Asimismo, se consideraron algunas variabl [...] es distales como estatus socioeconómico y tipo de colegio. En el estudio participaron 1.129 niños que cursaban 6to grado de educación primaria en Lima Metropolitana (Perú). Los estudiantes completaron cuatro pruebas: En el área de lectura fueron examinados con un subtest de la prueba Procesos Lectores (PROLEC-SE) Lectura de Palabras y Pseudo - palabras (Cuetos & Ramos, 1999). En el área de Aritmética fueron evaluados con el Subtest de Facilidad Numérica de Ekstrom, French y Harman (1979) y en el caso de Ortografía se aplicó la Prueba de Rendimiento Ortográfico (Dioses, 2001). La variable inteligencia fue medida con la Prueba de Matrices Progresivas de Raven (Raven, J., Raven, J.C. & Court, 2004). Debido a la estructura jerárquica de los datos (estudiantes dentro de clases y clases dentro de escuelas) se aplicó análisis multinivel para cada variable académica (ortografía, lectura y aritmética). Los resultados revelaron un gran impacto en primer lugar del tipo de escuela: los alumnos de escuelas privadas rindieron mejor que los de escuelas públicas en todas las áreas académicas; en segundo lugar, la variable inteligencia juega un rol esencial, cuanto mayor es el coeficiente intelectual del estudiante, mejor es el rendimiento académico, y parcialmente del género; las niñas mostraron un mejor desempeño en comparación con los niños en el área de ortografía. Se discuten en detalle algunas repercusiones pedagógicas. Abstract in english Education is in general the basis for development in any country in the world. In the education al field, several international assessments (Pisa, 2006) reflect the great gap that yet subsists among developing countries, in which the case of Peru is not an exception. There have been many national an [...] d international academic achievement evaluations that examine the skills and knowledge of students not only in Peru but also in other Latin American countries in different academic domains. One of these examples is the Regional Comparative and Explanatory Study (LLECE), in which Peru participated, in order to evaluate and compare the performance achieved by Latin American students of 3rd and 6th grade in core areas like Language, Mathematics, and Natural Sciences. Peru ranks, together with other Latin countries, with scores below the average (Regional Office for Education of UNESCO, 2008). The low ranking of the Peruvian educational system carries heavy implications and consequences, especially to the intellectual and social development of learning disabled Peruvian children. Understanding the relation between academic performance and child development is of paramount importance. The present study examines how spelling, reading and arithmetic performances are associated to various child variables (gender, intelligence, and age), and distal variables such as Socio-Economic Status (SES) or type of school. The subjects in the study were 1.129 elementary school children who were in the 6th grade (11 - 12 years old) in Metropolitan Lima, Perú. Children completed four different tests: In the reading area, the subtest of Procesos Lectores (PROLEC-SE; Cuetos & Ramos, 1999), Reading of Word and Pseudo-word; in the Arithmetic domain, the Number Facility from the Kit of Factor Referenced Cognitive Tests of Ekstrom, French, and Harman (1979) and in the spelling domain, the Spelling Achievement Test from Dioses (2001) was used. The Intelligence Quotient (IQ) was measured using Raven's Progressive Matrices Test (Raven, J., Raven, J.C., & Court, 2004, updated edition). Some preliminary analyses were conducted beforehand in order to overview and examine the structure of the data. Following this, and because of the hierarchical structure of the data (stu

    Storm Peak Laboratory (SPL) has created a place-based elementary school program, which has been implemented at five elementary schools in Northwest Colorado. Real understanding, not factual recall, is the primary goal and developing a desire to be lifelong learners in science is a secondary goal. The specific objectives of the program include the following: 1) Develop a weather and climate curriculum that teaches skills required by Colorado Student Assessment Program (CSAP). 2) Provide a hands-on place-based educational experience where students have an opportunity to use scientific equipment. 3) Provide students a three-day program that consists of an introduction, field program, and follow-up to help students grasp concepts and apply them to other school studies. 4) Provide all participating students with understanding of climate and weather 5) Build foundations for students to understand climate change. 6) Disseminate to alpine regions across the Western US, potentially impacting thousands of students that will experience the impacts of climate change during their lifetime. The SPL program spans three days for each school and includes five elementary schools. During the first day, a scientist and educators from SPL visit each classroom for two hours to introduce the concepts of climate and weather as well as teach students how to use scientific equipment. During the field program on the second day, students measure and record information about temperature, pressure, relative humidity, wind speed, and particle concentration while they travel to SPL via the gondola and chair lifts (in winter) or 4WD Suburbans (in fall). Once at the laboratory, students will meet with both SPL scientists and educators to tour the facility, discuss SPL research activities, and explore application of these activities to their curriculum. An alternative winter snowshoe program at the top of the gondola is offered to students who do not ski, where students have a program on snow science. At the end of the day each student has a data sheet with measurements recorded from 5 locations of different elevations to take back to the classroom. Following the field trip, SPL scientists and educators visit the school for a follow-up to help children grasp concepts, represent their data set collected in graphical formats, answer questions, and evaluate students" learning. Currently, approximately 250 students annually participate in the SPL 5th and 6th grade climate education program.

    The NASA-funded project, Improving 6th Grade Climate Literacy using New Media (CLINM), is designed to improve the climate literacy of California's 450,000 6th-grade students through teacher professional development that presents climate change as an engaging context for teaching earth science standards. The project fosters experience-based interaction among learners and encourages expressive creativity and idea-exchange via the web and social media. The heart of the CLINM project is the development of an online educator-friendly experience that provides content expert-reviewed, teacher-tested, standards-based educational resources, classroom activities and lessons that make meaningful connections to NASA data and images as well as new media tools (videos, web, and phone applications) based on the Green Ninja, a climate-action superhero who fights global warming by inspiring personal action (www.greenninja.info). In this session, we will discuss this approach to professional development and share a collection of teacher-tested CLINM resources. CLINM resources are grounded in earth system science; classroom activities and lessons engage students in exploration of connections between natural systems and human systems with a particular focus on how climate change relates to everyone's need for food, water, and energy. CLINM uses a team-based approach to resource development, and partners faculty in San José State University's (SJSU) colleges of Science, Education, and Humanities and the Arts with 6th-grade teachers from local school districts, a scientist from NASA Ames Research Center and climate change education projects at Stanford University, the University of Nebraska at Lincoln, and the University of Idaho. Climate scientists and other content experts identify relevant concepts and work with science educators to develop and/or refine classroom activities to elucidate those concepts; activities are piloted in pre-service science methods courses at SJSU and in teacher professional development workshops offered through the Bay Area Earth Science Institute (BAESI); workshop attendees frame the activities as lessons appropriate for their 6th grade students; participants who use the lessons and resources in their classrooms provide iterative feedback, which is used to improve the resources for other teachers involved in the project.

    Full Text Available This study aims to investigate 6th grade students’ conceptual structures about the cell concept in science education. For this purpose, drawing method, open-ended questions and word association test were applied to 65 middle school students. Descriptive analysis and content analysis were used to analyze the data. It was found that there were a wide range of alternative conceptions in students’ drawings and definitions of the cell. They mostly designated the nucleus, cell membrane and the mitochondria as the most important parts or organelles. The participants association of the cell concept with daily life was mostly categorized as ‘awareness generated by knowledge’, ‘health’ and ‘finding it necessary for the future’. Also, the data collected through the word association test was categorized under 5 categories and ‘defining the cell’, ‘parts and the organelles of the cell’ and ‘giving examples to the cell’ were the mostly persisting ones. We conclude that the 6th grade students who met for the first time with the cell concept at school had insufficient conceptions about that concept.

    Full Text Available The rapid development in technology, the effect of globalization and economical competition between countries make educational innovations necessary. In order to harmonize new generation with scientific and technological challenges, the science and technology curriculum plays crucial role. The aim of the study is to analyze new 6th grade science and technology curriculum so as to determine its main characteristics and the main differences between formal curriculum and experienced curriculum is based on analysis of formal curriculum, interviews with science and technology teachers and one observation. In this study, the researcher addresses Posner’s (1995 curriculum analysis questions through using the documents provided, and interviews with four science and technology teachers who teach in four different cities. Additionally, one observation is conducted in a class to observe the implementation of the new curriculum in real learning environment and observe the infrastructure of school. Findings show that participant teachers are satisfied with characteristics of constructivist approach in new science and technology curriculum, whereas it is stated that they have difficulty in the implementation phase. The participants mention not only inadequate lab equipment, but also difficulty in schedule of laboratories. It is also believed that participants elicit sufficient theoretical information during their pre-service education; however, they criticize the inadequate practice sessions. It is also believed that crowded classrooms are obstacles to implement a new curriculum.

    Dental trauma is an irreversible pathology which after occurrence is characterized by life long debilitating effects. The objective of the study was to measure the prevalence of trauma in anterior permanent teeth among children and associations with independent variables. A total of 453 5th and 6th grade Arab Eastern Jerusalem schoolchildren participated. Trauma, incisal overjet and lip competence were measured by one examiner in the schools. Reasons and location of trauma were assessed by telephone interviews with the parents. The total prevalence of dental trauma was 33.8%. Severe trauma prevalence (involving dentine) was 12.6%. Severe trauma was more prevalent among boys (OR = 2.03, P = 0.026); children with lip incompetence (OR = 2.71, P = 0.001); and those with an overjet of 4mm or more (OR = 3.73, P violence (20%) and playing (20%). According to the parents' reports, more fall-related injuries were reported at home, more sport injuries at school, more 'playing' injuries 'outside' (P < 0.001). Combination of results with a previous study among Jewish schoolchildren demonstrated: severe dental trauma was related to overjet (OR = 1.73, P = 0.002), lip incompetence (OR = 2.19, P < 0.001), gender (OR for males = 1.54, P = 0.005), but not to ethnicity (Arab or Jewish). The reasons for trauma observed in this study were potentially preventable. A community effort should therefore be pursued, with the aim of educating sports teachers, teachers, health personnel and schoolchildren regarding awareness of dental trauma prevention, with emphasis on utilizing mouthguards and early orthodontic intervention, when financially possible.

    This study examined associations of various elements of the home environment with after-school physical activity and sedentary time in 671 6th-grade children (Mage = 11.49 ± 0.5 years). Children's after-school total physical activity, moderate-to-vigorous physical activity, and sedentary time were measured by accelerometry. Parents completed surveys assessing elements of the home social and physical environment. Mixed-model regression analyses were used to examine the associations between each element of the home environment and children's after-school physical activity and sedentary time. Availability of home physical activity resources was associated positively with after-school total physical activity and negatively with after-school sedentary time in boys. Parental support was associated positively with after-school total physical activity and MVPA and negatively with after-school sedentary time in girls. The home physical environment was associated with boys' after-school physical activity and sedentary time, whereas the home social environment was associated with girls' after-school physical activity and sedentary time.

    Finn, Kevin Eugene

    Background: National recommendations to increase school-based physical activity and promote academic success advise incorporating movement into traditional classroom lessons. Classroom-based physical activities have favorable associations with indicators of cognitive functioning, academic behaviors, and academic achievement. Purpose: This study analyzed the Active Science framework, which incorporated school-based physical activity within interactive science classroom lessons. Specifically, the study measured the effects of the Active Science framework on student physical activity levels in the classroom, student learning of science inquiry skills and content knowledge, and student perceptions of physical activity and science. A secondary purpose was to evaluate the teachers' perceptions on the implementation of the framework. Subjects: Participants were 37 Hispanic girls (age=11.1 +/-0.8 yr) in mixed 5th/6th grade science classes in a private, urban middle school. Methods: Physical activity levels of the students during the Active Science framework were measured using pedometers and heart rate monitors. Pre- and post-tests were used to assess the levels of learning achieved by the students in science inquiry skills and content during the Active Science framework. Student perceptions and attitudes toward science and physical activity were measured during student focus groups and pre-post perception surveys. Lesson plan evaluations completed by the teachers and structured interviews provided data on implementation of the framework. Results: Physical activity results showed heart rate (146 +/-9 bpm); maximal heart rate (196 +/-10.6 bpm); time (35 +/-2.5 mins); steps (3050 +/-402.7); calories (99 +/-8.4 kcal); and distance (1.1 +/-0.2 miles) while performing the activity portion of the science lessons were consistent with national recommendations for accumulating school-based physical activity. Significant increases in science content and skills test scores with a 22.4% increase (43.9% to 66.3%; p<0.05) from pre to post (p<0.05). Students enjoyed the integration of physical activity into science lessons and the teachers described the positive effect of the framework on student interest/engagement. Conclusions: The findings from this study suggest that the Active Science framework helped to promote physical activity, facilitate student learning of science inquiry skills and content knowledge and excite students about integrating physical activity into science lessons.

METHOD: a descriptive cross-sectional convenience sample composed of 82 students, aged 11-13 years, 43 females, and 38 males in the 6th grade at a private funding school in the Metropolitan Region of Belo Horizonte. Each student responded to one form of sample characterization, performed the Academic Performance Test and was submitted to tests that evaluated the temporal auditory aspects (Duration Pattern Sequence, Pitch Pattern Sequence and Gap-in-Noise. RESULTS: the tests that assess auditory temporal aspects were not affected by the variables gender, age, music activity performance and, hand preference. The speech therapy variable was statistically significant on Gap in Noise Test. The subtests of the Educational Achievements' Test had the greatest influence on the Duration and Frequency Pattern Sequence performance were writing followed by reading and arithmetic. CONCLUSION: data analysis revealed a correlation between school performance and temporal aspects of hearing. It should be noted that the tests that evaluate the temporal ordering tasks (Frequency Pattern Sequence and Duration Pattern Sequence are influenced by the Academic Achievement Test performance. However this does not occur with the test that evaluates the temporal resolution (Gap-in-Noise.

    1979-04-01

    This study investigated the correlation among measures of perceptual-motor abilities, self-concept, and reading achievement and determined whether perceptual-motor ability and self-concept can predict reading achievement in the early elementary grades. A total of 105 boys and 108 girls from the first, and second and third grades were tested on the stabilometer, a modified Minnesota Manual Dexterity Test, a tapping test, the Primary Self-concept Inventory, and the Science Research Associates Assessment Survey. Intercorrelations across grade levels tended to be low and nonsignificant. The multiple regression procedures yielded no strong predictions of reading achievement. These findings tended to confirm the specificity of perceptual-motor ability, self-concept, and reading achievement. PMID:461046

    Full Text Available Recibido 05 de mayo de 2010 • Aceptado 31 de agosto de 2010 • Corregido 27 de junio de 2011   Resumen. La enseñanza de la lengua debe constituirse en uno de los objetivos prioritarios del sistema educativo costarricense, en consideración a su papel como herramienta de comunicación y desarrollo del pensamiento. Sin lenguaje no se puede acceder a los demás conocimientos disciplinares del currículo escolar. Una experiencia exitosa desarrollada hace algunos años con estudiantes de segundo ciclo se constituyó en la base para el diseño y ejecución de una actividad de desarrollo profesional que se implementó con el objetivo de dar a conocer, a un grupo de docentes de instituciones públicas, la estrategia integradora, previamente adaptada a los requerimientos ministeriales y a la normativa nacional vigente. El estudio se desarrolla en el marco del paradigma cualitativo y se contempla, dentro de este enfoque, la utilización de la investigación-acción y de la sistematización. Para la participación en la actividad o curso se seleccionó una muestra intencional, por factor de conveniencia, en la cual se da a conocer la estrategia que luego sería replicada con un grupo de estudiantes de zonas urbano marginales. Como técnicas se contemplaron la revisión bibliográfica, el análisis de los programas de estudio y de las normas reguladoras ministeriales, la aplicación de una entrevista a profundidad, las reflexiones de los participantes del curso contenidas en un portafolio y las del grupo de estudiantes con quienes se aplicó la estrategia.Se analizó la información teórica y reguladora mediante una triangulación, además de las apreciaciones y reflexiones de docentes y estudiantes. Se concluye sobre la necesidad de considerar un enfoque comunicativo en la enseñanza del idioma y se recomienda la estrategia desarrollada en los ambientes áulicos costarricenses que se ofrece en este artículo.  Abstract. Language teaching has become a priority in the Costa Rican educational system, considering it as a tool for communication and development of thought. Without language, there is no access to other curriculum disciplinary knowledge. A successful experience conducted some years ago, with students from 4th to 6th grade, was the basis for the design and implementation of a professional development activity addressed to promoting an integration strategy previously adjusted according to the Ministry’s requirements and the existing national regulations. This study is developed in the framework of a qualitative paradigm including research-action and systematization. A purposive sample was selected based on a suitability factor, through which individuals are informed about the strategy, and then the strategy is applied to a group of students from urban-marginal areas. The techniques used include literature review, analysis of curriculum and Ministry’s regulations, application of an in-depth interview, discussions from the course’s participant in a portfolio, and discussions from students to whom the strategy was applied. We analyzed the considerations of teachers and students, as well as the theoretical and regulatory information by triangulation. The study’s conclusion is the necessity of a communicative approach in language teaching and our recommendation is to implement the strategy developed in the Costa Rican classrooms as provided in this paper.

In 1993 the 4th LH Gray Workshop entitled ''Microbeam Probes of Cellular Radiation Response'' was held at the Gray Cancer Institute in Northwood. This was organized by Prof BD Michael, Dr M. Folkard and Dr KM Prise and brought together 40 participants interested in developing and applying new microbeam technology to problems in radiation biology (1). The workshop was an undoubted success and has spawned a series of subsequent workshops every two years. In the past, these workshops have been highly successful in bringing together groups interested in developing and applying micro-irradiation techniques to the study of cell and tissue damage by ionizing radiations. Following the first microbeam workshop, there has been a rapid growth in the number of centres developing radiobiology microbeams, or planning to do so and there are currently 15-20 worldwide. Much of the recent research using microbeams has used them to study low-dose effects and ''non-targeted'' responses such bystander effects, genomic instability and adaptive responses. The goal of the 6th workshop was to build on our knowledge of the development of microbeam approaches and the application to radiation biology in the future with the meeting stretching over a 3 day period. Over 80 participants reviewed the current state of radiobiology microbeam research worldwide and reported on new technological developments both in the fields of physics and biology.

    The integration of engineering concepts and practices into elementary science education has become an emerging concern for science educators and practitioners, alike. Moreover, how children, specifically preadolescents (grades 1-5), engage in engineering design-based learning activities may help science educators and researchers learn more about children's earliest identification with engineering. The purpose of this study was to examine the extent to which engineering identity differed among preadolescents across gender and grade, when exposing students to engineering design-based science learning activities. Five hundred fifty preadolescent participants completed the Engineering Identity Development Scale (EIDS), a recently developed measure with validity evidence that characterizes children's conceptions of engineering and potential career aspirations. Data analyses of variance among four factors (i.e., gender, grade, and group) indicated that elementary school students who engaged in the engineering design-based science learning activities demonstrated greater improvements on the EIDS subscales compared to those in the comparison group. Specifically, students in the lower grade levels showed substantial increases, while students in the higher grade levels showed decreases. Girls, regardless of grade level and participation in the engineering learning activities, showed higher scores in the academic subscale compared to boys. These findings suggest that the integration of engineering practices in the science classroom as early as grade one shows potential in fostering and sustaining student interest, participation, and self-concept in engineering and science.

