Research on same-gender grouping in eighth-grade science classrooms

NASA Astrophysics Data System (ADS)

Friend, Jennifer Ingrid

This study examined two hypotheses related to same-gender grouping of eighth-grade science classes in a public middle-school setting in suburban Kansas City. The first hypothesis, male and female students enrolled in same-gender eighth-grade science classes demonstrate more positive science academic achievement than their male and female peers enrolled in mixed-gender science classes. The second hypothesis, same-gender grouping of students in eighth-grade science has a positive effect on classroom climate. The participants in this study were randomly assigned to class sections of eighth-grade science. The first experimental group was an eighth-grade science class of all-male students (n = 20) taught by a male science teacher. The control group used for comparison to the male same-gender class consisted of the male students (n = 42) in the coeducational eighth-grade science classes taught by the same male teacher. The second experimental group was an eighth-grade science class of all-female students (n = 23) taught by a female science teacher. The control group for the female same-gender class consisted of female students (n = 61) in the coeducational eighth-grade science classes taught by the same female teacher. The male teacher and the female teacher did not vary instruction for the same-gender and mixed-gender classes. Science academic achievement was measured for both groups through a quantitative analysis using grades on science classroom assessment and overall science course grades. Classroom climate was measured through qualitative observations and through qualitative and quantitative analysis of a twenty-question student survey administered at the end of each trimester grading period. The results of this study did not indicate support for either hypothesis. Data led to the conclusions that same-gender grouping did not produce significant differences in student science academic achievement, and that same-gender classes did not create a more positive

SETI from the moon: an invitation to COSPAR

NASA Astrophysics Data System (ADS)

Heidmann, J.

After presenting arguments for SETI (Search for ExtraTerrestrial Intelligence) work to be done well into the 21st century, and in view of the dramatic increase of blinding human-made radiofrequency interference, this author proposed that a well defined locale on the farside of the Moon - crater Saha - be preserved for the next 20-30 years not only for SETI but also for future high-sensitivity radioastronomy. The long-term programmatic issues were presented at the Lunar Exploration Symposium of the Jerusalem 1994 International Astronautical Federation Congress. The legal questions raised were delineated at the International Institute of Space Law (IISL) Colloquium of the same Jerusalem Congress. Numerous suggestions were given for an action strategy, in particular to present a proposal at a COSPAR venue. In the words of IISL Director A.A. Cocca: ``This reservation of a lunar zone for scientific activities, and its further utilization aiming at the common good of humanity, must be recognized, and constitutes a precedent.'' At the Hamburg 1995 European Geophysical Society XXth GA, we pointed out that this Saha project could offer interesting possibilities for a symbiosis with the `Science on the Moon Exobiology' teams. We also presented it at the Berlin 1996 European Space Agency/Deutsche Forschungsanstalt für Luft und Raumfahrt `International Moon Workshop' to geologists and to bioastrononomers at the Capri 1996 Bioastronomy International Astronomical Union Colloquium #161. At the 1995 IAF Congress in Oslo, the SETI Committee of the International Academy of Astronautics took action for the future benefit of humankind by setting-up a Sub-committee for `A SETI Lunar Study', chaired by the author. We hope that, in view of these initial endeavors, COSPAR may become interested in this Saha proposal and supports it.

Gobron, Nadine; Ollier, Gilles

The Group on Earth Observations is coordinating efforts to build a Global Earth Observation System of Systems, or GEOSS. GEO is a voluntary partnership of governments and inter-national organizations. It provides a framework within which these partners can develop new projects and coordinate their strategies and investments. The Science and Technology Commit-tee of GEO is working to strengthen this role by encouraging the wider scientific and technology community to participate as contributors to and benefactors of a sustained GEOSS. The proposed round table aims at discussing how are scientists and GEO currently working together, using specific examples and how do space agencies or data providers contribute to GEO? Round table participants are welcome to present their own vision on future actions to improve, if necessary, the relations between contributors and GEO. Meeting participants will also be offered the opportunity to intervene and ask questions to the panel. Moderators: • Dr. Nadine Gobron -EC-JRC -Chair of Commission A • Gilles Ollier -DG Research Participants: • Prof. José Achache -Director of GEO • Prof. Maurice Bonnet -President of COSPAR • Dr. Tamatsu Igarashi -JAXA EORC Manager • Dr. Stuart Minchin (CSIRO and member of GEO STC) TBC • Prof. Berrien Moore -Executive Director of Climate Central • Dr. Diane E.

Report from ILEWG to the COSPAR Panel on Exploration

NASA Astrophysics Data System (ADS)

Foing, Bernard H.

The International Lunar Exploration Working Group (ILEWG) was established in April 1995 at a meeting in Hamburg, Germany. As established in its charter, this working group reports to COSPAR and is charged with developing an international strategy for the exploration of the Moon. It discusses coordination between missions, and a road map for future international lunar exploration and utilisation. It fosters information exchange or potential and real future lunar robotic and human missions, as well as for new scientific and exploration information about the Moon. ILEWG was used to feed forward results from lunar missions such as SMART1 to the next ones, and we look now to integrate lessons from all recent orbiters and landers, for the upcoming landers, sample return missions, and human activities. We give a report on ILEWG community activities, refer to COSPAR and ILEWG ICEUM and lunar conferences and declarations [1-18], and discuss the follow-up of GLUC/ICEUM11 declaration relevant to COSPAR PEX*.

We examined the impact of work presented in the plenary sessions at the meeting of The American Association for Thoracic Surgery (AATS), by determining how frequently the published papers corresponding to the session presentations during the past 20 years, were cited; those that were most cited were identified. We reviewed the AATS meeting programs from the 20-year period from 1994 to 2014 and identified the corresponding publications in the Journal of Thoracic and Cardiovascular Surgery (JTCVS) from all abstracts presented at the plenary sessions. Papers were categorized as cardiac, thoracic, or congenital. References were evaluated for subsequent citation in the Web of Science (WoS), and Google Scholar (GS). We determined both the median number of citations overall, and per year. For comparison, we evaluated numbers of citations in WoS from current JTCVS papers in issues containing the 3 most-cited plenary session papers. Among 195 published plenary papers, the median number of citations in WoS and GS was 49 and 76, respectively. The median total number of citations in WoS was as follows: 51 for cardiac-category papers (n = 105); 61 for thoracic (n = 55), and 41 for congenital (n = 35). These values were higher than the median total number of citations for contemporary nonplenary JTCVS papers: cardiac (22, n = 55; P < .001); thoracic (31.5, n = 8; P = .183); and congenital (15.5, n = 24; P = .002) papers published in JTCVS. The median number of citations per year since publication for plenary publications was 5.9 (cardiac), 6 (thoracic), and 3.7 (congenital), respectively. Publications corresponding to the plenary sessions of the AATS are highly cited and include some of the seminal studies in our field in the past 20 years.

Contributing to COSPAR - Contibuting to Expanding the Knowledge Frontier of Space for the Benefit of Humankind

NASA Astrophysics Data System (ADS)

Lopez-Baeza, Ernesto

COSPAR's objectives are to promote -on an international level- scientific research in space, with emphasis on the exchange of results, information and opinions, and to provide a forum, open to all scientists, for the discussion of problems that may affect scientific space research (https://cosparhq.cnes.fr/about/origin-purpose-role). COSPAR played an extraordinary significant role in the past by facilitating the scientific exchange between East and West … and surely contributed to the present fluid and free-flowding situation. COSPAR’s challenge now is to get a similar result by providing opportunities to less developed countries to upgrade their resources to progress on all kinds of research using space means. This presentation shows the activity developed by the Climatology from Satellites Group of the University of Valencia, Spain, during the last 10 years, in different action areas of COSPAR, and in the framework of Commission A on Space Studies of the Earth's Surface, Meteorology and Climate, especially in Sub-Commission A3 on Land Processes and Morphology, as well as in the organisation of some Capacity Building Courses akin to Commission A’s terms of reference. The effort -if any- has always and so far been worthwhile. The Group has learnt a lot, it has notably incresed its capacity for networking, as well as its opportunities to accompany scientists from less developed countries in their scientific growing and development of resources (Give a man a fish and you feed him for a day. Teach a man to fish and you feed him for a lifetime -Chinese proverb … and root and foundation for Capacity Building).

...The Bureau of Industry and Security (BIS) maintains, as part of its Export Administration Regulations (EAR), the Commerce Control List (CCL), which identifies certain of the items subject to Department of Commerce jurisdiction. This final rule revises the CCL to implement changes made to the Wassenaar Arrangement's List of Dual-Use Goods and Technologies (Wassenaar List) maintained and agreed to by governments participating in the Wassenaar Arrangement on Export Controls for Conventional Arms and Dual-Use Goods and Technologies (Wassenaar Arrangement, or WA) at the December 2012 WA Plenary Meeting (the Plenary). The Wassenaar Arrangement advocates implementation of effective export controls on strategic items with the objective of improving regional and international security and stability. This rule harmonizes the CCL with the changes made to the WA List at the Plenary by revising ECCNs controlled for national security reasons in each category of the CCL, except category 8, as well as amending the General Software Note, WA reporting requirements, and definitions section in the EAR. BIS is adding unilateral controls to the CCL for specific software and technology for aviation control systems, which the WA agreements removed from the WA List, i.e., EAR national security controls.

We measured the potential impact of articles representing the International Symposium on Veterinary Epidemiology and Economics (ISVEE) plenary-session presentations in subsequent published literature. Between July 1, 2004 and November 9, 2004, we searched the Web of Science for citations in the scientific literature to all 99 plenary-session articles published in the proceedings of the previous nine ISVEEs (or in journal special issues dedicated to the ISVEE plenary articles). We used a 4-year window around the publication of each of the ISVEE proceedings. We located 187 citations for 37 (of the 99) articles. We infer that the ISVEE proceedings represent an important resource for veterinary epidemiology.

Investigating everyday measures through exploratory talk: whole class plenary intervention and landscape study at grade four

NASA Astrophysics Data System (ADS)

Gade, Sharada; Blomqvist, Charlotta

2018-03-01

We report an exploratory talk based, whole class plenary intervention, in relation to students' understanding of everyday measures and measurement, in a grade four classroom at a grade 4-6 school in Sweden. Extended, project related, teacher-researcher collaboration forms basis for such cultural historical activity theory or CHAT based efforts. As formative intervention, the conduct of the plenary is not pre-determined but embedded in ongoing curricular realities, with the agency of students and teacher promoted, pedagogical ideas reutilised and the role of researcher viewed as supporting design and growth of the intervention. Under Charlotta's guidance as teacher, the plenary is opportunity for her students to examine improbable scenarios such as, Can Eva and Anton measure the length of Sweden on foot, Can Lars and Iris measure their age in decimeters. A zone of proximal development is created, in which students make the transition from spontaneous to scientific concepts and learn how various units of measurement are objects-that-can-be-used-for-certain-purposes. With opportunity for critical and reflective inquiry, in a plenary designed to lead development, Charlotta's students look beyond the making of rote measurements and articulate a theory of measure in nascent terms. Such a landscape of teaching-learning is finally understood in terms of the nature of talk that was facilitated, the manner of pedagogy utilised, the style of teaching exercised and the kind of learning that was demanded of her students.

The closing plenary of the colloquium was an occasion for exchange between the four panelists and the participants. The panelists included Luc Berghmans, a doctor and director of the regional health observatory of Hainaut, Belgium; Louise Bouchard, a sociologist and professor in the Sociology and Anthropology Department, University of Ottawa, Canada; Michel O’Neill, a sociologist and professor at the Faculty of Nursing Sciences, Laval University, Quebec City, Canada; and Philippe Lorenzo, director general of IREPS, the regional bureau for health education and promotion of Picardie in Amiens, France. Louise Potvin, who moderated the plenary, provides the summary that follows. During the colloquium, three main questions were debated: 1. At what point should health be placed at the forefront of local actions, if we wish to promote the values of equity? 2. How should actions at the local, regional, national and global levels be organized and articulated? Who are the partners, and what forms of governance need to be put into place? 3. What are the parameters needed in order to define the roles, tasks and competencies of the implementers of local and regional health programs, the architects of change? Each panelist had to respond to two out of the three questions. We report on the answers that panelists gave to these questions. As it is impossible to verify the exactitude of information given by audience members in support of their viewpoints, only the content of the remarks is given, without mentioning the examples that were provided.

Gabriel, C.

2016-08-01

The provision of scientific data archives and analysis tools by diverse institutions in the world represents a unique opportunity for the development of scientific activities. An example of this is the European Space Agency's space observatory XMM-Newton with its Science Operations Centre at the European Space Astronomy Centre near Madrid, Spain. It provides through its science archive and web pages, not only the raw and processed data from the mission, but also analysis tools, and full documentation greatly helping their dissemination and use. These data and tools, freely accesible to anyone in the world, are the practical elements around which COSPAR (COmmittee on SPAce Research) Capacity Building Workshops have been conceived and developed, and held for a decade and a half in developing countries. The Programme started with X-ray workshops, but in-between it has been broadened to the most diverse space science areas. The workshops help to develop science at the highest level in those countries, in a long and substainable way, with a minimal investment (computer plus a moderate Internet connection). In this paper we discuss the basis, concepts, and achievements of the Capacity Building Programme. Two instances of the Programme have already taken place in Argentina, one of them devoted to X-ray astronomy and another to Infrared Astronomy. Several others have been organised for the Latin American region (Brazil, Uruguay and Mexico) with a large participation of young investigators from Argentina.

The goal of the eighth industrial fluid properties simulation challenge was to test the ability of molecular simulation methods to predict the adsorption of organic adsorbates in activated carbon materials. In particular, the eighth challenge focused on the adsorption of perfluorohexane in the activated carbon BAM-109. Entrants were challenged to predict the adsorption in the carbon at 273 K and relative pressures of 0.1, 0.3, and 0.6. The predictions were judged by comparison to a benchmark set of experimentally determined values. Overall good agreement and consistency were found between the predictions of most entrants.

Algebra for All: California's Eighth-Grade Algebra Initiative as Constrained Curricula.

Domina, Thurston; Penner, Andrew M; Penner, Emily K; Conley, Annemarie

2014-08-01

Across the United States, secondary school curricula are intensifying as a growing proportion of students enroll in high-level academic math courses. In many districts, this intensification process occurs as early as eighth grade, where schools are effectively constraining their mathematics curricula by restricting course offerings and placing more students into Algebra I. This paper provides a quantitative single-case research study of policy-driven curricular intensification in one California school district. (1a) What effect did 8th eighth grade curricular intensification have on mathematics course enrollment patterns in Towering Pines Unified schools? (2b) How did the distribution of prior achievement in Towering Pines math classrooms change as the district constrained the curriculum by universalizing 8th eighth grade Algebra? (3c) Did 8th eighth grade curricular intensification improve students' mathematics achievement? Towering Pines is an immigrant enclave in the inner-ring suburbs of a major metropolitan area. The district's 10 middle schools together enroll approximately 4,000 eighth graders each year. The districts' students are ethnically diverse and largely economically disadvantaged. The study draws upon administrative data describing 8th eighth graders in the district in the 2004-20-05 through 2007-20-08 school years. During the study period, Towering Pines dramatically intensified middle school students' math curricula: In the 2004-20-05 school year 32% of the district's 8th eighth graders enrolled in Algebra or a higher- level mathematics course; by the 2007-20-08 school year that proportion had increased to 84%. We use an interrupted time-series design, comparing students' 8th eighth grade math course enrollments, 10th grade math course enrollments, and 10th grade math test scores across the four cohorts, controlling for demographics and prior achievement. We find that students' odds of taking higher level mathematics courses increased as this

Consistent with the International Psycho-Oncology Society's (IPOS) vision and goals, we are committed to improving quality cancer care and cancer policies through psychosocial care globally. As part of IPOS's mission, upon entering "Official Relations" for a second term with the World Health Organization (WHO), IPOS has dedicated much attention to reaching out to countries, which lack formalized psychosocial care programmes. One of IPOS's strategies to accomplish this goal has been to bring psycho-oncology training programmes to low- and middle-income countries and regions. To this end, the IPOS Board approved a new position on the Board of Directors for a member from a low- to middle-income country (LMIC). The IPOS 2016 President's Plenary focused on challenges and opportunities that exist in growing and developing psychosocial oncology programmes worldwide. The plenary presentations highlight how IPOS and WHO have aligned their goals to help LMICs support cancer patients as an essential element of cancer and palliative care. IPOS country representatives are strongly supported in liaising with national health authorities and with WHO Country Representatives in LMICs. The plenary speakers discussed the role IPOS Federation has taken in building a global network of psychosocial leaders and the impact this had in assisting LMICs in meeting IPOS's psychosocial care objectives.

At the time of the COSPAR General Assembly in Moscow, the 21st workshop of the Programme for Capacity Building will have taken place. We have started in 2001 with the aim of: i) increasing the knowledge and use of public archives of space data in developing countries, ii) providing highly-practical instruction in the use of these archives and the associated publicly-available software, and iii) fostering personal links between participants and the experienced scientists who lecture during the workshops and supervise the projects carried on by the students. Workshops in many space disciplines have been successfully held so far (X-ray, Gamma-ray and Space Optical and UV Astronomy, Magnetospheric Physics, Space Oceanography, Remote Sensing and Planetary Science) in thirteen countries (Argentina, Brazil, China, Egypt, India, Indonesia, Malaysia, Morocco, Romania, Russia, South Africa, Thailand and Uruguay). An associated Fellowship Programme is helping former participants of these workshops to build on skills gained at them. We will summarize the past and discuss the present and future of the Programme, including highlights like the most recent one: the identification of a transient magnetar (the 9th object of this class so far discovered) in the vicinity of a supernova by one of our students, during the CB workshop on high-energy Astrophysics in Xuyi, China, in September 2013.

