    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.

    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.

    The flow behavior and dynamic globularization of TC11 titanium alloy during subtransus deformation are investigated through hot compression tests. A constitutive model is established based on physical-based hardening model and phenomenological softening model. And based on the recrystallization mechanisms of globularization, the Avrami type kinetics model is established for prediction of globularization fraction and globularized grain size under large strain subtransus deformation of TC11 alloy. As the preliminary application of the previous results, the cogging process of large size TC11 alloy billet is simulated. Based on subroutine development of the DEFORM software, the coupled simulation of one fire cogging process is developed. It shows that the predicted results are in good agreement with the experimental results in forging load and microstructure characteristic, which validates the reliability of the developed FEM subroutine models.

The results indicate that the deposited TC11 titanium alloys and the interfacial re-melted layer present a typical Widmanstatten structure and the heat affected zone (HAZ) within the substrate changes gradually from Widmanstatten to duplex microstructure. Compared to the interface transition zone and the substrate, the as-deposited TC11 alloy possesses higher tensile strength and lower ductility. The damaged impeller blades are repaired by laser melting deposition in a point-by-point way. After machining and checking, the repaired impeller passes the over speed test and comes into real use.

    In the present investigation, the correlation of composition-processing-property for TC11 titanium alloy was established using principal component analysis (PCA) and artificial neural network (ANN) based on the experimental datasets obtained from the forging experiments. During the PCA step, the feature vector is extracted by calculating the eigenvalue of correlation coefficient matrix for training dataset, and the dimension of input variables is reduced from 11 to 6 features. Thus, PCA offers an efficient method to characterize the data with a high degree of dimensionality reduction. During the ANN step, the principal components were chosen as the input parameters and the mechanical properties as the output parameters, including the ultimate tensile strength ( \\upsigma_{{b}} ), yield strength ( \\upsigma_{0.2} ), elongation ( \\updelta ), and reduction of area (φ). The training of ANN model was conducted using back-propagation learning algorithm. The results clearly present ideal agreement between the predicted value of PCA-ANN model and experimental value, indicating that the established model is a powerful tool to construct the correlation of composition-processing-property for TC11 titanium alloy. More importantly, the integrated method of PCA and ANN is also able to be utilized as the mechanical property prediction for the other alloys.

    The Ti-24Al-15Nb-1.5Mo alloy, in the as-forged and heat-treated states, was joined to the as-forged TC11 titanium alloy by electron beam welding with the heat inputs of 135 and 150 kJ/m. Then the microstructure and property of the Ti-24Al-15Nb-1.5Mo/TC11 welding interface were investigated. The results show that the phase constitution of the weld is not related to the heat input, and is mainly composed of α' phase. Moreover, the intermetallic phases of Ti_2AlNb, MoNb, Nb_3Al, and TiAl_3 are formed in the weld zone. Therefore, the microhardness value of the weld zone is higher than that of the other portions in the same sample. The profile of the weld is asymmetrically funnel-like. The grain sizes of the weld and its heat-affected zones are increased with increasing heat input. There is an obvious difference in the element content of the welding interface; only the alloying elements in the fusion zone reach a new balance during solidification.

    1999-03-01

    In recent years the distributed systems community has witnessed a growth in the number of conferences, leading to difficulties in tracking the literature and a consequent loss of awareness of work done by others in this important research domain. In an attempt to synthesize many of the smaller workshops and conferences in the field, and to bring together research communities which were becoming fragmented, IFIP staged Middleware'98: The IFIP International Conference on Distributed Systems Platforms and Open Distributed Processing. The conference was widely publicized and attracted over 150 technical submissions including 135 full paper submissions. The final programme consisted of 28 papers, giving an acceptance ratio of a little over one in five. More crucially, the programme accurately reflected the state of the art in middleware research, addressing issues such as ORB architectures, engineering of large-scale systems and multimedia. The traditional role of middleware as a point of integration and service provision was clearly intact, but the programme stressed the importance of emerging `must-have' features such as support for extensibility, mobility and quality of service. The Middleware'98 conference was held in the Lake District, UK in September 1998. Over 160 delegates made the journey to one of the UK's most beautiful regions and contributed to a lively series of presentations and debates. A permanent record of the conference, including transcripts of the panel discussions which took place, is available at: http://www.comp.lancs.ac.uk/computing/middleware98/ Based on their original reviews and the reactions of delegates to the ensuing presentations we have selected six papers from the conference for publication in this special issue of Distributed Systems Engineering. The first paper, entitled `Jonathan: an open distributed processing environment in Java', by Dumant et al describes a minimal, modular ORB framework which can be used for supporting real

The input parameters of this model were 9 kinds of elements, including Al, Mo, Zr, Si, Fe, C, O, N and H. The mechanical properties were used as output parameters, including ultimate tensile strength, yield strength, elongation and reduction of area. The prediction capability of the established model was tested by the unseen data sample. Additionally, the effect of chemical elements (Al、 MO、Zr and C) on the mechanical property was studied using the present model. It is found that the relative errors between predicted and experimental values all within 10%, indicating that the neural network model possesses excellent prediction capability. With the help of the trained ANN model, the nonlinear relationship of chemical elements and mechanical property can also be clearly presented.

    为提高钛合金表面耐磨性能,运用电火花沉积技术在TC11钛合金表面原位反应沉积TiN强化层,研究N2流量对强化层显微组织和摩擦学性能的影响。结果表明:当N2流量过小时,强化层厚度较薄,主要由Ti2N、α-Ti、TiO和TiN等相组成,电火花快速放电导致基体表面产生的熔池急速冷凝,使得亚稳态Ti2N相保留在强化层中;当N2流量过大时,强化层微裂纹和孔洞等缺陷较多;而当N2流量适中时,强化层主要由TiN等物相组成,且致密均匀(50~55µm),平均显微硬度达HV0.21165.2,是TC11钛合金基体的3.4倍。当N2流量适中时,TiN强化层的耐磨性能最好,此时其磨损质量为0.4 mg,是TC11基体的2/9,其主要磨损机理为微观切削磨损和多次塑变磨损。%In order to improve the tribological properties of titanium alloys, the in-situ TiN coatings were prepared by electrospark deposition (ESD) on the surface of TC11 titanium alloy. The effects of nitrogen flux on the microstructure and tribological properties of TiN coatings were investigated. The results show that the coating is relative thin when the nitrogen flux is small and mainly consists of Ti2N,α-Ti, TiO and TiN phases, and the metastable phase of Ti2N is developed due to the rapid solidification of ESD. While in excessive nitrogen flux condition, many micro-cracks and holes might be generated in the coating. In moderate nitrogen flux, the coating is mainly composed of TiN phase, and is dense and uniform (50−55 µm). The average hardness is HV0.2 1165.2, which is 3.4 times that of the TC11 substrate. The TiN coatings prepared in moderate nitrogen flux perform the best wear resistance. The wear loss of the coating is 0.4 mg, which is 2/9 that of the TC11 substrate. The main wear mechanisms of the coatings are micro-cutting wear accompanied by multi-plastic deformation wear.

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

    2007-01-01

    The contribution to the eighth-order anomalous magnetic moment (g-2) of the electron from a set of diagrams without closed lepton loops is recalculated using a new FORTRAN code generated by an automatic code generator. Comparing the contributions of individual diagrams of old and new calculations, we found an inconsistency in the old treatment of infrared subtraction terms in two diagrams. Correcting this error leads to the revised value -1.9144 (35) (alpha/pi)^4 for the eighth-order term. This theoretical change induces the shift of the inverse of the fine structure constant by -6.41180(73)x10^{-7}.

    The eighth generation of the International Geomagnetic Reference Field (IGRF) was adopted in 1999 by the International Association of Geomagnetism and Aeronomy (IAGA) Division V, Working Group 8. This differs from the previous generation by the addition of the IGRF 2000 which comprises a main-field model for the epoch 2000.0 and a predictive secular-variation model for 2000.0-2005.0. This paper lists the IGRF coefficients and includes contour maps computed using IGRF 2000.

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

    Science.gov (United States)

    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.

    2010-01-01

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

    With long-term war experience abroad, combined with the actual situation of health work in China, Bethune put forward a series of strategy and theory used in battlefield conditions of rescuing the wounded in China, such as "fire rescue, early debridement", "emergency blood transfusion in battlefield" and "the crowd blood bank", which effectively improved the rate of saving the battlefield wounded rate in the actual war. Combining with his own practice, he invented a variety of surgical instruments and equipment, such as "lugou bridge" medicine cabinet, "Bipp ointment", which have been widely used in the battlefield. He paid more attention to the construction of battlefield hospital, proposed the establishment of "Model Hospital" and "Special Surgery Hospital" in the rear of Anti-Japanese War, founded the health school, and wrote many battlefield medical books and skills data. Bethune trained a large number of medical personnel for the war front, laid the foundation for the field surgery education of the Eighth Route Army.

    There is controversy over the optimal timing of microtia reconstruction. The eighth costal cartilage, which is used to shape the helix framework, can be one of the key factors determining surgical timing of microtia reconstruction. Nevertheless, it is difficult to predict the length of the eighth costal cartilage preoperatively. The aim of the present study was to suggest clinical predictors of the length of the eighth cartilage by assessing the correlation between the actual length of the eighth cartilage and preoperative measurements of the cartilage length using three-dimensional rib-cage computed tomography (3D rib-cage CT). A retrospective analysis was performed on a total of 97 patients who underwent preoperative 3D rib-cage CT and auricular reconstruction using a rib cartilage graft between January 2010 and February 2013. The length of the eighth costal cartilage on 3D rib-cage CT was measured preoperatively, and the length of the harvested eighth rib cartilage was measured intraoperatively. We analyzed the association between the preoperative and intraoperative measured length of the eighth rib, with patient age, height, weight, and body mass index. Preoperative measurement using 3D rib-cage CT showed a high correlation with actual cartilage length. Height and weight correlated more strongly with length than with age. This study describes the usefulness of 3D rib-cage CT for preoperative measurement of the length of the eighth costal cartilage. The measurement of the eighth rib cartilage on 3D rib-cage CT could be a useful aid for reconstructive surgeons in planning microtia reconstruction.

    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.

    The prognostic value of the proposed eighth edition of the American Joint Committee on Cancer (AJCC) tumor, node, and metastasis (TNM) classification is currently unclear. The aim of the study was to evaluate the prognostic value of the eighth edition of the AJCC TNM classification. We retrospectively assessed 3176 patients with differentiated thyroid carcinoma (DTC) who underwent thyroidectomy at a tertiary Korean hospital from 1996 to 2005. Cancer-specific survival (CSS) was analyzed using the Kaplan-Meier method and compared using the log-rank test. Performance of the eighth edition TNM with respect to prediction of CSS was assessed against the current seventh edition. Upon reclassification according to the eighth edition, 37.6% of patients were down-staged. The proportions of stage I and II tumors increased from 61.9% to 81.1% and from 1.7% to 16.0%, respectively, whereas those of stage III and IVB (formerly IVC in the seventh edition) decreased from 27.6% to 2.3% and 0.8% to 0.5%, respectively. The proportions of variance explained (PVEs) for the ability of the eighth and the seventh edition to predict CSS were 3.9% and 2.9%, respectively. The C-index values were 0.765 (95% confidence interval 0.764-0.766) for the eighth edition and 0.736 (0.735-0.737) for the seventh edition. Our results demonstrate that the eighth edition TNM more accurately predicts CSS for patients with DTC than does the seventh edition. Copyright © 2017 Elsevier Ltd. All rights reserved.

    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%.

    The aim of this study was to validate stage groupings in the eighth edition of the TNM classification in an independent Chinese cohort. We retrospectively analyzed a total of 3599 patients with pathological stage IA to IIIA (seventh edition of the TNM) NSCLC who underwent surgical treatment in two surgical centers in the People's Republic of China between 2005 and 2012. All patients were reclassified according to the eighth edition of the TNM classification. Survival was compared between adjacent stage groupings by using a log-rank test and a Cox regression model. R(2) was calculated to evaluate the discrimination of the two TNM stage classifications. The median follow-up time was 48.7 months. According to the eighth edition of the TNM classification, the overall survival (OS) of adjacent stage groupings showed significant differences except for IA3 vs. IB. The eighth edition of the TNM classification yielded a slightly higher R(2) than the seventh edition (0.172 vs. 0.162). This study provided an external validation of the stage groupings in the eighth edition of the TNM classification for lung cancer among surgically treated Chinese patients with NSCLC.

    Hamre, B K; Pianta, R C

    2001-01-01

    This study followed a sample of 179 children from kindergarten through eighth grade to examine the extent to which kindergarten teachers' perceptions of their relationships with students predict a range of school outcomes. Kindergarten teachers rated children's behavior and the quality of the teacher-child relationship. Follow-up data from first through eighth grade were organized by epoch and included academic grades, standardized test scores, work-habit ratings, and discipline records. Relational Negativity in kindergarten, marked by conflict and dependency, was related to academic and behavioral outcomes through eighth grade, particularly for children with high levels of behavior problems in kindergarten and for boys generally. These associations remained significant after controlling for gender, ethnicity, cognitive ability, and behavior ratings. The results have implications for theories of the determinants of school success, the role of adult-child relationships in development, and a range of early intervention and prevention efforts.

