  3. A historical discourse analysis of the cancerous and non-cancerous body in secondary biology textbooks

    NASA Astrophysics Data System (ADS)

    Bowers, Neil Thomas

    This dissertation applies the archeological concepts developed by Michel Foucault to a study of thirteen biology textbooks (1993-2004) in order to develop an understanding of 'purchased truths' concerning cancer. This study focuses on the construction of the health/illness dialogue concerning cancer within the textbooks and not the meaning that the individual makes from reading the text; as such this study concerns itself with social truths rather than the search for an individual awareness of names, dates, or places. This study investigates the practices that allow the creation of dialogues that are inserted into a biology textbook and looks at how discursive formations create the 'truth regime' from which the biology textbook is said to speak. Using the Foucaultian themes of 'event', 'emergence', 'enunciation', and 'exteriority' a new reading of topics concerning cancer emerge from biology textbooks. Cancer is a disease that will impact the lives of countless individuals but coverage devoted to the pathology of cancer in secondary biology textbooks is very limited and no study textbook devoted a whole chapter to the discussion of cancer. There is an identified reduction in the number of pages and depth of coverage devoted to cancer in the newer biology texts compared to the older texts. Humans are pictured more than plants or animals in presentations concerning cancer with emphasis being placed on the digitalization of human cells via the scanning electron microscope. When the whole body is presented it is seldom located within the technology of disease diagnosis and treatment but rather is posed for specific social control. Just as each digitized picture of the cancerous cell in the texts is used to create a story so too are the pictures of the whole body in action. Possible story lines offered by the publishing houses concerning the reaction of the body to cancer are shown to intermingle with risk factor analysis to project a sense of Foucaultian 'governmentality' based on assumed control and self regulation by the informed reader. In conclusion a procedure is suggested to further analyze additional textbooks concerning biological/educational issues that have been recast as social problems.

  4. Psychotherapeutic discourse analysis.

    PubMed

    Lewis, B

    1995-01-01

    Psychotherapeutic discourse analysis is a significant, largely unexplored, tool for psychotherapist and an ideal data sight for linguists. Increased multidisciplinary research in this area would be particularly fruitful. Conversations, including therapeutic conversations, are far from transparent conduits of information from one person to another. Complicating surface communication is "metacommunication," which takes the form of unconscious conversational styles--culturally influenced rules, norms, and expectations of how a conversation should proceed. If the therapist and the patient are working with different conversational styles, then blocks in communication and understanding are inevitable. Through discourse analysis conversational styles can become more available to awareness for use in the service of therapeutic goals. This paper is an example of a discourse analysis of an individual therapy session. I attempt to bridge the gap between broad psychodynamic treatment strategies and minute micro-conversational strategies that can be used to enhance the therapeutic process. PMID:8546235

  6. Changing social and scientific discourses on type 2 diabetes between 1800 and 1950: a socio-historical analysis.

    PubMed

    O'Donnell, Shane

    2015-09-01

    Since the emergence of type 2 diabetes as a public health threat around the middle of the 20(th) century, accounts of disease causation have focused predominately on lifestyle or genetics, or both, while the role of broader structural issues such as psychosocial distress has been downplayed. Yet in the years prior to this emergence, when diabetes remained the preserve of the upper classes, medical experts drew upon multiple narratives when considering the condition, the most popular of which being the role of social organisation and the interplay between mind, body and environment. This article is based on a discourse analysis of the writings of the most prominent diabetes experts between 1800 and 1950 about both the causes and management of the illness. It highlights how, although the connection between lifestyle and diabetes was well established among physicians, individual-level explanations only fully supplanted the emphasis on social organisation as diabetes began to make the transition from being a disease of the rich to one of the poor. It argues that this discursive shift was shaped by the dynamics of class relations rather than any new forms of scientific evidence developed at the time. PMID:26094811

    Connors, Robert J.

    Although first enunciated in 1827 by Samuel Newman, the modes of discourse--narration, description, exposition, and argument--were not very popular until formulated in 1866 and presented in the United States in a rhetoric textbook in 1885. After 1890, they were gradually accepted by the most influential rhetoricians of the day, and their use in…

  9. Perezhivanie and classroom discourse: a cultural-historical perspective on "Discourse of design based science classroom activities"

    NASA Astrophysics Data System (ADS)

    Adams, Megan; March, Sue

    2015-06-01

    Flavio Azevedo, Peggy Martalock and Tugba Keser challenge the `argumentation focus of science lessons' and propose that through a `design-based approach' emergent conversations with the teacher offer possibilities for different types of discussions to enhance pedagogical discourse in science classrooms. This important paper offers a "preliminary contribution to a general theory" regarding the link between activity types and discourse practices. Azevedo, Martalock and Keser offer a general perspective with a sociocultural framing for analysis of classroom discourse. Interestingly the specific concepts drawn upon are from conversation analysis; there are few sociocultural concepts explored in detail. Therefore, in this article we focus on a cultural historical (Vygotsky in The collected works of L. S. Vygotsky. The history and development of higher mental functions, vol 4. Plenum Press, New York, 1987; The Vygotsky reader. Black, Cambridge, 1994) methodology to explore, analyse and explain how we would use a different theoretical lens. We argue that a cultural historical reading of argumentation in science lessons and design based activity will expand Azevedo, Martalock and Keser's proposed general theory of activity types and discourse practices. Specifically, we use Lev Vygotksy's idea of perezhivanie as the unit of analysis to reconceptualise this important paper. We focus on the holistic category of students' emotional experience through discourse while developing scientific awareness.

  17. Discourse analysis and social constructionism.

    PubMed

    White, Robert

    2004-01-01

    Discourse analysis (DA) is underpinned by a social constructionist orientation to knowledge. Social constructionism rests on the philosophical assumptions that multiple versions of the world are legitimate; that texts are open to multiple readings; and that language is non-representational. As social constructionism is relativistic, the status of 'evidence' generated by DA is questionable from more traditional research perspectives. On a common-sense level, people obviously construct meaning in relation to their lives. Thus, DA can help us to examine constructions of meaning in relation to nursing care. Equally the discourse analyst constructs one possible meaning in relation to a phenomenon that may compete with other versions. Multiplicity does not necessarily entail anarchy and competing versions prevent authoritarianism and loss of freedom. However, judgements have to be made about competing versions, for example, by assessing the level of 'facticity', or referring to the ethics embedded in the cultural context. In this paper, Bob White discusses DA as a form of qualitative research that offers promise for nursing research. Subsequent papers will examine the methodology and methods of DA and its application to nursing research. PMID:15636002

  18. A cultural historical theoretical perspective of discourse and design in the science classroom

    NASA Astrophysics Data System (ADS)

    Adams, Megan

    2015-06-01

    Flavio Azevedo, Peggy Martalock and Tugba Keser have initiated an important conversation in science education as they use sociocultural theory to introduce design based scenarios into the science classroom. This response seeks to expand Azevedo, Martalock and Keser's article The discourse of design- based science classroom activities by using a specific perspective within a sociocultural framework. Through using a cultural historical (Vygotsky in The history and development of higher mental functions, Plenum Press, New York, 1987) reading of design based activity and discourse in the science classroom, it is proposed that learning should be an integral part of these processes. Therefore, everyday and scientific concepts are explained and expanded in relation to Inventing Graphing and discourse presented in Azevedo, Martalock and Keser's article. This response reports on the importance of teacher's being explicit in relation to connecting everyday and scientific concepts alongside design based activity and related science concepts when teaching students. It is argued that explicit teaching of concepts should be instigated prior to analysis of discourse in the science classroom as it is only with experience and understanding these processes that students have the resources to call upon to argue like practicing scientists.

    2014-12-01

    Research studies using discourse analysis approaches make claims about phenomena or issues based on interpretation of written or spoken text, which includes images and gestures. How are findings/interpretations from discourse analysis validated? This paper proposes transdisciplinary convergence as a way to validate discourse analysis approaches to research. The argument is made that discourse analysis explicitly grounded in semiotics, systemic functional linguistics, and critical theory, offers a credible research methodology. The underlying assumptions, constructs, and techniques of analysis of these three theoretical disciplines can be drawn on to show convergence of data at multiple levels, validating interpretations from text analysis.

  8. Discourses of Linguistic dominance: A Historical Consideration of French Language Ideology

    NASA Astrophysics Data System (ADS)

    Kasuya, Keisuke

    2001-07-01

    The paper offers a historical perspective on the linguistic and cultural imperialism embedded in the struggle to maintain French as a leading international language. France was the nation-state where the ideology of national language was first clearly formulated and directly extended to overseas colonies. This shows the close relationship between linguistic nationalism and imperialism. It was believed that French was the language of universal human reason and had the power to civilize people who spoke it. This myth of the "clarté française" and the "mission civilisatrice" had a strong influence on various kinds of metalinguistic discourses that created the taken-for-granted representation of French as dominant language. It is the essential strategy of language dominance to establish the hierarchy of languages as if it were natural order of things. When French was obliged to yield the status of international language to English, there emerged the ideology of "Francophonie" which tried to defend its privilege against the monopoly of English, but the same ideology is also directed against minorities' claims for their own linguistic human right. It could be said that these discourses form a recursive prototype of language dominance whose variations are to be found in other shapes almost all over the world.

  9. Facilitating Discourse Analysis with Interactive Visualization.

    PubMed

    Zhao, Jian; Chevalier, F; Collins, C; Balakrishnan, R

    2012-12-01

    A discourse parser is a natural language processing system which can represent the organization of a document based on a rhetorical structure tree-one of the key data structures enabling applications such as text summarization, question answering and dialogue generation. Computational linguistics researchers currently rely on manually exploring and comparing the discourse structures to get intuitions for improving parsing algorithms. In this paper, we present DAViewer, an interactive visualization system for assisting computational linguistics researchers to explore, compare, evaluate and annotate the results of discourse parsers. An iterative user-centered design process with domain experts was conducted in the development of DAViewer. We report the results of an informal formative study of the system to better understand how the proposed visualization and interaction techniques are used in the real research environment.

  10. Doing Foucault: inquiring into nursing knowledge with Foucauldian discourse analysis.

    PubMed

    Springer, Rusla Anne; Clinton, Michael E

    2015-04-01

    Foucauldian discourse analysis (FDA) is a methodology that is well suited to inquiring into nursing knowledge and its organization. It is a critical analytic approach derived from Foucault's histories of science, madness, medicine, incarceration and sexuality, all of which serve to exteriorize or make visible the 'positive unconscious of knowledge' penetrating bodies and minds. Foucauldian discourse analysis (FDA) holds the potential to reveal who we are today as nurses and as a profession of nursing by facilitating our ability to identify and trace the effects of the discourses that determine the conditions of possibility for nursing practice that are continuously shaping and (re)shaping the knowledge of nursing and the profession of nursing as we know it. In making visible the chain of knowledge that orders the spaces nurses occupy, no less than their subjectivities, FDA is a powerful methodology for inquiring into nursing knowledge based on its provocation of deep critical reflection on the normalizing power of discourse.

  11. Power in clinical teachers' discourses of a curriculum-in-action. Critical discourse analysis.

    PubMed

    Graham, Jennifer; Dornan, Tim

    2013-12-01

    "Curricula-in-action" generally differ from "official" curricula. That is particularly true of clerkship curricula because the practising doctors who supervise medical students' clinical activities are only secondarily educators. Clerkship education is evaluated, however, according to benchmarks set by official curricula. As a result, clerkship evaluations are important points of contact between clinical teachers and medical schools. We reasoned that an evaluation instrument is part of a medical school's official curriculum discourse and clinical teachers' reactions to it are a discourse of curriculum-in-action. We set out to answer the questions: What are clinical teachers' discourses of curriculum-in-action and how do they relate to an official curriculum discourse? Nineteen clerkship placement leads from two hospitals contributing to a single undergraduate medical programme participated. The evaluation instrument was the Manchester Clinical Placement Index, for which validity evidence has been published. Respondents were asked to say how they would react to junior students giving their placements low or high scores for each of 12 items from the Index. After transcription, we conducted a critical discourse analysis (CDA) of their audio-recorded answers. We purposefully selected the six items that elicited the widest spectrum of responses for analysis because quantity of material can compromise the quality of CDA. A dominant discourse of curriculum-in-action defined how teachers should "really" teach and junior students should learn. It deconstructed the need for teachers to be present when students performed clinical tasks because teachers' role was to give critical feedback on case presentations that were coincidental to clinical care. It positioned students at the bottom of a power hierarchy so they had to "struggle" to be taught. It placed respondents in a powerful position relative to "the hospital" and "the university", though there were tensions between respondents, patients, and nurses. Respondents dismissed criticism that was invalid according to their curriculum-in-action, which included most items in an evaluation instrument. There was a contrasting, non-dominant discourse of responding reflectively to feedback, which generated realistic ways of improving students' learning. The strength of respondents' emotions shows just how committed doctors are to students' learning. The strength of their expressions of power, however, explains why many of them teach in their own way rather than according to official curricula. Changes to clinical curricula, our findings suggest, will not be successful unless they are carefully negotiated with practising doctors. PMID:23283572

  13. Uniting postcolonial, discourse, and linguistic theory to explore participation of African Americans in cancer research as an effect of social and historical race relationships.

    PubMed

    Somayaji, Darryl; Cloyes, Kristin Gates

    2014-01-01

    This article uses a historical framework of postcolonialism; discourse analytic concepts (significance, identity, and relationships); and 5 social and cultural linguistic principles of emergence, positionality, indexicality, relationality, and partialness as a theoretical and methodological triangulation approach to data analysis of focus group discussion. Exemplars of focus group data from a study exploring African American participation in research demonstrate the application of this combined framework as a useful tool for analysis. This approach allows for examination of identity and interaction and generates a more rigorous and complete understanding of how individuals use language to construct identity as participants or nonparticipants in research.

  16. The organising vision for telehealth and telecare: discourse analysis

    PubMed Central

    Procter, Rob; Wherton, Joe; Sugarhood, Paul; Shaw, Sara

    2012-01-01

    Objective To (1) map how different stakeholders understand telehealth and telecare technologies and (2) explore the implications for development and implementation of telehealth and telecare services. Design Discourse analysis. Sample 68 publications representing diverse perspectives (academic, policy, service, commercial and lay) on telehealth and telecare plus field notes from 10 knowledge-sharing events. Method Following a familiarisation phase (browsing and informal interviews), we studied a systematic sample of texts in detail. Through repeated close reading, we identified assumptions, metaphors, storylines, scenarios, practices and rhetorical positions. We added successive findings to an emerging picture of the whole. Main findings Telehealth and telecare technologies featured prominently in texts on chronic illness and ageing. There was no coherent organising vision. Rather, four conflicting discourses were evident and engaged only minimally with one another's arguments. Modernist discourse presented a futuristic utopian vision in which assistive technologies, implemented at scale, would enable society to meet its moral obligations to older people by creating a safe ‘smart’ home environment where help was always at hand, while generating efficiency savings. Humanist discourse emphasised the uniqueness and moral worth of the individual and tailoring to personal and family context; it considered that technologies were only sometimes fit for purpose and could create as well as solve problems. Political economy discourse envisaged a techno-economic complex of powerful vested interests driving commodification of healthcare and diversion of public funds into private business. Change management discourse recognised the complicatedness of large-scale technology programmes and emphasised good project management and organisational processes. Conclusion Introduction of telehealth and telecare is hampered because different stakeholders hold different assumptions, values and world views, ‘talk past’ each other and compete for recognition and resources. If investments in these technologies are to bear fruit, more effective inter-stakeholder dialogue must occur to establish an organising vision that better accommodates competing discourses.

  13. Discourse analysis and the impact of the philosophy of Enlightenment in nursing research.

    PubMed

    Beedholm, Kirsten; Lomborg, Kirsten; Frederiksen, Kirsten

    2014-06-01

    Discourse analysis has been introduced into nursing research as an approach which has the potential to offer new perspectives and to pose new questions to taken-for-granted assumptions. However, critique has arisen that when applied to nursing studies, the epistemological foundation of the discourse analysis is often overlooked. It is furthermore claimed that the methodological inspiration does not lead to any new insights and that these studies can hardly be differentiated from more traditional studies. This study supports this critique, arguing that the challenges of implementing discourse analysis in nursing research reflect a dominant pattern of thought in the discourse of the nursing profession that have held sway throughout the last century. We argue that this pattern of thought stems from the Western philosophy of consciousness and the conception of the sovereign subject. By applying a discourse analytical perspective to the discourse of the nursing profession itself, this study elucidates the challenges of applying discourse analysis in nursing research.

  19. A discourse analysis of male sexuality in the magazine Intimacy

    PubMed Central

    2015-01-01

    Abstract Background The World Health Organization's publication, Developing sexual health programmes, states that the media is an important source of information about sexuality. Although the media can promote awareness of sexual health issues, it also acts as a vehicle for defining and regulating sex norms. In other words, the standards of ‘normal’ sex are in part defined by the media. Accordingly, it has become imperative to analyse the media's construction of sexual norms in order to reveal how they are related to specific ideological views. For the purposes of this study, the focus will be limited to analysing the South African publication Intimacy. Aim The study aims to reveal how the sex advice articles written in Intimacy for women in regard to their male partner's sexuality reflect patriarchal and phallocentric ideologies. Method A discourse analysis of the sex advice articles in the magazine Intimacy was conducted. It was informed by feminist theories of sexuality that seek to examine the ways in which texts are associated with male-centred versions of sexual pleasure. Results The discourse analysis identified a number of key themes regarding male sexuality. These include: (1) biological accounts of male sexuality; (2) phallocentric scripting of the sex act; and (3) the melodramatic penis. Conclusion Constructions of male sexuality require the inclusion of alternative modes of male erotic pleasure. This requires texts that encourage men to explore and also to experiment with pleasurable feelings associated with non-genital erogenous zones of the body. PMID:26245621

  12. Highlighting hybridity: A critical discourse analysis of teacher talk in science classrooms

    NASA Astrophysics Data System (ADS)

    Hanrahan, Mary U.

    2006-01-01

    There is evidence that alienation from science is linked to the dominant discourse practices of science classrooms (cf. Lemke, J. L. (1990). Talking Science: Language, Learning, and Values. Norwood, NJ: Ablex). Yet, in secondary science education it is particularly hard to find evidence of curriculum reform that includes explicit changes in pedagogic discourses to accommodate the needs of students from a wide range of backgrounds. However, such evidence does exist and needs to be highlighted wherever it is found to help address social justice concerns in science education. In this article, I show how critical discourse analysis can be used to explore a way of challenging the dominant discourse in teacher - student interactions in science classrooms. My findings suggest a new way of moving toward more socially just science curricula in middle years and secondary classrooms by using hybrid discourses that can serve emancipatory purposes.

  14. Comparative Critical Discourse Analysis (CDA): Interplay of discourses (D/D1) as third grade urban and suburban science students engage in hypothesis formulation and observation

    NASA Astrophysics Data System (ADS)

    Mendoza, Carmen Irene Reyes

    This qualitative research project is a comparative analysis of Discourses (D/D1) while focused upon the science processes of hypothesis generation and observation in an urban versus suburban elementary science classroom. D designates the instructional and formal academic science Discourse and D1 represents the students' informal, social or home language D1iscourses. In particular, this research study is a critical discourse analysis that examines how the science processes of hypothesis formulation and observation are constituted through the interplay of classroom Discourses (D/D1) as two third grade science teachers teach the same kit-based, inquiry science lessons with their respective urban and suburban students. The research also considers ethnicity, social class, language, and the central role science teachers play mediating between children's everyday world and the world of science. Communicative approach and distinctive patterns of interaction between the European American teachers and their respective students are analyzed through a critical lens to examine underlying issues of equity and power embedded in the instructional Discourse of science. Critical Discourse Analysis (CDA) provides both the theoretical framework and analytical lens. The research informs development of linguistic-based "best" practices to contribute toward promoting greater science teacher awareness in creating linguistic environments that support all students' learning science Discourse and to serve as a springboard for future educational science researchers' use of CDA.

  15. The Chronic Responsibility: A Critical Discourse Analysis of Danish Chronic Care Policies.

    PubMed

    Ravn, Iben M; Frederiksen, Kirsten; Beedholm, Kirsten

    2016-03-01

    This article reports on the results of a Fairclough-inspired critical discourse analysis aiming to clarify how chronically ill patients are presented in contemporary Danish chronic care policies. Drawing on Fairclough's three-dimensional framework for analyzing discourse, and using Dean's concepts of governmentality as an interpretative lens, we analyzed and explained six policies published by the Danish Health and Medicines Authority between 2005 and 2013. The analysis revealed that discourses within the policy vision of chronic care consider chronically ill patients' active role, lifestyle, and health behavior to be the main factors influencing susceptibility to chronic diseases. We argue that this discursive construction naturalizes a division between people who can actively manage responsible self-care and those who cannot. Such discourses may serve the interests of those patients who are already activated, while others remain subjugated to certain roles. For example, they may be labeled as "vulnerable." PMID:25662943

  16. Exploring the discourse on communication modality after cochlear implantation: a Foucauldian analysis of parents' narratives.

