patient care but requires valid measurements of quality to ensure that financial incentives truly support superior performance. Given the existing uncertainty with respect to both the effectiveness of pay-for-performance and the state of quality measurement science, experimentation with pay-for-performance initiatives should proceed with caution and in controlled settings. In this article, we describe approaches to measuring quality and implementing pay-for-performance in the NICU setting. PMID:17473099

Portable color multimedia training systems based on monochrome laptop computers (CBT-in-a-briefcase), with spinoff implications for video uplink and downlink in spaceflight operations

This report describes efforts to use digital motion video compression technology to develop a highly portable device that would convert 1990-91 era IBM-compatible and/or MacIntosh notebook computers into full-color, motion-video capable multimedia training systems. An architecture was conceived that would permit direct conversion of existing laser-disk-based multimedia courses with little or no reauthoring. The project did not physically demonstrate certain critical video keying techniques, but their implementation should be feasible. This investigation of digital motion video has spawned two significant spaceflight projects at MSFC: one to downlink multiple high-quality video signals from Spacelab, and the other to uplink videoconference-quality video in realtime and high quality video off-line, plus investigate interactive, multimedia-based techniques for enhancing onboard science operations. Other airborne or spaceborne spinoffs are possible.

An alternative path to improving university Earth science teaching and developing the geoscience workforce: Postdoctoral research faculty involvement in clinical teacher preparation

It is estimated that by the year 2020 relative to 2009, there will be 28% more Earth Science jobs paying ≥ $75,000/year1 in the U.S.A. These jobs will require advanced degrees, but compared to all arts and science advanced degrees, the number of physical science M.S. and Ph.D. awarded per year decreased from 2.5% in 1980 to 1.5% in 20092. This decline is reflected on a smaller scale and at a younger age: in the New York City school system only 36% of all 8th graders have basic proficiency in science 3. These figures indicate that the lack achievement in science starts at a young age and then extends into higher education. Research has shown that students in grades 7 - 12 4,5 and in university level courses 6 both respond positively to high quality science teaching. However, much attention is focused on improving science teaching in grades 7- 12, whereas at many universities lower level science courses are taught by junior research and contingent faculty who typically lack formal training, and sometimes interest, in effective teaching. The danger here is that students might enter university intending to pursue geoscience degrees, but then encounter ineffective instructors, causing them to lose interest in geoscience and thus pursue other disciplines. The crux of the matter becomes how to improve the quality of university-level geoscience teaching, without losing sight of the major benchmark of success for research faculty - scholarly publications reporting innovative research results. In most cases, it would not be feasible to sidetrack the research goals of early career scientists by placing them into a formal teacher preparation program. But what happens when postdoctoral research scientists take an active role in clinical teacher preparation as part of their research appointments? The American Museum of Natural History's Masters of Arts in Teaching (AMNH-MAT) urban residency pilot program utilizes a unique approach to grade 7 - 12 Earth Science teacher preparation in that postdoctoral research scientists are directly involved in the clinical preparation of the teacher candidates7. In this program, professional educators and senior scientists guide and work closely with the postdoctoral scientists in developing lessons and field experiences for the teacher candidates. This exposes the postdoctoral scientists to pedagogical techniques. Furthermore, postdoctoral scientists make regular visits to partner schools and share their research interests with high school science students8. Regular assessments about the quality of the postdoctoral scientist's teaching, in the form of course evaluations and informal discussions with the teacher candidates and professional educators, further augments the postdoctoral scientists teaching skills. These experiences can ultimately improve university level science teaching, should the postdoctoral scientists find positions within a university setting. Here, five postdoctoral researchers present self-studies of changing instructional practice born of their involvement in clinical teacher preparation in the AMNH-MAT program.

Eason, Martin P

2013-12-01

To assess the current use of simulation in medical education, specifically, the teaching of the basic sciences to accomplish the goal of improved integration. Simulation is increasingly being used by the institutions to teach the basic sciences. Preliminary data suggest that it is an effective tool with increased retention and learner satisfaction. Medical education is undergoing tremendous change. One of the directions of that change is increasing integration of the basic and clinical sciences to improve the efficiency and quality of medical education, and ultimately to improve the patient care. Integration is thought to improve the understanding of basic science conceptual knowledge and to better prepare the learners for clinical practice. Simulation because of its unique effects on learning is currently being successfully used by many institutions as a means to produce that integration through its use in the teaching of the basic sciences. Preliminary data indicate that simulation is an effective tool for basic science education and garners high learner satisfaction.

2012-12-01

Using traditional bibliometric indices such as the well-known journal impact factor (IFAC), as well as other more recently developed measures like the (journal) h-index and modifications, we assessed the impact of most prolific scientific journals in the field of animal and dairy science. To achieve this end, we performed a detailed investigation on the evaluation of journals quality, using a total of 50 journals selected from the category of "Agriculture, Dairy & Animal Science" included in the Thomson Reuters' (formerly Institute of Scientific Information, ISI) Web of Science. Our analysis showed that among the top journals in the field are the Journal of Dairy Research, the Journal of Dairy Science, and the Journal of Animal Science. In particular, the Journal of Animal Science, the most productive and frequently cited journal, has shown rapid development, especially in recent years. The majority of the top-tier, highly cited articles are those associated with the description of statistical methodology and the standard chemical analytical methodologies.

Safari Science: Assessing the reliability of citizen science data for wildlife surveys

USGS Publications Warehouse

Steger, Cara; Butt, Bilal; Hooten, Mevin B.

2017-01-01

Protected areas are the cornerstone of global conservation, yet financial support for basic monitoring infrastructure is lacking in 60% of them. Citizen science holds potential to address these shortcomings in wildlife monitoring, particularly for resource-limited conservation initiatives in developing countries – if we can account for the reliability of data produced by volunteer citizen scientists (VCS).This study tests the reliability of VCS data vs. data produced by trained ecologists, presenting a hierarchical framework for integrating diverse datasets to assess extra variability from VCS data.Our results show that while VCS data are likely to be overdispersed for our system, the overdispersion varies widely by species. We contend that citizen science methods, within the context of East African drylands, may be more appropriate for species with large body sizes, which are relatively rare, or those that form small herds. VCS perceptions of the charisma of a species may also influence their enthusiasm for recording it.Tailored programme design (such as incentives for VCS) may mitigate the biases in citizen science data and improve overall participation. However, the cost of designing and implementing high-quality citizen science programmes may be prohibitive for the small protected areas that would most benefit from these approaches.Synthesis and applications. As citizen science methods continue to gain momentum, it is critical that managers remain cautious in their implementation of these programmes while working to ensure methods match data purpose. Context-specific tests of citizen science data quality can improve programme implementation, and separate data models should be used when volunteer citizen scientists' variability differs from trained ecologists' data. Partnerships across protected areas and between protected areas and other conservation institutions could help to cover the costs of citizen science programme design and implementation.

The topic of climate change permeates all aspects of our society: the news, household debates, scientific conferences, etc. To provide students with accurate information about climate science and energy awareness, educators require scientifically and pedagogically robust teaching materials. To address this need, the NSF-funded Climate Literacy & Energy Awareness Network (CLEAN) Pathway has assembled a new peer-reviewed digital collection as part of the National Science Digital Library (NSDL) featuring teaching materials centered on climate and energy science for grades 6 through 16. The scope and framework of the collection is defined by the Essential Principles of Climate Science (CCSP 2009) and a set of energy awareness principles developed in the project. The collection provides trustworthy teaching materials on these socially relevant topics and prepares students to become responsible decision-makers. While a peer-review process is desirable for curriculum developer as well as collection builder to ensure quality, its implementation is non-trivial. We have designed a rigorous and transparent peer-review process for the CLEAN collection, and our experiences provide general guidelines that can be used to judge the quality of digital teaching materials across disciplines. Our multi-stage review process ensures that only resources with teaching goals relevant to developing climate literacy and energy awareness are considered. Each relevant resource is reviewed by two individuals to assess the i) scientific accuracy, ii) pedagogic effectiveness, and iii) usability/technical quality. A science review by an expert ensures the scientific quality and accuracy. Resources that pass all review steps are forwarded to a review panel of educators and scientists who make a final decision regarding inclusion of the materials in the CLEAN collection. Results from the first panel review show that about 20% (~100) of the resources that were initially considered for inclusion passed final review. Reviewer comments are recorded as annotations to enhance the resources in the collection and help educators with the implementation in their curriculum. CLEAN launched the first collection of digital educational resources about climate science and energy awareness in November 2010. The final CLEAN collection will include ≥500 resources and will also provide the alignment with the Benchmarks for Science Literacy and the NAAEE Excellence in Environmental Education Guidelines for Learning through the interactive NSDL strandmaps. We will present the first user feedback to this new collection.

