  11. Bidirectional grey matter changes after complex motor skill learning

    Directory of Open Access Journals (Sweden)

    Martin eGryga

    2012-05-01

    Full Text Available Long-term motor skill learning has been consistently shown to result in functional as well as structural changes in the adult human brain. However, the effect of short learning periods on brain structure is not well understood. In the present study, subjects performed a sequential pinch force task (SPFT for 20 minutes on 5 consecutive days. Changes in brain structure were evaluated with anatomical MRI scans acquired on the first and last day of motor skill learning. Behaviorally, the SPFT resulted in sequence-specific learning with the trained (right hand. Structural grey matter (GM alterations in left M1, right ventral premotor cortex (PMC and right dorsolateral prefrontal cortex (DLPFC correlated with performance improvements in the SPFT. More specifically we found that subjects with strong sequence-specific performance improvements in the SPFT also had larger increases in GM volume in the respective brain areas. On the other hand, subjects with small behavioral gains either showed no change or even a decrease in GM volume during the time course of learning. Furthermore, cerebellar GM volume before motor skill learning predicted (A individual learning related changes in the SPFT and (B the amount of structural changes in left M1, right ventral PMC and DLPFC. In summary, we provide novel evidence that short-term motor skill learning is associated with learning-related structural brain alterations. Additionally, we showed that practicing a motor skill is not exclusively accompanied by increased GM volume. Instead, bidirectional structural alterations explained the variability of the individual learning success.

  12. Teaching Reference Skills: Does it really Matter?

    Directory of Open Access Journals (Sweden)

    Monika Kavalir

    2010-05-01

    Full Text Available The article discusses the results of a study at the core of which is the question of whether teaching reference skills really matters – i.e. how useful it is to train students to work with dictionaries. To answer this query, two issues are investigated: firstly, how effective the particular methodology developed here is with regard to using thesauri; and secondly, whether it makes a difference if some specific hands-on exercises are included or excluded. By the end of the project, the students felt that thesauri, a previously unknown language tool, would be quite useful for their work in the future; on average, they were planning to use a thesaurus several times a month. The analysis of the student questionnaires and a comparison of lexical variation in the first and second drafts of the essays also showed that the experimental group, which received more practical training, generally found thesauri more useful and, accordingly, used them more than the control group did.

    2015-01-01

    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.

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

    Directory of Open Access Journals (Sweden)

    Patrick Schiffler

    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.

    2017-12-01

    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.

  3. 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

  4. Single-subject grey matter graphs in Alzheimer's disease.

    2013-01-01

    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.

  5. 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.

  6. On indexes and subject matter of “global competitiveness”

    2017-01-01

    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. Based on the definitions’ survey the analysis of the subject matter of global

  7. OntoBrowser: a collaborative tool for curation of ontologies by subject matter experts.

    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.

  13. 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.

    Full Text Available The following academic article is based on a PhD thesis that is currently being completed, titled Education and Qualifications of Elementary School Teachers in the U.S. State of Kansas and Slovenia for teaching in classes with immigrant children. 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.

    Full Text Available It has been stated in Lithuania‘s National School Concept that the primary goal of the education of Lithuania is to secure the best possible comprehensive development of physical, psychological and spiritual human powers, to create conditions for the unfolding of the personal individuality. 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.

    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

    Full Text Available In this paper we will present the results of a pedagogical experiment aimed at studying the level of social skills in university professors. Planning cross subject communications in an academic subject with consideration of the previous and associated knowledge and skills of students in the educational programme formed the basis of the pedagogical experiment. Problems have occurred when university professors are faced with elaborating cross subject communications. It was discovered that the problems professors had were connected to their responsiveness and to the various strategies they applied while working within small groups. We will analyze the results, provide recommendations and show the change in the level of the professors’ social skills during elaboration of  cross subject communications.DOI: http://dx.doi.org/10.12731/2218-7405-2013-8-21

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

    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.

    Aoji, Yurina; Miyai, Nobuyuki

    2016-01-01

    In this study, we investigated the association between subjective school adaptation and life skills in elementary school children with chronic diseases. A cross-sectional sample of children with chronic diseases (n=76), who were being treated as pediatric outpatients and who were in the 4th to 6th grade of public elementary schools, was selected. The subjects completed a self-administered questionnaire that comprised an Adaptation Scale for School Environments on Six Spheres (ASSESS) and life skills scales for self-management and stress coping strategies. Structural equation modeling was conducted to identify the inter-relationship between subjective school adaptation and life skills. Compared with the gender- and schoolyear-matched healthy controls (n=380), a large number of children with chronic diseases had low scores on the measure of interpersonal relationship in school. From the structural equation modeling, the subscales "friend's support" and "victimized relationship" in interpersonal relationship were two of the factors closely related to subjective adaptation of learning as well as school satisfaction in the children with chronic diseases. Furthermore, the "decision-making" and "goal-setting" components of self-management skills demonstrated positive contributions to the adaptation of learning and interpersonal relationship either directly affected by the skills themselves or through the affirmative effects of stress coping strategies. These results suggest that life skills education, focusing on self-management and stress coping strategies along with support to improve interpersonal relationships, is effective in promoting subjective school adaptation and leads to increased school satisfaction in children with chronic diseases.

    Connecting students and teachers in classrooms with science, technology, engineering, and mathematics (STEM) experts provides an invaluable opportunity. Subject matter experts can share exciting science and science-related events as well as help to "translate" science being conducted by professionals. The Expedition Earth and Beyond (EEAB) Program, facilitated by the Astromaterials Research and Exploration Science (ARES) Division at the NASA Johnson Space Center, has been providing virtual access to subject matter experts through classroom connection webinars for the last five years. Each year, the reach of these events has grown considerably, especially over the last nine months. These virtual connections not only help engage students with role models, but are also designed to help teachers address concepts and content standards they are required to teach. These events also enable scientists and subject matter experts to help "translate" current science in an engaging and understandable manner while actively involving classrooms in the journey of science and exploration.

  8. 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.

    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.

    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

    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

    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.

    particular, has experienced a process of changing its formats and expressive content by delivering interactivity, facilitating the expression of subjects by means of different technological devices. So from the perspective of the subject, it is observed that the new technological devices and their new grammars are utilized provided they contribute with meaning to his daily practice and biographical trajectory. Nevertheless, digital inclusion policies have focused only on maximizing access to equipment and digital literacy associated to technology applications and not to the narrative skills of the subjects. It is therefore necessary to generate new concepts that allow new methodological guidelines, in communication and education academic processes, to promote the use of new emerging digital spaces for communicational empowered citizens, that is, from competent to tell (expressive skills to more specifically, tell oneself (as an individual and tell us (collectively. Finally, these will be the expressive spaces of the new television with citizen´s expressions, fostered by converging elements of digital technology.

    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.

  20. '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.

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

    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

    The demanding of assessment in learning process was impact by policy changes. Nowadays, assessment is not only emphasizing knowledge, but also skills and attitudes. However, in reality there are many obstacles in measuring them. This paper aimed to describe how to develop integrated assessment instrument and to verify instruments' validity such as content validity and construct validity. This instrument development used test development model by McIntire. Development process data was acquired based on development test step. Initial product was observed by three peer reviewer and six expert judgments (two subject matter experts, two evaluation experts and two chemistry teachers) to acquire content validity. This research involved 376 first grade students of two Senior High Schools in Bantul Regency to acquire construct validity. Content validity was analyzed used Aiken's formula. The verifying of construct validity was analyzed by exploratory factor analysis using SPSS ver 16.0. The result show that all constructs in integrated assessment instrument are asserted valid according to content validity and construct validity. Therefore, the integrated assessment instrument is suitable for measuring critical thinking abilities and science process skills of senior high school students on electrolyte solution matter.

    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.

    This article investigates the effects that perceived challenges and skills in activities have on the quality of everyday life experience. Based on flow theory it was predicted that quality of daily experience would depend on the challenge experienced and skill required in specific situations, as well as on the balance between challenge and skill. The Experience Sampling Method (ESM) was used on a sample of 208 talented adolescents to measure daily variations in four dimensions of experience (concentration, wish to do the activity, involvement, and happiness) in four contexts (in school, with relatives, with friends, and in solitude). The four dimensions of experience were regressed on the predictors challenges, skills, and their absolute difference expressing the balance/imbalance of challenges and skills. Hierarchical linear modeling, explained in detail herein, was conducted on a 1-week sample of experiences. Findings confirm the prediction of flow theory that the balance of challenges and skills has a positive and independent effect on the quality of experience. Yet some differences of parameter estimates were found between dimensions of experience and between social contexts. These heterogeneities call for a further improvement of the flow model.

    1988-06-01

    The effects of met-enkephalin on the acquisition and retention over 10 days of a perceptual motor skill were investigated. Mice were randomly assigned to either one of two experimental groups (1-mg or 3-mg injections per 1-kg of body weight of met-enkephalin) or one of two control groups (dH2O injections). During the acquisition phase of the study, they were separated into "slow" and "fast" learners on the basis of their skill in negotiating a water maze. The results indicated an inhibitory effect of met-enkephalin in the 3-mg condition in the retention phase of the experiment. Subjects' skill was not implicated as a critical factor in retention of this simple task.

    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.

    The aim was to investigate the efficacy of life skills training on subjective well-being (SWB) among high school females. The population study comprised all female high school of Rafsanjan, Iran, in 2008-2009. Thirty students with the lowest scores according to the Molavi's SWB questionnaire were considered eligible. At the next stage, the required sample of 30 students were selected randomly and divided into two groups of experimental (15 subjects) and control (15 subjects). Then, life skills training sessions were started for the experimental group (eight sessions in a 4-week period). Control group did not receive any intervention. The method of data processing at a descriptive level was through using central tendency indicators, dispersion, frequency, and percentage. Student's t-test was used for analysis of independent variables. The greatest R(2) (0.48) was observed for SWB. The R(2) coefficients for neurosis, stress-depression, vitality, and life determination were 0.27, 0.15, 0.20, and 0.09, respectively. Life skills training showed the greatest effect regarding SWB of the students.

    The aim of this study is to clarify the association between teaching and support skills and the subjective effectiveness of nutritional guidance of registered dietitians working at hospitals. We carried out a questionnaire survey of registered dietitians at hospitals in a Japanese prefecture. The utilization of nutritional teaching skills in nutritional guidance was investigated using a self-produced 36-item questionnaire that was designed to be mainly used for diabetic patients in 4 settings: first guidance, first assessment, contemplation stage, and preparation stage. The support skills were evaluated by Kikuchi's Scale of Social Skills: 18 items. The subjective effectiveness of nutritional guidance was defined by the behavioral change of the patients after nutritional guidance as evaluated by a registered dietitian. There were 75 respondents (response rate 46.6 %). Among the teaching skills, basic skills in an interview were often used, but some related to coaching skills were not in common use in nutritional guidance. Based on the results of principal component analysis, we created a scale for scoring the utilization of nutritional teaching skills in each setting. Multiple linear regression analysis illustrated that high subjective effectiveness of nutritional guidance was associated with high score of teaching skills in the preparation stage setting and high score of support skills. These results show that, in addition to frequent use of nutritional teaching skills, improvement of support skills is also necessary to enhance the effectiveness of nutritional guidance.

    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

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

    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

    It is often difficult to deal with wide-ranging, exciting geoscience topics at introductory level when the background geoscience knowledge of the incoming students is limited. This means that new students can often be confronted by self-contained, subject-based topics (e.g. introductory mineralogy) and fail to see where the bigger pictures may be. Another issue, partly arising from massification and thus increasing diversity of student cohorts but also to changes in UK school education goals, is the realisation that incoming students have difficulties combining lecture note taking, reading and general organisation of paper-based materials into a learning package that can help them write structured essays. They need help with the transfer from school to university education. Two years ago, a curriculum review provided the opportunity to develop a new module that could address these issues. The module deals with current topics. Students attend a series of 8 lectures given by 8 different faculty staff covering topics like The Origin of the Moon, Earthquake Prediction, Mass Extinctions, Snowball Earth, and Geohazards spread over the introductory year. Each lecturer uses whatever delivery style they want (PowerPoint, chalk and talk), but the lecture must be an illustration of the scientific method dealing with evidence, models and uncertainty, and must direct students towards a range of associated reading. The students develop a portfolio with a section for each lecture topic. Each section contains their notes, annotated copies of the reading and a one page (A4) summary of the main points of the topic, derived from both the notes and reading. The students also develop a glossary of geological terms. In addition, the students must attend 6 extra talks given by guest speakers at either the student society meetings or the departmental seminar series. Assessment is by the portfolio (40%) and a final essay paper (60%). The portfolio is collected in at the end of the first

    Mother's formal schooling-even at the primary level-is associated with lower risk of child mortality, although the reasons why remain unclear. This study examines whether mother's reading skills help to explain the association in Nigeria. Using data from the Demographic and Health Survey, the analysis demonstrates that women's reading skills increase linearly with years of primary school; however, many women with several years of formal school are unable to read at all. The results further show that mother's reading skills help to explain the relationship between mother's formal schooling and child mortality, and that mother's reading skills are highly associated with child mortality. The study highlights the need for more data on literacy and for more research on whether and how mother's reading skills lower child mortality in other contexts.

