    2001-04-01

    Self-selected individual course-grade weighting schemes allow students personal choice of course components in the general chemistry sequence at Coastal Carolina University. With the availability of a wide range of commercial and academically produced pedagogical resources, students can select materials that best suit their own learning styles, social situations, and motivation level. Our students use a signed contract to indicate their preferred grade-weighting schemes for determination of the course grade. In doing so, they choose from course components that include peer-led team learning (PLTL) in the Workshop Chemistry (WSC) model, computer-assisted instruction (CAI) using the ChemSkill Builder (CSB) software, a variety of in-class quizzes and group problem-solving exercises, written exams, and the final written exam. Minimum percentage values are required of all components except WSC and CSB, which have been completely optional graded course components at CCU since the summer of 1999. Comparison of student success in the course and content learning suggests that the improvements observed with introduction of a gamut of activities increase even more when the cafeteria-style grading is implemented.

    2018-01-01

    We propose an FDTD scheme based on Generalized Sheet Transition Conditions (GSTCs) for the simulation of polychromatic, nonlinear and space-time varying metasurfaces. This scheme consists in placing the metasurface at virtual nodal plane introduced between regular nodes of the staggered Yee grid and inserting fields determined by GSTCs in this plane in the standard FDTD algorithm. The resulting update equations are an elegant generalization of the standard FDTD equations. Indeed, in the limiting case of a null surface susceptibility ($\\chi_\\text{surf}=0$), they reduce to the latter, while in the next limiting case of a time-invariant metasurface $[\\chi_\\text{surf}\

    Surgical education is evolving under the dual pressures of an enlarging body of knowledge required during residency and mounting work-hour restrictions. Changes in surgical residency training need to be based on available educational models and research to ensure successful training of surgeons. Experiential learning theory, developed by David Kolb, demonstrates the importance of individual learning styles in improving learning. This study helps elucidate the way in which medical students, surgical residents, and surgical faculty learn. The Kolb Learning Style Inventory, which divides individual learning styles into Accommodating, Diverging, Converging, and Assimilating categories, was administered to the second year undergraduate medical students, general surgery resident body, and general surgery faculty at the University of Alberta. A total of 241 faculty, residents, and students were surveyed with an overall response rate of 73%. The predominant learning style of the medical students was assimilating and this was statistically significant (p learning style found in the residents and faculty. The predominant learning styles of the residents and faculty were convergent and accommodative, with no statistically significant differences between the residents and the faculty. We conclude that medical students have a significantly different learning style from general surgical trainees and general surgeons. This has important implications in the education of general surgery residents.

  13. Elastic Buckling Behaviour of General Multi-Layered Graphene Sheets

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Elastic buckling behaviour of multi-layered graphene sheets is rigorously investigated. Van der Waals forces are modelled, to a first order approximation, as linear physical springs which connect the nodes between the layers. Critical buckling loads and their associated modes are established and analyzed under different boundary conditions, aspect ratios and compressive loading ratios in the case of graphene sheets compressed in two perpendicular directions. Various practically possible loading configurations are examined and their effect on buckling characteristics is assessed. To model more accurately the buckling behaviour of multi-layered graphene sheets, a physically more representative and realistic mixed boundary support concept is proposed and applied. For the fundamental buckling mode under mixed boundary support, the layers with different boundary supports deform similarly but non-identically, leading to resultant van der Waals bonding forces between the layers which in turn affect critical buckling load. Results are compared with existing known solutions to illustrate the excellent numerical accuracy of the proposed modelling approach. The buckling characteristics of graphene sheets presented in this paper form a comprehensive and wholesome study which can be used as potential structural design guideline when graphene sheets are employed for nano-scale sensing and actuation applications such as nano-electro-mechanical systems.

    2012-07-01

    The question of whether certain anxiety disorders are especially related to a cognitive style characterized by an exaggerated perception of threat and appraisal of the future as excessively unpredictable (general anxiety-prone cognitive style) remains open. This study aimed to compare patients with generalized social anxiety disorder (SAD), generalized anxiety disorder (GAD), panic disorder with agoraphobia (PDA), and panic disorder without agoraphobia (PD) in terms of the levels of general anxiety-prone cognitive style when the severity of general distress and psychopathology is controlled for and to ascertain whether a co-occurring depressive disorder contributes substantially to the levels of this cognitive style. The Anxious Thoughts and Tendencies Scale, a measure of a general anxiety-prone cognitive style, and Symptom Checklist 90-Revised were administered to 204 patients with various anxiety disorders who attended an outpatient anxiety disorders clinic and were diagnosed based on a semistructured diagnostic interview. Patients with principal diagnoses of SAD and GAD had a more prominent general anxiety-prone cognitive style than patients with principal diagnoses of PD and PDA when the severity of general distress and psychopathology was controlled for. The presence or absence of a co-occurring depressive disorder had no bearing on this finding. The general cognitive component characterizes SAD and GAD more than it does PD and PDA, and a co-occurring depressive disorder does not affect this finding. These results have implications for distinguishing between various anxiety disorders. Copyright © 2012 Elsevier Inc. All rights reserved.

  19. Attributional style and the generality of learned helplessness.

    Alloy, L B; Peterson, C; Abramson, L Y; Seligman, M E

    1984-03-01

    According to the logic of the attribution reformulation of learned helplessness, the interaction of two factors influences whether helplessness experienced in one situation will transfer to a new situation. The model predicts that people who exhibit a style of attributing negative outcomes to global factors will show helplessness deficits in new situations that are either similar or dissimilar to the original situation in which they were helpless. In contrast, people who exhibit a style of attributing negative outcomes to only specific factors will show helplessness deficits in situations that are similar, but not dissimilar, to the original situation in which they were helpless. To test these predictions, we conducted two studies in which undergraduates with either a global or specific attributional style for negative outcomes were given one of three pretreatments in the typical helplessness triadic design: controllable bursts of noise, uncontrollable bursts of noise, or no noise. In Experiment 1, students were tested for helplessness deficits in a test situation similar to the pretreatment setting, whereas in Experiment 2, they were tested in a test situation dissimilar to the pretreatment setting. The findings were consistent with predictions of the reformulated helplessness theory.

    2017-10-01

    The association between individual differences in general attachment styles and psychopathy is currently unclear, despite the potential utility attachment theory could provide regarding the interpersonal characteristics of psychopathy and the etiology of this construct. The purpose of the current investigation was to clarify these associations. For this purpose, we analyzed responses from an Australian community sample (N = 249) and a U.S. community sample (N = 292) containing validated measures of psychopathy (Triarchic Psychopathy Measure and Expanded-Levenson Self-Report Psychopathy Scales [Australian sample only]) and general attachment styles (Experiences in Close Relationships-Revised-General Short Form and Attachment Styles Questionnaire) to replicate our findings across measures and samples. The psychopathy domain of boldness was consistently negatively associated with insecure attachment styles. Psychopathy's affective domain (meanness, callousness) was consistently associated with avoidant attachment, whereas its behavioral domain (disinhibition, antisocial) was consistently associated with insecure attachment styles, particularly anxious attachment. Our findings suggest that there are consistent associations between individual differences in general attachment styles and psychopathy in adult samples and provides preliminary support for further consideration of attachment theory in psychopathy research.

    Zhu, Ping; Wang, Zechen; Bonofiglo, Phillip

    2016-01-01

    A magnetic reconnection process in the generalized Harris sheet has been revealed to be intrinsically three-dimensional both geometrically and dynamically despite the spatial invariance of the original current sheet in the equilibrium current direction. The spatial distribution and structure of the quasi-separatrix layers, as well as their temporal emergence and evolution, indicate that the associated magnetic reconnection can only occur in a three-dimensional geometry which is irreducible to a two-dimensional reconnection process. Such a three-dimensional reconnection process is induced by the nonlinear development of an ideal MHD ballooning instability in the generalized Harris sheet, which is itself an intrinsically three-dimensional dynamic process.

    Flat, thin and lightweight lamps providing spatially uniform and dimmable illumination from active areas as large as 400 cm2 are being developed for general illumination and specialty applications. Comprising an array of low-temperature, nonequilibrium microplasmas driven by a dielectric barrier structure and operating at pressures of typically 400-700 Torr, these lamps have a packaged thickness luminance values beyond 26 000 cd m-2 with a luminous efficacy approaching 30 lm W-1. Third generation lamps, presently in limited production, offer a correlated colour temperature in the 3000-4100 K interval and a colour rendering index of 80. Current lamps employ Xe2 (λ ~ 172 nm) as the primary emitter photoexciting a mixture of phosphors, and the pressure dependence of the wavelength-integrated fluorescence from the electronically excited dimer has been investigated with a vacuum ultraviolet spectrometer. In contrast to other promising lighting technologies, the decline in luminous efficacy of microplasma lamps with increasing power delivered to the lamp is small. For a 6 × 6 inch2 (~225 cm2) lamp, efficacy falls luminance) is raised from 2000 cd m-2 to > 10 000 cd m-2.

    Explore the impact of general parenting style and specific food-related parenting practices on children's dietary habits. Cross-sectional study of sixth graders and their parents. Data were gathered (in 2003) in 69 of 100 randomly selected elementary schools in Belgium. All sixth graders (N = 1957) were invited to participate; 82.4% of their parents gave consent and completed questionnaires, resulting in 1614 parent-child pairs. Children's consumption of breakfast, fruit, vegetables, soft drinks, and sweets was assessed by self-administered food frequency questionnaires. Parents completed questionnaires on sociodemographic characteristics, general parenting styles (authoritarian, authoritative, indulgent, or neglecting) and specific food-related parenting practices (pressure, reward, encouragement through negotiation, catering on children's demands, permissiveness, avoiding negative modeling, and praise). Logistic regression analyses were performed, with general parenting style and specific food-related parenting practices as predictors and dietary habits as dependent variables, controlling for sociodemographic characteristics and children's weight status. General parenting style did not show any significant impact on dietary habits. In contrast, the food-related parenting practice "encouragement through negotiation" showed a significant positive impact, whereas "pressure," "catering on demand," and "permissiveness" were practices with an unhealthy impact. Nutrition education programs that guide parents in firm but not coercive food parenting skills are likely to have a positive impact upon children's dietary habits.

  9. Theoretical research on general Hosford yield function of cubic orthorhombic sheets metals

    Yang, Feng; Liu, Jun; Zhou, Hui

    2017-04-01

    Most of rolled sheet metals belong to orthorhombic aggregates of cubic crystallites. The texture coefficients, characterized by the preferred orientation of the crystallites, are important to set up the yield function. Although Hosford yield function is more suitable for describing both yield and plastic deformation of orthorhombic material than Hill, it suffers from the restriction that the three principal stresses have to be coaxial with the orthotropy of materials. Hence, this paper proposes a new Hosford yield function of cubic orthorhombic metal sheet at any stress states by introducing orientation-dependent functions. As well, the new yield function which covers 3 material parameters and 3 texture coefficients is more general than Hosford yield function. The plastic anisotropy of the q-value and yield stress under any stress states is obtained from the new yield function. This yield function lay a theoretical foundation for analyzing the mechanical properties of metal materials.

  11. The style of a stranger: Identification expertise generalizes to coarser level categories.

    Searston, Rachel A; Tangen, Jason M

    2017-08-01

    Experience identifying visual objects and categories improves generalization within the same class (e.g., discriminating bird species improves transfer to new bird species), but does such perceptual expertise transfer to coarser category judgments? We tested whether fingerprint experts, who spend their days comparing pairs of prints and judging whether they were left by the same finger or two different fingers, can generalize their finger discrimination expertise to people more broadly. That is, can these experts identify prints from Jones's right thumb and prints from Jones's right index finger as instances of the same "Jones" category? Novices and experts were both sensitive to the style of a stranger's prints; despite lower levels of confidence, experts were significantly more sensitive to this style than novices. This expert advantage persisted even when we reduced the number of exemplars provided. Our results demonstrate that perceptual expertise can be flexible to upwards shifts in the level of specificity, suggesting a dynamic memory retrieval process.

    2014-03-01

    In this paper, a general and efficient strategy has been developed to produce nitrogen-doped graphene sheets (NGs) based on hard and soft acids and bases (HSAB) theory. Under hydrothermal conditions, any salt with amphiprotic character have a strong tendency to hydrolysis, it is possible to provide reducing agent and nitrogen source simultaneously. It is worth noting that, NGs can be prepared under hydrothermal conditions by using some common ammonium salts with hard acid-soft base pairs as nitrogen-doping agents. The morphology, structure and composition of the as-prepared NGs were studied in detail. The results demonstrated that large amount of nitrogen was incorporated into the nanocarbon frameworks at the same time as the graphene oxide (GO) sheets were reduced. The electrochemical behavior of the synthesized NGs as supercapacitor electrodes was evaluated in a symmetric two-electrode cell configuration with 1M H2SO4 as the electrolytes. It was found that the nitrogen groups making the as-prepared NGs exhibited remarkably enhanced electrochemical performance when used as electrode materials in supercapacitors. The supercapacitor based on the NGs exhibited a high specific capacitance of 242 F g(-1) at a current density of 1 A g(-1), and remains a relatively high capacitance even at a high current density. This work will put forward to understand and optimize heteroatom-doped graphene in energy storage systems. Copyright © 2013 Elsevier Inc. All rights reserved.

    Emotional eating is the tendency to eat in response to negative emotions. Prior research has identified a relationship between parenting style and child emotional eating, but this has not been examined in clinical samples. Furthermore, the relationship between specific parenting practices (e.g., parent feeding practices) and child emotional eating has not yet been investigated. The current study examined relationships between child emotional eating and both general and specific parenting constructs as well as maternal symptoms of depression and binge eating among a treatment-seeking sample of overweight children. Participants included 106 mother-child dyads who attended a baseline assessment for enrollment in a behavioral intervention for overeating. Ages of children ranged from 8 to 12  years old. Mothers completed self-report measures of their child's emotional eating behavior, their own feeding practices, and symptoms of depression and binge eating. Children completed a self-report measure of their mothers' general parenting style. A stepwise regression analysis was conducted to identify the parent variable that was most strongly related to child emotional eating, controlling for child age and gender. Emotional feeding behavior (i.e., a tendency to offer food to soothe a child's negative emotions) was the parent factor most significantly related to child emotional eating. Findings suggest that emotional feeding practices in parents may be related to emotional eating in children. Treatment with overweight children who engage in emotional eating may be improved by targeting parent feeding practices. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2010-01-01

    Research on the mechanisms by which interparental conflict (IPC) affects child depression suggests that both parenting and children's conflict appraisals play important roles, but few studies have explored the role of general cognitive style or included both parenting and cognitions in the same design. Moreover, the effects of IPC on minority children are not well understood. In this longitudinal study, parenting was examined as a mediator of the relation between increasing IPC and change in depression. General cognitive style was included as a moderator. The combined influence of parenting and cognitions was also explored. A racially and ethnically diverse sample of 88 fifth and sixth graders from two urban schools reported their cognitive style, depressive symptoms, and perceptions of conflict and parenting at two time points separated by one year. Parental warmth/rejection mediated the relation between IPC and depression, and general cognitive style acted as a moderator. Parenting, cognitive style, and IPC did not significantly interact to predict change in depression over time. Findings indicate that both parenting and children's general cognitive style play a role in understanding the impact of increasing IPC on children's well-being.

  15. Evaluation of the Surface Representation of the Greenland Ice Sheet in a General Circulation Model

    2014-01-01

    Simulated surface conditions of the Goddard Earth Observing System model, version 5 (GEOS 5) atmospheric general circulation model (AGCM) are examined for the contemporary Greenland Ice Sheet (GrIS). A surface parameterization that explicitly models surface processes including snow compaction, meltwater percolation and refreezing, and surface albedo is found to remedy an erroneous deficit in the annual net surface energy flux and provide an adequate representation of surface mass balance (SMB) in an evaluation using simulations at two spatial resolutions. The simulated 1980-2008 GrIS SMB average is 24.7+/-4.5 cm yr(- 1) water-equivalent (w.e.) at.5 degree model grid spacing, and 18.2+/-3.3 cm yr(- 1) w.e. for 2 degree grid spacing. The spatial variability and seasonal cycle of the simulation compare favorably to recent studies using regional climate models, while results from 2 degree integrations reproduce the primary features of the SMB field. In comparison to historical glaciological observations, the coarser resolution model overestimates accumulation in the southern areas of the GrIS, while the overall SMB is underestimated. These changes relate to the sensitivity of accumulation and melt to the resolution of topography. The GEOS-5 SMB fields contrast with available corresponding atmospheric models simulations from the Coupled Model Intercomparison Project (CMIP5). It is found that only a few of the CMIP5 AGCMs examined provide significant summertime runoff, a dominant feature of the GrIS seasonal cycle. This is a condition that will need to be remedied if potential contributions to future eustatic change from polar ice sheets are to be examined with GCMs.

    Full Text Available Background & aim: Cardiovascular diseases are the most common cause of death and debilitation worldwide. Psychological factors compose more than 50 percent of the factors affecting heart diseases. Therefore, this research has been performed aiming to investigate the relationship between religiosity, humor styles and Type- D Personality with general health in the patients with heart disease. Methods: This study is descriptive of correlation type. The statistical population includes all patients with heart disease is the city of Yazd in the years 2015-2016. Two hundred and ten patients with heart disease were selected by available sampling method. Measurement tools are demographic characteristics questionnaire, Glark and Stark’s questionnaire with 24 items of religiosity, Martin’s 32-items questionnaire of humor, DS-14 Denollet’s short questionnaire, and General Health Questionnaire (GHQ-28. Using Pearson correlation coefficients and hierarchical regression analysis, the data was analyzed. Results: The results of data analysis showed that there is a positive significant relationship between the religiosity, affiliative humor style, self-enhancing humor style, and general health (P<0.01, and there is a negative significant relationship between Type- D Personality, aggressive humor style, self-accepting humor style and general health (P<0.01. Hierarchical multiple regression analysis showed that predictive variables explain 25% of the variance of general health. Conclusion: Considering that religiosity, humor styles, and Type- D Personality are among the important and affecting risk factors in the general health of patients with heart disease, by recognizing such factors, the individuals predisposed to this disease can be identified for preventative measures and helping in treatment. The change in the lifestyle of such patients can also reduce the severity of disease and its effects, and make the impacts of medical treatments more reliable.

    To identify conflict mode choices of head nurses in general hospitals and examine the relationship between leadership style, choice of strategy in handling conflicts and demographic characteristics. Nurse managers deal with conflicts daily. The choice of conflict management mode is associated with managerial effectiveness. The ability to creatively manage conflict situations, towards constructive outcomes is becoming a standard requirement. Head nurses (N = 60) in five general hospitals in central Israel were surveyed, using a 3-part questionnaire: The Thomas-Kilmann Conflict Mode Instrument, the Multi-factor Leadership Questionnaire, Form 5X-Short (MLQ 5X) and demographic data. Head nurses perceive themselves significantly more as transformational leaders than as transactional leaders. Compromise was found to be the most commonly used conflict management strategy. Approximately half of the nurses surveyed used only one mode in conflict management. Transformational leadership significantly affected the conflict strategy chosen. Head nurses tend to choose a conflict-handling mode which is concerned a form of a Lose-Lose approach. Preparation in conflict management should start from undergraduate education.

    2016-01-01

    Using the multiple-scale homogenization method, we derive generalized sheet transition conditions (GSTCs) for electromagnetic fields at the surface of a metafilm. The scatterers that compose the metafilm are of arbitrary shape and are embedded between two different magneto-dielectric media. The parameters in these boundary conditions are interpreted as effective electric and magnetic surface susceptibilities, which themselves are related to the geometry of the scatterers that constitute the metafilm.

  1. General and food-selection specific parenting style in relation to the healthfulness of parent-child choices while grocery shopping.

    Past research has demonstrated that parenting style is related to children's health and eating patterns, and that parenting can vary across time and context. However, there is little evidence about similarities and differences between general, self-reported parenting style and observed parenting during grocery shopping. The goals of this study were to investigate links between general parenting style, parental warmth and limit setting (important dimensions of parenting style) during grocery shopping, and the healthfulness of foods chosen. Participants were 153 parent (88 mothers) - child (6-9 years old) dyads. Dyads were brought to a laboratory set up like a grocery store aisle and asked to choose two items from each of three categories (cookies/crackers, cereals, chips/snacks). Parents were observed in terms of warmth, responsiveness, autonomy granting, and limit setting; children were observed in terms of resistance and negotiation. Parents reported behaviors related to general parenting. Regression analyses were used to test study hypotheses. Observed parental limit setting was related to general parenting style; observed warmth was not. Observed limit setting (but not observed warmth or self-reported parenting style) was related to the healthfulness of food choices. Limit setting appears to be the dimension of parenting style that is expressed during grocery shopping, and that promotes healthier food choices. Implications are discussed regarding consistencies in parenting style across situations as well as contributions of parenting style to the development of children's healthy eating.

    Objective: To examine relationships between parenting styles and practices and child moderate-to-vigorous physical activity (MVPA) and screen time. Methods: Participants were children (6.9 ± 1.8 years) with a body mass index in the 70–95th percentile and their parents (421 dyads). Parent-completed questionnaires assessed parental support for child physical activity (PA), parenting styles and child screen time. Children wore accelerometers to assess MVPA. Results: Parenting style did not predict MVPA, but support for PA did (positive association). The association between support and MVPA, moreover, varied as a function of permissive parenting. For parents high in permissiveness, the association was positive (greater support was related to greater MVPA and therefore protective). For parents low in permissiveness, the association was neutral; support did not matter. Authoritarian and permissive parenting styles were both associated with greater screen time. Conclusions: Parenting practices and styles should be considered jointly, offering implications for tailored interventions.

    Studies of primary and tertiary care patients suggest that maladaptive coping styles contribute to the pathogenesis and maintenance of chronic fatigue syndrome (CFS). We assessed coping styles in persons with unexplained fatigue and nonfatigued controls in a population-based study. We enrolled 43 subjects meeting the 1994 Research Case Definition of CFS, matching them with 61 subjects with chronic unexplained fatigue who did not meet criteria for CFS [we term them insufficient symptoms or fatigue (ISF)] and 60 non-ill (NI) controls. Coping styles and clinical features of CFS were assessed using standard rating scales. Subjects with CFS and ISF reported significantly more escape-avoiding behavior than NI controls. There were no differences between the CFS and ISF subjects. Among participants with CFS, escape-avoiding behavior was associated with fatigue severity, pain, and disability. We demonstrate significantly higher reporting of maladaptive coping in a population-based sample of people with CFS and other unexplained fatiguing illnesses defined by reproducible standardized clinical empirical means in comparison to NI controls.

    To examine cross-sectional and longitudinal (one-year follow-up) associations of parental feeding styles with child snacking behaviour and weight in the context of general parenting, taking into account the multidimensionality of the controlling feeding style. Linear regression analyses were performed. Parents completed a questionnaire to measure five feeding style dimensions (Instrumental Feeding, Emotional Feeding, Encouragement, Overt Control and Covert Control) and children's fruit, energy-dense snack and sugar-sweetened beverage (SSB) intakes. Children's height and weight were measured to calculate their BMI Z-scores. Moderation by parenting style was tested by adding interaction terms to the regression analyses. Observational study in the Netherlands. Parent-child dyads (n 1275) participating in the INPACT (IVO Nutrition and Physical Activity Child cohorT) study; children were (on average) 9 years of age. Instrumental Feeding and Emotional Feeding were negatively related to child fruit intake one year later and positively to (changes in) child energy-dense snack intake. Encouragement was negatively related to child energy-dense snacking and SSB intake one year later. Overt Control was cross-sectionally and prospectively related to (changes in) child energy-dense snacking and SSB intake in a negative direction. Covert Control showed similar associations with child energy-dense snacking and SSB intake as Overt Control. Although Covert Control was also positively related to child fruit intake and (changes in) child BMI Z-score, bootstrapping analyses revealed only a differential effect of Overt Control and Covert Control on child BMI Z-score one year later, with Covert Control displaying a stronger, positive association. Moderation analyses showed that some significant associations between parental feeding styles and outcome measures were dependent on the degree of psychological control and behavioural control. Instrumental Feeding and Emotional Feeding may have

    Among 139 students (mean age 21.8, SD=3.5), use of Schmeck's Deep Processing learning style (looking for conceptual understanding) on academic materials correlated modestly with its use on religious materials. The same was true for Elaborative Processing (looking for associations and applications). Both Deep and Elaborative Processing of academic materials correlated with better Analytical Skills. Only Elaborative Processing of religious materials correlated with Religiousness. Religiousness correlated with poorer Analytical Skills on academic materials and with a more Concrete Divine Concept; however, specific religious affiliation made a difference. Our understanding of the role of contents of materials and characteristics of learners on the types of learning strategies used and competence with cognitive skills is still very limited.