  2. 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

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

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

    2016-09-01

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

    2016-09-01

    Costochondral grafts have long been used in maxillofacial reconstruction, but have been little used in trauma and orthopedic cases. This surgical technique requires that a graft be harvested from the thorax in the area of the eighth rib. Pleuropulmonary complications are very rare. Although the harvesting technique is simple, it needs to be demystified. This study was performed to define anatomical relationships in the eighth costochondral junction and identify topographical and anatomical landmarks that will make it easier to harvest this structure. This was a two-part study. First, an anatomical study was carried out on human cadaver thoraxes to define topographical landmarks and study the anatomical surroundings of the eighth costochondral junction. Second, an imaging study was performed using a database of existing patient computed tomography (CT) scans of the chest and abdomen to confirm the topographical landmarks defined in the first part of the study. The spine was used as a reference for both studies. The location of the eighth costochondral junction was defined relative to the spinal processes along with its location on the lower rib cage hemiperimeter in the transverse plane starting at the corresponding spinous process. The eighth costochondral junction was in line with the spinal process of the twelfth thoracic vertebra in the vast majority of cases and located at two-thirds of the lower rib cage hemiperimeter from the posterior median sulcus, regardless of the patient's chest shape, age and gender. This junction was always located under a single muscle (external oblique) and protected by a thick perichondrium layer, which separates it from the intercostal pedicles, endothoracic fascia and parietal pleura. This two-part study has identified reliable landmarks for harvesting of an osteochondral graft at the eighth costochondral junction and, by describing its anatomical surroundings, helps take the mystery out of its harvesting. These landmarks were

    2010-12-01

    We present a derivation of the recently proposed eighth-order phase-field crystal model [A. Jaatinen , Phys. Rev. E 80, 031602 (2009)10.1103/PhysRevE.80.031602] for the crystallization of a solid from an undercooled melt. The model is used to study the planar growth of a two-dimensional hexagonal crystal, and the results are compared against similar results from dynamical density functional theory of Marconi and Tarazona, as well as other phase-field crystal models. We find that among the phase-field crystal models studied, the eighth-order fitting scheme gives results in good agreement with the density functional theory for both static and dynamic properties, suggesting it is an accurate and computationally efficient approximation to the density functional theory.

  3. Mathematics achievement of Serbian eighth grade students and characteristics of mathematics curriculum

    Directory of Open Access Journals (Sweden)

    Antonijević Radovan M.

    2006-01-01

    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.

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

    Science.gov (United States)

    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

  5. KENNEDY, KENNEDY, AND THE EIGHTH AMENDMENT: “STILL IN SEARCH OF A UNIFYING PRINCIPLE”?

    Directory of Open Access Journals (Sweden)

    Susan Raeker-Jordan

    2011-05-01

    Full Text Available In Kennedy v. Louisiana, the United States Supreme Court held unconstitutional a state law that provided for the imposition of death upon one convicted of raping, but not killing or attempting to kill, a child. Justice Anthony Kennedy wrote the opinion for the Court, in which the majority, employing various analytical tools, brought its "own judgment" to bear on the excessiveness, and therefore the constitutionality, of the death sentence under the Eighth Amendment's Cruel and Unusual Punishments Clause. In emphasizing the Court's use of its own judgment in making the determination of excessiveness or disproportionality, Justice Kennedy and the majority risked the same public and internal dissenting Court criticisms that accompanied previous death penalty opinions in which Court majorities and pluralities similarly employed their own judgments. In the sharp divide over these issues, critics have accused those jurists of disguising their personal views of morality as the doctrinal application of their "own judgment" on these questions. This article argues that despite the criticisms and despite the Court's statement that at least some of its capital punishment case law is "still in search of a unifying principle," there is a precedential thread unifying and justifying the Court's own assessment of excessiveness under the Eighth Amendment. Historical analysis of the Court's Eighth Amendment statements shows that the clear thread in the cases is respect for human dignity and restraint, which plays out through the Amendment's proportionality guarantee. The Court's application of that guarantee against excessiveness has, time and again, invoked the Court's own judgment, based on  contemporary knowledge of punishment, of punishment's goals, and about decency in punishment. This article argues that that approach is sound and historically rooted, and that the Court should continue to apply its own judgment about decency, excessiveness, and

    The World Health Assembly (WHA) is the decision-making body of the World Health Organization. Delegates attending the Sixty-Eighth WHA, May 2015, covered a wide range of global challenges and agreed on several key resolutions of importance to nurse leaders. Some of the resolutions adopted relevant for nurse leaders and nursing care such as air pollution, strategies to strengthen epilepsy care, antimicrobial drug resistance, and strategies to strengthen surgical care, are highlighted. Nurse leaders should consider attending the World Health Assembly, as the topics discussed are critical for the future directions of strengthening human resources for health worldwide and, in particular, nursing and midwifery services.

  7. Eighth-order phase-field-crystal model for two-dimensional crystallization

    Jaatinen, A.; Ala-Nissilä, Tapio

    2010-01-01

    We present a derivation of the recently proposed eighth-order phase-field crystal model [A. Jaatinen et al., Phys. Rev. E 80, 031602 (2009)] for the crystallization of a solid from an undercooled melt. The model is used to study the planar growth of a two-dimensional hexagonal crystal, and the results are compared against similar results from dynamical density functional theory of Marconi and Tarazona, as well as other phase-field crystal models. We find that among the phase-field crystal mod...

    Full Text Available In this paper we have constructed an optimal eighth-order method with four function evaluations to solve the non-linear equations. The proposed method is a three-step method in which no derivative is required. Our scheme is optimal in the sense of Kung and Traub. Moreover, some test functions have been also included to confirm the superiority of the proposed method. At the end, we have presented the basins of attraction of some existing methods along with our proposed method to illustrate their performances.

    2013-01-01

    Full Text Available A family of eighth-order iterative methods for solution of nonlinear equations is presented. We propose an optimal three-step method with eight-order convergence for finding the simple roots of nonlinear equations by Hermite interpolation method. Per iteration of this method requires two evaluations of the function and two evaluations of its first derivative, which implies that the efficiency index of the developed methods is 1.682. Some numerical examples illustrate that the algorithms are more efficient and performs better than the other methods.

    Arkwright, Ashlie Beals

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

    Peng, Li-Wei

    2009-12-01

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

    2017-01-01

    Chorea-Acanthocytosis (ChAc) is a rare hereditary neurological disorder characterized by abnormal movements, red blood cell pathology, and progressive neurodegeneration. Little is understood of the pathogenesis of ChAc and related disorders (collectively Neuroacanthocytosis). The Eighth International Chorea-Acanthocytosis Symposium was held in May 2016 in Ann Arbor, MI, USA, and focused on molecular mechanisms driving ChAc pathophysiology. Accompanying the meeting, members of the neuroacanthocytosis research community and other invited scientists met in a workshop to discuss the current understanding and next steps needed to better understand ChAc pathogenesis. These discussions identified several broad and critical needs for advancing ChAc research and patient care, and led to the definition of 18 specific action points related to functional and molecular studies, animal models, and clinical research. These action points, described below, represent tractable research goals to pursue for the next several years. PMID:28224046

    2015-10-01

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

    2014-12-01

    We quantitatively investigated the eighth century heavy metal pollution in Heijo-kyo (Ancient Nara), the first large, international city of Japan. In this metropolis, mercury, copper, and lead levels in soil were increased by urban activity and by the construction of the Great Buddha statue, Nara Daibutsu. Mercury and copper pollution associated with the construction of the statue was particularly high in the immediate vicinity of the statue, but markedly lower in the wider city environment. We therefore reject the hypothesis that extensive mercury pollution associated with the construction of the Nara Daibutsu made it necessary to abandon Ancient Nara, even though severe lead pollution was detected at several sites. The isotopic composition of the lead indicated that it originated mainly from the Naganobori mine in Yamaguchi, which was a major source of the copper for the Nara Daibutsu.

    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.

    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.

    1981-08-01

    The design of a source is described which is suitable for making speech recordings in eighth-scale acoustic models of auditoria. An attempt was made to match the directionality of the source with the directionality of the human voice using data reported in the literature. A narrow aperture was required for the design which was provided by mounting an inverted conical horn over the diaphragm of a high frequency loudspeaker. Resonance problems were encountered with the use of a horn and a description is given of the electronic techniques adopted to minimize the effect of these resonances. Subjective and objective assessments on the completed speech source have proved satisfactory. It has been used in a modelling exercise concerned with the acoustic design of a theatre with a thrust-type stage.

  20. Analyzing Turkey's data from TIMSS 2007 to investigate regional disparities in eighth grade science achievement

    Science.gov (United States)

    Erberber, Ebru

    Turkey is expected to be a full member of the European Union (EU) by 2013. 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.

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

    Science.gov (United States)

    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).

    In the interval between the publication of the seventh and eighth editions of the Guide for the Care and Use of Laboratory Animals (Guide), much has changed with regard to the regulation and funding of highly pathogenic biologic agents and toxins (Select Agents). Funding of research involving highly pathogenic agents has increased dramatically during this time, thus increasing the demand for facilities capable of supporting this work. The eighth edition of the Guide briefly mentions Select Agents and provides a limited set of references. Here we provide some background information regarding the relevant laws and regulations, as well as an overview of the programmatic requirements pertaining to the use of Select Agents, with a focus on use in animals.

    2007-01-01

    We have carried out a new evaluation of the eighth-order contribution to the electron g-2 using FORTRAN codes generated by an automatic code generator gencodeN. Comparison of the "new" result with the "old" one has revealed an inconsistency in the treatment of the infrared divergences in the latter. With this error corrected we now have two independent determinations of the eighth-order term. This leads to the revised value 1 159 652 182.79 (7.71) x 10^{-12} of the electron g-2, where the uncertainty comes mostly from that of the best non-QED value of the fine structure constant alpha. The new value of alpha derived from the revised theory and the experiment is alpha^{-1} = 137.035 999 070 (98), which is about 4.7 ppb smaller than the previous alpha^{-1}.

    2016-01-01

    Full Text Available The purpose of this paper is to develop a high-order compact finite difference method for solving one-dimensional (1D heat conduction equation with Dirichlet and Neumann boundary conditions, respectively. A parameter is used for the direct implementation of Dirichlet and Neumann boundary conditions. The introduced parameter adjusts the position of the neighboring nodes very next to the boundary. In the case of Dirichlet boundary condition, we developed eighth-order compact finite difference method for the entire domain and fourth-order accurate proposal is presented for the Neumann boundary conditions. In the case of Dirichlet boundary conditions, the introduced parameter behaves like a free parameter and could take any value from its defined domain but for the Neumann boundary condition we obtained a particular value of the parameter. In both proposed compact finite difference methods, the order of accuracy is the same for all nodes. The time discretization is performed by using Crank-Nicholson finite difference method. The unconditional convergence of the proposed methods is presented. Finally, a set of 1D heat conduction equations is solved to show the validity and accuracy of our proposed methods.

    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.

  9. Where students turn into teachers: the eighth Inverted CERN School of Computing

    2015-01-01

    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...

  10. An evaluation of the National Curriculum Redesign Project: Eighth grade science curriculum pedagogical strategies

    Chalwell-Brewley, Lavon P.

    The purpose of this study was to examine the effectiveness of the eighth grade science National Curriculum Redesign Project. The site for this study was an urban secondary school in the British Virgin Islands. The school's population consisted of 1600 students and 120 teachers, where approximately 70% of the students were from low socioeconomic families (Secondary High School Statistical Records, 2006). The school's population was tri-cultural and consisted of approximately more Black West Indian, than Hispanic and Caucasian students and teachers. The school employed a student centered and pedagogical approach. The classroom's structure comprised of heterogeneously grouped inclusion classes with class sizes ranging between 27--40 students. The results of several studies revealed that the school's graduates did not have vital skills to work and effectively function in the work place (Organization of Eastern Caribbean States, 2000). These findings challenged the curriculum attributes and the school's pedagogical practices as it relates to providing powerful discourse in good instruction and improved academic achievement skills. Thus, the National Curriculum Redesign Project was developed to ensure teaching-learning components work together to foster significant learning practices. The review of the literature informed and substantiated the research and the related research questions. The population sample consisted of three secondary school science teachers and 26 students. Questionnaires and interview data collecting tools were employed. The data was analyzed to identify patterns and themes in responses. Descriptive statistics consisting of frequencies and percentage were used to support qualitative information and recommendations were made.

    2013-01-01

    Increasingly, Elsevier's HESI Exit Exam (E(2)) is being used to assess students' readiness for the National Council Licensure Examination for Registered Nurses (NCLEX-RN). Seven previously conducted validity studies indicate that the E(2) is 96.36%-99.16% accurate in predicting NCLEX-RN success. Findings of this eighth validity study, which also investigated the predictive accuracy of repeat testing with parallel versions of the E(2), indicated that the E(2) is highly accurate (94.93%-98.32%) in predicting NCLEX-RN success for the initial testing and 2 retests. Of the 66 participating nursing programs, deans and directors from 43 (65.15%) of the programs reported implementing a policy that used E(2) scores as a benchmark for remediation. A score of 850 was the most common E(2) benchmark designated by faculties, and students who failed to achieve the faculty-designated E(2) benchmark score were required to retest with a parallel version of the E(2). Remediation resources used to assist students in achieving faculty-designated E(2) benchmark scores varied widely, with many programs employing multiple remediation methods.

    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.

    The Eighth Annual Frontiers in Cancer Prevention Research meeting was held in Houston, Texas, in November 2009. This report highlights significant presentations that advance the fields of chemoprevention, clinical trial recruitment and retention, cancer screening including optical imaging, energy balance, and nutritional epidemiology, and health communications and decision making. In findings from the randomized Reduction by Dutasteride of Prostate Cancer Events trial, dutasteride reduced the risk of biopsy-detectable prostate cancer in high-risk men by 23% compared with placebo. Important clues about the dosing and window of susceptibility for supplementation with choline, vitamin D, and folate were revealed from epigenetic research that has implications for future nutritional epidemiology research. Noninvasive optical imaging techniques using endoscopic ultrasound and autofluorescence for the early detection of cancers in the lung, pancreas, and oral cavity are being studied. The report also addresses the challenges of promoting cancer prevention. Understanding how individuals process risk information and make sustained behavior changes and the effect of socioeconomic status on health disparities were identified as critical areas of research. This multidisciplinary research meeting of basic, clinical, and behavioral scientists and epidemiologists continues to play a major role in identifying the research priority areas of cancer prevention, elucidating new mechanisms of carcinogenesis for targeted chemoprevention therapies and delivering a comprehensive strategy for engaging individuals in the unifying goal to reduce cancer incidence. 2010 AACR.

