  1. Three S's of Undergraduate Course Architecture: Compatibilities of Setting, Style and Structure

    Robertson, Patricia R.; Wakeling, Victor

    2018-01-01

    Three separate baseline decisions are recommended when designing an undergraduate course prior to considering any course content. The "Three S" course design decisions include determining (1) the "setting" (on-campus, online or hybrid), (2) the learning "style" (passive or active), and (3) the learning…

    Why regularities in personality can be described with particular dimensions is a basic question in differential psychology. Nonhuman primates can also be characterized in terms of personality structure. Comparative approaches can help reveal phylogenetic constraints and social and ecological patterns associated with the presence or absence of specific personality dimensions. We sought to determine how different personality structures are related to interspecific variation in social style. Specifically, we examined this question in 6 different species of macaques, because macaque social style is well characterized and can be categorized on a spectrum of despotic (Grade 1) versus tolerant (Grade 4) social styles. We derived personality structures from adjectival ratings of Japanese (Macaca fuscata; Grade 1), Assamese (M. assamensis; Grade 2), Barbary (M. sylvanus; Grade 3), Tonkean (M. tonkeana; Grade 4), and crested (M. nigra; Grade 4) macaques and compared these species with rhesus macaques (M. mulatta; Grade 1) whose personality was previously characterized. Using a nonparametric method, fuzzy set analysis, to identify commonalities in personality dimensions across species, we found that all but 1 species exhibited consistently defined Friendliness and Openness dimensions, but that similarities in personality dimensions capturing aggression and social competence reflect similarities in social styles. These findings suggest that social and phylogenetic relationships contribute to the origin, maintenance, and diversification of personality. (c) 2015 APA, all rights reserved.

  3. Perceived parental rearing style in childhood: internal structure and concurrent validity on the Egna Minnen Beträffande Uppfostran--Child Version in clinical settings.

    Penelo, Eva; Viladrich, Carme; Domènech, Josep M

    2010-01-01

    We provide the first validation data of the Spanish version of the Egna Minnen Beträffande Uppfostran--Child Version (EMBU-C) in a clinical context. The EMBU-C is a 41-item self-report questionnaire that assesses perceived parental rearing style in children, comprising 4 subscales (rejection, emotional warmth, control attempts/overprotection, and favoring subjects). The test was administered to a clinical sample of 174 Spanish psychiatric outpatients aged 8 to 12. Confirmatory factor analyses were performed, analyzing the children's reports about their parents' rearing style. The results were almost equivalent for father's and mother's ratings. Confirmatory factor analysis yielded an acceptable fit to data of the 3-factor model when removing the items of the favoring subjects scale (root mean squared error of approximation .73), whereas control attempts scale showed lower values, as in previous studies. The influence of sex (of children and parents) on scale scores was inappreciable and children tended to perceive their parents as progressively less warm as they grew older. As predicted, the scores for rejection and emotional warmth were related to bad relationships with parents, absence of family support, harsh discipline, and lack of parental supervision. The Spanish version of EMBU-C can be used with psychometric guarantees to identify rearing style in psychiatric outpatients because evidences of quality in this setting match those obtained in community samples.

    Full Text Available Excessive smartphone usage has become a highly controversial and substantial worldwide issue. This paper explores the complexities and challenges of smartphone addiction with a particular focus on parenting styles, attachment, and self-regulation. Convenience sampling was used to gather data from 211 university students in Hong Kong (138 females/74 males through their responses to four questionnaires. One structural equation model was formed successfully which indicated that parenting style (authoritative or permissive could be a reasonable predictor of attachment style (secure or dismissive and self-regulation (impulse control or goal setting for smartphone addictions (positive anticipation, withdrawal, cyberspace relationship or overuse. Parenting style was a positive correlate to predict attachment, while the attachment positive correlated to predict self-regulation. Self-regulation was a negative correlate to smartphone addiction. It was revealed that a positive parenting style and positive attachment style could form a significant model with self-regulation and smartphone addiction. Furthermore, secure attachment had higher mediation effect, while impulse control and goal setting behavior had a fair mediation power over influencing addiction tendency. This model helped explore the relationships between smartphone addiction and other constructs in educational psychology. Based on findings, educators can gain insights into how parenting and self-regulation can influence the tendency towards excessive smartphone usage. More educational programs which aim at promoting adequate parenting skills, motivating children through self-regulation and goal setting, is proposed through this study.

    2001-01-01

    The DepUty (dependencies utility) can be classified as a project and process management tool. The main goal of DepUty is to assist by means of source code analysis and graphical representation using UML, in understanding dependencies of sub-systems and packages in CMS Object Oriented software, to understand architectural structure, and to schedule code release in modularised integration. It also allows a new-comer to more easily understand the global structure of CMS software, and to void circular dependencies up-front or re-factor the code, in case it was already too close to the edge of non-maintainability. The authors will discuss the various views DepUty provides to analyse package dependencies, and illustrate both the metrics and style checking facilities it provides

    2010-08-01

    To examine associations between parenting styles, family structure and aspects of adolescent dietary behaviour. Cross-sectional study. Secondary schools in the East Midlands, UK. Adolescents aged 12-16 years (n 328, 57 % boys) completed an FFQ assessing their consumption of fruit, vegetables, unhealthy snacks and breakfast. Adolescents provided information on parental and sibling status and completed a seventeen-item instrument measuring the general parenting style dimensions of involvement and strictness, from which four styles were derived: indulgent, neglectful, authoritarian, authoritative. After controlling for adolescent gender and age, analysis of covariance revealed no significant interactions between parenting style and family structure variables for any of the dietary behaviours assessed. Significant main effects for family structure were observed only for breakfast consumption, with adolescents from dual-parent families (P parent families and those with one or more brother, respectively. Significant main effects for parenting style were observed for all dietary behaviours apart from vegetable consumption. Adolescents who described their parents as authoritative ate more fruit per day, fewer unhealthy snacks per day, and ate breakfast on more days per week than those who described their parents as neglectful. The positive associations between authoritative parenting style and adolescent dietary behaviour transcend family structure. Future research should be food-specific and assess the efficacy of strategies promoting the central attributes of an authoritative parenting style on the dietary behaviours of adolescents from a variety of family structures.

    Full Text Available The present study investigated the relationship between Art and Science students’ learning styles and their ESP reading strategies in academic settings. Learning styles are defined as general orientations learners take toward their learning experiences. This notion has recently obtained attention in the area of language learning. Strategies are also defined as specific behaviours or techniques learners employ towards leaning in order to achieve their learning goals. The strategies chosen are often linked to the individual's learning style. The purpose of this study was to identify Art and Science students’ major learning style preferences and their strategies they employ to tackle their reading materials in ESP courses at Tabriz Islamic Art University. To this end, 313 Art and Science students at Tabriz Islamic Art University answered two self-report questionnaires (PLSPQ and SORS to identify their major and minor learning styles as well as their reading strategies in ESP reading. In order to find any relationship between the students’ preferred learning style (s and their reading strategies in ESP, Pearson Product Moment Coefficient r was used to analyze the participants’ answers to the questionnaires. The results showed that Art students favored Kinesthetic, Auditory, Visual and Tactile learning styles as their major learning styles while Science students showed preference to only Kinesthetic Learning style as their major learning style and other learning styles as their minor ones. It was also found that the most dominant reading strategies both Art and Science students apply in reading their ESP texts was cognitive strategies. Correlational analyses of their major learning styles and their reading strategies are discussed.

  10. Exploring child-feeding style in childcare settings: how might nursery practitioners affect child eating style and weight?

    Elford, L; Brown, A

    2014-04-01

    Although considerable research has explored the role of parents in affecting child eating habits and weight, there has been little consideration of the impact of other key care providers in the early years. A controlling maternal child-feeding style (e.g. use of pressure to eat or restricting certain foods) has been associated with over consumption, fussy eating and weight issue. Conversely, responsive child-feeding styles whereby children are allowed to regulate their own intake but encouraged to eat a range of foods and try new tastes are associated with healthier eating styles and weight. Increasing numbers of preschool children now spend time in day care settings, many for up to fifty hours a week but interactions with caregivers during mealtimes remain unexplored. The aim of the current study was to begin to explore child-feeding styles of nursery practitioners working with children aged 0-5 years. Sixty three nursery practitioners completed an adapted version of the Child Feeding Questionnaire to examine their interactions with children during mealtimes. Themes included pressure to eat, encouragement to eat and use of reward. Typically practitioners reported responsive child-feeding styles with low levels of pressure to eat but high levels of encouragement to try new foods. Use of reward to eat certain foods or as a bribe to modify behaviour was however more common. The findings have important implications for understanding the role of childcare providers in affecting child eating habits and weight. Crown Copyright © 2014. Published by Elsevier Ltd.

    2016-09-01

    Full Text Available The Fushan Depression is a half-graben rifted sub-basin located in the southeast of the Beibuwan Basin, South China Sea. The Paleogene Liushagang sequence is the main hydrocarbon-bearing stratigraphic unit in the sub-basin. Using three-dimensional (3-D seismic data and logging data over the sub-basin, we analyzed structural styles and sedimentary characteristics of the Liushagang sequence. Five types of structural styles were defined: ancient horst, traditional slope, flexure slope-break, faulted slope-break and multiple-stage faults slope, and interpretations for positions, background and development formations of each structural style were discussed. Structural framework across the sub-basin reveals that the most remarkable tectonic setting is represented by the central transfer zone (CTZ which divides the sub-basin into two independent depressions, and two kinds of sequence architectures are summarized: (i the western multi-stage faults slope; (ii the eastern flexure slope break belt. Combined with regional stress field of the Fushan Depression, we got plane combinations of the faults, and finally built up plan distribution maps of structural system for main sequence. Also, we discussed the controlling factors mainly focused on subsidence history and background tectonic activities such as volcanic activity and earthquakes. The analysis of structural styles and tectonic evolution provides strong theoretical support for future prospecting in the Fushan sub-basin and other similar rifted basins of the Beibuwan Basin in South China Sea.

    Effective leadership of healthcare professionals is critical for strengthening quality and integration of care. This study aimed to assess whether there exist an association between different leadership styles and healthcare quality measures. The search was performed in the Medline (National Library of Medicine, PubMed interface) and EMBASE databases for the time period 2004-2015. The research question that guided this review was posed as: "Is there any relationship between leadership style in healthcare settings and quality of care?" Eighteen articles were found relevant to our research question. Leadership styles were found to be strongly correlated with quality care and associated measures. Leadership was considered a core element for a well-coordinated and integrated provision of care, both from the patients and healthcare professionals.

  15. Development of a smart, anti-water polyurethane polymer hair coating for style setting.

    Liu, Y; Liu, Y J; Hu, J; Ji, F L; Lv, J; Chen, S J; Zhu, Y

    2016-06-01

    The goal of this work was to develop a novel polyurethane polymer coating for the surface of the hair that could be used for style setting via the shape memory effect (SME). The features of the films are in accordance with conventional hair styling methods used in the laboratory. In this study, a new polyurethane polymer was synthesized; the morphology and mechanical behaviour of the coated hair were systematically investigated using a scanning electron microscope (SEM) and an Instron 5566 (with a temperature oven). The SME of the hair was tested using a 35-g weight and over five washing and drying cycles. The experimental result shows that the polyurethane polymer has effects on the mechanical behaviour of the hair. It indicates that the fixed shape (at 22°C) and recover rate (at 60°C) of different casted thickness films are similar. And the stress of the film becomes larger with increasing film thickness. Furthermore, the shape memory ability could be endowed with the hair styling using this polymer; the hair fibre could recover to the 65% of its original shape after five cycle deformation by 35 g mass under the heat-treated condition; it could recover its original setting styling even after 5th water washing and drying. The SEM results indicated that the microsurface of the hair is coated with the polymer membrane; it contributes to the shape memory ability of the coated hair to keep and recover to the original setting styling. The styling hair can return to the original hair because the polyurethane polymer can be washed out by water with suitable strength and shampoo totally which does not leave any flake. The polyurethane polymer-based hair setting agent has been developed successfully, and it could be coated evenly on the human hair with good hand feeling and SMEs. The SME is highly related to the quantity of polyurethane polymer solution, and the effect could be improved by increasing the solution quantity. The maximum deformation of the coated hair could

  16. Structural adaptations to diverse fighting styles in sexually selected weapons.

    McCullough, Erin L; Tobalske, Bret W; Emlen, Douglas J

    2014-10-07

    The shapes of sexually selected weapons differ widely among species, but the drivers of this diversity remain poorly understood. Existing explanations suggest weapon shapes reflect structural adaptations to different fighting styles, yet explicit tests of this hypothesis are lacking. We constructed finite element models of the horns of different rhinoceros beetle species to test whether functional specializations for increased performance under species-specific fighting styles could have contributed to the diversification of weapon form. We find that horns are both stronger and stiffer in response to species-typical fighting loads and that they perform more poorly under atypical fighting loads, which suggests weapons are structurally adapted to meet the functional demands of fighting. Our research establishes a critical link between weapon form and function, revealing one way male-male competition can drive the diversification of animal weapons.

    2004-12-01

    We investigated the informational structure of written texts (also in the form of speech transcriptions) using Recurrence Quantification Analysis (RQA). RQA technique provides a quantitative description of text sequences at the orthographic level in terms of structuring, and may be useful for a variety of linguistics-related studies. We used RQA to measure differences in linguistic samples from different subjects. They were divided in subgroups based on personality and culture differences. We used RQA and KRQA (Cross Recurrence) to measure the coupling and synchronization during the conversation (semiotic interaction) of different subjects. We discuss results both for the improvement of methodology and some general implications for neurocognitive science.

  4. Structural Style and Lead Identification, Northern Depobelt, Niger Delta, Nigeria

    Ola, P. S.; Adekoya, J. A.

    2003-01-01

    By interpreting biofacies data, wire line log and grid of 2D seismic sections in an integrated manner in some portions of the northern depobelt, Niger delta, the sequence stratigraphic framework of the area was established. This enabled the structural style and genetic sequences of the area to be inferred. Results showed that the depobelt could be I subdivided into minibasins that trend in a NW SE direction and are bounded by synthetic faults in the proximal end and shale diapers in the distal end. All the exploration wells in the area of study, which were drilled on structural highs and were very close to the synthetic faults, turned out to be dry whereas the synclinal lows that resulted from local deposition of sands of the first genetic sequences in each of the minibasins could contain hydrocarbon. Such areas of synclinal lows are hereby proposed, as lead in this study. The intervals are untested and occur faraway from existing wells. By projection the geochemical data of well Oben-1 in the area suggest that the intervals fall within the oil generative window. Characteristic seismic reflection termination patterns, which are predominantly down laps and on laps suggest existence of structural closure for hydrocarbon accumulation within the synclinal lows. This study therefore recommends a reappraisal of these leads using a more focused 3D seismic study. The northern delta depobelt is less risky and inexpensive for oil exploration and exploitation compared with the offshore Niger delta that is gaining more prominence

  5. Social Spirals through Everyday Group Life: Settings and Group Styles in a Comparative Perspective

    Sebastiano Citroni

    2018-01-01

    Full Text Available Everyday group life is generally neglected in the study of the ongoing shifts affecting voluntary associations. This paper is grounded on a comparative ethnography of three Milanese associations affected by transformations in forms of voluntary participation, repertoires of action, and in their relations with public institutions. The study focuses on group styles and settings to ascertain the role played by everyday group life in shaping the implications of these transformations for the production of inclusive outcomes by the observed associations. The author introduces three different results produced by the studied associations and account for them with the same overall argument, which focus on practices and spaces shaping everyday group life. The main findings illustrate that everyday group life works both as a filter through which transformations produce consequences and also as a site of autonomous elaboration through which associations’ outcomes are made and unmade.

  8. Hierarchical sets: analyzing pangenome structure through scalable set visualizations

    2017-01-01

    Abstract Motivation: The increase in available microbial genome sequences has resulted in an increase in the size of the pangenomes being analyzed. Current pangenome visualizations are not intended for the pangenome sizes possible today and new approaches are necessary in order to convert the increase in available information to increase in knowledge. As the pangenome data structure is essentially a collection of sets we explore the potential for scalable set visualization as a tool for pangenome analysis. Results: We present a new hierarchical clustering algorithm based on set arithmetics that optimizes the intersection sizes along the branches. The intersection and union sizes along the hierarchy are visualized using a composite dendrogram and icicle plot, which, in pangenome context, shows the evolution of pangenome and core size along the evolutionary hierarchy. Outlying elements, i.e. elements whose presence pattern do not correspond with the hierarchy, can be visualized using hierarchical edge bundles. When applied to pangenome data this plot shows putative horizontal gene transfers between the genomes and can highlight relationships between genomes that is not represented by the hierarchy. We illustrate the utility of hierarchical sets by applying it to a pangenome based on 113 Escherichia and Shigella genomes and find it provides a powerful addition to pangenome analysis. Availability and Implementation: The described clustering algorithm and visualizations are implemented in the hierarchicalSets R package available from CRAN (https://cran.r-project.org/web/packages/hierarchicalSets) Contact: thomasp85@gmail.com Supplementary information: Supplementary data are available at Bioinformatics online.

  11. Effect of purified oat β-glucan on fermentation of set-style yogurt mix.

    Singh, Mukti; Kim, Sanghoon; Liu, Sean X

    2012-08-01

    Effect of oat β-glucan on the fermentation of set-style yogurt was investigated by incorporating 0%, 0.1%, 0.2%, 0.3%, 0.4%, and 0.5% of purified oat β-glucan into the yogurt mix. It was found that levels up to 0.3% resulted in yogurts with quality characteristics similar to the control yogurt. Higher levels of β-glucan however retarded the fermentation process with noticeable difference in the characteristics of the yogurt. Examination of the morphologies of yogurt with and without β-glucan revealed that β-glucan formed aggregates with casein micelle and did not form phase-separated domains. This research demonstrated that β-glucan could be added to yogurt up to 0.3%, which meets the nutrient guidelines, to have added nutritional benefits. Yogurt is known for its beneficial effects on human health and nutrition. Yogurt production and consumption is increasing in the United States every year. However, it is lacking in β-glucans, which are recognized for their nutritional importance as functional bioactive ingredients. The main objective was to develop and characterize low-fat yogurts with added β-glucan. This research demonstrated that β-glucan could be added to yogurt up to 0.3%, which meets the nutrient guidelines for added nutritional benefits, without affecting the characteristics of yogurt significantly. This study will benefit the dairy industry by generating new products offering healthy alternatives.

  12. Profiling Perceptual Learning Styles of Chinese as a Second Language Learners in University Settings.

    Sun, Peijian Paul; Teng, Lin Sophie

    2017-12-01

    This study revisited Reid's (1987) perceptual learning style preference questionnaire (PLSPQ) in an attempt to answer whether the PLSPQ fits in the Chinese-as-a-second-language (CSL) context. If not, what are CSL learners' learning styles drawing on the PLSPQ? The PLSPQ was first re-examined through reliability analysis and confirmatory factor analysis (CFA) with 224 CSL learners. The results showed that Reid's six-factor PLSPQ could not satisfactorily explain the CSL learners' learning styles. Exploratory factor analyses were, therefore, performed to explore the dimensionality of the PLSPQ in the CSL context. A four-factor PLSPQ was successfully constructed including auditory/visual, kinaesthetic/tactile, group, and individual styles. Such a measurement model was cross-validated through CFAs with 118 CSL learners. The study not only lends evidence to the literature that Reid's PLSPQ lacks construct validity, but also provides CSL teachers and learners with insightful and practical guidance concerning learning styles. Implications and limitations of the present study are discussed.

  13. Correlation of parenting style and pediatric behavior guidance strategies in the dental setting: preliminary findings.

    Aminabadi, Naser Asl; Farahani, Ramin Mostofi Zadeh

    2008-04-01

    The aim of this study was to investigate the influence of parenting style on the choice of proper behavior guidance strategies in pedodontics. Seventy-two children aged between 4 and 6 years (mean 5.12 years) with carious primary mandibular molars were selected. The Primary Caregivers' Practices Report (PCPR) was used to quantify authoritarian, permissive and authoritative aspects of the caregivers' parenting style. After inferior alveolar nerve block, carious lesions were removed and the teeth were restored using amalgam. The children's behavior during operation was assessed according to the sound, eye, and motor (SEM) scale. Communicative guidance, advance behavior guidance, parental separation, and deferred treatment were used for behavior management. The dominant authoritative score was observed in 50% of parents, permissive in 37.5%, and authoritarian in 12.5%. The mean SEM score in children belonging to authoritative parents was significantly lower than in children of permissive and of authoritarian parents (pparenting style. Advanced behavior guidance (protective stabilization) was applied in 16.7% of cases in the authoritative category and in 100% in the permissive and authoritarian categories. The use of restrictive devices (7.4%) and sedation (3.7%) was limited to the permissive category. Parental separation (40.7%) and deferred treatment (3.7%) were performed only in the permissive category. This study provides preliminary evidence that a child's reaction to restorative dental procedures is influenced by the nature of the caregiver's parenting style.

  15. Style representation in design grammars

    Ahmad, Sumbul; Chase, Scott Curland

    2012-01-01

    The concept of style is relevant for both the analysis and synthesis of designs. New styles are often formed by the adaptation of previous ones based on changes in design criteria and context. A formal characterization of style is given by shape grammars, which describe the compositional rules...... underlying a set of designs. Stylistic change can be modelled by grammar transformations, which allow the transformation of the structure and vocabulary of a grammar that is used to describe a particular style. In order for grammars to be useful beyond a single application, they should have the capability...... to be transformed according to changing design style needs. Issues of formalizing stylistic change necessitate a lucid and formal definition of style in the design language generated by a grammar. Furthermore, a significant aspect of the definition of style is the representation of aesthetic qualities attributed...

  18. Felder-Soloman's Index of Learning Styles: internal consistency, temporal stability, and factor structure.

    Hosford, Charles C; Siders, William A

    2010-10-01

    Strategies to facilitate learning include using knowledge of students' learning style preferences to inform students and their teachers. Aims of this study were to evaluate the factor structure, internal consistency, and temporal stability of medical student responses to the Index of Learning Styles (ILS) and determine its appropriateness as an instrument for medical education. The ILS assesses preferences on four dimensions: sensing/intuitive information perceiving, visual/verbal information receiving, active/reflective information processing, and sequential/global information understanding. Students entering the 2002-2007 classes completed the ILS; some completed the ILS again after 2 and 4 years. Analyses of responses supported the ILS's intended structure and moderate reliability. Students had moderate preferences for sensing and visual learning. This study provides evidence supporting the appropriateness of the ILS for assessing learning style preferences in medical students.

  2. Why style matters - uncertainty and structural interpretation in thrust belts.

    Butler, Rob; Bond, Clare; Watkins, Hannah

    2016-04-01

    Structural complexity together with challenging seismic imaging make for significant uncertainty in developing geometric interpretations of fold and thrust belts. Here we examine these issues and develop more realistic approaches to building interpretations. At all scales, the best tests of the internal consistency of individual interpretations come from structural restoration (section balancing), provided allowance is made for heterogeneity in stratigraphy and strain. However, many existing balancing approaches give misleading perceptions of interpretational risk - both on the scale of individual fold-thrust (trap) structures and in regional cross-sections. At the trap-scale, idealised models are widely cited - fault-bend-fold, fault-propagation folding and trishear. These make entirely arbitrary choices for fault localisation and layer-by-layer deformation: precise relationships between faults and fold geometry are generally invalidated by real-world conditions of stratigraphic variation and distributed strain. Furthermore, subsurface predictions made using these idealisations for hydrocarbon exploration commonly fail the test of drilling. Rarely acknowledged, the geometric reliability of seismic images depends on the assigned seismic velocity model, which in turn relies on geological interpretation. Thus iterative approaches are required between geology and geophysics. The portfolio of commonly cited outcrop analogues is strongly biased to examples that simply conform to idealised models - apparently abnormal structures are rarely described - or even photographed! Insight can come from gravity-driven deep-water fold-belts where part of the spectrum of fold-thrust complexity is resolved through seismic imaging. This imagery shows deformation complexity in fold forelimbs and backlimbs. However, the applicability of these, weakly lithified systems to well-lithified successions (e.g. carbonates) of many foreland thrust belts remains conjectural. Examples of

  5. Factor Structure and Measurement Invariance of the Need-Supportive Teaching Style Scale for Physical Education.

    Liu, Jing-Dong; Chung, Pak-Kwong

    2017-08-01

    The purpose of the current study was to examine the factor structure and measurement invariance of a scale measuring students' perceptions of need-supportive teaching (Need-Supportive Teaching Style Scale in Physical Education; NSTSSPE). We sampled 615 secondary school students in Hong Kong, 200 of whom also completed a follow-up assessment two months later. Factor structure of the scale was examined through exploratory structural equation modeling (ESEM). Further, nomological validity of the NSTSSPE was evaluated by examining the relationships between need-supportive teaching style and student satisfaction of psychological needs. Finally, four measurement models-configural, metric invariance, scalar invariance, and item uniqueness invariance-were assessed using multiple group ESEM to test the measurement invariance of the scale across gender, grade, and time. ESEM results suggested a three-factor structure of the NSTSSPE. Nomological validity was supported, and weak, strong, and strict measurement invariance of the NSTSSPE was evidenced across gender, grade, and time. The current study provides initial psychometric support for the NSTSSPE to assess student perceptions of teachers' need-supportive teaching style in physical education classes.

    Barbuto, John E; Xu, Ye

    2006-02-01

    126 leaders and 624 employees were sampled to test the relationship between sources of motivation and conflict management styles of leaders and how these variables influence effectiveness of leadership. Five sources of motivation measured by the Motivation Sources Inventory were tested-intrinsic process, instrumental, self-concept external, self-concept internal, and goal internalization. These sources of work motivation were associated with Rahim's modes of interpersonal conflict management-dominating, avoiding, obliging, complying, and integrating-and to perceived leadership effectiveness. A structural equation model tested leaders' conflict management styles and leadership effectiveness based upon different sources of work motivation. The model explained variance for obliging (65%), dominating (79%), avoiding (76%), and compromising (68%), but explained little variance for integrating (7%). The model explained only 28% of the variance in leader effectiveness.

    Full Text Available In this article results of the evaluation of leadership styles, brand managers and assessing the potential of employees in a four-star hotel in Poland are presented. The research were based on the Toyota’s leadership model, especially ninth principle of Toyota management and the BOST survey. On the basis of hotel employees answers the dominant leadership style of managers was determined, from the point of view of their degree of interest according to issues related to the quality of service. The statistical analysis of responses was made using the statistical position parameters and whiskers-box plots. The identification of the leadership structure styles was made in analyzed hotel using leadership style maps and various approaches to the analysis of those maps. The correlation analysis and assessment of employees personal characteristics impact on the scores of the factors was made in the features of superiors. Correlative relationship was examined at three levels of significance 1. α = 0.2, 2. α = 0.1, 3. α = 0.05. The analysis showed that PA factor is judged better by women than by men; respondents differ significantly by level of education in the case of YA factor and by age in the case of YA and YB factors and by work experience in the case of YA factor. Workers differ statistically significantly by sex in evaluation of factor YA. Map of superiors brand was created in order to determine the structure of unconditional behavior and of behaviors that support managers. This analysis showed high efficiency of decision managers and their large commitment (simultaneous dominance of managing behavior and support behavior. Personnel BCG matrix was created based on the traditional BCG matrix with the names used normally in the matrix but related to employees. The analysis showed that the majority of hotel workers rated themselves as people with high growth potential but low-effects of their own work.

    Lau, Wendy S Y; Zhou, Xiao-Chun; Lai, Simon M K

    2017-03-01

    Our behaviors are regulated by our perception of the future based on past experiences and knowledge. Children from a disadvantaged background might encounter obstacles more frequently when they plan their future. It is possible that a good relationship with an adult volunteer who provides assistance and guidance in the disadvantaged youth's development may facilitate their future-planning style and career goal setting. The present study investigated the role of a good mentoring relationship in promoting a disadvantaged youth's future-planning style and goal-setting ability. It focused on children from a disadvantaged background who participated in the Child Development Fund (CDF) in Hong Kong. In the study, 187 CDF participants (93 with high mentoring-relationship quality [MRQ] and 94 with low MRQ) and 208 comparison group participants were able to complete all four times of the survey. Repeated-measures analyses of covariance showed that Group main effects were observed for both future-planning style, F(2, 374) = 5.92, p career goal-setting self-efficacy, F(2, 376) = 6.07, p planning style only, F(5.78, 1081.21) = 2.17, p planning style and career goal-setting self-efficacy. Multiple regression analyses revealed that mean MRQ score accounted for 3.9% (p planning style and 4.1% (p career goal-setting self-efficacy, supporting the role of a good mentoring relationship. Mentors have introduced new resources to the disadvantaged youths with high MRQ and have promoted the development of various skills through modeling. © 2017 The Institute of Psychology, Chinese Academy of Sciences and John Wiley & Sons Australia, Ltd.

    Nédélec, Anne; Bowden, Peter

    2015-01-01

    Granites are emblematic rocks developed from a magma that crystallized in the Earth’s crust. They ultimately outcrop at the surface worldwide. This book, translated and updated from the original French edition Pétrologie des Granites (2011) is a modern presentation of granitic rocks from magma genesis to their crystallization at a higher level into the crust. Segregation from the source, magma ascent and shapes of granitic intrusions are also discussed, as well as the eventual formation of hybrid rocks by mingling/mixing processes and the thermomechanical aspects in country rocks around granite plutons. Modern techniques for structural studies of granites are detailed extensively. Granites are considered in their geological spatial and temporal frame, in relation with plate tectonics and Earth history from the Archaean eon. A chapter on granite metallogeny explains how elements of economic interest are concentrated during magma crystallization, and examples of Sn, Cu, F and U ore deposits are presented. Mi...

  13. STYLE - A European project on structural integrity: Progress of the work after 2 Years

    Heussner, Stefan; Nicak, Tomas; Keim, Elisabeth

    2012-01-01

    The purpose of this paper is to present the progress of the work on the EURATOM project STYLE (Structural integrity for lifetime management - non-RPV components). The project focuses on the structural integrity assessment of reactor coolant pressure boundary components (RCPB) relevant to ageing and life time management. The 4-years project started in January 2010 and is now in its third year. Within STYLE realistic failure models for some of the key components will be identified. The range of assessment tools considered will include those for assessment of component failure by advanced fracture mechanics analyses validated on small and large scale experiments, quantification of weld residual stresses by numerical analysis and by measurements, stress corrosion crack initiation and growth effects and assessment of RCPB components (excluding the reactor pressure vessel) under dynamic and seismic loading. Based on theoretical and experimental results, performance assessment and further development of simplified engineering assessment methods (EAM) will be carried out considering both deterministic and probabilistic approaches. Integrity assessment case studies and large scale demonstration experiments will be performed on Mock-ups of safety relevant components. These will include a repair weld in an aged butt-welded austenitic pipe, a dissimilar narrow gap TIG weld (following the EPR design) and a cladded ferritic pipe. Moreover, experiments on specimens and feature test pieces will be carried out to support the large scale Mock-up analyses. The end product of the project ('STYLE TOOLS') will comprise best practice guidelines on the use of advanced tools, on improvement and qualification of EAM as a part of European Leak-before-break (LBB) procedures and on life time management of the integrity of RCPB components in European nuclear power plants. The project is interacting with the European Network of Excellence NUGENIA (former NULIFE). (author)

    2016-02-01

    Few studies have examined different perceptions of stress or explored the positive aspects of well-being among pregnant Chinese women, so there is a need to explore these phenomena in order to fill the research gap. The aim of this study was to examine the relationships among the different perceptions of stress, coping styles, and general well-being using a structural equation modeling approach. We examined a hypothetical model among 755 pregnant Chinese women based on the integration of theoretical models. The Perceived Stress Scale (PSS), the Trait Coping Styles Questionnaire (TCSQ), and the General Well-Being Schedule (GWB) were used to measure perceived stress, coping styles, and general well-being, respectively. A structural equation model showed that positive and negative perceptions of stress significantly influenced positive and negative coping styles, respectively. Different perceptions of stress were significantly associated with general well-being, but different coping styles had no significant effects on general well-being. The model had a good fit to the data (IFI = 0.910, TLI = 0.904, CFI = 0.910, and RMSEA = 0.038). Different perception of stress was able to predict significant differences in coping styles and general well-being.

  17. Culture and affect: the factor structure of the affective style questionnaire and its relation with depression and anxiety among Japanese.

    Ito, Masaya; Hofmann, Stefan G

    2014-09-02

    Affective styles are assumed to be one of the underlying processes of depression and anxiety maintenance. However, little is known about the effect of depression and anxiety and the cultural influence of the factor structure. Here, we examined the cross-cultural validity of the Affective Style Questionnaire and its incremental validity for the influence on depression and anxiety. Affective Style Questionnaire was translated into Japanese using standard back-translation procedure. Japanese university students (N = 1,041) served as participants. Emotion Regulation Questionnaire, Acceptance and Action Questionnaire-II, Toronto Alexithymia Scale, Rumination and Reflection Questionnaire, Brief COPE, Self-Construal Scale, and Hospital Anxiety and Depression Scale were administered. Exploratory and confirmatory factor analyses showed that the Affective Style Questionnaire comprised four factors: Concealing, Adjusting, Holding and Tolerating (CFI = .92, TLI = .90, RMSEA = .07). The measure's convergent and discriminant validity was substantiated by its association with various emotion regulation measures. Regression analyses showed that negative influence of Adjusting, Holding, Reappraisal (β = -.17, -.19, -.30) and positive influence of Suppression (β = .23) were observed on depression. For anxiety, Adjusting and Reappraisal was negatively influenced (β = -.29, and -.18). Reliability and validity of the Affective Style Questionnaire was partly confirmed. Further study is needed to clarify the culturally dependent aspects of affective styles.

    We consider the set of coincidence points for two maps between metric spaces. Cardinality, metric and topological properties of the coincidence set are studied. We obtain conditions which guarantee that this set (a) consists of at least two points; (b) consists of at least n points; (c) contains a countable subset; (d) is uncountable. The results are applied to study the structure of the double point set and the fixed point set for multivalued contractions. Bibliography: 12 titles.

  19. Lipschitz equivalence of self-similar sets with touching structures

    Ruan, Huo-Jun; Wang, Yang; Xi, Li-Feng

    2014-01-01

    Lipschitz equivalence of self-similar sets is an important area in the study of fractal geometry. It is known that two dust-like self-similar sets with the same contraction ratios are always Lipschitz equivalent. However, when self-similar sets have touching structures the problem of Lipschitz equivalence becomes much more challenging and intriguing at the same time. So far, all the known results only cover self-similar sets in R with no more than three branches. In this study we establish results for the Lipschitz equivalence of self-similar sets with touching structures in R with arbitrarily many branches. Key to our study is the introduction of a geometric condition for self-similar sets called substitutable. (paper)

  2. Performance of Arch-Style Road Crossing Structures from Relative Movement Rates of Large Mammals

    A. Z. Andis

    2017-10-01

    Full Text Available In recent decades, an increasing number of highway construction and reconstruction projects have included mitigation measures aimed at reducing wildlife-vehicle collisions and maintaining habitat connectivity for wildlife. The most effective and robust measures include wildlife fences combined with wildlife underpasses and overpasses. The 39 wildlife crossing structures included along a 90 km stretch of US Highway 93 on the Flathead Indian Reservation in western Montana represent one of the most extensive of such projects. We measured movements of large mammal species at 15 elliptical arch-style wildlife underpasses and adjacent habitat between April and November 2015. We investigated if the movements of large mammals through the underpasses were similar to large mammal movements in the adjacent habitat. Across all structures, large mammals (all species combined were more likely to move through the structures than pass at a random location in the surrounding habitat. At the species level, white-tailed deer (Odocoileus virginianus and mule deer (O. hemionus used the underpasses significantly more than could be expected based on their movement through the surrounding habitat. However, carnivorous species such as, black bear (Ursus americanus and coyote (Canis latrans moved through the underpasses in similar numbers compared to the surrounding habitat.

  3. Training set optimization under population structure in genomic selection.

    Isidro, Julio; Jannink, Jean-Luc; Akdemir, Deniz; Poland, Jesse; Heslot, Nicolas; Sorrells, Mark E

    2015-01-01

    Population structure must be evaluated before optimization of the training set population. Maximizing the phenotypic variance captured by the training set is important for optimal performance. The optimization of the training set (TRS) in genomic selection has received much interest in both animal and plant breeding, because it is critical to the accuracy of the prediction models. In this study, five different TRS sampling algorithms, stratified sampling, mean of the coefficient of determination (CDmean), mean of predictor error variance (PEVmean), stratified CDmean (StratCDmean) and random sampling, were evaluated for prediction accuracy in the presence of different levels of population structure. In the presence of population structure, the most phenotypic variation captured by a sampling method in the TRS is desirable. The wheat dataset showed mild population structure, and CDmean and stratified CDmean methods showed the highest accuracies for all the traits except for test weight and heading date. The rice dataset had strong population structure and the approach based on stratified sampling showed the highest accuracies for all traits. In general, CDmean minimized the relationship between genotypes in the TRS, maximizing the relationship between TRS and the test set. This makes it suitable as an optimization criterion for long-term selection. Our results indicated that the best selection criterion used to optimize the TRS seems to depend on the interaction of trait architecture and population structure.

  4. Along-dip variations of structural style in the Somali Basin deep-water fold and thrust belt (East Africa)

    Cruciani, Francesco; Rinaldo Barchi, Massimiliano

    2014-05-01

    Continental passive margins are place of extended slope-failure phenomena, which can lead to the formation of gravity-driven deep-water fold and thrust belts (DW-FTBs), in regions where no far-field compressional stress is active. These giant geological features, which are confined to the sedimentary section, consist of extensional-compressional linked systems detached over a common décollement, generally salt or shales. The continental passive margin of northern Kenya and southern Somalia is an excellent and relatively unexplored site for recognizing and understanding the DW-FTBs originated over a regional shale décollement. In this study we have interpreted a 2D seismic data-set of the 1980s, hosted by Marine Geoscience Data System at Lamont-Doherty Earth Observatory of Columbia University (http://www.marine-geo.org), and recently reprocessed by ENI, in order to investigate the structural style of a DW-FTB developed offshore of northern Kenya and southern Somalia (Somali Basin). This region records the oldest sedimentary section of the Indian Ocean since the breakup of Gondwana began in the Middle-Lower Jurassic separating Madagascar from Africa. From the Upper Cretaceous to at least the Lower Miocene, the margin has been characterized by gravitational collapse leading to the formation of a DW-FTB extending more than 400 km along-strike. The northern portion of the DW-FTB is about 150 km wide, whilst in the southern portion is few tens of km wide. We analysed the northern portion along a regional seismic section. Our study represents the first detailed structural interpretation of this DW-FTB since its discovery in the 1980s. The good quality of the available reprocessed seismic data has allowed us to identify remarkable along-dip variations in the structural style. The basal detachment constantly deepens landward, in agreement with a prevailing gravity-spreading deformation process (as in the case of the Niger Delta). On the seismic data are not visible, as

  5. Structural level set inversion for microwave breast screening

    Irishina, Natalia; Álvarez, Diego; Dorn, Oliver; Moscoso, Miguel

    2010-01-01

    We present a new inversion strategy for the early detection of breast cancer from microwave data which is based on a new multiphase level set technique. This novel structural inversion method uses a modification of the color level set technique adapted to the specific situation of structural breast imaging taking into account the high complexity of the breast tissue. We only use data of a few microwave frequencies for detecting the tumors hidden in this complex structure. Three level set functions are employed for describing four different types of breast tissue, where each of these four regions is allowed to have a complicated topology and to have an interior structure which needs to be estimated from the data simultaneously with the region interfaces. The algorithm consists of several stages of increasing complexity. In each stage more details about the anatomical structure of the breast interior is incorporated into the inversion model. The synthetic breast models which are used for creating simulated data are based on real MRI images of the breast and are therefore quite realistic. Our results demonstrate the potential and feasibility of the proposed level set technique for detecting, locating and characterizing a small tumor in its early stage of development embedded in such a realistic breast model. Both the data acquisition simulation and the inversion are carried out in 2D

  7. [Association of family dynamic structure and parental rearing style with male larcenists].

