INTRODUCTION: MAKING A CASE FOR DISCOURSEANALYSIS IN FOREIGN LANGUAGE TEACHER EDUCATION The concept of heteroglossia is extremely interesting to me. I recently gave a paper in which I discussed Ingeborg Bachmann's Malina and asserted that the main character had basically two voices: one masculine, one feminine. I found it fascinating after reading the chapter in Fowler  to think
In this article I will use an example of current adult education practice, the Glory and Dismay Football Literacies Programme (GDFLP) to appraise the value of critical discourseanalysis (CDA) for adult learners, both individually and collectively, and for adult education practitioners with an interest in developing critical literacy skills. The
Over the past two decades, critical discourseanalysis has emerged as a major new multidisciplinary approach to the study of texts and contexts in the public sphere. Developed in Europe, CDA has lately become increasingly popular in North America, where it is proving especially congenial to new directions in rhetoric and composition. This essay

Research studies using discourseanalysis 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 discourseanalysis validated? This paper proposes transdisciplinary convergence as a way to validate discourseanalysis approaches to research. The argument is made that discourseanalysis 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.

Evidence generated within the emotional disclosure paradigm (EDP) suggests that talking or writing about emotional experiences produces health benefits, but recent meta-analyses have questioned its efficacy. Studies within the EDP typically rely upon a unidimensional and relatively unsophisticated notion of emotional inhibition, and tend to use quantitative forms of content analysis to identify associations between percentages of word types and positive or negative health outcomes. In this article, we use a case study to show how a qualitative discourseanalysis has the potential to identify more of the complexity linking the disclosure practices and styles that may be associated with emotional inhibition. This may illuminate the apparent lack of evidence for efficacy of the EDP by enabling more comprehensive theorisations of the variations within it. PMID:21678182
Combining linguistics and composition studies, this paper (part 1 of a two-part article) proposes a model for the analysis of information management and cohesion in written discourse.

In undertaking a critical discourseanalysis of the professed aims and objectives of one of the most influential curricula in the teaching of thinking, this article foregrounds issues of power and ideology latent in curricular discourses of rationality. Specifically, it documents the subtle but powerful ways in which political and class
Critical DiscourseAnalysis (CDA) sees discourse as a form of "social practice", in which language use is seen at the same time as socially influenced and influential. Another characteristic of CDA is that it is engaged and committed; it intervenes in social practice and attempts to reveal connections between language use, power, and ideology. The
Four group summary papers from an Australian national workshop on discourseanalysis discuss verbal and written discourse and the classroom. Papers reflect the four workshop discussion groups of casual conversation, classroom discourse, expository discourse, and literary narrative. They include: "On Casual Conversation" (M. A. K.

Understanding the ways in which teachers make sense of what they do and why is critical to a broader understanding of pedagogy. Historically, teachers have been understood through the thematic and content analysis of their beliefs or philosophies. In this paper, we argue that discourseanalysis (DA) involves a much finer-grained analysis of the
Discourse has always been at the heart of teaching. In more recent years, the mathematics education community has also turned its attention towards understanding the role of discourse in mathematics teaching and learning. Using earlier classifications of discourse, in this paper, we looked at three types of classrooms: classrooms that engage in
A brief overview of discourseanalysis is presented, followed by: (1) a description of cross-cultural discourseanalysis; (2) an explanation of how cross-cultural discourseanalysis applies to language for special purposes (LSP) in general; and (3) a discussion of selected areas for ongoing and future research areas.

Critical DiscourseAnalysis (CDA) has reached a certain degree of canonical status, as it is widely used and applied as a research and analytic tool.

The article argues that there is no such thing as Critical DiscourseAnalysis (CDA) in the sense of a method of political or ideological critique based on the application of conventional linguistic constructs. All of us, as language users and makers, are continuously engaged in the critical examination of and response to communication in our everyday lives. The article argues
In this article, I question the micro-macro separation in discourseanalysis, the separation of personal and institutional discourses. I apply a mostly macroanalytic perspective (critical discourseanalysis [CDA]) to inform a predominantly microanalytic perspective (analysis of conversational narratives) and vice versa. In the combination of these
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 Discourseanalysis. 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.

The aim of this study was to describe and understand the relationship of swimmers' practice intensity and alexithymia features in discourse. This study investigated psychological processes in two groups of male swimmers training at different intensities. The first group was composed of 10 Expert amateurs (M age = 19.5 yr., SD = 1.9), who were competing at the national or international level and trained 22 hours per week. The second group was composed of 10 Amateur swimmers (M age = 20.5 yr., SD = 1.4), who competed at the regional level and trained 6 hours per week. The discourse of swimmers was analysed using the ALCESTE (Analyse de Lexèmes Coocurents dans les Enoncés Simples d'un Texte) method of discourseanalysis. Discourseanalysis was performed on speech samples produced by swimmers. All the swimmers showed alexithymic verbal behaviour as regards both the means of expression used and the feelings and emotions expressed. This lack of articulateness was more pronounced in the Expert than in the Amateur group. The difference of alexithymic features in correlation with the intensity of sport practice raises the question of the health benefits of intense sports practice and the need for psychological assessment of athletes.

Discourseanalysis 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 discourseanalysis 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 discourseanalysis 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 discourseanalysis in nursing research. PMID:23679133
This article begins with a review of the place of Hugh Mehans Learning Lessons in the development of the naturalistic study of classroom discourse studies, and especially the sequential analysis of naturally occurring classroom discourse. It then turns to the emergence of an alternative program for classroom discourse studies, in the particulars of critical discourseanalysis. There we find a

A number of writers have drawn attention to the increasing importance of language in social life in "new times" and Fairclough has referred to "discourse driven" social change. These conditions have led to an increase in the use of various forms of discourseanalysis in policy analysis. This paper explores the possibilities of using Critical
One aspect of Critical DiscourseAnalysis (CDA) involves examining how metaphors in texts, particularly hard news texts (reports of very recent conflicts, crimes, etc.), imply certain values. The usual theoretical basis for such analysis is Lakoff and Johnson (1980). My article shows problems with transplanting Lakoff and Johnson's discourse-level

Text analysis traditions in France and the United States include discourseanalysis, critical linguistics, French functional linguistics, Bakhtinian dialogics, and "generous reading." These frames have not been used, however, in cross-cultural analysis of university student writing. The author presents a study of 250 student texts from French and
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 discourseanalysis 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.
This article supports critical, social justice oriented science education research by providing a theoretical and methodological basis for examining how subjectivities may be constituted through discourses found in science education texts. Such research explores how discourses orient teachers and students to the world, others, and themselves, as
This article reports a critical discourseanalysis of a series of newspaper advertisements advocating `ex-gay' ministries and `reparative therapy' for homosexuality interventions designed to `treat' homosexuality through prayer or psychoanalysis. These ads, part of an effort to make `ex-gay' discourse more central to the public communication strategies of conservative, anti-gay political groups, feature both narrative and statistical arguments that

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.

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 discourseanalysis 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 DiscourseAnalysis (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.

Background Health service policy in the United Kingdom emphasises the importance of self-care by patients with chronic conditions. Written information for patients about their condition is seen as an important aid to help patients look after themselves. From a discourseanalysis perspective written texts such as patient information leaflets do not simply describe the reality of a medical condition and its management but by drawing on some sorts of knowledge and evidence rather than others help construct the reality of that condition. This study explored patient information leaflets on osteoarthritis (OA) to see how OA was constructed and to consider the implications for self-care. Methods Systematic and repeated readings of six patient information leaflets on osteoarthritis to look for similarities and differences across leaflets, contradictions within leaflets and the resources called on to make claims about the nature of OA and its management. Results Biomedical discourse of OA as a joint disease dominated. Only one leaflet included an illness discourse albeit limited, and was also the only one to feature patient experiences of living with OA. The leaflets had different views on the causes of OA including the role of lifestyle and ageing. Most emphasised patient responsibility for preventing the progression of OA. Advice about changing behaviour such as diet and exercise was not grounded in lived experience. There were inconsistent messages about using painkillers, exercise and the need to involve professionals when making changes to lifestyle. Conclusion The nature of the discourse impacted on how OA and the respective roles of patients and professionals were depicted. Limited discourse on illness meant that the complexity of living with OA and its consequences was underestimated. Written information needs to shift from joint biology to helping patients live with osteoarthritis. Written information should incorporate patient experience and value it alongside biomedical knowledge. PMID:17428315
Mental Health nursing exists as a discipline in the UK within the wider contemporary health care establishment. Throughout its history it has attempted to define itself in ways that differentiate mental health nursing practice from other health care professions and fields of nursing. However, it is not surprising in this climate of contemporary healthcare for individual professional identities to become 'lost' in the melange of interdisciplinary practice. This research presents a discourseanalysis of individual mental health nurses' rhetorical constructions of their professional role(s) as they emerge in their talk with each other in focus group discussions. In particular, the focus in this paper is their discursive repertoires related to the historical legacy of mental health nursing and how this sits with what they consider to be a 'custodial and controlling' element of their role. The particular discourse analytic approach adopted in this study illustrates how individuals use language in a particular way to make justifications and explanations of mental health nursing identities. This analytic approach is ensconced within the domain of social psychology and lies at the interface of ethno-methodology and conversation analysis. It is concerned with structural units of discourse, beyond the level of the sentence, that emerge as the nurse participants engage in talking about their practice (Potter and Wetherell, 1987 p.53).