What do a snap-bean plant and a future NASA satellite instrument named TEMPO have in common? They are both indicators of the quality of the air we breathe. Scientists, educators, and museum and student collaborators of the Tropospheric Emissions: Monitoring Pollution (TEMPO) instrument team are developing a program model to engage learners of all ages via public ozone garden exhibits and associated activities. TEMPO, an ultraviolet and visible spectroscopy instrument due for launch on a geostationary host satellite between 2019 and 2021, will scan North America hourly to measure the major elements in the tropospheric ozone chemistry cycle, providing near real-time data with high temporal and spatial resolution. The TEMPO mission provides a unique opportunity to share the story of the effects of air quality on living organisms. A public ozone garden exhibit affords an accessible way to understand atmospheric science through a connection with nature, while providing a visual representation of the impact of ozone pollution on living organisms. A prototype ozone garden exhibit was established at the Virginia Living Museum in partnership with NASA Langley, and has served as a site to formatively evaluate garden planting and exhibit display protocols, hands-on interpretive activities, and citizen science data collection protocols for learners as young as 3 to 10 as well as older adults. The fun and engaging activities, optimized for adult-child interaction in informal or free-choice learning environments, are aimed at developing foundational science skills such as observing, comparing, classifying, and collecting and making sense of data in the context of thinking about air quality - all NGSS-emphasized scientific practices, as well as key capabilities for future contributing members of the citizen science community. As the launch of TEMPO approaches, a major public engagement effort will include disseminating this ozone garden exhibit and program model to a network of museums and public gardens across the country, so that learners nationwide participate in a hands-on way and develop the citizen science skills to be able to contribute quantitative and qualitative data on local air-quality impact back to the overall science community.

High-quality laboratory space to support basic science, clinical research projects, or health services is often severely lacking in the developing world. Moreover, the construction of suitable facilities using traditional methods is time-consuming, expensive, and challenging to implement. Three real world examples showing how shipping containers can be converted into modern laboratories are highlighted. These include use as an insectary, a molecular laboratory, and a BSL-3 containment laboratory. These modular conversions have a number of advantages over brick and mortar construction and provide a cost-effective and timely solution to offer high-quality, user-friendly laboratory space applicable within the developing world.

Online citizen science offers a low-cost way to strengthen the infrastructure for scientific research and engage members of the public in science. As the sustainability of online citizen science projects depends on volunteers who contribute their skills, time, and energy, the objective of this study is to investigate effects of motivational factors on the quantity and quality of citizen scientists' contribution. Building on the social movement participation model, findings from a longitudinal empirical study in three different citizen science projects reveal that quantity of contribution is determined by collective motives, norm-oriented motives, reputation, and intrinsic motives. Contribution quality, on the other hand, is positively affected only by collective motives and reputation. We discuss implications for research on the motivation for participation in technology-mediated social participation and for the practice of citizen science. PMID:24690612

The Scripps Classroom Connection, funded through the NSF GK-12 program, pairs local high school teachers with Scripps Institution of Oceanography (SIO) graduate students in the earth and ocean sciences for their mutual professional development. An integral goal of the program is the collaborative production of quality earth science educational modules that are tested in the classroom and subsequently made freely available online for use by other educators. We present a brief overview of the program structure in place to support this goal and illustrate a module that we have developed on the Solid Earth & Plate Tectonics for a 9th grade Earth Science classroom. The unit includes 1) an exercise in constructing a geomagnetic polarity timescale which exposes students to authentic scientific data; 2) activities, labs, lectures and worksheets that support the scientific content; and 3) use of online resources such as Google Earth and interactive animations that help students better understand the concepts. The educational unit is being implemented in two separate local area high schools for Fall 2010 and we will report on our experiences. The co-operative efforts of teachers and scientists lead to educational materials which expose students to the scientific process and current science research, while teaching basic concepts using an engaging inquiry-based approach. In turn, graduate students involved gain experience communicating their science to non-science audiences.

Computational thinking (for example, the thought processes involved in developing algorithmic solutions to problems that can then be automated for computation) has revolutionized the way we do science. The Next Generation Science Standards require that teachers support their students’ development of computational thinking and computational modeling skills. As a result, there is a very high demand among teachers for quality materials. Astronomy provides an abundance of opportunities to support student development of computational thinking skills. Our group has taken advantage of this to create a series of astronomy-based computational thinking lesson plans for use in typical physics, astronomy, and math high school classrooms. This project is funded by the NSF Computing Education for the 21st Century grant and is jointly led by Northwestern University’s Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA), the Computer Science department, the Learning Sciences department, and the Office of STEM Education Partnerships (OSEP). I will also briefly present the online ‘Astro Adventures’ courses for middle and high school students I have developed through NU’s Center for Talent Development. The online courses take advantage of many of the amazing online astronomy enrichment materials available to the public, including a range of hands-on activities and the ability to take images with the Global Telescope Network. The course culminates with an independent computational research project.

Do citations accumulate too slowly in the social sciences to be used to assess the quality of recent articles? I investigate whether this is the case using citation data for all articles in economics and political science published in 2006 and indexed in the Web of Science. I find that citations in the first two years after publication explain more than half of the variation in cumulative citations received over a longer period. Journal impact factors improve the correlation between the predicted and actual future ranks of journal articles when using citation data from 2006 alone but the effect declines sharply thereafter. Finally, more than half of the papers in the top 20% in 2012 were already in the top 20% in the year of publication (2006).

Development of an Instrument to Assess Prospective Elementary Teacher Self-Efficacy Beliefs about Equitable Science Teaching and Learning (SEBEST)

NASA Astrophysics Data System (ADS)

Ritter, Jennifer M.; Boone, William J.; Rubba, Peter A.

2001-06-01

This paper presents an overview of the procedures used to develop and validate an instrument to measure the self-efficacy beliefs of prospective elementary teachers about equitable science teaching and learning. The instrument, titled the SEBEST, was based on the work of Ashton and Webb (1986a, 1986b) and Bandura (1977, 1986). It was modeled after the Science Teaching Efficacy Belief Instrument (STEBI) (Riggs, 1988) and the Science Teaching Efficacy Belief Instrument for Prospective Teachers (STEBI-B) (Enochs & Riggs, 1990). Based on the standardized development procedures used and associated evidence, the SEBEST appears to be a content and construct valid instrument, with high internal reliability qualities. "Most probable response" plots are introduced and used to bring meaning to SEBEST raw scores.

Calculating the quality of public high-throughput sequencing data to obtain a suitable subset for reanalysis from the Sequence Read Archive.

It is important for public data repositories to promote the reuse of archived data. In the growing field of omics science, however, the increasing number of submissions of high-throughput sequencing (HTSeq) data to public repositories prevents users from choosing a suitable data set from among the large number of search results. Repository users need to be able to set a threshold to reduce the number of results to obtain a suitable subset of high-quality data for reanalysis. We calculated the quality of sequencing data archived in a public data repository, the Sequence Read Archive (SRA), by using the quality control software FastQC. We obtained quality values for 1 171 313 experiments, which can be used to evaluate the suitability of data for reuse. We also visualized the data distribution in SRA by integrating the quality information and metadata of experiments and samples. We provide quality information of all of the archived sequencing data, which enable users to obtain sufficient quality sequencing data for reanalyses. The calculated quality data are available to the public in various formats. Our data also provide an example of enhancing the reuse of public data by adding metadata to published research data by a third party. © The Authors 2017. Published by Oxford University Press.

The Decade of Vaccines Collaboration and development of the Global Vaccine Action Plan provides a catalyst and unique opportunity for regulators worldwide to develop and propose a global regulatory science agenda for vaccines. Regulatory oversight is critical to allow access to vaccines that are safe, effective, and of assured quality. Methods used by regulators need to constantly evolve so that scientific and technological advances are applied to address challenges such as new products and technologies, and also to provide an increased understanding of benefits and risks of existing products. Regulatory science builds on high-quality basic research, and encompasses at least two broad categories. First, there is laboratory-based regulatory science. Illustrative examples include development of correlates of immunity; or correlates of safety; or of improved product characterization and potency assays. Included in such science would be tools to standardize assays used for regulatory purposes. Second, there is science to develop regulatory processes. Illustrative examples include adaptive clinical trial designs; or tools to analyze the benefit-risk decision-making process of regulators; or novel pharmacovigilance methodologies. Included in such science would be initiatives to standardize regulatory processes (e.g., definitions of terms for adverse events [AEs] following immunization). The aim of a global regulatory science agenda is to transform current national efforts, mainly by well-resourced regulatory agencies, into a coordinated action plan to support global immunization goals. This article provides examples of how regulatory science has, in the past, contributed to improved access to vaccines, and identifies gaps that could be addressed through a global regulatory science agenda. The article also identifies challenges to implementing a regulatory science agenda and proposes strategies and actions to fill these gaps. A global regulatory science agenda will enable regulators, academics, and other stakeholders to converge around transformative actions for innovation in the regulatory process to support global immunization goals.

