    Even though the first ultraviolet microbeam was described by S. Tschachotin back in 1912, the development of sophisticated micro-irradiation facilities only began to flourish in the late 1980s. In this article, we highlight significant microbeam experiments, describe the latest microbeam irradiator configurations and critical discoveries made by using the microbeam apparatus. Modern radiological microbeams facilities are capable of producing a beam size of a few micrometers, or even tens of nanometers in size, and can deposit radiation with high precision within a cellular target. In the past three decades, a variety of microbeams has been developed to deliver a range of radiations including charged particles, X-rays, and electrons. Despite the original intention for their development to measure the effects of a single radiation track, the ability to target radiation with microbeams at sub-cellular targets has been extensively used to investigate radiation-induced biological responses within cells. Studies conducted using microbeams to target specific cells in a tissue have elucidated bystander responses, and further studies have shown reactive oxygen species (ROS) and reactive nitrogen species (RNS) play critical roles in the process. The radiation-induced abscopal effect, which has a profound impact on cancer radiotherapy, further reaffirmed the importance of bystander effects. Finally, by targeting sub-cellular compartments with a microbeam, we have reported cytoplasmic-specific biological responses. Despite the common dogma that nuclear DNA is the primary target for radiation-induced cell death and carcinogenesis, studies conducted using microbeam suggested that targeted cytoplasmic irradiation induces mitochondrial dysfunction, cellular stress, and genomic instability. A more recent development in microbeam technology includes application of mouse models to visualize in vivo DNA double-strand breaks. Microbeams are making important contributions towards our

    This paper presents the results of an experiment which investigated the effects of the using science fiction stories in physics lessons. A questionnaire form containing 2 open-ended questions related to Jules Vernes story From the Earth to the Moon was used with 353, 9th and 10th grade students to determine their pre-conceptions about gravity and weightlessness. Mental models explaining students scientific and alternative views were constructed, according to students replies. After these studies, 6 students were interviewed. In this interview, researches were done about whether science fiction stories had an effect on bringing students pre-conceptions related to physics subjects out, on students inquiring their own concepts and on increasing students interest and motivation towards physics subjects. Studies in this research show that science fiction stories have an effect on arousing students interest and curiosity, have a role encouraging students to inquire their own concepts and are effective in making students alternative views come out

    Full Text Available In the present study a model is proposed offering a comprehensive categorization of video game narrative structures intended as the methods and techniques used by game designers and allowed by the medium to deliver the story content throughout the gameplay in collaboration with the players. A case is first made for the presence of narrative in video games and its growth of importance as a central component in game design. An in-depth analysis ensues focusing on how games tell stories, guided by the criteria of linearity/nonlinearity, interactivity and randomness. Light is shed upon the fundamental architectures through which stories are told as well as the essential boundaries posed by the close link between narrative and game AI.

    NASA's Earth Right Now communication team kicked off an ambitious multimedia campaign in March 2016 to tell the stories of eight major field campaigns studying regions of critical change from the land, sea and air. Earth Expeditions focused on the human side of science, with live reporting from the field, behind-the-scenes images and videos, and extended storytelling over a six-month period. We reported from Greenland to Namibia, from the eastern United States to the South Pacific. Expedition scientists explored ice sheets, air quality, coral reefs, boreal forests, marine ecosystems and greenhouse gases. All the while the campaign communications team was generating everything from blog posts and social media shareables, to Facebook Live events and a NASA TV series. We also participated in community outreach events and pursued traditional media opportunities. A massive undertaking, we will share lessons learned, best practices for social media and some of our favorite moments when science communication touched our audience's lives.

    Machine vision systems analyze image data to carry out automation tasks. Our interest is in machine vision systems that rely on models to achieve their designed task. When the model is interrogated from an a priori menu of questions, the model need not be complete. Instead, the machine vision system can use a partial model that contains a large amount of information in regions of interest and less information elsewhere. We propose an adaptive modeling scheme for machine vision, called task-focused modeling, which constructs a model having just sufficient detail to carry out the specified task. The model is detailed in regions of interest to the task and is less detailed elsewhere. This focusing effect saves time and reduces the computational effort expended by the machine vision system. We illustrate task-focused modeling by an example involving real-time micropropagation of plants in automated agriculture.

    This paper uses a crowd-sourced definition of a speech phenomenon we have called focus. Given sentences, text and speech, in isolation and in context, we asked annotators to identify what we term the focus word. We present their consistency in identifying the focused word, when presented with text...... or speech stimuli. We then build models to show how well we predict that focus word from lexical (and higher) level features. Also, using spectral and prosodic information, we show the differences in these focus words when spoken with and without context. Finally, we show how we can improve speech synthesis...

    2005-01-01

    Several models for calculation of the dynamics of Plasma Focus have been developed. All of them begin from the same physic principle: the current sheet run down the anode length, ionizing and collecting the gas that finds in its way.This is known as snow-plow model.Concerning pinch's compression, a MHD model is proposed.The plasma is treated as a fluid , particularly as a high ionized gas.However, there are not many models that, taking into account thermal equilibrium inside the plasma, make approximated calculations of the maximum temperatures reached in the pinch.Besides, there are no models which use those temperatures to estimate the termofusion neutron yield for the Deuterium or Deuterium-Tritium gas filled cases.In the PLADEMA network (Dense Magnetized Plasmas) a code was developed with the objective of describe the plasma focus dynamics, in a conceptual engineering stage.The codes calculates the principal variables (currents, time to focus, etc) and estimates the neutron yield in Deuterium-filled plasma focus devices.It can be affirmed that the code's experimental validation, in its axial and radial stages, was very successfully. However, it was accepted that the compression stage should be formulated again, to find a solution for a large variation of a parameter related with velocity profiles for the particles trapped inside the pinch.The objectives of this work can be stated in the next way : - Check the compression's model hypothesis. Develop a new model .- Implement the new model in the code. Compare results against experimental data of Plasma Focus devices from all around the world [es

    Full Text Available Constraint-based student modelling (CBM is an important technique employed in intelligent tutoring systems to model student knowledge to provide relevant assistance. This paper introduces the Math Story Problem Tutor (MAST, a Web-based intelligent tutoring system for probability story problems, which is able to generate problems of different contexts, types and difficulty levels for self-paced learning. Constraints in MAST are specified at a low-level of granularity to allow fine-grained diagnosis of the student error. Furthermore, MAST extends CBM to address errors due to misunderstanding of the narrative story. It can locate and highlight keywords that may have been overlooked or misunderstood leading to an error. This is achieved by utilizing the role of sentences and keywords that are defined through the Natural Language Generation (NLG methods deployed in the story problem generation. MAST also integrates CBM with scaffolding questions and feedback to provide various forms of help and guidance to the student. This allows the student to discover and correct any errors in his/her solution. MAST has been preliminary evaluated empirically and the results show the potential effectiveness in tutoring students with a decrease in the percentage of violated constraints along the learning curve. Additionally, there is a significant improvement in the results of the post–test exam in comparison to the pre-test exam of the students using MAST in comparison to those relying on the textbook

    Full Text Available INTRODUCTION: Policies affecting alcohol's price and promotion are effective measures to reduce harms. Yet policies targeting populations are unpopular with the public, whose views can be influenced by news framings of policy narratives. In Australia, alcohol taxation receives high news coverage, while advertising restrictions have not until recently, and narratives are highly contested for each. However, research specifically examining how audiences respond to such news stories is scant. We sought to explore audience understanding of news reports about two alcohol policy proposals. METHOD: From June to August 2012, 46 participants were recruited for 8 focus groups in age-brackets of young people aged 18-25 years, parents of young people, and adults aged 25 or older. Groups were split by education. Participants were asked their prior knowledge of alcohol policies, before watching and discussing four news stories about alcohol taxation and advertising. RESULTS: Participants were clear that alcohol poses problems, yet thought policy solutions were ineffective in a drinking culture they viewed as unamenable to change and unaffected by alcohol's price or promotion. Without knowledge of its actual effect on consumption, they cited the 2008 alcopops tax as a policy failure, blaming cheaper substitution. Participants had low knowledge of advertising restrictions, yet were concerned about underage exposure. They offered conditional support for restrictions, while doubting its effectiveness. There was marked distrust of statistics and news actors in broadcasts, yet discussions matched previous research findings. CONCLUSIONS: News coverage has resulted in strong audience understanding of alcohol related problems but framed solutions have not always provided clear messages, despite audience support for policies. Future advocacy will need to continue recent moves to address the links between alcohol's price and promotion with the drinking culture, as well

Background: Using photographs and in-depth interviews, this study provides nuanced insight into influences on first-year PhD students’ lived experiences, with a specific focus on these students’ perceptions of doctoral student well-being. Methodology: Twenty-nine first-year biomedical science PhD students from 15 research institutions were asked to take photographs (Participant Produced Images to illuminate significant influences on their research skill acquisition. The participant-produced photographs were discussed within in-depth phone interviews allowing for a deeper understanding of their lived experiences. Contribution: While students were asked to identify factors influencing their research skill acquisition, unexpectedly, what emerged from these data was students’ clear focus on their concern for their physical and mental well-being. The researchers posit that students’ ability to create a “work-life balance” is the foundation of doctoral student success, especially in the early years of doctoral training. Findings: Findings suggest that it is essential to create a PhD culture in which students feel valued, supported, and nourished, both physically and mentally, for them to develop into successful researchers, teachers, and mentors. Recommendations for Practitioners: Findings suggest that doctoral programs must support a more collaborative work environment for students and help novice students create a work life balance, perhaps by encouraging them to pursue stimulating or fun activities outside their school environment. It is imperative for doctoral students to be confident during their doctoral studies, as a lack of confidence tends to breathe life into poor work habits that stymie well-being and happiness.

    We assess several widely used vector models of a Gaussian laser beam in the context of more accurate vector diffraction integration. For the analysis, we present a streamlined derivation of the vector fields of a uniformly polarized beam reflected from an ideal parabolic mirror, both inside and outside of the resulting focus. This exact solution to Maxwell's equations, first developed in 1920 by V. S. Ignatovsky, is highly relevant to high-intensity laser experiments since the boundary conditions at a focusing optic dictate the form of the focus in a manner analogous to a physical experiment. In contrast, many models simply assume a field profile near the focus and develop the surrounding vector fields consistent with Maxwell's equations. In comparing the Ignatovsky result with popular closed-form analytic vector models of a Gaussian beam, we find that the relatively simple model developed by Erikson and Singh in 1994 provides good agreement in the paraxial limit. Models involving a Lax expansion introduce a divergences outside of the focus while providing little if any improvement in the focal region. Extremely tight focusing produces a somewhat complicated structure in the focus, and requires the Ignatovsky model for accurate representation.

    Research on factors that influence the intention to read suicide awareness material is lacking. To identify how social and state similarities between the featured protagonist of a suicide awareness story and the audience impact on the intent to read similar stories. Laboratory experiment with n = 104 students. Participants were randomly assigned to study groups. In the first group, the role model provided his personal story of crisis and was a student. In the second group, the content was identical but the model was socially dissimilar. The third group read about a topic unrelated to suicide. Depression, identification, and exposure intent were measured after the experiment. Conditional process analysis was carried out. In the group featuring a once-suicidal role model with high social similarity, depression in the audience increased the intention to read similar material in the future via identification with the role model; 82% of individuals wanted to read similar material in the future, but only 50% wanted to do so in the group featuring a dissimilar person. Exposure intention increases via identification when role model and audience characteristics align regarding social traits and the experience of depression. These factors are relevant when developing campaigns targeting individuals with stories of recovery.

  14. Non-hydrodynamic model of plasma focus structure

    1985-01-01

    Experimental and theoretical plasma focus study has resulted in the necessity of creating a non-hydrodynamic plasma focus structure model (MKHD model). This model describes the final stage of plasma focus, which starts immediately after maximum plasma compression. It is related to a very limited space near the neck of the sausage instability. The MKHD model is two-dimensional, axially symmetric and collisionless with respect to the ions and magnetohydrodynamic with respect to the electrons; it accounts for the pinch instability of the sausage type (m=0 mode). The MKHD model, first of all, explains the long time of the plasma focus existence and non-thermonuclear peculiarities in the neutron yield. The initial and boundary conditions are formulated in accordance with the experiments and the results of computations in the 2D MHD model. A non-stationary process of plasma focus dynamics is studied numerically for a relatively long time - about 20 ns; this time is, in principle, not restricted. The computations show that the external edge of the neck expands rather slowly (at a speed that is lower than the thermal ion velocity, by an order of magnitude), and the magnetic field energy is converted to the kinetic energy of the chaotic ion motion (which is doubled for the time of computation). A 'supra-thermal' tail (with the deuterium ion energy higher than 10 keV) forms slowly at the ion distribution function; this tail determines a substantial part of the total neutron yield. The formation of stable vortices, which actually determine the structure of the plasma flow during the developed non-hydrodynamic stage of the plasma focus, is also found in the computations. These properties of the development of the sausage instability, as found in the numerical experiment with the MKHD plasma focus model, are in qualitative agreement with the behaviour of an instability of the same type in the MHD models of the Z-pinch

    Full Text Available A comparative analysis of selected short stories in the Balkan countries, as well as contemporary short stories of the world, will show us that the key themes of those stories are very similar to the short stories written during the period of transition in Bosnia and Herzegovina (1995-2010. For example, the story of the Soul Operation by an Iranian writer Mohsen Mahmalbafa, The Falcons by a Dutch writer Kader Abdolaha and On the Kitchen Stairs by a Polish writer Witold Gombrowic zinter connect with short stories by authors from Bosnia and Herzegovina, such as The Secret of Raspberry jam by Karim Zaimović or The Devilish work of Zoran Riđanović. A common thread manifests itself in the aforementioned stories, more specifically, a common theme which focuses on the need for eradication of the seeds of submission and compliance with the political system. Most authors focus on their domestic political systems; however, some portray and analyze systems in other countries as they see it, such as a Dutch narrator who focuses on a potential threat of infringement of human freedom. Moreover, Bellow Hubei by an Argentinian writer Anhelika Gorodis her underlines the importance of humanization within a political order. Faruk Šehić examines the political system in Bosnia and Herzegovina from a slightly different perspective. His collection of stories Under Pressure emphases the issue of pressure in the above war model of short stories in Bosnia and Herzegovina. These stories are the product of pressure and anxiety, with intent to latently promote new ways of spiritual survival, directly relating to the concept and the theme of the story The Past Age Man by Christian Karlson Stead. Further analysis of the alienation theme singled out short stories in Bosnia and Herzegovina, Plants are Something Else by Alma Lazarevska and Dialogues by Lamija Begagić, and pointed out their connection with some recent international short stories such as The Last Defence by

    Plasma Focus(PF) Devices are thermonuclear pulsators that produce short pulsed radiation (X-ray, charged particles and neutrons). Since Filippov and Mather, investigations have been used to study plasma properties. Nowadays the interest about PF is focused in technology applications, related to the use of these devices as pulsed neutron sources. In the numerical calculus the Inter institutional PLADEMA (PLAsmas DEnsos MAgnetizados) network is developing three models. Each one is useful in different engineering stages of the Plasma Focus design. One of the main objectives in this work is a comparative study on the influence of the different parameters involved in each models. To validate these results, several experimental measurements under different geometry and initial conditions were performed. (author)

  1. The Time Is Right to Focus on Model Organism Metabolomes

    Directory of Open Access Journals (Sweden)

    Arthur S. Edison

    2016-02-01

    Full Text Available Model organisms are an essential component of biological and biomedical research that can be used to study specific biological processes. These organisms are in part selected for facile experimental study. However, just as importantly, intensive study of a small number of model organisms yields important synergies as discoveries in one area of science for a given organism shed light on biological processes in other areas, even for other organisms. Furthermore, the extensive knowledge bases compiled for each model organism enable systems-level understandings of these species, which enhance the overall biological and biomedical knowledge for all organisms, including humans. Building upon extensive genomics research, we argue that the time is now right to focus intensively on model organism metabolomes. We propose a grand challenge for metabolomics studies of model organisms: to identify and map all metabolites onto metabolic pathways, to develop quantitative metabolic models for model organisms, and to relate organism metabolic pathways within the context of evolutionary metabolomics, i.e., phylometabolomics. These efforts should focus on a series of established model organisms in microbial, animal and plant research.

  2. Modeling the Evolution of Beliefs Using an Attentional Focus Mechanism.

    Full Text Available For making decisions in everyday life we often have first to infer the set of environmental features that are relevant for the current task. Here we investigated the computational mechanisms underlying the evolution of beliefs about the relevance of environmental features in a dynamical and noisy environment. For this purpose we designed a probabilistic Wisconsin card sorting task (WCST with belief solicitation, in which subjects were presented with stimuli composed of multiple visual features. At each moment in time a particular feature was relevant for obtaining reward, and participants had to infer which feature was relevant and report their beliefs accordingly. To test the hypothesis that attentional focus modulates the belief update process, we derived and fitted several probabilistic and non-probabilistic behavioral models, which either incorporate a dynamical model of attentional focus, in the form of a hierarchical winner-take-all neuronal network, or a diffusive model, without attention-like features. We used Bayesian model selection to identify the most likely generative model of subjects' behavior and found that attention-like features in the behavioral model are essential for explaining subjects' responses. Furthermore, we demonstrate a method for integrating both connectionist and Bayesian models of decision making within a single framework that allowed us to infer hidden belief processes of human subjects.

    Full Text Available Modern multicultural society and is a dynamic life marked by interaction between the components of a diverse society based on the rule of science and technology. A society that is increasingly complex due to the rapid changes in various aspects of life often creates problems for the individual's life. For example, inner tension, internal and external conflicts, and emotional disturbance. Facing these challenges, the individual is expected to have resilience was good. The role of the counselor is to help the counselee improve resilience with counseling approach effectively. Counseling models that meet the criteria of an effective and efficient is the Solution Focused Brief Counseling. Counseling model emphasizes the collaborative process between counselor and counselee to find solutions to achieve the expected goals. In the process of this counseling model uses questioning techniques to uncover the story, advantages, strengths and exceptions problems experienced by counselee in a short time.

    Today, developments of Real Time Embedded Systems have to face new challenges. On the one hand, Time-To-Market constraints require a reliable development process allowing quick design space exploration. On the other hand, rapidly developing technology, as stated by Moore's law, requires techniques to handle the resulting productivity gap. In a previous paper, we have presented our Model Based Engineering methodology addressing those issues. In this paper, we make a focus on Models of Computation design and analysis. We illustrate our approach on a Cognitive Radio System development implemented on an FPGA. This work is part of the MoPCoM research project gathering academic and industrial organizations (http://www.mopcom.fr).

    Full Text Available The process of effectively applying techniques for fostering creativity in educational settings is – by nature – multifaceted and not straightforward, as it pertains to several fields such as cognitive theory and psychology. Furthermore, the quantification of the impact of different activities on creativity is a challenging and not yet thoroughly investigated task. In this paper, we present the process of applying the Semantic Lateral Thinking technique for fostering creativity in Creative Stories, a digital storytelling game, via the introduction of the appropriate stimuli in the game’s flow. Furthermore, we present a formalization for a person’s creativity as a derivative of his/her creations within the game, by transitioning from traditional computational creativity metrics over the produced stories to a space that adheres to the core principles of creativity as perceived by humans.

  15. Understanding Science: Frameworks for using stories to facilitate systems thinking

    Science.gov (United States)

    ElShafie, S. J.; Bean, J. R.

    2017-12-01

    Studies indicate that using a narrative structure for teaching and learning helps audiences to process and recall new information. Stories also help audiences retain specific information, such as character names or plot points, in the context of a broader narrative. Stories can therefore facilitate high-context systems learning in addition to low-context declarative learning. Here we incorporate a framework for science storytelling, which we use in communication workshops, with the Understanding Science framework developed by the UC Museum of Paleontology (UCMP) to explore the application of storytelling to systems thinking. We translate portions of the Understanding Science flowchart into narrative terms. Placed side by side, the two charts illustrate the parallels between the scientific process and the story development process. They offer a roadmap for developing stories about scientific studies and concepts. We also created a series of worksheets for use with the flowcharts. These new tools can generate stories from any perspective, including a scientist conducting a study; a character that plays a role in a larger system (e.g., foraminifera or a carbon atom); an entire system that interacts with other systems (e.g., the carbon cycle). We will discuss exemplar stories about climate change from each of these perspectives, which we are developing for workshops using content and storyboard models from the new UCMP website Understanding Global Change. This conceptual framework and toolkit will help instructors to develop stories about scientific concepts for use in a classroom setting. It will also help students to analyze stories presented in class, and to create their own stories about new concepts. This approach facilitates student metacognition of the learning process, and can also be used as a form of evaluation. We are testing this flowchart and its use in systems teaching with focus groups, in preparation for use in teacher professional development workshops.

  17. The framework of studying personal and family stories

    Directory of Open Access Journals (Sweden)

    Dragana Antonijević

    2016-02-01

    Full Text Available In this paper I suggest the analytical framework for interpreting personal and family stories about the loss of possessions, riches, job, reputation and status. I find the theoretic foothold in the decades long folkloristic and anthropological studies of personal stories and life histories, then in the concept by Gary Alan Fine, a sociologist and folklorist, about the idioculture of small groups through the discussion of the family folklore, and last in the discussion of the historic, social-economic and ideological context where personal and family losses occur. The incentive for me to deal with this type of stories resides in the fact that they have not been the subject of scientific analysis, neither in the world, nor in our country, except one work by an American folklorist Stanley Brandes from 1975, which served as my inspiration and model. The material for the analysis was collected in the form of term papers written by four generations of ethnology and anthropology third year students, attending the course in Folklore anthropology at the Ethnology and Anthropology Department of the Faculty of Philosophy of Belgrade University. A typology of these stories has been done, and they are divided into two groups with subtypes: stories about personal causes to material ruin, and about faith (destiny causing the ruin. Further on in the analysis I focused only on the context of the stories with the so-called "pre-destined (faith" causes of ruin, i.e., on the historic, social-economic and ideological changes in Serbia, which happened during the 20th and at the beginning of the 21st century. The context of the revolutionary takeover of power by the Communists after the World War Two is discussed, as well as the violent dispossession of what was until then private property of many families in Serbia, and transferring that property into state and social possession (the so-called stories about nationalization, and also the specific context of post

    There occurred a moderate size earthquake of M=5 at Whagae-Myun, Hadong-Gun, Kyongsangnam-Do of Korea. It caused severe damage to the buildings and other structures in Sang-Gye-Sa, a famous and beautiful Buddhist Temple. The 5-story stone pagoda was standing in front of Keumdang. The top component tipped over and fell to the ground during the earthquake. In order to have accurate and quantitative estimate of the intensity of earthquake, a full-scale replica is made through rigorous verification process. The completed model was mounted on the shaking table and subjected to the seismic tests. It was observed that the top component overturned at 0.16 G of EPGA when the NS component of the 1940 El Centro earthquake records was used as the input motion. A brief history of this project is presented and important test results are reported and their implication is discussed

    Whilst high-resolution spatial variables contribute to a good fit of spatially explicit deforestation models, socio-economic processes are often beyond the scope of these models. Such a low level of interest in the socio-economic dimension of deforestation limits the relevancy of these models for decision-making and may be the cause of their failure to accurately predict observed deforestation trends in the medium term. This study aims to propose a flexible methodology for taking into account multiple drivers of deforestation in tropical forested areas, where the intensity of deforestation is explicitly predicted based on socio-economic variables. By coupling a model of deforestation location based on spatial environmental variables with several sub-models of deforestation intensity based on socio-economic variables, we were able to create a map of predicted deforestation over the period 2001-2014 in French Guiana. This map was compared to a reference map for accuracy assessment, not only at the pixel scale but also over cells ranging from 1 to approximately 600 sq. km. Highly significant relationships were explicitly established between deforestation intensity and several socio-economic variables: population growth, the amount of agricultural subsidies, gold and wood production. Such a precise characterization of socio-economic processes allows to avoid overestimation biases in high deforestation areas, suggesting a better integration of socio-economic processes in the models. Whilst considering deforestation as a purely geographical process contributes to the creation of conservative models unable to effectively assess changes in the socio-economic and political contexts influencing deforestation trends, this explicit characterization of the socio-economic dimension of deforestation is critical for the creation of deforestation scenarios in REDD+ projects. © 2017 John Wiley & Sons Ltd.

  10. Sleep and Obesity: A focus on animal models

    2012-01-01

    The rapid rise in obesity prevalence in the modern world parallels a significant reduction in restorative sleep (Agras et al., 2004; Dixon et al., 2007; Dixon et al., 2001; Gangwisch and Heymsfield, 2004; Gupta et al., 2002; Sekine et al., 2002; Vioque et al., 2000; Wolk et al., 2003). Reduced sleep time and quality increases the risk for obesity, but the underlying mechanisms remain unclear (Gangwisch et al., 2005; Hicks et al., 1986; Imaki et al., 2002; Jennings et al., 2007; Moreno et al., 2006). A majority of the theories linking human sleep disturbances and obesity rely on self-reported sleep. However, studies with objective measurements of sleep/wake parameters suggest a U-shaped relationship between sleep and obesity. Studies in animal models are needed to improve our understanding of the association between sleep disturbances and obesity. Genetic and experimenter-induced models mimicking characteristics of human obesity are now available and these animal models will be useful in understanding whether sleep disturbances determine propensity for obesity, or result from obesity. These models exhibit weight gain profiles consistently different from control animals. Thus a careful evaluation of animal models will provide insight into the relationship between sleep disturbances and obesity in humans. In this review we first briefly consider the fundamentals of sleep and key sleep disturbances, such as sleep fragmentation and excessive daytime sleepiness (EDS), observed in obese individuals. Then we consider sleep deprivation studies and the role of circadian alterations in obesity. We describe sleep/wake changes in various rodent models of obesity and obesity resistance. Finally, we discuss possible mechanisms linking sleep disturbances with obesity. PMID:22266350

    2014-12-01

    Full Text Available The article focuses on border crossings in travel stories, which were published in hand-written newspapers in 19th- and early 20th-century Finland. These papers were a popular tradition in student organizations and popular movements. Border crossings appear in travel stories in three different representations. Firstly, border crossings are repeated motifs in travel stories, both as challenging events and as small gestures and encounters. Travel stories demarcate boundaries, but they also provide a means for transgressing them. Secondly, hand-written newspapers as a literary practice highlight borders between oral and written communication. They were produced as one single manuscript copy, and published by being read out aloud in social events. Thirdly, the authors of hand-written newspapers were placed on the border of different positions in society such as class, gender and age. My analysis is based on the methodological discussion of small stories and personal experience narratives; travel stories can be defined as "local event narratives". I have outlined four basic models for travel stories which emerge from hand-written newspapers: the great mission story, the grand tour story, the flaneur story and the retreat story. The analysis of travel stories is presented through four different case studies with a time range from the 1850s to the 1920s: these materials have been produced in two provincial student fraternities (osakunta, in the temperance society "Star" in Helsinki in the 1890s, and in the Social Democratic Youth Club in the small industrial town of Karkkila in the 1910s and the 1920s. Many parallel features can be observed in travel stories, even though the social background and ideology of the authors are quite different. Time and space are important aspects in travel stories, and they often demarcate boundaries of class and gender.

    The classic moral stories have been used extensively to teach children about the consequences of lying and the virtue of honesty. Despite their widespread use, there is no evidence whether these stories actually promote honesty in children. This study compared the effectiveness of four classic moral stories in promoting honesty in 3- to 7-year-olds. Surprisingly, the stories of "Pinocchio" and "The Boy Who Cried Wolf" failed to reduce lying in children. In contrast, the apocryphal story of "George Washington and the Cherry Tree" significantly increased truth telling. Further results suggest that the reason for the difference in honesty-promoting effectiveness between the "George Washington" story and the other stories was that the former emphasizes the positive consequences of honesty, whereas the latter focus on the negative consequences of dishonesty. When the "George Washington" story was altered to focus on the negative consequences of dishonesty, it too failed to promote honesty in children. © The Author(s) 2014.

    information available at that time, based on statements that appear in the SRES itself. The CIB method is a technique for constructing internally consistent qualitative scenarios. Global-scale scenario exercises, in particular climate scenarios, typically include both qualitative (narrative) and quantitative (model) elements. As noted by Schweizer and Kriegler, the dominant method for such studies, which Alcamo (2001, 2008) formalized and named the 'story and simulation' (SAS) approach, relies at least in part on quantitative modeling to ensure consistency. Schweizer and Kriegler rightly criticize the idea that models alone can ensure consistency of a scenario narrative. By itself, this critique is not new. Indeed, if asked, both Alcamo and Raskin et al (Raskin et al 2005), whom Schweizer and Kriegler (2012) cite, would probably agree with them; both sources emphasize the need for qualitative storylines that go beyond what models can provide. However, Schweizer and Kriegler correctly point out that these sources provide little or no guidance to those responsible for the narratives beyond a dialog with the model outputs. The CIB method addresses this problem, and Schweizer and Kriegler's application of the method shows that even the best narrative-writing teams can benefit from this guidance. While the paper of Schweizer and Kriegler makes a compelling argument for using CIB in global scenarios, it should be used in combination with other methods. A scenario exercise has several aims, of which consistency is one. Another important goal is diversity: given a set of internally consistent scenarios, a diverse set covers the space of possibilities, and thereby helps users of the scenarios avoid underestimating or overestimating the potential for change in one or another key factor (e.g., see (Carlsen 2009)). From this point of view, the SRES authors could legitimately respond to Schweizer and Kriegler's finding that the SRES scenarios excluded interesting variants on coal

    Older adults sometimes exhibit higher levels of off-target verbosity during story recall than do young adults. This appears as the inclusion of extraneous information not directly relevant to the topic. Some production of such material has been clearly related to cognitive decline, particularly older adults’ inability to inhibit production of irrelevant information. In tandem, however, research also suggests that some extraneous information is indirectly related to the topic and may reflect age differences in communicative styles. To further elucidate the social cognitive aspect of this issue, the question of import is: What is the content of the additional information provided by participants during story recall? The present study answers this question. Grounded in the autobiographical memory and life story literatures, we introduce the construct, story asides, and a reliable content-analytic scheme for its assessment. Young and older adults (N = 129) recalled one of two types of stories: a personal autobiographical memory or an experimenter-generated fictional story. Narratives were reliably coded for story asides. As expected, older adults produced more story asides than young adults only for autobiographical stories. The discussion focuses on the role of story asides in everyday communication including the possibility that they may be a sign of communicative expertise. PMID:26751005

  9. Telling Feminist Stories

    2009-01-01

    Full Text Available This article identifies and analyses the dominant stories that academics tell about the development of Western second wave feminist theory. Through an examination of recent production of interdisciplinary feminist and cultural theory journals, I suggest that despite a rhetorical insistence on multiple feminisms, Western feminist trajectories emerge as startlingly singular. In particular, I am critical of an insistent narrative that sees the development of feminist thought as a relentless march of progress or loss. This dominant approach oversimplifies the complex history of Western feminisms, fixes writers and perspectives within a particular decade, and repeatedly (and erroneously positions poststructuralist feminists as ‘the first’ to challenge the category ‘woman’ as the subject and object of feminist knowledge. Rather than provide a corrective history of Western feminist theory, the article interrogates the techniques through which this dominant story is secured, despite the fact that we (feminist theorists know better. My focus, therefore, is on citation patterns, discursive framings and some of their textual, theoretical and political effects. As an alternative, I suggest a realignment of key theorists purported to provide a critical break in feminist theory with their feminist citational traces, to force a concomitant re-imagining of our historical legacy and our place within it.