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 individuals 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.

Whilst the experience of a patient suicide is likely to have a significant impact upon the nurses who had been providing care, little work has actually explored this experience in any depth. In this article we explore how two psychiatric nurses construct and orient to accountability when talking of their experiences of a patient suicide. Discourseanalysis was used to explore particular phases that the nurses oriented to in their accounts: scene setting; risk assessment; attributing for the suicide. Findings highlight the different, sometimes contradictory, ways the nurses attended to interactional concerns relating to implicit accountability and potential inferences of blame. Analysis of the nurses talk can make a valuable contribution to understanding the nature and the impact of accountability in a mental health setting and so help nurses and other professionals gain an insight into their practice. The results from this study suggest that as a consequence of internalising fundamentally unrealisable expectations regarding suicide prevention, nurses can hold themselves to blame raising significant concerns around their needs in terms of support, which may not be recognised. This paper also makes a valuable contribution to our methodological understanding and the value of using discourseanalysis in this setting. PMID:20305746

This thesis is about Sociobiology, especially human sociobiological discourse, and its emergence as a paradigm especially through the formulations of E. O. Wilson. It asks two distinct and related questions. The first question asks why and how has the general project of Wilsonian or determinist human sociobiology has maintained its appeal and continued to garner popularity and support despite the many cogent and detailed critiques. The second question, covered in part two of this thesis, asks how the sociobiological controversy is presented in three Biology textbooks. Part one of this work examines the development of human sociobiology and its related disciplines and the debates that have arisen around this paradigm. It chronicles how this Wilsonian human sociobiological discourse constructs its legitimacy, the major issues critics have raised and recent developments in human sociobiology and related fields. It also suggests modified epistemological positions and avenues of critique. As such, this work utilizes theory developed within utilizes theory developed within science studies, hegemony studies, discourse theory, textual analysis, and science education. Part Two examines three textbooks used in Ontario Academic Courses (OAC's) in Biology in high school in grade thirteen in Ontario. These texts are similar if not identical to textbooks used in introductory biology courses in universities in North America. This textual analysis, examines how the textbooks portray sociobiology and the related fields of Genetics, Evolutionary theory and the Nature of Science itself. This analysis provides a way both to gauge the influence of Wilsonian human and non-human sociobiological discourse and to gauge the ways in which this controversial issue is handled by the texts. This analysis finds that all three textbooks fail to use sociobiology as an example of a scientific controversy to engage students in a discussion of this topic. They also fail to engage students in any of the collateral controversial issues in genetics, evolutionary theory and the nature of science itself. This work also borrows from the constructivist, Science-Technology-Society-Environment (STS-E), and Nature of Science movements within science education and begins to make recommendations for teachers and textbook authors regarding the teaching and presentations of sociobiology and the nature of science debates.
This study explored the discourse of mental illness contained within two UK newspapers over a 15-year period, excluding those stories that mentioned any reference to a diagnosis. Using frame analysis, a form of discourseanalysis, ten distinct frames were identified and classified into "stories." These ten stories were categorized as: foreign, legal, drug, feature, trauma, tragedy, community care tragedy, social policy, inquiry report, and sports/celebrity stories. Each frame is described and the potential influence of such frames on both social policy and nursing practice is discussed. PMID:17957551
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 discourseanalysis. 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.

This paper addresses how families' roles and responsibility for care are constructed within home health (in contrast to the responsibility of home health). A discourseanalysis informed by a critical theoretical approach was used to analyze qualitative interviews with 13 home health managers and clinical leaders in British Columbia, alongside home care documents. When referring to family involvement, there was an emphasis on the importance of supporting a client's choice to stay at home. Government and agency documents describe family members as primary providers, with home health having a supplementary role. Agencies seek to avoid "substituting" for family care. Family responsibility is characterized as having both moral and structural value. Nonetheless, some participants advocated flexibility and recognized potential caregiving challenges. Data provide examples of how agency expectations are communicated to clients and families and become embedded within practice and policy. Findings are viewed within the broader organizational context as representing the "responsibilization" of support. PMID:24289942
In this paper, we present and apply a multi-level method for discourseanalysis in science classrooms. This method is based on the structure of human activity (activity, actions, and operations) and it was applied to study a pre-service physics teacher methods course. We argue that such an approach, based on a cultural psychological perspective,

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.

In this article, we examine a set of 26 children's books on HIV/AIDS published between 1989-1999 to identify the ways in which these texts construct HIV/AIDS and people living with HIV/AIDS. We explore how this marginalized group is depicted in these books, and how well-meaning teachers may in fact be reproducing dominant discourses about HIV/AIDS
International studies on the death of elderly nursing home residents show the complexity in the understanding of the professionals who care for the dying. The aim of this study is to explore the discourses about professional caregivers caring for those dying in Denmark in the last decade. A discourseanalysis inspired by Foucault was constructed. The material consists of different source documents: research articles, newspaper articles, theses, books, websites - 35 sources in total. There are constructed six positions of speech, five discourses and three themes: (1) 'the work of the professional caregivers - a complex low-status work'; (2) 'the education of the professionals - the way to ensure a good death or possessing the right qualifications' and (3) 'the vulnerable professionals'. The study concludes that an economical/political discourse is dominating and sets up the frames within which the professionals care for dying residents, although the medical, the social/critical and the religious discourses attempt to speak against it. All positions articulate that the professional caregivers' job has a low status and that it is not possible to provide an optimal care due to lack of time, resources and education. Psychical or mental demands make the professionals vulnerable. The meaning of optimal care varies according to the positions of speech. PMID:23336738
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.

Objective The purpose of this study is to conduct an analysis of actual communicative behaviors, including nonverbal ones, between physicians and patients in rehabilitation. Design Sixteen videotaped physicianpatient interactions in a rehabilitation center in Korea were transcribed. And three coders placed utterances in transcripts into categories while watching the videotapes. Results Consistent with results of previous studies, patient active communicative behaviors varied considerably depending on individual patients. The findings revealed that, on average, patients' active communicative behaviors were less than 9% of patients' total utterances. In particular, almost half of the patients (N = 7) did not even ask one single question. The results also showed that physicians' empathic communicative acts averaged less than 3% of physicians' total utterances. In addition, among physicians' nonverbal behaviors, eye-contact showed significant correlation with physician empathic listening and supportive talks. Conclusions The findings of this study indicated a considerable lack of empathic communicative behaviors of physicians in Korea. This might have led to infrequent use of active communicative behaviors by patients. In addition, the importance of physician's partnership for enhancement of active communicative behaviors of patients was demonstrated. To better serve patients, physicians who wish to improve their communication should first identify components of their empathic communicative behaviors that need improvement and then attempt to refine their skills.