    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.

    2016-01-01

    The aim of the present study was to assess both the direct and indirect effects (i.e., interacting with various job demands) of skill discretion on various psychological outcomes (i.e., emotional exhaustion, intention to leave, affective well-being, and job satisfaction). Data were collected by a self-reported questionnaire in 3 hospitals in Italy. The sample consisted of 522 nurses. Moderated hierarchical regression analyses were employed. The findings highlighted the direct effect of skill discretion on reducing emotional exhaustion, intention to leave, sustaining affective well-being and job satisfaction. As regards interaction effect, the analyses indicated that skill discretion moderates the negative effect of disproportionate patient expectations on all the considered psychological outcomes. On the other hand, skill discretion was found to moderate the effect of cognitive demands on turnover intention as well as the effect of quantitative demands on emotional exhaustion and job satisfaction only in conditions of low job demands. The study revealed some interesting findings, suggesting that skill discretion is not a resource in the pure sense, but that it also has some characteristics of a job demand. The study has relevant practical implications. Particularly, from a job design point of view, the present study suggests that job demands and skill discretion should be balanced carefully in order to sustain job well-being and worker retention.

    Frick, Andrea; Möhring, Wenke

    2015-01-01

    Recent research has shown close links between spatial and mathematical thinking and between spatial abilities and motor skills. However, longitudinal research examining the relations between motor, spatial, and mathematical skills is rare, and the nature of these relations remains unclear. The present study thus investigated the relation between children's motor control and their spatial and proportional reasoning. We measured 6-year-olds' spatial scaling (i.e., the ability to reason about different-sized spaces), their mental transformation skills, and their ability to balance on one leg as an index for motor control. One year later (N = 126), we tested the same children's understanding of proportions. We also assessed several control variables (verbal IQ and socio-economic status) as well as inhibitory control, visuo-spatial and verbal working memory. Stepwise hierarchical regressions showed that, after accounting for effects of control variables, children's balance skills significantly increased the explained variance in their spatial performance and proportional reasoning. Our results suggest specific relations between balance skills and spatial as well as proportional reasoning skills that cannot be explained by general differences in executive functioning or intelligence.

    Background and Objectives: Among the clinical skills needed by all physicians, history taking is one of the most important. The teaching model for peer-assisted history-taking groups investigated in the present study consists of small-group courses in which students practice conducting medical interviews with real patients. The purpose of this pilot study was to investigate the expectations, experiences, and subjective learning progress of participants in peer-assisted history-taking groups. Methods: The 42 medical student participants completed a 4-month, peer-assisted, elective history-taking course, which both began and ended with a subjective assessment of their interview skills by way of a pseudonymized questionnaire. Measures comprised the students' self-assessment of their interview skills, their expectations of, and their experiences with the course and especially with the peer tutors. Results: Medical students' most important motivations in attending peer-assisted history-taking groups were becoming able to complete a structured medical interview, to mitigate difficult interviewing situations, and to address patients' emotional demands appropriately. By the end of the course, students' self-assessment of both their interview skills and management of emotional issues improved significantly. Students especially benefitted from individual feedback regarding interview style and relationship formation, as well as generally accepted and had their expectations met by peer tutors. Conclusions: To meet the important learning objectives of history-taking and management of emotional issues, as well as self-reflection and reflection of student-patient interactions, students in the field greatly appreciate practicing medical interviewing in small, peer-assisted groups with real patients. At the same time, peer tutors are experienced to be helpful and supportive and can help students to overcome inhibitions in making contact with patients.

    The purpose of this study was to (1) examine differences in fundamental movement skills (FMS) proficiency, physical self-concept, and physical activity in children with and without developmental coordination disorder (DCD), and (2) determine the association of FMS proficiency with physical self-concept while considering key confounding factors. Participants included 43 children with DCD and 87 age-matched typically developing (TD) children. FMS proficiency was assessed using the Test of Gross Motor Development - second edition. Physical self-concept and physical activity were assessed using self-report questionnaires. A two-way (group by gender) ANCOVA was used to determine whether between-group differences existed in FMS proficiency, physical self-concept, and physical activity after controlling for age and BMI. Partial correlations and hierarchical multiple regression models were used to examine the relationship between FMS proficiency and physical self-concept. Compared with their TD peers, children with DCD displayed less proficiency in various components of FMS and viewed themselves as being less competent in physical coordination, sporting ability, and physical health. Physical coordination was a significant predictor of ability in object control skills. DCD status and gender were significant predictors of FMS proficiency. Future FMS interventions should target children with DCD and girls, and should emphasize improving object control skills proficiency and physical coordination. Children with DCD tend to have not only lower FMS proficiency than age-matched typically developing children but also lower physical self-concept. Self-perceptions of physical coordination by children with DCD are likely to be valuable contributors to development of object control skills. This may then help to develop their confidence in performing motor skills. Children with DCD need supportive programs that facilitate the development of object control skills. Efficacy of training

    The current study examined whether the arithmetical calculation skills of children, adolescents, and young adults with isolated cleft of the lip and/or palate (iCL/P) differ significantly from unaffected control participants. Comparisons of potential neuropsychological predictors of arithmetical calculation were also conducted to determine whether these variables differ significantly for participants with iCL/P. Participants (N = 176; 93 iCL/P and 83 Control) ranged in age from 7 to 26 years old. A standardized battery of achievement and neuropsychological skills was administered. Between group differences on math achievement was assessed through a univariate analysis of covariance. Relationships between neuropsychological measures and math achievement were analyzed separately for participants with iCL/P and controls through hierarchical linear regressions. Arithmetical calculation was significantly lower for the iCL/P group. Rapid naming, sustained attention, and visual-spatial organization were significant predictors for the iCL/P group; rapid naming was the lone variable that was significantly more predictive of arithmetical calculation for the iCL/P group than for control participants. These results suggest that inefficient verbal label retrieval related to short-term memory (STM) deficits underlie the calculation difficulties of individuals with iCL/P. These findings have implications for approaches to remediation, as well as future research. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  20. Developing resident learning profiles: Do scientific evidence epistemology beliefs, EBM self-efficacy beliefs and EBM skills matter?

    Robert, Nancy J.

    This study investigated resident scientific evidence epistemology beliefs, evidence based medicine (EBM) self-efficacy beliefs, and EBM skills. A convenience sample of fifty-one residents located in six U.S. based residency programs completed an online instrument. Hofer's epistemology survey questionnaire was modified to test responses based on four types of scientific evidence encountered in medical practice (Clinical Trial Phase 1, Clinical Trial Phase 3, Meta-analysis and Qualitative). It was hypothesized that epistemology beliefs would differ based on the type of scientific evidence considered. A principal components analysis produced a two factor solution that was significant across type of scientific evidence suggesting that when evaluating epistemology beliefs context does matter. Factor 1 is related to the certainty of research methods and the certainty of medical conclusions and factor 2 denotes medical justification. For each type of scientific evidence, both factors differed on questions comprising the factor structure with significant differences found for the factor 1 and 2 questions. A justification belief case problem using checklist format was triangulated with the survey results, and as predicted the survey and checklist justification z scores indicated no significant differences, and two new justification themes emerged. Modified versions of Finney and Schraw's statistical self-efficacy and skill instruments produced expected significant EBM score correlations with unexpected results indicating that the number of EBM and statistics courses are not significant for EBM self-efficacy and skill scores. The study results were applied to the construction of a learning profile that provided residents belief and skill feedback specific to individual learning needs. The learning profile design incorporated core values related to 'Believer' populations that focus on art, harmony, tact and diplomacy. Future research recommendations include testing context

    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.

    It is acknowledged in the literature that the physical and cognitive effects of the degenerative neurological condition of multiple sclerosis can impact upon driver safety. The aim of this study was to identify the experiences and needs of people with multiple sclerosis in relation to driver assessment and rehabilitation. Focus group discussions were conducted with people with multiple sclerosis (MS) who were: currently driving; no longer licensed or no longer driving and health professionals. The four themes that emerged from the data were: (1) from self-management to formal assessment - a journey of uncertainty and emotional dilemmas; (2) lost independence with grieving and adjustment by self and family; (3) alternative transport is challenging and unsatisfactory; (4) gaps in information and services exist. The results of this study highlight the need for ongoing support in relation to driving for people with MS, ranging from support for self-management, driving assessment and retraining, and preparation for loss of license. Standardised information needs to be developed and health professionals and licensing authorities require knowledge and skills to ensure driver assessment and rehabilitation processes and resources can better meet the needs of people with MS. There is a need for health professionals to examine driving in people with MS in a holistic manner taking into account the context for the person and the supports available. Self-management and self-assessment emerged as a preferred approach for the participants in this study, indicating that health professionals may need to engage with the process. Tools to support self-assessment of driving abilities for people with MS require further research. Indicators for review and formal assessment of driving abilities is needed. Alternative forms of transport require further investigation and improvement for people with MS.

    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.

    Planning is critical to organizations, especially for those involved in pursuing technologic, scientific, and innovative ventures. Examination of planning processes is particularly important in high-stake and high-risk environments. In the present study, to highlight the significance of planning in the context of long-duration space missions, 11 current and former National Aeronautics and Space Administration (NASA) personnel were interviewed to gain a better understanding of astronaut and Mission Control leadership in preparing for and carrying out space missions. Interviewees focused their responses on perceptions of leadership and thoughts on how long-duration spaceflight leadership should be different from current and short-term spaceflight. Notes from these interviews were content coded and qualitatively analyzed. We found that cognitive planning skills and case-based reasoning were among the variables that were most highly rated for being critical to the success of long-duration space missions. Moreover, qualitative analyses revealed new considerations for long-duration space missions, such as granting greater autonomy to crewmembers and the need for more near-term forecasting. The implications of these findings for understanding the planning processes and necessary characteristics of individuals tasked with planning are discussed.

    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.

    Full Text Available Competency Based Education is a curricular approach that, in addition to the controversy it arises, establishes practices and specific thoughts in schools: its origin from behavioral theories and their connection to the economic field disclose formation objectives that highlight the need of thinking about teaching practices and institutional curricula. These goals linked to projects such as work-oriented education and the propaedeutic cycles reveal the implicit intentions in the education system, where students’ specific characteristics yield to national economic imperatives. This reflection paper seeks to explore and define the ‘conceptual gap’ between an education based on the ideals of trade logic, and one directed to the aesthetic and socio-political formation of the subject, on the basis of legal documents as the Curricular Guidelines, Skill Standards for Spanish Language, Law 39 of 1903, General Law of Education and texts by various educational theorists such as Paulo Freire and Gimeno Sacristan.

    The acquisition of psychomotor skills is a key competence in the practice of dentistry, and innate abilities and motivation have been shown to influence motor performance. However, the explicit integration of these factors into the design of research projects about skill acquisition in dentistry has been limited. Therefore, the purpose of this study was to provide a comprehensive analysis of how dental students' abilities and motivation affected their performance in an operative task. A longitudinal study with two cohorts of dental students was conducted in laboratory classes forming part of an operative technique course. A range of standardised psychometric tests was used to assess different abilities before completing a cavity preparation on Frasaco teeth. This was followed immediately by completion of an Intrinsic Motivation Inventory. Low but statistically significant correlations (P<0.05) were found between dental performance and psychomotor ability (r=0.22), and also dental performance and motivation (r=0.19). A significant difference (P<0.05) was found in the grades obtained for the cavity preparation exercise in one cohort between students with higher levels of psychomotor ability compared with those with lower levels (Tracing scores) (P<0.05). No significant differences in grades obtained for the cavity preparation exercise were found between students with higher and lower levels of motivation. Both innate psychomotor ability and motivation showed only weak positive associations with dental performance on cavity preparation exercises. Our study suggests that student-related factors only provide limited information to explain differences in performance or to be useful as specific predictors of future performance by individuals. © 2011 John Wiley & Sons A/S.

