2010-01-01

Two experiments were conducted in order to find out whether textual features of narratives differentially affect credibility judgments made by judges having different levels of absorption (a disposition associated with rich visual imagination). Participants in both experiments were exposed to a textual narrative and requested to judge whether the narrator actually experienced the event he described in his story. In Experiment 1, the narrative varied in terms of language (literal, figurative) and plausibility (ordinary, anomalous). In Experiment 2, the narrative varied in terms of language only. The participants' perceptions of the plausibility of the story described and the extent to which they were absorbed in reading were measured. The data from both experiments together suggest that the groups applied entirely different criteria in credibility judgments. For high-absorption individuals, their credibility judgment depends on the degree to which the text can be assimilated into their own vivid imagination, whereas for low-absorption individuals it depends mainly on plausibility. That is, high-absorption individuals applied an experiential mental set while judging the credibility of the narrator, whereas low-absorption individuals applied an instrumental mental set. Possible cognitive mechanisms and implications for credibility judgments are discussed.

Encoding Theory of Mind in Character Design for Pedagogical Interactive Narrative

Mei Si

2014-01-01

Full Text Available Computer aided interactive narrative allows people to participate actively in a dynamically unfolding story, by playing a character or by exerting directorial control. Because of its potential for providing interesting stories as well as allowing user interaction, interactive narrative has been recognized as a promising tool for providing both education and entertainment. This paper discusses the challenges in creating interactive narratives for pedagogical applications and how the challenges can be addressed by using agent-based technologies. We argue that a rich model of characters and in particular a Theory of Mind capacity are needed. The character architect in the Thespian framework for interactive narrative is presented as an example of how decision-theoretic agents can be used for encoding Theory of Mind and for creating pedagogical interactive narratives.

The Limits of Narrative: Provocations for the Medical Humanities

Science.gov (United States)

Woods, Angela

2014-01-01

This paper aims to (re)ignite debate about the role of narrative in the medical humanities. It begins with a critical review of the ways in which narrative has been mobilised by humanities and social science scholars to understand the experience of health and illness. I highlight seven dangers or blind spots in the dominant medical humanities approach to narrative, including the frequently unexamined assumption that all human beings are “naturally narrative.” I then explore this assumption further through an analysis of philosopher Galen Strawson’s influential article “Against Narrativity.” Strawson rejects the descriptive claim that “human beings typically see or live or experience their lives as a narrative” and the normative claim that “a richly Narrative outlook is essential to a well-lived life, to true or full personhood.” His work has been taken up across a range of disciplines but its implications in the context of health and illness have not yet been sufficiently discussed. This article argues that “Against Narrativity” can and should stimulate robust debate within the medical humanities regarding the limits of narrative, and concludes by discussing a range of possibilities for venturing “beyond narrative.” PMID:22038696

Understanding the Narratives Explaining the Ukrainian Crisis: Identity Divisions and Complex Diversity in Ukraine

Directory of Open Access Journals (Sweden)

Smoor Lodewijk

2017-09-01

Full Text Available The central argument of this paper is that radical and opposing interpretations of the Ukrainian conflict in politics and media should be studied as offspring of broader narratives. These narratives can be better understood by examining the national identity of Ukraine. Since Ukrainian national identity shows a high degree of diversity, it offers a rich source of arguments for any party wanting to give an interpretation of the present Ukrainian crisis. Narratives explaining the crisis often ignore this complex diversity or deliberately use elements from it to construct the ‘desired’ narrative.

Linguistic spatial classifications of event domains in narratives of crime

Directory of Open Access Journals (Sweden)

Blake Stephen Howald

2010-07-01

Full Text Available Structurally, formal definitions of the linguistic narrative minimally require two temporally linked past-time events. The role of space in this definition, based on spatial language indicating where events occur, is considered optional and non-structural. However, based on narratives with a high frequency of spatial language, recent research has questioned this perspective, suggesting that space is more critical than may be readily apparent. Through an analysis of spatially rich serial criminal narratives, it will be demonstrated that spatial information qualitatively varies relative to narrative events. In particular, statistical classifiers in a supervised machine learning task achieve a 90% accuracy in predicting Pre-Crime, Crime, and Post-Crime events based on spatial (and temporal information. Overall, these results suggest a deeper spatial organization of discourse, which not only provides practical event resolution possibilities, but also challenges traditional formal linguistic definitions of narrative.

Computer Texture Mapping for Laser Texturing of Injection Mold

Directory of Open Access Journals (Sweden)

Yongquan Zhou

2014-04-01

Full Text Available Laser texturing is a relatively new multiprocess technique that has been used for machining 3D curved surfaces; it is more flexible and efficient to create decorative texture on 3D curved surfaces of injection molds so as to improve the surface quality and achieve cosmetic surface of molded plastic parts. In this paper, a novel method of laser texturing 3D curved surface based on 3-axis galvanometer scanning unit has been presented to prevent the texturing of injection mold surface from much distortion which is often caused by traditional texturing processes. The novel method has been based on the computer texture mapping technology which has been developed and presented. The developed texture mapping algorithm includes surface triangulation, notations, distortion measurement, control, and numerical method. An interface of computer texture mapping has been built to implement the algorithm of texture mapping approach to controlled distortion rate of 3D texture math model from 2D original texture applied to curvature surface. Through a case study of laser texturing of a high curvature surface of injection mold of a mice top case, it shows that the novel method of laser texturing meets the quality standard of laser texturing of injection mold.

Ion-beam texturing of uniaxially textured Ni films

International Nuclear Information System (INIS)

Park, S.J.; Norton, D.P.; Selvamanickam, Venkat

2005-01-01

The formation of biaxial texture in uniaxially textured Ni thin films via Ar-ion irradiation is reported. The ion-beam irradiation was not simultaneous with deposition. Instead, the ion beam irradiates the uniaxially textured film surface with no impinging deposition flux, which differs from conventional ion-beam-assisted deposition. The uniaxial texture is established via a nonion beam process, with the in-plane texture imposed on the uniaxial film via ion beam bombardment. Within this sequential ion beam texturing method, grain alignment is driven by selective etching and grain overgrowth

Li Zhi Peng

2016-01-01

Full Text Available In order to study the influence of pits’ size parameters on the tribological properties of textured friction pairs, using the Nd:YAG laser micro machining system and the “single pulse at the same point, interval more times” processing technics to process the pits on the surface of 45 steel. The dimension parameters of pits texture were obtained by orthogonal experimental design. The tribological experiment of GCr15 pin/45 steel disc was carried out by UMT-2 test machine. The surface morphology of the specimens was analyzed by using scanning electron microscopy. The experimental results show that the pits texture on the surface of 45 steel can effectively reduce the friction coefficient and the wear on the condition of oil-rich lubrication. The textured specimen with diameter 60μm, depth 6μm and surface density 10% has the lowest friction coefficient, and the friction coefficient is reduced by 21% compared with the smooth specimen. By analyzing the wear morphology on the surface of 45 steel, it is found that the surface of pits texture can obviously reduce the wear.

Narrative analysis: how students learn from stories of practice.

Science.gov (United States)

Edwards, Sharon Lorraine

2016-01-01

To describe and recommend a variety of data analysis methods when engaging in narrative research using story as an aid to nursing students' learning. Narrative research methodology is used in many nursing research studies. However, narrative research reports are generally unspecific regarding the analysis and interpretive process. This article examines the qualitative analytical approaches of Lieblich et al's ( 1998 ) narrative processes of holistic content and analysis of form, incorporated as overarching theories. To support these theories and to provide a more rounded analytical process, other authors' work is included. Approaching narrative analysis from different perspectives is recommended. For each cycle of analysis, it is important to conceptualise the analysis using descriptors drawn from the initial literature review and the initial text. Rigour and transparency are foremost, and tables are generated that reflect each stage of the analysis. The final stage of analysis is to clearly report, organise and present findings to reflect the richly varied and diverse potential of stories. Engaging in narrative research and then dealing with the large quantities of data to analyse can be daunting, difficult to manage and appear complex. It is also challenging and rewarding. With clear descriptors, examining the data using multiple lenses can serve to develop a greater level of insight into understanding nursing students' learning from their clinical experiences, presented as stories, when involved in the care of individuals. There are many approaches to narrative analysis in nursing research and it can be difficult to establish the main research approach best suited to the study. There is no single way to define narrative analysis and a combination of strategies can be applied.

Bulk rock elastic moduli at high pressures, derived from the mineral textures and from extrapolated laboratory data

International Nuclear Information System (INIS)

Ullemeyer, K; Keppler, R; Lokajíček, T; Vasin, R N; Behrmann, J H

2015-01-01

The elastic anisotropy of bulk rock depends on the mineral textures, the crack fabric and external parameters like, e.g., confining pressure. The texture-related contribution to elastic anisotropy can be predicted from the mineral textures, the largely sample-dependent contribution of the other parameters must be determined experimentally. Laboratory measurements of the elastic wave velocities are mostly limited to pressures of the intermediate crust. We describe a method, how the elastic wave velocity trends and, by this means, the elastic constants can be extrapolated to the pressure conditions of the lower crust. The extrapolated elastic constants are compared to the texture-derived ones. Pronounced elastic anisotropy is evident for phyllosilicate minerals, hence, the approach is demonstrated for two phyllosilicate-rich gneisses with approximately identical volume fractions of the phyllosilicates but different texture types.

Narrative Aversion: Challenges for the Illness Narrative Advocate.

Science.gov (United States)

Behrendt, Kathy

2017-02-01

Engaging in self-narrative is often touted as a powerful antidote to the bad effects of illness. However, there are various examples of what may broadly be termed "aversion" to illness narrative. I group these into three kinds: aversion to certain types of illness narrative; aversion to illness narrative as a whole; and aversion to illness narrative as an essentially therapeutic endeavor. These aversions can throw into doubt the advantages claimed for the illness narrator, including the key benefits of repair to the damage illness does to identity and life-trajectory. Underlying these alleged benefits are two key presuppositions: that it is the whole of one's life that is narratively unified, and that one's identity is inextricably bound up with narrative. By letting go of these assumptions, illness narrative advocates can respond to the challenges of narrative aversions. © The Author 2016.

2017-06-01

Full Text Available Background: After an occurrence of a Near-Death Experience (NDE, Near-Death Experiencers (NDErs usually report extremely rich and detailed narratives. Phenomenologically, a NDE can be described as a set of distinguishable features. Some authors have proposed regular patterns of NDEs, however, the actual temporality sequence of NDE core features remains a little explored area.Objectives: The aim of the present study was to investigate the frequency distribution of these features (globally and according to the position of features in narratives as well as the most frequently reported temporality sequences of features.Methods: We collected 154 French freely expressed written NDE narratives (i.e., Greyson NDE scale total score ≥ 7/32. A text analysis was conducted on all narratives in order to infer temporal ordering and frequency distribution of NDE features.Results: Our analyses highlighted the following most frequently reported sequence of consecutive NDE features: Out-of-Body Experience, Experiencing a tunnel, Seeing a bright light, Feeling of peace. Yet, this sequence was encountered in a very limited number of NDErs.Conclusion: These findings may suggest that NDEs temporality sequences can vary across NDErs. Exploring associations and relationships among features encountered during NDEs may complete the rigorous definition and scientific comprehension of the phenomenon.

TEXTURAL, FLOW AND SENSORY PROPERTIES OF FIVE “FRUZELINA” WITH SOUR CHERRIES

Directory of Open Access Journals (Sweden)

Irena Bojdo Tomasiak

2010-05-01

Full Text Available Gel with sour cherries called “Fruzelina” is a new product in the Polish market widely used in food industry as a decorative element or filling for pastries, as an ingredient in fruit desserts, as an additive to ice creams, whipped cream and waffles. The cherry gels are the product prepared using different types of chemically modified starches. Starch is an additive used to ensure rich and short texture and high viscosity of “Fruzelina”. Food texture and viscosity may be measured by senses and instrumentally. Because of fact that sensory analysis is time consuming and very costly, it is easier and cheaper to determine food properties, especially their texture and flow behaviour by appropriate mechanical tests. The aim of this work was to study the rheological behavior of five cherry gels and evaluate the correlation between textural, flow and sensory properties of these gels measured instrumentally and by human senses. The back extrusion test has been found to be applicable to study the textural properties of cherry gels. There was high positive correlation between gel texture measured by senses and texture parameters measured in back extrusion test. Similar high correlation was identified for consistency coefficient K obtained in Ostwald de Waele model and gel texture assessed by sensory panel. It was found that values of sensory parameters such as taste and odour decreased as the rheological parameters increased. High negative correlations were observed in these cases. Therefore, instrumental measurements can be alternative for more expensive sensory methods. doi:10.5219/53

LOCAL TEXTURE DESCRIPTION FRAMEWORK FOR TEXTURE BASED FACE RECOGNITION

Directory of Open Access Journals (Sweden)

R. Reena Rose

2014-02-01

Full Text Available Texture descriptors have an important role in recognizing face images. However, almost all the existing local texture descriptors use nearest neighbors to encode a texture pattern around a pixel. But in face images, most of the pixels have similar characteristics with that of its nearest neighbors because the skin covers large area in a face and the skin tone at neighboring regions are same. Therefore this paper presents a general framework called Local Texture Description Framework that uses only eight pixels which are at certain distance apart either circular or elliptical from the referenced pixel. Local texture description can be done using the foundation of any existing local texture descriptors. In this paper, the performance of the proposed framework is verified with three existing local texture descriptors Local Binary Pattern (LBP, Local Texture Pattern (LTP and Local Tetra Patterns (LTrPs for the five issues viz. facial expression, partial occlusion, illumination variation, pose variation and general recognition. Five benchmark databases JAFFE, Essex, Indian faces, AT&T and Georgia Tech are used for the experiments. Experimental results demonstrate that even with less number of patterns, the proposed framework could achieve higher recognition accuracy than that of their base models.

Ion beam texturing

Hudson, W. R.

1977-01-01

A microscopic surface texture was created by sputter-etching a surface while simultaneously sputter-depositing a lower sputter yield material onto the surface. A xenon ion-beam source was used to perform the texturing process on samples as large as 3-cm diameter. Textured surfaces have been characterized with SEM photomicrographs for a large number of materials including Cu, Al, Si, Ti, Ni, Fe, stainless steel, Au, and Ag. A number of texturing parameters are studied including the variation of texture with ion-beam powder, surface temperature, and the rate of texture growth with sputter etching time.

The authors describe a computer procedure which allows them to introduce experimental initial textures as starting conditions for texture simulation (instead of a theoretical random texture). They apply the procedure on two batches of copper with weak initial textures and on fine-grained and coarse......-grained aluminium with moderately strong initial textures. In copper the initial texture turns out to be too weak to have any significant effect. In aluminium the initial texture has a very significant effect on the simulated textures-similar to the effect it has on the experimental textures.

Possible future applications of the procedure are discussed...

Framing Effects in Narrative and Non-Narrative Risk Messages.

Science.gov (United States)

Steinhardt, Joseph; Shapiro, Michael A

2015-08-01

Narrative messages are increasingly popular in health and risk campaigns, yet gain/loss framing effects have never been tested with such messages. Three experiments examined framing in narrative messages. Experiment 1 found that only the character's decision, not framing, influenced judgments about characters in a narrative derived from a prospect theory context. Experiment 2 found that a framing effect that occurred when presented in a decision format did not occur when the same situation was presented as a narrative. Using a different story/decision context, Experiment 3 found no significant difference in preference for surgery over radiation therapy in a narrative presentation compared to a non-narrative presentation. The results suggest that health and risk campaigns cannot assume that framing effects will be the same in narrative messages and non-narrative messages. Potential reasons for these differences and suggestions for future research are discussed. © 2015 Society for Risk Analysis.

Mamat, Hasmadi; Hill, Sandra E

2014-09-01

Fat is an important ingredient in baking products and it plays many roles in providing desirable textural properties of baking products, particularly biscuit. In this study, the effect of fat types on dough rheological properties and quality of semi-sweet biscuit (rich tea type) were investigated using various techniques. Texture profile and extensibility analysis were used to study the dough rheology, while three-point bend test and scanning electron microscopy were used to analyse the textural characteristics of final product. TPA results showed that the type of fat significantly influenced dough textural properties. Biscuit produced with higher solid fat oil showed higher breaking force but this was not significantly different when evaluated by sensory panel. Scanning electron microscopy showed that biscuit produced with palm mid-fraction had an open internal microstructure and heterogeneous air cells as compared to other samples.

Combining fine texture and coarse color features for color texture classification

Science.gov (United States)

Wang, Junmin; Fan, Yangyu; Li, Ning

2017-11-01

Color texture classification plays an important role in computer vision applications because texture and color are two fundamental visual features. To classify the color texture via extracting discriminative color texture features in real time, we present an approach of combining the fine texture and coarse color features for color texture classification. First, the input image is transformed from RGB to HSV color space to separate texture and color information. Second, the scale-selective completed local binary count (CLBC) algorithm is introduced to extract the fine texture feature from the V component in HSV color space. Third, both H and S components are quantized at an optimal coarse level. Furthermore, the joint histogram of H and S components is calculated, which is considered as the coarse color feature. Finally, the fine texture and coarse color features are combined as the final descriptor and the nearest subspace classifier is used for classification. Experimental results on CUReT, KTH-TIPS, and New-BarkTex databases demonstrate that the proposed method achieves state-of-the-art classification performance. Moreover, the proposed method is fast enough for real-time applications.

Participatory theatre and mental health recovery: a narrative inquiry.

To identify the potential relationship between participation in theatre and mental health recovery. To give voice to the stories told by participants of Teater Vildenvei, a theatre company that has been part of the rehabilitation programme for mental health service users in Oslo since 1995. Twelve narrative interviews were conducted among participants of Teater Vildenvei, and the data were subject to a narrative analysis process following the philosophy of Paul Ricoeur and the specific methods of thematic, event and relational analysis as identified by Riessman. The narratives are considered in the theoretical light of the mental health recovery framework as identified by Leamy et al. Each participant had experienced a transformation in identity; the sense of belonging within the group was perceived as highly important to their mental health; engagement with the theatre company gives people something meaningful to do, a sense of hope and individuals feel empowered. This narrative inquiry gave opportunity for participants to elaborate on their stories of their engagement with Teater Vildenvei. It is through the richness of the data that the depth of the significance of meaning that people ascribe to their stories demonstrates the potential power of participatory theatre for mental health recovery. Because of its effects, people make life-changing and life-saving claims.

Terrill, Lauren; Gullifer, Judith

2010-07-01

This study explored experiences of eight rural, Anglo-Australian women aged between 65 and 75 using semi-structured interviews. Thematic analysis revealed three prominent themes: (a) the free and busy me highlights the increased freedom in later life enabling choices regarding activities the women would like to engage in; (b) the secret is being positive and pragmatic emphasizes the importance of adopting a pragmatic acceptance of growing older; and (c) narratives of growth and stagnation highlights the pursuit of growth among older women in order to enhance the current self. Findings emphasize the construction of later life as one of liberation, resilience and growth.

Narrativity and enaction: the social nature of literary narrative understanding.

Science.gov (United States)

Popova, Yanna B

2014-01-01

This paper proposes an understanding of literary narrative as a form of social cognition and situates the study of such narratives in relation to the new comprehensive approach to human cognition, enaction. The particular form of enactive cognition that narrative understanding is proposed to depend on is that of participatory sense-making, as developed in the work of Di Paolo and De Jaegher. Currently there is no consensus as to what makes a good literary narrative, how it is understood, and why it plays such an irreplaceable role in human experience. The proposal thus identifies a gap in the existing research on narrative by describing narrative as a form of intersubjective process of sense-making between two agents, a teller and a reader. It argues that making sense of narrative literature is an interactional process of co-constructing a story-world with a narrator. Such an understanding of narrative makes a decisive break with both text-centered approaches that have dominated both structuralist and early cognitivist study of narrative, as well as pragmatic communicative ones that view narrative as a form of linguistic implicature. The interactive experience that narrative affords and necessitates at the same time, I argue, serves to highlight the active yet cooperative and communal nature of human sociality, expressed in the many forms than human beings interact in, including literary ones.

Texture Analysis of satellite imagery in the field of biodiversity and forest structure of the Colombian Andes

International Nuclear Information System (INIS)

Anaya A, Jesus A; Duque L, Rosa A; Valencia H, German M

2008-01-01

The relationship between texture calculated from an Ikonos image with diversity and structure was evaluated along a corridor with 43 field plots in the Colombian Andes. Diversity indexes were calculated at the 43 plots and Land Use maps were used as an approach to vegetation structure. Texture was obtained from an Ikonos image using Gray Level Co-occurrence Matrix GLCM and Gray Level Difference Vector GLDV. Traditionally, texture has been interpreted from a qualitatively point of view from smooth to rough, however our approach using a matrix allows for a quantitative measurement. Texture was related to field information at two different detail levels: first with diversity measurements (Shannon Index and Richness) established at forest plots and second, with classes of a land use map (primary forest, secondary forests, forest plantation, crops and pastures) considered to be representative of vegetation structure. Results are based on relations between structure diversity,texture diversity and texture structure. Ikonos texture presents a large potential to classify forests at different successional stages however, the relation between diversity and data gathered with remote sensing is still weak. Landsat images are mentioned throughout the text as a reference or comparison with Ikonos images.

TEXTURAL FRACTOGRAPHY

Full Text Available The reconstitution of the history of a fatigue process is based on the knowledge of any correspondences between the morphology of the crack surface and the velocity of the crack growth (crack growth rate - CGR. The textural fractography is oriented to mezoscopic SEM magnifications (30 to 500x. Images contain complicated textures without distinct borders. The aim is to find any characteristics of this texture, which correlate with CGR. Pre-processing of images is necessary to obtain a homogeneous texture. Three methods of textural analysis have been developed and realized as computational programs: the method based on the spectral structure of the image, the method based on a Gibbs random field (GRF model, and the method based on the idealization of light objects into a fibre process. In order to extract and analyze the fibre process, special methods - tracing fibres and a database-oriented analysis of a fibre process - have been developed.

Multi-Parametric MRI and Texture Analysis to Visualize Spatial Histologic Heterogeneity and Tumor Extent in Glioblastoma.

Directory of Open Access Journals (Sweden)

Leland S Hu

Full Text Available Genetic profiling represents the future of neuro-oncology but suffers from inadequate biopsies in heterogeneous tumors like Glioblastoma (GBM. Contrast-enhanced MRI (CE-MRI targets enhancing core (ENH but yields adequate tumor in only ~60% of cases. Further, CE-MRI poorly localizes infiltrative tumor within surrounding non-enhancing parenchyma, or brain-around-tumor (BAT, despite the importance of characterizing this tumor segment, which universally recurs. In this study, we use multiple texture analysis and machine learning (ML algorithms to analyze multi-parametric MRI, and produce new images indicating tumor-rich targets in GBM.We recruited primary GBM patients undergoing image-guided biopsies and acquired pre-operative MRI: CE-MRI, Dynamic-Susceptibility-weighted-Contrast-enhanced-MRI, and Diffusion Tensor Imaging. Following image coregistration and region of interest placement at biopsy locations, we compared MRI metrics and regional texture with histologic diagnoses of high- vs low-tumor content (≥80% vs <80% tumor nuclei for corresponding samples. In a training set, we used three texture analysis algorithms and three ML methods to identify MRI-texture features that optimized model accuracy to distinguish tumor content. We confirmed model accuracy in a separate validation set.We collected 82 biopsies from 18 GBMs throughout ENH and BAT. The MRI-based model achieved 85% cross-validated accuracy to diagnose high- vs low-tumor in the training set (60 biopsies, 11 patients. The model achieved 81.8% accuracy in the validation set (22 biopsies, 7 patients.Multi-parametric MRI and texture analysis can help characterize and visualize GBM's spatial histologic heterogeneity to identify regional tumor-rich biopsy targets.

2010-06-01

Out of the complex influences of event, narrative and listener characteristics on narrative emotions, this paper focuses on event severity, narrative perspectives, mood, and dispositions for emotion regulation and empathy. Event severity and perspective representation were systematically varied in sad autobiographical narratives to study their influence on quantity and quality of readers' emotional response. Each of three stories were manipulated to contain elaborated perspectives, only the past protagonists' perspective (dramatic narration), and very little perspectives at all (impersonal narration). We predicted that event severity influences the quantity of emotional response, while degree of perspective representation influences plausibility and whether emotional responses are sympathetic or interactional, that is, directed against the narrator. Hypotheses were confirmed except for plausibility, and perspective representation had an effect only on anger against and dislike of the narrator. In a second study, impersonal narration evoked anger at and negative evaluations of the narrator which were related to blaming the narrator for showing too little emotional involvement. The generalizability of findings across emotions and implications for sharing of emotions in everyday and clinical settings are discussed.

2013-11-01

Full Text Available Introduction: Consumers preferences for solid food are, for the majority of foods groups, influenced by their textural properties. Romanian traditional cuisine is rich in meat foods and therefore this food group has an important contribution to the total mineral intake as well as the ingestion of potentially toxic metals such as Cd and Pb. Although beef liver is an important source of minerals for human consumption, its concentrations in Cd and Pb and heterogeneous textural properties may hinder its acceptability. Aims: The purpose of the work was to estimate raw and cooked beef meat and offal mineral quality including Cd and Pb concentrations and their contribution to a balanced human diet and health  as well as the influenced of thermal preparation on their mineral and textural properties. Materials and methods:  Beef liver, kidney and longissimus dorsi muscle were bought from local markets. Thermal preparation was conducted by microwave and boiling with no water contact. Texture profile analyses was conducted for quantifying textural properties such as  Hardness, Cohesiveness, Springiness, Springiness Index, Chewiness, Adhesiveness and Stiffness. The mineral concentrations of the raw and cooked samples were analyzed by ICP-MS. Conclusion: The offal textural parameters variability was very large within the same organ and compared to the muscle textural parameters variability too. Muscle and offal thermal preparation strongly influenced their minerals’ concentrations as well as their textural properties. Thermal preparation significantly decreased beef liver and kidney samples’ total K and Na concentrations. It is suggested that for improving beef liver acceptability, the consumer has to be advised on the influence of the thermal preparation on beef liver parts’ textural properties as well as minerals concentrations.

Pedagogical Dramas and Transformational Play: Realizing Narrative through Videogames Design

Whereas traditionally stories involve an author, a performer, and an audience, much of the power of videogames as media for advancing narrative springs from their affordance for the player to occupy more than one role—and sometimes all three—simultaneously. In the narratively-rich videogames that we design, players have the opportunity to perform actions, experience consequences, and reflect on the underlying social values that these situations were designed to engage. Here, our focus is on the use of these games to engage children in experiencing ideological struggles associated with realizing social commitments. Toward this end, we will present our theoretical argument for the power of games as a contemporary story medium, grounding this discussion in the demonstration of three game design projects and their implementations.

Full Text Available ake found footage horror films have been massively made in the last two decades. To shoot a fictional script and give to it the texture of a documentary, a filmmaker has to deal with a number of creative restrictions in order to impose to images and sounds an effect of reality present in amateur footage. This essay examines recurring patterns of style, in this subgenre of movies, which have been used to combine narrative clarity and documental verisimilitude – a combination imposed by the presence of recording devices on the diegesis. 

Narrative interviewing.

Anderson, Claire; Kirkpatrick, Susan

2016-06-01

Introduction Narrative interviews place the people being interviewed at the heart of a research study. They are a means of collecting people's own stories about their experiences of health and illness. Narrative interviews can help researchers to better understand people's experiences and behaviours. Narratives may come closer to representing the context and integrity of people's lives than more quantitative means of research. Methodology Researchers using narrative interview techniques do not set out with a fixed agenda, rather they tend to let the interviewee control the direction, content and pace of the interview. The paper describes the interview process and the suggested approach to analysis of narrative interviews, We draw on the example from a study that used series of narrative interviews about people's experiences of taking antidepressants. Limitations Some people may find it particularly challenging to tell their story to a researcher in this way rather than be asked a series of questions like in a television or radio interview. Narrative research like all qualitative research does not set out to be generalisable and may only involve a small set of interviews.

Testing narrative engagement theory, this study examines student engagement and teachers’ spontaneous narratives told in a narrative-based drug prevention curriculum. The study describes the extent to which teachers share their own narratives in a narrative-based curriculum, identifies dominant narrative elements, forms and functions, and assesses the relationships among teacher narratives, overall lesson narrative quality, and student engagement. One hundred videotaped lessons of the keepin’ it REAL drug prevention curriculum were coded and the results supported the claim that increased narrative quality of a prevention lesson would be associated with increased student engagement. The quality of narrativity, however, varied widely. Implications of these results for narrative-based prevention interventions and narrative pedagogy are discussed. PMID:26690668

A collaborative narrative inquiry: Two teacher educators learning about narrative inquiry

Barkhuizen, Gary

2009-12-01

Full Text Available With its capacity to unharness the power of narrative to promote meaning-making of lived experience, narrative inquiry is developing as a credible approach to research in several areas in the field of language teaching (Johnson, 2006. This article tells the story of two narrative researchers working in language teacher education who engaged in a collaborative narrative inquiry as both participants and inquirers, in order to learn more about narrative inquiry. The ‘bounded’ nature of their inquiry design provided a feasible way for them to explore their focus of research (i.e. their learning about narrative inquiry, and led them, through an iterative and reflexive process of analysing their narrative data, to formulate what they believe are essential ingredients of principled narrative inquiry work. Four narrative inquiry variables became the scaffolding which enabled them to answer their research questions, and are offered here as a heuristic for teaching practitioners, whether they be teachers, teacher educators or researchers, to guide them in narrative inquiries into their own work.

We have theoretically investigated the spin inelastic scattering of helical electrons off a high-spin nanomagnet absorbed on a topological surface. The nanomagnet is treated as a dynamic quantum spin and driven by the spin transfer torque effect. We proposed a mechanism to electrically manipulate the spin texture of helical Dirac fermions rather than by an external magnetic field. By tuning the bias voltage and the direction of impurity magnetization, we present rich patterns of spin texture, from which important fingerprints exclusively associated with the spin helical feature are obtained. Furthermore, it is found that the nonmagnetic potential can create the resonance state in the spin density with different physics as the previously reported resonance of charge density.

Full Text Available The purpose of the present study was to compare the effects of two different teaching methods on students' comprehension during Physical Education lesson: narration versus animation with concurrent narration, during teaching shot put event. Thirty primary school children (boys and girls volunteered to participate in this study. In experiment students listened (narration and viewed (animation with narration the presentation of two shot putting styles. A problem-solving and a retention test were used to evaluate students' comprehension. Results showed that students' comprehension was better when shot putting styles were presented through a mixed model (animation and narration group than a single (narration. The animation with concurrent narration group performed better than the narration group, in problem-solving (M = 4.91, SD = 1.36 and in retention test (M = 5.98, SD = 1.28 t(28 = 1.89 p<0.01. An instructional implication is that pictures with words is more effective way of teaching when they occur continuingly in time, than only words during Physical Education lesson.

Lev-Wiesel, Rachel; Liraz, Revital

2007-01-01

The study aimed to examine the extent to which the use of drawing prior to narrative description increases the richness of the narrative given by children who are exposed to a succession of negative life events. The sample consisted of study and comparison groups (60 children: 27 boys, 33 girls), ranging in age from 9 to 14, whose fathers were addicted to drugs. The study group was asked to first 'draw your life in the shadow of your father's addiction to drugs', then verbally describes 'your life under the shadow of an addicted father'; the comparison group was asked only the latter. Following evaluation of drawings and narratives by two judges, analysis of variance between the groups' narratives revealed that when children were first asked to draw, their narratives were more detailed and more revealing of emotions compared to children who were asked only to verbally describe their lives, whereas expressions of resistance and splitting were more apparent in the comparison group.

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

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.

Genetic profiling represents the future of neuro-oncology but suffers from inadequate biopsies in heterogeneous tumors like Glioblastoma (GBM). Contrast-enhanced MRI (CE-MRI) targets enhancing core (ENH) but yields adequate tumor in only ~60% of cases. Further, CE-MRI poorly localizes infiltrative tumor within surrounding non-enhancing parenchyma, or brain-around-tumor (BAT), despite the importance of characterizing this tumor segment, which universally recurs. In this study, we use multiple texture analysis and machine learning (ML) algorithms to analyze multi-parametric MRI, and produce new images indicating tumor-rich targets in GBM. We recruited primary GBM patients undergoing image-guided biopsies and acquired pre-operative MRI: CE-MRI, Dynamic-Susceptibility-weighted-Contrast-enhanced-MRI, and Diffusion Tensor Imaging. Following image coregistration and region of interest placement at biopsy locations, we compared MRI metrics and regional texture with histologic diagnoses of high- vs low-tumor content (≥80% vs heterogeneity to identify regional tumor-rich biopsy targets.

