  10. Middle school science curriculum design and 8th grade student achievement in Massachusetts public schools

    NASA Astrophysics Data System (ADS)

    Clifford, Betsey A.

    The Massachusetts Department of Elementary and Secondary Education (DESE) released proposed Science and Technology/Engineering standards in 2013 outlining the concepts that should be taught at each grade level. Previously, standards were in grade spans and each district determined the method of implementation. There are two different methods used teaching middle school science: integrated and discipline-based. In the proposed standards, the Massachusetts DESE uses grade-by-grade standards using an integrated approach. It was not known if there is a statistically significant difference in student achievement on the 8th grade science MCAS assessment for students taught with an integrated or discipline-based approach. The results on the 8th grade science MCAS test from six public school districts from 2010 -- 2013 were collected and analyzed. The methodology used was quantitative. Results of an ANOVA showed that there was no statistically significant difference in overall student achievement between the two curriculum models. Furthermore, there was no statistically significant difference for the various domains: Earth and Space Science, Life Science, Physical Science, and Technology/Engineering. This information is useful for districts hesitant to make the change from a discipline-based approach to an integrated approach. More research should be conducted on this topic with a larger sample size to better support the results.

    Kaleli-Yılmaz, Gül; Hanci, Alper

    2016-07-01

    The aim of this study is to determine how the TIMSS mathematics success of the 8th grade students differentiates according to the school type, gender, mathematics report mark, parents' education level, cognitive domains and cognitive domains by gender. Relational survey method was used in the study. Six-hundred fifty two 8th grade students studying in the same city in Turkey participated in this study. In this study, a 45 question test that was made up by choosing TIMSS 2011 mathematics questionnaire was used as a data collection tool. Quantitative data analysis methods were used in the data analysis, frequency, percentage, average, standard deviation, independent sample test, one-way analysis of variance and post-hoc tests were applied to data by using SPSS packaged software. At the end of the study, it was determined that the school type, mathematics school mark, parents' education level and cognitive domains influenced the students' TIMSS mathematics success but their gender was a neutral element. Moreover, it was seen that schools which are really successful in national exams are more successful in TIMSS exam; students whose mathematics school marks are 5 and whose parents graduated from university are more successful in TIMSS exams than others. This study was produced from Alper HANCİ's master thesis that is made consulting Asst. Prof. Gül KALELİ YILMAZ.

  19. Charge It! Translating Electric Vehicle Research Results to Engage 7th and 8th Grade Girls

    NASA Astrophysics Data System (ADS)

    Egbue, Ona; Long, Suzanna; Ng, Ean-Harn

    2015-10-01

    Despite attempts to generate interest in science and technology careers, US students continue to show reduced interest in science, technology, engineering and mathematics (STEM) majors at the collegiate level. If girls are not engaged in STEM learning by the middle school level, studies show that they are even less likely to choose a science- or engineering-related major. This article presents results from a workshop for 7th and 8th grade girls designed to promote knowledge building in the area of sustainability and alternative energy use in transportation and to stimulate greater interest in STEM subjects. The workshop based on research conducted at University X focused on basic concepts of electric vehicles and electric vehicles' batteries. Tests were conducted to evaluate the students' knowledge and perceptions of electric vehicles and to determine the impact of the workshop. Early exposure to meaningful engineering experiences for these young girls may boost interest and the eventual pursuit of engineering and technology education paths.

  7. Neurobehavioral Evaluation System (NES): comparative performance of 2nd-, 4th-, and 8th-grade Czech children.

    PubMed

    Otto, D A; Skalik, I; House, D E; Hudnell, H K

    1996-01-01

    The Neurobehavioral Evaluation System was designed for field studies of workers, but many NES tests can be performed satisfactorily by children as young as 7 or 8 years old and a few tests, such as simple reaction time, can be performed by preschool children. However, little comparative data from children of different ages or grade levels are available. Studies of school children in the Czech Republic indicate that 2nd-grade children could perform the following NES tests satisfactorily: Finger Tapping, Visual Digit Span. Continuous Performance, Symbol-Digit Substitution, Pattern Comparison, and simpler conditions of Switching Attention. Comparative scores of boys and girls from the 2nd, 4th, and 8th grades and power analyses to estimate appropriate sample size were presented. Performance varied systematically with grade level and gender. Larger samples were needed with younger children to achieve comparable levels of statistical power. Gender comparisons indicated that boys responded faster, but made more errors than girls. PMID:8866533

    Paik, Seoung-Hey; Kim, Hyo-Nam; Cho, Boo-Kyoung; Park, Jae-Won

    2004-02-01

    This study investigates the various conceptions held by K-8th Korean grade students regarding the 'changes of state' and the 'conditions for changes of state'. The study used a sample of five kindergarteners, five secondgrade students, five fourth-grade students, five sixth-grade students, and five eighth-grade students. The 25 students attend schools in a rural district of South Korea. Some activities that involved a change in the state of water, including condensation, solidification, and melting, were chosen from K-8th grade science textbooks and attempted by the students. Subsequently, we conducted interviews with the students. While most kindergarteners and second-grade students were able to perceive the phenomena involving changes of state, they were unable to express conceptions related to the changes of state and the conditions under which the state the changes. The upper-grade students, on the other hand, had some conception of the invisible gas state. Most of these students held conceptions about the boiling water's change of state from liquid to gas, but few of them held conceptions about the changes of state involving condensation. Most students understood heat and temperature as conditions of the changes of state, but only applied the heat concept to situations involving rising temperatures. In situations involving cooling, students applied the temperature concept. The younger students understood the concept of heat without understanding the concept of temperature.

    Bagby, Karen; Adams, Susan

    2007-06-01

    Because of the growing obesity epidemic across all age groups in the United States, interventions to increase physical activity and reduce sedentary behaviors have become a priority. Evidence is growing that interventions to increase physical activity and reduce sedentary behaviors have positive results and are generally inexpensive to implement. National and international health organizations are calling for a comprehensive approach for reducing obesity in children that includes increasing physical activity in the school setting. Although the call to increase activity levels in schools is clear, little guidance has been given to schools on specific methods to accomplish this task. This article provides an overview of an evidence-based guideline developed by a physical education teacher and a school nurse to provide inexpensive, easy-to-implement, effective strategies to increase physical activity in students. Tools are also included in the guideline to measure the effectiveness of the intervention. PMID:17536917

  9. Longitudinal Study of Career Cluster Persistence from 8th Grade to 12th Grade with a Focus on the Science, Technology, Engineering, & Math Career Cluster

    NASA Astrophysics Data System (ADS)

    Wagner, Judson

    Today's technology driven global economy has put pressure on the American education system to produce more students who are prepared for careers in Science, Technology, Engineering, and Math (STEM). Adding to this pressure is the demand for a more diverse workforce that can stimulate the development of new ideas and innovation. This in turn requires more female and under represented minority groups to pursue future careers in STEM. Though STEM careers include many of the highest paid professionals, school systems are dealing with exceptionally high numbers of students, especially female and under represented minorities, who begin but do not persist to STEM degree completion. Using the Expectancy-Value Theory (EVT) framework that attributes student motivation to a combination of intrinsic, utility, and attainment values, this study analyzed readily available survey data to gauge students' career related values. These values were indirectly investigated through a longitudinal approach, spanning five years, on the predictive nature of 8 th grade survey-derived recommendations for students to pursue a future in a particular career cluster. Using logistic regression analysis, it was determined that this 8 th grade data, particularly in STEM, provides significantly high probabilities of a 12th grader's average grade, SAT-Math score, the math and science elective courses they take, and most importantly, interest in the same career cluster.

    2001-07-01

    Studies conducted nationwide over the past several decades point consistently to the evidence that American school children lag behind several other countries in science scores. Problems arise from this dilemma, including the question of the ability of our youngsters to compete nationally and globally in the sciences as adults. Current research in this area of scores currently studies mostly mathematics. The few studies conducted concerning science mainly highlight students in other countries and neglects minorities and females regarding outcomes. By contrast, this study investigated the effects of teacher types (also defined as teaching styles or classroom orientation) on student outcomes on two measures; the standardized Standards of Learning 8th grade science test for the state of Virginia, and the Higher-Order Skills test (Berube, 2001), which was a researcher-constricted comprehension measurement. Minority and gender interactions were analyzed as well. Teacher type was designated by using the Constructivist Learning Environment Survey (Taylor & Fraser, 1991). Participants included students from five large urban middle schools and thirteen middle school science teachers. Scores from the two measures were used to determine differences in student outcomes as they pertained to teacher type, gender and ethnicity. Analysis indicated that students who were taught by teachers with more traditional and mixed teaching styles performed better on the Higher-Order Skills comprehension measurement, while teachers with constructivist teaching styles actually had the lowest scoring students. Also, the interaction of ethnicity and teacher type was significant, indicating that Higher-Order Skills scores were influenced by that interaction, with Caucasians scoring the highest when taught by teachers with mixed teaching styles. Such findings could profit school administrators considering the interaction of student achievement and teaching styles on high-stakes testing

    2012-01-01

    Fast food consumption is a dietary factor associated with higher prevalence of childhood obesity in the United States. The association between food prices and consumption of fast food among 5th and 8th graders was examined using individual-level random effects models utilizing consumption data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K), price data from American Chamber of Commerce Researchers Association (ACCRA), and contextual outlet density data from Dun and Bradstreet (D&B). The results found that contextual factors including the price of fast food, median household income, and fast food restaurant outlet densities were significantly associated with fast food consumption patterns among this age group. Overall, a 10% increase in the price of fast food was associated with 5.7% lower frequency of weekly fast food consumption. These results suggest that public health policy pricing instruments such as taxes may be effective in reducing consumption of energy-dense foods and possibly reducing the prevalence of overweight and obesity among US children and young adolescents.

    McCammon, William Gavin Lodge, Jr.

    Teachers should have access to new and innovative tools in order to engage and motivate their students in the classroom. This is especially important as many students view school as an antiquated and dull environment - which they must seemingly suffer through to advance. School need not be a dreaded environment. The use of music as a tool for learning can be employed by any teacher to create an engaging and exciting atmosphere where students actively participate and learn to value their classroom experience. Through this study, a product and process was developed that is now available for any 8th grade science teacher interested in using music to enhance their content. In this study 8th grade students (n=41) in a public school classroom actively interacted with modern songs created to enhance the teaching of chemistry. Data were collected and analyzed in order to determine the effects that the music treatment had on student achievement and motivation, compared to a control group (n=35). Current literature provides a foundation for the benefits for music listening and training, but academic research in the area of using music as a tool for teaching content was noticeably absent. This study identifies a new area of research called "Music-based Teaching" which results in increases in motivation for 8th grade students learning chemistry. The unintended results of the study are additionally significant as the teacher conducting the treatment experienced newfound enthusiasm, passion, and excitement for her profession.

    2014-01-01

    Objectives Understanding the similarities and differences between substance use rates for American Indian (AI) young people and young people nationally can better inform prevention and treatment efforts. We compared substance use rates for a large sample of AI students living on or near reservations for the years 2009–2012 with national prevalence rates from Monitoring the Future (MTF). Methods We identified and sampled schools on or near AI reservations by region; 1,399 students in sampled schools were administered the American Drug and Alcohol Survey. We computed lifetime, annual, and last-month prevalence measures by grade and compared them with MTF results for the same time period. Results Prevalence rates for AI students were significantly higher than national rates for nearly all substances, especially for 8th graders. Rates of marijuana use were very high, with lifetime use higher than 50% for all grade groups. Other findings of interest included higher binge drinking rates and OxyContin® use for AI students. Conclusions The results from this study demonstrate that adolescent substance use is still a major problem among reservation-based AI adolescent students, especially 8th graders, where prevalence rates were sometimes dramatically higher than MTF rates. Given the high rates of substance use-related problems on reservations, such as academic failure, delinquency, violent criminal behavior, suicidality, and alcohol-related mortality, the costs to members of this population and to society will continue to be much too high until a comprehensive understanding of the root causes of substance use are established.

  5. What factors help or hinder the achievement of low SES students? An international comparison using TIMSS 2011 8th grade science data

    NASA Astrophysics Data System (ADS)

    Bruner, Justin L.

    Focusing on science from a cross-country perspective, this study explores the relationship between 8th grade science achievement and student, teacher, and school characteristics. More specifically, this study will pay special attention to low socio-economic status (SES) students and seek to understand why some disadvantaged students are able to have higher than expected achievement in science given their SES while other disadvantaged students are not able to achieve beyond what would be expected given their background. This study will explore the multi-level relationship between the characteristics of students, their teachers, their schools, and student achievement in science. While looking at students in classrooms and in schools, this work will create as precise as possible a measure of student SES by drawing on recommendations of an expert panel commissioned by the National Association of Educational Progress (NAEP) study. The study uses the most recent cycle (2011) of the Trends in International Math and Science Study (TIMSS), to strategically select a six-country sample from the 45 participating countries. This six-country sample was selected by using the country level achievement and the standard deviation of that achievement. This will create a sample that has a range of equality in achievement and strength in achievement. This allows for making comparisons both across and within countries to better understand variations in the factors of student performance, especially for disadvantaged students. This paper builds on the existing research around socio-economic status (SES) and achievement by exploring in more detail the conditions in schools and classrooms around the world that might magnify or reduce the effect of SES on student achievement. The analysis looks at these questions: "What conditions help low SES students achieve higher than what would be expected given their SES?" and "What conditions hinder low SES students to achieve at or below what would

    Danch, J. M.

    2015-12-01

    In 2010 a group of 8th grade geoscience students participated in an extracurricular activity allowing them to conduct original scientific research while being mentored by students enrolled in a 3 - year high school Science Research program. Upon entering high school the mentored students themselves enrolled in the Science Research program and continued for 4 years, culminating with their participation in Science Research 4. This allowed them to continue conducting original scientific research, act as mentors to 8th grade geoscience students and to provide teacher training for both middle and high school teachers conducting inquiry-based science lessons. Of the 7 Science Research 4 students participating since 2010, 100% plan on majoring or minoring in a STEM - related field in college and their individual research projects have been been granted over 70 different awards and honors in science fair and symposia including a 3rd and 4th place category awards at two different international science fairs - the International Sustainable Energy Engineering and Environment Project (iSWEEP) and the International Science and Engineering Fair (ISEF). Science Research 4 students developed and conducted a Society for Science and the Public affiliated science fair for middle school students enrolled in an 8th grade honors geoscience program allowing over 100 students from 5 middle schools to present their research and be judged by STEM professionals. Students with research judged in the top 10% were nominated for participation in the National Broadcom MASTERS program which they successfully entered upon further mentoring from the Science Research 4 students. 8th grade enrollment in the Science Research program for 2015 increased by almost 50% with feedback from students, parents and teachers indicating that the mentorship and participation in the 8th grade science fair were factors in increasing interest in continuing authentic scientific research in high school.