    PubMed

    Bruin, Marieke; Nevøy, Anne

    2014-07-01

    After pediatric cochlear implantation, parents have to make decisions concerning which communication modality the child and the child's family will use. The choice has to be made against a background of opposing views on communication modality in follow-up after pediatric cochlear implantation. The opposing views form a discourse that has been a core issue in the international body of literature for a long time. For hearing parents caught up in this ongoing controversy, the choice can be a difficult one. The study reported in this article explores the discourse on communication modality and is based on 27 written parental accounts on experiences with follow-up. From the perspective of Foucault's thinking, discourses exert knowledge and power. Drawing on Foucault, the study explores how the discourse on communication modality is constructed, how it operates, and how it governs thinking and acting. The Foucauldian analysis brings to the fore the complex nature of the discourse and states that follow-up, which is intended to be helpful for parents, may induce insecurity and frustration. The study brings into conversation a broader understanding of the discourse on communication modality and addresses a need for increased awareness on how the discourse governs thinking and acting in follow-up.

  8. A Historical Analysis of the Relationship of Faith and Science and its Significance within Education

    NASA Astrophysics Data System (ADS)

    Yegge, John G.

    Science curriculum and pedagogy are at the center of a centuries-long debate concerning the appropriate relationship of faith and science. The difficulties that science educators face seem to be based in misinformation about the historical roots of this conflict. To address that conflict, the goals of this research were to separate myth from reality and to provide a necessary context to the current tensions that are disrupting science pedagogy and curriculum content within American public schools. Working within a theoretical framework of historical literacy, this qualitative, historical analysis was a comprehensive examination of the relationship of faith and science from ancient times through the Renascence to the emergence and development of Darwinism. The historical approach methodology was utilized as a means to document the systematic examination of past events, in order to illuminate and interpret the meaning of those events. The historical record revealed that science and religion are not necessarily incompatible and that the early Christian religion provided a fertile environment in which modern science could emerge. Also noted were many instances where the record was inconsistent with what educators have commonly taught as historical fact. Finally, the complex sources of tension between modern fundamentalist Christianity and Darwinism, which has appeared as a flashpoint in public discourse within science education, were examined in depth. Based on this analysis, the study includes recommendations for educators in their approach to addressing these challenges and teaching science. This analysis can produce positive social change for educators and their students, as this information is advanced as a means to enhance historical literacy among educators and their students.

    PubMed

    Dixon, Kathleen A

    2013-08-01

    The aim of this study was to uncover and critically examine hidden assumptions that underpin the findings of nurses' unethical conduct arising from inquiries conducted by the Nurses Tribunal in New South Wales. This was a qualitative study located within a post-structural theoretical framework. Transcripts of five inquiries conducted between 1998 and 2003 were analysed using critical discourse analysis. The findings revealed two dominant discourses that were drawn upon in the inquiries to construct nurses' conduct as unethical. These were discourses of trust and accountability. The way the nurses were spoken about during the inquiries was shaped by normalising judgements that were used to discursively position the nurse through narrative. PMID:23378542

  10. Othering the Chronically Ill: A Discourse Analysis of New Zealand Health Policy Documents.

    PubMed

    Walton, Jo Ann; Lazzaro-Salazar, Mariana

    2016-04-01

    It is widely recognized that chronic illnesses pose significant challenges for health care systems around the world. In response, most governments have set health policies in order to manage (or better, reduce) demand and improve the health of their populations. A discourse analysis of four policy documents that shape these strategies in New Zealand reveals that the policies construct the chronically ill as "others," that is, as deviant or different from the "normal" population. The discourse further serves to blame the chronically ill both for being sick, and for placing a serious financial burden on society. We identify problems that arise from this discourse. They relate to (a) the fact that chronic illnesses are so prevalent, (b) the fallacy of categorizing all chronic illnesses as the same, PMID:26422127

  13. Discourses of aggression in forensic mental health: a critical discourse analysis of mental health nursing staff records.

    PubMed

    Berring, Lene L; Pedersen, Liselotte; Buus, Niels

    2015-12-01

    Managing aggression in mental health hospitals is an important and challenging task for clinical nursing staff. A majority of studies focus on the perspective of clinicians, and research mainly depicts aggression by referring to patient-related factors. This qualitative study investigates how aggression is communicated in forensic mental health nursing records. The aim of the study was to gain insight into the discursive practices used by forensic mental health nursing staff when they record observed aggressive incidents. Textual accounts were extracted from the Staff Observation Aggression Scale-Revised (SOAS-R), and Fairclough's critical discourse analysis was used to identify short narrative entries depicting patients and staffs in typical ways. The narratives contained descriptions of complex interactions between patient and staff that were linked to specific circumstances surrounding the patient. These antecedents, combined with the aggression incident itself, created stereotyping representations of forensic psychiatric patients as deviant, unpredictable and dangerous. Patient and staff identities were continually (re)produced by an automatic response from the staff that was solely focused on the patient's behavior. Such response might impede implementation of new strategies for managing aggression. PMID:26138668

    An investigation is conducted regarding the value of existing aerial photographs for waste management, including landfill monitoring. The value of historic aerial photographs for documenting landfill boundaries is shown in a graph in which the expansion of an active landfill is traced over a 40-year period. Historic aerial photographs can also be analyzed to obtain general or detailed land-use and land-cover information. In addition, the photographs provide information regarding other elements of the physical environment, including geology, soils, and surface and subsurface drainage. The value of historic photos is discussed, taking into account applications for inventory, assessing contamination/health hazards, planning corrective measures, planning waste collection and facilities, developing inactive landfills, and research concerning improved land-filling operations.

  3. Uncertainty Analysis of Historical Hurricane Data

    Green, Lawrence L.

    2007-01-01

    An analysis of variance (ANOVA) study was conducted for historical hurricane data dating back to 1851 that was obtained from the U. S. Department of Commerce National Oceanic and Atmospheric Administration (NOAA). The data set was chosen because it is a large, publicly available collection of information, exhibiting great variability which has made the forecasting of future states, from current and previous states, difficult. The availability of substantial, high-fidelity validation data, however, made for an excellent uncertainty assessment study. Several factors (independent variables) were identified from the data set, which could potentially influence the track and intensity of the storms. The values of these factors, along with the values of responses of interest (dependent variables) were extracted from the data base, and provided to a commercial software package for processing via the ANOVA technique. The primary goal of the study was to document the ANOVA modeling uncertainty and predictive errors in making predictions about hurricane location and intensity 24 to 120 hours beyond known conditions, as reported by the data set. A secondary goal was to expose the ANOVA technique to a broader community within NASA. The independent factors considered to have an influence on the hurricane track included the current and starting longitudes and latitudes (measured in degrees), and current and starting maximum sustained wind speeds (measured in knots), and the storm starting date, its current duration from its first appearance, and the current year fraction of each reading, all measured in years. The year fraction and starting date were included in order to attempt to account for long duration cyclic behaviors, such as seasonal weather patterns, and years in which the sea or atmosphere were unusually warm or cold. The effect of short duration weather patterns and ocean conditions could not be examined with the current data set. The responses analyzed were the storm latitude, longitude and intensity, as recorded in the data set, 24 or 120 hours beyond the current state. Several ANOVA modeling schemes were examined. Two forms of validation were used: 1) comparison with official hurricane prediction performance metrics and 2) cases studies conducted on hurricanes from the 2005 season, which were not included within the model construction and ANOVA assessment. In general, the ANOVA technique did not perform as well as the established official prediction performance metrics published by NOAA; still, the technique did remarkably well in this demonstration with a difficult data set and could probably be made to perform better with more knowledge of hurricane development and dynamics applied to the problem. The technique provides a repeatable prediction process that eliminates the need for judgment in the forecast.

    2007-09-01

    By using the historical data from the Japanese banks’ database at “The Bankers Library” of Japanese Banker Association, we analyze the historical network of banks from 1868 to 2006. Firstly, we define a bank every year by a particle and draw a space-time evolution process of merger, division, establishment, and failure by a tree diagram structure. We found that the distribution of the tree basin size of real data and simulation result are mostly fitting well. Secondly, we analyze the raw data of financial statements of banks collected by the National Diet library. We confirm that the distributions of the amount of deposits have fat-tail every year, however, small deviations are observed relating to governmental policy.

  7. An Analysis of Argumentation Discourse Patterns in Elementary Teachers' Science Classroom Discussions

    NASA Astrophysics Data System (ADS)

    Kim, Sungho; Hand, Brian

    2015-04-01

    This multiple case study investigated how six elementary teachers' argumentation discourse patterns related to students' discussions in the science classroom. Four categories of classroom characteristics emerged through the analysis of the teachers' transcripts and recorded class periods: Structure of teacher and student argumentation, directionality, movement, and structure of student talk. Results showed that the differences between the teachers' discourse patterns were related to their modified reformed teaching observation protocol (RTOP) scores and to how the interaction of those differences affected student learning. Teachers with high RTOP scores were more likely to challenge their students' claims, explanations, and defenses and to provide less guidance and more waiting time for their students' responses than teachers with medium- and low-level RTOP scores. Students in the high-level teachers' classes challenged, defended, rejected, and supported each other's ideas with evidence and required less guidance than students in the medium-level and low-level teachers' classes.

  8. Retrospective Analysis of Communication Events - Understanding the Dynamics of Collaborative Multi-Party Discourse

    2006-06-08

    This research is aimed at understanding the dynamics of collaborative multi-party discourse across multiple communication modalities. Before we can truly make sig-nificant strides in devising collaborative communication systems, there is a need to understand how typical users utilize com-putationally supported communications mechanisms such as email, instant mes-saging, video conferencing, chat rooms, etc., both singularly and in conjunction with traditional means of communication such as face-to-face meetings, telephone calls and postal mail. Attempting to un-derstand an individual’s communications profile with access to only a single modal-ity is challenging at best and often futile. Here, we discuss the development of RACE – Retrospective Analysis of Com-munications Events – a test-bed prototype to investigate issues relating to multi-modal multi-party discourse.

  9. Exploring the communication between telenurse and caller—A critical discourse analysis

    2014-01-01

    Background Telenursing is an expanding service in most Western societies. Sweden is a front-line country, with all of its 21 counties connected to Swedish Healthcare Direct (SHD) 1177. The intention of the service is twofold: to make health care more efficient, while also making it more accessible and safe for patients. Previous research has shown, however, that the service is not used equitably. Gender, age, socio-economic, and ethnicity differences have been reported as determining factors for the use of the service and the advice given. Aim The aim of the study was to explore the communication between telenurses and callers in authentic calls to SHD 1177. Methodology A qualitative method, using critical discourse analysis (CDA), was chosen. The approach was deductive, that is, the analysis was made in view of a predetermined framework of theory. Twenty calls were strategically chosen and included in the study. Results The CDA resulted in five types of calls, namely a gatekeeping call, a gendered call, a call marked by impersonal traits, a call with voices of the life world, and finally a counter discourse call. The dominating patterns in the calls were of gatekeeping and biomedical character. Patterns of the societal gender order were found, in that representations of the reluctant male caller and the ideal female caller were identified, but also a call representing a counter discourse. The service seemed difficult to use for patients with low language proficiency. Conclusion Telenursing could potentially challenge inequalities in health care. However, the discourse of telenursing is dialectically related to neoliberal ideology and the ideology of medicine. It is also situated in a gendered context of ideal femininity and hegemonic masculinity. Through better awareness of gender biases and the callers’ different resources for making themselves heard, the communication between telenurse and caller might become more equal and thereby better suitable for all callers.

    A descriptive review is presented of the most recent methods for performing sensitivity analysis of the structural behavior of discretely-modeled systems. The methods are generally but not exclusively aimed at finite element modeled structures. Topics included are: selections of finite difference step sizes; special consideration for finite difference sensitivity of iteratively-solved response problems; first and second derivatives of static structural response; sensitivity of stresses; nonlinear static response sensitivity; eigenvalue and eigenvector sensitivities for both distinct and repeated eigenvalues; and sensitivity of transient response for both linear and nonlinear structural response.

  12. Tell me what's wrong with me: a discourse analysis approach to the concept of patient autonomy.

    Nessa, J; Malterud, K

    1998-01-01

    BACKGROUND: Patient autonomy has gradually replaced physician paternalism as an ethical ideal. However, in a medical context, the principle of individual autonomy has different meanings. More knowledge is needed about what is and should be an appropriate understanding of the concept of patient autonomy in clinical practice. AIM: To challenge the traditional concept of patient autonomy by applying a discourse analysis to the issue. METHOD: A qualitative case study approach with material from one consultation. The discourse is interpreted according to pragmatic and text-linguistic principles and provides the basis of a theoretical discussion of different concepts of patient autonomy. RESULTS: The consultation transcript illustrates how the patient's wishes can be respected in real life. The patient, her husband and the doctor are all involved in the discourse dynamics, governed by the subject matter, namely her mental illness. CONCLUSION: We suggest a dynamic and dialogue-based conception of autonomy as adequate for clinical purposes. These perspectives, based on mutual understanding, take communication between patient and doctor as their starting point. According to this approach, autonomy requires a genuine dialogue, an interpersonal mode of being which we choose to call "authentic interaction". PMID:9873980

    2015-02-01

    In this paper the current findings to date of the Historic Building Information Model (HBIM) of the Four Courts in Dublin are presented. The Historic Building Information Model (HBIM) forms the basis for both structural and conservation analysis to measure the impact of war damage which still impacts on the building. The laser scan survey was carried out in the summer of 2014 of the internal and external structure. After registration and processing of the laser scan survey, the HBIM was created of the damaged section of the building and is presented as two separate workflows in this paper. The first is the model created from historic data, the second a procedural and segmented model developed from laser scan survey of the war damaged drum and dome. From both models structural damage and decay simulations will be developed for documentation and conservation analysis.

  15. Perspectives on contextual vulnerability in discourses of climate conflict

    2016-02-01

    The science of climate security and conflict is replete with controversies. Yet the increasing vulnerability of politically fragile countries to the security consequences of climate change is widely acknowledged. Although climate conflict reflects a continuum of conditional forces that coalesce around the notion of vulnerability, how different portrayals of vulnerability influence the discursive formation of climate conflict relations remains an exceptional but under-researched issue. This paper combines a systematic discourse analysis with a vulnerability interpretation diagnostic tool to explore (i) how discourses of climate conflict are constructed and represented, (ii) how vulnerability is communicated across discourse lines, and (iii) the strength of contextual vulnerability against a deterministic narrative of scarcity-induced conflict, such as that pertaining to land. Systematically characterising climate conflict discourses based on the central issues constructed, assumptions about mechanistic relationships, implicit normative judgements and vulnerability portrayals, provides a useful way of understanding where discourses differ. While discourses show a wide range of opinions "for" and "against" climate conflict relations, engagement with vulnerability has been less pronounced - except for the dominant context centrism discourse concerned about human security (particularly in Africa). In exploring this discourse, we observe an increasing sense of contextual vulnerability that is oriented towards a concern for complexity rather than predictability. The article concludes by illustrating that a turn towards contextual vulnerability thinking will help advance a constructivist theory-informed climate conflict scholarship that recognises historicity, specificity, and variability as crucial elements of contextual totalities of any area affected by climate conflict.

  18. Scientific Versus Experiential Evidence: Discourse Analysis of the Chronic Cerebrospinal Venous Insufficiency Debate in a Multiple Sclerosis Forum

    PubMed Central

    Weibezahl, Lara; Friede, Tim; Himmel, Wolfgang; Makedonski, Philip; Grabowski, Jens

    2015-01-01

    Background The vascular hypothesis of multiple sclerosis (MS), called chronic cerebrospinal venous insufficiency (CCSVI), and its treatment (known as liberation therapy) was immediately rejected by experts but enthusiastically gripped by patients who shared their experiences with other patients worldwide by use of social media, such as patient online forums. Contradictions between scientific information and lay experiences may be a source of distress for MS patients, but we do not know how patients perceive and deal with these contradictions. Objective We aimed to understand whether scientific and experiential knowledge were experienced as contradictory in MS patient online forums and, if so, how these contradictions were resolved and how patients tried to reconcile the CCSVI debate with their own illness history and experience. Methods By using critical discourse analysis, we studied CCSVI-related posts in the patient online forum of the German MS Society in a chronological order from the first post mentioning CCSVI to the time point when saturation was reached. For that time period, a total of 117 CCSVI-related threads containing 1907 posts were identified. We analyzed the interaction and communication practices of and between individuals, looked for the relation between concrete subtopics to identify more abstract discourse strands, and tried to reveal discourse positions explaining how users took part in the CCSVI discussion. Results There was an emotionally charged debate about CCSVI which could be generalized to 2 discourse strands: (1) the “downfall of the professional knowledge providers” and (2) the “rise of the nonprofessional treasure trove of experience.” The discourse strands indicated that the discussion moved away from the question whether scientific or experiential knowledge had more evidentiary value. Rather, the question whom to trust (ie, scientists, fellow sufferers, or no one at all) was of fundamental significance. Four discourse positions could be identified by arranging them into the dimensions “trust in evidence-based knowledge,” “trust in experience-based knowledge,” and “subjectivity” (ie, the emotional character of contributions manifested by the use of popular rhetoric that seemed to mask a deep personal involvement). Conclusions By critical discourse analysis of the CCSVI discussion in a patient online forum, we reconstruct a lay discourse about the evidentiary value of knowledge. We detected evidence criteria in this lay discourse that are different from those in the expert discourse. But we should be cautious to interpret this dissociation as a sign of an intellectual incapability to understand scientific evidence or a naïve trust in experiential knowledge. Instead, it might be an indication of cognitive dissonance reduction to protect oneself against contradictory information. PMID:26133525

  20. Use of historical information in extreme storm surges frequency analysis

    NASA Astrophysics Data System (ADS)

    Hamdi, Yasser; Duluc, Claire-Marie; Deville, Yves; Bardet, Lise; Rebour, Vincent

    2013-04-01

    The prevention of storm surge flood risks is critical for protection and design of coastal facilities to very low probabilities of failure. The effective protection requires the use of a statistical analysis approach having a solid theoretical motivation. Relating extreme storm surges to their frequency of occurrence using probability distributions has been a common issue since 1950s. The engineer needs to determine the storm surge of a given return period, i.e., the storm surge quantile or design storm surge. Traditional methods for determining such a quantile have been generally based on data from the systematic record alone. However, the statistical extrapolation, to estimate storm surges corresponding to high return periods, is seriously contaminated by sampling and model uncertainty if data are available for a relatively limited period. This has motivated the development of approaches to enlarge the sample extreme values beyond the systematic period. The nonsystematic data occurred before the systematic period is called historical information. During the last three decades, the value of using historical information as a nonsystematic data in frequency analysis has been recognized by several authors. The basic hypothesis in statistical modeling of historical information is that a perception threshold exists and that during a giving historical period preceding the period of tide gauging, all exceedances of this threshold have been recorded. Historical information prior to the systematic records may arise from high-sea water marks left by extreme surges on the coastal areas. It can also be retrieved from archives, old books, earliest newspapers, damage reports, unpublished written records and interviews with local residents. A plotting position formula, to compute empirical probabilities based on systematic and historical data, is used in this communication paper. The objective of the present work is to examine the potential gain in estimation accuracy with the use of historical information (to the Brest tide gauge located in the French Atlantic coast). In addition, the present work contributes to addressing the problem of the presence of outliers in data sets. Historical data are generally imprecise, and their inaccuracy should be properly accounted for in the analysis. However, as several authors believe, even with substantial uncertainty in the data, the use of historical information is a viable mean to improve estimates of rare events related to extreme environmental conditions. The preliminary results of this study suggest that the use of historical information increases the representativity of an outlier in the systematic data. It is also shown that the use of historical information, specifically the perception sea water level, can be considered as a reliable solution for the optimal planning and design of facilities to withstand extreme environmental conditions, which will occur during its lifetime, with an appropriate optimum of risk level. Findings are of practical relevance for applications in storm surge risk analysis and flood management.

  1. Perpetuating 'New Public Management' at the expense of nurses' patient education: a discourse analysis.

    PubMed

    Bergh, Anne-Louise; Friberg, Febe; Persson, Eva; Dahlborg-Lyckhage, Elisabeth

    2015-09-01

    This study aimed to explore the conditions for nurses' daily patient education work by focusing on managers' way of speaking about the patient education provided by nurses in hospital care. An explorative, qualitative design with a social constructionist perspective was used. Data were collected from three focus group interviews and analysed by means of critical discourse analysis. Discursive practice can be explained by the ideology of hegemony. Due to a heavy workload and lack of time, managers could 'see' neither their role as a supporter of the patient education provided by nurses, nor their role in the development of nurses' pedagogical competence. They used organisational, financial, medical and legal reasons for explaining their failure to support nurses' provision of patient education. The organisational discourse was an umbrella term for 'things' such as cost-effectiveness, which were prioritised over patient education. There is a need to remove managerial barriers to the professional development of nurses' patient education. Managers should be responsible for ensuring and overseeing that nurses have the prerequisites necessary for providing patient education as well as for enabling continuous reflective dialogue and opportunities for learning in practice.