Visual narrative structure.

Cohn, Neil

2013-04-01

Narratives are an integral part of human expression. In the graphic form, they range from cave paintings to Egyptian hieroglyphics, from the Bayeux Tapestry to modern day comic books (Kunzle, 1973; McCloud, 1993). Yet not much research has addressed the structure and comprehension of narrative images, for example, how do people create meaning out of sequential images? This piece helps fill the gap by presenting a theory of Narrative Grammar. We describe the basic narrative categories and their relationship to a canonical narrative arc, followed by a discussion of complex structures that extend beyond the canonical schema. This demands that the canonical arc be reconsidered as a generative schema whereby any narrative category can be expanded into a node in a tree structure. Narrative "pacing" is interpreted as a reflection of various patterns of this embedding: conjunction, left-branching trees, center-embedded constituencies, and others. Following this, diagnostic methods are proposed for testing narrative categories and constituency. Finally, we outline the applicability of this theory beyond sequential images, such as to film and verbal discourse, and compare this theory with previous approaches to narrative and discourse.

Narrative means to manage responsibility in life narratives across adolescence.

De Silveira, Cybèle; Habermas, Tilmann

2011-01-01

Adolescence is a passage from dependence to adult responsibility. Alongside identity development, social-cognitive development, and the ability to construct a life story, adolescents become increasingly aware of both their potential responsibility in an expanded sphere of life and of complex, contextual influences on their lives. This was partially tested in a cross-sectional study, both in terms of linguistic means and content expressed in life narratives. Indicators were defined for narrative agency, grading of responsibility, serendipity, and turning points, and tested for age differences in relative frequencies in 102 life narratives from age groups of 8, 12, 16, and 20 years, balanced for gender. Narrative grading of responsibility, serendipity, and turning points increased throughout adolescence. The relative frequency of narrative agency, in contrast, remained constant across age groups. Results are interpreted in the context of adolescent development of narrative identity.

2018-07-01

Although communication with patients is essential to health care, education designed to develop patient-centred communication often ignores patients' voices. Patient stories may offer a means to explore patient experiences to inform patient-centred communication skills education design. Our research questions were: (i) What are the features of patients' health care communication narratives? (ii) What differences exist between patient narratives evaluated as positive and those evaluated as negative? (iii) How do patients narrate emotion in their narratives? This interpretivist research was underpinned by social constructionism. We employed a narrative approach to design an online questionnaire that was advertised to patients in the community. Analysis of the stories that were generated involved analysis of what was written (i.e. framework analysis) and of how it was written (i.e. attending to linguistic features). Participants shared 180 written narratives about previous health care professional (HCP) communication interactions. Narratives commonly included those of female patients seeking help for musculoskeletal or psychological concerns, which most frequently had occurred within the previous 6 months with male general practitioners in community settings. Framework analysis revealed four key themes: (i) patient actions during consultations; (ii) patient actions afterwards; (iii) lasting legacy, and (iv) interpersonal factors. Patients in narratives evaluated as positive actively engaged during and after interactions, had ongoing positive relationships with HCPs and felt valued in these relationships. Patients in narratives evaluated as negative were either passive or active during the interaction, but mostly failed to return to the HCP and felt devalued in their interaction. Further analysis of the linguistic features of select narratives revealed rich constructions of positive and negative emotions emphasising the lasting legacies of these interactions. Analysis

Semantic attributes based texture generation

2018-04-01

Semantic attributes are commonly used for texture description. They can be used to describe the information of a texture, such as patterns, textons, distributions, brightness, and so on. Generally speaking, semantic attributes are more concrete descriptors than perceptual features. Therefore, it is practical to generate texture images from semantic attributes. In this paper, we propose to generate high-quality texture images from semantic attributes. Over the last two decades, several works have been done on texture synthesis and generation. Most of them focusing on example-based texture synthesis and procedural texture generation. Semantic attributes based texture generation still deserves more devotion. Gan et al. proposed a useful joint model for perception driven texture generation. However, perceptual features are nonobjective spatial statistics used by humans to distinguish different textures in pre-attentive situations. To give more describing information about texture appearance, semantic attributes which are more in line with human description habits are desired. In this paper, we use sigmoid cross entropy loss in an auxiliary model to provide enough information for a generator. Consequently, the discriminator is released from the relatively intractable mission of figuring out the joint distribution of condition vectors and samples. To demonstrate the validity of our method, we compare our method to Gan et al.'s method on generating textures by designing experiments on PTD and DTD. All experimental results show that our model can generate textures from semantic attributes.

Connecting the Links: Narratives, Simulations and Serious Games in Prehospital Training.

Due to rapid and substantial changes in the health sector, collaboration and supporting technologies get more into focus. Changes in education and training are also required. Simulations and serious games (SSG) are often advocated as promising technologies supporting training of many and in the same manner, or increasing the skills necessary to deal with new, dangerous, complex or unexpected situations. The aim of this paper is to illustrate and discuss resources needed for planning and performing collaborative contextual training scenarios. Based on a practical study involving prehospital nurses and different simulator technologies the often-recurring activity chains in prehospital training were trained. This paper exemplifies the benefit of using narratives and SSGs for contextual training contributing to higher user experiences. The benefits of using simulation technologies aligned by processes can be easier defined by narratives from practitioners. While processes help to define more efficient and effective training, narratives and SSGs are beneficial to design scenarios with clues for higher user experiences. By discussing illustrative examples, the paper contributes to better understanding of how to plan simulation-technology rich training scenarios.

Why might you use narrative methodology? A story about narrative

Directory of Open Access Journals (Sweden)

Lynn McAlpine

2016-04-01

Full Text Available Narrative is one of many qualitative methodologies that can be brought to bear in collecting and analysing data and reporting results, though it is not as frequently used as say in case studies. This article provides a window into its use, from the perspective of a researcher who has used it consistently over the past decade to examine early career researcher experience – doctoral students, and those who have completed their degrees and are advancing their careers. This experience has contributed to a robust understanding of the potential of narrative, as well as its limitations. This paper first lays out the broad landscape of narrative research and then makes transparent the thinking, processes and procedures involved in the ten-year narrative study including the potential for creativity that narrative invites. The goal is to engage other researchers to consider exploring the use of narrative – if it aligns with their epistemological stance.

Losing the Plot: Narrative, Counter-Narrative and Violent Extremism

Directory of Open Access Journals (Sweden)

Andrew Glazzard

2017-05-01

Full Text Available Counter-terrorist practitioners and policy makers appear to be very interested in narrative. They often describe the worldview of violent Islamist groups and movements as the ‘jihadi narrative’, while their efforts to confront terrorist propaganda are usually labelled as ‘counter-narrative’ or ‘alternative narrative’. However, while the counter-narrative approach has gained widespread acceptance in governments, think-tanks and civil society organisations, it is built on very shaky theoretical and empirical foundations. Some valuable theoretical contributions to the study of violent extremist narrative have been made by psychologists in particular, but there is one discipline which is conspicuous by its absence from the field: literary studies. This paper makes a case for the value of studying violent extremist narratives as narratives in the literary sense. By employing the tools and techniques of literary criticism, violent extremist communication can be revealed as not only potentially persuasive, but also creative and aesthetically appealing: terrorists inspire their followers, they don’t merely persuade them. Understanding the creative sources of this inspiration is vital if counter-narrative is to succeed in presenting an alternative to the propaganda of violent extremist groups.

Textural and mineral chemistry constraints on evolution of Merapi Volcano, Indonesia

2013-07-01

We analyze and compare the textures of Merapi lavas (basalts and basaltic andesites) ranging in age from Proto-Merapi through modern activity, with the goal of gaining insights on the temporal evolution of Merapi's magmatic system. Analysis of textural parameters, such as phenocryst and microphenocryst crystallinity, coupled with crystal size distribution theory, provides information about the storage and transport of magmas. We combine textural analyses with geochemical investigations for a comprehensive comparison of erupted lavas over time. The chemical analyses identify crystal growth processes in magma chambers and underline differences between sample groups. Our work suggests the occurrence of two distinct histories, presumably associated with (at least) two generally distinct types of rheological behaviors and storage/transport systems. These behaviors are associated with different plagioclase growth patterns, with both groups influenced by late-stage shallow decompression degassing-induced microlite crystallization. Both groups contain amphibole crystals that indicate an early period of mid-crustal to deep-crustal storage of water-rich magmas. Dome lavas from the 20th century eruptive activity indicate quasi-steady-state nucleation-and-growth evolution interspersed with episodes of reheating and textural coarsening, suggesting residence in magma storage at multiple depths, both > 10 km, and conditions. These observations, coupled with our companion study of Merapi tephra samples, suggest that the relatively benign type of activity observed in the 20th century will be interrupted from time to time in the future by more explosive eruptions, such as that of 2010.

We examine the flavor structure of the trilinear superpotential couplings which can result from embedding the Standard Model within D-brane sectors in Type IIB orientifold models, which are examples within the Type I string framework. We find in general that the allowed flavor structures of the Yukawa coupling matrices to leading order are given by basic variations on the d emocratic'' texture ansatz. In certain interesting cases, the Yukawa couplings have a novel structure in which a single right-handed fermion couples democratically at leading order to three left-handed fermions.

Full Text Available With the emerging trend of patient family–centered care in health care, it is essential that physicians be exposed to patient and family perspectives of care during medical education and training. Grand Rounds provides an ideal format for physicians to learn about patient family–centered care. At Brigham and Women’s Hospital, we sought to bring the voice of the patient to Patient Family–Centered Grand Rounds in order to expose clinicians to rich narratives describing the medical care received by patients/families and to ultimately change physician practice to reflect patient family–centered principles. We conducted a clinician survey and found promising results indicating that patient/family narratives can be effective at educating physicians about patient family–centered care.

Aesthetic Perception of Visual Textures: A Holistic Exploration using Texture Analysis, Psychological Experiment and Perception Modeling

Full Text Available Modeling human aesthetic perception of visual textures is important and valuable in numerous industrial domains, such as product design, architectural design and decoration. Based on results from a semantic differential rating experiment, we modeled the relationship between low-level basic texture features and aesthetic properties involved in human aesthetic texture perception. First, we compute basic texture features from textural images using four classical methods. These features are neutral, objective and independent of the socio-cultural context of the visual textures. Then, we conduct a semantic differential rating experiment to collect from evaluators their aesthetic perceptions of selected textural stimuli. In semantic differential rating experiment, eights pairs of aesthetic properties are chosen, which are strongly related to the socio-cultural context of the selected textures and to human emotions. They are easily understood and connected to everyday life. We propose a hierarchical feed-forward layer model of aesthetic texture perception and assign 8 pairs of aesthetic properties to different layers. Finally, we describe the generation of multiple linear and nonlinear regression models for aesthetic prediction by taking dimensionality-reduced texture features and aesthetic properties of visual textures as dependent and independent variables, respectively. Our experimental results indicate that the relationships between each layer and its neighbors in the hierarchical feed-forward layer model of aesthetic texture perception can be fitted well by linear functions, and the models thus generated can successfully bridge the gap between computational texture features and aesthetic texture properties.

[Visual Texture Agnosia in Humans].

Suzuki, Kyoko

Visual object recognition requires the processing of both geometric and surface properties. Patients with occipital lesions may have visual agnosia, which is impairment in the recognition and identification of visually presented objects primarily through their geometric features. An analogous condition involving the failure to recognize an object by its texture may exist, which can be called visual texture agnosia. Here we present two cases with visual texture agnosia. Case 1 had left homonymous hemianopia and right upper quadrantanopia, along with achromatopsia, prosopagnosia, and texture agnosia, because of damage to his left ventromedial occipitotemporal cortex and right lateral occipito-temporo-parietal cortex due to multiple cerebral embolisms. Although he showed difficulty matching and naming textures of real materials, he could readily name visually presented objects by their contours. Case 2 had right lower quadrantanopia, along with impairment in stereopsis and recognition of texture in 2D images, because of subcortical hemorrhage in the left occipitotemporal region. He failed to recognize shapes based on texture information, whereas shape recognition based on contours was well preserved. Our findings, along with those of three reported cases with texture agnosia, indicate that there are separate channels for processing texture, color, and geometric features, and that the regions around the left collateral sulcus are crucial for texture processing.

Feature-aware natural texture synthesis

KAUST Repository

Wu, Fuzhang

2014-12-04

This article presents a framework for natural texture synthesis and processing. This framework is motivated by the observation that given examples captured in natural scene, texture synthesis addresses a critical problem, namely, that synthesis quality can be affected adversely if the texture elements in an example display spatially varied patterns, such as perspective distortion, the composition of different sub-textures, and variations in global color pattern as a result of complex illumination. This issue is common in natural textures and is a fundamental challenge for previously developed methods. Thus, we address it from a feature point of view and propose a feature-aware approach to synthesize natural textures. The synthesis process is guided by a feature map that represents the visual characteristics of the input texture. Moreover, we present a novel adaptive initialization algorithm that can effectively avoid the repeat and verbatim copying artifacts. Our approach improves texture synthesis in many images that cannot be handled effectively with traditional technologies.

FCC Rolling Textures Reviewed in the Light of Quantitative Comparisons between Simulated and Experimental Textures

The crystallographic texture of metallic materials has a very strong effect on the properties of the materials. In the present article, we look at the rolling textures of fcc metals and alloys, where the classical problem is the existence of two different types of texture, the "copper-type texture......" and the "brass-type texture." The type of texture developed is determined by the stacking fault energy of the material, the rolling temperature and the strain rate of the rolling process. Recent texture simulations by the present authors provide the basis for a renewed discussion of the whole field of fcc......} slip without or with deformation twinning, but we also consider slip on other slip planes and slip by partial dislocations. We consistently make quantitative comparison of the simulation results and the experimental textures by means of a scalar correlation factor. We find that the development...

Narrative and Institutional Economics

Vyacheslav V. Volchik

2017-12-01

Full Text Available This article addresses a range of questions associated with the occurrence of a new field of study – narrative economics, which is considered in the context of modern institutionalism. Pioneering works of R. Shiller, G. Akerlof and D. Snower spotlighted the importance of analyzing narratives and narrative influence when studying economic processes. In this paper, a qualitative study of narratives is seen through the prism of an answer to the question: «How do prescribed narratives influence institutions and change them? ». Narratives have much in common with institutions since very often, explicitly or implicitly, they contain value judgements about social interactions or normative aspects shaping behavioral patterns. The identification of dominating narratives enables us to understand better how institutions influence economic (social action. Repeated interactions among social actors are structured through understanding and learning the rules. Understanding of social rules comes from the language – we articulate and perceive the rules drawing on common narratives. Narratives and institutions are helpful when actors gain knowledge about various forms of social communication. Digital technologies, mass media and social networking sites facilitate the spread of narratives, values and beliefs; this process is characterized by increasing returns. Studying narratives and institutions is crucial for modern economic theory because it helps to improve qualitative and quantitative methods of analyzing empirical evidence and enables researchers to understand complex economic processes.

Seismic texture classification. Final report

Energy Technology Data Exchange (ETDEWEB)

Vinther, R.

1997-12-31

The seismic texture classification method, is a seismic attribute that can both recognize the general reflectivity styles and locate variations from these. The seismic texture classification performs a statistic analysis for the seismic section (or volume) aiming at describing the reflectivity. Based on a set of reference reflectivities the seismic textures are classified. The result of the seismic texture classification is a display of seismic texture categories showing both the styles of reflectivity from the reference set and interpolations and extrapolations from these. The display is interpreted as statistical variations in the seismic data. The seismic texture classification is applied to seismic sections and volumes from the Danish North Sea representing both horizontal stratifications and salt diapers. The attribute succeeded in recognizing both general structure of successions and variations from these. Also, the seismic texture classification is not only able to display variations in prospective areas (1-7 sec. TWT) but can also be applied to deep seismic sections. The seismic texture classification is tested on a deep reflection seismic section (13-18 sec. TWT) from the Baltic Sea. Applied to this section the seismic texture classification succeeded in locating the Moho, which could not be located using conventional interpretation tools. The seismic texture classification is a seismic attribute which can display general reflectivity styles and deviations from these and enhance variations not found by conventional interpretation tools.

Presence of textures in the metal uranium fuel is harmful because of anisotropy properties of uranium during thermal treatment, and especially during irradiation. Anisotropic radiation swelling of uranium can cause deformation of fuel element due to existence of textures. The objective of this work was studying of the influence of phase transformations on textures in uranium which has undergone plastic deformation due to rotational casting. Dilatometry method was adopted for testing the textures. This report describes the device for dilatometry testing and the measured preliminary results are shown

Listeners as co-narrators.

Bavelas, J B; Coates, L; Johnson, T

2000-12-01

A collaborative theory of narrative story-telling was tested in two experiments that examined what listeners do and their effect on the narrator. In 63 unacquainted dyads (81 women and 45 men), a narrator told his or her own close-call story. The listeners made 2 different kinds of listener responses: Generic responses included nodding and vocalizations such as "mhm." Specific responses, such as wincing or exclaiming, were tightly connected to (and served to illustrate) what the narrator was saying at the moment. In experimental conditions that distracted listeners from the narrative content, listeners made fewer responses, especially specific ones, and the narrators also told their stories significantly less well, particularly at what should have been the dramatic ending. Thus, listeners were co-narrators both through their own specific responses, which helped illustrate the story, and in their apparent effect on the narrator's performance. The results demonstrate the importance of moment-by-moment collaboration in face-to-face dialogue.

Full Text Available Since the advent of the Global War on Terror, the world has witnessed the continuation of terrorist activity under the banner of Salafi Jihad. With military action proving insufficient to defeat the propagators of the ideology, attention has turned to the ideology itself. Understanding the narratives that constitute this ideology and the systems in place that help propagate it is crucial to defeating it. Analysis brings to light elements that arguably constitute a Jihadist master narrative as well as support structures that help perpetuate key underlying messages of this master narrative. Successful counter-narratives should focus on rolling back and containing Jihadist narratives whilst simultaneously highlighting the values and attitudes of democratic, free societies

Mellis, Alexandra M; Snider, Sarah E; Bickel, Warren K

2018-04-01

Reading experimenter-provided narratives of negative income shock has been previously demonstrated to increase impulsivity, as measured by discounting of delayed rewards. We hypothesized that writing these narratives would potentiate their effects of negative income shock on decision-making more than simply reading them. In the current study, 193 cigarette-smoking individuals from Amazon Mechanical Turk were assigned to either read an experimenter-provided narrative or self-generate a narrative describing either the negative income shock of job loss or a neutral condition of job transfer. Individuals then completed a task of delay discounting and measures of affective response to narratives, as well as rating various narrative qualities such as personal relevance and vividness. Consistent with past research, narratives of negative income shock increased delay discounting compared to control narratives. No significant differences existed in delay discounting after self-generating compared to reading experimenter-provided narratives. Positive affect was lower and negative affect was higher in response to narratives of job loss, but affect measures did not differ based on whether narratives were experimenter-provided or self-generated. All narratives were rated as equally realistic, but self-generated narratives (whether negative or neutral) were rated as more vivid and relevant than experimenter-provided narratives. These results indicate that the content of negative income shock narratives, regardless of source, consistently drives short-term choices.

Height perception influenced by texture gradient.

2012-01-01

Three experiments were carried out to examine whether a texture gradient influences perception of relative object height. Previous research implicated texture cues in judgments of object width, but similar influences have not been demonstrated for relative height. In this study, I evaluate a hypothesis that the projective ratio of the number of texture elements covered by the objects combined with the ratio of the retinal object heights determines percepts of relative object height. Density of texture background was varied: four density conditions ranged from no-texture to very dense texture. In experiments 1 and 2, participants judged the height of comparison bar compared to the standard bar positioned on no-texture or textured backgrounds. Results showed relative height judgments differed with texture manipulations, consistent with predictions from a hypothesised combination of the number of texture elements with retinal height (experiment 1), or partially consistent with this hypothesis (experiment 2). In experiment 2, variations in the position of a comparison object showed that comparisons located far from the horizon were judged more poorly than in other positions. In experiment 3 I examined distance perception; relative distance judgments were found to be also affected by textured backgrounds. Results are discussed in terms of Gibson's relational theory and distance calibration theory.

Historical imagination, narrative learning and nursing practice: graduate nursing students' reader-responses to a nurse's storytelling from the past.

Science.gov (United States)

Wood, Pamela J

2014-09-01

Storytelling and narrative are widely used in nurse education and the value of narrative-based curricula, such as those governed by narrative pedagogy, is well recognised. Storytelling stimulates students' imagination, a central feature of narrative learning. One form of story and imagination yet to be fully considered by educators is the historical story and historical imagination. The use of historical storytelling creates a temporal dissonance between the story and reader that stimulates readers' imagination and response, and enables them to gain rich insights which can be applied to the present. Reader-response theory can support educators when using narrative and storytelling. This article presents an analysis of graduate nursing students' reader-responses to a nurse's story from the past. This narrative learning group used their historical imagination in responding to the story and prompted and challenged each other in their interpretation and in translating their responses to their current nursing practice. The article discusses this analysis within the context of reader-response theory and its potential application to narrative-based learning in nurse education. Historical stories stimulate historical imagination and offer a different frame of reference for students' development of textual competence and for applying insights to the present.

Does narrative perspective influence readers’ perspective-taking? An empirical study on free indirect discourse, psycho-narration and first-person narration

Full Text Available It is often assumed that narrating a story from the protagonist’s perspective increases the readers’ inclination to take over this perspective. In a questionnaire study, we examined to which degree different textual modes of narration (a increase the degree to which the reader can generally relate to the protagonist (what we will call 'relatedness', (b make the reader prone to imagine the scene from the 'spatial point-of-view 'of the protagonist, and (c enhance the psychological perspective-taking of the reader, measured as 'identification 'with the protagonist. We employed two different types of texts—one literary and one non-literary—and tested them in four different modes of narration: free indirect discourse, psycho-narration, first-person narration and external focalization. In terms of the 'relatedness 'between the reader and protagonist and 'spatial perspective-taking 'the largest differences (descriptively occurred between external focalization and psycho-narration ('p'& .05 for 'relatedness', 'p'& .05 for 'spatial perspective-taking' and between external focalization and first-person narration ('p'& .05 for 'relatedness', for 'spatial perspective-taking p'& .1. 'Identification', measured with items from a questionnaire on reading experience (Appel et al. 2002, was highest for first-person narration. Here, the difference between first-person narration and external focalization turned out significant only after including dispositional empathy, thematic interest for the text and attention during reading as covariates. Results for the other two perspective-taking measures were unaffected by the inclusion of the same covariates. In conclusion, our data show that first-person and psycho-narration increased the tendency to take over the perspective of the protagonist, but FID did not.   This article is part of the special collection: Perspective Taking

of them is visual function and the other is word's phonetic capacity. The advantage that a poet can take from word's sound and form of writing to increase the dramatic richness of Ghazal in the story is by no means available.   Differences between narrative Ghazal and cinematic narrative   1- From the viewpoint of power of play, perhaps the major advantage the literature has over films is that a poem does not need any facilities except words to make up atmosphere and design the scene. This advantage makes poetry capable to image surreal spaces that film can not show .   2- In Ghazal, just the special signs that poet wanted is conveyed to the audience namely the author's control is more. So whenever he wants, makes the audience to focus his attention on the text or, on the contrary, divert attention away from.   Similarities between narrative Ghazal and cinematic narrative   1- Sometimes, sense and experience that the sequence of short words and phrases of Ghazal suggest to audience is the same as experience the serial of film shots convey.   2- The reader of story - even a short story– has opportunity as well as possibility to read and review each part of the story he prefers , but the movie spectator does not . Considering this, Ghazal is closer to cinema than story. Because, Ghazal is a poem to be read rather than listened , and due to the brevity prevailing over the space of poetry and Ghazal's structural limitations, poet has little opportunity to convey a sense and to present an artistic experience .   3-Today poetry uses the pattern of stanza in its formal system , like plan and shot employed in cinema. This more than verse and hemistich shows temporal and spatial distances , events and sections in the vertical axis of poetry. Such a way that each stanza expresses one temporal and spatial feature of the detached narration , whereas the sections and components of ancient poetry in the lines of verses is cluttered and the process and movement of poem are

Full Text Available This article describes the methodology and the outcomes of an empirical study of conflict narratives. The narratological analysis deployed narratological catego­ries in the structuralist tradition based on Genette and was conducted with the help of the text annotation tool CATMA. The analysis aimed at covering as many narratological phenomena as possible by establishing 14 fields of narrato­logical phenomena that were annotated in a corpus of 39 factual narratives about situations at the workplace with and without conflicts. The evaluation of approximately 28,000 annotations brought to light a series of interrelations be­tween narratological phenomena and the presence or absence of conflicts in the narratives. Additionally, this approach led to the identification of some over­sights of narrative theory by detecting hitherto unnoticed interrelations among narratological concepts.

Quantifying narrative ability in autism spectrum disorder: a computational linguistic analysis of narrative coherence.

Autism is a neurodevelopmental disorder characterized by serious difficulties with the social use of language, along with impaired social functioning and ritualistic/repetitive behaviors (American Psychiatric Association in Diagnostic and statistical manual of mental disorders: DSM-5, 5th edn. American Psychiatric Association, Arlington, 2013). While substantial heterogeneity exists in symptom expression, impairments in language discourse skills, including narrative (or storytelling), are universally observed in autism (Tager-Flusberg et al. in Handbook on autism and pervasive developmental disorders, 3rd edn. Wiley, New York, pp 335-364, 2005). This study applied a computational linguistic tool, Latent Semantic Analysis (LSA), to objectively characterize narrative performance in high-functioning individuals with autism and typically-developing controls, across two different narrative contexts that differ in the interpersonal and cognitive demands placed on the narrator. Results indicated that high-functioning individuals with autism produced narratives comparable in semantic content to those produced by controls when narrating from a picture book, but produced narratives diminished in semantic quality in a more demanding narrative recall task. This pattern is similar to that detected from analyses of hand-coded picture book narratives in prior research, and extends findings to an additional narrative context that proves particularly challenging for individuals with autism. Results are discussed in terms of the utility of LSA as a quantitative, objective, and efficient measure of narrative ability.

Are specific emotions narrated differently?

Science.gov (United States)

Habermas, Tilmann; Meier, Michaela; Mukhtar, Barbara

2009-12-01

Two studies test the assertion that anger, sadness, fear, pride, and happiness are typically narrated in different ways. Everyday events eliciting these 5 emotions were narrated by young women (Study 1) and 5- and 8-year-old girls (Study 2). Negative narratives were expected to engender more effort to process the event, be longer, more grammatically complex, more often have a complication section, and use more specific emotion labels than global evaluations. Narratives of Hogan's (2003) juncture emotions anger and fear were expected to focus more on action and to contain more core narrative sections of orientation, complication, and resolution than narratives of the outcome emotions sadness and happiness. Hypotheses were confirmed for adults except for syntactic complexity, whereas children showed only some of these differences. Hogan's theory that juncture emotions are restricted to the complication section was not confirmed. Finally, in adults, indirect speech was more frequent in anger narratives and internal monologue in fear narratives. It is concluded that different emotions should be studied in how they are narrated, and that narratives should be analyzed according to qualitatively different emotions.

Full Text Available Oat it is known as a cereal which provides numerous health benefits due to its composition. Likewise, hemp, flax and olive oils are rich in compounds required for the wellness maintenance and in prevention and treatment of various diseases. Thanks to advances of last decades in the food industry, it can be said that the rheological measurements have become indispensable in order to obtain a quality product. The aim of this work was to develop and optimize a technology for obtaining  unfermented dough, respectively, to obtain oat based unleavened bread. The characterization of the final product from a sensorial point of view was performed, analysis very important for assessing the consumers acceptance. In the meantime the texture properties of all samples were instrumentally determined. Textural profile showed that samples containing higher percent of oil content had a lower hardness than those with reduced percent of oil. The most appreciated unleavened oat bread was dried at 150˚C and had a low content of oil.

Texture memory and strain-texture mapping in a NiTi shape memory alloy

Ye, B.; Majumdar, B. S.; Dutta, I.

2007-01-01

The authors report on the near-reversible strain hysteresis during thermal cycling of a polycrystalline NiTi shape memory alloy at a constant stress that is below the yield strength of the martensite. In situ neutron diffraction experiments are used to demonstrate that the strain hysteresis occurs due to a texture memory effect, where the martensite develops a texture when it is cooled under load from the austenite phase and is thereafter ''remembered.'' Further, the authors quantitatively relate the texture to the strain by developing a calculated strain-texture map or pole figure for the martensite phase, and indicate its applicability in other martensitic transformations

What are narratives good for?

Beatty, John

Narratives may be easy to come by, but not everything is worth narrating. What merits a narrative? Here, I follow the lead of narratologists and literary theorists, and focus on one particular proposal concerning the elements of a story that make it narrative-worthy. These elements correspond to features of the natural world addressed by the historical sciences, where narratives figure so prominently. What matters is contingency. Narratives are especially good for representing contingency and accounting for contingent outcomes. This will be squared with a common view that narratives leave no room for chance. On the contrary, I will argue, tracing one path through a maze of alternative possibilities, and alluding to those possibilities along the way, is what a narrative does particularly well.

Surimi-based seafood products are widely accepted and enjoyed worldwide. The US consumption increased in 1980s; however, it leveled thereafter. Food products nutrified with ω-3 polyunsaturated fatty acids (PUFAs) are in increasing demand due to demonstrated health benefits. Currently, surimi seafood is not nutrified with ω-3 PUFAs. In the present study, surimi seafood was nutritionally-enhanced with ω-3 PUFAs-rich oils (flaxseed, algae, menhaden, krill, and blend). The objectives were (1) chemical characterization of FA composition and oxidation, and (2) determination of physicochemical properties (colour and texture) of the nutritionally-enhanced surimi seafood. Oil addition resulted in increased (P<0.05) concentration of total ω-3 FAs in surimi seafood; however, the concentration of α-linolenic (ALA, 18:3ω-3), eicosapentaenoic (EPA, 20:5ω-3) and docosahexaenoic (DHA, 22:6ω-3) acids depended on which oil was added. Although the ω-3 PUFAs nutrification resulted in increased (P<0.05) susceptibility of surimi seafood to lipid oxidation, it was within ranges acceptable to consumers. Texture analysis (texture profile analysis, Kramer shear and torsion test) showed that ω-3 PUFAs nutrification did not affect texture. Colour properties of ω-3 PUFAs nutrified surimi seafood were generally improved except when krill oil or blend was added. This study demonstrates that nutritional value of surimi seafood can be enhanced with concurrent improvement of colour and without affecting texture. Copyright © 2011 Elsevier Ltd.

Efficient rolling texture predictions and texture-sensitive thermomechanical properties of α-uranium foils

Science.gov (United States)

Steiner, Matthew A.; Klein, Robert W.; Calhoun, Christopher A.; Knezevic, Marko; Garlea, Elena; Agnew, Sean R.

2017-11-01

Finite element (FE) analysis was used to simulate the strain history of an α-uranium foil during cold straight-rolling, with the sheet modeled as an isotropic elastoplastic continuum. The resulting strain history was then used as input for a viscoplastic self-consistent (VPSC) polycrystal plasticity model to simulate crystallographic texture evolution. Mid-plane textures predicted via the combined FE→VPSC approach show alignment of the (010) poles along the rolling direction (RD), and the (001) poles along the normal direction (ND) with a symmetric splitting along RD. The surface texture is similar to that of the mid-plane, but with a shear-induced asymmetry that favors one of the RD split features of the (001) pole figure. Both the mid-plane and surface textures predicted by the FE→VPSC approach agree with published experimental results for cold straight-rolled α-uranium plates, as well as predictions made by a more computationally intensive full-field crystal plasticity based finite element model. α-uranium foils produced by cold-rolling must typically undergo a recrystallization anneal to restore ductility prior to their final application, resulting in significant texture evolution from the cold-rolled plate deformation texture. Using the texture measured from a foil in the final recrystallized state, coefficients of thermal expansion and the elastic stiffness tensors were calculated using a thermo-elastic self-consistent model, and the anisotropic yield loci and flow curves along the RD, TD, and ND were predicted using the VPSC code.