    Although national and state estimates of child obesity are available, data at these levels are insufficient to monitor effects of local obesity prevention initiatives. The purpose of this study was to examine regional changes in the prevalence of obesity due to statewide policies and programs among children in grades 4, 8, and 11 in Texas Health Services Regions (HSRs) between 2000-2002 and 2004-2005, and nine selected counties in 2004-2005. A cross-sectional, probability-based sample of 23,190 Texas students in grades 4, 8, and 11 were weighed and measured to obtain BMI. Obesity was >95th percentile for BMI by age/sex using Centers for Disease Control and Prevention growth charts. Child obesity prevalence significantly decreased between 2000-2002 and 2004-2005 for 4th grade students in the El Paso HSR (-7.0%, P = 0.005). A leveling off in the prevalence of obesity was noted for all other regions for grades 4, 8, and 11. County-level data supported the statistically significant decreases noted in the El Paso region. The reduction of child obesity levels observed in the El Paso area is one of the few examples of effective programs and policies based on a population-wide survey: in this region, a local foundation funded extensive regional implementation of community programs for obesity prevention, including an evidence-based elementary school-based health promotion program, adult nutrition and physical activity programs, and a radio and television advertising campaign. Results emphasize the need for sustained school, community, and policy efforts, and that these efforts can result in decreases in child obesity at the population level. PMID:19798066

    2011-01-01

    Background Violence by young people is one of the most visible forms of violence and contributes greatly to the global burden of premature death, injury and disability. Methods The Global School-based Student Health Survey (GSHS), State of Lara, Venezuela (GSHS-Lara) is a school-based surveillance system. It comprises a repeated, cross-sectional, self-administered survey drawn from a representative sample of 7th to 9th grade students, performed in the school years 2003-2004 (GSHS-Lara 2004) and 2007-2008 (GSHS-Lara 2008). It explores, among other things, a general violence indicator such as school absenteeism due to feeling unsafe at school or on the way to or from school for any reason; and more specific indicators of violence such as robbery, bullying, physical fights and use of weapons, as well as exposure to lectures on how to prevent violence. Results are given in terms of prevalence percentage. Results Absenteeism doubled between the two study periods (10.8% to 20.8%). The number of students that were a victim of robbery remained high and without change both outside (14.2% and 14.8%) and inside school (21.7% and 22.0%). The number of victims of bullying was high and increasing (33.4% and 43.6%). Bullying associated with being physically attacked decreased (18.5% to 14.3%). Physical attacks without active participation and not associated with bullying were frequent (21.5%). Physical fighting with active participation prevalence remained high and without change (27.5% and 28.2%). Carrying a weapon almost doubled (4.3% to 7.1%). Less than 65% reported classes for violence prevention. Conclusions The GSHS-Lara shows that violence is an important public health problem that needs to be addressed by the community and its authorities. PMID:22958602

    The 8th European Antibody Congress (EAC), organized by Terrapin Ltd., was again held in Geneva, Switzerland, following on the tradition established with the 4th EAC. The new agenda format for 2012 included three parallel tracks on: (1) naked antibodies; (2) antibody drug conjugates (ADCs); and (3) bispecific antibodies and alternative scaffolds. The meeting started and closed with three plenary lectures to give common background and to share the final panel discussion and conclusions. The two day event included case studies and networking for nearly 250 delegates who learned of the latest advances and trends in the global development of antibody-based therapeutics. The monoclonal antibody track was focused on understanding the structure-function relationships, optimization of antibody design and developability, and processes that allow better therapeutic candidates to move through the clinic. Discussions on novel target identification and validation were also included. The ADC track was dedicated to evaluation of the ongoing success of the established ADC formats alongside the rise of the next generation drug-conjugates. The bispecific and alternative scaffold track was focused on taking stock of the multitude of bispecific formats being investigated and gaining insight into recent innovations and advancements. Mechanistic understanding, progression into the clinic and the exploration of multispecifics, redirected T cell killing and alternative scaffolds were extensively discussed. In total, nearly 50 speakers provided updates of programs related to antibody research and development on-going in the academic, government and commercial sectors. PMID:23493119

  9. Earth's Dynamic Systems, 8th Edition

    NASA Astrophysics Data System (ADS)

    Winterer, Edward L.

    From the very first edition, Hamblin and Christiansen's elementary geology text, Earth's Dynamic Systems, has stood above its competitors in the quality of its illustrations— all of them now in color. These are exceptionally well planned to bring out essential points of the text and are models of clarity and artistic design, especially the three-dimensional cutaway diagrams of tectonic and geomorphic features. Many new drawings and photos have been incorporated in this 8th edition, including dramatic pictures of planetary surfaces. Each of the 25 chapters begins with an opening statement that puts the chapter in a larger context and closes with a list of key terms, some thought-provoking review questions, a list of suggested readings in more advanced works, and—a novel and useful feature—a list of Web sites germane to the chapter. An illustrated glossary and a useful index complete the book. Pages feature wake-up questions for the student, such as “How do we know that streams erode the valleys through which they flow?”

    Stigler, M H; Perry, C L; Arora, M

    2006-01-01

    Objective To investigate why urban Indian 6th graders may be using more tobacco than urban Indian 8th graders. Design Cross‐sectional survey of students conducted in the summer of 2004, as the baseline evaluation tool for a group‐randomised tobacco prevention intervention trial (Project MYTRI). Mixed‐effects regression models were used to (1) examine the relationship between 15 psychosocial risk factors and current use of any tobacco, by grade; and (2) examine differences in psychosocial risk factors, by grade. Setting Thirty‐two private (high socioeconomic status (SES)) and government (low‐mid SES) schools in two large cities in India (Delhi and Chennai). Subjects Students in the 6th and 8th grade in these schools (n  =  11642). Among these, 50.6% resided in Delhi (v Chennai), 61.4% attended a government school (v a private school), 52.9% were enrolled in 6th grade (v 8th), and 54.9% were male (v female). Main outcome measure Current (past 30 day) use of any tobacco, including chewing tobacco (for example, gutkha), bidis, or cigarettes. Result Almost all psychosocial factors were significantly related to tobacco use, for students in both grades. Some of the strongest correlates included social susceptibility to and social norms about use. Exposure to tobacco advertising was a strong correlate of tobacco use for 6th graders, but not for 8th graders. Sixth graders scored lower than 8th graders on almost all factors, indicating higher risk. Conclusions The “risk profile” of 6th graders suggests they would be vulnerable to use and to begin using tobacco, as well as to outside influences that may encourage use. PMID:16723678

  10. The 8th Century Megadrought Across North America

    NASA Astrophysics Data System (ADS)

    Stahle, D. W.; Therrell, M. D.; Cleaveland, M. K.; Fye, F. K.; Cook, E. R.; Grissino-Mayer, H. D.; Acuna-Soto, R.

    2002-12-01

    Tree-ring data suggest that the 8th and 16th century megadroughts may have been the most severe and sustained droughts to impact North America in the past 1500 years. The 16th century megadrought may have persisted for up to 40 years, and extended from the tropics to the boreal forest and from the Pacific to Atlantic coasts. Evidence for the 8th century drought is sparse, but tree-ring and lake sediment data indicate that this drought extended from the northern Great Plains, across the southwestern United States, and into central Mexico and the Yucatan peninsula. Tree-ring data from Colorado and New Mexico document severe drought from A.D. 735-765, and may provide accurate and precise dating for the onset of the epic droughts reconstructed during the late first millennium A.D. with sedimentary data from Elk Lake, Minnesota; Moon Lake, South Dakota; La Piscina de Yuriria, Guanajuato; and Lake Chichancanab, Yucatan. If these chronological refinements are correct, then the sedimentary records suggest much greater persistence to the 8th century megadrought than indicated by the very high resolution tree-ring data, and a strong second pulse of prolonged drought late in the first millennium. Analyses of instrumental precipitation and drought indices during the 20th century, along with tree-ring reconstructions of climate in Mexico and the Southwest, indicate that annual and decadal droughts can both simultaneously impact the entire region from New Mexico and Texas down into central Mexico. The intensity and large-scale impact of drought across this region seem to be greatest when La Nina conditions and the low phase of the North Pacific oscillation prevail. The tree-ring dated 8th century megadrought occurred near the decline of the Classic Period civilizations at Teotihuacan in central Mexico and in the Mayan region of the Yucatan. The 8th century megadrought may have interacted with anthropogenic environmental degradation, epidemic disease, and social upheaval to

    PubMed

    Brown, William J

    2015-01-01

    This article describes the experiences of Army nurses in the University of Virginia sponsored 8th Evacuation Hospital during World War II. In addition, it examines gender and role differences within the Army Medical Department, and how nurses' contributions helped shape the profession. This research used traditional historical methods of inquiry to include both primary and secondary sources of information. Primary sources include newspaper clippings, letters, citations, and photographs from the archival collections of the 8th Evacuation Hospital located in the University of Virginia Historical Collections and Services, Charlottesville, VA, and journal articles from that period. Secondary sources consisted of bibliographical and historical texts. Evidence suggests that advances in the chain-of-evacuation, antibiotics, dissemination of blood products, and nurses' expanded roles all contributed to increased survival of the wounded. Nurses' performance garnered an enduring respect from combatants who received care, as well as the medical officers and enlisted personnel with whom they worked on a daily basis. Collaboration, mutual respect, and coordinated teamwork were critical for mission success. Army nurses demonstrated that they had the mettle to go into a war zone and perform in an exemplary manner.

  8. Effects of a rise in base level on graded streams

    SciTech Connect

    Dickfoss, P.V. . Geology Dept.)

    1994-04-01

    What changes take place in a longitudinal river profile due to a rise in base level would seem to be a fundamental question in geomorphology, however, little has been accomplished toward answering this question, and the prevailing views are contradictory. Most authors say that a river will adjust its entire profile in response to a rise in base level. This misconception appears to have started in Elmo G. Harris' 1901 article, Effects of Dams and Like Obstructions in Silt-bearing Streams. The hypothesis became popular after publication of J. Hoover Mackin's classic 1948 paper, Concept of the Graded River. In the section Rise of Base Level'' Mackin explained that ''...the only generalization that can be made is that the new profile will be everywhere adjusted to the new prevailing conditions.'' Although Mackin's idea was a conceptual one, the concept has subsequently been taken literally. Contrary to this perception, the small amount of work that has been completed shows rivers will adjust their profiles only a short distance upstream from reservoir level. This may be due to the adjustment becoming infinitesimally small upstream and grading into the original profile so that the adjustment upstream is negligible. Unfortunately the misconception of stream aggradation in response to a rise in base level has prevailed for over 90 years and is widespread in the literature. Many textbooks, both introductory and advanced, from 1971 to the present, and some of the leading names in geomorphology have accepted the misconception without question.

    2008-03-01

    This issue of Journal of Physics: Conference Series contains contributed papers presented at the 8th European Conference on Applied Superconductivity (EUCAS'07) that was held in Brussels, Belgium from 16-20 September 2007. The plenary and invited papers were published in the journal Superconductor Science and Technology. The scientific aims of EUCAS'07 followed the tradition established at the preceding conferences in Göttingen (Germany), Edinburgh (United Kingdom), Eindhoven (The Netherlands), Sitges (Spain), Lyngby (Denmark), Sorrento (Italy) and Vienna (Austria). The focus was placed on the interplay between the most recent developments in superconductor research and the positioning of applications of superconductivity in the marketplace. Although initially founded as an exchange forum mainly for European scientists, it has gradually developed into a truly international meeting with a very significant attendance from the Far East and the United States. Under the guidance of ESAS (the European Society for Applied Superconductivity) this Brussels conference was jointly organized by the University of Ghent and the University of Liege and attracted 795 participants to the scientific programme including a healthy number of 173 students. Participants from 46 countries included a considerable 30% attendance from the Far East and 7% from the United States and Canada. Thirty companies presented their latest developments in the field; 13 plenary and 28 invited lectures highlighted the state-of-the-art in the areas of materials, large-scale as well as small-scale applications were given. Based on a refereed evaluation of all the papers and posters submitted, 347 papers were selected for publication in the IOP electronic journal Journal of Physics: Conference Series and in Superconductor Science and Technology. EUCAS'07 spread a lot of optimism and enthusiasm for this fascinating field of research and for its well established technological potential, especially among the

    2010-04-01

    (The attached PDF contains select pictures from the Amaldi8 Conference) At Amaldi7 in Sydney in 2007 the Gravitational Wave International Committee (GWIC), which oversees the Amaldi meetings, decided to hold the 8th Edoardo Amaldi Conference on Gravitational Waves at Columbia University in the City of New York. With this decision, Amaldi returned to North America after a decade. The previous two years have seen many advances in the field of gravitational wave detection. By the summer of 2009 the km-scale ground based interferometric detectors in the US and Europe were preparing for a second long-term scientific run as a worldwide detector network. The advanced or second generation detectors had well-developed plans and were ready for the production phase or started construction. The European-American space mission, LISA Pathfinder, was progressing towards deployment in the foreseeable future and it is expected to pave the ground towards gravitational wave detection in the milliHertz regime with LISA. Plans were developed for an additional gravitational wave detector in Australia and in Japan (in this case underground) to extend the worldwide network of detectors for the advanced detector era. Japanese colleagues also presented plans for a space mission, DECIGO, that would bridge the gap between the LISA and ground-based interferometer frequency range. Compared to previous Amaldi meetings, Amaldi8 had new elements representing emerging trends in the field. For example, with the inclusion of pulsar timing collaborations to the GWIC, gravitational wave detection using pulsar timing arrays was recognized as one of the prominent directions in the field and was represented at Amaldi8 as a separate session. By 2009, searches for gravitational waves based on external triggers received from electromagnetic observations were already producing significant scientific results and plans existed for pointing telescopes by utilizing gravitational wave trigger events.

  17. Graded safeguards: Determination of attractiveness levels for special nuclear material

    SciTech Connect

    Wilkey, D.D.; Crawford, D.W.

    1994-08-01

    The DOE graded safeguards approach--as described in DOE Order 5633.3A, Control and Accountability of Nuclear Materials, and its guide--requires the determination of category levels of nuclear material locations to establish protection requirements for these locations. A critical parameter related to category determination is knowledge of the attractiveness level of the nuclear material with respect to use in a nuclear explosive device. DOE Order 5633.3A and its guide provide the policy basis for determining the attractiveness level of various forms and types of special nuclear material (SNM); however, these requirements and guidance are necessarily general and sometimes based on arbitrary criteria. Currently, there are large quantities of nuclear material on inventory within the DOE that need attractiveness determinations to ensure appropriate protection controls. Specific forms of these materials include materials in matrices requiring special processing, irradiated SNM that does not meet criteria for self-protecting, low concentration SNM, SNM as numerous small items, and bulk non-portable SNM items. This paper discusses the technical basis for applying material concentration limits for solids and liquids that can influence the various factors and criteria affecting the attractiveness level of SNM. Holdup and rollup considerations for determining category levels will be discussed as well.

  7. Probeware in 8th Grade Science: A Quasi-Experimental Study on Attitude and Achievement

    NASA Astrophysics Data System (ADS)

    Moyer, John F., III

    The use of probeware in the delivery of science instruction has become quite widespread over the past few decades. The current emphasis on Science, Technology, Engineering, and Mathematics (STEM) education, especially in the case of underrepresented populations, seems to have accelerated the inclusion of probeware into curriculum. This quasi-experimental study sought to examine the effects of a direct replacement of traditional science tools with computer-based probeware on student achievement and student attitude toward science. Data analysis was conducted for large comparison groups and then for target STEM groups of African-American, low socioeconomic status, and female. Student achievement was measured by the Energy Concept Inventory and student attitude was measured by the Attitude Toward Science Inventory. The results showed that probeware did not have a significant effect on student achievement for almost all comparison groups. Analysis of student attitude toward science revealed that the use of probeware significantly affected overall student attitude as well as student attitude in several disaggregated subscales of attitude. These findings hold for both the comparison groups and the target STEM groups. Limitations of the study and suggestions for future research are presented.

  4. Grade level and achievement of immigrants’ children: academic redshirting in Hong Kong

    PubMed Central

    2014-01-01

    Data from Hong Kong PISA 2003 show that 15-year-old Hong Kong students who have immigrant parents from mainland China are grossly overrepresented in grades below the modal grade attended by most native Hong Kong students. Same-age comparison, when grade level is not taken into account, puts immigrants’ children at a disadvantaged position in the mathematics, reading, and science literacy tests. The academic advantage of immigrants’ children in Hong Kong is only revealed after grade is statistically controlled. Also, mainland immigrant students who are repeaters outperform native Hong Kong repeaters. Immigrant redshirting is a possible driving force behind these results. PMID:25214810

    Heath, Bruce E.; Crier, tomyka

    2003-01-01

    With the advancements in the computing power of personal computers, pc-based flight simulators and trainers have opened new avenues in the training of airplane pilots. It may be desirable to have the flight simulator make a quantitative evaluation of the progress of a pilot's training thereby reducing the physical requirement of the flight instructor who must, in turn, watch every flight. In an experiment, University students conducted six different flights, each consisting of two level turns. The flights were three minutes in duration. By evaluating videotapes, two certified flight instructors provided separate letter grades for each turn. These level turns were also evaluated using two other computer based grading methods. One method determined automated grades based on prescribed tolerances in bank angle, airspeed and altitude. The other method used was deviations in altitude and bank angle for performance index and performance grades.

    Sadeghi, Nader; Czarnetzki, Uwe

    2010-03-01

    The 8th Workshop on Frontiers in Low Temperature Plasma Diagnostics (FLTPD) was held in Blansko, near Brno, Czech Republic. FLTPD is a biennial European event in which scientists working on low temperature plasmas present their recent results, pointing out in particular the originality of the diagnostic techniques used. The idea of starting this series of workshops was born out of a discussion between Frieder Döbele, Bill Graham and one of us when travelling together from Bar Harbor, USA (after the 6th LAPD) to Montreal, Canada, in October 1993. It became evident that we had been lacking a European meeting that could bring together experts in the field of low temperature plasma diagnostics and facilitate sharing the knowledge of these diagnostics with a new generation of scientists. The first FLTPD was held in Les Houches, France, in February 1995. Since then it has been held in the spring of every other year in different European countries, as shown below. The next meeting will be held in Zinnowitz, near Greifswald, Germany, in May 2011.

