    Smith, Vivian Lee

    Science fairs have a long history in American education. They play an important role for establishing inquiry-based experiences in a science classroom. Students may be more motivated to learn science content when they are allowed to choose their own science fair topics. The purpose of this study was to examine Deaf college students' perceptions and experiences regarding science fair participation during primary and/or secondary school and determine the influence of science fair involvement on the development of language skills, writing skills, and higher order thinking skills as well as its impact on choice of a STEM major. This study examined responses from Deaf students attending Gallaudet University and National Technical Institute for the Deaf (NTID) majoring in a Science, Technology, Engineering, or Math (STEM) field. An electronic questionnaire and a semi-structured interview were used to collect data. The electronic questionnaire was divided into two strands: demographics and science fair experience. Twenty-one respondents participated in the questionnaire and ten participants were interviewed. A cross-case analysis revealed communication was the key to a successful science fair experience. Findings showed the educational background of participants influenced their perspective regarding the experience of a science fair. When communicating through American Sign Language, the science fair experience was more positive. When communicating through an interpreter or having no interpreter at all, the science fair experience was viewed in a negative light. The use of science fairs to enhance language development, writing skills, and higher order thinking skills was supported. Teachers and parents were strong influences for Deaf students participating in a science fair. Participation in a science fair did influence students to choose a STEM major but there were other considerations as well.

    Research misconduct has become an important matter of concern in the scientific community. The extent to which such behavior occurs early in science education has received little attention. In the current study, using the web-based data collection program REDCap, we obtained responses to an anonymous and voluntary survey about science fair from 65 high school students who recently competed in the Dallas Regional Science and Engineering Fair and from 237 STEM-track, post-high school students (undergraduates, 1st year medical students, and 1st year biomedical graduate students) doing research at UT Southwestern Medical Center. Of the post-high school students, 24% had competed in science fair during their high school education. Science fair experience was similar overall for the local cohort of Dallas regional students and the more diverse state/national cohort of post-high school students. Only one student out of 122 reported research misconduct, in his case making up the data. Unexpectedly, post-high school students who did not participate in science fair anticipated that carrying out science fair would be much more difficult than actually was the case, and 22% of the post-high school students anticipated that science fair participants would resort to research misconduct to overcome obstacles. No gender-based differences between students’ science fair experiences or expectations were evident. PMID:28328976

    Finnerty, Valerie

    The purpose of this study was to investigate whether participation in a school-based science fair affects middle school students' attitudes toward science and interest in science and engineering careers. A quasi-experimental design was used to compare students' pre- and posttest attitudes toward and interest in science. Forty-eight of the 258 participants completed a school-based science fair during the study. In addition, twelve middle school science teachers completed an online survey. Both the Survey of Science Attitudes and Interest I and II (SSAI-I and II) measured students' attitudes toward and interest in science and science and mathematics self-efficacy, asked about classroom inquiry experiences and gathered demographic information. An online survey gathered qualitative data about science teachers' perceptions of school science fairs. The results showed no significant interactions among completion of a science fair project and attitudes toward and interest in science, science and mathematics self-efficacy or gender. There were significant differences at both pre- and posttest in attitudes between the students who did and did not complete a science fair project. All participating teachers believed that participation in science fairs could have a positive effect on students' attitudes and interest, but cited lack of time as a major impediment. There was significant interaction between level of classroom inquiry and attitudes and interest in science; students who reported more experiences had higher scores on these measures. Classroom inquiry also interacted with the effects of a science fair and participants' pre- and posttest attitude scores. Finally, the amount and source of assistance on a science fair project had a significant impact on students' posttest measures. Major limitations which affect the generalization of these findings include the timing of the administration of the pretest, the number of participants in the experimental group and differences

  7. Investigating Teachers' Beliefs in the Implementation of Science Inquiry and Science Fair in Three Boston High Schools

    NASA Astrophysics Data System (ADS)

    De Barros Miller, Anne Marie

    In previous decades, inquiry has been the focus of science education reform in the United States. This study sought to investigate how teachers' beliefs affect their implementation of inquiry science and science fair. It was hypothesized that science teachers' beliefs about inquiry science and science fair are predictive of their implementation of such strategies. A case study approach and semi-structured interviews were employed to collect the data, and an original thematic approach was created to analyze the data. Findings seem to suggest that science teachers who embrace science inquiry and science fair believe these practices enhance students' performance, facilitate their learning experience, and allow them to take ownership of their learning. However, results also suggest that teachers who do not fully embrace inquiry science as a central teaching strategy tend to believe that it is not aligned with standardized tests and requires higher cognitive skills from students. Overall, the study seems to indicate that when inquiry is presented as a prescribed teaching approach, this elicits strong negative feelings/attitudes amongst science teachers, leading them not only to resist inquiry as a teaching tool, but also dissuading them from participating in science fair. Additionally, the findings suggest that such feelings among teachers could place the school at risk of not implementing inquiry science and science fair. In conclusion, the study reveals that science inquiry and science fair should not be prescribed to teachers as a top-down, mandatory approach for teaching science. In addition, the findings suggest that adequate teacher training in content knowledge and pedagogy in science inquiry and science fair should be encouraged, as this could help build a culture of science inquiry and implementation amongst teachers. This should go hand-in-hand with offering mentoring to science teachers new to inquiry and science fair for 2-5 years.

  9. From science fair to project-based science: A study of the implementation of an innovation through an existing activity system

    NASA Astrophysics Data System (ADS)

    Walker, Lisa Jean

    The implementation process is critical to the success of educational innovations. Project-based science is an innovation designed to support students' science learning. Science fair is a pervasive school practice in which students exhibit science projects. Little is known about how science fair may affect the implementation of reform efforts in science education. This study explores the relationship of science fair and project-based science in the classrooms of three science teachers. Two theories are used to understand science fair as an instructional practice. Cultural historical activity theory supports an analysis of the origins and development of science fair. The idea of communities of practice supports a focus on why and how educational practitioners participate in science fair and what meanings the activity holds for them. The study identifies five historically-based design themes that have shaped science fair: general science, project method, scientific method, extra-curricular activity, and laboratory science. The themes provide a new framework for describing teachers' classroom practices for science fair activities and support analysis of the ways their practices incorporate aspects of project-based science. Three case studies in Chicago present ethnographic descriptions of science fair practices within the context of school communities. One focuses on the scientific method as a linear process for doing science, another on knowledge generation through laboratory experiments, and the third on student ability to engage in open-ended inquiry. One teacher reinvents a project-based science curriculum to strengthen students' laboratory-based science fair projects, while another reinvents science fair to teach science as inquiry. In each case, science fair is part of the school's efforts to improve science instruction. The cases suggest that reform efforts help to perpetuate science fair practice. To support systemic improvements in science education, this

  12. Development of an instrument to measure student attitudes toward science fairs

    NASA Astrophysics Data System (ADS)

    Huddleston, Claudia A.

    Science fairs are woven into the very fabric of science instruction in the United States and in other countries. Even though thousands of students participate in science fairs every year, no instrument to measure student attitudes toward partaking in this hands-on learning experience has been fully developed and available for school administrators and teachers to assess the perceived value that current students attribute to participation in science fairs. Therefore, the purpose of this study was to continue the development and refinement of an instrument that measured student attitudes towards science fairs based on an unpublished instrument created by Michael (2005). The instrument developed and tested using 110 students at two different middle schools in southwest Virginia. The instrument consisted of 45 questions. After applying a principal component factor analysis, the instrument was reduced to two domains, enjoyment and value. The internal consistency of the instrument was calculated using Cronbach's alpha and showed good internal consistency of .89 between the two domains. Further analysis was conducted using a Pearson product-moment test and showed a significant positive correlation between enjoyment and value (r = .78). Demographic information was explored concerning the domains using a series of statistical tests, and results revealed no significant differences among race and science fair category. However, a significant difference was found among gender and students who won awards and those who did not. The conclusion was that further development and refinement of the instrument should be conducted.

  17. The use of animals in national high school student science fair projects in the United States.

    PubMed

    Miller-Spiegel, Crystal

    2004-06-01

    Science fair projects can provide a sound opportunity to teach students the value of scientific methodology without relying on the routine and unnecessary use of animals. Unfortunately, students are often encouraged to use animals in an expendable manner that both duplicates previous experiments and neglects the opportunity to "think outside the box" in order to generate new hypotheses/theories about human health, physiological processes or basic biological concepts. Although at least one national science fair sponsor has changed its policy regarding students' utilisation of vertebrate animals, others continue to encourage the more traditional in vivo experimental projects. This paper will review the guidelines of two major national science fairs in the USA; types of projects conducted that involve animals; numbers of animals involved; interview responses by some student finalists who used vertebrates in their projects; successful initiatives by animal advocates in the USA to eliminate the use of animals in science fairs; and potential areas of outreach to science educators, science fair sponsors, high schools and students.

    For the past five years, the Coalition for Plasma Science (CPS) has presented an award for a plasma project at the Intel International Science and Engineering Fair (ISEF). Eligible projects have ranged from grape-based plasma production in a microwave oven to observation of the effects of viscosity in a fluid model of quark-gluon plasma. Most projects have been aimed at applications, including fusion, thrusters, lighting, materials processing, and GPS improvements. However diagnostics (spectroscopy), technology (magnets), and theory (quark-gluon plasmas) have also been represented. All of the CPS award-winning projects so far have been based on experiments, with two awards going to women students and three to men. Since the award was initiated, both the number and quality of plasma projects has increased. The CPS expects this trend to continue, and looks forward to continuing its work with students who are excited about the possibilities of plasma. You too can share this excitement by judging at the 2010 fair in San Jose on May 11-12.

That goal is outlined in a report entitled “Engage to excel,” by the President's Council of Advisors on Science and Technology (PCAST), released the same day. Obama also announced several other initiatives, including a $22 million private-sector investment, led by the Carnegie Corporation of New York, to invest in STEM teacher training. After he toured the science fair projects, Obama said the science fair students “inspire” him. “What impresses me so much is not just how smart you are, but it's the fact that you recognize you've got a responsibility to use your talents in service of something bigger than yourselves,” he said. What these young people are doing is “going to make a bigger difference in the life of our country over the long term than just about anything,” adding, “We've got to emphasize how important this is and recognize these incredible young people who are doing that that I couldn't even imagine thinking about at fifth grade or eighth grade or in high school.”

  4. Evaluation of constructivist pedagogy: Influence on critical thinking skills, science fair participation and level of performance

    NASA Astrophysics Data System (ADS)

    Foxx, Robbie Evelyn

    Science education reform, driven by a rapidly advancing technological society, demands the attention of both elementary and middle school curriculum-developers. Science education training in current standards (National Research Council [NRC] Standards 1996) emphasize inquiry, which is reported to be a basic tenet of the theory known as constructivism (NAASP, 1996; Cohen, 1988; Conley, 1993; Friedman, 1999; Newman, Marks, & Gamoran, 1996; Smerdon & Burkam 1999; Sizer 1992; Talbert & McLaughlin 1993; Tobin & Gallagher, 1987; Yager, 1991, 2000). Pedagogy focusing on the tenets of constructivist theory, at the intermediate level, can address current science standards. Many science educators believe participation in science fairs helps students develop the attitudes, skills, and knowledge that will help them to be comfortable and successful in the scientific and technological society (Czerniak, 1996). Competing in science fairs is one vehicle which allows students to apply science to societal issues, solve problems and model those things scientists do. Moreover, constructing a science fair project is suggested as being an excellent means to foster the development of concepts necessary in promoting scientific literacy (Czerniak, 1996). Research further suggests that through science fairs or other inquiry activities, students construct their knowledge with fewer misconceptions as they explore and discover the nature of science (NRC 1996). Tohn 's study (as cited in Bellipanni, 1994) stated that science fairs are a major campaign to increase student skills and to allow students a chance to have fun with science. The purpose of this research was twofold: (1) to assess science problem solving skills of students instructed using constructivist pedagogy, and (2) to explore the effects of constructivist pedagogy's influence(s) on science fair participation/placement. Students' attitudes resulting from these experiences were examined as well.

  5. Researching the Real: Transforming the Science Fair through Relevant and Authentic Research

    NASA Astrophysics Data System (ADS)

    Davidson, Rosemary McBryan

    This teacher research study documents the processes used to help students in an all-female, religious-based high school create science fair projects that are personally meaningful, scientifically sophisticated and up-to date in terms of science content. One-hundred sixteen young women in an honors chemistry class were introduced by their teacher to the methods used by science journalists when researching and crafting articles. The students then integrated these strategies into their science fair research through collaborative classroom activities designed by their teacher. Data collected during the process included audio and video tapes of classroom activities, student interviews, process work, finished projects, email conversations and the reflective journaling, annotated lesson plans, and memories of the lived experience by the teacher. The pedagogical changes which resulted from this project included the use of Read Aloud-Think Alouds (RATA) to introduce content and provide relevance, a discussion based topic selection process, the encouragement of relevant topic choices, the increased use of technology for learning activities and for sharing research, and an experimental design process driven by the student's personally relevant, topic choice. Built in feedback loops, provided by the teacher, peer editors and an outside editor, resulted in multiple revisions and expanded opportunities for communicating results to the community-at-large. Greater student engagement in science fair projects was evident: questioning for understanding, active involvement in decision making, collaboration within the classroom community, experience and expertise with reading, writing and the use of technology, sense of agency and interest in science related activities and careers all increased. Students communicated their evolving practices within the school community and became leaders who promoted the increased use of technology in all of their classes. Integrating journalistic

    The purpose of this 3 year project funded by NSF (GEO 1035049) is to increase the climate change science content knowledge and teaching effectiveness of in-service high school science teachers and increase the numbers of quality of high school geoscience projects competing in Nevada's three regional Intel ISEF (International Science & Engineering Fair) affiliated science fairs. In year 1 of the project participants consisted of six female and three male high school teachers from across Nevada. Eight of the participants were white and one was Asian. Five participants taught in Clark County, two taught in Owyhee, one taught in Elko and one taught in Spring Creek. Over 20% of the projects were noted (by the teachers) as being submitted by underrepresented students; however, this information is not reliable as most students did not provide this data themselves. Pre-and post- content tests were given. Teachers improved from an average of eight missed on the pre-test to an average of only four items missed on the post-test. Participants were also asked to evaluate their own teaching efficacy. In general, participants had a strong science efficacy. The item on which there was the most discrepancy among participants was on #10, the one stating that "The low achievement of some students cannot generally be blamed on their teachers." Most teachers completed an end of year program evaluation. All but one of the participants felt that the pace of the workshop was comfortable. All participants who used faculty mentors in helping their students rated their faculty mentors very highly. All participants rated the program content very highly in terms of clarity, organization, relevance, helpfulness and usefulness. All participants gave the program a very high rating overall and stated they would likely use the information to mentor future students and in instruction in future classes. The science fairs are the culmination of the program. Teachers were required to have at least one

    With the East Room of the White House flush with Nobel laureates and government officials, including freshly sworn-in U.S. National Science Foundation director Subra Suresh, President Barack Obama honored dozens of students who participated in a White House science fair on 18 October. The fair—many of whose participants have won other science, technology, engineering, and math (STEM) competitions—is part of a series of events that culminated 23-24 October in the USA Science and Engineering Festival on the National Mall in Washington, D. C., and at 50 satellite events around the country. “We welcome championship sports teams to the White House to celebrate their victories,” Obama said, noting that the Los Angeles Lakers basketball team, New Orleans Saints football team, and others have been to the White House. “I thought we ought to do the same thing for the winners of science fair and robotic contests and math competitions, because often we don’t give these victories the attention that they deserve. When you win first place at a science fair, nobody is rushing the field or dumping Gatorade over your head [in celebration].”

    Explicit racial bias has decreased in the United States, but racial stereotypes still exist and conspire in multiple ways to perpetuate the underparticipation of Blacks in science careers. Capitalizing on the potential effectiveness of role-playing video games to promote the type of active learning required to increase awareness of and reduce subtle racial bias, we developed the video game Fair Play, in which players take on the role of Jamal, a Black male graduate student in science, who experiences discrimination in his PhD program. We describe a mixed-methods evaluation of the experience of scientific workforce trainers who played Fair Play at the National Institutes of Health Division of Training Workforce Development and Diversity program directors’ meeting in 2013 (n = 47; 76% female, n = 34; 53% nonwhite, n = 26). The evaluation findings suggest that Fair Play can promote perspective taking and increase bias literacy, which are steps toward reducing racial bias and affording Blacks equal opportunities to excel in science.

    For the past eight years, the Coalition for Plasma Science (CPS) has presented an award for a plasma project at the Intel International Science and Engineering Fair (ISEF). We reported on the first five years of this award at the 2009 DPP Symposium. Pulsed neutron-producing experiments are a recurring topic, with the efforts now turning to applications. The most recent award at the Pittsburgh ISEF this past May was given for analysis of data from Brookhaven's Relativistic Heavy Ion Collider. The effort had the goal of understanding the fluid properties of the quark-gluon plasma. All of the CPS award-winning projects so far have been based on experiments, with four awards going to women students and four to men. In 2009 we noted that the number and quality of projects was improving. Since then, as we we predicted (hoped for), that trend has continued. The CPS looks forward to continuing its work with students who are excited about the possibilities of plasma. You too can share this excitement by judging at the 2013 fair in Phoenix on May 12-17.

    1994-01-01

    This manual is intended to act as a working guide for setting up a Science Fair Volunteer Support Committee at your school. The Science Fair Volunteer Support Committee, or SFVSC, is the key component of the Science Fair Self-Help program, which was developed by Sandia National Laboratories and is designed to support a school`s science activities. The SFVSC is a team of parents and community volunteers who work in concert with a school`s teaching staff to assist and manage all areas of a school Science and Engineering Fair. The main advantage of creating such a committee is that it freesmore » the science teachers from the organizational aspects of the fair and lets them concentrate on their job of teaching science. This manual is based on information gained through a Self-Help Development pilot program that was developed by Sandia National Laboratories during the 1991--92 school year at three Albuquerque, NM, middle schools. The manual describes the techniques that were successful in the pilot program and discusses how these techniques might be implemented in other schools.

  19. Gender-related attitudinal differences towards science fairs of students in Christian private schools in South Carolina

    NASA Astrophysics Data System (ADS)

    Westbury, Glenda F.

    Science fairs afford students at all grade levels the opportunity to practice thinking as a scientist does, a valuable 21st century skill (Jacobs, 2010) and may influence students to pursue STEM-related careers. Even though science fairs have been occurring since the 1920s, literature related to science competitions, especially science fairs, is limited (Dionne et al., 2012; Terzian, 2009). The purpose of this quantitative study was to use a causal comparative research design to determine if there is a difference in overall attitudes towards science fairs, enjoyment of science fairs, and usefulness of science fairs of female and male students at private Christian middle schools. The sample included 146 fifth through eighth grade students, 72 males and 74 females from four private Christian schools in the southern United States. The researcher visited each school and administered the Students' Attitudes toward Science Fairs (SATSFS) instrument (Michael & Huddleston, 2014) to the students on the day of the local science fair. A one-way multivariate analysis of variance (MANOVA) was used to determine the difference in attitudes between the female and male participants toward science fairs in the areas of overall attitude, student's enjoyment, and student's usefulness of science fairs. The result of the MANOVA was not significant at an alpha level of .05, where F (2, 143) = 2.52, p = .08, partial eta2 = 0.034, suggesting there are no significant differences on the dependent variables (enjoyment, usefulness, and overall attitude toward science fairs) by gender of fifth through eighth grade students in Christian private schools. The effect size as measured by partial eta squared was small. Implications for educators include the need to address gender differences in STEM education at earlier stages of development, and the importance of stressing personal meaning and relevance to science-related activities. Recommendations for further studies were made.

  3. Making science education meaningful for American Indian students: The effect of science fair participation

    NASA Astrophysics Data System (ADS)

    Welsh, Cynthia Ann

    Creating opportunities for all learners has not been common practice in the United States, especially when the history of Native American educational practice is examined (Bull, 2006; Chenoweth, 1999; Starnes, 2006a). The American Indian Science and Engineering Society (AISES) is an organization working to increase educational opportunity for American Indian students in science, engineering, and technology related fields (AISES, 2005). AISES provides pre-college support in science by promoting student science fair participation. The purpose of this qualitative research is to describe how American Indian student participation in science fairs and the relationship formed with their teacher affects academic achievement and the likelihood of continued education beyond high school. Two former American Indian students mentored by the principal investigator participated in this study. Four ethnographic research methods were incorporated: participant observation, ethnographic interviewing, search for artifacts, and auto-ethnographic researcher introspection (Eisenhart, 1988). After the interview transcripts, photos documenting past science fair participation, and researcher field notes were analyzed, patterns and themes emerged from the interviews that were supported in literature. American Indian academic success and life long learning are impacted by: (a) the effects of racism and oppression result in creating incredible obstacles to successful learning, (b) positive identity formation and the importance of family and community are essential in student learning, (c) the use of best practice in science education, including the use of curricular cultural integration for American Indian learners, supports student success, (d) the motivational need for student-directed educational opportunities (science fair/inquiry based research) is evident, (e) supportive teacher-student relationships in high school positively influences successful transitions into higher education.

    2012-08-01

    In 2005, Swiss citizens endorsed a moratorium on gene technology, resulting in the prohibition of the commercial cultivation of genetically modified crops and the growth of genetically modified animals until 2013. However, scientific research was not affected by this moratorium, and in 2008, GMO field experiments were conducted that allowed us to examine the factors that influence their acceptance by the public. In this study, trust and confidence items were analyzed using principal component analysis. The analysis revealed the following three factors: "economy/health and environment" (value similarity based trust), "trust and honesty of industry and scientists" (value similarity based trust), and "competence" (confidence). The results of a regression analysis showed that all the three factors significantly influenced the acceptance of GM field experiments. Furthermore, risk communication scholars have suggested that fairness also plays an important role in the acceptance of environmental hazards. We, therefore, included measures for outcome fairness and procedural fairness in our model. However, the impact of fairness may be moderated by moral conviction. That is, fairness may be significant for people for whom GMO is not an important issue, but not for people for whom GMO is an important issue. The regression analysis showed that, in addition to the trust and confidence factors, moral conviction, outcome fairness, and procedural fairness were significant predictors. The results suggest that the influence of procedural fairness is even stronger for persons having high moral convictions compared with persons having low moral convictions. © 2012 Society for Risk Analysis.

    2016-10-01

    CosmoQuest is embarking on a five-year effort to increase student participation in science fairs through nation-wide training of teachers, science educators, and scientists. The program focuses on helping teachers attain the needed content knowledge and skills to support creation of meaningful science fair research projects. . This includes supporting teachers' understanding of how to engage students in age-appropriate projects as young science and engineering professionals. If successful, students will create their own understanding of STEM content through research. This occurs when students are guided into learning where they become involved at a level that makes it possible for them to independently ask questions and investigate answers by seeking patterns, testing, building conceptual models, and/or designing technology.To support this kind of engagement, we are curating and creating resources to support students of all ages and abilities. Students at different age levels generally have very different developmental reasoning abilities, and engagement and learning are increased when students use age-appropriate reasoning abilities. For instance primary students are effective in observing, communicating, and comparing. As they get older they develop abilities in sequencing and finding relationships. At middle school they add inferring and finally in high school the acquired skills for applying ideas from many disciplines to create more complex understanding.Through a comprehensive program of curriculum development, educator professional development, and building strategic partnerships, we will increase the number and quality of space science related science fair projects in the United States. CosmoQuest is funded through individual donations, through NASA Cooperative Agreement NNX16AC68A, and through additional grants and contracts that are listed on the About page of our website, cosmoquest.org.

  12. Science Fairs and Observational Science: A Case History from Earth Orbit

    Lowman, Paul D., Jr.; Smith, David E. (Technical Monitor)

    2002-01-01

    Having judged dozens of science fairs over the years, I am repeatedly disturbed by the ground rules under which students must prepare their entries. They are almost invariably required to follow the "scientific method," involving formulating a hypothesis, a test of the hypothesis, and then a project in which this test is carried out. As a research scientist for over 40 years, I consider this approach to science fairs fundamentally unsound. It is not only too restrictive, but actually avoids the most important (and difficult) part of scientific research: recognizing a scientific problem in the first place. A well-known example is one of the problems that, by his own account, stimulated Einstein's theory of special relativity: the obvious fact that when an electric current is induced in a conductor by a magnetic field , it makes no difference whether the field or the conductor is actually (so to speak) moving. There is in other words no such thing as absolute motion. Physics was transformed by Einstein's recognition of a problem. Most competent scientists can solve problems after they have been recognized and a hypothesis properly formulated, but the ability to find problems in the first Place is much rarer. Getting down to specifics, the "scientific method" under which almost all students must operate is actually the experimental method, involving controlled variables, one of which, ideally, is changed at a time. However, there is another type of science that can be called observational science. As it happens, almost all the space research I have carried out since 1959 has been this type, not experimental science.

  14. The Compressed Baryonic Matter experiment at FAIR

    Höhne, Claudia

    2018-02-01

    The CBM experiment will investigate highly compressed baryonic matter created in A+A collisions at the new FAIR research center. With a beam energy range up to 11 AGeV for the heaviest nuclei at the SIS 100 accelerator, CBM will investigate the QCD phase diagram in the intermediate range, i.e. at moderate temperatures but high net-baryon densities. This intermediate range of the QCD phase diagram is of particular interest, because a first order phase transition ending in a critical point and possibly new highdensity phases of strongly interacting matter are expected. In this range of the QCD phase diagram only exploratory measurements have been performed so far. CBM, as a next generation, high-luminosity experiment, will substantially improve our knowledge of matter created in this region of the QCD phase diagram and characterize its properties by measuring rare probes such as multi-strange hyperons, dileptons or charm, but also with event-by-event fluctuations of conserved quantities, and collective flow of identified particles. The experimental preparations with special focus on hadronic observables and strangeness is presented in terms of detector development, feasibility studies and fast track reconstruction. Preparations are progressing well such that CBM will be ready with FAIR start. As quite some detectors are ready before, they will be used as upgrades or extensions of already running experiments allowing for a rich physics program prior to FAIR start.