Perceptual asymmetry in texture perception.

A fundamental property of human visual perception is our ability to distinguish between textures. A concerted effort has been made to account for texture segregation in terms of linear spatial filter models and their nonlinear extensions. However, for certain texture pairs the ease of discrimination changes when the role of figure and ground are reversed. This asymmetry poses a problem for both linear and nonlinear models.

During corrosion of zirconium alloys a highly textured oxide is formed, the degree of this preferred orientation has previously been shown to be an important factor in determining the corrosion behaviour of these alloys. Two distinct experiments were designed in order to investigate the origin of this oxide texture development on two commercial alloys. Firstly, sheet samples of Zircaloy-4 were oxidised between 500 and 800 °C in air. The resulting monoclinic oxide texture strength was observed to decrease with increasing oxidation temperature. In a second experiment, orthogonal faces of Low Tin ZIRLO{sub ™} were oxidised in 360 °C water, providing different substrate textures but identical microstructures. The substrate texture was observed to have a negligible effect on the corrosion performance whilst the major orientation of both oxide phases was found to be independent of substrate orientation. It is concluded that the main driving force for oxide texture development in single-phase zirconium alloys is the compressive stress caused by the Zr−ZrO{sub 2} transformation. - Highlights: • Substrate orientation does not significantly affect oxide texture development. • Corrosion performance is independent of substrate texture. • Monoclinic oxide texture strength decreases with increasing oxidation temperature. • The main driving force for texture development is the oxidation-induced stress.

A fundamental property of human visual perception is our ability to distinguish between textures. A concerted effort has been made to account for texture segregation in terms of linear spatial filter models and their nonlinear extensions. However, for certain texture pairs the ease of discrimination changes when the role of figure and ground are reversed. This asymmetry poses a problem for both linear and nonlinear models. We have isolated a property of texture perception that can account for this asymmetry in discrimination: subjective closure. This property, which is also responsible for visual illusions, appears to be explainable by early visual processes alone. Our results force a reexamination of the process of human texture segregation and of some recent models that were introduced to explain it.

Gypsy stories: Narrative as a teaching stratagem

2010-01-01

Full Text Available This paper discusses the performance of narratives as adaptive cultural beha­viors among Gypsies in Mačva county, western Serbia. Storytelling is a universal activity and may well be oldest of the arts. It has always provided a vehicle for the expression of ideas, particularly in societies relying on oral tradition. Gypsies are present in Serbia since the Middle Ages, living within a larger Serbian culture as a minority group. Mačva, an agriculturally rich county in western Serbia, is a place where local Gypsy traditions are still alive and which help distinguish between Gypsy subgroups and the larger Serbian society. The stories analyzed are part of a collec­tion made from several different Gypsy groups exhibiting varying degrees of influence from Serbian culture. Gypsies in Serbia have no written literature, but possess a rich and varied storytelling tradition delivered by word of mouth through the generations. Their stories bear testimony to the evolutionarily important mecha­nisms employed by Gypsies to make their way in the world. Gypsy stories concern many aspects of the relationship between themselves and other social groups, both in the past and the present. At the same time, the stories deal with universal adaptive problems, such as origin/ethnicity, kinship and mate acquisition. By applying the concepts and folk knowledge from their own culture, Gypsies have managed to provide for themselves the guidelines to overcome these problems within a par­ticular environment. Thus it is that these stories reflect both human universals and cultural peculiarities - by utilization of localized cultural solutions to adaptive problems. The success Gypsies have achieved in surviving harassment, and their ability to sustain themselves and their cultures despite social rejection can be attributed, in part, to the power of the traditional stories to influence the behavior of those who hear them. For the Gypsies, telling and listening to the stories

Gravitational effects of global textures

International Nuclear Information System (INIS)

Noetzold, D.

1990-03-01

A solution for the dynamics of global textures is obtained. Their gravitational field during the collapse and the subsequent evolution is found to be given solely by a space-time dependent ''deficit solid angle.'' The frequency shift of photons traversing this gravitational field is calculated. The space-time dependent texture metric locally contracts the volume of three-space and thereby induces overdensities in homogeneous matter distributions. There are no gravitational forces unless matter has a nonzero angular momentum with respect to the texture origin which would be the case for moving textures

Cinematic narratives of Sonderkommando: Son of saul or narrating the victim, perpetrator, trauma and death

Directory of Open Access Journals (Sweden)

Daković Nevena

2016-01-01

Full Text Available The aim of this paper is to map out - by analysing the film Son of Saul, but also by its comparison with two other films dealing with the topic, Himmelkommando and The Grey Zone, the narrative mechanism that satisfies the complex ethical and aesthetical demands imposed by the theme of Sonderkommando as the particular episode of the Holocaust. The key element of the narrative structure is the construction of the Levi’s “dead and drowned” witness who “resurrected” through the narrative intervention becomes the only reliable and credible narrator of the historical trauma. The prerequisite for his emergence is the narration and representation of the death which makes but also solves the traumatised - understood as multiple, fragmented, opposed - identities of the members of the special squad. Their entangled identity involves the simultaneous presence of a victim, perpetrator, witness and the authentic narrator of the trauma of the death camp. The death of the perpetrator is the condition sina qua non for the emergence of the figure of the victim-witness narrator but also for making of narrative which overcomes the initial trauma of the Holocaust. The detailed analysis of the film Son of Saul confirms and identifies these narratives as the modernist narration of the post-traumatic film.

2011-02-15

A combination of electron backscatter diffraction and energy-dispersive X-ray spectroscopy has been used to identify the crystal structure and composition of all the phases present in commercially available NdFeB sintered magnets and to map their spatial distribution. The Nd{sub 2}Fe{sub 14}B and NdO grains were shown to have low defect densities. The fcc Nd-rich and Nd{sub 2}O{sub 3} grains had intra-grain misorientation angles of up to 14{sup o}, which was shown to be due to defects. Large numbers ({approx}100) of data points for each phase were used to study texture in the NdO, Nd{sub 2}O{sub 3} and Nd{sub 2}Fe{sub 14}B phases. The Nd{sub 2}Fe{sub 14}B grains exhibited a <0 0 1> fibre texture. The Nd oxide phases showed no strong texture, which implied that no strongly preferred orientation relationships between those phases and Nd{sub 2}Fe{sub 14}B exist. The result was shown to be valid for optimally annealed samples exhibiting high coercivity and as-sintered samples exhibiting low coercivity.

Annealing texture of rolled nickel alloys

International Nuclear Information System (INIS)

Meshchaninov, I.V.; Khayutin, S.G.

1976-01-01

A texture of pure nickel and binary alloys after the 95% rolling and annealing has been studied. Insoluble additives (Mg, Zr) slacken the cubic texture in nickel and neral slackening of the texture (Zr). In the case of alloying with silicium (up to 2%) the texture practically coinsides with that of a technical-grade nickel. The remaining soluble additives either do not change the texture of pure nickel (C, Nb) or enhance the sharpness and intensity of the cubic compontnt (Al, Cu, Mn, Cr, Mo, W, Co -at their content 0.5 to 2.0%). A model is proposed by which variation of the annealing texture upon alloying is caused by dissimilar effect of the alloying elements on the mobility of high- and low-angle grain boundaries

Development of personal narratives as a mediator of the impact of deficits in social cognition and social withdrawal on negative symptoms in schizophrenia.

2012-04-01

Although negative symptoms are a barrier to recovery from schizophrenia, little is understood about the psychological processes that reinforce and sustain them. To explore this issue, this study used structural equation modeling to test whether the impact of social withdrawal and emotion recognition deficits upon negative symptoms is mediated by the richness or poverty of personal narratives. The participants were 99 adults with schizophrenia spectrum disorders. Social cognition was assessed using the Bell-Lysaker Emotional Recognition Task; social withdrawal, using the Quality of Life Scale; narrative coherence, using the Scale To Assess Narrative Development; and negative symptoms, using the Positive and Negative Syndrome Scale. The findings reveal that although social cognition deficits and social withdrawal are significantly associated with negative symptom severity, these relationships become nonsignificant when personal narrative integrity is examined as a mediating factor. These results indicate that the development of personal narratives may be directly linked to the severity of negative symptoms; this construct may be a useful target for future interventions.

Politics of love: narrative structures, intertextuality and social agency in the narratives of parents with disabled children.

Hanisch, Halvor

2013-11-01

Recent research has highlighted how parental narratives can be important in the resistance against disabling processes. This article contains analyses of enabling language in narratives published by Scandinavian disability rights organizations. First, drawing on the work of Fisher and Goodley, I point out that the material constitute a threefold: normality narratives, resistance narratives, and narratives that demonstrate an appreciation of the present and the child's individual alterity. Second, I demonstrate that the last narrative draws on Romanticism rather than linguistic resources from disability culture. Third, I show that these narratives are hyperboles - texts that strengthen and emphasise the valuation to the point where the narrative structure transcends narrative consistency. Fourth, drawing on the work of Kristeva, I argue that this form of narration constitutes an intimate politics of love. © 2013 The Author.

Šugár, Peter; Šugárová, Jana; Frnčík, Martin

2016-05-01

In this experimental investigation the laser surface texturing of tool steel of type 90MnCrV8 has been conducted. The 5-axis highly dynamic laser precision machining centre Lasertec 80 Shape equipped with the nano-second pulsed ytterbium fibre laser and CNC system Siemens 840 D was used. The planar and spherical surfaces first prepared by turning have been textured. The regular array of spherical and ellipsoidal dimples with a different dimensions and different surface density has been created. Laser surface texturing has been realized under different combinations of process parameters: pulse frequency, pulse energy and laser beam scanning speed. The morphological characterization of ablated surfaces has been performed using scanning electron microscopy (SEM) technique. The results show limited possibility of ns pulse fibre laser application to generate different surface structures for tribological modification of metallic materials. These structures were obtained by varying the processing conditions between surface ablation, to surface remelting. In all cases the areas of molten material and re-cast layers were observed on the bottom and walls of the dimples. Beside the influence of laser beam parameters on the machined surface quality during laser machining of regular hemispherical and elipsoidal dimple texture on parabolic and hemispherical surfaces has been studied.

Why Narrating Changes Memory: A Contribution to an Integrative Model of Memory and Narrative Processes.

Science.gov (United States)

Smorti, Andrea; Fioretti, Chiara

2016-06-01

This paper aims to reflect on the relation between autobiographical memory (ME) and autobiographical narrative (NA), examining studies on the effects of narrating on the narrator and showing how studying these relations can make more comprehensible both memory's and narrating's way of working. Studies that address explicitly on ME and NA are scarce and touch this issue indirectly. Authors consider different trends of studies of ME and NA: congruency vs incongruency hypotheses on retrieving, the way of organizing memories according to gist or verbatim format and their role in organizing positive and negative emotional experiences, the social roots of ME and NA, the rules of conversation based on narrating. Analysis of investigations leads the Authors to point out three basic results of their research. Firstly, NA transforms ME because it narrativizes memories according to a narrative format. This means that memories, when are narrated, are transformed in stories (verbal language) and socialised. Secondly, the narrativization process is determined by the act of telling something within a communicative situation. Thus, relational situation of narrating act, by modifying the story, modifies also memories. The Authors propose the RE.NA.ME model (RElation, NArration, MEmory) to understand and study ME and NA. Finally, this study claims that ME and NA refer to two different types of processes having a wide area of overlapping. This is due to common social, developmental and cultural roots that make NA to include part of ME (narrative of memory) and ME to include part of NA (memory of personal events that have been narrated).

Forensic historiography: narratives and science.

Science.gov (United States)

Drukteinis, Albert M

2014-01-01

Psychiatrists function, in part, as historians who rely on patient narratives to help them understand presenting mental disorders and explain their causes. Forensic psychiatrists have been skeptical of using narratives, raising concerns about their lack of objectivity and potential for bias. They also have criticized narratives as being more performative than scientific. Recent authors, however, have pointed out that narratives may be helpful in forming forensic opinions and supporting oral testimony, while stressing that their use must be consistent with the ethics espoused by forensic psychiatry. This article reviews the role of narratives in understanding human events and the ubiquitous presence of narratives in the judicial process. It delves into the inescapability of using explicit or implicit narratives in the course of forensic practice, as well as how they may be meaningfully incorporated into evaluations and find expression alongside scientific principles. © 2014 American Academy of Psychiatry and the Law.

Narrative research in psychotherapy: a critical review.

Science.gov (United States)

Avdi, Evrinomy; Georgaca, Eugenie

2007-09-01

This paper is a review of studies which utilise the notion of narrative to analyse psychotherapy. Its purpose is to systematically present this diverse field of research, to highlight common themes and divergences between different strands and to further the development and integration of narrative research in psychotherapy. The paper reviews studies which employ an applied textual analysis of narratives produced in the context of psychotherapy. Criteria for inclusion of studies are, firstly, the analysis of therapeutic and therapy-related texts and, secondly, the adoption of a narrative psychological perspective. The studies were examined on the basis of the notion of narrative they employ and the aspects of client narratives they focus on, and were grouped accordingly in the review. The majority of the studies reviewed assume a constructivist approach to narrative, adopt a representational view of language, focus primarily on client micro-narratives and relate to cognitive-constructivist and process-experiential psychotherapeutic approaches. A smaller group of studies assume a social constructionist approach to narrative and a functional view of language, focus on micro-narratives, highlight the interactional and wider social aspects of narrative and relate to postmodern trends in psychotherapy. The range of conceptualisations of narrative in the studies reviewed, from a representational psychological view to a constructionist social view, reflects tensions within narrative psychology itself. Moreover, two trends can be discerned in the field reviewed, narrative analysis of therapy, which draws from narrative theory and utilises the analytic approaches of narrative research to study psychotherapy, and analyses of narrative in therapy, which study client narratives using non-narrative qualitative methods. Finally, the paper highlights the need for integration of this diverse field of research and urges for the development of narrative studies of psychotherapy

Full Text Available This thematic issue addresses how strategic narratives affect international order. Strategic narratives are conceived of as stories with a political purpose or narratives used by political actors to affect the behavior of others. The articles in this issue address two significant areas important to the study of international relations: how strategic narratives support or undermine alliances, and how they affect norm formation and contestation. Within a post-Cold War world and in the midst of a changing media environment, strategic narratives affect how the world and its complex issues are understood. This special issue speaks to the difficulties associated with creating creative and committed international cooperation by noting how strategic narratives are working to shape the Post-Cold War international context.

is profoundly saturated by an alienness regarding the person’s own affects and responses. However, the balance of familiarity and alienness is not static, but can be cultivated through e.g. psychotherapy. Following this line of thought, I present the idea that narrativising experiences can play an important...... role in processes of appropriating such embodied self-alienness. Importantly, the notion of narrative used is that of a scalar conception of narrativity as a variable quality of experience that comes in degrees. From this perspective, narrative appropriation is a process of gradually attributing...

Not all stories of professional identity formation are equal: An analysis of formation narratives of highly humanistic physicians.

Science.gov (United States)

Branch, William T; Frankel, Richard

2016-08-01

We sought to identify and define "highly humanistic" formation narratives, and understand how these events described, together with a reflective learning process, the professional development of physicians in a longitudinal faculty development program. Qualitative analysis of twenty highly humanistic appreciative inquiry narratives selected from a total of 124 written by faculty members at the beginning and end of an eighteen month program at eight medical schools. [9,10] We employed the immersion/crystallization method of Borkan [20] to capture the rich meanings and emotional depth of the twenty narratives. Highly humanistic formation narratives described emotionally charged events in which the faculty writers provided humanistic care that went beyond what they had previously thought themselves capable of; benefited the patient, family or faculty member to a major extent; and reaffirmed or strengthened their professional values. Highly humanistic formation narratives were clustered at the end of our eighteen month curriculum. Participation in faculty development for humanism may have increased the numbers of highly humanistic events by sensitizing and motivating faculty members to meet their patients' emotional needs. Our paper describes a process whereby faculty members may achieve growth in their capacities to meet patients' needs. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Highly radioactive cesium-rich microparticles (CsMPs) released from the Fukushima Daiichi Nuclear Power Plant (FDNPP) provide nano-scale chemical fingerprints of the 2011 tragedy. U, Cs, Ba, Rb, K, and Ca isotopic ratios were determined on three CsMPs (3.79-780 Bq) collected within ~10 km from the FDNPP to determine the CsMPs' origin and mechanism of formation. Apart from crystalline Fe-pollucite, CsFeSi 2 O 6  · nH 2 O, CsMPs are comprised mainly of Zn-Fe-oxide nanoparticles in a SiO 2 glass matrix (up to ~30 wt% of Cs and ~1 wt% of U mainly associated with Zn-Fe-oxide). The 235 U/ 238 U values in two CsMPs: 0.030 (±0.005) and 0.029 (±0.003), are consistent with that of enriched nuclear fuel. The values are higher than the average burnup estimated by the ORIGEN code and lower than non-irradiated fuel, suggesting non-uniform volatilization of U from melted fuels with different levels of burnup, followed by sorption onto Zn-Fe-oxides. The nano-scale texture and isotopic analyses provide a partial record of the chemical reactions that occurred in the fuel during meltdown. Also, the CsMPs were an important medium of transport for the released radionuclides in a respirable form.

The ideal filler for aesthetic surgery is inexpensive and easy to obtain, natural in appearance and texture, immunologically compatible, and long lasting without risk of infection. By most metrics, autologous fat grafts meet these criteria perfectly. Although facial fat grafting is now a commonly accepted surgical procedure, there has been a wave of activity applying stem cells and platelet-rich plasma (PRP) therapies to aesthetic practice. This article addresses technical considerations in the use of autologous fat transfer for facial rejuvenation, and also explores the current evidence for these stem cell and PRP therapies in aesthetic practice.

Science.gov (United States)

Lawton, W. M.; Lee, M.

1984-01-01

A general theory of image texture models is proposed and its applicability to the problem of scene segmentation using texture classification is discussed. An algorithm, based on half-plane autoregressive filtering, which optimally utilizes second order statistics to discriminate between texture classes represented by arbitrary wide sense stationary random fields is described. Empirical results of applying this algorithm to natural and sysnthesized scenes are presented and future research is outlined.

CRUMB TEXTURE OF SPELT BREAD

Full Text Available Abstract The bread quality is considerably dependent on the texture characteristic of bread crumb. Crumb texture is an important quality indicator, as consumer prefer different bread taste. Texture analysis is primarily concerned with the evaluation of mechanical characteristics where a material is subjected to a controlled force from which a deformation curve of its response is generated. It is an objective physical examination of baked products and gives direct information on the product quality, oppositely to dough rheology tests what inform on the baking suitability of the flour, as raw material. This is why the texture analysis is one of the most helpful analytical methods of the product development. In the framework of our research during the years 2008 – 2009 were analyzed selected indicators for bread texture quality of five Triticum spelta L. varieties – Altgold, Oberkulmer Rotkorn, Ostro, Rubiota and Franckenkorn grown in an ecological system. The bread texture quality was evaluated on texture analyzer TA.XT Plus (Stable Micro Systems, Surrey, UK, following the AACC (74-09 standard method and expressed as crumb firmness (N, stiffness (N.mm-1 and relative elasticity (%. Our research proved that all selected indicators were significantly influenced by the year of growing and variety. The most soft bread was achieved in Rubiota, whereas bread crumb samples from Franckenkorn and Altgold were the most firm and stiff. Correlation analysis showed strong negative correlation between relative elasticity and bread crumb firmness as well as bread stiffness (-0.81++, -0.78++. The spelt grain can be a good source for making bread flour, but is closely dependent on choice of spelt variety. The spelt wheat bread crumb texture need further investigation as it can be a reliable quality parameter.

Narrative Fortresses: Crisis Narratives and Conflict in the Conservation of Mount Gorongosa, Mozambique

Directory of Open Access Journals (Sweden)

Christy Schuetze

2015-01-01

Full Text Available A single narrative about the Gorongosa Restoration Project (GRP in Mozambique circulates widely in the popular media. This story characterises the project as an innovative intervention into an ecological crisis situation. The narrative hails the project′s aim to use profits from tourism to address the goals of both human development and conservation of biodiversity, and portrays the park project as widely embraced by long-term residents. This representation helps the project attract broad acclaim, donor funding, and socially conscious visitors, yet it obscures the early emergence of unified opposition to the project′s interventions among long-term residents of Gorongosa Mountain. This article draws on ethnographic research conducted on Gorongosa Mountain between 2006 and 2008 to examine the project′s early activities there. I examine two crisis narratives that led to entrenched conflict between park-based actors and mountain residents. Focusing on the emergence and solidification of divergent narratives-narrative fortresses-about the extension of the park′s activities to Gorongosa Mountain offers insight into the powerful role of crisis narratives in producing and maintaining conflict, leading to outcomes counter to the desires of conservationists. Ultimately, the article points to ways in which narratives of environmental crisis work against aspirations of partnership and collaboration with resident populations in conservation and development schemes.

Symmetry realization of texture zeros

International Nuclear Information System (INIS)

Grimus, W.; Joshipura, A.S.; Lavoura, L.; Tanimoto, M.

2004-01-01

We show that it is possible to enforce texture zeros in arbitrary entries of the fermion mass matrices by means of Abelian symmetries; in this way, many popular mass-matrix textures find a symmetry justification. We propose two alternative methods which allow one to place zeros in any number of elements of the mass matrices that one wants. They are applicable simultaneously in the quark and lepton sectors. They are also applicable in grand unified theories. The number of scalar fields required by our methods may be large; still, in many interesting cases this number can be reduced considerably. The larger the desired number of texture zeros is, the simpler are the models which reproduce the texture. (orig.)

Texture and anisotropy in ferroelectric lead metaniobate

Science.gov (United States)

Iverson, Benjamin John

Ferroelectric lead metaniobate, PbNb2O6, is a piezoelectric ceramic typically used because of its elevated Curie temperature and anisotropic properties. However, the piezoelectric constant, d33, is relatively low in randomly oriented ceramics when compared to other ferroelectrics. Crystallographic texturing is often employed to increase the piezoelectric constant because the spontaneous polarization axes of grains are better aligned. In this research, crystallographic textures induced through tape casting are distinguished from textures induced through electrical poling. Texture is described using multiple quantitative approaches utilizing X-ray and neutron time-of-flight diffraction. Tape casting lead metaniobate with an inclusion of acicular template particles induces an orthotropic texture distribution. Templated grain growth from seed particles oriented during casting results in anisotropic grain structures. The degree of preferred orientation is directly linked to the shear behavior of the tape cast slurry. Increases in template concentration, slurry viscosity, and casting velocity lead to larger textures by inducing more particle orientation in the tape casting plane. The maximum 010 texture distributions were two and a half multiples of a random distribution. Ferroelectric texture was induced by electrical poling. Electric poling increases the volume of material oriented with the spontaneous polarization direction in the material. Samples with an initial paraelectric texture exhibit a greater change in the domain volume fraction during electrical poling than randomly oriented ceramics. In tape cast samples, the resulting piezoelectric response is proportional to the 010 texture present prior to poling. This results in property anisotropy dependent on initial texture. Piezoelectric properties measured on the most textured ceramics were similar to those obtained with a commercial standard.

Theoretical perspectives on narrative inquiry.

Narrative inquiry is gaining momentum in the field of nursing. As a research approach it does not have any single heritage of methodology and its practitioners draw upon diverse sources of influence. Central to all narrative inquiry however, is attention to the potential of stories to give meaning to people's lives, and the treatment of data as stories. This is the first of two papers on the topic and addresses the theoretical influences upon a particular narrative inquiry into nursing scholars and scholarship. The second paper, Conducting a narrative analysis, describes the actual narrative analysis as it was conducted in this same study. Together, the papers provide sufficient detail for others wishing to pursue a similar approach to do so, or to develop the ideas and procedures according to their own way of thinking. Within this first theoretical paper, perspectives from Jerome Bruner (1987) and Wade Roof (1993) are outlined. These relate especially to the notion of stories as 'imaginative constructions' and as 'cultural narratives' and as such, highlight the profound importance of stories as being individually and culturally meaningful. As well, perspectives on narrative inquiry from nursing literature are highlighted. Narrative inquiry in this instance lies within the broader context of phenomenology.

There is a rich amount of quantitative information in spectral datasets generated from dual-energy CT (DECT). In this study, we compare the performance of texture analysis performed on multi-energy datasets to that of virtual monochromatic images (VMIs) at 65 keV only, using classification of the two most common benign parotid neoplasms as a testing paradigm. Forty-two patients with pathologically proven Warthin tumour (n = 25) or pleomorphic adenoma (n = 17) were evaluated. Texture analysis was performed on VMIs ranging from 40 to 140 keV in 5-keV increments (multi-energy analysis) or 65-keV VMIs only, which is typically considered equivalent to single-energy CT. Random forest (RF) models were constructed for outcome prediction using separate randomly selected training and testing sets or the entire patient set. Using multi-energy texture analysis, tumour classification in the independent testing set had accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of 92%, 86%, 100%, 100%, and 83%, compared to 75%, 57%, 100%, 100%, and 63%, respectively, for single-energy analysis. Multi-energy texture analysis demonstrates superior performance compared to single-energy texture analysis of VMIs at 65 keV for classification of benign parotid tumours. • We present and validate a paradigm for texture analysis of DECT scans. • Multi-energy dataset texture analysis is superior to single-energy dataset texture analysis. • DECT texture analysis has high accura\\cy for diagnosis of benign parotid tumours. • DECT texture analysis with machine learning can enhance non-invasive diagnostic tumour evaluation.

Composite grafts are suitable for facial reconstruction because of good color matching, low donor-site morbidity, acceptable texture, and easy surgical techniques. However, their use is limited to small defects and by unpredictable survival rates. As platelet-rich plasma contains large numbers of growth factors and has been widely used for tissue regeneration, this study aimed to investigate platelet-rich plasma as an adjuvant to enhance composite graft survival. Twenty New Zealand White rabbits were used, and chondrocutaneous composite grafts were applied to their ears. The grafts were then returned to their original positions after rotation to block the original circulation from the base of the graft. Each of the individual ears was assigned randomly into one of two groups: experimental (n=20; platelet-rich plasma group) or control (n=20; control group). The surrounding skin of the composite graft was injected with either 1.0 ml of platelet-rich plasma derived from autologous whole blood in the platelet-rich plasma group or normal saline in the control group. Graft survival, cutaneous blood flow, CD31-stained vessels, and vascular endothelial growth factor protein levels were examined. Twelve days after surgery, graft viability in the platelet-rich plasma group was higher than in the control group. Blood perfusion was also higher in the platelet-rich plasma group. Compared with the control group, the number of CD31 blood vessels and vascular endothelial growth factor expression levels were significantly increased in the platelet-rich plasma group. The authors' results suggest that platelet-rich plasma restores the perfusion of composite grafts by enhancing revascularization and may exert therapeutic effects on the survival of composite grafts.

TEXTURAL DESCRIPTORS FOR MULTIPHASIC ORE PARTICLES

Directory of Open Access Journals (Sweden)

Laura Pérez-Barnuevo

2012-11-01

Full Text Available Monitoring of mineral processing circuits by means of particle liberation analysis through quantitative image analysis has become a routine technique within the last decades. Usually, liberation indices are computed as weight proportions, which is not informative enough when complex texture ores are treated by flotation. In these cases, liberation has to be computed as phase surface exposed to reactants, and textural relationships between minerals have to be characterized to determine the possibility of increasing exposure. In this paper, some indices to achieve a complete texture characterization have been developed in terms of 2D phase contact and mineral surfaces exposure. Indices suggested by other authors are also compared. The response of this set of parameters against textural changes has been explored on simple synthetic textures ranging from single to multiple inclusions and single to multiple veins and their ability to discriminate between different textural features is analyzed over real mineral particles with known internal structure.

Description of textures by a structural analysis.

Science.gov (United States)

Tomita, F; Shirai, Y; Tsuji, S

1982-02-01

A structural analysis system for describing natural textures is introduced. The analyzer automatically extracts the texture elements in an input image, measures their properties, classifies them into some distinctive classes (one ``ground'' class and some ``figure'' classes), and computes the distributions of the gray level, the shape, and the placement of the texture elements in each class. These descriptions are used for classification of texture images. An analysis-by-synthesis method for evaluating texture analyzers is also presented. We propose a synthesizer which generates a texture image based on the descriptions. By comparing the reconstructed image with the original one, we can see what information is preserved and what is lost in the descriptions.

Narrating the Racialization of Space in Austin, Texas and Nashville, Tennessee

Full Text Available Narrating the Racialization of Space in Austin, Texas and Nashville, Tennessee People of color in the United States have been obligated to move through public space in particular ways, dictated by law and social custom. Narrators create cognitive maps of movement in the city shaped by racial codes of behavior. The maps change over time as law and social custom changes. The fluidity of the maps is also influenced by status, gender, class, and skin tone. This paper examines a rich body of oral narratives co-created with African Americans from 2004 to 2014 focusing on how men and women narrate their concepts of racialized space. It moves from narratives about the larger landscape — the city — to smaller, more personal public places — the sidewalk and the store — to intimate sites of contact in the public sphere. Many of the narratives describe complex flows of controlled movement dictated by racial boundaries in the context of capitalism. The narratives form an urban ethnography of the power relations inscribed on the landscape by racializing movement in space.   Narracje o urasowieniu przestrzeni w Austin (Teksas i Nashville (Tennessee Nie-Biali w Stanach Zjednoczonych byli zmuszeni do poruszania się w przestrzeni publicznej w szczególny sposób, określony przez prawo i zwyczaj społeczny.

Fernandes Davies, Vanessa; Mafra, Rafaella; Beltran, Alicia; Baranowski, Thomas; Lu, Amy Shirong

2016-04-01

This article presents the results of interviews conducted with children regarding their cognitive and affective responses toward a narrative and a non-narrative cartoon. The findings will be used to further explore the role of a narrative in motivating continued active videogame play. Twenty children (8-11 years old of mixed gender) watched two cartoons (narrative and non-narrative) and were subsequently interviewed. A thematic matrix was used to analyze the interviews. The narrative cartoon (n = 11) was only slightly preferred compared with the non-narrative one (n = 9), with little difference among the participants. The theme categories identified during the analyses were plot, characters, and suggestions. The fight scenes were mentioned by the children as a likeable aspect of the narrative cartoon. In the non-narrative cartoon, the vast majority (n = 17) liked the information about physical activity that was provided. The children enjoyed the appearance and personalities of the characters in both cartoons. A discrepancy in the data about the fight scenes (narrative cartoon) and characters (both cartoons) was found among the female participants (i.e., some girls did not like the fight and thought the characters were too aggressive). However, most of the children wanted to see more action in the story, an increase in the number of fight scenes (narrative cartoon), or more information about exercise and examples of exercises they could do (non-narrative cartoon). They also suggested adding a game to the non-narrative cartoon, including more characters, and improving the animation in both cartoons. The children preferred the narrative cartoon because of the story and the fight. Some gender differences were found, which further studies should investigate.

Vanitha, C.; Kiran Kumar, M.; Samajdar, I.; Vishvanathan, N.N.; Dey, G.K.; Tewari, R.; Srivastava, D.; Banerjee, S.

2002-01-01

In the present study, two starting materials used were as-cast Zircaloy-2 with random texture and the finished tube with relatively stronger starting texture. Specimens of the alloys were hot rolled to various strains at different temperature. The texture measurement was carried out and was represented in the form of Orientation Distribution Function which showed a sluggish texture development on high temperature deformation. In the case of as cast alloy with increase in strain at a constant deformation temperature, development in the texture was significant. Upon increasing the working temperature, rate of the overall texture development has been found to reduce. This could be due to reduced slip-twin activities, recovery or due to recrystallization. Microstructural and relative hardening studies were carried out for understanding the mechanisms of deformation texture developments at warm and hot working stages. In the case of finished tube having initially strong texture exhibited slower development in texture on warm and hot rolling. (author)

Consistency and stability of narrative coherence: An examination of personal narrative as a domain of adult personality.

