    This report discusses Test Campaign TC11 of the Kellogg Brown & Root, Inc. (KBR) Transport Gasifier train with a Siemens Westinghouse Power Corporation (Siemens Westinghouse) particle filter system at the Power Systems Development Facility (PSDF) located in Wilsonville, Alabama. The Transport Gasifier is an advanced circulating fluidized-bed gasifier designed to operate as either a combustor or a gasifier in air- or oxygen-blown mode of operation using a particulate control device (PCD). Test run TC11 began on April 7, 2003, with startup of the main air compressor and the lighting of the gasifier start-up burner. The Transport Gasifier operated until April 18, 2003, when a gasifier upset forced the termination of the test run. Over the course of the entire test run, gasifier temperatures varied between 1,650 and 1,800 F at pressures from 160 to 200 psig during air-blown operations and around 135 psig during enriched-air operations. Due to a restriction in the oxygen-fed lower mixing zone (LMZ), the majority of the test run featured air-blown operations.

    The Zr coating and Zr-Er coating are grown on TC11 substrate by double-glow plasma surface metallurgy technique, followed by the wear tests at ambient temperature and 500 °C. The data of nanohardness and elastic modulus of the samples are collected by the nano-indentation test. The adhesion strength of coatings is investigated by means of the scratch test. The study of wear resistance is performed using a ball-on-disc wear test system by running against the Si3N4 ball and measured by scanning electron microscope (SEM) and X-ray diffraction (XRD). Experimental results indicate that the nanohardness of the Zr coating and Zr-Er coating are 5.94 GPa and 7.98 GPa, respectively, which are 1.79 times and 2.41 times greater than that of TC11 substrate. Zr coating and Zr-Er coating realize the metallurgical bonding with TC11 substrate with continuous and compact structure. Compared with the Zr coating and TC11, the Zr-Er coating presents the lowest specific wear rates, which are 1.689 × 10-6 mm3 Nm-1 and 1.851 × 10-6 mm3 Nm-1 at ambient temperature and 500 °C respectively, indicating the excellent and improved wear resistance of TC11.

    Full Text Available Despite the recent advances in the treatment of multiple myeloma (MM, MM patients with high-risk cytogenetic changes such as t(4;14 translocation or deletion of chromosome 17 still have extremely poor prognoses. With the goal of helping these high-risk MM patients, we previously developed a novel phthalimide derivative, TC11. Here we report the further characterization of TC11 including anti-myeloma effects in vitro and in vivo, a pharmacokinetic study in mice, and anti-osteoclastogenic activity. Intraperitoneal injections of TC11 significantly delayed the growth of subcutaneous tumors in human myeloma-bearing SCID mice. Immunohistochemical analyses showed that TC11 induced apoptosis of MM cells in vivo. In the pharmacokinetic analyses, the Cmax was 2.1 μM at 1 h after the injection of TC11, with 1.2 h as the half-life. TC11 significantly inhibited the differentiation and function of tartrate-resistant acid phosphatase (TRAP-positive multinucleated osteoclasts in mouse osteoclast cultures using M-CSF and RANKL. We also revealed that TC11 induced the apoptosis of myeloma cells accompanied by α-tubulin fragmentation. In addition, TC11 and lenalidomide, another phthalimide derivative, directly bound to nucleophosmin 1 (NPM1, whose role in MM is unknown. Thus, through multiple molecular interactions, TC11 is a potentially effective drug for high-risk MM patients with bone lesions. The present results suggest the possibility of the further development of novel thalidomide derivatives by drug designing.

  5. Determination of interfacial heat transfer coefficient for TC11 titanium alloy hot forging

    2017-10-01

    In this paper, based on self-developed experimental apparatus, the upsetting test of TC11 titanium alloy on the hot flat die was conducted and Beck's nonlinear inverse estimation method was adopted to calculate the interfacial heat transfer coefficient (IHTC) and the change rules of IHTC following billet deformation rate, average interfacial temperature and holding time were investigated respectively. Experimental results indicate that IHTC increases with the increase of deformation rate as a whole, and the billet deformation heat and interfacial friction heat during forming that remarkably contribute to IHTC and the contributions by heat conduction to IHTC is differ from that by friction; the glass lubricant coated on the billet surface that weakens the heat transfer situation in the early stage of forging, however, this blocking effect of lubricant on IHTC soon vanishes with increasing deformation rate and it enhances the interface heat transfer later; the average interfacial temperature impacts on IHTC in many aspects and a high average interfacial temperature IHTC corresponds to a high IHTC when the deformation rate is certain, but this changing trend is not monotonous; the IHTC decreases with the increase of holding time due to oxidation. After certain holding time, the IHTC is only related to temperature and pressure in the absence of deformation rate, and the influence of pressure on IHTC is larger than that of temperature on it.

    2016-09-01

    Full Text Available The tool coating and cooling strategy are two key factors when machining difficult-to-cut materials such as titanium alloy. In this paper, diamond coating was deposited on a commercial carbide insert as an attempt to increase the machinability of TC11 alloy during the turning process. An uncoated carbide insert and a commercial Al2O3/TiAlN-coated tool were also tested as a comparison. Furthermore, MQL was applied to improve the cutting condition. Cutting performances were analyzed by cutting force, cutting temperate and surface roughness measurements. Tool wears and tool lives were evaluated to find a good matchup between the tool coating and cooling strategy. According to the results, using MQL can slightly reduce the cutting force. By applying MQL, cutting temperatures and tool wears were reduced by a great amount. Besides, MQL can affect the tool wear mechanism and tool failure modes. The tool life of an Al2O3/TiAlN-coated tool can be prolonged by 88.4% under the MQL condition. Diamond-coated tools can obtain a good surface finish when cutting parameters and lubrication strategies are properly chosen.

  9. Historical Roots of International Biomedical and Health Informatics: The Road to IFIP-TC4 and IMIA through Cybernetic Medicine and the Elsinore Meetings.

    Kulikowski, C A

    2017-08-01

    Background: It is 50 years since the International Federation of Information Processing (IFIP) Societies approved the formation of a new Technical Committee (TC) 4 on Medical Information Processing under the leadership of Professor Francois Grémy, which was the direct precursor of the International Medical Informatics Association (IMIA). Objectives: The goals of this paper are to give a very brief overview of early international developments leading to informatics in medicine, with the origins of the applications of computers to medicine in the USA and Europe, and two meetings - of the International Society of Cybernetic Medicine, and the Elsinore Meetings on Hospital Information Systems-that took place in 1966. These set the stage for the formation of IFIP-TC4 the following year, with later sponsorship of the first MEDINFO in 1974, setting the path for the evolution to IMIA. Methods: This paper reviews and analyzes some of the earliest research and publications, together with two critical contrasting meetings in 1966 involving international activities in what evolved into biomedical and health informatics in terms of their probable influence on the formation of IFIP-TC4. Conclusion: The formation of IFIP-TC 4 in 1967 by Francois Grémy arose out of his concerns for merging, at an international level, the diverse strands from the more abstract work on cybernetic medicine and its basis in biophysical and neural modeling, with the more concrete and health-oriented medical information processing that was developing at the time for hospitals and clinical decision-making.

    The distribution of residual lattice strain as a function of depth were carefully investigated by synchrotron-based high energy X-ray diffraction (HEXRD) in TC11 titanium alloy after laser shock peening (LSP). The results presented big compressive residual lattice strains at surface and subsurface, then tensile residual lattice strains in deeper region, and finally close to zero lattice strains in further deep interior with no plastic deformation thereafter. These evolutions in residual lattice strains were attributed to the balance of direct load effect from laser shock wave and the derivative restriction force effect from surrounding material. Significant intergranular stress was evidenced in the processed sample. The intergranular stress exhibited the largest value at surface, and rapidly decreased with depth increase. The magnitude of intergranular stress was proportional to the severity of the plastic deformation caused by LSP. Two shocks generated larger intergranular stress than one shock.

  12. Eighth Grade Algebra Course Placement and Student Motivation for Mathematics

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

    2016-01-01

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

    Full Text Available The paper considers the main results and some educational implications of the TIMSS 2003 assessment conducted in Serbia in the fields of the science achievement of Serbian eighth grade students and the science curriculum context of their achievement. There were 4264 students in the sample. It was confirmed that Serbian eighth graders had made average scale score of 468 points in the science, and with this achievement they are placed in the zone of the top of low international benchmarking level, very close to the point of intermediate benchmark. The average science achievement of the Serbian eighth graders is somewhat below the general international science achievement. The best results were achieved in the science content domain of "chemistry", and the lower results in the content domain of "environmental science". Across the defined science cognitive domains, it was confirmed that the Serbian students had achieved the best results in cognitive domain of "factual knowledge" and weaker results in "reasoning and analysis". The achieved results raise many questions about contents of the science curriculum in Serbia, its overall quality and basic characteristics of its implementation. These results can be eligibly used to improve the science curricula and teaching in Serbian primary school. .

    Neurovascular compression syndrome (NVCS) involves neuropathy due to intracranial blood vessels compressing the cranial nerves. NVCS of the eighth cranial nerve is less reportedly established as a clinical entity than that of the fifth and seventh cranial nerves. We report 17 cases of NVCS of the eighth cranial nerve and their clinical features. Clinical symptoms and test findings among our subjects indicated that most were aged more than 65 years, were unilateral, had intermittent tinnitus, suffered attacks lasting a few seconds dozens of times a day, experienced dizziness concomitantly with tinnitus, aggravated tinnitus and dizziness when tilting the head toward the affected side and looking downward (positional tinnitus, positional dizziness), heard specific tinnitus sounds such as crackling differing from those in cochlear tinnitus, had mild or no hearing loss, were diagnosed with retrocochlear hearing disturbance due to an interpeak latency delay between waves I and III of the auditory brainstem response (ABR), often had no nystagmus or canal paresis (CP), were found in constructive interference steady state magnetic resonance imaging (CISS MRI) to have compression of the eighth cranial nerve by the vertebral artery (VA) or the anterior inferior cerebellar artery (AICA), rarely had concomitant facial spasms, and had tinnitus and dizziness markedly suppressed by carbamazepine. With the number of elderly individuals continuing to increase, cases of NVCS due to arteriosclerotic changes in cerebral blood vessels are expected to increase, making it necessary to consider NVCS in elderly subjects with dizziness, tinnitus, and hearing loss.

    2003-09-01

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

  8. Teacher Tweets Improve Achievement for Eighth Grade Science Students

    2013-02-01

    Full Text Available In the Digital Age teachers have fallen far behind the technical skills of their "digital native" students. The implementation of technology as a tool for classroom communication is foreign for most teachers, but highly preferred by students. While teenagers are using Facebook, Twitter, and other social networks to communicate, teachers continue to respond through face-to-face conversations, telephone calls, and email messaging. Twitter, a platform for short message service text, is an online social network site that allows users to send and receive messages using 140 characters or less called Tweets. To analyze the relationship of the teacher's use of Twitter with student academic achievement, a correlation study conducted by Bess collected data from two matched samples of eighth grade science students: one utilizing Twitter and one not utilizing Twitter to reinforce classroom instruction. Two tests matching the science standards were given to both samples of students. The results of the tests were used as primary data. The findings suggested a positive correlation between the use of Twitter and student performance on the standardized tests. Implications for this study indicate that young teenagers may prefer Twitter as a mode of communication with their teacher, resulting in higher academic achievement in a middle school science class.

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

    2015-01-01

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

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

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

    Science.gov (United States)

    Friend, Jennifer Ingrid

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

    2016-01-01

    In this book a collection of the lecture notes given during the Eighth European Summer School on Experimental Nuclear Astrophysics is given. The school, whose first edition was first held in 2003, took place from 13 to 20 of September 2015 in Santa Tecla, a small village about 15 km north of Catania, characterized by its position on the volcanic shores of the Ionian Sea, surrounded by the spectacular “Timpa” area, a green protected park specific for its mediterranean vegetation. 80 young students and researchers from more than 20 countries attended the lectures and were also encouraged to present their work and results. The school, has tried once more to present to the young students the global picture of nuclear astrophysics research in the last years. Thus the scientific program of the school covered a wide range of topics dealing with various aspects of nuclear astrophysics, such as stellar evolution and nucleosynthesis, neutrino physics, the Big Bang, direct and indirect methods and radioactive ion beams. Nuclear astrophysics plays a key role in understanding energy production in stars, stellar evolution and the concurrent synthesis of the chemical elements and their isotopes. It is also a fundamental tool to explain the ashes of the early universe, to determine the age of the universe through the study of pristine stellar objects and to predict the evolution of the Sun or Stars. The “bone structure” for the above aspects is based on nuclear reactions, whose rates need to be determined in laboratories. Although impressive progress has been made over the past decades, which was rewarded by Nobel prizes, several open questions are still unsolved, which challenge the basis of the present understanding. A list of the lecture topics is given below: —Big Bang Nucleosynthesis —Stellar evolution and Nucleosynthesis —radioactive ion beams —detector and facilities for nuclear astrophysics —indirect methods in nuclear astrophysics —plasma physics An

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

    Full Text Available This paper considers the main results and some educational implications of the TIMSS 2003 assessment conducted in Serbia, in the fields of mathematics achievement of Serbian eighth grade students and the mathematics curriculum context of their achievement. It was confirmed that Serbian eighth graders have made average scale score of 477 points, and with this achievement they are placed in the zone of intermediate international benchmarking level. The average mathematics achievement of the Serbian eighth graders is somewhat above the average international mathematics achievement. The best result was achieved in the content domain of "algebra", and the lower result in the content domains of "measurement" and "data". In the defined cognitive domains the Serbian students have achieved the best results in "solving routine problems" and "knowing facts and procedures", and the weaker result in "reasoning". Statistically significant difference was found in the mathematics achievement between girls and boys in the Serbian TIMSS 2003 sample, so the girls’ average scale score was 480 points and the same value for the boys was 473 points. The achieved results raise many questions about the contents of mathematics curriculum in Serbia, its quality and basic characteristics of its implementation. These results can be eligibly used to improve the mathematics curriculum and teaching in Serbian primary school.

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

    Crim, Sharan R.

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

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

    This study investigated the effect of cooperative learning on eighth grade students' performance in algebra. 54 boys and 57 girls in four middle-school mathematics classes of Grade 8 in the UAE participated. Over a 3-wk. period, two classes (57 students) were taught using a cooperative learning method, and the other two classes (54 students) were taught using the traditional lecture method. Analysis of covariance using pretest scores as a covariant showed no statistically significant increase in the algebra performance for students in the cooperative learning groups compared with the traditional groups. However, boys in the cooperative setting improved significantly on the performance test compared with boys in the traditional setting.

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

    Bazopoulou-Kyrkanidou, E

    1992-03-01

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

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

    2016-05-01

    Full Text Available This action research study evaluated the effects of literacy strategies on academic achievement, motivation, and engagement of eighth-grade social studies students. Incorporating literacy strategies included teaching students to construct meaning, think critically, and build content knowledge, while stimulating their interests, using multiple texts and technology, and providing collaborative opportunities and high engagement during instructional activities. Students were divided into a literacy group and a direct instruction group with each class being taught the same content. Literacy strategies were incorporated in one class, and direct instruction activities were used in the other class. Results were determined using pre and posttest scores, a student motivation questionnaire, and a student engagement checklist. Results indicated significantly higher student achievement and engagement when literacy strategies were a part of the social studies instruction. Motivation also increased when literacy strategies were used. Literacy instruction was a beneficial strategy to improve student achievement, motivation, and engagement.