Indeed, whether science communicators acknowledge it or not, they get to decide both which knowledge is shared (by choosing which topic is communicated), and who gets access to this knowledge (by choosing which audience it is presented to). As a result, the decisions of science communicators have important implications for epistemic justice: how knowledge is distributed fairly and equitably. This paper presents an overview of issues related to epistemic justice for science communication, and argues that there are two quite distinct ways in which science communicators can be just (or unjust) in the way they distribute knowledge. Both of these paths will be considered before concluding that, at least on one of these accounts, science communication as a field and as a practice is fundamentally epistemically unjust. Possible ways to redress this injustice are suggested.

  3. Evaluation of a High School Fair Program for Promoting Successful Inquiry-based Learning

    NASA Astrophysics Data System (ADS)

    Betts, Julia Nykeah

    The success of inquiry-based learning (IBL) in supporting science literacy can be challenged when students encounter obstacles in the absence of proper support. This research is intended to evaluate the effectiveness of an Oregon public school district's regional science fair coaching program in promoting inquiry skills and positive attitudes toward science in participating high school students. The purpose of this study was to better understand students' perception of program support, obstacles or barriers faced by students, and potential benefits of IBL facilitated by the science fair program. Data included responses to informal and semi-structured interviews, an anonymous survey, a Skills assessment of final project displays, and an in-depth case study on three students' experiences. Results suggest that the science fair program can properly engage participants in authentic IBL. However, when assessing the participant's final project displays, I found that previous fair experience did not significantly increase mean scores as identified by the official Oregon Department of Education (ODE) scoring guides. Based on results from the case study, it is suggested that participants' low science self-concept, poor understanding of inquiry skills, and inability to engage in reflective discourse may reduce students' abilities to truly benefit. Recommendations to address this discrepancy include identifying specific needs of students through a pre--fair survey to develop more targeted support, and providing new opportunities to develop skills associated with science-self concept, understanding of inquiry and reflective discourse. In addition, results suggest that students would benefit from more financial support in the form of grants, and more connections with knowledgeable mentors.

    2010-04-01

    The purpose of this study was to describe the experiences of unsuccessful applicants for permanent nursing positions with regard to the fairness of the recruitment process. The international shortage of recruits in nursing and the rapidly increasing number of nurses retiring implies new challenges for recruitment. The nurses' experiences of fairness affect the availability of nurses and the attractiveness of the organization. The recruitment process is approached through traditional organizational justice theories. The material was gathered from thematic interviews with 12 nurses who had applied for a permanent nursing position but were not selected. The material was analysed using theory-driven content analysis. The nurses felt differently about the result of the recruitment process. The experience of distributive justice alone was not significant in terms of the general sense of justice, since other dimensions of justice compensated for it. The effect of applicants' experiences of fair treatment in the recruitment process affected their future behaviour positively, negatively or not at all. and implications for nursing management It is crucial to recognize applicants' experiences of the fairness of the recruitment process, because unsuccessful applicants constitute a pool of potential new employees. Furthermore, applicants with different experiences cannot be seen as a homogenous group. For example, internal applicants with negative experiences pose challenges for nursing management with regard to retaining them in the organization.

    Recreational drones, also known as unmanned aerial vehicles (UAVs), provide an ideal platform for engaging students in science, technology, engineering, and math (STEM) investigations for science fair projects, after-school clubs, and in-class activities. UAVs are very popular (estimate of >1 million received as gifts this past year), relatively inexpensive (<$100), weigh less than 250g (don't require FAA registration), are modifiable, and can carry small instrument packages. Seeing the world from above can stimulate curiosity and give students a reason to engage in the Next Generation Science Standards (NGSS) process of science and engineering practices by designing and carrying out their own investigations. Using drones to facilitate experiments, students also participate in engineering design: they may choose off-the-shelf sensors or build DIY sensors to carry on their UAVs. Leveraging the learning potential of UAVs, the Federation of Earth Science Information Partners (ESIP) Education Committee has been developing an e-book of learning activities and investigation suggestions for secondary education students. The freely available download incorporates UAV civility and safety through a pre-flight checklist and flying guidelines, suggests science and flight team roles, and advocates robust data and metadata-collection practices. The ESIP team also worked with an engineer to build a 33-gram prototype environmental logger called SABEL (Shelley (Olds) and Bob's Environmental Logger). SABEL collects temperature, humidity, and GPS position assembled on an Arduino board. This presentation will elaborate upon the year-long process of working with educators via webinars and a 1-day workshop at the 2016 ESIP summer meeting and beyond. It will also provide examples of student-led investigations, instructions for building the SABEL sensor package, insights gleaned from workshop feedback - and - the status of the new e-book compilation of student-focused activities using

    The scientific goal of the CBM (Compressed Baryonic Matter) experiment at FAIR (Darmstadt) is to explore the phase diagram of strongly interacting matter at highest baryon densities. The physics program of the CBM experiment is complimentary to the programs to be realized at MPD and BMN facilities at NICA and will start with beam derived by the SIS100 synchrotron. The 5.15 MJ superconducting dipole magnet will be used in the silicon tracking system of the CBM detector. The magnet will provide a magnetic field integral of 1 Tm which is required to obtain a momentum resolution of 1% for the track reconstruction. The results of the development of dipole magnet of the CBM experiment are presented.

  1. How high school science-related experiences influenced science career persistence

    NASA Astrophysics Data System (ADS)

    Shaw, Andrew D.

    The events of 9/11 brought into focus two ongoing trends that were present before this tragedy and have continued since: (1) The United States needs more scientists if it is to ensure its freedoms and maintain its economy. (2) The number of scientists in the "pipeline" is declining because of the diminished presence of foreign scientists (they are wanted in their own countries), the under-representation of minorities and women, and the reduced numbers of students able and willing to take on the scholastic rigors necessary for a science or engineering degree. Though much has been written about improving science education, and numerous projects have been conducted to promote it, few education researchers have questioned the scientists themselves about the experiences, practices, and people that positively influenced them, particularly during their pre-college years. Towards this end, thirty-two scientists were interviewed in order to address four research questions: (1) How did practicing scientists' personal relationships with their science teachers influence their decision to pursue a career in science? (2) What pedagogical methods (e.g. lectures, demonstrations, "hands-on" work, problem solving, small groups) used in their high school science courses, if any, played a significant role in propelling certain students towards a career as a practicing scientist? (3) What high school science-related support structures (e.g. labs, equipment, textbooks, technology), if any, played a significant role in propelling certain students towards a career as a practicing scientist? (4) What high school science-related educational activities (e.g. science fairs, clubs, summer internships), if any, played a significant role in propelling certain students towards a career as a practicing scientist? Some of the scientists reported that they knew they were headed towards a career in science before they even entered high school, while others did not make a decision about a science

  2. Fairness overrides reputation: the importance of fairness considerations in altruistic cooperation

    Behavioral findings in several strategic games indicate that people punish others if they think they are being treated unequally, even at the cost of minimizing their own material payoff. We investigated the primary driving force behind such non-self-regarding behavior, so-called, altruistic cooperation. In all of our studies, a mini ultimatum game was played either one-shot (in Experiment 1a and 1b) or repeatedly (Experiment 2), and rejections of inequitable distribution were taken as a measure of altruistic cooperation. In Experiment 1a, we replicated previous findings indicating that the key mechanism contributing to the emergence of altruistic cooperation is fairness considerations. In Experiment 1b, we delved into the relative importance of two aspects of fairness considerations (i.e., outcome fairness and intentions) and showed that both aspects were effective in determining the level of altruistic cooperation, with the contribution of intentions being more important. In Experiment 2, we investigated the effect of the opportunity for reputation building and future interaction on altruistic cooperation. We found that these factors became influential only when fairness considerations were weakened, particularly, as a result of the removal of the possible intentions behind an offer. PMID:23760110

    NASA Astrophysics Data System (ADS)

    Pearson, Robert Wayne

    In response to the need for evaluating the effectiveness of the 1996 Wood Magic Science Fair (WMSF) at Mississippi State University's Forest and Wildlife Research Center/Forest Products Laboratory, two tests were developed. One test was designed for third-grade students and one for fourth-grade students who would attend the WMSF. Both tests have multiple choice answers and contained thirteen questions each. Five of the questions addressed general issues of the forest products industry that would be mentioned in an opening video but not stressed in the oral presentations of the WMSF. The students would have no active involvement in these presentations. These general issue questions represent passive involvement teaching. The eight remaining questions addressed specific information that would be stressed in the WMSF oral presentations and would allow students to actively participate in the presentations. The participation of the students in these presentations represents participatory teaching. The tests were given to the students (third and fourth grades) both before they attended the fair as a pre-test and after their attendance as a post-test with the only difference being that the multiple choice answers were arranged in a different order. Classroom teachers administered the tests to the students. The test results were evaluated for each class individually. Each question was evaluated and the results recorded in a table. The general information questions were grouped together as were the specific information questions. This grouping allowed a comparison to be made between passive and participatory learning. The results from the tests will help those making the science fair presentations evaluate their materials and methods. Statistical analysis of the results would indicate which questions had a significant change in the number of correct answers between the pre-test and post-test. This information will help the Fair planners and presenters in developing future

    2006-12-01

    For this outreach project we created watershed scale field activities in the Mendenhall Glacier system in Juneau, Alaska to introduce pre-college students to earth surface processes. These activities were designed to teach field data collection methods and to provide experiences that included exposure to the disciplines of glaciology, hydrology, and geomorphology. Students used their own observations to understand the on-going effects of warming climate in southeastern Alaska. Twenty seven, pre-college students from throughout the state participated in a 5-day, two-credit, introductory college-level course. This course was designed to introduce them to earth science as practiced in the field. Students divided their time between field sessions with data collection and indoor GIS labs. EDGE field excursions enabled students to learn about glacial geomorphology from river rafts, to collect stream discharge and other hydrologic data in local streams, and to integrate glacier recession observations with GPS waypoints collected from observed recessional positions. In labs at the University of Alaska Southeast campus, EDGE students were introduced to the fundamentals of ArcGIS. They downloaded their GPS waypoints onto modern and historic maps. They analyzed their stream flow data and created dynamic maps using their own observations in the field. During Fall 2006 semester, the students will generate earth science projects in their villages and towns that they can complete and present to their peers. EDGE teachers who attended a 10 day workshop in June will mentor their EDGE students. EDGE teachers and students will return to the UAS Juneau campus in March 2007 for a symposium. EGDE students will present their projects to Juneau area undergraduates and Juneau School District K-12 classes. In addition EDGE high school students will have the option to enter and compete in the Southeast Alaska Regional Science Fair held the same weekend. Funding from the National Science

  9. Science as experience, exploration, and experiments: elementary teachers' notions of `doing science'

    NASA Astrophysics Data System (ADS)

    Murphy, Ashley N.; Luna, Melissa J.; Bernstein, Malayna B.

    2017-11-01

    Much of the literature on science teaching suggests that elementary teachers lack relevant prior experiences with science. This study begins to reframe the deficit approach to research in science teaching by privileging the experiences elementary teachers have had with science - both in and out of schools - throughout their lives. Our work uses identity as a lens to examine the complexities of elementary teachers' narrative accounts of their experiences with science over the course of their lives. Our findings identify components of teachers' science-related experiences in order to lay the groundwork for making connections between teachers' personal experiences and professional practice. This work demonstrates that teachers' storied lives are important for educational researchers and teacher educators, as they reveal elements of teaching knowledge that may be productive and resourceful for refining teachers' science practice.

    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.

    2015-04-01

    FAIRNESS 2014 was the third edition in a series of workshops designed to bring together excellent international young scientists with research interests focused on physics at FAIR (Facility for Antiproton and Ion Research) and was held on September 22-27 2014 in Vietri sul Mare, Italy. The topics of the workshops cover a wide range of aspects in both theoretical developments and current experimental status, concentrated around the four scientific pillars of FAIR. FAIR is a new accelerator complex with brand new experimental facilities, that is currently being built next to the existing GSI Helmholtzzentrum for Schwerionenforschung close to Darmstadt, Germany. The spirit of the conference is to bring together young scientists, e.g. advanced PhD students and postdocs and young researchers without permanent position to present their work, to foster active informal discussions and build up of networks. Every participant in the meeting with the exception of the organizers gives an oral presentation, and all sessions are followed by an hour long discussion period. During the talks, questions are anonymously collected in a box to stimulate discussions. The broad physics program at FAIR is reflected in the wide range of topics covered by the workshop: • Physics of hot and dense nuclear matter, QCD phase transitions and critical point • Nuclear structure, astrophysics and reactions • Hadron Spectroscopy, Hadrons in matter and Hypernuclei • New developments in atomic and plasma physics • Special emphasis is put on the experiments CBM, HADES, PANDA, NUSTAR, APPA and related experiments For each of these different areas one invited speaker was selected to give a longer introductory presentation. The write-ups of the talks presented at FAIRNESS 2014 are the content of this issue of Journal of Physics: Conference Series and have been refereed according to the IOP standard for peer review. This issue constitutes therefore a collection of the forefront of research that

  17. FAIR - Cosmic Matter in the Laboratory

    NASA Astrophysics Data System (ADS)

    Stöcker, Horst; Stöhlker, Thomas; Sturm, Christian

    2015-06-01

    To explore cosmic matter in the laboratory - this fascinating research prospect becomes available at the Facility for Antiproton and Ion Research, FAIR. The new facility is being constructed within the next five years adjacent to the existing accelerator complex of the GSI Helmholtz Centre for Heavy Ion Research at Darmstadt/Germany, expanding the research goals and technical possibilities substantially. This includes new insights into the dynamics of supernovae depending on the properties of short-lived neutron-rich nuclei which will be investigated with intense rare isotope beams. New insights will be provided into the interior of stars by exploring dense plasmas with intense heavy-ion beams combined with a high-performance laser - or into neutron star cores by probing the highest baryon densities in relativistic nucleus-nucleus collisions at unprecedented collision rates. To the latter, the properties of hadrons play an important part which will be systematically studied by high precision hadron spectroscopy with antiproton beams at unmatched intensities. The worldwide unique accelerator and experimental facilities of FAIR will open the way for a broad spectrum of unprecedented fore-front research supplying a large variety of experiments in hadron, nuclear, atomic and plasma physics as well as biomedical and material science which will be briefly described in this article. This article is based on the FAIR Green Paper [4] and gives an update of former publications [5] - [12].

  19. Student experience of school science

    2017-09-01

    This paper presents the findings of a two-phase mixed methods research study that explores the link between experiences of school science of post-16 students and their decisions to take up science for their higher studies. In the first phase, students aged 16-17 (n = 569) reflected on the past five years of their school science experience in a quasi-longitudinal approach to determine a typology of experiences. The second phase entailed data collection through interviews of a sample of these students (n = 55) to help triangulate and extend findings from the first phase. Students taking up science post-16 reported significantly more positive experiences of school science than students who had decided not to take science further. Of school-related factors influencing experiences of school science curriculum content was the most important followed by being interested and motivated in the subject. There is evidence that interest and motivation in science depend on teacher practice and the perception of science as a difficult subject.

    The commonalities between the ALICE and FAIR experiments and their computing requirements led to the development of large parts of a common software framework in an experiment independent way. The FairRoot project has already shown the feasibility of such an approach for the FAIR experiments and extending it beyond FAIR to experiments at other facilities[1, 2]. The ALFA framework is a joint development between ALICE Online- Offline (O2) and FairRoot teams. ALFA is designed as a flexible, elastic system, which balances reliability and ease of development with performance using multi-processing and multithreading. A message- based approach has been adopted; such an approach will support the use of the software on different hardware platforms, including heterogeneous systems. Each process in ALFA assumes limited communication and reliance on other processes. Such a design will add horizontal scaling (multiple processes) to vertical scaling provided by multiple threads to meet computing and throughput demands. ALFA does not dictate any application protocols. Potentially, any content-based processor or any source can change the application protocol. The framework supports different serialization standards for data exchange between different hardware and software languages.

  3. The Compressed Baryonic Matter Experiment at FAIR

    NASA Astrophysics Data System (ADS)

    Senger, Peter

    Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At top RHIC and LHC energies, the QCD phase diagram is studied at very high temperatures and very low net-baryon densities. These conditions presumably existed in the early universe about a microsecond after the big bang. For larger net-baryon densities and lower temperatures, it is expected that the QCD phase diagram exhibits a rich structure such as a critical point, a first order phase transition between hadronic and partonic matter, or new phases like quarkyonic matter. The experimental discovery of these prominent landmarks of the QCD phase diagram would be a major breakthrough in our understanding of the properties of nuclear matter. The Compressed Baryonic Matter (CBM) experiment will be one of the major scientific pillars of the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt. The goal of the CBM research program is to explore the QCD phase diagram in the region of high baryon densities using high-energy nucleus-nucleus collisions. This includes the study of the equation-of-state of nuclear matter at neutron star core densities, and the search for the deconfinement and chiral phase transitions. The CBM detector is designed to measure rare diagnostic probes such as multi-strange hyperons, charmed particles and vector mesons decaying into lepton pairs with unprecedented precision and statistics. Most of these particles will be studied for the first time in the FAIR energy range. In order to achieve the required precision, the measurements will be performed at very high reaction rates of 100 kHz to 10 MHz. This requires very fast and radiation-hard detectors, and a novel data read-out and analysis concept based on free streaming front-end electronics and a high-performance computing cluster for online event selection. The layout, the physics performance, and the status of the proposed CBM experimental

    Pathogen-Host interaction data is core to our understanding of disease processes and their molecular/genetic bases. Facile access to such core data is particularly important for the plant sciences, where individual genetic and phenotypic observations have the added complexity of being dispersed over a wide diversity of plant species vs. the relatively fewer host species of interest to biomedical researchers. Recently, an international initiative interested in scholarly data publishing proposed that all scientific data should be "FAIR"-Findable, Accessible, Interoperable, and Reusable. In this work, we describe the process of migrating a database of notable relevance to the plant sciences-the Pathogen-Host Interaction Database (PHI-base)-to a form that conforms to each of the FAIR Principles. We discuss the technical and architectural decisions, and the migration pathway, including observations of the difficulty and/or fidelity of each step. We examine how multiple FAIR principles can be addressed simultaneously through careful design decisions, including making data FAIR for both humans and machines with minimal duplication of effort. We note how FAIR data publishing involves more than data reformatting, requiring features beyond those exhibited by most life science Semantic Web or Linked Data resources. We explore the value-added by completing this FAIR data transformation, and then test the result through integrative questions that could not easily be asked over traditional Web-based data resources. Finally, we demonstrate the utility of providing explicit and reliable access to provenance information, which we argue enhances citation rates by encouraging and facilitating transparent scholarly reuse of these valuable data holdings.

  8. Partner choice creates fairness in humans.

    PubMed

    Debove, Stéphane; André, Jean-Baptiste; Baumard, Nicolas

    2015-06-07

    Many studies demonstrate that partner choice has played an important role in the evolution of human cooperation, but little work has tested its impact on the evolution of human fairness. In experiments involving divisions of money, people become either over-generous or over-selfish when they are in competition to be chosen as cooperative partners. Hence, it is difficult to see how partner choice could result in the evolution of fair, equal divisions. Here, we show that this puzzle can be solved if we consider the outside options on which partner choice operates. We conduct a behavioural experiment, run agent-based simulations and analyse a game-theoretic model to understand how outside options affect partner choice and fairness. All support the conclusion that partner choice leads to fairness only when individuals have equal outside options. We discuss how this condition has been met in our evolutionary history, and the implications of these findings for our understanding of other aspects of fairness less specific than preferences for equal divisions of resources. © 2015 The Author(s) Published by the Royal Society.

    Reactions to decisions are shaped by both outcome and procedural fairness. Moreover, outcome and procedural fairness interact to influence beliefs and behaviors. However, different types of "process/outcome" interaction effects have emerged. Many studies have shown that people react particularly negatively when they receive unfair or unfavorable outcomes accompanied by unfair procedures (the "low-low" interactive pattern). However, others find that people react especially positively when they receive fair or favorable outcomes accompanied by fair procedures (the "high-high" interactive pattern). We propose that trust in decision-making authorities dictates the form of the process/outcome interaction. Across three studies, when trust was high, the "low-low" interactive pattern emerged. When trust was low, the "high-high" interactive pattern emerged. The findings suggest that when people's experience of outcome and procedural fairness diverged from how they expected to be treated, they reacted in the direction of their experiences; otherwise, their reactions were consistent with their expectations. © 2014 by the Society for Personality and Social Psychology, Inc.

  10. Hypernuclear physics studies of the PANDA experiment at FAIR

    2014-09-01

    Hypernuclear research will be one of the main topics addressed by the PANDA experiment at the planned Facility for Antiproton and Ion Research FAIR at Darmstadt (Germany). http://www. gsi.de, http://www.gsi.de/fair/. Thanks to the use of stored overline {p} beams, copious production of double Λ hypernuclei is expected at the PANDA experiment, which will enable high precision γ spectroscopy of such nuclei for the first time, and consequently a unique chance to explore the hyperon-hyperon interaction. In particular, ambiguities of past experiments in determining the strength of the ΛΛ interaction will be avoided thanks to the excellent energy precision of a few keV (FWHM) achieved by germanium detectors. Such a resolution capability is particularly needed to resolve the small energy spacing of the order of (10-100) keV, which is characteristic from the spin doublet in hypernuclei the so -called "hypernuclear fine structure". In comparison to previous experiments, PANDA will benefit from a novel technique to assign the various observable γ-transitions in a unique way to specific double hypernuclei by exploring various light targets. Nevertheless, the ability to carry out unique assignments requires a devoted hypernuclear detector setup. This consists of a primary nuclear target for the production of {Ξ }-+overline {Ξ } pairs, a secondary active target for the hypernuclei formation and the identification of associated decay products and a germanium array detector to perform γ spectroscopy. Moreover, one of the most challenging issues of this project is the fact that all detector systems need to operate in the presence of a high magnetic field and a large hadronic background. Accordingly, the need of an innovative detector concept will require dramatic improvements to fulfil these conditions and that will likely lead to a new generation of detectors. In the present talk details concerning the current status of the activities related to the detector developments

    2016-01-01

    Recent evidence suggests that infants possess a rudimentary sensitivity to fairness: infants expect resources to be distributed fairly and equally, and prefer individuals that distribute resources fairly over those that do so unfairly. The goal of the present work was to determine whether infants' evaluations of fair and unfair individuals also includes an understanding that fair individuals are worthy of praise and unfair individuals are worthy of admonishment. After watching individuals distribute goods fairly or unfairly to recipients, 15-month-old (Experiments 1 and 2) and 13-month-old (Experiment 3) infants took part in a test phase in which they saw only the distributors' faces accompanied by praise or admonishment. Across all experiments, infants differentially shifted their visual attention to images of the fair and unfair distributors as a function of the accompanying praise or admonishment, although the direction in which they did so varied by age. Thus, by the start of the second year of life, infants appear to perceive fair individuals as morally praiseworthy and unfair individuals as morally blameworthy. PMID:27570495

    Status within social hierarchies has great effects on the lives of socially organized mammals. Its effects on human behavior and related physiology, however, is relatively little studied. The present study investigated the impact of military rank on fairness and behavior in relation to salivary cortisol (C) and testosterone (T) levels in male soldiers. For this purpose 180 members of the Austrian Armed Forces belonging to two distinct rank groups participated in two variations of a computer-based guard duty allocation experiment. The rank groups were (1) warrant officers (high rank, HR) and (2) enlisted men (low rank, LR). One soldier from each rank group participated in every experiment. At the beginning of the experiment, one participant was assigned to start standing guard and the other participant at rest. The participant who started at rest could choose if and when to relieve his fellow soldier and therefore had control over the experiment. In order to trigger perception of unfair behavior, an additional experiment was conducted which was manipulated by the experimenter. In the manipulated version both soldiers started in the standing guard position and were never relieved, believing that their opponent was at rest , not relieving them. Our aim was to test whether unfair behavior causes a physiological reaction. Saliva samples for hormone analysis were collected at regular intervals throughout the experiment. We found that in the un-manipulated setup high-ranking soldiers spent less time standing guard than lower ranking individuals. Rank was a significant predictor for C but not for T levels during the experiment. C levels in the HR group were higher than in the LR group. C levels were also elevated in the manipulated experiment compared to the un-manipulated experiment, especially in LR. We assume that the elevated C levels in HR were caused by HR feeling their status challenged by the situation of having to negotiate with an individual of lower military

    Zimbabwean villagers of distinct background have resettled in government-organized land reforms for more than three decades. Against this backdrop, I assess the level of social cohesion in some of the newly established communities by estimating the average preferences for fairness in a structural model of bounded rationality. The estimations are based on behavioral data from an ultimatum game field experiment played by 234 randomly selected households in 6 traditional and 14 resettled villages almost two decades after resettlement. Equal or higher degrees of fairness are estimated in all resettlement schemes. In one, or arguably two, out of three distinct resettlement schemes studied, the resettled villagers exhibit significantly higher degrees of fairness ( ) and rationality ( ) than those who live in traditional villages. Overall, villagers appear similarly rational, but the attitude toward fairness is significantly stronger in resettled communities ( ). These findings are consistent with the idea of an increased need for cooperation required in recommencement. PMID:23724095

    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.

The topics of the workshop cover a wide range of aspects in both theoretical developments and current experimental status, concentrated around the four scientific pillars of FAIR. FAIR is a new accelerator complex with brand new experimental facilities, that is currently being built next to the existing GSI Helmholtzzentrum for Schwerionenforschung close to Darmstadt, Germany. The spirit of the conference is to bring together young scientists, e.g. advanced PhD students and postdocs and young researchers without permanent position to present their work, to foster active informal discussions and build up of networks. Every participant in the meeting with the exception of the organizers gives an oral presentation, and all sessions are followed by an hour long discussion period. During the talks, questions are anonymously collected in box to stimulate discussions. Since the physics program of FAIR is very broad, this is reflected in the wide range of topics covered at the Conference: Physics of hot and dense nuclear matter, QCD phase transitions and critical point Nuclear structure, astrophysics and reactions Hadron spectroscopy, Hadrons in matter and Hypernuclei Special emphasis is put on the experiments CBM, HADES, PANDA, NuSTAR, as well as NICA and the RHIC low beam energy scan New developments in atomic and plasma physics For all of these different areas one invited speaker was selected to give a longer introductory presentation.