  11. Incorporation of ice sheet models into an Earth system model: Focus on methodology of coupling

    2018-03-01

    Elaboration of a modern Earth system model (ESM) requires incorporation of ice sheet dynamics. Coupling of an ice sheet model (ICM) to an AOGCM is complicated by essential differences in spatial and temporal scales of cryospheric, atmospheric and oceanic components. To overcome this difficulty, we apply two different approaches for the incorporation of ice sheets into an ESM. Coupling of the Antarctic ice sheet model (AISM) to the AOGCM is accomplished via using procedures of resampling, interpolation and assigning to the AISM grid points annually averaged meanings of air surface temperature and precipitation fields generated by the AOGCM. Surface melting, which takes place mainly on the margins of the Antarctic peninsula and on ice shelves fringing the continent, is currently ignored. AISM returns anomalies of surface topography back to the AOGCM. To couple the Greenland ice sheet model (GrISM) to the AOGCM, we use a simple buffer energy- and water-balance model (EWBM-G) to account for orographically-driven precipitation and other sub-grid AOGCM-generated quantities. The output of the EWBM-G consists of surface mass balance and air surface temperature to force the GrISM, and freshwater run-off to force thermohaline circulation in the oceanic block of the AOGCM. Because of a rather complex coupling procedure of GrIS compared to AIS, the paper mostly focuses on Greenland.

    In this paper, we developed a pinhole ring diffraction model for the focusing analysis of a large photon sieve. Instead of analyzing individual pinholes, we discuss the focusing of all of the pinholes in a single ring. An explicit equation for the diffracted field of individual pinhole ring has been proposed. We investigated the validity range of this generalized model and analytically describe the sufficient conditions for the validity of this pinhole ring diffraction model. A practical example and investigation reveals the high accuracy of the pinhole ring diffraction model. This simulation method could be used for fast and accurate focusing analysis of a large photon sieve.

  16. Simultaneously uncovering the patterns of brain regions involved in different story reading subprocesses.

    Directory of Open Access Journals (Sweden)

    Leila Wehbe

    Full Text Available Story understanding involves many perceptual and cognitive subprocesses, from perceiving individual words, to parsing sentences, to understanding the relationships among the story characters. We present an integrated computational model of reading that incorporates these and additional subprocesses, simultaneously discovering their fMRI signatures. Our model predicts the fMRI activity associated with reading arbitrary text passages, well enough to distinguish which of two story segments is being read with 74% accuracy. This approach is the first to simultaneously track diverse reading subprocesses during complex story processing and predict the detailed neural representation of diverse story features, ranging from visual word properties to the mention of different story characters and different actions they perform. We construct brain representation maps that replicate many results from a wide range of classical studies that focus each on one aspect of language processing and offer new insights on which type of information is processed by different areas involved in language processing. Additionally, this approach is promising for studying individual differences: it can be used to create single subject maps that may potentially be used to measure reading comprehension and diagnose reading disorders.

    2009-09-01

    Full Text Available Short story has recently become the focus of attention in the late decades in Iran. The expanding value of writing short story is actually a reasonable outcome of the dominance of minimalism- a movement which is based upon simplicity and shortness. Minimalist writers, leaving out redundant features of narration, mainly focus on essentialities through applying a variety of techniques such as cuttings from the interesting moments of real life, evading introduction, applying inter-referents, choice of words, short stanzas and sentences and so on. Looking upon critic’s opinion about such a tendency over the past and present, this article will come up with a brief explanation of the properties of such stories. Finally a sample story “candles will never go dead” will be analyzed and discussed in the lights of such techniques.

In this model, the source boundary conditions of the Spheroidal Beam Equation (SBE for difference frequency wave excitation were studied. Propagation curves and beam patterns for difference frequency component of the acoustic field are compared with those obtained for Khokhlov-Zabolotskaya-Kuznetsov (KZK model. The results demonstrate that the focused parametric model of SBE is good valid for a large aperture angle in the strongly focused acoustic field. It is also investigated that high directivity and good focal ability with the decreasing of downshift ratio and the increasing of half-aperture angle for the focused parametric model of SBE.

    2017-06-01

    The Medicare Access and CHIP Reauthorization Act (MACRA) of 2015 describes alternative payment models (APMs) as new approaches to health care payment that incentivize higher quality and value. MACRA incentivizes increasing APM participation by all physician specialties over the coming years. Some APMs will be deemed Advanced APMs; clinicians who are a Qualifying Participant in an Advanced APM will receive substantial benefits under MACRA including an automatic 5% payment bonus, regardless of their performance and savings within the APM, and a larger payment rate increase beginning in 2026. Existing APMs are most relevant to primary care physicians, and opportunities for radiologists to participate in Advanced APMs fulfilling Qualified Participant requirements are limited. Physician-Focused Payment Models (PFPMs), as described in MACRA, are APMs that target physicians' Medicare payments based on quality and cost of physician services. PFPMs must address a new issue or specialty compared with existing APMs and will thus foster a more diverse range of APMs encompassing a wider range of specialties. The PFPM Technical Advisory Committee is a new independent agency that will review proposals for new PFPMs and provide recommendations to CMS regarding their approval. The PFPM Technical Advisory Committee comprises largely primary care physicians and health policy experts and is not required to consult clinical experts when reviewing new specialist-proposed PFPMs. As PFPMs provide a compelling opportunity for radiologists to demonstrate and be rewarded for their unique contributions toward patient care, radiologists should embrace this new model and actively partner with other stakeholders in developing radiology-relevant PFPMs. Copyright © 2016 American College of Radiology.

    Plasma focus devices (PFDs) are strong sources of fusion neutrons but the problem of which interactions are responsible for the fusion reactions is still open since neither of the proposed theoretical models has been confirmed experimentally. A model for the trajectories of the deuteron ions in a configuration of selfconsistent electromagnetic fields is proposed starting from an empirical plasma model which describes the plasma focus collapse and column phases. The proposed model is only electrodynamical under the assumption of a uniform current density and an infinite length of the plasma column, not taking into account the fluid characteristics of the plasma.

    2013-04-01

    Culture and employee-focused criteria are important factors for the success of any organization. These factors have to be aligned with the productivity initiatives in the organization in order to gear ahead for excellence. Therefore, this article investigated the impact of culture and employee-focused criteria on productivity in Higher Education Institutions (HEIs) in Malaysia using intangible indicators through core values. The hypothesized relationship was tested using Structural Equation Modeling (SEM) with the PLS estimation technique. 429 questionnaires were returned from the target population. The results of the modelling revealed that the PLS estimation confirmed all the hypotheses tested as in the hypothesized model. The results generally support significant relationships between culture values, employee-focused values and productivity-focused values. The study also confirmed the mediating role of employee-focused values for the relationship between culture values and productivity-focused values. In conclusion, the empirically validated results supported the adequacy of the hypothezised model of the impact of culture and employee-focused criteria on productivity in HEI through value-based indicators.

    The purpose of this study was to uncover the essence and meaning of healing through narrative accounts of holistic nurses, using a qualitative, descriptive design integrating narrative and story inquiry. Twenty-five stories were collected. Seven stories revealed personal healing and have been published in a prior article. Eighteen stories, the focus of this analysis, revealed healing of another. A hybrid method blending narrative and story guided the overall process for the study. Nine themes emerged describing healing of another within three story segments: The Call to Healing, The Experience of Healing, and Insights. The theme within The Call to the Healing Encounter was Drawn by Compassion to the Vulnerability and/or Suffering of Another. Five themes describe the Experience of Healing: Connection: Cocreating Relationships; Taking Risks and Dealing With Skeptical Colleagues; Use of Modalities and Actions as Tools in Developing Self as an Instrument of Healing; Profound, Ineffable Events; and Using Metaphor and Rituals to Describe Healing. Three themes describe Insights: Mutual Transformation, Change, and Reciprocity; Gratitude for the Healing Encounter; and Leaving a Legacy. The metastory, a reconstructed story created by the researchers, was the final phase of research synthesizing and demonstrating themes of healing of another. Results were compared to existing healing literature. © The Author(s) 2014.

  6. Historical short stories as nature of science instruction in secondary science classrooms: Science teachers' implementation and students' reactions

    Science.gov (United States)

    Reid-Smith, Jennifer Ann

    This study explores the use of historical short stories as nature of science (NOS) instruction in thirteen secondary science classes. The stories focus on the development of science ideas and include statements and questions to draw students' and teachers' attention to key NOS ideas and misconceptions. This study used mixed methods to examine how teachers implement the stories, factors influencing teachers' implementation, the impact on students' NOS understanding, students' interest in the stories and factors correlated with their interest. Teachers' implementation decisions were influenced by their NOS understanding, curricula, time constraints, perceptions of student ability and resistance, and student goals. Teachers implementing stories at a high-level of effectiveness were more likely to make instructional decisions to mitigate constraints from the school environment and students. High-level implementers frequently referred to their learning goals for students as a rationale for implementing the stories even when facing constraints. Teachers implementing at a low-level of effectiveness were more likely to express that constraints inhibited effective implementation. Teachers at all levels of implementation expressed concern regarding the length of the stories and time required to fully implement the stories. Additionally, teachers at all levels of implementation expressed a desire for additional resources regarding effective story implementation and reading strategies. Evidence exists that the stories can be used to improve students' NOS understanding. However, under what conditions the stories are effective is still unclear. Students reported finding the stories more interesting than textbook readings and many students enjoyed learning about scientists and the development of science idea. Students' interest in the stories is correlated with their attitudes towards reading, views of effective science learning, attributions of academic success, and interest in

    Diagnosis lies at the heart of general practice. Every day general practitioners (GPs) visit patients with a wide variety of complaints and concerns, with often minor but sometimes serious symptoms. General practice has many features which differentiate it from specialty care setting, but during the last four decades little attention was paid to clinical reasoning in general practice. Therefore, we aimed to critically review the clinical reasoning models with a focus on the clinical reasoning in general practice or clinical reasoning of general practitioners to find out to what extent the existing models explain the clinical reasoning specially in primary care and also identity the gaps of the model for use in primary care settings. A systematic search to find models of clinical reasoning were performed. To have more precision, we excluded the studies that focused on neurobiological aspects of reasoning, reasoning in disciplines other than medicine decision making or decision analysis on treatment or management plan. All the articles and documents were first scanned to see whether they include important relevant contents or any models. The selected studies which described a model of clinical reasoning in general practitioners or with a focus on general practice were then reviewed and appraisal or critics of other authors on these models were included. The reviewed documents on the model were synthesized. Six models of clinical reasoning were identified including hypothetic-deductive model, pattern recognition, a dual process diagnostic reasoning model, pathway for clinical reasoning, an integrative model of clinical reasoning, and model of diagnostic reasoning strategies in primary care. Only one model had specifically focused on general practitioners reasoning. A Model of clinical reasoning that included specific features of general practice to better help the general practitioners with the difficulties of clinical reasoning in this setting is needed.

  12. Focused information criterion and model averaging based on weighted composite quantile regression

    KAUST Repository

    Xu, Ganggang

    2013-08-13

    We study the focused information criterion and frequentist model averaging and their application to post-model-selection inference for weighted composite quantile regression (WCQR) in the context of the additive partial linear models. With the non-parametric functions approximated by polynomial splines, we show that, under certain conditions, the asymptotic distribution of the frequentist model averaging WCQR-estimator of a focused parameter is a non-linear mixture of normal distributions. This asymptotic distribution is used to construct confidence intervals that achieve the nominal coverage probability. With properly chosen weights, the focused information criterion based WCQR estimators are not only robust to outliers and non-normal residuals but also can achieve efficiency close to the maximum likelihood estimator, without assuming the true error distribution. Simulation studies and a real data analysis are used to illustrate the effectiveness of the proposed procedure. © 2013 Board of the Foundation of the Scandinavian Journal of Statistics..

    The small beam sizes at the interaction point of a X-band linear collider require mechanical stabilization of the final focus magnets at the nanometer level. While passive systems provide adequate performance at many potential sites, active mechanical stabilization is useful if the natural or cultural ground vibration is higher than expected. A mechanical model of a room temperature linear collider final focus magnet has been constructed and actively stabilized with an accelerometer based system.

    We introduce a general fractal lattice growth model, significantly expanding the application scope of the fractal in the realm of optics. This model can be applied to construct various kinds of fractal "lattices" and then to achieve the design of a great diversity of fractal vector optical fields (F-VOFs) combinating with various "bases". We also experimentally generate the F-VOFs and explore their universal focusing behaviors. Multiple focal spots can be flexibly enginnered, and the optical tweezers experiment validates the simulated tight focusing fields, which means that this model allows the diversity of the focal patterns to flexibly trap and manipulate micrometer-sized particles. Furthermore, the recovery performance of the F-VOFs is also studied when the input fields and spatial frequency spectrum are obstructed, and the results confirm the robustness of the F-VOFs in both focusing and imaging processes, which is very useful in information transmission.

    Full Text Available This paper develops model selection and averaging methods for moment restriction models. We first propose a focused information criterion based on the generalized empirical likelihood estimator. We address the issue of selecting an optimal model, rather than a correct model, for estimating a specific parameter of interest. Then, this study investigates a generalized empirical likelihood-based model averaging estimator that minimizes the asymptotic mean squared error. A simulation study suggests that our averaging estimator can be a useful alternative to existing post-selection estimators.

    A new model for plasma behaviour in Filippov type plasma focus (PF) systems has been described and used. This model is based on the so-called slug model and Sing Lee's model for Mather type PF devices. Using the model, the discharge current and its derivative as a function of time, and the pinch time and the maximum discharge current as a function of pressure, have been predicted. At the end, the predicted data are compared with the experimental data obtained through a Filippov type PF facility with a nominal maximum energy of 90 kJ

    The synchronization of loosely coupled chaotic systems has increasingly found applications to large networks of differential equations and to models of continuous media. These applications are at the core of the present Focus Issue. Synchronization between a system and its model, based on limited observations, gives a new perspective on data assimilation. Synchronization among different models of the same system defines a supermodel that can achieve partial consensus among models that otherwise disagree in several respects. Finally, novel methods of time series analysis permit a better description of synchronization in a system that is only observed partially and for a relatively short time. This Focus Issue discusses synchronization in extended systems or in components thereof, with particular attention to data assimilation, supermodeling, and their applications to various areas, from climate modeling to macroeconomics.

  4. Object selection costs in visual working memory: A diffusion model analysis of the focus of attention.

    Science.gov (United States)

    Sewell, David K; Lilburn, Simon D; Smith, Philip L

    2016-11-01

    A central question in working memory research concerns the degree to which information in working memory is accessible to other cognitive processes (e.g., decision-making). Theories assuming that the focus of attention can only store a single object at a time require the focus to orient to a target representation before further processing can occur. The need to orient the focus of attention implies that single-object accounts typically predict response time costs associated with object selection even when working memory is not full (i.e., memory load is less than 4 items). For other theories that assume storage of multiple items in the focus of attention, predictions depend on specific assumptions about the way resources are allocated among items held in the focus, and how this affects the time course of retrieval of items from the focus. These broad theoretical accounts have been difficult to distinguish because conventional analyses fail to separate components of empirical response times related to decision-making from components related to selection and retrieval processes associated with accessing information in working memory. To better distinguish these response time components from one another, we analyze data from a probed visual working memory task using extensions of the diffusion decision model. Analysis of model parameters revealed that increases in memory load resulted in (a) reductions in the quality of the underlying stimulus representations in a manner consistent with a sample size model of visual working memory capacity and (b) systematic increases in the time needed to selectively access a probed representation in memory. The results are consistent with single-object theories of the focus of attention. The results are also consistent with a subset of theories that assume a multiobject focus of attention in which resource allocation diminishes both the quality and accessibility of the underlying representations.

    2008-01-01

    From the basic energy conservation equations and experimental or empirical correlations, an intact model is constructed for the thermal calculation of the core debris in the lower plenum. For verification of this model, the results of two calculations for AP600 and AP1000 plants are compared with those presented in relevant literature. The analysis highlights on the impact of the decay heat power density and the focusing effect. In order to mitigate the focusing effect, it is proposed in this paper to change the lower head profile from hemisphere to parabola. The results show that this change of lower head profile can change the heat flux distribution of the debris, and mitigate the focusing effect. (authors)

    Acceleration of free electrons by the inverse Cherenkov effect using radially polarized laser light focused through an axicon [J. P. Fontana and R. H. Pantell, J. Appl. Phys. 54, 4285 (1983)] has been studied utilizing a Monte Carlo computer simulation and further theoretical analysis. The model includes effects, such as scattering of the electrons by the gas, and diffraction and interference effects of the axicon laser beam, that were not included in the original analysis of Fontana and Pantell. Its accuracy is validated using available experimental data. The model results show that effective acceleration is possible even with the effects of scattering. Sample results are given. The analysis includes examining the issues of axicon focusing, phase errors, energy gain, phase slippage, focusing of the e beam, and emittance growth

  8. Clients' and therapists' stories about psychotherapy.

    Science.gov (United States)

    Adler, Jonathan M

    2013-12-01

    This article provides an overview of the emerging field of research on clients' stories about their experiences in psychotherapy. The theory of narrative identity suggests that individuals construct stories about their lives in order to provide the self with a sense of purpose and unity. Psychotherapy stories serve both psychological functions. Focusing on the theme of agency as a vehicle for operationalizing purpose and coherence as a way of operationalizing unity, this article will describe the existing scholarship connecting psychotherapy stories to clients' psychological well-being. Results from cross-sectional qualitative and quantitative studies as well as longitudinal research indicate a connection between the stories clients tell about therapy and their psychological well-being, both over the course of treatment and after it is over. In addition, a preliminary analysis of therapists' stories about their clients' treatment is presented. These analyses reveal that the way therapists recount a particular client's therapy does not impact the relationships between clients' narratives and their improvement. The article concludes with a discussion of how this body of scholarship might be fruitfully applied in the realm of clinical practice. © 2012 Wiley Periodicals, Inc.

  9. Exploring How Usage-Focused Business Models Enable Circular Economy through Digital Technologies

    2018-02-01

    Full Text Available Recent studies advocate that digital technologies are key enabling factors for the introduction of servitized business models. At the same time, these technologies support the implementation of the circular economy (CE paradigm into businesses. Despite this general agreement, the literature still overlooks how digital technologies enable such a CE transition. To fill the gap, this paper develops a conceptual framework, based on the literature and a case study of a company implementing a usage-focused servitized business model in the household appliance industry. This study focuses on the Internet of Things (IoT, Big Data, and analytics, and identifies eight specific functionalities enabled by such technologies (improving product design, attracting target customers, monitoring and tracking product activity, providing technical support, providing preventive and predictive maintenance, optimizing the product usage, upgrading the product, enhancing renovation and end-of-life activities. By investigating how these functionalities affect three CE value drivers (increasing resource efficiency, extending lifespan, and closing the loop, the conceptual framework developed in this paper advances knowledge about the role of digital technologies as an enabler of the CE within usage-focused business models. Finally, this study shows how digital technologies help overcome the drawback of usage-focused business models for the adoption of CE pointed out by previous literature.

    2013-08-01

    A multiphysics computational model of the focusing of an acoustic pulse and subsequent shock wave formation that occurs during extracorporeal shock wave lithotripsy is presented. In the electromagnetic lithotripter modeled in this work the focusing is achieved via a polystyrene acoustic lens. The transition of the acoustic pulse through the solid lens is modeled by the linear elasticity equations and the subsequent shock wave formation in water is modeled by the Euler equations with a Tait equation of state. Both sets of equations are solved simultaneously in subsets of a single computational domain within the BEARCLAW framework which uses a finite-volume Riemann solver approach. This model is first validated against experimental measurements with a standard (or original) lens design. The model is then used to successfully predict the effects of a lens modification in the form of an annular ring cut. A second model which includes a kidney stone simulant in the domain is also presented. Within the stone the linear elasticity equations incorporate a simple damage model.

    Sotiralis, P.; Ventikos, N.P.; Hamann, R.; Golyshev, P.; Teixeira, A.P.

    2016-01-01

    This paper presents an approach that more adequately incorporates human factor considerations into quantitative risk analysis of ship operation. The focus is on the collision accident category, which is one of the main risk contributors in ship operation. The approach is based on the development of a Bayesian Network (BN) model that integrates elements from the Technique for Retrospective and Predictive Analysis of Cognitive Errors (TRACEr) and focuses on the calculation of the collision accident probability due to human error. The model takes into account the human performance in normal, abnormal and critical operational conditions and implements specific tasks derived from the analysis of the task errors leading to the collision accident category. A sensitivity analysis is performed to identify the most important contributors to human performance and ship collision. Finally, the model developed is applied to assess the collision risk of a feeder operating in Dover strait using the collision probability estimated by the developed BN model and an Event tree model for calculation of human, economic and environmental risks. - Highlights: • A collision risk model for the incorporation of human factors into quantitative risk analysis is proposed. • The model takes into account the human performance in different operational conditions leading to the collision. • The most important contributors to human performance and ship collision are identified. • The model developed is applied to assess the collision risk of a feeder operating in Dover strait.

    2009-01-01

    A theoretical model of the nonlinear propagation in multi-layered tissues for strong focused ultrasound is proposed. In this model, the spheroidal beam equation (SBE) is utilized to describe the nonlinear sound propagation in each layer tissue, and generalized oblique incidence theory is used to deal with the sound transmission between two layer tissues. Computer simulation is performed on a fat-muscle-liver tissue model under the irradiation of a 1 MHz focused transducer with a large aperture angle of 35°. The results demonstrate that the tissue layer would change the amplitude of sound pressure at the focal region and cause the increase of side petals.

  16. Suicide in the media: a quantitative review of studies based on non-fictional stories.

    Stack, Steven

    2005-04-01

    Research on the effect of suicide stories in the media on suicide in the real world has been marked by much debate and inconsistent findings. Recent narrative reviews have suggested that research based on nonfictional models is more apt to uncover imitative effects than research based on fictional models. There is, however, substantial variation in media effects within the research restricted to nonfictional accounts of suicide. The present analysis provides some explanations of the variation in findings in the work on nonfictional media. Logistic regression techniques applied to 419 findings from 55 studies determined that: (1) studies measuring the presence of either an entertainment or political celebrity were 5.27 times more likely to find a copycat effect, (2) studies focusing on stories that stressed negative definitions of suicide were 99% less likely to report a copycat effect, (3) research based on television stories (which receive less coverage than print stories) were 79% less likely to find a copycat effect, and (4) studies focusing on female suicide were 4.89 times more likely to report a copycat effect than other studies. The full logistic regression model correctly classified 77.3% of the findings from the 55 studies. Methodological differences among studies are associated with discrepancies in their results.

    2018-04-01

    Productivity improvement is posing a great challenge for industry everyday because of the difficulties in keeping track and priorising the variables that have significant impact on the productivity. The variation in production depends on the linguistic variables such as worker commitment, worker motivation and worker skills. Since the variables are linguistic we try to propose a model which gives an appropriate production of an industry. Fuzzy models aids the relationship between the factors and status. The model will support the industry to focus on the mentality of worker to increase the production.

    The aim of current efforts in the European area is the protection of soil organic matter, which is included in all relevant documents related to the protection of soil. The use of modelling of organic carbon stocks for anticipated climate change, respectively for land management can significantly help in short and long-term forecasting of the state of soil organic matter. RothC model can be applied in the time period of several years to centuries and has been tested in long-term experiments within a large range of soil types and climatic conditions in Europe. For the initialization of the RothC model, knowledge about the carbon pool sizes is essential. Pool size characterization can be obtained from equilibrium model runs, but this approach is time consuming and tedious, especially for larger scale simulations. Due to this complexity we search for new possibilities how to simplify and accelerate this process. The paper presents a comparison of two approaches for SOC stocks modelling in the same area. The modelling has been carried out on the basis of unique input of land use, management and soil data for each simulation unit separately. We modeled 1617 simulation units of 1x1 km grid on the territory of agroclimatic region Žitný ostrov in the southwest of Slovakia. The first approach represents the creation of groups of simulation units based on the evaluation of results for simulation unit with similar input values. The groups were created after the testing and validation of modelling results for individual simulation units with results of modelling the average values of inputs for the whole group. Tests of equilibrium model for interval in the range 5 t.ha-1 from initial SOC stock showed minimal differences in results comparing with result for average value of whole interval. Management inputs data from plant residues and farmyard manure for modelling of carbon turnover were also the same for more simulation units. Combining these groups (intervals of initial

  9. Multi-relaxation-time lattice Boltzmann modeling of the acoustic field generated by focused transducer

    Shan, Feng; Guo, Xiasheng; Tu, Juan; Cheng, Jianchun; Zhang, Dong

    The high-intensity focused ultrasound (HIFU) has become an attractive therapeutic tool for the noninvasive tumor treatment. The ultrasonic transducer is the key component in HIFU treatment to generate the HIFU energy. The dimension of focal region generated by the transducer is closely relevant to the safety of HIFU treatment. Therefore, it is essential to numerically investigate the focal region of the transducer. Although the conventional acoustic wave equations have been used successfully to describe the acoustic field, there still exist some inherent drawbacks. In this work, we presented an axisymmetric isothermal multi-relaxation-time lattice Boltzmann method (MRT-LBM) model with the Bouzidi-Firdaouss-Lallemand (BFL) boundary condition in cylindrical coordinate system. With this model, some preliminary simulations were firstly conducted to determine a reasonable value of the relaxation parameter. Then, the validity of the model was examined by comparing the results obtained with the LBM results with the Khokhlov-Zabolotskaya-Kuznetsov (KZK) equation and the Spheroidal beam equation (SBE) for the focused transducers with different aperture angles, respectively. In addition, the influences of the aperture angle on the focal region were investigated. The proposed model in this work will provide significant references for the parameter optimization of the focused transducer for applications in the HIFU treatment or other fields, and provide new insights into the conventional acoustic numerical simulations.

    2006-01-01

    A growth model for accumulating seismic energy in a localized seismic focus is described, which introduces a fractional parameter r on geometrical grounds. The model is employed for deriving a power-type law for the statistical distribution in energy, where the parameter r contributes to the exponent, as well as corresponding time and magnitude distributions for earthquakes. The accompanying seismic activity of foreshocks and aftershocks is discussed in connection with this approach, as based on Omori distributions, and the rate of released energy is derived

  12. An auto-focusing heuristic model to increase the reliability of a scientific mission

    International Nuclear Information System (INIS)

    2006-01-01

    Researchers invest a lot of time and effort on the design and development of components used in a scientific mission. To capitalize on this investment and on the operational experience of the researchers, it is useful to adopt a quantitative data base to monitor the history and usage of the components. This work describes a model to monitor the reliability level of components. The model is very flexible and allows users to compose systems using the same components in different configurations as required by each mission. This tool provides availability and reliability figures for the configuration requested, derived from historical data of the components' previous performance. The system is based on preliminary checklists to establish standard operating procedures (SOP) for all components life phases. When an infringement to the SOP occurs, a quantitative ranking is provided in order to quantify the risk associated with this deviation. The final agreement between field data and expected performance of the component makes the model converge onto a heuristic monitoring system. The model automatically focuses on points of failure at the detailed component element level, calculates risks, provides alerts when a demonstrated risk to safety is encountered, and advises when there is a mismatch between component performance and mission requirements. This model also helps the mission to focus resources on critical tasks where they are most needed

    Vatcher, C A; Bogo, M

    2001-01-01

    Emotionally focused therapy (EFT) is a well-developed, empirically tested practice model for couple therapy that integrates systems, experiential, and attachment theories. Feminist family therapy theory has provided a critique of biased assumptions about gender at play in traditional family therapy practice and the historical absence of discussions of power in family therapy theory. This article presents an integrated feminist/EFT practice model for use in couple therapy, using a case from practice to illustrate key concepts. Broadly, the integrated model addresses gender roles and individual emotional experience using a systemic framework for understanding couple interaction. The model provides practitioners with a sophisticated, comprehensive, and relevant practice approach for working with the issues and challenges emerging for contemporary heterosexual couples.

  16. The transition from diffuse to focused extension: Modeled evolution of the West Antarctic Rift system

    Science.gov (United States)

    Huerta, Audrey D.; Harry, Dennis L.