Algebra for All: California’s Eighth-Grade Algebra Initiative as Constrained Curricula

2015-01-01

Background/Context Across the United States, secondary school curricula are intensifying as a growing proportion of students enroll in high-level academic math courses. In many districts, this intensification process occurs as early as eighth grade, where schools are effectively constraining their mathematics curricula by restricting course offerings and placing more students into Algebra I. This paper provides a quantitative single-case research study of policy-driven curricular intensification in one California school district. Research Questions (1a) What effect did 8th eighth grade curricular intensification have on mathematics course enrollment patterns in Towering Pines Unified schools? (2b) How did the distribution of prior achievement in Towering Pines math classrooms change as the district constrained the curriculum by universalizing 8th eighth grade Algebra? (3c) Did 8th eighth grade curricular intensification improve students’ mathematics achievement? Setting Towering Pines is an immigrant enclave in the inner-ring suburbs of a major metropolitan area. The district’s 10 middle schools together enroll approximately 4,000 eighth graders each year. The districts’ students are ethnically diverse and largely economically disadvantaged. The study draws upon administrative data describing 8th eighth graders in the district in the 2004–20-05 through 2007–20-08 school years. Intervention/Program/Practice During the study period, Towering Pines dramatically intensified middle school students’ math curricula: In the 2004–20-05 school year 32% of the district’s 8th eighth graders enrolled in Algebra or a higher- level mathematics course; by the 2007–20-08 school year that proportion had increased to 84%. Research Design We use an interrupted time-series design, comparing students’ 8th eighth grade math course enrollments, 10th grade math course enrollments, and 10th grade math test scores across the four cohorts, controlling for demographics and

School Breakfast Receipt and Obesity among American Fifth- and Eighth-Graders.

PubMed

Sudharsanan, Nikkil; Romano, Sebastian; Cunningham, Solveig A

2016-04-01

School breakfast consumption can improve children's nutrition, but the implications of breakfast at school for children's weight remains unclear. The aim of this study was to determine whether receiving breakfast at school is related to changes in children's weight between the fifth and eighth grades, and whether the relationship between school breakfasts and obesity varies for children of different socioeconomic backgrounds. This was a longitudinal study of children observed in the fifth and eighth grades. Data are from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99, a nationally representative prospective cohort of children in the United States. The analytic sample consisted of 6,495 children interviewed in the fifth and eighth grades. Standard thresholds from the Centers for Disease Control and Prevention were used to classify children as not obese or obese based on direct-measured height and weight. Difference-in-difference propensity score matching and fixed-effect logistic regression models were used to estimate the relationship between receipt of school breakfast and change in obesity between the fifth and eighth grades, adjusting for child, household, and school characteristics. School breakfast receipt was not associated with a change in obesity status between the fifth and eighth grades for children overall (odds ratio=1.31; P=0.129). In the propensity score model, receiving school breakfasts more than doubled the odds of becoming obese (odds ratio=2.31; P=0.0108) for children from families below the federal poverty line compared with children of similar socioeconomic backgrounds who did not regularly receive school breakfasts. School breakfast receipt was not independently related to obesity for most children. Receiving school breakfasts in the fifth grade may be associated with weight gain between the fifth and eighth grades for children from families below the federal poverty line compared with children of similar socioeconomic

Eighth Grade Algebra Course Placement and Student Motivation for Mathematics

PubMed Central

Simzar, Rahila M.; Domina, Thurston; Tran, Cathy

2016-01-01

This study uses student panel data to examine the association between Algebra placement and student motivation for mathematics. Changes in achievement goals, expectancy, and task value for students in eighth grade Algebra are compared with those of peers placed in lower-level mathematics courses (N = 3,306). In our sample, students placed in Algebra reported an increase in performance-avoidance goals as well as decreases in academic self-efficacy and task value. These relations were attenuated for students who had high mathematics achievement prior to Algebra placement. Whereas all students reported an overall decline in performance-approach goals over the course of eighth grade, previously high-achieving students reported an increase in these goals. Lastly, previously high-achieving students reported an increase in mastery goals. These findings suggest that while previously high-achieving students may benefit motivationally from eighth grade Algebra placement, placing previously average- and low-performing students in Algebra can potentially undermine their motivation for mathematics.

2013-06-01

The objective of our study was to analyze plenary abstracts since 2006, when the Association for Academic Surgery (AAS) and Society of University Surgeons (SUS) began hosting the combined annual Academic Surgical Congress (ASC). Plenary session abstracts from the separate AAS and SUS meetings from 2002 to 2004 had previously revealed no significant difference in the scientific impact of published manuscripts. In total, 76 abstracts from the AAS (n = 40) and SUS (n = 36) plenary sessions at the annual ASC meetings (2006-2010) were reviewed. Publication rate, citation number, 2010 impact factor (IF), and 5-y IF were obtained. Statistical analysis was conducted using Fisher exact and Student t-tests. Overall, 60 (79%) of 76 ASC plenary abstracts presented between 2006 and 2010 were published in peer-reviewed journals. Analysis revealed a higher publication rate for AAS (90%) compared with SUS (67%) plenary abstracts (P = 0.02). Among the articles published, the overall mean number of total citations was 6.7, with no difference between AAS and SUS (5.9 versus 7.8, P = 0.46). The mean 2010 five-year IF for all publications was 4.6 (AAS, 4.3 versus SUS, 5.0; P = 0.54). Compared with a previous analysis from the separate meetings, the mean IF has increased for both societies at an equivalent rate of 0.4. After the initiation of the joint ASC meeting in 2006, the SUS and AAS plenary presentations continue to exhibit high-quality research. This study supports the benefit of a joint meeting for the AAS and SUS, as it has been associated with an increasing overall scientific impact for plenary abstracts. Copyright © 2013 Elsevier Inc.

Predictors of beer advertising awareness among eighth graders.

PubMed

Collins, Rebecca L; Schell, Terry; Ellickson, Phyllis L; McCaffrey, Daniel

2003-09-01

To identify correlates of beer advertising awareness among adolescents at an age when most initiate use of alcohol. We conducted a cross-sectional analysis of an in-school survey about alcohol advertising. Structural equation modeling was used to test for independent predictors of a latent beer advertising awareness construct, separately among boys and girls. Twenty middle schools in South Dakota, USA participated during their spring semester. A total of 1530 eighth graders. A latent advertisement awareness variable was derived based on recognition of six masked beer advertisements, knowledge of beer brands and knowledge of beer slogans. Tested predictors included measures of exposure to alcohol advertising in various venues, social norms regarding drinking, drinking beliefs and behavior and gender. Adolescents with greater exposure to advertisements in magazines, at sporting and music events and on television were more advertisement aware than those with less exposure, as were teens who watch more TV, pay attention to beer advertisements and know adults who drink. Beer advertisement awareness was dramatically higher among boys, and was associated with drinking only among boys. Each of a variety of advertising venues appears to influence independently the extent to which beer advertising is incorporated into an adolescent's cognitive world. Boys are more likely to be aware of and remember beer marketing, and may be more likely to drink as a result of this awareness than girls.

Sixth- and eighth-order Hermite integrator for N-body simulations

NASA Astrophysics Data System (ADS)

Nitadori, Keigo; Makino, Junichiro

2008-10-01

We present sixth- and eighth-order Hermite integrators for astrophysical N-body simulations, which use the derivatives of accelerations up to second-order ( snap) and third-order ( crackle). These schemes do not require previous values for the corrector, and require only one previous value to construct the predictor. Thus, they are fairly easy to implement. The additional cost of the calculation of the higher-order derivatives is not very high. Even for the eighth-order scheme, the number of floating-point operations for force calculation is only about two times larger than that for traditional fourth-order Hermite scheme. The sixth-order scheme is better than the traditional fourth-order scheme for most cases. When the required accuracy is very high, the eighth-order one is the best. These high-order schemes have several practical advantages. For example, they allow a larger number of particles to be integrated in parallel than the fourth-order scheme does, resulting in higher execution efficiency in both general-purpose parallel computers and GRAPE systems.

Shaklan, Stuart B.; Green, Joseph J.

2005-01-01

In a recent paper, Kuchner, Crepp, and Ge describe new image-plane coronagraph mask designs that reject to eighth order the leakage of starlight caused by image motion at the mask, resulting in a substantial relaxation of image centroiding requirements compared to previous fourth-order and second-order masks. They also suggest that the new masks are effective at rejecting leakage caused by low-order aberrations (e.g., focus, coma, and astigmatism). In this paper, we derive the sensitivity of eighth-order masks to aberrations of any order and provide simulations of coronagraph behavior in the presence of optical aberrations.We find that the masks leak light as the fourth power of focus, astigmatism, coma, and trefoil. This has tremendous performance advantages for the Terrestrial Planet Finder Coronagraph.

Central projections of the lateral line and eighth nerves in the bowfin, Amia calva.

PubMed

McCormick, C A

1981-03-20

The first-order connections of the anterior and posterior lateral line nerves and of the eighth nerve were determined in the bowfin, Amia calva, using experimental degeneration and anterograde HRP transport techniques. The termination sites of these nerves define a dorsal lateralis cell column and a ventral octavus cell column. The anterior and posterior lateralis nerves distribute ipsilaterally to two medullary nuclei-nucleus medialis and nucleus caudalis. Nucleus medialis comprises the rostral two-thirds of the lateralis column and contains large, Purkinje-like cells dorsally and polygonal, granule, and fusiform cells ventrally. Nucleus caudalis is located posterior to nucleus medialis and consists of small, granule cells. Anterior lateralis fibers terminate ventrally to ventromedially in both nucleus medialis and nucleus caudalis. Posterior lateralis fibers terminate dorsally to dorsolaterally within these two nuclei. A sparse anterior lateralis input may also be present on the dendrites of one of the nuclei within the octavus cell column, nucleus magnocellularis. In contrast, the anterior and posterior rami of the eighth nerve each terminate within four medullary nuclei which comprise the octavus cell column: the anterior, magnocellular, descending, and posterior octavus nuclei. An eighth nerve projection to the medial reticular formation is also present. Some fibers of the lateralis and eighth nerves terminate within the ipsilateral eminentia granularis of the cerebellum. Lateralis fibers distribute to approximately the lateral half of this structure with posterior lateral line fibers terminating laterally and anterior lateral line fibers terminating medially. Eighth nerve fibers distribute to the medial half of the eminentia granularis.

Examining the Relationship of Textbooks and Labs on Student Achievement in Eighth-Grade Science

NASA Astrophysics Data System (ADS)

Sugalan, Anacita Noromor

One of the most important objectives of teachers, parents, school administrators, and students is to improve student scores on standardized tests such as the State of Texas Assessment for Academic Readiness (STAAR) in eighth-grade science. This quasi experimental study examined the science achievement scores between schools that use textbooks and labs when delivering instruction. This study utilized a quantitative approach using archival data and survey design. Analysis of covariance (ANCOVA) and multiple regression were used to analyze the data while controlling STAAR eighth-grade reading scores to reveal significant differences between classes. The sample and population for this study were predominantly eighth-grade Hispanic students in South Texas. Analysis of covariance showed that classes that used high labs got higher science scores and that the reading scores were significantly related to science scores. Multiple regression findings indicated that textbooks and labs were significant predictors of student achievement on the STAAR eighth- grade science class result in South Texas for Spring 2015. The findings of this study may serve as a catalyst for improving student achievement in science through changes in textbook adoption and doing labs in science. The result suggests the need to research further to investigate other contributing factors of student achievement.

Cross-sectional repeated-measures study. NH, five separate sessions, in 2010 and 2011. 101 NH eighth grade students. Participants answered questions derived from OTC drug facts labels that assessed OTC medication safe use and literacy before and after a student pharmacist-led presentation describing each section of the labels. Participant use of OTC medications, whether participants interpreted OTC drug facts labels correctly, and whether participants were able to identify safe use of OTC medications before and after instruction about OTC drug facts labels. 57% of participants reported taking OTC medications in the previous month, 22% reported taking OTC medications autonomously, and 43% reported checking with a trusted adult before self-administration. After student pharmacist-led education, significant improvements were seen in identifying product indications, calculating adult doses, interpreting adverse effects, knowing when to call a medical provider, understanding proper medication storage, identifying expiration dates, and identifying duplicate medications in products. NH eighth graders were self-medicating with OTC medications. Significant improvements in OTC medication label literacy were seen after student pharmacist-led education. These results provide evidence of the need for, and positive effects of, OTC medication education among U.S. adolescents.

We discuss how lunar missions SMART-1, Kaguya, Chang'E1&2, Chandrayaan-1, LCROSS, LRO, GRAIL, LADEE, Chang'E3 and upcoming missions contribute to lunar exploration objectives & roadmap. We present the GLUC/ICEUM11 declaration and give a report on ongoing relevant ILEWG community activities, with focus on: “1. Science and exploration - World-wide access to raw and derived (geophysical units) data products using consistent formats and coordinate systems will maximize return on investment. We call to develop and implement plans for generation, validation, and release of these data products. Data should be made available for scientific analysis and supporting the development and planning of future missions - There are still Outstanding Questions: Structure and composition of crust, mantle, and core and implications for the origin and evolution of the Earth-Moon system; Timing, origin, and consequences of late heavy bombardment; Impact processes and regolith evolution; Nature and origin of volatile emplacement; Implications for resource utilization. These questions require international cooperation and sharing of results in order to be answered in a cost-effective manner - Ground truth information on the lunar far side is missing and needed to address many important scientific questions, e.g. with a sample return from South Pole-Aitken Basin - Knowledge of the interior is poor relative to the surface, and is needed to address a number of key questions, e.g. with International Lunar Network for seismometry and other geophysical measurements - Lunar missions will be driven by exploration, resource utilization, and science; we should consider minimum science payload for every mission, e.g., landers and rovers should carry instruments to determine surface composition and mineralogy - It is felt important to have a shared database about previous missions available for free, so as to provide

African American eighth-grade female students' perceptions and experiences as learners of science literacy

NASA Astrophysics Data System (ADS)

Crim, Sharan R.

The National Assessment of Educational Progress (2000) reports an achievement gap between male and female students and majority and minority students in science literacy. Rutherford and Algren (2000) describe a scientifically literate person as one who is aware that science, mathematics, and technology are interdependent human enterprises with strengths and limitations; understands key concepts and principles of science; is familiar with the natural world and recognizes both its diversity and unity; and uses scientific knowledge and scientific ways of thinking for individual and social purposes. The purpose of this qualitative case study research was to investigate African American eighth grade female students' perceptions and experiences as learners of science literacy. A social learning theory (Bandura, 1986) and constructivist theory (Vygotsky, 1977) served as a guide for the researcher. Two questions were explored: (1) What are African American eighth grade female students' perceptions and experiences as learners of science literacy? (2) In what ways do the perceptions and experiences of African American eighth grade female students influence their learning of science literacy? Purposeful sampling (Merriam, 1998) was used with four African American eighth grade female students selected as participants for the study. Data collection and analysis occurred between February and August in a single year. Data sources included an open-ended questionnaire, two in-depth interviews with each participant (Seidman, 1991); classroom observations, participant reflective journals, student artifacts, and a researcher's log. Data were analyzed through the constant comparative method (Glaser & Strauss, 1967), and richly descriptive participant portraits and qualitative case studies (Merriam, 1998) were used to report the findings. Three themes emerged from the study that positively affected the perceptions and experiences of African American eighth grade female students as

To examine "travel by walking" (TBW) before and after school among eighth-grade girls. Participants attended 36 middle schools from Arizona, Maryland, Minnesota, Louisiana, California, and South Carolina participating in the Trial of Activity for Adolescent Girls. The cross-sectional sample consisted of 3,076 eighth-grade girls, and the longitudinal sample included 1,017 girls who participated in both sixth and eighth grades. Before- or after-school TBW status was determined from the 3-Day Physical Activity Recall. The main outcomes were body mass index and physical activity, which was measured by accelerometry, estimated for total physical activity (light, moderate, vigorous) and moderate-to-vigorous physical activity (MVPA). Eighth-grade girls who reported TBW had 4 more minutes (95% confidence interval = 2.1-6.1) of MVPA before and after school than nonwalkers, and 2 more minutes of MVPA (95% confidence interval = 1.1-3.1) on an average weekday. In the longitudinal sample, girls who reported TBW before and after school in both sixth and eighth grades (consistent walkers) accumulated more minutes of MVPA for an average weekday than inconsistent walkers in both sixth (27 ± 2.2 vs. 25 ± 1.9 minutes; p = .03) and eighth (28 ± 2.6 vs. 25 ± 2.3 minutes; p = .003) grades. There were no differences in body mass index by walking status. Adolescent girls who reported TBW before and after school accumulated more minutes of MVPA than nonwalkers. Efforts to prevent the decline in walking to school in middle school girls could contribute to their overall physical activity. Copyright © 2012 Society for Adolescent Health and Medicine.

Kindergarten predictors of second versus eighth grade reading comprehension impairments.

PubMed

Adlof, Suzanne M; Catts, Hugh W; Lee, Jaehoon

2010-01-01

Multiple studies have shown that kindergarten measures of phonological awareness and alphabet knowledge are good predictors of reading achievement in the primary grades. However, less attention has been given to the early predictors of later reading achievement. This study used a modified best-subsets variable-selection technique to examine kindergarten predictors of early versus later reading comprehension impairments. Participants included 433 children involved in a longitudinal study of language and reading development. The kindergarten test battery assessed various language skills in addition to phonological awareness, alphabet knowledge, naming speed, and nonverbal cognitive ability. Reading comprehension was assessed in second and eighth grades. Results indicated that different combinations of variables were required to optimally predict second versus eighth grade reading impairments. Although some variables effectively predicted reading impairments in both grades, their relative contributions shifted over time. These results are discussed in light of the changing nature of reading comprehension over time. Further research will help to improve the early identification of later reading disabilities.

Adding insult to injury?: the untoward impact of requiring more than de minimis injury in an Eighth Amendment excessive force case.

PubMed

Hoffman, Robyn D

2009-05-01

This Note explores the conflict over whether a prisoner must suffer more than de minimis injury to sustain an Eighth Amendment excessive force claim. It examines this conflict against the backdrop of the various standards the U.S. Supreme Court adopted in its Eighth Amendment prison conditions jurisprudence between 1976 and 1992, principally focusing on the 1992 Hudson v. McMillian decision. Moreover, this Note considers the intersection of "the evolving standards of decency," the "hands-off doctrine," and the Eighth Amendment injury requirement. Ultimately, this Note advocates that excessive force--when meted out as punishment--violates the Eighth Amendment's prohibition on cruel and unusual punishment regardless of whether a prisoner's injuries are more than de minimis.