    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.

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

    2014-01-01

    The Fenna-Matthews-Olson (FMO) protein-pigment complex acts as a molecular wire between the outer antenna system and the reaction center (RC); it is an important model system to study the excitonic energy transfer. Recent crystallographic studies report the existence of an additional (eighth) bacteriochlorophyll a (BChl a). To understand the functionality of this eighth BChl, we simulated the two-dimensional electronic spectra of both the 7-site (apo form) and the 8-site (holo form) variant of the FMO complex from green sulfur bacteria, Prosthecochloris aestuarii. By comparing the difference between the spectrum, it was found that the eighth BChl can affect two different excitonic energy transfer pathways, these being: (1) directly involve in the first pathway 6 $\\rightarrow$ 3 $\\rightarrow$ 1 of the apo form model by passing the excitonic energy to exciton 6; and (2) increase the excitonic wave function overlap between excitons 4 and 5 in the second pathway (7 $\\rightarrow$ 4,5 $\\rightarrow$ 2 $\\rightarrow$ ...

    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.

  2. Nonadditive three-body potential and third to eighth virial coefficients of carbon dioxide

    Hellmann, Robert

    2017-02-01

    A new nonadditive three-body interaction potential for carbon dioxide was determined from supermolecular ab initio calculations up to the coupled cluster with single, double, and perturbative triple excitations [CCSD(T)] level of theory for 9401 configurations. A physically motivated analytical function with terms for describing nonadditive dispersion, induction, and exchange contributions was fitted to the calculated nonadditive three-body interaction energies. For the 7996 configurations with a total interaction energy of less than 3000 K, the mean absolute error of the analytical function is 0.32 K. The new nonadditive three-body potential was applied together with a previously published pair potential [R. Hellmann, Chem. Phys. Lett. 613, 133 (2014)] to calculate the third to seventh virial coefficients of CO2 at subcritical and supercritical temperatures up to 2000 K. The eighth virial coefficient was also calculated, but using only the pair potential and only at temperatures from 600 K to 2000 K because of the enormous computational costs. A simple analytical function was fitted individually to the calculated values of each virial coefficient, including previously determined values of the second virial coefficient, to obtain an analytical virial equation of state (VEOS). For densities at which the VEOS is converged, the agreement in pressure with the reference EOS of Span and Wagner [J. Phys. Chem. Ref. Data 25, 1509 (1996)] is mostly within ±0.5 % . However, for temperatures above about 700 K, much larger deviations occur at higher densities, which we ascribe mainly to deficiencies of the reference EOS due to the lack of accurate data for these experimentally difficult conditions.

    The National Institute for Occupational Safety and Health (NIOSH) National Personal Protective Technology Laboratory (NPPTL) and the Mine Safety and Health Administration (MSHA) conduct a Long Term Field Evaluation (LTFE) program to evaluate deployed self-contained self rescuers (SCSRs). The objective of the program is to evaluate how well SCSRs endure the underground coal mining environment with regard to both physical damage and aging when they are deployed in accordance with Federal regulations (30 CFR 75.1714). This report presents findings of the combined eighth and ninth phases of the LTFE. For these phases, over four hundred SCSRs were evaluated. The units tested include the CSE SR-100, Draeger Oxy K-Plus, MSA Life-saver 60, and the OCENCO EBA 6.5. The OCENCO 20 was evaluated only in Phase 9. Testing was performed between December 2000 and April 2004. Results of the evaluation indicate that all SCSRs experience some performance degradation due to the mining environment. Observed degradation varies from elevated levels of carbon dioxide, high breathing resistance, and reduced capacity. Mechanical degradation to the SCSR components included breathing hoses, chemical beds, outer cases and seals. The LTFE tests discussed in this report are different from tests performed for SCSR certification to the requirements of 42 Code of Federal Regulations, Part 84 (42 CFR, Part 84). LTFE tests reported here are conducted to an end point, oxygen depletion, to enable comparison of the duration of new and deployed SCSRs. The method for obtaining deployed SCSRs for this evaluation was not a random selection from the deployed population of SCSRs. Although the results of these tests are useful for observing performance of the tested SCSRs, they are not representative of all deployed SCSRs. 9 refs., 10 figs., 9 tabs., 3 apps.

    2017 marks the eighth International Observe the Moon Night (InOMN), which will be held on July 15, 2017. We will present findings from the first seven years, including the most recent figures from the October 2016 event, and provide an overview of the 2017 events which will support the Great American Eclipse which occurs about five weeks later, on August 21, 2017.InOMN is an annual worldwide public event that encourages observation, appreciation, and understanding of our Moon and its connection to NASA planetary science and exploration. This year InOMN’s event will support broad efforts to promote the eclipse by providing resources to help InOMN hosts highlight lunar science that will influence the eclipse, such as the topography of the Moon, which affects the edges of the eclipse path and the location and duration of Baily’s beads. The InOMN team will host webinars to discuss the Moon, lunar science, and lunar and solar eclipses.Each year, thousands of visitors take part in hundreds of events across the world. In the first seven years (2010 to 2016) over 3,700 events were registered worldwide and hosted by a variety of institutions including astronomy clubs, observatories, schools, and universities and held at a variety of public and private institutions all over the world including museums, planetaria, schools, universities, observatories, parks, and private businesses and homes. Evaluation of InOMN reveals that events are raising visitors’ awareness of lunar science and exploration, providing audiences with information about lunar science and exploration, and inspiring visitors to want to learn more about the Moon and providing connections to opportunities to do so.InOMN is sponsored by NASA's Lunar Reconnaissance Orbiter, NASA's Solar System Exploration Research Virtual Institute (SSERVI), and the Lunar and Planetary Institute.

  5. Can virtual field trips be substituted for real-world field trips in an eighth grade geology curriculum?

    Science.gov (United States)

    Lewis, Daniel B.

    This study compares student learning from a real-world field trip with student learning from a virtual field trip. A field trip was designed to show students the way geologists believe the Grand Coulee in eastern Washington State was created. A real-world version and a virtual version (panoramic photographs) were constructed. Participants in the study were eighth grade Earth Science students. At the end of the study it was found that there was no significant difference on the final assessment between the scores of real-world field trip participants and the scores of virtual field trip participants.

  6. 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

  7. Students' learning approaches and their understanding of some chemical concepts in eighth-grade science

    Science.gov (United States)

    Chin, Christine Hui Li

    The purpose of this study was to (a) investigate the relationship between students' learning approaches and their conceptual understanding of some chemical concepts, (b) describe the qualitative differences between a deep and surface learning approach to learning science, and (c) identify the kinds of cognitive and metacognitive strategies that students use as they construct their conceptual knowledge. One hundred and two eighth grade students were given the Learning Approach Questionnaire to measure their orientation to learn using a deep or surface approach. They also completed a Chemistry Questionnaire both before and after the teaching of a chemistry unit which lasted nine weeks. Six target students from one class were selected for more in-depth study. They represented learners using a deep or surface learning approach, and were identified by the Learning Approach Questionnaire and their teacher's evaluation. They worked in groups during hands-on laboratory activities and were audiotaped or videotaped. The students were also interviewed individually both before and after instruction of the chemistry unit about their responses on the Chemistry Questionnaire and their thoughts and actions during the laboratory activities. The correlation between the students' scores on the "meaningful orientation" scale of the Learning Approach Questionnaire and their gain scores from the pre-test to post-test on the Chemistry Questionnaire was.06, suggesting no relationship between the students' learning approach and their conceptual change. Several reasons were given to explain this finding. Analysis of the target students' discourse and actions during the group activities and their interview responses revealed differences between the deep and surface learning approaches regarding generative thinking, nature of explanations, asking questions, metacognitive activity, and approach to tasks. Strategies associated with a deep learning approach included generating mental images and

  8. The understandings and meanings eight seventh and eighth grade Latinas gave to science

    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

  9. Pain management standards in the eighth edition of the Guide for the Care and Use of Laboratory Animals.

    Science.gov (United States)

    Carbone, Larry

    2012-05-01

    The eighth edition Guide for the Care and Use of Laboratory Animals sets standards for diverse laboratory animal care and use practices. It frames its standards as performance, engineering, and practice standards, with a strong emphasis on performance standards, allowing for multiple routes to clearly defined outcomes. Standards intended to be upheld rigorously are indicated through the use of must in the description, and those accommodating more flexibility are indicated through may and should statements. With respect to pain management standards, a fourth type of standard-the jurisdictional standard-has been prevalent through all 8 editions of the Guide. Under jurisdictional standards, specific methods and outcomes for measuring, preventing, or alleviating pain are not detailed, but the various jurisdictions of veterinarian, investigator, and IACUC are elaborated. Although data on pain management in laboratory animals has expanded greatly since the 1996 Guide, the eighth (2011) edition does not contain major new standards or guidance regarding animal pain management. Requirements for veterinary and IACUC involvement remain as in prior editions, and the duty of veterinarians and scientists to stay abreast of new developments is expected to drive refinement of animal pain management institution by institution. The current article details selected specific pain management standards in the 2011 Guide, lists topics in pain management for which the Guide does not set clear standards, and suggests possible standards for those topics.

    Full Text Available A collocation method based on the second kind Chebyshev wavelets is proposed for the numerical solution of eighth-order two-point boundary value problems (BVPs and initial value problems (IVPs in ordinary differential equations. The second kind Chebyshev wavelets operational matrix of integration is derived and used to transform the problem to a system of algebraic equations. The uniform convergence analysis and error estimation for the proposed method are given. Accuracy and efficiency of the suggested method are established through comparing with the existing quintic B-spline collocation method, homotopy asymptotic method, and modified decomposition method. Numerical results obtained by the present method are in good agreement with the exact solutions available in the literatures.

    The present study uses an ecological systems perspective to examine how parental involvement in school-related activities in sixth grade influences early adolescents' school bonding and academic achievement in eighth grade. Results of multilevel models of multiple data sources (i.e., adolescents, parents, and principals) suggested that parents' involvement in school, as reported by the adolescent in sixth grade, was a significant predictor of school bonding and academic grades in eighth grade. Furthermore, parent reports of guidance, support, and involvement in school and non-school activities were unrelated to their adolescents' grades and school bonding. Finally, schools' efforts to engage parents did not consistently predict an association between parental involvement and adolescent outcomes.

    The International Association for the Study of Lung Cancer has proposed a revision of the Tumor, Node, Metastasis (TNM) classification for lung cancer. The purpose of this study is to evaluate the prognostic value of the eighth edition of the TNM staging system in surgically treated patients with non-small-cell lung cancer. Data from 2043 consecutive patients with non-small-cell lung cancer who underwent surgical treatment in our single center between January 2006 and September 2015 were collected and analyzed retrospectively. Cox proportional hazard models were used to assess the prognostic significance of the T and N descriptors. The reversed overall survival curves of stage IIA and stage IIB in the seventh edition were corrected in the eighth edition. Better prognostic value in predicting overall survival, including a higher log rank test of trend χ(2) statistic (433.6 vs. 414.2), a smaller Akaike Information Criterion value (4759.6 vs. 4768.2), a higher Harrell C-index (0.776 vs. 0.769), and a lower integrated Brier score (0.092 vs. 0.093), was observed for the eighth edition relative to the seventh edition. Recurrence-free survival analysis of subsets of patients stratified by T and N descriptors showed a stepwise deterioration. Significant differences were found between patients of subdivided stage IA (IAI vs. IA2; P = .003 and IA2 vs. IA3; P = .004). The eighth edition of the TNM staging system for lung cancer has prognostic value superior to that of the seventh edition. It was able to predict recurrence-free survival well.

    Full Text Available In this study, opinions of primary school students about science-technology-society-environment and relation of these opinions in terms of many variables are analysed. In this research, it was used of individual survey model from the general survey model. Total 408 students, as 228 of them are girls and 180 of them are boys attending to two state one private school during the first term of school year of 2010-2011 in Antalya constitute the study group of research. Student questionnaire about the subjects of STSE developed by the researchers as data collection tool was applied to sixth, seventh and eighth grade students in the research. In this study, students of second grade tend to choose agree and totally agree regarding to the questionnaire items of STSE subjects. Moreover, it is found out that there is determined significant relationship between some items and sex variable when Cramer V coefficient values are analyzed to determine the relation between opinions about STSE and sex variable. It is seen that girls participated in STSE subjects more than boys considering these items in general. In this study, there is determined significant relationship between some items and school type of students considering Cramer V coefficient values to determine the relation between opinions of participants about STSE and variable of school type. Students of private school tend to choose agree and totally agree regarding to the questionnaire items of STSE subjects more than state schools’ students.

    Aoyama, Tatsumi; Kinoshita, Toichiro; Nio, Makiko

    2011-01-01

    This paper reports the evaluation of the tenth-order QED contribution to the lepton g-2 from the gauge-invariant set of 2072 Feynman diagrams, called Set IV, which are obtained by inserting a second-order lepton vacuum-polarization loop into 518 eighth-order vertex diagrams of four-photon exchange type. The numerical evaluation is carried out by the adaptive-iterative Monte-Carlo integration routine vegas using the fortran codes written by the automatic code-generating algorithm gencodeN. Some of the numerical results are confirmed by comparison with the values of corresponding integrals that have been obtained previously by a different method. The result for the mass-independent contribution of the Set IV to the electron g-2 is $-7.7296 (48) (\\alpha/\\pi)^5$. There is also a small mass-dependent contribution to the electron g-2 due to the muon loop: $-0.01136 (7) (\\alpha/\\pi)^5$. The contribution of the tau-lepton loop is $-0.0000937(104)(\\alpha/\\pi)^5$. The sum of all these contributions to the electron g-2 ...

