    Paech, Juliane; Schindler, Ines; Fagundes, Christopher P

    Attachment avoidance and anxiety are associated with negative emotions. However, the mechanisms underlying these associations are not fully understood. We investigated environmental mastery and positive relations with others as two mechanisms behind the attachment-emotion link in a sample of 343 adults. As predicted, attachment avoidance and anxiety were related to greater fear, hostility, envy and depression through lower mastery. Contrary to our hypothesis, positive relations mediated only the attachment-depression link. In addition, by adopting a moderated mediation approach, we were able to show that mastery mattered most for individuals high on avoidance: The indirect effect of avoidance through lack of mastery on fear, hostility and depression (but not on envy) increased with higher avoidance scores. Contrary to our predictions, poor relationships did not matter more as sources of negative emotions as anxiety increased. These findings underscore that the emotional life of avoidantly attached individuals is especially jeopardised by poor mastery.

    Cao, Jennifer

    This research, in response to the lack of empirical evidence of the impact of culturally relevant pedagogy (CRP) on Latino students in science education, examined the effect CRP on Latino students' engagement and content mastery. Quantitative research was conducted with a treatment group that received an intervention unit on states of matter with CRP approaches and a comparison group that did not receive the intervention. The sample comprised approximately 189 eighth-grade students from a Southern Californian middle school. The research findings reveal that CRP approaches had a statistically significant positive effect on student engagement of all ethnic groups in this study, particularly Latino students, while CRP approaches had a statistically significant negative effect on Latino students' content mastery. Three recommendations result from this study, including professional development of CRP for educators, professional development of CRP for educational leaders, and using CRP to address multiculturalism.

    Bebanic, Vedrana; Clench-Aas, Jocelyne; Raanaas, Ruth Kjærsti; Bang Nes, Ragnhild

    2015-07-03

    The aims of this study were to examine associations between reported exposure to psychological and physical violence and psychological distress (PD) among men and women, and to explore the possible mediating or moderating roles of sense of mastery and social support. We used data from the nationally representative Norwegian Health and Level of Living Survey in 2005 and 2012 (Weighted N = 19,386). PD was measured with the Hopkins Symptom Checklist-25, using the subscales for anxiety and depression separately and in combination. Analyses were conducted using hierarchical logistic regression with complex sample adjustment. Altogether, 3.8% of men and 5.4% of women reported psychological violence during the last 12 months, while 2.3% and 1.6% reported physical violence, respectively. Both forms of violence were associated with excess risk of comorbid anxiety and depressive symptoms above clinical cut-point (CAD) in men and women alike, and CAD occurred more frequently than anxiety or depressive problems separately. Sense of mastery, but not social support, partly mediated the association between both forms of violence and CAD in men, whereas both partly mediated the association between psychological violence and CAD in women. No moderator role was indicated. Overall, the results provide evidence for excess risk of PD, particularly CAD, in men and women reporting exposure to violence. Sense of mastery and to a lesser degree social support were shown to constitute significant mediators, underscoring the importance of systems for strengthening coping strategies and social support among violence victims, such as psychological and practical support by the health services. © The Author(s) 2015.

    2014-07-01

    Assessing subjective age perception (SAP) and changes in SAP as well as exploring which variables of socio-demographic, health and personal mastery independently predicted SAP. The panel data are from two waves of the Norwegian Study on the Life Course, Ageing and Generations (NorLAG). Our sample consists of 2471 people aged 40-79 years at baseline who were surveyed in 2002/2003 (T1) and 2007/2008 (T2). Univariate and multiple regressions were performed; multivariate analyses assessing the relative importance of the independent variables (at T1) for the SAP at T2. Older chronological age, good physical health, good mental health, a high level of personal mastery and having lower education significantly predicted a youthful SAP. For the whole sample, older age and a high level of personal mastery were the most important predictors. For those aged 40-49 being a man, having lower education, good physical health and high personal mastery predicted a younger SAP, whereas in the group aged 50-59 years being married/cohabiting and having a high level of education were predictors of an older SAP. For those aged 60-69, high personal mastery was the only independent predictor of a younger SAP. For those aged 70-79 years, only health - good mental and physical health - independently predicted a younger SAP. Most respondents feel younger than their chronological age, the more the older they are. Self-rated physical and mental health and personal mastery are associated with SAP and vary in different age groups.

  12. Cortex Parcellation Associated Whole White Matter Parcellation in Individual Subjects

    2017-07-01

    Full Text Available The investigation of specific white matter areas is a growing field in neurological research and is typically achieved through the use of atlases. However, the definition of anatomically based regions remains challenging for the white matter and thus hinders region-specific analysis in individual subjects. In this article, we focus on creating a whole white matter parcellation method for individual subjects where these areas can be associated to cortex regions. This is done by combining cortex parcellation and fiber tracking data. By tracking fibers out of each cortex region and labeling the fibers according to their origin, we populate a candidate image. We then derive the white matter parcellation by classifying each white matter voxel according to the distribution of labels in the corresponding voxel from the candidate image. The parcellation of the white matter with the presented method is highly reliable and is not as dependent on registration as with white matter atlases. This method allows for the parcellation of the whole white matter into individual cortex region associated areas and, therefore, associates white matter alterations to cortex regions. In addition, we compare the results from the presented method to existing atlases. The areas generated by the presented method are not as sharply defined as the areas in most existing atlases; however, they are computed directly in the DWI space of the subject and, therefore, do not suffer from distortion caused by registration. The presented approach might be a promising tool for clinical and basic research to investigate modalities or system specific micro structural alterations of white matter areas in a quantitative manner.

    This study aimed to see a teachers mathematical communication profile in explaining a subject matter. It is a qualitative research. A high-school junior teacher (i.e., a teacher with 1- to 5-year experience) teaching mathematics at X-Social Class was selected as the subject of this study. The data was collected by observing the teachers mathematical communication in explaining a given material (i.e., the rule of sine) in class and an in-depth interview would be organized respectively. The result showed that the junior teacher explained the subject matter in systematic, complete, fluent, and centered manner. In this case, she began with reminding students on the previous material related to the current material to be learned, informing the current learning objectives, and finally delivering the subject matter. To support her explanation, the teacher also provided some related information, led the students attention into the given material by asking them particular related questions, and did not use any confusing terms. However, the study found that some of high-school teachers still used less appropriate language in explaining materials.

  19. Learning, knowledge building, and subject matter knowledge in school science

    Science.gov (United States)

    van Aalst, Jan Cornelis Wouterus

    Following a theoretical analysis of constructivist approaches to collaborative learning, a curriculum development model, the Learning to Knowledge Building Model, is proposed. Two empirical studies of student work with Computer Supported Intentional Learning Environment (CSILE) are then presented; these lend support to the model and explicate in detail the nature and extent of the knowledge developed by elementary school students. The first study is a content analysis of a database developed by a combined Grade 5/6 class as part of a unit on heat and matter, conducted after the children completed their work; the analysis assumes the point of view of a subject matter specialist in the field of the students' inquiry. The second study was conducted while the students' investigation was in progress, and takes the point of view of curriculum coverage; it involved a teacher who used a different model of database use, as well as different subject matter. The proposed LKB model is based on a distinction Bereiter and Scardamalia (1996a) have made between learning and knowledge building (i.e., progressive collaborative problem solving); its aim is to support the design and planning of curriculum units and classroom practices in which knowledge building is central. An important feature of the model is the attention given to ensuring that students learn to evaluate their knowledge and to ask the questions that can advance shared knowledge. Among the findings of the first study are: (a) students who wrote more notes that explicated their commonsense knowledge early in the unit, by means of mixed framework notes, tended to write more notes of high scientific merit later; (b) some of the students in this category tried out their ideas in diverse problem contexts; and (c) they tended to dominate the discussions they started. The second study provides additional insight into the role of the teacher, and the potential role of subject matter specialists, in knowledge building; it

    Coordinated patterns of cortical morphology have been described as structural graphs and previous research has demonstrated that properties of such graphs are altered in Alzheimer's disease (AD). However, it remains unknown how these alterations are related to cognitive deficits in individuals, as such graphs are restricted to group-level analysis. In the present study we investigated this question in single-subject grey matter networks. This new method extracts large-scale structural graphs where nodes represent small cortical regions that are connected by edges when they show statistical similarity. Using this method, unweighted and undirected networks were extracted from T1 weighted structural magnetic resonance imaging scans of 38 AD patients (19 female, average age 72±4 years) and 38 controls (19 females, average age 72±4 years). Group comparisons of standard graph properties were performed after correcting for grey matter volumetric measurements and were correlated to scores of general cognitive functioning. AD networks were characterised by a more random topology as indicated by a decreased small world coefficient (p = 3.53×10(-5)), decreased normalized clustering coefficient (p = 7.25×10(-6)) and decreased normalized path length (p = 1.91×10(-7)). Reduced normalized path length explained significantly (p = 0.004) more variance in measurements of general cognitive decline (32%) in comparison to volumetric measurements (9%). Altered path length of the parahippocampal gyrus, hippocampus, fusiform gyrus and precuneus showed the strongest relationship with cognitive decline. The present results suggest that single-subject grey matter graphs provide a concise quantification of cortical structure that has clinical value, which might be of particular importance for disease prognosis. These findings contribute to a better understanding of structural alterations and cognitive dysfunction in AD.

  1. Landscape History and Theory: from Subject Matter to Analytical Tool

    Directory of Open Access Journals (Sweden)

    Jan Birksted

    2003-10-01

    Full Text Available This essay explores how landscape history can engage methodologically with the adjacent disciplines of art history and visual/cultural studies. Central to the methodological problem is the mapping of the beholder - spatially, temporally and phenomenologically. In this mapping process, landscape history is transformed from subject matter to analytical tool. As a result, landscape history no longer simply imports and applies ideas from other disciplines but develops its own methodologies to engage and influence them. Landscape history, like art history, thereby takes on a creative cultural presence. Through that process, landscape architecture and garden design regains the cultural power now carried by the arts and museum studies, and has an effect on the innovative capabilities of contemporary landscape design.

Experiments, research, and experience see positive effects of adding sign language in communication methods to pre-school and K-12 education. Augmentative, alternative, interactive, accommodating, and enriching strategies using sign language aid learners in balancing the skills needed to mastery of one language or multiple languages. Theories of learning that embrace play, drama, motion, repetition, socializing, and self-efficacy connect to the options for using sign language with learners in inclusive and mainstream classes. The methodical use of sign language by this researcher-educator over two and a half decades showed signing does build thinking skills, add enjoyment, stimulate communication, expand comprehension, increase vocabulary acquisition, encourage collaboration, and helps build appreciation for cultural diversity.

    Full Text Available The aim of the research is to analyze the subject matter of a country’s competitiveness and to characterize statistical indexes of competitiveness known in the international practice from the perspective of a more elaborated theory of market competition. This aim follows from the identified problems. First, there are no generally accepted interpretation and joint understanding of competition and competitiveness at country level. Even the international organizations giving estimations of global competitiveness disagree on definitions of competitiveness. Secondly, there is no relation to the theory of market competition in the available source materials on competitiveness of the country without original methodology. Thirdly, well-known statistical indexes of global competitiveness do not have enough theoretical justification and differ in sets of factors. All this highlights the incompleteness of the methodology and methodological support of studying competitiveness at country level.Materials and methods. The research is based on the methodology of statistics, economic theory and marketing. The authors followed the basic principle of statistical methodology – requirement of continuous combination of qualitative and quantitative analysis, when the research begins and ends with qualitative analysis. A most important section of statistical methodology is widely used – construction of statistical indexes. In the course of the analysis, a method of statistical classifications is applied. A significant role in the present research is given to the method of generalizing and analogue method, realizing that related terms should mean similar and almost similar contents. Modeling of competition and competitiveness is widely used in the present research, which made it possible to develop a logical model of competition following from the competition theory.Results.

  8. Mastery-style exercises in physics

    Science.gov (United States)

    Schroeder, Noah D.

    Mastery learning employs repeated cycles of instructional support and formative assessment to help students achieve desired skills. Instructional objectives are broken into small pieces, and students master those pieces in successive order by performing to a set standard on an assessment for each objective. If a student cannot master an objective, instructional support is provided, and the student is reassessed. Mastery learning has been proved effective in many subject areas, but comparatively little research has been done on applying it in physics instruction. This dissertation details the path taken that culminated in the use of mastery-inspired exercises to teach students basic skills in introductory physics courses. The path that led to our choice of mastery began with an attempt to provide students with extra practice and formative assessment through weekly practice tests with corresponding solutions, with the goal of helping them better prepare for summative exams in an introductory physics course. No effect was seen, and participation was very low. Investigating how students learn from solutions revealed that they are poor evaluators of their understanding of provided solutions and struggle to retain the skills taught in those solutions. In a follow-up clinical experiment that provided students with solutions, required them to recall the solutions from memory, and re-presented the solutions for restudy, students showed strong retention as well as the ability to transfer information from the solutions to new situations. These results inspired the formal use of mastery learning as an instructional paradigm due to its requirement that students repeatedly recall information from solutions and apply it to new situations. Mastery-style exercises were first created and tested in clinical trials, followed by two in-course implementations. In the clinical trials, students completed a set of questions on a particular skill, and if they failed to master that skill

  12. GP teachers' subject matter knowledge in the context of a tutorial: the preparation and delivery compared.

    Cantillon, Peter; de Grave, Willem

    2012-05-01

    Clinical teachers use several different types of knowledge in the act of teaching. These include content knowledge (subject matter), knowledge of how to teach (pedagogy) and knowledge of learners (context). Most attention in faculty development has been on how to teach rather than what is taught. The quality of a teacher's subject matter knowledge is likely to be a critical determinant of how well a subject is presented, communicated and learned. We therefore set out to examine teachers' subject matter knowledge in the context of a general practice tutorial on grade 1 hypertension. This study is part of a larger study that employed a mixed method approach (concept mapping, phenomenological interviews and video-stimulated recall) to examine differences between clinical educators in subject matter knowledge, pedagogical knowledge and knowledge of the learning environment in the context of general practice education. This paper presents the concept map data findings from the larger study as well as the parts of the phenomenological interviews that relate to subject matter knowledge and beliefs. We found that there were marked differences in the quality and elaborative structure of GP teachers' knowledge in the concept maps completed prior to the tutorials. These differences were also predictive of differences in the content presented to learners in tutorials. Teachers' beliefs about subject matter were also likely to have affected what they chose to teach about and how they presented it. Subject matter knowledge varies considerably between GP teachers in the context of a common and relatively simple tutorial. Differences in the quality of subject matter knowledge matter because they have a profound effect on what is learned and how it is learned. Faculty development for clinical educators needs to pay heed to the quality of subject matter knowledge in addition to its more common pedagogical focus.

    The paper briefly explores the manifestation of ethical leadership and examines at length the dimension of character formation. It argues that personal mastery is indispensable to sound character formation because leaders with high personal mastery are more likely to exhibit a disciplined pattern of behavior that is guided by a deep personal vision and enduring moral principles. The paper then discusses some of the sources that the leader can tap to attain personal mastery that leads to the self-transformation of both the leader and of the followers.

The subject of my teaching is economic theory. We face economic questions every day and in all areas of life. Therefore, my purpose is to acquaint college students, who do not study economics, with economic basics, to develop economic thinking and literacy. Greatest attention is paid to describe economic concepts and to use them in practice. Economics can not be learned through observing, one must work, analyse, solve practical exercises, search for correct answers. The purpose of the article is to assess the students‘ approach to the relevance of the subjects of economics. It is sought to identify the possibilities of applying new methods for teaching economic subjects and of selecting a teaching method in accordance with the students‘ level of preparation. The assessment of the research carried out enables to conclude that teaching economics forms students‘ capacities of a wide range, stimulates their self-expression, prepares young people to work in market conditions. The following methods of the research have been employed: pedagogic observation, questionnaire (survey, analysis of scientific literature and generalization.

  20. Sovereignty without Mastery

    Directory of Open Access Journals (Sweden)

    Patrick McLane

    2012-12-01

    Full Text Available In The Beast and the Sovereign v.1, Derrida argues that classical sovereignty is linked to the performative act of declaring oneself master. Thus, each sovereign asserts a distinction between the masterful self and the mastered other. Derrida contends that the sovereign distinction between self and other maps onto a distinction between sovereign autonomy and a mechanical determination said to characterize others of all kinds. This gives rise to a differentiated binary between responsibility, capacity and restraint on the one side against reaction, instinct and danger on the other, which, Derrida suggests, operates across traditional separations, such as man/animal, man/machine, mind/body and, of course, sovereign and beast. This paper argues that Derrida’s reading of Paul Celan and Georges Bataille may be understood as a pursuit of an alternative sovereignty. This alternative sovereignty would be without mastery and its binaries. I suggest that Derrida finds such an alternative sovereignty in the “majesty” of poetry, which, in his own poetic gesture, allows him to upset traditional distinctions.

  1. Subjectivity and Objectivity: A Matter of Life and Death?

    2008-10-01

    Full Text Available In this paper, it is argued that the question ldquo;What is life?rdquo; time and again emergesmdash;and within the confines of an objectivistic/subjectivistic frame of thought has to emergemdash;as a symptom, a non-deciphered, cryptic message that insists on being interpreted. br /Our hypothesis is that the failure to measure up the living to the standards of objectification has been taken too frequently from an objectivistic angle, leading to a simple postponement of an objective treatment of the living, and meanwhile confining it to the domain of the subjective, the relative and the metaphorical. As a consequence, the truly important question of the co-constitutive relation between objectivity and subjectivity is thereby evaded. A critical, transcendental account can be relevant in this regard, not only because of the fact that objectivity and subjectivity are seen as co-constitutive, but also because it addresses the question of the embeddedness of objectivity and subjectivity from within the living dynamics.br /This hypothesis will be articulated on the basis of Erwin Schrouml;dingerrsquo;s famous little book on ldquo;What is life?rdquo;, in dialogue with Robert Rosenrsquo;s critical reading of it. It appears that Schrouml;dinger considered the living as a genuine challenge for classical objectification procedures. However, it is doubtful whether this brought him to a critical reading of objectivity or to the acknowledgment of a constitutive role of subjectivity in relation to objectivity. We argue that his viewpoint has the merit ofnbsp; expressing the difficulty of the living within the field of the physical sciences, but does not really transcend the objectivism/subjectivism opposition. At this point, Rosenrsquo;s relational account takes up the challenge more radically by acknowledging the need for a new epistemology and a new metaphysics in relation to living systems, and by attributing a place to classical objectivity from within this

  8. Fiberprint: A subject fingerprint based on sparse code pooling for white matter fiber analysis.

    Science.gov (United States)

    Kumar, Kuldeep; Desrosiers, Christian; Siddiqi, Kaleem; Colliot, Olivier; Toews, Matthew

    2017-09-01

    White matter characterization studies use the information provided by diffusion magnetic resonance imaging (dMRI) to draw cross-population inferences. However, the structure, function, and white matter geometry vary across individuals. Here, we propose a subject fingerprint, called Fiberprint, to quantify the individual uniqueness in white matter geometry using fiber trajectories. We learn a sparse coding representation for fiber trajectories by mapping them to a common space defined by a dictionary. A subject fingerprint is then generated by applying a pooling function for each bundle, thus providing a vector of bundle-wise features describing a particular subject's white matter geometry. These features encode unique properties of fiber trajectories, such as their density along prominent bundles. An analysis of data from 861 Human Connectome Project subjects reveals that a fingerprint based on approximately 3000 fiber trajectories can uniquely identify exemplars from the same individual. We also use fingerprints for twin/sibling identification, our observations consistent with the twin data studies of white matter integrity. Our results demonstrate that the proposed Fiberprint can effectively capture the variability in white matter fiber geometry across individuals, using a compact feature vector (dimension of 50), making this framework particularly attractive for handling large datasets.

  13. Healthy Aging Among Older Black and White Men: What Is the Role of Mastery?

    Science.gov (United States)

    Latham-Mintus, Kenzie; Vowels, Ashley; Huskins, Kyle

    2017-07-21

    This research explores black-white differences in healthy aging and investigates whether mastery acts as a buffer against poor health for older black and white men. Using data from the Health and Retirement Study (HRS) (2008-2012), a series of binary logit models were created to assess healthy aging over a 2-year period. Healthy aging was defined as good subjective health and free of disability at both waves. Mastery was lagged, and analyses (n = 4,892) controlled for social and health factors. Black-white disparities in healthy aging were observed, where older black men had lower odds of healthy aging. Mastery was associated with higher odds of healthy aging, and race moderated the relationship between mastery and healthy aging. The predicted probability of healthy aging was relatively flat across all levels of mastery among black men, yet white men saw consistent gains in the probability of healthy aging with higher levels of mastery. In race-stratified models, mastery was not a significant predictor of healthy aging among black men. High levels of mastery are linked to positive health-often acting as a buffer against stressful life events. However, among older black men, higher levels of mastery did not necessarily equate to healthy aging.

    Dunn, William; Dong, Yue; Zendejas, Benjamin; Ruparel, Raaj; Farley, David

    2017-02-01

    Healthcare organizations, becoming increasingly complex, need to use simulation techniques as a tool to provide consistently safe care. Mastery learning techniques minimize variation in learner outcome, thus improving the consistency and cost-effectiveness of care. Today׳s organizations (and their teams of decision makers) exist within varying states of transformation. These transformational times afford opportunities to use mastery learning concepts at an organizational level and to affect necessary change(s). Evolving technologies, including simulation, have provided mechanisms to enhance system performance, reducing reliance on custom-built "problem-solving" solutions for individual system needs. As such, simulation has emerged as an increasingly necessary organizational tool in improving value-driven, consistent processes of care. Both computer-based and non-computer-based algorithms of healthcare simulations offer distinct advantages in improving system performance over traditional methods of quality improvement. Simulation as a process engineering tool, integrated with mastery learning techniques, provides powerful platforms for improving value-based care.

  5. John Dewey on theory of learning and inquiry: The scientific method and subject matter

    Science.gov (United States)

    Chen, Po-Nien

    This study examines the educational debate between Dewey and some of his critics on the merits of learning the scientific method. Four of Dewey's critics---Hutchins, Hirsch, Hirst, and Scheffler criticize Dewey for over-emphasizing the importance of the scientific method and under-emphasizing the importance of subject matter in education. This dissertation argues that these critics misunderstand Dewey's use of the scientific method and its importance in education. It argues that Dewey conceives of the scientific method in two different ways: first as an attitude and second as a tool. It also argues that, by failing to understand this critical distinction, these critics misunderstand the role of the scientific method in education. The dissertation concludes by showing that, educationally, Dewey's ideas of the scientific method have different meanings in different context. It analyzes the scientific method as empirical method, critical thinking, cooperative learning, and creative thinking, and shows the place of subject matter in each of them.

    2017-04-01

    This study aims to add clarity to the relationship between deep and periventricular brain white matter hyperintensities (WMHs), cerebral blood flow (CBF), and cerebrovascular risk in older persons. Deep white matter hyperintensity (dWMH) and periventricular white matter hyperintensity (pWMH) and regional gray matter (GM) and white matter (WM) blood flow from arterial spin labeling were quantified from magnetic resonance imaging scans of 26 cognitively normal elderly subjects stratified by cerebrovascular disease (CVD) risk. Fluid-attenuated inversion recovery images were acquired using a high-resolution 3-dimensional (3-D) sequence that reduced partial volume effects seen with slice-based techniques. dWMHs but not pWMHs were increased in patients at high risk of CVD; pWMHs but not dWMHs were associated with decreased regional cortical (GM) blood flow. We also found that blood flow in WM is decreased in regions of both pWMH and dWMH, with a greater degree of decrease in pWMH areas. WMHs are usefully divided into dWMH and pWMH regions because they demonstrate differential effects. 3-D regional WMH volume is a potentially valuable marker for CVD based on associations with cortical CBF and WM CBF.

  9. The charismatic journey of mastery learning.

    Science.gov (United States)

    Inui, Thomas S

    2015-11-01

    A collection of articles in this issue examine the concept of mastery learning, underscoring that our journey is from a 19th-century construct for assuring skill development (i.e., completing a schedule of rotations driven by the calendar) to a 21st-century sequence of learning opportunities focused on acquiring mastery of special key competencies within clerkships or other activities. Mastery learning processes and standards have the potential to clarify learning goals and competency measurement issues in medical education. Although mastery learning methods originally focused on developing learners' competency with skillful procedures, the author of this Commentary posits that mastery learning methods may be usefully applied more extensively to broader domains of skillful practice, especially those practices that can be linked to outcomes of care. The transition to mastery-focused criteria for educational advancement is laudatory, but challenges will be encountered in the journey to mastery education. The author examines several of these potential challenges, including expansion of mastery learning approaches to effective but relational clinician advice-giving and counseling behaviors, developing criteria for choosing critical competencies that can be linked to outcomes, avoiding a excessively fragmented approach to mastery measurement, and dealing with "educational comorbidity."

    Ravagli, Carlo; Pognan, Francois; Marc, Philippe

    2017-01-01

    The lack of controlled terminology and ontology usage leads to incomplete search results and poor interoperability between databases. One of the major underlying challenges of data integration is curating data to adhere to controlled terminologies and/or ontologies. Finding subject matter experts with the time and skills required to perform data curation is often problematic. In addition, existing tools are not designed for continuous data integration and collaborative curation. This results in time-consuming curation workflows that often become unsustainable. The primary objective of OntoBrowser is to provide an easy-to-use online collaborative solution for subject matter experts to map reported terms to preferred ontology (or code list) terms and facilitate ontology evolution. Additional features include web service access to data, visualization of ontologies in hierarchical/graph format and a peer review/approval workflow with alerting.