This paper reports a discourseanalysis of the language doctors used as they talked about and engaged in patient handoffs between the emergency department (ED) and various inpatient services at one highly specialized academic tertiary teaching and referral hospital in the Midwest United States. Although interest in handoff improvement has grown considerably in recent years, progress has been hampered, perhaps in part, because of a widely used but limiting conceptual model of handoff as an information transmission. The purpose of the study reported here is to analyze the way doctors make sense of handoff interactions, including uncovering the interpretive frames they use, in order to provide empirical findings to expand conceptual models of handoff. All data reported were drawn from a two-year ethnographic study (2009-2011) and include semi-structured interviews (n = 48), non-participant observations (349 h), and recorded telephone handoff conversations (n = 48). A total of eighty-six individuals participated, including resident and attending doctors from the ED, internal medicine and surgical services, as well as hospital administrators. Findings are organized around four metaphors doctors used: sales, sports and games, packaging, and teamwork. Each metaphor, in turn, reveals an underlying interpretive frame that appears to be influenced by organizational and social structures and to shape the possibilities for action that doctors perceive. The four underlying interpretive frames are: handoff as persuasion, handoff as competition, handoff as expectation matching, and handoff as collaboration. Taken together, these interpretive frames highlight the complex, socially interactive nature of handoff and provide an empirical basis for grounding and enriching the conceptual model of handoff that guides research and practice improvement efforts.

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

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

Students' views of the nature of scientific knowledge have been recognized as an important component of science learning environments. In this study, we analyze an extensive data base consisting of 23 students' written and oral discourse about ontology, epistemology, and sociology of scientific knowledge collected over a 15-month period in the context of two consecutive junior- and senior-level physics courses. Over a 2-month period at the beginning of the second year, students read, reflected on, and talked about a text which discusses epistemology in the context of physics. Our study shows that students drew on nine types of discursive resources to support their ontological, epistemological, and sociological claims. Toward the end of the study, the range and number of supportive statements had increased. Simultaneously, few students changed their ontological and sociological claims, but a considerable number changed their epistemological claims. Two case studies illustrate the development of student discourse in the course of the study.

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

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 discourseanalysis 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.
This dissertation examined linguistic and pragmatic characteristics of written discourse of North Korean second language speakers of English comparing it with that of North American native speakers of English by analyzing linguistic features used in the two sets of texts and their discursive functions based on Biber's (1995) and Hinkel's
Research on the acquisition of Spanish's two copulas, "ser" and "estar," provides an understanding of the interaction among syntax, semantics, pragmatics, morphology, and vocabulary during development (e.g., Geeslin, 2003a, 2003b; Gunterman, 1992; Ryan & Lafford, 1992). Recent research suggests that linguistic features in the surrounding discourse

The issue of immigration proved to be a crucially important flashpoint for all three parties in the 2010 British General Election. In this paper, we focus on a citizen-centred perspective on the 2010 British General Election by analysing the views of the electorate on this pivotal issue in the as blogosphere. Using thematic and discursive analysis, we examine how voters
The leading question of this Forest Policy and Economics special issue is whether, how and to what extent forest governance processes can be better understood by means of discourseanalysis and the science-policy interface. This article focuses on discourses only, but it does so from an institutional perspective. The reasons to advocate this so-called discursive-institutional approach are threefold: (1) to
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 Pennings 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.

Walker (1996) presents a cache model of the operation of attention in the processing of discourse as an alternative to the focus space stack that was proposed previously by Grosz and Sidner (Grosz 1977a; Grosz and Sidner 1986). In this squib, we present a critical analysis of the cache model and of Walker's supporting evidence from anaphora in discourses with
Current scholarship on language and communication has largely been culturally monological rather than dialogical and diversified. In this paper, I respond to this sorry state by arguing for the reconstruction of Eastern paradigms in favour of multiculturalism in discourse research. To that end, I first critique the ethnocentrism of DiscourseAnalysis, then point to the cultural realities of the Eastern

Drawing on an activity theory framework that integrates the analysis of these seemingly contradictory discourses with a study of teacher educators' practical
The present study examined the discourses of homosexuality in the police, using the discourse analytic method developed by Potter and Wetherell (1987). The study asked how police officers constructed gay men using their discourses and why gay men should or should not be employed by the police. Eight police officers were interviewed. Analysis revealed officers drew on three distinct discourses to construct gay men. The effeminate discourse associated homosexuals with effeminate behaviors. The deviant discourse associated homosexuals with behaviors that are morally and legally prescribed, and the discourse of conditional acceptance was used by officers to positively present, while voicing reservations about homosexuals. These discourses formed the linguistic resources officers used to construct types of homosexuals that were subsequently rejected as potential police officers. Several arguments were used to justify the conclusion that homosexuals were unsuited to the police. These related to the internal and external pressures impinging on the department with regard to the employment of homosexuals. The implications of the discourses are discussed with reference to gay men, the police, and the ideologies of heterosexism and gender. PMID:8905529
Argues that post-structuralist discourseanalysis has a strong contribution to make to feminist and educational research, examining how the use of feminist post-structuralist discourseanalysis (FPDA) can be tricky.

In this article, we examine the oral and written discourse processes in a high school physics class and how these discourse processes are related to sociocultural practices in scientific communities. Our theoretical framework is based on sociological and anthropological studies of scientific communities and ethnographies of classroom life. We review the use of discourseanalysis as a methodological orientation in science education and provide a logic-of-inquiry framing how we used discourseanalysis in our ethnographic research. Our ethnographic analysis showed that, through students' participation in creating scientific papers on the physics of sound, their appropriation of scientific discourse was related to the framing activities of the teachers and the social practices established over time in the classroom. Our textual analysis of the student papers focused on how they used evidence to make claims. We explore the lessons learned from participating in the classroom of these students.
The issues in the interpretation of discriminant analyses presented are restricted to the typical uses of discriminant analysis by behavioral science researchers. Because behavioral researchers use computer programs packages, the issues discussed deal with information obtainable from the package discriminant analysis programs. The following issues
Analysis of the metabolome with coverage of all of the possibly detectable components in the sample, rather than analysis of each individual metabolite at a given time, can be accomplished by metabolic analysis. Targeted and/or nontargeted approaches are applied as needed for particular experiments. Monitoring hundreds or more metabolites at a given time requires high-throughput and high-end techniques that enable screening for relative changes in, rather than absolute concentrations of, compounds within a wide dynamic range. Most of the analytical techniques useful for these purposes use GC or HPLC/UPLC separation modules coupled to a fast and accurate mass spectrometer. GC separations require chemical modification (derivatization) before analysis, and work efficiently for the small molecules. HPLC separations are better suited for the analysis of labile and nonvolatile polar and nonpolar compounds in their native form. Direct infusion and NMR-based techniques are mostly used for fingerprinting and snap phenotyping, where applicable. Discovery and validation of metabolic biomarkers are exciting and promising opportunities offered by metabolic analysis applied to biological and biomedical experiments. We have demonstrated that GC-TOF-MS, HPLC/UPLC-RP-MS and HILIC-LC-MS techniques used for metabolic analysis offer sufficient metabolome mapping providing researchers with confident data for subsequent multivariate analysis and data mining.

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.
Multivariable analysis is a challenging subject for clinicians, whether they are novice researchers or trained practitioners. Most basic biostatistics books do not cover multivariable analysis, while existing multivariable analysis books are dense with mathematical formulas. Multivariable Analysis: A Practical Guide for Clinicians steps aside from mathematics and offers conceptual explanations. Dr. Mitchell Katz follows a nonthreatening, question-and-answer approach to explain how to perform and interpret multivariable analyses. He begins by explaining why clinicians should do multivariable analyses and then guides the reader through topics such as how to choose which type of multivariable method to perform, how to deal with missing data, and how to validate multivariable models. The book is loaded with useful tips, tables, figures, and references. Examples from the medical literature demonstrate several real-world applications and uses of multivariable analysis. This book will prove to be an indispensable guide for medical students, residents, and practicing physicians.

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.

After an 800-foot-tall offshore oil recovery platform collapsed, the engineers at Engineering Dynamics, Inc., Kenner, LA, needed to learn the cause of the collapse, and analyze the proposed repairs. They used STAGSC-1, a NASA structural analysis program with geometric and nonlinear buckling analysis. The program allowed engineers to determine the deflected and buckling shapes of the structural elements. They could then view the proposed repairs under the pressure that caused the original collapse.
The University of Georgia used NASTRAN, a COSMIC program that predicts how a design will stand up under stress, to develop a model for monitoring the transient cooling of vegetables. The winter use of passive solar heating for poultry houses is also under investigation by the Agricultural Engineering Dept. Another study involved thermal analysis of black and green nursery containers. The use of NASTRAN has encouraged student appreciation of sophisticated computer analysis.

