  1. Psychotherapeutic discourse analysis.

    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

  12. Assessing the validity of discourse analysis: transdisciplinary convergence

    NASA Astrophysics Data System (ADS)

    Jaipal-Jamani, Kamini

    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.

  17. 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.

  5. 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.

  6. 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

  7. 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.

  5. 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.

  8. 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.

  10. 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.

  13. 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

  18. 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.

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

    SciTech Connect

    Cowell, Andrew J.; Haack, Jereme N.; McColgin, Dave W.

    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.

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

    PubMed Central

    Hakimnia, Roya; Holmström, Inger K.; Carlsson, Marianne; Höglund, Anna T.

    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.

  3. 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.

  11. 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

  12. Physicians and euthanasia: a Canadian print-media discourse analysis of physician perspectives

    PubMed Central

    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

    PubMed Central

    Gobeill, Julien; Tbahriti, Imad; Ehrler, Frédéric; Mottaz, Anaïs; Veuthey, Anne-Lise; Ruch, Patrick

    2008-01-01

    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

    PubMed Central

    Andermo, Susanne; Sundberg, Tobias; Forsberg, Christina; Falkenberg, Torkel

    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

  2. Computer-Supported Collaborative Inquiry on Buoyancy: A Discourse Analysis Supporting the "Pieces" Position on Conceptual Change

    NASA Astrophysics Data System (ADS)

    Turcotte, Sandrine

    2012-12-01

    This article describes in detail a conversation analysis of conceptual change in a computer-supported collaborative learning environment. Conceptual change is an essential learning process in science education that has yet to be fully understood. While many models and theories have been developed over the last three decades, empirical data to support them are scarce. The present paper aims to provide such evidence. To this end, the article first reviews seven proposed models of conceptual change before it recalls the main ideas behind the two different positions on conceptual change, the pieces (diSessa 2008) versus coherence (Vosniadou et al. 2008) positions. Then, the article presents and discusses how a close discourse analysis of asynchronous collaborative conversations between grade 5 and 6 students on buoyancy and relative density provides further empirical evidence of the knowledge in pieces position.

  3. 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.

    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

    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.

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

    PubMed

    Borgstrom, Erica; Walter, Tony

    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.

  6. 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.

    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.

  8. 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

  10. 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.

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

    PubMed Central

    Chaney, Paul; Wincott, Daniel

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

    PubMed

    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.

    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.

  7. It cuts both ways: an analysis of the psychological discourse on self-injury from a linguistic point of view.

    PubMed

    Bar-On, Vered

    2014-10-01

    This article proposes an analysis of the phenomenon of self-injury through the prism of current linguistic theories. The author uses the clinical distinctions made by Roman Jakobson between metonymic and metaphoric aphasia to suggest that the psychological community and those who harm themselves are participating in separate "language games." While the clinical "language game" is characterized by the dominance of metaphor and a conception stressing the hierarchy between metaphor and metonymy, the "language game" of self-mutilators is dominated by metonymy. The author explores the clinical implications of understanding the language game of those who injure themselves as metonymic. PMID:25247287

  11. 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.

  20. Honeymoon, medical treatment or big business? An analysis of the meanings of the term “reproductive tourism” in German and Israeli public media discourses

    PubMed Central

    2013-01-01

    Background/Introduction Infertile couples that travel to another country for reproductive treatment do not refer to themselves as “reproductive tourists”. They might even be offended by this term. “Tourism” is a metaphor with hidden connotations. We will analyze these connotations in public media discourses on “reproductive tourism” in Israel and Germany. We chose to focus on these two countries since legal, ethical and religious restrictions give couples a similar motivation to travel for reproductive care, while the cultural backgrounds and conceptions of reproduction are different. Results Our research shows that the use of the metaphor “reproductive treatment” and its hidden messages depends on the writers’ intention and the target population. Although the phenomenon of patients travelling for reproductive treatment can fit into the definitions of tourism, the term emphasizes aspects that do not reflect patients’ reality. In both the German and the Israeli public media debate the term “reproductive tourism” is either used to criticize the economic aspects of the phenomenon or to attract patients as potential clients. Conclusions Ethicists should be cautious when borrowing metaphors like “reproductive tourism” from the public debate. Our findings support Penning’s suggestion to use instead an unloaded term like cross-border reproductive care to describe the phenomenon in a more neutral way and to make it explicit whenever criticism is necessary.

    Öresland, Stina; Friberg, Febe; Määttä, Sylvia; Öhlen, Joakim

    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.

    PubMed

    Ska, Bernadette; Duong, Anh

    2005-06-01

    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

    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.

    Error analysis is the systematic determination of uncertainties in model predictions due to all possible sources of variability. The objective of these studies in error analysis has been to investigate phenomena associated with prediction uncertainty over as broad a range of ecosystem models as possible, in order to: (1) develop guidelines that will permit the design of experiments and models which minimize prediction error; and (2) develop and test error analysis methodologies and make these available to ecosystem modelers and researchers. The approach to the study of model error has been inductive. A Monte Carlo simulation approach has been applied to a variety of individual models and general patterns that would be applicable across a broad range of ecological models looked for. The purpose of this paper is to review current progress in error analysis of ecological models.

    Graesser, Arthur C; McNamara, Danielle S

    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.

    SciTech Connect

    1980-06-01

    The Energy Policy and Conservation Act (EPCA) mandated that minimum energy efficiency standards be established for classes of refrigerators and refrigerator-freezers, freezers, clothes dryers, water heaters, room air conditioners, home heating equipment, kitchen ranges and ovens, central air conditioners, and furnaces. EPCA requires that standards be designed to achieve the maximum improvement in energy efficiency that is technologically feasible and economically justified. Following the introductory chapter, Chapter Two describes the methodology used in the economic analysis and its relationship to legislative criteria for consumer product efficiency assessment; details how the CPES Value Model systematically compared and evaluated the economic impacts of regulation on the consumer, manufacturer and Nation. Chapter Three briefly displays the results of the analysis and lists the proposed performance standards by product class. Chapter Four describes the reasons for developing a baseline forecast, characterizes the baseline scenario from which regulatory impacts were calculated and summarizes the primary models, data sources and assumptions used in the baseline formulations. Chapter Five summarizes the methodology used to calculate regulatory impacts; describes the impacts of energy performance standards relative to the baseline discussed in Chapter Four. Also discussed are regional standards and other program alternatives to performance standards. Chapter Six describes the procedure for balancing consumer, manufacturer, and national impacts to select standard levels. Details of models and data bases used in the analysis are included in Appendices A through K.

    Analysis of the material protection, control, and accountability (MPC&A) system is necessary to understand the limits and vulnerabilities of the system to internal threats. A self-appraisal helps the facility be prepared to respond to internal threats and reduce the risk of theft or diversion of nuclear material. The material control and accountability (MC&A) system effectiveness tool (MSET) fault tree was developed to depict the failure of the MPC&A system as a result of poor practices and random failures in the MC&A system. It can also be employed as a basis for assessing deliberate threats against a facility. MSET uses fault tree analysis, which is a top-down approach to examining system failure. The analysis starts with identifying a potential undesirable event called a 'top event' and then determining the ways it can occur (e.g., 'Fail To Maintain Nuclear Materials Under The Purview Of The MC&A System'). The analysis proceeds by determining how the top event can be caused by individual or combined lower level faults or failures. These faults, which are the causes of the top event, are 'connected' through logic gates. The MSET model uses AND-gates and OR-gates and propagates the effect of event failure using Boolean algebra. To enable the fault tree analysis calculations, the basic events in the fault tree are populated with probability risk values derived by conversion of questionnaire data to numeric values. The basic events are treated as independent variables. This assumption affects the Boolean algebraic calculations used to calculate results. All the necessary calculations are built into the fault tree codes, but it is often useful to estimate the probabilities manually as a check on code functioning. The probability of failure of a given basic event is the probability that the basic event primary question fails to meet the performance metric for that question. The failure probability is related to how well the facility performs the task identified in that basic event over time (not just one performance or exercise). Fault tree calculations provide a failure probability for the top event in the fault tree. The basic fault tree calculations establish a baseline relative risk value for the system. This probability depicts relative risk, not absolute risk. Subsequent calculations are made to evaluate the change in relative risk that would occur if system performance is improved or degraded. During the development effort of MSET, the fault tree analysis program used was SAPHIRE. SAPHIRE is an acronym for 'Systems Analysis Programs for Hands-on Integrated Reliability Evaluations.' Version 1 of the SAPHIRE code was sponsored by the Nuclear Regulatory Commission in 1987 as an innovative way to draw, edit, and analyze graphical fault trees primarily for safe operation of nuclear power reactors. When the fault tree calculations are performed, the fault tree analysis program will produce several reports that can be used to analyze the MPC&A system. SAPHIRE produces reports showing risk importance factors for all basic events in the operational MC&A system. The risk importance information is used to examine the potential impacts when performance of certain basic events increases or decreases. The initial results produced by the SAPHIRE program are considered relative risk values. None of the results can be interpreted as absolute risk values since the basic event probability values represent estimates of risk associated with the performance of MPC&A tasks throughout the material balance area (MBA). The RRR for a basic event represents the decrease in total system risk that would result from improvement of that one event to a perfect performance level. Improvement of the basic event with the greatest RRR value produces a greater decrease in total system risk than improvement of any other basic event. Basic events with the greatest potential for system risk reduction are assigned performance improvement values, and new fault tree calculations show the improvement in total system risk. The ope

  5. Science learning in the context of discourse

    NASA Astrophysics Data System (ADS)

    do Nascimento, Silvania Sousa

    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.

  6. Power discourses of fish death: case of linnunsuo peat production.

    PubMed

    Mustonen, Tero

    2014-03-01

    This article explores the peat production impacts on Jukajoki river in Finland by implementing discourse analysis. Four discourses are explored: state truth statements; company statements that are in close proximity of state power; discourses provided by the local community Selkie, who provided counter-narratives to the official views; and finally media and related discourses. In conclusion, the discourses by the state and closely related actors (A-B) comprised implementation of their power and justifying it at the expense of those who are excluded from such power, in this case the village. The village narrative (C) contains elements that strongly contradict the statements provided by those with power. The results indicate local communities should be taken more seriously. The systematic denial of local peoples' rights should be reviewed, and local participation in environmental permit assessments implemented. PMID:23852881

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

    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.