  11. Habitual sleep durations and subjective sleep quality predict white matter differences in the human brain

    Directory of Open Access Journals (Sweden)

    Sakh Khalsa

    2017-06-01

    Full Text Available Self-imposed short sleep durations are increasingly commonplace in society, and have considerable health and performance implications for individuals. Reduced sleep duration over multiple nights has similar behavioural effects to those observed following acute total sleep deprivation, suggesting that lack of sleep affects brain function cumulatively. A link between habitual sleep patterns and functional connectivity has previously been observed, and the effect of sleep duration on the brain's intrinsic functional architecture may provide a link between sleep status and cognition. However, it is currently not known whether differences in habitual sleep patterns across individuals are related to changes in the brain's white matter, which underlies structural connectivity. In the present study we use diffusion–weighted imaging and a group comparison application of tract based spatial statistics (TBSS to investigate changes to fractional anisotropy (FA and mean diffusivity (MD in relation to sleep duration and quality, hypothesising that white matter metrics would be positively associated with sleep duration and quality. Diffusion weighted imaging data was acquired from a final cohort of 33 (23–29 years, 10 female, mean 25.4 years participants. Sleep patterns were assessed for a 14 day period using wrist actigraphs and sleep diaries, and subjective sleep quality with the Pittsburgh Sleep Quality Index (PSQI. Median splits based on total sleep time and PSQI were used to create groups of shorter/longer and poorer/better sleepers, whose imaging data was compared using TBSS followed by post-hoc correlation analysis in regions identified as significantly different between the groups. There were significant positive correlations between sleep duration and FA in the left orbito-frontal region and the right superior corona radiata, and significant negative correlations between sleep duration and MD in right orbito-frontal white matter and the right

  13. Knot numbers used as labels for identifying subject matter of a khipu

    Directory of Open Access Journals (Sweden)

    2013-03-01

    Full Text Available This investigation presents a new way to look at the numerical khipu, a knotted-string recording device from Pachacamac (Peru, and the types of information it contains. In addition to celestial coordinates, khipu knots apparently pertain to an early form of double-entry accounting. This study hypothesizes that the khipu sample has the recording capacity needed to register double-entry-like accounts. After the identification of its subject matter, the khipu sample was studied in an attempt to ascertain whether the knot values could represent instructions from the Inca state administration to a local accounting center. The results indicate that the numerical information in the pairing quadrants (determined by the distribution of S- and Z-knots should be read from top to bottom along the full length of the string and can then provide certain complementary details regarding the projected corn stocks of the Inca stat

  14. Subject matter knowledge, classroom management, and instructional practices in middle school science classrooms

    Lee, Okhee

    This study examined the interrelationships among three major components of classroom teaching: subject matter content knowledge, classroom management, and instructional practices. The study involved two middle school science classes of different achievement levels taught by the same female teacher. The teacher held an undergraduate degree with a major in social studies and a minor in mathematics and science from an elementary teacher education program. The findings indicated that the teacher's limited knowledge of science content and her strict classroom order resulted in heavy dependence on the textbook and students' individual activities (e.g., seatwork) and avoidance of whole-class activities (e.g., discussion) similarly in both classes. Implications for educational practices and further research are discussed.

    This study aimed at assessing the changes in brain metabolism related to white-matter magnetic resonance (MR) hyperintensities of presumed vascular origin, with a voxel-based quantitative analysis of (18F)-fluorodesoxyglucose positron emission tomography (FDG-PET) imaging. Sixty older hypertensive patients with subjective memory complaints (75 ± 5 years, 34 women) were prospectively referred to FDG-PET and MRI brain imaging. The Statistical Parametric Mapping software was used to assess the correlation between brain distribution of FDG and white-matter hyperintensities assessed by the Fazekas score on MRI images. The Fazekas score was inversely related to FDG uptake, independently of age and gender, within 14 Brodmann areas located mainly in the frontal lobe but also in certain limbic, insular and temporal areas. This relationship was also found to be largely independent of the volume of grey matter expressed in percentage of cranial volume, an index of atrophy. White-matter MR hyperintensities of presumed vascular origin are cross-sectionally associated with a lower grey-matter metabolism, mainly but not only within frontal areas and independently of age, gender and grey-matter atrophy. © 2016 S.

    Mastery, or the feeling of power or control over one's life, is a vital yet understudied covariate of wellbeing in adolescence and adulthood. The goal of the current study was to explore the effects of demographic characteristics (i.e., sex, age, race/ethnicity, and socioeconomic status (SES)), maternal mastery, and supportive-involved mothering on children's mastery at ages 16-17 years. 855 teens (47.6% female) and their mothers provided study data as part of the 1992 and 1998 waves of National Longitudinal Survey of Youth-1979 (NLSY-79; 24.1% Hispanic, 36.6% Black). Hybrid path models indicated that only maternal parenting during middle childhood was linked directly to levels of children's mastery in middle adolescence; a small portion of the association between parenting and adolescent mastery was attributable to SES. The discussion centers on significance of these findings for future research and theory development.

  18. 'The body does matter': Women as embodied social subjects in Angela Carter's Nights at the Circus

    Directory of Open Access Journals (Sweden)

    Milosavljević Tatjana B.

    2017-01-01

    Full Text Available Postmodernism posed a crucial ontological challenge to reality, questioning what constitutes the real world, simultaneously interrogating the horizon of representation of this unstable reality in fiction. Feminism on the other hand equipped us with critical tools for interpreting the reality of being in the world in a gendered body, as well as with a conceptual apparatus for interpreting the manifold institutional and private oppressions of women's bodies that play out in women's daily lives and in the discourses that shape them, literary discourse being one of them. This paper argues that Angela Carter's 1984 novel Nights at the Circus, which is widely held as a postfeminist text due to its narrative commitment to transcending gender binaries, essentially uses the strategies of postmodern storytelling and characterization in order to explore women's embodied potentialities of agency i.e. their construction of subjectivity through body. We will argue that the hybrid magic realist narrative constructs Fevvers' body as a titillating postmodern performance, ontologically illusive and elusive, yet it grounds that same body in various socially effected predicaments and experiences that serve to show that even in the midst of a play of signifiers, in Patricia Waugh's words, 'the body does matter, at least to what has been the dominant perspective within British female fiction' (Waugh, 2006, p. 196. In other words, it may be argued that Carter's novel is invested in traditional second-wave feminist politics to the extent that it shows that a woman's body is an indispensable medium of being in the world with material consequences that bear on the formation of her subjectivity and possibility of agency, and through which she acts out her relationships to others and is acted upon.

  19. NASA's Universe of Learning: The Integral Role of Research Astronomers and Other Subject Matter Experts

    Lee, Janice; Universe of Learning Team

    2018-01-01

    Astronomy seeks to understand the workings of the Universe on its largest scales, and to answer fundamental questions about the story of our origins. The science of astronomy thus naturally lends itself to informal education and public outreach activities, as it broadly captures the human imagination. There are at least three overall goals for investment of resources in Astronomy E/PO: to interest students in pursuing STEM education and careers; to develop Astronomy as context for teaching more basic physical and computer science in service of US National Education Goals; to help motivate continued public support of federally funded Astronomy research and technology development. Providing a full spectrum of opportunities for the public to learn about recent Astronomy discoveries is key to achieving these societal goals. Thus, the E/PO professional community must have an understanding of recent scientific/technological results, and engage with the researchers who are creating new knowledge to explicate that knowledge to the public. It stands to reason that researchers (or “subject matter experts, SMEs”) must be involved in and remain connected to the E/PO endeavor. In this talk, I will describe how research astronomers and other SMEs play an integral role in a full range of informal education programming developed by the NASA Universe of Learning collaboration, and opportunities to get involved.

    Background Methamphetamine (MA) abuse causes damage to structures within the human cerebrum, with particular susceptibility to white matter (WM). Abnormalities have been reported in anterior regions with less evidence of changes in posterior regions. MA abusers have also shown deficits on attention tests that measure response conflict and cognitive control. Methods We examined cognitive control using a computerized measure of the Stroop selective attention task and indices of WM microstructure obtained from diffusion tensor imaging (DTI) in the callosal genu and splenium of 37 currently abstinent MA abusers and 17 non-substance abusing controls. Measurements of Fractional Anisotropy (FA), apparent diffusion coefficient (ADC) of callosal fibers and diffusion tensor eigenvalues were obtained in all subjects. Results The MA abusers exhibited greater Stroop reaction time interference (i.e., reduced cognitive control) [p=.04] compared to controls. After correcting for multiple comparisons, FA within the genu correlated significantly with measures of cognitive control in the MA abusers [p=.04, bonferroni corrected] but not in controls [p=.26]. Group differences in genu, but not splenium, FA were trend significant [p=.09]. Conclusions MA abuse appears to alter anterior callosal WM microstructure with less evidence of change within posterior callosal WM microstructure. DTI indices within the genu, but not splenium, correlated with measures of cognitive control in chronic MA abusers. PMID:18814867

    Full Text Available In this paper, I claim that subjectivity is a way of being that is constituted through a set of practices in which the self is subject to the dangers of fictionalizing and plotting her life and self-image. I examine some ways of becoming subject through narratives and through theatrical performance before others. Through these practices, a real and active subjectivity is revealed, capable of self-knowledge and self-transformation.

    Cortical gray matter volume and resting state cortical electroencephalographic rhythms are typically abnormal in subjects with amnesic mild cognitive impairment (MCI) and Alzheimer's disease (AD). Here we tested the hypothesis that in amnesic MCI and AD subjects, abnormalities of EEG rhythms are a functional reflection of cortical atrophy across the disease. Eyes-closed resting state EEG data were recorded in 57 healthy elderly (Nold), 102 amnesic MCI, and 108 AD patients. Cortical gray matter volume was indexed by magnetic resonance imaging recorded in the MCI and AD subjects according to Alzheimer's disease neuroimaging initiative project (http://www.adni-info.org/). EEG rhythms of interest were delta (2-4 Hz), theta (4-8 Hz), alpha1 (8-10.5 Hz), alpha2 (10.5-13 Hz), beta1 (13-20 Hz), beta2 (20-30 Hz), and gamma (30-40 Hz). These rhythms were indexed by LORETA. Compared with the Nold, the MCI showed a decrease in amplitude of alpha 1 sources. With respect to the Nold and MCI, the AD showed an amplitude increase of delta sources, along with a strong amplitude reduction of alpha 1 sources. In the MCI and AD subjects as a whole group, the lower the cortical gray matter volume, the higher the delta sources, the lower the alpha 1 sources. The better the score to cognitive tests the higher the gray matter volume, the lower the pathological delta sources, and the higher the alpha sources. These results suggest that in amnesic MCI and AD subjects, abnormalities of resting state cortical EEG rhythms are not epiphenomena but are strictly related to neurodegeneration (atrophy of cortical gray matter) and cognition.

  14. Being in a romantic relationship is associated with reduced gray matter density in striatum and increased subjective happiness

    Full Text Available Romantic relationship, a widespread feature of human society, is one of the most influential factors in daily life. Although stimuli related to romantic love or being in a romantic relationship commonly result in enhancement of activation or functional connectivity of the reward system, including the striatum, the structure underlying romantic relationship-related regions remain unclear. Because individual experiences can alter gray matter within the adult human brain, we hypothesized that romantic relationship is associated with structural differences in the striatum related to the positive subjective experience of being in a romantic relationship. Because intimate romantic relationships contribute to perceived subjective happiness, this subjective enhancement of happiness might be accompanied by the experience of positive events related to being in a romantic relationship. To test this hypothesis and elucidate the structure involved, we compared subjective happiness, an indirect measure of the existence of positive experiences caused by being in a romantic relationship, of participants with or without romantic partners (N = 68. Furthermore, we also conducted a voxel-based morphometry (VBM study of the effects of being in a romantic relationship (N = 113. Being in a romantic relationship was associated with greater subjective happiness and reduced gray matter density within the right dorsal striatum. These results suggest that being in a romantic relationship enhances perceived subjective happiness via positive experiences. Furthermore, the observed reduction in gray matter density in the right dorsal striatum may reflect an increase in saliency of social reward within a romantic relationship. Thus, being in a romantic relationship is associated with positive experiences and a reduction of gray matter density in the right dorsal striatum, representing a modulation of social reward.

    Planetary Learning that Advances the Nexus of Engineering, Technology, and Science (PLANETS) was selected as one of 27 new projects to support the NASA Science Mission Directorate's Science Education Cooperative Agreement Notice. Our goal is to develop and disseminate out-of-school time (OST) curricular and related educator professional development modules that integrate planetary science, technology, and engineering. We are a partnership between planetary science Subject Matter Experts (SMEs), curriculum developers, science and engineering teacher professional development experts and OST teacher networks. The PLANETS team includes the Center for Science Teaching and Learning (CSTL) at Northern Arizona University (NAU); the U.S. Geological Survey (USGS) Astrogeology Science Center (Astrogeology), and the Boston Museum of Science (MOS). Here, we present the work and approach by the SMEs at Astrogeology. As part of this overarching project, we will create a model for improved integration of SMEs, curriculum developers, professional development experts, and educators. For the 2016 and 2017 Fiscal Years, our focus is on creating science material for two OST modules designed for middle school students. We will begin development of a third module for elementary school students in the latter part of FY2017. The first module focuses on water conservation and treatment as applied on Earth, the International Space Station, and at a fictional Mars base. This unit involves the science and engineering of finding accessible water, evaluating it for quality, treating it for impurities (i.e., dissolved and suspended), initial use, a cycle of greywater treatment and re-use, and final treatment of blackwater. The second module involves the science and engineering of remote sensing as it is related to Earth and planetary exploration. This includes discussion and activities related to the electromagnetic spectrum, spectroscopy and various remote sensing systems and techniques. In

  1. Methods to model particulate matter clarification of unit operations subject to unsteady loadings.

    Spelman, David; Sansalone, John J

    2017-05-15

    Stormwater, and also wastewater unit operations (UOs) to a much lower extent, are subject to unsteady hydrodynamic and particulate matter (PM) fluxes. Simulating fully transient clarification of hetero-disperse PM requires much greater computational expense compared to steady simulations. An alternative to fully unsteady methods are stepwise steady (SS) methods which use stepwise steady flow transport and fate to approximate unsteady PM clarification of a UO during transient hydraulic loadings such as rainfall-runoff. The rationale is reduced computational effort for computational fluid dynamics (CFD) compared to simulating continuous unsteadiness of such events. An implicit solution stepwise steady (IS3) method is one approach which builds upon previous SS methods. The IS3 method computes steady flows that are representative of unsteady PM transport throughout an unsteady loading. This method departs from some previous SS methods that assume PM fate can be simulated with an instantaneous clarifier (basin) influent flowrate coupled with a PM input. In this study, various SS methods were tested for basins of varying size and residence time to examine PM fate. Differences between SS methods were a function of turnover fraction indicating the role of unsteady flowrates on PM transport for larger basins of longer residence times. The breakpoint turnover fraction was between two and three. The IS3 method best approximated unsteady behavior of larger basins. These methods identified limitations when utilizing standard event-based loading analysis for larger basins. For basins with a turnover fraction less than two, the majority of effluent PM did not originate from the event-based flow; originating from previous event loadings or existing storage. Inter- and multiple event processes and interactions, that are dependent on this inflow turnover fraction, are not accounted for by single event-based inflow models. Results suggest the use of long-term continuous modeling

The research study titled Integrating Multicultural Subject Matters into Teaching Strategies of Elementary School Teachers (The U.S. State of Kansas, conducted in 2007 based on a sample of 89 elementary school teachers in the U.S. State of Kansas, represents one aspect of assessing the adequacy of undergraduate education regarding multicultural subject matters for elementary school teachers in Slovenia and the U.S. (State of Kansas as well as the qualifications of elementary school teachers of both countries for working with immigrant children. Despite the long-standing tradition of multicultural education in western countries, the research results for Kansas elementary school teachers showed a presence of significant discrepancies between the actual and optimal integration of multicultural subject matters. These results indicate that future undergraduate study programs will have to invest more time in developing multicultural skills and providing practical experiences for working in a diverse environment.

    manager finds the advisory to be operationally appropriate, he or she would coordinate with the Area Supervisor(s) of the sectors that currently control the flights in the advisory. When the traffic manager accepts the MFCR advisory via the user interface, the corresponding flight plan amendments would be sent to the displays of the appropriate sector controllers, using the Airborne Re-Routing (ABRR) capability which is scheduled for nationwide operation in 2017. The sector controllers would then offer this time-saving route modification to the pilots of the affected flights via datalink (or voice), and implement the corresponding flight plan amendment if the pilots accept it. MFCR is implemented as an application in the software environment of the Future Air traffic management Concepts Evaluation Tool (FACET). This paper focuses on an initial subject matter expert (SME) evaluation of MFCR. The evaluation covers MFCRs operational concept, algorithm, and user interface.

    Full Text Available Old age is commonly associated with loneliness as loss of partner and friends, retirement, deteriorating health and functional impairments may make way for loneliness. An ageing population may give rise to concern for growing numbers of lonely people. The study explores loneliness among older people 67-79 years old (N=699, living in their own homes, examining whether and how socio-demographic factors, subjective health, and mastery influence loneliness among people with no impairments and people with impairments. The study uses cross-sectional and longitudinal (five-year panel data from the Norwegian Life Course, Ageing and Generation study (NorLAG, calculating the risk of loneliness at T1, and prospectively at T2. Mastery is the only factor significantly influencing the risk of loneliness both at T1 and T2, both for older people with impairments and for those without impairments. A high level of mastery is related to a lower risk of loneliness. Being married or cohabitant are related to a lower risk of loneliness, among those without impairments both at T1 and at T2, among those with impairments only at T1. Age, gender and subjective health were not independently related to loneliness at any time. The results suggest that the subjective feeling of mastery is important to avoid loneliness, both at T1 and prospectively at T2 in both groups

    For given levels of psychoactive substance use, symptoms of substance use disorder (SUD) can vary widely. The concept of addiction resistance (AR) seeks to capture this variation so we can understand its causes. In a population-based twin sample, AR was defined as the deviation in the number of reported SUD criteria for a given substance from that predicted from the level of maximal consumption. Therefore, subjects with strong AR demonstrate few symptoms of SUD even at high levels of consumption. Twin modeling was performed by Mx. We assessed AR for alcohol, nicotine and cannabis. Heritability was assessed at two occasions thereby correcting for measurement error and ranged from 35 to 52% with no evidence for shared environment. ARs for alcohol, nicotine and cannabis were relatively stable over time and were substantially predicted by parental history of SUD, early adversity, comorbidity with both internalizing and externalizing disorders, personality and especially by the trait of mastery. AR, which assesses individual variation in sensitivity to the development of SUD for a given level of drug exposure, may be a useful concept for addiction research. As applied to common psychoactive substances, AR is moderately heritable, relatively stable and predicted by family history, comorbidity and personality. The relationship with mastery is of particular interest in that it may reflect an ability to resist the progression of the addictive process into key life domains and to avoid loss of control of intake, even when consuming at high levels.

    Full Text Available Teaching vocabulary using textbooks is sometimes boring and less meaningful due to the lack of context that possibly discourages students to learn. At university level, students are supposed to acquire intermediate to upper level of vocabulary mastery. The situation then becomes a challenge for us to cope. Authentic materials, on the other hand provide real language use which can be positively stimulate students’ interest to have sufficient exposure to English. This research is aimed at improving students’ vocabulary mastery through written authentic materials. The design of the research is classroom action research. It was conducted in a Vocabulary Building class B consisting of 43 students. The selected authentic materials are texts taken from newspaper, magazine, the internet, recipe, & forms. The result of the study shows that through authentic materials the students’ vocabulary mastery in cycle I & II improves and the achievement category is sufficient. Otherwise, students’ response towards the use of authentic texts seems increase significantly from cycle I to cycle II.

    In social-cognitive theory, it is hypothesized that mastery experiences (successfully implementing behaviour change) are a source of self-efficacy, and self-efficacy increases the opportunity for experiencing mastery. Vicarious experiences (seeing others succeed) are suggested as another source of self-efficacy. However, the hypothesis of this reciprocal relationship has not been tested using a day-to-day design. This article reports findings from two intensive longitudinal studies, testing the reciprocal relationship of self-efficacy and its two main sources within the naturally occurring process of quitting smoking (without intervention). Smokers (Study 1: N = 100 smokers in smoker-non-smoker couples (1,787 observations); Study 2; N = 81 female (1,401 observations) and N = 79 male smokers (1,328 observations) in dual-smoker couples) reported their mastery experiences (not smoking the entire day; in Study 2, mastery experience of partner served as vicarious experience) and smoking-specific self-efficacy for 21 days after a self-set quit date. Time-lagged multilevel analyses were conducted using change-predicting-change models. Increases in mastery experiences predicted changes in self-efficacy, and increases in self-efficacy predicted changes in mastery experiences in Study 1. Study 2 replicated these results and showed contagion effects (partners' mastery on individuals' mastery and partners' self-efficacy on individuals' self-efficacy), but found no evidence for a link between vicarious experiences (partners' mastery experiences) and individuals' self-efficacy. This article demonstrates that mastery experiences and self-efficacy show a reciprocal relationship within smokers during a quit attempt in a day-to-day design, as well as contagion effects in couples when both partners try to quit simultaneously. Statement of Contribution What is already known on this subject? Self-efficacy is one of the strongest correlates of quitting smoking. Despite the

    Full Text Available The bromatological composition and in vitro dry matter digestibility of millet cultivars were assessed for different nitrogen doses and two sowing seasons in the Ceres municipality of Goiás state, Brazil. The treatments consisted of three millet cultivars (ADR-7010, ADR-500 and BRS-1501, four nitrogen (N doses (0, 50, 100 and 200kg ha-1 of N and two sowing seasons. Three replicates and a randomised block design with a 3 x 4 x 2 factorial scheme were used. Two cuttings were performed in each season when plants reached an average height of 0.70 cm. No significant interactions were observed between or among cultivars for N doses and dry matter (DM, crude protein (CP, neutral detergent fibre (NDF and acid detergent fibre (ADF contents. The DM, CP, NDF and ADF contents were significantly different between N doses. The DM and CP contents increased as the N dose increased to 100kg ha-1. The maximum DM and CP contents were 11.14 and 22.53%, respectively. The NDF and ADF contents were higher in the control treatment (60.11 and 30.01%, respectively. In addition, the lowest ADF and NDF concentrations occurred at an N dose of 50kg ha-1 (56.33 and 30.23%, respectively. The DM contents were higher for the February sowing, with an average of 10.59%. The highest CP and ADF contents were found for the December sowing (22.46 and 31.58%, respectively. No significant differences were found for millet cultivars, N doses or sowing seasons. A significant interaction was found between sowing season and millet cultivar. The BRS-1501 cultivar had a higher in vitro dry matter digestibility in the December/2010 sowing (73.88%.

    Structural imaging based on MRI is an integral component of the clinical assessment of patients with potential dementia. We here propose an individualized Gaussian process-based inference scheme for clinical decision support in healthy and pathological aging elderly subjects using MRI. The approach aims at quantitative and transparent support for clinicians who aim to detect structural abnormalities in patients at risk of Alzheimer's disease or other types of dementia. Firstly, we introduce a generative model incorporating our knowledge about normative decline of local and global gray matter volume across the brain in elderly. By supposing smooth structural trajectories the models account for the general course of age-related structural decline as well as late-life accelerated loss. Considering healthy subjects' demography and global brain parameters as informative about normal brain aging variability affords individualized predictions in single cases. Using Gaussian process models as a normative reference, we predict new subjects' brain scans and quantify the local gray matter abnormalities in terms of Normative Probability Maps (NPM) and global z-scores. By integrating the observed expectation error and the predictive uncertainty, the local maps and global scores exploit the advantages of Bayesian inference for clinical decisions and provide a valuable extension of diagnostic information about pathological aging. We validate the approach in simulated data and real MRI data. We train the GP framework using 1238 healthy subjects with ages 18-94 years, and predict in 415 independent test subjects diagnosed as healthy controls, Mild Cognitive Impairment and Alzheimer's disease.

    Dysregulation of emotional arousal is observed in many psychiatric diseases such as schizophrenia, mood and anxiety disorders. The neurotrophic tyrosine kinase receptor type 2 gene (NTRK2) has been associated with these disorders. Here we investigated the relation between genetic variability of NTRK2 and emotional arousal in healthy young subjects in two independent samples (n1=1171; n2=707). In addition, diffusion tensor imaging (DTI) data in a subgroup of 342 participants were used to identify NTRK2-related white-matter structure differences. After correction for multiple testing, we identified a NTRK2 single nucleotide polymorphism associated with emotional arousal in both samples (n1: Pnominal=0.0003, Pcorrected=0.048; n2: Pnominal=0.0141, Pcorrected=0.036). DTI revealed significant, whole-brain corrected correlations between emotional arousal and brain white-matter mean diffusivity (MD), as well as significant, whole-brain corrected NTRK2 genotype-related differences in MD (PFWE<0.05). Our study demonstrates that genetic variability of NTRK2, a susceptibility gene for psychiatric disorders, is related to emotional arousal and—independently—to brain white-matter properties in healthy individuals.

    Two key variables emerged from the literature review is that Specific Matter Knowledge [SMK] and Pedagogical Content Knowledge [PCK] can influence the mathematics teachers' Professional Development [PD] needs. However, the key variables of SMK and PCK that were being investigated were not defined clearly. Empirical evidence that support relationship between SMK and PD and PCK and PD were not verified. In addition, how does PCK mediate SMK and PD is not clear and somewhat lacking. Therefore, the purpose of this paper was to examine the relationship between primary mathematics teacher's SMK, PCK and PD needs. Results of path analysis with SmartPLS indicated that the direct effect of SMK on PD was mediated via PCK. This data provide support for the claim that PD programs for future teachers of primary mathematics should be driven by a more nuanced understanding of the link between SMK and PCK.

    An important aspect of the study of brain function involves measurement of the relationships; between activities in the subcortical gray matter of the caudate and of the thalamus; and between these structures and functional cortical areas. The authors have studied these relationships in 22 subjects under different conditions of activation, sleep and sensory deprivation using a PET VI system and F-18-2DG to determine regional cerebral metabolism. Subject activating conditions were maintained throughout the period of equilibration of F-18-2DG and E.E.G.'s were monitored. Multiple tomographic slices of 1-2 million counts were obtained simultaneously with slice separation of 14mm and each plane parallel to the cantho-meatal line. In activated and non-activated awake conditions for normal subjects, left and right thalmus-to-caudate ratios were similar and greater than unity. This relationship was maintained in non-REM sleep, but was reversed and divergent in REM sleep and sensory deprivation; this was also evident in 3/4 narcoleptics awake and asleep in non-REM and REM and 2/3 schizophrenics and affective disorder, subjects. This approach appears to have potential for characterizating normal and disordered regional cerebral function.