    2011-03-01

    Full Text Available This paper is a slightly edited version of a keynote lecture, delivered at the Aula Magna of the University of Barcelona as The Eighth Annual Doireann MacDermott Lecture, organized by the university’s Australian Studies Centre in December 2007. Offord’s essay takes us from Leonard Woolf’s creative and ethical intervention in Britain’s colonial project, forged through a transformative vision of the ‘spirit of place’ in his novel The Village in the Jungle (1931, to the Australian specifics of colonialism and its aftermath. Highly critical of the dominant power structures in Australian society that keep sustaining the Enlightenment discourse of an unfinished colonial project, Offord delineates alternative strategies so as to deal with identity and belonging, arguing for a notion/nation of ‘cultural citizenship’, no longer based on exclusions.

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

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

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

    Child and adolescent overweight is a serious health issue. Both snacking and television watching have been associated with childhood overweight, but the relationships have not been well examined in a multiethnic population. The aim of this study was to examine relationships between weekday television viewing, snack consumption, consumption of foods advertised on television, and overweight status of a multiethnic sample of fourth- and eighth-grade schoolchildren in Texas. This study is a secondary analysis of data from the School Physical Activity and Nutrition monitoring system, a validated survey with objective measures of height and weight. The sample of 11,594 children in the fourth and eighth grades was weighted to provide data representative of children in Texas public schools. Children were categorized on the basis of self-reported daily television viewing, snack consumption, and consumption of foods advertised on television. Multiple logistic regression was used to analyze, by grade level, the differences in the prevalence of overweight by category. Television viewing, frequency of snack consumption, and consumption of foods advertised on television were all positively related to one another. In general, both consuming more snacks and foods advertised on television were associated with reduced odds of overweight regardless of the amount of television watched. The results suggest that the relationships between weekday snacking behaviors and television viewing in a multiethnic population are complicated. When these behaviors are clustered, overweight status may be related more to the number of snacks consumed than to the amount of television watched. To determine the exact relationship, additional research, especially among Hispanic children, is warranted.

In the course of its integration into the EU, Turkey has been simultaneously facing access, quality, and equity issues in education. Over the past decade, substantial progress has been made on increasing the access. However, improving the country's low level of education quality and achieving equity in quality education across the regions continue to be a monumental challenge in Turkey. Most recently, results from the Trends in International Mathematics and Science Study (TIMSS) 2007 indicated that Turkey's educational achievement at the eighth grade, the end of compulsory primary education in Turkey, was far below that of other countries in the EU. Considering Turkey's long standing socioeconomic disparities between the western and eastern parts of the country, the challenges of improving overall education quality are coupled with the challenges of achieving equity in learning outcomes for students across the regions. This dissertation used data from TIMSS 2007 to document the extent of Turkey's regional differences in science achievement at the eighth grade and to investigate factors associated with these differences. Findings from a series of analyses using hierarchical linear models suggested that attempts to increase Turkish students' achievement and close the achievement gaps between regions should target the students in the undeveloped regions, particularly in Southeastern Anatolia and Eastern Anatolia. Designing interventions to improve competency in Turkish and to compensate for the shortcomings of insufficient parental education, limited home educational resources, poor school climate for academic achievement, and inadequate instructional equipment and facilities might be expected to close the regional achievement gaps as well as raise the overall achievement level in Turkey.

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

    Smyth, Carol Ann Mary

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

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

    Riedell, Kate Elizabeth

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

    IQ-SPECT, an add-on to general purpose cameras based on multifocal collimation, can reduce myocardial perfusion imaging (MPI) acquisition times to one-fourth that of standard procedures (to 12 s/view). In a phantom study, a reduction of the acquisition time to one-eighth of the standard time (to 6 s/view) was demonstrated as feasible. It remains unclear whether such a reduction could be extended to clinical practice. Fifty patients with suspected or diagnosed CAD underwent a 2-day stress-rest {sup 99m}Tc-sestamibi MPI protocol. Two consecutive SPECT acquisitions (6 and 12 s/view) were performed. Electrocardiogram-gated images were reconstructed with and without attenuation correction (AC). Polar maps were generated and visually scored by two blinded observers for image quality and perfusion in 17 segments. Global and regional summed stress score (SSS), summed rest score (SRS) and summed difference score (SDS) were determined. Left ventricular volumes and ejection fraction were calculated based on automated contour detection. Image quality was scored higher with the 12 s/view acquisition, both with and without AC. Summed scores were statistically comparable between the 6 s/view and the 12 s/view acquisition, both globally and in individual coronary territories (e.g. in images with AC, SSS were 6.6 ± 8.3 and 6.2 ± 8.2 with 6 s and 12 s/view, respectively, p = 0.10; SRS were 3.9 ± 5.6 and 3.5 ± 5.3, respectively, p = 0.19; and SDS were 2.8 ± 5.7 and 2.6 ± 5.7, respectively, p = 0.59). Both acquisitions allowed MPI-based diagnosis of CAD in 25 of the 50 patients (with AC). Calculated end-diastolic volume (EDV) and end-systolic volume (ESV) were modestly higher with the 6 s/view acquisition than with the 12 s/view acquisition (EDV +4.8 ml at rest and +3.7 ml after stress, p = 0.003; ESV +4.1 ml at rest and +2.6 ml after stress, p = 0.01), whereas the ejection fraction did not differ (-1.2 % at rest, p = 0.20, and -0.9 % after stress, p = 0.27).

    Australian eighth-grade mathematics lessons were shown by the 1999 TIMSS Video Study to use a high proportion of problems of low procedural complexity, with considerable repetition, and an absence of deductive reasoning. Using definitions from the Video Study, this study re-investigated this `shallow teaching syndrome' by examining the problems on three topics in nine eighth-grade textbooks from four Australian states for procedural complexity, type of solving processes, degree of repetition, proportion of `application' problems and proportion of problems requiring deductive reasoning. Overall, there was broad similarity between the characteristics of problems in the textbooks and in the Australian Video Study lessons. There were, however, considerable differences between textbooks and between topics within textbooks. In some books, including the best-selling textbooks in several states, the balance is too far towards repetitive problems of low procedural complexity.

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

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

    The Sloan Digital Sky Survey (SDSS) started a new phase in August 2008, with new instrumentation and new surveys focused on Galactic structure and chemical evolution, measurements of the baryon oscillation feature in the clustering of galaxies and the quasar Ly{alpha} forest, and a radial velocity search for planets around {approx}8000 stars. This paper describes the first data release of SDSS-III (and the eighth counting from the beginning of the SDSS). The release includes 5-band imaging of roughly 5200 deg{sup 2} in the Southern Galactic Cap, bringing the total footprint of the SDSS imaging to 14,555 deg{sup 2}, or over a third of the Celestial Sphere. All the imaging data have been reprocessed with an improved sky-subtraction algorithm and a final, self-consistent recalibration and flat-field determination. This release also includes all data from the second phase of the Sloan Extension for Galactic Understanding and Evolution (SEGUE-2), consisting of spectroscopy of approximately 118,000 stars at both high and low Galactic latitudes. All the more than half a million stellar spectra obtained with the SDSS spectrograph have been reprocessed through an improved stellar parameters pipeline, which has better determination of metallicity for high metallicity stars.

    Full Text Available The purpose of this study is to determine sixth, seventh and eighth grade students’ writing anxiety and dispositions and to examine to what extent they predict each other. The basis of this study is to determine whether writing disposition is the significant predictor of writing anxiety or not and whether students’ grade levels and genders are significant predictor of writing anxiety and dispositions or not. The research was designed according to survey model. The study group, selected through simple sampling method, is made up of 860 students studying at 6th, 7th and 8th grades in elementary schools of Şarkışla District, Sivas. While “Writing Anxiety Scale”, adapted into Turkish by Özbay and Zorbay (2011, was administered to determine the study group’s writing anxiety level, “Writing Disposition Scale”, adapted into Turkish by İşeri and Ünal (2010, was used to determine the writing disposition level. At the end of the study, it was found that writing disposition is a significant predictor of writing anxiety and students’ grade levels and genders are significant predictors of writing anxiety and dispositions. An education environment to create a strong writing disposition for students is recommended. Also, similar studies on different dimensions of the issue can be conducted.

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

    For the eighth time since 2005, the CERN School of Computing (CSC) has organised its inverted school, which will take place at CERN on 23 and 24 February 2015, in the IT Auditorium (Room 31/3-004).   The idea for inverted CSCs stemmed from the observation that at regular CSCs it is common to find students in the room who know more on a particular (advanced) topic than the lecturer. So why not try and exploit this and turn the students into teachers? CSC2014 students made proposals via an electronic discussion forum, from which a programme was designed. This year’s programme focuses on challenging and innovative topics, including: the evolution of processor architectures, the growing complexity of CPUs and its impact on the software landscape, exploring clustering and data processing, the importance of message passing in high-performance computing, the development of applications across heterogeneous systems. There will be also lectures on applied computing used in the simulation of lon...

    We report the discovery of a cold Super-Earth planet (mp=4.4±0.5 M⊙) orbiting a low-mass (M=0.23±0.03) M⊙ dwarf at projected separation a⊥=1.18±0.10 a.u., i.e., about 1.9 times the distance the snow line. The system is quite nearby for a microlensing planet, DL=0.86±0.09 kpc. Indeed, it was the large lens-source relative parallax πrel=1.0 mas (combined with the low mass M) that gave rise to the large, and thus well-measured, "microlens parallax" πE∝(πrel/M)1/2 that enabled these precise measurements. OGLE-2017-BLG-1434Lb is the eighth microlensing planet with planet-host mass ratio qturnover" in the mass function found by Suzuki et al. relative to the power law of opposite sign n=-0.93±0.13 at higher mass ratios q≳2×10-4. We combine our result with that of Suzuki et al. to obtain p=0.73+0.42-0.34.

    The eighth Joint Conference on Applications of Air Pollution Meteorology, held January 23-28, 1994, again brings together the American Meteorological Society and Air and Waste Management Association with a broader scientific community to examine the role of the atmosphere on current air quality issues. The CAA Amendments non-attainment title has brought renewed interest in the pairing of complex dynamical meteorological models with photochemical air quality models. Requirements that future attainment to regulations be demonstrated with these models invite a new look at model evaluation. The CAAA titles addressing air toxics have brought renewed interest in near-source dispersion and deposition of toxic chemicals. Consequently, this conference is divided into sessions focusing on topics related to these issues. They include: The Dispersion Environment; Meteorology in Emissions Determination; Long-Range and Mesoscale Pollutant Transport and Fate; Meteorology and Photochemistry; Advanced Dispersion Models and Modeling Systems; Topics in Model Evaluation; Complex Flow Affecting Dispersion Near Structures; and Coastal and Complex Terrain Issues Evaluation.

    Full Text Available In this study, eighth grade students’ motivations towards science learning in Turkey and Germany were determined and compared on the basis of countries. The sample of the research was consisted of 393 8th grade students of public schools in the city centre of Turkey/Adana and in Germany/Berlin who were selected through a basic random sample during the 2013-2014 education period. In the research in which the survey model was used “Science Motivation Questionnaire” as data collection tool. In the analysis of the sub-problems of the study, descriptive statistics like frequency (f-percentage (% and independent groups t-test were used. On the other hand, in the adaptation of the scale to the German, item analysis, exploratory factor analysis and Cronbach Alpha coefficient were performed. As a result of the factor analysis, we could accept the scale as compatible with the original form, acceptably reliable and valid. Since the items inside the Turkish and German forms indicated differences, mean scores were considered during the analysis of the sub-problems. Results exposed that there are differences between the total motivational scores of students and these differences were in favor of the students in Germany. Moreover, we confirmed that the distribution of total motivation scores of the male and female students in each country was close to each other

  4. THE ROLE OF THE BISHOPS OF ASIA MINOR IN THE DIFFUSION OF ICONOCLASM DURING THE EIGHTH CENTURY IN BYZANTIUM

    Directory of Open Access Journals (Sweden)

    Sergey Zaplatnikov

    2013-08-01

    Full Text Available This article is concerned with one of the most discussed problem in the history of Byzantium regarding the origin and circumstances of the appearance of iconoclasm in the eighth century. The author studies the contradiction between the early and later sources about the role of the bishops in Asia Minor in the diffusion of the iconoclastic heresy, particularly that of Bishop Constantine of Nacolea. The agenda of the Eighth Ecumenical Council, in which Constantine is described as the major heresiarch of iconoclasm, serve as a primary later source. On the other hand, earlier sources include the epistles of Germanos I of Constantinople, which indicate the Orthodoxy of this hierarch particularly regarding the icons and their veneration. An apparent contradiction in historiography is usually resolved by means of an examination of still another work of Germanos, his tractate On Heresies and the Councils, the contents of which directly prove the guilt of Constantine of Nacolea in diffusing the heresy. But an analysis of this work clearly shows that Germanos was not really its author. But, on the other hand, Constantine of Nicolea is deliberately portrayed in this work as the person responsible for the diffusion of the heresy, in order to absolve from guilt, the real perpetrators, the Emperors Leo III and Constantine V of the Isaurian Dynasty, the descendants of whom emerged as the initiators of the Eighth Ecumenical Council and, paradoxically, the victorious conquerors of the Iconoclastic Heresy

    Full Text Available Abstract Introduction We report the case of a patient with Churg-Strauss syndrome with eighth cranial nerve palsy. Vestibulocochlear nerve palsy is extremely rare in Churg-Strauss syndrome. To the best of our knowledge, only one case of complicated neuropathy of the eighth cranial nerve has been described in a previous report presenting an aggregate calculation, but no differentiation between polyarteritis nodosa and Churg-Strauss syndrome was made. High-dose immunoglobulin was administered to our patient, and her neuropathy of the eighth cranial nerve showed improvement. Case presentation At the age of 46, a Japanese woman developed Churg-Strauss syndrome that later became stable with low-dose prednisolone treatment. At the age of 52, she developed sudden difficulty of hearing in her left ear, persistent severe rotary vertigo, and mononeuritis multiplex. At admission, bilateral perceptive deafness of about 80dB and eosinophilia of 4123/μL in peripheral blood were found. A diagnosis of cranial neuropathy of the eighth cranial nerve associated with exacerbated Churg-Strauss syndrome was made. Although high doses of steroid therapy alleviated the inflammatory symptoms and markers, the vertigo and bilateral hearing loss remained. Addition of a high-dose immunoglobulin finally resulted in marked alleviation of the symptoms associated with neuropathy of the eighth cranial nerve. Conclusions A high dose of immunoglobulin therapy shows favorable effects in neuropathy of the eighth cranial nerve, but no reports regarding its efficacy in cranial neuropathy have been published.

