The organising vision for telehealth and telecare: discourse analysis  

PubMed Central

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

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

PubMed

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

Nursing documentation and nursing practice: a discourse analysis.  

PubMed

Nursing documentation exists as a daily reality of nurses' work. It is interpreted by some as the evidence of nursing actions and dismissed by others as a misrepresentation of nursing care. This paper reports on a study of nursing documentation as nursing practice. The work of Foucault and discourse analysis provide a research design for examination of how written descriptions of patient events taken from patient case notes result from hegemonic influences that construct a knowledge and therefore a practice of nursing. Discourses as ways of understanding knowledge as language, social practices and power relations are used to identify how nursing documentation functions as a manifestation and ritual of power relations. A focus on body work and fragmented bodies provided details of nursing's participation in the discursive construction of the object patient and invisible nurse. It is through resistances to documentation that alternative knowledge of nursing exists. PMID:8807383

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

PubMed

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

Front desk talk: discourse analysis of receptionist-patient interaction  

PubMed Central

Background GP receptionists are the first point of contact with the NHS for most patients and have an important role in facilitating access to healthcare services. There is evidence that they are often perceived as impersonal, insensitive, or officious. Aim To analyse the communicative styles of GP receptionists when dealing with patients. Design of study Ethnographically situated discourse analysis of audio recordings. Setting Three NHS GP surgeries in Scotland. Method Fine-grained transcription and stage-by-stage analysis of digital audio recordings of 283 encounters between receptionists and patients engaged in front desk business. Participants were 16 receptionists and 283 patients. Results Interaction between receptionists and patients consists mainly of verbal routines that are shaped by the administrative tasks completed through them. Receptionists adhere to these established patterns of use at all times, even when dealing with non-routine situations. Within the routine framework, receptionists communicate with patients using styles that display three dominant approaches: task centred, conventionally polite, and rapport building. Receptionists who adopt a task-centred approach use forms with minimal interpersonal content, while those who use conventionally polite forms or those associated with rapport building, give attention to establishing positive relationships with patients. There is no evidence that any stylistic approach is more efficient than another. There is, however, evidence that excessive adherence to routine verbal behaviour has an adverse impact on problem solving. Conclusion Most receptionist discourse consists of the repetition of established verbal routines. Receptionists adopt verbal styles that are predominantly task centred, conventionally polite, or rapport building. Although all three styles enable the completion of reception work with similar levels of efficiency, task-centred styles may appear over-direct. The use of a routine approach when dealing with problematic situations can inhibit and delay their resolution.

Discourse analysis of an 'observation levels' nursing policy.  

PubMed

The practice of special observation (or constant observation) is widely used in inpatient psychiatric facilities for the care of people who are suicidal. In this study, the policy of special observation was examined using a discourse analysis method to discern prevailing ideas and practices highlighted within the policy. After reading, studying and analysing the special observation nursing policy, the authors briefly describe the document and outline the terms and phrases prevalent within the document. These recurrent ideas are then organized into five categories: professional responsibilities, suicidality, the patient's immediate context, the patient's observable behaviour and the nursing checklist. In discussion of the policy document, the invisibility of the authors, target audience and patients is noted. The authors attempt to elicit evidence for the therapeutic nurse-patient relationship in the document. In the analysis of patient, nurse and doctor roles and responsibilities, it is evident that the policy document reinforces the traditional medical hierarchy of power relations. Some assumptions that underpin the document are postulated. Questions regarding the nature of risk assessment and the evidence base for the medical prescription of special observation are raised. As well as ideas and themes evident in the document, the absence of some relevant issues is explored. While the need for succinctness and clarity in policy documents is acknowledged, the fact that patient rights, therapeutic processes and ethical dilemmas are absent is deemed significant.

Scaling discourse analysis refers to the necessity to consider environmental discourse a multi-dimensional and diversified practice. Depending on the various levels of state and society at which environmental policies are applied and depending on the geographical scale at which their solution is sought, we have to differentiate both policy processes and outcomes in environmental politics. We introduce the importance of

Qualitative analysis in gay men's health research: comparing thematic, critical discourse, and conversation analysis.  