Fourth and eighth grade students' conceptions of energy flow through ecosystems

NASA Astrophysics Data System (ADS)

Arkwright, Ashlie Beals

This mixed methods status study examined 32 fourth grade students' conceptual understandings of energy flow through ecosystems prior to instruction and 40 eighth grade students' conceptual understandings of the same topic after five years of daily standards-based instruction in science. Specific ecological concepts assessed related to: 1) roles of organisms; 2) the sun as the original energy source for most ecosystems; and 3) interdependency of organisms. Fourth and eighth grade students were assessed using the same three-tiered forced-choice instrument, with accompanying tasks for students to defend their forced-choice selections and rate their level of confidence in making the selections. The instrument was developed for the study by a team of researchers and was based on similar tasks presented in the research literature. Distractor options were embedded in each assessment task using common non-scientific ideas also reported in the research literature. Cronbach's alpha values at or greater than .992 for each task indicated interrater consistency of task answers, and Rasch analysis was employed to establish the reliability of the instrument. Qualitative and quantitative analyses were employed to assess the data. Constant comparative methods were employed to analyze students' written responses, which were coded and grouped into emerging themes. These themes were further developed to characterize students' conceptual understandings. Student open responses also were scored and coded by a team of researchers using a rubric to identify level of scientific understanding. Quantitative analyses included Rasch analysis used to normalize survey data. Independent samples t-tests were then employed to compare students' forced-choice responses to their written responses and to the confidence ratings, as well as to compare fourth and eighth grade students' responses. Findings indicated that eighth grade students generally outperformed the fourth grade on both the forced

Regeneration of the eighth cranial nerve in the bullfrog, Rana catesbeiana.

PubMed

Newman, A; Honrubia, V

1992-01-01

The present study was done in order to document the ability of the eighth cranial nerve of the bullfrog (Rana catesbeiana) to regenerate, the anatomic characteristics of the regenerated fibers, and the specificity of projections from individual endorgan branches of the nerve. The eighth cranial nerve was sharply transected between the ganglion cells and the brain stem in 40 healthy bullfrogs and allowed to regenerate. Anatomic studies were performed in these animals a minimum of 3 months postoperatively. Horseradish peroxidase was used to label the whole vestibular nerve or its individual endorgan branches. Labeled regenerated fibers could be identified crossing the site of the nerve section and projecting centrally to the vestibular nuclei in a pattern similar to that of normal frogs. Labeling of individual branches showed that regenerated fibers innervated the same specific areas found in normal frogs. Unlike normal animals, both thick and thin fibers projected to the medial nucleus.

2015-12-01

The International Psycho-oncology Society (IPOS) has just celebrated its 30th anniversary. The growth of psychosocial oncology has been exponential, and this relatively new field is becoming a core service that focuses on prevention, reducing the burden of cancer, and enhancing the quality of life from time of diagnosis, through treatment, survivorship, and palliative care. Looking back over the past 30 years, we see that cancer care globally has evolved to a new and higher standard. Today, 'cancer care for the whole patient' is being accomplished with an evidence-based model that addresses psychosocial needs and integrates psycho-oncology into the treatment and care of patients. The President's Plenary Session in Lisbon, Portugal, highlighted the IPOS Mission of promoting global excellence in psychosocial care of people affected by cancer through our research, public policy, advocacy, and education. The internationally endorsed IPOS Standard of Quality Cancer Care, for example, clearly states the necessity of integrating the psychosocial domain into routine care, and that distress should be measured as the sixth vital sign after temperature, blood pressure, pulse, respiratory rate, and pain. The plenary paper also discussed the global progress being made in Europe, North America, and Australia in providing quality cancer care for the whole patient. Collaborative partnerships between IPOS and organizations such as the European Partnership Action Against Cancer and the World Health Organization are essential in building capacity for the delivery of high-quality psycho-oncology services in the future.

2014-01-01

Following the highly successful inaugural meeting in 2012, the second installment of Virus-Like Particles and Nano-Particle Vaccines (VLPNPV), proved to be a worthy follow-up in an outstanding conference series. VLPNPV is a forum for academics and industry to address one of the major areas of need in biomedical sciences, the development of novel prophylactic and therapeutic vaccines. The conference was opened by Professor Marianne Manchester of the University of California, San Diego who pointed to the significance of the site chosen for the conference, the Salk Institute. Founded by Jonas Salk, the Salk Institute for Biological Studies is a non-profit, independent research institute with focuses in molecular biology and genetics, neurosciences, and plant biology. This diversity in research themes reflects the wishes of the institute's founder who saw value in using interdisciplinary approaches to understanding the basic principles in life, aimed at generating new therapies and treatments for human disease. Likewise, interdisciplinarity was reflected in the main themes of the meeting, which also highlight some of the potential advantages of virus-like particle (VLP) and nanoparticle vaccines, including novel formulations/adjuvanting effects, structurally accurate/designed antigens, production systems and capacity, and tailoring the immune response. These themes were covered by the 2 plenary sessions that opened the conference and are described in this report.

Quasi Eighth-Mode Substrate Integrated Waveguide (SIW) Fractal Resonator Filter Utilizing Gap Coupling Compensation

NASA Astrophysics Data System (ADS)

Zhang, Sheng; Rao, Jia-Yu; Tai, Wen-Si; Wang, Ting; Liu, Fa-Lin

2016-09-01

In this paper, a kind of quasi eighth substrate integrated waveguide resonator (QESIWR) with defected fractal structure (DFS) is proposed firstly. Compared with the eighth substrate integrated waveguide resonator (ESIWR), this kind of resonator has lower resonant frequency (f0), acceptable unloaded quality (Qu) value and almost unchanged electric field distribution. In order to validate the properties of QESIWR, a cascaded quadruplet QESIWRs filter is designed and optimized. By using cross coupling and gap coupling compensation, this filter has two transmission zeros (TZs) at each side of the passband. Meanwhile, in comparison with the conventional ones, its size is cut down over 90 %. The measured results agree well with the simulated ones.

"TAARgeting Addiction"--The Alamo Bears Witness to Another Revolution: An Overview of the Plenary Symposium of the 2015 Behavior, Biology and Chemistry Conference.

PubMed

Grandy, David K; Miller, Gregory M; Li, Jun-Xu

2016-02-01

In keeping with the free-thinking tradition San Antonians are known for, the Scientific Program Committee of the Behavior, Biology and Chemistry: Translational Research in Addiction Conference chose trace amine-associated receptor 1 (TAAR1) as the focus of the plenary symposium for its 7th annual meeting held at the University of Texas Health Science Center at San Antonio on March 14 and 15, 2015. The timing of the meeting's plenary session on TAAR1 coincided with the Ides of March, an apt concurrence given the long association of this date with the overthrow of the status quo. And whether aware of the coincidence or not, those in attendance witnessed the plunging of the metaphorical dagger into the heart of the dopamine (DA) transporter (DAT)-centric view of psychostimulant action. The symposium's four plenary presentations focused on the molecular and cellular biology, genetics, medicinal chemistry and behavioral pharmacology of the TAAR1 system and the experimental use of newly developed selective TAAR1 ligands. The consensus was that TAAR1 is a DA and methamphetamine receptor, interacts with DAT and DA D2 receptors, and is essential in modulating addiction-related effects of psychostimulants. Collectively the findings presented during the symposium constitute a significant challenge to the current view that psychostimulants such as methamphetamine and amphetamine solely target DAT to interfere with normal DA signaling and provide a novel conceptual framework from which a more complete understanding of the molecular mechanisms underlying the actions of DA and METH is likely to emerge.

Ramowski, Sarah K; Nystrom, Robert J; Rosenberg, Kenneth D; Gilchrist, Julie; Chaumeton, Nigel R

2012-05-01

To examine the risk behaviors associated with participation in the "choking game" by eighth-graders in Oregon. We obtained data from the 2009 Oregon Healthy Teens survey, a cross-sectional weighted survey of 5348 eighth-graders that questioned lifetime prevalence and frequency of choking game participation. The survey also included questions about physical and mental health, gambling, sexual activity, nutrition, physical activity/body image, exposure to violence, and substance use. Lifetime prevalence of choking game participation was 6.1% for Oregon eighth-graders, with no differences between males and females. Of the eighth-grade choking game participants, 64% had engaged in the activity more than once and 26.6% >5 times. Among males, black youth were more likely to participate than white youth. Among both females and males, Pacific Islander youth were much more likely to participate than white youth. Multivariate logistic regression revealed that sexual activity and substance use were significantly associated with choking game participation for both males and females. At >6%, the prevalence of choking game participation among Oregon youth is consistent with previous findings. However, we found that most of those who participate will put themselves at risk more than once. Participants also have other associated health risk behaviors. The comprehensive adolescent well visit, as recommended by the American Academy of Pediatrics, is a good opportunity for providers to conduct a health behavior risk assessment and, if appropriate, discuss the dangers of engaging in this activity.

The effects of school policies and practices on eighth-grade science achievement: A multilevel analysis of TIMSS

NASA Astrophysics Data System (ADS)

Smyth, Carol Ann Mary

Identifying the relative importance of both alterable school policies and fairly stable contextual factors as they relate to middle level science achievement, a domain of identified national concern, requires simultaneous investigation of multilevel predictors (i.e., student level and school level) specific to the grade level and academic subject area. The school level factors are predictors associated with both the school (e.g., average socioeconomic status, tracking, and instructional time) and the classroom (e.g., average academic press of peers, teacher collaboration, and instructional strategies). The current study assessed the effects of school policies, practices, and contextual factors on the science achievement of eighth grade students. These influences were considered to be both additive (i.e., influencing the mean achievement in a school after controlling for student characteristics) and interactive (i.e., affecting the relationships between student background characteristics and individual achievement). To account for the nested structure of predictors and cross level interactions among predictors, a multilevel model for middle level science achievement was estimated using hierarchical linear modeling (HLM) with data collected from eighth grade students, science teachers, and administrators in 1995 as part of the Third International Mathematics and Science Study (TIMSS). The major findings of this research suggest that although average eighth grade science achievement in a school was primarily associated with the contextual characteristics of the classroom and the school (e.g., average socioeconomic status and average academic press), both the academic differentiating influence of prior achievement and the social differentiating influence of parental education on the science achievement of eighth grade students were related not only to contextual characteristics of the classroom and the school, but also to the instructional policies of the classroom

2010-02-15

The purpose of this paper is to describe a unique 'eighth note' deformity of the autogenous radiocephalic fistula for hemodialysis and to retrospectively evaluate the efficacy and safety of its endovascular treatment. Over 3 years, a total of 808 patients and 558 autogenous radiocephalic fistulas were treated for vascular access dysfunction or thrombosis. These included 14 fistulas in 14 patients (9 men, 5 women; mean age, 58.2 {+-} 2.8 years; range 27-79 years) whose fistulograms before treatment resembled a musical note, the eighth note. Endovascular treatment sought to remodel the deformed vascular access to a classic radiocephalic fistula and increasemore » the number of cannulation sites available for hemodialysis. The technical and clinical success rates were each 92.8% (13/14). Fistula remodeling was successful in 13 patients. The postintervention primary patency was 100% at 90 days, 91.7 {+-} 0.8% at 120 days, 78.6 {+-} 13.9% at 180 days, 62.9 {+-} 17.9% at 360 days, 31.4 {+-} 24.0% at 540 days, and 0% at 720 days. The postintervention secondary patency was 100% at 90 days, 100% at 120 days, 100% at 180 days, 85.7 {+-} 13.2% at 360 days, and 85.7 {+-} 13.2% at 720 days. No major complications were noted. Minor complications were found in 71.4% of patients, all of which resolved spontaneously. In conclusion, endovascular treatment of fistulas with the eighth note deformity can effectively increase the number of available cannulation sites, facilitate fistula maturation, and facilitate thromboaspiration after fistula thrombosis.« less

Webber, Larry S.; Elder, John P.; Ward, Dianne; Evenson, Kelly R.; Dowda, Marsha; Chae, Soo Eun; Treuth, Margarita S.

2012-01-01

Purpose To examine “travel by walking” (TBW) before and after school among eighth grade girls. Methods Participants attended 36 middle schools from Arizona, Maryland, Minnesota, New Orleans, California and South Carolina participating in the Trial of Activity for Adolescent Girls (TAAG). The cross-sectional sample consisted of 3,076 eighth grade girls, and the longitudinal sample included 1,017 girls who participated in both 6th and 8th grades. Travel by walking before or after school status was determined from the 3-Day Physical Activity Recall (3DPAR). The main outcomes were body mass index (BMI) and physical activity, which was measured by accelerometry, estimated for total physical activity (light, moderate, vigorous) and moderate to vigorous physical activity (MVPA). Results Eighth grade girls who reported TBW had 4 more minutes (95% confidence interval ([CI], 2.1–6.1.) of MVPA before and after school than non-walkers, and 2 more minutes of MVPA (95% CI, 1.1–3.1) on an average weekday. In the longitudinal sample, girls who reported TBW before and after school in both 6th and 8th grades (consistent walkers) accumulated more minutes of MVPA for an average weekday than inconsistent walkers in both sixth (27 min.±2.2 vs. 25 min.±1.9; p=.03) and eighth grades (28 min.±2.6 vs. 25 min.±2.3; p=.003). There were no differences in BMI by walking status. Conclusions Adolescent girls who reported TBW before and after school accumulated more minutes of MVPA than non-walkers. Efforts to prevent the decline in walking to school in middle school girls could contribute to their overall physical activity. PMID:23174472

Hines, Jonas Z; Fiala, Steven C; Hedberg, Katrina

2017-06-16

During 2011-2015, increased electronic cigarette (e-cigarette) and hookah use offset declines in cigarette and other tobacco product use among youths (persons aged <18 years) (1). Limited information exists about which tobacco product introduced youths to tobacco product use. Patterns of first use of e-cigarettes among Oregon youths who were tobacco users were assessed in the Oregon Healthy Teens 2015 survey, a cross-sectional survey of eighth and 11th grade students in Oregon. Respondents were asked, "The very first time you used any tobacco or vaping product, which type of product did you use?" Among students who had ever used any tobacco product (ever users), e-cigarettes were the most common introductory tobacco product reported by both eighth (43.5%) and 11th (34.4%) grade students. Among students who used a tobacco product for ≥1 day during the past 30 days (current users), e-cigarettes were the most common introductory tobacco product reported by eighth grade students (44.4%) and the second most common introductory tobacco product reported by 11th grade students (31.0%). Introductory use of e-cigarettes was commonly reported among youths in Oregon who were ever or current tobacco users, underscoring the importance of proven interventions to prevent all forms of tobacco use among youths (2,3).

Digital science games' impact on sixth and eighth graders' perceptions of science

NASA Astrophysics Data System (ADS)

Peng, Li-Wei

2009-12-01

The quasi-experimental study investigated sixth and eighth graders' perceptions of science with gender, grade levels, and educational experiences as the variables. The Theory of Planned Behavior (Ajzen, 1985) claims that attitude toward the behavior, subjective norm, and perceived behavioral control play a major role in people's intentions, and these intentions ultimately impact their behavior. The study adopted a quantitative research approach by conducting a science perceptions survey for examining students' self-efficacy in learning science (i.e., perceived behavioral control), value of science (i.e., attitude toward the behavior), motivation in science (i.e., attitude toward the behavior), and perceptions of digital science games in science classes (i.e., perceived behavioral control). A total of 255 participants' responses from four rural Appalachian middle school science classrooms in southeastern Ohio were analyzed through a three-way ANCOVA factorial pre-test and post-test data analysis with experimental and comparison groups. Additionally, the study applied a semi-structured, in-depth interview as a qualitative research approach to further examine STEAM digital science games' and Fellows' impact on students' perceptions of science. Eight students in the experimental group were interviewed. Interview data were analyzed with an inductive method. The results found in the three-way ANCOVA data analysis indicated that the diversity of educational experiences was a significant factor that impacted sixth and eighth graders' perceptions of science. Additionally, the interaction of gender and educational experiences was another significant factor that impacted sixth and eighth graders' perceptions of science. The findings of the two short-answer questions identified the reasons why the participants liked or disliked science, as well as why the participants would or would not choose a career in science. The conclusions of the semi-structured, in-depth interview

The quality of abstracts presented at a conference reflects the academic activity and research productivity of the surgical/scientific association concerned. The abstract to publication rate (44.5 % internationally), is an important indicator of the quality of presented research. To evaluate the publication rate and impact of abstracts presented at the plenary session of the Sir Peter Freyer Surgical Symposium over a 25-year period (1989-2014), and identify factors influencing publication. Plenary abstracts were identified from abstract books of the Symposium from 1989-2014. The authors, institution, subspecialty and research subject were recorded. A Medline search with name of the first and last author, key words and content of all abstracts was conducted to identify related publications. The impact factor (IF) of the journal and the time to publication was recorded. 298 presented abstracts resulted in 168 publications (publication rate: 56 %). Basic Science research accounted for 80 % (n = 237) of the total number of presentations with the remaining 20 % (n = 61) being categorised as clinical research. Overall, cancer research accounted for 48 % of presented work. The average time to publication was 2 ± 7 years, while 11 % of all published studies achieved publication in the year of the symposium. The median impact factor for published research was 3.558 (IF range 0-39). These results indicate that the quality of papers presented at the Sir Peter Freyer Surgical Symposium compares favourably with international equivalents, making this meeting an important forum for Irish Academic Surgery.

Highly ionizing atomic nuclei HZE in the GCR will be a significant source of radiation exposure for humans on extended missions outside low Earth orbit. Accelerators such as the LBNL Bevalac and the BNL AGS, designed decades ago for fundamental nuclear and particle physics research, subsequently found use as sources of GCR-like particles for ground-based physics and biology research relevant to space flight. The NASA Space Radiation Laboratory at BNL was constructed specifically for space radiation research. Here we review some of the space-related physics results obtained over the first 20 years of NASA-sponsored research at Brookhaven. Copyright © 2016 The Committee on Space Research (COSPAR).

Genetic concepts in Greek literature from the eighth to the fourth century B.C.