    2007-03-01

    Two distinct stages of extension are recognized in the West Antarctic Rift system (WARS). During the first stage, beginning in the Late Cretaceous, extension was broadly distributed throughout much of West Antarctica. A second stage of extension in the late Paleogene was focused primarily in the Victoria Land Basin, near the boundary with the East Antarctic craton. The transition to focused extension was roughly coeval with volcanic activity and strike-slip faulting in the adjacent Transantarctic Mountains. This spatial and temporal correspondence suggests that the transition in extensional style could be the result of a change in plate motions or impingement of a plume. Here we use finite element models to study the processes and conditions responsible for the two-stage evolution of rifting in the WARS. Model results indicate that the transition from a prolonged period of broadly distributed extension to a later period of focused rifting did not require a change in the regional stress regime (changes in plate motion), or deep mantle thermal state (impingement of a plume). Instead, we attribute the transition from diffuse to focused extension to an early stage dominated by the initially weak accreted lithosphere of West Antarctica, and a later stage that concentrated around a secondary weakness located at the boundary between the juvenile West Antarctica lithosphere and Precambrian East Antarctic craton. The modeled transition in extension from the initially weak West Antarctica region to the secondary weakness at the West Antarctic-East Antarctic boundary is precipitated by strengthening of the West Antarctica lithosphere during syn-extensional thinning and cooling. The modeled syn-extensional strengthening of the WARS lithosphere promotes a wide-rift mode of extension between 105 and ˜ 65 Ma. By ˜ 65 Ma most of the extending WARS region becomes stronger than the area immediately adjacent to the East Antarctic craton and extension becomes concentrated near the

    2008-01-01

    Full Text Available It is well known that focused ultrasound has a biologic effect on tissue. High intensity focused ultrasound (HIFU on a small target area raises the temperature of the tissue enough to denaturate proteins and cause irreversible cell damage. The tight focus of the ultrasound energy allows delivery of the intended dose to a very precise location. The resulting coagulation necrosis is relatively painless. The application of this method in the human clinical setting has required pilot studies on an animal model. Although the treatment had a high success rate, there was a significant percentage of complications, mainly attributed to the technical drawbacks of the procedure. Therefore, this method has been modified for use in humans, and the HIFU is now guided, monitored and controlled by magnetic resonance imaging (MRI. In October 2004, Food and Drug Adiministration (FDA approved MRI guided focused ultrasound treatment of uterine fibroids in humans. Since then, successful treatment of uterine myomas by HIFU has been performed in thousands of women.

  18. Modeling of Focused Acoustic Field of a Concave Multi-annular Phased Array Using Spheroidal Beam Equation

    Yu, Li-Li; Shou, Wen-De; Hui, Chun

    2012-02-01

    A theoretical model of focused acoustic field for a multi-annular phased array on concave spherical surface is proposed. In this model, the source boundary conditions of the spheroidal beam equation (SBE) for multi-annular phased elements are studied. Acoustic field calculated by the dynamic focusing model of SBE is compared with numerical results of the O'Neil and Khokhlov—Zabolotskaya—Kuznetsov (KZK) model, respectively. Axial dynamic focusing and the harmonic effects are presented. The results demonstrate that the dynamic focusing model of SBE is good valid for a concave multi-annular phased array with a large aperture angle in the linear or nonlinear field.

    Souza, Alessandra S; Rerko, Laura; Lin, Hsuan-Yu; Oberauer, Klaus

    2014-10-01

    Performance in working memory (WM) tasks depends on the capacity for storing objects and on the allocation of attention to these objects. Here, we explored how capacity models need to be augmented to account for the benefit of focusing attention on the target of recall. Participants encoded six colored disks (Experiment 1) or a set of one to eight colored disks (Experiment 2) and were cued to recall the color of a target on a color wheel. In the no-delay condition, the recall-cue was presented after a 1,000-ms retention interval, and participants could report the retrieved color immediately. In the delay condition, the recall-cue was presented at the same time as in the no-delay condition, but the opportunity to report the color was delayed. During this delay, participants could focus attention exclusively on the target. Responses deviated less from the target's color in the delay than in the no-delay condition. Mixture modeling assigned this benefit to a reduction in guessing (Experiments 1 and 2) and transposition errors (Experiment 2). We tested several computational models implementing flexible or discrete capacity allocation, aiming to explain both the effect of set size, reflecting the limited capacity of WM, and the effect of delay, reflecting the role of attention to WM representations. Both models fit the data better when a spatially graded source of transposition error is added to its assumptions. The benefits of focusing attention could be explained by allocating to this object a higher proportion of the capacity to represent color.

    The purpose of this study was to uncover the nature, experiences, and meaning of personal healing for holistic nurses through their narrative accounts. The study employed a qualitative descriptive design with methods of narrative and story inquiry. Participants were nurse attendees at an American Holistic Nurses' Association conference who volunteered for the study. They were invited to share a story about healing self or another. Twenty-five stories were collected; seven were about personal healing, and these are the focus of this analysis. Data were analyzed using a hybrid approach from narrative and story inquiry methods. Eleven themes were clustered under three story segments. The themes within the Call to the Healing Encounter are the following: recognition of the need to resolve a personal or health crisis, knowledge of or engagement in self-care practices, and reliance on intuitive knowing. Themes under the Experience of Healing are the following: connections; profound sensations, perceptions, and events; awareness of the reciprocal nature of healing; inner resolution: forgiveness, awakening, and acceptance; use of multiple holistic approaches; and witnessing manifestations of healing. The themes for Insights are the following: gratitude and appreciation and ongoing journey. A metastory synthesizing the themes is presented, and findings are related to existing literature on healing.

Speakers included climate experts from both NASA and the National Oceanic and Atmospheric Administration (NOAA), who provided updates on climate model diagnostics and evaluation and remote sensing of the planet. Details of the next summer school will be posted here in due course.

  2. Electrographic waveform structure predicts laminar focus location in a model of temporal lobe seizures in vitro.

    Directory of Open Access Journals (Sweden)

    Christopher Adams

    Full Text Available Temporal lobe epilepsy is the most common form of partial-onset epilepsy and accounts for the majority of adult epilepsy cases in most countries. A critical role for the hippocampus (and to some extent amygdala in the pathology of these epilepsies is clear, with selective removal of these regions almost as effective as temporal lobectomy in reducing subsequent seizure risk. However, there is debate about whether hippocampus is 'victim' or 'perpetrator': The structure is ideally placed to 'broadcast' epileptiform activity to a great many other brain regions, but removal often leaves epileptiform events still occurring in cortex, particularly in adjacent areas, and recruitment of the hippocampus into seizure-like activity has been shown to be difficult in clinically-relevant models. Using a very simple model of acute epileptiform activity with known, single primary pathology (GABAA Receptor partial blockade, we track the onset and propagation of epileptiform events in hippocampus, parahippocampal areas and neocortex. In this model the hippocampus acts as a potential seizure focus for the majority of observed events. Events with hippocampal focus were far more readily propagated throughout parahippocampal areas and into neocortex than vice versa. The electrographic signature of events of hippocampal origin was significantly different to those of primary neocortical origin - a consequence of differential laminar activation. These data confirm the critical role of the hippocampus in epileptiform activity generation in the temporal lobe and suggest the morphology of non-invasive electrical recording of neocortical interictal events may be useful in confirming this role.

  4. Modeling a Miniaturized Scanning Electron Microscope Focusing Column - Lessons Learned in Electron Optics Simulation

    Science.gov (United States)

    Loyd, Jody; Gregory, Don; Gaskin, Jessica

    2016-01-01

    This presentation discusses work done to assess the design of a focusing column in a miniaturized Scanning Electron Microscope (SEM) developed at the NASA Marshall Space Flight Center (MSFC) for use in-situ on the Moon-in particular for mineralogical analysis. The MSFC beam column design uses purely electrostatic fields for focusing, because of the severe constraints on mass and electrical power consumption imposed by the goals of lunar exploration and of spaceflight in general. The resolution of an SEM ultimately depends on the size of the focused spot of the scanning beam probe, for which the stated goal here is a diameter of 10 nanometers. Optical aberrations are the main challenge to this performance goal, because they blur the ideal geometrical optical image of the electron source, effectively widening the ideal spot size of the beam probe. In the present work the optical aberrations of the mini SEM focusing column were assessed using direct tracing of non-paraxial rays, as opposed to mathematical estimates of aberrations based on paraxial ray-traces. The geometrical ray-tracing employed here is completely analogous to ray-tracing as conventionally understood in the realm of photon optics, with the major difference being that in electron optics the lens is simply a smoothly varying electric field in vacuum, formed by precisely machined electrodes. Ray-tracing in this context, therefore, relies upon a model of the electrostatic field inside the focusing column to provide the mathematical description of the "lens" being traced. This work relied fundamentally on the boundary element method (BEM) for this electric field model. In carrying out this research the authors discovered that higher accuracy in the field model was essential if aberrations were to be reliably assessed using direct ray-tracing. This led to some work in testing alternative techniques for modeling the electrostatic field. Ultimately, the necessary accuracy was attained using a BEM

    2015-01-01

    The tradition of storytelling is an integral part of Alaska Native cultures that continues to be a way of passing on knowledge. Using a story-based approach to share cancer education is grounded in Alaska Native traditions and people’s experiences and has the potential to positively impact cancer knowledge, understandings, and wellness choices. Community health workers (CHWs) in Alaska created a personal digital story as part of a 5-day, in-person cancer education course. To identify engaging elements of digital stories among Alaska Native people, one focus group was held in each of three different Alaska communities with a total of 29 adult participants. After viewing CHWs’ digital stories created during CHW cancer education courses, focus group participants commented verbally and in writing about cultural relevance, engaging elements, information learned, and intent to change health behavior. Digital stories were described by Alaska focus group participants as being culturally respectful, informational, inspiring, and motivational. Viewers shared that they liked digital stories because they were short (only 2–3 min); nondirective and not preachy; emotional, told as a personal story and not just facts and figures; and relevant, using photos that showed Alaskan places and people.

    To review rodent animal models of polycystic ovary syndrome (PCOS), with a focus on those associated with the metabolic syndrome and cardiovascular disease risk factors. Review. Rodent models of PCOS. Description and comparison of animal models. Comparison of animal models to clinical phenotypes of PCOS. Animals used to study PCOS include rodents, mice, rhesus monkeys, and ewes. Major methods to induce PCOS in these models include subcutaneous injection or implantation of androgens, estrogens, antiprogesterone, letrozole, prenatal exposure to excess androgens, and exposure to constant light. In addition, transgenic mice models and spontaneous PCOS-like rodent models have also been developed. Rodents are the most economical and widely used animals to study PCOS and ovarian dysfunction. The model chosen to study the development of PCOS and other metabolic parameters remains dependent on the specific etiologic hypotheses being investigated. Rodent models have been shown to demonstrate changes in insulin metabolism, with or without induction of hyperandrogenemia, and limited studies have investigated cardiometabolic risk factors for type 2 diabetes and cardiovascular disease. Given the clinical heterogeneity of PCOS, the utilization of different animal models may be the best approach to further our understanding of the pathophysiologic mechanisms associated with the early etiology of PCOS and cardiometabolic risk.

  8. A Critical Overview of Models of Reading Comprehension with a Focus on Cognitive Aspects

    Directory of Open Access Journals (Sweden)

    Mohammad Taghi Shahnazari

    2014-09-01

    Full Text Available Abstract Reading is a cognitive activity involving skills, strategies, attentional resources, knowledge resources and their integration. The reader’s role is to decode the written symbols to allow for the recovery of information from long-term memory to construct a plausible interpretation of the writer’s message. Various number of reading models have been proposed by researchers among which some focus on motivational and emotional aspects of reading. Others highlight the cognitive aspects of reading. In this study, the models characterizing reading in terms of cognitive aspects are revieweded, and different viewpoints on the reading process are described. This may help EFL/ESL teachers to improve their understanding of the reading process, update their perspectives on teaching reading tasks which in turn might result in more efficient learning by not putting too much cognitively demanding reading tasks on EFL/ESL learners.

  9. External circuit integration with electromagnetic particle in cell modeling of plasma focus devices

    International Nuclear Information System (INIS)

    Seng, Y. S.; Lee, P.; Rawat, R. S.

    2015-01-01

    The pinch performance of a plasma focus (PF) device is sensitive to the physical conditions of the breakdown phase. It is therefore essential to model and study the initial phase in order to optimize device performance. An external circuit is self consistently coupled to the electromagnetic particle in cell code to model the breakdown and initial lift phase of the United Nations University/International Centre for Theoretical Physics (UNU-ICTP) plasma focus device. Gas breakdown during the breakdown phase is simulated successfully, following a drop in the applied voltage across the device and a concurrent substantial rise in the circuit current. As a result, the plasma becomes magnetized, with the growing value of the magnetic field over time leading to the gradual lift off of the well formed current sheath into the axial acceleration phase. This lifting off, with simultaneous outward sheath motion along the anode and vertical cathode, and the strong magnetic fields in the current sheath region, was demonstrated in this work, and hence validates our method of coupling the external circuit to PF devices. Our method produces voltage waveforms that are qualitatively similar to the observed experimental voltage profiles of the UNU-ICTP device. Values of the mean electron energy before and after voltage breakdown turned out to be different, with the values after breakdown being much lower. In both cases, the electron energy density function turned out to be non-Maxwellian

  2. Drosophila as a Model for Human Diseases-Focus on Innate Immunity in Barrier Epithelia.

    Bergman, P; Seyedoleslami Esfahani, S; Engström, Y

    2017-01-01

    Epithelial immunity protects the host from harmful microbial invaders but also controls the beneficial microbiota on epithelial surfaces. When this delicate balance between pathogen and symbiont is disturbed, clinical disease often occurs, such as in inflammatory bowel disease, cystic fibrosis, or atopic dermatitis, which all can be in part linked to impairment of barrier epithelia. Many innate immune receptors, signaling pathways, and effector molecules are evolutionarily conserved between human and Drosophila. This review describes the current knowledge on Drosophila as a model for human diseases, with a special focus on innate immune-related disorders of the gut, lung, and skin. The discovery of antimicrobial peptides, the crucial role of Toll and Toll-like receptors, and the evolutionary conservation of signaling to the immune systems of both human and Drosophila are described in a historical perspective. Similarities and differences between human and Drosophila are discussed; current knowledge on receptors, signaling pathways, and effectors are reviewed, including antimicrobial peptides, reactive oxygen species, as well as autophagy. We also give examples of human diseases for which Drosophila appears to be a useful model. In addition, the limitations of the Drosophila model are mentioned. Finally, we propose areas for future research, which include using the Drosophila model for drug screening, as a validation tool for novel genetic mutations in humans and for exploratory research of microbiota-host interactions, with relevance for infection, wound healing, and cancer. © 2017 Elsevier Inc.

    Educational research uses narrative enquiry to gain and interpret people's experiences. Narrative analysis is used to organise and make sense of acquired narrative. 'Core story creation' is a way of managing raw data obtained from narrative interviews to construct stories for learning. To explain how core story creation can be used to construct stories from raw narratives obtained by interviewing parents about their neonatal experiences and then use these stories to educate learners. Core story creation involves reconfiguration of raw narratives. Reconfiguration includes listening to and rereading transcribed narratives, identifying elements of 'emplotment' and reordering these to form a constructed story. Thematic analysis is then performed on the story to draw out learning themes informed by the participants. Core story creation using emplotment is a strategy of narrative reconfiguration that produces stories which can be used to develop resources relating to person-centred education about the patient experience. Stories constructed from raw narratives in the context of constructivism can provide a medium or an 'end product' for use in learning resource development. This can then contribute to educating students or health professionals about patients' experiences. ©2018 RCN Publishing Company Ltd. All rights reserved.

    This study presents a systematic approach to analyze the flow diversion and flow focusing caused by the natural flow-barrier system in the unsaturated zone (UZ) of Yucca Mountain, Nevada, under ambient steady-state flow conditions. An existing analytical solution for analyzing capillary barrier in porous media has been extended to apply to the fractured porous rock. The new analytical solutions are used to identify the critical layers and to provide the guidance for generation of a proper three-dimensional (3-D), site-scale numerical grid. A large-scale 3-D numerical model (with more than a million grid blocks) has been developed with site-specific data to analyze the major flow patterns in the mountain. Our analyses show that large-scale lateral flow could take place in the UZ under ambient conditions, as a result of capillary barriers formed at the contacts of heterogeneous rock layers. This lateral flow runs generally toward the east (in the southern part) or southeast (in the northern part), which is consistent with the dip of the layer contacts. About 90 percent of the total lateral flow is found to be conducted by only a few critical rock layers. Faults that penetrate these rock layers act as vertical capillary barriers that stop the lateral flow. The combined effect of horizontal and vertical capillary barriers resulted in reduced percolation flow through repository horizon in general but focused downward flow along those penetrating faults. The model results were found to be consistent with the field water saturation. The findings of this study are consistent with a previously published two-dimensional (2-D) analysis and recent published modeling results using field-observed Cl-data

    Magnetic resonance-guided high intensity focused ultrasound (MR-HIFU) has been clinically shown to be effective for palliative pain management in patients suffering from skeletal metastasis. The underlying mechanism is supposed to be periosteal denervation caused by ablative temperatures reached through ultrasound heating of the cortex. The challenge is exact temperature control during sonication as MR-based thermometry approaches for bone tissue are currently not available. Thus, in contrast to the MR-HIFU ablation of soft tissue, a thermometry feedback to the HIFU is lacking, and the treatment of bone metastasis is entirely based on temperature information acquired in the soft tissue adjacent to the bone surface. However, heating of the adjacent tissue depends on the exact sonication protocol and requires extensive modelling to estimate the actual temperature of the cortex. Here we develop a computational model to calculate the spatial temperature evolution in bone and the adjacent tissue during sonication. First, a ray-tracing technique is used to compute the heat production in each spatial point serving as a source term for the second part, where the actual temperature is calculated as a function of space and time by solving the Pennes bio-heat equation. Importantly, our model includes shear waves that arise at the bone interface as well as all geometrical considerations of transducer and bone geometry. The model was compared with a theoretical approach based on the far field approximation and an MR-HIFU experiment using a bone phantom. Furthermore, we investigated the contribution of shear waves to the heat production and resulting temperatures in bone. The temperature evolution predicted by our model was in accordance with the far field approximation and agreed well with the experimental data obtained in phantoms. Our model allows the simulation of the HIFU treatments of bone metastasis in patients and can be extended to a planning tool prior to MR

    Role modelling by clinicians assists in development of medical students' professional competencies, values and attitudes. Three core characteristics of a positive role model include 1) clinical attributes, 2) teaching skills, and 3) personal qualities. This study was designed to explore medical students' perceptions of their bedside clinical tutors as role models during the first year of a medical program. The study was conducted with one cohort (n = 301) of students who had completed Year 1 of the Sydney Medical Program in 2013. A total of nine focus groups (n = 59) were conducted with medical students following completion of Year 1. Data were transcribed verbatim. Thematic analysis was used to code and categorise data into themes. Students identified both positive and negative characteristics and behaviour displayed by their clinical tutors. Characteristics and behaviour that students would like to emulate as medical practitioners in the future included: 1) Clinical attributes: a good knowledge base; articulate history taking skills; the ability to explain and demonstrate skills at the appropriate level for students; and empathy, respect and genuine compassion for patients. 2) Teaching skills: development of a rapport with students; provision of time towards the growth of students academically and professionally; provision of a positive learning environment; an understanding of the student curriculum and assessment requirements; immediate and useful feedback; and provision of patient interaction. 3) Personal qualities: respectful interprofessional staff interactions; preparedness for tutorials; demonstration of a passion for teaching; and demonstration of a passion for their career choice. Excellence in role modelling entails demonstration of excellent clinical care, teaching skills and personal characteristics. Our findings reinforce the important function of clinical bedside tutors as role models, which has implications for faculty development and

  11. SOLAR WIND CHARGE EXCHANGE EMISSION FROM THE HELIUM FOCUSING CONE: MODEL TO DATA COMPARISON

    A model for heliospheric solar wind charge exchange (SWCX) X-ray emission is applied to a series of XMM-Newton observations of the interplanetary focusing cone of interstellar helium. The X-ray data are from three coupled observations of the South Ecliptic Pole (SEP; to observe the cone) and the Hubble Deep Field-North (HDF-N, to monitor global variations of the SWCX emission due to variations in the solar wind (SW)) from the period 2003 November 24 to December 15. There is good qualitative agreement between the model predictions and the data, after the SEP data are corrected using the HDF-N data, with the maximum SWCX flux observed at an ecliptic longitude of ∼72 deg., consistent with the central longitude of the He cone. We observe a total excess of 2.1 ± 1.3 line unit (LU) in the O VII line and 2.0 ± 0.9 LU in the O VIII line. However, the SWCX emission model, which was adjusted for SW conditions appropriate for late 2003, predicts an excess from the He cone of only 0.5 LU and 0.2 LU, respectively, in the O VII and O VIII lines. We discuss the model to data comparison and provide possible explanations for the discrepancies. We also qualitatively re-examine our SWCX model predictions in the 1/4 keV band with data from the ROSAT All-Sky Survey toward the North Ecliptic Pole and SEP, when the He cone was probably first detected in soft X-rays.

  12. Transnationalism as a motif in family stories.

    2005-12-01

    Family stories have long been recognized as a vehicle for assessing components of a family's emotional and social life, including the degree to which an immigrant family has been willing to assimilate. Transnationalism, defined as living in one or more cultures and maintaining connections to both, is now increasingly common. A qualitative study of family stories in the family of those who appear completely "American" suggests that an affiliation with one's home country is nevertheless detectable in the stories via motifs such as (1) positively connotated home remedies, (2) continuing denigration of home country "enemies," (3) extensive knowledge of the home country history and politics, (4) praise of endogamy and negative assessment of exogamy, (5) superiority of home country to America, and (6) beauty of home country. Furthermore, an awareness of which model--assimilationist or transnational--governs a family's experience may help clarify a clinician's understanding of a family's strengths, vulnerabilities, and mode of framing their cultural experiences.

    Rhythmic neuronal oscillations across a broad range of frequencies, as well as spatiotemporal phenomena, such as waves and bumps, have been observed in various areas of the brain and proposed as critical to brain function. While there is a long and distinguished history of studying rhythms in nerve cells and neuronal networks in healthy organisms, the association and analysis of rhythms to diseases are more recent developments. Indeed, it is now thought that certain aspects of diseases of the nervous system, such as epilepsy, schizophrenia, Parkinson's, and sleep disorders, are associated with transitions or disruptions of neurological rhythms. This focus issue brings together articles presenting modeling, computational, analytical, and experimental perspectives about rhythms and dynamic transitions between them that are associated to various diseases.

    The shaping and formation of the current sheath takes place in the breakdown phase of a plasma focus device and critically controls the device performance. Electrostatic particle in cell codes, with magnetic effects ignored, have been used to model the breakdown phase. This Letter reports the successful development and implementation of an electromagnetic particle in cell (EMPIC) code, including magnetic effects self-consistently, to simulate the breakdown phase; from the ionization, localization and gliding discharge along the insulator to the time instant of current sheath lift off. The magnetic field was found to be appreciable from the time the current sheath came into contact with the anode with increased local current, initiating the voltage breakdown of the device as a result

    2016-11-01

    The enhanced heating effect during the combination of high-intensity focused ultrasound (HIFU) and low-optical-fluence laser illumination was investigated by using an in vivo murine animal model. The thighs of murine animals were synergistically irradiated by HIFU and pulsed nano-second laser light. The temperature increases in the target region were measured by a thermocouple under different HIFU pressures, which were 6.2, 7.9, and 9.8 MPa, in combination with 20 mJ/cm2 laser exposures at 532 nm wavelength. In comparison with conventional laser therapies, the laser fluence used here is at least one order of magnitude lower. The results showed that laser illumination could enhance temperature during HIFU applications. Additionally, cavitation activity was enhanced when laser and HIFU irradiation were concurrently used. Further, a theoretical simulation showed that the inertial cavitation threshold was indeed decreased when laser and HIFU irradiation were utilized concurrently.

    The ORNL superconducting motor, is a device consisting of 4 DC superconducting magnets in a square cross section. These coils are arranged in a N-S-N-S configuration and at present have no iron flux return paths. Experimentally the device has been operated and has been shown to produce 102.3 kg-m of locked rotor torque at 100 Ampers winding current. The superconductors were operating at 40 Kelvin. The peak magnetic field at 2,100 amperes operating current was 2 Tesla on the cryostat face. Recently there has been an effort under way to improve the operating parameters of the device by improving the flux utilization of the device. This was to be accomplished by the use of flux focusing pole pieces. The effects of the pole pieces and the vacuum magnetic field have been modeled with the MSC EMAS code to see the possible benefit of adding pole pieces to the in situ experiment

  19. "Who Are You From?": The Importance of Family Stories.

    2017-11-01

    This article emphasizes the importance of family stories, or intergenerational narratives, and their health benefits across the lifespan. Knowing and sharing the story of who you are from complements the current focus on knowing and sharing one's geographic heritage, or where you are from. Knowing one's family stories creates meaning that goes beyond the individual to provide a sense of self, through time, and in relation to family. This expanded sense of self is referred to as our intergenerational self, which not only grounds an individual but also provides a larger context for understanding and dealing with life's experience(s) and challenges. This connection across generations appears to contribute to resilience at all stages of life. This shift in focus challenges family nurses to rethink and/or prioritize the use of family stories as a key health-promoting intervention for not only children but also their parents, and their parents' parents.

    The simplified model is proposed to simulate numerically air breakdown in a focused microwave beam. The model is 1D from the mathematical point of view, but it takes into account the spatial non-uniformity of microwave field amplitude along the beam axis. The simulations are completed for different frequencies and different focal lengths of microwave beams. The results demonstrate complicated regimes of the breakdown evolution which represents a series of repeated ionization waves. These waves start at the focal point and propagate towards incident microwave radiation. The ionization wave parameters vary during propagation. At relatively low frequencies, the propagation regime of subsequent waves can also change qualitatively. Each next ionization wave is less pronounced than the previous one, and the breakdown evolution approaches the steady state with relatively small plasma density. The ionization wave parameters are sensitive to the weak source of external ionization, but the steady state is independent on such a source. As the beam focal length decreases, the stationary plasma density increases and the onset of the steady state occurs faster.

    Full Text Available Lo studio delle narrazioni di genere all'interno di questo tipo di organizzazione desta inoltre un particolare interesse anche in ragione della sottorappresentazione delle donne nella sfera della politica. Si tratta di un deficit democratico che coinvolge i sistemi politici moderni nel loro complesso, ma che interessa l'Italia con una particolare gravità ed evidenza. La questione della sottorappresentazione politica delle donne è stata sinora affrontata prevalentemente in termini tecnico-legali (politiche di pari opportunità ed azione positiva, o di teoria politica (la dicotomia pubblico-maschile e privato-femminile come fondamento del contratto sessuale della politica. Mancano invece contributi che guardino ai partiti come organizzazioni largamente responsabili dei processi di selezione e promozione delle carriere politiche, dunque come luoghi di quotidiana produzione di pratiche e culture di genere, più o meno egualitarie o, viceversa, discriminatorie. Sulla base di tale vuoto di ricerca e riflessione, il presente articolo si propone di mettere in luce le pratiche e le culture di genere che emergono dai racconti di uomini e donne all'interno di due organizzazioni partitiche, una di destra e una di sinistra, situate nel contesto territoriale della provincia di Trento. La ricerca è stata condotta attraverso lo strumento dell'intervista semi-strutturata, coinvolgendo quattro donne e quattro uomini, divisi per coppie di età (un uomo ed una donna giovani ed un uomo ed una donna da lungo presenti nel partito, accostabili per quanto concerne ruolo e posizione nelle organizzazioni partitiche considerate.

    While the US population overall has experienced improvements in oral health over the past 60 years, oral diseases remain among the most common chronic conditions across the life course. Further, lack of access to oral health care contributes to profound and enduring oral health inequities worldwide. Vulnerable and underserved populations who commonly lack access to oral health care include racial/ethnic minority older adults living in urban environments. The aim of this study was to use a systematic approach to explicate cause and effect relationships in creating a causal map, a type of concept map in which the links between nodes represent causality or influence. To improve our mental models of the real world and devise strategies to promote oral health equity, methods including system dynamics, agent-based modeling, geographic information science, and social network simulation have been leveraged by the research team. The practice of systems science modeling is situated amidst an ongoing modeling process of observing the real world, formulating mental models of how it works, setting decision rules to guide behavior, and from these heuristics, making decisions that in turn affect the state of the real world. Qualitative data were obtained from focus groups conducted with community-dwelling older adults who self-identify as African American, Dominican, or Puerto Rican to elicit their lived experiences in accessing oral health care in their northern Manhattan neighborhoods. The findings of this study support the multi-dimensional and multi-level perspective of access to oral health care and affirm a theorized discrepancy in fit between available dental providers and patients. The lack of information about oral health at the community level may be compromising the use and quality of oral health care among racial/ethnic minority older adults. Well-informed community members may fill critical roles in oral health promotion, as they are viewed as highly credible

    When you're in the midst of a major career change, telling stories about your professional self can inspire others' belief in your character and in your capacity to take a leap and land on your feet. It also can help you believe in yourself. A narrative thread will give meaning to your career history; it will assure you that, in moving on to something new, you are not discarding everything you've worked so hard to accomplish. Unfortunately, the authors explain in this article, most of us fail to use the power of storytelling in pursuit of our professional goals, or we do it badly. Tales of transition are especially challenging. Not knowing how to reconcile the built-in discontinuities in our work lives, we often relay just the facts. We present ourselves as safe--and dull and unremarkable. That's not a necessary compromise. A transition story has inherent dramatic appeal. The protagonist is you, of course, and what's at stake is your career. Perhaps you've come to an event or insight that represents a point of no return. It's this kind of break with the past that will force you to discover and reveal who you really are. Discontinuity and tension are part of the experience. If these elements are missing from your career story, the tale will fall flat. With all these twists and turns, how do you demonstrate stability and earn listeners' trust? By emphasizing continuity and causality--in other words, by showing that your past is related to the present and, from that trajectory, conveying that a solid future is in sight. If you can make your story of transition cohere, you will have gone far in convincing the listener--and reassuring yourself--that the change makes sense for you and is likely to bring success.