Information quality is multidimensional. Four different aspects of information quality can be defined based on the lifecycle stages of Earth Science data products: science, product, stewardship and services. With increasing requirements on ensuring and improving information quality coming from multiple government agencies and throughout industry, there have been considerable efforts toward improving information quality during the last decade, much of which has not been well vetted in a collective sense until recently. Given this rich background of prior work, the Information Quality Cluster (IQC), established within the Federation of Earth Science Information Partners (ESIP) in 2011, and reactivated in the summer of 2014, has been active with membership from multiple organizations. The IQC's objectives and activities, aimed at ensuring and improving information quality for Earth science data and products, are also considered vital toward improving the trustworthiness of Earth science data to a vast and interdisciplinary community of data users. During 2016, several members of the IQC have led the development and assessment of four use cases. This was followed up in 2017 with multiple panel sessions at the 2017 Winter and Summer ESIP Meetings to survey the challenges posed in the various aspects of information quality. What was discovered to be most lacking is the transparency of data lineage (i.e., provenance and maturity), uniform methods for uncertainty characterization, and uniform quality assurance data and metadata. While solutions to these types of issues exist, most data producers have little time to investigate and collaborate to arrive at and conform to a consensus approach. The IQC has positioned itself as a community platform to bring together all relevant stakeholders from data producers, repositories, program managers, and the end users. A combination of both well-vetted and "trailblazing" solutions are presented to address how data trustworthiness can be elevated and maintained through optimized extraction, curation, and dissemination of information quality artifacts.

The International Joint AIRAPT-22 & HPCJ-50 Conference was held in Odaiba, Tokyo, on 26-31 July 2009. About 480 scientists from 24 countries attended the conference and 464 papers, including 3 plenary lectures, 39 invited talks, and 156 oral presentations, were presented. It is my great pleasure to present this proceedings volume, which is based on the high quality scientific works presented at the conference. The International AIRAPT conference has been held every two years in various countries around the world since 1965, while High Pressure Conference of Japan (HPCJ) has been held annually since 1959 in various Japanese cities. Pressure is a fundamental parameter to control the property of matter. As a result, both AIRAPT and HPCJ have become highly multidisciplinary, and cover Physics, Chemistry, Materials Science, Earth and Planetary Sciences, Biosciences, Food Science, and Technology. Although each discipline has a unique target, they all have high-pressure research in common. This proceedings volume includes about 200 papers of state-of-the-art studies from numerous fields. I hope this proceedings volume provides excellent pieces of information in various fields to further advance high-pressure research.

A National Science Foundation Graduate Teaching Fellows in K- 12 Education program at UCLA (SEE-LA; http://measure.igpp.ucla.edu/GK12-SEE-LA/ ) partners UCLA faculty and graduate students (fellows) with urban middle and high school science teachers and their students to foster programs of science and engineering exploration that bring the environment of Los Angeles into the classroom. UCLA science and engineering graduate fellows serve as scientists-in-residence at four partner schools to integrate inquiry-based science lessons, facilitate advancements in science content teaching, and ultimately, to improve their own science communication skills. As part of their fellowship, graduate students are required to develop three "major" lessons, including one based on their PhD research at UCLA. During the first four years of the project, the SEE-LA fellows have developed a range of research-based activities, including lessons on sustainable fisheries, ecosystems and remote sensing, earthquakes, urban water quality including invertebrate observations, and post-fire soil chemistry, among others. This presentation will provide an overview of the SEE-LA GK-12 program and development of research lessons that also address California State Science Standards. We also discuss potential sustainability of GK-12 type outreach and education programs. The SEE-LA program has provided development of graduate student communication and teaching skills while also contributing significantly to the integration of science education into K-12 curriculum in Los Angeles schools.

Science Support: The Building Blocks of Active Data Curation

NASA Astrophysics Data System (ADS)

Guillory, A.

2013-12-01

While the scientific method is built on reproducibility and transparency, and results are published in peer reviewed literature, we have come to the digital age of very large datasets (now of the order of petabytes and soon exabytes) which cannot be published in the traditional way. To preserve reproducibility and transparency, active curation is necessary to keep and protect the information in the long term, and 'science support' activities provide the building blocks for active data curation. With the explosive growth of data in all fields in recent years, there is a pressing urge for data centres to now provide adequate services to ensure long-term preservation and digital curation of project data outputs, however complex those may be. Science support provides advice and support to science projects on data and information management, from file formats through to general data management awareness. Another purpose of science support is to raise awareness in the science community of data and metadata standards and best practice, engendering a culture where data outputs are seen as valued assets. At the heart of Science support is the Data Management Plan (DMP) which sets out a coherent approach to data issues pertaining to the data generating project. It provides an agreed record of the data management needs and issues within the project. The DMP is agreed upon with project investigators to ensure that a high quality documented data archive is created. It includes conditions of use and deposit to clearly express the ownership, responsibilities and rights associated with the data. Project specific needs are also identified for data processing, visualization tools and data sharing services. As part of the National Centre for Atmospheric Science (NCAS) and National Centre for Earth Observation (NCEO), the Centre for Environmental Data Archival (CEDA) fulfills this science support role of facilitating atmospheric and Earth observation data generating projects to ensure successful management of the data and accompanying information for reuse and repurpose. Specific examples at CEDA include science support provided to FAAM (Facility for Airborne Atmospheric Measurements) aircraft campaigns and large-scale modelling projects such as UPSCALE, the largest ever PRACE (Partnership for Advanced Computing in Europe) computational project, dependent on CEDA to provide the high-performance storage, transfer capability and data analysis environment on the 'super-data-cluster' JASMIN. The impact of science support on scientific research is conspicuous: better documented datasets with an increasing collection of metadata associated to the archived data, ease of data sharing with the use of standards in formats and metadata and data citation. These establish a high-quality of data management ensuring long-term preservation and enabling re-use by peer scientists which ultimately leads to faster paced progress in science.

A review of Computer Science resources for learning and teaching with K-12 computing curricula: an Australian case study

NASA Astrophysics Data System (ADS)

Falkner, Katrina; Vivian, Rebecca

2015-10-01

To support teachers to implement Computer Science curricula into classrooms from the very first year of school, teachers, schools and organisations seek quality curriculum resources to support implementation and teacher professional development. Until now, many Computer Science resources and outreach initiatives have targeted K-12 school-age children, with the intention to engage children and increase interest, rather than to formally teach concepts and skills. What is the educational quality of existing Computer Science resources and to what extent are they suitable for classroom learning and teaching? In this paper, an assessment framework is presented to evaluate the quality of online Computer Science resources. Further, a semi-systematic review of available online Computer Science resources was conducted to evaluate resources available for classroom learning and teaching and to identify gaps in resource availability, using the Australian curriculum as a case study analysis. The findings reveal a predominance of quality resources, however, a number of critical gaps were identified. This paper provides recommendations and guidance for the development of new and supplementary resources and future research.

Health care struggles to transfer recent discoveries into high-quality medical care. Therefore, translational science seeks to improve the health of patients and communities by studying and promoting the translation of findings from bench research into clinical care. Similarly, medical education practice may be slow to adopt proven evidence of better learning and assessment. The Academic Emergency Medicine (AEM) consensus conference was designed to promote the dissemination of evidence-based education research and practice. We will pull from the work developed by the consensus conference as a means to create a roadmap for future medical education research using the framework of translational science. © 2012 by the Society for Academic Emergency Medicine.

Discrepant Events: A Challenge to Students' Intuition

NASA Astrophysics Data System (ADS)

González-Espada, Wilson J.; Birriel, Jennifer; Birriel, Ignacio

2010-11-01

Studies on cognitive aspects of science education, especially how students achieve conceptual change, have been a focus of interest for many years. Researchers of student learning and conceptual change have developed several easily applicable teaching strategies. One of these strategies is known as discrepant events. Discrepant events are very powerful ways to stimulate interest, motivate students to challenge their covert science misconceptions, and promote higher-order thinking skills. The key point is that directly challenging students' naive ideas will lead to more quality science learning going on in the classroom. In this paper, we summarize the research-based role of discrepant events in conceptual change and we share several highly successful discrepant events we use in our own classes.