In combination with other tests these analyses can separate synthetic from natural gems.
We present "Implicit Action", a discourse management tool, through a qualitative video analysis of a Florida International University Modeling Instruction Introductory Physics I class. Implicit Action in Modeling Instruction is where instructors deliberately create intellectual space in which students ideally see value and need for the construction of new classroom norms and tools that are productive in developing a learning community. This space is created by the implications expressed through the instructors' deliberate actions. Discourse Management is a technique to moderate student discourse in Modeling Instruction classes at the university level that was initially described by Desbien. Implicit Action is one of 9 Modeling Discourse Management tools that we have identified. By means of qualitative analysis we illustrate the effectiveness of Implicit Action in implementing the Modeling Theory of Instruction.

Background In medical literature, several principles that define good consultations have been outlined. These principles tend to be prescriptive in nature, overlooking the complexity of general practitioners (GPs) perspectives of everyday practice. Focusing on perspectives might be particularly relevant, since they may affect decisions and actions. Therefore, the present study adopts a bottom-up approach, analyzing GPs narratives about good and bad consultations. We aimed at describing the range of discourses GPs use in relating on their practice. Methods Semi-structured interviews were conducted with 19 Belgian GPs. By means of a qualitative analysis, the authors mapped patterns in the interview narratives and described the range of different discourses. Results Four discourses were identified: a biomedically-centered discourse, a communication-focused discourse, a problem-solving discourse and a satisfaction-oriented discourse. Each discourse was further specified in terms of predominant themes, problems the GPs prefer to deal with and inherent difficulties. Although most participants used elements from all four discourses, the majority of the GPs relied on an individual set of predominant discourses and focused on a limited number of themes. Conclusion This study clearly indicates that there is no uniform way in which GPs perceive clinical practice. Each of the participants used a subtle mix of different criteria to define good and bad medical consultations. Some discourse elements appear to be rooted in medical literature, whereas others are of a more personal nature. By focusing on the limitations of each discourse, this study can shed new light on some of the difficulties GPs encounter in their daily practice: being confronted with specific problems might be an effect of adhering to a specific discourse. The typification of different discourses on consultations may function as a framework to help GPs reflect on how they perceive their practice, and help them manage some of the challenges met in daily practice.

For many chemistry and physics students, some of the most frustrating problems involve dimensional analysis. This is a very important concept that is more related to mathematics and equation consistency than the sciences. A dimensional analysis tutorial is offered at the physics department's Web site of the University of Guelph. It is an excellent guide that helps students understand the five dimensions of physical quantities and how to work with units to achieve correct results. There are seven quizzes and a final post-test that assess the student's grasp of the topic, with answers given after each exercise for comparison.

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 discourseanalysis 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

Contemporary debates over psychoanalytic theory and practice warrant a reconsideration of the concept of wild analysis. Freud's initial formulation of the problem, subsequent developments in the Freudian conventions, and the work of Melanie Klein, Kohut, and Gill are compared in order to bring out different conceptions of interpretation that is wild, sound, or too tame. These different conceptions are system-bound. Moral implications of Klein's, Kohut's, and Gill's critiques and alternative systems are taken up. PMID:4020025

This workbook allows the analysis of sample or imported protein sequences. The model can analyze protein sequences up to 500 amino acids long. The program analyzes five aspects of the protein sequence: the highest potential charge along the protein sequence, the amino acid composition of the protein sequence, the isoelectric point of the protein sequence at varying pHs, the hydrophobicity to predict surface and membrane spanning regions of the protein sequence and the protein structure using the Chau and Fassman algorithm.
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.
This article presents an analysis of two low-performing students' experiences in a first- grade classroom oriented toward teaching mathematics for understanding. Combining constructs from interactional sociolinguistics and developmental task analysis, I investigate the nature of these students' participation in classroom discourse about fractions. Pre- and post-instruction interviews documenting learning and analysis of classroom interactions suggest mechanisms of that learning. I

The United States has the highest incarceration rate of any country. The causes for the large number of prisoners can be traced, in part, to a politicized war on crime that resulted in harsh sentencing and high recidivism rates. Prisoner education provides the potential for slowing the revolving door of prison by helping to create engaged

The Systems Analysis Branch performs trajectory and systems analysis for next-generation launch vehicle and space transportation technologies. Currently the branch is supporting the Project Prometheus with analysis of nuclear electric and nuclear thermal propulsion missions to a variety of destinations. Within Project Prometheus a proposed mission to Jupiter and three of the planet sized icy moons that orbit it is developing. The Jupiter Icy Moons Orbiter (JIMO) as the project is being called will enable detailed scientific investigation of Jupiter's moons Callisto, Ganymede, and Europa. These moons were choose to orbit for intensive study in particular because they are each believed to have water, energy, and organic material. The JIMO mission will utilize nuclear fission power and electric propulsion in order to allow the spacecraft to orbit the moons at close range for long durations of time. My assignment this summer was to assist in developing a trajectory analysis for the spacecraft system the Jupiter Icy Moons Orbiter by rewriting an inefficient Excel file into a more efficient FORTRAN program. This program has been created for use planning the trajectory of the Jupiter Icy Moons Orbiter Mission. The program uses a database of thousands of data points representing flight time, burn time, thrust, mass of the propellant used, final mass of the spacecraft, ratio of finals mass to initial mass, and change in velocity that a spacecraft experiences during each phase in the Jupiter Icy Moons Orbiter Mission. The trajectory program is capable of taking a specific user entered specific impulse (isp), final mass fraction, and thrust (P(sub J)/m0) and through the use of cubic splines to fit specific data curves, the program can locate the exact flight time linked to the user specified values of specific impulse and final over initial mass fraction. Currently, the database used by the program to calculate flight times for a given thrust is only for isps in the range of 2000 to 9000 seconds. Although the program is specific to the Jupiter Icy Moons Orbiter mission, it can be easily modified to fit any mission with a propulsion system expected isp range between 2000 and 9000 seconds. This program performs the same tasks as the old Excel file but in a more timely fashion. Finally, this FORTRAN program will replace the Excel file as the tool used to calculate trajectory properties in missions and will provide valuable data to mission analysts for years to come.
Exploratory calculations were performed for several gas core breeder reactor configurations. The computational method involved the use of the MACH-1 one dimensional diffusion theory code and the THERMOS integral transport theory code for thermal cross sections. Computations were performed to analyze thermal breeder concepts and nonbreeder concepts. Analysis of breeders was restricted to the (U-233)-Th breeding cycle, and computations were performed to examine a range of parameters. These parameters include U-233 to hydrogen atom ratio in the gaseous cavity, carbon to thorium atom ratio in the breeding blanket, cavity size, and blanket size.
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

Deficiencies of natural anticoagulant proteins including antithrombin (AT), protein C (PC) and protein S (PS) are important risk factors for venous thromboembolism (VTE) in Japanese people. The identification of deficiencies of these proteins is important for the prevention and treatment of VTE. Genetic analysis can help in making a definitive diagnosis of these inherited deficiencies, and can be useful both for the individual and potential thrombotic risk to family members. Mutations of AT, PC and PS are usually detected by direct DNA sequencing and multiple ligation-dependent probe amplification (MLPA). Large cohort studies have shown that AT and PC mutations are identified in 85% and 70% of patients, respectively. On the other hand, the detection rate in PS deficiency is lower in around 40% of patients. PMID:25163314
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.