    Full Text Available Using a sample of 4th and 5th graders, this study investigated whether students’ mathematics anxiety differed significantly according to a group of variables. A total of 249 students participated in the study. “The Mathematics Anxiety Scale for Elementary School Students” and “The Personal Information Form” were used for data collection. Independent samples t-tests, Oneway Anova and Schefee test were used to analyze the data. Results showed that students’ mathematics anxiety differed significantly according to gender, whether they liked mathematics class or not, whether they liked their mathematics teachers or not and the achievement level in mathematics. Female students reported significantly higher mathematics anxiety than males. Students who liked mathematics class and those who liked their mathematics teachers had lower anxiety. Students with higher achievement in mathematics reported lower degrees of mathematics anxiety. However, results did not show any significant difference in students’ mathematics anxiety with respect to their grade level and gender-stereotypes about success in mathematics.

    Full Text Available Orthographic mistake is one of the important elements leading to communication problems in written expression, and is generally one of the written expression acquisitions attempted to be taught students in educational institutions. This paper aims to reveal 6th grade students’ frequency of orthographic mistakes in their exam papers and to find out Turkish language teachers’ views about the reasons for orthographic mistakes. To do so, 336 exam papers of 6th grade students, collected both from two schools in Ad?yaman city center and a village school, have been examined. 4142 orthographic mistakes have been identified. It is seen that students do not use symbols, acronyms/abbreviations, circumflex and proper nouns, do not miswrite complementary verb conjugations, and write accurately the words formed by such sound events as vowel shortening and epenthesis. It is identified that 6th grade students have made mistakes mostly in capitalization. Moreover, writing of consonants and vowels, syncopation, the conjunction of ‘de/da’ meaning ‘also’ in English are among other most repeated mistakes. In addition, the open-ended question “What are the 6th grade students’ reasons for orthographic mistakes?” has been asked to 16 Turkish language teachers so as to find out students’ reasons for orthographic mistakes. Content analysis method has been employed to analyze the acquired data. Those Turkish language teachers have responded that the 6th grade students’ reasons for orthographic mistakes are caused by lack of interest and attention, deficiency in basic language acquisition, lack of speaking in Turkish properly and efficiently outside school, exam types or teacher’s exam evaluations, and deficiency of either teachers or students in efficient utilization of sources about orthographic rules. Besides, this paper also suggests to identify the orthographic mistakes of students other than 6th grade, present the orthographic mistakes differently and efficiently, and to explain teachers the importance of orthographic mistakes.

In this research, applied vocational group guidance program includes views and behaviours which can be measured by Apprenticeship Education Evaluation Form-B. Group discussion and homework techniques were used to gain vocational views and behaviours in vocational group guidance. After analysis there have been found significant difference between experimental and control groups’ AEEF-B pre-test post-test average scores at 0.01 level. Findings showed that vocational group guidance method had a positive effect against negative ideas to apprenticeship education. In addition, vocational group guidance method has been found to be effective in changing 8th year elementary school students’ negative views towards apprenticeship education to positive views. This program is compatible as long as it is used in vocational guidance activities of 8th year elementary school students.

Participant teachers attended one of two six week RET programs in which they worked with scientists to engage in scientific inquiry. Before and after the RETs, teachers completed the Views of Scientific Inquiry (VOSI questionnaire. Teachers’ answers were analyzed to determine the degree of sophistication of their understanding of five facets of scientific inquiry. Both elementary and secondary teacher participants showed improvement in their understanding of nature of scientific inquiry as a result of program participation, and both programs were successful in supporting the development of inquiry conceptions, although secondary science teachers started and finished the RET’s with a more sophisticated understandings of scientific inquiry. Areas of improvement for elementary teachers included the role of questions in science and the role subjectivity and creativity play in the processes of science, and for secondary teachers growth was seen in the role of questions, the relationship of data and evidence, the distinction of experiments and other means of investigations, and the varied methods of science. Implications of these results are discussed.

    Full Text Available Abstract Retroviruses and LTR-retrotransposons are widespread in all living organisms and, in some instances such as for HIV, can be a serious threat to the human health. The retroviral nucleocapsid is the inner structure of the virus where several hundred nucleocapsid protein (NC molecules coat the dimeric, genomic RNA. During the past twenty years, NC was found to play multiple roles in the viral life cycle (Fig. 1, notably during the copying of the genomic RNA into the proviral DNA by viral reverse transcriptase and integrase, and is therefore considered to be a prime target for anti-HIV therapy. The 6th NC symposium was held in the beautiful city of Amsterdam, the Netherlands, on the 20th and 21st of September 2007. All aspects of NC biology, from structure to function and to anti-HIV vaccination, were covered during this meeting.

Abstract in english Purpose to verify the prevalence of speech sound disorders (SSD) and its association to grade retention. Methods 1,810 children, randomly selected and regularly registered in the 1st grade of Elementary Public Schools have been submitted to a speech sound disorder screening test (TERDAF). Data [...] related to age and history of grade retention of the children elected to this study were collected in the school records after being authorized by children’s parents. Association between SSD and grade retention were calculated by prevalence ratio and its 95% confidence interval. Results children with SSD had more chances to grade retention when compared to those without this (PR 1.3; 95%CI: 1.1 – 1.5). The prevalence of SSD in this sample was 25%, taking into account the values of sensitivity and specificity of the screening test used. It was also verified that children with SSD have 1.3 times the risk to present history of grade retention, when compared to children without such disorders. Conclusion the prevalence of SSD when the phonological acquisition must have been established denotes that such cluster is more prevalent than what literature is used to pointing out once few population epidemiologic studies concerning human communication are carried through.

    Full Text Available Elementary education course books have been distributed free of charge by the Ministry of Education since 2005/2006 academic year. These course books are revised every year and prepared again with minor corrections. In this research, teachers were asked about their viewpoints on the final states of the course books that are revised and renewed every year. Thus, course books prepared according to the new teaching program were analyzed, aiming that the deficiencies in the books would be detected and so it would be found out how to apply the program more effectively and efficiently. Additionally, it was tried to find answers to the questions of the latest state of the books and to what extend the books would be compensating for the needs. Looking at the results of the research in general, we can conclude that elementary school teachers are mostly satisfied with the changes made in the books but teachers are not satisfied for example length of texts. And this indicates that the reviews and changes made in the books are not sufficient although they are suitable to their goals. So the reviews and changes made in the books are not sufficient although they are suitable to their goals. Beside that available teacher guidance books are insufficient in satisfying the teachers’ needs. In order to apply the program more effectively and efficiently, the teaching methods in the books should be diversified, the number of activities and their contents should be revised and the questions prepared in accordance with various goals should be reviewed.© 2013 IOJES.

    CERN Document Server

    2015-01-01

    A subject of major importance in fundamental physics is the investigation of the origin of Electroweak Symmetry Breaking. The mechanism of mass generation through the spontaneous breaking of a gauge symmetry is called the Brout-Englert-Higgs mechanism and is associated with the appearance of a physical scalar boson. The discovery announced at CERN on 4th July 2012 by the ATLAS and CMS Collaborations of a boson at a mass close to 125 GeV/c2, compatible with this scalar boson of the Standard Model, the so-called Higgs boson, mainly in ??, ZZ and WW decay modes, with compatible evidence also found at Fermilab in the bb mode, changed the landscape. This important discovery was acknowledged as decisive for the attribution of the 2013 Nobel Prize in Physics awarded jointly to François Englert and Peter Higgs . This 6th workshop of the "Higgs Hunting" series organized in Orsay on July 30th - August 1st, 2015 will discuss the developments of LHC run 1 analyses, detailed studies of the new boson and possible dev...

    The posters presented at the 6th International Immunoglobulin Symposium covered a wide range of fields and included both basic science and clinical research. From the abstracts accepted for poster presentation, 12 abstracts were selected for oral presentations in three parallel sessions on immunodeficiencies, autoimmunity and basic research. The immunodeficiency presentations dealt with novel, rare class-switch recombination (CSR) deficiencies, attenuation of adverse events following IVIg treatment, association of immunoglobulin (Ig)G trough levels and protection against acute infection in patients with X-linked agammaglobulinaemia (XLA) and common variable immunodeficiency (CVID), and the reduction of class-switched memory B cells in patients with specific antibody deficiency (SAD). The impact of intravenous immunoglobulin on fetal alloimmune thrombocytopenia, pregnancy and postpartum-related relapses in multiple sclerosis and refractory myositis, as well as experiences with subcutaneous immunoglobulin in patients with multi-focal motor neuropathy, were the topics presented in the autoimmunity session. The interaction of dendritic cell (DC)-SIGN and ?2,6-sialylated IgG Fc and its impact on human DCs, the enrichment of sialylated IgG in plasma-derived IgG, as wells as prion surveillance and monitoring of anti-measles titres in immunoglobulin products, were covered in the basic science session. In summary, the presentations illustrated the breadth of immunoglobulin therapy usage and highlighted the progress that is being made in diverse areas of basic and clinical research, extending our understanding of the mechanisms of immunoglobulin action and contributing to improved patient care.

  17. Analyzing stories told by an elementary science teacher in a fifth-grade classroom

    Science.gov (United States)

    Trotman, Alicia M.

    The purpose of this qualitative study was to analyze and interpret the stories told by one teacher, Ms. M, in a fifth grade science classroom. In this study, stories are defined as teacher utterances that are used in first person or third person narrative view, and are related to an experience that occurred outside the classroom. This research answers questions concerning: (a) what types of stories Ms. M tells during science instruction; (b) when these stories occur in the classroom; and (c) what pedagogical functions do these stories serve in the classroom. Utilizing theories on the social construction of knowledge and narrative cognition, stories told may be formed through multiple paths that follow no logical expression to make sense of the context and to connect to its audience. Therefore, this study provides insight into how Ms. M made sense of science with her stories and the ways in which they worked with her students. The results illlustrated that the types of stories found with Ms. M were autobiographical, biographical, fictional, or based on current events. These stories occurred when the teacher initiated the discussion by bringing forth a definition, a question or reinforcing a concept. However, the stories were triggered by students to a greater degree with their questions, concerns, observations or their own stories or explanations. Finally, all pedagogical functions of stories were identified with Ms. M's stories: promotion of engagement or attention of students, building community, clarifying concepts or vocabulary, activation and building of background knowledge and disclosure of teacher role and voice. Ms. M stories exemplified her sense-making of science and connections to her own life that her students were eventually able to make for themselves.

    Development of energy and environment education learning unit for upper grade of elementary school is described in this paper. A regional collaboration among elementary schools, universities and municipal governments was utilized to develop the learning unit effectively. The learning unit was proposed based on the analysis using questionnaires done to the sixth grade students in Yahaba-Higashi elementary school. The results of the analysis revel that the 78% students acquire the knowledge about energy and environment by the previous times of synthetic learning. However, the students do not have strong motivation to act for remediation of the energy and environmental circumstances, whereas they have rich-knowledge about those issues. Based on the analysis, the learning unit of energy and environment was designed with focusing to get the skill through the demonstrational experiment developed and/or arranged by academic staffs in Iwate University and in Yahaba-Higashi elementary school. The designed learning program was carried out as time of synthetic learning and was evaluated by questionnaires. The results showed the designed energy and environment learning program motivated to act locally for sustainable development.

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

    Science.gov (United States)

    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.

    Full Text Available This scientific paper is the result of the pedagogical intervention process carried out as part of teacher training in the study programs of the Basic Education Division at Universidad Nacional (Costa Rica. It aims at bringing into focus the tasks of the supervised professional practice process conducted in the study program of “Pedagogy with a specialization in the 1st to 6th grades of the Basic General Education”, from the perspective of the coordinators of this process. The coordination tasks that are essential for the development and successful completion of the professional practice process are analyzed and systematized in three main areas: coordination, induction, and conclusion of the pedagogical intervention tasks.  The opinions of students and faculty members are considered in the evaluation. One of the main contributions of this paper is calling attention to the pedagogical intervention process, which involves not only the joint preparation of a course program, but also a number of coordination strategies among the persons in charge of the pedagogical intervention to complete the process and take advantage of the practice to think carefully on the educational reality. This study has been also an opportunity of analysis and teamwork focused on continuous feedback to students and to the process itself, giving a new shape to the professional practice, and strengthening university training where the pedagogical intervention process of the Basic Education Division is a permanent research platform.

    Full Text Available This paper presents the results of analysis of educational materials for the study of Serbian language in lower-stage grades of elementary education (intended for students from 7 through 11 years old from gender perspective. The first part of the paper presents the process of institutionalization of gender-based education in the Republic of Serbia after the year 2000, when gender issues became highlighted as an integral part of the overall reform of education within the implementation of education for democracy and civil society. Declarative commitment to developing gender sensitivity has led to changes in the curriculum for elementary education and, presumably, changes in the selection of educational materials for different school subjects. The authors intended to determine whether educational materials for Serbian language honor the principle of gender equality in the selection of literary texts. The presence and nature of gender-based content in reading books from different publishers, for second and third grade, was determined by using the method of content analysis. The aim was to establish empirical evidence that would show the degree of gender sensitivity of analyzed educational materials and their compliance with the strategic commitment to gender mainstreaming in education. The authors are aware of the range of this micro-level research, and the impossibility to reach general conclusions, however, in their opinion, the obtained data may shed a light on at least one part of the mosaic of the complex relationship of education, educational material and gender equality in contemporary Serbian society. The following conclusions were drawn: (a the analyzed educational material serves the function of developing gender sensitivity; (b the principle of gender equality is respected in selection of the material; (c the distinguished gender characteristics go beyond the so-called traditional gender pattern.

    Full Text Available Abstract   Background and Aim: Reading skill is necessary for academic achievement, that deaf children have problems in this skill due to hearing impairment. Use of cochlear implant can improve auditory inputs. The aim of this study was to investigate the reading skills of children with cochlear implants and comparing that with normal ones.   Materials and Methods: This descriptive - analytic study was done on 24 children with cochlear implant and 24 normal ones that was selected from second and third grades students of Tehran primary schools. Children's reading performance was assessed by Nama reading test and the data were analyzed using T-test, linear regression and Pearson correlations.     Results: The results showed that the means of reading scores of normal children were significantly greater than the cochlear implanted ones (P<0.01. Also, there was a significant relationship between reading skills and period of cochlear implant (P<0.01.   Conclusion: Cochlear implanted children showed weaker performance in reading skills than normal ones due to less access to auditory and Phonological information. It seems that early surgery and cochlear implant before the age of language learning can be partially compensated reading defects of deaf children.   Key words: Reading skills, Cochlear implantation, Second and third grade.

    International Nuclear Information System (INIS)

    The AMES (Ageing Materials European Strategy) European network started its activity in 1993 with the aim of studying ageing mechanisms and remedial procedures for structural materials used for nuclear reactor components. Operated by JRC-IE, it has been supporting the co-ordination of the project cluster throughout the 4th and 5th EURATOM Framework Programs, carrying out projects on with plant life management implications. Among them we can list the development of non-destructive techniques applied to thermal ageing and neutron embrittlement monitoring (AMES-NDT and GRETE), improved surveillance for VVER 440 reactors (COBRA), dosimetry (AMESDOSIMETRY, MADAM and REDOS), chemical composition effects on neutron embrittlement (PISA) and advanced fracture mechanics for integrity assessment (FRAME). Main frame of the network in the 5th Framework Programme is the ATHENA project, which is aimed at summarizing the obtained achievements and edit guidelines on important issues like the Master Curve, Effect of chemical composition on embrittlement rate in RPV steels, Re-embrittlement models validation after VVER-440 annealing and open issues in embrittlement of VVER type reactors. In the 6th EURATOM Framework Programme started in 2003 the network will be part of a broader initiative on PLIM including in a more integrated way NESC, ENIQ, NET and AMALIA networks. This paper shows an overview of the concluded projects, achievements of the running ones and open issues tackled in the 6th EURATOM FWP and a summary of the plans for a new broader network on NPP Plant Life management (SAFELIFE).

    2015-04-01

    The relation of self-regulation measured prior to school entry to developing math and reading ability in prekindergarten through the second grade was examined in a prospective longitudinal sample of 1,292 children and families in predominantly rural and low-income communities in 2 regions of high poverty in the United States. Direct assessments of executive function, effortful control, and stress response physiology (indexed by resting levels of cortisol and alpha amylase obtained from saliva) were measured at child age 48 months and parents and teachers reported on children's effortful control using temperament rating scales at child age approximately 60 months. Math and reading ability, as measured by the Woodcock-Johnson III applied problems and letter-word subtests, respectively, were measured at prekindergarten through the second grade. Effects for self-regulation measures were seen primarily for initial level and to some extent growth in both mathematics and reading, even when controlling for family demographic characteristics that represent relevant selection factors into higher levels of both self-regulation and academic achievement. These effects persisted for mathematics but not for reading with the inclusion of child cognitive abilities, vocabulary, and speed of processing measured in prekindergarten, concurrent with the first time point for the academic measures. Results are interpreted as indicating a role for self-regulation in learning ability generally, likely through support for attention and reasoning abilities that are most specific to the assessment of mathematics in this analysis. Implications for instruction and for assessment and the best ways to support the development of early math and reading ability for children at risk for school failure are discussed. PMID:25688999

  6. The 6th Irradiation Test Plan of Dry Process Fuel

    International Nuclear Information System (INIS)

    The objectives of the 6th irradiation test of dry process fuel in HANARO are as follows: The first one is to establish the measurement technology of the irradiation rig. It is noted that the present experiment is the first trial of the measurement technology of the irradiation rig in remote manner. Also, it is key technology for the evaluation of the dry-process fuel performance. The second one is for obtaining the temperature measurement data through the measurement irradiation test to verify the fuel performance code with some models of material characteristics. The 6th irradiation period in HANARO is planned to be about 3 months from March 2006, and the OR5 test hole will be used. Considering the estimated average linear power and irradiation period, the discharge burnup of the 6th irradiation test is estimated to be around 1,700 MWd/tHM. Also, the preliminary safety assessment was performed for the irradiation test of dry-processed fuel at the OR5 hole of HANARO. First of all, the initial composition of dry process fuel was calculated based on the composition of selected 5 spent fuel rods estimated using their burnup history and ORIGEN-2 code. Using this result, the nuclear, thermohydraulic and mechanical characteristics of the fuel under the normal operation condition were evaluated. Under this condition the maximum linear power of dry process fuel was estimated as 64.8 kW/m, and the centerline temperature of a pellet was calculated as 2,567 .deg. C. In order to assess the integrity of the fuel under the accident condition initiated by the HANARO, safety analyses on the reactivity insertion accident and locked rotor accident were carried out. The maximum centerline temperature and cladding temperature of the fuel rod in RIA accident case were estimated 2635 .deg. C and 97 .deg. C, respectively. For the pump seizure accident, the maximum centerline temperature and cladding temperature of fuel rod were estimated 2575 .deg. C and 123 .deg. C, respectively. Considering the safety analysis results, the integrity of the fuel during the HANARO irradiation test will be secured. The irradiated dry process fuel will be transported to the IMEF. The post-irradiation examinations such as measurement of dimension, gamma scanning and microstructure analysis of pellets are planned to be performed

    Full Text Available A professional development program which trained whole school staffs in the use of positive behavioral interventions for the purpose of reducing referral rates of students for misbehavior and special education evaluation. The program focused on training teachers and paraprofessionals in behavior management strategies to increase “high approval teaching,” to develop structured and organized classroomenvironments, to engage in contingent teaching, and to improve the overall school climate. The findings suggest that training whole school staffs is an efficient way to reduce referrals for student misbehavior, to reduce the number of conduct-based referrals for special education evaluation and to impact positively on student achievement vis-à-vis reading performance. The data demonstrate that increasing on-task behavior in classrooms and reducing misbehavior results in increased student achievement. This work stresses the importance of teaching prosocial and proacademic behaviors to elementary grade students, how these behaviors are critical to school success, and the way in which school principals can provide leadership for this work.

