Exact Solutions for the Integrable Sixth-Order Drinfeld-Sokolov-Satsuma-Hirota System by the Analytical Methods.

PubMed

Manafian Heris, Jalil; Lakestani, Mehrdad

2014-01-01

We establish exact solutions including periodic wave and solitary wave solutions for the integrable sixth-order Drinfeld-Sokolov-Satsuma-Hirota system. We employ this system by using a generalized (G'/G)-expansion and the generalized tanh-coth methods. These methods are developed for searching exact travelling wave solutions of nonlinear partial differential equations. It is shown that these methods, with the help of symbolic computation, provide a straightforward and powerful mathematical tool for solving nonlinear partial differential equations.

Objective: The aim of this investigation was to test hypothesized reverse prospective relationships between alcohol consumption and depressive symptomatology as a function of race among youth. Method: In a two-wave prospective study, 328 European American, 328 African American, and 144 Hispanic American youth were studied at the end of fifth grade (last year of elementary school) and the end of sixth grade (first year of middle school). Results: A positive correlation was observed between alcohol consumption and depressive symptoms among all youth. However, the predictive relationship differed based on race. For European American and Hispanic American youth, depressive symptom levels at the end of elementary school predicted alcohol consumption at the end of the first year of middle school, but the converse relationship was not observed. For African American youth, the opposite pattern was found. Alcohol consumption at the end of elementary school predicted depressive symptom levels at the end of the first year of middle school, and the converse relationship was not observed. Conclusions: These findings suggest the possibility that etiological relationships between depression and alcohol use vary by race, thus highlighting the importance of considering race when studying the risk process.

Numerical solution of sixth-order boundary-value problems using Legendre wavelet collocation method

NASA Astrophysics Data System (ADS)

Sohaib, Muhammad; Haq, Sirajul; Mukhtar, Safyan; Khan, Imad

2018-03-01

An efficient method is proposed to approximate sixth order boundary value problems. The proposed method is based on Legendre wavelet in which Legendre polynomial is used. The mechanism of the method is to use collocation points that converts the differential equation into a system of algebraic equations. For validation two test problems are discussed. The results obtained from proposed method are quite accurate, also close to exact solution, and other different methods. The proposed method is computationally more effective and leads to more accurate results as compared to other methods from literature.

Raising voices: How sixth graders construct authority and knowledge in argumentative essays

NASA Astrophysics Data System (ADS)

Monahan, Mary Elizabeth

This qualitative classroom-based study documents one teacher-researcher's response to the "voice" debate in composition studies and to the opposing views expressed by Elbow and Bartholomae. The author uses Bakhtin's principle of dialogism, Hymes's theory of communicative competence, as well as Ivanic's discussion of discoursally constructed identities to reconceptualize voice and to redesign writing instruction in her sixth grade classroom. This study shows how students, by redefining and then acting on that voice pedagogy in terms that made sense to them, shaped the author's understanding of what counts as "voiced" writing in non-narrative discourse. Based on a grounded-theory analysis of the twenty-six sixth graders' argumentative essays in science, the author explains voice, not as a property of writers or of texts, but as a process of "knowing together"---a collaborative, but not entirely congenial, exercise of establishing one's authority by talking with, against, and through other voices on the issue. As the results of this study show, the students' "I-Ness" or authorial presence within their texts, was born in a nexus of relationships with "rivals," "allies" and "readers." Given their teacher's injunctions to project confidence and authority in argumentative writing, the students assumed fairly adversarial stances toward these conversational partners throughout their essays. Exaggerating the terms for voiced writing built into the curriculum, the sixth graders produced essays that read more like caricatures than examples of argumentation. Their displays of rhetorical bravado and intellectual aggressiveness, however offsetting to the reader, still enabled these sixth graders to composed voiced essays. This study raises doubts about the value of urging students to sound like their "true selves" or to adopt the formal registers of academe. Students, it seems clear, stand to gain by experimenting with a range of textual identities. The author suggests that voice, as a dialogic process, involves a struggle for meaning---in concert, but also very much in conflict with---other speakers and their intentions.

Conversion Disorder; an Unusual Etiology of Unilateral Foot Drop.

Ayaz, Saeed Bin; Matee, Sumeera; Malik, Riffat; Ahmad, Khalil

2015-06-01

Foot drop is generally a consequence of common peroneal or sciatic nerve injury or L5 radiculopathy but rarely, it can be a manifestation of conversion disorder. A 24-year-old male presented with a foot drop on left side that developed overnight. He had difficulty walking with a trunk tilt towards right side and numbness in left leg up to mid-thigh. The initial diagnosis by the general practitioner was common peroneal nerve injury, which was not supported by the subsequent detailed examination in the physiatry department. Routine laboratory investigations, computed tomographic scan of brain and electrophysiological evaluation were normal. In a multidisciplinary team evaluation involving a psychiatrist, he was diagnosed to be suffering from conversion disorder and was advised gait retraining, cognitive and behavioral therapy and tablet venlafaxine. By sixth day of treatment, the patient was able to walk independently with a normal gait pattern and reported complete recovery of his symptoms. In the absence of an identifiable organic cause of foot drop in a patient, conversion disorder may be considered necessitating early intervention by a psychiatrist.

DeVita, Stefanie F.; Vranesich, Patricia A.; Boulton, Matthew L.

2014-01-01

Objectives. We examined the effect of Michigan’s new school rules and vaccine coadministration on time to completion of all the school-required vaccine series, the individual adolescent vaccines newly required for sixth grade in 2010, and initiation of the human papillomavirus (HPV) vaccine series, which was recommended but not required for girls. Methods. Data were derived from the Michigan Care Improvement Registry, a statewide Immunization Information System. We assessed the immunization status of Michigan children enrolled in sixth grade in 2009 or 2010. We used univariable and multivariable Cox regression models to identify significant associations between each factor and school completeness. Results. Enrollment in sixth grade in 2010 and coadministration of adolescent vaccines at the first adolescent visit were significantly associated with completion of the vaccines required for Michigan’s sixth graders. Children enrolled in sixth grade in 2010 had higher coverage with the newly required adolescent vaccines by age 13 years than did sixth graders in 2009, but there was little difference in the rate of HPV vaccine initiation among girls. Conclusions. Education and outreach efforts, particularly regarding the importance and benefits of coadministration of all recommended vaccines in adolescents, should be directed toward health care providers, parents, and adolescents.

Association between the accessibility to lethal methods and method-specific suicide rates: An ecological study in Taiwan.

PubMed

Lin, Jin-Jia; Lu, Tsung-Hsueh

2006-07-01

To examine the association between availability of lethal methods of suicide and method-specific suicide rates at the city/ county level in Taiwan. Age-adjusted and age-specific suicide rates of 23 cities/counties in Taiwan for the years 1999 to 2003 were calculated. Partial correlation coefficients were used to examine cross-sectional associations between independent variables, i.e., proportion of agricultural population and proportion of households living on the sixth floor or above, and suicide rates by different methods (poisoning by solids/liquids, jumping, and hanging) after adjusting for unemployment rates and prevalence of depression. The partial correlation coefficient was 0.77 (p < .001) for proportion of agricultural population with solids/liquids poisoning suicide rates. It was 0.73 (p < .001) for the proportion of households living on the sixth floor or above with suicide rates by jumping. Correlations between hanging suicide rates and proportion of agricultural population or between hanging suicide rates and proportion of households living on the sixth floor or above were not significant. The results showed strong positive associations between access to lethal methods and method-specific suicide rates. Controlling the availability of pesticides and fencing high buildings or installing window guards may be effective measures for suicide prevention.

Structural connectivity at a national scale: Wildlife corridors in Tanzania.

PubMed

Riggio, Jason; Caro, Tim

2017-01-01

Wildlife corridors can help maintain landscape connectivity but novel methods must be developed to assess regional structural connectivity quickly and cheaply so as to determine where expensive and time-consuming surveys of functional connectivity should occur. We use least-cost methods, the most accurate and up-to-date land conversion dataset for East Africa, and interview data on wildlife corridors, to develop a single, consistent methodology to systematically assess wildlife corridors at a national scale using Tanzania as a case study. Our research aimed to answer the following questions; (i) which corridors may still remain open (i.e. structurally connected) at a national scale, (ii) which have been potentially severed by anthropogenic land conversion (e.g., agriculture and settlements), (iii) where are other remaining potential wildlife corridors located, and (iv) which protected areas with lower forms of protection (e.g., Forest Reserves and Wildlife Management Areas) may act as stepping-stones linking more than one National Park and/or Game Reserve. We identify a total of 52 structural connections between protected areas that are potentially open to wildlife movement, and in so doing add 23 to those initially identified by other methods in Tanzanian Government reports. We find that the vast majority of corridors noted in earlier reports as "likely to be severed" have actually not been cut structurally (21 of 24). Nonetheless, nearly a sixth of all the wildlife corridors identified in Tanzania in 2009 have potentially been separated by land conversion, and a third now pass across lands likely to be converted to human use in the near future. Our study uncovers two reserves with lower forms of protection (Uvinza Forest Reserve in the west and Wami-Mbiki Wildlife Management Area in the east) that act as apparently crucial stepping-stones between National Parks and/or Game Reserves and therefore require far more serious conservation support. Methods used in this study are readily applicable to other nations lacking detailed data on wildlife movements and plagued by inaccurate land cover datasets. Our results are the first step in identifying wildlife corridors at a regional scale and provide a springboard for ground-based follow-up conservation.

We propose a family of conservative finite difference schemes for the Boussinesq equation with sixth order dispersion terms. The schemes are of second order of approximation. The method is conditionally stable with a mild restriction τ = O(h) on the step sizes. Numerical tests are performed for quadratic and cubic nonlinearities. The numerical experiments show second order of convergence of the discrete solution to the exact one.

The laterally coupled distributed feedback (LC-DFB) GaSb-based type-I quantum well cascade diode lasers using the second- and the sixth-order gratings to stabilize the output spectrum near 3.22 μm were designed and fabricated. The laser heterostructure contained three cascades. The devices were manufactured using a single dry etching step defining the ∼5-μm-wide ridge with ∼5-μm-wide gratings sections adjacent to the ridge sides. The grating coupling coefficients were estimated to be about 1  cm -1 . The stability of the single-frequency operation was ensured by alignment of the DFB mode to the relatively wide gain peak. The 2-mm-long second-order LC-DFB lasers generated above 10 mW of continuous-wave (CW) output power at 20°C in epi-side-up configuration and demonstrated power conversion efficiency above 2%. The sixth-order LC-DFB lasers showed lower efficiency but still generated several milliwatts of CW output power. The devices demonstrated a CW current tuning range of about 3.5 nm at the temperature of 20°C.

2010-12-01

AMA's Guides to the Evaluation of Permanent Impairment is used to rate loss of function and determine compensation and ability to work after injury or illness; however, there are few studies that evaluate reliability or construct validity. To evaluate the reliability of the fifth and sixth editions for back injury; to determine best methods for further study. Intra-class correlation coefficients within and between raters were relatively high. There was wider variability for individual cases. Impairment ratings were lower and correlated less well for the sixth edition, though confidence intervals overlapped. The sixth edition may not be an improvement over the fifth. A research agenda should include investigations of reliability and construct validity for different body sites and organ systems along the entire rating scale and among different categories of raters.

Hilbert's sixth problem: between the foundations of geometry and the axiomatization of physics.

PubMed

Corry, Leo

2018-04-28

The sixth of Hilbert's famous 1900 list of 23 problems was a programmatic call for the axiomatization of the physical sciences. It was naturally and organically rooted at the core of Hilbert's conception of what axiomatization is all about. In fact, the axiomatic method which he applied at the turn of the twentieth century in his famous work on the foundations of geometry originated in a preoccupation with foundational questions related with empirical science in general. Indeed, far from a purely formal conception, Hilbert counted geometry among the sciences with strong empirical content, closely related to other branches of physics and deserving a treatment similar to that reserved for the latter. In this treatment, the axiomatization project was meant to play, in his view, a crucial role. Curiously, and contrary to a once-prevalent view, from all the problems in the list, the sixth is the only one that continually engaged Hilbet's efforts over a very long period of time, at least between 1894 and 1932.This article is part of the theme issue 'Hilbert's sixth problem'. © 2018 The Author(s).

We extend the numerical pole field solver (Fornberg and Weideman (2011) [12]) to enable the computation of the multivalued Painlevé transcendents, which are the solutions to the third, fifth and sixth Painlevé equations, on their Riemann surfaces. We display, for the first time, solutions to these equations on multiple Riemann sheets. We also provide numerical evidence for the existence of solutions to the sixth Painlevé equation that have pole-free sectors, known as tronquée solutions.

Examining the sustainability of Screening for Distress, the sixth vital sign, in two outpatient oncology clinics: A mixed-methods study.

2018-01-01

Research indicates that cancer patients experience significant multifactorial distress during their journey. To address this, cancer centers are implementing Screening for Distress programs; however, little is known about the sustainability of these programs. This study sought to examine the sustainability of a Screening for Distress program in 2 cancer clinics 6 months post implementation. A mixed-methods cross-sectional design was utilized. To determine if screening rates, screening conversations and appropriate interventions occurred and the charts of 184 consecutive patients attending the head and neck or neuro-oncology clinics over a 3 week period were reviewed. To examine the barriers and facilitators of sustainability, 16 semi-structured interviews with administrators, physicians, and nurses were conducted. Of the 184 charts reviewed, 163 (88.6%) had completed screening tools. Of these 163, 130 (79.8%) indicated that a conversation occurred with the patient about the identified distress as reported on the screening tool. Of the 89 (54.6%) charts where the need for an intervention was indicated, 68 (76.4%) had an intervention documented. Six oncologists, 7 nurses, and 3 administrators were interviewed, and 5 themes which influenced the sustainability of the program emerged: (1) attitudes, knowledge, and beliefs about the program; (2) implementation approach; (3) outcome expectancy of providers; (4) integration with existing practices; and (5) external factors. This study suggests that Screening for Distress was largely sustained, possibly due to positive attitudes and outcome expectancy. However, sustainability may be enhanced by formally integrating screening with existing practices, addressing potential knowledge gaps, and ensuring engagement with all stakeholder groups.