  6. Factors in seventh grade academics associated with performance levels on the tenth grade biology end of course test in selected middle and high schools in northwest Georgia

    NASA Astrophysics Data System (ADS)

    Ward, Jennifer Henry

    This study attempted to identify factors in seventh grade academics that are associated with overall success in tenth grade biology. The study addressed the following research questions: Are there significant differences in performance levels in seventh grade Criterion Referenced Competency Test (CRCT) scores in science, math, reading, and language arts associated with performance categories in tenth grade biology End of Course Test (EOCT) and the following demographic variables : gender, ethnicity, socioeconomic status, disability category, and English language proficiency level? Is there a relationship among the categorical variables on the tenth grade biology EOCT and the same five demographic variables? Retrospective causal comparative research was used on a representative sample from the middle schools in three North Georgia counties who took the four CRCTs in the 2006-2007 school year, and took the biology EOCT in the 2009-2010 school year. Chi square was used to determine the relationships of the various demographic variables on three biology EOCT performance categories. Twoway ANOVA determined relationships between the seventh grade CRCT scores of students in the various demographic groups and their performance levels on the biology EOCT. Students' performance levels on the biology EOCT matched their performance levels on the seventh grade CRCTs consistently. Females performed better than males on all seventh grade CRCTs. Black and Hispanic students did worse than White and Asian/Asian Indian students on the math CRCT. Students living in poverty did worse on reading and language arts CRCTs than students who were better off. Special education students did worse on science, reading, and language arts CRCTs than students not receiving special education services. English language learners did worse than native English speakers on all seventh grade CRCTs. These findings suggest that remedial measures may be taken in the seventh grade that could impact

    2015-01-01

    Background: Acute cholecystitis is the most common complication of gallbladder stones. Today, Tokyo guidelines criteria are recommended for diagnosis, grading, and management of acute cholecystitis. Objectives: We aimed to evaluate the levels of C-reactive protein (CRP) at different cut-off values to predict the severity of the disease and its possible role in grading the disease with regard to the guideline. Patients and Methods: This is a retrospective study, analyzing 682 cases out of consecutive 892 patients with acute cholecystitis admitted to two different general surgery clinics in Istanbul, Turkey. Records of patients diagnosed with acute cholecystitis were screened retrospectively from the hospital computer database between January 2011 and July 2014. A total of 210 patients with concomitant diseases causing high CRP levels were excluded from the study. The criteria of Tokyo guidelines were used in grading the severity of acute cholecystitis, and patients were divided into 3 groups. CRP values at the time of admission were analyzed and compared among the groups. Results: Mean CRP levels of groups were found to be significantly different, 18.96 mg/L in Group I, 133.51 mg/L in Group II, and 237.23 mg/L in Group III (P < 0.001). Having examined CRP values among the groups, they were found to be highly and significantly correlated with the disease grade (P < 0.0001). After evaluating CRP levels according to the grade of the disease, group 2 was distinguished from group 1 with a cut-off CRP level of 70.65 mg/L, and from group 3 with a value of 198.95 mg/L. Those results were found to be statistically significant (P < 0.001). Conclusions: CRP, a well-known acute phase reactant that increases rapidly in various inflammatory processes, can be accepted as a strong predictor in classifying different grades of the disease, and treatment can be reliably planned according to this classification.

    2014-04-01

    Enactment of scientific inquiry in classroom has attracted a great attention of science educators around the world. In this study, we examined two competent teachers' (one Grade 9 chemistry teacher and one Grade 4 science teacher) enactment of scientific inquiry in selected teaching units to reveal the characteristics of enacted inquiry at different grade levels by analyzing lesson sequence videos. The coding schemes for enacted inquiry consist of ontological properties and instructional practices. Pre-topic and post-topic teacher interviews and the two teachers' responses to a questionnaire were adopted to identify the factors influencing teacher's enactment. The results indicate that the two case teachers' enactment involved a range of inquiry activities. The enacted inquiry at fourth-grade level covered all the inquiry elements, tending to engage students in the whole procedure of inquiry. The ninth-grade chemistry class placed emphasis on the elements "making plans" to solve problems in authentic context. Important factors influencing the enactment include teacher's understanding about scientific inquiry, textbooks, assessment, students and resource. Implications for inquiry enactment and instruction improvement have been provided.

    2009-09-01

    These proceedings arose from the 8th Asian International Seminar on Atomic and Molecular Physics (AISAMP) which was held at the University of Western Australia 24-28 November 2008. The history of AISAMP (Takayanagi and Matsuzawa 2002) recognizes its origin from the Japan-China meeting of 1985, and the first use of the name 'The First Asian International Seminar on Atomic and Molecular Physics (AISAMP)' in 1992. The initial attendees, Japan and China, were joined subsequently by scientists from Korea, Taiwan, India, Australia and recently by Malaysia, Thailand, Vietnam, Turkey Iran, UK and USA. The main purpose of the biennial AISAMP series is to create a wide forum for exchanging ideas and information among atomic and molecular scientists and to promote international collaboration. The scope of the AISAMP8 meeting included pure, strategic and applied research involving atomic and molecular structure and processes in all forms of matter and antimatter. For 2008 the AISAMP conference incorporated the Australian Atomic and Molecular Physics and Quantum Chemistry meeting. The topics for AISAMP8 embraced themes from earlier AISAMP meetings and reflected new interests, in atomic and molecular structures, spectroscopy and collisions; atomic and molecular physics with laser or synchrotron radiation; quantum information processing using atoms and molecules; atoms and molecules in surface physics, nanotechnology, biophysics, atmospheric physics and other interdisciplinary studies. The implementation of the AISAMP themes, as well as the international representation of research interests, is indicated both in the contents list of these published manuscripts as well as in the program for the meeting. Altogether, 184 presentations were made at the 8th AISAMP, including Invited Talks and Contributed Poster Presentations, of which 60 appear in the present Proceedings after review by expert referees in accordance with the usual practice of Journal of Physics: Conference Series of

    The present study was conducted to evaluate the level of food safety protection provided to consumers of Grade "A" milk and milk products in the United States by the National Conference on Interstate Milk Shipments (NCIMS) Grade "A" Milk Safety Program through its implementation and enforcement of the U.S. Grade "A" Pasteurized Milk Ordinance (PMO). The number of reported illnesses associated with Grade "A" milk and milk products in the United States was obtained from state and federal agencies and published articles. The consumption of Grade "A" milk and milk products in the United States was estimated from food consumption survey data for individuals. The level of food safety protection was measured quantitatively using the metric of annual illness attack rate. During a 15-year period (1999 through 2013), the estimated annual illness attack rate was 0.41 reported illnesses per 1 billion exposures (estimated using person-day intake data) or 0.52 reported illnesses per 1 billion lb (454 million kg) of Grade "A" milk and milk products consumed. Food safety protection provided to consumers of Grade "A" milk and milk products by the NCIMS through its implementation and enforcement of the PMO is important given the common consumption of Grade "A" milk and milk products in the United States.

    Purpose In addition to excess adiposity, low cardiorespiratory fitness (CRF) and low musculoskeletal fitness (MSF) are important independent risk factors for future cardio-metabolic disease in adolescents, yet global fitness surveillance in adolescents is poor. The objective of this study was to describe and investigate geographical variation in levels of health-related physical fitness, including CRF, MSF, body mass index (BMI), and waist circumference (WC) in Chilean 8th graders. Methods This cross-sectional study was based on a population-based, representative sample of 19,929 8th graders (median age = 14 years) in the 2011 National Physical Education Survey from Chile. CRF was assessed with the 20-meter shuttle run test, MSF with standing broad jump, and body composition with BMI and WC. Data were classified according to health-related standards. Prevalence of levels of health-related physical fitness was mapped for each of the four variables, and geographical variation was explored at the country level by region and in the Santiago Metropolitan Area by municipality. Results Girls had significantly higher prevalence of unhealthy CRF, MSF, and BMI than boys (p<0.05). Overall, 26% of boys and 55% of girls had unhealthy CRF, 29% of boys and 35% of girls had unhealthy MSF, 29% of boys and 44% of girls had unhealthy BMI, and 31% of adolescents had unhealthy WC. High prevalence of unhealthy fitness levels concentrates in the northern and middle regions of the country and in the North and Southwest sectors for the Santiago Metropolitan Area. Conclusion Prevalence of unhealthy CRF, MSF, and BMI is relatively high among Chilean 8th graders, especially in girls, when compared with global estimates. Identification of geographical regions and municipalities with high prevalence of unhealthy physical fitness presents opportunity for targeted intervention. PMID:25255442

    Connectivity in a gene-gene network declines with age, typically within gene clusters. We explored the effect of short-term (3 months) graded calorie restriction (CR) (up to 40 %) on network structure of aging-associated genes in the murine hypothalamus by using conditional mutual information. The networks showed a topological rearrangement when exposed to graded CR with a higher relative within cluster connectivity at 40CR. We observed changes in gene centrality concordant with changes in CR level, with Ppargc1a, and Ppt1 having increased centrality and Etfdh, Traf3 and Abcc1 decreased centrality as CR increased. This change in gene centrality in a graded manner with CR, occurred in the absence of parallel changes in gene expression levels. This study emphasizes the importance of augmenting traditional differential gene expression analyses to better understand structural changes in the transcriptome. Overall our results suggested that CR induced changes in centrality of biological relevant genes that play an important role in preventing the age-associated loss of network integrity irrespective of their gene expression levels.

    The 8th European Antibody Congress (EAC), organized by Terrapin Ltd., was again held in Geneva, Switzerland, following on the tradition established with the 4th EAC. The new agenda format for 2012 included three parallel tracks on: (1) naked antibodies; (2) antibody drug conjugates (ADCs); and (3) bispecific antibodies and alternative scaffolds. The meeting started and closed with three plenary lectures to give common background and to share the final panel discussion and conclusions. The two day event included case studies and networking for nearly 250 delegates who learned of the latest advances and trends in the global development of antibody-based therapeutics. The monoclonal antibody track was focused on understanding the structure-function relationships, optimization of antibody design and developability, and processes that allow better therapeutic candidates to move through the clinic. Discussions on novel target identification and validation were also included. The ADC track was dedicated to evaluation of the ongoing success of the established ADC formats alongside the rise of the next generation drug-conjugates. The bispecific and alternative scaffold track was focused on taking stock of the multitude of bispecific formats being investigated and gaining insight into recent innovations and advancements. Mechanistic understanding, progression into the clinic and the exploration of multispecifics, redirected T cell killing and alternative scaffolds were extensively discussed. In total, nearly 50 speakers provided updates of programs related to antibody research and development on-going in the academic, government and commercial sectors. PMID:23493119

    Cheung, Derek

    2009-01-01

    The purpose of this quantitative study was to examine the interaction effect between grade level and gender with respect to students' attitudes toward chemistry lessons taught in secondary schools. The sample consisted of 954 chemistry students in grades Secondary 4-7 (approximately 16-19 years of age) in Hong Kong. Students' attitudes were surveyed using an attitude toward chemistry lessons scale (ATCLS), and subscale scores were produced on four dimensions: liking for chemistry theory lessons; liking for chemistry laboratory work; evaluative beliefs about school chemistry; and behavioral tendencies to learn chemistry. When the ATCLS data were subjected to two-way MANOVA, the interaction effect between grade level and gender on students' attitudes toward chemistry lessons was statistically significant. The interaction effect was attributable to scores on the theory lessons subscale and laboratory work subscale. Male students in Secondary 4 and 5 liked chemistry theory lessons more than their female counterparts. However, male students' liking for chemistry laboratory work declined when they progressed from Secondary 4 to Secondary 7; no such a significant decline in attitude toward chemistry laboratory work was found in females. Overall, both males and females were just marginally positive about chemistry lessons during the years of secondary schooling. Implications of these findings for curriculum design are discussed.

    Roberts, Patrice Helen

    This research was designed to determine the relationships among students' achievement scores on grade-level science content, on science content that was three years above-grade level, on attitudes toward instructional approaches, and learning-styles perceptual preferences when instructional approaches were multisensory versus traditional. The dependent variables for this investigation were scores on achievement posttests and scores on the attitude survey. The independent variables were the instructional strategy and students' perceptual preferences. The sample consisted of 74 educationally oriented seventh-grade students. The Learning Styles Inventory (LSI) (Dunn, Dunn, & Price, 1990) was administered to determine perceptual preferences. The control group was taught seventh-grade and tenth-grade science units using a traditional approach and the experimental group was instructed on the same units using multisensory instructional resources. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. The traditional unit included oral reading from the textbook, completing outlines, labeling diagrams, and correcting the outlines and diagrams as a class. The multisensory unit included five instructional stations established in different sections of the classroom to allow students to learn by: (a) manipulating Flip Chutes, (b) using Electroboards, (c) assembling Task Cards, (d) playing a kinesthetic Floor Game, and (e) reading an individual Programmed Learning Sequence. Audio tapes and scripts were provided at each location. Students circulated in groups of four from station to station. The data subjected to statistical analyses supported the use of a multisensory, rather than a traditional approach, for teaching science content that is above-grade level. T-tests revealed a positive and significant impact on achievement scores (p < 0.0007). No significance was detected on grade-level achievement nor on the perceptual

  1. Expression of Telomeres in Astrocytoma WHO Grade 2 to 4: TERRA Level Correlates with Telomere Length, Telomerase Activity, and Advanced Clinical Grade12

    Cancer cells bypass replicative senescence, the major barrier to tumor progression, by using telomerase or alternative lengthening of telomeres (ALT) as telomere maintenance mechanisms (TMMs). Correlation between ALT and patient survival was demonstrated for high-grade astrocytomas. Transcription from subtelomeres produces telomeric repeat-containing RNA (TERRA), a natural inhibitor of telomerase activity (TA). This led us to evaluate correlations of TERRA and TMM with tumor grade and outcome in astrocytoma patients. SYBR Green real-time reverse transcription-polymerase chain reaction assays for quantitation of total and chromosome 2p and 18p specific TERRA levels were developed. Tumor samples from 46 patients with astrocytoma grade 2 to 4, tissue controls, and cell lines were assessed. TMMs were evaluated by measuring TA and by detecting long telomeres due to ALT. In glioblastoma multiforme (GBM) grade 4, total TERRA levels were similar to cell lines but 14-, 31-, and 313-fold lower compared with grade 3, grade 2, and nonmalignant tissue, respectively. Total TERRA levels differed from chromosomal levels. Low 2p TERRA levels correlated with dense promoter methylation of subtelomeric CpG islands, indicating that TERRA expression in gliomas may be chromosome specific and epigenetically regulated. Total TERRA levels correlated with diagnosis, with low or absent TA and the presence of ALT, and were tentatively associated with favorable patient prognosis in our cohort (P = .06). TA and short telomeres identified a subset of GBM with a median survival of only 14.8 months. TERRA and TA may be prognostic in astrocytic tumors. PMID:22348177

    In this article, we introduce ESCOLEX, the first European Portuguese children's lexical database with grade-level-adjusted word frequency statistics. Computed from a 3.2-million-word corpus, ESCOLEX provides 48,381 word forms extracted from 171 elementary and middle school textbooks for 6- to 11-year-old children attending the first six grades in the Portuguese educational system. Like other children's grade-level databases (e.g., Carroll, Davies, & Richman, 1971; Corral, Ferrero, & Goikoetxea, Behavior Research Methods, 41, 1009-1017, 2009; Lété, Sprenger-Charolles, & Colé, Behavior Research Methods, Instruments, & Computers, 36, 156-166, 2004; Zeno, Ivens, Millard, Duvvuri, 1995), ESCOLEX provides four frequency indices for each grade: overall word frequency (F), index of dispersion across the selected textbooks (D), estimated frequency per million words (U), and standard frequency index (SFI). It also provides a new measure, contextual diversity (CD). In addition, the number of letters in the word and its part(s) of speech, number of syllables, syllable structure, and adult frequencies taken from P-PAL (a European Portuguese corpus-based lexical database; Soares, Comesaña, Iriarte, Almeida, Simões, Costa, …, Machado, 2010; Soares, Iriarte, Almeida, Simões, Costa, França, …, Comesaña, in press) are provided. ESCOLEX will be a useful tool both for researchers interested in language processing and development and for professionals in need of verbal materials adjusted to children's developmental stages.