  20. What matters? Assessing and developing inquiry and multivariable reasoning skills in high school chemistry

    Daftedar Abdelhadi, Raghda Mohamed

    Although the Next Generation Science Standards (NGSS) present a detailed set of Science and Engineering Practices, a finer grained representation of the underlying skills is lacking in the standards document. Therefore, it has been reported that teachers are facing challenges deciphering and effectively implementing the standards, especially with regards to the Practices. This analytical study assessed the development of high school chemistry students' (N = 41) inquiry, multivariable causal reasoning skills, and metacognition as a mediator for their development. Inquiry tasks based on concepts of element properties of the periodic table as well as reaction kinetics required students to conduct controlled thought experiments, make inferences, and declare predictions of the level of the outcome variable by coordinating the effects of multiple variables. An embedded mixed methods design was utilized for depth and breadth of understanding. Various sources of data were collected including students' written artifacts, audio recordings of in-depth observational groups and interviews. Data analysis was informed by a conceptual framework formulated around the concepts of coordinating theory and evidence, metacognition, and mental models of multivariable causal reasoning. Results of the study indicated positive change towards conducting controlled experimentation, making valid inferences and justifications. Additionally, significant positive correlation between metastrategic and metacognitive competencies, and sophistication of experimental strategies, signified the central role metacognition played. Finally, lack of consistency in indicating effective variables during the multivariable prediction task pointed towards the fragile mental models of multivariable causal reasoning the students had. Implications for teacher education, science education policy as well as classroom research methods are discussed. Finally, recommendations for developing reform-based chemistry

    Music performance anxiety (MPA), or stage fright in music performance, is a serious problem for many musicians, because performance impairment accompanied by MPA can threaten their career. The present study sought to clarify on how a social-evaluative performance situation affects subjective, autonomic, and motor stress responses in pianists. Measurements of subjective state anxiety, heart rate (HR), sweat rate (SR), and electromyographic (EMG) activity of upper extremity muscles were obtained while 18 skilled pianists performed a solo piano piece(s) of their choice under stressful (competition) and non-stressful (rehearsal) conditions. Participants reported greater anxiety in the competition condition, which confirmed the effectiveness of stress manipulation. The HR and SR considerably increased from the rehearsal to competition condition reflecting the activation of sympathetic division of the autonomic nervous system. Furthermore, participants showed higher levels of the EMG magnitude of proximal muscles (biceps brachii and upper trapezius) and the co-contraction of antagonistic muscles in the forearm (extensor digitorum communis and flexor digitorum superficialis) in the competition condition. Although these responses can be interpreted as integral components of an adaptive biological system that creates a state of motor readiness in an unstable or unpredictable environment, they can adversely influence pianists by disrupting their fine motor control on stage and by increasing the risk of playing-related musculoskeletal disorders.

    To answer the question of whether there is a difference between robotic virtual reality simulator performance assessment and validated human reviewers. Current surgical education relies heavily on simulation. Several assessment tools are available to the trainee, including the actual robotic simulator assessment metrics and the Global Evaluative Assessment of Robotic Skills (GEARS) metrics, both of which have been independently validated. GEARS is a rating scale through which human evaluators can score trainees' performances on 6 domains: depth perception, bimanual dexterity, efficiency, force sensitivity, autonomy, and robotic control. Each domain is scored on a 5-point Likert scale with anchors. We used 2 common robotic simulators, the dV-Trainer (dVT; Mimic Technologies Inc., Seattle, WA) and the da Vinci Skills Simulator (dVSS; Intuitive Surgical, Sunnyvale, CA), to compare the performance metrics of robotic surgical simulators with the GEARS for a basic robotic task on each simulator. A prospective single-blinded randomized study. A surgical education and training center. Surgeons and surgeons in training. Demographic information was collected including sex, age, level of training, specialty, and previous surgical and simulator experience. Subjects performed 2 trials of ring and rail 1 (RR1) on each of the 2 simulators (dVSS and dVT) after undergoing randomization and warm-up exercises. The second RR1 trial simulator performance was recorded, and the deidentified videos were sent to human reviewers using GEARS. Eight different simulator assessment metrics were identified and paired with a similar performance metric in the GEARS tool. The GEARS evaluation scores and simulator assessment scores were paired and a Spearman rho calculated for their level of correlation. Seventy-four subjects were enrolled in this randomized study with 9 subjects excluded for missing or incomplete data. There was a strong correlation between the GEARS score and the simulator metric

    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.

    Full Text Available Although studies have shown that self-control skills (SCSs are positively linked to both personal and interpersonal outcomes in adolescent students, studies on the putative mechanisms underlying this relationship are scarce. Drawing on Self-Determination Theory and previous studies, we theorized that the association between students’ SCSs and their subjective well-being (SWB in school may be mediated by students’ perceived satisfaction of their basic psychological needs for competence, relatedness, and autonomy. The sample consisted of 1576 Israeli adolescent students (54% girls in grades 10–12 (mean age 16 enrolled in 20 schools. A mediation model was tested with structural equation modeling and a robust bootstrap method for testing indirect effects, controlling for school-level variance. The findings supported the hypothesized model and a post hoc multi-group comparison analysis yielded gender invariance in the model. The findings suggest that both girls and boys with high SCSs may perceive themselves as having greater needs satisfaction in school and consequently higher school-related SWB. Implications for policy and practice are discussed.

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

    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.

  11. 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.

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

    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.

    Recently we found that modulation depth of beta power during movement increases with practice over sensory-motor areas in normal subjects but not in patients with Parkinson's disease (PD). As such changes might reflect use-dependent modifications, we concluded that reduction of beta enhancement in PD represents saturation of cortical plasticity. A few questions remained open: What is the relation between these EEG changes and retention of motor skills? Would a second task exposure restore beta modulation enhancement in PD? Do practice-induced increases of beta modulation occur within each block? We thus recorded EEG in patients with PD and age-matched controls in two consecutive days during a 40-min reaching task divided in fifteen blocks of 56 movements each. The results confirmed that, with practice, beta modulation depth over the contralateral sensory-motor area significantly increased across blocks in controls but not in PD, while performance improved in both groups without significant correlations between behavioral and EEG data. The same changes were seen the following day in both groups. Also, beta modulation increased within each block with similar values in both groups and such increases were partially transferred to the successive block in controls, but not in PD. Retention of performance improvement was present in the controls but not in the patients and correlated with the increase in day 1 modulation depth. Therefore, the lack of practice-related increase beta modulation in PD is likely due to deficient potentiation mechanisms that permit between-block saving of beta power enhancement and trigger mechanisms of memory formation.

    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.

    The present study reappraised the relationship between hemispheric specialization strength and cognitive skills in a sample of 297 individuals including 153 left-handers. It additionally assessed the interaction with manual laterality factors, such as handedness, asymmetry of hand motor skills, and familial sinistrality. A Hemispheric Functional Lateralization Index (HFLI) for language was derived from fMRI. Through mixture Gaussian modeling, three types of language hemispheric lateralization were defined: typical (left hemisphere dominance with clear positive HFLI), ambilateral (no dominant hemisphere with HFLI values close to 0), and strongly-atypical (right-hemisphere dominance with clear negative HFLI values). Three cognitive scores were derived from 12 tests covering various aspects of verbal and spatial cognition. Compared to both typical and strongly-atypical participants, those ambilateral for language production had lower performances in verbal and non-verbal domains, indicating that hemispheric specialization and cognitive skills are related in adults. Furthermore, this relationship was independent from handedness and asymmetry for motor skills, as no interaction was observed between these factors. On the other hand, the relationship between familial sinistrality and cognitive skills tended to differ according to language lateralization type. In contrast to previous reports in children, in the present adult population, we found no linear correlation between HFLI and cognitive skills, regardless of lateralization type.

  6. 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

    The well-known gap between guidelines and behaviour in clinical practice calls for effective behaviour change interventions. One example showing this gap is physiotherapists' insufficient assessment of psychosocial prognostic factors in back pain (i.e., yellow flags). The present study aimed to evaluate an educational model by performing a tailored skills training intervention for caregivers and studying changes over time in physiotherapists' assessment of prognostic factors in telephone consultations. A quasi-experimental single-subject design over 36 weeks was used, with repeated measurements during baseline, intervention, and postintervention phases. Four physiotherapists in primary health care audiorecorded a total of 63 consultations with patients. The tailored intervention included individual goal setting, skills training, and feedback on performance. The primary outcome was the number of assessed prognostic factors (0-10). Changes were seen in all four participants. The amount of assessed prognostic factors increased from between 0 and 2 at baseline to between 6 and 10 at postintervention. Time spent on assessment of psychosocial factors increased, and time spent on discussions about biomedical pain symptoms decreased. Knowledge and biopsychosocial attitudes toward back pain were congruent with guidelines at inclusion and did not change markedly during the intervention. Self-efficacy for assessment of cognitive and emotional prognostic factors increased during the study phases. The results suggest that a tailored skills training intervention using behaviour change techniques, such as individual goal setting, skills training, and feedback on performance, is effective in producing change in specific clinical behaviours in physiotherapists.

    The purpose of this study was to assess the effect of a motor-based, social skills intervention for two adolescents with high-functioning autism (HFA) using single-subject design. A description of the intervention is provided as a first step in the manualization process. The intervention was provided as a 7-week after-school program, once weekly to the paired participants. Intervention consisted of role-play methods in which motor behaviours were linked with their cognitive and emotional meanings. Baseline, intervention and 3-month probe data collection periods were carried out and then compared using visual inspection of graphed data, paired t-tests and a three-standard-deviation-band approach. Both participants displayed a statistically significant increase in targeted social skills behaviours from baseline to intervention and maintained this level at a 3-month post-intervention probe. These single-subject design cases illustrate that motor-based, social skills interventions may be effective for adolescents with HFA and warrant further testing.

    Full Text Available INTRODUCTIONInterpersonal skills are becoming more and more a necessity in the medical profession. The expectation from health care professionals is beyond just knowledge of the medical facts. To practice medicine effectively, doctors need to develop interpersonal skills in communication, leadership, management, teaching and time management. All of these are vital tools and are becoming increasingly essential subjects in teaching both undergraduate students and postgraduate doctors. However, a degree of self-motivation and personal initiative is needed to develop these skills. In this article, I will give an overview on interpersonal skills and will be follow this by a series of articles, in future issues, dealing with these skills.

    2004-09-30

    A continuous and structured training in communication skills for medical students still has a comparatively low priority in the curriculum of Swedish medical schools. A recent American study has demonstrated the value of incorporating such training programs during the early phase of medical studies. The effect of this reported intervention program was evaluated with objective structured clinical examination (OSCE). Significantly higher satisfaction in the medical encounter was documented among patients who met students trained in patient centeredness than among those who met students randomised to a control group. Thus, communication training for medical students improves specific competencies known to affect outcome of care. We report our experience with a similar model of a communication-training program during the first four semesters, with examination at the end of the program, which has been part of the pre-clinical curriculum since 1998 at the Karolinska Institute in Stockholm, Sweden.

    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.

    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.

    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.

    Full Text Available Clinical and experimental data have implicated the posterior superior temporal gyrus as an important cortical region in the processing of socially relevant stimuli such as gaze following, eye direction, and head orientation. Gaze following and responding to different socio-communicative signals is an important and highly adaptive skill in primates, including humans. Here, we examined whether individual differences in responding to socio-communicative cues was associated with variation in either grey matter volume and asymmetry in a sample of chimpanzees. MRI scans and behavioral data on receptive joint attention (RJA was obtained from a sample of 191 chimpanzees. We found that chimpanzees that performed poorly on the RJA task had more rightward asymmetries in the posterior but not anterior superior temporal gyrus. We further found that middle-aged and elderly chimpanzee performed more poorly on the RJA task and had significantly less grey matter than young-adult and sub-adult chimpanzees. The results are consistent with previous studies implicating the posterior temporal gyrus in the processing of socially relevant information.

In phase 1 of the study, novice learners and expert surgeons attempted a visual-monitoring task under two conditions: single-task (monitoring a virtual patient's heart-rate) and dual-task (tying surgical knots on a bench-top simulator while monitoring the virtual patient's heart-rate). Novices demonstrated higher mental effort and inferior secondary-task performance on the dual-task compared to experts (RRT 1.76 vs. 0.73, p = 0.012; SDR 0.27 vs. 0.97, p instructional design research are discussed.