The Sixth Copper Mountain Conference on Multigrid Methods was held on April 4-9, 1993, at Copper Mountain, Colorado. This book is a collection of many of the papers presented at the conference and so represents the conference proceedings. NASA Langley graciously provided printing of this document so that all of the papers could be presented in a single forum. Each paper was reviewed by a member of the conference organizing committee under the coordination of the editors. The multigrid discipline continues to expand and mature, as is evident from these proceedings. The vibrancy in this field is amply expressed in these important papers, and the collection clearly shows its rapid trend to further diversity and depth.

From Hahnemann's hand to your computer screen: building a digital homeopathy collection

PubMed Central

Mix, Lisa A; Cameron, Kathleen

2011-01-01

The University of California, San Francisco (UCSF), Library holds the unique manuscript of the sixth edition of Samuel Hahnemann's Organon der Heilkunst, the primary text of homeopathy. The manuscript volume is Hahnemann's own copy of the fifth edition of the Organon with his notes for the sixth edition, handwritten throughout the volume. There is a high level of interest in the Organon manuscript, particularly among homeopaths. This led to the decision to present a digital surrogate on the web to make it accessible to a wider audience. Digitizing Hahnemann's manuscript and determining the best method of presentation on the web posed several challenges. Lessons learned in the course of this project will inform future digital projects. This article discusses the historical significance of the sixth edition of Hahnemann's Organon, its context in UCSF's homeopathy collections, and the specifics of developing the online homeopathy collection.

Lu, Lijun; Cao, Yiqing

2017-10-20

In this paper, we develop sixth-order wave aberration theory of ultrawide-angle optical systems like fisheye lenses. Based on the concept and approach to develop wave aberration theory of plane-symmetric optical systems, we first derive the sixth-order intrinsic wave aberrations and the fifth-order ray aberrations; second, we present a method to calculate the pupil aberration of such kind of optical systems to develop the extrinsic aberrations; third, the relation of aperture-ray coordinates between adjacent optical surfaces is fitted with the second-order polynomial to improve the calculation accuracy of the wave aberrations of a fisheye lens with a large acceptance aperture. Finally, the resultant aberration expressions are applied to calculate the aberrations of two design examples of fisheye lenses; the calculation results are compared with the ray-tracing ones with Zemax software to validate the aberration expressions.

Abstract Nutritional performance and activity of some digestive enzymes (protease and α -amylase) of Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) in response to feeding on bean ( Phaseolus vulgaris L. (Fabales: Fabaceae)) cultivars (Shokufa, Akhtar, Sayyad, Naz, Pak, Daneshkadeh, and Talash) were evaluated under laboratory conditions (25 ± 1°C, 65 ± 5% RH, and a 16:8 L:D photoperiod). The highest and lowest respective values of approximate digestibility were observed when fourth, fifth, and sixth larval instar H. armigera were fed red kidney bean Akhtar and white kidney bean Daneshkadeh. The efficiency of conversion of ingested and digested food was highest when H. armigera was fed red kidney beans Akhtar and Naz and lowest when they were fed white kidney bean Pak. The highest protease activity of fifth instars was observed when they were fed red kidney bean Naz, and the highest amylase activity of fifth instars was observed when they were fed red kidney bean Sayyad. Sixth instar larvae that fed on red kidney bean Sayyad showed the highest protease activity. Larvae reared on common bean Talash and white kidney bean Pak showed the highest amylase activity. Among bean cultivars tested, red kidney bean Sayyad was the most unsuitable host for feeding H. armigera . PMID:25368049

Objective: This article examines the association between fathers’ alcohol problems and children’s effortful control during the transition from middle childhood to early adolescence (fourth to sixth grade). Additionally, we examined the role of two potential moderators of this association, fathers’ antisocial behavior and child gender. Method: The sample consisted of 197 families (102 nonalcoholic [NA]; 95 father alcoholic [FA], in which only the father met diagnostic criteria for alcohol abuse or dependence). The sample was recruited from New York State birth records when the children were 12 months old. This analysis focused on 12-month alcohol problem data and child effortful control data measured in the fourth and sixth grades. Results: Structural equation modeling revealed that FA status was associated with lower effortful control on the Stroop Color and Word and Tower of London tasks in the sixth grade, but antisocial behavior did not moderate this association. Multiple group analysis revealed that FA status was associated with higher Stroop interference scores in fourth and sixth grade and lower move scores on the Tower of London task for boys but not girls. Conclusions: The association between FA status and effortful control may be attenuated in middle childhood (fourth grade) but emerge again in early adolescence (sixth grade). The results indicate that sons of alcoholics may be particularly vulnerable to poor self-regulatory strategies and that early adolescence may be an important time for intervening with these families to facilitate higher self-regulation before the transition to high school.

Nolan, Mary

2017-10-01

Objectives To ascertain the knowledge of young people aged 16 to 19 of early brain development and their attitudes towards the care of babies and preschool children. Design Cross-sectional, school- and college-based survey including all sixth form students present on the days of data collection. The survey instrument comprised forced-choice questions in four sections: Demographics, Perceptions and Understanding of Early Childhood Development, Parental Behaviors to Support Early Brain development, and Resource Needs and Usage. Setting Two sixth form schools and one sixth form college in three towns of varying affluence in the West Midlands of the United Kingdom. Method The survey was mounted online and completed by 905 students who returned it directly to the researcher. Results Most students knew that tobacco, alcohol, and drugs are hazardous in pregnancy, and many recognized the impact of maternal stress on fetal brain development. Many believed that babies can be "spoiled" and did not appreciate the importance of reading to babies and of the relationship between play and early brain development. A significant minority thought that physical activity and a healthy diet have little impact on young children's development. Respondents said they would turn firstly to their parents for advice on baby care rather than professionals. Conclusion Young people need educating about parenting activities that support the all-round healthy development of infants. The importance of a healthy diet, physical activity, reading, and play should be included in sixth form curricula and antenatal classes. Consideration should be given to educating grandparents because of their influence on new parents.

A constitutively activating mutation alters the dynamics and energetics of a key conformational change in a ligand-free G protein-coupled receptor.

2013-09-27

G protein-coupled receptors (GPCRs) undergo dynamic transitions between active and inactive conformations. Usually, these conversions are triggered when the receptor detects an external signal, but some so-called constitutively activating mutations, or CAMs, induce a GPCR to bind and activate G proteins in the absence of external stimulation, in ways still not fully understood. Here, we investigated how a CAM alters the structure of a GPCR and the dynamics involved as the receptor transitions between different conformations. Our approach used site-directed fluorescence labeling (SDFL) spectroscopy to compare opsin, the ligand-free form of the GPCR rhodopsin, with opsin containing the CAM M257Y, focusing specifically on key movements that occur in the sixth transmembrane helix (TM6) during GPCR activation. The site-directed fluorescence labeling data indicate opsin is constrained to an inactive conformation both in detergent micelles and lipid membranes, but when it contains the M257Y CAM, opsin is more dynamic and can interact with a G protein mimetic. Further study of these receptors using tryptophan-induced quenching (TrIQ) methods indicates that in detergent, the CAM significantly increases the population of receptors in the active state, but not in lipids. Subsequent Arrhenius analysis of the TrIQ data suggests that, both in detergent and lipids, the CAM lowers the energy barrier for TM6 movement, a key transition required for conversion between the inactive and active conformations. Together, these data suggest that the lowered energy barrier is a primary effect of the CAM on the receptor dynamics and energetics.

Objectives To survey medical students on their ideas of future work-life balance and discuss topics for next-generation medical education. Methods First-year (n=372, 34.9% female) and sixth-year medical students (n=311, 44.1% female) responded to a questionnaire on future self, marriage and childcare, and gender differences at the workplace. Responses were compared between academic years and gender. Responses were evaluated by gender and academic year using the Mann-Whitney U test.  Significance was set at p<0.01. Results The first-year and sixth-year students, regardless of gender, had different views on gender-related favorable treatment at workplaces {U=13464, p=0.000 (first-year), U=10407, p=0.000 (sixth-year)}. A greater percentage of female students would choose career options based on the possibility of marriage and childbirth {U=10689, p=0.000 (first-year), U=10930, p=0.000 (sixth-year)}. Among first-year students, a greater percentage of female students expected to work part-time. Also among first-year students, greater percentages of female students expected to work part-time or leave their jobs temporarily while raising their children. Compared with first-year male students, first-year female students expected to undertake larger portions of the childcare and housework burden than their partners. However, gender differences in work-life balance and childcare leave vanished in the sixth-year students. Conclusions Female medical students accepted childcare and housework burdens as inevitable; the work environment they choose might affect their career development. While support from male partners and institutions must be increased, voluntary actions and change in mentality of female students need to be promoted through medical education to prevent them from waiting passively for the situation to change.

Under flooded conditions, the leaves and internodes of deepwater rice can elongate above the water surface to capture oxygen and prevent drowning. Our previous studies showed that three major quantitative trait loci (QTL) regulate deepwater-dependent internode elongation in deepwater rice. In this study, we investigated the age-dependent internode elongation in deepwater rice. We also investigated the relationship between deepwater-dependent internode elongation and the phytohormone gibberellin (GA) by physiological and genetic approach using a QTL pyramiding line (NIL-1 + 3 + 12). Deepwater rice did not show internode elongation before the sixth leaf stage under deepwater condition. Additionally, deepwater-dependent internode elongation occurred on the sixth and seventh internodes during the sixth leaf stage. These results indicate that deepwater rice could not start internode elongation until the sixth leaf stage. Ultra-performance liquid chromatography tandem mass-spectrometry (UPLC-MS/MS) method for the phytohormone contents showed a deepwater-dependent GA1 and GA4 accumulation in deepwater rice. Additionally, a GA inhibitor abolished deepwater-dependent internode elongation in deepwater rice. On the contrary, GA feeding mimicked internode elongation under ordinary growth conditions. However, mutations in GA biosynthesis and signal transduction genes blocked deepwater-dependent internode elongation. These data suggested that GA biosynthesis and signal transduction are essential for deepwater-dependent internode elongation in deepwater rice. © 2014 The Authors.

The sixth blind test of organic crystal structure prediction (CSP) methods has been held, with five target systems: a small nearly rigid molecule, a polymorphic former drug candidate, a chloride salt hydrate, a co-crystal and a bulky flexible molecule. This blind test has seen substantial growth in the number of participants, with the broad range of prediction methods giving a unique insight into the state of the art in the field. Significant progress has been seen in treating flexible molecules, usage of hierarchical approaches to ranking structures, the application of density-functional approximations, and the establishment of new workflows and ‘best practices’ for performing CSP calculations. All of the targets, apart from a single potentially disordered Z′ = 2 polymorph of the drug candidate, were predicted by at least one submission. Despite many remaining challenges, it is clear that CSP methods are becoming more applicable to a wider range of real systems, including salts, hydrates and larger flexible molecules. The results also highlight the potential for CSP calculations to complement and augment experimental studies of organic solid forms. PMID:27484368

Proceedings of the Sixth NASA Langley Formal Methods (LFM) Workshop

Rozier, Kristin Yvonne (Editor)

2008-01-01

Today's verification techniques are hard-pressed to scale with the ever-increasing complexity of safety critical systems. Within the field of aeronautics alone, we find the need for verification of algorithms for separation assurance, air traffic control, auto-pilot, Unmanned Aerial Vehicles (UAVs), adaptive avionics, automated decision authority, and much more. Recent advances in formal methods have made verifying more of these problems realistic. Thus we need to continually re-assess what we can solve now and identify the next barriers to overcome. Only through an exchange of ideas between theoreticians and practitioners from academia to industry can we extend formal methods for the verification of ever more challenging problem domains. This volume contains the extended abstracts of the talks presented at LFM 2008: The Sixth NASA Langley Formal Methods Workshop held on April 30 - May 2, 2008 in Newport News, Virginia, USA. The topics of interest that were listed in the call for abstracts were: advances in formal verification techniques; formal models of distributed computing; planning and scheduling; automated air traffic management; fault tolerance; hybrid systems/hybrid automata; embedded systems; safety critical applications; safety cases; accident/safety analysis.

Exponential propagators for the Schrödinger equation with a time-dependent potential.

PubMed

Bader, Philipp; Blanes, Sergio; Kopylov, Nikita

2018-06-28

We consider the numerical integration of the Schrödinger equation with a time-dependent Hamiltonian given as the sum of the kinetic energy and a time-dependent potential. Commutator-free (CF) propagators are exponential propagators that have shown to be highly efficient for general time-dependent Hamiltonians. We propose new CF propagators that are tailored for Hamiltonians of the said structure, showing a considerably improved performance. We obtain new fourth- and sixth-order CF propagators as well as a novel sixth-order propagator that incorporates a double commutator that only depends on coordinates, so this term can be considered as cost-free. The algorithms require the computation of the action of exponentials on a vector similar to the well-known exponential midpoint propagator, and this is carried out using the Lanczos method. We illustrate the performance of the new methods on several numerical examples.

The present study used the choice/no-choice method to investigate the effect of math anxiety on the strategy used in computational estimation and mental arithmetic tasks and to examine age-related differences in this regard. Fifty-seven fourth graders, 56 sixth graders, and 60 adults were randomly selected to participate in the experiment. Results showed the following: (1) High-anxious individuals were more likely to use a rounding-down strategy in the computational estimation task under the best-choice condition. Additionally, sixth-grade students and adults performed faster than fourth-grade students on the strategy execution parameter. Math anxiety affected response times (RTs) and the accuracy with which strategies were executed. (2) The execution of the partial-decomposition strategy was superior to that of the full-decomposition strategy on the mental arithmetic task. Low-math-anxious persons provided more accurate answers than did high-math-anxious participants under the no-choice condition. This difference was significant for sixth graders. With regard to the strategy selection parameter, the RTs for strategy selection varied with age. PMID:27803685

Sixth Grade Student Self-Regulation in Science

NASA Astrophysics Data System (ADS)

Reid, Lisa J.

The positive relationship between self-regulation and student achievement has been repeatedly supported through research. Key considerations that have resulted from prior research include instructor feedback and explicit expectations, student perception of their control of their progress, accurate self-calibration, reflection, goal-setting, age, and methods by which a cycle which integrates all of these can be put in place. While research provides evidence for that fact that it is possible to support student success in several of these areas, many questions are left as to how guided, active self-regulation impacts students perception of their control over their performance, their ability to accurately assess and act upon their strengths and weaknesses, and, ultimately, their overall progress at different developmental stages. This study intended to provide a better understanding of how guidance in the self-regulation strategies of sixth grade science students can impact their attitudes toward learning. Specifically, this study investigated the question, "What is the effect of active reflection, graphing of grades, and goal setting on sixth-grade students' locus of control and ability to self-regulate?"