    The capabilities of the Space Station glovebox facility is described. Tentatively scheduled to be launched in 1999, this facility called the Microgravity Sciences Glovebox (MSG), will provide a robust and sophisticated platform for doing microgravity experiments on the Space Station. It will provide an environment not only for testing and evaluating experiment concepts, but also serve as a platform for doing fairly comprehensive science investigations. Its design has evolved substantially from the middeck glovebox, now flown on Space Shuttle missions, not only in increased experiment volume but also in significant capability enhancements. The system concept, functionality and architecture are discussedmore » along with technical information that will benefit potential science investigators.« less

    In the present research, the authors examined the effect of procedural fairness and rewarding leadership style on an important variable for employees: self-esteem. The authors predicted that procedural fairness would positively influence people's reported self-esteem if the leader adopted a style of rewarding behavior for a job well done. Results from a scenario experiment, a laboratory experiment, and an organizational survey indeed show that procedural fairness and rewarding leadership style interacted to influence followers' self-esteem, such that the positive relationship between procedural fairness and self-esteem was more pronounced when the leadership style was high in rewarding behavior. Implications in terms of integrating the leadership and procedural fairness literature are discussed.

  6. Physical experience enhances science learning.

    Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to students' thinking. We tested whether physical experience with angular momentum increases involvement of sensorimotor brain systems during students' subsequent reasoning and whether this involvement aids their understanding. The physical experience, a brief exposure to forces associated with angular momentum, significantly improved quiz scores. Moreover, improved performance was explained by activation of sensorimotor brain regions when students later reasoned about angular momentum. This finding specifies a mechanism underlying the value of physical experience in science education and leads the way for classroom practices in which experience with the physical world is an integral part of learning. © The Author(s) 2015.

    P̅ANDA is a future hadron and nuclear physics experiment at the FAIR facility in construction in Darmstadt, Germany. In contrast to the majority of current experiments, PANDA's strategy for data acquisition is based on event reconstruction from free-streaming data, performed in real time entirely by software algorithms using global detector information. This paper reports the status of the development of algorithms for the reconstruction of charged particle tracks, optimized online data processing applications, using General-Purpose Graphic Processing Units (GPU). Two algorithms for trackfinding, the Triplet Finder and the Circle Hough, are described, and details of their GPU implementations are highlighted. Average track reconstruction times of less than 100 ns are obtained running the Triplet Finder on state-of- the-art GPU cards. In addition, a proof-of-concept system for the dispatch of data to tracking algorithms using Message Queues is presented.

    The Facility for Antiproton and Ion Research, FAIR, is a new particle accelerator facility to be built at the GSI site in Germany. The research at FAIR will cover a wide range of topics in nuclear and hadron physics, high density plasma and atomic physics, and applications in condensed matter physics and biology. A 1.1 km circumference double ring of rapidly cycling 100 and 300 Tm synchrotrons, will be FAIR's central accelerator system. It will be used to produce, inter alia, high intensity secondary beams of antiprotons and short-lived radioactive nuclei. A subsequent suite of cooler and storage rings will deliver heavy ion and antiproton beams of unprecedented quality. Large experiments are presently being designed by the NUSTAR, PANDA, PAX, CBM, SPARC, FLAIR, HEDgeHOB and BIOMAT collaborations.

    The criteria for the selection of the experimental areas and individual experiments were that the experiment or area must make a meaningful contribution to the field of material science and that the space environment was either an absolute requirement for the successful execution of the experiment or that the experiment can be more economically or more conveniently performed in space. A number of experimental areas and individual experiments were recommended for further consideration as space experiments. Areas not considered to be fruitful and others needing additional analysis in order to determine their suitability for conduct in space are also listed. Recommendations were made concerning the manner in which these materials science experiments are carried out and the related studies that should be pursued.

    Pathogen-Host interaction data is core to our understanding of disease processes and their molecular/genetic bases. Facile access to such core data is particularly important for the plant sciences, where individual genetic and phenotypic observations have the added complexity of being dispersed over a wide diversity of plant species vs. the relatively fewer host species of interest to biomedical researchers. Recently, an international initiative interested in scholarly data publishing proposed that all scientific data should be “FAIR”—Findable, Accessible, Interoperable, and Reusable. In this work, we describe the process of migrating a database of notable relevance to the plant sciences—the Pathogen-Host Interaction Database (PHI-base)—to a form that conforms to each of the FAIR Principles. We discuss the technical and architectural decisions, and the migration pathway, including observations of the difficulty and/or fidelity of each step. We examine how multiple FAIR principles can be addressed simultaneously through careful design decisions, including making data FAIR for both humans and machines with minimal duplication of effort. We note how FAIR data publishing involves more than data reformatting, requiring features beyond those exhibited by most life science Semantic Web or Linked Data resources. We explore the value-added by completing this FAIR data transformation, and then test the result through integrative questions that could not easily be asked over traditional Web-based data resources. Finally, we demonstrate the utility of providing explicit and reliable access to provenance information, which we argue enhances citation rates by encouraging and facilitating transparent scholarly reuse of these valuable data holdings.

    2018-03-01

    The Silicon Tracking System (STS) is the central detector in the Compressed Baryonic Matter (CBM) experiment at FAIR. Operating in the 1Tm dipole magnetic field, the STS will enable pile-up free detection and momentum measurement of the charged particles originating from beam-target nuclear interactions at rates up to 10 MHz. The STS consists of 8 tracking stations based on double-sided silicon micro-strip sensors equipped with fast, self-triggering read-out electronics. With about two million read-out channels, the STS will deliver a high-rate stream of time-stamped data that is transferred to a computing farm for on-line event determination and analysis. The functional building block is a detector module consisting of a sensor, micro-cables and two front-end electronics boards. In this contribution, the development status of the STS components and the system integration is discussed and an outlook on the detector construction is given.

    While studies investigating the health effects of racial discrimination for children and youth have examined a range of effect modifiers, to date, relationships between experiences of racial discrimination, student attitudes, and health outcomes remain unexplored. This study uniquely demonstrates the moderating effects of vicarious racism and motivated fairness on the association between direct experiences of racism and mental health outcomes, specifically depressive symptoms and loneliness, among primary and secondary school students. Across seven schools, 263 students (54.4% female), ranging from 8 to 17 years old (M = 11.2, SD = 2.2) reported attitudes about other racial/ethnic groups and experiences of racism. Students from minority ethnic groups (determined by country of birth) reported higher levels of loneliness and more racist experiences relative to the majority group students. Students from the majority racial/ethnic group reported higher levels of loneliness and depressive symptoms if they had more friends from different racial/ethnic groups, whereas the number of friends from different groups had no effect on minority students' loneliness or depressive symptoms. Direct experiences of racism were robustly related to higher loneliness and depressive symptoms in multivariate regression models. However, the association with depressive symptoms was reduced to marginal significance when students reported low motivated fairness. Elaborating on the negative health effects of racism in primary and secondary school students provides an impetus for future research and the development of appropriate interventions.

    The decomposition of water by electricity, and the voltaic pile as a means of generating electricity, have both held an iconic status in the history of science as well as in the history of science teaching. These experiments featured in chemistry and physics textbooks, as well as in classroom teaching, throughout the nineteenth and twentieth centuries. This paper deals with our experiences in restaging the decomposition of water as part of a history of science course at the Norwegian University of Science and Technology, Trondheim, Norway. For the experiment we used an apparatus from our historical teaching collection and built a replica of a voltaic pile. We also traced the uses and meanings of decomposition of water within science and science teaching in schools and higher education in local institutions. Building the pile, and carrying out the experiments, held a few surprises that we did not anticipate through our study of written sources. The exercise gave us valuable insight into the nature of the devices and the experiment, and our students appreciated an experience of a different kind in a history of science course.

  2. How do leaders promote cooperation? The effects of charisma and procedural fairness.

    De Cremer, David; van Knippenberg, Daan

    2002-10-01

    The present research examined the effect of leaders' procedural fairness and perceived charisma on an important organizational process: cooperation. Both charisma and procedural fairness were predicted to have a positive effect on cooperation, and procedural fairness and charisma were predicted to interact such that their effects are stronger alone than in conjunction. Results from a scenario experiment, a cross-sectional survey, and a laboratory experiment supported these predictions. Results from the laboratory study also showed that the interactive effect of leader charisma and procedural fairness on cooperation was mediated by their interactive effect on the sense of group belongingness. It is concluded that leader charisma and procedural fairness may engender cooperation because they appeal to relational concerns.

  3. Academic attainment and the high school science experiences among high-achieving African American males

    Trice, Rodney Nathaniel

    This study examines the educational experiences of high achieving African American males. More specifically, it analyzes the influences on their successful navigation through high school science. Through a series of interviews, observations, questionnaires, science portfolios, and review of existing data the researcher attempted to obtain a deeper understanding of high achieving African American males and their limitations to academic attainment and high school science experiences. The investigation is limited to ten high achieving African American male science students at Woodcrest High School. Woodcrest is situated at the cross section of a suburban and rural community located in the southeastern section of the United States. Although this investigation involves African American males, all of whom are successful in school, its findings should not be generalized to this nor any other group of students. The research question that guided this study is: What are the limitations to academic attainment and the high school science experiences of high achieving African American males? The student participants expose how suspension and expulsion, special education placement, academic tracking, science instruction, and teacher expectation influence academic achievement. The role parents play, student self-concept, peer relationships, and student learning styles are also analyzed. The anthology of data rendered three overarching themes: (1) unequal access to education, (2) maintenance of unfair educational structures, and (3) authentic characterizations of African American males. Often the policies and practices set in place by school officials aid in creating hurdles to academic achievement. These policies and practices are often formed without meaningful consideration of the unintended consequences that may affect different student populations, particularly the most vulnerable. The findings from this study expose that high achieving African American males face major

  6. Teacher learning from girls' informal science experiences

    NASA Astrophysics Data System (ADS)

    Birmingham, Daniel J.

    School science continues to fail to engage youth from non-dominant communities (Carlone, Huan-Frank & Webb, 2011). However, recent research demonstrates that informal science learning settings support both knowledge gains and increased participation in science among youth from non-dominant communities (Dierking, 2007; Falk et al., 2007; HFRP, 2010). Despite the success, little is known about how teachers can learn from informal science practices to support student engagement in science. In this study, I examine the impact informal science experiences has for the teaching and learning of science in school contexts. This study is focused on eliciting girls' stories of informal science learning experiences and sharing these stories with science teachers to examine what they notice and make meaning of in connection with their classroom practices (van Es & Sherin, 2002). I co-constructed cases of informal science experiences with middle school females who participate in an after school science program in an urban area. These cases consisted of the girls' written stories, their explicit messages to science teachers, examples of actions taken when investigating community based science issues and transcripts of conversations between the girls and researchers. These cases were shared with local science teachers in order to investigate what they "notice" (van Es & Sherin, 2002) regarding girls' participation in informal science learning, how they make meaning of youths' stories and whether the stories influence their classroom practices. I found that the girls' use their cases to share experiences of how, where and why science matters, to express hope for school science and to critique stereotypical views that young, female, students of color from lower SES backgrounds are not interested or capable of making contributions to scientific investigations. Additionally, I found that teachers noticed powerful messages within and across the girls' cases. The messages include; 1

    2016-02-01

    Overview This paper presentation shares findings from a granted funded project that sought to expand teacher content knowledge and pedagogy within the fields of marine science and coastal resource management through the implementation of classroom citizen science projects. A secondary goal was to increase middle and high school student interest and participation in marine science and natural resources research. Background A local science & engineering fair has seen a rapid decline in secondary student participants in the past four years. Research has demonstrated that when students are a part of a system of knowledge production (citizen science) they become much more aware, involved and conscious of scientific concepts compared to traditional school laboratory and nature of science activities. This project's primary objectives were to: (a) enhance teacher content expertise in marine science, (b) enrich teacher professional learning, (c) support citizen science classroom projects and inspire student activism and marine science engagement. Methods Project goals were addressed through classroom and meaningful outdoor educational experiences that put content knowledge into field based practices. Teachers learned to apply thier expanded content knowlege through classroom citizen science projects that focus on marine resource conservation issues such as fisheries management, water quality, turtle nesting and biodiversity of coastal ecosystems. These projects would eventually become potential topics of citizen science research topics for their students to pursue. Upon completion of their professional development, participants were urged to establish student Marine Science clubs with the goal of mentoring student submissions into the local science fair. Supplemental awards were possible for the students of project participants. Findings Based on project measures participants significantly increased their knowledge and awareness of presented material marine science and

  10. Lived experiences of self-reported science-anxious students taking an interdisciplinary undergraduate science course

    NASA Astrophysics Data System (ADS)

    Minger, Mark Austin

    Having fears and frustrations while studying science topics can lead to science anxiety for some individuals. For those who experience science learning anxiety, the reality is often poor performance, lowered self-esteem, anger, and avoidance of further science courses. Using an interpretive approach, this study captures the experiences of five self-reported science anxious students as they participate in an interdisciplinary science course at the University of Minnesota. A series of three in-depth interviews were conducted with five students who were enrolled in the "Our Changing Planet" course offered at the University of Minnesota. The interviews were transcribed verbatim, coded, and analyzed thematically. Four major themes emerged from the interviews. Two of the themes involve the realities of being a science anxious student. These focus on participants' experiences of feeling frustrated, anxious and incompetent when studying both math and science; and the experiences of trying to learn science content that does not seem relevant to them. The last two themes highlight the participants' perceptions of their experiences during the "Our Changing Planet" course, including how the course seemed different from previous science courses as well as their learning experiences in cooperative groups. After presenting the themes, with supporting quotations, each theme is linked to the related literature. The essence of the participants' science anxiety experiences is presented and practical implications regarding science anxious students are discussed. Finally, insights gained and suggestions for further research are provided.

    2007-06-01

    Understanding the interplay of the nuclear interaction with polarized protons and the electromagnetic interaction with polarized electrons in polarized atoms is crucial to progress towards the PAX goal to eventually produce stored polarized antiproton beams at FAIR. Presently, there exist two competing theoretical scenarios: one with substantial spin filtering of (anti)protons by atomic electrons, and a second one suggesting a self-cancellation of the electron contribution to spin filtering. After a brief review of the PAX physics case for polarized antiprotons at FAIR, a detailed discussion of future investigations, including spin-filtering experiments at COSY-Jülich and at the AD of CERN is presented.

    2018-01-01

    We examined the influence of three reference points (minimum requirements [MR], the status quo [SQ], and goal [G]) proposed by the tri-reference point (TRP) theory on fairness and satisfaction perceptions of pay in three laboratory experiments. To test the effects, we manipulated these three reference points both implicitly (Experiment 1) and explicitly (Experiments 2 and 3). We also provided the information of the salary offered to a peer person that was lower than, equal to, or higher than the salary offer to the participant. As hypothesized, the results demonstrated the important role of these reference points in judging the fairness of and satisfaction with pay when they were explicitly set (an interaction between reference points and social comparison in Experiments 2 and 3, but not in Experiment 1). Participants altered their judgments when the salary was in different regions. When the salary was below MR, participants perceived very low fairness and satisfaction, even when the offer was equal to/exceeded others. When the salary was above G, participants perceived much higher fairness and satisfaction, even with disadvantageous inequality. Participants were more impacted when they were explicitly instructed of the reference points (Experiments 2 and 3) than when they were not (Experiment 1). Moreover, MR appeared to be the most important, followed by G. A Salary below MR was judged as very unacceptable, with very low fairness and satisfaction ratings. PMID:29515503

  13. Preservice science teachers' experiences with repeated, guided inquiry

    NASA Astrophysics Data System (ADS)

    Slack, Amy B.

    The purpose of this study was to examine preservice science teachers' experiences with repeated scientific inquiry (SI) activities. The National Science Education Standards (National Research Council, 1996) stress students should understand and possess the abilities to do SI. For students to meet these standards, science teachers must understand and be able to perform SI; however, previous research demonstrated that many teachers have naive understandings in this area. Teacher preparation programs provide an opportunity to facilitate the development of inquiry understandings and abilities. In this study, preservice science teachers had experiences with two inquiry activities that were repeated three times each. The research questions for this study were (a) How do preservice science teachers' describe their experiences with repeated, guided inquiry activities? (b) What are preservice science teachers' understandings and abilities of SI? This study was conducted at a large, urban university in the southeastern United States. The 5 participants had bachelor's degrees in science and were enrolled in a graduate science education methods course. The researcher was one of the course instructors but did not lead the activities. Case study methodology was used. Data was collected from a demographic survey, an open-ended questionnaire with follow-up interviews, the researcher's observations, participants' lab notes, personal interviews, and participants' journals. Data were coded and analyzed through chronological data matrices to identify patterns in participants' experiences. The five domains identified in this study were understandings of SI, abilities to conduct SI, personal feelings about the experience, science content knowledge, and classroom implications. Through analysis of themes identified within each domain, the four conclusions made about these preservice teachers' experiences with SI were that the experience increased their abilities to conduct inquiry

    Brockner, Joel

    2006-03-01

    When employees believe they are being treated fairly-when they feel heard, when they understand how and why important decisions are made, and when they believe they are respected-their companies will benefit. Research shows that practicing process fairness reduces legal costs from wrongful-termination suits, lowers employee turnover, helps generate support for new strategic initiatives, and fosters a culture that promotes innovation. What's more, it costs little financially to implement Yet few companies practice it consistently. Joel Brockner examines this paradox, exploring psychological and other reasons that cause managers to resist embracing process fairness. The fact that it's relatively inexpensive to implement, for instance, may be why some numbers-oriented executives undervalue it. Many managers believe that they practice process fairness, but 360-degree feedback tells another story. Some corporate policies actually undermine it--such as when the legal department won't let managers fully explain decisions for fear that disclosure could expose the firm to lawsuits. And, frequently, managers simply follow the all-too-human tendency to avoid uncomfortable situations. But the good news is that organizations can take concrete steps to promote greater process fairness. Many studies have shown that training programs make a big difference, and the author describes the most effective format. In addition, warning your managers that they may experience negative emotions when practicing fair process will help prepare them to cope with those feelings. Finally, role modeling fair process on the executive level will help spread the practice throughout the organization. The fact is, process fairness is the responsibility of all executives, at all levels and in all functions; it cannot be delegated to HR. The sooner managers realize that and work to make it a company norm, the better off the organization will be.

  16. Science identity construction through extraordinary professional development experiences

    NASA Astrophysics Data System (ADS)

    McLain, Bradley David

    Despite great efforts and expenditures to promote science literacy and STEM career choices, the U.S. continues to lag behind other countries in science education, diminishing our capacity for STEM leadership and our ability to make informed decisions in the face of multiple looming global issues. I suggest that positive science identity construction (the integration of science into one's sense of self so that it becomes a source of inspiration and contributes to lifelong learning) is critical for promoting durable science literacy and pro-science choices. Therefore, the focus of this study was extraordinary professional development experiences for science educators that may significantly impact their sense of self. My hypothesis was that such experiences could positively impact educators' science and science educator identities, and potentially enhance their capacities to impact student science identities. The first part of this hypothesis is examined in this study. Further, I suggest that first-person narratives play an important role in science identity construction. Presenting a new conceptual model that connects experiential learning theory to identity theory through the narrative study of lives, I explored the impacts of subjectively regarded extraordinary professional development experiences on the science identity and science educator identity construction processes for a cohort of fifteen K-12 science teachers during a science-learning-journey to explore the volcanoes of Hawaii. I used a case study research approach under the broader umbrella of a hermeneutic phenomenology to consider four individual cases as lived experiences and to consider the journey as a phenomenon unto itself. Findings suggest science and science educator identities are impacted by such an experience but with marked variability in magnitude and nature.

    Low income and uninsured individuals often have lower adherence to cancer screening for breast, cervical and colorectal cancer. Health fairs are a common community outreach strategy used to provide cancer-related health education and services. This study was a process evaluation of seven health fairs focused on cancer screening across the U.S. We conducted key-informant interviews with the fair coordinator and conducted baseline and follow-up surveys with fair participants to describe characteristics of participants as well as their experiences. We collected baseline data with participants at the health fairs and telephone follow-up surveys 6 months following the fair. Attendance across the seven health fairs ranged from 41 to 212 participants. Most fairs provided group or individual education, print materials and cancer screening during the event. Overall, participants rated health fairs as very good and participants reported that the staff was knowledgeable and that they liked the materials distributed. After the fairs, about 60% of participants, who were reached at follow-up, had read the materials provided and had conversations with others about cancer screening, and 41% talked to their doctors about screening. Based on findings from evaluation including participant data and coordinator interviews, we describe 6 areas in planning for health fairs that may increase their effectiveness. These include: 1) use of a theoretical framework for health promotion to guide educational content and activities provided, 2) considering the community characteristics, 3) choosing a relevant setting, 4) promotion of the event, 5) considerations of the types of services to deliver, and 6) evaluation of the health fair. The events reported varied in reach and the participants represented diverse races and lower income populations overall. Most health fairs offered education, print materials and onsite cancer screening. Participants reported general satisfaction with these events

    Fairness perceptions may be affected by counterfactual comparisons. Although certain studies using a two-player ultimatum game (UG) have shown that comparison with the proposers influences the responders' fairness perceptions in a gain context, the effect of counterfactual comparison in a UG with multiple responders or proposers remains unclear, especially in a loss context. To resolve these issues, this study used a modified three-player UG with multiple responders in Experiment 1 and multiple proposers in Experiment 2 to examine the influence of counterfactual comparison on fairness-related decision-making in gain and loss contexts. The two experiments consistently showed that regardless of the gain or loss context, the level of inequality of the offer and counterfactual comparison influenced acceptance rates (ARs), response times (RTs), and fairness ratings (FRs). If the offers that were received were better than the counterfactual offers, unequal offers were more likely to be accepted than equal offers, and participants were more likely to report higher FRs and to make decisions more quickly. In contrast, when the offers they received were worse than the counterfactual offers, participants were more likely to reject unequal offers than equal offers, reported lower FRs, and made decisions more slowly. These results demonstrate that responders' fairness perceptions are influenced by not only comparisons of the absolute amount of money that they would receive but also specific counterfactuals from other proposers or responders. These findings improve our understanding of fairness perceptions.

  5. Connecting science to everyday experiences in preschool settings

    Roychoudhury, Anita

    2014-06-01

    In this paper I discuss the challenges of teaching science concepts and discourse in preschool in light of the study conducted by Kristina Andersson and Annica Gullberg. I then suggest a complementary approach to teaching science at this level from the perspective of social construction of knowledge based on Vygotsky's theory (1934/1987). In addition, I highlight the importance of the relational aspect of knowing using feminist standpoint theory (Harding 2004). I also draw from feminist research on preservice elementary teachers' learning of science to further underscore the connection between learning content and everyday experiences. Combining these research strands I propose that science needs to be grounded in everyday experiences. In this regard, the idea is similar to the choices made by the teachers in the study conducted by Andersson and Gullberg but I also suggest that the everyday experiences chosen for teaching purposes be framed appropriately. In and of itself, the complexity of everyday experiences can be impediment for learning as these researchers have demonstrated. Such complexities point to the need for framing of everyday experiences (Goffman 1974) so that children can do science and construct meaning from their actions. In the conclusion of my discussion of science and its discourse in preschool settings, I provide examples of everyday experiences and their framings that have the potential for engaging children and their teachers in science.

    2014-10-17

    The human sense of fairness is an evolutionary puzzle. To study this, we can look to other species, in which this can be translated empirically into responses to reward distribution. Passive and active protest against receiving less than a partner for the same task is widespread in species that cooperate outside kinship and mating bonds. There is less evidence that nonhuman species seek to equalize outcomes to their own detriment, yet the latter has been documented in our closest relatives, the apes. This reaction probably reflects an attempt to forestall partner dissatisfaction with obtained outcomes and its negative impact on future cooperation. We hypothesize that it is the evolution of this response that allowed the development of a complete sense of fairness in humans, which aims not at equality for its own sake but for the sake of continued cooperation.

  8. Pre-college Science Experiences; Timing and Causes of Gender Influence Science Interest Levels

    It is known that female students tend to turn away from science during their pre-college years. Experiences during this time are not limited to the classroom, as cultural influences extend beyond K-12 science education and lead to the widely studied reduction in females in STEM fields. This has a large impact on climate science because currently relatively little effort is put into K-12 climate education, yet this is when college attitudes towards science are formed. To help quantify these changes, 400 surveys were collected from 4 different colleges in Oklahoma. Student responses were compared by gender against student experiences (positive and negative), and interest in science. Results of our work show that females tend to have their first positive experience with science at a younger age with friends, family and in the classroom, and have more of an interest in science when they are younger. Males in general like experiencing science more on their own, and surpass the interest levels of females late in high school and during college. While in college, males are more comfortable with science content than females, and males enjoy math and statistics more while those aspects of science were the largest areas of dislike in females. Understanding how to keep students (particularly female) interested in science as they enter their teen years is extremely important in preventing climate misconceptions in the adult population. Potential small changes such as hosting K-12 climate outreach events and including parents, as opposed to just inviting students, could greatly improve student experiences with science and hence, their understanding of climate science. Importantly, a greater focus on female students is warranted.

    2010-05-01

    Building on fairness heuristic theory, fairness theory, and trust development models, we argue that unfairly enacted procedures decrease followers' trust in the authority particularly when authorities have high power over their followers. Moreover, we expected trust to mediate procedural fairness effects on followers' attitudes (authorities' legitimacy and charisma attributed to authorities) and organizational citizenship behavior. Procedural fairness effects on these variables, as mediated by trust, should therefore also be stronger when authority power is high. The results of a single- and multisource field study and a laboratory experiment supported these predictions. These studies support the role of authority power as a theoretically and practically relevant moderator of procedural fairness effects and show that its effectiveness is explained through trust in authorities.