Therefore, this study aims at examining whether lecturing skills of faculty could predict their PBL tutoring skills. Methods: This study included evaluation of faculty (n=69 who participated in both tutoring and lecturing within particular PBL units at the College of Medicine and Medical Sciences (CMMS, Arabian Gulf University, Bahrain. Each faculty was evaluated by medical students (n=45±8 for lecturing and 8±2 for PBL tutoring using structured evaluation forms based on a Likert-type scale (poor to excellent. The prediction of tutoring skills using lecturing skills was statistically analyzed using stepwise linear regression. Results: Among the parameters used to judge lecturing skills, the most important predictor for tutoring skills was subject matter mastery in the lecture by explaining difficult concepts and responding effectively to students' questions. Subject matter mastery in the lecture positively predicted five tutoring skills and accounted for 25% of the variance in overall effectiveness of the PBL tutors (F=22.39, P=0.000. Other important predictors for tutoring skills were providing a relaxed class atmosphere and effective use of audiovisual aids in the lecture. Conclusion: Predicting the tutoring skills based on lecturing skills could have implications for recruiting tutors in PBL medical programs and for tutor training initiatives.

    The ability to predict learning performance from brain imaging data has implications for selecting individuals for training or rehabilitation interventions. Here, we used structural MRI to test whether baseline variations in gray matter (GM) volume correlated with subsequent performance after a long-term training of a complex whole-body task. 44 naïve participants were scanned before undertaking daily juggling practice for 6weeks, following either a high intensity or a low intensity training regime. To assess performance across the training period participants' practice sessions were filmed. Greater GM volume in medial occipito-parietal areas at baseline correlated with steeper learning slopes. We also tested whether practice time or performance outcomes modulated the degree of structural brain change detected between the baseline scan and additional scans performed immediately after training and following a further 4weeks without training. Participants with better performance had higher increases in GM volume during the period following training (i.e., between scans 2 and 3) in dorsal parietal cortex and M1. When contrasting brain changes between the practice intensity groups, we did not find any straightforward effects of practice time though practice modulated the relationship between performance and GM volume change in dorsolateral prefrontal cortex. These results suggest that practice time and performance modulate the degree of structural brain change evoked by long-term training regimes. Copyright © 2014. Published by Elsevier Inc.

    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

    Full Text Available The impact science sessions for trainee science teachers have on 11-14 year olds’ learning of science was assessed using questionnaires and a “Video-Interview (trainee –Interview (pupils” (V-I-I technique devised for this study. 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.

  11. A tale of three blind men on the proper subject matter of clinical science and practice: commentary on Plaud's behaviorism vs. Ilardi and Feldman's cognitive neuroscience.

    2001-09-01

    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.

    Full Text Available The article offers a practical approach to the skills a present-day translator needs in order to create high-quality translations. Although a lot of theories can be found regarding the skills of a translator, it is worth checking the reality, which is the primary aim of this article. After a short introduction about the standard skills, we look into the subtitling of an episode from a TV series. Our presupposition is that a subtitler has to combine all sorts of information from different fields effectively in order to maintain quality, including general and specific knowledge of the subject matter. Furthermore, the particular environment of subtitling may contain certain pitfalls, such as the technical know-how. layout, and constraints deriving from the nature of subtitling. We can draw the conclusion that a well-prepared translator can successfully handle the technical challenges of multimedia translation of whatsoever type.

  18. Gray and white matter changes in subjective cognitive impairment, amnestic mild cognitive impairment and Alzheimer's disease: a voxel-based analysis study.

    Directory of Open Access Journals (Sweden)

    Kuniaki Kiuchi

    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.

    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.

    Park, Jungjun; Lombardino, Linda J; Ritter, Michaela

    2013-01-01

    The investigators measured 7 literacy skills in a group of 21 school-age children with mild to moderate sensorineural hearing loss (MSNH group), and compared the scores to those of 2 age-matched groups: children with dyslexia (DYS group) and, as a control, typically developing hearing children (CA group). The MSNH group performed consistently below the CA group but better than the DYS group, an indication that differences in the groups' phonological processing profiles might be an important discriminating feature. Interestingly, the MSNH group showed a selective impairment in word reading accuracy only, whereas their reading rate was relatively unaffected. Children with MSNH who show weak phonological awareness skills seem to compensate by relying on orthographic recognition associated with rapid naming ability. To determine which children with MSNH are at high risk for depressed reading achievement, testing across a widerange of literacy skills should be considered.

    2009-01-01

    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.

    Heckman, James J; Kautz, Tim

    2012-08-01

    This paper summarizes recent evidence on what achievement tests measure; how achievement tests relate to other measures of "cognitive ability" like IQ and grades; the important skills that achievement tests miss or mismeasure, and how much these skills matter in life. Achievement tests miss, or perhaps more accurately, do not adequately capture, soft skills-personality traits, goals, motivations, and preferences that are valued in the labor market, in school, and in many other domains. The larger message of this paper is that soft skills predict success in life, that they causally produce that success, and that programs that enhance soft skills have an important place in an effective portfolio of public policies.

    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.

Females with ASD may have more difficulty developing meaningful friendships than males, as the social climate can be more complex (Archer, Coyne, Personality and Social Psychology Review 9(3):212-230, 2005). This study examined whether treatment response among females differed from males. One hundred and seventy-seven adolescents and young adults with ASD (N = 177) participated in this study. When analyzed by group, no significant differences by gender emerged: PEERS ® knowledge (TASSK/TYASSK, p = .494), direct interactions (QSQ, p = .762), or social responsiveness (SRS, p = .689; SSIS-RS, p = .482). Thus, females and males with ASD respond similarly to the PEERS ® intervention.

    Full Text Available The goal of this study is to improve high school chemistry teacher’s competency in terms of classroom instruction. This goal is achieved through the workshop and continuous assistance activities that enable teachers to improve their knowledge and skills in developing learning scenarios that reflect scientific methods (brain-based learning in the classroom instruction. The effect of teachers’ competence improvement was measured by a survey of student’s perception on the classroom teaching-learning process, using Likert-scale questionnaire. The first poll was conducted before the program was started, and the second one was after the program completion. The first observation shows that only 18% of students perceive that the chemistry learning process in the classroom are “good,” while the rest (82% say that it is “fair”. However, the second poll shows that there are 45% of students who perceive that the learning process is “good”; interestingly, there are 35%, and 20% of respondents say “excellent” and “fair,” respectively. Furthermore, data analyses using chi-square test conclude that the continuous teacher assistance activity significantly improves teachers’ competencies.

    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

  17. 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.

    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 Students’ perceptions of difficulties in speaking on professional issues are in the focus of the present article. It is generally assumed that the skill of speaking a foreign language is very difficult to master, while speaking on professional topics involves such difficulties as the usage of specific vocabulary and ability to deal with listeners’ oncoming arguments. The aims of the current research are to investigate learners’ attitudes to the level of difficulty in speaking activi - ties on a subject matter at university and apply an innovative approach to improving their speaking skills. The methodology applied was focused on guided individual learning (GIL, with gradually increasing amount of spontaneity in public talks on the subject matter, starting with prepared short talks on an ESP issue leading to group discussions; moving on to Power Point presentations, involving spontaneous deviations from the subject and followed by question time; further, adding some complex subject matter, such as a discussion on a problematic professional subject suggested by learning materials; and, eventually, speaking impromptu on an issue, with a high level of control of one’s speaking skills. The research method of the learners’ attitudes employed the survey on learner attitudes to four different speaking activities in the classroom, which included short talks, Power Point Presentations, discussions and speaking impromptu. The questionnaire was administered to students of two different specializations by the end of the semester. The respondents were students who studied Psychology and Social Work at the Faculty of Social Policy, at Mykolas Romeris University in Vilnius, Lithuania. The respondents were asked to indicate the degree of difficulty they had with the various speaking activities on the Likert’s scale ranging from “very difficult” (1 to “very easy” (5. The results indicated that perceptions of difficulties to developing speaking

  20. Vestibular loss and balance training cause similar changes in human cerebral white matter fractional anisotropy.

    Directory of Open Access Journals (Sweden)

    Nadine Hummel

    Full Text Available Patients with bilateral vestibular loss suffer from severe balance deficits during normal everyday movements. Ballet dancers, figure skaters, or slackliners, in contrast, are extraordinarily well trained in maintaining balance for the extreme balance situations that they are exposed to. Both training and disease can lead to changes in the diffusion properties of white matter that are related to skill level or disease progression respectively. In this study, we used diffusion tensor imaging (DTI to compare white matter diffusivity between these two study groups and their age- and sex-matched controls. We found that vestibular patients and balance-trained subjects show a reduction of fractional anisotropy in similar white matter tracts, due to a relative increase in radial diffusivity (perpendicular to the main diffusion direction. Reduced fractional anisotropy was not only found in sensory and motor areas, but in a widespread network including long-range connections, limbic and association pathways. The reduced fractional anisotropy did not correlate with any cognitive, disease-related or skill-related factors. The similarity in FA between the two study groups, together with the absence of a relationship between skill or disease factors and white matter changes, suggests a common mechanism for these white matter differences. We propose that both study groups must exert increased effort to meet their respective usual balance requirements. Since balance training has been shown to effectively reduce the symptoms of vestibular failure, the changes in white matter shown here may represent a neuronal mechanism for rehabilitation.

    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.

    2013-07-10

    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.

    Full Text Available Illicit drugs affect the central nervous system by introducing alterations in cognitive, attention and memory functions. AIM: this paper aims to characterize the auditory selective attention skills of subjects with history of illicit drug use and check whether the amount of time for which these subjects took drugs impacts the severity of the encountered alterations. MATERIALS AND METHOD: this is a cohort, cross-sectional retrospective study. Nineteen male subjects with history of drug use and ages ranging between 16 and 47 years were analyzed. Statistical test: 'Mann-Whitney'. PROCEDURE: initial interview, ENT examination, audiological examination, auditory processing assessment - Staggered Spondaic Word Test - SSW. RESULTS: extremely significant statistical differences were found in the number of errors found in the four listening conditions when control and case group findings were compared. However, when case group subject findings were compared, no statistically significant difference was found. CONCLUSION: the used auditory processing tests - SSW - were sensitive enough to capture and assist in the diagnosis of alterations introduced by the deleterious impact of drug use upon the CNS. The time for which subjects used drugs is not a determining factor on alteration severity.Drogas ilícitas afetam o sistema nervoso central causando alterações nas funções cognitivas, de atenção e memória.

    Full Text Available Adaptive skills are defined as a collection of conceptual, social and practical skills that are learned by people in order to function in their everyday lives. They include an individual's ability to adapt to and manage her or his surroundings to effectively function and meet social or community expectations. Good adaptive skills promote individual's independence in different environments, whereas poorly developed adaptive skills are connected to individual's dependency and with greater need for control and help with everyday tasks. Assessment of adaptive skills is often connected to assessment of intellectual disability, due to the reason that the diagnosis of intellectual disability includes lower levels of achievements on standardized tests of intellectual abilities as well as important deficits in adaptive skills. Assessment of adaptive behavior is a part of standard assessment battery with children and adults with different problems, disorders or disabilities that affect their everyday functioning. This contribution also presents psychometric tools most regularly used for assessment of adaptive skills and characteristics of adaptive skills with individual clinical groups.

    This is an encore presentation of what was presented at the 2012 AGU International Conference. It was entitled: 'ASSESSING CORE COMPETENCIES.' The poster presentation, however, has been redesigned and reorganized with new, revised perspectives. The importance of ASSESSMENT principles has been emphasized. Catherine Palomba and Trudy Banta offer the following definition of assessment, adapted from one provided by Marchese in 1987. Assessment is the systematic collection, review, and use of information about educational programs undertaken for the purpose of improving student learning and development. (Palomba and Banta 1999). Educational institutions are committing substantial resources to the establishment of dedicated technology-based laboratories, so that they will be able to accommodate and fulfill students' desire to master certain of these specific skills. This type of technology-based instruction may raise some fundamental questions about the core competencies of the student learner. Some of the most important questions are : 1. Is the utilization of these fast high-powered computers and user-friendly software programs creating a totally non-challenging instructional environment for the student learner ? 2. Can technology itself all too easily overshadow the learning outcomes intended ? 3. Are the educational institutions simply training students how to use technology rather than educating them in the appropriate field ? 4. Are we still teaching content-driven courses and analysis oriented subject matter ? 5. Are these sophisticated modern era technologies contributing to a decline in the Critical Thinking Capabilities of the 21st century technology-savvy students ? The author tries to focus on technology as a tool and not on the technology itself. He further argues that students must demonstrate that they have the have the ability to think critically before they make an attempt to use technology in a chosen application-specific environment.