  14. Uncertainty analysis

    SciTech Connect

    Thomas, R.E.

    1982-03-01

    An evaluation is made of the suitability of analytical and statistical sampling methods for making uncertainty analyses. The adjoint method is found to be well-suited for obtaining sensitivity coefficients for computer programs involving large numbers of equations and input parameters. For this purpose the Latin Hypercube Sampling method is found to be inferior to conventional experimental designs. The Latin hypercube method can be used to estimate output probability density functions, but requires supplementary rank transformations followed by stepwise regression to obtain uncertainty information on individual input parameters. A simple Cork and Bottle problem is used to illustrate the efficiency of the adjoint method relative to certain statistical sampling methods. For linear models of the form Ax=b it is shown that a complete adjoint sensitivity analysis can be made without formulating and solving the adjoint problem. This can be done either by using a special type of statistical sampling or by reformulating the primal problem and using suitable linear programming software.

  12. Well, Now, Okey Dokey: English Discourse Markers in Spanish Language Medical Consultations

    PubMed Central

    Vickers, Caroline H.; Goble, Ryan

    2013-01-01

    The purpose of this paper is to examine use of English discourse markers in otherwise Spanish language consultations. Data is derived from an audio-recorded corpus of Spanish language consultations that took place in a small community clinic in the United States as well as post-consultation interviews with patients and providers. Through quantification of the use of discourse makers in the corpus and discourse analysis of transcripts, we demonstrate that English-speaking dominant medical providers use English discourse markers more frequently and with a broader range of functions than do Spanish-speaking dominant medical providers and patients. We argue that such use of English discourse markers serves to exacerbate the power relationship between providers and patients even though the use of English discourse markers does not cause overt miscommunication in the ongoing interaction. Implications for providers who use a second language in their medical consultations are discussed. PMID:24347670

    PubMed

    Graesser, A C; Millis, K K; Zwaan, R A

    1997-01-01

    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.

    2010-03-01

    In May 2006 the Gardasil vaccine was approved for implementation in the United States to prohibit the spread of four strains of the human papillomavirus (HPV) that can lead to cervical cancer. Through a poststructural feminist reading, I critique ideologies at play throughout the Food and Drug Administration (FDA) approval hearing for this vaccine. I explore the conditions that gave rise to the adoption of the Gardasil vaccine as evidenced in the hearing transcript, and probe contradictions between choices the FDA enacted for the feminine body with those recommendations from lead scientists of Merck that urged the inclusion of males in the vaccination process. Along the way, I respond to appeals from scholars to address matters of health policy formation and implementation as critical and underexplored dimensions of health communication. I offer a vision that makes way for proactive engagement of males in reproductive and sexual health, particularly as the FDA delayed vaccine approval for males until 2009. PMID:20390678

    This paper takes a Health Education perspective to analyze a debate forum on the Brazilian Internet site entitled "Universo On-Line", in which the following questions were addressed: "Do you believe that marijuana is harmful to one's health?" "In your opinion, should marijuana use be decriminalized?" By applying qualitative discourse analysis techniques to responses from the forum, we were able to identify six main types of discourse, reflecting the opinions of six "collective subjects" concerning drugs, health, disease, and freedom and existing as social representations in the current Brazilian collective imagination. Research on these social representations allows one to establish criteria for intervention in the field of Health Education. PMID:10578087

  7. Relationship between selected discourse strategies and student critical thinking.

    PubMed

    Rossignol, M

    1997-12-01

    This study investigated the relationship between use of selected discourse strategies and level of student critical thinking in nursing clinical post-conferences. Selected discourse strategies included: (a) teacher high-level questions, (b) teacher elaboration of student ideas, (c) teacher probing questions, (d) student participation, and (e) student-to-student participation. The level of student critical thinking was defined as the quartile ranking of students (N = 57) on the Watson-Glaser Critical Thinking Appraisal summative measure. It was hypothesized that greater use of discourse strategies would be associated with high-levels of student critical thinking. All discourse strategies were significantly associated (p < .0001) to student quartile ranking for one taping session (Conference II). Further analysis, however, revealed ambiguous patterns of two-way associations. The more consistent findings suggested a conceptual relationship between less student talk and student-to-student talk and high-levels of student critical thinking. PMID:9413817

  14. Creativity in theoretical physics: A situational analysis of the fifth Solvay Council on Physics, 1927

    NASA Astrophysics Data System (ADS)

    First, Leili K.

    This dissertation investigates the intersections and interactions of factors which enhance and inhibit creativity in theoretical physics research, using a situational analysis of the fifth Solvay Council on Physics of 1927 (Solvay 1927), a pivotal point in the history of quantum physics. Situational analysis is a postmodern variant of the grounded theory method which views a situation as the unit of analysis and adds situational mapping as an analytic tool. This method specifically works against normalizing or simplifying the points of view, instead drawing out diversity, complexity, and contradiction. It results in "theorizing" rather than theory. This research differs from other analyses of the development of quantum mechanics in looking at technical issues as well as individual, collective, and societal factors. Data examined in this historical analysis includes theoretical papers, conference proceedings, personal letters, and commentary and analysis, both contemporaneous and modern. Literature related to scientific creativity was also consulted. Mapping the situation as a master discourse of Niels Bohr overlapping and interacting with co-existent major discourses on matrix mechanics/Copenhagen interpretation, wave mechanics, and the pilot-wave theory resulted in the most descriptive illustration of the factors influencing scientific creativity before and after Solvay 1927. The master discourse strongly influenced the major discourses and generated the "Copenhagen spirit" which effectively marginalized discourses other than matrix mechanics/Copenhagen interpretation after Solvay 1927.

  1. 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.

    Dér, Csilla Ilona; Markó, Alexandra

    2010-01-01

    This study is the first attempt at detecting formal and positional characteristics of single-word simple discourse markers in a spontaneous speech sample of Hungarian. In the first part of the research, theoretical claims made in the relevant literature were tested. The data did not confirm or only partially confirmed the claims that Hungarian discourse markers (i) occur in turn-initial position and (ii) are prosodically independent, that is, are flanked by a pause on either side. In the second part, we looked at word forms both occurring as discourse markers and having syntactic functions in order to determine the features and cues which help us during speech perception to identify and distinguish between syntactic and discourse marking functions. The points of analysis were as follows: the position of the given word form in the clause, the degree of lenition in its articulation, the duration of the word form, the modulation of fundamental frequency, and the occurrence of sentence stress, if any, on the word form at hand. The results show that one or the other, or some combination, of these various factors may play a role in the perception process in certain instances only; this suggests that other parameters, yet to be explored, are also involved in the identification of these functions.

    NASA s Constellation Program employs a strategic analysis methodology in providing an integrated analysis capability of Lunar exploration scenarios and to support strategic decision-making regarding those scenarios. The strategic analysis methodology integrates the assessment of the major contributors to strategic objective satisfaction performance, affordability, and risk and captures the linkages and feedbacks between all three components. Strategic analysis supports strategic decision making by senior management through comparable analysis of alternative strategies, provision of a consistent set of high level value metrics, and the enabling of cost-benefit analysis. The tools developed to implement the strategic analysis methodology are not element design and sizing tools. Rather, these models evaluate strategic performance using predefined elements, imported into a library from expert-driven design/sizing tools or expert analysis. Specific components of the strategic analysis tool set include scenario definition, requirements generation, mission manifesting, scenario lifecycle costing, crew time analysis, objective satisfaction benefit, risk analysis, and probabilistic evaluation. Results from all components of strategic analysis are evaluated a set of pre-defined figures of merit (FOMs). These FOMs capture the high-level strategic characteristics of all scenarios and facilitate direct comparison of options. The strategic analysis methodology that is described in this paper has previously been applied to the Space Shuttle and International Space Station Programs and is now being used to support the development of the baseline Constellation Program lunar architecture. This paper will present an overview of the strategic analysis methodology and will present sample results from the application of the strategic analysis methodology to the Constellation Program lunar architecture.

  6. The discourse of causal explanations in school science

    NASA Astrophysics Data System (ADS)

    Slater, Tammy Jayne Anne

    Researchers and educators working from a systemic functional linguistic perspective have provided a body of work on science discourse which offers an excellent starting point for examining the linguistic aspects of the development of causal discourse in school science, discourse which Derewianka (1995) claimed is critical to success in secondary school. No work has yet described the development of causal language by identifying the linguistic features present in oral discourse or by comparing the causal discourse of native and non-native (ESL) speakers of English. The current research responds to this gap by examining the oral discourse collected from ESL and non-ESL students at the primary and high school grades. Specifically, it asks the following questions: (1) How do the teachers and students in these four contexts develop causal explanations and their relevant taxonomies through classroom interactions? (2) What are the causal discourse features being used by the students in these four contexts to construct oral causal explanations? The findings of the social practice analysis showed that the teachers in the four contexts differed in their approaches to teaching, with the primary school mainstream teacher focusing largely on the hands-on practice , the primary school ESL teacher moving from practice to theory, the high school mainstream teacher moving from theory to practice, and the high school ESL teacher relying primarily on theory. The findings from the quantitative, small corpus approach suggest that the developmental path of cause which has been identified in the writing of experts shows up not only in written texts but also in the oral texts which learners construct. Moreover, this move appears when the discourse of high school ESL and non-ESL students is compared, suggesting a developmental progression in the acquisition of these features by these students. The findings also reveal that the knowledge constructed, as shown by the concept maps created from the discourse, follows a developmental path similar to the linguistic causal path, from the concrete, hands-on, observable items to more abstract, theoretical concepts. This study is the first systemic functional comparison of the oral discourse of primary and secondary learners as well as the first to compare ESL and non-ESL speakers in this way, and as such it helps map general trends in causal discourse development.