PubMed

Gay men's health typically relies on traditional forms of qualitative analysis, such as thematic analysis, and would benefit from a diversity of analytic approaches. Such diversity offers public health researchers a breadth of tools to address different kinds of research questions and, thus, substantiate different types of social phenomenon relevant to the health and wellbeing of gay men. In this article, I compare and contrast three qualitative analytic approaches: thematic, critical discourse, and conversation analysis. I demonstrate and distinguish their key analytic assumptions by applying each approach to a single data excerpt taken from a public health interview conducted for a broader study on gay men's health. I engage in a discussion of each approach in relation to three themes: its utility for gay men's health, its approach to dilemmas of voice, and its capacity for reflexivity. I advocate that qualitative researchers should capitalise on the full range of qualitative analytic approaches to achieve the goals of gay men's health. However, I specifically encourage qualitative researchers to engage with conversation analysis, not only because of its capacity to resolve dilemmas of voice and to achieve reflexivity, but also for its ability to capture forms of social life hitherto undocumented through thematic and critical discourse analysis.

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

PubMed

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.

Prisoners signify: a political discourse analysis of mental illness in a prison control unit.  

PubMed

Increasingly, US prisoners diagnosed with mental illness are housed in control units, the most restrictive form of confinement in the US prison system. This situation has led to intense debate over the legal, ethical and clinical status of mental illness. This is a semiotic struggle with profound effects, yet most related work treats mental illness as a neutral, individual variable. Few analyses locate mental illness within a larger sociopolitical context. Fewer still focus on discursive practice. None critically analyze the accounts of control unit prisoners, who talk about extreme marginality and risk for victimization. This paper has two aims: (i) to develop a systematic method of analysis that accounts for signification as discourse-in-action; and (ii) to show how prisoners' signification of mental illness articulates agency through and against marginalizing discourse. Political discourse analysis demonstrates how control unit prisoners with psychiatric diagnoses signify mental illness, and articulate safer identifications in the process. PMID:17718746

Analyzing psychotherapy process as intersubjective sensemaking: an approach based on discourse analysis and neural networks.  

PubMed

The authors propose a method for analyzing the psychotherapy process: discourse flow analysis (DFA). DFA is a technique representing the verbal interaction between therapist and patient as a discourse network, aimed at measuring the therapist-patient discourse ability to generate new meanings through time. DFA assumes that the main function of psychotherapy is to produce semiotic novelty. DFA is applied to the verbatim transcript of the psychotherapy. It defines the main meanings active within the therapeutic discourse by means of the combined use of text analysis and statistical techniques. Subsequently, it represents the dynamic interconnections among these meanings in terms of a "discursive network." The dynamic and structural indexes of the discursive network have been shown to provide a valid representation of the patient-therapist communicative flow as well as an estimation of its clinical quality. Finally, a neural network is designed specifically to identify patterns of functioning of the discursive network and to verify the clinical validity of these patterns in terms of their association with specific phases of the psychotherapy process. An application of the DFA to a case of psychotherapy is provided to illustrate the method and the kinds of results it produces. PMID:20665338

An Analysis of Teacher Discourse that Introduces Real Science Activities to High School Students  

NASA Astrophysics Data System (ADS)

Most academic science educators encourage teachers to provide their students with access to more authentic science activities. What can and do teachers say to increase students’ interests in participating in opportunities to do real science? What are the discursive resources they draw on to introduce authentic science to students? The purpose of this ethnographic and discourse-analytic study is to investigate the ways in which the activities of scientists are discursively presented to high school students in a biology/career preparation course. Data sources were collected by means of observation, field notes, interviews, and videotaped lessons in an eleventh-grade biology/career preparation course. Drawing on discourse analysis, we investigate the discursive resources—or, more specifically and technically, the interpretative repertoires—teachers used to explain and promote opportunities to engage students in real science activities. Our analysis identifies and characterizes six types of interpretative repertoires: specialized, a-stereotypical, relevant, empirical, emotive, and rare-opportunity. To better understand the “big picture” of how these discursive resources are drawn on in the classroom, we also report on the frequencies of the repertoires in the discourse and the ways in which repertoires changed in the course of teacher-student interactions. The findings of this case study offer teachers and researchers with a better understanding of how specific forms of discourse—i.e., the repertoires—can serve as resources to enhance teacher-introduction of authentic science to students and provide students a bridge between school and authentic science.