    Dissolved organic matter (DOM) is the most bioavailable soil organic pool. Understanding how DOM responds to elevated temperature is important for forecasting soil carbon (C) dynamics under climate warming. Here a 4.5-year field microcosm experiment was carried out to examine temporal DOM concentration dynamics in soil pore-water from six different subtropical wetlands. Results are compared between control (ambient temperature) and warmed (+5°C) treatments. UV-visible and fluorescence spectroscopy was performed to reveal DOM structural complexity at the end of the warming incubation. Elevated temperature resulted in initially (1 to 2.5 years) high pore-water DOM concentrations in warmed samples. These effects gradually diminished over longer time periods. Of the spectral indices, specific UV absorbance at 280 nm and humification index were significantly higher, while the signal intensity ratio of the fulvic-like to humic-like fluorescence peak was lower in warmed samples, compared to the control. Fluorescence regional integration analysis further suggested that warming enhanced the contribution of humic-like substances to DOM composition for all tested wetlands. These spectral fingerprints implied a declined fraction of readily available substrates in DOM allocated to microbial utilization in response to 4.5 years of warming. As a negative feedback, decreased DOM biodegradability may have the potential to counteract initial DOM increases and alleviate C loss in water-saturated wetland soils. © 2013.

    2009-01-01

    Full Text Available Abstract: The teaching of ESP so far has been dominated by the belief that linguistic mastery of English is considered sufficient to deliver the contents of the subject matter concerned. This view seems to need a critical overview for verbal communication in general, let alone in ESP, requires both proficiency in the language and the contents. This implies that English teachers in ESP need to be equipped satisfactorily in English as well as the subject matter. An ESP teacher needs to possess a double competency. With this as a framework, the teaching of ESP accordingly will need to shift its focus from English in isolation to English as medium for subject matters exchanges.

    In this response to Konstantinos Alexakos, Jayson K. Jones, and Victor H. Rodriguez's study, I discuss ways attending to student membership in groups can both inform research on equity and diversity in science education and improve the teaching of science to all students. My comments are organized into three sections: how underrepresented students' experiences in science classrooms are shaped by their peers; how science teachers can help students listen to and learn from one another; and how the subject matter can invite or discourage student participation in science. More specifically, I underscore the need for teachers and students to listen to one another to promote student learning of science. I also highlight the importance of science education researchers and science teachers viewing students both as individuals and as members of multiple groups; women of color, for example, should be understood as similar to and different from each other, from European American women and from ethnic minorities in general.

    AV-45 amyloid biomarker is known to show uptake in white matter in patients with Alzheimer's disease (AD), but also in the healthy population. This binding, thought to be of a non-specific lipophilic nature, has not yet been investigated. The aim of this study was to determine the differential pattern of AV-45 binding in white matter in healthy and pathological populations. We recruited 24 patients presenting with AD at an early stage and 17 matched, healthy subjects. We used an optimized positron emission tomography-magnetic resonance imaging (PET-MRI) registration method and an approach based on an intensity histogram using several indices. We compared the results of the intensity histogram analyses with a more canonical approach based on target-to-cerebellum Standard Uptake Value (SUVr) in white and grey matter using MANOVA and discriminant analyses. A cluster analysis on white and grey matter histograms was also performed. White matter histogram analysis revealed significant differences between AD and healthy subjects, which were not revealed by SUVr analysis. However, white matter histograms were not decisive to discriminate groups, and indices based on grey matter only showed better discriminative power than SUVr. The cluster analysis divided our sample into two clusters, showing different uptakes in grey, but also in white matter. These results demonstrate that AV-45 binding in white matter conveys subtle information not detectable using the SUVr approach. Although it is not more efficient than standard SUVr in discriminating AD patients from healthy subjects, this information could reveal white matter modifications. (orig.)

    Cerebral white matter lesions (WMLs) are radiologic markers of small vessel disease in brain, and inflammatory processes were related to WMLs. We propose to determine if elevated leukocyte count was associated with a higher risk of WMLs. 1586 asymptomatic subjects who visited our hospital for a routine health check-up were enrolled. Leukocyte counts were measured and the presence of moderate to severe WMLs was determined by brain MRI. Thirty (1.9%) had moderate to severe WMLs, and a significant greater proportion (4.1%) of subjects in the highest leukocyte count quartile had moderate to severe WMLs. After adjusting by C-reactive protein, aspirin use and cardiovascular risk factors, the highest quartile of leukocyte count (≥6.7×10⁹/L) was significantly associated with moderate to severe WMLs compared with the lowest quartile [adjusted odds ratio, 4.03; 95% confidence interval, 1.05-15.5]. The authors report for the first time that an elevated leukocyte count is independently associated with moderate to severe WMLs. Copyright © 2010. Published by Elsevier B.V.

  10. NPY mRNA Expression in the Prefrontal Cortex: Selective Reduction in the Superficial White Matter of Subjects with Schizoaffective Disorder

    Morris, Harvey M.; Stopczynski, Rachelle E.; Lewis, David A.

    2009-01-01

    Background Alterations in the inhibitory circuitry of the dorsolateral prefrontal cortex (DLPFC) in schizophrenia include reduced expression of the messenger RNA (mRNA) for somatostatin (SST), a neuropeptide present in a subpopulation of γ-aminobutyric acid (GABA) neurons. Neuropeptide Y (NPY) is expressed in a subset of SST-containing interneurons and lower levels of NPY mRNA have also been reported in schizophrenia spectrum disorders. However, whether the alterations in these two transcripts identify the same, particularly vulnerable, subset of GABA neurons has not been examined. Methods We used in situ hybridization to quantify NPY mRNA levels in DLPFC gray and white matter from 23 pairs of subjects with schizophrenia or schizoaffective disorder and matched normal control subjects; results were compared to those from a previous study of SST mRNA expression in the same subjects. Results In contrast to SST mRNA, NPY mRNA levels were not significantly lower in the gray matter of subjects with schizophrenia or schizoaffective disorder. However, NPY, but not SST, mRNA expression was significantly lower in the superficial white matter of subjects with schizoaffective disorder. Conclusion These findings suggest that the alterations in SST-containing interneurons in schizophrenia and schizoaffective disorder are selective for the subset that do not express NPY mRNA, and that lower NPY mRNA expression in the superficial white matter may distinguish subjects with schizoaffective disorder from those with schizophrenia.

    The desire to be good at one's work grows out of the aspiration, competition, and a yearning to be the best. Surgeons, in their aim to provide the best care possible to their patients, adopt this behavior to achieve high levels of expert performance through mastery learning, and the surgical training attempts to prepare them optimally to lead a virtuous and productive life. The proponents of the framework reject evidence that suggests that other variables are also necessary to achieve high levels of expert performance. Here, we review various models and designs to achieve mastery along with their pros and cons to help us understand how mastery learning is helpful in surgical practice.

  14. DNA as patentable subject matter and a narrow framework for addressing the perceived problems caused by gene patents.

    Science.gov (United States)

    Schilling, Stephen H

    2011-12-01

    Concerns about the alleged harmful effects of gene patents--including hindered research and innovation and impeded patient access to high-quality genetic diagnostic tests--have resulted in overreactions from the public and throughout the legal profession. These overreactions are exemplified by Association for Molecular Pathology v. U.S. Patent and Trademark Office, a 2010 case in the Southern District of New York that held that isolated DNA is unpatentable subject matter under 35 U.S.C. § 101. The problem with these responses is that they fail to adequately consider the role that gene patents and patents on similar biomolecules play in facilitating investment in the costly and risky developmental processes required to transform the underlying inventions into marketable products. Accordingly, a more precisely refined solution is advisable. This Note proposes a narrowly tailored set of solutions to address the concerns about gene patents without destroying the incentives for companies to create and commercialize inventions derived from these and similar patents.

  15. Developing Pedagogical Content Knowledge for Teaching a New Topic: More Than Teaching Experience and Subject Matter Knowledge

    Science.gov (United States)

    Chan, Kennedy Kam Ho; Yung, Benny Hin Wai

    2017-03-01

    Teaching experience has been identified as an important factor in pedagogical content knowledge (PCK) development. However, little is known about how experienced teachers may draw on their previous experience to facilitate their PCK development. This study examined how two experienced high school biology teachers approached the teaching of a newly introduced topic in the curriculum, polymerase chain reaction and their PCK development from the pre-lesson planning phase through the interactive phase to the post-lesson reflection phase. Multiple data sources included classroom observations, field notes, semi-structured interviews and classroom artefacts. It was found that the teachers' previous experience informed their planning for teaching the new topic, but in qualitatively different ways. This, in turn, had a bearing on their new PCK development. Subject matter knowledge (SMK) can not only facilitate but may also hinder this development. Our findings identify two types of experienced teachers: those who can capitalise on their previous teaching experiences and SMK to develop new PCK and those who do not. The critical difference is whether in the lesson planning stage, the teacher shows the disposition to draw on a generalised mental framework that enables the teacher to capitalise on his existing SMK to develop new PCK. Helping teachers to acquire this disposition should be a focus for teacher training in light of continuous curriculum changes.

  17. Promoting mastery of complex biological mechanisms.

    Bradshaw, William S; Groneman, Kathryn J; Nelson, Jennifer; Bell, John D

    2017-09-13

    This article describes efforts aimed at improving comprehension and retention of complex molecular mechanisms commonly studied in undergraduate biology and biochemistry courses. The focus is on the design of appropriate assessments, an active classroom emphasizing formative practice, and more effective out-of-class study habits. Assessments that require students to articulate their understanding through writing are the most effective. Frequent formative practice improves performance on problems that require intellectual transfer, the ability to apply conceptual principles in novel settings. We show that success with such problems is a function of mastery of the intrinsic logic of the biology in play, not variations in the way they are written. Survey data demonstrate that many students would prefer a learning style not dominated by memorization of factual details, but how to develop a more effective strategy is rarely intuitive. Matching individual students with specific learning styles has not proven useful. Instead, teachers can strongly promote individual metacognitive appraisal during both classroom activities and other study environments. © 2017 by The International Union of Biochemistry and Molecular Biology, 2017. © 2017 The International Union of Biochemistry and Molecular Biology.

  18. Structuring feedback and debriefing to achieve mastery learning goals.

    Mastery learning is a powerful educational strategy in which learners gain knowledge and skills that are rigorously measured against predetermined mastery standards with different learners needing variable time to reach uniform outcomes. Central to mastery learning are repetitive deliberate practice and robust feedback that promote performance improvement. Traditional health care simulation involves a simulation exercise followed by a facilitated postevent debriefing in which learners discuss what went well and what they should do differently next time, usually without additional opportunities to apply the specific new knowledge. Mastery learning approaches enable learners to "try again" until they master the skill in question. Despite the growing body of health care simulation literature documenting the efficacy of mastery learning models, to date insufficient details have been reported on how to design and implement the feedback and debriefing components of deliberate-practice-based educational interventions. Using simulation-based training for adult and pediatric advanced life support as case studies, this article focuses on how to prepare learners for feedback and debriefing by establishing a supportive yet challenging learning environment; how to implement educational interventions that maximize opportunities for deliberate practice with feedback and reflection during debriefing; describing the role of within-event debriefing or "microdebriefing" (i.e., during a pause in the simulation scenario or during ongoing case management without interruption), as a strategy to promote performance improvement; and highlighting directions for future research in feedback and debriefing for mastery learning.

    2016-12-01

    CosmoQuest is a virtual research facility, which, like its physical counterparts, provides tools for scientists to acquire reduced data products (thanks to our cadre of citizen scientists working to analyze images and produce results online), and also to participate in education and outreach activities either directly through CosmoQuest activities (such as CosmoAcademy and the Educators' Zone) or with the support of CosmoQuest. Here, we present our strategies to inspire, engage and support Subject Matter Experts (SMEs - Scientists, Engineers, Technologists and Mathematicians) in activities outside of their institutions, and beyond college classroom teaching. We provide support for SMEs who are interested in increasing the impacts of their science knowledge and expertise by interacting with people online, or in other venues outside of their normal work environment. This includes a broad spectrum of opportunities for those interested in hosting webinars; running short courses for the public; using Facebook, Twitter or other social media to communicate science; or other diverse activities such as supporting an open house, science fair, or star party. As noted by Katheryn Woods-Townsend and colleagues, "...face-to-face interactions with scientists allowed students to view scientists as approachable and normal people, and to begin to understand the range of scientific areas and careers that exist. Scientists viewed the scientist-student interactions as a vehicle for science communication" (2015). As CosmoQuest fosters these relationships, it We present a framework for SMEs which combine opportunities for continuing professional development (virtually and in person at conferences) with ongoing online support, creating a dynamic professional learning network. The goal of this is to deepen SME capacity-knowledge, attitudes and behaviors-both encouraging and empowering them to connect to broader audiences in new ways.

    2015-02-01

    Full Text Available Narrated animated solution videos were implemented in a clinical study that compared a mastery setting that employed repeated cycles of testing with instructional support to a group that had a single opportunity to experience the materials. The mastery setting students attempted sequential questions sets on a topic, with animated solutions between each set, until mastery was achieved, combining formative assessment with worked examples. Students showed significant improvement from their first to second tries on similar sets of problems, attributable to the feedback and solutions they were given after the first try. These improvements were shown in two topics, superposition and electric potential. The single try group was given one version of the questions and solutions, and while they were not required to watch the solutions to move forward, they chose to. On a post-test including near and far transfer questions, no significant difference was seen between the mastery group and the single try group, but both significantly outperformed a control group that received no instructional support, indicating that students successfully transferred the skills from the solutions to the post-test.

    2012-01-01

    In Polish society, for some time now, a growing interest in supplementation of the diet has been observed. This problem addresses particularly to sportsmen and physically active persons. It is often due to belief that customary diet does not supply organism with necessary food ingredients. There are also some threats connected with supplementation of the diet. Problems addressed to supplementation of the diet are particularly important for young sportsmen, including students of sport mastery schools. The aim of the study was the evaluation of the diet supplementation used by the students of sport mastery school in Western Pomeranian district. The study was carried out in the group of 76 students, aged 15 to 19, practicing walleyball (girls n = 39) and football (boys n = 37) at the sport mastery school in Police (western Pomeranian district). The interview method has been applied. A significance of differences, for the analysed factor, due to a sport discipline practiced was calculated based on Chi2 (Statistica 9). The results of the study confirmed the students of sport mastery school to supplement their diets. The diet supplementation being more frequent for boys (67.6%) with magnesium (57-64%) noted as the most frequently used supplement, followed with vitamin-mineral agents and L-carnitine. Essential differences were noted for reasons of diet supplementation and sources of information used on supplements between the sport disciplines practiced. It can be stated, based on the obtained results, that for supplementation of the diet among students of sport mastery school in Police is popular, even though there was no previous recognition of its necessity. The most frequent supplements users were football players with magnesium being the most frequently chosen supplement. Based on the above a regular training of sportsmen, including also coaches training young people, on the rational feeding habits would be advisable.

    Dimethyl fumarate (DMF) is an oral treatment for relapsing-remitting multiple sclerosis (MS) with anti-inflammatory and possible neuroprotective properties. Its effect on white matter and gray matter pathology is still not fully understood. The aim of the study was to characterize the effect of DMF on normal-appearing white matter (NAWM) and thalamic pathology longitudinally. In this observational, longitudinal, 24-month magnetic resonance imaging study, 75 patients with relapsing-remitting MS treated with DMF and 40 age- and sex-matched healthy individuals were enrolled. Regional diffusion tensor imaging metrics and tract-based spatial statistics analyses were used to assess differences between groups. Mean diffusivity, axial diffusivity, radial diffusivity and fractional anisotropy were measured in the thalamus and NAWM. Baseline differences and changes over time were evaluated within and between study groups. At baseline, patients with MS showed significantly increased diffusivity and decreased fractional anisotropy in the thalamus (P < 0.001 for mean diffusivity, axial diffusivity and radial diffusivity) and NAWM (all P < 0.016) compared with healthy individuals. No significant within-group difference was found in diffusion tensor imaging measures over 24 months in either group. Healthy individuals showed a significantly greater rate of increased diffusivity parameters in the thalamus and NAWM compared with patients with MS, over 24 months (P < 0.05). The lack of changes in diffusion tensor imaging metrics in patients with MS over 24 months possibly indicates a neuroprotective role of DMF. These findings provide additional evidence of the beneficial effect of DMF on MS-related pathology. © 2018 EAN.

  10. Analysis of self-directed mastery learning of honors physics

    Athens, Wendy

    Self-directed learning (SDL) is an important life skill in a knowledge-based society and prepares students to persist, manage their time and resources, use logic to construct their knowledge, argue their views, and collaborate. The purpose of this study was to facilitate mastery of physics concepts through self-directedness in formative testing with feedback, a choice of learning activities, and multiple forms of support. This study was conducted within two sections of honors physics at a private high school (N=24). Students' learning activity choices, time investments, and perceptions (assessed through a post survey) were tracked and analyzed. SDL readiness was linked to success in mastering physics concepts. The three research questions pursued in this study were: What SDL activities did honors physics students choose in their self-directed mastery learning environment? How many students achieved concept mastery and how did they spend their time? Did successful and unsuccessful students perceive the self-directed mastery learning environment differently? Only seven of 24 students were successful in passing the similar concept-based unit tests within four tries, and these seven students were separated into a "successful" group and the other 17 into an "unsuccessful" group. Differences between the two groups were analyzed. A profile of a self-directed secondary honors physics student emerged. A successful self-directed student invested more time learning from activities rather than simply completing them, focused on learning concepts more than rote operations, intentionally selected activities to fill in gaps of knowledge and practice concepts, actively constructed knowledge into a cognitive framework, engaged in academic discourse with instructor and peers as they made repeated attempts to master content and pass the test given constructive feedback, used a wide variety of learning resources, and managed their workload to meet deadlines.

    Full Text Available Background: Self-mastery is an important psychological resource to cope with stressful situations. However, we have limited understanding of self-mastery among minority aging populations. Objective: This study aims to examine the presence and levels of self-mastery among U.S. Chinese older adults. Methods: Data were drawn from the PINE study, a population-based survey of U.S. Chinese older adults in the Greater Chicago area. Guided by a community-based participatory research approach, a total of 3,159 Chinese older adults aged 60 and above were surveyed. A Chinese version of the Self-Mastery Scale was used to assess self-mastery. Results: Out of the 7-item Chinese Self-Mastery Scale, approximately 42.8% to 87.5% of Chinese older adults experienced some degree of self-mastery in their lives. Older adults with no formal education and the oldest-old aged 85 and over had the lowest level of self-mastery in our study. A higher mastery level was associated with being married, having fewer children, better self-reported health status, better quality of life, and positive health changes. Conclusion: Although self-mastery is commonly experienced among the Chinese aging population in the Greater Chicago area, specific subgroups are still vulnerable. Future longitudinal studies are needed to improve the understanding of risk factors and outcomes associated with self-mastery among Chinese older adults.

    2015-09-01

    This article extends the conceptual knowledge of average relative subjective age in organizations by exploring organizational-level antecedents and consequences of employees, on average, feeling younger than their chronological age. We draw from the theories of selection-optimization-compensation and socioemotional selectivity to build a theoretical framework for relative subjective age in organizations. We hypothesize that companies in which employees, on average, perceive themselves to be younger than they actually are have a higher average individual goal accomplishment and, in turn, experience higher company performance. We further hypothesize that employees' average experience of high work-related meaning relates to a lower subjective age in organizations. In addition, we assess the role of environmental dynamism and age-inclusive human resource management as moderators in this theoretical model. Through empirically testing this model in a multisource dataset, including 107 companies with 15,164 participating employees, we received support for the hypothesized relationships. Our results contribute to current debates in the scientific literature on age and have important practical implications in light of the demographic changes faced by many companies. This research indicates to both researchers and practitioners that it is not employees' chronological age but their subjective age, a factor that can be influenced, which drives organizational performance outcomes.

    Abstract We investigated the relationships between gray matter graph properties and cognitive impairment in a sample of 215 patients with Alzheimer's disease (AD) and also whether age of disease onset modifies such relationships. We expected that more severe cognitive impairment in AD would be related to more random graph topologies. Single-subject gray matter graphs were constructed from T1-weighted magnetic resonance imaging scans. The following global and local graph properties were calculated: betweenness centrality, normalized clustering coefficient γ, and normalized path length λ. Local clustering, path length, and betweenness centrality measures were determined for 90 anatomically defined areas. Regression models with as interaction term age of onset (i.e., early onset when patients were ≤65 years old and late onset when they were >65 years old at the time of diagnosis)×graph property were used to assess the relationships between cognitive functioning in five domains (memory, language, visuospatial, attention, and executive). Worse cognitive impairment was associated with more random graphs, as indicated by low γ, λ, and betweenness centrality values. Three interaction effects for age of onset×global graph property were found: Low γ and λ values more strongly related to memory impairment in early-onset patients; low beta values were significantly related to impaired visuospatial functioning in late-onset patients. For the local graph properties, language impairment showed the strongest relationship with decreased clustering coefficient in the left superior temporal gyrus across the entire sample. Our study shows that single-subject gray matter graph properties are associated with individual differences in cognitive impairment.

    To develop a methodology for a reliable, valid annual skills mastery assessment examination to provide formative student feedback, inform curricular review, and comply with the Accreditation Council for Pharmacy Education (ACPE) Standards 2007. A sample of program-level ability-based outcomes skills were chosen for the examination. Test items were written, underwent quality control, and were scored for level of difficulty. Versions of the examination for first-, second-, third-, and fourth-year pharmacy students were developed and administered, the results were analyzed, reliability and validity were evaluated, and reports were generated. Item-writing guidelines, quality control procedures, and examination production steps were codified to create a criterion-referenced examination. Students and faculty advisors received detailed score reports and results were used to guide student performance and stimulate a review of curricular outcomes. Content, criterion, and construct validity were analyzed as defined in the literature for the intended use of this assessment tool. Data suggest the Annual Skills Mastery Assessment (ASMA) examination is both reliable and valid. Students and faculty members were surveyed regarding the usefulness of the examination. Results indicate general satisfaction with the assessment program. A reasonably reliable, reasonably valid multiple-choice annual skills mastery assessment for selected outcomes statements providing formative feedback and informed curricular review was developed.

    Full Text Available Following current prognosis, demographic development raises expectations of an aging of the working population. Therefore, keeping employees healthy and strengthening their ability to work, becomes more and more important. When employees become older, dealing with age-related impairments of sensory functions, such as hearing impairment, is a central issue. Recent evidence suggests that negative effects that are associated with reduced hearing can have a strong impact at work. Especially under exhausting working situations such as working overtime hours, age and hearing impairment might influence employees’ well-being. Until now, neither the problem of aged workers and long working hours, nor the problem of hearing impairment and prolonged working time has been addressed explicitly. Therefore, a laboratory study was examined to answer the research question: Do age and hearing impairment have an impact on psychophysiological and subjective effects of long working hours. In total, 51 white-collar workers, aged between 24 and 63 years, participated in the laboratory study. The results show no significant effects for age and hearing impairment on the intensity of subjective consequences (perceived recovery and fatigue, subjective emotional well-being and physical symptoms of long working hours. However, the psychophysiological response (the saliva cortisol level to long working hours differs significantly between hearing impaired and normal hearing employees. Interestingly, the results suggest that from a psychophysiological point of view long working hours were more demanding for normal hearing employees.

    Alzheimer disease is a prevalent neurodegenerative disease. Computer assessment of brain atrophy patterns can help predict conversion to Alzheimer disease. Our aim was to assess the prognostic efficacy of individual-versus-combined regional volumetrics in 2 commercially available brain volumetric software packages for predicting conversion of patients with mild cognitive impairment to Alzheimer disease. Data were obtained through the Alzheimer's Disease Neuroimaging Initiative. One hundred ninety-two subjects (mean age, 74.8 years; 39% female) diagnosed with mild cognitive impairment at baseline were studied. All had T1-weighted MR imaging sequences at baseline and 3-year clinical follow-up. Analysis was performed with NeuroQuant and Neuroreader. Receiver operating characteristic curves assessing the prognostic efficacy of each software package were generated by using a univariable approach using individual regional brain volumes and 2 multivariable approaches (multiple regression and random forest), combining multiple volumes. On univariable analysis of 11 NeuroQuant and 11 Neuroreader regional volumes, hippocampal volume had the highest area under the curve for both software packages (0.69, NeuroQuant; 0.68, Neuroreader) and was not significantly different ( P > .05) between packages. Multivariable analysis did not increase the area under the curve for either package (0.63, logistic regression; 0.60, random forest NeuroQuant; 0.65, logistic regression; 0.62, random forest Neuroreader). Of the multiple regional volume measures available in FDA-cleared brain volumetric software packages, hippocampal volume remains the best single predictor of conversion of mild cognitive impairment to Alzheimer disease at 3-year follow-up. Combining volumetrics did not add additional prognostic efficacy. Therefore, future prognostic studies in mild cognitive impairment, combining such tools with demographic and other biomarker measures, are justified in using hippocampal volume as

    Adults with HIV infection are living into old age. It is critical we investigate positive constructs such as resilience and mastery to determine factors associated with psychological well-being. We examine HIV-related factors, adverse conditions, and psychosocial characteristics that are associated with resilience (the ability to bounce back) and mastery (sense of self-efficacy). We analyzed 2014 data from the longitudinal study Aging with Pride: National Health, Aging, and Sexuality/Gender Study (NHAS), focusing on a subsample of 335 gay and bisexual older men. Multivariate linear regression was used to identify factors that contributed or detracted from resilience and mastery in the sample recruited from 17 sites from across the United States. Resilience and mastery were independently associated with psychological health-related quality of life. In multivariate analysis, adjusting for demographic characteristics, previous diagnosis of depression was negatively associated with resilience. Time since HIV diagnosis was positively associated with mastery whereas victimization was negatively associated with mastery. Social support and community engagement were positively associated with both resilience and mastery. Individual and structural-environmental characteristics contributed to resilience and mastery. These findings can be used to develop interventions incorporating an increased understanding of factors that are associated with both resilience and mastery. © The Author 2017.