    2017-11-01

    The following article is about the problem of insufficient number of drawing and painting lessons delivered in the process of architectural education. There is a comparison between the education of successful architects of the past and modern times. The author stands for the importance of creative subjects being the essential part of development and education of future architects. Skills achieved during the study of creative subjects will be used not only as a mean of self-expression but as an instrument in the toolkit of a professional. Sergei Tchoban was taken as an example of a successful architect for whom the knowledge of a man-made drawing is very important. He arranges the contests of architectural drawings for students promoting creative development in this way. Nowadays, students tend to use computer programs to make architectural projects losing their individual approach. The creative process becomes a matter of scissors and paste being just a copy of something that already exists. The solution of the problem is the reconsideration of the department’s curriculum and adding extra hours for creative subjects.

    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.

    Efforts to reduce adverse event rates in healthcare have revealed the importance of identifying the essential non-technical (cognitive and social) skills for safe and effective performance. Previous research on non-technical skills for operating theatre staff has concentrated on doctors rather than nursing professionals. The aim of the study was to identify the critical non-technical skills that are essential for safe and effective performance as an operating theatre scrub nurse. Experienced scrub nurses (n = 25) and consultant surgeons (n = 9) from four Scottish hospitals were interviewed using a semi-structured format. The protocols were designed to identify the main social and cognitive skills required by scrub nurses. Interviews were digitally recorded, transcribed verbatim and independently coded to extract behaviours in order to produce a list of the main non-technical skills for safe and effective scrub nurse performance. The non-technical skills of situation awareness, communication, teamwork, task management and coping with stress were identified as key to successful scrub nurse task performance. Component sets of behaviours for each of these categories were also noted. The interviews with subject matter experts from scrub nursing and surgery produced preliminary evidence that situation awareness, communication, teamwork and coping with stress are the principal non-technical skills required for effective performance as a scrub nurse.

    Students need to be equipped with the 21st century skills/capabilities to ensure their competitiveness in the knowledge era. So, it is imperative that education at school should be changed in order to fulfill the need. However, there is not any specified approach on how to educate young students for the 21st century capabilities. Regardless the impediment for ts exist, we need to construct an innovative instruction that can develop the students' 21st century skills by incorporating the skills needed, based on contemporary theory of learning, necessary context of learning and appropriate assessment in a chemistry subject matter. This paper discuss the feasible skills to be promoted through chemistry course. Those skills/capabilities are scientific literacy, higher order thinking, communicationand collaboration and curiosity. The promoted are called the 21st century scientific literacy skills in which it emphasis on scientific literacy and embedded the other 21st century skills into the innovative chemistry instruction. The elements involve in the instruction such as inquiry and constructivist approach, nature of science, contemporary/socioscientific issues, critical thinking (higher order thinking).

    School health educators have devoted much attention to cigarette smoking. Recent years have seen the testing of interventions to prevent smoking. To date, controlled studies have not evaluated the added value of skills methods for preventing smoking. This article describes such an evaluation with sixth-grade students from two schools. Subjects were pretested and randomly assigned to receive conventional health education methods or to receive skills intervention. Both conditions included films, peer testimonials, discussions, and homework. Health education condition subjects additionally participated in oral quizzes, games, and debates. Skills condition subjects additionally learned problem-solving, self-instruction, and interpersonal communication methods. At postintervention, skills condition subjects, more than health education condition subjects, had better scores on measures of smoking-related knowledge, attitudes, and intentions. In addition, reported cigarette use, validated by biochemical data collection, was lower in the skills condition than in the health education condition at all postintervention measurements, including a 24-month follow-up. The article discusses the strengths, limits, and implications of the study for other smoking prevention efforts in schools.

    Writing teaching materials is one of the generic pedagogical skills. Teachers and pre-service teachers should be trained to have the skills of writing teaching materials. This study examines the factors that influence the skills of writing in the disciplines among pre-service physics teachers. This study in particular aims to contribute to the development of science writing in the disciplines and to the organization of workshops on writing teaching materials for pre-service teachers. The problems of this research are formulated in the question of what are the factors that influence the skills of pre-service physics teachers in writing teaching materials. The research adopted mixed methods with embedded experimental design. The research subjects were 18 students enrolled in the school physics course. The instruments used consisted of conceptual understanding tests, learning strategy questionnaire, tests of the multiple representation skills, and one-on-one semi- structured interview. Results of data analysis show that the ability and skills of writing physics teaching materials of the pre- service physics teachers are determined by the factors of conceptual understanding of the subject matter with a contribution of 20%, the skills of making multiple representations of concepts with a contribution of 9.8% and students' self-regulation and learning strategy with a contribution of 33.5%. There are other factors that have not been investigated in this study; therefore, it is recommended that future research conduct further investigation on other factors that influence pre-service teachers' skills in writing physics teaching materials.

    Dual-task methodology often directs participants' attention towards a gross motor skill involved in the execution of a skill, but researchers have not investigated the comparative effects of attention on fine motor skill tasks. Furthermore, there is limited information about participants' subjective perception of workload with respect to task performance. To examine this, the current study administered the NASA-Task Load Index following a simulated shooting dual-task. The task required participants to stand 15 feet from a projector screen which depicted virtual targets and fire a modified Glock 17 handgun equipped with an infrared laser. Participants performed the primary shooting task alone (control), or were also instructed to focus their attention on a gross motor skill relevant to task execution (gross skill-focused) and a fine motor skill relevant to task execution (fine skill-focused). Results revealed that workload was significantly greater during the fine skill-focused task for both skill levels, but performance was only affected for the lesser-skilled participants. Shooting performance for the lesser-skilled participants was greater during the gross skill-focused condition compared to the fine skill-focused condition. Correlational analyses also demonstrated a significant negative relationship between shooting performance and workload during the gross skill-focused task for the higher-skilled participants. A discussion of the relationship between skill type, workload, skill level, and performance in dual-task paradigms is presented. Copyright © 2015 Elsevier B.V. All rights reserved.

    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...

    Incident reporting and fieldwork in operating rooms have shown that some of the errors that arise in anaesthesia relate to inadequate use of non-technical skills. To provide a tool for training and feedback on nurse anaesthetists' non-technical skills, this study aimed to adapt the Anaesthetists' Non-Technical Skills (ANTS) as a behavioural marker system for the formative assessment of nurse anaesthetists' non-technical skills in the operating room. A qualitative approach with focus group interviews was used to identify the non-technical skills of nurse anaesthetists in the operating room. The interview data were transcribed verbatim. Directed content analysis was used to code and sort data deductively into the ANTS categories: task management, team working, situation awareness and decision making. The prototype named Nurse Anaesthetists' Non-Technical Skills (N-ANTS) was presented and discussed in a group of subject matter experts to ensure face validity. The N-ANTS system consists of the same four categories as ANTS and 15 underlying elements. Three to five good and poor behavioural markers for each element were identified. The headings and definitions of the categories and elements were adjusted to encompass the behavioural markers in N-ANTS. The differences that emerged mainly reflected statements regarding the establishment of role, competence, and task delegation. A behavioural marker system, N-ANTS, for nurse anaesthetists was adapted from a behavioural marker system, ANTS, for anaesthesiologists. © 2014 The Acta Anaesthesiologica Scandinavica Foundation.

    The current trend in the education is focused on skills that are cross-subject and have a great importance for the pupil future life. Pupils should acquire different types of skills during their education to be prepared for future careers and life in the 21st century. Physics as a subject offers many opportunities for pupils' skills development. One of the skills that are expected to be developed in physics and also in other sciences is making predictions. The prediction, in the meaning of the argument about what may happen in the future, is an integral part of the empirical cognition, in which students confront existing knowledge and experience with new, hitherto unknown and surprising phenomena. The extent of the skill is the formulation of hypotheses, which is required in the upper secondary physics education. In the contribution, the prediction skill is specified and its eventual levels are classified. Authors focus on the tools for skill level determination based on the analysis of pupils` worksheets. Worksheets are the part of the educational activities conducted within the Inquiry Science Laboratory Steelpark. Based on the formulation of pupils' prediction the pupils thinking can be seen and their understanding of the topic, as well as preconceptions and misconceptions.

    Full Text Available Abstract Background Non-technical skills are seen as an important contributor to reducing adverse events and improving medical management in healthcare teams. Previous research on the effectiveness of teams has suggested that shared mental models facilitate coordination and team performance. The purpose of the study was to investigate whether demonstrated teamwork skills and behaviour indicating shared mental models would be associated with observed improved medical management in trauma team simulations. Methods Revised versions of the 'Anesthetists' Non-Technical Skills Behavioural marker system' and 'Anti-Air Teamwork Observation Measure' were field tested in moment-to-moment observation of 27 trauma team simulations in Norwegian hospitals. Independent subject matter experts rated medical management in the teams. An independent group design was used to explore differences in teamwork skills between higher-performing and lower-performing teams. Results Specific teamwork skills and behavioural markers were associated with indicators of good team performance. Higher and lower-performing teams differed in information exchange, supporting behaviour and communication, with higher performing teams showing more effective information exchange and communication, and less supporting behaviours. Behavioural markers of shared mental models predicted effective medical management better than teamwork skills. Conclusions The present study replicates and extends previous research by providing new empirical evidence of the significance of specific teamwork skills and a shared mental model for the effective medical management of trauma teams. In addition, the study underlines the generic nature of teamwork skills by demonstrating their transferability from different clinical simulations like the anaesthesia environment to trauma care, as well as the potential usefulness of behavioural frequency analysis in future research on non-technical skills.

    Laparoscopic surgery requires specialized dexterity even beyond that required for open surgery. Decreased tactile feedback, different eye-hand coordination, and translation of a two-dimensional video image into a three-dimensional working area are just some of the obstacles in the performance of laparoscopic surgery. Possession of certain nonsurgical skills may help in overcoming some of these obstacles. Prediction of baseline laparoscopic surgery skills may help further to refine the education of basic laparoscopic surgery skills. This investigation explores whether nonsurgical skills and demographic data can predict baseline laparoscopic surgery tasks. First- and second-year students were given a survey regarding nonsurgical dexterity skills. The survey inquired about typing skills, play with computer games, ability to sew, skill with music instruments, use of chopsticks, and experience operating tools. Demographic data were requested as well. All the students underwent four tasks: placing a piece of bowel in a retrieval bag, placing a stapler on the bowel, measuring a piece of bowel, and performing a liver biopsy in a porcine animal model. Both objective (time and error) and subjective evaluation were assessed for all the tasks. Statistical analysis using analysis of variances (ANOVA) Kruskal-Wallis test with post hoc tests, two-tailed unpaired t-tests/Mann-Whitney test, and Fischer's exact tests/chi-square tests was performed when appropriate. There were 68 students in this investigation. Gender, medical student year, ethnicity, desire to enter a surgical field, and age were not associated with increased performance in any of the tasks. Chopstick use was associated with statistically significantly better mean time in placing a piece of bowel in a retrieval bag and measuring a piece of bowel (p < 0.04). The other nonsurgical dexterity skills did not statistically increase performance, as indicated by time, errors, or subjective scores, for the four tasks. It is

    Technical skills training in neurosurgery is mostly done in the operating room. New educational paradigms are encouraging the development of novel training methods for surgical skills. Simulation could answer some of these needs. This article presents the development of a conceptual training framework for use on a virtual reality neurosurgical simulator. Appropriate tasks were identified by reviewing neurosurgical oncology curricula requirements and performing cognitive task analyses of basic techniques and representative surgeries. The tasks were then elaborated into training modules by including learning objectives, instructions, levels of difficulty, and performance metrics. Surveys and interviews were iteratively conducted with subject matter experts to delimitate, review, discuss, and approve each of the development stages. Five tasks were selected as representative of basic and advanced neurosurgical skill. These tasks were: 1) ventriculostomy, 2) endoscopic nasal navigation, 3) tumor debulking, 4) hemostasis, and 5) microdissection. The complete training modules were structured into easy, intermediate, and advanced settings. Performance metrics were also integrated to provide feedback on outcome, efficiency, and errors. The subject matter experts deemed the proposed modules as pertinent and useful for neurosurgical skills training. The conceptual framework presented here, the Fundamentals of Neurosurgery, represents a first attempt to develop standardized training modules for technical skills acquisition in neurosurgical oncology. The National Research Council Canada is currently developing NeuroTouch, a virtual reality simulator for cranial microneurosurgery. The simulator presently includes the five Fundamentals of Neurosurgery modules at varying stages of completion. A first pilot study has shown that neurosurgical residents obtained higher performance scores on the simulator than medical students. Further work will validate its components and use in a

    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.