Exploring the communication between telenurse and caller--A critical discourse analysis  

PubMed Central

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

Accounting for Accountability: A Discourse Analysis of Psychiatric Nurses' Experience of a Patient Suicide  

PubMed Central

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. Discourse analysis 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 discourse analysis in this setting.

Image, measure, figure: a critical discourse analysis of nursing practices that develop children.  

PubMed

Motivated by discourses that link early child development and health, nurses engage in seemingly benign surveillance of children. These practices are based on knowledge claims and technologies of developmental science, which remain anchored in assumptions of the child body as an incomplete form with a universal developmental trajectory and inherent potentiality. This paper engages in a critical discursive analysis, drawing on Donna Haraway's conceptualizations of technoscience and figuration. Using a contemporary developmental screening tool from nursing practice, this analysis traces the effects of this tool through production, transformation, distribution, and consumption. It reveals how the techniques of imaging, abstraction, and measurement collide to fix the open, transformative child body in a figuration of the developing child. This analysis also demonstrates how technobiopower infuses nurses' understandings of children and structures developmentally appropriate expectations for children, parents, and nurses. Furthermore, it describes how practices that claim to facilitate healthy child development may inversely deprive children of agency and foster the production of normal or ideal children. An alternative ontological perspective is offered as a challenge to the individualism of developmental models and other dominant ideologies of development, as well as practices associated with these ideologies. In summary, this analysis argues that nurses must pay closer attention to how technobiopower infuses practices that monitor and promote child development. Fostering a critical understanding of the harmful implications of these practices is warranted and offers the space to conceive of human development in alternate and exciting ways. PMID:23745662

Home healthcare and family responsibility: a critical discourse analysis of talk and text.  

PubMed

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

'I just want to be normal': An analysis of discourses of normality among recovering heroin users.  

PubMed

Research that has explored the lives of men and women recovering from heroin addiction has reported that users often claim that they 'just want to be normal'. Working within a Foucauldian tradition, we argue in this article that the notions of 'governmentality' and the 'norm' are especially apposite to understanding the ubiquity of this aspiration. Here we focus not on the formal institutions of governance that encourage individuals to adhere to social, cultural and political norms, but rather seek to explore recovering users' accounts of normality as they are envisaged and expressed. The reported empirical data were generated from interviews with 40 men and women in England at various stages of recovery from heroin use. The analytic focus is upon the accounts of normality articulated during the interviews in order to identify the ways in which being normal is presented by the participants. In keeping with the methodological tradition of discourse analysis we identify six discursive repertoires of 'normality talk' that transcend the accounts. It is concluded that the negotiation of normality is a precarious route for this social group. Articulations of a desire to be normal are replete with tensions; there are expressions of both resistance and resignation. Despite claims by some contemporary social theorists that diversity is the 'new normality', the accepted bounds of 'difference' are limited for those who have been addicted to heroin. PMID:22763795

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

NASA Astrophysics Data System (ADS)

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

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

PubMed

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

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

NASA Astrophysics Data System (ADS)

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.

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

NASA Astrophysics Data System (ADS)

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

A causal analysis relating previous achievement, attitudes, discourse, and intervention to achievement in biology and chemistry  

NASA Astrophysics Data System (ADS)

This study described the relationship of 38 variates to achievement in high school biology and chemistry classes. Forty-four teachers prepared audio tape recordings of discussions throughout a nine-month period. Equal-sized groups received treatment consisting of wait time feedback and/or supportive intervention, a form of peer coaching. Other variables were initial measures, which included the variates of class size and previous science grade, pre- and posttest scores on student attitudes and perceptions, and prediscourse and discourse analyses, which included the variates of wait times, actions, and response durations. While previous research has shown that wait time feedback and supportive intervention are effective means of changing teacher behavior, the results of the present study revealed that previous student achievement and the attitudes of students accounted for 70% of the variation in the final examination scores (New York State Regents) on the basis of only the first three weeks of data collection on the variables assessed. Generally, little emphasis on higher-level thinking, wait time, or problem solving was found at the beginning of the school year, and only minimal changes resulted from the application of the treatment variables. Pressures for content coverage and preparation for externally imposed statewide examinations that emphasize memory-level learning augured against the changes that the independent variables were designed to produce.