    An experiment was conducted to determine melamine residual levels in the tissues of broiler chickens fed diets containing graded levels of melamine. Ten experimental diets were developed to contain 0, 2, 5, 10, 20, 50, 100, 200, 500, and 1,000 mg of melamine/kg of diet. Each diet was offered in 4 replicate cages (12 birds per cage) from d 1 to 42, followed by a 7-d feeding of a withdrawal diet that contained no melamine. On d 28, 42, and 49, one bird per replicate was killed and tissue samples from the breast meat, liver, and kidney were collected for the determination of residual melamine levels. Throughout the 42-d feeding period, feeding diets containing graded levels of melamine had no effect (P>0.05) on the weight gain, feed intake, feed conversion ratio, and mortality of broiler chickens. Residue levels of melamine in broiler tissues at d 28 and 42 were below the detection limit when the diets containedlevels increased (P<0.05) with the increasing levels of melamine in birds fed diets containing higher than 100 mg/kg. At d 42, a similar trend was observed in the kidney, but melamine was detected in breast meat and liver only in birds fed diets containing 500 and 1,000 mg of melamine/kg of diet. Melamine distribution varied (P<0.05) in different tissues, with the highest concentration in the kidney. A withdrawal period of 7 d was found to clear the tissues of melamine. PMID:19762871

    Barnes, J. Aaron

    2015-01-01

    Background: Patient education is one of the key components required for patients to participate in decision making for their care. Sources of information should be complete and understandable. The objective of this study was to assess the quality and reading grade level of freely available materials pertaining to the evaluation and treatment of thyroid nodules. Methods: All available materials were gathered through a comprehensive Internet search or direct contact with each identified organization associated with thyroid care. Materials meeting inclusion criteria were assessed for completeness of content and reading grade level using the SMOG readability formula. Then, the DISCERN instrument was utilized to assess the quality of the five materials which had the best (lowest) and the five materials that had the worst (highest) SMOG reading grade levels. Results: A total of 63 materials on thyroid nodule evaluation and management were identified. A minority of materials presented readers with a complete picture of the topic, describing both benefits and cautions of thyroid nodule evaluation, benefits and cautions of fine-needle thyroid nodule biopsy, or risks, benefits, and long-term effects of thyroidectomy. The SMOG reading grade level assessment was well above recommended levels. The range was eighth grade to college level; the mean and median reading grade level were 13. Lastly, the DISCERN instrument revealed that most of the materials with both the best and the worst reading grade levels assessed had “extensive or serious shortcomings” that would impede their usefulness as high-quality sources of information regarding management options. Conclusions: Existing thyroid nodule evaluation and management materials have serious shortcomings. Future work should focus on the development of patient materials that are both grade level appropriate and meet the DISCERN criteria for topic completeness and accuracy. PMID:25384093

    Objective Physical activity improves function for adults with arthritis, but it is unknown if there is a graded relationship with functional benefit. We examine the cross-sectional and longitudinal relationship between self-reported physical activity and observed functional performance in adults with knee osteoarthritis. Methods The Osteoarthritis Initiative cohort included 2589 persons with knee osteoarthritis (2301 having longitudinal follow-up) aged 45 to 79 years at baseline. Two years of prospective annual functional performance was assessed from timed 20 meter walk tests. We used linear regression to estimate differences across physical activity quartiles in subsequent function (baseline and 1-year activity predicts 1- and 2-year function, respectively) adjusted for demographics (age, gender, race/ethnicity, education, marital status) and health factors (osteoarthritis severity, knee symptoms, knee pain, knee injury, body mass index, comorbidity, depression, smoking, alcohol use, other joint pain). Results Increasing physical activity levels had a significant graded relationship with functional performance. Adults in physical activity quartile groups, from least to most active, had average gait speed of 4.0, 4.2, 4.3, 4.5 feet/second respectively at baseline (p-value for trend <.001) and 4.1, 4.2, 4.3, 4.5 feet/second after one year (p-value for trend <.001); increasing trends remained significant after adjusting for covariates. Findings were similar within gender and age groups. Conclusion These prospective data showed a consistent graded relationship between physical activity level and better performance in adults with knee osteoarthritis. These findings support guidelines that encourage persons with arthritis who cannot attain minimum recommended physical activity to be as active as possible. PMID:20862681

    2009-06-09

    In today's world, the use of parallel programming and architectures is essential for simulating practical problems in engineering and related disciplines. Significant progress in CPU architecture (multi- and many-core CPUs, SMT, transactional memory, virtualization support, shared caches etc.) system scalability, and interconnect technology, continues to provide new opportunities, as well as new challenges for both system architects and software developers. These trends are paralleled by progress in algorithms, simulation techniques, and software integration from multiple disciplines. In its 8th year, ParSim continues to build a bridge between application disciplines and computer science and to help fostering closer cooperations between these fields. Since its successful introduction in 2002, ParSim has established itself as an integral part of the EuroPVM/MPI conference series. In contrast to traditional conferences, emphasis is put on the presentation of up-to-date results with a short turn-around time. We believe that this offers a unique opportunity to present new aspects in this dynamic field and discuss them with a wide, interdisciplinary audience. The EuroPVM/MPI conference series, as one of the prime events in parallel computation, serves as an ideal surrounding for ParSim. This combination enables participants to present and discuss their work within the scope of both the session and the host conference. This year, five papers from authors in five countries were submitted to Par-Sim, and we selected three of them. They cover a range of different application fields including mechanical engineering, material science, and structural engineering simulations. We are confident that this resulted in an attractive special session and that this will be an informal setting for lively discussions as well as for fostering new collaborations. Several people contributed to this event. Thanks go to Jack Dongarra, the EuroPVM/MPI general chair, and to Jan Westerholm, Juha

    2005-06-01

    The 8th International Conference on Strangeness in Quark Matter (SQM2004) was held at at the Breakwater Lodge, which is part of the Graduate School of Business of the University of Cape Town. The architecture of the Breakwater Lodge is a stark reminder of the fact that its original purpose was to serve as a municipal jail. It appears that the spectacular background of Table Mountain and the V&A Waterfront and an excellent set of speakers were sufficient to keep the lecture rooms full to capacity, despite the numerous temptations of Cape Town. This is the first time a major heavy ion conference has been held in South Africa, and the timing is fortuitous, with a long-delayed MoU between South Africa and CERN at last being signed and finalized. At last, funding is being made available for South African scientists to play a meaningful role and make contributions to the international effort in heavy ion physics. Despite the substantial distance from the major cities in the northern hemisphere, the conference was very well attended and the number of participants was about 50% larger than originally anticipated. Participants came from China, India, Japan, the United States, Brazil and many European countries. We would like to thank all of the SQM2004 participants for their efforts and, in particlular, all of the plenary and parallel speakers for their hard work in making this conference such a success. Of course, even more thanks go to all the chairpersons of the various sessions who struggled to keep the conference program on the (admittedly tight) schedule. For future conferences, we recommend keeping a bell handy! Photograph Participants gather on the UCT campus with Table Mountain in the backgound. We would like to thank Professor Tony Fairall for a most entertaining after-dinner talk about all that is unusual and fascinating about the southern hemisphere. It could not be emphasized enough that the daily working of the meeting would have ground to a halt without the

    2015-01-01

    Objective The intensive nature of a 5- or 6-week teaching block poses unique problems for adequate delivery of content. This study was designed to compare the delivery of a unit of undergraduate neuroanatomy in a short summer school period, as a traditionally taught unit, with a rendition given in the form of the “Flipped Classroom.” The aim was to evaluate the effectiveness of the flipped classroom in the intensive mode classroom. Methods The flipped classroom encompassed the same learning outcomes, but students were responsible for covering the content at home in preparation for tutorials that applied their acquired knowledge to higher levels of thinking. The main outcome measures were the final course grades and the level of satisfaction with the course. Results There were no significant differences between the 2 cohorts in final grades (p = .259), self-rated knowledge (p = .182), or overall satisfaction with the course (p = .892). Conclusion This particular design of the flipped classroom did not add value to the intensive mode experience. It may be that this mode of delivery is ill suited to intensive classes for subjects that carry a lot of content. The use of the flipped classroom requires further research to fully evaluate its value. PMID:25902472

    NASA Astrophysics Data System (ADS)

    2014-06-01

    The 8th International Conference on Fine Particle Magnetism (ICFPM) was held in Perpignan from 24 to 27 June 2013, and was the continuation of the previous meetings held in Bangor (1996), Rome (1991), Barcelona (1999), Pittsburg (2002), London (2004), Rome (2007) and Uppsala (2010). The next meeting will be organized by Profs. Robert D. Shull, George Hadjipanayis and Cindi Dennis, in 2016 at NIST, Gaithersburg (USA). ICFPM is a small-sized conference focused on the magnetism of nanoparticles. It provides an international forum for discussing the state-of-the-art understanding of physics of these systems, of their properties and the underlying phenomena, as approached from a variety of directions: theory and modelling, experiments on well characterized or model systems (both fabricated and synthetised), as well as experiments on technologically-relevant non-ideal systems. This meeting brought together about 120 participants working on experimental, theoretical and applied topics of the multidisciplinary research areas covered by magnetic nanoparticles, with focused interest on either single-particle or collective phenomena. The technical program of the conference was based on keynote conferences, invited talks, oral contributions and poster sessions, covering the following aspects: . Fabrication, synthesis, characterization . Single particle, surface and finite-size effects on magnetic properties . Magnetization dynamics, micro-wave assisted switching, dynamical coupling . Assemblies, collective effects, self-assembling and nanostructuring . Applications : hyperthermia, drug delivery, magneto-caloric, magneto-resistance, magneto-plasmonics, magnetic particle imaging This ICFPM edition was organized by the group Nanoscale Spin Systems of the laboratory PROMES of the CNRS (UPR8521), and Université de Perpignan Via Domitia. The meeting took place at the Congress Center of the city of Perpignan providing high-quality facilities for the technical program as well for the

    Frändberg, Birgitta; Lincoln, Per; Wallin, Anita

    2013-12-01

    Explanations involving submicro levels of representation are central to science education, but known to be difficult for students in secondary school. This study examines students' written explanations of physical and chemical phenomena regarding matter and changes in matter, in a large-scale test. This is done in order to understand linguistic challenges in constructing submicro level explanations involving the particle model of matter. Drawing from systemic functional linguistics, the lexicogrammatics used in explanations for realising experiential meaning in student explanations were analysed. We used answers to two partly constructed response items from the Swedish part of Trends in International Mathematics and Science Studies 2007, grade 8, to sort out explanations referring to the particle model of matter. These answers (86 from 954) were analysed regarding choices of vocabulary and grammar to distinguish between macro and submicro level of representation. The results show that students use a wide variety of lexicogrammatical resources to realise what happens on both macro and submicro level of representation, with greater diversity of verbs on the submicro level of explanation. The results suggest an uncertainty about the distinction between macro and submicro level of explanation.

    Olsson, Lars E.; Bäck, S.; Ceberg, Sofie

    2015-01-01

    IC3DDose 2014, the 8th International Conference on 3D Radiation Dosimetry was held in Ystad, Sweden, from 4-7 September 2014. This grew out of the DosGel series, which began as DosGel99, the 1st International Workshop on Radiation Therapy Gel Dosimetry in Lexington, Kentucky. Since 1999 subsequent DoSGel conferences were held in Brisbane, Australia (2001), Ghent, Belgium (2004), Sherbrooke, Canada (2006) and Crete, Greece (2008). In 2010 the conference was held on Hilton Head Island, South Carolina and underwent a name-change to IC3DDose. The 7th and last meeting was held in Sydney, Australia from 4-8 November 2012. It is worth remembering that the conference series started at the very beginning of the intensity modulated radiotherapy era and that the dosimeters being developed then were, to some extent, ahead of the clinical need of radiotherapy. However, since then the technical developments in radiation therapy have been dramatic, with dynamic treatments, including tracking, gating and volumetric modulated arc therapy, widely introduced in the clinic with the need for 3D dosimetry thus endless. This was also reflected by the contributions at the meeting in Ystad. Accordingly the scope of the meeting has also broadened to IC3DDOSE - I See Three-Dimensional Dose. A multitude of dosimetry techniques and radiation detectors are now represented, all with the common denominator: three-dimensional or 3D. Additionally, quality assurance (QA) procedures and other aspects of clinical dosimetry are represented. The implementation of new dosimetric techniques in radiotherapy is a process that needs every kind of caution, carefulness and thorough validation. Therefore, the clinical needs, reformulated as the aims for IC3DDOSE - I See Three-Dimensional Dose, are: • Enhance the quality and accuracy of radiation therapy treatments through improved clinical dosimetry. • Investigate and understand the dosimetric challenges of modern radiation treatment techniques. • Provide

The next meeting will be organized by Profs. Robert D. Shull, George Hadjipanayis and Cindi Dennis, in 2016 at NIST, Gaithersburg (USA). ICFPM is a small-sized conference focused on the magnetism of nanoparticles. It provides an international forum for discussing the state-of-the-art understanding of physics of these systems, of their properties and the underlying phenomena, as approached from a variety of directions: theory and modelling, experiments on well characterized or model systems (both fabricated and synthetised), as well as experiments on technologically-relevant non-ideal systems. This meeting brought together about 120 participants working on experimental, theoretical and applied topics of the multidisciplinary research areas covered by magnetic nanoparticles, with focused interest on either single-particle or collective phenomena. The technical program of the conference was based on keynote conferences, invited talks, oral contributions and poster sessions, covering the following aspects: . Fabrication, synthesis, characterization . Single particle, surface and finite-size effects on magnetic properties . Magnetization dynamics, micro-wave assisted switching, dynamical coupling . Assemblies, collective effects, self-assembling and nanostructuring . Applications : hyperthermia, drug delivery, magneto-caloric, magneto-resistance, magneto-plasmonics, magnetic particle imaging This ICFPM edition was organized by the group Nanoscale Spin Systems of the laboratory PROMES of the CNRS (UPR8521), and Université de Perpignan Via Domitia. The meeting took place at the Congress Center of the city of Perpignan providing high-quality facilities for the technical program as well for the

    Integrative education is being implemented by classroom teachers who want to immerse students in an environment rich in problem-solving skills, critical analysis skills, ethics, valuing of knowledge, and communication of learning. Several subject areas in the curriculum have been integrated, such as literature with social studies and mathematics with science. The focus of this dissertation is on the integration of science and social studies at the fifth grade level using the Mississippi State Department of Education Curriculum Guidelines and Objectives (MSDE, 1995) and the National Science Education Standards (National Research Council (NRC), 1996). An instructional package of lesson plans that teachers can use as ideas to create their own plans for an integrated curriculum of science and social studies was devised. The Mississippi State Department of Education Curriculum Guidelines and Objectives for Social Studies (MSDE, 1995) at the fifth grade level contain fifteen competencies. Three standards from the National Science Education Standards (NRC, 1996) were chosen. They include (a) science and technology, (b) science in personal and social perspectives, and (c) the history and nature of science. Each competency for social studies has three lesson plans written that integrate the three chosen standards from the National Science Education Standards. A total of forty-five lesson plans were written integrating science and social studies. Each lesson plan includes an objective, materials, procedures, and evaluation for teachers. Teachers are encouraged to use the lesson plans as a guide in creating their own lesson plans that would correspond to their school's particular curriculum guidelines. Consideration should be given to the learning levels and styles of their classroom. This qualitative study was done to create lesson plans that integrate science and social studies with the hope that teachers will expand upon them and implement them into their curricula.