  4. Stories as case knowledge: case knowledge as stories.

    Every case contains a human story of illness and a medical story of disease, which together cover person management, case management, health system management and self-management. Much of that management can be learned via a thorough set of stories of typical and atypical core cases compiled by clinical teachers. Stories provide a highly flexible framework for illustrating the lessons of experience, the tips and traps for young players, and the dilemmas requiring careful judgement in the trade-offs between benefits and risks. Listening to real stories unfold is much more fun than being lectured (and better remembered). Stories illustrate 'what can happen' in a case as a guide to 'what to do'. A story begins with a real world situation with some predicament and a (causal) sequence of events or plot in which things are resolved one way or another. Patients tell their illness story; their clinician translates that into a disease story. Stories sort out what is important in such a predicament, consider the strategy and tactics of what to do, and speak about the outcomes. Each local situation provides relevance, context and circumstantial detail. Stories about case management can encapsulate practical knowledge, logical deduction, judgement and decision making, sharing with the student all the ingredients that develop expertise. Sometimes it is the plot that is important, sometimes the detail, sometimes it is the underlying message, the parable that resonates with the listener's experiences and feelings.1 Stories can also accommodate the complexity of multiple variables and the influence of other stakeholders, the uncertainties and dilemmas within the trade-offs, and the niceties of 'informed judgement'. This paper makes four points. First, clinical stories recount pointed examples of 'what happened' that expand our expertise in handling 'a case like that'. Second, cases are the unit of clinical work. Case stories expand the dimensions and details of case knowledge

    A theoretical model of focused acoustic field for a multi-annular phased array on concave spherical surface is proposed. In this model, the source boundary conditions of the spheroidal beam equation (SBE) for multi-annular phased elements are studied. Acoustic field calculated by the dynamic focusing model of SBE is compared with numerical results of the O'Neil and Khokhlov-Zabolotskaya-Kuznetsov (KZK) model, respectively. Axial dynamic focusing and the harmonic effects are presented. The results demonstrate that the dynamic focusing model of SBE is good valid for a concave multi-annular phased array with a large aperture angle in the linear or nonlinear field.

    Accurate lung nodule segmentation from computed tomography (CT) images is of great importance for image-driven lung cancer analysis. However, the heterogeneity of lung nodules and the presence of similar visual characteristics between nodules and their surroundings make it difficult for robust nodule segmentation. In this study, we propose a data-driven model, termed the Central Focused Convolutional Neural Networks (CF-CNN), to segment lung nodules from heterogeneous CT images. Our approach combines two key insights: 1) the proposed model captures a diverse set of nodule-sensitive features from both 3-D and 2-D CT images simultaneously; 2) when classifying an image voxel, the effects of its neighbor voxels can vary according to their spatial locations. We describe this phenomenon by proposing a novel central pooling layer retaining much information on voxel patch center, followed by a multi-scale patch learning strategy. Moreover, we design a weighted sampling to facilitate the model training, where training samples are selected according to their degree of segmentation difficulty. The proposed method has been extensively evaluated on the public LIDC dataset including 893 nodules and an independent dataset with 74 nodules from Guangdong General Hospital (GDGH). We showed that CF-CNN achieved superior segmentation performance with average dice scores of 82.15% and 80.02% for the two datasets respectively. Moreover, we compared our results with the inter-radiologists consistency on LIDC dataset, showing a difference in average dice score of only 1.98%. Copyright © 2017. Published by Elsevier B.V.

    A prolonged imbalance between a relative increase in energy intake over a decrease in energy expenditure results in the development of obesity; extended periods of a positive energy balance eventually lead to the accumulation of abnormally high amounts of fat in adipose tissue but also in other organs. Obesity is considered a clinical state of impaired general heath in which the excessive increase in adipose tissue mass may be associated with metabolic disorders such as type 2 diabetes mellitus, hyperlipidemia, hypertension and cardiovascular diseases. This review discusses briefly the use of animal models for the study of obesity and its comorbidities. Generally, most studies are performed with rodents, such as diet induced obesity and genetic models. Here, we focus specifically on two different species, namely dogs and cats. Obese dogs and cats show many features of human obesity. Interestingly, however, dogs and cats differ from each other in certain aspects because even though obese dogs may become insulin resistant, this does not result in the development of diabetes mellitus. In fact, diabetes in dogs is typically not associated with obesity because dogs present a type 1 diabetes-like syndrome. On the other hand, obese cats often develop diabetes mellitus which shares many features with human type 2 diabetes; feline and human diabetes are similar in respect to their pathophysiology, underlying risk factors and treatment strategies. Our review discusses genetic and endocrine factors in obesity, discusses obesity induced changes in lipid metabolism and includes some recent findings on the role of gut microbiota in obesity. Compared to research in rodent models, the array of available techniques and tools is unfortunately still rather limited in dogs and cats. Hence, even though physiological and pathophysiological phenomena are well described in dogs and cats, the underlying mechanisms are often not known and studies investigating causality specifically are

    This paper presents a new model of category judgment. The model hypothesizes that, when more attention is focused on a category, the psychological range of the category gets narrower (category-focusing hypothesis). We explain this hypothesis by using the metaphor of a "mental-box" model: the more attention that is focused on a mental box (i.e., a category set), the smaller the size of the box becomes (i.e., a cardinal number of the category set). The hypothesis was tested in an experiment (N = 40), where the focus of attention on prescribed verbal categories was manipulated. The obtained data gave support to the hypothesis: category-focusing effects were found in three experimental tasks (regarding the category of "food", "height", and "income"). The validity of the hypothesis was discussed based on the results.

    Background Although the precise pathophysiology of irritable bowel syndrome (IBS) remains unknown, it is generally considered to be a disorder of the brain-gut axis, representing the disruption of communication between the brain and the digestive system. The present review describes advances in understanding the pathophysiology and experimental approaches in studying IBS, as well as providing an update of the therapies targeting brain-gut axis in the treatment of the disease. Methods Causal factors of IBS are reviewed. Following this, the preclinical experimental models of IBS will be introduced. Besides, both current and future therapeutic approaches of IBS will be discussed. Results When signal of the brain-gut axis becomes misinterpreted, it may lead to dysregulation of both central and enteric nervous systems, altered intestinal motility, increased visceral sensitivity and consequently contributing to the development of IBS. Interference of the brain-gut axis can be modulated by various psychological and environmental factors. Although there is no existing animal experiment that can represent this complex multifactorial disease, these in vivo models are clinically relevant readouts of gastrointestinal functions being essential to the identification of effective treatments of IBS symptoms as well as their molecular targets. Understanding the brain-gut axis is essential in developing the effective therapy for IBS. Therapies include improvement of GI motor functions, relief of visceral hypersensitivity and pain, attenuation of autonomic dysfunctions and suppression of mucosal immune activation. Conclusion Target-oriented therapies that provide symptomatic, psychological and physiological benefits could surely help to improve the quality of life of IBS patients. PMID:27009115

  10. Modelling and simulation of flight control electromechanical actuators with special focus on model architecting, multidisciplinary effects and power flows

    2017-02-01

    Full Text Available In the aerospace field, electromechanical actuators are increasingly being implemented in place of conventional hydraulic actuators. For safety-critical embedded actuation applications like flight controls, the use of electromechanical actuators introduces specific issues related to thermal balance, reflected inertia, parasitic motion due to compliance and response to failure. Unfortunately, the physical effects governing the actuator behaviour are multidisciplinary, coupled and nonlinear. Although numerous multi-domain and system-level simulation packages are now available on the market, these effects are rarely addressed as a whole because of a lack of scientific approaches for model architecting, multi-purpose incremental modelling and judicious model implementation. In this publication, virtual prototyping of electromechanical actuators is addressed using the Bond-Graph formalism. New approaches are proposed to enable incremental modelling, thermal balance analysis, response to free-run or jamming faults, impact of compliance on parasitic motion, and influence of temperature. A special focus is placed on friction and compliance of the mechanical transmission with fault injection and temperature dependence. Aileron actuation is used to highlight the proposals for control design, energy consumption and thermal analysis, power network pollution analysis and fault response.

  11. Model study of multiphase DMS oxidation with a focus on halogens

    2004-01-01

    Full Text Available We studied the oxidation of dimethylsulfide (DMS in the marine boundary layer (MBL with a one-dimensional numerical model and focused on the influence of halogens. Our model runs show that there is still significant uncertainty about the end products of the DMS addition pathway, which is especially caused by uncertainty in the product yield of the reaction of the intermediate product methyl sulfinic acid (MSIA with OH. BrO strongly increases the importance of the addition branch in the oxidation of DMS even when present at mixing ratios smaller than 0.5pmol mol-1. The inclusion of halogen chemistry leads to higher DMS oxidation rates and smaller DMS to SO2 conversion efficiencies. The DMS to SO2 conversion efficiency is also drastically reduced under cloudy conditions. In cloud-free model runs between 5 and 15% of the oxidized DMS reacts further to particulate sulfur, in cloudy runs this fraction is almost 100%. Sulfate production by HOClaq and HOBraq is important in cloud droplets even for small Br- deficits and related small gas phase halogen concentrations. In general, more particulate sulfur is formed when halogen chemistry is included. A possible enrichment of HCO3- in fresh sea salt aerosol would increase pH values enough to make the reaction of S(IV* (=SO2,aq+HSO3-+SO32- with O3 dominant for sulfate production. It leads to a shift from methyl sulfonic acid (MSA to non-sea salt sulfate (nss-SO42- production but increases the total nss-SO42- only somewhat because almost all available sulfur is already oxidized to particulate sulfur in the base scenario. We discuss how realistic this is for the MBL. We found the reaction MSAaq+OH to contribute about 10% to the production of nss-SO42- in clouds. It is unimportant for cloud-free model runs. Overall we find that the presence of halogens leads to processes that decrease the albedo of stratiform clouds in the MBL.

  13. Resilience assessment of interdependent infrastructure systems: With a focus on joint restoration modeling and analysis

    International Nuclear Information System (INIS)

    Ouyang, Min; Wang, Zhenghua

    2015-01-01

    As infrastructure systems are highly interconnected, it is crucial to analyze their resilience with the consideration of their interdependencies. This paper adapts an existing resilience assessment framework for single systems to interdependent systems and mainly focuses on modeling and resilience contribution analysis of multi-systems’ joint restoration processes, which are seldom addressed in the literature. Taking interdependent power and gas systems in Houston, Texas, USA under hurricane hazards as an illustrative exmaple, five types of joint restoration stategies are proposed, including random restoration strategy RS 1 , independent restoration strategy RS 2 , power first and gas second restoration strategy RS 3 , gas aimed restoration strategy RS 4 , and power and gas compromised restoration strategy RS 5 . Results show that under limited restoration resources, RS 1 produces the least resilience for both systems, RS 2 and RS 3 both generates the largest power system resilience while RS 4 is the best for the gas system; and if quantifying the total resilience as the evenly weighted sum of two systems’ individual resilience, RS 5 produces the largest total resilience. The proposed method can help decision makers search optimum joint restoration strategy, which can significantly enhance both systems’ resilience. - Highlights: • We propose a method to assess resilience of interdependent infrastructure systems. • We consider unidirectional interdependencies from power system to gas system. • Multi-systems’ restoration processes are solved by using genetic algorithm. • Effectiveness of five restoration strategies are compared and analyzed. • Interdependency-based strategies produce the largest total resilience

    Mechatronics is a model of transdisciplinary integration, entirely functional, with remarkable results for mankind. The incredible progress that the global economy has taken in the last decades is based on this new approach, the integrative type, which is present at the foundation of mechatronics. This kind of integrative approach is necessary for building a quality education focused on competence. The requirements from the social and economic environment, the needs of the young people who prepare themselves for an active life and the offers of the education providers are still not too interconnected to offer a satisfying education. This is the reason why the efforts to balance the demand, the needs and the offer are essential to ensure a better integration of students into society. Using a transcultural perspective, we can achieve a constructive approach. The education providers, together with the socio-economic environment, establish a clear structure of competence in multiple domains and of the instruments which can assure it. The scientific demarche, in the spirit of this paper approach the, answers the natural questions from the educational process: „Why, How and What do I learn?”.

    New discoveries in basic science are creating extraordinary opportunities to design novel biomedical preventions and therapeutics for human disease. But the clinical evaluation of these new interventions is, in many instances, being hindered by a variety of legal, regulatory, policy and operational factors, few of which enhance research quality, the safety of study participants or research ethics. With the goal of helping increase the efficiency and effectiveness of clinical research, we have examined how the integration of utilization-focused evaluation with elements of business process modeling can reveal opportunities for systematic improvements in clinical research. Using data from the NIH global HIV/AIDS clinical trials networks, we analyzed the absolute and relative times required to traverse defined phases associated with specific activities within the clinical protocol lifecycle. Using simple median duration and Kaplan-Meyer survival analysis, we show how such time-based analyses can provide a rationale for the prioritization of research process analysis and re-engineering, as well as a means for statistically assessing the impact of policy modifications, resource utilization, re-engineered processes and best practices. Successfully applied, this approach can help researchers be more efficient in capitalizing on new science to speed the development of improved interventions for human disease.

  16. Stories, Heroes and Commercials. Spreading the Message across with a New Type of Responsibility

    Full Text Available Stories have always been a form of communication, the first form of narrative we have encountered in early childhood. And although we have grown up they continue to fascinate us. They maintain and recreate bonds with old traditions, legends, archetypes, myths and symbols. In analyzing stories, Joseph Campbell (2008 proposed the monomyth or the Hero's Journey, a basic pattern, which comprises fundamental stages and structures identifiable in all narratives from different cultures and ages. Although the pattern was further refined and enriched according to the specifics of the narrative (myth, fairy tale, dream, movie etc. the common structural elements of the Hero's Journey from the ordinary world to a challenging and unfamiliar world include: the departure, the initiation and the return. Picking up on Campbell’s model, Sachs (2012 proposes a circular representation of the hero and his/her journey. In this model, a new character, the mentor, plays a pivotal role in the shaping of the hero and his/her transformation. It is the mentor that supports the hero in her/his taking the call to adventure as well as in providing the needed support for crossing the thresholds to the supernatural world and back. Based on what Sachs (2012 suggests that brands could use storytelling as a means to engage with consumers. In doing so he argues that brands should reflect and adopt the role of mentors in their consumers’ journeys, guiding them through the challenges on their own world and contributing to their personal fulfillment. This paper aims to evaluate four stories, all focused on women and empowerment and as a result our discussion focuses mainly on the position of the brand within the story and its role. This, we believe, may contribute to a new trend focused on the adoption and applications of empowerment storytelling.

These stories replicate and describe the environment in which the Gypsy ancestors struggled to survive. As a consequence, the narratives and the Gypsy real world are compatible in many constant and predictable ways, and many Gypsies are hence able to use narrative information/knowledge as a model for proper behavior which helps them to negotiate their social environment in their efforts to survive and reproduce.

  18. Modeling and experimental investigations of Lamb waves focusing in anisotropic plates

    International Nuclear Information System (INIS)

    Chapuis, Bastien; Terrien, Nicolas; Royer, Daniel

    2011-01-01

    The phenomenon of Lamb waves focusing in anisotropic plates is theoretically and experimentally investigated. An analysis based on a far field approximation of the Green's function shows that Lamb waves focusing is analog to the phonon focusing effect. In highly anisotropic structures like composite plates the focusing of A 0 and S 0 mode is strong; the energy propagates preferentially in the fibre directions, which are minima of the slowness. This has to be taken into account when developing, for example, a transducer array for structural health monitoring systems based on Lamb waves in order to avoid dead zones.

    Computer animations are a powerful tool for explanation and communication of ideas, especially to a younger generation. Our team completed a three part sequence of short, computer animated stories about the insight and discoveries that lead to the understanding of the overall structure of the universe. Our principal characters are Immanuel Kant, Henrietta Leavitt, and Edwin Hubble. We utilized animations to model and visualize the physical concepts behind each discovery and to recreate the characters, locations, and flavor of the time. The animations vary in length from 6 to 11 minutes. The instructors or presenters may wish to utilize them separately or together. The animations may be used for learning classical cosmology in a visual way in GE astronomy courses, in pre-college science classes, or in public science education setting.

    Full Text Available Once released into the air, humidifier disinfectants became tiny nano-size particles, and resulted in chemical bronchoalveolitis. Families had lost their most beloved members, and even some of them became broken. Based on an estimate of two million potential victims who had experienced adverse effects from the use of humidifier disinfectants, we can say that what we have observed was only the tip of the iceberg. Problems of entire airways, as well as other systemic effects, should be examined, as we know these nano-size particles can irritate cell membranes and migrate into systemic circulation. The story of humidifier disinfectant is not finished yet.

    Laing, Catherine M; Moules, Nancy J; Estefan, Andrew; Lang, Mike

    The purpose of this philosophical hermeneutic study was to understand the effects on health care providers (HCPs) of watching digital stories made by (past and present) pediatric and adolescent/young adult (AYA) oncology patients. Twelve HCPs participated in a focus group where they watched digital stories made by pediatric/AYA oncology patients and participated in a discussion related to the impact the stories had on them personally and professionally. Findings from this research revealed that HCPs found digital stories to be powerful, therapeutic, and educational tools. Health care providers described uses for digital stories ranging from education of newly diagnosed families to training of new staff. Digital stories, we conclude, can be an efficient and effective way through which to understand the patient experience, implications from which can range from more efficient patient care delivery to decision making. Recommendations for incorporating digital storytelling into healthcare delivery are offered.

    Full Text Available One of marketers’ chief objectives is to achieve customer loyalty, which is a key factor for profitable growth. Therefore, they need to develop a strategy that attracts and maintains customers, giving them adequate motives, both tangible (prices and promotions and intangible (personalized service and treatment, to satisfy a customer and make him loyal to the company. Finding a way to accurately measure satisfaction and customer loyalty is very important. With regard to typical Relationship Marketing measures, we can consider listening to customers, which can help to achieve a competitive sustainable advantage. Customer satisfaction surveys are essential tools for listening to customers. Short questionnaires have gained considerable acceptance among marketers as a means to achieve a customer satisfaction measure. Our research provides an indication of the benefits of a short questionnaire (one/three questions. We find that the number of questions survey is significantly related to the participation in the survey (Net Promoter Score or NPS. We also prove that a the three question survey is more likely to have more participants than a traditional survey (Maximum Potential Score or MPS . Our main goal is to analyse one method as a potential predictor of customer loyalty. Using surveys, we attempt to empirically establish the causal factors in determining the satisfaction of customers. This paper describes a maximum potential operating model that captures with a three questions survey, important elements for a successful customer-focused strategy. MPS may give us lower participation rates than NPS but important information that helps to convert unhappy customers or just satisfied customers, into loyal customers.

    People often report positive psychological changes after adversity, a phenomenon known as posttraumatic growth (PTG). Few PTG-focused interventions have been rigorously tested, and measurement strategies have had significant limitations. This study evaluated the effects of a new group-format psychosocial intervention, SecondStory, aimed at facilitating PTG by helping participants make meaning of the past and plan a purposeful future. In a randomized controlled trial, adults (N = 112, 64% women) bereaved within 5 years were randomly assigned to SecondStory or an active control, expressive writing. The primary outcome, PTG, was measured using two contrasting methods: the Posttraumatic Growth Inventory, which asks participants retrospectively how much they believe they have changed due to struggling with adversity, and the Current-Standing Posttraumatic Growth Inventory, which tracks quantifiable change in participants' standing in PTG domains over time. Secondary outcomes included depression symptoms, posttraumatic stress symptoms, and life satisfaction. Outcomes were measured at 2-week intervals: pretest, posttest, and three follow-up occasions. Hierarchical linear modeling was used to assess whether SecondStory participants experienced greater gains in primary and/or secondary outcomes over the 8-week trial. Results indicated that SecondStory participants did not show significantly greater improvements than control participants on measures of PTG, posttraumatic stress, or life satisfaction, but they did show greater decreases in depression symptoms by the first follow-up. These findings suggest that SecondStory may not facilitate PTG more effectively than existing interventions but may be promising for addressing depression. Positive interventions may productively be refined to support people experiencing trauma and loss. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

  18. Foundational Tests of the Need-Support Model: A Framework for Bridging Regulatory Focus Theory and Self-Determination Theory.

    Science.gov (United States)

    Vaughn, Leigh Ann

    2017-03-01

    This article introduces the need-support model, which proposes that regulatory focus can affect subjective support for the needs proposed by self-determination theory (autonomy, competence, and relatedness), and support of these needs can affect subjective labeling of experiences as promotion-focused and prevention-focused. Three studies tested these hypotheses ( N = 2,114). Study 1 found that people recall more need support in promotion-focused experiences than in prevention-focused experiences, and need support in their day yesterday (with no particular regulatory focus) fell in between. Study 2 found that experiences of higher need support were more likely to be labeled as promotion-focused rather than prevention-focused, and that each need accounted for distinct variance in the labeling of experiences. Study 3 varied regulatory focus within a performance task and found that participants in the promotion condition engaged in need-support inflation, whereas participants in the prevention condition engaged in need-support deflation. Directions for future research are discussed.

Adopting Nussbaum's (2010 capabilities framework for a socially just democracy, this paper examines 27 pre-service teacher education students' perceptions of a digital storytelling project and its potential for recognising and honouring capabilities necessary for engaging empathetically with the 'other'. Using narrative inquiry, and specifically Bamberg's (2006 'small stories' approach, the research team analysed 30 stories students constructed in four focus group conversations at the end of the project. In these stories, most of Nussbaum's (2010 capabilities were evident. We found that, in the collective sharing of their stories, students positioned themselves as agentive selves, displaying the belief that they can make a difference, not only individually within their own classrooms, but also as a collective of teachers.

  20. Story-telling, women's authority and the "Old Wife's Tale": "The Story of the Bottle of Medicine".

    Science.gov (United States)

    Abrams, Lynn

    2012-01-01

    The focus of this article is a single personal narrative – a Shetland woman's telling of a story about two girls on a journey to fetch a cure for a sick relative from a wise woman. The story is treated as a cultural document which offers the historian a conduit to a past that is respectful of indigenous woman-centred interpretations of how that past was experienced and understood. The "story of the bottle of medicine" is more than a skilful telling of a local tale; it is a memory practice that provides a path to a deeper and more nuanced understanding of a culture. Applying perspectives from anthropology, oral history and narrative analysis, three sets of questions are addressed: the issue of authenticity; the significance of the narrative structure and storytelling strategies employed; and the nature of the female performance. Ultimately the article asks what this story can tell us about women's interpretation of their own history.

    Lobster-eye optics is widely applied to space x-ray detection missions and x-ray security checks for its wide field of view and low weight. This paper presents a theoretical model to obtain spatial distribution of focusing efficiency based on lobster-eye optics in a soft x-ray wavelength. The calculations reveal the competition mechanism of contributions to the focusing efficiency between the geometrical parameters of lobster-eye optics and the reflectivity of the iridium film. In addition, the focusing efficiency image depending on x-ray wavelengths further explains the influence of different geometrical parameters of lobster-eye optics and different soft x-ray wavelengths on focusing efficiency. These results could be beneficial to optimize parameters of lobster-eye optics in order to realize maximum focusing efficiency.

  7. On various metrics used for validation of predictive QSAR models with applications in virtual screening and focused library design.

    Quantitative structure-activity relationships (QSARs) have important applications in drug discovery research, environmental fate modeling, property prediction, etc. Validation has been recognized as a very important step for QSAR model development. As one of the important objectives of QSAR modeling is to predict activity/property/toxicity of new chemicals falling within the domain of applicability of the developed models and QSARs are being used for regulatory decisions, checking reliability of the models and confidence of their predictions is a very important aspect, which can be judged during the validation process. One prime application of a statistically significant QSAR model is virtual screening for molecules with improved potency based on the pharmacophoric features and the descriptors appearing in the QSAR model. Validated QSAR models may also be utilized for design of focused libraries which may be subsequently screened for the selection of hits. The present review focuses on various metrics used for validation of predictive QSAR models together with an overview of the application of QSAR models in the fields of virtual screening and focused library design for diverse series of compounds with citation of some recent examples.

    While previous studies have considered medical student burnout and resilience at discrete points in students' training, few studies examine how stressors and resilience-building factors can emerge before, and during, medical school. Our study focuses on students' life stories to comprehensively identify factors contributing to student wellbeing. We performed a secondary analysis of life-story interviews with graduating fourth year medical students. These interviews were originally conducted in 2012 as part of the Project on the Good Physician, and then re-analyzed, focusing on student wellbeing. Respondents were encouraged to identify turning points in their life stories. De-identified transcripts were then coded using a consensus-based iterative process. 17 of 21 respondents reported feeling burned out at least once during medical school. Students identified three major stressors: negative role models, difficult rotations, and the United States Medical Licensing Examination Step 1. Two "motivational stressors"-financial concerns and personal life events-emerged as sources of stress that also motivated students to persevere. Finally, students identified four factors-positive role models, support networks, faith and spirituality, and passion-that helped them reframe stressors, making the struggle seem more worthwhile. These findings suggest that a life-story approach can add granularity to current understandings of medical student wellbeing. Initiatives to reduce stress and burnout should extend beyond the immediate medical school context and consider how past challenges might become future sources of resilience. This study also provides an example of secondary analysis of qualitative data, an approach which could be useful to future research in medical education.

    Full Text Available This paper links professional service firms’ resource-based strategies to their customer-focused performance for formulating service quality improvement priorities. The research applies the structural equation modelling approach to survey data from Hong Kong construction consultants to test some hypotheses. The study validates the various measures of firms’ resource-based strategies and customer-focused performance and bridges the gaps in firms’ organizational learning, core competences and customer-focused performance mediated by their strategic flexibility. The research results have practical implications for professional service firms to deploy resources appropriately to first enhance different competences and then improve customerfocused performance using their different competences.

  10. Envelope model for passive magnetic focusing of an intense proton or ion beam propagating through thin foils

    Directory of Open Access Journals (Sweden)

    Steven M. Lund

    2013-04-01

    Full Text Available Ion beams (including protons with low emittance and high space-charge intensity can be propagated with normal incidence through a sequence of thin metallic foils separated by vacuum gaps of order the characteristic transverse beam extent to transport/collimate the beam or to focus it to a small transverse spot. Energetic ions have sufficient range to pass through a significant number of thin foils with little energy loss or scattering. The foils reduce the (defocusing radial electric self-field of the beam while not altering the (focusing azimuthal magnetic self-field of the beam, thereby allowing passive self-beam focusing if the magnetic field is sufficiently strong relative to the residual electric field. Here we present an envelope model developed to predict the strength of this passive (beam generated focusing effect under a number of simplifying assumptions including relatively long pulse duration. The envelope model provides a simple criterion for the necessary foil spacing for net focusing and clearly illustrates system focusing properties for either beam collimation (such as injecting a laser-produced proton beam into an accelerator or for magnetic pinch focusing to a small transverse spot (for beam driven heating of materials. An illustrative example is worked for an idealization of a recently performed laser-produced proton-beam experiment to provide guidance on possible beam focusing and collimation systems. It is found that foils spaced on the order of the characteristic transverse beam size desired can be employed and that envelope divergence of the initial beam entering the foil lens must be suppressed to limit the total number of foils required to practical values for pinch focusing. Relatively modest proton-beam current at 10 MeV kinetic energy can clearly demonstrate strong magnetic pinch focusing achieving a transverse rms extent similar to the foil spacing (20–50  μm gaps in beam propagation distances of tens of mm

    2012-01-01

    Full Text Available Background: Physicians have difficulty to subjectively estimate the cardiovascular risk of their patients. Using an estimate of global cardiovascular risk could be more relevant to guide decisions than using binary representation (presence or absence of risk factors data. The main aim of the paper is to compare different models of predicting the progress of a coronary artery diseases (CAD to help the decision making of physician. Methods: There are different standard models for predicting risk factors such as models based on logistic regression model, Cox regression model, dynamic logistic regression model, and simulation models such as Markov model and microsimulation model. Each model has its own application which can or cannot use by physicians to make a decision on treatment of each patient. Results: There are five main common models for predicting of outcomes, including models based on logistic regression model (for short-term outcomes, Cox regression model (for intermediate-term outcomes, dynamic logistic regression model, and simulation models such as Markov and microsimulation models (for long-term outcomes. The advantages and disadvantages of these models have been discussed and summarized. Conclusion: Given the complex medical decisions that physicians face in everyday practice, the multiple interrelated factors that play a role in choosing the optimal treatment, and the continuously accumulating new evidence on determinants of outcome and treatment options for CAD, physicians may potentially benefit from a clinical decision support system that accounts for all these considerations. The microsimulation model could provide cardiologists, researchers, and medical students a user-friendly software, which can be used as an intelligent interventional simulator.

    2013-06-01

    Full Text Available Why should we be concerned about the fate of literature as we move from a book culture to a screen culture in the digital age? Not primarily because we are losing our sense of story, but because we are losing our sense of the central importance of linguistic narrative. There is a difference. The technologies creating the digital revolution seem to devalue language and increasingly to do away with boundaries, celebrating instead speed and boundless exhilaration. The visual trumps the linguistic, the image and the screen trump the word and the book. As a result, we no longer seem to engage deeply with others or ourselves. We are beginning to move, in other words, from “a reading brain” to “a digital brain,” from a brain capable of deep reading and deep thinking to a brain increasingly addled by spectacle and surface sensation. We are losing our standing as “linguistic beings.”

    This paper is about better engineering of cyber-physical systems (CPSs) through better models. Deterministic models have historically proven extremely useful and arguably form the kingpin of the industrial revolution and the digital and information technology revolutions. Key deterministic models that have proven successful include differential equations, synchronous digital logic and single-threaded imperative programs. Cyber-physical systems, however, combine these models in such a way that determinism is not preserved. Two projects show that deterministic CPS models with faithful physical realizations are possible and practical. The first project is PRET, which shows that the timing precision of synchronous digital logic can be practically made available at the software level of abstraction. The second project is Ptides (programming temporally-integrated distributed embedded systems), which shows that deterministic models for distributed cyber-physical systems have practical faithful realizations. These projects are existence proofs that deterministic CPS models are possible and practical. PMID:25730486

    2018-03-01

    Full Text Available Storytelling is recognized as a valid and important method of communicating information and knowledge gleaned from volumes of ever-accumulating data. Practices of data-driven storytelling in journalism and geovisual analytics have contributed to the development of geovisual stories; also called story maps. The benefits of student-focused multi-thematic atlases and digital storytelling methods in education can also be realized in story maps. An online, interactive version of the original paper version of the Wyoming Student Atlas was developed using story mapping technology. Studies on best practices for data-driven storytelling and web map interaction were used to inform the transition of the atlas from a traditional paper format to a collection of story maps. Evaluation of the atlas story maps for educational purposes was conducted by observing students from multiple classrooms as they used the story maps in a lesson. The students and educators responded to a survey after using the story maps. Results of the survey show positive responses to the atlas story maps, including ease of use and preference over a traditional paper atlas. However, certain types of interaction with the map resulted in increased negative or uncertain responses from students concerning their perception of the atlas story maps.