This review is the seventh in the series compiled by using the Dialog on-line CA Search facilities at the Information Resource Center of USS Technical Center covering the period from Oct. 1984 to Nov. 1, 1986. The quest for better surface properties, through the application of various electrochemical and other coating techniques, seems to have increased and reinforces the notion that only through the value added to a steel by proper finishing steps can a major supplier hope to compete profitably. The detection, determination, and control of microalloying constituents has also been generating a lot of interest as evidenced by the number of publications devoted to this subject in the last few years. Several recent review articles amplify on the recent trends in the application of modern analytical technology to steelmaking. Another review has been devoted to the determination of trace elements and the simultaneous determination of elements in metals by mass spectrometry, atomic absorption spectrometry, and multielement emission spectrometry. Problems associated with the analysis of electroplating wastewaters have been reviewed in a recent publication that has described the use of various spectrophotometric methods for this purpose. The collection and treatment of analytical data in the modern steel making environment have been extensively reviewed emphasis on the interaction of the providers and users of the analytical data, its quality, and the cost of its collection. Raw material treatment and beneficiation was the dominant theme.
In the Surface Analysis group, within the National Center for Photovoltaic's Measurements and Characterization Division, we use surface analytical techniques help to determine the chemical, elemental, and molecular composition, and electronic structure of material surfaces and interfaces. The properties of the surface and outer few micrometers of a material often control the electrical, chemical, or mechanical properties of that material--hence, this region is of extreme importance. Our techniques use ions, electrons, and X-ray or ultraviolet photons in high vacuum to probe surfaces and interfaces of a material. We map the elemental and chemical composition of specimens, study impurities and grain boundaries, gather bonding and chemical-state information, measure surface electronic properties, and perform depth profiles to determine doping and elemental distributions. We have analyzed a wide range of materials, including photovoltaics, microelectronics, polymers, and biological specimens. We work collaboratively with you to solve materials- and device-related R&D problems. This sheet describes our major technique capabilities.
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.

This qualitative study investigates the discourses that men used when talking about their experiences of attending a Duluth-cognitive-behavioral-therapy (CBT) domestic violence program in Cape Town, South Africa. Data were collected from 12 men who were recruited from three programs. A discourseanalysis of interviews revealed that men drew upon various dominant discourses of masculinity that may reinforce the subordination of, control over, and violence against women. Our findings from this study contribute to the debate surrounding the Duluth model's effectiveness in South Africa by questioning its successes in transforming violent masculinity. PMID:25341539

Narrative discourse is an essential component of day-to-day communication, but little is known about narrative in Lewy Body spectrum disorder (LBSD), including Parkinson's disease (PD), Parkinson's disease with dementia (PDD), and dementia with Lewy bodies (DLB). We performed a detailed analysis of a semi-structured speech sample in 32 non-aphasic patients with LBSD, and we related their narrative impairments to gray matter (GM) atrophy using voxel-based morphometry. We found that patients with PDD and DLB have significant difficulty organizing their narrative speech. This was correlated with deficits on measures of executive functioning and speech fluency. Regression analyses associated this deficit with reduced cortical volume in inferior frontal and anterior cingulate regions. These findings are consistent with a model of narrative discourse that includes executive as well as language components and with an impairment of the organizational component of narrative discourse in patients with PDD and DLB.

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

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 Next Generation Science Standards (NGSS) identify eight practices as essential to science and engineering, and these practices include asking students to construct explanations, to engage in argumentation, and to communicate scientific information. However, few teacher-training programs instruct teachers how to facilitate such discourse in the classroom. Modeling Instruction is one movement in physics education that organizes high school physics content around a small number of student-derived scientific models, and it relies on student discourse for the design, development, and deployment of these models. This research is a self-study of one high school physics teacher's experience facilitating large group discourse in the high school modeling physics classroom. Whiteboard meetings and graded discussions were examined by applying the analytical framework created by Mortimer and Scott (2003) to characterize the classroom talk and the discourse facilitation moves that I employed. In addition, elements of discourseanalysis were used to examine some of the tensions that I experienced in the facilitation of this discourse. The findings suggest that deliberate identification of the teaching purposes for the discussion can help determine the scaffolding needed for students to enter the Discourse (Gee, 2011) of being a participant in these large group conversations. In addition, connecting the dialogic dimension of exploring student ideas with the authoritative dimension of introducing the scientific view and supporting the internalization of that view is necessary to contribute to meaning making in the science classroom.
Repetition and semantic-associative priming effects have been demonstrated for words in nonstructured contexts (i.e., word pairs or lists of words) in numerous behavioral and electrophysio-logical studies. The processing of a word has thus been shown to benefit from the prior presentation of an identical or associated word in the absence of a constraining context. An examination of such priming effects for words that are embedded within a meaningful discourse context provides information about the interaction of different levels of linguistic analysis. This article reviews behavioral and electrophysiological research that has examined the processing of repeated and associated words in sentence and discourse contexts. It provides examples of the ways in which eye tracking and event-related potentials might be used to further explore priming effects in discourse. The modulation of lexical priming effects by discourse factors suggests the interaction of information at different levels in online language comprehension. PMID:16891554

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

Decarbonising housing is a key UK government policy to mitigate climate change. Using discourseanalysis, we assess how low carbon housing is portrayed within British broadsheet media. Three distinct storylines were identified. Dominating the discourse, Zero carbon housing promotes new-build, low carbon houses as offering high technology solutions to the climate problem. Retrofitting homes emphasises the need to reduce emissions within existing housing, tackling both climate change and rising fuel prices. A more marginal discourse, Sustainable living, frames low carbon houses as related to individual identities and 'off-grid' or greener lifestyles. Our analysis demonstrates that technical and economic paradigms dominate media discourse on low carbon housing, marginalising social and behavioural aspects. PMID:24336448

Motivation: Prior biological knowledge greatly facilitates the meaningful interpretation of gene-expression data. Causal networks constructed from individual relationships curated from the literature are particularly suited for this task, since they create mechanistic hypotheses that explain the expression changes observed in datasets. Results: We present and discuss a suite of algorithms and tools for inferring and scoring regulator networks upstream of gene-expression data based on a large-scale causal network derived from the Ingenuity Knowledge Base. We extend the method to predict downstream effects on biological functions and diseases and demonstrate the validity of our approach by applying it to example datasets. Availability: The causal analytics tools Upstream Regulator Analysis', Mechanistic Networks', Causal Network Analysis' and Downstream Effects Analysis' are implemented and available within Ingenuity Pathway Analysis (IPA, http://www.ingenuity.com). Supplementary information: Supplementary material is available at Bioinformatics online. PMID:24336805

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.

This article is an analysis of talk in breastfeeding workshops that are part of National Childbirth Trust antenatal classes. Using audio-recordings from breastfeeding workshops antenatal classes, the data were analysed using a qualitative, discursive methodology based in part on the premises outlined by Potter and Wetherell (1987) and Edwards and Potter (1992, 2001). The analysis demonstrates how there are two main discourses of breastfeeding constructed by the breastfeeding counsellor-breastfeeding as natural, and breastfeeding as learnt. In particular, it notes how these two main discourses of breastfeeding that are seemingly in competition with one another, operate concurrently within the teaching of breastfeeding, and enable the breastfeeding counsellor to manage issues and concerns around breastfeeding.

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.

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.

This study is concerned with men's talk about emotions and with how emotion discourses function in the construction and negotiation of masculine ways of doing emotions and of consonant masculine subject positions. A sample group of 16 men, who were recruited from two social contexts in England, participated in focus groups on 'men and emotions'. Group discussions were transcribed and analysed using discourseanalysis. Participants drew upon a range of discursive resources in constructing masculine emotional behaviour and negotiating masculine subject positions. They constructed men as emotional beings, but only within specific, rule-governed contexts, and cited death, a football match and a nightclub scenario as prototypical contexts for the permissible/understandable expression of grief, joy and anger, respectively. However, in the nightclub scenario, the men distanced themselves from the expression of anger as violence, whilst maintaining a masculine subject position. These discursive practices are discussed in terms of the possibilities for effecting change in men's emotional lives. PMID:15479538
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.

NASA regulations require that formal risk analysis be performed on a program at each of several milestones as it moves toward full-scale development. 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 simple to complex network-based simulation were surveyed. A Program Risk Analysis Handbook was prepared in order to provide both analyst and manager with a guide for selection of the most appropriate technique.
Asymptotic Modal Analysis (AMA) is a method which is used to model linear dynamical systems with many participating modes. The AMA method was originally developed to show the relationship between statistical energy analysis (SEA) and classical modal analysis (CMA). In the limit of a large number of modes of a vibrating system, the classical modal analysis result can be shown to be equivalent to the statistical energy analysis result. As the CMA result evolves into the SEA result, a number of systematic assumptions are made. Most of these assumptions are based upon the supposition that the number of modes approaches infinity. It is for this reason that the term 'asymptotic' is used. AMA is the asymptotic result of taking the limit of CMA as the number of modes approaches infinity. AMA refers to any of the intermediate results between CMA and SEA, as well as the SEA result which is derived from CMA. The main advantage of the AMA method is that individual modal characteristics are not required in the model or computations. By contrast, CMA requires that each modal parameter be evaluated at each frequency. In the latter, contributions from each mode are computed and the final answer is obtained by summing over all the modes in the particular band of interest. AMA evaluates modal parameters only at their center frequency and does not sum the individual contributions from each mode in order to obtain a final result. The method is similar to SEA in this respect. However, SEA is only capable of obtaining spatial averages or means, as it is a statistical method. Since AMA is systematically derived from CMA, it can obtain local spatial information as well.