  7. NASA trend analysis procedures

    NASA Technical Reports Server (NTRS)

    1993-01-01

    This publication is primarily intended for use by NASA personnel engaged in managing or implementing trend analysis programs. 'Trend analysis' refers to the observation of current activity in the context of the past in order to infer the expected level of future activity. NASA trend analysis was divided into 5 categories: problem, performance, supportability, programmatic, and reliability. Problem trend analysis uncovers multiple occurrences of historical hardware or software problems or failures in order to focus future corrective action. Performance trend analysis observes changing levels of real-time or historical flight vehicle performance parameters such as temperatures, pressures, and flow rates as compared to specification or 'safe' limits. Supportability trend analysis assesses the adequacy of the spaceflight logistics system; example indicators are repair-turn-around time and parts stockage levels. Programmatic trend analysis uses quantitative indicators to evaluate the 'health' of NASA programs of all types. Finally, reliability trend analysis attempts to evaluate the growth of system reliability based on a decreasing rate of occurrence of hardware problems over time. Procedures for conducting all five types of trend analysis are provided in this publication, prepared through the joint efforts of the NASA Trend Analysis Working Group.

    2008-04-08

    Washington Safety Management Solutions, LLC developed web-based software to improve the efficiency and consistency of hazard identification and analysis, control selection and classification, and to standardize analysis reporting at Savannah River Site. In the new nuclear age, information technology provides methods to improve the efficiency of the documented safety analysis development process which includes hazard analysis activities. This software provides a web interface that interacts with a relational database to support analysis, record data, and to ensure reporting consistency. A team of subject matter experts participated in a series of meetings to review the associated processes and procedures for requirements and standard practices. Through these meetings, a set of software requirements were developed and compiled into a requirements traceability matrix from which software could be developed. The software was tested to ensure compliance with the requirements. Training was provided to the hazard analysis leads. Hazard analysis teams using the software have verified its operability. The software has been classified as NQA-1, Level D, as it supports the analysis team but does not perform the analysis. The software can be transported to other sites with alternate risk schemes. The software is being used to support the development of 14 hazard analyses. User responses have been positive with a number of suggestions for improvement which are being incorporated as time permits. The software has enforced a uniform implementation of the site procedures. The software has significantly improved the efficiency and standardization of the hazard analysis process.

    Online news, microblogs and other media documents all contain valuable insight regarding events and responses to events. Underlying these documents is the concept of framing, a process in which communicators act (consciously or unconsciously) to construct a point of view that encourages facts to be interpreted by others in a particular manner. As media discourse evolves, how topics and documents are framed can undergo change, shifting the discussion to different viewpoints or rhetoric. What causes these shifts can be difficult to determine directly; however, by linking secondary datasets and enabling visual exploration, we can enhance the hypothesis generation process. In this paper, we present a visual analytics framework for event cueing using media data. As discourse develops over time, our framework applies a time series intervention model which tests to see if the level of framing is different before or after a given date. If the model indicates that the times before and after are statistically significantly different, this cues an analyst to explore related datasets to help enhance their understanding of what (if any) events may have triggered these changes in discourse. Our framework consists of entity extraction and sentiment analysis as lenses for data exploration and uses two different models for intervention analysis. To demonstrate the usage of our framework, we present a case study on exploring potential relationships between climate change framing and conflicts in Africa. PMID:26529702

  10. ENHANCED UNCERTAINTY ANALYSIS FOR SRS COMPOSITE ANALYSIS

    Smith, F.; Phifer, M.

    2011-06-30

    The Composite Analysis (CA) performed for the Savannah River Site (SRS) in 2009 (SRS CA 2009) included a simplified uncertainty analysis. The uncertainty analysis in the CA (Smith et al. 2009b) was limited to considering at most five sources in a separate uncertainty calculation performed for each POA. To perform the uncertainty calculations in a reasonable amount of time, the analysis was limited to using 400 realizations, 2,000 years of simulated transport time, and the time steps used for the uncertainty analysis were increased from what was used in the CA base case analysis. As part of the CA maintenance plan, the Savannah River National Laboratory (SRNL) committed to improving the CA uncertainty/sensitivity analysis. The previous uncertainty analysis was constrained by the standard GoldSim licensing which limits the user to running at most four Monte Carlo uncertainty calculations (also called realizations) simultaneously. Some of the limitations on the number of realizations that could be practically run and the simulation time steps were removed by building a cluster of three HP Proliant windows servers with a total of 36 64-bit processors and by licensing the GoldSim DP-Plus distributed processing software. This allowed running as many as 35 realizations simultaneously (one processor is reserved as a master process that controls running the realizations). These enhancements to SRNL computing capabilities made uncertainty analysis: using 1000 realizations, using the time steps employed in the base case CA calculations, with more sources, and simulating radionuclide transport for 10,000 years feasible. In addition, an importance screening analysis was performed to identify the class of stochastic variables that have the most significant impact on model uncertainty. This analysis ran the uncertainty model separately testing the response to variations in the following five sets of model parameters: (a) K{sub d} values (72 parameters for the 36 CA elements in sand and clay), (b) Dose Parameters (34 parameters), (c) Material Properties (20 parameters), (d) Surface Water Flows (6 parameters), and (e) Vadose and Aquifer Flow (4 parameters). Results provided an assessment of which group of parameters is most significant in the dose uncertainty. It was found that K{sub d} and the vadose/aquifer flow parameters, both of which impact transport timing, had the greatest impact on dose uncertainty. Dose parameters had an intermediate level of impact while material properties and surface water flows had little impact on dose uncertainty. Results of the importance analysis are discussed further in Section 7 of this report. The objectives of this work were to address comments received during the CA review on the uncertainty analysis and to demonstrate an improved methodology for CA uncertainty calculations as part of CA maintenance. This report partially addresses the LFRG Review Team issue of producing an enhanced CA sensitivity and uncertainty analysis. This is described in Table 1-1 which provides specific responses to pertinent CA maintenance items extracted from Section 11 of the SRS CA (2009). As noted above, the original uncertainty analysis looked at each POA separately and only included the effects from at most five sources giving the highest peak doses at each POA. Only 17 of the 152 CA sources were used in the original uncertainty analysis and the simulation time was reduced from 10,000 to 2,000 years. A major constraint on the original uncertainty analysis was the limitation of only being able to use at most four distributed processes. This work expanded the analysis to 10,000 years using 39 of the CA sources, included cumulative dose effects at downstream POAs, with more realizations (1,000) and finer time steps. This was accomplished by using the GoldSim DP-Plus module and the 36 processors available on a new windows cluster. The last part of the work looked at the contribution to overall uncertainty from the main categories of uncertainty variables: K{sub d}s, dose parameters, flow parameters, and material propertie

    This paper provides guidance on how to do a stakeholder analysis, whether the aim is to conduct a policy analysis, predict policy development, implement a specific policy or project, or obtain an organizational advantage in one's dealings with other stakeholders. Using lessons learned from an analysis of alcohol policy development in Hungary, it outlines issues to be considered before undertaking the stakeholder analysis concerning the purpose and time dimensions of interest, the time-frame and the context in which the analysis will be conducted. It outlines advantages and disadvantages of an individual or team approach, and of the use of insiders and outsiders for the analysis. It describes how to identify and approach stakeholders and considers the use of qualitative or quantitative data collection methods for estimating stakeholder positions, levels of interest and influence around an issue. A key message is that the process of data collection and analysis needs to be iterative; the analyst needs to revise and deepen earlier levels of the analysis, as new data are obtained. Different examples of ways of analyzing, presenting and illustrating the information are provided. Stakeholder analysis is a useful tool for managing stakeholders and identifying opportunities to mobilize their support for a particular goal. However, various biases and uncertainties necessitate a cautious approach in using it and applying its results. PMID:11012410

    Analysis of the usages of the term "autonomic nervous disorder" among Japanese physicians and patients suggests that medical terms lack essential meanings. Their meanings vary according to speaker, addressee, and context. Autonomic nervous disorder is a term employed to give different perspectives on the origins and treatment of menopausal problems in Japan. Through its changing meanings, it demonstrates aspects of the process of discourse, the shifts language undergoes because it is embedded in power relations. Through discourse, autonomic nervous disorder serves the purposes of both the powerful and the powerless, creating a debate concerning middle-aged women and the control of biomedicine over them. The Japanese case highlights the importance of separate contexts to the process of discourse. Groups with varying degrees of power establish their points of view in contexts of formal respect at one extreme or informal intimacy at the other, thus enabling sharp debate while maintaining surface harmony.

    The purpose of this accident safety analysis is to document in detail, analyses whose results were reported in summary form in the K Basins Safety Analysis Report WHC-SD-SNF-SAR-001. The safety analysis addressed the potential for release of radioactive and non-radioactive hazardous material located in the K Basins and their supporting facilities. The safety analysis covers the hazards associated with normal K Basin fuel storage and handling operations, fuel encapsulation, sludge encapsulation, and canister clean-up and disposal. After a review of the Criticality Safety Evaluation of the K Basin activities, the following postulated events were evaluated: Crane failure and casks dropped into loadout pit; Design basis earthquake; Hypothetical loss of basin water accident analysis; Combustion of uranium fuel following dryout; Crane failure and cask dropped onto floor of transfer area; Spent ion exchange shipment for burial; Hydrogen deflagration in ion exchange modules and filters; Release of Chlorine; Power availability and reliability; and Ashfall.

  5. Multivariate Analysis in Metabolomics

    Metabolomics aims to provide a global snapshot of all small-molecule metabolites in cells and biological fluids, free of observational biases inherent to more focused studies of metabolism. However, the staggeringly high information content of such global analyses introduces a challenge of its own; efficiently forming biologically relevant conclusions from any given metabolomics dataset indeed requires specialized forms of data analysis. One approach to finding meaning in metabolomics datasets involves multivariate analysis (MVA) methods such as principal component analysis (PCA) and partial least squares projection to latent structures (PLS), where spectral features contributing most to variation or separation are identified for further analysis. However, as with any mathematical treatment, these methods are not a panacea; this review discusses the use of multivariate analysis for metabolomics, as well as common pitfalls and misconceptions.