    Research on autism has been gaining more and more attention. However, its aetiology is not entirely known and several factors are thought to contribute to the development of this neurodevelopmental disorder. These potential contributing factors range from genetic heritability to environmental effects. A significant number of reviews have already been published on different aspects of autism research as well as focusing on using animal models to help expand current knowledge around its aetiology. However, the diverse range of symptoms and possible causes of autism have resulted in as equally wide variety of animal models of autism. In this update article we focus only on the animal models with neurobehavioural characteristics of social deficit related to autism and present an overview of the animal models with alterations in brain regions, neurotransmitters, or hormones that are involved in a decrease in sociability.

    1995-01-01

    The relationship among the fragility of element, that of story and that of system, is examined using the Monte Carlo simulation. In this study, 2-story models whose stories consist of 2 ductile elements are employed. A method is proposed which includes a nonlinear effect into the evaluation of elements capacities. This method does not require the nonlinear MCS, therefore saving computational efforts. Also, a method to estimate the stories and the system fragilities is proposed.

    Sports are spontaneous generators of stories. Through skill and chance, the script of each game is dynamically written in real time by players acting out possible trajectories allowed by a sport's rules. By properly characterizing a given sport's ecology of "game stories," we are able to capture the sport's capacity for unfolding interesting narratives, in part by contrasting them with random walks. Here we explore the game story space afforded by a data set of 1310 Australian Football League (AFL) score lines. We find that AFL games exhibit a continuous spectrum of stories rather than distinct clusters. We show how coarse graining reveals identifiable motifs ranging from last-minute comeback wins to one-sided blowouts. Through an extensive comparison with biased random walks, we show that real AFL games deliver a broader array of motifs than null models, and we provide consequent insights into the narrative appeal of real games.

    2015-05-01

    A biopsychosocial approach and behaviour change strategies have long been proposed to serve as a basis for addressing current multifaceted health problems. This emphasis has implications for clinical reasoning of health professionals. This study's aim was to develop and validate a conceptual model to guide physiotherapists' clinical reasoning focused on clients' behaviour change. Phase 1 consisted of the exploration of existing research and the research team's experiences and knowledge. Phases 2a and 2b consisted of validation and refinement of the model based on input from physiotherapy students in two focus groups (n = 5 per group) and from experts in behavioural medicine (n = 9). Phase 1 generated theoretical and evidence bases for the first version of a model. Phases 2a and 2b established the validity and value of the model. The final model described clinical reasoning focused on clients' behaviour change as a cognitive, reflective, collaborative and iterative process with multiple interrelated levels that included input from the client and physiotherapist, a functional behavioural analysis of the activity-related target behaviour and the selection of strategies for behaviour change. This unique model, theory- and evidence-informed, has been developed to help physiotherapists to apply clinical reasoning systematically in the process of behaviour change with their clients.

    Full Text Available At Ordnance Survey, GB, we have taken an incremental approach to creating our 3D geospatial database. Research at Ordnance Survey has focused not only on methods for deriving 3D data, but also on the needs of the user in terms of the actual tasks they perform. This provides insights into the type and quality of the data required and how its quality is conveyed. In 2007, using task analysis and user-centred design, we derived a set of geometric characteristics of building exteriors that are relevant to one or more use contexts. This work has been valuable for guiding which building data to collect and how to augment our products. In 2014, we began to supply building height attributes as an alpha-release enhancement to our 2D topography data, OS MasterMap® Topography Layer. This is the first in a series of enhancements of our 2D data that forms part of a road map that will ultimately lead to a full range of 3D products. This paper outlines our research journey from the understanding of the key 3D building characteristics to the development of geo-spatial products and the specification of research. There remains a rich seam of research into methods for capturing user-focused, geo-spatial data to enable visualisation and analysis in three dimensions. Because the process of informing and designing a product is necessarily focused on the practicalities of production, storage and distribution, this paper is presented as a case report, as we believe our journey will be of interest to others involved in the capture of 3D buildings at a national level.

    2016-02-01

    Two models for the generation of self-oscillations of reed conical woodwinds are presented. The models use the fewest parameters (of either the resonator or the exciter), whose influence can be quickly explored. The formulation extends iterated maps obtained for lossless cylindrical pipes without reed dynamics. It uses spherical wave variables in idealized resonators, with one parameter more than for cylinders: the missing length of the cone. The mouthpiece volume equals that of the missing part of the cone, and is implemented as either a cylindrical pipe (first model) or a lumped element (second model). Only the first model adds a length parameter for the mouthpiece and leads to the solving of an implicit equation. For the second model, any shape of nonlinear characteristic can be directly considered. The complex characteristic impedance for spherical waves requires sampling times smaller than a round trip in the resonator. The convergence of the two models is shown when the length of the cylindrical mouthpiece tends to zero. The waveform is in semi-quantitative agreement with experiment. It is concluded that the oscillations of the positive episode of the mouthpiece pressure are related to the length of the missing part, not to the reed dynamics.

    Full Text Available Video game development is currently a very labour-intensive endeavour. Furthermore it involves multi-disciplinary teams of artistic content creators and programmers, whose typical working patterns are not easily meshed. SAGA is our first effort at augmenting the productivity of such teams. Already convinced of the benefits of DSLs, we set out to analyze the domains present in games in order to find out which would be most amenable to the DSL approach. Based on previous work, we thus sought those sub-parts that already had a partially established vocabulary and at the same time could be well modeled using classical computer science structures. We settled on the 'story' aspect of video games as the best candidate domain, which can be modeled using state transition systems. As we are working with a specific company as the ultimate customer for this work, an additional requirement was that our DSL should produce code that can be used within a pre-existing framework. We developed a full system (SAGA comprised of a parser for a human-friendly language for 'story events', an internal representation of design patterns for implementing object-oriented state-transitions systems, an instantiator for these patterns for a specific 'story', and three renderers (for C++, C# and Java for the instantiated abstract code.

    2017-09-01

    For performance optimization of Refrigerated Warehouses, design parameters are selected based on the physical parameters such as number of equipment and aisles, speeds of forklift for ease of modification. This paper provides a comprehensive framework approach for the system design of Refrigerated Warehouses. We propose a modeling approach which aims at the simulation optimization so as to meet required design specifications using the Design of Experiment (DOE) and analyze a simulation model using integrated aspect-oriented modeling approach (i-AOMA). As a result, this suggested method can evaluate the performance of a variety of Refrigerated Warehouses operations.

  9. Automated Reasoning Across Tactical Stories to Derive Lessons Learned

    J. Wesley Regian

    2008-06-01

    Full Text Available The Military Analogical Reasoning System (MARS is a performance support system and decision aid for commanders in Tactical Operations Centers. MARS enhances and supports the innate human ability for using stories to reason about tactical goals, plans, situations, and outcomes. The system operates by comparing many instances of stored tactical stories, determining which have analogous situations and lessons learned, and then returning a description of the lessons learned. The description of the lessons learned is at a level of abstraction that can be generalized to an appropriate range of tactical situations. The machine-understandable story representation is based on a military operations data model and associated tactical situation ontology. Thus each story can be thought of, and reasoned about, as an instance of an unfolding tactical situation. The analogical reasoning algorithm is based on Gentner's Structure Mapping Theory. Consider the following two stories. In the first, a U.S. platoon in Viet Nam diverts around a minefield and subsequently comes under ambush from a large hill overlooking their new position. In the second, a U.S. task force in Iraq diverts around a biochemical hazard and subsequently comes under ambush from the roof of an abandoned building. MARS recognizes these stories as analogical, and derives the following abstraction: When enemy-placed obstacles force us into an unplanned route, beware of ambush from elevation or concealment. In this paper we describe the MARS interface, military operations data model, tactical situation ontology, and analogical reasoning algorithm.

  10. Detective Stories from Sherlock Holmes to Whitechapel

    Full Text Available Detective Stories from Sherlock Holmes to Whitechapel Abstract The Victorian period in England was one of the most influential and important epochs in history. During Queen Victoria’s reign, England was arguably the most powerful nation in the world, setting standards for social, economic and industrial development. Among the rules of Victorian society were stringent codes pertaining to what was acceptable for men and women. Men were expected to hold decent jobs, marry respectable women, and create the next generation of proper British citizens. Women were raised to marry, breed virtuous English children, and live quietly in the confines of the household. As Elaine Showalter (1987 says Victorian households had different spheres for men and women. There were certain behavioral norms for men and women that were standard practice for asserting one’s proper gender codes. In his 1995 book Victorian Masculinities, Herbert Sussman identifies, within Victorian men’s writing, a method of constructing masculinity that opposes the dominant English model of manliness based on bourgeois domestic matrimony. During the first half of the Victorian period, normative masculinity required a man to master his psychic energy by establishing a bourgeois domestic identity founded on matrimony. However, this concept translates into the bachelordom plot, wherein male desire finds an appropriate outlet in a sidekick rather than a wife, thus, under the terms of popular middle-class belief, permanently affirming masculinity. When we come to 2010s a bestseller Whitechapel hinges on the same lone detective trying to pursue the killers and criminals. The purpose of this paper is to probe and grapple with the similarities and dissimilarities the detective genre from Sherlock Holmes to Whitechapel by focusing on the detective himself, the crime types, criminals- their motives and ethnic origins-, masculinity, and male-male bonding.

  11. NIB Commentary on Oncofertility Stories.

    Gremmels, Becket

    2017-01-01

    The authors of these stories describe tales of struggle with cancer and secondary infertility. Yet, they each have a different response to similar circumstances. Their stories touch on a lack of informed consent regarding infertility, spiritual discussions of the problem of evil, the need for improved collaboration among physicians to further care of the whole person, societal norms regarding reproduction and gender roles, the injustice of cancer in young people, and other topics. Of note, no stories mention prominent ethical concerns of in-vitro fertilization like how couples should deal with "extra" frozen embryos or concerns about the potential for commodification of children. This shows a disconnect between the concerns of bioethicists and the concerns of real patients facing actual problems. Both cancer patients and providers can learn something from these stories that directly apply to their lives.

  12. Transmedia storytelling on travel stories

    Full Text Available Travel stories form part of a great tradition inside Western Culture which has served historically to describe, to understand and to imagine other cul - tures and communities, far or near, being constituted into a real narra - tive genre. This type of story has been and is a reflection of the perception of the world based on the imaginary worlds created by the travelling narrators. How do modern authors of travel stories take advantage of the opportunities offered by transmedia storytelling? The present article explores the potential of these types of stories as a privileged object of study for transmedia storytelling studies, from the analysis of a sample of 80 narrative productions based on experiences of travel and presented in diverse editions of the Festival Le Grand Bivouac (France. It also shows the existence of a new contemporary trend inside this narrative form that transcends its literary nature.

    Comics have been used as a programming tool for agents, giving them instructions on how to act. In this thesis I do this in reverse, I use comics to describe the actions of agents already interacting with each other to create a storytelling engine that dynamically generate stories, based on the interaction of said agents. The model for the agent behaviours is based on the improvisational puppets model of Barbara Hayes-Roth. This model is chosen due to the nature of comics themselves. Comics ...

  14. Three-dimensional gravity modeling and focusing inversion using rectangular meshes.

    Energy Technology Data Exchange (ETDEWEB)

    Commer, M.

    2011-03-01

    Rectangular grid cells are commonly used for the geophysical modeling of gravity anomalies, owing to their flexibility in constructing complex models. The straightforward handling of cubic cells in gravity inversion algorithms allows for a flexible imposition of model regularization constraints, which are generally essential in the inversion of static potential field data. The first part of this paper provides a review of commonly used expressions for calculating the gravity of a right polygonal prism, both for gravity and gradiometry, where the formulas of Plouff and Forsberg are adapted. The formulas can be cast into general forms practical for implementation. In the second part, a weighting scheme for resolution enhancement at depth is presented. Modelling the earth using highly digitized meshes, depth weighting schemes are typically applied to the model objective functional, subject to minimizing the data misfit. The scheme proposed here involves a non-linear conjugate gradient inversion scheme with a weighting function applied to the non-linear conjugate gradient scheme's gradient vector of the objective functional. The low depth resolution due to the quick decay of the gravity kernel functions is counteracted by suppressing the search directions in the parameter space that would lead to near-surface concentrations of gravity anomalies. Further, a density parameter transformation function enabling the imposition of lower and upper bounding constraints is employed. Using synthetic data from models of varying complexity and a field data set, it is demonstrated that, given an adequate depth weighting function, the gravity inversion in the transform space can recover geologically meaningful models requiring a minimum of prior information and user interaction.

  15. Use of animal models for space flight physiology studies, with special focus on the immune system

    Science.gov (United States)

    Sonnenfeld, Gerald

    2005-01-01

    Animal models have been used to study the effects of space flight on physiological systems. The animal models have been used because of the limited availability of human subjects for studies to be carried out in space as well as because of the need to carry out experiments requiring samples and experimental conditions that cannot be performed using humans. Experiments have been carried out in space using a variety of species, and included developmental biology studies. These species included rats, mice, non-human primates, fish, invertebrates, amphibians and insects. The species were chosen because they best fit the experimental conditions required for the experiments. Experiments with animals have also been carried out utilizing ground-based models that simulate some of the effects of exposure to space flight conditions. Most of the animal studies have generated results that parallel the effects of space flight on human physiological systems. Systems studied have included the neurovestibular system, the musculoskeletal system, the immune system, the neurological system, the hematological system, and the cardiovascular system. Hindlimb unloading, a ground-based model of some of the effects of space flight on the immune system, has been used to study the effects of space flight conditions on physiological parameters. For the immune system, exposure to hindlimb unloading has been shown to results in alterations of the immune system similar to those observed after space flight. This has permitted the development of experiments that demonstrated compromised resistance to infection in rodents maintained in the hindlimb unloading model as well as the beginning of studies to develop countermeasures to ameliorate or prevent such occurrences. Although there are limitations to the use of animal models for the effects of space flight on physiological systems, the animal models should prove very valuable in designing countermeasures for exploration class missions of the future.

  16. Constitutive modeling of a nickel base superalloy -with a focus on gas turbine applications

    Energy Technology Data Exchange (ETDEWEB)

    Almroth, Per

    2003-05-01

    Gas turbines are used where large amounts of energy is needed, typically as engines in aircraft, ferries and power plants. From an efficiency point of view it is desirable to increase the service temperature as much as possible. One of the limiting factors is then the maximum allowable metal temperatures in the turbine stages, primarily in the blades of the first stage, that are exposed to the highest gas temperatures. Specially designed materials are used to cope with these severe conditions, such as the nickel base superalloy IN792. In order to be able to design the components for higher temperatures and tighter tolerances, a detailed understanding and computationel models of the material behaviour is needed. The models presented in this work have been developed with the objective of being physically well motivated, and with the intention of avoiding excessive numbers of parameters. The influence of the parameters should also be as easy as possible to interpret. The models are to describe the behaviour of IN792, under conditions typically found for a gas turbine blade. Specifically the high- and intermediate temperature isothermal modelling of IN792 have been addressed. One main issue when characterising the material and calibrating the models is the use of relevant tests, that are representative of component conditions. Therefore isothermal tests with an eye on the typical environment of a turbine blade have been planned and performed. Using numerical optimization techniques the material parameters for the isothermal behaviour of IN792 at 650 deg and 850 deg have been estimated. The good overall calibration results for these specific temperatures, using the presented modeling concept and nonstandard constitutive tests, suggests that the model can describe the behaviour of IN792 in gas turbine hot part applications.

    2017-11-01

    To outline differences in neurosurgical intervention (NI) rates between intracranial hemorrhage (ICH) types in mild traumatic brain injuries and help identify which ICH types are most likely to benefit from creation of predictive models for NI. A multicenter retrospective study of adult patients spanning 3 years at 4 U.S. trauma centers was performed. Patients were included if they presented with mild traumatic brain injury (Glasgow Coma Scale score 13-15) with head CT scan positive for ICH. Patients were excluded for skull fractures, "unspecified hemorrhage," or coagulopathy. Primary outcome was NI. Stepwise multivariable logistic regression models were built to analyze the independent association between ICH variables and outcome measures. The study comprised 1876 patients. NI rate was 6.7%. There was a significant difference in rate of NI by ICH type. Subdural hematomas had the highest rate of NI (15.5%) and accounted for 78% of all NIs. Isolated subarachnoid hemorrhages had the lowest, nonzero, NI rate (0.19%). Logistic regression models identified ICH type as the most influential independent variable when examining NI. A model predicting NI for isolated subarachnoid hemorrhages would require 26,928 patients, but a model predicting NI for isolated subdural hematomas would require only 328 patients. This study highlighted disparate NI rates among ICH types in patients with mild traumatic brain injury and identified mild, isolated subdural hematomas as most appropriate for construction of predictive NI models. Increased health care efficiency will be driven by accurate understanding of risk, which can come only from accurate predictive models. Copyright © 2017 Elsevier Inc. All rights reserved.

  18. Modeling Seismic Cycles of Great Megathrust Earthquakes Across the Scales With Focus at Postseismic Phase

    Science.gov (United States)

    Sobolev, Stephan V.; Muldashev, Iskander A.

    2017-12-01

    Subduction is substantially multiscale process where the stresses are built by long-term tectonic motions, modified by sudden jerky deformations during earthquakes, and then restored by following multiple relaxation processes. Here we develop a cross-scale thermomechanical model aimed to simulate the subduction process from 1 min to million years' time scale. The model employs elasticity, nonlinear transient viscous rheology, and rate-and-state friction. It generates spontaneous earthquake sequences and by using an adaptive time step algorithm, recreates the deformation process as observed naturally during the seismic cycle and multiple seismic cycles. The model predicts that viscosity in the mantle wedge drops by more than three orders of magnitude during the great earthquake with a magnitude above 9. As a result, the surface velocities just an hour or day after the earthquake are controlled by viscoelastic relaxation in the several hundred km of mantle landward of the trench and not by the afterslip localized at the fault as is currently believed. Our model replicates centuries-long seismic cycles exhibited by the greatest earthquakes and is consistent with the postseismic surface displacements recorded after the Great Tohoku Earthquake. We demonstrate that there is no contradiction between extremely low mechanical coupling at the subduction megathrust in South Chile inferred from long-term geodynamic models and appearance of the largest earthquakes, like the Great Chile 1960 Earthquake.

    Full Text Available Purpose - Blockchain is a distributed ledger, in which the blocks containing transaction details are connected chronologically to form a series of chains, thus raising the possibility of improving the process and innovating business model for the financial institutions. The purpose of this paper is to study the actual cases of Blockchain applied in Korea in 2017, so that a vision of business model innovation of financial institutions can be drawn. Design/methodology/approach - The financial institutions in Korea are in the technology verification stage to introduce Blockchain technology. Since there is an insufficient amount of actual measurement data, case study method was adopted. The authors interviewed ICT officers of major banks in Korea. The purpose of the interview was to understand the relationship between Blockchain and business models of financial institutions, and the effects and challenges that Blockchain has on the business model of financial institutions. Findings - From the perspective of financial institutions, the emergence of Blockchain does not just have technical significance – emergence of highly efficient database system – but has the possibility that if the business model of existing financial intermediaries disappears or get reduced, the financial services relying on them can disappear altogether, or some of them can be replaced, and financial transaction patterns of consumers can be changed. As a case studies researched for this paper, it was discovered that the distributed characteristic of Blockchain cannot be applied when actually developing financial services.

    2000-01-01

    Questioning how mathematics has evolved over the centuries and for what reasons; how human endeavour and changes in the way we live have been dependent on mathematics, this book tells the story of the impact this intellectual activity has had across cultures and civilizations. It shows how, far from being just the obsession of an elite group of philosophers, priests and scientists, mathematics has in some shape or other entered every area of human activity. The mysterious tally sticks of prehistoric peoples and the terrestial maps used for trade, exploration and warfare; the perennial fascination with the motions of heavenly bodies and changing perspectives on the art and science of vision; all are testament to a mathematics at the heart of history. The path of this changing discipline is marked by a wealth of images, from medieval manuscripts to the unsettling art of Dali or Duchamp, from the austere beauty of Babylonian clay tablets to the delicate complexity of computer-generated images.

    Full Text Available The purpose of this paper was to systematize the methodological experience acquired during the Psychomotricity and Intervention Project taught at Universidad Nacional, Costa Rica. This model of intervention aims at strengthening the different areas of human development in children ages 2 to 7, being perceptual-motor development and self-regulation the central axes. As a result of the implementation of this model children were able to become protagonists of their own learning.  They were exposed to different spaces and situations that, through movement, autonomy, analysis and resolution of situations, they were able to learn, face and improve daily tasks, skills and emotions.  The foregoing is according to the perception of the adult in charge of the child, project staff and the child’s own comments. It is concluded that the creation of this model is a contribution for professionals and the general community interested in children’s education and their overall formation.

  2. A closed-loop model of the respiratory system: focus on hypercapnia and active expiration.

    Directory of Open Access Journals (Sweden)

    Yaroslav I Molkov

    Full Text Available Breathing is a vital process providing the exchange of gases between the lungs and atmosphere. During quiet breathing, pumping air from the lungs is mostly performed by contraction of the diaphragm during inspiration, and muscle contraction during expiration does not play a significant role in ventilation. In contrast, during intense exercise or severe hypercapnia forced or active expiration occurs in which the abdominal "expiratory" muscles become actively involved in breathing. The mechanisms of this transition remain unknown. To study these mechanisms, we developed a computational model of the closed-loop respiratory system that describes the brainstem respiratory network controlling the pulmonary subsystem representing lung biomechanics and gas (O2 and CO2 exchange and transport. The lung subsystem provides two types of feedback to the neural subsystem: a mechanical one from pulmonary stretch receptors and a chemical one from central chemoreceptors. The neural component of the model simulates the respiratory network that includes several interacting respiratory neuron types within the Bötzinger and pre-Bötzinger complexes, as well as the retrotrapezoid nucleus/parafacial respiratory group (RTN/pFRG representing the central chemoreception module targeted by chemical feedback. The RTN/pFRG compartment contains an independent neural generator that is activated at an increased CO2 level and controls the abdominal motor output. The lung volume is controlled by two pumps, a major one driven by the diaphragm and an additional one activated by abdominal muscles and involved in active expiration. The model represents the first attempt to model the transition from quiet breathing to breathing with active expiration. The model suggests that the closed-loop respiratory control system switches to active expiration via a quantal acceleration of expiratory activity, when increases in breathing rate and phrenic amplitude no longer provide sufficient

    Researchers have recently applied evolutionary life history theory to the understanding of behaviors often conceived of as prosocial or antisocial. In addition, researchers have applied cognitive science to the understanding of substance use and used dual process models, where explicit cognitive processes are modeled as relatively distinct from implicit cognitive processes, to explain and predict substance use behaviors. In this paper we synthesized these two theoretical perspectives to produce an adaptive and cognitive framework for explaining substance use. We contend that this framework provides new insights into the nature of substance use that may be valuable for both clinicians and researchers.

Permutations of these were compared to adult-focused HIV testing coverage with condoms and TasP.The youth-focused strategy with ART treatment at diagnosis and condom use without adding interventions for HIV-negative youth performed better than the adult-focused strategy with adult testing reaching 50-60% coverage and TasP/condoms. Over the long term, the youth-focused strategy approached the performance of 70% adult testing and TasP/condoms. When high coverage male circumcision also is added to the youth-focused strategy, the combined intervention outperformed the adult-focused strategy with 70% testing, for at least 35 years by averting 94,000 more infections, averting 5.0 million more disability-adjusted life years (DALYs, and saving US$46.0 million over this period. The addition of prevention interventions beyond circumcision to the youth-focused strategy would be more beneficial if HIV care costs are high, or when program delivery costs are relatively high for programs encompassing HIV testing coverage exceeding 70%, TasP and condoms to HIV-infected adults compared to combination prevention programs among youth.For at least the next three decades, focusing in high burden settings on high coverage HIV testing, ART treatment upon

    Triple Diagonal (M) modeling is a technique to help quickly diagnose an organization`s existing production system and to identify significant improvement opportunities in executing, controlling, and planning operations. TD modeling is derived from ICAM Definition Language (IDEF 0)-also known as Structured Analysis and Design Technique. It has been used successfully at several Department of Defense remanufacturing facilities trying to accomplish significant production system modernization. TD has several advantages over other modeling techniques. First, it quickly does ``As-ls`` analysis and then moves on to identify improvements. Second, creating one large diagram makes it easier to share the TD model throughout an organization, rather than the many linked 8 1/2 {times} 11`` drawings used in traditional decomposition approaches. Third, it acts as a communication mechanism to share understanding about improvement opportunities that may cross existing functional/organizational boundaries. Finally, TD acts as a vehicle to build a consensus on a prioritized list of improvement efforts that ``hangs togethers as an agenda for systemic changes in the production system and the improved integration of support functions.

    In this study, an improved and complete secondary organic aerosols (SOA) chemistry scheme was implemented in the CHIMERE model. The implementation of isoprene chemistry for SOA significantly improves agreement between long series of simulated and observed particulate matter concentrations. While simulated organic carbon concentrations are clearly improved at elevated sites by adding the SOA scheme, time correlation are impaired at low level sites in Portugal, Italy and Slovakia. At several sites a clear underestimation by the CHIMERE model is noticed in wintertime possibly due to missing wood burning emissions as shown in previous modeling studies. In Europe, the CHIMERE model gives yearly average SOA concentrations ranging from 0.5 μg m -3 in the Northern Europe to 4 μg m -3 over forested regions in Spain, France, Germany and Italy. In addition, our work suggests that during the highest fire emission periods, fires can be the dominant source of primary organic carbon over the Mediterranean Basin, but the SOA contribution from fire emissions is low. Isoprene chemistry has a strong impact on SOA formation when using current available kinetic schemes. (authors)

    2017-07-19

    We constructed a model explaining families' positive adaptation in chronic crisis situations such as the problematic behavior of elderly patients with dementia and attendant caregiving stress, based on the family resilience model. Our aim was to devise an adaptation model for families of elderly patients with dementia. A survey of problematic behavior in elderly patients with dementia, family stress, family resilience, and family adaptation was conducted with 292 consenting individuals. The collected data were analyzed using structural equation modeling. The communication process, family stress, and problematic behavior of elderly patients with dementia had direct and indirect effects on family adaptation, while belief system, organization pattern, and social support had indirect effects. Specifically, family stress and more severe problematic behavior by elderly patients with dementia negatively influenced family adaptation, while greater family resilience improved such adaptation. Interventions aiming to enhance family resilience, based on the results of this study, are required to help families with positive adaptation. Such family programs might involve practical support such as education on the characteristics of elderly persons with dementia and coping methods for their problematic behavior; forming self-help groups for families; revitalizing communication within families; and activating communication channels with experts.

  1. Focused modelling. Fracture identification in Olkiluoto borehole OL-KR04

    International Nuclear Information System (INIS)

    Jokinen, J.; Jakobsson, K.

    2004-10-01

    An extensive set of measured borehole data has been obtained from geological repository investigations in the bedrock of Olkiluoto. Our hypothesis is that geophysical data may be used more efficiently to identify and classify fracture zones. It is known that several geophysical logging methods yield useful information outside the borehole walls that cannot be reached otherwise. At present, this data is used for additional fracture characterization but not for identification purposes. The study focuses on the application of 14 different geophysical data measured in the borehole OL-KR04. The whole data set is divided into main groups using the Principal Component Analysis (PCA). Each group is composed mainly of sensitive methods detecting specific physical characteristics. The main groups from the geophysical point of view are open fractures, reduced density, increased electrical conductivity, and increased natural radiation. The Varimax optimization method is used to maximize the importance of supporting data as well as to emphasize differences between the discovered principal components. In fracture zone analysis, drilling core samples and the hydrological measurement results form an indispensable data set. For practical reasons, and in order to fulfill the requirements of the PCA analysis, S-wave velocity and electrical resistivity measurements are also performed. A combination of these methods, simultaneously applied using suitable 'trigger limits', identifies penetrated extensive fracture sections in a borehole cost-effectively and unambiguously. (orig.)

    This thesis deals mainly with computer simulations of wood-drying distortions, especially twist. The reason for this is that such distortions often appear in dried timber, and the results are quality downgrades and thus value losses in the wood value chain. A computer simulation is a way to theoretically simulate what happens in reality when moisture content in timber changes. If the computer simulation model is appropriate and capable of realistic simulations of real events, then it is possi...

    Adenosine is an endogenous modulator exerting its functions through the activation of four adenosine receptor (AR) subtypes, termed A₁, A 2A , A 2B and A₃, which belong to the G protein-coupled receptor (GPCR) superfamily. The human A₃AR (hA₃AR) subtype is implicated in several cytoprotective functions. Therefore, hA₃AR modulators, and in particular agonists, are sought for their potential application as anti-inflammatory, anticancer, and cardioprotective agents. Structure-based molecular modeling techniques have been applied over the years to rationalize the structure-activity relationships (SARs) of newly emerged A₃AR ligands, guide the subsequent lead optimization, and interpret site-directed mutagenesis (SDM) data from a molecular perspective. In this review, we showcase selected modeling-based and guided strategies that were applied to elucidate the binding of agonists to the A₃AR and discuss the challenges associated with an accurate prediction of the receptor extracellular vestibule through homology modeling from the available X-ray templates.