    The nature of landfill-related information that can be derived from existing, or historic, aerial photographs, is reviewed. This information can be used for conducting temporal assessments of landfill existence, land use and land cover, and the physical environment. As such, analysis of low cost, readily available aerial photographs can provide important, objective input to landfill inventories, assessing contamination or health hazards, planning corrective measures, planning waste collection and facilities, and developing on inactive landfills.

  4. Home Healthcare and Family Responsibility: A Critical Discourse Analysis of Talk and Text

    PubMed Central

    Funk,, Laura M.

    2013-01-01

    This paper addresses how families' roles and responsibility for care are constructed within home health (in contrast to the responsibility of home health). A discourse analysis informed by a critical theoretical approach was used to analyze qualitative interviews with 13 home health managers and clinical leaders in British Columbia, alongside home care documents. When referring to family involvement, there was an emphasis on the importance of supporting a client's choice to stay at home. Government and agency documents describe family members as primary providers, with home health having a supplementary role. Agencies seek to avoid “substituting” for family care. Family responsibility is characterized as having both moral and structural value. Nonetheless, some participants advocated flexibility and recognized potential caregiving challenges. Data provide examples of how agency expectations are communicated to clients and families and become embedded within practice and policy. Findings are viewed within the broader organizational context as representing the “responsibilization” of support. PMID:24289942

    Wright, David Kenneth; Karsoho, Hadi; Sandham, Sarah; Macdonald, Mary Ellen

    2015-01-01

    Background Recent events in Canada have mobilized public debate concerning the controversial issue of euthanasia. Physicians represent an essential stakeholder group with respect to the ethics and practice of euthanasia. Further, their opinions can hold sway with the public, and their public views about this issue may further reflect back upon the medical profession itself. Methods We conducted a discourse analysis of print media on physicians’ perspectives about end-of-life care. Print media, in English and French, that appeared in Canadian newspapers from 2008 to 2012 were retrieved through a systematic database search. We analyzed the content of 285 articles either authored by a physician or directly referencing a physician’s perspective. Results We identified 3 predominant discourses about physicians’ public views toward euthanasia: 1) contentions about integrating euthanasia within the basic mission of medicine, 2) assertions about whether euthanasia can be distinguished from other end-of-life medical practices and 3) palliative care advocacy. Interpretation Our data showed that although some medical professional bodies appear to be supportive in the media of a movement toward the legalization of euthanasia, individual physicians are represented as mostly opposed. Professional physician organizations and the few physicians who have engaged with the media are de facto representing physicians in public contemporary debates on medical aid in dying, in general, and euthanasia, in particular. It is vital for physicians to be aware of this public debate, how they are being portrayed within it and its potential effects on impending changes to provincial and national policies. PMID:26389090

  2. Use of cartography in historical seismicity analysis: a reliable tool to better apprehend the contextualization of the historical documents

    NASA Astrophysics Data System (ADS)

    Thibault, Fradet; Grégory, Quenet; Kevin, Manchuel

    2014-05-01

    Historical studies, including historical seismicity analysis, deal with historical documents. Numerous factors, such as culture, social condition, demography, political situations and opinions or religious ones influence the way the events are transcribed in the archives. As a consequence, it is crucial to contextualize and compare the historical documents reporting on a given event in order to reduce the uncertainties affecting their analysis and interpretation. When studying historical seismic events it is often tricky to have a global view of all the information provided by the historical documents. It is also difficult to extract cross-correlated information from the documents and draw a precise historical context. Use of cartographic and geographic tools in GIS software is the best tool for the synthesis, interpretation and contextualization of the historical material. The main goal is to produce the most complete dataset of available information, in order to take into account all the components of the historical context and consequently improve the macroseismic analysis. The Entre-Deux-Mers earthquake (1759, Iepc= VII-VIII) [SISFRANCE 2013 - EDF-IRSN-BRGM] is well documented but has never benefited from a cross-analysis of historical documents and historical context elements. The map of available intensity data from SISFRANCE highlights a gap in macroseismic information within the estimated epicentral area. The aim of this study is to understand the origin of this gap by making a cartographic compilation of both, archive information and historical context elements. The results support the hypothesis that the lack of documents and macroseismic data in the epicentral area is related to a low human activity rather than low seismic effects in this zone. Topographic features, geographical position, flood hazard, roads and pathways locations, vineyards distribution and the forester coverage, mentioned in the archives and reported on the Cassini's map confirm this hypothesis. The location of the recently explored documentary sources evidence that there was no notarial activity in this particular area at that time. The importance of the economic and political dominance of Bordeaux during the XVIIth-XVIIIth centuries has to be taken into account in order to apprehend the way the earthquake was reported by the population at the regional scale. Elements related to chimneys forms or construction techniques could in turn help in identifying regional peculiarities allowing better quantifying the vulnerability aspects of the region.

    2008-03-01

    In order to be able to reproduce historic organ reed pipes, a bulk non-destructive chemical composition analysis was performed on the tongues and shallots, focusing mainly on the ratio between copper and zinc and on the presence of lead. Prompt gamma activation analysis results allowed us to observe for the first time that the ratio between the two main components of the brass alloy changed from Cu:Zn = 3:1 for the old tongues and shallots to Cu:Zn = 2:1 around the middle of the 18th century, which is typical also for the modern alloys offered to the organ builders nowadays. We also discovered that the Pb content in the old historic brass alloy diminished until the middle of 18th century when the brass alloy became mainly Pb free. The non-uniform lead distribution inside one of the shallots obtained from a prompt gamma activation analysis (PGAA) experiment was studied by neutron tomography. It gave us a three-dimensonal (3D) distribution of the lead inclusions inside the shallots. The lead particles are concentrated towards the base of the shallot.

  4. Expanding discourse repertoires with hybridity

    NASA Astrophysics Data System (ADS)

    Kelly, Gregory J.

    2012-09-01

    In "Hybrid discourse practice and science learning" Kamberelis and Wehunt present a theoretically rich argument about the potential of hybrid discourses for science learning. These discourses draw from different forms of "talk, social practice, and material practices" to create interactions that are "intertextually complex" and "interactionally dynamic." The hybrid discourse practices are described as involving the dynamic interplay of at least three key elements: "the lamination of multiple cultural frames, the shifting relations between people and their discourse, and the shifting power relations between and among people." Each of these elements requires a respective unit of analysis and are often mutually reinforcing. The authors present a theoretically cogent argument for the study of hybrid discourse practices and identify the potential such discourses may have for science education. This theoretical development leads to an analysis of spoken and written discourse around a set of educational events concerning the investigation of owl pellets by two fifth grade students, their classmates, and teacher. Two discourse segments are presented and analyzed by the authors in detail. The first is a discourse analysis of the dissection of the owl pellet by two students, Kyle and Max. The second analysis examines the science report of these same two students. In this article, I pose a number of questions about the study with the hope that by doing so I expand the conversation around the insightful analysis presented.

  5. 'Risk or Right': a discourse analysis of midwifery and obstetric colleges' homebirth position statements.

    PubMed

    Licqurish, Sharon; Evans, Alicia

    2016-03-01

    Within the context of global debates about safety and ethics of supporting women to give birth at home, it is important to analyse documents governing midwifery and obstetric practice and influence decision-making around place of birth. In Australia, the United States and the United Kingdom, relatively small numbers of women choose to give birth at home despite their midwifery colleges' support. In the United States and Australia, the obstetric colleges do not support homebirth and these countries have lower numbers of women who birth at home, compared with the United Kingdom. There are numerous regulatory and industry challenges for midwives attending homebirths. This paper reports on a Foucauldian analysis of Australian obstetric and midwifery colleges' position statements about homebirth, who have conflicting views, with the view to understanding their arguments and underlying assumptions. The documents highlighted tensions between competing discourses of risk and autonomy and differences in academic argument. Opportunities for strengthening their statements are highlighted. The methodology is applicable for future analysis of similar documents governing practice in other countries. PMID:26345985

    Terahertz (THz) spectroscopy and THz and imaging techniques are expected to have great potential for the non-invasive analysis of artworks. We have applied THz imaging to analyse the historic mural painting of a Lamaism temple by using a transportable time-domain THz imaging system; such an attempt is the first in the world. The reflection image revealed that there are two orange colours in the painting, although they appear the same to the naked eye. THz imaging can also estimate the depth of cracks. The colours were examined by X-ray fluorescence and Raman spectroscopy, and the results were found to be in good agreement. This work proved that THz imaging can contribute to the non-invasive analysis of cultural heritage.

    Background This paper describes and evaluates a sentence selection engine that extracts a GeneRiF (Gene Reference into Functions) as defined in ENTREZ-Gene based on a MEDLINE record. Inputs for this task include both a gene and a pointer to a MEDLINE reference. In the suggested approach we merge two independent sentence extraction strategies. The first proposed strategy (LASt) uses argumentative features, inspired by discourse-analysis models. The second extraction scheme (GOEx) uses an automatic text categorizer to estimate the density of Gene Ontology categories in every sentence; thus providing a full ranking of all possible candidate GeneRiFs. A combination of the two approaches is proposed, which also aims at reducing the size of the selected segment by filtering out non-content bearing rhetorical phrases. Results Based on the TREC-2003 Genomics collection for GeneRiF identification, the LASt extraction strategy is already competitive (52.78%). When used in a combined approach, the extraction task clearly shows improvement, achieving a Dice score of over 57% (+10%). Conclusions Argumentative representation levels and conceptual density estimation using Gene Ontology contents appear complementary for functional annotation in proteomics. PMID:18426554

  12. Environmental assessment in The Netherlands: Effectively governing environmental protection? A discourse analysis

    SciTech Connect

    2013-02-15

    Environmental assessment (EA) aims to enhance environmental awareness and to ensure that environmental values are fully considered in decision-making. In the EA arena, different discourses exist on what EA should aim for and how it functions. We hypothesise that these discourses influence its application in practice as well as its effectiveness in terms of achieving the above goals. For instance, actors who consider EA as a hindrance to fast implementation of their projects will probably apply it as a mandatory checklist, whereas actors who believe that EA can help to develop more environmentally sound decisions will use EIA as a tool to design their initiatives. In this paper we explore discourses on EA in The Netherlands and elaborate on their implications for EA effectiveness. Based on an innovative research design comprising an online survey with 443 respondents and 20 supplementary semi-structured interviews we conclude that the dominant discourse is that EA is mainly a legal requirement; EAs are conducted because they have to be conducted, not because actors choose to do so. EA effectiveness however seems reasonably high, as a majority of respondents perceive that it enhances environmental awareness and contributes to environmental protection. However, the 'legal requirement' discourse also results in decision-makers seldom going beyond what is prescribed by EA and environmental law. Despite its mandatory character, the predominant attitude towards EA is quite positive. For most respondents, EA is instrumental in providing transparency of decision-making and in minimising the legal risks of not complying with environmental laws. Differences in discourses seldom reflect extreme opposites. The 'common ground' regarding EA provides a good basis for working with EA in terms of meeting legal requirements but at the same time does not stimulate creativity in decision-making or optimisation of environmental values. In countries characterised by less consensual political cultures we may expect more extreme discourses on EA, the consequences of which are reflected upon in this paper. - Highlights: Black-Right-Pointing-Pointer The effectiveness of environmental assessment (EA) depends in part on meanings associated with EA (i.e., discourse). Black-Right-Pointing-Pointer Our results suggest that the general discourse in The Netherlands is that EA is a legal requirement, nothing more. Black-Right-Pointing-Pointer This discourse makes EA effective in protecting the environment, but not in the optimisation of environmental values. Black-Right-Pointing-Pointer EA has a limited contribution to the development of policy alternatives or innovative solutions to environmental problems. Black-Right-Pointing-Pointer There is a high consensus among EA professionals, providing a common ground for working with EA.

  15. The Invaluable and Irreplaceable Role of the Historical Seismograms' Analysis

    NASA Astrophysics Data System (ADS)

    Pino, N.

    2008-12-01

    Based on the general evidence that strongest events repeat on the major geological faults, often with similar features, the reconstruction of the pattern of energy release for the 1908 earthquake source is crucial for the assessment of the seismic risk in the region. At the beginning of the twentieth century, many seismic stations were operating in the world and at least 110 recorded the Messina Straits event. Since 1908, several seismologists analyzed the available seismograms aiming at the determination of earthquake source parameters, but their studies were strongly affected by the state of the seismological knowledge and the available technology. Today, after 100 years, taking advantage of the scientific and technological progress, historical seismograms can be reanalyzed with techniques analogue to those used in modern earthquake studies. Although most original seismograms of the 1908 earthquake are unfortunately lost, the analysis of the available waveforms allowed the reconstruction of the fault kinematics, putting firm and unique constraints not achievable with other investigations.

    The addition of proteinaceous binders to mortars and plasters has a long tradition. The protein additions were identified in many sacral and secular historical buildings. For this method of peptide mass mapping, three model mortar samples with protein additives were prepared. These samples were analysed fresh (1-2 weeks old) and after 9 months of natural ageing. The optimal duration of tryptic cleavage (2 h) and the lowest amount of material needed for relevant analysis of fresh and weathered samples were found; the sufficient amounts of weathered and fresh mortars were set to 0.05 and 0.005 g. The list of main tryptic peptides coming from milk additives (bovine milk, curd, and whey), their relative intensities and theoretical amino acid sequences assignment is presented. Several sequences have been "de novo" confirmed by mass spectrometry.

    2014-06-01

    Social-historical study aimed at discussing the nursing and psychiatric nurse models, from the discourses published in the Annals of Nursing.The historical sources were articles published in the Annals of Nursing journal, from 1933 to 1951. An analysis of the discourse was subsidized by the genealogy of power by Michel Foucault.The analysis showed that the discourse on nursing and the psychiatric nurse, in the first half of the 20th century, is set, on one side, by the propositions used by psychiatrists, who sought to reiterate stereotypes and vocations to practice nursing, and, on the other side, by the active participation of nurses seeking to legitimize expertise for psychiatric nursing. It was concluded that the discourses analyzed defined a psychiatric care focused on the nurse and not the rest of the nursing staff, at that time. PMID:25158460

    This study seeks to provide evidence of the dynamics associated with the configurations of discourse-voice regulatory strategies in patient–therapist interactions in relevant episodes within psychotherapeutic sessions. Its central assumption is that discourses manifest themselves differently in terms of their prosodic characteristics according to their regulatory functions in a system of interactions. The association between discourse and vocal quality in patients and therapists was analyzed in a sample of 153 relevant episodes taken from 164 sessions of five psychotherapies using the state space grid (SSG) method, a graphical tool based on the dynamic systems theory (DST). The results showed eight recurrent and stable discourse-voice regulatory strategies of the patients and three of the therapists. Also, four specific groups of these discourse-voice strategies were identified. The latter were interpreted as regulatory configurations, that is to say, as emergent self-organized groups of discourse-voice regulatory strategies constituting specific interactional systems. Both regulatory strategies and their configurations differed between two types of relevant episodes: Change Episodes and Rupture Episodes. As a whole, these results support the assumption that speaking and listening, as dimensions of the interaction that takes place during therapeutic conversation, occur at different levels. The study not only shows that these dimensions are dependent on each other, but also that they function as a complex and dynamic whole in therapeutic dialog, generating relational offers which allow the patient and the therapist to regulate each other and shape the psychotherapeutic process that characterizes each type of relevant episode.

    The field of discourse processing has dissected many of the levels of representation that are constructed when individuals read or listen to connected discourse. These levels include the surface code, the propositional textbase, the referential situation model, the communication context, and the discourse genre. Discourse psychologists have developed models that specify how these levels are mentally represented and how they are dynamically built during comprehension. This chapter focuses on the meaning representations that are constructed when adults read written text, such as literary stories, technical expository text, and experimenter-generated "textoids." Recent psychological models have attempted to account for the identification of referents of referring expressions (e.g. which person in the text does she refer to), the connection of explicit text segments, the establishment of local and global coherence, and the encoding of knowledge-based inferences.

  20. Teaching ethics in engineering education through historical analysis.

    PubMed

    Billington, David P

    2006-04-01

    The goal of this paper is to stress the significance of ethics for engineering education and to illustrate how it can be brought into the mainstream of higher education in a natural way that is integrated with the teaching objectives of enriching the core meaning of engineering. Everyone will agree that the practicing engineer should be virtuous, should be a good colleague, and should use professional understanding for the common good. But these injunctions to virtue do not reach closely enough the ethic of the engineer as engineer, as someone acting in a uniquely engineering situation, and it is to such conditions that I wish to speak through a set of specific examples from recent history. I shall briefly refer to four controversies between engineers. Then, in some detail I shall narrate three historical cases that directly involve the actions of one engineer, and finally I would like to address some common contemporary issues. The first section, Engineering Ethics and the History of Innovation, includes four cases involving professional controversy. Each controversy sets two people against each other in disputes over who invented the telegraph, the radio, the automobile, and the airplane. In each dispute, it is possible to identify ethical and unethical behavior or ambiguous ethical behavior that serves as a basis for educational discussion. The first two historical cases described in "Crises and the Engineer" involve the primary closure dam systems in The Netherlands, each one the result of the actions of one engineer. The third tells of an American engineer who took his political boss, a big city mayor, to court over the illegal use of a watershed. The challenges these engineers faced required, in the deepest sense, a commitment to ethical behavior that is unique to engineering and instructive to our students. Finally, the cases in "Professors and Comparative Critical Analysis" illuminate the behavior of engineers in the design of structures and also how professors can make public criticisms of designs that seem wasteful.

    Ercan, E.; Nuhoglu, A.

    2014-01-01

    This paper describes the results of a model updating study conducted on a historical aqueduct, called Veziragasi, in Turkey. The output-only modal identification results obtained from ambient vibration measurements of the structure were used to update a finite element model of the structure. For the purposes of developing a solid model of the structure, the dimensions of the structure, defects, and material degradations in the structure were determined in detail by making a measurement survey. For evaluation of the material properties of the structure, nondestructive and destructive testing methods were applied. The modal analysis of the structure was calculated by FEM. Then, a nondestructive dynamic test as well as operational modal analysis was carried out and dynamic properties were extracted. The natural frequencies and corresponding mode shapes were determined from both theoretical and experimental modal analyses and compared with each other. A good harmony was attained between mode shapes, but there were some differences between natural frequencies. The sources of the differences were introduced and the FEM model was updated by changing material parameters and boundary conditions. Finally, the real analytical model of the aqueduct was put forward and the results were discussed. PMID:24511287

    2002-12-01

    The 1930 Irpinia earthquake is one of the most destructive events recorded by instruments in Italy. Several large events occurred in the same area before (1456, 1694, 1702, 1732, 1910) and after (1962, 1980, 1983) 1930. It has been hypothesized that significant differences characterized the source geometry. Early work carried out by several authors on macroseismic studies and a single-station waveform analysis, suggests a quasi-strike slip mechanism on an approximately EW-oriented fault plain. Conversely, all the major events in the area display normal fault mechanisms on Apennine-oriented (NW-SE) fault planes. In the present work we have collected about 45 waveforms for the 1930 earthquake, recorded in various European observatories, aiming to find precious hints on source geometry and kinematics. The seismograms have been rasterized, digitized and processed within the framework of the SISMOS project. The study of this earthquake is part of a wider ongoing research program on the 20th century Irpinia earthquakes (1910, 1030, 1962 and 1980) within the collaboration between the TROMOS and SISMOS projects of the National Institute of Geophysics and Volcanology. The search and recovery of the historical recordings is a unique opportunity to shed light upon scientific aspects related to this kind of investigation. Preliminary results about the 1930 earthquake waveform analysis are presented here.

    We illustrate a numerical tool for analyzing plane arches such as those frequently used in historical masonry heritage. It is based on a refined elastic mechanical model derived from the isogeometric approach. In particular, geometry and displacements are modeled by means of non-uniform rational B-splines. After a brief introduction, outlining the basic assumptions of this approach and the corresponding modeling choices, several numerical applications to arches, which are typical of masonry structures, show the performance of this novel technique. These are discussed in detail to emphasize the advantage and potential developments of isogeometric analysis in the field of structural analysis of historical masonry buildings with complex geometries.

  13. A critical discourse analysis of British national newspaper representations of the academic level of nurse education: too clever for our own good?

    PubMed

    Gillett, Karen

    2012-12-01

    This critical discourse analysis examines articles about the academic level of nurse education that appeared in British national newspapers between 1999 and 2009. British newspaper journalists regularly attribute problems with recruitment into nursing and nursing care to the increasing academic nature of nurse education. It is impossible to separate discourse about nurse education from the wider nursing discourse. Many journalists laud a traditional and stereotypical construct of nurse identity and suggest that increasing nurse education produces nurses who are 'too clever to care'. This article argues that whilst nurses lack a voice in the National press, they have little input into the construction of newspaper discourse about nurse education and subsequently, limited influence on resulting public opinion, government policy and the morale of nurses.