    Full Text Available The aim of the present paper is to discuss the findings of a research study focusing on the narrative writing skills of Greek elementary school 6th grade pupils, comparing the pupils' performance before the current language teaching material was introduced, and both one and six years after its implementation. An effort was also made to explore whether the pupils' skills are influenced by gender, social background and teachers' practices regarding written discourse production. The research participants come from 10 public elementary schools. The findings of the study indicate that, already after the first year, the pupils' narrative skills display a remarkable improvement, which is even further increased after six years. It also suggests that their skills relate to their gender, social background, and current teachers' practices. Despite a general enhancement, the pupils of the sample overall display a mediocre performance.

  20. Proceeding of 6th short conference on neutron radiography

    International Nuclear Information System (INIS)

    The 6th short conference on neutron radiography was held on August 30 and 31, 1983, at the Research Reactor Institute, Kyoto niversity, as a part of the joint research program of the Institute. During the period since the first meeting in November, 1970, steady development was made in both research and practical use of neutron radiography in Japan owing to the persistent effort of the persons concerned. In the conference, 70 persons participated, and 21 papers were presented. The problems treated were the apparatuses of neutron television, neutron radiography and neutron photography, the various application of neutron radiography, the standard of neutron radiography and others. The high value of neutron radiography and the increasing demand to use this technique were shown in this meeting. Considering the recent rapid development of new technology, it is expected that neutron radiography will find the wide varieties of application in the near future. The proceedings of the conference are published by collecting the gists of papers, hoping to enhance joint effort and the exchange of information to develop neutron radiography. (Kako, I.)

    Full Text Available Abstract Background The purpose of this study was to determine the sex-specific pattern of pediatric cardiometabolic risk with principal component analysis, using several biological, behavioral and parental variables in a large cohort (n?=?2866 of 6th grade students. Methods Cardiometabolic risk components included waist circumference, fasting glucose, blood pressure, plasma triglycerides levels and HDL-cholesterol. Principal components analysis was used to determine the pattern of risk clustering and to derive a continuous aggregate score (MetScore. Stratified risk components and MetScore were analyzed for association with age, body mass index (BMI, cardiorespiratory fitness (CRF, physical activity (PA, and parental factors. Results In both boys and girls, BMI and CRF were associated with multiple risk components, and overall MetScore. Maternal smoking was associated with multiple risk components in girls and boys, as well as MetScore in boys, even after controlling for children’s BMI. Paternal family history of early cardiovascular disease (CVD and parental age were associated with increased blood pressure and MetScore for girls. Children’s PA levels, maternal history of early CVD, and paternal BMI were also indicative for various risk components, but not MetScore. Conclusions Several biological and behavioral factors were independently associated with children’s cardiometabolic disease risk, and thus represent a unique gender-specific risk profile. These data serve to bolster the independent contribution of CRF, PA, and family-oriented healthy lifestyles for improving children’s health.

    Full Text Available The idea to make a research on the use of the textbook of Geography in the first grades of theelementary school emerged from several discussions during the Course of Geography at the FaculdadeCatólica de Uberlândia-MG. The subject is controversial and there are divergences in what relatesto its importance and use by teachers. We then chose an edition for analysis which is used inseveral state public schools in Uberlândia-MG. We tried to identify and analyze the way somegeographical concepts – that are in our opinion fundamental for the understanding of thegeographical space – are approached in the textbooks. To understand the pedagogic proposal ofsome textbooks of Geography for the first grades of the elementary school it is necessary to evaluate the methodological referential used by the author - or authors - and the criteria that motivate itschoice by teachers and schools. We compared the books content that is suggested by the Secretariade Estado da Educação de Minas Gerais (Education Secretary of the State to the book content ofthe chosen edition. The objective is not to demerit the work, but to point out ways and someimportant criteria for the choice of textbooks for the first grades of the elementary school. Thisinstrument should not foment discrimination, impartiality or neutrality. It should offer elements sothat teachers and students exercise their potential and creativity on the proposed themes, as a toolto be efficiently used in classrooms.

    2014-12-01

    This study evaluated the results of a social and emotional learning (SEL) program on academic achievement among students attending a large, urban, high-risk school district. Using a cluster-randomized design, 24 elementary schools were assigned to receive either the intervention curriculum (Promoting Alternative Thinking Strategies, or PATHS) or a curriculum that delivered few if any SEL topics (i.e., the control group). In addition to state mastery test scores, demographic data, school attendance, and dosage information were obtained from 705 students who remained in the same group from the 3rd to the 6th grade. Analyses of odds ratios revealed that students enrolled in the intervention schools demonstrated higher levels of basic proficiency in reading, writing, and math at some grade levels. Although these between-groups differences held for race/ethnicity, gender, and socioeconomic status, significant within-group differences also were noted across these variables. Collectively, these findings indicated that social development instruction may be a promising approach to promote acquisition of academic proficiency, especially among youth attending high-risk school settings. Implications of these findings with respect to SEL programs conclude the article. (PsycINFO Database Record (c) 2014 APA, all rights reserved). PMID:25485463

Foram elaborados segundo os temas norteadores: promoção de práticas de letramento; conscientização sobre o uso da voz e dos níveis de ruído nas escolas; promoção de narrativas orais e escritas, envolvendo a metalinguagem e principalmente a consciência fonológica e promoção de práticas de leitura e compreensão de leitura. Ao término de cada programa, foram realizadas triagens finais, com a finalidade de analisar e comparar o desempenho dos escolares antes e após a realização dos programas. Os dados foram analisados qualitativa e quantitativamente. RESULTADOS: Houve diferenças significativas no desempenho entre as séries tanto nas triagens iniciais, quanto nas finais nas provas de ditado, leitura de palavras e frases e cloze de frases. CONCLUSÃO: A 2ª série apresentou resultados melhores do que a 1ª série. Os resultados foram mais significativos nas provas que demandaram conhecimento mais aprofundado da relação fonema-grafema e vice-versa, sugerindo que o letramento escolar é necessário quando o letramento social não se faz presente. Abstract in english PURPOSE: To investigate and compare the school literacy performance of 1st and 2nd grades elementary school individuals of a public school, before and after Reflexive Practices in Language Programs (RPLP). METHODS: Ninety-seven students of the 1st grade and 149 of the 2nd grade, between the years 20 [...] 06 and 2008, took part in this study. The subjects were submitted to school literacy screenings before and after the RPLP. The programs had an average duration of four months, and were carried out in a collective situation in classrooms, and in partnership with the teachers of the selected classes. They were prepared according to the guiding themes: promotion of literacy practices; awareness about use of voice and noise levels at school; promotion of oral and written narratives, involving meta-language and, mainly, phonological awareness and the promotion of reading practices and reading comprehension. At the end of each program, final screenings were carried out in order to analyze and compare students' performance before and after their implementation. Data were qualitatively and quantitatively analyzed. RESULTS: Significant performance differences were found between 1st and 2nd grades, in both initial and final screenings, in the subtests dictation, words and sentences reading and sentence cloze were found. CONCLUSION: Second grade had better results than first grade. The results were more significant in subtests that required deeper understanding of the phoneme-grapheme association and vice-versa, suggesting that school literacy is necessary when social literacy is not present.

METHODS: 125 students from ES were grouped according to Cycle and presence or absence of reading comprehension impairments. Two Control (good readers from both Cycles) and two Research groups (poor readers from both Cycles) were established. Assessment involved: fluency and reading comprehension; oral comprehension; working and short-term phonological memory; grammar closure. It was compared (Mann-Whitney test): in intragroup study, both Control and Research groups; in intergroup study, Control and Research from different cycles, and Control I and Research II. Spearman coefficient investigated correlations. RESULTS: Analyzing reading comprehension, we observed better performance of Control Groups in all tasks in comparison to the respective Research Groups, and better performance of Control II in comparison to Control I. Research Groups had similar results in most tests. Positive correlations have been observed between most of the variables. CONCLUSION: Students without reading comprehension impairments showed better performance in reading in both Cycles. Working memory and oral comprehension did not differentiate students with and without complaints in Cycle I, differently from what was observed in Cycle II. Research II presented similar or better performance than Research I and similar or worse performance than Control I. Underlying skills showed different profiles of correlation with reading comprehension capacity, according to the group.

O questionário usado continha 25 questões objetivas. Aplicou-se o teste de qui-quadrado e teste t, considerando a amostragem por conglomerado. Os escolares consideraram o leite materno o melhor alimento para o bebê, mas 60% optariam pela amamentação exclusiva de seus filhos. Menos de 20% responderam que a criança pode mamar até dois anos ou mais, aproximadamente ¼ acredita que o bebê deve começar a receber outros alimentos aos seis meses, e mais de 80% acredita que o consumo de chás e água é necessário. Detectaram-se as seguintes crenças: existência de leite fraco, chá é bom para cólicas, a amamentação deixa o peito caído, tamanho da mama influencia no volume de leite e a lactação deve ser interrompida com o aparecimento dos dentes. Destacaram também a participação do pai na amamentação, porém 70% relataram que ele pode ajudar dando mamadeira. Evidencia-se a necessidade de ações que promovam uma postura mais favorável à amamentação no Ensino Fundamental.The present study assessed the knowledge, perceptions, beliefs, and experiences related to breastfeeding as expressed by 564 fifth-grade students (both boys and girls. A questionnaire was used, containing 25 objective questions. The t test and chi-squared test were used, based on cluster sampling. The students consistently viewed maternal breast milk as the best food for infants, although only 60% would choose exclusive breastfeeding for their own children. Fewer than 20% replied that children could be breastfed until two years of age. Approximately one-fourth believed that infants should begin receiving other foods at 6 months of age, and 80% also believed in the need for tea and water. Other beliefs included: that breast milk is weak or thin; that tea is good for infant colic; that breastfeeding makes the breasts flaccid; that breast size influences the amount of milk; and that breastfeeding should be interrupted as soon as the infant's first teeth appear. They highlighted the importance of the father participating in the breastfeeding process, but 70% said that the father could help by giving the baby a bottle. There is also an evident need for primary schools to promote measures for a more favorable position towards breastfeeding.

    Ramsey, Whitney J.

    The purpose of this study was to determine if there were differences in standardized test scores, expressed as percentage passing, in math, reading-language arts, science, and social studies by comparing 6th grade students in K--8 schools with those in 6--8 schools. The data were gathered from an analysis of 6th grade students' scores on the 2006--2007 TCAP standardized assessment test in the state of Tennessee. The relationship between grade configuration (6--8 or K--8) and percent of 6th grade students scoring at the below proficient, proficient, or advanced level in each subject area was examined. The analysis was based on 5 research questions. A t-test for independent samples was used to identify the relationships between the independent variables, configuration of the school (K--8 or 6--8), and the dependent variables, the percent of students scoring below proficient, proficient, or advanced. A chi square analysis was used to identify the relationship between the proportion of K--8 schools meeting AYP versus the proportion of 6--8 schools meeting AYP. The study showed no relationship between grade configuration (6--8 or K--8) and percent of 6th grade students scoring at the below proficient level in math, reading-language arts, and social studies. Similarly, there was not a significant difference between grade configuration (6--8 or K--8) and percent of 6th grade students scoring at the proficient level in math and reading-language arts and the advanced level in math, reading-language arts, and science. However, there was a significant relationship between grade configuration (6--8 or K--8) and percent of 6th grade students scoring at the below proficient level and the proficient level in science and the percent of 6th grade students scoring at the proficient level and advanced level in social studies. In science, a lower percentage of 6th grade students in K--8 schools scored below proficient than did 6th grade students in 6--8 schools. In science, a higher percentage of 6th grade students in K--8 schools scored proficient than did 6th grade students in 6--8 schools. In social studies, a higher percentage of 6th grade students in K--8 schools scored proficient than did 6th grade students in 6--8 schools. However, a higher percentage of 6th grade students in 6--8 schools scored advanced than did 6th grade students in 6--8 schools. The study showed a significant difference in the proportion of K--8 schools meeting AYP versus the proportion of 6--8 schools meeting AYP.

RESULTADO: foi possível constatar que alguns escolares, tanto de 1º como de 2º ano, obtiveram desempenho inferior à média de seus grupos nas habilidades consideradas preditoras para o sucesso da leitura. Esse desempenho foi identificado a partir da porcentagem total de acertos obtida no Instrumento e a consequente classificação dos escolares em intervalos de percentis. Os grupos escolares diferenciaram-se apenas nas tarefas relacionadas às habilidades do processamento fonológico e nas competências de leitura e escrita, com melhor desempenho para os escolares do 2º ano, nas seguintes provas: (a) leitura de palavras; (b) leitura de pseudopalavras; (c) ditado de palavras; (d) ditado de pseudopalavras; (e) produção de rimas; (f) compreensão de leitura. CONCLUSÃO: a escolarização influenciou o desempenho em habilidades de processamento fonológico e competências de leitura e escrita.

Abstract in english PURPOSES: to study the performance of 1st- and 2nd-grade students of elementary school on tasks that assess abilities and skills considered as predictors of reading success. METHODS: we analyzed early reading skills in 73 children aged between six and eight years, from a public school in São Paulo. [...] The instrument used for assessing the children's early reading skills comprised of 20 subtests involving the following skills: "Oral language"; "Phonological processing"; "Comprehension"; "Reading and writing"; and "Print awareness". Data were collected and analyzed by school year (1st and 2nd grades) in order to identify differences in development at the early stages of Reading acquisition. RESULTS: it was found that the performance of some 1st- and 2nd-graders was less than average when compared to the remainder of their group on the skills considered as predictors of literacy. This low performance was identified from the percentage of total correct responses in the assessment Instrument and the classification into percentiles. There were no differences between the two grades in terms of "Oral Language" and "Print awareness". What differentiated one group from the other was their outcome at "Reading and writing" and "Phonological processing" tasks, with 2nd-grade students performing better on the following tasks: (a) word reading; (b) pseudoword reading; (c) word spelling; (d) pseudoword spelling; (e) rhyme production; and (f) reading comprehension. CONCLUSION: schooling influenced the performance on phonological processing abilities, and on reading and writing skills. Phonological processing abilities and print awareness correlated with the decoding involved in the writing and reading of isolated items.

    Amaishi, Toshirou; Fukiharu, Hiroshi

    2013-12-01

    Recently, Yoshida et al. proposed a 6th-order polynomial type 3D yield function (Yoshida model) with user friendly parameter identification scheme ([1]). This yield function has some advantages. One of the advantages is high flexibility to describe anisotropic properties. Besides, it does not need additional parameters to apply for 3D (solid) FE analysis. Authors implemented this model into commercial FEM code LS-DYNA via the user material subroutine. In this study, this yield function is applied for simulation of earing evolution of AA5042 during drawing and ironing processes and good results are obtained. As the reason for high accuracy, anisotropic properties are discussed.

  20. Irradiation experiments of the 6th-12th OGL-1 fuel assemblies

    International Nuclear Information System (INIS)

    The Oarai Gas Loop-1, OGL-1, is an in-pile helium gas loop, installed in the Japan Materials Testing Reactor (JMTR), for irradiation of high-temperature gas-cooled reactor fuels at high pressure and temperature. The present report describes results of fabrication, irradiation and post-irradiation examinations (PIE) of the 6th-12th OGL-1 fuel assemblies. The 6th-8th assemblies used coated fuel particles produced by a small-scale fluidized bed. On the other hand, the 9th-12th assemblies used trial manufacturing fuels, produced with a large-scale fluidized bed for mass production of the fuel for the High Temperature Engineering Test Reactor (HTTR) being constructed. For the 9th assembly loaded with the first mass-product fuel, the fission gas release, R/B of 88Kr, was relatively high, 1.5x10-5, and various defects were observed in the ceramography of the irradiated coating layers. Afterwards, a decrease was achieved in the through-coating failure fractions at the fabrication. Correspondingly, the R/B of 88Kr for the 12th assembly was reduced to an excellent value of 2x10-6. Thus, the production technology and the irradiation performance of the HTTR design fuels were successfully demonstrated. (author)

  1. Possible earthquake trigger for 6th century mass wasting deposit at Lake Ohrid (Macedonia/Albania)

    Lake Ohrid shared by the Republics of Albania and Macedonia is formed by a tectonically active graben within the south Balkans and suggested to be the oldest lake in Europe. Several studies have shown that the lake provides a valuable record of climatic and environmental changes and a distal tephrostratigraphic record of volcanic eruptions from Italy. Fault structures identified in seismic data demonstrate that sediments have also the potential to record tectonic activity in the region. Here, we provide an example of linking seismic and sedimentological information with tectonic activity and historical documents. Historical documents indicate that a major earthquake destroyed the city of Lychnidus (today: city of Ohrid) in the early 6th century AD. Multichannel seismic profiles, parametric sediment echosounder profiles, and a 10.08 m long sediment record from the western part of the lake indicate a 2 m thick mass wasting deposit, which is tentatively correlated with this earthquake. The mass wasting deposit is chronologically well constrained, as it directly overlays the AD 472/AD 512 tephra. Moreover, radiocarbon dates and cross correlation with other sediment sequences with similar geochemical characteristics of the Holocene indicate that the mass wasting event took place prior to the onset of the Medieval Warm Period, and is attributed it to one of the known earthquakes in the region in the early 6th century AD.