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

    The design and construction of the smallest element of symmetry of a confined flood pattern, in reservoir simulation, requires the use of modifiers for the flow terms in the equations of all boundary blocks in that element. These modifiers are necessary to describe the appropriate block volume, production rate, well productivity index, transmissibility in the x-, y-, and z-directions, and others depending on the recovery process. While modifiers for block volume and production rate are straightforward, those for other terms of importance in the flow equation are not. Even though a limited number of researchers and users may be aware of these modifiers, evidence abounds that the majority of researchers and practicing engineers are not aware of such. This fact is not surprising since information about these modifiers has not been published in the literature. A comprehensive catalogue is presented of all modifiers necessary to simulate 1/8 of confined five- and nine-spot patterns. These modifiers are provided for all possible block configurations including triangular half-, quarter-, and one-eighth blocks and rectangular half- and quarter-blocks. The derivation of these modifiers has sound theoretical basis and is general in that it can be applied to other food patterns or to the formulation of other recovery processes. Also the validity is investigated of a commonly used 1/8 of a confined five-spot pattern where the apex cells at the three corners are combined with the blocks adjoining them. It is found that while the simulation of 1/8 of a confined pattern produces exactly the same performance as that based on the whole pattern, the commonly used 1/8 of a confined pattern does not. Furthermore, the simulation of the smallest element of symmetry is an order of magnitude more cost-effective than the simulation of 1/4 or 1/2 confined pattern. 11 figs., 19 refs., 3 tabs.

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

    Science.gov (United States)

    Seethaler, Sherry Lynn

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

    This qualitative study describes the experiences of a group of sixteen, eighth grade girls participating in a single-sex, math/science program based on gender equity research and constructivist theory. This phenomenological case study highlights the individual changes each girl perceives in herself as a result of her involvement in this program which was based at a suburban middle school just north of New York City. Described in narrative form is what took place during this single-sex program. At the start of the program the girls worked cooperatively in groups to build canoes. The canoes were then used to study a wetland during the final days of the program. To further immerse the participants into nature, the girls also camped during these final days. Data were collected from a number of sources to uncover, as fully as possible, the true essence of the program and the girls' experiences in it. The data collection methods included direct observation; in-depth, open-ended interviews; and written documentation. As a result of data collection, the girls' perceived outcomes and assessment of the program, as well as their recommendations for future math/science programs are revealed. The researcher in this study also acted as teacher, directing the program, and as participant to better understand the experiences of the girls involved in the program. Thus, unique insights could be made. The findings in this study provide insight into the learning of the participants, as well as into the relationships they formed both inside and outside of the program. Their perceived experiences and assessment of the program were then used to develop a greater understanding as to the effectiveness of this non-traditional program. Although this study echoed much of what research says about the needs of girls in learning situations, and therefore, reinforces previously accepted beliefs, it also reveals significant findings in areas previously unaddressed by gender studies.

    Parker, Carolyn Ann

    My study examined the experiences of eight seventh and eighth grade girls of Central American descent, in and out of the science classroom. The study was interpretive in design and explored the question, "How did the eight participants understand and make meaning of science?" Guided by a sociocultural perspective and a socially critical stance, I explored issues of educational access, particularly to science, mediated by the relationships and experiences formed by families, peers, science classrooms, schools, and society. Data sources included monthly individual interviews, regular focus group meetings, school observations, and interviews with teachers and family members. Findings include the importance of school science experiences that emphasize hands-on activities and the study of topics relevant to students' everyday lives. School influences that I discuss include English-as-a-Second Language learning, English language ability and its effect on classroom interactions, ability grouping, standardized testing, and teachers' instructional practices. Out-of-school influences I examine include the national science education reform movement, familial expectations, and society and the media's portrayal of science and the scientist. The implications and recommendations of the study are particularly germane to practice. Recommendations for the science classroom include a continued emphasis on hands-on science experiences that incorporate high academic expectations for all students, including second-language learners. Moreover, curriculum should be connected and relevant to students' everyday experiences. Recommendations for outside-the-science classroom include a thoughtful examination of the educational environment created by a school's tracking policy and continued support of meaningful professional development experiences for teachers. Future research and the subsequent development of theory should include a further analysis of the influence of gender, ethnicity

    Full Text Available Knowing students’ problems, especially in reading, is very important to design an appropriate and meaningful learning. From the problem identification, teacher can find the potency of designing and developing material to meet students’ need. Therefore, this study was aimed to identify the potentials and problems toward reading lesson faced by the eighth grade students of Junior High School. This study was based on the result of classroom observation, document study, and also checklists. The identification of potency and problems through classroom observation was done to obtain data on how existing reading material was used in teaching reading on the classroom. There was also document study to evaluate existing reading material and syllabus used for teaching reading. Then, the data from the teacher and students had been gathered by administering checklists. From the result of the study, it can be identified that the problems faced by the eighth grade students of Junior High School in reading dealt with topic selection, pictures or illustration, and reading activities, while the potency was to develop new reading material by using those problems as consideration.

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

    Roncke, Nancy

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

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

    Full Text Available The current article presents the results of a study that aimed to analyze the difficulties faced by eighth grade students when learning to solve algebraic problems based on linear equations with one unknown variable. The participants were learners with low average performance in mathematics at a high school in Heredia. The research followed a naturalistic paradigm and the case study method with a qualitative approach. Different techniques like class observations, questionnaires to students, non-structured interviews to teachers and interviews to the learners were applied. The research helped to identify the main causes of difficulty when learning to solve algebraic problems. Some of the causes that were identified are affective aspects, lack of previous knowledge, poor relational understanding, fatigue, diversion, reading deficiencies and misunderstanding of terminology.

  8. Representation of acoustic signals in the eighth nerve of the Tokay gecko. II. Masking of pure tones with noise.

    Sams-Dodd, F; Capranica, R R

    1996-10-01

    Acoustic signals are generally encoded in the peripheral auditory system of vertebrates by a duality scheme. For frequency components that fall within the excitatory tuning curve, individual eighth nerve fibers can encode the effective spectral energy by a spike-rate code, while simultaneously preserving the signal waveform periodicity of lower frequency components by phase-locked spike-train discharges. To explore how robust this duality of representation may be in the presence of noise, we recorded the responses of auditory fibers in the eighth nerve of the Tokay gecko to tonal stimuli when masking noise was added simultaneously. We found that their spike-rate functions reached plateau levels fairly rapidly in the presence of noise, so the ability to signal the presence of a tone by a concomitant change in firing rate was quickly lost. On the other hand, their synchronization functions maintained a high degree of phase-locked firings to the tone even in the presence of high-intensity masking noise, thus enabling a robust detection of the tonal signal. Critical ratios (CR) and critical bandwidths showed that in the frequency range where units are able to phaselock to the tonal periodicity, the CR bands were relatively narrow and the bandwidths were independent of noise level. However, to higher frequency tones where phaselocking fails and only spike-rate codes apply, the CR bands were much wider and depended upon noise level, so that their ability to filter tones out of a noisy background degraded with increasing noise levels. The greater robustness of phase-locked temporal encoding contrasted with spike-rate coding verifies a important advantage in using lower frequency signals for communication in noisy environments.

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

    The recent 2014 Evidence-Based Guideline for the Management of High Blood Pressure in Adults from the Eight Joint National Committee Panel may significantly affect the aging US population. We performed a cross-sectional analysis of black and white participants in Atherosclerosis Risk in Communities who participated in the fifth study visit (2011-2013). Sitting blood pressure was calculated from the average of 3 successive readings taken after a 5-minute rest. Currently, prescribed antihypertensive medications were recorded by reviewing medication containers brought to the visit. Blood pressure control was defined using both the Seventh and Eighth Joint National Committee thresholds. Of 6088 participants (mean age, 75.6 [range, 66-90] years, 58.4% women; 23.2% black), 54.9% had either diabetes mellitus or chronic kidney disease. The prevalence of hypertension according to Seventh Joint National Committee thresholds was 81.9%, and 62.8% of the entire sample were at blood pressure goal. Using the Eighth Joint National Committee thresholds, 79.4% were at blood pressure goal (16.6% were reclassified as at-goal). Reclassification was higher for individuals with diabetes mellitus or chronic kidney disease (20.6%) when compared with individuals without either condition (11.6%). The use of antihypertensive medications in our cohort was high, with 75.0% prescribed at least 1 antihypertensive medication and 46.7% on ≥2 antihypertensive agents. In conclusion, in a US cohort of aging white and black individuals, ≈1 in 6 individuals were reclassified as having blood pressure at goal by Eighth Joint National Committee guidelines. Despite these less aggressive goals, >20% remain uncontrolled by the new criteria. © 2015 American Heart Association, Inc.

    The change in TNM classification of malignant pleural mesothelioma (MPM) between the seventh and eighth edition classifications has resulted in the downstaging of many advanced-stage patients into pathological stage IB. Many mesotheliomas without lymph node metastasis have been classified as stage IB in the eighth edition classification. Stage IB mesotheliomas comprised a heterogeneous group with different prognosis. It is necessary to clarify the prognostic factors in this group. Between September 2009 and August 2016, a total of 89 patients with MPM underwent curative intent surgery [pleurectomy decortication n = 57 (64.1%), extrapleural pneumonectomy n = 32 (35.9%)] at our institution. Of these, 40 were reclassified as stage IB according to the eighth edition TNM classification. Independent unfavorable prognostic factors were identified by univariate analyses using the log-rank test and Cox proportional hazards regression models. Three independent significant factors were identified that indicated an unfavorable prognosis: a nonepithelioid subtype, lymphovascular invasion, and preoperative forced expiratory volume in 1 s (FEV1) < 2000 ml. Patients with no, one, and two of these risk factors showed 3-year overall survival probabilities of 94.7, 62.5, and 0%, respectively. The 3-year survival of patients with one factor did not differ significantly from that of patients with stage III MPM, whereas that of patients with two factors was significantly shorter (p = 0.015). Independent poor prognostic factors for patients with stage IB MPM patients, allowing subgroups with poorer and more favorable prognoses to be identified. This should help personalize decisions on adjuvant chemotherapy.

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

    The concept central to Canadian plans for nuclear waste disposal, a multibarrier system involving geologic media and engineered systems, is based on known technologies and current scientific knowledge and has gained strong international engineering and scientific support. Assessment of the disposal concept requires the development and application of radiological and risk criteria, an area in which the Technical Advisory Committee (TAC) considers the program to have been adopting a credible and acceptable approach. Progress continues to be made within the geoscience program, including extensive hydrogeological work and the development of methods for site characterization and evaluation. TAC deems the research done on fracture analysis and the geomechanical investigations to be of high quality. A document summarizing the combined research plan for geology, geophysics and hydrogeology is needed for overall assessment of the Flow System Study. Most of the geoscience effort is centered around the Underground Research Laboratory, a facility essential to building a realistic data base for the development and validation of the geosphere model. The work on recycle waste immobilization is essentially done, and progress continues to be made in research on used fuel charactierization and immobilization. TAC supports continued corrosion research on copper and titanium alloys. The organization and funding of the program provide some assurance that the research objectives will be met. The concept approvals process and the preparation of a concept assessment document should proceed without delay

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

    Full Text Available Introduction: Genetic resources in any country are valuable materials which needed to be conserved for a sustainable agriculture. An animal phenotype is generally affected by genetic and environmental factors. To increase mean performance in a population under consideration not only environmental conditions, but also genetic potential of the animals should be improved. Although, environmental improvement could increase the level of animals’ production in a more rapid way, it is not a permanent and non-cumulative progress. In any breeding schemes prediction breeding value of the candidate animals is needed to be obtained with a high precision and accuracy for making a remarkable genetic gain for the traits over the time. The main objective of the present research was to study accuracy of predicted breeding value for body weight at eighth week of age in indigenous chickens of Khorasan Razavi province. Materials and methods: A set of 47,000 body weight (at the age of eight weeks records belonging to 47,000 head of male and female chicks (progeny of 753 sires and 5,154 dams collected during seven generations (2006-2012 was used. The data were obtained in Khorasan Razavi native chicken breeding center. An animal model was applied for analyzing the records. In the model, contemporary group of generation*hatch*sex (GHS as a fixed effect, weight at birth as a covariable, as well as direct and maternal additive genetic random effects were taken into account. In an initial analysis using SAS software, all fixed and covariate factors included in the model were detected to be significant for the trait. All additive genetic relationships among the animals in the pedigree file (47,880 animals were accounted for. Variance and covariance components of direct and maternal additive genetic effects were estimated through restricted maximum likelihood (REML method. Breeding value of the animals was obtained by best linear unbiased prediction (BLUP. Selection

    The eighth tumor-node-metastasis (TNM) classification system for lung cancer has been used since January 2017 and must be applied to an individual institution's database. We analyzed pathological stage data of 2756 patients who underwent resection of non-small-cell lung cancer, particularly in terms of the degree of visceral pleural invasion and involved neighboring structures. Few patients had stage IIA disease (103, 4%); stratification between stages IB and IIA was insufficient (p = 0.129). When T2a tumors were divided into PL1 and PL2 subgroups based on the degree of pleural invasion, there was a significant prognostic difference between the subgroups (p consideration.

    (14C) is produced in the atmosphere by galactic cosmic rays, which are modulated by solar magnetic activity. Its content in tree rings is retained and provides a record of past cosmic ray intensity and solar activity. We have measured, with 2 year resolution, the 14C content in Japanese cedar tree rings for the period A.D. 600 to 760, which includes a small grand solar minimum in the seventh to eighth centuries. Periodicity analysis of the 14C data shows that there is a component in the frequency band of the Schwabe cycle, with a period of 12-13 years continuing throughout the minimum. This is the fourth case in which an increase in the length of the Schwabe cycle has been observed in a grand solar minimum, after the Maunder Minimum, the Spörer Minimum, and the Fourth Century B.C. Minimum.

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

    Ledger, Antoinette Frances

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

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

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

    Due to the fact that the internal carotid artery (ICA) is responsible for nourishing two thirds of the brain volume, our aim was to inspect the morphofunctional consequences of the bilateral lack of this artery. In order to examine this condition, we referred to both the library archive of our Faculty of Medicine and electronic databases of anatomical and clinical reports that included the following keywords: "absence," "aplasia," or "agenesis" in combination with "internal carotid artery," "common carotid artery," or only "carotid artery." We found 60 recorded cases of the bilateral ICA absence in the subjects of newborn status to the eighth decade of life, which had been discovered in 20 countries. The following ten parameters were described: the embryological base, terminology, history, incidence, general data, differential diagnosis, collateral circulation, the associated vascular aplasia and/or other variants, pathophysiology, and the importance in praxis. This review noted all the cases of the bilateral ICA aplasia published for the past 104 years. Although there were 11.6% of cases of the associated cerebral aneurysms and 1-4 cases of 16 other diseases, approximately one quarter of the cases was without any pathology.

    The first objective of this study was to investigate if the experimental students' post-test knowledge of nutrition and plant reproduction would be improved more significantly than that of their control group counterparts based on their treatment, attitudes to science, self-esteem, gender and socio-economic background. Treatment involved teaching the experimental students under three learning modes--pure cooperative, cooperative-competitive and individualistic whole class interpersonal competitive condition--using concept and vee mappings and the lecture method. The control groups received the same treatment but were not exposed to concept and vee mappings. This study's second objective was to determine which of the three learning modes would produce the highest post-test mean gain in the subjects' knowledge of the two biology concepts. The study's sample comprised 932 eighth graders (12-13-year-olds) in 14 co-educational comprehensive high schools randomly selected from two Jamaican parishes. An integrated science performance test, an attitudes to science questionnaire and a self-esteem questionnaire were used to collect data. The results indicated that the experimental students (a) under the three learning modes, (b) with high, moderate, and low attitudes to science, and (c) with high, moderate, and low self-esteem, performed significantly better than their control group counterparts. The individualist whole class learning mode engendered the highest mean gain on the experimental students' knowledge, while the cooperative-competitive learning mode generated the highest mean gain for the control group students.