    2010-01-01

    This paper reports the Feynman-parametric representation of the vacuum-polarization function consisting of 105 Feynman diagrams of the eighth order, and its contribution to the gauge-invariant set called Set I(i) of the tenth-order lepton anomalous magnetic moment. Numerical evaluation of this set is carried out using FORTRAN codes generated by an automatic code generation system gencodevpN developed specifically for this purpose. The contribution of diagrams containing electron loop to the electron g-2 is 0.017 47 (11) (alpha/pi)^5. The contribution of diagrams containing muon loop is 0.000~001 67 (3) (alpha/pi)^5. The contribution of tau-lepton loop is negligible at present. The sum of all these terms is 0.017 47 (11) (alpha/pi)^5. The contribution of diagrams containing electron loop to the muon g-2 is 0.087 1 (59) (alpha/pi)^5. That of tau-lepton loop is 0.000 237 (1) (alpha/pi)^5. The total contribution to a_mu, the sum of these terms and the mass-independent term, is 0.104 8 (59) (alpha/pi)^5.

An automatic frequency tuning circuit is introduced to compensate the cut-off frequency variation using a 6-bit switched-capacitor array. Switched-resistor arrays are adopted to cover different cut-off frequencies in low-IF and zero-IF modes. Measurement results show that precise cut-off frequencies at 2.5, 3, 3.5 and 4 MHz in zero-IF mode, 5, 6, 7 and 8 MHz in low-IF mode can be achieved, 60 dB frequency attenuation can be obtained at 20 MHz, and the in-band group delay agrees well with the simulation. Two-tone testing shows the in-band IM3 achieves -52 dB and the out-band IM3 achieves -55 dB with -11 dBm input power.This proposed filter circuit, fabricated in a SMIC 0.18 μm CMOS process, consumes 4 mA current with 1.8 V power supply.

    The purpose of the present study was to explore the relationship between family meals and parental encouragement of healthy eating overall and by ethnicity. Family meal frequency was measured with one item asking how many times in the past 7 d all or most of the family ate a meal together, which was then categorized to represent three levels of family meals (≤2 times, 3-6 times and ≥7 times). Parental encouragement of healthy eating assessed how often parents encouraged the student to eat fruits and vegetables, drink water, eat wholegrain bread, eat breakfast and drink low-fat milk (never to always). An overall scale of parental encouragement of healthy eating was created. Mixed-effect regression analyses were run controlling for gender, ethnicity, age and socio-economic status. Moderation by ethnicity was explored. Middle schools. Participants included 2895 US eighth grade students participating in the Central Texas CATCH (Coordinated Approach To Child Health) Middle School Project (mean age 13·9 years; 24·5 % White, 52·7 % Hispanic, 13·0 % African-American, 9·8 % Other; 51·6 % female). Eating more family meals was significantly associated with having parents who encouraged healthy eating behaviours (P for trend healthy eating behaviours (P for trend eat together are more likely to encourage healthy eating in general. Interventions which promote family meals may include tips for parents to increase discussions about healthy eating.

    The evolution of organ transplantation has produced results so successful that many transplant programs commonly see recipients with medical risks, which in the past, would have prohibited transplantation. The Eighth Annual American Society of Transplant Surgeons State-of-the-Art Winter Symposium focused on the high-risk recipient. The assessment of risk has evolved over time, as transplantation has matured. The acceptance of risk associated with a given candidate today is often made in consideration of the relative value of the organ to other candidates, the regulatory environment, and philosophical notions of utility, equity, and fairness. In addition, transplant programs must balance outcomes, transplant volume, and the costs of organ transplantation, which are impacted by high-risk recipients. Discussion focused on various types of high-risk recipients, such as those with coronary artery disease, morbid obesity, and hepatitis C; strategies to reduce risk, such as down-staging of hepatocellular carcinoma and treatment of pulmonary hypertension; the development of alternatives to transplantation; and the degree to which risk can or should be used to define candidate selection. These approaches can modify the impact of recipient risk on transplant outcomes and permit transplantation to be applied successfully to a greater variety of patients.

    The primary goal of the eighth industrial fluid properties simulation challenge was to test the ability of molecular simulation methods to predict the adsorption of organic adsorbates in activated carbon materials. The challenge focused on the adsorption of perfluorohexane in the activated carbon standard BAM-P109 (Panne and Thünemann 2010). Entrants were challenged to predict the adsorption of perfluorohexane in the activated carbon at a temperature of 273 K and at relative pressures of 0.1, 0.3, and 0.6. The relative pressure (P/Po) is defined as that relative to the bulk saturation pressure predicted by the fluid model at a given temperature (273 K in this case). The predictions were judged by comparison to a set of experimentally determined values, which are published here for the first time and were not disclosed to the entrants prior to the challenge. Benchmark experimental studies, described herein, were also carried out and provided to entrants in order to aid in the development of new force fields and simulation methods to be employed in the challenge. These studies included argon, carbon dioxide, and water adsorption in the BAM-P109 activated carbon as well as X-ray diffraction, X-ray microtomography, photoelectron spectroscopy, and atomic emission spectroscopy studies of BAM-P109. Several concurrent studies were carried out for the BAM-P108 activated carbon (Panne and Thünemann 2010). These are included in the current manuscript for comparison. PMID:27840543

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

    The long-term goal of this study was to increase the researcher's knowledge in curriculum content, curriculum design, and implementation, as well as teaching methodologies in the content areas for urban African American middle school students. The purpose of this specific study was to develop, implement and evaluate a reading in the content areas science curriculum designed to increase conceptual abilities, reading skills, and individual learning for eighth grade-students in urban schools. The research question that drove the goal and purpose of this study was as follows: How does the theory and practice of accelerated learning, multiple intelligences, and brain-based learning integrated with specific components of reading in the content area impact urban, middle school African American students' conceptual understanding of eighth-grade science? The student participants in this study were 16 African American students in the eighth grade who had below-grade reading achievement (third-grade level on district standardized tests), who were overage for middle school, yet still in the eighth grade, and who had failed the district's eighth grade science curriculum. This was an action-oriented research study that utilized a mixed methodology of qualitative and quantitative data collection. The quantitative data collection consisted of pre and post tests, surveys with yes/no responses, and graphs. The qualitative data collection consisted of surveys with written responses, and a focus group. The major finding from this study was that the dynamic interaction of the theories (accelerated learning, multiple intelligences, and brain-based learning integrated with specific components of reading in the content area) put into practice through the Michigan Framework Curriculum had a significant impact on student learning as evidenced by the MAT-7 standardized test scores. Qualitative findings indicated that this dynamic interaction of theories put into practice worked to create a

    The purpose of this paper is to examine whether children who care for themselves for longer periods of time are at increased risk of poor grades, truancy, anger, family conflict, stress, risk-taking, and peer influences (in addition to the increased risk of substance use previously reported). Demographic characteristics of eighth-grade students who initiate self-care in junior high school are compared with those initiating self-care in elementary school. Further, increased risks for those initiating self-care in elementary school are examined. Over two thirds of the respondents (67.8%) cared for themselves after school without adult supervision at some time during the week; 23.5% for 1 to 4 hours per week, 15.7% for 5 to 10 hours per week, and 28.6% for 11 or more hours per week. Of those in self-care, 48.5% initiated self-care during elementary school and 51.5% during junior high school. Students who were in the highest category of self-care (greater than or equal to 11 hours per week) vs those in self-care zero hours per week were 1.5 to 2 times as likely to score high on risk-taking, anger, family conflict, and stress, to be more likely to see their friends as their major source of influence, and to attend more parties. The self-reports of academic grades did not differ. The grade of initiation of self-care (elementary vs junior high school) conferred additional risk for drinking alcohol (odds ratio = 1.4), risk-taking tendencies (odds ratio = 1.5), and attending parties (odds ratio = 1.6).

    Full Text Available Background: Hypertension is a common medical disease, occurring in about one third of young adults and almost two thirds of individuals over the age of 60. With the release of the Eighth Joint National Committee on Prevention, Detection, Evaluation, and Treatment (JNC-8 guidelines, there have been major changes in blood pressure management in the various subgroups. Aim: Optimal blood pressure management and markers of end-organ damage in African-American adult patients were compared between patients who were managed according to the JNC-8 hypertension management guidelines and those who were treated with other regimens. Materials and Methods: African-American patients aged 18 years or older with an established diagnosis of hypertension were included in the study who were followed up in our internal medicine clinic between January 1, 2013 and December 31, 2103; the data on their systolic and diastolic blood pressure readings, heart rate, body mass index (BMI, age, gender, comorbidities, and medications were recorded. Patients were divided into four groups based on the antihypertensive therapy as follows - Group 1: Diuretic only; Group 2: Calcium channel blocker (CCB only; Group 3: Diuretic and CCB; Group 4: Other antihypertensive agent. Their blood pressure control, comorbidities, and associated target organ damage were analyzed. Results: In all 323 patients, blood pressures were optimally controlled. The majority of the patients (79.6% were treated with either a diuretic, a CCB, or both. Intergroup comparison analysis showed no statistically significant difference in the mean systolic blood pressure, mean diastolic blood pressure, associated comorbidities, or frequency of target organ damage. Conclusion: Although diuretics or CCBs are recommended as first-line agents in African-American patients, we found no significant difference in the optimal control of blood pressure and frequency of end-organ damage compared to management with other agents.

    Several studies have demonstrated that the seventh edition of the American Joint Committee on Cancer/American Joint Committee on Cancer (AJCC/UICC) TNM staging system does not consistently distinguish between prognostic subgroups for human papillomavirus (HPV)-mediated oropharyngeal squamous cell carcinoma (OPSCC). The eighth edition of the AJCC/UICC TNM staging system came into effect for use with HPV-mediated OPSCC on or after 1 January 2017. This study confirms that the eighth edition of the AJCC/UICC TNM staging system for HPV-mediated OPSCC accurately reflects disease outcomes. We retrospectively analyzed 195 patients with OPSCC treated at Hokkaido University Hospital, Sapporo, Japan between 1998 and 2015. HPV status was evaluated by immunohistochemical analysis of p16. Of the 195 OPSCC patients evaluated, 111 (56.9%) were p16 positive and 84 (43.1%) were p16 negative. The 3-year overall survival rate (OS) was significantly lower in the p16-negative patients with stage III-IV in comparison with those with stage I-II (55.0 vs. 93.1%, respectively; p TNM staging system, stage I-II and stage III can be differentiated on the basis of the 3-year OS in the p16-positive patients (90.9 vs 70.2%, respectively; p TNM staging system is suitable for use with p16-negative patients; however, it does not effectively discriminate between p16-positive patients. Therefore, the eighth edition of the AJCC/UICC TNM staging system is more suitable for HPV-mediated OPSCC in Japan.

    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.

    Thymic epithelial tumors (TETs) are rare intrathoracic malignancies that are categorized histologically according to the WHO classification, which was recently updated in 2015 on the basis of a consensus statement of the International Thymic Malignancy Interest Group (ITMIG); at the same time, the standard Masaoka-Koga staging system is scheduled to be replaced by the eighth edition of the TNM staging classification by the American Joint Committee on Cancer/Union for International Cancer Control consortium. Our objectives were to analyze the feasibility of assessing ITMIG consensus major and minor morphological and immunohistochemical criteria and the eighth edition of the TNM staging classification in a routine practice setting. This is a single-center study conducted at the Louis-Pradel Hospital of Lyon University, one of the largest centers for TETs in France. Overall, a large surgical series of 188 TETs diagnosed in 181 patients between 2000 and 2014 at our center were analyzed. There were 89 men (49%) and 92 women (51%); 57 patients (31%) presented with myasthenia gravis at time of diagnosis. According to the WHO classification, there were nine type A thymomas (5%), 67 type AB thymomas (36%), 19 type B1 thymomas (10%), 46 type B2 thymomas (24%), 27 type B3 thymomas (14%), and 20 thymic carcinomas (11%). ITMIG consensus major criteria were identified in 100% of type A, AB, B1, and B2 thymomas. After restaging according to the eighth edition of the TNM staging classification, there were 127 stage I (84%), three stage II (2%), 17 stage IIIa (11%), no stage IIIb, two stage IVa (1%), and three stage IVb (2%) thymomas. Significant correlation between histological type and stage at diagnosis was maintained after restaging according the TNM classification. Comprehensive analysis of our well-characterized surgical series of 188 TETs indicates the feasibility and the diagnostic value of the ITMIG consensus statement on WHO histological classification and highlights the

    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 eighth edition of the Guide for the Care and Use of Laboratory Animals recognizes the widespread use of aquatic and semiaquatic research animals by including, among other references, an entire section on aquatic animals in its chapter on environment, housing, and management. Recognizing the large number of aquatic and semiaquatic species used in research and the inherent diversity in animal needs, the Guide refers the reader to texts and journal reviews for specific recommendations and suggests consultations with persons experienced in caring for aquatic species. Here we present considerations that may add to the basic information presented in the Guide and offer some recommendations that may be useful for aquatic animal model caregivers and researchers.

    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.

    The current T component for malignant pleural mesothelioma (MPM) has been predominantly informed by surgical data sets and consensus. The International Association for the Study of Lung Cancer undertook revision of the seventh edition of the staging system for MPM with the goal of developing recommendations for the eighth edition. Data elements including detailed T descriptors were developed by consensus. Tumor thickness at three pleural levels was also recorded. An electronic data capture system was established to facilitate data submission. A total of 3519 cases were submitted to the database. Of those eligible for T-component analysis, 509 cases had only clinical staging, 836 cases had only surgical staging, and 642 cases had both available. Survival was examined for T categories according to the current seventh edition staging system. There was clear separation between all clinically staged categories except T1a versus T1b (hazard ratio = 0.99, p = 0.95) and T3 versus T4 (hazard ratio = 1.22, p = 0.09), although the numbers of T4 cases were small. Pathological staging failed to demonstrate a survival difference between adjacent categories with the exception of T3 versus T4. Performance improved with collapse of T1a and T1b into a single T1 category; no current descriptors were shifted or eliminated. Tumor thickness and nodular or rindlike morphology were significantly associated with survival. A recommendation to collapse both clinical and pathological T1a and T1b into a T1 classification will be made for the eighth edition staging system. Simple measurement of pleural thickness has prognostic significance and should be examined further with a view to incorporation into future staging.