    2009-01-01

    NASA's successful conduct of the Apollo Program greatly enhanced the prestige of the United States and remains broadly accepted as America's gift to all Mankind. NASA's accomplishments continue to amaze the world. With the Vision for Space Exploration (VSE) Americans once again tasked NASA to carry out a project that is expected to provide inspiration and economic stimulus to the United States and to the world. In preparation NASA has thoroughly examined space program precedents. There is, however, another precedent which has not been examined in this context but whose scope and environment in many ways parallel the VSE. This project was initiated by a team that had, ten years before, successfully completed an effort that, at a cost of $173 billion (in 2008 dollars), had pushed the envelope of technology, brought economic growth, established their country as the world leader in engineering, and been broadly accepted as that country's gift to all Mankind. The new project was again inspired by popular desire to enhance national prestige and make yet another major contribution to Humanity. This effort was predicted to require eight years and $156 billion (2008 dollars). However, after nine years and expenditures of 96% beyond the baseline, the project collapsed amid bankruptcy, political scandal, and criminal prosecution. This paper applies current project management metrics, such as earned value analysis, to review the strategic decisions in this historic failure and describe its ultimate collapse. Key mistakes are identified, and lessons are drawn which may prove useful in guiding the VSE.

  15. Perfect harmony: A mathematical analysis of four historical tunings

    NASA Astrophysics Data System (ADS)

    Page, Michael F.

    2004-10-01

    In Western music, a musical interval defined by the frequency ratio of two notes is generally considered consonant when the ratio is composed of small integers. Perfect harmony or an ``ideal just scale,'' which has no exact solution, would require the division of an octave into 12 notes, each of which would be used to create six other consonant intervals. The purpose of this study is to analyze four well-known historical tunings to evaluate how well each one approximates perfect harmony. The analysis consists of a general evaluation in which all consonant intervals are given equal weighting and a specific evaluation for three preludes from Bach's ``Well-Tempered Clavier,'' for which intervals are weighted in proportion to the duration of their occurrence. The four tunings, 5-limit just intonation, quarter-comma meantone temperament, well temperament (Werckmeister III), and equal temperament, are evaluated by measures of centrality, dispersion, distance, and dissonance. When all keys and consonant intervals are equally weighted, equal temperament demonstrates the strongest performance across a variety of measures, although it is not always the best tuning. Given C as the starting note for each tuning, equal temperament and well temperament perform strongly for the three ``Well-Tempered Clavier'' preludes examined. .

  17. Choice and compassion at the end of life: A critical analysis of recent English policy discourse.

    PubMed

    2015-07-01

    End of life care in England has recently been framed by two very different discourses. One (connected to advance care planning) promotes personal choice, the other promotes compassionate care; both are prominent in professional, policy and media settings. The article outlines the history of who promoted each discourse from 2008 to early 2015, when, why and how and this was done. Each discourse is then critically analysed from a standpoint that takes account of bodily decline, structural constraints, and human relationality. We focus on the biggest group of those nearing the end of their life, namely frail very old people suffering multiple conditions. In their care within contemporary healthcare organisations, choice becomes a tick box and compassion a commodity. Informed choice, whether at the end of life or in advance of it, does not guarantee the death the person wants, especially for those dying of conditions other than cancer and in the absence of universally available skilled and compassionate care. Enabling healthcare staff to provide compassionate, relational care, however, implies reversing the philosophical, political and financial direction of healthcare in the UK and most other Anglophone countries.

    2015-01-01

    Background Integrative health care (IHC) combines therapies and providers from complementary and conventional health care. Previous studies on IHC have shown power relations between providers but few studies have explored how the interaction develops over time. The objective of this study was to explore the development of IHC collaboration and interaction among participating providers during a series of consensus case conferences for managing patients with back and neck pain. Methods This qualitative study was conducted within a pragmatic randomized controlled clinical trial in primary care. Patients' treatment plans were developed based on IHC provider consensus conferences (n = 26) of which 15 (5 of the first, 5 in the middle, and 5 of the last in the clinical trial) were selected for analysis. Findings were derived by means of discourse analysis, focusing on the participants’ use of subject positions during the conferences. Findings The IHC team in this study gradually formed a group identity, moving their subject positions from individual treating subjects to members of a team and were able to make consensus-based decisions about patients’ individual treatment plans. In the discourse, the IHC team identified collaborative shortcomings and problematized the provision of IHC. They were able to capitalize on the synergies in their collaboration and developed a shared vision of IHC provision. Conclusions The process of IHC collaboration involved the gradual formation of an IHC team identity, which facilitated interdisciplinary, non-hierarchical consensus-based decision-making in the team. The discourse further suggests that a reform of some legal and organizational health sector barriers might be needed to realize sustainable implementation of IHC services in Sweden. PMID:25793967

    The construction-integration model (Kintsch, 1988) offers a frame for discourse analysis. This model defines four representation levels: the surface level or linguistic form, the base text or semantic level, the situation model built by combining information from the text and personal world knowledge, and the organization level. This study describes discourse produced by 46 Alzheimer patients and 53 normal elderly subjects in two picture-elicited production tasks: a single picture and a sequence of pictures. Globally, the single picture task is a more difficult situation for Alzheimer patients. The impaired levels in dementia are surface level, situation model and organization. Therefore, Kintsch model allows a distinction among discourse productions by normal elderly and mild to moderate Alzheimer patients. PMID:15929926

    2013-04-01

    A computer program, Historical Observation Tools (HOB Tools), has been developed to facilitate many of the calculations used by historical climatologists to develop instrumental and documentary temperature and precipitation datasets and makes them readily accessible to other researchers. The primitive methodology used by the early weather observers makes the application of standard techniques difficult. HOB Tools provides a step-by-step framework to visually and statistically assess, adjust, and reconstruct historical temperature and precipitation datasets. These routines include the ability to check for undocumented discontinuities, adjust temperature data for poor thermometer exposures and diurnal averaging, and assess and adjust daily precipitation data for undercount. This paper provides an overview of the Visual Basic.NET program and a demonstration of how it can assist in the development of extended temperature and precipitation datasets using modern and early instrumental measurements from the United States.

    2015-09-01

    Patient education materials have the potential to strengthen the health literacy of patients. Previous studies indicate that readability and suitability may be improved. The aim of this study was to explore and analyze discourses inherent in patient education materials since analysis of discourses could illuminate values and norms inherent in them. Clinics in Sweden that provided colorectal cancer surgery allowed access to written information and 'welcome letters' sent to patients. The material was analysed by means of discourse analysis, embedded in Derrida's approach of deconstruction. The analysis revealed a biomedical discourse and a hospitality discourse. In the biomedical discourse, the subject position of the personnel was interpreted as the messenger of medical information while that of the patients as the carrier of diagnoses and recipients of biomedical information. In the hospitality discourse, the subject position of the personnel was interpreted as hosts who invite and welcome the patients as guests. The study highlights the need to eliminate paternalism and fosters a critical reflective stance among professionals regarding power and paternalism inherent in health care communication.

    2014-01-01

    Uganda is recognised as an early success story in the HIV epidemic at least in part due to an open and vigorous national dialogue about HIV prevention. This study examined the national discourse about HIV, AIDS, and young people in New Vision, Uganda's leading national newspaper between 1996 and 2011, building from a previous archival analysis of New Vision reporting by Kirby (1986-1995). We examined the continuing evolution in the public discourse in Uganda, focusing on reporting about young people. An increase in reporting on HIV and AIDS occurred after 2003, as antiretroviral treatment was becoming available. While the emphasis in newspaper reporting about adults and the population at large evolved to reflect the development of new HIV treatment and prevention methods, the majority of the articles focused on young people did not change. Articles about young people continued to emphasise HIV acquisition due to early and premarital sexual activity and the need for social support services for children affected by HIV and AIDS. Articles often did not report on the complex social conditions that shape HIV-related risk among young people, or address young people who are sexually active, married, and/or HIV infected. With HIV prevalence now increasing among young people and adults in Uganda, greater attention to HIV prevention is needed. PMID:25132802

  13. History of Science in the Physics Curriculum: A Directed Content Analysis of Historical Sources

    NASA Astrophysics Data System (ADS)

    Seker, Hayati; Guney, Burcu G.

    2012-05-01

    Although history of science is a potential resource for instructional materials, teachers do not have a tendency to use historical materials in their lessons. Studies showed that instructional materials should be adaptable and consistent with curriculum. This study purports to examine the alignment between history of science and the curriculum in the light of the facilitator model on the use of history of science in science teaching, and to expose possible difficulties in preparing historical materials. For this purpose, qualitative content analysis method was employed. Codes and themes were defined beforehand, with respect to levels and their sublevels of the model. The analysis revealed several problems with the alignment of historical sources for the physics curriculum: limited information about scientists' personal lives, the difficulty of linking with content knowledge, the lack of emphasis on scientific process in the physics curriculum, differences between chronology and sequence of topics, the lack of information about scientists' reasoning. Based on the findings of the analysis, it would be difficult to use original historical sources; educators were needed to simplify historical knowledge within a pedagogical perspective. There is a need for historical sources, like Harvard Case Histories in Experimental Science, since appropriate historical information to the curriculum objectives can only be obtained by simplifying complex information at the origin. The curriculum should leave opportunities for educators interested in history of science, even historical sources provides legitimate amount of information for every concepts in the curriculum.

  14. Themes relating to sexuality that emerged from a discourse analysis of the Nursing Times during 1980-1990.

    PubMed

    Carr, G

    1996-07-01

    The intention of this study was to develop insight into how the concept of human sexuality has been addressed within a popular nursing medium, namely the publication Nursing Times, during the decade 1980-1990. The study begins by clarifying discourse analysis and its role in the social construction of language. Exploration of the use of metaphors within nursing text is made to highlight the ability to convey multiple meaning and ideology within nursing practice. The 86 text papers generated during this decade were subjected to a process of qualitative data analysis entitled 'Framework'. The emerging themes from this process were used to inform a discussion of the ideological and practice relationships that exist between nursing and human sexuality. PMID:8807396

  18. Historical analysis of Newfoundland dog fur colour genetics

    PubMed Central

    Bondeson, J.

    2015-01-01

    This article makes use of digitized historic newspapers to analyze Newfoundland dog fur colour genetics, and fur colour variations over time. The results indicate that contrary to the accepted view, the ‘Solid’ gene was introduced into the British population of Newfoundland dogs in the 1840s. Prior to that time, the dogs were white and black (Landseer) or white and brown, and thus spotted/spotted homozygotes. Due to ‘Solid’ being dominant over ‘spotted’, and selective breeding, today the majority of Newfoundland dogs are solid black. Whereas small white marks on the chest and/or paw appears to be a random event, the historical data supports the existence of an ‘Irish spotted’ fur colour pattern, with white head blaze, breast, paws and tail tip, in spotted/spotted homozygotes.

  19. Flood frequency analysis - the challenge of using historical data

    NASA Astrophysics Data System (ADS)

    Engeland, Kolbjorn

    2015-04-01

    Estimates of high flood quantiles are needed for many applications, .e.g. dam safety assessments are based on the 1000 years flood, whereas the dimensioning of important infrastructure requires estimates of the 200 year flood. The flood quantiles are estimated by fitting a parametric distribution to a dataset of high flows comprising either annual maximum values or peaks over a selected threshold. Since the record length of data is limited compared to the desired flood quantile, the estimated flood magnitudes are based on a high degree of extrapolation. E.g. the longest time series available in Norway are around 120 years, and as a result any estimation of a 1000 years flood will require extrapolation. One solution is to extend the temporal dimension of a data series by including information about historical floods before the stream flow was systematically gaugeded. Such information could be flood marks or written documentation about flood events. The aim of this study was to evaluate the added value of using historical flood data for at-site flood frequency estimation. The historical floods were included in two ways by assuming: (1) the size of (all) floods above a high threshold within a time interval is known; and (2) the number of floods above a high threshold for a time interval is known. We used a Bayesian model formulation, with MCMC used for model estimation. This estimation procedure allowed us to estimate the predictive uncertainty of flood quantiles (i.e. both sampling and parameter uncertainty is accounted for). We tested the methods using 123 years of systematic data from Bulken in western Norway. In 2014 the largest flood in the systematic record was observed. From written documentation and flood marks we had information from three severe floods in the 18th century and they were likely to exceed the 2014 flood. We evaluated the added value in two ways. First we used the 123 year long streamflow time series and investigated the effect of having several shorter series' which could be supplemented with a limited number of known large flood events. Then we used the three historical floods from the 18th century combined with the whole and subsets of the 123 years of systematic observations. In the latter case several challenges were identified: i) The possibility to transfer water levels to river streamflows due to man made changes in the river profile, (ii) The stationarity of the data might be questioned since the three largest historical floods occurred during the "little ice age" with different climatic conditions compared to today.

  20. Analysis of Student-Instructor Interaction Patterns in Real-Time, Scientific Online Discourse

    Epp, Erik M.; Green, Kellie F.; Rahman, Aliya M.; Weaver, Gabriela C.

    2010-02-01

    The characteristics of the online environment alter how students and instructors interact. Scientific discourse among students and instructors in an online text-only synchronous environment was analyzed. In converting dialogue to text, many of the nonverbal cues, such as facial expression and tone of voice, which instructors use to gauge student understanding are lost. The participants adapt their communication style to the medium, and we present a new interaction pattern for student-instructor communication found prevalent in the synchronous, text-only, online environment. This study has implications for instructors who use synchronous, text-based communication for their courses, namely the value of posing additional questions from the instructor to verify student understanding.

  1. Professional caregivers' work with the dying in nursing homes--a Foucault-inspired analysis of discourses in the last decade in a Danish context.

    PubMed

    Nielsen, Karen T; Glasdam, Stinne

    2013-12-01

    International studies on the death of elderly nursing home residents show the complexity in the understanding of the professionals who care for the dying. The aim of this study is to explore the discourses about professional caregivers caring for those dying in Denmark in the last decade. A discourse analysis inspired by Foucault was constructed. The material consists of different source documents: research articles, newspaper articles, theses, books, websites - 35 sources in total. There are constructed six positions of speech, five discourses and three themes: (1) 'the work of the professional caregivers - a complex low-status work'; (2) 'the education of the professionals - the way to ensure a good death or possessing the right qualifications' and (3) 'the vulnerable professionals'. The study concludes that an economical/political discourse is dominating and sets up the frames within which the professionals care for dying residents, although the medical, the social/critical and the religious discourses attempt to speak against it. All positions articulate that the professional caregivers' job has a low status and that it is not possible to provide an optimal care due to lack of time, resources and education. Psychical or mental demands make the professionals vulnerable. The meaning of optimal care varies according to the positions of speech. PMID:23336738

    Peters, Lee B.; Bodenreider, Olivier

    2015-01-01

    Objective To investigate approaches to supporting the analysis of historical medication datasets with RxNorm. Methods We created two sets of National Drug Codes (NDCs). One is based on historical NDCs harvested from versions of RxNorm from 2007 to present. The other comprises all sources of NDCs in the current release of RxNorm, including proprietary sources. We evaluated these two resources against four sets of NDCs obtained from various sources. Results: In two historical medication datasets, 14–19% of the NDCs were obsolete, but 91–96% of these obsolete NDCs could be recovered and mapped to active drug concepts. Conclusion: Adding historical data significantly increases NDC mapping to active RxNorm drugs. A service for mapping historical NDC datasets leveraging RxNorm was added to the RxNorm API and is available at https://rxnav.nlm.nih.gov/. PMID:26958241

    Valuable information about the evolution of solar activity is recorded in early sunspot drawings, especially during 17th-19th centuries. In this context, we have developed a computer program to analyze historical drawings showing the trajectories of sunspots across the solar disk. As an example, we have analysed the drawings published in the book De heliometri structura et usu by Zucconi (1760). These drawings span the period from April 1754 to June 1760. We present the Butterfly diagram for those years. The ending of solar cycle 0 and the beginning of solar cycle 1 are clearly noted in this diagram.

  8. SI Engine Trends: A Historical Analysis with Future Projections

    SciTech Connect

    Pawlowski, Alexander; Splitter, Derek A

    2015-01-01

    It is well known that spark ignited engine performance and efficiency is closely coupled to fuel octane number. The present work combines historical and recent trends in spark ignition engines to build a database of engine design, performance, and fuel octane requirements over the past 80 years. The database consists of engine compression ratio, required fuel octane number, peak mean effective pressure, specific output, and combined unadjusted fuel economy for passenger vehicles and light trucks. Recent trends in engine performance, efficiency, and fuel octane number requirement were used to develop correlations of fuel octane number utilization, performance, specific output. The results show that historically, engine compression ratio and specific output have been strongly coupled to fuel octane number. However, over the last 15 years the sales weighted averages of compression ratios, specific output, and fuel economy have increased, while the fuel octane number requirement has remained largely unchanged. Using the developed correlations, 10-year-out projections of engine performance, design, and fuel economy are estimated for various fuel octane numbers, both with and without turbocharging. The 10-year-out projection shows that only by keeping power neutral while using 105 RON fuel will allow the vehicle fleet to meet CAFE targets if only the engine is relied upon to decrease fuel consumption. If 98 RON fuel is used, a power neutral fleet will have to reduce vehicle weight by 5%.

    2014-12-01

    Seeing how current agrometerological conditions measure up to historic events helps analysts and decision-makers judge the potential impact that anomalous rainfall and temperatures will have on the availability and accessibility of food and water resources. We present results from the Famine Early Warning Systems Network (FEWS NET) Land Data Assimilation System (FLDAS), which is used to produce multi-model and rainfall ensembles of the water balance over semi-arid Africa from 1982-2014. The ensemble approach allows us to assess confidence in our estimates, which is critical given that food and water insecure regions in Africa are data-poor are characterized by complex interactions and feedbacks that cause deterministic hydrologic modeling approaches to fall short. We then use the ensemble of water balance estimates to calculate drought severity (derived from modeled soil moisture), and the Water Requirement Satisfaction Index (a function of atmospheric water demand). We compare these indices to the GIMMS 30-year vegetation data product from AVHRR, and the ESA ECV 30 year microwave soil moisture. These historical time series (with confidence bounds) allow us to improve our quantitative understanding of drought thresholds, to explore sources of parameter and model uncertainty, and to better contextualize current operational drought monitoring efforts in Africa.

  2. Historical Material Analysis of DC745U Pressure Pads

    Ortiz-Acosta, Denisse

    2012-07-30

    As part of the Enhance Surveillance mission, it is the goal to provide suitable lifetime assessment of stockpile materials. This report is an accumulation of historical publication on the DC745U material and their findings. It is the intention that the B61 LEP program uses this collection of data to further develop their understanding and potential areas of study. DC745U is a commercially available silicone elastomer consisting of dimethyl, methyl-phenyl, and methyl-vinyl siloxane repeat units. Originally, this material was manufactured by Dow Corning as Silastic{reg_sign} DC745U at their manufacturing facility in Kendallville, IN. Recently, Dow Corning shifted this material to the Xiameter{reg_sign} brand product line. Currently, DC745U is available through Xiameter{reg_sign} or Dow Corning's distributor R. D. Abbott Company. DC745U is cured using 0.5 wt% vinyl-specific peroxide curing agent known as Luperox 101 or Varox DBPH-50. This silicone elastomer is used in numerous parts, including two major components (outer pressure pads and aft cap support) in the W80 and as pressure pads on the B61. DC745U is a proprietary formulation, thus Dow Corning provides limited information on its composition and properties. Based on past experience with Dow Corning, DC745U is at risk of formulation changes without notification to the costumer. A formulation change for DC745U may have a significant impact because the network structure is a key variable in determining material properties. The purpose of this report is to provide an overview of historical DC745U studies and identify gaps that need to be addressed in future work. Some of the previous studies include the following: 1. Spectroscopic characterization of raw gum stock. 2. Spectroscopic, thermal, and mechanical studies on cured DC745U. 3. Nuclear Magnetic Resonance (NMR) and solvent swelling studies on DC745U with different crosslink densities. 4. NMR, solvent swelling, thermal, and mechanical studies on thermally aged DC745U. 5. NMR, solvent swelling, thermal, and mechanical studies on radiolytically aged DC745U. Each area is reviewed and further work is suggested to improve our understanding of DC745U for systems engineering, surveillance, aging assessments, and lifetime assessment.

  3. Pedagogic discourse in introductory classes: Multi-dimensional analysis of textbooks and lectures in biology and macroeconomics

    NASA Astrophysics Data System (ADS)

    Carkin, Susan

    The broad goal of this study is to represent the linguistic variation of textbooks and lectures, the primary input for student learning---and sometimes the sole input in the large introductory classes which characterize General Education at many state universities. Computer techniques are used to analyze a corpus of textbooks and lectures from first-year university classes in macroeconomics and biology. These spoken and written variants are compared to each other as well as to benchmark texts from other multi-dimensional studies in order to examine their patterns, relations, and functions. A corpus consisting of 147,000 words was created from macroeconomics and biology lectures at a medium-large state university and from a set of nationally "best-selling" textbooks used in these same introductory survey courses. The corpus was analyzed using multi-dimensional methodology (Biber, 1988). The analysis consists of both empirical and qualitative phases. Quantitative analyses are undertaken on the linguistic features, their patterns of co-occurrence, and on the contextual elements of classrooms and textbooks. The contextual analysis is used to functionally interpret the statistical patterns of co-occurrence along five dimensions of textual variation, demonstrating patterns of difference and similarity with reference to text excerpts. Results of the analysis suggest that academic discourse is far from monolithic. Pedagogic discourse in introductory classes varies by modality and discipline, but not always in the directions expected. In the present study the most abstract texts were biology lectures---more abstract than written genres of academic prose and more abstract than introductory textbooks. Academic lectures in both disciplines, monologues which carry a heavy informational load, were extremely interactive, more like conversation than academic prose. A third finding suggests that introductory survey textbooks differ from those used in upper division classes by being relatively less marked for information density, abstraction, and non-overt argumentation. In addition to the findings mentioned here, numerous other relationships among the texts exhibit complex patterns of variation related to a number of situational variables. Pedagogical implications are discussed in relation to General Education courses, differing student populations, and the reading and listening demands which students encounter in large introductory classes in the university.