    Evaluation of bone mineral density (BMD) of the ancient peoples has received great interest by anthropologists. The aims of this study are to investigate the lumbar vertebrae of the Iasos people during the Byzantine period, in order to determine the prevalence of bone loss and to interpret dietary conditions of ancient Mediterranean populations. Lumbar vertebrae belonging to twenty eight skeletons of the 6th c AD were analyzed by radiographs and dual energy X-ray absorptiometry. The BMD values for each biologic sex and age group were compared. The correlation between the BMD and radiological features was also analyzed. The mean BMD was 0.940 g/cm2. BMD was decreased by aging in both sexes, but it was not significant. Osteopenia was found in 11 (39%) and osteoporosis in 4 (14.3%) out 28 vertebrae. The BMD was normal in 13 (46%) out of 28 vertebrae. Osteopenia was present in 7 (38%) of 18 male vertebrae and 4 (40%) of 10 female vertebrae. The spine score was high in the male group and there was a strong positive correlation between the BMD and spine score for both sexes. This study revealed that the BMD decreased by aging and that osteopenia was a problem in both sexes of the Iasos people during the 6th c AD. There was no correlation between the BMD and radiological features for age groups and biological sexes.

    2004-01-01

    Full Text Available In recent years, we have witnessed an increasing research interest in children’s writing ability in various genres, used in their specific cultures. Argumentative writing commands a considerable part of this research for several reasons, including the relationship of argument to the cognitive development and critical thinking as well as the difficulty of constructing an argumentative text. The latter was evident in a recent study by this author concerning the quality of argumentative texts written by students of 4th and 6th grade in a number of Greek primary schools. The present research investigates and compares the quality of children’s argumentative writing before intervention, with the quality of the writing after instruction with specifically prepared lessons about Human Rights. These lessons indirectly teach argumentative writing. Method: Qualitative and quantitative analysis with various measures enabled researchers to compare written argumentative texts before intervention with those produced after Human Rights teaching of 19 ten-year-old Greek students in one elementary school. The results show that the ability to construct argumentative texts is considerably enhanced through the indirect teaching used as learning scaffold.

    Full Text Available Neste artigo são estudadas as estratégias e representações usadas por alunos turcos de diferentes séries (da 6ª a 8ª) quando resolvendo problemas que envolvem a busca de padrões lineares e quadráticos. Os dados foram coletados a partir da aplicação de testes específicos em 246 alunos e de entrevista [...] s clínicas com 18 desses alunos. Os resultados apontam que a eficácia nos padrões de generalização aumentam positivamente de uma série escolar para outra, bem como aumenta a variedade das estratégias de generalização. Enquanto alunos de diferentes momentos da escolarização usam estratégias recursivas para resolver os problemas relativos à busca de padrões, mas a quantidade de estudantes que mobilizam estratégias explícitas é relativamente pequena. Alunos de séries mais avançadas usam vários tipos de representações no processo de generalizar, ao passo que alunos das séries mais iniciais, de modo acentuado, preferem a representação numérica. Abstract in english The study aims to compare and determine 6th-8th graders' efficiencies, strategies and representations of student from different grades (from 6th to 8th) when dealing with problems related to linear and quadratic patterns. Research data was obtained from tests applied to 246 students and clinical int [...] erviews implemented with 18 students. It was shown that when grade increases students' efficiencies of generalizing pattern improve in a positive way in all levels. Besides this, as learning levels of 6th and 8th grade students increase, the variety in pattern generalization strategies changed at least in all types of patterns. While students at different learning levels generally used recursive strategy to solve all the problems, the number of the students using explicit strategies is relatively low. The students of high levels use many types of representation in generalization; in contrast, the weak level students prefer mostly numerical representations.

In relation to the teaching materials, the genres that are exploited both for reading and writing, as well as the topics and the volume of written material made available should be object of reflection

  10. 6th conference of German judges at administrative courts held at Kassel

    International Nuclear Information System (INIS)

    In nine working groups, the 6th conference of German judges at administrative courts, held at the beginning of May 1980, primarily dealt with the question as to where the limits are set to legal protection by administrative courts, and with the further creation of public law by judges at administrative courts. Working group No. I turned to the control of decisions made during legal proceedings at administrative courts concerning the Federal Act for Protection against Nuisances and the Atomic Energy Law. In doing so, they dealt especially with the decisions on Kalkar and Muelheim-Kaerlich, made by the Federal Constitutional Court. This working group came to the result that hand in hand with a cutdown of the judicial intensity of control we will further observe legal protection shifting into the field of administrative proceedings.

  13. Uranium groundwater anomalies and L'Aquila earthquake, 6th April 2009 (Italy)

    International Nuclear Information System (INIS)

    Monitoring of chemical and physical groundwater parameters has been carried out worldwide in seismogenic areas with the aim to test possible correlations between their spatial and temporal variations and strain processes. Uranium (U) groundwater anomalies were observed during the preparation phases of the recent L'Aquila earthquake of 6th April 2009 in the cataclastic rocks near the overthrust fault crossing the deep underground Gran Sasso National Laboratory. The results suggest that U may be used as a potential strain indicator of geodynamic processes occurring before the seismic swarm and the main earthquake shock. Moreover, this justifies the different radon patterns before and after the main shock: the radon releases during and after the earthquake are much than more during the preparatory period because the process does not include only the microfracturing induced by stress-strain activation, but also radon increases accompanying groundwater U anomalies.

    The present aerospace engineering and science workforce is ageing. It is not clear that the US education system will produce enough qualified replacements to meet the need in the near future. Unfortunately, by the time many students get to high school, it is often too late to get them pointed toward an engineering or science career. Since some college programs require 6 units of high school mathematics for admission, students need to begin consciously preparing for a science or engineering curriculum as early as 6th or 7th grade. The challenge for educators is to convince elementary school students that science and engineering are both exciting, relevant and accessible career paths. This paper describes a program designed to help provide some excitement and relevance. It is based on the task of developing a mobile robot or "Rover" to explore the surface of Mars. There are two components to the program, a curriculum unit and a contest. The curriculum unit is structured as a 6-week planetary science unit for elementary school (grades 3-5). It can also be used as a curriculum unit, enrichment program or extracurricular activity in grades 6-8 by increasing the expected level of scientific sophistication in the mission design. The second component is a citywide competition to select the most outstanding models that is held annually at a local college or University. Primary (Grades 3-5) and middle school (Grades 6-8) students interested in science and engineering will design and build of a model of a Mars Rover to carry out a specific science mission on the surface of Mars. The students will build the models as part of a 6-week Fall semester classroom-learning or homework project on Mars. The students will be given design criteria for a rover, and be required to do basic research on Mars that will determine the operational objectives and structural features of their rover. This module may be used as part of a class studying general science, earth science, solar system astronomy or robotics or as a multi-disciplinary unit for a gifted and talented program. A written report on the science objectives and design features of the Rover is required. The program includes specific learning objectives in research skills, language arts (reading scientific literature, preparing a verbal presentation and writing a report), mathematics, science and engineering.The model will be mostly a mock-up, constructed at a minimal cost (estimated cost of less than 10-25) of mostly found objects and simple art supplies.

    Shenandoah Elementary School is a rural educational facility located in the farmlands of Indiana. The Elementary Science Enrichment Program was established to create a learning atmosphere that encourages scientific thinking and problem-solving. Its inception was founded on the belief that the concepts and process skills inherent in the teaching of science are critical to the early intellectual development of elementary students. The program was established through speaking engagements at the local and state level which resulted in the necessary support to insure its continuation. All students in grades K-5 meet for weekly science activities in our elementary lab to investigate many exciting curricular areas including planaria regeneration, star life cycles, and acid rain telecommunications. This allows for in-depth exploration of the science process skills which culminate in a variety of products including student portfolios, hands-on assessments, simulations and global data communications. These activities are extended through family science and the modeling of science instructional techniques for classroom educators.

  7. NFAP calculation of pressure response of 1/6th scale model containment structure

    International Nuclear Information System (INIS)

    The details associated with the NFAP calculation of the pressure response of the 1/6th scale model containment structure are discussed in this paper. Comparisons are presented of some of the primary items of interest with those determined from the experiment. It was found from this comparison that the hoop response of the containment wall was adequately predicted by the NFAP finite element calculation, including the response in the high pressure, high strain range at which cracking of the concrete and yielding of the hoop reinforcement occurred. In the vertical or meridional direction, it was found that the model was significantly softer than predicted by the finite element calculation; that is, the vertical strains in the test were three to four times larger than computed in the NFAP calculation. These differences were noted even at low strain levels at which the concrete would not be expected to be cracked under tensile loadings. Simplified calculations for the containment indicate that the vertical stiffness of the wall is similar to that which would be determined by assuming the concrete fully cracked. Thus, the experiment indicates an anomalous behavior in the vertical direction

    During July to November, 2006, an important archaeological excavation was conducted in Yun country, Hubei province, southern China. Chinese archaeologists found some remnant of leather materials, covered with red pigments, on a 6th century B.C. Chinese bronze sword. To understand the technology/ies that may have been utilized for manufacturing the leathers, a combined of Raman spectroscopy, FT-IR and XRF was thus applied to the remnant of leather materials. Raman analyses showed that red pigment on the leather was cinnabar (HgS). FT-IR and XRF analyses indicated that the content of some elements, such as Ca (existing as CaCO 3) and Fe (existing as Fe 2O 3), were much higher than those in the surrounding grave soil. The results inferred an application of lime depilation and retting, and the Fe-Al compound salt as tanning agent. And it was furthermore implicated that the Fe-Al salt tanning technique had been developed in the middle and late Spring and Autumn Period of China.

  10. Rapid landscape change in 6th century Jordan: driven by climate or man-made?

    Science.gov (United States)

    Lucke, Bernhard

    2014-05-01

    Compared to the rich cities of antiquity, many areas in the Levant appear today degraded. European travel reports of the 19th century and excavations in Jordan created the impression that population numbers were strongly reduced during the Islamic periods, leading to 'empty' lands which were only resettled during the early 20th century. However, our case study near the ancient site Abila of the Decapolis in northern Jordan found that the land was probably never 'empty' and always fertile - but valley fills provide evidence for a rapid and intense landscape change during the Late Byzantine period. This was probably caused by a significant shift to aridity which also triggered socio-economic changes of subsistence strategies from agriculture to pastoralism. The dates of sediments which are available so far indicate that the climatic change seemingly occurred rapidly within approximately 100 years during the late 6th and early 7th century AD, and rubble layers let it seem probable that it was associated with frequent heavy rainfall events. It might have been caused or triggered by a global climate event creating the "year without sun" or 'Mystery Veil' which the Byzantine historian Procopius described in the year 536 AD. If similar events repeat under the current climate change, it will be difficult to mitigate them.

    Full Text Available Abstract The 6th annual Cancer Vaccines and Immunotherapy Colloquium at Walker's Cay was held under the auspices of the Albert B. Sabin Vaccine Institute on March 10–13, 2004. The Colloquium consisted of a select group of 34 scientists representing academia, biotechnology and pharmaceutical industry. The main goal of this gathering was to promote in a peaceful and comfortable environment exchanges between basic and clinical science. The secondary benefit was to inspire novel bench to bedside ventures and at the same time provide feed back about promising and/or disappointing clinical results that could help re-frame some scientific question or guide the design of future trials. Several topics were covered that included tumor antigen discovery and validation, platforms for vaccine development, tolerance, immune suppression and tumor escape mechanisms, adoptive T cell therapy and dendritic cell-based therapies, clinical trials and assessment of response. Here we report salient points raised by speakers or by the audience during animated discussion that followed each individual presentation.

    International Nuclear Information System (INIS)

    It has been recognized that neutron diffraction is an important means of research which can obtain the information on the positions of hydrogen atoms and water molecules which bear important roles in physiological functions, but due to the shortage of the diffractometers that give sufficient diffraction intensity, the utilization has not advanced. By the improvement of neutron flux due to the realization of the JRR-3M and the recent remarkable progress of biochemistry and biophysics, the structural analysis at atomic and molecular levels of the matters of living bodies and the elucidation of physiological functions have become to be carried out. The neutron diffractometer for the matters of living bodies aims at the top class in the world, and has been discussed by the experts in the world in five workshops. As the result, the neutron diffractometer was constructed, and the Gragg reflection from the single crystal of lysozyme protein was successfully observed for the first time in Japan. The 6th workshop was held on March 25, 1995 at Japan Atomic Energy Research Institute, and the lecture by Dr. B.P. Schoenborn was given, and the examples of the application of neutron imaging plates were reported. The important contents of the publications are summarized in this report. (K.I.)

  10. The effects of the science writing heuristic (SWH) approach versus traditional instruction on yearly critical thinking gain scores in grade 5-8 classrooms

    Science.gov (United States)

    Tseng, Ching-mei

    Critical Thinking has been identified in the Common Core State Standards (CCSS) and Next Generation Science Standards (NGSS) as skills needed to prepare students for advanced education and the future workforce. In science education, argument-based inquiry (ABI) has been proposed as one way to improve critical thinking. The purpose of the current study was to examine the possible effects of the Science Writing Heuristic (SWH) approach, an immersion argument-based inquiry approach to learning science, on students' critical thinking skills. Guided by a question-claims-evidence structure, students who participated in SWH approach were required to negotiate meaning and construct arguments using writing as a tool throughout the scientific investigation process. Students in the control groups learned science in traditional classroom settings. Data from five data sets that included 4417 students were analyzed cross-sectionally and longitudinally. Yearly critical thinking gain scores, as measured by Form X of Cornell Critical Thinking Test, were compared for students who experienced the SWH approach versus students who experienced traditional instruction in both elementary (5th grade) and secondary schools (6th-8th grades). Analyses of yearly gain scores for data sets that represented a single year of implementation yielded statistically significant differences favoring SWH over traditional instruction in all instances and statistically significant interactions between gender and grade level in most instances. The interactions revealed that females had higher gain scores than males at lower grade levels but the reverse was true at higher grade levels. Analyses from data sets that included two years of implementation revealed higher overall gains for SWH instruction than for traditional instruction but most of those gains were achieved during the first year of implementation. Implications of these results for teaching critical thinking skills in science classrooms are discussed in detail.

    Although glufosinate ammonium herbicides are considered safe when used properly, ingestion of the undiluted form can cause grave outcomes. Recently, we treated a 34-yr-old man who ingested glufosinate ammonium herbicide. In the course of treatment, the patient developed apnea, mental deterioration, and sixth cranial nerve palsy; he has since been discharged with full recovery after intensive care. This case report describes the clinical features of glufosinate intoxication with a focus on sixth cranial nerve palsy. Our observation suggests that neurologic manifestations after ingestion of a "low-grade toxicity herbicide" are variable and more complex than that was previously considered. PMID:24265537

    2008-07-01

    The 6th International Conference on Inverse Problems in Engineering: Theory and Practice (ICIPE 2008) belongs to a successful series of conferences held up to now following a three-year cycle. Previous conferences took place in Palm Coast, Florida, USA (1993), Le Croisic, France (1996), Port Ludlow, Washington, USA (1999), Angra dos Reis, Brazil (2002), and Cambridge, UK (2005). The conference has its roots on the informal seminars organized by Professor J V Beck at Michigan State University, which were initiated in 1987. The organization of this Conference, which took place in Dourdan (Paris) France, 15-19 June 2008, was made possible through a joint effort by four research departments from four different universities: LEMTA (Laboratoire de Mécanique Théorique et Appliquée, Nancy-Université) LMS (Laboratoire de Mécanique des Solides, Ecole Polytechnique, Paris) LMAC (Laboratoire de Mathématiques Appliquées, UTC Compiègne) LTN (Laboratoire de Thermocinétique, Université de Nantes) It received support from three organizations: SFT (Société Française de Thermique: French Heat Transfer Association) ACSM (Association Calcul de Structures et Simulation : Computational Structural Mechanics Association) GdR Ondes - CNRS (`Waves' Network, French National Center for Scientific Research) The objective of the conference was to provide the opportunity for interaction and cross-fertilization between designers of inverse methods and practitioners. The delegates came from very different fields, such as applied mathematics, heat transfer, solid mechanics, tomography.... Consequently the sessions were organised along mostly methodological topics in order to facilitate interaction among participants who might not meet otherwise. The present proceedings, published in the Journal of Physics: Conference Series, gathers the four plenary invited lectures and the full-length versions of 103 presentations. The latter have been reviewed by the scientific committee (see composition below) and additional reviewers we wish to thank here for their kind help. Among the 194 abstracts initially received, 121 communications have been accepted for presentation, 109 of which having been actually presented (oral or poster form) at the conference, as well as 4 invited plenary lectures. The presentations for each session topic, and the geographic distribution of the delegates, are given in tables below. It is our hope that ICIPE 2008 has contributed to maintaining existing interactions and fostering new ones. We take this opportunity to thank all the authors for their valuable contributions and the excellent atmosphere of the meeting. The next ICIPE conference is planned to take place in the USA in May 2010. It will be organized by Alain J Kassab of the University of Central Florida (UCF) in Orlando, and will take place on the UCF campus. Further details regarding ICIPE 2010 conference will be made available on the ICIPE 2008 website during the fall of 2008, and will also be disseminated directly to individuals having attended previous ICIPE meetings.

    Full Text Available Dear Colleagues!We are glad to present the 6th Edition of Standards of Diabetes Care. These evidence-based guidelines were designed to standardize and facilitate diabetes care in all regions of the Russian Federation. The Standards are updated on the regular basis to incorporate new data and relevant recommendations from national and international clinical societies, including World Health Organization Guidelines (WHO, 2011, International Diabetes Federation (IDF, 2011, American Diabetes Association (ADA, 2013, American Association of Clinical Endocrinologists (AACE, 2009, International Society for Pediatric and Adolescent Diabetes (ISPAD, 2009 and Russian Association of Endocrinologists (RAE, 2011, 2012. Current edition of the “Standards” also integrates results of completed randomized clinical trials (ADVANCE, ACCORD, VADT, UKPDS, etc., as well as findings from the national studies of diabetes mellitus (DM, conducted in close partnership with a number of Russian hospitals.Latest data indicates that prevalence of DM increased during the last decade more than two-fold, reaching some 371 million patients by 2013. According to the current estimation by the International Diabetes Federation, every tenth inhabitant of the planet will be suffering from DM by 2030. These observations resulted in the UN Resolution 61/225 passed on 20.12.2006 that encouraged all Member States “to develop national policies for the prevention, treatment and care of diabetes”.Like many other countries, Russian Federation experiences a sharp rise in the prevalence of DM. According to Russian State Diabetes Register, there are at least 3.799 million patients with DM in this country. However, the epidemiological survey conducted by the Federal Endocrinology Research Centre during 2002-2010 suggests that actual prevalence is 3 to 4 times greater than the officially recognized and, by this estimate, amounts to 9-10 million persons, comprising 7% of the national population. Severe consequences of the global pandemics of DM include its vascular complications: nephropathy, retinopathy, coronary, cerebral and peripheral vascular disease. These conditions are responsible for the majority of cases of diabetes-related disability and death. Current edition of the “Standards” emphasizes the patient-oriented approach in making decisions on therapeutic goals, such as levels of glycaemia and blood pressure. It also features updated guidelines on the management of vascular complications and new RAE position statement on gestational diabetes, produced in collaboration with Russian Association of Obstetrics and Gynecology. This text represents a consensus by the absolute majority of national experts, achieved through a number of fruitful discussions held at national meetings and forums. These guidelines are intended for endocrinologists and diabetologists, primary care physicians, cardiologists and other medical professionals involved in prevention and treatment of diabetes mellitus.