The storage, analysis, and networkmore » resources required to process these data and integrate them into patient diagnoses and treatments have grown to scales that strain the capabilities of academic health centers. Some data are not generated locally and cannot be sustained locally, and shared data repositories such as those provided by the National Library of Medicine, the National Cancer Institute, and international partners such as the European Bioinformatics Institute are rapidly growing. The ability to store and compute using these data must therefore be addressed by a combination of local, national, and industry resources that exchange large datasets. Maintaining data-intensive flows that comply with the Health Insurance Portability and Accountability Act (HIPAA) and other regulations presents a new challenge for biomedical research. We describe a strategy that marries performance and security by borrowing from and redefining the concept of a Science DMZ, a framework that is used in physical sciences and engineering research to manage high-capacity data flows.By implementing a Medical Science DMZ architecture, biomedical researchers can leverage the scale provided by high-performance computer and cloud storage facilities and national high-speed research networks while preserving privacy and meeting regulatory requirements.« less

The storage, analysis, and network resources required to process these data and integrate them into patient diagnoses and treatments have grown to scales that strain the capabilities of academic health centers. Some data are not generated locally and cannot be sustained locally, and shared data repositories such as those provided by the National Library of Medicine, the National Cancer Institute, and international partners such as the European Bioinformatics Institute are rapidly growing. The ability to store and compute using these data must therefore be addressed by a combination of local, national, and industry resources that exchange large datasets. Maintaining data-intensive flows that comply with the Health Insurance Portability and Accountability Act (HIPAA) and other regulations presents a new challenge for biomedical research. We describe a strategy that marries performance and security by borrowing from and redefining the concept of a Science DMZ, a framework that is used in physical sciences and engineering research to manage high-capacity data flows. By implementing a Medical Science DMZ architecture, biomedical researchers can leverage the scale provided by high-performance computer and cloud storage facilities and national high-speed research networks while preserving privacy and meeting regulatory requirements. © The Author 2017.

NASA Astrophysics Data System (ADS)

Venville, Grady

2009-06-01

In this article I initially borrow a metaphor from an art exhibition, Ocean to Outback, as a way to express my perspective on the contribution that Léonie Rennie has made to science education in Australia. I then consider Léonie's contributions as overlapping themes. In particular, Léonie's well-known research on gender and issues of equity in science education is explored as well as her highly regarded work on learning science in out-of-school settings. Curriculum integration is a less well-known aspect of Léonie's research that also is considered. Léonie's important contributions to research training and policy in science education are briefly described and commented on. Finally, I return to the metaphor of Ocean to Outback that reflects the enormity of the contribution that Léonie has made but also gives insight into her personal journey and qualities.

Materials science experiments under microgravity increasingly rely on advanced optical systems to determine the physical properties of the samples under investigation. This includes video systems with high spatial and temporal resolution. The acquisition, handling, storage and transmission to ground of the resulting video data are very challenging. Since the available downlink data rate is limited, the capability to compress the video data significantly without compromising the data quality is essential. We report on the development of a Digital Video System (DVS) for EML (Electro Magnetic Levitator) which provides real-time video acquisition, high compression using advanced Wavelet algorithms, storage and transmission of a continuous flow of video with different characteristics in terms of image dimensions and frame rates. The DVS is able to operate with the latest generation of high-performance cameras acquiring high resolution video images up to 4Mpixels@60 fps or high frame rate video images up to about 1000 fps@512x512pixels.

2013-01-01

The Deep Space Atomic Clock (DSAC) mission will demonstrate the on-orbit performance of a high-accuracy, high-stability miniaturized mercury ion atomic clock during a year-long experiment in Low Earth Orbit. DSAC's timing error requirement provides the frequency stability necessary to perform deep space navigation based solely on one-way radiometric tracking data. Compared to a two-way tracking paradigm, DSAC-enabled one-way tracking will benefit navigation and radio science by increasing the quantity and quality of tracking data. Additionally, DSAC also enables fully-autonomous onboard navigation useful for time-sensitive situations. The technology behind the mercury ion atomic clock and a DSAC mission overview are presented. Example deep space applications of DSAC, including navigation of a Mars orbiter and Europa flyby gravity science, highlight the benefits of DSAC-enabled one-way Doppler tracking.

2010-08-01

The National Optical Astronomy Observatory has led the development of a new telescope kit for kids as part of a strategic plan to interest young children in science. This telescope has been assembled by tens of thousands of children nationwide, who are now using this high-quality telescope to conduct optics experiments and to make astronomical observations. The Galileoscope telescope kit and its associated educational program are an outgrowth of the NSF sponsored "Hands-On Optics" (HOO) project, a collaboration of the SPIE, the Optical Society of America, and NOAO. This project developed optics kits and activities for upper elementary students and has reached over 20,000 middle school kids in afterschool programs. HOO is a highly flexible educational program and was featured as an exemplary informal science program by the National Science Teachers Association. Our new "Teaching with Telescopes" program builds on HOO, the Galileoscope and other successful optical education projects.

Tehran University of Medical Sciences has two streams of medical student admission: an established high school entry (HSE) route and an experimental graduate entry (GE) route. To compare the cognitive skills, personality traits and moral characteristics of HSE and GE students admitted to this university. The personal qualities assessment tool (PQA; www.pqa.net.au ) was translated from English to Persian and then back-translated. Afterwards 35 individuals from the GE and 109 individuals from the 2007 to 2008 HSE completed the test. The results were compared by t-test and Chi-square. The HSE students showed significantly higher ability in the cognitive skills tests (p < 0.001). They were also more libertarian (p = 0.022), but had lower ability to confront stress and unpleasant events (p < 0.001), and had lower self-awareness and self-control (p < 0.001). On the basis of their personal qualities, the GE students had more self-control and strength when coping with stress than the HSE students, but the latter had superior cognitive abilities. Hence it may be useful to include cognitive tests in GE students' entry exam and include tests of personal qualities to exclude those with unsuitable characteristics.

LITERATURE FORENSICS? DOOR TO WHAT WAS KNOWN ...

EPA Pesticide Factsheets

Science's all-consuming drive to make new discoveries often risks losing sight of what was already known at one time - that which already exists in the published literature. Inadequate attention to the published literature and insufficient time devoted to its mining and synthesis into new knowledge is a problem faced by all disciplines, especially highly interdisciplinary fields such as environmental forensics, whose knowledge base is fragmented across numerous disciplines. While the conduct of science applies principles of quality assurance to a wide array of its processes, how pervasive are quality controls designed to ensure that planned or ongoing research has not been undertaken before? Has sufficient energy been devoted to mining what has already been discovered and synthesizing it into a larger, more useful perspective? This paper touches on the liabilities associated with insufficient examination of an exponentially growing published literature (

An exploration of the impact of reform-based science instruction on second graders' academic achievement

NASA Astrophysics Data System (ADS)

Ellis, Valeisha Michelle

The purpose of this study was to examine whether possible relationships might exist between the quality of reform-based science instruction and science and reading achievement in second grade. The study also examined separately possible interactions between quality of instruction and gender and race. The study involved an analysis of data previously collected in a larger one-group pre/post test study of a science instructional intervention (ISI Science) (Connor et al., 2010). In the original study, six teachers and two graduate assistants taught two science units designed based upon constructivist principles and reform-based practices. Using the 5-E Learning Cycle (Bybee, 1997), reading and science were integrated into each lesson. Videotapes were made of all lessons and science and reading achievement data were collected. For the current study, dependent achievement variables were science achievement measured by the Iowa Science Test; reading comprehension, by the Woodcock Passage Comprehension; and vocabulary, by the Iowa Vocabulary. Pre- and post-tests scores on the dependent measures were available for 96 children from the original study. Quality of instruction was measured using the Reformed Teaching Observation Protocol (RTOP) (Sawanda & Piburn, 2000). Videotapes of 24 science lessons from the larger study were analyzed using the RTOP. Reliability of ratings for the RTOP in the study was determined to be .96. No significant results were found for relations between instructional quality (RTOP) and any of the achievement variables although significant pre to post increases on all three measures were observed. No differences by race or gender were found. This latter finding was noteworthy given the research in science identifying both gender and race differences in science achievement. Recommendations for future research and teacher education are discussed.

Neal, C; House, W A; Leeks, G J; Whitton, B A; Williams, R J

2000-05-05

This paper presents an overview of the water quality functioning of eastern UK rivers draining into the North Sea. It summarises the results of three special issues of Science of the Total Environment and related work and complements a companion bibliography (Neal and Turner, 2000, this volume). The rivers are described in straightforward broad terms, and the reader is guided via the bibliography to the special volumes for the detailed findings. The water quality is shown to be highly variable over space and time. The changes over the past 300 years reflect first the transition from a rural society to the major impact of the industrial revolution and subsequently to one of the worlds' most successful environmental cleanups. The present water quality reflects the relative impacts of diffuse agricultural sources, urban and industrial point source discharges together with background inputs associated with geology: all these can be modified by within-river processes associated with physical mixing, biology and inorganic reactions. The work is set within the context of water quality, modelling and flux outputs to the North Sea and contemporary and future environmental research and management needs. A range of environmental impact studies is included. The detailed information is now available on a major and easily accessible database.

Adventures in Citizen Science: Lessons learned engaging volunteer water quality monitors for over 30 years.