    To date, the Asia Cancer Forum has focused its efforts on creating a common concept for collaborative efforts in international cancer research with a focus on Asia, where cancer incidence is rising dramatically, and also sharing information and knowledge among cancer specialists about the importance of cancer as a global health agenda issue. The Eighth Asia Cancer Forum was held following the historic outcome of the High-level Meeting of the United Nations General Assembly on the Prevention and Control of Non-communicable Diseases held in New York in September 2011, at which cancer was duly recognized as a global health agenda issue. Despite this significant development, however, the issue of cancer, one of the most intractable of all non-communicable diseases, still faces a variety of challenges if it is to be addressed on the global level. The Eighth Asia Cancer Forum sought to address these various issues, seeking ways to capitalize on the outcomes of the UN Meeting and take global collaborative studies and alliances in the field of cancer further. It was recognized that one of the main challenges for the Asia Cancer Forum is to formulate a proposal that demonstrates how middle-income countries can provide a good level of care using only their own limited medical resources. Given that the Asia Cancer Forum is one of the organizations that can provide assistance in working to further boost awareness about cancer research and the situation relating to cancer in Asian countries, discussion also focused on how to concretize activities in the future.

    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.

    We have evaluated the contribution to the anomalous magnetic moment of the electron from six tenth-order Feynman diagrams which contain eighth-order vacuum-polarization function formed by two light-by-light scattering diagrams connected by three photons. The integrals are constructed by two different methods. In the first method the subtractive counter terms are used to deal with ultraviolet (UV) singularities together with the requirement of gauge-invariance. In the second method, the Ward-Takahashi identity is applied to the light-by-light scattering amplitudes to eliminate UV singularities. Numerical evaluation confirms that the two methods are consistent with each other within their numerical uncertainties. Combining the two results statistically and adding small contribution from the muons and/or tau leptons, we obtain $ 0.000 399 9 (18) (\\alpha/\\pi)^5$. We also evaluated the contribution to the muon $g-2$ from the same set of diagrams and found $ -1.263 44 (14) (\\alpha/\\pi)^5$.

    The Eighth Annual DOE (Department of Energy) Low-Level Waste Management Forum was held in September 1986, in Denver, Colorado, to provide a forum for exchange of information on low-level radioactive waste (LLW) management activities, requirements, and plans. The one hundred ninety attendees included representatives from the DOE Nuclear Energy and Defense Low-Level Waste Management Programs, DOE Operations Offices and their contractors; representatives from the US Nuclear Regulatory Commission (NRC), US Environmental Protection Agency (EPA), US Geological Survey, and their contractors; representatives of states and regions responsible for development of new commercial low-level waste disposal facilities; representatives of utilities, private contractors, disposal facility operators, and other parties concerned with low-level waste management issues. Plenary sessions were held at the beginning and conclusion of the meeting, while eight concurrent topical sessions were held during the intervening two days. The meeting was organized by topical areas to allow for information exchange and discussion on current and future low-level radioactive waste management challenges. Session chairmen presented summaries of the discussions and conclusions resulting from their respective sessions. Selected papers in this volume have been processed for inclusion in the Energy Data Base.

    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.

    An understanding of the scientific enterprise is useful because citizens need to make systematic, rational decisions about projects involving scientific endeavors and technology, and a clearer understanding of scientific epistemology is beneficial because it could encourage more public engagement with science. The purpose of this study was to capture beliefs for three groups, scientists, secondary science teachers, and eighth-grade science students, about the ways scientific knowledge is generated and validated. Open-ended questions were framed by formal scientific epistemology and dimensions of epistemology recognized in the field of educational psychology. The resulting statements were placed in a card sort and mapped in a network analysis to communicate interconnections among ideas. Maps analyzed with multidimensional scaling revealed robust connections among students and scientists but not among teachers. Student and teacher maps illustrated the strongest connections among ideas about experiments while scientist maps present more descriptive and well-rounded ideas about the scientific enterprise. The students' map was robust in terms of numbers of ideas, but were lacking in a hierarchical organization of ideas. The teachers' map displayed an alignment with the learning standards of the state, but not a broader view of science. The scientists map displayed a hierarchy of ideas with elaboration of equally valued statements connected to several foundational statements. Network analysis can be helpful in forwarding the study of views of the nature of science because of the technique's ability to capture verbatim statements from participants and to display the strength of connections among the statements.

    The most recent crystal structure of the Fenna-Matthews-Olson (FMO) protein complex indicates that each subunit contains an additional eighth chromophore. It has been proposed that this extra site functions as a link between the chlorosome antenna complex and the remaining seven chromophores in FMO [Schmidt am Busch et al, J. Phys. Chem. Lett., {\\bf 2}, 93 (2011)]. Here, we investigate the implications of this scenario through numerical calculations with the generalized Bloch-Redfield (GBR) equation and the non-interacting blip approximation (NIBA). Three key insights into the population dynamics and energy transfer efficiency in FMO are provided. First, it is shown that the oscillations that are often observed in the population relaxation of the dimer composed of sites one and two may be completely suppressed in the eight site model. The presence of the coherent oscillations is shown to depend upon the particular initial preparation of the dimer state. Secondly it is demonstrated that while the presence of t...

    Revisions to the TNM stage classifications for lung cancer, informed by the international database (N = 94,708) of the International Association for the Study of Lung Cancer (IASLC) Staging and Prognostic Factors Committee, need external validation. The objective was to externally validate the revisions by using the National Cancer Data Base (NCDB) of the American College of Surgeons. Cases presenting from 2000 through 2012 were drawn from the NCDB and reclassified according to the eighth edition stage classification. Clinically and pathologically staged subsets of NSCLC were analyzed separately. The T, N, and overall TNM classifications were evaluated according to clinical, pathologic, and "best" stage (N = 780,294). Multivariate analyses were carried out to adjust for various confounding factors. A combined analysis of the NSCLC cases from both databases was performed to explore differences in overall survival prognosis between the two databases. The databases differed in terms of key factors related to data source. Survival was greater in the IASLC database for all stage categories. However, the eighth edition TNM stage classification system demonstrated consistent ability to discriminate TNM categories and stage groups for clinical and pathologic stage. The IASLC revisions made for the eighth edition of lung cancer staging are validated by this analysis of the NCDB database by the ordering, statistical differences, and homogeneity within stage groups and by the consistency within analyses of specific cohorts.

    Osteoporosis and related fragility fractures represent a serious and global public health problem. To evaluate whether the modified eighth section of Eight-section Brocade (MESE) exercise could improve the symptom and indexes associated with osteoporosis in postmenopausal women. Guangzhou and Liuzhou hospital of traditional Chinese medicine in China. Women (n = 198) aged 50 to 75 years were randomized into Control, Ca, MESE, and MESE + Ca. Subjects in Ca and MESE groups were separately asked to consume thrice daily Calcium Carbonate Chewable D3 tablet and to perform thrice daily MESE exercise by 7 repetitions per time for 12 months. Subjects in MESE + Ca group performed such the combined treatment project for 12 months. Body height and Hospital for Special Surgery (HSS) scores of both knees, chronic back pain visual analogue scale scores (VAS), bone mineral density (BMD) at L2 to L4 and the left femoral neck, 3-feet Up and Go Test (3') and one-leg Stance (OLS). In our study, the improvement in chronic back pain of the patients in Ca, MESE, and MESE + Ca group was better than that in control group. There was 1.9% and 1.7%, 2.3%, and 2.1% net profit in left femoral neck and lumbar BMD after the treatment for 12 months in MESE and MESE + Ca groups. For the balance capacity, the subjects in MESE and MESE + Ca groups secured much better performance than those in Ca and control group after the treatment for 12 months (P exercise is the most effective for the improvement of the symptom and indexes in postmenopausal women. Importantly, the low attrition and the high exercise compliance indicate that MESE exercise is safe, feasible, and well tolerated by postmenopausal women.

    To determine the effect of growth under elevated CO(2) partial pressures (pCO(2)) on photosynthetic electron transport and photoprotective energy dissipation, we examined light-saturated net photosynthetic CO(2) assimilation (A(sat)), the capacity for photosynthetic O(2) evolution, chlorophyll fluorescence emission and the pigment composition of upper-canopy loblolly pine needles in the eighth year of exposure to elevated pCO(2) (20 Pa above ambient) at the free-air CO(2) enrichment facility in the Duke Forest. During the summer growing season, A(sat) was 50% higher in current-year needles and 24% higher in year-old needles in elevated pCO(2) in comparison with needles of the same age cohort in ambient pCO(2). Thus, photosynthetic down-regulation at elevated pCO(2) was observed in the summer in year-old needles. In the winter, A(sat) was not significantly affected by growth pCO(2). Reductions in A(sat), the capacity for photosynthetic O(2) evolution and photosystem II (PSII) efficiency in the light-acclimated and fully-oxidized states were observed in the winter when compared to summer. Growth at elevated pCO(2) had no significant effect on the capacity for photosynthetic O(2) evolution, PSII efficiencies in the light-acclimated and fully-oxidized states, chlorophyll content or the size and conversion state of the xanthophyll cycle, regardless of season or needle age cohort. Therefore, we observed no evidence that photosynthetic electron transport or photoprotective energy dissipation responded to compensate for the effects of elevated pCO(2) on Calvin cycle activity.

    Herein we report a description of gross and microscopic lesions found in specific pathogen-free chicken embryos caused by UNAM-97 infectious bronchitis virus (IBV) variant strain after the eighth passage. Embryos were divided into three groups and were inoculated in the chorioallantoic sac with 0.2 mL of UNAM-97, Mass 41 IBV (positive control), or sterile PBS (negative control). Forty-eight hours later the allatoic fluid was taken and used to start a cycle of eight passages through 9-d-old embryos. Seven days after the last passage, embryos were harvested and macroscopic lesions in all organs were recorded. Proventriculus and gizzard samples were obtained from all embryos and routinely processed for microscopic and ultrastructural examinations. The UNAM-97 IBV variant strain caused two macroscopic lesions uncommon for Mexican strains: thin-walled proventriculus and gizzard, as well as urate accumulation within an extra-embryonic peritoneal sac, leaving the body through the umbilical duct and accompanied by the yolk sac. At microscopic level, two relevant findings were observed to be produced by this variant. In the proventriculus, there was a decrease in the gland papillary branching, while the gizzard showed a significant reduction in mucosa thickness and tubular-to-proliferative-cell ratio, as well as an absence of hyaline secretion in the lumen. Electrodense material scattered in proventricular and gizzard cells was observed, with a structure consistent with that of coronaviruses. These pathological chicken embryo findings have not been reported as being caused by other IBV strains in Mexico.

    This study investigated the biological adaptation of loblolly pine following long-term seasonal exposure to elevated carbon dioxide (CO{sub 2}) partial pressures (pCO{sub 2}). Exposure to elevated atmospheric CO{sub 2} (pCO{sub 2}) usually results in significant stimulation in light-saturated rates of photosynthetic CO{sub 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{sub 2} at the Duke FACE site. The effect of elevated pCO{sub 2} on electron transport and energy dissipation in the pine trees was examined by coupling the analyses of the capacity for photosynthetic oxygen (O{sub 2}) evolution, chlorophyll fluorescence emission and photosynthetic pigment composition with measurements of net photosynthetic CO{sub 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{sub 2} in comparison with needles of the same age cohort in ambient pCO{sub 2}. Thus, older needles exhibited greater photosynthetic down-regulation than younger needles in elevated pCO{sub 2}. In the winter, Asat was not significantly affected by growth pCO{sub 2}. Asat was lower in winter than in summer. Growth at elevated pCO{sub 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{sub 2} on Calvin cycle activity. 73 refs., 4 figs.

    Small cell lung cancer (SCLC) is commonly classified as either limited or extensive, but the Union for International Cancer Control TNM Classification of Malignant Tumours seventh edition (2009) recommended tumor, node, and metastasis (TNM) staging based on analysis of the International Association for the Study of Lung Cancer (IASLC) database. Survival analyses were performed for clinically and pathologically staged patients presenting with SCLC from 1999 through 2010. Prognosis was compared in relation to the TNM seventh edition staging to serve as validation and analyzed in relation to proposed changes to the T descriptors found in the eighth edition. There were 5002 patients: 4848 patients with clinical and 582 with pathological stages. Among these, 428 had both. Survival differences were confirmed for T and N categories and maintained in relation to proposed revisions to T descriptors for seventh edition TNM categories and proposed changes in the eighth edition. There were also survival differences, notably at 12 months, in patients with brain-only single-site metastasis (SSM) compared to SSM at other sites, and SSM without a pleural effusion showed a better prognosis than other patients in the M1b category. We confirm the prognostic value of clinical and pathological TNM staging in patients with SCLC, and recommend continued usage for SCLC in relation to proposed changes to T, N, and M descriptors for NSCLC in the eighth edition. However, for M descriptors, it remains uncertain whether survival differences in patients with SSM in the brain simply reflect better treatment options rather than better survival based on anatomic extent of disease.