To compare fatty acid composition of human milk at 2 different stages of lactation and investigate the relation between trans isomeric and long-chain polyunsaturated fatty acids (LCPUFAs) in human milk at the sixth month of lactation. We investigated human milk samples obtained at the sixth week and sixth month of lactation from 462 mothers who participated in a large birth cohort study. Fatty acid composition of human milk lipids was determined by high-resolution capillary gas-liquid chromatography. Fat contents of human milk increased significantly between the sixth week and sixth month of lactation (1.63 [2.06] and 3.19 [3.14], g/100 mL; median [interquartile range], P < 0.001). Percentage contributions to human milk fatty acid composition of nearly all polyunsaturated fatty acids also increased significantly (linoleic acid: 10.09 [4.41] and 11.01 [4.53], arachidonic acid: 0.46 [0.32] and 0.48 [0.23], alpha-linolenic acid: 0.69 [0.42] and 0.75 [0.41], and docosahexaenoic acid: 0.17 [0.23] and 0.23 [0.15], % wt/wt, P < 0.001). Values of the 18-carbon trans octadecenoic acid (C18:1n-7/9t) significantly inversely correlated to linoleic acid (r = -0.24, P < 0.001), alpha-linolenic acid (r = -0.19, P < 0.001), and arachidonic acid (r = -0.43, P < 0.001). In contrast, we found no correlation between the 16-carbon trans hexadecenoic acid (C16:1n-7t) and the same LCPUFAs. Data obtained in the present study indicate increasing fat contents with stable or increasing percentage contribution of LCPUFAs in human milk samples between the sixth week and at the sixth month of lactation, and the availability of 18-carbon trans isomeric fatty acids is inversely associated to the availability of several LCPUFAs in human milk at the sixth month of lactation.

The aim of this investigation was to test hypothesized reverse prospective relationships between alcohol consumption and depressive symptomatology as a function of race among youth. In a two-wave prospective study, 328 European American, 328 African American, and 144 Hispanic American youth were studied at the end of fifth grade (last year of elementary school) and the end of sixth grade (first year of middle school). A positive correlation was observed between alcohol consumption and depressive symptoms among all youth. However, the predictive relationship differed based on race. For European American and Hispanic American youth, depressive symptom levels at the end of elementary school predicted alcohol consumption at the end of the first year of middle school, but the converse relationship was not observed. For African American youth, the opposite pattern was found. Alcohol consumption at the end of elementary school predicted depressive symptom levels at the end of the first year of middle school, and the converse relationship was not observed. These findings suggest the possibility that etiological relationships between depression and alcohol use vary by race, thus highlighting the importance of considering race when studying the risk process.

In this article, we analyze the arterial pulse in the spectral domain. A parameter, the spectral harmonic energy ratio (SHER), is developed to assess the features of the overly decreased spectral energy in the fourth to sixth harmonic for palpitation patients. Compared with normal subjects, the statistical results reveal that the mean value of SHER in the patient group (57.7 ± 27.9) is significantly higher than that of the normal group (39.7 ± 20.9) (P-value = .0066 < .01). This means that the total energy in the fourth to sixth harmonic of palpitation patients is significantly less than it is in normal subjects. In other words, the spectral distribution of the arterial pulse gradually decreases for normal subjects while it decreases abruptly in higher-order harmonics (the fourth, fifth and sixth harmonics) for palpitation patients. Hence, SHER is an effective method to distinguish the two groups in the spectral domain. Also, we can thus know that a “gradual decrease” might mean a “balanced” state, whereas an “abrupt decrease” might mean an “unbalanced” state in blood circulation and pulse diagnosis. By SHER, we can determine the ratio of energy distribution in different harmonic bands, and this method gives us a novel viewpoint from which to comprehend and quantify the spectral harmonic distribution of circulation information conveyed by the arterial pulse. These concepts can be further applied to improve the clinical diagnosis not only in Western medicine but also in traditional Chinese medicine (TCM). PMID:21845200

2018-05-01

Superior rectus transposition (SRT) with medial rectus recession has been used for the treatment of sixth nerve palsy and esotropic Duane retraction syndrome (DRS). The purpose of this study was to compare the results of augmented SRT (with scleral fixation) without medial rectus recession in DRS and sixth nerve palsy. Patients with unilateral esotropic DRS (DRS group) and sixth nerve palsy were included in this prospective, comparative study and underwent SRT. Preoperative forced duction testing was negative or slightly positive in both groups. Prospective measurements were compared between the two groups. There were 11 patients in the DRS group and 11 patients in the sixth nerve palsy group. The mean preoperative esotropia decreased from 20.9 ± 6.0 prism diopter (PD) at far to 13.2 ± 5.8 PD in the DRS group (P = 0.003). The same measurement improved from 28.0 ± 8.5 PD to 8.4 ± 7.3 PD in the sixth nerve palsy group (P = 0.003). In the sixth nerve palsy group, the improvement in primary gaze esotropia and abnormal head posture was more than the DRS group (Both P < 0.001).The average dose effect for SRT was 7.8 ± 2.2 PD in the DRS group and 19.2 ± 4.6 PD in the sixth nerve palsy group. Although objective intorsion was significantly induced after SRT, subjective torsion was not significant after surgery in both groups. SRT appears to be more effective in improving primary gaze deviation and head posture in sixth nerve palsy compared with DRS. Subjective torsional and vertical diplopia were rare in both groups.

Purpose One suggested approach to preventing adolescent dating violence is to prevent behavioral precursors to dating violence, such as bullying. However, no longitudinal study has examined bullying as a behavioral precursor to dating violence. In this study, longitudinal data were used to examine (1) whether direct and indirect bullying perpetration in the sixth grade predicted the onset of physical dating violence perpetration by the eighth grade and (2) whether the associations varied by sex and race/ethnicity of the adolescent. Methods Data were collected in school from sixth graders in three primarily rural counties and then again when students were in the eighth grade. Analyses were conducted with 1,154 adolescents who had not perpetrated dating violence at the sixth-grade assessment. The sample was 47% male, 29% black, and 10% of another race/ethnicity than black or white. Results Direct bullying, defined as hitting, slapping, or picking on another kid in the sixth grade, predicted the onset of physical dating violence perpetration by the eighth grade, controlling for indirect bullying and potential confounders. Although indirect bullying, defined as spreading false rumors and excluding students from friendship groups, was associated with the onset of physical dating violence perpetration in bivariate analyses, it did not predict the onset of physical dating violence when controlling for direct bullying. None of the associations examined varied by sex or race/ethnicity of the adolescents. Conclusions Our findings suggest that efforts targeted at preventing direct bullying may also prevent the onset of physical dating violence. PMID:24768162

Information-seeking strategies and science content understandings of sixth-grade students using on-line learning environments

Hoffman, Joseph Loris

1999-11-01

This study examined the information-seeking strategies and science content understandings learners developed as a result of using on-line resources in the University of Michigan Digital Library and on the World Wide Web. Eight pairs of sixth grade students from two teachers' classrooms were observed during inquiries for astronomy, ecology, geology, and weather, and a final transfer task assessed learners' capabilities at the end of the school year. Data included video recordings of students' screen activity and conversations, journals and completed activity sheets, final artifacts, and semi-structured interviews. Learners' information-seeking strategies included activities related to asking, planning, tool usage, searching, assessing, synthesizing, writing, and creating. Analysis of data found a majority of learners posed meaningful, openended questions, used technological tools appropriately, developed pertinent search topics, were thoughtful in queries to the digital library, browsed sites purposefully to locate information, and constructed artifacts with novel formats. Students faced challenges when planning activities, assessing resources, and synthesizing information. Possible explanations were posed linking pedagogical practices with learners' growth and use of inquiry strategies. Data from classroom-lab video and teacher interviews showed varying degrees of student scaffolding: development and critique of initial questions, utilization of search tools, use of journals for reflection on activities, and requirements for final artifacts. Science content understandings included recalling information, offering explanations, articulating relationships, and extending explanations. A majority of learners constructed partial understandings limited to information recall and simple explanations, and these occasionally contained inaccurate conceptualizations. Web site design features had some influence on the construction of learners' content understandings. Analysis of data suggests sites with high quality general design, navigation, and content helped to foster the construction of broad and accurate understandings, while context and interactivity had less impact. However, student engagement with inquiry strategies had a greater impact on the construction of understandings. Gaining accurate and in-depth understandings from on-line resources is a complex process for young learners. Teachers can support students by helping them engage in all phases of the information-seeking process, locate useful information with prescreened resources, build background understanding with off-line instruction, and process new information deeply through extending writing and conversation.

2013-08-01

To characterize lipids and lipoproteins in a diverse school-based cohort and identify features associated with discordance between low-density lipoprotein cholesterol (LDL-C) and LDL particle (LDL-P). Sixth-grade children enrolled in the HEALTHY trial (n = 2384; mean age 11.3 ± 0.6 years; 54.2% female) were evaluated for standard lipids, lipoprotein particles measured by nuclear magnetic resonance, and homeostatic model of insulin resistance. Characteristics of subgroups with values of LDL-C and LDL-P discordant by >20 percentile units, an amount reasoned to be clinically significant, were compared. Four-hundred twenty-eight (18%) of children were in the LDL-P < LDL-C subgroup and 375 (16%) in the LDL-P > LDL-C subgroup. Those with LDL-P > LDL-C had significantly greater body mass index, waist circumference, homeostatic model of insulin resistance, triglycerides, systolic and diastolic blood pressure, and reflected a greater Hispanic ethnic composition but fewer of black race than both the concordant (LDL-P ≅ LDL-C) and opposite discordant (LDL-P < LDL-C) subgroups. There is as much lipoprotein cholesterol compositional heterogeneity in sixth graders as has been described in adults and a discordant atherogenic phenotype of LDL-P > LDL-C, common in obesity, is often missed when only LDL-C is considered. Conversely, many children with moderate-risk cholesterol measures (75th to 99th percentile) have a lower LDL-P burden. Copyright © 2013 Mosby, Inc. All rights reserved.

2016-02-01

The Khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae), is known as one of the mostserious pests of grains in many parts of the world. In this study, the effect of nine barley cultivars (‘Bahman’,‘CB-84-10’, ‘Fajr 30’, ‘Makuyi’, ‘Nosrat’, ‘Yousof’, ‘13A1’, ‘18A1’, and ‘19 A1’) and a wheat cultivar (‘MV17’, as a control) was determined on the nutritional indices and digestive enzymatic activity of T. granarium at 33 6 1C,relative humidity of 6565%, and a photoperiod of 14:10 (L:D) h. The highest and lowest values of larval weight gain of sixth instar were detected on wheat (0.757±0.068 mg) and cultivar Bahman (0.342±0.071 mg). Also, T. granarium larvae fed on cultivar Bahman had the lowest value of efficiency of conversion of ingested food(10.90±2.09%) as compared with wheat and other barley cultivars. Also, the highest midgut amylolytic and proteolytic activities of sixth instar were on cultivar Bahman (0.364±0.024 mU/mg and 80.54±1.73 U/mg, respectively)and the lowest activities were on cultivar Nosrat (0.043±0.004 mU/mg and 7.15±0.01 U/mg, respectively).It is concluded that barley cultivar Bahman was the most unsuitable host for feeding of T. granarium.

2018-01-01

This study addressed school-contextual features of social disorder in relation to sixth-grade students’ experiences of bullying victimization and mental health complaints. It investigated, firstly, whether the school’s concentrations of behavioural problems were associated with individual students’ likelihood of being bullied, and secondly, whether the school’s concentrations of behavioural problems and bullying victimization predicted students’ emotional and psychosomatic health complaints. The data were derived from the Swedish National Survey of Mental Health among Children and Young People, carried out among sixth-grade students (approximately 12–13 years old) in Sweden in 2009. The analyses were based on information from 59,510 students distributed across 1999 schools. The statistical method used was multilevel modelling. While students’ own behavioural problems were associated with an elevated risk of being bullied, attending a school with a higher concentration of students with behavioural problems also increased the likelihood of being bullied. Attending a school with higher levels of bullying victimization and behavioural problems predicted more emotional and psychosomatic complaints, even when adjusting for their individual level analogues. The findings indicate that school-level features of social disorder influence bullying victimization and mental health complaints among students. PMID:29351244

Modulation transfer function of a fish-eye lens based on the sixth-order wave aberration theory.

PubMed

Jia, Han; Lu, Lijun; Cao, Yiqing

2018-01-10

A calculation program of the modulation transfer function (MTF) of a fish-eye lens is developed with the autocorrelation method, in which the sixth-order wave aberration theory of ultra-wide-angle optical systems is used to simulate the wave aberration distribution at the exit pupil of the optical systems. The autocorrelation integral is processed with the Gauss-Legendre integral, and the magnification chromatic aberration is discussed to calculate polychromatic MTF. The MTF calculation results of a given example are then compared with those previously obtained based on the fourth-order wave aberration theory of plane-symmetrical optical systems and with those from the Zemax program. The study shows that MTF based on the sixth-order wave aberration theory has satisfactory calculation accuracy even for a fish-eye lens with a large acceptance aperture. And the impacts of different types of aberrations on the MTF of a fish-eye lens are analyzed. Finally, we apply the self-adaptive and normalized real-coded genetic algorithm and the MTF developed in the paper to optimize the Nikon F/2.8 fish-eye lens; consequently, the optimized system shows better MTF performances than those of the original design.

Moving from answer finding to sensemaking: Supporting middle school students' online inquiry

NASA Astrophysics Data System (ADS)

Zhang, Meilan

Online inquiry, use of the Web as an information source to conduct inquiry for a scientific question, has become increasingly common in middle schools in recent years. However, while valuable Web resources provide unprecedented learning opportunities, easy access to information does not guarantee learning. Previous research has found that middle school students tend to use the Web in a superficial manner. To address the challenges that students face in online inquiry, this study explored several supporting strategies implemented in Digital IdeaKeeper, a scaffolded software tool to help students move from passively finding a ready-made answer to actively making sense of the information they encounter through support for inquiry planning, information search, analysis, and synthesis. This study examined the differences and similarities between regular online inquiry and supported online inquiry performed by several sixth-graders in real classroom settings. Four pairs from a sixth grade class used IdeaKeeper for their online inquiry project, and another four pairs from a different sixth grade class taught by the same teacher used regular online search engines only. Both groups worked on the same science topic-water, and the entire project lasted about four weeks. During that time, students in both groups used computers for about 10-14 days to conduct online research. Multiple sources of data were collected, including video recordings of students' computer activities and conversations, students' artifacts, log files and student final writings. Several themes emerged from the data analysis. First, the findings refer to the importance of providing a structure for students' online inquiry, to promote a more integrated, efficient, continuous, metacognitive and engaging online inquiry. In addition, guidance is important to promote more careful, thorough, and purposeful online reading, Overall, the results suggest that middle school students' online inquiry needs to be structured and their online reading needs to be guided. However, challenges still remain to engage students in high-level critical thinking in online inquiry, because some prompts designed to guide students' reading do not seem effective. Implications of the research findings are discussed.