    Many science "museums” already offer fantastic programs for the general public, and even some aimed at elementary school kids. However, these venues are usually located in large cities and are only occasionally used as tools for enriching science education in public schools. Here we present preliminary work to establish exciting educational enrichment environments for public schools that do not easily have access to such facilities. This program is aimed at motivating children's interest in science beyond what they learn in the classroom setting. In this program, we use the experience and experiments/demonstrations developed at a large science museum (in this case, The St. Louis Science Center) and take them into a local elementary school. At the same time, students from the University of Missouri are getting trained on how to present these outreach materials and work with the local elementary schools. Our pilot study has started with implementation of presentations/demonstrations at Benton Elementary School within the Columbia Public School district, Missouri. The school has recently adopted a STEM (Science, Technology, Engineering, and Mathematics) centered learning system throughout all grade levels (K-5), and is therefore receptive to this effort. We have implemented a program in which we have given a series of scientific demonstrations at each grade level's lunch hour. Further enrichment ideas and plans include: addition demonstrations, hands-on experiments, and question and answer sessions. However, the application of these events would be to compliment the curriculum for the appropriate grade level at that time. The focus of this project is to develop public communications which links science museums, college students and local public schools with an emphasis on encouraging college science majors to share their knowledge and to strengthen their ability to work in a public environment.

  17. Solution of the 6th dynamic AER benchmark using the coupled core DYN3D/ATHLET

    International Nuclear Information System (INIS)

    The 6th dynamic benchmark is a logical continuation of the work to validate systematically coupled neutron kinetics/thermohydraulics code systems for the estimation of the transient behaviour of WWER type nuclear power plant which was started in the 5th dynamic benchmark. This benchmark concerns a double ended break of the main steam line (asymmetrical MSLB) in a WWER plant. The core is at the end of first cycle in full power conditions. The asymmetric leak causes a different depressurization of all steam generators. New features in comparison to the 5th dynamic benchmark were included: asymmetric operation of the feed water system, consideration of incomplete coolant mixing in the reactor vessel, and the definition of a fixed isothermal recriticality temperature for normalising the nuclear data (Authors)

  18. The b value before the 6th August, 1988 India-Myanmar Border Region Earthquake—a case study

    Sahu, O. P.; Saikia, M. M.

    1994-07-01

    Smith (1981, 1986) and Wyss et al. (1990) have observed that intermediate-term quiescence is often associated with an increasing b value. This study pertains to the temporal behaviour of the b value before the earthquake of 6th August, 1988, which occurred in the India-Myanmar border region. The b value in the preparation zone of the earthquake (21°-25.5°N, 93°-96°E), as identified by Gupta and Singh (1986, 1989), is found to have increased gradually from 1976 to a maximum value of 1.33 during July, 1987, followed by a short-term drop before the occurrence of the earthquake. The quiescence period observed by Gupta and Singh (1986, 1989) for this earthquake is better reflected by the intermediate-term increase in the b-value. A drop in the mean magnitude since 1978 is supported by a CUSUM plot.

  20. Finite-Difference Approach for a 6th-Order Nonlinear Phase Equation with Self-Excitation

    Science.gov (United States)

    Mohammed, Mayada; Strunin, Dmitry

    A range of physical systems, particularly of chemical nature involving reactions, perform self-excited oscillations coupled by diffusion. The role of diffusion is not trivial so that initial differences in the phase of the oscillations between different points in space do not necessarily disappear as time goes; they may self-sustain. The dynamics of the phase depend on the values of the controlling parameters of the system. We consider a 6th-order nonlinear partial differential equation resulting insuch dynamics. The equation is solved using central finite-difference discretization in space. The resulting system of ordinary differential equations is integrated in time using a Matlab solver. The numerical code is tested using forced versions of the equation, which admit exact analytical solutions. The comparison of the exact and numerical solutions demonstrates satisfactory agreement.

  1. Proceedings of 6th International Microbeam Workshop/12th L.H. Gray Workshop Microbeam Probes of Cellular Radiation Response

    International Nuclear Information System (INIS)

    The extended abstracts which are submitted here present a summary of the proceedings of the 6th International Workshop/12th LH Gray Workshop: Microbeam Probes of Cellular Radiation Response, held at St. Catherine's College, University of Oxford, UK on March, 29th-31st, 2003. In 1993 the 4th LH Gray Workshop entitled ''Microbeam Probes of Cellular Radiation Response'' was held at the Gray Cancer Institute in Northwood. This was organized by Prof BD Michael, Dr M. Folkard and Dr KM Prise and brought together 40 participants interested in developing and applying new microbeam technology to problems in radiation biology (1). The workshop was an undoubted success and has spawned a series of subsequent workshops every two years. In the past, these workshops have been highly successful in bringing together groups interested in developing and applying micro-irradiation techniques to the study of cell and tissue damage by ionizing radiations. Following the first microbeam workshop, there has been a rapid growth in the number of centres developing radiobiology microbeams, or planning to do so and there are currently 15-20 worldwide. Much of the recent research using microbeams has used them to study low-dose effects and ''non-targeted'' responses such bystander effects, genomic instability and adaptive responses. The goal of the 6th workshop was to build on our knowledge of the development of microbeam approaches and the application to radiation biology in the future with the meeting stretching over a 3 day period. Over 80 participants reviewed the current state of radiobiology microbeam research worldwide and reported on new technological developments both in the fields of physics and biology

    Lin, Wei; Yang, Hsiao-Chi; Hang, Chi-Ming; Pan, Wen-Harn

    2007-01-01

    The purpose of this study is to understand nutrition knowledge, attitude, and behavior in Taiwanese elementary school children, and the relationship of these various components. The results indicated that children's knowledge was fair in nutrition basics, but poor in 'the physiological function of nutrients', 'relationships between diet/nutrients and disease', and 'the daily serving requirement for different food groups'. Children in general valued the importance of nutrition, but they did not concern the health benefit of foods in food selections. Their dietary quality was not satisfactory, and the diet of most children did not meet the recommended serving requirements for milk, vegetable, fruit, and cereals and grains groups. Positive relationships were found among nutrition knowledge, attitude, caring- about-nutrition behavior and dietary quality score. The restraint or disinhibited eating behavior of 4th to 6th graders was not serious, but a large number of children already performed some self-controlling practices to avoid obesity, but not frequently. One fourth of the students skipped meals, especially breakfast, and one quarter of 4th to 6th graders prepared their own breakfast; which may have some impact on children's diet quality. A gap was found between nutrition knowledge, attitude and eating behavior, especially vegetable and fruit consumption, indicating that the attitude toward eating for health was not strong in this age group. Future nutrition education for school children should not only include food serving requirements of food groups, but also apply appropriate theories to improve the motivation for healthy eating.

  11. A curriculum strategy that expands time for in-depth elementary science instruction by using science-based reading strategies: Effects of a year-long study in grade four

    Science.gov (United States)

    Romance, Nancy R.; Vitale, Michael R.

    An integrative curriculum strategy emphasizing science process skills and hands-on activities expanded the time allocated for in-depth science instruction by replacing a district-adopted basal reading program with science-content reading designed to facilitate applied comprehension skills. This study investigated the combined effect of these curricular components (i.e., in-depth science, science-content-based reading) upon student achievement, attitudes, and self-confidence in both science and reading over the school year. In doing so, teachers in three fourth-grade classrooms each incorporated applied reading (and language arts) objectives into science reading activities as part of a daily, expanded, in-depth science teaching block that encompassed the total instructional time originally allocated to reading and science. Using multivariate covariance analysis, results showed that the students in the experimental group, compared to demographically similar controls, not only displayed significantly greater standardized test achievement as measured by the Iowa Tests of Basic Skills reading subtest and the Metropolitan Achievement Test science subtest, but also displayed a more positive attitude toward science and reading and greater self-confidence in learning science. Implications of the strategy for future curriculum research in science education are discussed.

    Full Text Available Este estudo buscou caracterizar as práticas e identificar representações sociais de escolares sobre o futebol no âmbito da aulas de Educação Física Escolar. Trata-se de uma pesquisa qualitativa de tipo etnográfico, que utilizou observação participante e entrevistas semiestruturadas, além de question [...] ário, em uma turma de 29 alunos do 6º ano do Ensino Fundamental, em uma escola pública na cidade de Bauru - SP. Os resultados indicam que as mídias e a família são os principais elementos que constituem as representações dos alunos sobre o futebol, e que o modo como a prática do futebol é desenvolvida na escola ao mesmo tempo as constrói e realimenta. Concluímos que as representações sociais são um importante meio que orienta as relações dos alunos com o futebol, na medida em que influenciam a orientação e organização das suas condutas. Todavia, isto não torna homogêneas suas condutas e valores, pois os alunos buscam no futebol a satisfação de algo que é também pessoal, como diversão e amizades. Abstract in english This study aimed to characterize the practices and social representations of students about football within the Physical Education classes. This is a qualitative research of ethnographic type, which used participant observation and semi-structured interviews, as well as questionnaires, in a class of [...] 29 students from 6th grade of Elementary Education, in a private school in Bauru City-SP. The results indicate that the media and the family are the main elements that constitute the representations of students about football, and that the way football practice is developed at school simultaneously builds and feed them. We conclude that social representations rule the relationships of students with football, insofar as they guide and organize their behavior. However, this does not make their conduct and values homogenous, because the students seek in football the satisfaction of something that is also personal, as fun and friendship.

  20. Modeling of Synergy Between 4th and 6th Harmonic Absorptions of Fast Waves on Injected Beams in DIII-D Tokamak

    International Nuclear Information System (INIS)

    In recent moderate to high harmonic fast wave heating and current drive experiments in DIII-D, a synergy effect was observed when the 6th harmonic 90 MHz fast wave power is applied to the plasma preheated by neutral beams and the 4th harmonic 60 MHz fast wave. In this paper, we investigate how the synergy can occur using ORBIT-RF coupled with AORSA. Preliminary simulations suggest that damping of 4th harmonic FW on beam ions accelerates them above the injection energy, which may allow significant damping of 6th harmonic FW on beam ion tails to produce synergy.

  3. Pupils’ Conception of Organic Foods and Healthy Eating in School : QUALITATIVE INSIGHTS FROM FOCUS GROUP INTERVIEWS WITH 5th AND 7th GRADE PUPILS IN A COPENHAGEN ELEMENTARY SCHOOL

    DEFF Research Database (Denmark)

    Andersen, Stine; Burkal, Anna

    2010-01-01

    Adult habits, including unhealthy eating patterns, are largely established during a person´s childhood and early youth. In this connection, public schools are important health promoting platforms due to their potential for encouraging interest, knowledge and learning about health related issues. The main aim of the study was to shed light on primary and lower secondary school pupils´ everyday experience with food, nutrition, ecology and health in connection to public organic school food, using the municipality of Copenhagen as a case. We have examined how a procurement and provision strategy that primarily originates from “backstage agents” such as engaged politicians and civil servants and governed by administrative priorities, is perceived among agents at the front stage arena - the school. Furthermore we have investigated to which degree the pupils experience a connection between the “organicness” of the food program and the underlying organic supply chain principles, and to which degree the pupils experience a connection between the “organicness” of the food program and classroom initiatives in subjects related to ecology and health. In February 2008, we approached a public school which proved willing to participate in our study. Subsequently, over a period of four weeks, we designed an interview guide used to conduct focus group interviews with pupils from grades 5 and 7, which were then transcribed. In general, pupils were very interested in ecology as a subject. However it seems that they do not see a very strong connection between the healthy, organic meals offered at school and class room activities related to health and ecology. The pupils did not feel that they had been involved in the decision to establish organic and healthy food procurement. As a result they held that they did not feel very committed or engaged in the school provision initiative, and the organic and healthy food procurement was not highly sought after on the part of the pupils. This appears to justify a distinction between the perspective that front stage actors have, including pupils, and the perspective of politicians and planners that operate back stage. The distance between these two stages, which tends to increase in large scale municipal school food systems, is an important challenge to address when planning school food interventions. There seems to be a potential for linking organic school food service more closely with curricular activities, and for linking issues of healthier eating and organic food supply. There is also a need for greater involvement of the pupils and other front stage actors when the food service system and food related curricular activities are planned.

  12. Fractions in elementary education

    Quinn, Frank

    2013-01-01

    This paper is one of a series in which elementary-education practice is analyzed by comparison with the history of mathematics, mathematical structure, modern practice, and (occasionally) cognitive neuroscience. The primary concerns are: Why do so many children find elementary mathematics difficult? And, why are the ones who succeed still so poorly prepared for college material needed for technical careers? The answer provided by conventional wisdom is essentially that mathematics is difficult. Third-graders are not developmentally ready for the subtlety of fractions, for instance, and even high-performing students cannot be expected to develop the skills of experienced users. However we will see that this is far from the whole story and is probably wrong: elementary-education fractions are genuinely harder and less effective than the version employed by experienced users. Experts discard at least 90% of what is taught in schools. Our educational system is actually counterproductive for skill development, and...

    2013-09-01

    Full Text Available Elementary particles, i.e. the basic constituents of nature, are characterized by quantum recurrences in time. The flow of time of every physical system can be therefore decomposed in elementary cycles of time. This allows us to enforce the local nature of relativistic time, yielding interesting unified descriptions of fundamental aspects of modern physics, as shown in recent publications. Every particle can be regarded as a reference clock with time resolution of the order of the Compton time particle, many orders of magnitude more accurate than the atomic clocks. Here we report basic implications about the resulting notion of time.

    The progress of science and technology emphasizes the connection between different domains and disciplines. The technology development and changing demands of the labour market require upgrading and renewing of learning outcomes in higher education, especially in engineering fields. The Life Long Learning (LLL) procedure must be the platform offering the required qualifications for the demands of companies and engineering professionals all over the world in order to support their competitiveness. In this paper we describe an improved proposal for accreditation of one important subject in engineering, namely Control Systems. The described procedure could be applied in the frame of LLL and also in classical engineering education systems, such as university and college education, in order to harmonize the recognition of engineering degrees in Europe and outside the Europe. Furthermore we state the necessary learning outcomes in the subject of Control Systems in engineering at Bachelor level (6th level of European Qualification Framework (EQF) and propose a process to test the qualifications. © 2013 IEEE.

    Lake Ohrid shared by the Republics of Albania and Macedonia is formed by a tectonically active graben within the South Balkan and suggested to be the oldest lake in Europe. Several studies have shown that the lake provides a valuable record of climatic and environmental changes and a distal tephrostratigraphic record of volcanic eruptions from Italy. Fault structures identified in seismic data demonstrate that sediments have also the potential to record tectonic activity in the region. Here, we provide an example of linking tephrostratigraphic information and environmental changes with tectonic activity and anthropogenic impact. Historical documents indicate that a major earthquake destroyed the city of Ohrid in the early 6th century AD. This earthquake is documented in multichannel seismic profiles, in parametric sediment echosounder profiles, and in a ca. 10 m long sediment record from the western part of the lake. The sediment record exhibits a ca. 2 m thick mass wasting deposit, which is chronologically well constrained by the underlying 472 AD/512 AD tephra and cross correlation with other sediment sequences with similar geochemical characteristics of the Holocene.

    Full Text Available Objectives: The study aims to identify the impact of minimal support on medical students' mobile learning activities. Methods: The study was performed at the Sultan Qaboos University, Oman, on 129 medical students in their 7th year. The study consisted of a quantitative survey of the students, focussing on their mobile learning activities during their 6th year, while using their own mobile devices (such as smart phones for mobile learning activities. In addition, their perceptions of barriers to, and advantages of, using mobile devices were investigated. Data were analysed using Microsoft Excel and EpiInfo. Results: All students used their mobile device as telephones and used most of the sophisticated applications. There was significantly less usage made of medical applications, such as clinical guidelines and medical reference tools. Barriers were screen size, cost, limited memory and battery. Advantages were time-saving, ease of access and use. Few students (14 highlighted lack of institutional support as a problem. Conclusions: Lack of support does not mean lack of usage. It does, however, mean predominantly simple usage. Given the importance of mobile devices in modern medical practice, this has strong negative implications for the professional preparedness of students studying in such environments.

    2012-03-01

    Full Text Available Abstract The 6th Benelux Bioinformatics Conference (BBC11 held in Luxembourg on 12 and 13 December 2011 attracted around 200 participants, including internationally-renowned guest speakers and more than 100 peer-reviewed submissions from 3 continents. Researchers from the public and private sectors convened at BBC11 to discuss advances and challenges in a wide spectrum of application areas. A key theme of the conference was the contribution of bioinformatics to enable and accelerate translational and clinical research. The BBC11 stressed the need for stronger collaborating efforts across disciplines and institutions. The demonstration of the clinical relevance of systems approaches and of next-generation sequencing-based measurement technologies are among the existing opportunities for increasing impact in translational research. Translational bioinformatics will benefit from research models that strike a balance between the importance of protecting intellectual property and the need to openly access scientific and technological advances.

  5. Reconstructing the diets of Greek Byzantine populations (6th-15th centuries AD) using carbon and nitrogen stable isotope ratios.

    2011-12-01

    Documentary evidence and artistic representations have traditionally served as the primary sources of information about Byzantine diet. According to these sources, Byzantine diet was based on grain (primarily wheat and barley), oil, and wine, supplemented with legumes, dairy products, meat, and marine resources. Here, we synthesize and compare the results of stable isotope ratio analyses of eight Greek Byzantine populations (6th-15th centuries AD) from throughout Greece. The ?(13) C and ?(15) N values are tightly clustered, suggesting that all of these populations likely consumed a broadly similar diet. Both inland and coastal Byzantine populations consumed an essentially land-based C(3) diet, significant amounts of animal protein, and possibly some C(4) plants, while no evidence of a general dependence on low-?(15) N legumes was observed. One interesting result observed in the isotopic data is the evidence for the consumption of marine protein at both coastal sites (a reasonable expectation given their location) and for some individuals from inland sites. This pattern contrasts with previous isotopic studies mainly on prehistoric Greek populations, which have suggested that marine species contributed little, or not at all, to the diet. The possibility that fasting practices contributed to marine protein consumption in the period is discussed, as are possible parallels with published isotope data from western European medieval sites.