    The canonical Wnt signaling pathway plays a major role in the regulation of embryogenesis and organogenesis, where signal strength-dependent cellular responses are of particular importance. To assess Wnt signal levels in individual cells, and to circumvent the integration site-dependent bias shown in previous Wnt reporter lines, we constructed a new Wnt signal reporter mouse line R26-WntVis. Heptameric TCF/LEF1 binding sequences were combined with a viral minimal promoter to confer a graded response to the reporter depending on Wnt signal strengths. The histone H2B-EGFP fusion protein was chosen as the fluorescent reporter to facilitate single-cell resolution analyses. This WntVis reporter gene was then inserted into the ROSA26 locus in an orientation opposite to that of the endogenous gene. The R26-WntVis allele was introduced into Wnt3a(-/-) and Wnt3a(vt/-) mutant mouse embryos and compared with wild-type embryos to assess its performance. The R26-WntVis reporter was activated in known Wnt-dependent tissues and responded in a graded fashion to signal intensity. This analysis also indicated that the major Wnt activity early in embryogenesis switched from Wnt3 to Wnt3a around E7.5. The R26-WntVis mouse line will be widely useful for the study of Wnt signal-dependent processes. PMID:27030109

    Mountain endurance running has increased in popularity in recent years. Thus the aim of the present study was to determine if maximal oxygen uptake (VO2max) and energy cost of running (Cr) measured during level and uphill running are associated. Ten high level male endurance mountain runners performed three maximal oxygen uptake tests at three slope conditions (0, 12.5 and 25%). Metabolic data, step frequency (SF) and step length (SL) were recorded. No significant differences were found in VO2max (63.29 (±3.84), 63.97 (±3.54) and 63.70 (±3.58) mlO2/kg-1/min-1) or associated metabolic data at 0, 12.5 and 25% slope respectively. High intra-individual correlations were found between metabolic data measured in the three conditions. The energy cost of running was significantly different between slopes (0.192 (±0.01), 0.350 (±0.029) and 0.516 (±0.035) mlO2/kg-1/min-1, p < 0.01), 0, 12.5 and 25% respectively. However, Cr0% was not correlated with either Cr25% or Cr12.5% (rs = 0.09 and rs = 0.10), in contrast, Cr25% and Cr12.5% were correlated (rs = 0.78). Step length was positively correlated with speed under the three slope conditions. Step frequency was significantly lower at 25 compared to 12.5 and 0% slope. We found that the maximum aerobic power did not differ between level and graded treadmill tests. However, the increase in Cr on the inclined versus level conditions varied between subjects. None of the measured anthropometric or kinematic variables could explain the higher increase in Cr of some subjects when running uphill. Thus, a short graded (5min at 12.5%) running test should be performed at a submaximal velocity (around 40% of level vVO2max) to enhance understanding of an endurance runner’s uphill capability. Key points In elite endurance mountain runners, there is no difference in VO2max values between level and uphill running. In a homogeneous group of mountain runners, uphill Cr is not associated with level Cr. To assess performance potential of

    The purpose of this study is to evaluate the readability level and content of articles concerning pregnancy and the periodontium which are presented on internet websites. Websites were selected from Google, Yahoo, and Bing. The sites which were excluded were: commercial sites; blogs; dental office sites; sites with articles having fewer than 20 sentences; duplicated search results; and non-secure sites (N = 137). The grade level was determined from the SMOG reading index. Content was scored for specific pregnancy related periodontal content. The mean reading level was 8th grade. The mean number of words with 3 or more syllables in 20 sentences was 38.90. Articles written below the 8th grade level were more likely to recommend brushing twice a day and using a soft-bristled brush. Articles at or above the 8th grade level were more likely to discuss preterm birth and periodontal disease. One article from a national dental organization and 3 from government sites were returned from the searches. Internet articles are written across the literary spectrum. Dental organizations were not adequately represented. Many advertisements, .coms, and non-secure sites pose challenges in seeking health information. Although the internet is a useful tool, practitioners need to provide trustworthy, useful information during clinical visits and encourage national and state medical and dental organizations to provide content in response to search terms that would be typically used.

    This paper explored variation of student numerical and figural reasoning approaches across different pattern generalization types and across grade level. An instrument was designed for this purpose. The instrument was given to a sample of 1232 students from grades 4 to 11 from five schools in Lebanon. Analysis of data showed that the numerical reasoning approach seems to be more dominant than the figural reasoning approach for the near and far pattern generalization types but not for the immediate generalization type. The findings showed that for the recursive strategy, the numerical reasoning approach seems to be more dominant than the figural reasoning approach for each of the three pattern generalization types. However, the figural reasoning approach seems to be more dominant than the numerical reasoning approach for the functional strategy, for each generalization type. The findings also showed that the numerical reasoning was more dominant than the figural reasoning in lower grade levels (grades 4 and 5) for each generalization type. In contrast, the figural reasoning became more dominant than the numerical reasoning in the upper grade levels (grades 10 and 11).

    The aim of this study was to investigate the effects of graded levels of montmorillonite, a constituent of clay, on performance, hematological parameters and bone mineralization in weaned pigs. One hundred and twenty, 35-d-old crossbred pigs (Duroc×Large White×Landrace, 10.50±1.20 kg) were used in a 28-d experiment and fed either an unsupplemented corn-soybean meal basal diet or similar diets supplemented with 0.5, 1.0, 2.5 or 5.0% montmorillonite added at the expense of wheat bran. Each treatment was replicated six times with four pigs (two barrows and two gilts) per replicate. Feed intake declined (linear and quadratic effect, p< 0.01) with increasing level of montmorillonite while feed conversion was improved (linear and quadratic effect, p<0.01). Daily gain was unaffected by dietary treatment. Plasma myeloperoxidase declined linearly (p = 0.03) with increasing dietary level of montmorillonite. Plasma malondialdehyde and nitric oxide levels were quadratically affected (p<0.01) by montmorillonite with increases observed for pigs fed the 0.5 and 1.0% levels which then declined for pigs fed the 2.5 and 5.0% treatments. In bone, the content of potassium, sodium, copper, iron, manganese and magnesium were decreased (linear and quadratic effect, p<0.01) in response to an increase of dietary montmorillonite. These results suggest that dietary inclusion of montmorillonite at levels as high as 5.0% does not result in overt toxicity but could induce potential oxidative damage and reduce bone mineralization in pigs.

    Food intake and circadian rhythms are regulated by hypothalamic neuropeptides and circulating hormones, which could mediate the anti‐ageing effect of calorie restriction (CR). We tested whether these two signaling pathways mediate CR by quantifying hypothalamic transcripts of male C57BL/6 mice exposed to graded levels of CR (10 % to 40 %) for 3 months. We found that the graded CR manipulation resulted in upregulation of core circadian rhythm genes, which correlated negatively with circulating levels of leptin, insulin‐like growth factor 1 (IGF‐1), insulin, and tumor necrosis factor alpha (TNF‐α). In addition, key components in the hunger signaling pathway were expressed in a manner reflecting elevated hunger at greater levels of restriction, and which also correlated negatively with circulating levels of insulin, TNF‐α, leptin and IGF‐1. Lastly, phenotypes, such as food anticipatory activity and body temperature, were associated with expression levels of both hunger genes and core clock genes. Our results suggest modulation of the hunger and circadian signaling pathways in response to altered levels of circulating hormones, that are themselves downstream of morphological changes resulting from CR treatment, may be important elements in the response to CR, driving some of the key phenotypic outcomes.

    The effects of graded atmospheric O2 concentration (12, 14, 16, 18, and 20.6%) on chick performance and propensity to develop ascites were investigated using commercial male broilers. Chicks were housed in calorimetry chambers for 2 wk with incoming air diluted with N to provide the desired O2 concentration at thermoneutral (TN) ambient temperature. Day 14 body weight, weight gain, feed consumption, and gain-to-feed ratio increased (P < 0.01) as O2 concentration incrementally rose from 12 to 20.6%. Body weight was 138 g for the lowest atmospheric O2 level compared to 371 g for 20.6% O2. The greatest treatment difference occurred between the 12 and 14% O2 concentrations. Growth depression appeared related to feed consumption. Ascites heart ratio (AHR), ascites score (AS), right ventricular mass (RVM), and hematocrit (HCT) all increased (P < 0.01) as O2 concentration decreased. Blood HCT appeared to be a more sensitive indicator of physiological change attributable to atmospheric O2 than AHR, AS, or RVM. The data reported herein suggests that 19.6% atmospheric O2 is the minimal allowable level for housing birds within a relatively stress-free, TN environment to avoid cardiac and HCT changes related to ascites.

    To reduce treatment of indolent prostate cancer (PCa), biomarkers are needed to improve identification of patients with a low-risk of having aggressive disease. Over-treatment of these patients occurs because of uncertainty in the aggressiveness of the entire tumor based on the biopsies, which do not accurately sample multifocal tumors. Circulating microRNAs (miRNAs) are stable serum markers and differential miRNA levels occur in men with PCa. The goal of this study was to identify circulating miRNAs that were associated with aggressive or indolent PCa. We measured circulating miRNAs in 150 patients prior to surgery and compared the miRNA levels to the pathology of the entire radical prostatectomy specimen. For this study we used an exceptionally well-characterized cohort of patients who had benign prostatic hyperplasia (BPH), low-grade or high-grade PCa. Low-grade was defined as patients with 100% Gleason grade 3 tumor as determined by step-wise sectioning. High-grade PCa patients had 30-90% Gleason grade 4+5 in the tumor. BPH patients had at least two biopsies negative for PCa. Twenty one miRNAs were selected for analysis. The miRNAs were quantified by RT-qPCR and analyzed by logistic regression. High levels of 14 miRNAs were exclusively present in the serum from patients with low-grade PCa or BPH, compared to men with high-grade PCa who had consistently low levels. The expression levels of the 14 miRNAs were combined into a “miR Score” which had a negative predictive value (NPV) of 0.939 to predict absence of high-grade PCa among PCa and BPH patients. Biochemical recurrence (BCR) was known for the PCa patients and a combined “miR Risk Score” accurately classified a subset of patients with low risk of BCR (NPV 0.941). In summary, measurement of serum miRNAs may have pre-surgical utility in combination with clinical risk calculators to identify patients with low risk of harboring aggressive PCa. PMID:25874774

  17. Hepatorenal syndrome: the 8th international consensus conference of the Acute Dialysis Quality Initiative (ADQI) Group

    2012-01-01

    Introduction Renal dysfunction is a common complication in patients with end-stage cirrhosis. Since the original publication of the definition and diagnostic criteria for the hepatorenal syndrome (HRS), there have been major advances in our understanding of its pathogenesis. The prognosis of patients with cirrhosis who develop HRS remains poor, with a median survival without liver transplantation of less than six months. However, a number of pharmacological and other therapeutic strategies have now become available which offer the ability to prevent or treat renal dysfunction more effectively in this setting. Accordingly, we sought to review the available evidence, make recommendations and delineate key questions for future studies. Methods We undertook a systematic review of the literature using Medline, PubMed and Web of Science, data provided by the Scientific Registry of Transplant Recipients and the bibliographies of key reviews. We determined a list of key questions and convened a two-day consensus conference to develop summary statements via a series of alternating breakout and plenary sessions. In these sessions, we identified supporting evidence and generated recommendations and/or directions for future research. Results Of the 30 questions considered, we found inadequate evidence for the majority of questions and our recommendations were mainly based on expert opinion. There was insufficient evidence to grade three questions, but we were able to develop a consensus definition for acute kidney injury in patients with cirrhosis and provide consensus recommendations for future investigations to address key areas of uncertainty. Conclusions Despite a paucity of sufficiently powered prospectively randomized trials, we were able to establish an evidence-based appraisal of this field and develop a set of consensus recommendations to standardize care and direct further research for patients with cirrhosis and renal dysfunction.

    The 8th International Conference on Non-Contact Atomic Force Microscopy, held in Bad Essen, Germany, from 15 18th August 2005, attracted a record breaking number of participants presenting excellent contributions from a variety of scientific fields. This clearly demonstrated the high level of activity and innovation present in the community of NC-AFM researchers and the continuous growth of the field. The strongest ever participation of companies for a NC-AFM meeting is a sign for the emergence of new markets for the growing NC-AFM community; and the high standard of the products presented at the exhibition, many of them brand-new developments, reflected the unbroken progress in technology. The development of novel technologies and the sophistication of known techniques in research laboratories and their subsequent commercialization is still a major driving force for progress in this area of nanoscience. The conference was a perfect demonstration of how progress in the development of enabling technologies can readily be transcribed into basic research yielding fundamental insight with an impact across disciplines. The NC-AFM 2005 scientific programme was based on five cornerstones, each representing an area of vivid research and scientific progress. Atomic resolution imaging on oxide surfaces, which has long been a vision for the catalysis community, appears to be routine in several laboratories and after a period of demonstrative experiments NC-AFM now makes unique contributions to the understanding of processes in surface chemistry. These capabilities also open up new routes for the analysis of clusters and molecules deposited on dielectric surfaces where resolution limits are pushed towards the single atom level. Atomic precision manipulation with the dynamic AFM left the cradle of its infancy and flourishes in the family of bottom-up fabrication nanotechnologies.

    2013-01-01

    Purpose The capacity of nadir CA-125 levels to predict the prognosis of epithelial ovarian cancer remains controversial. This study aimed to explore whether the nadir CA-125 serum levels could predict the durations of overall survival (OS) and progression free survival (PFS) in patients with high-grade serous ovarian cancer (HG-SOC) from the USA and PRC. Materials and methods A total of 616 HG-SOC patients from the MD Anderson Cancer Center (MDACC, USA) between 1990 and 2011 were retrospectively analyzed. The results of 262 cases from the Jiangsu Institute of Cancer Research (JICR, PRC) between 1992 and 2011 were used to validate the MDACC data. The CA-125 immunohistochemistry assay was performed on 280 tissue specimens. The Cox proportional hazards model and the log-rank test were used to assess the associations between the clinicopathological characteristics and duration of survival. Results The nadir CA-125 level was an independent predictor of OS and PFS (p < 0.01 for both) in the MDACC patients. Lower nadir CA-125 levels (≤10 U/mL) were associated with longer OS and PFS (median: 61.2 and 16.8 months with 95% CI: 52.0–72.4 and 14.0–19.6 months, respectively) than their counterparts with shorter OS and PFS (median: 49.2 and 10.5 months with 95% CI: 41.7–56.7 and 6.9–14.1 months, respectively). The nadir CA-125 levels in JICR patients were similarly independent when predicting the OS and PFS (p < 0.01 for both). Nadir CA-125 levels less than or equal to 10 U/mL were associated with longer OS and PFS (median: 59.9 and 15.5 months with 95% CI: 49.7–70.1 and 10.6–20.4 months, respectively), as compared with those more than 10 U/mL (median: 42.0 and 9.0 months with 95% CI: 34.4–49.7 and 6.6–11.2 months, respectively). Baseline serum CA-125 levels, but not the CA-125 expression in tissues, were associated with the OS and PFS of HG-SOC patients in the MDACC and JICR groups. However, these values were not independent. Nadir CA-125

    The results are summarized of a program to demonstrate the feasibility of Bubble Domain Memory Technology as a mass memory medium for spacecraft applications. The design, fabrication and test of a partially populated 10 to the 8th power Bit Data Recorder using 100 Kbit serial bubble memory chips is described. Design tradeoffs, design approach and performance are discussed. This effort resulted in a 10 to the 8th power bit recorder with a volume of 858.6 cu in and a weight of 47.2 pounds. The recorder is plug reconfigurable, having the capability of operating as one, two or four independent serial channel recorders or as a single sixteen bit byte parallel input recorder. Data rates up to 1.2 Mb/s in a serial mode and 2.4 Mb/s in a parallel mode may be supported. Fabrication and test of the recorder demonstrated the basic feasibility of Bubble Domain Memory technology for such applications. Test results indicate the need for improvement in memory element operating temperature range and detector performance.

  2. Role of acidic residues in helices TH8-TH9 in membrane interactions of the diphtheria toxin T domain.

    The pH-triggered membrane insertion of the diphtheria toxin translocation domain (T domain) results in transferring the catalytic domain into the cytosol, which is relevant to potential biomedical applications as a cargo-delivery system. Protonation of residues is suggested to play a key role in the process, and residues E349, D352 and E362 are of particular interest because of their location within the membrane insertion unit TH8-TH9. We have used various spectroscopic, computational and functional assays to characterize the properties of the T domain carrying the double mutation E349Q/D352N or the single mutation E362Q. Vesicle leakage measurements indicate that both mutants interact with the membrane under less acidic conditions than the wild-type. Thermal unfolding and fluorescence measurements, complemented with molecular dynamics simulations, suggest that the mutant E362Q is more susceptible to acid destabilization because of disruption of native intramolecular contacts. Fluorescence experiments show that removal of the charge in E362Q, and not in E349Q/D352N, is important for insertion of TH8-TH9. Both mutants adopt a final functional state upon further acidification. We conclude that these acidic residues are involved in the pH-dependent action of the T domain, and their replacements can be used for fine tuning the pH range of membrane interactions.

    2005-03-01

    In this study, students' views on the nature of science (NOS) were investigated with the use of a large-scale survey. An empirically derived multiple-choice format questionnaire was administered to 1702 Korean 6th, 8th, and 10th graders. The questionnaire consisted of five items that respectively examined students' views on five constructs concerning the NOS: purpose of science, definition of scientific theory, nature of models, tentativeness of scientific theory, and origin of scientific theory. Students were also asked to respond to an accompanying open-ended section for each item in order to collect information about the rationale(s) for their choices. The results indicated that the majority of Korean students possessed an absolutist/empiricist perspective about the NOS. It was also found that, on the whole, there were no clear differences in the distributions of 6th, 8th, and 10th graders' views on the NOS. In some questions, distinct differences between Korean students and those of Western countries were found. Educational implications are discussed.