The New Hampshire Lakes Lay Monitoring Program was originally designed by faculty at the University of New Hampshire in 1979 to provide the capacity to better monitor for long-term lake water quality changes and trends. As participants became educated, empowered and engaged the program soon evolved to also become a participatory research enterprise. This resulted in not only providing useful information for informed local stewardship and protection at the local level but also for state and region-wide decision-making, state and federal assessments/reporting and advancing our understanding of lake and watershed science. Our successes and failures have been more dependent on understanding the particular human dimensions that influence our volunteers and less to do with the typical project management, quality assurance, and communication concerns we typically deal with in professional based research efforts. Our participants are extremely diverse in terms of their life experiences, interests and motivations so the key to long-term commitment and high quality participation is understanding the difference between a citizen monitor and your archetypical research technician or student. This presentation will highlight some important lessons learned on how to involve various types of volunteers from school groups to retirees, as well as particular approaches and concerns regarding program management, retention, quality control and communications.

A Systematic Review Evaluating the Effect of Vitamin B6 on Semen Quality.

PubMed

Banihani, Saleem Ali

2017-12-30

This review systematically discusses and summarizes the effect of vitamin B6 on semen quality. To achieve this contribution, we searched the PubMed, Scopus, and Web of Science databases for English language papers from 1984 through 2017 using the key words "sperm" versus "Vitamin B6", "pyridoxine", and "pyridoxal". Also, the references from selected published papers were included, only if relevant. To date, as revealed by rodent studies, high doses of vitamin B6 impair semen quality and sperm parameters. While in humans, it is suggested, but not yet directly approved, that seminal vitamin B6 levels may alter sperm quality (i.e., sperm quantity and quality), and that vitamin B6 deficiency may trigger the chemical toxicity to sperm (i.e., hyperhomocysteinemia, oxidative injury). The adverse effect of vitamin B6, when used at high doses, has been revealed in experimental animals, but not yet directly approved in humans. Consequently, in vitro studies on human ejaculate as well as clinical studies that investigate the direct effect of vitamin B6 on semen quality seem very significant.

Enabling Velocity-Resolved Science with Advanced Processing of Herschel/HIFI Observations

NASA Astrophysics Data System (ADS)

Morris, Patrick

The Herschel/HIFI instrument was a heterodyne spectrometer with technology demonstrating and flight components built by NASA/JPL, and acquired over 9000 astronomical observations at velocity resolutions of better than 1 km/s between 480 -1910 GHz (157 - 612 microns). Its performances designed around the scientific goals of exploring the cyclical interrelation of stars and the ISM in diverse environments unified by copious amounts molecular and atomic gas and dust have resulted in over 350 refereed scientific publications, providing a successful foundation and inspiration for current and future science with terahertz instrumentation above the Earth's atmosphere. Nonetheless, almost 60% of the valid observations in the Herschel Science Archive (HSA) are unpublished. This is in largest part due to the limitations of the automated pipeline, and the complexities of interactive treatment the data to bring them to science-ready quality. New users of the archive lacking knowledge of the nuances of heterodyne instrumentation and/or experience with the data processing system are particularly challenged to optimize the data around their science interests or goals with ultra-high resolution spectra. Similarly, the effort to remove quality-degrading instrument artifacts and apply noise performance enhancements is a challenge at this stage even for more experienced users and original program observers who have not yet exploited their observations, either in part or in full as many published observations may also be further harvested for new science results. Recognizing that this situation will likely not improve over time, the HIFI instrument team put substantial effort during the funded post-cryo phase into interactively creating Highly Processed Data Products (HPDPs) from a set of observations in need of corrections and enhancements, in order to promote user accessibility and HIFI's scientific legacy. A set HPDPs created from 350 spectral mapping observations were created in an effort lead at the NASA Herschel Science Center, and delivered in November 2016 to the NASA InfraRed Science Archive (IRSA) and the HSA where they are available to the community. Due to limited resources, this effort could not cover the full list of observations in need of interactive treatments. We are proposing to cover that final set observations (spectral maps and a selection of spectral scans and point observations) in a project spread over 2 years with 0.5 FTE funding, for a guaranteed set of phased deliverables produced with optimized quality at high efficiency using expert processing and delivery procedures already in place. This effort will tackle the quality-degrading artifacts which could not be corrected in the automatic pipeline -- and becoming more and more remote for potential users to correct on their own even with scripted guidance. The expectation is that the huge investments by the funding agencies, and the successful operations of the observatory meeting and often exceeding performance requirements, can be returned to the maximum scientific extent possible. We can guarantee some of that scientific return, in a study of fundamental carbon chemistry in energetic star forming regions, using the proposed HPDPs from unpublished and partially unexploited HIFI data to probe UV- and shockdriven chemistries to explain an unexpected deficiency of C+ in the Orion KL eruptive outflow. We will test a hypothesis that C+ is depleted by production of CO rather than CH+, through a chain of reactions involving intermediate products suited to the molecular environment.

Emerging technology: A key enabler for modernizing pharmaceutical manufacturing and advancing product quality.

PubMed

O'Connor, Thomas F; Yu, Lawrence X; Lee, Sau L

2016-07-25

Issues in product quality have produced recalls and caused drug shortages in United States (U.S.) in the past few years. These quality issues were often due to outdated manufacturing technologies and equipment as well as lack of an effective quality management system. To ensure consistent supply of safe, effective and high-quality drug products available to the patients, the U.S. Food and Drug Administration (FDA) supports modernizing pharmaceutical manufacturing for improvements in product quality. Specifically, five new initiatives are proposed here to achieve this goal. They include: (i) advancing regulatory science for pharmaceutical manufacturing; (ii) establishing a public-private institute for pharmaceutical manufacturing innovation; (iii) creating incentives for investment in the technological upgrade of manufacturing processes and facilities; (iv) leveraging external expertise for regulatory quality assessment of emerging technologies; and (v) promoting the international harmonization of approaches for expediting the global adoption of emerging technologies.

Why Study Geoscience? Identifying Effective Recruitment and Retention Strategies for an Undergraduate Earth & Environmental Sciences Program

NASA Astrophysics Data System (ADS)

Vajoczki, S.; Eyles, C. H.; Stewart, J.; Dasilva, L.

2005-12-01

McMaster University is a `research intensive' university with 17,000+ full time undergraduate students. The School of Geography and Earth Sciences (SGES) is located within the Faculty of Science, offers B.Sc., B.A., M.Sc., M.A. and PhD degree programs and teaches more than 70 undergraduate courses on an annual basis. The Honours B.Sc program in Earth and Environmental Sciences (EES) graduates approximately 25 students per year. Students enroll in undergraduate SGES programs in their second year, after completion of an introductory first year in the Faculty of Science in which they take compulsory science courses including math, physics, chemistry, and biology. First year students, as well as those in upper years, may also elect to take one or more of three introductory courses offered by SGES (Earth & the Environment, The Living Environment, Atmosphere & Hydrosphere) to complete their science requirements. Most students entering the Faculty of Science know little about geoscience as it does not form an important part of the Ontario secondary school curriculum. Hence, recruitment into the EES program is primarily via the first year courses. In order to establish reasons why students elected to take the introductory courses offered by SGES, and their reasons for considering subsequent entry to the B.Sc program, a survey of students taking one of the courses was conducted in the fall of 2003. Results from the survey indicate that students enroll in the course, and subsequently the EES program, for a variety of reasons including: general interest in how the planet works, concern for the environment, interesting title of the course and reputation of the instructor. Student concern over lack of potential jobs is cited as the main reason for not pursuing a degree in geoscience. This survey has helped to direct the multifaceted recruitment strategies used by SGES to continue to develop its undergraduate program through delivery of high quality first year courses. Additional recruitment strategies used to recruit and retain high quality students include an active undergraduate society and departmental events that contribute towards a culture of learning and sense of belonging that is sought by students.

Getting from Here to There: The Roles of Policy Makers and Principals in Increasing Science Teacher Quality

Shen, Ji; Gerard, Libby; Bowyer, Jane

2010-04-01

In this study we investigate how federal and state policy makers, and school principals are working to improve science teacher quality. Interviews, focused discussions, and policy documents serve as the primary data source. Findings suggest that both policy makers and principals prioritize increasing incentives for teachers entering the science teaching profession, providing professional development for new teachers, and using students’ data to evaluate and improve instruction. Differences between the two leadership groups emerged in terms of the grain size and practicality of their concerns. Our findings indicate that the complexity of educational challenges to improve science teacher quality call for the co-construction of policy by multiple constituent groups including school principals, federal and state policy makers, and science education researchers.