Science.gov (United States)

Waters, Theodore E A; Köber, Christin; Raby, K Lee; Habermas, Tilmann; Fivush, Robyn

2018-03-02

Narrative theories of personality assume that individual differences in coherence reflect consistent and stable differences in narrative style rather than situational and event-specific differences (e.g., McAdams & McLean, 2013). However, this assumption has received only modest empirical attention. Therefore, we present two studies testing the theoretical assumption of a consistent and stable coherent narrative style. Study 1 focused on the two most traumatic and most positive life events of 224 undergraduates. These event-specific narratives were coded for three coherence dimensions: theme, context, and chronology (NaCCs; Reese et al., 2011). Study 2 focused on two life narratives told 4 years apart by 98 adults, which were coded for thematic, causal, and temporal coherence (Köber, Schmiedek, & Habermas, 2015). Confirmatory factor analysis in both studies revealed that individual differences in the coherence ratings were best explained by a model including both narrative style and event-/narration-specific latent variables. The ways in which we tell autobiographical narratives reflect a stable feature of individual differences. Further, they suggest that this stable element of personality is necessary, but not sufficient, in accounting for specific event and life narrative coherence. © 2018 Wiley Periodicals, Inc.

Texture Repairing by Unified Low Rank Optimization

Institute of Scientific and Technical Information of China (English)

Xiao Liang; Xiang Ren; Zhengdong Zhang; Yi Ma

2016-01-01

In this paper, we show how to harness both low-rank and sparse structures in regular or near-regular textures for image completion. Our method is based on a unified formulation for both random and contiguous corruption. In addition to the low rank property of texture, the algorithm also uses the sparse assumption of the natural image: because the natural image is piecewise smooth, it is sparse in certain transformed domain (such as Fourier or wavelet transform). We combine low-rank and sparsity properties of the texture image together in the proposed algorithm. Our algorithm based on convex optimization can automatically and correctly repair the global structure of a corrupted texture, even without precise information about the regions to be completed. This algorithm integrates texture rectification and repairing into one optimization problem. Through extensive simulations, we show our method can complete and repair textures corrupted by errors with both random and contiguous supports better than existing low-rank matrix recovery methods. Our method demonstrates significant advantage over local patch based texture synthesis techniques in dealing with large corruption, non-uniform texture, and large perspective deformation.

Ioannou, Maria; Canter, David; Youngs, Donna

2017-10-01

A neglected area of research within criminality has been that of the experience of the offence for the offender. The present study investigates the emotions and narrative roles that are experienced by an offender while committing a broad range of crimes and proposes a model of criminal narrative experience (CNE). Hypotheses were derived from the circumplex of emotions, Frye, narrative theory, and its link with investigative psychology. The analysis was based on 120 cases. Convicted for a variety of crimes, incarcerated criminals were interviewed and the data were subjected to smallest space analysis (SSA). Four themes of CNE were identified: Elated Hero, Calm Professional, Distressed Revenger, and Depressed Victim in line with the recent theoretical framework posited for narrative offence roles. The theoretical implications for understanding crime on the basis of the CNE as well as practical implications are discussed.

The author proposes a new model for the assessment of decision-making capacity based on the principles of narrative medicine. The narrative method proposed by the author addresses the hidden power realtionships implicit in the current model of capacity assessment. Sample cases are reviewed using the traditional model in comparison with the narrative model. Narrative medicine provides an effective model for the assessment of decision-making capacity. Deficiencies in the traditional model capacity assessment can be effectively addressed using narrative strategies. © 2015 John Wiley & Sons, Ltd.

From naturalistic neuroscience to modeling radical embodiment with narrative enactive systems

Mainstream cognitive neuroscience has begun to accept the idea of embodied mind, which assumes that the human mind is fundamentally constituted by the dynamical interactions of the brain, body, and the environment. In today’s paradigm of naturalistic neurosciences, subjects are exposed to rich contexts, such as video sequences or entire films, under relatively controlled conditions, against which researchers can interpret changes in neural responses within a time window. However, from the point of view of radical embodied cognitive neuroscience, the increasing complexity alone will not suffice as the explanatory apparatus for dynamical embodiment and situatedness of the mind. We suggest that narrative enactive systems with dynamically adaptive content as stimuli, may serve better to account for the embodied mind engaged with the surrounding world. Among the ensuing challenges for neuroimaging studies is how to interpret brain data against broad temporal contexts of previous experiences that condition the unfolding experience of nowness. We propose means to tackle this issue, as well as ways to limit the exponentially growing combinatoria of narrative paths to a controllable number. PMID:25339890

Black-Right-Pointing-Pointer Microstructural deviation from the equilibrium phase diagram. Black-Right-Pointing-Pointer Disparity in texture of these alloys after hot-rolling (recrystallization and grain growth). Black-Right-Pointing-Pointer Role of alloying and phase distribution in affecting the texture/interplaner spacing. - Abstract: In the present study, the influence of alloying and thermomechanical processing on the microstructure and texture evolution on the two Mg-Li-Al based alloys, namely Mg-9 wt% Li-7 wt% Al-1 wt% Sn (LAT971) and Mg-9 wt% Li-5 wt% Al-3 wt% Sn-1 wt% Zn (LATZ9531) has been elicited. Novel Mg-Li-Al based alloys were cast (induction melting under protective atmosphere) followed by hot rolling at {approx}573 K with a cumulative reduction of five. A contrary dual phase dendritic microstructure rich in {alpha}-Mg, instead of {beta}-Li phase predicted by equilibrium phase diagram of Mg-Li binary alloy was observed. Preferential presence of Mg-Li-Sn primary precipitates (size 4-10 {mu}m) within {alpha}-Mg phase and Mg-Li-Al secondary precipitates (<3 {mu}m) interspersed in {beta}-Li indicated their degree of dissolution during hot-rolling and homogenization in the dual phase matrix. Presence of Al, Sn and Zn alloying elements in the Mg-Li based alloy has resulted an unusual dual-phase microstructure, change in the lattice parameter, and intriguing texture evolution after hot-rolling of cast LAT 971 and LATZ9531 alloy. Strong texture was absent in the as-cast samples whereas texture development after hot-rolling revealed an increased activity of the non-basal (101{sup Macron }0) slip planes. The quantification of the grain average misorientation (less than 2 Degree-Sign ) using electron backscattered diffraction confirmed the presence of strain free grains in majority of the grains (fraction >0.75) after hot-rolling of Mg

Magma-sediment interactions in the evaporite-rich Tunguska Basin resulted in the formation of numerous phreatomagmatic pipes during emplacement of the Siberian Traps. The pipes contain magnetite-apatite deposits with copper and celestine mineralization. We have performed a detailed petrographic and geochemical study of magnetite from long cores drilled through three pipe breccia structures near Bratsk, East Siberia. The magnetite samples are zoned and rich in Si (≤5.3 wt% SiO2), Ca, Al, and Mg. They exhibit four textural types: (1) massive ore in veins, (2) coating on breccia clasts, (3) replacement ore, and (4) reworked ore at the crater base. The textural types have different chemical characteristics. "Breccia coating" magnetite has relatively low Mg content relative to Si, as compared to the other groups, and appears to have formed at lower oxygen fugacity. Time series analyses of MgO variations in microprobe transects across Si-bearing magnetite in massive ore indicate that oscillatory zoning in the massive ore was controlled by an internal self-organized process. We suggest that hydrothermal Fe-rich brines were supplied from basalt-sediment interaction zones in the evaporite-rich sedimentary basin, leading to magnetite ore deposition in the pipes. Hydrothermal fluid composition appears to be controlled by proximity to dolerite fragments, temperature, and oxygen fugacity. Magnetite from the pipes has attributes of iron oxide-apatite deposits (e.g., textures, oscillatory zoning, association with apatite, and high Si content) but has higher Mg and Ca content and different mineral assemblages. These features are similar to magnetite found in skarn deposits. We conclude that the Siberian Traps-related pipe magnetite deposit gives insight into the metamorphic and hydrothermal effects following magma emplacement in a sedimentary basin.

Advecting Procedural Textures for 2D Flow Animation

Kao, David; Pang, Alex; Moran, Pat (Technical Monitor)

2001-01-01

This paper proposes the use of specially generated 3D procedural textures for visualizing steady state 2D flow fields. We use the flow field to advect and animate the texture over time. However, using standard texture advection techniques and arbitrary textures will introduce some undesirable effects such as: (a) expanding texture from a critical source point, (b) streaking pattern from the boundary of the flowfield, (c) crowding of advected textures near an attracting spiral or sink, and (d) absent or lack of textures in some regions of the flow. This paper proposes a number of strategies to solve these problems. We demonstrate how the technique works using both synthetic data and computational fluid dynamics data.

I will propose three categories by which a narrative interpretive approach can be applied to financial communication: narrative-as-artifacts, narrative......-as-practice and narrative-as-method. Such a constitutive communication approach challenges a mechanistic and functionalist view of communication as a tool to represent social realities in favor of an interpretive view that could remain sensitive to the production and reproduction of meaning by the actors involved....

Levels of narrative analysis in health psychology.

Science.gov (United States)

Murray, M

2000-05-01

The past 10-15 years have seen a rapid increase in the study of narrative across all the social sciences. It is sometimes assumed that narrative has the same meaning irrespective of the context in which it is expressed. This article considers different levels of narrative analysis within health psychology. Specifically, it considers the character of health and illness narratives as a function of the personal, interpersonal, positional and societal levels of analysis. At the personal level of analysis narratives are portrayed as expressions of the lived experience of the narrator. At the interpersonal level of analysis the narrative is one that is co-created in dialogue. At the positional level of analysis the analysis considers the differences in social position between the narrator and the listener. The societal level of analysis is concerned with the socially shared stories that are characteristic of certain communities or societies. The challenge is to articulate the connections between these different levels of narrative analysis and to develop strategies to promote emancipatory narratives.

2014-09-01

Pinto beans were milled and then air-classified to obtain a raw high protein fraction (RHPF) followed by extrusion to texturize the protein fraction. The texturized high protein fraction (THPF) was then milled to obtain flour, and combined with wheat flour at 5, 10, and 15% levels to make bread. The air-classification process produced flour with high concentration of lipids and phytic acid in the protein-rich fraction. However, extrusion significantly reduced hexane extractable lipid and phytic acid. However, the reduction observed may simply indicate a reduction in recovery due to bind with other components. Total protein and lysine contents in composite flours increased significantly as THPF levels increased in composite flour. Bread made with 5% THPF had 48% more lysine than the 100 % wheat flour (control). The THPF helped to maintain dough strength by reducing mixing tolerance index (MTI), maintaining dough stability and increasing departure time on Farinograph. Bread loaf volume was significantly reduced above 5% THPF addition. THPF increased water absorption causing an increase in bread weights by up to 6%. Overall, loaf quality deteriorated at 10 and 15% THPF levels while bread with 5% THPF was not significantly different from the control. These results support the addition of 5% THPF as a means to enhance lysine content of white pan bread.

Formation of textured strontium titanate (STO) layers with large lateral grain size (0.2–1 μm) and low X-ray reflectivity roughness (∼ 1.36 nm) on Pt electrodes by industry proven atomic layer deposition (ALD) method is demonstrated. Sr(t-Bu 3 Cp) 2 , Ti(OMe) 4 and O 3 precursors at 250 °C were used to deposit Sr rich STO on Pt/Ti/SiO 2 /Si ∅200 mm substrates. After crystallization post deposition annealing at 600 °C in air, most of the STO grains showed a preferential orientation of the {001} plane parallel to the substrate surface, although other orientations were also present. Cross sectional and plan view transmission electron microscopy and electron diffraction analysis revealed more than an order of magnitude larger lateral grain sizes for the STO compared to the underlying multicrystalline {111} oriented platinum electrode. The combination of platinum bottom electrodes with ALD STO(O 3 ) shows a promising path towards the formation of single oriented STO film. - Highlights: ► Amorphous strontium titanate (STO) on platinum formed a textured film after annealing. ► Single crystal domains in 60 nm STO film were 0.2–1 μm wide. ► Most STO grains were {001} oriented.

Efficient iris texture analysis method based on Gabor ordinal measures

With the remarkably increasing interest directed to the security dimension, the iris recognition process is considered to stand as one of the most versatile technique critically useful for the biometric identification and authentication process. This is mainly due to every individual's unique iris texture. A modestly conceived efficient approach relevant to the feature extraction process is proposed. In the first place, iris zigzag "collarette" is extracted from the rest of the image by means of the circular Hough transform, as it includes the most significant regions lying in the iris texture. In the second place, the linear Hough transform is used for the eyelids' detection purpose while the median filter is applied for the eyelashes' removal. Then, a special technique combining the richness of Gabor features and the compactness of ordinal measures is implemented for the feature extraction process, so that a discriminative feature representation for every individual can be achieved. Subsequently, the modified Hamming distance is used for the matching process. Indeed, the advanced procedure turns out to be reliable, as compared to some of the state-of-the-art approaches, with a recognition rate of 99.98%, 98.12%, and 95.02% on CASIAV1.0, CASIAV3.0, and IIT Delhi V1 iris databases, respectively.

Full Text Available This article is a proposal of identity research through its process and narrative character. As a starting point I present a definition of identity understood as the whole life process of finding identification. Next I present my own model of auto/biography-narrative research inspired by hermeneutic and phenomenological traditions of thinking about experiencing reality. I treat auto/biography-narrative research as a means of exploratory conduct, based on the narrator’s biography data, also considering the researcher’s autobiographical thought. In the final part of the article I focus on showing the narrative structure of identity and autobiography. I emphasise this relation in definitions qualifying autobiography as written life narration and identity as a narration of autobiography.

Constructing and Reconstructing Narrative Identity

Full Text Available The research work done by the author investigates a phenomenological field—the subjective experience of chronic illness and disability—by means of a specific research instrument, the autobiographical narrative interview. It focuses on the concept of narrative identity and its empirical substrate in the scientifically generated texts. Narrative identity is regarded as a situated, pragmatic, autoepistemic and interactive activity drawing on culturally transmitted narrative conventions which is performed within the research context. We have been working with a systematic analytic approach which covers interactive and contextual aspects of the interview situation as well as rhetoric and positioning strategies in the act of telling. Other research questions concern the concept of "narrative coping" and the comparison of partner's narratives on problems of illness and disability, especially on scrutinizing aspects of identity and alterity (self and other in the texts. This work can be understood as combining aspects of the research domains of narratology, identity and coping on the background of a qualitative methodology. URN: urn:nbn:de:0114-fqs0002189

Aims. This study evaluated the effects of L-PRF presence and implant surface texture on bone healing around immediately placed implants. Methods. The first mandibular molars of 8 beagle dogs were bilaterally extracted, and implants (Blossom™, Intra-Lock International, Boca Raton, FL) were placed in the mesial or distal extraction sockets in an interpolated fashion per animal. Two implant surfaces were distributed per sockets: (1) dual acid-etched (DAE, micrometer scale textured) and (2) micrometer/nanometer scale textured (Ossean™ surface). L-PRF (Intraspin system, Intra-Lock International) was placed in a split-mouth design to fill the macrogap between implant and socket walls on one side of the mandible. The contralateral side received implants without L-PRF. A mixed-model ANOVA (at α = 0.05) evaluated the effect of implant surface, presence of L-PRF, and socket position (mesial or distal), individually or in combination on bone area fraction occupancy (BAFO). Results. BAFO values were significantly higher for the Ossean relative to the DAE surface on the larger mesial socket. The presence of L-PRF resulted in higher BAFO. The Ossean surface and L-PRF presence resulted in significantly higher BAFO. Conclusion. L-PRF and the micro-/nanometer scale textured surface resulted in increased bone formation around immediately placed implants. PMID:28042577

Cascaded Amplitude Modulations in Sound Texture Perception

Richard McWalter

2017-09-01

Full Text Available Sound textures, such as crackling fire or chirping crickets, represent a broad class of sounds defined by their homogeneous temporal structure. It has been suggested that the perception of texture is mediated by time-averaged summary statistics measured from early auditory representations. In this study, we investigated the perception of sound textures that contain rhythmic structure, specifically second-order amplitude modulations that arise from the interaction of different modulation rates, previously described as “beating” in the envelope-frequency domain. We developed an auditory texture model that utilizes a cascade of modulation filterbanks that capture the structure of simple rhythmic patterns. The model was examined in a series of psychophysical listening experiments using synthetic sound textures—stimuli generated using time-averaged statistics measured from real-world textures. In a texture identification task, our results indicated that second-order amplitude modulation sensitivity enhanced recognition. Next, we examined the contribution of the second-order modulation analysis in a preference task, where the proposed auditory texture model was preferred over a range of model deviants that lacked second-order modulation rate sensitivity. Lastly, the discriminability of textures that included second-order amplitude modulations appeared to be perceived using a time-averaging process. Overall, our results demonstrate that the inclusion of second-order modulation analysis generates improvements in the perceived quality of synthetic textures compared to the first-order modulation analysis considered in previous approaches.

Natural texture retrieval based on perceptual similarity measurement

A typical texture retrieval system performs feature comparison and might not be able to make human-like judgments of image similarity. Meanwhile, it is commonly known that perceptual texture similarity is difficult to be described by traditional image features. In this paper, we propose a new texture retrieval scheme based on texture perceptual similarity. The key of the proposed scheme is that prediction of perceptual similarity is performed by learning a non-linear mapping from image features space to perceptual texture space by using Random Forest. We test the method on natural texture dataset and apply it on a new wallpapers dataset. Experimental results demonstrate that the proposed texture retrieval scheme with perceptual similarity improves the retrieval performance over traditional image features.

Epitaxial hexagonal materials on IBAD-textured substrates

Matias, Vladimir; Yung, Christopher

2017-08-15

A multilayer structure including a hexagonal epitaxial layer, such as GaN or other group III-nitride (III-N) semiconductors, a oriented textured layer, and a non-single crystal substrate, and methods for making the same. The textured layer has a crystalline alignment preferably formed by the ion-beam assisted deposition (IBAD) texturing process and can be biaxially aligned. The in-plane crystalline texture of the textured layer is sufficiently low to allow growth of high quality hexagonal material, but can still be significantly greater than the required in-plane crystalline texture of the hexagonal material. The IBAD process enables low-cost, large-area, flexible metal foil substrates to be used as potential alternatives to single-crystal sapphire and silicon for manufacture of electronic devices, enabling scaled-up roll-to-roll, sheet-to-sheet, or similar fabrication processes to be used. The user is able to choose a substrate for its mechanical and thermal properties, such as how well its coefficient of thermal expansion matches that of the hexagonal epitaxial layer, while choosing a textured layer that more closely lattice matches that layer.

Valuing narrative in the care of older people: a framework of narrative practice for older adult residential care settings.

Buckley, Catherine; McCormack, Brendan; Ryan, Assumpta

2014-09-01

To report on the development of a framework of narrative practice, in residential care settings for older people. Residential care settings for older people provide care for people who are no longer able to live in their own home. To date, the impact and structure of nursing practice on care provision in these settings has proved difficult to conceptualise within a specific nursing theory framework. A hermeneutic approach incorporating narrative methods was used. Forty-six narrative interviews with older people in residential care were secondary-analysed for key themes through a three-stage process: by the first author, four focus groups of 12 clinical nurse managers and two independent experts. Themes were also derived from a focus group of eight residents who explored person-centredness and narrative. Finally, the combined findings were used to derive a single set of themes. The secondary data analysis process led to the development of a framework of narrative practice for the care of older people in residential settings. The framework is influenced by narrative enquiry, person-centred practice and practice development. It has four pillars, prerequisites, care processes, care environment and narrative aspects of care. To operationalise the framework of narrative practice, three narrative elements, narrative knowing, narrative being and narrative doing, need to be considered. Working with the foundational pillars and the narrative elements would enable staff to 'work in a storied way' and provide person-centred outcomes and a narrative informed philosophy of care for older adults in residential care. This framework provides nurses with a template that confirms the identity of the older person taking account of their biography. The framework outlines an approach that provides staff with a template on how to provide person-centred care in a narrative way. © 2013 John Wiley & Sons Ltd.

Traditionally most health education materials are written in an expository non-narrative format. Scholars have argued that the effectiveness of materials may increase when these texts are replaced by narrative texts, and that the non-narrative texts should be replaced by narrative texts. However, no previous studies have tested these claims in the context of school health education for low educated adolescents. This study aims to do so for an existing preventive health education intervention about alcohol for low educated adolescents. Based on the empirical findings of previous studies, it is expected that the claims about narratives being more effective than non-narrative texts are not true for effects on knowledge. Instead non-narrative texts are expected to have a stronger impact on this outcome variable. For attitude towards alcohol and intention to drink alcohol the claims are expected to be true, because participants are expected to be less aware of the persuasive intent of the narrative texts, which would make them less resistant. As a result, narrative texts are expected to have a stronger effect on attitude and intention. This study compares the effects on knowledge, attitude towards alcohol, and intention to drink alcohol of both information formats in a two-condition (non-narrative vs. narrative information) experiment with repeated measures (pre-measurement, immediate post-measurement, and delayed post-measurement). The experiment was conducted amongst 296 students of the two lowest levels of the Dutch secondary education system. The results showed immediate effects on knowledge and attitude towards alcohol, which did not differ between conditions and school levels. These effects did not persist over time. There were no effects on intention to drink alcohol. It is concluded non-narrative and narrative information are equally effective in the context of school health education, suggesting the claims that scholars have made about the superior effects of

structure, he doesn’t have to notice all capacities of the word. One of them is visual function and the other is word's phonetic capacity. The advantage that a poet can take from word's sound and form of writing to increase the dramatic richness of Ghazal in the story is by no means available.   Differences between narrative Ghazal and cinematic narrative   1- From the viewpoint of power of play, perhaps the major advantage the literature has over films is that a poem does not need any facilities except words to make up atmosphere and design the scene. This advantage makes poetry capable to image surreal spaces that film can not show .   2- In Ghazal, just the special signs that poet wanted is conveyed to the audience namely the author's control is more. So whenever he wants, makes the audience to focus his attention on the text or, on the contrary, divert attention away from.   Similarities between narrative Ghazal and cinematic narrative   1- Sometimes, sense and experience that the sequence of short words and phrases of Ghazal suggest to audience is the same as experience the serial of film shots convey.   2- The reader of story - even a short story– has opportunity as well as possibility to read and review each part of the story he prefers , but the movie spectator does not . Considering this, Ghazal is closer to cinema than story. Because, Ghazal is a poem to be read rather than listened , and due to the brevity prevailing over the space of poetry and Ghazal's structural limitations, poet has little opportunity to convey a sense and to present an artistic experience .   3-Today poetry uses the pattern of stanza in its formal system , like plan and shot employed in cinema. This more than verse and hemistich shows temporal and spatial distances , events and sections in the vertical axis of poetry. Such a way that each stanza expresses one temporal and spatial feature of the detached narration , whereas the sections and

Full Text Available This essay argues for narrative competence as an underlying skill neglected in educational policy makers’ calls for enhanced literacy through improved reading, writing, numeracy and working with digital technology. This argument is presented in three parts. First, a genealogy of the narrative is presented by looking at understandings of narratives with respect to changes in technology and socio-cultural relations. Three technological forms of the narrative are examined: the oral, written and image based narrative. Second, revisiting Bernstein, narrative competency is connected to pedagogic practice. The focus is upon code recognition and the rhythm of narrative in a classroom context. Third, a proposal is made to develop narrative competence as a research programme capable of exploring literacy in an age of open learning. The core assertion of this essay is that when narrative is understood in a multi-directional, multi-voiced and multi-punctual sense, opportunities are created for a pedagogic practice that is in tune with the demands placed upon youth and their relationship to changing technologies. This makes the exploration of connections between narrative competence, pedagogic practice and technology the central focus of this essay.

The relationship between oral language and the writing process at early acquisition stages and the ways the former can enhance or limit the latter has not been researched extensively. The predictive relationship between kindergarten oral narrative competence and the first- and second-grade written narrative competence was explored in a 3-year longitudinal study. Among the first and second graders, the relationship between orthographic competence and narrative competence in written productions was also analysed. One hundred and nine Italian children participated in this study. Kindergarteners produced an oral narrative, whereas the first and second graders produced a written narrative. The oral and written narratives were analysed in terms of cohesion, coherence, and structure. The first-grade orthographic competence was assessed via a dictation task. Multiple linear regression and mediational analyses were performed. Kindergarten oral narrative competence affected the first- and second-grade written narrative competence via a mediational effect of orthographic competence. The results suggest the importance of practicing oral narrative competence in kindergarten and first grade and the value of composition quality independent of orthographic text accuracy. © 2015 The British Psychological Society.

A Review Paper on Camouflage Texture Evaluation

Traditional evaluation method of camouflage texture effect is subjective evaluation. It’s very tedious and inconvenient to direct the texture designing. In this project, a systemic and rational method for direction and evaluation of camouflage texture designing is proposed. Camouflage consists of things such as leaves, branches, or brown and green paint, which are used to make it difficult for an enemy to see military forces and equipment. A camouflage texture evaluation method based on WSSIM...

An equiaxed grained as-cast strip and a columnar grained as-cast strip was produced by using twin-roll strip casting, respectively. Both as-cast strips mainly containing 0.71 wt%Si and 0.44 wt%Al were cold rolled and annealed with or without the hot rolling prior to cold rolling. Microstructure, texture evolution along the whole processing routes and the magnetic properties were investigated in detail. It was found that the equiaxed grained strip was characterized by almost random texture while the columnar grained strip was dominated by strong λ-fiber (<001>‖ND) texture. After cold rolling and annealing, all the final sheets of both the as-cast strips showed extremely weak γ-fiber (<111>‖ND) recrystallization texture. In addition, the finally annealed sheets of the equiaxed grained strip were dominated by relatively weak λ-fiber and strong Goss ({110}<001>) recrystallization texture while those of the columnar grained strip were dominated by much stronger λ-fiber and much weaker Goss recrystallization texture regardless of whether the hot rolling was adopted before cold rolling, thus the former showed much lower magnetic induction than the latter. On the other hand, even though the finally annealed sheets of the equiaxed grained strip showed a little more homogeneous recrystallization microstructure with a little bigger grain size than those of the columnar grained strip in the case of no hot rolling, a much higher iron loss was displayed. By contrast, in the case of hot rolling, the former exhibited a little lower iron loss than the latter as a result of the more significant increase in grain size and λ-fiber recrystallization texture. The introduction of the hot rolling could increase the grain size, strengthen λ-fiber texture and weaken Goss texture of the finally annealed sheets of both the as-cast strips, leading to a much improvement in both the magnetic induction and iron loss. - Highlights: • Equiaxed and columnar grained as-cast strips were

Bayesian exploration for intelligent identification of textures

Full Text Available In order to endow robots with humanlike abilities to characterize and identify objects, they must be provided with tactile sensors and intelligent algorithms to select, control and interpret data from useful exploratory movements. Humans make informed decisions on the sequence of exploratory movements that would yield the most information for the task, depending on what the object may be and prior knowledge of what to expect from possible exploratory movements. This study is focused on texture discrimination, a subset of a much larger group of exploratory movements and percepts that humans use to discriminate, characterize, and identify objects. Using a testbed equipped with a biologically inspired tactile sensor (the BioTac® we produced sliding movements similar to those that humans make when exploring textures. Measurement of tactile vibrations and reaction forces when exploring textures were used to extract measures of textural properties inspired from psychophysical literature (traction, roughness, and fineness. Different combinations of normal force and velocity were identified to be useful for each of these three properties. A total of 117 textures were explored with these three movements to create a database of prior experience to use for identifying these same textures in future encounters. When exploring a texture, the discrimination algorithm adaptively selects the optimal movement to make and property to measure based on previous experience to differentiate the texture from a set of plausible candidates, a process we call Bayesian exploration. Performance of 99.6% in correctly discriminating pairs of similar textures was found to exceed human capabilities. Absolute classification from the entire set of 117 textures generally required a small number of well-chosen exploratory movements (median=5 and yielded a 95.4% success rate. The method of Bayesian exploration developed and tested in this paper may generalize well to other

BREAD CRUMBS TEXTURE OF SPELT

Directory of Open Access Journals (Sweden)

Joanna Korczyk – Szabó

2014-02-01

Full Text Available Texture analysis is an objective physical examination of baked products and gives direct information on the product quality, oppositely to dough rheology tests what inform on the baking suitability of the flour, as raw material. Evaluation of the mechanical properties of bread crumb is important not only for quality assurance in the bakeries, but also for assessing the effects of changes in dough ingredients and processing condition and also for describing the changes in bread crumb during storage. Crumb cellular structure is an important quality criterion used in commercial baking and research laboratories to judge bread quality alongside taste, crumb colour and crumb physical texture. In the framework of our research during the years 2010 – 2011 were analyzed selected indicators of bread crumb for texture quality of three Triticum spelta L. cultivars – Altgold, Rubiota and Ostro grown in an ecological system. The bread texture quality was evaluated on texture analyzer TA.XT Plus (Stable Micro Systems, Surrey, UK, following the AACC (74-09 standard and expressed as crumb firmness (N, stiffness (N.mm-1 and relative elasticity (%. Our research proved that all selected indicators were significantly influenced by the year of growing and variety. The most soft bread was achieved in Rubiota, whereas bread crumb samples from Altgold and Ostro were the most firm and stiff. Correlation analysis showed strong negative correlation between relative elasticity and bread crumb firmness as well as bread stiffness (-0.65++, -0.66++. The spelt wheat bread crumb texture need further investigation as it can be a reliable quality parameter.

Correlation between macro texture measures carried out by the volumetric method and by different laser texture meter

International Nuclear Information System (INIS)

Parra Ruiz, L.; Yanguas Gonzalez, S. J.

2013-01-01

The reference value for the measurement of surface macro texture in the Spanish Main Road Network is the MTD or Mean Texture Depth (PMT, Profundidad Media de Textura), obtained by means of the volumetric methods, in accordance with the standard UNE EN 13036-1:12010. The fact that it is a spot measurement that requires road closures makes it an expensive procedure as well as slow and dangerous. In addition to this, the test results are relatively sensitive to the operator, being the procedure not too suitable for systematic surveys. These are some of the reasons that have contributed to the development of texture meter laser devices that can be assembled on board of vehicles, circulating without interfering with the normal traffic flow and providing a parameter named the MPD (Mean Depth Profile). According to the standard UNE-EN ISO 13473-1:2006, it is possible to estimate the texture obtained by volumetric methods, with the parameter ETD (Estimated Texture Depth) through the equation: ETD=0,8 x MPD+0.2 In 2008 CEDEX conducted a study that correlated macro texture measures obtained by means of the volumetric method with such carried out by different laser texture meters. The equations yield a better relation between MPD and MTD were dependent on the measurement device used and were not linear equations type, as is it indicated in the standard, but exponential type equations.

Epitaxial hexagonal materials on IBAD-textured substrates

Energy Technology Data Exchange (ETDEWEB)

Matias, Vladimir; Yung, Christopher

2017-08-15

A multilayer structure including a hexagonal epitaxial layer, such as GaN or other group III-nitride (III-N) semiconductors, a <111> oriented textured layer, and a non-single crystal substrate, and methods for making the same. The textured layer has a crystalline alignment preferably formed by the ion-beam assisted deposition (IBAD) texturing process and can be biaxially aligned. The in-plane crystalline texture of the textured layer is sufficiently low to allow growth of high quality hexagonal material, but can still be significantly greater than the required in-plane crystalline texture of the hexagonal material. The IBAD process enables low-cost, large-area, flexible metal foil substrates to be used as potential alternatives to single-crystal sapphire and silicon for manufacture of electronic devices, enabling scaled-up roll-to-roll, sheet-to-sheet, or similar fabrication processes to be used. The user is able to choose a substrate for its mechanical and thermal properties, such as how well its coefficient of thermal expansion matches that of the hexagonal epitaxial layer, while choosing a textured layer that more closely lattice matches that layer.

Lodi-Smith, Jennifer; Geise, Aaron C; Roberts, Brent W; Robins, Richard W

2009-03-01

The present research investigated the longitudinal relations between personality traits and narratives. Specifically, the authors examined how individual differences in 170 college students' narratives of personality change (a) were predicted by personality traits at the beginning of college, (b) related to actual changes and perceived changes in personality traits during college, and (c) related to changes in emotional health during college. Individual differences in narratives of personality trait change told in the 4th year of college fell into 2 dimensions: affective processing, characterized by positive emotions, and exploratory processing, characterized by meaning making and causal processing. Conscientious, open, and extraverted freshmen told exploratory stories of change as seniors. Emotionally healthy freshmen told stories of change that were high in positive affect. Both positive affective and exploratory stories corresponded to change in emotional stability and conscientiousness during college above and beyond the effects of perceived changes in these traits. In addition, both positive affective and exploratory narratives corresponded to increases in emotional health during college independent of the effects of changes in personality traits. These findings improve our understanding of how individuals conceptualize their changing identity over time.