    Purpose: Although the link between depression and lower levels of mastery is well established, limited information exists on ethnic and gender differences in the association between the two. The current study investigated ethnic, gender, and ethnic by gender differences in the link between major depressive disorder (MDD) and low mastery in the United States. Methods: We used data from the National Survey of American Life-Adolescent supplement (NSAL-A), 2003–2004. In total, 1170 Black adolescents entered the study. This number was composed of 810 African-American and 360 Caribbean Black youth (age 13 to 17). Demographic factors, socioeconomic status (family income), mastery (sense of control over life), and MDD (Composite International Diagnostic Interview, CIDI) were measured. Logistic regressions were used to test the association between mastery and MDD in the pooled sample, as well as based on ethnicity and gender. Results: In the pooled sample, a higher sense of mastery was associated with a lower risk of MDD. This association, however, was significant for African Americans but not Caribbean Blacks. Similarly, among African American males and females, higher mastery was associated with lower risk of MDD. Such association could not be found for Caribbean Black males or females. Conclusion: Findings indicate ethnic rather than gender differences in the association between depression and mastery among Black youth. Further research is needed to understand how cultural values and life experiences may alter the link between depression and mastery among ethnically diverse Black youth. PMID:28498355

    Full Text Available Two motivational theories – the Achievement Goal Theory and Self-Determination Theory – have recently been combined to explain students’ motivation, making it possible to study the “what” and the “why” of learners’ achievement strivings. The present study built on this approach by (a investigating whether the distinction between autonomous or volitional and controlling or pressuring reasons can be meaningfully applied to the adoption of mastery-avoidance goals, (b investigating the concurrent and prospective relations between mastery-avoidance goals and their underlying reasons and learning strategies when mastery-approach goals and their underlying reasons were also considered, and by (c incorporating psychological need experiences as an explanatory variable in the relation between achievement motives (i.e., the motive to succeed and motive to avoid failure and both mastery goals and their underlying reasons. In two Turkish university students samples ('N' = 226, 'Mage '= 22.36; 'N' = 331, 'Mage '= 19.5, autonomous and controlling reasons appeared applicable to mastery-avoidance goals and regression and path analysis further showed that mastery-avoidance goals and their underlying autonomous reasons fail to predicted learning strategies over and above the pursuit of mastery-approach goals and their underlying reasons. Finally, need experiences were established as mediators between achievement motives and both mastery goals and their underlying reasons.

    Dark matter in galaxies, its abundance, and its distribution remain a subject of long-standing discussion, especially in view of the fact that neither dark matter particles nor dark matter bodies have yet been found. Experts' opinions range from a very large number of completely dark galaxies exist to nonbaryonic dark matter does not exist at all in any significant amounts. We discuss astronomical evidence for the existence of dark matter and its connection with visible matter and examine att...

    2015-06-01

    This paper is part of a series of studies to improve the efficacy of online physics homework activities by integrating narrated animated solutions with mastery inspired exercises. In a clinical study using first- and second-year university students, the mastery group attempted question sets in four levels, with animated solutions between each attempt, until mastery was achieved on each level. This combined elements of formative assessment, the worked example effect, and mastery learning. The homework group attempted questions with immediate feedback and unlimited tries. The two groups took a similar amount of time to complete the activity. The mastery group significantly outperformed the homework group on a free response post-test that required students to show their work in solving near and far transfer problems.

  4. The interactive roles of mastery climate and performance climate in predicting intrinsic motivation.

    2017-02-01

    This study examined the interplay between perceived mastery and performance climates in predicting increased intrinsic motivation. The results of a two-wave longitudinal study comprising of 141 individuals from three military academies revealed a positive relationship between a perceived mastery climate and increased intrinsic motivation only for individuals who perceived a low performance climate. This finding suggests a positive relationship between a perceived mastery climate and increased intrinsic motivation only when combined with low perceptions of a performance climate. Hence, introducing a performance climate in addition to a mastery climate can be an undermining motivational strategy, as it attenuates the positive relationship between a mastery climate and increased intrinsic motivation. Implications for future research and practice are discussed. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The purpose of this study was to test a portion of the uncertainty in illness model to determine whether mastery would be strengthened or weakened under conditions of uncertainty, and to test the ability of mastery and coping to function as mediators in the model. Mastery was proposed to mediate the relationship between uncertainty and the appraisal of danger and opportunity. Coping was proposed to mediate the relationships between danger or opportunity and emotional distress. Data were collected on a sample of 131 women receiving treatment for gynecological cancer. Findings support mastery as weakened under conditions of uncertainty and functioning as a situationally specific personality factor. Mastery was a significant mediator of the relationship between uncertainty and the appraisal of danger and opportunity; although the mediation effect for the relationship between uncertainty and danger was stronger. While two coping strategies were found to function as significant mediators between danger or opportunity and emotional distress, the mediation effect was very small.

V-I-I involved: video-recording trainee-taught lessons; and two interviews – with a pupil group to probe learning occurring in the lesson and with the trainee.Eighty UK-based trainees taking a one-year postgraduate teacher education course completed the questionnaire probing perceptions about university- and school-based training sessions designed to develop science subject matter knowledge (SMK and pedagogical content knowledge (PCK. Six trainees participated in V-I-I.Most trainees saw all sessions as SMK-based, regardless of teacher educators’ intended purposes. Lesson videos revealed ”describing” activities, task completion and good behaviour as main focii. Explanation of key science ideas and use of materials and /ideas from training sessions were largely absent. Trainee interviews revealed contrasts: most perceived a lesson as “successful” when children completed tasks quietly. Other trainees realised their understanding impacted on pupils’ learning science concepts. Pupil interviews showed positive attitudes towards science and learning difficult ideas, but little specific learning of topics taught.

    Plaud (J Clin Psychol 57, 1089-1102, 1109-1111, 1119-1120) and Ilardi and Feldman (J Clin Psychol 57, 1067-1088, 1103-1107, 1113-1117, 1121-1124) argue for two very different approaches to clinical science and practice (i.e., behavior analysis and cognitive neuroscience, respectively). We comment on the assets and liabilities of both perspectives as presented and attempt to achieve some semblance of balance between the three protagonists embroiled in this current debate. The vision of clinical science we articulate is more ecumenical and evolutionary, rather than paradigmatic and revolutionary. As we see it, the problem clinical psychology faces is much larger than the authors let on; namely, how best to make clinical science meaningful and relevant to practitioners, consumers, the general public, and the behavioral health-care community. Clinical psychology's immediate internal problem is not pluralism with regard to subject matter, worldview, methodology, or school of thought, but pluralism in clinical psychologists' adherence to a scientific epistemology as the only legitimate form of clinical psychology. On this latter point, we still have a very long way to go. Copyright 2001 John Wiley & Sons, Inc.

    Simulation-based mastery learning (SBML), like all education interventions, has learning theory foundations. Recognition and comprehension of SBML learning theory foundations are essential for thoughtful education program development, research, and scholarship. We begin with a description of SBML followed by a section on the importance of learning theory foundations to shape and direct SBML education and research. We then discuss three principal learning theory conceptual frameworks that are associated with SBML-behavioral, constructivist, social cognitive-and their contributions to SBML thought and practice. We then discuss how the three learning theory frameworks converge in the course of planning, conducting, and evaluating SBML education programs in the health professions. Convergence of these learning theory frameworks is illustrated by a description of an SBML education and research program in advanced cardiac life support. We conclude with a brief coda.

    Full Text Available Vocabulary is basic part of language when we learn english. Nowadays, introducing english vocabulary can be started in the kindergarten school. In early age, the young learners are easy to accept the language that has been given by teacher. Therefore, young learner in early age (approximately 3-4 years old should get stimulation and learn English vocabulary in order to get preparation to study in higher level. This research was conducted to increase the young learners’ vocabulary mastery in b class of tungga dewi day-care. The classroom action research was implemented in this research. The teaching technique using songs were implemented through teaching and learning activities in two cycles of classroom action research. Each cycle of classroom action research was planning, acting, observing and reflecting. In this research, instruments to gather the data were field notes and observation checklists. Field notes and observation checklists were applied to take the data during the teaching learning process. The data would be analysed in order to solve the problems. Songs were applied in the activities of the first cycle of classrooms action research. The result of the first cycle was not quiet successful because the average of post –test score in cycle one was 37,8. Therefore, the teacher-researcher conducted the second cycle. The second cycle was conducted based on the result of the first cycle. Songs were combined the body movement in second cycle of the classroom action research. The result of the second cycle was successful because the average of post-test score was 77,78. As a conclusion, it can be concluded that the implementation of english songs could help to increase the young learner’s vocabulary mastery.

    2017-08-30

    The purposes of this exploratory project were: (1) to evaluate the impact of power mobility training with a child who has multiple, severe impairments and (2) to determine if the child's spectrum of electroencephalography (EEG) activity changed during power mobility training. A single-subject A-B-A-B research design was conducted with a four-week duration for each phase. Two target behaviours were explored: (1) mastery motivation assessed via the dimensions of mastery questionnaire (DMQ) and (2) EEG data collected under various conditions. Power mobility skills were also assessed. The participant was a three-year, two-month-old girl with spastic quadriplegic cerebral palsy, gross motor function classification system level V. Each target behaviour was measured weekly. During intervention phases, power mobility training was provided. Improvements were noted in subscale scores of the DMQ. Short-term and long-term EEG changes were also noted. Improvements were noted in power mobility skills. The participant in this exploratory project demonstrated improvements in power mobility skill and function. EEG data collection procedures and variability in an individual's EEG activity make it difficult to determine if the participant's spectrum of EEG activity actually changed in response to power mobility training. Additional studies are needed to investigate the impact of power mobility training on the spectrum of EEG activity in children who have multiple, severe impairments. Implications for Rehabilitation Power mobility training appeared to be beneficial for a child with multiple, severe impairments though the child may never become an independent, community-based power wheelchair user. Electroencephalography may be a valuable addition to the study of power mobility use in children with multiple, severe impairments. Power mobility training appeared to impact mastery motivation (the internal drive to solve complex problems and master new skills) in a child who has multiple

    The laparoscopic totally extraperitoneal (TEP) inguinal herniorrhaphy requires 250 repairs to master. Simulation training could potentially accelerate this process. We describe the development, evaluation and implementation of a TEP mastery learning curriculum. We developed a 2-stage curriculum comprising online knowledge modules and skills practice on a simulator (the Guildford-MATTU TEP trainer; Limbs & Things, Ltd, Bristol, UK). Learners demonstrated mastery at each stage before advancing. The knowledge endpoint was a multiple-choice test. The skills endpoint was procedure time, as established by timing 5 experienced staff surgeons. Participants were proctored individually, receiving personalized feedback after each attempt until mastery time was achieved. The times to perform a simulated repair, number of attempts, and training time to reach mastery were compared between groups. The mastery time was established at 2 minutes. Nine medical students, 36 general surgery residents (PGY 1-5), and 3 surgery fellows participated as learners. All learners achieved the knowledge and skills mastery endpoints. For the skill endpoint, participants required a median of 69 minutes (range, 13-193 minutes) and 16 simulated repairs (range, 7-27 repairs). The mean number of attempts and total training time to reach mastery varied by group (p TEP repair under artificial conditions with a performance similar to that of an expert, and are ready to move to the next phase of training in the operating room.

    Full Text Available The article is devoted to scientific analysis of the phenomenon of pedagogical mastery. Research findings on pedagogical mastery, pedagogical creativity, pedagogical technologies have been studied in the light of historical and pedagogical paradigm. In addition, various scientific approaches and views of scholars on the essence of pedagogical mastery have been considered and the ambiguity of their scientific interpretations has been justified. The scientific category of pedagogical mastery is regarded as a social, cultural and historical phenomenon, caused by the challenges of society in line with the relevant social priorities and directions according to the goals and objectives of a particular historical period. Subsequently, complexity and multidimensionality of the notion of pedagogical mastery and presence of various scientific approaches (technological, creative, personality- and activitybased to interpreting the scientific category have been proved. Based on the current sociocultural situation, the relevance of researches on pedagogical mastery as a scientific category has been proved and its role in training future teachers, which can be considered as a certain teaching strategy and factor in forming their readiness for innovative activity has been defined. It has been found out that diversity and interdisciplinarity of pedagogical mastery in the system of scientific knowledge promote methodological strategies for its research, the need for their systematization and complex implementation.

    To test the moderating role of the extent of fast-food restaurants in one's immediate environment in the association between mastery and metabolic risk. Higher sense of mastery (perceived control over one's circumstances) has been associated with better metabolic outcomes. Mastery may be instrumental in resisting unhealthful environmental food cues when these become ubiquitous, resulting in a greater health impact of mastery. Blood samples were obtained from 344 individuals (50% men), aged 18 to 57 years (mean, 34.9 years), sampled from seven census tracts representing the spectrum of census tract-level socioeconomic status and language (French/English) in Montreal. Risk factors based on standards for high-density lipoprotein and total cholesterol, waist circumference, body mass index, triglycerides, and glycated hemoglobin were summed to obtain a cumulative metabolic risk score. Mastery was self-reported, using a validated scale. The proportion of restaurants classified as fast-food within 500 m of participants' residences was determined, using a geographic information system. Main and interactive effects were tested with Poisson regression, accounting for clustering of observations and participants' age, gender, education, and income. Mastery interacted with fast-food exposure in relation to metabolic risk (p = .03). Higher mastery was significantly associated with lower metabolic risk for participants surrounded by a high proportion of fast food (relative risk, 0.80; 95% confidence interval, 0.76-0.84; p fast-food restaurants (relative risk, 0.94; 95% confidence interval, 0.82-1.08; p = .37). A positive relationship between mastery and lower metabolic risk was most apparent in environments with higher fast-food exposure.

    This study investigated associations between individual and work-related factors and perceived mastery of work among offshore shift workers. 2,406 employees of a Norwegian petroleum company were invited to participate. A web-based survey was used and 1336 completed questionnaires were returned (56%). Mastery of work was assessed using QPS Nordic Mastery Scale and the results were compared with a sample from the QPS Nordic study. Individual factors adjusted for were age, gender, marital status and personality. The following work-related factors were included: demands, control, support, night work and shift work home interference. Female offshore shift workers reported higher levels of perceived mastery of work compared with women in the comparison sample. The following variables were independently associated with perceived mastery of work: female gender (β=0.10, p=0.008), decisional demands (β=0.13, ppetroleum offshore workers reported somewhat higher levels of mastery of work than their male colleagues, however, this may be due to different work positions. Work-related factors accounted for about half of the explained variance and decisional demands, control and support remained statistically significant after controlling for personality.

This research uses a descriptive method. The data were taken using instruments CoRes as the primary data and semi-structured interviews as supporting data. The subjects were biology teacher in class X MIA from four schools in Bandung. Teachers raised CoRes was analyzed using a scoring rubric CoRes with coding 1-3 then categorized into a group of upper, middle, or lower. The results showed that the two teachers in the lower category. This results means that the control of teachers in defining the essential concept in the CoRes has not been detailed and specific. Meanwhile, two other teachers were in the middle category. This means that the ability of teachers to determine the essential concepts in the CoRes are still inadequate so that still needs to be improved.

  5. The Role of Teachers' Pedagogical and Subject-Matter Knowledge in Planning and Enacting Science-Inquiry Instruction, and in Assessing Students' Science-Inquiry Learning

    Birlean, Camelia

    This study explored the relation between pedagogical knowledge and subject-matter knowledge, in the context of inquiry-driven science instruction, and their relation to instructors' performance in the instructional process. This multiple case study focused on three distinct categories of teachers--Novice in Inquiry and in Science, Novice in Inquiry and Expert in Science, and Expert in Inquiry and in Science--and examined the commonalities and differences among them by exploring the cognitive processes these teachers used when planning and enacting an inquiry instructional situation, as well as when assessing students' learning resulting from this specific instructional event. Inquiry instruction varied across cases from largely structured to largely open. The Novice-Novice's science instruction, predominantly traditional in the approach, differed greatly from that of the Expert-Expert and of the Novice-Expert. The latter two emphasized--to various extents structured, guided, and open--inquiry strategy as part of their ongoing instruction. The open inquiry was an approach embraced solely by the Expert-Expert teacher throughout the Advanced Science Research instruction, emphasizing the creative aspect of problem generation. Edward teacher also distinguished himself from the other two participants in his view of planning and terminology used to describe it, both of which emphasized the dynamic and flexible feature of this instructional process. The Expert-Expert identified occasional planning, planning of specific skills and content critical to students' learning process during their independent inquiry. The observed teaching performance of the three participants partly reflected their planning; the alignment was least frequent for the Novice-Novice. The assessment of inquiry-based projects varied greatly across participants. Each teacher participant evaluated a set of three inquiry-based science projects that differed in their quality, and this variation increased

Methods: An intervention group of 82 children (35 boys and 47 girls and a control group of 83 children (42 boys and 41 girls were recruited from Years 4 and 5 (mean age ± SD = 8.3 ± 0.4 years of two schools in Central England. The intervention included a combination of circuits and dancing to music. Pre and post intervention tests were conducted. Tests included: subjective assessment of eight FMS; objective measurement of two FMS; four day pedometer step count recording; height and mass for Body Mass Index (BMI; and the completion of Harter et al.’s (1982 self-perception questionnaire. Results: Following a two (pre to post by two (intervention and control group mixed-model ANOVA it was highlighted that the intervention group improved mastery in all eight FMS, and increased both daily steps and physical self-perception. Conclusions: It can be concluded that focussing one Physical Education (PE lesson per week on the development of FMS has had a positive benefit on FMS, PA level and physical self-perception for the children in this study.

    How do you get to Carnegie Hall? Practice, sleep, practice. With enough practice - and sleep - we adopt new strategies that eventually become automatic, and subsequently require only the refinement of the existing skill to become an "expert". It is not known whether sleep is involved in the mastery and refinement of new skills that lead to expertise, nor is it known whether this may be primarily dependent on rapid eye movement (REM), non-REM stage 2 (NREM2) or slow wave sleep (SWS). Here, we employed behavioural and scalp-recorded electroencephalography (EEG) techniques to investigate the post-learning changes in the architecture (e.g., REM, NREM2 and SWS duration) and the electrophysiological features (e.g., rapid eye movements, sleep spindles and slow wave activity) that characterize these sleep states as individuals progress from night to night, from "Novice" to "Experts" on a cognitive procedural task (e.g., the Tower of Hanoi task). Here, we demonstrate that speed of movements improves over the course of training irrespective of whether sleep or wake intervenes training sessions, whereas accuracy improves gradually, but only significantly over a night of sleep immediately prior to mastery of the task. On the night that subjects are first exposed to the task, the density of fast spindles increased significantly during both NREM2 and SWS accompanied by increased NREM2 sigma power and SWS delta power, whereas, on the night that subjects become experts on the task, they show increased REM sleep duration and spindles became larger in terms of amplitude and duration during SWS. Re-exposure to the task one-week after it had already been mastered resulted in increased NREM sleep duration, and again, increased spindle density of fast spindles during SWS and NREM2 and increased NREM2 sigma power and SWS delta power. Importantly, increased spindle density was correlated with overnight improvement in speed and accuracy. Taken together, these results help to elucidate how

    Full Text Available Subjective cognitive impairment may be a very early at-risk period of the continuum of dementia. However, it is difficult to discriminate at-risk states from normal aging. Thus, detection of the early pathological changes in the subjective cognitive impairment period is needed. To elucidate these changes, we employed diffusion tensor imaging and volumetry analysis, and compared subjective cognitive impairment with normal, mild cognitive impairment and Alzheimer's disease. The subjects in this study were 39 Alzheimer's disease, 43 mild cognitive impairment, 28 subjective cognitive impairment and 41 normal controls. There were no statistically significant differences between the normal control and subjective cognitive impairment groups in all measures. Alzheimer's disease and mild cognitive impairment had the same extent of brain atrophy and diffusion changes. These results are consistent with the hypothetical model of the dynamic biomarkers of Alzheimer's disease.

    2011-01-01

    There have been dramatic changes in the specialty of family medicine and the American health care system in the more than 40 years since the formation of the specialty. As a result, there is urgent need for experimentation and innovation in residency training to better prepare family physicians. Waukesha Family Medicine Residency used a strategic planning process to identify four guiding concepts for a new model of residency education: intentional diversification; options for advanced training in a fourth year of residency; longitudinal, competency-based training; and strong fundamental background in family medicine skills. These concepts guided radical restructuring of the curriculum. The new Majors and Masteries curriculum begins with 19 months of training in core family medicine skills. Residents then elect to pursue a Major or Mastery in an area of interest. Majors are completed within 3 years, while Masteries are completed in 4 years and include advanced training (MPH, MBA, advanced obstetrics). Since implementation, residents have selected a broad range of Majors, three residents have elected advanced training in three different mastery areas, and resident recruitment has not been disrupted. The Majors and Masteries curriculum and the process used to implement it may benefit other residencies considering radical curriculum change.

  12. [Do mastery goals buffer self-esteem from the threat of failure?].

    Self-esteem is vulnerable when failure occurs in the domain where people base their self-worth (Crocker & Wolfe, 2001). We tested whether learning orientations can reduce the vulnerability of self-esteem associated with contingent self-worth and encourage persistence following failure. Our past research (Niiya, Crocker, & Bartmess, 2004) indicated that people who base their self-worth on academics maintain their self-esteem following failure when they are primed with an incremental theory of intelligence. Our present study extends these findings by (a) examining whether mastery goals (Elliot & Church, 1997) can also buffer self-esteem from failure, (b) using a different manipulation of success and failure, (c) using a different task, and (d) including a measure of persistence. We found that college students who based their self-esteem on academic competence reported lower self-esteem following failure than following success when they had low mastery goals, but the effect of success and failure was eliminated when students had high mastery goals. Moreover, high mastery students showed greater persistence following failure than low mastery students. The study provided converging evidence that learning orientations buffer self-esteem from failure.

    2016-10-01

    Full Text Available It has been suggested that guidance, encouragement and opportunity are crucial factors for children’s motor development. They are especially important to promote the mastery of fundamental movement skills. The present study investigated the association between two elements related to those factors – proposed curriculum of physical education and the most popular sport in a given country – and the incidence of mastery in the FMS in children from 4 to 10 years of age. In order to carry out a cross-cultural comparison, three studies from different countries (Portugal, China and USA that used TGMD-II were selected. The results indicated association between proposed curriculum and the number of children mastering FMS. This association increases in older age groups of children from USA, the most structured curriculum related to FMS, presenting the highest average percentage of mastery.  Additionally, we did not find association of the most popular sports in a given country with the mastery of the related skill. These results are interpreted as evidence for the importance of guidance on the mastery of FMS.

    Low episodic memory performance characterizes elderly subjects at increased risk for Alzheimer's disease (AD) and may reflect neuronal dysfunction within the posterior cingulate cortex and precuneus (PCP) region. To investigate a potential association between cerebral neurometabolism and low episodic memory in the absence of cognitive impairment, tissue-specific magnetic resonance spectroscopic imaging at ultrahigh field strength of 7 Tesla was used to investigate the PCP region in a healthy elderly study population (n = 30, age 70 ± 5.7 years, Mini-Mental State Examination 29.4 ± 4.1). The Verbal Learning and Memory Test (VLMT) was administered as part of a neuropsychological battery for assessment of episodic memory performance. Significant differences between PCP gray and white matter could be observed for glutamate-glutamine (p = 0.001), choline (p = 0.01), and myo-inositol (p = 0.02). Low Verbal Learning and Memory Test performance was associated with high N-acetylaspartate in PCP gray matter (p = 0.01) but not in PCP white matter. Our data suggest that subtle decreases in episodic memory performance in the elderly may be associated with increased levels of N-acetylaspartate as a reflection of increased mitochondrial energy capacity in PCP gray matter.

    Traditionally, psychomotor skills training for nursing students involves didactic instruction followed by procedural review and practice with a task trainer, manikin, or classmates. This article describes a novel method of teaching psychomotor skills to associate degree and baccalaureate nursing students, Cooperative Learning Simulation Skills Training (CLSST), in the context of nasogastric tube insertion using a deliberate practice-to-mastery learning model. Student dyads served as operator and student learner. Automatic scoring was recorded in the debriefing log. Student pairs alternated roles until they achieved mastery, after which they were assessed individually. Median checklist scores of 100% were achieved by students in both programs after one practice session and through evaluation. Students and faculty provided positive feedback regarding this educational innovation. CLSST in a deliberate practice-to-mastery learning paradigm offers a novel way to teach psychomotor skills in nursing curricula and decreases the instructor-to-student ratio.

    2002-03-01

    Achievement goals and perceived motivational climate are two important constructs in achievement goal theory, and they play critical roles in student motivation and behavior Traditionally, these two constructs have been examined separately. The present study examined relationships between the two constructs and students' self-reported mastery behaviors as well as age-related differences. Three hundred eight students in 4th, 8th, and 11th grades completed questionnaires assessing their achievement goals, perceived motivational climate, and perceptions of their mastery behaviors. Results indicated that achievement goals and perceived motivational climate were related to students' self-reported mastery behaviors. However, the relations varied depending on the students' ages. The older students, compared to the younger ones, appeared to be inclined more toward ego orientation and the ego-involved climate. A multiple achievement goals perspective is recommended for future research on relationships among achievement goals, perceived motivational climate and achievement-related cognitions, and behaviors in physical education.

    Fearon-Lynch, Jennifer A; Stover, Caitlin M

    2015-01-01

    Diabetes mellitus is the seventh leading cause of death in America and affects 382 million people worldwide. Individuals with diabetes must manage the complexity of the disease, its treatment, and complications to avert deleterious consequences associated with the illness. However, not all patients with diabetes successfully gain mastery to positively impact self-management. A new middle-range theory is proposed that merges 2 extant theories, theory of mastery and organismic integration theory, to better understand this human response. The theories' philosophical, theoretical, and conceptual perspectives were examined and relational properties synthesized to provide a conceptual representation of the phenomenon of interest.

    This paper reports the use of excitation-emission matrix fluorescence spectroscopy (EEMS), parallel factor statistical analysis (PARAFAC), and oxidation-reduction experiments to examine the effect of redox conditions on PARAFAC model results for aqueous samples rich in natural organic matter. Fifty-four aqueous samples from 11 different geographic locations and two plant extracts were analyzed untreated and after chemical treatments or irradiation were used in attempts to change the redox status of the natural organic matter. The EEMS spectra were generated and modeled using a PARAFAC package developed by Cory and McKnight (2005). The PARAFAC model output was examined for consistency with previously reported relations and with changes expected to occur upon experimental oxidation and reduction of aqueous samples. Results indicate the implied fraction of total sample fluorescence attributed to quinone-like moieties was consistent (0.64 to 0.78) and greater than that observed by Cory and McKnight (2005). The fraction of the quinone-like moieties that was reduced (the reducing index, RI) showed relatively little variation (0.46 to 0.71) despite attempts to alter the redox status of the natural organic matter. The RI changed little after reducing samples using zinc metal, oxidizing at high pH with air, or irradiating with a Xenon lamp. Our results, however, are consistent with the correlations between the fluorescence indices (FI) of samples and the ratio of PARAFAC fitting parameters suggested by Cory and McKnight (2005), though we used samples with a much narrower range of FI values.