    Zheng, Yu; Liu, Xie-he

    2010-11-01

    To explore the association of parental rearing style and family dynamic structure with male larcenists. A questionnaire survey was undertaken in 280 male imprisoned larcenists and 420 healthy controls with a General Information Questionnaire and EMBU (Egna Minnen Beträlffande Uppfostran). Statistically significant differences were found between the two groups in the following items: 'only child in the family', 'not lived with father before age 5', 'father died', 'mother died', 'both parents died', 'parents divorced', 'lived with father only (mother absence) before age 5', 'adult with father alive (mother died)' and 'adult with mother alive (father died)'. The two groups also experienced significant differences in 'emotional warmth', 'severe punishment', 'over-intervention from both parents', 'favored child from mother', 'father rejection' and 'father over-protection'. Men with single father (mother absence) before age 5 and those who have experienced death of any parents, 'emotional warmth', 'severe punishment', 'over-intervention from both parents', 'favored child from mother', 'father rejection' and 'father over-protection' are more likely to commit theft crime.

    Full Text Available A graph structure is a useful tool in solving the combinatorial problems in different areas of computer science and computational intelligence systems. In this paper, we apply the concept of bipolar fuzzy sets to graph structures. We introduce certain notions, including bipolar fuzzy graph structure (BFGS, strong bipolar fuzzy graph structure, bipolar fuzzy Ni-cycle, bipolar fuzzy Ni-tree, bipolar fuzzy Ni-cut vertex, and bipolar fuzzy Ni-bridge, and illustrate these notions by several examples. We study ϕ-complement, self-complement, strong self-complement, and totally strong self-complement in bipolar fuzzy graph structures, and we investigate some of their interesting properties.

  15. Basement Structure and Styles of Active Tectonic Deformation in Central Interior Alaska

    Dixit, N.; Hanks, C.

    2017-12-01

    Central Interior Alaska is one of the most seismically active regions in North America, exhibiting a high concentration of intraplate earthquakes approximately 700 km away from the southern Alaska subduction zone. Based on increasing seismological evidence, intraplate seismicity in the region does not appear to be uniformly distributed, but concentrated in several discrete seismic zones, including the Nenana basin and the adjacent Tanana basin. Recent seismological and neotectonics data further suggests that these seismic zones operate within a field of predominantly pure shear driven primarily by north-south crustal shortening. Although the location and magnitude of the seismic activity in both basins are well defined by a network of seismic stations in the region, the tectonic controls on intraplate earthquakes and the heterogeneous nature of Alaska's continental interior remain poorly understood. We investigated the current crustal architecture and styles of tectonic deformation of the Nenana and Tanana basins using existing geological, geophysical and geochronological datasets. The results of our study demonstrate that the basements of the basins show strong crustal heterogeneity. The Tanana basin is a relatively shallow (up to 2 km) asymmetrical foreland basin with its southern, deeper side controlled by the northern foothills of the central Alaska Range. Northeast-trending strike-slip faults within the Tanana basin are interpreted as a zone of clockwise crustal block rotation. The Nenana basin has a fundamentally different geometry; it is a deep (up to 8 km), narrow transtensional pull-apart basin that is deforming along the left-lateral Minto Fault. This study identifies two distinct modes of tectonic deformation in central Interior Alaska at present, and provides a basis for modeling the interplay between intraplate stress fields and major structural features that potentially influence the generation of intraplate earthquakes in the region.

  16. Parental feeding styles and adolescents' healthy eating habits. Structure and correlates of a Costa Rican questionnaire.

    Monge-Rojas, Rafael; Smith-Castro, Vanesa; Colon-Ramos, Uriyoán; Garita-Arce, Carlos; Sánchez-López, Marta; Chinnock, Anne

    2010-10-01

    This study designed and validated a questionnaire aimed at examining parental feeding styles to encourage healthy eating habits among Costa Rican adolescents. Adolescents (n=133; mean age 15.4 years), and their parents, participated in the study. The parents completed a parental feeding style questionnaire, and the adolescents completed 3-day food records. Confirmatory factor analyses suggest four distinct parental feeding styles, (a) verbal encouragement of healthy eating behaviors; (b) use of verbal sanctions to indirectly control the intake of healthy food; (c) direct control of access to and intake of food; and (d) use of food to regulate emotions and behavior. There were no correlations between dietary intake and the verbal encouragement of healthy eating behaviors, but there were significant negative correlations between (1) "the use of verbal sanctions to indirectly control the intake of healthy food", and the consumption of fruit and vegetable, of calcium, iron, vitamin B6 and folic acid intake, and (2) between the "direct control of access to and intake of food" and fast food consumption and total carbohydrates intake. The use of food to regulate emotions and behavior was positively correlated with high energy-dense food consumption. Stratification of the data shows significant differences by gender in the correlations between parental feeding style and dietary intake. Understanding parental feeding styles in a Latin American context is a first step in helping researchers develops culturally-appropriate parenting intervention/prevention strategies to encourage healthy eating behaviors during adolescence.

  17. Family structure, family functioning and adolescent well-being: the transcendent influence of parental style.

    McFarlane, A H; Bellissimo, A; Norman, G R

    1995-07-01

    This study assessed the association between parental style, family functioning and adolescent well being, contrasting intact families with those of changed configuration. Eight hundred and one grade 10 general level teenagers in 11 high schools of a single educational system were the subjects. Results indicated that the configuration of the family was not the key determinant of effectiveness of family functioning. Instead the style of parenting turned out to be the main determinant of both family functioning and well being of the adolescents. While both "parents" were judged to have contributed to these outcomes cross gender effects were found.

  2. Entrepreneurs` Cognitive and Decision Making Styles

    Mahmoud Motvaseli

    2015-12-01

    Full Text Available The main purpose of this study is to explore the relation between decision-making styles which are measured by the General decision-making style (GDMS test and information processing styles which are often termed cognitive styles and are, in this study, measured by Cognitive Style Inventory. The authors directed a survey research on 162 Iranian students. Structural equation modeling techniques were used to measure the impact of cognitive styles on decision-making styles. The authors found that cognitive styles have a positive impact on decision-making styles. In spite of the abundant research on factors that affect decision-making styles, few researches have tested the relationship between cognitive styles and decision-making styles. This study examines the impact of cognitive styles on decision-making styles in Iran. This study, like most research paper studies, cannot easily be generalized. Furthermore, the results of this study could be affected by economic conditions.

  5. Topology optimization of hyperelastic structures using a level set method

    Chen, Feifei; Wang, Yiqiang; Wang, Michael Yu; Zhang, Y. F.

    2017-12-01

    Soft rubberlike materials, due to their inherent compliance, are finding widespread implementation in a variety of applications ranging from assistive wearable technologies to soft material robots. Structural design of such soft and rubbery materials necessitates the consideration of large nonlinear deformations and hyperelastic material models to accurately predict their mechanical behaviour. In this paper, we present an effective level set-based topology optimization method for the design of hyperelastic structures that undergo large deformations. The method incorporates both geometric and material nonlinearities where the strain and stress measures are defined within the total Lagrange framework and the hyperelasticity is characterized by the widely-adopted Mooney-Rivlin material model. A shape sensitivity analysis is carried out, in the strict sense of the material derivative, where the high-order terms involving the displacement gradient are retained to ensure the descent direction. As the design velocity enters into the shape derivative in terms of its gradient and divergence terms, we develop a discrete velocity selection strategy. The whole optimization implementation undergoes a two-step process, where the linear optimization is first performed and its optimized solution serves as the initial design for the subsequent nonlinear optimization. It turns out that this operation could efficiently alleviate the numerical instability and facilitate the optimization process. To demonstrate the validity and effectiveness of the proposed method, three compliance minimization problems are studied and their optimized solutions present significant mechanical benefits of incorporating the nonlinearities, in terms of remarkable enhancement in not only the structural stiffness but also the critical buckling load.

  6. Structured assessment of microsurgery skills in the clinical setting.

    Chan, WoanYi; Niranjan, Niri; Ramakrishnan, Venkat

    2010-08-01

    Microsurgery is an essential component in plastic surgery training. Competence has become an important issue in current surgical practice and training. The complexity of microsurgery requires detailed assessment and feedback on skills components. This article proposes a method of Structured Assessment of Microsurgery Skills (SAMS) in a clinical setting. Three types of assessment (i.e., modified Global Rating Score, errors list and summative rating) were incorporated to develop the SAMS method. Clinical anastomoses were recorded on videos using a digital microscope system and were rated by three consultants independently and in a blinded fashion. Fifteen clinical cases of microvascular anastomoses performed by trainees and a consultant microsurgeon were assessed using SAMS. The consultant had consistently the highest scores. Construct validity was also demonstrated by improvement of SAMS scores of microsurgery trainees. The overall inter-rater reliability was strong (alpha=0.78). The SAMS method provides both formative and summative assessment of microsurgery skills. It is demonstrated to be a valid, reliable and feasible assessment tool of operating room performance to provide systematic and comprehensive feedback as part of the learning cycle.

  7. Global self-esteem and method effects: competing factor structures, longitudinal invariance, and response styles in adolescents.

    Urbán, Róbert; Szigeti, Réka; Kökönyei, Gyöngyi; Demetrovics, Zsolt

    2014-06-01

    The Rosenberg Self-Esteem Scale (RSES) is a widely used measure for assessing self-esteem, but its factor structure is debated. Our goals were to compare 10 alternative models for the RSES and to quantify and predict the method effects. This sample involves two waves (N =2,513 9th-grade and 2,370 10th-grade students) from five waves of a school-based longitudinal study. The RSES was administered in each wave. The global self-esteem factor with two latent method factors yielded the best fit to the data. The global factor explained a large amount of the common variance (61% and 46%); however, a relatively large proportion of the common variance was attributed to the negative method factor (34 % and 41%), and a small proportion of the common variance was explained by the positive method factor (5% and 13%). We conceptualized the method effect as a response style and found that being a girl and having a higher number of depressive symptoms were associated with both low self-esteem and negative response style, as measured by the negative method factor. Our study supported the one global self-esteem construct and quantified the method effects in adolescents.

  8. Longitudinal tests of competing factor structures for the Rosenberg Self-Esteem Scale: traits, ephemeral artifacts, and stable response styles.

    Marsh, Herbert W; Scalas, L Francesca; Nagengast, Benjamin

    2010-06-01

    Self-esteem, typically measured by the Rosenberg Self-Esteem Scale (RSE), is one of the most widely studied constructs in psychology. Nevertheless, there is broad agreement that a simple unidimensional factor model, consistent with the original design and typical application in applied research, does not provide an adequate explanation of RSE responses. However, there is no clear agreement about what alternative model is most appropriate-or even a clear rationale for how to test competing interpretations. Three alternative interpretations exist: (a) 2 substantively important trait factors (positive and negative self-esteem), (b) 1 trait factor and ephemeral method artifacts associated with positively or negatively worded items, or (c) 1 trait factor and stable response-style method factors associated with item wording. We have posited 8 alternative models and structural equation model tests based on longitudinal data (4 waves of data across 8 years with a large, representative sample of adolescents). Longitudinal models provide no support for the unidimensional model, undermine support for the 2-factor model, and clearly refute claims that wording effects are ephemeral, but they provide good support for models positing 1 substantive (self-esteem) factor and response-style method factors that are stable over time. This longitudinal methodological approach has not only resolved these long-standing issues in self-esteem research but also has broad applicability to most psychological assessments based on self-reports with a mix of positively and negatively worded items.

  10. Style and creativity in design

    Chan, Chiu-Shui

    2015-01-01

    This book looks at causative reasons behind creative acts and stylistic expressions. It explores how creativity is initiated by design cognition and explains relationships between style and creativity. The book establishes a new cognitive theory of style and creativity in design and provides designers with insights into their own cognitive processes and styles of thinking, supporting a better understanding of the qualities present in their own design.  An explanation of the nature of design cognition begins this work, with a look at how design knowledge is formulated, developed, structured and utilized, and how this utilization triggers style and creativity. The author goes on to review historical studies of style, considering a series of psychological experiments relating to the operational definition, degree, measurement, and creation of style. The work conceptually summarizes the recognition of individual style in products, as well as the creation of such styles as a process before reviewing studies on cr...

    to explore the nature of leadership styles used by the nursing management team, as perceived by nurses working at the bedside. leadership style is related to job satisfaction, staff retention, costs, and quality of care. The leadership styles of managers can be crucial in the healthcare setting, but very few studies have focused on them. the study employed qualitative methodology, involving 35 nurses working in different specialties of a medical city in Saudi Arabia. Data collection consisted of completing demographic and professional information and a semi-structured interview using open-ended questions. a phenomenologic-hermeneutic approach was used to identify major themes. the findings showed that participants described four types of leadership styles: relational leadership, preferential leadership, communication chain leadership, and ineffectual leadership. the leadership style employed by nurse managers has a major impact on nurses' satisfaction, turnover, and the quality of patient care they deliver.

  19. A Research on the Structure of Intelligence and Creativity, and Creativity Style

    Feyzullah Şahin

    2015-06-01

    Full Text Available The relationship between intelligence and creativity may be linked to the difficulties in defining and measuring methodology. Threshold theory is one of the theories which is used to explain the relationship between them. The aim of this study is to investigate the structures which the creative thinking ability of the gifted students and their intellectual structure is grouped and the structure which their creative thinking ability are alone. Data was gathered using Wechsler Intelligence Scale for Children-R and Torrance Thinking Creativity Test (TTCT. Confirmatory factor analyses were conducted with data from 278 gifted primary school students which contained the grade range of 1 to 3. The results indicate that the TTCT subscores consist of 2 factors called adaptive and innovative rather than a single factor. Besides, the results of the analyses provide support that creativity and intelligence are independent from each other.

  20. Effects of Bullying Experience on Psychological Well-Being Mediated by Conflict Management Styles and Psychological Empowerment among Nursing Students in Clinical Placement: A Structural Equation Modeling Approach.

    Ren, Liping; Kim, Hyunli

    2017-10-01

    This study aimed to test a proposed structural equation model in which bullying experience, conflict management styles and psychological empowerment predict psychological well-being among Chinese nursing students in clinical placement. Three hundred and sixty-six nursing students recruited from five hospitals in J city and Y city were assessed with self-report questionnaires on bullying experience, conflict management styles, psychological empowerment and psychological well-being including depression, self-esteem, and academic major satisfaction. Data were analyzed using SPSS version 20.0 and AMOS version 22.0. The evaluation parameters included the comparative fit index at .90, the goodness of fit index at .93, the root mean square error of approximation at .07, and χ²/df ratio at 2.66, indicating that the proposed structural equation model provided a good fit to the data. Experience of being bullied during clinical placement, conflict management styles and psychological empowerment explained 93.0% of the variance and had significant effects on psychological well-being, with conflict management styles and psychological empowerment mediating the association between bullying and psychological well-being. The findings indicated that mediation by conflict management styles and psychological empowerment alleviated the negative influence of bullying on psychological well-being. To limit bullying and its negative effects, development of effective guidelines to deal with bullying will be a critical tool for both Chinese nursing students and their instructors. Further research should incorporate conflict management styles and psychological empowerment into the specific intervention strategies for handling bullying behaviors among nursing students and staff nurses and promoting nursing students' psychological well-being. © 2017 Korean Society of Nursing Science

  3. The Logical Structures of Comparison: Its Forms, Styles, Problems, and the Role of History in Social and Political Research

    Fabio de Nardis

    2014-11-01

    Full Text Available All political sciences share the same logic and methods as the empirical social sciences and therefore produce perceptive knowledge. Empirical knowledge is based on a specific kind of observation driven by a set of theoretically developed concepts related to clearly observable social phenomena. Not all the concepts, however, are readily amenable to observational terms. We usually need to proceed to their operationalization. The formulation and the operational definition of the empirical concepts does not exhaust the analytic process. It is also necessary to observe how the phenomenon occurs in the reality, proceeding to classification or typological constructions and, sometimes, to the production of multi-dimensional models. Only after this process will the formulation of hypotheses be possible. They will later be verified through the use of methods of empirical control. The most frequently used activity in political sociology is comparison, which is the main method of any social science according to most scholars. Comparison can be carried out both among a certain number of cases or within a single case by comparing it in its historical development. The temporal dimension becomes crucial when one wishes to produce historically rooted generalizations and theories, therefore confined to a spatial and temporal dimension. Before proceeding with the comparison we must make sure that the cases selected are actually comparable and that they possess at least one property in common. The objective of this paper is therefore to describe forms and styles of comparison within the logic of social and political sciences

  4. Reefs of the Jurassic-Cretaceous west Atlantic margin : an overview of settings, types, facies trends, depositional styles and terminations (with reservoir implications)

    Eliuk, L.S. [GeoTours Consulting Inc., Calgary, AB (Canada)

    2005-07-01

    In the past 40 years, approximately 20 exploratory wells have been drilled in the Jurassic-Cretaceous Abenaki Formation near-margin carbonate sequences off the Atlantic coast. These include the pioneer wells drilled in the 1970s offshore Nova Scotia, a mid-1980s group including 3 Baltimore Canyon wells in the United States, and those following EnCana's Deep Panuke 1998 gas discovery offshore Nova Scotia. A comparison of these wells has revealed 2 margin settings over deep basement highs versus prograded carbonates, 3 reef-reef mound/slope types, and an overall vertical facies trend that reveals an upward progression from microbial-rich slope beds to shallower forereef to reef and reef-flat beds initially rich in coralline sponges, followed by more microsolenid corals and bioeroded stormreworked coral-rich and oncolitic debris beds up to oolitic shoals. The top of carbonate bank sequences may be replaced gradually by shallow-water siliciclastics near deltaic depocentres or abruptly by deeper-water sponge-reef-derived beds. Smaller-scale similar flooding and shoaling patterns exist within this overall style that allow sequence or parasequence subdivision in Nova Scotia following an initial oolitic flooding event immediately above the Misaine shale. The association of deltas and reef termination suggests drowning by nutrient poisoning. The mid-Mesozoic biotas appear more robust by living in close proximity to siliciclastics. Being at the carbonate shelf margin and in a non-argillaceous shallow water reef-associated facies would appear to be necessary requirements for gas-bearing reservoir development in the Abenaki, but they are not sufficient. Originally porous oolitic grainstones are tight in areas where they are deeply buried in the Panuke area. Siliciclastic burial influenced the limestone cementation, resulting in potential stratigraphic trapping where offset by subsurface dolomitization and leaching fed by fractures or faults in coarser reef

  6. Mediterranean-style diet effect on the structural properties of the erythrocyte cell membrane of hypertensive patients: the Prevencion con Dieta Mediterranea Study.

    Barceló, Francisca; Perona, Javier S; Prades, Jesús; Funari, Sérgio S; Gomez-Gracia, Enrique; Conde, Manuel; Estruch, Ramon; Ruiz-Gutiérrez, Valentina

    2009-11-01

    A currently ongoing randomized trial has revealed that the Mediterranean diet, rich in virgin olive oil or nuts, reduces systolic blood pressure in high-risk cardiovascular patients. Here, we present a structural substudy to assess the effect of a Mediterranean-style diet supplemented with nuts or virgin olive oil on erythrocyte membrane properties in 36 hypertensive participants after 1 year of intervention. Erythrocyte membrane lipid composition, structural properties of reconstituted erythrocyte membranes, and serum concentrations of inflammatory markers are reported. After the intervention, the membrane cholesterol content decreased, whereas that of phospholipids increased in all of the dietary groups; the diminishing cholesterol:phospholipid ratio could be associated with an increase in the membrane fluidity. Moreover, reconstituted membranes from the nuts and virgin olive oil groups showed a higher propensity to form a nonlamellar inverted hexagonal phase structure that was related to an increase in phosphatidylethanolamine lipid class. These data suggest that the Mediterranean-style diet affects the lipid metabolism that is altered in hypertensive patients, influencing the structural membrane properties. The erythrocyte membrane modulation described provides insight in the structural bases underlying the beneficial effect of a Mediterranean-style diet in hypertensive subjects.

  10. Strong Migration Limit for Games in Structured Populations: Applications to Dominance Hierarchy and Set Structure

    Dhaker Kroumi

    2015-09-01

    Full Text Available In this paper, we deduce a condition for a strategy S1 to be more abundant on average at equilibrium under weak selection than another strategy S2 in a population structured into a finite number of colonies of fixed proportions as the population size tends to infinity. It is assumed that one individual reproduces at a time with some probability depending on the payoff received in pairwise interactions within colonies and between colonies and that the offspring replaces one individual chosen at random in the colony into which the offspring migrates. It is shown that an expected weighted average equilibrium frequency of S1 under weak symmetric strategy mutation between S1 and S2 is increased by weak selection if an expected weighted payoff of S1 near neutrality exceeds the corresponding expected weighted payoff of S2. The weights are given in terms of reproductive values of individuals in the different colonies in the neutral model. This condition for S1 to be favoured by weak selection is obtained from a strong migration limit of the genealogical process under neutrality for a sample of individuals, which is proven using a two-time scale argument. The condition is applied to games between individuals in colonies with linear or cyclic dominance and between individuals belonging to groups represented by subsets of a given set.

  12. [Parenting styles].

    Torío López, Susana; Peña Calvo, José Vicente; Inda Caro, Mercedes

    2008-02-01

    Parental educational styles constitute one of the key elements of family socialization. The aim of the present essay is to present the results of a research project carried out in the Principality of Asturias (Spain) among 2,965 families with children of infant and primary-school age (5-8 years old). This research attempts to analyse, among other aspects, parental behaviour tendencies in child upbringing. The analysis of the results obtained allows us to: 1) identify the most common attitudinal and behavioural tendencies of parents in the upbringing of their children; 2) determine how many people have a well defined parental style, and delimit their socio-educational characteristics. Lastly, we consider the need to change some parental behaviour patterns and stress the importance of family education programmes, with the aim of promoting appropriate parenting models and modifying or improving current practices.

  13. Structural evolution and tectonic style of the Tunisian central Atlas; role of inherited faults in compressive tectonics (Ghoualguia anticline)

    Briki, Haithem; Ahmadi, Riadh; Smida, Rabiaa; Rekhiss, Farhat

    2018-04-01

    Geological mapping, field cross sections, structural analyses and new subsurface data were used to characterize the geometry and tectonic setting of the Ghoualguia structure, which is an E-W-trending anticline located between the Kalaa Khasba and Rouhia troughs of the central Tunisian Atlas. The results show an important NE-SW extensional phase during the Mesozoic, as demonstrated by synsedimentary normal faults (NW-SE and E-W) and thickness variations. In the Aouled Mdoua area, the absence of Paleocene-Eocene rocks indicates that the eastern and western parts of the Ghoualguia structure were separated by high topography. In addition, the angular unconformity observed between the Upper Cretaceous unit (Abiod Fm.) and the upper Eocene series (Souar Fm.) provide evidence of a tilted-block structure delineated by North-South faults. A major compressional phase during the middle to late Miocene created various detachment levels that originated mainly in the Triassic and Cretaceous deposits. Faults were reactivated as thrust and strike-slip faults, creating fault-related fold structures. In the core of the Ghoualguia fold, an original S-dipping normal fault underwent reverse movement as a back thrust. Fault-slip data indicate that the area records a major NE-SW extensional phase that took place during the late Miocene and Pliocene. A balanced cross section provides insight into the existence of two main detachment levels rooted in the Triassic (depth ± 6 km) and the lower Cretaceous (depth ± 2.5 km). The balanced cross section highlights a shortening of about 2.5 km along cross section and 1.5 km in the central part of the Ghoualguia anticline. This work underlines the predominant role of the inherited Mesozoic structures during the evolution of the Atlassic range and their influence on the geometry of the central Tunisian atlas.

  14. Monitoring of Students' Interaction in Online Learning Settings by Structural Network Analysis and Indicators.

    Ammenwerth, Elske; Hackl, Werner O

    2017-01-01

    Learning as a constructive process works best in interaction with other learners. Support of social interaction processes is a particular challenge within online learning settings due to the spatial and temporal distribution of participants. It should thus be carefully monitored. We present structural network analysis and related indicators to analyse and visualize interaction patterns of participants in online learning settings. We validate this approach in two online courses and show how the visualization helps to monitor interaction and to identify activity profiles of learners. Structural network analysis is a feasible approach for an analysis of the intensity and direction of interaction in online learning settings.

  16. Effect of basement structure and salt tectonics on deformation styles along strike: An example from the Kuqa fold-thrust belt, West China

    Neng, Yuan; Xie, Huiwen; Yin, Hongwei; Li, Yong; Wang, Wei

    2018-04-01

    The Kuqa fold-thrust belt (KFTB) has a complex thrust-system geometry and comprises basement-involved thrusts, décollement thrusts, triangle zones, strike-slip faults, transpressional faults, and pop-up structures. These structures, combined with the effects of Paleogene salt tectonics and Paleozoic basement uplift form a complex structural zone trending E-W. Interpretation and comprehensive analysis of recent high-quality seismic data, field observations, boreholes, and gravity data covering the KFTB has been performed to understand the characteristics and mechanisms of the deformation styles along strike. Regional sections, fold-thrust system maps of the surface and the sub-salt layer, salt and basement structure distribution maps have been created, and a comprehensive analysis of thrust systems performed. The results indicate that the thrust-fold system in Paleogene salt range can be divided into five segments from east to west: the Kela-3, Keshen, Dabei, Bozi, and Awate segments. In the easternmost and westernmost parts of the Paleogene salt range, strike-slip faulting and basement-involved thrusting are the dominant deformation styles, as basement uplift and the limits of the Cenozoic evaporite deposit are the main controls on deformation. Salt-core detachment fold-thrust systems coincide with areas of salt tectonics, and pop-up, imbricate, and duplex structures are associated with the main thrust faults in the sub-salt layer. Distribution maps of thrust systems, basement structures, and salt tectonics show that Paleozoic basement uplift controlled the Paleozoic foreland basin morphology and the distribution of Cenozoic salt in the KFTB, and thus had a strong influence on the segmented structural deformation and evolution of the fold-thrust belt. Three types of transfer zone are identified, based on the characteristics of the salt layer and basement uplift, and the effects of these zones on the fault systems are evaluated. Basement uplift and the boundary of

    Ashford Paul

    2012-03-01

    Full Text Available Abstract Background Protein structures provide a valuable resource for rational drug design. For a protein with no known ligand, computational tools can predict surface pockets that are of suitable size and shape to accommodate a complementary small-molecule drug. However, pocket prediction against single static structures may miss features of pockets that arise from proteins' dynamic behaviour. In particular, ligand-binding conformations can be observed as transiently populated states of the apo protein, so it is possible to gain insight into ligand-bound forms by considering conformational variation in apo proteins. This variation can be explored by considering sets of related structures: computationally generated conformers, solution NMR ensembles, multiple crystal structures, homologues or homology models. It is non-trivial to compare pockets, either from different programs or across sets of structures. For a single structure, difficulties arise in defining particular pocket's boundaries. For a set of conformationally distinct structures the challenge is how to make reasonable comparisons between them given that a perfect structural alignment is not possible. Results We have developed a computational method, Provar, that provides a consistent representation of predicted binding pockets across sets of related protein structures. The outputs are probabilities that each atom or residue of the protein borders a predicted pocket. These probabilities can be readily visualised on a protein using existing molecular graphics software. We show how Provar simplifies comparison of the outputs of different pocket prediction algorithms, of pockets across multiple simulated conformations and between homologous structures. We demonstrate the benefits of use of multiple structures for protein-ligand and protein-protein interface analysis on a set of complexes and consider three case studies in detail: i analysis of a kinase superfamily highlights the

  19. Male and Female Ministers: Comparing Roman Catholic and Methodist Deacons on Personality Structure, Religious Beliefs, and Leadership Styles.

    Ferrari, Joseph R

    2017-03-01

    Christian deacons (50 Roman Catholic; 50 Methodist) self-reported their personality, religiosity, and leadership attributes, plus social desirability tendencies. There were no significant correlates between social desirability and any of these self-reported variables. Results also found no significant differences across Christian denominations on personality dimensions, religious and spirituality beliefs, or leadership styles. Also, there were no significant differences in self-reported personality, religiosity, or leadership among Catholic male deacons with Methodist female deacons only ( n = 43). Taken together, in the present exploratory study across denomination and gender, Christian deacons view themselves similarly in personality, religiosity, and overall leadership characteristics.

    Objective To examine the small antral follicle (SAF) cohort in ovaries of adult rhesus monkeys following consumption of a western-style diet (WSD), with or without chronically elevated androgen levels since before puberty. Design Cholesterol or testosterone (T; n=6/group) implants were placed subcutaneously in female rhesus macaques beginning at 1 yr of age (pre-pubertal), with addition of a WSD (high fat/fructose) at 5.5 yrs (menarche ~2.6 yrs). Ovaries were collected at 7 yrs of age. One ovary/female was embedded in paraffin for morphological and immunohistochemical analyses. The SAFs (Ovaries of adult monkeys consuming a standard macaque diet (low in fats and sugars) were obtained at similar stages of the menstrual cycle and used as controls for all analyses. Setting National primate research center Animals Adult, female rhesus monkeys (Macaca mulatta) Interventions None Main outcome measures Histological analyses, SAF counts and morphology, protein localization and abundance in SAFs, transcriptome in SAFs (mRNAs) Results Compared to controls, consumption of a WSD, with and without T treatment, increased the numbers of SAFs per ovary, due to the presence of more atretic follicles. Numbers of granulosa cells expressing cellular proliferation markers (pRb and pH3) was greater in healthy SAFs, while numbers of cells expressing the cell cycle inhibitor (p21) was higher in atretic SAFs. Intense CYP17A1 staining was observed in the theca cells of SAFs from WSD+/− T groups, compared to controls. Microarray analyses of the transcriptome in SAFs isolated from WSD and WSD+T treated females and controls consuming a standard diet, identified 1944 genes whose mRNA levels changed ≥2-fold among the three groups. Further analyses identified several gene pathways altered by WSD and/or WSD+T associated with steroid, carbohydrate and lipid metabolism, plus ovarian processes. Alterations in levels of several SAF mRNAs are similar to those observed in follicular cells from women

    2014-08-01

    Full Text Available The present study examined the relationships between dispositional approach and avoidance motives, humor styles, and happiness. In keeping with previous research, approach motives and the two positive humor styles (self-enhancing and affiliative positively correlated with happiness, whereas avoidance motives and the two negative humor styles (self-defeating and aggressive negatively correlated with happiness. Also, we found support for three new hypotheses. First, approach motives correlated positively with self-enhancing and affiliative humor styles. Second, avoidance motives correlated positively with self-defeating humor style, and third, the positive relationship between approach motives and happiness was mediated by self-enhancing humor style.

    The targets of the Structural GenomiX (SGX) bacterial genomics project were proteins conserved in multiple prokaryotic organisms with no obvious sequence homolog in the Protein Data Bank of known structures. The outcome of this work was 80 structures, covering 60 unique sequences and 49 different genes. Experimental phase determination from proteins incorporating Se-Met was carried out for 45 structures with most of the remainder solved by molecular replacement using members of the experimentally phased set as search models. An automated tool was developed to deposit these structures in the Protein Data Bank, along with the associated X-ray diffraction data (including refined experimental phases) and experimentally confirmed sequences. BLAST comparisons of the SGX structures with structures that had appeared in the Protein Data Bank over the intervening 3.5 years since the SGX target list had been compiled identified homologs for 49 of the 60 unique sequences represented by the SGX structures. This result indicates that, for bacterial structures that are relatively easy to express, purify, and crystallize, the structural coverage of gene space is proceeding rapidly. More distant sequence-structure relationships between the SGX and PDB structures were investigated using PDB-BLAST and Combinatorial Extension (CE). Only one structure, SufD, has a truly unique topology compared to all folds in the PDB. Copyright 2005 Wiley-Liss, Inc.

  4. Structural Studies of the SET Domain from RIZ1 Tumor Suppressor

    Briknarova, Klara; Zhou, Xinliang; Satterthwait, Arnold C.; Hoyt, David W.; Ely, Kathryn R.; Huang, Shi

    2008-02-15

    Histone lysine methyltransferases (HKMTs) are involved in regulation of chromatin structure, and, as such, are important for longterm gene activation and repression that is associated with cell memory and establishment of cell-type specific transcriptional programs. Most HKMTs contain a SET domain, which is responsible for their catalytic activity. RIZ1 is a transcription regulator and tumor suppressor that catalyzes methylation of lysine 9 of histone H3 and contains a rather distinct SET domain. Similar SET domains, sometimes refererred to as PR (PRDI-BF1 and RIZ1 homology) domains, are also found in other proteins including Blimp-1/PRDI-BF1, MDS1-EVI1 and Meisetz. We determined the solution structure of the PR domain from RIZ1 and characterized its interaction with S-adenosyl homocysteine (SAH) and a peptide from histone H3. Despite low sequence identity with canonical SET domains, the PR domain displays a typical SET fold including a pseudo-knot at the C-terminus. The N-flanking sequence of RIZ1 PR domain adopts a novel conformation and interacts closely with the SET fold. The C-flanking sequence contains an α-helix that exhibits higher mobility than the SET fold and points away from the protein face that harbors active site in other SET domains. Residues that interact with the methylation cofactor in SET domains are not conserved in RIZ1 or other PR domains, and the SET fold of RIZ1 does not bind SAH. However, the PR domain of RIZ1 interacts specifically with a synthetic peptide comprising residues 1-20 of histone H3.

The analysis begins with the definition of management style as concept followed by an exposition of its main functions and its fundamental dimensions. Then, the paper presents the methodology used to verify how these dimensions appear among managers as well as the results obtained during the fieldwork. Such methodology includes the achievement of in-depth interviews, with the help of a questionnaire of semi-structured questions, and the descriptive analysis of qualitative and quantitative information obtained from those interviews. The revision of these aspects enriches the study of management at the advertising agencies since it contributes to understand why certain actions have as a consequence one particular kind of relationship between directors and collaborators or another.

  8. Mapping topographic structure in white matter pathways with level set trees.

    Brian P Kent

    Full Text Available Fiber tractography on diffusion imaging data offers rich potential for describing white matter pathways in the human brain, but characterizing the spatial organization in these large and complex data sets remains a challenge. We show that level set trees--which provide a concise representation of the hierarchical mode structure of probability density functions--offer a statistically-principled framework for visualizing and analyzing topography in fiber streamlines. Using diffusion spectrum imaging data collected on neurologically healthy controls (N = 30, we mapped white matter pathways from the cortex into the striatum using a deterministic tractography algorithm that estimates fiber bundles as dimensionless streamlines. Level set trees were used for interactive exploration of patterns in the endpoint distributions of the mapped fiber pathways and an efficient segmentation of the pathways that had empirical accuracy comparable to standard nonparametric clustering techniques. We show that level set trees can also be generalized to model pseudo-density functions in order to analyze a broader array of data types, including entire fiber streamlines. Finally, resampling methods show the reliability of the level set tree as a descriptive measure of topographic structure, illustrating its potential as a statistical descriptor in brain imaging analysis. These results highlight the broad applicability of level set trees for visualizing and analyzing high-dimensional data like fiber tractography output.

  9. Improvement of training set structure in fusion data cleaning using Time-Domain Global Similarity method

    Liu, J.; Lan, T.; Qin, H.

    2017-01-01

    Traditional data cleaning identifies dirty data by classifying original data sequences, which is a class-imbalanced problem since the proportion of incorrect data is much less than the proportion of correct ones for most diagnostic systems in Magnetic Confinement Fusion (MCF) devices. When using machine learning algorithms to classify diagnostic data based on class-imbalanced training set, most classifiers are biased towards the major class and show very poor classification rates on the minor class. By transforming the direct classification problem about original data sequences into a classification problem about the physical similarity between data sequences, the class-balanced effect of Time-Domain Global Similarity (TDGS) method on training set structure is investigated in this paper. Meanwhile, the impact of improved training set structure on data cleaning performance of TDGS method is demonstrated with an application example in EAST POlarimetry-INTerferometry (POINT) system.

  10. What it Takes to Get Passed On: Message Content, Style, and Structure as Predictors of Retransmission in the Boston Marathon Bombing Response.

    Jeannette Sutton

    Full Text Available Message retransmission is a central aspect of information diffusion. In a disaster context, the passing on of official warning messages by members of the public also serves as a behavioral indicator of message salience, suggesting that particular messages are (or are not perceived by the public to be both noteworthy and valuable enough to share with others. This study provides the first examination of terse message retransmission of official warning messages in response to a domestic terrorist attack, the Boston Marathon Bombing in 2013. Using messages posted from public officials' Twitter accounts that were active during the period of the Boston Marathon bombing and manhunt, we examine the features of messages that are associated with their retransmission. We focus on message content, style, and structure, as well as the networked relationships of message senders to answer the question: what characteristics of a terse message sent under conditions of imminent threat predict its retransmission among members of the public? We employ a negative binomial model to examine how message characteristics affect message retransmission. We find that, rather than any single effect dominating the process, retransmission of official Tweets during the Boston bombing response was jointly influenced by various message content, style, and sender characteristics. These findings suggest the need for more work that investigates impact of multiple factors on the allocation of attention and on message retransmission during hazard events.

  12. Uniqueness of the joint measurement and the structure of the set of compatible quantum measurements

    Guerini, Leonardo; Terra Cunha, Marcelo

    2018-04-01

    We address the problem of characterising the compatible tuples of measurements that admit a unique joint measurement. We derive a uniqueness criterion based on the method of perturbations and apply it to show that extremal points of the set of compatible tuples admit a unique joint measurement, while all tuples that admit a unique joint measurement lie in the boundary of such a set. We also provide counter-examples showing that none of these properties are both necessary and sufficient, thus completely describing the relation between the joint measurement uniqueness and the structure of the compatible set. As a by-product of our investigations, we completely characterise the extremal and boundary points of the set of general tuples of measurements and of the subset of compatible tuples.

  13. Upper-Lower Bounds Candidate Sets Searching Algorithm for Bayesian Network Structure Learning

    Guangyi Liu

    2014-01-01

    Full Text Available Bayesian network is an important theoretical model in artificial intelligence field and also a powerful tool for processing uncertainty issues. Considering the slow convergence speed of current Bayesian network structure learning algorithms, a fast hybrid learning method is proposed in this paper. We start with further analysis of information provided by low-order conditional independence testing, and then two methods are given for constructing graph model of network, which is theoretically proved to be upper and lower bounds of the structure space of target network, so that candidate sets are given as a result; after that a search and scoring algorithm is operated based on the candidate sets to find the final structure of the network. Simulation results show that the algorithm proposed in this paper is more efficient than similar algorithms with the same learning precision.

  14. A synthesis of mineralization styles and geodynamic settings of the Paleozoic and Mesozoic metallic ore deposits in the Altay Mountains, NW China

    Yang, Fuquan; Geng, Xinxia; Wang, Rui; Zhang, Zhixin; Guo, Xuji

    2018-06-01

    The Altay Mountains within the Xinjiang region of northwestern China hosts major metallic ore deposits. Here we review the geological characteristics, metallogenic features and tectonic settings of these deposits. The metallic ore deposits in the Altay Mountains occur mainly within four regions: North Altay, Central Altay, South Altay and Erqis. We recognize seven types of metallic ore deposits in the Altay Mountains: VMS, submarine volcanogenic iron, magmatic, skarn, pegmatite, hydrothermal vein (Cu-Zn, Fe) and orogenic gold. Among these types, the VMS, pegmatite, orogenic gold and skarn deposits are the most common. Most of the rare metal pegmatite deposits are distributed in Central Altay, with only a few in South Altay. The VMS, submarine volcanogenic type iron and skarn-type deposits are distributed in South Altay, whereas the orogenic-type gold deposits are distributed in the Erqis Fault belt. The hydrothermal vein-type deposits occur in the Erqis Fault belt and Chonghu'er Basin in South Altay. Magmatic-type deposits are mostly in the Erqis Fault belt and Central Altay. Based on isotopic age data, the VMS, submarine volcanogenic-type Fe and skarn-type Cu, Pb, Zn, Fe mineralization occurred during Early-Middle Devonian (∼410-377 Ma), orogenic-type Au, magmatic-type Cu-Ni, and a small number of skarn-type Fe, hydrothermal vein-type Cu-Zn, pegmatite-type rare-metal deposits in Early-Middle Permian (293-261 Ma), pegmatite-type rare-metal deposits, few skarn-type Fe deposit in Early-Middle Triassic (248-232 Ma), and dominantly represented by pegmatite-type rare-metal deposits in Late Triassic-Early Jurassic (223-180 Ma). The metallic ore deposits in the Altay Mountains formed in various tectonic settings, such as the Early-Middle Devonian continental arc and oceanic island arc, Early-Middle Permian post-collisional extensional setting, and Triassic-Early Jurassic intracontinental setting.