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.

This information has been extracted from those draft documents an approved under separate cover so that it can be used as reference material for the DWPF EA when it is placed in the public reading rooms. 9 refs., 4 tabs.
Java Analysis Studio is a desktop data analysis application aimed primarily at offline analysis of high-energy physics data. The goal is to make the application independent of any particular data format, so that it can be used to analyze data from any experiment. The application features a rich graphical user interface (GUI) aimed at making the program easy to learn and use, but which at the same time allows the user to perform arbitrarily complex data analysis tasks by writing analysis modules in Java. The application can be used either as a standalone application, or as a client for a remote Java Data Server. The client-server mechanism is targeted particularly at allowing remote users to access large data samples stored on a central data center in a natural and efficient way.

Given that sentences in dialogic discourse tend to be interrupted with such frequency that incomplete sentences may be considered a normal phenomenon, I adopt the position that the notion of the sentence should be abandoned as a unit of analysis for spontaneous spoken language. In this article, I investigate the possibility that sentences in dialogues are not always constructed by
Most current models of interaction design build on scenarios and task analysis. We think that interaction design should be more along the lines of communication between humans. With this motivation, our paper presents a new approach to modeling interaction design based on insights from theories of human communication. From such discourse models, we aim for automated generation of user interfaces.

This essay offers an analysis of the interplay between the writings of the father of sexology, Henry Havelock Ellis, and the leader of the birth control movement in the United States, Margaret Higgins Sanger. Utilizing the theories of Foucault and Burke, the author argues that Sanger engages in the process of reverse discourse, appropriating language that initially functioned to maintain
We investigated longitudinally the co-constructed narratives of 31 mother-child dyads collected when the children were 3-, 4-, and 5-years old, examining the dual development of child conversational and narrative discourse skills and the impact of maternal verbal assistance.

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."

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.
In this paper the mechanism of a cosmological phase transition is addressed in a new way which avoids weaknesses of previous approaches. The effects of inhomogeneities are included explicitly. A numerical analysis is presented in which for a wide class of models the Universe enters a period of new inflation. The analysis is classical and applies to models in which the scalar field responsible for driving inflation is weakly coupled to other fields. We derive heuristic arguments which determine the boundaries of the region in parameter space for which inflation is realized. The agreement with the numerical results is good. This paper complements a previous analytical analysis.
Structural Reliability Consultants' computer program creates graphic plots showing the statistical parameters of glue laminated timbers, or 'glulam.' The company president, Dr. Joseph Murphy, read in NASA Tech Briefs about work related to analysis of Space Shuttle surface tile strength performed for Johnson Space Center by Rockwell International Corporation. Analysis led to a theory of 'consistent tolerance bounds' for statistical distributions, applicable in industrial testing where statistical analysis can influence product development and use. Dr. Murphy then obtained the Tech Support Package that covers the subject in greater detail. The TSP became the basis for Dr. Murphy's computer program PC-DATA, which he is marketing commercially.

We explore the possibility for elemental analysis by NMR. To keep the efficiency of the signal acquisition common for all spin species, we propose to fix the frequency and vary the magnetic field to cover the isotopes involved in a sample. We introduce constant-frequency receptivity for quantitative elemental analysis in the frequency-fixed NMR experiment. Field-variable NMR experiments are demonstrated using a cryogen-free superconducting magnet. In addition to elemental analysis in liquid solution, solid-state NMR under magic-angle spinning is also described. PMID:23036840

Learning science interpreted in existing theoretical frameworks often means that students are assimilated, accommodated or enculturated from the entity of the vernacular world to the entity of the scientific world. However, there are some unsolved questions as to how students can best learn purely a new language or new knowledge of science. The purpose of this study is to conduct microanalysis of moment-to-moment interactions in order to understand how science language is taught and learned in details. Informed by Bakhtin's dialogism, the analysis indicates that learning science is a process of appropriating authoritative discourse into internally persuasive discourse. Based on our analysis and findings, we propose the framework of discursive evolution to describe the process of teaching and learning the language of science. Four different stages of discursive evolution are identified to demonstrate the discursive changes during the course of science teaching and learning discourse: (a) using deictic references to connect scientific terminologies, (b) understanding science terminologies through its derivatives, (c) communicating science practices conventionally through science terminologies, and (d) communicating science practices innovatively through mutated science terminologies. The findings suggest that science teaching and learning comprise a heterogeneous process which draws on both science and non-science language and is a constantly evolving process. Understanding teaching and learning as a heterogeneous and constantly evolving process allows us to reunite the roles of teachers and students as mutually responsible collaborators rather than science knowledge givers and consumers.

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.

The Design-through-Analysis Realization Team (DART) is chartered with reducing the time Sandia analysts require to complete the engineering analysis process. The DART system analysis team studied the engineering analysis processes employed by analysts in Centers 9100 and 8700 at Sandia to identify opportunities for reducing overall design-through-analysis process time. The team created and implemented a rigorous analysis methodology based on a generic process flow model parameterized by information obtained from analysts. They also collected data from analysis department managers to quantify the problem type and complexity distribution throughout Sandia's analyst community. They then used this information to develop a community model, which enables a simple characterization of processes that span the analyst community. The results indicate that equal opportunity for reducing analysis process time is available both by reducing the ''once-through'' time required to complete a process step and by reducing the probability of backward iteration. In addition, reducing the rework fraction (i.e., improving the engineering efficiency of subsequent iterations) offers approximately 40% to 80% of the benefit of reducing the ''once-through'' time or iteration probability, depending upon the process step being considered. Further, the results indicate that geometry manipulation and meshing is the largest portion of an analyst's effort, especially for structural problems, and offers significant opportunity for overall time reduction. Iteration loops initiated late in the process are more costly than others because they increase ''inner loop'' iterations. Identifying and correcting problems as early as possible in the process offers significant opportunity for time savings.

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.

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.
This article analyzes how heteronormative discourse may be (re)produced by the very same people it serves to oppress, binding heteronormativity to a specific form of homonormativity. Furthermore, this article also links Portuguese history and society by discussing the context and the recent legal changes that led to legislation providing for same-sex marriage. Using thematic analysis of 14 interviews, this article demonstrates how heteronorms are upheld in the discourses of the lesbian, gay, bisexual, and queer (LGBQ) participants. Themes linked to public displays of affection and discrimination emerged from the interviews. Participant discourses are analyzed in terms of their incorporation of heteronorms. Homonormativity is present in both the themes subject to analysis. Analysis of the interviews shows how transgressing the heteronorm implies costs and is ultimately perceived as a personal risk. This article concludes that the lack of discursive resistance denies the possibility of re-signification and subversion even in LGBQ discourses. This clearly indicates the pervasiveness of discourses reiterating heteronorms, even those issued by those most oppressed by such norms. PMID:24059969

My research is a critical examination of environmental science education resources for use in Alberta schools. I examine both the resources and the processes by which these resources are developed by diverse groups. My inquiry is guided by the following question: What is the nature of the discourse of ecological literacy in the promotion and content of teaching materials in elementary schools in Alberta? This critical analysis centres on the discourses, language, and perspectives (both hidden and overt) of these resources and processes; the manifestation of political agendas; existing relations; and the inclusion or exclusion of alternate views. Framed within critical theory and an ecosocial construct, my methodology employs critical discourseanalysis and hermeneutic interpretation. I analyse selected environmental science resources produced for the elementary classroom by government and nongovernment organizations. I also interview the producers and/or writers of these instructional resources to provide the perspectives of some of the developers of these materials. The findings illustrate how the discursive management of the view of nature, human-nature relationships, uncertainty, multiple perspectives, and dimensions of ecological literacy in materials for schools offer students a particular perspective. These ecological and science discourses act to shape their personal relationships with nature and notions of environmental responsibility and consciousness. This research is necessary because, particularly in Alberta, corporate interests have the potential to impact school curricula. The study points to a need for a critical appraisal of resources for schools produced by the environmental science community.