    Even if references to the tools required to intervene after an accident can be found in the works of Bernardino Ramazzini (1633-1714) or Johann Peter Frank (1745-1821), it was only with the development of industrial manufacturing that the need to study means to prevent and intervene in cases of accident became evident. In October 1894 the III Congrés International des Accidents du Travail et des Assurances Sociales was held in Milan. The following year, the Milanese trade union movement acknowledged the necessity to address the problem of industrial accidents. In 1896 the Association for Medical Assistance in  Industrial Accidents was founded in Milan. A specific medical institute was set up, appropriate first aid tools were collected and first aid rooms in the main Milanese factories were inaugurated. Nevertheless, few data seem to be available regarding the manufacture and use of this equipment in industry. We analyzed more than fifty catalogs of European industrial products, between 1843 and 1914, to study the evolution of first aid equipment for industrial use. They reflect and attest to the evolution of medicine and surgery, although some models seem to be related to certain industrial categories (railways, electrical appliances), some were similar to ordinary first aid boxes, others were strictly related to surgery; some could only be used by physicians, and others only by workers. Identification, conservation, and reappraisal of these tools is essential for historians of occupational health because these objects were normally not preserved. The catalogues of industrial production are also precious sources, since they are rarely preserved in public libraries and deserve to be used for historical studies. PMID:25607287

    2014-01-01

    Objectives Human pathogen richness and prevalence vary widely across the globe, yet we know little about whether global patterns found in other taxa also predict diversity in this important group of organisms. This study (a) assesses the relative importance of temperature, precipitation, habitat diversity, and population density on the global distributions of human pathogens and (b) evaluates the species-area predictions of island biogeography for human pathogen distributions on oceanic islands. Methods Historical data were used in order to minimize the influence of differential access to modern health care on pathogen prevalence. The database includes coded data (pathogen, environmental and cultural) for a worldwide sample of 186 non-industrial cultures, including 37 on islands. Prevalence levels for 10 pathogens were combined into a pathogen prevalence index, and OLS regression was used to model the environmental determinants of the prevalence index and number of pathogens. Results Pathogens (number and prevalence index) showed the expected latitudinal gradient, but predictors varied by latitude. Pathogens increased with temperature in high-latitude zones, while mean annual precipitation was a more important predictor in low-latitude zones. Other environmental factors associated with more pathogens included seasonal dry extremes, frost-free climates, and human population density outside the tropics. Islands showed the expected species-area relationship for all but the smallest islands, and the relationship was not mediated by habitat diversity. Although geographic distributions of free-living and parasitic taxa typically have different determinants, these data show that variables that influence the distribution of free-living organisms also shape the global distribution of human pathogens. Understanding the cause of these distributions is potentially important, since geographical variation in human pathogens has an important influence on global disparities in human welfare.

    Results from clinical trials are never interpreted in isolation. Previous studies in a similar setting provide valuable information for designing a new trial. For the analysis, however, the use of trial-external information is challenging and therefore controversial, although it seems attractive from an ethical or efficiency perspective. Here, we consider the formal use of historical control data on lesion counts in a multiple sclerosis trial. The approach to incorporating historical data is Bayesian, in that historical information is captured in a prior that accounts for between-trial variability and hence leads to discounting of historical data. We extend the meta-analytic-predictive approach, a random-effects meta-analysis of historical data combined with the prediction of the parameter in the new trial, from normal to overdispersed count data of individual-patient or aggregate-trial format. We discuss the prior derivation for the lesion mean count in the control group of the new trial for two populations. For the general population (without baseline enrichment), with 1936 control patients from nine historical trials, between-trial variability was moderate to substantial, leading to a prior effective sample size of about 45 control patients. For the more homogenous population (with enrichment), with 412 control patients from five historical trials, the prior effective sample size was approximately 63 patients. Although these numbers are small relative to the historical data, they are fairly typical in settings where between-trial heterogeneity is moderate. For phase II, reducing the number of control patients by 45 or by 63 may be an attractive option in many multiple sclerosis trials. PMID:23722585

  11. Historical remarks on exponential product and quantum analysis

    SciTech Connect

    Suzuki, Masuo

    2015-03-10

    The exponential product formula [1, 2] was substantially introduced in physics by the present author [2]. Its systematic applications to quantum Monte Carlo Methods [3] were preformed [4, 5] first in 1977. Many interesting applications [6] of the quantum-classical correspondence (namely S-T transformation) have been reported. Systematic higher-order decomposition formulae were also discovered by the present author [7-11], using the recursion scheme [7, 9]. Physically speaking, these exponential product formulae play a conceptual role of separation of procedures [3,14]. Mathematical aspects of these formulae have been integrated in quantum analysis [15], in which non-commutative differential calculus is formulated and a general quantum Taylor expansion formula is given. This yields many useful operator expansion formulae such as the Feynman expansion formula and the resolvent expansion. Irreversibility and entropy production are also studied using quantum analysis [15].

  12. Historical analysis of US pipeline accidents triggered by natural hazards

    2015-04-01

    Natural hazards, such as earthquakes, floods, landslides, or lightning, can initiate accidents in oil and gas pipelines with potentially major consequences on the population or the environment due to toxic releases, fires and explosions. Accidents of this type are also referred to as Natech events. Many major accidents highlight the risk associated with natural-hazard impact on pipelines transporting dangerous substances. For instance, in the USA in 1994, flooding of the San Jacinto River caused the rupture of 8 and the undermining of 29 pipelines by the floodwaters. About 5.5 million litres of petroleum and related products were spilled into the river and ignited. As a results, 547 people were injured and significant environmental damage occurred. Post-incident analysis is a valuable tool for better understanding the causes, dynamics and impacts of pipeline Natech accidents in support of future accident prevention and mitigation. Therefore, data on onshore hazardous-liquid pipeline accidents collected by the US Pipeline and Hazardous Materials Safety Administration (PHMSA) was analysed. For this purpose, a database-driven incident data analysis system was developed to aid the rapid review and categorization of PHMSA incident reports. Using an automated data-mining process followed by a peer review of the incident records and supported by natural hazard databases and external information sources, the pipeline Natechs were identified. As a by-product of the data-collection process, the database now includes over 800,000 incidents from all causes in industrial and transportation activities, which are automatically classified in the same way as the PHMSA record. This presentation describes the data collection and reviewing steps conducted during the study, provides information on the developed database and data analysis tools, and reports the findings of a statistical analysis of the identified hazardous liquid pipeline incidents in terms of accident dynamics and consequences.

  13. Historical analysis of professionalism in western societies: implications for interprofessional education and collaborative practice.

    Health care systems around the world are under tremendous pressure to change their models of health care delivery - from the current multiprofessional health care delivery into interprofessional collaborative care models with the ultimate goal of improving patient/client outcomes. The growing diversity of the population, the increasing number of vulnerable persons (elderly, homeless, those living with chronic health conditions), the complexity of health problems, and the shortage of health care providers have forced health policymakers to call for sweeping revisions to how health care is provided, impacting how health care program students are educated. However, in professional training emphasis is placed on uniprofessional education. Learners are socialized in isolation from those in other related professions to ensure the development of a shared professional identity. Consequently, by program completion each student will not only master the knowledge, skills and norms of his/her own profession, but will also develop a silo identity, called "uniprofessional identity". This isolationist identity creates a lack of understanding of others. In limiting their exposure to learning about the roles and value of other health care professionals, persistent negative stereotypical attitudes towards other professionals are reinforced. In this paper, we present the historical evolution(s) of the discourse of professionalism to assist us to develop a deeper understanding of socio-historical context within which interprofessional education (IPE) is embedded within, and collaborative person-centered practice (CPCP). With greater insight, we can (re)conceptualize the possibilities, and advance research on, interprofessional education and practice in the present. PMID:24383410

  16. A network-base analysis of CMIP5 "historical" experiments

    2012-12-01

    In computer science, "complex network analysis" refers to a set of metrics, modeling tools and algorithms commonly used in the study of complex nonlinear dynamical systems. Its main premise is that the underlying topology or network structure of a system has a strong impact on its dynamics and evolution. By allowing to investigate local and non-local statistical interaction, network analysis provides a powerful, but only marginally explored, framework to validate climate models and investigate teleconnections, assessing their strength, range, and impacts on the climate system. In this work we propose a new, fast, robust and scalable methodology to examine, quantify, and visualize climate sensitivity, while constraining general circulation models (GCMs) outputs with observations. The goal of our novel approach is to uncover relations in the climate system that are not (or not fully) captured by more traditional methodologies used in climate science and often adopted from nonlinear dynamical systems analysis, and to explain known climate phenomena in terms of the network structure or its metrics. Our methodology is based on a solid theoretical framework and employs mathematical and statistical tools, exploited only tentatively in climate research so far. Suitably adapted to the climate problem, these tools can assist in visualizing the trade-offs in representing global links and teleconnections among different data sets. Here we present the methodology, and compare network properties for different reanalysis data sets and a suite of CMIP5 coupled GCM outputs. With an extensive model intercomparison in terms of the climate network that each model leads to, we quantify how each model reproduces major teleconnections, rank model performances, and identify common or specific errors in comparing model outputs and observations.

    The subflorescence and efflorescence phenomena are widely acknowledged as the major causes of permanent damage to fresco wall paintings. They are related to the occurrence of cycles of dry/wet conditions inside the walls. Therefore, it is essential to identify the presence of water on the decorated surfaces and inside the walls. Nondestructive testing in industrial applications have confirmed that active infrared thermography with continuous timed images acquisition can improve the outcomes of thermal analysis aimed to moisture identification. In spite of that, in cultural heritage investigations these techniques have not been yet used extensively on a regular basis. This paper illustrates an application of these principles in order to evaluate the decay of fresco mural paintings in a medieval chapel located in North-West of Italy. One important feature of this study is the use of a robotic system called aIRview that can be utilized to automatically acquire and process thermal images. Multiple accurate thermal views of the inside walls of the building have been produced in a survey that lasted several days. Signal processing algorithms based on Fast Fourier Transform analysis have been applied to the acquired data in order to formulate trustworthy hypotheses about the deterioration mechanisms.

    Dahlborg-Lyckhage, Elisabeth; Pilhammar-Anderson, Ewa

    2009-05-01

    The aim of this study was to elucidate the predominant discourse in the field of Swedish nursing in 2000, 25 years after nursing was introduced as an academic discipline in Sweden. The method used was content analysis and deconstructive analysis of discourses. Laws, statutes, regulations, and examination requirements, including official reports, recruitment campaigns, and media coverage, were analyzed. The findings uncovered competing discourses striving to gain hegemony. In the public sector, official requirements competed against the media fixation on gender stereotypes and the realities of local recruitment campaigns. Media has a major role in disseminating prevailing conceptions and conventions pertaining to the nursing profession. As a result, decision makers, students, patients, and family members could get lower expectations of the professional competence of nursing practitioners than would otherwise have been the case in the absence of media exposure.

    Background: Considering the cognitive and linguistic complexity of discourse production, it is expected that individuals with traumatic brain injury (TBI) should face difficulties in this task. Therefore, clinical examination of discourse has become a useful tool for studying and assessment of communication skills of people suffering from TBI. Among different genres of discourse, persuasive discourse is considered as a more cognitively demanding task. However, little is known about persuasive discourse in individuals suffering from TBI. Objectives: The purpose of this study was to evaluate the performance of adults with TBI on a task of spoken persuasive discourse to determine the impaired linguistic measures. Patients and Methods: Thirteen TBI nonaphasic Persian speaking individuals, ranged between 19 to 40 years (Mean = 25.64 years; SD = 6.10) and 59 healthy adults matched by age, were asked to perform the persuasive discourse task. The task included asking the participants to express their opinion on a topic, and after the analysis of the produced discourse, the two groups were compared on the basis of their language productivity, sentential complexity, maze ratio and cohesion ratio. Results: The TBI group produced discourses with less productivity, sentential complexity, cohesion ratio and more maze ratio compared the control group. Conclusions: As it is important to consider acquired communication disorders particularly discourse impairment of brain injured patients along with their other clinical impairments and regarding the fact that persuasive discourse is crucial in academic and social situations, the persuasive discourse task presented in this study could be a useful tool for speech therapists, intending to evaluate communication disorders in patients with TBI.

  9. Analysis of historical delta values for IAEA/LANL NDA training courses

    The Los Alamos National Laboratory (LANL) supports the International Atomic Energy Agency (IAEA) by providing training for IAEA inspectors in neutron and gamma-ray Nondestructive Assay (NDA) of nuclear material. Since 1980, all new IAEA inspectors attend this two week course at LANL gaining hands-on experience in the application of NDA techniques, procedures and analysis to measure plutonium and uranium nuclear material standards with well known pedigrees. As part of the course the inspectors conduct an inventory verification exercise. This exercise provides inspectors the opportunity to test their abilities in performing verification measurements using the various NDA techniques. For an inspector, the verification of an item is nominally based on whether the measured assay value agrees with the declared value to within three times the historical delta value. The historical delta value represents the average difference between measured and declared values from previous measurements taken on similar material with the same measurement technology. If the measurement falls outside a limit of three times the historical delta value, the declaration is not verified. This paper uses measurement data from five years of IAEA courses to calculate a historical delta for five non-destructive assay methods: Gamma-ray Enrichment, Gamma-ray Plutonium Isotopics, Passive Neutron Coincidence Counting, Active Neutron Coincidence Counting and the Neutron Coincidence Collar. These historical deltas provide information as to the precision and accuracy of these measurement techniques under realistic conditions.

    Combining analysis of 3S (RS, GIS and GPS) and historical materials (historical records, ancient map and academic and literary writings) allows mapping of the Keriya Paleoriver of Southern Xinjiang, NW China. Keriya Paleoriver, one of the ancient Four Green Corridors which passes through the Taklimakan Desert from south to north in the Tarim Basin, recorded changes of the climate-environment in the ancient Silk Road of the region. According to the archaeological data, historical materials and paleoclimates information, its eco-environment and climate have had great changes since the 1.09Ma B.P., especially during the last 2,000 years, which has led to many famous ancient cities to be abandoned and the route of the ancient Silk Road to be moved southward. Using RS (optical and radar imagery), GIS (mapping and spatial analysis) and GPS (study area investigation), we mapped a major paleodrainage system of Keriya River, which have linked the Kunlun Mountains to the Tienshan Mountains through the Taklimakan Desert, possibly as far back as the early Pleistocene. This study illustrates the capability of the 3S and historical materials, in mapping the Keriya Paleoriver drainage networks and archaeological study on the ancient Silk Road.

    2011-10-01

    The lipid fractions of residues from historical pharmaceutical ointments were analysed by reversed-phase liquid chromatography coupled with atmospheric pressure chemical ionization and mass spectrometer detection. The residues were contained in a series of historical apothecary jars, dating from the eighteenth century and conserved at the "Aboca Museum" in Sansepolcro (Arezzo, Italy) and at the pharmacy of the "Real Cartuja de Valldemossa" in Palma de Majorca (Spain). The analytical protocol was set up using a comparative study based on the evaluation of triacylglycerol (TAG) compositions in raw natural lipid materials and in laboratory-reproduced ointments. These ointments were prepared following pharmaceutical recipes reported in historical treatises and used as reference materials. The reference materials were also subjected to stress treatments in order to evaluate the modification occurring in the TAG profiles as an effect of ageing. TAGs were successfully detected in the reproduced formulations even in mixtures of up to ten ingredients and after harsh degradative treatments, and also in real historical samples. No particular interferences were detected from other non-lipid ingredients of the formulations. The TAG compositions detected in the historical ointments indicated a predominant use of olive oil and pig adipose material as lipid ingredients. The detection of a high level of tristearine and myristyl-palmitoyl-stearyl glycerol in two of the samples suggested the presence of a fatty material of a different origin (maybe a ruminant). On the basis of the positional isomer ratio, sn-PPO/sn-POP, it was possible to hypothesize an exclusive use of pig fat in one sample. We also evaluated the application of principal component analysis of TAG profiles as an approach for the multivariate statistical comparison of the reference and historical ointments. PMID:21713420

  1. Some historical relationships between science and technology with implications for behavior analysis

    Moxley, Roy A.

    1989-01-01

    The relationship between science and technology is examined in terms of some implications for behavior analysis. Problems result when this relationship is seen as one in which science generally begets technology in a one-way, or hierarchical, relationship. These problems are not found when the relationship between science and technology is seen as two-way, or symmetrical, within a larger context of relationships. Some historical examples are presented. Collectively, these and other examples in the references weaken the case for a prevailing one-way, hierarchical relationship and strengthen the case for a two-way, symmetrical relationship. In addition to being more accurate historically, the symmetrical relationship is also more consistent with the principles of behavior analysis. PMID:22478016

    2011-08-01

    A new analytical approach based on high-performance liquid chromatography with diode array detector (HPLC-DAD) and multivariate data analysis was applied and assessed for analyzing the red dye extracted from cochineal insects, used in precious historical textiles. The most widely used method of analysis involves quantification of specific minor compounds (markers), using HPLC-DAD. However, variation in the cochineal markers concentration, use of aggressive dye extraction methods and poor resolution of HPLC chromatograms can compromise the identification of the precise insect species used in the textiles. In this study, a soft extraction method combined with a new dye recovery treatment was developed, capable of yielding HPLC chromatograms with good resolution, for the first time, for historical cochineal-dyed textiles. After principal components analysis (PCA) and mass spectrometry (MS), it was possible to identify the cochineal species used in these textiles, in contrast to the accepted method of analysis. In order to compare both methodologies, 7 cochineal species and 63 historical cochineal insect specimens were analyzed using the two approaches, and then compared with the results for 15 historical textiles in order to assess their applicability to real complex samples. The methodology developed here was shown to provide more accurate and consistent information than the traditional method. Almost all of the historical textiles were dyed with Porphyrophora sp. insects. These results emphasize the importance of adopting the proposed methodology for future research on cochineal (and related red dyes). Mild extraction methods and HPLC-DAD/MS(n) analysis yield distinctive profiles, which, in combination with a PCA reference database, are a powerful tool for identifying red insect dyes.

    The epileptologically informed in-depth analysis of auto- and heteroanamnestic historical sources supports the hypothesis that Hector Berlioz (1803-1869) might have suffered from a photosensitive idiopathic generalized epilepsy syndrome with absences, absence status, myoclonic seizures, and bilateral tonic-clonic seizures. The study outlines the possible influence of the composer's probable epilepsy on his literary and musical oeuvre, including the Symphonie fantastique en cinq parties. PMID:25684290

  4. In the shadow of a new smoke free policy: A discourse analysis of health care providers' engagement in tobacco control in community mental health

    PubMed Central

    2010-01-01

    Background The prevalence of tobacco use among individuals with mental illness remains a serious public health concern. Tobacco control has received little attention in community mental health despite the fact that many individuals with mental illness are heavy smokers and experience undue tobacco-related health consequences. Methods This qualitative study used methods of discourse analysis to examine the perceptions of health care providers, both professionals and paraprofessionals, in relation to their roles in tobacco control in the community mental health system. Tobacco control is best conceptualised as a suite of policies and practices directed at supporting smoke free premises, smoking cessation counselling and limiting access to tobacco products. The study took place following the establishment of a new policy that restricted tobacco smoking inside all mental health facilities and on their grounds. Ninety one health care providers participated in open-ended interviews in which they described their role in tobacco control. The interview data were analyzed discursively by asking questions such as: what assumptions underlie what is being said about tobacco? Results Five separate yet overlapping discursive frames were identified in which providers described their roles. Managing a smoke free environment emphasised the need to police and monitor the smoke free environment. Tobacco is therapeutic was a discourse that underscored the putative value of smoking for clients. Tobacco use is an individual choice located the decision to smoke with individual clients thereby negating a role in tobacco control for providers. It's someone else's role was a discourse that placed responsibility for tobacco control with others. Finally, the discourse of tobacco control as health promotion located tobacco control in a range of activities that are used to support the health of clients. Conclusions This study provides insights into the complex factors that shape tobacco control practices in the mental health field and reinforces the need to see practice change as a matter that extends beyond the individual. The study findings highlight discourses structured by power and powerlessness in environments in which health care providers are both imposing and resisting the smoke free policy. PMID:20667105

  6. The climatic effect of explosive volcanic activity: Analysis of the historical data

    1982-01-01

    By using the most complete available records of direct beam radiation and volcanic eruptions, an historical analysis of the role of the latter in modulating the former was made. A very simple fallout and dispersion model was applied to the historical chronology of explosive eruptions. The resulting time series explains about 77 percent of the radiation variance, as well as suggests that tropical and subpolar eruptions are more important than mid-latitude eruptions in their impact on the stratospheric aerosol optical depth. The simpler climatic models indicate that past hemispheric temperature can be stimulated very well with volcanic and CO2 inputs and suggest that climate forecasting will also require volcano forecasting. There is some evidence that this is possible some years in advance.