    Moore, Juanita Martin

    The purpose of this research was to examine the effects of summer science enrichment on eighth-graders' science process skills knowledge, attitude toward science and perceptions of scientists. A single group pre- and post-test design was used to test participants in a summer science enrichment camp, which took place over a three-week period in the summer of 2000. Participants, all of whom were residents of the Mississippi area known as the Delta, lived on the campus of Mississippi Valley State University for the entire course of the camp. Activities included several guided inquiry-based projects such as water rocket design and solar or battery-powered car design. Participants also took trips to an environmental camp in north Mississippi and to the Stennis Space Center on the Mississippi Gulf Coast. Participants worked on their projects in groups, supervised by an undergraduate student "mentor". Participants were encouraged to keep journals of their experiences throughout the camp, and the researcher developed a rubric to evaluate student journals for process knowledge, evidence of planning, reflective thought, and disposition toward science. Tests were used to evaluate student knowledge of process skills, attitude toward science, and perceptions of scientists. On the Test of Integrated Process Skills (Dillashaw & Okey, 1983), the students showed significant improvement overall, but when evaluated separately, males showed significant improvement while females did not. On the Attitude toward Science in School Assessment (Germane, 1988), data indicated that attitude toward science improved significantly for the group as a whole, but upon closer inspection, indicated a significant improvement for the female students only. On Chamber's Draw-a-Scientist Test (1983), analysis of student drawings indicated no significant change in stereotypical images of scientists for the group overall. However, boys' scores indicated a significant improvement when analyzed separately

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

    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 < .67). The results from this content analysis indicated little change from previous studies in the balance for the themes of the nature of science. This investigation found the sixth-grade, seventh-grade, and eighth-grade science textbooks adopted by Texas to have unbalanced presentations for the four aspects of the nature of science. In addition, it found these middle school science textbooks are not balanced across programs. This imbalance is providing

    Every three years since 1983, the paleoceanographic community has come together at a different venue to share new data and discoveries at the International Conference on Paleoceanography (ICP). For the recent ICP-8, France was the host country for a conference focused on the theme of “An Ocean View of Global Change.” The Environnements et Paleoenvironnement Oceanique (EPOC) paleoceanography group of the University Bordeaux I acted as the local organizing committee.Scientific presentations at ICP-8 addressed the latest discoveries in paleoceanography and highlighted both emerging and as-yet-unsolved questions on global climate change. Thirty-five speakers, invited by the ICP-8 Science Committee, gave overview talks during morning sessions organized around five major scientific themes. These themes were Cenozoic-Mesozoic Oceans; Carbonate and Silica Systems of the Pleistocene Ocean; Biogeochemical Cycles of the Past; High-Frequency Climate Variability; and Interhemispheric Ocean-Continent-Climate Linkages.

    Multiple guidelines and statements related to hypertension have recently been published. Much discord has arisen from discrepant treatment and target systolic blood pressure thresholds for individuals aged 60 to 79 years of Hypertension and International Society of Hypertension 2013. We sought to evaluate the public health implications of these differences using data from the 2005 to 2010 National Health and Nutrition Examination Survey (NHANES) cycles. NHANES is an ongoing survey designed to allow characterization of the US population and subpopulations. We found that only .2.4% (95% confidence interval, 1.5.3.2%) of adults aged 60 to 79 years had indications for antihypertensive treatment under the more stringent American Society of Hypertension and International Society of Hypertension 2013 guideline but not under Eighth Joint National Committee. About 65.7% (95% confidence interval, 62.4.69.0%) of adults aged 60 to 79 years had indications for treatment under both guidelines. Furthermore, those with indications for treatment under American Society of Hypertension and International Society of Hypertension 2013 but not under Eighth Joint National Committee generally had higher systolic blood pressure and less favorable lipid profiles compared with those with indications for treatment under both guidelines. Importantly, a larger group, comprising 21.0% (95% confidence interval, 18.7.23.2%) of adults aged 60 to 79 years, had either untreated or inadequately treated hypertension and represents an important group for continued efforts.

    The M component and TNM stage groupings for malignant pleural mesothelioma (MPM) have been empirical. The International Association for the Study of Lung Cancer developed a multinational database to propose evidence-based revisions for the eighth edition of the TNM classification of MPM. Data from 29 centers were submitted either electronically or by transfer of existing institutional databases. The M component as it currently stands was validated by confirming sufficient discrimination (by Kaplan-Meier analysis) with respect to overall survival (OS) between the clinical M0 (cM0) and cM1 categories. Candidate stage groups were developed by using a recursive partitioning and amalgamation algorithm applied to all cM0 cases. Of 3519 submitted cases, 2414 were analyzable and 84 were cM1 cases. Median OS for cM1 cases was 9.7 months versus 13.4 months (p = 0.0013) for the locally advanced (T4 or N3) cM0 cases, supporting inclusion of only cM1 in the stage IV group. Exploratory analyses suggest a possible difference in OS for single- versus multiple-site cM1 cases. A recursive partitioning and amalgamation-generated survival tree on the OS outcomes restricted to cM0 cases with the newly proposed (eighth edition) T and N components indicates that optimal stage groupings for the eighth edition will be as follows: stage IA (T1N0), stage IB (T2-3N0), stage II (T1-2N1), stage IIIA (T3N1), stage IIIB (T1-3N2 or any T4), and stage IV (any M1). This first evidence-based revision of the TNM classification for MPM leads to substantial changes in the T and N components and the stage groupings.

    Nizic, Bene

    1985-12-01

    This thesis consists of two unrelated topics in perturbative quantum field theory: eighth order QED contribution to the anomalous magnetic moment of the muon and next to leading order perturbative QCD correction to (gamma)(gamma) ( --->) M('+)M('-)(M = (pi),K). In Part I we present the evaluation of the complete eighth order QED contribution to the difference of the anomalous magnetic moments of the muon and the electron, (a(,(mu)) - a(,e))('(8)), arising from 469 Feynman diagrams. Our result is 140.7(4.5)((alpha)/(pi))('4). The theoretical error represents the estimated accuracy of the required numerical integration. We have also improved the light -by-light QED contribution to (a(,(mu)) - a(,e))('(6)). With these results the difference a(,(mu)) - a(,e) through eighth order in QED is (a(,(mu)) - a(,e))('QED) = 619 551(21) x 10('-11). Adding to the present theoretical value of the electron anomaly a(,e)('QED) = 115 965 246(5) x 10(' -11), we find that the pure QED contribution to the muon anomaly is given by a(,(mu))('QED) = 116 584 797(22) x 10('-11). In Part II we present the results of our calculation of the next to leading order perturbative QCD correction to the two-photon exclusive channels (gamma)(gamma)(-- ->)M('+)M('-)(M = (pi),K) at large momentum transfer. Calculation is performed in the Feynman gauge. Dimensional regularization is used to treat both UV and (//R) divergences. The meson distribution amplitude is taken to be (PHI)(,M)(PROPORTIONAL)('(delta))(x - 1/2). In order to reduce the dependence on the particular choice of (PHI)(,M), similarity of (gamma)(gamma)(--->)M('+)M(' -) and meson electromagnetic form-factor is employed. One loop correction to the (gamma)(gamma)(--->)M('+)M('-) cross section is obtained. In the MS renormalization scheme this correction is found not to be large.

    The disappearing text paradigm was used to investigate how early in a fixation the eighth graders were able to obtain sufficient information from the text to read when disappearing unit was a word. Compared with the control condition, for the mean fixation duration, the differences were apparent when words disappeared after 40ms and 60ms in the experiment. There was no significant difference between the conditions which the words disappeared after 80ms and the control condition. However no disappearing conditions interrupted the total reading time. So we concluded that for eighth-grade children, when they processed disappearing text most of the visual information necessary for reading could be acquired within the initial 50-60ms during a fixation in Chinese reading.%本研究通过消失文本实验范式,考察八年级阅读者在刺激材料以双字词为消失单元时,从视觉刺激中提取语义信息的必要呈现时间。实验发现40ms以上延迟时间的消失文本并不影响读者的总阅读时间,但在80ms消失的条件下,注视时间与控制条件下的差异不再显著。结果支持眼动控制理论中的认知控制模型。

    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 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.

  2. An evaluation of integrated curriculum as it exists in mathematics and science SSS as well as the subsequent supportive presentation of those standards in eighth grade mathematics and science textbooks

    This study attempted to verify points of intersection (POIs) between mathematics and science in the eighth grade Sunshine State Standards (SSS), and to develop a valid and reliable instrument to evaluate these POIs as they were presented in the respective mathematics and science textbooks approved for use in Florida public schools. Shannon and Weaver (1998) delineated a process for content analysis that informed the design of this analysis. The process began with an analysis of the SSS to uncover POIs between mathematics and science; considered effective strategies for presenting these points of intersection in the classroom; and examined the textbooks for a mutually supportive presentation of the POIs between the two domains. The criterion for textbook evaluation was synthesized from documents used by the National Research Council (NRC, 2004) and Project 2061 (Roseman, Kulm, Shuttleworth, 2001. These criteria were examined in terms of measureable elements of textbook design, vocabulary, inquiry and problem solving in order to create integrated objectives, which were then operationalized so that each objective could be evaluated using the Textbook Evaluation Document (TED). The validity of the TED was insured by the transparency of the process. Reliability was determined in two steps, first to determine the most reliable segments of the document and finally to confirm the reliability of those segments. It was determined that the vocabulary section of the TED consistently produced reliability scores above 70% with variation of Supportive Curriculum Scores (SCS) between textbooks. This indicated that a measure of supportive vocabulary could be generated for use in future studies for example correlating supportive curriculum with student achievement.

    This article proposes codes for the primary tumor categories of adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA) and a uniform way to measure tumor size in part-solid tumors for the eighth edition of the tumor, node, and metastasis classification of lung cancer. In 2011, new entities of AIS, MIA, and lepidic predominant adenocarcinoma were defined, and they were later incorporated into the 2015 World Health Organization classification of lung cancer. To fit these entities into the T component of the staging system, the Tis category is proposed for AIS, with Tis (AIS) specified if it is to be distinguished from squamous cell carcinoma in situ (SCIS), which is to be designated Tis (SCIS). We also propose that MIA be classified as T1mi. Furthermore, the use of the invasive size for T descriptor size follows a recommendation made in three editions of the Union for International Cancer Control tumor, node, and metastasis supplement since 2003. For tumor size, the greatest dimension should be reported both clinically and pathologically. In nonmucinous lung adenocarcinomas, the computed tomography (CT) findings of ground glass versus solid opacities tend to correspond respectively to lepidic versus invasive patterns seen pathologically. However, this correlation is not absolute; so when CT features suggest nonmucinous AIS, MIA, and lepidic predominant adenocarcinoma, the suspected diagnosis and clinical staging should be regarded as a preliminary assessment that is subject to revision after pathologic evaluation of resected specimens. The ability to predict invasive versus noninvasive size on the basis of solid versus ground glass components is not applicable to mucinous AIS, MIA, or invasive mucinous adenocarcinomas because they generally show solid nodules or consolidation on CT.

    Patients with lung cancer who harbor multiple pulmonary sites of disease have been challenging to classify; a subcommittee of the International Association for the Study of Lung Cancer Staging and Prognostic Factors Committee was charged with developing proposals for the eighth edition of the tumor, node, and metastasis (TNM) classification to address this issue. A systematic literature review and analysis of the International Association for the Study of Lung Cancer database was performed to develop proposals for revision in an iterative process involving multispecialty international input and review. Details of the evidence base are summarized in other articles. Four patterns of disease are recognized; the clinical presentation, pathologic correlates, and biologic behavior of these suggest specific applications of the TNM classification rules. First, it is proposed that second primary lung cancers be designated with a T, N, and M category for each tumor. Second, tumors with a separate tumor nodule of the same histologic type (either suspected or proved) should be classified according to the location of the separate nodule relative to the index tumor-T3 for a same-lobe, T4 for a same-side (different lobe), and M1a for an other-side location-with a single N and M category. Third, multiple tumors with prominent ground glass (imaging) or lepidic (histologic) features should be designated by the T category of the highest T lesion, the number or m in parentheses (#/m) to indicate the multiplicity, and a collective N and M category for all. Finally, it is proposed that diffuse pneumonic-type lung cancers be designated by size (or T3) if in one lobe, T4 if involving multiple same-side lobes, and M1a if involving both lungs with a single N and M category for all areas of involvement. We propose to tailor TNM classification of multiple pulmonary sites of lung cancer to reflect the unique aspects of four different patterns of presentation. We hope that this will lead to

    Problem. Increasing scientific evidence reveals that this planet is in serious environmental jeopardy. Since 1977, when an international group of K--12 educators met in the USSR and established goals for teaching environmental education worldwide, many schools have endeavored to fulfill these goals through the use of various curricula and teaching strategies. Although some progress has been made, most K--12 public schools have not done enough to meet the demands of environmental problems. In 1996, my co-teacher and I designed and implemented an environmental project, called Mission Environment, that we hoped would help our students develop long-term positive environmental attitudes and behaviors. Purpose. This study is an attempt to discover how effective the Mission Environment project (ME) was in contributing to long-term, positive environmental attitudes and behaviors among the participating students. Methodology. The study used quantitative and qualitative methods. Data were collected by surveying the members of a high-school senior class to determine their current environmental attitudes, behavior, affect, and knowledge. Of the 71 students surveyed, 28 indicated that they had been ME participants during their eighth-grade year (1996--97). The survey data were analyzed using the students' independent samples t test and chi square. Additionally, through student interviews, the study investigated the hypothesis that the teaching methods used during the course of the project contributed to producing these long-term effects. As a result of reflective interviews about the ME project and data from the literature review, a model has been created for a middle-school environmental education project in the form of an Innovation Configuration. This model is presented as part of the results of this study. Findings and conclusions. The results of the statistical analysis of the environmental survey data showed statistically significant differences between the ME

    Application of tumor, node, and metastasis (TNM) classification is difficult in patients with lung cancer presenting as multiple ground glass nodules or with diffuse pneumonic-type involvement. Clarification of how to do this is needed for the forthcoming eighth edition of TNM classification. A subcommittee of the International Association for the Study of Lung Cancer Staging and Prognostic Factors Committee conducted a systematic literature review to build an evidence base regarding such tumors. An iterative process that included an extended workgroup was used to develop proposals for TNM classification. Patients with multiple tumors with a prominent ground glass component on imaging or lepidic component on microscopy are being seen with increasing frequency. These tumors are associated with good survival after resection and a decreased propensity for nodal and extrathoracic metastases. Diffuse pneumonic-type involvement in the lung is associated with a worse prognosis, but also with a decreased propensity for nodal and distant metastases. For multifocal ground glass/lepidic tumors, we propose that the T category be determined by the highest T lesion, with either the number of tumors or m in parentheses to denote the multifocal nature, and that a single N and M category be used for all the lesions collectively-for example, T1a(3)N0M0 or T1b(m)N0M0. For diffuse pneumonic-type lung cancer we propose that the T category be designated by size (or T3) if in one lobe, as T4 if involving an ipsilateral different lobe, or as M1a if contralateral and that a single N and M category be used for all pulmonary areas of involvement.