Pap smear brochures, misogyny and language: a discourse analysis and feminist critique.  

PubMed

Text from a public health brochure on pap smears was analysed with particular reference to ways in which the language used conveys particular messages about women and their bodies. In the text, 'humans' were found to be excluded as such. Both the pap smear service provider and the women who are the recipients of this service--and at whom such brochures are targeted--are objectified and their characteristics of human existence (i.e. ontological capacities) were restricted. The language of the pamphlet invokes an image for women associated with vaginal (penile penetrative) sex. The discourse also is found to be didactic, biomedical and written in the voice of the service provider. Further, the encounter of pap smear events is contextualized as procedural such that not only is the woman 'done to' in the process of having a cervical smear test but the woman's and provider's experiences of the encounter are silenced. It is concluded that the texts may be viewed as misogynist and that such texts do not take account of the complexity of women's decisions to 'submit to' or comply with cervical cancer screening.

Children as agents of their own health: exploratory analysis of child discourse in Spain.  

PubMed

The promotion of children's decision-making is one of the principles of health-promoting schools, and the empowerment of children means that they are enabled to influence their lifestyles and living conditions. The aim of this study was to find out the suggestions of Spanish school pupils in Year 3 and Year 6 of primary education to promote their own health and the health of the people closer to them, through their ideas about health. We analyse the discourse on health in the school environment from focus groups of primary school pupils aged around 8 and 12 of five schools in the town of Alicante (Spain). The groups were organized according to the type of school (public, private), the socioeconomic status of the neighbourhood (residential, working-class) and gender (single-sex, mixed groups) to ensure both the highest intergroup diversity and intra-group homogeneity. The findings show that primary school pupils have a wide and diverse notion of health. The application of the focus group technique has proved useful in eliciting information from groups of primary school pupils, and involving students in health-promoting programmes because it allows them to identify the social and interpersonal determinants of health. There is a firm basis to consider school pupils as health agents, particularly regarding interventions within the school environment itself. With the support of teachers, it is possible to train school pupils as community health agents, and increase their control over their own health. PMID:22669915

Conversational analysis of medical discourse in rehabilitation: A study in Korea  

PubMed Central

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 physician–patient 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.

Selling patients and other metaphors: a discourse analysis of the interpretive frames that shape emergency department admission handoffs.  

PubMed

This paper reports a discourse analysis 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.

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

PubMed Central

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

Analysis of the use of an accidental competency discourse as a reflective tool for professional placement students  

Microsoft Academic Search

Situated learning in professional practice is increasingly recognized as a key component of engineering curricula. One challenge in this context is to establish a reflexive link between the students' learning at university and their experiences in practice. This paper proposes the accidental competency discourse as an alternative tool to support students' experiential learning through reflection on critical learning events. The

A discourse analysis on how service providers in non-medical primary health and social care services understand their roles in mental health care.  

PubMed

Enhancing collaboration between specialist mental health services, primary health care and social care services has been a key priority in mental health policy reform in many countries for about 20 years and remains so. Yet progress in terms of widespread implementation of demonstrably effective models of collaborative care has been slow. The views that different providers hold regarding the parameters of their roles, and the values that guide their approach to service delivery, are likely to exert profound effects on engagement with collaborative initiatives. Little research has explored these issues. In this study, discourse analysis from a structurational perspective was used to explore the views of providers in a diverse purposive sample of non-medical primary health and social care services in the state of Victoria, Australia regarding their mental health care roles. Four interconnected discourses were revealed as supporting role positions constructed in opposition to the putative role positions of specialist mental health services: an informal as opposed to a formal approach; a normalising as opposed to a pathologising approach; holistic social and emotional health and wellbeing, and an individualised or client-focused model of care as opposed to an illness-focused model. These oppositional role constructions may contribute to reluctance among providers in these sectors to engage with some agendas being promoted by specialist mental health services, through either reduced self-efficacy or active resistance to innovations that conflict with strongly held values. Greater awareness of, and critical reflection upon, contrasting role constructions, and the implications of these for practice may facilitate the design of more appropriate collaborative models and stronger commitment to their implementation.