The practice of proximal formative assessment - the continual, responsive attention to students' developing understanding as it is expressed in real time - depends on students' sharing their ideas with instructors and on teachers' attending to them. Rogerian psychology presents an account of the conditions under which proximal formative assessment may be promoted or inhibited: (1) Normal classroom conditions, characterized by evaluation and attention to learning targets, may present threats to students' sense of their own competence and value, causing them to conceal their ideas and reducing the potential for proximal formative assessment. (2) In contrast, discourse patterns characterized by positive anticipation and attention to learner ideas increase the potential for proximal formative assessment and promote self-directed learning. We present an analysis methodology based on these principles and demonstrate its utility for understanding episodes of university physics instruction.

Purpose A microlinguistic content analysis for assessing lexical semantics in people with aphasia (PWA) is lexical diversity (LD). Sophisticated techniques have been developed to measure LD. However, validity evidence for these methodologies when applied to the discourse of PWA is lacking. The purpose of this study was to evaluate four measures of LD to determine how effective they were at measuring LD in PWA. Method Four measures of LD were applied to short discourse samples produced by 101 PWA: (a) the Measure of Textual Lexical Diversity (MTLD; McCarthy, 2005), (b) the Moving-Average Type-Token Ratio (MATTR; Covington, 2007), (c) D (McKee, Malvern, & Richards, 2000), and (d) the Hypergeometric Distribution (HD-D; McCarthy & Jarvis, 2007). LD was estimated using each method, and the scores were subjected to a series of analyses (e.g., curve-fitting, analysis of variance, confirmatory factor analysis). Results Results from the confirmatory factor analysis suggested that MTLD and MATTR reflect LD and little of anything else. Further, two indices (HD-D and D) were found to be equivalent, suggesting that either one can be used when samples are >50 tokens. Conclusion MTLD and MATTR yielded the strongest evidence for producing unbiased LD scores, suggesting that they may be the best measures for capturing LD in PWA. PMID:23695912

The bedside measurement of continuous arterial pressure values from waveform analysis has been routinely available via indwelling arterial catheterization for >50 years. Invasive blood pressure monitoring has been utilized in critically ill patients, in both the operating room and critical care units, to facilitate rapid diagnoses of cardiovascular insufficiency and monitor response to treatments aimed at correcting abnormalities before the consequences of either hypo- or hypertension are seen. Minimally invasive techniques to estimate cardiac output (CO) have gained increased appeal. This has led to the increased interest in arterial waveform analysis to provide this important information, as it is measured continuously in many operating rooms and intensive care units. Arterial waveform analysis also allows for the calculation of many so-called derived parameters intrinsically created by this pulse pressure profile. These include estimates of left ventricular stroke volume (SV), CO, vascular resistance, and during positive-pressure breathing, SV variation, and pulse pressure variation. This article focuses on the principles of arterial waveform analysis and their determinants, components of the arterial system, and arterial pulse contour. It will also address the advantage of measuring real-time CO by the arterial waveform and the benefits to measuring SV variation. Arterial waveform analysis has gained a large interest in the overall assessment and management of the critically ill and those at a risk of hemodynamic deterioration. PMID:25480767

Genetic variation and SNP analysis starts with generation of sequence-specific signal, followed by the collection of that signal. The final step is extensive data analysis, which starts with conversion of quantifiable raw data and ends up with identified SNPs, frequencies, and sometimes tissue-specific expression patterns (levels). In this chapter we describe and compare the mechanisms of signal generation of several representative SNP analysis platforms. DNA microarray no doubt has its advantage in applications involving the classification and identification of tumor classes, gene discovery, drug dependent transcription mechanisms, as well as prediction of drug response. PCR, xMAP, invader assay, mass spectrometry, and pyrosequencing, on the other hand, are alternative methods of genotyping employed following the large scale screening and discovery of genetic variations. In addition, they offer higher specificity and sensitivity in analysis of both genomic DNA, as well as RNA. By exploiting these technologies, correlative study of the effects of putative genetic variations on cells, tissue-specific and developmentally specific expression is possible. Of extreme value are the many forms of Mass Spectrometry in the areas of sensitive, early cancer diagnosis. Finally, microarray and xMAP are suitable for protein analysis. While protein array offers higher throughput, xMAP is more amendable to the native 3D structure of protein molecules. PMID:17265721

The purposes of this study were, based on John Dewey's ideas on experience, to examine how primary students used their own everyday experience and were affected by own and others' experience in science discourse, and to illuminate the implications of experience in science education. To do these, science discourses by a group of six fourth-graders were observed, where they talked about their ideas related to thermal concepts. The data was collected through interviews and open-ended questions, analyzed based on Dewey's perspective, and depicted as the discourse map which was developed to illustrate students' transaction and changing process of students' ideas. The results of the analysis showed typical examples of Dewey's notions of experience, such as the principles of continuity and of transaction and of different types of experience, examples of `the expanded continuity and transaction', and science discourse as inquiry. It was also found that students' everyday experiences played several roles: as a rebuttal for changing their own ideas or others', backing for assurance of their own ideas in individual students' inner changes after discourse with others, and backing for other's ideas. Based on these observations, this study argues that everyday experience should be considered as a starting point for primary students' science learning because most of their experience comes from everyday, not school science, contexts. In addition, to evoke educative experience in science education, it is important for teachers to pay more attention to Dewey's notions of the principles of continuity and of transaction and to their educational implications.
Germany's Central Ethics Committee of the Federal Chamber of Physicians (FCP) and other relevant national actors called for a public discourse on priority setting in health care. Politicians, members of a Federal Joint Committee and health insurance representatives, however, refused to promote or participate in the establishment of a public discussion. A change to that attitude only became apparent after former FCP President Hoppe's opening speech at the annual FCP assembly in Mainz in 2009. The present paper applies the Sociology of Knowledge Approach to Discourse, implemented through Qualitative Content Analysis and elements of Grounded Theory, to examine the development of the national public discourse in leading German print media. It creates a matrix that represents the discourse development between May 2009 and May 2010 and reflects central actors, their "communicative phenomena" and their interactions. Additionally, the matrix has been extended to cover the period until December 2011. Hoppe's arguments for priority setting in health care are faced with a wide opposition assuming opposing prerequisites and thus demanding alternative remedies. The lack of interaction between the different parties prevents any development of the speakers' positions. Incorrect accounts, reductions and left-outs in the media representation add to this effect. Consequently, the public discussion on priority setting is far from being an evolving rational discourse. Instead, it constitutes an exchange of preformed opposing positions. PMID:22857724
This paper investigates the discursive construction of the substantive purposes of environmental assessment (EA). It addresses these purposes by exploring the complex and often multifaceted linkages between political factors and plural views of democracy, public participation, and the role of science that are embedded in environmental and sustainability discourses. The interaction between policy-making and public actors leads to the formulation of divergent and potentially competing rationales for public participation, and for social appraisal more generally. Participatory approaches have also given impetus to the development of several interpretations on the role of science in assessment procedures. Science is important in mediating public participation and the two are therefore reciprocally linked. This leads to discourses that become manifest in the construction of substantive purposes. Discourseanalysis in EA is a relevant method for examining trends and patterns in sustainable development. It is argued that public participation is an important, if not decisive, variable in the articulation and civil legitimacy of certain purposes. A general proposition that results from this paper is that EA, although typically presented as an objective scientific tool, is an intrinsically normative process. Enhanced knowledge on the construction, and reconstruction over time, of substantive purposes is required if environmental and sustainability discourses are to be used and understood as meaningful analytical instruments to assess the socio-political implications of EA. - Highlights: Black-Right-Pointing-Pointer Substantive purposes related to environmental assessment may be best analyzed through discourseanalysis. Black-Right-Pointing-Pointer Environmental and sustainability discourses are contingent on the level of participatory democracy and civic science. Black-Right-Pointing-Pointer Public participation is a decisive variable in the construction of the substantive purpose of environmental assessment.