PubMed

Bazopoulou-Kyrkanidou, E

1992-03-01

A review of the concepts of genetics found in epic, historical and dramatic ancient Greek writings from the eighth to the fourth centuries B.C., is presented. The derived data suggest that the development of genetical concepts and ideas started with the praise of the heroes' divine or noble origin in Homer's epic poems (eighth century B.C.). It continued in the tracing of the descent and vicissitudes of the families of the Greek gods and the common ancestry of the Greek tribes as described in Hesiod's genealogical poems (around 700 B.C.), in the statement of descent and dual parenthood of leaders and kings in the books of Herodotus and Xenophon (fifth and fourth centuries B.C.), and in the concern about the lineage of the tragic figures in Greek drama (fifth century B.C.). The genetical concepts expressed in these writings most probably reflected popular notions of that time. They must, therefore, have been the basis of the perceptions and theories on heredity and procreation expressed by the ancient physicians and philosophers in the fifth and fourth centuries B.C., which in turn influenced the development of genetics for many centuries.

Controversy in the classroom: How eighth-grade and undergraduate students reason about tradeoffs of genetically modified food

NASA Astrophysics Data System (ADS)

Seethaler, Sherry Lynn

Current issues in science provide a rich context for learning because they can involve complex tradeoffs that cut across traditional disciplinary boundaries. Despite this potential benefit, and the need for citizens to make decisions about such issues, science controversy remains rare in the classroom. Consequently, there is much unknown about how students make sense of complex, multidisciplinary science. This research examined eighth-grade (n = 190) and undergraduate (n = 9) students' reasoning about tradeoffs in the genetically modified food controversy (main study). To extend the findings from the main study, undergraduate students' reasoning was followed as they learned about ten additional science controversies (extension). The studies took place in the context of curricula designed on the basis of the Scaffolded Knowledge Integration Framework, which posits a set of design principles that help students form a rich, integrated network of ideas about a topic. Two new methodologies were developed for this work. The Embedded Perspective of Science Controversy was used to study students' integration of content in their written arguments (main study) and oral and written questions (extension). The Perspective views science controversy as a set of nested levels, where tradeoffs are one of the levels, but connecting to other levels (underlying scientific details, bigger picture context, etc.) is important for the weighing of tradeoffs. A scheme based on Toulmin's (1958) work on argumentation provided a way of comparing the structure of students' arguments. As indicated by pre and post test scores, the curriculum helped both eighth-grade students (t = 11.7, p < 0.0001) and undergraduates (t = 13.9, p < 0.0001) learn about genetically modified food. In their final papers, both eighth-grade and undergraduate students presented evidence for and against their positions, in contrast with prior literature showing individuals have difficulty coming up with evidence against

OBJECTIVE Malignant peripheral nerve sheath tumors (MPNSTs) of the eighth cranial nerve (CN) are exceedingly rare. To date the literature has focused on MPNSTs occurring after radiation therapy for presumed benign vestibular schwannomas (VSs), while MPNSTs arising without prior irradiation have received little attention. The objectives of the current study are to characterize the epidemiology, clinical presentation, disease course, and outcome using a large national cancer registry database and a systematic review of the English literature. Additionally, a previously unreported case is presented. METHODS The authors conducted an analysis of the Surveillance, Epidemiology, and End Results (SEER) database, a systematic review of the literature, and present a case report. Data from all patients identified in the SEER database with a diagnosis of MPNST involving the eighth CN, without a history of prior radiation, were analyzed. Additionally, all cases reported in the English literature between January 1980 and March 2015 were reviewed. Finally, 1 previously unreported case is presented. RESULTS The SEER registries identified 30 cases between 1992 and 2012. The average incidence was 0.017 per 1 million persons per year (range 0.000-0.0687 per year). The median age at diagnosis was 55 years, and 16 (53%) were women. Thirteen cases were diagnosed upon autopsy. Of the 17 cases diagnosed while alive, the median follow-up was 118 days, with 3 deaths (18%) observed. When compared with the incidence of benign VS, 1041 VSs present for every 1 MPNST arising from the eighth CN. Including a previously unreported case from the authors' center, a systematic review of the English literature yielded 24 reports. The median age at diagnosis was 44 years, 50% were women, and the median tumor size at diagnosis was 3 cm. Eleven patients (46%) reported isolated audiovestibular complaints typical for VS while 13 (54%) exhibited facial paresis or other signs of a more aggressive process

The study was conducted in 12 middle schools to determine the prevalence of diabetes, pre-diabetes, and diabetes risk factors in eighth-grade students who were predominantly minority and evaluate the feasibility of collecting physical and laboratory data in schools. Anthropometric measurements and fasting and 2-h post-glucose load blood draws were obtained from approximately 1,740 eighth-grade students. Mean recruitment rate was 50% per school, 49% had BMI > or = 85th percentile, 40.5% had fasting glucose > or = 100 mg/dl, 0.4% had fasting glucose > or = 126 mg/dl, and 2.0% had 2-h glucose > or = 140 mg/dl and 0.1% > or = 200 mg/dl. Mean fasting insulin value was 30.1 microU/ml, 36.2% had fasting insulin > or = 30 microU/ml, and 2-h mean insulin was 102.1 microU/ml. Fasting and 2-h glucose and insulin values increased across BMI percentiles, and fasting glucose was highest in Hispanic and Native American students. There was a high prevalence of risk factors for diabetes, including impaired fasting glucose (> or =100 mg/dl), hyperinsulinism suggestive of insulin resistance (fasting insulin > or = 30 microU/ml), and BMI > or = 85th percentile. These data suggest that middle schools are appropriate targets for population-based efforts to decrease overweight and diabetes risk.

"Beyond the walls": A research study of eighth-grade students mentored in a hospital setting

NASA Astrophysics Data System (ADS)

Grattan, Aileen

This research study was designed to evaluate twelve eighth-grade students participating in the fourth year of a mentoring program to determine what effect the mentoring experience would have on the students' sense of a scientific community, their understanding of scientific knowledge and process skills and attitudes toward science. The mentoring program was developed through a partnership established between the researcher, an eighth-grade science teacher at a junior high school, and an administrator of a local hospital, to provide educational opportunities for students mentored by medical professionals. The research design included qualitative and quantitative methods of analysis. The qualitative instruments were student journals and interviews. The quantitative instruments included the science subtest of the Stanford Nine Achievement Test, a Student Attitude Toward Science Survey (STATS), and a Hospital Questionnaire. The findings indicate that mentoring developed the students' understanding of a scientific community, revealed a wide range of attitudes and had a positive effect on the students' scientific knowledge and process skills. Finally, this research study has shown the benefits of mentoring as a model for teaching science in a community setting beyond the walls of the school.

2009-03-01

Regulation of receptor-type phosphatases can involve the formation of higher-order structures, but the exact role played in this process by protein domains is not well understood. In this study we show the formation of different higher-order structures of the receptor-type phosphatase PTPRJ, detected in HEK293A cells transfected with different PTPRJ expression constructs. In the plasma membrane PTPRJ forms dimers detectable by treatment with the cross-linking reagent BS(3) (bis[sulfosuccinimidyl]suberate). However, other PTPRJ complexes, dependent on the formation of disulfide bonds, are detected by treatment with the oxidant agent H(2)O(2) or by a mutation Asp872Cys, located in the eighth fibronectin type III domain of PTPRJ. A deletion in the eighth fibronectin domain of PTPRJ impairs its dimerization in the plasma membrane and increases the formation of PTPRJ complexes dependent on disulfide bonds that remain trapped in the cytoplasm. The deletion mutant maintains the catalytic activity but is unable to carry out inhibition of proliferation on HeLa cells, achieved by the wild type form, since it does not reach the plasma membrane. Therefore, the intact structure of the eighth fibronectin domain of PTPRJ is critical for its localization in plasma membrane and biological function.

Lin, Tzung-Jin; Goh, Amos Yoong Shin; Chai, Ching Sing; Tsai, Chin-Chung

2013-07-01

Background and purpose . Research in nature of science (NOS) among Asia-Pacific countries such as Singapore is arguably scarce. This study aimed to survey Singaporean secondary school students' views of NOS with a newly developed instrument named Students' Views of Nature of Science (SVNOS), which included various key aspects of NOS that are generally agreed upon by the science education community. Moreover, the relations between some demographic factors, including gender and grade, and students' views of NOS were explored. Sample, design and method In total, 359 Singaporean seventh and eighth graders were invited to participate in this survey. The reliability, validity and structure of the SVNOS instrument were ensured by confirmatory factor analysis. A two-way multivariate analysis of variance was then conducted to determine the interaction effects between the gender variable and the grade-level variable. Results and conclusion The results indicated that the SVNOS instrument is reliable and valid to assess students' views of NOS regarding seven distinct NOS dimensions. The male students were more prone to have constructivist-oriented views of NOS in the most of the SVNOS dimensions, while the female students conveyed more non-objective views of NOS. In addition, the eighth graders revealed more empiricist-oriented views of NOS than the seventh graders in several SVNOS dimensions. This result seems to contradict the results of previous studies that students' views of NOS may reflect a developmental trend with their increasing educational experiences.

NASA Astrophysics Data System (ADS)

Williams, Tammy Kay

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.

Apollo and the geology of the moon /Twenty-eighth William Smith Lecture/

NASA Technical Reports Server (NTRS)

Schmitt, H. H.

1975-01-01

Lunar geology evidence is examined for clues to the origin and evolution of the moon and earth. Seven evolutionary episodes, the last covering three billion years to the present day, are constructed for the moon. Parallel episodes in the earth's evolution are masked by the dynamic continuing evolution of the earth over a 4.5 billion year span, in contrast to the moon's quiescence and inability to retain fluids. Comparisons are drawn between the geochemistry and tectonics of the lunar basaltic maria and the earth's ocean basins. Lunar maria rocks differ strikingly in chemical composition from meteoritic matter and solar material. Inundation of frontside lunar maria basins by vast oceans of dark basalt mark the last of the major internally generated evolutionary episodes, and is attributed to consequences of meltdown of the lunar mantle and crust by radioisotope decay from below. Data are drawn primarily from Apollo missions 11-17, supplemented by other sources.

Predicting weight status stability and change from fifth grade to eighth grade: the significant role of adolescents' social-emotional well-being.

PubMed

Chang, Yiting; Gable, Sara

2013-04-01

The primary objective of this study was to predict weight status stability and change across the transition to adolescence using parent reports of child and household routines and teacher and child self-reports of social-emotional development. Data were from the Early Childhood Longitudinal Study-Kindergarten Cohort (ECLS-K), a nationally representative sample of children who entered kindergarten during 1998-1999 and were followed through eighth grade. At fifth grade, parents reported on child and household routines and the study child and his/her primary classroom teacher reported on the child's social-emotional functioning. At fifth and eighth grade, children were directly weighed and measured at school. Nine mutually-exclusive weight trajectory groups were created to capture stability or change in weight status from fifth to eighth grade: (1) stable obese (ObeSta); (2) obese to overweight (ObePos1); (3) obese to healthy (ObePos2); (4) stable overweight (OverSta); (5) overweight to healthy (OverPos); (6) overweight to obese (OverNeg); (7) stable healthy (HelSta); (8) healthy to overweight (HelNeg1); and (9) healthy to obese (HelNeg2). Except for breakfast consumption at home, school-provided lunches, nighttime sleep duration, household and child routines did not predict stability or change in weight status. Instead, weight status trajectory across the transition to adolescence was significantly predicted by measures of social-emotional functioning at fifth grade. Assessing children's social-emotional well-being in addition to their lifestyle routines during the transition to adolescence is a noteworthy direction for adolescent obesity prevention and intervention.

A Mixed-Methods Study on the Impact of Socratic Seminars on Eighth Grade Students' Comprehension of Science Texts

NASA Astrophysics Data System (ADS)

Roncke, Nancy

This formative, convergent-mixed methods research study investigated the impact of Socratic Seminars on eighth grade science students' independent comprehension of science texts. The study also highlighted how eighth grade students of varying reading abilities interacted with and comprehended science texts differently during and after the use of Socratic Seminars. In order to document any changes in the students' overall comprehension of science texts, this study compared the experimental and control groups' pre- and post-test performances on the Content Area Reading Assessment (Leslie & Caldwell, 2014) and self-perception surveys on students' scientific reading engagement. Student think-alouds and interviews also captured the students' evolving understandings of the science texts. At the conclusion of this sixteen-week study, the achievement gap between the experimental and control group was closed in five of the seven categories on the Content Area Reading Assessment, including supporting an inference with textual evidence, determining central ideas, explaining why or how, determining word meaning, and summarizing a science text. Students' self-perception surveys were more positive regarding reading science texts after the Socratic Seminars. Finally, the student think-alouds revealed that some students moved from a literal interpretation of the science texts to inquiries that questioned the text and world events.

A backward dark-optical-comb-injection mode-locked semiconductor optical amplifier fiber laser (SOAFL) with a femtosecond pulse width and an ultrahigh supermode-noise suppressing ratio (SMSR) is primarily demonstrated. The mode-locked SOAFL pulse with a spectral linewidth of 0.45 nm is shortened from 15 to 8.6 ps under chirp compensation in a 420 m long dispersion-compensated fiber, corresponding to a time-bandwidth product of 0.48. The eighth-order soliton is obtained by the nonlinearly soliton's compression of the chirp-compensated SOAFL pulse in a 112 m long single-mode fiber at an input peak power of 51 W, providing the pulse width, the linewidth, and the nearly transform-limited time-bandwidth product are <200 fs, 13.8 nm, and 0.34, respectively. The phase noise and integrated timing jitter at an offset frequency below 1 MHz are -105 dBc/Hz and 0.8 ps, respectively. An ultrahigh pulse-compression ratio of 43 and a SMSR of 87 dB for the eighth-order SOAFL soliton are reported.

Cancer of the Esophagus and Esophagogastric Junction: An Eighth Edition Staging Primer

Rice, Thomas W.; Ishwaran, Hemant; Ferguson, Mark K.; Blackstone, Eugene H.; Goldstraw, Peter

2017-01-01

This primer for eighth edition staging of esophageal and esophagogastric epithelial cancers presents separate classifications for the clinical (cTNM), pathologic (pTNM), and postneoadjuvant pathologic (ypTNM) stage groups, which are no longer shared. For pTNM, pT1 has been subcategorized as pT1a and pT1b for the subgrouping pStage I adenocarcinoma and squamous cell carcinoma. A new, simplified esophagus-specific regional lymph node map has been introduced. Undifferentiated histologic grade (G4) has been eliminated; additional analysis is required to expose histopathologic cell type. Location has been removed as a category for pT2N0M0 squamous cell cancer. The definition of the esophagogastric junction has been revised. ypTNM stage groups are identical for both histopathologic cell types, unlike those for cTNM and pTNM. PMID:27810391

Cakan, Mehtap

2003-10-01

The Group Embedded Figures Test was administered to 206 Turkish (123 boys versus 83 girls) eighth grade students. Distribution characteristics, item analysis, reliability, and internal consistency are presented. No sex differences on subsections or the full scale were found. Socioeconomic status as indicated by parental education was significantly associated with the cognitive style scores of the students. Subjects whose fathers had a higher education outperformed those whose fathers had less education. No significant differences in students' means were found among groups whose mothers had low, middle, and high education. The Turkish sample showed the same performance as a 5th grade American sample, and Canadian 8th graders outperformed the Turkish participants. The practice effects are also discussed.

A Cross-Cultural Comparison of Singaporean and Taiwanese Eighth Graders' Science Learning Self-Efficacy from a Multi-Dimensional Perspective

NASA Astrophysics Data System (ADS)

Lin, Tzung-Jin; Tan, Aik Ling; Tsai, Chin-Chung

2013-05-01

Due to the scarcity of cross-cultural comparative studies in exploring students' self-efficacy in science learning, this study attempted to develop a multi-dimensional science learning self-efficacy (SLSE) instrument to measure 316 Singaporean and 303 Taiwanese eighth graders' SLSE and further to examine the differences between the two student groups. Moreover, within-culture comparisons were made in terms of gender. The results showed that, first, the SLSE instrument was valid and reliable for measuring the Singaporean and Taiwanese students' SLSE. Second, through a two-way multivariate analysis of variance analysis (nationality by gender), the main result indicated that the SLSE held by the Singaporean eighth graders was significantly higher than that of their Taiwanese counterparts in all dimensions, including 'conceptual understanding and higher-order cognitive skills', 'practical work (PW)', 'everyday application', and 'science communication'. In addition, the within-culture gender comparisons indicated that the male Singaporean students tended to possess higher SLSE than the female students did in all SLSE dimensions except for the 'PW' dimension. However, no gender differences were found in the Taiwanese sample. The findings unraveled in this study were interpreted from a socio-cultural perspective in terms of the curriculum differences, societal expectations of science education, and educational policies in Singapore and Taiwan.

Artificial Intelligence and NASA Data Used to Discover Eighth Planet Circling Distant Star

NASA Image and Video Library

2017-12-12

Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light years from Earth. The planet was discovered in data from NASA’s Kepler space telescope. The newly-discovered Kepler-90i -- a sizzling hot, rocky planet that orbits its star once every 14.4 days -- was found by researchers from Google and The University of Texas at Austin using machine learning. Machine learning is an approach to artificial intelligence in which computers “learn.” In this case, computers learned to identify planets by finding in Kepler data instances where the telescope recorded signals from planets beyond our solar system, known as exoplanets.

2017-01-01

Chorea-Acanthocytosis (ChAc) is a rare hereditary neurological disorder characterized by abnormal movements, red blood cell pathology, and progressive neurodegeneration. Little is understood of the pathogenesis of ChAc and related disorders (collectively Neuroacanthocytosis). The Eighth International Chorea-Acanthocytosis Symposium was held in May 2016 in Ann Arbor, MI, USA, and focused on molecular mechanisms driving ChAc pathophysiology. Accompanying the meeting, members of the neuroacanthocytosis research community and other invited scientists met in a workshop to discuss the current understanding and next steps needed to better understand ChAc pathogenesis. These discussions identified several broad and critical needs for advancing ChAc research and patient care, and led to the definition of 18 specific action points related to functional and molecular studies, animal models, and clinical research. These action points, described below, represent tractable research goals to pursue for the next several years.