This pilot study investigates the impact of a 2-week professional development Summer Institute on PK-3 teachers' knowledge and practices. This Summer Institute is a component of [program], a large-scale early-childhood science project that aims to transform PK-3 science teaching. The mixed-methods study examined concept maps, lesson plans, and classroom observations to measure possible changes in PK-3 teachers' science content knowledge and classroom practice from 11 teachers who attended the 2014 Summer Institute. Analysis of the concept maps demonstrated statistically significant growth in teachers' science content knowledge. Analysis of teachers' lesson plans demonstrated that the teachers could design high quality science inquiry lessons aligned to the Next Generation Science Standards following the professional development. Finally, examination of teachers' pre- and post-Summer Institute videotaped inquiry lessons showed evidence that teachers were incorporating new inquiry practices into their teaching, especially regarding classroom discourse. Our results suggest that an immersive inquiry experience is effective at beginning a shift towards reform-aligned science and engineering instruction but that early elementary educators require additional support for full mastery.

The assembled teams were innovative and unique. This new model of development and production included a process that integrated all needed knowledge and expertise for the development of high quality science and math games for K-12 students. This new model has potential to be used by others for the development of the educational games. The uniqueness of the model is to integrate domain experts’ knowledge with researchers/quality control group, and combine a professional development team from the game development company with the academic game development team from Computer Science and Art departments at Ball State University. The developed games went through feasibility tests with selected students for improvement before use in the research activities.« less

Science Education Supporting Weather Broadcasters On-Air and in the Classroom with NASA "Mini-Education Supplements"

NASA Technical Reports Server (NTRS)

Shepherd, J. Marshall; Starr, David OC. (Technical Monitor)

2001-01-01

NASA-Goddard Space Flight Center has initiated a new project designed to expand on existing news services and add value to classrooms through the development and distribution of two-minute 'mini-supplements' which give context and teach about current weather and Earth research phenomena. The innovative mini-supplements provide raw materials for weather forecasters to build news stories around NASA related missions without having to edit the more traditional and cumbersome long-form video format. The supplements cover different weather and climate topics and include NASA data, animations, video footage, and interviews with scientists. The supplements also include a curriculum package with educational lessons, educator guide, and hand-on activities. One goal is to give on-air broadcasters who are the primary science educators for the general public what they need to 'teach' about the science related to NASA research behind weather and climate news. This goal achieves increasing public literacy and assures higher accuracy and quality science reporting by the media. The other goal is to enable on-air broadcasters to serve as distributors of high quality, standards-based educational curricula and supplemental material when they visit 8-12 grade classrooms. The focus of 'pilot effort' centers around the success of NASA's Tropical Rainfall Measuring Mission (TRMM) but is likely expandable to other NASA earth or space science missions.

Atmospheric absorption, scattering, and scintillation are the major causes to deteriorate the transmission quality of terahertz (THz) wireless communications. An error control coding scheme based on low density parity check (LDPC) codes with soft decision decoding algorithm is proposed to improve the bit-error-rate (BER) performance of an on-off keying (OOK) modulated THz signal through atmospheric channel. The THz wave propagation characteristics and channel model in atmosphere is set up. Numerical simulations validate the great performance of LDPC codes against the atmospheric fading and demonstrate the huge potential in future ultra-high speed beyond Gbps THz communications.

Citizen Science is a fast-growing ecological research tool with proven potential to rapidly produce large datasets. While the fields of astronomy and ornithology demonstrate particularly successful histories of enlisting the public in conducting scientific work, citizen science applications to the field of hydrology have been relatively underutilized. We demonstrate the potential of citizen science for monitoring water quality, particularly in the impervious, urban environment of New York City (NYC) where pollution via stormwater runoff is a leading source of waterway contamination. Through partnerships with HSBC, Earthwatch, and the NYC Water Trail Association, we have trained two citizen science communities to monitor the quality of NYC waterways, testing for a suite of water quality parameters including pH, turbidity, phosphate, nitrate, and Enterococci (an indicator bacteria for the presence of harmful pathogens associated with fecal pollution). We continue to enhance these citizen science programs with two additions to our methodology. First, we designed and produced at-home incubation ovens for Enterococci analysis, and second, we are developing automated photo-imaging for nitrate and phosphate concentrations. These improvements make our work more publicly accessible while maintaining scientific accuracy. We also initiated a volunteer survey assessing the motivations for participation among our citizen scientists. These three endeavors will inform future applications of citizen science for urban hydrological research. Ultimately, the spatiotemporally-rich dataset of waterway quality produced from our citizen science efforts will help advise NYC policy makers about the impacts of green infrastructure and other types of government-led efforts to clean up NYC waterways.

A novel polishing technology for epoxy resin based on 355 nm UV laser

2017-06-01

The electromagnetic shielding film has drawn much attention due to its wide applications in the integrated circuit package, which demands a high surface quality of epoxy resin. However, gaseous Cu will splash and adhere to epoxy resin surface when the Cu layer in PCB receives enough energy in the process of laser cutting, which has a negative effect on the quality of the shielding film. Laser polishing technology can solve this problem and it can effectively improve the quality of epoxy resin surface. The paper studies the mechanism of Cu powder spraying on the compound surface by 355 nm ultraviolet (UV) laser, including the parameters of laser polishing process and the remains of Cu content on compound surface. The results show that minimal Cu content can be realized with a scanning speed of 700 mm/s, a laser frequency of 50 kHz and the distance between laser focus and product top surface of -1.3 mm. This result is important to obtain an epoxy resin surface with high quality.

An important objective of the High Speed Research Program (HSRP) is to support research in the atmospheric sciences that will improve the basic understanding of the circulation and chemistry of the stratosphere and lead to an interim assessment of the impact of a projected fleet of High Speed Civil Transports (HSCT's) on the stratosphere. As part of this work, critical comparisons between models and existing high quality measurements are planned. These comparisons will be used to test the reliability of current atmospheric chemistry models. Two suitable sets of high resolution infrared measurements are discussed.

The influence of a train-the-trainer professional development on teacher perceptions of science integration and inquiry-based instruction

NASA Astrophysics Data System (ADS)

Blythe, Jessica Marie

The purpose of this study was to describe the influence of the train-the-trainer professional development form of professional development on participants' perceptions of agriscience integration and inquiry-based instruction (IBI). The independent variables considered were elements of high-quality professional development, such as duration, active participation, coherence, and school culture; teacher attitudes towards professional development; and teacher demographics. The dependent variables assessed were teachers' perceptions of agriscience integration and IBI. This study utilized a quasi-experimental design to assess the impacts of a teacher professional development program and experimental follow-up support on secondary teachers' perceptions of science integration and IBI. This study was a census of all teachers who attended a 2012 professional development workshop facilitated by a National Agriscience Teacher Ambassador at the FFA and/or NAAE National Convention. Participants completed four surveys over the subsequent year to assess their perceptions of agriscience integration and IBI. Descriptive methods were used to analyze teachers' perceptions of agriscience integration and IBI. Correlations and follow-up regression analysis were conducted to determine the relationships between the teachers' perceptions and the elements of high-quality teacher professional development. Results of the study revealed that respondents had favorable perceptions of science integration into agriculture programs and planned to increase the levels of science integration in their programs. Additionally, a majority of respondents reported utilizing IBI more than once a week. Because participants of the study did not utilize the experimental follow-up support system for the workshop, clear effects could not be determined. There was a positive correlation between science integration and IBI. A variation of positive and negative correlations was found between the dependent and independent variables. Five models were found to be significant predictors of respondents' perceptions of science integration three models were found to be significant predictors of IBI. These findings indicate that teachers perceive science integration and IBI as positive influences in secondary agriculture education which supports the integration of science and science teaching techniques in secondary agriculture education programs. Though relationships exist between science integration and IBI, and various elements of school culture and professional development, further investigation is needed to better understand these relationships and their predictive variability.

Air quality and climate--synergies and trade-offs.

PubMed

von Schneidemesser, Erika; Monks, Paul S

2013-07-01

Air quality and climate are often treated as separate science and policy areas. Air quality encompasses the here-and-now of pollutant emissions, atmospheric transformations and their direct effect on human and ecosystem health. Climate change deals with the drivers leading to a warmer world and the consequences of that. These two science and policy issues are inexorably linked via common pollutants, such as ozone (methane) and black carbon. This short review looks at the new scientific evidence around so-called "short-lived climate forcers" and the growing realisation that a way to meet short-term climate change targets may be through the control of "air quality" pollutants. None of the options discussed here can replace reduction of long-lived greenhouse gases, such as CO2, which is required for any long-term climate change mitigation strategy. An overview is given of the underlying science, remaining uncertainties, and some of the synergies and trade-offs for addressing air quality and climate in the science and policy context.

Strategy for earth explorers in global earth sciences

NASA Technical Reports Server (NTRS)

1988-01-01

The goal of the current NASA Earth System Science initiative is to obtain a comprehensive scientific understanding of the Earth as an integrated, dynamic system. The centerpiece of the Earth System Science initiative will be a set of instruments carried on polar orbiting platforms under the Earth Observing System program. An Earth Explorer program can open new vistas in the earth sciences, encourage innovation, and solve critical scientific problems. Specific missions must be rigorously shaped by the demands and opportunities of high quality science and must complement the Earth Observing System and the Mission to Planet Earth. The committee believes that the proposed Earth Explorer program provides a substantial opportunity for progress in the earth sciences, both through independent missions and through missions designed to complement the large scale platforms and international research programs that represent important national commitments. The strategy presented is intended to help ensure the success of the Earth Explorer program as a vital stimulant to the study of the planet.