    Using a guinea pig model of experimental endolymphatic hydrops, click sounds of altered polarity showed different latencies and amplitudes in hydropic compared with normal cochleae. Latency changes appeared as early as 1 week after endolymphatic obstruction. This method can help diagnose endolymphatic hydrops. The goal of the study was to develop an objective electrophysiological diagnosis of endolymphatic hydrops. Endolymphatic hydrops were created surgically in guinea pigs. The latency and the amplitude of the eighth cranial nerve compound action potential (CAP) for click sounds of altered polarity were measured up to 8 weeks after the surgery. At early stages after surgery, the latency for condensation clicks became longer, and at later stages the latencies for both condensation and rarefaction became longer. The discrepancy in the latencies for rarefaction and condensation click sounds (rarefaction minus condensation) became larger by the first week after surgery, but no further discrepancy occurred thereafter. Compared with latency changes, amplitude changes in the CAP were rapid and progressive following surgery, suggesting ongoing damage to hair cells.

    The main aim of this project is to perform a descriptive study about the levels of total mercury (Hg-T) and of methylmercury (Me-Hg) in scalp hair specimens of a selected human population of high risk in the Eighth Region of Chile, the group studied included pregnant women (PW), nursing women (NW) and preschool children residing in fishing villages distributed within the coastal zone of this region, the diets of the test group included fish and shellfish as main food components. The degree of Hg contamination of this population was compared to a control population (''core programme''). The methylmercury-to-total mercury ratio (Me-Hg/Hg-T) levels in scalp hair enabled interpretation of the results with respect to the degree of contamination by Hg, and the dietary habits of the sample donors of each fishing village under study. Furthermore, Se levels in scalp hair of the populations with relatively high Hg content were to be investigated for possible correlation with Me-Hg levels (''supplementary programme''). 5 refs, 2 figs, 9 tabs

    NASA’s Kepler Space Telescope was designed to determine the frequency of Earth-sized planets orbiting Sun-like stars, but these planets are on the very edge of the mission’s detection sensitivity. Accurately determining the occurrence rate of these planets will require automatically and accurately assessing the likelihood that individual candidates are indeed planets, even at low signal-to-noise ratios. We present a method for classifying potential planet signals using deep learning, a class of machine learning algorithms that have recently become state-of-the-art in a wide variety of tasks. We train a deep convolutional neural network to predict whether a given signal is a transiting exoplanet or a false positive caused by astrophysical or instrumental phenomena. Our model is highly effective at ranking individual candidates by the likelihood that they are indeed planets: 98.8% of the time it ranks plausible planet signals higher than false-positive signals in our test set. We apply our model to a new set of candidate signals that we identified in a search of known Kepler multi-planet systems. We statistically validate two new planets that are identified with high confidence by our model. One of these planets is part of a five-planet resonant chain around Kepler-80, with an orbital period closely matching the prediction by three-body Laplace relations. The other planet orbits Kepler-90, a star that was previously known to host seven transiting planets. Our discovery of an eighth planet brings Kepler-90 into a tie with our Sun as the star known to host the most planets.

    This study investigated the biological adaptation of loblolly pine following long-term seasonal exposure to elevated carbon dioxide (CO 2 ) partial pressures (pCO 2 ). Exposure to elevated atmospheric CO 2 (pCO 2 ) usually results in significant stimulation in light-saturated rates of photosynthetic CO 2 assimilation. Plants are protected against photoinhibition by biochemical processes known as photoprotection, including energy dissipation, which converts excess absorbed light energy into heat. This study was conducted in the eighth year of exposure to elevated pCO 2 at the Duke FACE site. The effect of elevated pCO 2 on electron transport and energy dissipation in the pine trees was examined by coupling the analyses of the capacity for photosynthetic oxygen (O 2 ) evolution, chlorophyll fluorescence emission and photosynthetic pigment composition with measurements of net photosynthetic CO 2 assimilation (Asat). During the summer growing season, Asat was 50 per cent higher in current-year needles and 24 per cent higher in year-old needles in elevated pCO 2 in comparison with needles of the same age cohort in ambient pCO 2 . Thus, older needles exhibited greater photosynthetic down-regulation than younger needles in elevated pCO 2 . In the winter, Asat was not significantly affected by growth pCO 2 . Asat was lower in winter than in summer. Growth at elevated pCO 2 had no significant effect on the capacity for photosynthetic oxygen evolution, photosystem 2 efficiencies, chlorophyll content or the size and conversion state of the xanthophyll cycle, regardless of season or needle age. There was no evidence that photosynthetic electron transport or photoprotective energy dissipation responded to compensate for the effects of elevated pCO 2 on Calvin cycle activity. 73 refs., 4 figs

  6. Fiscal Year 1994 progress in implementing Section 120 of the Comprehensive Environmental Rresponse, Compensation, and Liability Act. Eighth annual report to Congress

    1995-07-01

    Congress passed the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) (Public Law 96-510), commonly known as Superfund, in 1980. The Superfund Amendments and Reauthorization Act (SARA) (Public Law 99-499), which amended CERCLA in 1986, added Section 120 regarding the cleanup of contaminated sites at Federal facilities. Under Section 120(e)(5) of CERCLA, each department, agency, or instrumentality of the Federal government responsible for compliance with Section 120 must submit an annual report to Congress concerning its progress in implementing the requirements of Section 120. The report must include information on the progress in reaching Interagency Agreements (IAGs), conducting Remedial Investigation and Feasibility Studies (RI/FSs), and performing remedial actions. Federal agencies that own or operate facilities on the National Priorities List (NPL) are required to begin an RI/FS for these facilities within 6 months after being placed on the NPL. Remediation of these facilities is addressed in an IAG between the Federal agency, the U.S. Environmental Protection Agency (EPA), and in some instances the state within which the facility is located. This report, prepared by the U.S. Department of Energy's (DOE's) Office of Environmental Management, is being submitted to Congress in accordance with Section 120(e)(5) of CERCLA. It is DOE's Eighth Annual Report to Congress and provides information on DOE's progress in implementing CERCLA Section 120 in Fiscal Year 1994 (FY 94), i.e., from October 1, 1993, to September 30, 1994.

    Sargeant, Marcel Andre Almont

    Problem. Science education has long been a great concern in the United States, where less than one-third of the students perform at or above the proficient level. The purpose of this study was to investigate the status of the science program in a selected Union Conference of the Seventh-day Adventist school system. Specifically, this study investigated the perceptions of teachers and students regarding the extent to which the science program meets the criteria of the National Commission on Mathematics and Science Teaching for the 21st century and to what extent these criteria are related to academic performance as indicated by Iowa Test of Basic Skills (ITBS) science scores. Method. Two questionnaires designed by the researcher were used to get responses from 424 students in seventh and eighth grades and 68 teachers to see how this school system compares to the criteria of National Commission on Mathematics and Science Teaching for the 21 st century. Three classroom configurations were investigated in this study, namely: (a) multigrade, (b) two-grade, and (c) single-grade. Crosstabulation, one-way analysis of variance, Kruskal-Wallis test, and linear regression were used to analyze the four research questions of this study. Results. The single-grade classroom configuration received a better rating for the science criteria (p century. Conclusions. The differences in teaching practices explained the discrepancies in the three classroom configurations. Schools can therefore develop policies and strategies to improve the practices in the teaching and learning process in science education that were identified as being deficient by the criteria of National Commission on Mathematics and Science Teaching for the 21st century.

    Traditionally, women and minorities have not been fully represented in science and engineering. Numerous studies have attributed these differences to gaps in science achievement as measured by various standardized tests. Rather than describe mean group differences in science achievement across multiple cultures, this study focused on an in-depth item-level analysis across two countries: Spain and the United States. This study investigated eighth-grade gender differences on science items across the two countries. A secondary purpose of the study was to explore the nature of gender differences using the many-faceted Rasch Model as a way to estimate gender DIF. A secondary analysis of data from the Third International Mathematics and Science Study (TIMSS) was used to address three questions: 1) Does gender DIF in science achievement exist? 2) Is there a relationship between gender DIF and characteristics of the science items? 3) Do the relationships between item characteristics and gender DIF in science items replicate across countries. Participants included 7,087 eight grade students from the United States and 3,855 students from Spain who participated in TIMSS. The Facets program (Linacre and Wright, 1992) was used to estimate gender DIF. The results of the analysis indicate that the content of the item seemed to be related to gender DIF. The analysis also suggests that there is a relationship between gender DIF and item format. No pattern of gender DIF related to cognitive demand was found. The general pattern of gender DIF was similar across the two countries used in the analysis. The strength of item-level analysis as opposed to group mean difference analysis is that gender differences can be detected at the item level, even when no mean differences can be detected at the group level.

    Despite the attention that has been given to gender and science, boys continue to outperform girls in science achievement, particularly by the end of secondary school. Because it is unclear whether gender differences have narrowed over time (Leder, 1992; Willingham & Cole, 1997), it is important to continue a line of inquiry into the nature of gender differences, specifically at the international level. The purpose of this study was to investigate gender differences in science achievement across two countries: United States and Spain. A secondary purpose was to demonstrate an alternative method for exploring gender differences based on the many-faceted Rasch model (1980). A secondary analysis of the data from the Third International Mathematics and Science Study (TIMSS) was used to examine the relationship between gender DIF (differential item functioning) and item characteristics (item type, content, and performance expectation) across both countries. Nationally representative samples of eighth grade students in the United States and Spain who participated in TIMSS were analyzed to answer the research questions in this study. In both countries, girls showed an advantage over boys on life science items and most extended response items, whereas boys, by and large, had an advantage on earth science, physics, and chemistry items. However, even within areas that favored boys, such as physics, there were items that were differentially easier for girls. In general, patterns in gender differences were similar across both countries although there were a few differences between the countries on individual items. It was concluded that simply looking at mean differences does not provide an adequate understanding of the nature of gender differences in science achievement.

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

  15. A multi-level differential item functioning analysis of trends in international mathematics and science study: Potential sources of gender and minority difference among U.S. eighth graders' science achievement

    Science.gov (United States)

    Qian, Xiaoyu

    Science is an area where a large achievement gap has been observed between White and minority, and between male and female students. The science minority gap has continued as indicated by the National Assessment of Educational Progress and the Trends in International Mathematics and Science Studies (TIMSS). TIMSS also shows a gender gap favoring males emerging at the eighth grade. Both gaps continue to be wider in the number of doctoral degrees and full professorships awarded (NSF, 2008). The current study investigated both minority and gender achievement gaps in science utilizing a multi-level differential item functioning (DIF) methodology (Kamata, 2001) within fully Bayesian framework. All dichotomously coded items from TIMSS 2007 science assessment at eighth grade were analyzed. Both gender DIF and minority DIF were studied. Multi-level models were employed to identify DIF items and sources of DIF at both student and teacher levels. The study found that several student variables were potential sources of achievement gaps. It was also found that gender DIF favoring male students was more noticeable in the content areas of physics and earth science than biology and chemistry. In terms of item type, the majority of these gender DIF items were multiple choice than constructed response items. Female students also performed less well on items requiring visual-spatial ability. Minority students performed significantly worse on physics and earth science items as well. A higher percentage of minority DIF items in earth science and biology were constructed response than multiple choice items, indicating that literacy may be the cause of minority DIF. Three-level model results suggested that some teacher variables may be the cause of DIF variations from teacher to teacher. It is essential for both middle school science teachers and science educators to find instructional methods that work more effectively to improve science achievement of both female and minority students

    Socioeconomic, racial/ethnic, and gender inequalities in academic achievement have been widely reported in the US, but how these three axes of inequality intersect to determine academic and non-academic outcomes among school-aged children is not well understood. Using data from the US Early Childhood Longitudinal Study—Kindergarten (ECLS-K; N = 10,115), we apply an intersectionality approach to examine inequalities across eighth-grade outcomes at the intersection of six racial/ethnic and gender groups (Latino girls and boys, Black girls and boys, and White girls and boys) and four classes of socioeconomic advantage/disadvantage. Results of mixture models show large inequalities in socioemotional outcomes (internalizing behavior, locus of control, and self-concept) across classes of advantage/disadvantage. Within classes of advantage/disadvantage, racial/ethnic and gender inequalities are predominantly found in the most advantaged class, where Black boys and girls, and Latina girls, underperform White boys in academic assessments, but not in socioemotional outcomes. In these latter outcomes, Black boys and girls perform better than White boys. Latino boys show small differences as compared to White boys, mainly in science assessments. The contrasting outcomes between racial/ethnic and gender minorities in self-assessment and socioemotional outcomes, as compared to standardized assessments, highlight the detrimental effect that intersecting racial/ethnic and gender discrimination have in patterning academic outcomes that predict success in adult life. Interventions to eliminate achievement gaps cannot fully succeed as long as social stratification caused by gender and racial discrimination is not addressed. PMID:26505623

    Optimization problems arising in practice usually contain several random parameters. Hence, in order to obtain optimal solutions being robust with respect to random parameter variations, the mostly available statistical information about the random parameters should be considered already at the planning phase. The original problem with random parameters must be replaced by an appropriate deterministic substitute problem, and efficient numerical solution or approximation techniques have to be developed for those problems. This proceedings volume contains a selection of papers on modelling techniques, approximation methods, numerical solution procedures for stochastic optimization problems and applications to the reliability-based optimization of concrete technical or economic systems.

    Full Text Available 臺灣許多家長讓子女跨區到明星學校就讀,不過若依Coleman等人的論點,明星學校學生成績較好主要是因為它們收到高社經背景學生,而非教育品質較佳。研究者還沒看到有國內研究用校際間成績比較來檢證以上論點,研究者也就運用「臺東縣教育長期資料庫」2005年全縣國二學生普查資料檢證以上論點。研究結果顯示:臺東市某明星國中,在全縣標準化學業測驗中,成績居第二名,成績最高的是一所私校,此私校平均家庭收入比明星國中更高。在控制社經背景等出身背景變項後,各國中與明星國中的成績差距大幅縮減。明星國中學生社經背景較高,學生到校外補習班補學科比率最高,是該校成績較高的主要原因。 In Taiwan many parents send their children to prestigious schools across school districts. However, according to Coleman et al., higher student academic performance in prestigious schools is due to higher student socioeconomic background rather than better educational quality. As we had not seen comparative studies testing the above theory in Taiwan, we used the census data of eighth graders in Taitung Educational Panel Survey 2005 to understand this local phenomenon. It was showed that the average scores of students in the prestigious school ranked second, while students in one private school performed best. Those students in the private school had higher family income than students in the prestigious school. After controlling socioeconomic and other background variables, score gap between the prestigious school and others substantially decreased. Higher socioeconomic background and the highest cramming percentage accounted for the higher student academic performance in the prestigious school.