Twenty-eighth annual report of the Director of the United States Geological Survey

USGS Publications Warehouse

Smith, George Otis

1907-01-01

The plan of operations for the last fiscal year, including an itemized statement of the appropriations, amounting to $1,758,720, with the allotments thereof, was approved by the Secretary of the Interior on July 10, 1906. The work of the various branches and divisions conformed to this plan, and a detailed statement of their operations may be found on later pages. On January 23 the former Director, Charles D. Walcott, was appointed to the position of Secretary of the Smithsonian Institution, and his resignation as Director was accepted by the President, becoming effective April 30, 1907. Mr. Walcott has been a member of the Survey since its organization, and the thirteen years of his service as the administrative head of the bureau cover the period of its greatest growth. At the beginning of his directorship Mr. Walcott disclaimed any desire to make radical changes in either the policy or the administration of the Survey as developed under his predecessors, King and Powell, but in his first report, the Director's sixteenth, he mentioned certain readjustments which he deemed desirable in order that the Survey might better meet the economic and educational needs of the country. It is noteworthy that, almost without exception, these improvements have been accomplished, and even more fully than as then outlined. Among these changes may be mentioned : The raising of the standard of the topographic maps, with the representation thereon of land subdivision lines, and the extension of exact leveling and primary triangulation; the placing of the entire topographic and geologic force within the classified service; the obtaining of authority from Congress to issue separates of the annual report in pamphlet form, thus permitting advance publication of chapters of the Mineral Resources report, as well as of papers on economic geology; the enlargement of the work of the divisions of hydrography, mineral resources, and geology, in the last case providing for reconnaissance surveys of regions of economic importance. Equally notable was the growth of the Survey under Mr. Walcott's administration, as shown by the increase in both the extent and the scope of its operations. The appropriations for the last fiscal year amounted to more than four times the total of those made thirteen years ago, and there was, of course, a corresponding increase in the amount of field and office work performed. The development of the relations between the Geological Survey and the public within the same period is measured by a more than fourfold increase in amount of official correspondence, nearly fourfold increase in number of printed pages in the various reports of the year, and a more than fivefold increase in copies of maps printed, while the total annual distribution of publications, books, and maps grew from less than 200,000 to nearly a million copies, the sales increasing from $2,100 to over $18,000. The extent to which the results of the work by this organization are now utilized by both the industrial world and the educational and scientific institutions furnishes the best index of the degree of success attained by Mr. Walcott and his colleagues.

The recently published article "2014 Evidence-based guideline for the management of high blood pressure in adults: Report from the panel members appointed to the Eighth Joint National Committee (JNC 8)" (James et al., JAMA 311: 507-520, 2014) has generated considerable controversy. In this commentary, we evaluate the document and compare the recommendations contained within it with those of the JNC 7 and other national and international guidelines. The evidence quality rating approach followed by the article "2014 Evidence-based guideline for the management of high blood pressure in adults: Report from the panel members appointed to the Eighth Joint National Committee (JNC 8)" (James et al., JAMA 311: 507-520, 2014) disqualified nearly 98% of previous studies from review; as a result, some of the key recommendations were on the basis of expert opinion alone. We are especially concerned that the recommendation to raise the systolic/diastolic BP levels at which treatment is initiated to ≥150/≥90 mmHg in adults≥60 years old may affect cardiovascular and renal health in these patients. Additionally, we recommend that hypertension guidelines should be updated every 3-4 years with a fresh approach to the definition of target BP levels, the use of modern technology in the diagnosis of hypertension, and the treatment of hypertension in special populations not addressed in earlier guidelines.

Twenty-first century learning in afterschool.

PubMed

Schwarz, Eric; Stolow, David

2006-01-01

Twenty-first century skills increasingly represent the ticket to the middle class. Yet, the authors argue, in-school learning is simply not enough to help students develop these skills. The authors make the case that after-school (or out-of-school) learning programs are emerging as one of the nation's most promising strategies for preparing young people for the workforce and civic life. Most school systems have significant limitations for teaching twenty-first century skills. They have the limits of time: with only six hours per day there is barely enough time to teach even the basic skills, especially for those students starting already behind. They have the limits of structure: typical school buildings and classrooms are not physically set up for innovative learning. They have the limits of inertia and bureaucracy: school systems are notoriously resistant to change. And perhaps most important, they have the limits of priorities: especially with the onset of the No Child Left Behind Act, schools are laserlike in their focus on teaching the basics and therefore have less incentive to incorporate twenty-first century skills. Meanwhile, the authors argue that after-school programs are an untapped resource with three competitive advantages. First, they enable students to work collaboratively in small groups, a setup on which the modern economy will increasingly rely. Second, they are well suited to project-based learning and the development of mastery. Third, they allow students to learn in the real-world contexts that make sense. Yet the after-school sector is fraught with challenges. It lacks focus-Is it child care, public safety, homework tutoring? And it lacks rigorous results. The authors argue that the teaching of twenty-first century skills should become the new organizing principle for afterschool that will propel the field forward and more effectively bridge in-school and out-of-school learning.

Gentile, Douglas A

2010-04-01

Advertisers are adept at changing our attitudes and purchasing behaviors, but we rarely notice the effects. This plenary talk at the eighth annual Midwest Rural Agricultural Safety and Health Forum, November 2009, focused on the psychology of advertising and how advertising is designed to work outside of our conscious awareness. Several psychological "tricks" are used to influence us, with the goal being to get us to change our behaviors but to think that it was our idea all along. These tricks include using emotional appeals and persuasion techniques that rely on biases in human problem solving. This power can be used for social marketing, the use of these techniques to promote social well-being, rather than simply for commercial purposes. Understanding how advertising works therefore allows us to use this power to effect positive changes in society.

LES of Temporally Evolving Mixing Layers by an Eighth-Order Filter Scheme

NASA Technical Reports Server (NTRS)

Hadjadj, A; Yee, H. C.; Sjogreen, B.

2011-01-01

An eighth-order filter method for a wide range of compressible flow speeds (H.C. Yee and B. Sjogreen, Proceedings of ICOSAHOM09, June 22-26, 2009, Trondheim, Norway) are employed for large eddy simulations (LES) of temporally evolving mixing layers (TML) for different convective Mach numbers (Mc) and Reynolds numbers. The high order filter method is designed for accurate and efficient simulations of shock-free compressible turbulence, turbulence with shocklets and turbulence with strong shocks with minimum tuning of scheme parameters. The value of Mc considered is for the TML range from the quasi-incompressible regime to the highly compressible supersonic regime. The three main characteristics of compressible TML (the self similarity property, compressibility effects and the presence of large-scale structure with shocklets for high Mc) are considered for the LES study. The LES results using the same scheme parameters for all studied cases agree well with experimental results of Barone et al. (2006), and published direct numerical simulations (DNS) work of Rogers & Moser (1994) and Pantano & Sarkar (2002).

2015-10-01

Using a quasi-experimental, nonequivalent pretest/posttest control group design, the researchers examined the effects of online collaborative learning on eighth-grade student's sense of community in a physical science class. For a 9-week period, students in the control group participated in collaborative activities in a face-to-face learning environment, whereas students in the experimental group participated in online collaborative activities using the Edmodo educational platform in a hybrid learning environment. Students completed the Classroom Community Scale survey as a pretest and posttest. Results indicated that the students who participated in the face-to-face classroom had higher overall sense of community and learning community than students who participated in collaborative activities in the online environment. Results and implications are discussed and suggestions for future research are provided.

The aim of this study was to validate the new eighth edition of the TNM classification and to elucidate whether radiological solid size corresponds to pathological invasive size incorporated in this T factor. We analyzed the data on 1792 patients who underwent complete resection from 2003 to 2011 at the National Cancer Center Hospital East, Japan. We reevaluated preoperative thin-section computed tomography (TSCT) to determine solid size and pathological invasive size using the fourth edition of the WHO classification and reclassified them according to the new TNM classification. The discriminative power of survival curves by the seventh edition was compared with that by the eighth edition by using concordance probability estimates and Akaike's information criteria calculated using a univariable Cox regression model. Pearson's correlation coefficient was calculated to elucidate the correlation between radiological solid size using TSCT and pathological invasive size. The overall survival curves in the eighth edition were well distinct at each clinical and pathological stage. The 5-year survival rates of patients with clinical and pathological stage 0 newly defined were both 100%. The concordance probability estimate and Akaike's information criterion values of the eighth edition were higher than those of the seventh edition in discriminatory power for overall survival. Solid size on TSCT scan and pathological invasive size showed a positive linear relationship, and Pearson's correlation coefficient was calculated as 0.83, which indicated strong correlation. This TNM classification will be feasible regarding patient survival, and radiological solid size correlates significantly with pathological invasive size as a new T factor.

Aware that constituent support is essential to any educational endeavor, the AOL Time Warner Foundation (now the Time Warner Foundation), in conjunction with two respected national research firms, measured Americans' attitudes toward the implementation of twenty-first century skills. The foundation's national research survey was intended to explore public perceptions of the need for changes in the educational system, in school and after school, with respect to the teaching of twenty-first century skills. The author summarizes the findings of the survey, which were released by the foundation in June 2003. One thousand adults were surveyed by telephone, including African Americans, Latinos, teachers, and business executives. In general, the survey found that Americans believe today's students need a "basics-plus" education, meaning communication, technology, and critical thinking skills in addition to the traditional basics of reading, writing, and math. In fact, 92 percent of respondents stated that students today need different skills from those of ten to twenty years ago. Also, after-school programs were found to be an appropriate vehicle to teach these skills. Furthermore, the survey explored how well the public perceives schools to be preparing youth for the workforce and postsecondary education, which twenty-first century skills are seen as being taught effectively, and the level of need for after-school and summer programs. The survey results provide conclusive evidence of national support for basics-plus education. Thus, a clear opportunity exists to build momentum for a new model of education for the twenty-first century.

An Overview of a Trajectory-Based Solution for En Route and Terminal Area Self-Spacing: Eighth Revision

NASA Technical Reports Server (NTRS)

Abbott, Terence S.; Swieringa, Kurt S.

2017-01-01

This paper presents an overview of the eighth revision to an algorithm specifically designed to support NASA's Airborne Precision Spacing concept. This paper supersedes the previous documentation and presents a modification to the algorithm referred to as the Airborne Spacing for Terminal Arrival Routes version 13 (ASTAR13). This airborne self-spacing concept contains both trajectory-based and state-based mechanisms for calculating the speeds required to achieve or maintain a precise spacing interval with another aircraft. The trajectory-based capability allows for spacing operations prior to the aircraft being on a common path. This algorithm was also designed specifically to support a standalone, non-integrated implementation in the spacing aircraft. This current revision to the algorithm supports the evolving industry standards relating to airborne self-spacing.

The International Psycho-Oncology Society (IPOS) Human Rights Task Force has been working since 2008 to raise awareness and support, for the relevance of psychosocial cancer care as a human rights issue. In 2014 the "Lisbon Declaration: Psychosocial Cancer Care as a Universal Human Right" was fully endorsed by IPOS. Subsequently, the IPOS Standard on Quality Cancer Care, endorsed by 75 cancer organizations worldwide, has been updated and now includes 3 core principles: Psychosocial cancer care should be recognised as a universal human right; Quality cancer care must integrate the psychosocial domain into routine care; Distress should be measured as the 6th vital sign. The President's plenary held at the 2015 World Congress of Psycho-Oncology in Washington DC was devoted to discussing psychosocial care as a human rights issue. Many challenges and opportunities are illustrated in different continents and contexts: from Africa where resources for basic cancer treatment are scarce and children and their parents face significant difficulties with hospital detention practices; to Europe where for many countries psychosocial care is still seen as a luxury; and the Middle East where Muslim women face stigma and a culture of silence over cancer. We further discuss how to move the Lisbon Declaration forward towards its implementation into clinical practice globally, using the successful example of the World Health Assembly resolution supporting palliative care as a human right which has achieved widespread approval, and identifying the vital role the IPOS Federation of National Psychoncology Societies plays worldwide to move this agenda forward.

The NASA Propagation Experimenters (NAPEX) meeting is convened each year to discuss studies supported by the NASA Propagation Program. Representatives from the satellite communications industry, academia and government who have an interest in space-ground radio wave propagation are invited to NAPEX meetings for discussions and exchange of information. The reports delivered at this meeting by program managers and investigators present recent activities and future plans. This forum provides an opportunity for peer discussion of work in progress, timely dissemination of propagation results, and close interaction with the satellite communications industry. NAPEX XXI took place in El Segundo, California on June 11-12, 1997 and consisted of three sessions. Session 1, entitled "ACTS Propagation Study Results & Outcome " covered the results of 20 station-years of Ka-band radio-wave propagation experiments. Session 11, 'Ka-band Propagation Studies and Models,' provided the latest developments in modeling, and analysis of experimental results about radio wave propagation phenomena for design of Ka-band satellite communications systems. Session 111, 'Propagation Research Topics,' covered a diverse range of propagation topics of interest to the space community, including overviews of handbooks and databases on radio wave propagation. The ACTS Propagation Studies miniworkshop was held on June 13, 1997 and consisted of a technical session in the morning and a plenary session in the afternoon. The morning session covered updates on the status of the ACTS Project & Propagation Program, engineering support for ACTS Propagation Terminals, and the Data Center.

Understanding Curriculum, Instruction and Assessment within Eighth Grade Science Classrooms for Special Needs Students

NASA Astrophysics Data System (ADS)

Riedell, Kate Elizabeth

The Individuals with Disabilities Education Act (IDEA, 2004) cemented the fact that students with disabilities must be placed in the least restrictive environment and be given the necessary supports to help them succeed (Lawrence-Brown, 2004). This provides significant challenges for general education teachers, especially in an era of standards based reform with the adoption of the Common Core State Standards (CCSSI, 2014) by most states, along with the Next Generation Science Standards (NGSS, 2013). While a variety of methods, strategies, and techniques are available to teachers, there is a dearth of literature that clearly investigates how teachers take into account the ability and motivation of students with special needs when planning and implementing curriculum, instruction, and assessment. Thus, this study sought to investigate this facet through the lens of differentiation, personalization, individualization and universal design for learning (UDL) (CAST, 2015), all of which are designed to meet the needs of diverse learners, including students with special needs. An embedded single-case study design (Yin, 2011) was used in this study with the case being differentiated and/or personalized curriculum, instruction and/or assessment, along with UDL for students with special needs, with each embedded unit of analysis being one eighth grade general education science teacher. Analyzing each sub-unit or case, along with a cross-case analysis, three eighth grade general education science teachers were observed over the course of two 10-day units of study in the fall and spring, as they collected artifacts and completed annotations within their electronic portfolios (ePortfolios). All three eighth grade general education science teachers collected ePortfolios as part of their participation in a larger study within California, "Measuring Next Generation Science Instruction Using Tablet-Based Teacher Portfolios," funded by the National Science Foundation.

The Group on Earth Observations (GEO) through 2025

NASA Astrophysics Data System (ADS)

Ryan, Barbara; Cripe, Douglas

Ministers from the Group on Earth Observations (GEO) Member governments, meeting in Geneva, Switzerland in January 2014, unanimously renewed the mandate of GEO through 2025. Through a Ministerial Declaration, they reconfirmed that GEO’s guiding principles of collaboration in leveraging national, regional and global investments and in developing and coordinating strategies to achieve full and open access to Earth observations data and information in order to support timely and knowledge-based decision-making - are catalysts for improving the quality of life of people around the world, advancing global sustainability, and preserving the planet and its biodiversity. GEO Ministers acknowledged and valued the contributions of GEO Member governments and invited all remaining Member States of the United Nations to consider joining GEO. The Ministers also encouraged all Members to strengthen national GEO arrangements, and - of particular interest to COSPAR - they highlighted the unique contributions of Participating Organizations. In this regard, ten more organizations saw their applications approved by Plenary and joined the ranks along with COSPAR to become a Participating Organization in GEO, bringing the current total to 77. Building on the efforts of a Post-2015 Working Group, in which COSPAR participated, Ministers provided additional guidance for GEO and the evolution of its Global Earth Observation System of System (GEOSS) through 2025. Five key areas of activities for the next decade include the following: 1.) Advocating for the value of Earth observations and the need to continue improving Earth observation worldwide; 2.) Urging the adoption and implementation of data sharing principles globally; 3.) Advancing the development of the GEOSS information system for the benefit of users; 4.) Developing a comprehensive interdisciplinary knowledge base defining and documenting observations needed for all disciplines and facilitate availability and accessibility of

Abstract Later‐life changes in brain tissue volumes—decreases in the volume of healthy grey and white matter and increases in the volume of white matter hyperintensities (WMH)—are strong candidates to explain some of the variation in ageing‐related cognitive decline. We assessed fluid intelligence, memory, processing speed, and brain volumes (from structural MRI) at mean age 73 years, and at mean age 76 in a narrow‐age sample of older individuals (n = 657 with brain volumetric data at the initial wave, n = 465 at follow‐up). We used latent variable modeling to extract error‐free cognitive levels and slopes. Initial levels of cognitive ability were predictive of subsequent brain tissue volume changes. Initial brain volumes were not predictive of subsequent cognitive changes. Brain volume changes, especially increases in WMH, were associated with declines in each of the cognitive abilities. All statistically significant results were modest in size (absolute r‐values ranged from 0.114 to 0.334). These results build a comprehensive picture of macrostructural brain volume changes and declines in important cognitive faculties during the eighth decade of life.

The principle of cooperation and life's origin and evolution

NASA Technical Reports Server (NTRS)

Oro, J.; Armangue, G.; Mar, A.

1986-01-01

In simple terms a living entity is a negentropic system that replicates, mutates and evoluves. A number of suggestions have been made, such as directed panspermia, atmospheric photosynthesis, genetic overtaking from inorganic processes, etc., as alternative models to the accepted Oparin-Haldane-Urey model of the origin of life on Earth. This has probably occurred because in spite of tremendous advances in the prebiotic synthesis of biochemical compounds, the fundamental problem of the appearance of the first life--a primordial replicating cell-ancestral to all other forms of extant life, has remained elusive. This is indeed a reflection on the different fundamental nature of the problem involved. Regardless of which were the fundamental processes which occurred on the primitive Earth, it has to end up with the fundamental characteristics of an ancestral protocell. The problem of the emergence of the first ancestral cell was one of synergistic macromolecular cooperation, as it has been discussed by authors recently (COSPAR XXV Plenary Meeting). An analogous situation must have occurred at the time of the appearance of the first eucaryotic organism. Procaryotic life appeared probably during the first 600 million years of Earth history when the Earth was sufficiently cool and continually bombarded (in the late accretion period) by comets and minor bodies of the solar system, when the sea had not yet acquired its present form.