    DOE Office of Scientific and Technical Information (OSTI.GOV)

    Wu, Wenji; Crawford, Matt; /Fermilab

    In general, the Linux 2.6 scheduler can ensure fairness and provide excellent interactive performance at the same time. However, our experiments and mathematical analysis have shown that the current Linux interactivity mechanism tends to incorrectly categorize non-interactive network applications as interactive, which can lead to serious fairness or starvation issues. In the extreme, a single process can unjustifiably obtain up to 95% of the CPU! The root cause is due to the facts that: (1) network packets arrive at the receiver independently and discretely, and the 'relatively fast' non-interactive network process might frequently sleep to wait for packet arrival. Thoughmore » each sleep lasts for a very short period of time, the wait-for-packet sleeps occur so frequently that they lead to interactive status for the process. (2) The current Linux interactivity mechanism provides the possibility that a non-interactive network process could receive a high CPU share, and at the same time be incorrectly categorized as 'interactive.' In this paper, we propose and test a possible solution to address the interactivity vs. fairness problems. Experiment results have proved the effectiveness of the proposed solution.« less

    Triers of fact sometimes consider lineup fairness when determining the suggestiveness of an identification procedure. Likewise, researchers often consider lineup fairness when comparing results across studies. Despite their importance, lineup fairness measures have received scant empirical attention and researchers inconsistently conduct and report mock-witness tasks and lineup fairness measures. We conducted a large-scale, online experiment (N = 1,010) to examine how lineup fairness measures varied with mock-witness task methodologies as well as to explore the validity and reliability of the measures. In comparison to descriptions compiled from multiple witnesses, when individual descriptions were presented in the mock-witness task, lineup fairness measures indicated a higher number of plausible lineup members but more bias toward the suspect. Target-absent lineups were consistently estimated to be fairer than target-present lineups-which is problematic because it suggests that lineups containing innocent suspects are less likely to be challenged in court than lineups containing guilty suspects. Correlations within lineup size measures and within some lineup bias measures indicated convergent validity and the correlations across the lineup size and lineup bias measures demonstrated discriminant validity. The reliability of lineup fairness measures across different descriptions was low and reliability across different sets of mock witnesses was moderate to high, depending on the measure. Researchers reporting lineup fairness measures should specify the type of description presented, the amount of detail in the description, and whether the mock witnesses viewed target-present and/or -absent lineups.

  20. Arterial spin labeling in combination with a look-locker sampling strategy: inflow turbo-sampling EPI-FAIR (ITS-FAIR).

    Günther, M; Bock, M; Schad, L R

    2001-11-01

    Arterial spin labeling (ASL) permits quantification of tissue perfusion without the use of MR contrast agents. With standard ASL techniques such as flow-sensitive alternating inversion recovery (FAIR) the signal from arterial blood is measured at a fixed inversion delay after magnetic labeling. As no image information is sampled during this delay, FAIR measurements are inefficient and time-consuming. In this work the FAIR preparation was combined with a Look-Locker acquisition to sample not one but a series of images after each labeling pulse. This new method allows monitoring of the temporal dynamics of blood inflow. To quantify perfusion, a theoretical model for the signal dynamics during the Look-Locker readout was developed and applied. Also, the imaging parameters of the new ITS-FAIR technique were optimized using an expression for the variance of the calculated perfusion. For the given scanner hardware the parameters were: temporal resolution 100 ms, 23 images, flip-angle 25.4 degrees. In a normal volunteer experiment with these parameters an average perfusion value of 48.2 +/- 12.1 ml/100 g/min was measured in the brain. With the ability to obtain ITS-FAIR time series with high temporal resolution arterial transit times in the range of -138 - 1054 ms were measured, where nonphysical negative values were found in voxels containing large vessels.

    How Darwinian evolution would produce creatures with the proclivity of Darwinian generosity, most of them voluntarily giving up the immediate benefit for themselves or their genes, remains a puzzle. This study targets a problem, the origin of human sense of fairness, and uses fairness-related genes and the social manipulation of Darwinian generosity as the key variables underlying the human sense of fairness, inequity aversion, as well as their relationships within cooperation, and the anticipation foresight of the way relationships are affected by resource division, given the assumption of randomly matched partners. Here we suggest a model in which phenotype will gradually converge towards the perfect sense of fairness along with the prospect of cooperation. Later, the sense of fairness will decrease but it is never extinct. Where social manipulation of Darwinian generosity overshadows genetics, the sense of fairness could be acute to the degree of social manipulation. Above all, there still exists a threshold in the degree of social manipulation, beyond which altruism dominates selfishness in human cooperation. Finally, we propose three new directions toward more realistic scenarios stimulated by recent development of the synergy between statistical physics, network science and evolutionary game theory.

    Drawing from the Deweyan theory of experience (1934, 1938), the goal of teaching and learning for transformative, aesthetic experience is contrasted against teaching and learning from a cognitive, rational framework. A quasi-experimental design was used to investigate teaching and learning of fifth grade science from each perspective across an entire school year including three major units of instruction. Detailed comparisons of teaching are given and pre and post measures of interest in learning science, science identity affiliation, and efficacy beliefs are investigated. Tests of conceptual understanding before, after, and one month after instruction reveal teaching for transformative, aesthetic experience fosters more, and more enduring, learning of science concepts. Investigations of transfer also suggest students learning for transformative, aesthetic experiences learn to see the world differently and find more interest and excitement in the world outside of school.

    To perform experiments in microgravity environment, there should be many difficulties compared with the experiments on ground. JAXA (Japan Aerospace Exploration Agency) has developed various experiment facilities to perform life science experiments in space, such as Cell Culture Kit, Thermo Electric Incubator, Free Flow Electrophoresis Unit, Aquatic Animal Experiment Unit, and so on. The first experiment facilities were flown on Spacelab-J mission in 1992, and they were improved and modified for the 2nd International Microgravity Laboratory (IML-2) mission in 1994. Based on these experiences, some of them were further improved and flown on another missions. These facilities are continuously being improved for the International Space Station use, where high level functions and automatic operations will be required.

  6. Exploring Aesthetic Experiences in the Undergraduate General Education Science Classroom

    NASA Astrophysics Data System (ADS)

    Biscotte, Stephen Michael

    Citizens must have a minimal level of STEM-literacy to work alongside scientists to tackle both current and future global challenges. How can general education, the one piece of the undergraduate experience every student completes, contribute to this development? And science learning is dependent on having transformative aesthetic experiences in the science classroom. These memorable experiences involve powerful connection between students and the world around them. If these types of experiences are necessary for science learning and growth, are students in introductory science courses having them? If so, what relationship might they have with students' desires to pursue further science study? This dissertation explores these questions through two manuscripts. The first, a theoretical piece published in the Journal of General Education in 2015, argues that non-STEM students must have transformative aesthetic experiences in their undergraduate general education science course to develop the level of understanding needed to engage with challenging scientific issues in the future. This claim is substantiated by bringing together the work of Dewey and Deweyan scholars on the nature and impact of aesthetic experiences in science and science education with the general education reform efforts and desired outcomes for an informed and engaged citizenry. The second manuscript, an empirical piece, explores the lived experience of non-STEM students in an introductory geosciences course. A phenomenological research methodology is deployed to capture the 'essence' of the lived experience of a STEM-philic student in general education science. In addition, Uhrmacher's CRISPA framework is used to analyze the participants' most memorable course moments for the presence or absence of aesthetic experiences. In explication of the data, it shows that students are in fact having aesthetic experiences (or connecting to prior aesthetic experiences) and these experiences are related to

    (Abstract only) New York City in the late 20th century rose to be a planetary capital for the sciences, not just astronomy. This growth was mainly in the academic sector but a parallel growth occurred in the public and home field. With the millennium crossing, scientists in New York agitated for a celebration of the City as a place for a thriving science culture. In 2008 they began World Science Festival. 2011 is the fourth running, on June 1-5, following the AAVSO/AAS meetings. World Science Festival was founded by Dr. Brian Greene, Columbia University, and is operated through the World Science Foundation. The Festival is "saturation science" all over Manhattan in a series of lectures, shows, exhibits, performances. It is staged in "science" venues like colleges and musea, but also in off-science spaces like theaters and galleries. It is a blend from hard science, with lectures like those by us astronomers, to science-themed works of art, dance, music. Events are fitted for the public, either for free or a modest fee.

    New York City in the late 20th century rose to be a planetary capital for the sciences, not just astronomy. This growth is mainly in the academic sector but a parallel growth occurred in the public and home field. With the millennium crossing scientists in New York agitated for a celebration of the City as a place for a thriving science culture. In 2008 they began World Science Festival. 2011 is the fourth running, on June 1st-5th, following AAVSO/AAS. World Science Festival was founded by Dr Brian Greene, Columbia University, and is operated thru World Science Foundation. The Festival is 'saturation science' all over Manhattan in a series of lectures, shows, exhibits, performances. It is staged in 'science' venues like colleges and musea, but also in off-science spaces like theaters and galleries. It is a blend of hard science, with lectures like those by us astronomers to science-themed works of art, dance, music. Events are fitted for the public, either for free or a modest fee. While almost all events are on Manhattan, effort is done to geographicly disperse them, even to the outer boros. The grand finale of World Science Festival is a street fair in Washington Square. Science centers in booths, tents, pavilions highlight their work. This fair drew in past years 100,000 to 150,000 visitors. The entire Festival attracts about a quarter million. NYSkies is a proud participant at the Washington Square fair. It interprets the 'Earth to the Universe' display, debuting during IYA-2009.

    The present paper describes an experience of science theatre addressed to children of primary and secondary school, with the main purpose of explaining the Earth interior while raising awareness about natural hazard. We conducted the experience with the help of a theatrical company specialized in shows for children. Several performances have been reiterated in different context, giving us the opportunity of conducting a preliminary survey with public of different ages, even if the show was conceived for children. Results suggest that science theatre while relying on creativity and emotional learning in transmitting knowledge about the Earth and its hazard has the potential to induce in children a positive attitude towards the risks

  10. Cooperating when "you" and "I" are treated fairly: the moderating role of leader prototypicality.

    De Cremer, David; van Dijke, Marius; Mayer, David M

    2010-11-01

    We developed a model predicting that leaders are most effective in stimulating follower cooperation when they consistently treat all group members in a fair manner and are prototypical (i.e., representative of the group's values and norms). In support of this idea, we consistently found that group members cooperated most when prototypical leaders treated themselves as well as their coworkers fairly across a laboratory experiment and 3 cross-sectional field studies. These findings highlight the important role of others' fairness experiences and perceptions in influencing one's own reactions and also the role of leaders as representing the group's values and norms. We discuss implications for fairness theory and the leader prototypicality literature. (c) 2010 APA, all rights reserved.

  14. School Teachers' Experiences of Science Curriculum Reform

    NASA Astrophysics Data System (ADS)

    Ryder, Jim; Banner, Indira

    2013-02-01

    We examine teachers' experiences of a major reform of the school science curriculum for 14-16-year olds in England. This statutory reform enhances the range of available science courses and emphasises the teaching of socio-scientific issues and the nature of science, alongside the teaching of canonical science knowledge. This paper examines teachers' experiences of the reform and the factors that condition these experiences. A designed sample of 22 teachers discussed their experiences of the reform within a semi-structured interview. Our analysis considers how the external and internal structures within which teachers work interact with the personal characteristics of teachers to condition their experiences of the curriculum reform. In many cases, personal/internal/external contexts of teachers' work align, resulting in an overall working context that is supportive of teacher change. However, in other cases, tensions within these contexts result in barriers to change. We also explore cases in which external curriculum reform has stimulated the development of new contexts for teachers' work. We argue that curriculum reformers need to recognise the inevitability of multiple teaching goals within a highly differentiated department and school workplace. We also show how experiences of curriculum reform can extend beyond the learning of new knowledge and associated pedagogies to involve challenges to teachers' professional identities. We argue for the extended use of teacher role models within local communities of practice to support such 'identity work'.

    Our research ecosystem is diverse and dependent on many interacting stakeholders that influence and support the process of science. These include funders, institutions, libraries, publishers, researchers, data managers, repositories, archives and communities. Process improvement in this ecosystem thus usually needs support by more than one of these many stakeholders. For example, mandates for open data extend across this ecosystem. Solutions require these stakeholders to come together and agree upon improvements. Recently, the value of FAIR and Open Data has encouraged funders to sponsor discussions with tangible agreements that include the steps needed to move the ecosystem towards results. Work by many of these stakeholders over the past years have developed pilot efforts that are ready to be scaled with broader engagement. A partnership of the AGU, Earth Science Information Partners (ESIP), Research Data Alliance (RDA), Center for Open Science, and key publishers including Science, Nature, and the Proceedings of the National Academy of Science (PNAS) have agreed to work together to develop integrated processes, leveraging these pilots, to make FAIR and open data the default for Earth and space science publications. This effort will build on the work of COPDESS.org, ESIP, RDA, the scientific journals, and domain repositories to ensure that well documented data, preserved in a repository with community agreed-upon metadata, and supporting persistent identifiers becomes part of the expected research products submitted in support of each publication.

  17. How fair is access to more prestigious UK universities?

    PubMed

    Boliver, Vikki

    2013-06-01

    Now that most UK universities have increased their tuition fees to £9,000 a year and are implementing new Access Agreements as required by the Office for Fair Access, it has never been more important to examine the extent of fair access to UK higher education and to more prestigious UK universities in particular. This paper uses Universities and Colleges Admissions Service (UCAS) data for the period 1996 to 2006 to explore the extent of fair access to prestigious Russell Group universities, where 'fair' is taken to mean equal rates of making applications to and receiving offers of admission from these universities on the part of those who are equally qualified to enter them. The empirical findings show that access to Russell Group universities is far from fair in this sense and that little changed following the introduction of tuition fees in 1998 and their initial increase to £3,000 a year in 2006. Throughout this period, UCAS applicants from lower class backgrounds and from state schools remained much less likely to apply to Russell Group universities than their comparably qualified counterparts from higher class backgrounds and private schools, while Russell Group applicants from state schools and from Black and Asian ethnic backgrounds remained much less likely to receive offers of admission from Russell Group universities in comparison with their equivalently qualified peers from private schools and the White ethnic group. © London School of Economics and Political Science 2013.

  19. Fair Package Assignment

    NASA Astrophysics Data System (ADS)

    Lahaie, Sébastien; Parkes, David C.

    We consider the problem of fair allocation in the package assignment model, where a set of indivisible items, held by single seller, must be efficiently allocated to agents with quasi-linear utilities. A fair assignment is one that is efficient and envy-free. We consider a model where bidders have superadditive valuations, meaning that items are pure complements. Our central result is that core outcomes are fair and even coalition-fair over this domain, while fair distributions may not even exist for general valuations. Of relevance to auction design, we also establish that the core is equivalent to the set of anonymous-price competitive equilibria, and that superadditive valuations are a maximal domain that guarantees the existence of anonymous-price competitive equilibrium. Our results are analogs of core equivalence results for linear prices in the standard assignment model, and for nonlinear, non-anonymous prices in the package assignment model with general valuations.

  3. Hypernuclear physics studies of the P̅ANDA experiment at FAIR

    Sanchez Lorente, Alicia

    2015-05-01

    Hypernuclear research will be one of the main topics addressed by the PANDA experiment at the planned Facility for Antiproton and Ion Research FAIR at Darmstadt (Germany). [1, 2] Thanks to the use of stored p̅ beams, copious production of double Λ hypernuclei is expected at the PANDA experiment, which will enable high precision γ spectroscopy of such nuclei for the first time, and consequently a unique chance to explore the hyperon-hyperon interaction. In particular, ambiguities of past experiments in determining the strength of the ΛΛ interaction will be avoided thanks to the excellent energy precision of a few keV (FWHM) achieved by germanium detectors. Such a resolution capability is particularly needed to resolve the small energy spacing of the order of (10-100) keV, which is characteristic from the spin doublet in hypernuclei the so -called "hypernuclear fine structure". In comparison to previous experiments, PANDA will benefit from a novel technique to assign the various observable γ-transitions in a unique way to specific double hypernuclei by exploring various light targets. Nevertheless, the ability to carry out unique assignments requires a devoted hypernuclear detector setup. This consists of a primary nuclear target for the production of Ξ- + overline Xi pairs, a secondary active target for the hypernuclei formation and the identification of associated decay products and a germanium array detector to perform γ spectroscopy. Moreover, one of the most challenging issues of this project is the fact that all detector systems need to operate in the presence of a high magnetic field and a large hadronic background. Accordingly, the need of an innovative detector concept will require dramatic improvements to fulfil these conditions and that will likely lead to a new generation of detectors. In the present work details concerning the current status of the activities related to the detector developments for this challenging programme will be given. Among

    A vehicle underbody fairing apparatus for reducing aerodynamic drag caused by a vehicle wheel assembly, by reducing the size of a recirculation zone formed under the vehicle body immediately downstream of the vehicle wheel assembly. The fairing body has a tapered aerodynamic surface that extends from a front end to a rear end of the fairing body with a substantially U-shaped cross-section that tapers in both height and width. Fasteners or other mounting devices secure the fairing body to an underside surface of the vehicle body, so that the front end is immediately downstream of the vehicle wheel assembly and a bottom section of the tapered aerodynamic surface rises towards the underside surface as it extends in a downstream direction.

  10. The Roles of Aesthetic Experience in Elementary School Science

    NASA Astrophysics Data System (ADS)

    Jakobson, Britt; Wickman, Per-Olof

    2008-01-01

    The role of aesthetic experiences for learning was examined in elementary school science. Numerous authors have argued for a science education also involving aesthetic experiences, but few have examined what this means empirically. Recordings of children’s talk with each other and with the teacher during hands-on activities in nine different science units were made. How the children and teachers used aesthetic judgements and how these judgements were part of aesthetic experiences of the science assignments were analysed. For the analysis a pragmatist perspective was used, especially drawing on Dewey and the later Wittgenstein. The results showed how aesthetic judgements occurred in moments of anticipation and moments when the science activities were brought to fulfilment. In this way children used aesthetic judgements normatively about what belonged in science class and what to include and exclude. In this way aesthetic judgements were an important part of learning how to proceed in science class. In using aesthetic judgements the children also talked about their own place in science class and whether they belonged there or not. In this way aesthetic experience is tightly related to learning science as participation. Learning science also meant learning a special kind of aesthetics, that is, learning how to distinguish the science context from other contexts. The fact that children liked or disliked something outside school did not necessarily mean that it was experienced aesthetically in the same way in school, but needed to be re-learnt. What these results mean for science education is discussed at length. The connection between aesthetics and learning to observe is also briefly discussed.

    High-energy heavy-ion collision experiments provide the unique possibility to create and investigate extreme states of strongly-interacted matter and address the fundamental aspects of QCD. The experimental investigation the QCD phase diagram would be a major breakthrough in our understanding of the properties of nuclear matter. The reconstruction of the charged particles created in the nuclear collisions, including the determination of their momenta, is the central detection task in high-energy heavy-ion experiments. It is taken up by the Silicon Tracking System in CBM@FAIR and by Inner Tracker in MPD@NICA currently under development. These experiments requires very fast and radiation hard detectors, a novel data read-out and analysis concept including free streaming front-end electronics. Thermal and beam tests of prototype detector modules for these tracking systems showed the stability of sensors and readout electronics operation.

  13. Computational Experiments for Science and Engineering Education

    Xie, Charles

    2011-01-01

    How to integrate simulation-based engineering and science (SBES) into the science curriculum smoothly is a challenging question. For the importance of SBES to be appreciated, the core value of simulations-that they help people understand natural phenomena and solve engineering problems-must be taught. A strategy to achieve this goal is to introduce computational experiments to the science curriculum to replace or supplement textbook illustrations and exercises and to complement or frame hands-on or wet lab experiments. In this way, students will have an opportunity to learn about SBES without compromising other learning goals required by the standards and teachers will welcome these tools as they strengthen what they are already teaching. This paper demonstrates this idea using a number of examples in physics, chemistry, and engineering. These exemplary computational experiments show that it is possible to create a curriculum that is both deeper and wider.

    Meet Jonathan and Elizabeth. One person is a doctor and the other is a nurse. Who is the doctor? When nothing else is known, the base rate principle favors Jonathan to be the doctor and the fairness principle favors both individuals equally. However, when individuating facts reveal who is actually the doctor, base rates and fairness become irrelevant, as the facts make the correct answer clear. In three experiments, explicit and implicit beliefs were measured before and after individuating facts were learned. These facts were either stereotypic (e.g., Jonathan is the doctor, Elizabeth is the nurse) or counterstereotypic (e.g., Elizabeth is the doctor, Jonathan is the nurse). Results showed that before individuating facts were learned, explicit beliefs followed the fairness principle, whereas implicit beliefs followed the base rate principle. After individuating facts were learned, explicit beliefs correctly aligned with stereotypic and counterstereotypic facts. Implicit beliefs, however, were immune to counterstereotypic facts and continued to follow the base rate principle. Having established the robustness and generality of these results, a fourth experiment verified that gender stereotypes played a causal role: when both individuals were male, explicit and implicit beliefs alike correctly converged with individuating facts. Taken together, these experiments demonstrate that explicit beliefs uphold fairness and incorporate obvious and relevant facts, but implicit beliefs uphold base rates and appear relatively impervious to counterstereotypic facts.

  18. Science Experiences among Female Athletes: Race Makes a Difference

    NASA Astrophysics Data System (ADS)

    Kraus, Rebecca S.; Hanson, Sandra L.

    Sport participation is increasingly seen as a resource with considerable physical, social, and academic benefits. As a new millennium begins with girls more visible in sport, an important question is whether all girls reap these benefits. Although general academic benefits of sport have been shown, the authors' earlier work showed that experience in the male sport domain benefits young women in the elite (often male) science curriculum. Competition, self-esteem, and other individual resources gained through sport are potential sources of success in the similarly competitive male realm of science. In this research, the authors used critical feminist theory to guide their examination of racial and ethnic variations in the relation between sport participation and science experiences for young women. Data from the nationally representative National Education Longitudinal Study were used to explore the impact of sport participation in the 8th and 10th grades on 10th grade science achievement (measured by science grades and standardized test scores) and course taking for African American, Hispanic, and White women. The findings revealed that sport participation has some positive consequences for the science experiences of each of the groups of women. It also has some negative consequences, although the positive consequences outnumber the negative consequences for Hispanic and White, but not African American, women. Sport in 10th grade, especially competitive varsity sport, is most likely to have positive consequences. The findings revealed that each of the groups experiences different routes to success in science, and sport participation is present at some level in each of these routes. A consideration of multiple areas of science experience is important for understanding the connections between race and ethnicity, sport, and science for young women. Unique sociocultural contexts are used to attempt to understand these findings, and implications are discussed.

  19. Investigating minority student participation in an authentic science research experience

    NASA Astrophysics Data System (ADS)

    Preston, Stephanie Danette

    In the United States, a problem previously overlooked in increasing the total number of scientifically literate citizens is the lack of diversity in advanced science classes and in science, technology, engineering, and mathematics (STEM) fields. Groups traditionally underserved in science education and thus underrepresented in the STEM fields include: low-income, racial/ethnic minorities, and females of all ethnic and racial backgrounds. Despite the number of these students who are initially interested in science very few of them thrive in the discipline. Some scholars suggest that the declining interest for students underrepresented in science is traceable to K-12th grade learning experiences and access to participating in authentic science. Consequently, the diminishing interest of minorities and women in science contributes negatively to the representation of these groups in the STEM disciplines. The purpose of this study was to investigate a summer science research experience for minority students and the nature of students' participation in scientific discourse and practices within the context of the research experience. The research questions that guided this study are: The nature of the Summer Experience in Earth and Mineral Science (SEEMS) research experience . (A) What are the SEEMS intended outcomes? (B) To what extent does SEEMS enacted curriculum align with the intended outcomes of the program? The nature of students engagement in the SEEMS research. (A) In what ways do students make sense of and apply science concepts as they engage in the research (e.g., understand problem, how they interpret data, how they construct explanations), and the extent to which they use the science content appropriately? (B) In what ways do students engage in the cultural practices of science, such as using scientific discourse, interpreting inscriptions, and constructing explanations from evidence (engaging in science practices, knowing science and doing science)?

    The rapid expansion of remote sensing capability over the last two decades will take another major leap forward with the advent of the Earth Observing System (Eos). An approach is presented that will permit experiments and demonstrations in onboard information extraction. The approach is a non-intrusive, eavesdropping mode in which a small amount of spacecraft real estate is allocated to an onboard computation resource. How such an approach allows the evaluation of advanced technology in the space environment, advanced techniques in information extraction for both Earth science and information science studies, direct to user data products, and real-time response to events, all without affecting other on-board instrumentation is discussed.

The current study investigated whether 15-month-old infants select social partners on the basis of prior fair versus unfair behavior, and whether infants integrate social selections on the basis of fairness with the race of the distributors and recipients involved in the exchange. Experiment 1 demonstrated that after witnessing one adult distribute toys to two recipients fairly (2:2 distribution), and another adult distribute toys to two recipients unfairly (1:3 distribution), Caucasian infants selected fair over unfair distributors when both distributors were Caucasian; however, this preference was not present when the fair actor was Asian and the unfair actor was Caucasian. In Experiment 2, when fairness, the race of the distributor, and the race of the recipients were fully crossed, Caucasian infants’ social selections varied as a function of the race of the recipient advantaged by the unfair distributor. Specifically, infants were more likely to select the fair distributor when the unfair recipient advantaged the Asian (versus the Caucasian) recipient. These findings provide evidence that infants select social partners on the basis of prior fair behavior and that infants also take into account the race of distributors and recipients when making their social selections.