    To investigate whether fruit and vegetable (F&V) intake in 11-year-olds, and social-environmental correlates of F&V intake such as parental modelling and encouragement, family food rules and home availability, differ according to general parenting styles in Belgium, The Netherlands, Portugal and Spain. Cross-sectional study. Primary schools in four countries. Pupils and one of their parents completed questionnaires to measure F&V intake, related social-environmental correlates and general parenting styles. The sample size was 4555 (49.3 % boys); 1180 for Belgium, 883 for The Netherlands, 1515 for Portugal and 977 for Spain. Parenting styles were divided into authoritative, authoritarian, indulgent and neglectful. No differences were found in F&V intake across parenting styles and only very few significant differences in social-environmental correlates. The authoritarian (more parental encouragement and more demands to eat fruit) and the authoritative (more availability of fruit and vegetables) parenting styles resulted in more favourable correlates. Despite earlier studies suggesting that general parenting styles are associated with health behaviours in children, the present study suggests that this association is weak to non-existent for F&V intakes in four different European countries.

    2015-08-01

    One of the long-standing debates in the study of adult attachment is whether individual differences are best captured using categorical or continuous models. Although early research suggested that continuous models might be most appropriate, we revisit this issue here because (a) categorical models continue to be widely used in the empirical literature, (b) contemporary models of individual differences raise new questions about the structure of attachment, and (c) methods for addressing the types versus dimensions question have become more sophisticated over time. Analyses based on 2 samples indicate that individual differences appear more consistent with a dimensional rather than a categorical model. This was true with respect to general attachment representations and attachment in specific relationship contexts (e.g., attachment with parents and peers). These findings indicate that dimensional models of attachment style may be better suited for conceptualizing and measuring individual differences across multiple levels of analysis.

    Gastrointestinal symptoms are quite common among the general population, but different survey methods show different epidemiology, and the effect of psychosocial and behavioral factors on the symptoms have been studied mainly by the subgroup The aims of this studies are; 1: to clarify the difference of the survey methods on the epidemiology of FGID symptoms, 2: correlation with psycho-behavioral background in symptomatic subjects. Questionnaires focused on GI symptoms and psycho-behavioral background were generated. Questionnaires were sent via e-mail and postal mail to the members of the registered panel. A total of 2125 and 11,020 responses were recovered from electronic survey and postal survey. Significant difference in the prevalence of GI symptoms, 47% in electronic survey and 25% in postal survey, were observed. Despite the difference in the prevalence, the proportions of symptom subtypes and the patterns of the overlaps were similar in the two methods. In the analysis of the effect of psycho-behavioral factors, this study showed that those who have higher level of psycho-behavioral problem had higher prevalence of GERD, FD and IBS symptoms. Those who have impairment in the wellness sensation such as good eating, good bowel movement and good sleep showed higher prevalence of each symptom. Those who prefer unhealthier food have higher prevalence of GI symptoms. These data suggest that psycho-behavioral conditions may affect the development of functional GI symptoms regardless of the subtypes of GI symptoms, and may explain the high proportion of overlap in the subtypes. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

    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.

    In developed countries, systolic blood pressure is known to increase with age. Metabolic risks may generally worse with increasing age. But this trend may be modified by environmental factors which are different between gender and generation. The aim of this study was to examine the relationship between age and gender-related difference in cardio-metabolic risks and life style factors in the Japanese general population. We studied 3628 inhabitants of Watari (mean age 63.9 yrs, 42.5% men), Miyagi prefecture, who participated in a health check-up in 2009. Anthropometry, sitting blood pressures, fasting blood samples were examined. Unhealthy dietary behaviors (night meal, late dinner, fast eating, skipping breakfast, smoking, heavy drinking, lack of regular exercise) were evaluated by standard questionnaire. Presence or absence of each behavior was scored 0 or 1 and total score was calculated as healthy life style score (range 0 to 7, higher the better). Gender difference in age-related changes in blood pressures, BMI, lipid and glucose metabolism were examined by two way ANOVA. Systolic blood pressure was continuously increased from age 30 s to 70 s in both genders. Systolic blood pressure was significantly higher in men than in women in age 30 s (122.0 ± 13.9 vs. 113.3 ± 12.8 mmHg, p < 0.001) but the difference decreased with an increase in age. Similar gender interaction was observed for diastolic blood pressure, BMI, triglyceride and high density lipoprotein (all p < 0.001) but was not for HbA1c. The healthy life style score was lowest in men age 30 s (5.1 ± 1.5) and it increased with an increase in age. Women demonstrated significantly higher healthy life style score than men in all generations. The gender difference in the score was largest in age 30 s and decreased with an increase in age. Cardio-metabolic risks are worse in men than in women in young generation but this gender difference diminishes with age. The gender

    Fundi, Shaaban Kitindi

    This study explored the matching hypothesis by examining the effect of matching students' learning style preferences with teachers' instructional strategies on students' academic performance and lesson enjoyment in a high school general chemistry course. To achieve the study aims, the researcher utilized a single-participant study design with a baseline phase and four treatment phases. Determination of students' learning style preferences involved using the Visual, Audial, Read/Write, and Kinesthetic (VARK) Learning Style Inventory. During the one-week baseline phase, students received instruction using regular instructional strategies, followed by four treatment phases: visual intervention, audial intervention, read/write intervention, and a kinesthetic intervention. Each intervention phase lasted one week. During each phase, the researcher measured academic achievement using three teacher-created quiz scores. Student enjoyment was measured using the Test of Science-Related Attitudes (TOSRA). A total of 14 students completed the VARK Questionnaire. Of these, eight students (2 boys and 6 girls) exhibited a multimodal learning style were subsequently excluded from study participation. An additional student was excluded due to excessive absenteeism, leaving five students who completed all phases of the study. Results indicated that matching students' learning style preferences with teachers' instructional strategies did not improve students' academic performance as measured by teacher-created quizzes. However, weekly switching of the instructional strategies did improve student enjoyment of chemistry lessons. Student enjoyment increased for all participants in all intervention phases regardless of whether or not instruction matched students' learning style preferences compared to baseline phase. The results of this study do not support the matching hypothesis. The students in this study, preferred to learn with multiple teaching strategies. Alternating instructional

    Previous research has suggested that extraordinary adverse experiences during childhood, such as abuse, are possible risk factors for the development of chronic pain. However, the relationship between the perceived parental bonding style during childhood and chronic pain has been much less studied. In this cross-sectional study, 760 community-dwelling Japanese adults were asked if they had pain that had been present for six months or more. They completed the Parental Bonding Instrument (PBI), a self-administrated questionnaire designed to assess perceived parental bonding, and the Patient Health Questionnaire-9 to assess current depressive symptoms. The PBI consists of care and overprotection subscales that are analyzed by assigning the parental bonding style to one of four quadrants: Optimal bonding (high care/low overprotection), neglectful parenting (low care/low overprotection), affectionate constraint (high care/high overprotection), and affectionless control (low care/high overprotection). Logistic regression analysis was done to estimate the contribution of the parental bonding style to the risk of chronic pain, controlling for demographic variables. Compared to the optimal bonding group, the odds ratios (ORs) for having chronic pain were significantly higher in the affectionless control group for paternal bonding (OR: 2.21, 95% CI: 1.50-3.27) and for maternal bonding (OR: 1.60, 95% CI: 1.09-2.36). After adjusting for depression, significance remained only for paternal bonding. The results demonstrate that the parental bonding style during childhood is associated with the prevalence of chronic pain in adults in the general population and that the association is more robust for paternal bonding than for maternal bonding.

One-hundred-and-eighteen overweight and obese children (10.40 ± 1.35 years; 53% female; 52% Caucasian; BMI-z: 2.06 ± 0.39) and their parents (42.42 ± 6.20 years; 91% female; 70% Caucasian; BMI: 31.74 ± 6.96 kg/m(2) ) were seen at a baseline assessment visit for a behavioral intervention that targeted overeating. The Eating Disorder Examination, adapted for children (ChEDE) was administered to assess for LOC eating. Parents completed the Parental Feeding Styles Questionnaire (PFSQ) and the Child Feeding Questionnaire (CFQ) to assess parent feeding styles and behaviors. Children also completed a self-report measure of general parenting (Child Report of Parent Behavior Inventory, CRPBI-30). Forty-three children (36.40%) reported at least one LOC eating episode in the month prior to assessment. Parents who reported greater restriction and higher levels of pressure to eat were more likely to have children that reported LOC eating (ps Parents who utilized more instrumental feeding and prompting/encouragement to eat techniques were less likely to have children that reported LOC eating (ps parenting behaviors were unrelated to child LOC eating (ps > 0.05). Parent feeding styles and behaviors appear to be differentially and uniquely related to LOC eating in treatment-seeking overweight and obese children. Future research is needed to determine if implementing interventions that target parent feeding behaviors may reduce LOC eating, prevent full-syndrome eating disorders, and reduce weight gain in youth. © 2015 Wiley Periodicals, Inc.

    Background: Evidence should drive public health initiatives to better address the most important health issues. Chronic diseases represent the main burden of healthcare expenditure in Western countries and are determined by risk factors related to behaviour. Population-based surveys should lead to well informed decision making in this field.

    Methods: A cross-sectional survey was carried out among the general population aged between 18 and 69 in the district of Monza-Brianza in Northern Italy through phone interviews. A validated questionnaire investigating health-related lifestyles and behaviours was used. The questionnaire was divided into the following parts: general health status, physical activity, smoking habit, nutrition, alcohol consumption, driving safety, cardiovascular risk, cancer screening, mental health, domestic safety and socio-economic status.

    Results: In total, 308 interviews were carried out (response rate=76%. Almost 40% reported a body mass index >25, 64.9% had high school or university degrees, 60.4% worked full-time, 26.2% were assessed as physically inactive, and 13.3% were on a weight –loss diet. In addition, 19.7% had an “at risk” alcohol consumption , especially among younger age groups. Symptoms of depression were identified in 4.9% of the study subjects, particularly in women.

    Conclusions: Age, body mass index, education, and occupation were significantly associated with the likelihood of reporting poor health status. Young subjects were more likely to be smokers and drinkers at risk. Psychological health and appropriate prescription of anti-cholesterol and anti-hypertensive drugs areì areas deserving further investigations. Nutrition, physical activity, driving safety and youth health, especially concerning drinking

    To determine if surgical residents share a preferred learning style as measured by Kolb's Learning Style Inventory (LSI) and if a relationship exists between resident learning style and achievement as measured by a standardized examination (AME). Also, core faculty learning styles were assessed to determine if faculty and residents share a preferred learning style. Kolb's LSI, Version 3, was administered to 16 surgical residents and the residency program's core faculty of 6 attending physicians. To measure academic achievement, the American Medical Education (AME) examination was administered to residents. The Hospital of Saint Raphael, General Surgery Residency Program, New Haven, Connecticut. Both instruments were administered to residents during protected core curriculum time. Core faculty were administered the LSI on an individual basis. Surgical residents of the Hospital of Saint Raphael's General Surgery Residency Program and 6 core faculty members Analysis of resident learning style preference revealed Converging as the most commonly occurring style for residents (7) followed by Accommodating (5), Assimilating (3), and Diverging (1). The predominant learning style for core faculty was also Converging (4) with 2 Divergers. The average score for the Convergers on the AME was 62.6 compared with 42 for the next most frequently occurring learning style, Accommodators. In this surgical residency program, a preferred learning style for residents seems to exist (Converging), which confirms what previous studies have found. Additionally, residents with this learning style attained a higher average achievement score as measured by the AME. Also, core faculty share the same preferential learning style as this subset of residents.

  2. Revisiting the concept of 'style match'.

    2013-06-01

    Intellectual style, an encompassing term for such constructs as learning style, teaching style, teaching approach, and thinking style, refers to one's preferred way of processing information. For the past several decades, whether or not there is a need for a match between teachers' teaching styles and students' learning styles has been the focal point for debate among researchers, educators, and the general public. The preliminary objective of this research was to investigate the psychometric properties of the Preferred Teaching Approach Inventory (PTAI). The research's primary objective was to re-examine the concept of 'style match' through testing the predictive power of students' thinking styles for their preferred teaching approaches. Data were collected from two samples of university students, one each from Shanghai, mainland China (N = 236), and Hong Kong (N = 123). Participants provided the required demographic information and responded to two self-report inventories: the Thinking Styles Inventory - Revised II and the PTAI. Acceptable reliability and good validity were found for the PTAI. All of the eight multiple regressions indicated that students' thinking styles significantly contributed to their preferences for teachers' teaching approaches. These contributions varied by gender among the Shanghai students and by academic discipline among the Hong Kong students. Students, especially Shanghai female students and Hong Kong natural science students, are open to teaching approaches that do not precisely match their thinking styles. The concept of 'style match' requires new understanding. Findings have implications for research and education. © 2013 The British Psychological Society.

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.

    Relevant to the study of epileptogenesis is learning processing, given the pivotal role that neuroplasticity assumes in both mechanisms. Recently, evoked potential analyses showed a link between analytic cognitive style and altered neural excitability in both migraine and healthy subjects, regardless of cognitive impairment or psychological disorders. In this study we evaluated analytic/global and visual/auditory perceptual dimensions of cognitive style in patients with epilepsy. Twenty-five cryptogenic temporal lobe epilepsy (TLE) patients matched with 25 idiopathic generalized epilepsy (IGE) sufferers and 25 healthy volunteers were recruited and participated in three cognitive style tests: "Sternberg-Wagner Self-Assessment Inventory", the C. Cornoldi test series called AMOS, and the Mariani Learning style Questionnaire. Our results demonstrate a significant association between analytic cognitive style and both IGE and TLE and respectively a predominant auditory and visual analytic style (ANOVA: p values style and its neurophysiological correlates in epilepsy.

    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.

  10. Ice sheet hydrology - a review

    This report summarizes the theoretical knowledge on water flow in and beneath glaciers and ice sheets and how these theories are applied in models to simulate the hydrology of ice sheets. The purpose is to present the state of knowledge and, perhaps more importantly, identify the gaps in our understanding of ice sheet hydrology. Many general concepts in hydrology and hydraulics are applicable to water flow in glaciers. However, the unique situation of having the liquid phase flowing in conduits of the solid phase of the same material, water, is not a commonly occurring phenomena. This situation means that the heat exchange between the phases and the resulting phase changes also have to be accounted for in the analysis. The fact that the solidus in the pressure-temperature dependent phase diagram of water has a negative slope provides further complications. Ice can thus melt or freeze from both temperature and pressure variations or variations in both. In order to provide details of the current understanding of water flow in conjunction with deforming ice and to provide understanding for the development of ideas and models, emphasis has been put on the mathematical treatments, which are reproduced in detail. Qualitative results corroborating theory or, perhaps more often, questioning the simplifications made in theory, are also given. The overarching problem with our knowledge of glacier hydrology is the gap between the local theories of processes and the general flow of water in glaciers and ice sheets. Water is often channelized in non-stationary conduits through the ice, features which due to their minute size relative to the size of glaciers and ice sheets are difficult to incorporate in spatially larger models. Since the dynamic response of ice sheets to global warming is becoming a key issue in, e.g. sea-level change studies, the problems of the coupling between the hydrology of an ice sheet and its dynamics is steadily gaining interest. New work is emerging

  11. Parenting styles, feeding styles, and their influence on child obesogenic behaviors and body weight. A review.

    Vollmer, Rachel L; Mobley, Amy R

    2013-12-01

    With recommendations to include parents as targets for childhood obesity interventions, there is a need to review the relationship of general parenting influences on childhood obesity. Therefore, the aim of this review is to examine the existing literature regarding the influence of parenting style and/or feeding styles on childhood obesogenic behaviors and body weight. Research articles related to parenting style (n=40) and parental feeding style (n=11) were identified and reviewed. An authoritative style appears to be the most protective parenting and feeding style while the indulgent feeding style is consistently associated with negative health outcomes. Overall, results for parenting style studies are inconsistent due to differences in conceptualization and measurement, while the results for feeding styles are much more cohesive. The literature is lacking in the ability to describe the interplay between parenting and feeding styles and child obesity risk. Recommendations for future research and interventions are discussed in regards to feeding style and influences on childhood obesity. Copyright © 2013 Elsevier Ltd. All rights reserved.

  12. The chemists' style of thinking.

    Bensaude-Vincent, Bernadette

    2009-12-01

    This paper discusses the relevance of the notion of "styles of scientific thinking" introduced by Alistair Crombie and revisited by Ian Hacking, for understanding how chemistry shaped its identity. Although neither Crombie nor Hacking applied this notion to individual disciplines, it seems appropriate to use it in the case of chemistry because it helps to address a puzzling issue: how did chemists manage to shape an identity of their own, despite shifting territories and theoretical transformations? Following a presentation of the notion of style, I will argue that the stable identity of chemistry is rooted in laboratory practices, which determined the specific questions that chemists put to nature as well as the answers to their questions. The "chemical style of thinking" is characterized by (i) a specific way of knowing through making, (ii) the concern with individual materials rather than matter in general and (iii) a specific commitment to nature.

    Da Frè Monica

    2007-05-01

    Full Text Available Abstract Background The growing popularity of CAM among the public is coupled with an ongoing debate on its effectiveness, safety, and its implications on the reimbursement system. This issue is critically important for GPs, who have a "gatekeeping" role with respect to health care expenditure. GPs must be aware of medications' uses, limitations and possible adverse effects. Our objective was to explore GPs' knowledge of CAM and patterns of recommendation and practice, as well as the relationship between such patterns and GPs' life-styles. Methods A cross-sectional study was conducted in Tuscany, a region of central Italy. One hundred percent female GPs (498 and a 60% random sample of male GPs (1310 practising in the region were contacted through a self-administered postal questionnaire followed by a postal reminder and telephone interview. Results Overall response rate was 82.1%. Most respondents (58% recommended CAM but a far smaller fraction (13% practised it; yet 36% of CAM practitioners had no certificated training. Being female, younger age, practising in larger communities, having had some training in CAM as well as following a vegetarian or macrobiotic diet and doing physical activity were independent predictors of CAM recommendation and practice. However, 42% of GPs did not recommend CAM to patients mostly because of the insufficient evidence of its effectiveness. Conclusion CAM knowledge among GPs is not as widespread as the public demand seems to require, and the scarce evidence of CAM effectiveness hinders its professional use among a considerable number of GPs. Sound research on CAM effectiveness is needed to guide physicians' behaviour, to safeguard patients' safety, and to assist policy-makers in planning regulations for CAM usage.

  15. Style in Music

    Science.gov (United States)

    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.

Owing to the incomplete deglaciation the isostatic signal left by the LGM ice sheet...... in Greenland is not simple, but composed of several domes with high uplift separated by swales with low uplift. This pattern, which reflects both unloading after LGM and reloading during Neoglacial ice sheet growth, shows that different sectors of the ice sheet responded differently to Holocene warming...

    In developing countries, suburban population is increasing. However, their health issues are rarely considered in studies. Socioeconomic and environmental factors in their neighbourhood can affect their lifestyle and health. Compared to men, women have fewer social resources and are more susceptible to an unfavourable environment, in general. To investigate the association between lifestyle and general health status in suburban women. This correlation, cross-sectional study assessed the lifestyle and general health, among suburban women living in Shirabad neighbourhood, Zahedan, Iran. Randomized one stage cluster sampling was used and 132 people participated in the study. Lifestyle Questionnaire (LSQ) and General Health Questionnaire-28 (GHQ-28) were used for data collection. For data analysis, descriptive statistical methods, Pearson's correlation coefficient and multivariate regression analysis were performed. Mean score of LSQ was 100.23±20.45 and mean GHQ-28 score was 28.46±16.41. There was a significant negative relationship between lifestyle and GHQ-28 total score (r=-0.619, p=0.01). Multivariate regression analysis showed that among predictor variables, education, sports and fitness and psychological health components had a significant relationship with GHQ-28 (plifestyle and health status. Also, it showed a significant relationship between education, sports and fitness and psychological health components and health. As a result, implementation of programs to modify lifestyle especially in the field of sports and improving the educational level could be useful in promoting women's health.

    A thin sheet of nematic elastomer attains 3D configurations depending on the nematic director field upon heating. In this Letter, we describe the intrinsic geometry of such a sheet and derive an expression for the metric induced by general nematic director fields. Furthermore, we investigate the reverse problem of constructing a director field that induces a specified 2D geometry. We provide an explicit recipe for how to construct any surface of revolution using this method. Finally, we show that by inscribing a director field gradient across the sheet's thickness, one can obtain a nontrivial hyperbolic reference curvature tensor, which together with the prescription of a reference metric allows dictation of actual configurations for a thin sheet of nematic elastomer.

This study explored the associations between resilience, infertility-related and general distress, and coping behaviors in forty women from nine fertility clinics throughout the United States. Participants completed the Connor-Davidson Resilience Scale (CD-RISC), Symptom Checklist-90 (SCL-90), Beck-Depression Inventory-II (BDI-II), Fertility Problem Inventory (FPI), and Ways of Coping Questionnaire (WCQ). Women with fertility problems evidenced significantly lower resilience scores than published norms. This study established evidence for the reliability and convergent validity of the CD-RISC with infertile populations. However, similar to other studies using this instrument, the factor structure reported by Connor and Davidson [Connor KM, Davidson JR. Development of a new resilience scale: the Connor-Davidson resilience scale (CD-RISC). Depression and Anxiety 2003;18:76-82] was not well supported. Resilience was negatively associated with infertility-specific and general distress. Engagement in action-focused coping skills was positively correlated with resilience. Implications for enhancing resilience with this population as are discussed. Copyright 2009 Elsevier Ltd. All rights reserved.

    The DARPA HiFIVE project uses a pulsed electron sheet beam gun to power a traveling wave tube amplifier operating at 220 GHz. Presented is a method for characterizing the high current density 0.1 mm by 1 mm sheet electron beam. A tungsten tipped probe was scanned through the cross section of the sheet electron beam inside of a vacuum vessel. The probe was controlled with sub-micron precision using stepper motors and LabView computer control while boxcar averaging hardware sampled the pulsed beam. Matlab algorithms were used to interpret the data, calculate beam dimensions and current density, and create 2-dimensional cross section images. Full characterization of two separate HiFIVE sheet electron guns was accomplished and is also presented.