This interpretive-constructivist case study was located in evaluation research. Data were collected by means of classroom observations and interviews with 35 students and 14 former students. Findings indicated that introducing students to a PBL approach did promote more meaningful learning patterns, typified by processing the subject matter critically and self-regulating learning processes. The sustainability ofthe meaning-directed learning skills was questionable ifstudent beliefs in the approach did not support the activities employed.

    This study describes a pilot project in which peer assisted learning (PAL) is used to teach dental clinical skills. A cluster randomised controlled trial compared opinions of Bachelor of Dental Surgery (BDS) students from peer-led groups versus staff-led groups in a clinical (impression taking) and a pre-clinical (handpiece skills) task. BDS5 (peer tutors) in their final year delivered teaching to BDS1 (tutees) for each task. Quantitative data from tutees and the peer tutors was gathered from questionnaires, along with open written comments. PAL was well received by both tutees and peer tutors. BDS1 tutees rated BDS5 peer tutors highly for delivery of information, and level of feedback. The tutees considered peer tutors more approachable and less intimidating than staff. Peer tutors reported their own knowledge had increased as a result of teaching. In a summative OSCE (objective structured clinical examination) four months following the teaching, no statistical significant difference between the performance of peer-led and staff-led groups was found at stations related to the subject matter in question. It is argued that PAL, as well as being a useful method of delivering subject-specific teaching, is able to contribute to the development of graduate attributes.

    2011-03-01

    Medical Education 2011: 45: 217-226 Objectives  The view that training in communication skills produces skilled communication is sometimes criticised by those who argue that communication is individual and intuitive. We therefore examine the validity of the concept of communication as a skill and identify alternative principles to underpin future development of this field. Methods  We critically examine research evidence about the nature of clinical communication, and draw from theory and evidence concerning education and evaluation, particularly in creative disciplines. Results  Skilled communication cannot be fully described using the concept of communication skills. Attempts to do so risk constraining and distorting pedagogical development in communication. Current education practice often masks the difficulties with the concept by introducing subjectivity into the definition and assessment of skills. As all clinical situations differ to some extent, clinical communication is inherently creative. Because it is rarely possible to attribute specific effects to specific elements of communication, communication needs to be taught and evaluated holistically. Conclusions  For communication teaching to be pedagogically and clinically valid in supporting the inherent creativity of clinical communication, it will need to draw from education theory and practice that have been developed in explicitly creative disciplines. © Blackwell Publishing Ltd 2011.

    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.

    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.

  6. Teaching Skills through Literature

    Saleh Ahmed Saif Abdulmughni

    2016-03-01

    Full Text Available This study tries to investigate the contributory factors in the success and failure in teaching of the four language skills through teaching of literature because literature is critically and crucially relevant to the evolution of a literary sensibility. The basic end of literature is to read which develops reading skills and to reinterpret the dynamics of a given society. In this process the language skills are actually manifested. Literature, if we deconstruct the term involves two stages of reading; one that is the text, and second; the subsequent evaluation which entails the ability to break the text and trace the possibilities of meanings. This cannot be done without a proper perspective of the literary and linguistic mind, and the very act of interpretation amply appropriates reading skills. Literature fundamentally helps to develop the spirit of inquiry and the variety of thoughts involved in the representation of the text and; therefore, the study of literature enhances the ability to think beyond what you have been provided with and also to be equipped with a quizzical bent of mind that seeks to establish the competence to question what is read as a matter of literary text. This makes the learner naturally acquire the language from the literary context and consequently develop the language skills. Teaching of language through literature has been a tested method as literary texts are so complete with vocabulary, the terrain of thoughts, the diversity of human encounters and the complexity of experiences. In the process of deconstructing a text, one comes across umpteen shades of thoughts conceived and delivered in a compressed form. Also the decoding of the language given its symbolic structure greatly enhances the prospects of independent thinking and writing. In this way the written skills are widely developed. A text is a bundle of thoughts clad in a complicated web of linguistic sophistication, and the sophistry alone suffices to

    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.

  14. 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...

  17. Measuring Science Inquiry Skills in Youth Development Programs: The Science Process Skills Inventory

    Directory of Open Access Journals (Sweden)

    Mary E. Arnold

    2013-03-01

    Full Text Available In recent years there has been an increased emphasis on science learning in 4-H and other youth development programs. In an effort to increase science capacity in youth, it is easy to focus only on developing the concrete skills and knowledge that a trained scientist must possess. However, when science learning is presented in a youth-development setting, the context of the program also matters. This paper reports the development and testing of the Science Process Skills Inventory (SPSI and its usefulness for measuring science inquiry skill development in youth development science programs. The results of the psychometric testing of the SPSI indicated the instrument is reliable and measures a cohesive construct called science process skills, as reflected in the 11 items that make up this group of skills. The 11 items themselves are based on the cycle of science inquiry, and represent the important steps of the complete inquiry process.

    2017-07-01

    It is known that physical coupling between two subjects may be advantageous in joint tasks. However, little is known about how two people mutually exchange information to exploit the coupling. Therefore, we adopted a reversed, novel perspective to the standard one that focuses on the ability of physically coupled subjects to adapt to cooperative contexts that require negotiating a common plan: we investigated how training in pairs on a novel task affects the development of motor skills of each of the interacting partners. The task involved reaching movements in an unstable dynamic environment using a bilateral non-linear elastic tool that could be used bimanually or dyadically. The main result is that training with an expert leads to the greatest performance in the joint task. However, the performance in the individual test is strongly affected by the initial skill level of the partner. Moreover, practicing with a peer rather than an expert appears to be more advantageous for a naive; and motor skills can be transferred to a bimanual context, after training with an expert, only if the non-expert subject had prior experience of the dynamics of the novel task.

    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.

    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.

    1999-11-26

    Patients with autism and Asperger syndrome (AS) are impaired in mindreading and imitation skills. One possibility would be that their 'mirror neuron' system, which matches action execution and observation, does not function properly. To test this hypothesis we compared action-viewing related motor cortex functions in an AS group (one autistic and four AS subjects) and eight control subjects. In both groups viewing hand actions modified the neuromagnetic approximately 20 Hz oscillatory activity in the primary motor cortex to the same extent. Thus impaired mindreading and imitation skills found in AS and autism do not seem to result from dysfunction of the motor cortex part of the action execution/observation system.

  7. 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.

  9. Physical Exercise Keeps the Brain Connected: Biking Increases White Matter Integrity in Patients With Schizophrenia and Healthy Controls.

    It has been shown that learning a new skill leads to structural changes in the brain. However, it is unclear whether it is the acquisition or continuous practicing of the skill that causes this effect and whether brain connectivity of patients with schizophrenia can benefit from such practice. We examined the effect of 6 months exercise on a stationary bicycle on the brain in patients with schizophrenia and healthy controls. Biking is an endemic skill in the Netherlands and thus offers an ideal situation to disentangle the effects of learning vs practice. The 33 participating patients with schizophrenia and 48 healthy individuals were assigned to either one of two conditions, ie, physical exercise or life-as-usual, balanced for diagnosis. Diffusion tensor imaging brain scans were made prior to and after intervention. We demonstrate that irrespective of diagnosis regular physical exercise of an overlearned skill, such as bicycling, significantly increases the integrity, especially of motor functioning related, white matter fiber tracts whereas life-as-usual leads to a decrease in fiber integrity. Our findings imply that exercise of an overlearned physical skill improves brain connectivity in patients and healthy individuals. This has important implications for understanding the effect of fitness programs on the brain in both healthy subjects and patients with schizophrenia. Moreover, the outcome may even apply to the nonphysical realm. © The Author 2015. Published by Oxford University Press on behalf of the Maryland Psychiatric Research Center. All rights reserved.

  11. Language matters: an introduction.

    Science.gov (United States)

    Leap, William L; Provencher, Denis M

    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.

  12. I. SPATIAL SKILLS, THEIR DEVELOPMENT, AND THEIR LINKS TO MATHEMATICS.

    Science.gov (United States)

    Verdine, Brian N; Golinkoff, Roberta Michnick; Hirsh-Pasek, Kathy; Newcombe, Nora S

    2017-03-01

    Understanding the development of spatial skills is important for promoting school readiness and improving overall success in STEM (science, technology, engineering, and mathematics) fields (e.g., Wai, Lubinski, Benbow, & Steiger, 2010). Children use their spatial skills to understand the world, including visualizing how objects fit together, and can practice them via spatial assembly activities (e.g., puzzles or blocks). These skills are incorporated into measures of overall intelligence and have been linked to success in subjects like mathematics (Mix & Cheng, 2012) and science (Pallrand & Seeber, 1984; Pribyl & Bodner, 1987). This monograph sought to answer four questions about early spatial skill development: 1) Can we reliably measure spatial skills in 3- and 4-year-olds?; 2) Do spatial skills measured at 3 predict spatial skills at age 5?; 3) Do preschool spatial skills predict mathematics skills at age 5?; and 4) What factors contribute to individual differences in preschool spatial skills (e.g., SES, gender, fine-motor skills, vocabulary, and executive function)? Longitudinal data generated from a new spatial skill test for 3-year-old children, called the TOSA (Test of Spatial Assembly), show that it is a reliable and valid measure of early spatial skills that provides strong prediction to spatial skills measured with established tests at age 5. New data using this measure finds links between early spatial skill and mathematics, language, and executive function skills. Analyses suggest that preschool spatial experiences may play a central role in children's mathematical skills around the time of school entry. Executive function skills provide an additional unique contribution to predicting mathematical performance. In addition, individual differences, specifically socioeconomic status, are related to spatial and mathematical skill. We conclude by exploring ways of providing rich early spatial experiences to children. © 2017 The Society for Research in Child

  13. Internet skill-related problems in accessing online health information.

    2012-01-01

    Despite the amount of health information available online, there are several barriers that limit the Internet from being adopted as a source of health information. The purpose of this study was to identify individual skill-related problems that users experience when accessing the Internet for health information and services. Between November 2009 and February 2010, 88 subjects participated in a performance test in which participants had to complete health-related assignments on the Internet. Subjects were randomly selected from a telephone book. A selective quota sample was used and was divided over equal subsamples of gender, age, and education. Each subject was required to complete nine assignments on the Internet. The general population experiences many Internet skill-related problems, especially those related to information and strategic Internet skills. Aging and lower levels of education seemed to contribute to the amount of operational and formal skill-related problems experienced. Saving files, bookmarking websites, and using search engines were troublesome for these groups of people. With respect to information skills, the higher the level of educational attainment, the less problems the participants experienced. Although younger subjects experienced far less operational and formal skill-related problems, it was revealed that older subjects were less likely to select and use irrelevant search results and unreliable sources. Concerning the strategic Internet skills it was revealed that older subjects were less likely to make inappropriate decisions based on information gathered. The amount of online health-related information and services is consistently growing; however, it appears that the general population experiences many skill-related problems, particularly those related to information and strategic Internet skills, and they become very important when it comes to health. These skills are also problematic for younger generations who are often seen as

  14. Media matters.

    Science.gov (United States)

    Martinez, L M

    1995-01-01

    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.

El autor propone una aproximación distinta a este campo de investigación con respecto al que han propuesto John Searle y Daniel Vanderveken. Ellos conciben la lógica ilocucionaria como un suplemento o un apéndice a la lógica estándar, la lógica de los enunciados, y se concentran en el estudio de leyes y principios muy generales que caracterizan todo tipo de actos ilocucionarios. Kearns, en cambio, concibe la lógica ilocucionaria como una disciplina muy comprensiva, con muchos subsistemas, que cobija a la lógica estándar como parte suya. El escrito describe brevemente el uso de los operadores ilocucionarios (de aseveración, de negación, de suposición de verdad o falsedad, explica la manera como se expande la concepción semántica en términos de condiciones de verdad para incluir los compromisos racionales del hablante y presenta un sistema de deducción para esta lógica.

    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.

    Wassermann, Demian; Makris, Nikos; Rathi, Yogesh; Shenton, Martha; Kikinis, Ron; Kubicki, Marek; Westin, Carl-Fredrik

    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.

    Full Text Available In the field of religious education, pedagogies have featured regularly as teachers strive for the most effective methodology to promote pupils’ learning but their current success rate has been called into question by two critical Subject Reports in 2010 and 2013 from the English Government’s Office for Standards in Education (OfSTED. This paper reports on a piece of action research that sets Bloom’s taxonomy within a framework of classroom dialogue skills with the intention of addressing the OfSTED-identified shortcomings. Furthermore, the paper proposes that in a world where young people often hear and see a close relationship between religion and conflict, religious education cannot remain silent and the skills for enhancing dialogue in the classroom may also have a contribution to make to issues around religion, conflict and education.