Texture-dependent effects of pseudo-chewing sound on perceived food texture and evoked feelings in response to nursing care foods.

Endo, Hiroshi; Ino, Shuichi; Fujisaki, Waka

2017-09-01

Because chewing sounds influence perceived food textures, unpleasant textures of texture-modified diets might be improved by chewing sound modulation. Additionally, since inhomogeneous food properties increase perceived sensory intensity, the effects of chewing sound modulation might depend on inhomogeneity. This study examined the influences of texture inhomogeneity on the effects of chewing sound modulation. Three kinds of nursing care foods in two food process types (minced-/puréed-like foods for inhomogeneous/homogeneous texture respectively) were used as sample foods. A pseudo-chewing sound presentation system, using electromyogram signals, was used to modulate chewing sounds. Thirty healthy elderly participants participated in the experiment. In two conditions with and without the pseudo-chewing sound, participants rated the taste, texture, and evoked feelings in response to sample foods. The results showed that inhomogeneity strongly influenced the perception of food texture. Regarding the effects of the pseudo-chewing sound, taste was less influenced, the perceived food texture tended to change in the minced-like foods, and evoked feelings changed in both food process types. Though there were some food-dependent differences in the effects of the pseudo-chewing sound, the presentation of the pseudo-chewing sounds was more effective in foods with an inhomogeneous texture. In addition, it was shown that the pseudo-chewing sound might have positively influenced feelings. Copyright © 2017 Elsevier Ltd. All rights reserved.

What about narrative dentistry?

Science.gov (United States)

Vergnes, Jean-Noel; Apelian, Nareg; Bedos, Christophe

2015-06-01

Narrative medicine strives toward a humanized form of medicine in which empathy and the ability to listen are developed with the same emphasis as scientific rigor. We hypothesize that the adoption of narrative medicine in dentistry would be an excellent method to cultivate the philosophy behind the emerging clinical concept of patient-centered dentistry. Reading literary works, reflective writing, and creative writing would sensitize practitioners to the daily lives of people, human uniqueness, and alterity. Narrative dentistry could lead to more empathic and self-aware practices, and improve dental professionals' observational abilities by making them more perceptive and more attentive to image, metaphor, and meaning. The introduction of narrative dentistry would enrich the clinical clerkship of dentists by bringing the often-missing humanities to the dental professional, academic, and scientific environment.

Three-dimensional topological insulators support a metallic non-trivial surface state with unique spin texture, where spin and momentum are locked perpendicular to each other. In this work, we investigate the orbital selective spin-texture associated with the topological surface states in Sb2Te{sub 3}, using the first principles calculations. Sb2Te{sub 3} is a strong topological insulator with a p-p type bulk band inversion at the Γ-point and supports a single topological metallic surface state with upper (lower) Dirac-cone has left (right) handed spin-texture. Here, we show that the topological surface state has an additional locking between the spin and orbitals, leading to an orbital selective spin-texture. The out-of-plane orbitals (p{sub z} orbitals) have an isotropic orbital texture for both the Dirac cones with an associated left and right handed spin-texture for the upper and lower Dirac cones, respectively. In contrast, the in-planar orbital texture (p{sub x} and p{sub y} projections) is tangential for the upper Dirac-cone and is radial for the lower Dirac-cone surface state. The dominant in-planar orbital texture in both the Dirac cones lead to a right handed orbital-selective spin-texture.

Heterogeneous patterns enhancing static and dynamic texture classification

International Nuclear Information System (INIS)

Silva, Núbia Rosa da; Martinez Bruno, Odemir

2013-01-01

Some mixtures, such as colloids like milk, blood, and gelatin, have homogeneous appearance when viewed with the naked eye, however, to observe them at the nanoscale is possible to understand the heterogeneity of its components. The same phenomenon can occur in pattern recognition in which it is possible to see heterogeneous patterns in texture images. However, current methods of texture analysis can not adequately describe such heterogeneous patterns. Common methods used by researchers analyse the image information in a global way, taking all its features in an integrated manner. Furthermore, multi-scale analysis verifies the patterns at different scales, but still preserving the homogeneous analysis. On the other hand various methods use textons to represent the texture, breaking texture down into its smallest unit. To tackle this problem, we propose a method to identify texture patterns not small as textons at distinct scales enhancing the separability among different types of texture. We find sub patterns of texture according to the scale and then group similar patterns for a more refined analysis. Tests were performed in four static texture databases and one dynamical one. Results show that our method provide better classification rate compared with conventional approaches both in static and in dynamic texture.

The apatite texture of fossil Brachiosaurus brancai and Barosaurus africanus sauropod bones from the excavation site at Tendaguru, Tanzania, was characterized by neutron diffraction pole figures. The results obtained reveal predominantly -fibre textures of the apatite; the fibre direction coincides with the longitudinal direction of the long bones of the skeletons. Neutron pole figures further indicate that other texture types may also be present. Texture strength is similar to dinosaur tendons and contemporary turkey tendon studied by others. Variations of texture strength across the bone wall cross-sections are not significantly large

Master Narratives of Ukrainian Political Culture

Charles McGrath

2018-04-01

Full Text Available As fighting between Russian backed rebels and government forces is taking place in eastern Ukraine, it is all the more apparent the existing political divide that exists in the country. The complex history of being subjugated by surrounding countries and major resettlements of Ukrainians is testing the country in a major way. Historically, emphasis on understanding the Soviet Union was focused on the Soviet perspective — the Soviet narratives, and most recently on reemerging Russia. As a result, little attention is placed on Ukraine’s history. In order to understand the Ukrainian identity, it’s necessary to know the narratives that encompass Ukraine’s history. As freedom and liberty exemplifies American identity and ideology, the history of Ukraine also contains a system of stories that support Ukrainian culture. This paper, the first chapter of my dissertation, details the sources I’ve used to develop my methodology for understanding and analyzing narratives. As I began my research I soon realized the complexity of narratives leading me to explore the elements contained in narratives such as story, plot, character, archetypes, and the Hero’s Journey or Monomyth. I will explain how I understand the meaning of narrative and master narrative, supported by relevant sources, and conclude with the methodology I will use for analysis of the master narratives that envelope the major historical events of Ukraine

Full Text Available In order to solve the problem of texture optimization in 3D city reconstruction by using multi-lens oblique images, the paper presents a method of seamless texture model reconstruction. At first, it corrects the radiation information of images by camera response functions and image dark channel. Then, according to the corresponding relevance between terrain triangular mesh surface model to image, implements occlusion detection by sparse triangulation method, and establishes the triangles' texture list of visible. Finally, combines with triangles' topology relationship in 3D triangular mesh surface model and means and variances of image, constructs a graph-cuts-based texture optimization algorithm under the framework of MRF(Markov random filed, to solve the discrete label problem of texture optimization selection and clustering, ensures the consistency of the adjacent triangles in texture mapping, achieves the seamless texture reconstruction of city. The experimental results verify the validity and superiority of our proposed method.

A suite of eight rocks analyzed by the Curiosity Rover while it was stopped at the Rocknest sand ripple shows the greatest chemical divergence of any potentially sedimentary rocks analyzed in the early part of the mission. Relative to average Martian soil and to the stratigraphically lower units encountered as part of the Yellowknife Bay formation, these rocks are significantly depleted in MgO, with a mean of 1.3 wt %, and high in Fe, averaging over 20 wt % FeOT, with values between 15 and 26 wt % FeOT. The variable iron and low magnesium and rock texture make it unlikely that these are igneous rocks. Rock surface textures range from rough to smooth, can be pitted or grooved, and show various degrees of wind erosion. Some rocks display poorly defined layering while others seem to show possible fractures. Narrow vertical voids are present in Rocknest 3, one of the rocks showing the strongest layering. Rocks in the vicinity of Rocknest may have undergone some diagenesis similar to other rocks in the Yellowknife Bay Formation as indicated by the presence of soluble calcium phases. The most reasonable scenario is that fine-grained sediments, potentially a mixture of feldspar-rich rocks from Bradbury Rise and normal Martian soil, were lithified together by an iron-rich cement.

Characterization of a texture gradient in tantalum plate

International Nuclear Information System (INIS)

Wright, S.I.; Gray, G.T. III.

1994-01-01

Clark et al. have shown that significant texture gradients can be produced in rolled tantalum plate and that the strength of the gradient is dependent on the processing path. Texture gradients are often ignored because they are time consuming to characterize and add significant complexity to materials modeling. The variation in texture through the thickness of rolled materials is most commonly measured by sectioning samples to different depths through the thickness of the plate and then measuring the texture from these section planes by X-ray diffraction. A new technique based on automatic indexing of electron backscatter diffraction patterns in the scanning electron microscope enables spatially specific orientations to be measured in a practical manner. This technique allows spatial variations in texture to be measured directly enabling gradients in texture to be investigated in more detail than previously possible. This data can be used directly in coupled finite-element/polycrystal-plasticity models to simulate the effects of variations in texture on the plastic behavior of polycrystals. This work examines the variation in texture through the thickness of a tantalum plate and its resultant effect on the compressive deformation of samples prepared from the plate. The characterization of the texture gradient using the automatic point-by-point measurement technique mentioned above is described in detail. The effect of the gradient on the plastic response of through-thickness compression tests is also discussed

Effects of alkali on protein polymerization and textural characteristics of textured wheat protein.

Li, Ting; Guo, Xiao-Na; Zhu, Ke-Xue; Zhou, Hui-Ming

2018-01-15

The impact of alkali addition on the degree of gluten polymerization and textural characteristics of textured wheat protein was investigated. Results showed that the extrusion process increased the average molecular weight of gluten as evidenced by SDS-PAGE and SDS extractable protein. The addition of alkali not only promoted the degree of gluten polymerization, but also induced dehydroalanine-derived cross-linking. Alkali addition decreased the content of cystine and increased the contents of dehydroalanine and lanthionine. The obvious decrease of free SH showed that dehydroalanine-derived cross-linking was quantitatively less crucial than disulfide cross-linking. Furthermore, the protein cross-linking induced by alkali improved the texture properties of gluten extrudates. SEM analysis showed extrusion under alkaline condition conferred a more fibrous microstructure as a consequence of a compact gluten network. Copyright © 2017 Elsevier Ltd. All rights reserved.

Texture and Elastic Anisotropy of Mantle Olivine

Science.gov (United States)

Nikitin, A. N.; Ivankina, T. I.; Bourilitchev, D. E.; Klima, K.; Locajicek, T.; Pros, Z.

Eight olivine rock samples from different European regions were collected for neu- tron texture analyses and for P-wave velocity measurements by means of ultrasonic sounding at various confining pressures. The orientation distribution functions (ODFs) of olivine were determined and pole figures of the main crystallographic planes were calculated. The spatial P-wave velocity distributions were determined at confining pressures from 0.1 to 400 MPa and modelled from the olivine textures. In dependence upon the type of rock (xenolith or dunite) different behavior of both the P-wave veloc- ity distributions and the anisotropy coefficients with various confining pressures was observed. In order to explain the interdependence of elastic anisotropy and hydrostatic pressure, a model for polycrystalline olivine rocks was suggested, which considers the influence of the crystallographic and the mechanical textures on the elastic behaviour of the polycrystal. Since the olivine texture depends upon the active slip systems and the deformation temperature, neutron texture analyses enable us to estimate depth and thermodynamical conditions during texture formation.

A Novel Texture Classification Procedure by using Association Rules

Directory of Open Access Journals (Sweden)

L. Jaba Sheela

2008-11-01

Full Text Available Texture can be defined as a local statistical pattern of texture primitives in observer’s domain of interest. Texture classification aims to assign texture labels to unknown textures, according to training samples and classification rules. Association rules have been used in various applications during the past decades. Association rules capture both structural and statistical information, and automatically identify the structures that occur most frequently and relationships that have significant discriminative power. So, association rules can be adapted to capture frequently occurring local structures in textures. This paper describes the usage of association rules for texture classification problem. The performed experimental studies show the effectiveness of the association rules. The overall success rate is about 98%.

We studied the solid-phase reaction between a thin Ni film and a single crystal Ge(001) or Ge(111) substrate during a ramp anneal. The phase formation sequence was determined using in situ X-ray diffraction and in situ Rutherford backscattering spectrometry (RBS), while the nature and the texture of the phases were studied using X-ray pole figures and transmission electron microscopy. The phase sequence is characterized by the formation of a single transient phase before NiGe forms as the final and stable phase. X-ray pole figures were used to unambiguously identify the transient phase as the ϵ-phase, a non-stoichiometric Ni-rich germanide with a hexagonal crystal structure that can exist for Ge concentrations between 34% and 48% and which forms with a different epitaxial texture on both substrate orientations. The complementary information gained from both RBS and X-ray pole figure measurements revealed a simultaneous growth of both the ϵ-phase and NiGe over a small temperature window on both substrate orientations.

Infiltration is a key process in determining the water balance, but so far effects of earthworms, soil texture, plant species diversity and their interaction on infiltration capacity have not been studied. We measured infiltration capacity in subplots with ambient and reduced earthworm density nested in plots of different plant species (1, 4, and 16 species) and plant functional group richness and composition (1 to 4 groups; legumes, grasses, small herbs, tall herbs). In summer, earthworm presence significantly increased infiltration, whereas in fall effects of grasses and legumes on infiltration were due to plant-mediated changes in earthworm biomass. Effects of grasses and legumes on infiltration even reversed effects of texture. We propose two pathways: (i) direct, probably by modifying the pore spectrum and (ii) indirect, by enhancing or suppressing earthworm biomass, which in turn influenced infiltration capacity due to change in burrowing activity of earthworms. Overall, the results suggest that spatial and temporal variations in soil hydraulic properties can be explained by biotic processes, especially the presence of certain plant functional groups affecting earthworm biomass, while soil texture had no significant effect. Therefore biotic parameters should be taken into account in hydrological applications.

Textural features for radar image analysis

Texture is seen as an important spatial feature useful for identifying objects or regions of interest in an image. While textural features have been widely used in analyzing a variety of photographic images, they have not been used in processing radar images. A procedure for extracting a set of textural features for characterizing small areas in radar images is presented, and it is shown that these features can be used in classifying segments of radar images corresponding to different geological formations.

Meteoric water infiltration in ultramafic rocks leads to serpentinization and the formation of subaerial, low temperature, hydrothermal alkaline springs. Here, we present a detailed investigation of the mineral precipitation mechanisms and textural features of mineral precipitates, along as the geochemical and hydrological characterization, of two alkaline spring systems in the Semail ophiolite (Nasif and Khafifah sites, Wadi Tayin massif). The main aim of the study is to provide new insights into mineral and textural variations in active, on-land, alkaline vents of the Oman ophiolite. Discharge of circulating fluids forms small-scale, localized hydrological catchments consisting in unevenly interconnected ponds. Three different types of waters can be distinguished within the pond systems: i) Mg-type; alkaline (7.9 11.6), Ca-OH-rich waters; and iii) Mix-type waters arising from the mixing of Mg-type and Ca-type waters (9.6 ponds were carried out by X-ray diffraction (XRD), Raman spectroscopy and field-emission scanning electron microscopy coupled to dispersive energy spectroscopy (FE-SEM-EDS). Aragonite and calcite are the dominant minerals (95 vol.%) of the total mineralogical index in all sites. Mg-type waters host hydrated magnesium carbonates (nesquehonite) and magnesium hydroxycarbonate hydrates (artinite) due to evaporation. Brucite, hydromagnesite and dypingite presence in Mix-type waters is spatially controlled by the hydrology of the system and is localized around mixing zones between Ca-type with Mg-type waters. Residence time of discharging waters in the ponds before mixing has an impact on fluid chemistry as it influences the equilibration time with the atmosphere. Acicular aragonite is the main textural type in hyper-alkaline Ca-type waters, acting as a substratum for the growth of calcite and brucite crystals. Low crystallinity, dumbbell shaped and double pyramid aragonite dominates in Mix-type water precipitates. Rate of supersaturation is essential

The apatite texture of fossil Brachiosaurus brancai and Barosaurus africanus sauropod bones from the excavation site at Tendaguru, Tanzania, was characterized by neutron diffraction pole figures. The results obtained reveal predominantly <0 0 0 1>-fibre textures of the apatite; the fibre direction coincides with the longitudinal direction of the long bones of the skeletons. Neutron pole figures further indicate that other texture types may also be present. Texture strength is similar to dinosaur tendons and contemporary turkey tendon studied by others. Variations of texture strength across the bone wall cross-sections are not significantly large.

Moving Picture, Lying Image: Unreliable Cinematic Narratives

Directory of Open Access Journals (Sweden)

Csönge Tamás

2015-08-01

Full Text Available By coining the term “unreliable narrator” Wayne Booth hypothesized another agent in his model besides the author, the implicit author, to explain the double coding of narratives where a distorted view of reality and the exposure of this distortion are presented simultaneously. The article deals with the applicability of the concept in visual narratives. Since unreliability is traditionally considered to be intertwined with first person narratives, it works through subjective mediators. According to scholarly literature on the subject, the narrator has to be strongly characterized, or in other words, anthropomorphized. In the case of film, the main problem is that the narrator is either missing or the narration cannot be attributed entirely to them. There is a medial rupture where the apparatus mediates the story instead of a character’s oral or written discourse. The present paper focuses on some important but overlooked questions about the nature of cinematic storytelling through a re-examination of |the lying flashback in Alfred Hitchcock's Stage Fright. Can a character-narrator control the images the viewer sees? How can the filmic image still be unreliable without having an anthropomorphic narrator? How useful is the term focalization when we are dealing with embedded character-narratives in film?

Micro-textures in plagioclase from 1994–1995 eruption, Barren Island Volcano: Evidence of dynamic magma plumbing system in the Andaman subduction zone

Directory of Open Access Journals (Sweden)

M.L. Renjith

2014-01-01

Full Text Available A systematic account of micro-textures and a few compositional profiles of plagioclase from high-alumina basaltic aa lava erupted during the year 1994–1995, from Barren Island Volcano, NE India ocean, are presented for the first time. The identified micro-textures can be grouped into two categories: (i Growth related textures in the form of coarse/fine-sieve morphology, fine-scale oscillatory zoning and resorption surfaces resulted when the equilibrium at the crystal-melt interface was fluctuated due to change in temperature or H2O or pressure or composition of the crystallizing melt; and (ii morphological texture, like glomerocryst, synneusis, swallow-tailed crystal, microlite and broken crystals, formed by the influence of dynamic behavior of the crystallizing magma (convection, turbulence, degassing, etc.. Each micro-texture has developed in a specific magmatic environment, accordingly, a first order magma plumbing model and crystallization dynamics are envisaged for the studied lava unit. Magma generated has undergone extensive fractional crystallization of An-rich plagioclase in stable magmatic environment at a deeper depth. Subsequently they ascend to a shallow chamber where the newly brought crystals and pre-existing crystals have undergone dynamic crystallization via dissolution-regrowth processes in a convective self-mixing environment. Such repeated recharge-recycling processes have produced various populations of plagioclase with different micro-textural stratigraphy in the studied lava unit. Intermittent degassing and eruption related decompression have also played a major role in the final stage of crystallization dynamics.

2007-08-01

Part 2 of this paper aims to provide a methodological framework for the study of medication narratives, including a semi-structured interview guide and suggested method of analysis, in an attempt to aid the development of narrative scholarship within pharmacy practice research. Examples of medication narratives are provided to illustrate their diversity and usefulness. The framework is derived from the work of other researchers and adapted for our specific purpose. It comes from social psychology, narrative psychology, narrative anthropology, sociology and critical theory and fits within the social constructionist paradigm. The suggested methods of analysis could broadly be described as narrative analysis and discourse analysis. Examples of medication narratives are chosen from a variety of sources and brief interpretations are presented by way of illustration. Narrative analysis, a neglected area of research in pharmacy practice, has the potential to provide new understanding about how people relate to their medicines, how pharmacists are engaged in producing narratives and the importance of narrative in the education of students. IMPACT OF THE ARTICLE: This article aims to have the following impact on pharmacy practice research: Innovative approach to researching and conceptualising the use of medicines. Introduction of a new theoretical perspective and methodology. Incorporation of social science research methods into pharmacy practice research. Development of narrative scholarship within pharmacy.

Global crystallographic textures obtained by neutron and synchrotron radiation

International Nuclear Information System (INIS)

Brokmeier, Heinz-Guenter

2006-01-01

Global crystallographic textures belong to the main characteristic parameters of engineering materials. The global crystallographic texture is always the average texture of a well-defined sample volume which is representative to solve practical engineering problems. Thus a beam having a high penetration power is needed available as neutron or high energetic X-ray radiation. Texture type and texture sharpness are of great importance for materials properties such as the deep drawing behaviour, one of the basic techniques in many industries. Advantages and disadvantages of both radiations make them complementary for measuring crystallographic textures in a wide range of materials

Texture analysis using angle dispersive neutron nuclear scattering

International Nuclear Information System (INIS)

Brokmeier, H.G.

1995-01-01

This paper describes in detail the method of texture determination using neutron diffraction. The main advantages of neutron diffraction arise from the high penetration depth for most materials which is a factor of 10 2 -10 4 higher than for X-ray diffraction. Consequently neutron diffraction is an efficient tool for the investigation of global textures and coarse grained materials. Moreover, the measurement of large sample volumes gives excellent grain statistics, allows the influence of texture inhomogeneities to be neglected and allows the measurement of complete pole figures even of minority phases. A number of examples show the application of neutron diffraction to measure textures of metals, alloys, composites, intermetallic compounds and rocks. A detailed description of TEX-2 the neutron texture diffractometer at GKSS Research Centre is given which is completed by a comparison to other neutron texture diffractometers. (orig.) [de

Magmatic emulsion texture formed by mixing during extrusion, Rauðafell composite complex, Breiðdalur volcano, eastern Iceland

Science.gov (United States)

Charreteur, Gilles; Tegner, Christian

2013-06-01

The Rauðafell composite complex is part of the Neogene Breiðdalur volcano, eastern Iceland and is composed of a composite feeder dyke, a vent structure and a composite flow. The two end-members of the composite complex are rhyolite and basalt, and both are rich in plagioclase macrocrysts: bytownite in basalt and oligoclase in rhyolite. The rhyolite also includes ferroaugite macrocrysts. The mixed rocks are separated in three textural groups related to mixing proportions. When the basaltic end-member is dominant, a hybrid texture with a homogeneous matrix is observed and the only evidence of mixing is the presence of antecrysts of both end-members. When the basaltic end-member represents c. 65 to 30 % of the mixture, we observe emulsion textures composed of finely co-mingled basalt and rhyolite. The difference between these two textural expressions of mixing is due to effects of diffusion. The third texture shows mafic enclaves suspended in a rhyolitic matrix. In these rocks, the proportion of the basaltic end-member is inferior to 30 %, implying that the basalt froze solid in contact with the rhyolite. Zoning of plagioclase shows that the mixing processes are driven initially by highly efficient micro-mingling; the emulsification is possibly a result of compositional gradient stresses (Korteweg stress) between miscible basalt and rhyolite. This is followed by chemical diffusion (hybridisation) and tend to protect antecrysts from reaction with the primitive magmas. When antecrysts originated in the evolved magma, they undergo dissolution due to thermal disequilibrium during mingling and chemical disequilibrium during hybridisation. We argue that such mixing processes are important in producing intermediate rocks in Iceland and elsewhere that shows only the chemical attributes of an origin by mixing. The preservation of emulsion textures is rare and highly dependent on cooling history.

Identification of immune cell infiltration in hematoxylin-eosin stained breast cancer samples: texture-based classification of tissue morphologies

2016-03-01

The characteristics of immune cells in the tumor microenvironment of breast cancer capture clinically important information. Despite the heterogeneity of tumor-infiltrating immune cells, it has been shown that the degree of infiltration assessed by visual evaluation of hematoxylin-eosin (H and E) stained samples has prognostic and possibly predictive value. However, quantification of the infiltration in H and E-stained tissue samples is currently dependent on visual scoring by an expert. Computer vision enables automated characterization of the components of the tumor microenvironment, and texture-based methods have successfully been used to discriminate between different tissue morphologies and cell phenotypes. In this study, we evaluate whether local binary pattern texture features with superpixel segmentation and classification with support vector machine can be utilized to identify immune cell infiltration in H and E-stained breast cancer samples. Guided with the pan-leukocyte CD45 marker, we annotated training and test sets from 20 primary breast cancer samples. In the training set of arbitrary sized image regions (n=1,116) a 3-fold cross-validation resulted in 98% accuracy and an area under the receiver-operating characteristic curve (AUC) of 0.98 to discriminate between immune cell -rich and - poor areas. In the test set (n=204), we achieved an accuracy of 96% and AUC of 0.99 to label cropped tissue regions correctly into immune cell -rich and -poor categories. The obtained results demonstrate strong discrimination between immune cell -rich and -poor tissue morphologies. The proposed method can provide a quantitative measurement of the degree of immune cell infiltration and applied to digitally scanned H and E-stained breast cancer samples for diagnostic purposes.

TEXTURE ANALYSIS OF SPELT WHEAT BREAD

Magdaléna Lacko - Bartošová

2013-02-01

Full Text Available The bread quality is considerably dependent on the texture characteristic of bread crumb. Texture analysis is primarily concerned with the evaluation of mechanical characteristics where a material is subjected to a controlled force from which a deformation curve of its response is generated. It is an objective physical examination of baked products and gives direct information on the product quality, oppositely to dough rheology tests what are inform on the baking suitability of the flour, as raw material. This is why the texture analysis is one of the most helpful analytical methods of the product development. In the framework of our research during the years 2008 – 2009 were analyzed selected indicators of bread crumb for texture quality of three Triticum spelta L. cultivars – Oberkulmer Rotkorn, Rubiota and Franckenkorn grown in an ecological system at the locality of Dolna Malanta near Nitra. The bread texture quality was evaluated on texture analyzer TA.XT Plus and expressed as crumb firmness (N, stiffness (N.mm-1 and relative elasticity (%.Our research proved that all selected indicators were significantly influenced by the year of growing and variety. The most soft bread was measured in Rubiota, whereas bread crumb samples from Franckenkorn were the most firm and stiff. Relative elasticity confirmed that the lowest firmness and stiffness was found in Rubiota bread. The spelt grain can be a good source for making bread flour, but is closely dependent on choice of spelt variety.

Living with a pituitary tumour: a narrative analysis.

Science.gov (United States)

Simpson, Jane; Heath, James; Wall, Gemma

2014-01-01

This study aimed to synthesise the illness narratives of individuals living with a pituitary tumour. Eight adults with a pituitary tumour were recruited from an endocrinology service in the north-west of England. A narrative methodology was adopted which investigated elements of the individual narratives such as metaphor and structure but which also aimed to produce a joint account of experience in this particular illness context by extracting themes across the stories; these are presented as part of a chronological narrative. However, the resulting group story was also analysed in terms of different types of narrative plots. The group narrative started from the recognition of symptoms and then diagnosis though treatment to post-treatment and future plans. In terms of narrative plots, one notable element of the joint narrative was the flow between the culturally dominant restitution narrative, where participants focused on treatment and recovery and the chaos narrative when recovery did not seem possible. The findings contain many elements consistent with previous research; however, the use of a celebrity figure to communicate about the illness experience and a perception that objects or individuals should not be taken at face value emerged as more novel findings.

Narrative as resource for the display of self and identity: The narrative construction of an oppositional identity*

Directory of Open Access Journals (Sweden)

Alba Lucy Guerrero

2011-11-01

Full Text Available Narrative is a system of understanding that we use to construct and express meaning in our daily lives. The stories we narrate are not justresources for the development and presentation of the individual self; they allow us to see how identity is constructed within social and culturalworlds (Bruner, 1990. Schools and communities play a powerful role in shaping students identities; the ways in which stories are told and theidentities they create are influenced by the environment in which they take place. In this paper, by using excerpts from a conversation I hadwith a High School student in an urban school in Bogotá, I will discuss how narrative analysis can be used to understand the way studentsconstruct their identities within their schools and communities. First, I will present the theoretical contexts linking narrative with self-construction.Next, I will discuss the methodological implications in the process of collecting and representing experiences highlighting the possibilities ofnarrative to make visible the construction of identities. Then pieces of a narrative told in a research interview will be analyzed illustrating differentapproaches of narrative analysis. The paper will conclude with a section that outlines the implications of using narrative in educational research.

Some distinguishing characteristics of contour and texture phenomena in images

Science.gov (United States)

Jobson, Daniel J.

1992-01-01

The development of generalized contour/texture discrimination techniques is a central element necessary for machine vision recognition and interpretation of arbitrary images. Here, the visual perception of texture, selected studies of texture analysis in machine vision, and diverse small samples of contour and texture are all used to provide insights into the fundamental characteristics of contour and texture. From these, an experimental discrimination scheme is developed and tested on a battery of natural images. The visual perception of texture defined fine texture as a subclass which is interpreted as shading and is distinct from coarse figural similarity textures. Also, perception defined the smallest scale for contour/texture discrimination as eight to nine visual acuity units. Three contour/texture discrimination parameters were found to be moderately successful for this scale discrimination: (1) lightness change in a blurred version of the image, (2) change in lightness change in the original image, and (3) percent change in edge counts relative to local maximum.

AUTOMATIC TEXTURE RECONSTRUCTION OF 3D CITY MODEL FROM OBLIQUE IMAGES

Directory of Open Access Journals (Sweden)

J. Kang

2016-06-01

Full Text Available In recent years, the photorealistic 3D city models are increasingly important in various geospatial applications related to virtual city tourism, 3D GIS, urban planning, real-estate management. Besides the acquisition of high-precision 3D geometric data, texture reconstruction is also a crucial step for generating high-quality and visually realistic 3D models. However, most of the texture reconstruction approaches are probably leading to texture fragmentation and memory inefficiency. In this paper, we introduce an automatic framework of texture reconstruction to generate textures from oblique images for photorealistic visualization. Our approach include three major steps as follows: mesh parameterization, texture atlas generation and texture blending. Firstly, mesh parameterization procedure referring to mesh segmentation and mesh unfolding is performed to reduce geometric distortion in the process of mapping 2D texture to 3D model. Secondly, in the texture atlas generation step, the texture of each segmented region in texture domain is reconstructed from all visible images with exterior orientation and interior orientation parameters. Thirdly, to avoid color discontinuities at boundaries between texture regions, the final texture map is generated by blending texture maps from several corresponding images. We evaluated our texture reconstruction framework on a dataset of a city. The resulting mesh model can get textured by created texture without resampling. Experiment results show that our method can effectively mitigate the occurrence of texture fragmentation. It is demonstrated that the proposed framework is effective and useful for automatic texture reconstruction of 3D city model.

Narrative journalism as complementary inquiry

Directory of Open Access Journals (Sweden)

Jørgen Jeppesen

2011-10-01

Full Text Available Narrative journalism is a method to craft stories worth reading about real people. In this article, we explore the ability of that communicative power to produce insights complementary to those obtainable through traditional qualitative and quantitative research methods. With examples from a study of journalistic narrative as patient involvement in professional rehabilitation, interview data transcribed as stories are analyzed for qualities of heterogeneity, sensibility, transparency, and reflexivity. Building on sociological theories of thinking with stories, writing as inquiry, and public journalism as ethnography, we suggest that narrative journalism as a common practice might unfold dimensions of subjective otherness of the self. Aspiring to unite writing in both transparently confrontational and empathetically dialogic ways, the narrative journalistic method holds a potential to expose dynamics of power within the interview.

Textural, Rheological and Sensory Properties and Oxidative Stability of Nut Spreads—A Review

Directory of Open Access Journals (Sweden)

Full Text Available Tree nuts are rich in macro and micronutrients, phytochemicals, tocopherols and phenolic compounds. The development of nut spreads would potentially increase the food uses of nuts and introduce consumers with a healthier, non-animal breakfast snack food. Nut spreads are spreadable products made from nuts that are ground into paste. Roasting and milling (particle size reduction are two important stages for the production of nut spreads that affected the textural, rheological characteristic and overall quality of the nut spread. Textural, color, and flavor properties of nut spreads play a major role in consumer appeal, buying decisions and eventual consumption. Stability of nut spreads is influenced by its particle size. Proper combination of ingredients (nut paste, sweetener, vegetable oil and protein sources is also required to ensure a stable nut spread product is produced. Most of the nut spreads behaved like a non-Newtonian pseudo-plastic fluid under yield stress which help the producers how to start pumping and stirring of the nut spreads. Similar to other high oil content products, nut spreads are susceptible to autoxidation. Their oxidation can be controlled by application of antioxidants, using processing techniques that minimize tocopherol and other natural antioxidant losses.