    Having diverse faculty in academic health centers will help diversify the healthcare workforce and reduce health disparities. Implicit race bias is one factor that contributes to the underrepresentation of Black faculty. We designed the videogame "Fair Play" in which players assume the role of a Black graduate student named Jamal Davis. As Jamal, players experience subtle race bias while completing "quests" to obtain a science degree. We hypothesized that participants randomly assigned to play the game would have greater empathy for Jamal and lower implicit race bias than participants randomized to read narrative text describing Jamal's experience. University of Wisconsin-Madison graduate students were recruited via e-mail and randomly assigned to play "Fair Play" or read narrative text through an online link. Upon completion, participants took an Implicit Association Test to measure implicit bias and answered survey questions assessing empathy toward Jamal and awareness of bias. As hypothesized, gameplayers showed the least implicit bias but only when they also showed high empathy for Jamal (P=0.013). Gameplayers did not show greater empathy than text readers, and women in the text condition reported the greatest empathy for Jamal (P=0.008). However, high empathy only predicted lower levels of implicit bias among those who actively took Jamal's perspective through gameplay (P=0.014). A videogame in which players experience subtle race bias as a Black graduate student has the potential to reduce implicit bias, possibly because of a game's ability to foster empathy through active perspective taking.

  3. A New TCP Congestion Control Supporting RTT-Fairness

    This paper focuses on RTT-fairness of multiple TCP flows over the Internet, and proposes a new TCP congestion control named “HRF (Hybrid RTT-Fair)-TCP”. Today, it is a serious problem that the flows having smaller RTT utilize more bandwidth than others when multiple flows having different RTT values compete in the same network. This means that a user with longer RTT may not be able to obtain sufficient bandwidth by the current methods. This RTT fairness issue has been discussed in many TCP papers. An example is CR (Constant Rate) algorithm, which achieves RTT-fairness by multiplying the square of RTT value in its window increment phase against TCP-Reno. However, the method halves its windows size same as TCP-Reno when a packet loss is detected. This makes worse its efficiency in certain network cases. On the other hand, recent proposed TCP versions essentially require throughput efficiency and TCP-friendliness with TCP-Reno. Therefore, we try to keep these advantages in our TCP design in addition to RTT-fairness. In this paper, we make intuitive analytical models in which we separate resource utilization processes into two cases: utilization of bottleneck link capacity and that of buffer space at the bottleneck link router. These models take into account three characteristic algorithms (Reno, Constant Rate, Constant Increase) in window increment phase where a sender receives an acknowledgement successfully. Their validity is proved by both simulations and implementations. From these analyses, we propose HRF-TCP which switches two modes according to observed RTT values and achieves RTT fairness. Experiments are carried out to validate the proposed method. Finally, HRF-TCP outperforms conventional methods in RTT-fairness, efficiency and friendliness with TCP-Reno.

  5. Balancing the Fair Treatment of Others While Preserving Group Identity and Autonomy.

    Social exclusion and inclusion from groups, as well as the distribution of resources, are fundamental aspects of social life, and serve as sources of conflicts that bear on issues of fairness and equality, beginning in childhood. For the most part, research on social exclusion and allocation of resources has not focused on the issue of group membership. Yet, social exclusion from groups and the denial of resources reflect societal issues pertaining to social inequality and its counterpoint, fair treatment of others. Social inequality occurs when opportunities and resources are distributed unevenly in society, often through group norms about allocation that reflect socially defined categories of persons. This occurs at multiple levels of societal organization, from experiences of exclusion in childhood such as being left out of a play activity, to being denied access to resources as a member of a group. These situations extend to larger level experiences in the adult world concerning social exclusion from voting, for example, or participation in educational institutions. Thus, most decisions regarding social exclusion and the denial of resources involve considerations of group identity and group membership, implicitly or explicitly, which contribute to prejudice and bias, even though this has rarely been investigated in developmental science. Current research illustrating the role of group identity and autonomy regarding decision-making about social exclusion and the denial of resources is reviewed from the Social Reasoning Developmental model, one that integrates social domain theory and developmental social identity theories to investigate how children use moral, conventional, and psychological judgments to evaluate contexts reflecting group identity, group norms, and intergroup dynamics.

    Can adults make fair moral judgments when individuals with whom they have different relationships are involved? The present study explored the fairness of adults’ relationship-based moral judgments in two respects by performing three experiments involving 999 participants. In Experiment 1, 65 adults were asked to decide whether to harm a specific person to save five strangers in the footbridge and trolley dilemmas in a within-subject design. The lone potential victim was a relative, a best friend, a person they disliked, a criminal or a stranger. Adults’ genetic relatedness to, familiarity with and affective relatedness to the lone potential victims varied. The results indicated that adults made different moral judgments involving the lone potential victims with whom they had different relationships. In Experiment 2, 306 adults responded to the footbridge and trolley dilemmas involving five types of lone potential victims in a within-subject design, and the extent to which they were familiar with and affectively related to the lone potential victim was measured. The results generally replicated those of Experiment 1. In addition, for close individuals, adults’ moral judgments were less deontological relative to their familiarity with or positive affect toward these individuals. For individuals they were not close to, adults made deontological choices to a larger extent relative to their unfamiliarity with or negative affect toward these individuals. Moreover, for familiar individuals, the extent to which adults made deontological moral judgments more closely approximated the extent to which they were familiar with the individual. The adults’ deontological moral judgments involving unfamiliar individuals more closely approximated their affective relatedness to the individuals. In Experiment 3, 628 adults were asked to make moral judgments with the type of lone potential victim as the between-subject variable. The results generally replicated those of the

  7. Teacher research experiences, epistemology, and student attitudes toward science

    Payne, Diana L.

    This concurrent mixed methods research study examined the impact of a Teacher Research Experience (TRE) on science teacher beliefs about science, scientific research, science teaching, and student attitudes toward science. Surveys, interviews, reflective journals, and classroom observations of six teachers involved in a TRE were utilized to examine changes in beliefs as a result of participation in the TRE. Student attitudes were measured with a pre and post survey. An analysis of qualitative data from the teachers' interviews, journals, and pre and post TRE surveys indicated that some change occurred in their beliefs about science and scientists for all six teachers, and that teachers' beliefs about science teaching were affected in a variety of ways after participating in the TRE. The quantitative results of the study using Science Teachers' Beliefs About Science (STBAS) instrument suggest that the change from the beginning to the end of the school year, if any, was minimal. However, interviews with and observations of teachers identified valuable components of the TRE, such as the advanced resources (e.g., DVD, samples), a feeling of rejuvenation in teaching, a new perspective on science and scientific research, and first hand experiences in science. Results from the classroom observations using the Science Classroom Practice Record (SCPR) were mixed. Some differences may be explained, however, as relating to content taught in the pre and post classes observed or simply to inherent differences in student dynamics and behavior from class to class. There were no significant differences from pre to post TRE regarding student attitudes toward science as measured by paired samples t-tests on the modified Attitudes Toward Science (mATSI) instrument. Attitudes and beliefs are not easily changed, and change is more likely to result from direct experience and education rather than an indirect experience. Although the results are generalizable only to the participants in

    The future FAIR experiments CBM and PANDA have computing requirements that fall in a category that could currently not be satisfied by one single computing centre. One needs a larger, distributed computing infrastructure to cope with the amount of data to be simulated and analysed. Since 2002, GSI operates a tier2 center for ALICE@CERN. The central component of the GSI computing facility and hence the core of the ALICE tier2 centre is a LSF/SGE batch farm, currently split into three subclusters with a total of 15000 CPU cores shared by the participating experiments, and accessible both locally and soon also completely via Grid. In terms of data storage, a 5.5 PB Lustre file system, directly accessible from all worker nodes is maintained, as well as a 300 TB xrootd-based Grid storage element. Based on this existing expertise, and utilising ALICE's middleware ‘AliEn’, the Grid infrastructure for PANDA and CBM is being built. Besides a tier0 centre at GSI, the computing Grids of the two FAIR collaborations encompass now more than 17 sites in 11 countries and are constantly expanding. The operation of the distributed FAIR computing infrastructure benefits significantly from the experience gained with the ALICE tier2 centre. A close collaboration between ALICE Offline and FAIR provides mutual advantages. The employment of a common Grid middleware as well as compatible simulation and analysis software frameworks ensure significant synergy effects.

  10. Negative incidental emotions augment fairness sensitivity.

    2016-04-22

    Previous studies have shown that task-unrelated emotions induced incidentally exert carryover effects on individuals' subsequent decisions in financial negotiations. However, the specificity of these emotion effects are not clear. In three experiments, we systematically investigated the role of seven transiently induced basic emotions (disgust, sadness, anger, fear, happiness, surprise and neutral) on rejection of unfair offers using the ultimatum game. We found that all negative emotions (disgust, sadness, anger and fear), but not happiness or surprise, significantly increased rejection rates, suggesting that the effect of incidental negative emotions on fairness is not specific to the type of negative emotion. Our findings highlight the role of fleeting emotions in biasing decision-making processes and suggest that all incidental negative emotions exert similar effects on fairness sensitivity, possibly by potentiating attention towards negative aspects of the situation.

  13. Fairness, fast and slow: A review of dual process models of fairness.

    PubMed

    Hallsson, Bjørn G; Siebner, Hartwig R; Hulme, Oliver J

    2018-06-01

    Fairness, the notion that people deserve or have rights to certain resources or kinds of treatment, is a fundamental dimension of moral cognition. Drawing on recent evidence from economics, psychology, and neuroscience, we ask whether self-interest is always intuitive, requiring self-control to override with reasoning-based fairness concerns, or whether fairness itself can be intuitive. While we find strong support for rejecting the notion that self-interest is always intuitive, the literature has reached conflicting conclusions about the neurocognitive systems underpinning fairness. We propose that this disagreement can largely be resolved in light of an extended Social Heuristics Hypothesis. Divergent findings may be attributed to the interpretation of behavioral effects of ego depletion or neurostimulation, reverse inference from brain activity to the underlying psychological process, and insensitivity to social context and inter-individual differences. To better dissect the neurobiological basis of fairness, we outline how future research should embrace cross-disciplinary methods that combine psychological manipulations with neuroimaging, and that can probe inter-individual, and cultural heterogeneities.

    2006-08-01

    This paper explores the science-related interests and out-of-school experiences of 583 ninth-grade Greek students. The instrument of data collection consisted of a questionnaire including items on science-related topics that could be of interest to students and on everyday, out-of-school, science-related experiences. Factor analysis yielded six distinct fields of interest and five types of science-related experiences. Significant gender differences emerge: girls are more interested in topics related to human biology, health, and fitness, and are more familiar with using instruments and devices, seeking information about nature, and doing cuisine and handicraft; while boys are more interested in science, technology, and their social dimension, and the threatening aspects of science and technology, and tend to engage more in manual work and computer use. The results of this study indicate that there is a need for the Greek science curriculum to become more appealing to students, by integrating topics and experiences that are interesting and relevant to them.

    1987-07-01

    Individual differences in judgments of the fairness of various sociopolitical phenomena were examined in three surveys. Scales measuring two value dimensions thought to underlie the meaning of fairness were constructed, and survey respondents endorsing these different values were compared on their evaluation of the procedural and distributive fairness of political objects. Those endorsing the value of proportionality, hypothesized by equity theorists to underlie fairness judgments, judged equity-based public policies to be fairer than equality-based policies and judged that Ronald Reagan would be a fairer president than Walter Mondale. These people also emphasized the procedural aspects of government when judging government fairness. Respondents endorsing the value of egalitarianism, hypothesized by developmental theorists and some political philosophers to underlie fairness judgments, judged equality-based public policies to be fairer than equity-based policies and judged that Mondale would be a fairer president than Reagan. These people emphasized the distributive aspects of government when judging government fairness. Results support the naive moral philosopher image of the individual as judge of political objects (Tyler, 1984a). Political fairness judgments are ideological responses and are subject to the influence of the value structure of the judge (Tetlock, 1986).

  20. Architecting Learning Continuities for Families Across Informal Science Experiences

    NASA Astrophysics Data System (ADS)

    Perin, Suzanne Marie

    By first recognizing the valuable social and scientific practices taking place within families as they learn science together across multiple, everyday settings, this dissertation addresses questions of how to design and scaffold activities that build and expand on those practices to foster a deep understanding of science, and how the aesthetic experience of learning science builds connections across educational settings. Families were invited to visit a natural history museum, an aquarium, and a place or activity of the family's choice that they associated with science learning. Some families were asked to use a set of activities during their study visits based on the practices of science (National Research Council, 2012), which were delivered via smartphone app or on paper cards. I use design-based research, video data analysis and interaction analysis to examine how families build connections between informal science learning settings. Chapter 2 outlines the research-based design process of creating activities for families that fostered connections across multiple learning settings, regardless of the topical content of those settings. Implications of this study point to means for linking everyday family social practices such as questioning, observing, and disagreeing to the practices of science through activities that are not site-specific. The next paper delves into aesthetic experience of science learning, and I use video interaction analysis and linguistic analysis to show how notions of beauty and pleasure (and their opposites) are perfused throughout learning activity. Designing for aesthetic experience overtly -- building on the sensations of enjoyment and pleasure in the learning experience -- can motivate those who might feel alienated by the common conception of science as merely a dispassionate assembly of facts, discrete procedures or inaccessible theory.

    Alaska's secondary school teachers are increasingly required to provide Earth systems science (ESS) education that integrates student observations of local natural processes related to rapid climate change with geospatial datasets and satellite imagery using Geographic Information Systems (GIS) technology. Such skills are also valued in various employment sectors of the state where job opportunities requiring Earth science and GIS training are increasing. University of Alaska's EDGE (Experiential Discoveries in Geoscience Education) program has provided training and classroom resources for 3 cohorts of inservice Alaska science and math teachers in GIS and Earth Systems Science (2005-2007). Summer workshops include geologic field experiences, GIS instruction, computer equipment and technical support for groups of Alaska high school (HS) and middle school (MS) science teachers each June and their students in August. Since 2005, EDGE has increased Alaska science and math teachers' Earth science content knowledge and developed their GIS and computer skills. In addition, EDGE has guided teachers using a follow-up, fall online course that provided more extensive ESS knowledge linked with classroom standards and provided course content that was directly transferable into their MS and HS science classrooms. EDGE teachers were mentored by University faculty and technical staff as they guided their own students through semester-scale, science fair style projects using geospatial data that was student- collected. EDGE program assessment indicates that all teachers have improved their ESS knowledge, GIS knowledge, and the use of technology in their classrooms. More than 230 middle school students have learned GIS, from EDGE teachers and 50 EDGE secondary students have conducted original research related to landscape change and its impacts on their own communities. Longer-term EDGE goals include improving student performance on the newly implemented (spring 2008) 10th grade

    The present study examined the reliability of student evaluations of summer undergraduate research experiences using the SURE (Survey of Undergraduate Research Experiences) and a follow-up survey disseminated 9 mo later. The survey further examines the hypothesis that undergraduate research enhances the educational experience of science undergraduates, attracts and retains talented students to careers in science, and acts as a pathway for minority students into science careers. Undergraduates participated in an online survey on the benefits of undergraduate research experiences. Participants indicated gains on 20 potential benefits and reported on career plans. Most of the participants began or continued to plan for postgraduate education in the sciences. A small group of students who discontinued their plans for postgraduate science education reported significantly lower gains than continuing students. Women and men reported similar levels of benefits and similar patterns of career plans. Undergraduate researchers from underrepresented groups reported higher learning gains than comparison students. The results replicated previously reported data from this survey. The follow-up survey indicated that students reported gains in independence, intrinsic motivation to learn, and active participation in courses taken after the summer undergraduate research experience.

    2013-01-01

    The current study explored whether earned entitlement modulated the perception of fairness in three experiments. A preliminary resource earning task was added before players decided how to allocate the resource they jointly earned. Participants’ decision in allocation, their responses to equal or unequal offers, whether advantageous or disadvantageous, and subjective ratings of fairness were all assessed in the current study. Behavioral results revealed that participants proposed more generous offers and showed enhanced tolerance to disadvantageous unequal offers from others when they performed worse than their presumed “partners,” while the reverse was true in the better-performance condition. The subjective ratings also indicated the effect of earned entitlement, such that worse performance was associated with higher perceived feelings of fairness for disadvantageous unequal offers, while better performance was associated with higher feelings of fairness for advantageous unequal offers. Equal offers were considered “fair” only when earned entitlement was even between two parties. In sum, the perception of fairness is modulated by an integration of egalitarian motivation and entitlement. In addition to justice principles, participants were also motivated by self-interest, such that participants placed more weight on entitlement in the better-performance condition than in the worse-performance condition. These results imply that earned entitlement is evaluated in a self-serving way. PMID:24039867

    The author defends himself against an attack by Smith and Bopp on his views on smoking and taxation. The theory that, on the grounds of equity and/or fairness, smokers should pay via taxation on tobacco for the health care costs of treating smoking-related medical conditions is discussed and shown to be defective. It is argued that the fundamental mistake that Smith and Bopp make is to confuse and conflate the separate issues of whether particular taxes are fair and whether they are justifiable. The conclusion is reached that an excise duty on tobacco is a good tax. It is a non-fair or even an unfair tax but it is justified on grounds other than fairness. PMID:12468659

    This study asserts that science is contextualized and should therefore be taught as contextualized. Works of major philosophers in 20th century history, philosophy and sociology of science and recent developments in cognition are discussed in developing a foundation and outlining three themes for contextualized science: (a) science curriculum should emphasize scientific methodology through the generation and testing of knowledge in a specific context, (b) it should validate and evaluate everyday contextual experiences, and (c) develop a context for action by engaging in science, technology and society issues. School science is a major instrument for diffusion and utilization of scientific knowledge. In India, textbooks are often the only classroom source of information for students other than the teacher. The most widely used standard curriculum materials in Indian schools are the National Council of Educational Research and Training (NCERT) textbooks. For schools in the Hoshingabad district of Madhya Pradesh, the state prescribes NCERT materials and materials developed for the Hoshingabad Science Teaching Program (HSTP), a grassroots science education initiative. In this study, the investigation of these curriculum materials and interviews with educators (curriculum developers/textbook authors/teachers at New Delhi and Hoshingabad) are used to establish criteria for both the need and the feasibility of contextualized science. Results of the investigation indicate that the centralized NCERT system of curriculum development has undermined context specific treatment of subject matter in their textbooks. While HSTP attempted to contextualize science in rural schools, the present status of the program may be interpreted as either development and legitimization of another standardized curriculum, or, as the culmination of a gradual erosion and dissipation of conceptually valid and concrete educational practices. There are major situational and institutional constraints

    Since the Cambridge Science Festival launched in 2007, communities across the United States have experimented with the science festival format, working out what it means to celebrate science and technology. What have we learned, and where might we go from here? The Science Festival Alliance has supported and tracked developments among U.S. festivals, and this presentation will present key findings from three years of independent evaluation. While science festivals have coalesced into a distinct category of outreach activity, the diversity of science festival initiatives reflects the unique character of the regions in which the festivals are organized. This symposium will consider how festivals generate innovative public programming by adapting to local conditions and spur further innovation by sharing insights into such adaptations with other festivals. With over 55 annual large scale science festivals in the US alone, we will discuss the implications of a dramatic increase in future festival activity.

The physics program of the CBM experiment is complimentary to the programs to be realized at MPD and BMN facilities at NICA and will start with beam derived by the SIS100 synchrotron. The results of JINR participation in the development of different sub-projects of the CBM experiment are presented.

  13. Balancing the Fair Treatment of Others While Preserving Group Identity and Autonomy

    2016-01-01

    Social exclusion and inclusion from groups, as well as the distribution of resources, are fundamental aspects of social life, and serve as sources of conflicts that bear on issues of fairness and equality, beginning in childhood. For the most part, research on social exclusion and allocation of resources has not focused on the issue of group membership. Yet, social exclusion from groups and the denial of resources reflect societal issues pertaining to social inequality and its counterpoint, fair treatment of others. Social inequality occurs when opportunities and resources are distributed unevenly in society, often through group norms about allocation that reflect socially defined categories of persons. This occurs at multiple levels of societal organization, from experiences of exclusion in childhood such as being left out of a play activity, to being denied access to resources as a member of a group. These situations extend to larger level experiences in the adult world concerning social exclusion from voting, for example, or participation in educational institutions. Thus, most decisions regarding social exclusion and the denial of resources involve considerations of group identity and group membership, implicitly or explicitly, which contribute to prejudice and bias, even though this has rarely been investigated in developmental science. Current research illustrating the role of group identity and autonomy regarding decision-making about social exclusion and the denial of resources is reviewed from the Social Reasoning Developmental model, one that integrates social domain theory and developmental social identity theories to investigate how children use moral, conventional, and psychological judgments to evaluate contexts reflecting group identity, group norms, and intergroup dynamics.

    The scientific objectives of the Giotto Radio Science Experiment (GRE) are to determine the columnar electron content of Comet Halley/s ionosphere and the cometary mass fluence from atmospheric drag by using the radio signals from Giotto during the Halley encounter. The radio science data (S and X-band Doppler and range measurements) will be collected at NASA/s deep-space 64 m tracking antenna at Tidbinbilla near Canberra, in Australia. In order to separate the effects of the terrestrial ionosphere and the interplanetary plasma, S-band Doppler measurements will also be taken at Tidbinbilla along the line-of-sight of Japan/s cometary probe Sakigake during the Giotto-Halley Encounter. The measurements of cometary electron content and mass fluence will be inverted to derive the spatial distribution of the electron and mass (dust and gas) density within Halley/s coma. The GRE is the only experiment on Giotto capable of measuring the low-energy (10 eV) electron bulk population of Halley/s ionosphere and the total cometary mass flow impacting upon the spacecraft.

  19. Motivation and career outcomes of a precollege life science experience for underrepresented minorities

    NASA Astrophysics Data System (ADS)

    Ortega, Robbie Ray

    Minorities continue to be underrepresented in professional science careers. In order to make Science, Technology, Engineering, and Mathematics (STEM) careers more accessible for underrepresented minorities, informal science programs must be utilized to assist in developing interest in STEM for minority youth. In addition to developing interest in science, informal programs must help develop interpersonal skills and leadership skills of youth, which allow youth to develop discrete social behaviors while creating positive and supportive communities thus making science more practical in their lives. This study was based on the premise that introducing underrepresented youth to the agricultural and life sciences through an integrated precollege experience of leadership development with university faculty, scientist, and staff would help increase youths' interest in science, while also increasing their interest to pursue a STEM-related career. Utilizing a precollege life science experience for underrepresented minorities, known as the Ag Discovery Camp, 33 middle school aged youth were brought to the Purdue University campus to participate in an experience that integrated a leadership development program with an informal science education program in the context of agriculture. The week-long program introduced youth to fields of agriculture in engineering, plant sciences, food sciences, and entomology. The purpose of the study was to describe short-term and intermediate student outcomes in regards to participants' interests in career activities, science self-efficacy, and career intentions. Youth were not interested in agricultural activities immediately following the precollege experience. However, one year after the precollege experience, youth expressed they were more aware of agriculture and would consider agricultural careers if their first career choice did not work out for them. Results also showed that the youth who participated in the precollege experience were

    Students' learning interests and attitudes toward science have both been studied for decades. However, the connection between them with students' life experiences about science and technology has not been addressed much. The purpose of this study is to investigate students' learning interests and life experiences about science and technology, and also their attitudes toward technology. A total of 942 urban ninth graders in Taiwan were invited to participate in this study. A Likert scale questionnaire, which was developed from an international project, ROSE, was adapted to collect students' ideas. The results indicated that boys showed higher learning interests in sustainability issues and scientific topics than girls. However, girls recalled more life experiences about science and technology in life than boys. The data also presented high values of Pearson correlation about learning interests and life experiences related to science and technology, and in the perspective on attitudes towards technology. Ways to promote girls' learning interests about science and technology and the implications of teaching and research are discussed as well.

  3. The perspectives of Caribbean high school students' experiences in American science classrooms

    NASA Astrophysics Data System (ADS)

    Ferguson, Renae Luenell

    The purpose of this study was to describe the perspectives of Caribbean high school students' experiences in American science classrooms. Research suggests that psychological, cultural, and socioeconomic perspectives influence the science experiences of African Americans or Blacks; the result of which is under-representation (Lewis et al., 2000). Nonetheless, what is uncertain is if these and other perspectives are similar to the science experiences of Caribbeans who also are majority black by race and rank as the 3 rd largest immigrant population in America's schools (Suarez-Orozco, 2000). Questions guiding this study were: (1) What are the perspectives of Caribbean high school students' experiences in American science classrooms? (2) What can we learn from the perspectives of Caribbean high school students' science experiences that may address issues of participation and interest; consequently, influencing the overall performance of ethnic minorities in school science? Sociocultural theory provides the framework for the analysis of the study. Four Caribbean born students in an American high school participated in this naturalistic qualitative research. A constant comparative method was used to categorize and analyze the data and uncover meaningful patterns that emerged from the four interviews and written documents. Although there were similarities between African Americans' science experiences as documented in the literature and that of Caribbeans in this study, the Caribbean participants relied on prior native experiences to dictate their perspectives of their science experiences in America. According to Caribbean students, American science high schools classrooms utilize an objective style of assessments; are characterized by a lack of teacher support; allow behavioral problems in the classroom; and function through different communication styles than the native Caribbean science classroom environment. This study implies science educators should be sensitive

    In 2007 a social scientist and a designer created a spatial installation to communicate social science research about the regulation of emerging science and technology. The rationale behind the experiment was to improve scientific knowledge production by making the researcher sensitive to new forms of reactions and objections. Based on an account of the conceptual background to the installation and the way it was designed, the paper discusses the nature of the engagement enacted through the experiment. It is argued that experimentation is a crucial way of making social science about science communication and engagement more robust.

  8. Science Teaching Efficacy Beliefs and the Lived Experience of Preservice Elementary Teachers

    NASA Astrophysics Data System (ADS)

    Kettler, Karen A.