    扒窃型盗窃罪是《刑法修正案(八)》新增的盗窃罪独立定罪类型,也拓宽了扒窃行为入罪的评价路径。刑法上的扒窃是指“以非法占有为目的,秘密窃取他人随身携带的财物的行为”。但并不是所有的扒窃都可以构成扒窃型盗窃罪,只有符合“公共场合”、“从他人身上”以及“取得”等标准的扒窃行为才能构成扒窃型盗窃罪。扒窃型盗窃罪作为内涵最为丰富的盗窃罪定罪类型,其外延受到的限制最严格,所以当出现多种类型盗窃罪竞合时,理应首先认定行为是否构成扒窃型盗窃罪。%The pick-pocketing type Theft is a new type of independent theft in the "eighth Criminal Law Amendment ", which at the same time clear the way of incorporating pick-pocketing behavior into crime. Pick-pocketing in the criminal law referred to those behaviors which are for the purpose of illegal possession and by means of stealing others' property carried with in secret. However not all of pick-pocketing may constitute of pick-pocketing type theft, only those which are conducted in the "public places", from others' body and acquire may meet the definition. Pick-pocketing theft criminal type, who is the richest in connotation, has also the strictest restriction in its epitaxial. So when we meet multiple types of Theft competing, pick-pocketing type theft shall be considered in the first.

This research employed path analysis to examine such influence through questionnaire data from the Taitung Education Panel Survey conducted in 2005 on eighth graders and their parents. The results obtained are as follows. (1 The more abundant the refined cultural capital becomes, the more the positive teacher-student relationship and the more the positive as well as negative peer relationship will be. (2 The more the positive teacher-student relationship becomes, the better the academic performance of the students will be. (3 The more disadvantageous hobbies students have, the less the positive teacher-student relationship and the more the negative teacher-student as well as peer relationships will be, and these lead to their poorer academic performance. (4 The more the disadvantageous leisure students engaged in, the less the positive teacher-student relationship, the more the negative teacher-student relationship, and the more the positive peer relationship will be, and these also lead to their poorer academic performance.

    To maintain a sufficient number of qualified reading doctors for breast cancer mammography screening, we have held training courses across the nation. Grade-up examinations have been carried out for doctors who had failed to attain grade A or B at the training courses. We have evaluated the quality assurance of the examinations via questionnaires and reported the results on 7 previous occasions. In the present investigation, we reviewed all answers obtained from questionnaires at the previous 19 examinations, from the first one (November, 2000) until the last one (March, 2007). There were a total of 3,380 applicants, of whom 402 (11.9%) obtained grade A and 2,008 (59.4%) grade B. Thus a total 2,410 applicants (71.3%) obtained either A or B, and this rate was considerably superior to the 56% obtained in the first three examinations, although the former rate included the results of repeated applicants. These good results may have been due to an increase in the quality of the training courses and may have been affected by conducting the examinations not only in Nagoya but also in Tokyo and Osaka. In a period of about 10 months after April, 2004, the certification standard was increased and a system of certification reappraisal every 5 years was adopted. At that time, more than 75% of all applicants were A- or B-certified doctors at the 9th and 10th examinations, and the good results might have reflected the fact that many doctors tried hard to maintain a high reading ability. In February, 2005, the certification standard reverted to the previous one for various reasons, and the rate of A- or B-certified doctors decreased. In October, 2006, the examination changed from 100 questions concerning one-direction mammography to 50 one-direction questions and 50 two-direction questions, because of the adoption of two-direction mammography to age 40 years. Since it was widely recognized that the second reading at breast cancer screening should be done by A-certified doctors, many applicants tried to attain grade A after the 15th examination. As a result, the rate of A- or B-certified doctors increased. An every 5-year reappraisal system will again be adopted in 2007. We must recognize the importance of the original aim of screening to find curable cancers and further increase the quality of examination. (author)

    Laser ablation encompasses a wide range of delicate to extreme light interactions with matter that present considerably challenging problems for scientists to study and understand. At the same time, laser ablation also represents a basic process of significant commercial importance in laser material processing—defining a multi-billion dollar industry today. These topics were widely addressed at the 8th International Conference on Laser Ablation (COLA), held in Banff, Canada on 11-16 September 2005. The meeting took place amongst the majestic and natural beauty of the Canadian Rocky Mountains at The Banff Centre, where delegates enjoyed many inspiring presentations and discussions in a unique campus learning environment. The conference brought together world leading scientists, students and industry representatives to examine the basic science of laser ablation and improve our understanding of the many physical, chemical and/or biological processes driven by the laser. The multi-disciplinary research presented at the meeting underlies some of our most important trends at the forefront of science and technology today that are represented in the papers collected in this volume. Here you will find new processes that are producing novel types of nanostructures and nano-materials with unusual and promising properties. Laser processes are described for delicately manipulating living cells or modifying their internal structure with unprecedented degrees of control and precision. Learn about short-pulse lasers that are driving extreme physical processes on record-fast time scales and opening new directions from material processing applications. The conference papers further highlight forefront application areas in pulsed laser deposition, nanoscience, analytical methods, materials, and microprocessing applications. Laser ablation continues to grow and evolve, touching forefront areas in science and driving new technological trends in laser processing applications.

    Prevalence of congenital sensorineural hearing loss (SNHL) is approximately 1.5-6 in every 1,000 newborns. Dysfunction of the auditory nerve (auditory neuropathy) may be involved in up to 1%-10% of cases; hearing losses because of vestibulocochlear nerve (VCN) aplasia are less frequent. The objectives of this study were to describe clinical manifestations, hearing thresholds and aetiology of children with SNHL and VCN aplasia. We present 34 children (mean age 20 months) with auditory nerve malformation and profound HL taken from a sample of 385 children implanted in a 10-year period. We studied demographic characteristics, hearing, genetics, risk factors and associated malformations (Casselman's and Sennaroglu's classifications). Data were processed using a bivariate descriptive statistical analysis (P<.05). Of all the cases, 58.8% were bilateral (IIa/IIa and I/I were the most common). Of the unilateral cases, IIb was the most frequent. Auditory screening showed a sensitivity of 77.4%. A relationship among bilateral cases and systemic pathology was observed. We found a statistically significant difference when comparing hearing loss impairment and patients with different types of aplasia as defined by Casselman's classification. Computed tomography (CT) scan yielded a sensitivity of 46.3% and a specificity of 85.7%. However, magnetic resonance imaging (MRI) was the most sensitive imaging test. Ten percent of the children in a cochlear implant study had aplasia or hypoplasia of the auditory nerve. The degree of auditory loss was directly related to the different types of aplasia (Casselman's classification) Although CT scan and MRI are complementary, the MRI is the test of choice for detecting auditory nerve malformation.

    Full Text Available 本研究利用TIMSS 2003、2007與2011資料,分析臺灣八年級學生數學成就的城鎮都市間和鄉村都市間之差異。透過再中心化影響函數迴歸分析,發現城鎮都市間之成就差異從2007至2011年有顯著的擴大,此擴大是因都市學生成就提高所致。在2011年,都市低家庭教育資源後段學生成就進步,成就分布左側長尾縮短;都市高家庭教育資源中前段學生成就進步,成就分布向右拉長。在2011年,城鎮和鄉村學生平均落後都市學生0.45和0.57個標準差,約有一半是家庭教育資源城鄉差距所造成的。以TIMSS中級國際基準點作為基礎成就線,在2011年,落後人數比在都市、城鎮和鄉村分別是5%、13%和16%。家庭教育資源不足之學生,其落後人數比的城鄉差距較為嚴重。落後學生落後基礎成就線的幅度則無城鄉差異。 This study explored Taiwanese eighth graders’ mathematics achievement differences between town and urban areas and between rural and urban areas based on the data of TIMSS 2003 to 2011. Using recentered influence function regressions, the study has found that there were significant widening differences between the achievement of town students’ and that of urban students from 2007 to 2011 due to the improvement of urban students’ achievement. In 2011, the achievement of low ranking urban students with low home-education-resources have improved and the left tail of their distribution was shortened; the achievement of middle and high ranking urban students with high home-education-resources have improved and their distribution was stretched to the right. In 2011, comparing with urban students, town and rural students fall behind academically for 0.45 and 0.57 standard deviation on average, half of which was caused by the town-urban and rural-urban differences of homeeducation-resources. Using the intermediate international benchmark of TIMSS as the

  20. The Eighth Vibration. Asmara and Dek’emhare, Cities of Work, Cities of Leisure

    Directory of Open Access Journals (Sweden)

    Gian Luca Podestà

    2015-03-01

    Full Text Available The case of Asmara was emblematic. In 1934 Asmara had a population of about 3,500 Italians and 12,000 Africans. In 1939 Italians had risen to 48,000 whilst Africans were 36,000. In just five years the total population had increased fivefold, whilst the proportion between Italians and indigenous people had been reversed. This was an unprecedented phenomenon, determined by the economic importance of the city as a logistic base for the war. Asmara became the financial hub of the new Italian empire, where all major Italian companies had opened branches, as well as the seat of hundreds of new business enterprises born after the conquest of Ethiopia. Social life in Asmara was pulsating just like that of any other European town. During the day the heart of the city throbbed with business, both in the street markets and in the new Italian districts, where the offices of trading and industrial companies could be found. At night, social life moved to the ever expanding number of entertainment and leisure facilities. New dancehalls, restaurants and bars were being opened everywhere. The working men’s clubs and numerous sports and recreational societies, supported by local government and by the PNF, organised the colonists’ free time. In Eritrea, near the strategic hubs where companies and the army had located their logistic bases, new urban agglomerates rose from scratch, such as Dek’emhare and Nefasit, with plenty of restaurants and clubs, patronised by military personnel, workers and by the Italian nouveaux riches who, as Indro Montanelli denounced in his book “XX Battaglione Eritrea” (20th Eritrean Battalion lived a upper-class lifestyle, which went against the Fascist imperial ethos, thus betraying the ideal purpose of the African wars.

  7. Representation of acoustic signals in the eighth nerve of the Tokay gecko: I. Pure tones.

    Science.gov (United States)

    Sams-Dodd, F; Capranica, R R

    1994-06-01

    A systematic study of the encoding properties of 146 auditory nerve fibers in the Tokay gecko (Gekko gecko, L) was conducted with respect to pure tones and two-tone rate suppression. Our aim was a comprehensive understanding of the peripheral encoding of simple tonal stimuli and their representation by temporal synchronization and spike rate codes as a prelude to subsequent studies of more complex signals. Auditory nerve fibers in the Tokay gecko have asymmetrical, V-shaped excitatory tuning curves with best excitatory frequencies that range from 200-5100 Hz and thresholds between 4-35 dB SPL. A low-frequency excitatory 'tail' extends far into the low-frequency range and two-tone suppression is present only on the high frequency side of the tuning curve. The response properties to pure tones at different loci within a tuning curve can differ greatly, due to evident interactions between the representations of temporal, spectral and intensity stimulus features. For frequencies below 1250 Hz, pure tones are encoded by both temporal synchronization and spike rate codes, whereas above this frequency a fiber's ability to encode the waveform periodicity is lost and only a rate code predominates. These complimentary representations within a tuning curve raise fundamental issues which need to be addressed in interpreting how more complex, bioacoustic communication signals are represented in the peripheral and central auditory system. And since auditory nerve fibers in the Tokay gecko exhibit tonal sensitivity, selective frequency tuning, and iso-intensity and iso-frequency contours that seem comparable to similar measures in birds and mammals, these issues likely apply to most higher vertebrates in general. The simpler wiring diagram of the reptilian auditory system, coupled with the Tokay gecko's remarkable vocalizations, make this animal a good evolutionary model in which to experimentally explore the encoding of more complex sounds of communicative significance.

  8. MINIMIZING THE EIGHTH WASTE OF LEAN-ABSENTEEISM THROUGH SIX SIGMA METHODOLOGY

    C.S.Chethan Kumar

    2012-06-01

    Full Text Available The garment industries are labour intensive and are subjected to pollution in terms of dust and dyes. This is causing allergy and other huge amount health related issues. As employees are focused on stitching operations they tend to get injured when there is a lapse in attention. In India, garment industries are generally dominated by female workforce. There is a disparity in the male to female ratio. Most of the managers and supervisors are male and there is an increasing case of harassment towards the female workforce. Added to these conditions, the labour laws are no strict to protect the employees in terms of working conditions, job security and proper salaries. As a result there is an increase in employee absenteeism which is hurting the overall company growth and resulting in targets not being met. This research work is implemented in Apple garment industry located in South India.Absenteeism in garment industry is rampant and reaching alarming proportions. According to industry reports, if absenteeism is more than 10% , then the assembly line will be affected in terms of productivity.The majority of the garment industries in India are facing productivity problems due to employee absenteeism. The results after implementing the lean six sigma methodology in Apple garments is positive and a trend setter for other garment industries to follow. The existing absenteeism of 11.05% is a true reflection of the state of affairs in the garment sector. This research work has shown that absenteeism can be really controlled with the involvement of management.

    2002-10-01

    A corporate profile of Suncor Energy, a Canadian integrated energy company placing the emphasis on the development of the Athabasca oil sands in northern Alberta, is provided. A message from the president reiterates the company's commitment to improving both the environmental and economic performance through innovative policies and strategic management plans. A sustainable approach to climate change has meant an effort toward reducing the emissions of greenhouse gases and improving energy use. Suncor has lowered its greenhouse gas emission intensity by 11 per cent below 1990 levels in 2001. Total reductions of 12.9 million tonnes have been achieved during the period 1990-2001. The total absolute emissions are above 1990 levels, which can be explained by tremendous production growth at Suncor Energy. Suncor has developed a seven-point plan to address the issue of climate change as follows: manage its greenhouse gas emissions, develop renewable sources of energy, invest in environmental and economic research, use domestic and foreign offsets, collaborate with governments and other stakeholder groups on policy development, educate its employees and the public on ways to respond to the risk posed by climate change, and measure and report its progress from that perspective. The document is divided into sections. The first section provides an organization profile, and section two discusses senior management support. In section three, a review of base year methodology and quantification is provided, followed by projection in section four. Target setting is the topic of section five, while section six deals with measures to achieve targets. The results achieved are highlighted in section seven.

  5. Green Power Marketing in the United States: A Status Report (Eighth Edition)

    Energy Technology Data Exchange (ETDEWEB)

    Bird, L.; Swezey, B.

    2005-10-01

    Voluntary consumer decisions to purchase electricity supplied by renewable energy sources represent a powerful market support mechanism for renewable energy development. Beginning in the early 1990s, a small number of U.S. utilities began offering "green power" options to their customers. Since then, these products have become more prevalent, both from utilities and in states that have introduced competition into their retail electricity markets. Today, more than 50% of all U.S. consumers have an option to purchase some type of green power product from a retail electricity provider. This report provides an overview of green power marketing activity in the United States. The first section provides an overview of green power markets, consumer response, and recent industry trends. The second section provides brief descriptions of utility green pricing programs. The third section describes companies that actively market green power in competitive markets and those that market renewable energy certificates nationally or regionally. The final section provides information on a select number of large, nonresidential green power purchasers, including businesses, universities, and government agencies.