  6. Canonical information analysis

    Canonical correlation analysis is an established multivariate statistical method in which correlation between linear combinations of multivariate sets of variables is maximized. In canonical information analysis introduced here, linear correlation as a measure of association between variables is replaced by the information theoretical, entropy based measure mutual information, which is a much more general measure of association. We make canonical information analysis feasible for large sample problems, including for example multispectral images, due to the use of a fast kernel density estimator for entropy estimation. Canonical information analysis is applied successfully to (1) simple simulated data to illustrate the basic idea and evaluate performance, (2) fusion of weather radar and optical geostationary satellite data in a situation with heavy precipitation, and (3) change detection in optical airborne data. The simulation study shows that canonical information analysis is as accurate as and much faster than algorithms presented in previous work, especially for large sample sizes. URL:

    The Norwegian Mapping Authority (NMA) has during the last few years had a close cooperation with Norwegian Defence Research Establishment (FFI) in the analysis of space geodetic data using the GEOSAT software. In 2012 NMA has taken over the full responsibility for the GEOSAT software. This implies that FFI stopped being an IVS Associate Analysis Center in 2012. NMA has been an IVS Associate Analysis Center since 28 October 2010. NMA's contributions to the IVS as an Analysis Centers focus primarily on routine production of session-by-session unconstrained and consistent normal equations by GEOSAT as input to the IVS combined solution. After the recent improvements, we expect that VLBI results produced with GEOSAT will be consistent with results from the other VLBI Analysis Centers to a satisfactory level.

    Frame Analysis has come to play an increasingly stronger role in the study of social movements in Sociology and Political Science. While significant steps have been made in providing a theory of frames and framing, a systematic characterization of the frame concept is still largely lacking and there are no rec-ognized criteria and methods that can be used to identify and marshal frame evi-dence reliably and in a time and cost effective manner. Consequently, current Frame Analysis work is still too reliant on manual annotation and subjective inter-pretation. The goal of this paper is to present an approach to the representation, acquisition and analysis of frame evidence which leverages Content Analysis, In-formation Extraction and Semantic Search methods to provide a systematic treat-ment of a Frame Analysis and automate frame annotation.

  10. IAC - INTEGRATED ANALYSIS CAPABILITY

    NASA Technical Reports Server (NTRS)

    Frisch, H. P.

    1994-01-01

    The objective of the Integrated Analysis Capability (IAC) system is to provide a highly effective, interactive analysis tool for the integrated design of large structures. With the goal of supporting the unique needs of engineering analysis groups concerned with interdisciplinary problems, IAC was developed to interface programs from the fields of structures, thermodynamics, controls, and system dynamics with an executive system and database to yield a highly efficient multi-disciplinary system. Special attention is given to user requirements such as data handling and on-line assistance with operational features, and the ability to add new modules of the user's choice at a future date. IAC contains an executive system, a data base, general utilities, interfaces to various engineering programs, and a framework for building interfaces to other programs. IAC has shown itself to be effective in automatic data transfer among analysis programs. IAC 2.5, designed to be compatible as far as possible with Level 1.5, contains a major upgrade in executive and database management system capabilities, and includes interfaces to enable thermal, structures, optics, and control interaction dynamics analysis. The IAC system architecture is modular in design. 1) The executive module contains an input command processor, an extensive data management system, and driver code to execute the application modules. 2) Technical modules provide standalone computational capability as well as support for various solution paths or coupled analyses. 3) Graphics and model generation interfaces are supplied for building and viewing models. Advanced graphics capabilities are provided within particular analysis modules such as INCA and NASTRAN. 4) Interface modules provide for the required data flow between IAC and other modules. 5) User modules can be arbitrary executable programs or JCL procedures with no pre-defined relationship to IAC. 6) Special purpose modules are included, such as MIMIC (Model Integration via Mesh Interpolation Coefficients), which transforms field values from one model to another; LINK, which simplifies incorporation of user specific modules into IAC modules; and DATAPAC, the National Bureau of Standards statistical analysis package. The IAC database contains structured files which provide a common basis for communication between modules and the executive system, and can contain unstructured files such as NASTRAN checkpoint files, DISCOS plot files, object code, etc. The user can define groups of data and relations between them. A full data manipulation and query system operates with the database. The current interface modules comprise five groups: 1) Structural analysis - IAC contains a NASTRAN interface for standalone analysis or certain structural/control/thermal combinations. IAC provides enhanced structural capabilities for normal modes and static deformation analysis via special DMAP sequences. IAC 2.5 contains several specialized interfaces from NASTRAN in support of multidisciplinary analysis. 2) Thermal analysis - IAC supports finite element and finite difference techniques for steady state or transient analysis. There are interfaces for the NASTRAN thermal analyzer, SINDA/SINFLO, and TRASYS II. FEMNET, which converts finite element structural analysis models to finite difference thermal analysis models, is also interfaced with the IAC database. 3) System dynamics - The DISCOS simulation program which allows for either nonlinear time domain analysis or linear frequency domain analysis, is fully interfaced to the IAC database management capability. 4) Control analysis - Interfaces for the ORACLS, SAMSAN, NBOD2, and INCA programs allow a wide range of control system analyses and synthesis techniques. Level 2.5 includes EIGEN, which provides tools for large order system eigenanalysis, and BOPACE, which allows for geometric capabilities and finite element analysis with nonlinear material. Also included in IAC level 2.5 is SAMSAN 3.1, an engineering analysis program which contains a general purpose library of over 600 subroutin

  11. Test Analysis Guidelines

    NASA Technical Reports Server (NTRS)

    Jeng, Frank F.

    2007-01-01

    Development of analysis guidelines for Exploration Life Support (ELS) technology tests was completed. The guidelines were developed based on analysis experiences gained from supporting Environmental Control and Life Support System (ECLSS) technology development in air revitalization systems and water recovery systems. Analyses are vital during all three phases of the ELS technology test: pre-test, during test and post test. Pre-test analyses of a test system help define hardware components, predict system and component performances, required test duration, sampling frequencies of operation parameters, etc. Analyses conducted during tests could verify the consistency of all the measurements and the performance of the test system. Post test analyses are an essential part of the test task. Results of post test analyses are an important factor in judging whether the technology development is a successful one. In addition, development of a rigorous model for a test system is an important objective of any new technology development. Test data analyses, especially post test data analyses, serve to verify the model. Test analyses have supported development of many ECLSS technologies. Some test analysis tasks in ECLSS technology development are listed in the Appendix. To have effective analysis support for ECLSS technology tests, analysis guidelines would be a useful tool. These test guidelines were developed based on experiences gained through previous analysis support of various ECLSS technology tests. A comment on analysis from an experienced NASA ECLSS manager (1) follows: "Bad analysis was one that bent the test to prove that the analysis was right to begin with. Good analysis was one that directed where the testing should go and also bridged the gap between the reality of the test facility and what was expected on orbit."

    2014-01-01

    Although the language we encounter is typically embedded in rich discourse contexts, many existing models of processing focus largely on phenomena that occur sentence-internally. Similarly, most work on children's language learning does not consider how information can accumulate as a discourse progresses. Research in pragmatics, however, points to ways in which each subsequent utterance provides new opportunities for listeners to infer speaker meaning. Such inferences allow the listener to build up a representation of the speakers' intended topic and more generally to identify relationships, structures, and messages that extend across multiple utterances. We address this issue by analyzing a video corpus of child-caregiver interactions. We use topic continuity as an index of discourse structure, examining how caregivers introduce and discuss objects across utterances. For the analysis, utterances are grouped into topical discourse sequences using three annotation strategies: raw annotations of speakers' referents, the output of a model that groups utterances based on those annotations, and the judgments of human coders. We analyze how the lexical, syntactic, and social properties of caregiver-child interaction change over the course of a sequence of topically related utterances. Our findings suggest that many cues used to signal topicality in adult discourse are also available in child-directed speech. PMID:24731080

  3. Asymptotic modal analysis and statistical energy analysis

    NASA Technical Reports Server (NTRS)

    Dowell, Earl H.

    1988-01-01

    Statistical Energy Analysis (SEA) is defined by considering the asymptotic limit of Classical Modal Analysis, an approach called Asymptotic Modal Analysis (AMA). The general approach is described for both structural and acoustical systems. The theoretical foundation is presented for structural systems, and experimental verification is presented for a structural plate responding to a random force. Work accomplished subsequent to the grant initiation focusses on the acoustic response of an interior cavity (i.e., an aircraft or spacecraft fuselage) with a portion of the wall vibrating in a large number of structural modes. First results were presented at the ASME Winter Annual Meeting in December, 1987, and accepted for publication in the Journal of Vibration, Acoustics, Stress and Reliability in Design. It is shown that asymptotically as the number of acoustic modes excited becomes large, the pressure level in the cavity becomes uniform except at the cavity boundaries. However, the mean square pressure at the cavity corner, edge and wall is, respectively, 8, 4, and 2 times the value in the cavity interior. Also it is shown that when the portion of the wall which is vibrating is near a cavity corner or edge, the response is significantly higher.

    Commercial partnerships and organizational constraints, combined with complex systems, may lead to division of hazard analysis across organizations. This division could cause important hazards to be overlooked, causes to be missed, controls for a hazard to be incomplete, or verifications to be inefficient. Each organization s team must understand at least one level beyond the interface sufficiently enough to comprehend integrated hazards. This paper will discuss various ways to properly divide analysis among organizations. The Ares I launch vehicle integrated safety analyses effort will be utilized to illustrate an approach that addresses the key issues and concerns arising from multiple analysis responsibilities.

    A linguistic method for the analysis of small group discourse, was developed and the use of this method on transcripts of commercial air transpot accidents is demonstrated. The method identifies the discourse types that occur and determine their linguistic structure; it identifies significant linguistic variables based upon these structures or other linguistic concepts such as speech act and topic; it tests hypotheses that support significance and reliability of these variables; and it indicates the implications of the validated hypotheses. These implications fall into three categories: (1) to train crews to use more nearly optimal communication patterns; (2) to use linguistic variables as indices for aspects of crew performance such as attention; and (3) to provide guidelines for the design of aviation procedures and equipment, especially those that involve speech.