Welch, Ronald M.; Kuo, Kwo-Sen; Sengupta, Sailes K.

1990-01-01

The study examines the textural signatures of clouds, ice-covered mountains, solid and broken sea ice and floes, and open water. The textural features are computed from sum and difference histogram and gray-level difference vector statistics defined at various pixel displacement distances derived from Landsat multispectral scanner data. Polar cloudiness, snow-covered mountainous regions, solid sea ice, glaciers, and open water have distinguishable texture features. This suggests that textural measures can be successfully applied to the detection of clouds over snow-covered mountains, an ability of considerable importance for the modeling of snow-melt runoff. However, broken stratocumulus cloud decks and thin cirrus over broken sea ice remain difficult to distinguish texturally. It is concluded that even with high spatial resolution imagery, it may not be possible to distinguish broken stratocumulus and thin clouds from sea ice in the marginal ice zone using the visible channel textural features alone.

Texture and wettability of metallic lotus leaves

Frankiewicz, C.; Attinger, D.

Superhydrophobic surfaces with the self-cleaning behavior of lotus leaves are sought for drag reduction and phase change heat transfer applications. These superrepellent surfaces have traditionally been fabricated by random or deterministic texturing of a hydrophobic material. Recently, superrepellent surfaces have also been made from hydrophilic materials, by deterministic texturing using photolithography, without low-surface energy coating. Here, we show that hydrophilic materials can also be made superrepellent to water by chemical texturing, a stochastic rather than deterministic process. These metallic surfaces are the first analog of lotus leaves, in terms of wettability, texture and repellency. A mechanistic model is also proposed to describe the influence of multiple tiers of roughness on wettability and repellency. This demonstrated ability to make hydrophilic materials superrepellent without deterministic structuring or additional coatings opens the way to large scale and robust manufacturing of superrepellent surfaces.Superhydrophobic surfaces with the self-cleaning behavior of lotus leaves are sought for drag reduction and phase change heat transfer applications.

Over the past decade, ice cream manufacturers have developed a strong understanding of the functionality of key ingredients and processing, developing effective explanations for the link between structure forming agents, stability mechanisms, and perceived quality. Increasing demand for products perceived as healthier/more natural with minimal processing has identified a number of new tools to improve quality and storage stability of frozen dairy desserts. Ingredients such as dietary fiber, polysaccharides, prebiotics, alternate sweeteners, fat sources rich in unsaturated fatty acids and ice strucsturing proteins (ISP) have been successfully applied as cryoprotective, texturizing, and structuring agents. Emerging minimal processing technologies including hydrostatic pressure processing, ultrasonic or high pressure assisted freezing, low temperature extrusion and enzymatically induced biopolymers crosslinking have been evaluated for their ability to improve colloidal stability, texture and sensory quality. It is therefore timely for a comprehensive review.

Xiaoxia Wang

2002-01-01

Full Text Available The Mesozoic Shahewan pluton consists of four texturally different types of biotite-hornblende quartz monzonite. In the porphyritic types alkali feldspar occurs as euhedral or ovoidal megacrysts that are often mantled by one or more plagioclase shells, and as smaller grains in the groundmass. Quartz, plagioclase (An20–28, biotite, and hornblende occur as inclusions in the alkali feldspar megacrystsand, more abundantly, in the groundmass. Euhedral quartz crystals in the groundmass are not as common and well developed as in typical rapakivi granite. Compared to typical rapakivi granites, the mafic minerals (biotite and hornblende are rich in Mg and poor in Fe, and the whole rock is low in Si, K, F, Ga, Zr, LREE, Fe/Mg, and K/Na. The rocks of the Shahewan pluton are thus regarded as rapakivi-textured quartz monzonites and granites but not true rapakivi granites.

Synthesis of nano-textured biocompatible scaffolds from chicken eggshells

Cell adhesion, morphology and growth are influenced by surface topography at nano and micrometer scales. Nano-textured surfaces are prepared using photolithography, plasma etching and long polymer chemical etching which are cost prohibitive and require specialized equipment. This article demonstrates a simple approach to synthesize nano-textured scaffolds from chicken eggshells. Varieties of pattern are made on the eggshells like micro-needle forests and nanopores, giving very uniform nano-textures to the surfaces. The surfaces are characterized for chemical composition and crystal phase. The novel patterns are transferred to PDMS surfaces and the nano-textured PDMS surfaces are used to study the effect of texturing on human fibroblast cell growth and attachment. The effects of surface topographies, along with laminin coating on cell cultures, are also studied. We find an exciting phenomenon that the initial seeding density of the fibroblast cells affects the influence of the nano-texturing on cell growth. These nano-textured surfaces give 16 times more fibroblast growth when compared to flat PDMS surfaces. The novel nano-textured patterns also double the laminin adsorption on PDMS. (paper)

Visual texture perception via graph-based semi-supervised learning

Zhang, Qin; Dong, Junyu; Zhong, Guoqiang

2018-04-01

Perceptual features, for example direction, contrast and repetitiveness, are important visual factors for human to perceive a texture. However, it needs to perform psychophysical experiment to quantify these perceptual features' scale, which requires a large amount of human labor and time. This paper focuses on the task of obtaining perceptual features' scale of textures by small number of textures with perceptual scales through a rating psychophysical experiment (what we call labeled textures) and a mass of unlabeled textures. This is the scenario that the semi-supervised learning is naturally suitable for. This is meaningful for texture perception research, and really helpful for the perceptual texture database expansion. A graph-based semi-supervised learning method called random multi-graphs, RMG for short, is proposed to deal with this task. We evaluate different kinds of features including LBP, Gabor, and a kind of unsupervised deep features extracted by a PCA-based deep network. The experimental results show that our method can achieve satisfactory effects no matter what kind of texture features are used.

Narrative research on mental health recovery: two sister paradigms.

Despite the breadth of narrative studies on individuals with severe mental illness, the suitability of narrative inquiry to exploring mental health recovery (MHR) has not been examined. (1) Examining the appropriateness of narrative inquiry to studying MHR; (2) assessing the extent to which narrative studies on MHR conform to the unique features of narrative research, as a distinctive form of qualitative inquiry. Review of empirical, theoretical and methodological literature on recovery and narrative inquiry. Considering the perspectives of recovery and narrative as paradigms, the similarity between their ontology and epistemology is shown, evident in 10 common emphases: meaning, identity, change and development, agency, holism, culture, uniqueness, context, language and giving voice. The resemblance between these "sister" paradigms makes narrative methodology especially fruitful for accessing the experiences of individuals in recovery. Reviewing narrative studies on MHR suggests that, currently, narrative research's uniqueness, centered on the holistic principle, is blurred on the philosophical, methodological and textual levels. Well-established narrative research has major implications for practice and policy in recovery-oriented mental health care. The narrative inquiry paradigm offers a possible path to enhancing the distinctive virtues of this research, realizing its potential in understanding and promoting MHR.

Strings, texture, and inflation

Hodges, H.M.; Primack, J.R.

1991-01-01

We examine mechanisms, several of which are proposed here, to generate structure formation, or to just add large-scale features, through either gauged or global cosmic strings or global texture, within the framework of inflation. We first explore the possibility that strings or texture form if there is no coupling between the topological theory and the inflaton or spacetime curvature, via (1) quantum creation, and (2) a sufficiently high reheat temperature. In addition, we examine the prospects for the inflaton field itself to generate strings or texture. Then, models with the string/texture field coupled to the curvature, and an equivalent model with coupling to the inflaton field, are considered in detail. The requirement that inflationary density fluctuations are not so large as to conflict with observations leads to a number of constraints on model parameters. We find that strings of relevance for structure formation can form in the absence of coupling to the inflaton or curvature through the process of quantum creation, but only if the strings are strongly type I, or if they are global strings. If formed after reheating, naturalness suggests that gauged cosmic strings correspond to a type-I superconductor. Similarly, gauged strings formed during inflation via conformal coupling ξ=1/6 to the spacetime curvature (in a model suggested by Yokoyama in order to evade the millisecond pulsar constraint on cosmic strings) are expected to be strongly type I

on flexicurity and its implications for labour market transitions, little attention has been paid to the views and experiences of the individuals concerned. The aim of this article is to connect the grand narrative with individual narratives about labour market transitions in the Danish flexicurity system....... On the basis of narrative interviews with skilled workers, this article explores how labour market transitions are experienced by the individual and the role played by national support structures in the individual narratives. The article shows how, for the individual, a transition may prove to be a valuable...... learning experience during which radical career decisions are taken, and how support structures may work to the detriment of such learning and of the principles behind flexicurity. The article points to a reconceptualisation of transitions as important learning opportunities during which (more) adequate...

Mood and narrative entwinement: some implications for educational practice.

Science.gov (United States)

Conroy, Sherrill A; Dobson, Stephen

2005-09-01

Moods are one way of existentially reading the authenticity of people and are entwined within any narrative. Attunement between narrative and its mood is crucial for understanding the implicit message of the narrator. Sometimes, a master narrative is interrupted by counternarratives, so that narrative recognition becomes problematic. People can disguise their existential state when narrating, but the mood discloses it nonetheless. The authors explore the relationship between mood and narrative, and how the two are connected with how a person acts authentically or inauthentically. They provide selected empirical examples of narratives from medical students to support their argument. The educational relevance of their discussion comprises the final section. Educators in any educational program must first reflect on, then make explicit the manner in which narrative and mood are used to communicate knowledge.

Before 2005, time accrued on the lung transplant waiting list counted towards who was next in line for a donor lung. Then in 2005 the lung allocation scoring system was implemented, which meant the higher the illness severity scores, the higher the priority on the transplant list. Little is known of the lung transplant candidates who were listed before 2005 and were caught in the transition when the lung allocation scoring system was implemented. A narrative analysis was conducted to explore the illness narratives of seven lung transplant candidates between 2006 and 2007. Arthur Kleinman's concept of illness narratives was used as a conceptual framework for this study to give voice to the illness narratives of lung transplant candidates. Results of this study illustrate that lung transplant candidates expressed a need to tell their personal story of waiting and to be heard. Recommendation from this study calls for healthcare providers to create the time to enable illness narratives of the suffering of waiting to be told. Narrative skills of listening to stories of emotional suffering would enhance how healthcare providers could attend to patients' stories and hear what is most meaningful in their lives.

We investigate the texture of fermion mass matrices in theories with partial unification (for example, SU(2) L x SU(2) R x SU(4) c ) at a scale of ∼ 10 12 GeV. Starting with the low energy values of the masses and the mixing angles, we find only two viable textures with at most four texture zeros. One of these corresponds to a somewhat modified Fritzsch textures. A theoretical derivation of these textures leads to new interesting relations among the masses and the mixing angles. 13 refs

Conclusions The information gleaned during open narratives was subject to inter-interviewer variability and contained a limited number of symptom indicators, suggesting that their use for assigning cause of death is questionable. However, they contained rich information on care-seeking, healthcare provision and social factors in the lead-up to death, which may be a valuable source of information for promoting accountable health services.

Adaptive Texture Synthesis for Large Scale City Modeling

Science.gov (United States)

Despine, G.; Colleu, T.

2015-02-01

Large scale city models textured with aerial images are well suited for bird-eye navigation but generally the image resolution does not allow pedestrian navigation. One solution to face this problem is to use high resolution terrestrial photos but it requires huge amount of manual work to remove occlusions. Another solution is to synthesize generic textures with a set of procedural rules and elementary patterns like bricks, roof tiles, doors and windows. This solution may give realistic textures but with no correlation to the ground truth. Instead of using pure procedural modelling we present a method to extract information from aerial images and adapt the texture synthesis to each building. We describe a workflow allowing the user to drive the information extraction and to select the appropriate texture patterns. We also emphasize the importance to organize the knowledge about elementary pattern in a texture catalogue allowing attaching physical information, semantic attributes and to execute selection requests. Roofs are processed according to the detected building material. Façades are first described in terms of principal colours, then opening positions are detected and some window features are computed. These features allow selecting the most appropriate patterns from the texture catalogue. We experimented this workflow on two samples with 20 cm and 5 cm resolution images. The roof texture synthesis and opening detection were successfully conducted on hundreds of buildings. The window characterization is still sensitive to the distortions inherent to the projection of aerial images onto the facades.

RAMESES publication standards: meta-narrative reviews

2013-01-01

Full Text Available Abstract Background Meta-narrative review is one of an emerging menu of new approaches to qualitative and mixed-method systematic review. A meta-narrative review seeks to illuminate a heterogeneous topic area by highlighting the contrasting and complementary ways in which researchers have studied the same or a similar topic. No previous publication standards exist for the reporting of meta-narrative reviews. This publication standard was developed as part of the RAMESES (Realist And MEta-narrative Evidence Syntheses: Evolving Standards project. The project's aim is to produce preliminary publication standards for meta-narrative reviews. Methods We (a collated and summarized existing literature on the principles of good practice in meta-narrative reviews; (b considered the extent to which these principles had been followed by published reviews, thereby identifying how rigor may be lost and how existing methods could be improved; (c used a three-round online Delphi method with an interdisciplinary panel of national and international experts in evidence synthesis, meta-narrative reviews, policy and/or publishing to produce and iteratively refine a draft set of methodological steps and publication standards; (d provided real-time support to ongoing meta-narrative reviews and the open-access RAMESES online discussion list so as to capture problems and questions as they arose; and (e synthesized expert input, evidence review and real-time problem analysis into a definitive set of standards. Results We identified nine published meta-narrative reviews, provided real-time support to four ongoing reviews and captured questions raised in the RAMESES discussion list. Through analysis and discussion within the project team, we summarized the published literature, and common questions and challenges into briefing materials for the Delphi panel, comprising 33 members. Within three rounds this panel had reached consensus on 20 key publication standards, with an

Full Text Available This paper demonstrates that digital tools provide opportunities for new storytelling techniques. To take full advantage of the new media resources and to establish an innovative news narrative structure, the existing research limit and the relationship between narrative and the media were examined. This paper progresses from a discussion on the narrative structure to how the plot of a story is influenced by its discourse, and then to how different media characteristics can change the structure and voice of the involved narrative. A new narrative structure that can be used to explore the hypertext and interactivity of Internet news is described. Finally, this paper discusses the cultivation of news storytelling in the digital age.

A through-process texture and anisotropy prediction for AA5182 sheet production from hot rolling through cold rolling and annealing is reported. Thermo-mechanical process data predicted by the finite element method (FEM) package T-Pack based on the software LARSTRAN were fed into a combination of physics based microstructure models for deformation texture (GIA), work hardening (3IVM), nucleation texture (ReNuc), and recrystallization texture (StaRT). The final simulated sheet texture was fed into a FEM simulation of cup drawing employing a new concept of interactively updated texture based yield locus predictions. The modelling results of texture development and anisotropy were compared to experimental data. The applicability to other alloys and processes is discussed.

Understanding personal narratives: an approach to practice.

Gaydos, H Lea

2005-02-01

This paper explores the need for and nature of personal narratives and their relevance to nursing practice. It proposes that the co-creative aesthetic process can be used to understand and co-create personal narratives through an emphasis on self-defining memories and metaphor. Many authors in nursing and other human sciences have recognized the need for and importance of personal narrative, its relationship to aesthetic knowing and its value in qualitative research and in practice. The role of memory and metaphor in the creation of meaning in personal narratives, however, has not been sufficiently explored in nursing literature. The nature of personal narrative is explored, focusing on the way meaning is created from self-defining memories using metaphor. Then, the importance of personal narratives in nursing practice is considered, followed by discussion about how meaning in personal narratives may be co-created between clients and nurses using an aesthetic process developed by the author. The co-creative aesthetic process is an example of nursing as art and can be used to co-create personal narratives in practice. The experience of co-creating a self story with a nurse can be healing, as the self story is heard by a caring person, memories are understood in new ways, and the self story is both confirmed and recreated.

Shape-Tailored Features and their Application to Texture Segmentation

KAUST Repository

Khan, Naeemullah

2014-04-01

Texture Segmentation is one of the most challenging areas of computer vision. One reason for this difficulty is the huge variety and variability of textures occurring in real world, making it very difficult to quantitatively study textures. One of the key tools used for texture segmentation is local invariant descriptors. Texture consists of textons, the basic building block of textures, that may vary by small nuisances like illumination variation, deformations, and noise. Local invariant descriptors are robust to these nuisances making them beneficial for texture segmentation. However, grouping dense descriptors directly for segmentation presents a problem: existing descriptors aggregate data from neighborhoods that may contain different textured regions, making descriptors from these neighborhoods difficult to group, leading to significant errors in segmentation. This work addresses this issue by proposing dense local descriptors, called Shape-Tailored Features, which are tailored to an arbitrarily shaped region, aggregating data only within the region of interest. Since the segmentation, i.e., the regions, are not known a-priori, we propose a joint problem for Shape-Tailored Features and the regions. We present a framework based on variational methods. Extensive experiments on a new large texture dataset, which we introduce, show that the joint approach with Shape-Tailored Features leads to better segmentations over the non-joint non Shape-Tailored approach, and the method out-performs existing state-of-the-art.

Mineralogical, textural, structural and geochemical aspects of Nakhlak lead mine, Isfahan

Directory of Open Access Journals (Sweden)

Mohammad Ali Jazi

2010-11-01

Full Text Available Nakhlak lead mine is located at the Nakhlak mountain 55 km NE of Anarak town in Isfahan province. The mineralogy is simple; galena and barite are the main primary minerals and cerussite is the main secondary mineral. Sphalerite, pyrite, chalcopyrite, tetrahedrite-tennantite and acanthite occur as minor and trace mineral inclusions in galena. Secondary minerals are anglesite, plattnerite, wulfenite and malachite. The host rock has undergone a pre-mineralization dolomitization process. Four types of dolomite have been identified which saddle dolomite is the most distinguished. Open space filling textures occur in the form of breccia, cockade, crustification and colloform. Analysis of the galena samples indicates presence of many trace elements in galena among which silver is the most important. Element pairs such as Ag-As, Zn-Cd, As-Cu and As-Sb are highly correlated. This correlation may be explained by the presence of inclusions. Ag-Sb-Bi ternary diagram indicates that galena samples from Nakhlak are rich in Ag and Sb and poor in Bi. Sb/Bi (3773 ratio in galena is suggestive of a low temperature of formation for the deposit. The Upper Cretaceous carbonate host rocks and their dolomitization, the stratabound and epigenetic mineralization, the absence of igneous activity, the open space filling texture, the simple mineralogy and geochemistry all point to a Mississippi valley type model for the Nakhlak Pb deposit.

TOPICAL REVIEW Textured silicon nitride: processing and anisotropic properties

Xinwen Zhu and Yoshio Sakka

2008-01-01

Full Text Available Textured silicon nitride (Si3N4 has been intensively studied over the past 15 years because of its use for achieving its superthermal and mechanical properties. In this review we present the fundamental aspects of the processing and anisotropic properties of textured Si3N4, with emphasis on the anisotropic and abnormal grain growth of β-Si3N4, texture structure and texture analysis, processing methods and anisotropic properties. On the basis of the texturing mechanisms, the processing methods described in this article have been classified into two types: hot-working (HW and templated grain growth (TGG. The HW method includes the hot-pressing, hot-forging and sinter-forging techniques, and the TGG method includes the cold-pressing, extrusion, tape-casting and strong magnetic field alignment techniques for β-Si3N4 seed crystals. Each processing technique is thoroughly discussed in terms of theoretical models and experimental data, including the texturing mechanisms and the factors affecting texture development. Also, methods of synthesizing the rodlike β-Si3N4 single crystals are presented. Various anisotropic properties of textured Si3 N4 and their origins are thoroughly described and discussed, such as hardness, elastic modulus, bending strength, fracture toughness, fracture energy, creep behavior, tribological and wear behavior, erosion behavior, contact damage behavior and thermal conductivity. Models are analyzed to determine the thermal anisotropy by considering the intrinsic thermal anisotropy, degree of orientation and various microstructure factors. Textured porous Si3N4 with a unique microstructure composed of oriented elongated β-Si3N4 and anisotropic pores is also described for the first time, with emphasis on its unique mechanical and thermal-mechanical properties. Moreover, as an important related material, textured α-Sialon is also reviewed, because the presence of elongated α-Sialon grains allows the production of textured �

Williams syndrome (WS) is a genetic disorder associated with intellectual disability and characterised by displaying an atypical neuropsychological profile, with peaks and valleys, where language skills seem better preserved than non-verbal intelligence. This study researches the narrative competence of nine Spanish-speaking adults with WS. Oral narratives were elicited from a silent film, and narrative coherence was analysed as a function of sequential order of the events narrated at three structure levels, while narrative cohesion was assessed through the frequency of use and type of discourse markers. WS subjects were able to remember a significant proportion of the events from the film, but coherence of narratives, i.e., sequential order of events, was more impaired. Consistently with their linguistic abilities, cohesion of narratives was better preserved, as they used discourse markers to introduce a high proportion of events. Construction of mental models of the narratives may be constrained in WS by non-verbal cognitive abilities, but narrative competence is also determined by textual pragmatic abilities to organize discourse, which should be addressed by specific intervention in narrative competence.

The perception of event structure in continuous activity is important for everyday comprehension. Although the segmentation of experience into events is a normal concomitant of perceptual processing, previous research has shown age differences in the ability to perceive structure in naturalistic activity, such as a movie of someone washing a car. However, past research has also shown that older adults have a preserved ability to comprehend events in narrative text, which suggests that narrative may improve the event processing of older adults. This study tested whether there are age differences in event segmentation at the intersection of continuous activity and narrative: narrative film. Younger and older adults watched and segmented a narrative film, The Red Balloon, into coarse and fine events. Changes in situational features, such as changes in characters, goals, and objects predicted segmentation. Analyses revealed little age-difference in segmentation behavior. This suggests the possibility that narrative structure supports event understanding for older adults.

2016-01-01

Full Text Available Hot stamping of high strength steels has been continuously developed in the automotive industry to improve mechanical properties and surface quality of stamped components. One of the main challenges faced by researchers and technicians is to improve stamping dies lifetime by reducing the wear caused by high pressures and temperatures present during the process. This paper analyzes the laser texturing of hot stamping dies and discusses how different surfaces textures influence the lubrication and wear mechanisms. To this purpose, experimental tests and numerical simulation were carried out to define the die region to be texturized and to characterize the textured surface topography before and after hot stamping tests with a 3D surface profilometer and scanning electron microscopy. Results showed that laser texturing influences the lubrication at the interface die-hot sheet and improves die lifetime. In this work, the best texture presented dimples with the highest diameter, depth, and spacing, with the surface topography and dimples morphology practically preserved after the hot stamping tests.

Effect of Mixing Ratio between Pork Loin and Chicken Breast on Textural and Sensory Properties of Emulsion Sausages

Science.gov (United States)

2014-01-01

This study is conducted to evaluate the effects of the mixing ratio between pork loin and chicken breast for textural and sensory properties of emulsion sausages. Meat homogenates are prepared by using five mixing ratios between pork loin and chicken breast (100:0, 70:30, 50:50, 30:70, and 0:100), and the emulsion sausages are also formulated with five mixing ratios. The additions of chicken breast increase the salt soluble protein solubility due to high pH levels of chicken breast, thereby resulting in the reduction of cooking losses. In addition, the apparent viscosity of meat homogenates increase with increasing amounts of chicken breast. In terms of emulsion sausages formulated with pork loin and chicken breast, the addition of chicken breast above 50% may contribute to a softer and more flexible texture of emulsion sausages. For sensory evaluations, an increase in the added amount of chicken breast contributes to a rich umami taste and deeper flavor within the emulsion sausages, resulting in the high overall acceptance score for the formulation of 0-30% pork loin and 70-100% chicken breast. Therefore, the optimal mixing ratios between pork loin and chicken breast are 0-30% and 70-100% for enhancing the textural and sensory properties of emulsion sausages. PMID:26760930

How do earthworms, soil texture and plant composition affect infiltration along an experimental plant diversity gradient in grassland?

Directory of Open Access Journals (Sweden)

Christine Fischer

Full Text Available BACKGROUND: Infiltration is a key process in determining the water balance, but so far effects of earthworms, soil texture, plant species diversity and their interaction on infiltration capacity have not been studied. METHODOLOGY/PRINCIPAL FINDINGS: We measured infiltration capacity in subplots with ambient and reduced earthworm density nested in plots of different plant species (1, 4, and 16 species and plant functional group richness and composition (1 to 4 groups; legumes, grasses, small herbs, tall herbs. In summer, earthworm presence significantly increased infiltration, whereas in fall effects of grasses and legumes on infiltration were due to plant-mediated changes in earthworm biomass. Effects of grasses and legumes on infiltration even reversed effects of texture. We propose two pathways: (i direct, probably by modifying the pore spectrum and (ii indirect, by enhancing or suppressing earthworm biomass, which in turn influenced infiltration capacity due to change in burrowing activity of earthworms. CONCLUSIONS/SIGNIFICANCE: Overall, the results suggest that spatial and temporal variations in soil hydraulic properties can be explained by biotic processes, especially the presence of certain plant functional groups affecting earthworm biomass, while soil texture had no significant effect. Therefore biotic parameters should be taken into account in hydrological applications.

Rapakivi texture formation via disequilibrium melting in a contact partial melt zone, Antarctica

Science.gov (United States)

Currier, R. M.

2017-12-01

In the McMurdo Dry Valleys of Antarctica, a Jurassic aged dolerite sill induced partial melting of granite in the shallow crust. The melt zone can be traced in full, from high degrees of melting (>60%) along the dolerite contact, to no apparent signs of melting, 10s of meters above the contact. Within this melt zone, the well-known rapakivi texture is found, arrested in various stages of development. High above the contact, and at low degrees of melting, K-feldspar crystals are slightly rounded and unmantled. In the lower half of the melt zone, mantles of cellular textured plagioclase appear on K-feldspar, and thicken towards the contact heat source. At the highest degrees of melting, cellular-textured plagioclase completely replaces restitic K-feldspar. Because of the complete exposure and intact context, the leading models of rapakivi texture formation can be tested against this system. The previously proposed mechanisms of subisothermal decompression, magma-mixing, and hydrothermal exsolution all fail to adequately describe rapakivi generation in this melt zone. Preferred here is a closed system model that invokes the production of a heterogeneous, disequilibrium melt through rapid heating, followed by calcium and sodium rich melt reacting in a peritectic fashion with restitic K-feldspar crystals. This peritectic reaction results in the production of plagioclase of andesine-oligoclase composition—which is consistent with not just mantles in the melt zone, but globally as well. The thickness of the mantle is diffusion limited, and thus a measure of the diffusive length scale of sodium and calcium over the time scale of melting. Thermal modeling provides a time scale of melting that is consistent with the thickness of observed mantles. Lastly, the distribution of mantled feldspars is highly ordered in this melt zone, but if it were mobilized and homogenized—mixing together cellular plagioclase, mantled feldspars, and unmantled feldspars—the result would be

Kruz'elová, M; Vratislav, S; Kalvoda, L; Dlouhá, M

2012-01-01

Neutron diffraction is a very powerful tool in texture analysis of zirconium based alloys used in nuclear technique. Textures of five samples (two rolled sheets and three tubes) were investigated by using basal pole figures, inversion pole figures, and ODF distribution function. The texture measurement was performed at diffractometer KSN2 on the Laboratory of Neutron Diffraction, Department of Solid State Engineering, Faculty of Nuclear Sciences and Physical Engineering, CTU in Prague. Procedures for studying textures with thermal neutrons and procedures for obtaining texture parameters (direct and inverse pole figures, three dimensional orientation distribution function) are also described. Observed data were processed by software packages HEXAL and GSAS. Our results can be summarized as follows: i) All samples of zirconium alloys show the distribution of middle area into two maxima in basal pole figures. This is caused by alloying elements. A characteristic split of the basal pole maxima tilted from the normal direction toward the transverse direction can be observed for all samples, ii) Sheet samples prefer orientation of planes (100) and (110) perpendicular to rolling direction and orientation of planes (002) perpendicular to normal direction, iii) Basal planes of tubes are oriented parallel to tube axis, meanwhile (100) planes are oriented perpendicular to tube axis. Level of resulting texture and maxima position is different for tubes and for sheets. The obtained results are characteristic for zirconium based alloys.

Formation of textured strontium titanate (STO) layers with large lateral grain size (0.2-1 {mu}m) and low X-ray reflectivity roughness ({approx} 1.36 nm) on Pt electrodes by industry proven atomic layer deposition (ALD) method is demonstrated. Sr(t-Bu{sub 3}Cp){sub 2}, Ti(OMe){sub 4} and O{sub 3} precursors at 250 Degree-Sign C were used to deposit Sr rich STO on Pt/Ti/SiO{sub 2}/Si Empty-Set 200 mm substrates. After crystallization post deposition annealing at 600 Degree-Sign C in air, most of the STO grains showed a preferential orientation of the {l_brace}001{r_brace} plane parallel to the substrate surface, although other orientations were also present. Cross sectional and plan view transmission electron microscopy and electron diffraction analysis revealed more than an order of magnitude larger lateral grain sizes for the STO compared to the underlying multicrystalline {l_brace}111{r_brace} oriented platinum electrode. The combination of platinum bottom electrodes with ALD STO(O{sub 3}) shows a promising path towards the formation of single oriented STO film. - Highlights: Black-Right-Pointing-Pointer Amorphous strontium titanate (STO) on platinum formed a textured film after annealing. Black-Right-Pointing-Pointer Single crystal domains in 60 nm STO film were 0.2-1 {mu}m wide. Black-Right-Pointing-Pointer Most STO grains were {l_brace}001{r_brace} oriented.

ADAPTIVE TEXTURE SYNTHESIS FOR LARGE SCALE CITY MODELING

Directory of Open Access Journals (Sweden)

G. Despine

2015-02-01

Full Text Available Large scale city models textured with aerial images are well suited for bird-eye navigation but generally the image resolution does not allow pedestrian navigation. One solution to face this problem is to use high resolution terrestrial photos but it requires huge amount of manual work to remove occlusions. Another solution is to synthesize generic textures with a set of procedural rules and elementary patterns like bricks, roof tiles, doors and windows. This solution may give realistic textures but with no correlation to the ground truth. Instead of using pure procedural modelling we present a method to extract information from aerial images and adapt the texture synthesis to each building. We describe a workflow allowing the user to drive the information extraction and to select the appropriate texture patterns. We also emphasize the importance to organize the knowledge about elementary pattern in a texture catalogue allowing attaching physical information, semantic attributes and to execute selection requests. Roofs are processed according to the detected building material. Façades are first described in terms of principal colours, then opening positions are detected and some window features are computed. These features allow selecting the most appropriate patterns from the texture catalogue. We experimented this workflow on two samples with 20 cm and 5 cm resolution images. The roof texture synthesis and opening detection were successfully conducted on hundreds of buildings. The window characterization is still sensitive to the distortions inherent to the projection of aerial images onto the facades.

Electrochemically grown rough-textured nanowires

Tyagi, Pawan; Postetter, David; Saragnese, Daniel; Papadakis, Stergios J.; Gracias, David H.

2010-01-01

Nanowires with a rough surface texture show unusual electronic, optical, and chemical properties; however, there are only a few existing methods for producing these nanowires. Here, we describe two methods for growing both free standing and lithographically patterned gold (Au) nanowires with a rough surface texture. The first strategy is based on the deposition of nanowires from a silver (Ag)-Au plating solution mixture that precipitates an Ag-Au cyanide complex during electrodeposition at low current densities. This complex disperses in the plating solution, thereby altering the nanowire growth to yield a rough surface texture. These nanowires are mass produced in alumina membranes. The second strategy produces long and rough Au nanowires on lithographically patternable nickel edge templates with corrugations formed by partial etching. These rough nanowires can be easily arrayed and integrated with microscale devices.