Under flooded conditions, the leaves and internodes of deepwater rice can elongate above the water surface to capture oxygen and prevent drowning. Our previous studies showed that three major quantitative trait loci (QTL) regulate deepwater-dependent internode elongation in deepwater rice. In this study, we investigated the age-dependent internode elongation in deepwater rice. We also investigated the relationship between deepwater-dependent internode elongation and the phytohormone gibberellin (GA) by physiological and genetic approach using a QTL pyramiding line (NIL-1 + 3 + 12). Deepwater rice did not show internode elongation before the sixth leaf stage under deepwater condition. Additionally, deepwater-dependent internode elongation occurred on the sixth and seventh internodes during the sixth leaf stage. These results indicate that deepwater rice could not start internode elongation until the sixth leaf stage. Ultra-performance liquid chromatography tandem mass-spectrometry (UPLC-MS/MS) method for the phytohormone contents showed a deepwater-dependent GA1 and GA4 accumulation in deepwater rice. Additionally, a GA inhibitor abolished deepwater-dependent internode elongation in deepwater rice. On the contrary, GA feeding mimicked internode elongation under ordinary growth conditions. However, mutations in GA biosynthesis and signal transduction genes blocked deepwater-dependent internode elongation. These data suggested that GA biosynthesis and signal transduction are essential for deepwater-dependent internode elongation in deepwater rice. Deepwater rice obtained the ability for rapid internode elongation to avoid drowning and adapt to flooded condition. How does it regulate internode elongation? Using both physiological and genetic approach, this paper shows that the plant hormone, gibberellin (GA) regulates internode elongation. PMID:24891164

The weight and use of schoolbags in New Zealand secondary schools.

PubMed

Whittfield, J K; Legg, S J; Hedderley, D I

2001-07-15

The weight and use of schoolbags amongst 140 students (70 third form students comprising 35 females and 35 males, and 70 sixth form students comprising 35 females and 35 males) from five New Zealand secondary schools was investigated. Third form students, who were smaller in stature and weight than sixth form students, were found to carry 13.2% of their body weight in schoolbags, while sixth form students carried 10.3% of their body weight. Third form students reported carrying their schoolbags for a longer period of time than sixth form students. Third form students also had less access to lockers to store their schoolbooks and supplies as only one of the five schools investigated provided lockers for third form students, whereas four of the five schools provided lockers for sixth form students. Most students used backpacks to transport their supplies, and these were predominantly carried on two shoulders. Heavy schoolbags, long carriage durations and lack of access to lockers amongst third formers, could contribute to the production or maintenance of musculoskeletal symptoms. This study suggests that third form students may be at a higher risk of developing musculoskeletal symptoms than sixth form students.

Real-time detection of neurite outgrowth using microfluidic device

NASA Astrophysics Data System (ADS)

Kim, Samhwan; Jang, Jongmoon; Choi, Hongsoo; Moon, Cheil

2013-05-01

We developed a simple method for real-time detection of the neurite outgrowth using microfluidic device. Our microfluidic device contains three compartmentalized channels which are for cell seeding, hydrogel and growth factors. Collagen gel is filled in the middle channel and pheochromocytoma (PC12) cells are seeded in the left channel. To induce differentiation of PC12 cells, 50 ng/ml to1000 ng/ml of nerve growth factor (NGF) is introduced into the right channel. After three days of NGF treatment, PC12 cells begin to extend neurites and formed neurite network from sixth day. Quantification of neurite outgrowth is analyzed by measuring the total area of neurites. On sixth day, the area is doubled compared to the area on third day and increases by 20 times on ninth day.

The effect of four instructional methods, gender, and time of testing on the achievement of sixth graders learning to interpret graphs

NASA Astrophysics Data System (ADS)

Young, Jerry Wayne

The purpose of this study was to determine the effects of four instructional methods (direct instruction, computer-aided instruction, video observation, and microcomputer-based lab activities), gender, and time of testing (pretest, immediate posttest for determining the immediate effect of instruction, and a delayed posttest two weeks later to determine the retained effect of the instruction) on the achievement of sixth graders who were learning to interpret graphs of displacement and velocity. The dependent variable of achievement was reflected in the scores earned by students on a testing instrument of established validity and reliability. The 107 students participating in the study were divided by gender and were then randomly assigned to the four treatment groups, each taught by a different teacher. Each group had approximately equal numbers of males and females. The students were pretested and then involved in two class periods of the instructional method which was unique to their group. Immediately following treatment they were posttested and two weeks later they were posttested again. The data in the form of test scores were analyzed with a two-way split-plot analysis of variance to determine if there was significant interaction among technique, gender, and time of testing. When significant interaction was indicated, the Tukey HSD test was used to determine specific mean differences. The results of the analysis indicated no gender effect. Only students in the direct instruction group and the microcomputer-based laboratory group had significantly higher posttest-1 scores than pretest scores. They also had significantly higher posttest-2 scores than pretest scores. This suggests that the learning was retained. The other groups experienced no significant differences among pretest, posttest-1, and posttest-2 scores. Recommendations are that direct instruction and microcomputer-based laboratory activities should be considered as effective stand-alone methods for teaching sixth grade students to interpret graphs of displacement and velocity. However, video and computer instruction may serve as supplemental activities.

Cerebral polyamine metabolism: inhibition of spermidine biosynthesis by dicyclohexylamine.

PubMed

Porta, R; Camardella, M; Gentile, V; De Santis, A

1984-02-01

Since a specific inhibition of cerebral spermidine (Spd) synthase activity by alicyclic amines was preliminarily observed in vitro, we examined the in vivo inhibitory effectiveness of dicyclohexylamine (DCHA) on Spd biosynthesis in 21-day-old rat brain. For this purpose a previously reported HPLC procedure (Porta et al., 1981a) was modified to analyze the cerebral levels of DCHA at the time of polyamine determinations. The intraperitoneally injected DCHA was shown to cross the blood-brain barrier easily, reaching high levels in the cerebral tissue (approximately 750 nmol/g brain) within 1 h of its administration. The effect of the drug on the polyamine metabolism resulted in a significant depletion of Spd biosynthesis from the sixth hour after the treatment and in an earlier and prolonged increase of the putrescine (Pt) steady-state levels. Conversely, the spermine (Spm) endogenous pools remained unchanged throughout the 24-h post-DCHA period. Moreover, following the intracerebral administration of [1,4-14C]Pt, significantly lower specific radioactivity (s.r.a.) values for labeled Pt and Spd were recorded in the brains of DCHA-treated animals. Conversely, after intracerebral [14C]Spd injection, the s.r.a. of newly formed [14C]Spm remained unchanged, confirming the specificity of the DCHA effect on the Spd biosynthesis.

Anaerobic oxidation of ethene coupled to sulfate reduction in microcosms and enrichment cultures.

PubMed

Fullerton, Heather; Crawford, Michael; Bakenne, Ademola; Freedman, David L; Zinder, Stephen H

2013-01-01

Ethene is considered recalcitrant under anaerobic conditions, but biological reduction to ethane and oxidation to CO2 have been reported; however, little is known about these processes or the organisms carrying them out. In this report we describe sulfate dependent ethene consumption in microcosms prepared with sediments from a freshwater canal. A first dose of 0.6 mmol/L ethene was consumed within 77 days, and a second dose was largely consumed twelve days later. Material from this microcosm was transferred into growth medium with ethene as the only electron donor (except for trace amounts of vitamins) and sulfate as the electron acceptor. Four doses of ethene were consumed at increasing rates, and the cultures have been transferred at least eight times in this medium. Conversion of [(14)C]ethene primarily to (14)CO2 was demonstrated in fifth and sixth generation cultures, as well as production of sulfide in other cultures, confirming the ethene/sulfate couple. Ovoid cells 1-2 μm in diameter were found in cultures containing ethene and sulfate, and quantitative PCR showed large increases in bacterial 16S rRNA gene copy number. Over half of a 16S rRNA gene clone library from a sixth-generation culture was a phylotype with a sequence ca. 90% identical with a clade of Deltaproteobacteria that includes Desulfovirga adipica and several Syntrophobacter spp. These studies have solidified the concept that deficits in mass balances for chloroethene fate in sulfate reducing zones of contaminated groundwater sites may be due to ethene oxidation, and suggest a unique phylotype is involved in this process.

Assessment of dental caries prevention program applied to a cohort of elementary school children of Kebemer, a city in Senegal.

PubMed

Daouda, Faye; Aïda, Kanouté; Mbacké, Lo Cheikh; Mamadou, Mbaye

2016-08-01

Dental caries is frequently observed in children, particularly among those residing in developing countries. The most adapted strategies against this pathology remains prevention based on information, education, and communication (IEC), as well as on early diagnosis and treatment. We carried out a study that aimed to analyze the development of dental caries in a cohort of school children followed during their primary education. The objective was to assess the evolution of the dental status of a cohort of students during their elementary curriculum. A cohort of school children was followed during 6 years from the first grade to the sixth grade. Monitoring of these school children focused every year on IEC based on learning methods of brushing messages, dietary advice, systematic visits, fluoride use, and primary dental care. During the school year, the students were periodically subjected to education and communication briefings (IEC). Primary care consisted of extracting and descaling rhizalyzed teeth in the same period. The data from this review were collected using the World Health Organization questionnaire, and statistical analysis was performed with the software Epi-info version 6.04 d. The mean age of the 171 school children was 6 years in the first grade and 11 years in the sixth grade. In the first grade, the decayed permanent teeth prevalence was 31.6% and the In permanent teeth: Decayed, missing or filled teeth (DMF/T) was 0.47. The decayed primary teeth prevalence was 75% and the in primary teeth: decayed or filled teeth (df/t) 2.23. In the sixth year, the prevalence of decayed permanent teeth was 51% and DMF/T 0.36 whereas the decayed primary teeth prevalence was 12% and the df/t was 0.19. The prevalence of decayed permanent teeth increased from 31.6 to 51% whereas the mean DMF/T was not statistically different between school children of the first and sixth grade class. The promotion of oral health by IEC messages and monitoring of children constitute an effective preventive method for children's oral care.

Art at the Bedside: Reflections on Use of Visual Imagery in Hospital Chaplaincy.

PubMed

Dodge-Peters Daiss, Susan

2016-03-01

'Art at the Bedside' is the name given to a hospital visitation program during which works of art loaded onto a computer are used to start conversations with patients and their families. The article traces the genesis of the program that evolved from the author's dual training in art museum education and hospital chaplaincy through the evolution of the practice, now in its sixth year. Reflections on the practice itself are the focus of this article, from identifying the kinds of responses frequently elicited by the artwork to understanding how these works of art seem to forge immediate connections between the patient and the facilitator. Ultimately posed in this reflection is whether the 'Art at the Bedside' experience might suggest a future for the integration of the visual arts more broadly into hospital - and related - chaplaincy. © The Author(s) 2016.

Does overgrowth of costal cartilage cause pectus carinatum? A three-dimensional computed tomography evaluation of rib length and costal cartilage length in patients with asymmetric pectus carinatum

Park, Chul Hwan; Kim, Tae Hoon; Haam, Seok Jin; Lee, Sungsoo

2013-01-01

OBJECTIVES To evaluate whether the overgrowth of costal cartilage may cause pectus carinatum using three-dimensional (3D) computed tomography (CT). METHODS Twenty-two patients with asymmetric pectus carinatum were included. The fourth, fifth and sixth ribs and costal cartilages were semi-automatically traced, and their full lengths were measured on three-dimensional CT images using curved multi-planar reformatted (MPR) techniques. The rib length and costal cartilage length, the total combined length of the rib and costal cartilage and the ratio of the cartilage and rib lengths (C/R ratio) in each patient were compared between the protruding side and the opposite side at the levels of the fourth, fifth and sixth ribs. RESULTS The length of the costal cartilage was not different between the more protruded side and the contralateral side (55.8 ± 9.8 mm vs 55.9 ± 9.3 mm at the fourth, 70 ± 10.8 mm vs 71.6 ± 10.8 mm at the fifth and 97.8 ± 13.2 mm vs 99.8 ± 15.5 mm at the sixth; P > 0.05). There were also no significant differences between the lengths of ribs. (265.8 ± 34.9 mm vs 266.3 ± 32.9 mm at the fourth, 279.7 ± 32.7 mm vs 280.6 ± 32.4 mm at the fifth and 283.8 ± 33.9 mm vs 283.9 ± 32.3 mm at the sixth; P > 0.05). There was no statistically significant difference in either the total length of rib and costal cartilage or the C/R ratio according to side of the chest (P > 0.05). CONCLUSIONS In patients with asymmetric pectus carinatum, the lengths of the fourth, fifth and sixth costal cartilage on the more protruded side were not different from those on the contralateral side. These findings suggest that overgrowth of costal cartilage cannot explain the asymmetric protrusion of anterior chest wall and may not be the main cause of pectus carinatum. PMID:23868604

A modification of the U.S. Geological Survey one-sixth order semiquantitative spectrographic method for the analysis of geologic materials that improves limits of determination of some volatile to moderately volatile elements

USGS Publications Warehouse

Detra, D.E.; Cooley, Elmo F.