    In this paper I introduce computational techniques to extend qualitative analysis into the study of large textual datasets. I demonstrate these techniques by using probabilistic topic modeling to analyze a broad sample of 14,952 documents published in major American newspapers from 1980 through 2012. I show how computational data mining techniques can identify and evaluate the significance of qualitatively distinct subjects of discussion across a wide range of public discourse. I also show how examining large textual datasets with computational methods can overcome methodological limitations of conventional qualitative methods, such as how to measure the impact of particular cases on broader discourse, how to validate substantive inferences from small samples of textual data, and how to determine if identified cases are part of a consistent temporal pattern.

    2013-04-01

    Large enrolment science courses play a significant role in educating undergraduate students. The discourse in these classes usually involves an instructor lecturing with little or no student participation, despite calls from current science education reform documents to elicit and utilize students' ideas in teaching. In this study, we used the 5E instructional model to develop and implement four lessons in a large enrolment introductory biology course with multiple opportunities for teacher-student and student-student interaction. Data consisted of video and audio recordings of whole-class and small-group discussions that took place throughout the study. We then used a science classroom discourse framework developed by Mortimer and Scott (2003) to characterize the discursive interactions in each 5E lesson phase. Analysis of the data resulted in two assertions. First, the purpose, communicative approach, patterns of discourse, and teaching interventions were unique to each 5E lesson phase. Second, the type of lesson topic influenced the content of the discourse. We discuss how the findings help characterize the discourse of each phase in a 5E college science lesson and propose a model to understand internalization through discursive interaction using this reform-based approach. We conclude with implications for facilitating discourse in college science lessons and future research. This study provides support for using the discourse framework to characterize discursive interaction in college science courses.

    The CMS experiment expects to manage several Pbytes of data each year during the LHC programme, distributing them over many computing sites around the world and enabling data access at those centers for analysis. CMS has identified the distributed sites as the primary location for physics analysis to support a wide community with thousands potential users. This represents an unprecedented experimental challenge in terms of the scale of distributed computing resources and number of user. An overview of the computing architecture, the software tools and the distributed infrastructure is reported. Summaries of the experience in establishing efficient and scalable operations to get prepared for CMS distributed analysis are presented, followed by the user experience in their current analysis activities.

    Flight Operations Analysis Tool (FLOAT) is a computer program that partly automates the process of assessing the benefits of planning spacecraft missions to incorporate various combinations of launch vehicles and payloads. Designed primarily for use by an experienced systems engineer, FLOAT makes it possible to perform a preliminary analysis of trade-offs and costs of a proposed mission in days, whereas previously, such an analysis typically lasted months. FLOAT surveys a variety of prior missions by querying data from authoritative NASA sources pertaining to 20 to 30 mission and interface parameters that define space missions. FLOAT provides automated, flexible means for comparing the parameters to determine compatibility or the lack thereof among payloads, spacecraft, and launch vehicles, and for displaying the results of such comparisons. Sparseness, typical of the data available for analysis, does not confound this software. FLOAT effects an iterative process that identifies modifications of parameters that could render compatible an otherwise incompatible mission set.

    During normal data taking CMS expects to support potentially as many as 2000 analysis users. Since the beginning of 2008 there have been more than 800 individuals who submitted a remote analysis job to the CMS computing infrastructure. The bulk of these users will be supported at the over 40 CMS Tier-2 centres. Supporting a globally distributed community of users on a globally distributed set of computing clusters is a task that requires reconsidering the normal methods of user support for Analysis Operations. In 2008 CMS formed an Analysis Support Task Force in preparation for large-scale physics analysis activities. The charge of the task force was to evaluate the available support tools, the user support techniques, and the direct feedback of users with the goal of improving the success rate and user experience when utilizing the distributed computing environment. The task force determined the tools needed to assess and reduce the number of non-zero exit code applications submitted through the grid interfaces and worked with the CMS experiment dashboard developers to obtain the necessary information to quickly and proactively identify issues with user jobs and data sets hosted at various sites. Results of the analysis group surveys were compiled. Reference platforms for testing and debugging problems were established in various geographic regions. The task force also assessed the resources needed to make the transition to a permanent Analysis Operations task. In this presentation the results of the task force will be discussed as well as the CMS Analysis Operations plans for the start of data taking.

    1995-12-31

    According to regulations relating to implementation and rise of risk analysis in the petroleum activities issued by the Norwegian Petroleum Directorate, it is mandatory for an operator on the Norwegian Continental Shelf to establish acceptance criteria for environmental risk in the activities and carry out environmental risk analysis. This paper presents a {open_quotes}new{close_quotes} method for environmental risk analysis developed by the company. The objective has been to assist the company to meet rules and regulations and to assess and describe the environmental risk in a systematic manner. In the environmental risk analysis the most sensitive biological resource in the affected area is used to assess the environmental damage. The analytical method is based on the methodology for quantitative risk analysis related to loss of life. In addition it incorporates the effect of seasonal fluctuations in the environmental risk evaluations. The paper is describing the function of the main analytical sequences exemplified through an analysis of environmental risk related to exploration drilling in an environmental sensitive area on the Norwegian Continental Shelf.

    The Bechtel/EDF/Battelle Consortium has recently completed the conceptual design for the Chernobyl New Safe Confinement (NSC). Battelle has the scope of work related to environment and safety of the design. As part of the safety analysis, an ALARA analysis was performed for deconstruction of the major, unstable elements of the Shelter Object over the destroyed Unit 4 of the reactor complex. The major elements addressed in the analysis included the current roof sections and the major beams supporting the roof sections. The analysis was based on the existing configuration of the Shelter Object, the developing conceptual design of the NSC arch structure, the developing conceptual design of the facilities within and associated with the NSC (including handling and processing of deconstructed elements, and waste management), and existing Ukranian regulations and working processes and procedures. KSK (a Ukranian Consortium) is a subcontractor to the Bechtel/EDF/Battelle Consortium and performed much of the dose analysis. The analysis concluded that ALARA could be achieved with appropriate implementation of existing Ukrainian regulations and procedures, and developing conceptual design criteria and features.

    NASA/NESSUS 6.2c is a general-purpose, probabilistic analysis program that computes probability of failure and probabilistic sensitivity measures of engineered systems. Because NASA/NESSUS uses highly computationally efficient and accurate analysis techniques, probabilistic solutions can be obtained even for extremely large and complex models. Once the probabilistic response is quantified, the results can be used to support risk-informed decisions regarding reliability for safety-critical and one-of-a-kind systems, as well as for maintaining a level of quality while reducing manufacturing costs for larger-quantity products. NASA/NESSUS has been successfully applied to a diverse range of problems in aerospace, gas turbine engines, biomechanics, pipelines, defense, weaponry, and infrastructure. This program combines state-of-the-art probabilistic algorithms with general-purpose structural analysis and lifting methods to compute the probabilistic response and reliability of engineered structures. Uncertainties in load, material properties, geometry, boundary conditions, and initial conditions can be simulated. The structural analysis methods include non-linear finite-element methods, heat-transfer analysis, polymer/ceramic matrix composite analysis, monolithic (conventional metallic) materials life-prediction methodologies, boundary element methods, and user-written subroutines. Several probabilistic algorithms are available such as the advanced mean value method and the adaptive importance sampling method. NASA/NESSUS 6.2c is structured in a modular format with 15 elements.

    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

    A software application has been developed to aid law enforcement and government intelligence gathering organizations in the translation and analysis of foreign language documents with potential intelligence content. The Automated Document Analysis System (ADAS) provides the capability to search (data or text mine) documents in English and the most commonly encountered foreign languages, including Arabic. Hardcopy documents are scanned by a high-speed scanner and are optical character recognized (OCR). Documents obtained in an electronic format bypass the OCR and are copied directly to a working directory. For translation and analysis, the script and the language of the documents are first determined. If the document is not in English, the document is machine translated to English. The documents are searched for keywords and key features in either the native language or translated English. The user can quickly review the document to determine if it has any intelligence content and whether detailed, verbatim human translation is required. The documents and document content are cataloged for potential future analysis. The system allows non-linguists to evaluate foreign language documents and allows for the quick analysis of a large quantity of documents. All document processing can be performed manually or automatically on a single document or a batch of documents.

    A package for the automation of the Engineering Analysis (EA) process at the Stennis Space Center has been customized. It provides the ability to assign and track analysis tasks electronically, and electronically route a task for approval. It now provides a mechanism to keep these analyses under configuration management. It also allows the analysis to be stored and linked to the engineering data that is needed to perform the analysis (drawings, etc.). PTC s (Parametric Technology Corp o ration) Windchill product was customized to allow the EA to be created, routed, and maintained under configuration management. Using Infoengine Tasks, JSP (JavaServer Pages), Javascript, a user interface was created within the Windchill product that allows users to create EAs. Not only does this interface allow users to create and track EAs, but it plugs directly into the out-ofthe- box ability to associate these analyses with other relevant engineering data such as drawings. Also, using the Windchill workflow tool, the Design and Data Management System (DDMS) team created an electronic routing process based on the manual/informal approval process. The team also added the ability for users to notify and track notifications to individuals about the EA. Prior to the Engineering Analysis creation, there was no electronic way of creating and tracking these analyses. There was also a feature that was added that would allow users to track/log e-mail notifications of the EA.

  11. [Transcriptome analysis and pharmacogenomics].

    2000-10-01

    Pharmacogenomics is defined as identification of loci which are involved in determining the responsiveness and distinguishing responders and non-responders to a given drug. Genome sequencing, transcriptome and proteome analysis are of particular significance in pharmacogenomics. Sequencing is used to locate polymorphisms, and monitoring of gene expression can provide clues about the genomic response to disease and treatment. The transcriptome analysis can be done by methods of random cDNA sequencing (expressed sequence tag project, body map project, serial analysis of gene expression, etc.), mRNA display (differential display, fluorescent differential display, RNA arbitrary primed PCR, molecular indexing, gene expression fingerprinting, etc.) and differential hybridization (cDNA high density filter, cDNA microarray, oligomicrochip, etc.). We describe the principle and application of trancriptome analysis in pharmacogenomics, especially differential display and cDNA microarray. We used transcriptome analysis to identify therapeutic target genes by studying the change of gene expression in animal models of oxidative stress and hypoxia and found novel drug target candidates through this pharmacogenomic strategy.