  7. Meteorological analysis and historical perspective of the 1999--2005 Canadian Prairie drought

    NASA Astrophysics Data System (ADS)

    Hryciw, Lisa

    Drought is a complex natural hazard which is endemic to the Canadian Prairies. The 1999--2005 Canadian Prairie drought, which had great socio-economic impacts, was meteorologically unique in that it did not conform to traditional persistent ridging paradigms normally associated with Prairie drought. The purpose of this study is to diagnose the unique synoptic-scale mechanisms that lead to the subsidence in this drought. Using 30-day running means of percent of normal precipitation from station data, we identify key severe dry periods in 1999--2005. Analysis of the mean fields from reanalysis data shows that these dry events are associated with combinations of larger scale subsidence mechanisms of anticyclonic vorticity advection and cold air advection, along with the smaller scale subsidence mechanism of downslope flow. A brief historical perspective shows that the drought was centred in 2001--2002 and was not as severe as historical droughts, suggesting the increased vulnerability of society.

    Historical records are an important source of information on extreme and rare floods and fundamental to establish a reliable flood return frequency. The use of long historical records for flood frequency analysis brings in the question of flood stationarity, since climatic and land-use conditions can affect the relevance of past flooding as a predictor of future flooding. In this paper, a detailed 400 yr flood record from the Tagus River in Aranjuez (central Spain) was analysed under stationary and non-stationary flood frequency approaches, to assess their contribution within hazard studies. Historical flood records in Aranjuez were obtained from documents (Proceedings of the City Council, diaries, chronicles, memoirs, etc.), epigraphic marks, and indirect historical sources and reports. The water levels associated with different floods (derived from descriptions or epigraphic marks) were computed into discharge values using a one-dimensional hydraulic model. Secular variations in flood magnitude and frequency, found to respond to climate and environmental drivers, showed a good correlation between high values of historical flood discharges and a negative mode of the North Atlantic Oscillation (NAO) index. Over the systematic gauge record (1913-2008), an abrupt change on flood magnitude was produced in 1957 due to constructions of three major reservoirs in the Tagus headwaters (Bolarque, Entrepeñas and Buendia) controlling 80% of the watershed surface draining to Aranjuez. Two different models were used for the flood frequency analysis: (a) a stationary model estimating statistical distributions incorporating imprecise and categorical data based on maximum likelihood estimators, and (b) a time-varying model based on "generalized additive models for location, scale and shape" (GAMLSS) modelling, which incorporates external covariates related to climate variability (NAO index) and catchment hydrology factors (in this paper a reservoir index; RI). Flood frequency analysis using documentary data (plus gauged records) improved the estimates of the probabilities of rare floods (return intervals of 100 yr and higher). Under non-stationary modelling flood occurrence associated with an exceedance probability of 0.01 (i.e. return period of 100 yr) has changed over the last 500 yr due to decadal and multi-decadal variability of the NAO. Yet, frequency analysis under stationary models was successful in providing an average discharge around which value flood quantiles estimated by non-stationary models fluctuate through time.

  10. A Historical Analysis of the Relationship Between Rice Production and PDSI Values in Sri Lanka

    2011-12-01

    As world population grows, there are ever increasing demands being placed on the food production systems throughout the world. Climate change is complicating these stressors even further through more frequent severe weather events. In the developing world, where there are fewer resources to mitigate the effects of climate change, the combination of these two factors can have drastic consequences. In Sri Lanka, farmers in major rice production areas of the country are already struggling to produce enough rice, a staple food of the local diet, and a severe wet or dry spell could be ruinous. Faced with a changing climate and a growing demand for rice, it is important to be able to anticipate how climatic changes will affect rice production. By examining how extreme wet and dry spells have historically affected rice production, decision makers may be better able to predict and prepare for potential food shortages. We conducted an analysis of historic temperature, precipitation, and rice production statistics in order to determine the effects of extreme wet and dry spells on rice production. We also created a timeline of major developments in Sri Lankan agriculture in order to compare effects on rice production due to changes in agricultural practices with meteorological changes. Historical temperature and precipitation data were used to calculate the Palmer Drought Severity Index (PDSI) for a number of stations distributed throughout the Mahaweli river basin. The basin, the largest in the country, contains three different climatic regions - dry, intermediate, and wet - that all receive different amounts of annual precipitation. The PDSI values were used to quantify drought and wetness during the Yala (April-September) and Maha (October-March) growing seasons. Analysis of historical PDSI values, agricultural advances, and rice production statistics shows great promise for anticipating and mitigating future food shortages.

  12. Problems and Cautions With Sequence Mismatch Analysis and Bayesian Skyline Plots to Infer Historical Demography.

    PubMed

    Grant, William Stewart

    2015-01-01

    Sequence mismatch analysis (MMA) and Bayesian skyline plots (BSP) are commonly used to reconstruct historical demography. A survey of 173 research articles (2009-2014), which included estimates of historical population sizes from mtDNA or cpDNA, shows a widespread genetic signature of demographic or spatial population expansion in species of all major taxonomic groups. Associating these expansions with climatic events can provide insights into the origins of lineage diversity, range expansions (or contractions), and speciation. However, several variables can introduce error into reconstructions of demographic history, including levels of sequence polymorphism, sampling scheme, sample size, natural selection, and estimates of mutation rate. Most researchers use substitution rates estimated from divergences in phylogenetic trees dated with fossils, or geological events. Recent studies show that molecular clocks calibrated with phylogenetic divergences can overestimate the timings of population-level events by an order of magnitude. Overestimates disconnect historical population reconstructions from climatic history and confound our understanding of the factors influencing genetic variability. If mismatch distributions and BSPs largely reflect demographic history, the widespread signature of population expansion in vertebrate, invertebrate, and plant populations appears to reflect responses to postglacial climate warming.

    This dissertation is a socio-historical analysis of the anti-nuclear weapons movement in the United States. This work conceptualizes social movements in advanced industrial societies by synthesizing certain aspects of social constructionism, resource mobilization, and new class theory. The research design is a socio-historical, comparative case study. Both qualitative and quantitative methods are employed for data analysis. Extensive content analysis of documents and interviews with key actors are supplemented with a critical analysis of a wide variety of primary and secondary data. All major antinuclear weapons protest, particularly the Atomic Scientists Movement of the 1940s, the Ban-the-Bomb Movement of the 1950s and 1960s, and the Freeze Movement of the 1980s, shared similar characteristics, and experienced similar problems. The findings are congruent with the theoretical synthesis. Antinuclear weapons protest is best understood as a new class phenomenon, in which intellectuals have mobilized resources to challenge the ruling elite. Yet, though the protest has succeeded in challenging the legitimacy of the ruling apparatus, successes of the movement have been mostly symbolic.

    The paper addresses two complex case studies of modal and structural identification of monuments in Portugal: the Clock Tower of Mogadouro and the Church of Jerónimos Monastery, in Lisbon. These are being monitored by University of Minho with vibration, temperature and relative air humidity sensors. Operational modal analysis is being used to estimate the modal parameters, followed by statistical analysis to evaluate the environmental effects on the dynamic response. The aim is to explore damage assessment in masonry structures at an early stage by vibration signatures, as a part of a health monitoring process that helps in the preservation of historical constructions. The paper presents the necessary preliminary dynamic analysis steps before the monitoring task, which includes installation of the monitoring system, system identification and subsequent FE model updating analysis, automatic modal identification and investigation of the influence of the environment on the identified modal parameters.

  15. Politics and the struggle to define: a discourse analysis of the framing strategies of competing actors in a 'new' participatory forum.

    1997-09-01

    On account of the current wave of environmental consciousness, the state is adapting to the phenomena of systems of negotiations outside of the traditional institutional framework on environmental issues in an attempt to preserve cultural support. However recent experiments in discursive democracy have proven to be a modality for the transmission of productivist culture and for the reassertion of corporatist tendencies. This interpretation finds support here primarily through a discourse analysis based on a three-dimensional framework. The analysis begins by examining the structure of discursive formations of various participating actors at the Irish National Recycling Conference in 1993, and explores the ways in which actors struggled at the symbolic level to define the rules constitutive of this space of play. It argues from the perspective of discourse as social practice and justifies this approach by assessing the degree of synchronization between collective actors' systems of discursivity and the socially structured institutional sites within which they are embedded. Finally, by examining the position of this field vis-à-vis the field of political power, this research will show how broader relations of domination and traditional power asymmetries came to be reasserted in a 'new' participatory arrangement.

  16. Envisioning the Third Sector's Welfare Role: Critical Discourse Analysis of ‘Post-Devolution’ Public Policy in the UK 1998–2012

    2014-01-01

    Welfare state theory has struggled to come to terms with the role of the third sector. It has often categorized welfare states in terms of the pattern of interplay between state social policies and the structure of the labour market. Moreover, it has frequently offered an exclusive focus on state policy – thereby failing to substantially recognize the role of the formally organized third sector. This study offers a corrective view. Against the backdrop of the international shift to multi-level governance, it analyses the policy discourse of third sector involvement in welfare governance following devolution in the UK. It reveals the changing and contrasting ways in which post-devolution territorial politics envisions the sector's role as a welfare provider. The mixed methods analysis compares policy framing and the structural narratives associated with the development of the third sector across the four constituent polities of the UK since 1998. The findings reveal how devolution has introduced a new spatial policy dynamic. Whilst there are elements of continuity between polities – such as the increasing salience of the third sector in welfare provision – policy narratives also provide evidence of the territorialization of third sector policy. From a methodological standpoint, this underlines the distinctive and complementary role discourse-based analysis can play in understanding contemporary patterns and processes shaping welfare governance.

  17. Adolescent pregnancies and girls' sexual and reproductive rights in the amazon basin of Ecuador: an analysis of providers' and policy makers' discourses

    PubMed Central

    2010-01-01

    Background Adolescent pregnancies are a common phenomenon that can have both positive and negative consequences. The rights framework allows us to explore adolescent pregnancies not just as isolated events, but in relation to girls' sexual and reproductive freedom and their entitlement to a system of health protection that includes both health services and the so called social determinants of health. The aim of this study was to explore policy makers' and service providers' discourses concerning adolescent pregnancies, and discuss the consequences that those discourses have for the exercise of girls' sexual and reproductive rights' in the province of Orellana, located in the amazon basin of Ecuador. Methods We held six focus-group discussions and eleven in-depth interviews with 41 Orellana's service providers and policy makers. Interviews were transcribed and analyzed using discourse analysis, specifically looking for interpretative repertoires. Results Four interpretative repertoires emerged from the interviews. The first repertoire identified was "sex is not for fun" and reflected a moralistic construction of girls' sexual and reproductive health that emphasized abstinence, and sent contradictory messages regarding contraceptive use. The second repertoire -"gendered sexuality and parenthood"-constructed women as sexually uninterested and responsible mothers, while men were constructed as sexually driven and unreliable. The third repertoire was "professionalizing adolescent pregnancies" and lead to patronizing attitudes towards adolescents and disregard of the importance of non-medical expertise. The final repertoire -"idealization of traditional family"-constructed family as the proper space for the raising of adolescents while at the same time acknowledging that sexual abuse and violence within families was common. Conclusions Providers' and policy makers' repertoires determined the areas that the array of sexual and reproductive health services should include, leaving out the ones more prone to cause conflict and opposition, such as gender equality, abortion provision and welfare services for pregnant adolescents. Moralistic attitudes and sexism were present - even if divergences were also found-, limiting services' capability to promote girls' sexual and reproductive health and rights. PMID:20525405

    The films Mädchen in Uniform (Leontine Sagan, 1931, Germany; Géza von Radványi, 1958, Germany) both tell the story of a schoolgirl falling in love with her teacher at a Prussian boarding school. Whereas the 1931 version is regarded as a lesbian classic in queer (German) cinema, the 1958 remake, however, is not even considered part of the lesbian genre. The following analysis examines both films within their historical context to answer the question what makes Mädchen in Uniform (1931) a lesbian film and why the remake did not measure up to its original's significance.

    2011-04-01

    The proposed multilevel framework of discourse comprehension includes the surface code, the textbase, the situation model, the genre and rhetorical structure, and the pragmatic communication level. We describe these five levels when comprehension succeeds and also when there are communication misalignments and comprehension breakdowns. A computer tool has been developed, called Coh-Metrix, that scales discourse (oral or print) on dozens of measures associated with the first four discourse levels. The measurement of these levels with an automated tool helps researchers track and better understand multilevel discourse comprehension. Two sets of analyses illustrate the utility of Coh-Metrix in discourse theory and educational practice. First, Coh-Metrix was used to measure the cohesion of the text base and situation model, as well as potential extraneous variables, in a sample of published studies that manipulated text cohesion. This analysis helped us better understand what was precisely manipulated in these studies and the implications for discourse comprehension mechanisms. Second, Coh-Metrix analyses are reported for samples of narrative and science texts in order to advance the argument that traditional text difficulty measures are limited because they fail to accommodate most of the levels of the multilevel discourse comprehension framework.

  3. Application of LC-MS to the analysis of dyes in objects of historical interest

    NASA Astrophysics Data System (ADS)

    Zhang, Xian; Laursen, Richard

    2009-07-01

    High-performance liquid chromatography (HPLC) with photodiode array and mass spectrometric detection permits dyes extracted from objects of historical interest or from natural plant or animal dyestuffs to be characterized on the basis of three orthogonal properties: HPLC retention time, UV-visible spectrum and molecular mass. In the present study, we have focused primarily on yellow dyes, the bulk of which are flavonoid glycosides that would be almost impossible to characterize without mass spectrometric detection. Also critical for this analysis is a method for mild extraction of the dyes from objects (e.g., textiles) without hydrolyzing the glycosidic linkages. This was accomplished using 5% formic acid in methanol, rather than the more traditional 6 M HCl. Mass spectroscopy, besides providing the molecular mass of the dye molecule, sometimes yields additional structural data based on fragmentation patterns. In addition, coeluting compounds can often be detected using extracted ion chromatography. The utility of mass spectrometry is illustrated by the analysis of historical specimens of silk that had been dyed yellow with flavonoid glycosides from Sophora japonica (pagoda tree) and curcumins from Curcuma longa (turmeric). In addition, we have used these techniques to identify the dye type, and sometimes the specific dyestuff, in a variety of objects, including a yellow varnish from a 19th century Tibetan altar and a 3000-year-old wool mortuary textiles, from Xinjiang, China. We are using HPLC with diode array and mass spectrometric detection to create a library of analyzed dyestuffs (>200 so far; mostly plants) to serve as references for identification of dyes in objects of historical interest.

  4. Health risks, social relations and class: an analysis of occupational health discourse in Finnish newspaper and women's magazine articles 1961-2008.

    In this article we examine the treatment of psychosocial risks in public occupational health discourse in Finnish newspaper and magazine articles between the 1960s and 2000s, using discourse analysis. Building on class theories, our aim is to investigate how class expectations have been linked with the redefinition of occupational health risks during this period. Our results suggest that as social relations at the workplace became problematised in the occupational health discussions after the 1970s, the image of the hierarchical and naturally conflictual organisation was replaced by idealised middle-class notions of smoothly functioning, harmonious organisations that offered rewarding work experiences. However, this same period since the late 1970s has also been characterised by increasing economic competition and neoliberal market ideology. We conclude that the concern about work-related psychosocial risks and health problems expressed in Finnish newspaper and magazine articles during the last three decades has been shaped in many respects by a collision between the dominant middle-class expectations of harmony and equality and the neoliberal production of competition and inequality.

  5. Age transcended: a semiotic and rhetorical analysis of the discourse of agelessness in North American anti-aging skin care advertisements.

    Ellison, Kirsten L

    2014-04-01

    Drawing from a collection of over 160 North American print advertisements for anti-aging skin care products from January to December of 2009, this paper examines the discourse of agelessness, a vision of esthetic perfection and optimal health that is continually referred to by gerontologists, cultural theorists, and scientific researchers as a state of being to which humankind can aspire. Employing critical discourse analysis through the use of semiotics and visual rhetoric, this paper explores the means through which anti-aging skin care advertisements present to their viewers a particular object of desire, looking, more specifically, at how agelessness is presented as a way out and ultimate transcendence of age. Through the analytical tools of semiotics and visual rhetoric, four visions of agelessness are identified and explored in this paper: Agelessness as Scientific Purity, Agelessness as Genetic Impulse, Agelessness as Nature's Essence, and Agelessness as Myth. Whether found in the heights of scientific purity, the inner core of our genetic impulse, the depths of nature's essence, or whether agelessness itself has reached its own, untouchable, mythic status, the advertisements in this study represent one of the most pervasive vehicles through which our current vision(s) of ageless perfection are reflected, reinforced, and suspended in a drop of cream.

  7. Men and talk about legal abortion in South Africa: equality, support and rights discourses undermining reproductive 'choice'.

    Macleod, Catriona Ida; Hansjee, Jateen

    2013-01-01

    Discursive constructions of abortion are embedded in the social and gendered power relations of a particular socio-historical space. As part of research on public discourses concerning abortion in South Africa where there has been a radical liberalisation of abortion legislation, we collected data from male group discussions about a vignette concerning abortion, and newspaper articles written by men about abortion. Our analysis revealed how discourses of equality, support and rights may be used by men to subtly undermine women's reproductive right to 'choose' an abortion. Within an Equal Partnership discourse, abortion, paired with the assumption of foetal personhood, was equated with violating an equal heterosexual partnership and a man's patriarchal duty to protect a child. A New Man discourse, which positions men as supportive of women, was paired with the assumption of men as rational and women as irrational in decision-making, to allow for the possibility of men dissuading women from terminating a pregnancy. A Rights discourse was invoked to suggest that abortion violates men's paternal rights. PMID:23768420

    2015-01-01

    ABSTRACT Background: Analyzing the historical and social path of an occupation using the sociology of professions and the perspective of scientific knowledge promotes an understanding of the origin of physical therapy in Brazil and of discussions of the profession in its contemporary context. Objective: The aim of this paper was to discuss the professionalization process of physical therapy in São Paulo. The authors tried to analyze bath therapy, massage therapy, and physical therapy as occupations involving distinct expertise and as part of the group of occupations that evolved into the profession of physiotherapy in the first half of the twentieth century. Method: The analysis undertaken was a qualitative study based on an analysis of historical documents. Eighty-six professional records from the Service of Inspection of Professional Practice in the state of São Paulo and healthcare legislation from the 1930s and 1940s were analyzed. Results: The distinction between physical therapy practitioner and profession of physiotherapy can be seen by examining registration requirements for rank-and-file nurses with expertise in interactions; this distinction suggests the emergence of specialized expertise that was clearly a part of neither medicine nor nursing and contributed to expertise in physical therapy since the 1950s. Conclusion: The regulation of physiotherapy practices, the recognition of expertise, the accreditation of practical nurses by the State, and the institutionalization of a course for physical therapy practitioners in 1951 are key elements of the professionalization process for the physical therapy profession in Brazil.

    Drought is a complex natural hazard that is endemic to the Canadian Prairies. The 1999-2005 Canadian Prairie drought, which had great socio-economic impacts, was meteorologically unique in that it did not conform to traditional persistent ridging paradigms normally associated with Prairie drought. The purpose of this study is to diagnose the unique synoptic-scale mechanisms that led to the subsidence in this drought. Using 30-day running means of percent of normal precipitation from 33 meteorological stations in the affected Canadian Prairie region, we identify 10 particularly key severe 30-day dry periods during the 1999-2005 period. Analysis of the mean fields from global and regional reanalysis data show that these dry events are associated with combinations of larger scale subsidence mechanisms of anticyclonic vorticity advection and cold air advection, along with the smaller scale subsidence mechanism of downslope flow. A detailed analysis of each 30-day period, partitioned by the dominant subsidence mechanism, reveals only a weak association with teleconnection indices as the PNA, or with ENSO. A brief historical perspective shows that the drought was centered in 2001-2002 and was not as severe as historical droughts, suggesting an increasing vulnerability of society.

  10. Social aspects of classroom learning: Results of a discourse analysis in an inquiry-oriented physical chemistry class

    NASA Astrophysics Data System (ADS)

    Becker, Nicole M.