    For a fire safety analysis, in order to comply with nuclear safety goals, a nuclear fuel facility operator has to define the elements important for safety to be maintained, even in the case of a fire. One of the key points of this fire analysis is the assessment of possible fire scenarios in the facility. This paper presents the IRSN method applied to a case study to assess fire scenarios which have the most harmful effects on safety targets. The layout consists in a central room (fire cell) containing three glove boxes with radioactive material and three electrical cabinets. This room is linked to two connecting compartments (the fire cell and these two compartments define the containment cell) and then to two corridors. Each room is equipped with a mechanical ventilation system, and a pressure cascade is established from the corridors to the central room. A fire scenario was studied with fire ignition occurring in an electrical cabinet. This scenario has a set of safety goals (prevention of fire cell and containment device failure, propagation of the fire). This case study was conducted with the IRSN code SYLVIA based on two zones modelling. Safety goals were associated with key parameters and performance criteria to be fulfilled. Modelling assumptions were defined in order to maximize physical effects of the fire. Sensitivity studies were also conducted on key parameters such as oxygen limitation, equivalent-fuel definition. Eventually, a critical analysis of the code models was carried out.

    2015-01-01

    Current models of dielectric elastomer actuators (DEAs) are mostly constrained to first principal descriptions that are not well suited to the application of control design due to their computational complexity. In this work we describe an integrated framework for the identification of control focused, data driven and time-varying DEA models that allow advanced analysis of nonlinear system dynamics in the frequency-domain. Experimentally generated input–output data (voltage-displacement) was used to identify control-focused, nonlinear and time-varying dynamic models of a set of film-type DEAs. The model description used was the nonlinear autoregressive with exogenous input structure. Frequency response analysis of the DEA dynamics was performed using generalized frequency response functions, providing insight and a comparison into the time-varying dynamics across a set of DEA actuators. The results demonstrated that models identified within the presented framework provide a compact and accurate description of the system dynamics. The frequency response analysis revealed variation in the time-varying dynamic behaviour of DEAs fabricated to the same specifications. These results suggest that the modelling and analysis framework presented here is a potentially useful tool for future work in guiding DEA actuator design and fabrication for application domains such as soft robotics.

  9. Investigation of cellular and molecular responses to pulsed focused ultrasound in a mouse model.

    Directory of Open Access Journals (Sweden)

    Scott R Burks

    Full Text Available Continuous focused ultrasound (cFUS has been widely used for thermal ablation of tissues, relying on continuous exposures to generate temperatures necessary to induce coagulative necrosis. Pulsed FUS (pFUS employs non-continuous exposures that lower the rate of energy deposition and allow cooling to occur between pulses, thereby minimizing thermal effects and emphasizing effects created by non-thermal mechanisms of FUS (i.e., acoustic radiation forces and acoustic cavitation. pFUS has shown promise for a variety of applications including drug and nanoparticle delivery; however, little is understood about the effects these exposures have on tissue, especially with regard to cellular pro-homing factors (growth factors, cytokines, and cell adhesion molecules. We examined changes in murine hamstring muscle following pFUS or cFUS and demonstrate that pFUS, unlike cFUS, has little effect on the histological integrity of muscle and does not induce cell death. Infiltration of macrophages was observed 3 and 8 days following pFUS or cFUS exposures. pFUS increased expression of several cytokines (e.g., IL-1α, IL-1β, TNFα, INFγ, MIP-1α, MCP-1, and GMCSF creating a local cytokine gradient on days 0 and 1 post-pFUS that returns to baseline levels by day 3 post-pFUS. pFUS exposures induced upregulation of other signaling molecules (e.g., VEGF, FGF, PlGF, HGF, and SDF-1α and cell adhesion molecules (e.g., ICAM-1 and VCAM-1 on muscle vasculature. The observed molecular changes in muscle following pFUS may be utilized to target cellular therapies by increasing homing to areas of pathology.

The dihydrate form of azithromycin is also discussed. The azithromycin (i.e. Sumamed and Zithromax story, which dates from the second half of the last century, can be considered as the first and foremost example of successful knowledge and technology transfer in Croatia ever. On their web pages, the World Intellectual Property Organization (WIPO reports the PLIVA azithromycin story as a case study and excellent example of proactive licensing strategy. For the discovery of azithromycin, in addition to receiving numerous awards, in the year 2000, PLIVA's scientists D. Sc. S. Đokić and M. Sc. G. Kobrehel, together with the representatives from the US-based Pfizer, were granted the honorable titles of "Heroes of Chemistry 2000" by the American Chemical Society (ACS, a non-profit association of American chemists and chemical engineers, and the largest association of scientists in the world. This high award is rightly taken to be also recognition of the achievement of PLIVA's entire team working on azithromycin. The success of azithromycin has placed PLIVA among the few pharmaceutical companies in the world that have developed their own blockbuster drug, and has entitled Croatia to join a small group of nations that have developed a new antibiotic.

    A theoretical model is established using Rayleigh-Sommerfeld diffraction theory to describe the diffraction focusing characteristics of low F-number diffractive optical elements with continuous relief fabricated by laser direct writing, and continuous-relief diffractive optical elements with a design wavelength of 441.6nm and a F-number of F/4 are fabricated and measured to verify the validity of the diffraction focusing model. The measurements made indicate that the spot size is 1.75mum and the diffraction efficiency is 70.7% at the design wavelength, which coincide well with the theoretical results: a spot size of 1.66mum and a diffraction efficiency of 71.2%.

    This paper presents a comparison between measured and simulated tower loads for the Danish offshore wind farm Nysted 2. Previously, only limited full scale experimental data containing tower load measurements have been published, and in many cases the measurements include only a limited range of wind speeds. In general, tower loads in wake conditions are very challenging to predict correctly in simulations. The Nysted project offers an improved insight to this field as six wind turbines located in the Nysted II wind farm have been instrumented to measure tower top and tower bottom moments. All recorded structural data have been organized in a database, which in addition contains relevant wind turbine SCADA data as well as relevant meteorological data - e.g. wind speed and wind direction - from an offshore mast located in the immediate vicinity of the wind farm. The database contains data from a period extending over a time span of more than 3 years. Based on the recorded data basic mechanisms driving the increased loading experienced by wind turbines operating in offshore wind farm conditions have been identified, characterized and modeled. The modeling is based on the Dynamic Wake Meandering (DWM) approach in combination with the state-of-the-art aeroelastic model HAWC2, and has previously as well as in this study shown good agreement with the measurements. The conclusions from the study have several parts. In general the tower bending and yaw loads show a good agreement between measurements and simulations. However, there are situations that are still difficult to match. One is tower loads of single-wake operation near rated ambient wind speed for single wake situations for spacing’s around 7-8D. A specific target of the study was to investigate whether the largest tower fatigue loads are associated with a certain downstream distance. This has been identified in both simulations and measurements, though a rather flat optimum is seen in the measurements.

  13. Creation Stories: Myths about the Origin of Money

    A myth about the origins of money has long organized modern approaches to the medium. According to that creation story, money is the natural product of human exchange. It can be analogized to a commodity like silver that comes to hand out of the decentralized activity of trading or a convention like language that arises out of a consensus about the value of an item. But if we consider clues about money’s origins and extrapolate from its continuing practice, another story comes into focus. It ...

  14. The Wellenberg story

    International Nuclear Information System (INIS)

    Untensperger, Marcel A.

    1995-01-01

    In June 1994 two-thirds of the voters present at a community meeting in Wolfenschiessen agreed to host a repository for short-lived low- and intermediate-level (LLW/ILW) waste in the nearby Wellenberg mountain. Wolfenschiessen, located in a farming region in central Switzerland, is a village of 1900 residents. Nagra, the Swiss National Cooperative for the Disposal of Radioactive Waste, was able to celebrate a breakthrough at last. Nuclear opponents criticised that the community had, essentially, been bought by Nagra. But agreements for free electricity, grants and annual payments only represented the culmination of a decade of intense effort by Nagra towards winning local public acceptance for its repository. The host community came to trust Nagra for what we are - a technical service organisation with a federal mandate but with no political power. As a matter of fact, Nagra has encountered much more opposition than acceptance over the years. Our scientists were greeted by residents carrying pitchforks and sticks when attempting to begin experimental field work at one site; due to exhaustive use of Swiss democratic rights, permission to drill at another site was delayed by opponents for eight years. What did Nagra learn from all these obstacles? On its way towards gaining public acceptance, Nagra was confronted with problems in three areas: Fear and safety, NIMBY-syndrome (not in my backyard); Manipulation of public anxiety for individual political gain and as a substratum for arguments against nuclear power. While we at Nagra concede that Wellenberg represents a 'green light', we also know that not all lights ahead will be green. Some will be amber. Is the Wellenberg story one of success? The future will tell us, but a few doors have been opened along the way towards realising a repository for short-lived LLW/ILW in Switzerland

    Autism spectrum disorder (ASD) is gathering concerns in socially developed countries. ASD is a neuropsychiatric disorder of genetic origin with high prevalence of 1%-2%. The patients with ASD characteristically show impaired social skills. Today, many genetic studies identify numerous susceptible genes and genetic loci associated with ASD. Although some genetic factors can lead to abnormal brain function linked to ASD phenotypes, the pathogenic mechanism of ASD is still unclear. Here, we discuss a new mouse model for ASD as an advanced tool to understand the mechanism of ASD.

    We consider a model problem for the research of Earth’s surface state caused by discharge of tectonic stress on the deep cracks in the earth’s crust. Using the numerical method of bicharacteristics, algorithm is developed and solution of the problem of non-stationary dynamics of a homogeneous isotropic elastic half-space is built under plane strain when one resets the vertical stress on crack. Diffraction of waves on the surface is studied, pictures of wave fields and stress-strain state of the medium and the surface for different moments of time are built.

    To determine the optimum position to center a small-aperture corneal inlay and the effect of residual defocus in the surgical eye to maximize depth of focus. Laboratorio de Óptica, Universidad de Murcia, Murcia, Spain. Cohort study. Personalized eye models were built using actual data (corneal topography, eye length, ocular aberrations, and eye alignment). A small aperture 1.6 mm in diameter was placed at the corneal plane in each model. The monochromatic and polychromatic Strehl ratios were calculated as a function of the pinhole position. Different residual defocus values were also incorporated into the models, and the through-focus Strehl ratios were calculated. Sixteen eye models were built. For most subjects, the optimum location of the aperture for distance vision was close to the corneal reflex position. For a given optimized centration of the aperture, the best compromise of depth of focus was obtained when the eyes had some residual myopic defocus (range -0.75 to -1.00 diopter [D]). Strehl ratio values were over 0.1 for far distance, which led to visual acuities better than 20/20. The depth of focus was 2.50 D with a mean near visual acuity of Jaeger 1 or better. In eyes with little astigmatism and aberrations, the optimum centration of the small aperture was near the corneal reflex position. To improve optical outcomes with the inlay, some small residual myopia and correction of corneal astigmatism might be required. Copyright © 2011 ASCRS and ESCRS. Published by Elsevier Inc.

    Full Text Available In this review, we discuss insights gained through the use of stem cell preparations regarding the modeling of neurological diseases, the need for aging neurons derived from pluripotent stem cells to further advance the study of late-onset adult neurological diseases, and the extent to which mechanisms linked to the mismanagement of ROS. The context of these issues can be revealed using the three disease states of Parkinson’s (PD, Alzheimer’s (AD, and schizophrenia, as considerable insights have been gained into these conditions through the use of stem cells in terms of disease etiologies and the role of oxidative stress. The latter subject is a primary area of interest of our group. After discussing the molecular models of accelerated aging, we highlight the role of ROS for the three diseases explored here. Importantly, we do not seek to provide an extensive account of all genetic mutations for each of the three disorders discussed in this review, but we aim instead to provide a conceptual framework that could maximize the gains from merging the approaches of stem cell microsystems and the study of oxidative stress in disease in order to optimize therapeutics and determine new molecular targets against oxidative stress that spare stem cell proliferation and development.

    This study was conducted to assess predictor variables of husbands in multicultural families and examine the relationship among variables after setting up a hypothetical model including influencing factors, so as to provide a framework necessary for developing nursing interventions of domestic violence. The participants were 260 husbands in multicultural families in four cities in Korea. Data were analyzed using SPSS 22.0 and AMOS 20.0. Self-control, social support, family of origin violence experience and stress on cultural adaptation directly affected to dysfunctional communication, and the explanatory power of the variables was 64.7%. Family of origin violence experience in domestic stress on cultural adaptation, and dysfunctional communication were directly related to domestic violence in multicultural families, and the explanatory power of the variables was 64.6%. We found out that all variables in the model had mediation effects to domestic violence through dysfunctional communication. In other words, self-control and social support had complete mediation effects, and family of origin violence experience in domestic violence and stress on cultural adaptation had partial mediation effects. The variables explained in this study should be considered as predictive factors of domestic violence in multicultural families, and used to provide preventive nursing intervention. Our resutls can be taken into account for developing and implementing programs on alleviating dysfunctional communication in multicultural families in Korea. Copyright © 2016.

    Fukushima Daiichi nuclear power plant of Tokyo Electric Power Company is facing contaminated water issues in the aftermath of the Great East Japan Earthquake on March 11, 2011. The amount of contaminated water is continuously increasing due to groundwater leakage into the underground part of reactor and turbine buildings. Therefore, it is important to understand the groundwater flow conditions at the site and to predict the impact of countermeasures taken for isolating groundwater from the source of the contamination, i.e. the reactor buildings. Installations, such as of land-side and sea-side impermeable walls have been planned as countermeasures. In this study, groundwater flow modeling has been performed to estimate the response of groundwater flow conditions to the countermeasures. From the modeling, groundwater recharge and discharge areas, major groundwater flow direction, inflow rate into underground part of the buildings, and changes in response to implementation of the countermeasures could be reasonably estimated. The results indicate that the countermeasures will decrease the volume of inflow into the underground part of the buildings. This means that the countermeasures will be effective in reducing the discharge volume of contaminated groundwater to ocean. (author)

    Ageing is the organisms increased susceptibility to death, which is linked to accumulated damage in the cells and tissues. Ageing is a complex process regulated by crosstalk of various pathways in the cells. Ageing is highly regulated by the Target of Rapamycin (TOR) pathway activity. TOR is an evolutionary conserved key protein kinase in the TOR pathway that regulates growth, proliferation and cell metabolism in response to nutrients, growth factors and stress. Comparing the ageing process in invertebrate model organisms with relatively short lifespan with mammals provides valuable information about the molecular mechanisms underlying the ageing process faster than mammal systems. Inhibition of the TOR pathway activity via either genetic manipulation or rapamycin increases lifespan profoundly in most invertebrate model organisms. This contribution will review the recent findings in invertebrates concerning the TOR pathway and effects of TOR inhibition by rapamycin on lifespan. Besides some contradictory results, the majority points out that rapamycin induces longevity. This suggests that administration of rapamycin in invertebrates is a promising tool for pursuing the scientific puzzle of lifespan prolongation. Copyright © 2016 Elsevier Ireland Ltd.

    The required plasma parameters of krypton and xenon at different temperatures were calculated, the x-ray emission properties of plasmas were studied, and based on the corona model the suitable temperature range for generating H-like and He-like ions (therefore soft x-ray emissions) of different gases plasma were found. The code is applied to characterize the plasma focus in different plasma focus devices, and for optimizing the nitrogen, oxygen, neon, argon, krypton and xenon soft x-ray yields based on bank, tubes and operating parameters. It is found that t he soft x-ray yield increases with changing pressure until it reaches the maximum value for each plasma focus device. Keeping the bank parameters, operational voltage unchanged but systematically changing other parameters, numerical experiments were performed finding the optimum combination of Po, z0 and 'a' for the maximum soft x-ray yield. Thus we expect to increase the soft x-ray yield of plasma focus device several-fold from its present typical operation; without changing the capacitor bank, merely by changing the electrode configuration and the operating pressure. The Lee model code was also used to run numerical experiments on plasma focus devices for optimizing soft x-ray yield with reducing Lo, varying z0 and 'a' to get engineering designs with maximum soft x-ray yield for these devices at different experimental conditions and gases. Numerical experiments showed the influence of the gas used in plasma focus and its propor ties on soft x-ray emission and its propor ties and then on its applications. Scaling laws for soft x-ray of nitrogen, oxygen, neon, argon, krypton and xenon plasma focus in terms of energy, peak discharge current and focus pinch current were found. Radiative cooling effects are studied indicating that radiative collapse may be observed for heavy noble gases (Ar, Kr, Xe) for pinch currents even below 100 k A. The results show that the line radiation emission and

  9. Wingless Flight: The Lifting Body Story

    1997-01-01

    Wingless Flight tells the story of the most unusual flying machines ever flown, the lifting bodies. It is my story about my friends and colleagues who committed a significant part of their lives in the 1960s and 1970s to prove that the concept was a viable one for use in spacecraft of the future. This story, filled with drama and adventure, is about the twelve-year period from 1963 to 1975 in which eight different lifting-body configurations flew. It is appropriate for me to write the story, since I was the engineer who first presented the idea of flight-testing the concept to others at the NASA Flight Research Center. Over those twelve years, I experienced the story as it unfolded day by day at that remote NASA facility northeast of los Angeles in the bleak Mojave Desert. Benefits from this effort immediately influenced the design and operational concepts of the winged NASA Shuttle Orbiter. However, the full benefits would not be realized until the 1990s when new spacecraft such as the X-33 and X-38 would fully employ the lifting-body concept. A lifting body is basically a wingless vehicle that flies due to the lift generated by the shape of its fuselage. Although both a lifting reentry vehicle and a ballistic capsule had been considered as options during the early stages of NASA's space program, NASA initially opted to go with the capsule. A number of individuals were not content to close the book on the lifting-body concept. Researchers including Alfred Eggers at the NASA Ames Research Center conducted early wind-tunnel experiments, finding that half of a rounded nose-cone shape that was flat on top and rounded on the bottom could generate a lift-to-drag ratio of about 1.5 to 1. Eggers' preliminary design sketch later resembled the basic M2 lifting-body design. At the NASA Langley Research Center, other researchers toyed with their own lifting-body shapes. Meanwhile, some of us aircraft-oriented researchers at the, NASA Flight Research Center at Edwards Air

    2014-12-01

    Full Text Available Fertilization is a cell biological phenomenon of crucial importance for the birth of new life in a variety of multicellular and sexual reproduction species such as algae, animal and plants. Fertilization involves a sequence of events, in which the female gamete “egg” and the male gamete “spermatozoon (sperm” develop, acquire their functions, meet and fuse with each other, to initiate embryonic and zygotic development. Here, it will be briefly reviewed how oocyte cytoplasmic components are orchestrated to undergo hormone-induced oocyte maturation and sperm-induced activation of development. I then review how sperm-egg membrane interaction/fusion and activation of development in the fertilized egg are accomplished and regulated through egg coat- or egg plasma membrane-associated components, highlighting recent findings and future directions in the studies using Xenopus laevis as a model experimental animal.

    Full Text Available Target costing by integrating customer requirements, technical attributes and cost information into the product design phase and eliminating the non-value added functions, plays a vital role in different phases of the product life cycle. Quality Function Deployment (QFD and Value Engineering (VE are two techniques which can be used for applying target costing, successfully. The purpose of this paper is to propose an integrated model of target costing, QFD and VE to explore the role of target costing in managing product costs while promoting quality specifications meeting customers’ needs. F indings indicate that the integration of target costing, QFD and VE is an essential technique in managing the costs of production process. Findings also imply that integration of the three techniques provides a competitive cost advantage to companies.

    The health benefits of exercise in school are recognized, yet physical activity continues to decline during early adolescence despite numerous interventions. In this study, we investigated whether the prototype willingness model, an account of adolescent decision making that includes both reasoned behavioral choices and unplanned responses to social environments, might improve understanding of physical activity in school. We conducted focus groups with British pupils aged 12 to 13 years and used deductive thematic analysis to search for themes relating to the model. Participants described reasoned decisions about physical activity outside school and unplanned choices to be inactive during break, in response to social contexts described as more "judgmental" than in primary school. Social contexts appeared characterized by anxiety about competence, negative peer evaluation, and inactive playground norms. The prototype willingness model might more fully explain physical activity in school than reasoned behavioral models alone, indicating potential for interventions targeting anxieties about playground social environments.

    Zhu, Juner; Wierzbicki, Tomasz; Li, Wei

    2018-02-01

    We are rapidly approaching an inflection point in the adoption of electric vehicles on the roads. All major automotive companies are having well-funded plans for mass market affordable branded EV product line models, which can open the floodgates. A rapid growth of battery energy density, accompanied by an aggressive progress of reduction of costs of lithium-ion batteries, brings safety concerns. While more energy stored in the battery pack of an EV translates to a longer range, the downside is that accidents will be more violent due to battery inevitable explosion. With today's technology, severe crashes involving intrusion into the battery pack will potentially result in a thermal runaway, fire, and explosion. Most of research on lithium-ion batteries have been concerned with the electrochemistry of cells. However, in most cases failure and thermal runaway is caused by mechanical loading due to crash events. There is a growing need to summarize the already published results on mechanical loading and response of batteries and offer a critical evaluation of work in progress. The objective of this paper is to present such review with a discussion of many outstanding issues and outline of a roadmap for future research.

  17. A MAGNETOHYDRODYNAMIC MODEL FOCUSED ON THE CONFIGURATION OF MAGNETIC FIELD RESPONSIBLE FOR A SOLAR PENUMBRAL MICROJET

    International Nuclear Information System (INIS)

    Magara, T.

    2010-01-01

    In order to understand the configuration of magnetic field producing a solar penumbral microjet that was recently discovered by Hinode, we performed a magnetohydrodynamic simulation reproducing a dynamic process of how that configuration is formed in a modeled solar penumbral region. A horizontal magnetic flux tube representing a penumbral filament is placed in a stratified atmosphere containing the background magnetic field that is directed in a relatively vertical direction. Between the flux tube and the background field there forms the intermediate region in which the magnetic field has a transitional configuration, and the simulation shows that in the intermediate region magnetic reconnection occurs to produce a clear jet-like structure as suggested by observations. The result that a continuous distribution of magnetic field in three-dimensional space gives birth to the intermediate region producing a jet presents a new view about the mechanism of a penumbral microjet, compared to a simplistic view that two field lines, one of which represents a penumbral filament and the other the background field, interact together to produce a jet. We also discuss the role of the intermediate region in protecting the structure of a penumbral filament subject to microjets.

  18. From quantum to classical modeling of radiation reaction: A focus on stochasticity effects

    2018-04-01

    Radiation reaction in the interaction of ultrarelativistic electrons with a strong external electromagnetic field is investigated using a kinetic approach in the nonlinear moderately quantum regime. Three complementary descriptions are discussed considering arbitrary geometries of interaction: a deterministic one relying on the quantum-corrected radiation reaction force in the Landau and Lifschitz (LL) form, a linear Boltzmann equation for the electron distribution function, and a Fokker-Planck (FP) expansion in the limit where the emitted photon energies are small with respect to that of the emitting electrons. The latter description is equivalent to a stochastic differential equation where the effect of the radiation reaction appears in the form of the deterministic term corresponding to the quantum-corrected LL friction force, and by a diffusion term accounting for the stochastic nature of photon emission. By studying the evolution of the energy moments of the electron distribution function with the three models, we are able to show that all three descriptions provide similar predictions on the temporal evolution of the average energy of an electron population in various physical situations of interest, even for large values of the quantum parameter χ . The FP and full linear Boltzmann descriptions also allow us to correctly describe the evolution of the energy variance (second-order moment) of the distribution function, while higher-order moments are in general correctly captured with the full linear Boltzmann description only. A general criterion for the limit of validity of each description is proposed, as well as a numerical scheme for the inclusion of the FP description in particle-in-cell codes. This work, not limited to the configuration of a monoenergetic electron beam colliding with a laser pulse, allows further insight into the relative importance of various effects of radiation reaction and in particular of the discrete and stochastic nature of high

    Panattoni, Katherine; Thomsen, Dorthe Kirkegaard

    2018-06-12

    In this paper, we examined relationships and differences between personal and vicarious life stories, i.e., the life stories one knows of others. Personal and vicarious life stories of both members of 51 young couples (102 participants), based on McAdams' Life Story Interview (2008), were collected. We found significant positive relationships between participants' personal and vicarious life stories on agency and communion themes and redemption sequences. We also found significant positive relationships between participants' vicarious life stories about their partners and those partners' personal life stories on agency and communion, but not redemption. Furthermore, these relationships were not explained by similarity between couples' two personal life stories, as no associations were found between couples' personal stories on agency, communion and redemption. These results suggest that the way we construct the vicarious life stories of close others may reflect how we construct our personal life stories.

    2018-03-01

    The present study constructed a preliminary process model of corrective emotional experience (CEE) in an integrative affect-focused therapy. Task analysis was used to analyse 6 in-session events taken from 6 Japanese clients who worked with an integrative affect-focused therapist. The 6 events included 3 successful CEEs and 3 partially successful CEEs for comparison. A rational-empirical model of CEE was generated, which consisted of two parallel client change processes, intrapersonal change and interpersonal change, and the therapist interventions corresponding to each process. Therapist experiential interventions and therapist affirmation facilitated both intrapersonal and interpersonal change processes, whereas his relational interventions were associated with the interpersonal change process. The partially successful CEEs were differentiated by the absence of the component of core painful emotions or negative beliefs in intrapersonal change process, which seemed crucial for the interpersonal change process to develop. CEE is best represented by a preliminary model that depicts two parallel yet interacting change processes. Intrapersonal change process is similar to the sequence of change described by the emotional processing model (Pascual-Leone & Greenberg, ), whereas interpersonal change process is a unique contribution of this study. Interpersonal change process was facilitated when the therapist's active stance and use of immediacy responses to make their relational process explicit allowed a shared exploration. Therapist affirmation bridged intrapersonal change to interpersonal change by promoting an adaptive sense of self in clients and forging a deeper emotional connection between the two.

  1. The Path Tells a Story

    Nack, Frank

    Stories have been shared in every culture because they are a powerful means to entertain, educate, and preserve traditions or instill values. In the history of storytelling technological evolution has changed the tools available to storytellers, from primarily oral representations that have been enriched with gestures and expressions to the sophisticated forms we enjoy today, such as film or complex layered hypermedia environments. Despite these developments the traditional linear presentation of a story is still the most dominant. Yet, the first decade of the twenty-first century established a technology that finally, after many attempts, can challenge the dogma of passive linearity. It is mobile technology that makes people aware that a digital environment opens opportunities to everybody to freely socialize through and with stories relevant for the current spatial, temporal, and social context.

  2. The novel as short story

    Directory of Open Access Journals (Sweden)

    Kirk Schlueter

    2013-06-01

    Full Text Available In recent history, the novel has been thought of and defined primarily as a long prose narrative. However, this has not been the case historically, as the original meaning of "novel" was for "a piece of news" or "a short story or novella." Returning to this original definition, I propose a new way of viewing the work known contemporarily as the novel as a collection, or sequence, of united short stories rather than a single indivisible work, with the component short stories or novellas comprising the sequence renamed as "novels." A brief examination of several classic works traditionally considered novels serves to illustrate how this change in definition will affect reading.

    A professional career may extend over a period of 40 years. Although learning is a feature of professional competence, little is known about learning and development after professional entry education. Narrative inquiry was used to understand how physiotherapists learned and developed over time, and stories from a purposeful sample of 12 physiotherapists were collected. Stories were thematically analyzed with regard to key elements related to learning and development, and common themes were identified across stories. Four themes emerged from the analysis where physiotherapists learned and developed in working life: (1) facing challenges; (2) contrasting perspectives; (3) drawing on hundreds of educators; and (4) building on personal experience. Non-formal ways of learning in working life may help physiotherapists learn and develop confidence, communication strategies and different approaches to treatment. Besides reflection on personal experience and patient encounters, learning and development may be promoted and supported by taking on challenges and changing settings.

    Particle ray tracing through simulated 3D magnetic fields was executed to investigate the effective quadrupole strength of the edge focusing of the rectangular bending magnets in the Los Alamos Proton Storage Ring (PSR). The particle rays receive a kick in the edge field of the rectangular dipole. A focal length may be calculated from the particle tracking and related to the fringe field integral (FINT) model parameter. This tech note introduces the baseline lattice model of the PSR and motivates the need for an improvement in the baseline model's vertical tune prediction, which differs from measurement by .05. An improved model of the PSR is created by modifying the fringe field integral parameter to those suggested by the ray tracing investigation. This improved model is then verified against measurement at the nominal PSR operating set point and at set points far away from the nominal operating conditions. Lastly, Linear Optics from Closed Orbits (LOCO) is employed in an orbit response matrix method for model improvement to verify the quadrupole strengths of the improved model.

    Although predicting temperature variation is important for designing treatment plans for thermal therapies, research in this area is yet to investigate the applicability of prevalent thermal conduction models, such as the Pennes equation, the thermal wave model of bio-heat transfer, and the dual phase lag (DPL) model. To address this shortcoming, we heated a tissue phantom and ex vivo bovine liver tissues with focused ultrasound (FU), measured the temperature response, and compared the results with those predicted by these models. The findings show that, for a homogeneous-tissue phantom, the initial temperature increase is accurately predicted by the Pennes equation at the onset of FU irradiation, although the prediction deviates from the measured temperature with increasing FU irradiation time. For heterogeneous liver tissues, the predicted response is closer to the measured temperature for the non-Fourier models, especially the DPL model. Furthermore, the DPL model accurately predicts the temperature response in biological tissues because it increases the phase lag, which characterizes microstructural thermal interactions. These findings should help to establish more precise clinical treatment plans for thermal therapies.

    As advertising becomes more crucial to video games' success, developers risk promoting their products beyond the features that they can actually include. For features of interactive storytelling, the effects of making such exaggerations are not well known, as reports from industry have been anecdotal at best. In this paper, we explore the effects of making exaggerated claims for interactive stories, in the context of the theory of advertising. Results from a human user study show that female players find linear and branching stories to be significantly less enjoyable when they are advertised with exaggerated claims.