    2015-09-01

    The learning style preferences of general surgery residents have been previously reported; there is evidence that residents who prefer read/write learning styles perform better on the American Board of Surgery In-Training Examination (ABSITE). However, little is known regarding the learning style preferences of applicants to general surgery residency and their impact on educational outcomes. In this study, the preferred learning styles of surgical residency applicants were determined. We hypothesized that applicant rank data are associated with specific learning style preferences. The Fleming VARK learning styles inventory was offered to all general surgery residency applicants that were interviewed at a university hospital-based program. The VARK model categorizes learners as visual (V), aural (A), read/write (R), kinesthetic (K), or multimodal (MM). Responses on the inventory were scored to determine the preferred learning style for each applicant. Applicant data, including United States Medical Licensing Examination (USMLE) scores, class rank, interview score, and overall final applicant ranking, were examined for association with preferred learning styles. Sixty-seven applicants were interviewed. Five applicants were excluded due to not completing the VARK inventory or having incomplete applicant data. The remaining 62 applicants (92%) were included for analysis. Most applicants (57%) had a multimodal preference. Sixty-nine percent of all applicants had some degree of preference for kinesthetic learning. There were statistically significant differences between applicants of different learning styles in terms of USMLE step 1 scores (P = 0.001) and USMLE step 2 clinical knowledge scores (P = 0.01), but not for class ranks (P = 0.27), interview scores (P = 0.20), or final ranks (P = 0.14). Multiple comparison analysis demonstrated that applicants with aural preferences had higher USMLE 1 scores (233.2) than those with kinesthetic (211.8, P = 0.005) or multimodal

  18. Ice sheet hydrology from observations

    Energy Technology Data Exchange (ETDEWEB)

    Jansson, Peter (Dept. of Physical Geography and Quaternary Geology, Stockholm Univ-, Stockholm (Sweden))

    2010-11-15

    The hydrological systems of ice sheets are complex. Our view of the system is split, largely due to the complexity of observing the systems. Our basic knowledge of processes have been obtained from smaller glaciers and although applicable in general to the larger scales of the ice sheets, ice sheets contain features not observable on smaller glaciers due to their size. The generation of water on the ice sheet surface is well understood and can be satisfactorily modeled. The routing of water from the surface down through the ice is not complicated in terms of procat has been problematic is the way in which the couplings between surface and bed has been accomplished through a kilometer of cold ice, but with the studies on crack propagation and lake drainage on Greenland we are beginning to understand also this process and we know water can be routed through thick cold ice. Water generation at the bed is also well understood but the main problem preventing realistic estimates of water generation is lack of detailed information about geothermal heat fluxes and their geographical distribution beneath the ice. Although some average value for geothermal heat flux may suffice, for many purposes it is important that such values are not applied to sub-regions of significantly higher fluxes. Water generated by geothermal heat constitutes a constant supply and will likely maintain a steady system beneath the ice sheet. Such a system may include subglacial lakes as steady features and reconfiguration of the system is tied to time scales on which the ice sheet geometry changes so as to change pressure gradients in the basal system itself. Large scale re-organization of subglacial drainage systems have been observed beneath ice streams. The stability of an entirely subglacially fed drainage system may hence be perturbed by rapid ice flow. In the case of Antarctic ice streams where such behavior has been observed, the ice streams are underlain by deformable sediments. It is

  19. Attributional Style and Depression in Multiple Sclerosis

    Arnett, Peter A.

    2013-01-01

    Several etiologic theories have been proposed to explain depression in the general population. Studying these models and modifying them for use in the multiple sclerosis (MS) population may allow us to better understand depression in MS. According to the reformulated learned helplessness (LH) theory, individuals who attribute negative events to internal, stable, and global causes are more vulnerable to depression. This study differentiated attributional style that was or was not related to MS in 52 patients with MS to test the LH theory in this population and to determine possible differences between illness-related and non-illness-related attributions. Patients were administered measures of attributional style, daily stressors, disability, and depressive symptoms. Participants were more likely to list non-MS-related than MS-related causes of negative events on the Attributional Style Questionnaire (ASQ), and more-disabled participants listed significantly more MS-related causes than did less-disabled individuals. Non-MS-related attributional style correlated with stress and depressive symptoms, but MS-related attributional style did not correlate with disability or depressive symptoms. Stress mediated the effect of non-MS-related attributional style on depressive symptoms. These results suggest that, although attributional style appears to be an important construct in MS, it does not seem to be related directly to depressive symptoms; rather, it is related to more perceived stress, which in turn is related to increased depressive symptoms.

    Abstract Aim. This study investigates which leadership styles can be identified among general practice lead physicians and how they are associated with and predicted by staff and context characteristics like profession, gender, age, work experience, and team size. Method/material. In a cross-sectional study self-administered questionnaires were distributed to staff physicians (42% females) and support staff (98% females) at 101 primary health care centres in North Norway. A total of 127 and 222, respectively, responded (response rate 59%). Items were ranked on Likert scales (range 1–5). Results. Analysis revealed three significantly different styles (mean scores/Cronbach's alpha): change style (3.36/0.898), task style (3.17/0.885), and relation style (2.88/0.900). The lead physicians were perceived as practising change style the most and relation style the least. Males experienced significantly more of all three styles. Support staff scored lowest for all styles. Age was negatively correlated with relation style and change style, while work experience was negatively correlated with change style. No significant association was found between styles and team size. Conclusion. Leadership in rural general practice can be identified in terms of task, relation, and change styles. Change style is the most perceived style. Males seem to be most attentive to leadership styles. However, within the staff physician group, there is less difference between genders. Support staff scores lowest for all styles; this might indicate either less need for leadership or dissatisfaction with leadership. Age and work experience seem to reduce employees’ attention to relation and change styles, indicating that maturity reduces needs for these leadership styles. Due to growing demands for leaders to take care of efficiency and change in general practice, more young female physicians, and more diverse staff groups, these findings may be useful to understand leadership and leadership

  6. AUTOMATIC ARCHITECTURAL STYLE RECOGNITION

    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.

    The aim of this study was to measure happiness in a sample of Brazilian psychiatrists and correlate it with the defense styles used by them and sociodemographic data. This study was observational, cross-sectional, and analytical. Data were collected through self-administered questionnaires by Brazilian psychiatrists who participated in the XXXII Brazilian Congress of Psychiatry, 2014. In this sample of psychiatrists, happiness levels were high (scoring 5.69 of a total of 7), and mature defense styles prevailed, especially humor and anticipation. In a multivariate analysis, having children, good sleep quality, increased sexual interest, and use of defense styles such as humor, anticipation, and idealization all showed a positive relationship with happiness; on the other hand, using defense style such as acting out or annulment demonstrated a negative relationship with happiness. Despite the well-known professional burden that they bear, Brazilian psychiatrists surveyed presented, in general, high levels of subjective well-being and happiness.

    Full Text Available In this research, the geometrical structures of tilted current sheet and tail flapping waves have been analysed based on multiple spacecraft measurements and some features of the tilted current sheets have been made clear for the first time. The geometrical features of the tilted current sheet revealed in this investigation are as follows: (1 The magnetic field lines (MFLs in the tilted current sheet are generally plane curves and the osculating planes in which the MFLs lie are about vertical to the equatorial plane, while the normal of the tilted current sheet leans severely to the dawn or dusk side. (2 The tilted current sheet may become very thin, the half thickness of its neutral sheet is generally much less than the minimum radius of the curvature of the MFLs. (3 In the neutral sheet, the field-aligned current density becomes very large and has a maximum value at the center of the current sheet. (4 In some cases, the current density is a bifurcated one, and the two humps of the current density often superpose two peaks in the gradient of magnetic strength, indicating that the magnetic gradient drift current is possibly responsible for the formation of the two humps of the current density in some tilted current sheets. Tilted current sheets often appear along with tail current sheet flapping waves. It is found that, in the tail flapping current sheets, the minimum curvature radius of the MFLs in the current sheet is rather large with values around 1 RE, while the neutral sheet may be very thin, with its half thickness being several tenths of RE. During the flapping waves, the current sheet is tilted substantially, and the maximum tilt angle is generally larger than 45°. The phase velocities of these flapping waves are several tens km/s, while their periods and wavelengths are several tens of minutes, and several earth radii, respectively.

    The way individuals use humor to interact interpersonally has been associated with general personality, depression, and suicidality. Certain humor styles may moderate the risk for suicide ideation (SI) in individuals who are high in specific risk factors (e.g., thwarted belongingness, perceived burdensomeness). Previous research suggests a relationship between humor styles and borderline personality disorder (BPD) and an increased risk of suicidality and suicide completion in individuals with BPD. Participants (n =176) completed measures of BPD traits, SI, and humor styles. It was hypothesized that BPD traits would be positively correlated with negative humor styles and negatively correlated with positive humor styles, and that humor styles would significantly moderate BPD traits and SI. Results showed that BPD traits were negatively correlated with self-enhancing humor styles and positively correlated with self-defeating humor styles, but that they were not significantly correlated with affiliative or aggressive humor styles. Bootstrapping analyses demonstrated that the affiliative, self-enhancing, and self-defeating humor styles significantly moderated BPD traits and SI, while the aggressive humor style did not.

    2016-01-01

    Heterogeneous image conversion is a critical issue in many computer vision tasks, among which example-based face sketch style synthesis provides a convenient way to make artistic effects for photos. However, existing face sketch style synthesis methods generate stylistic sketches depending on many photo-sketch pairs. This requirement limits the generalization ability of these methods to produce arbitrarily stylistic sketches. To handle such a drawback, we propose a robust face sketch style synthesis method, which can convert photos to arbitrarily stylistic sketches based on only one corresponding template sketch. In the proposed method, a sparse representation-based greedy search strategy is first applied to estimate an initial sketch. Then, multi-scale features and Euclidean distance are employed to select candidate image patches from the initial estimated sketch and the template sketch. In order to further refine the obtained candidate image patches, a multi-feature-based optimization model is introduced. Finally, by assembling the refined candidate image patches, the completed face sketch is obtained. To further enhance the quality of synthesized sketches, a cascaded regression strategy is adopted. Compared with the state-of-the-art face sketch synthesis methods, experimental results on several commonly used face sketch databases and celebrity photos demonstrate the effectiveness of the proposed method.

    Current sheets are important for the structure and dynamics of many plasma systems. In space and astrophysical plasmas they play a crucial role in activity processes, for example by facilitating the release of magnetic energy via processes such as magnetic reconnection. In this contribution we will focus on collisionless plasma systems. A sensible first step in any investigation of physical processes involving current sheets is to find appropriate equilibrium solutions. The theory of collisionless plasma equilibria is well established, but over the past few years there has been a renewed interest in finding equilibrium distribution functions for collisionless current sheets with particular properties, for example for cases where the current density is parallel to the magnetic field (force-free current sheets). This interest is due to a combination of scientific curiosity and potential applications to space and astrophysical plasmas. In this paper we will give an overview of some of the recent developments, discuss their potential applications and address a number of open questions.

    Our goal was to identify how parental feeding practices from the nutrition literature link to general parenting styles from the child development literature to understand how to target parenting practices to increase effectiveness of interventions. Stand-alone parental feeding practices could be targeted independently. However, parental feeding practices linked to parenting styles require interventions treating underlying family dynamics as a whole. To predict parenting styles from feeding practices and to test three hypotheses: restriction and pressure to eat are positively related whereas responsibility, monitoring, modeling, and encouraging are negatively related to an authoritarian parenting style; responsibility, monitoring, modeling, and encouraging are positively related whereas restriction and pressure to eat are negatively related to an authoritative parenting style; a permissive parenting style is negatively linked with all six feeding practices. Baseline data of a randomized-controlled intervention study. Two hundred thirty-nine parents (93.5% mothers) of first-grade children (134 boys, 105 girls) enrolled in rural public schools. Parental responses to encouraging and modeling questionnaires and the Child Feeding Questionnaire, as well as parenting styles measured by the Parenting Styles and Dimensions Questionnaire. Correlation and regression analyses. Feeding practices explained 21%, 15%, and 8% of the variance in authoritative, authoritarian, and permissive parenting, respectively. Restriction, pressure to eat, and monitoring (negative) significantly predicted an authoritarian style (Hypothesis 1); responsibility, restriction (negative), monitoring, and modeling predicted an authoritative style (Hypothesis 2); and modeling (negative) and restriction significantly predicted a permissive style (Hypothesis 3). Parental feeding practices with young children predict general parenting styles. Interventions that fail to address underlying parenting styles

Based on this perspective, each of individuals will approach the general learning experiences in a personal and individualized way related to his/her performance and behavior. This study is to analyze the characteristics of product design using Kansei Engineering approach towards the student learning style based on Felder and Soloman's theory. Using the 8 (eight spectacles designs proposed comparing the emotional feeling towards design of product, the study involved 100 students who are using spectacles as the respondents. Focusing on the perception and input dimensions of the Felder-Soloman learning styles comprised in 22 questions and the Crane cognitive alert styles in 9 questions, the result of study shows that the students who are using spectacles are dominated by “the visual” type of Felder-Soloman learning styles. In addition, based on the using of Kansei Engineering, this study also found that the respondents tend to interpret the rimless design of spectacles as “fragile,” “unattractive,” “old-fashion” product, while the design with thicker frame as “durable,” “attractive,” cool,” “ergonomic” product. In this study, there are also the significant correlations proved against the preferences of product design based on quality affective (Kansei Engineering using learning styles and cognitive alert styles.

  8. Plasmoid Instability in Forming Current Sheets

    2017-12-01

    The plasmoid instability has revolutionized our understanding of magnetic reconnection in astrophysical environments. By preventing the formation of highly elongated reconnection layers, it is crucial in enabling the rapid energy conversion rates that are characteristic of many astrophysical phenomena. Most previous studies have focused on Sweet-Parker current sheets, which are unattainable in typical astrophysical systems. Here we derive a general set of scaling laws for the plasmoid instability in resistive and visco-resistive current sheets that evolve over time. Our method relies on a principle of least time that enables us to determine the properties of the reconnecting current sheet (aspect ratio and elapsed time) and the plasmoid instability (growth rate, wavenumber, inner layer width) at the end of the linear phase. After this phase the reconnecting current sheet is disrupted and fast reconnection can occur. The scaling laws of the plasmoid instability are not simple power laws, and they depend on the Lundquist number (S), the magnetic Prandtl number (P m ), the noise of the system ({\\psi }0), the characteristic rate of current sheet evolution (1/τ ), and the thinning process. We also demonstrate that previous scalings are inapplicable to the vast majority of astrophysical systems. We explore the implications of the new scaling relations in astrophysical systems such as the solar corona and the interstellar medium. In both of these systems, we show that our scaling laws yield values for the growth rate, wavenumber, and aspect ratio that are much smaller than the Sweet-Parker-based scalings.

  12. Shape Optimization of Swimming Sheets

    Wilkening, J.; Hosoi, A.E.

    2005-03-01

    The swimming behavior of a flexible sheet which moves by propagating deformation waves along its body was first studied by G. I. Taylor in 1951. In addition to being of theoretical interest, this problem serves as a useful model of the locomotion of gastropods and various micro-organisms. Although the mechanics of swimming via wave propagation has been studied extensively, relatively little work has been done to define or describe optimal swimming by this mechanism.We carry out this objective for a sheet that is separated from a rigid substrate by a thin film of viscous Newtonian fluid. Using a lubrication approximation to model the dynamics, we derive the relevant Euler-Lagrange equations to optimize swimming speed and efficiency. The optimization equations are solved numerically using two different schemes: a limited memory BFGS method that uses cubic splines to represent the wave profile, and a multi-shooting Runge-Kutta approach that uses the Levenberg-Marquardt method to vary the parameters of the equations until the constraints are satisfied. The former approach is less efficient but generalizes nicely to the non-lubrication setting. For each optimization problem we obtain a one parameter family of solutions that becomes singular in a self-similar fashion as the parameter approaches a critical value. We explore the validity of the lubrication approximation near this singular limit by monitoring higher order corrections to the zeroth order theory and by comparing the results with finite element solutions of the full Stokes equations.

    The term "learning style" refers to the fact that each person has a different way of accumulating knowledge. While some prefer listening to learn better, others need to write or they only need to read the text or see a picture to later remember. According to Fleming and Mills the learning styles can be classified in Visual, Auditory and Kinesthetic. There is no evidence that teaching according to the learning style can help a person, yet this cannot be ignored. In this study, a number of 230 medical students were questioned in order to determine their learning style. We determined that 73% of the students prefer one learning style, 22% prefer to learn using equally two learning style, while the rest prefer three learning styles. According to this study the distribution of the learning styles is as following: 33% visual, 26% auditory, 14% kinesthetic, 12% visual and auditory styles equally, 6% visual and kinesthetic, 4% auditory and kinesthetic and 5% all three styles. 32 % of the students that participated at this study are from UMF Craiova, 32% from UMF Carol Davila, 11% University of Medicine T Popa, Iasi, 9% UMF Cluj Iulius Hatieganu. The way medical students learn is different from the general population. This is why it is important when teaching to considerate how the students learn in order to facilitate the learning.

    What does it mean to have a "verbal cognitive style?" We adopt the view that a cognitive style represents a cognitive strategy, and we posit the conversion hypothesis - the notion that individuals with a proclivity for the verbal cognitive style tend to code nonverbal information into the verbal domain. Here we used repetitive transcranial magnetic stimulation (rTMS) to disrupt this hypothesized verbal conversion strategy. Following our previous research implicating left supramarginal gyrus (SMG) in the verbal cognitive style, we used an fMRI paradigm to localize left SMG activity for each subject, then these functional peaks became rTMS targets. Left SMG stimulation impaired performance during a task requiring conversion from pictures to verbal labels. The magnitude of this effect was predicted by individuals' level of verbal cognitive style, supporting the hypothesized role of left SMG in the verbal labeling strategy, and more generally supporting the conversion hypothesis for cognitive styles.

    2011-01-01

    Light sheet fluorescence microscopy (LSFM) functions as a non-destructive microtome and microscope that uses a plane of light to optically section and view tissues with subcellular resolution. This method is well suited for imaging deep within transparent tissues or within whole organisms, and because tissues are exposed to only a thin plane of light, specimen photobleaching and phototoxicity are minimized compared to wide-field fluorescence, confocal, or multiphoton microscopy. LSFMs produce well-registered serial sections that are suitable for three-dimensional reconstruction of tissue structures. Because of a lack of a commercial LSFM microscope, numerous versions of light sheet microscopes have been constructed by different investigators. This review describes development of the technology, reviews existing devices, provides details of one LSFM device, and shows examples of images and three-dimensional reconstructions of tissues that were produced by LSFM.

    To assess the nutrition communication styles of Dutch family doctors and in particular to assess its psychosocial and sociodemographic correlates. A cross-sectional study in which a representative sample of 600 Dutch family doctors completed a questionnaire. The survey was conducted in October and November 2004 in the Netherlands. A total of 267 family doctors completed the questionnaire (response rate 45%). Principal component factor analyses with varimax rotation were performed to construct factors. Cronbach's alpha was used as an index of reliability. Our hypothetical model for nutrition communication style was tested using multiple regression analysis, combining the forward and backward procedures under the condition of the same results. Many family doctors felt at ease with a motivational nutrition communication style. The main predictor for motivational nutrition communication style was task perception of prevention (26%). Some individual and environmental correlates had an additional influence (explained variance 49%). Other styles showed explained variances up to 57%. The motivational style was the best predictor for actual nutrition communication behaviour (35%), while the confrontational style was the best predictor for actual nutrition communication behaviour towards overweight (34%). In contemporary busy practice, family doctors seem to rely on their predominant nutrition communication style to deal with standard situations efficiently: for the majority, this proved to be the motivational nutrition communication style. Moreover, family doctors used a combination of styles. This study suggests that family doctors behave like chameleons, by adapting their style to the specific circumstances, like context, time and patient. If family doctors communicate about nutrition in general, they select any of the five nutrition communication styles. If they communicate about overweight, they pick either the confrontational or motivational style.

    Full Text Available Theory of attachment primarily described early relationships between a child and his caretakers. In the last twenty years there is a growing interest in adult attachment research. Theories and research findings of adult attachment stem from two different methodological approaches. The first approach measures adult attachment through Adult Attachment Interview (AAI; Main, 1991 where the attachment is assessed through the narratives of adult people of their early child experiences with their primary caretakers. The second approach measures adult attachment with the help of self-evaluative questionnaires, developed by (a Hazan and Shaver (1987 who started this approach in the field of personality and social psychology, and (b Bartholomew and Horowitz (1991. Research shows that there is significant correlation between early and adult attachment style. Attachment styles are passed from generation to generation. Basic adult attachment styles are: securely attached, preoccupied, fearful-avoidant, dismissing-avoidant and disorganized. Previous research using Barholomew and Horowitz (1991 Relationship Questionnaire on 176 Slovenian students showed that 48% students are securely attached, 29% are fearful-avoidant, 10% are dismissing-avoidant, and 13% have preoccupied attachment style. Theory of attachment is very useful for understanding the behavior and subjective experiences of children and adults. It is applicable to different contexts (psychotherapy, counseling, education ....

    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.

    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.

    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.

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.

  10. Relating Church-Style and Curry-Style Subtyping

    2011-01-01

    Full Text Available Type theories with higher-order subtyping or singleton types are examples of systems where computation rules for variables are affected by type information in the context. A complication for these systems is that bounds declared in the context do not interact well with the logical relation proof of completeness or termination. This paper proposes a natural modification to the type syntax for F-Omega-Sub, adding variable's bound to the variable type constructor, thereby separating the computational behavior of the variable from the context. The algorithm for subtyping in F-Omega-Sub can then be given on types without context or kind information. As a consequence, the metatheory follows the general approach for type systems without computational information in the context, including a simple logical relation definition without Kripke-style indexing by context. This new presentation of the system is shown to be equivalent to the traditional presentation without bounds on the variable type constructor.

    This article develops and tests a reformation of Baumrind's typology of authoritarian, permissive, and authoritative parenting styles in the context of adolescent school performance. Using a large and diverse sample of San Francisco Bay Area high school students (N = 7,836), we found that both authoritarian and permissive parenting styles were negatively associated with grades, and authoritative parenting was positively associated with grades. Parenting styles generally showed the expected relation to grades across gender, age, parental education, ethnic, and family structure categories. Authoritarian parenting tended to have a stronger association with grades than did the other 2 parenting styles, except among Hispanic males. The full typology best predicted grades among white students. Pure authoritative families (high on authoritative but not high on the other 2 indices) had the highest mean grades, while inconsistent families that combine authoritarian parenting with other parenting styles had the lowest grades.

    Full Text Available Generally, different students employ different learning styles dur-ing their studies and medical students are exposed to diverse methods of teaching. Therefore, understanding students’ learning style preference is an important consideration for a high quality and effective teaching and learning process.The aim of the study was to study the variation of learning styles among pre-clinical medical students of SEGi University, Malaysia. A cross-sectional study was performed by using VARK (Visual, Audio, Reading and Kinaesthetic questionnaire version 7.2 to assess the learning style preference of 98 (n=98 pre-clinical medical students in SEGi University. The questionnaire consists of 16 items which identify four different learning styles: visual, aural, reading/writing and kin-esthetic. Descriptive statistics were used to identify the learning styles of students. 61 students preferred multimodal as their learning style, out of which 43 (70% of them were female stu-dents and 18 (30% were male students. 37 students preferred unimodal as their learning style out of which 22 (59% of them were female students and 15 (41% were male students. In addi-tion, female students had more diverse preferences than male students by having 10 out of the other 11 possible combinations in multimodal learning style of preference, whereas the male stu-dents only had 5 out of the 11 combinations. In this study, there was no significant gender difference in the percentages of males and female students who preferred unimodal and multimodal styles of information presentation (P= 0.263; α=0.05. To con-clude, the majority of students of both genders had chosen quad-modal as their learning style preference. The results of this study can provide useful information for improving the quality of the teaching and learning experiences of students.

    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...... 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...... ties different social practices together. While organization makes the connections between social practices durable, entrepreneurship disrupts such patterns.

    Full Text Available This paper aims to study the management style of the Spanish advertising agencies. For this purpose, it explores the way in which the dimensions that define the nature of this concept arise in the sector chosen. 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.

  1. [Effectiveness of managing styles of nursing management staff].