  15. Optimal structural inference of signaling pathways from unordered and overlapping gene sets.

    Acharya, Lipi R; Judeh, Thair; Wang, Guangdi; Zhu, Dongxiao

    2012-02-15

    A plethora of bioinformatics analysis has led to the discovery of numerous gene sets, which can be interpreted as discrete measurements emitted from latent signaling pathways. Their potential to infer signaling pathway structures, however, has not been sufficiently exploited. Existing methods accommodating discrete data do not explicitly consider signal cascading mechanisms that characterize a signaling pathway. Novel computational methods are thus needed to fully utilize gene sets and broaden the scope from focusing only on pairwise interactions to the more general cascading events in the inference of signaling pathway structures. We propose a gene set based simulated annealing (SA) algorithm for the reconstruction of signaling pathway structures. A signaling pathway structure is a directed graph containing up to a few hundred nodes and many overlapping signal cascades, where each cascade represents a chain of molecular interactions from the cell surface to the nucleus. Gene sets in our context refer to discrete sets of genes participating in signal cascades, the basic building blocks of a signaling pathway, with no prior information about gene orderings in the cascades. From a compendium of gene sets related to a pathway, SA aims to search for signal cascades that characterize the optimal signaling pathway structure. In the search process, the extent of overlap among signal cascades is used to measure the optimality of a structure. Throughout, we treat gene sets as random samples from a first-order Markov chain model. We evaluated the performance of SA in three case studies. In the first study conducted on 83 KEGG pathways, SA demonstrated a significantly better performance than Bayesian network methods. Since both SA and Bayesian network methods accommodate discrete data, use a 'search and score' network learning strategy and output a directed network, they can be compared in terms of performance and computational time. In the second study, we compared SA and

  16. 1H and 15N NMR assignment and solution structure of the SH3 domain of spectrin: Comparison of unrefined and refined structure sets with the crystal structure

    Blanco, Francisco J.; Ortiz, Angel R.; Serrano, Luis

    1997-01-01

    The assignment of the 1 H and 15 Nnuclear magnetic resonance spectra of the Src-homology region 3 domain of chicken brain α-spectrin has been obtained. A set of solution structures has been determined from distance and dihedral angle restraints,which provide a reasonable representation of the protein structure in solution, as evaluated by a principal component analysis of the global pairwise root-mean-square deviation (rmsd) in a large set of structures consisting of the refined and unrefined solution structures and the crystal structure. The solution structure is well defined, with a lower degree of convergence between the structures in the loop regions than in the secondary structure elements. The average pairwise rmsd between the 15 refined solution structures is 0.71 ± 0.13 A for the backbone atoms and 1.43 ± 0.14 A for all heavy atoms. The solution structure is basically the same as the crystal structure. The average rmsd between the 15 refined solution structures and the crystal structure is 0.76 A for the backbone atoms and 1.45 ± 0.09 A for all heavy atoms. There are, however, small differences probably caused by intermolecular contacts in the crystal structure

  17. Pre-set extrusion bioprinting for multiscale heterogeneous tissue structure fabrication.

    2018-06-06

    Recent advances in three-dimensional bioprinting technology have led to various attempts in fabricating human tissue-like structures. However, current bioprinting technologies have limitations for creating native tissue-like structures. To resolve these issues, we developed a new pre-set extrusion bioprinting technique that can create heterogeneous, multicellular, and multimaterial structures simultaneously. The key to this ability lies in the use of a precursor cartridge that can stably preserve a multimaterial with a pre-defined configuration that can be simply embedded in a syringe-based printer head. The multimaterial can be printed and miniaturized through a micro-nozzle without conspicuous deformation according to the pre-defined configuration of the precursor cartridge. Using this system, we fabricated heterogeneous tissue-like structures such as spinal cords, hepatic lobule, blood vessels, and capillaries. We further obtained a heterogeneous patterned model that embeds HepG2 cells with endothelial cells in a hepatic lobule-like structure. In comparison with homogeneous and heterogeneous cell printing, the heterogeneous patterned model showed a well-organized hepatic lobule structure and higher enzyme activity of CYP3A4. Therefore, this pre-set extrusion bioprinting method could be widely used in the fabrication of a variety of artificial and functional tissues or organs.

  18. Consistent structures and interactions by density functional theory with small atomic orbital basis sets.

    Grimme, Stefan; Brandenburg, Jan Gerit; Bannwarth, Christoph; Hansen, Andreas

    2015-08-07

    A density functional theory (DFT) based composite electronic structure approach is proposed to efficiently compute structures and interaction energies in large chemical systems. It is based on the well-known and numerically robust Perdew-Burke-Ernzerhoff (PBE) generalized-gradient-approximation in a modified global hybrid functional with a relatively large amount of non-local Fock-exchange. The orbitals are expanded in Ahlrichs-type valence-double zeta atomic orbital (AO) Gaussian basis sets, which are available for many elements. In order to correct for the basis set superposition error (BSSE) and to account for the important long-range London dispersion effects, our well-established atom-pairwise potentials are used. In the design of the new method, particular attention has been paid to an accurate description of structural parameters in various covalent and non-covalent bonding situations as well as in periodic systems. Together with the recently proposed three-fold corrected (3c) Hartree-Fock method, the new composite scheme (termed PBEh-3c) represents the next member in a hierarchy of "low-cost" electronic structure approaches. They are mainly free of BSSE and account for most interactions in a physically sound and asymptotically correct manner. PBEh-3c yields good results for thermochemical properties in the huge GMTKN30 energy database. Furthermore, the method shows excellent performance for non-covalent interaction energies in small and large complexes. For evaluating its performance on equilibrium structures, a new compilation of standard test sets is suggested. These consist of small (light) molecules, partially flexible, medium-sized organic molecules, molecules comprising heavy main group elements, larger systems with long bonds, 3d-transition metal systems, non-covalently bound complexes (S22 and S66×8 sets), and peptide conformations. For these sets, overall deviations from accurate reference data are smaller than for various other tested DFT methods

  2. Bioalerts: a python library for the derivation of structural alerts from bioactivity and toxicity data sets.

    Cortes-Ciriano, Isidro

    2016-01-01

    Assessing compound toxicity at early stages of the drug discovery process is a crucial task to dismiss drug candidates likely to fail in clinical trials. Screening drug candidates against structural alerts, i.e. chemical fragments associated to a toxicological response prior or after being metabolized (bioactivation), has proved a valuable approach for this task. During the last decades, diverse algorithms have been proposed for the automatic derivation of structural alerts from categorical toxicity data sets. Here, the python library bioalerts is presented, which comprises functionalities for the automatic derivation of structural alerts from categorical (dichotomous), e.g. toxic/non-toxic, and continuous bioactivity data sets, e.g. [Formula: see text] or [Formula: see text] values. The library bioalerts relies on the RDKit implementation of the circular Morgan fingerprint algorithm to compute chemical substructures, which are derived by considering radial atom neighbourhoods of increasing bond radius. In addition to the derivation of structural alerts, bioalerts provides functionalities for the calculation of unhashed (keyed) Morgan fingerprints, which can be used in predictive bioactivity modelling with the advantage of allowing for a chemically meaningful deconvolution of the chemical space. Finally, bioalerts provides functionalities for the easy visualization of the derived structural alerts.

  3. Implicit leadership theories in applied settings: factor structure, generalizability, and stability over time.

    Epitropaki, Olga; Martin, Robin

    2004-04-01

    The present empirical investigation had a 3-fold purpose: (a) to cross-validate L. R. Offermann, J. K. Kennedy, and P. W. Wirtz's (1994) scale of Implicit Leadership Theories (ILTs) in several organizational settings and to further provide a shorter scale of ILTs in organizations; (b) to assess the generalizability of ILTs across different employee groups, and (c) to evaluate ILTs' change over time. Two independent samples were used for the scale validation (N1 = 500 and N2 = 439). A 6-factor structure (Sensitivity, Intelligence, Dedication, Dynamism, Tyranny, and Masculinity) was found to most accurately represent ELTs in organizational settings. Regarding the generalizability of ILTs, although the 6-factor structure was consistent across different employee groups, there was only partial support for total factorial invariance. Finally, evaluation of gamma, beta, and alpha change provided support for ILTs' stability over time.

    A set of structural mimics of the [Fe]-hydrogenase active site comprising all the group VIII metals, viz., [M(2-NHC(O)C 5 H 4 N)(CO) 2 (2-S-C 5 H 4 N)], has been synthesized. They exist as a mixture of isomers in solution, and the relative stability of the isomers depends on the nature of the metal and the substituent at the 6-position of the pyridine ligand.

  5. Development of a set of process and structure indicators for palliative care: the Europall project

    2012-11-01

    Full Text Available Abstract Background By measuring the quality of the organisation of palliative care with process and structure quality indicators (QIs, patients, caregivers and policy makers are able to monitor to what extent recommendations are met, like those of the council of the WHO on palliative care and guidelines. This will support the implementation of public programmes, and will enable comparisons between organisations or countries. Methods As no European set of indicators for the organisation of palliative care existed, such a set of QIs was developed. An update of a previous systematic review was made and extended with more databases and grey literature. In two project meetings with practitioners and experts in palliative care the development process of a QI set was finalised and the QIs were categorized in a framework, covering the recommendations of the Council of Europe. Results The searches resulted in 151 structure and process indicators, which were discussed in steering group meetings. Of those QIs, 110 were eligible for the final framework. Conclusions We developed the first set of QIs for the organisation of palliative care. This article is the first step in a multi step project to identify, validate and pilot QIs.

    2012-04-01

    To determine the feasibility, the cluster design effect and the variance and minimal clinical importance difference in the primary outcome in a pilot study of a structured approach to goal-setting. A cluster randomized controlled trial. Inpatient rehabilitation facilities. People who were admitted to inpatient rehabilitation following stroke who had sufficient cognition to engage in structured goal-setting and complete the primary outcome measure. Structured goal elicitation using the Canadian Occupational Performance Measure. Quality of life at 12 weeks using the Schedule for Individualised Quality of Life (SEIQOL-DW), Functional Independence Measure, Short Form 36 and Patient Perception of Rehabilitation (measuring satisfaction with rehabilitation). Assessors were blinded to the intervention. Four rehabilitation services and 41 patients were randomized. We found high values of the intraclass correlation for the outcome measures (ranging from 0.03 to 0.40) and high variance of the SEIQOL-DW (SD 19.6) in relation to the minimally importance difference of 2.1, leading to impractically large sample size requirements for a cluster randomized design. A cluster randomized design is not a practical means of avoiding contamination effects in studies of inpatient rehabilitation goal-setting. Other techniques for coping with contamination effects are necessary.

  7. Stratigraphy and structural setting of Upper Cretaceous Frontier Formation, western Centennial Mountains, southwestern Montana and southeastern Idaho

    Dyman, T.S.; Tysdal, R.G.; Perry, W.J.; Nichols, D.J.; Obradovich, J.D.

    2008-01-01

    Stratigraphic, sedimentologic, and palynologic data were used to correlate the Frontier Formation of the western Centennial Mountains with time-equivalent rocks in the Lima Peaks area and other nearby areas in southwestern Montana. The stratigraphic interval studied is in the middle and upper parts (but not uppermost) of the formation based on a comparison of sandstone petrography, palynologic age data, and our interpretation of the structure using a seismic line along the frontal zone of the Centennial Mountains and the adjacent Centennial Valley. The Frontier Formation is comprised of sandstone, siltstone, mudstone, limestone, and silty shale in fluvial and coastal depositional settings. A distinctive characteristic of these strata in the western Centennial Mountains is the absence of conglomerate and conglomeratic sandstone beds. Absence of conglomerate beds may be due to lateral facies changes associated with fluvial systems, a distal fining of grain size, and the absence of both uppermost and lower Frontier rocks in the study area. Palynostratigraphic data indicate a Coniacian age for the Frontier Formation in the western Centennial Mountains. These data are supported by a geochronologic age from the middle part of the Frontier at Lima Peaks indicating a possible late Coniacian-early Santonian age (86.25 ?? 0.38 Ma) for the middle Frontier there. The Frontier Formation in the western Centennial Mountains is comparable in age and thickness to part of the Frontier at Lima Peaks. These rocks represent one of the thickest known sequences of Frontier strata in the Rocky Mountain region. Deposition was from about 95 to 86 Ma (middle Cenomanian to at least early Santonian), during which time, shoreface sandstone of the Telegraph Creek Formation and marine shale of the Cody Shale were deposited to the east in the area now occupied by the Madison Range in southwestern Montana. Frontier strata in the western Centennial Mountains are structurally isolated from other

    Zawadzki, Robert J.; Fuller, Alfred R.; Zhao, Mingtao; Wiley, David F.; Choi, Stacey S.; Bower, Bradley A.; Hamann, Bernd; Izatt, Joseph A.; Werner, John S.

    2006-02-01

    The acquisition speed of current FD-OCT (Fourier Domain - Optical Coherence Tomography) instruments allows rapid screening of three-dimensional (3D) volumes of human retinas in clinical settings. To take advantage of this ability requires software used by physicians to be capable of displaying and accessing volumetric data as well as supporting post processing in order to access important quantitative information such as thickness maps and segmented volumes. We describe our clinical FD-OCT system used to acquire 3D data from the human retina over the macula and optic nerve head. B-scans are registered to remove motion artifacts and post-processed with customized 3D visualization and analysis software. Our analysis software includes standard 3D visualization techniques along with a machine learning support vector machine (SVM) algorithm that allows a user to semi-automatically segment different retinal structures and layers. Our program makes possible measurements of the retinal layer thickness as well as volumes of structures of interest, despite the presence of noise and structural deformations associated with retinal pathology. Our software has been tested successfully in clinical settings for its efficacy in assessing 3D retinal structures in healthy as well as diseased cases. Our tool facilitates diagnosis and treatment monitoring of retinal diseases.

  11. Metallogeny of the Gold Quadrilateral: style and characteristics of epithermal - subvolcanic mineralized structures, South Apuseni Mts., Romania

    S̡erban-Nicolae Vlad

    2004-04-01

    Full Text Available The Romanian territory contains numerous ore deposits mined since pre-Roman times. An assessment of historical gold production of the Gold Quadri-lateral (GQ yielded a total estimate of 55.7 Moz of gold throughout an area of 2400 km2. Interpreted in terms of mineralization density this is 23,208 oz of gold/ km2. The geological setting of the GQ is represented mainly by Tertiary (14.7 My to 7.4 My calc-alkaline volcano-plutonic complexes of intermediate character in sedimentary basins of molasse type. These basins are tectonically controlled by NW-SE lineation across early Alpine magmatic products, i.e. subduction related Jurassic-Lower Cretaceous igneous association (island arc ophiolites and granitoids and Upper Cretaceous igneous association (banatites. The Tertiary magmatism is associated with extensional tectonics caused by NE escape of the Pannonian region during Upper Oligocene-Lower Miocene times. As a result of tectono-magmatic and mineralization-alteration characteristics, two metallogenetical types were separated in the GQ, i.e. calc-alkaline andesitic (CAM and sub-alkaline rhyodacitic (SRM. Both develop almost entirely low-sulfidation type of Au epithermal mineralization. However, two subtypes, -rich in sulfide (2-7% and -poor in sulfide (7-20% were delineated and correlated with CAM type and SRM type respectively. Furthermore, CAM is connected at deeper levels with Cu-Au+/-Mo porphyry systems in contrast with SRM, which is a non-porphyry environment. The Brad-Săcărâmb district contains mainly CAM type andesitic structures. It is a porphyry environment with epithermal low-sulfidation-rich sulfide vein halo (Barza, Troiţa-Bolcana deposits. However, a few SRM type patterns, such as Măgura Ţebii, Băiţa-Crăciuneşti and Săcărâmb, deposits exhibit Au-Ag-Te low-sulfidation-poor sulfide epithermal vein halo. The Zlatna-Stănija district exhibits similar characteristics, with Au-Ag+/-Pb, Zn veins in Cu-Au subvolcanic

  12. Managing Information Uncertainty in Wave Height Modeling for the Offshore Structural Analysis through Random Set

    Keqin Yan

    2017-01-01

    Full Text Available This chapter presents a reliability study for an offshore jacket structure with emphasis on the features of nonconventional modeling. Firstly, a random set model is formulated for modeling the random waves in an ocean site. Then, a jacket structure is investigated in a pushover analysis to identify the critical wave direction and key structural elements. This is based on the ultimate base shear strength. The selected probabilistic models are adopted for the important structural members and the wave direction is specified in the weakest direction of the structure for a conservative safety analysis. The wave height model is processed in a P-box format when it is used in the numerical analysis. The models are applied to find the bounds of the failure probabilities for the jacket structure. The propagation of this wave model to the uncertainty in results is investigated in both an interval analysis and Monte Carlo simulation. The results are compared in context of information content and numerical accuracy. Further, the failure probability bounds are compared with the conventional probabilistic approach.

    The purpose of this study was to evaluate the factor structure and the reliability of the French versions of the Identity Style Inventory (ISI-3) and the Utrecht-Management of Identity Commitments Scale (U-MICS) in a sample of college students (N = 457, 18-25 years old). Confirmatory factor analyses confirmed the hypothesized three-factor solution…

  14. Identification of individual coherent sets associated with flow trajectories using Coherent Structure Coloring

    Schlueter-Kuck, Kristy; Dabiri, John

    2017-11-01

    In recent years, there has been a proliferation of techniques that aim to characterize fluid flow kinematics on the basis of Lagrangian trajectories of collections of tracer particles. Most of these techniques depend on presence of tracer particles that are initially closely-spaced, in order to compute local gradients of their trajectories. In many applications, the requirement of close tracer spacing cannot be satisfied, especially when the tracers are naturally occurring and their distribution is dictated by the underlying flow. Moreover, current methods often focus on determination of the boundaries of coherent sets, whereas in practice it is often valuable to identify the complete set of trajectories that are coherent with an individual trajectory of interest. We extend the concept of Coherent Structure Coloring to achieve identification of the coherent set associated with individual Lagrangian trajectories. This algorithm is proven successful in identifying coherent structures of varying complexities in canonical unsteady flows. Importantly, although the method is demonstrated here in the context of fluid flow kinematics, the generality of the approach allows for its potential application to other unsupervised clustering problems in dynamical systems. This work was supported by the Department of Defense (DoD) through the National Defense Science & Engineering Graduate Fellowship (NDSEG) Program.

    HCCR TBM (Test Blanket Module) set is consist of 4-TBM sub module, one blanket manifold (BM), a shield, and 4-key, which has a function of a connection between BM and the shield. And it shall be installed in the equatorial port No.18 of ITER inside the vacuum vessel directly facing the plasma and shall be cooled by a high-temperature helium coolant. In addition, the HCCR TBM-set safety classification follows the ITER (international thermonuclear reactor) safety importance class (SIC) criteria, and satisfies a design requirement according to RCC-MRx. In this study, some of load combination (LC) analysis for the structure integrity of TBM set were carried out based on the reference. And the LC results showed that they satisfied the design requirement. The material of TBM-set was used from the reference, and RCC-MRx for the stress analysis. In this study, the load combination results were met a design requirement. But some load combination case gave a higher maximum stress value than a design requirement and in these case the stress breakdown analysis according to RCC-MRx was performed, and the result were satisfied the design requirement.

  16. Toward a new conception of conceptions: Interplay of talk, gestures, and structures in the setting

    Givry, Damien; Roth, Wolff-Michael

    2006-12-01

    Most studies about students' conceptions and conceptual change are based exclusively on the analysis language, which is treated as a tool to make private contents of the mind public to researchers. Following recent studies that focused on (a) language and discursive practice and (b) the pragmatics of communication that draws on talk, gestures, and semiotic resources in the setting, we propose a redefinition of the nature of conception. Conceptions are understood as the dialectical relation of simultaneously available speech, gestures, and contextual structures that cannot be reduced to verbal rendering because gestures and contextual structures constitute different modalities in the communication. Drawing on data collected during a physics unit about gas taught in French tenth grade classrooms, we show why an appropriate account of conceptions requires: (a) gestures simultaneously produced with talk; and (b) identification of the relevant structures in the setting used by the participants as meaning-making (semiotic) resources. We propose to: (a) reconceptualize the notion of conception as consisting of a dialectical unit of all relevant semiotic (meaning-making) resources publicly made available by a speaker (talk, gesture, context); and (b) consider conceptual change through the temporal evolution of the dialectical unit defined in this manner.

    2010-07-01

    Full Text Available Design curricula and all core design studio courses are prepared for performance attainment by giving theoretical and professional training. However students’ performance may be affected by both the constraints set on a design problem, and their learning styles. This study explores the performance of interior architectural students in relation to their learning styles (as proposed by Kolb’s Experiential Learning Theory, and different types of constraints set on design problems. Design performance, measured as conceptual development, form and spatial configuration, structural innovation and ergonomics, and craftsmanship, was found to change throughout the two bipolar continuum of the learning cycle with regard to two design conditions characterized by different types of constraint use.

  18. Reading Processes and Parenting Styles.

    Carreteiro, Rui Manuel; Justo, João Manuel; Figueira, Ana Paula

    2016-08-01

    Home literacy environment explains between 12 and 18.5 % of the variance of children's language skills. Although most authors agree that children whose parents encourage them to read tend to develop better and earlier reading skills, some authors consider that the impact of family environment in reading skills is overvalued. Probably, other variables of parent-child relationship, like parenting styles, might be relevant for this field. Nevertheless, no previous studies on the effect of parenting styles in literacy have been found. To analyze the role of parenting styles in the reading processes of children. Children's perceptions of parenting styles contribute significantly to the explanation of statistical variance of children's reading processes. 110 children (67 boys and 43 girls), aged between 7 and 11 years (M [Formula: see text] 9.22 and SD [Formula: see text] 1.14) from Portuguese schools answered to a socio-demographic questionnaire. To assess reading processes it was administered the Portuguese adaptation (Figueira et al. in press) of Bateria de Avaliação dos Processos Leitores-Revista (PROLEC-R). To assess the parenting styles Egna Minnen av Barndoms Uppfostran-parents (EMBU-P) and EMBU-C (children version) were administered. According to multiple hierarchical linear regressions, individual factors contribute to explain all reading tests of PROLEC-R, while family factors contribute to explain most of these tests. Regarding parenting styles, results evidence the explanatory power about grammatical structures, sentence comprehension and listening. Parenting styles have an important role in the explanation of higher reading processes (syntactic and semantic) but not in lexical processes, focused by main theories concerning dyslexia.

  20. Structure Optimal Design of Electromagnetic Levitation Load Reduction Device for Hydroturbine Generator Set

    Qingyan Wang

    2015-01-01

    Full Text Available Thrust bearing is one part with the highest failure rate in hydroturbine generator set, which is primarily due to heavy axial load. Such heavy load often makes oil film destruction, bearing friction, and even burning. It is necessary to study the load and the reduction method. The dynamic thrust is an important factor to influence the axial load and reduction design of electromagnetic device. Therefore, in the paper, combined with the structure features of vertical turbine, the hydraulic thrust is analyzed accurately. Then, take the turbine model HL-220-LT-550, for instance; the electromagnetic levitation load reduction device is designed, and its mathematical model is built, whose purpose is to minimize excitation loss and total quality under the constraints of installation space, connection layout, and heat dissipation. Particle swarm optimization (PSO is employed to search for the optimum solution; finally, the result is verified by finite element method (FEM, which demonstrates that the optimized structure is more effective.

  1. Style in Music

    Dannenberg, Roger B.

    Because music is not objectively descriptive or representational, the subjective qualities of music seem to be most important. Style is one of the most salient qualities of music, and in fact most descriptions of music refer to some aspect of musical style. Style in music can refer to historical periods, composers, performers, sonic texture, emotion, and genre. In recent years, many aspects of music style have been studied from the standpoint of automation: How can musical style be recognized and synthesized? An introduction to musical style describes ways in which style is characterized by composers and music theorists. Examples are then given where musical style is the focal point for computer models of music analysis and music generation.

  3. In regard to Levi-Strauss’s "motive of oblivion". Structure of disturbed communication and styles of thoughts in transitory Serbia

    Dragana Antonijević

    2016-02-01

    Full Text Available This paper starts with Levi-Strauss’s semantic concept that consists of oblivion, misunderstanding, indiscretion and nostalgia. Through his analysis of North American and Greek myths, Levi-Strauss concluded that "semantic filed of oblivion" has an important meaning especially in the construction of particular rules and rituals; or, in other words, it has an important part in the introduction of culture to the nature of cognitive and social processes. After the introduction of concept Structure of disturbed communication and some corrections to the Levi-Strauss’s concept, I start with the proposition that the period of transition represents unstable and ‘slippery’ time in which society negotiates different meanings. That is the time when different styles of thoughts, represented by different and powerful groups that have an impact on current social, political and ideological processes, compete with each other fighting for supremacy. Their field of communication can be seen as a field of "disturbed communication", which in the final instance has a normative function: to reinforce and regulate certain attitudes, ideas and knowledge. This is achieved through the narratives which symbolise a community of newly established order in the moment of its supposed sociohistorical stabilisation. Finally, combining two different theoretical models – Levi-Strauss’s one described above with Greimas’s ideas about structures of modes of veridiction, this paper predicts chances of particular paradigmatic forms of thought in transitory Serbia to became dominant modes of thought, despite of their current low visibility in the public sphere. In mythical terms, it seems though that their domineering efforts are predetermined to success or fail, since they position themselves according to the laws immanent to these structures themselves, which on their part a priori position these structures as powerful orpowerless, influential or non

  4. Do emergency medicine residents and faculty have similar learning styles when assessed with the Kolb learning style assessment tool?

    Fredette, Jenna; O'Brien, Corinne; Poole, Christy; Nomura, Jason

    2015-04-01

    Experiential learning theory and the Kolb Learning Style Inventory (Kolb LSI) have influenced educators worldwide for decades. Knowledge of learning styles can create efficient learning environments, increase information retention, and improve learner satisfaction. Learning styles have been examined in medicine previously, but not specifically with Emergency Medicine (EM) residents and attendings. Using the Kolb LSI, the learning styles of Emergency Medicine residents and attendings were assessed. The findings showed that the majority of EM residents and attendings shared the accommodating learning style. This result was different than prior studies that found the majority of medical professionals had a converging learning style and other studies that found attendings often have different learning styles than residents. The issue of learning styles among emergency medical residents and attendings is important because learning style knowledge may have an impact on how a residency program structures curriculum and how EM residents are successfully, efficiently, and creatively educated.

  5. Structural changes in the German pharmaceutical market: price setting mechanisms based on the early benefit evaluation.

    Henschke, Cornelia; Sundmacher, Leonie; Busse, Reinhard

    2013-03-01

    In the past, free price setting mechanisms in Germany led to high prices of patented pharmaceuticals and to increasing expenditures in the pharmaceutical sector. In order to control patented pharmaceutical prices and to curb increasing pharmaceutical spending, the Act for Restructuring the Pharmaceutical Market in Statutory Health Insurance (AMNOG) came into effect on 1st January 2011. In a structured dossier, pharmaceutical manufacturers have to demonstrate the additional therapeutic benefit of the newly approved pharmaceutical compared to its appropriate comparator. According to the level of additional benefit, pharmaceuticals will be subject to price negotiations between the Federal Association of Statutory Health Insurance Funds and the pharmaceutical company concerned (or assigned to a reference price group in case of no additional benefit). Therefore, the health care reform is a first step to decision making based on "value for money". The process of price setting based on early benefit evaluation has an impact on the German as well as the European pharmaceutical markets. Therefore, these structural changes in Germany are of importance for pricing decisions in many European countries both from a political point of view and for strategic planning for pharmaceutical manufacturers, which may have an effect on insured patients' access to pharmaceuticals.

  6. Adapting Scott and Bruce's General Decision-Making Style Inventory to Patient Decision Making in Provider Choice.

    Fischer, Sophia; Soyez, Katja; Gurtner, Sebastian

    2015-05-01

    Research testing the concept of decision-making styles in specific contexts such as health care-related choices is missing. Therefore, we examine the contextuality of Scott and Bruce's (1995) General Decision-Making Style Inventory with respect to patient choice situations. Scott and Bruce's scale was adapted for use as a patient decision-making style inventory. In total, 388 German patients who underwent elective joint surgery responded to a questionnaire about their provider choice. Confirmatory factor analyses within 2 independent samples assessed factorial structure, reliability, and validity of the scale. The final 4-dimensional, 13-item patient decision-making style inventory showed satisfactory psychometric properties. Data analyses supported reliability and construct validity. Besides the intuitive, dependent, and avoidant style, a new subdimension, called "comparative" decision-making style, emerged that originated from the rational dimension of the general model. This research provides evidence for the contextuality of decision-making style to specific choice situations. Using a limited set of indicators, this report proposes the patient decision-making style inventory as valid and feasible tool to assess patients' decision propensities. © The Author(s) 2015.

    Lawden, M. D.

    This document describes the various styles which are recommended for Starlink documents. It also explains how to use the templates which are provided by Starlink to help authors create documents in a standard style. This paper is concerned mainly with conveying the ``look and feel" of the various styles of Starlink document rather than describing the technical details of how to produce them. Other Starlink papers give recommendations for the detailed aspects of document production, design, layout, and typography. The only style that is likely to be used by most Starlink authors is the Standard style.

    Highlights: • The structural analyses of the load combination are performed for the HCCR TBM-set. • Structural analyses are performed with the conventional CFD and FEM codes (ANSYS-CFX and ANSYS). • The results of stresses and deformations for all the loads conditions are confirmed to meet the design criteria. - Abstract: Using a conceptual design of the Korean Helium Cooled Ceramic Reflector (HCCR) Test Blanket Module (TBM) including the TBM-shield for testing in ITER, a structural analysis is performed according to the selected Load Combinations (LCs), which is described in the TBM Port Plug (TBM PP) System Load Specifications. Single load analyses are performed such as dead weight (DW), operating pressure (PresO), operating temperature (THO), electromagnetic (EM; MD-I, MD-II, and MD-IV), seismic (SL-1, SL-2, and SMHV), and in-TBM LOCA-IV. In addition, their results are superposed for the selected LCs. Through an analysis with 14 single load cases and 10 LC cases, it is confirmed that all load combination results meet the design criteria from the stress breakdown analysis according to the RCC-MRx.

    2016-11-01

    Human milk fat-style structured triacylglycerols were produced from microalgal oil in a continuous microfluidic reactor packed with immobilized lipase for the first time. A remarkably high conversion efficiency was demonstrated in the microreactor with reaction time being reduced by 8 times, Michaelis constant decreased 10 times, the lipase reuse times increased 2.25-fold compared to those in a batch reactor. In addition, the content of palmitic acid at sn-2 position (89.0%) and polyunsaturated fatty acids at sn-1, 3 positions (81.3%) are slightly improved compared to the product in a batch reactor. The increase of melting points (1.7°C) and decrease of crystallizing point (3°C) implied higher quality product was produced using the microfluidic technology. The main cost can be reduced from $212.3 to $14.6 per batch with the microreactor. Overall, the microfluidic bioconversion technology is promising for modified functional lipids production allowing for cost-effective approach to produce high-value microalgal coproducts.

  12. [Psychosomatic aspects of parent-child relations in atopic eczema in childhood. II. Child-rearing style, the family situation in a drawing test and structured interview].

    Ring, J; Palos, E

    1986-11-01

    To evaluate the style of education in this group of children, "scale versions" according to Stapf were used. Mothers of atopic children were found to be significantly more "strict" in their educational approach compared with control mothers (P less than 0.01). There was no significant difference between the two groups of fathers. In particular, mothers of atopic children significantly more often favored "grown-up" behavior in their children and the capacity to enjoy the joy of children was significantly less pronounced compared with controls. In the children's drawings, children with atopic eczema lacked the "friendly atmosphere" expressed in drawings of control children. Fathers of atopic children were drawn significantly smaller than the respective mothers. In animal drawings, children with atopic eczema mostly selected unpleasant or dangerous animals to describe their parents, brothers, or sisters. From the structured interviews, the following points were remarkable: atopic children more often display aggressive thoughts or behavior against their parents than do controls. Mothers of atopic children react less spontaneously and less emotionally to children's emotions. Maternal affection often takes place as a hygienic ritual or in a body and achievement-oriented fashion. Mothers of atopic children like them to behave in a "grown-up" manner.

  13. Perceived parenting styles and tobacco, alcohol and cannabis use among French adolescents: gender and family structure differentials.

    Choquet, Marie; Hassler, Christine; Morin, Delphine; Falissard, Bruno; Chau, Nearkasen

    2008-01-01

    To assess associations between parental control or parental emotional support and current tobacco, alcohol or cannabis use among 12-18-year-old students, according to gender and family structure (intact family, reconstituted family, single-parent family). A cross-sectional survey was conducted in a national representative sample in France (2003) of 6-12th grade students (N = 16,532), as a part of the ESPAD study (European Study Project on Alcohol and Other Drugs). The self-administered questionnaire included questions on last 30 days' consumption of alcohol, tobacco and cannabis as well as on socio-demographic characteristics, school characteristics, and some simple questions on parental control and parental emotional support. Logistic modelling was carried out and (adjusted Odds Ratio) Ora calculated, adjusted for age, parental educational and characteristics of the school. A negative relationship exists between parental control and substance use, but this relationship is more marked for tobacco (OR a between 1.8 and 5.6 according to level of control, family status and gender) and cannabis (OR between 1.5 and 6.4) than for alcohol (OR a between 1.0 and 2.7). Parental control is more markedly related to substance use in girls than in boys. These tendencies were observed for intact families as well as for single-parent families or reconstituted families. Parental control has a greater impact than emotional support. Among girls, emotional support has a greater impact than among boys. There is a gradient relationship between parental control and current consumption, especially among girls. Thus, there may be a need for parental control, whatever the family structure.

  14. Conflict resolution styles in the nursing profession.

    Losa Iglesias, Marta Elena; Becerro de Bengoa Vallejo, Ricardo

    2012-12-01

    Managers, including those in nursing environments, may spend much of their time addressing employee conflicts. If not handled properly, conflict may significantly affect employee morale, increase turnover, and even result in litigation, ultimately affecting the overall well-being of the organization. A clearer understanding of the factors that underlie conflict resolution styles could lead to the promotion of better management strategies. The aim of this research was to identify the predominant conflict resolution styles used by a sample of Spanish nurses in two work settings, academic and clinical, in order to determine differences between these environments. The effects of employment level and demographic variables were explored as well. Descriptive cross-sectional survey study. Our sample consisted of professional nurses in Madrid, Spain, who worked in either a university setting or a clinical care setting. Within each of these environments, nurses worked at one of three levels: full professor, assistant professor, or scholarship professor in the academic setting; and nursing supervisor, registered staff nurse, or nursing assistant in the clinical setting. Conflict resolution style was examined using the standardized Thomas-Kilmann Conflict Mode Instrument, a dual-choice questionnaire that assesses a respondent's predominant style of conflict resolution. Five styles are defined: accommodating, avoiding, collaborating, competing, and compromising. Participants were asked to give answers that characterized their dominant response in a conflict situation involving either a superior or a subordinate. Descriptive and inferential statistics were used to examine the relationship between workplace setting and conflict resolution style. The most common style used by nurses overall to resolve workplace conflict was compromising, followed by competing, avoiding, accommodating, and collaborating. There was a significant overall difference in styles between nurses who worked

    Nicholas Spellmon

    2015-01-01

    Full Text Available SET (Suppressor of variegation, Enhancer of Zeste, Trithorax and MYND (Myeloid-Nervy-DEAF1 domain-containing proteins (SMYD have been found to methylate a variety of histone and non-histone targets which contribute to their various roles in cell regulation including chromatin remodeling, transcription, signal transduction, and cell cycle control. During early development, SMYD proteins are believed to act as an epigenetic regulator for myogenesis and cardiomyocyte differentiation as they are abundantly expressed in cardiac and skeletal muscle. SMYD proteins are also of therapeutic interest due to the growing list of carcinomas and cardiovascular diseases linked to SMYD overexpression or dysfunction making them a putative target for drug intervention. This review will examine the biological relevance and gather all of the current structural data of SMYD proteins.

  16. Transport equations, Level Set and Eulerian mechanics. Application to fluid-structure coupling

    Maitre, E.

    2008-11-01

    My works were devoted to numerical analysis of non-linear elliptic-parabolic equations, to neutron transport equation and to the simulation of fabrics draping. More recently I developed an Eulerian method based on a level set formulation of the immersed boundary method to deal with fluid-structure coupling problems arising in bio-mechanics. Some of the more efficient algorithms to solve the neutron transport equation make use of the splitting of the transport operator taking into account its characteristics. In the present work we introduced a new algorithm based on this splitting and an adaptation of minimal residual methods to infinite dimensional case. We present the case where the velocity space is of dimension 1 (slab geometry) and 2 (plane geometry) because the splitting is simpler in the former

  18. Online measurement for geometrical parameters of wheel set based on structure light and CUDA parallel processing

    Wu, Kaihua; Shao, Zhencheng; Chen, Nian; Wang, Wenjie

    2018-01-01

    The wearing degree of the wheel set tread is one of the main factors that influence the safety and stability of running train. Geometrical parameters mainly include flange thickness and flange height. Line structure laser light was projected on the wheel tread surface. The geometrical parameters can be deduced from the profile image. An online image acquisition system was designed based on asynchronous reset of CCD and CUDA parallel processing unit. The image acquisition was fulfilled by hardware interrupt mode. A high efficiency parallel segmentation algorithm based on CUDA was proposed. The algorithm firstly divides the image into smaller squares, and extracts the squares of the target by fusion of k_means and STING clustering image segmentation algorithm. Segmentation time is less than 0.97ms. A considerable acceleration ratio compared with the CPU serial calculation was obtained, which greatly improved the real-time image processing capacity. When wheel set was running in a limited speed, the system placed alone railway line can measure the geometrical parameters automatically. The maximum measuring speed is 120km/h.

  19. Smart Winery: A Real-Time Monitoring System for Structural Health and Ullage in Fino Style Wine Casks.

    Cañete, Eduardo; Chen, Jaime; Martín, Cristian; Rubio, Bartolomé

    2018-03-07

    The rapid development in low-cost sensor and wireless communication technology has made it possible for a large number of devices to coexist and exchange information autonomously. It has been predicted that a substantial number of devices will be able to exchange and provide information about an environment with the goal of improving our lives, under the well-known paradigm of the Internet of Things (IoT). One of the main applications of these kinds of devices is the monitoring of scenarios. In order to improve the current wine elaboration process, this paper presents a real-time monitoring system to supervise the status of wine casks. We have focused on a special kind of white wine, called Fino, principally produced in Andalusia (Southern Spain). The process by which this kind of wind is monitored is completely different from that of red wine, as the casks are not completely full and, due to the fact that they are not renewed very often, are more prone to breakage. A smart cork prototype monitors the structural health, the ullage, and the level of light inside the cask and the room temperature. The advantage of this smart cork is that it allows winemakers to monitor, in real time, the status of each wine cask so that, if an issue is detected (e.g., a crack appears in the cask), they can act immediately to resolve it. Moreover, abnormal parameters or incorrect environmental conditions can be detected in time before the wine loses its desired qualities. The system has been tested in "Bodegas San Acacio," a winery based in Montemayor, a town in the north of Andalusia. Results show that the use of such a system can provide a solution that tracks the evolution and assesses the suitability of the delicate wine elaboration process in real time, which is especially important for the kind of wine considered in this paper.