    International Nuclear Information System (INIS)

    Ito, Chikako; Sasaki, Hideo; Neriishi, Kazuo

    1992-01-01

    This is a report of the 7th survey of A-bomb survivor residents in Los Angeles, San Francisco, Seattle, Wailuku, and Honolulu conducted from June 11 through July 11, 1991. As of the end of July 1991, the number of A-bomb survivors registered in North America was 1,012, including 23 in Canada, which was increased by 94 compared with the end of July 1989. Of these A-bomb survivors, 963 (255 males and 708 females), excluding 49 deaths, were eligible for the present analysis. A-bomb survivors who had been exposed in Hiroshima accounted for 89.5%. The US nationality and the Japanese nationality with permanent US residency rights were seen in 61.5% and in 30.8%, respectively. They ranged in age from 45 to over 80 years of age, with a mean age of 61.2 years: those aged 55 to 64 years accounted for 52.5%. Those eligible for the Medicare program occupied one fourth of the total. Their residence was comprised of 28 states in the US and 3 provinces in Canada, with 60.7% living in the state of California, 19.4% in the state of Hawaii, and 5.8% in the state of Washington: overall, 67.8% were living on the west coast of the US. The number of A-bomb survivor's health handbook holders showed a 3.2-fold increase during the previous 8 years, with the acquisition rate being 55.5%. During the same period, the number of handbook holders among those with the US nationality showed a 3.4-fold increase, with the acquisition rate being 51.5%. Of a total of 963 eligible A-bomb survivors, 482 (50.1%) participated in the present examination, including 50 offspring (F 1 ). The most common disease requiring treatment and follow-up was hypertension (27.6%) followed by hyperlipidemia, liver disease, thyroid disease, heart disease, and diabetes mellitus in that order. The incidence of liver disease and thyroid disease was increased. (N.K.)

  1. The effect of outdoor environmental education on in-class behaviors of sixth, seventh and eighth grade students

    Science.gov (United States)

    Cumberbatch, Albert R.

    Does the natural environment enhance positive human behaviors, behaviors which meet societal expectations? If that is the case, at what level of our social development does exposure and involvement with nature become a prerequisite? This study sought to discover an answer to the first question through examination of a small public school sample. The second will have to await future study. Public schools, while making some token response to the rising environmental consciousness, have failed or completely ignored environmental education. This study focuses on using the natural environment as a classroom with an environmental education curriculum. The control was academic grades before the environmental education class. The independent variable was academic grades after environmental education. Comparisons of academic conduct grades between classes taken before and after environmental education were made. Three environmental education classes comprising ninety students were evaluated. The mean of all classes was calculated. Results indicate that there is a positive behavioral correlation between environment education and academic classes. However, there were many uncontrolled variables which necessitate further study. One example is the arbitrary standard among teachers for evaluating conduct grades. Conduct grades can also be subjective. In further studies, a standardized tool for evaluating conduct grades would be essential.

  2. 'Her choice of course': Negotiating legitimacy of 'choice' in abortion rights deliberations during the 'Repeal the Eighth' movement in Ireland.

    Discourses of 'choice' are routinely involved in sexual and reproductive rights' advocacy. In this article, we offer a discursive psychological examination of how 'choice' is oriented to, in online deliberations on the ongoing movement for abortion rights in Ireland. Comment posters treated 'choice' as involving outcomes of and motives for choosing, in negotiating legitimacy of women's rights to choose. These accompanied alternative versions of women, either as independent or as intimately bound up with pregnancy/motherhood, which were flexibly used in negotiation legitimacy of women's rights to 'choice' in abortion practices. Choice advocacy is then situated in particular discursive practices.

The committee report reviews and summarizes the two-year budget appropriation and the hearings before giving a section-by-section analysis. It notes that 46% is earmarked for waste management, and emphasizes the safety factors which have caused delays in construction and modifications in existing plants. 13 tables

  4. Proceedings of the Eighth Forum: Croatian Energy Day Energy markets and energy efficiency in transition economy countries'

    International Nuclear Information System (INIS)

    1999-01-01

    Energy efficiency is the sum total of various influential factors resulting from the technical, technological, economic, financial, legislative and organisational conditions that exist in each of the transition countries. It is not possible to achieve an efficient usage of energy as in the Western European countries unless the total efficiency of managing all other resources equals the same level. Therefore, in the preceding period only the most successful companies managed to take considerable steps as regards the enhancement of energy efficiency, i.e. companies present at the European market and equalling the criteria of the their competitors. The problem of energy efficiency can be explained with the help pf a number of factors influencing decision making of a company's management or a citizen. Those factors create a framework of events, i.w. an appropriate or an inappropriate atmosphere for the implementation of the measures to increase energy efficiency. Attitudes for and against certain activities develop in an atmosphere according to which individuals have to make decisions. Non-economic prices, non-existence of tariff systems or systems with socially influenced prices or tariffs, have a demotivating effect on all the activities in the field of energy efficiency. The existing legislation of the transition countries often enough neglects the problem of energy management, relating to either building planning and construction, or network systems, renewable sources or consumption standards at the market. The financial situation is also an important element when dealing with energy efficiency projects; high interest rates and major problems with the insurance of necessary financial funds impede their realisation. The support of expert and consulting institutions is a precondition for a successful choice of measures, and the educational system should take over its extremely important role at each of the education levels. Energy efficiency programmes cannot be launched without an active policy of governments and local communities, both in the legislative as in the financial sense. An adequate legislative regulation of this field, support funds, and fiscal measures are all included in the current practice of the developed countries. Experiences show that the speeding-up of the energy efficiency programme begins on the state level so that later on it could develop according to market rules. A new chapter in approaching energy efficiency began with the opening of the electric energy markets. It will be necessary to find new forms of support projects for the improvement of energy efficiency corresponding to the development of electric energy and natural gas markets

  5. Using interviews to understand the assignment mechanism in a nonexperimental study: the case of eighth grade algebra.

    Science.gov (United States)

    Rickles, Jordan H

    2011-10-01

    Many inquiries regarding the causal effects of policies or programs are based on research designs where the treatment assignment process is unknown, and thus valid inferences depend on tenuous assumptions about the assignment mechanism. This article draws attention to the importance of understanding the assignment mechanism in policy and program evaluation studies, and illustrates how information collected through interviews can develop a richer understanding of the assignment mechanism. Focusing on the issue of student assignment to algebra in 8th grade, I show how a preliminary data collection effort aimed at understanding the assignment mechanism is particularly beneficial in multisite observational studies in education. The findings, based on ten interviews and administrative data from a large school district, draw attention to the often ignored heterogeneity in the assignment mechanism across schools. These findings likely extend beyond the current research project in question to related educational policy issues such as ability grouping, tracking, differential course taking, and curricular intensity, as well as other social programs in which the assignment mechanism can differ across sites.

    Access to modern science and technology is essential for achieving all of the Millennium Development Goals. The IAEA gives priority to assisting developing countries in using nuclear technology in areas including health, food and agriculture, and water management. By making nuclear technology available through our technical cooperation programme, the IAEA makes a unique and lasting contribution to achiving the MDGs. Globally, health and nutrition make up the largest proportion of IAEA spending on technical cooperation. We have been working ever more closely with other UN specialized agencies, such as the World Health Organization and the Food and Agriculture Organization, in order to achieve more effective programme implementation. The Agency pays particular attention to training skilled personnel in the use of nuclear technology. We are also making increasing use of cost-effective e-learning tools. Cancer is reaching epidemic proportions in developing countries, but many countries lack the resources to deal with it. In fact, several dozen African nations have absolutely no radiotherapy facilities. Cancers which are increasingly treatable in developed countries are all too often fatal. The IAEA, together with the World Health Organisation, is playing its part by helping to make radiotherapy, medical physics, nuclear medicine, and imaging services available to developing countries. Our Programme of Action for Cancer Therapy (PACT) has been recognized by Member States as a flagship IAEA programme. But our efforts are just a drop in a vast ocean of human suffering. The world needs to mobilize its resources against cancer in a systematic way. This crisis must be addressed with a multipronged international effort to build awareness, develop diagnosis and treatment centres and train medical professionals. Tsetse flies infest vast areas of Africa. They transmit a parasitic disease which devastates livestock herds and spreads ''sleeping sickness'' among human beings. The IAEA is working closely with the African Union to help create tsetse- free zones, using the Sterile Insect Technique and other methods. The Sterile Insect Technique is essentially a form of contraception for tsetse flies. Male flies which are mass- produced in special facilities are sterilised using radiation. The sterile males are then released into affected areas, where they mate with wild females. These do not produce offspring. This technique can eventually eradicate entire populations of tsetse flies, as happened in Zanzibar in 1999. In recent years, significant progress has been made suppressing tsetse flies in Ethiopia and Senegal by using the Sterile Insect Technique and conventional methods. Together with 13 countries in the Sahel region of Africa, the IAEA is working to alleviate severe water shortages which have caused a humanitarian crisis. Underground aquifers that store fresh water span national borders in the region. The IAEA helps countries to measure and monitor these shared fresh water supplies suing nuclear isotopic techniques. This provides the data to enable policy-makers to develop a strategic plan for managing these vital resources. Responding to concerns among Member States about climate change, the new Ocean Acidification International Coordination Centre started work this year at the IAEA Environmental Laboratories in Monaco. This enhances our efforts to promote a comprehensive approach to the study, monitoring and protection of marine, coastal and terrestrial ecosystems. The annual IAEA Scientific Forum in September was entitled The Blue Planet: Nuclear Applications for a Sustainable Marine Environment. I informed the General Assembly a year ago about my plans to modernize the eight IAEA nuclear applications laboratories near Vienna. These do essential work in assisting with the transfer of nuclear science and technology to developing countries in areas such as human and animal health, food security and safety, agriculture, and environmental monitoring. My proposal has received strong support from Member States and we hope to complete the modernization in 2017. This will be a priority for the Agency over the next four years. Nuclear safety and security remain a matter of high priority for the IAEA. The Agency has continued to assist Japan in dealing with the aftermath of the Fukushima Daiichi accident. The recent leak of contaminated water was a clear reminder of the continuing impact of the accident. The IAEA has recommended that Japan establish an effective plan and mechanisms for the long-term management of contaminated water. The announcement by the Japanese Government of a basic policy for addressing this issue was an important step forward. An IAEA team will carry out a follow-up mission to Japan later this year. Steady progress has been made in implementation of the IAEA Action Plan on Nuclear Safety , which was agreed by our General Conference in 2011. The Agency has continued the series of post-Fukushima international expert meetings, with sessions on issues including decommissioning and remediation after a nuclear accident, and human and organizational factors in nuclear safety. Member States have recognized the central role of the IAEA in promoting international cooperation in nuclear safety. A comprehensive IAEA report on the Fukushima Daiichi accident will be finalized in 2014. In June this year, a Ministerial Conference on Nuclear Power in the 21st Century took place in St. Petersburg, Russia. One of the key messages was that, for many countries, nuclear power will play an important role in achieving energy security and sustainable development goals. The IAEA has a unique role in assisting governments, operators and regulators in understanding their international obligations and national responsibilities concerning nuclear power, as well as in adopting international standards and best practices.

    Chapman, Jarrett Michael

    Teachers are expected to improve their planning, instruction, and assessment as they progress through their career. An important component to teachers knowing what to modify in their teaching style is being able to solicit meaningful feedback from students. This mixed-methods study was conducted to provide teachers with a quantitative method to collect data about their teaching using the Constructivist Learning Environment Survey (CLES). Phase 1 allowed students to provide anonymous feedback to their teachers that the teachers could later reflect upon in conjunction with the students' other feedback. Using measures of central tendencies, it was determined that of the five categories of the CLES the area of student negotiation was statistically different from the other categories. While eight teachers had sufficient (n>10) student data to be invited to participate in Phase 2, only five of the teachers choose to participate in a semi-structured interview to further examine the potential differences between teacher and student perception of student negotiation with the curriculum, instruction and assessment that occurs in the classroom. Coding the interview transcripts led to three categories: 1) teaching style (with themes including curriculum, instruction, and assessment, and sub themes of teacher centered and student centered); 2) external pressures (with themes of standards , standardized tests, and socioeconomic conditions); 3) effectiveness of student negotiation (with themes of positive effect or no effect on motivation). The five teachers who participated in Phase 2 had varying levels of awareness and willingness to adjust their classroom curriculum, instruction, and assessment to include student negotiation. All but one teacher, however, saw the value in increasing student negotiation in the classroom and desired to continue to change their teaching to include more student negotiation.

    2003-01-01

    The past year has been a time of significant challenges and achievements for the IAEA. In the area of nuclear non-proliferation, the Agency has been at the centre of attention and has demonstrated its ability to perform objective and credible verification - but a number of difficult and unresolved situations continue to exist. In the area of nuclear safety and security, our work is making a difference and we see overall improvement, but much remains to be done. In the nuclear technology field, the Agency is contributing to sustainable development through its technical co-operation programme, with the benefits of nuclear applications increasingly recognized. And while nuclear power continues to hold great potential as an environmentally clean source of energy, it remains in a holding position due to a number of associated concerns. This statement reviews in some detail the following Agency's activities: Nuclear Technology and nuclear power; non-power nuclear application; nuclear safety and security; status of international conventions; safety standards; protection against nuclear and radiological terrorism; verification of nuclear non-proliferation; implementation of safeguards in Korea, Iran and Middle East; implementation of UN resolutions related to Iraq

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

  20. Perceptions of Eighth Graders Concerning the Aim, Effectiveness, and Scientific Basis of Pseudoscience: the Case of Crystal Healing

    2017-12-01

    Practices such as astrology or crystal healing can be defined as pseudoscience. Against pseudoscience, one of the major responsibilities of science education must be to develop science-literate individuals who are able to understand what science is, how science is undertaken, how scientific knowledge is constructed, and how it is justified, then they will be able to determine whether a claim is valid and be alert to practices which fall outside the realms of science, especially those in the area of pseudoscience. For this reason, the ability of recognizing flawed process and claims of pseudoscience is referred to one of the crucial parts of science literacy. The present study aimed to uncover middle school students' understanding of the inherent aim of pseudoscientists and pseudoscientific applications related to crystals and to reveal their judgments and justifications regarding the effectiveness and scientific basis of these applications. The present study was qualitative in nature. The results of the study showed that the students were very gullible about the aim, effectiveness, and scientific basis of pseudoscientific practices and in particular the use of crystals. Furthermore, similar to pseudoscientists, the students generally used weak reasoning to evaluate the presented claims and research designs about crystals and crystal healing.

  6. Occupational radiation exposure at commercial nuclear power reactors and other facilities 1995: Twenty-eighth annual report. Volume 17

    International Nuclear Information System (INIS)

    Thomas, M.L.