Producing children in the 21st century: a critical discourse analysis of the science and techniques of monitoring early child development.  

PubMed

The purpose of this article is to identify the implications of commonly held ideologies within theories of child development. Despite critiques to doing so, developmental theory assumes that children's bodies are unitary, natural and material. The recent explosion of neuroscience illustrates the significance of historical, social and cultural contexts to portrayals of brain development, offering the opportunity for a critical departure in thinking. Instead, this neuroscience research has been taken up in ways that align with biomedical traditions and neoliberal values. This article uses a critical discursive approach, supported by Haraway's ideas of technoscience, to analyse a population-based early child development research initiative. This initiative organises a large-scale surveillance of children's development, operating from the premise that risks to development are best captured early to optimise children's potential. The analysis in this article shows an intermingling of health and economic discourses and clarifies how the child is a figure of significant contemporary social and political interests. In a poignant example of technobiopolitics, the collusion between health research, technologies and the state enrols health professionals to participate in the production of children as subjects of social value, figured as human capital, investments in the future, or alternatively, as waste. The analysis shows how practices that participate in what has become a developmental enterprise also participate in the marginalisation of the very children they intend to serve. Hence, there is the need to rethink practices critically and move towards innovative conceptualisations of child development that hold possibilities to resist these figurations. PMID:23345326

Expanding discourse repertoires with hybridity  

NASA Astrophysics Data System (ADS)

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

Ottawa to Bangkok: changing health promotion discourse.  

PubMed

The discourse of the 2005 Bangkok Charter for Health Promotion in a Globalized World represents a radical departure from that of the Ottawa Charter that, in 1986, staked a place for the health promotion field in mainstream public health. Via a critical analysis of the discourse in these two Charters, this paper illustrates a shift from a 'new social movements' discourse of ecosocial justice in Ottawa to a 'new capitalist' discourse of law and economics in Bangkok. The Bangkok Charter's content may identify 'actions, commitments and pledges required to address the determinants of health in a globalized world through health promotion', but this paper shows how its discourse works to naturalize and perpetuate many of detrimental determinants associated with 'globalization'.

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

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

The role of language has as yet been largely neglected in studies of European integration. This article provides the theoretical groundwork to remedy this gap through discourse analysis. Its main argument is that attempts to capture the EU's nature both in the political and the academic debate themselves take part in the construction of the Euro-polity. The article proceeds in

Qualitative data analysis: conceptual and practical considerations.  

PubMed

Qualitative inquiry requires that collected data is organised in a meaningful way, and this is referred to as data analysis. Through analytic processes, researchers turn what can be voluminous data into understandable and insightful analysis. This paper sets out the different approaches that qualitative researchers can use to make sense of their data including thematic analysis, narrative analysis, discourse analysis and semiotic analysis and discusses the ways that qualitative researchers can analyse their data. I first discuss salient issues in performing qualitative data analysis, and then proceed to provide some suggestions on different methods of data analysis in qualitative research. Finally, I provide some discussion on the use of computer-assisted data analysis. PMID:19642962

Neurobiology in public and private discourse: the case of adults with ADHD.  