  1. Comparative population structure of Plasmodium malariae and Plasmodium falciparum under different transmission settings in Malawi

    Molyneux Malcolm E

    2011-02-01

    Full Text Available Abstract Background Described here is the first population genetic study of Plasmodium malariae, the causative agent of quartan malaria. Although not as deadly as Plasmodium falciparum, P. malariae is more common than previously thought, and is frequently in sympatry and co-infection with P. falciparum, making its study increasingly important. This study compares the population parameters of the two species in two districts of Malawi with different malaria transmission patterns - one seasonal, one perennial - to explore the effects of transmission on population structures. Methods Six species-specific microsatellite markers were used to analyse 257 P. malariae samples and 257 P. falciparum samples matched for age, gender and village of residence. Allele sizes were scored to within 2 bp for each locus and haplotypes were constructed from dominant alleles in multiple infections. Analysis of multiplicity of infection (MOI, population differentiation, clustering of haplotypes and linkage disequilibrium was performed for both species. Regression analyses were used to determine association of MOI measurements with clinical malaria parameters. Results Multiple-genotype infections within each species were common in both districts, accounting for 86.0% of P. falciparum and 73.2% of P. malariae infections and did not differ significantly with transmission setting. Mean MOI of P. falciparum was increased under perennial transmission compared with seasonal (3.14 vs 2.59, p = 0.008 and was greater in children compared with adults. In contrast, P. malariae mean MOI was similar between transmission settings (2.12 vs 2.11 and there was no difference between children and adults. Population differentiation showed no significant differences between villages or districts for either species. There was no evidence of geographical clustering of haplotypes. Linkage disequilibrium amongst loci was found only for P. falciparum samples from the seasonal transmission

    More than 7 billion visits are made by patients to ambulatory services every year in mainland China. Healthcare-associated infections are becoming a new source of illness for outpatients. Little is known about infection prevention, control structure, resources available, and basic practices in outpatient settings. In 2014, we conducted a multisite survey. Five provinces were invited to participate based on geographic dispersion. Self-assessment questionnaires regarding the structure, infrastructure, apparatus and materials, and basic activities of infection prevention and control were issued to 25 hospitals and 5 community health centers in each province. A weight was assigned to each question according to its importance. Overall, 146 of 150 facilities (97.3%) participated in this study. The average survey score was 77.6 (95% confidence interval 75.7-79.5) and varied significantly between the different gross domestic product areas (P infection prevention and control was practiced consistently, although there were lapses in some areas.

  3. BACHSCORE. A tool for evaluating efficiently and reliably the quality of large sets of protein structures

    Sarti, E.; Zamuner, S.; Cossio, P.; Laio, A.; Seno, F.; Trovato, A.

    2013-12-01

    In protein structure prediction it is of crucial importance, especially at the refinement stage, to score efficiently large sets of models by selecting the ones that are closest to the native state. We here present a new computational tool, BACHSCORE, that allows its users to rank different structural models of the same protein according to their quality, evaluated by using the BACH++ (Bayesian Analysis Conformation Hunt) scoring function. The original BACH statistical potential was already shown to discriminate with very good reliability the protein native state in large sets of misfolded models of the same protein. BACH++ features a novel upgrade in the solvation potential of the scoring function, now computed by adapting the LCPO (Linear Combination of Pairwise Orbitals) algorithm. This change further enhances the already good performance of the scoring function. BACHSCORE can be accessed directly through the web server: bachserver.pd.infn.it.

  4. Characterizing English Poetic Style Using Complex Networks

    Roxas-Villanueva, Ranzivelle Marianne; Nambatac, Maelori Krista; Tapang, Giovanni

    Complex networks have been proven useful in characterizing written texts. Here, we use networks to probe if there exist a similarity within, and difference across, era as reflected within the poem's structure. In literary history, boundary lines are set to distinguish the change in writing styles through time. We obtain the network parameters and motif frequencies of 845 poems published from 1522 to 1931 and relate this to the writing of the Elizabethan, 17th Century, Augustan, Romantic and Victorian eras. Analysis of the different network parameters shows a significant difference of the Augustan era (1667-1780) with the rest. The network parameters and the convex hull and centroids of the motif frequencies reflect the adjectival sequence pattern of the poems of the Augustan era.

  5. How to design a cartographic continuum to help users to navigate between two topographic styles?

    Ory, Jérémie; Touya, Guillaume; Hoarau, Charlotte; Christophe, Sidonie

    2018-05-01

    Geoportals and geovisualization tools provide to users various cartographic abstractions that describe differently a geographical space. Our purpose is to be able to design cartographic continuums, i.e. a set of in-between maps allowing users to navigate between two topographic styles. This paper addresses the problem of the interpolation between two topographic abstractions with different styles. We detail our approach in two steps. Firstly, we setup a comparison in order to identify which structural elements of a cartographic abstraction should be interpolated. Secondly, we propose an approach based on two design methods for maps interpolation.

  6. Leadership styles and theories.

    Giltinane, Charlotte Louise

    It is useful for healthcare professionals to be able to identify the leadership styles and theories relevant to their nursing practice. Being adept in recognising these styles enables nurses to develop their skills to become better leaders, as well as improving relationships with colleagues and other leaders, who have previously been challenging to work with. This article explores different leadership styles and theories, and explains how they relate to nursing practice.

    The purpose of this study was to determine whether a mineral-rich extract derived from the red marine algae Lithothamnion calcareum could be used as a dietary supplement for prevention of bone mineral loss. Sixty C57BL/6 mice were divided into three groups based on diet: the first group received a high-fat Western-style diet (HFWD), the second group was fed the same HFWD along with the mineral-rich extract included as a dietary supplement, and the third group was used as a control and was fed a low-fat rodent chow diet (AIN76A). Mice were maintained on the respective diets for 15 months. Then, long bones (femora and tibiae) from both males and females were analyzed by three-dimensional micro-computed tomography (micro-CT) and (bones from female mice) concomitantly assessed in bone strength studies. Tartrate-resistant acid phosphatase (TRAP), osteocalcin, and N-terminal peptide of type I procollagen (PINP) were assessed in plasma samples obtained from female mice at the time of sacrifice. To summarize, female mice on the HFWD had reduced bone mineralization and reduced bone strength relative to female mice on the low-fat chow diet. The bone defects in female mice on the HFWD were overcome in the presence of the mineral-rich supplement. In fact, female mice receiving the mineral-rich supplement in the HFWD had better bone structure/function than did female mice on the low-fat chow diet. Female mice on the mineral-supplemented HFWD had higher plasma levels of TRAP than mice of the other groups. There were no differences in the other two markers. Male mice showed little diet-specific differences by micro-CT.

    Parenting style is strongly associated with adolescent health. However, little is known about how school disciplinary style relates to health. We categorized adolescents' perceptions of their schools as authoritative, authoritarian, permissive, or neglectful, and test whether perceived school disciplinary style is associated with health. We analyze data from the RISE Up study (Reducing Health Inequities Through Social and Educational Change Follow-up), comprised of baseline (eighth grade) and 2-year follow-up surveys (10th grade) from 1,159 low-income minority adolescents in Los Angeles attending 157 schools. At 10th grade, students' ratings of school support and structure were used to categorize perceived school disciplinary style as authoritative (highest tertile for support and structure), authoritarian (low support, high structure), permissive (high support, low structure), neglectful (low on both dimensions), and average (middle tertile on either dimension). Mixed effects logistic regressions controlling for sociodemographic factors, parenting style, grades, and baseline health tested whether school disciplinary style was associated with substance use, violence, bullying, and depression symptoms. Risky behaviors varied by school disciplinary style. After adjusting for covariates, compared with an average school disciplinary style, a neglectful school was associated with higher odds of substance use (adjusted odds ratio [AOR] 2.3, p authoritative school was associated with lower odds of substance use (AOR .6, p = .049), violence (AOR .6, p = .03), and bullying (AOR .5, p = .001).

    2015-01-01

    This paper reviews the insights that research offers on the impact of different leadership styles on innovation management. To do so, we develop a framework structuring existing insights into four generic dimensions: people, means, effects, and goals. Based on this framework, we review studies on...... demands on leadership. Against this background, transformational leadership is not the only style to lead innovations, but different leadership styles fit differently well with different innovation types and stages. However, the specification of this fit is still very incomplete and the answer...

  11. The regional geological and structural setting of the uraniferous granitic provinces of Southern Africa

    Jacob, R.E.; Corner, B.; Brynard, H.J.

    1986-01-01

    Uranium-bearing granites, comprising both potentially economic deposits and source rocks for uranium deposits is duricrustal and sedimentary sequences, are confined chiefly to the mobile belts of Southern Africa and to the Cape granites emplaced during late Precambrian times. The direct uranium potential of the mobile belts, i.e. the Damara, Namaqua-Natal and Limpopo belts, decreases with an increase in the age of associated ensialic diastrophism. This review paper is thus mainly confined to the Damara Belt, although a brief discussion of the potential of the Namaqua Belt is presented. Aspects of the Damara Belt that are discussed in detail, with particular reference to the occurrence of uraniferous granite, include regional tectonic setting, stratigraphy, structure, metamorphism and the patterns and origin of the uranium mineralization. Initial concentrations of uranium in basement and Nosib rocks have led, through ultrametamorphism and fractionation, to uraniferous granites of both economic and sub-economic grade. These granites, in turn, have acted as source of secondary mineralization in overlying superficial calcareous and gypsiferous deposits. The Damara Belt thus provides a good example of multicyclic processes of ore formation. With regard to the uraniferous granites of Namaqualand it is concluded that the porphyroblastic gneisses and late-intrusive Concordia granites, although not of direct economic interest, represent major sources of uranium for secondary superficial deposits. Smaller bodies of late-phase differentiates associated with the Concordia granitic gneiss may themselves, however, represent potentially economically viable deposits

  12. Structured Mentoring for Workforce Engagement and Professional Development in Public Health Settings.

    Dopson, Stephanie A; Griffey, Sue; Ghiya, Neelam; Laird, Susan; Cyphert, Aubrey; Iskander, John

    2017-05-01

    Mentoring is commonly used to facilitate professional growth and workforce development in a variety of settings. Organizations can use mentoring to help achieve broader personnel goals including leadership development and succession planning. While mentorship can be incorporated into training programs in public health, there are other examples of structured mentoring, with time commitments ranging from minutes to months or longer. Based on a review of the literature in public health and aggregated personal subject matter expertise of existing programs at the Centers for Disease Control and Prevention, we summarize selected mentoring models that vary primarily by time commitments and meeting frequency and identify specific work situations to which they may be applicable, primarily from the federal job experience point of view. We also suggest specific tasks that mentor-mentee pairs can undertake, including review of writing samples, practice interviews, and development of the mentee's social media presence. The mentor-mentee relationship should be viewed as a reciprocally beneficial one that can be a source of learning and personal growth for individuals at all levels of professional achievement and across the span of their careers.

  13. Structural relations in the effect of convenience food satisfaction and quality of life according to dietary style: Comparative study of singles in metropolitan area of Korea, Japan and China.

    Kim, Boram; Joo, Nami

    2014-06-01

    Due to recent changes in social structure, single-person households are on the rise worldwide and therefore the interest in the quality of life of singles is increasing, but the research on the relationships related to their diet-related quality of life is scarce. This research analyzes the structural relations in the effect of convenience food satisfaction and quality of life according to dietary style of Korean, Japanese and Chinese singles. The targets of this study were Korean, Japanese, and Chinese singles, identified as adults between the ages of 25 and 54, having economic capabilities or working and living alone, either legally or in actuality having no partner. A statistical analysis was conducted using SPSS12.0 for Windows and SEM using AMOS 5.0 statistics package. The reliability of these findings was supported by a Cronbach's alpha coefficient of 0.6 and higher for all the factors. In an attempt to study the level of satisfaction with convenience food in accordance to dietary style and the quality of life of singles, a structural equation model was constructed and analyzed. Of the three countries, regarding the effect of dietary style on singles' quality of life, the convenience-oriented style was found to have a negative effect on Korean singles' overall quality of life, but a positive effect on Japanese singles' overall quality of life, and a negative effect on Chinese singles' positive psychological aspect of quality of life. In addition, although Chinese singles have a high level of interest in health, they have an overall high level of satisfaction regarding fast food and its nutritional value. The number of singles in Korea, Japan, and China has been consistently increasing in recent years, and there is a need for continuous interest in their healthy dietary lifestyles in terms of convenience, economy, and taste.

  16. The Expanded FindCore Method for Identification of a Core Atom Set for Assessment of Protein Structure Prediction

    Snyder, David A.; Grullon, Jennifer; Huang, Yuanpeng J.; Tejero, Roberto; Montelione, Gaetano T.

    2014-01-01

    Maximizing the scientific impact of NMR-based structure determination requires robust and statistically sound methods for assessing the precision of NMR-derived structures. In particular, a method to define a core atom set for calculating superimpositions and validating structure predictions is critical to the use of NMR-derived structures as targets in the CASP competition. FindCore (D.A. Snyder and G.T. Montelione PROTEINS 2005;59:673–686) is a superimposition independent method for identifying a core atom set, and partitioning that set into domains. However, as FindCore optimizes superimposition by sensitively excluding not-well-defined atoms, the FindCore core may not comprise all atoms suitable for use in certain applications of NMR structures, including the CASP assessment process. Adapting the FindCore approach to assess predicted models against experimental NMR structures in CASP10 required modification of the FindCore method. This paper describes conventions and a standard protocol to calculate an “Expanded FindCore” atom set suitable for validation and application in biological and biophysical contexts. A key application of the Expanded FindCore method is to identify a core set of atoms in the experimental NMR structure for which it makes sense to validate predicted protein structure models. We demonstrate the application of this Expanded FindCore method in characterizing well-defined regions of 18 NMR-derived CASP10 target structures. The Expanded FindCore protocol defines “expanded core atom sets” that match an expert’s intuition of which parts of the structure are sufficiently well-defined to use in assessing CASP model predictions. We also illustrate the impact of this analysis on the CASP GDT assessment scores. PMID:24327305

    2009-01-01

    Interpersonal style is an aspect of personality related to the particular way individuals participate and gain influence in social contexts. It has its origin in childhood’s first social interactions within the family group. It is suggested that the individual position in the family structure, namely birth order, is an important variable in this process. The present study investigated combined effects of sex and birth order on interpersonal style. A sample of 435 college students (196 men and...

  2. AUTOMATIC ARCHITECTURAL STYLE RECOGNITION

    M. Mathias

    2012-09-01

    Full Text Available Procedural modeling has proven to be a very valuable tool in the field of architecture. In the last few years, research has soared to automatically create procedural models from images. However, current algorithms for this process of inverse procedural modeling rely on the assumption that the building style is known. So far, the determination of the building style has remained a manual task. In this paper, we propose an algorithm which automates this process through classification of architectural styles from facade images. Our classifier first identifies the images containing buildings, then separates individual facades within an image and determines the building style. This information could then be used to initialize the building reconstruction process. We have trained our classifier to distinguish between several distinct architectural styles, namely Flemish Renaissance, Haussmannian and Neoclassical. Finally, we demonstrate our approach on various street-side images.

    2017-09-19

    With current emphasis on leadership in medicine, this study explores Goleman's leadership styles of medical education leaders at different hierarchical levels and gain insight into factors that contribute to the appropriateness of practices. Forty two leaders (28 first-level with limited formal authority, eight middle-level with wider program responsibility and six senior- level with higher organizational authority) rank ordered their preferred Goleman's styles and provided comments. Eight additional senior leaders were interviewed in-depth. Differences in ranked styles within groups were determined by Friedman tests and Wilcoxon tests. Based upon style descriptions, confirmatory template analysis was used to identify Goleman's styles for each interviewed participant. Content analysis was used to identify themes that affected leadership styles. There were differences in the repertoire and preferred styles at different leadership levels. As a group, first-level leaders preferred democratic, middle-level used coaching while the senior leaders did not have one preferred style and used multiple styles. Women and men preferred democratic and coaching styles respectively. The varied use of styles reflected leadership conceptualizations, leader accountabilities, contextual adaptations, the situation and its evolution, leaders' awareness of how they themselves were situated, and personal preferences and discomfort with styles. The not uncommon use of pace-setting and commanding styles by senior leaders, who were interviewed, was linked to working with physicians and delivering quickly on outcomes. Leaders at different levels in medical education draw from a repertoire of styles. Leadership development should incorporate learning of different leadership styles, especially at first- and mid-level positions.

  8. Impact of Implementing a Wiki to Develop Structured Electronic Order Sets on Physicians' Intention to Use Wiki-Based Order Sets.

    Archambault, Patrick Michel; Beaupré, Pierre; Bégin, Laura; Dupuis, Audrey; Côté, Mario; Légaré, France

    2016-05-17

    Wikis have the potential to promote best practices in health systems by sharing order sets with a broad community of stakeholders. However, little is known about the impact of using a wiki on clinicians' intention to use wiki-based order sets. The aims of this study were: (1) to describe the use of a wiki to create structured order sets for a single emergency department; (2) to evaluate whether the use of this wiki changed emergency physicians' future intention to use wiki-based order sets; and (3) to understand the impact of using the wiki on the behavioral determinants for using wiki-based order sets. This was a pre/post-intervention mixed-methods study conducted in one hospital in Lévis, Quebec. The intervention was comprised of receiving access to and being motivated by the department head to use a wiki for 6 months to create electronic order sets designed to be used in a computer physician order entry system. Before and after our intervention, we asked participants to complete a previously validated questionnaire based on the Theory of Planned Behavior. Our primary outcome was the intention to use wiki-based order sets in clinical practice. We also assessed participants' attitude, perceived behavioral control, and subjective norm to use wiki-based order sets. Paired pre- and post-Likert scores were compared using Wilcoxon signed-rank tests. The post-questionnaire also included open-ended questions concerning participants' comments about the wiki, which were then classified into themes using an existing taxonomy. Twenty-eight emergency physicians were enrolled in the study (response rate: 100%). Physicians' mean intention to use a wiki-based reminder was 5.42 (SD 1.04) before the intervention, and increased to 5.81 (SD 1.25) on a 7-point Likert scale (P =.03) after the intervention. Participants' attitude towards using a wiki-based order set also increased from 5.07 (SD 0.90) to 5.57 (SD 0.88) (P =.003). Perceived behavioral control and subjective norm did not

  10. The structural style of foot wall shortcuts along the eastern foothills of the Colombian eastern cordillera. Differences with other inversion related structures

    Mora, Andres; Parra, Mauricio

    2008-01-01

    For the first time we show geological evidence of unambiguously documented foot wall shortcuts adjacent to the trace of inverted master normal faults, in the Eastern Cordillera of Colombia. The Eastern Cordillera is an orogen whose width and location are traced by a Mesozoic Graben. However, few structures related with the Graben have been documented up to the date. In this study we propose the Ariari-Guatiquia region as a type location for a unique observation of foot wall shortcuts. The master normal faults in the Ariari-Guatiquia region, and documented in this manuscript, were active during the Lower Cretaceous, partially inverted during the Andean orogenesis (since the Oligocene at least) and active still nowadays. In the hanging wall basins of those master normal faults, like the Servita fault, all the Cretaceous syn-rift sequence has been deposited and maximum paleo-temperatures in the lowermost Cretaceous rocks are higher than those for the Zircon FT partial annealing zone (250 Celsius degrade; 23,15 K). In contraction, the inverted master normal faults are high angle basement involved features that generated the main topographic contrast and exposing Lower Cretaceous units or older. In contrast, in the adjacent foot wall shortcuts only part of the syn-rift Lower Cretaceous sequence was deposited or more commonly was not deposited at all. Maximum paleo-temperatures reached by the basal Cretaceous units exposed in the hanging wall blocks of the foot wall shortcuts are always less than those of the Zircon FT partial annealing zone (250 Celsius degrade; 23,15 K). Finally we use AFT data to document that the foot wall shortcuts originated during the Late Miocene and later as shallowly dipping faults generating low elevation hanging wall areas. All the described features are present in the Ariari-Guatiquia region. However, northwards and along strike in the Eastern foothills there is a lot of partially analogue scenarios with respect to those described in the

For every nucleus, the Nuclear Structure Data File contains evaluated nuclear structure information. This manual describes a standard input format for nuclear structure data. The format is sufficiently structured that bulk data can be entered efficiently. At the same time, the structure is open-ended and can accommodate most measured or deduced quantities that yield nuclear structure information. Computer programs have been developed at the Data Project to perform consistency checking and routine calculations. Programs are also used for preparing level scheme drawings. (U.S.)

  13. Three sets of crystallographic sub-planar structures in quartz formed by tectonic deformation

    Derez, Tine; Pennock, Gill; Drury, Martyn; Sintubin, Manuel

    2016-05-01

    In quartz, multiple sets of fine planar deformation microstructures that have specific crystallographic orientations parallel to planes with low Miller-Bravais indices are commonly considered as shock-induced planar deformation features (PDFs) diagnostic of shock metamorphism. Using polarized light microscopy, we demonstrate that up to three sets of tectonically induced sub-planar fine extinction bands (FEBs), sub-parallel to the basal, γ, ω, and π crystallographic planes, are common in vein quartz in low-grade tectonometamorphic settings. We conclude that the observation of multiple (2-3) sets of fine scale, closely spaced, crystallographically controlled, sub-planar microstructures is not sufficient to unambiguously distinguish PDFs from tectonic FEBs.

    The formation of large scale structures is considered within a model with string on toroidal space-time. Firstly, the space-time geometry is presented. In this geometry, the Universe is represented by a string describing a torus surface. Thereafter, the large scale structure of the Universe is derived from the string oscillations. The results are in agreement with the cellular structure of the large scale distribution and with the theory of a Cantorian space-time.

  20. Identification of individual coherent sets associated with flow trajectories using coherent structure coloring

    Schlueter-Kuck, Kristy L.; Dabiri, John O.

    2017-09-01

    We present a method for identifying the coherent structures associated with individual Lagrangian flow trajectories even where only sparse particle trajectory data are available. The method, based on techniques in spectral graph theory, uses the Coherent Structure Coloring vector and associated eigenvectors to analyze the distance in higher-dimensional eigenspace between a selected reference trajectory and other tracer trajectories in the flow. By analyzing this distance metric in a hierarchical clustering, the coherent structure of which the reference particle is a member can be identified. This algorithm is proven successful in identifying coherent structures of varying complexities in canonical unsteady flows. Additionally, the method is able to assess the relative coherence of the associated structure in comparison to the surrounding flow. Although the method is demonstrated here in the context of fluid flow kinematics, the generality of the approach allows for its potential application to other unsupervised clustering problems in dynamical systems such as neuronal activity, gene expression, or social networks.

  1. Finding Chemical Structures Corresponding to a Set of Coordinates in Chemical Descriptor Space.

    Miyao, Tomoyuki; Funatsu, Kimito

    2017-08-01

    When chemical structures are searched based on descriptor values, or descriptors are interpreted based on values, it is important that corresponding chemical structures actually exist. In order to consider the existence of chemical structures located in a specific region in the chemical space, we propose to search them inside training data domains (TDDs), which are dense areas of a training dataset in the chemical space. We investigated TDDs' features using diverse and local datasets, assuming that GDB11 is the chemical universe. These two analyses showed that considering TDDs gives higher chance of finding chemical structures than a random search-based method, and that novel chemical structures actually exist inside TDDs. In addition to those findings, we tested the hypothesis that chemical structures were distributed on the limited areas of chemical space. This hypothesis was confirmed by the fact that distances among chemical structures in several descriptor spaces were much shorter than those among randomly generated coordinates in the training data range. © 2017 Wiley-VCH Verlag GmbH & Co.

  3. Evaluation of Different Methods for Identification of Structural Alerts Using Chemical Ames Mutagenicity Data Set as a Benchmark.

    2017-06-19

    Identification of structural alerts for toxicity is useful in drug discovery and other fields such as environmental protection. With structural alerts, researchers can quickly identify potential toxic compounds and learn how to modify them. Hence, it is important to determine structural alerts from a large number of compounds quickly and accurately. There are already many methods reported for identification of structural alerts. However, how to evaluate those methods is a problem. In this paper, we tried to evaluate four of the methods for monosubstructure identification with three indices including accuracy rate, coverage rate, and information gain to compare their advantages and disadvantages. The Kazius' Ames mutagenicity data set was used as the benchmark, and the four methods were MoSS (graph-based), SARpy (fragment-based), and two fingerprint-based methods including Bioalerts and the fingerprint (FP) method we previously used. The results showed that Bioalerts and FP could detect key substructures with high accuracy and coverage rates because they allowed unclosed rings and wildcard atom or bond types. However, they also resulted in redundancy so that their predictive performance was not as good as that of SARpy. SARpy was competitive in predictive performance in both training set and external validation set. These results might be helpful for users to select appropriate methods and further development of methods for identification of structural alerts.

  4. Extreme Programming: Maestro Style

    Norris, Jeffrey; Fox, Jason; Rabe, Kenneth; Shu, I-Hsiang; Powell, Mark

    2009-01-01

    "Extreme Programming: Maestro Style" is the name of a computer programming methodology that has evolved as a custom version of a methodology, called extreme programming that has been practiced in the software industry since the late 1990s. The name of this version reflects its origin in the work of the Maestro team at NASA's Jet Propulsion Laboratory that develops software for Mars exploration missions. Extreme programming is oriented toward agile development of software resting on values of simplicity, communication, testing, and aggressiveness. Extreme programming involves use of methods of rapidly building and disseminating institutional knowledge among members of a computer-programming team to give all the members a shared view that matches the view of the customers for whom the software system is to be developed. Extreme programming includes frequent planning by programmers in collaboration with customers, continually examining and rewriting code in striving for the simplest workable software designs, a system metaphor (basically, an abstraction of the system that provides easy-to-remember software-naming conventions and insight into the architecture of the system), programmers working in pairs, adherence to a set of coding standards, collaboration of customers and programmers, frequent verbal communication, frequent releases of software in small increments of development, repeated testing of the developmental software by both programmers and customers, and continuous interaction between the team and the customers. The environment in which the Maestro team works requires the team to quickly adapt to changing needs of its customers. In addition, the team cannot afford to accept unnecessary development risk. Extreme programming enables the Maestro team to remain agile and provide high-quality software and service to its customers. However, several factors in the Maestro environment have made it necessary to modify some of the conventional extreme

  8. Neural codes of seeing architectural styles.

    Choo, Heeyoung; Nasar, Jack L; Nikrahei, Bardia; Walther, Dirk B

    2017-01-10

    Images of iconic buildings, such as the CN Tower, instantly transport us to specific places, such as Toronto. Despite the substantial impact of architectural design on people's visual experience of built environments, we know little about its neural representation in the human brain. In the present study, we have found patterns of neural activity associated with specific architectural styles in several high-level visual brain regions, but not in primary visual cortex (V1). This finding suggests that the neural correlates of the visual perception of architectural styles stem from style-specific complex visual structure beyond the simple features computed in V1. Surprisingly, the network of brain regions representing architectural styles included the fusiform face area (FFA) in addition to several scene-selective regions. Hierarchical clustering of error patterns further revealed that the FFA participated to a much larger extent in the neural encoding of architectural styles than entry-level scene categories. We conclude that the FFA is involved in fine-grained neural encoding of scenes at a subordinate-level, in our case, architectural styles of buildings. This study for the first time shows how the human visual system encodes visual aspects of architecture, one of the predominant and longest-lasting artefacts of human culture.

  9. Style in knitted textiles and fashion

    Štemberger, M.; Pavko-Čuden, A.

    2017-10-01

    The presented research relates the basic elements of the art theory with the concept of style and fashion design. The objective of the research was to determine how style is manifested in knitting in different periods of fashion seasons. The collections of three designers were compared: Missoni, Issey Miyake and Sonia Rykiel, in four different seasons in three different years. The basic artistic elements used in the presented research were: point, line, light-dark and colour together with syntactic rules. A combination of different elements and syntactic rules refers to different artistic languages, which have their own artistic grammar, i.e. a different style. All three investigated fashion designers used knitting in their collections as a significant element which defined their style. Different knitting technologies as well as different yarns made of synthetic or natural fibres in all colour spectra significantly influence the surface of a knitted fabric. Even when the technology is the same, the use of different materials, structures, colours, etc. creates various unique surfaces. The method used in the presented research was a style matrix which is developed from the axiomatic system. Only the part dealing with the language of fine arts and the pictorial speech - the style of a certain designer and a certain work of art/knitted fabric was used. After the selected three designers were examined through all the periods, it was concluded that each designer can be characterised by his own style. Despite the influencing fashion trends, all the compared designers still retained their own style, their own techniques, their own inspirations.

    In high-performance liquid chromatography, quantitative structure-retention relationships (QSRRs) are applied to model the relation between chromatographic retention and quantities derived from molecular structure of analytes. Classically a substantial number of test analytes is used to build QSRR models. This makes their application laborious and time consuming. In this work a strategy is presented to build QSRR models based on selected reduced calibration sets. The analytes in the reduced calibration sets are selected from larger sets of analytes by applying the algorithm of Kennard and Stone on the molecular descriptors used in the QSRR concerned. The strategy was applied on three QSRR models of different complexity, relating logk{sub w} or log k with either: (i) log P, the n-octanol-water partition coefficient, (ii) calculated quantum chemical indices (QCI), or (iii) descriptors from the linear solvation energy relationship (LSER). Models were developed and validated for 76 reversed-phase high-performance liquid chromatography systems. From the results we can conclude that it is possible to develop log P models suitable for the future prediction of retentions with as few as seven analytes. For the QCI and LSER models we derived the rule that three selected analytes per descriptor are sufficient. Both the dependent variable space, formed by the retention values, and the independent variable space, formed by the descriptors, are covered well by the reduced calibration sets. Finally guidelines to construct small calibration sets are formulated.

  12. DESIGN OF STRUCTURAL ELEMENTS IN THE EVENT OF THE PRE-SET RELIABILITY, REGULAR LOAD AND BEARING CAPACITY DISTRIBUTION

    Tamrazyan Ashot Georgievich

    2012-10-01

    Full Text Available Accurate and adequate description of external influences and of the bearing capacity of the structural material requires the employment of the probability theory methods. In this regard, the characteristic that describes the probability of failure-free operation is required. The characteristic of reliability means that the maximum stress caused by the action of the load will not exceed the bearing capacity. In this paper, the author presents a solution to the problem of calculation of structures, namely, the identification of reliability of pre-set design parameters, in particular, cross-sectional dimensions. If the load distribution pattern is available, employment of the regularities of distributed functions make it possible to find the pattern of distribution of maximum stresses over the structure. Similarly, we can proceed to the design of structures of pre-set rigidity, reliability and stability in the case of regular load distribution. We consider the element of design (a monolithic concrete slab, maximum stress S which depends linearly on load q. Within a pre-set period of time, the probability will not exceed the values according to the Poisson law. The analysis demonstrates that the variability of the bearing capacity produces a stronger effect on relative sizes of cross sections of a slab than the variability of loads. It is therefore particularly important to reduce the coefficient of variation of the load capacity. One of the methods contemplates the truncation of the bearing capacity distribution by pre-culling the construction material.

  13. The effects of structural setting on the azimuthal velocities of blast induced ground motion in perlite

    Beattie, Susan G. [New Mexico Inst. of Mining and Technology, Socorro, NM (United States)

    1995-02-01

    A series of small scale explosive tests were performed during the spring of 1994 at a perlite mine located near Socorro, NM. The tests were designed to investigate the azimuthal or directional relationship between small scale geologic structures such as joints and the propagation of explosively induced ground motion. Three shots were initiated within a single borehole located at ground zero (gz) at depths varying from the deepest at 83 m (272 ft) to the shallowest at 10 m (32 ft). The intermediate shot was initiated at a depth of 63 m (208 ft). An array of three component velocity and acceleration transducers were placed in two concentric rings entirely surrounding the single shot hole at 150 and 300 azimuths as measured from ground zero. Data from the transducers was then used to determine the average propagation velocity of the blast vibration through the rock mass at the various azimuths. The rock mass was mapped to determine the prominent joint orientations (strike and dip) and the average propagation velocities were correlated with this geologic information. The data from these experiments shows that there is a correlation between the orientation of prominent joints and the average velocity of ground motion. It is theorized that this relationship is due to the relative path the ground wave follows when encountering a joint or structure within the rock mass. The more prominent structures allow the wave to follow along their strike thereby forming a sort of channel or path of least resistance and in turn increasing the propagation velocity. Secondary joints or structures may act in concert with more prominent features to form a network of channels along which the wave moves more freely than it may travel against the structure. The amplitudes of the ground motion was also shown to vary azimuthally with the direction of the most prominent structures.

  14. Structures of glide-set 90 deg. partial dislocation cores in diamond cubic semiconductors

    Beckman, S.P.; Chrzan, D.C.

    2003-01-01

    Two core reconstructions of the 90 deg. partial dislocations in diamond cubic semiconductors, the so-called single- and double-period structures, are often found to be nearly degenerate in energy. This near degeneracy suggests the possibility that both core reconstructions may be present simultaneously along the same dislocation core, with the domain sizes of the competing reconstructions dependent on temperature and the local stress state. To explore this dependence, a simple statistical mechanics-based model of the dislocation core reconstructions is developed and analyzed. Predictions for the temperature-dependent structure of the dislocation core are presented

  15. STRCMACS: An extensive set of Macros for structured programming in OS/360 assembly language

    Barth, C. W.

    1974-01-01

    Two techniques are discussed that have been most often referred to as structured programming. One is that of programming with high level control structures (such as the if and while) replacing the branch instruction (goto-less programming); the other is the process of developing a program by progressively refining descriptions of components in terms of more primitive components (called stepwise refinement or top-down programming). In addition to discussing what these techniques are, it is shown why their use is advised and how both can be implemented in OS assembly language by the use of a special macro instruction package.

  16. Leadership = Communication? The Relations of Leaders' Communication Styles with Leadership Styles, Knowledge Sharing and Leadership Outcomes.

    de Vries, Reinout E; Bakker-Pieper, Angelique; Oostenveld, Wyneke

    2010-09-01

    PURPOSE: The purpose of this study was to investigate the relations between leaders' communication styles and charismatic leadership, human-oriented leadership (leader's consideration), task-oriented leadership (leader's initiating structure), and leadership outcomes. METHODOLOGY: A survey was conducted among 279 employees of a governmental organization. The following six main communication styles were operationalized: verbal aggressiveness, expressiveness, preciseness, assuredness, supportiveness, and argumentativeness. Regression analyses were employed to test three main hypotheses. FINDINGS: In line with expectations, the study showed that charismatic and human-oriented leadership are mainly communicative, while task-oriented leadership is significantly less communicative. The communication styles were strongly and differentially related to knowledge sharing behaviors, perceived leader performance, satisfaction with the leader, and subordinate's team commitment. Multiple regression analyses showed that the leadership styles mediated the relations between the communication styles and leadership outcomes. However, leader's preciseness explained variance in perceived leader performance and satisfaction with the leader above and beyond the leadership style variables. IMPLICATIONS: This study offers potentially invaluable input for leadership training programs by showing the importance of leader's supportiveness, assuredness, and preciseness when communicating with subordinates. ORIGINALITY/VALUE: Although one of the core elements of leadership is interpersonal communication, this study is one of the first to use a comprehensive communication styles instrument in the study of leadership.

    E. B. Chabina

    2016-01-01

    Full Text Available Relevance of research: There are two sizes (several microns and nanodimensional of strengthening j'-phase in single-crystal heat resisting nickel and intermetallic alloys, used for making blades of modern gas turbine engines (GTD. For in-depth study of structural and phase condition of such alloys not only qualitative description of created structure is necessary, but quantitative analysis of alloy components geometrical characteristics. Purpose of the work: Development of reference material sets of heat resisting nickel and intermetallic alloy composition and structure. Research methods: To address the measurement problem of control of structural and geometrical characteristics of single-crystal heat resisting and intermetallic alloys by analytical microscopy and X-ray diffraction analysis the research was carried out using certified measurement techniques on facilities, entered in the Register of Measurement Means of the Russian Federation. The research was carried out on microsections, foils and plates, cut in the plane {100}. Results: It is established that key parameters, defining the properties of these alloys are particle size of strengthening j' -phase, the layer thickness of j-phase between them and parameters of phases lattice. Metrological requirements for reference materials of composition and structure of heat resisting nickel and intermetallic alloys are formulated. The necessary and sufficient reference material set providing the possibility to determine the composition and structure parameters of single-crystal heat resisting nickel and intermetallic alloys is defined. The developed RM sets are certified as in-plant reference materials. Conclusion: The reference materials can be used for graduation of spectral equipment when conducting element analysis of specified class alloys; for calibration of means of measuring alloy structure parameters; for measurement of alloys phases lattice parameters; for structure reference pictures

  19. Examining the structural challenges to communication as experienced by nurse managers in two US hospital settings.

    Marx, Marcia

    2014-11-01

    This study examined the structural barriers to communication for first-line nurse managers with their staff nurses. The delivery of quality care depends on effective communication in hospital units. First-line nurse managers are central figures in networks whose responsibility is to communicate information from the senior management to staff nurses. The data were collected using face-to-face interviews with first-line managers at two US hospitals The interviews were transcribed and coded with limited use of the qualitative software atlas Interview questions focused on work experiences of managers with special emphases on communication. Structural barriers that influenced managers' communication included the amount of face-to-face interaction with nurses, the amount of information to communicate, levels of formalization, outreach to all nurses, time constraints and nurses' subcultural networks These factors compromised managers' ability to communicate effectively with nurses. Managers should carefully examine how structure affects communication recognizing that some dynamics of structure cannot be changed but that they can influence others, such as formalization and communication networks. Managers should examine their own positioning within nurses' networks and demonstrate to nurses that their expertise contributes to the collaborative capital upon which nursing practice depends. © 2013 John Wiley & Sons Ltd.

    Highlights: • Using the results of EM analysis on the magnetization and the major disruption such as MD-1, MD-2, and MD-IV events, structural analyses are performed with the conventional FEM code (ANSYS). • The obtained stresses and deformations are confirmed to meet the design criteria. • We found that the magnetization effect is dominant compared to the major disruptions. - Abstract: Using a conceptual design of the Korean helium cooled ceramic reflector (HCCR) test blanket module (TBM) including the TBM-shield for testing in ITER, a structural analysis with electro-magnetic (EM) loads is performed. From a previous analysis of the material magnetization due to the use of reduced activation ferritic-martensitic (RAFM) steel as the TBM structure material and EM analysis considering the major disruption of MD-I, MD-II, and MD-IV, the forces are obtained and used for the current structural analysis. The results indicate that the maximum stress occurs at the He purge line at the upper and lower region of the breeding zone (BZ) box including the graphite reflector region, which meets the design requirement. In addition, displacements are lower than the designed gaps from the TBM port plug (PP) frame. The results are provided to the load combination analysis.

In addition, displacements are lower than the designed gaps from the TBM port plug (PP) frame. The results are provided to the load combination analysis.

    Despite the empirical evidence for the power of the cognitive capacity of implicit learning of structures and regularities in several modalities and materials, it remains controversial whether implicit learning extends to the learning of temporal structures and regularities. We investigated whether (a) an artificial grammar can be learned equally well when expressed in duration sequences as when expressed in pitch sequences, (b) learning of the artificial grammar in either duration or pitch (as the primary dimension) sequences can be influenced by the properties of the secondary dimension (invariant vs. randomized), and (c) learning can be boosted when the artificial grammar is expressed in both pitch and duration. After an exposure phase with grammatical sequences, learning in a subsequent test phase was assessed in a grammaticality judgment task. Participants in both the pitch and duration conditions showed incidental (not fully implicit) learning of the artificial grammar when the secondary dimension was invariant, but randomizing the pitch sequence prevented learning of the artificial grammar in duration sequences. Expressing the artificial grammar in both pitch and duration resulted in disproportionately better performance, suggesting an interaction between the learning of pitch and temporal structure. The findings are relevant to research investigating the learning of temporal structures and the learning of structures presented simultaneously in 2 dimensions (e.g., space and time, space and objects). By investigating learning, the findings provide further insight into the potential specificity of pitch and time processing, and their integrated versus independent processing, as previously debated in music cognition research.