Answer questions and earn CME/CNE New to the eighth edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual for epithelial cancers of the esophagus and esophagogastric junction are separate, temporally related cancer classifications: 1) before treatment decision (clinical); 2) after esophagectomy alone (pathologic); and 3) after preresection therapy followed by esophagectomy (postneoadjuvant pathologic). The addition of clinical and postneoadjuvant pathologic stage groupings was driven by a lack of correspondence of survival, and thus prognosis, between both clinical and postneoadjuvant pathologic cancer categories (facts about the cancer) and pathologic categories. This was revealed by a machine-learning analysis of 6-continent data from the Worldwide Esophageal Cancer Collaboration, with consensus of the AJCC Upper GI Expert Panel. Survival is markedly affected by histopathologic cell type (squamous cell carcinoma and adenocarcinoma) in clinically and pathologically staged patients, requiring separate stage grouping for each cell type. However, postneoadjuvant pathologic stage groups are identical. For the future, more refined and granular data are needed. This requires: 1) more accurate clinical staging; 2) innovative solutions to pathologic staging challenges in endoscopically resected cancers; 3) integration of genomics into staging; and 4) precision cancer care with targeted therapy. It is the responsibility of the oncology team to accurately determine and record registry data, which requires eliminating both common errors and those related to incompleteness and inconsistency. Despite the new complexity of eighth edition staging of cancers of the esophagus and esophagogastric junction, these key concepts and new directions will facilitate precision cancer care.

Knox, Allyson

2006-01-01

Microsoft is an innovative corporation demonstrating the kind and caliber of job skills needed in the twenty-first century. It demonstrates its commitment to twenty-first century skills by holding its employees accountable to a set of core competencies, enabling the company to run effectively. The author explores how Microsoft's core competencies parallel the Partnership for 21st Century Skills learning frameworks. Both require advanced problem-solving skills and a passion for technology, both expect individuals to be able to work in teams, both look for a love of learning, and both call for the self-confidence to honestly self-evaluate. Microsoft also works to cultivate twenty-first century skills among future workers, investing in education to help prepare young people for competitive futures. As the need for digital literacy has become imperative, technology companies have taken the lead in facilitating technology training by partnering with schools and communities. Microsoft is playing a direct role in preparing students for what lies ahead in their careers. To further twenty-first century skills, or core competencies, among the nation's youth, Microsoft has established Partners in Learning, a program that helps education organizations build partnerships that leverage technology to improve teaching and learning. One Partners in Learning grantee is Global Kids, a nonprofit organization that trains students to design online games focused on global social issues resonating with civic and global competencies. As Microsoft believes the challenges of competing in today's economy and teaching today's students are substantial but not insurmountable, such partnerships and investments demonstrate Microsoft's belief in and commitment to twenty-first century skills.

Previous research suggests that students' social skills and achievement are interrelated, and some findings support bi-directional effects between the two constructs. The purpose of this research study was to estimate the possible longitudinal and reciprocal effects of social skills and achievement for kindergarten through eighth grade students. Data from the Early Childhood Longitudinal Study program were analyzed; teachers' ratings of students' social skills and students' standardized math and reading achievement performance were collected 4 and 5 times, respectively. Latent variable structural equation modeling was used to test a panel model of reciprocal, longitudinal effects of social skills and achievement. The results suggest that the effects of students' social skills and achievement are bi-directional, but the effects of students' achievement on their later social skills are stronger than the effects of social skills on achievement. The significant effects of students' social skills on their later achievement are mostly indirect. These findings suggest that the future social skills of students who struggle academically may be of particular concern to educators, and intervention and prevention efforts aimed to address both social and achievement skills may help remediate the other skill in the future.

Lo, Celia C; Cheng, Tyrone C; Bohm, Maggie; Zhong, Hua

2018-02-01

This examination of minor and serious delinquency among eighth graders in a large southern Chinese city, Guangzhou, also compared groups of these students, observing differences between the delinquency of migrants and that of urban natives. Data used were originally collected for the study "Stuck in the City: Migration and Delinquency Among Migrant Adolescents in Guangzhou." The present study asked whether and how various sources of strain and social control factors explained students' delinquency, questioning how meaningfully migration status moderated several of the observed delinquency relationships. Of students in the sample, 741 reported being natives of Guangzhou, and 497 reported migrating to Guangzhou from a rural area. The study conceptualized internal migration as a strain factor leading to delinquency, but the analyses did not suggest direct association between internal migration and delinquency. Results generally supported Agnew's theory, and, what's more, they tended to confirm that migration status moderated juvenile delinquency.

Planetary protection issues for sample return missions.

DeVincenzi, D L; Klein, H P

1989-01-01

Sample return missions from a comet nucleus and the Mars surface are currently under study in the US, USSR, and by ESA. Guidance on Planetary Protection (PP) issues is needed by mission scientists and engineers for incorporation into various elements of mission design studies. Although COSPAR has promulgated international policy on PP for various classes of solar system exploration missions, the applicability of this policy to sample return missions, in particular, remains vague. In this paper, we propose a set of implementing procedures to maintain the scientific integrity of these samples. We also propose that these same procedures will automatically assure that COSPAR-derived PP guidelines are achieved. The recommendations discussed here are the first step toward development of official COSPAR implementation requirements for sample return missions.

Cognitive assessment in mathematics with the least squares distance method.

Ma, Lin; Çetin, Emre; Green, Kathy E

2012-01-01

This study investigated the validation of comprehensive cognitive attributes of an eighth-grade mathematics test using the least squares distance method and compared performance on attributes by gender and region. A sample of 5,000 students was randomly selected from the data of the 2005 Turkish national mathematics assessment of eighth-grade students. Twenty-five math items were assessed for presence or absence of 20 cognitive attributes (content, cognitive processes, and skill). Four attributes were found to be misspecified or nonpredictive. However, results demonstrated the validity of cognitive attributes in terms of the revised set of 17 attributes. The girls had similar performance on the attributes as the boys. The students from the two eastern regions significantly underperformed on the most attributes.

Hauge, James Brian

1998-12-01

The College of Sciences and Mathematics Science Outreach Initiative was a program designed to attract students with the interest and ability to succeed in science and to keep them interested until they entered college. In this way, the Initiative sought to address the problem of a projected shortfall of scientists and engineers in the future. This study was conducted to evaluate the goals of the eighth grade component of the COSAM Initiative. These goals included: increased interest in and self-efficacy relating to science, increased achievement in science and mathematics, and increased enrollment in science and mathematics classes. Data were collected from 48 participants and 43 non-participants with surveys and from student records. Pre-treatment Chi-Square tests revealed that the groups did not differ in ethnicity, race, family income, parents' education, or parents' occupation. The surveys used were a total battery interest survey including (1) the Learning Science Things Survey (to measure interest in science topics), the Activities Interest Survey (to measure interest in science activities), the Career Orientation Survey (to measure interest in science careers) and the Learning Methods Survey (to measure interest in learning by experiential methods), (2) the Saturday Academy Survey (to measure self-efficacy concerning science activities), (3) the Saturday Academy Electronics/Eye Quiz (to test ability relating to science activities), and (4) the Summer Science Camp Survey (to measure interest in and self-efficacy concerning science activities). Student grades, SAT, and OLSAT scores, and the kinds of science and mathematics courses enrolled in during seventh and eighth grades were obtained from school records. Analysis of data using a mixed ANOVA design revealed that participation in the COSAM Initiative had no significant effect on interest in science as measured by the total battery survey. Similar analysis of Saturday Academy Survey data revealed that the

Open Adoption Placement by Birth Mothers in Their Twenties.

PubMed

Clutter, Lynn B

The purpose of this study was to summarize birth mothers' descriptions of unplanned pregnancy experienced in their twenties and how open adoption influenced their lives. Naturalistic inquiry was used with purposive sampling from one agency and telephone interviews of women who experienced unplanned pregnancy in their twenties and relinquishment through open adoption. Recorded, transcribed, and deidentified interviews were analyzed for qualitative themes. Fifteen participants judiciously weighed the open adoption decision. Over half parented other children prior to placement. Most knew they could not have parented this child due to life stressors. Placement was a hard decision, but ongoing contact with birth child and adoptive family was valued. Open adoption processes made them stronger by being happy that their child experienced family life with greater opportunities than birth mothers could offer at the time. Summarized themes used the acronym COMMITTED: C-care deeply about what is best for the child, O-ongoing open adoption: good and hard, M-meeting together regularly, M-moving on in personal growth, accomplishments, and milestones, I-independence from previous stressors or crises, T-transitions, T-therapeutic support, E-emotions, D-depression giving way to deepened strength and personal direction. Open adoption is reinforced as a positive resolution of unintended pregnancy for birth mothers in their twenties.

Environmental issues are the focal point in many parts of the world and scientists and ecologists undertake numerous activities to raise awareness of the citizens of the necessity to give their contribution to environmental protection. Discussing different ecological topics with our students, we came to the conclusion that they are only superficially aware of their role in the protection of nature. They do not fully realize that every contribution, no matter how small, means a lot. In order to inform them in more detail we first contacted the "RECAN" non-governmental foundation which is engaged in the protection of the environment, and they organized plenary lecture about recycling for our students. The seventh grade students attended this lecture. Consequently, they were involved in the project "Can by Can" and collected cans for recycling. But this time not only the seventh graders were involved. Our mission was to spread the word around the whole school and students from the first to the eighth grade participated and gave their contribution. Afterwards, Centre for the Talented Youth organized a workshop about the renewable energy sources for the students in eighth grade. They were given the opportunity to debate about energy sources, to express their own opinions and attitudes and to ask questions as well. All this was aimed at making our students more aware of their own responsibility for their environment and nature. Equipped with this newly acquired knowledge, our students conducted researches on the topic of solar panels and windmills and renewable energy solutions for houses.

Eighth-order explicit two-step hybrid methods with symmetric nodes and weights for solving orbital and oscillatory IVPs

NASA Astrophysics Data System (ADS)

Franco, J. M.; Rández, L.

The construction of new two-step hybrid (TSH) methods of explicit type with symmetric nodes and weights for the numerical integration of orbital and oscillatory second-order initial value problems (IVPs) is analyzed. These methods attain algebraic order eight with a computational cost of six or eight function evaluations per step (it is one of the lowest costs that we know in the literature) and they are optimal among the TSH methods in the sense that they reach a certain order of accuracy with minimal cost per step. The new TSH schemes also have high dispersion and dissipation orders (greater than 8) in order to be adapted to the solution of IVPs with oscillatory solutions. The numerical experiments carried out with several orbital and oscillatory problems show that the new eighth-order explicit TSH methods are more efficient than other standard TSH or Numerov-type methods proposed in the scientific literature.

Twenty-first century vaccines

PubMed Central

Rappuoli, Rino

2011-01-01

In the twentieth century, vaccination has been possibly the greatest revolution in health. Together with hygiene and antibiotics, vaccination led to the elimination of many childhood infectious diseases and contributed to the increase in disability-free life expectancy that in Western societies rose from 50 to 78–85 years (Crimmins, E. M. & Finch, C. E. 2006 Proc. Natl Acad. Sci. USA 103, 498–503; Kirkwood, T. B. 2008 Nat. Med 10, 1177–1185). In the twenty-first century, vaccination will be expected to eliminate the remaining childhood infectious diseases, such as meningococcal meningitis, respiratory syncytial virus, group A streptococcus, and will address the health challenges of this century such as those associated with ageing, antibiotic resistance, emerging infectious diseases and poverty. However, for this to happen, we need to increase the public trust in vaccination so that vaccines can be perceived as the best insurance against most diseases across all ages. PMID:21893537

Classical eighth- and lower-order Runge-Kutta-Nystroem formulas with a new stepsize control procedure for special second-order differential equations

NASA Technical Reports Server (NTRS)

Fehlberg, E.

1973-01-01

New Runge-Kutta-Nystrom formulas of the eighth, seventh, sixth, and fifth order are derived for the special second-order (vector) differential equation x = f (t,x). In contrast to Runge-Kutta-Nystrom formulas of an earlier NASA report, these formulas provide a stepsize control procedure based on the leading term of the local truncation error in x. This new procedure is more accurate than the earlier Runge-Kutta-Nystrom procedure (with stepsize control based on the leading term of the local truncation error in x) when integrating close to singularities. Two central orbits are presented as examples. For these orbits, the accuracy and speed of the formulas of this report are compared with those of Runge-Kutta-Nystrom and Runge-Kutta formulas of earlier NASA reports.

European CME Forum is a not-for-profit organisation that brings together all stakeholder groups with an interest in European continuing medical education (CME) and promote multichannel discussion in an independent and neutral environment. This report summarises the discussions that took place at the 8th Annual European CME Forum in Manchester on 11–12 November 2015. Held at a time of increased scrutiny on the quality and value of the CME, the forum provided a space for attendees to share perspectives on trends, challenges, and opportunities related to European CME accreditation, funding, and regulation. Discussions focused on specific “hot topics” identified through a pre-meeting survey and needs assessment conducted among CME stakeholders in Europe and beyond. Chief among these were issues related to managing the transparency of relationships between industry and healthcare professionals, evolving systems of European CME accreditation, and the future of CME funding. The programme structure included multiple workshops conducted by leaders in the CME field, and plenary sessions that facilitated multidisciplinary interactions with invited guests, including the very learners the CME field is designed to serve. Attendee feedback was gathered to begin shaping the programme for the 9th Annual European CME Forum (#9ECF), which will take place in Amsterdam, The Netherlands, on 9–11 November 2016. PMID:29644124

Ye, Bo; Zhao, Heng

2016-06-20

The currently adopted staging system for lung cancer is the seventh edition of the TNM staging edited by Union for International Cancer Control (UICC) in January, 2009. In recent years, with the advances of techniques in lung cancer diagnosis and the treatment trends towards precision treatment modalities such as individualized therapy and molecular targeted therapy, the survival and prognosis of lung cancer has been significantly improved. The old staging standard is difficult to satisfy the currentrapidly developing clinical needs. Therefore, the International Lung Cancer Research Society (International Association for the Study of Lung Cancer, IASLC) updated the stage of lung cancer in 2015, and the forthcoming eighth edition of the TNM Classification for Lung Cancer, which will be formally adopted in Jan. 2017, has been published in Journal of Thoracic Oncology. The new staging system has adopted 35 databases from 16 countries, including 94,708 cases treated between 1999 and 2010. The advantages of the new staging lies in its higher prognosis prediction and clinical guidance value.

Syme, S Leonard

2010-04-01

How can we translate the findings from public health research into practice? We are not doing this job very well and we need to rethink our approach so that we can do a better job. The major problem is that we public health professionals have messages to give people, but people have lives to lead, and we have not done well in closing this gap. To deal with this problem, we will need to learn how to better involve the community as an empowered partner in our work. To do that, we will have to fundamentally change our public health model: We will have to change the way we classify disease; we will have to change the way we organize and finance public health education; and we will have to deal with our arrogance. This plenary talk at the Eighth Annual Midwest Rural Agricultural Safety and Health Forum (MRASH), November 2009, described the importance of looking at health promotion and disease prevention not only at the level of the individual but also at the community and environmental level.

To evaluate a new, 1-h, condensed training programme to teach continuous chest compression cardiopulmonary resuscitation (CCC-CPR) and automated external defibrillator (AED) skills to a cohort of eight grade public school students. Thirty-three eligible subjects completed the programme; mean age 13.7 years; 48.5% female. Eight participants reported some prior training in CPR and AED use. Following initial training, 29/33 (87.8%) subjects demonstrated proficiency at CCC-CPR and AED application/operation in a mock adult cardiac arrest scenario. At four-weeks, 28/33 (84.8%) subjects demonstrated skill retention in similar scenario testing. Subjects also showed improvement in written knowledge regarding AED use as shown by scores on an AHA based written exam (60.9% versus 77.3%; p<0.001). With our focused, condensed training program, eighth grade public school students became proficient in CCC-CPR and AED use. This is the first study to document the ability of middle school students to learn and retain CCC-CPR and AED skills for adult sudden cardiac arrest victims with such a curriculum.

Sheehan's syndrome, first described in 1937, is characterised by postpartum haemorrhage, pituitary necrosis, lactational failure and hypopitutarism. Presentation is variable and late presentations are not unusual due to partial ischaemic injury of the pituitary and gradual loss of endocrine function. A history of postpartum haemorrhage is usual but in some cases it is not elicited. Presentations such as malaise, fatigue, hypoglycaemia, decline in cognition, hyponatraemia, pancytopoenia, osteoporosis, secondary infertility, confusion and coma have all been reported. Two interesting cases of Sheehan's syndrome are presented that were diagnosed in the eighth decade; one due to atypical presentation of recurrent hyponatraemia and confusion, another from hypoglycaemic coma and symptoms of malaise and lethargy.

Twenty-first century learning after school: the case of 4-H.

PubMed

Kress, Cathann

2006-01-01

Founded in the early 1900s, the 4-H Youth Development program can serve as a model for out-of-school programs of the twenty-first century. The 4-H pledge, repeated by its members--over 7 million, ranging in age from five to twenty--articulates its core values: "I pledge: My head to clearer thinking, My heart to greater loyalty, My hands to larger service, and My health to better living for my club, my community, my country, and my world." The 4-H Development movement was created to provide opportunities for rural children, to help them become constructive adults. Through an emphasis on "learning by doing," 4-H teaches children the habits of lifelong learning. Historically, 4-H has tapped into university-level advancements, extending such knowledge to youth and thereby giving them early access to scientific discoveries and technological progress. Members apply this learning in their communities through hands-on projects crossing a wide-range of pertinent topics. Research shows that 4-H members are more successful in school than other children and develop a wide range of skills essential in the twenty-first century. Thus, the author makes the case that the foundation of 4-H is exceptionally relevant in today's complex world, perhaps even more so than a century ago. 4-H is a leader in youth development, making it a natural model for twenty-first century after-school programs. Expanding on the 4-H pledge, the author outlines the principles a successful youth development program would have: an emphasis on leadership skills, a feeling of connection and belonging, a forum for exploring career opportunities, and a component of meaningful community service.