    Full Text Available Abstract While malaria research has traditionally been strong in Europe, targeted and sustained support for cooperative malaria research at EU level, namely through the EU's 6th and 7th Framework Programmes for research and technological development, FP6 (2002-2006 and FP7 (2007-2013, has boosted both impact and visibility of European malaria research. Most of the European malaria research community is now organized under a number of comprehensive and complementary research networks and projects, assembled around four key areas: (1 fundamental research on the malaria parasite and the disease, (2 development of new malaria drugs, (3 research and development of a malaria vaccine, and (4 research to control the malaria-transmitting mosquito vector. Considerable efforts were undertaken to ensure adequate participation of research groups from disease-endemic countries, in particular from Africa, with the long-term aim to strengthen cooperative links and research capacities in these countries. The concept of organizing European research through major strategic projects to form a "European Research Area" (ERA was originally developed in the preparation of FP6, and ERA formation has now turned into a major EU policy objective explicitly inscribed into the Lisbon Treaty. EU-funded malaria research may serve as a showcase to demonstrate how ERA formation can successfully be implemented in a given area of science when several surrounding parameters converge to support implementation of this strategic concept: timely coincidence of political stimuli, responsive programming, a clearly defined - and well confined - area of research, and the readiness of the targeted research community who is well familiar with transnational cooperation at EU level. Major EU-funded malaria projects have evolved into thematic and organizational platforms that can collaborate with other global players. Europe may thus contribute more, and better, to addressing the global research agenda for malaria.

    2010-12-01

    Through involvement in authentic research experiences teachers improve their content knowledge, deepen their understanding of the research process, and rejuvenate their interest in science. These positive results of fieldwork transfer into the classroom, directly benefiting students. The ARMADA project provided me with a three week research experience aboard the Amundsen (Canadian Coast Guard science vessel) which enriched and strengthened me professionally. Guided by master and early career scientists, I took part in specific research techniques and deep scientific discourse. My immersion in ocean science was so stimulating that I was inspired to share that excitement with my students. The fascination my students showed for basic experiments and ocean related activities fueled my interest further and I began to research more deeply which led to Climate Literacy and Polar Studies as essentials in my science curriculum. Over the following years I continued to expand and refine the workshops and activities students take part in. Three years after the research experience students still love the science explorations we embark upon together. This past year a group of students became so excited about Polar Science and Climate that they authored a 36 page non fiction book for upper elementary and middle school students entitled, "Changing Poles, Changing Planet: Climate Change vs. The Earth". Seven of the authors decided to continue their science outreach work by creating an educational video focusing on the basics of climate science and what children can do to lower carbon emissions. The book and video were distributed to educators as well as scientists at the International Polar Year Science Conference in June, 2010. In August some of these students presented their work at a Sustainability festival that was organized by M-CAN a local climate action group. Two of these students (who have left my class and started 6th grade at the middle school)recently decided to form a Climate Club and their goal is to continue to research and teach others about climate science. Their enthusiasm and desire to teach others is a result of exposure to authentic science issues in school and my research experience is what changed the way I teach science which made this possible.

  9. New Simple Torque-Sensorless Torque Control for Quasi-Perfect Compensation of 6th Harmonic Torque Ripple Due to Nonsinusoidal Distribution of Back EMF of PMSM

    Science.gov (United States)

    Shinnaka, Shinji; Kishida, Hideo

    This paper proposes a new torque-sensorless torque control method for permanent-magnet synchronous motors (PMSMs). The proposed method can almost perfectly compensate the 6th harmonic torque ripple that is caused by the nonsinusoidal distributions of the back EMF and rotor magnetic flux of PMSMs. The torque control system is, in principle, constructed on the basis of the vector control, but has two new dedicated speed-varying devices—a harmonic torque observer and current controller. The speed-varying harmonic torque observer can estimate the harmonic component over a wide speed range, even in the case where the produced torque is constant, and generate a suitable compensating signal. The speed-varying current controller shows stable control performance over a wide speed range, it can fully track the compensated current command containing the dc and 6th harmonic components. The effectiveness of the proposed method is examined and verified through extensive numerical experiments.

    2014-01-01

    The Codex Rossanensis is a 6th century Bizantine illuminated manuscript written on purple parchment and conserved at the Museo Diocesano in Rossano Calabro, Italy. It is one of the oldest surviving illuminated manuscripts of the New Testament. The challenge of the analysis of the Codex Rossanensis lies in the lack of analytical information on the pictorial media used in the Early Middle Ages. Even though old-medieval illuminated manuscripts have been deeply studied from the historical standpoint, they have been rarely described in their material composition. This paper presents the results obtained during the measurements campaign (June 2012 - November 2013). The spectroscopic analyses performed by Raman, micro-FTIR and XRF allowed for the complete characterization of the pictorial palette, the inks, the support and the material used in a previous restoration treatment. To the author knowledge the article shows the first experimental evidence of the usage of the elderberry lake in a 6th century illuminated ma...

    This study examined the impact of an inquiry-based instructional intervention on (a) children's ability to conduct science inquiry overall and to use specific skills in inquiry, and (b) narrowing the gaps in children's ability among demographic subgroups of students. The intervention consisted of instructional units, teacher workshops, and classroom practices. The study involved 25 third- and fourth-grade students from six elementary schools representing diverse linguistic and cultural groups. Quantitative results demonstrated that the intervention enhanced the inquiry ability of all students regardless of grade, achievement, gender, ethnicity, socioeconomic status (SES), home language, and English proficiency. Particularly, low-achieving, low-SES, and English for Speakers of Other Languages (ESOL) exited students made impressive gains. The study adds to the existing literature on designing learning environments that foster science inquiry of all elementary students.

    When grades lose their informative value because the percentage of students receiving the best grade rises without any corresponding increase in ability, this is called grade inflation. Conventional wisdom says that such grade inflation is unavoidable since it is essentially costless to award good grades. In this paper, we point out an effect driving into the opposite direction: Grade inflation is not actually costless, since it has an impact on future cohorts of graduates, or, put differentl...

  15. Medical students’ skills in image interpretation before and after training: A comparison between 3rd-year and 6th-year students from two different medical curricula

    International Nuclear Information System (INIS)

    The purpose of this study was to assess student's performance in the interpretation of images before and after training in radiology, by comparing two groups, 6th-year and 3rd-year students, from two different medical curricula. Students participated in an anonymous evaluation consisting of the interpretation of 12 radiological images accompanied with the salient history and clinical data by answering 60 open-ended questions about technique, anatomy, semiology, and clinics. The number of correct, incorrect and blank responses of each group was used to compare pre- and post-training results. Unpaired two-sample t-test was used to evaluate differences between groups. A significant increase in correct responses was found in both groups after training. The comparison between both groups did not show differences for incorrect answers of the whole test and correct answers about anatomy in the pre-training evaluation. The percentage of correct answers to the median question improved from 15.5% to 53.3% for 6th-year students and from 8.3% to 41.1% for 3rd-year students. The post-training evaluation showed a significant increase of correct answers of 6th-year students with respect to 3rd-year students (mean ± standard deviation 53.6 ± 31.3% and 38.7 ± 29.9% respectively), mainly due to differences in technical and clinical questions. This study provides objective and quantitative evidence of pre- and post-training student skills in image interpretation. The similarities found in the previous level of knowledge and skills of both groups emphasizes the suitable change of the first-time training in radiology, from the 6th to the 3rd year course in medical curricula.

    Science.gov (United States)

    Page, Purlie M.

    At the local level, G Middle School has the highest district-wide percentage of 6th grade science students who are not meeting standards. It is imperative that G middle school take corrective action to reduce the number of students failing to meet state science standards. Dewey's theory of conceptual framework, which involves knowledge constructed on a person's personal experience and mind activity through active forms of learning, guided this study. The goal of the study was to determine whether inquiry-based science modules produce greater 6th grade science achievement, as measured by an equivalent instrument of the science section of the Georgia Criterion-Referenced Competency Test, when compared to traditional instruction among eastern Georgia 6th graders. The sample consisted of 230 students in the nonintervention group and 119 students in the intervention group. All students were from intact classes. At the end of the intervention, an independent t test was conducted to analyze the scores. According to the study t test, (t = 12.33, df = 304.56, p increasing student motivation towards, comprehension of, and interest in science concepts. At the local level, these inquiry lessons can be shared with science teachers across grade levels and within the district to improve county-wide science scores. An increase in student interest and comprehension of science concepts could ultimately lead to the United States producing more students in the fields of science, technology, engineering, and mathematics (STEM) education.

Organized by the BioBricks Foundation, the SBx.0 conference series brings together leading researchers, students, industry executives, and policy makers from around the world to share, consider, debate, and plan efforts to make biology easier to engineer. Historically held every two years, the SBx.0 conferences are held in alternating locations in the United States, Europe, and Asia to encourage global participation and collaboration so that the ramifications of synthetic biology research and development are most likely to be safe ethical, and beneficial. On 9-11 July 2013, the 6th installment of the synthetic biology conference series (SB6.0) was held on the campus of Imperial College London (http://sb6.biobricks.org). The SB6.0 conference was attended by over 700 people, and many more were able to participate via video digital conference (http://sb6.biobricks.org/digital-conference/). Over the course of three days, the SB6.0 conference agenda included plenary sessions, workshops, and poster presentations covering topics ranging from the infrastructure needs arising when “Systematic Engineering Meets Biological Complexity” and design-led considerations for “Connecting People and Technologies” to discussions on “Engineering Biology for New Materials,” “Assessing Risk and Managing Biocontainment,” and “New Directions for Energy and Sustainability.” The $10,150 grant awarded by the U.S. Department of Energy (DE-SC0010233) to the BioBricks Foundation was used to provide partial reimbursement for the travel expenses of leading researchers from the United States to speak at the SB6.0 conference. A total of $9,450 was used to reimburse U.S. speakers for actual expenses related to the SB6.0 conference, including airfare (economy or coach only), ground transportation, hotel, and registration fees. In addition, $700 of the grant was used to offset direct administrative costs associated with selecting speakers (preparing announcements, evaluating abstract submissions) and handling travel arrangements. Leading U.S. researchers selected to speak at the SB6.0 conference included: Adam Arkin, Ph.D. Division Director of the Physical Biosciences Division at the Lawrence Berkeley National Laboratory and Professor in the Department of Bioengineering at UC Berkeley Jay Keasling, Ph.D. Professor in the Department of Bioengineering at Berkeley, Senior Faculty Scientist and Associate Laboratory Director of the Lawrence Berkeley National Laboratory, and Chief Executive Officer of the Joint BioEnergy Institute. Debra Mathews, Ph.D. Assistant Director for Science Programs for the Johns Hopkins Berman Institute of Bioethics, Assistant Professor in the Department of Pediatrics, and Affiliate Faculty in the McKusick-Nathans Institute of Genetic Medicine, Johns Hopkins School of Medicine. Richard Murray, Ph.D. Thomas E. and Doris Everhart Professor of Control & Dynamical Systems and Bioengineering at Caltech. Sarah Richardson, Ph.D. Distinguished Postdoctoral Fellow in Genomics at the Lawrence Berkeley National Laboratory and the Department of Energy Joint Genome Institute. and others (for a complete listing of speakers presenting at the SB6.0 conference see http://sb6.biobricks.org/speakers/) The SB6.0 conference was the largest synthetic biology conference to date, and highlights of the SB6.0 conference have been published in a special issue of ACS Synthetic Biology (http://pubs.acs.org/toc/asbcd6/3/3). The BioBricks Foundation appreciates the support of the U.S. Department of Energy in helping to make this most influential and important conference in the field of synthetic biology a success.

    Nehir SERT

    2008-01-01

    Full Text Available The aim of this study was to examine whether the 5th grade elementary school curricula of Turkish, English, Mathematics, and Science and Technology courses were congruent with the principles and standards of the constructivist education. Qualitative research methods were used in this small-scale case study which was conducted in a private elementary school in Ankara. The data were gathered through semi-structured interviews and document analyses in the academic year of 2007-2008. The population of interest consisted of 2 school directors, 1 Turkish teacher, 3 English teachers, 4 Mathematics teachers, and 3 Science and Technology teachers. Descriptive analytical framework was employed for the analysis of the interviews. A rubric and a list of standards were used so as to provide a set of criteria for the analyses of the data. The findings indicate that the performances of the curricula under investigation are congruent with the principles of the constructivist education. Similarly, the stated and unstated intents of the curricula are congruent with their performances and the standards of the constructivist education. However, in-depth analyses of the findings signify that in certain areas of the curricula such as the contents, learning processes, evaluation processes, the use of the information technology, and the other resources are marked by some difficulties and ambiguity.

  20. Elementary GLOBE: Cloudscape

    Science.gov (United States)

    2008-12-01

    A learning activity for the "Do You Know That Clouds Have Names?" book in the Elementary GLOBE series. Using information from the book and their observations, students construct a sky scene with trees and buildings as reference points on the ground and cloud types ordered by altitude in the sky. Students will describe clouds using their own vocabulary and will then correlate their descriptions with the standard classifications of cloud types used by the GLOBE Program. The purpose of the activity is to help students identify some of the characteristics of clouds and to enable students to observe clouds, describe them in a common vocabulary, and compare their descriptions with the official cloud names. Students will be able to identify cloud types using standard cloud classification names. They will know that the names used for the clouds are based on three factors: their shapes, the altitude at which they occur, and whether they are producing precipitation.

  1. Discerning Elementary Particles

    CERN Document Server

    Muller, F A

    2009-01-01

    We extend the quantum-mechanical results of Muller & Saunders (2008) establishing the weak discernibility of an arbitrary number of similar fermions in finite-dimensional Hilbert-spaces in two ways: (a) from fermions to bosons for all finite-dimensional Hilbert-spaces; and (b) from finite-dimensional to infinite-dimensional Hilbert-spaces for all elementary particles. In both cases this is performed using operators whose physical significance is beyond doubt.This confutes the currently dominant view that (A) the quantum-mechanical description of similar particles conflicts with Leibniz's Principle of the Identity of Indiscernibles (PII); and that (B) the only way to save PII is by adopting some pre-Kantian metaphysical notion such as Scotusian haecceittas or Adamsian primitive thisness. We take sides with Muller & Saunders (2008) against this currently dominant view, which has been expounded and defended by, among others, Schr\\"odinger, Margenau, Cortes, Dalla Chiara, Di Francia, Redhead, French, Tell...

    2008-12-01

    A learning activity for the "Do You Know That Clouds Have Names?" book in the Elementary GLOBE series. Each student will be given the opportunity to create their own cumulus cloud out of white paper and mount it on blue paper. Students will also complete the Cloud Fun Student Activity Sheet that includes a description of the cloud and what the weather was like on the day the cloud was observed. The purpose of the activity is to help students identify cumulus clouds and observe the weather conditions on days that they see cumulus clouds. Students will learn about a cumulus cloud's shape and appearance, how to verbally describe cumulus clouds, and what the weather is generally like when these clouds appear in the sky.

  4. Elementary Preservice Teachers’ Change

    Alenka Lipovec

    2008-12-01

    Full Text Available In the last two decades investigation of teachers’ beliefs and conceptions and teachers‘possibilities for change has been one of the points of emphasis in mathematics education. We propose the concept and design of an intervention program including five stakeholders on the basis of a teacher–student–parent–preservice teacher–teacher educator relation. The main idea is comprised of reversed roles in teaching and learning process i.e. elementary school preservice teachers should adopt beliefs and conceptions from the mathematically promising students (age 6-12. The program is defined by 10 relationships among stakeholders and was evaluated from various viewpoints. In this paper, we highlight the effect on the preservice teachers’ competencies during the longitudinal study. We have focused on the gap between desired and achieved competences as viewed by the preservice teachers. Overall results speak in favour of presented approach.

    The European Union launched the 6th Framework Programme for Research, Technological Development and Demonstration in 2002. Initially, Hungary participated in the 6th Framework Programme as an associate member, but since 2004 it has taken part as a Member State. Besides mobilizing their own resources, research organizations entering winning bids to framework programme tenders enjoy considerable financial support from the European Union, while participating states also contribute to the costs of the cooperation from their national budgets. Therefore, it is very important to recognize and evaluate the achievements of domestic participation. By collecting, processing and analyzing available data, the authors evaluate the bid activity and the successfulness of Hungarian research organizations in the thematic priority area covering life sciences of the 6th Framework Programme. When judging success, the authors not only consider the level of Community financial contribution, but also the participation of Hungarian researchers in international research networks. The article contains an analysis of the submitted and supported works from various aspects such as by year, calls for bids, research fields etc. for projects in the implementation of which Hungarian partners were also involved. The authors present the cost settlement methodologies applied, and traditional and new project types. They analyse the activity of coordinators and outline European expectations with regard to the participation of small and medium-sized enterprises and women. One of the important objectives of the analysis is to draw conclusions so that participants will be able to adapt them during the 7th Framework Programme, 2007-2013. PMID:17631471

  6. Prognostic factors and significance of the revised 6th edition of the AJCC classification in patients with locally advanced nasopharyngeal carcinoma

    International Nuclear Information System (INIS)

    Purpose: To compare the 4th edition 1992 and 6th edition 2002 of the American Joint Committee on Cancer (AJCC) staging systems, to evaluate the paranasopharyngeal structures and lymph node involvement, and to define the prognostic significance of the above factors to overall survival (OS) in patients with locally advanced nasopharyngeal carcinoma (NPC). Patients and Methods: CT images of 162 patients, who were diagnosed with NPC and received irradiation alone or chemotherapy and irradiation, were retrospectively reviewed. CT scans, performed prior to and after the completion of treatment, were reviewed. Results: The parapharyngeal space was found to be involved very commonly (98%). 50 of 162 patients (31%) displayed parapharyngeal extension of the tumor to degree A, 59 patients (36%) showed degree B, and 50 patients (31%) degree C nasopharyngeal extension. According to the AJCC 6th edition 2002, patients were distributed into stages IIA, IIB, III, IVA, and IVB. By contrast, using the AJCC 4th edition 1992, patients were distributed into stages III and IV only. After a median follow up of 71.1 months, median survival was 60.7 months, with a 2-year survival rate of 71.3% and a 3-year survival rate of 62.2%. Multivariate analysis identified age, degree of parapharyngeal lateral extension, cavernous-sinus-infiltration, and size of infiltrated lymph nodes as independent prognostic factors for OS. Conclusion: The 6th revision of TNM staging reported herein, provides a more staging reported herein, provides a more uniform distribution of patients between stages. The degree of tumor extension into the parapharyngeal space should be considered in future TNM staging revisions. (orig.)