    地震数据体结构特征,指对二维或三维地震数据体中每一地震道离散数据点按时间顺序排列所显示的波形特征.应用地震数据体结构特征法对储层进行油气预测,是近年来新兴的一项储层预测技术.塔河油田八区的主产层为碳酸盐岩裂缝-缝洞型储层,具有很强的非均质性,给储层的油气预测带来了一定的困难.针对塔河油田八区特殊的地质条件,采用了地震数据体结构特征法对该区奥陶系储层进行了油气预测,并对油区内、外的区域进行了有利区块的划分.在有利区块中设计的18口钻探井位,经钻井证实均获得了较高的油气产量,取得了很好的经济效益.%Seismic data structure characteristics means the waveform character arranged in the time sequence at discrete data points in each 2-D or 3-D seismic trace. Hydrocarbon prediction using seismic data structure characteristics is a new reservoir prediction technique.When the main pay interval is in carbonate fracture and fissure-cavern type reservoirs with very strong inhomogeneity, there are some difficulties with hydrocarbon prediction. Because of the special geological conditions of the eighth zone in the Tahe oil field, we apply seismic data structure characteristics to hydrocarbon prediction for the Ordovician reservoir in this zone. We divide the area oil zone into favorable and unfavorable blocks. Eighteen well locations were proposed in the favorable oil block, drilled, and recovered higher output of oil and gas.

    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.

    2005年直木奖获得者角田光代是日本当代重要的女作家,她的小说塑造了一种被她称为“空壳”人的类型化的人物,即没有固定职业,没有明确目标,外表漠然,内心空虚,抗拒世俗公认的价值观,在社会上缺乏存在感和自我认同。她发现了他们,试图通过他们揭开和谐社会和谐家庭的面纱,展示平静海面下的波涛汹涌,对现行的社会运行模式提出质疑。畅销小说《第八日的蝉》有迎合大众的通俗性,但并未放弃她一贯的对空壳女性的关注,并尝试给予空壳女性前所未有的温暖和救赎的希望。%Kakuta Mitstuyo is one of the most important contemporary Japanese woman writers. (She was awarded Naoki Award for literature in 2005.) Kakuta Mitsuyo has portrayed a type of characters which she refers to as the “empty-shell.” Without career, these people have no definite goals in their lives; they flatly reject the prevalent values; yet they lack the sense of being and identity. Kakuta discovered these people and attempts to uncover the veils of their harmonious families and society in order to reveal their real lives which are fraught with tensions and conflicts. The contemporary model of social operation is thus brought to question. Her best-seller The Eighth Day Cicada is undeniably pleasing. Yet her concern is still with giving the empty-shell women warmth and the hope of salvation.

    the Xinjiang oasis and desert. In the diverse natural environment, agriculture is the main stay in XPCC and the intensity of agriculture in XPCC is higher than in other areas of Xinjiang. Land use/cover types in XPCC have changed markedly with socio-economic development. The Eighth Division of XPCC was investigated in this study. Aided by field verification, the changes in land use/cover in the study region were determined in RS and GIS environments. The study used Landsat TM satellite imagery for 2000 and 2005 in combination with environment first satellite CCD imagery for 2010 to explore the dynamics of land use/cover and landscape patterns. The changes were analyzed for vegetation cover degree for different land use/cover types using MODIS data for 2000, 2005 and 2010. The results showed that:1) the study area mainly composed of cultivated land, brush land and grassland, accounting for 88.9%of the study area. The changes in land use/cover in the region were mainly driven by natural and human factors. The areas of grassland and brush land decreased respectively from 2 603.2 km2 and 1 166.2 km2 in 2000 to 1 677.3 km2 and 933.8 km2 in 2010. On the contrary, the areas of cultivated land and urban land increased respectively from 2 892.8 km2 and 209.2 km2 in 2000 to 4 038.3 km2 and 259.1 km2 in 2010. Grassland and brush land were mainly converted into cultivated land and cultivated land converted into urban land. The overall state of land use/cover change in the study area was in unbalanced. 2) An increasing simplification was noted in the characteristics of the landscape in the study area. Land use/cover change had changed regional landscape pattern in the region. Landscape pattern analysis showed obvious increasing dominance with decreasing landscape diversity and evenness. While patchy fragmentation decreased, biodiversity appeared to shift in a single direction. 3) The order of vegetation cover degree for different land use/cover types was forest land

The sandstone is lithic quartz with middle to perfect sorting and poor psephicity. Cementation is mainly of secondary enlargement-pore and a less proportion of pore cementation. The impact of strong compaction during the early diagenesis was greatest and its porosity loss-rate was 69.09%, and the porosity loss-rate of of cementation was 25.16%. The dissolution of the reservoir sandstone improved the porosity by about 5.82%, which provided the main space for the accumulation of gas reservoirs.

    Full Text Available The increasing prevalence of energy drink (ED use and its link with negative behaviors and adverse health outcomes has garnered much attention. Use of EDs combined with alcohol among college students has been of particular interest. It is unclear if these relationships develop in the context of college, or if similar associations exist in younger individuals. The present study examined associations between ED consumption patterns and other substance use in an adolescent, school-based sample. Participants were N = 3743 students attending 8th, 10th or 12th grade in a suburban central Virginia public school system who completed a prevention needs assessment survey in 2012. Chi-square analyses and logistic regressions were used to compare rates of alcohol, tobacco and other drug use across three ED use groups: moderate/heavy (12.6%, light (30.5%, and non-users (57%. Over 40% of the sample reported recent (past month ED use, with males more likely to report moderate/heavy ED use than females (14.0% and 11.1%, respectively; p = 0.02. After adjusting for gender and grade, ED use group predicted lifetime alcohol, tobacco and other drug use (all p < 0.001. Moderate/heavy ED users were most likely and ED non-users were least likely to report using each of the 13 substances in the survey, with light ED users intermediate to the other two groups. Moderate/heavy ED users were consistently most likely to report licit and illicit substance use. Additional research is needed to better understand which adolescents are at greatest risk for adverse health behaviors associated with ED use.

  17. Nondestructive evaluation techniques for high-temperature ceramic components. Eighth quarterly report, July-September 1979

    Energy Technology Data Exchange (ETDEWEB)

    1979-10-01

    Progress in research on nondestructive techniques for detecting defects in high-temperature structural ceramics is reported. These techniques include dye-enhanced radiography, acoustic microscopy, conventional ultrasonic testing, acoustic-emission detection, acoustic impact testing, holographic interferometry, infrared scanning, internal friction measurements and overload proof testing. The effect of varying microstructure on flaw detectability was demonstrated by comparing ultrasonic signal amplitudes from notches in siliconized and sintered SiC tubes. Signal amplitudes were approx. 4 dB higher in the sintered material. Knoop dents with depths as small as 25 ..mu..m, not detectable at conventional operating frequency (10 MHz), were clearly resolved by use of a 75-MHz transducer. The velocity of sound was measured as a function of the volume fraction of silicon in Carborundum KT samples. The results suggest that measurement of the velocity of sound may be adequate for indicating silicon content. Initial data have been presented on flaw detection in SiC tubing with the bore-side ultrasonic probe and acoustic microscope stage. Preliminary results were encouraging. A novel dynamic holography technique was demonstrated. A 100 x 50-mm-deep Knoop indent in a SiC bar could clearly be seen by this technique, which is a significant improvement over previous optical methods. (LCL)

    Iskenderov, G.M.

    1969-01-01

    This reservoir has been depleted since 1955 without pressure maintenance.Consequently, production has been falling rapidly and water has appeared in some of the wells. Productivity of water-invaded wells has been increased by dropping foaming agent to the well bottom. The resulting foam has dewatered the wells and thereby tripled gas production. A study was conducted to find what fraction of condensate is left in the reservoir as pressure is lowered to atmospheric. Experiment showed that 71% of the condensate did not vaporize, and therefore was left underground. It also was found that under similar depletion conditions, less condensate vaporized from the rock than from a container free of porous media.

    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.

    This fourth supplement after the 6th edition (1983) of the AOU "Check-list of North American Birds" consists of changes adopted by the Committee on Classification and Nomenclature between 1 March 1989 and 1 March 1991. The changes fall into eight categories: (1) five species (Ixobrychus sinensis, Porphyrula flavirostris, Sterna bergii, Streptopelia orientalis, and Ficedula narcissina) are added to the main list because of new distributional information; (2) six species (Pterodroma cervicalis, Ortalis wagleri, Lophornis brachylopha, Corvus sinaloae, Cinclocerthia gutturalis, and Loxops caeruleirostris) are added to the list because of the splitting of species previously in the list; (3) one extinct species (Dysmorodrepanis munroi) is added to the list because of re-identification of the unique type; (4) one scientific name (Speotyto cunicularia) is changed because of generic splitting; (5) one scientific name (Phalacrocorax brasilianus) is changed for nomenclature reasons, accompanied by a change in English name; (6) the spelling of one scientific name (Neocrex colombianus) is corrected; (7) to other English names are changed or corrected; and (8) one sequencing change is made. No new distributional information is included except as noted above (i.e. minor changes of distribution of distributional records within North America are not included). The twelve additions bring the number of species recognized as occurring within the Check-list area (main list) to 1957.

    Shwalb, D; Shwalb, B; Murata, K

    1989-01-01

    The study compared the expression of cooperation, competition, individualism and interpersonalism in Japanese youth. Forty-two 5th grade boys and 42 8th grade boys first completed two questionnaires about cooperation/competition and group/individualized activities. Their group structure was then coded (as working in trios, in duos, or separately) as trios of boys built houses with playing cards. The experimental design crossed instructions (1) to work individually or in a group and (2) compete or do one s own best. Subjects were questioned about their awareness of, liking for and prefercnces for the cooperative, individualistic, and group-centered aspects of the experimental tasks. On orientation scales, 8th graders chose equal numbers of individualistic and group-centered activities, while 5th graders chose more group activities. Both age groups strongly favored cooperative over competitive items. In group trials of the experiment, 8th graders tended to work alone for greater proportions of time than did 5th graders. Questionnaire data indicated that (1) 8th graders reponed greater enjoyment of the individualistic aspect of the task than did 5th graders, (2) both age groups evidenced a strong sense of interpersonalism, and (3) cooperation was rated more positively than competition at both ages. The study was discussed in relation to recent studies on Japanes school socialization and cooperation/competition.

  3. EIGHTH INTERIM STATUS REPORT: MODEL 9975 PCV O-RING FIXTURE LONG-TERM LEAK PERFORMANCE

    Energy Technology Data Exchange (ETDEWEB)

    Daugherty, W. L.

    2013-09-03

    A series of experiments to monitor the aging performance of Viton® GLT O-rings used in the Model 9975 package has been ongoing since 2004 at the Savannah River National Laboratory. Seventy tests using mock-ups of 9975 Primary Containment Vessels (PCVs) were assembled and heated to temperatures ranging from 200 to 450 ºF. They were leak-tested initially and have been tested periodically to determine if they meet the criterion of leak-tightness defined in ANSI standard N14.5-97. Fourteen additional tests were initiated in 2008 with GLT-S O-rings heated to temperatures ranging from 200 to 400 ºF. High temperature aging continues for 23 GLT O-ring fixtures at 200 – 270 ºF. Room temperature leak test failures have been experienced in all of the GLT O-ring fixtures aging at 350 ºF and higher temperatures, and in 8 fixtures aging at 300 ºF. The remaining GLT O-ring fixtures aging at 300 ºF have been retired from testing following more than 5 years at temperature without failure. No failures have yet been observed in GLT O-ring fixtures aging at 200 ºF for 61 - 85 months, which is still bounding to O-ring temperatures during storage in KArea Complex (KAC). Based on expectations that the fixtures aging at 200 ºF will remain leaktight for a significant period yet to come, 2 additional fixtures began aging in 2011 at an intermediate temperature of 270 ºF, with hopes that they may reach a failure condition before the 200 ºF fixtures. High temperature aging continues for 6 GLT-S O-ring fixtures at 200 – 300 ºF. Room temperature leak test failures have been experienced in all 8 of the GLT-S O-ring fixtures aging at 350 and 400 ºF. No failures have yet been observed in GLT-S O-ring fixtures aging at 200 - 300 ºF for 41 - 45 months. Aging and periodic leak testing will continue for the remaining PCV fixtures.

  19. 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.

    2016-01-01

    Full Text Available In this paper, we present a family of three-point with eight-order convergence methods for finding the simple roots of nonlinear equations by suitable approximations and weight function based on Maheshwari’s method. Per iteration this method requires three evaluations of the function and one evaluation of its first derivative. These class of methods have the efficiency index equal to 814≈1.682${8^{{\\textstyle{1 \\over 4}}}} \\approx 1.682$. We describe the analysis of the proposed methods along with numerical experiments including comparison with the existing methods. Moreover, the attraction basins of the proposed methods are shown with some comparisons to the other existing methods.

    Thomas, M.L. [Nuclear Regulatory Commission, Washington, DC (United States). Div. of Regulatory Applications; Hagemeyer, D. [Science Applications International Corp., Oak Ridge, TN (United States)

    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).