    Science.gov (United States)

    Stychno, Ewa

    2002-01-01

    There are many possibilities of the division of the managing styles. In theory one can distinguish two basic styles: directive and integrative. Generalisations describing both styles result in the fact that they do not reflect reality taking place at work. Because of it they cannot be applied in such a form. Therefore, it is necessary to build up the theoretical concept of the managing styles through decreasing their generality and adjusting them to the reality requirements at the same time. For the reality of management Reddin concept seems to be useful. It describes the organizational behaviour of managers. He noticed that the managing style is effective when it fits into the manager's situation whereas it is ineffective in such a situation, when the manager cannot select and adjust the managing techniques to the circumstances of the concrete decision-taking situation. Putting together 3 handling ways: orientation on assignments, orientation on staff, effectiveness, 8 managing can be differentiated. The aim of the paper was an attempt to check what managing styles are used by the nursing management staff working in hospitals. To determine the managing style a questionnaire consisting of 64 statements divided into 8 groups was applied. The examined persons were assigned to distribute 10 points among the statements belonging to each group of tasks which are supposed to specify their solution in the best way. The nursing management staff prefer the styles belonging to the more effective one in which there is a high orientation on staff.

  4. Rondocubism versus National Style

    Directory of Open Access Journals (Sweden)

    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.

    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.

  6. Stiffness Matrices and Anisotropy in the Trapezoidal Corrugated Composite Sheets

    Full Text Available In the some applications like as morphing technology, high strain and anisotropic behavior are essential design requirements. The corrugated composite sheets due to their special geometries have potential to high deflection under axial loading through longitudinal direction of corrugation. In this research, the strain and the anisotropic behavior of corrugated composite sheets are investigated by fabricating glass/epoxy samples with trapezoidal geometries. For evaluation of the mechanical behavior of the composites the samples were subjected to tension and flexural tests in the longitudinal and transverse directions of corrugation. In order to determine anisotropic behavior of the corrugated sheets, two approaches were introduced: (1 tensile anisotropic (E* and (2 flexural anisotropic (D*. The anisotropic behavior and ultimate deflections were investigated theoretically and experimentally. In this paper, mechanical behaviors based on theoretical and experimental analysis including the elastic constants and stiffness matrices of trapezoidal corrugated composite sheets were studied and the results were verified by finite element method. The results of the numerical and analytical solutions were compared with those of experimental tests. Finally, the load-displacement curves of tensile tests in longitudinal direction of corrugation, the ultimate deflection and anisotropy behavior of these exclusive composite sheets in the corrugated composite sheets were studied experimentally. The experimental results of the trapezoidal corrugated sheets showed that one of the most important parameters in the ultimate strain was amplitude of the corrugation elements. Generally, increasing the amplitude and element per length unit of trapezoidal corrugated specimen led to higher ultimate strain.

  7. Continuous Casting for Aluminum Sheet: a Product Perspective

    Sanders, Robert E.

    2012-02-01

    Continuous casting processes have been used successfully for more than 50 years to reduce the cost of manufacturing a variety of aluminum rolled products. Approximately 25% of North American flat-rolled sheet and foil is sourced from twin-roll cast or slab cast processes. Twin roll-casters provide a cost-effective solution for producing foil and light-gauge sheet from relatively low-alloyed aluminum (1xxx and 8xxx alloys). Slab casters, particularly Hazelett twin-belt machines, are well utilized in the production of 3xxx or 5xxx painted building products which require moderate strength and good corrosion resistance. Both foil and painted sheet are cost-sensitive commodity products with well-known metallurgical and quality requirements. There have been extensive trials and modest successes with continuous cast can stock and automotive sheet. However, they have not been widely adopted commercially due to generally lower levels of surface quality and formability compared with sheet produced from scalped direct chill (DC) cast ingot. The metallurgical requirements for can and auto sheet are considered in more detail with emphasis on the microstructural features which limit their application, e.g., particle distribution, grain size, and texture. Looking forward, slab casting offers the most viable opportunity for producing strong (i.e., higher alloy content), formable structural auto sheet with acceptable surface quality.

    2015-05-01

    Clothing recognition is a societally and commercially important yet extremely challenging problem due to large variations in clothing appearance, layering, style, and body shape and pose. In this paper, we tackle the clothing parsing problem using a retrieval-based approach. For a query image, we find similar styles from a large database of tagged fashion images and use these examples to recognize clothing items in the query. Our approach combines parsing from: pre-trained global clothing models, local clothing models learned on the fly from retrieved examples, and transferred parse-masks (Paper Doll item transfer) from retrieved examples. We evaluate our approach extensively and show significant improvements over previous state-of-the-art for both localization (clothing parsing given weak supervision in the form of tags) and detection (general clothing parsing). Our experimental results also indicate that the general pose estimation problem can benefit from clothing parsing.

    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. When a group of students demonstrate a preference for particular learning style teachers can develop their curriculum along their learning styleKey words: LEARNING STYLES, NURSING STUDENTS, FRESHMAN, SOPHOMORE, JUNIOR, SENIOR

    2013-10-01

    With vertical integration, registrars and medical students attend the same educational workshops. It is not known whether these learners have similar or different learning styles related to their level of education within the medical training schema. This study aims to collect information about learning styles with a view to changing teaching strategies. If a significant difference is demonstrated this will impact on required approaches to teaching. The VARK learning inventory questionnaire was administered to 36 general practice registrars and 20 medical students. The learning styles were compared as individuals and then related to their level of education within the medical training schema. Students had a greater preference for multimodal learning compared with registrars (62.5 per cent versus 33.3 per cent, respectively). More than half of the registrars preferred uni or bimodal learning modalities, compared with one-third of the medical students. The present workshop format based on visual and aural material will not match the learning needs of most learners. This small study has shown that the majority of medical students and registrars could have their learning preferences better met by the addition of written material to the workshop series. Surprisingly, a significantly larger number of medical students than registrars appeared to be broadly multimodal in their learning style, and this warrants further research. © 2013 John Wiley & Sons Ltd.

    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.

    The importance of the social environment for dietary behaviour has been highlighted in the past decade. A type of environmental influence that has received increasing research attention in recent years is the influence that parents can have on their children's dietary behaviour through food-related parenting practices. Much of the work done so far, however, has reported inconsistent findings and poorly understood mechanisms of influence. The present study aimed to explore the possible environmental influence of general parenting style on adolescent food choice patterns. Data were collected at schools (N=643; mean age 16.5 years), using self-administered questionnaires on parenting style, fruit intake behaviour and fruit-specific cognitions. Consistent and theoretically predictable differences were found between adolescents who described their parents as authoritative, authoritarian, indulgent or neglectful. Fruit consumption and fruit-specific cognitions were most favourable among adolescents who were being raised with an authoritative parenting style. Children of parents with indulgent parenting styles consumed more fruit than adolescents from authoritarian or neglectful homes. Consequences of these results for the interpretation of earlier studies on the influence of parenting practices are discussed, and a research model is proposed for future studies of parental influences on adolescent dietary behaviours.

  15. Influence of a dynamic ocean on Permian ice sheet growth

    Science.gov (United States)

    Tilevitz, C.; Poulsen, C. J.

    2015-12-01

    Previous studies using an atmospheric general circulation model have shown that extensive ice sheets can grow on the Gondwanan supercontinent during the late Paleozoic (~340-250 Ma) under modern orbital parameters and CO2 levels at or below two times pre-industrial values (CO2 ≤560 ppm). Proxy records for the late Paleozoic suggest a wide range of potential CO2 values, but the range of values that allows for the growth of large ice sheets is much smaller. A prescribed slab ocean with diffusive heat transport (using modern heat fluxes) was used for those experiments, but lacks the ability to accurately capture the ocean dynamics of the Paleozoic. Here, within the NCAR Community Earth System Model framework, we use a fully dynamic ocean model to explore Permian ice sheet growth under more realistic conditions. Fully coupled CESM simulations for two CO2 levels (280 & 560 ppm) are run until the ocean equilibrates (~1500-2000 years). Climatologies from those simulations are then used to drive a three-dimensional dynamic ice sheet model in an asynchronous coupling, in which the ice sheet model is run until the ice sheets equilibrate. The ice sheet geometry and height are then used to update the coupled ocean-atmosphere model, which is run for ~20 years, until the climate system re-equilibrates. Preliminary results show that ice sheet growth at the higher CO2 value is small in comparison with ice sheet growth in the lower CO2 environment, which is consistent with previous late Paleozoic modeling studies. The latitudinal temperature gradient is also steeper at 280 ppm CO2 than at 560 ppm, though the dynamic ocean buffers some of these changes relative to what they would be for a slab ocean.

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.

  5. Modelling the Antarctic Ice Sheet

    Pedersen, Jens Olaf Pepke; Holm, A.

    2015-01-01

    The Antarctic ice sheet is a major player in the Earth’s climate system and is by far the largest depository of fresh water on the planet. Ice stored in the Antarctic ice sheet (AIS) contains enough water to raise sea level by about 58 m, and ice loss from Antarctica contributed significantly...... to sea level high stands during past interglacial periods. A number of AIS models have been developed and applied to try to understand the workings of the AIS and to form a robust basis for future projections of the AIS contribution to sea level change. The recent DCESS (Danish Center for Earth System...... Science) Antarctic Ice Sheet (DAIS) model (Shaffer 2014) is forced by reconstructed time series of Antarctic temperature, global sea level and ocean subsurface temperature over the last two glacial cycles. In this talk a modelling work of the Antarctic ice sheet over most of the Cenozoic era using...

  8. Style in science communication.

    Bucchi, Massimiano

    2013-11-01

    There is little doubt that during the past few decades science communication efforts aimed at non-expert audiences have increased in quantity and intensity on a global scale. Public engagement and outreach activities have now become a routine - when not a prominent - feature for several research institutions in Europe. However, it would be difficult for both scholars and those involved in science communication to agree on the impact of these activities, on the long-term implications of the 'science communication movement' and on the indicators we should develop and employ in order to assess impact. The paper argues that quality is a relevant issue and challenge for contemporary science communication. Style is relevant to addressing that challenge, insofar as it relates to discussions about how to strengthen the quality of science communication, suggesting a different perspective other than the traditional normative/prescriptive framework. The notion of style also fruitfully connects the debate on science communication with a rich tradition of studies in the history and sociology of science.

  9. Ward leadership styles.

    Science.gov (United States)

    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)

    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.

    Thin sheets of resistive or dielectric material are commonly encountered in radar cross section calculations. Analysis of such sheets is simplified by using sheet impedances. In this paper it is shown that sheet impedances can be modeled easily and accurately using Finite Difference Time Domain (FDTD) methods.

  14. Stress transmission across grounding lines and marine ice sheet instability

    Science.gov (United States)

    Docquier, David; Nick, Faezeh M.; Perichon, Laura; Pattyn, Frank

    2010-05-01

    The stability of marine ice sheets is largely controlled by the dynamic behaviour of the grounding line, i.e., the contact of the bottom of the ice sheet resting on the bedrock with the ocean water. Marine ice sheet instability implies that an ice sheet on a downward sloping bedrock towards the interior will never find stable equilibria, hence leading to ice sheet collapse, unless an upward slope is reached (Schoof, 2007). The latter study shows that steady state solutions using a boundary layer theory for ice flux are in very close agreement with numerical resolutions that resolve the transition zone. However, the time dependent response of grounding line migration is not predicted by this theory. Precise knowledge of this response is essential for assessing the short term impact of accelerated ice discharge on sea level rise. Here we present the results of MISMIP-type (Marine Ice Sheet Model Intercomparison Project) experiments with different sets of numerical flowline models (fixed and moving grid) that solve the stress field in the transition zone according to different approximations to the Stokes equations. These models include shallow-ice (SIA0), shallow-shelf (L1L2) and higher-order (LMLa) approximations, and combinations of these types. All experiments are run at different spatial resolutions and for different sizes of the transition zone (high to low friction). The comparison of several stress approximants allows us to evaluate which stress components in the flow direction are important to the general behaviour of grounding line migration.

  15. Biological processes on glacier and ice sheet surfaces

    Science.gov (United States)

    Stibal, Marek; Šabacká, Marie; Žárský, Jakub

    2012-11-01

    Glaciers and ice sheets are melting in response to climate warming. Whereas the physical behaviour of glaciers has been studied intensively, the biological processes associated with glaciers and ice sheets have received less attention. Nevertheless, field observations and laboratory experiments suggest that biological processes that occur on the surface of glaciers and ice sheets -- collectively termed supraglacial environments -- can affect the physical behaviour of glaciers by changing surface reflectivity. Furthermore, supraglacial cyanobacteria and algae capture carbon dioxide from the atmosphere and convert it into organic matter. Supraglacial microbes break down this material, together with organic matter transported from further afield, and generate carbon dioxide that is released back into the atmosphere. The balance between these two processes will determine whether a glacier is a net sink or source of carbon dioxide. In general, ice sheet interiors seem to function as sinks, whereas ice sheet edges and small glaciers act as a source. Meltwaters flush microbially modified organic matter and pollutants out of the glacier, with potential consequences for downstream ecosystems. We conclude that microbes living on glaciers and ice sheets are an integral part of both the glacial environment and the Earth's ecosystem.

  16. Conspiracy theory and cognitive style: a worldview.

    Dagnall, Neil; Drinkwater, Kenneth; Parker, Andrew; Denovan, Andrew; Parton, Megan

    2015-01-01

    This paper assessed whether belief in conspiracy theories was associated with a particularly cognitive style (worldview). The sample comprised 223 volunteers recruited via convenience sampling and included undergraduates, postgraduates, university employees, and alumni. Respondents completed measures assessing a range of cognitive-perceptual factors (schizotypy, delusional ideation, and hallucination proneness) and conspiratorial beliefs (general attitudes toward conspiracist thinking and endorsement of individual conspiracies). Positive symptoms of schizotypy, particularly the cognitive-perceptual factor, correlated positively with conspiracist beliefs. The best predictor of belief in conspiracies was delusional ideation. Consistent with the notion of a coherent conspiratorial mindset, scores across conspiracy measures correlated strongly. Whilst findings supported the view that belief in conspiracies, within the sub-clinical population, was associated with a delusional thinking style, cognitive-perceptual factors in combination accounted for only 32% of the variance.

    Objective To provide preliminary descriptive data on caregiver and child weight status, parenting styles, feeding styles, and feeding practices of a small American Indian sample. Methods Participants included a subsample of American Indian caregivers (n = 23) identified from a larger study that was conducted in five states. Using previously validated instruments, means, standard deviations, and ranges for general parenting styles, feeding styles, and feeding practices were explored. Results In general, most caregivers reported healthy feeding practices. Most caregivers scored higher on responsive compared to restrictive or permissive in general parenting. Of the sample, 12 caregivers (52.2 %) were classified in the indulgent feeding style category, 5 caregivers (21.7 %) were classified as authoritative, 5 (21.7 %) uninvolved, and 1 (4.3 %) authoritarian. Conclusions More investigations are needed to explore questions raised by this study about using common tools that measure childhood obesity with American Indian families.

    Full Text Available This article is about the communication style of the staff directive, farther beyond the interpretations made by some authors, considering it as a style of direction. Some ideas about the activity of direction in education are focused, as a natural scenery where the activity of communication is conceived, developed, evaluated and feedback, in contrast to some other authors and works that do it from a perspective of a style of direction without a rigorous scientific foundation, and without establishing the limits between one classification and the other, this is a well discussed issue, on authors point of view is the least important. Our considerations are based on the idea that every person has its own way of communicating that any position one may take is intertwined to the natural method and in some occasion’s reductions ideas singularize it. We are in favour of the criterion that the style of communication of staff leaders is an indissoluble and inseparable aspect of directing competence. Some arguments are offered in this level of analysis; the indicators and categories through which the first can be assessed, departing from the individuals of the activity of direction’s behaviour are offered, as well as a matrix for the collection of the data and their alternatives for processing them.

    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.

    1989-02-01

    The study investigated how coping style differences affected performance on the cold pressor task. Reactions of "monitors" (individuals who prefer having information about stressors) and "blunters" (individuals who avoid cues connected with stressors) were compared, using different instructional sets. The study also assessed the effectiveness of paradoxical intention compared to more traditional cognitive strategies. Monitors and blunters were identified using Miller's recently developed Behavioral Style Scale. All instructional sets improved performance in comparison to a control condition, and individuals generally did better when an instructional set supported their preferred coping style. Paradoxical intention did not show any decided advantage over other strategies. The desirability of designing stress management programs to fit individual coping style patterns is discussed.

    1999-11-01

    To examine the relation between psychiatric symptoms and defense mechanisms, we administered two questionnaires, the Symptom Check-list 90 (SCL-90) and the Defense Style Questionnaire (DSQ) to 122 psychiatric out-patients and to a community sample of 337 subjects. Using regression analysis, we found that 51.8% of the variation in subject's Global Severity Index value could be explained by his defense style. Of the three defense styles, the immature style explained most of the variation in the symptoms. We found little overall evidence for specific connections between particular defenses and symptoms. Projection and dissociation were central in most of the symptom dimensions. We compared patients and controls with the same level of general symptom severity and found that patients used significantly more devaluation and splitting, and controls used significantly more altruism and idealization. Whether defenses predispose to certain symptomatology or are one of its aspects is discussed.

    2005-02-01

    The extent to which general parenting represents feeding styles in ethnically diverse populations is not well documented. Existing measures of child feeding have focused almost exclusively on specific behaviors of European-American parents. A valid and reliable instrument was developed to identify feeding styles in parents of low-income minority preschoolers. Two hundred thirty-one parents (130 Hispanic; 101 African-American) completed questionnaires on feeding practices and parenting styles. Based on self-reported feeding behavior, parents were assigned to four feeding styles (authoritarian, n=84; authoritative, n=34; indulgent, n=80; and uninvolved, n=33). Convergent validity was evaluated by relating feeding styles to independent measures of general parenting and authoritarian feeding practices. Authoritarian feeding styles were associated with higher levels of general parental control and authoritarian feeding practices. Alternatively, authoritative feeding styles were associated with higher levels of general parental responsiveness. Among the two permissive feeding styles, Hispanic parents were more likely to be indulgent, whereas African-American parents were more likely to be uninvolved. Further, differences were found among the feeding styles on an independent measure of child's body mass index.

  11. Horizontal electromagnetic casting of thin metal sheets

    Hull, John R.; Lari, Robert J.; Praeg, Walter F.; Turner, Larry R.

    1987-01-01

    Thin metal sheets are cast by magnetically suspending molten metal deposited within a ferromagnetic yoke and between AC conducting coils and linearly displacing the magnetically levitated liquid metal while it is being cooled to form a solid metal sheet. Magnetic flux increases as the molten metal sheet moves downward and decreases as the molten metal sheet moves upward to stabilize the sheet and maintain it in equilibrium as it is linearly displaced and solidified by cooling gases. A conducting shield is electrically coupled to the molten metal sheet by means of either metal sheet engaging rollers or brushes on the solidified metal, and by means of an electrode in the vessel containing the molten metal thereby providing a return path for the eddy currents induced in the metal sheet by the AC coil generated magnetic flux. Variation in the geometry of the conducting shield allows the magnetic flux between the metal sheet and the conducting shield to be varied and the thickness in surface quality of the metal sheet to be controlled. Side guards provide lateral containment for the molten metal sheet and stabilize and shape the magnetic field while a leader sheet having electromagnetic characteristics similar to those of the metal sheet is used to start the casting process and precedes the molten metal sheet through the magnet and forms a continuous sheet therewith. The magnet may be either U-shaped with a single racetrack coil or may be rectangular with a pair of facing bedstead coils.

    2016-04-01

    Full Text Available The aim of this study was to investigate the relationship between parenting styles and children’s social skills, establishing significant correlations between those two constructs. A total of 202 children, 7 to 10 years old, male and female, attending second to fourth year of government schools in São Paulo, Brazil, were participants of this research. They collectively completed Children’s Social Skills Test (THAS-C and Parental Styles Inventory (IEP. Results suggest that positive parental styles are predictors of altruism, while negative parental styles are predictors of assertiveness, conversation, and social confidence. Regarding general social skills, variables that offered the best probable model were positive monitoring, lax discipline, moral behavior, and physical abuse (the higher the general social skill, the lesser the abusive parenting styles. As a conclusion, it seems that different social skills are related to positive and negative parenting styles, reinforcing the idea of a social skill as an attribute of behavior.

  14. Military leaders and followers--do they have different decision styles?

    Science.gov (United States)

    Thunholm, Peter

    2009-08-01

    There are five different, although not mutually exclusive, styles exhibited by military officers when making decisions: rational, intuitive, dependent, avoidant, and spontaneous (Scott & Bruce, 1995). The purpose was to investigate if elected leaders of military planning teams had a different configuration of decision-making styles than their team members. Participants were 98 army captains organized in 16 brigade-level planning teams. The results indicate that team leaders tended to be more spontaneous and less rational, dependent and avoidant in their style configuration than their team members. One possible explanation is that the style configuration exhibited by many of the elected leaders comes through to others as forcefulness and decisiveness and that such a profile is in line with a general leadership culture. The results also provide support for the General Decision-Making Style inventory as a measurement of decision styles, because they suggest that the self-reports coincide with displayed, observable behavior.

As basic materials steel sheet, zinc-coated steel sheet, copper sheet and brass sheet 100 x 20 x 1 mm was the test samples size. Always two sheets were cleaned and jointed together. For heating the propane-butane + air flame was used. Then the tested assemblies were loaded using the universal tensile-strength testing machine till to failure. At the tests the force needed for assemblies failure and failure type (in soldered joint, in basic material were recorded. From measured data the solder strength was calculated. From the experiment results it follows that from the point of view of the soldered joints strength as well of the solder strength relatively small differences were found. At the same time it is evident that the joint strength and solder strength depend on soldered material type and on soldered joint lapping length. On the basis of carried out experiments it can be stated that the substitution of lead solders by leadless solders is possible without risk of soldered joints strength decrease.

  19. Climatic Conditions for modelling the Northern Hemisphere ice sheets throughout the ice age cycle

    Directory of Open Access Journals (Sweden)

    A. Abe-Ouchi

    2007-07-01

    Full Text Available The ice sheet-climate interaction as well as the climatic response to orbital parameters and atmospheric CO2 concentration are examined in order to drive an ice sheet model throughout an ice age cycle. Feedback processes between ice sheet and atmosphere are analyzed by numerical experiments using a high resolution General Circulation Model (GCM under different conditions at the Last Glacial Maximum. Among the proposed processes, the ice albedo feedback, the elevation-mass balance feedback and the desertification effect over the ice sheet were found to be the dominant processes for the ice-sheet mass balance. For the elevation-mass balance feedback, the temperature lapse rate over the ice sheet is proposed to be weaker than assumed in previous studies. Within the plausible range of parameters related to these processes, the ice sheet response to the orbital parameters and atmospheric CO2 concentration for the last glacial/interglacial cycle was simulated in terms of both ice volume and geographical distribution, using a three-dimensional ice-sheet model. Careful treatment of climate-ice sheet feedback is essential for a reliable simulation of the ice sheet changes during ice age cycles.

    2009-10-01

    Full Text Available Kinetic structure of embedded thin horizontal current sheets is investigated. Current density estimated by curlometer technique is in general agreement with a sum of electron and proton currents. Embedding of observed thin current sheets in the much wider plasma sheet is apparent in the current density profiles. Ion velocity distributions consist of two parts: the cold non-drifting core likely belongs to the plasma sheet background, while the hotter asymmetric "wings" carry the main portion of the current. Oxygen ions (if present and higher-energy tails of distribution function can contribute up to 30% of the total current. We compared current density profiles across sheets with three typical current sheet models. Models which allow embedding, describe observed structures equally well at the level of experimental accuracy.