    The current study utilized a mixed methods approach to examine the science teaching efficacy beliefs (STEB) of preservice elementary teachers as they participated in a Science Methods course. The following questions were addressed using quantitative survey data and qualitative interviews: What are the STEB of preservice elementary teachers as they progress through a Science Methods course?; How do the STEB of preservice elementary teachers with higher and lower personal science teaching efficacy (PSTE) beliefs change as they progress through a Science Methods course?; What is the nature of the lived experiences of preservice elementary teachers with higher and lower PSTE beliefs as they progress through a Science Methods course?; and How does the meaning developed during the lived experience of preservice elementary teachers with higher and lower PSTE beliefs influence their STEB? The participants (n = 21) included preservice elementary teachers registered for a Science Methods course as part of the "Block" semester, during their final year of teacher preparation prior to the student teaching experience. Quantitative data was obtained via Science Teaching Efficacy Belief Instrument- form B (STEBI-B) surveys taken at the beginning and end of the Science Methods course. This data was utilized to categorize participants into low, medium, and high efficacy groups, depending on how they scored in relation to one another. Qualitative data was obtained concurrently, through in-depth interviews with four "lower" efficacy participants and four "higher" efficacy participants, and was conducted after the "pre" survey and before the "post" survey, utilizing transcendental phenomenological methodology. Results showed a significant difference between pre- and post- survey data, indicating that the participants, as a whole, experienced an increase in PSTE during the Science Methods course (p<0.001). An examination of the specific subgroups (low, medium, and high efficacy) show a

  9. The connection between students' out-of-school experiences and science learning

    NASA Astrophysics Data System (ADS)

    Tran, Natalie A.

    This study sought to understand the connection between students' out-of-school experiences and their learning in science. This study addresses the following questions: (a) What effects does contextualized information have on student achievement and engagement in science? (b) To what extent do students use their out-of-school activities to construct their knowledge and understanding about science? (c) To what extent do science teachers use students' skills and knowledge acquired in out-of-school settings to inform their instructional practices? This study integrates mixed methods using both quantitative and qualitative approaches to answer the research questions. It involves the use of survey questionnaire and science assessment and features two-level hierarchical analyses of student achievement outcomes nested within classrooms. Hierarchical Linear Model (HLM) analyses were used to account for the cluster effect of students nested within classrooms. Interviews with students and teachers were also conducted to provide information about how learning opportunities that take place in out-of-school settings can be used to facilitate student learning in science classrooms. The results of the study include the following: (a) Controlling for student and classroom factors, students' ability to transfer science learning across contexts is associated with positive learning outcomes such as achievement, interest, career in science, self-efficacy, perseverance, and effort. Second, teacher practice using students' out-of-school experiences is associated with decrease in student achievement in science. However, as teachers make more connection to students' out-of-school experiences, the relationship between student effort and perseverance in science learning and transfer gets weaker, thus closing the gaps on these outcomes between students who have more ability to establish the transfer of learning across contexts and those who have less ability to do so. Third, science teachers

  10. Earth at Rest. Aesthetic Experience and Students' Grounding in Science Education

    NASA Astrophysics Data System (ADS)

    Østergaard, Edvin

    2017-07-01

    Focus of this article is the current situation characterized by students' de-rootedness and possible measures to improve the situation within the frame of education for sustainable development. My main line of argument is that science teachers can practice teaching in such a way that students are brought in deeper contact to the environment. I discuss efforts to promote aesthetic experience in science class and in science teacher education. Within a wide range of definitions, my main understanding of aesthetic experience is that of pre-conceptual experience, relational to the environment and incorporated in students' embodied knowledge. I ground the idea of Earth at rest in Husserl's phenomenological philosophy and Heidegger's notion of science' deprivation of the world. A critique of the ontological reversal leads to an ontological re-reversal that implies giving lifeworld experience back its value and rooting scientific concepts in students' everyday lives. Six aspects of facilitating grounding in sustainability-oriented science teaching and teacher education are highlighted and discussed: students' everyday knowledge and experience, aesthetic experience and grounding, fostering aesthetic sensibility, cross-curricular integration with art, ontological and epistemological aspects, and belongingness and (re-)connection to Earth. I conclude that both science students and student-teachers need to practice their sense of caring and belonging, as well as refining their sensibility towards the world. With an intension of educating for a sustainable development, there is an urgent need for a critical discussion in science education when it comes to engaging learners for a sustainable future.

    2007-04-12

    At Vandenberg Air Force Base in California, technicians prepare the AIM spacecraft for fairing installation. The fairing is a molded structure that fits around the spacecraft and forms an aerodynamically smooth nose cone, protecting the spacecraft during launch. Launch will be from a Pegasus XL rocket, carried and released by Orbital Sciences L-1011 jet aircraft. AIM, which stands for Aeronomy of Ice in the Mesosphere, is being prepared for integrated testing and a flight simulation. The AIM spacecraft will fly three instruments designed to study polar mesospheric clouds located at the edge of space, 50 miles above the Earth's surface in the coldest part of the planet's atmosphere. The mission's primary goal is to explain why these clouds form and what has caused them to become brighter and more numerous and appear at lower latitudes in recent years. AIM's results will provide the basis for the study of long-term variability in the mesospheric climate and its relationship to global climate change. Launch is scheduled for April 25.

    Cherney, Michael; Cherney, I.

    2006-12-01

    The decision to study physics or astronomy is affected by many factors, including preferences, motivations, and expectations for success. Differing cognitive profiles contribute to the learning of science through a complex process in which intrinsic capacities are tuned both by everyday experience and by instruction. In an attempt to identify the developmental pathways and intrinsic factors that most strongly influence the choice to study science, we administered an extensive survey to a sample of 400 students. The survey questions were based on Eccles et al.’s model of achievement-related choices and findings showing that previous play experiences, spatial experiences, task beliefs, as well as perceived mathematics ability, motivational and personality characteristics affect mathematics achievement and science career choices. The perceptions of students planning a science career are compared with those planning a career in other areas. Gender differences are also discussed.

  15. Lab experiments are a major source of knowledge in the social sciences.

    PubMed

    Falk, Armin; Heckman, James J

    2009-10-23

    Laboratory experiments are a widely used methodology for advancing causal knowledge in the physical and life sciences. With the exception of psychology, the adoption of laboratory experiments has been much slower in the social sciences, although during the past two decades the use of lab experiments has accelerated. Nonetheless, there remains considerable resistance among social scientists who argue that lab experiments lack "realism" and generalizability. In this article, we discuss the advantages and limitations of laboratory social science experiments by comparing them to research based on nonexperimental data and to field experiments. We argue that many recent objections against lab experiments are misguided and that even more lab experiments should be conducted.

  17. Public Outreach Guerilla Style: Just Add Science to Existing Events

    NASA Astrophysics Data System (ADS)

    Gelderman, Richard

    2016-01-01

    We report on a campaign to use the visual appeal of astronomy as a gateway drug to inject public outreach into settings where people aren't expecting an encounter with science. Our inspiration came from the team at guerillascience.org, who have earned a reputation for creating, at sites around the world, "experiences and events that are unexpected, thought-provoking, but, above all, that delight and entertain." Our goal is to insert astronomy into existing festivals of music, culture, and art; county and state fairs; sporting events; and local farmer's markets. With volunteers and near-zero budgets, we have been able to meaningfully engage with audience members who would never willingly attend an event advertised as science related. By purposefully relating astronomy to the non-science aspects of the event that caused the audience members to attend, new learning experiences are created that alter the often negative pre-conceived notions about science that many of them held before our encounter.

  18. FairMQ for Online Reconstruction - An example on \\overline{{\\rm{P}}}ANDA test beam data

    NASA Astrophysics Data System (ADS)

    Stockmanns, Tobias; PANDA Collaboration

    2017-10-01

    One of the large challenges of future particle physics experiments is the trend to run without a first level hardware trigger. The typical data rates exceed easily hundreds of GBytes/s, which is way too much to be stored permanently for an offline analysis. Therefore a strong data reduction has to be done by selection of only those data, which are physically interesting. This implies that all detector data are read out and have to be processed with the same rate as it is produced. Several different hardware approaches from FPGAs, GPUs to multicore CPUs and mixtures of these systems are under study. Common to all of them is the need to process the data in massive parallel systems. One very convenient way to realize parallel systems on heterogeneous systems is the usage of message queue based multiprocessing. One package that allow development of such application is the FairMQ module in the FairRoot simulation framework developed at GSI. FairRoot is used by several different experiments at and outside the GSI including the \\overline{{{P}}}ANDA experiment. FairMQ is an abstract layer for message queue base application, it has up to now two implementations: ZeroMQ and nanomsg. For the \\overline{{{P}}}ANDA experiment, FairMQ is under test in two different ways. On the one hand side for online processing test beam data of prototypes of sub-detectors of \\overline{{{P}}}ANDA and, in a more generalized way, on time-based simulated data of the complete detector system. The first test on test beam data is presented in this paper.

  19. Do information, price, or morals influence ethical consumption? A natural field experiment and customer survey on the purchase of Fair Trade coffee.

    PubMed

    Andorfer, Veronika A; Liebe, Ulf

    2015-07-01

    We address ethical consumption using a natural field experiment on the actual purchase of Fair Trade (FT) coffee in three supermarkets in Germany. Based on a quasi-experimental before-and-after design the effects of three different treatments - information, 20% price reduction, and a moral appeal - are analyzed. Sales data cover actual ethical purchase behavior and avoid problems of social desirability. But they offer only limited insights into the motivations of individual consumers. We therefore complemented the field experiment with a customer survey that allows us to contrast observed (ethical) buying behavior with self-reported FT consumption. Results from the experiment suggest that only the price reduction had the expected positive and statistically significant effect on FT consumption. Copyright © 2015 Elsevier Inc.

  20. The community comes to campus: the Patient and Community Fair.

    PubMed

    Towle, Angela; Godolphin, William; Kline, Cathy

    2015-08-01

    Community-based learning connects students with local communities so that they learn about the broad context in which health and social care is provided; however, students usually interact with only one or a few organisations that serve a particular population. One example of a community-based learning activity is the health fair in which students provide health promotion and screening for local communities. We adapted the health fair concept to develop a multi-professional educational event at which, instead of providing service, students learn from and about the expertise and resources of not-for-profit organisations. The fair is an annual 1-day event that students can attend between, or in place of, classes. Each community organisation has a booth to display information. One-hour 'patient panels' are held on a variety of topics throughout the day. Evaluation methods include questionnaires, exit interviews and visitor tracking sheets. Over 5 years (2009-2013), the fair increased in size with respect to estimated attendance, number of participating organisations, number of patient panels and number of students for whom the fair is a required curriculum component. Students learn about a range of patient experiences and community resources, and information about specific diseases or conditions. The fair is an efficient way for students to learn about a range of community organisations. It fosters university-community engagement through continuing connections between students, faculty members and community organisations. Lessons learned include the need for community organisations to have techniques to engage students, and ways to overcome challenges of evaluating an informal 'drop-in' event. The fair is an efficient way for students to learn about a range of community organisations. © 2015 John Wiley & Sons Ltd.

    2017-12-01

    Integrity and transparency within research is solidified by a complete set of research products that are findable, accessible, interoperable, and reusable. In other words, they follow the FAIR Guidelines developed by FORCE11.org. Your datasets, images, video, software, scripts, models, physical samples, and other tools and technology are an integral part of the narrative you tell about your research. These research products increasingly are being captured through workflow tools and preserved and connected through persistent identifiers across multiple repositories that keep them safe. They help secure, with your publications, the supporting evidence and integrity of the scientific record. This is the direction that Earth and space science as well as other disciplines is moving. Within our community, some science domains are further along, and others are taking more measured steps. AGU as a publisher is working to support the full scientific record with peer reviewed publications. Working with our community and all the Earth and space science journals, AGU is developing new policies to encourage researchers to plan for proper data preservation and provide data citations along with their research submission and to encourage adoption of best practices throughout the research workflow and data life cycle. Providing incentives, community standards, and easy-to-use tools are some important factors for helping researchers embrace the FAIR Guidelines and support transparency and integrity.

    Quantum entanglement has emerged as a new resource to enhance cooperation and remove dilemmas. This paper aims to explore conditions under which full cooperation is achievable even when the information of payoff is incomplete. Based on the quantum version of the extended classical cash in a hat game, we demonstrate that quantum entanglement may be used for achieving full cooperation or avoiding moral hazards with the reasonable profit distribution policies even when the profit is uncertain to a certain degree. This research further suggests that the fairness of profit distribution should play an important role in promoting full cooperation. It is hopeful that quantum entanglement and fairness will promote full cooperation among distant people from various interest groups when quantum networks and quantum entanglement are accessible to the public.

    The use of technology into science learning encounters problems. One of the problem is teachers’ less technological pedagogical and content knowledge (TPACK) on the implementation of technology itself. The purpose of this study was to investigate science teachers’ experience in using digital technology into science classroom. Through this study science teachers’ technological knowledge (TK) and technological content knowledge (TCK) can be unpacked. Descriptive method was used to depict science teachers’ TK and TCK through questionnaire that consisted of 20 questions. Subjects of this study were 25 science teachers in Bandung, Indonesia. The study was conducted in the context of teacher professional training. Result shows that science teachers still have less TK, yet they have high TCK. The teachers consider characteristics of concepts as main aspect for implementing technology into science teaching. This finding describes teachers’ high technological content knowledge. Meanwhile, science teachers’ technological knowledge was found to be still low since only few of them who can exemplify digital technology that can be implemented into several science concept. Therefore, training about technology implementation into science teaching and learning is necessary as a means to improve teachers’ technological knowledge.

  9. Providing Middle School Students With Science Research Experiences Through Community Partnerships

    NASA Astrophysics Data System (ADS)

    Rodriguez, D.

    2007-12-01

    Science research courses have been around for years at the university and high school level. As inquiry based learning has become more and more a part of the science teacher's vocabulary, many of these courses have adopted an inquiry model for studying science. Learners of all ages benefit from learning through the natural process of inquiry. I participated in the CIRES Earthworks program for science teachers (Colorado University) in the summer of 2007 and experienced, first hand, the value of inquiry learning. With the support and vision of my school administration, and with the support and commitment of community partners, I have developed a Middle School Science Research Program that is transforming how science is taught to students in my community. Swift Creek Middle School is located in Tallahassee, Florida. There are approximately 1000 students in this suburban public school. Students at Swift Creek are required to take one science class each year through 8th grade. As more emphasis is placed on learning a large number of scientific facts and information, in order to prepare students for yearly, standardized tests, there is a concern that less emphasis may be placed on the process and nature of science. The program I developed draws from the inquiry model followed at the CIRES Earthworks program, utilizes valuable community partnerships, and plays an important role in meeting that need. There are three major components to this Middle School Research Program, and the Center for Integrated Research and Learning (CIRL) at the National High Magnetic Field Lab (NHMFL) at Florida State University is playing an important role in all three. First, each student will develop their own research question and design experiments to answer the question. Scientists from the NHMFL are serving as mentors, or "buddy scientists," to my students as they work through the process of inquiry. Scientists from the CIRES - Earthworks program, Florida State University, and other

    2016-10-01

    Scientists know that the power of science lies in thinking like a scientist, rather than in a list of facts and figures, but few science teachers have any personal experience "doing science". They merely encounter science at the level of rote memorization, then teach it to their students in the same way. To break this vicious cycle, two teachers from local public high schools spent 5 weeks conducting research at Boston University on the ionosphere of Venus. They experienced the joys and frustrations of research, which will enable them to better explain to their students the true nature of the process of science. This presentation will summarize how the research program was created and implemented, what worked well and what did not, and how the teachers have made use of their summer research experiences back in the classroom.

    2007-01-01

    NASA has impaneled several internal working groups to provide recommendations to NASA management on ways to evolve and improve Earth Science Data Systems. One of these working groups is the Standards Process Group (SPC). The SPG is drawn from NASA-funded Earth Science Data Systems stakeholders, and it directs a process of community review and evaluation of proposed NASA standards. The working group's goal is to promote interoperability and interuse of NASA Earth Science data through broader use of standards that have proven implementation and operational benefit to NASA Earth science by facilitating the NASA management endorsement of proposed standards. The SPC now has two years of experience with this approach to identification of standards. We will discuss real examples of the different types of candidate standards that have been proposed to NASA's Standards Process Group such as OPeNDAP's Data Access Protocol, the Hierarchical Data Format, and Open Geospatial Consortium's Web Map Server. Each of the three types of proposals requires a different sort of criteria for understanding the broad concepts of "proven implementation" and "operational benefit" in the context of NASA Earth Science data systems. We will discuss how our Standards Process has evolved with our experiences with the three candidate standards.

    2016-12-01

    For more that 20 years, the Global Learning and Observations to Benefit the Environment (GLOBE) Program has sought to increase environment literacy in students by involving them in the process of data collection and scientific research. In 2016, the program expanded to accept observations from citizen scientists of all ages through a relatively simple app. Called GLOBE Observer, the new program aims to help participants feel connected to a global community focused on advancing the scientific understanding of Earth system science while building climate literacy among participants and increasing valuable environmental data points to expand both student and scientific research. In October 2016, GLOBE Observer partnered with the Association of Science & Technology Centers (ASTC) in an international science experiment in which museums and patrons around the world collected cloud observations through GLOBE Observer to create a global cloud map in support of NASA satellite science. The experiment was an element of the International Science Center and Science Museum Day, an event planned in partnership with UNESCO and ASTC. Museums and science centers provided the climate context for the observations, while GLOBE Observer offered a uniform experience and a digital platform to build a connected global community. This talk will introduce GLOBE Observer and will present the results of the experiment, including evaluation feedback on gains in climate literacy through the event.

    Classical economic models assume that people are fully rational and selfish, while experiments often point to different conclusions. A canonical example is the Ultimatum Game: one player proposes a division of a sum of money between herself and a second player, who either accepts or rejects. Based on rational self-interest, responders should accept any nonzero offer and proposers should offer the smallest possible amount. Traditional, deterministic models of evolutionary game theory agree: in the one-shot anonymous Ultimatum Game, natural selection favors low offers and demands. Experiments instead show a preference for fairness: often responders reject low offers and proposers make higher offers than needed to avoid rejection. Here we show that using stochastic evolutionary game theory, where agents make mistakes when judging the payoffs and strategies of others, natural selection favors fairness. Across a range of parameters, the average strategy matches the observed behavior: proposers offer between 30% and 50%, and responders demand between 25% and 40%. Rejecting low offers increases relative payoff in pairwise competition between two strategies and is favored when selection is sufficiently weak. Offering more than you demand increases payoff when many strategies are present simultaneously and is favored when mutation is sufficiently high. We also perform a behavioral experiment and find empirical support for these theoretical findings: uncertainty about the success of others is associated with higher demands and offers; and inconsistency in the behavior of others is associated with higher offers but not predictive of demands. In an uncertain world, fairness finishes first. PMID:23341593

    The purpose of this investigation was to examine the effects of a year long intensive extracurricular middle school science experience on the self-esteem, career goal orientation, and attitude toward science of eighth grade female students using both quantitative and qualitative methods. Sixteen self-selected eighth grade female students participated in extracurricular science experiences such as camping, rock climbing, specimen collecting and hiking, as well as meeting and interacting with female science role models. Data was collected using pre- and posttest methods using the Children's Attitude Toward Science Survey, the Coopersmith Self-Esteem Inventory, and the Self-Directed Search (SDS) Career Explorer. End of year science course grades were examined for seventh and eighth grades and compared to first semester high school grades. Qualitative data was in the form of: (1) focus group interviews conducted prior to field experiences, at the end of all field experiences, and at the end of the first semester of high school, and (2) journal entries from throughout the project. Qualitative data was examined for changes in student perceptions of science as a discipline, self as scientist, women in science, and social comparison of self in science.

    Traditional fairing systems are designed to fully encapsulate and protect their payload from the harsh ascent environment including acoustic vibrations, aerodynamic forces and heating. The Orion fairing separation system performs this function and more by also sharing approximately half of the vehicle structural load during ascent. This load-share condition through launch and during jettison allows for a substantial increase in mass to orbit. A series of component-level development tests were completed to evaluate and characterize each component within Orion's unique fairing separation system. Two full-scale separation tests were performed to verify system-level functionality and provide verification data. This paper summarizes the fairing spring, Pyramidal Separation Mechanism and forward seal system component-level development tests, system-level separation tests, and lessons learned.

  6. Meaningful experiences in science education: Engaging the space researcher in a cultural transformation to greater science literacy

    1993-11-01

    The visceral appeal of space science and exploration is a very powerful emotional connection to a very large and diverse collection of people, most of whom have little or no perspective about what it means to do science and engineering. Therein lies the potential of space for a substantially enhanced positive impact on culture through education. This essay suggests that through engaging more of the space research and development community in enabling unique and 'meaningful educational experiences' for educators and students at the pre-collegiate levels, space science and exploration can amplify its positive feedback on society and act as an important medium for cultural transformation to greater science literacy. I discuss the impact of space achievements on people and define what is meant by a 'meaningful educational experience,' all of which points to the need for educators and students to be closer to the practice of real science. I offer descriptions of two nascent science education programs associated with NASA which have the needed characteristics for providing meaningful experiences that can cultivate greater science literacy. Expansion of these efforts and others like it will be needed to have the desired impact on culture, but I suggest that the potential for the needed resources is there in the scientific research communities. A society in which more people appreciate and understand science and science methods would be especially conducive to human progress in space and on Earth.

  8. The perception of fairness in infant care and mothers' postpartum depression.

    PubMed

    DeMaris, Alfred; Mahoney, Annette

    2017-10-01

    This study investigates a potential causal effect of mothers' perceptions of the fairness of infant care on their postpartum depression. Based on the tenets of equity theory, it is hypothesized that, net of controls, mothers who see infant care as fairly apportioned between themselves and their husbands will be less depressed than others. We utilize data from a longitudinal study of a nonrandom sample of 178 heterosexual couples experiencing the birth of their first child together. The primary focus variable is the mothers' perception in the first couple of months postpartum that infant care is fair to them. Statistical analysis involved the careful chronological sequencing of response variable and controls, along with regression modeling using propensity scores. We find that a perception of fairness is associated with about a quarter of a standard deviation lower depressive symptomatology, controlling for key covariates. Depressive symptomatology is additionally elevated for mothers experiencing more pre-partum depression, and for those who more generally felt, before the birth, that they were overbenefiting in the marriage. This paper contributes to both equity theory and research on postpartum depression. In a scenario in which it is not practical or ethical to randomly assign people to fairness-in-infant-care conditions, we are able to utilize longitudinal data and a natural "experiment," along with propensity-score modeling to attempt to assess the causal impact of fairness in infant care on postpartum depression. The finding that fairness in this arena appears to reduce postpartum depression emphasizes the importance of encouraging father participation in this critical stage of parenting. Limitations of the study with respect to causal inference are also discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  9. Impact of problem finding on the quality of authentic open inquiry science research projects

    NASA Astrophysics Data System (ADS)

    Labanca, Frank

    2008-11-01

    Problem finding is a creative process whereby individuals develop original ideas for study. Secondary science students who successfully participate in authentic, novel, open inquiry studies must engage in problem finding to determine viable and suitable topics. This study examined problem finding strategies employed by students who successfully completed and presented the results of their open inquiry research at the 2007 Connecticut Science Fair and the 2007 International Science and Engineering Fair. A multicase qualitative study was framed through the lenses of creativity, inquiry strategies, and situated cognition learning theory. Data were triangulated by methods (interviews, document analysis, surveys) and sources (students, teachers, mentors, fair directors, documents). The data demonstrated that the quality of student projects was directly impacted by the quality of their problem finding. Effective problem finding was a result of students using resources from previous, specialized experiences. They had a positive self-concept and a temperament for both the creative and logical perspectives of science research. Successful problem finding was derived from an idiosyncratic, nonlinear, and flexible use and understanding of inquiry. Finally, problem finding was influenced and assisted by the community of practicing scientists, with whom the students had an exceptional ability to communicate effectively. As a result, there appears to be a juxtaposition of creative and logical/analytical thought for open inquiry that may not be present in other forms of inquiry. Instructional strategies are suggested for teachers of science research students to improve the quality of problem finding for their students and their subsequent research projects.

    Results of the HypHI Phase 0 experiment with the reaction of 6Li+12C at 2 A GeV are summarised. Invariant mass distributions as well as the lifetime measurements for 3ΛH and 4ΛH are discussed. The lifetime values for both the hypernuclei are respectively observed to be 183+42-32 ps and 140+48-33 ps, being significantly shorter than those of the Λ-hyperon. Statistical analyses of existing lifetime data for 3ΛH up to 2014 confirm a significantly short lifetime of 3ΛH, which is not explained by present models. Observed hypernuclear production cross section values for 3ΛH and 4ΛH are also summarised. In addition, observed signals for the final states of d +π- and t +π- are discussed. All the discussions on the results of the HypHI Phase 0 experiment in this article are based on [1-4]. We also present a new proposed experiment with the FRS (FRagment Separator) at GSI (FAIR Phase 0) to improve the precision of the hypernuclear spectroscopy with peripheral heavy ion induced reactions.

  12. Experiment Prevails Over Observation in Geophysical Science

    NASA Astrophysics Data System (ADS)

    Galvin, C.