Forest texture is an intrinsic characteristic and an important visual feature of a forest ecological system. Full utilization of forest texture will be a great help in increasing the accuracy of forest classification based on remote sensed data. Taking Shangri-La as a study area, forest classification has been based on the texture. The results show that: (1) From the texture abundance, texture boundary, entropy as well as visual interpretation, the combination of Grayscale-gradient co-occurrence matrix and wavelet transformation is much better than either one of both ways of forest texture information extraction; (2) During the forest texture information extraction, the size of the texture-suitable window determined by the semi-variogram method depends on the forest type (evergreen broadleaf forest is 3×3, deciduous broadleaf forest is 5×5, etc.). (3)While classifying forest based on forest texture information, the texture factor assembly differs among forests: Variance Heterogeneity and Correlation should be selected when the window is between 3×3 and 5×5 Mean, Correlation, and Entropy should be used when the window in the range of 7×7 to 19×19 and Correlation, Second Moment, and Variance should be used when the range is larger than 21×21.

We evaluated the association between positron emission tomography (PET) textural features and glucose transporter 1 (GLUT1) expression level and further investigated the prognostic significance of textural features in lung adenocarcinoma. We evaluated 105 adenocarcinoma patients. We extracted texture-based PET parameters of primary tumors. Conventional PET parameters were also measured. The relationships between PET parameters and GLUT1 expression levels were evaluated. The association between PET parameters and overall survival (OS) was assessed using Cox's proportional hazard regression models. In terms of PET textural features, tumors expressing high levels of GLUT1 exhibited significantly lower coarseness, contrast, complexity, and strength, but significantly higher busyness. On univariate analysis, the metabolic tumor volume, total lesion glycolysis, contrast, busyness, complexity, and strength were significant predictors of OS. Multivariate analysis showed that lower complexity (HR=2.017, 95%CI=1.032-3.942, p=0.040) was independently associated with poorer survival. PET textural features may aid risk stratification in lung adenocarcinoma patients. Copyright© 2018, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.

The influence of phosphorus gettering is studied in this work applied to an acidic textured multicrystalline silicon substrate. The texturization was achieved with an HF/HNO{sub 3} solution leading to nanostructures on the silicon surface. It has been demonstrated in previous works that this textured surface decreases the reflectance on the solar cell and increases the surface area improving the photon collection and enhancing the short circuit current. The present study investigates the effect on the minority carrier lifetime of the phosphorous diffusion when it is carried out on this textured surface. The lifetime is measured by means microwave photoconductance decay and quasi steady state phototoconductance devices. The diffused textured wafers are used to fabricate solar cells and their electrical parameters are analyzed. (copyright 2011 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

SHAPE FROM TEXTURE USING LOCALLY SCALED POINT PROCESSES

Directory of Open Access Journals (Sweden)

Eva-Maria Didden

2015-09-01

Full Text Available Shape from texture refers to the extraction of 3D information from 2D images with irregular texture. This paper introduces a statistical framework to learn shape from texture where convex texture elements in a 2D image are represented through a point process. In a first step, the 2D image is preprocessed to generate a probability map corresponding to an estimate of the unnormalized intensity of the latent point process underlying the texture elements. The latent point process is subsequently inferred from the probability map in a non-parametric, model free manner. Finally, the 3D information is extracted from the point pattern by applying a locally scaled point process model where the local scaling function represents the deformation caused by the projection of a 3D surface onto a 2D image.

2017-01-01

Storytelling is an increasingly well recognised and valued platform to learn about the human experience within healthcare. Little is known however about how stories can enhance understanding in neonatal care, a specialised field offering rich opportunities for learning. This study focuses on the creation of stories based on the experiences of student nurses to inform teaching and learning strategies in the neonatal field. The study aimed to create stories from the narratives of student nurses working within the neonatal field and identify what key themes for learning emerged in order to develop a storytelling resource to share experiences with their peers. An interpretive, constructivist approach was used to collect, analyse and create stories from student nurse's experiences, in line with narrative inquiry. Six pre-registration children's nursing students were selected by purposive sampling. Interviews were undertaken within six weeks following placement completion in an agreed location. Narratives were obtained by semi-structured interviews. Narrative analysis and core story creation was undertaken to construct stories and key learning themes emerged which provided the pedagogical basis for subsequent digital resource development. Key themes emerged relating to the insight and observances of student nurses and the neonatal journey they had experienced, including the nature of neonatal care, experiences of the neonate and parents, the environment and their own learning transition. Preliminary peer evaluation of the storytelling resource revealed storytelling as an interesting and novel approach to teaching & learning, learning from ones' peers, preparation for practice and a valuable insight into a new specialist area. The study has value to teaching and learning by enabling an appreciation of how narrative can be used to portray the experiences of learners. Findings also support an approach to analysing narrative to create stories for learning and inform

A narrative analysis of helplessness in depression.

Science.gov (United States)

Vanheule, Stijn; Hauser, Stuart T

2008-12-01

The transcripts of semistructured clinical interviews with forty psychiatrically hospitalized adolescents were subjected to narrative analysis in an effort to map the logic of their explanations as they spontaneously talked about helplessness experiences, and to determine how helplessness is embedded in broader story lines. Three types of narrative composition were discerned, and are discussed by means of excerpts from the interviews. In a first and predominant type of narrative, a disturbing confrontation with another is pivotal: the other's intentions are obscure; this frightens the narrator, who does not know what to do. Helplessness arises as a direct result of not knowing how to manage the "unbearable riddle" of the other's intentions. In the second, more marginal type of narrative, helplessness is embedded in an account of emptiness and boredom. The protagonist relates enduring experiences of emptiness due to loss and the suffering consequent on it. In the third, also more marginal type of narrative, helplessness is framed in a context of failure: the protagonist adheres to strict standards, feels he or she has fallen short, and concludes that he or she is a failure. Only the first type of narrative is significantly related to the psychiatric diagnoses of mood disorder and major depression.

Narrative Based Medicine (NBM) can be defined as follows; a) It views the patient's illness as an unfolding story within the wider story of the patient's life and life-world; b) It acknowledges the patient as the narrator of the story and the subject of the tale; c) It recognizes that all medical theories, hypothesis and pathophysiologies as socially constructed narratives and accepts the coexistence of multiple different narratives; d) It regards the emergence of new stories from dialogue and discourse between patients and healthcare professionals as part of the treatment. Because psychiatry is the only area of specialist medicine where talking and listening are explicitly understood to be therapeutic, NBM can be adopted an effective perspective and method in psychiatry.

Control of crystallographic texture and surface morphology of Pt/Tio2 templates for enhanced PZT thin film texture.

Optimized processing conditions for Pt/TiO2/SiO2/Si templating electrodes were investigated. These electrodes are used to obtain [111] textured thin film lead zirconate titanate (Pb[ZrxTi1-x ]O3 0 ≤ x ≤ 1) (PZT). Titanium deposited by dc magnetron sputtering yields [0001] texture on a thermally oxidized Si wafer. It was found that by optimizing deposition time, pressure, power, and the chamber pre-conditioning, the Ti texture could be maximized while maintaining low surface roughness. When oxidized, titanium yields [100]-oriented rutile. This seed layer has as low as a 4.6% lattice mismatch with [111] Pt; thus, it is possible to achieve strongly oriented [111] Pt. The quality of the orientation and surface roughness of the TiO2 and the Ti directly affect the achievable Pt texture and surface morphology. A transition between optimal crystallographic texture and the smoothest templating surface occurs at approximately 30 nm of original Ti thickness (45 nm TiO2). This corresponds to 0.5 nm (2 nm for TiO2) rms roughness as determined by atomic force microscopy and a full-width at half-maximum (FWHM) of the rocking curve 0002 (200) peak of 5.5/spl degrees/ (3.1/spl degrees/ for TiO2). A Pb[Zr0.52Ti 0.48]O3 layer was deposited and shown to template from the textured Pt electrode, with a maximum [111] Lotgering factor of 87% and a minimum 111 FWHM of 2.4/spl degrees/ at approximately 30 nm of original Ti.

X-ray pole figure analysis was applied to study texture and deformation mechanism in pure and commercial polycrystalline yttrium on cold working. It was found that in cast yttrium the texture manifected itself weakly enough both for pure and commercial metal. Analysis of the data obtained made it possible to assert that cold deformation of pure yttrium in the initial stage occurred mainly by slip the role of which decreased at strains higher than 36%. The texture of heavily deformed commercial yttrium contained two components, these were an 'ideal' basic orientation and an axial one with the angle of inclination about 20 deg. Twinning mechanism was revealed to be also possible in commercial yttrium

This study explored relationships between perspective-taking, emotion understanding, and children's narrative abilities. Younger (23 5-/6-year-olds) and older (24 7-/8-year-olds) children generated fictional narratives, using a wordless picture book, about a frog experiencing jealousy. Children's emotion understanding was assessed through a standardized test of emotion comprehension and their ability to convey the jealousy theme of the story. Perspective-taking ability was assessed with respect to children's use of narrative evaluation (i.e., narrative coherence, mental state language, supplementary evaluative speech, use of subjective language, and placement of emotion expression). Older children scored higher than younger children on emotion comprehension and on understanding the story's complex emotional theme, including the ability to identify a rival. They were more advanced in perspective-taking abilities, and selectively used emotion expressions to highlight story episodes. Subjective perspective taking and narrative coherence were predictive of children's elaboration of the jealousy theme. Use of supplementary evaluative speech, in turn, was predictive of both subjective perspective taking and narrative coherence. ©2010 The British Psychological Society.

Fast Image Texture Classification Using Decision Trees

Thompson, David R.

Texture analysis would permit improved autonomous, onboard science data interpretation for adaptive navigation, sampling, and downlink decisions. These analyses would assist with terrain analysis and instrument placement in both macroscopic and microscopic image data products. Unfortunately, most state-of-the-art texture analysis demands computationally expensive convolutions of filters involving many floating-point operations. This makes them infeasible for radiation- hardened computers and spaceflight hardware. A new method approximates traditional texture classification of each image pixel with a fast decision-tree classifier. The classifier uses image features derived from simple filtering operations involving integer arithmetic. The texture analysis method is therefore amenable to implementation on FPGA (field-programmable gate array) hardware. Image features based on the "integral image" transform produce descriptive and efficient texture descriptors. Training the decision tree on a set of training data yields a classification scheme that produces reasonable approximations of optimal "texton" analysis at a fraction of the computational cost. A decision-tree learning algorithm employing the traditional k-means criterion of inter-cluster variance is used to learn tree structure from training data. The result is an efficient and accurate summary of surface morphology in images. This work is an evolutionary advance that unites several previous algorithms (k-means clustering, integral images, decision trees) and applies them to a new problem domain (morphology analysis for autonomous science during remote exploration). Advantages include order-of-magnitude improvements in runtime, feasibility for FPGA hardware, and significant improvements in texture classification accuracy.

The texture of the cold-drawn copper wire was investigated along the radius using electron backscatter diffraction. The complex fiber texture of the central region of the wire was considered as the rolling texture consisting of a set of preferred orientations. The texture of the periphery region was revealed to be similar to the shear texture. The orientation-dependent properties of the wire were proven to be determined by the texture of the near-surface layers.

Evolution of solidification texture during additive manufacturing

Wei, H. L.; Mazumder, J.; DebRoy, T.

2015-01-01

Striking differences in the solidification textures of a nickel based alloy owing to changes in laser scanning pattern during additive manufacturing are examined based on theory and experimental data. Understanding and controlling texture are important because it affects mechanical and chemical properties. Solidification texture depends on the local heat flow directions and competitive grain growth in one of the six preferred growth directions in face centered cubic alloys. Therefore, the heat flow directions are examined for various laser beam scanning patterns based on numerical modeling of heat transfer and fluid flow in three dimensions. Here we show that numerical modeling can not only provide a deeper understanding of the solidification growth patterns during the additive manufacturing, it also serves as a basis for customizing solidification textures which are important for properties and performance of components.

2017-01-01

Narrative research, an inclusive term for a range of methodologies, has rapidly become part of medical education scholarship. In this paper we identify narrative inquiry as a particular theoretical and methodological framework within narrative research and outline its characteristics. We briefly summarise how narrative research has been used in studying medical learners' identity making in medical education. We then turn to the uses of narrative inquiry in studying medical learners' professional identity making. With the turn to narrative inquiry, the shift is to thinking with stories instead of about stories. We highlight four challenges in engaging in narrative inquiry in medical education and point toward promising future research and practice possibilities. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

A Fourier-based textural feature extraction procedure

Science.gov (United States)

Stromberg, W. D.; Farr, T. G.

1986-01-01

A procedure is presented to discriminate and characterize regions of uniform image texture. The procedure utilizes textural features consisting of pixel-by-pixel estimates of the relative emphases of annular regions of the Fourier transform. The utility and derivation of the features are described through presentation of a theoretical justification of the concept followed by a heuristic extension to a real environment. Two examples are provided that validate the technique on synthetic images and demonstrate its applicability to the discrimination of geologic texture in a radar image of a tropical vegetated area.

fields and Maximum Entropy (FRAME) model [213, 214] is used for inpaining texture. We argue that many ’textures’ contain details that must be inpainted exactly. Simultaneous reconstruction of geometric structure and texture is a difficult problem, therefore, a two-phase reconstruction procedure...... is proposed. An inverse temperature is added to the FRAME model. In the first phase, the geometric structure is reconstructed by cooling the distribution, and in the second phase, the texture is added by heating the distribution.

Winning the Battle but Losing the War? Narrative and Counter-Narratives Strategy

Directory of Open Access Journals (Sweden)

Christian Leuprecht

2010-11-01

Full Text Available Since 9/11, intelligence and security services have become particularly concerned about radical ideologies and have looked for ways on how to counter them. One of the strategies has been to develop a counter-narrative. Some authors, including those of this article, are concerned that, in the marketplace of ideas, the West is losing market-share.[1] Communication failures with the Muslim world were cited in a report by a U.S. Department of Defence Advisory Committee as early as 2004.[2] The puzzle this article explores is why, having recognized the problem early on, the data suggest that further ground has since been lost. We posit the problem as having to shift the discourse from one focusing on a single counter-narrative to one of tailoring communications to target specific audiences. The article traces methodological and empirical shortcomings that are at the root of the problem and builds on these findings to develop a model to strategize about counter-narratives.

The misleading narrative of the canonical faculty productivity trajectory.

A scientist may publish tens or hundreds of papers over a career, but these contributions are not evenly spaced in time. Sixty years of studies on career productivity patterns in a variety of fields suggest an intuitive and universal pattern: Productivity tends to rise rapidly to an early peak and then gradually declines. Here, we test the universality of this conventional narrative by analyzing the structures of individual faculty productivity time series, constructed from over 200,000 publications and matched with hiring data for 2,453 tenure-track faculty in all 205 PhD-granting computer science departments in the United States and Canada. Unlike prior studies, which considered only some faculty or some institutions, or lacked common career reference points, here we combine a large bibliographic dataset with comprehensive information on career transitions that covers an entire field of study. We show that the conventional narrative confidently describes only one-fifth of faculty, regardless of department prestige or researcher gender, and the remaining four-fifths of faculty exhibit a rich diversity of productivity patterns. To explain this diversity, we introduce a simple model of productivity trajectories and explore correlations between its parameters and researcher covariates, showing that departmental prestige predicts overall individual productivity and the timing of the transition from first- to last-author publications. These results demonstrate the unpredictability of productivity over time and open the door for new efforts to understand how environmental and individual factors shape scientific productivity.

2016-06-01

Full Text Available In order to study the influence of the angle and arrangement forms of micro-grooves on the tribological performance of the contact surface, the finite element analysis software was used to simulate the grooved textures with different angles and arrangements. The YLP-20 laser processing system was used to process grooved texture on stainless steel disk surfaces, and the Tribometer (UMT-2 was also used to conduct tribological test under the condition of rotation. The results show that the numerical simulation values are basically consistent with experimental results of grooved textures, and the tribological performance of the friction pairs with textures is also improved. The grooved textures with different angles and arrangement forms have different influence on tribological performance of friction pairs. When the friction velocity is less than 300r/min, the parallel texture with 0° has smaller friction coefficients. While the friction velocity is larger than 300r/min, the parallel texture with 90° has a better ability of reducing friction. Therefore, different grooved textures should be chosen according to operation conditions.

Magdaléna Lacko - Bartošová

2013-02-01

Full Text Available At present, there are limited and incomplete data on the ability of spelt to produce alimentary pasta of suitable quality. Noodles are traditional cereal-based food that is becoming increasingly popular worldwide because of its convenience, nutritional qualities, and palatability. It is generally accepted that texture is the main criterion for assessing overall quality of cooked noodles. We present selected indicators of noodle texture of three spelt cultivars – Oberkulmer Rotkorn, Rubiota and Franckenkorn grown in an ecological system at the locality of Dolna Malanta near Nitra. A texture analyzer TA.XT PLUS was used to determine cooked spelt wheat noodle firmness (N (AACC 66-50. The texture of cooked spelt wheat noodles was expressed also as elasticity (N and extensibility (mm. Statistical analysis showed significant influence of the variety and year of growing on the firmness, elasticity and extensibility of cooked noodles. The wholemeal spelt wheat noodles were characterized with lower cutting firmness than the flour noodles. Flour noodles were more tensile than wholemeal noodles. The best elasticity and extensibility of flour noodles was found in noodles prepared from Rubiota however from wholemeal noodles it was Oberkulmer Rotkorn. Spelt wheat is suitable for noodle production, however also here it is necessary to differentiate between varieties. According to achieved results, wholemeal noodles prepared from Oberkulmer Rotkorn can be recommended for noodle industry due to their consistent structure and better texture quality after cooking.

Full Text Available Research on narrative persuasion has yet to investigate whether this process influences behavior. The current study explored whether: 1 a narrative could persuade participants to donate to a charity, a prosocial, behavioral decision; 2 psychophysiological metrics can delineate the differences between donation/non-donation behaviors; and 3 donation behavior can be correlated with measures of psychophysiology, self-reported reactions to the narrative, and intrinsic characteristics. Participants (n = 49 completed personality/disposition questionnaires, viewed one of two versions of a narrative while EEG and ECG were recorded, completed a questionnaire regarding their reactions to the narrative, and were given an opportunity to donate to a charity related to the themes of the narrative. Results showed that 1 34.7% of participants donated; 2 psychophysiological metrics successfully delineated between donation behaviors and the effects of narrative version; and 3 psychophysiology and reactions to the narrative were better able to explain the variance (88% and 65%, respectively in the amount donated than all 3 metrics combined as well as any metric alone. These findings demonstrate the promise of narrative persuasion for influencing prosocial, behavioral decisions. Our results also illustrate the utility of the previously stated metrics for understanding and possibly even manipulating behaviors resulting from narrative persuasion.

Texture analysis using Gabor wavelets

Naghdy, Golshah A.; Wang, Jian; Ogunbona, Philip O.

1996-04-01

Receptive field profiles of simple cells in the visual cortex have been shown to resemble even- symmetric or odd-symmetric Gabor filters. Computational models employed in the analysis of textures have been motivated by two-dimensional Gabor functions arranged in a multi-channel architecture. More recently wavelets have emerged as a powerful tool for non-stationary signal analysis capable of encoding scale-space information efficiently. A multi-resolution implementation in the form of a dyadic decomposition of the signal of interest has been popularized by many researchers. In this paper, Gabor wavelet configured in a 'rosette' fashion is used as a multi-channel filter-bank feature extractor for texture classification. The 'rosette' spans 360 degrees of orientation and covers frequencies from dc. In the proposed algorithm, the texture images are decomposed by the Gabor wavelet configuration and the feature vectors corresponding to the mean of the outputs of the multi-channel filters extracted. A minimum distance classifier is used in the classification procedure. As a comparison the Gabor filter has been used to classify the same texture images from the Brodatz album and the results indicate the superior discriminatory characteristics of the Gabor wavelet. With the test images used it can be concluded that the Gabor wavelet model is a better approximation of the cortical cell receptive field profiles.

Full text: Texturing in ferroelectric ceramics has played an important role in the enhancement of their piezoelectric properties. Common methods for ceramic texturing are hot pressing and template grain ground; nevertheless, the needed facilities to apply hot pressing and the processing of single crystal make the texture of ceramics expensive and very difficult. In this study, a novel method was investigated to obtain highly textured lead-free ceramics. A (K 0.5 Na 0.5 ) 0.97 Li 0. 0 3 Nb 0.8 Ta 0. 2 matrix (KNLNT), with CuO excess was sintered between 1070 and 1110 °C following a solid state reaction procedure. The CuO excess promotes liquid phase formation and a partial melting of the material. XRD patterns showed the intensity of (100) family peaks became much stronger with the increasing of sintering temperature and CuO. In addition, Lotgering factor was calculated and exhibited a texture degree between 40 % and 70 % for sintered samples having 13 and 16 wt. % CuO, respectively. These, highly textured ceramics, with adequate cut, can be used as substitutes single crystals for texturing of KNN-based lead-free ceramics. (author)

Distinctive longitudinal narrative data, collected during a critical 18-year period in the history of the HIV epidemic, offer a unique opportunity to examine how young Africans are making sense of evolving developments in HIV prevention and treatment. More than 200,000 young people from across sub-Saharan Africa took part in HIV-themed scriptwriting contests held at eight discrete time points between 1997 and 2014, creating more than 75,000 narratives. This article describes the data reduction and management strategies developed for our cross-national and longitudinal study of these qualitative data. The study aims to inform HIV communication practice by identifying cultural meanings and contextual factors that inform sexual behaviors and social practices, and also to help increase understanding of processes of sociocultural change. We describe our sampling strategies and our triangulating methodologies, combining in-depth narrative analysis, thematic qualitative analysis, and quantitative analysis, which are designed to enable systematic comparison without sacrificing ethnographic richness.

Fe-6.5 wt% Si steel hot bands with different initial grain size and texture were obtained through different annealing treatment. These bands were then warm rolled and annealed. An analysis on the evolution of microstructure and texture, particularly the formation of recrystallization texture was studied. The results indicated that initial grain size and texture had a significant effect on texture evolution and magnetic properties. Large initial grains led to coarse deformed grains with dense and long shear bands after warm rolling. Such long shear bands resulted in growth advantage for {1 1 3} 〈3 6 1〉 oriented grains during recrystallization. On the other hand, sharp {11 h} 〈1, 2, 1/h〉 (α∗-fiber) texture in the coarse-grained sample led to dominant {1 1 2} 〈1 1 0〉 texture after warm rolling. Such {1 1 2} 〈1 1 0〉 deformed grains provided massive nucleation sites for {1 1 3} 〈3 6 1〉 oriented grains during subsequent recrystallization. These {1 1 3} 〈3 6 1〉 grains were confirmed to exhibit an advantage on grain growth compared to γ-fiber grains. As a result, significant {1 1 3} 〈3 6 1〉 texture was developed and unfavorable γ-fiber texture was inhibited in the final annealed sheet. Both these aspects led to superior magnetic properties in the sample with largest initial grain size. The magnetic induction B8 was 1.36 T and the high frequency core loss P10/400 was 17.07 W/kg.

Narrative self-constitution and vulnerability to co-authoring.

Science.gov (United States)

McConnell, Doug

2016-02-01

All people are vulnerable to having their self-concepts shaped by others. This article investigates that vulnerability using a theory of narrative self-constitution. According to narrative self-constitution, people depend on others to develop and maintain skills of self-narration and they are vulnerable to having the content of their self-narratives co-authored by others. This theoretical framework highlights how vulnerability to co-authoring is essential to developing a self-narrative and, thus, the possibility of autonomy. However, this vulnerability equally entails that co-authors can undermine autonomy by contributing disvalued content to the agent's self-narrative and undermining her authorial skills. I illustrate these processes with the first-hand reports of several women who survived sexual abuse as children. Their narratives of survival and healing reveal the challenges involved in (re)developing the skills required to manage vulnerability to co-authoring and how others can help in this process. Finally, I discuss some of the implications of co-authoring for the healthcare professional and the therapeutic relationship.

Narrative and natural history in the eighteenth century.

Science.gov (United States)

Terrall, Mary

2017-04-01

In the eighteenth century, natural histories of animals incorporated narratives about animal behaviour and narratives of discovery and experimentation. Naturalists used first-person accounts to link the stories of their scientific investigations to the stories of the animal lives they were studying. Understanding nature depended on narratives that shifted back and forth in any given text between animal and human, and between individual cases and generalizations about species. This paper explores the uses of narrative through examples from the work of René-Antoine Ferchault de Réaumur and Abraham Trembley. In all cases, narrative took the genre of natural history well beyond straightforward description and classification. Prose accounts of insect actions and mechanisms worked in tandem with visual narratives embedded in the accompanying illustrations, where artists developed strategies for representing sequences of minute changes over time. By throwing into relief the narrative sections of natural histories, the examples considered here expose the role played by these tales of encounters with the insect world in the making of natural historical knowledge.

2013-01-01

Full Text Available A story is one of the forms of human communication, and one of the oldest ways of understanding the world and exchanging knowledge. The story is told through words, images and movement, and therefore the phenomenon of narration cannot be limited to verbal expression only. One can narrate about real or imaginary events in order to convey a message, provide knowledge or entertainment, and also to create an art form as well as achieve aesthetic communication. The process by means of which the inner world is built within a literary work is certainly the story or narrative. Modern theory of narration enumerates a number of forms of narration indifferent media: in folklore and art, oral or written linguistic narrative form, in pantomime, picture, vitrage, and film. This paper discusses various contemporary narratological ideas.

Methods A total of 19 patients having NHL with an evaluable lymphoma lesion were scanned at three imaging timepoints with 1.5T device during clinical treatment evaluation. Texture characteristics of images were analyzed and classified with MaZda application and statistical tests. Results NHL tissue MRI texture imaged before treatment and under chemotherapy was classified within several subgroups, showing best discrimination with 96% correct classification in non-linear discriminant analysis of T2-weighted images. Texture parameters of MRI data were successfully tested with statistical tests to assess the impact of the separability of the parameters in evaluating chemotherapy response in lymphoma tissue. Conclusion Texture characteristics of MRI data were classified successfully; this proved texture analysis to be potential quantitative means of representing lymphoma tissue changes during chemotherapy response monitoring.

Texture of altered layers issued from glass corrosion

Phalippou, J.; Woignier, Th.; Ayral, A.

1997-01-01

The layers which develop at the glass surface subjected to water corrosion depend on a collection of interacting parameters. Such a material can be studied using techniques which have been previously demonstrated as suitable for gels. A detailed description of the behaviour of gels under measurements is given. Investigations show that to really know the texture both mechanical properties and permeability must be known. Different experiments are reported. They give a rough estimate of the altered layer texture. Results coming from different techniques are compared and in a few cases are used to estimate additional textural information. Finally we put an insight into the nature and consequently to the texture evolution of the layer as the corrosion proceeds. (authors)

columnar and equiaxial crystallization. According to the obtained results, the formation of the orbicular granitoid of Caldera may have initiated 1) during the generation of a magmatic fracture in the crystallization front of the Relincho pluton, where the water released by the host crystal mush was dissolved in the new batch of dioritic magma. 2) The high influx of water-rich liquids induced superheating conditions in the newly intruding magma that became a depolymerized liquid, where the only solid particules were the small irregular fragments of the host mush dragged from the fracture walls. 3) Volatile exsolution promoted crystallization under undercooling conditions. 4) Undercooling and nucleation around the core (cold germs) involved the physical and geochemical fractionation between two sub-systems: a gabbroic sub-system that comprises the solid paragénesis with a residual water-rich liquid and a granodioritic sub-system. 5) The orbicules, including core and inner shell, behaved as viscous bodies (crystals + residual liquid) floating in the granodioritic magma. 6) Higher undercooling rates occurred at the starting stage, close to the liquidus, promoting columnar crystallization around the cores and formation of the shells. Conversely, in the granodioritic matrix sub-system, equiaxial crystallization was promoted by low relative crystallization rates. 7) The rest of the crystallization process evolved later in the outer shell and the matrix, as suggested by the poikilitic textures observed in both sides of the orbicule contact, and under conditions close to the solidus of both sub-systems (shell and matrix). The water-rich residual liquid expelled during the orbicular shell crystallization was mingled with the partially crystallized matrix magma, generating the pegmatitic domains with large Kfs megacrysts.

Narrative environments and the capacity of disability narratives to motivate leisure-time physical activity among individuals with spinal cord injury.

Perrier, Marie-Josée; Smith, Brett M; Latimer-Cheung, Amy E

2013-01-01

Few individuals with spinal cord injury (SCI) engage in the recommended amount of leisure time physical activity (LTPA). Yet little is known about how, and why, active individuals engage in specific types of LTPA. This study explored how a unique narrative environment and disability narratives motivated individuals with SCI to engage in LTPA. Fourteen individuals with SCI from a physical activity program participated in approximately hour-long interviews. Interviews were then subjected to a narrative analysis. Individuals who used a restitution narrative (n = 6) were motivated to engage in functional LTPA because of the desire to maintain the body and restore the past self. The individual who used the chaos narrative (n = 1) preferred solitary LTPA as exposure to others with SCI was a constant reminder of the lost, pre-injury self. Individuals who used a quest narrative (n = 7) explored LTPA options that fit with their interests; these individuals were open to new types of LTPA, such as sport and outdoor recreation. The plot of three disability narratives can all motivate the pursuit of LTPA; however, not all types of LTPA are seen as equal. LTPA interventions can be enhanced through the lessons learned from this unique type of environment. Despite individuals' views about their disability, they can still be motivated to engage in routine LTPA. Different theoretical determinants, such as health or social benefits, hold different relevance for LTPA among individuals with differing disability narratives. The environment provided by practitioners can therefore elicit some stories of SCI while stifling others. Open narrative environment will attract individuals to listen and maintain involvement in LTPA.

This region is then encoded using texture features based on the Laplacian-of-Gaussian (LoG filter, discrete wavelets (DW and gray level co-occurrence matrices (GLCM. To assess the significance of textural differences between PT types, a statistical analysis based on the Kruskal-Wallis test is performed. The usefulness of texture features is then evaluated quantitatively in terms of their ability to predict PT types using various classifier models.Preliminary results show significant texture differences between PT types, for all texture features (p-value < 0.01. Individually, GLCM texture features outperform LoG and DW features in terms of PT type prediction. However, a higher performance can be achieved by combining all texture features, resulting in a mean classification accuracy of 98.92%, sensitivity of 98.12%, and specificity of 99.67%.These results demonstrate the efficiency and effectiveness of combining multiple texture features for characterizing the continuum of CRC and discriminating between pathological tissues in multispectral images.

The textures produced in zirconium by the extrusion at 730 deg C of a cylindrical billet in the form of a plate having a rectangular cross-section, have been studied by the Schulz method using an isotropic standard.

1977-01-01

An electron-bombardment Hg ion thruster was used as an ion source to texture surfaces of materials used to make orthopedic and/or dental prostheses or implants. The materials textured include 316 stainless steel, titanium-6% aluminum, 4% vanadium, and cobalt-20% chromium, 15% tungsten. To determine the effect of ion texturing on the ultimate strength and yield strength, stainless steel and Co-Cr-W alloy samples were tensile tested to failure. Three types of samples of both materials were tested. One type was ion-textured (the process also heats each sample to 300 C), another type was simply heated to 300 C in an oven, and the third type was untreated. Stress-strain diagrams, 0.2% offset yield strength data, total elongation data, and area reduction data are presented. Fatigue specimens of ion textured and untextured 316 stainless steel and Ti-6% Al-4% V were tested. Included as an ion textured sample is a Ti-6% Al-4% V sample which was ion machined by means of Ni screen mask so as to produce an array of 140 mu m x 140 mu m x 60 mu m deep pits. Scanning electron microscopy was used to characterize the ion textured surfaces.

Temperature dependences of piezoelectric properties were studied for h001i textured ceramics of bismuth layer-structured ferroelectrics, SrBi(2)Nb(2)O(9) (SBN). The textured ceramics with varied orientation degrees were fabricated by templated, grain-growth method, and the temperature dependences of resonance frequency were estimated. Excellent temperature stability of resonance frequency was obtained for the 76% textured ceramics. The resonance frequency of the 76% textured specimens varied almost linearly over a wide temperature range. Therefore, the variation was slight, even in a high temperature region above 150 degrees C. Temperature stability of a quartz crystal oscillator is generally higher than that of a ceramic resonator around room temperature. The variation of resonance frequency for the 76% textured SrBi(2)Nb(2)O(9) was larger than that of oscillation frequency for a typical quartz oscillator below 150 degrees C also in this study. However, the variation of the textured SrBi(2)Nb(2)O(9) was smaller than that of the quartz oscillator over a wide temperature range from -50 to 250 degrees C. Therefore, textured SrBi(2)Nb(2)O(9) ceramics is a major candidate material for the resonators used within a wide temperature range.