    Continuing the project described by Kato et al. (2009, arXiv:0905.1757), we collected times of superhump maxima for 128 SU UMa-type dwarf novae observed mainly during the 2015-2016 season and characterized these objects. The data have improved the distribution of orbital periods, the relation between the orbital period and the variation of superhumps, the relation between period variations and the rebrightening type in WZ Sge-type objects. Coupled with new measurements of mass ratios using growing stages of superhumps, we now have a clearer and statistically greatly improved evolutionary path near the terminal stage of evolution of cataclysmic variables. Three objects (V452 Cas, KK Tel, ASASSN-15cl) appear to have slowly growing superhumps, which is proposed to reflect the slow growth of the 3:1 resonance near the stability border.

    1999-09-01

    Ticks (Ixodidae) play a significant role as vectors of pathogens of domestic animals in Tunisia. The major losses caused by ticks are related to transmission of protozoan parasites. These include agents of tropical theileriosis and babesiosis in ruminants. Since 1991, we conducted research studies on tick population of livestock in Tunisia. This overview reports a synthesis on tick distribution, their biology and their role as vectors of pathogens in domestic animals, particularly cattle. During the whole period of the study about 15,000 tick specimens were collected from different zones of the country. A total of 14 species were identified. Hyalomma detritum detritum was the most abundant and important (vector of Theileria annulata) species infesting cattle. Hyalomma dromedarii and Hyalomma impeltatum were collected on domestic ruminants in the arid and desertic zones. Hyalomma marginatum marginatum and Hyalomma anatolicum excavatum were widespread and found on livestock hosts. Ixodes ricinus, vector of Babesia divergens and Borrelia burgdorferi sl, colonises mainly the humid zone. Boophilus annulatus and Rhipicephalus bursa infesting cattle, sheep and goats were found in the sub-humid and semi-arid zones. Haemaphysalis sulcata and Hae. punctata were collected in humid and sub-humid zones on cattle and sheep. Rhipicephalus turanicus were collected in different regions, on different animal species. Rhipicephalus sanguineus, tick of dogs, were often collected on livestock. Only few specimens of Hyalomma marginatum rufipes and Hyalomma franchinii were collected.

  20. What is technology? A study of fifth and eighth grade student ideas about the Nature of Technology

    Science.gov (United States)

    Digironimo, Nicole

    Most, if not all, standards for science and technology education and curriculum indicate that knowledge of the Nature of Technology is an educational goal, yet the literature lacks an established definition for the Nature of Technology. Additionally, the research on student ideas about the Nature of Technology is insufficient. After reviewing the literature on science and technology education, the philosophy of technology, and the history of technology, this study presents an internally consistent definition for the Nature of Technology. This definition illustrates how the Nature of Technology includes five dimensions: Technology as Artifacts; Technology as a Creation Process; Technology as a Human Practice; The History of Technology; and The Current Role of Technology. Using an interview protocol developed for this study, a small group of 5th and 8th grade students were interviewed to ascertain their ideas about the Nature of Technology. The results indicate that there are a variety of ideas present in the thinking of young people. All of the participants expressed one of two ideas about technological artifacts: technological artifacts are electronic or technological artifacts are invented. All of the participants identified particular skills needed to invent technological artifacts; some of the participants included mobility and concluded that disabled people cannot be inventors. Despite their experiences with technological artifacts (including educational technology tools), a few of the participants were uncertain whether they would identify themselves as technological. More than half of the participants did not believe older artifacts can still be considered technology. Most of the participants were apprehensive about our technological future; the main issue expressed by the participants was the environment. Other than environmental concerns, most of the participants were unable to identify global issues regarding technological use and development. Overall, these findings increase our knowledge of the ideas young people have about the Nature of Technology, which can inform future research on teaching and learning about science and technology.

  5. 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.

ASASSN-15cy has a short (˜0.050 d) superhump period and appears to belong to EI Psc-type objects with compact secondaries having an evolved core. ASASSN-15gn, ASASSN-15hn, ASASSN-15kh, and ASASSN-16bu are candidate period bouncers with superhump periods longer than 0.06 d. We have newly obtained superhump periods for 79 objects and 13 orbital periods, including periods from early superhumps. In order that future observations will be more astrophysically beneficial and rewarding to observers, we propose guidelines on how to organize observations of various superoutbursts.

  8. 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.

  13. Differences in eighth grade science student and teacher perceptions of students' level of input into academic planning and decision making

    Science.gov (United States)

    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.

  20. Kinetics and mechanism of desulfurization and denitrogenation of coal-derived liquids. Eighth quarterly report, March 21--June 20, 1977

    1977-08-25

    Three high-pressure flow microreactors and two batch autoclave reactors have been used to study the reaction networks and kinetics of (1) catalytic hydrodesulfurization of dibenzothiophene and methyl-substituted dibenzothiophenes and (2) catalytic hydrodenitrogenation of quinoline, methyl-substituted quinolines, and carbazole. At the typical conditions of 300/sup 0/C and 104 atm, dibenzothiophene reacts to give H/sub 2/S and biphenyl in high yield, but there is some hydrogenation preceding desulfurization. Methyl-substituted dibenzothiophenes react similarly, and each reaction is first-order in the sulfur-containing compound. Two methyl groups near the sulfur atom (in the 4 and 6 positions) reduce the reactivity tenfold, whereas methyl groups in positions further removed from the sulfur atom increase reactivity about twofold. The results are consistent with steric and inductive effects influencing adsorption. The data indicate competitive adsorption among the sulfur-containing compounds. In quinoline hydrodenitrogenation, both rings are saturated before the C-N bond is broken. Similarly, in acridine conversion, a large amount of hydrogenation precedes nitrogen removal. Breaking of the carbon-nitrogen bond is evidently one of the slower reactions in the network. The Ni-Mo catalyst is about twice as active as the Co-Mo catalyst for ring hydrogenation, and the two catalysts are about equally active for breaking the carbon-nitrogen bond. Reactivity of carbazole is similar to that of quinoline and lower than that of acridine. Again, extensive hydrogenation precedes heteratom removal.

  2. 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.

    The new 8th edition of the Union for International Cancer Control (UICC) classification of TNM staging includes relevant changes for pancreatic cancer (PC). We report on the survival stratification of the new T and N stages. The 8th edition TNM system was retrospectively applied to patients who underwent curative PC resection at our institution between 2005-2015. Some 256 patients were included. The postoperative TNM stage was pT3 in 96% of the cases according to the 7th edition of UICC staging. When the 8th edition system -which stratifies by tumor size and number of involved lymph nodes- was applied, both T- and N-stage were significant prognostic survival factors. Most interestingly, the old pT3 subgroup was split into four different pT stages of the 8th edition system with the most frequent stage being pT2 (58.6%). In this subgroup, patients with pT1-2 and pT3 tumors had a significantly different survival (P = 0.0474). Compared with the 7th edition of UICC TNM staging, the new N, but also the T system can better discriminate the overall survival of PC patients.

  18. Development of a video-based slurry sensor for on-line ash analysis. Eighth quarterly technical progress report, July 1, 1996--September 30, 1996

    Energy Technology Data Exchange (ETDEWEB)

    Adel, G.T.; Luttrell, G.H.

    1996-10-22

    Automatic control of fine coal cleaning circuits has traditionally been limited by the lack of sensors for on-line ash analysis. Although several nuclear-based analyzers are available, none have seen widespread acceptance. This is largely due to the fact that nuclear sensors are expensive and tend to be influenced by changes in seam type and pyrite content. Recently, researchers at VPI&SU have developed an optical sensor for phosphate analysis. The sensor uses image processing technology to analyze video images of phosphate ore. It is currently being used by PCS Phosphate for off-fine analysis of dry flotation concentrate. The primary advantages of optical sensors over nuclear sensors are that they are significantly cheaper, are not subject to measurement variations due to changes in high atomic number minerals, are inherently safer and require no special radiation permitting. The purpose of this work is to apply the knowledge gained in the development of an optical phosphate analyzer to the development of an on-fine ash analyzer for fine coal slurries. During the past quarter, installation of the video-based ash analyzer at the Middle Fork plant site was completed. A method of measuring and automatically adjusting for small variations in the sensor illumination scheme was developed and implemented. Initial on-line testing of the ash analyzer has yielded adequate calibration information, and the sensor is currently operating on-line. The on-line performance of the sensor is under review and the information from this review will be included in the final report.

    2017-02-25

    TNM staging is essential for clinical decision-making and prognostic prediction for patients with gastric cancer. The 7th TNM staging manual was formulated in 2009 and implemented in 2010. However, it was published that there were some deficiencies of the 7th edition of gastric cancer TNM staging system in clinical application process, and this old staging system could not meet the clinical needs. With the cooperation and promotion of the American Joint Committee on Cancer (AJCC), the International Union for Cancer Control (UICC) and the International Gastric Cancer Association (IGCA), and through the accumulation and analysis of gastric cancer big data, the 8th TNM staging system was published at the end of 2016. The updated staging system has defined the selection of staging system for esophagogastric junction cancer. It also has divided N3 into N3a and N3b, which has been incorporated into the new staging system, leading to more accurate risk stratification. Moreover, the cTNM staging system and ypTNM staging system have been added in the new staging manual. Overall, the 8th TNM staging system can facilitate more reasonable decision-making, more accurate prognostic prediction and better evaluation of therapeutic strategy. It is of high value to promote diagnostic and therapeutic standard for gastric cancer.

    The objective of Phase II of this program is to investigate the effects of various processes, metal contaminants, and contaminant-process interactions on the performance of terrestrial silicon solar cells so that purity requirements for a solar grade silicon can be delineated. The program approach consists in (1) the growth of doubly and multiply-doped silicon single crystals containing a baseline boron or phosphorus dopant and specific impurities which produce deep levels in the forbidden band gap, (2) assessment of these crystals by a battery of chemical, microstructural, electrical and solar cell tests, (3) correlation of the impurity kind and level with crystal quality and device performance, (4) delineation of the role of impurities and processing on subsequent silicon solar cell performance, and (5) determination of the combined effects of impurities and growth rate on the crystal quality and cell performance of silicon produced by both the dendritic web and Czochralski methods. The central thrust of activities this quarter was in three areas: the crystal growth of impurity-bearing ingots with different base doping types and concentrations; evaluation of the solar cell performance of n-base and p-base devices; and refinement of techniques for the analysis of solar cells subjected to various contaminants and process variations.

    1978-04-03

    To meet the goals of the LSSA program, solar cell encapsulants must provide protection for 20 years. Consequently, the objective of the present program is to develop methodology for making confident predictions of encapsulant performance at any exposure site in the U.S.A. During the first year of the program, inherent weatherability was studied. Inherent weatherability is controlled by the three weather factors common to all exposure sites: insolation, temperature, and humidity. Emphasis was focused on the transparent encapsulant portion of miniature solar cell arrays by eliminating weathering effects on the substrate and circuitry (which are also parts of the encapsulant system). The most extensive data were for yellowing, which was measured conviently and precisely. Considerable data also were obtained on tensile strength. Changes in these two properties after outdoor exposure were predicted very well from accelerated exposure data. Although more outdoor exposure data will be received, mathematical modeling studies are continuing. This first part of the program can be said to be successfully concluded. In continuation of the inherent weatherability study, the power output of solar cells was monitored under accelerated test conditions and is being followed for outdoor exposures. For this purpose, Universal Test Specimens (UTS's) with nine different substrate/transparent encapsulant combinations were prepared. Again, the objective is to predict outdoor performance from accelerated exposure data with photochemical stresses of about 8 times normal. Continuous accelerated exposure under 8 key combinations of ultraviolet (UV) light intensity, temperature, and humidity was continued for 2 months. Then the same UTS's were exposed to 100% relative humidity at 100/sup 0/C for one month. Degradation effects are discussed and illustrated.

    1994-01-31

    The primary objective of the present Phase 3 effort is to perform the final testing at a 20 MMBtu/hr commercial scale of an air cooled, slagging coal combustor for application to industrial steam boilers and power plants. The focus of the test effort will be on combustor durability, automatic control of the combustor`s operation, and optimum environmental control of emissions inside the combustor. In connection with the latter, the goal is to achieve 0.4 lb/MMBtu of SO{sub 2} emissions, 0.2 lb/MMBtu of NO{sub x} emissions, and 0.02 lb particulates/MMBtu. Meeting the particulate goal will require the use of a baghouse or electrostatic precipitator to augment the nominal slag retention in the combustor. The NO{sub x} emission goal will require a modest improvement over maximum reduction achieved to date in the combustor to a level of 0.26 lb/MMBtu. To reach the SO{sub 2} emissions goal may require a combination of sorbent injection inside the combustor and sorbent injection inside the boiler, especially in high (>3.5%) sulfur coals. Prior to the initiation of the project, SO{sub 2} levels as low as 0.6 lb/MMBtu, equal to 81% reduction in 2% sulfur coals, were measured with boiler injection of calcium hydrate. The final objective is to define suitable commercial power or steam generating systems to which the use of the air cooled combustor offers significant technical and economic benefits. In implementing this objective both simple steam generation and combined gas turbine-steam generation systems will be considered.

  6. 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.

  8. 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.

  12. 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.

    Weber, C.M.

    1979-01-01

    Objective is to develop and demonstrate an electron beam welding procedure for welding 8-inch thick SA 387 Grade 22 Class (2-1/4 Cr-1 Mo) steel. A total of 469 experimental welds have been made to date. Efforts to develop welding procedures which produce defect-free welds have been successfully completed. Techniques for acceptably starting and stopping electron beam welds were developed. Work on developing an EB repair technique is in progress. It has been learned that re-welding of holes, without metal additions, is unacceptable. Work to define the joint fit-up requirements is nearly complete. A considerable amount of joint mismatch can be readily welded and a joint gap opening in excess of 0.100 inch can be welded without alteration of the welding procedure. Another large test plate was welded using equipment with a modified drive. The weld was unacceptable due to porosity. It appears that poor base metal quality is adversely affecting weld quality. Specimens for testing the as-welded mechanical properties have been machined and are being tested.