Accuracy of sign interpreting and real-time captioning of science videos for the delivery of instruction to deaf students

NASA Astrophysics Data System (ADS)

Sadler, Karen L.

2009-04-01

The purpose of this study was to quantitatively examine the impact of third-party support service providers on the quality of science information available to deaf students in regular science classrooms. Three different videotapes that were developed by NASA for high school science classrooms were selected for the study, allowing for different concepts and vocabulary to be examined. The focus was on the accuracy of translation as measured by the number of key science words included in the transcripts (captions) or videos (interpreted). Data were collected via transcripts completed by CART (computer assisted real-time captionists) or through videos of sign language interpreters. All participants were required to listen to and translate these NASA educational videos with no prior experience with this information so as not to influence their delivery. CART personnel using captions were found to be significantly more accurate in the delivery of science words as compared to the sign language interpreters in this study.

Urban science education: examining current issues through a historical lens

NASA Astrophysics Data System (ADS)

McLaughlin, Cheryl A.

2014-12-01

This paper reviews and synthesizes urban science education studies published between 2000 and 2013 with a view to identifying current challenges faced by both teachers and students in urban classrooms. Additionally, this paper considers the historical events that have shaped the conditions, bureaucracies, and interactions of urban institutions. When the findings from these urban science education studies were consolidated with the historical overview provided, it was revealed that the basic design and regulatory policies of urban schools have not substantively changed since their establishment in the nineteenth century. Teachers in urban science classrooms continue to face issues of inequality, poverty, and social injustice as they struggle to meet the needs of an increasingly diverse student population. Furthermore, persistent concerns of conflicting Discourses, cultural dissonance, and oppression create formidable barriers to science learning. Despite the many modifications in structure and organization, urban students are still subjugated and marginalized in systems that emphasize control and order over high-quality science education.

Environmental benefits of biochar.

Ippolito, James A; Laird, David A; Busscher, Warren J

2012-01-01

Understanding and improving environmental quality by reducing soil nutrient leaching losses, reducing bioavailability of environmental contaminants, sequestering C, reducing greenhouse gas emissions, and enhancing crop productivity in highly weathered or degraded soils, has been the goal of agroecosystem researchers and producers for years. Biochar, produced by pyrolysis of biomass, may help attain these goals. The desire to advance understanding of the environmental and agronomic implication of biochar utilization led to the organization of the 2010 American Society of Agronomy-Soil Science Society of America Environmental Quality Division session titled "Biochar Effects on the Environment and Agricultural Productivity." This specialized session and sessions from other biochar conferences, such as the 2010 U.S. Biochar Initiative and the Biochar Symposium 2010 are the sources for this special manuscript collection. Individual contributions address improvement of the biochar knowledge base, current information gaps, and future biochar research needs. The prospect of biochar utilization is promising, as biochars may be customized for specific environmental applications.

2017-12-01

Few studies have examined the sources of practice knowledge fitness trainers use to inform their training methods and update knowledge. This study aims to describe sources of practice knowledge among Australian fitness trainers. In July 2014, 9100 Australian fitness trainers were invited to complete an online survey. Respondents reported the frequency of use of eight sources of practice knowledge (e.g. fitness magazines, academic texts). In a separate survey, exercise science experts (n = 27) ranked each source as either (1) 'high-quality' or (2) 'low-quality'. Proportions of users of 'high-quality' sources were calculated across demographic (age, sex) and fitness industry-related characteristics (qualification, setting, role). A multivariate logistic regression analysis assessed the odds of being classified as a user of high-quality sources, adjusting for demographic and fitness industry-related factors. Out of 1185 fitness trainers (response rate = 13.0%), aged 17-72 years, 47.6% (95% CI, 44.7-50.4%) were classified as frequent users of high-quality sources of practice knowledge. In the adjusted analysis, compared to trainers aged 17-26 years, those aged ≥61 years (OR, 2.15; 95% CI, 1.05-4.38) and 40-50 years (OR, 1.54; 95% CI, 1.02-2.31) were more likely to be classified as a user of high-quality sources. When compared to trainers working in large centres, those working in outdoor settings (OR, 1.81; 95% CI, 1.23-2.65) and medium centres (OR, 1.59; 95% CI, 1.12-2.29) were more likely to be classified as users of high-quality sources. Our findings suggest that efforts should be made to improve the quality of knowledge acquisition among Australian fitness trainers.

A comparison of Massachusetts and Texas high school biology teachers' attitudes towards the teaching of evolution

NASA Astrophysics Data System (ADS)

Howarth, Richard T.

Darwin's theory of evolution by natural selection is considered to be the unifying theory for all life sciences (American Association for the Advancement of Science, AAAS, 1990; National Academy of Sciences, 1998; National Research Council, NRC, 1996; National Science Teachers Association, NSTA, 2010a) and as such, the biology topic has been established as a central learning standard by the National Science Education Science Standards (NSES, 2005). The purpose of this study was to compare how Massachusetts and Texas high school biology teachers' attitudes toward the teaching of evolution differ as compared to other biology topics. Texas and Massachusetts are two states that exemplify standards based education yet differ dramatically in their histories surrounding the topic of evolution. A survey was conducted among 217 Massachusetts and 139 Texas in-service high school biology teachers to help provide a sense of the phenomena surrounding biology teachers in respect to how their attitudes towards the teaching of evolution are shaped. Additionally, an open-ended question was asked to help contextualize the results of the survey between teachers of these two states. The findings in this study suggest that community appears to be a powerful persuasive message and socialization experience that shapes the development of attitudes towards evolution for some educators, especially when it is highly intertwined with religion. For biology teachers in the state of Texas, the synergistic result of this relationship has resulted in statistically significant differences in regards to attitudes towards evolution as compared to teachers in Massachusetts. These findings yield implications regarding scientific literacy, student learning, assessment, the quality of science instruction, curriculum, undergraduate biology programs, and the needs of biology teachers in terms of professional development.

Do science coaches promote inquiry-based instruction in the elementary science classroom?

NASA Astrophysics Data System (ADS)

Wicker, Rosemary Knight

The South Carolina Mathematics and Science Coaching Initiative established a school-based science coaching model that was effective in improving instruction by increasing the level of inquiry-based instruction in elementary science classrooms. Classroom learning environment data from both teacher groups indicated considerable differences in the quality of inquiry instruction for those classrooms of teachers supported by a science coach. All essential features of inquiry were demonstrated more frequently and at a higher level of open-ended inquiry in classrooms with the support of a science coach than were demonstrated in classrooms without a science coach. However, from teacher observations and interviews, it was determined that elementary schoolteacher practice of having students evaluate conclusions and connect them to current scientific knowledge was often neglected. Teachers with support of a science coach reported changes in inquiry-based instruction that were statistically significant. This mixed ethnographic study also suggested that the Mathematics and Science Coaching Initiative Theory of Action for Instructional Improvement was an effective model when examining the work of science coaches. All components of effective school infrastructure were positively impacted by a variety of science coaching strategies intended to promote inquiry. Professional development for competent teachers, implementation of researched-based curriculum, and instructional materials support were areas highly impacted by the work of science coaches.

Globally, sustainable provision of high-quality safe water is a major challenge of the 21st century. Various chemical and biological monitoring analytics are presently utilized to guarantee the availability of high-quality water. However, these techniques still face some challenges including high costs, complex design and onsite and online limitations. The recent technology of using microbial fuel cell (MFC)-based biosensors holds outstanding potential for the rapid and real-time monitoring of water source quality. MFCs have the advantages of simplicity in design and efficiency for onsite sensing. Even though some sensing applications of MFCs were previously studied, e.g. biochemical oxygen demand sensor, recently numerous research groups around the world have presented new practical applications of this technique, which combine multidisciplinary scientific knowledge in materials science, microbiology and electrochemistry fields. This review presents the most updated research on the utilization of MFCs as potential biosensors for monitoring water quality and considers the range of potentially toxic analytes that have so far been detected using this methodology. The advantages of MFCs over established technology are also considered as well as future work required to establish their routine use. © 2017 The Society for Applied Microbiology.

Summary Organ transplantation has developed over the past 50 years to reach the sophisticated and integrated clinical service of today through several advances in science. One of the most important of these has been the ability to apply organ preservation protocols to deliver donor organs of high quality, via a network of organ exchange to match the most suitable recipient patient to the best available organ, capable of rapid resumption of life-sustaining function in the recipient patient. This has only been possible by amassing a good understanding of the potential effects of hypoxic injury on donated organs, and how to prevent these by applying organ preservation. This review sets out the history of organ preservation, how applications of hypothermia have become central to the process, and what the current status is for the range of solid organs commonly transplanted. The science of organ preservation is constantly being updated with new knowledge and ideas, and the review also discusses what innovations are coming close to clinical reality to meet the growing demands for high quality organs in transplantation over the next few years.