Child, parent, and parent-child emotion narratives: implications for developmental psychopathology.

Science.gov (United States)

Oppenheim, David

2006-01-01

Studies using narratives with children and parents offer ways to study affective meaning-making processes that are central in many theories of developmental psychopathology. This paper reviews theory regarding affective meaning making, and argues that narratives are particularly suited to examine such processes. The review of narrative studies and methods is organized into three sections according to the focus on child, parent, and parent-child narratives. Within each focus three levels of analysis are considered: (a) narrative organization and coherence, (b) narrative content, and (c) the behavior/interactions of the narrator(s). The implications of this research for developmental psychopathology and clinical work are discussed with an emphasis on parent-child jointly constructed narratives as the meeting point of individual child and parent narratives.

2010-03-01

Dairy proteins are amenable to structural modifications induced by high temperature, shear, and moisture; in particular, whey proteins can change conformation to new unfolded states. The change in protein state is a basis for creating new foods. The dairy products, nonfat dried milk (NDM), whey protein concentrate (WPC), and whey protein isolate (WPI) were modified using a twin-screw extruder at melt temperatures of 50, 75, and 100 degrees C, and moistures ranging from 20 to 70 wt%. Viscoelasticity and solubility measurements showed that extrusion temperature was a more significant (P extruded dairy protein ranged from rigid (2500 N) to soft (2.7 N). Extruding at or above 75 degrees C resulted in increased peak force for WPC (138 to 2500 N) and WPI (2.7 to 147.1 N). NDM was marginally texturized; the presence of lactose interfered with its texturization. WPI products extruded at 50 degrees C were not texturized; their solubility values ranged from 71.8% to 92.6%. A wide possibility exists for creating new foods with texturized dairy proteins due to the extensive range of states achievable. Dairy proteins can be used to boost the protein content in puffed snacks made from corn meal, but unmodified, they bind water and form doughy pastes with starch. To minimize the water binding property of dairy proteins, WPI, or WPC, or NDM were modified by extrusion processing. Extrusion temperature conditions were adjusted to 50, 75, or 100 degrees C, sufficient to change the structure of the dairy proteins, but not destroy them. Extrusion modified the structures of these dairy proteins for ease of use in starchy foods to boost nutrient levels.

The Heeger & Bergen Pyramid Based Texture Synthesis Algorithm

Thibaud Briand

2014-11-01

Full Text Available This contribution deals with the Heeger-Bergen pyramid-based texture analysis/synthesis algorithm. It brings a detailed explanation of the original algorithm tested on many characteristic examples. Our analysis reproduces the original results, but also brings a minor improvement concerning non-periodic textures. Inspired by visual perception theories, Heeger and Bergen proposed to characterize a texture by its first-order statistics of both its color and its responses to multiscale and multi-orientation filters, namely the steerable pyramid. The Heeger-Bergen algorithm consists in the following procedure: starting from a white noise image, histogram matchings are performed to the noise alternatively in both the image domain and steerable pyramid domain, so that the corresponding histograms match the ones of the input texture.

Narrative Construction, Social Perceptions, and the Situation Model.

Science.gov (United States)

Costabile, Kristi A

2016-05-01

The present investigation examined how three salient features of narrative thinking (situation model construction, linguistic concreteness, and perspective-taking) influenced the social inference process. Results of four experiments indicated that compared with those given other objectives, perceivers given narrative objectives were: (a) more likely to make situation rather than trait attributions for observed behaviors (Experiment 1), (b) less likely to make implicit trait inferences (Experiment 2), and (c) less likely to rely on behavior valence when making evaluative judgments (Experiment 4). Linguistic analyses indicated that narrative construction consistently entailed the creation of situation models of events and linguistic concreteness, but only situation model creation mediated the relationship between narrative and inferences. Experiment 3 confirmed the mediating role of situation models: Perceivers with narrative objectives made trait inferences only when behaviors were inconsistent with contextual information. The role of these core narrative features on social perceptions is discussed. © 2016 by the Society for Personality and Social Psychology, Inc.

Cloud field classification based on textural features

Sengupta, Sailes Kumar

1989-01-01

An essential component in global climate research is accurate cloud cover and type determination. Of the two approaches to texture-based classification (statistical and textural), only the former is effective in the classification of natural scenes such as land, ocean, and atmosphere. In the statistical approach that was adopted, parameters characterizing the stochastic properties of the spatial distribution of grey levels in an image are estimated and then used as features for cloud classification. Two types of textural measures were used. One is based on the distribution of the grey level difference vector (GLDV), and the other on a set of textural features derived from the MaxMin cooccurrence matrix (MMCM). The GLDV method looks at the difference D of grey levels at pixels separated by a horizontal distance d and computes several statistics based on this distribution. These are then used as features in subsequent classification. The MaxMin tectural features on the other hand are based on the MMCM, a matrix whose (I,J)th entry give the relative frequency of occurrences of the grey level pair (I,J) that are consecutive and thresholded local extremes separated by a given pixel distance d. Textural measures are then computed based on this matrix in much the same manner as is done in texture computation using the grey level cooccurrence matrix. The database consists of 37 cloud field scenes from LANDSAT imagery using a near IR visible channel. The classification algorithm used is the well known Stepwise Discriminant Analysis. The overall accuracy was estimated by the percentage or correct classifications in each case. It turns out that both types of classifiers, at their best combination of features, and at any given spatial resolution give approximately the same classification accuracy. A neural network based classifier with a feed forward architecture and a back propagation training algorithm is used to increase the classification accuracy, using these two classes

Full Text Available The goal of this article is to introduce activity systems as a methodological tool in narrative inquiry to gain a holistic understanding of socially shared experiences from an examination of documents. The research question was how can qualitative researchers use activity systems as a tool for engaging in narrative inquiry of socially shared experiences to uncover new meanings by constructing a story? In this article, we share a sample analysis of our experience relying on documents and media as a form of narrative to begin to understand the socially shared human activity associated with net neutrality and its potential impact on U.S. residents. We end this article with reflections of lessons learned from our activity systems guided story construction process.

Poetics of Narrative in Antoine Volodine’s Novels

Directory of Open Access Journals (Sweden)

Victoriya Chub

2017-11-01

Full Text Available Antoine Volodine is reputed for inventing new forms in the French literature at the turn of XX–XXI centuries. Our study is dedicated to Volodine’s narrative structure, i.e. the stratification of narrative instances, the depersonalization of narrator and characters, the metanarrativization of story. Antoine Volodine creates a fictional world of uncertain characters floating between life and death and telling their stories in polyphonic voices. First, our study revealed the lack of demarcation between “I” and “we” and the blend of narrative levels created by ambivalent voices merging into a single “post-exotic horn”. Second, we discovered that metatextual comments and narrative figures of “mise en abyme” and metalepsis help to “alienate” the text and dramatize the relations between the author and readers. As a result, a specific “textual fiction” is being created to embody philosophical problems in Volodine’s meta-utopic novels. Finally, the research determined a set of poetical dominants typical for Volodine’s novels: the interference of homo- and heterodiegetic narrator instances, the uncertain nature of narrators and characters, the polyphonic character of voices as well as metatextual and transgressive structures. It was concluded that the revealed poetical dominants are not only a part of the literary game, but a specific way to represent the speech act. Antoine Volodine’s multilevel narrators share common mental pictures that show the experience of defeat, marginalization and imprisonment. The specific narrative structure helps the writer to create the effect of ambiguity and vagueness, adds a bit of doubt in the act of perception of his novels, updates the metaphysical perspective of the postmodern anti-utopia.

Texture collapse

Prokopec, T.; Sornborger, A.; Brandenberger, R.H.

1992-01-01

We study single-texture collapse using a leapfrog discretization method on a 30x30x30 spatial lattice. We investigate the influence of boundary conditions, physical size of the lattice, type of space-time background (flat, i.e., nonexpanding, vs radiation-dominated and matter-dominated universes), and spatial distribution of the initial texture configuration on collapse time and critical winding. For a spherically symmetric initial configuration of size equal to the horizon size on a lattice containing 12 (30) horizon volumes, the critical winding is found to be 0.621±0.001 (0.602±0.003) (flat case), 0.624±0.002 (0.604±0.005) (radiation era), 0.628±0.002 (0.612±0.003) (matter era). The larger the physical size of the lattice (in units of the horizon size), the smaller is the critical winding, and in the limit of an infinite lattice, we argue that the critical winding approaches 0.5. For radially asymmetric cases, contraction of one axis ( /Ipancake case) slightly reduces collapse time and critical winding, and contraction of two axes (d/Icigar case) reduces collapse time and critical winding significantly

Texture and anisotropy in the bismuth sodium titanate system

Science.gov (United States)

Fancher, Christoher M.

Bi0.5Na0.5TiO3 has received interest as a potential replacement for lead containing ferroelectrics. However, the piezoelectric response of pure Bi0.5Na0.5TiO 3 does not compare to the strong piezoelectric response of lead based piezoelectrics. To increase the piezoelectric response, Bi0.5Na 0.5TiO3 has been alloyed with BaTiO3 and K 0.5Na0.5NbO3. Another route to enhance the response is to take advantage of the anisotropic properties by inducing a preferred crystallographic orientation. Both routes were used to investigate the effect a crystallographic texture has on the strain response of Bi0.5Na 0.5TiO3-based ceramics. A crystallographic texture was induced by templated grain growth of pure phase Bi0.5Na0.5TiO3 templates using the tape casting method to orient template particles relative to the tape cast normal. Sintered Bi0.5Na0.5TiO3-based materials developed a strong (00l)pc fiber texture relative to the tape cast normal, with no preferential alignment relative to the tape cast plane. Textured Bi0.5Na0.5TiO3-(5)BaTiO3 showed a piezoelectric response of 245 pC/N, a better than 50% enhancement from the 150 pC/N response of randomly oriented samples. The Bi0.5Na0.5TiO3-(5)BaTiO3-(2)K 0.5Na0.5NbO3 (x,y) system has been shown to undergo electric-field-induced phase transformation from a pseudocubic to polar phase. For (7,2) a strong 8.7 multiples of a random distribution (MRD) crystallographic texture increased the macroscopic strain response by 50%. Applying the electric field perpendicular to the fiber texture axis reduces the macroscopic strain response of textured (7,2) by 17%. The affect field direction has on the electric-field-induced phase transformations of textured (7,2) was investigated using in situ electric field dependent diffraction. In situ diffraction data showed the high strain response of textured (7,2) can be attributed to a reversible pseudocubic to tetragonal transformation. The field-induced tetragonal phase nucleates preferentially with a

The formation of in-plane texture via ion bombardment of uniaxially textured metal films was investigated. In particular, selective grain Ar ion beam etching of uniaxially textured (0 0 1) Ni was used to achieve in-plane aligned Ni grains. Unlike conventional ion beam assisted deposition, the ion beam irradiates the uniaxially textured film surface with no impinging deposition flux. The initial uniaxial texture is established via surface energy minimization with no ion irradiation. Within this sequential texturing method, in-plane grain alignment is driven by selective etching and grain overgrowth. Biaxial texture was achieved for ion beam irradiation at elevated temperature.

Next, we extend the volume rendering pipeline by creating a transfer function which yields not only color and opacity from the input intensity, but also texture coordinates for our synthesized 3D texture. Thus, we add texture to the volume rendered images....... This method is applied to a high quality visualization of a pig carcass, where samples of meat, bone, and fat have been used to produce the anisotropic 3D textures....

The architecture of visual narrative comprehension: the interaction of narrative structure and page layout in understanding comics.

Cohn, Neil

How do people make sense of the sequential images in visual narratives like comics? A growing literature of recent research has suggested that this comprehension involves the interaction of multiple systems: The creation of meaning across sequential images relies on a "narrative grammar" that packages conceptual information into categorical roles organized in hierarchic constituents. These images are encapsulated into panels arranged in the layout of a physical page. Finally, how panels frame information can impact both the narrative structure and page layout. Altogether, these systems operate in parallel to construct the Gestalt whole of comprehension of this visual language found in comics.

A Narrative Criticism of Lifestyle Reality Programs

Directory of Open Access Journals (Sweden)

Travis Loof

2015-07-01

Full Text Available This article seeks to understand and explain the relationship between lifestyle reality television programs and consumers. Specifically, this article outlines this relationship from a critical narrative perspective by interrogating two common story structures within lifestyle reality programming. By analyzing these narratives, conclusions are drawn about the role of story in consumer behavior. Additionally, this article argues that through the combination of the rhetorical situation of the housing collapse and narrative storytelling, consumers are taught how to perceive and interact when considering the purchase of a house. Finally, this article synthesizes Social Cognitive theory (Bandura, 1986 in conjunction with Narrative theory (Fisher, 1984 to explore how rhetorical criticism can use social science to better understand lived, mediated, experience.

Landscapes of Memories: Visual and Spatial Dimensions of Hajja's Narrative of Self

Directory of Open Access Journals (Sweden)

Karin Willemse

2012-11-01

Full Text Available In this article, the focus is on how to represent narratives of self well. This dilemma concerns the specific narrative of self of Hajja, a market woman who lived in the provincial town of Kebkabiya, North Darfur, Sudan. The challenge of "responsible representation" in relation to her narrative concerns the question of how to represent a narrative that does not follow the expected structure of such a narrative. By considering the narrative as a performance of identities in the discursive and material context of narration, the author points out that a narrative is part and parcel of its context of narration. A representation of that narrative should therefore include elements of this context. Not only the discursive and verbal, but also the visual, spatial, and ultimately the temporal dimensions of the context allow us to understand narratives as enactments of self in a specific context. This consideration ties into the current debate on the nature of narrative. Narratives should not only be understood in terms of the what and how, but also in relation to the where and when of their narration. Narratives constitute spaces that allow the narrator a temporal moment of closure, of constructing oneself as a unified, coherent, bounded self in a specific place at a specific time.

Forensic analysis of questioned documents sometimes can be extensively data intensive. A forensic expert might need to analyze a heap of document fragments and in such cases to ensure reliability he/she should focus only on relevant evidences hidden in those document fragments. Relevant document retrieval needs finding of similar document fragments. One notion of obtaining such similar documents could be by using document fragment's physical characteristics like color, texture, etc. In this article we propose an automatic scheme to retrieve similar document fragments based on visual appearance of document paper and texture. Multispectral color characteristics using biologically inspired color differentiation techniques are implemented here. This is done by projecting document color characteristics to Lab color space. Gabor filter-based texture analysis is used to identify document texture. It is desired that document fragments from same source will have similar color and texture. For clustering similar document fragments of our test dataset we use a Self Organizing Map (SOM) of dimension 5×5, where the document color and texture information are used as features. We obtained an encouraging accuracy of 97.17% from 1063 test images.

Peak Oil and the Everyday Complexity of Human Progress Narratives

Directory of Open Access Journals (Sweden)

John C. Pruit

2012-11-01

Full Text Available The “big” story of human progress has polarizing tendencies featuring the binary options of progress or decline. I consider human progress narratives in the context of everyday life. Analysis of the “little” stories from two narrative environments focusing on peak oil offers a more complex picture of the meaning and contours of the narrative. I consider the impact of differential blog site commitments to peak oil perspectives and identify five narrative types culled from two narrative dimensions. I argue that the lived experience complicates human progress narratives, which is no longer an either/or proposition.

Narrating Identity: the Employment of Mythological and Literary Narratives in Identity Formation Among the Hijras of India

Directory of Open Access Journals (Sweden)

Jennifer Ung Loh

2014-06-01

Full Text Available This article explores how the hijras and kinnars of India use mythological narratives in identity-formation. In contemporary India, the hijras are a minority group who are ostracised from mainstream society as a result of their non-heteronormative gender performances and anatomical presentations. Hijras suffer discrimination and marginalisation in their daily lives, forming their own social groups outside of natal families and kinship structures. Mythological and literary narratives play a significant role in explaining and legitimising behavioural patterns, ritual practices, and anatomical forms that are specific to hijras, and alleviating some of the stigma surrounding this identity. In this article, I focus on certain narratives that hijras employ in making sense of and giving meaning to their lives, including mythological stories concerning people of ambiguous gender and myths associated with Bahuchara Mata. I argue that these ontological narratives serve to bring hijra identity into being and play a crucial role in constructing and authenticating hijra identity in modern India.

Mechanical properties and annealing texture of zirconium sheets

Hanif-ur-Rehman; Khawaja, F.A.

1996-01-01

Mechanical properties like yield strength (YS), ultimate tensile strength(UTS), percentage elongation and annealing texture has been studied in sheets of commercially pure zirconium. The YS and UTS decrease as a function of annealing temperature up to 600 V, but both quantities have maximum value in sample annealed at 800 deg. C. The percentage elongation decreased with increase in annealing temperature up to 600 deg. C. A slight decrease and minimum value of percentage elongation was observed at 650 and 800 C respectively. The texture development in the annealed samples has been studied by the X-ray diffraction method. The sampled annealed at 800 deg. C showed a texture component (0001) [01 bar 10] with orientation density of about 8 times random, while the samples annealed at 600,650 and 700 deg. C showed a texture component (0001)[2 bar 110] with orientation density of about 5 times random. Thus it is concluded, that the texture component (0001)[2 bar 110] and (0001)[01 bar 10] at 650 and 800 geg. C respectively, may be the responsible for the increase in YS and UTS and decrease in percentage elongation at these temperatures. (author)

Essa, Zahi; Taleb, Nadjib; Sermage, Bernard; Broussillou, Cédric; Bazer-Bachi, Barbara; Quillec, Maurice

2018-04-01

In crystalline silicon solar cells, the front surface is textured in order to lower the reflection of the incident light and increase the efficiency of the cell. This texturing whose dimensions are a few micrometers wide and high, often makes it difficult to determine the doping profile measurement. We have measured by secondary ion mass spectrometry (SIMS) and electrochemical capacitance voltage profiling the doping profile of implanted phosphorus in alkaline textured and in polished monocrystalline silicon wafers. The paper shows that SIMS gives accurate results provided the primary ion impact angle is small enough. Moreover, the comparison between these two techniques gives an estimation of the concentration of electrically inactive phosphorus atoms.

Narrative pedagogy and simulation: future directions for nursing education.

Science.gov (United States)

Walsh, Mike

2011-05-01

Narrative pedagogy has been developed over the last decade in nursing as a means of complementing a conventional content and competency driven pedagogy. It focuses attention on the human experience of health care by deriving shared meanings from interpretation of stories. This allows students to explore the different perspectives of those involved. The emotional experiences of participants can be understood, conventional wisdom challenged and new knowledge emerge as students work together to construct their learning. Individual stories are embedded within the narrative and teachers have successfully used literature and film as narratives to help them explore the meaning of health care with students. Modern technology has opened up a new range of electronic narratives such as virtual simulation. These are considered and rejected as devices for a health care narrative due to their dehumanized and unrealistic nature. However it is argued that a multimedia online simulation of a typical neighbourhood can achieve the goal of providing a suitable narrative. Human actors replace avatars and real world settings replace gaming environments as the stories of people in this community are related and used to support narrative pedagogy. An example of such a narrative developed jointly in the UK and Canada is discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

2013-12-01

Temporal information in clinical narratives plays an important role in patients' diagnosis, treatment and prognosis. In order to represent narrative information accurately, medical natural language processing (MLP) systems need to correctly identify and interpret temporal information. To promote research in this area, the Informatics for Integrating Biology and the Bedside (i2b2) project developed a temporally annotated corpus of clinical narratives. This corpus contains 310 de-identified discharge summaries, with annotations of clinical events, temporal expressions and temporal relations. This paper describes the process followed for the development of this corpus and discusses annotation guideline development, annotation methodology, and corpus quality. Copyright © 2013 Elsevier Inc.

"What Is Our Story?" Philip Morris's Changing Corporate Narrative.

McDaniel, Patricia A; Malone, Ruth E

2015-10-01

We sought to learn how employees reacted to changes in the corporate narrative of Philip Morris Companies (PMC) in the late 1990s and early 2000s. We analyzed archival internal tobacco industry documents about PMC's creation of a new corporate story. In response to litigation and public opprobrium, PMC replaced its market success-oriented corporate narrative with a new one centered on responsibility. Although management sought to downplay inconsistencies between the old and new narratives, some employees reportedly had difficulty reconciling them, concerned that the responsibility focus might affect company profitability. However, others embraced the new narrative, suggesting radical ideas to prevent youth smoking. These ideas were not adopted. PMC's new narrative was unconvincing to many of its employees, who perceived it either as a threat to the company's continued profits or as incongruous with what they had previously been told. As it had done with the public, PMC misled its employees in explaining a narrative repositioning that would help the company continue business as usual. Moving toward a tobacco endgame will require ongoing discursive and symbolic efforts to disrupt this narrative.

Volcanic lightning detection has become a useful resource for monitoring remote, under-instrumented volcanoes. Previous studies have shown that the behavior of volcanic plume electrification responds to changes in the eruptive processes and products. However, there has not yet been a study to quantify the links between ash textures and plume electrification during an actively monitored eruption. In this study, we examine a sequence of vulcanian eruptions from Sakurajima Volcano in Japan to compare ash textural properties (grain size, shape, componentry, and groundmass crystallinity) to plume electrification using a lightning mapping array and other monitoring data. We show that the presence of the continual radio frequency (CRF) signal is more likely to occur during eruptions that produce large seismic amplitudes (>7 μm) and glass-rich volcanic ash with more equant particle shapes. We show that CRF is generated during energetic, impulsive eruptions, where charge buildup is enhanced by secondary fragmentation (milling) as particles travel out of the conduit and into the gas-thrust region of the plume. We show that the CRF signal is influenced by a different electrification process than later volcanic lightning. By using volcanic CRF and lightning to better understand the eruptive event and its products these key observations will help the monitoring community better utilize volcanic electrification as a method for monitoring and understanding ongoing explosive eruptions.

Microstructure and mechanical characteristics of laser coating-texturing alloying dimples

2008-01-01

A novel laser coating-texturing (LCT) technique was proposed to achieve appropriate surface topographies and frictional behaviour. The LCT process was realized by applying laser pulses at very high repetition rate to produce innumerable micro-craters with required shape profile on the surface of the workpiece. Moreover, surface alloying of the dimples was carried out by melting submicron WC-TiC-Co alloy powder on the substrates. Morphology and microstructures of the texturing layers were characterised using optical microscopy (OM), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Mechanical properties of the textured samples were evaluated by abrasive resistance tests and microhardness measurement. Experimental results show that good fusion bonding between the texturing layers and the substrate has been formed, and the texturing layers are mainly composed of dense and hard fine-grained structures. The abrasive wear resistance of the laser coating-textured surface was 10 times higher than that of the substrates. The average surface microhardness values were as high as 830 HV.

Metabolic heterogeneity is a recognized characteristic of malignant tumors. Positron emission tomography (PET) texture analysis evaluated intratumoral heterogeneity in the uptake of (18)F-fluorodeoxyglucose. There were recent evidences that PET textural features were of prognostic significance in patients with different solid tumors. Unfortunately, there are still crucial standardization challenges to transform PET texture parameters from their current use as research tools into the arena of validated technologies for use in oncology practice. Testing its generalizability, robustness, consistency, and limitations is necessary before implementing it in daily patient care.

Effects of crystallographic texture on stress-migration resistance in copper thin films

International Nuclear Information System (INIS)

Koike, J.; Wada, M.; Sanada, M.; Maruyama, K.

2002-01-01

The crystallographic texture of heat-treated Cu thin films and its effects on stress-migration resistance were studied as a function of film thickness within a range of 50-900 nm. All as-deposited films had (111) texture. After heat treatment at 723 K, texture transition from (111) to (100) was observed in films of thickness greater than 300 nm. The (111) texture films after heat treatment showed severe stress migration; in contrast, the (100) texture films showed no noticeable stress migration. The observed stress-migration resistance in the (100) texture films can be attributed to the absence of twins and to lower thermal stress as compared with the (111) texture films

Summary Objectives We aimed to determine the characteristics of quantitative metrics for nursing narratives documented in electronic nursing records and their association with hospital admission traits and diagnoses in a large data set not limited to specific patient events or hypotheses. Methods We collected 135,406,873 electronic, structured coded nursing narratives from 231,494 hospital admissions of patients discharged between 2008 and 2012 at a tertiary teaching institution that routinely uses an electronic health records system. The standardized number of nursing narratives (i.e., the total number of nursing narratives divided by the length of the hospital stay) was suggested to integrate the frequency and quantity of nursing documentation. Results The standardized number of nursing narratives was higher for patients aged 70 years (median = 30.2 narratives/day, interquartile range [IQR] = 24.0–39.4 narratives/day), long (8 days) hospital stays (median = 34.6 narratives/day, IQR = 27.2–43.5 narratives/day), and hospital deaths (median = 59.1 narratives/day, IQR = 47.0–74.8 narratives/day). The standardized number of narratives was higher in “pregnancy, childbirth, and puerperium” (median = 46.5, IQR = 39.0–54.7) and “diseases of the circulatory system” admissions (median = 35.7, IQR = 29.0–43.4). Conclusions Diverse hospital admissions can be consistently described with nursing-document-derived metrics for similar hospital admissions and diagnoses. Some areas of hospital admissions may have consistently increasing volumes of nursing documentation across years. Usability of electronic nursing document metrics for evaluating healthcare requires multiple aspects of hospital admissions to be considered. PMID:27901174

NARRATIVE PERSPECTIVE MEDIATED BY MANNER OF MOTION VERBS

Directory of Open Access Journals (Sweden)

Olesea BODEAN-VOZIAN

2016-12-01

Full Text Available There is typological variation in the way languages encode manner as an element of a motion event. Languages like English view it as relevant, and the lexicalization of the variety of ways to move results in a rich class of motion verbs, contrary to other types of languages, like Romanian, which leave the manner element to be encoded by verbids or adverbs (for these reasons some linguists refer to the first type as manner-rich and second type as manner-poor languages. Still, several studies contrasting typologically different languages showed that languages of the latter type are not so poor in manner-of-motion verbs. The question then might rather be: which manner components are more likely to be lexicalized?For research purposes, we distinguish manner in terms of objective elements (medium, speed or intensity and subjective elements (attitude, intention. The aim of the study is to focus on the manner-of-motion verbs that embed an evaluative or qualitative dimension of motion and to examine the way these verbs encode somebody’s perspective in a narrative. The first question in such a case is whose evaluation or point of view is being represented. The second one is how the subjective point of view (narrative perspective mediated through manner-of-motion verbs in an English narrative (The Lord of the Rings, by J.R.R. Tolkien is translated into Romanian, supposedly a manner-poor or low-manner language.PERSPECTIVA NARATIVĂ MEDIATĂ DE VERBELE DE MIŞCARE DE MODExistă o variaţie tipologică în felul în care limbile codifică modul ca element al unui eveniment de mişcare.

Enabling narrative pedagogy: inviting, waiting, and letting be.

Science.gov (United States)

Ironside, Pamela M

2014-01-01

This article describes how teachers enable Narrative Pedagogy in their courses by explicating the Concernful Practice Inviting: Waiting and Letting Be. Narrative Pedagogy, a research-based, phenomenological approach to teaching and learning, extends conventional pedagogies and offers nursing faculty an alternative way of transforming their schools and courses. Using hermeneutic phenomenology, interview data collected over a 10-year period were analyzed by coding practical examples of teachers' efforts to enact Narrative Pedagogy. When Narrative Pedagogy is enacted, teachers and students focus on thinking and learning together about nursing phenomena and seek new understandings about how they may provide care in the myriad situations they encounter. Although the Concernful Practices co-occur, explicating inviting experiences can assist new teachers, and those seeking to extend their pedagogical literacy, by providing new understandings of how Narrative Pedagogy can be enacted.

Objetives This methodological study explain and emphasize the extent and fertility of the narrative interview in qualitative research. Methods To describe the narrative method within the qualitative research. Results The qualitative research method is characterized by addressing issues related to the singularities of the field and individuals investigated, being the narrative interviews a powerful method for use by researchers who aggregate it. They allow the deepening of research, the combination of life stories with socio-historical contexts, making the understanding of the senses that produce changes in the beliefs and values that motivate and justify the actions of possible informants. Conclusion The use of narrative is an advantageous investigative resource in qualitative research, in which the narrative is a traditional form of communication whose purpose is to serve content from which the subjective experiences can be transmitted.

Brown, Louis D; Berryhill, Joseph C; Jones, Eric C

2018-06-01

Media coverage of mental health and other social issues often relies on episodic narratives that suggest individualistic causes and solutions, while reinforcing negative stereotypes. Community narratives can provide empowering alternatives, serving as media advocacy tools used to shape the policy debate on a social issue. This article provides health promotion researchers and practitioners with guidance on how to develop and disseminate community narratives to broaden awareness of social issues and build support for particular programs and policy solutions. To exemplify the community narrative development process and highlight important considerations, this article examines a narrative from a mental health consumer-run organization. In the narrative, people with mental health problems help one another while operating a nonprofit organization, thereby countering stigmatizing media portrayals of people with mental illness as dangerous and incompetent. The community narrative frame supports the use of consumer-run organizations, which are not well-known and receive little funding despite evidence of effectiveness. The article concludes by reviewing challenges to disseminating community narratives, such as creating a product of interest to media outlets, and potential solutions, such as engaging media representatives through community health partnerships and using social media to draw attention to the narratives.

Narrative medicine allows professionals from all fields of medical sciences to understand the patient's total experience of illness, and meet his/her needs in an empathetic environment. Narrative medicine helps spread holistic knowledge of a multitude of complex clinical conditions, including transplantation. To underline the role of narrative medicine in women who become pregnant after a liver transplant by using their narrations of this very special experience. We describe our study with narration and listening to the stories of three women expecting their first child after a liver transplant, by analysing the structure and role of narration in the context of relationships between patients and caregivers. The narrations were transcribed verbatim with the main plot analysed in order to address all the aspects of this rare clinical condition and the transition to parenthood. The women narrated this experience in three phases: transplantation, pregnancy and delivery, and post-partum. They described all phases of pregnancy as stressful but satisfying, whereas the fact of becoming a mother was perceived as a victory both as a woman and as a transplant patient. Our results suggest that narrative medicine represents a significant professional tool for caring for transplant patients during pregnancy.

2015-01-01

The 17th International Conference on Textures of Materials (ICOTOM 17) took place in Dresden, Germany, August 24-29, 2014. It belongs to the 'triennial' series of ICOTOM meetings with a long tradition, starting in 1969 - Clausthal, 1971 - Cracow, 1973 - Pont-à-Mousson, 1975 - Cambridge, 1978 - Aachen, 1981 - Tokyo, 1984 - Noordwijkerhout, 1987 - Santa Fe, 1990 - Avignon, 1993 - Clausthal, 1996 - Xian, 1999 - Montreal, 2002 - Seoul, 2005 - Leuven, 2008 - Pittsburgh, 2011 - Mumbai, 2014 - Dresden. ICOTOM 17 was hosted by the Dresden University of Technology, Institute of Structural Physics. Following the tradition of the ICOTOM conferences, the main focus of ICOTOM-17 was to promote and strengthen the fundamental understanding of the basic processes that govern the formation of texture and its relation to the properties of polycrystalline materials. Nonetheless, it was the aim to forge links between basic research on model materials and applied research on engineering materials of technical importance. Thus, ICOTOM 17 provided a forum for the presentation and discussion of recent progress in research of texture and related anisotropy of mechanical and functional properties of all kinds of polycrystalline materials including natural materials like rocks. Particular attention was paid to recent advances in texture measurement and analysis as well as modeling of texture development for all kinds of processes like solidification, plastic deformation, recrystallization and grain growth, phase transformations, thin film deposition, etc. Hence, ICOTOM 17 was of great interest to materials scientists, engineers from many different areas and geoscientists. The topics covered by ICOTOM 17 were: 1. Mathematical, numerical and statistical methods of texture analysis 2. Deformation textures 3. Crystallization, recrystallization and growth textures 4. Transformation textures 5. Textures in functional materials 6. Textures in advanced materials 7. Textures in rocks 8