  4. Using GRADE to respond to health questions with different levels of urgency.

    Thayer, Kristina A; Schünemann, Holger J

    2016-01-01

    Increasing interest exists in applying the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to environmental health evidence. While ideally applied to evidence synthesized in systematic reviews and corresponding summary tables, such as evidence profiles, GRADE's correct application requires that "the evidence that was assessed and the methods that were used to identify and appraise that evidence should be clearly described." In this article, we suggest that GRADE could be applied to evidence assembled from narrative reviews, modelled (indirect) evidence, or evidence assembled as part of a rapid response, if the underlying judgments about the certainty in this evidence are based on the relevant GRADE domains and provided transparently. Health questions that require assessing the certainty in a body of evidence to provide trustworthy answers may range from hours, to days or weeks, to a few months to scenarios that allow assessing evidence without short-term time pressures. Time frames of emergent, urgent or rapid evidence assessments will often require relying on existing summaries or rapidly compiling the available evidence and making assessments. Even without available full systematic reviews, expressing the certainty in the evidence can provide useful guidance for users of the evidence and those who evaluate certainty in effects. The ratings also help clarifying disagreement between organizations tackling similar questions about the evidence. Using the structured GRADE domains, narrative or other summaries of the evidence can be presented transparently. PMID:27126781

    The objective of this study was to determine the acute gastrointestinal effects caused by the consumption of drinking water containing graded levels of added copper. Sixty healthy, adult women were randomly assigned to receive copper [Cu(II)] at four concentrations in their drinking water following a Latin-square design. Each group (n = 15) received tap water with no added copper, 1, 3, and 5 mg Cu/l of added copper sulfate for a 2-week study period, followed by 1 week of standard tap water. The subjects recorded their water consumption and gastrointestinal symptoms daily on a special form. The average daily consumption of water was 1.64 liters per subject, regardless of the amount of copper added. Final serum copper, ceruloplasmin, and liver enzymes were measured in all subjects and were not different from baseline concentrations. Twenty-one subjects (35%) recorded gastrointestinal disturbances sometime during the study, 9 had diarrhea, some with abdominal pain and vomiting, and 12 subjects presented abdominal pain, nausea, or vomiting. There was no association between copper levels in drinking water and diarrhea. However, nausea, abdominal pain, or vomiting were significantly related to copper concentrations in water. The recorded incidence rate of these symptoms was 5, 2, 17, and 15% while ingesting water with 0, 1, 3, and 5 mg Cu/l, respectively (overall [chi]2 = 11.3, p<0.01; Cu [less than/equal to]1 mg/l versus Cu [Greater than/equal to]3 mg/l, [chi]2, p<0.01). When subjects interrupted their consumption of drinking water with added copper, most symptoms disappeared. We conclude that under the conditions of the study, there was no association between aggregate copper in drinking water within the range of 0-5 mg/l and diarrhea, but a [Greater than/equal to]3 mg Cu/l level of ionized copper was associated with nausea, abdominal pain, or vomiting. Additional studies with sufficient numbers of subjects are needed to define thresholds for specific gastrointestinal

    This study was conducted for 10 weeks with the aim of investigating the erythrocyte membrane integrity as measured by erythrocyte osmotic fragility and excitability scores of rabbits fed graded level of Hibiscus sabdariffa calyx (HSC). Twenty weaners' rabbit of both sexes were used for the study and were placed on four experimental diets which contain the following percentages of HSC 0 %, 25 %, 50 %, 75 %, as feed additive and were added at 0 g, 62.5 g, 125 g, 187.5 g designated as T1, T2, T3 and T4 experimental diets. Excitability scores were measured weekly as described by Voisnet et al. (1997). At the end of the experiment, the rabbits were slaughtered by severing the jugular vein. A Blood sample (2 ml) was collected from each rabbit into sampled bottles, containing the Na EDTA as anticoagulant for hematological analysis. Packed cell volume (PCV) Haemoglobin concentration (Hb), Total red blood cell (RBC) count, Total leukocyte count as well as differential leukocyte was determined using standard method. The percentage haemolysis recorded at 0.3 % to 0.8 % was significantly (P < 0.05) higher in rabbits in T1 compared to the remaining 3 diets. The result of excitability score shows that rabbit on diet 1 and 2 had a lower value which was significantly (P < 0.05) lower than rabbits on diets 3 and 4 with a value of 65.5 ± 5.0 and 70.00 ± 5.50 % respectively. In conclusion this study demonstrated for the first time that chronic administration of HSC improves haematological parameters, brain mood and function as well as maintaining erythrocyte membrane integrity.

    Overexpression of human epidermal growth factor receptor 2 (HER2) is an important prognostic and predictive marker of response to anti-HER2 therapy in breast cancer. Our goal was to analyze the prognostic significance of moderate expression of HER2 in breast cancer with intermediate differentiation grade. We performed a multicenter retrospective register study of 8494 patients with primary non-metastatic breast cancer admitted between 2000 and 2011 to eight Clinics in Saxony-Anhalt, federal state of Germany. Patients were divided into three groups according to their HER2 score: 4073 were classified as HER2 negative (HER2 0 and 1+), 822 HER2 moderate (HER2 2+/HER2), and 1238 HER2 positive (HER2 3+ or HER2 2+/HER2+). HER2-positive cases were excluded from analysis. Tumors with moderate HER2 (HER2 2+) expression demonstrated an aggressive behavior and worse patient survival compared with HER2 0 and 1+ status. HER2 2+ status was associated with shorter median overall survival (OS) (P < 0.0001) in breast cancer patients with an intermediate grade of differentiation. Comparing low-grade and high-grade tumors, HER2 moderate expression did not significantly influence patient survival. In multivariate analysis after adjustment for other prognostic factors HER2 2+ status remained an unfavorable prognostic factor for OS (HR 1.224, 95 % CI 1.059-1.415, P = 0.006) in breast cancer patients with an intermediate grade of differentiation. HER2 2+ status is an unfavorable prognostic factor regarding the OS of breast cancer patients with intermediate grade of differentiation and could be used to identify patients, who may benefit from adjuvant therapy.

  2. School-based exposure to hazardous air pollutants and grade point average: A multi-level study.

    The problem of environmental health hazards around schools is serious but it has been neglected by researchers and analysts. This is concerning because children are highly susceptible to the effects of chemical hazards. Some ecological studies have demonstrated that higher school-level pollution is associated with lower aggregate school-level standardized test scores likely, related to increased respiratory illnesses and/or impaired cognitive development. However, an important question remains unexamined: How do school-level exposures impact individual children's academic performance? To address this, we obtained socio-demographic and grades data from the parents of 1888 fourth and fifth grade children in the El Paso (Texas, USA) Independent School District in 2012. El Paso is located on the US-side of the Mexican border and has a majority Mexican-origin population. School-based hazardous air pollution (HAP) exposure was calculated using census block-level US Environmental Protection Agency National Air Toxics Assessment risk estimates for respiratory and diesel particulate matter (PM). School-level demographics were obtained from the school district. Multi-level models adjusting for individual-level covariates (e.g., age, sex, race/ethnicity, English proficiency, and economic deprivation) and school-level covariates (e.g., percent of students economically disadvantaged and student-teacher ratio) showed that higher school-level HAPs were associated with lower individual-level grade point averages. An interquartile range increase in school-level HAP exposure was associated with an adjusted 0.11-0.40 point decrease in individual students' grade point averages (GPAs), depending on HAP type and emission source. Respiratory risk from HAPs had a larger effect on GPA than did diesel PM risk. Non-road mobile and total respiratory risk had the largest effects on children's GPA of all HAP variables studied and only mother's level of education had a larger effect than those

  3. The impact of graded levels of daylength on turkey productivity to eighteen weeks of age.

    2016-05-01

    The impact of graded levels of day-length on the productivity of hens and toms was studied in two trials. Daylength treatments (trts) were 14 (14L), 17 (17L), 20 (20L), and 23 (23L) h and were started at 10 d of age. Turkeys (720 hens and 480 toms) were randomly allocated to 8 rooms (2 rooms per lighting trt) with six pens (3 hen--30 per pen and 3 tom--20 per pen) per room in each trial. Body weight (BW) was assessed at 0, 10, 21, 42, 63, 84, and 126 d of age; feed consumption (FC) was measured for the time periods between body weight determinations and feed efficiency (G:F; g of gain/g of feed) was calculated from BW and FC values. Birds were checked daily for mortality and culls, and affected birds were sent for necropsy. Data were analyzed according to a completely randomized block design with trial as the block and rooms nested within lighting trts. Regression analysis was used to study the relationship between dependent variables and daylength. Significance was declared at P≤ 0.05 and trends at P≤ 0.10. At both 21 and 42 d, body weight increased linearly with increasing daylength. At 84 d weights of toms decreased in a quadratic fashion and hen weights were unaffected. At 126 d, both tom and hen weights decreased linearly as daylength increased, with the magnitude of response gender dependent. Feed consumption corresponded with body weight changes, increasing for d 10 to 21, and 21 to 42 and decreasing for d 63 to 84, 84 to 105, and 105 to 126 with increasing daylength. Feed efficiency (G:F) was not affected by daylength for 10 to 84, 10 to 105 and 10 to 126 d periods. The incidence of mortality and culling was not affected by daylength for the 10 to 84 d period, but increased in a quadratic manner with increasing daylength for the 10 to 105 and 10 to 126 d periods. To conclude, daylength affects the growth and feed intake of turkeys in an age and gender-specific manner, and mortality and culling increase with longer daylength. PMID:26976908

  15. Memorization techniques: Using mnemonics to learn fifth grade science terms

    NASA Astrophysics Data System (ADS)

    Garcia, Juan O.

    The purpose of this study was to determine whether mnemonic instruction could assist students in learning fifth-grade science terminology more effectively than traditional-study methods of recall currently in practice The task was to examine if fifth-grade students were able to learn a mnemonic and then use it to understand science vocabulary; subsequently, to determine if students were able to remember the science terms after a period of time. The problem is that in general, elementary school students are not being successful in science achievement at the fifth grade level. In view of this problem, if science performance is increased at the elementary level, then it is likely that students will be successful when tested at the 8th and 10th grade in science with the Texas Assessment of Knowledge and Skills (TAKS) in the future. Two research questions were posited: (1) Is there a difference in recall achievement when a mnemonic such as method of loci, pegword method, or keyword method is used in learning fifth-grade science vocabulary as compared to the traditional-study method? (2) If using a mnemonic in learning fifth-grade science vocabulary was effective on recall achievement, would this achievement be maintained over a span of time? The need for this study was to assist students in learning science terms and concepts for state accountability purposes. The first assumption was that memorization techniques are not commonly applied in fifth-grade science classes in elementary schools. A second assumption was that mnemonic devices could be used successfully in learning science terms and increase long term retention. The first limitation was that the study was conducted on one campus in one school district in South Texas which limited the generalization of the study. The second limitation was that it included random assigned intact groups as opposed to random student assignment to fifth-grade classroom groups.

  16. Pharmacovigilance Discussion Forum--The European Generic Medicines Association's 8th Annual Meeting (January 21, 2015--London, UK).

    PubMed

    Lam, S

    2015-01-01

    The practice and science of pharmacovigilance first emerged following the disaster caused by thalidomide in 1961, which led to the initiation of systemic international efforts to address drug safety issues spearheaded by the WHO. Systems were developed in member states of the WHO to analyze cases of adverse drug reactions (ADRs) and collate these data into a central database to aid national drug regulatory authorities in improving safety profiles of medicines. Pharmacovigilance is a key public health function for monitoring all medicinal products to assess their quality, efficacy and safety before and following authorization. These medicines are continually assessed to detect any aspect that could compromise their safety, and ensure that the necessary measures are taken. In July 2012, new legislation for pharmacovigilance in the E.U. came into effect as a result of the changes set out in the Directive 2010/84/EU and the European Commission (EC) implementing Regulation (EU) No 520/2012 to reduce the increasing number of ADRs. The latest developments in pharmacovigilance in Europe, including news on E.U. pharmacovigilance legislation, were discussed at the 8th European Generic Medicines Association (EGA) Pharmacovigilance Discussion Forum. The meeting facilitated constructive dialogue between regulators and industry on a range of topics including how to simplify pharmacovigilance activities and improve the processes of risk management plans, periodic safety update reports, signal detection, joint studies and inspections.

    In 1993, Przyklenk and colleagues made the intriguing experimental observation that 'brief ischemia in one vascular bed also protects remote, virgin myocardium from subsequent sustained coronary artery occlusion' and that this effect'... may be mediated by factor(s) activated, produced, or transported throughout the heart during brief ischemia/reperfusion'. This seminal study laid the foundation for the discovery of 'remote ischemic conditioning' (RIC), a phenomenon in which the heart is protected from the detrimental effects of acute ischemia/reperfusion injury (IRI), by applying cycles of brief ischemia and reperfusion to an organ or tissue remote from the heart. The concept of RIC quickly evolved to extend beyond the heart, encompassing inter-organ protection against acute IRI. The crucial discovery that the protective RIC stimulus could be applied non-invasively, by simply inflating and deflating a blood pressure cuff placed on the upper arm to induce cycles of brief ischemia and reperfusion, has facilitated the translation of RIC into the clinical setting. Despite intensive investigation over the last 20 years, the underlying mechanisms continue to elude researchers. In the 8th Biennial Hatter Cardiovascular Institute Workshop, recent developments in the field of RIC were discussed with a focus on new insights into the underlying mechanisms, the diversity of non-cardiac protection, new clinical applications, and large outcome studies. The scientific advances made in this field of research highlight the journey that RIC has made from being an intriguing experimental observation to a clinical application with patient benefit.

    Tripathi, M K; Mondal, D; Karim, S A

    2008-02-01

    The aim of this study was to explore possibilities of utilization of animal feed grade damaged wheat (ADW) in lamb feeding, and assess the effect of ADW and its aflatoxin on intake, growth, haematology, blood biochemical constituents and immunological status. The ADW is a slightly mouldy feed resource, which is not suitable for human consumption. The experimental ADW contained dry matter (DM) 964, organic matter 974, crude protein 153, cellulose 205 and lignin 24, and starch 732 g/kg DM. ADW also contained aflatoxin B1 50 microg/kg due to mould infestation. Thirty-five weaner lambs (90 +/- 15 days of age and 16.1 +/- 0.82 kg body weight) in a randomized design were fed for 91 days on one of four composite feed mixtures (roughage to concentrate ratio of 25:75) containing 0, 118, 235, 353 or 470 g/kg ADW, which replaced equal amounts of maize and at these inclusion levels ADW replaced 0%, 25%, 50%, 75% and 100% maize in lamb diets respectively. Dry matter intake (DMI) was similar in different level of ADW fed lambs but ADW inclusion linearly (p = 0.016) reduced DMI. Average daily gain (g/day) was higher (p = 0.038) in lambs fed 353 g ADW diet. Haematological attributes viz. WBC, haemoglobin (Hb) and mean corpuscular volume did not affect by ADW feeding whereas it increased haematocrit, mean cell Hb and decreased neutrophil, RBC counts and mean cell Hb concentration. Blood glucose and urea-N increased whereas albumin and protein level reduced by ADW feeding. ADW feeding of lambs did not affect serum IgG level. The activities of serum aspartate aminotransferase, alkaline phosphates and acid phosphates were not affected, whereas alanine aminotransferase increased linearly (p = 0.001) with increasing levels of ADW. It is concluded that ADW containing aflatoxin B1 50 microg/kg DM can safely be incorporated in growing lamb feeding up to 353 g/kg diet without affecting growth and cellular immunity, however ADW may induce a transient alteration of hepatic enzymatic

  11. Content, format, gender and grade level differences in elementary students' ability to read science materials as measured by the cloze procedure

    NASA Astrophysics Data System (ADS)

    Williams, Richard L.; Yore, Larry D.

    Present instructional trends in science indicate a need to reexamine a traditional concern in science education: the readability of science textbooks. An area of reading research not well documented is the effect of color, visuals, and page layout on readability of science materials. Using the cloze readability method, the present study explored the relationships between page format, grade level, sex, content, and elementary school students ability to read science material. Significant relationships were found between cloze scores and both grade level and content, and there was a significant interaction effect between grade and sex in favor of older males. No significant relationships could be attributed to page format and sex. In the area of science content, biological materials were most difficult in terms of readability followed by earth science and physical science. Grade level data indicated that grade five materials were more difficult for that level than either grade four or grade six materials were for students at each respective level. In eight of nine cases, the science text materials would be classified at or near the frustration level of readability. The implications for textbook writers and publishers are that science reading materials need to be produced with greater attention to readability and known design principles regarding visual supplements. The implication for teachers is that students need direct instruction in using visual materials to increase their learning from text material. Present visual materials appear to neither help nor hinder the student to gain information from text material.