    1997-01-01

    This report summarizes the occupational exposure data that are maintained in the US Nuclear Regulatory Commission's (NRC) Radiation Exposure Information and Reporting System (REIRS). The bulk of the information contained in the report was compiled from the 1995 annual reports submitted by six of the seven categories of NRC licensees subject to the reporting requirements of 10 CFR 20.2206. Since there are no geologic repositories for high-level waste currently licensed, only six categories will be considered in this report. In 1995, the annual collective dose per reactor for light water reactor licensees (LWRs) was 199 person-cSv (person-rem). This is the same value that was reported for 1994. The annual collective dose per reactor for boiling water reactors (BWRs) was 256 person-cSv (person-rem) and, for pressurized water reactors (PWRs), it was 170 person-cSv (person-rem). Analyses of transient worker data indicate that 17,153 individuals completed work assignments at two or more licensees during the monitoring year. The dose distributions are adjusted each year to account for the duplicate reporting of transient workers by multiple licensees. In 1995, the average measurable dose calculated from reported data was 0.26 cSv (rem). The corrected dose distribution resulted in an average measurable dose of 0.32 cSv (rem)

    Tsai, Liang-Ting; Yang, Chih-Chien

    2015-05-01

    This study was conducted to understand the effect of student-, classroom-, and school-level factors on the science performance of 8th-grade Taiwanese students in the Trends in International Mathematics and Science Study (TIMSS) 2011 by using multilevel analysis. A total of 5,042 students from 153 classrooms of 150 schools participated in the TIMSS 2011 study, in which they were required to complete questionnaires. A 3-level multilevel analysis was used to assess the influence of factors at 3 levels on the science performance of 8th-grade Taiwanese students. The results showed that the provision of education resources at home, teachers' level of education, and school climate were the strongest predictor of science performance at the student, classroom, and school level, respectively. It was concluded that the science performance of 8th-grade Taiwanese students is driven largely by individual factors. Classroom-level factors accounted for a smaller proportion of the total variance in science performance than did school-level factors.

    Gowing, M.

    1977-01-01

    Some observations are made on the interdependence of scientists and politicians in the early atomic decision making in the United States and Britain. The motivation of scientists is also considered. In the pre-war period of discovery in atomic physics some scientists, individually or as groups showed their concern for the commercial possibilities of atomic power, while others did not; and some foresaw more quickly than others the military and political potential of their work. The paper deals particularly with three political-cum-moral questions: whether an atomic bomb should be made at all; whether the bomb when made should be used against Japan, and whether some attempt should be made, while the war was still on, to forestall a post-war nuclear arms race. The post-war work on the hydrogen bomb is also discussed. On all these topics the paper reports the historical development of events and the reactions of particular individuals and groups - scientists, politicians and others who were most involved in decision making.

  17. The Perceptions of STEM from Eighth-Grade African-American Girls in a High-Minority Middle School

    Science.gov (United States)

    Hare, LaChanda N.

    Even with the existence of STEM curriculum and STEM programs that target women and minorities, African-American females still lag behind other ethnic groups in STEM fields. Reasons for the underrepresentation of females in STEM fields can be traced back to the early years of schooling. The purpose of this study was to identify the factors that impact African-American females' perspectives of STEM subjects and STEM careers. An explanatory sequential mixed-methods approach was used for data collection with a survey, focus group, and interview. Forty male (N=12) and female (N=28) students from different ethnic groups were surveyed. The focus group and interview sessions consisted of 21 African-American females from two distinct groups: those enrolled in the school's STEM program (STEM) and those who were not enrolled in the STEM program (Non-STEM). The self-efficacy theory and social cognitive career theory served as the theoretical constructs guiding the data analysis. Multiple regression results showed that outcome expectation and personal disposition had the greatest influence on the females' interest in STEM content and STEM careers. Results from the qualitative portion of the study revealed that the learning environment and STEM self-efficacy had a significant impact on African-American females' interest in STEM.

    2004-01-01

    The Director General reviewed the Agency's activities in the past twelve months in his opening statement. The outlook for nuclear power is evolving, with increasing attention to its benefits as an environmentally clean source of electricity, but with concerns remaining related to waste disposal, safety and security. Nuclear applications related to human health, agriculture and other fields are increasingly contributing to global sustainable development initiatives, and the Agency has redoubled its efforts to support these initiatives by improving the efficiency and extending the reach of its technical cooperation programme. Global cooperation in matters of safety and security has resulted in good progress, but there is still much to be done. In the area of verification, the Agency's activities are at the centre of efforts to curb nuclear proliferation, and we have continued to prove our ability to conduct objective and credible safeguards but we still face a number of difficult and unresolved situations, and the international community has begun to focus on how to strengthen the nuclear non-proliferation regime

  18. Saving Mothers' Lives: Reviewing maternal deaths to make motherhood safer: 2006-2008. The Eighth Report of the Confidential Enquiries into Maternal Deaths in the United Kingdom.

    LENUS (Irish Health Repository)

    Cantwell, Roch

    2011-03-01

    In the triennium 2006-2008, 261 women in the UK died directly or indirectly related to pregnancy. The overall maternal mortality rate was 11.39 per 100,000 maternities. Direct deaths decreased from 6.24 per 100,000 maternities in 2003-2005 to 4.67 per 100,000 maternities in 2006–2008 (p = 0.02). This decline is predominantly due to the reduction in deaths from thromboembolism and, to a lesser extent, haemorrhage. For the first time there has been a reduction in the inequalities gap, with a significant decrease in maternal mortality rates among those living in the most deprived areas and those in the lowest socio-economic group. Despite a decline in the overall UK maternal mortality rate, there has been an increase in deaths related to genital tract sepsis, particularly from community acquired Group A streptococcal disease. The mortality rate related to sepsis increased from 0.85 deaths per 100,000 maternities in 2003-2005 to 1.13 deaths in 2006-2008, and sepsis is now the most common cause of Direct maternal death. Cardiac disease is the most common cause of Indirect death; the Indirect maternal mortality rate has not changed significantly since 2003-2005. This Confidential Enquiry identified substandard care in 70% of Direct deaths and 55% of Indirect deaths. Many of the identified avoidable factors remain the same as those identified in previous Enquiries. Recommendations for improving care have been developed and are highlighted in this report. Implementing the Top ten recommendations should be prioritised in order to ensure the overall UK maternal mortality rate continues to decline.

  6. A content analysis of sixth-grade, seventh-grade, and eighth-grade science textbooks with regard to the nature of science

    Science.gov (United States)

    Phillips, Marianne C.

    Science teachers rely heavily on their textbooks; for many, it is the only curriculum they use (Weiss, 1993). Therefore, it is important these materials convey an accurate conception of the nature of science. Science for All Americans (AAAS, 1990) and the National Science Education Standards (NRC, 1996) call for teaching students about the nature of science. Including the nature of science throughout science textbooks will produce scientifically literate citizens (Driver and others, 1993) with an improved ability to make informed decisions (McComas, 1998). Teaching the nature of science supports the successful learning of science content and process (Driver and others, 1996), and bridges the gap between the two cultures of practicing scientists and school science (Sorsby, 2000). Do middle school science textbooks provide a balanced presentation of the nature of science throughout their text? To determine the answer, this investigation used a content analysis technique to analyze a random sample from the introduction chapter and the rest of the textbook chapters from twelve middle school science textbooks for the four aspects of the nature of science (Chiappetta, Fillman, & Sethna, 2004). Scoring procedures were used to determine interrater agreement using both Cohen's kappa (kappa) and Krippendorff's alpha (alpha). Kappa values were determined to be fair to excellent beyond chance among the three coders. The resulting values for Krippendorff's alpha ranged from acceptable (alpha > .80) to unacceptable (alpha imbalance is providing students with a rudimentary and fragmented view of how science works, despite the fact that science impacts every aspect of life (McComas, 1998). Given the impact of textbooks on learning, it is recommended that teachers be informed of these shortcomings to enable them to supplement content where it is lacking.

    The mechanistic effects of mutagens and genotoxic agents has come a long way, with the availability of highly sensitive as well as high throughput techniques of genomics, proteomics and bioinformatics. Various types of cancer have facilitated the analysis of mutations and single nucleotide polymorphisms that can be associated with a particular type of cancer across the populations. Interestingly, though radiation remains an established carcinogen, its effects at very low doses and dose rates are still difficult to be ascribed for want of a molecular signature, notwithstanding the advancements in genomic analysis. The reflections of these new developments and unresolved issues in environmental mutagenesis and carcinogenesis are discussed in the conference. Papers relevant to INIS are indexed separately

    Davidson, Anne Burgess

    Did the Third International Mathematics and Science Study (TIMSS) ask science teachers the right questions about their use of instructional time? Part I of this 2-part study used the TIMSS database to answer the question: Do 8th grade science teachers in the U.S., Czech Republic, Hungary, Japan, and Korea differ significantly in their perceived use of instructional time? Using the instructional activities in the TIMSS teacher question "How did the lesson proceed?" the teacher-reported times were analyzed using a repeated measures multivariate analysis. Significant differences were found between teacher-reported times in the U.S. and the other 4 TIMSS countries, whose 8th grade students outperformed U.S. students on TIMSS achievement tests. Post-hoc analysis indicated that TIMSS U.S. 8th grade science teachers report spending more time on homework in class, on group activities, and on lab activities, but less time on topic development, than TIMSS teachers from some or all of the other countries. Part II of this study further examined the question "How did the lesson proceed?" by videotaping 6 classes of 8th grade science in Alabama and Virginia and comparing observer coding of the video to the teachers' recalled descriptions of the same class. The difference between observer and teacher responses using TIMSS categories was not significant; however, 43% of the total variance was explained by whether the teacher or the observer reported the times for the instructional activities. The teachers also responded to questions from the NSF Local Systemic Change Through Teacher Enhancement K--8 Teacher Questionnaire to describe the same class. The difference found between the teacher and the observer coding was not significant, but the amount of variance explained by the data source (observer or teacher) dropped to 33% when using NSF student activity categories and to 26% when using NSF teacher activity categories. The conclusion of this study was that questionnaires to survey science teachers about their instructional activities should include operational definitions, methods of classifying single activities into 2 or more instructional categories, and questions that are more accurate in describing quality science instructional activities.

  2. Harmonisation of European Migration Policies: The Failure of Immigration Control Policies in the Seventh and Eighth Decades of the 20th Century

    Directory of Open Access Journals (Sweden)

    Milan Mesić

    2003-12-01

    Full Text Available Until the middle of the 1970s, the migration policies of developed European countries were based on the assumption that controlling immigration was possible. Due to various reasons discussed in this article, such policies proved unsuccessful. The result was an increase in the total number of foreigners and a change in the composition of immigrant communities, i.e. the proportion of supported family members increased. During the 1980s there was increasing convergence in the migration policies of European immigration countries and traditional overseas emigration countries. Policies were more and more oriented towards preventing illegal migration flows, on regulating refugee flows and on balancing labour migration with family migration. The turning-point in the direction of “harmonising” West European migration policies was marked by the Schengen agreement (1985 on gradual elimination of border controls between the signing parties (France, Germany and the Benelux countries. Fear in the face of a possible invasion of Eastern Europeans after the collapse of socialism in 1989 was a further strong stimulus towards the harmonisation of migration policies in the developing EU. As opposed to migration control, the integration of immigrants has remained so far the prerogative of nation-states. The text further presents an overview of migration policy reforms in individual member states of the EU and of multilateral actions. The post-1989 migration regime in Europe has four major traits: 1 an extension of the agenda; 2 an accent on joint actions; 3 defensiveness; 4 confusion and an overload of issues. While on the one hand the EU continues to seek ways of protecting itself from undesired external migration, on the other hand the process of regional integration continues to “erase” its internal borders.

    The recent 2014 Evidence-Based Guideline for the Management of High Blood Pressure in Adults from the Eight Joint National Committee Panel may significantly impact the aging US population. We performed a cross-sectional analysis of black and white participants in ARIC who participated in the 5th study visit (2011–2013). Sitting blood pressure was calculated from the average of 3 successive readings taken after a 5-minute rest. Currently prescribed antihypertensive medications were recorded by reviewing medication containers brought to the visit. Blood pressure control was defined using both the 7th and 8th Joint National Committee thresholds. Of 6,088 participants (mean age 75.6 years [range 66–90], 58.4% female, 23.2% African American), 54.9% had either diabetes or chronic kidney disease. The prevalence of hypertension according to 7th Joint National Committee thresholds was 81.9%, and 62.8% of the entire sample were at blood pressure goal. Using the 8th Joint National Committee thresholds, 79.4% were at blood pressure goal (16.6% were reclassified as at goal). Reclassification was higher for individuals with diabetes or chronic kidney disease (20.6%) compared to individuals without either condition (11.6%). Use of antihypertensive medications in our cohort was high, with 75.0% prescribed at least one antihypertensive medication and 46.7% on 2 or more antihypertensive agents. In conclusion, in a US cohort of aging white and black individuals, approximately 1 in 6 individuals were reclassified as having blood pressure at goal by 8th Joint National Committee guidelines. Despite these less aggressive goals, over 20% remain uncontrolled by the new criteria. PMID:26150438

    In the 1991-1993 period, efforts were concentrated on establishing and validating the analytical methodology for determining total mercury (Hg-T) and methylmercury (MeHg) in human hair, and to identify any high risk populations in the study group. Two surveys were conducted during this period, which involved the collection of scalp hair samples that were prepared and analyzed for Hg-T, and also for MeHg in selected samples. The mean hair Hg-T concentration determined in the study group (1.81 ± 1.52 mg/kg, as dry weight) was significantly higher than the level obtained in the control group (0.42 ± 0.15 mg/kg). These results were characterized according to geographical location of the FVs, frequency of fish and seafood consumption and residence period in the same FV. Multiple comparison tests confirmed significant differences between the arithmetic means obtained in each FV and the control group. Five of the FVs with higher Hg-T concentrations in PW and NW were selected for further and more in-depth studies. A new survey, which is now in progress, is also described, which targets these five FVs and the associated control group. (author)

  14. Right-Hand Side Dependent Bounds for GMRES Applied to Ill-Posed Problems

    KAUST Repository

    Pestana, Jennifer

    2014-01-01

    © IFIP International Federation for Information Processing 2014. In this paper we apply simple GMRES bounds to the nearly singular systems that arise in ill-posed problems. Our bounds depend on the eigenvalues of the coefficient matrix, the right-hand side vector and the nonnormality of the system. The bounds show that GMRES residuals initially decrease, as residual components associated with large eigenvalues are reduced, after which semi-convergence can be expected because of the effects of small eigenvalues.

  20. Sin as an Ailment of Soul and Repentance as the Process of Its Healing. The Pastoral Concept of Penitentials as a Way of Dealing with Sin, Repentance, and Forgiveness in the Insular Church of the Sixth to the Eighth Centuries

    Directory of Open Access Journals (Sweden)

    Kursawa Wilhelm

    2017-05-01

    Full Text Available Although the advent of the Kingdom of God in Jesus contains as an intrinsic quality the opportunity for repentance (metanoia as often as required, the Church of the first five-hundred years shows serious difficulties with the opportunity of conversion after a relapse in sinning after baptism. The Church allowed only one chance of repentance. Requirement for the reconciliation were a public confession and the acceptance of severe penances, especially after committing the mortal sin of apostasy, fornication or murder. As severe as this paenitentia canonica appears, its entire conception especially in the eastern part of the Church, the Oriental Church, is a remedial one: sin represents an ailment of the soul, the one, who received the confession, is called upon to meet the confessing person as a spiritual physician or soul-friend. Penance does not mean punishment, but healing like a salutary remedy. Nevertheless, the lack of privacy led to the unwanted practice of postponing repentance and even baptism on the deathbed. An alternative procedure of repentance arose from the sixth century onwards in the Irish Church as well as the Continental Church under the influence of Irish missionaries and the South-West-British and later the English Church (Insular Church. In treatises about repentance, called penitentials, ecclesiastical authorities of the sixth to the eight centuries wrote down regulations, how to deal with the different capital sins and minor trespasses committed by monks, clerics and laypeople. Church-representatives like Finnian, Columbanus, the anonymous author of the Ambrosianum, Cummean and Theodore developed a new conception of repentance that protected privacy and guaranteed a discrete, an affordable as well as a predictable penance, the paenitentia privata. They not only connected to the therapeutic aspect of repentance in the Oriental Church by adopting basic ideas of Basil of Caesarea and John Cassian, they also established an astonishing network in using their mutual interrelations. Here the earlier penitentials served as source for the later ones. But it is remarkable that the authors in no way appeared as simple copyists, but also as creative revisers, who took regard of the pastoral necessities of the entrusted flock. They appeared as engaged in the goal to improve their ecclesiastical as well as their civil life-circumstances to make it possible that the penitents of the different ecclesiastical estates could perform their conversion and become reconciled in a dignified way. The aim of the authors was to enable the confessors to do the healing dialogue qualitatively in a high standard; quantity was not their goal. The penitents should feel themselves healed, not punished.