Can we conquer cancer in the twenty-first century?

PubMed

Freireich, E J

2001-08-01

The twentieth century recorded the greatest advance in the control of human disease. From the beginning of recorded time, the human life-span changed little until the twentieth century. In the USA, it increased from 47.3 years in 1900 to 76.4 years in 2000. The answer to the question of "Can we cure cancer in the twenty-first century?" requires an appreciation of the contemporary nature of our knowledge. At the beginning of the twentieth century, major problems were nutrition and infection. By 1950, the major causes of mortality and morbidity were still infectious diseases, such as syphilis, tuberculosis, poliomyelitis, and influenza. The 1950s and 1960s were the golden age of control of infectious diseases, while cancer, because of the aging of the population and the strong association between cancer and age, has become the major healthcare problem of the twenty-first century. Until 1960, no one had proposed or demonstrated that a systemic or metastatic form of cancer could be cured. In only 35-40 years not only have techniques for the early detection, prevention, and surgical and radiation therapy treatments improved, but at least 15-20% of patients with systemic/metastatic cancers can be cured with our current primitive systemic treatments. Prior to 1943, there was no chemotherapy. Prior to 1948, no one had described complete regression of a systemic cancer. There were no multi-institution, randomized clinical trials prior to 1949. Additionally, combination chemotherapy, new drugs, bone marrow transplantation, broad-spectrum antibiotics to control infections, and platelets to control hemorrhage have been added in the past 50 years. The pace of progress extrapolates to a prediction of cancer control in the twenty-first century. The human genome has been sequenced, and it will be possible to identify expression profiles not only for malignant cells but for their normal counterparts. It is certain that interventions specific for control of the malignant

Violante, Maria Grazia; Vezzetti, Enrico

2017-11-01

In the twenty-first century, meeting our technological challenges demands educational excellence, a skilled populace that is ready for the critical challenges society faces. There is widespread consensus, however, that education systems are failing to adequately prepare all students with the essential twenty-first century knowledge and skills necessary to succeed in life, career, and citizenship. The purpose of this paper is to understand how twenty-first century knowledge and skills can be appropriately embedded in engineering education finalised to innovative product development by using additive manufacturing (AM). The study designs a learning model by which to achieve effective AM education to address the requirements of twenty-first century and to offer students the occasion to experiment with STEM (Science, technology, engineering, and mathematics) concepts. The study is conducted using the quality function deployment (QFD) methodology.

The American Joint Committee on Cancer (AJCC) staging manual has become the benchmark for classifying patients with cancer, defining prognosis, and determining the best treatment approaches. Many view the primary role of the tumor, lymph node, metastasis (TNM) system as that of a standardized classification system for evaluating cancer at a population level in terms of the extent of disease, both at initial presentation and after surgical treatment, and the overall impact of improvements in cancer treatment. The rapid evolution of knowledge in cancer biology and the discovery and validation of biologic factors that predict cancer outcome and response to treatment with better accuracy have led some cancer experts to question the utility of a TNM-based approach in clinical care at an individualized patient level. In the Eighth Edition of the AJCC Cancer Staging Manual, the goal of including relevant, nonanatomic (including molecular) factors has been foremost, although changes are made only when there is strong evidence for inclusion. The editorial board viewed this iteration as a proactive effort to continue to build the important bridge from a "population-based" to a more "personalized" approach to patient classification, one that forms the conceptual framework and foundation of cancer staging in the era of precision molecular oncology. The AJCC promulgates best staging practices through each new edition in an effort to provide cancer care providers with a powerful, knowledge-based resource for the battle against cancer. In this commentary, the authors highlight the overall organizational and structural changes as well as "what's new" in the Eighth Edition. It is hoped that this information will provide the reader with a better understanding of the rationale behind the aggregate proposed changes and the exciting developments in the upcoming edition.

Twenty-four-hour ambulatory blood pressure monitoring for clinical evaluation of hypertensive patients in primary care: which groups would most benefit?

PubMed

Grezzana, Guilherme B; Stein, Airton T; Pellanda, Lucia C

2017-04-01

Arterial hypertension is an important risk factor for cardiovascular outcomes. Blood pressure (BP) control levels remain largely out of target among primary healthcare (PHC) patients. Twenty-four-hour ambulatory blood pressure monitoring (ABPM) may contribute toward the identification of cardiovascular risk groups. To assess concordance between conventional office BP measurements and 24-h ABPM of hypertension control in cardiovascular risk groups of PHC hypertensive patients. A cross-sectional study with 569 hypertensive patients was carried out. The evaluation of BP was performed by a PHC doctor, and the 24-h ABPM was performed by a different and blinded provider. The therapeutic targets for BP followed the guidance of The Eighth Joint National Committee, the Brazilian guideline, and the 2013 European Society of Hypertension. Considering the hypertension control therapeutic targets, the guidelines were not similar and were used to evaluate differences in BP value concordances compared with BP standard measurements. After a multivariate logistic regression analysis, a conventional BP was used in comparison with ABPM in different cardiovascular risk groups of hypertensive patients. According to the ABPM by European Society of Hypertension guideline, the subgroup of inactive patients (P=0.006), with altered glycemia (P=0.015) and over 30 mg/dl albuminuria (P=0.001), presented discordance among methods. When a conventional BP measurement in comparison with the ABPM results according to the Brazilian ABPM guideline was used, the discordance occurred significantly in inactive (P=0.001) and microalbuminuria more than 30 mg/dl (P=0.022) subgroups. However, in this comparison, a concordance between high-density lipoprotein more than 60 mg/dl (P=0.015) and obesity (P=0.035) subgroups occurred. Uncontrolled glucose levels, a sedentary lifestyle, and the presence of microalbuminuria correspond to some cardiovascular risk groups that would particularly benefit from 24-h

Taverno Ross, Sharon E; Dowda, Marsha; Beets, Michael W; Pate, Russell R

2013-06-01

Although girls are generally less physically active than boys, some girls regularly engage in high levels of physical activity (PA); however, very little is known about these girls and how they differ from those who are less physically active. This study examined the PA behavior and related characteristics of highly active adolescent girls and compared them with those who are less active. Data from 1,866 eighth-grade girls from six field centers across the United States participating in the Trial of Activity for Adolescent Girls (TAAG) were included in the present analysis. Mixed-model analysis of variance examined differences in sociodemographic, anthropometric, psychosocial, and physical activity (accelerometry and self-report) variables between high- and low-active girls; effect sizes were calculated for the differences. High-active girls were taller, had lower body mass indices and body fat, and were less sedentary. High-active girls scored higher on self-efficacy, enjoyment of PA, self-management strategies, outcome-expectancy value, and support from family and friends than low-active girls. Low-active girls participated in more leisure time and educational sedentary activities than high-active girls. High-active girls participated in more PA classes/lessons outside of school, team sports, and individual sports. They were also more likely to participate in sports in an organized setting in the community or at school than low-active girls. Health promotion efforts should focus on decreasing the amount of time girls spend in sedentary activities and replacing that time with organized PA opportunities; such efforts should seek to minimize perceived barriers and increase self-efficacy and support for PA.

2012-02-01

The goal of this study was to test the effectiveness of integrating science and societal implication on adolescents' positive thinking and emotional perceptions about learning science. Twenty-five eighth-grade Taiwanese adolescents (9 boys and 16 girls) volunteered to participate in a 12-week intervention and formed the experimental group. Fifty-seven eighth-grade Taiwanese adolescents (30 boys and 27 girls) volunteered to participate in the assessments and were used as the comparison group. Additionally, 15 experimental students were recruited to be observed and interviewed. Paired t-tests, correlations, and analyses of covariance assessed the similarity and differences between groups. The findings were that the experimental group significantly outperformed its counterpart on positive thinking and emotional perceptions, and all participants' positive thinking scores were significantly related to their emotional perceptions about learning science. Recommendations for integrating science and societal implication for adolescents are provided.

2010-01-01

Sheehan’s syndrome, first described in 1937, is characterised by postpartum haemorrhage, pituitary necrosis, lactational failure and hypopitutarism. Presentation is variable and late presentations are not unusual due to partial ischaemic injury of the pituitary and gradual loss of endocrine function. A history of postpartum haemorrhage is usual but in some cases it is not elicited. Presentations such as malaise, fatigue, hypoglycaemia, decline in cognition, hyponatraemia, pancytopoenia, osteoporosis, secondary infertility, confusion and coma have all been reported. Two interesting cases of Sheehan’s syndrome are presented that were diagnosed in the eighth decade; one due to atypical presentation of recurrent hyponatraemia and confusion, another from hypoglycaemic coma and symptoms of malaise and lethargy.

Twenty-first century learning for teachers: helping educators bring new skills into the classroom.

PubMed

Wilson, John I

2006-01-01

The motivation behind every educator's dedication and hard work in the classroom is the knowledge that his or her teaching will result in students' success in life. Educators are committed to implementing twenty-first century skills; they have no question that students need such skills to be equipped for life beyond school. Members of the National Education Association are enthusiastic about the Partnership for 21st Century Skills framework, yet express frustration that many schools do not have adequate resources to make the necessary changes. Teaching these skills poses significant new responsibilities for schools and educators. To make it possible for teachers to build twenty-first century skills into the curriculum, physical and policy infrastructures must exist, professional development and curriculum materials must be offered, and meaningful assessments must be available. With an established understanding of what skills need to be infused into the classroom-problem solving, analysis, and com- munications-and educators' commitment to the new skill set, this chapter explores how to make such a dramatic reform happen. The author discusses existing strategies that will guide educators in infusing twenty-first century skills into traditional content areas such as math, English, geography, and science. Ultimately, public policy regarding educational standards, professional development, assessments, and physical school structures must exist to enable educators to employ twenty-first century skills, leading to student success in contemporary life. Any concern about the cost of bringing this nation's educational system up to par internationally should be offset by the price that not making twenty-first century skills a priority in the classroom will have on future economic well-being.

Larval development to the first eighth zoeal stages in the deep-sea caridean shrimp Plesionika grandis Doflein, 1902 (Crustacea, Decapoda, Pandalidae).

Jiang, Guo-Chen; Chan, Tin-Yam; Shih, Tung-Wei

2017-01-01

The larvae of the deep-sea pandalid shrimp Plesionika grandis Doflein, 1902 were successfully reared in the laboratory for the first time. The larvae reached the eighth zoeal stage in 36 days, both of which are longest records for the genus. Early larval stages of P. grandis bear the general characters of pandalid shrimps and differ from the other two species of Plesionika with larval morphology known in the number of spines on the anteroventral margin of carapace, number of tubercles on antennule, endopod segmentation in antenna, and third maxilliped setation. Although members in Plesionika are often separated into species groups, members of the same species group do not necessarily have similar early larval morphology. Since the zoea VIII of P. grandis still lacks pleopods and fifth pereiopod, this shrimp likely has at least 12 zoeal stages and a larval development of 120 days.

Estimates of twenty-first century sea-level changes for Norway

NASA Astrophysics Data System (ADS)

Simpson, Matthew J. R.; Breili, Kristian; Kierulf, Halfdan P.

2014-03-01

In this work we establish a framework for estimating future regional sea-level changes for Norway. Following recently published works, we consider how different physical processes drive non-uniform sea-level changes by accounting for spatial variations in (1) ocean density and circulation (2) ice and ocean mass changes and associated gravitational effects on sea level and (3) vertical land motion arising from past surface loading change and associated gravitational effects on sea level. An important component of past and present sea-level change in Norway is glacial isostatic adjustment. Central to our study, therefore, is a reassessment of vertical land motion using a far larger set of new observations from a permanent GNSS network. Our twenty-first century sea-level estimates are split into two parts. Firstly, we show regional projections largely based on findings from the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR4) and dependent on the emission scenarios A2, A1B and B1. These indicate that twenty-first century relative sea-level changes in Norway will vary between -0.2 to 0.3 m (1-sigma ± 0.13 m). Secondly, we explore a high-end scenario, in which a global atmospheric temperature rise of up to 6 °C and emerging collapse for some areas of the Antarctic ice sheets are assumed. Using this approach twenty-first century relative sea-level changes in Norway are found to vary between 0.25 and 0.85 m (min/max ± 0.45 m). We attach no likelihood to any of our projections owing to the lack of understanding of some of the processes that cause sea-level change.

Pearlman, Bob

2006-01-01

The most pertinent question concerning teaching and learning in the twenty-first century is not what knowledge and skills students need--that laundry list was identified over a decade ago--but rather how to foster twenty-first century learning. What curricula, experiences, assessments, environments, and technology best support twenty-first century learning? New Technology High School (NTHS) in Napa, California, is one example of a successful twenty-first century school. In this chapter, the author describes the components of this exemplary high school, illustrating an environment that will cultivate twenty-first century student learning. New Technology High School began by defining eight learning outcomes, aligned with the standards of the Partnership for 21st Century Skills; to graduate, students demonstrate mastery of these outcomes through an online portfolio. To help students achieve the outcomes, NTHS employs project- and problem-based learning. Whereas in traditional classrooms students work alone on short-term assignments that do not lend themselves to deep understanding, the project-based learning approach has students working in teams on long-term, in-depth, rigorous projects. Students' work is supported by the school's workplace-like environment and effectiv use of technology. Meaningful assessment is essential to project-based learning; students receive continuous feedback, helping them become self-directed learners. In fact, NTHS uses outcome-based grading through which students constantly know how they are performing on the twenty-first century outcomes. Research has shown that NTHS graduates are better prepared for postsecondary education, careers, and citizenship than their peers from other schools. To facilitate twenty-first century learning, all schools need to rethink their approach to teaching and learning. New Technology High School is one way to do so.

To evaluate the efficacy and prognostic validity for disease-specific survival (DSS) of the eighth edition American Joint Committee on Cancer/Union for International Cancer Control tumor-node-metastasis (TNM) staging system (TNM-8) compared to the seventh edition (TNM-7) in patients with differentiated thyroid carcinoma (DTC). The seventh and eighth editions of the TNM staging system were applied to 1613 DTC patients who underwent thyroid surgery between 1996 and 2003. The proportion of variation explained and Harrell's c-index were evaluated to compare the predictive capability of DSS. The mean age of the patients was 44.7 years, and the median follow-up period was 11.2 years. When TNM-8 was applied, 63% of T3 and 3% of N1b DTCs were downgraded to T1/T2 and N1a, respectively. About 38% of patients were downstaged according to TNM-8. The 10-year DSS rates in TNM-7 stages I, II, III, and IV were 99.7%, 98.2%, 98.8%, and 83.2%, respectively. Those in TNM-8 stages I, II, III, and IV were 99.6%, 95.4%, 72.3%, and 48.6%, respectively. The proportion of variation explained values of TNM-7 and TNM-8 were 6.0% and 7.0%, respectively. The Harrell's c-index of TNM-7 was 0.86 and that of TNM-8 was 0.88. A significant number of patients were reclassified to lower stages with the application of TNM-8 compared to TNM-7. Applying TNM-8 could improve the accuracy of the staging system for predicting DSS in patients with DTC.

1993-02-01

The eighth International Symposium on the Applications of Ferroelectrics was held in Greenville, SC, on August 30 to Sept 2, 1992. It was attended by approximately 260 scientists and engineers who presented nearly 200 oral and poster papers. The three plenary presentations covered ferroelectric materials which are currently moving into commercial exploitation or have strong potential to do so. These were (1) pyroelectric imaging, (2) ferroelectric materials integrated with silicon for use as micromotors and microsensors and (3) research activity in Japan on high permittivity materials for DRAM's. Invited papers covered such subjects as pyroelectric and electrooptic properties of thin films, photorefractive effects, ferroelectric polymers, piezoelectric transducers, processing of ferroelectrics, domain switching in ferroelectrics, thin film memories, thin film vacuum deposition techniques and the fabrication of chemically prepared PZT and PLZT thin films. The papers continued to reflect the large interest in ferroelectric thin films. It was encouraging that there have been substantial strides made in both the processing and understanding of the films in the last two years. It was equally clear, however, that much still remains to be done before reliable thin film devices will be available in the marketplace.

Results are presented of treatment with miconazole, orally and intravenously, in patients with paracoccidioidomycosis. Twenty-eight male patients aged from 34 to 66 years and exhibiting various clinical forms of the disease were studied. Twenty-five came from endemic areas in north east Argentina (Chaco, Formosa, Misiones, Corrientes and northern Santa Fe) and the remaining three from Paraguay. Twenty patients were engaged in agricultural work or at woodmills. single or multiple lesions were observed in 24 cases. Thirteen were suffering from infection of the larynx and in two of them a tracheotomy was necessary. Twenty-three showed pulmonary lesions on X-rays. Twelve had ganglionic lesions, eight had cutaneous lesions and one patient had osteoarthritis of the knee. One patient had hepatomegaly which was unrelated to chronic alcoholism. Fourteen patients had received previous treatments such as sulphonamides and amphotericin B (7 cases); sulphonamides (3), sulphonamides and the combination sulfamethoxazole + trimethoprim (3), and one patient had received all three medications. All patients had relapsed before starting miconazole therapy. Diagnosis was established by the presence of P. brasiliensis in all cases, recovered either from cutaneous or mucosal biopsy samples or from the sputum. Complement fixation tests were positive in all patients at the onset of the treatment and the immunodiffusion reactions showed precipitation bands in 27/28 patients. Skin tests with P. brasiliensis antigens proved to be positive in 18 cases and negative in 10. The erythrocyte sedimentation rate was markedly accelerated in 22 patients (greater than 20 mm in the first hour).(ABSTRACT TRUNCATED AT 250 WORDS) Images p24-a Fig 1 Fig 2 PMID:122643

Ledger, Antoinette Frances

This study sought to examine whether collaborative concept mapping would affect the achievement, science self-efficacy and attitude toward science of female eighth grade science students. The research questions are: (1) Will the use of collaborative concept mapping affect the achievement of female students in science? (2) Will the use of collaborative concept mapping affect the science self-efficacy of female students? (3) Will the use of collaborative concept mapping affect the attitudes of females toward science? The study was quasi-experimental and utilized a pretest-posttest design for both experimental and control groups. Eighth grade female and male students from three schools in a large northeastern school district participated in this study. The achievement test consisted of 10 multiple choice and two open-response questions and used questions from state-wide and national assessments as well as teacher-constructed items. A 29 item Likert type instrument (McMillan, 1992) was administered to measure science self-efficacy and attitude toward science. The study was of 12 weeks duration. During the study, experimental group students were asked to perform collaborative concept map construction in single sex dyads using specific terms designated by the classroom teacher and the researcher. During classroom visitations, student perceptions of collaborative concept mapping were collected and were used to provide insight into the results of the quantitative data analysis. Data from the pre and posttest instruments were analyzed for both experimental and control groups using t-tests. Additionally, the three teachers were interviewed and their perceptions of the study were also used to gain insight into the results of the study. The analysis of data showed that experimental group females showed significantly higher gains in achievement than control group females. An additional analysis of data showed experimental group males showed significantly greater gains in

The history of vaccination clearly demonstrates that vaccines have been highly successful in preventing infectious diseases, reducing significantly the incidence of childhood diseases and mortality. However, many infections are still not preventable with the currently available vaccines and they represent a major cause of mortality worldwide. In the twenty-first century, the innovation brought by novel technologies in antigen discovery and formulation together with a deeper knowledge of the human immune responses are paving the way for the development of new vaccines. Final goal will be to rationally design effective vaccines where conventional approaches have failed. PMID:24478777

Why American business demands twenty-first century skills: an industry perspective.