    NASA regulations specify that formal risk analysis be performed on a program at each of several milestones. Program risk analysis is discussed as a systems analysis approach, an iterative process (identification, assessment, management), and a collection of techniques. These techniques, which range from extremely simple to complex network-based simulation, are described in this handbook in order to provide both analyst and manager with a guide for selection of the most appropriate technique. All program risk assessment techniques are shown to be based on elicitation and encoding of subjective probability estimates from the various area experts on a program. Techniques to encode the five most common distribution types are given. Then, a total of twelve distinct approaches to risk assessment are given. Steps involved, good and bad points, time involved, and degree of computer support needed are listed. Why risk analysis should be used by all NASA program managers is discussed. Tools available at NASA-MSFC are identified, along with commercially available software. Bibliography (150 entries) and a program risk analysis check-list are provided.

    2015-12-01

    Biosensors first appeared several decades ago to address the need for monitoring physiological parameters such as oxygen or glucose in biological fluids such as blood. More recently, a new wave of biosensors has emerged in order to provide more nuanced and granular information about the composition and function of living cells. Such biosensors exist at the confluence of technology and medicine and often strive to connect cell phenotype or function to physiological or pathophysiological processes. Our review aims to describe some of the key technological aspects of biosensors being developed for cell analysis. The technological aspects covered in our review include biorecognition elements used for biosensor construction, methods for integrating cells with biosensors, approaches to single-cell analysis, and the use of nanostructured biosensors for cell analysis. Our hope is that the spectrum of possibilities for cell analysis described in this review may pique the interest of biomedical scientists and engineers and may spur new collaborations in the area of using biosensors for cell analysis.

  14. Stakeholder analysis: a review.

    PubMed

    Brugha, R; Varvasovszky, Z

    2000-09-01

    The growing popularity of stakeholder analysis reflects an increasing recognition of how the characteristics of stakeholders--individuals, groups and organizations--influence decision-making processes. This paper reviews the origins and uses of stakeholder analysis, as described in the policy, health care management and development literature. Its roots are in the political and policy sciences, and in management theory where it has evolved into a systematic tool with clearly defined steps and applications for scanning the current and future organizational environment. Stakeholder analysis can be used to generate knowledge about the relevant actors so as to understand their behaviour, intentions, interrelations, agendas, interests, and the influence or resources they have brought--or could bring--to bear on decision-making processes. This information can then be used to develop strategies for managing these stakeholders, to facilitate the implementation of specific decisions or organizational objectives, or to understand the policy context and assess the feasibility of future policy directions. Policy development is a complex process which frequently takes place in an unstable and rapidly changing context, subject to unpredictable internal and external factors. As a cross-sectional view of an evolving picture, the utility of stakeholder analysis for predicting and managing the future is time-limited and it should be complemented by other policy analysis approaches.

    2009-12-01

    This report provides the DOE and industry with a general process for analyzing power electronics reliability. The analysis can help with understanding the main causes of failures, downtime, and cost and how to reduce them. One approach is to collect field maintenance data and use it directly to calculate reliability metrics related to each cause. Another approach is to model the functional structure of the equipment using a fault tree to derive system reliability from component reliability. Analysis of a fictitious device demonstrates the latter process. Optimization can use the resulting baseline model to decide how to improve reliability and/or lower costs. It is recommended that both electric utilities and equipment manufacturers make provisions to collect and share data in order to lay the groundwork for improving reliability into the future. Reliability analysis helps guide reliability improvements in hardware and software technology including condition monitoring and prognostics and health management.

    The Velocity Interferometer System for Any Reflector (VISAR) is a widely used diagnostic at Sandia National Laboratories. Although the operating principles of the VISAR are well established, recently deployed systems (such as the fast push-pull and air delay VISAR) require more careful consideration, and many common assumptions about VISAR are coming into question. This report presents a comprehensive review of VISAR analysis to address these issues. Detailed treatment of several interferometer configurations is given to identify important aspects of the operation and characterization of VISAR systems. The calculation of velocity from interferometer measurements is also described. The goal is to derive the standard VISAR analysis relationships, indicate when these relationships are valid, and provide alternative methods when the standard analysis fails.

  1. Nonlinear rotordynamics analysis

    Day, W. B.

    1985-01-01

    The special nonlinearities of the Jeffcott equations in rotordynamics are examined. The immediate application of this analysis is directed toward understanding the excessive vibrations recorded in the LOX pump of the SSME during hot firing ground testing. Deadband, side force and rubbing are three possible sources of inducing nonlinearity in the Jeffcott equations. The present analysis initially reduces these problems to the same mathematical description. A special frequency, named the nonlinear natural frequency is defined and used to develop the solutions of the nonlinear Jeffcott equations as asympotic expansions. This nonlinear natural frequency which is the ratio of the cross-stiffness and the damping, plays a major role in determining response frequencies. Numerical solutions are included for comparison with the analysis. Also, nonlinear frequency-response tables are made for a typical range of values.

    Microarrays are one of the latest breakthroughs in experimental molecular biology, which allow monitoring of gene expression for tens of thousands of genes in parallel and are already producing huge amounts of valuable data. Analysis and handling of such data is becoming one of the major bottlenecks in the utilization of the technology. The raw microarray data are images, which have to be transformed into gene expression matrices, tables where rows represent genes, columns represent various samples such as tissues or experimental conditions, and numbers in each cell characterize the expression level of the particular gene in the particular sample. These matrices have to be analyzed further if any knowledge about the underlying biological processes is to be extracted. In this paper we concentrate on discussing bioinformatics methods used for such analysis. We briefly discuss supervised and unsupervised data analysis and its applications, such as predicting gene function classes and cancer classification as well as some possible future directions.

    Sherry, Lance; Polson, Peter; Feay, Mike; Palmer, Everett; Null, Cynthia H. (Technical Monitor)

    1998-01-01

    Aviation and cognitive science researchers have identified situations in which the pilot's expectations for behavior of autopilot avionics are not matched by the actual behavior of the avionics. These "automation surprises" have been attributed to differences between the pilot's model of the behavior of the avionics and the actual behavior encoded in the avionics software. A formal technique is described for the analysis and measurement of the behavior of the cruise pitch modes of a modern Autopilot. The analysis characterizes the behavior of the Autopilot as situation-action rules. The behavior of the cruise pitch mode logic for a contemporary modern Autopilot was found to include 177 rules, including Level Change (23), Vertical Speed (16), Altitude Capture (50), and Altitude Hold (88). These rules are determined based on the values of 62 inputs. Analysis of the rule-based model also shed light on the factors cited in the literature as contributors to "automation surprises."

    NURSE RESEARCHER publishes a wide range of methodology papers, many of which aim to give guidance to early researchers. Here I comment on two papers. The first, Qualitative case study data analysis: an example from practice ( Houghton et al 2015 ) is clearly comprehendible by novice researchers. The second, Multiple imputation method for handling missing data: A case study of a secondary data analysis study ( Walani and Cleland 2015 ) is a rather different case. This is a useful paper but deals with a complex issue in quantitative data analysis.

    This lab experiment illustrates the use of thermogravimetric analysis (TGA) to perform proximate analysis on a series of coal samples of different rank. Peat and coke are also examined. A total of four exercises are described. These are dry exercises as students interpret previously recorded scans. The weight percent moisture, volatile matter, fixed carbon, and ash content are determined for each sample and comparisons are made. Proximate analysis is performed on a coal sample from a local electric utility. From the weight percent sulfur found in the coal (determined by a separate procedure the Eschka method) and the ash content, students calculate the quantity of sulfur dioxide emissions and ash produced annually by a large coal-fired electric power plant.

    The Solar Energy Research Institute has conducted a limited sensitivity analysis on a System for Projecting the Utilization of Renewable Resources (SPURR). The study utilized the Domestic Policy Review scenario for SPURR agricultural and industrial process heat and utility market sectors. This sensitivity analysis determines whether variations in solar system capital cost, operation and maintenance cost, and fuel cost (biomass only) correlate with intuitive expectations. The results of this effort contribute to a much larger issue: validation of SPURR. Such a study has practical applications for engineering improvements in solar technologies and is useful as a planning tool in the R and D allocation process.

    Zen's challenge for behavior analysis is to explain a repertoire that renders analysis itself meaningless—a result following not from scientific or philosophical arguments but rather from a unique verbal history generated by Zen's methods. Untying Zen's verbal knots suggests how meditation's and koans' effects on verbal behavior contribute to Enlightenment and Sam?dhi. The concept of stimulus singularity is introduced to account for why, within Zen's frame of reference, its methods can be studied but its primary outcomes (e.g., Sam?dhi and Satori) cannot be described in any conventional sense.

    This paper presents an analysis of swimming motion with specific attention given to the flutter kick, the breast-stroke kick, and the breast stroke. The analysis is completely theoretical. It employs a mathematical model of the human body consisting of frustrums of elliptical cones. Dynamical equations are written for this model including both viscous and inertia forces. These equations are then applied with approximated swimming strokes and solved numerically using a digital computer. The procedure is to specify the input of the swimming motion. The computer solution then provides the output displacement, velocity, and rotation or body roll of the swimmer.