    Engaging students in classroom discourse offers opportunities for students to participate in the construction of joint understandings, to negotiate relationships between different types of evidence, and to practice making evidence-based claims about science content. However, close attention to social aspects of learning is critical to creating inquiry-oriented classroom environments in which students learn with understanding. This study examined the social influences that contribute to classroom learning in an inquiry-oriented undergraduate physical chemistry class using the Process Oriented Guided Inquiry Learning (POGIL) approach. A qualitative approach to analyzing classroom discourse derived from Toulmin's (1968) model of argumentation was used to document patterns in classroom reasoning that reflect normative aspects of social interaction. Adapting the constructs of social and sociomathematical norms from the work of Yackel and Cobb (1996), I describe social aspects of the classroom environment by discussing normative aspects of social interaction (social norms) and discipline-specific criteria related to reasoning and justification in chemistry contexts, referred to here as sociochemical norms. This work discusses four social norms and two sociochemical norms that were documented over a five-week period of observation in Dr. Black's POGIL physical chemistry class. In small group activities, the socially established expectations that students explain reasoning, negotiate understandings of terminology and symbolic representations, and arrive at a consensus on critical thinking questions shaped small group interactions and reasoning. In whole class discussion, there was an expectation that students share reasoning with the class, and that the instructor provide feedback on student reasoning in ways that extended student contributions and elaborated relationships between macroscopic, particulate, and symbolic-level ideas. The ways in which the class constructed evidence-based claims about chemistry content reflected the influence of sociochemical norms that were enacted through classroom discourse. Two sociochemical norms were documented in both whole class and small group activities: first, the class used particulate-level evidence to make claims about chemical and physical properties; second, particular ways of using mathematical reasoning to justify claims about thermodynamics content became normative for the class. These similarities and differences between social and sociochemical norms in small group and whole class discussion highlight ways in which instructor facilitation can support productive interactions in classroom activities.

    Farrow, Tony L; O'Brien, Anthony J

    2005-09-01

    In late 2001 Canterbury, New Zealand mental health nurses undertook a variety of strike actions after stalled industrial negotiations with the local district health board. One response to these actions was the temporary reduction of many of the regions metal health services. Unsurprisingly, the print media responded by publicizing the crisis in mental health services on an almost daily basis. This paper reports on subsequent research into these print media representations of the industrial disputes, identifying themes of juxtaposed but largely deprecatory images of both mental health nursing and of consumers of services. Some professional nursing voices were given print space during the strike; however, these were largely incorporated into existing discourses rather than offering a nursing viewpoint on the strike. We, therefore, conclude by suggesting organizational efforts to focus on ways of ensuring that mental health nurses are seen as a legitimate authority by the media. PMID:16181156

  14. Science Pedagogy as a Category of Historical Analysis: Past, Present, and Future

    Olesko, Kathryn M.

    2006-11-01

    Historical studies of science pedagogy have flourished in recent years. This essay offers an assessment of the literature on science pedagogy from the 1930s to the present. It argues that rather than focusing on the work of Thomas Kuhn and Michel Foucault, historians of science pedagogy could with profit turn to the work of Ludwik Fleck. Fleck offers three categories of historical analysis - experience, sensation, and cognition - that are embedded in science pedagogy. He furthermore argues unequivocally for the central importance of considering the cultural context of science pedagogy. Fleck’s interpretation of the role of publishing in science is used in the final section of this essay to assess scientific publishing and textbook culture, topics that are the principal concern of the articles in this volume. Among the novelties of the articles in this volume on textbooks are (1) the connections they draw between textbooks and social structure; (2) the relationships they suggest between textbooks and the public sphere; and (3) their identification of the eighteenth century as the crucial transformative century in textbook production.

    Komduur, Rixt; Te Molder, Hedwig

    2014-11-01

    This study examines whether the assumptions embedded in nutrigenomics, especially the alleged relation between information about personal health risks and healthy behaviour, match how people account for the relation between food, health and genes in everyday life. We draw on discourse analysis to study accounts of overweight in six group interviews with people who are and who are not overweight. The results show potentially contradictory normative orientations towards behavioural explanations of (over)weight. Overt gene accounts are interactionally problematic (in contrast to more indirect accounts such as 'build'), indicating that participants treat 'behaviour' as the normatively appropriate explanation for overweight. At the same time, however, healthy behaviour is an accountable matter, i.e. it is dealt with in interaction as behaviour that is not self-evidently right but requires an explanation. It is discussed how bringing these interactional concerns to the surface is essential for understanding future users' response to nutrigenomics and emergent technologies more in general.

    2009-08-01

    Raman, infrared and XRD analysis have been applied to the examination of deterioration on historical monuments (Morelia, Mexico). Forty-three samples pyroclastic volcanic rocks (ignimbrites) have been studied, all originating from two ex-convents San Francisco and San Agustin, which were the first architectonic complexes in the city of Morelia. Several new mineral neoformation such as sulfates, carbonates, halides, and phosphates were identified in these samples with spectrometric and XRD technique. The observed Raman and infrared spectra are reported and some mineral compound assignments in unaltered and deteriorated volcanic rocks have been made. This survey is the first Raman and infrared spectrometric examination of the environmental mineralogy in Mexico under conditions of urban weathering that are characterized mainly by one secondary alteration formations of low scale.

  1. Historical Epidemics Cartography Generated by Spatial Analysis: Mapping the Heterogeneity of Three Medieval "Plagues" in Dijon

    2015-01-01

    Objectives This work was designed to adapt Geographical Information System-based spatial analysis to the study of historical epidemics. We mapped "plague" deaths during three epidemics of the early 15th century, analyzed spatial distributions by applying the Kulldorff's method, and determined their relationships with the distribution of socio-professional categories in the city of Dijon. Materials and Methods Our study was based on a database including 50 annual tax registers (established from 1376 to 1447) indicating deaths and survivors among the heads of households, their home location, tax level and profession. The households of the deceased and survivors during 6 years with excess mortality were individually located on a georeferenced medieval map, established by taking advantage of the preserved geography of the historical center of Dijon. We searched for clusters of heads of households characterized by shared tax levels (high-tax payers, the upper decile; low-tax payers, the half charged at the minimum level) or professional activities and for clusters of differential mortality. Results High-tax payers were preferentially in the northern intramural part, as well as most wealthy or specialized professionals, whereas low-tax payers were preferentially in the southern part. During two epidemics, in 1400–1401 and 1428, areas of higher mortality were found in the northern part whereas areas of lower mortality were in the southern one. A high concentration of housing and the proximity to food stocks were common features of the most affected areas, creating suitable conditions for rats to pullulate. A third epidemic, lasting from 1438 to 1440 had a different and evolving geography: cases were initially concentrated around the southern gate, at the confluence of three rivers, they were then diffuse, and ended with residual foci of deaths in the northern suburb. Conclusion Using a selected historical source, we designed an approach allowing spatial analysis of urban medieval epidemics. Our results fit with the view that the 1400–1401 epidemic was a Black Death recurrence. They suggest that this was also the case in 1428, whereas in 1438–1440 a different, possibly waterborne, disease was involved. PMID:26625117

    2013-06-01

    The original article by Kamberelis and Wehunt (2012) discusses an interesting and important research subject in science education as it focus on classroom interactions and the characteristics of the discourse production of interlocutors. The authors start from the premise that discourse heterogeneity is constitutive of social activities, which is supported by others like Mikhail Bakhtin (Speech genres and other late essays. University of Texas Press, Austin, 1981) and Erving Goffman (Frame analysis: an essay on the organization of experience. Harper and Row, London, 1974). They also present the definitions of three key elements that organize hybrid discourse: (a) lamination of multiple cultural frames, (b) shifting relations between people and their discourse, and (c) shifting power relations between people. Finally, the authors analyze how these three elements organize students' science discourse in the classroom and how it contributes to the creation of a micro-community of practice capable of helping the emergence of a disciplinary knowledge that is legitimized by and strengthens the identity of the group. In the present commentary, I discuss how Michael Foucault's (1970) concept of discursive procedure may help us to analyze the (often neglected) teacher's role in the development of hybrid discourse practices.

  3. Object-oriented analysis of multi-temporal panchromatic images for creation of historical landslide inventories

    Object-oriented analysis (OOA) has been demonstrated to produce more accurate results than pixel-based image processing. Studies carried out by previous researchers have shown how landslide inventories can be prepared from multispectral satellite images using OOA. However, panchromatic images are frequently the only data available after a landslide event. Furthermore, preparation of historical inventories relies on the analysis of satellite images and aerial photographs acquired over past few decades that are also mostly only available in black and white. In such cases the methodology developed using multispectral data cannot be used directly due to limited spectral information, in particular in near-infrared bands. In this paper we present a new methodology that addresses some of these issues. Using high resolution panchromatic images from Cartosat-1 (2.5 m) and IRS-1D (5.8 m), and a 10 m gridded DTM extracted from Cartosat-1, we developed a new approach which uses change detection techniques and a global contextual criteria in an object-based environment to detect and classify landslides into five different types. Continuous time series images from 1998 to 2006 were used to prepare annual landslide inventories in a highly rugged Himalayan terrain. The maximum and minimum detection percentages achieved for all landslides are 96.7% and 71.5%, respectively, with corresponding quality percentages of 88.1% and 55.3%, respectively. However, the lack of spectral information proved to be a hurdle resulting in a high branching factor that indicates that further work is required to eliminate false positives. Nevertheless, the method was able to create much needed historical landslide inventories, which are critical for landslide hazard and risk assessment studies.

  7. An Alternative Analysis of the Discourse by Descartes, Kant and Hegel in terms of the Ethical Structure of the Kanun.

    PubMed

    Yamamoto, Kazuhiko

    2015-06-01

    The ethical structure of the Albanian customary code, the Kanun, is deemed to represent the ethical value system of a society without state power. In spite of the appearance of civilizations and the resultant advent of an incipient state power, humans seemed to have known only the ethical value system of a society without state power until Gotama, Socrates, Plato and Jesus proposed new religious and philosophical doctrines. The basic trait of these religious and philosophical doctrines, which try to antagonize the ethical value system of a society without state power by eliminating the emotional aspect of humanity from the ethical value system, has been inherited by western philosophers such as Descartes, Kant and Hegel. The discourses by Descartes, Kant and Hegel were reviewed while paying attention to how they dealt with the sensuous and emotional aspects of humanity. The metaphysical implications of the ethical structure of the Kanun surfaced through the critical reviewing of their philosophy, and a hypothesis concerning its origin was presented. PMID:26753448

  8. Informational database methodology for urban risk analysis.Case study: the historic centre of Bucharest

    2009-04-01

    The urban environment often deals with issues concerning the deterioration of the constructed space and the quality of the environmental factors, in general terms meaning an unsatisfactory quality of life. Taking into account the complexity of the urban environment and the strong human impact, this ambience can be considered the ideal place for a varied range of risks to appear, being favoured by the external interventions and the dynamics of the internal changes that occur in the urban system, often unexpectedly. In this context, historic centre areas are even more vulnerable because of the age of the buildings and their socio-cultural value. The present study focuses on the development of a rapid assessment system of urban risks, putting emphasis on earthquakes. The importance of the study is shown by the high vulnerability that defines urban settlements, which can be considered socio-ecological systems characterized by a maximum risk level. In general, cities are highly susceptible areas because of their compactness and elevated degree of land occupancy, the Bucharest municipality being no exception. The street and sewerage networks disorganized the natural system resulted from the evolution of the lake-river system in Superior Pleistocene-Holocene and the intense construction activity represents a pressure that hasn't been measured and that is in need for a methodological interdisciplinary approach. In particular, the specific of Bucharest is given by the seismic risk based on an explosive urban evolution and the advanced state of degradation of the buildings. In this context, the Lipscani sector from the historic centre of the capital city is a maximum seismic vulnerability area, this being the result of its location in the Dâmbovita River meadow, on the brow and 80 m terrace, but more precisely because of the degradation of the buildings that cumulated the effects of the repeated earthquakes. The historic centre of Bucharest has not only a cultural function, but is also a very populated area, this being factors that favour a high susceptibility level. In addition, the majority of the buildings are included in the first and second categories of seismic risk, being built between 1875 and 1940, the age of the buildings establishing an increased vulnerability to natural hazards. The methodology was developed through the contribution of three partner universities from Bucharest: the University of Bucharest, the Academy for Economic Studies and the Technical University of Constructions. The method suggested was based on the analysis and processing of digital and statistical spatial information resulted from 1:500 topographical plans, satellite pictures, archives and historical maps used for the identification of the age of the buildings. Also, an important stage was represented by the field investigations that resulted with the data used in the assessment of the buildings: year of construction, location and vicinity, height, number of floors, state and function of the building, equipment and construction type. The information collected from the field together with the data resulted from the digitization of the ortophotoplans were inserted in ArcGIS in order to compile the database. Furthermore, the team from the Cybernetics Faculty developed a special software package in Visual Studio and SQL server in order to insert the sheets in GIS so that they could be statistically processed. The final product of the study is a program that includes as main functions editing, the analysis based on selected factors (individual or group) and viewing of building information in the shape of maps or 3D visualization. The strengths of the informational system resulted are given by the extended range of applicability, the short processing period, accessibility, capacity of support for a large amount of information and, thus, standing out as an adequate instrument to fit the needs of a susceptible population.

  9. Using Simple Statistical Analysis of Historical Data to Understand Wind Ramp Events

    SciTech Connect

    Kamath, C

    2010-01-29

    As renewable resources start providing an increasingly larger percentage of our energy needs, we need to improve our understanding of these intermittent resources so we can manage them better. In the case of wind resources, large unscheduled changes in the energy output, called ramp events, make it challenging to keep the load and the generation balanced. In this report, we show that simple statistical analysis of the historical data on wind energy generation can provide insights into these ramp events. In particular, this analysis can help answer questions such as the time period during the day when these events are likely to occur, the relative severity of positive and negative ramps, and the frequency of their occurrence. As there are several ways in which ramp events can be defined and counted, we also conduct a detailed study comparing different options. Our results indicate that the statistics are relatively insensitive to these choices, but depend on utility-specific factors, such as the magnitude of the ramp and the time interval over which this change occurs. These factors reflect the challenges faced by schedulers and operators in keeping the load and generation balanced and can change over the years. We conduct our analysis using data from wind farms in the Tehachapi Pass region in Southern California and the Columbia Basin region in Northern Oregon; while the results for other regions are likely to be different, the report describes the benefits of conducting simple statistical analysis on wind generation data and the insights that can be gained through such analysis.

    2003-04-01

    Non systematic information gives in flood frequency analysis more reliability for estimated quantiles. This type of information has been collected at different places in Spain, during the European project SPHERE. Two case studies were analyzed, the Onyar river at Gerona city, in which historical information was available, and Llobregat river where we had palaeofloods records. Two types of distribution functions have been used: 1) Without upper limit, choosing TCEV and GEV models and 2) With upper limit, where three distributions functions recently published in literature have been used: the EV4, the four parameters Lognormal with Slade transformation and Gumbel with Eliasson transformation. This type of distribution function has been applied to the extreme frequency analysis of annual maximum daily precipitation by some authors, however all of them assume that the value of upper limit is previously known in order to improve the quantile estimates. In this work the PMF was estimated as one more parameter of the statistical model. The PMF confidence interval was computed using Montecarlo simulations. For two case studies, it was possible to improve the estimated quantiles and the PMF, and it was possible to identify the advantage of using non systematic information.

  11. Toward the modeling of land use change: A spatial analysis using remote sensing and historical data

    Honea, R. B.

    1976-01-01

    It was hypothesized that the chronological observation of land use change could be shown to follow a predictable pattern and these patterns could be correlated with other statistical data to develop transition probabilities suitable for modeling purposes. A literature review and preliminary research, however, indicated a totally stochastic approach was not practical for simulating land use change and thus a more deterministic approach was adopted. The approach used assumes the determinants of the land use conversion process are found in the market place, where land transactions among buyers and sellers occur. Only one side of the market transaction process is studied, however, namely, the purchaser's desires in securing an ideal or suitable site. The problem was to identify the ideal qualities, quantities or attributes desired in an industrial site (or housing development), and to formulate a general algorithmic statement capable of identifying potential development sites. Research procedures involved developing a list of variables previously noted in the literature to be related to site selection and streamlining the list to a set suitable for statistical testing. A sample of 157 industries which have located (or relocated) in the 16-county Knoxville metropolitan region since 1950 was selected for industrial location analysis. Using NASA color infrared photography and Tennessee Valley Authority historical aerial photography, data were collected on the spatial characteristics of each industrial location event. These data were then subjected to factor analysis to determine the interrelations of variables.

    Throughout the world there are hundreds of historic monuments and structures considered to be invaluable and irreplaceable. They are symbols of cultural identity and a means of educating people about history. Preservation of historic monuments and structures is therefore an important part of safeguarding these cultural heritage sites so that they retain their value for future generations.This report discusses a procedure for the investigation of seismic hazards in existing buildings and possible steps that can be taken to avoid damage caused by these hazards. The Augusta Airship Hangar located in Sicily, will be used as a case study however the topics addressed in this paper can be applied to other structures of historic value around the world.First state-of-the-art scanning procedures were used to create scale digital models that were imported into a structural analysis program. Within this program dynamic analyses were performed on the model based on actual ground motions taken close to the site. This data was used to determine the period and mode shapes of the structure. Then a nonlinear analysis, including a static pushover analysis, was implemented on a two-dimensional model of the structural frame. From this analysis the failure mechanisms of the structure were revealed with relation to an allowable roof displacement. The structural integrity of the structure was evaluated based on pre-defined performance goals. Finally multiple suggestions were made how the Augusta Airship Hangar might be repaired and strengthened so that this structure will not be destroyed should an earthquake occur.The results of our study show that historic structures, despite their age, can still be strong and ductile. Also there are a multitude of effective preservation and retrofit techniques that can be used to strengthen these historic structures, should an earthquake occur. Through this study, the Augusta Airship Hangar has proven to be not only a historic symbol for Sicily but also can be used as an example for the rehabilitation of other historic structures. The techniques and processes discussed in this paper can be applied to other historic reinforced concrete structures and can be expanded upon in future investigations.

  8. The expositive discourse as pedagogical discourse: studying recontextualization in the production of a science museum exhibition

    NASA Astrophysics Data System (ADS)

    McLaughlin, Cheryl A.

    2014-10-01

    In this paper I report on the sociological and educational particulars of The Biodiscovery Space exhibition of the Life Museum of the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil, using Basil Bernstein's framework of pedagogic discourse and recontextualization. Data for analysis was obtained from interviews with the exhibition developers, field observations of museum visitors and analysis of exhibition documents. Using the ideas of power, classification and framework, among others, I analyzed the recontextualization process of the production of expositive discourse. Thus, working with Bernstein's idea of classification, I explain the relationship between the discourses of the science of biology, history of science, museology, education, and communication in order to produce an expositive discourse. I also make explicit how agents of the Official Recontextualization Field of the Museum and the Pedagogic Recontextualization Field "....of the Museum determine partly the final expositive discourse of an exhibition". Using the idea of a pedagogic discourse framework, I discuss how the constraints imposed by objects and texts in exhibitions help to create a specific manner of visitor interaction with these elements, "even if they have some autonomy". Considerations about the audience and the intended process of acquisition are presented, when I discuss the control strategies of the exhibition. I propose that the Biodiscovery Space exhibit has a visible pedagogy. Finally, using the collected data I discuss the power tensions created in the production of expositive discourse showing how distributive, recontextualization and evaluation rules work in the context of exhibitions. The study of the dynamics in forming the expositive discourse using Bernstein's framework reveals the individuals and institutions, the selection criteria, the negotiations and the power relations involved. It has the potential to assist both educators and researchers in the museum education field, as well as designers to understand the teaching and learning processes that occur during a visit and to establish relevant criteria to evaluate quality to best produce exhibitions in science museums.

    Advances over the last fifteen years have made social network analysis (SNA) a powerful tool for the study of nonhuman primate social behavior. Although many SNA-based techniques have been only very recently adopted in primatological research, others have been commonly used by primatologists for decades. The roots of SNA also stem from some of the same conceptual frameworks as the majority of nonhuman primate behavioral research. The rapid development of SNA in recent years has led to questions within the primatological community of where and how SNA fits within this field. We aim to address these questions by providing an overview of the historical relationship between SNA and the study of nonhuman primates. We begin with a brief history of the development of SNA, followed by a detailed description of the network-based visualization techniques, analytical methods and conceptual frameworks which have been employed by primatologists since as early as the 1960s. We also introduce some of the latest advances to SNA, thereby demonstrating that this approach contains novel tools for study of nonhuman primate social behavior which may be used to shed light on questions that cannot be addressed fully using more conventional methods.

    Video based tracking is capable of analysing bridge vibrations that are characterised by large amplitudes and low frequencies. This paper presents the use of video images and associated image processing techniques to obtain the dynamic response of a pedestrian suspension bridge in Cork, Ireland. This historic structure is one of the four suspension bridges in Ireland and is notable for its dynamic nature. A video camera is mounted on the river-bank and the dynamic responses of the bridge have been measured from the video images. The dynamic response is assessed without the need of a reflector on the bridge and in the presence of various forms of luminous complexities in the video image scenes. Vertical deformations of the bridge were measured in this regard. The video image tracking for the measurement of dynamic responses of the bridge were based on correlating patches in time-lagged scenes in video images and utilisinga zero mean normalised cross correlation (ZNCC) metric. The bridge was excited by designed pedestrian movement and by individual cyclists traversing the bridge. The time series data of dynamic displacement responses of the bridge were analysedto obtain the frequency domain response. Frequencies obtained from video analysis were checked against accelerometer data from the bridge obtained while carrying out the same set of experiments used for video image based recognition.