    This article describes the conceptual framework for the Coping Power program that has focused on proximal risk factors that can actively alter preadolescent children's aggressive behavior. The results of initial controlled efficacy trials are summarized. However, consistent with the theme of this special section, some clinicians and workshop participants have indicated barriers to the implementation of the Coping Power program in their service settings. In response to these types of concerns, three key areas of programmatic adaptation of the program that serve to address these concerns are then described in the article. First, existing and in-process studies of variations in how the program can be delivered are presented. Existing findings indicate how the child component fares when delivered by itself without the parent component, how simple monthly boosters affect intervention effects, and whether the program can be reduced by a third of its length and still be effective. Research planned or in progress on program variations examines whether group versus individual delivery of the program affects outcomes, whether the program can be adapted for early adolescents, whether the program can be delivered in an adaptive manner with the use of the Family Check Up, and whether a brief, efficient version of the program in conjunction with Internet programming can be developed and be effective. Second, the program has been and is being developed for use in different settings, other than the school-based delivery in the efficacy trials. Research has examined its use with aggressive deaf youth in a residential setting, with Oppositional Defiant Disorder and Conduct Disorder children in outpatient clinics, and in after-school programs. Third, the article reports how variations in training clinicians affect their ability to effectively use the program. PsycINFO Database Record (c) 2012 APA, all rights reserved.

  9. Structural relations of convenience food satisfaction and quality of life according to dietary style: Focusing on singles in metropolitan area of Korea.

    Kim, Boram; Joo, Nami

    2014-10-01

    Although the issues of singles' dietary style and quality of life are becoming important due to the increasing number of singles with economic power, little research has been conducted to date on singles' use of convenience food and quality of life in relation to their dietary style. Thus, the present study intends to provide basic data to improve the quality of life by determining the current status of the use of convenience food and explicating its relationship with quality of life through analyzing the dietary lifestyles of the singles. The targets of this study were singles, identified as adults between the ages of 25 and 54, living alone, either legally or in actuality having no partner. A statistical analysis of 208 surveys from Seoul, respectively, was conducted using SPSS12.0 for Windows and SEM using AMOS 5.0 statistics package. The convenience-oriented was shown to have a significant positive effect on convenience food satisfaction. HMR satisfaction was found to have a significant effect on positive psychological satisfaction and the convenience-oriented was found to have a significant negative effect on all aspects of quality of life satisfaction. There must be persistent development of food industries considering the distinctive characteristics of the lives of singles in order to satisfy their needs and improve the quality of their lives.

  10. Technological Style is History

    Blond, Lasse

    The effort to comprehend innovation across cultures and time highlights the importance of the explicating factors external to technology. It becomes relevant to nuance or differentiate the understanding of social and cultural responses to adopted technologies by recognizing that technology shapes...... culture, and just as importantly that culture shapes technology. By looking at a recent transfer of technology this reciprocal exchange is elaborated by considering the cultural or contextual influence in the adaptation of technology. In this connection the notion of technological style is revisited...... by questioning whether it pays due attention to the non-technical factors of the process? In order to compensate for the deficiencies of the technological style as a sensitizing device the concept of sociotechnical style is introduced – a concept more in tune with resent research in technology studies....

  11. Management styles and motivation.

    Shearer, Dana Ann

    2012-01-01

    According to a review of the current literature, common managerial styles are transformational, transactional, and laissez-faire. When managers expand their leadership skills to improve the staff's morale, they must use a combination of transformational leadership behaviors and transactional contingent rewards to maximize their effectiveness on employees. A motivation theory such as Herzberg and Maslow enhances employees' motivation, morale, and satisfaction. Being able to motivate, empower, and influence staff improves satisfaction and retention levels among the team. A manager's leadership style influences motivation, morale, and retention in staff. Leaders are influenced by their educational development and the organizational culture. Organizational culture has an impact on a manager's style, which is forwarded to their followers.

  12. Structural insights into the regulation and the recognition of histone marks by the SET domain of NSD1

    Morishita, Masayo; Di Luccio, Eric

    2011-01-01

    Highlights: → NSD1, NSD2/MMSET/WHSC1, and NSD3/WHSC1L1 are histone methyltransferases linked to numerous cancers. → Little is known about the NSD pathways and HMTase inhibitors are sorely needed in the epigenetic therapy of cancers. → We investigate the regulation and the recognition of histone marks by the SET domain of NSD1. → A unique and key mechanism is driven by a loop at the interface of the SET and postSET region. → Implications for developing specific and selective HMTase inhibitors are presented. -- Abstract: The development of epigenetic therapies fuels cancer hope. DNA-methylation inhibitors, histone-deacetylase and histone-methyltransferase (HMTase) inhibitors are being developed as the utilization of epigenetic targets is emerging as an effective and valuable approach to chemotherapy as well as chemoprevention of cancer. The nuclear receptor binding SET domain (NSD) protein is a family of three HMTases, NSD1, NSD2/MMSET/WHSC1, and NSD3/WHSC1L1 that are critical in maintaining the chromatin integrity. A growing number of studies have reported alterations or amplifications of NSD1, NSD2, or NSD3 in numerous carcinogenic events. Reducing NSDs activity through specific lysine-HMTase inhibitors appears promising to help suppressing cancer growth. However, little is known about the NSD pathways and our understanding of the histone lysine-HMTase mechanism is partial. To shed some light on both the recognition and the regulation of epigenetic marks by the SET domain of the NSD family, we investigate the structural mechanisms of the docking of the histone-H4 tail on the SET domain of NSD1. Our finding exposes a key regulatory and recognition mechanism driven by the flexibility of a loop at the interface of the SET and postSET region. Finally, we prospect the special value of this regulatory region for developing specific and selective NSD inhibitors for the epigenetic therapy of cancers.

    Geopolymers, obtained by chemical reaction between aluminosilicate oxides and silicates under highly alkaline conditions, are studied in this paper. The proposed mechanism of geopolymer setting and hardening or curing consists of a dissolution, a transportation or an orientation, as well as a polycondensation step. The aim of this paper is to investigate the influence of the curing time and temperature, the relative humidity and the reagents temperature on the geopolymerization process in order to obtain a resistant matrix usable for inertization of hazardous wastes. The evolution of the process from the precursors dissolution to final geopolymer matrix hardening has been followed by FTIR spectroscopy, X-ray diffractometry, SEM/EDS and leaching tests. The results show the significant influence of both curing temperature in the curing stage and of the mould materials on the matrix stability. The easy-to-run preparation procedure for a chemically stable metakaolin geopolymer individuated can be summarized as reagents setting and curing at room temperature and material mould which permits moisture level around 40%. - Graphical abstract: Chemical stability as a function of curing conditions. Highlights: ► Metakaolin in highly alkaline solutions produced solid materials at room temperature. ► Curing time and temperature, relative humidity, reagents temperature were optimized. ► Leaching tests were used to confirm final hardening. ► FTIR spectroscopy, SEM analysis and X-ray diffractometry were used to interpret matrix stability.

  15. Negative hallucinations, dreams and hallucinations: The framing structure and its representation in the analytic setting.

    Perelberg, Rosine Jozef

    2016-12-01

    This paper explores the meaning of a patient's hallucinatory experiences in the course of a five times a week analysis. I will locate my understanding within the context of André Green's ideas on the role of the framing structure and the negative hallucination in the structuring of the mind. The understanding of the transference and countertransference was crucial in the creation of meaning and enabling the transformations that took place in the analytic process. Through a detailed analysis of a clinical example the author examines Bion's distinction between hysterical hallucinations and psychotic hallucinations and formulates her own hypothesis about the distinctions between the two. The paper suggests that whilst psychotic hallucinations express a conflict between life and death, in the hysterical hallucination it is between love and hate. The paper also contains some reflections on the dramatic nature of the analytic encounter. Copyright © 2016 Institute of Psychoanalysis.

  16. Numerical seismic modelling of fault-fold structures in a mountainous setting

    Kirtland Grech, M.G.; Lawton, D.C.; Spratt, D.A. (Calgary Univ., AB (Canada))

    1999-01-01

    Experiments were conducted to determine the performance of different prestack migration algorithms in complex structural areas, particularly in the presence of rugged topography and thrust faults that result in severe lateral and vertical velocity changes, using a series of numerical seismic models. The numerical model used was based on a cross section through the Rocky Mountains Front Ranges of Western Canada and is 33 km wide and 11 km deep. The best migrated section was obtained with FD shot migration in depth and from topography, using the known velocity model. This result was superior to Kirchhoff depth migration from topography and from a flat datum. As the velocities departed from their true value, the deeper events were most affected, because of the accumulation of velocity errors with depth. The small-scale features of Target A, in the shallower part of the section, could still be interpreted even when the velocities were inaccurate. In the presence of velocity errors, the different structures could still be interpreted, but were at the wrong depth and had the wrong structural shape and size. Layers that were of the order of 1 km in width and 500 km in thickness, such as Layer 4, were the most poorly imaged and focussed, both with time migration and with depth migration. Fault planes were not imaged in the absence of a velocity contrast across them, making some FW cutoffs difficult to interpret. 2 refs.

  18. Mathematical modeling of vibration processes in reinforced concrete structures for setting up crack initiation monitoring

    2015-03-01

    The contemporary construction industry is based on the use of reinforced concrete structures, but emergency situations resulting in fracture can arise in their exploitation. In a majority of cases, reinforced concrete fracture is realized as the process of crack formation and development. As a rule, the appearance of the first cracks does not lead to the complete loss of the carrying capacity but is a fracture precursor. One method for ensuring the safe operation of building structures is based on crack initiation monitoring. A vibration method for the monitoring of reinforced concrete structures is justified in this paper. An example of a reinforced concrete beam is used to consider all stages related to the analysis of the behavior of natural frequencies in the development of a crack-shaped defect and the use of the obtained numerical results for the vibration test method. The efficiency of the method is illustrated by the results of modeling of the physical part of the method related to the analysis of the natural frequency evolution as a response to the impact action in the crack development process.

    International audience; Considering a linearly ordered set, we introduce its symmetric version, and endow it with two operations extending supremum and infimum, so as to obtain an algebraic structure close to a commutative ring. We show that imposing symmetry necessarily entails non associativity, hence computing rules are defined in order to deal with non associativity. We study in details computing rules, which we endow with a partial order. This permits to find solutions to the inversion f...

  1. Ab initio localized basis set study of structural parameters and elastic properties of HfO2 polymorphs

    Caravaca, M A; Casali, R A

    2005-01-01

    The SIESTA approach based on pseudopotentials and a localized basis set is used to calculate the electronic, elastic and equilibrium properties of P 2 1 /c, Pbca, Pnma, Fm3m, P4 2 nmc and Pa3 phases of HfO 2 . Using separable Troullier-Martins norm-conserving pseudopotentials which include partial core corrections for Hf, we tested important physical properties as a function of the basis set size, grid size and cut-off ratio of the pseudo-atomic orbitals (PAOs). We found that calculations in this oxide with the LDA approach and using a minimal basis set (simple zeta, SZ) improve calculated phase transition pressures with respect to the double-zeta basis set and LDA (DZ-LDA), and show similar accuracy to that determined with the PPPW and GGA approach. Still, the equilibrium volumes and structural properties calculated with SZ-LDA compare better with experiments than the GGA approach. The bandgaps and elastic and structural properties calculated with DZ-LDA are accurate in agreement with previous state of the art ab initio calculations and experimental evidence and cannot be improved with a polarized basis set. These calculated properties show low sensitivity to the PAO localization parameter range between 40 and 100 meV. However, this is not true for the relative energy, which improves upon decrease of the mentioned parameter. We found a non-linear behaviour in the lattice parameters with pressure in the P 2 1 /c phase, showing a discontinuity of the derivative of the a lattice parameter with respect to external pressure, as found in experiments. The common enthalpy values calculated with the minimal basis set give pressure transitions of 3.3 and 10.8?GPa for P2 1 /c → Pbca and Pbca → Pnma, respectively, in accordance with different high pressure experimental values

  3. Leadership styles in nursing.

    Cope, Vicki; Murray, Melanie

    2017-06-21

    Nurses are often asked to think about leadership, particularly in times of rapid change in healthcare, and where questions have been raised about whether leaders and managers have adequate insight into the requirements of care. This article discusses several leadership styles relevant to contemporary healthcare and nursing practice. Nurses who are aware of leadership styles may find this knowledge useful in maintaining a cohesive working environment. Leadership knowledge and skills can be improved through training, where, rather than having to undertake formal leadership roles without adequate preparation, nurses are able to learn, nurture, model and develop effective leadership behaviours, ultimately improving nursing staff retention and enhancing the delivery of safe and effective care.

    Many nursing schools and health care journals have adopted the Publication Manual of the American Psychological Association (APA stylebook) as their guide to achieve uniformity and consistency in manuscript preparation as well as in usage and writing style. Published in 2001, the fifth edition of the APA stylebook contains 440 pages and can overwhelm someone who tries to use it for the first time. This article delineates main points in the areas of manuscript preparation, reference lists, in-text citations, and style choices.

  5. Basis set construction for molecular electronic structure theory: natural orbital and Gauss-Slater basis for smooth pseudopotentials.

    Petruzielo, F R; Toulouse, Julien; Umrigar, C J

    2011-02-14

    A simple yet general method for constructing basis sets for molecular electronic structure calculations is presented. These basis sets consist of atomic natural orbitals from a multiconfigurational self-consistent field calculation supplemented with primitive functions, chosen such that the asymptotics are appropriate for the potential of the system. Primitives are optimized for the homonuclear diatomic molecule to produce a balanced basis set. Two general features that facilitate this basis construction are demonstrated. First, weak coupling exists between the optimal exponents of primitives with different angular momenta. Second, the optimal primitive exponents for a chosen system depend weakly on the particular level of theory employed for optimization. The explicit case considered here is a basis set appropriate for the Burkatzki-Filippi-Dolg pseudopotentials. Since these pseudopotentials are finite at nuclei and have a Coulomb tail, the recently proposed Gauss-Slater functions are the appropriate primitives. Double- and triple-zeta bases are developed for elements hydrogen through argon. These new bases offer significant gains over the corresponding Burkatzki-Filippi-Dolg bases at various levels of theory. Using a Gaussian expansion of the basis functions, these bases can be employed in any electronic structure method. Quantum Monte Carlo provides an added benefit: expansions are unnecessary since the integrals are evaluated numerically.

  6. The connection-set algebra--a novel formalism for the representation of connectivity structure in neuronal network models.

    Djurfeldt, Mikael

    2012-07-01

    The connection-set algebra (CSA) is a novel and general formalism for the description of connectivity in neuronal network models, from small-scale to large-scale structure. The algebra provides operators to form more complex sets of connections from simpler ones and also provides parameterization of such sets. CSA is expressive enough to describe a wide range of connection patterns, including multiple types of random and/or geometrically dependent connectivity, and can serve as a concise notation for network structure in scientific writing. CSA implementations allow for scalable and efficient representation of connectivity in parallel neuronal network simulators and could even allow for avoiding explicit representation of connections in computer memory. The expressiveness of CSA makes prototyping of network structure easy. A C+ + version of the algebra has been implemented and used in a large-scale neuronal network simulation (Djurfeldt et al., IBM J Res Dev 52(1/2):31-42, 2008b) and an implementation in Python has been publicly released.

  7. Details Matter: Noise and Model Structure Set the Relationship between Cell Size and Cell Cycle Timing

    Felix Barber

    2017-11-01

    Full Text Available Organisms across all domains of life regulate the size of their cells. However, the means by which this is done is poorly understood. We study two abstracted “molecular” models for size regulation: inhibitor dilution and initiator accumulation. We apply the models to two settings: bacteria like Escherichia coli, that grow fully before they set a division plane and divide into two equally sized cells, and cells that form a bud early in the cell division cycle, confine new growth to that bud, and divide at the connection between that bud and the mother cell, like the budding yeast Saccharomyces cerevisiae. In budding cells, delaying cell division until buds reach the same size as their mother leads to very weak size control, with average cell size and standard deviation of cell size increasing over time and saturating up to 100-fold higher than those values for cells that divide when the bud is still substantially smaller than its mother. In budding yeast, both inhibitor dilution or initiator accumulation models are consistent with the observation that the daughters of diploid cells add a constant volume before they divide. This “adder” behavior has also been observed in bacteria. We find that in bacteria an inhibitor dilution model produces adder correlations that are not robust to noise in the timing of DNA replication initiation or in the timing from initiation of DNA replication to cell division (the C+D period. In contrast, in bacteria an initiator accumulation model yields robust adder correlations in the regime where noise in the timing of DNA replication initiation is much greater than noise in the C + D period, as reported previously (Ho and Amir, 2015. In bacteria, division into two equally sized cells does not broaden the size distribution.

    2012-01-01

    We develop a theory of intergenerational transmission of preferences that rationalizes the choice between alternative parenting styles (as set out in Baumrind 1967). Parents maximize an objective function that combines Beckerian altruism and paternalism towards children. They can affect their children's choices via two channels: either by influencing children's preferences or by imposing direct restrictions on their choice sets. Different parenting styles (authoritarian, authoritative, and pe...

  11. Structural basis for inhibition of the histone chaperone activity of SET/TAF-Iβ by cytochrome c.

    González-Arzola, Katiuska; Díaz-Moreno, Irene; Cano-González, Ana; Díaz-Quintana, Antonio; Velázquez-Campoy, Adrián; Moreno-Beltrán, Blas; López-Rivas, Abelardo; De la Rosa, Miguel A

    2015-08-11

    Chromatin is pivotal for regulation of the DNA damage process insofar as it influences access to DNA and serves as a DNA repair docking site. Recent works identify histone chaperones as key regulators of damaged chromatin's transcriptional activity. However, understanding how chaperones are modulated during DNA damage response is still challenging. This study reveals that the histone chaperone SET/TAF-Iβ interacts with cytochrome c following DNA damage. Specifically, cytochrome c is shown to be translocated into cell nuclei upon induction of DNA damage, but not upon stimulation of the death receptor or stress-induced pathways. Cytochrome c was found to competitively hinder binding of SET/TAF-Iβ to core histones, thereby locking its histone-binding domains and inhibiting its nucleosome assembly activity. In addition, we have used NMR spectroscopy, calorimetry, mutagenesis, and molecular docking to provide an insight into the structural features of the formation of the complex between cytochrome c and SET/TAF-Iβ. Overall, these findings establish a framework for understanding the molecular basis of cytochrome c-mediated blocking of SET/TAF-Iβ, which subsequently may facilitate the development of new drugs to silence the oncogenic effect of SET/TAF-Iβ's histone chaperone activity.

  12. Seismic Structural Setting of Western Farallon Basin, Southern Gulf of California, Mexico.

    Pinero-Lajas, D.; Gonzalez-Fernandez, A.; Lopez-Martinez, M.; Lonsdale, P.

    2007-05-01

    Data from a number of high resolution 2D multichannel seismic (MCS) lines were used to investigate the structure and stratigraphy of the western Farallon basin in the southern Gulf of California. A Generator-Injector air gun provided a clean seismic source shooting each 12 s at a velocity of 6 kts. Each signal was recorded during 6- 8 s, at a sampling interval of 1 ms, by a 600 m long digital streamer with 48 channels and a spacing of 12.5 m. The MCS system was installed aboard CICESE's (Centro de Investigacion Cientifica y de Educacion Superior de Ensenada) 28 m research vessel Francisco de Ulloa. MCS data were conventionally processed, to obtain post- stack time-migrated seismic sections. The MCS seismic sections show a very detailed image of the sub-bottom structure up to 2-3 s two-way travel time (aprox. 2 km). We present detailed images of faulting based on the high resolution and quality of these data. Our results show distributed faulting with many active and inactive faults. Our study also constrains the depth to basement near the southern Baja California eastern coast. The acoustic basement appears as a continuous feature in the western part of the study area and can be correlated with some granite outcrops located in the southern Gulf of California islands. To the East, near the center of the Farallon basin, the acoustic basement changes, it is more discontinuous, and the seismic sections show a number of diffracted waves.

    Degenerative aortic stenosis has become a common and dangerous disease in recent decades. This disease leads to the mineralization of aortic valves, their gradual thickening and loss of functionality. We studied the detailed assessment of the proportion and composition of inorganic and organic components in the ossified aortic valve, using a set of analytical methods applied in science: polarized light microscopy, scanning electron microscopy, X-ray fluorescence, X-ray diffraction, gas chromatography/mass spectrometry and liquid chromatography-tandem mass spectrometry. The sample valves showed the occurrence of phosphorus and calcium in the form of phosphate and calcium carbonate, hydroxyapatite, fluorapatite and hydroxy-fluorapatite, with varying content of inorganic components from 65 to 90 wt%, and with phased development of degenerative disability. The outer layers of the plaque contained an organic component with peptide bonds, fatty acids, proteins and cholesterol. The results show a correlation between the formation of fluorapatite in aortic valves and in other parts of the human bodies, associated with the formation of bones.

  15. Setting up an ethics of ecosystem research structure based on the precautionary principle.

    Farmer, Michael C

    2013-01-01

    Ethical practices in ecological field research differ from those in laboratory research in more than the technical setting and the important distinction between population-level and individual-based concerns. The number of stakeholders affected by the conduct of field research is far larger; private landholders, public water utilities, public land managers, local industries, and communities large and small are only some of those who may be impacted. As research review boards move to establish specific ethical practices for field biologists, the process of identifying appropriate standards will affect the degree to which research will ultimately be disrupted. Standards that lead to research protocols that alienate key interests are not likely to be sustainable. Already, standards that have conflicted with the primary values of a key interest have resulted in disruptions to research and scientific progress. One way to manage this problem of deeply competing interests is to avoid the deepest offenses to any relevant interest group in the design of a proposed study. This is an application of the precautionary principle and is likely to generate a more sustainable balance among competing interests. Unfortunately, this process is also likely to be a never-ending, consensus-seeking process. Fortunately, scientists can have enormous influence on the process if they choose to engage in it early. If scientists use their expertise to function as honest brokers among affected interests, their own interest in scientific research progress is likely to be better met.

  16. African electricity market liberalization, competition and structuring: Should double bid markets be set up?

    Founanou, M.

    2011-01-01

    In this paper, we analyse the possibility of using double auction mechanisms in the organization of the electricity markets in African countries. Today's electricity markets around the world are de-regulated and going through a restructuring process. In a context marked by the opening up to competition, a double auction for electricity supply is henceforth used to set prices in wholesale and retail electricity markets. Game theory analysis useful for studying the double auction prices proprieties. The double auction is a non-cooperative game, which is strategically equivalent to the auctions theory. The price formed, depending on the buyers and sellers' strategies, is a competitive price, which tends to the ideal price when competition operates intensely on both sides of market. For Africa, the presence of congestion costs and a chronic lack of capacity require the search for other solutions. We investigate optimal strategic behaviour when buyers and sellers are separated by a possibly constrained transmission line and show that bidders' strategies converge to truth-telling behaviour as the number of market participants increases. In the congestion case, this fails to occur. We also investigate how participants in wholesale electricity markets modify their bidding strategies as a function of the influence and behaviour of a transmission line owner. (author)

  17. Style as Supplement - Supplement as Style

    Sørensen, Bent

    The film Derrida by Amy Ziering Kofman & Kirby Dick (2003) has a memorable scene, showing Derrida watching Derrida watching Derrida. This regression, almost ad infinitum, would seem to have the specific purpose to hammer home the point to the viewer of the film that all communication is mediated......, and to aim for an almost Brechtian Verfremdung-effect, but the film also uses this device as a stylistic trait to characterize something ‘essential' about Derrida and his style. Derrida strikes the same chord by insisting on drawing attention to the artificiality of the making of the film, where questions...... have to be repeated and answers interrupted when the light or the sound is not just right. He furthermore deconstructs the interview process by constantly referring to the impossibility of answering questions without specific contexts, frames and grounds. This makes it easy to characterize the film...

  3. Ownership Structure, Earnings Management and Investment Opportunity Set: Evidence from Mexican Firms

    Juan M. San Martin-Reyna

    2012-01-01

    Full Text Available This paper analyses the influence of ownership, board of directors, and financial leverage on companies’ performance when these either face, or do not face, profitable growth opportunities. Towards that end we examined a sample of 83 listed Mexican firms during the period 2005-2011. The results confirm the relevance of debt and board of directors in terms of firm market value by showing a negative relationship between performance and both, board of directors and leverage, in the presence of growth opportunities. In contrast, the relationship between debt and performance becomes positive when firms have no profitable investment projects. The results also demonstrate that the relevance of controlling shareholders on firm value is different when firms have or not growth opportunities. Therefore, our results show that ownership structure, composition and size of board and the level of leverage play a dual role on performance (increase or decrease the firm value and determinewhether the firms have profitable investment projects.

  4. Multigrid on unstructured grids using an auxiliary set of structured grids

    Douglas, C.C.; Malhotra, S.; Schultz, M.H. [Yale Univ., New Haven, CT (United States)

    1996-12-31

    Unstructured grids do not have a convenient and natural multigrid framework for actually computing and maintaining a high floating point rate on standard computers. In fact, just the coarsening process is expensive for many applications. Since unstructured grids play a vital role in many scientific computing applications, many modifications have been proposed to solve this problem. One suggested solution is to map the original unstructured grid onto a structured grid. This can be used as a fine grid in a standard multigrid algorithm to precondition the original problem on the unstructured grid. We show that unless extreme care is taken, this mapping can lead to a system with a high condition number which eliminates the usefulness of the multigrid method. Theorems with lower and upper bounds are provided. Simple examples show that the upper bounds are sharp.

  5. How coping styles, cognitive distortions, and attachment predict problem gambling among adolescents and young adults.

    Calado, Filipa; Alexandre, Joana; Griffiths, Mark D

    2017-12-01

    Background and aims Recent research suggests that youth problem gambling is associated with several factors, but little is known how these factors might influence or interact each other in predicting this behavior. Consequently, this is the first study to examine the mediation effect of coping styles in the relationship between attachment to parental figures and problem gambling. Methods A total of 988 adolescents and emerging adults were recruited to participate. The first set of analyses tested the adequacy of a model comprising biological, cognitive, and family variables in predicting youth problem gambling. The second set of analyses explored the relationship between family and individual variables in problem gambling behavior. Results The results of the first set of analyses demonstrated that the individual factors of gender, cognitive distortions, and coping styles showed a significant predictive effect on youth problematic gambling, and the family factors of attachment and family structure did not reveal a significant influence on this behavior. The results of the second set of analyses demonstrated that the attachment dimension of angry distress exerted a more indirect influence on problematic gambling, through emotion-focused coping style. Discussion This study revealed that some family variables can have a more indirect effect on youth gambling behavior and provided some insights in how some factors interact in predicting problem gambling. Conclusion These findings suggest that youth gambling is a multifaceted phenomenon, and that the indirect effects of family variables are important in estimating the complex social forces that might influence adolescent decisions to gamble.

  6. Put Your Style at Stake

    Johnsen, Christian Garmann; Olaison, Lena; Meier Sørensen, Bent

    2018-01-01

    This article uses the concept of style to rethink sustainable entrepreneurship. Our point of departure is the conceptual distinction between organization as style made durable and entrepreneurship as the disruption of style. We show that style is not simply an aesthetic category, but rather what...... enable the creation of new styles. In order to conceptualize this creative process, we explore how play can create disharmonies within the organization, but we also maintain that any new practice will remain marginal without a collective assemblage capable of adopting it. On this basis, we argue...... that sustainable entrepreneurship consists of making an environmentally friendly and socially conscious style durable, but also of disrupting such a style. In order to illustrate our argument, we use the example of the sustainable smartphone producer Fairphone. In conclusion, we argue that the concept of style may...

  7. Identity style and coping strategies.

    Berzonsky, M D

    1992-12-01

    This study examined the relationship between identity style and strategies used to cope with stressors that potentially threaten one's sense of identity. Identity style refers to differences in the way individuals construct and revise or maintain their sense of identity. An informational style involves actively seeking out, evaluating, and utilizing self-relevant information. A normative style highlights the expectations and standards of significant others. A diffuse/avoidant style is characterized by procrastination and situation-specific reactions. Late-adolescent college subjects were administered measures of identity style, ways of coping with academic stressors, and test anxiety. Within this self-as-student context, subjects with diffuse and normative identity styles employed avoidant-oriented coping strategies (wishful thinking, distancing, and tension reduction). An informational style was associated with deliberate, problem-focused coping. Findings are discussed in terms of a process model of identity development.

  9. A statistical method for predicting sound absorbing property of porous metal materials by using quartet structure generation set

    Guan, Dong; Wu, Jiu Hui; Jing, Li

    2015-01-01

    Highlights: • A random internal morphology and structure generation-growth method, termed as the quartet structure generation set (QSGS), has been utilized based on the stochastic cluster growth theory for numerical generating the various microstructures of porous metal materials. • Effects of different parameters such as thickness and porosity on sound absorption performance of the generated structures are studied by the present method, and the obtained results are validated by an empirical model as well. • This method could be utilized to guide the design and fabrication of the sound-absorption porous metal materials. - Abstract: In this paper, a statistical method for predicting sound absorption properties of porous metal materials is presented. To reflect the stochastic distribution characteristics of the porous metal materials, a random internal morphology and structure generation-growth method, termed as the quartet structure generation set (QSGS), has been utilized based on the stochastic cluster growth theory for numerical generating the various microstructures of porous metal materials. Then by using the transfer-function approach along with the QSGS tool, we investigate the sound absorbing performance of porous metal materials with complex stochastic geometries. The statistical method has been validated by the good agreement among the numerical results for metal rubber from this method and a previous empirical model and the corresponding experimental data. Furthermore, the effects of different parameters such as thickness and porosity on sound absorption performance of the generated structures are studied by the present method, and the obtained results are validated by an empirical model as well. Therefore, the present method is a reliable and robust method for predicting the sound absorption performance of porous metal materials, and could be utilized to guide the design and fabrication of the sound-absorption porous metal materials

  10. The role of crystal structure and fabrics in early diagenesis: examples from continental and marine settings

    Frisia, Silvia; Borsato, Andrea; Bajo, Petra; Hellstrom, John

    2015-04-01

    previously documented in marine facies. In speleothems, the process comes to a halt if the flow of the diagenetic fluid stops, which commonly happens when a new "impermeable" layer is formed atop the partially replaced aragonite. Yet, if dripwaters are allowed to percolate through crystal boundaries, the aragonite below can be completely replaced by a mosaic of calcite and geochemical properties re-set. Preservation of the original fabric, or part of it, is then influenced by both the "exhaustion" of the diagenetic fluid and the presence of organic carbon surfaces. Speleothem diagenetic pathways are not dissimilar to what occurs in the marine environment. Primary and early diagenetic dolomites seem to be preserved in some Triassic sabkha facies, being "protected" by clay or organic layers. In other "early diagenetic dolomites", such as the case of the Early Pliocene makatea reef terraces (Cook Islands, South Pacific), original, highly porous facies were replaced by a mosaic of fabric-destructive dolomite with a few relicts of organic-rich micrite. Thus, original fabric and porosity, crystal defects, crystal boundaries and presence of organic matter in carbonates dictate the diagenetic pathways, while the composition of the diagenetic fluids and the duration of the diagenetic process control the extent of geochemical re-setting of the system.

  12. Electrical structure and its implication across the lower- and upper-crustal settings of South India

    Raval, U.

    1988-01-01

    Measurements of a large scale MMA experiment covering both the granulite and greenstone terrains of Archeans in the southern part of India is re-visited and re-analyzed. The induced field variations contain the signatures of crustal and subcrustal electrical conductivities, although substantially distorted by the sea-land interfaces and cenozoic sediments. However, through a selection of some reconnaissance profiles and temporal variations, an attempt is made to deduce whether: (1) significant differences exist between the electrical structures of the high and low grade complexes (i.e., if the electrical conductivity of the lower crust is due to minerological composition or is intrinsic to the positioning at depths greater than 15 km); (2) the probable seaward extension of the continental crust and its transition to oceanic type may also contribute (through intracrustal DC-like telluric sheets) to the induction field in addition to or rather than the sharply localized zones; (3) the observed parameters are indicative of a formal anisotropy and/or undulations in the deep crust; and (4) the postulate of relatively hotter Indian shield is reflected particularly with regard to differential metamorphism. In the last case, the crust-mantle coupling in this region - unlike other similar areas - seems to be markedly affected by the evolution of Ne-plate velocity field.

    Previous studies have identified a predominant learning style in trainees from different specialties, more recently in otolaryngology residents. The purpose of our study was to determine a predominant learning style within otolaryngology fellowships and to identify any differences between otolaryngology fellows and residents. We conducted a survey of otolaryngology fellows at 25 otolaryngology fellowship programs accredited by the Accreditation Council for Graduate Medical Education. We emailed Kolb's Learning Style Index version 3.1 to 16 pediatric otolaryngology (PO) and 24 otology/neurotology (ON) fellows. This index is a widely used 12-item questionnaire. The participants answered each item in the questionnaire as it applied to their preferred learning style: accommodating, converging, diverging, or assimilating. Results were then analyzed and compared between each subspecialty and the previously reported preferred styles of otolaryngology residents. Ten PO and 20 ON fellows completed the survey, with an overall response rate of 75%. PO and ON fellows (60% of each group) preferred a learning style that was "balanced" across all four styles. For ON fellows, 35% preferred converging and 5% preferred accommodating styles. For PO fellows, converging and accommodating styles accounted for 20% each. It was previously reported that 74.4% of otolaryngology residents prefer either converging or accommodating styles. We believe that the fellowship training environment calls for fellows to use more than one learning style to become proficient physicians, hence the trend toward potentially developing a balanced style when at this level.

  18. Capturing a Commander's decision making style

    Santos, Eugene; Nguyen, Hien; Russell, Jacob; Kim, Keumjoo; Veenhuis, Luke; Boparai, Ramnjit; Stautland, Thomas Kristoffer

    2017-05-01

    A Commander's decision making style represents how he weighs his choices and evaluates possible solutions with regards to his goals. Specifically, in the naval warfare domain, it relates the way he processes a large amount of information in dynamic, uncertain environments, allocates resources, and chooses appropriate actions to pursue. In this paper, we describe an approach to capture a Commander's decision style by creating a cognitive model that captures his decisionmaking process and evaluate this model using a set of scenarios using an online naval warfare simulation game. In this model, we use the Commander's past behaviors and generalize Commander's actions across multiple problems and multiple decision making sequences in order to recommend actions to a Commander in a manner that he may have taken. Our approach builds upon the Double Transition Model to represent the Commander's focus and beliefs to estimate his cognitive state. Each cognitive state reflects a stage in a Commander's decision making process, each action reflects the tasks that he has taken to move himself closer to a final decision, and the reward reflects how close he is to achieving his goal. We then use inverse reinforcement learning to compute a reward for each of the Commander's actions. These rewards and cognitive states are used to compare between different styles of decision making. We construct a set of scenarios in the game where rational, intuitive and spontaneous decision making styles will be evaluated.

    Gowda Cholenahalli LL

    2008-10-01

    Full Text Available Abstract Background Plant genetic resources (PGR are the basic raw materials for future genetic progress and an insurance against unforeseen threats to agricultural production. An extensive characterization of PGR provides an opportunity to dissect structure, mine allelic variations, and identify diverse accessions for crop improvement. The Generation Challenge Program http://www.generationcp.org conceptualized the development of "composite collections" and extraction of "reference sets" from these for more efficient tapping of global crop-related genetic resources. In this study, we report the genetic structure, diversity and allelic richness in a composite collection of chickpea using SSR markers, and formation of a reference set of 300 accessions. Results The 48 SSR markers detected 1683 alleles in 2915 accessions, of which, 935 were considered rare, 720 common and 28 most frequent. The alleles per locus ranged from 14 to 67, averaged 35, and the polymorphic information content was from 0.467 to 0.974, averaged 0.854. Marker polymorphism varied between groups of accessions in the composite collection and reference set. A number of group-specific alleles were detected: 104 in Kabuli, 297 in desi, and 69 in wild Cicer; 114 each in Mediterranean and West Asia (WA, 117 in South and South East Asia (SSEA, and 10 in African region accessions. Desi and kabuli shared 436 alleles, while wild Cicer shared 17 and 16 alleles with desi and kabuli, respectively. The accessions from SSEA and WA shared 74 alleles, while those from Mediterranean 38 and 33 alleles with WA and SSEA, respectively. Desi chickpea contained a higher proportion of rare alleles (53% than kabuli (46%, while wild Cicer accessions were devoid of rare alleles. A genotype-based reference set captured 1315 (78% of the 1683 composite collection alleles of which 463 were rare, 826 common, and 26 the most frequent alleles. The neighbour-joining tree diagram of this reference set represents

  20. A systematic review of structured versus non-structured breastfeeding programmes to support the initiation and duration of exclusive breastfeeding in acute and primary healthcare settings.

    Beake, Sarah; Pellowe, Carol; Dykes, Fiona; Schmied, Virginia; Bick, Debra

    2011-01-01

    Background: Breastfeeding has many important health benefits for the woman and her baby. Despite evidence of benefit from a large number of well conducted studies, breastfeeding uptake and the duration of exclusive breastfeeding remain low in many countries. In order to improve breastfeeding rates, policy and guidelines at global, individual country level and in local healthcare settings have recommended that structured programmes to support breastfeeding should be introduced. The objective of this review was to consider the evidence of outcomes of structured compared with non-structured breastfeeding programmes in acute maternity care settings to support initiation and duration of exclusive breastfeeding. The definition of structured programme used included a multi-faceted or single intervention approach to support breastfeeding; definition of non-structured included support offered within standard care. The review considered quantitative and qualitative studies which addressed outcomes following the introduction of a structured programme in acute healthcare settings to support breastfeeding compared with no programme. The primary outcomes of interest were uptake of breastfeeding and duration of exclusive breastfeeding (only breast milk, including milk expressed). Studies which only considered community based interventions were not included. A search of the literature published between 1992 and 2010 was conducted, which followed a four step process. After a limited search of MEDLINE and CINAHL to identify key words contained in the title or abstract and index terms to describe relevant interventions, a second extensive search was undertaken using identified key words and index terms. The third step included a search of reference lists and bibliographies of relevant articles and the fourth step included a search of grey and unpublished literature and national databasesMethodological quality: Methodological quality was assessed using checklists developed by the

  2. Longwing (Heliconius) butterflies combine a restricted set of pigmentary and structural coloration mechanisms.

    Wilts, Bodo D; Vey, Aidan J M; Briscoe, Adriana D; Stavenga, Doekele G

    2017-11-21

    Longwing butterflies, Heliconius sp., also called heliconians, are striking examples of diversity and mimicry in butterflies. Heliconians feature strongly colored patterns on their wings, arising from wing scales colored by pigments and/or nanostructures, which serve as an aposematic signal. Here, we investigate the coloration mechanisms among several species of Heliconius by applying scanning electron microscopy, (micro)spectrophotometry, and imaging scatterometry. We identify seven kinds of colored scales within Heliconius whose coloration is derived from pigments, nanostructures or both. In yellow-, orange- and red-colored wing patches, both cover and ground scales contain wavelength-selective absorbing pigments, 3-OH-kynurenine, xanthommatin and/or dihydroxanthommatin. In blue wing patches, the cover scales are blue either due to interference of light in the thin-film lower lamina (e.g., H. doris) or in the multilayered lamellae in the scale ridges (so-called ridge reflectors, e.g., H. sara and H. erato); the underlying ground scales are black. In the white wing patches, both cover and ground scales are blue due to their thin-film lower lamina, but because they are stacked upon each other and at the wing substrate, a faint bluish to white color results. Lastly, green wing patches (H. doris) have cover scales with blue-reflecting thin films and short-wavelength absorbing 3-OH-kynurenine, together causing a green color. The pigmentary and structural traits are discussed in relation to their phylogenetic distribution and the evolution of vision in this highly interesting clade of butterflies.