    Full Text Available Recontar histórias é uma atividade complexa que envolve recursos da memória de curta duração (MCD e da memória episódica (ME. Estratégias direcionadas a objetivos e intenções particulares diminuem a sobrecarga da MCD e ativam a ME. Com o objetivo de estudar a influência do envelhecimento nestes mecanismos, estudamos o relato de uma história por dois grupos de adultos: 17 com 30 a 55 anos e 14 com mais de 60 anos. Os adultos mais jovens lembraram mais proposições do que os idosos, mas ambos grupos relembraram melhor as macroestruturas do que as microestruturas e não foi encontrada diferença no número de inferências, interferências e reconstruções. Entretanto, uma análise de ênfases dados à história, mostrou que jovens preferem relatar a seqüência de ações e idosos, encadeam os fatos de forma subjetiva, sugerindo que, devido à uma redução da memória de trabalho, utilizam-se mais das estratégias que recorrem às informações armazenadas na memória episódica, deixando transparecer suas representações mentais.Text comprehension is a complex activity that requires resources from short term memory (STM and from episodic memory (EM. Strategies directed to goals and intentions avoid an overload of the STM and activates the EM. To study the influence of aging on those mechanisms, we analyzed the recall of a story by two different groups of adults: 17 subjects, 30 to 50 years old, and 14 with more than 60 years of age. The younger group remembered more propositions than the elders, but both groups recalled better the macro than the microstructure. No differences regarding number of inference, interference, and reconstruction were found. Nevertheless, residual analysis showed that younger adults organized their recall telling the actions of the original story, whereas the older adults chose a subjective organization of the main facts, suggesting that due to a reduction of the working memory, the elderly elaborated

    Full Text Available  Abstract Manije and Bijan story, a poem by a great poet, Firdausi Tousi, like his other stories in Shahname is a story which can be analyzed by archetyoal approach. According to this approach, this story can be considered as the individuation of here of this story, Bijan, who voluntarily enters into the individuation and psychological growth by being called. In his perfection cycle which is started and in Iran, by the trickery of evil wise old (gorgin, Bijan meets his Anima of unconscious. Bijan, who lived in Ashkanian era as some researchers believe, is one of the prime characters in Shahnameh. From mythical point of view, Bijan story, which is known as one of ancient myths, is the indicator of feminine society in Iran. Bijan story, like Bahram Chobin, Rustam and Sohrab, Ardeshir Babakan, and Rustam and Esfandiar, is an independent story added to Shahnameh. The comparison of Bijan story with other stories of Shahnameh represents this issue that Ferdowsi composed Bijan story in his youth and just after Daghighi’s death. Because Bijan story, like most other stories of Shahnameh and other myths, has a quite symbolic structure and motifs, Jung archetypal point of view is helpful to discover a lot of mysteries. In the present article, Bijan story is analyzed from Jung’s archetypal point of view. According to this theory, there are a lot of symbols, motifs and archetypes in this story. There is a united structure in every story formed base on its plot thus, to discover the structure of a symbolic story is an important act.   The symbolic motif of Bijan story is reaching the perfection and the story structure is completely commensurate with this motif the move is started from Iran, which is the indicator of Bijan story’s consciousness, then the hero after getting individual experience in land of unconscious, Turan, comes back to Iran. Bijan voluntary goes on a dangerous and symbolic way as the hero. Actually he is the portrayal

  2. Hormonal contraception usage is associated with altered memory for an emotional story.

    Substantial evidence now documents sex-related influences on the neurobiology of emotional memory. Robust sex influences exist, for example, on the amygdala's role in emotional memory formation, as well as on retention of central information (gist) and detail for an emotional event. Evidence also suggests that the well-documented effects of stress hormones on memory depend upon sex hormone levels. Since hormonal contraception alters sex hormone levels, and must by extension alter sex/stress hormone interactions in memory, we examined whether the use of hormonal contraception also alters memory for an emotional story. Two groups of healthy female subjects--one naturally cycling, one using hormonal contraception--viewed either a brief, emotionally arousing story, or a closely matched, but more emotionally neutral story. Each subject's eye movements and pupil dilation changes were recorded as they viewed the story. Additionally, saliva samples were taken throughout the experimental session to examine salivary alpha-amylase, a biomarker for norepinephrine. A surprise free recall test one week later measured story memory in all subjects. Naturally cycling women exhibited enhanced memory of story details, but not of central information (gist), in the emotional compared with neutral story conditions. In contrast, women using hormonal contraception exhibited enhanced memory of gist, but not story details, in the emotional compared with neutral story conditions. Analysis of eye movements made while watching the stories indicated that the differences in memory could not be attributed either to a differential attention focus or to the degree of arousal induced by the stories in the two groups. These findings suggest that the use of hormonal contraception alters memory for an emotional event, perhaps by altering sex/stress hormone interactions in memory formation. They also suggest that further investigation of the mnemonic effects of these very widely used treatments is

    Cetacean-focused tourism in Taiwan has grown rapidly since 1997. This development, measured in terms of both number of tour boats and visitors, has resulted in many resource management challenges stemming from the absence of regulation and scientific data. To fill this void in empirical evidence, we used 464 sighting records from 2002 to 2005 to model the impact of cetacean-focused tourism. Cox proportional hazard analysis indicated cetacean avoidance responses to cetacean watching boats were strongly associated with pod size, mother-calf pairs, and cetacean-vessel distances. Mother-calf pairs abandoned their avoidance tactic by 55% compared to noncalf groups when tour boats approached. Second, the hazard ratio of abundance was 0.996, suggesting that the odds of encountering avoidance responses by the cetaceans decreased by 42% for every 100-member increase in the cetacean pod size. Last, distances maintained by boats from the cetaceans was positively related to avoidance responses (i.e., less avoidance behavior with closer interaction). Based on our findings, we have the following recommendations: (a) limit vessels from approaching mothers with calves, (b) limit vessels from approaching small groups of cetaceans, (c) reduced avoidance behavior to boat traffic may be a red flag for potential long-term disturbance, and (d) apply the "precautionary principle" based on the best scientific information available in cetacean-based tourism in Taiwan. These recommendations will help contribute to the sustainable development of cetacean-focused tourism in Taiwan.

    The Surface Water & Ocean Topography (SWOT) mission brings together two communities focused on a better understanding of the world's oceans and its terrestrial surface waters. U.S. and French oceanographers and hydrologists and international partners have joined forces to develop this new space mission. At NASA JPL's PO.DAAC, the team is currently engaged in the gathering of SWOT User Stores (access patterns, metadata requirements, primary and value added product requirements, data access protocols, etc.) to better inform the adaptive planning of what will be known as the next generation PO.DAAC Information Architecture (IA). The IA effort acknowledges that missions such as SWOT (and NISAR) have few or no precedent in terms of data volume, hot and cold storage, archival, analysis, existing system engineering complexities, etc. and that the only way we can better understand the projected impacts of such requirements is to interface directly with the User Community. Additionally, it also acknowledges that collective learning has taken place to understand certain limitations in the existing data models (DM) underlying the existing PO.DAAC Data Management and Archival System. This work documents an evolutionary, use case based, standards driven approach to adapting the legacy DM and accompanying knowledge representation infrastructure at NASA JPL's PO.DAAC to address forthcoming DAAC mission requirements presented by missions such as SWOT. Some of the topics covered in this evolution include, but are not limited to: How we are leveraging lessons learned from the development of existing DM (such as that generated for SMAP) in an attempt to map them to SWOT. What is the governance model for the SWOT IA? What are the `governing' entities? What is the hierarchy of the `governed entities'? How are elements grouped? How is the design-working group formed? How is model independence maintained and what choices/requirements do we have for the implementation language? The use of

    To investigate whether high-intensity focused ultrasound (HIFU) combined with microbubbles enhances the therapeutic effects of chemotherapy. A pancreatic cancer xenograft model was established using BALB/c nude mice and luciferase-expressing human pancreatic cancer cells. Mice were randomly assigned to five groups according to treatment: control (n = 10), gemcitabine alone (GEM; n = 12), HIFU with microbubbles (HIFU + MB, n = 11), combined HIFU and gemcitabine (HIGEM; n = 12), and HIGEM + MB (n = 13). After three weekly treatments, apoptosis rates were evaluated using the terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling assay in two mice per group. Tumor volume and bioluminescence were monitored using high-resolution 3D ultrasound imaging and in vivo bioluminescence imaging for eight weeks in the remaining mice. The HIGEM + MB group showed significantly higher apoptosis rates than the other groups (p < 0.05) and exhibited the slowest tumor growth. From week 5, the tumor-volume-ratio relative to the baseline tumor volume was significantly lower in the HIGEM + MB group than in the control, GEM, and HIFU + MB groups (p < 0.05). Despite visible distinction, the HIGEM and HIGEM + MB groups showed no significant differences. High-intensity focused ultrasound combined with microbubbles enhances the therapeutic effects of gemcitabine chemotherapy in a pancreatic cancer xenograft model.

    New focal destruction technologies such as high-intensity focused ultrasound (HIFU) may improve the prognosis of pancreatic ductal adenocarcinoma. Our objectives were to demonstrate the safety and efficacy of intraoperative pancreatic HIFU ablation in a porcine model. In a porcine model (N = 12), a single HIFU ablation was performed in either the body or tail of the pancreas, distant to superior mesenteric vessels. All animals were sacrificed on the eighth day. The primary objective was to obtain an HIFU ablation measuring at least 1 cm without premature death. In total, 12 HIFU ablations were carried out. These ablations were performed within 160 seconds and on average measured 20 (15-27) × 16 (8-26) mm. The primary objective was fulfilled in all but 1 pig. There were no premature deaths or severe complications. High-intensity focused ultrasound treatment was associated with a transitory increase in amylase and lipase levels, and pseudocysts were observed in half of the pigs without being clinically apparent. All ablations were well delimited at both gross and histological examinations. Intraoperative thermal destruction of porcine pancreas with HIFU is feasible. Reproducibility and safety have to be confirmed when applied close to mesenteric vessels and in long-term preclinical studies.

    News stories reporting race-specific health information commonly emphasize disparities between racial groups. But recent research suggests this focus on disparities has unintended effects on African American audiences, generating negative emotions and less interest in preventive behaviors (Nicholson RA, Kreuter MW, Lapka C et al. Unintended effects of emphasizing disparities in cancer communication to African-Americans. Cancer Epidemiol Biomarkers Prev 2008; 17: 2946–52). They found that black adults are more interested in cancer screening after reading about the progress African Americans have made in fighting cancer than after reading stories emphasizing disparities between blacks and whites. This study builds on past findings by (i) examining how health journalists judge the newsworthiness of stories that report race-specific health information by emphasizing disparities versus progress and (ii) determining whether these judgments can be changed by informing journalists of audience reactions to disparity versus progress framing. In a double-blind-randomized experiment, 175 health journalists read either a disparity- or progress-framed story on colon cancer, preceded by either an inoculation about audience effects of such framing or an unrelated (i.e. control) information stimuli. Journalists rated the disparity-frame story more favorably than the progress-frame story in every category of news values. However, the inoculation significantly increased positive reactions to the progress-frame story. Informing journalists of audience reactions to race-specific health information could influence how health news stories are framed. PMID:21911844

  19. Focused Ethnography

    2005-09-01

    Full Text Available In this paper I focus on a distinctive kind of sociological ethnography which is particularly, though not exclusively, adopted in applied research. It has been proposed that this branch of ethno­graphy be referred to as focused ethnography. Focused ethnography shall be delineated within the context of other common conceptions of what may be called conventional ethnography. However, rather than being opposed to it, focused ethno­graphy is rather complementary to conventional ethnography, particularly in fields that are charac­teristic of socially and functionally differentiated contemporary society. The paper outlines the back­ground as well as the major methodological features of focused ethnography, such as short-term field visits, data intensity and time intensity, so as to provide a background for future studies in this area.

    The book is a collection of short stories, small anecdotes in the life of some historical characters. More concretely, it focuses on the oddities and singularities of some well-known historical figures, not only in science, but also in arts, politics and social sciences. … the book shows the fascination for ancient history, the treasures hidden in original sources and the importance of exploring unusual connections.-Javier Martinez, The European Mathematical Society, January 2013… a rambling, illuminating and thoroughly enjoyable bio/autobiographical and historical sketch, setting Pingree's immense erudition in its professional and intellectual context. Besides a string of amusing and intriguing anecdotes plentifully sprinkled with photos and sketches, this small volume supplies a valuable reminder of how complex, surprising and just plain strange the history of the exact sciences can be.-Kim Plofker, MAA Reviews, October 2012.

    2015-11-01

    Research about victimization among sexual minority youth has focused on documenting the prevalence and consequences of such experiences. Lacking in the literature is an in-depth exploration of the social context of both risk and resilience in the face of violence. This is especially true for transgender youth who are largely absent from the dominant discourse. This case story provides an example of how one transgender youth interpreted and adaptively responded to the discrimination and prejudice she encountered. Katie's story illustrates the process of resilience. Despite the adversity she has faced, she shares stories of pride and strength in a culture that considers her as "other." © The Author(s) 2014.

    2007-01-01

    Human emotional behavior, personality, and body language are the essential elements in the recognition of a believable synthetic story character. This paper presents an approach using story scripts and action descriptions in a form similar to the content description of storyboards to predict specific personality and emotional states. By adopting the Abridged Big Five Circumplex (AB5C) Model of personality from the study of psychology as a basis for a computational model, we construct a hierarchical fuzzy rule-based system to facilitate the personality and emotion control of the body language of a dynamic story character. The story character can consistently perform specific postures and gestures based on his/her personality type. Story designers can devise a story context in the form of our story interface which predictably motivates personality and emotion values to drive the appropriate movements of the story characters. Our system takes advantage of relevant knowledge described by psychologists and researchers of storytelling, nonverbal communication, and human movement. Our ultimate goal is to facilitate the high-level control of a synthetic character.

    Family-integrated care (FICare) is an innovative model of care developed at Mount Sinai Hospital, Canada, to better integrate parents into the team caring for their infant in the neonatal intensive care unit (NICU). The effects of FICare on neonatal outcomes and parental anxiety were assessed in an international multicenter randomized trial. As an Australian regional level 3 NICU that was randomized to the intervention group, we aimed to explore parent and staff perceptions of the FICare program in our dual occupancy NICU. This qualitative study took place in a level 3 NICU with 5 parent participants and 8 staff participants, using a post implementation review design. Parents and staff perceptions of FICare were explored through focus group methodology. Thematic content analysis was done on focus group transcripts. Parents and staff perceived the FICare program to have had a positive impact on parental confidence and role attainment and thought that FICare improved parent-to-parent and parent-to-staff communication. Staff reported that nurses working with families in the program performed less hands-on care and spent more time educating and supporting parents. FICare may change current NICU practice through integrating and accepting parents as active members of the infant's care team. In addition, nurse's roles may transition from bedside carer to care coordinator, educating and supporting parents during their journey through the NICU. Further research is needed to assess the long-term impact of FICare on neonates, parents, and staff.

  5. A semi-analytical model of a time reversal cavity for high-amplitude focused ultrasound applications

    Robin, J.; Tanter, M.; Pernot, M.

    2017-09-01

    Time reversal cavities (TRC) have been proposed as an efficient approach for 3D ultrasound therapy. They allow the precise spatio-temporal focusing of high-power ultrasound pulses within a large region of interest with a low number of transducers. Leaky TRCs are usually built by placing a multiple scattering medium, such as a random rod forest, in a reverberating cavity, and the final peak pressure gain of the device only depends on the temporal length of its impulse response. Such multiple scattering in a reverberating cavity is a complex phenomenon, and optimisation of the device’s gain is usually a cumbersome process, mostly empirical, and requiring numerical simulations with extremely long computation times. In this paper, we present a semi-analytical model for the fast optimisation of a TRC. This model decouples ultrasound propagation in an empty cavity and multiple scattering in a multiple scattering medium. It was validated numerically and experimentally using a 2D-TRC and numerically using a 3D-TRC. Finally, the model was used to determine rapidly the optimal parameters of the 3D-TRC which had been confirmed by numerical simulations.

  6. Identification of a Typical CSTR Using Optimal Focused Time Lagged Recurrent Neural Network Model with Gamma Memory Filter

    Directory of Open Access Journals (Sweden)

    S. N. Naikwad

    2009-01-01

    Full Text Available A focused time lagged recurrent neural network (FTLR NN with gamma memory filter is designed to learn the subtle complex dynamics of a typical CSTR process. Continuous stirred tank reactor exhibits complex nonlinear operations where reaction is exothermic. It is noticed from literature review that process control of CSTR using neuro-fuzzy systems was attempted by many, but optimal neural network model for identification of CSTR process is not yet available. As CSTR process includes temporal relationship in the input-output mappings, time lagged recurrent neural network is particularly used for identification purpose. The standard back propagation algorithm with momentum term has been proposed in this model. The various parameters like number of processing elements, number of hidden layers, training and testing percentage, learning rule and transfer function in hidden and output layer are investigated on the basis of performance measures like MSE, NMSE, and correlation coefficient on testing data set. Finally effects of different norms are tested along with variation in gamma memory filter. It is demonstrated that dynamic NN model has a remarkable system identification capability for the problems considered in this paper. Thus FTLR NN with gamma memory filter can be used to learn underlying highly nonlinear dynamics of the system, which is a major contribution of this paper.

    Current practice before a trans-cranial MR guided Focused ultrasound procedure is shaving the patient head on treatment day. Here we present an initial attempt to evaluate the feasibility of trans-cranial FUS, in an unshaved, ex-vivo cadaver skull. We have sonicated using 220kHz and 710kHz head transducers, a cadaver skull filled with tissue mimicking phantom and covered with a wig made of human hair to evaluate feasibility of acoustic energy transfer in a full size model. Heating at focal point was measured using MR proton resonance shift thermometry. Results showed negligible effect of hair in 220kHz, and an 18% drop in temperature elevation when using 710kHz.

    2002-01-01

    The initiator of the NEA TDB project was Anthony Muller. He came from Sandia and was employed at the NEA Division of Radiation Protection and Radioactive Waste Management from 1983 to 1986. He was aware that the radioactive waste management community needed a high-quality thermodynamic database that is focused on the particular needs of this community. At that time, some critically reviewed and widely used databases did exist: The Critical Stability Constants by Smith and Martell (1974-1977), the NBS Tables of Chemical Thermodynamic Properties (1982) and the IAEA project on Chemical Thermodynamics of the Actinides (10 volumes appeared between 1976 and 1992, four volumes were not published, among which the volume on the actinide oxides). However, none of them presents sufficiently comprehensive data sets for the needs of radioactive waste management. Anthony Muller was very talented in convincing people. He thus succeeded to persuade the Radioactive Waste Management Committee of the NEA of the need to start such an international effort. He defined ten key elements (U, Np, Pu, Am, Tc, Cs, Sr, Ra, 1, Pb) and set up expert teams for each element. However, he greatly underestimated the effort needed for such a critical review, and he announced a timetable that promised the review reports of all ten elements within a total duration of two to three years. This unrealistic estimate put us and the TDB project into serious trouble in the late 1980's. (author)

    Full Text Available Goldmann's genetic structuralism approach is one of the literary critique approaches and believes that the literary text are derived from the ideology governing the classes of society, and focuses on study of stories and their structures to know the social structures. A review of the changes made in the themes and subjects of the works of the Iranian story writers that most of them are from the middle class of society, indicates the growth of awareness and understanding of Iranian women about their identity and individuality and the achievement of conditions beyond what they are. Although in popular stories, most Iranian female storytellers are still interested in the reproduction of traditional gender stereotypes, but female storywriters in the field of transcendental literature have entered the changes made in their cognitive realm to the actions of characters of their stories. This reveals that they seek to understand their own self and place in the world around them. Love and loneliness resulted by the confrontation between men and women are a common theme in these works that have been narrated on the various issues arising from the family and social relationships of women.

    2012-08-01

    Full Text Available The need for outsourcing IT services has shown a significant growth over the past few years. This article presents a proposal for a measurement model for Software Tests with a focus on the management of these outsourced services by governmental organizations. The following specific goals were defined: to identify and analyze the test process; to identify and analyze the existing standards that govern the hiring of IT services and to propose a Measurement Model for outsourced services of this type. As to the analysis of the data collected (documentary research and semi-structured interviews, content analysis was adopted, and in order to prepare the metrics, the GQM – Goal, Questions, Metrics – approach was used. The result was confirmed by semi-structured interviews. Here is what the research identifies as possible: to establish objective and measurable criteria for a measurement size as the input to evaluate the efforts and deadlines involved; to follow up the test sub-processes and to evaluate the service quality. Therefore, the management of this type of service hiring can be done more efficiently.

  19. Modeling localized delivery of Doxorubicin to the brain following focused ultrasound enhanced blood-brain barrier permeability

    2014-01-01

    Doxorubicin (Dox) is a well-established chemotherapeutic agent, however it has limited efficacy in treating brain malignancies due to the presence of the blood-brain barrier (BBB). Recent preclinical studies have demonstrated that focused ultrasound induced BBB disruption (BBBD) enables efficient delivery of Dox to the brain. For future treatment planning of BBBD-based drug delivery, it is crucial to establish a mathematical framework to predict the effect of transient BBB permeability enhancement on the spatiotemporal distribution of Dox at the targeted area. The constructed model considers Dox concentrations within three compartments (plasma, extracellular, intracellular) that are governed by various transport processes (e.g. diffusion in interstitial space, exchange across vessel wall, clearance by cerebral spinal fluid, uptake by brain cells). By examining several clinical treatment aspects (e.g. sonication scheme, permeability enhancement, injection mode), our simulation results support the experimental findings of optimal interval delay between two consecutive sonications and therapeutically-sufficient intracellular concentration with respect to transfer constant K trans range of 0.01–0.03 min −1 . Finally, the model suggests that infusion over a short duration (20–60 min) should be employed along with single-sonication or multiple-sonication at 10 min interval to ensure maximum delivery to the intracellular compartment while attaining minimal cardiotoxicity via suppressing peak plasma concentration.

    1996-01-01

    Social learning theory predicts that reading non-erotic stories involving condom use will be as effective as reading erotic stories with condom use in producing positive attitudes toward condoms. Werner's orthogenetic principle, however, predicts that reading erotic condom stories will be most effective because of the link created between sexual arousal and cognitive information about condoms. 168 male and 149 female undergraduates enrolled in Introductory Psychology at a small, private, southern university participated in a study to test the validity of these two theories. The students read one of the following types of stories: erotic with condom placement described, erotic without condom use, or non-erotic with a model for discussing condoms. The men and women who read the non-erotic stories were most positive about condoms and reported the strongest intentions to use condoms in the future. These findings suggest that erotica is not necessary to produce positive attitudes toward condoms.

    This qualitative study explored the experiences of 26 parents who were involved in surrogate parenting arrangements in a California-based surrogacy program. Participants were mostly white (n = 23). married (n = 25), females (n = 24), with high levels of education and income. The mean age at the time of the first child's birth was 39 yr. (SD = 5.06). The majority of parents reported having one (n = 10) or two (n = 8) children. All subjects reported infertility as their reason to explore surrogacy as a method of building a family. 18 participants chose in vitro fertilization as heir method of conception. Telephone interviews explored their decision-making, ethod of fertilization, their relationship with their surrogate, and the support that they received during the surrogacy process. Results indicate that parents were able to nticipate some potential pitfalls prior to their experience but did not realize the imortance of other potential difficulties. A conceptual model is presented with implications for helping professionals.

  3. Without 'Focus'

    Directory of Open Access Journals (Sweden)

    Aldo Sevi

    2010-12-01

    Full Text Available It is widely accepted that a notion of 'focus', more or less as conceived of in Jackendoff (1972, must be incorporated into our theory of grammar, as a means of accounting for certain observed correlations between prosodic facts and semantic/pragmatic facts. In this paper, we put forth the somewhat radical idea that the time has come to give up this customary view, and eliminate 'focus' from our theory of grammar. We argue that such a move is both economical and fruitful.Research over the years has revealed that the correlations between prosody, 'focus', and the alleged semantic/pragmatic effects of focus are much less clear and systematic than we may have initially hoped. First we argue that this state of affairs detracts significantly from the utility of our notion of 'focus', to the point of calling into question the very motivation for including it in the grammar. Then we look at some of the central data, and show how they might be analyzed without recourse to a notion of 'focus'. We concentrate on (i the effect of pitch accent placement on discourse congruence, and (ii the choice of 'associate' for the so-called 'focus sensitive' adverb only. We argue that our focus-free approach to the data improves empirical coverage, and begins to reveal patterns that have previously been obscured by preconceptions about 'focus'.ReferencesBeaver, D. & Clark, B. 2008.

    2017-01-01

    ABSTRACT Stories are a powerful means to change people’s attitudes and beliefs. The aim of the current work was to shed light on the role of argument strength (argument quality) in narrative persuasion. The present study examined the influence of strong versus weak arguments on attitudes in a low or high narrative context. Moreover, baseline attitudes, interindividual differences in working memory capacity, and recipients’ transportation were examined. Stories with strong arguments were more persuasive than stories with weak arguments. This main effect was qualified by a two-way interaction with baseline attitude, revealing that argument strength had a greater impact on individuals who initially were particularly doubtful toward the story claim. Furthermore, we identified a three-way interaction showing that argument strength mattered most for recipients who were deeply transported into the story world in stories that followed a typical narrative structure. These findings provide an important specification of narrative persuasion theory. PMID:29805322

    To provide opportunities for intergenerational knowledge sharing for healthy lifestyles; to facilitate youth and Elder mentorship; and to increase the self-esteem of youth by celebrating identity, cultural practices and community connection through the creation and sharing of digital stories. A youth research team (8 youth) aged 13-25, youth participants (60 core participants and 170 workshop participants) and Elders (14) from First Nations communities. The project was conducted with participants from several communities on Vancouver Island through on-site workshops and presentations. Youth and Elders were invited to a 3-day digital story workshop consisting of knowledge-sharing sessions by Elders and digital story training by the youth research team. Workshop attendees returned to their communities to develop stories. The group re-convened at the university to create digital stories focused on community connections, family histories and healthy lifestyles. During the following year the research team delivered instructional sessions in communities on the digital story process. The youth involved reported increased pride in community as well as new or enhanced relationships with Elders. The digital stories method facilitated intergenerational interactions and engaged community members in creating a digital representation of healthy lifestyles. The process itself is an intervention, as it affords critical reflection on historical, cultural and spiritual ideas of health and what it means to be healthy in an Aboriginal community. It is a particularly relevant health promotion tool in First Nations communities with strong oral history traditions.

    Story has traditionally been seen as something separate to gameplay—frequently relegated to an afterthought or epiphenomenon. Nevertheless, in the FPS genre there has been something of a renaissance in the notion of the story-driven title. Partially, this is due to advances in technology enabling a greater capacity for distributed storytelling and a better integration of story and gameplay. However, what has been underrecognised is the dynamic, epistemological, and psychological impact of sto...

  9. Patients as story-tellers of healthcare journeys.

    Science.gov (United States)

    Lamprell, Klay; Braithwaite, Jeffrey

    2016-09-01

    There are gaps in our comprehension of patients' subjective experiences as they engage with and transit through the healthcare environments implicated in their treatment trajectories. Patients' stories, unlike patient experience data gathered in questionnaires and surveys, express the deeply personal, narrative nature of the journeys that patients take, creating opportunities for qualitative healthcare research. Yet narrative capabilities and propensities vary with individuals, and are affected by the stresses of illness and treatment. This article extends the growing interest in narrative competence training for both practitioners and patients with the investigation of a story-telling model that could facilitate patients to narrate their experiences of healthcare systems. This model is derived from the literary arts. In fiction and autobiography, the journey arc of the central character is often one in which he or she is compelled to leave the comfort of everyday life and face a series of extraordinary events involving challenge and change which forces the character towards practical, intellectual, psychological and philosophical adjustments that define, by the end of the story, the character's 'new normal'. This pattern is known as the 'hero journey'. Its parallels with patients' experiences of healthcare and the way people narrate their stories of illness have long been recognised. We present here a new idea for applying this model as a narrative structure by which patients may construct their stories about being in and moving through the healthcare system.

    In this paper we build on the notion of computational composites, which hold a material perspective on computational technology. We argue that a focus on the material aspects of the technology could be a fruitful approach to achieve new expressions and to gain a new view on the technology's role...... in design. We study two of the computer's material properties: computed causality and connectability and through developing two computational composites that utilize these properties we begin to explore their potential expressions....

    2011-10-01

    Life story work has been promoted as a tool to enhance the care provided to older people, particularly those with dementia. The benefits for individuals, families and/or friends and for staff include improving understanding of the individual, promoting relationships and assisting in the delivery of person-centred care. However, professionals often experience difficulties using life story work. This article considers a range of life story tools and advice on gathering information about a person. It highlights the importance of leadership and developing positive cultures to ensure that life story work can be effectively sustained.

  13. Re-appraisal and extension of the Gratton-Vargas two-dimensional analytical snowplow model of plasma focus evolution in the context of contemporary research

    International Nuclear Information System (INIS)

    Auluck, S. K. H.

    2013-01-01

    Recent resurgence of interest in applications of dense plasma focus and doubts about the conventional view of dense plasma focus as a purely irrotational compressive flow have re-opened questions concerning device optimization. In this context, this paper re-appraises and extends the analytical snowplow model of plasma focus sheath evolution developed by F. Gratton and J. M. Vargas [Energy Storage, Compression and Switching, edited by V. Nardi, H. Sahlin, and W. H. Bostick (Plenum, New York, 1983), Vol. 2, p. 353)] and shows its relevance to contemporary research. The Gratton-Vargas (GV) model enables construction of a special orthogonal coordinate system in which the plasma flow problem can be simplified and a model of sheath structure can be formulated. The Lawrenceville Plasma Physics (LPP) plasma focus facility, which reports neutron yield better than global scaling law, is shown to be operating closer to an optimum operating point of the GV model as compared with PF-1000

    2011-10-01

    This study explored how forgiveness unfolds in the context of emotion-focused couples therapy (EFT-C) in eight cases of women betrayed by their partners. Forgiveness was defined as a process involving the reduction in negative feelings and the giving out of undeserved compassion. This was measured by changes in the pre- and posttreatment scores on the Enright Forgiveness Inventory, the Unfinished Business Resolution Scale, and a single item directly asking respondents to indicate their degree of forgiveness. A task analysis was performed to rigorously track the steps leading to forgiveness using videotapes of therapy sessions for eight couples. The performance of the four couples who forgave were compared with each other and then contrasted with the performance of another four couples who did not reach forgiveness at the end of therapy. Based on these observations, a model of the process of forgiveness in EFT-C and a process rating system were developed. © 2011 American Association for Marriage and Family Therapy.