  8. Replacement of the 5th and 6th level vanes of the low pressure part of the turbine 13K 125 in the TPP 'Oslomej' - Kichevo (Macedonia)

    International Nuclear Information System (INIS)

    The condensation turbine 13K with nominal power of 125 MW is an axial three-cylindrical machine with inter-level steam heating and a 5-level heating system. The turbine consists: high-pressure cylinder FT; medium-pressure cylinder MP and low-pressure cylinder LP. The 5th level vanes of the LP cylinder have Baumann reinforcement and they are bound in packages of ten vanes each. During the 1994 overhaul, the following examinations were carried out: examination without destruction with penetrant and magnetic flux. It was found out that there were some defects and cracks on the 5th and 6th level vanes of the LP-rotor and some of the stellite plates had come off completely or some smaller parts were missing. At the places where stellite parts were missing the basic material was eroded to a large extent. On the basis of the report all damaged and loose stellite plates were removed, i.e. 50% of the 6th level and 87% of the 5th level. The turbine has since operated in such a condition and it has worked for additional 15000 working hours. During this period the condition of the vanes has been monitored and some examinations and measurements have been undertaken. It has been established that the current technical condition of the rotating 5th and 6th level vanes of the LP-turbine, where the stellite plates had been removed, indicates that they are seriously damaged and an urgent replacement of the vanes is absolutely necessary.

Evaluation of Developmental Delay in Infants Who Came in for 6th Month Vaccination in Isfahan City Health Centers. Iran J Child Neurol 2012;6(2: 29-32. Objective Developmental delay is one of the most common causes of conferring the pediatric neurologist. The main part of neurological growth and development occur in the first two years especially in the first 6 months of life. Metabolic or skeletal diseases are important causes of developmental delay. Early diagnosis of deviance from the normal diagram of development in lower ages is important. Materials & Methods Specific ages and stages questionnaires (ASQ for 6 months was completed in the health centers for 800 infants conferring for their vaccination in Isfahan and the retest was performed at 24 months of age by ASQ and then these two questionnaires were compared. Results 10.5% of the infants were delayed in at least one domain. At 24 months, 38.4% of them remained delayed; 21.1% in one domain, 9.6% in two domains, 3.8% in four domains and 3.8% in five domains. Of the children who had problem in communication, 20%; in gross motor, 25%; in fine motor, 20%; and in problem solving, 30% remained delayed. In the personal social domain, none of the delayed children at 6 months remained delayed at 24 months. Conclusion ASQ is feasible, inexpensive, easy to use and was appreciated by the parents. It can be used as a screening test for detection of developmental delay in lower ages, but its results must be followed by other standard tests or diagnostic tools.References Lewis R, Palfreg GS.

    Efford, Jackson T.; Bylsma, Rebecca J.; Clarkson, Bruce D.; Pittari, Adrian; Mauriohooho, Kate; Moon, Vicki G.

    2014-10-01

    The 6th of August 2012 eruption of Te Maari (Mt Tongariro, New Zealand) generated wet pyroclastic density currents (PDCs) which caused widespread dieback of vegetation (singed, brown foliage) in their path. An absence of significant charcoal formation suggests that PDC temperatures were mostly below 250 °C. Textural evidence for liquid water being present in the matrices during emplacement (vesicles) suggests that temperatures were areas, where only the most susceptible species were browned while others remained healthy and unaffected, temperatures were probably around 51-58 °C. These results have relevance to volcanic hazard mitigation and risk assessment, especially on the popular Tongariro Alpine Crossing.

  14. Validation of RELAP5-3D computer code on the MSLB problem within the 6th dynamic AER benchmark. Rev. 0

    International Nuclear Information System (INIS)

    The benchmark was concerned with a two-side break of a main steam line at a NPP with VVER 440/213 reactor units. RELAP5-3D was tested on an input deck for the Dukovany NPP. The input model is a detailed 6-loop model, modified based on specifications of the 6th dynamic AER benchmark. The input deck stems from the 'international' three-loop input deck for the Jaslovske Bohunice NPP, prepared within the IAEA regional programme 'Safety Assessment of VVER-440/213'. Furthermore the model was extended and modified with respect to Dukovany specifications and needs for more detailed analyses. (P.A.)

Universities choose grading standards to maximize total wages of graduates. Job placement and wages hinge on a ?rm’s productivity assessment given a student’s university, grade and productivity signal. We identify conditions under which better universities set lower grading standards, exploiting the fact that ?rms cannot distinguish between “good”...

  8. Slope modification of open pit wall using a genetic algorithm - case study: southern wall of the 6th Golbini Jajarm bauxite mine

    Scientific Electronic Library Online (English)

    K., Goshtasbi; M., Ataei; R., Kalatehjary.

    2008-10-01

    Full Text Available In this paper a genetic algorithm is used in a heavily jointed rock mass in order to investigate the critical circular slip surface and modification of slope surface. This method was applied to the southern wall of the 6th Golbini Jajarm bauxite mine. The mine is the largest bauxite deposit in Iran, [...] located to the northeast of the town of Jajarm in the Khorasan province. Estimated reserve of bauxite in this deposit is about 160 million tonnes. Field and laboratory investigations were conducted in order to determine rock mass behaviour. A genetic algorithm code that uses the Simplified Bishop method as an objective function was developed for finding the safety factor of circular slip surfaces. Sensitivity analysis was applied to determine the optimum values of the genetic algorithm variables, such as population size, selection method, crossover and mutation rates. After finding the critical circular slip surface, slope modification is carried out by removing unstable sections from marked critical slip surfaces, and this process is repeated until the last unsafe section is removed. Based on this code, modification occurred during 7 steps, by reaching a safety factor of 1.3 in the last step. Finally, the modified slope angle of the southern wall of the 6th Golbini Jajarm bauxite mine was determined to be 48.44 degrees.

    2007-01-01

    We prove that the obstruction bundle used to define the cup-product in Chen-Ruan cohomology is determined by the so-called `age grading' or `degree-shifting numbers'. Indeed, the obstruction bundle can be directly computed using the age grading. We obtain a Kunneth Theorem for Chen-Ruan cohomology as a direct consequence of an elementary property of the age grading, and explain how several other results - including associativity of the cup-product - can be proved in a similar way.

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

    Science.gov (United States)

    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.

  20. Irradiation of fuels and materials in the Jules Horowitz reactor: The 6th European Union JHR co-ordination action (JHR-CA)

    International Nuclear Information System (INIS)

    The Fermine thematic network in the 5th FP pointed out the need for a new MTR facility in Europe to answer the continuous need of irradiation capabilities for fission power reactors and fusion facilities and to face the ageing of present MTRs. The Jules Horowitz Reactor (JHR) Project in Cadarache copes with this context, as an international service-oriented user-facility. In the field of nuclear fuels and materials irradiation experiments, a 6th FP co-ordination action, called JHR-CA, has started at the beginning of 2004 for 2 years. The main objective is to network existing expertise on development of a new generation of experimental devices, through definition of conceptual designs, instrumentation and related in-reactor services. This paper presents the outline of the JHR project, the organization of the JHR-CA programme, and a choice of irradiation device conceptual design results. (author)

The objective of this study was to evaluate the prognostic impact of the new staging system on esophageal cancer patients treated with CRT. Methods and Materials: A retrospective review was performed on 301 consecutive esophageal squamous cell carcinoma patients treated with CRT. Comparisons were made of the prognostic impacts of the 6th and 7th staging systems and the prognostic impacts of stage and prognostic groups, which were newly defined in the 7th edition. Results: There were significant differences between Stages I and III (p < 0.01) according to both editions. However, the 7th edition poorly distinguishes the prognoses of Stages III and IV (p = 0.36 by multivariate analysis) in comparison to the 6th edition (p = 0.08 by multivariate analysis), although these differences were not significant. For all patients, T, M, and gender were independent prognostic factors by multivariate analysis (p < 0.05). For the Stage I and II prognostic groups, survival curves showed a stepwise decrease with increase in stage, except for Stage IIA. However, there were no significant differences seen between each prognostic stage. Conclusions: Our study indicates there ar Conclusions: Our study indicates there are several problems with the 7th TNM staging system regarding prognostic factors in patients undergoing CRT.

    Trisha Kagey Boswell is a third-grade teacher at an elementary school in Montgomery County, Maryland, where she has taught for eight years. Her school is an art-integrated magnet school. When she wrote this chapter, she was a first-year teacher, teaching fourth grade. She reflects on trying to create in her own classroom the inquiry experiences she enjoyed in a physics course as part of her preservice program. She also describes her efforts at tracking the influence of such inquiry-based instruction by documenting changes in her students' understandings of what scientists do. Writing in the middle of a unit on electric circuits, she comments upon what they had done so far, describes what they were in the process of doing, and anticipates an event in which the students would be communicating their findings.

    Purpose Low socioeconomic status is an important risk factor for child psychiatric problems. Low socioeconomic status is also associated with psychiatric problems later in life. We investigated the effects of group bullying on clinical characteristics and psychopathology in elementary school students using child-welfare facilities. Methods Three hundred and fifty-eight elementary school students using child-welfare facilities were recruited. The School Bullying Self Rating Questionnaire was used to assess group bullying. To evaluate related psychopathology, the Children’s Problem-Behavior Screening Questionnaire, the Children’s Depression Inventory, the Beck Anxiety Inventory, the Suicidal Ideation Questionnaire, Young’s Internet Addiction Scale, and Conners–Wells’ Adolescent Self-Report Scale were applied. Samples were classified according to school grade (lower or upper), and each group’s characteristics were compared as they related to bullying victims versus non-victims. Results The prevalence rate of group bullying was 22% in the lower-grade group and 12% in the higher-grade group. Bullying victims in lower grades reported high somatization, depressive symptoms, Internet addiction, and attention deficit hyperactivity disorder tendencies, whereas those in upper grades reported cognitive problems, symptoms of depression and anxiety, suicidal ideation, Internet addiction, and attention deficit hyperactivity disorder tendencies. Somatization and depressive symptoms were significant predictors of bullying in the lower-grade group, and anxiety was a significant predictor of bullying in the upper-grade group. Conclusion This study demonstrated that elementary school students using child-welfare facilities might have an increased risk of being bullied and that bullying victims may have different psychopathologies depending on their ages.

    Chronic kidney disease (CKD) is a global problem. Slowing CKD progression is a major health priority. Since CKD is characterized by complex derangements of homeostasis, integrative animal models are necessary to study development and progression of CKD. To study development of CKD and novel therapeutic interventions in CKD, we use the 5/6th nephrectomy ablation model, a well known experimental model of progressive renal disease, resembling several aspects of human CKD. The gross reduction in renal mass causes progressive glomerular and tubulo-interstitial injury, loss of remnant nephrons and development of systemic and glomerular hypertension. It is also associated with progressive intrarenal capillary loss, inflammation and glomerulosclerosis. Risk factors for CKD invariably impact on endothelial function. To mimic this, we combine removal of 5/6th of renal mass with nitric oxide (NO) depletion and a high salt diet. After arrival and acclimatization, animals receive a NO synthase inhibitor (NG-nitro-L-Arginine) (L-NNA) supplemented to drinking water (20 mg/L) for a period of 4 weeks, followed by right sided uninephrectomy. One week later, a subtotal nephrectomy (SNX) is performed on the left side. After SNX, animals are allowed to recover for two days followed by LNNA in drinking water (20 mg/L) for a further period of 4 weeks. A high salt diet (6%), supplemented in ground chow (see time line Figure 1), is continued throughout the experiment. Progression of renal failure is followed over time by measuring plasma urea, systolic blood pressure and proteinuria. By six weeks after SNX, renal failure has developed. Renal function is measured using 'gold standard' inulin and para-amino hippuric acid (PAH) clearance technology. This model of CKD is characterized by a reduction in glomerular filtration rate (GFR) and effective renal plasma flow (ERPF), hypertension (systolic blood pressure>150 mmHg), proteinuria (> 50 mg/24 hr) and mild uremia (>10 mM). Histological features include tubulo-interstitial damage reflected by inflammation, tubular atrophy and fibrosis and focal glomerulosclerosis leading to massive reduction of healthy glomeruli within the remnant population (<10%). Follow-up until 12 weeks after SNX shows further progression of CKD. PMID:23851420

  18. Assessing Numeracy in the Upper Elementary and Middle School Years

    Full Text Available Numeracy is the ability or tendency to reason critically about quantitative information. The preponderance of published research on numeracy examines this construct among either pre-K or early elementary samples, students with developmental challenges, or is focused on post-secondary and adult cohorts. The numeracy skills of upper-elementary and middle school students is less documented and understood, most notably because of the lack of valid instruments that are developmentally appropriate for the age range. A numeracy scale for use among upper-elementary and middle school students is introduced in this paper. Scale validation was performed using a gender-balanced, racially / ethnically diverse sample of 3rd through 8th grade students (N=197 from a private, Catholic K-8 school in Santa Clara County, California. Construct validity is supported by strong, positive correlations with the three subscales of the Cognitive Abilities Test (CogAT as well as the Iowa Test of Basic Skills Mathematics test, a standardized academic achievement domain assessment. A preliminary exploration of the critical-thinking dispositional correlates of numeracy suggests a positive relationship with students’ self-reported creative problem solving, diligence, systematicity, and fair-mindedness.

    Full Text Available The role of deliberate practice in the development of performance has been studied extensively in many contexts, such as in athletics. The construct of deliberate practice in the development of teacher performance has been receiving heightened examination lately, though the role of practice in the development of elementary social studies teachers remains essentially unexplored. The purpose of this study was to investigate the impact of a repeated practice microteaching model on the teaching behaviors of 64 elementary preservice teachers (PSTs who taught the same social studies lessons to small groups of 4th-grade students four times in succession. PST reflection journals from all PSTs, observational transcripts of 14 teaching pairs, focus group interviews with the PSTs, and informal cooperating teacher interviews revealed that the PSTs’ lessons changed over the four successive teaching episodes. The PSTs became more comfortable and confident after teaching the same social studies lesson multiple times. PSTs also reported that their lessons became better, yet the qualitative data revealed that even though their teaching became more efficient and student work correctness improved, only a few PSTs increased the cognitive demand of their questions and activities. Nonetheless, most PSTs demonstrated increased use of social studies pedagogical content knowledge through their examples and discussions, as well as increased attention to student thinking. Repeated practice field experiences seem to hold potential for elementary PSTs to develop their use ofsocial studies pedagogical content knowledge

    Full Text Available The current study aimed to reveal elementary school students’ perceptions of technology through their pictorial representations and their written expressions based on their pictorial representations. Content analysis based on the qualitative research method along with art-based inquiry was applied. The “coding system for the concepts revealed from the research data” was implemented. Visual language used in pictorial representations produce messages, with its specialized codes. The degree of students to understand and explain their perception on technology composes the visual codes in this research. The study carried out with fifth-grade elementary school students was applied to a class of 28 students. The elementary school students participating in the present study had diverse perceptions of today’s technology, and most of their perceptions of technology were based on computer and electronic household appliances. Some students’ perceptions of technology were based on the Internet and mobile device technologies. Their perceived future technology was observed as human-computer interaction in the area of computer technology. Findings were discussed followed by relevant implications.

    From the 58 papers published in 2012 in Fluid Dynamics Research, the following paper has been selected for the sixth FDR prize: The finite-difference lattice Boltzmann method and its application in computational aero-acoustics by Michihisa Tsutahara (Professor Emeritus, Kobe University, Japan), published in volume 44 (August 2012) 045507. This is a review paper of the author's recent work on the finite-difference lattice Boltzmann method (FDLBM). In this paper, the author introduces a modified FDLBM and its application to aero-acoustics. To solve the discrete Bhatnager, Gross and Krook equation for simulating fluid flow, the FDLBM applies a stable finite-difference scheme on a curvilinear coordinate system, whereas the ordinary lattice Boltzmann method uses regular lattices. It is known that for the lattice Boltzmann methods, there is difficulty in simulating high Mach number compressible flows in principle. To alleviate this, the author proposed the modified FDLBM, expanding the flexibility of setting time increments. With this FDLBM, the author has shown that it is possible to simulate compressible flows efficiently around complex bluff bodies and with complex aero-acoustic behaviour. The author summarizes all those works, including studies only available in Japanese up to now, in this review paper. After discussing the details of the FDLBM proposed by the author, example results of simulating the Aeolian tone generated from a circular cylinder at the Mach number M = 0.7 are shown. Then, the scheme is expanded for moving bodies by combining with the Arbitrary Lagrangian Eulerian formulation. Using this moving mesh scheme, the author shows the simulation results of the very strong sound pressure generated by a high-speed train in a tunnel. For issues of sound propagation in compressible two-phase flows whose density ratio is high, the two-particle model is introduced. Also, techniques to reduce noise generation from the flow velocity and pressure at gas-liquid interfaces are shown. Finally, the scattering of sound waves by water droplets is discussed. In thick fog, the sound coming from a distance becomes faint due to the sound-scattering effects of micro water droplets. The author gives an example of successfully solving such an issue by the FDLBM. It is highly admirable that the author developed the new FDLBM for aero-acoustic issues and has summarized it with sub-schemes to overcome several difficulties of engineering aeroacoustics in this review. It will certainly contribute to further development of fluid dynamics through computational aero-acoustics. Consequently, this paper was selected as the winner of the sixth FDR prize.

    Full Text Available During the 6th September 2002 earthquake the highest damage level in Palermo was observed in the SE sector. This is a recent urbanization area where reinforced concrete structures predominate. A detailed analysis of soil properties in Palermo was carried out by City-GIS to investigate a possible role of nearsurface geology on earthquake effects. City-GIS is a tool dedicated to natural hazard evaluation in urban areas. The availability of high density of well log data (stratigraphic and geotechnical allowed a realistic modeling of surface geology and physical-mechanical properties that control the seismic response. In wide zones of the above mentioned sector of Palermo, outcropping terrains are composed of thin calcarenite layers, lying above remarkably thick siltyclayey sands that overlay the Numidian Flysch, commonly considered the bedrock of Quaternary sediments. Since silty-clayey sands feature greater deformability properties (Young's modulus and smaller resistance properties (undrained cohesion and shear resistance angle than Numidian Flysch, these zones of the SE sector exhibit high values of the acoustic impedance contrast. Moreover, a quite wide portion of the study area, crossed by the Oreto River, is characterized by very thick alluvial deposits. Here, the significant lateral variations of the lithostratigraphic geometry may be an additional cause of strong site effects.