    2003-01-01

    To investigate the relations between premorbid and current mental ability, mood, and white matter signal abnormalities detected by T2 weighted brain magnetic resonance imaging (MRI) and impairment of balance and mobility in older adults. 97 subjects from the Aberdeen 1921 birth cohort underwent brain MRI, evaluation of balance, and measurement of gait speed. White matter hyperintensities detected on T2 weighted MRI scans were rated by three independent raters on three variables: white matter lesions; periventricular lesions; and brain stem lesions. Decreased gait speed was correlated with impaired visual acuity (p = 0.020), shorter stature (p = 0.008), a lower childhood IQ (p = 0.030), a lower current Raven's progressive matrices score (Raven score) (p balance was correlated with Raven score (p = 0.042), brain stem lesions (p = 0.003), white matter lesions (p = 0.003), and periventricular lesions (p = 0.038). Binary logistic regression identified brain stem lesions (odds ratio (OR) 0.22; 95% confidence interval 0.09 to 0.54) and HADS depression score (OR 0.75; 0.58 to 0.97) as the only significant associations with balance. Structural equation modelling detected an association between two latent traits representing white matter disease and an integrating function, respectively. In this cohort, white matter lesions, periventricular lesions, and brain stem lesions were associated with impaired balance. Current mental ability was strongly related to gait speed. There appears to be a concordance between motor skills and intellect in old age, which is degraded by white matter disease.

    2017-12-01

    Geometry is one of the difficult materials for students because students must have the ability to visualize, describe the picture, draw a figure, and know the kinds of figures. This study aimisto describe the students geometry skills in resolving geometry problems viewed from spatial intelligence. This research uses a descriptive qualitative method has aim to identify students geometry skills by 6 students in eight grade of Ngawi regency, Indonesia. The subjects were 2 students with high spatial intelligence, 2 students with medium spatial intelligence, and 2 students with low spatial intelligence. Datas were collected based on written test and interview. The result of this research showed that the students geometry skills viewed from spatial intelligence includes. The results of this study indicate that there was a correlation between students' spatial intelligence with geometric skills. Students had different geometric skills in each category of spatial intelligence, although there were similarities in some geometry skill indicators. Students with low spatial intelligence had less geometry skills, thus requiring special attention from teachers. Mathematics teachers are expected to provide more practice questions that reinforce students' geometry skills including visual skills, descriptive skills, drawing skills, logical skills, applied skills.

  16. Simulated and Virtual Science Laboratory Experiments: Improving Critical Thinking and Higher-Order Learning Skills

    Science.gov (United States)

    Simon, Nicole A.

    Virtual laboratory experiments using interactive computer simulations are not being employed as viable alternatives to laboratory science curriculum at extensive enough rates within higher education. Rote traditional lab experiments are currently the norm and are not addressing inquiry, Critical Thinking, and cognition throughout the laboratory experience, linking with educational technologies (Pyatt & Sims, 2007; 2011; Trundle & Bell, 2010). A causal-comparative quantitative study was conducted with 150 learners enrolled at a two-year community college, to determine the effects of simulation laboratory experiments on Higher-Order Learning, Critical Thinking Skills, and Cognitive Load. The treatment population used simulated experiments, while the non-treatment sections performed traditional expository experiments. A comparison was made using the Revised Two-Factor Study Process survey, Motivated Strategies for Learning Questionnaire, and the Scientific Attitude Inventory survey, using a Repeated Measures ANOVA test for treatment or non-treatment. A main effect of simulated laboratory experiments was found for both Higher-Order Learning, [F (1, 148) = 30.32,p = 0.00, eta2 = 0.12] and Critical Thinking Skills, [F (1, 148) = 14.64,p = 0.00, eta 2 = 0.17] such that simulations showed greater increases than traditional experiments. Post-lab treatment group self-reports indicated increased marginal means (+4.86) in Higher-Order Learning and Critical Thinking Skills, compared to the non-treatment group (+4.71). Simulations also improved the scientific skills and mastery of basic scientific subject matter. It is recommended that additional research recognize that learners' Critical Thinking Skills change due to different instructional methodologies that occur throughout a semester.

    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.

    Full Text Available Racial and ethnic minority health data from a national perspective indicates there is much to learn in the public health workforce about the ongoing health disparities crisis. This suggests a level of urgency to assist our public health professionals in obtaining specific skills sets that will assist them in working better with vulnerable populations. The purpose of this research is to assess cultural competence knowledge and programmatic skill sets, utilizing an explorational case study, of individuals employed within an urban public health department. In order to effectively evaluate these constructs, a quantitative research approach was employed to examine participants’ knowledge and competencies of the subject matter. This data was further analyzed to determine if continuing education participation and training was correlated to the levels of culturally competent practice engagement and self-reported confidence. In addition, researchers obtained data on the availability of employer sponsored training opportunities. The data suggested when health professionals engage in cultural competence education, their level of awareness of unique characteristics between ethnic and racial minorities increased. Those who exhibited the healthiest behaviors, as it relates to effectively working with diverse populations, had a heightened sense of knowledge related to culture and healthcare services. Continuing education in cultural competence is an essential strategy for improving public health employees’ effectiveness in working with diverse clients and reducing racial and ethnic health disparities. As the finding illustrated, training programs must incorporate educational components which foster skill building to enable subsequent culturally appropriate clinical interactions.

  7. Asthma and child behavioral skills: does family socioeconomic status matter?

    Science.gov (United States)

    Chen, Jen-Hao

    2014-08-01

    Asthma is associated with poorer behavioral and psychological outcomes in children, yet little is known about whether and how the social stratification process affects the impacts of asthma on children's outcomes. Using data from the Early Childhood Longitudinal Study-Birth Cohort, this study considered the role of socioeconomic status in shaping the developmental consequences of children's asthma. Results showed that asthma was negatively associated with attention and social competence and positively associated with externalizing problem behaviors for children with low-educated mothers and children who lived in poor households. However, the adverse consequences of asthma disappeared for children with high-educated mothers and children who did not experience poverty. Additionally, the socioeconomic disparities were not fully explained by healthcare resources, family process, and exposure to environment risks and the disparities were found for both mild and severe cases. These findings suggest that, to fully understand the developmental consequences of illness in children, it is important to place socioeconomic status at the center of investigation.

    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.

    Full Text Available This article presents the results of a study aimed to investigate the requirements of the business sector in light of the skills and competencies students should have in order to be recruited. In this fashion, the study intended to measure the importance of the skills and competencies sought by the business world, revealing ways through which students can develop such skills. This project portrayed that, some of the required classes will certainly give students a strong theoretical background but they will neither completely prepare this student with all possible skills or competencies nor provide the student with any practical experience that will enable him/her to be more competitive when entering the business market. In some classes, however, like Public Speaking, which is designed to teach presentation skills, successful students are able to build good communication and interpersonal skills. Additionally, an English writing class will certainly attempt to provide them with strong writing skills, and a business class will possibly demand reading skills. Moreover, a calculus and a statistics class will provide basic arithmetic/mathematical skills. However, through this project it is proven that all of these classes will neglect the indoctrination of creative thinking in students, or make students believe in their own self-worth (self-esteem skills; the courses will also fail to develop the sense of urgency, drive and determination that students should possess not just to compete but also to survive in a business world.

    Full Text Available The population from which we extracted a sample of 76 subjects consisted of elementary school students in Kursumlija, all male, aged 12-13, who were divided into a sub-sample consisting of 38 young handball players who took part in the training sessions of a school of handball and another sub-sample consisting of 38 non-athletes, who only took part in their regular physical education classes. The aim of the research was to determine the transformation processes involving motor skills, which occur under the influence of basic preliminary training in young handball players. The subject matter of the study was to examine whether a statistically significant increase in the level of motor skills would occur under the influence of physical exercise as part of basic preliminary training in the final as compared to the initial state. Six motor tests which define the dimensions of explosive and repetitive strength were used. The results of the research indicate that significant transformational processes involving the motor skills of young handball players occurred in the final as compared to the initial measuring, under the influence of basic preliminary training.

  1. Sensibility and Subjectivity: Levinas’ Traumatic Subject

    Directory of Open Access Journals (Sweden)

    Rashmika Pandya

    2011-02-01

    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.

    The purpose of the study was to compare the self-skills assessment with the skill competence during an actual skills demonstration of newly hired bachelor of science in nursing (BSN) registered nurse graduates. This retrospective study included 32 randomly selected BSN registered nurse graduates from January 2010 to December 31, 2010. The participants were already hired into a midwest health system. Because this was a retrospective study, no demographic data were collected, and no consent from participants was needed. This study included a clinical skills check list where the participants rated themselves on specific skills utilizing a Likert scale ranging from 1 (no knowledge) to 4 (able to perform independently). The same clinical check list was utilized by an expert registered nurse when the skill was demonstrated. This study compared the difference between the subject's self-rating of skills and the clinical demonstration of the skills. We used t tests in the analysis to demonstrate the differences between the participant's self-rating of skills and the expert evaluation of the clinical demonstration of the skills. The data were inserted into the Statistical Package for the Social Sciences 19 software program to assist in the analysis process. The study demonstrated 17 significant differences in the skills ratings between the participant and competency demonstration of new BSN graduates. These significant results (2 tailed) ranged from .000 to .048.The 17 out of 46 specific skills where differences were noted included the following: staple removal, nasal pharyngeal suctioning, urinary catheter specimen collection, site care dressing change, urinary catheter irrigation, Juzo application and measurement, 5-lead telemetry, oral airway insertion, hemovac/Jackson Pratt, oral pharyngeal suctioning, urinary catheter insertion, dry suction chest drainage, bed to cart/slider board, urinary catheter removal, antiembolism stockings, measurement and application, removal of

    Good communication skills are essential for an optimal doctor-patient relationship, and also contribute to improved health outcomes. Although the need for training in communication skills is stated as a requirement in the 1997 Graduate Medical Education Regulations of the Medical Council of India, formal training in these skills has been fragmentary and non-uniform in most Indian curricula. The Vision 2015 document of the Medical Council of India reaffirms the need to include training in communication skills in the MBBS curriculum. Training in communication skills needs approaches which are different from that of teaching other clinical subjects. It is also a challenge to ensure that students not only imbibe the nuances of communication and interpersonal skills, but adhere to them throughout their careers. This article addresses the possible ways of standardizing teaching and assessment of communication skills and integrating them into the existing curriculum.

    Snowboarding-related injuries have been associated with specific snowboarding skill levels, but differences in specific skill level have not been identified. Injury patterns are different among skill levels. Descriptive epidemiology study. The subjects were 19 539 snowboarders from the Oku-Mino region in Gifu Prefecture, Japan, who were admitted to our hospital during the 12 snowboarding seasons from 1996 to 2008. They were asked to complete a questionnaire regarding age, gender, self-estimated skill level, injury location, injury type, mechanism of injury, and protective gear. Physicians documented diagnostic variables and injury severity score; these variables were compared among the self-estimated skill levels. Of the total 19 539 injured snowboarders, 1204 (6.2%) were novices, 6409 (32.8%) were beginners, 9260 (47.4%) were intermediates, 1918 (9.8%) were experts, and the skill level was not known in 748 (3.8%). Proportions of the trunk and multiple injuries increased with increases in skill level; however, the number of head/face injuries decreased with increase in skill level. Upper extremity injuries also decreased with increase in skill level, except in novices. Dislocations and multiple injuries increased with increase in skill level, while lacerations/contusions, fractures, and bruises decreased. The mean overall injury severity score was 3.28 + or - 0.02, and the value increased significantly with increase in skill level. The proportion of collision and isolated fall injuries significantly decreased with increase in skill level, but that of jump injuries significantly increased. The percentage of protective gear use increased with the increase in skill level. Prevalence of injury type, injury location, mechanism of injury, and percentage of protective gear use varied according to skill level, and the severity of the injury increased with increase in skill level. On the basis of our observations, we believe that snowboarding injury prevention strategies

    We consider dark matter models in which the mass splitting between the dark matter particles and their annihilation products is tiny. Compared to the previously proposed Forbidden Dark Matter scenario, the mass splittings we consider are much smaller, and are allowed to be either positive or negative. To emphasize this modification, we dub our scenario “Impeded Dark Matter”. We demonstrate that Impeded Dark Matter can be easily realized without requiring tuning of model parameters. For negative mass splitting, we demonstrate that the annihilation cross-section for Impeded Dark Matter depends linearly on the dark matter velocity or may even be kinematically forbidden, making this scenario almost insensitive to constraints from the cosmic microwave background and from observations of dwarf galaxies. Accordingly, it may be possible for Impeded Dark Matter to yield observable signals in clusters or the Galactic center, with no corresponding signal in dwarfs. For positive mass splitting, we show that the annihilation cross-section is suppressed by the small mass splitting, which helps light dark matter to survive increasingly stringent constraints from indirect searches. As specific realizations for Impeded Dark Matter, we introduce a model of vector dark matter from a hidden SU(2) sector, and a composite dark matter scenario based on a QCD-like dark sector.