  14. Use of longitudinal analysis of peripheral blood counts to validate historical reconstructions of benzene exposure.

    Kipen, H M; Cody, R P; Goldstein, B D

    1989-01-01

    We studied over 17,000 peripheral blood counts, accumulated during hematologic surveillance from 1940 through 1975, from a cohort of 459 benzene-exposed workers. Linear regressions demonstrated significant decreases in white and red cell counts, as well as hemoglobin, for workers exposed during the 1940s, without persistent trends over the ensuing 25 years. Strongly positive correlations were observed between these blood count fluctuations and fluctuations in retrospective estimates of benzene exposures for these workers in the earlier period of surveillance (mean estimated exposure 1940 to 1948, 75 ppm), but not for later years, (mean estimated exposure 1948 to 1975, 15 to 20 ppm). These data suggest substantial limitations of hematologic examination of populations to detect abnormalities in populations currently exposed to benzene. The analysis also demonstrates a novel approach to the biological validation of exposure estimates based upon limited industrial hygiene and historical record data. The application of biologic monitoring data may be useful for assisting decisions in reconstruction of a previous exposure. PMID:2792041

    The selection of representative areas to be analyzed is a common problem in the study of Cultural Heritage items. UV fluorescence photography is an extensively used technique to highlight specific surface features which cannot be observed in visible light (e.g. restored parts or treated with different materials), and it proves to be very effective in the study of historical musical instruments. In this work we propose a new semi-automatic solution for selecting areas with the same perceived color (a simple clue of similar materials) on UV photos, using a specifically designed interactive tool. The proposed method works in two steps: (i) users select a small rectangular area of the image; (ii) program automatically highlights all the areas that have the same color of the selected input. The identification is made by the analysis of the image in HSV color model, the most similar to the human perception. The achievable result is more accurate than a manual selection, because it can detect also points that users do not recognize as similar due to perception illusion. The application has been developed following the rules of usability, and Human Computer Interface has been improved after a series of tests performed by expert and non-expert users. All the experiments were performed on UV imagery of the Stradivari violins collection stored by "Museo del Violino" in Cremona.

    Numerous controlled experiments find that elevated ground-level ozone concentrations ([O3]) damage crops and reduce yield. There have been no estimates of the actual yield losses in the field in the United States from [O3], even though such estimates would be valuable for projections of future food production and for cost–benefit analyses of reducing ground-level [O3]. Regression analysis of historical yield, climate, and [O3] data for the United States were used to determine the loss of production due to O3 for maize (Zea mays) and soybean (Glycine max) from 1980 to 2011, showing that over that period production of rain-fed fields of soybean and maize were reduced by roughly 5% and 10%, respectively, costing approximately $9 billion annually. Maize, thought to be inherently resistant to O3, was at least as sensitive as soybean to O3 damage. Overcoming this yield loss with improved emission controls or more tolerant germplasm could substantially increase world food and feed supply at a time when a global yield jump is urgently needed.

  10. Reaching out to people struggling with their lives: a discourse analysis of answers from Internet-based services in Norway and Sweden

    PubMed Central

    Andersen, Anders Johan W; Svensson, Tommy

    2012-01-01

    The Internet has enlarged the scope of human communication, opening new avenues for connecting with people who are struggling with their lives. This article presents a discourse analysis of 101 responses to 98 questions that were posted on 14 different Internet-based mental health services in Norway and Sweden. We aimed to examine and describe the dominant understandings and favored recommendations in the services’ answers, and we reflected upon the social consequences of those answers. The services generally understood life struggles as an abnormal state of mind, life rhythms, or self-reinforcing loops. Internet-based mental health services primarily counsel service users to seek help, talk to health care professionals face-to-face, and discuss their life struggles openly and honestly. They also urge service users to take better care of themselves and socialize with other people. However, such answers might enhance the individualization of life problems, masking social origin and construction. Consequently, the services are challenged to include social explanations in their answers and strengthen their responsibility to amplify peoples’ messages at a societal level. Potentially, such answers could strengthen democratic structures and put pressure on social equity. PMID:23049282

  11. The medicalisation of 'tall' girls: A discourse analysis of medical literature on the use of synthetic oestrogen to reduce female height.

    Rayner, Jo-Anne; Pyett, Priscilla; Astbury, Jill

    2010-09-01

    Endocrine research in the 1930s increased and extended the use of sex hormones as medical therapies in an unprecedented way, especially for female ailments. In the 1950s the therapeutic use of sex hormones extended to the treatment of 'tall' girls. Ambiguity in the definition of the 'tall' girl, the arbitrary nature of the treatment decision, and diversity in the therapeutic regimes highlight the problematic nature of this medical practice. Using linguistic repertoires to study the political and ideological implications found in the patterned use of language, this paper reports on a discourse analysis of the medical literature on treatment of tall girls between the 1950s and 1990s, when this treatment was at its peak. Three linguistic repertoires emerged: the institutional authority of medicine to determine the 'abnormality' of tall stature in females; the clinical knowledge and experience in the diagnosis of medical risk associated with tall stature in women; and using hormones as cosmetic therapy to (re)produce femininity in tall girls. All three related to the maintenance of the cultural representations and social expectations of femininity. With no evidence of psychological harm associated with tall stature in women, and no long-term studies of either effectiveness or benefit, over five decades clinicians persuaded themselves and their patients that tall stature required therapeutic intervention. The treatment of tall girls with high dose oestrogen must be viewed as the medicalisation of a normal physical attribute adversely related to the social construction of gender. PMID:20678835

  1. From Food Insufficiency towards Trade Dependency: A Historical Analysis of Global Food Availability

    2013-01-01

    Achieving global food security is one of the major challenges of the coming decades. In order to tackle future food security challenges we must understand the past. This study presents a historical analysis of global food availability, one of the key elements of food security. By calculating national level dietary energy supply and production for nine time steps during 1965–2005 we classify countries based on their food availability, food self-sufficiency and food trade. We also look at how diets have changed during this period with regard to supply of animal based calories. Our results show that food availability has increased substantially both in absolute and relative terms. The percentage of population living in countries with sufficient food supply (>2500 kcal/cap/d) has almost doubled from 33% in 1965 to 61% in 2005. The population living with critically low food supply (<2000 kcal/cap/d) has dropped from 52% to 3%. Largest improvements are seen in the MENA region, Latin America, China and Southeast Asia. Besides, the composition of diets has changed considerably within the study period: the world population living with high supply of animal source food (>15% of dietary energy supply) increased from 33% to over 50%. While food supply has increased globally, food self-sufficiency (domestic production>2500 kcal/cap/d) has not changed remarkably. In the beginning of the study period insufficient domestic production meant insufficient food supply, but in recent years the deficit has been increasingly compensated by rising food imports. This highlights the growing importance of food trade, either for food supply in importing countries or as a source of income for exporters. Our results provide a basis for understanding past global food system dynamics which, in turn, can benefit research on future food security. PMID:24367545

    Benzene is an aromatic hydrocarbon that, with sufficient cumulative lifetime doses, can cause acute myelogenous leukemia. Because of its volatility and solvent properties, it was used in the printing industry in inks, ink solvents, and cleaning agents from the 1930s to the 1970s. This analysis represents the first known attempt to gather and synthesize the available data on historical airborne benzene concentrations in printing facilities and exposures to pressmen. The sources of fugitive benzene vapors from printing operations have been identified as evaporation from ink fountains, exposed sections of the printing cylinder, the paper web, the paper post exit, and spilled ink. In addition, specific activities that could lead to benzene exposure, such as filling the fountains, using solvents to clean the press, and using solvents as personal cleaning agents, potentially occurred multiple times per work period. Eighteen studies were identified that reported workplace airborne concentrations in printing facilities between 1938 and 2006. Typical benzene air concentrations, considering both personal and area samples of various durations, were as high as 200 p.p.m. in the 1930s through the 1950s, 3-35 p.p.m. in the 1960s, 1.3-16 p.p.m. in the 1970s, 0.013-1 in the 1980s, and far less than 1 p.p.m. in the 1990s and 2000s. The decrease in benzene air concentrations by the late 1970s was likely to be linked to the decreased benzene content of printing materials, increased engineering controls, and to more stringent occupational exposure limits.

  3. PIXE analysis of historical paintings: Is the gain worth the risk?

    The PIXE analysis of easel paintings constitutes a challenging task. Despite recognized merits and a few emblematic applications, PIXE has never been routinely applied to these fragile, complex and precious targets. The present work discusses the place of PIXE in the study of easel paintings and opens up perspectives for a more systematic usage of this analytical technique. Progress achieved since decades in the implementation of PIXE to study such fragile cultural heritage artefacts is reviewed, notably at the LABEC laboratory in Italy and at the AGLAE facility of the C2RMF in France. Two specific techniques developed for paintings are detailed and exemplified on Renaissance painting masterpieces: differential PIXE for paint layers depth profiling and multi-scale elemental mapping for the imaging of pigment distribution. Beam-induced damage, a major concern, notably depends on the employed beam fluence in particle/cm2 or μC/cm2. After recalling previous works on damage induced in chemical products comparable to pigments, we present the behaviour under different fluences of protons of a few MeV (1-300 μC/cm2) of targets having high resemblance to historical easel paintings: pellets of specially synthesized lead white pigments, layers of lead white mixed with linseed oil and areas containing lead white of two 19th century paintworks. The results shed new lights on the behaviour of paintworks under the beam and pave the way to strategies for damage mitigation. In particular, the lowering of PIXE performance induced by the decrease of the beam fluence sets a trade-off between risk of damage and gained information which also impacts the PIXE scanning protocol for paintings. As an illustration of an adequate adjustment of this balance, we report the exploratory application of PIXE mapping to a large area of a 19th century easel painting without damage. The recorded elemental maps are compared to elemental maps collected on the same area using laboratory-based scanning XRF.

  4. Analysis of historical residential air-conditioning equipment sizing using monitored data

    Monitored data were analyzed to determine whether residential air conditioners in the Pacific Northwest historically have been sized properly to meet or slightly exceed actual cooling requirements. Oversizing air-conditioning equipment results in a loss of efficiency because of increased cycling and also lowers humidity control. Larger air conditioners are also more expensive to purchase. On the other hand, the penalty of undersizing air-conditioning equipment may be some loss of comfort during extremely hot weather. of comfort during extremely hot weather. The monitored data consist of hourly space-conditioning electrical energy use and internal air temperature data collected during the past 7 years from 75 residences in the Pacific Northwest. These residence are equipped with central air conditioners or heat pumps. The periods with the highest cooling energy use were analyzed for each site. A standard industry sizing methodology (Manual J published by Air Conditioning Contractors of America) was used for each site to determine a sizing estimate. Both the sizing the recommendation based on Manual J and peak monitored loads are compared to capacity of the installed equipment for each site to study how the actual capacities differed from both the estimate of proper sizing and from actual demands. The characteristics of the maximum cooling loads are analyzed here to determine which conditions put the highest demand on the air conditioner. Specifically, internal air temperature data are used to determine when the highest cooling loads occur, at constant thermostat settings or when the thermostat was set down. This analysis of monitored data also provides insight into the extent occupant comfort may be affected by undersizing air conditioners.

  5. Petrogenesis of Vesuvius historical lavas constrained by Pearce element ratios analysis and experimental phase equilibria

    NASA Astrophysics Data System (ADS)

    Trigila, Raffaello; De Benedetti, Arnaldo A.

    1993-11-01

    Petrogenesis of Vesuvius historical lavas erupted in the interval 1631-1944 was investigated by petrological methods and experimental phase equilibria. Lavas are strongly porphyritic with principal phenocrysts of clinopyroxene, leucite and calcic plagioclase. Olivine, biotite, Fe?Ti oxides and apatite are present occasionally. Their bulk composition defines a chemical group spanning the leucite-tephrite and phonolite-tephrite regions of the TAS (total alkalies vs. silica) diagram. Through PERs (Pearce element ratios) analysis it has been possible to determine the lava differentiation relationships (controlled by cpx joined by minor lc, plag and Ti-mt) and to estimate the extent of differentiation processes (about 25% of initial mass). Chemistry of cpx indicates a multistage crystallization process in the upper crust. The crystallization environmental parameters deduced from the experimental cpx and liquids are consistent with the existence of a shallow magma chamber within the carbonate rocks of the Triassic basement where the nearly dry Vesuvius magma becomes CO 2 saturated. The generally small volume of the products from single eruptions, and Vesuvius lavas geochemical and petrographic features suggest magma reservoir is zoned with respect to temperature and phenocrysts abundance. The dynamics of magma withdrawal controls mixing of the melt fractions proceeding from different areas of the magma chamber and, therefore, it produces the within-flow chemical differences. Chemical variations among the lavas of different eruptive cycles are instead believed to be controlled essentially by the speed of magma ascent through the upper crust allowing differential removals of cpx phenocrysts crystallized from the magma on its way to the surface.

  6. Rethinking historical trauma.

    PubMed

    Kirmayer, Laurence J; Gone, Joseph P; Moses, Joshua

    2014-06-01

    Recent years have seen the rise of historical trauma as a construct to describe the impact of colonization, cultural suppression, and historical oppression of Indigenous peoples in North America (e.g., Native Americans in the United States, Aboriginal peoples in Canada). The discourses of psychiatry and psychology contribute to the conflation of disparate forms of violence by emphasizing presumptively universal aspects of trauma response. Many proponents of this construct have made explicit analogies to the Holocaust as a way to understand the transgenerational effects of genocide. However, the social, cultural, and psychological contexts of the Holocaust and of post-colonial Indigenous "survivance" differ in many striking ways. Indeed, the comparison suggests that the persistent suffering of Indigenous peoples in the Americas reflects not so much past trauma as ongoing structural violence. The comparative study of genocide and other forms of massive, organized violence can do much to illuminate both common mechanisms and distinctive features, and trace the looping effects from political processes to individual experience and back again. The ethics and pragmatics of individual and collective healing, restitution, resilience, and recovery can be understood in terms of the self-vindicating loops between politics, structural violence, public discourse, and embodied experience.

    2001-01-01

    This paper examines the importance of evaluating discourse in individuals with a neurogenic language disorder. Discourse analysis is acknowledged as an important tool for speech-language pathologists, although it is often not the assessment tool of choice due to its apparent time-consuming nature and the overwhelming number of options available. The wide range of analyses available to clinicians such as the number of T-units and total words produced or Pragmatic Protocol checklists make it difficult to choose assessment measures. Even more difficult is the decision of where to direct treatment efforts. This paper aims to show that there are a number of levels of discourse analysis available to clinicians and that it is possible to sample a number of different genres in a clinical setting. The significance of the communication partner's contribution is discussed, particularly with regard to the limitations of the therapeutic interaction and the need to assess clients with a range of communication partners. The discourse opportunities we make available to people with communication problems will influence what is possible for them. To achieve this, the benefits of a theory of linguistic analysis, namely, Systemic Functional Linguistics (SFL) [Halliday, M. A. K. (1994). An introduction to functional grammar (2nd ed.). London: Edward Amold.] will be explored. PMID:11322564

    A comparison with respect to possible prognostic factors has been made between a contemporary group of 44 patients with osteosarcoma in Sweden, who received treatment since 1971, and a historical group of 35 such patients treated prior to 1972. Only patients with no evidence of metastases on admission were included in the material. The female/male ratio was lower, but not significantly so, for the contemporary group. The mean age was similar in the two groups. Pain was the most common symptom in both groups. The site patterns differed slightly, although not significantly so, in the two groups, there was a higher ratio of frequency of femoral and lower leg tumors for the historical group than for the contemporary group. The variability in tumor size was greater for the historical group, as was the tumor diameter. The historical group had a greater proportion of osteoblastic tumors and these tended to be more malignant. On the whole the prognosis would be expected to be less favorable for the historical group and there would seem to be a definite risk in using this group as a control group to the adjuvant interferon treated patients.

    One of the challenges for health reform in Asia is the diverse set of socio-economic and political structures, and the related variability in the direction and pace of health systems and policy reform. This paper aims to make comparative observations and analysis of health policy reform in the context of historical change, and considers the implications of these findings for the practice of health policy analysis. We adopt an ecological model for analysis of policy development, whereby health systems are considered as dynamic social constructs shaped by changing political and social conditions. Utilizing historical, social scientific and health literature, timelines of health and history for five countries (Cambodia, Myanmar, Mongolia, North Korea and Timor Leste) are mapped over a 30-50 year period. The case studies compare and contrast key turning points in political and health policy history, and examines the manner in which these turning points sets the scene for the acting out of longer term health policy formation, particularly with regard to the managerial domains of health policy making. Findings illustrate that the direction of health policy reform is shaped by the character of political reform, with countries in the region being at variable stages of transition from monolithic and centralized administrations, towards more complex management arrangements characterized by a diversity of health providers, constituency interest and financing sources. The pace of reform is driven by a country's institutional capability to withstand and manage transition shocks of post conflict rehabilitation and emergence of liberal economic reforms in an altered governance context. These findings demonstrate that health policy analysis needs to be informed by a deeper understanding and questioning of the historical trajectory and political stance that sets the stage for the acting out of health policy formation, in order that health systems function optimally along their own historical pathways.

  11. Ellipsis and discourse coherence

    PubMed Central

    Frazier, Lyn; Clifton, Charles

    2006-01-01

    VP-ellipsis generally requires a syntactically matching antecedent. However, many documented examples exist where the antecedent is not appropriate. Kehler (2000, 2002) proposed an elegant theory which predicts a syntactic antecedent for an elided VP is required only for a certain discourse coherence relation (resemblance) not for cause-effect relations. Most of the data Kehler used to motivate his theory come from corpus studies and thus do not consist of true minimal pairs. We report five experiments testing predictions of the coherence theory, using standard minimal pair materials. The results raise questions about the empirical basis for coherence theory because parallelism is preferred for all coherence relations, not just resemblance relations. Further, strict identity readings, which should not be available when a syntactic antecedent is required, are influenced by parallelism per se, holding the discourse coherence relation constant. This draws into question the causal role of coherence relations in processing VP ellipsis. PMID:16896367

    2014-01-01

    The purpose of this paper is to present some of the contributions of the gender discourse to the bioethical debate, specifically in the field of nursing. At the same time, it will explain the contribution of the different feminist theories to the recognition and respect of human dignity. Basically, it will describe the three fundamental models in the gender discourse: the egalitarian model, the difference model, and the model of reciprocity or complementarity. The starting point is that even though the first two models have made significant contributions in the field of bioethics, they have nonetheless brought with them some deficiencies and reductionisms inherent in their thinking. The complementarity model, on the contrary, when properly understood, allows for the combination of the principles of equality and difference between man and woman, which places it at a much more enriching standpoint within the bioethical debate.

    The National Geophysical Data Center (NGDC) maintains a global historical event database of tsunamis, significant earthquakes, and significant volcanic eruptions. The database includes all tsunami events, regardless of intensity, as well as earthquakes and volcanic eruptions that caused fatalities, moderate damage, or generated a tsunami. Event date, time, location, magnitude of the phenomenon, and socio-economic information are included in the database. Analysis of the NGDC event database reveals that the 21st century began with earthquakes in Gujarat, India (magnitude 7.7, 2001) and Bam, Iran (magnitude 6.6, 2003) that killed over 20,000 and 31,000 people, respectively. These numbers were dwarfed by the numbers of earthquake deaths in Pakistan (magnitude 7.6, 2005-86,000 deaths), Wenchuan, China (magnitude 7.9, 2008-87,652 deaths), and Haiti (magnitude 7.0, 2010-222,000 deaths). The Haiti event also ranks among the top ten most fatal earthquakes. The 21st century has observed the most fatal tsunami in recorded history-the 2004 magnitude 9.1 Sumatra earthquake and tsunami that caused over 227,000 deaths and 10 billion damage in 14 countries. Six years later, the 2011 Tohoku, Japan earthquake and tsunami, although not the most fatal (15,000 deaths and 5,000 missing), could cost Japan's government in excess of 300 billion-the most expensive tsunami in history. Volcanic eruptions can cause disruptions and economic impact to the airline industry, but due to their remote locations, fatalities and direct economic effects are uncommon. Despite this fact, the second most expensive eruption in recorded history occurred in the 21st century-the 2010 Merapi, Indonesia volcanic eruption that resulted in 324 deaths, 427 injuries, and $600 million in damage. NGDC integrates all natural hazard event datasets into one search interface. Users can find fatal tsunamis generated by earthquakes or volcanic eruptions. The user can then link to information about the related runup observations (e.g. maximum wave height) and the source earthquake or volcano. If available, damage photographs and plots of water level data can also be viewed. The data are accessible online via tables, reports, and a new state-of-the-art interactive map viewer. These data and access capabilities help coastal communities assess their risks, identify hazards, and promote public awareness of tsunamis and earthquakes.