Storage Battery Systems Analysis supports the battery Exploratory Technology Development and Testing Project with technical and economic analysis of battery systems in various end-use applications. Computer modeling and simulation techniques are used in the analyses. Analysis objectives are achieved through both in-house efforts and outside contracts. In-house studies during FY82 included a study of the relationship between storage battery system reliability and cost, through cost-of-investment and cost-of-service interruption inputs; revision and update of the SOLSTOR computer code in standard FORTRAN 77 form; parametric studies of residential stand-alone photovoltaic systems using the SOLSTOR code; simulation of wind turbine collector/storage battery systems for the community of Kalaupapa, Molokai, Hawaii.
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 portable Contamination Analysis Unit (CAU) measures trace quantifies of surface contamination in real time. The detector head of the portable contamination analysis unit has an opening with an O-ring seal, one or more vacuum valves and a small mass spectrometer. With the valve closed, the mass spectrometer is evacuated with one or more pumps. The O-ring seal is placed against a surface to be tested and the vacuum valve is opened. Data is collected from the mass spectrometer and a portable computer provides contamination analysis. The CAU can be used to decontaminate and decommission hazardous and radioactive surface by measuring residual hazardous surface contamination, such as tritium and trace organics It provides surface contamination data for research and development applications as well as real-time process control feedback for industrial cleaning operations and can be used to determine the readiness of a surface to accept bonding or coatings.

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.

Antibody glycosylation has been shown to change with various processes. This review presents mass spectrometric approaches for antibody glycosylation analysis at the level of released glycans, glycopeptides, and intact protein. With regard to IgG fragment crystallizable glycosylation, mass spectrometry has shown its potential for subclass-specific, high-throughput analysis. In contrast, because of the vast heterogeneity of peptide moieties, fragment antigen binding glycosylation analysis of polyclonal IgG relies entirely on glycan release. Next to IgG, IgA has gained some attention, and studies of its O- and N-glycosylation have revealed disease-associated glycosylation changes. Glycoproteomic analyses of IgM and IgE are lagging behind but should complete our picture of glycosylation's influence on antibody function. PMID:23325769

The purpose of a concept analysis is to examine the structure and function of a concept by defining its attributes and internal structure. Concept analysis can clarify an overused or vague concept and promote mutual understanding by providing a precise operational definition. Mentoring is a concept more fully used by other fields, such as business, than in nursing and may not always translate well for use in nursing. Therefore, clarifying the meaning of the existing concept of mentoring and developing an operational definition for use in nursing are aims of this concept analysis. Mentoring is broadly based and concentrates on developing areas such as career progression, scholarly achievements, and personal development. Mentoring relationships are based around developing reciprocity and accountability between each partner. Mentoring is seen related to transition in practice, role acquisition, and socialization, as a way to support new colleagues. Mentorship is related to nurses' success in nursing practice linked to professionalism, nursing quality improvement, and self-confidence. PMID:24042140
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 results of a study conducted in order to estimate where potential transportation cost savings can be anticipated by using CELSS technology for selected future manned space missions, are presented. Six manned missions ranging from a low earth orbit mission to those associated with asteroids and a Mars sortie are selected from NASA planning forecasts for study during an analysis of the transportation system. Several environmental control and life-support systems which are used in developing life-support closure scenarios are investigated for estimates of weight, volume, and power requirements. It is shown that when the scenarios are combined with the transportation analysis, mission life-support cost estimates are provided.

The design of satellite constellations requires an understanding of the dynamic global coverage provided by the constellations. Even for a small constellation with a simple circular orbit propagator, the combinatorial nature of the analysis frequently renders the problem intractable. Particularly for the initial design phase where the orbital parameters are still fluid and undetermined, the coverage information is crucial to evaluate the performance of the constellation design. We have developed a fast and simple algorithm for determining the global constellation coverage dynamically using image processing techniques. This approach provides a fast, powerful and simple method for the analysis of global constellation coverage.
The purpose of this analysis is to determine the structural response of the 21 pressurized water reactor (PWR) uncanistered fuel (UCF) waste package (WP) to a tipover design basis event (DBE) dynamic load; the results will be reported in terms of stress magnitudes. Finite-element solution was performed by making use of the commercially available ANSYS finite-element code. A finite-element model of the waste package was developed and analyzed for a tipover DBE dynamic load. The results of this analysis were provided in tables and were also plotted in terms of the maximum stress contours to determine their locations.
DIPSO plots spectroscopic data rapidly and combines analysis and high-quality graphical output in a simple command-line driven interactive environment. It can be used, for example, to fit emission lines, measure equivalent widths and fluxes, do Fourier analysis, and fit models to spectra. A macro facility allows convenient execution of regularly used sequences of commands, and a simple Fortran interface permits "personal" software to be integrated with the program. DIPSO is part of the Starlink software collection (ascl:1110.012).

Zen's challenge for behavior analysis is to explain a repertoire that renders analysis itself meaninglessa 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.

Data analysis is of central importance in the education of scientists. This book offers a compact and readable introduction to techniques relevant to physical science students. The material is thoroughly integrated with the popular and powerful spreadsheet package Excel by Microsoft. Excel features of most relevance to the analysis of experimental data in the physical sciences are dealt with in some detail. Fully worked problems reinforce basic principles. Underlying assumptions and range of applicability of techniques are discussed, though detailed derivations of basic equations are mostly avoided or confined to the appendices.
This volume offers the avionic systems engineer a fundamental exposition of the mechanization and error analysis of inertial navigation systems. While the material is applicable to spacecraft and undersea navigation, emphasis is placed upon terrestrial applications on or slightly above the earth's surface. As a result, practical considerations are geared toward those aircraft navigation systems of particular current interest. Extensive use is made of perturbation techniques to develop linearized system equations, whose solutions closely approximate those obtained by nonlinear differential equations. A unified error analysis technique is developed that is applicable to virtually all system configurations. The technique provides a greatly simplified method for comparing the performance of competing system configurations.
Biomedical monitoring programs which were developed to provide a system analysis context for a unified hypothesis for adaptation to space flight are presented and discussed. A real-time system of data analysis and decision making to assure the greatest possible crew safety and mission success is described. Information about man's abilities, limitations, and characteristic reactions to weightless space flight was analyzed and simulation models were developed. The predictive capabilities of simulation models for fluid-electrolyte regulation, erythropoiesis regulation, and calcium regulation are discussed.

An operationally ''secure'' power system is one with low probability of blackout or equipment damage. The power system control processes needed to maintain a designated security level at minimum operating cost are extremely complicated. They increasingly depend upon on-line computer security analysis and optimization. This on-line technology is still relatively new, with enormous further potential. Since security and optimality are normally conflicting requirements of power system control, it is inappropriate to treat them separately. Therefore, they are slowly becoming coalesced into a unified hierarchical mathematical problem formulation: one that is, however, far too complex to afford anything but an approximate, near-optimal solution. The practical validity of this unifying trend relies on being able to incorporate all significant security constraints within the process. The main two current computational tools in this field are contingency analysis and special operations-oriented versions of optimal power flow (OPF). Contingency analysis identifies potential emergencies through extensive ''what if.'' simulations on the power system network. OPF is a major extension ot the conventional dispatch calculation. It can respect system static security limits, and can schedule reactive as well as active power. Moreover, the advanced versions of OPF include or interface with contingency analysis. This paper reviews present formulations and methods, and tries to point out areas of difficulty that constitute the main challenges for successful practical on-line implementations over the coming years.
The STAR collaboration has developed STAF (STAR Analysis Framework), a distributable data analysis framework based upon the software bus concept and implemented using CORBA-compliant(http://www.omg.org) C++ classes. The extended lifetime of the experiment, the prodigious quantity of data to be handled, and the number of collaborators compel us to pay special attention in software design to the maintainability, upgradability, and scalability of the analysis software for STAR. Object-oriented programming techniques provide a powerful tool for the development and maintenance of complex software systems. The emergence of the CORBA software bus standard from the Object Management Group presents a well-accepted industry standard for combining an OOP approach to software development with a software model distributed over a heterogeneous computer network. We are currently using STAF to develop analysis code on simulated data using the familiar KUIP command-line interface from CERN. We present an overview of the design of STAF, some results from our experience with the software environment, plans for distributing STAF components for event parallel processing, and for upgrading the user interface to a distributed, network-based interface using Java(tm) from Sun Microsystems, Inc.