1988-01-01

A modification of the one-sixth order semi-quantitative emission spectrographic method for the analysis of 30 elements in geologic materials (Grimes and Marranzino 1968) improves the limits of determination of some volatile to moderately volatile elements. The modification uses a compound-pendulum-mounted filter to regulate the amount of emitted light passing into the spectrograph. One hundred percent transmission of emitted light is allowed during the initial 20 seconds of the burn, then continually reduced to 40 percent over the next 32 seconds using the pendulum-mounted filter, and followed by an additional 68 seconds of burn time. The reduction of light transmission during the latter part of the burn decreases spectral background and the line emission of less volatile elements commonly responsible for problem-causing interferences. The sensitivity of the method for some geochemically important trace elements commonly determined in mineral exploration (Ag, As, Au, Be, Bi, Cd, Cr, Cu, Pb, Sb, Sn, and Zn) is improved up to five-fold under ideal conditions without compromising precision or accuracy

Development of Product Relatedness and Distance Effects in Typical Achievers and in Children With Mathematics Learning Disabilities.

PubMed

Rotem, Avital; Henik, Avishai

2015-01-01

The current study examined the development of two effects that have been found in single-digit multiplication errors: relatedness and distance. Typically achieving (TA) second, fourth, and sixth graders and adults, and sixth and eighth graders with a mathematics learning disability (MLD) performed a verification task. Relatedness was defined by a slow and inaccurate response to false results that were related to one of the operands via a shared multiplication row (e.g., 3 × 4 = 16). Distance was defined by a slow and inaccurate response to false results that were close in magnitude to the true result (e.g., 6 × 8 = 49). The presence of these effects indicates that participants are sensitive to numerical features of products. TA children demonstrated sensitivity to relatedness and distance from second grade onward. With age their sensitivity expanded from easy problems (e.g., 2 × 3) to difficult ones (e.g., 8 × 9). Children with MLD were sensitive to relatedness on easy problems. Their sensitivity to distance differed from the pattern seen in sixth grade and was partial in eighth grade. The presence of numerical sensitivity in children with MLD calls for instructional methods that would further develop their number sense. © Hammill Institute on Disabilities 2014.

2017-01-01

Introduction The ideal nourishment for the first 12 months of a child’s life comes from breastfeeding its mother’s milk, and maternal self-efficacy is one factor which affects breastfeeding duration. Therefore, the present study aimed to compare the maternal breastfeeding self-efficacy during the first week and sixth-week postpartum. Methods This descriptive, analytical study was conducted on 767 women referring to the Family Health Research Center of Rasht in 2014. Mothers were selected through continuous sampling. For data collection, we used demographic questionnaires, and Dennis breastfeeding self-efficacy scale. For data analysis, Chi-square, Mann-Whitney U, Pearson’s correlation coefficient and multiple regression were performed using SPSS version 19. Results In this study, most mothers had scores compatible with moderate self-efficacy in the first week, and in the sixth week had high self-efficacy for breastfeeding. There was a significant relationship between breastfeeding self-efficacy (BSE) score and employment status (p<0.0001). Also, we found significant BSE score differences between primiparous and multiparous women (p<0.001). Conclusion Results of the study indicate that breastfeeding duration increases the breastfeeding self-efficacy levels. So, Developing and implementing appropriate approaches are needed to improve breastfeeding duration in mothers. PMID:28465802

A new adaptively central-upwind sixth-order WENO scheme

NASA Astrophysics Data System (ADS)

Huang, Cong; Chen, Li Li

2018-03-01

In this paper, we propose a new sixth-order WENO scheme for solving one dimensional hyperbolic conservation laws. The new WENO reconstruction has three properties: (1) it is central in smooth region for low dissipation, and is upwind near discontinuities for numerical stability; (2) it is a convex combination of four linear reconstructions, in which one linear reconstruction is sixth order, and the others are third order; (3) its linear weights can be any positive numbers with requirement that their sum equals one. Furthermore, we propose a simple smoothness indicator for the sixth-order linear reconstruction, this smooth indicator not only can distinguish the smooth region and discontinuities exactly, but also can reduce the computational cost, thus it is more efficient than the classical one.

Outdoor alcohol advertising near schools: what does it advertise and how is it related to intentions and use of alcohol among young adolescents?

Pasch, Keryn E; Komro, Kelli A; Perry, Cheryl L; Hearst, Mary O; Farbakhsh, Kian

2007-07-01

The objectives of this study were to (1) document and describe all outdoor alcohol advertisements surrounding schools and (2) examine the association between exposure to alcohol advertising in sixth grade and youth alcohol use, intentions, norms, and attitudes in eighth grade. All outdoor alcohol advertisements within 1,500 feet of 63 Chicago school sites were documented and coded for content and theme. Longitudinal mixed-effects regression analysis was used to determine the association between number of alcohol advertisements around a school in sixth grade and student alcohol behaviors, intentions, norms, and attitudes at the end of eighth grade, 2 years later. Participants included 2,586 sixth-grade students in the 2002-2003 school year. The sample was 37% black, 33% Hispanic, and 15% white. Gender was evenly distributed, and the average age was 12.2 at the end of sixth grade. A total of 931 alcohol advertisements were found within 1,500 feet of the 63 school sites. Exposure to alcohol advertising around schools at the end of sixth grade was found to predict alcohol intentions at the end of eighth grade. This finding held true even for those students who were nonusers of alcohol in sixth grade. Exposure to outdoor alcohol advertising around schools is associated with subsequent youth intentions to use alcohol. The association between exposure to alcohol advertising and youth alcohol-use intentions was found even among sixth-grade nonusers of alcohol, suggesting that even those who have not used alcohol are still influenced by alcohol advertising. These findings suggest that restrictions in alcohol advertising near schools may be warranted.

Adaptive Numerical Dissipative Control in High Order Schemes for Multi-D Non-Ideal MHD

NASA Technical Reports Server (NTRS)

Yee, H. C.; Sjoegreen, B.

2004-01-01

The goal is to extend our adaptive numerical dissipation control in high order filter schemes and our new divergence-free methods for ideal MHD to non-ideal MHD that include viscosity and resistivity. The key idea consists of automatic detection of different flow features as distinct sensors to signal the appropriate type and amount of numerical dissipation/filter where needed and leave the rest of the region free of numerical dissipation contamination. These scheme-independent detectors are capable of distinguishing shocks/shears, flame sheets, turbulent fluctuations and spurious high-frequency oscillations. The detection algorithm is based on an artificial compression method (ACM) (for shocks/shears), and redundant multi-resolution wavelets (WAV) (for the above types of flow feature). These filter approaches also provide a natural and efficient way for the minimization of Div(B) numerical error. The filter scheme consists of spatially sixth order or higher non-dissipative spatial difference operators as the base scheme for the inviscid flux derivatives. If necessary, a small amount of high order linear dissipation is used to remove spurious high frequency oscillations. For example, an eighth-order centered linear dissipation (AD8) might be included in conjunction with a spatially sixth-order base scheme. The inviscid difference operator is applied twice for the viscous flux derivatives. After the completion of a full time step of the base scheme step, the solution is adaptively filtered by the product of a 'flow detector' and the 'nonlinear dissipative portion' of a high-resolution shock-capturing scheme. In addition, the scheme independent wavelet flow detector can be used in conjunction with spatially compact, spectral or spectral element type of base schemes. The ACM and wavelet filter schemes using the dissipative portion of a second-order shock-capturing scheme with sixth-order spatial central base scheme for both the inviscid and viscous MHD flux derivatives and a fourth-order Runge-Kutta method are denoted.

there is little scientific evidence on the relationship between maternal quality of life and type of infant feeding. The purpose of this study was to determine if there were differences in mother's quality of life by type of infant feeding. longitudinal prospective study with 364 women who gave birth at a public hospital at Madrid, Spain, between February and October 2013. To be included, the participants had to be a healthy primigravida aged 18-45 years who gave birth to a healthy newborn with a gestational age between 36 and 42 completed weeks, regardless of birth type. The hospital interviews were performed between 36 and 48 hours post partum in women who had case of vaginal/instrumental births and 60-72 hours post partum for women who had a caesarean birth. Telephone interviews were conducted at the sixth week and sixth month post partum, and included the SF-36 to measure quality of life. SF-36 scores were compared between breast feeding and artificial milk feeding. We also analysed the longitudinal change in SF-36 scores in both groups. at the sixth week post partum, regardless of the infant feeding modality, an increased mental health score was recorded for mothers who reported that their children ate and slept well and for those who did not go to the emergency hospital service because of concern over their baby's health. No significant differences in quality of life were found between the two groups at six months post partum. Between the sixth week and sixth month post partum, quality of life improved significantly in both groups. at the sixth week post partum, the proportion of children who ate and slept well and did not have to attend in an emergency hospital service was higher in the breast feeding group. This observation was associated with greater maternal quality of life. This positive indirect relationship between breast feeding and quality of life should be considered an additional maternal health benefit in the short term. Copyright © 2015 Elsevier Ltd.

The Value of Supplementing Science Education with Outdoor Instruction for Sixth Grade Students

NASA Astrophysics Data System (ADS)

Jackson, Devin Joseph Guilford

Science education is moving away from memorization of facts to inquiry based learning. Adding outdoor instruction can be an effective way to promote this exploratory method of learning. The limited number of empirical studies available have shown significant increase in attitudes and learning with outdoor science instruction. An eight-week quasi-experimental teacher research study was conducted to further this research and assess the value of schoolyard science instruction on student engagement and learning. Participants were 60 students in two sixth grade middle school Earth Science classes. A crossover study design was used with two classes alternating as experimental and control groups. NASA Global Precipitation Measurement mission curriculum was used (NASA/GPM, 2011). While the results did not show a clear increase in student engagement and content knowledge, the study adds to the body of knowledge on outdoor instruction and identifies limitations to consider in future studies.

2018-04-01

To assess the prevalence and sociodemographic determinants of breast-feeding (BF) and exclusive breast-feeding (EBF) in Cyprus up to the sixth month. Cross-sectional and longitudinal descriptive study. BF and EBF were estimated based on mothers' self-reported BF status in line with Step 7 of the WHO/UNICEF Baby-Friendly Hospital Initiative questionnaire and based on 24 h recall. Maternity wards in all public hospitals and twenty-nine (of thirty-five) private maternity clinics nationwide. Consecutive sample of 586 mothers recruited within 48 h from birth, followed up by telephone interview at the first, fourth and sixth month. Although 84·3 % of mothers initiated BF before discharge, prevalence of BF at the sixth month was 32·4 %, with the highest reduction observed between the first and fourth months. Prevalence of EBF at 48 h was 18·8 % and fell gradually to 5·0 % at the sixth month. Mothers with higher educational attainment or higher family income were more likely to breast-feed until the sixth month. In terms of EBF, an association was observed only with education, which persisted until the sixth month. Other than social gradient, mode of delivery was the strongest determinant of BF initiation, exclusivity and continuation. Mothers who gave birth vaginally were three to four times more likely to initiate BF (OR=3·1; 95 % CI 1·7, 5·4) and EBF (OR=4·3; 95 % CI 2·7, 6·8). The low prevalence of BF and EBF in Cyprus, together with the fact that caesarean section rates are currently among the highest in Europe, suggest the need for further research to understand this multidimensional phenomenon and for interdisciplinary policy action to protect, promote and support BF.

Life experience of sixth-grade students in analog domains of sixth-grade science textbooks

NASA Astrophysics Data System (ADS)

Wagamon, Barbara J.

This study was conducted to determine if analog domains in sixth grade science textbooks were common to the life experience of sixth grade students and if experience differed according to moderating variables. The researcher reviewed three sixth grade general science textbooks and selected analogies that were unsupported by extended text, photos, or diagrams. Analogies were limited to ones which were unsupported because the intent was to identify students who were ready by virtue of life experience to confront analogies unaided by contextual clues. The researcher designed the Life Experiences in Analog Domains (LEAD) Questionnaire to survey students in 50 analog domains. Subjects of the study were 331 sixth grade students from an urban school district. Thirty were tested with the instrument one year later. Data on age, gender, ethnicity and income were analyzed for variance. Standardized achievement test scores were correlated to the LEAD Questionnaire. Results revealed sharp contrasts of experience by analog domain. Experience in analog domains was indicated 52% of the time overall. There were significant differences in the experience of students grouped by moderating variables. Younger students reported more experience than older students. The higher income group reported more experience than the lower income group. Caucasian students reported more experience overall than African American students. Chi-square tests revealed that differences in scores by ethnicity were not controlled by income. of three skills, reading comprehension, mathematics, and science, reading comprehension was most closely correlated to questionnaire score. Results suggest that many of the sixth grade students in the study may be without experience in analog domains when they encounter analogies in a textbook. Assuming subsequent implementations of the Questionnaire confirm these results, teachers should survey life experience of students and help them develop experiences that complement their science text. Textbook authors should explain all but the simplest analogies.

Prediction and stability of reading problems in middle childhood.

PubMed

Ritchey, Kristen D; Silverman, Rebecca D; Schatschneider, Christopher; Speece, Deborah L

2015-01-01

The longitudinal prediction of reading problems from fourth grade to sixth grade was investigated with a sample of 173 students. Reading problems at the end of sixth grade were defined by significantly below average performance (≤ 15th percentile) on reading factors defining word reading, fluency, and reading comprehension. Sixth grade poor reader status was predicted by fall of fourth grade passage reading fluency, spelling fluency, and the number of reading problems identified by teachers. Reading fluency and spelling fluency were significant predictors in logistic regression equation that combined to yield a screening battery with an area under the curve of .91. These results suggest that brief assessments of reading and spelling fluency in fourth grade may be able to identify students in middle childhood who have a reading problem or who are at risk for experiencing reading problems in sixth grade. © Hammill Institute on Disabilities 2013.