    Full Text Available El motivo del presente trabajo es relacionar el fin del dominio bizantino en el Sudeste de la península Ibérica con la conformación del territorio resultante por los visigodos, a tenor de la información escrita, pero, también, de algunos recientes descubrimientos arqueológicos como reductos fortificados en el entorno de Murcia. La hipótesis aquí defendida es que el contacto que significó la invasión bizantina condujo a los visigodos a crear una frontera militar que perduró hasta la llegada de los árabes en el año 713; que, en consecuencia, su existencia devino en el Pacto de Teodomiro y, por ello, una forma de fosilización de su vertebración administrativa.The purpose of this essay is to link the end of Byzantine rule in the southeast of the Iberian Peninsula with the transformation of the territory by the Visigoths according to written sources, as well as based on recent archaeological discoveries such as fortified bastions near the city of Murcia. The hypothesis presented here is that contact with the Byzantines during their invasion led the Visigoths to create a military frontier that lasted until the arrival of the Arabs in 713. Consequently, this reality brought forth the Pact of Tudmir and led to a relatively unmodified perpetuation of its administrative structure.

The results supported a three-factor solution reflecting ability beliefs, utility values, and intrinsic values. These factors and corresponding items all possessed strong reliability and validity. Among the three factors, ability beliefs exerted the strongest effect on mathematical achievements, explaining 36% of the variance of mathematical achievements. Gender invariance evidence was exhibited in the factor loadings, item intercepts, path coefficients, and factor variance/covariance. However, comparisons of latent factor means suggested that boys had significantly high mean scores regarding ability beliefs, utility values, and intrinsic values. Finally, suggestions for practical applications and future research are provided.

    The enforcement of federal safety regulations on the transport of radioactive and hazardous materials contained in the Hazardous Materials Transportation Act is the responsibility of the Department of Transportation, Nuclear Regulatory Commission, and the Environmental Protection Agency. Concern over the practice of charging less than 10% of the statutory maximum penalty and a poor record of collections raises questions about the diligence of enforcement agencies. Testimony by an Illinois state trooper revealed the extent of noncompliance, using the incident of the radioactive metal from Juarez, Mexico that was used to make table pedestals for illustration, and the state's response to the problem. Fourteen other witnesses from the enforcement agencies described procedures and problems. Additional material submitted for the record follows their testimony

    2005-01-15

    Australia is a net food exporting country, but also imports a considerable quantity of food from worldwide sources. Monitoring for safety of foods imported into Australia is the responsibility of the Australian Quarantine Inspection Service (AQIS). AQIS carries out the inspection and testing of food imports under the Imported Foods Inspection Program (IFIP). An advisory committee which contains food safety experts, conducts risk assessments on foods and advises AQIS on risk categorisation of the foods, and on the testing to be conducted. The rate of testing of individual food types is determined initially by the risk category, with high risk foods undergoing a higher rate of sampling than do lower risk foods. When a good safety history is established through the testing program for a high risk product from a particular producer, testing frequency is reduced. Sampling rates switch from sampling of all shipments to random sampling. The inspection and testing program is designed to comply with WTO requirements. (author)

  20. Computation of Value Functions in Nonlinear Differential Games with State Constraints

    KAUST Repository

    Botkin, Nikolai

    2013-01-01

    Finite-difference schemes for the computation of value functions of nonlinear differential games with non-terminal payoff functional and state constraints are proposed. The solution method is based on the fact that the value function is a generalized viscosity solution of the corresponding Hamilton-Jacobi-Bellman-Isaacs equation. Such a viscosity solution is defined as a function satisfying differential inequalities introduced by M. G. Crandall and P. L. Lions. The difference with the classical case is that these inequalities hold on an unknown in advance subset of the state space. The convergence rate of the numerical schemes is given. Numerical solution to a non-trivial three-dimensional example is presented. © 2013 IFIP International Federation for Information Processing.

    2012-01-01

    Proteins and their interactions are considered to play a significant role in many cellular processes. The identification of Protein-Protein interactions (PPIs) in human is an open research area. Many Databases, which contain information about experimentally and computationally detected human PPIs as well as their corresponding annotation data, have been developed. However, these databases contain many false positive interactions, are partial and only a few of them incorporate data from various sources. To overcome these limitations, we have developed HINT-KB (http://150.140.142.24:84/Default.aspx) which is a knowledge base that integrates data from various sources, provides a user-friendly interface for their retrieval, estimates a set of features of interest and computes a confidence score for every candidate protein interaction using a modern computational hybrid methodology. © 2012 IFIP International Federation for Information Processing.

  9. Energy-efficient two-hop LTE resource allocation in high speed trains with moving relays

    KAUST Repository

    Alsharoa, Ahmad M.

    2014-05-01

    High-speed railway system equipped with moving relay stations placed on the middle of the ceiling of each train wagon is investigated. The users inside the train are served in two hops via the 3GPP Long Term Evolution (LTE) technology. The objective of this work is to maximize the number of served users by respecting a specific quality-of-service constraint while minimizing the total power consumption of the eNodeB and the moving relays. We propose an efficient algorithm based on the Hungarian method to find the optimal resource allocation over the LTE resource blocks in order to serve the maximum number of users with the minimum power consumption. Moreover, we derive a closed-form expression for the power allocation problem. Our simulation results illustrate the performance of the proposed scheme and compare it with various previously developed algorithms as well as with the direct transmission scenario. © 2014 IFIP.

    Full Text Available The goal of this paper is to undertake a spatial and comparative analysis of the changes in the forest production in the Eighth Chilean Region based on a Geographic Information System (gis. The forest production is concentrated in the Seventh, Eighth, and Ninth Regions, which account for 76.8% of the planted area. The analysis will be based on spatialized information of the forest production for the Eighth region published in the Agricultural Census in 1997 and 2007. From 1997 to 2007 the forest area presented a strong expansion. This dynamic can bring many changes in the economy and society, and natural environments.

    Full Text Available In this study, the short stories titled “Nerede İnsan Varsa OradaUmut Vardır, Kedi Ağaca Çıktı and Hazır Olun Fırtına Geliyor” reviewedwithin the context of emotions, in the Turkish textbooks of the eighthgrade of primary education, were studied with a linguistic point of view.Determination of the main topic and sub-topics of the text; revealing ofthe deep structure of the text, that is its background as well as thevisible and understood part of the text, that is its surface structure allare possible by a textlinguistic approach. In this context, firstly, thegrammatical and lexical cohesive devices such as anaphora, cataphora,ellipse, reiteration, junctions and collocation defined as grammaticalcohesion and lexical cohesion which constitute the microstructure ofthe text were examined afterwards, the subject was explained withsamples from the stories. In terms of the macrostructure of the text, theshort stories named “Hazır Olun Fırtına Geliyor” type of moment,“Nerede İnsan Varsa Orada Umut Vardır” type of trial and “Kedi AğacaÇıktı” type of humor were commented and it was tried to reach thesemantic macrostructure by virtue of collocation and cohesion formedthrough the words in the same concept area. The microstructure stonesforming the macrostructure of the text make the text meaningful byrealizing the pattern of the text with its other elements. In the textanalysis, it is tried to reach from microstructure to macrostructure fromthis to the categories of superstructures. The aim of textlinguistics is toreveal the structures of the texts, that is the forms of grammatical andcontextual fiction and to demonstrate it with the practical samples. Thisstudy represents the reality of texts is not the series of the sentencesbut a coherent and continuous whole in terms of structure and theme,by means of short stories. Bu araştırmada, İlköğretim 8. Sınıf Türkçe Ders Kitabı‟nın „Duygular‟ temasında yer alan „Nerede İnsan Varsa Orada Umut Vardır‟, „Kedi Ağaca Çıktı‟ ve „Hazır Olun Fırtına Geliyor‟ adlı kısa öyküler metindilbilimsel bir bakış açısıyla incelenmeye çalışılmıştır. Metnin temel konusu ve alt konularının belirlenmesi; metnin görünen, anlaşılan kısmının, yani yüzey yapısının yanında, metnin derin yapısının, yani metnin arka planının ortaya konması ancak metindilbilimsel bir yaklaşımla mümkün olabilmektedir. Bu bağlamda, öncelikle metnin küçük ölçekli yapısını oluşturan artgönderim, öngönderim, eksiltili yapı, yineleme, bağıntı öğeleri, eşdizimsel örüntü gibi dilbilgisel ve sözcüksel bağlaşıklık düzenekleri ele alınmış, daha sonra öykülerden alınan örneklerle konuya açıklık kazandırılmıştır. Metnin büyük ölçekli yapısı bağlamında, anı türündeki „Hazır Olun Fırtına Geliyor‟, deneme türündeki „Nerede İnsan Varsa Orada Umut Vardır‟ ve mizah türündeki „Kedi Ağaca Çıktı‟ adlı metinler yorumlanmış, aynı kavram alanından sözcüklerin oluşturduğu örüntü ve bağlaşıklık düzeneklerine dayanarak anlamsal büyük yapıya ulaşılmaya çalışılmıştır. Metnin büyük ölçekli yapısını oluşturan küçük ölçekli yapı taşları, metnin diğer ögeleriyle metin örüntüsünü gerçekleştirerek metni anlamlı kılmaktadır. Metin çözümlemelerinde, küçük ölçekli yapıdan büyük ölçekli yapıya, büyük ölçekli yapıdan da üst yapı kategorilerine ulaşılmaya çalışılmalıdır. Metindilbilimin amacı, metinlerin yapılarını, yani dilbilgisel ve içeriksel kurgulanma biçimlerini ve bildirişimsel işlevlerini ortaya çıkarmak ve uygulamalı örneklerle göstermektir. Çalışma, metnin sıralı tümceler dizisi değil, izlek ve yapı yönünden tutarlı ve sürekli bir bütün olduğu gerçeğini öyküler üzerinden bize sunmaktadır.

  17. Creep Rupture Life Prediction Based on Analysis of Large Creep Deformation

    Directory of Open Access Journals (Sweden)

    YE Wenming

    2016-08-01

    Full Text Available A creep rupture life prediction method for high temperature component was proposed. The method was based on a true stress-strain elastoplastic creep constitutive model and the large deformation finite element analysis method. This method firstly used the high-temperature tensile stress-strain curve expressed by true stress and strain and the creep curve to build materials' elastoplastic and creep constitutive model respectively, then used the large deformation finite element method to calculate the deformation response of high temperature component under a given load curve, finally the creep rupture life was determined according to the change trend of the responsive curve.The method was verified by durable test of TC11 titanium alloy notched specimens under 500 ℃, and was compared with the three creep rupture life prediction methods based on the small deformation analysis. Results show that the proposed method can accurately predict the high temperature creep response and long-term life of TC11 notched specimens, and the accuracy is better than that of the methods based on the average effective stress of notch ligament, the bone point stress and the fracture strain of the key point, which are all based on small deformation finite element analysis.

  18. Life prediction for high temperature low cycle fatigue of two kinds of titanium alloys based on exponential function

    Science.gov (United States)

    Mu, G. Y.; Mi, X. Z.; Wang, F.

    2018-01-01

    The high temperature low cycle fatigue tests of TC4 titanium alloy and TC11 titanium alloy are carried out under strain controlled. The relationships between cyclic stress-life and strain-life are analyzed. The high temperature low cycle fatigue life prediction model of two kinds of titanium alloys is established by using Manson-Coffin method. The relationship between failure inverse number and plastic strain range presents nonlinear in the double logarithmic coordinates. Manson-Coffin method assumes that they have linear relation. Therefore, there is bound to be a certain prediction error by using the Manson-Coffin method. In order to solve this problem, a new method based on exponential function is proposed. The results show that the fatigue life of the two kinds of titanium alloys can be predicted accurately and effectively by using these two methods. Prediction accuracy is within ±1.83 times scatter zone. The life prediction capability of new methods based on exponential function proves more effective and accurate than Manson-Coffin method for two kinds of titanium alloys. The new method based on exponential function can give better fatigue life prediction results with the smaller standard deviation and scatter zone than Manson-Coffin method. The life prediction results of two methods for TC4 titanium alloy prove better than TC11 titanium alloy.

  19. Preparation and Properties of Ti-TiN-Zr-ZrN Multilayer Films on Titanium Alloy Surface

    Directory of Open Access Journals (Sweden)

    LIN Song-sheng

    2017-06-01

    Full Text Available 24 cycles Ti-TiN-Zr-ZrN soft-hard alternating multilayer film was deposited on TC11 titanium alloy by vacuum cathodic arc deposition method. The structure and performance of the multilayer film, especially wear and sand erosion resistance were investigated by various analytical methods including pin on disc wear tester, sand erosion tester, 3D surface topography instrument, scanning electron microscopy (SEM, X-ray diffraction(XRD, micro-hardness tester and scratch adhesion tester. The results indicate that the Vickers-hardness of the multilayer film with thickness of 5.8μm can reach up to 28.10GPa. The adhesive strength of these coatings can be as high as 56N. Wear rate of the multilayer coated alloy is one order of magnitude smaller than bare one, which decreased from 7.06×10-13 m3·N-1·m-1 to 3.03×10-14m3·N-1·m-1. Multilayer films can play the role in hindering the extension of cracks, and thus sand erosion properties of the TC11 titanium alloy substrates are improved.

  20. Sequential decoders for large MIMO systems

    KAUST Repository

    Ali, Konpal S.

    2014-05-01

    Due to their ability to provide high data rates, multiple-input multiple-output (MIMO) systems have become increasingly popular. Decoding of these systems with acceptable error performance is computationally very demanding. In this paper, we employ the Sequential Decoder using the Fano Algorithm for large MIMO systems. A parameter called the bias is varied to attain different performance-complexity trade-offs. Low values of the bias result in excellent performance but at the expense of high complexity and vice versa for higher bias values. Numerical results are done that show moderate bias values result in a decent performance-complexity trade-off. We also attempt to bound the error by bounding the bias, using the minimum distance of a lattice. The variations in complexity with SNR have an interesting trend that shows room for considerable improvement. Our work is compared against linear decoders (LDs) aided with Element-based Lattice Reduction (ELR) and Complex Lenstra-Lenstra-Lovasz (CLLL) reduction. © 2014 IFIP.