    1995-01-01

    This exploratory study examined the use of two components (small and large groups) of a community-based intervention, the Focused Support Group (FSG) model, to alleviate employment-related stressors in Black women. Participants were assigned to small groups based on occupational status. Groups met for five weekly 3-hr sessions in didactic or small- and large-group formats. Two evaluations following the didactic session and the small and large group sessions elicited information on satisfaction with each of the formats, self-reported change in stress, awareness of interpersonal and sociopolitical issues affecting Black women in the labor force, assessing support networks, and usefulness of specific discussion topics to stress reduction. Results indicated the usefulness of the small- and large-group formats in reduction of self-reported stress and increases in personal and professional sources of support. Discussions on race and sex discrimination in the workplace were effective in overall stress reduction. The study highlights labor force participation as a potential source of stress for Black women, and supports the development of culture- and gender-appropriate community interventions as viable and cost-effective methods for stress reduction.

  16. More than pretty pictures? How illustrations affect parent-child story reading and children's story recall

    Greenhoot, Andrea Follmer; Beyer, Alisa M.; Curtis, Jennifer

    2014-01-01

    Previous research showed that story illustrations fail to enhance young preschoolers' memories when they accompany a pre-recorded story (e.g., Greenhoot and Semb, 2008). In this study we tested whether young children might benefit from illustrations in a more interactive story-reading context. For instance, illustrations might influence parent-child reading interactions, and thus children's story comprehension and recall. Twenty-six 3.5- to 4.5-year-olds and their primary caregivers were randomly assigned to an Illustrated or Non-Illustrated story-reading condition, and parents were instructed to “read or tell the story” as they normally would read with their child. Children recalled the story after a distracter and again after 1 week. Analyses of the story-reading interactions showed that the illustrations prompted more interactive story reading and more parent and child behaviors known to predict improved literacy outcomes. Furthermore, in the first memory interview, children in the Illustrated condition recalled more story events than those in the Non-Illustrated condition. Story reading measures predicted recall, but did not completely account for picture effects. These results suggest that illustrations enhance young preschoolers' story recall in an interactive story reading context, perhaps because the joint attention established in this context supports children's processing of the illustrations.

    The aim of this study was to investigate stories of recovery through the lens of intensive care unit (ICU) survivors. Survival from ICUs is increasing, as are associated physical and psychological complications. Despite the significant impact on survivors, there is inadequate support provision in Australia and world-wide for this population. An interpretive biographical approach of intensive care survivors' experiences of recovery. Data were collected during 2014-2015 from diaries, face to face interviews, memos and field notes. Six participants diarized for 3 months commencing 2 months after hospital discharge. At 5 months, participants were interviewed about the content of their diaries and symbols and signifiers in them to create a shared meaning. Analysis of diaries and interviews were undertaken using two frameworks to identify themes throughout participants' stories and provides a unique portrait of recovery through their individual lens. Participants considered their lives had irreparably changed and yet felt unsupported by a healthcare system that had "saved" them. This view through their lens identified turmoil, which existed between their surface and inner worlds as they struggled to conform to what recovery "should be". The novel biographical methods provided a safe and creative way to reveal survivors' inner thoughts and feelings. Participants' considered creating their stories supported their recovery process and in particular enabled them to reflect on their progress. Findings from this study may lead to increased awareness among health care providers about problems survivors face and improved support services more broadly, based on frameworks appropriate for this population. © 2018 John Wiley & Sons Ltd.

  3. Women’s stories implying aspects of anti-Judaism with Christological depiction in Matthew

    Directory of Open Access Journals (Sweden)

    In-Cheol Shin

    2014-10-01

    Full Text Available This study focuses on the women’s stories that imply aspects of anti-Judaism within Matthew’s depiction of Christology, which is called Matthew’s theology. In fact, Matthew’s community opposed the Jewish system and Jewish leaders and parted from its parent body. Even though Matthew’s community was still similar to the Jewish system, it had significant differences as well. The study discusses these aspects of anti-Judaism that appear in the woman’s stories that include the genealogy of Jesus, the haemorrhaging woman, the Canaanite woman, and the women at the cross and Jesus’ tomb. This study shows proof and examples of anti-Judaism within the stories and thoroughly analyses them. Therefore, it can be confirmed that the women’s stories imply aspects of anti-Judaism with Christological depictions by Matthew’s theological tendency.

    2017-07-01

    Full Text Available The vast amount of published narratives on the last decade in Mexico, linked to an unnerving social climate produced by drug trafficking and corruption, is highly noticeable. In response to these sociopolitical conditions, it seems to me that the stories that don´t approach violence directly should be questioned. Here I pose that oblique writing is a form of resisting the possibility that violence is being nurtured from language. In this article I focus on “Ptosis”, one of the short stories in Pétalos y otras historias incómodas (2008 by Guadalupe Nettel. Appealing to the theoretical approaches of Ariel Dorfman, Amartya Sen, Arjun Appadurai, Walter Benjamin, and Roland Barthes, and others, I aim to reflect on the nature of identities and their survival methods, in the midst of a violence social context.

    Our goal was to develop an interactive DVD to help African American and Caucasian American adults with hypertension learn how to become better communicators during medical interactions. Material was to be presented in several formats, including patients' narratives (stories). To develop the narratives we recruited members of the target audience and elicited stories and story units in focus groups, interviews, and seminars. Story units were ranked-ordered based on conformance with the theory of planned behavior and narrative qualities and then melded into cohesive stories. The stories were recounted by actors on the DVD. 55 adults (84% women; 93% African American) participated in a focus group, interview, or seminar; transcripts yielded 120 story units. The most highly rated units were woven into 11 stories. The six highest rated stories/actor-storytellers were selected for presentation on the DVD. We achieved our goal of developing an easy-to-use, story-driven product that may teach adults how to talk effectively with their doctors about hypertension. The DVD's effectiveness should be tested in a randomized trial. Behavioral interventions aimed at improving patients' ability to communicate during doctor visits may be useful adjuncts in the achievement of BP goals. Copyright (c) 2009 Elsevier Ireland Ltd.

  6. Application of Story-wise Shear Building Identification Method to Actual Ambient Vibration

    Directory of Open Access Journals (Sweden)

    2015-02-01

    Full Text Available A sophisticated and smart story stiffness System Identification (SI method for a shear building model is applied to a full-scale building frame subjected to micro-tremors. The advantageous and novel feature is that not only the modal parameters, such as natural frequencies and damping ratios, but also the physical model parameters, such as story stiffnesses and damping coefficients, can be identified using micro-tremors. While the building responses to earthquake ground motions are necessary in the previous SI method, it is shown in this paper that the micro-tremor measurements in a full-scale 5 story building frame can be used for identification within the same framework. The SI using micro-tremor measurements leads to the enhanced usability of the previously proposed story-wise shear building identification method. The degree of ARX models and cut-off frequencies of band-pass filter are determined to derive reliable results.

    Objective To understand if narratives can be effective tools for diabetes empowerment, from the perspective of African-American participants in a program that improved diabetes self-efficacy and self-management. Methods In-depth interviews and focus groups were conducted with program graduates. Participants were asked to comment on the program's film, storytelling, and role-play, and whether those narratives had contributed to their diabetes behavior change. An iterative process of coding, analyzing, and summarizing transcripts was completed using the framework approach. Results African-American adults (n = 36) with diabetes reported that narratives positively influenced the diabetes behavior change they had experienced by improving their attitudes/beliefs while increasing their knowledge/skills. The social proliferation of narrative – discussing stories, rehearsing their messages with role-play, and building social support through storytelling – was reported as especially influential. Conclusion Utilizing narratives in group settings may facilitate health behavior change, particularly in minority communities with traditions of storytelling. Theoretical models explaining narrative's effect on behavior change should consider the social context of narratives. Practice implications Narratives may be promising tools to promote diabetes empowerment. Interventions using narratives may be more effective if they include group time to discuss and rehearse the stories presented, and if they foster an environment conducive to social support among participants.

    Full Text Available During an earthquake, the behaviour of any structure is affected not only by the superstructure response, but also by the response of the soil beneath. Recent structural failure patterns have indicated the significance of soil-structure interaction (SSI effects. The present study focuses on SSI analysis considering the embedment depth of the foundation of a symmetric six stories reinforced concrete (RCspace bare frame building resting on stiff soil and subjected to seismic loading. The finite element analysis software ANSYS v17.2 is used. Time history (TH analysis has been adopted. The Response in terms of lateral displacements, base shear forces, base moments and variation in natural time periods are calculated from the analysis of the soil foundation structure interaction (SFSI model. Results are compared with that obtained from conventional method assuming rigid support at the base (fixed base of the structure. The results show that the SFSI considering different embedment depths are significant in altering the seismic response of the multi-story building (MSB.

  10. Three Things to Do With Stories: Using Literature in Medical, Health Professions, and Interprofessional Education.

    Science.gov (United States)

    Blackie, Michael; Wear, Delese

    2015-10-01

    It would be unusual to find a current medical school administrator or faculty member who has not heard the phrase "literature and medicine" or who does not know that literature is taught in various forms-short stories, novels, poems, essays-at many points in the curriculum at U.S. medical schools. Yet the phrase is used in slippery if not elusive ways, with no clear referent common to all who use it. This article focuses on three theoretical and pedagogical uses for literature in medical, health professions, and interprofessional education: close reading, ethical or moral inquiry, and drawing illustrations. Summaries of these approaches are provided, followed by demonstrations of how they might work in the classroom by using the story "Blankets," by Native American writer Sherman Alexie.Close reading requires reading slowly and carefully to enrich an initial encounter with a text. Ethical or moral inquiry turns to literary representations to challenge readers' assumptions and prejudices. Literature offers rich, provoking, and unusual depictions of common phenomena, so it can be used to draw illustrations. Although each approach can be used on its own, the authors argue that reading closely makes the other two approaches possible and meaningful because it shares with the diagnostic process many practices critical to skilled interprofessional caregiving: paying attention to details, gathering and reevaluating evidence, weighing competing interpretations. By modeling a close reading of a text, faculty can demonstrate how this skill, which courts rather than resists ambiguity, can assist students in making ethical and compassionate judgments.

    2015-01-01

    Magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) is a promising technique for palliative treatment of bone pain. In this study, the effects of MR-HIFU ablation on bone mechanics and modeling were investigated. A total of 12 healthy rat femurs were ablated using 10 W for 46 ± 4 s per sonication with 4 sonications for each femur. At 7 days after treatments, all animals underwent MR and single photon emission computed tomography/computed tomography (SPECT/CT) imaging. Then, six animals were euthanized. At 1 month following ablations, the remaining six animals were scanned again with MR and SPECT/CT prior to euthanization. Thereafter, both the HIFU-treated and contralateral control bones of three animals from each time interval were processed for histology, whereas the remaining bones were subjected to micro-CT (μCT), three-point bending tests, and micro-finite element (micro-FE) analyses. At 7 days after HIFU ablations, edema formation around the treated bones coupled with bone marrow and cortical bone necrosis was observed on MRI and histological images. SPECT/CT and μCT images revealed presence of bone modeling through an increased uptake of (99m)Tc-MDP and formation of woven bone, respectively. At 31 days after ablations, as illustrated by imaging and histology, healing of the treated bone and the surrounding soft tissue was noted, marked by decreased in amount of tissue damage, formation of scar tissue, and sub-periosteal reaction. The results of three-point bending tests showed no significant differences in elastic stiffness, ultimate load, and yield load between the HIFU-treated and contralateral control bones at 7 days and 1 month after treatments. Similarly, the elastic stiffness and Young's moduli determined by micro-FE analyses at both time intervals were not statistically different. Multimodality imaging and histological data illustrated the presence of HIFU-induced bone damage at the cellular level, which activated the

  12. Focusing horn

    CERN Multimedia

    1980-01-01

    This was the first magnetic horn developed by Simon Van der Meer to collect antiprotons in the AD complex. It was used for the AA (antiproton accumulator). Making an antiproton beam took a lot of time and effort. Firstly, protons were accelerated to an energy of 26 GeV/c (protons at 26GeV/c, antiprotons at 3.6GeV/c) in the PS and ejected onto a metal target. From the spray of emerging particles, a magnetic horn picked out 3.6 GeV antiprotons for injection into the AA through a wide-aperture focusing quadrupole magnet. For a million protons hitting the target, just one antiproton was captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 -, three hundred thousand million - antiprotons. The development of this technology was a key step to the functioning of CERN's Super Proton Synchrotron as a proton - antiproton collider.

  13. Modelisation of transport in fractured media with a smeared fractures modeling approach: special focus on matrix diffusion process.

    Fourno, A.; Grenier, C.; Benabderrahmane, H.

    2003-04-01

    Modeling flow and transport in natural fractured media is a difficult issue due among others to the complexity of the system, the particularities of the geometrical features, the strong parameter value contrasts between the fracture zones (flow zones) and the matrix zones (no flow zones). This lead to the development of dedicated tools like for instance discrete fracture network models (DFN). We follow here another line applicable for classical continuous modeling codes. The fracture network is not meshed here but presence of fractures is taken into account by means of continuous heterogeneous fields (permeability, porosity, head, velocity, concentration ...). This line, followed by different authors, is referred as smeared fracture approach and presents the following advantages: the approach is very versatile because no dedicated spatial discretization effort is required (we use a basic regular mesh, simulations can be done on a rough mesh saving computer time). This makes this kind of approach very promising for taking heterogeneity of properties as well as uncertainties into account within a Monte Carlo framework for instance. Furthermore, the geometry of the matrix blocks where transfers proceed by diffusion is fully taken into account contrary to classical simplified 1D approach for instance. Nevertheless continuous heterogeneous field representation of a fractured medium requires a homogenization process at the scale of the mesh considered. Literature proves that this step of homogenization for transport is still a challenging task. Consequently, the level precision of the results has to be estimated. We precedently proposed a new approach dedicated to Mixed and Hybrid Finite Element approach. This numerical scheme is very interesting for such highly heterogeneous media and in particular guaranties exact conservation of mass flow for each mesh leading to good transport results. We developed a smeared fractures approach to model flow and transport limited to

    Full Text Available In this study, it is investigated that how much story map graphic organizers contribute to foster writing short stories. Eighteen EFL students from foundation year were randomly chosen and provided eight writing courses. First, the writing teacher provided a topic to the students for each course, and asked them to write three short stories about given topics. In the following two lessons, the instructor introduced graphic organizers and taught the elements of short story to the students. Later, they were given another three topics for the following three courses to create short stories using story map graphic organizers created by writing teacher. Then, the researcher selected two of their first and second pieces randomly and developed a scale to assess the students’ first and second products. The results were classified by including story elements.in two tables as percentage.

    Purpose – This paper aims to explore the “Fellowship-Tale” as an alternative tale type for narrating entrepreneur stories. The authors illustrate this by telling the Pilgrim business story. It is common for the deeds of men who founded businesses to be narrated as heroic entrepreneur stories...... – The research indicates that “fellowship-tales” provide a viable and credible alternative to the fairy-tale rendition common in entrepreneur and business stories. Research limitations/implications – An obvious limitation is that one merely swaps one narrative framework for another, albeit it offers dissenting...... voices a real choice. Practical implications – This study has the potential to be far reaching because at a practical level, it allows disengaged entrepreneurs and significant others the freedom to exercise their individual and collective voices within a framework of nested stories.

    Although storybooks are often used as pedagogical tools for conveying moral lessons to children, the ability to spontaneously extract "the moral" of a story develops relatively late. Instead, children tend to represent stories at a concrete level - one that highlights surface features and understates more abstract themes. Here we examine the role of explanation in 5- and 6-year-old children's developing ability to learn the moral of a story. Two experiments demonstrate that, relative to a control condition, prompts to explain aspects of a story facilitate children's ability to override salient surface features, abstract the underlying moral, and generalize that moral to novel contexts. In some cases, generating an explanation is more effective than being explicitly told the moral of the story, as in a more traditional pedagogical exchange. These findings have implications for moral comprehension, the role of explanation in learning, and the development of abstract reasoning in early childhood. Copyright © 2016 Elsevier B.V.

    To investigate caregivers' preference regarding dental stories to prepare children with autism for dental visits. Caregivers of children with autism were allowed use of dental stories available via different media (paper, tablet computer, computer) and image types (comics or drawings, photographs, video). Caregivers completed pre- and postintervention surveys. Fisher's exact tests were used to determine associations between predictive factors and preferences. Forty initial and 16 follow-up surveys were completed. Subjects were primarily male (85%). Mean child age was 6.7 years. Nine (64%) caregivers found the dental story useful for themselves and their child. Two (14%) caregivers found the aid only helpful for themselves. Preferred media type was associated with language understanding (p = .038) and home media preference (p = .002). Practitioners should consider using dental stories to help prepare families and children for dental visits. Individual preferences for dental stories vary; using prior history can aid in selection. © 2016 Special Care Dentistry Association and Wiley Periodicals, Inc.

  12. Laser beam induced nanoscale spot through nonlinear “thick” samples: A multi-layer thin lens self-focusing model

    International Nuclear Information System (INIS)

    Wei, Jingsong; Yan, Hui

    2014-01-01

    Self-focusing is a well-researched phenomenon. Nanoscale spots can be achieved through self-focusing, which is an alternative method for achieving high-density data storage, high-resolution light imaging, and maskless nanolithography. Several research groups have observed that self-focusing spots can be reduced to nanoscale levels via incident laser power manipulation. Self-focusing spots can be analyzed by solving the nonlinear Schrödinger equation and the finite difference time domain method. However, both procedures are complex and time-consuming. In the present work, a multi-layer thin-lens self-focusing model that considers diffraction effects and changes of refractive index along the radial and film thickness directions is proposed to analyze the self-focusing behavior and traveling process of light beams intuitively. The self-focusing behaviors of As 2 S 3 are simulated, and results show that a nanoscale self-focusing spot with a radius of about 0.12 μm can be formed at the bottom of nonlinear sample when the incident laser power exceeds 4.25 mW. Our findings are basically consistent with experimental reports and provide a good method for analyzing and understanding the self-focusing process. An appropriate application schematic design is also provided

    2016-01-01

    This book uses the spiral shape as a key to a multitude of strange and seemingly disparate stories about art, nature, science, mathematics, and the human endeavour. In a way, the book is itself organized as a spiral, with almost disconnected chapters circling around and closing in on the common theme. A particular strength of the book is its extremely cross-disciplinary nature - everything is fun, and everything is connected! At the same time, the author puts great emphasis on mathematical and scientific correctness, in contrast, perhaps, with some earlier books on spirals. Subjects include the mathematical properties of spirals, sea shells, sun flowers, Greek architecture, air ships, the history of mathematics, spiral galaxies, the anatomy of the human hand, the art of prehistoric Europe, Alfred Hitchcock, and spider webs, to name a few.

  18. Jenny's story: reinventing oneself through occupation and narrative configuration.

    Science.gov (United States)

    Price-Lackey, P; Cashman, J

    1996-04-01

    Two life history interviews were conducted to discover how one women, Jenny, experienced a traumatic head injury, rehabilitation, and recovery. Narrative analysis of the transcribed interviews revealed a rich story of how Jenny had fashioned her identity and character through childhood occupations, including studying classical literature and music, and of how she drew upon resources developed in childhood to engineer her recovery. It also illustrated how Jenny used a recursive process of narrative construction and engagement in self-devised graduated occupations, including studying, playing music, writing, computer graphics, and theater production, to create a new identity and develop capacities to process complex information and exercise creativity. Jenny's story illustrates the usefulness of gaining a perspective on patients as occupational beings through the gathering of life histories focused on occupation, the importance of collaborative patient-therapist goal setting, and the necessity for considering both the doing (practic) and the meaning (narrative) aspects of occupation. Her story supports many scholars' arguments that the therapeutic relationship, and thus occupational therapy practice, may be enhanced through the use of life history interviewing in occupational therapy evaluation and treatment.

  19. A storied-identity analysis approach to teacher candidates learning to teach in an urban setting

    Ibourk, Amal

    While many studies have investigated the relationship between teachers' identity work and their developing practices, few of these identity focused studies have honed in on teacher candidates' learning to teach in an urban setting. Drawing upon narrative inquiry methodology and a "storied identity" analytic framework, I examined how the storied identities of science learning and becoming a science teacher shape teacher candidates' developing practice. In particular, I examined the stories of three interns, Becky, David, and Ashley, and I tell about their own experiences as science learners, their transitions to science teachers, and the implications this has for the identity work they did as they navigated the challenges of learning to teach in high-needs schools. Initially, each of the interns highlighted a feeling of being an outsider, and having a difficult time becoming a fully valued member of their classroom community in their storied identities of becoming a science teacher in the beginning of their internship year. While the interns named specific challenges, such as limited lab materials and different math abilities, I present how they adapted their lesson plans to address these challenges while drawing from their storied identities of science learning. My study reveals that the storied identities of becoming a science teacher informed how they framed their initial experiences teaching in an urban context. In addition, my findings reveal that the more their storied identities of science learning and becoming a science teacher overlapped, the more they leveraged their storied identity of science learning in order to implement teaching strategies that helped them make sense of the challenges that surfaced in their classroom contexts. Both Becky and Ashley leveraged their storied identities of science learning more than David did in their lesson planning and learning to teach. David's initial storied identity of becoming a science teacher revealed how he

    Full Text Available Storytelling and vernacular religion are complementary on multiple levels in the example of Lipsi (southeast Aegean, Greece, where the use of common symbols proves to be more durable than practices, even when the framework of official religion has changed. It is on this narrative web, which unfolds as oral tradition, as ritual practices or as landscape, that community members portray their routes over space and time.. This flow of stories told by all members of the community at every kind of gathering makes a collective identity trait through which the islanders communicate their worldviews, their perception of local history and shape their present lives as well. In my ethnography of Lipsi, storytelling emerges as an “art”, in terms of aesthetic expression through performance. However, at the ‘very moment’ of this fieldwork experience, the natural and supernatural worlds are perceived as an indivisible whole whose parts are in constant communication, either through miracles, hierophanies and visions or through an abundance of wishes and invocations that people utter all the time in their everyday routine. In this paper I also report my own intersubjective amalgamation as a she-ethnographer within the fieldwork I conducted in the small Aegean island. The paper focuses on the storytelling practices of the community, presenting fieldwork data registered during 2005-2011, and 2014.

    2015-01-01

    Sharing stories is an important social activity in everyday life. This study used fine-grained content analysis to investigate the accuracy of recall of two central story elements: the gist and detail of socially-relevant stories. Younger (M age = 28.06) and older (M age = 75.03) American men and women (N = 63) recalled fictional stories that were coded for (i) accuracy of overall gist and specific gist categories and (ii) accuracy of overall detail and specific detail categories. Findings showed no age group differences in accuracy of overall gist or detail, but differences emerged for specific categories. Older adults more accurately recalled the gist of when the event occurred whereas younger adults more accurately recalled the gist of why the event occurred. These differences were related to episodic memory ability and education. For accuracy in recalling details, there were some age differences, but gender differences were more robust. Overall, women remembered details of these social stories more accurately than men, particularly time and perceptual details. Women were also more likely to accurately remember the gist of when the event occurred. The discussion focuses on how accurate recall of socially-relevant stories is not clearly age-dependent but is related to person characteristics such as gender and episodic memory ability/education.

    Williams, Susan Lecky

    Studies have shown both the risk of post traumatic stress following intensive care unit treatment, and the helpfulness of telling trauma stories for psychological recovery. This article is based on recent doctoral research exploring the impact of unexpected life threatening events after admission to hospital. The original research used a qualitative design blending discourse, narrative and phenomenological approaches, guided by sensitivity to participants' evolving work of pulling stories together. Patients chosen from ICU discharge summaries showing a critical life threatening event after admission gave unstructured interviews soon after discharge from hospital and a year later. This article focuses on one particular finding, showing that critical illness can make it difficult for patients to construct personal stories of their experience. Limited evidence suggested overcoming those difficulties meant they had an improved sense of wellbeing a year after discharge. Stories are an essential way in which humans make sense of their experience, which is crucial both for responding appropriately and for personal wellbeing following traumatic life events. Therefore, difficulties in "storying" significant experience can have a negative impact on wellbeing. Some patients need help piecing together stories of their critical illness experience.

    1993-04-01

    Finally, what is it about RN students' experiences in the transition process in nursing education that makes their stories need to be told? Actually this question is asked from both the side of the RN students who are the learners and need to tell the stories, and the side of the educator/advisor who needs to have the stories told. In short, the answer to both is that these stories reveal very graphically and meaningfully what is happening in the learning and professional development processes and, simultaneously, they facilitate the progression of those processes. The RN students seem to have an innate sense about what telling their stories will do for them in relation to their learning and professional development processes. They require very little encouragement to prompt their story telling. For the educators/advisors, no other strategy is as adaptable and achieves as much in relation to facilitating the learning and development processes. For both parties, the graphic revelations in stories paint a picture of how past, present, and future blend together to form a meaningful, coherent view of a position in the world. According to Antonovsky's (1979) work on stress and coping, such a view is necessary if stress is to be resisted and health maintained.(ABSTRACT TRUNCATED AT 400 WORDS)

  6. An early story of Kho Ping Hoo

    Full Text Available Kho Ping Hoo (1926–1994 is the most well-known of all Indonesian writers of popular silat stories, largely set in China, which describe the adventures and romances of legendary heroes famed for their skill in martial arts. It is less well-known that he began his career writing critical stories about socio-economic conditions in the late 50s and early 60s. This paper discusses one of these stories. It places the story in the context of political developments of the time, in particular as they affected the Chinese Indonesian community. The paper argues that this story and one or two others like it come at the end of a tradition of Sino-Indonesian literature which had flourished from the end of the nineteenth century until the mid-1950s. After 1960, Chinese-Indonesian writers cease writing realist fiction of any kind and write either silat stories or romantic stories set in middle class urban environments.

  9. What is not, but might be: The disnarrated in parents' stories of their child's cancer treatment.

    Science.gov (United States)

    Vindrola-Padros, Cecilia; Brage, Eugenia

    2017-11-01

    The study of illness narratives is based on the premise that stories are told for a reason and storytellers make narrative decisions on what to include and leave out of a story, the style of narration, the place where the story is told and the audience. Through this narrative work, they situate themselves in particular ways and make sense of the illness and the world around them. In this article, we explore the disnarrated, a style of narration that features events that do not happen, but are nonetheless referred to in the story. The aim of the article is to illustrate the additional layers of meaning that can be uncovered from illness stories when attention is paid to what did not happen, but, yet, is still part of the story. We draw from a qualitative study carried out with 17 parents whose children were diagnosed with cancer and were receiving medical care in Argentina. We carried out narrative interviews with the parents and participant-observation in hospital areas and the hotels where they resided during treatment. The analysis of the interview transcripts was carried out using a holistic understanding of the narratives and focusing on the identification of themes that appeared disnarrated. The fieldnotes from the observations were used to contextualize the narrative analysis. The disnarrated, in its many manifestations, produced a layer of analysis of parents' stories of treatment patterned by parents' desires, hopes and fears. The disnarrated was used by parents to discuss alternative care trajectories and express fears regarding what the future would bring for the child and family. The disnarrated is a useful analytical tool for examining illness stories as it points to storytellers' views of what is acceptable or desirable in their world and their hopes and preferences for alternative realities.

We see instrumental ethnography as a particular form of ethnography that recognizes ethnographic stories as agential through their capacity to work...... partners in a development aid project; it tells about the seemingly magic actions of a database used for monitoring. We use the note for discussing why we think it is important, in a situation where ethnographic stories are bought and sold as products, to name some of the ontological commitments that go...... into the crafting of these stories....

    Directory of Open Access Journals (Sweden)

    Feras Khalil

    2011-01-01

    Full Text Available The concept of physiologically based pharmacokinetic (PBPK modeling was introduced years ago, but it has not been practiced significantly. However, interest in and implementation of this modeling technique have grown, as evidenced by the increased number of publications in this field. This paper demonstrates briefly the methodology, applications, and limitations of PBPK modeling with special attention given to discuss the use of PBPK models in pediatric drug development and some examples described in detail. Although PBPK models do have some limitations, the potential benefit from PBPK modeling technique is huge. PBPK models can be applied to investigate drug pharmacokinetics under different physiological and pathological conditions or in different age groups, to support decision-making during drug discovery, to provide, perhaps most important, data that can save time and resources, especially in early drug development phases and in pediatric clinical trials, and potentially to help clinical trials become more “confirmatory” rather than “exploratory”.

    As the U.S. Department of Energy's (DOE's) Solar Energy Technologies Program prepares to initiate a new cost-shared research and development (R&D) effort on photovoltaic (PV) manufacturing, it is useful to review the experience to date with consortia focused on PV R&D, manufacturing, and testing. Information was gathered for this report by conducting interviews and accessing Web sites of 14 U.S. consortia and four European consortia, each with either a primary focus on or an emerging interest in PV technology R&D, manufacturing, or testing. Additional input was collected from several workshops held by the DOE and National Academy of Sciences (NAS) in 2009, which examined the practical steps -- including public-private partnerships and policy support -- necessary to enhance the United States' capacity to competitively manufacture photovoltaics. This report categorizes the 18 consortia into three groups: university-led consortia, industry-led consortia, and manufacturing and testing facilities consortia. The first section summarizes the organizations within the different categories, with a particular focus on the key benefits and challenges for each grouping. The second section provides a more detailed overview of each consortium, including the origins, goals, organization, membership, funding sources, and key contacts. This survey is a useful resource for stakeholders interested in PV manufacturing R&D, but should not imply endorsement of any of these groups.