    Sharma, Amit; Yadava, Vinod

    2018-01-01

    Cutting of sheet material is considered as an important process due to its relevance among products of everyday life such as aircrafts, ships, cars, furniture etc. Among various sheet cutting processes (ASCPs), laser beam cutting is one of the most capable ASCP to create complex geometries with stringent design requirements in difficult-to-cut sheet materials. Based on the recent research work in the area of sheet cutting, it is found that the Nd-YAG laser is used for cutting of sheet material in general and reflective sheet material in particular. This paper reviews the experimental analysis of Nd-YAG laser cutting process, carried out to study the influence of laser cutting parameters on the process performance index. The significance of experimental modeling and different optimization approaches employed by various researchers has also been discussed in this study.

    Background Knowledge of coping styles is useful in clinical diagnosis and suggesting specific therapeutic interventions. However, the latent structures and relationships between different aspects of coping styles have not been fully clarified. A full information item bifactor model will be beneficial to future research. Objective One goal of this study is identification of the best fit statistical model of coping styles. A second goal is entails extended analyses of latent relationships among different coping styles. In general, such research should offer greater understanding of the mechanisms of coping styles and provide insights into coping with stress. Methods Coping Styles Questionnaire (CSQ) and Generalized Self-Efficacy Scale (GSES) were administrated to officers suffering from military stress. Confirmatory Factor Analyses was performed to indentify the best fit model. A hierarchical item response model (bifactor model) was adopted to analyze the data. Additionally, correlations among coping styles and self-efficacy were compared using both original and bifactor models. Results Results showed a bifactor model best fit the data. Item loadings on general and specific factors varied among different coping styles. All items loaded significantly on the general factor, and most items also had moderate to large loadings on specific factors. The correlation between coping styles and self-efficacy and the correlation among different coping styles changed significantly after extracting the general factor of coping stress using bifactor analysis. This was seen in changes from positive (r = 0.714, pcoping styles have a bifactor structure. They also provide direct evidence of coexisting coping resources and styles. This further clarifies that dimensions of coping styles should include coping resources and specific coping styles. This finding has implications for measurement of coping mechanisms, health maintenance, and stress reduction. PMID:24787952

    2015-06-01

    The main purpose of this study was to identify the longitudinal association between specific parenting styles (authoritarian, authoritative, permissive, and neglectful) and adolescent disordered eating behaviors. The current study uses longitudinal data from a 5-year study to examine the associations between parenting style and disordered eating behaviors among adolescents. Data from adolescents (n = 2516) participating in Project EAT (Eating Among Teens), a population-based study from 31 Minnesota schools, were used in the analysis. Time 1 data were collected using in-class assessments of adolescents from Minneapolis/St. Paul schools, and Time 2 data were collected using mailed surveys 5 years later. General Linear Models were used to predict adolescent-reported disordered eating behaviors at Time 2 from adolescent-reported parenting style at Time 1. Adolescent boys and girls who had authoritarian mothers at Time 1 had a higher probability of extreme weight control behaviors 5 years later compared to adolescents with authoritative, permissive, or neglectful mothers. Adolescent girls with authoritarian mothers at Time 1 had a higher probability of engaging in binge-eating behaviors at Time 2 compared to adolescent girls with authoritative or permissive mothers. There were no significant associations between paternal parenting style and adolescent disordered eating behaviors. Although authoritarian parenting style served as a possible risk factor for disordered eating behaviors in adolescents, the findings were not conclusive. Future studies should investigate further the association between parenting style and weight control behaviors in adolescents.

  10. Linking Learning Styles and Learning on Mobile Facebook

    Yu-ching Chen

    2015-04-01

    Full Text Available With continued development of related technologies, Web 2.0 has become an important site of learning innovation. In particular, social networking sites such as Facebook, which have become popular, have the potential to function as an educational tool enabling peer feedback, interaction, and learning in a social context. Preparing appropriate environments for learners with different needs is essential to learning in general and online learning in particular. Yet, in order to create such learning environments, educators must understand differences in students’ learning styles. Although some research focuses on the effects of individual differences such as age and gender on the use of social networking sites, experimental research related to students’ learning styles is still limited. This study used Kolb’s Learning Style Model to investigate differences in student learning outcomes and satisfaction using mobile Facebook for learning, according to learning style. Results showed that participants with “Assimilating” and “Diverging” learning styles performed better than those with “Accomodating” and “Converging” learning styles did and had higher self-efficacy, observational modelling and habit strength toward learning in mobile Facebook. The paper also makes suggestions for integrating mobile Facebook into class and recommendations for future research.

    Individuals with an optimistic explanatory style have generally been linked with improved mental and physical health across a variety of chronic and serious conditions. The purpose of the current study was to examine the effects of explanatory style on recovery time and number of sport-related concussions suffered in the last 12 months. University varsity athletes (n=170) suffering from at least one concussion over the last 12 months from six contact or collision team sports completed both the Attributional Style Questionnaire and the Sport History Questionnaire. The results indicated that athletes with an optimistic explanatory style took longer to recover than athletes with a pessimistic or average explanatory style. More specifically, optimistic athletes who suffered a complex concussion (requiring more than 7 days to recover) took significantly longer to return to play. However, the results showed that explanatory style did not influence whether an athlete suffered subsequent concussions. Overall, the current results can be used to better understand the psychology of concussions, as well as concussion prevention efforts and management strategies.

    The large-scale pattern of subglacial groundwater flow beneath European ice sheets was analysed in a previous report. It was based on a two-dimensional flowline model. In this report, the analysis is extended to three dimensions by exploring the interactions between groundwater and tunnel flow. A theory is developed which suggests that the large-scale geometry of the hydraulic system beneath an ice sheet is a coupled, self-organising system. In this system the pressure distribution along tunnels is a function of discharge derived from basal meltwater delivered to tunnels by groundwater flow, and the pressure along tunnels itself sets the base pressure which determines the geometry of catchments and flow towards the tunnel. The large-scale geometry of tunnel distribution is a product of the pattern of basal meltwater production and the transmissive properties of the bed. The tunnel discharge from the ice margin of the glacier, its seasonal fluctuation and the sedimentary characteristics of eskers are largely determined by the discharge of surface meltwater which penetrates to the bed in the terminal zone. The theory explains many of the characteristics of esker systems and can account for tunnel valleys. It is concluded that the large-scale hydraulic regime beneath ice sheets is largely a consequence of groundwater/tunnel flow interactions and that it is essential similar to non-glacial hydraulic regimes. Experimental data from an Icelandic glacier, which demonstrates measured relationships between subglacial tunnel flow and groundwater flow during the transition from summer to winter seasons for a modern glacier, and which support the general conclusions of the theory is summarised in an appendix.

    Magnetic reconnection in current sheets has relevance to Earth's magnetosphere, solar flares, high-energy astrophysics (pulsar wind nebula (e.g. Crab Nebula), gamma-ray bursts, black hole jets), and laboratory plasma/fusion. Data are shown for several cases with varying values of configuration energy Ec and β. Several conclusions were drawn: Depending on the “configuration energy”, the formation, shape, and lifetime of current sheets can vary. Plasma condition (configuration, β, driving, etc.) strongly affect the efficiency of particle acceleration. For low β and general “configuration energy”, particle heating is expected. For low β, large and long-lived current sheets, it is possible to produce highly non-thermal particles via collisionless plasmoid reconnection.

    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.

    Warm forming has previously proven to be a promising manufacturing route to improve formability of Al brazing sheets used in automotive heat exchanger production; however, the impact of warm forming on subsequent brazing has not previously been studied. In particular, the interaction between liquid clad and solid core alloys during brazing through the process of liquid film migration (LFM) requires further understanding. Al brazing sheet comprised of an AA3003 core and AA4045 clad alloy, supplied in O and H24 tempers, was stretched between 0 and 12 pct strain, at room temperature and 523K (250 °C), to simulate warm forming. Brazeability was predicted through thermal and microstructure analysis. The rate of solid-liquid interactions was quantified using thermal analysis, while microstructure analysis was used to investigate the opposing processes of LFM and core alloy recrystallization during brazing. In general, liquid clad was consumed relatively rapidly and LFM occurred in forming conditions where the core alloy did not recrystallize during brazing. The results showed that warm forming could potentially impair brazeability of O temper sheet by extending the regime over which LFM occurs during brazing. No change in microstructure or thermal data was found for H24 sheet when the forming temperature was increased, and thus warm forming was not predicted to adversely affect the brazing performance of H24 sheet.

    "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

  17. Hybrid Piezoelectric/Fiber-Optic Sensor Sheets

    2004-01-01

    Hybrid piezoelectric/fiber-optic (HyPFO) sensor sheets are undergoing development. They are intended for use in nondestructive evaluation and long-term monitoring of the integrity of diverse structures, including aerospace, aeronautical, automotive, and large stationary ones. It is anticipated that the further development and subsequent commercialization of the HyPFO sensor systems will lead to economic benefits in the form of increased safety, reduction of life-cycle costs through real-time structural monitoring, increased structural reliability, reduction of maintenance costs, and increased readiness for service. The concept of a HyPFO sensor sheet is a generalization of the concept of a SMART Layer(TradeMark), which is a patented device that comprises a thin dielectric film containing an embedded network of distributed piezoelectric actuator/sensors. Such a device can be mounted on the surface of a metallic structure or embedded inside a composite-material structure during fabrication of the structure. There is has been substantial interest in incorporating sensors other than piezoelectric ones into SMART Layer(TradeMark) networks: in particular, because of the popularity of the use of fiber-optic sensors for monitoring the "health" of structures in recent years, it was decided to incorporate fiber-optic sensors, giving rise to the concept of HyPFO devices.

    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.

    Moul, Caroline; Dadds, Mark R

    2013-02-01

    In accordance with a recently proposed account of amygdala function in psychopathy, it is hypothesized that people with high levels of psychopathic personality traits have a bias in learning style to encode the general valence, and neglect the specific-features, of an outcome. We present a novel learning task designed to operationalize these biases in learning style. The results from pilot samples of healthy adults and children and from a clinical sample of children with conduct problems provide support for the validity of the learning task as a measure of learning style and demonstrate a significant relationship between general-valence style learning and psychopathic personality traits. It is suggested that this relationship may be important for the aetiology of the social-cognitive deficits exhibited by psychopaths. These preliminary results suggest that this measure of learning style has the potential to be utilized as a research tool and may assist with the early identification, and treatment, of children with conduct problems and high levels of callous-unemotional traits.

    The Accreditation Council for Graduate Medical Education instituted the 80-h workweek for residency programs in 2003. This presented a unique challenge for surgery residents who must acquire a medical and technical knowledge base during training. Therefore, learning should be delivered in an environment congruent with an individual's learning style. In this study, we evaluated the learning styles of general surgery residents to determine how learning styles changed after the implementation to the 80-h workweek. Kolb learning style inventory was taken by general surgery residents at the University of Cincinnati's Department of Surgery, and results from 1999-2012 were analyzed. Statistical analysis was performed using the chi-squared, logistic regression and Wilcoxon rank-sum test. Significance was defined as a P value of learning styles after the institution of the 80-h workweek to converging (43.9%) and accommodating (40.4%, P learning. This change paralleled the transition to a more team-based approach to patient care with the implementation of the 80-h workweek. These findings are important for surgical educators to consider in the development of surgical resident curriculum. Copyright © 2016 Elsevier Inc. All rights reserved.

    Introduction 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. Methods 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. Results 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. Conclusion 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

  7. Evidence-Based Higher Education - Is the Learning Styles 'Myth' Important?

    Newton, Philip M; Miah, Mahallad

    2017-01-01

    The basic idea behind the use of 'Learning Styles' is that learners can be categorized into one or more 'styles' (e.g., Visual, Auditory, Converger) and that teaching students according to their style will result in improved learning. This idea has been repeatedly tested and there is currently no evidence to support it. Despite this, belief in the use of Learning Styles appears to be widespread amongst schoolteachers and persists in the research literature. This mismatch between evidence and practice has provoked controversy, and some have labeled Learning Styles a 'myth.' In this study, we used a survey of academics in UK Higher Education ( n = 114) to try and go beyond the controversy by quantifying belief and, crucially, actual use of Learning Styles. We also attempted to understand how academics view the potential harms associated with the use of Learning Styles. We found that general belief in the use of Learning Styles was high (58%), but lower than in similar previous studies, continuing an overall downward trend in recent years. Critically the percentage of respondents who reported actually using Learning Styles (33%) was much lower than those who reported believing in their use. Far more reported using a number of techniques that are demonstrably evidence-based. Academics agreed with all the posited weaknesses and harms of Learning Styles theory, agreeing most strongly that the basic theory of Learning Styles is conceptually flawed. However, a substantial number of participants (32%) stated that they would continue to use Learning Styles despite being presented with the lack of an evidence base to support them, suggesting that 'debunking' Learning Styles may not be effective. We argue that the interests of all may be better served by promoting evidence-based approaches to Higher Education.

    Identifying learning styles of acquired brain injury (ABI) patients may aid the learning process by tailoring to the patient's learning needs and preferences. Currently, there is no learning style instrument for ABI patients. We therefore determined the validity and feasibility of the Adapted Learning Style Inventory (A-LSI) for patients with ABI. We included 99 patients with ABI and 42 healthy controls. Learning styles were determined and subgroups were used to evaluate the validity of the A-LSI. Furthermore, rehabilitation professionals' perceptions on learning style and the A-LSI were evaluated. In the patient group, the A-LSI yielded the following learning styles: 4 doers, 54 observers, 2 deciders and 39 thinkers. A similar distribution was found for the control group (3, 28, 0 and 11, respectively). Spearman correlations revealed moderate internal validity. Content validity of the A-LSI was also moderate; 11 out of 19 patients recognized themselves in their A-LSI learning style. Furthermore, 12 rehabilitation professionals reported positive and negative aspects of the A-LSI and suggestions for using learning style in rehabilitation. Rehabilitation professionals were generally positive about using learning style in ABI rehabilitation. This study, however, raises doubts about the validity and feasibility of the A-LSI for this population. Rehabilitation professionals are generally positive about the assessment and implementation of learning style in rehabilitation. The A-LSI seems to be an inappropriate learning style instrument for individuals with ABI. There is a need for a more practical instrument to assess learning style directly at start of rehabilitation.

    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.

    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.

    2017-03-01

    We study the Casimir friction phenomenon in a system consisting of two flat, infinite, and parallel graphene sheets, which are coupled to the vacuum electromagnetic (EM) field. Those couplings are implemented, in the description we use, by means of specific terms in the effective action for the EM field. They incorporate the distinctive properties of graphene, as well as the relative sliding motion of the sheets. Based on this description, we evaluate two observables due to the same physical effect: the probability of vacuum decay and the frictional force. The system exhibits a threshold for frictional effects; namely, they only exist if the speed of the sliding motion is larger than the Fermi velocity of the charge carriers in graphene.

    2017-11-01

    The classical spinning particles are considered such that quantization of classical model leads to an irreducible massive representation of the Poincaré group. The class of gauge equivalent classical particle world lines is shown to form a [(d +1 )/2 ]-dimensional world sheet in d -dimensional Minkowski space, irrespectively to any specifics of the classical model. For massive spinning particles in d =3 , 4, the world sheets are shown to be circular cylinders. The radius of the cylinder is fixed by representation. In higher dimensions, the particle's world sheet turns out to be a toroidal cylinder R ×TD, D =[(d -1 )/2 ]. Proceeding from the fact that the world lines of irreducible classical spinning particles are cylindrical curves, while all the lines are gauge equivalent on the same world sheet, we suggest a method to deduce the classical equations of motion for particles and also to find their gauge symmetries. In d =3 Minkowski space, the spinning particle path is defined by a single fourth-order differential equation having two zero-order gauge symmetries. The equation defines the particle's path in Minkowski space, and it does not involve auxiliary variables. A special case is also considered of cylindric null curves, which are defined by a different system of equations. It is shown that the cylindric null curves also correspond to irreducible massive spinning particles. For the higher-derivative equation of motion of the irreducible massive spinning particle, we deduce the equivalent second-order formulation involving an auxiliary variable. The second-order formulation agrees with a previously known spinning particle model.

    The two original versions of ‘invisibility’ cloaks (Leonhardt 2006 Science 312 1777-80 and Pendry et al 2006 Science 312 1780-2) show perfect cloaking but require unphysical singularities in material properties. A non-Euclidean version of cloaking (Leonhardt 2009 Science 323 110-12) was later presented to address these problems, using a very complicated non-Euclidean geometry. In this work, we combine the two original approaches to transformation optics into a more general concept: transformation optics with artificial Riemann sheets. Our method is straightforward and can be utilized to design new kinds of cloaks that can work not only in the realm of geometric optics but also using wave optics. The physics behind this design is similar to that of the conformal cloak for waves. The resonances in the interior region make the phase delay disappear and induce the cloaking effect. Numerical simulations confirm our theoretical results.

    To assess dentist-assistant interaction and communication styles and their associated factors in Jordan. Three different areas in Amman where private dental clinics heavily cluster were chosen. The researcher visited all dental clinics in these areas and invited dentists to participate in this study. A structured self-administered questionnaire was designed and included the 22 items on staff communication that were used by Gorter and Freeman to assess communication styles. The culturally adapted items were analysed in such a way to reflect the structure that is used in the original study. There was a significant interaction between dentist's gender and communication styles (F = 3.8, P = 0.022). The only significant difference between men and women was for professional leadership style (P = 0.011) where men were more likely to adopt professional leadership style than women. For men, the average score for friendly leadership style was significantly lower than that for other styles. For women, the average score was the highest for gender interacting style which was significantly higher than that for friendly leadership style and professional interacting style, but not business leadership style. Communication and interaction styles between Jordanian dentists and their assistants differ according to gender. Jordanian dentists are less likely to adopt friendly leadership communication style compared with other styles.

  5. Monitoring Antarctic ice sheet surface melting with TIMESAT algorithm

    2011-12-01

    Antarctic ice sheet contributes significantly to the global heat budget by controlling the exchange of heat, moisture, and momentum at the surface-atmosphere interface, which directly influence the global atmospheric circulation and climate change. Ice sheet melting will cause snow humidity increase, which will accelerate the disintegration and movement of ice sheet. As a result, detecting Antarctic ice sheet melting is essential for global climate change research. In the past decades, various methods have been proposed for extracting snowmelt information from multi-channel satellite passive microwave data. Some methods are based on brightness temperature values or a composite index of them, and others are based on edge detection. TIMESAT (Time-series of Satellite sensor data) is an algorithm for extracting seasonality information from time-series of satellite sensor data. With TIMESAT long-time series brightness temperature (SSM/I 19H) is simulated by Double Logistic function. Snow is classified to wet and dry snow with generalized Gaussian model. The results were compared with those from a wavelet algorithm. On this basis, Antarctic automatic weather station data were used for ground verification. It shows that this algorithm is effective in ice sheet melting detection. The spatial distribution of melting areas(Fig.1) shows that, the majority of melting areas are located on the edge of Antarctic ice shelf region. It is affected by land cover type, surface elevation and geographic location (latitude). In addition, the Antarctic ice sheet melting varies with seasons. It is particularly acute in summer, peaking at December and January, staying low in March. In summary, from 1988 to 2008, Ross Ice Shelf and Ronnie Ice Shelf have the greatest interannual variability in amount of melting, which largely determines the overall interannual variability in Antarctica. Other regions, especially Larsen Ice Shelf and Wilkins Ice Shelf, which is in the Antarctic Peninsula

To an extent never envisaged at the time, this reconstruction has been used by groups worldwide as boundary-condition input for general circulation models (GCMs) and other numerical experiments to reconstruct glacial-maximum atmospheric and oceanic circulation. Other GCM experiments based on rough approximations of ice-sheet size through the deglacial interval also have been run [Kutzbach and Guetter, 1986], and the climatic output has in turn been compared against ground-truth data such as vegetation and lake levels [COHMAP, 1988].Recently, several results have provided fresh impetus for updating the CLIMAP reconstruction: coral reef data [Fairbanks, 1989] placing sea level near -120 m at the last glacial maximum at Barbados, which also provide a deglacial record of sea level; U-series dates on these corals [Bard et al., 1990] showing that 14C chronologies are anomalously young through the deglaciation, which place the last glacial maximum at 21,000-20,000 years ago; major improvements [Tushingham and Peltier, 1991] in iteratively matching hypothesized ice-sheet thickness histories based on an independent model of the Earth's visco-elasticity to radiometrically dated sea-level rebound histories; and glacial and marine geological fieldwork by many scientists. These findings provide significant new constraints on the past size of the ice sheets at the last glacial maximum and throughout deglaciation. As an added impetus, the NATO Paleoclimate Modeling Intercomparison Project (PMIP) has called for an updated reconstruction of glacial-maximum ice sheets. Their objective is to compare the performance of GCMs when tested on a realistic (glacial) world having ice-sheet boundary conditions very different from today's.

    Rassool, Goolam Hussein; Rawaf, Salman

    To determine the predominant learning style preferences of undergraduate nursing students. A demographic questionnaire and Honey and Mumford's (2000a) learning styles questionnaire were administered to a purposive sample of 136 students. A response rate of 81% (110) was obtained. The results are congruent with U.K. studies, which show that the reflector is the preferred learning style of undergraduate nursing students. A 'dual' learning style category was also identified. A mismatch between teaching style and the learning styles of students has been found to have serious consequences. A variety of modes of teaching and learning should be used to meet the learning needs of students.

    Bacteria have robust responses to a variety of stresses. In particular, bacteria like Escherichia coli have multiple cell envelope stress responses, and generally we evaluate what these responses are doing by the repair systems they induce. However, probably at least as important in interpreting what is being sensed as stress are the genes that these stress systems downregulate, directly or indirectly. This is discussed here for the Cpx and sigma E systems of E. coli. Copyright © 2017 American Society for Microbiology.

    Dysfunctional parenting styles represent a risk factor for the development of psychological disturbances. The present study investigated the differential validity of the German language Fragebogen zur Erfassung dysfunktionaler Erziehungsstile (FDEB; Measurement of Parental Styles, MOPS) and determined whether different forms of psychological disorders are associated with specific patterns of parenting styles. 145 inpatients, 108 outpatients and a control group of 633 representative individuals from the general population were investigated by adapting the FDEB. A comparison of dysfunctional parenting styles showed different distress levels within the diagnostic groups: Patients suffering from depression reported high levels of maternal indifference and over protectiveness together with an abusive rearing behavior on the part of both parents. Patients with anxiety disorders reported having overprotective mothers. Bulimic patients as well as those with personality disorders significantly exhibited stress in almost all areas. However, anorexic patients did not differ significantly from the control group, which appeared to be the least affected of all. The FDEB showed a satisfactory differential validity. There was evidence that specific patterns of dysfunctional parenting styles were associated with different diagnostic groups.

    2016-03-01

    Full Text Available Purpose: This study was of a theoretical character and aimed at presenting various descriptions of the interactions between all possible pairs of four well-known negotiating styles dependent on personality traits. Methodology: This study was based on analysis of the interactions as well as authors’ experiences from their observations and analyses on human behaviors during numerous negotiations and roleplay exercises arranged at the courses for practitioners. The stress was put on analyzing the interactions occurring between people representing both different and the same negotiating styles. Findings: The attempt at describing such interactions was successful and promising for farther research. The concept constitutes a useful tool for analyzing human behavioral aspects of different types of business negotiations, within the process of their planning, conduct and evaluation. Nevertheless, the concept will be a subject of subsequent authors’ research, focusing on its improvement mainly by searching more precise features of negotiating styles and interactions between them. Practical implications: The concept can be applied to analyze many real negotiation situations as well as within the experiment to be arranged by the authors to examine those interactions within the hundreds of pairs of negotiators solving particular case studies. Thus the description of such interactions can be treated as a specifc hypothesis. Originality: In general, the suggestion for solving complex, diffcult and essential issues of negotiating styles was presented but was rarely investigated in the literature on negotiations. In particular, an original concept of describing the interactions between those styles was suggested,.