Mother’s freedom of choice and the rights of an unborn child: a comparison between the views of freshmen and senior medical school students

Motoki, Marcelo Shigueo Yosikawa; Cabar, Fabio Roberto; Francisco, Rossana Pulcineli Vieira

2016-01-01

OBJECTIVES: To compare the views of freshman students with senior students of the Faculty of Medicine- University of São Paulo concerning the respect for the mother’s freedom of choice, the need to protect the unborn child, the proportionality between the mother’s freedom of choice and the protection of the unborn child, and issues related to legal abortion. To determine whether the medical knowledge acquired throughout the academic years can influence the views of medical students on these issues. METHODS: First- and sixth-year students of the Faculty of Medicine – University of São Paulo answered a questionnaire; the inclusion criteria were as follows: a first- or sixth-year student of the medical school and a signature on the free informed consent form. To compare the proportions, a chi-square or Fisher’s exact test was used. The significance level was set to 5%. RESULTS: Regarding the mother’s freedom of choice, in the case when a pregnant woman undergoes a cesarean section by means of a court order despite her intention to not have a cesarean, 55.7% of the first-year students have answered that the mother’s choice should be respected. Among the sixth-year students, only 28.9% believe that the mother’s intention should be considered (p<0.0001). With reference to the mother’s choice in connection with antiretroviral medication, 38.1% of the first-year students agreed that the mother’s intention should be respected, whereas 33% of sixth-year students believed that the mother’s intention should be respected (p=0.453). CONCLUSION: There was a tendency to consider the unborn child’s rights over the mother’s choice as students spent more time in medical school. PMID:27759844

Association of parents' alcohol use and family interaction with the initiation of alcohol use by sixth graders: A preliminary study in Taiwan

PubMed Central

Hung, Chao-Chia; Yen, Lee-Lan; Wu, Wen-Chi

2009-01-01

Background The family is the main environment where children are socialized and learn individual behavior. Although previous studies have examined predictors of preadolescent first alcohol use, few studies have analyzed factors associated with alcohol use in children in a country with low alcohol consumption. The aim of this study was to investigate the initiation of alcohol use by sixth graders and determine family factors associated with first alcohol use. Methods Data used in this study was collected as part of the Child and Adolescent Behaviors in Long-term Evolution (CABLE) project in 2002 (when study participants were in grade 5 and aged 10–11 years) and 2003 (when study participants were in grade 6 and aged 11–12 years). Data from a total of 1,183 participants was analyzed. Main study variables included children's alcohol use: (1) never user (never user in 2002 and 2003), or (2) first-time user (never user in 2002 but ever user in 2003); parents' alcohol use: (1) both parents ever users, (2) mother ever user and father never user, (3) father ever user and mother never user, (4) both parents never users; parental support; and family conflict. Correlates of first alcohol use were identified using logistic regression. Results There were 183 students (15.5%) who became first-time users of alcohol in the sixth grade. Having parents who both used alcohol, less parental support, and more family conflict were significant predictors of sixth graders' first alcohol use. Family interaction and parents' drinking were equally important predictors of preteen's first use of alcohol. Conclusion Family factors influence children's initiation of alcohol use. It is important to educate parents about the effects of alcohol on children and to emphasize the importance of prevention. PMID:19497107

Convergent sum of gradient expansion of the kinetic-energy density functional up to the sixth order term using Padé approximant

NASA Astrophysics Data System (ADS)

Sergeev, A.; Alharbi, F. H.; Jovanovic, R.; Kais, S.

2016-04-01

The gradient expansion of the kinetic energy density functional, when applied to atoms or finite systems, usually grossly overestimates the energy in the fourth order and generally diverges in the sixth order. We avoid the divergence of the integral by replacing the asymptotic series including the sixth order term in the integrand by a rational function. Padé approximants show moderate improvements in accuracy in comparison with partial sums of the series. The results are discussed for atoms and Hooke’s law model for two-electron atoms.

The effects of friendship network popularity on depressive symptoms during early adolescence: moderation by fear of negative evaluation and gender.

PubMed

Kornienko, Olga; Santos, Carlos E

2014-04-01

We integrated a social network analysis and developmental perspectives to examine the effects of friendship network popularity on depressive symptoms during early adolescence. We explored whether the association between social status processes (i.e., friendship network popularity) and depressive symptoms was moderated by socio-cognitive aspects of peer relations (i.e., a fear of negative evaluation by peers) and gender. This longitudinal study was conducted with a sample of 367 adolescents (48.5 % female; M age = 11.9 years; 9 % European American, 19 % African American, 7 % Native American, 60 % Latino(a), 5 % other) attending sixth and seventh grades at Time 1. Results indicated that, for males with high levels of fear of negative evaluation, friendship network popularity was associated negatively with increases in depressive symptoms. Conversely, for females with high levels of fear of negative evaluation, friendship network popularity was associated positively with increases in depressive symptoms. Theoretical and clinical implications are discussed.

2010-01-01

This research investigates the effectiveness of several commonly used methods for teaching the causes of moon phases to sixth grade students. Common teaching methods being investigated are the use of diagrams, animations, modeling/kinesthetics and direct observations of moon phases using a planetarium. Data for each method will be measured by a pre and post assessment of students understanding of moon phases taught using one of the methods. The data will then be used to evaluate the effectiveness of each teaching method individually and comparatively, as well as the method's ability to discourage common misconceptions about moon phases. Results from this research will provide foundational data for the development of educational planetarium shows for the deaf or other linguistically disadvantage children.

Developing a Comprehensive and Comparative Questionnaire for Measuring Personality in Chimpanzees Using a Simultaneous Top-Down/Bottom-Up Design

PubMed Central

Freeman, Hani D.; Brosnan, Sarah F.; Hopper, Lydia M.; Lambeth, Susan P.; Schapiro, Steven J.; Gosling, Samuel D.

2013-01-01

One effective method for measuring personality in primates is to use personality trait ratings to distill the experience of people familiar with the individual animals. Previous rating instruments were created using either top-down or bottom-up approaches. Top-down approaches, which essentially adapt instruments originally designed for use with another species, can unfortunately lead to the inclusion of traits irrelevant to chimpanzees or fail to include all relevant aspects of chimpanzee personality. Conversely, because bottom-up approaches derive traits specifically for chimpanzees, their unique items may impede comparisons with findings in other studies and other species. To address the limitations of each approach, we developed a new personality rating scale using a combined top-down/bottom-up design. Seventeen raters rated 99 chimpanzees on the new 41-item scale, with all but one item being rated reliably. Principal components analysis, using both varimax and direct oblimin rotations, identified six broad factors. Strong evidence was found for five of the factors (Reactivity/Undependability, Dominance, Openness, Extraversion, and Agreeableness). A sixth factor (Methodical) was offered provisionally until more data are collected. We validated the factors against behavioral data collected independently on the chimpanzees. The five factors demonstrated good evidence for convergent and predictive validity, thereby underscoring the robustness of the factors. Our combined top-down/ bottom-up approach provides the most extensive data to date to support the universal existence of these five personality factors in chimpanzees. This framework, which facilitates cross-species comparisons, can also play a vital role in understanding the evolution of personality and can assist with husbandry and welfare efforts. PMID:23733359

May the Inferior Petrosal Sinus Recanalization During Endovascular Treatment for Carotid-Cavernous Fistulas Increase the Risk of Sixth Nerve Palsy?

PubMed

Robert, Thomas; Valsecchi, Daniele; Sylvestre, Philippe; Blanc, Raphaël; Ciccio, Gabriele; Smajda, Stanislas; Redjem, Hocine; Piotin, Michel

2018-05-03

Sixth nerve palsy is a common complication of endovascular treatment for carotid-cavernous fistulas (CCF). Two hypotheses are evoked: the spontaneous venous congestion into the cavernous sinus and the direct compression of the nerve by the embolic agent into the cavernous sinus. Nevertheless, the evidence is still uncertain. Knowing the vicinity of the sixth nerve with the inferior petrosal sinus (IPS) in the Dorello canal, we hypothesized that the recanalization of the IPS increased the risk of nerve damage. We analyzed a prospective database of patients treated for CCFs from March 2009 to April 2016. We excluded patients who did not need treatment, cases of high-flow CCF, and patients lost to follow-up, obtaining a homogeneous population of 82 patients with indirect CCFs. This population was divided in 2 groups: patients without new-onset/worsening of sixth nerve palsy and patients with this postprocedural complication. Our main endpoints were the potential differences between patients with or without recanalization of IPS and between those who underwent or not an embolization with Onyx-18. We did not find any statistically meaningful difference between the 2 groups concerning the necessity of IPS recanalization (P > 0.999, odds ratio 0.97, 95% confidence interval 0.32-2.96) or with the use of Onyx-18 as an embolic agent (P = 0.56; odds ratio 1.41, 95% confidence interval 0.41-2.45). The recanalization of a thrombosed IPS does not increase the risk of procedural sixth nerve damage. The initial injury seems to relate with development/worsening of a sixth nerve palsy.

Behavioral inhibition and childhood stuttering

PubMed Central

Choi, Dahye; Conture, Edward G.; Walden, Tedra A.; Lambert, Warren E.; Tumanova, Victoria

2013-01-01

Purpose The purpose of this study was to assess the relation of behavioral inhibition to stuttering and speech/language output in preschool-age children who do (CWS) and do not stutter (CWNS). Method Participants were preschool-age (ages 36 to 68 months), including 26 CWS (22 males) and 28 CWNS (13 males). Participants’ behavioral inhibition (BI) was assessed by measuring the latency to their sixth spontaneous comment during conversation with an unfamiliar experimenter, using methodology developed by Kagan, Reznick, and Gibbons (1989). In addition to these measures of BI, each participant’s stuttered and non-stuttered disfluencies and mean length of utterance (in morphemes) were assessed. Results Among the more salient findings, it was found that (1) there was no significant difference in BI between preschool-age CWS and CWNS as a group, (2) when extremely high versus low inhibited children were selected, there were more CWS with higher BI and fewer CWS with lower BI when compared to their CWNS peers, and (3) more behaviorally inhibited CWS, when compared to less behaviorally inhibited CWS, exhibited more stuttering. Conclusions Findings are taken to suggest that one aspect of temperament (i.e., behavioral inhibition) is exhibited by some preschool-age CWS and that these children stutter more than CWS with lower behavioral inhibition. The present results seem to support continued study of the association between young children’s temperamental characteristics and stuttering, the diagnostic entity (i.e., CWS versus CWNS), as well as stuttering, the behavior (e.g., frequency of stuttered disfluencies).

2015-01-01

Background: Although exercise has been addressed as an adjuvant treatment for anxiety, depression and cancer-related symptoms, limited studies have evaluated the effectiveness of exercise in patients with lung cancer. Methods: We recruited 116 patients from a medical centre in northern Taiwan, and randomly assigned them to either a walking-exercise group (n=58) or a usual-care group (n=58). We conducted a 12-week exercise programme that comprised home-based, moderate-intensity walking for 40 min per day, 3 days per week, and weekly exercise counselling. The outcome measures included the Hospital Anxiety and Depression Scale and the Taiwanese version of the MD Anderson Symptom Inventory. Results: We analysed the effects of the exercise programme on anxiety, depression and cancer-related symptoms by using a generalised estimating equation method. The exercise group patients exhibited significant improvements in their anxiety levels over time (P=0.009 and 0.006 in the third and sixth months, respectively) and depression (P=0.00006 and 0.004 in the third and sixth months, respectively) than did the usual-care group patients. Conclusions: The home-based walking exercise programme is a feasible and effective intervention method for managing anxiety and depression in lung cancer survivors and can be considered as an essential component of lung cancer rehabilitation.

Hilbert's sixth problem and the failure of the Boltzmann to Euler limit

NASA Astrophysics Data System (ADS)

Slemrod, Marshall

2018-04-01

This paper addresses the main issue of Hilbert's sixth problem, namely the rigorous passage of solutions to the mesoscopic Boltzmann equation to macroscopic solutions of the Euler equations of compressible gas dynamics. The results of the paper are that (i) in general Hilbert's program will fail because of the appearance of van der Waals-Korteweg capillarity terms in a macroscopic description of motion of a gas, and (ii) the van der Waals-Korteweg theory itself might satisfy Hilbert's quest for a map from the `atomistic view' to the laws of motion of continua. This article is part of the theme issue `Hilbert's sixth problem'.

Screw-symmetric gravitational waves: A double copy of the vortex

NASA Astrophysics Data System (ADS)

Ilderton, A.

2018-07-01

Plane gravitational waves can admit a sixth 'screw' isometry beyond the usual five. The same is true of plane electromagnetic waves. From the point of view of integrable systems, a sixth isometry would appear to over-constrain particle dynamics in such waves; we show here, though, that no effect of the sixth isometry is independent of those from the usual five. Many properties of particle dynamics in a screw-symmetric gravitational wave are also seen in a (non-plane-wave) electromagnetic vortex; we make this connection explicit, showing that the screw-symmetric gravitational wave is the classical double copy of the vortex.

Weyers, Simone; Noack, Thorsten; Rehkämper, Gerd

2014-01-01

Background and aim: The dissection course is an essential part of preclinical medical education. At the Medical Faculty of Duesseldorf, an education concept has been developed with the aim, to reflect with students their experiences and to support them in dealing with the donor and preparation. The aim of this paper is to present the concept. Method: The education concept had a peer group approach. It comprised a lecture, a small group seminar and an online diary as core element. Finally, the concept was evaluated. Results: Approximately one sixth of students made use of the online diary. Selected entries are presented here. Also, one sixth of students took part in the evaluation. They rated the activity as helpful to prepare for the dissection course. Discussion: The education concept could be a corner stone of a longitudinal training to promote the adequate encounter with topics such as dying and death. PMID:24872851

Characterization and Performance of the Cananea Near-infrared Camera (CANICA)

NASA Astrophysics Data System (ADS)

Devaraj, R.; Mayya, Y. D.; Carrasco, L.; Luna, A.

2018-05-01

We present details of characterization and imaging performance of the Cananea Near-infrared Camera (CANICA) at the 2.1 m telescope of the Guillermo Haro Astrophysical Observatory (OAGH) located in Cananea, Sonora, México. CANICA has a HAWAII array with a HgCdTe detector of 1024 × 1024 pixels covering a field of view of 5.5 × 5.5 arcmin2 with a plate scale of 0.32 arcsec/pixel. The camera characterization involved measuring key detector parameters: conversion gain, dark current, readout noise, and linearity. The pixels in the detector have a full-well-depth of 100,000 e‑ with the conversion gain measured to be 5.8 e‑/ADU. The time-dependent dark current was estimated to be 1.2 e‑/sec. Readout noise for correlated double sampled (CDS) technique was measured to be 30 e‑/pixel. The detector shows 10% non-linearity close to the full-well-depth. The non-linearity was corrected within 1% levels for the CDS images. Full-field imaging performance was evaluated by measuring the point spread function, zeropoints, throughput, and limiting magnitude. The average zeropoint value in each filter are J = 20.52, H = 20.63, and K = 20.23. The saturation limit of the detector is about sixth magnitude in all the primary broadbands. CANICA on the 2.1 m OAGH telescope reaches background-limited magnitudes of J = 18.5, H = 17.6, and K = 16.0 for a signal-to-noise ratio of 10 with an integration time of 900 s.

Urbanization and agricultural land loss in India: comparing satellite estimates with census data.