    2017-06-01

    To examine the probability of a high sense of mastery in a population-representative sample of working-age people and to study the differences in mastery between Finnish-speaking and Swedish-speaking Finns in particular. The data originates from the Western Finland Mental Health Surveys (2008-2014). Associations between sense of mastery and language groups were analyzed with logistic regressions. Swedish-speaking Finns have a higher sense of mastery and the association is mediated by social support. Moreover, a difference in a high sense of mastery is found between Swedish- and Finnish-speaking married women that are outside the labor market. Our findings imply that Finnish-speaking women that are outside the labor market, e.g. on maternity leave or taking care of the household, should be recognized in health and social care services as a group that can benefit from additional support.

    OBJECTIVES. Deficits in metacognition, or the ability to think about thinking, are common in schizophrenia and associated with functional impairment. Unknown are what elements of function are affected by what aspects of metacognition. DESIGN. This study explored whether participants with differing capacities for Mastery, a domain of metacognition that reflects the ability to use knowledge about mental states to respond to psychological challenges, had difficulties in different elements of daily function. METHODS. Participants were 98 adults with schizophrenia or schizoaffective disorder in a non-acute phase, classified into three groups on the basis of ratings of their capacity for metacognitive Mastery using the Metacognitive Assessment Scale: low Mastery (those unable to plausibly represent psychological challenges), Intermediate Mastery (those able to plausibly represent psychological problems but cope primarily through passive measures or avoidance), and high Mastery (those able to cope with plausible problems through cognitive means). Participants completed assessments of coping preference, insight, self-esteem, and anxiety. RESULTS. Multivariate Analysis of Variance (MANOVA) and Analysis of Variance (ANOVA) revealed that the high-Mastery group had a greater preference for coping with stressors by thinking and talking about them, and greater insight than all other groups, and higher levels of feeling accepted by peers than the intermediate-Mastery group. The intermediate-Mastery group reported higher levels of resignation when facing stressors and more social phobia than the other two groups. These findings of Mastery group differences in self-esteem and anxiety persisted when neurocognition was controlled for in an Analysis of Covariance (ANCOVA). CONCLUSIONS. Mastery appears linked to coping preference, insight, self-esteem, and anxiety in a generally non-linear manner. ©2011 The British Psychological Society.

    2014-10-28

    The present study aimed to clarify the nature and dimensions of achievement goals and to examine structural differences in students' goals across school levels. Participants were 134 students from 5th and 6th grades, and 423 students from 7th to 9th grades. A variety of achievement goals were assessed, including mastery goals and several performance-related goals representing three main dimensions: competition, self-presentation, and valence. Two alternative models were tested, using confirmatory factor analysis. For middle-school students a three factor model with presentation, competition, and simple evaluation/mastery goals, was found χ²(132, N = 134) = 160.9, p competition factor, and a simple evaluation/mastery factor, best fitted the data χ²(114, N = 423) = 269.8638 p competition goals, and (b) simple evaluation goals, which encompass neither self-presentation nor competition, and are closely linked to mastery goals. Moreover, significant differences were found in the relative importance attached by students to the different types of goals (p < .001 for all comparisons), both at middle-school F(2, 266) = 220.98; p < .001; η2 = .624) and at junior-high school F(2, 820) = 464.4; p < .001; η2 = .531.

    2017-02-01

    Full Text Available Vocabulary is an essential component in learning English. It influences four English skills; they are listening, speaking, reading, and writing, for getting a good result in English. In teaching learning process, the teacher often implements the less interesting method, technique, or even media of vocabulary mastery in teaching and learning process which make the students to be bored, inactive, an uniterested in memorizing English vocabulary. Some media can be interested as the solutions in vocabulary mastery, they are Snake Ladders media and Scrabble media. The investigation was undergone by quantitative research. The researcher applied experimental research. This research underwent pre-test post-test control group design. To analyze data, t-test formula is used to measure the result of collected data. From the t-test measurement, it showed that t-test is 3.15 and t-table is 2.66. It means that t-hit > t-table. Based on the collected data, there is different result of using Snake Ladders from Scrabble media toward students’ vocabulary mastery. It was found that the students who are taught by using Snake Ladders resulted significant outcome than those are instructed by Scrabble media. It means that Snake Ladders is effective to improve the students’ vocabulary mastery.

    Dissemination of a medical education innovation, such as mastery learning, from a setting where it has been used successfully to a new and different medical education environment is not easy. This article describes the uneven yet successful dissemination of a simulation-based mastery learning (SBML) curriculum on central venous catheter (CVC) insertion for internal medicine and emergency medicine residents across medical education settings. The dissemination program was grounded in implementation science principles. The article begins by describing implementation science which addresses the mechanisms of medical education and health care delivery. The authors then present a mastery learning case study in two phases: (1) the development, implementation, and evaluation of the SBML CVC curriculum at a tertiary care academic medical center; and (2) the dissemination of the SBML CVC curriculum to an academic community hospital setting. Contextual information about the drivers and barriers that affected the SBML CVC curriculum dissemination is presented. This work demonstrates that dissemination of mastery learning curricula, like all other medical education innovations, will fail without active educational leadership, personal contacts, dedication, hard work, rigorous measurement, and attention to implementation science principles. The article concludes by presenting a set of lessons learned about disseminating an SBML CVC curriculum across different medical education settings.

    Li, Chiung-Huang

    2010-06-01

    The major purpose of this study was to test the hypothesized paths from dualistic passions through achievement goals to subjective vitality and performance in sports. 645 high school athletes participated. The proposed structural equation model, with relationships between dualistic passions and subjective vitality and sports performance mediated by achievement goals, fit the data well, especially for mastery-approach and performance-approach goals. Harmonious and obsessive passions may lead athletes to high performance via the adoption of mastery-approach goals. However, these passions seem to have two paths influencing personal functioning: direct effects make players feel energetic, and indirect effects on subjective vitality through adoption of mastery-approach and performance-approach goals.

    Diffusion tensor imaging (DTI) characterizes white matter (WM) microstructure. In many brain regions, however, the assumption that the diffusion probability distribution is Gaussian may be invalid, even at low b values. Recently, diffusion kurtosis imaging (DKI) was suggested to more accurately estimate this distribution. We explored the added value of DKI in studying the relation between WM microstructure and upper limb coordination in healthy controls (N = 24). Performance on a complex bimanual tracking task was studied with respect to the conventional DTI measures (DKI or DTI derived) and kurtosis metrics of WM tracts/regions carrying efferent (motor) output from the brain, corpus callosum (CC) substructures and whole brain WM. For both estimation models, motor performance was associated with fractional anisotropy (FA) of the CC-genu, CC-body, the anterior limb of the internal capsule, and whole brain WM (r s range 0.42-0.63). Although DKI revealed higher mean, radial and axial diffusivity and lower FA than DTI (p motor performance was associated with increased mean and radial kurtosis and kurtosis anisotropy (r s range 0.43-0.55). In conclusion, DKI provided additional information, but did not show increased sensitivity to detect relations between WM microstructure and bimanual performance in healthy controls.

    2012-09-01

    The purpose of this study was to evaluate the effectiveness of online mastery quizzes in enhancing dental students' learning and preparedness for anatomy examinations. First-year dental students taking an integrated anatomy course at The Ohio State University were administered online mastery quizzes, made available for five days before each examination. The mastery quizzes were comprised of ten multiple-choice questions representative of the upcoming examination in content and difficulty. The students were allowed to access this resource as many times as they desired during the five-day window before each examination; the highest score for each student was added to his or her final course grade. The results indicate that almost all the students took advantage of this resource to reinforce content, clarify concepts, and prepare for the examinations. Statistical analyses of the students' exam performance showed that the mastery quizzes neither improved nor reduced their exam scores, but multiple regression analyses showed that the initial mastery quiz scores had a predictive value for their examination performance, suggesting a potential for mastery quizzes as an intervention tool for such a course. Online mastery quizzes, when used effectively, may be an effective resource to further engage dental and other students in educational endeavors and examination preparation and as a predictor of success.

    Full Text Available The study aimed, firstly, to assess a group of Indonesian adult EFL students’ mastery of tenses and aspects as part of their mastery of English grammar and, secondly, to identify if their experience of going through the instructional processes, their perceptions of and habits in studying English grammar shaped their mastery of tenses and aspects. The data were collected through a grammar test and a semi-structured interview. As the study was conducted, the students were sitting in the fourth (last year of their study. Despite having such long instructional experience, however, the findings show that the mastery of tenses and aspects of majority of the students still fell into the “fail” category. Also, their having perception that studying English grammar is important apparently did not shape their mastery of tenses and aspects. What seemed influential as to shaping their mastery was much more related to their habits in studying, the modes of instruction they experienced, and the type of language samples they were exposed to, especially during the process of receiving grammar instruction in the classroom. Keywords: grammatical competence, mastery of tenses and aspects, English as a foreign language

    Competency-based education requires individualization of instruction. Mastery learning, an instructional approach requiring learners to achieve a defined proficiency before proceeding to the next instructional objective, offers one approach to individualization. The authors sought to summarize the quantitative outcomes of mastery learning simulation-based medical education (SBME) in comparison with no intervention and nonmastery instruction, and to determine what features of mastery SBME make it effective. The authors searched MEDLINE, EMBASE, CINAHL, ERIC, PsycINFO, Scopus, key journals, and previous review bibliographies through May 2011. They included original research in any language evaluating mastery SBME, in comparison with any intervention or no intervention, for practicing and student physicians, nurses, and other health professionals. Working in duplicate, they abstracted information on trainees, instructional design (interactivity, feedback, repetitions, and learning time), study design, and outcomes. They identified 82 studies evaluating mastery SBME. In comparison with no intervention, mastery SBME was associated with large effects on skills (41 studies; effect size [ES] 1.29 [95% confidence interval, 1.08-1.50]) and moderate effects on patient outcomes (11 studies; ES 0.73 [95% CI, 0.36-1.10]). In comparison with nonmastery SBME instruction, mastery learning was associated with large benefit in skills (3 studies; effect size 1.17 [95% CI, 0.29-2.05]) but required more time. Pretraining and additional practice improved outcomes but, again, took longer. Studies exploring enhanced feedback and self-regulated learning in the mastery model showed mixed results. Limited evidence suggests that mastery learning SBME is superior to nonmastery instruction but takes more time.

    Although intrinsic motivation has been linked repeatedly to performance and outcomes, the causal relationship between the two has remained unclear. To explain the link, this study considered the focusing influence of mastery goals. Using a three-wave panel study and hypotheses drawn from self-determination theory and achievement goal theory, the current study sought to clarify the relationships between intrinsic motivation, mastery goal orientation, and performance. Specifically, the current study hypothesized and found that mastery goals mediated (explained) the relationship between intrinsic motivation and performance.

    Full Text Available A student with intellectual disability who has low level of intelligence and adaptive skills, a weak and abstract thinking needs a special approach of learning. The concept of weight measuring on student with intellectual disability is an abstract concept. Mastering concept of weight happens on student with intellectual disability is that if there is an object which seems to be larger or more is definitely heavier. This concept implies on the learning approaches used by educators in instilling the concept of weight measurement correctly. Therefore, before students start to study about the concept of actual weight need to be bridged with the real concept of scales and weighing process to ascertain the nature of the weight of an object. The goal of this research was to describe the effect of the scales mediausage toward mastery of the weight measuring concept on student with intellectual disability in the class VII. The research design used in this study was Single Subject Research (SSR with models A-B-A and using the unit of measuring scores. The results showed that there was the effect of the media on the mastery of weight scales concept. It was stated in the calculation of the overlap percentage between phases of baseline-1 to 0% of the intervention phase. This calculation stated that interventions have an impact on increasing the target behavior because the overlap percentages were below 90%.   Peserta didik tunagrahita adalah anak yang memiliki keterbatasan taraf kecerdasan dan keterampilan adaptif.

    Infurna, Frank J; Mayer, Axel

    2015-06-01

    Perceived control and health are closely interrelated in adulthood and old age. However, less is known regarding the differential implications of 2 facets of perceived control, constraints and mastery, for mental and physical health. Furthermore, a limitation of previous research testing the pathways linking perceived control to mental and physical health is that mediation was tested with cross-sectional designs and not in a longitudinal mediation design that accounts for temporal ordering and prior confounds. Using data from the Health and Retirement Study (HRS; n = 7,612, M age = 68, SD = 10.66; 59% women) we examined the effect of constraints and mastery on 4-year changes in mental and physical health and whether physical activity mediated such effects in a longitudinal mediation design. Using confirmatory factor analysis, we modeled the 2-factor structure of perceived control that consisted of constraints and mastery. In our longitudinal mediation model, where we accounted for possible confounders (e.g., age, gender, education, neuroticism, conscientiousness, memory, and health conditions), constraints showed a stronger total effect on mental and physical health, than mastery, such that more constraints were associated with 4-year declines in mental and physical health. Physical activity did not mediate the effect of constraints and mastery on mental and physical health (indirect effect). To demonstrate the importance of a longitudinal mediation model that accounts for confounders, we also estimated the mediated effect using 2 models commonly used in the literature: cross-sectional mediation model and longitudinal mediation model without accounting for confounders. These mediation models indicated a spurious indirect effect that cannot be causally interpreted. Our results showcase that constraints and mastery have differential implications for mental and physical health, as well as how a longitudinal mediation design can illustrate (or not) pathways in

    2011-07-01

    Background: Ambient air pollution is associated with adverse health effects, but the sources and components, which cause these effects is still incompletely understood. The aim of this thesis was to investigate the pulmonary effects of a variety of common air pollutants, including diesel exhaust, biomass smoke, and road tunnel and subway station environments. Healthy non-smoking volunteers were exposed in random order to the specific air pollutants and air/control, during intermittent exercise, followed by bronchoscopy. Methods and results: In study I, exposures were performed with diesel exhaust (DE) generated at transient engine load and air for 1 hour with bronchoscopy at 6 hours post-exposure. Immunohistochemical analyses of bronchial mucosal biopsies showed that DE exposure significantly increased the endothelial adhesion molecule expression of p-selectin and VCAM-1, together with increased bronchoalveolar lavage (BAL) eosinophils. In study II, the subjects were exposed for 1 hour to DE generated during idling with bronchoscopy at 6 hours. The bronchial mucosal biopsies showed significant increases in neutrophils, mast cells and lymphocytes together with bronchial wash neutrophils. Additionally, DE exposure significantly increased the nuclear translocation of the aryl hydrocarbon receptor (AhR) and phosphorylated c-jun in the bronchial epithelium. In contrast, the phase II enzyme NAD(P)H-quinone oxidoreductase 1 (NQO1) decreased after DE. In study III, the 2-hour exposures took place in a road tunnel with bronchoscopy 14 hours later. The road tunnel exposure significantly increased the total numbers of lymphocytes and alveolar macrophages in BAL, whereas NK cell and CD56+/T cell numbers significantly decreased. Additionally, the nuclear expression of phosphorylated c-jun in the bronchial epithelium was significantly increased after road tunnel exposure. In study IV, the subjects were exposed to metal-rich particulate aerosol for 2 hours at a subway station

  13. Do CS-US pairings actually matter? A within-subject comparison of instructed fear conditioning with and without actual CS-US pairings.

    Directory of Open Access Journals (Sweden)

    An K Raes

    Full Text Available Previous research showed that instructions about CS-US pairings can lead to fear of the CS even when the pairings are never presented. In the present study, we examined whether the experience of CS-US pairings adds to the effect of instructions by comparing instructed conditioning with and without actual CS-US pairings in a within-subject design. Thirty-two participants saw three fractals as CSs (CS(+1, CS(+2, CS(- and received electric shocks as USs. Before the start of a so-called training phase, participants were instructed that both CS(+1 and CS(+2 would be followed by the US, but only CS(+1 was actually paired with the US. The absence of the US after CS(+2 was explained in such a way that participants would not doubt the instructions about the CS(+2-US relation. After the training phase, a test phase was carried out. In this phase, participants expected the US after both CS(+s but none of the CS(+s was actually paired with the US. During test, self-reported fear was initially higher for CS(+1 than for CS(+2, which indicates that the experience of actual CS-US pairings adds to instructions about these pairings. On the other hand, the CS(+s elicited similar skin conductance responses and US expectancies. Theoretical and clinical implications are discussed.

    2011-06-01

    This study investigated the effectiveness of an Early Childhood Education science methods course that focused exclusively on providing various mastery (i.e., enactive, cognitive content, and cognitive pedagogical) and vicarious experiences (i.e., cognitive self-modeling, symbolic modeling, and simulated modeling) in increasing preservice elementary teachers' self-efficacy beliefs. Forty-four preservice elementary teachers participated in the study. Analysis of the quantitative (STEBI-b) and qualitative (informal surveys) data revealed that personal science teaching efficacy and science teaching outcome expectancy beliefs increased significantly over the semester. Enactive mastery, cognitive pedagogical mastery, symbolic modeling, and cognitive self-modeling were the major sources of self-efficacy.

    Paranoid ideation is more common in the general population than previously thought, and it is associated with low socioeconomic status. Daily life hassles, self-mastery, and striving to avoid inferiority may partly account for this association, but these factors have not been examined in relation to paranoid thoughts. Two hundred fifteen individuals from the general population completed self-report assessments of paranoid thoughts during the last month, daily life hassles, self-mastery, striving to avoid inferiority, and socioeconomic classification. A greater number of daily hassles, low self-mastery, and insecure striving were all associated with greater levels of paranoid thinking. Each variable was associated with markers of socioeconomic status. This study demonstrates for the first time the association of paranoid thoughts with life hassles, self-mastery, and striving to avoid inferiority. Each of the factors examined may be a plausible candidate to account for why lower socioeconomic status is associated with greater perceptions of threat from other people.

    The purpose of this observational study was to compare the mastery of 12 fundamental movement skills (FMS) and skill components between a treatment-seeking sample of overweight/obese children and a reference sample from the United States. Mastery of six locomotor and six object-control skills (24 components in each subdomain) were video-assessed by one assessor using the test of gross motor development-2 (TGMD-2). The 153 overweight/obese children (mean ± s.d. age = 8.3 ± 1.1 years, BMI z-score = 2.78 ± 0.69, 58% girls, 77% obese) were categorized into age groups (for the underhand roll and strike: 7-8 years and 9-10 years; all other FMS: 6-7 years and 8-10 years) and mastery prevalence rates were compared with representative US data (N = 876) using χ(2) analysis. For all 12 skills in all age groups, the prevalence of mastery was lower among overweight/obese children compared with the reference sample (all P < 0.05). This was consistent for 18 locomotor and upto 21 object-control skill components (all P < 0.05). Differences were largest for the run, slide, hop, dribble, and kick. Specific movement patterns that could be targeted for improvement include positioning of the body and feet, the control or release of an object at an optimal position, and better use of the arms to maintain effective force production during the performance of FMS. Physical activity programs designed for overweight and obese children may need to address deficiencies in FMS proficiency to foster the movement capabilities required for participation in health-enhancing physical activity.

    This paper reports the effects of error-reduced learning on movement components and mastery of overhand throwing in children with and without intellectual disability. Secondary data analysis was performed on two samples of children (typically developing, TD; intellectual disability, ID) who practiced overhand throwing in either an error-reduced (ER) or error-strewn (ES) condition. Movement pattern components were assessed using a sub-skill of Test of Gross Motor Development-2. In TD participants, ER learners displayed improved follow-through while ES learners did not. Among children with ID, ER learners displayed greater improvements of hip/shoulder rotation and follow-through, than ES learners. Discriminant function analysis confirmed that changes in these components differentiated learning groups. Greater percentage of ER, compared to ES, participants progressed to mastery. With suppressed errors, the follow-through component of overhand throwing is likely to emerge, particularly in children with inferior abilities, and cognitive limitations. Error-reduced learning facilitates mastery.

    Full Text Available Exploring students’ background knowledge in pre-reading activities suggests the importance of interaction in the process of meaning making which requires appropriate vocabulary. Although many factors constitute students’ comprehension, vocabulary should be the main concern in EFL reading classes.  Consistence with this premise, the current study was aimed at proving the correlation between students’ vocabulary mastery and their reading achievement at the fourth semester of STKIP Dharma Bakti Lubuk Alung. This correlational study involved 70 students taken through cluster random sampling. Vocabulary and reading test were employed to determine the correlation between students’ vocabulary mastery and their reading comprehension.  Through Correlation of Product Moment, coefficient correlation between two variables was found to be 0.61 with index correlation in r-table was 0.1617 for α= 0.05, suggesting that the coefficient correlation between two variables (rxy t-calculated was bigger than t-table.  It means that H1 was accepted and H0 was rejected. In conclusion, there was a positive correlation between students’ vocabulary mastery and their reading comprehension at the fourth semester students of STKIP Dharma Bakti Lubuk Alung

  5. Self-Esteem and Mastery Trajectories in High School by Social Class and Gender

    2011-01-01

    Using longitudinal data from 769 white adolescents in the Midwest, this research applies a social structure and personality perspective to examine variation in self-esteem and mastery trajectories by gender and SES across the high school years. Analyses reveal that high SES adolescents experience significantly steeper gains in self-esteem and mastery compared to low SES adolescents, resulting in the reversal of SES differences in self-esteem and the emergence of significant SES differences in mastery. Pre-existing gender differences in self-esteem narrow between the 9th and 12th grade because self-esteem increases at a faster rate among girls than boys during high school. These SES and gender differences in self-concept growth are explained by changes in parent-adolescent relationship quality and stress exposure. Specifically, boys and adolescents with lower SES backgrounds experienced steeper declines in parent-adolescent relationship quality and steeper gains in chronic work strain compared to girls and low SES adolescents, respectively.

    There are many factors that shape students' attitudes toward science, technology, engineering and mathematics. This exploratory study of high school students examined the effect of enriching chemistry with math on chemistry students' attitudes toward math and careers involving math. To measure student attitudes, a survey was administered before and after the 18-week chemistry class; results from the chemistry class were compared to survey results from students in an elective science class that did not emphasize mathematics. At the end of the 18-week period, only the chemistry students exhibited more positive views toward their abilities in mathematics and careers that involve mathematics, as compared to their views at the outset of the course. To ensure that chemistry mastery was not hindered by the additional emphasis on math, and that mastery on state end-of-course examinations reflected knowledge acquired during the math-intensive chemistry class, a chemistry progress test was administered at the start and end of the term. This exploratory study suggests that emphasizing mathematical approaches in chemistry may positively influence attitudes toward math in general, as well as foster mastery of chemistry content.

    Neuroimaging studies have become increasingly multimodal in recent years, with researchers typically acquiring several different types of MRI data and processing them along separate pipelines that provide a set of complementary windows into each subject's brain. However, few attempts have been made to integrate the various modalities in the same analysis. Linked ICA is a robust data fusion model that takes multi-modal data and characterizes inter-subject variability in terms of a set of multi-modal components. This paper examines the types of components found when running Linked ICA on a large magnetic resonance imaging (MRI) morphometric and diffusion tensor imaging (DTI) data set comprising 484 healthy subjects ranging from 8 to 85 years of age. We find several strong global features related to age, sex, and intracranial volume; in particular, one component predicts age to a high accuracy (r=0.95). Most of the remaining components describe spatially localized modes of variability in white or gray matter, with many components including both tissue types. The multimodal components tend to be located in anatomically-related brain areas, suggesting a morphological and possibly functional relationship. The local components show relationships between surface-based cortical thickness and arealization, voxel-based morphometry (VBM), and between three different DTI measures. Further, we report components related to artifacts (e.g. scanner software upgrades) which would be expected in a dataset of this size. Most of the 100 extracted components showed interpretable spatial patterns and were found to be reliable using split-half validation. This work provides novel information about normal inter-subject variability in brain structure, and demonstrates the potential of Linked ICA as a feature-extracting data fusion approach across modalities. This exploratory approach automatically generates models to explain structure in the data, and may prove especially powerful for large

    Full Text Available Abstract Background Indigenous peoples in Australia are disadvantaged on all markers of health and social status across the life course. Psychosocial factors are implicated in the aetiology of chronic diseases and in pathways underpinning social health disparities. Minimal research has investigated psychosocial factors and health in Indigenous peoples. This study evaluated associations between mastery, perceived stress, and health-related behaviour for a remote Indigenous population in Australia. Methods Complete data on mastery (the degree to which individuals feel in control of their lives, perceived stress, physical activity, and fruit and vegetable consumption were obtained for 177 participants in a community-based chronic disease risk factor survey. Psychosocial questionnaires were completed as an option during community screening (response rate = 61.9%. Extensive consultation facilitated the cross-cultural adaptation of measures. Results Mastery was inversely correlated with perceived stress measures (p r = -0.47; chronic stress, r = -0.41; and youth stress, r = -0.30. Relationships between mastery and behaviour varied according to age group (p = 0.001 and vegetable consumption (p = 0.005.

    Background:Many researchers agree that students, especially primary students, have learning difficulties on the 'Particulate Nature of Matter' unit. One reason for this difficulty is not considering individual differences for teaching science. In 4MAT model learning, environment is arranged according to individual differences. Purpose:The purpose of this study is to examine (1) the effects of the 4MAT learning model on the7th grade students' academic achievement and motivation on the 'Particulate Nature of Matter' unit and (2) identify student opinions on the 4MAT model. Sample:The sample consists of 235 students (115 experimental, 120 control) in Turkey. Design and methods:Experimental groups were instructed with the 4MAT model while control groups were instructed with a traditional method. Achievement Test (AchToM) and Motivation Scale (MotScl) were administered to students as pre- and post-tests. Moreover, the opinions of students in the experimental groups on the 4MAT model were ascertained through open-ended questions after the application. Results:According to independent t-test results, statistical difference in favour of the experimental groups was detected between the post-AchToM (ES = 1.43; p motivation and participation in the lesson, lessons are more amusing and enjoyable, and the self-confidence of the students increases. Besides these positive opinions, however, a few students stated that the method took too much time, they were not motivated and it did not help them in understanding the subject. Conclusions:The 4MAT model is more effective than traditional method in terms of increasing achievement and motivation. The model takes all learners into account. Thus, the teacher or educator should use the 4MAT model to ensure all students' learning in their classroom.