    2006-05-01

    Thomson and Tait gave their name to a text (T and T') that sums up nineteenth century mechanics. T and T' says that scientists gain knowledge of the natural universe and the laws that regulate it through Experience. T and T' divides Experience into Observation and Experiment. The posthumous (1912) edition of T and T' appeared seven years before Eddington's expeditions to observe the eclipse of 29 May 1919 that demonstrated the bending of starlight predicted by Einstein's general theory of relativity. During the 2005 centenary of young Einstein's remarkably productive year, Eddington's (1919) result was frequently remembered, but the description in 2005 of what Eddington did in 1919 often differed from what Eddington said that he did. In his words then, Eddington observed; in words from scientists, historians of science, and philosophers of science during 2005, Eddington often experimented. In 1912, T and T' had distinguished Observation from Experiment with an apt contrast: ""When, as in astronomy, we endeavour to ascertain these causes by simply watching, we observe; when, as in our laboratories, we interfere arbitrarily with the causes or circumstances of a phenomenon, we are said to experiment"". (italics in T and T'). Eddington himself conformed to this distinction in his report (Physical Society of London, 1920). In its Preface, he states that observations were made at each of two stations, and concludes that ""I think it may now be stated that Einstein's law of gravitation is definitely established by observation..."". Chapter V of that report deals with The Crucial Phenomena. In this chapter, some form of the word observe (noun, verb, adjective, adverb) appears 13 times. In this chapter, experiment appears only as experimental, and then only twice. Einstein's prediction, with Eddington's observations, profoundly impressed contemporary philosophers of science. Karl Popper, then aged 17, considered Eddington's findings to effect a turning point in his career

    The Physical Science Informatics (PSI) system is the next step in this an effort to make NASA sponsored flight data available to the scientific and engineering community, along with the general public. The experimental data, from six overall disciplines, Combustion Science, Fluid Physics, Complex Fluids, Fundamental Physics, and Materials Science, will present some unique challenges. Besides data in textual or numerical format, large portions of both the raw and analyzed data for many of these experiments are digital images and video, requiring large data storage requirements. In addition, the accessible data will include experiment design and engineering data (including applicable drawings), any analytical or numerical models, publications, reports, and patents, and any commercial products developed as a result of the research. This objective of paper includes the following: Present the preliminary layout (Figure 2) of MABE data within the PSI database. Obtain feedback on the layout.

  2. Research Experiences for Science Teachers: The Impact On Their Students

    NASA Astrophysics Data System (ADS)

    Dubner, J.

    2005-12-01

    Deficiencies in science preparedness of United States high school students were recognized more than two decades ago, as were some of their underlying causes. Among the primary causes are the remoteness of the language, tools, and concepts of science from the daily experiences of teachers and students, and the long-standing national shortage of appropriately prepared science teachers. Secondary school science teachers are challenged each school year by constantly changing content, new technologies, and increasing demands for standards-based instruction. A major deficiency in the education of science teachers was their lack of experience with the practice of science, and with practicing scientists. Providing teachers with opportunities to gain hands-on experience with the tools and materials of science under the guidance and mentorship of leading scientists in an environment attuned to professional development, would have many beneficial effects. They would improve teachers' understanding of science and their ability to develop and lead inquiry- and standards-based science classes and laboratories. They would enable them to communicate the vitality and dynamism of science to their students and to other teachers. They would enhance their ability to motivate and guide students. From its inception, Columbia University's Summer Research Program for Science Teacher's goal has been to enhance interest and improve performance in science of students in New York City area schools. The program seeks to achieve this goal by increasing the professional competence of teachers. Our ongoing program evaluation shows that following completion of the program, the teachers implement more inquiry-based classroom and laboratory exercises, increase utilization of Internet resources, motivate students to participate in after school science clubs and Intel-type science projects; and create opportunities for students to investigate an area of science in greater depth and for longer periods

    1989-01-01

    A workshop was convened to develop hypothetical experiments to be used as a baseline for space station designer and equipment specifiers to ensure responsiveness to the users, the life science community. Sixty-five intra- and extramural scientists were asked to describe scientific rationales, science objectives, and give brief representative experiment descriptions compatible with expected space station accommodations, capabilities, and performance envelopes. Experiment descriptions include hypothesis, subject types, approach, equipment requirements, and space station support requirements. The 171 experiments are divided into 14 disciplines.

    The development of the Shuttle Transportation System (STS) by the United States and the Spacelab pressurized modules and pallets by the European Space Agency (ESA) presents a unique multi-mission space experimentation capability to scientists and researchers of all disciplines. This capability is especially pertinent to life scientists involved in all areas of biological and behavioral research. This paper explains the solicitation, evaluation, and selection process involved in establishing life sciences experiment payloads. Explanations relative to experiment hardware development, experiment support hardware (CORE) concepts, hardware integration and test, and concepts of direct Principal Investigator involvement in the missions are presented as they are being accomplished for the first Spacelab mission. Additionally, discussions of future plans for life sciences dedicated Spacelab missions are included in an attempt to define projected capabilities for space research in the 1980s utilizing the STS.

    This paper discusses the establishment of a clinical trial of an Ebola vaccine candidate in Kambia District, Northern Sierra Leone during the epidemic, and analyses the role of social science research in ensuring that lessons from the socio-political context, the recent experience of the Ebola outbreak, and learning from previous clinical trials were incorporated in the development of community engagement strategies. The paper aims to provide a case study of an integrated social science and communications system in the start-up phase of the clinical trial. The paper is based on qualitative research methods including ethnographic observation, interviews with trial participants and key stakeholder interviews. Through the case study of EBOVAC Salone, the paper suggests ways in which research can be used to inform communication strategies before and during the setting up of the trial. It explores notions of power, fairness and trust emerging from analysis of the Sierra Leonean context and through ethnographic research, to reflect on three situations in which social scientists and community liaison officers worked together to ensure successful community engagement. Firstly, a section on "power" considers the pitfalls of considering communities as homogeneous and shows the importance of understanding intra-community power dynamics when engaging communities. Secondly, a section on "fairness" shows how local understandings of what is fair can help inform the design of volunteer recruitment strategies. Finally, a section on "trust" highlights how historically rooted rumours can be effectively addressed through active dialogue rather than through an approach focused on correcting misinformation. The paper firstly emphasises the value of social science in the setting up of clinical trials, in terms of providing an in depth understanding of context and social dynamics. Secondly, the paper suggests the importance of a close collaboration between research and community

    Upadhyay, Bhaskar; Maruyama, Geoffrey; Albrecht, Nancy

    2017-12-01

    In this interpretive case study, we draw from sociocultural theory of learning and culturally relevant pedagogy to understand how urban students from nondominant groups leverage their sociocultural experiences. These experiences allow them to gain an empowering voice in influencing science content and activities and to work towards self-determining the sciences that are personally meaningful. Furthermore, tying sociocultural experiences with science learning helps generate sociopolitical awareness among students. We collected interview and observation data in an urban elementary classroom over one academic year to understand the value of urban students' sociocultural experiences in learning science and choosing science activities.

  15. Pura Vida: Teacher Experiences in a Science Education Study Abroad Course in Costa Rica

    NASA Astrophysics Data System (ADS)

    Medina, Stephanie Rae

    The purpose of this study was to explore the experiences of classroom teachers who participated in a science-focused study abroad during their time as a preservice teacher and to explore how they are using their study abroad experiences in science curriculum planning and in classroom instruction. This study is guided by two research questions: 1) what are the study abroad experiences that have influenced classroom teachers; and, 2) how do classroom teachers incorporate study abroad experiences into science curriculum planning and instruction in the classroom? Participants were two in-service science teachers from schools located in the Southwestern United States. The participants were enrolled in the course, Environmental Science and Multicultural Experience for K-8 Teachers offered through the Department of Educational Leadership, Curriculum and Instruction during their time as preservice teachers. The course included a two-week study abroad component in Costa Rica. Participants spent their mornings observing a monolingual, Spanish-speaking elementary classroom followed by a faculty-led multicultural seminar. Afternoons during the study abroad experience were dedicated to field science activities such as quantifying plant and animal biodiversity, constructing elevation profiles, determining nutrient storage in soil, and calculating river velocity. Throughout the course students participated in science-focused excursions. A cross case study design was used to answer the two research questions guiding this dissertation study. Data collection included participant-created concept maps of the science experiences during the study abroad experience, in-depth interviews detailing the study abroad experience and classroom instruction, and participant reflective journal entries. Cross-caseanalysis was employed to explore the uniqueness of each participant's experience and commonalities between the cases. Trustworthiness was established by utilizing multiple sources of data

  16. Fairness requires deliberation: the primacy of economic over social considerations.

    Hochman, Guy; Ayal, Shahar; Ariely, Dan

    2015-01-01

    While both economic and social considerations of fairness and equity play an important role in financial decision-making, it is not clear which of these two motives is more primal and immediate and which one is secondary and slow. Here we used variants of the ultimatum game to examine this question. Experiment 1 shows that acceptance rate of unfair offers increases when participants are asked to base their choice on their gut-feelings, as compared to when they thoroughly consider the available information. In line with these results, Experiments 2 and 3 provide process evidence that individuals prefer to first examine economic information about their own utility rather than social information about equity and fairness, even at the price of foregoing such social information. Our results suggest that people are more economically rational at the core, but social considerations (e.g., inequality aversion) require deliberation, which under certain conditions override their self-interested impulses.

    Zhang, Chuan; Schempp, Alwin

    2009-10-01

    A 325 MHz, 35 mA, 3 MeV Radio-Frequency Quadrupole (RFQ) accelerator will be operated as the first accelerating structure of the proton linac injector for the newly planned international science center Facility for Antiproton and Ion Research (FAIR) at GSI, Germany. In previous design studies, two high beam intensities, 70 and 100 mA, were used. Most recently, the design intensity has been changed to 45 mA, which is closer to the operational value. Taking advantage of the so-called New Four-Section Procedure, a new design, which is upgradable from 45 to 100 mA, has been developed for the FAIR proton RFQ. Besides the upgradability analyses, robustness studies of the new design to spatial displacements of the input beam and field errors are presented as well.

  19. Disorientating, fun or meaningful? Disadvantaged families' experiences of a science museum visit

    Archer, Louise; Dawson, Emily; Seakins, Amy; Wong, Billy

    2016-12-01

    It is widely agreed that there is a need to increase and widen science participation. Informal science learning environments (ISLEs), such as science museums, may provide valuable spaces within which to engage visitors—yet the visitor profile of science museums remains narrow. This paper seeks to understand the experiences of socially disadvantaged families within such spaces. Using a Bourdieusian analytic lens, we analyse qualitative data from a small study conducted with ten parents and ten children from an urban school who visited a large science museum. Data includes pre- and post-interviews, audio recordings and visit fieldnotes. We characterised families' experiences as falling into three discourses, as `disorientating', `fun' or `meaningful' visits. Analysis identifies how the families' experiences, and the likelihood of deriving science learning from the visit, were shaped through interactions of habitus and capital. Implications for improving equity and inclusion within ISLEs are discussed.

  2. Expensing stock options: a fair-value approach.

    PubMed

    Kaplan, Robert S; Palepu, Krishna G

    2003-12-01

    Now that companies such as General Electric and Citigroup have accepted the premise that employee stock options are an expense, the debate is shifting from whether to report options on income statements to how to report them. The authors present a new accounting mechanism that maintains the rationale underlying stock option expensing while addressing critics' concerns about measurement error and the lack of reconciliation to actual experience. A procedure they call fair-value expensing adjusts and eventually reconciles cost estimates made at grant date with subsequent changes in the value of the options, and it does so in a way that eliminates forecasting and measurement errors over time. The method captures the chief characteristic of stock option compensation--that employees receive part of their compensation in the form of a contingent claim on the value they are helping to produce. The mechanism involves creating entries on both the asset and equity sides of the balance sheet. On the asset side, companies create a prepaid-compensation account equal to the estimated cost of the options granted; on the owners'-equity side, they create a paid-in capital stock-option account for the same amount. The prepaid-compensation account is then expensed through the income statement, and the stock option account is adjusted on the balance sheet to reflect changes in the estimated fair value of the granted options. The amortization of prepaid compensation is added to the change in the option grant's value to provide the total reported expense of the options grant for the year. At the end of the vesting period, the company uses the fair value of the vested option to make a final adjustment on the income statement to reconcile any difference between that fair value and the total of the amounts already reported.

  3. An Investigation of the Effects of Authentic Science Experiences Among Urban High School Students

    NASA Astrophysics Data System (ADS)

    Chapman, Angela

    Providing equitable learning opportunities for all students has been a persistent issue for some time. This is evident by the science achievement gap that still exists between male and female students as well as between White and many non-White student populations (NCES, 2007, 2009, 2009b) and an underrepresentation of female, African-American, Hispanic, and Native Americans in many science, technology, engineering, and mathematics (STEM) related careers (NCES, 2009b). In addition to gender and ethnicity, socioeconomic status and linguistic differences are also factors that can marginalize students in the science classroom. One factor attributed to the achievement gap and low participation in STEM career is equitable access to resources including textbooks, laboratory equipment, qualified science teachers, and type of instruction. Extensive literature supports authentic science as one way of improving science learning. However, the majority of students do not have access to this type of resource. Additionally, extensive literature posits that culturally relevant pedagogy is one way of improving education. This study examines students' participation in an authentic science experience and argues that this is one way of providing culturally relevant pedagogy in science classrooms. The purpose of this study was to better understand how marginalized students were affected by their participation in an authentic science experience, within the context of an algae biofuel project. Accordingly, an interpretivist approach was taken. Data were collected from pre/post surveys and tests, semi-structured interviews, student journals, and classroom observations. Data analysis used a mixed methods approach. The data from this study were analyzed to better understand whether students perceived the experience to be one of authentic science, as well as how students science identities, perceptions about who can do science, attitudes toward science, and learning of science practices

  4. The influence of field experiences on stages of concern and attitudes of preservice teachers toward science and science teaching

    NASA Astrophysics Data System (ADS)

    Strawitz, Barbara M.; Malone, Mark R.

    The purpose of the study was to determine whether the field experience component of an undergraduate science methods course influenced teachers' concerns and attitudes toward science and science teaching. Age, grade-point average, openmindedness, and school assignment were examined as factors which might explain some of the variance in the dependent measures. A one-group pretest-posttest design was used. Students were administered the Teacher Concerns Questionnaire, the Science Teaching Attitude Scales, and the Rokeach Dogmatism Scale approximately eight weeks after the pretest. Results indicated that field experiences did not significantly change student concerns about teaching science but significantly improved student attitudes toward science and science teaching. Students differing in age, grade-point average, and openmindedness did not difer significantly in changes in concerns and changes in attitude toward science and science teaching. Students assigned to different schools differed significantly in changes in attitude toward science.

  5. A case of learning to teach elementary science: Investigating beliefs, experiences, and tensions

    NASA Astrophysics Data System (ADS)

    Bryan, Lynn Ann

    This study examines how preservice elementary teacher beliefs and experiences within the context of reflective science teacher education influence the development of professional knowledge. From a cognitive constructivist theoretical perspective, I conducted a case analysis to investigate the beliefs about science teaching and learning held by a preservice teacher (Barbara), identify the tensions she encountered in learning to teach elementary science, understand the frames from which she identified problems of practice, and discern how her experiences influenced the process of reflecting on her own science teaching. From an analysis of interviews, observation, and written documents, I constructed a profile of Barbara's beliefs that consisted of three foundational and three dualistic beliefs about science teaching and learning. Her foundational beliefs concerned: (a) the value of science and science teaching, (b) the nature of scientific concepts and goals of science instruction, and (c) control in the science classroom. Barbara held dualistic beliefs about: (a) how children learn science, (b) the science students' role, and (c) the science teacher's role. The dualistic beliefs formed two contradictory nests of beliefs. One nest, grounded in life-long science learner experiences, reflected a didactic teaching orientation and predominantly guided her practice. The second nest, not well-grounded in experience, embraced a hands-on approach and predominantly guided her vision of practice. Barbara encountered tensions in thinking about science teaching and learning as a result of inconsistencies between her vision of science teaching and her actual practice. Confronting these tensions prompted Barbara to rethink the connections between her classroom actions and students' learning, create new perspectives for viewing her practice, and consider alternative practices more resonant with her visionary beliefs. However, the self-reinforcing belief system created by her

    The Soil Science Society of America (SSSA), founded in 1936, fosters the transfer of knowledge and practices to sustain soils globally, and now serves 6,000 members worldwide. It is also home to over 1,000 certified professionals dedicated to advancing the field of soil science. The Society provides information about soils in relation to crop production, environmental quality, ecosystem sustainability, bioremediation, waste management, recycling, and wise land use. We provide high-impact research publications, educational programs, certifications, and science-policy initiatives, which will be described in more detail in this presentation. The need for soil science education to a wider audience and development and promotion of soils-based policy initiatives, has increased in the last decade with recognition of the role soils play in sustaining life, population well-being at the nexus of food, energy, and water security. To address these needs, SSSA has two general public outreach sites online: www.soils.org/discover-soils and https://soilsmatter.wordpress.com/, reaching over a half-million viewers per year, as well as social media platforms. We are dedicated to increasing interest and awareness of soil science among K-12 teachers and their students, and working to integrate more information on soil science into the science curriculum of schools over multiple grade levels. For instance, we have a website dedicated to children (http://www.soils4kids.org/), which describes fun games to play with soil, suggestions for science-fair experiments, and opens their minds to careers in soil science. Another site (http://www.soils4teachers.org/) is dedicated to the needs of school teachers, providing ready resources for the classroom. Society members have even authored books ("Soil! Get the Inside Scoop" for one) to get children aged 9 to 12, excited about the living world of soil. In keeping with the times, a blog called "Soils Matter" is hosted by Society staff and now has

  7. Altruism and fairness: Unnatural selection?

    PubMed

    Cela-Conde, Camilo J; Burges, Lucrecia; Nadal, Marcos; Olivera, Antonio

    2010-02-01

    Darwin admitted that the evolution of moral phenomena such as altruism and fairness, which are usually in opposition to the maximization of individual reproductive success, was not easily accounted for by natural selection. Later, authors have proposed additional mechanisms, including kin selection, inclusive fitness, and reciprocal altruism. In the present work, we explore the extent to which sexual selection has played a role in the appearance of human moral traits. It has been suggested that because certain moral virtues, including altruism and kindness, are sexually attractive, their evolution could have been shaped by the process of sexual selection. Our review suggests that although it is possible that sexual selection played such a role, it is difficult to determine the extent of its relevance, the specific form of this influence, and its interplay with other evolutionary mechanisms. 2009 Académie des sciences.

  9. The effect of alternative clinical teaching experience on preservice science teachers' self-efficacy

    NASA Astrophysics Data System (ADS)

    Klett, Mitchell Dean

    The purpose of this study was to compare different methods of alternative clinical experience; family science nights and Saturday science (authentic teaching) against micro-teaching (peer teaching) in terms of self-efficacy in science teaching and teaching self-efficacy. The independent variable, or cause, is teaching experiences (clinical vs. peer teaching); the dependent variable, or effect, is two levels of self-efficacy. This study was conducted at the University of Idaho's main campus in Moscow and extension campus in Coeur d'Alene. Four sections of science methods were exposed to the same science methods curriculum and will have opportunities to teach. However, each of the four sections were exposed to different levels or types of clinical experience. One section of preservice teachers worked with students in a Saturday science program. Another section worked with students during family science nights. The third worked with children at both the Saturday science program and family science nights. The last section did not have a clinical experience with children, instead they taught in their peer groups and acted as a control group. A pre-test was given at the beginning of the semester to measure their content knowledge, teaching self-efficacy and self-efficacy in science teaching. A post-test was given at the end of the semester to see if there was any change in self-efficacy or science teaching self-efficacy. Throughout the semester participants kept journals about their experiences and were interviewed after their alternative clinical teaching experiences. These responses were categorized into three groups; gains in efficacy, no change in efficacy, and drop in efficacy. There was a rise in teaching efficacy for all groups. The mean scores for personal teaching efficacy dropped for the Monday-Wednesday and Tuesday-Thursday group while the both Coeur D'Alene groups remained nearly unchanged. There was no significant change in the overall means for science

    Nomad was deployed for a 45 day traverse in the Atacama Desert, Chile, during the summer of 1997. During this traverse, 1 week was devoted to science experiments. The goal of the science experiments was to test different planetary surface exploration strategies that included (1) a Mars mission simulation, (2) a science on the fly experiment, where the rover was kept moving 75% of the operation time. (The goal of this operation was to determine whether or not successful interpretation of the environment is related to the time spent on a target. The role of mobility in helping the interpretation was also assessed.) (3) a meteorite search using visual and instrumental methods to remotely identify meteorites in extreme environments, and (4) a time-delay experiment with and without using the panospheric camera. The results were as follow: the remote science team positively identified the main characteristics of the test site geological environment. The science on the fly experiment showed that the selection of appropriate targets might be even more critical than the time spent on a study area to reconstruct the history of a site. During the same operation the science team members identified and sampled a rock from a Jurassic outcrop that they proposed to be a fossil. The presence of paleolife indicators in this rock was confirmed later by laboratory analysis. Both visual and instrumental modes demonstrated the feasibility, in at least some conditions, of carrying out a field search for meteorites by using remote-controlled vehicles. Finally, metrics collected from the observation of the science team operations, and the use team members made of mission data, provided critical information on what operation sequences could be automated on board rovers in future planetary surface explorations.

  16. Experience and Reflection: Preservice Science Teachers' Capacity for Teaching Inquiry

    NASA Astrophysics Data System (ADS)

    Melville, Wayne; Fazio, Xavier; Bartley, Anthony; Jones, Doug

    2008-10-01

    In this article, we investigate the relationship between preservice teachers’ inquiry experience and their capacity to reflect on the challenges involved in implementing inquiry into classrooms. For data, we draw on the personal narratives of preservice science teachers enrolled in science instruction courses. Preservice teachers with extensive inquiry experiences perceive implementation challenges principally in terms of teaching and student learning. This contrasts with the perceptions of preservice teachers with limited inquiry experience for whom the main concerns relate to the negative perceptions of others, time, the curriculum, and materials. By identifying these perceptions, it may be possible to develop courses that assist limited and moderate-experience preservice teachers’ move toward the perceptions of their more inquiry experienced colleagues.

  17. Expectation of fairness: a turning point in the professional satisfaction of Iranian nurses.

    The professional satisfaction of staff is one of the most challenging organizational concepts that can enhance the efficiency level of organizations. In a similar vein, the professional satisfaction of nurses is of considerable importance, in that, professional dissatisfaction among nurses could result in emotional detachment, depression, anger, evasion from work, and inefficacy and would negatively impact the organization's work rate. The aim of this study was to understand Iranian nurses' experiences of the concept of professional satisfaction. This was a qualitative study conducted with a targeted sampling of 10 nurses (4 men and 6 women) in 2015. The data were collected through conducting in-depth interviews, and textual data were analyzed subsequently using the Qualitative Content Analysis (QCA) method. The findings of this study pointed to "fair conduct," which was comprised of three sub-categories, i.e., expectation of fairness in social-professional settings, expectation of fairness in receiving professional benefits, and expectation of fairness in the area of professional interactions. There are various ups and downs in nursing due to the challenging nature of the profession, from the initial education at the university until retirement. According to the findings of this study, a lack of fairness in social-professional settings, a lack of fairness in receiving professional benefits, and a lack of fairness in the area of professional interactions were among the factors that have great impacts on the degree of professional dissatisfaction among nurses.

    At Fair Oaks Dairy, dried manure solids (''DMS'') are currently used as a low value compost. United Power was engaged to evaluate the feasibility of processing these DMS into ethanol utilizing commercially available cellulosic biofuels conversion platforms. The Fair Oaks Dairy group is transitioning their traditional ''manure to methane'' mesophilic anaerobic digester platform to an integrated bio-refinery centered upon thermophilic digestion. Presently, the Digested Manure Solids (DMS) are used as a low value soil amendment (compost). United Power evaluated the feasibility of processing DMS into higher value ethanol utilizing commercially available cellulosic biofuels conversion platforms. DMS was analyzed and overmore » 100 potential technology providers were reviewed and evaluated. DMS contains enough carbon to be suitable as a biomass feedstock for conversion into ethanol by gasification technology, or as part of a conversion process that would include combined heat and power. In the first process, 100% of the feedstock is converted into ethanol. In the second process, the feedstock is combusted to provide heat to generate electrical power supporting other processes. Of the 100 technology vendors evaluated, a short list of nine technology providers was developed. From this, two vendors were selected as finalists (one was an enzymatic platform and one was a gasification platform). Their selection was based upon the technical feasibility of their systems, engineering expertise, experience in commercial or pilot scale operations, the ability or willingness to integrate the system into the Fair Oaks Biorefinery, the know-how or experience in producing bio-ethanol, and a clear path to commercial development.« less

  1. Extending the FairRoot framework to allow for simulation and reconstruction of free streaming data

    The FairRoot framework is the standard framework for simulation, reconstruction and data analysis for the FAIR experiments. The framework is designed to optimise the accessibility for beginners and developers, to be flexible and to cope with future developments. FairRoot enhances the synergy between the different physics experiments. As a first step toward simulation of free streaming data, the time based simulation was introduced to the framework. The next step is the event source simulation. This is achieved via a client server system. After digitization the so called "samplers" can be started, where sampler can read the data of the corresponding detector from the simulation files and make it available for the reconstruction clients. The system makes it possible to develop and validate the online reconstruction algorithms. In this work, the design and implementation of the new architecture and the communication layer will be described.

    2013-12-01

    In case studies of two first-year elementary classroom teachers, we explored the influence of informal science education (ISE) they experienced in their teacher education program. Our theoretical lens was identity development, delimited to classroom science teaching. We used complementary data collection methods and analysis, including interviews, electronic communications, and drawing prompts. We found that our two participants referenced as important the ISE experiences in their development of classroom science identities that included resilience, excitement and engagement in science teaching and learning-qualities that are emphasized in ISE contexts. The data support our conclusion that the ISE experiences proved especially memorable to teacher education interns during the implementation of the No Child Left Behind policy which concentrated on school-tested subjects other than science.