    Full Text Available Abstract Background Patient-provider relationships in primary care are characterized by greater continuity and depth than in non-primary care specialties. We hypothesized that relationship styles of medical students based on attachment theory are associated with specialty choice factors and that such factors will mediate the association between relationship style and ultimately matching in a primary care specialty. Methods We determined the relationship styles, demographic characteristics and resident specialty match of 106 fourth-year medical students. We assessed the associations between 1 relationship style and specialty choice factors; 2 specialty choice factors and specialty match, and 3 relationship style and specialty match. We also conducted mediation analyses to determine if factors examined in a specialty choice questionnaire mediate the association between relationship style and ultimately matching in a primary care specialty. Results Prevalence of attachment styles was similar to that found in the general population and other medical school settings with 59% of students rating themselves as having a secure relationship style. Patient centeredness was directly associated, and career rewards inversely associated with matching in a primary care specialty. Students with a self-reliant relationship style were significantly more likely to match in a non-primary care specialty as compared to students with secure relationship style (OR = 5.3, 95% CI 1.8, 15.6. There was full mediation of the association between relationship style and specialty match by the specialty choice factor characterized by patient centeredness. Conclusion Assessing relationship styles based on attachment theory may be a potentially useful way to improve understanding and counsel medical students about specialty choice.

  15. THE FREE-FALL TIME OF FINITE SHEETS AND FILAMENTS

    Molecular clouds often exhibit filamentary or sheet-like shapes. We compute the free-fall time ({tau}{sub ff}) for finite, uniform, self-gravitating circular sheets and filamentary clouds of small but finite thickness, so that their volume density {rho} can still be defined. We find that, for thin sheets, the free-fall time is larger than that of a uniform sphere with the same volume density by a factor proportional to {radical}A, where the aspect ratio A is given by A = R/h, R being the sheet's radius and h is its thickness. For filamentary clouds, the aspect ratio is defined as A=L/R, where L is the filament's half-length and R is its (small) radius, and the modification factor is more complicated, although in the limit of large A it again reduces to nearly {radical}A. We propose that our result for filamentary shapes naturally explains the ubiquitous configuration of clumps fed by filaments observed in the densest structures of molecular clouds. Also, the longer free-fall times for non-spherical geometries in general may contribute toward partially alleviating the 'star formation conundrum', namely, the star formation rate in the Galaxy appears to be proceeding in a timescale much larger than the total molecular mass in the Galaxy divided by its typical free-fall time. If molecular clouds are in general formed by thin sheets and long filaments, then their relevant free-fall time may have been systematically underestimated, possibly by factors of up to one order of magnitude.

    Assessors are the main measurement instruments in subjective quality evaluation studies. Although the perceptual abilities and constrains are influenced by multiple demographic and psychographic factors, they are typically disregarded as a part of quality assessment. Cognitive styles refer to individual's consistent approaches to organize and represent information. Goal of this study is to explore the impact of cognitive styles on visual quality requirements. The data collection is conducted using the Style of Processing (SOP) questionnaire in three video quality experiments with a total of 72 participants. All participants were categorized into four groups according to sensorial preferences in information processing (visual, verbal, bimodal - high processing, and bimodal - low processing). The experiments were conducted in controlled circumstances when varying depth in video quality with several content types on the mobile device. The results show variation in quality requirements between these groups. Finally, these results also indicate that sensorial processing styles are essential to explore for sample characterization in quality evaluation experiments and for exploring more user-aware quality adjustments in future services and products.

  9. Theoretical analysis of sheet metal formability

    Science.gov (United States)

    Zhu, Xinhai

    Sheet metal forming processes are among the most important metal-working operations. These processes account for a sizable proportion of manufactured goods made in industrialized countries each year. Furthermore, to reduce the cost and increase the performance of manufactured products, in addition to the environmental concern, more and more light weight and high strength materials have been used as a substitute to the conventional steel. These materials usually have limited formability, thus, a thorough understanding of the deformation processes and the factors limiting the forming of sound parts is important, not only from a scientific or engineering viewpoint, but also from an economic point of view. An extensive review of previous studies pertaining to theoretical analyses of Forming Limit Diagrams (FLDs) is contained in Chapter I. A numerical model to analyze the neck evolution process is outlined in Chapter II. With the use of strain gradient theory, the effect of initial defect profile on the necking process is analyzed. In the third chapter, the method proposed by Storen and Rice is adopted to analyze the initiation of localized neck and predict the corresponding FLDs. In view of the fact that the width of the localized neck is narrow, the deformation inside the neck region is constrained by the material in the neighboring homogeneous region. The relative rotation effect may then be assumed to be small and is thus neglected. In Chapter IV, Hill's 1948 yield criterion and strain gradient theory are employed to obtain FLDs, for planar anisotropic sheet materials by using bifurcation analysis. The effects of the strain gradient coefficient c and the material anisotropic parameters R's on the orientation of the neck and FLDs are analyzed in a systematic manner and compared with experiments. In Chapter V, Hill's 79 non-quadratic yield criterion with a deformation theory of plasticity is used along with bifurcation analyses to derive a general analytical

    As a first qualitative assessment tool, LOVECLIM has been used to investigate the interactions between insolation, ice sheets and the East Asian Monsoon at the Marine Isotopic Stage 13 (MIS-13) in work by Yin et al. (Clim Past 4:79-90, 2008, Clim Past 5:229-243, 2009). The results are in need of validation with a more sophisticated model, which is done in this work with the ARPEGE atmospheric general circulation model. As in the Earth system Model of Intermediate Complexity, LOVECLIM, ARPEGE shows that the northern hemispheric high insolation in summer leads to strong MIS-13 monsoon precipitation. Data from the Chinese Loess Plateau indicate that MIS-13 was locally a warm and humid period (Guo et al. in Clim Past 5:21-31, 2009; Yin and Guo in Chin Sci Bull 51(2):213-220, 2006). This is confirmed by these General Circulation Model (GCM) results, where the MIS-13 climate is found to be hotter and more humid both in the presence and absence of any added ice sheets. LOVECLIM found that the combined effects of the ice sheets and their accompanying SSTs contribute to more precipitation in eastern China, whilst in ARPEGE the impact is significant in northeastern China. Nonetheless the results of ARPEGE confirm the counter-intuitive results of LOVECLIM where ice sheets contribute to enhance monsoon precipitation. This happens through a topography induced wave propagating through Eurasia with an ascending branch over northeastern China. A feature which is also seen in LOVECLIM. The SST forcing in ARPEGE results in a strong zonal temperature gradient between the North Atlantic and east Eurasia, which in turn triggers an atmospheric gravity wave. This wave induces a blocking Okhotskian high, preventing the northwards penetration of the Meiyu monsoon front. The synergism between the ice sheets and SST is found through the factor separation method, yielding an increase in the Meiyu precipitation, though a reduction of the Changma precipitation. The synergism between the ice

    Full Text Available Background: Learning styles are cognitive, emotional, and physiological traits, as well as indicators of how learners perceive, interact, and respond to their learning environments. According to Honey-Mumford, learning styles are classified as active, reflexive, theoretical, and pragmatic. Objective: The purpose of this study was to identify the predominant learning styles among pharmacy students at the Federal University of Paraná, Brazil. Methods: An observational, cross-sectional, and descriptive study was conducted using the Honey-Alonso Learning Style Questionnaire. Students in the Bachelor of Pharmacy program were invited to participate in this study. The questionnaire comprised 80 randomized questions, 20 for each of the four learning styles. The maximum possible score was 20 points for each learning style, and cumulative scores indicated the predominant learning styles among the participants. Honey-Mumford (1986 proposed five preference levels for each style (very low, low, moderate, high, and very high, called a general interpretation scale, to avoid student identification with one learning style and ignoring the characteristics of the other styles. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS version 20.0.

    Background: Learning styles are cognitive, emotional, and physiological traits, as well as indicators of how learners perceive, interact, and respond to their learning environments. According to Honey-Mumford, learning styles are classified as active, reflexive, theoretical, and pragmatic. Objective: The purpose of this study was to identify the predominant learning styles among pharmacy students at the Federal University of Paraná, Brazil. Methods: An observational, cross-sectional, and descriptive study was conducted using the Honey-Alonso Learning Style Questionnaire. Students in the Bachelor of Pharmacy program were invited to participate in this study. The questionnaire comprised 80 randomized questions, 20 for each of the four learning styles. The maximum possible score was 20 points for each learning style, and cumulative scores indicated the predominant learning styles among the participants. Honey-Mumford (1986) proposed five preference levels for each style (very low, low, moderate, high, and very high), called a general interpretation scale, to avoid student identification with one learning style and ignoring the characteristics of the other styles. Statistical analysis was performed using the Statistical Package for the Social Sciences (SPSS) version 20.0.

    The development of confocal microscopy techniques introduced the ability to optically section fluorescent samples in the axial dimension, perpendicular to the image plane. These approaches, via the placement of a pinhole in the conjugate image plane, provided superior resolution in the axial (z) dimension resulting in nearly isotropic optical sections. However, increased axial resolution, via pinhole optics, comes at the cost of both speed and excitation efficiency. Light sheet fluorescent microscopy (LSFM), a century-old idea made possible with modern developments in both excitation and detection optics, provides sub-cellular resolution and optical sectioning capabilities without compromising speed or excitation efficiency. Over the past decade, several variations of LSFM have been implemented each with its own benefits and deficiencies. Here we discuss LSFM fundamentals and outline the basic principles of several major light-sheet-based imaging modalities (SPIM, inverted SPIM, multi-view SPIM, Bessel beam SPIM, and stimulated emission depletion SPIM) while considering their biological relevance in terms of intrusiveness, temporal resolution, and sample requirements.

    Full Text Available Using sheet-bulk metal forming processes the application of bulk forming operations on sheet metals enables the manufacturing of functional components with local wall thickness variations. As these processes come along with a two- and three-dimensional material flow, the control of the material flow is crucial for ensuring a proper filling of functional elements and thus ensuring the components quality. Controlling the material flow can be achieved by different solutions: the local adaption of tribological conditions and the application of process adapted semi-finished parts. In this paper, both solutions as well as their general qualification in two sheet-bulk metal forming processes are presented.

    In the stamping of automotive parts, friction and lubrication play a key role in achieving high quality products. In the development process of new automotive parts, it is therefore crucial to accurately account for these effects in sheet metal forming simulations. This paper presents a selection of results considering friction and lubrication modelling in sheet metal forming simulations of a front fender product. For varying lubrication conditions, the front fender can either show wrinkling or fractures. The front fender is modelled using different lubrication amounts, tool roughness’s and sheet coatings to show the strong influence of friction on both part quality and the overall production stability. For this purpose, the TriboForm software is used in combination with the AutoForm software. The results demonstrate that the TriboForm software enables the simulation of friction behaviour for varying lubrication conditions, i.e. resulting in a generally applicable approach for friction characterization under industrial sheet metal forming process conditions.

We also find that male CEOs pay themselves more after fathering a child, especially after fathering a son....... These results are consistent with a desire by the CEO to husband more resources for his family after fathering a child and the psychological priming of the CEO’s generosity after the birth of his first daughter and specifically toward women after the birth of his first child of either gender....

    This study examined the psychometric properties of the Defense Style Questionnaire (DSQ-40) in adolescents. Internal consistency, factor structure, and discriminant and concurrent validity of the DSQ-40 were studied in 211 adolescent psychiatric outpatients aged 13 to 19 years and 199 age-matched and sex-matched controls. Principal components analysis yielded four internally consistent components: mature, neurotic, image-distorting, and immature defense styles. The outpatients reported more immature, image-distorting, and neurotic styles and less mature style than did the controls, suggesting adequate discriminant validity. As a demonstration of convergent and concurrent validity, the severity of psychiatric symptoms assessed by the General Health Questionnaire and psychosocial adjustment assessed by the Global Assessment of Functioning Scale correlated theoretically meaningfully with the different defense styles. The DSQ-40 appears to be a reliable and valid instrument for adolescents.

    An important tool in the field of metamaterials is the extraction of effective material parameters from simulated or measured scattering parameters of a sample. Here we discuss a retrieval method for thin-film structures that can be approximated by a two-dimensional scattering sheet. We determine the effective sheet conductivity from the scattering parameters and we point out the importance of the magnetic sheet current to avoid an overdetermined inversion problem. Subsequently, we present two applications of the sheet retrieval method. First, we determine the effective sheet conductivity of thin silver films and we compare the resulting conductivities with the sheet conductivity of graphene. Second, we apply the method to a cut-wire metamaterial with an electric dipole resonance. The method is valid for thin-film structures such as two-dimensional metamaterials and frequency-selective surfaces and can be easily generalized for anisotropic or chiral media.

  20. Triggering of explosive reconnection in a thick current sheet via current sheet compression: Less current sheet thinning, more temperature anisotropy

    Two-dimensional kinetic simulations of compression of thick current sheets are performed to see how it can lead to triggering of explosive magnetic reconnection. The current sheet under study is simply in a Harris-like anti-paralell and symmetric geometry. A one-dimensional pre-study shows that the compression is more effective to make the plasma anisotropy than to thin the current sheet width. When the lobe magnetic field is amplified by a factor of 2, the plasma temperature anisotropy inside the current sheet reaches 2 but the current sheet thickness is reduced only by 1/sqrt(2). If a current sheet thickness needs to be comparable to the ion inertial scale for reconnection triggering take place, as is widely and frequently mentioned in the research community, the initial thickness cannot be more than a few ion scale for reconnection to set-in. On the other hand, the temperature anisotropy of 2 can be significant for the triggering problem. Two-dimensional simulations show explosive magnetic reconnection to take place even when the initial current sheet thickness more than an order of magnitude thicker than the ion scale, indicating the resilient triggering drive supplied by the temperature anisotropy. We also discuss how the reconnection triggering capability of the temperature anisotropy boosted tearing mode for thick current sheets compares with the instabilities in the plane orthogonal to the reconnecting field.

  3. Evidence-Based Higher Education – Is the Learning Styles ‘Myth’ Important?

    Science.gov (United States)

    Newton, Philip M.; Miah, Mahallad

    2017-01-01

    The basic idea behind the use of ‘Learning Styles’ is that learners can be categorized into one or more ‘styles’ (e.g., Visual, Auditory, Converger) and that teaching students according to their style will result in improved learning. This idea has been repeatedly tested and there is currently no evidence to support it. Despite this, belief in the use of Learning Styles appears to be widespread amongst schoolteachers and persists in the research literature. This mismatch between evidence and practice has provoked controversy, and some have labeled Learning Styles a ‘myth.’ In this study, we used a survey of academics in UK Higher Education (n = 114) to try and go beyond the controversy by quantifying belief and, crucially, actual use of Learning Styles. We also attempted to understand how academics view the potential harms associated with the use of Learning Styles. We found that general belief in the use of Learning Styles was high (58%), but lower than in similar previous studies, continuing an overall downward trend in recent years. Critically the percentage of respondents who reported actually using Learning Styles (33%) was much lower than those who reported believing in their use. Far more reported using a number of techniques that are demonstrably evidence-based. Academics agreed with all the posited weaknesses and harms of Learning Styles theory, agreeing most strongly that the basic theory of Learning Styles is conceptually flawed. However, a substantial number of participants (32%) stated that they would continue to use Learning Styles despite being presented with the lack of an evidence base to support them, suggesting that ‘debunking’ Learning Styles may not be effective. We argue that the interests of all may be better served by promoting evidence-based approaches to Higher Education. PMID:28396647

    2017-06-01

    The aim of this work is to provide exact analytical closed-form expressions for the longitudinal and transverse optical radiation force and axial spin torque components, for a 2D surface cross-section with arbitrary shape in the field of light-sheet beams of arbitrary wavefront. Generalized partial-wave series expressions for the longitudinal and transverse optical radiation forces and torque are derived based on the multipole expansion in cylindrical wave functions, stemming from series expansions for the incident and scattered electromagnetic fields. The incident light-sheet wavefields are expressed using generalized series involving the beam-shape coefficients (BSCs), and the scattered fields are given in terms of series involving the scattering coefficients of the object. Numerical illustrative examples on a dielectric absorptive circular cylindrical cross-section are provided for different wavefronts, ranging from plane waves, as well as non-paraxial scalar Airy and Gaussian light-sheet beams. The BSCs are derived based on the angular spectrum decomposition method, which provides adequate means to evaluate the radiation force and torque components when the cylinder cross-section is centered on the beam, or shifted off-axially with respect to the incident axis of wave propagation. In essence, the present theoretical analysis provides a complete formalism in the framework of the generalized Lorenz-Mie theory in 2D based upon exact closed-form series expressions to compute the optical force and torque components induced by 2D light-sheets of arbitrary wavefronts, illuminating a scatterer with an arbitrary geometrical cross-section (in 2D). Possible applications are in particle transport and rotation.

  5. Bending Properties of Sandwich Beams with Fiber Metal Laminate Face Sheet

    2013-01-01

    Full Text Available Sandwich structures are widely used in aerospace, high speed trains and marine applications because of lightweight and high in-plane and flexural stiffness. Sandwich structures consist of two thin face sheets and a core. Face sheets usually are made from highly stiff and highly strong materials; In general, the face sheets may be of different metal or composite layers. Both metal and composite face sheets have advantages and disadvantages, and searching for new materials with better properties is in progress. In this paper flexural behavior of a new generation sandwich beams with fiber metal laminate (FML face sheets were investigated experimentally. Three groups of specimens with different layer arrangements of face sheets consist of (Al/GE (0-90/GE(90-0/Al, (Al/GE(0-90/Al/GE(90-0 and (GE(0-90-0-90-90-0-90-0 and 40 kg/m3 polyurethane foam core were made and tested. The results show that sandwich beams with FML face sheets have better resistance against local loads, while composite faces are weak against intense loads. Also, FML faces are lighter than metal face sheets and have better connection to foam core. Also, a simple classical theory was used to predict the force-deflection behaviour of sandwich beams in elastic region. Good agreement between the experimental results and analytical prediction were obtained. Sandwich beams with FML face sheets have larger elastic region than beams with composite face sheets therefore agreement between the analytical and experimental results in these specimens are in larger area.

  6. Influence of ocean model treatment on late Paleozoic ice sheet growth

    Science.gov (United States)

    Tilevitz, C.; Poulsen, C. J.

    2016-12-01

    The late Paleozoic ice age was a period of time 340-250 Ma during which ice sheets grew and shrank across the Gondwanan supercontinent. Atmospheric general circulation models (GCMs) have previously been used to generate late Paleozoic climates suitable for the growth of large ice sheets on the Gondwanan supercontinent to investigate the climate conditions necessary for ice sheet growth. These simulations included a slab ocean with diffusive heat transport that lacks the ability to accurately capture the ocean dynamics of the Paleozoic. In this work, a series of experiments are conducted to investigate the sensitivity of ice sheets to the ocean treatment. Four experiments are conducted: (i) The NCAR Community Earth System Model (CESM)'s fully dynamic ocean is used to explore Permian ice sheet growth under more realistic conditions. (ii)The GENESIS GCM, which uses a slab ocean, is run to directly compare the two ocean models. (iii) The CESM slab ocean model is run using heat fluxes from the CESM simulation. (iv)GENESIS in fixed-SST mode is run using surface temperatures from the CESM simulation. All experiments are conducted for two atmospheric pCO2 concentrations (280 and 560 ppm). Climatologies from this set of experiments are then used to drive the Penn State University three-dimensional ice sheet model (ISM). Our results show that late Paleozoic ice sheets are sensitive to ocean dynamics. The ice sheets that result from both the GENESIS slab and SST cases have volumes of 108 km3 for both CO2 concentrations, and the CESM slab ocean case produced volumes of .5-108 km3 for both cases. The fully dynamic CESM simulation, however, produced ice sheets of 108 km3 for the 280 ppm CO2 case, but only 106 km3 for the 560 ppm CO2 case. This dramatic difference suggests that modeled ice sheets possess a critical sensitivity to pCO2 concentrations in a fully dynamic climate system.

  7. Geomagnetic activity effects on plasma sheet energy conversion

    Directory of Open Access Journals (Sweden)

    M. Hamrin

    2010-10-01

    Full Text Available In this article we use three years (2001, 2002, and 2004 of Cluster plasma sheet data to investigate what happens to localized energy conversion regions (ECRs in the plasma sheet during times of high magnetospheric activity. By examining variations in the power density, E·J, where E is the electric field and J is the current density obtained by Cluster, we have studied the influence on Concentrated Load Regions (CLRs and Concentrated Generator Regions (CGRs from variations in the geomagnetic disturbance level as expressed by the Kp, the AE, and the Dst indices. We find that the ECR occurrence frequency increases during higher magnetospheric activities, and that the ECRs become stronger. This is true both for CLRs and for CGRs, and the localized energy conversion therefore concerns energy conversion in both directions between the particles and the fields in the plasma sheet. A higher geomagnetic activity hence increases the general level of energy conversion in the plasma sheet. Moreover, we have shown that CLRs live longer during magnetically disturbed times, hence converting more electromagnetic energy. The CGR lifetime, on the other hand, seems to be unaffected by the geomagnetic activity level. The evidence for increased energy conversion during geomagnetically disturbed times is most clear for Kp and for AE, but there are also some indications that energy conversion increases during large negative Dst. This is consistent with the plasma sheet magnetically mapping to the auroral zone, and therefore being more tightly coupled to auroral activities and variations in the AE and Kp indices, than to variations in the ring current region as described by the Dst index.

    In India, as in some other neighboring Asian countries, students and teachers are generally unaware of the differences in the learning styles among learners, which can handicap students with learning styles alien to the common teaching/learning modality within the institution. This study aims to find out whether making students aware of their learning styles and then using the Appreciative Inquiry approach to help them discover learning strategies that worked for them and others with similar learning styles within the institution made them perceive that this experience improved their learning and performance in exams. The visual, auditory, read-write, and kinesthetic (VARK) inventory of learning styles questionnaire was administered to all 100 first-year medical students of the Father Muller's Medical College in Mangalore India to make them aware of their individual learning styles. An Appreciate Inquiry intervention was administered to 62 student volunteers who were counseled about the different learning styles and their adaptive strategies. Pre and post intervention change in student's perception about usefulness of knowing learning styles on their learning, learning behavior, and performance in examinations was collected from the students using a prevalidated questionnaire. Post intervention mean scores showed a significant change (P < 0.0001) in student's self-perceptions about usefulness of knowing one's learning style and discovering strategies that worked within the institutional environment. There was agreement among students that the intervention helped them become more confident in learning (84%), facilitating learning in general (100%), and in understanding concepts (100%). However, only 29% of the students agreed that the intervention has brought about their capability improvement in application of learning and 31% felt it improved their performance in exams. Appreciate Inquiry was perceived as useful in helping students discover learning strategies

    Adolescent substance use is an area of concern because early substance use is associated with a higher risk of adverse outcomes. Parenting style, defined as the general style of parenting, as well as substance-specific parenting practices may influence children's substance use behaviour. The present study aims to probe the impact of parenting style on adolescent substance use. A cohort of 1268 adolescents (48% girls), aged 12-13 years at baseline, from 21 junior high schools was assessed in the first semester of junior high school, and then again in the last semester of the 9th grade, 32 months later. Parenting style, operationalised as a fourfold classification of parenting styles, including established risk factors for adolescent substance use, were measured at baseline. Neglectful parenting style was associated with worse substance use outcomes across all substances. After adjusting for other proximal risk factors in multivariate analyses, parenting style was found to be unrelated to substance use outcomes with one exception: authoritative parenting style was associated with less frequent drinking. Association with deviant peers, delinquent behaviour, provision of alcohol by parents, and previous use of other substances were associated with substance use outcomes at follow-up. The results of the present study indicate that parenting style may be less important for adolescent substance use outcomes than what has previously been assumed, and that association with deviant peers and delinquent behaviour may be more important for adolescent substance use outcomes than general parenting style.