    It is generally agreed that learners need to acquire digital literacy in order to be able to act as citizens, employees and entrepreneurs in an increasingly digitalized environment. It is also generally agreed that the educational system has to be responsible for educating towards digital literacy....... However, there is no shared conception of the scope and meaning of digital literacy. The overall picture shows two main approaches: The first aims at digital literacy in the sense of Buildung (general education) while the second addresses a wide range of specific skills and competences: From basic...... computer skills over multimodal analysis to social conventions for behavior in online environments. Consequently designs for teaching and learning that aim at learners acquiring digital literacy and the related learning objectives appear as weak defined.

    We study a recently proposed scenario for the early universe: Subluminal Galilean Genesis. We prove that without any other matter present in the spatially flat Friedmann universe, the perturbations of the Galileon scalar field propagate with a speed at most equal to the speed of light. This proof applies to all cosmological solutions -- to the whole phase space. However, in a more realistic situation, when one includes any matter which is not directly coupled to the Galileon, there always exists a region of phase space where these perturbations propagate superluminally, indeed with arbitrarily high speed. We illustrate our analytic proof with numerical computations. We discuss the implications of this result for the possible UV completion of the model.

    The aim of this study was to examine the relationship between mastery motivation and individual and environmental characteristics in school-aged children with congenital hemiplegia. Forty-eight child-caregiver dyads (children's mean age 7y 11mo, SD 2y 4mo; 33 males, 15 females; Manual Ability Classification System [MACS] level I, n=25, and level II, n=23; predominant motor type spastic hemiplegia, n=47) were recruited to this cross-sectional study. Children were assessed using the Melbourne Assessment of Unilateral Upper Limb Function (MUUL) and the Assisting Hand Assessment. Caregivers completed the Dimensions of Mastery Questionnaire, the Parenting Scale, and a demographic questionnaire. Consistent and positive parental disciplinary practices were associated with higher total motivation (p=0.006) and instrumental aspect scores (p=0.009). Children with siblings and from single-parent families experienced greater negative reactions to failure (p=0.006). Children from two-parent families (p=0.018) and with better bimanual performance (p=0.015) demonstrated greater object-oriented persistence. Age, sex, limitations in manual ability (MACS), and movement and body function of the impaired limb (MUUL) did not contribute significantly to mastery motivation. Inconsistent, excessively lax, and verbose parenting practices may discourage children from persevering with challenging tasks. Functional parenting styles, positive discipline practices, and autonomy-supportive strategies for task engagement should be encouraged when intervening with children with cerebral palsy. Parents should be supported to engage in these practices in all aspects of daily activities. © 2013 Mac Keith Press.

    Perceived social support has been established as an important determinant of mortality risk. The perception of parental love and caring reflects the core of social support in the first 20 years of life. In the early 1950s, narrative descriptions of parents were obtained from a sample of healthy undergraduate men at Harvard University who participated in the Harvard Mastery of Stress Study. In a 35-year prospective follow-up investigation, detailed medical and psychological histories and medical records were obtained. Subjects who had illnesses such as coronary artery disease, hypertension, duodenal ulcer, and alcoholism in midlife had used significantly fewer positive words to describe their parents (eg, loving, friendly, warm, open, understanding, sympathetic, just) while in college. This effect was independent of the subject's age, family history of illness, smoking behavior, marital history, and the death or divorce of the subject's parents. Furthermore, 95% of subjects who used few positive words and also rated their parents low in parental caring had diseases diagnosed in midlife, whereas only 29% of subjects who used many positive words and also rated their parents high in parental caring had diseases diagnosed in midlife. Because parents are usually the most meaningful source of love and caring for much of early life, the perception of parental love and caring may play a special role in promoting long-term health. The findings are consistent with the hypothesis that love and caring play an important role in healing.

    The purpose of this investigation was to replicate a test of the mediating functions of mastery and coping and to determine whether the relationships found in the initial test of the model would hold with a sample more heterogenous than the original sample. One hundred women receiving treatment for gynecological cancer participated in the investigation. Of the 14 relationships in the model, only 5 replicated significant paths and had overlapping confidence intervals. Two moderators were proposed to explain the differences between the initial and replication tests of the model and to improve the specificity of the theory.

    Cluster C personality disorder traits have been observed in substance use disorders and linked with poorer outcome. One potential factor which may cause these disturbances in personality function is alexithymia, or the inability to name and express emotion. There may be other proximate factors which moderate the impact of alexithymia on the expression of cluster C traits, such as metacognitive mastery, which is the ability to use knowledge about mental states of self and others to cope with distress and solve social problems. To examine the possibility that mastery mediated the effects of alexithymia on cluster C traits, we assessed each of these constructs using the Metacognitive Assessment Scale Abbreviated, Toronto Alexithymia Scale and SCID II among 58 adults in an early phase of recovery from substance misuse disorders in a residential setting. Results of a multiple regression revealed that, after controlling for symptom severity and severity of substance misuse history, metacognitive mastery moderated the effect of alexithymia on number of cluster C traits. A median split and subsequent ANCOVA revealed that participants with higher levels of alexithymia and poorer metacognitive mastery had more cluster C traits than the other groups. These findings may have clinical implications, suggesting that patients with substance use disorders may benefit from treatment which addresses metacognitive mastery. Published by Elsevier Ltd.

    The purpose of the present study was to examine the hypothesis that a nonlinear relationship exists between a performance-classroom climate and the reading achievement of adolescent students with learning disabilities (LD). Participants were 62 students with LD (Grades 5-9) from public elementary schools in northern Greece. Classroom climate was assessed using the Patterns of Adaptive Learning Styles. Achievement in reading was assessed using a normative reading assessment. Data were analyzed by means of catastrophe theory in which the behavior is predicted as a function of two control variables, the asymmetry factor and the bifurcation factor. Reading achievement (word identification) was predicted by students' ability to decode pseudowords (asymmetry variable) and by a mastery or performance motivational discourse (bifurcation factor). Results indicated that in classrooms with a performance goal structure, the cusp model fit the data and accounted for 54% of the variance in real word identification. In this condition, the association between pseudoword reading and real word reading was nonlinear. When a mastery climate was tested as a bifurcation variable, results indicated that its effect was nonsignificant and that instead the linear model fitted the data more adequately. Thus, increases in a classroom's performance motivational discourse are associated with sudden, unpredictable, and discontinued changes in students' reading performance. © Hammill Institute on Disabilities 2015.

    Full Text Available Vocabulary plays pivotal role in foreign language learning. However, vocabulary teaching and vocabulary learning in TEFL seems to be neglected. The study was aimed to investigate how vocabulary teaching and learning are perceived by teacher and students, strategies to teach and learn the vocabulary, and also influences of students’ vocabulary learning strategy on their vocabulary mastery. Accordingly, a mix method design was employed to one English teacher and 30 junior high school students to reveal the issues being investigated. The findings showed that both teacher and students have positive response on vocabulary teaching and learning. Concerning strategies, it was found that teacher mostly employed Fully-contextual strategy, meanwhile Determination and Metacognitive strategy were found as the most favored VLS chosen by students. The study also confirmed that there is a significant relationship between students’ vocabulary learning strategy and their vocabulary mastery (r-value Discovery = .023 and r-value Consolidating = .000, p<.05. It is recommended for EFL teachers to give a bigger portion to vocabulary in the EFL teaching and to teach vocabulary using the combination of fully-contextual and de-contextual strategy. It is also suggested to introduce students to various kinds of vocabulary learning strategies.

    Full Text Available This study examines the use of Modifed Domino Card as an interesting and enjoyable teaching media which has the necessary aspect of competition and forces the learners easy to learn the vocabulary, store it in memory and recall it (Lebedova: 2011 in improving the fifth year students’ vocabulary mastery at Elementary School. The result of the research shows that Modifed Domino Card can improve the students’ vocabulary mastery. There was an improvement on the mean score of the test. In the frst cycle it was 61.38 and improved to 90 in the second cycle. This technique could make the students pay attention to the lesson properly. It also improved students’ participation in learning vocabulary. They were not shy anymore but were highly motivated to join the instructional process. The English teachers who want to apply Modifed Domino Card should prepare the card well and as interesting as possible and do the following steps: (1 dividing students into group, (2 spreading a set of cards to each group, (3 matching the picture and the defnition, and (4 giving test.

  8. Utilizing measure-based feedback in control-mastery theory: A clinical error.

    Clinical errors and ruptures are an inevitable part of clinical practice. Often times, therapists are unaware that a clinical error or rupture has occurred, leaving no space for repair, and potentially leading to patient dropout and/or less effective treatment. One way to overcome our blind spots is by frequently and systematically collecting measure-based feedback from the patient. Patient feedback measures that focus on the process of psychotherapy such as the Patient's Experience of Attunement and Responsiveness scale (PEAR) can be used in conjunction with treatment outcome measures such as the Outcome Questionnaire 45.2 (OQ-45.2) to monitor the patient's therapeutic experience and progress. The regular use of these types of measures can aid clinicians in the identification of clinical errors and the associated patient deterioration that might otherwise go unnoticed and unaddressed. The current case study describes an instance of clinical error that occurred during the 2-year treatment of a highly traumatized young woman. The clinical error was identified using measure-based feedback and subsequently understood and addressed from the theoretical standpoint of the control-mastery theory of psychotherapy. An alternative hypothetical response is also presented and explained using control-mastery theory. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

With respect to the craftsmanship from several Romanian ethnographic areas, three main chapters organize the present text as regards the origin of the artisans’ knowledge and skills, their craft techniques, and the folk art thus inherited, performed, and transmitted. As will be seen, “mastery” (in this case may reflect various but also interdependent phenomena like dexterity, “gift”, handwork, “the craft theft”, the management of raw materials and their properties, the imagining of an artifact and creativity in its execution, etc. Since all these facts (among others as well are difficult to encompass in a single referential term, choosing the word mastery meets at the same time exigencies of etymology (lat. magister, semantics (mastery as “skillfulness”, “ingenuity”, “ability”… and ethnography (pasărea măiastră, in Romanian “fantastic bird” as a folk artifact

  10. A Mastery Rubric: guiding curriculum design, admissions and development of course objectives.

    Science.gov (United States)

    Tractenberg, Rochelle E; Umans, Jason G; McCarter, Robert J

    This article describes a 'Mastery Rubric' (MR) used to design both the curriculum and the assessments in a new two-year certificate programme intended to train physicians in clinical research skills. The MR for clinical research skills is built around a set of core research skills: critical review of literature; articulation of research objective; development of research design; development of analysis plan; implementation of the study; implementation of the analysis plan and presentation of results. Four distinct levels of performance are described for each skill: beginning, novice, competent and proficient. This rubric outlines and provides a path to mastery of the clinical research skills the certificate programme was designed and funded to target. Using the rubric to design the curriculum ensures that courses will provide instruction in key domains, promotes assessment that demonstrates development in the target skills and knowledge, and encourages reflection and cognitive self-monitoring in the students. It is a flexible, criterion-referenced definition of 'success' for students as well as the programme itself. The criteria are characterised in terms of the skills, habits of mind and organisational principles that can foster excellence in clinical research, but the approach can be generalised.

    Simulation-based mastery learning (SBML) improves procedural skills among medical trainees. We employed an SBML method that includes an asynchronous knowledge acquisition portion and a hands-on skill acquisition portion with simulation to assess senior medical student performance and retention of the following 6 core clinical skills: (a) ultrasound-guided peripheral intravenous placement, (b) basic skin laceration repair, (c) chest compressions, (d) bag-valve mask ventilation, (e) defibrillator management, and (f) code leadership. Seven emergency medicine (EM) faculty members developed curricula, created checklists, and set minimum passing standards (MPSs) to test mastery of the 6 skills. One hundred thirty-five students on an EM clerkship were pretested on all 6 skills, viewed online videos asynchronously followed by a multiple choice computer-based skill-related quiz, received one-on-one hands-on skill training using deliberate practice with feedback, and were posttested until MPS was met. We compared pretest and posttest performance. We also retested, unannounced, a convenience sample (36%) of students from 1 to 9 months postintervention to assess skill retention. All students passed each quiz. The percentage of students who reached each MPS increased significantly (P training necessary for residency readiness.

A questionnaire with 32 items was answered by 174 students/instructors/coordinators of the Media in Education and Physics courses, of two federal universities, between 2011 and early 2012. The interview with a coordinator was transcribed and related to the data systematised in tables and graphs. Interpretative analysis, in an open dialogue with the references and with the data from the Universidade Aberta do Brasil (UAB - Open University of Brazil site resulted in the final considerations. These suggest that the use and/or mastery of VLEs by students are important, and the specificities of these uses subsidise studies and publications, still in a small number in the literature in this area of knowledge. The work reflects the development of the Open Distance Education System, conducted with strong popular participation, as a response to the challenge posed to the educational policies for expanding the public provision of higher education, also using VLEs for this purpose.

    Among the purposes of physics learning at high school is to master the physics concepts and cultivate scientific attitude (including critical attitude), develop inductive and deductive reasoning skills. According to Ennis et al., inductive and deductive reasoning skills are part of critical thinking. Based on preliminary studies, both of the competence are lack achieved, it is seen from student learning outcomes is low and learning processes that are not conducive to cultivate critical thinking (teacher-centered learning). One of learning model that predicted can increase mastery concepts and train CTS is inquiry learning model aided computer simulations. In this model, students were given the opportunity to be actively involved in the experiment and also get a good explanation with the computer simulations. From research with randomized control group pretest-posttest design, we found that the inquiry learning model aided computer simulations can significantly improve students' mastery concepts than the conventional (teacher-centered) method. With inquiry learning model aided computer simulations, 20% of students have high CTS, 63.3% were medium and 16.7% were low. CTS greatly contribute to the students' mastery concept with a correlation coefficient of 0.697 and quite contribute to the enhancement mastery concept with a correlation coefficient of 0.603.

    To determine the extent to which children's mastery motivation predicts occupational performance outcomes following upper limb intervention (ULI). In this cohort study, participants received 45 hours of ULI, either in an intensive group-based or distributed individualized model. The Dimensions of Mastery Questionnaire (DMQ) measured mastery motivation at baseline. Occupational performance outcomes were assessed at baseline and 13 weeks' post-intervention using the Canadian Occupational Performance Measure (COPM). Multivariable models determined the contribution of mastery motivation to COPM outcome irrespective of group membership. Forty-two children with congenital hemiplegia (29 males, 13 females; mean age 7y 8mo [SD 2y 2mo]; range 5y 1mo-12y 8mo; Manual Ability Classification System [MACS] I=20 and II=22; predominant motor type unilateral spastic n=41) participated in the study. Significant gains were seen in COPM performance and satisfaction scores (p<0.001) post-intervention with no between group differences. Children who had greater persistence with object-oriented tasks (p=0.02) and better manual ability (p=0.03) achieved higher COPM performance scores at 13 weeks. Children's persistence on object-oriented tasks was the strongest predictor of COPM satisfaction (p=0.01). Children's persistence with object-oriented tasks as well as manual abilities needs to be considered when undertaking ULI. Predetermining children's motivational predispositions can assist clinicians to tailor therapy sessions individually based on children's strengths, contributing to effective engagement in ULI. © 2014 Mac Keith Press.

    If people's goals and evaluative standards were aligned, then individuals with mastery-based goals should, theoretically, primarily rely on temporal comparison information (i.e., on how they performed relative to before). In contrast, individuals with performance-based goals should rely on social comparison information (i.e., on how they performed relative to others). However, across three studies, we explored a misalignment phenomenon we call "the overpowering effect of social comparison information" (TOESCI). We found that, irrespective of individuals' specific achievement goal (performance-based vs. mastery-based), there is a consistent, dominant reliance on social comparisons over temporal comparisons in their performance self-evaluations. These findings suggest that one's goals and evaluation criteria do not always align-that explicitly endorsing mastery-based goals does not necessarily lead one to rely on temporal comparison information over social comparison information. Only after receiving an explicit reminder to consider their mastery-based goal did participants align their goal and performance self-evaluation criteria.

    1999-12-01

    In order to examine the extent to which parents' levels of education, financial resources, self-esteem, and their mastery-orientation versus task-avoidance are associated with their parenting styles and parental stress, data from two studies were analyzed. In Study I, parents of 105 6 to 7-year old children were asked to fill in scales measuring their parenting styles and parental stress, mastery-orientation, financial resources, and their level of education. In Study II, 235 parents were asked to fill in the same scales. An identical pattern of results was found in the two studies. Parents' self-esteem and their use of mastery-oriented strategy were found to be associated with authoritative parenting and low parental stress, whereas parents' low level of education was related to an authoritarian parenting style. The results further showed that the impact of parents' self-esteem on authoritative parenting and parental stress was partly mediated by their use of a mastery-oriented strategy.

    2010-10-01

    This study investigated sexual drive and satisfaction of Chinese gynecologic cancer survivors. It also examined the extent to which personal mastery, adaptive coping, and perceived spousal support would exert direct and/or indirect influences on sexual outcomes. The cancer survivor group included 134 Chinese women who had received treatment for gynecologic cancer, while the healthy control group included 105 Chinese women who did not have a known history or current diagnosis of cancer. Compared to healthy women, cancer survivors reported lower levels of sexual drive and sexual satisfaction. Among sexually active participants, cancer survivors relative to healthy women engaged in less masturbation, less kissing and caressing, and less sexual fantasy in the past month. Hierarchical multiple regression analyses showed that mastery and spousal support, but not adaptive coping, had a direct influence on sexual outcomes in cancer survivors. Contrary to moderation hypotheses, the three psychological factors did not interact with each other to influence sexual drive and satisfaction. Mediation analyses showed that spousal support fully mediated the influence of mastery on sexual satisfaction. Routine assessment of sexual functioning prior to and following treatment of gynecologic cancer is suggested. Sexual rehabilitation should also aim to enhance personal mastery and spousal support.

    2009-07-01

    American Indian and Alaska Native (AIAN) women have endured a history of colonial oppression in the United States. Current manifestations of colonization include an epidemic of violence toward AIAN women, who often are sexually and physically abused from early on in life. Such violence may erode AIAN women's sense of agency or mastery and contribute to their poor physical and mental health outcomes. AIAN women who identify as lesbian, bisexual, or "two-spirit" appear to experience disproportionate levels of violence and may be particularly vulnerable to disparities in health outcomes. In this study, 152 sexual minority AIAN women were interviewed as part of an investigation addressing the health concerns of two-spirit persons. Participants reported disturbingly high prevalence of both sexual (85%) and physical (78%) assault, both of which were associated with worse overall mental and physical health. These relationships generally were mediated by a diminished sense of control or mastery. The need to indigenize the concept of mastery is discussed, as is the urgency of interventions to work toward decreasing levels of abuse and increasing mastery among sexual minority AIAN women.

    Clients with HIV infection have been conceptualized as a resilient population. Although a few researchers have documented resilience among clients with HIV infection, a theory of resilience in the context of HIV infection has not been developed. The purpose of this study was to describe the process by which resilience occurs for clients in the context of HIV infection. Grounded theory methodology was used to sample and analyze data from 15 qualitative interviews with adults with HIV infection. Data were collected until saturation was reached. A theory, motivation, management, and mastery, a description of the process by which resilience occurs in the context of HIV infection, emerged from the data. Many clients living with HIV infection are resilient, despite the physical, psychological, and social challenges of this chronic illness. Nursing interventions to promote resilience among clients with HIV infection should be directed toward identification of client motivation factors and disease management strategies that may influence health outcomes of people living with HIV infection.

    In a climate of impending staff crisis related to looming retirements, challenging recruitment realities and the demographic realities of an aging population creating increased demand for services, the Interior Health Authority in British Columbia recognized the need for the creation of a workplace that would both attract and retain engaged employees. One of the identified ways of achieving this was to provide professional development that was also personal development for each individual in the organization. This personal /professional development involved the creation and implementation of a program in personal leadership for all front-line staff of the organization. This learning, it was believed, would lead to the transformation of the work environment and, subsequently, the culture of the workplace. This article describes the development and implementation of a pilot program in personal leadership within Interior Health. Results to date demonstrate the promise of this program to effect profound cultural change through the development of personal mastery and personal leadership...for everyone.

  2. Metapsychology or metapsychologies? Some comments on Paul Denis's paper 'The drive revisited: mastery and satisfaction'.

    Sapisochin, Gabriel

    2016-06-01

    In this commentary on Paul Denis's paper 'The drive revisited: mastery and satisfaction', the author defends the idea of a plurality of metapsychologies that must be contrasted with and distinguished from each other while avoiding incompatible translations between models. In this connection he presents various theoretical approaches to aggression and the death drive, and demonstrates the differences between the drive model and the model underlying the theory of internalized object relations. The author holds that the concept of the internal object differs from Freud's notion of the representation (Vorstellung). He also considers that the imago as defined by Paul Denis in fact corresponds to the concept of the internal object. Lastly, he addresses the complex issue of listening to archaic forms of psychic functioning and their non-discursive presentation within the analytic process, which affects the transference-countertransference link.

    Faculty in a 4-year baccalaureate nursing program were concerned with students' failure to retain the patient care skills of vital signs, breath sounds, and heart sounds learned in freshman and sophomore courses and consequent inability to transfer these high-frequency skills into the clinical setting. Because nursing is a practice profession, new graduates must be prepared to demonstrate specific competencies that are designed to improve practice. To address faculty concerns, support more positive learning outcomes, and engage in evidence-based nursing education, faculty developed and implemented an assignment that incorporated deliberate practice and peer mentoring into a sophomore course on the essentials of nursing practice. The purpose of this article is to describe the rationale, development and implementation, and feedback for a deliberate practice and peer mentoring assignment designed to enhance skill mastery and retention.

    1975-05-01

    The four-year-old children of Head Start (two-year-classes of 90 for 1969-71 and 72 for 1971-72) performed on a test of perceptual identification approximately as well as four-year-old nursery-school children of parents predominantly of college background. On the other hand, only 28.9% and 19.4% of the children of Head Start, as compared with 87.9% and 90.2% of the children of the nursery-school pointed correctly to all six of the blocks when the examiner named the colors. Also, only 25.6% and 23.6% of those of Head Start, as compared with 81.8% and 76.5% of those of the nursery school, named the colors of all six blocks as they were designated by the examiners. Sex differences and race differences, except in the case of brown, among the children of Head Start were negligible and not significant. Somewhat more children showed semantic mastery for the warn colors, orange and red, than for the cool colors, blue and green. The finding of a deficiency in semantic mastery for such an elementary abstraction as color is highly dissonant with the contention of many students of sociological linguistics that children of poverty, and especially black children of poverty, are without cognitive or linguistic deficit, and that they fail in school only because they use a dialect differing from standard English. The finding is quite consonant with the contention that children of poverty do have a cognitive and linguistic deficit which may, and probably does, derive from the rearing conditions in their homes during the preschool years.

  5. Social class and preschool language skill: V. Cognitive and semantic mastery of number.

    Kirk, G E; Hunt, J; Volkmar, F

    1975-08-01

    This study was done to test the validity of two hypotheses of why children, and especially black children, of families of the poverty sector commonly fail in school. Sociologists deny for them either a cognitive or a linguistic deficit, and blame their failures on having to master the unfamiliar dialect of standard English while learning to read. The authors, on the other hand, blame the failures on inadequacies of early preschool experience that result in such deficits as one in semantic mastery of various elementary abstractions. In 1970-1971, 87 four-year-old students (58 black and 29 white) of Head Start and 33 of nursery school were examined with a five part test of number identification. In 1971-1972, the study was repeated with 69 four-year-olds of Head Start and 46 of the nursery school. A much smaller percentage of Head Start than of nursery school identify the numbers of blocks from 2 through 4 by either the heard or spoken mode of number identification. For numbers 5 and 6, most children of both classes fail. The evidence for a semantic deficit for number is very strong. The evidence indicates also a deficit in the span of apprehension and suggests the existence of class differences in the power of examiner demands for heard and for spoken identification to elicit the counting strategy. Evidence of sex differences in semantic mastery of number is absent, and among Head Start children, race differences lack statistical significance. These findings are highly dissonant with the contention of the sociolinguists that no cognitive or linguistic deficits exist and uncovering them can be helpful in guiding compensatory education.

    The four-year-old children of Head Start (two-year-classes of 90 for 1970-71 and 67 for 1971-72) performed on a test of perceptual identification of a sample of six positions approximately as well as did four-year-olds of parents with predominantly college backgrounds. On the other hand, only 22% and 16% of those of Head Start as compared with 70% and 67% of those of the nursery school placed blocks in all six positions that they heard the examiner name, and only 12% and 9% of the former as compared with 45.5% and 44.9% of the latter gave appropriate names for all the six positions designated by the examiner. Sex differences and differences between black and white children of Head Start were negligible and not significant. Somewhat more children of both Head Start and the nursery school showed semantic mastery based on both heard and spoken identification for positions based on body-object relations (in, on, and under) than for those based on object-object relations (in fromt of, between, and in back of). The fact that the children of Head Start perform so much less well than those of the nursery school on the test semantic mastery for position information is highly dissonant with the contention that children of poverty are without either cognitive or linguistic deficit, but quite consonant with the contention that they suffer a deficit that may well and probably does result from the rearing conditions in their homes during the preschool years.