    The Compressed Baryonic Matter (CBM) Experiment is one of the core experiments of the future FAIR facility near Darmstadt (Germany). The fixed-target experiment will explore the phase diagram of strongly interacting matter in the regime of high net baryon densities with numerous probes, among them open charm mesons. The Micro Vertex Detector (MVD) will provide the secondary vertex resolution of ∼ 50 μm along the beam axis, contribute to the background rejection in dielectron spectroscopy, and to the reconstruction of weak decays. The detector comprises four stations placed at 5, 10, 15, and 20 cm downstream the target and inside the target vacuum. The stations will be populated with highly granular CMOS Monolithic Active Pixel Sensors, which will feature a spatial resolution of < 5 μm, a non-ionizing radiation tolerance of >1013neq /cm2, an ionizing radiation tolerance of ∼ 3 Mrad, and a readout speed of a few 10 μs/frame. This work introduces the MVD-PRESTO project, which aims at integrating a precursor of the second station of the CBM-MVD meeting the following requirements: material budget of x /X0 < 0.5 %, vacuum compatibility, double-sided sensor integration on a Thermal Pyrolytic Graphite (TPG) carrier, and heat evacuation of about 350 mW/cm2/sensor with a temperature gradient of a few K/cm.

  4. Mapping the entangled ontology of science teachers' lived experience

    NASA Astrophysics Data System (ADS)

    Daugbjerg, Peer S.; de Freitas, Elizabeth; Valero, Paola

    2015-09-01

    In this paper we investigate how the bodily activity of teaching, along with the embodied aspect of lived experience, relates to science teachers' ways of dealing with bodies as living organisms which are both the subject matter as well as the site or vehicle of learning. More precisely, the following questions are pursued: (1) In what ways do primary science teachers refer to the lived and living body in teaching and learning? (2) In what ways do primary science teachers tap into past experiences in which the body figured prominently in order to teach students about living organisms? We draw on the relational ontology and intra-action of Karen Barad (J Women Cult Soc 28(3): 801, 2003) as she argues for a "relational ontology" that sees a relation as a dynamic flowing entanglement of a matter and meaning. We combine this with the materialist phenomenological studies of embodiment by SungWon Hwang and Wolff-Michael Roth (Scientific and mathematical bodies, Sense Publishers, Rotterdam, 2011), as they address how the teachers and students are present in the classroom with/in their "living and lived bodies". Our aim is to use theoretical insights from these two different but complementary approaches to map the embodiment of teachers' experiences and actions. We build our understanding of experience on the work of John Dewey (Experience and education, Simon & Schuster, New York, 1938) and also Jean Clandinin and Michael Connelly (Handbook of qualitative research, Sage Publications, California, 2000), leading us to propose three dimensions: settings, relations and continuity. This means that bodies and settings are mutually entailed in the present relation, and furthermore that the past as well as the present of these bodies and settings—their continuity—is also part of the present relation. We analyse the entanglement of lived experience and embodied teaching using these three proposed dimensions of experience. Analysing interviews and observations of three Danish

    The purpose of this study was to investigate the impact of a summer science camp teaching experience on preservice elementary teachers' science teaching efficacy, science content knowledge, and understanding of the nature of science. Master's degree students enrolled in the elementary Fairfax Partnership Schools (FPS, n = 21) cohort served as the treatment group, while those enrolled in the Loudoun Partnership Schools (LPS, n = 15) and Professional Development Schools (PDS, n = 24) cohorts at George Mason University served as the control groups. The treatment group planned for and taught a two-week inquiry- and problem-based summer science camp as part of their science methods course, while the control groups did not. The Science Teaching Efficacy Belief Instrument (STEBI), a science content assessment, a personal data questionnaire, and a modified version of the Views of Nature of Science Questionnaire (VNOS-C) were administered to the participants at the beginning and end of their science methods course. Analyses revealed significant increases for the FPS group in general science teaching efficacy, personal science teaching efficacy, science teaching outcome expectancy, general science knowledge, biology content knowledge, chemistry content knowledge, and understanding of NOS; the LPS group in general science teaching efficacy, personal science teaching efficacy, chemistry content knowledge, and understanding of NOS; and, the PDS group in general science teaching efficacy, personal science teaching efficacy, and chemistry content knowledge. Additionally, the FPS group had significantly higher general science teaching efficacy than both control groups, personal science teaching efficacy than the PDS group, and understanding of NOS than the LPS group. Overall, the findings indicate that course length is not as important for developing preservice teachers' teaching efficacy and understanding of content as having connected, authentic field-based teaching experiences

    Understanding preservice teachers' memories of their education may aid towards articulating high-impact teaching practices. This study describes 246 preservice teachers' perceptions of their secondary science education experiences through a questionnaire and 28-item survey. ANOVA was statistically significant about participants' memories of science with 15 of the 28 survey items. Descriptive statistics through SPSS further showed that a teacher's enthusiastic nature (87%) and positive attitude towards science (87%) were regarded as highly memorable. In addition, explaining abstract concepts well (79%), and guiding the students' conceptual development with practical science activities (73%) may be considered as memorable secondary science teaching strategies. Implementing science lessons with one or more of these memorable science teaching practices may "make a difference" towards influencing high school students' positive long-term memories about science and their science education. Further research in other key learning areas may provide a clearer picture of high-impact teaching and a way to enhance pedagogical practices.

    A wind tunnel test was conducted to study the aerodynamics of helicopter hub and pylon fairings. The test was conducted in the 7-by 10 Foot Subsonic Wind Tunnel (Number 2) at Ames Research Center using a 1/5-scale XH-59A fuselage model. The primary focus of the test was on the rotor hub fairing and pylon mutual interference drag. Parametric studies of pylon and hub fairing geometry were also conducted. This report presents the major findings of the test as well as tabulated force and moment data, flow visualization photographs, and graphical presentations of the drag data. The test results indicate that substantial drag reduction can be attained through the use of a cambered hub fairing with circular arc upper surface and flat lower surface. Furthermore, a considerable portion of the overall drag reduction is attributed to the reduction in the hub-on-pylon interference drag. It is also observed that the lower surface curvature of the fairing has a strong influence on the hub fairing and on pylon interference drag. However, the drag reduction benefit that was obtained by using the cambered hub fairing with a flat lower surface was adversely affected by the clearance between the hub fairing and the pylon.

    A sense of fairness plays a critical role in supporting human cooperation. Adult norms of fair resource sharing vary widely across societies, suggesting that culture shapes the acquisition of fairness behaviour during childhood. Here we examine how fairness behaviour develops in children from seven diverse societies, testing children from 4 to 15 years of age (n = 866 pairs) in a standardized resource decision task. We measured two key aspects of fairness decisions: disadvantageous inequity aversion (peer receives more than self) and advantageous inequity aversion (self receives more than a peer). We show that disadvantageous inequity aversion emerged across all populations by middle childhood. By contrast, advantageous inequity aversion was more variable, emerging in three populations and only later in development. We discuss these findings in relation to questions about the universality and cultural specificity of human fairness.

  10. Why Everyday Experience? Interpreting Primary Students' Science Discourse from the Perspective of John Dewey

    Na, Jiyeon; Song, Jinwoong

    2014-05-01

    The purposes of this study were, based on John Dewey's ideas on experience, to examine how primary students used their own everyday experience and were affected by own and others' experience in science discourse, and to illuminate the implications of experience in science education. To do these, science discourses by a group of six fourth-graders were observed, where they talked about their ideas related to thermal concepts. The data was collected through interviews and open-ended questions, analyzed based on Dewey's perspective, and depicted as the discourse map which was developed to illustrate students' transaction and changing process of students' ideas. The results of the analysis showed typical examples of Dewey's notions of experience, such as the principles of continuity and of transaction and of different types of experience, examples of `the expanded continuity and transaction', and science discourse as inquiry. It was also found that students' everyday experiences played several roles: as a rebuttal for changing their own ideas or others', backing for assurance of their own ideas in individual students' inner changes after discourse with others, and backing for other's ideas. Based on these observations, this study argues that everyday experience should be considered as a starting point for primary students' science learning because most of their experience comes from everyday, not school science, contexts. In addition, to evoke educative experience in science education, it is important for teachers to pay more attention to Dewey's notions of the principles of continuity and of transaction and to their educational implications.

  11. Sublime science: Teaching for scientific sublime experiences in middle school classrooms

    NASA Astrophysics Data System (ADS)

    Cavanaugh, Shane

    Due to a historical separation of cognition and emotion, the affective aspects of learning are often seen as trivial in comparison to the more 'essential' cognitive qualities - particularly in the domain of science. As a result of this disconnect, feelings of awe, wonder, and astonishment as well as appreciation have been largely ignored in the working lives of scientists. In turn, I believe that science education has not accurately portrayed the world of science to our students. In an effort to bring the affective qualities of science into the science classroom, I have drawn on past research in the field of aesthetic science teaching and learning as well as works by, Burke, Kant, and Dewey to explore a new construct I have called the "scientific sublime". Scientific sublime experiences represent a sophisticated treatment of the cognitive as well as affective qualities of science learning. The scientific sublime represents feelings of awe, wonder, and appreciation that come from a deep understanding. It is only through this understanding of a phenomenon that we can appreciate its true complexity and intricacies, and these understandings when mixed with the emotions of awe and reverence, are sublime. Scientific sublime experiences are an attempt at the re-integration of cognition and feeling. The goal of this research was twofold: to create and teach a curriculum that fosters scientific sublime experiences in middle school science classes, and to better understand how these experiences are manifested in students. In order to create an approach to teaching for scientific sublime experiences, it was first necessary for me to identify key characteristics of such an experience and a then to create a pedagogical approach, both of which are described in detail in the dissertation. This research was conducted as two studies in two different middle schools. My pedagogical approach was used to create and teach two five-week 7 th grade science units---one on weather

    Citizen science programs enable community involvement in scientific research. In addition to fostering greater science literacy, some citizen science programs aim to foster engagement in environmental issues. However, few data are available to indicate whether and how citizen science programs can achieve greater environmental engagement. We survey individuals choosing to attend one of seventeen reef citizen science events and examine the extent to which attendees reported three indicators of greater environmental engagement: (i) willingness to share information, (ii) increased support for marine conservation and citizen science, and (iii) intentions to adopt a new behavior. Most participants reported being willing to share information about reef conservation (91%) and described increased support for marine science and conservation (87%). Half of participants (51%) reported intentions to adopt a new conservation behavior. We found that key elements of the citizen science experience associated with these outcomes were learning about actions to protect reefs and coasts (procedural learning), experiencing surprise, and experiencing negative emotions about environmental problems. Excitement was also associated with positive outcomes, but only in participants who were less likely to see themselves as environmental, or were less frequent visitors to reefs and coasts. Importantly, the association between factual learning and environmental engagement outcomes was limited or negative. These findings suggest that the way citizen science experiences make people feel, may be more important for fostering future environmental engagement than factual-based learning. When designing citizen science programs for community members, these findings provide a reminder to not focus on provision of factual information alone, but to highlight environmental impacts while providing meaningful experiences and building environmental skills.

  16. 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

  19. Fair Inference on Outcomes

    PubMed Central

    Nabi, Razieh; Shpitser, Ilya

    2017-01-01

    In this paper, we consider the problem of fair statistical inference involving outcome variables. Examples include classification and regression problems, and estimating treatment effects in randomized trials or observational data. The issue of fairness arises in such problems where some covariates or treatments are “sensitive,” in the sense of having potential of creating discrimination. In this paper, we argue that the presence of discrimination can be formalized in a sensible way as the presence of an effect of a sensitive covariate on the outcome along certain causal pathways, a view which generalizes (Pearl 2009). A fair outcome model can then be learned by solving a constrained optimization problem. We discuss a number of complications that arise in classical statistical inference due to this view and provide workarounds based on recent work in causal and semi-parametric inference.

    Key features of operational plans developed in a study of the Space Shuttle era life science payloads program are presented. The data describes the overall acquisition, staging, and integration of payload elements, as well as program implementation methods and mission support requirements. Five configurations were selected as representative payloads: (a) carry-on laboratories - medical emphasis experiments, (b) mini-laboratories - medical/biology experiments, (c) seven-day dedicated laboratories - medical/biology experiments, (d) 30-day dedicated laboratories - Regenerative Life Support Evaluation (RLSE) with selected life science experiments, and (e) Biomedical Experiments Scientific Satellite (BESS) - extended duration primate (Type I) and small vertebrate (Type II) missions. The recommended operational methods described in the paper are compared to the fundamental data which has been developed in the life science Spacelab Mission Simulation (SMS) test series. Areas assessed include crew training, experiment development and integration, testing, data-dissemination, organization interfaces, and principal investigator working relationships.

  5. The evolution of fairness through spite

    PubMed Central

    Forber, Patrick; Smead, Rory

    2014-01-01

    The presence of apparently irrational fair play in the ultimatum game remains a focal point for studies in the evolution of social behaviour. We investigate the role of negative assortment in the evolution of fair play in the ultimatum game. Spite—social behaviour that inflicts harm with no direct benefit to the actor—can evolve when it is disproportionally directed at individuals playing different strategies. The introduction of negative assortment alters the dynamics in a way that increases the chance fairness evolves, but at a cost: spite also evolves. Fairness is usually linked to cooperation and prosocial behaviour, but this study shows that it may have evolutionary links to harmful antisocial behaviour. PMID:24523265

  1. Research Experiences in Community College Science Programs

    NASA Astrophysics Data System (ADS)

    Beauregard, A.

    2011-12-01

    The benefits of student access to scientific research opportunities and the use of data in curriculum and student inquiry-driven approaches to teaching as effective tools in science instruction are compelling (i.e., Ledley, et al., 2008; Gawel & Greengrove, 2005; Macdonald, et al., 2005; Harnik & Ross. 2003). Unfortunately, these experiences are traditionally limited at community colleges due to heavy faculty teaching loads, a focus on teaching over research, and scarce departmental funds. Without such hands-on learning activities, instructors may find it difficult to stimulate excitement about science in their students, who are typically non-major and nontraditional. I present two different approaches for effectively incorporating research into the community college setting that each rely on partnerships with other institutions. The first of these is a more traditional approach for providing research experiences to undergraduate students, though such experiences are limited at community colleges, and involves student interns working on a research project under the supervision of a faculty member. Specifically, students participate in a water quality assessment study of two local bayous. Students work on different aspects of the project, including water sample collection, bio-assay incubation experiments, water quality sample analysis, and collection and identification of phytoplankton. Over the past four years, nine community college students, as well as two undergraduate students and four graduate students from the local four-year university have participated in this research project. Aligning student and faculty research provides community college students with the unique opportunity to participate in the process of active science and contribute to "real" scientific research. Because students are working in a local watershed, these field experiences provide a valuable "place-based" educational opportunity. The second approach links cutting-edge oceanographic

    In this essay, Amy Voss Farris and Pratim Sengupta argue that a democratic approach to children's computing education in a science class must focus on the "aesthetics" of children's experience. In "Democracy and Education," Dewey links "democracy" with a distinctive understanding of "experience." For Dewey,…

  3. Expanding educational access and opportunities: The globalization and foreign direct investment of multinational corporations and their influence on STEM, project-based learning and the national science and technology fair in schools in Costa Rica

    NASA Astrophysics Data System (ADS)

    Valdez, Joaquin G.

    The purpose of this qualitative study was to examine the influence of globalization and the foreign direct investment (FDI) of multinational corporations (MNCs) on the curriculum in schools in Costa Rica. The study focused primarily on Science, Technology, Engineering and Mathematics (STEM), Project-Based Learning (PBL), 21st century skills, and the national science and technology fair. The high influx of MNCs such as Intel has changed the global and educational culture of the country increasing the number of knowledge-based workers in Costa Rica. As a result, policy changes have been instituted in education to mirror the demands of sustaining the country's global economy. This study was supported by the creation of three research questions that would attempt to answer 1) the extent that teachers implementing STEM curriculum trace their practices back to policy, globalization, and multinational corporations as well as the extent to which the economic growth of Costa Rica and STEM education are related, 2) how mandating the national science and technology fair has influenced 21st century skills through project-based learning and the use of technology by teachers and its impact on curriculum and instruction, and 3) how has the national science and technology fair policy changed the value of STEM education for students, teachers, and educational leaders. To further understand the outcome of this study, four theoretical frameworks were applied that included, Spring's theory of world educational culture, Friedman's world flatteners, Wagner's 21st century skills and partnerships for 21st century skills, and Slough and Milam's STEM project-based learning theoretical framework. Each framework was applied to support the changes to the educational system; survival skills necessary to compete in the global job market; application of 21st century skills in the classroom and in the science projects students created. A research team comprised of 14 doctoral students, led by Dr

  4. The Co-Evolution of Fairness Preferences and Costly Punishment

    Hetzer, Moritz; Sornette, Didier

    2013-01-01

    We study the co-evolutionary emergence of fairness preferences in the form of other-regarding behavior and its effect on the origination of costly punishment behavior in public good games. Our approach closely combines empirical results from three experiments with an evolutionary simulation model. In this way, we try to fill a gap between the evolutionary theoretical literature on cooperation and punishment on the one hand and the empirical findings from experimental economics on the other hand. As a principal result, we show that the evolution among interacting agents inevitably favors a sense for fairness in the form of “disadvantageous inequity aversion”. The evolutionary dominance and stability of disadvantageous inequity aversion is demonstrated by enabling agents to co-evolve with different self- and other-regarding preferences in a competitive environment with limited resources. Disadvantageous inequity aversion leads to the emergence of costly (“altruistic”) punishment behavior and quantitatively explains the level of punishment observed in contemporary lab experiments performed on subjects with a western culture. Our findings corroborate, complement, and interlink the experimental and theoretical literature that has shown the importance of other-regarding behavior in various decision settings. PMID:23526926

  5. Secondhand smoke policies at state and county fairs.

    2010-01-01

    We sought to assess the smoking policies at state and county fairs in North Carolina. We contacted North Carolina fair managers by telephone to solicit participation in a survey that assessed the extent to which fairs have written policies about smoking and secondhand smoke (SHS) exposure, managers' beliefs concerning the health risks associated with SHS exposure, and specific reasons that might prompt managers to adopt smoke-free policies. Attempts were made to contact 47 fair managers, and 37 (66.0%) participated in the study. We found that although almost two-thirds of fairs prohibited smoking indoors, the vast majority (83.9%) had no limits on outdoor smoking. Most fair managers (84.6%) acknowledged that SHS may cause lung cancer, and a majority (51.6%) reported a belief that their patrons would largely be supportive of a more restrictive policy. Fair managers' responses were primarily based on their own opinions, estimates, and attitudes. Because of the high number and density of fair patrons, unrestricted outdoor smoking likely exposes most patrons to SHS. Action to eliminate all exposure to SHS at state and county fairs is needed.

    The Student Spaceflight Experiments Program (SSEP) is a United States national science, technology, engineering, and mathematics initiative that aims to increase student interest in science by offering opportunities to perform spaceflight experiments. The experiment detailed here was selected and flown aboard the third SSEP mission and the first SSEP mission to the International Space Station (ISS). Caenorhabditis elegans is a small, transparent, self-fertilizing hermaphroditic roundworm that is commonly used in biological experiments both on Earth and in Low Earth Orbit. Past experiments have found decreased expression of mRNA for several genes whose expression can be controlled by the FOXO transcription factor DAF-16. We flew a daf-16 mutant and control worms to determine if the effects of spaceflight on C. elegans are mediated by DAF-16. The experiment used a Type Two Fluids Mixing Enclosure (FME), developed by Nanoracks LLC, and was delivered to the ISS aboard the SpaceX Dragon and returned aboard the Russian Soyuz. The short time interval between experiment selection and the flight rendered preflight experiment verification tests impossible. In addition, published research regarding the viability of the FME in life science experiments was not available. The experiment was therefore structured in such a way as to gather the needed data. Here we report that C. elegans can survive relatively short storage and activation in the FME but cannot produce viable populations for post-flight analysis on extended missions. The FME appears to support short-duration life science experiments, potentially on supply or crew exchange missions, but not on longer ISS expeditions. Additionally, the flown FME was not properly activated, reportedly due to a flaw in training procedures. We suggest that a modified transparent FME could prevent similar failures in future flight experiments.

  17. Space Station life sciences guidelines for nonhuman experiment accommodation

    NASA Technical Reports Server (NTRS)

    Arno, R.; Hilchey, J.

    1985-01-01

    Life scientists will utilize one of four habitable modules which constitute the initial Space Station configuration. This module will be initially employed for studies related to nonhuman and human life sciences. At a later date, a new module, devoted entirely to nonhuman life sciences will be launched. This report presents a description of the characteristics of a Space Station laboratory facility from the standpoint of nonhuman research requirements. Attention is given to the science rationale for experiments which support applied medical research and basic gravitational biology, mission profiles and typical equipment and subsystem descriptions, issues associated with the accommodation of nonhuman life sciences on the Space Station, and conceptual designs for the initial operational capability configuration and later Space Station life-sciences research facilities.

  18. Does market competition explain fairness?

    PubMed

    Descioli, Peter

    2013-02-01

    The target article by Baumard et al. uses their previous model of bargaining with outside options to explain fairness and other features of human sociality. This theory implies that fairness judgments are determined by supply and demand but humans often perceive prices (divisions of surplus) in competitive markets to be unfair.

  19. Uncovering the lived experiences of junior and senior undergraduate female science majors

    NASA Astrophysics Data System (ADS)

    Adornato, Philip

    The following dissertation focuses on a case study that uses critical theory, social learning theory, identity theory, liberal feminine theory, and motivation theory to conduct a narrative describing the lived experience of females and their performance in two highly selective private university, where students can cross-register between school, while majoring in science, technology, engineering and mathematics (STEM). Through the use of narratives, the research attempts to shed additional light on the informal and formal science learning experiences that motivates young females to major in STEM in order to help increase the number of women entering STEM careers and retaining women in STEM majors. In the addition to the narratives, surveys were performed to encompass a larger audience while looking for themes and phenomena which explore what captivates and motivates young females' interests in science and continues to nurture and facilitate their growth throughout high school and college, and propel them into a major in STEM in college. The purpose of this study was to uncover the lived experiences of junior and senior undergraduate female science majors during their formal and informal education, their science motivation to learn science, their science identities, and any experiences in gender inequity they may have encountered. The findings have implications for young women deciding on future careers and majors through early exposure and guidance, understanding and recognizing what gender discrimination, and the positive effects of mentorships.

  20. Bell violation using entangled photons without the fair-sampling assumption.

    PubMed

    The violation of a Bell inequality is an experimental observation that forces the abandonment of a local realistic viewpoint--namely, one in which physical properties are (probabilistically) defined before and independently of measurement, and in which no physical influence can propagate faster than the speed of light. All such experimental violations require additional assumptions depending on their specific construction, making them vulnerable to so-called loopholes. Here we use entangled photons to violate a Bell inequality while closing the fair-sampling loophole, that is, without assuming that the sample of measured photons accurately represents the entire ensemble. To do this, we use the Eberhard form of Bell's inequality, which is not vulnerable to the fair-sampling assumption and which allows a lower collection efficiency than other forms. Technical improvements of the photon source and high-efficiency transition-edge sensors were crucial for achieving a sufficiently high collection efficiency. Our experiment makes the photon the first physical system for which each of the main loopholes has been closed, albeit in different experiments.

  1. Operation of MRO's High Resolution Imaging Science Experiment (HiRISE): Maximizing Science Participation

    NASA Technical Reports Server (NTRS)

    Eliason, E.; Hansen, C. J.; McEwen, A.; Delamere, W. A.; Bridges, N.; Grant, J.; Gulich, V.; Herkenhoff, K.; Keszthelyi, L.; Kirk, R.

    Science return from the Mars Reconnaissance Orbiter (MRO) High Resolution Imaging Science Experiment (HiRISE) will be optimized by maximizing science participation in the experiment. MRO is expected to arrive at Mars in March 2006, and the primary science phase begins near the end of 2006 after aerobraking (6 months) and a transition phase. The primary science phase lasts for almost 2 Earth years, followed by a 2-year relay phase in which science observations by MRO are expected to continue. We expect to acquire approx. 10,000 images with HiRISE over the course of MRO's two earth-year mission. HiRISE can acquire images with a ground sampling dimension of as little as 30 cm (from a typical altitude of 300 km), in up to 3 colors, and many targets will be re-imaged for stereo. With such high spatial resolution, the percent coverage of Mars will be very limited in spite of the relatively high data rate of MRO (approx. 10x greater than MGS or Odyssey). We expect to cover approx. 1% of Mars at approx. 1m/pixel or better, approx. 0.1% at full resolution, and approx. 0.05% in color or in stereo. Therefore, the placement of each HiRISE image must be carefully considered in order to maximize the scientific return from MRO. We believe that every observation should be the result of a mini research project based on pre-existing datasets. During operations, we will need a large database of carefully researched 'suggested' observations to select from. The HiRISE team is dedicated to involving the broad Mars community in creating this database, to the fullest degree that is both practical and legal. The philosophy of the team and the design of the ground data system are geared to enabling community involvement. A key aspect of this is that image data will be made available to the planetary community for science analysis as quickly as possible to encourage feedback and new ideas for targets.

  9. The destructiveness of laissez-faire leadership behavior.

    PubMed

    Skogstad, Anders; Einarsen, Ståle; Torsheim, Torbjørn; Aasland, Merethe Schanke; Hetland, Hilde

    2007-01-01

    The aim of the study is to test the assumption that laissez-faire leadership behavior is not a type of zero-leadership, but a type of destructive leadership behavior that shows systematic relationships with workplace stressors, bullying at work, and psychological distress. A survey of 2,273 Norwegian employees was conducted and analyzed. Laissez-faire leadership was positively correlated with role conflict, role ambiguity, and conflicts with coworkers. Path modeling showed that these stressors mediated the effects of laissez-faire leadership on bullying at work and that the effects of laissez-faire leadership on distress were mediated through the workplace stressors, especially through exposure to bullying. The results support the assumption that laissez-faire leadership behavior is a destructive leadership behavior. (c) 2007 APA, all rights reserved.

    Standardized measurement instruments (tests) have become an essential tool in health sciences. The concept of equity in the development, adaptation and administration of psychometric tests was first introduced in "Standards for Educational and Psychological Testing" published in 1999 by the American Educational Research Association, the American Psychological Association, and the National Council on Measurement in Education. Despite its importance, this concept has been scarcely used in epidemiology and public health. Consequently, this methodological note aims to explain the concept of equity in testing and to provide tools and indications to detect and solve their inequitable use. Copyright © 2014 SESPAS.