    2003-01-01

    This study investigates parenting styles among Chinese fathers in Hong Kong as perceived by their school-age children. Four parenting styles, namely inductive, indulgent, indifferent, and dictatorial parenting, are assessed using the Parent Behavior Report (1988). Data were collected through a questionnaire survey on a sample of 1011 Primary Three to Five Chinese students from six schools in Hong Kong and 471 fathers. Findings show that among Chinese fathers, the least common parenting style is inductive, while the other three styles are of similar occurrence. Chi-square analysis shows no significant association between children's grade level and father's parenting style. However, there is a significant association with gender, with fathers more likely to be perceived as dictatorial with boys and indulgent with girls. The effect of paternal styles on children's school-related performance is also examined. MANOVA results show that significant differences are found among children of the four paternal style groups with respect to academic performance, interest in school work, aspiration for education, involvement in extracurricular activities, and efficacy for self-regulated learning. Post-hoc tests reveal that children's performance is similar between the groups with indulgent and inductive fathers, and between children of indifferent and dictatorial fathers, with the former groups performing better than the latter in general. Findings are discussed with regard to research on parenting style and paternal behavior, as well as understanding the roles of fathers in Chinese families in the socio-cultural context in Hong Kong.

    Cancer patients experience a high level of stress caused by the disease and treatment processes. Dealing with cancer using more beneficial coping styles can effectively improve the quality of life (QOL) and reduce the side effects of cancer, and it is treatment. In this study, we aimed to investigate the relationship between coping styles and QOL in cancer patients. The study was performed on 150 cancer patients (71 females and 79 males) admitted to the hospitals affiliated with Kermanshah University of Medical Sciences. Endler and Parker Coping Inventory for Stressful Situations, and World Health Organization's Quality of Life Questionnaire were used to evaluate their coping style and QOL, respectively. The Present study showed in cancer patients being male, single, having higher salary and education, and lower age are related to higher QOL. Furthermore, in general, QOL of cancer patients was positively correlated with avoidant coping style (P styles (P style, predominantly on an emotion-focused coping style, is essential to improve patient's QOL, and that patients possibly to employ a more emotion-oriented coping style should receive enough notice, particularly before discharge.

    Introduction Cognitive theories of psychopathology have generally proposed that early experiences of childhood abuse and neglect may result in the development of early maladaptive self-schemas. Maladaptive core schemas are central in the development and maintenance of psychological symptoms in a schema-focused approach. Psychosocial dysfunction in individuals with psychological problems has been consistently found to be associated with symptom severity. However, till date, linkages between psychosocial functioning, early traumatic experiences and core schemas have received little attention. The aim of the present study was to explore the relations among maladaptive interpersonal styles, negative experiences in childhood and core self-schemas in non-clinical adults. Methods A total of 300 adults (58% women) participated in the study. The participants completed a socio-demographic questionnaire, Young Schema Questionnaire, Childhood Trauma Questionnaire and Interpersonal Style Scale. Results Hierarchical regression analyses revealed that the Disconnection and Rejection and Impaired Limits schema domains were significant antecedents of maladaptive interpersonal styles after controlling for demographic characteristics and childhood abuse and neglect. Associations of child sexual abuse with Emotionally Avoidant, Manipulative and Abusive interpersonal styles were mediated by early maladaptive schemas. Early maladaptive schemas mediated the relations of emotional abuse with Emotionally Avoidant and Avoidant interpersonal styles as well as the relations of physical abuse with Avoidant and Abusive interpersonal styles. Conclusion Interpersonal styles in adulthood are significantly associated with childhood traumatic experiences. Significant relations between early traumatic experiences and maladaptive interpersonal styles are mediated by early maladaptive schemas. PMID:28360715

    This fact sheet is an overview of the Concentrating Solar Power (CSP) subprogram at the U.S. Department of Energy SunShot Initiative. CSP is a dispatchable, renewable energy option that uses mirrors to focus and concentrate sunlight onto a receiver, from which a heat transfer fluid carries the intense thermal energy to a power block to generate electricity. CSP systems can store solar energy to be used when the sun is not shining. It will help meet the nation’s goal of making solar energy fully cost-competitive with other energy sources by the end of the decade. Worldwide, CSP activity is rapidly scaling, with approximately 10 gigawatts (GW) in various stages of operation or development. In the United States alone, nearly 2 GW of CSP are in operation.

    There is evidence in the literature that adverse early attachment experiences and subsequent attachment insecurities during adulthood would lead to pessimism, low self-esteem, hopelessness and, ultimately, to suicide risk. This paper aims to review finding on the link between attachment style and suicidality. We searched the literature using the database of the U.S. National Center for Biotechnology Information (NCBI)-MedLine/Pubmed system from January 1992 until December 2016. We started with 1992 because, as far as we know, there are no published studies exploring the relationship between suicide and insecure attachment before that year. We considered reports published on the relationship between attachment style and suicidality. We applied several combinations of the following search terms: attachment, adult attachment style and suicidality, suicide, suicidal ideation, suicidal behavior or suicidal thoughts, and suicide attempts. We selected only English language studies. Research suggests that insecure attachment style, mostly anxious, and unresolved traumas are associated with an increased suicide risk. Few studies prospectively examined clinical course, comorbid psychiatric disorders, familial suicidality or other psychosocial factors. Further research is needed to highlight the nature of the link between attachment and suicidality. The presence of suicidal ideation and attempts might be a consequence of an underlying interaction between the emergence of psychiatrics symptoms, and the long-lasting presence of inadequate patterns of attachment. Within this context, Separation Anxiety Disorder, categorized in the DSM-5 as a condition not confined to childhood but as an anxiety disorder that may occur through the entire lifespan, might be the a key for the comprehension of this link. From a neurobiological point of view, the role of oxytocin remains unclear.

    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

    Directory of Open Access Journals (Sweden)

    Full Text Available In order to motivate their group members to perform certain tasks, leaders use different leadership styles. These styles are based on leaders' backgrounds, knowledge, values, experiences, and expectations. The one-dimensional styles, used by many world leaders, are autocratic and democratic styles. These styles lie on the two opposite sides of the leadership spectrum. In order to precisely define the leadership styles on the spectrum between the autocratic leadership style and the democratic leadership style, leadership theory researchers use two dimensional matrices. The two-dimensional matrices define leadership styles on the basis of different parameters. By using these parameters, one can identify two-dimensional styles.

    2015-01-01

    Recent observations of dynamic water systems beneath the Greenland and Antarctic ice sheets have sparked renewed interest in modelling subglacial drainage. The foundations of today's models were laid decades ago, inspired by measurements from mountain glaciers, discovery of the modern ice streams and the study of landscapes evacuated by former ice sheets. Models have progressed from strict adherence to the principles of groundwater flow, to the incorporation of flow ‘elements’ specific to the subglacial environment, to sophisticated two-dimensional representations of interacting distributed and channelized drainage. Although presently in a state of rapid development, subglacial drainage models, when coupled to models of ice flow, are now able to reproduce many of the canonical phenomena that characterize this coupled system. Model calibration remains generally out of reach, whereas widespread application of these models to large problems and real geometries awaits the next level of development. PMID:27547082

    Background Downhill skiing is part of active life style in many residents of Alpine regions. However, only very little information is available whether downhill skiing on a regular basis is associated with a healthier life style resulting in the reduction of major risk factors for cardiovascular diseases and memory deficits when compared to the general population. Thus, the aim of the study was to compare life-style characteristics and cardiovascular risk factors between regular downhill skiers and the general population. Methods Self-reported health and life-style data were collected by questionnaire from 1259 long-term downhill skiers (971 males, aged 57.3 ± 14.6 years; 288 females, aged 47.7 ± 16.4 years) and compared with data from the general population. Results Long-term skiers showed more favourable life-style characteristics and a better health status than the general population. Prevalences of hypercholesterolemia, systemic hypertension, diabetes, the frequency of mental stress and the occurrence of memory deficits declined with increasing yearly skiing frequency. Conclusion Long-term alpine skiing on a regular basis may contribute to healthy aging by its association with a healthier life style. PMID:23987102

    We investigate the internal structure of the current sheet in the pulsar wind within force-free and two-fluid MHD approximations. Within the force-free approximation we obtain general asymptotic solution of the Grad-Shafranov equation for quasi-spherical pulsar wind up to the second order in small parameter ɛ = (Ωr/c)-1. The solution allows an arbitrary latitudinal structure of the radial magnetic field, including that obtained in the numerical simulations of oblique rotators. It is also shown that the shape of the current sheet does not depend on the latitudinal structure. For the internal region of the current sheet outside the fast magnetosonic surface where the force-free approximation is not valid we use two-fluid MHD approximation. Carrying out calculations in the comoving reference frame, we succeed in determining intrinsic electric and magnetic fields of a sheet. It allows us to analyse time-dependent effects which were not investigated up to now. In particular, we estimate the efficiency of the particle acceleration inside the sheet. Finally, after investigating the motion of individual particles in the time-dependent current sheet, we find the width of the sheet and its time evolution self-consistent.

    Few empirical studies have been undertaken on the communication styles of specific health-related disciplines. The objective of this study is to identify the communication styles of undergraduate health students at an Australian university. A cross-sectional study using a paper-based version of the Communicator Style Measure (CSM) was administered to a cohort of students enrolled in eight different undergraduate health-related courses. There were 1459 health students eligible for inclusion in the study. 860 students (response rate of 59%) participated in the study. Participants overall preferred the Friendly and Attentive communicator styles and gave least preference to the Contentious and Dominant styles. There was considerable similarity between participants from each of the health-related courses. There was no statistical difference in relation to communicator styles between the age of the participant or the year level they were enrolled in. These results show a preference for communicator styles which are facilitative of a client-centred approach, empathetic, and positive with interpersonal relationships. The lack of significant difference in communicator styles by year level further suggests that people disposed to such communicator styles are drawn to these health-related courses, rather than the specific field of study affecting their style.

    Childhood is a critical period in the development of obesity. Eating patterns established early in life track into later life. Therefore, parental approaches to feeding in their general parenting style, feeding styles, and specific feeding practices will have a profound impact on how children eat and grow. A systematic research review following PRISMA guidelines was conducted to identify, discuss and integrate recent research investigating the relationship between parenting styles, feeding styles, feeding practices, and body mass index (BMI) in children. Medline (Ovid), PsycINFO, Web of Science, and Food Science and Technology Abstracts were systematically searched using sensitive search strategies. Studies were limited to papers published in English between 2010 and February 2015 with participants aged 4–12 years old with outcomes including obesity, change in weight, or BMI. The search yielded 31 relevant quantitative peer-reviewed papers meeting all inclusion criteria: seven longitudinal, 23 cross-sectional, one randomized control trial. Associations between parenting style and child BMI were strongest and most consistent within the longitudinal studies. Uninvolved, indulgent or highly protective parenting was associated with higher child BMI, whereas authoritative parenting was associated with a healthy BMI. Similarly for feeding styles, indulgent feeding was consistently associated with risk of obesity within cross-sectional studies. Specific feeding practices such as restriction and pressure to eat were linked to BMI, especially within cross-sectional studies. Where child traits were measured, the feeding practice appeared to be responsive to the child, therefore restriction was applied to children with a high BMI and pressure to eat applied to children with a lower BMI. Behaviors and styles that are specific to the feeding context are consistently associated with child BMI. However, since obesity emerges over time, it is through longitudinal, carefully

    The objective of this investigation was to examine the stress and coping styles in Japanese nursing students. The principal measures of the stress and coping styles were the General Health Questionnaire (GHQ)-12 and Brief Coping Orientations to Problems Experienced scale. In a cross-sectional analysis, 1324 students completed the anonymous self-administered questionnaires including the scales earlier. Feeling stress, living with family, not eating breakfast every day, having no regular exercise and poor sleep were associated with GHQ responder (psychological distressed group). The most commonly reported source of stress was taking examinations, followed by relationships with friends, engaging in clinical practice and presenting reports. The three most common coping styles adopted by the nursing students were acceptance, self-distraction and using instrumental support. By logistic regression analysis of coping styles with GHQ responder, self-blame, active coping, acceptance and behavioural disengagement were highly associated with GHQ responder. The nursing school educators as well as students should be aware of stress management strategies (e.g. using active coping and avoiding self-blame) that may help prevent depression. © 2012 Wiley Publishing Asia Pty Ltd.

    Megreya, Ahmed M

    2013-02-01

    The Psychological Inventory of Criminal Thinking Styles (PICTS) has been applied extensively to the study of criminal behaviour and cognition. Increasingly growing evidence indicates that criminal thinking styles vary considerably among individuals, and these individual variations appear to be crucial for a full understanding of criminal behaviour. This study aimed to examine individual differences in criminal thinking as a function of emotional intelligence. A group of 56 Egyptian male prisoners completed the PICTS and Bar-On Emotional Quotient Inventory (EQ-i). The correlations between these assessments were examined using a series of Pearson correlations coefficients, with Bonferroni correction. General criminal thinking, reactive criminal thinking and five criminal thinking styles (mollification, cutoff, power orientation, cognitive indolence and discontinuity) negatively correlated with emotional intelligence. On the other hand, proactive criminal thinking and three criminal thinking styles (entitlement, superoptimism and sentimentality) did not associate with emotional intelligence. Emotional intelligence is an important correlate of individual differences in criminal thinking, especially its reactive aspects. Practical implications of this suggestion were discussed.

  4. ONE-DIMENSIONAL AND TWO-DIMENSIONAL LEADERSHIP STYLES

    OpenAIRE

    2007-01-01

    In order to motivate their group members to perform certain tasks, leaders use different leadership styles. These styles are based on leaders' backgrounds, knowledge, values, experiences, and expectations. The one-dimensional styles, used by many world leaders, are autocratic and democratic styles. These styles lie on the two opposite sides of the leadership spectrum. In order to precisely define the leadership styles on the spectrum between the autocratic leadership style and the democratic ...

    Understanding the origins of negative cognitive style could provide a means to prevent adult depression. Cognitive style is an important target for intervention because although it is not possible to remove the stress and adversities in people's lives, it may be possible to modify interpretation of such adversities through cognitive style. Children may develop a negative cognitive style through modeling the style of their mothers. However, findings have been inconsistent on the association. The authors tested the hypothesis that there is an independent association between maternal and offspring depressogenic cognitive style. Data from over 4,000 mothers and children from the Avon Longitudinal Study of Parents and Children cohort study in the United Kingdom were used to investigate the association between maternal depressogenic cognitive style before the offspring's birth and the offspring's depressogenic cognitive style at age 18. A positive association was observed between maternal and offspring cognitive styles: a one-standard-deviation increase in maternal depressogenic cognitive style score during pregnancy was significantly associated with a mean increase of 0.1 standard deviations in offspring depressogenic cognitive style score at age 18. This effect remained after adjusting for maternal and offspring depression and explained 21% of the association between maternal and offspring depression. Although the mechanisms remain to be elucidated, the findings are consistent with the idea that a mother's cognitive style (irrespective of her depression status) influences that of her child. This suggests that interventions to improve a mother's cognitive style could help prevent her offspring from developing depression during adulthood.

    Along the terrestrial margin of the southern North Sea, previous studies of the MIS 2 glaciation impacting eastern Britain have played a significant role in the development of principles relating to ice sheet dynamics (e.g. deformable beds), and the practice of reconstructing the style, timing, and spatial configuration of palaeo-ice sheets. These detailed terrestrially-based findings have however relied on observations made from only the outer edges of the former ice mass, as the North Sea Lobe (NSL) of the British-Irish Ice Sheet (BIIS) occupied an area that is now almost entirely submarine (c.21-15 ka). Compounded by the fact that marine-acquired data have been primarily of insufficient quality and density, the configuration and behaviour of the last BIIS in the southern North Sea remains surprisingly poorly constrained. This paper presents analysis of a new, integrated set of extensive seabed geomorphological and seismo-stratigraphic observations that both advances the principles developed previously onshore (e.g. multiple advance and retreat cycles), and provides a more detailed and accurate reconstruction of the BIIS at its southern-most extent in the North Sea. A new bathymetry compilation of the region reveals a series of broad sedimentary wedges and associated moraines that represent several terminal positions of the NSL. These former still-stand ice margins (1-4) are also found to relate to newly-identified architectural patterns (shallow stacked sedimentary wedges) in the region's seismic stratigraphy (previously mapped singularly as the Bolders Bank Formation). With ground-truthing constraint provided by sediment cores, these wedges are interpreted as sub-marginal till wedges, formed by complex subglacial accretionary processes that resulted in till thickening towards the former ice-sheet margins. The newly sub-divided shallow seismic stratigraphy (at least five units) also provides an indication of the relative event chronology of the NSL. While there

  7. A New System for Understanding Mid-crustal Sheeted Complexes in a Tilted Crustal Section, Joshua Tree National Park, California

    The western portion of Joshua Tree National Park exposes a tilted crustal section through continental arc crust from 0-30 km. A significant portion of the middle crust is represented by Mesozoic, tabular, intrusive, igneous bodies ranging from 0.1 to 100 m in thickness. While these igneous bodies range in composition (gabbro to peraluminous granites), texture (equigranular to porphyritic), and grain size (very fine to coarse), patterns emerge between different regions of "sheeted complexes" that may be related to their emplacement and geochemical history. No consistent method of describing and comparing sheeted complexes exists in the literature, so we have developed a method of classifying sheeted complexes at Joshua Tree NP, which may be broadly applicable to all sheeted bodies. We classify these sheeted complexes using the terms homogeneous/heterogeneous and focused/defocused. A homogeneous sheeted complex generally contains magmas within a 10 wt% SiO2 range, although we are still testing the validity of this number. A focused sheeted complex has adjacent sheets or close spacing between sheets and Jurassic to Cretaceous sheeted complexes in western Joshua Tree NP. At Keys View, we observe a heterogeneous, spatially focused sheeted complex with 0.1-2 m thick sheets recording pressures indicating 15-22 km depth from top to bottom. Compositions range from gabbro to peraluminous granite, although tonalites-granodiorites and two-mica garnet granites are volumetrically dominant. A zone of elongate plutons (in map view) lying structurally above this could potentially be considered as a very thickly sheeted, homogeneous, focused sheeted complex and is composed of granodiorites, granites, and two-mica garnet granites. A more thickly sheeted (2-10 m), homogeneous, focused, sheeted granite complex with pressures indicating a depth of approximately 12 km is found along the northern edge of the park. The number of sheets decreases and the average thickness increases as this

    Learning styles determine how people manage new information. Evidence-based medicine (EBM) involves the management of information in clinical practice. As a consequence, the way in which a person uses EBM can be related to his or her learning style. In order to tailor EBM education to the individual learner, this study aims to determine whether there is a relationship between an individual's learning style and EBM competence (knowledge/skills, attitude, behaviour). In 2008, we conducted a survey among 140 novice GP trainees in order to assess their EBM competence and learning styles (Accommodator, Diverger, Assimilator, Converger, or mixed learning style). The trainees' EBM knowledge/skills (scale 0-15; mean 6.8; 95%CI 6.4-7.2) were adequate and their attitudes towards EBM (scale 0-100; mean 63; 95%CI 61.3-64.3) were positive. We found no relationship between their knowledge/skills or attitudes and their learning styles (p = 0.21; p = 0.19). Of the trainees, 40% used guidelines to answer clinical questions and 55% agreed that the use of guidelines is the most appropriate way of applying EBM in general practice. Trainees preferred using evidence from summaries to using evidence from single studies. There were no differences in medical decision-making or in EBM use (p = 0.59) for the various learning styles. However, we did find a link between having an Accommodating or Converging learning style and making greater use of intuition. Moreover, trainees with different learning styles expressed different ideas about the optimal use of EBM in primary care. We found that EBM knowledge/skills and EBM attitudes did not differ with respect to the learning styles of GP trainees. However, we did find differences relating to the use of intuition and the trainees' ideas regarding the use of evidence in decision-making.

  10. Flexible Structural-Health-Monitoring Sheets

    Qing, Xinlin; Kuo, Fuo

    2008-01-01

    A generic design for a type of flexible structural-health-monitoring sheet with multiple sensor/actuator types and a method of manufacturing such sheets has been developed. A sheet of this type contains an array of sensing and/or actuation elements, associated wires, and any other associated circuit elements incorporated into various flexible layers on a thin, flexible substrate. The sheet can be affixed to a structure so that the array of sensing and/or actuation elements can be used to analyze the structure in accordance with structural-health-monitoring techniques. Alternatively, the sheet can be designed to be incorporated into the body of the structure, especially if the structure is made of a composite material. Customarily, structural-health monitoring is accomplished by use of sensors and actuators arrayed at various locations on a structure. In contrast, a sheet of the present type can contain an entire sensor/actuator array, making it unnecessary to install each sensor and actuator individually on or in a structure. Sensors of different types such as piezoelectric and fiber-optic can be embedded in the sheet to form a hybrid sensor network. Similarly, the traces for electric communication can be deposited on one or two layers as required, and an entirely separate layer can be employed to shield the sensor elements and traces.

    The effect of climate warming on the size of ice sheet margins in polar regions is considered. Particular attention is given to the possibility of a rapid response to warming on the order of tens to hundreds of years. It is found that the early response of the polar regions to climate warming would be an increase in the area of summer melt on the ice sheets and ice shelves. For sufficiently large warming (5-10C) the delayed effects would include the breakup of the ice shelves by an increase in ice drainage rates, particularly from the ice sheets. On the basis of published data for periodic changes in the thickness and melting rates of the marine ice sheets and fjord glaciers in Greenland and Antarctica, it is shown that the rate of retreat (or advance) of an ice sheet is primarily determined by: bedrock topography; the basal conditions of the grounded ice sheet; and the ice shelf condition downstream of the grounding line. A program of satellite and ground measurements to monitor the state of ice sheet equilibrium is recommended.

    Recently, application of high strength steel sheets for automobiles has increased in order to meet a demand of light weighting of automobiles to reduce a carbon footprint while satisfying collision safety. The formability of steel sheets generally decreases with the increase in strength. Fracture and wrinkles tend to occur easily during forming. The springback phenomenon is also one of the issues which we should cope with, because it makes it difficult to obtain the desired shape after forming. Advanced high strength steel sheets with high formability have been developed in order to overcome these issues, and at the same time application technologies have been developed for their effective utilization. These sheets are normally used for cold forming. As a different type of forming, hot forming technique has been developed in order to produce parts with ultra high strength. In this report, technologies developed at NSSMC in this field will be introduced.

  16. Robot-based additive manufacturing for flexible die-modelling in incremental sheet forming

    Rieger, Michael; Störkle, Denis Daniel; Thyssen, Lars; Kuhlenkötter, Bernd

    2017-10-01

    The paper describes the application concept of additive manufactured dies to support the robot-based incremental sheet metal forming process (`Roboforming') for the production of sheet metal components in small batch sizes. Compared to the dieless kinematic-based generation of a shape by means of two cooperating industrial robots, the supporting robot models a die on the back of the metal sheet by using the robot-based fused layer manufacturing process (FLM). This tool chain is software-defined and preserves the high geometrical form flexibility of Roboforming while flexibly generating support structures adapted to the final part's geometry. Test series serve to confirm the feasibility of the concept by investigating the process challenges of the adhesion to the sheet surface and the general stability as well as the influence on the geometric accuracy compared to the well-known forming strategies.