  12. Interpreting GRADE's levels of certainty or quality of the evidence: GRADE for statisticians, considering review information size or less emphasis on imprecision?

    PubMed

    Schünemann, Holger J

    2016-07-01

    This article responds to issues raised by Antilla et al. in the Journal of Clinical Epidemiology about the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group's approach to rating imprecision and GRADE's use of statistics. They argue that GRADE confuses statistical terms and should provide a stepwise rating of imprecision for making decisions. Here, a clarification of those perceptions is provided. GRADE's ratings of imprecision and other quality of evidence domains is an iterative process that may or may not consider people important thresholds of effects when systematic review authors rate imprecision. Regardless of ratings in systematic reviews, those suggesting decisions such as guideline panels, should consider if they agree or need to revise these suggested thresholds to make informed ratings about imprecision. Decision relevant thresholds are the result of a complex interplay between critical outcomes for a decision-making. The certainty in the evidence of one critical outcome and the resulting possible certainty range, which I conceptualize in this article, may influence ratings of other outcomes. To relieve systematic review authors of the often challenging burden of defining worthwhile or important effects for judging precision based on the optimal information size (OIS), a modified OIS or review information size (RIS) could be used to rate imprecision at the systematic review stage. The RIS focuses only on plausible rather plausible and worthwhile effects. The advantages of using the RIS include avoiding the reliance on statistical significance alone and the varying thresholds resulting from the importance and the baseline risk of the outcome on which the OIS relies. Finally, I argue that GRADE's certainty in the evidence is related to the statistical definition of accuracy but given GRADE's broad application to other ratings of certainty such as qualitative evidence, statistical accuracy does not serve as a definition

    Differences were examined in Theory of Planned Behaviour determinants of students' intention to smoke including parents' attitudes towards smoking and parents' current cigarette use among Greek students of different school grade levels. Students (N = 763) aged 10-18 years reported their attitudes towards smoking, subjective norms, perceived behavioural control, self-identity and intention to smoke while their parents (N = 525) reported their attitudes towards smoking and their current cigarette use. All the TPB variables increased from lower to higher school grade level. Multi-sample path analyses showed that parent's attitudes towards smoking positively predicted students' intention to smoke only for elementary school children. Parents' current cigarette use did not contribute significantly. Students' attitudes, perceived behavioural control and self-identity predicted systematically intention to smoke in contrast to the subjective norm that did not contribute at all. Perceived behavioural control contributed to a higher degree in intention to smoke for senior high school students compared to the junior high school and elementary students. Self-identity contributed to a higher degree in intention to smoke for elementary compared to the junior high school students. The results of this study suggests that the determinants of smoking vary between early and late adolescence. PMID:21834644

    2004-10-01

    It is now almost two decades since Bernard Schutz organized a landmark meeting on data analysis for gravitational wave detectors at the University of Cardiff, UK [1]. The proceedings of that meeting make interesting reading. Among the issues discussed were optimal ways to carry out searches for binary inspiral signals, and ways in which the projected growth in computer speed, memory and networking bandwidth would influence searches for gravitational wave signals. The Gravitational Wave Data Analysis Workshop traces its history to the mid-1990s. With the construction of the US LIGO detectors and the European GEO and VIRGO detectors already underway, Kip Thorne and Sam Finn realized that it was important for the world-wide data analysis community to start discussing some of the big unsettled issues in analysis. What was the optimal way to perform a pulsar search? To ensure confident detection, how accurately did binary inspiral waveforms have to be calculated? It was largely Kip and Sam's initiative that got the GWDAW started. The first (official) GWDAW was hosted by Rai Weiss at Massachusetts Institute of Technology, USA in 1996, as a follow-on to an informal meeting organized in the previous year by Sam Finn. I have pleasant memories of this first MIT GWDAW. I was new to the field and remember my excitement at learning that I had many colleagues interested in (and working on) the important issues. I also remember how refreshing it was to hear a pair of talks by Pia Astone and Marialessandra Papa who were not only studying methods but had actually carried out serious pulsar and burst searches using data from the Rome resonant bar detectors. A lot has changed since then. This issue is the Proceedings of the 8th Annual Gravitational Wave Data Analysis Workshop, held on 17-20 December 2003 at the University of Wisconsin-Milwaukee, USA. Many of the contributions concern technical details of the analysis of real data from resonant mass and interferometric detectors

    This issue of Superconductor Science and Technology (SuST) contains plenary and invited papers presented at the 8th European Conference on Applied Superconductivity (EUCAS '07) held in Brussels, Belgium between 16-20 September 2007. All the papers that were submitted to the Conference Proceedings and accepted by the referees are published in Journal of Physics: Conference Series (JPCS). The scientific aims of EUCAS '07 followed the tradition established at the preceding conferences in Göttingen (Germany), Edinburgh (United Kingdom), Eindhoven (The Netherlands), Sitges (Spain), Lyngby (Denmark), Sorrento (Italy) and Vienna (Austria). The focus was on the interplay between the most recent developments in superconductor research and the positioning of applications of superconductivity in the marketplace. Although initially founded as an exchange forum mainly for European scientists, it has gradually developed into a truly international meeting with significant attendance from the Far East and the United States. Under the guidance of ESAS (the European Society for Applied Superconductivity), this Brussels conference was jointly organized by the University of Ghent and the University of Liège and attracted 795 participants to the scientific programme, including 173 students. Participants from 46 countries included considerable attendance from the Far East (30%) and from the United States and Canada (7%). The latest developments from 30 companies were presented, and 13 plenary and 28 invited lectures highlighted the state-of-the-art in the area of materials (large- as well as small-scale applications were presented). A total of 347 papers from those submitted were selected for publication in JPCS and SuST. EUCAS '07 stimulated optimism and enthusiasm for this fascinating field of research and its technological potential, especially among the numerous young researchers attending this conference. In addition, it gave the leading scientific authorities a forum in which

    The objective of the study was to determine effect of feeding fibrous diets on performance and biochemical profiles of finishing pigs. A total of 84 clinically healthy male pigs were used in the experiment. Body weight of the pigs at the beginning of the experiment was 85 ± 10.1 kg. Maize cob (MC), sunflower hulls (SH), lucerne hay (LH) and dried citrus pulp (PU) were incorporated in a basal diet for finishing pigs at different inclusion levels of 0, 80, 160, 240, 320 and 400 g/kg. Effects of week of feeding, fibre source and inclusion level of fibre were significant (P < 0.05). Pigs consumed more LH compared to MC, SH and PU. Average daily gain was high for pigs consuming diets with inclusion levels of 0, 80, 160 and 240 g/kg and low for pigs consuming 320 and 400 g/kg inclusion level of fibre in a diet. There was an increase in serum total concentration (TP) with an increase in PU, MC and LH in pig diets (P < 0.05). Creatine kinase (CK) concentrations decreased as levels of PU, LH and MC increased (P < 0.05). Increasing inclusion level of LH and SH in pig diets resulted in an increase in glycated haemoglobin concentration (P < 0.05). It can be concluded that level of PU, LH, MC and SH in diets of finishing pigs negatively influences average daily feed intake, average daily gain and biochemical profiles. PMID:26984596

    Alpha-lactose monohydrate is widely used as an excipient in dry powder inhalers, and plays a very important role in the efficiency of the drug delivery. Due to the processing, low levels of amorphous lactose could be present in the blends. Varying amounts could have a strong effect on the efficiency of drug delivery of the powder blends. Therefore, the accurate measurement of low levels of amorphous lactose content is very important. A new method was developed to measure the amorphous content, based on dynamic vapour sorption (DVS). In contrast to the traditional re-crystallization approach of amorphous lactose, the new method is based on moisture sorption isotherms. Moisture sorption isotherms of blends of crystalline alpha-lactose and freeze-dried or spray-dried amorphous lactose were measured. By fitting the data with a Brunauer, Emmett, and Teller (BET) isotherm, a linear correlation was found between measured and actual amorphous content for the whole range of 0.1-100%. Differences between freeze-dried and spray-dried lactose, due to different molecular arrangements, could be removed by a preconditioning the samples at 35% RH prior to the isotherm measurement. It was shown that accurate determination of very low concentrations of amorphous lactose content is possible using moisture sorption isotherm analyses. PMID:20493937

  15. The optimum level of parent participation: A study of three intensity levels of parent involvement during three "Playtime is Science" units in three third-grade classes

    NASA Astrophysics Data System (ADS)

    Gooden, Kelly Lynn

    The study describes the experience of introducing three intensity levels of parent participation in three third-grade classes for science instruction using Playtime is Science; an equity curriculum that utilizes parent participation. The study sought to determine the optimum level of participation by ascertaining the most influential aspect of involvement on proficiency scores and the most important aspect of involvement to participants. The levels of participation intensity were distinguished by: (1) the number of parents in the classroom; (2) the responsibilities of the parents; (3) the training received; and (4) the number of students with whom the parents worked. Involvement at each level would potentially manifest aspects of role modeling, lowered student-to-adult instructional ratio, and parent expertise to varying degrees. The three levels of participation were introduced during explorations in three Playtime is Science units following a rotation schedule. Student proficiency was assessed through scores on pre- and post-tests, journals, and discourse. ANCOVA was used to identify main and interaction effects of the independent variables (class, unit and level) on student proficiency taking into account existing differences in groups. Participant attitudes were assessed through journals and interviews. Observations of explorations triangulated findings and assessed participant interactions. Field notes, transcripts and photographs were coded according to the aspects of parent involvement. The results showed level of parent intensity of involvement had no affect on proficiency scores. Therefore, no aspect of parent involvement was determined to be the most influential. Participants felt that lowered instructional ratio and role modeling were the most important aspects of involvement. The level of involvement that utilized the lowest ratio and the most role modeling was level III, small group facilitators. Level III was recognized as the optimum level of

  1. Nitrogen metabolism, tissue carnosine concentration and blood chemistry of gravid swine fed graded levels of histidine.

    1977-01-01

    Three nitrogen metabolism experiments were conducted to determine the qualitative and quantitative histidine need of first-litter gilts during the last third of pregnancy. A completely purified, crystalline 8amino acid diet was formulated to meet all nutrient needs of the gravid gilt when 2 kg/day was fed. Experiments 1 and 2 were 9-day nitrogen balance studies, each consisting of three littermate gilts subjected to three levels of dietary L-histidine in a Latin square arrangement of treatments. Nitrogen retention was depresed, but not significantly, when less than 0.12% histidine was fed. Complete deletion of histidine, however, did not depress retention below that observed when 0.06% was fed. This suggested that either histidine biosynthesis or its release from endogenous reserves was confounding retention data. Therefore in a third experiment, two gilts were fed a histidine-free diet for 24 days in an attempt to deplete endogenous reserves. For comparison, two siblings were fed 0.12% histidine during this same period. Nitrogen retention tended to be lower for gilts fed the histidine-free diet during each of three consecutive collection periods. Blood hemoglobin, muscle and olfactory bulb carnosine concentration, plasma protein and glutamic-oxaloacetic transaminase activity, and blood urea nitrogen were all unaffected by treatment. Offspring from gilts fed the histidine-free diet had lower blood hemoglobin concentrations than their counterparts from gilts receiving histidine. A tentative recommendation of 0.12% dietary L-histidine would seem justified for gravid swine. PMID:833672

    Arsenic exposure in children is a public health concern but is understudied in relation to the predictors, and effects of low-level exposure. We examined the extent and dietary predictors of exposure to inorganic arsenic in 5-8 year old children from Montevideo, Uruguay. Children were recruited at school; 357 were enrolled, 328 collected morning urine samples, and 317 had two 24-h dietary recalls. Urinary arsenic metabolites, i.e. inorganic arsenic (iAs), methylarsonic acid (MMA), and dimethylarsinic acid (DMA), were measured using high-performance liquid chromatography with hydride generation and inductively coupled plasma mass spectrometry (HPLC-HG-ICP-MS), and the sum concentration (U-As) used for exposure assessment. Proportions of arsenic metabolites (%iAs, %MMA and %DMA) in urine were modelled in OLS regressions as functions of food groups, dietary patterns, nutrient intake, and nutritional status. Exposure to arsenic was low (median U-As: 9.9µg/L) and household water (water As: median 0.45µg/L) was not a major contributor to exposure. Children with higher consumption of rice had higher U-As but lower %iAs, %MMA, and higher %DMA. Children with higher meat consumption had lower %iAs and higher %DMA. Higher scores on "nutrient dense" dietary pattern were related to lower %iAs and %MMA, and higher %DMA. Higher intake of dietary folate was associated with lower %MMA and higher %DMA. Overweight children had lower %MMA and higher %DMA than normal-weight children. In summary, rice was an important predictor of exposure to inorganic arsenic and DMA. Higher meat and folate consumption, diet rich in green leafy and red-orange vegetables and eggs, and higher BMI contributed to higher arsenic methylation capacity. PMID:26828624

    Clark, Lisa A.

    The purposes of this study were to identify the attitudes and beliefs content teachers have concerning teaching reading in the content area to below level readers and to identify specific instructional strategies that are used to teach students who are below grade level the content area material. Twelve participants were selected, using maximum variation sampling, based on the grade level and content area they taught. Data was collected from middle school content area teachers using interviews, surveys, observations, and document examination in an attempt to identify attitudes, beliefs, and specific challenges content teachers face instructing below grade level readers. The data was collected, coded and analyzed for specific commonalities. The constructivist's theory served as the framework for the study with emphasis on experiential learning. The experiences that the participants had as early learners, older students, and adult teachers mold their level of efficacy, the way they teach, and the way the view teaching and learning. Based on the data collected and analyzed, common attitudes and beliefs were present among the participants. Common instructional strategies used with below level learners were also identified. The challenges content area teachers face were also recognized. Recommendations were made to school districts, teacher prep programs administrators and to others for further research.

    Glial tumours are a devastating, poorly understood condition carrying a gloomy prognosis for which clinicians sorely lack reliable predictive parameters facilitating a sound treatment strategy. Tp73, a p53 family member, expresses two main classes of isoforms--transactivatory activity (TA)p73 and DeltaTAp73--exhibiting tumour suppressor gene and oncogene properties, respectively. The authors examined their expression status in high- and low-grade adult gliomas. Isoform-specific real-time reverse transcription-polymerase chain reaction was used for the analysis of Tp73 isoform transcript expression in a series of 51 adult patients harbouring glial tumours, in order to compare tumour grades with each other, and with non-tumoural samples obtained from epileptic patients as well. Our data demonstrate increase of TAp73 and DeltaTAp73 transcript levels at onset and early stage of the disease. We also show that DeltaEx2-3 isoform expression in low-grade tumours anticipates clinical and imaging progression to higher grades, and correlates to the patients' survival. Expression levels of P1 promoter generated Tp73 isoforms--and particularly DeltaEx2-3--indeed allow for prediction of the clinical progression of low-grade gliomas in adults. Our data are the first such molecular biology report regarding low-grade tumours and as such should be of help for sound decision-making. PMID:17047653

    This study explored third-grade elementary students' conceptions of nature of science (NOS) over the course of an entire school year as they participated in explicit-reflective science instruction. The Views of NOS-D (VNOS-D) was administered pre instruction, during mid-school year, and at the end of the school year to track growth in understanding over time. The Young Children's Views of Science was used to describe how students conversed about NOS among themselves. All science lessons were videotaped, student work collected, and a researcher log was maintained. Data were analyzed by a team of researchers who sorted the students into low-, medium-, and high-achieving levels of NOS understandings based on VNOS-D scores and classwork. Three representative students were selected as case studies to provide an in-depth picture of how instruction worked differentially and how understandings changed for the three levels of students. Three different learning trajectories were developed from the data describing the differences among understandings for the low-, medium-, and high-achieving students. The low-achieving student could discuss NOS ideas, the medium-achieving student discussed and wrote about NOS ideas, the high-achieving student discussed, wrote, and raised questions about NOS ideas.

    Defining the aggressiveness and growth rate of a malignant cell population is a key step in the clinical approach to treating tumor disease. The correct grading of breast cancer (BC) is a fundamental part in determining the appropriate treatment. Biological variables can make it difficult to elucidate the mechanisms underlying BC development. To identify potential markers that can be used for BC classification, we analyzed mRNAs expression profiles, gene copy numbers, microRNAs expression and their association with tumor grade in BC microarray-derived datasets. From mRNA expression results, we found that grade 2 BC is most likely a mixture of grade 1 and grade 3 that have been misclassified, being described by the gene signature of either grade 1 or grade 3. We assessed the potential of the new approach of integrating mRNA expression profile, copy number alterations, and microRNA expression levels to select a limited number of genomic BC biomarkers. The combination of mRNA profile analysis and copy number data with microRNA expression levels led to the identification of two gene signatures of 42 and 4 altered genes (FOXM1, KPNA4, H2AFV and DDX19A) respectively, the latter obtained through a meta-analytical procedure. The 42-based gene signature identifies 4 classes of up- or down-regulated microRNAs (17 microRNAs) and of their 17 target mRNA, and the 4-based genes signature identified 4 microRNAs (Hsa-miR-320d, Hsa-miR-139-5p, Hsa-miR-567 and Hsa-let-7c). These results are discussed from a biological point of view with respect to pathological features of BC. Our identified mRNAs and microRNAs were validated as prognostic factors of BC disease progression, and could potentially facilitate the implementation of assays for laboratory validation, due to their reduced number.