PubMed

Pandey, Bhartendu; Seto, Karen C

2015-01-15

We examine the impacts of urbanization on agricultural land loss in India from 2001 to 2010. We combined a hierarchical classification approach with econometric time series analysis to reconstruct land-cover change histories using time series MODIS 250 m VI images composited at 16-day intervals and night time lights (NTL) data. We compared estimates of agricultural land loss using satellite data with agricultural census data. Our analysis highlights six key results. First, agricultural land loss is occurring around smaller cities more than around bigger cities. Second, from 2001 to 2010, each state lost less than 1% of its total geographical area due to agriculture to urban expansion. Third, the northeastern states experienced the least amount of agricultural land loss. Fourth, agricultural land loss is largely in states and districts which have a larger number of operational or approved SEZs. Fifth, urban conversion of agricultural land is concentrated in a few districts and states with high rates of economic growth. Sixth, agricultural land loss is predominantly in states with higher agricultural land suitability compared to other states. Although the total area of agricultural land lost to urban expansion has been relatively low, our results show that since 2006, the amount of agricultural land converted has been increasing steadily. Given that the preponderance of India's urban population growth has yet to occur, the results suggest an increase in the conversion of agricultural land going into the future.

Convert a low-cost sensor to a colorimeter using an improved regression method

NASA Astrophysics Data System (ADS)

Wu, Yifeng

2008-01-01

Closed loop color calibration is a process to maintain consistent color reproduction for color printers. To perform closed loop color calibration, a pre-designed color target should be printed, and automatically measured by a color measuring instrument. A low cost sensor has been embedded to the printer to perform the color measurement. A series of sensor calibration and color conversion methods have been developed. The purpose is to get accurate colorimetric measurement from the data measured by the low cost sensor. In order to get high accuracy colorimetric measurement, we need carefully calibrate the sensor, and minimize all possible errors during the color conversion. After comparing several classical color conversion methods, a regression based color conversion method has been selected. The regression is a powerful method to estimate the color conversion functions. But the main difficulty to use this method is to find an appropriate function to describe the relationship between the input and the output data. In this paper, we propose to use 1D pre-linearization tables to improve the linearity between the input sensor measuring data and the output colorimetric data. Using this method, we can increase the accuracy of the regression method, so as to improve the accuracy of the color conversion.

Design, Synthesis and Mechanistic Evaluation of Iron-Based Catalysis for Synthesis Gas Conversion to Fuels and Chemicals

DOE Office of Scientific and Technical Information (OSTI.GOV)

Akio Ishikawa; Manuel Ojeda; Nan Yao

2007-03-31

This project extends previously discovered Fe-based catalysts to hydrogen-poor synthesis gas streams derived from coal and biomass sources. These catalysts have shown unprecedented Fischer-Tropsch synthesis rates and selectivities for synthesis gas derived from methane. During the first reporting period, we certified a microreactor, installed required analytical equipment, and reproduced synthetic protocols and catalytic results previously reported. During the second reporting period, we prepared several Fe-based compositions for Fischer-Tropsch Synthesis and tested the effects of product recycle under both subcritical and supercritical conditions. During the third and fourth reporting periods, we improved the catalysts preparation method, which led to Fe-based materialsmore » with the highest FTS reaction rates and selectivities so far reported, a finding that allowed their operation at lower temperatures and pressures with high selectivity to desired products (C{sub 5+}, olefins). During the fifth and sixth reporting period, we studied the effects of different promoters on catalytic performance, specifically how their sequence of addition dramatically influenced the performance of these materials in the Fischer-Tropsch synthesis. We also continued our studies of the kinetic behavior of these materials during the sixth reporting period. Specifically, the effects of H{sub 2}, CO, and CO{sub 2} on the rates and selectivities of Fischer-Tropsch Synthesis reactions led us to propose a new sequence of elementary steps on Fe and Co Fischer-Tropsch catalysts. Finally, we also started a study of the use of colloidal precipitation methods for the synthesis small Co clusters using recently developed methods to explore possible further improvements in FTS rates and selectivities. We found that colloidal synthesis makes possible the preparation of small cobalt particles, although large amount of cobalt silicate species, which are difficult to reduce, were formed. During this seventh reporting period, we have explored several methods to modify the silanol groups on SiO{sub 2} by using either a homogeneous deposition-precipitation method or surface titration of Si-OH on SiO{sub 2} with zirconium (IV) ethoxide to prevent the formation of unreducible and unreactive CoO{sub x} species during synthesis and FTS catalysis. We have synthesized monometallic Co/ZrO{sub 2}/SiO{sub 2} catalysts with different Co loadings (11-20 wt%) by incipient wetness impregnation methods and characterized the prepared Co supported catalysts by H{sub 2} temperature-programmed reduction (H{sub 2}-TPR) and H{sub 2}-chemisorption. We have measured the catalytic performance in FTS reactions and shown that although the hydroxyl groups on the SiO{sub 2} surface are difficult to be fully titrated by ZrO{sub 2}, modification of ZrO{sub 2} on SiO{sub 2} surface can improve the Co clusters dispersion and lead to a larger number of exposed Co surface atoms after reduction and during FTS reactions. During this seventh reporting period, we have also advanced our development of the reaction mechanism proposed in the previous reporting period. Specifically, we have shown that our novel proposal for the pathways involved in CO activation on Fe and Co catalysts is consistent with state-of-the-art theoretical calculations carried out in collaboration with Prof. Manos Mavrikakis (University of Wisconsin-Madison). Finally, we have also worked on the preparation of several manuscripts describing our findings about the preparation, activation and mechanism of the FTS with Fe-based catalysts and we have started redacting the final report for this project.« less

Recurrent Isolated Sixth Nerve Palsy in Relapsing-Remitting Chronic Inflammatory Demyelinating Polyneuropathy.

PubMed

Al-Bustani, Najwa; Weiss, Michael D

2015-09-01

Chronic inflammatory demyelinating polyneuropathy (CIDP) is an immune-mediated sensory and motor demyelinating polyneuropathy that typically presents as a relapsing-remitting or progressive disorder. Cranial neuropathies infrequently occur in association with other more typical symptoms of CIDP. We report a case of CIDP with recurrent isolated sixth nerve palsy. Her physical examination showed a right sixth nerve palsy and absent deep tendon reflexes as the only indicator of her disease. Magnetic resonance imaging revealed thickening without enhancement of the trigeminal and sixth cranial nerves. Nerve conduction study (NCS) revealed a sensory and motor demyelinating polyneuropathy with conduction block and temporal dispersion in multiple nerves consistent with CIDP. Cerebrospinal fluid demonstrated albuminic-cytologic dissociation. She had a remarkable response to intravenous immunoglobulin and remains asymptomatic without any additional immunomodulating therapy. Isolated cranial neuropathies can rarely occur as the sole manifestation of relapsing-remitting CIDP. The profound demyelination found on NCS in this case demonstrates that there can be a dramatic discordance between the clinical and electrodiagnostic findings in some patients with this disorder.

[The Status, Change and Health Issues of Inpatients' Sixth Vital Sign in a Medical Center].

2017-04-01

Hospitalized patients generally have elevated levels of emotional distress. Gaining a better under-standing of the problem of emotional distress among hospitalized patients is conducive to providing appropriate emotional care and promoting their recovery. To analyze the scores for the "sixth vital sign" (i.e., emotional distress), diversification, and the health-related problems of hospitalized patients at a medical center in Taiwan. The results may offer an important reference for providing effective emotional care to hospitalized patients. A retrospective descriptive research design was used. Data were collected from all of the 27,885 inpatients that were registered at the target hospital in 2013. Further, a total of 245,814 attendance records were assessed to extract the data that were relevant to emotional distress. The findings revealed that 58.3% of hospitalized patients had earned a sixth vital sign score ≥ 1 and that 0.8% of these patients had earned a score ≥ 4. On the whole, the sixth vital sign scores of hospitalized patients were found to decrease progressively with the number of hospitalization days except for hematology and oncology, neurosurgery, and plastic surgery patients. The highest emotional distress scores were found among family medicine, dermatology, and plastic surgery patients. Moreover, emotional distress scores were significantly higher in patients who had health problems that involved pain, anxiety, or sleep disorder. The present study suggests that improving the emotional care of hematology, oncology, neurosurgery, family medicine, dermatology, and plastic surgery patients and of patients with health problems involving pain, anxiety, or sleep disorder may significantly improve the quality of inpatient holistic healthcare. Only 0.8% of the subjects in the present study had an emotional distress score ≥ 4, which is significantly lower than the level reported in other similar studies. Our findings suggest that related education and training for nursing staffs may improve their assessment and care practices in caring for patients with emotional distress. Furthermore, using more appropriate words, methods, and environments to evaluate the emotional distress of patients holds the potential to improve assessment and care for these patients.

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

NASA Astrophysics Data System (ADS)

Peng, Li-Wei

2009-12-01

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

Weiss, Kathleen D; Vargas, Christina R; Ho, Olivia A; Chuang, Danielle J; Weiss, Jonathan; Lee, Bernard T

2016-11-01

Patients seeking health information commonly use the Internet as the first source for material. Studies show that well-informed patients have increased involvement, satisfaction, and healthcare outcomes. As one-third of Americans have only basic or below basic health literacy, the National Institutes of Health and American Medical Association recommend patient-directed health resources be written at a sixth-grade reading level. This study evaluates the readability of commonly accessed online resources on lung cancer. A search for "lung cancer" was performed using Google and Bing, and the top 10 websites were identified. Location services were disabled, and sponsored sites were excluded. Relevant articles (n = 109) with patient-directed content available directly from the main sites were downloaded. Readability was assessed using 10 established methods and analyzed with articles grouped by parent website. The average reading grade level across all sites was 11.2, with a range from 8.8 (New Fog Count) to 12.2 (Simple Measure of Gobbledygook). The average Flesch Reading Ease score was 52, corresponding with fairly difficult to read text. The readability varied when compared by individual website, ranging in grade level from 9.2 to 15.2. Only 10 articles (9%) were written below a sixth-grade level and these tended to discuss simpler topics. Patient-directed online information about lung cancer exceeds the recommended sixth-grade reading level. Readability varies between individual websites, allowing physicians to direct patients according to level of health literacy. Modifications to existing materials can significantly improve readability while maintaining content for patients with low health literacy. Copyright © 2016 Elsevier Inc. All rights reserved.

Measuring the ambiguity tolerance of medical students: a cross-sectional study from the first to sixth academic years

PubMed Central

2014-01-01

Background Tolerance of ambiguity, or the extent to which ambiguous situations are perceived as desirable, is an important component of the attitudes and behaviors of medical students. However, few studies have compared this trait across the years of medical school. General practitioners are considered to have a higher ambiguity tolerance than specialists. We compared ambiguity tolerance between general practitioners and medical students. Methods We designed a cross-sectional study to evaluate the ambiguity tolerance of 622 medical students in the first to sixth academic years. We compared this with the ambiguity tolerance of 30 general practitioners. We used the inventory for measuring ambiguity tolerance (IMA) developed by Reis (1997), which includes three measures of ambiguity tolerance: openness to new experiences, social conflicts, and perception of insoluble problems. Results We obtained a total of 564 complete data sets (return rate 90.1%) from medical students and 29 questionnaires (return rate 96.7%) from general practitioners. In relation to the reference groups defined by Reis (1997), medical students had poor ambiguity tolerance on all three scales. No differences were found between those in the first and the sixth academic years, although we did observe gender-specific differences in ambiguity tolerance. We found no differences in ambiguity tolerance between general practitioners and medical students. Conclusions The ambiguity tolerance of the students that we assessed was below average, and appeared to be stable throughout the course of their studies. In contrast to our expectations, the general practitioners did not have a higher level of ambiguity tolerance than the students did. PMID:24405525

In this article, the authors accentuate the signs and symptoms of conversion disorder and the significance of clinical judgment and expertise in order to reach the right diagnosis. The authors review the literature and provide information on the etiology, prevalence, diagnostic criteria, and the treatment methods currently employed in the management of conversion disorder. Of note, the advancements of neuropsychology and brain imaging have led to emergence of a relatively sophisticated picture of the neuroscientific psychopathology of complex mental illnesses, including conversion disorder. The available evidence suggests new methods with which to test hypotheses about the neural circuits underlying conversion symptoms. In context of this, the authors also explore the neurobiological understanding of conversion disorder.

PubMed

Piver, M S; Corson, S L; Bolognese, R J

1967-08-01

Hypertensive blood pressure readings were recorded in 282 women from a group of 1025 consecutive patients returning for their sixth-week postpartum visit. Of the 282 women, 120 were classified as toxemic; however, 162 (58%) had had no elevation of blood pressure antepartum, intrapartum, or during the immediate postpartum period. In addition, 100 women with normal sixth-week postpartum blood pressures were randomly selected as controls. A retrospective analysis of their records showed sixth-week postpartum hypertension to occur much less frequently (13%) in nulliparous women, as compared to the preeclamptic nulliparous patients (31%). With the exception of proteinuria, all of the other data studied failed to reveal any significant abnormalities in the late postpartum hypertensive group of patients.

PubMed Central

Copping, Kristine E.; Kurtz-Costes, Beth; Rowley, Stephanie J.; Wood, Dana

2012-01-01

Age and race differences in race stereotype awareness and endorsement were examined in 382 Black and White fourth, sixth, and eighth graders. Youth reported their own beliefs and their perceptions of adults’ beliefs about racial differences in ability in two domains: academics and sports. Children’s own endorsement of race stereotypes was highly correlated with their perceptions of adults’ race stereotypes. Blacks reported stronger traditional sports stereotypes than Whites, and fourth- and sixth-grade Blacks reported roughly egalitarian academic stereotypes. At every grade level, Whites reported academic stereotypes that favored Whites, and sixth and eighth grade Whites reported sports stereotypes that favored Blacks. Results support the tenets of status theory and have implications for identity development and achievement motivation in adolescents. PMID:23729837

Development of Support Service for Prevention and Recovery from Dementia and Science of Lethe

NASA Astrophysics Data System (ADS)

Otake, Mihoko

Purpose of this study is to explore service design method through the development of support service for prevention and recovery from dementia towards science of lethe. We designed and implemented conversation support service via coimagination method based on multiscale service design method, both were proposed by the author. Multiscale service model consists of tool, event, human, network, style and rule. Service elements at different scales are developed according to the model. Interactive conversation supported by coimagination method activates cognitive functions so as to prevent progress of dementia. This paper proposes theoretical bases for science of lethe. Firstly, relationship among coimagination method and three cognitive functions including division of attention, planning, episodic memory which decline at mild cognitive imparement. Secondly, thought state transition model during conversation which describes cognitive enhancement via interactive communication. Thirdly, Set Theoretical Measure of Interaction is proposed for evaluating effectiveness of conversation to cognitive enhancement. Simulation result suggests that the ideas which cannot be explored by each speaker are explored during interactive conversation. Finally, coimagination method compared with reminiscence therapy and its possibility for collaboration is discussed.