  3. Emolabeling increases healthy food choices among grade school children in a structured grocery aisle setting.

    Privitera, Gregory J; Phillips, Taylor E; Zuraikat, Faris M; Paque, Robert

    2015-09-01

    Health literacy, the ability to acquire health-related knowledge and make appropriate health-related decisions, is regarded as a key barrier to meaningfully convey health information to children and can impact food choice. Emolabeling is an image-based labeling strategy aimed at addressing this problem by conveying health information using emotional correlates of health using emoticons (happy = healthy; sad = not healthy). To test the utility of such a method to promote healthy food choices among children, 64 children (59% girls, foods in each of 2 aisles structured to mimic a grocery aisle - there were 12 identical foods placed in the same location in each aisle with half being low calorie and half high calorie snacks. Foods were emolabeled in one aisle; no emolabels were used in the other aisle; the order that children were brought in each aisle was counterbalanced. Results showed that adding emolabels increased the number (M ± SD) of healthy foods chosen (3.6 ± 0.7 with vs. 2.3 ± 1.1 without emolabels present [95% CI 1.0, 1.5], R(2) = .67) and reduced the total calories (M ± SD) of foods chosen (193.5 ± 88.5 Cal with vs. 374.3 ± 152.6 Cal without emolabels present [95% CI -212.6, -149.0], R(2) = .70). Hence, adding emolabels was associated with healthier food choices among children, thereby demonstrating one possible strategy to effectively overcome health literacy barriers at these ages.

  6. Knowledge and theme discovery across very large biological data sets using distributed queries: a prototype combining unstructured and structured data.

    Uma S Mudunuri

    Full Text Available As the discipline of biomedical science continues to apply new technologies capable of producing unprecedented volumes of noisy and complex biological data, it has become evident that available methods for deriving meaningful information from such data are simply not keeping pace. In order to achieve useful results, researchers require methods that consolidate, store and query combinations of structured and unstructured data sets efficiently and effectively. As we move towards personalized medicine, the need to combine unstructured data, such as medical literature, with large amounts of highly structured and high-throughput data such as human variation or expression data from very large cohorts, is especially urgent. For our study, we investigated a likely biomedical query using the Hadoop framework. We ran queries using native MapReduce tools we developed as well as other open source and proprietary tools. Our results suggest that the available technologies within the Big Data domain can reduce the time and effort needed to utilize and apply distributed queries over large datasets in practical clinical applications in the life sciences domain. The methodologies and technologies discussed in this paper set the stage for a more detailed evaluation that investigates how various data structures and data models are best mapped to the proper computational framework.

  7. Frequency formats, probability formats, or problem structure? A test of the nested-sets hypothesis in an extensional reasoning task

    William P. Neace

    2008-02-01

    Full Text Available Five experiments addressed a controversy in the probability judgment literature that centers on the efficacy of framing probabilities as frequencies. The natural frequency view predicts that frequency formats attenuate errors, while the nested-sets view predicts that highlighting the set-subset structure of the problem reduces error, regardless of problem format. This study tested these predictions using a conjunction task. Previous studies reporting that frequency formats reduced conjunction errors confounded reference class with problem format. After controlling this confound, the present study's findings show that conjunction errors can be reduced using either a probability or a frequency format, that frequency effects depend upon the presence of a reference class, and that frequency formats do not promote better statistical reasoning than probability formats.

    2011-09-01

    The purpose of present study was to create and test a model that illustrates variables that influence the development of addiction susceptibility and determine how different styles of parenting may indirectly influence the addiction susceptibility of children through the mediators of attachment style and self-regulation. Using random cluster sampling, 508 adolescent high school boys and girls aged 14-19 years were enrolled. Data were analyzed using structural equations modeling (path analysis). The results showed that authoritative and permissive parenting styles were associated with secure attachment whereas authoritarian and neglectful parenting styles were associated with insecure attachment. Insecure attachment was associated with a low level of self-regulation whereas secure attachment was associated with a high level of self-regulation. We found that a low level of self-regulation increased the adolescent's addiction susceptibility whereas a high level of self-regulation decreased their addiction susceptibility. The findings of present study suggest the authoritative and permissive parenting styles as the most efficient styles and authoritarian and neglectful parenting styles as the most inefficient styles in terms of addiction susceptibility. Accordingly, efficient parenting style training to parents should be the main goal of drug demand reduction program.

  11. A database paradigm for the management of DICOM-RT structure sets using a geographic information system

    Shao, Weber; Kupelian, Patrick A; Wang, Jason; Low, Daniel A; Ruan, Dan

    2014-01-01

    We devise a paradigm for representing the DICOM-RT structure sets in a database management system, in such way that secondary calculations of geometric information can be performed quickly from the existing contour definitions. The implementation of this paradigm is achieved using the PostgreSQL database system and the PostGIS extension, a geographic information system commonly used for encoding geographical map data. The proposed paradigm eliminates the overhead of retrieving large data records from the database, as well as the need to implement various numerical and data parsing routines, when additional information related to the geometry of the anatomy is desired.

  13. Social influence and adolescent health-related physical activity in structured and unstructured settings: role of channel and type.

    Spink, Kevin S; Wilson, Kathleen S; Ulvick, Jocelyn

    2012-08-01

    Social influence channels (e.g., parents) and types (e.g., compliance) have each been related to physical activity independently, but little is known about how these two categories of influence may operate in combination. This study examined the relationships between various combinations of social influence and physical activity among youth across structured and unstructured settings. Adolescents (N=304), classified as high or low active, reported the social influence combinations they received for being active. Participants identified three channels and three types of influence associated with being active. For structured activity, compliance with peers and significant others predicted membership in the high active group (values of psocial influence, when examining health-related physical activity.

  14. Nucleon internal structure: a new set of quark, gluon momentum, angular momentum operators and parton distribution functions

    Wang Fan; Sun Weimin; Chen Xiangsong; Lu Xiaofu; Goldman, T.

    2009-01-01

    It is unavoidable to deal with the quark and gluon momentum and angular momentum contributions to the nucleon momentum and spin in the study of nucleon internal structure. However we never have the quark and gluon momentum, orbital angular momentum and gluon spin operators which satisfy both the gauge invariance and the canonical momentum and angular momentum commutation relation. The conflicts between the gauge invariance and canonical quantization requirement of these operators are discussed. A new set of quark and gluon momentum, orbital angular momentum and spin operators, which satisfy both the gauge invariance and canonical momentum and angular momentum commutation relation, are proposed. The key point to achieve such a proper decomposition is to separate the gauge field into the pure gauge and the gauge covariant parts. The same conflicts also exist in QED and quantum mechanics and have been solved in the same manner. The impacts of this new decomposition to the nucleon internal structure are discussed. (authors)

  15. Driving styles and their associations with personality and motivation.

    Taubman-Ben-Ari, Orit; Yehiel, Dalia

    2012-03-01

    The associations between driving styles and the Big-Five personality factors and perceived costs and benefits of driving were examined in order to obtain a more comprehensive understanding of driving styles. Questionnaires tapping driving style, personality traits, motivations for driving, and background variables were completed by 320 drivers (150 men and 170 women). The results show that each driving style is associated with a unique set of sociodemographic, personality, and motivational factors. The reckless and angry styles were both endorsed more by men than women, by younger drivers, and by those displaying higher levels of Extroversion and thrill seeking, and lower levels of Agreeableness and Conscientiousness. However, whereas the reckless style was also predicted by the perceived costs of driving-related distress, as well as higher perceived risk to life among those with higher education, the angry style was also predicted by perceptions of both control and annoyance among more educated drivers. The anxious style was endorsed more by women, and by drivers lower on Conscientiousness and higher on Neuroticism. Individuals reporting this style regard driving as a cause of distress and annoyance, and, depending on their level of education, perceive it as entailing more risk to life and as a potential damage to their self-image (higher education), or as providing more opportunities for impression management (lower education). The careful driving style was endorsed more by women, and associated with higher Agreeableness, Conscientiousness, and Openness, along with higher pleasure (especially among younger drivers), but lower thrill seeking and worries about damage to self-esteem. The discussion focuses on the importance of looking at driving styles and their predictors holistically in order to design practical interventions suited to different profiles of drivers.

  18. Rondocubism versus National Style

    Hnídková, Vendula

    2010-11-01

    Full Text Available There is a range of various terms used to refer to architectural production from the period after the First World War, among the most common being 'Rondocubism' and the 'National Style'. The terminological ambiguity clearly points to the problem with the very character of the style of expression that lies behind these diverse labels. In the 1920s, figures of the interwar avant-garde were already sharply critical of the post-war decorative style, the leading figures of which were the architects Pavel Janák and Josef Gočár. While this negative stigma was later overcome, following several thematic studies, it is still possible to look for other inspiring sources outside aesthetic categories that were directed at clarifying this theme. Extensive social projects had architects employed in all sorts of artistic activities, and therefore a possible answer to what the essence of the style was is offered by the wider political and cultural context. After the foundation of the Czechoslovak Republic, the former protagonists of architectural Cubism and their colleagues from the Czechoslovak Workshop Association, Artěl and the School of Decorative Arts attained such social standing that they could effectively influence local artistic development. Through the individual conception applied to official commissions they created a visual identity of the new state system. As is apparent from their theoretical writings, they found their sources of information for ornamental decoration of buildings and craft artefacts by bonding with local tradition. This did not of course mean directly borrowing from folk-art prototypes. Advanced forms of national art were intended to help establish Czechoslovakia in the international scene and were also a conscious attempt through a more folkish form of expression to appeal to the wider strata of the population.

  19. Framing Gangnam Style

    Hyunsun Catherine Yoon

    2017-08-01

    Full Text Available This paper examines the way in which news about Gangnam Style was framed in the Korean press. First released on 15th July 2012, it became the first video to pass two billion views on YouTube. 400 news articles between July 2012 and March 2013 from two South Korean newspapers - Chosun Ilbo and Hankyoreh were analyzed using the frame analysis method in five categories: industry/economy, globalization, cultural interest, criticism, and competition. The right-left opinion cleavage is important because news frames interact with official discourses, audience frames and prior knowledge which consequently mediate effects on public opinion, policy debates, social movement and individual interpretations. Whilst the existing literature on Gangnam Style took rather holistic approach, this study aimed to fill the lacuna, considering this phenomenon as a dynamic process, by segmenting different stages - recognition, spread, peak and continuation. Both newspapers acknowledged Gangnam Style was an epochal event but their perspectives and news frames were different; globalization frame was most frequently used in Chosun Ilbo whereas cultural interest frame was most often used in Hankyoreh. Although more critical approaches were found in Hankyoreh, reflecting the right-left opinion cleavage, both papers lacked in critical appraisal and analysis of Gangnam Style’s reception in a broader context of the new Korean Wave.

  20. Structure, diversity and environmental role of foraminiferal assemblages from reefal settings of Moorea (Society Islands, French Polynesia)

    Fajemila, Olugbenga; Langer, Martin R.

    2015-04-01

    Reefal and shallow lagoonal environments around the island Moorea (Society Islands, French Polynesia) offer a spectacular variety of microhabitats providing a multitude niches and ideal settings for rich assemblages of tropical benthic foraminifera. The Society Islands are located near the hotspot of tropical marine diversity and represent a transitional location between the high diversity assemblages of the coral triangle and the low diversity biotas of the eastern Pacific. This area constitutes an important biogeographic link and stepping stone between the eastern and western biotas of the tropical Pacific Ocean. We have analyzed the structure, diversity and composition of benthic foraminiferal assemblages from around Moorea to document the composition, species richness and environmental role of larger and smaller benthic foraminifera from within the lagoonal system, the mangrove habitats and fore-reef sites. Foraminifera are prominent producers of calcium carbonate and contribute significantly to structures in reefal settings of the tropical Pacific. We evaluate the potential of larger symbiont-bearing foraminifera as environmental engineers and apply the FORAM-Index as proxy to assess the conditions around Moorea Island. We also evaluate the role of the Society Islands as stepping stone between biogeographic regions of the Pacific Ocean.

  1. Assessing the reliability of the borderline regression method as a standard setting procedure for objective structured clinical examination

    Sara Mortaz Hejri

    2013-01-01

    Full Text Available Background: One of the methods used for standard setting is the borderline regression method (BRM. This study aims to assess the reliability of BRM when the pass-fail standard in an objective structured clinical examination (OSCE was calculated by averaging the BRM standards obtained for each station separately. Materials and Methods: In nine stations of the OSCE with direct observation the examiners gave each student a checklist score and a global score. Using a linear regression model for each station, we calculated the checklist score cut-off on the regression equation for the global scale cut-off set at 2. The OSCE pass-fail standard was defined as the average of all station′s standard. To determine the reliability, the root mean square error (RMSE was calculated. The R2 coefficient and the inter-grade discrimination were calculated to assess the quality of OSCE. Results: The mean total test score was 60.78. The OSCE pass-fail standard and its RMSE were 47.37 and 0.55, respectively. The R2 coefficients ranged from 0.44 to 0.79. The inter-grade discrimination score varied greatly among stations. Conclusion: The RMSE of the standard was very small indicating that BRM is a reliable method of setting standard for OSCE, which has the advantage of providing data for quality assurance.

    Full Text Available Cynthia Cassoni,1 Regina HL Caldana21Graduate School in Psychology, 2Department of Psychology and Education, Faculdade de Filosofia, Ciências e Letras de Ribeirão Preto, Universidade de São Paulo, Ribeirão Preto, SP BrazilAbstract: There are several studies on the best way to raise a child, ie, what would be the consequences of our actions for our children. We tend to think of how to educate children in a traditional family, but society has undergone many changes and, hence, family structures have undergone changes too. Today, we find a large number of stepfamilies facing the same issues concerning how to educate a child. Stepfamily configuration often entails more than just the addition of a new parent figure. The objective of this study was to shed some light on how these stepfamilies deal with issues of parenting style and practices. We reviewed the Brazilian and international literature concerning parenting styles and practices in stepfamilies. The papers identified were organized and submitted to analysis. We identified very few papers addressing parenting styles and practices, pointing to an important but unaddressed social change as reflected in new family structures. There is a need for longitudinal studies aimed at understanding not only a particular moment in time, but also moments within a context, ie, an analysis with a holistic approach without preconceived ideas.Keywords: parenting styles, parenting practices, stepfamilies

  3. Relationship Between Leadership Styles and Organizational Creativity

    Katarzyna Bratnicka

    2015-03-01

    Full Text Available Purpose: Empirical research on entrepreneurship in organizations has brought disparate and often contradictory evidence related to the impact of leadership on creativity in organizations. The purpose of this paper is to explore and discuss the impact of different leadership styles on creativity, with the view to formulating an integrated conceptual model that links creative novelty and creative practicality with leadership. Methodology: The author applied the methodology of meta-theoretical review. In accordance with the principles of theoretical bricolage, a new conceptual model was built on the basis of the multidimensional creativity theory and the leadership theory. In her analysis, the author took into account leadership styles that have already been subject to research; each of them was mapped in the two-dimensional space of organizational creativity. Findings: In order to fully understand the reasons for differences in organizational creativity, the drivers of divergences in the space of creative novelty and creative practicality need to be clarified. Greater knowledge about the impact of leadership styles on the structure and configuration of organizational creativity is necessary. In this paper, the author provides a theoretical framework that illustrates manners in which leadership influences organizational creativity. The model clarifies the role that leadership plays in shaping a unique configuration of organizational creativity, and consequently in ensuring the necessary internal adaptation of an organization. Originality: The value of this research lies in the situational interpretation of various leadership styles in the context of their impact on organizational creativity. The analysis goes beyond the conventional discussion about leadership and creativity, focused on establishing whether a given leadership style proves beneficial or not for organizational creativity. The paper identifies particular effects that several key

  4. Analytic cognitive style predicts religious and paranormal belief.

    2012-06-01

    An analytic cognitive style denotes a propensity to set aside highly salient intuitions when engaging in problem solving. We assess the hypothesis that an analytic cognitive style is associated with a history of questioning, altering, and rejecting (i.e., unbelieving) supernatural claims, both religious and paranormal. In two studies, we examined associations of God beliefs, religious engagement (attendance at religious services, praying, etc.), conventional religious beliefs (heaven, miracles, etc.) and paranormal beliefs (extrasensory perception, levitation, etc.) with performance measures of cognitive ability and analytic cognitive style. An analytic cognitive style negatively predicted both religious and paranormal beliefs when controlling for cognitive ability as well as religious engagement, sex, age, political ideology, and education. Participants more willing to engage in analytic reasoning were less likely to endorse supernatural beliefs. Further, an association between analytic cognitive style and religious engagement was mediated by religious beliefs, suggesting that an analytic cognitive style negatively affects religious engagement via lower acceptance of conventional religious beliefs. Results for types of God belief indicate that the association between an analytic cognitive style and God beliefs is more nuanced than mere acceptance and rejection, but also includes adopting less conventional God beliefs, such as Pantheism or Deism. Our data are consistent with the idea that two people who share the same cognitive ability, education, political ideology, sex, age and level of religious engagement can acquire very different sets of beliefs about the world if they differ in their propensity to think analytically.

    2013-10-01

    The use of procedural sedation outside the operating theatre has increased in hospital settings and has gained popularity among non-anesthesiologists. Sedative agents used for procedural pain, although effective, also pose significant risks to the patient if used incorrectly. There is currently no universally accepted program of education for practitioners using or introducing procedural sedation into their practice. There is emerging literature identifying structured procedural sedation programs (PSPs) as a method of ensuring a standardized level of competency among staff and reducing risks to the patient. We hypothesize that programs of education for healthcare professionals using procedural sedation outside the operating theatre are beneficial in improving patient care, safety, practitioner competence and reducing adverse event rates. Electronic databases will be systematically searched for studies (randomized and non-randomized) examining the effectiveness of structured PSPs from 1966 to present. Database searches will be supplemented by contact with experts, reference and citation checking, and a grey literature search. No language restriction will be imposed. Screening of titles and abstracts, and data extraction will be performed by two independent reviewers. All disagreements will be resolved by discussion with an independent third party. Data analysis will be completed adhering to procedures outlined in the Cochrane Handbook of Systematic Reviews of Interventions. If the data allows, a meta-analysis will be performed. This review will cohere evidence on the effectiveness of structured PSPs on sedation events and patient outcomes within the hospital and other acute care settings. In addition, it will examine key components identified within a PSP associated with patient safety and improved patient outcomes. PROSPERO registration number: CRD42013003851.

  7. Transforming Leadership Styles and Knowledge Sharing in a Multicultural Context

    Rasa Paulienė

    2012-06-01

    Full Text Available Despite limitations on comprehensive studies, scholars accept that transformational and transactional leadership theories will have a universal application because these models have capacity for being adapted to different cultural settings. However, more exploration is required in order to develop a strong and consistent picture of the generalizability of culturally-linked leadership styles differently perceived, evaluated or enacted in diverse cultures because the meaning and importance given to the concept of leadership vary across cultures. By comparing and contrasting the number of cultural frameworks of leadership styles and drawing conclusions as to the relationship between leadership styles and culture, more holistic understanding can be attained.

  8. Towards a concept of food-related life style

    Grunert, Klaus G.

    Life style has become popular in explaining food choice. In this paper the way life style studies are usually conducted is criticized based on a) that the methods lack a theoretical foundation, b) that the statistical methods are questionable, and c)that the explanatory power with regard to food...... choice remains to be demonstrated. A cognitive deductive approach is presented as a theoretically more well-founded alternative. It defines life style as the system of cognitive categories, scripts, and their associations, which relate a set of products to a set of values. A concept of food-related life...... style should hence contain elements like shopping scripts, meal preparation scripts, desired higher-order food attributes, food usage situations, and desired consequences of food products....

    Full Text Available Background and purpose: Learning style is the processing of information and comprehension. If teachers present contents in a style that matches a student’s preferred learning style, academic performance and success will improve. If content retention improves it will result in an increase in thetest scores. It is also important to determine if students, as a group, fit into a particular style or a particular cycle as they move through an educational program.Methods: The study is a descriptive analytical research. Nursing Students at Isfahan Medical Sciences University completed a questionnaire  formulated to assess learning styles. Analysis of variance was used to investigate the possible relationship between learning cycle and student’s grades in the curriculum (i.e. freshman, sophomore, junior, or senior. Cross tabulation was used to test for a relationship between learning style and student academic year of study in the curriculum.Results: 294 students received the Kolb LSI questionnaire. The data demonstrated that juniors preferred a converger learning style and the senior students were in the abstract conceptualization cycle of learning. There were no relationships demonstrated between other groups in the study.Conclusion: The junior and senior students appear to prefer the stage of learning involving thinking and problem analysis.

  10. OTTER, Resolution Style Theorem Prover

    McCune, W.W.

    2001-01-01

    1 - Description of program or function: OTTER (Other Techniques for Theorem-proving and Effective Research) is a resolution-style theorem-proving program for first-order logic with equality. OTTER includes the inference rules binary resolution, hyper-resolution, UR-resolution, and binary para-modulation. These inference rules take as small set of clauses and infer a clause. If the inferred clause is new and useful, it is stored and may become available for subsequent inferences. Other capabilities are conversion from first-order formulas to clauses, forward and back subsumption, factoring, weighting, answer literals, term ordering, forward and back demodulation, and evaluable functions and predicates. 2 - Method of solution: For its inference process OTTER uses the given-clause algorithm, which can be viewed as a simple implementation of the set of support strategy. OTTER maintains three lists of clauses: axioms, sos (set of support), and demodulators. OTTER is not automatic. Even after the user has encoded a problem into first-order logic or into clauses, the user must choose inference rules, set options to control the processing of inferred clauses, and decide which input formulae or clauses are to be in the initial set of support and which, if any, equalities are to be demodulators. If OTTER fails to find a proof, the user may try again different initial conditions. 3 - Restrictions on the complexity of the problem - Maxima of: 5000 characters in an input string, 64 distinct variables in a clause, 51 characters in any symbol. The maxima can be changed by finding the appropriate definition in the header.h file, increasing the limit, and recompiling OTTER. There are a few constraints on the order of commands

  11. Complex fold and thrust belt structural styles: Examples from the Greater Juha area of the Papuan Fold and Thrust Belt, Papua New Guinea

    Mahoney, Luke; Hill, Kevin; McLaren, Sandra; Hanani, Amanda

    2017-07-01

    The remote and inhospitable Papuan Fold Belt in Papua New Guinea is one of the youngest yet least well-documented fold and thrust belts on Earth. Within the frontal Greater Juha area we have carried out >100 km of geological traverses and associated analyses that have added significantly to the contemporary geological and geophysical dataset. Our structural analysis provides evidence of major inversion, detachment and triangle zone faults within the uplifted Eastern Muller Ranges. We have used the dataset to develop a quasi-3D model for the Greater Juha area, with associated cross-sections revealing that the exposed Cenozoic Darai Limestone is well-constrained with very low shortening of 12.6-21.4% yet structures are elevated up to 7 km above regional. We suggest the inversion of pre-existing rift architecture is the primary influence on the evolution of the area and that structures link to the surface via triangle zones and detachment faults within the incompetent Mesozoic passive-margin sedimentary sequence underlying competent Darai Limestone. Arc-normal oriented structures, dominantly oblique dextral, up-to-the-southeast, are pervasive across a range of scales and are here interpreted to relate at depth to weakened pre-existing basement cross-structures. It is proposed that Palaeozoic basement fabric controlled the structural framework of the basin during Early Mesozoic rifting forming regional-scale accommodation zones and related local-scale transfer structures that are now expressed as regional-scale arc-normal lineaments and local-scale arc-normal structures, respectively. Transfer structures, including complexly breached relay ramps, utilise northeast-southwest striking weaknesses associated with the basement fabric, as a mechanism for accommodating displacement along major northwest-southeast striking normal faults. These structures have subsequently been inverted to form arc-normal oriented zones of tear faulting that accommodate laterally variable

  12. The German Version of the Humor Styles Questionnaire: Psychometric Properties and Overlap With Other Styles of Humor.

    Ruch, Willibald; Heintz, Sonja

    2016-08-01

    The Humor Styles Questionnaire (HSQ; Martin et al., 2003) is one of the most frequently used questionnaires in humor research and has been adapted to several languages. The HSQ measures four humor styles (affiliative, self-enhancing, aggressive, and self-defeating), which should be adaptive or potentially maladaptive to psychosocial well-being. The present study analyzes the internal consistency, factorial validity, and factorial invariance of the HSQ on the basis of several German-speaking samples combined (total N = 1,101). Separate analyses were conducted for gender (male/female), age groups (16-24, 25-35, >36 years old), and countries (Germany/Switzerland). Internal consistencies were good for the overall sample and the demographic subgroups (.80-.89), with lower values obtained for the aggressive scale (.66-.73). Principal components and confirmatory factor analyses mostly supported the four-factor structure of the HSQ. Weak factorial invariance was found across gender and age groups, while strong factorial invariance was supported across countries. Two subsamples also provided self-ratings on ten styles of humorous conduct (n = 344) and of eight comic styles (n = 285). The four HSQ scales showed small to large correlations to the styles of humorous conduct (-.54 to .65) and small to medium correlations to the comic styles (-.27 to .42). The HSQ shared on average 27.5-35.0% of the variance with the styles of humorous conduct and 13.0-15.0% of the variance with the comic styles. Thus-despite similar labels-these styles of humorous conduct and comic styles differed from the HSQ humor styles.

In two studies, we examined associations of God beliefs, religious engagement (attendance at religious services, praying, etc.), conventional religious beliefs (heaven, miracle...

  14. Structural setting of the Metán Basin (NW Argentina): new insights from 2D seismic profiles

    Conti, Alessia; Maffucci, Roberta; Bigi, Sabina; Corrado, Sveva; Giordano, Guido; Viramonte, José G.

    2017-04-01

    The Metán Basin is located in the sub-Andean foreland, in the southernmost portion of the Santa Barbara system structural province (NW Argentina). The upper crust in this region shows a strong segmentation due to inherited stratigraphic and structural discontinuities, related to a Palaeozoic orogenic event and to a Cretaceous to Paleogene rifting event (Kley et al., 1999; Iaffa et al., 2011). This study seeks to unravel the deep structural setting of the basin, in order to better understand the tectonic evolution of the area. Different seismic sections are analysed, located in the Metán basin and acquired by YPF (Yacimientos Petrolíferos Fiscales, former national oil company of Argentina) in different surveys during the '70s - '80s. Stratigraphic control for the seismic interpretation is provided by petroleum exploratory wells drilled in the basin; they show a stratigraphic succession of syn-rift and post-rift deposits, mainly constituted by a continental succession of red beds, with minor limestone intercalations (Salta Group), overlain by a thick continental foreland basin succession (Orán Group) (Salfity et al., 1981). From a structural point of view, the Metán basin is characterized by a variety of structural trends, with thrust faults and related folds mainly trending N-S, NE-SW and NNE-SSW. Different mechanism can be responsible for the folding of the sedimentary cover; hangingwall anticlines are represented both by high angle thrust faults produced by inversion of Cretaceous extensional faults (Maffucci et al., 2015), and by fault propagation folds formed during the Andean shortening event. The study of the interaction between the older reactivated faults and the newly generated ones could provide new insights to unravel the complex structural setting of the area. References Iaffa D.

    Full Text Available On the sample by 121 perspective young athletes was carried out the researching in the aim to establish the behavior style of coaches. The relevant information was obtained through the validated questionnaires of Chelladura and Saleha (1980. The questionnaire contains 40 questions which directly determine 5 behavior styles of coaches. All questions possess the scale by 5 levels with possible statements: (always, often, periodically, rarely and never. The true answer is only one statement on one question. It is word about five degrees 'Likert's scale'. It was carried out extensive and complex statistics processing of date, where the input qualitative categorical variables were transformed into quantitative. In the next step, transformed categorical variables were exposed in classical and neoclassical statistical methodology. On the base of exact indications which were obtained by using relevant invariant and multivariate statistical methods and tests, dominant behavior style of coaches is 'Instructive'. This behavior style of coach is the most desirable. According to this researching at the last position is behavior style which is the autocratically and it is also at the same time the least desirable. The results of Analysis of variance (ANOVA and Canonic discriminative analysis show the general statistical significant difference in the representation of the behavior styles. Instructive and Autocratic behavior style of coach mostly influences on the total (general discrimination i.e. difference. For above mentioned styles, it could be said that they are paradigm of contrasts in every way. Values of Tukey - HSD test explicitly shows that there are not statistical significant difference between Instructive Style and style Awarded - Feedback as well as between Democratically and style of Social Support. The other combinations i.e. couples of behavior styles are statistical significantly different.

  3. Factor structure of the Essen Climate Evaluation Schema measure of social climate in a UK medium-security setting.

    Milsom, Sophia A; Freestone, Mark; Duller, Rachel; Bouman, Marisa; Taylor, Celia

    2014-04-01

    Social climate has an influence on a number of treatment-related factors, including service users' behaviour, staff morale and treatment outcomes. Reliable assessment of social climate is, therefore, beneficial within forensic mental health settings. The Essen Climate Evaluation Schema (EssenCES) has been validated in forensic mental health services in the UK and Germany. Preliminary normative data have been produced for UK high-security national health services and German medium-security and high-security services. We aim to validate the use of the EssenCES scale (English version) and provide preliminary normative data in UK medium-security hospital settings. The EssenCES scale was completed in a medium-security mental health service as part of a service-wide audit. A total of 89 patients and 112 staff completed the EssenCES. The three-factor structure of the EssenCES and its internal construct validity were maintained within the sample. Scores from this medium-security hospital sample were significantly higher than those from earlier high-security hospital data, with three exceptions--'patient cohesion' according to the patients and 'therapeutic hold' according to staff and patients. Our data support the use of the EssenCES scale as a valid measure for assessing social climate within medium-security hospital settings. Significant differences between the means of high-security and medium-security service samples imply that degree of security is a relevant factor affecting the ward climate and that in monitoring quality of secure services, it is likely to be important to apply different scores to reflect standards.

  4. Set anode potentials affect the electron fluxes and microbial community structure in propionate-fed microbial electrolysis cells

    Rao, Hari Ananda

    2016-12-09

    Anode potential has been shown to be a critical factor in the rate of acetate removal in microbial electrolysis cells (MECs), but studies with fermentable substrates and set potentials are lacking. Here, we examined the impact of three different set anode potentials (SAPs; −0.25, 0, and 0.25 V vs. standard hydrogen electrode) on the electrochemical performance, electron flux to various sinks, and anodic microbial community structure in two-chambered MECs fed with propionate. Electrical current (49–71%) and CH4 (22.9–41%) were the largest electron sinks regardless of the potentials tested. Among the three SAPs tested, 0 V showed the highest electron flux to electrical current (71 ± 5%) and the lowest flux to CH4 (22.9 ± 1.2%). In contrast, the SAP of −0.25 V had the lowest electron flux to current (49 ± 6%) and the highest flux to CH4 (41.1 ± 2%). The most dominant genera detected on the anode of all three SAPs based on 16S rRNA gene sequencing were Geobacter, Smithella and Syntrophobacter, but their relative abundance varied among the tested SAPs. Microbial community analysis implies that complete degradation of propionate in all the tested SAPs was facilitated by syntrophic interactions between fermenters and Geobacter at the anode and ferementers and hydrogenotrophic methanogens in suspension.

  5. The influence of structural and institutional change on teaching and culture in clinical settings: an exploratory study.

    Goldie, J; Dowie, A; Goldie, Anne; Cotton, Phil; Morrison, Jill

    2015-02-01

    Learning in clinical settings is a function of activity, context and culture. Glasgow University's Medical School has undergone significant curricular change in recent years. This has coincided with change to National Health Service consultants' contracts, the introduction of the European Working Time Directive and the Modernising Medical Careers training initiative. We wished to explore teachers' and students' perspectives on the effects of change on our clinical teachers' capacity for teaching and on medical culture. A qualitative approach using individual interviews with educational supervisors and focus groups with senior clinical students was used. Data were analysed using a "framework" technique. Curricular change has led to shorter clinical attachments in the senior clinical rotation, which combined with more centralised teaching have had adverse effects on both formal and informal teaching during attachments. Consultants' NHS contract changes the implementation of the European Working Time Directive and changes to postgraduate training have adversely affected consultants' teaching capacity, which has had a detrimental effect on their relationships with students. Medical culture has also changed as a result of these and other societal influences. The apprenticeship model was still felt to be relevant in clinical settings. This has to be balanced against the need for systematic teaching. Structural and institutional change affects learning. Faculty needs to be aware of the socio-historical context of their institutions.

  6. Relation between birth order and interpersonal styles

    Mauro de Oliveira Magalhães

    2009-10-01

    Full Text Available Interpersonal style is an aspect of personality related to the particular way individuals participate and gain influence in social contexts. It has its origin in childhood’s first social interactions within the family group. It is suggested that the individual position in the family structure, namely birth order, is an important variable in this process. The present study investigated combined effects of sex and birth order on interpersonal style. A sample of 435 college students (196 men and 239 women with ranging in age from 18 to 40 years (M = 23,3 answered the BASIS-A (Basic Adlerian Scales of Interpersonal Styles and a brief demographic questionnaire. Interactions between sex and birth order were found. Lastborn women showed greater tendency to search for success and social approval than firstborn women and lastborn men. Among men, lastborn revealed less need for social approval compared to firstborn and only children. First born men showed a higher need to attend social conventions and obtain success. The interaction between sex and birth order was relevant for the understanding of personality development in the context of family relations.   Keywords: birth order; interpersonal styles; personality.

  7. Parenting Style as a Moderator for Students' Academic Achievement

    Ishak, Zahari; Low, Suet Fin; Lau, Poh Li

    2012-08-01

    Parenting styles have always been a crucial factor in influencing all aspects of a person's development. The purpose of this study is to test the structural equation model of academic achievement among the students using parenting styles as a moderator. The sample comprised 493 students from eight schools. Parenting styles are determined using the Parental Authority Questionnaire (Buri in J Pers Assess 57:110-119, 1991). Academic achievement is measured based on the students' performance in the Lower Secondary Assessment. Data were analyzed using structural equation modelling. Results demonstrated that model of authoritative and model of authoritarian fit the data of this study well. Both authoritative and authoritarian parenting styles are the most common practice of the parents. Parenting styles have been found to be a moderator of this study. The results indicated that parenting styles moderated the effect of academic self-concept on academic achievement. The impact of academic self-concept on academic achievement is found to be greater for the authoritative than the authoritarian parenting style.

  8. Quantitative structure-activity relationship study of antioxidative peptide by using different sets of amino acids descriptors

    Li, Yao-Wang; Li, Bo; He, Jiguo; Qian, Ping

    2011-07-01

    A database consisting of 214 tripeptides which contain either His or Tyr residue was applied to study quantitative structure-activity relationships (QSAR) of antioxidative tripeptides. Partial Least-Squares Regression analysis (PLSR) was conducted using parameters individually of each amino acid descriptor, including Divided Physico-chemical Property Scores (DPPS), Hydrophobic, Electronic, Steric, and Hydrogen (HESH), Vectors of Hydrophobic, Steric, and Electronic properties (VHSE), Molecular Surface-Weighted Holistic Invariant Molecular (MS-WHIM), isotropic surface area-electronic charge index (ISA-ECI) and Z-scale, to describe antioxidative tripeptides as X-variables and antioxidant activities measured with ferric thiocyanate methods were as Y-variable. After elimination of outliers by Hotelling's T 2 method and residual analysis, six significant models were obtained describing the entire data set. According to cumulative squared multiple correlation coefficients ( R2), cumulative cross-validation coefficients ( Q2) and relative standard deviation for calibration set (RSD c), the qualities of models using DPPS, HESH, ISA-ECI, and VHSE descriptors are better ( R2 > 0.6, Q2 > 0.5, RSD c 0.44). Furthermore, the predictive ability of models using DPPS descriptor is best among the six descriptors systems (cumulative multiple correlation coefficient for predict set ( Rext2) > 0.7). It was concluded that the DPPS is better to describe the amino acid of antioxidative tripeptides. The results of DPPS descriptor reveal that the importance of the center amino acid and the N-terminal amino acid are far more than the importance of the C-terminal amino acid for antioxidative tripeptides. The hydrophobic (positively to activity) and electronic (negatively to activity) properties of the N-terminal amino acid are suggested to play the most important significance to activity, followed by the hydrogen bond (positively to activity) of the center amino acid. The N-terminal amino acid

  9. Ward leadership styles.

    Bowman, G

    1989-01-01

    The purpose of this study was to devise a leadership style scale based in the authoritarian/democratic concept of leadership and to test it with a group of nurses. The working hypothesis was that nurses, working by primary nursing methods, would have a more democratic attitude to leadership than those nurses working in a traditional task allocation system. Recent papers such as that of Henry & Tuxill (1) plead for the caring professions to take on board the concept of the 'person'. Not only is the traditional model of nursing care seen as bad for the patient; it is seen also as harmful to the nurses. Fretwell (2) describes the task system as essentially an industrial model rather than a professional one which tends to satisfy the needs of the doctor rather than the patient or nurse. Kinston (3) describes nursing decision-making and work as Level I work (tradesmen). Current models of care that individualize the nurse's response to work and decision-making become Level II type (professional). Primary nursing fulfils the need for professionalizing nursing and meeting the need for more independence as well as respecting the patient as a 'person' with the organisation there to facilitate interaction between qualified nurse and patient. Changes in attitude and relationships are essential if work is to change from task to person-centred. Styles of leadership in nurses need to alter as our orientation to care issues change (4).(ABSTRACT TRUNCATED AT 250 WORDS)

  10. Teaching Styles, Learning Styles and the ESP Classroom

    2018-01-01

    Full Text Available Learner diversity that exists in the classroom plays a role in influencing the teaching and learning process in the classroom. It should be acknowledged in order for the teaching and learning process to be a meaningful and effective process. Thus, this study examined the learning styles preference of engineering students and the teaching styles preferences of their Technical Communication lecturers. The study also looked at whether the students’ learning styles preferences were influenced by their field of study, gender and ethnic backgrounds. Felder and Solomon’s Index of Learning Styles was administered to 588 engineering students while Grasha and Riechmann-Hruska’s Teaching Style Survey was administered to 10 Technical Communication lecturers. The findings revealed that the students have a marked preference for the visual learning style but balanced preferences for the other learning styles dimensions. The students’ field of study, gender and ethnic backgrounds did not seem to influence the students’ learning styles preferences. As for their Technical Communication lecturers, they seem to favour the student-centered teaching approach. All the data support the notion of adopting a balanced teaching approach in the Technical Communication classroom.

  12. The development and validation of the On-the-job Learning Styles Questionnaire for the Nursing Profession.

    Berings, Marjolein G M C; Poell, Rob F; Simons, P Robert-Jan; van Veldhoven, Marc J P M

    2007-06-01

    This paper is a report of a study to develop and test the psychometric properties of the On-the-job Learning Style Questionnaire for the Nursing Profession. Although numerous questionnaires measuring learning styles have been developed, none are suitable for working environments. Existing instruments do not meet the requirements for use in workplace settings and tend to ignore the influence of different learning situations. The questionnaire was constructed using a situation-response design, measuring learning activities in different on-the-job learning situations. Content validity was ensured by basing the questionnaire on interview studies. The questionnaire was distributed to 912 Registered Nurses working in different departments of 13 general hospitals in the Netherlands at the end of 2005. The response rate was 41% (372 questionnaires). The internal factor structure of the questionnaire was partly based on the learning activities in which nurses participate and partly on the learning situation in which they are performed. The internal consistency was good. The situation-response design of the questionnaire demonstrated its added value. Construct validity was estimated using intercorrelations between the scales, and criterion validity was estimated based on the relationships of the scales with perceived professional competence. The On-the-job Learning Styles Questionnaire for the Nursing Profession is well suited to describing nurses' learning styles in on-the-job settings and has satisfactory psychometric properties.