  5. When discourses collide: creationism and evolution in the public sphere

    NASA Astrophysics Data System (ADS)

    Dávila, Denise

    2014-12-01

    This review essay focuses on Özgür Ta?k?n's discussion of the theory of evolution (TOE), intelligent design (ID) and the convictions of fundamentalist science educators and students in his paper entitled: An exploratory examination of Islamic values in science education: Islamization of science teaching and learning via constructivism. It examines the competing social discourses of evolution and creationism in the United States, which is partially maintained by national public opinion polls and states' legislation about the TOE in the science curricula. The examination of US social discourses presented here is framed by James Gee's (2008) theory that Discourses with a capital "D," are unconscious and uncritical socially accepted ways of speaking/listening and writing/reading that are merged with "distinctive ways of acting, interacting, valuing, feeling, dressing, thinking, [and] believing…so as to enact specific socially recognizable identities…" (p. 155). Such Discourses identify insiders of and outsiders to religious affiliations and other social or cultural groups. The context of this examination is unique in that is draws from the national conversation about the inclusion of ID alongside of the TOE in the public school science programs. Gee's (2011) concept that Discourses serve as tools of inquiry guides the analysis of video recorded public messages from Bill Nye and Lawrence Krauss as well as Creation Museum president Ken Ham. The analysis and discussion of the national conversation about creationism and public education suggests that the education community must consider the global landscape of science literacy both locally and internationally. It also indicates that preservice and practicing science educators may require special training and support. In order to provide unbiased, religious-resistant, evidence-based science instruction, science educators must understand how to separate church from state regardless of their personal beliefs. They must also know how to navigate conversations about the TOE among diverse communities of learners that include both religiously and non-religiously affiliated students.

  6. Penetrating a wall of introspection: a critical attrition analysis

    NASA Astrophysics Data System (ADS)

    Johannsen, Bjørn Friis; Rump, Camilla Østerberg; Linder, Cedric

    2013-03-01

    This paper presents a critical analysis of student discourse on attrition as it unfolds in interviews on early departure from higher education. A synthesis of relevant studies and modelling done in the field shows that essential aspects affecting attrition and retention can be effectively conceptualized and acted upon in terms of the interplay between student and institution. These aspects were used in combination with James Gee's notion of Discourse models to design a unique framing for interpretation of interviews aimed at bringing out new causal dynamics that lie in this interplay. To illustrate this interpretation, Aristotle's notion of four causes is used. The analysis presented is a study of interviews with seven former physics students about their early departure. This framing of the analysis was necessary because the students' description of how they understood their actions did not explicitly reveal interplay between student and institution. These details lay behind a `wall of introspection' that otherwise posed a serious challenge to the use of student testimony as direct means to identify and address issues of early departure. The results are used to discuss research implications.

    2008-01-01

    Today's complex systems require understanding beyond one person s capability to comprehend. Each system requires a team to divide the system into understandable subsystems which can then be analyzed with an Integrated Hazard Analysis. The team must have both specific experiences and diversity of experience. Safety experience and system understanding are not always manifested in one individual. Group dynamics make the difference between success and failure as well as the difference between a difficult task and a rewarding experience. There are examples in the news which demonstrate the need to connect the pieces of a system into a complete picture. The Columbia disaster is now a standard example of a low consequence hazard in one part of the system; the External Tank is a catastrophic hazard cause for a companion subsystem, the Space Shuttle Orbiter. The interaction between the hardware, the manufacturing process, the handling, and the operations contributed to the problem. Each of these had analysis performed, but who constituted the team which integrated this analysis together? This paper will explore some of the methods used for dividing up a complex system; and how one integration team has analyzed the parts. How this analysis has been documented in one particular launch space vehicle case will also be discussed.

    To impart hands-on training in physics analysis, CMS experiment initiated the concept of CMS Data Analysis School (CMSDAS). It was born over three years ago at the LPC (LHC Physics Centre), Fermilab and is based on earlier workshops held at the LPC and CLEO Experiment. As CMS transitioned from construction to the data taking mode, the nature of earlier training also evolved to include more of analysis tools, software tutorials and physics analysis. This effort epitomized as CMSDAS has proven to be a key for the new and young physicists to jump start and contribute to the physics goals of CMS by looking for new physics with the collision data. With over 400 physicists trained in six CMSDAS around the globe, CMS is trying to engage the collaboration in its discovery potential and maximize physics output. As a bigger goal, CMS is striving to nurture and increase engagement of the myriad talents, in the development of physics, service, upgrade, education of those new to CMS and the career development of younger members. An extension of the concept to the dedicated software and hardware schools is also planned, keeping in mind the ensuing upgrade phase.

    Draper Station Analysis Tool (DSAT) is a computer program, built on commercially available software, for simulating and analyzing complex dynamic systems. Heretofore used in designing and verifying guidance, navigation, and control systems of the International Space Station, DSAT has a modular architecture that lends itself to modification for application to spacecraft or terrestrial systems. DSAT consists of user-interface, data-structures, simulation-generation, analysis, plotting, documentation, and help components. DSAT automates the construction of simulations and the process of analysis. DSAT provides a graphical user interface (GUI), plus a Web-enabled interface, similar to the GUI, that enables a remotely located user to gain access to the full capabilities of DSAT via the Internet and Webbrowser software. Data structures are used to define the GUI, the Web-enabled interface, simulations, and analyses. Three data structures define the type of analysis to be performed: closed-loop simulation, frequency response, and/or stability margins. DSAT can be executed on almost any workstation, desktop, or laptop computer. DSAT provides better than an order of magnitude improvement in cost, schedule, and risk assessment for simulation based design and verification of complex dynamic systems.

    The objective of this study is to develop a new methodology for estimating the reliability of engineering systems that encompass multiple disciplines. The methodology is formulated in the context of the NESSUS probabilistic structural analysis code, developed under the leadership of NASA Glenn Research Center. The NESSUS code has been successfully applied to the reliability estimation of a variety of structural engineering systems. This study examines whether the features of NESSUS could be used to investigate the reliability of systems in other disciplines such as heat transfer, fluid mechanics, electrical circuits etc., without considerable programming effort specific to each discipline. In this study, the mechanical equivalence between system behavior models in different disciplines are investigated to achieve this objective. A new methodology is presented for the analysis of heat transfer, fluid flow, and electrical circuit problems using the structural analysis routines within NESSUS, by utilizing the equivalence between the computational quantities in different disciplines. This technique is integrated with the fast probability integration and system reliability techniques within the NESSUS code, to successfully compute the system reliability of multidisciplinary systems. Traditional as well as progressive failure analysis methods for system reliability estimation are demonstrated, through a numerical example of a heat exchanger system involving failure modes in structural, heat transfer and fluid flow disciplines.

    2008-06-01

    The ATLAS production system has been successfully used to run production of simulation data at an unprecedented scale. Up to 10000 jobs were processed in one day. The experiences obtained operating the system on several grid flavours was essential to perform a user analysis using grid resources. First tests of the distributed analysis system were then performed. In the preparation phase data was registered in the LHC File Catalog (LFC) and replicated in external sites. For the main test, few resources were used. All these tests are only a first step towards the validation of the computing model. The ATLAS management computing board decided to integrate the collaboration efforts in distributed analysis in only one project, GANGA. The goal is to test the reconstruction and analysis software in a large scale Data production using Grid flavors in several sites. GANGA allows trivial switching between running test jobs on a local batch system and running large-scale analyses on the Grid; it provides job splitting and merging, and includes automated job monitoring and output retrieval.

    This document presents the results from the analysis of the shot loading trainer (SLT). This device will be used to test the procedure for installing shot into the annulus of the Project W-320 shipping container. To ensure that the shot is installed uniformly around the container, vibrators will be used to settle the shot. The SLT was analyzed to ensure that it would not jeopardize worker safety during operation. The results from the static analysis of the SLT under deadweight and vibrator operating loads show that the stresses in the SLT are below code allowables. The results from the modal analysis show that the natural frequencies of the SLT are far below the operating frequencies of the vibrators, provided the SLT is mounted on pneumatic tires. The SLT was also analyzed for wind, seismic, deadweight, and moving/transporting loads. Analysis of the SLT is in accordance with SDC-4.1 for safety class 3 structures (DOE-RL 1993) and the American Institute of Steel Construction (AISC) Manual of Steel Construction (AISC 1989).

    Funds were requested to continue our program in meteoritic sulfur isotopic analysis. We have recently detected a potential nucleosynthetic sulfur isotopic anomaly. We will search for potential carriers. The documentation of bulk systematics and the possible relation to nebular chemistry and oxygen isotopes will be explored. Analytical techniques for delta(sup 33), delta(sup 34)S, delta(sup 36)S isotopic analysis were improved. Analysis of sub milligram samples is now possible. A possible relation between sulfur isotopes and oxygen was detected, with similar group systematics noted, particularly in the case of aubrites, ureilites and entstatite chondrites. A possible nucleosynthetic excess S-33 has been noted in bulk ureilites and an oldhamite separate from Norton County. High energy proton (approximately 1 GeV) bombardments of iron foils were done to experimentally determine S-33, S-36 spallogenic yields for quantitation of isotopic measurements in iron meteorites. Techniques for measurement of mineral separates were perfected and an analysis program initiated. The systematic behavior of bulk sulfur isotopes will continue to be explored.

  2. Is risk analysis scientific?

    PubMed

    Hansson, Sven Ove; Aven, Terje

    2014-07-01

    This article discusses to what extent risk analysis is scientific in view of a set of commonly used definitions and criteria. We consider scientific knowledge to be characterized by its subject matter, its success in developing the best available knowledge in its fields of study, and the epistemic norms and values that guide scientific investigations. We proceed to assess the field of risk analysis according to these criteria. For this purpose, we use a model for risk analysis in which science is used as a base for decision making on risks, which covers the five elements evidence, knowledge base, broad risk evaluation, managerial review and judgment, and the decision; and that relates these elements to the domains experts and decisionmakers, and to the domains fact-based or value-based. We conclude that risk analysis is a scientific field of study, when understood as consisting primarily of (i) knowledge about risk-related phenomena, processes, events, etc., and (ii) concepts, theories, frameworks, approaches, principles, methods and models to understand, assess, characterize, communicate, and manage risk, in general and for specific applications (the instrumental part).