PubMed

Bruett, Karen

2006-01-01

Public education is the key to individual and business prosperity. With a vested stake in education, educators, employers, parents, policymakers, and the public should question how this nation's public education system is faring. Knowing that recent international assessments have shown little or no gains in American students' achievement, the author asserts the clear need for change. As both a large American corporate employer and a provider of technology for schools, Dell is concerned with ensuring that youth will thrive in their adult lives. Changing workplace expectations lead to a new list of skills students will need to acquire before completing their schooling. Through technology, Dell supports schools in meeting educational goals, striving to supply students with the necessary skills, referred to as twenty-first century skills. The Partnership for 21st Century Skills, of which Dell is a member, has led an initiative to define what twenty-first century learning should entail. Through extensive research, the partnership has built a framework outlining twenty-first century skills: analytical thinking, communication, collaboration, global awareness, and technological and economic literacy. Dell and the partnership are working state by state to promote the integration of these skills into curricula, professional development for teachers, and classroom environments. The authors describe two current initiatives, one in Virginia, the other in Texas, which both use technology to help student learning. All stakeholders can take part in preparing young people to compete in the global economy. Educators and administrators, legislators, parents, and employers must play their role in helping students be ready for what the workforce and the world has in store for them.

As twenty-first century skills become a greater focus in K-12 education, an infusion of technology that meets the needs of today's students is paramount. This study looks at the design and creation of a Multiplayer Educational Gaming Application (MEGA) for high school biology students. The quasi-experimental, qualitative design assessed the twenty-first century skills of digital age literacy, inventive thinking, high productivity, and effective communication techniques of the students exposed to a MEGA. Three factors, as they pertained to these skills, emerged from classroom observations. Interaction with the teacher, discussion with peers, and engagement/time-on-task while playing the MEGA suggested that students playing an educational video game exhibited all of the projected twenty-first century skills while being engrossed in the embedded science content.

Drastic Aridification Caused the Decline of Oasis Civilizations on the Silk Route during the Eighth Century

Availability of water, and response to shortage of it, plays an important role in shaping human history. Near a century ago, Ellsworth Huntington (1907) suggested that the developments of ancient civilizations in Inner Asian and their invasions into China and Europe were pulsed by climatic changes. In revisiting this proposition, here we present a paleoclimatic record of the past 5000 years deduced from carbon isotopic ratio of organic carbon and percentage of aragonite in bulk sediments of a radiometrically dated sedimentary core of Lake Bosten, Xinjiang, China. Together the two proxies of aridity provide a detailed record of climatic fluctuation of the Inner Asia. The arid periods are well characterized by high content of authigenic aragonite and heavier values of carbon isotopic ratio of organic carbon in the bulk sediments (implying dominance of C4 plants which thrived under arid condition). Conversely, the humid/wet periods are marked by lighter carbon isotopic values (indicating presence of C3 plants of humid climateœcand absence of aragonite. The Western Region (Xi-Y"1) area of China enjoyed a long period of stable and humid condition from 2nd century B.C. to the 8th century when many oasis city-states were established and Buddhism spread from India. A drastic deterioration of climate during the eighth century appears to cause the decline of those once strived ancient civilizations in the eastern side of the Tarim Basin along the Silk Routes.

Science Teacher Education in the Twenty-First Century: a Pedagogical Framework for Technology-Integrated Social Constructivism

NASA Astrophysics Data System (ADS)

Barak, Miri

2017-04-01

Changes in our global world have shifted the skill demands from acquisition of structured knowledge to mastery of skills, often referred to as twenty-first century competencies. Given these changes, a sequential explanatory mixed methods study was undertaken to (a) examine predominant instructional methods and technologies used by teacher educators, (b) identify attributes for learning and teaching in the twenty-first century, and (c) develop a pedagogical framework for promoting meaningful usage of advanced technologies. Quantitative and qualitative data were collected via an online survey, personal interviews, and written reflections with science teacher educators and student teachers. Findings indicated that teacher educators do not provide sufficient models for the promotion of reform-based practice via web 2.0 environments, such as Wikis, blogs, social networks, or other cloud technologies. Findings also indicated four attributes for teaching and learning in the twenty-first century: (a) adapting to frequent changes and uncertain situations, (b) collaborating and communicating in decentralized environments, (c) generating data and managing information, and (d) releasing control by encouraging exploration. Guided by social constructivist paradigms and twenty-first century teaching attributes, this study suggests a pedagogical framework for fostering meaningful usage of advanced technologies in science teacher education courses.

Attitudes of eighth-grade honors students toward the conceptual change methods of teaching science

NASA Astrophysics Data System (ADS)

Heide, Clifford Lee

1998-12-01

The study researched the attitude of eighth grade honors science students toward the steps of the conceptual change teaching method. The attitudes of 25 students in an honors 8th grade science class in the Greater Phoenix metropolitan area were assessed using a multi-method approach. A quantitative method (student survey) and a qualitative method (focus group) were triangulated for convergence. Since conceptual change is a relatively new reform teaching modality, the study assessed students' attitudes utilizing this method. Conceptual change teaching is characterized by connections between concepts and facts which are organized around key ideas. Knowledge connected through concepts is constantly revised and edited by students as they continue to learn and add new concepts. The results of this study produced evidence that the conceptual change method of teaching science and its six process steps have qualities that foster positive student attitude. The study demonstrated that students' attitudes toward science is positively influenced through the conceptual change teaching method by enabling students to: (1) choose problems and find solutions to those problems (student directed); (2) work together in large and small groups; (3) learn through student oral presentations; (4) perform hands-on laboratory experiences; (5) learn through conceptual understanding not memorization; (6) implement higher order learning skills to make connections from the lab to the real world. Teachers can use the information in the study to become aware of the positive and negative attitudes of students taught with the conceptual change method. Even if the conceptual change teaching strategy is not the modality utilized by an educator, the factors identified by this study that affect student attitude could be used to help a teacher design lesson plans that help foster positive student attitudes.

2018-01-01

While pipeline programs for students from underrepresented minority groups have been established at the high school and college levels, fewer programs have been developed for middle school students. In an effort to reach this cohort, the University of Detroit Mercy School of Dentistry embarked on a grassroots collaborative pipeline program with two distinct segments: Urban Impressions and Dental Imprint. Their purpose is to expose Detroit-area seventh and eighth grade students to careers in dentistry, provide oral health education, and introduce role models. The aim of this pilot study was to determine outcomes for the middle school participants in Urban Impressions (n=86) and Dental Imprint (n=68). Both segments featured hands-on dental activities at the dental school. Outcomes were assessed by pretest-posttest surveys. Across the three cohorts, a total of 86 students participated in one or more sessions, with 57 completing the pre- and post-program surveys, for a 66% response rate. The results showed that the Dental Imprint respondents' knowledge of oral health, dental admissions, and specialties increased by an average 26% over three years. The gain in knowledge for each cohort was statistically significant (p<0.001). Overall, 91% of Urban Impressions and 95% of Dental Imprint respondents were positive about the value of the program. Thirty-one of 57 Urban Impressions respondents indicated interest in dentistry as a career following the program. These results suggest that the two segments of this program are meeting their goals of increasing middle grade students' awareness of oral health professions including dentistry and providing access to role models. Institutions may benefit from the description of strategies used by this program to address challenges related to establishing early pipeline programs.

Ozone distributions have been derived from recent satellite-based measurements by the Stratospheric Aerosol and Gas Experiment (SAGE), the Halogen Occultation Experiment (HALOE) and the Microwave Limb Sounder (MLS). An ozone distribution for the period April 1992 to March 1993 and covering pressures from 0.1 to 100 mb and from 80 deg N to 80 deg S is summarized. At pressures less than 1 mb, separate distributions are given for daytime and nighttime conditions. The resulting distributions extend to somewhat higher latitudes and lower altitudes than previous COSPAR reference atmosphere distributions for ozone. Differences versus the most recent COSPAR distribution by Keating et al are illustrated.

An examination of gender bias on the eighth-grade MEAP science test as it relates to the Hunter Gatherer Theory of Spatial Sex Differences

Armstrong-Hall, Judy Gail

The purpose of this study was to apply the Hunter-Gatherer Theory of sex spatial skills to responses to individual questions by eighth grade students on the Science component of the Michigan Educational Assessment Program (MEAP) to determine if sex bias was inherent in the test. The Hunter-Gatherer Theory on Spatial Sex Differences, an original theory, that suggested a spatial dimorphism concept with female spatial skill of pattern recall of unconnected items and male spatial skills requiring mental movement. This is the first attempt to apply the Hunter-Gatherer Theory on Spatial Sex Differences to a standardized test. An overall hypothesis suggested that the Hunter-Gatherer Theory of Spatial Sex Differences could predict that males would perform better on problems involving mental movement and females would do better on problems involving the pattern recall of unconnected items. Responses to questions on the 1994-95 MEAP requiring the use of male spatial skills and female spatial skills were analyzed for 5,155 eighth grade students. A panel composed of five educators and a theory developer determined which test items involved the use of male and female spatial skills. A MANOVA, using a random sample of 20% of the 5,155 students to compare male and female correct scores, was statistically significant, with males having higher scores on male spatial skills items and females having higher scores on female spatial skills items. Pearson product moment correlation analyses produced a positive correlation for both male and female performance on both types of spatial skills. The Hunter-Gatherer Theory of Spatial Sex Differences appears to be able to predict that males could perform better on the problems involving mental movement and females could perform better on problems involving the pattern recall of unconnected items. Recommendations for further research included: examination of male/female spatial skill differences at early elementary and high school levels to

It is twenty years since the seminal works by Magorrian and co-authors and by Silk and Rees, which, along with other related work, ignited an explosion of publications connecting active galactic nucleus (AGN)-driven outflows to galaxy evolution. With a surge in observations of AGN outflows, studies are attempting to test AGN feedback models directly using the outflow properties. With a focus on outflows traced by optical and CO emission lines, we discuss significant challenges that greatly complicate this task, from both an observational and theoretical perspective. We highlight the observational uncertainties involved and the assumptions required when deriving kinetic coupling efficiencies (that is, outflow kinetic power as a fraction of AGN luminosity) from typical observations. Based on recent models we demonstrate that extreme caution should be taken when comparing observationally derived kinetic coupling efficiencies to coupling efficiencies from fiducial feedback models.

Shelter for the twenty-first century.

Housing for the twenty-first century will be shaped by the changes that are occurring in society. These include the demographics of the occupant, the products and materials used for construction and furnishing, and the basic use of the structure. An aging population will have different demands on design and function. The health concerns of an aging population encompass chronic degenerative diseases as well as injury. The lessons of the past must make us mindful that chronic, low-level exposures to substances can occur at home. Products and materials used in homes can release vapors that may affect immunologic and neurologic function. Manifestations of dysfunctions will be more important as our population ages and if there is a continued reliance on new chemical formulation for products used in homes and workplaces. The future portends changes in functional use of residences. Electronic communications and robotics will decentralize our work force. Manufacturing or office functions will occur at home. This will present new challenges for health and safety for both monitoring and prevention. PMID:2401266

The Hospital for Special Surgery 1972–1989; Philip D. Wilson, Jr., Eighth Surgeon-in-Chief

PubMed Central

2010-01-01

After nearly a decade as the seventh Surgeon-in-Chief (1963–1972) of The Hospital for Special Surgery (HSS), Robert Lee Patterson, Jr., MD (1907–1994) retired, having repaired adverse relations between HSS and the New York Hospital-Cornell Medical Center. Patterson, who had first joined the staff of The Hospital for the Ruptured and Crippled in 1936 as a Visiting Surgeon, was able to accomplish this very challenging task mainly through his close relationship with Preston Wade, MD (1901–1982), a general surgeon who had served with Patterson as Co-Chief of the combined New York Hospital-HSS Fracture service. The Board of Trustees of the New York Society for the Relief of the Ruptured and Crippled appointed Philip D. Wilson, Jr. MD, as the eighth Surgeon-in-Chief of The Hospital for Special Surgery. He assumed that office on July 1, 1972. Wilson, who had joined the staff as an Orthopaedic Surgeon to the Out-Patient Department in 1951, had trained as an orthopaedic resident at HSS from 1948 to 1950 and in 1951, finished his residency at the University of California Hospital Medical Center, San Francisco. During his 17 years as Surgeon-in-Chief, he led the hospital into the advanced field of implant research and development and building a world-class center for patient care. Additionally, many other orthopaedic services such as Sports Medicine, Scoliosis and Metabolic Bone Diseases became the leaders in their fields. Supporting Departments of Rheumatology, Anesthesia and others were likewise recognized foremost in the country. PMID:21886524

With infection once again a high priority for the UK National Health Service (NHS), the medical microbiology and infection-control services require increased technology resources and more multidisciplinary staff. Clinical care and health protection need a coordinated network of microbiology services working to consistent standards, provided locally by NHS Trusts and supported by the regional expertise and national reference laboratories of the new Health Protection Agency. Here, I outline my thoughts on the need for these new resources and the ways in which clinical microbiology services in the UK can best meet the demands of the twenty-first century.

Answer questions and earn CME/CNE The recently released eighth edition of the American Joint Committee on Cancer (AJCC) Staging Manual, Head and Neck Section, introduces significant modifications from the prior seventh edition. This article details several of the most significant modifications, and the rationale for the revisions, to alert the reader to evolution of the field. The most significant update creates a separate staging algorithm for high-risk human papillomavirus-associated cancer of the oropharynx, distinguishing it from oropharyngeal cancer with other causes. Other modifications include: the reorganizing of skin cancer (other than melanoma and Merkel cell carcinoma) from a general chapter for the entire body to a head and neck-specific cutaneous malignancies chapter; division of cancer of the pharynx into 3 separate chapters; changes to the tumor (T) categories for oral cavity, skin, and nasopharynx; and the addition of extranodal cancer extension to lymph node category (N) in all but the viral-related cancers and mucosal melanoma. The Head and Neck Task Force worked with colleagues around the world to derive a staging system that reflects ongoing changes in head and neck oncology; it remains user friendly and consistent with the traditional tumor, lymph node, metastasis (TNM) staging paradigm.

Final Plenary Session Transcript

Gostelow, Paul

2010-01-01

Let s start with the report - as you know - when we are talking about flow control it is a multi-disciplinary type of work. So it involves many people and disciplines. This group first discussed the important issues associated with flow control. As you start doing flow control what are the issues to which you really have to start paying attention? That is the first part I am going to present. Then in the second part I will present some challenges - problems that we should really be looking at. So as far as the issues - if you want to control a flow, you really need to understand the flow physics, because anything that you do comes from the flow physics. The design of the controllers, your decisions on the actuators, sensors, reduced order modeling and all of that, would be helped if you understand flow physics. And you have to have a specific objective - what exactly are you controlling? Are you trying to reduce drag, eliminate separation, reduce noise, enhance mixing? So you have to have very specific control objectives. From all the talks we have seen here actuation is extremely important and it is very problem specific. It depends on what problem you are dealing with so you have to design and build actuators for that specific problem. Sensors obviously are very important, especially when you are dealing with feedback control. Consensus was that when you dealing with flow control, you must take an integrated approach; from the beginning you have to take into account every aspect of it and even maybe to modify your experiment, your geometry, to go along with the actuation, sensors and control models. Development of tools is very important in this multi-disciplinary problem. The tools include CFD, reduced order modeling, controller design, understanding and utilizing the instabilities of the flow, etc. So, in order to have success in flow control, we really need to develop these tools.

Twenty-first century science as a relational process: from eureka! to team science and a place for community psychology.

PubMed

Tebes, Jacob Kraemer; Thai, Nghi D; Matlin, Samantha L

2014-06-01

In this paper we maintain that twenty-first century science is, fundamentally, a relational process in which knowledge is produced (or co-produced) through transactions among researchers or among researchers and public stakeholders. We offer an expanded perspective on the practice of twenty-first century science, the production of scientific knowledge, and what community psychology can contribute to these developments. We argue that: (1) trends in science show that research is increasingly being conducted in teams; (2) scientific teams, such as transdisciplinary teams of researchers or of researchers collaborating with various public stakeholders, are better able to address complex challenges; (3) transdisciplinary scientific teams are part of the larger, twenty-first century transformation in science; (4) the concept of heterarchy is a heuristic for team science aligned with this transformation; (5) a contemporary philosophy of science known as perspectivism provides an essential foundation to advance twenty-first century science; and (6) community psychology, through its core principles and practice competencies, offers theoretical and practical expertise for advancing team science and the transformation in science currently underway. We discuss the implications of these points and illustrate them briefly with two examples of transdisciplinary team science from our own work. We conclude that a new narrative is emerging for science in the twenty-first century that draws on interpersonal transactions in teams, and active engagement by researchers with the public to address critical accountabilities. Because of its core organizing principles and unique blend of expertise on the intersection of research and practice, community psychologists are well-prepared to help advance these developments, and thus have much to offer twenty-first century science.