    The study examined participation in the Basic Skills Faculty Development Workshops (BSW) offered by the Physician Assistant Education Association (PAEA). The aim was to determine the effects of participation on perceived mastery of teaching skills and job satisfaction. The 1,290 faculty and program director members of PAEA were invited to complete an electronic survey regarding their past participation in a BSW, levels of satisfaction with various aspects of their work, and their perception of their level of mastery of various teaching skills. Additionally, those who had participated in these workshops completed a section on colleague relationships that were developed or strengthened through workshop participation. Approximately half (n = 248) of the 493 respondents had participated in a BSW. Mean scores for satisfaction with salary, rank, position, and overall satisfaction did not differ significantly according to BSW participation. Perceived mastery of various teaching skills was significantly higher for nonattendees of BSW. However, controlling for "years in physician assistant education" nullified that association. Attendees reported a mean of 1.02 (SD = 1.47) new mentoring relationships and 2.45 (SD = 2.97) new peer relationships. Satisfaction with current position was significantly positively correlated with the number of colleague relationships. The number of new and strengthened mentor relationships correlated significantly with perceived mastery of advising students. Basic Skills Workshop attendees experience acceleration in their perceived mastery of teaching skills, closing the proficiency gap between them and their more-experienced colleagues who did not attend a Basic Skills Workshop. Also, participation is associated with an increased number of colleague relationships, which has a positive effect on satisfaction.

    Full Text Available The paper reports a classroom action research that aimed to determine the impact of a Content and Language Integrated Learning on the mastery of vocabulary and of course contents of a group of students in the Accounting Department of Universitas Ma Chung. It also intended to identify their opinions about the effectiveness of such approach. To achieve these objectives, a Time Series Design was used in a Classroom Action Research framework to introduce an adjunct class to the accounting class. The baseline data in the form of their vocabulary mastery and knowledge of the course contents were gained before the adjunct session was given. Then, the adjunct sessions were given for a period of two months. A few tests were administered to measure their progress in the mastery of vocabulary and course contents. A comparison was then drawn between the scores of the baseline data and the subsequent measures. In general, although they gained better mastery of new words, they failed to utilize them to increase their mastery of the course contents. Further exploration into the interview data reveals that most of them did not feel any significant assistance in mastering the course contents, although many of them admitted the benefit of mastering new vocabulary. There are some possible causes of the results. First, the limited duration of the adjunct sessions was felt to hinder the effectiveness. Second, the explanation in the adjunct sessions were not matched quite well with the focus during the main content course. On the basis of the results, the recommended points are the matching between the emphasis of both classes, and the lengthening of the duration of the adjunct sessions.

    Previous and more recent work of analyzing structural changes in the brain suggest that certain brain regions such as the frontal lobe are among the brain regions profoundly affected by the aging process across males and females. Also, a unified model of structural changes in a normally aging brain is still lacking. The present study investigated age-related structural brain changes in gray matter from young to early middle-age adulthood for males and females. Magnetic resonance images of 215 normal and healthy participants between the ages of 21–45 years were acquired. Changes in gray matter were assessed using voxel-based morphometry and gray matter volumetric analysis. The results showed significant decrease in gray matter volume between the youngest and oldest groups in the following brain regions: frontal, temporal, and parietal lobes. Grey matter loss in the frontal lobe was among the most widespread of all brain regions across the comparison groups that showed significant age-related changes in grey matter for both males and females. This work provides a unique pattern of age-related decline of normal and healthy adult males and females that can aid in the future development of a unified model of normal brain aging.

    2012-11-22

    Estimation of pharmacokinetic parameters after intermittent intravenous infusion (III) of antibiotics, such as aminoglycosides or vancomycin, has traditionally been a difficult subject for students in clinical pharmacology or pharmacokinetic courses. Additionally, samples taken at different intervals during repeated dose therapy require manipulation of sampling times before accurate calculation of the patient-specific pharmacokinetic parameters. The main goal of this study was to evaluate the effectiveness of active learning tools and practice opportunities on the ability of students to estimate pharmacokinetic parameters from the plasma samples obtained at different intervals following intermittent intravenous infusion. An extensive reading note, with examples, and a problem case, based on a patient's chart data, were created and made available to students before the class session. Students were required to work through the case before attending the class. The class session was devoted to the discussion of the case requiring active participation of the students using a random participation program. After the class, students were given additional opportunities to practice the calculations, using online modules developed by the instructor, before submitting an online assignment. The performance of students significantly (P students further improved (P students scored 82.6% in a formal mid-term examination, suggesting significant retention of the materials. Despite being a difficult subject, students achieve mastery of pharmacokinetic calculations for the topic of intermittent intravenous infusion when appropriate active learning strategies and practice opportunities are employed.

    All football teams that compete within the F. A. Premier League possess an academy, whose objective is to produce more and better home-grown players that are capable of playing professionally. These young players spend a large amount of time with their coach, but little is known about player’s perception of the coach–athlete relationship within F. A. Premier League Academies. The objectives of this study were to examine whether perceptions of the coach–athlete relationship changed over six months and if the coach–athlete relationship predicted self-reported goal achievement among F. A. Premier League academy players. This study included cross-sectional (n = 104) and longitudinal (n = 52) assessments, in which academy soccer players completed a measure of the coach–athlete relationship and goal achievement across either one or two time periods. The cross-sectional data were subjected to bivariate correlations, whereas the longitudinal data were analyzed using multiple regressions. Perceptions of the coach–athlete relationship remained stable over time. The coach–athlete relationship predicted the achievement of mastery goals six months later. Enhancing the quality of the coach–athlete relationship among elite adolescent athletes appears to be a suitable way of maximizing mastery achievement goals, particularly among developmental athletes who participate in team sports.

Conversely, students who show good motivation skills, optimism and perseverance are more focused on tasks and ‘mastery oriented’ (derived from Mastery Orientation, MO. The purpose of this study was to develop a self-report measurement of LH and MO - the Learned Helplessness Questionnaire (LHQ - for the Italian scholastic context. We translated and adapted a student self-evaluation register, the Student behaviour checklist, and administered the questionnaire to Italian students in order to provide a preliminary factor structure. Exploratory factor analyses conducted support a two-factor model and acceptable internal reliability of the Italian LHQ.The results encourage the conduction of further analysis to assess the psychometric characteristics of the LHQ in depth.

    This fifteenth volume of the Poincare Seminar Series, Dirac Matter, describes the surprising resurgence, as a low-energy effective theory of conducting electrons in many condensed matter systems, including graphene and topological insulators, of the famous equation originally invented by P.A.M. Dirac for relativistic quantum mechanics. In five highly pedagogical articles, as befits their origin in lectures to a broad scientific audience, this book explains why Dirac matters. Highlights include the detailed "Graphene and Relativistic Quantum Physics", written by the experimental pioneer, Philip Kim, and devoted to graphene, a form of carbon crystallized in a two-dimensional hexagonal lattice, from its discovery in 2004-2005 by the future Nobel prize winners Kostya Novoselov and Andre Geim to the so-called relativistic quantum Hall effect; the review entitled "Dirac Fermions in Condensed Matter and Beyond", written by two prominent theoreticians, Mark Goerbig and Gilles Montambaux, who consider many other mater...

    2017-05-01

    This 20-year prospective longitudinal study focuses on the contribution of mastery motivation and self-regulation to adult outcomes for individuals with Down syndrome. In earlier phases of the research, 25 participants completed measures of cognitive ability, mastery motivation and self-regulation in childhood (4 to 6 years) and adolescence (11 to 15 years). In the adult phase reported here, self-determination and adaptive behavior were assessed in 21 of the original participants at age 23 to 26 years. Mastery motivation and self-regulation made unique contributions to adult outcomes, over and above the effects of cognitive ability. The findings provide powerful evidence about the important role of child and adolescent mastery motivation and self-regulation for the adult lives of individuals with Down syndrome.

    White, Kristin

    2010-08-01

    This short paper looks at Freud's use of the term 'Bemächtigungstrieb' and its translation by Strachey as 'instinct for mastery' when Freud was describing the motives behind his grandson's game with the wooden reel and string in Beyond the Pleasure Principle. The word 'Macht' [power], which is contained in the word 'Bemächtigung' points to Freud's difficult relationship with Alfred Adler, whose early theories on the aggressive drive and later theories on 'striving for power' were initially rejected by Freud. Looking at the changes in Freud's reception of Adlerian terms, some of which he later integrated into his own theory, throws light on his choice of the word 'Bemächtigungstrieb' in 1920, when he was just beginning to introduce his thoughts on the death instinct. A slightly different translation of the word 'Bemächtigungstrieb', one which takes these historical and theoretical aspects into account, could make these connections clearer for the English reader.

    2013-06-01

    Full Text Available The aim of language learning is not only to achieve an academic success carried out by a fluent speaking; mastering the grammar and vocabulary but it should also focus on the psychological comfort and the intrinsic readiness of the students to participate in their education - to receive and perform. The learners’ self-esteem plays the fundamental role in any language classroom but gaining it is the task on its own and can be quite a challenge for the teachers. How students feel is closely related to their ability to learn. Teachers’ task is thus not only to provide knowledge and information but first of all they should immerse themselves into the student’s mind and discover the best way to awake learner’s will to communicate. This paper focuses on two kinds of aspects participating on the emotional state of the learner, academic and psychological. The students of two different levels of English have answered the questionnaire, assessing their attitude, anxiety and motivation towards learning English. Each opinion has been evaluated and put into relationship with the ability to relax, understand, learn and enjoy at the same time. Their analyses have become the base of several teaching techniques that would build and encourage the students’ confidence as the main condition to start any cognitive process. If confidence is the cause or the outcome of mastering a foreign language was the question asked and answered in this work. Confidence mastery has thus played the fundamental role in the present survey.

    The PPDP learning strategy in this research is the acronym of Practicum method, Presentation-discussion method, Demonstration method, and Presentation-discussion method. This study aims to describe the effect of applying PPDP learning strategies to mastery of high school students’ concepts on photosynthesis topic. The research method is a weak experiment, with the research design “The One-Group Pretest-Postetst Design”. The implementation of the study involved 35 students in one of the high schools in the city of Palembang. The research instrument used is in the form of test equipment, assessment rubric and questionnaire. Data were analyzed using Microsoft Excel and SPSS 24 Program. The statistical result showed that PPDP learning strategy had an effect on improving conceptual and Effective on the achievement of the value on the minimum criteria set by the school. This is due to the transformation of knowledge from hands-on to minds-on through the discovery of facts about the concept of photosynthesis. This fact leads to the construction of further understanding through cognitive sharing when the activities of the discussions formed similarity and consolidation of the concept of photosynthesis intact. In addition, demonstration activities also cause students’ logic of thinking to develop through observation of factors that may affect the rate of photosynthesis. This PPDP learning strategy can be utilized by teachers in explaining photosynthetic topic.

    Full Text Available The purpose of the present study was to determine the effect of a structured, mastery motivation physical education climate and an unstructured physical activity climate on time spent on task in a small sample of preschool children. Children enrolled in a public, federal-subsidized childcare center (N= 12 participated in two 45 minute physical activity programs within the school day. The structured climate consisted of a biweekly program of motor skill instruction that was based upon the key principles of a mastery motivational climate. The unstructured program was a daily 45 minute free play environment. Actigraph accelerometers monitored children’s participation in physical activity and time-on task was observed by a momentary time sampling technique. Results showed that time on-task significantly improved following a mastery motivational climate, and children spent 36% of their time in moderate-to-vigorous activity in this climate.  In contrast, time on-task did not significantly improve following participation in a free play environment and participants spent a majority of their time in sedentary behavior and accumulated no vigorous physical activity. Our results indicate that participation in physical activity impacts a preschooler’s ability to stay on task and the amount of physical activity accumulated during physical activity programming is dependent upon the climate delivered.

    Full Text Available Abstract Background Choice promotes the experience of autonomy, which enhances intrinsic motivation. Providing a greater choice of traditional active toys may increase children's activity time. Mastery also increases intrinsic motivation and is designed into exergames, which may increase play time of a single exergame, reducing the need for choice to motivate activity compared to traditional active toys. Providing both choice and mastery could be most efficacious at increasing activity time. The energy expenditure (EE of an active play session is dependent on the duration of play and the rate of EE during play. The rate of EE of exergames and the same game played in traditional fashion is not known. The purpose was to test the basic parameters of choice and mastery on children's physical activity time, activity intensity, and energy expenditure. Methods 44 children were assigned to low (1 toy or high (3 toys choice groups. Children completed 60 min sessions with access to traditional active toys on one visit and exergame versions of the same active toys on another visit. Results Choice had a greater effect on increasing girls' (146% than boys' (23% activity time and on girls' (230% than boys' (minus 24% activity intensity. When provided choice, girls' activity time and intensity were no longer lower than boys' activity time and intensity. The combination of choice and mastery by providing access to 3 exergames produced greater increases in physical activity time (1 toy 22.5 min, 3 toys 41.4 min than choice alone via access to 3 traditional games (1 toy 13.6 min, 3 toys 19.5 min. Energy expenditure was 83% greater when engaging in traditional games than exergames. Conclusions Boys and girls differ in their behavioral responses to autonomy supportive environments. By providing girls with greater autonomy they can be motivated to engage in physical activity equal to boys. An environment that provides both autonomy and mastery is most efficacious at

    Our current understanding of what results in effective simulation-based training is restricted to the physical practice and debriefing stages, with little attention paid to the earliest stage: how learners are prepared for these experiences. This study explored the utility of Web-based observational practice (OP) -featuring combinations of reading materials (RMs), OP, and collaboration- to prepare novice medical students for a simulation-based mastery learning (SBML) workshop in central venous catheterization. Thirty medical students were randomized into the following 3 groups differing in their preparatory materials for a SBML workshop in central venous catheterization: a control group with RMs only, a group with Web-based groups including individual OP, and collaborative OP (COP) groups in addition to RM. Preparation occurred 1 week before the SBML workshop, followed by a retention test 1-week afterward. The impact on the learning efficiency was measured by time to completion (TTC) of the SBML workshop. Web site preparation behavior data were also collected. Web-based groups demonstrated significantly lower TTC when compared with the RM group, (P = 0.038, d = 0.74). Although no differences were found between any group performances at retention, the COP group spent significantly more time and produced more elaborate answers, than the OP group on an OP activity during preparation. When preparing for SBML, Web-based OP is superior to reading materials alone; however, COP may be an important motivational factor to increase learner engagement with instructional materials. Taken together, Web-based preparation and, specifically, OP may be an important consideration in optimizing simulation instructional design.

    Multi-atlas labeling has come in wide spread use for whole brain labeling on magnetic resonance imaging. Recent challenges have shown that leading techniques are near (or at) human expert reproducibility for cortical gray matter labels. However, these approaches tend to treat white matter as essentially homogeneous (as white matter exhibits isointense signal on structural MRI). The state-of-the-art for white matter atlas is the single-subject Johns Hopkins Eve atlas. Numerous approaches have attempted to use tractography and/or orientation information to identify homologous white matter structures across subjects. Despite success with large tracts, these approaches have been plagued by difficulties in with subtle differences in course, low signal to noise, and complex structural relationships for smaller tracts. Here, we investigate use of atlas-based labeling to propagate the Eve atlas to unlabeled datasets. We evaluate single atlas labeling and multi-atlas labeling using synthetic atlases derived from the single manually labeled atlas. On 5 representative tracts for 10 subjects, we demonstrate that (1) single atlas labeling generally provides segmentations within 2mm mean surface distance, (2) morphologically constraining DTI labels within structural MRI white matter reduces variability, and (3) multi-atlas labeling did not improve accuracy. These efforts present a preliminary indication that single atlas labels with correction is reasonable, but caution should be applied. To purse multi-atlas labeling and more fully characterize overall performance, more labeled datasets would be necessary.

    Instructor-led simulation-based mastery learning of advanced cardiac life support (ACLS) skills is an effective and focused approach to competency-based education. Directed self-regulated learning (DSRL) may be an effective and less resource-intensive way to teach ACLS skills. Forty first-year internal medicine residents were randomized to either simulation-based DSRL or simulation-based instructor-regulated learning (IRL) of ACLS skills using a mastery learning model. Residents in each intervention completed pretest, posttest, and retention test of their performance in leading an ACLS response to a simulated scenario. Performance tests were assessed using a standardized checklist. Residents in the DSRL intervention were provided assessment instruments, a debriefing guide, and scenario-specific teaching points, and they were permitted to access relevant online resources. Residents in the IRL intervention had access to the same materials; however, the teaching and debriefing were instructor led. Skills of both the IRL and DSRL interventions showed significant improvement after the intervention, with an average improvement on the posttest of 21.7%. After controlling for pretest score, there was no difference between intervention arms on the posttest [F(1,37) = 0.02, P = 0.94] and retention tests [F(1,17) = 1.43, P = 0.25]. Cost savings were realized in the DSRL intervention after the fourth group (16 residents) had completed each intervention, with an ongoing savings of $80 per resident. Using a simulation-based mastery learning model, we observed equivalence in learning of ACLS skills for the DSRL and IRL conditions, whereas DSRL was more cost effective.

    The purpose of this study was to examine the multiple mediational roles of academic social comparison directions (upward academic social comparison and downward academic social comparison) on the relationships between achievement goal orientations (i.e., mastery goals, performance-approach goals, and performance-avoidance goals) and subjective well-being (SWB) in school (school satisfaction, school affect) in adolescent students in China. A total of 883 Chinese adolescent students (430 males; Mean age = 12.99) completed a multi-measure questionnaire. Structural equation modeling was used to examine the hypotheses. Results indicated that (1) mastery goal orientations and performance-approach goal orientations both showed a statistically significant, positive correlation with SWB in school whereas performance-avoidance goal orientations showed a statistically significant, negative correlation with SWB in school among adolescents; (2) upward academic social comparisons mediated the relation between the three types of achievement goal orientations (i.e., mastery goals, performance-approach goals, and performance-avoidance goals) and SWB in school; (3) downward academic social comparisons mediated the relation between mastery goal orientations and SWB in school as well as the relation between performance-avoidance goal orientations and SWB in school. The findings suggest possible important cultural differences in the antecedents of SWB in school in adolescent students in China compared to adolescent students in Western nations.

    2016-01-01

    CONSTRUCT: In this study we describe a multidimensional scaling (MDS) exercise to validate the curricular elements composing a new Mastery Rubric (MR) for a curriculum in evidence-based medicine (EBM). This MR-EBM comprises 10 elements of knowledge, skills, and abilities (KSAs) representing our institutional learning goals of career-spanning engagement with EBM. An MR also includes developmental trajectories for each KSA, beginning with medical school coursework, including residency training, and outlining the qualifications of individuals to teach and mentor in EBM. The development was not part of the validation effort, as our curriculum is focused at a single stage (undergraduate medical students). An MR comprises the desired KSAs for an entire curriculum, together with descriptions of a learner's performance and/or capabilities as they develop from novice to proficiency of the curricular target(s). The MR construct is intended to support curriculum development or refinement by capturing the KSAs that support the articulation of concrete learning goals; it also promotes assessment that demonstrates development in the target KSAs and encourages reflection and self-directed learning throughout the learner's career. Two other MRs have been published, and this is the first one specific to teaching and learning in medicine; this is also the first one created specifically to evaluate an existing curriculum. To validate the dispersion of the elements of the EBM curriculum, the nine clinical instructors in the EBM two-course curriculum completed an MDS exercise, rating the similarities of the 10 curricular elements. MDS is a mathematical approach to understanding relationships among concepts/objects when these relationships are difficult to quantify. Eliciting similarity ratings biased the responses toward the null hypothesis (that the elements are not different). MDS results suggested that the MR represents 10 different, although related, facets of the construct

    The purpose of this study is to identify gender-based concept mastery differences of junior high school students after the implementation of multiple intelligences-based integrated earth and space science learning. Pretest-posttest group design was employed to two different classes at one of junior high school on eclipse theme in Tasikmalaya West Java: one class for boys (14 students) and one class of girls (18 students). The two-class received same treatment. The instrument of concepts mastery used in this study was open-ended eight essay questions. Reliability test result of this instrument was 0.9 (category: high) while for validity test results were high and very high category. We used instruments of multiple intelligences identification and learning activity observation sheet for our analysis. The results showed that normalized N-gain of concept mastery for boys and girls were improved, respectively 0.39 and 0.65. Concept mastery for both classes differs significantly. The dominant multiple intelligences for boys were in kinesthetic while girls dominated in the rest of multiple intelligences. Therefor we concluded that the concept mastery was influenced by gender and student’s multiple intelligences. Based on this finding we suggested to considering the factor of gender and students’ multiple intelligences given in the learning activity.

    Online game addiction (OGA) has attracted greater attention as a serious public mental health issue. However, there are only a few brain magnetic resonance imaging studies on brain structure about OGA. In the current study, we used voxel-based morphometry (VBM) analysis and tract-based spatial statistics (TBSS) to investigate the microstructural changes in OGA and assessed the relationship between these morphology changes and the Young's Internet Addiction Scale (YIAS) scores within the OGA group. Compared with healthy subjects, OGA individuals showed significant gray matter atrophy in the right orbitofrontal cortex, bilateral insula, and right supplementary motor area. According to TBSS analysis, OGA subjects had significantly reduced FA in the right genu of corpus callosum, bilateral frontal lobe white matter, and right external capsule. Gray matter volumes (GMV) of the right orbitofrontal cortex, bilateral insula and FA values of the right external capsule were significantly positively correlated with the YIAS scores in the OGA subjects. Our findings suggested that microstructure abnormalities of gray and white matter were present in OGA subjects. This finding may provide more insights into the understanding of the underlying neural mechanisms of OGA.

    2010-08-01

    Gerontological social workers and other health professionals are often dealing with older adults in psychological distress. Greater clarity on the relationship between stress and psychological distress will enhance the efficacy of outreach and treatment initiatives for older adults. This study explored the underlying causal structure of the relationships of common life stressors and psychosocial resources for Canadians 65 years and older (542 men and 835 women). Using structural equation modeling of data collected in the National Population Health Survey in 2004-2005 and 2002-2003, the roles played by socioeconomic conditions, physical health, chronic stress, sense of mastery, and perceived social support in the stress-psychological distress relationship were estimated and compared. Findings revealed that chronic stress was the strongest determinant of the level of psychological distress for both genders; however its effect was higher for men compared to women. Poor physical health played a more important role in determining women's psychological distress compared to men. Higher levels of mastery and perceived social support were associated with lower levels of psychological distress for both men and women. These associations were somewhat stronger for men compared with women. Socio-economic conditions played a minor role in the stress-mental health relationship for both genders.

    The study of systems with sustained energy uptake and dissipation at the scale of the constituent particles is an area of central interest in nonequilibrium statistical physics. Identifying such systems as a distinct category—Active matter—unifies our understanding of autonomous collective movement in the living world and in some surprising inanimate imitations. In this article I present the active matter framework, briefly recall some early work, review our recent results on single-particle and collective behaviour, including experiments on active granular monolayers, and discuss new directions for the future.

    Homework in introductory physics represents an important part of a student's learning experience; therefore choosing the manner in which homework is presented merits investigation. We performed three rounds of clinical trials comparing the effects of mastery-style homework vs traditional-style homework with students in both algebra-based and calculus-based introductory mechanics. Results indicate a benefit from mastery-style over traditional-style homework, principally for weaker students who are less familiar with the material being covered and on questions that are nearer transfer to the study materials.

    I show that a very simple model in the context of Newtonian physics promoted to a first approximation of general relativity can mimic Dark matter and explain most of its intriguing properties. Namely: i) Dark matter is a halo associated to ordinary matter; ii) Dark matter does not interact with ordinary matter nor with itself; iii) Its influence grows with the size of the aggregate of ordinary matter that is considered, and iv) Dark matter influences the propagation of light.

    Engaging in social interaction has, for people with psychiatric disabilities, been shown to enhance well-being and the experience of meaning and to generally prevent the worsening of mental illness. The aim of the study was to investigate how day centre attendees differed from non-attendees regarding different aspects of social interaction and to investigate how occupational factors, including day centre attendance, and previously known predictors were related to social interaction in the study sample as a whole. A total of 93 day centre attendees and 82 non-attendees with psychiatric disabilities were examined regarding social interaction, subjective perception of occupation, activity level, sense of self-mastery and socio-demographic and clinical variables. Data were analysed with non-parametric statistics, mainly logistic regression. Social support was mainly provided by informal caregivers such as family members. The day centre attendees had more social relations but did not experience better quality or closeness in their relationships than non-attendees. Important factors for social interaction were subjective perceptions of daily occupation, being married/cohabiting, self-mastery and severity of psychiatric symptoms. Alternative ways of enhancing social interactions in the community is needed, targeting the group's feeling of satisfaction and value in daily life together with self-mastery. © The Author(s) 2013.

    The fundamentals of endoscopic surgery (FES) program has considerable validity evidence for its use in measuring the knowledge, skills, and abilities required for competency in endoscopy. Beginning in 2018, the American Board of Surgery will require all candidates to have taken and passed the written and performance exams in the FES program. Recent work has shown that the current ACGME/ABS required case volume may not be enough to ensure trainees pass the FES skills exam. The aim of this study was to investigate the feasibility of a simulation-based mastery-learning curriculum delivered on a novel physical simulation platform to prepare trainees to pass the FES manual skills exam. The newly developed endoscopy training system (ETS) was used as the training platform. Seventeen PGY 1 (10) and PGY 2 (7) general surgery residents completed a pre-training assessment consisting of all 5 FES tasks on the GI Mentor II. Subjects then trained to previously determined expert performance benchmarks on each of 5 ETS tasks. Once training benchmarks were reached for all tasks, a post-training assessment was performed with all 5 FES tasks. Two subjects were lost to follow-up and never returned for training or post-training assessment. One additional subject failed to complete any portion of the curriculum, but did return for post-training assessment. The group had minimal endoscopy experience (median 0, range 0-67) and minimal prior simulation experience. Three trainees (17.6%) achieved a passing score on the pre-training FES assessment. Training consisted of an average of 48 ± 26 repetitions on the ETS platform distributed over 5.1 ± 2 training sessions. Seventy-one percent achieved proficiency on all 5 ETS tasks. There was dramatic improvement demonstrated on the mean post-training FES assessment when compared to pre-training (74.0 ± 8 vs. 50.4 ± 16, p assessment (r = 0.57, p = 0.028). Fourteen (100%) subjects who trained to proficiency on at least one ETS task

  16. Maxwell Matters

    CERN Document Server

    Eisenberg, Bob

    2016-01-01

    Charges are everywhere because most atoms are charged. Chemical bonds are formed by electrons with their charge. Charges move and interact according to Maxwell's equations in space and in atoms where the equations of electrodynamics are embedded in Schroedinger's equation as the potential. Maxwell's equations are universal, valid inside atoms and between stars from times much shorter than those of atomic motion (0.1 femtoseconds) to years (32 mega-seconds). Maxwell's equations enforce the conservation of current. Analysis shows that the electric field can take on whatever value is needed to ensure conservation of current. The properties of matter rearrange themselves to satisfy Maxwell's equations and conservation of current. Conservation of current is as universal as Maxwell's equations themselves. Yet equations of electrodynamics find little place in the literature of material physics, chemistry, or biochemistry. Kinetic models of chemistry and Markov treatments of atomic motion are ordinary differential eq...