  7. Collapsed Dark Matter Structures

    The distributions of dark matter and baryons in the Universe are known to be very different: The dark matter resides in extended halos, while a significant fraction of the baryons have radiated away much of their initial energy and fallen deep into the potential wells. This difference in morphology leads to the widely held conclusion that dark matter cannot cool and collapse on any scale. We revisit this assumption and show that a simple model where dark matter is charged under a "dark electromagnetism" can allow dark matter to form gravitationally collapsed objects with characteristic mass scales much smaller than that of a Milky-Way-type galaxy. Though the majority of the dark matter in spiral galaxies would remain in the halo, such a model opens the possibility that galaxies and their associated dark matter play host to a significant number of collapsed substructures. The observational signatures of such structures are not well explored but potentially interesting.

  9. How dark matter came to matter

    2017-03-01

    The history of the dark matter problem can be traced back to at least the 1930s, but it was not until the early 1970s that the issue of 'missing matter' was widely recognized as problematic. In the latter period, previously separate issues involving missing mass were brought together in a single anomaly. We argue that reference to a straightforward accumulation of evidence alone is inadequate to comprehend this episode. Rather, the rise of cosmological research, the accompanying renewed interest in the theory of relativity and changes in the manpower division of astronomy in the 1960s are key to understanding how dark matter came to matter. At the same time, this story may also enlighten us on the methodological dimensions of past practices of physics and cosmology.

    It is well known that dark matter density measurements, indirect and direct detection experiments, importantly complement the LHC in setting strong constraints on new physics scenarios. Yet, dark matter searches are subject to limitations which need to be considered for realistic analyses. For illustration, we explore the parameter space of the phenomenological MSSM and discuss the interplay of the constraints from dark matter searches and the LHC, and analyse the impact of the astrophysical uncertainties in some detail.

    2016-07-01

    The study evaluated whether a modified version of the information literacy Valid Assessment of Learning in Undergraduate Education (VALUE) rubric would be useful for assessing the information literacy skills of graduate health sciences students. Through facilitated calibration workshops, an interdepartmental six-person team of librarians and faculty engaged in guided discussion about the meaning of the rubric criteria. They applied the rubric to score student work for a peer-review essay assignment in the "Information Literacy for Evidence-Based Practice" course. To determine inter-rater reliability, the raters participated in a follow-up exercise in which they independently applied the rubric to ten samples of work from a research project in the doctor of physical therapy program: the patient case report assignment. For the peer-review essay, a high level of consistency in scoring was achieved for the second workshop, with statistically significant intra-class correlation coefficients above 0.8 for 3 criteria: "Determine the extent of evidence needed," "Use evidence effectively to accomplish a specific purpose," and "Access the needed evidence." Participants concurred that the essay prompt and rubric criteria adequately discriminated the quality of student work for the peer-review essay assignment. When raters independently scored the patient case report assignment, inter-rater agreement was low and statistically insignificant for all rubric criteria (kappa=-0.16, p>0.05-kappa=0.12, p>0.05). While the peer-review essay assignment lent itself well to rubric calibration, scorers had a difficult time with the patient case report. Lack of familiarity among some raters with the specifics of the patient case report assignment and subject matter might have accounted for low inter-rater reliability. When norming, it is important to hold conversations about search strategies and expectations of performance. Overall, the authors found the rubric to be appropriate for

    2007-01-01

    The importance of accurate early diagnostics of autism that severely affects personal behavior and communication skills cannot be overstated. Neuropathological studies have revealed an abnormal anatomy of the cerebral white matter (CWM) in autistic brains. We explore a possibility of distinguishing between autistic and normal brains by a quantitative shape analysis of CWM gyrifications on 3D proton density MRI (PD-MRI) images. Our approach consists of (i) segmentation of the CWM on a 3D brain image using a deformable 3D boundary; (ii) extraction of gyrifications from the segmented CWM, and (iii) shape analysis to quantify thickness of the extracted gyrifications and classify autistic and normal subjects. The boundary evolution is controlled by two probabilistic models of visual appearance of 3D CWM: the learned prior and the current appearance model. Initial experimental results suggest that the proposed 3D texture analysis is a promising supplement to the current techniques for diagnosing autism.

    Simulations from chemical weather models are subject to uncertainties in the input data (e.g. emission inventory, initial and boundary conditions) as well as those intrinsic to the model (e.g. physical parameterization, chemical mechanism). Multi-model ensembles can improve the forecast skill, provided that certain mathematical conditions are fulfilled. In this work, four ensemble methods were applied to two different datasets, and their performance was compared for ozone (O3), nitrogen dioxide (NO2) and particulate matter (PM10). Apart from the unconditional ensemble average, the approach behind the other three methods relies on adding optimum weights to members or constraining the ensemble to those members that meet certain conditions in time or frequency domain. The two different datasets were created for the first and second phase of the Air Quality Model Evaluation International Initiative (AQMEII). The methods are evaluated against ground level observations collected from the EMEP (European Monitoring and Evaluation Programme) and AirBase databases. The goal of the study is to quantify to what extent we can extract predictable signals from an ensemble with superior skill over the single models and the ensemble mean. Verification statistics show that the deterministic models simulate better O3 than NO2 and PM10, linked to different levels of complexity in the represented processes. The unconditional ensemble mean achieves higher skill compared to each station's best deterministic model at no more than 60 % of the sites, indicating a combination of members with unbalanced skill difference and error dependence for the rest. The promotion of the right amount of accuracy and diversity within the ensemble results in an average additional skill of up to 31 % compared to using the full ensemble in an unconditional way. The skill improvements were higher for O3 and lower for PM10, associated with the extent of potential changes in the joint distribution of accuracy

    Full Text Available Context: During the third semester of a 6 year long curriculum medical students train clinical skills in the skills laboratory (2 hours per week for 9 weeks as well as in an early, 8 week clinical clerkship at county hospitals. Objectives: to study students’ expectations and attitudes towards skills training in the skills laboratory and clerkship. Subjects: 126 medical students in their 3rd semester. Methods: During the fall of 2001 three consecutive, constructed questionnaires were distributed prior to laboratory training, following laboratory training but prior to clerkships, and following clerkships respectively. Results: Almost all (98% respondents found that training in skills laboratory improved the outcome of the early clerkship and 70% believed in transferability of skills from the laboratory setting to clerkship. Still, a majority (93% of students thought that the clerkship provided students with a better opportunity to learn clinical skills when compared to the skills laboratory. Skills training in laboratory as well as in clerkship motivated students for becoming doctors. Teachers in both settings were perceived as being committed to their teaching jobs, to demonstrate skills prior to practice, and to give students feed back with a small but significant more positive rating of the laboratory. Of the 22 skills that students had trained in the laboratory, a majority of students tried out skills associated with physical examination in the clerkship, whereas only a minority of students tried out more intimate skills. Female medical students tried significantly fewer skills during their clerkship compared to male students. Conclusions: Students believe that skills laboratory training prepare them for their subsequent early clerkship but favour the clerkship over the laboratory

  7. Codecaying Dark Matter.

    Dror, Jeff Asaf; Kuflik, Eric; Ng, Wee Hao

    2016-11-18

    We propose a new mechanism for thermal dark matter freeze-out, called codecaying dark matter. Multicomponent dark sectors with degenerate particles and out-of-equilibrium decays can codecay to obtain the observed relic density. The dark matter density is exponentially depleted through the decay of nearly degenerate particles rather than from Boltzmann suppression. The relic abundance is set by the dark matter annihilation cross section, which is predicted to be boosted, and the decay rate of the dark sector particles. The mechanism is viable in a broad range of dark matter parameter space, with a robust prediction of an enhanced indirect detection signal. Finally, we present a simple model that realizes codecaying dark matter.

    Wunder, Linda L

    2016-02-01

    Simulation-based education provides a safe place for student registered nurse anesthetists to practice non-technical skills before entering the clinical arena. An anesthetist's lack of nontechnical skills contributes to adverse patient outcomes. The purpose of this study was to determine whether an educational intervention on nontechnical skills could improve the performance of nontechnical skills during anesthesia crisis simulation with a group of first-year student registered nurse anesthetists. Thirty-two first-year students volunteered for this quasi-experimental study. Each subject was videotaped and rated as he or she performed 6 simulated crisis scenarios: 3 scenarios before the intervention and 3 after the intervention. Findings revealed that the nontechnical skills mean posttest score was greater than pretest scores: t (df = 31) = 1.99, P = .028. The mean gain in scores for standardized nontechnical skills were significantly greater than those for standardized technical skills: t (df = 30) = 1.81, P = .04. In conclusion, a 3-hour educational intervention on nontechnical skills resulted in significant improvement. Nontechnical skills therefore are not acquired through experience, but rather through instruction. An educational intervention using the Anaesthetists' Non-Technical Skills system is a valuable tool in the measurement of nontechnical skills assessment of first-year student registered nurse anesthetists.

    The astronomical dark matter could be made of weakly interacting and massive particles. If so, these species would be abundant inside the Milky Way, where they would continuously annihilate and produce cosmic rays. Those annihilation products are potentially detectable at the Earth, and could provide indirect clues for the presence of dark matter species within the Galaxy. We will review here the various cosmic radiations which the dark matter can produce. We will examine how they propagate t...

    A study is conducted of cold dark matter (CDM) models in which clumpiness will inhere, using cosmic strings and textures suited to galaxy formation. CDM clumps of 10 million solar mass/cu pc density are generated at about z(eq) redshift, with a sizable fraction surviving. Observable implications encompass dark matter cores in globular clusters and in galactic nuclei. Results from terrestrial dark matter detection experiments may be affected by clumpiness in the Galactic halo.

    Soft matter (polymers, colloids, surfactants and liquid crystals) are an important class of materials in modern technology. They also form the basis of many future technologies, for example in medical and environmental applications. Soft matter shows complex behaviour between fluids and solids, and used to be a synonym of complex materials. Due to the developments of the past two decades, soft condensed matter can now be discussed on the same sound physical basis as solid condensedmatter. The purpose of this book is to provide an overview of soft matter for undergraduate and graduate students

    2000-01-01

    The fact that the mass of the visible stars could not account for the gravitational cohesion of the galaxies was the first sign of non-visible (i.e. dark) matter in the Universe. Since then, many observational evidences tell us that most of the matter is indeed dark. The nature of this dark matter is still unknown. There are good reasons to think that most of it is not composed of normal matter. These lectures will review the experimental methods, which have been developed to unravel this mystery and will compare their results with theoretical predictions.

    2017-09-01

    Multiple access technique is one of important techniques within medium access layer in TCP/IP protocol stack. Each network technology implements the selected access method. Priority can be implemented in those methods to differentiate services. Some internet networks are dedicated for specific purpose. Education browsing or tutorial video accesses are preferred in a library hotspot, while entertainment and sport contents could be subjects of limitation. Current solution may use IP address filter or access list. This paper proposes subjective properties of users or applications are used for priority determination in multiple access techniques. The NS-2 simulator is employed to evaluate the method. A video surveillance network using WiMAX is chosen as the object. Subjective priority is implemented on WiMAX scheduler based on traffic properties. Three different traffic sources from monitoring video: palace, park, and market are evaluated. The proposed subjective scheduler prioritizes palace monitoring video that results better quality, xx dB than the later monitoring spots.

  1. Increasing money-counting skills with a student with brain injury: skill and performance deficits.

    Fienup, Daniel M; Mudgal, Dipti; Pace, Gary

    2013-01-01

    Two studies examined the effectiveness of interventions designed to increase money-counting skills of a student with brain injury. Both skill and performance hypotheses were examined. Single subject designs were used to evaluate interventions, including a multiple-baseline across counting paper and coin money (study 1) and a changing criterion design (study 2). In study 1, it was hypothesized that the student had a skill deficit; thus, the participant was taught organizational strategies for counting money. In study 2, a performance deficit was hypothesized and the effects of contingent rewards were evaluated. In study 1, organizational strategies increased organized counting of money, but did not affect counting accuracy. In study 2, contingent rewards increased accurate money counting. When dealing with multi-step behaviours, different components of behaviour can be controlled by different variables, such as skill and performance deficits. Effective academic interventions may need to consider both types of deficits.