A method for determining the conversion efficiency of multiple-cell photovoltaic devices

NASA Astrophysics Data System (ADS)

Glatfelter, Troy; Burdick, Joseph

A method for accurately determining the conversion efficiency of any multiple-cell photovoltaic device under any arbitrary reference spectrum is presented. This method makes it possible to obtain not only the short-circuit current, but also the fill factor, the open-circuit voltage, and hence the conversion efficiency of a multiple-cell device under any reference spectrum. Results are presented which allow a comparison of the I-V parameters of two-terminal, two- and three-cell tandem devices measured under a multiple-source simulator with the same parameters measured under different reference spectra. It is determined that the uncertainty in the conversion efficiency of a multiple-cell photovoltaic device obtained with this method is less than +/-3 percent.

Searching for a sense of purpose: the role of parents and effects on self-esteem among female adolescents.

PubMed

Blattner, Meghan C C; Liang, Belle; Lund, Terese; Spencer, Renee

2013-10-01

Achieving a sense of purpose during adolescence is a developmental asset; however, searching for that purpose may be a developmental stressor. Supportive parent-child relationships may help youth during this stressful experience. The present study included 207 female students in the sixth, eighth, and tenth grades from two competitive private schools. Searching for purpose negatively predicted self-esteem. Hierarchical linear regression examined moderating effects of parental trust and alienation on searching for purpose as a predictor of self-esteem. Parental alienation significantly moderated the association between search for purpose and girls' self-esteem; conversely, parental trust did not moderate the association. Results suggest that parent-child relationships characterized by high levels of parental alienation may exacerbate the pernicious effects of search for purpose. Person-based analyses found four clusters corresponding to Foreclosed Purpose, Diffused Purpose, Uncommitted Purpose/Moratorium, and Achieved Purpose. We discuss implications for practice and research based on these results. Copyright © 2013 The Foundation for Professionals in Services for Adolescents. Published by Elsevier Ltd.

2016-01-01

The Justinianic Plague, which started in the sixth century and lasted to the mid eighth century, is thought to be the first of three historically documented plague pandemics causing massive casualties. Historical accounts and molecular data suggest the bacterium Yersinia pestis as its etiological agent. Here we present a new high-coverage (17.9-fold) Y. pestis genome obtained from a sixth-century skeleton recovered from a southern German burial site close to Munich. The reconstructed genome enabled the detection of 30 unique substitutions as well as structural differences that have not been previously described. We report indels affecting a lacl family transcription regulator gene as well as nonsynonymous substitutions in the nrdE, fadJ, and pcp genes, that have been suggested as plague virulence determinants or have been shown to be upregulated in different models of plague infection. In addition, we identify 19 false positive substitutions in a previously published lower-coverage Y. pestis genome from another archaeological site of the same time period and geographical region that is otherwise genetically identical to the high-coverage genome sequence reported here, suggesting low-genetic diversity of the plague during the sixth century in rural southern Germany.

Persuasive Conversational Agent with Persuasion Tactics

NASA Astrophysics Data System (ADS)

Narita, Tatsuya; Kitamura, Yasuhiko

Persuasive conversational agents persuade people to change their attitudes or behaviors through conversation, and are expected to be applied as virtual sales clerks in e-shopping sites. As an approach to create such an agent, we have developed a learning agent with the Wizard of Oz method in which a person called Wizard talks to the user pretending to be the agent. The agent observes the conversations between the Wizard and the user, and learns how to persuade people. In this method, the Wizard has to reply to most of the user's inputs at the beginning, but the burden gradually falls because the agent learns how to reply as the conversation model grows.

Bayesian Population Genomic Inference of Crossing Over and Gene Conversion

PubMed Central

Padhukasahasram, Badri; Rannala, Bruce

2011-01-01

Meiotic recombination is a fundamental cellular mechanism in sexually reproducing organisms and its different forms, crossing over and gene conversion both play an important role in shaping genetic variation in populations. Here, we describe a coalescent-based full-likelihood Markov chain Monte Carlo (MCMC) method for jointly estimating the crossing-over, gene-conversion, and mean tract length parameters from population genomic data under a Bayesian framework. Although computationally more expensive than methods that use approximate likelihoods, the relative efficiency of our method is expected to be optimal in theory. Furthermore, it is also possible to obtain a posterior sample of genealogies for the data using this method. We first check the performance of the new method on simulated data and verify its correctness. We also extend the method for inference under models with variable gene-conversion and crossing-over rates and demonstrate its ability to identify recombination hotspots. Then, we apply the method to two empirical data sets that were sequenced in the telomeric regions of the X chromosome of Drosophila melanogaster. Our results indicate that gene conversion occurs more frequently than crossing over in the su-w and su-s gene sequences while the local rates of crossing over as inferred by our program are not low. The mean tract lengths for gene-conversion events are estimated to be ∼70 bp and 430 bp, respectively, for these data sets. Finally, we discuss ideas and optimizations for reducing the execution time of our algorithm. PMID:21840857

Preparation, characterization and catalytic activity of ZrO2/bamboo leaves ash (BLA) catalyst for conversion of rice bran oil to biodiesel have been investigated. The catalyst was prepared by impregnation method of ZrOCl2 as ZrO2 precursor with BLA at a theoretical content of 20% wt. followed by calcination. The physicochemical properties of the catalyst material were characterized by x-ray diffraction (XRD), FTIR and surface acidity measurement. Activity test of materials in biodiesel conversion of rice bran oil was used by reflux method and microwave (MW) assisted method. Reaction variables studied in the investigation were the effect of catalyst weight and time of MW irradiation compared with the use reflux method. The results showed that ZrO2/BLA catalyst exhibited competitively effective and efficient processes for the production of biodiesel. The reflux method demonstrated an higher conversion (%) compared to MW method, however MW method showed the better reusable properties.

AIM:To investigate the efficacy of 6-mercaptopurine (6-MP) in cases of azathioprine (AZA) hypersensitivity in patients with inflammatory bowel disease. METHODS: Twenty nine previously confirmed Crohn’s disease (CD) (n = 14) and ulcerative colitis (UC) (n = 15) patients with a known previous (AZA) hypersensitivity reaction were studied prospectively. The 6-MP doses were gradually increased from 0.5 up to 1.0-1.5 mg/kg per day. Clinical activity indices (CDAI/CAI), laboratory variables and daily doses of oral 5-ASA, corticosteroids, and 6-MP were assessed before and in the first, sixth and twelfth months of treatment. RESULTS: In 9 patients, 6-MP was withdrawn in the first 2 wk due to an early hypersensitivity reaction. Medication was ineffective within 6 mo in 6 CD patients, and myelotoxic reaction was observed in two. Data were evaluated at the end of the sixth month in 12 (8 UC, 4 CD) patients, and after the first year in 9 (6 UC, 3 CD) patients. CDAI decreased transiently at the end of the sixth month, but no significant changes were observed in the CDAI or the CAI values at the end of the year. Leukocyte counts (P = 0.01), CRP (P = 0.02), and serum iron (P = 0.05) values indicated decreased inflammatory reactions, especially in the UC patients at the end of the year, making the possibility to taper oral steroid doses. CONCLUSION: About one-third of the previously AZA-intolerant patients showed adverse effects on taking 6MP. In our series, 20 patients tolerated 6MP, but it was ineffective in 8 CD cases, and valuable mainly in ulcerative colitis patients. PMID:18666323

Effect of Vitamin E on Oxaliplatin-induced Peripheral Neuropathy Prevention: A Randomized Controlled Trial

PubMed Central

Salehi, Zeinab; Roayaei, Mahnaz

2015-01-01

Background: Peripheral neuropathy is one of the most important limitations of oxaliplatin base regimen, which is the standard for the treatment of colorectal cancer. Evidence has shown that Vitamin E may be protective in chemotherapy-induced peripheral neuropathy. The aim of this study is to evaluate the effect of Vitamin E administration on prevention of oxaliplatin-induced peripheral neuropathy in patients with colorectal cancer. Methods: This was a prospective randomized, controlled clinical trial. Patients with colorectal cancer and scheduled to receive oxaliplatin-based regimens were enrolled in this study. Enrolled patients were randomized into two groups. The first group received Vitamin E at a dose of 400 mg daily and the second group observed, until after the sixth course of the oxaliplatin regimen. For oxaliplatin-induced peripheral neuropathy assessment, we used the symptom experience diary questionnaire that completed at baseline and after the sixth course of chemotherapy. Only patients with a score of zero at baseline were eligible for this study. Results: Thirty-two patients were randomized to the Vitamin E group and 33 to the control group. There was no difference in the mean peripheral neuropathy score changes (after − before) between two groups, after sixth course of the oxaliplatin base regimen (mean difference [after − before] of Vitamin E group = 6.37 ± 2.85, control group = 6.57 ± 2.94; P = 0.78). Peripheral neuropathy scores were significantly increased after intervention compared with a base line in each group (P < 0.001). Conclusions: The results from this current trial demonstrate a lack of benefit for Vitamin E in preventing oxaliplatin-induced peripheral neuropathy. PMID:26682028

HEALTHY was a 3-year middle school-based primary prevention trial to reduce modifiable risk factors for type 2 diabetes in youth. The study was conducted at seven centers across the country. This paper describes the recruitment and retention activities employed in the study. Schools and students were the focus of recruitment and retention. Each center was responsible for the recruitment of six schools; eligibility was based on ability to enroll a sufficient number of predominately minority and lower socioeconomic status students. Study staff met with district superintendents and school principals to verify the eligibility of schools, and to ascertain how appropriate the school would be for conducting the trial. Sixth grade students were recruited employing a variety of techniques; students and their parents did not know whether their school was randomized to the intervention or control arm. This cohort was followed through sixth, seventh and eighth grades. In the eighth grade, an additional sample of students who were not originally enrolled in the study was recruited in a similar manner to participate in data collection to allow for cross-sectional and dose-response secondary analyses. Parents signed informed consent forms and children signed informed assent forms, as per the needs of the local Institutional Review Board. Parents received a letter describing the results of the health screening for their children after data collection in sixth and eighth grades. Retention of schools and students was critical for the success of the study and was encouraged through the use of financial incentives and other strategies. To a large extent, student withdrawal due to out-migration (transfer and geographical relocation) was beyond the ability of the study to control. A multi-level approach that proactively addressed school and parent concerns was crucial for the success of recruitment and retention in the HEALTHY study.

Background Phantom vibration syndrome is a type of hallucination reported among mobile phone users in the general population. Another similar perception, phantom ringing syndrome, has not been previously described in the medical literature. Methods A prospective longitudinal study of 74 medical interns (46 males, 28 females; mean age, 24.8±1.2 years) was conducted using repeated investigations of the prevalence and associated factors of phantom vibration and ringing. The accompanying symptoms of anxiety and depression were evaluated with the Beck Anxiety and Depression Inventories before the internship began, and again at the third, sixth, and twelfth internship months, and two weeks after the internship ended. Results The baseline prevalence of phantom vibration was 78.1%, which increased to 95.9% and 93.2% in the third and sixth internship months. The prevalence returned to 80.8% at the twelfth month and decreased to 50.0% 2 weeks after the internship ended. The baseline prevalence of phantom ringing was 27.4%, which increased to 84.9%, 87.7%, and 86.3% in the third, sixth, and twelfth internship months, respectively. This returned to 54.2% two weeks after the internship ended. The anxiety and depression scores also increased during the internship, and returned to baseline two weeks after the internship. There was no significant correlation between phantom vibration/ringing and symptoms of anxiety or depression. The incidence of both phantom vibration and ringing syndromes significantly increased during the internship, and subsequent recovery. Conclusion This study suggests that phantom vibration and ringing might be entities that are independent of anxiety or depression during evaluation of stress-associated experiences during medical internships.

Purpose The purpose of cancer staging systems is to accurately predict patient prognosis. The outcome of advanced hepatocellular carcinoma (HCC) depends on both the cancer stage and the extent of liver dysfunction. Many staging systems that include both aspects have been developed. It remains unknown, however, which of these systems is optimal for predicting patient survival. Patients and Methods Patients with advanced HCC treated over a 5-year period at Memorial Sloan-Kettering Cancer Center were identified from an electronic medical record database. Patients with sufficient data for utilization in all staging systems were included. TNM sixth edition, Okuda, Barcelona Clinic Liver Cancer (BCLC), Cancer of the Liver Italian Program (CLIP), Chinese University Prognostic Index (CUPI), Japan Integrated Staging (JIS), and Groupe d'Etude et de Traitement du Carcinome Hepatocellulaire (GETCH) systems were ranked on the basis of their accuracy at predicting survival by using concordance index (c-index). Other independent prognostic variables were also identified. Results Overall, 187 eligible patients were identified and were staged by using the seven staging systems. CLIP, CUPI, and GETCH were the three top-ranking staging systems. BCLC and TNM sixth edition lacked any meaningful prognostic discrimination. Performance status, AST, abdominal pain, and esophageal varices improved the discriminatory ability of CLIP. Conclusion In our selected patient population, CLIP, CUPI, and GETCH were the most informative staging systems in predicting survival in patients with advanced HCC. Prospective validation is required to determine if they can be accurately used to stratify patients in clinical trials and to direct the appropriate need for systemic therapy versus best supportive care. BCLC and TNM sixth edition were not helpful in predicting survival outcome, and their use is not supported by our data. PMID:20458042

Based on the analysis of the requirements of conversation history storage in CPM (Converged IP Messaging) system, a Multi-views storage model and access methods of conversation history are proposed. The storage model separates logical views from physical storage and divides the storage into system managed region and user managed region. It simultaneously supports conversation view, system pre-defined view and user-defined view of storage. The rationality and feasibility of multi-view presentation, the physical storage model and access methods are validated through the implemented prototype. It proves that, this proposal has good scalability, which will help to optimize the physical data storage structure and improve storage performance.