2013-10-01

Desert Research and Technology Studies (Desert RATS) is a multi-year series of hardware and operations tests carried out annually in the high desert of Arizona on the San Francisco Volcanic Field. These activities are designed to exercise planetary surface hardware and operations in conditions where long-distance, multi-day roving is achievable, and they allow NASA to evaluate different mission concepts and approaches in an environment less costly and more forgiving than space. The results from the RATS tests allow selection of potential operational approaches to planetary surface exploration prior to making commitments to specific flight and mission hardware development. In previous RATS operations, the Science Support Room has operated largely in an advisory role, an approach that was driven by the need to provide a loose science mission framework that would underpin the engineering tests. However, the extensive nature of the traverse operations for 2010 expanded the role of the science operations and tested specific operational approaches. Science mission operations approaches from the Apollo and Mars-Phoenix missions were merged to become the baseline for this test. Six days of traverse operations were conducted during each week of the 2-week test, with three traverse days each week conducted with voice and data communications continuously available, and three traverse days conducted with only two 1-hour communications periods per day. Within this framework, the team evaluated integrated science operations management using real-time, tactical science operations to oversee daily crew activities, and strategic level evaluations of science data and daily traverse results during a post-traverse planning shift. During continuous communications, both tactical and strategic teams were employed. On days when communications were reduced to only two communications periods per day, only a strategic team was employed. The Science Operations Team found that, if communications are good and down-linking of science data is ensured, high quality science returns is possible regardless of communications. What is absent from reduced communications is the scientific interaction between the crew on the planet and the scientists on the ground. These scientific interactions were a critical part of the science process and significantly improved mission science return over reduced communications conditions. The test also showed that the quality of science return is not measurable by simple numerical quantities but is, in fact, based on strongly non-quantifiable factors, such as the interactions between the crew and the Science Operations Teams. Although the metric evaluation data suggested some trends, there was not sufficient granularity in the data or specificity in the metrics to allow those trends to be understood on numerical data alone.

2012-01-01

Planetary surface exploration missions present considerable operational challenges in the form of substantial communication delays, limited communication windows, and limited communication bandwidth. A 3D visualization software was developed and delivered to the 2008 Phoenix Mars Lander (PML) mission. The components of the system include an interactive 3D visualization environment called Mercator, terrain reconstruction software called the Ames Stereo Pipeline, and a server providing distributed access to terrain models. The software was successfully utilized during the mission for science analysis, site understanding, and science operations activity planning. A terrain server was implemented that provided distribution of terrain models from a central repository to clients running the Mercator software. The Ames Stereo Pipeline generates accurate, high-resolution, texture-mapped, 3D terrain models from stereo image pairs. These terrain models can then be visualized within the Mercator environment. The central cross-cutting goal for these tools is to provide an easy-to-use, high-quality, full-featured visualization environment that enhances the mission science team s ability to develop low-risk productive science activity plans. In addition, for the Mercator and Viz visualization environments, extensibility and adaptability to different missions and application areas are key design goals.

Fluids and Materials Science Studies Utilizing the Microgravity-vibration Isolation Mount (MIM)

Herring, Rodney; Tryggvason, Bjarni; Duval, Walter

1998-01-01

Canada's Microgravity Sciences Program (MSP) is the smallest program of the ISS partners and so can participate in only a few, highly focused projects in order to make a scientific and technological impact. One focused project involves determining the effect of accelerations (g-jitter) on scientific measurements in a microgravity environment utilizing the Microgravity-vibration Isolation Mount (MIM). Many experiments share the common characteristic of having a fluid stage in their process. The quality of the experimental measurements have been expected to be affected by g-jitters which has lead the ISS program to include specifications to limit the level of acceleration allowed on a subset of experimental racks. From finite element analysis (FEM), the ISS structure will not be able to meet the acceleration specifications. Therefore, isolation systems are necessary. Fluid science results and materials science results show significant sensitivity to g-jitter. The work done to date should be viewed only as a first look at the issue of g-jitter sensitivity. The work should continue with high priority such that the international science community and the ISS program can address the requirement and settle on an agreed to overall approach as soon as possible.

Here I outline some of what science can tell us about the problems in psychological publishing and how to best address those problems. First, the motivation behind questionable research practices is examined (the desire to get ahead or, at least, not fall behind). Next, behavior modification strategies are discussed, pointing out that reward works better than punishment. Humans are utility seekers and the implementation of current change initiatives is hindered by high initial buy-in costs and insufficient expected utility. Open science tools interested in improving science should team up, to increase utility while lowering the cost and risk associated with engagement. The best way to realign individual and group motives will probably be to create one, centralized, easy to use, platform, with a profile, a feed of targeted science stories based upon previous system interaction, a sophisticated (public) discussion section, and impact metrics which use the associated data. These measures encourage high quality review and other prosocial activities while inhibiting self-serving behavior. Some advantages of centrally digitizing communications are outlined, including ways the data could be used to improve the peer review process. Most generally, it seems that decisions about change design and implementation should be theory and data driven.

A phenomenological analysis of the essence of the science education experience as perceived by female high school physics and advanced chemistry students

Papadimitriou, Michael

The purpose of this phenomenological study was to describe the essential elements of the current science education experience as constructed by twelve female high school physics and advanced chemistry students. The expressed desired outcome was a description of the phenomenon from a participant point of view. Student recollections and interpretations of experiences were assessed for a twelve-week period. Data sources were student journals, autobiographies, interviews, focus group interviews and researcher observations. In addition, each participant completed the Test of Science Related Attitudes (Fraser, 1981) in order to create attitude profiles for triangulation with other data. While a wide range of aspects of the science education experience emerged, results showed that female students describe and interpret their science education experiences on the basis of actual interest in science, early science experiences, perception of ability, self-confidence, teacher attributes, parental and peer interaction, societal expectations, the nature of science, and gender. Of these factors, specifically, interest and curiosity, societal influence, the nature of science, lack of in-school experiences, the desire to help others, and general parent support were most impacting upon experience and the desire to continue science study. Moreover, the interaction of these factors is relevant. Very simply, early experiences are crucial to interest development. In general, parents can enhance this interest by providing science-related experiences. In the absence of early in-school experiences (i.e., which the participants reported), these out-of-school experiences become crucial. More importantly, quality instruction and parent and peer support are needed to foster science interest and to overcome the powerfully negative influence of society, the discriminatory nature of science, and the lack of experiences.

An Improved Forensic Science Information Search.

Teitelbaum, J

2015-01-01

Although thousands of search engines and databases are available online, finding answers to specific forensic science questions can be a challenge even to experienced Internet users. Because there is no central repository for forensic science information, and because of the sheer number of disciplines under the forensic science umbrella, forensic scientists are often unable to locate material that is relevant to their needs. The author contends that using six publicly accessible search engines and databases can produce high-quality search results. The six resources are Google, PubMed, Google Scholar, Google Books, WorldCat, and the National Criminal Justice Reference Service. Carefully selected keywords and keyword combinations, designating a keyword phrase so that the search engine will search on the phrase and not individual keywords, and prompting search engines to retrieve PDF files are among the techniques discussed.

The term big data is currently a buzzword in social science, however its precise meaning is ambiguous. In this paper we focus on administrative data which is a distinctive form of big data. Exciting new opportunities for social science research will be afforded by new administrative data resources, but these are currently under appreciated by the research community. The central aim of this paper is to discuss the challenges associated with administrative data. We emphasise that it is critical for researchers to carefully consider how administrative data has been produced. We conclude that administrative datasets have the potential to contribute to the development of high-quality and impactful social science research, and should not be overlooked in the emerging field of big data.

The purpose of the CAS workshop is to bring together NASA's scientists and engineers and their counterparts in industry, other government agencies, and academia working in the Computational Aerosciences and related fields. This workshop is part of the technology transfer plan of the NASA High Performance Computing and Communications (HPCC) Program. Specific objectives of the CAS workshop are to: (1) communicate the goals and objectives of HPCC and CAS, (2) promote and disseminate CAS technology within the appropriate technical communities, including NASA, industry, academia, and other government labs, (3) help promote synergy among CAS and other HPCC scientists, and (4) permit feedback from peer researchers on issues facing High Performance Computing in general and the CAS project in particular. This year we had a number of exciting presentations in the traditional aeronautics, aerospace sciences, and high-end computing areas and in the less familiar (to many of us affiliated with CAS) earth science, space science, and revolutionary computing areas. Presentations of more than 40 high quality papers were organized into ten sessions and presented over the three-day workshop. The proceedings are organized here for easy access: by author, title and topic.