    We investigated the relationship between pubertal timing and deviant behaviors in Taiwan using Taiwan Youth Project (TYP) data. The TYP used multistage-stratified and class-clustered methods in 40 randomly selected schools. We analyzed 1541 adolescents (770 boys; 50.0%) who self-reported their deviant behaviors in 7th, 8th, 10th, and 12th grades. Participants were assigned to early- (n = 244; 15.8%), on-time- (n = 992; 64.4%), and late- (n = 305; 19.8%) puberty groups, and one-way analysis of variance and latent growth modeling were used to examine the frequency of deviant behaviors between them. Early-puberty adolescents had more deviant behaviors (mean = 0.43, SD = 0.74) than did late-puberty adolescents during 7th grade (mean = 0.27, SD = 0.59; p = 0.004), but not after 8th grade. There were no significant differences in the deviance level between on-time-puberty and early- and late-puberty adolescents. Moreover, puberty was not correlated with the growth of deviant behaviors, which decreased with age. However, boys seemed to engage in more deviant behaviors at the beginning, but their engagement seemed to decline faster than it did for girls. In sum, the deviance of early-puberty adolescents seemed to diminish as they got older. PMID:25956430

    Dostal, Jay Roland

    This study will evaluate alternative scheduling methods implemented in secondary level schools. Students were selected based on parent selection of programs. Traditional scheduling involves numerous academic subjects with small increments of time in each class and block scheduling focuses on fewer academic subjects and more instructional time. This study will compare office referral numbers, absence frequency, and Essential Learner Outcome (ELO) science strand scores in the 8th-grade (pretest) to the same students office referrals, absence frequency, and ELO science strand scores in the 11th-grade (posttest) between Seven Period Traditional Scheduling (SPTS) and Four Period Block Scheduling (FPBS) in the hopes that no matter what schedule students are a part of, the achievement results will be similar. (Study participants had completed both grade level ELO assessments and were continuously enrolled in one high school through their junior year.

    2016-01-01

    The objective of this study was to investigate the effects of graded levels of isomaltooligosaccharides (IMO) on the performance, immune function and intestinal microflora and intestinal mucosal morphology of weaned pigs. In a 28-day experiment, one hundred eighty, twenty eight-day-old, crossbred (Duroc×Large White×Landrace), weaned pigs, with an initial body weight of 8.19±1.45 kg, were fed either an unsupplemented corn-soybean meal based diet or similar diets supplemented with 0.2%, 0.4%, 0.6%, or 0.8% IMO added at the expense of corn. Each treatment was replicated six times with six pigs (three barrows and three gilts) per pen. From day 0 to 14, weight gain was linearly increased (p<0.05), while gain:feed (p<0.05) was linearly improved and diarrhea rate (p = 0.05) linearly declined as the IMO level increased. On d 14, the level of the immunoglobulins IgA, IgM, and IgG in the serum of pigs were linearly increased (p<0.05) with increasing IMO supplementation. Interleukin-6 (IL-6) was linearly (p<0.05) and quadratically (p<0.05) decreased as IMO intake increased. From day 15 to 28, there was a trend for weight gain to be linearly increased, and IL-2 was linearly (p<0.05) increased as IMO supplementation increased on d 28. Over the entire experiment, weight gain was linearly increased (p<0.05), while gain:feed (p<0.05) was linearly improved and diarrhea rate (p<0.05) was linearly decreased as the IMO level increased. Supplementation with IMO had no effect on the intestinal microflora of pigs in the ileum and cecum of pigs, as well as the villus height and crypt depth in the ileum and jejunum (p>0.05). These results indicate that dietary inclusion of IMO increases weight gain, gain:feed and enhanced the immune status of pigs, and could be a valuable feed additive for use in weaned pigs, particularly during the period immediately after weaning.

    Sidawi, Mai M.

    This study described how students can apply science concepts to a Design and Technology task. It also examined whether the students could transfer their scientific knowledge to their design of technology. The study was conducted at an urban school in Philadelphia where a sample of 36 eighth grade students were taught a science unit, Energy, Machines, and Motion, and engaged in a technology design task that was chosen based on the scientific content of the unit. Two approaches of relating teaching science to technological design were observed and described. Through the first approach, the students were given technology lessons in addition to their science lessons. This was to provide them with the technological knowledge that they needed in designing technology such as learning about the design process, selection of appropriate materials, and selection of appropriate tools and how to use them. Also, the students were taught the social skills that will enable them to develop an effective collaborative relationship with their peers such as conflict-management and brainstorming. Through the second approach, the students were taught the science unit and then at the end of the unit the students were given the design task as an assessment of their scientific knowledge. The students' experience of designing technology for each approach was described. The study was conducted using multiple tools and instruments such as observation, videotaping, interviews, and testing. The students were also given the survey PATT-USA to measure their attitude toward technology. The study showed that the students' learning of science was impacted by their weak prerequisite knowledge in science, their poor verbal and written communication skills and their style as dependent learners. Also, the study showed the great impact of the school and classroom cultures on the participation of the students in a Design and Technology activity. The students in this study showed great resistant to

    Canned sardines are a ready-to-use fish product with excellent nutritional properties owing to its high n-3 long-chain PUFA content, mainly EPA (20 : 5n-3) and DHA (22 : 6n-3). The present study aimed to assess the effect of two dosages of canned sardines, recommended for the primary and secondary prevention of human CVD, on the inflammatory marker concentrations and fatty acid composition of erythrocytes and key metabolic tissues (liver, muscle, adipose tissue and brain) in the rat model. Wistar rats were fed a diet containing 11 % (w/w) of canned sardines (low-sardine (LS) diet) and a diet containing 22 % (w/w) of canned sardines (high-sardine (HS) diet) for 10 weeks. Daily food intake, weight gain, and organ and final body weights were not affected by the dietary treatments. The concentrations of total cholesterol, HDL-cholesterol and LDL-cholesterol decreased in both the LS and HS groups, while those of alanine aminotransferase and adiponectin increased. The concentrations of IL-1β increased only with the highest dosage of sardine. The dose-dependent influence of the graded levels of EPA+DHA was tissue specific. Compared with that of other tissues and erythrocytes, the fatty acid composition of the brain was less affected by the canned sardine-supplemented diets. In contrast, the retroperitoneal adipose tissue was highly responsive. The deposition ratios of EPA and DHA indicated that the LS diet was optimal for DHA deposition across the tissues, except in the retroperitoneal adipose tissue. Taken together, our findings indicate that a LS diet positively affects plasma lipid profiles and inflammatory mediators, whereas a HS diet has contradictory effects on IL-1β, which, in turn, is not associated with variations in the concentrations of other pro-inflammatory cytokines. This finding requires further investigation and pathophysiological understanding. PMID:24775714

  19. A study of student attitudes toward physics and classroom environment based on gender and grade level among senior secondary education students in Indonesia

    The main purposes of the present study are to investigate the differences on student's attitudes toward physics and their perceptions regarding classroom climate during physics classes based on gender and grade level. In addition, the study also explores female students' opinions about physics, and examines to what extent this factor might influence their decision to choose or not to choose physics or physics-related fields for their career choices in the future. A group of approximately 864 male and female students, equally proportioned by gender, were assigned to take part in this study. Two standardized instruments, namely the Individualized Classroom Environment Questionnaire (ICEQ) and the Test of Science Related Attitudes (TOSRA), have been employed to collect data. A combination of quantitative and qualitative methods was used to analyze the collected data resulting from the questionnaires as well as from the interviews. The study found, first, regardless of their gender and grade level differences, students expected a more positive classroom climate during learning physics. Also, it has been found that male students experience a more positive classroom environment than female students. Second, the study found that male students do show more positive attitudes toward physics than their female counterparts. Meanwhile, twelfth-grade students show a more positive attitude toward physics than eleventh-graders. Third, the study found that most female students do not like physics based on several reasons such as physics is a hard, monotonous and boring subject. Although eleventh-grade female students do not like physics, most of them intended to choose science as their major in the next grade. Surprisingly, a majority of twelfth-grade female students who are majoring in science have no intention to choose physics or physics-related subjects either for their prospective major at the university or for their career choices in the future.

    The composition and thermodynamic properties were calculated for 100 to 110,000 K and 1.01325 x 10 to the 2nd power to 1.01325 x 10 to the 8th power N/sq m for chemical equilibrium in the Debye-Huckel and ideal-gas approximations. Quantities obtained were the concentrations of hydrogen atoms, protons, free electrons, hydrogen molecules, negative hydrogen ions, hydrogen diatomic molecular ions, and hydrogen triatomic molecular ions, and the enthalpy, entropy, average molecular weight, specific heat at constant pressure, density, and isentropic exponent. Electronically excited states of H and H2 were included. Choked, isentropic, one-dimensional nozzle flow with shifting chemical equilibrium was calculated to the Debye-Huckel and ideal-gas approximations for stagnation temperatures from 2500 to 100,000 K. The mass flow per unit throat area and the sonic flow factor were obtained. The pressure ratio, temperature, velocity, and ideal and vacuum specific impulses at the throat and for pressure ratios as low as 0.000001 downstream were found. For high temperatures at pressures approaching 1.01325 x 10 to the 8th power N/sq m, the ideal-gas approximation was found to be inadequate for calculations of composition, precise thermodynamic properties, and precise nozzle flow. The greatest discrepancy in nozzle flow occurred in the exit temperature, which was as much as 21 percent higher when the Debye-Huckel approximation was used.

    The achievement of recommended levels (≥ 30 min/day) of school moderate-to-vigorous physical activity (MVPA) is paramount to decrease risk of chronic disease in children from low-income families. The purpose of this study was to examine the predictors and grade-level trends of school day MVPA achievement in low-income children. Data were collected during the Fall of 2014 on 1232 children (Mean age = 8.8 ± 1.6 years; 625 girls, 607 boys) recruited from three low-income schools from the state of Utah in the U.S. Children wore pedometers for one school week and a stratified random subsample (n = 533) also wore accelerometers to record sedentary time and MVPA. Generalized linear mixed models were employed to calculate odds ratios for achieving school MVPA standards (≥ 30 min/day) from various predictors and to determine odds of achievement across grade levels, accounting for school and classroom clustering. Odds of meeting MVPA standards were 3 times greater if a student achieved at least 6000 steps during the school day (p < 0.01), and were 55% lower for every 1% increase in sedentary time (p < 0.001). Older children had 26% lower odds of meeting the recommended levels of MVPA compared to children in an immediately younger grade level (p < 0.05). A significant proportion of MVPA variance was explained by classroom and school affiliation (Rho = 0.09 to 0.54, p < 0.001). Daily steps, sedentary times, grade level, and classroom and school affiliation associate with school MVPA achievement in low-income children. PMID:26844162

    The impact of graded levels of day length on turkey health and behavior was determined in hens and toms raised to 18 wk of age. Birds were allocated to one of 4 lighting treatments (trt) providing 14 (14L), 17 (17L), 20 (20L), and 23 (23L) h of day length. Two time-replicated trials were completed with each, providing 2 rooms per lighting trt and each room having 3 hen (n = 720) and 3 tom (n = 480) pens. Data collection included gait score (GS), the incidence of footpad dermatitis (FPD), breast buttons and blisters, ocular size and pressure (males only), and behavioral observations (males only). Data were analyzed using SAS 9.3 based on a completely randomized design nested within 4 lighting trt. Regression analysis established relationships between response criteria and day length. Differences were considered significant at P ≤ 0.05 and trends noted at P ≤ 0.10. Gait score, FPD, and the incidence of breast buttons and blisters were assessed on 5 birds per pen at 11 and 17 wk of age. Average GS increased linearly with day length at 11 and 17 wk for both hens and toms, but the effect was larger in toms. Day length did not affect FPD, but more lesions and severe scores were found for hens than toms. The presence of breast buttons and blisters increased linearly with day length (11 wk) with the effect on blisters predominately seen in toms. Eye weight and size increased with increasing day length at 12 and 18 wk. Ocular pressure was not affected by day length. Infrared cameras recorded tom behavior over a 24 h period, and behaviors were classified over 10-min intervals using a scan sampling technique at 11 and 17 wk. Alterations in behavioral repertoire were observed with a linear increase in inactive resting and a linear decrease in standing, walking, preening, and environmental and feather pecking behaviors with increased day length. To conclude, day length affected bird mobility and incidence of breast blisters in an age- and gender-specific manner, and time

    2010-06-01

    The role of assessment in higher education is gaining importance as accountability requirements intensify and as assessments are increasingly recognized as having potential to improve teaching and learning. During the last two decades, educators have begun implementing a wider variety of assessment types including alternative and student-centered assessment practices. However, few research studies have examined the extent that college science faculty use such practices. This large-scale descriptive study utilized a nationally representative sample of higher education faculty from the US Department of Education to examine the assessment and grading practices of college science faculty from 2 and 4-year higher education institutions. When data was disaggregated by science discipline, statistically significant differences were found among physics, chemistry and biology faculty's assessment and grading practices. Biology faculty used a larger repertoire of assessment types overall, and used assessments that have potential to enhance the learning process more than chemistry and physics faculty. Physics and chemistry faculty graded on a curve more often and used competency-grading practices less often than biology faculty. Assessment practices that could be considered formative with potential to promote student learning appear to be underutilized by all science faculty.

    Although the subject of relativistic dynamics has been explored, from both classical and quantum mechanical points of view, since the work of Einstein and Dirac, its most striking development has been in the framework of quantum field theory. The very accurate calculations of spectral and scattering properties, for example, of the anomalous magnetic moment of the electron and the Lamb shift in quantum electrodynamics, and many qualitative features of the strong and electroweak interactions, demonstrate the very great power of description achieved in this framework. Yet, many fundamental questions remain to be clarified, such as the structure of classical relativistic dynamical theories on the level of Hamilton and Lagrange in Minkowski space as well as on the curved manifolds of general relativity. There moreover remains the important question of the covariant classical description of systems at high energy for which particle production effects are not large, such as discussed in Synge's book, The Relativistic Gas, and in Balescu's book on relativistic statistical mechanics. In recent years, the study of high energy plasmas and heavy ion collisions has emphasized the importance of developing the techniques of relativistic mechanics. The results of Lindner et al [Physical Review Letters 95 0040401 (2005)] as well as the more recent proposal of Palacios et al [Phys. Rev. Lett. 103 253001 (2009)] and others, have shown that there must be a quantum theory with coherence in time. Such a theory, manifestly covariant under the transformations of special relativity with an invariant evolution parameter, such as that of Stueckelberg [Helv. Phys.

    This article is a report of the 8th Berlin Workshop on Developmental Toxicity held in May 2014. The main aim of the workshop was the continuing harmonization of terminology and innovations for methodologies used in the assessment of embryo- and fetotoxic findings. The following main topics were discussed: harmonized categorization of external, skeletal, visceral and materno-fetal findings into malformations, variations and grey zone anomalies, aspects of developmental anomalies in humans and laboratory animals, and innovations for new methodologies in developmental toxicology. The application of Version 2 terminology in the DevTox database was considered as a useful improvement in the categorization of developmental anomalies. Participants concluded that initiation of a project for comparative assessments of developmental anomalies in humans and laboratory animals could support regulatory risk assessment and university-based training. Improvement of new methodological approaches for alternatives to animal testing should be triggered for a better understanding of developmental outcomes. PMID:26073002

    Strategies for the estimation of precise GPS orbits and ground baselines, designed to minimize error sources related to the GPS orbit accuracy and the tropospheric delay, are demonstrated. Using GPS data from field experiments conducted in 1985 and 1986, it is shown that, by carefully selecting well-known stations to serve as reference points and by using the GPS data to determine high-accuracy GPS orbits and to solve for wet tropospheric delay fluctuations, the 2000-km baselines in North America can now be estimated with the accuracy better than 1.5 parts in 10 to the 8th. Using these strategies, better than l-m accuracy was achieved for the two best-tracked satellites (of the seven total operational GPS satellites).