    There are rare times in astronomy when a celestial event, visible in broad daylight, can be used to measure a fundamental parameter and inspire a globe full of school age students. The June 5th/6th transit of Venus was one such event. In celebration, nine astronomy postdocs from the Chilean mainland traveled to Easter Island to lead a series of astronomy outreach activities over three days, culminating in a transit-viewing event. Our team dubbed "Equipo Hetu'u" or "Team Star" in the Rapa Nui (Easter Island native) language spent two days giving astronomy talks and doing hands-on demonstrations at the Museo Antropologico P. Sebastian Englert. In the final day-and-a-half leading up to the transit, we visited the science classes in the majority of the schools on the island, in order to spread the message about the once-in-a-lifetime transit event, highlighting how we planned on using it to measure the distance to the Sun. We estimate over 25% 1500 people) of this remote island participated in one or more of our organized activities. Our experience with this project is an excellent lesson on how to organize, lead, and fully execute a major outreach endeavor that inspires hundreds with minimal resources (save the spectacular event provided by the cosmos).

    This report presents an overall and summarizing report of most relevant findings and conclusions regarding the topic of 'Integration of more Distributed Energy Resources (DER) in the electricity supply of Europe' addressed in the 6th Framework Programme RTD project SOLID-DER. More precisely this report reviews the current position of DER, thereby enhancing its definition in RES and DG) in the electricity supply, drivers for more DER in the future and the different technical and economic barriers to meet these policy objectives in the EU countries. But most attention is given to the different technical, economic and regulatory changes and policies for increasing the share of DER (RES and DG) in the power supply of all EU countries in the next decades. Also for that reason, at the end the report the most recent developments and issues, i.e. the increasing role of intermittent RES and DG generation and their system impacts that need to be reduced in the future to maintain the reliability levels of the power system, are discussed in this report. This discussion is mainly based on recently finished or still on-going EIE EU projects such as RESPOND, IMPROGRES etc. Finally in the report the policy measures, regulation and the pending RTD issues necessary to be solved are summarized.

    Full Text Available Com o objetivo de conhecer a distribuição dos planorbídeos na sexta Região Administrativa do Estado de São Paulo, Brasil, com sede na cidade de Ribeirão Preto, foram realizadas, durante sete meses, coletas de moluscos em ambientes hídricos de toda área. Foi verificado que os planorbídeos mais comuns no território, por ordem de freqüência são: Drepanotrema lucidum, Biomphalaria intermedia, Biomphalaria peregrina e Biomphalaria tenagophila. A última espécie ocorre em poucos criadouros mas vem sendo responsabilizada pela transmissão natural da esquistossomose em Bebedouro, desde 1976. B.straminea prolifera em um córrego no município de Serrana e, em uma vala, de Ribeirão Preto. Os dados epidemiológicos e o baixo número de hospedeiros intermediários encontrados levam a crer que a possibilidade da doença disseminar-se pela região é pequena.A systematic survey was carried out in the area of the 6th Administrative Region of the State of S.Paulo, in order to discover the distributional patterns of planorbidic snails. Biomphalaria tenagophila is incriminated as the intermediary of Schistosoma mansoni in Bebedouro county where some human cases of the disease have been observed since 1976. Biomphalaria straminea lives at two breeding places - in Serrana and Ribeirão Preto. It is concluded that there is little possibility of schistosomiasis spreading in the studied area.

  8. Comparison of the updated solutions of the 6th dynamic AER Benchmark - main steam line break in a NPP with WWER-440

    International Nuclear Information System (INIS)

    The 6th dynamic AER Benchmark is used for the systematic validation of coupled 3D neutron kinetic/thermal hydraulic system codes. It was defined at The 10th AER-Symposium. In this benchmark, a hypothetical double ended break of one main steam line at full power in a WWER-440 plant is investigated. The main thermal hydraulic features are the consideration of incomplete coolant mixing in the lower and upper plenum of the reactor pressure vessel and an asymmetric operation of the feed water system. For the tuning of the different nuclear cross section data used by the participants, an isothermal re-criticality temperature was defined. The paper gives an overview on the behaviour of the main thermal hydraulic and neutron kinetic parameters in the provided solutions. The differences in the updated solution in comparison to the previous ones are described. Improvements in the modelling of the transient led to a better agreement of a part of the results while for another part the deviations rose up. The sensitivity of the core power behaviour on the secondary side modelling is discussed in detail (Authors)

    2010-05-01

    The Tsallis-based non-extensive statistics has been becoming a fruitful method to analyze complexity in time series. A magnitude distribution law, different from the Gutenberg-Richter relationship, was developed by Sotolongo-Costa and Posadas (2004), and later refined by Silva et al. (2006), by means of applying the non-extensivity concept. Using this law, the analysis of the magnitude distribution of the 2005-2009 seismicity of L'Aquila area (Central Italy), struck by a strong earthquake (ML=5.8) on April 6th 2009 (1:32 UTC), was performed. This was the strongest event of the sequence. The analysis of the frequency magnitude distribution of three time intervals - (1) from April 16, 2005 to March 30, 2009, (2) from March 30, 2009 to April 6, 2009, and (3) from April 6, 2009 to July 1, 2009- reveals that the nonextensivity parameter q increases in the seismic interval (2), before the occurrence of the strongest L'Aquila event, indicating an increase of the degree of out-of-equilibrium state before the occurrence of the strongest event.

    2012-01-01

    In the spirit of historic astronomical endeavors, we invited school groups across the globe to collaborate in a solar distance measurement using the rare June 5/6th transit of Venus. In total, we recruited 19 school groups spread over 6 continents and 10 countries to participate in our Hetu'u Global Network. Applying the methods of French astronomer Joseph-Nicolas Delisle, we used individual second and third Venus-Sun contact times to calculate the distance to the Sun. Ten of the sites in our network had amiable weather; 8 of which measured second contact and 5 of which measured third contact leading to consistent solar distance measurements of 152+/-30 million km and 163+/-30 million km respectively. The distance to the Sun at the time of the transit was 152.25 million km; therefore, our measurements are also consistent within 1sigma of the known value. The goal of our international school group network was to inspire the next generation of scientists using the excitement and accessibility of a rare astronom...

  11. Changes in Student Science Interest from Elementary to Middle School

    Science.gov (United States)

    Coutts, Trudi E.

    This study is a transcendental phenomenological study that described the experience of students’ interest in science from elementary school through middle school grades and the identification of the factors that increase or decrease interest in science. Numerous researchers have found that interest in science changes among children and the change in interest seems to modulate student motivation, which ultimately leads to fewer children choosing not only science classes in the future but science careers. Research studies have identified numerous factors that affect student interest in science; however, this study incorporated the lived experience of the child and looked at this interest in science through the lens of the child. The study design was a collective cross-case study that was multi-site based. This study utilized a sample of children in fifth grade classes of three different elementary schools, two distinct seventh grade classes of different middle schools, and ninth grade children from one high school in the State of Illinois. The phenomenon was investigated through student interviews. The use of one-on-one semi-structured interviews limited to 45 minutes in length provided the researcher with data of each child’s description of science interest. All interviews were audio- recorded and transcribed verbatim. The data was collected and analyzed in order to identify themes, and finally checked for validity. The most significant findings of this study, and possible factors contributing to science interest in children as they progress from elementary to high school, were those findings relating to hands-on activities, the degree to which a student was challenged, the offering of new versus previously studied topics in the curriculum, the perceived relevance of the curricular materials to personal life, and the empowerment children felt when they were allowed to make choices related to their learning experiences. This study’s possible implications for practitioners, specifically the findings of this study’s relation to the 2011 National Research Council Science Framework and the forthcoming Common Core Science Standards, were examined. This study concluded with discussion of its limitations, a summary of the results, and recommendations for additional areas of investigation of the subject matter.

  12. Graded gauge theory

    International Nuclear Information System (INIS)

    The mathematical background for a graded extension of gauge theories is investigated. After discussing the general properties of graded Lie algebras and what may serve as a model for a graded Lie group, the graded fiber bundle is constructed. Its basis manifold is supposed to be the so-called superspace, i.e. the product of the Minkowskian space-time with the Grassmann algebra spanned by the anticommuting Lorentz spinors; the vertical subspaces tangent to the fibers are isomorphic with the graded extension of the SU(N) Lie algebra. The connection and curvature are defined then on this bundle; the two different gradings are either independent of each other, or may be unified in one common grading, which is equivalent to the choice of the spin-statistics dependence. The Yang-Mills lagrangian is investigated in the simplified case. The conformal symmetry breaking is discussed, as well as some other physical consequences of the model. (orig.)

  18. Black holes and elementary particles

    International Nuclear Information System (INIS)

    By attributing an intrinsic quantum friction coefficient to particles, these can be defined to have an internal temperature which is expressed in terms of h (Planck constant), k (Boltzmann constant) and m (mass), much in the same way as the Hawking's temperature of a black hole does. Black holes are, therefore, considered as ''elementary'' particles in the gravitational universe, and some arguments in favour of this assumption are given. (author)

  12. On Elementary Loops of Logic Programs

    CERN Document Server

    Gebser, Martin; Lierler, Yuliya

    2010-01-01

    Using the notion of an elementary loop, Gebser and Schaub refined the theorem on loop formulas due to Lin and Zhao by considering loop formulas of elementary loops only. In this article, we reformulate their definition of an elementary loop, extend it to disjunctive programs, and study several properties of elementary loops, including how maximal elementary loops are related to minimal unfounded sets. The results provide useful insights into the stable model semantics in terms of elementary loops. For a nondisjunctive program, using a graph-theoretic characterization of an elementary loop, we show that the problem of recognizing an elementary loop is tractable. On the other hand, we show that the corresponding problem is {\\sf coNP}-complete for a disjunctive program. Based on the notion of an elementary loop, we present the class of Head-Elementary-loop-Free (HEF) programs, which strictly generalizes the class of Head-Cycle-Free (HCF) programs due to Ben-Eliyahu and Dechter. Like an HCF program, an HEF progra...

    We consider the univalence superselection rule. One would say perhaps ``There is no indication in nature to invalidate this rule. Fermions do not condensate!'' To explain our motivation, let us recall the correspondence of fermion systems and Pauli systems by the Jordan-Wigner transformation. For a finite lattice, fermion grading symmetry corresponds to the Pauli grading. For an infinite lattice, the Pauli-grading can be spontaneously broken e.g. for the XY-model. What is th...

    Mazen Shahin

    2010-06-01

    Full Text Available In this paper we will present the methodology and pedagogy of Elementary Mathematical Modeling as a one-semester course in the liberal arts core. We will focus on the elementary models in finance and business. The main mathematical tools in this course are the difference equations and matrix algebra. We also integrate computer technology and cooperative learning into this inquiry-based learning course where students work in small groups on carefully designed activities and utilize available software to support problem solving and understanding of real life situations. We emphasize the use of graphical and numerical techniques, rather than theoretical techniques, to investigate and analyze the behavior of the solutions of the difference equations.As an illustration of our approach, we will show a nontraditional and efficient way of introducing models from finance and economics. We will also present an interesting model of supply and demand with a lag time, which is called the cobweb theorem in economics. We introduce a sample of a research project on a technique of removing chaotic behavior from a chaotic system.

  5. Implementation of the obligations of the Convention on Nuclear Safety - 6th national report of Switzerland to the Convention in accordance with its article 5

    International Nuclear Information System (INIS)

    After a short description of Switzerland as a state in the middle of Europe and of its political organization, the report explains the development of the nuclear power from the first experimental reactor in 1957. Presently five nuclear power plants (NPP) are operating in Switzerland, producing about 40% of the electricity consumption of the country, the rest being produced essentially by hydroelectric plants. As the first regulatory authority, the Swiss Federal Nuclear Safety Commission was set up in 1960, which evolved to the Swiss Nuclear Safety Inspectorate (ENSI). Switzerland signed the Convention on Nuclear Safety (CNS) which came into force at the end of 1996. Since there, Switzerland has prepared and submitted the country reports for the regular Review Meetings of Contracting Countries. This 6th report by ENSI provides an update on compliance with CNS obligations. It gives consideration to issues that aroused particular interest at the 5th meeting and at the extraordinary meeting dedicated to the consequences of the accident at Fukushima Daiichi. Shortly after the accident at Fukushima Daiichi, the Swiss government has decided to phase out nuclear energy; existing plants will continue to operate as long as they are safe. In Switzerland, on-going activities regarding safety assessment of the different stages in the lifetime of nuclear installations consist of periodic assessments and assessments of long-term operation for existing Swiss NPPs. Such assessments have been performed for two Swiss NPPs (Beznau NPP and Muehleberg NPP) which have been in commercial operation for over 40 years. A detailed examination demonstrated that the conditions for the taking out of service of an NPP are not and will not be reached by these two plants within the next 10 years. Nevertheless, it is mandatory to continue with the scheduled ageing management, maintenance and backfitting activities. After the Fukushima accident, additional safety reviews were performed. All Swiss NPPs were required to back-fit two additional external feed options to resupply spent fuel pools with coolant. An external storage facility at Reitnau has been in place since June 2011, containing various operational resources for emergencies that can readily be called up. Mobile accident management equipment stored on-site has been significantly upgraded. In conclusion, all Swiss NPPs have undergone the safety review process required under the Convention and have incorporated the improvements identified in the respective safety review reports. The Swiss policy of continuous improvement to NPPs based on the current state of the art of science and technology ensures a high level of safety

  6. Redox-active phases and radionuclide equilibrium valence state in subsurface environments – New insights from 6th EC FP IP FUNMIG

    International Nuclear Information System (INIS)

    Within the 6th EC FP Integrated Project “Fundamental Processes of Radionuclide Migration” (FUNMIG), progress has been made to improve knowledge about the phases and reaction mechanisms involved in complex reduction processes of radionuclide contaminants in natural subsurface environments. This review paper gives an overview of the achievements made by the research groups involved in this project, and puts the scope and results of the studies in a more global context. Firstly, both thermodynamic and experimental evidence show that green rust is present and reactive in subsurface groundwater with a composition that spans the Fe(II)/Fe(III) redox boundary. Green rust has been shown to reduce Np(V), Se(VI) and Se(IV), but the pathways for the redox processes and the reaction products that result are complicated, and change as a function of the reaction parameters. Secondly, considerable evidence has emerged that Se(IV) is reduced on Fe(II)-bearing minerals which are ubiquitous in subsurface environments. The stable Se valence state in the presence of FeS2 has been shown to be Se(0). Also, natural dissolved humic substances that contain sufficient electron donating capacity are capable of interacting with, and possibly reducing, Se(IV) to lower valence states. Thirdly, the influence of HCO3- and organic ligands on the uptake and reduction of U(VI) on Fe(II)-bearing minerals was investigated. While it appeared that HCO3-3- decreased the extent of U(VI) uptake by the reducing surface, the fraction of reduced U(IV) in the solid phase increased with increasing HCO3- concentration. In contrast with the observations for HCO3-, organic ligands decreased both the extent of U uptake, as well as the fraction of U(IV) found in the solid phase. The studies performed within FUNMIG show that investigating reduction-oxidation mechanisms require (1) a detailed control over reaction conditions (anoxic atmosphere, purification of solid phases, initial radionuclide speciation), (2) a rigorous follow-up of reaction products (both solution chemistry and spectroscopic methods), and (3) the consideration of slow kinetics in the setting up of an experiment. These requirements make the study and assessment of redox processes one of the most demanding scientific challenges for geochemists who are asked to make predictions for radionuclide transport behaviour in the environment.

    Full Text Available Early childhood professional organizations support teachers as the best assessors of students’ academic, social, emotional, and physical development. This study investigates the predictive nature of teacher ratings of first-grade students’ performance on a standards-based curriculum-embedded performance assessment within the context of a state accountability system. The sample includes 4292 elementary school students cross-classified by 131 first-grade and 137 third-grade schools attended. This study uses extant statewide assessment data for students located in a state in the southeastern part of the United States. Controlling for student and school demographic variables in cross-classified random effects multilevel models, first-grade teacher ratings—as reflected by domain scores on a performance assessment—are found to positively and significantly correlate with students’ third-grade academic achievement.

    In this study, optical and thermal properties of normal grade and winter grade palm oil biodiesel were investigated. Surface Plasmon Resonance and Photopyroelectric technique were used to evaluate the samples. The dispersion curve and thermal diffusivity were obtained. Consequently, the variation of refractive index, as a function of wavelength in normal grade biodiesel is faster than winter grade palm oil biodiesel, and the thermal diffusivity of winter grade biodiesel is higher than the thermal diffusivity of normal grade biodiesel. This is attributed to the higher palmitic acid C16:0 content in normal grade than in winter grade palm oil biodiesel. PMID:21731429

    Full Text Available One of the greatest challenges of an elementary school teacher is equipping students with comprehension strategies that transfer to all content areas. With stable levels of reading achievement over the last two decades in the United States, it is necessary that further research be conducted on methods of increasing students’ comprehension proficiencies. This experimental research study explores the use of an anticipatory reading guide with third grade struggling readers across multiple subject areas. Findings indicate that the experimental treatment group outperformed the control group by a statistically significant rate on both reading and content area measures, indicating that when struggling readers practice and use strategies to explicitly think what will be asked of them after reading the passage they perform at higher levels.

    This study examines how STEM (science, technology, engineering, and mathematics) inquiry-based learning through a hands-on engineering design can be beneficial in helping students acquire academic vocabulary. This research took place in a second grade dual- language classroom in a public, suburban elementary school. English language learners, students who speak Spanish at home, and native English speakers were evaluated in this study. Each day, students were presented with a general academic vocabulary focus word during an engineering design challenge. Vocabulary pre-tests and post-tests as well as observation field notes were used to evaluate the student's growth in reading and defining the focus academic vocabulary words. A quiz and KSB (knowledge and skill builder) packet were used to evaluate students' knowledge of science and math content and engineering design. The results of this study indicate that engineering design is an effective means for teaching academic vocabulary to students with varying levels of English proficiency.

    The purpose of this study was to gain a greater understanding of how teachers talk in elementary science classrooms and how that talk assists students in making meaning of science. A premise of this study was the recognition of the importance of the goal of scientific literacy for students. Individuals who are scientifically literate have more opportunities for employment and the potential for an improved quality of life. The process of educating students in scientific literacy begins in elementary school, thus underscoring the importance of quality elementary science education. Using socio-cultural theory and the role of social languages in classrooms as a lens, this study explored the role of teacher talk in the development of student understanding in science. The literature review identified three areas of instruction that were relevant to the teaching of science. The three areas were patterns of teacher talk (IRE/IRF), the authoritative/dialogic continuum and the development of everyday/academic language. The research questions aligned with these three areas focusing on control of talk in classrooms as evidenced through patterns of talk and the development of the academic language of science. Two fourth grade teachers were observed during science instruction and the transcripts of their talk was used for data analysis. Data analysis generated quantitative and qualitative data sets. The results showed that language played two different roles in assisting students construct an understanding of science. The primary use of language by one teacher was the transmission of science content and checking student understanding. The other teacher viewed language as important for both teacher and students; using language as an instructional device to further student understanding.