    Full Text Available Many studies have focused on the attachment styles and their impact on human functioning and relationships (Bretherton, 1992. Some attachment styles have been associated with pathological way of human overall functioning, and it has already been observed that insecure attachment style in childhood may be associated with personality dysfunction (Brennan & Shaver, 1998. The purpose of this study is to investigate how people diagnosed with borderline personality disorder (BPD describe their attachment style to the primary caregivers from their memories from childhood. This study was conducted in Germany in an inpatient psychiatric clinic. Fifteen participants represented a convenience sample, of patients already diagnosed with BPD. For this study Adult Attachment Interview (AAI was used. The AAI is a semi-structured interview focusing on the early attachment experiences and their effects based on Attachment Theory.The results indicated that people diagnosed with BPD showed both preoccupied and dismissing child-parent attachment style,however it was the dismissing attachment style that dominated in our sample. The findings supported the hypothesis that participants who showed dismissing attachment style also used positive adjectives to describe the relationship  with their primary caregiver, and those with the preoccupied attachment style used negative adjectives to describe the relationship  with their primary caregiver. Even though, study was conducted with small number of participants, the study did provide evidence that there is a relationship between BPD and attachment styles in childhood. Threfore, the study offered contribution to the already existing knowledge and research findings regarding the influence of attachment style on BPD development.

  16. Style grammars for interactive visualization of architecture.

    Aliaga, Daniel G; Rosen, Paul A; Bekins, Daniel R

    2007-01-01

    Interactive visualization of architecture provides a way to quickly visualize existing or novel buildings and structures. Such applications require both fast rendering and an effortless input regimen for creating and changing architecture using high-level editing operations that automatically fill in the necessary details. Procedural modeling and synthesis is a powerful paradigm that yields high data amplification and can be coupled with fast-rendering techniques to quickly generate plausible details of a scene without much or any user interaction. Previously, forward generating procedural methods have been proposed where a procedure is explicitly created to generate particular content. In this paper, we present our work in inverse procedural modeling of buildings and describe how to use an extracted repertoire of building grammars to facilitate the visualization and quick modification of architectural structures and buildings. We demonstrate an interactive application where the user draws simple building blocks and, using our system, can automatically complete the building "in the style of" other buildings using view-dependent texture mapping or nonphotorealistic rendering techniques. Our system supports an arbitrary number of building grammars created from user subdivided building models and captured photographs. Using only edit, copy, and paste metaphors, the entire building styles can be altered and transferred from one building to another in a few operations, enhancing the ability to modify an existing architectural structure or to visualize a novel building in the style of the others.

    2008-11-01

    The present study aims to determine the relationship among factors that make up the parenting styles according to the PCRI (Parent-Child Relationship Inventory) and hyperactivity reported by parents through the BASC (Behaviour Assessment System for Children). We selected a sample of 32 children between 3 and 14 years old (23 male and 9 female) with risk scores in hyperactivity and another similar group with low scores in hyperactivity. After administering both instruments to the parents, we carried out a binomial logistic regression analysis which resulted in a prediction model for 84.4% of the sample, made up of the PCRI factors: fathers' involvement, communication and role orientation, mothers' parental support, and both parents' limit-setting and autonomy. Moreover, our analysis of the variance produced significant differences in the support perceived by the fathers and mothers of both groups. Lastly, the utility of results to propose intervention strategies within the family based on an authoritative style is discussed.

  20. Relationship of Cognitive Style and Job Level: First Demonstration of Cultural Differences.

    Kageyama, Tetsuya; Sugiura, Motoaki

    2017-01-01

    Higher-level managers are said to have a more intuitive cognitive style. To verify this hypothesis, we must consider three factors that have often been left out of account. Previous studies, related to managerial cognitive style and job level, used a unidimensional model of cognitive style, did not consider age, and have mainly been conducted in the UK. Our study replicated previous studies on a population of 1,533 Japanese fulltime workers, using a questionnaire based on a two-dimensional model of cognitive style and setting a frame by age for each job level. Our results showed that higher job levels are associated with more rational cognitive styles. There were significant main effects of the interaction of job level and job level by age in rational thinking style. There was no correlation between intuition and job level. Our findings are the first demonstration that the relationship between job level and cognitive style likely depends on culture.

  2. Assessment of semiempirical enthalpy of formation in solution as an effective energy function to discriminate native-like structures in protein decoy sets.

    Urquiza-Carvalho, Gabriel Aires; Fragoso, Wallace Duarte; Rocha, Gerd Bruno

    2016-08-05

    In this work, we tested the PM6, PM6-DH+, PM6-D3, and PM7 enthalpies of formation in aqueous solution as scoring functions across 33 decoy sets to discriminate native structures or good models in a decoy set. In each set these semiempirical quantum chemistry methods were compared according to enthalpic and geometric criteria. Enthalpically, we compared the methods according to how much lower was the enthalpy of each native, when compared with the mean enthalpy of its set. Geometrically, we compared the methods according to the fraction of native contacts (Q), which is a measure of geometric closeness between an arbitrary structure and the native. For each set and method, the Q of the best decoy was compared with the Q0 , which is the Q of the decoy closest to the native in the set. It was shown that the PM7 method is able to assign larger energy differences between the native structure and the decoys in a set, arguably because of a better description of dispersion interactions, however PM6-DH+ was slightly better than the rest at selecting geometrically good models in the absence of a native structure in the set. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  3. Geomorphic and Structural Evidence for Rolling Hinge Style Deformation in the Footwall of an Active Low Angle Normal Fault, Mai'iu Fault, Woodlark Rift, SE Papua New Guinea

    Mizera, M.; Little, T.; Norton, K. P.; Webber, S.; Ellis, S. M.; Oesterle, J.

    2016-12-01

    While shown to operate in oceanic crust, rolling hinge style deformation remains a debated process in metamorpic core complexes (MCCs) in the continents. The model predicts that unloading and isostatic uplift during slip causes a progressive back-tilting in the upper crust of a normal fault that is more steeply dipping at depth. The Mai'iu Fault in the Woodlark Rift, SE Papua New Guinea, is one of the best-exposed and fastest slipping (probably >7 mm/yr) active low-angle normal faults (LANFs) on Earth. We analysed structural field data from this fault's exhumed slip surface and footwall, together with geomorphic data interpreted from aerial photographs and GeoSAR-derived digital elevation models (gridded at 5-30 m spacing), to evaluate deformational processes affecting the rapidly exhuming, domal-shaped detachment fault. The exhumed fault surface emerges from the ground at the rangefront near sea level with a northward dip of 21°. Up-dip, it is well-preserved, smooth and corrugated, with some fault remnants extending at least 29 km in the slip direction. The surface flattens over the crest of the dome, beyond where it dips S at up to 15°. Windgaps perched on the crestal main divide of the dome, indicate both up-dip tectonic advection and progressive back-tilting of the exhuming fault surface. We infer that slip on a serial array of m-to-km scale up-to-the-north, steeply S-dipping ( 75°) antithetic-sense normal faults accommodated some of the exhumation-related, inelastic bending of the footwall. These geomorphically well expressed faults strike parallel to the main Mai'iu fault at 110.9±5°, have a mean cross-strike spacing of 1520 m, and slip with a consistent up-to-the-north sense of throw ranging from <5 m to 120 m. Apparently the Mai'iu Fault was able to continue slipping despite having to negotiate this added fault-roughness. We interpret the antithetic faulting to result from bending stresses, and to provide the first clear examples of rolling hinge-style

  10. Lay Perceptions of Healthy Eating Styles and Their Health Impacts.

    Vizireanu, Mariya; Hruschka, Daniel

    2018-04-01

    This study examined perceptions of healthy eating styles among US respondents to determine whether eating styles are defined as a distinct set of people's healthy eating beliefs and how different aspects of eating styles are perceived to affect health. In-person pile sort activities were used to identify key dimensions of healthy eating beliefs, and online surveys were used to confirm these dimensions and examine perceived health benefits of healthy eating styles. The pile-sorting activity recruited 48 US participants in the Phoenix metropolitan area via social media and snowball sampling. Online surveys recruited US participants via Amazon Mechanical Turk (survey 1, n = 70; survey 2, n = 283). The researchers used an exploratory visualizing technique (multidimensional scaling) to analyze pile sort data; Property Filling (PROFIT) analysis was used to analyze online survey 1; paired sample t test and repeated-measures ANOVA were used to analyze online survey 2. Eating styles are a distinct set of beliefs within lay models of healthful diets (P management. In addition to educating the public about choosing healthy food characteristics, health and nutrition professionals may need to address people's beliefs regarding healthy eating styles to identify gaps and misconceptions. Future research is needed to examine the relationships between such beliefs and corresponding behaviors, as well as whether these behaviors result in any health benefits.

  11. Universal Style Sheet Language Environment Modification for the Business Use

    Jiří Brázdil

    2014-01-01

    Full Text Available This paper deals with the description of USSL – Universal Style Sheet Language environment. USSL style sheet language is platform-independent and its primary focus is the declarative notation of the appearance of GUI libraries used by imperative programming languages. The implementation of the software support for wxWidgets library is made, because this library has no support for the separate declarative notation of the appearance via style sheet language. The separation of the appearance enables us to reuse and standardize the appearance notation and the independent development of the appearance. In this way it is possible to achieve consistent appearance of applications of specific set or even all of company software products. However, the first proposal of the USSL has several disadvantages which restrict the possibilities for practical use in business or other environment. These disadvantages are: the lack of @import rule for importing other style sheets, USSL only supports basic set of selectors compared with selectors of other style sheet languages for desktop environment such as Qt QSS and GTK+ GtkCssProvider, the lack of styling of the cursors, it is impossible to put down URL. The placement of widgets and its borders are not solved either. This paper contains suggestions for solving these issues.

  12. Structural styles and zircon ages of the South Tianshan accretionary complex, Atbashi Ridge, Kyrgyzstan: Insights for the anatomy of ocean plate stratigraphy and accretionary processes

    The anatomy of an ancient accretionary complex has a significance for a better understanding of the tectonic processes of accretionary orogens and complex because of its complicated compositions and strong deformation. With a thorough structural and geochronological study of a fossil accretionary complex in the Atbashi Ridge, South Tianshan (Kyrgyzstan), we analyze the structure and architecture of ocean plate stratigraphy in the western Central Asian Orogenic Belt. The architecture of the Atbashi accretionary complex is subdivisible into four lithotectonic assemblages, some of which are mélanges with "block-in-matrix" structure: (1) North Ophiolitic Mélange; (2) High-pressure (HP)/Ultra-high-pressure (UHP) Metamorphic Assemblage; (3) Coherent & Mélange Assemblage; and (4) South Ophiolitic Mélange. Relationships between main units are tectonic contacts presented by faults. The major structures and lithostratigraphy of these units are thrust-fold nappes, thrusted duplexes, and imbricated ocean plate stratigraphy. All these rock units are complicatedly stacked in 3-D with the HP/UHP rocks being obliquely southwestward extruded. Detrital zircon ages of meta-sediments provide robust constraints on their provenance from the Ili-Central Tianshan Arc. The isotopic ages of the youngest components of the four units are Late Permian, Early-Middle Triassic, Early Carboniferous, and Early Triassic, respectively. We present a new tectonic model of the South Tianshan; a general northward subduction polarity led to final closure of the South Tianshan Ocean in the End-Permian to Late Triassic. These results help to resolve the long-standing controversy regarding the subduction polarity and the timing of the final closure of the South Tianshan Ocean. Finally, our work sheds lights on the use of ocean plate stratigraphy in the analysis of the tectonic evolution of accretionary orogens.

  13. Language, Communication and Style

    Stăncuţa Ramona DIMA-LAZA

    2011-01-01

    Full Text Available Intercultural language and communication skills vary across culture. Blunders are the result of an improper understanding of other nation’s language, non-verbal communication or customs and traditions. The present paper represents an incursion into the world of inaccurate translations and misinterpretations caused by a lack of ability to overcome cultural and language barriers. It also provides solutions for such problems, exemplifying with relevant situations. It informs the reader about writing principles and style, examining the outcome of conveying an inaccurate message. People write, deliver speeches or communicate for different purposes: to learn something, to entertain or to make money. Whether it is about one reason or another, the basic idea is to comply with certain language codes in order to avoid cultural conflicts.

  15. Humor and creative life styles.

    Richman, J

    2001-01-01

    This paper is based upon the writings of William James in the late 19th century, and Alfred Adler and Sigmund Freud in the 20th, enriched by the contributions of later personality and role theorists. The self is defined as the unique organization of each person; a style is the self in action. Different life styles and their components are expressed in different situations. I posit that humor and positive thinking, combined with meaning and purpose, are vital components of all constructive life styles. The knowledge of life styles cuts through diagnostic labels to reveal our universal humanity. It can be fruitfully applied to patients and nonpatients alike and, I found, for the self-understanding of therapist. The clinical application of life styles is illustrated through numerous vignettes.

    Ayfer SU BERGİL

    2017-12-01

    Full Text Available Contrary to learning styles seem the same as what abilities refer, they are related to them in the sense that they decipher how individuals desire to use their capabilities. There have been diverse learning styles theories intent to explain the individual differences on account of the acceleration and the amount of absorbed knowledge. Learning styles have been defined under the notions of cognitive, affective and physiological attributes that serve as nearly strong indicators of how learners distinguish, combine, and reciprocate to the learning phenomena which gains importance and provide basis for language education process as well. Thus, this study aims to determine the learning styles of English language teaching (ELT students studying at Amasya University, Faculty of Education in 2017-2018 academic year. The participants of the study consist of totally 109 out of 122 from 1st, 2nd, 3rd and 4th grade students of English Language Teaching Department. The data collection instrument was Kolb’s Learning Style Inventory including four sets of work labeled as Concrete Experience, Reflective Observation, Abstract Conceptualization, and Active Experimentation and the students were expected to rank order the 12 items listed for each category via assigning a 4 to the word which best characterizes their learning style, a 3 to the next best, a 2 to the next, and a 1 to the least characteristic word. By this way, ELT students’ dominant learning styles which refer to their learning profiles has been specified descriptively. Furthermore, the learning styles of ELT students has been interconnected with the content of the courses they need to take during their teacher education process and suggestions for the members of ELT departments has been provided based on the findings of these learning styles.

    Wouters, T.; Plantinga, A.

    2006-01-01

    We examine to what extent the popularity of an investment style can be attributed to style investing. The style investing hypothesis predicts that assets in the same style show strong comovement with respect to their underlying fundamentals and that reclassifying assets into a new style raises its correlation with that style. We test this prediction by studying how comovement varies with proxies of popularity. We use different kinds of data, such as data on stocks, mutual funds, IPO?s and fin...

  20. A workflow for sub-/seismic structure and deformation quantification of 3-D reflection seismic data sets across different scales

    Krawczyk, C.M.; Lohr, T.; Oncken, O. [GFZ Potsdam (Germany); Tanner, D.C. [Goettingen Univ. (Germany). GZG; Endres, H. [RWTH Aachen (Germany)]|[TEEC, Isernhagen (Germany); Trappe, H.; Kukla, P. [TEEC, Isernhagen (Germany)

    The evolution of a sedimentary basin is mostly affected by deformation. Large-scale, subsurface deformation is typically identified by seismic data, sub-seismic small-scale fractures by well data. Between these two methods, we lack a deeper understanding of how deformation scales. We analysed a 3-D reflection seismic data set in the North German Basin, in order to determine the magnitude and distribution of deformation and its accumulation in space and time. A five-step approach is introduced for quantitative deformation and fracture prediction. An increased resolution of subtle tectonic lineaments is achieved by coherency processing, allowing to unravel the kinematics in the North German Basin from structural interpretation. Extensional events during basin initiation and later inversion are evident. 3-D retrodeformation shows major-strain magnitudes between 0-20% up to 1.3 km away from a fault trace, and variable deviations of associated extensional fractures. Good correlation of FMI data, strain distribution from retro-deformation and from geostatistic tools (see also Trappe et al., this volume) allows the validation of the results and makes the prediction of small-scale faults/fractures possible. The temporal component will be gained in the future by analogue models. The suggested workflow is applicable to reflection seismic surveys and yields in great detail both the tectonic history of a region as well as predictions for hydrocarbon plays or deep groundwater or geothermal reservoirs.

  1. Geometric Energy Derivatives at the Complete Basis Set Limit: Application to the Equilibrium Structure and Molecular Force Field of Formaldehyde.

    Morgan, W James; Matthews, Devin A; Ringholm, Magnus; Agarwal, Jay; Gong, Justin Z; Ruud, Kenneth; Allen, Wesley D; Stanton, John F; Schaefer, Henry F

    2018-03-13

    Geometric energy derivatives which rely on core-corrected focal-point energies extrapolated to the complete basis set (CBS) limit of coupled cluster theory with iterative and noniterative quadruple excitations, CCSDTQ and CCSDT(Q), are used as elements of molecular gradients and, in the case of CCSDT(Q), expansion coefficients of an anharmonic force field. These gradients are used to determine the CCSDTQ/CBS and CCSDT(Q)/CBS equilibrium structure of the S 0 ground state of H 2 CO where excellent agreement is observed with previous work and experimentally derived results. A fourth-order expansion about this CCSDT(Q)/CBS reference geometry using the same level of theory produces an exceptional level of agreement to spectroscopically observed vibrational band origins with a MAE of 0.57 cm -1 . Second-order vibrational perturbation theory (VPT2) and variational discrete variable representation (DVR) results are contrasted and discussed. Vibration-rotation, anharmonicity, and centrifugal distortion constants from the VPT2 analysis are reported and compared to previous work. Additionally, an initial application of a sum-over-states fourth-order vibrational perturbation theory (VPT4) formalism is employed herein, utilizing quintic and sextic derivatives obtained with a recursive algorithmic approach for response theory.

  2. Exploring the Role of `Gendered' Discourse Styles in Online Science Discussions

    Sullivan, Florence R.; Kapur, Manu; Madden, Sandra; Shipe, Stefanie

    2015-02-01

    In this study, we examined whether gendered discourse styles were evidenced in online, synchronous, physics collaborative learning group discussions, and the extent to which such discourse patterns were related to the uptake of ideas within the group. We defined two discourse styles: the oppositional/direct style, theorized to be the socialized discourse pattern typically used by males, and the aligned/indirect style, theorized to be the socialized discourse pattern typically used by females. Our analysis indicates the presence of both styles in these chats and the styles were generally utilized along theorized, gendered lines. However, we also observed male use of the stereotypically 'feminine' discourse style and female use of the stereotypically 'masculine' discourse style. Moreover, we found no main effect for discourse style on the uptake of ideas. The findings indicate that, contrary to prior research in both face-to-face science classroom settings and online physics settings, ideas were taken up at relatively similar rates regardless of the gendered discourse style employed. Design implications of this study are discussed and suggestions for future research are made.

  3. Leadership = Communication? The Relations of Leaders’ Communication Styles with Leadership Styles, Knowledge Sharing and Leadership Outcomes

    Bakker-Pieper, Angelique; Oostenveld, Wyneke

    2009-01-01

    Purpose The purpose of this study was to investigate the relations between leaders’ communication styles and charismatic leadership, human-oriented leadership (leader’s consideration), task-oriented leadership (leader’s initiating structure), and leadership outcomes. Methodology A survey was conducted among 279 employees of a governmental organization. The following six main communication styles were operationalized: verbal aggressiveness, expressiveness, preciseness, assuredness, supportiveness, and argumentativeness. Regression analyses were employed to test three main hypotheses. Findings In line with expectations, the study showed that charismatic and human-oriented leadership are mainly communicative, while task-oriented leadership is significantly less communicative. The communication styles were strongly and differentially related to knowledge sharing behaviors, perceived leader performance, satisfaction with the leader, and subordinate’s team commitment. Multiple regression analyses showed that the leadership styles mediated the relations between the communication styles and leadership outcomes. However, leader’s preciseness explained variance in perceived leader performance and satisfaction with the leader above and beyond the leadership style variables. Implications This study offers potentially invaluable input for leadership training programs by showing the importance of leader’s supportiveness, assuredness, and preciseness when communicating with subordinates. Originality/value Although one of the core elements of leadership is interpersonal communication, this study is one of the first to use a comprehensive communication styles instrument in the study of leadership.

  5. Good partner, good parent: responsiveness mediates the link between romantic attachment and parenting style.

    Millings, Abigail; Walsh, Judi; Hepper, Erica; O'Brien, Margaret

    2013-02-01

    This cross-sectional, dyadic questionnaire study examined the contribution of romantic attachment and responsive caregiving to parenting style, investigating both gender and partner effects. One hundred and twenty-five couples with children aged 7 to 8 years completed measures of attachment styles, responsive caregiving toward partner, and parenting styles. Structural Equation Modeling was used to examine the intra- and interpersonal associations between romantic attachment, caregiving responsiveness, and parenting styles. Attachment avoidance and anxiety were both negatively associated with responsive caregiving to partner, which in turn was positively associated with authoritative (optimal) parenting styles and negatively associated with authoritarian and permissive (nonoptimal) parenting styles. Responsive caregiving mediated all links between attachment and parenting, with an additional direct association between attachment anxiety and nonoptimal parenting styles that was not explained by caregiving responsiveness. Findings are discussed with reference to attachment theory.

  7. Accuracy of Lagrange-sinc functions as a basis set for electronic structure calculations of atoms and molecules

    Choi, Sunghwan; Hong, Kwangwoo; Kim, Jaewook; Kim, Woo Youn

    2015-01-01

    We developed a self-consistent field program based on Kohn-Sham density functional theory using Lagrange-sinc functions as a basis set and examined its numerical accuracy for atoms and molecules through comparison with the results of Gaussian basis sets. The result of the Kohn-Sham inversion formula from the Lagrange-sinc basis set manifests that the pseudopotential method is essential for cost-effective calculations. The Lagrange-sinc basis set shows faster convergence of the kinetic and correlation energies of benzene as its size increases than the finite difference method does, though both share the same uniform grid. Using a scaling factor smaller than or equal to 0.226 bohr and pseudopotentials with nonlinear core correction, its accuracy for the atomization energies of the G2-1 set is comparable to all-electron complete basis set limits (mean absolute deviation ≤1 kcal/mol). The same basis set also shows small mean absolute deviations in the ionization energies, electron affinities, and static polarizabilities of atoms in the G2-1 set. In particular, the Lagrange-sinc basis set shows high accuracy with rapid convergence in describing density or orbital changes by an external electric field. Moreover, the Lagrange-sinc basis set can readily improve its accuracy toward a complete basis set limit by simply decreasing the scaling factor regardless of systems

  8. Archaean Gold Mineralization in an Extensional Setting: The Structural History of the Kukuluma and Matandani Deposits, Geita Greenstone Belt, Tanzania

    Shimba D. Kwelwa

    2018-04-01

    Full Text Available Three major gold deposits, Matandani, Kukuluma, and Area 3, host several million ouncez (Moz of gold, along a ~5 km long, WNW trend in the E part of the Geita Greenstone Belt, NW Tanzania. The deposits are hosted in Archaean volcanoclastic sediment and intrusive diorite. The geological evolution of the deposits involved three separate stages: (1 an early stage of syn-sedimentary extensional deformation (D1 around 2715 Ma; (2 a second stage involving overprinting ductile folding (D2–4 and shearing (D5–6 events during N-S compression between 2700 and 2665 Ma, coeval with the emplacement of the Kukuluma Intrusive Complex; and (3 a final stage of extensional deformation (D7 accommodated by minor, broadly east-trending normal faults, preceded by the intrusion of felsic porphyritic dykes at ~2650 Ma. The geometry of the ore bodies at Kukuluma and Matandani is controlled by the distribution of magnetite-rich meta-ironstone, near the margins of monzonite-diorite bodies of the Kukuluma Intrusive Complex. The lithological contacts acted as redox boundaries, where high-grade mineralization was enhanced in damage zones with higher permeability, including syn-D3 hydrothermal breccia, D2–D3 fold hinges, and D6 shears. The actual mineralizing event was syn-D7, and occurred in an extensional setting that facilitated the infiltration of mineralizing fluids. Thus, whilst gold mineralization is late-tectonic, ore zone geometries are linked to older structures and lithological boundaries that formed before gold was introduced. The deformation-intrusive history of the Kukuluma and Matandani deposits is near identical to the geological history of the world-class Nyankanga and Geita Hill deposits in the central part of the Geita Greenstone Belt. This similarity suggests that the geological history of much of the greenstone belt is similar. All major gold deposits in the Geita Greenstone Belt lack close proximity to crustal-scale shear zones; they are associated

  11. Parenting style and adolescent smoking.

    O'Byrne, Kristin Koetting; Haddock, C Keith; Poston, Walker S C

    2002-06-01

    To investigate whether parenting style is an independent risk factor of smoking initiation and experimentation among adolescents, and whether there is a relationship between parenting style and readiness to quit, or nicotine dependence among smokers. The 84-item Health and Smoking Questionnaire, which assesses demographics, smoking status and smoking history, perceptions of risk and risk reduction, risk factors for tobacco use, and parenting style, was administered to 816 adolescents in grades 7 to 12 (mean age, 15.1 years) of whom 22.6% (n = 182) were smokers. Parenting style was measured by the brief, non-retrospective version of the Family of Origin Scale (FOS). Higher scores on the FOS indicated more positive perceived parenting style with high levels of intimacy and autonomy, characteristics of healthy parent-child relationships. Data were analyzed using a model-building approach to logistic regression with demographic and other psychosocial variables in the first two steps, and with parenting style as the last step. Results from two logistic regression models indicate that although parenting style is not a significant risk factor for smoking experimentation [odds ratio (OR) =.998; confidence interval (CI) =.977-1.019; p =.820], it is a significant independent risk factor for smoking initiation (OR =.950; CI =.930-.970; p =.000). Smokers who were more ready to quit had higher parenting style scores than those who were not ready to quit, and smokers who had made a serious quit attempt (an indicator of nicotine addiction) had higher parenting style scores than those who had not made a quit attempt. Moreover, nonsmokers who reported they would smoke a cigarette if their best friend offered had significantly lower parenting style scores than those who reported they would not smoke a cigarette. Additional research on parenting style and its impact on adolescent smoking with a more economically and ethnically diverse sample is warranted. If future research confirms

  12. Effects of manual threshold setting on image analysis results of a sandstone sample structural characterization by X-ray microtomography

    Moreira, Anderson C.; Fernandes, Celso P.; Fernandes, Jaquiel S.; Marques, Leonardo C.; Appoloni, Carlos R.; Nagata, Rodrigo

    2009-01-01

    X-ray microtomography is a nondestructive nuclear technique widely applied for samples structural characterization. This methodology permits the investigation of materials porous phase, without special sample preparation, generating bidimensional images of the irradiated sample. The images are generated by the linear attenuation coefficient mapping of the sample. In order to do a quantitative characterization, the images have to be binarized, separating porous phase from the material matrix. The choice of the correct threshold in the grey level histogram is an important and discerning procedure for the binary images creation. Slight variations of the threshold level led to substantial variations in physical parameters determination, like porosity and pore size distribution values. The aim of this work is to evaluate these variations based on some manual threshold setting. Employing Imago image analysis software, four operators determined the porosity and pore size distribution of a sandstone sample by image analysis. The microtomography measurements were accomplished with the following scan conditions: 60 kV, 165 μA, 1 mm Al filter, 0.45 deg step size and 180.0 deg total rotation angle with and 3.8 μm and 11 μm spatial resolution. The global average porosity values, determined by the operators, range from 27.8 to 32.4 % for 3.8 μm spatial resolution and 12.3 to 28.3 % for 11 μm spatial resolution. Percentage differences among the pore size distributions were also found. For the same pore size range, 5.5 % and 17.1 %, for 3.8 μm and 11 μm spatial resolutions respectively, were noted. (author)

  13. Promoting the health, safety and welfare of adults with learning disabilities in acute care settings: a structured literature review.

    Bradbury-Jones, Caroline; Rattray, Janice; Jones, Martyn; Macgillivray, Stephen

    2013-06-01

    To present the findings of a structured literature review that aimed to identify the influences on the health, safety and welfare of adults with learning disabilities in acute hospitals. There is increasing evidence regarding the inadequacy of care for people with learning disabilities in acute care settings. However, few studies have specifically addressed their health, safety and welfare in such contexts. Four key electronic databases (Medline; PsycINFO; British Nursing Index and archive; Cumulative Index to Nursing and Allied Health Literature) were searched for relevant literature published between 2000 and 2011. Publications assessed as meeting the inclusion criteria were retrieved in full. Data were extracted regarding methods used; primary aims of the study being reported; and key findings. Of the 3505 papers identified in the initial search, eight met the inclusion criteria. Analysis revealed six areas of influence on the health, safety and welfare of adults with learning disabilities in acute hospitals: care provision (meeting health and personal needs); communication; staff attitudes; staff knowledge; supporters; and carers (valuing their role); physical environment. We represent these six areas diagrammatically, as concentric rings. These influence on health, safety and welfare form an inner (direct) layer and an outer (indirect) layer consisting of liaison services and education/training. This new conceptualisation of influences as being multi-layered assists in the identification of similarly multi-layered improvement strategies. Adults with learning disabilities can exert their own influence on health, safety and welfare and should be supported to make decisions about their own care. More broadly they should be involved with policy development, nurse education and research. This can be achieved through inclusive approaches, for example, inviting people with learning disabilities to input into nursing curricula or to engage in research as

  14. Does learning style influence academic performance in different forms of assessment?

    Wilkinson, Tracey; Boohan, Mairead; Stevenson, Michael

    2014-03-01

    Educational research on learning styles has been conducted for some time, initially within the field of psychology. Recent research has widened to include more diverse disciplines, with greater emphasis on application. Although there are numerous instruments available to measure several different dimensions of learning style, it is generally accepted that styles differ, although the qualities of more than one style may be inherent in any one learner. But do these learning styles have a direct effect on student performance in examinations, specifically in different forms of assessment? For this study, hypotheses were formulated suggesting that academic performance is influenced by learning style. Using the Honey and Mumford Learning Style Questionnaire, learning styles of a cohort of first year medical and dental students at Queen's University Belfast were assessed. Pearson correlation was performed between the score for each of the four learning styles and the student examination results in a variety of subject areas (including anatomy) and in different types of assessments - single best answer, short answer questions and Objective Structured Clinical Examinations. In most of the analyses, there was no correlation between learning style and result and in the few cases where the correlations were statistically significant, they generally appeared to be weak. It seems therefore from this study that although the learning styles of students vary, they have little effect on academic performance, including in specific forms of assessment. © 2013 Anatomical Society.

  15. Advertising styles in different cultures

    2003-01-01

    Full Text Available Modern consumer is inhabitant of a "Global Village" as well as of its own national culture which largely influences his creation of a system of values, beliefs and style of life in general. According to adopted values and styles, consumers from different cultures have different buying behavior, different needs and preferences related to a product and they have their favorite advertising styles. As advertising reflects culture, symbols and rituals which are used are even more emphasized and strengthen cultural values, which are then used as a strong advertising style characteristic. Global advertisers are increasingly faced with different environment meaning. A fact that has been proved in practice is that standardized approach to advertising does not transmit values in a correct way, so the advertisers that want to achieve long term success must differentiate their brands to competitors'. In modern market environment strategy "Think globally, act locally" proved to be adequate for advertising in modern international market.

  18. Administrator Leadership Styles and Their Impact on School Nursing.

    Davis, Charles R

    2018-01-01

    In comparison to other professional staff in an educational based setting, the registered professional school nurse has unique roles, responsibilities, education, training, and scope of practice. In carrying out this unique and specialized role, school nurses operate under a building administrator, the leader of the building and often the immediate supervisor of the school nurse. In addition, many school nurses in small districts are the only registered professional nurse employed by the school. The building administrator's leadership style not only sets the tone for the day-to-day operations in the school but also impacts the school nurse functioning and program implementation. This article reviews the three most common types of leadership styles as defined by Kurt Lewin-laissez-faire, democratic, and coercive/authoritarian-and their potential impact on school nursing practice. In addition, the article provides recommendations for school nurses for successful practice with regard to supervisor leadership styles.

Existing models of stylistic analysis, supported at times by computer-assisted analysis, are developed to examine a range of works and writers, selected for their literary, cultural, and ideological importance. The style of the different translators is subjected to a close linguistic investigation within their cultural and ideological framework.

  20. Thinking style changes among deaf, hard-of-hearing, and hearing students.

    Cheng, Sanyin; Zhang, Li-fang

    2015-01-01

    This study explores how university students' thinking styles changed over a single academic year by twice administering the Thinking Styles Inventory-Revised II to 256 deaf or hard-of-hearing (DHH) students and 286 hearing students from art and design academic disciplines in China. Results showed that after having studied at the university for one academic year, hearing students showed increased use of Type I thinking styles (more creativity generated, less structured, and more complex) and less use of Type II thinking styles (more norm favoring, more structured, and more simplistic), whereas DHH students demonstrated increased use of both Type I and Type II thinking styles. Moreover, students' changes in thinking styles differed across university class levels. The contributions, limitations, and implications of the present research are discussed. © The Author 2014.

  2. Parenting styles and eating disorders.

    Jáuregui Lobera, I; Bolaños Ríos, P; Garrido Casals, O

    2011-10-01

    The aim of the study was to analyse the parental bonding profiles in patients with eating disorders (ED), as well as the relationship among the different styles of parenting and some psychological and psychopathological variables. In addition, the association between the perceived parental bonding and different coping strategies was analysed. Perception of parenting styles was analysed in a sample of 70 ED patients. The Parental Bonding Instrument, Self-Esteem Scale of Rosenberg, Coping Strategies Inventory, State-Trait Anxiety Inventory, Beck Depression Inventory and Eating Disorders Inventory-2 were used. Kruskal-Wallis test (comparisons), Spearman correlation coefficients (association among different variables) and χ(2)-test (parental bonding profiles differences) were applied. The stereotyped style among ED patients is low care-high control during the first 16 years, and the same can be said about current styles of the mothers. Between 8.6% and 12.9% of the patients perceive their parents' styles as neglectful. The neglectful parenting is the style mainly involved in the specific ED symptoms as drive for thinness, body dissatisfaction and bulimia. In order to achieve a better balanced parents' role during the treatment, it would be necessary to improve the role of the mothers as caregivers, decreasing their role mainly based on the overprotection. © 2011 Blackwell Publishing.

    Highlights: Black-Right-Pointing-Pointer New {sup 1}H, {sup 13}C, {sup 31}P triple-resonance NMR pulse experiments. Black-Right-Pointing-Pointer Analysis of organophosphorus (OP) compounds in complex matrix. Black-Right-Pointing-Pointer Selective extraction of {sup 1}H, {sup 31}P, and {sup 13}C chemical shifts and connectivities. Black-Right-Pointing-Pointer More precise NMR identification of OP nerve agents and their degradation products. - Abstract: The {sup 1}H, {sup 13}C correlation NMR spectroscopy utilizes J{sub CH} couplings in molecules, and provides important structural information from small organic molecules in the form of carbon chemical shifts and carbon-proton connectivities. The full potential of the {sup 1}H, {sup 13}C correlation NMR spectroscopy has not been realized in the Chemical Weapons Convention (CWC) related verification analyses due to the sample matrix, which usually contains a high amount of non-related compounds obscuring the correlations of the relevant compounds. Here, the results of the application of {sup 1}H, {sup 13}C, {sup 31}P triple-resonance NMR spectroscopy in characterization of OP compounds related to the CWC are presented. With a set of two-dimensional triple-resonance experiments the J{sub HP}, J{sub CH} and J{sub PC} couplings are utilized to map the connectivities of the atoms in OP compounds and to extract the carbon chemical shift information. With the use of the proposed pulse sequences the correlations from the OP compounds can be recorded without significant artifacts from the non-OP compound impurities in the sample. Further selectivity of the observed correlations is achieved with the application of phosphorus band-selective pulse in the pulse sequences to assist the analysis of multiple OP compounds in mixture samples. The use of the triple-resonance experiments in the analysis of a complex sample is shown with a test mixture containing typical scheduled OP compounds, including the characteristic degradation

  9. Sex and leadership styles: a meta-analysis of research published in the 1990s.

    van Engen, Marloes L; Willemsen, Tineke M

    2004-02-01

    Empirical research on sex differences in leadership styles, published between 1987 and 2000 in peer-reviewed journals, is reviewed by means of a meta-analysis. The leadership styles examined are interpersonal, task-oriented, democratic versus autocratic, and transformational and transactional leadership. Analysis showed that evidence for sex differences in leadership behavior is mixed, demonstrating that women tend to use more democratic and transformational leadership styles than men do, whereas no sex differences are found on the other leadership styles. Sex differences in leadership styles are contingent upon the context in which male and female leaders work, as both the type of organization in which the leader works and the setting of the study turn out to be moderators of sex differences in leadership styles.

    Many indeterminate plants can have wide fluctuations in the pattern of fruit-set and harvest. Fruit-set in these types of plants depends largely on the balance between source (assimilate supply) and sink strength (assimilate demand) within the plant. This study aims to evaluate the ability of functional-structural plant models to simulate different fruit-set patterns among Capsicum cultivars through source-sink relationships. A greenhouse experiment of six Capsicum cultivars characterized with different fruit weight and fruit-set was conducted. Fruit-set patterns and potential fruit sink strength were determined through measurement. Source and sink strength of other organs were determined via the GREENLAB model, with a description of plant organ weight and dimensions according to plant topological structure established from the measured data as inputs. Parameter optimization was determined using a generalized least squares method for the entire growth cycle. Fruit sink strength differed among cultivars. Vegetative sink strength was generally lower for large-fruited cultivars than for small-fruited ones. The larger the size of the fruit, the larger variation there was in fruit-set and fruit yield. Large-fruited cultivars need a higher source-sink ratio for fruit-set, which means higher demand for assimilates. Temporal heterogeneity of fruit-set affected both number and yield of fruit. The simulation study showed that reducing heterogeneity of fruit-set was obtained by different approaches: for example, increasing source strength; decreasing vegetative sink strength, source-sink ratio for fruit-set and flower appearance rate; and harvesting individual fruits earlier before full ripeness. Simulation results showed that, when we increased source strength or decreased vegetative sink strength, fruit-set and fruit weight increased. However, no significant differences were found between large-fruited and small-fruited groups of cultivars regarding the effects of source

  12. A multidimensional intergenerational model of young males' driving styles.

    Gil, Shani; Taubman-Ben-Ari, Orit; Toledo, Tomer

    2016-12-01

    This study examines the associations between fathers' driving styles, the family's general and driving-related atmosphere, and the young drivers' motivations, on one hand, and young males' driving styles, on the other. The 242 father and son pairs that participated in the study independently completed several self-report questionnaires at different points in time within the first year after licensure of the young drivers. A structural equation model (SEM) was developed, in which the contribution of fathers' driving style and their sons' perceptions of the general family relations, the family climate for road safety (FCRS), and costs and benefits of driving, to the driving styles of the young male drivers was examined. The SEM estimation results show direct as well as indirect significant effects between the various dimensions. The FCRS factors of non-commitment and messages, and the cost of thrill, were found to be the strongest mediators between the fathers' driving style and the family cohesion, on one hand, and the driving style of the young driver, on the other. These results may be useful in pointing out directions for the development of interventions that could assist in reducing the involvement of youngsters in risky driving and car crashes, and encourage safe and considerate driving.

  3. Unraveling the diversity in arc volcanic eruption styles: Examples from the Aleutian volcanic arc, Alaska

    Larsen, Jessica F.

    2016-11-01

    The magmatic systems feeding arc volcanoes are complex, leading to a rich diversity in eruptive products and eruption styles. This review focuses on examples from the Aleutian subduction zone, encompassed within the state of Alaska, USA because it exhibits a rich diversity in arc structure and tectonics, sediment and volatile influx feeding primary magma generation, crustal magma differentiation processes, with the resulting outcome the production of a complete range in eruption styles from its diverse volcanic centers. Recent and ongoing investigations along the arc reveal controls on magma production that result in diversity of eruptive products, from crystal-rich intermediate andesites to phenocryst-poor, melt-rich silicic and mafic magmas and a spectrum in between. Thus, deep to shallow crustal "processing" of arc magmas likely greatly influences the physical and chemical character of the magmas as they accumulate in the shallow crust, the flow physics of the magmas as they rise in the conduit, and eruption style through differences in degassing kinetics of the bubbly magmas. The broad spectrum of resulting eruption styles thus depends on the bulk magma composition, melt phase composition, and the bubble and crystal content (phenocrysts and/or microlites) of the magma. Those fundamental magma characteristics are in turn largely determined by the crustal differentiation pathway traversed by the magma as a function of tectonic location in the arc, and/or the water content and composition of the primary magmas. The physical and chemical character of the magma, set by the arc differentiation pathway, as it ascends towards eruption determines the kinetic efficiency of degassing versus the increasing internal gas bubble overpressure. The balance between degassing rate and the rate at which gas bubble overpressure builds then determines the conditions of fragmentation, and ultimately eruption intensity.