  13. Introduction to Food Analysis

    NASA Astrophysics Data System (ADS)

    Nielsen, S. Suzanne

    Investigations in food science and technology, whether by the food industry, governmental agencies, or universities, often require determination of food composition and characteristics. Trends and demands of consumers, the food industry, and national and international regulations challenge food scientists as they work to monitor food composition and to ensure the quality and safety of the food supply. All food products require analysis as part of a quality management program throughout the development process (including raw ingredients), through production, and after a product is in the market. In addition, analysis is done of problem samples and competitor products. The characteristics of foods (i.e., chemical composition, physical properties, sensory properties) are used to answer specific questions for regulatory purposes and typical quality control. The nature of the sample and the specific reason for the analysis commonly dictate the choice of analytical methods. Speed, precision, accuracy, and ruggedness often are key factors in this choice. Validation of the method for the specific food matrix being analyzed is necessary to ensure usefulness of the method. Making an appropriate choice of the analytical technique for a specific application requires a good knowledge of the various techniques (Fig. 1.1). For example, your choice of method to determine the salt content of potato chips would be different if it is for nutrition labeling than for quality control. The success of any analytical method relies on the proper selection and preparation of the food sample, carefully performing the analysis, and doing the appropriate calculations and interpretation of the data. Methods of analysis developed and endorsed by several nonprofit scientific organizations allow for standardized comparisons of results between different laboratories and for evaluation of less standard procedures. Such official methods are critical in the analysis of foods, to ensure that they meet the legal requirements established by governmental agencies. Government regulations and international standards most relevant to the analysis of foods are mentioned here but covered in more detail in Chap. 2, and nutrition labeling regulations in the USA are covered in Chap. 3. Internet addresses for many of the organizations and government agencies discussed are given at the end of this chapter.

  14. Drift Degradation Analysis

    Dwayne C. Kicker

    A statistical description of the probable block sizes formed by fractures around the emplacement drifts has been developed for each of the lithologic units of the repository host horizon. A range of drift orientations with the drift azimuth varied in 15{sup o} increments has been considered in the static analysis. For the quasi-static seismic analysis, and the time-dependent and thermal effects analysis, two drift orientations have been considered: a drift azimuth of 105{sup o} and the current emplacement drift azimuth of 75{sup o}. The change in drift profile resulting from progressive deterioration of the emplacement drifts has been assessed both with and without backfill. Drift profiles have been determined for four different time increments, including static (i.e., upon excavation), 200 years, 2,000 years, and 10,000 years. The effect of seismic events on rock fall has been analyzed. Block size distributions and drift profiles have been determined for three seismic levels, including a 1,000-year event, a 5,000-year event, and a 10,000-year event. Data developed in this modeling and analysis activity have been entered into the TDMS (DTN: MO0109RDDAAMRR.003). The following conclusions have resulted from this drift degradation analysis: (1) The available fracture data are suitable for supporting a detailed key block analysis of the repository host horizon rock mass. The available data from the north-south Main Drift and the east-west Cross Drift provide a sufficient representative fracture sample of the repository emplacement drift horizon. However, the Tptpln fracture data are only available from a relatively small section of the Cross Drift, resulting in a smaller fracture sample size compared to the other lithologic units. This results in a lower degree of confidence that the key block data based on the Tptpln data set is actually representative of the overall Tptpln key block population. (2) The seismic effect on the rock fall size distribution for all events analyzed is relatively minor. (3) The analysis of thermal and time-dependent effects on rock fall in this study is based on a reduction in the joint cohesion. Joint cohesion has been conservatively reduced from a laboratory test value of 0.86 MPa to a value of 0.01 MPa after 10,000 years. The results from this analysis indicate that time-dependent and thermal effects have a minor impact on rock fall. (4) Both the 75 percentile and the worst-case drift degradation profiles have been provided in this analysis for the current emplacement drift azimuth of approximately 75{sup o}. Most of the emplacement drift openings were not affected by rock fall. For the current emplacement drift alignment, the highest percentage of drift affected by rock fall was 8% in the Tptpmn unit. The Tptpmn unit produced the highest frequency of key blocks per kilometer compared to the other lithologic units (Tables 26 and 41). (5) This key block analysis has shown that the current drift alignment is relatively favorable in terms of reducing the potential maximum size rock block compared to most drift orientations.

    The current focal point of the nuclear physics program at PNNL is the MAJORANA DEMONSTRATOR, and the follow-on Tonne-Scale experiment, a large array of ultra-low background high-purity germanium detectors, enriched in 76Ge, designed to search for zero-neutrino double-beta decay (0???). This experiment requires the use of germanium isotopically enriched in 76Ge. The MAJORANA DEMONSTRATOR is a DOE and NSF funded project with a major science impact. The DEMONSTRATOR will utilize 76Ge from Russia, but for the Tonne-Scale experiment it is hoped that an alternate technology, possibly one under development at Nonlinear Ion Dynamics (NID), will be a viable, US-based, lower-cost source of separated material. Samples of separated material from NID require analysis to determine the isotopic distribution and impurities. DOE is funding NID through an SBIR grant for development of their separation technology for application to the Tonne-Scale experiment. The Environmental Molecular Sciences facility (EMSL), a DOE user facility at PNNL, has the required mass spectroscopy instruments for making isotopic measurements that are essential to the quality assurance for the MAJORANA DEMONSTRATOR and for the development of the future separation technology required for the Tonne-Scale experiment. A sample of isotopically separated copper was provided by NID to PNNL in January 2011 for isotopic analysis as a test of the NID technology. The results of that analysis are reported here. A second sample of isotopically separated copper was provided by NID to PNNL in August 2011 for isotopic analysis as a test of the NID technology. The results of that analysis are also reported here.

  16. Complementing Gender Analysis Methods.

    PubMed

    Kumar, Anant

    2016-01-01

    The existing gender analysis frameworks start with a premise that men and women are equal and should be treated equally. These frameworks give emphasis on equal distribution of resources between men and women and believe that this will bring equality which is not always true. Despite equal distribution of resources, women tend to suffer and experience discrimination in many areas of their lives such as the power to control resources within social relationships, and the need for emotional security and reproductive rights within interpersonal relationships. These frameworks believe that patriarchy as an institution plays an important role in women's oppression, exploitation, and it is a barrier in their empowerment and rights. Thus, some think that by ensuring equal distribution of resources and empowering women economically, institutions like patriarchy can be challenged. These frameworks are based on proposed equality principle which puts men and women in competing roles. Thus, the real equality will never be achieved. Contrary to the existing gender analysis frameworks, the Complementing Gender Analysis framework proposed by the author provides a new approach toward gender analysis which not only recognizes the role of economic empowerment and equal distribution of resources but suggests to incorporate the concept and role of social capital, equity, and doing gender in gender analysis which is based on perceived equity principle, putting men and women in complementing roles that may lead to equality. In this article the author reviews the mainstream gender theories in development from the viewpoint of the complementary roles of gender. This alternative view is argued based on existing literature and an anecdote of observations made by the author. While criticizing the equality theory, the author offers equity theory in resolving the gender conflict by using the concept of social and psychological capital. PMID:25941756

  17. Physics analysis tools

    Kunz, P.F.

    1991-04-01

    There are many tools used in analysis in High Energy Physics (HEP). They range from low level tools such as a programming language to high level such as a detector simulation package. This paper will discuss some aspects of these tools that are directly associated with the process of analyzing HEP data. Physics analysis tools cover the whole range from the simulation of the interactions of particles to the display and fitting of statistical data. For purposes of this paper, the stages of analysis is broken down to five main stages. The categories are also classified as areas of generation, reconstruction, and analysis. Different detector groups use different terms for these stages thus it is useful to define what is meant by them in this paper. The particle generation stage is a simulation of the initial interaction, the production of particles, and the decay of the short lived particles. The detector simulation stage simulates the behavior of an event in a detector. The track reconstruction stage does pattern recognition on the measured or simulated space points, calorimeter information, etc., and reconstructs track segments of the original event. The event reconstruction stage takes the reconstructed tracks, along with particle identification information and assigns masses to produce 4-vectors. Finally the display and fit stage displays statistical data accumulated in the preceding stages in the form of histograms, scatter plots, etc. The remainder of this paper will consider what analysis tools are available today, and what one might expect in the future. In each stage, the integration of the tools with other stages and the portability of the tool will be analyzed.

    GLORIA stands for “GLObal Robotic-telescopes Intelligent Array”. GLORIA will be the first free and open-access network of robotic telescopes of the world. It will be a Web 2.0 environment where users can do research in astronomy by observing with robotic telescopes, and/or analyzing data that other users have acquired with GLORIA, or from other free access databases, like the European Virtual Observatory. GLORIA project will define free standards, protocols and methodology for controlling Robotic Telescopes and related instrumentation, for conducting so called on-line experiments by scheduling observations in the telescope network, and for conducting so-called off-line experiments based on the analysis of astronomical meta-data produced by GLORIA or other databases. Luiza analysis framework for GLORIA was based on the Marlin package developed for the International Linear Collider (ILC), data analysis. HEP experiments have to deal with enormous amounts of data and distributed data analysis is a must, so the Marlin framework concept seemed to be well suited for GLORIA needs. The idea (and large parts of code) taken from Marlin is that every computing task is implemented as a processor (module) that analyzes the data stored in an internal data structure and created additional output is also added to that collection. The advantage of such a modular approach is to keep things as simple as possible. Every single step of the full analysis chain that goes eg. from raw images to light curves can be processed separately and the output of each step is still self consistent and can be fed in to the next step without any manipulation.

    Ghezzi, Giacomo; Gall, Harald C.

    Throughout the years software engineers have come up with a myriad of specialized tools and techniques that focus on a certain type of software analysissoftware analysis such as source code analysis, co-change analysis or bug prediction. However, easy and straight forward synergies between these analyses and tools rarely exist because of their stand-alone nature, their platform dependence, their different input and output formats and the variety of data to analyze. As a consequence, distributed and collaborative software analysiscollaborative software analysis scenarios and in particular interoperability are severely limited. We describe a distributed and collaborative software analysis platform that allows for a seamless interoperability of software analysis tools across platform, geographical and organizational boundaries. We realize software analysis tools as services that can be accessed and composed over the Internet. These distributed analysis services shall be widely accessible in our incrementally augmented Software Analysis Broker software analysis broker where organizations and tool providers can register and share their tools. To allow (semi-) automatic use and composition of these tools, they are classified and mapped into a software analysis taxonomy and adhere to specific meta-models and ontologiesontologies for their category of analysis.