    Full Text Available By using the data of two spacecraft, TC-1 and ACE (Advanced Composition Explorer, a statistical study on the correlations between plasma sheet and solar wind has been carried out. The results obtained show that the plasma sheet at geocentric distances of about 9~13.4 Re has an apparent driving relationship with the solar wind. It is found that (1 there is a positive correlation between the duskward component of the interplanetary magnetic field (IMF and the duskward component of the geomagnetic field in the plasma sheet, with a proportionality constant of about 1.09. It indicates that the duskward component of the IMF can effectively penetrate into the near-Earth plasma sheet, and can be amplified by sunward convection in the corresponding region at geocentric distances of about 9~13.4 Re; (2 the increase in the density or the dynamic pressure of the solar wind will generally lead to the increase in the density of the plasma sheet; (3 the ion thermal pressure in the near-Earth plasma sheet is significantly controlled by the dynamic pressure of solar wind; (4 under the northward IMF condition, the ion temperature and ion thermal pressure in the plasma sheet decrease as the solar wind speed increases. This feature indicates that plasmas in the near-Earth plasma sheet can come from the magnetosheath through the LLBL. Northward IMF is one important condition for the transport of the cold plasmas of the magnetosheath into the plasma sheet through the LLBL, and fast solar wind will enhance such a transport process.

    Kolb portrays four learning styles depending on how an individual grasps or transforms experience: accommodating, assimilating, diverging, and converging. Past studies in surgery, medicine, and anesthesia identified the predominant learning style in each of these specialties. The prevalence of different learning styles and existence of a predominant style, if any, has not been reported for otolaryngology residency programs. The purpose of our study was to determine if otolaryngology residents have a preferred learning style that is different from the predominant learning styles reported for other specialties. We conducted a survey of the otolaryngology-head and neck surgery residents at two residency programs. Kolb's Learning Style Index (LSI) version 3.1 was administered to 46 residents from Johns Hopkins University and Kansas University Otolaryngology-Head and Neck Surgery programs. LSI is a widely used 12-item questionnaire, with each item followed by four options. The subjects graded the options depending on how the options applied to them. Forty-three otolaryngology residents completed the survey, with a response rate of 93.47%. The predominant learning style was converging (55.81%) followed by accommodating (18.61%), accounting for the learning styles of 74.42% of the total population. There were only 13.95% assimilating and 6.98% diverging learning styles. Two residents (4.65%) had their preference balanced across four learning styles. The predominant learning styles in otolaryngology were converging and accommodating, accounting for three fourths of the population. It would be desirable to modify our curriculum in a way that will optimize and facilitate learning.

    Full Text Available Introduction: The lack of mental health interferes with one's individual achievement and ability for undertaking the responsibilities of everyday life. Researches show that psychological well-being and parenting styles have an important role in ones' increasing general health. The current study examined the relationship between psychological well-being and parenting styles with students' mental health. Methods: This study was carried out on 278 students (124 boys and 154 girls of Boukan's high schools. The participants were asked to complete psychological well-being inventory and mental health parenting style questionnaire. Data was analyzed using of Pearson correlation coefficient and regression analysis. Results: The results showed that psychological well-being and authoritative parenting styles were significantly related with mental health; also, Permissive parenting styles has significant positive relationship with mental health. The regression analysis indicated that mental health is predictable by psychological well-being and parenting styles. Conclusion: The knowledge of parenting styles and psychological well-being and their relationships with general well-being can provide the significant implications on the provision of students' health. Parenting styles and psychological well-being, as significant variables in general well-being, needs more clinical research.

    The purpose of the study was to determine prevalent conflict management styles chosen by students in nursing and to contrast these styles with those chosen by students in allied health professions. The associations among the level of professional health care education and the style chosen were also determined. A convenience sample of 126 students in a comprehensive university completed the Thomas-Kilmann Conflict Mode Instrument (TKI), which requires respondents to choose behaviors most characteristic of their response to conflict and classifies these behaviors as one of five styles. There was no significant difference between the prevalent conflict management styles chosen by graduate and undergraduate nursing students and those in allied health. Some of the students were already licensed in their discipline; others had not yet taken a licensing exam. Licensure and educational level were not associated with choice of styles. Women and men had similar preferences. The prevalent style for nursing students was compromise, followed by avoidance. In contrast, avoidance, followed by compromise and accommodation, was the prevalent style for allied health students. When compared to the TKI norms, slightly more than one half of all participants chose two or more conflict management styles, commonly avoidance and accommodation at the 75th percentile or above. Only 9.8% of the participants chose collaboration at that level. Implications for nurse educators, researchers, and administrators are discussed.

    This study aimed to examine associations between symptoms of eating disorders and parenting style, in a non-clinical sample. One hundred and five mothers completed self-report measures of eating disorder symptoms and parenting style. Higher levels of eating disorder symptoms were associated with more authoritarian and permissive parenting styles. Authoritative parenting was not significantly related to eating disorder symptoms. The findings demonstrate that eating disorder symptoms in non-clinical individuals are related to less adaptive parenting styles. These findings have potential implications for clinicians working with mothers with eating disorders. 2009 Elsevier Ltd. All rights reserved.

  15. HOW DO ARCHITECTS THINK? LEARNING STYLES AND ARCHITECTURAL EDUCATION

    2010-07-01

    Full Text Available Architecture is a complex process involving the divergent resolution of a multitude of factors- social, ecological, technical, economic, functional, ethical and aesthetic. Despite this diversity all architectural problem solving processes share one common factor- they must be resolved spatially. This paper sets out to explore how best to develop these spatial thinking skills in young architects through addressing their learning styles in education. The primary hypothesis tested is twofold. First using the Solomon & Felder (2007 definition of learning styles and their Index of Learning Styles Questionnaire the average profile of a study group from the freshmen and sophomore architectural student body at the Architectural Engineering Program of the American University in Cairo is mapped and compared to that of a control group from the general population of the university from a cross-section of majors. Secondly, using the Spatial Ability test by Newton & Bristoll (2009, the spatial ability of both the control and study groups are measured and compared. The analysis of these results tests the assumption that the majority of architectural students will be visual, rather than verbal; and active, rather than reflective, learners; as well as exhibiting higher spatial abilities, as compared to the control group. The performance of students in these tests are then correlated against their learning styles profile using the following sets- low spatial ability against both reflective and verbal learning; moderate spatial ability against neutral learning styles; and high spatial ability against both active and visual learning. The results show a particular corroboration between high spatial ability and active learning in the entire group of students- both study, and control- as well as a strong corroboration between high spatial ability and visual learning- with a higher correlation in architecture students, reaching 100% in some classes. It is hoped that by

    Controlled manipulation of neutron spin is a critical tool for many neutron scattering techniques. We have constructed current-sheet, neutron spin flippers for use in Spin Echo Scattering Angle Measurement (SESAME) that comprise pairs of open-faced solenoids which introduce an abrupt field reversal at a shared boundary. The magnetic fields generated by the coils have been mapped and compared with both an analytical approximation and a numerical boundary integral calculation. The agreement is generally good, allowing the former method to be used for rapid calculations of the Larmor phase acquired by a neutron passing through the flipper. The evolution of the neutron spin through the current sheets inside the flipper is calculated for various geometries of the current-carrying conductors, including different wire shapes, arrangements, and common imperfections. The flipping efficiency is found to be sensitive to gaps between wires and between current sheets. SESAME requires flippers with high fields and flipping planes inclined to the neutron beam. To avoid substantial neutron depolarization, such flippers require an interdigitated arrangement of wires.

  17. Sheet flow caves of Kilauea Caldera, Hawaii County, Hawaii

    Directory of Open Access Journals (Sweden)

    William R. Halliday

    1998-01-01

    Full Text Available Terminal lobes of sheet flows of pahoehoe lava sometimes form three-dimensional nests, initially separated by partitions consisting of accreted ‘skins” of each lobe. Melting breaks down these partitions, forming a uniform flow unit. In Kilauea Caldera we have found and mapped sizable drained cavities in low-slope sheet flows. Their general pattern includes three-dimensional nests, with partially melted septa evident in some examples. Christmas Cave is the most extensive found to date, with 632 meters surveyed on two levels. It is located at the lower end of an inflated sheet flow tongue which underwent local deflation as a result of drainage through the cave after its parameters were partially fixed. Small conduit remnants persist in its boundary ridges. The major part of the cave consists of wide, low nestled chambers. Meltdown of such partitions is one of the few emplacement mechanisms of thermal erosion which may not involve any mechanical element. Additional caves in this caldera are being identified and studied.

  18. Results of the Marine Ice Sheet Model Intercomparison Project, MISMIP

    2012-05-01

    Full Text Available Predictions of marine ice-sheet behaviour require models that are able to robustly simulate grounding line migration. We present results of an intercomparison exercise for marine ice-sheet models. Verification is effected by comparison with approximate analytical solutions for flux across the grounding line using simplified geometrical configurations (no lateral variations, no effects of lateral buttressing. Unique steady state grounding line positions exist for ice sheets on a downward sloping bed, while hysteresis occurs across an overdeepened bed, and stable steady state grounding line positions only occur on the downward-sloping sections. Models based on the shallow ice approximation, which does not resolve extensional stresses, do not reproduce the approximate analytical results unless appropriate parameterizations for ice flux are imposed at the grounding line. For extensional-stress resolving "shelfy stream" models, differences between model results were mainly due to the choice of spatial discretization. Moving grid methods were found to be the most accurate at capturing grounding line evolution, since they track the grounding line explicitly. Adaptive mesh refinement can further improve accuracy, including fixed grid models that generally perform poorly at coarse resolution. Fixed grid models, with nested grid representations of the grounding line, are able to generate accurate steady state positions, but can be inaccurate over transients. Only one full-Stokes model was included in the intercomparison, and consequently the accuracy of shelfy stream models as approximations of full-Stokes models remains to be determined in detail, especially during transients.

    2015-04-27

    Patterning deformation within the plane of thin elastic sheets represents a powerful tool for the definition of complex and stimuli-responsive 3D buckled shapes. Previous experimental methods, however, have focused on sheets that access a limited number of shapes pre-programmed into the sheet, restricting the degree of dynamic control. Here, we demonstrate on-demand reconfigurable buckling of poly(N-isopropylacrylamide-co-acrylic acid) (PNIPAM) hydrogel network films containing gold nanoparticles (AuNPs) by patterned photothermal deswelling. Predictable, easily controllable, and reversible transformations from a single flat gel sheet to numerous different three-dimensional forms are shown. Importantly, the response time is limited by poroelastic mass transport, rather than photochemical switching kinetics, enabling reconfiguration of shape on timescales of several seconds, with further increases in speed possible by reducing film thickness. © 2015 WILEY-VCH Verlag GmbH & Co.

    2015-01-01

    Full Text Available Laser bending process of preloaded sheet metal was reviewed on theoretical researches, forming experiments, numerical simulations and material performance studies of formed sheets. Considering the pre-bending platforms that used in the forming experiments can only work on few simple pre-bending types and small sized sheet metals, a large and flexible pre-bending platform was developed by authors. Experiments were done on this platform. The results of experiments showed that different pre-bending types lead to bending sheet metals into different curved shapes and large sized structure components of flight vehicles can be formed using this process. Based on the current research status, further developments and challenges of this process are discussed.

    During navigation people may adopt three different spatial styles (i.e., Landmark, Route, and Survey). Landmark style (LS) people are able to recall familiar landmarks but cannot combine them with directional information; Route style (RS) people connect landmarks to each other using egocentric information about direction; Survey style (SS) people use a map-like representation of the environment. SS individuals generally navigate better than LS and RS people. Fifty-one college students (20 LS; 17 RS, and 14 SS) took part in the experiment. The spatial cognitive style (SCS) was assessed by means of the SCS test; participants then had to learn a schematic map of a city, and after 5 min had to recall the path depicted on it. During the learning and delayed recall phases, eye-movements were recorded. Our intent was to investigate whether there is a peculiar way to explore an environmental map related to the individual's spatial style. Results support the presence of differences in the strategy used by the three spatial styles for learning the path and its delayed recall. Specifically, LS individuals produced a greater number of fixations of short duration, while the opposite eye movement pattern characterized SS individuals. Moreover, SS individuals showed a more spread and comprehensive explorative pattern of the map, while LS individuals focused their exploration on the path and related targets. RS individuals showed a pattern of exploration at a level of proficiency between LS and SS individuals. We discuss the clinical and anatomical implications of our data.

  18. Attributional style and depression in multiple sclerosis: the learned helplessness model.

    Science.gov (United States)

    Vargas, Gray A; Arnett, Peter A

    2013-01-01

    Several etiologic theories have been proposed to explain depression in the general population. Studying these models and modifying them for use in the multiple sclerosis (MS) population may allow us to better understand depression in MS. According to the reformulated learned helplessness (LH) theory, individuals who attribute negative events to internal, stable, and global causes are more vulnerable to depression. This study differentiated attributional style that was or was not related to MS in 52 patients with MS to test the LH theory in this population and to determine possible differences between illness-related and non-illness-related attributions. Patients were administered measures of attributional style, daily stressors, disability, and depressive symptoms. Participants were more likely to list non-MS-related than MS-related causes of negative events on the Attributional Style Questionnaire (ASQ), and more-disabled participants listed significantly more MS-related causes than did less-disabled individuals. Non-MS-related attributional style correlated with stress and depressive symptoms, but MS-related attributional style did not correlate with disability or depressive symptoms. Stress mediated the effect of non-MS-related attributional style on depressive symptoms. These results suggest that, although attributional style appears to be an important construct in MS, it does not seem to be related directly to depressive symptoms; rather, it is related to more perceived stress, which in turn is related to increased depressive symptoms.

  19. Heliospheric current sheet inclinations at Venus and Earth

    Directory of Open Access Journals (Sweden)

    G. Ma

    Full Text Available We investigate the inclinations of heliospheric current sheet at two sites in interplanetary space, which are generated from the same solar source. From the data of solar wind magnetic fields observed at Venus (0.72 AU and Earth (1 AU during December 1978-May 1982 including the solar maximum of 1981, 54 pairs of candidate sector boundary crossings are picked out, of which 16 pairs are identified as sector boundaries. Of the remainder, 12 pairs are transient structures both at Venus and Earth, and 14 pairs are sector boundaries at one site and have transient structures at the other site. It implies that transient structures were often ejected from the coronal streamer belt around the solar maximum. For the 16 pairs of selected sector boundaries, we determine their normals by using minimum variance analysis. It is found that most of the normal azimuthal angles are distributed between the radial direction and the direction perpendicular to the spiral direction both at Venus and Earth. The normal elevations tend to be smaller than ~ 45° with respect to the solar equatorial plane, indicating high inclinations of the heliospheric current sheet, in particular at Earth. The larger scatter in the azimuth and elevation of normals at Venus than at Earth suggests stronger effects of the small-scale structures on the current sheet at 0.72 AU than at 1 AU. When the longitude difference between Venus and Earth is small (<40° longitudinally, similar or the same inclinations are generally observed, especially for the sector boundaries without small-scale structures. This implies that the heliospheric current sheet inclination tends to be maintained during propagation of the solar wind from 0.72 AU to 1 AU. Detailed case studies reveal that the dynamic nature of helmet streamers causes variations of the sector boundary structure.

    Light sheet fluorescence microscopy (LSFM) is gaining more and more popularity as a method to image embryonic development. The main advantages of LSFM compared to confocal systems are its low phototoxicity, gentle mounting strategies, fast acquisition with high signal to noise ratio and the possibility of imaging samples from various angles (views) for long periods of time. Imaging from multiple views unleashes the full potential of LSFM, but at the same time it can create terabyte-sized datasets. Processing such datasets is the biggest challenge of using LSFM. In this protocol we outline some solutions to this problem. Until recently, LSFM was mostly performed in laboratories that had the expertise to build and operate their own light sheet microscopes. However, in the last three years several commercial implementations of LSFM became available, which are multipurpose and easy to use for any developmental biologist. This article is primarily directed to those researchers, who are not LSFM technology developers, but want to employ LSFM as a tool to answer specific developmental biology questions. Here, we use imaging of zebrafish eye development as an example to introduce the reader to LSFM technology and we demonstrate applications of LSFM across multiple spatial and temporal scales. This article describes a complete experimental protocol starting with the mounting of zebrafish embryos for LSFM. We then outline the options for imaging using the commercially available light sheet microscope. Importantly, we also explain a pipeline for subsequent registration and fusion of multiview datasets using an open source solution implemented as a Fiji plugin. While this protocol focuses on imaging the developing zebrafish eye and processing data from a particular imaging setup, most of the insights and troubleshooting suggestions presented here are of general use and the protocol can be adapted to a variety of light sheet microscopy experiments.

  1. Adolescence and abstinence. Fact sheet.

    Science.gov (United States)

    1997-01-01

    This fact sheet presents statistics on adolescent sexual activity in the US and a brief description of comprehensive sex education and abstinence-only programs. The statistical profile indicates that over 50% of teenagers are virgins until at least 17 years of age. 20% of boys and 24% of girls are virgins by the age of 20 years. Only 6.9% of men 18-59 years old and 21% of women 18-59 years old were still virgins on their wedding night. However, among a sample of high school students, over 33% of male and female virgins had engaged in some form of heterosexual genital sexual activity in the preceding year. 29% of virgins had masturbated a partner of the opposite gender. 31% had been masturbated by a partner of the opposite gender. 9% had engaged in fellatio with ejaculation with a partner of the opposite gender. 10% had engaged in cunnilingus with a partner of the opposite gender. 1% had engaged in anal intercourse with a partner of the opposite gender. Comprehensive sex education aims to help adolescents postpone sexual intercourse until they are ready for mature relationships by helping them develop interpersonal skills to resist premature sexual involvement. Messages include information about sexual abstinence, contraception, and safer sex. A 1993 study found that sexual abstinence messages were one of the most frequently covered topics in state curricula and guidelines. Other key topics were families, decision making, and sexually transmitted diseases including AIDS. The least covered topics were sexual identity, shared sexual behavior, sexual response, masturbation, and abortion. There were only six studies of abstinence-only programs, of which at least two showed no impact on sexual or contraceptive behavior. The National Institute of Health says that abstinence-only programs ignore the success of other programs and conflict with science.

    The purpose of this study was to identify changes in sheet shape during thermoforming and the effect of the model position in the molding machine on fabricated mouthguard thickness. Ethylene vinyl acetate mouthguard sheets (3.8 mm thick) were used that had cross-stripes (10 × 10 mm), and the anteroposterior and bilateral lengths were used for measurements. Two forming machines were used: a vacuum- and a pressure-forming machine, and two heating conditions were investigated that defined as the time when sagging of the softened sheet was 15 mm (H-15) and 20 mm (H-20) below the clamp, and the length of each cross-stripes was measured. The area of each lattice was calculated using Bretschneider's formula to compare changes in sheet shape for each condition. Next, mouthguards were molded by forming machine where the working model was positioned under two different conditions: with the model anterior centered in the forming unit and with the model centered. The sheet thickness after fabrication was determined for the incisal and the molar portion, and dimensional measurements were obtained using a measuring device. Differences in the thickness were analyzed by two-way analysis of variance (anova). In both molding machines, the change in the area under H-20 was greater than H-15. While the increase in area tended to expand from the center of the sheet in concentric circles, the difference between the central and surrounding areas was only approximately 5%. For both molding machines, differences in thickness after molding due to setting position of the model were not observed. The results showed that shape changes of the sheet during thermoforming tend to concentrically and almost uniformly expand from the center and that it is important to center the sheet and the model when positioning the model in the forming unit. © 2016 John Wiley & Sons A/S.

    Photoreceptor (PR) transplantation may be a treatment for blindness secondary to PR degeneration. We studied different technical aspects of PR-sheet preparation. Geographic variation in the thickness of the cat PR layer (from the outer segments to the outer plexiform layer) and inner retina (width of the remainder of the retina) was studied. PR sheets (cat and human) were prepared through gelatin embedding and subsequent vibratoming or excimer laser ablation. Cat PR sheets were evaluated after transplantation. The thickness of the cat PR layer and inner retina varied in different regions. The superior central retina, including the area centralis, was thickest (PR layer: 115-123 microm, entire retina: 225-230 microm, in fixed tissue). The peripheral retina was approximately 40% thinner than the center. Fresh retina was approximately 7.9% thicker than the fixed retina. Both vibratomy and excimer laser ablation removed the inner retina, leaving a PR-layer sheet with good morphology. To produce good quality PR sheets with vibratomy, use of different gelatin concentrations (2% to 35%) at various stages of sheet preparation was crucial. To produce PR sheets of uniform thickness with excimer laser ablation, control of fluid on the retinal surface was critical. Twenty-four hours after PR transplantation surgery, donor PR cells were well oriented and in close contact with host retinal pigment epithelial cells. Gelatin supporting the transplant dissolved as early as 100 min after surgery. We confirmed and expanded the work of previous investigators and showed that cat and human PR sheets can be manufactured using vibratomy or excimer laser ablation. This preparation provides a well oriented and organized PR cell layer after transplantation.

    Research and development activities at the Jet Propulsion Laboratory (JPL) currently support the creation of a framework to formally evaluate the observational needs within earth system science. One of the pilot projects of this effort aims to quantify uncertainties in global mean sea level rise projections, due to contributions from the continental ice sheets. Here, we take advantage of established uncertainty quantification tools embedded within the JPL-University of California at Irvine Ice Sheet System Model (ISSM). We conduct sensitivity and Monte-Carlo style sampling experiments on forward simulations of the Greenland and Antarctic ice sheets. By varying internal parameters and boundary conditions of the system over both extreme and credible worst-case ranges, we assess the impact of the different parameter ranges on century-scale sea level rise projections. The results inform efforts to a) isolate the processes and inputs that are most responsible for determining ice sheet contribution to sea level; b) redefine uncertainty brackets for century-scale projections; and c) provide a prioritized list of measurements, along with quantitative information on spatial and temporal resolution, required for reducing uncertainty in future sea level rise projections. Results indicate that ice sheet mass loss is dependent on the spatial resolution of key boundary conditions - such as bedrock topography and melt rates at the ice-ocean interface. This work is performed at and supported by the California Institute of Technology's Jet Propulsion Laboratory. Supercomputing time is also supported through a contract with the National Aeronautics and Space Administration's Cryosphere program.

  6. Antibubbles and fine cylindrical sheets of air

    KAUST Repository

    Beilharz, D.

    2015-08-14

    Drops impacting at low velocities onto a pool surface can stretch out thin hemispherical sheets of air between the drop and the pool. These air sheets can remain intact until they reach submicron thicknesses, at which point they rupture to form a myriad of microbubbles. By impacting a higher-viscosity drop onto a lower-viscosity pool, we have explored new geometries of such air films. In this way we are able to maintain stable air layers which can wrap around the entire drop to form repeatable antibubbles, i.e. spherical air layers bounded by inner and outer liquid masses. Furthermore, for the most viscous drops they enter the pool trailing a viscous thread reaching all the way to the pinch-off nozzle. The air sheet can also wrap around this thread and remain stable over an extended period of time to form a cylindrical air sheet. We study the parameter regime where these structures appear and their subsequent breakup. The stability of these thin cylindrical air sheets is inconsistent with inviscid stability theory, suggesting stabilization by lubrication forces within the submicron air layer. We use interferometry to measure the air-layer thickness versus depth along the cylindrical air sheet and around the drop. The air film is thickest above the equator of the drop, but thinner below the drop and up along the air cylinder. Based on microbubble volumes, the thickness of the cylindrical air layer becomes less than 100 nm before it ruptures.

    Full Text Available We study the effect of stylistic differences on the nature of pictorial spaces as they appear to an observer when looking into a picture. Four pictures chosen from diverse styles of depiction were studied by 2 different methods. Each method addresses pictorial depth but draws on a different bouquet of depth cues. We find that the depth structures are very similar for 8 observers, apart from an idiosyncratic depth scaling (up to a factor of 3. The differences between observers generalize over (very different pictures and (very different methods. They are apparently characteristic of the person. The differences between depths as sampled by the 2 methods depend upon the style of the picture. This is the case for all observers except one.