  4. Transformational Leadership Style as Predictor of Decision Making Styles: Moderating Role of Emotional Intelligence

    Rana Rashid Rehman

    2012-12-01

    Full Text Available The current study examines the relationship among transformational leadership style and decision making styles. It also determines the moderating role of emotional intelligence in predicting this relationship. Three hypotheses are generated for the study i.e., twohypotheses are to measure the relationship among transformational leadership style and decision making styles whereas third hypothesis is to assess the moderating effect of emotional intelligence. Questionnaire method is used to collect data from 113respondents. Regression analysis is utilized to study the relationship among transformational leadership style and decision making styles and step-wise regression analysis is used to study moderating effect of emotional intelligence. The study foundthat transformational leadership style strongly predicts rational and dependant decision making styles and weakly predict intuitive and spontaneous decision making styles while no association founds with avoidant decision making styles. Present research also foundthat emotional intelligence moderates the relationship among transformational leadership style and decision making styles.

  5. Structural setting and kinematics of Nubian fault system, SE Western Desert, Egypt: An example of multi-reactivated intraplate strike-slip faults

    Sakran, Shawky; Said, Said Mohamed

    2018-02-01

    Detailed surface geological mapping and subsurface seismic interpretation have been integrated to unravel the structural style and kinematic history of the Nubian Fault System (NFS). The NFS consists of several E-W Principal Deformation Zones (PDZs) (e.g. Kalabsha fault). Each PDZ is defined by spectacular E-W, WNW and ENE dextral strike-slip faults, NNE sinistral strike-slip faults, NE to ENE folds, and NNW normal faults. Each fault zone has typical self-similar strike-slip architecture comprising multi-scale fault segments. Several multi-scale uplifts and basins were developed at the step-over zones between parallel strike-slip fault segments as a result of local extension or contraction. The NNE faults consist of right-stepping sinistral strike-slip fault segments (e.g. Sin El Kiddab fault). The NNE sinistral faults extend for long distances ranging from 30 to 100 kms and cut one or two E-W PDZs. Two nearly perpendicular strike-slip tectonic regimes are recognized in the NFS; an inactive E-W Late Cretaceous - Early Cenozoic dextral transpression and an active NNE sinistral shear.

However, how this influence comes into effect has not been widely explored. Absenteeism may be a factor in this association; however, no studies are available on this subject in the mental health care setting, although this setting has been under a lot of strain lately to provide their services at lower costs. This may have an impact on employers, employees, and the delivery of services, and absenteeism due to illness of employees tends to already be rather high in this particular industry. This study explores the association between leadership style, absenteeism, and employee satisfaction in a stressful work environment, namely a post-merger specialty mental health care institution (MHCI in a country where MHCIs are under governmental pressure to lower their costs (The Netherlands.Methods: We used a mixed methods design with quantitative as well as qualitative research to explore the association between leadership style, sickness absence rates, and employee satisfaction levels in a specialty MHCI. In depth, semi-structured interviews were conducted with ten key informants and triangulated with documented research and a contrast between four departments provided by a factor analysis of the data from the employee satisfaction surveys and sickness rates.

    2007-03-01

    Full Text Available Abstract Background The fibromyalgia syndrome (FMS is suggested to be a manifestation of depression or affective spectrum disorder. We measured the cognitive style of patients with FMS to assess personality styles in 44 patients with fibromyalgia syndrome (FMS by comparing them with 43 patients with major depressive disorder (MDD and 41 healthy controls (HC. Methods Personality styles were measured by the Sociotropy and Autonomy Scale (SAS and the Dysfunctional Attitude Scale (DAS. The Structured Clinical interview for DSM Axis I was applied to Axis I disorders, while the Beck Depression Inventory was used to measure depression severity. Results Patients with FMS in general have a sociotropic personality style similar to patients with MDD, and different from HC, but FMS patients without a lifetime history of MDD had a cognitive personality style different from patients with MDD and similar to HC. Conclusion These findings suggest that a depressotypic personality style is related to depressive disorder, but not to FMS.

  11. An Algebraic Programming Style for Numerical Software and Its Optimization

    T.B. Dinesh

    2000-01-01

    Full Text Available The abstract mathematical theory of partial differential equations (PDEs is formulated in terms of manifolds, scalar fields, tensors, and the like, but these algebraic structures are hardly recognizable in actual PDE solvers. The general aim of the Sophus programming style is to bridge the gap between theory and practice in the domain of PDE solvers. Its main ingredients are a library of abstract datatypes corresponding to the algebraic structures used in the mathematical theory and an algebraic expression style similar to the expression style used in the mathematical theory. Because of its emphasis on abstract datatypes, Sophus is most naturally combined with object-oriented languages or other languages supporting abstract datatypes. The resulting source code patterns are beyond the scope of current compiler optimizations, but are sufficiently specific for a dedicated source-to-source optimizer. The limited, domain-specific, character of Sophus is the key to success here. This kind of optimization has been tested on computationally intensive Sophus style code with promising results. The general approach may be useful for other styles and in other application domains as well.

  12. Social Variations in Perceived Parenting Styles among Norwegian Adolescents.

    Elstad, Jon Ivar; Stefansen, Kari

    2014-01-01

    Previous research has documented the associations between parenting and parenting styles and child and adolescent outcomes. Little is known, however, about the social structuring of parenting in contemporary Nordic welfare states. A possible hypothesis is that socioeconomic variations in parenting styles in present-day Norway will be small because of material affluence, limited income inequality, and an active welfare state. This study examines social variations in parenting as perceived by Norwegian adolescents ( N  = 1362), with a focus on four parenting style dimensions: responsiveness, demandingness, neglecting, and intrusive. Responsiveness seems to capture major divisions in parenting. Adolescents in families with fewer economic resources experienced their parents as somewhat less responsive, but responsiveness was not related to parents' education. Low parental education was on the other hand associated with perceptions of parents as neglecting and intrusive. Viewing parents as demanding did neither vary with parental education nor with family economy. Substantial variations in parenting styles persist in present-day Norway, and these variations correspond moderately with the families' placement in the social structure. Indicators of parenting and parenting styles may be useful indicators of some aspects of child and adolescent well-being.

    Hartley, Chelsey M; Barroso, Nicole; Rey, Yasmin; Pettit, Jeremy W; Bagner, Daniel M

    2014-12-01

    Although a number of studies have examined the factor structure of the Edinburgh Postnatal Depression Scale (EPDS) in predominately White or African American samples, no published research has reported on the factor structure among Hispanic women who reside in the United States. The current study examined the factor structure of the EPDS among Hispanic mothers in the United States. Among 220 Hispanic women, drawn from a pediatric primary care setting, with an infant aged 0 to 10 months, 6 structural models guided by the empirical literature were evaluated using confirmatory factor analysis. Results supported a 2-factor model of depression and anxiety as the best fitting model. Multigroup models supported the factorial invariance across women who completed the EDPS in English and Spanish. These findings provide initial support for the 2-factor structure of the EPDS among Hispanic women in the United States. © 2014 Wiley Periodicals, Inc.

  14. AFRICAN-STYLE MEDIATION AND WESTERN-STYLE DIVORCE AND FAMILY MEDIATION: REFLECTIONS FOR THE SOUTH AFRICAN CONTEXT

    AE Boniface

    2012-12-01

    Full Text Available Both Western-styled mediation and African-styled mediation are practised in South Africa. Each of these models is applied in specific social contexts. In this article a brief explanation of what is meant by the term divorce and family mediation is provided. Thereafter the principles and processes of both Western-styled divorce and family mediation and African-styled group mediation are explored. Attention is given to the roles of mediators in both of these models as well as the ubuntu-styled values found in African group mediation. In Africa, there is a tradition of family neighbourhood negotiation facilitated by elders and an attitude of togetherness in the spirit of humanhood. Both of these show a commitment to the community concerned and a comprehensive view of life. In Africa conflicts are viewed as non-isolated events and are viewed in their social contexts. Not only are consequences for the disputing parties taken into account but also consequences for others in their families. These methods can be found in present-day methods, which are either used independently of imported Western structures or used alternatively to such structures. In this article the concept of mediation circles, as currently found in Western-styled mediation are also covered. Additionally, the provisions of the Children’s Act 38 of 2005 referring to mediation as well as the provisions of the Child Justice Act 75 of 2008 and family group conferencing in the realm of restorative justice in South Africa are critiqued. It is suggested that divorce and family mediation can learn from the principles of restorative justice applied during family group conferencing as well as from African-styled group mediation.

    2015-08-01

    Full Text Available Background The relationship between a court probation officer and their ward is a specific one and is frequently connected with enormous individuals costs. This fact is connected with the character of the job, and with the conditions determining its character. Psychosocial threats may influence both mental and somatic health, directly or indirectly, by means of the influence exerted by stress. Participants and procedure The main study was conducted at the offices of the teams of the Court Probation Service. The teams of the Court Probation Service are part of the structure of the following 9, randomly selected, district courts (DCs: DC Wrocław, DC Bydgoszcz, DC Szczecin, DC Poznań, DC Łódź, DC Lublin, DC Kraków, DC Katowice and DC Białystok. Participation in the research was voluntary and anonymous; the tools were arranged in sets, and the sequence of those sets was random. The sets of research tools were received by 1,000 individuals altogether. Results The conducted research confirmed the need to verify the significance of the feeling of occupational stress of court probation officers at the workplace and the correlations between it and a number of variables. Below, I present statistical analyses concerning various aspects of occupational stress experienced in the studied group, including correlations between the general level of occupational stress and the dimensions of it, and organizational predictors. The objective of the research was to indicate the styles of coping with stress and the correlations of them with the stress felt by court probation officers. Conclusions The research confirms a significant influence exerted by organizational determinants upon the general level of felt occupational stress. Professional court probation officers experience a higher level of felt occupational stress; what is conducive to that is high encumbrance with occupational responsibilities, and also functioning directly in structures of the court of

  18. The impact of leadership styles on innovation management

    Łukowski Wojciech

    2017-06-01

    Full Text Available The article reviews research on the impact of different leadership styles on innovation management by setting out the organisational framework of the findings to date in four generic dimensions: people, measures, effects, and objectives. Using this framework, an overview has been provided of studies on directive and participative leadership, interactive leadership, charismatic leadership, transformational leadership, transactional and instrumental leadership, strategic and executive leadership, as well as shared and distributed leadership. There are strong signals that different stages and types of innovation raise different leadership requirements. Against this background, transformational leadership is not the only innovation management style and various leadership styles have their own, distinct ways of contributing to different types and stages of innovation. However, the determination of this allocation is still very incomplete and the answer to the question of how innovations should be managed remains unclear. The article also describes research needs and their practical implications.

  19. LEADERSHIP STYLES: A STUDY OF AUSTRALIAN AND THAI PUBLIC SECTORS

    Nattavud Pimpa

    2012-01-01

    Full Text Available Leadership is deeply attached to culture. This study compares leadership styles in Thai and Australian public sectors. The data were collected from staff in public sector settings in Australia and Thailand. The results confirm four leadership styles that suit the public sector culture in both countries: communication-oriented, strategic thinking and planning, relationship building, and conflict management. In the Thai public sector system, leadership that focuses on goal orientation is ranked most highly: Australian public sector organisations focus on leadership that fosters equity among organisational members, creates a supportive environment in the workplace, and facilitates participation. It is evident from this study that significant distinctions between the organisational cultures of Thailand and Australia are matched by marked dissimilarities of preferred leadership styles. Thus, an understanding of local organisational culture is important for effective leadership at all levels.

  20. Leadership styles of nurse managers in a multinational environment.

    Suliman, Wafika A

    2009-01-01

    This is a descriptive study conducted at a multinational working environment, where 1500 nurses representing 52 nationalities are employed. The study aimed at exploring the predominant leadership style of nurse managers through self-evaluation and staff nurses' evaluation and the impact of working in a multinational environment on their intention to stay or quit. The value lies in its focus on leadership styles in an environment where national diversity among managers, staff, and patients is very challenging. The study included 31 nurse managers and 118 staff nurses using Bass and Avolio's (1995) Multifactor Leadership Questionnaire. The results showed that nurse managers and staff nurses reported transformational leadership as predominant with significant difference in favor of nurse managers. Participants' nationality and intention to stay or quit affected their perception of transformational leadership as a predominant style. The implications highlight the need for senior nursing management to set effective retention strategies for transformational nurse managers who work at multinational environments.

    Among all the various learning style models, the Dunn & Dunn Learning Style Model (DDLSM) in particular has become a widely used method transforming teaching practice. Dunn & Dunn research literature is scarce when it comes to how the model is used by teachers in general. This is an issue since...... the model is a research-based prescriptive model of teaching. Employing observations and interviews to collect data, the present study investigates teachers’ use of the model. Findings indicate that the DDLSM is used for a number of purposes, some of which are in contradiction to the model prescriptions....

    2016-10-12

    The concept of leadership has been studied in various disciplines and from different theoretical approaches. It is a dynamic concept that evolves over time. There are few studies in our field on managers' self-perception of their leadership style. There are no pure styles, but one or another style is generally favoured to a greater or lesser degree. In the primary health care (PHC) setting, managers' leadership style is defined as a set of attitudes, behaviours, beliefs and values. The objectives of this study were to describe and learn about the self-perception of behaviours and leadership styles among PHC managers; to determine the influence of the leadership style on job satisfaction, efficiency, and willingness to work in a team; and to determine the relationship between transformational and transactional styles according age, gender, profession, type of manager years of management experience, and the type of organization. To describe leadership styles as perceived by PHC managers, a cross sectional study was performed using an 82 items-self-administered Multifactor Leadership Questionnaire (MLQ). This questionnaire measures leadership styles, attitudes and behaviour of managers. The items are grouped into three first order variables (transformational, transactional and laissez-faire) and ten second order variables (which discriminate leader behaviours). Additionally, the questionnaire evaluates organizational consequences such as extra-effort, efficiency and satisfaction. One hundred forty responses from 258 managers of 133 PHC teams in the Barcelona Health Area (response rate: 54.26 %). Most participants were nurses (61.4 %), average age was 49 years and the gender predominantly female (75 %). Globally, managers assessed themselves as equally transactional and transformational leaders (average: 3.30 points). Grouped by profession, nurses (28.57 % of participants) showed a higher transactional leadership style, over transformational leadership style

  3. Remembered parenting styles and adjustment in middle and late adulthood.

    2009-01-01

    Authoritative parenting is the parenting style often associated with positive outcomes for children and adolescents. This study considers whether remembered parenting styles in childhood predict multiple dimensions of functioning in adulthood. We used the 1995 National Survey of Midlife Development in the United States data set (N = 2,232) to assess the association between parenting behaviors remembered from childhood-classified as authoritative, authoritarian, indulgent, and uninvolved-and psychological well-being, depressive symptoms, and substance abuse, in a subsample of mid- and later-life adults. Differences in outcomes by sex, race, and childhood socioeconomic status were also examined across parenting styles. Adults who remembered authoritative compared with authoritarian and uninvolved parents reported greater psychological well-being and fewer depressive symptoms, and those with uninvolved parents noted greater substance abuse. No outcome differences were found between remembered authoritative and indulgent parenting styles. A few sex and race interactions were identified: Authoritative parenting (compared with uninvolved) was more strongly associated with men's psychological well-being than women's, and authoritative parenting (compared with authoritarian) predicted reduced depressive symptoms for Whites more than non-Whites. There is some support that remembered parenting styles continue to be related to functioning across the lifespan. There is also evidence of resiliency, flexibility, and malleability in human development.

    2016-11-01

    Full Text Available The manager’s leadership styles define the way a manager acts behaves and takes decisions in certain situations and has a direct influence upon the employees’ well-being. In a small and medium enterprise setting, unlike in a large enterprise, the employees are feeling the influence of the leadership style in a much more direct and personal way, due to the small number of hierarchical levels and the constant interaction between the owner/manager and the employees. The present paper focuses on analyzing how the employees of SMEs from Oltenia and Muntenia Regions of Romania perceive their superiors’ leadership styles. In order to meet this goal, we have used a 21 question survey, based on which we could determine the leadership style (Autocratic, Democratic or Laissez-faire of the superior, as it is perceived by each respondent. The survey has been applied on a sample of cca. 300 employees from small and medium enterprises from Oltenia, and approximately 130 responses have been used in the actual research. The results of this study will be used in a further research, in which we aim to compare the way the managers perceive their own leadership style and how it is perceived by their employees.

    Full Text Available The aim of the present study is to examine the interrelations of executive function (EF tasks with general cognitive ability and linguistic level in preschool children. The analyses of the correlation between EF sub-domains, particularly inhibition and set-shifting, have been studied to comprehend the ontogenesis of EFs. Task analysis has allowed us to identify which EF sub-domains are prevalent in each task, with particular attention to inhibition and set-shifting definitions. The sample was composed of 40 typically developing children from 48 to 69 months old (M=58 months, SD=5.02; 28 boys and 12 girls. The results give some insight into the development of executive functions, their utility in clinical assessment and indication.

    To investigate the influences of parenting styles on development of children aged three to six years. A cross-sectional study was conducted in 360 children and their parents selected by multi-stage random sampling. The data were collected from July 24th to August 31st, 2004. The Denver II test kit and the scale by Baumrind D were used to test the child development and parenting styles respectively. A questionnaire was used to collect the family and child factors. Data were analyzed by frequency distribution and Multiple logistic regression with the significant level set at p-value of Parenting styles had significant influences on child development (p-value parenting style had a 1.9 times higher chance of having delayed development compared with those with democratic parenting style. In addition, significant family and child factors for explaining child development were family type, mother's education, father's occupation, relationship within the family, nutritional status and sex. Parenting styles had a significant influence on child development. The children raised with mixed parenting style had a 1.9 timds higher chance of having delayed development compared to those whose parents used democratic parenting style. Therefore, the parents should rear their children by using the democratic parenting style that leads to the age-appropriate development child

    2017-10-01

    The reasons for the failure of the pitch stability of the knife-plane installation due to the action of extreme effort in the plane of the seam from the conveyor side on the mechanism of removing sections of mechanized sets are shown. The technique for determining this effort is presented. The constructions of the adaptive mechanisms of the removing sections of mechanized sets with the basements of catamaran type, in the constrictions of which elastic elements (rods) are used, are considered. The constructions of the mechanism of removing a section of the mechanized set with the basement of catamaran type in which the stock of the hydraulic jack is connected with the band loop through the movable rods intermediate basement with a link are worked out. The intermediate basement unloads the stock of the hydraulic jack of the moving installation from the side curving efforts, caused by the action of lateral forces in the plane of the seam on the conveyor side. It increases the reliability and efficiency of work of the knife plane mechanized complex.

    2017-01-01

    Toddlers' eating behaviors are influenced by the way parents interact with their children. The objective of this study was to explore how five major constructs of general parenting behavior cluster in parents of toddlers. These parenting clusters were further explored to see how they differed in the use of feeding strategies (i.e. feeding styles and food parenting practices) and by reported child eating styles. An online survey with 1005 mothers/caregivers (legal guardians) with at least one child between 12 and 36 months old was conducted in the United States in 2012, assessing general parenting behavior, feeding style, food parenting practices and the child eating styles. A three cluster solution of parenting style was found and clusters were labelled as overprotective/supervising, authoritarian, and authoritative. The clusters differed in terms of general parenting behaviors. Both overprotective and authoritative clusters showed high scores on structure, behavioral control, and nurturance. The overprotective cluster scored high on overprotection. The 'authoritarian' cluster showed lowest levels of nurturance, structure and behavioral control. Overprotective and authoritative parents showed very similar patterns in the use of food parenting practices, e.g. monitoring food intake, modeling, and promoting healthy food intake and availability at home. Overprotective parents also reported higher use of pressure to eat and involvement. Authoritarian parents reported high use of giving the child control over their food behaviors, emotion regulation, using food as a reward, and controlling food intake for weight control. Children's eating styles did not largely vary by parenting cluster. This study showed that a relatively new parenting style of overprotection is relevant for children's eating behaviors. Overprotective parents reported food parenting practices that are known to be beneficial for children's food intake, such as modelling healthy food intake, as well as

    Stereo-array isotope labeling (SAIL) has been combined with the fully automated NMR structure determination algorithm FLYA to determine the three-dimensional structure of the protein ubiquitin from different sets of input NMR spectra. SAIL provides a complete stereo- and regio-specific pattern of stable isotopes that results in sharper resonance lines and reduced signal overlap, without information loss. Here we show that as a result of the superior quality of the SAIL NMR spectra, reliable, fully automated analyses of the NMR spectra and structure calculations are possible using fewer input spectra than with conventional uniformly {sup 13}C/{sup 15}N-labeled proteins. FLYA calculations with SAIL ubiquitin, using a single three-dimensional 'through-bond' spectrum (and 2D HSQC spectra) in addition to the {sup 13}C-edited and {sup 15}N-edited NOESY spectra for conformational restraints, yielded structures with an accuracy of 0.83-1.15 A for the backbone RMSD to the conventionally determined solution structure of SAIL ubiquitin. NMR structures can thus be determined almost exclusively from the NOESY spectra that yield the conformational restraints, without the need to record many spectra only for determining intermediate, auxiliary data of the chemical shift assignments. The FLYA calculations for this report resulted in 252 ubiquitin structure bundles, obtained with different input data but identical structure calculation and refinement methods. These structures cover the entire range from highly accurate structures to seriously, but not trivially, wrong structures, and thus constitute a valuable database for the substantiation of structure validation methods.

FLYA calculations with SAIL ubiquitin, using a single three-dimensional 'through-bond' spectrum (and 2D HSQC spectra) in addition to the 13 C-edited and 15 N-edited NOESY spectra for conformational restraints, yielded structures with an accuracy of 0.83-1.15 A for the backbone RMSD to the conventionally determined solution structure of SAIL ubiquitin. NMR structures can thus be determined almost exclusively from the NOESY spectra that yield the conformational restraints, without the need to record many spectra only for determining intermediate, auxiliary data of the chemical shift assignments. The FLYA calculations for this report resulted in 252 ubiquitin structure bundles, obtained with different input data but identical structure calculation and refinement methods. These structures cover the entire range from highly accurate structures to seriously, but not trivially, wrong structures, and thus constitute a valuable database for the substantiation of structure validation methods

    Stereo-array isotope labeling (SAIL) has been combined with the fully automated NMR structure determination algorithm FLYA to determine the three-dimensional structure of the protein ubiquitin from different sets of input NMR spectra. SAIL provides a complete stereo- and regio-specific pattern of stable isotopes that results in sharper resonance lines and reduced signal overlap, without information loss. Here we show that as a result of the superior quality of the SAIL NMR spectra, reliable, fully automated analyses of the NMR spectra and structure calculations are possible using fewer input spectra than with conventional uniformly 13C/15N-labeled proteins. FLYA calculations with SAIL ubiquitin, using a single three-dimensional "through-bond" spectrum (and 2D HSQC spectra) in addition to the 13C-edited and 15N-edited NOESY spectra for conformational restraints, yielded structures with an accuracy of 0.83-1.15 A for the backbone RMSD to the conventionally determined solution structure of SAIL ubiquitin.

    Homology modeling is a powerful tool for predicting protein structures, whose success depends on obtaining a reasonable alignment between a given structural template and the protein sequence being analyzed. In order to leverage greater predictive power for proteins with few structural templates, we have developed a method to rank homology models based upon their compliance to secondary structure derived from experimental solid-state NMR (SSNMR) data. Such data is obtainable in a rapid manner by simple SSNMR experiments (e.g., {sup 13}C-{sup 13}C 2D correlation spectra). To test our homology model scoring procedure for various amino acid labeling schemes, we generated a library of 7,474 homology models for 22 protein targets culled from the TALOS+/SPARTA+ training set of protein structures. Using subsets of amino acids that are plausibly assigned by SSNMR, we discovered that pairs of the residues Val, Ile, Thr, Ala and Leu (VITAL) emulate an ideal dataset where all residues are site specifically assigned. Scoring the models with a predicted VITAL site-specific dataset and calculating secondary structure with the Chemical Shift Index resulted in a Pearson correlation coefficient (-0.75) commensurate to the control (-0.77), where secondary structure was scored site specifically for all amino acids (ALL 20) using STRIDE. This method promises to accelerate structure procurement by SSNMR for proteins with unknown folds through guiding the selection of remotely homologous protein templates and assessing model quality.

    2011-05-01

    Full Text Available BACKGROUND. Literature about risk factors of alcohol use points at the association between alcohol use and parenting style. This study investigates the relationship between family structure of adolescents in Ukraine and their initiation of alcohol use with parenting style as a mediating variable.METHODS: Pooled data from the repeated cross-sectional nationally representative survey of classes in Ukrainian secondary schools with target group of all 15-16 year old students, held in 1999, 2003, and 2007, were used for this analysis. Complete data were available for 11019 participants. Main exposures were family structure (full, single parent and reconstructed and perceptions of the relationships with mother and father, rule-setting, control, and support provided by parents. Outcome measure was age when students started consuming alcohol.RESULTS: In bivariate analysis, children in reconstructed families had higher risk for initiating alcohol use at age of 13 or younger (odds ratio 1.37, confidence interval 1,15-1,63 compared to full families. In reconstructed families, adolescents were more likely to be dissatisfied with their relationships with mother compared to intact family structure (8.7% vs. 4.7% and dissatisfied with their relationships with father compared to intact family structure (19,8% vs. 9,1%. Parental support was lacking in higher proportion of reconstructed families, compared to intact family structure (20.7% vs. 15.1%. In the multivariate analysis, controlling for relationship with mother and father, support received from parents, and socio-demographic characteristics, the association between family structure and alcohol drinking initiation was attenuated.CONCLUSIONS: Children in reconstructed families have higher risk of early drinking initiation. This study also supports the hypothesis that dissatisfaction with relationships with parents and lack of support received from parents may mediate the association between family structure

  14. Identification of self-consistent modulons from bacterial microarray expression data with the help of structured regulon gene sets

    Permina, Elizaveta A.

    2013-01-01

    Identification of bacterial modulons from series of gene expression measurements on microarrays is a principal problem, especially relevant for inadequately studied but practically important species. Usage of a priori information on regulatory interactions helps to evaluate parameters for regulatory subnetwork inference. We suggest a procedure for modulon construction where a seed regulon is iteratively updated with genes having expression patterns similar to those for regulon member genes. A set of genes essential for a regulon is used to control modulon updating. Essential genes for a regulon were selected as a subset of regulon genes highly related by different measures to each other. Using Escherichia coli as a model, we studied how modulon identification depends on the data, including the microarray experiments set, the adopted relevance measure and the regulon itself. We have found that results of modulon identification are highly dependent on all parameters studied and thus the resulting modulon varies substantially depending on the identification procedure. Yet, modulons that were identified correctly displayed higher stability during iterations, which allows developing a procedure for reliable modulon identification in the case of less studied species where the known regulatory interactions are sparse.

  15. Exploring the Factor Structure of the Job Demands-Resources Measure With Patient Violence on Direct Care Workers in the Home Setting.

    Byon, Ha Do; Harrington, Donna; Storr, Carla L; Lipscomb, Jane

    2017-08-01

    Workplace violence research in health care settings using the Job Demands-Resources (JD-R) framework is hindered by the lack of comprehensive examination of the factor structure of the JD-R measure when it includes patient violence. Is patient violence a component of job demands or its own factor as an occupational outcome? Exploratory factor analysis and confirmatory factor analysis were conducted using a sample of direct care workers in the home setting (n = 961). The overall 2-construct JD-R structure persisted. Patient violence was not identified as a separate factor from job demands; rather, two demand factors emerged: violence/emotional and workload/physical demands. Although the three-factor model fits the data, the two-factor model with patient violence being a component of job demands is a parsimonious and effective measurement framework.

  16. Leakage current suppression with a combination of planarized gate and overlap/off-set structure in metal-induced laterally crystallized polycrystalline-silicon thin-film transistors

    Chae, Hee Jae; Seok, Ki Hwan; Lee, Sol Kyu; Joo, Seung Ki

    2018-04-01

    A novel inverted staggered metal-induced laterally crystallized (MILC) polycrystalline-silicon (poly-Si) thin-film transistors (TFTs) with a combination of a planarized gate and an overlap/off-set at the source-gate/drain-gate structure were fabricated and characterized. While the MILC process is advantageous for fabricating inverted staggered poly-Si TFTs, MILC TFTs reveal higher leakage current than TFTs crystallized by other processes due to their high trap density of Ni contamination. Due to this drawback, the planarized gate and overlap/off-set structure were applied to inverted staggered MILC TFTs. The proposed device shows drastic suppression of leakage current and pinning phenomenon by reducing the lateral electric field and the space-charge limited current from the gate to the drain.

  18. Setting the reference for the use of Chironomus sancticaroli (Diptera: Chironomidae as bioindicator: Ontogenetic pattern of larval head structures

    Débora Rebechi

    2012-04-01

    Full Text Available Species of Chironomidae are widely used as bioindicators of water quality, since their larvae undergo morphological deformities when in contact with sediment contaminated with chemicals. In this work we endeavored to study the morphology of head structures (antennae, mandible, mentum, pecten epipharyngis, ventromental plate and premandible throughout the development of the four larval instars of Chironomus sancticaroli Strixino & Strixino, 1981, which can be used in environmental impact analyses. Our results show that it is possible to differentiate among larval instars by doing a quantitative analysis on the number of striae on the ventromental plates. The six structures analyzed changed during larval ontogeny. These changes are part of the ontogeny of the immature stages not exposed to xenobiotics. We believe that the morphological pattern defined in this work can be used for comparisons with ontogenetic changes observed in field studies conducted in polluted environments.

  19. Leadership styles across hierarchical levels in nursing departments.

    Stordeur, S; Vandenberghe, C; D'hoore, W

    2000-01-01

    Some researchers have reported on the cascading effect of transformational leadership across hierarchical levels. One study examined this effect in nursing, but it was limited to a single hospital. To examine the cascading effect of leadership styles across hierarchical levels in a sample of nursing departments and to investigate the effect of hierarchical level on the relationships between leadership styles and various work outcomes. Based on a sample of eight hospitals, the cascading effect was tested using correlation analysis. The main sources of variation among leadership scores were determined with analyses of variance (ANOVA), and the interaction effect of hierarchical level and leadership styles on criterion variables was tested with moderated regression analysis. No support was found for a cascading effect of leadership across hierarchical levels. Rather, the variation of leadership scores was explained primarily by the organizational context. Transformational leadership had a stronger impact on criterion variables than transactional leadership. Interaction effects between leadership styles and hierarchical level were observed only for perceived unit effectiveness. The hospital's structure and culture are major determinants of leadership styles.

  12. Does Multiple Leadership Styles Mediated by Job Satisfaction Influence Better Business Performance? Perception of MNC Employees in Malaysia

    Kader Ali Noor Nasir

    2016-01-01

    Full Text Available One of the biggest challenges facing leaders today is the need to develop new business models that stress on effective leadership styles, employee job satisfaction and sustainability without sacrificing the financial and non-financial performance. The objective of this study is to examine the relationship between leadership styles and business performance of multinational companies operating in Malaysia mediated by job satisfaction. A quantitative study, using self-administered structured questionnaire, are issued using purposive sampling via direct distribution to 150 employees working in MNC. Analysis using Statistical Package for the Social Sciences (SPSS and Partial Least Square (PLS indicated that spiritual leadership style has the highest significant influence on job satisfaction, followed by authentic leadership style, transformational leadership style, and transactional leadership style. In addition, job satisfaction has a mediating effect on the relationship between each of the leadership styles, namely, transactional, transformational, authentic, and spiritual on business performance.

  13. An approach for maximizing the smallest eigenfrequency of structure vibration based on piecewise constant level set method

    Zhang, Zhengfang; Chen, Weifeng

    2018-05-01

    Maximization of the smallest eigenfrequency of the linearized elasticity system with area constraint is investigated. The elasticity system is extended into a large background domain, but the void is vacuum and not filled with ersatz material. The piecewise constant level set (PCLS) method is applied to present two regions, the original material region and the void region. A quadratic PCLS function is proposed to represent the characteristic function. Consequently, the functional derivative of the smallest eigenfrequency with respect to PCLS function takes nonzero value in the original material region and zero in the void region. A penalty gradient algorithm is proposed, which initializes the whole background domain with the original material and decreases the area of original material region till the area constraint is satisfied. 2D and 3D numerical examples are presented, illustrating the validity of the proposed algorithm.

  14. Exploring leadership styles for innovation: an exploratory factor analysis

    Wipulanusat Warit

    2017-03-01

    Full Text Available Leadership plays a vital role in building the process, structures, and climate for an organisation to become innovative and to motivate team expectations toward innovations. This study explores the leadership styles that engineers regard as significant for innovation in the public sector. Exploratory factor analysis (EFA was conducted to identify the principal leadership styles influencing innovation in the Australian Public Service (APS, using survey data extracted from the 2014 APS employee census comprising 3 125 engineering professionals in Commonwealth of Australia departments. EFA returned a two-factor structure explaining 77.6% of the variance of the leadership for innovation construct. In this study, the results from the EFA provided a clear estimation of the factor structure of the measures for leadership for innovation. From the results, the two factors extracted were transformational leadership and consideration leadership. In transformational leadership, a leader values organisational objectives, inspires subordinates to perform, and motivates followers beyond expected levels of work standards. Consideration leadership refers to the degree to which a leader shows concern and expressions of support for subordinates, takes care of their welfare, treats members as equals, and displays warmth and approachability. These findings highlight the role of leadership as the most critical predictor when considering the degree to which subordinates strive for creativity and innovation. Both transformational and consideration leadership styles are recommended to be incorporated into management training and development programs. This study also recommends that Commonwealth departments recruit supervisors who have both of these leadership styles before implementing innovative projects.

  15. The effects of structure anisotropy on lensing observables in an exact general relativistic setting for precision cosmology

    2014-03-01

    The study of relativistic, higher order, and nonlinear effects has become necessary in recent years in the pursuit of precision cosmology. We develop and apply here a framework to study gravitational lensing in exact models in general relativity that are not restricted to homogeneity and isotropy, and where full nonlinearity and relativistic effects are thus naturally included. We apply the framework to a specific, anisotropic galaxy cluster model which is based on a modified NFW halo density profile and described by the Szekeres metric. We examine the effects of increasing levels of anisotropy in the galaxy cluster on lensing observables like the convergence and shear for various lensing geometries, finding a strong nonlinear response in both the convergence and shear for rays passing through anisotropic regions of the cluster. Deviation from the expected values in a spherically symmetric structure are asymmetric with respect to path direction and thus will persist as a statistical effect when averaged over some ensemble of such clusters. The resulting relative difference in various geometries can be as large as approximately 2%, 8%, and 24% in the measure of convergence (1−κ) for levels of anisotropy of 5%, 10%, and 15%, respectively, as a fraction of total cluster mass. For the total magnitude of shear, the relative difference can grow near the center of the structure to be as large as 15%, 32%, and 44% for the same levels of anisotropy, averaged over the two extreme geometries. The convergence is impacted most strongly for rays which pass in directions along the axis of maximum dipole anisotropy in the structure, while the shear is most strongly impacted for rays which pass in directions orthogonal to this axis, as expected. The rich features found in the lensing signal due to anisotropic substructure are nearly entirely lost when one treats the cluster in the traditional FLRW lensing framework. These effects due to anisotropic structures are thus likely to

    The Gaussian-2 (G2) collection of atoms and molecules has been studied with Hartree endash Fock and correlated levels of theory, ranging from second-order perturbation theory to coupled cluster theory with noniterative inclusion of triple excitations. By exploiting the systematic convergence properties of the correlation consistent family of basis sets, complete basis set limits were estimated for a large number of the G2 energetic properties. Deviations with respect to experimentally derived energy differences corresponding to rigid molecules were obtained for 15 basis set/method combinations, as well as the estimated complete basis set limit. The latter values are necessary for establishing the intrinsic error for each method. In order to perform this analysis, the information generated in the present study was combined with the results of many previous benchmark studies in an electronic database, where it is available for use by other software tools. Such tools can assist users of electronic structure codes in making appropriate basis set and method choices that will increase the likelihood of achieving their accuracy goals without wasteful expenditures of computer resources. copyright 1998 American Institute of Physics

    South Africa faces a complex dual burden of chronic communicable and non-communicable diseases (NCDs). In response, the Integrated Chronic Disease Management (ICDM) model was initiated in primary health care (PHC) facilities in 2011 to leverage the HIV/ART programme to scale-up services for NCDs, achieve optimal patient health outcomes and improve the quality of medical care. However, little is known about the quality of care in the ICDM model. The objectives of this study were to: i) assess patients' and operational managers' satisfaction with the dimensions of ICDM services; and ii) evaluate the quality of care in the ICDM model using Avedis Donabedian's theory of relationships between structure (resources), process (clinical activities) and outcome (desired result of healthcare) constructs as a measure of quality of care. A cross-sectional study was conducted in 2013 in seven PHC facilities in the Bushbuckridge municipality of Mpumalanga Province, north-east South Africa - an area underpinned by a robust Health and Demographic Surveillance System (HDSS). The patient satisfaction questionnaire (PSQ-18), with measures reflecting structure/process/outcome (SPO) constructs, was adapted and administered to 435 chronic disease patients and the operational managers of all seven PHC facilities. The adapted questionnaire contained 17 dimensions of care, including eight dimensions identified as priority areas in the ICDM model - critical drugs, equipment, referral, defaulter tracing, prepacking of medicines, clinic appointments, waiting time, and coherence. A structural equation model was fit to operationalise Donabedian's theory, using unidirectional, mediation, and reciprocal pathways. The mediation pathway showed that the relationships between structure, process and outcome represented quality systems in the ICDM model. Structure correlated with process (0.40) and outcome (0.75). Given structure, process correlated with outcome (0.88). Of the 17 dimensions of care in

    Understanding and manipulating the interfacial mechanisms that control human digestion of food emulsions is a crucial step towards improved control of dietary intake. This article reports initial studies on the effects of the physiological conditions within the stomach on the properties of the film formed by the milk protein ( β -lactoglobulin) at the air-water interface. Atomic force microscopy (AFM), surface tension and surface rheology techniques were used to visualize and examine the effect of gastric conditions on the network structure. The effects of changes in temperature, pH and ionic strength on a pre-formed interfacial structure were characterized in order to simulate the actual digestion process. Changes in ionic strength had little effect on the surface properties. In isolation, acidification reduced both the dilatational and the surface shear modulus, mainly due to strong repulsive electrostatic interactions within the surface layer and raising the temperature to body temperature accelerated the rearrangements within the surface layer, resulting in a decrease of the dilatational response and an increase of surface pressure. Together pH and temperature display an unexpected synergism, independent of the ionic strength. Thus, exposure of a pre-formed interfacial β -lactoglobulin film to simulated gastric conditions reduced the surface dilatational modulus and surface shear moduli. This is attributed to a weakening of the surface network in which the surface rearrangements of the protein prior to exposure to gastric conditions might play a crucial role.

  20. On enclosure Norwegian style

    Full Text Available More than 200 years after the King sold one of the “King’s commons” to urban timber merchants, local people in some ways still behave as if the area is a kind of commons. The paper outlines the history of the transformation of the area from an 18th century King’s commons to a 21st century battleground for ideas about ancient access and use rights of community members facing rights claimed by a commercial forest owner within local consequences of national legislation. The discussion is focused on the right of common to hunt small game without dog in Follafoss private commons. The right was confirmed in a judgement of the Supreme Court in 1937 and in legislation on hunting in 1951. The Government’s proposal for new legislation on hunting in 1981 removed the right without saying a word about it, and it was never commented on in parliament during the legislative process. To explain what we observe it is suggested that a new layer of legislation on rights of common from 1857 and 1863 created a structural amnesia about private commons making it easy to remove them from legislation.