    Full Text Available One of the purpose of teaching speaking is the students are able to use English as a means of communication based on the context and situation related to their level of vocabulary mastery. So before we are able to communicate well, we should have a large number of words. The objective of this research is to find out whether vocabulary is influential toward English speaking ability. The populations of this research are 190 students of all the fourth semester in the academic year of 2009-2010. Based on the table of Krecjie, a number of samples are 127 students. The sampling technique used is the simple random sampling technique. To collect the data, the researcher requires two tests, vocabulary and speaking tests. This study yields that there is a positive and significant influence between English vocabulary mastery and the students’ speaking ability, it is proved by the value of correlation coefficient 0.764 which is higher than the value of r table (0.176. It means that the rise of the independent variable (the students’ vocabulary mastery will be followed by the rise of the dependent variable (English speaking ability. The effective contribution of the students’ vocabulary mastery toward English speaking ability is 58.6%

    Full Text Available We examined age differences in self-perceptions of five dimensions of mastery motivation and also of competence in American, Chinese, and Hungarian children and teens. Participants included 200 Americans, 1,465 Chinese, and 8,175 Hungarians from 7 to 19 years of age. The Dimensions of Mastery Questionnaire provides comparable data across these different cultures as indicated by very similar factor structures and reasonably good internal consistency reliabilities for the scales. Across all three cultures, there was the expected decline from primary to secondary school in total persistence and the four instrumental mastery motivation scales, except for social persistence with adults in the American sample. Mastery pleasure did not decline in the American and Chinese samples but declined in the Hungarian sample. Self-perceived competence did not decline significantly in the American sample or in the Hungarian sample from age 11 to 17; however, competence self-ratings declined in the Chinese sample. The three cultures were compared at 11 and 16. Although there were some significant differences, small effect sizes indicated that the level of motivation was similar for each culture at each age. The other literature provides clues about why the declines occur in all three cultures and why there are some differences among cultures.

  10. Student Mastery of the Sun-Earth-Moon System in a Flipped Classroom of Pre-service Elementary Education Students

    Science.gov (United States)

    Larsen, Kristine

    2014-01-01

    One of the current trends in pedagogy at all levels(K-college) is the so-called ‘flipped classroom’, in which students prepare for a class meeting through self-study of the material. It is based on a rejection of the classic model of the faculty member as the ‘sage on the stage’ instead, responsibility for learning shifts to the individual student. The faculty member takes on the role of learning facilitator or mentor, and focuses the students’ learning by crafting and administering timely formative assessments (in multiple formats and applied multiple times) that aid both students and the faculty member in tracking the students’ mastery of the learning outcomes. In a flipped, freshman-only, section of SCI 111 Elementary Earth-Physical Sciences (a required introductory science course for pre-service elementary school teachers) the students learned through a combination of individual and group hands-on in-class activities, technology (including PowerPoint presentations and short videos viewed prior to attending class), in-class worksheets, and in-class discussions. Students self-differentiated in how they interacted with the available teaching materials, deciding which activities to spend the most time on based on their individual needs (based on an online quiz taken the night before the class period, and their personal self-confidence with the material). Available in-class activities and worksheets were developed by the faculty member based on student scores on the online quiz as well as personal messages submitted through the course management system the night before the class meeting. While this placed a significant burden on the faculty member in terms of course preparation, it allowed for just-in-time teaching to take place. This poster describes the results of student mastery of content centered on the sun-earth-moon system (specifically seasons, moon phases, and eclipses) as compared to traditional classroom sections.

    2013-04-01

    The purpose of this action research was to increase the mastery level of Form Five Social Science students in Tawau II National Secondary School in the operations of addition, subtraction and multiplication of matrices in Mathematics. A total of 30 students were involved. Preliminary findings through the analysis of pre-test results and questionnaire had identified the main problem faced in which the students felt confused with the application of principles of the operations of matrices when performing these operations. Therefore, an action research was conducted using an intervention programme called "G.P.S Matrices" to overcome the problem. This programme was divided into three phases. 'Gift of Matrices' phase aimed at forming matrix teaching aids. The second and third phases were 'Positioning the Elements of Matrices' and 'Strenghtening the Concept of Matrices'. These two phases were aimed at increasing the level of understanding and memory of the students towards the principles of matrix operations. Besides, this third phase was also aimed at creating an interesting learning environment. A comparison between the results of pre-test and post-test had shown a remarkable improvement in students' performances after implementing the programme. In addition, the analysis of interview findings also indicated a positive feedback on the changes in students' attitude, particularly in the aspect of students' understanding level. Moreover, the level of students' memory also increased following the use of the concrete matrix teaching aids created in phase one. Besides, teachers felt encouraging when conducive learning environment was created through students' presentation activity held in third phase. Furthermore, students were voluntarily involved in these student-centred activities. In conclusion, this research findings showed an increase in the mastery level of students in these three matrix operations and thus the objective of the research had been achieved.

    Full Text Available Whether managers are concerned with financial issues, marketing, or human resource management (HRM, cultural values and practices do matter. The purpose of this article is to understand Norwegian managers’ cultural values within the cross-cultural landscape of her neighbors in the “Scandinavian cluster.” Clearly, subtle but disturbing differences may surface even when representatives from similar cultures work together. As a follow on from the GLOBE project, data based on the GLOBE instrument were collected on culture and communication values in Norway from 710 Norwegian middle managers for this present study. Although the Scandinavian cultures appear ostensibly similar, the results illustrate that research can reveal subtle but important cultural differences in nations that are similar yet dissimilar. All three Scandinavian societies appear intrinsically egalitarian; they appear to value low Power Distance, directness, and consensus in decision making and to promote Gender Egalitarianism. Nevertheless, there are significant differences in the degrees of commitment to these values by each individual Scandinavian partner. These differences need to be understood and appreciated to avoid misunderstandings.

The recommendations of ATEE are based on a balance and sustainable mastery of both the energy demand and the energy offer: 1 - reduction of the demand and improvement of the energy efficiency (reduction of the French energy intensity, consumer information about energy saving and abatement of CO{sub 2} emissions, abatement of energy consumptions in government buildings, allocation of sufficient budgetary means to the French agency of environment and energy mastery (Ademe), implementation of energy mastery programs by energy suppliers, generalization of 'result contracts' by energy service companies and progressive integration of CO{sub 2} emissions, appointment of energy responsible persons in administrations and energy consuming companies, creation of a domestic emission credit market for non-eligible companies, integration of the indirect emissions due to the transports, implementation of the technology procurement purchase method to improve the energy efficiency of common appliances). 2 - mastery of the offer: encouraging cogeneration, revalorization of the repurchase tariffs of the electricity produced from renewable energies, flattening of the administrative, regulatory and contractual obstacles, promotion of the use of renewable heat. The contributions of the 'cogeneration', 'biogas' and 'wood-fuel' associations are given in appendixes. (J.S.)

    We observed the characteristics of white matter fibers and gray matter in multiple sclerosis patients, to identify changes in diffusion tensor imaging fractional anisotropy values following white matter fiber injury. We analyzed the correlation between fractional anisotropy values and changes in whole-brain gray matter volume. The participants included 20 patients with relapsing-remitting multiple sclerosis and 20 healthy volunteers as controls. All subjects underwent head magnetic resonance imaging and diffusion tensor imaging. Our results revealed that fractional anisotropy values decreased and gray matter volumes were reduced in the genu and splenium of corpus callosum, left anterior thalamic radiation, hippocampus, uncinate fasciculus, right corticospinal tract, bilateral cingulate gyri, and inferior longitudinal fasciculus in multiple sclerosis patients. Gray matter volumes were significantly different between the two groups in the right frontal lobe (superior frontal, middle frontal, precentral, and orbital gyri), right parietal lobe (postcentral and inferior parietal gyri), right temporal lobe (caudate nucleus), right occipital lobe (middle occipital gyrus), right insula, right parahippocampal gyrus, and left cingulate gyrus. The voxel sizes of atrophic gray matter positively correlated with fractional anisotropy values in white matter association fibers in the patient group. These findings suggest that white matter fiber bundles are extensively injured in multiple sclerosis patients. The main areas of gray matter atrophy in multiple sclerosis are the frontal lobe, parietal lobe, caudate nucleus, parahippocampal gyrus, and cingulate gyrus. Gray matter atrophy is strongly associated with white matter injury in multiple sclerosis patients, particularly with injury to association fibers.

    At first sight, low-temperature condensed-matter physics and early Universe cosmology seem worlds apart. Yet, in the last few years a remarkable synergy has developed between the two. It has emerged that, in terms of their mathematical description, there are surprisingly close parallels between them. This interplay has been the subject of a very successful European Science Foundation (ESF) programme entitled COSLAB ('Cosmology in the Laboratory') that ran from 2001 to 2006, itself built on an earlier ESF network called TOPDEF ('Topological Defects: Non-equilibrium Field Theory in Particle Physics, Condensed Matter and Cosmology'). The articles presented in this issue of Philosophical Transactions A are based on talks given at the Royal Society Discussion Meeting 'Cosmology meets condensed matter', held on 28 and 29 January 2008. Many of the speakers had participated earlier in the COSLAB programme, but the strength of the field is illustrated by the presence also of quite a few new participants.

  17. Sirius Matters

    2008-01-01

    Since very early times Sirius was a point of attraction in the night sky. It served to synchronize calendars in antiquity and was the subject of many myths and legends, including some modern ones. It was perceived as a red star for more than 400 years, but such reports were relegated to the Mediterranean region. Astronomically, Sirius is a very bright star. This, and its present close distance to us, argues in favor of it being the target of detailed studies of stellar structure and evolution. Its binary nature, with a companion that is one of the more massive white dwarfs, is an additional reason for such studies. This book collects the published information on Sirius in an attempt to derive a coherent picture of how this system came to look as it does.

    2011-01-01

    That language and sexuality are closely connected is one of the enduring themes in human sexuality research. The articles in this special issue of the Journal of Homosexuality explore some of these language-centered insights as they apply to same-sex related desires, identities, and practices and to other dimensions of non-normative sexual experiences. The articles address language use over a range of geographic and social locations. The linguistic practices discussed are diverse, including the language associated with Santería, comments viewers make about gay pornography, homophobic discourse, coming out stories, stories where declarations of sexual identity are tacitly withheld, sexual messages in Black hip hop culture, assessments of urban AIDS ministries, and policies that limit transgender subjects' access to urban space. Taken together, these articles demonstrate that language matters in the everyday experience of sexual sameness and they model some of the approaches that are now being explored in language and sexuality studies.

    Full Text Available Based on the content standard, junior high school students are hoped to master vocabulary about 1000 words, so they can understand the conversation. But it fact, most of the students in junior high school do not master vocabulary well. So, the teacher should be able to choose a good media to help students to increase their vocabulary. In this case, flash card with picture story is two of media that can be used to transfer vocabulary material for the students.   The objective of this research is to find the significant differences of using flash card with picture story in vocabulary, and to find which medium is more effective to use as media in vocabulary. This research was true experiment design. Pre test and post test were use to collect the data. There are two problems of the study, (1 are there any significant differences between flash card with picture story in vocabulary mastery for the seventh grade students in SMP PGRI 2 Margatiga academic years 2013/2014?, (2 which one is more effective media in vocabulary learning process, is it flash card or picture story at seventh grade of SMP PGRI 2 Margatiga, academic years 2013/2014?. As a source of data, the researcher utilized flash card with picture story to teach vocabulary for the students. The media help students to learn vocabulary easier and more interesting to understand the subject, so their vocabulary would increase.   The result of the research, it was found that the mean score of picture story in pre test is 53,86, in treatment is 81, and in post test 85,33. Meanwhile the mean score of the flash card media in pre test 59,33, in treatment is 73,5, and in post test is 80,66. It means that the student’s vocabulary has increased, and there is significant difference of using picture story and flash card in vocabulary instruction, and picture story was more effective to use in vocabulary instruction.

  2. Media matters.

    The impact of the mass media on woman's status was addressed at two 1995 conferences: the Fourth World Conference on Women, held in Beijing, China, and the Congress of the World Association for Christian Communication, held in Puebla, Mexico. The globalization process facilitated by the mass media has served to increase the power of patriarchy, with no advantages to the cause of women's rights. Coverage of popular movements has been suppressed out of deference to male-controlled governments. Coverage of the Beijing Conference highlighted celebrities and personal stories, to the exclusion of the economic and political issues under debate. Television has commodified women, reinforcing their oppression. On the other hand, the alternative media, which tend to be decentralized, democratic, low-cost, and low in technology, are presenting women as subjects rather than objects and deconstructing gender stereotypes. Of concern, however, is the tendency of computer technology to widen the gap between social classes and developed and developing countries. Women must use information networks to disseminate information on women's rights and strengthen the links between women throughout the world.

    From the advent of digital imaging through several decades of studies, the human vision research community systematically focused on perceived image quality and digital artifacts due to resolution, compression, gamma, dynamic range, capture and reproduction noise, blur, etc., to help overcome existing technological challenges and shortcomings. Technological advances made digital images and digital multimedia nearly flawless in quality, and ubiquitous and pervasive in usage, provide us with the exciting but at the same time demanding possibility to turn to the domain of human experience including higher psychological functions, such as cognition, emotion, awareness, social interaction, consciousness and Self. In this paper we will outline the evolution of human centered multidisciplinary studies related to imaging and propose steps and potential foci of future research.

    2016-12-01

    We have developed a novel method to describe human white matter anatomy using an approach that is both intuitive and simple to use, and which automatically extracts white matter tracts from diffusion MRI volumes. Further, our method simplifies the quantification and statistical analysis of white matter tracts on large diffusion MRI databases. This work reflects the careful syntactical definition of major white matter fiber tracts in the human brain based on a neuroanatomist's expert knowledge. The framework is based on a novel query language with a near-to-English textual syntax. This query language makes it possible to construct a dictionary of anatomical definitions that describe white matter tracts. The definitions include adjacent gray and white matter regions, and rules for spatial relations. This novel method makes it possible to automatically label white matter anatomy across subjects. After describing this method, we provide an example of its implementation where we encode anatomical knowledge in human white matter for ten association and 15 projection tracts per hemisphere, along with seven commissural tracts. Importantly, this novel method is comparable in accuracy to manual labeling. Finally, we present results applying this method to create a white matter atlas from 77 healthy subjects, and we use this atlas in a small proof-of-concept study to detect changes in association tracts that characterize schizophrenia.

  20. Learning from input and memory evolution: points of vulnerability on a pathway to mastery in word learning.

    Science.gov (United States)

    Storkel, Holly L

    2015-02-01

    Word learning consists of at least two neurocognitive processes: learning from input during training and memory evolution during gaps between training sessions. Fine-grained analysis of word learning by normal adults provides evidence that learning from input is swift and stable, whereas memory evolution is a point of potential vulnerability on the pathway to mastery. Moreover, success during learning from input is linked to positive outcomes from memory evolution. These two neurocognitive processes can be overlaid on to components of clinical treatment with within-session variables (i.e. dose form and dose) potentially linked to learning from input and between-session variables (i.e. dose frequency) linked to memory evolution. Collecting data at the beginning and end of a treatment session can be used to identify the point of vulnerability in word learning for a given client and the appropriate treatment component can then be adjusted to improve the client's word learning. Two clinical cases are provided to illustrate this approach.

  1. How the Mastery Rubric for Statistical Literacy Can Generate Actionable Evidence about Statistical and Quantitative Learning Outcomes

    Directory of Open Access Journals (Sweden)

    Rochelle E. Tractenberg

    2016-12-01

    Full Text Available Statistical literacy is essential to an informed citizenry; and two emerging trends highlight a growing need for training that achieves this literacy. The first trend is towards “big” data: while automated analyses can exploit massive amounts of data, the interpretation—and possibly more importantly, the replication—of results are challenging without adequate statistical literacy. The second trend is that science and scientific publishing are struggling with insufficient/inappropriate statistical reasoning in writing, reviewing, and editing. This paper describes a model for statistical literacy (SL and its development that can support modern scientific practice. An established curriculum development and evaluation tool—the Mastery Rubric—is integrated with a new, developmental, model of statistical literacy that reflects the complexity of reasoning and habits of mind that scientists need to cultivate in order to recognize, choose, and interpret statistical methods. This developmental model provides actionable evidence, and explicit opportunities for consequential assessment that serves students, instructors, developers/reviewers/accreditors of a curriculum, and institutions. By supporting the enrichment, rather than increasing the amount, of statistical training in the basic and life sciences, this approach supports curriculum development, evaluation, and delivery to promote statistical literacy for students and a collective quantitative proficiency more broadly.

    Happiness is a subjective experience that is an ultimate goal for humans. Psychological studies have shown that subjective happiness can be measured reliably and consists of emotional and cognitive components. However, the neural substrates of subjective happiness remain unclear. To investigate this issue, we used structural magnetic resonance imaging and questionnaires that assessed subjective happiness, the intensity of positive and negative emotional experiences, and purpose in life. We found a positive relationship between the subjective happiness score and gray matter volume in the right precuneus. Moreover, the same region showed an association with the combined positive and negative emotional intensity and purpose in life scores. Our findings suggest that the precuneus mediates subjective happiness by integrating the emotional and cognitive components of happiness.

    2017-12-01

    Full Text Available This paper is a quasi-experimental research. It was aimed to investigate the significant difference on vocabulary achievement between two groups who were taught by using Mind Mapping strategy and those who were taught by using Making Notes strategy. The subjects of this study were the students in class 5B and 5D of An-Nissa Islamic Billingual Elementary School of Semarang. 5B was the experimental group and 5D was the control group. In this research, I gave them a pre-test, treatments, and a post-test. I used the same instrument in the pre-test for both groups. They were asked to answer some questions of vocabulary test. The treatments were given in three meetings. The treatment used in the experimental group was Mind Mapping strategy, while the treatment in the control group was Making Notes strategy. The post-test in both groups were conducted after the treatments by using the same instrument as the pre-test but the position of question numbers were reshuffled. The result of the test was analyzed by using t-test formula to know the difference of the students‘ achievement in vocabulary between two groups. The analysis of the test result showed that the experimental group got better score than the control group. That calculation revealed that the hypothesis 1 (Ha was accepted and the hypothesis 2 (Ho was rejected. Based on the proven hypotheses, I concluded that Mind Mapping strategy is more effective to be implemented in teaching vocabulary than Making Notes strategy.

  6. Evidence for Functional Networks within the Human Brain's White Matter.

    Investigation of the functional macro-scale organization of the human cortex is fundamental in modern neuroscience. Although numerous studies have identified networks of interacting functional modules in the gray-matter, limited research was directed to the functional organization of the white-matter. Recent studies have demonstrated that the white-matter exhibits blood oxygen level-dependent signal fluctuations similar to those of the gray-matter. Here we used these signal fluctuations to investigate whether the white-matter is organized as functional networks by applying a clustering analysis on resting-state functional MRI (RSfMRI) data from white-matter voxels, in 176 subjects (of both sexes). This analysis indicated the existence of 12 symmetrical white-matter functional networks, corresponding to combinations of white-matter tracts identified by diffusion tensor imaging. Six of the networks included interhemispheric commissural bridges traversing the corpus callosum. Signals in white-matter networks correlated with signals from functional gray-matter networks, providing missing knowledge on how these distributed networks communicate across large distances. These findings were replicated in an independent subject group and were corroborated by seed-based analysis in small groups and individual subjects. The identified white-matter functional atlases and analysis codes are available at http://mind.huji.ac.il/white-matter.aspx Our results demonstrate that the white-matter manifests an intrinsic functional organization as interacting networks of functional modules, similarly to the gray-matter, which can be investigated using RSfMRI. The discovery of functional networks within the white-matter may open new avenues of research in cognitive neuroscience and clinical neuropsychiatry.SIGNIFICANCE STATEMENT In recent years, functional MRI (fMRI) has revolutionized all fields of neuroscience, enabling identifications of functional modules and networks in the human

    Early detection of white matter injury in premature newborns can facilitate timely clinical treatments reducing the potential risk of later developmental deficits. It was reported that there were more than 5% premature newborns in British Columbia, Canada, among which 5-10% exhibited major motor deficits and 25-50% exhibited significant developmental and visual deficits. With the advancement of computer assisted detection systems, it is possible to automatically identify white matter injuries, which are found inside the grey matter region of the brain. Atlas registration has been suggested in the literature to distinguish grey matter from the soft tissues inside the skull. However, our subjects are premature newborns delivered at 24 to 32 weeks of gestation. During this period, the grey matter undergoes rapid changes and differs significantly from one to another. Besides, not all detected white spots represent injuries. Additional neighborhood information and expert input are required for verification. In this paper, we propose a white matter feature identification system for premature newborns, which is composed of several steps: (1) Candidate white matter segmentation; (2) Feature extraction from candidates; (3) Validation with data obtained at a later stage on the children; and (4) Feature confirmation for automated detection. The main challenge of this work lies in segmenting white matter injuries from noisy and low resolution data. Our approach integrates image fusion and contrast enhancement together with a fuzzy segmentation technique to achieve promising results. Other applications, such as brain tumor and intra-ventricular haemorrhage detection can also benefit from our approach.

    Telehealth care was developed to provide home-based monitoring and support for patients with chronic disease. The positive effects on physical outcome have been reported; however, more evidence is required concerning the effects on family caregivers and family function for heart failure patients transitioning from the hospital to home. To evaluate the effectiveness of nursing-led transitional care combining discharge plans and telehealth care on family caregiver burden, stress mastery and family function in family caregivers of heart failure patients compared to those receiving traditional discharge planning only. This is a quasi-experimental study design. Sixty-three patients with heart failure were assessed for eligibility and invited to participate in either telehealth care or standard care in a medical centre from May to October 2010. Three families refused to participate in data collection. Thirty families who chose telehealth care after discharge from the hospital to home comprised the experimental group; the others families receiving discharge planning only comprised the comparison group. Telenursing specialist provided the necessary family nursing interventions by 24-h remote monitoring of patients' health condition and counselling by telephone, helping the family caregivers successfully transition from hospital to home. Data on caregiver burden, stress mastery and family function were collected before discharge from the hospital and one month later at home. Effects of group, time, and group×time interaction were analysed using Mixed Model in SPSS (17.0). Family caregivers in both groups had significantly lower burden, higher stress mastery, and better family function at one-month follow-up compared to before discharge. The total score of caregiver burden, stress mastery and family function was significantly improved for the family caregivers in the experimental group compared to the comparison group at posttest. Two subscales of family function

    Doctors' self-perceived mastery of clinical work might have an impact on their career and patient care, in addition to their own health and well-being. The aim of this study is to identify predictors at medical school of perceived mastery later in doctors' careers. A cohort of medical students (n=631) was surveyed in the final year of medical school in 1993/1994 (T1), and 10 (T2) and 20 (T3) years later. Nationwide healthcare institutions. Medical students from all universities in Norway. Perceived mastery of clinical work was measured at T2 and T3. The studied predictors measured at T1 included personality traits, medical school stress, perceived medical recording skills, identification with the role of doctor, hazardous drinking and drinking to cope, in addition to age and gender. Effects were studied using multiple linear regression models. Response rates: T1, 522/631 (83%); T2, 390/522 (75%); and T3, 303/522 (58%). Mean scores at T2 and T3 were 22.3 (SD=4.2) and 24.5 (3.0) (t=8.2, pmedical recording skills (β=0.13; p=0.02; 95% CI 0.02 to 0.24) and drinking to cope (β=-2.45; p=0.001; 95% CI -3.88 to -1.03). Adjusted association at T3 was perceived medical recording skills (β=0.11; p=0.015; 95% CI 0.02 to 0.21). Perceived medical recording skills and role identification were associated with higher perceived mastery. Medical schools should provide experiences, teaching and assessment to enhance students' physician role identification and confidence in their own skills. Drinking to cope was associated with lower perceived mastery, which indicates the importance of acquiring healthier coping strategies in medical school. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    We organize the effective (self)interaction terms for complex scalar dark matter candidates which are either an isosinglet, isodoublet or an isotriplet with respect to the weak interactions. The classification has been performed ordering the operators in inverse powers of the dark matter cutoff...... scale. We assume Lorentz invariance, color and charge neutrality. We also introduce potentially interesting dark matter induced flavor-changing operators. Our general framework allows for model independent investigations of dark matter properties....

Experimental program for the study of properties of dense cold matter for light and heavy ion collisions at initial energy range √sNN~2-3GeV is proposed..

  17. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    Full Text Available The importance of Levinas’ notions of sensibility and subjectivity are evident in the revision of phenomenological method by current phenomenologists such as Jean-Luc Marion and Michel Henry. The criticisms of key tenants of classical phenomenology, intentionality and reduction, are of a particular note. However, there are problems with Levinas’ characterization of subjectivity as essentially sensible. In “Totality and Infinity” and “Otherwise than Being”, Levinas criticizes and recasts a traditional notion of subjectivity, particularly the notion of the subject as the first and foremost rational subject. The subject in Levinas’ works is characterized more by its sensibility and affectedness than by its capacity to reason or affect its world. Levinas ties rationality to economy and suggests an alternative notion of reason that leads to his analysis of the ethical relation as the face-to-face encounter. The ‘origin’ of the social relation is located not in our capacity to know but rather in a sensibility that is diametrically opposed to the reason understood as economy. I argue that the opposition in Levinas’ thought between reason and sensibility is problematic and essentially leads to a self-conflicted subject. In fact, it would seem that violence characterizes the subject’s self-relation and, thus, is also inscribed at the base of the social relation. Rather than overcoming a problematic tendency to dualistic thought in philosophy Levinas merely reverses traditional hierarchies of reason/emotion, subject/object and self/other.

    We discuss several cosmological production mechanisms for nonthermal supermassive dark matter and argue that dark matter may he elementary particles of mass much greater than the weak scale. Searches for dark matter should ma be limited to weakly interacting particles with mass of the order of the weak scale, but should extend into the supermassive range as well.