PubMed

How do people describe their health? How do their descriptions relate to public definitions? This article focuses on adult attention deficit hyperactivity disorder (ADHD). We look at Dutch adults who adopt the ADHD label and ask: which discourses structure their descriptions of ADHD? How do these relate to the dominant public discourse on ADHD? Do people use, for example, neurobiological explanations of ADHD? The research makes use of Q-methodology, which combines a discursive relational approach with factor analysis. We examine five different personal discourses that partly differ from the public discourse. People borrow neurobiological, psychological, sociological and even holistic arguments from public discourse to come up with a distinct set of discourses. Neurobiology resonates among adults with ADHD but does not dominate their thinking. Contrary to our expectation, this supports reflexivity instead of discipline theory. PMID:22738075

As in the previous article, this review covers the time period in Chemical Abstracts, Thermal Analysis (CA Selects), from about December 1, 1983, to November 1, 1985. An attempt was made to keep the number of citations as small as possible and yet include the impact of thermal analysis studies to chemistry and allied fields. This was difficult because of the large number of publications in this area during the past 2 years. However, by a subjective evaluation process, a list of citations was chosen so that, in the author's opinion, they represented the essence of the work that was published during the above time period. The abbreviations used here conform to the recommendations of the International Confederation for Thermal Analysis (ICTA), except in the cases where it was a new technique and the name has not yet been approved by this organization. Familiar abbreviations include TG for thermogravimetry, DTA for differential thermal analysis, DSC for differential scanning calorimetry, and EGA for evolved gas analysis. Newer terms are TCA for thermocentrifugometric analysis, TMA for thermomagnetic analysis (not thermomechanical analysis), TCS for thermally stimulated charge, and TVD for thermal voltaic detection. For abbreviations that are questionable, they are defined the first time that they are cited. 164 references.

Metabolic Analysis  

NASA Astrophysics Data System (ADS)

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.

Multivariable Analysis  

NASA Astrophysics Data System (ADS)

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.

Quantitative analysis  

PubMed Central

Quantitative analysis permits the isolation of invariant relations in the study of behavior. The parameters of these relations can serve as higher-order dependent variables in more extensive analyses. These points are illustrated by reference to quantitative descriptions of performance maintained by concurrent schedules, multiple schedules, and signal-detection procedures. Such quantitative descriptions of empirical data may be derived from mathematical theories, which in turn can lead to novel empirical analyses so long as their terms refer to behavioral and environmental events. Thus, quantitative analysis is an integral aspect of the experimental analysis of behavior.

Methodology discourses as boundary work in the construction of engineering education.  

PubMed

Engineering education research is a new field that emerged in the social sciences over the past 10 years. This analysis of engineering education research demonstrates that methodology discourses have played a central role in the construction and development of the field of engineering education, and that they have done so primarily through boundary work. This article thus contributes to science and technology studies literature by examining the role of methodology discourses in an emerging social science field. I begin with an overview of engineering education research before situating the case within relevant bodies of literature on methodology discourses and boundary work. I then identify two methodology discourses--rigor and methodological diversity--and discuss how they contribute to the construction and development of engineering education research. The article concludes with a discussion of how the findings relate to prior research on methodology discourses and boundary work and implications for future research. PMID:24941615

Characteristics of Pre-Service Teachers' Online Discourse: The Study of Local Streams  

NASA Astrophysics Data System (ADS)

This study describes the characteristics of pre-service teachers' discourse on a WebCT Bulletin Board in their investigations of local streams in an integrated mathematics and science course. A qualitative analysis of data revealed that the pre-service teachers conducted collaborative discourse in framing their research questions, conducting research and writing reports. The science teacher educator provided feedback and carefully crafted prompts to help pre-service teachers develop and refine their work. Overall, the online discourse formats enhance out-of-class communication and support collaborative group work. But the discourse on the critical examination of one another's point of views rooted in scientific inquiry appeared to be missing. It is suggested that pre-service teachers should be given more guidance and opportunities in science courses in carrying out scientific discourse that reflects reform-based scientific inquiry.

The discourse of causal explanations in school science  

NASA Astrophysics Data System (ADS)

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

Investigating Science Discourse in a High School Science Classroom  

NASA Astrophysics Data System (ADS)

Science classrooms in the United States have become more diverse with respect to the variety of languages spoken by students. This qualitative study used ethnographic methods to investigate the discourse and practices of two ninth grade science classrooms. Approximately 44% of students included in the study were designated as English learners. The present work focused on addressing the following questions: 1) In what ways is science discourse taken up and used by students and their teacher? 2) Are there differences in how science discourse is used by students depending on their English language proficiency? Data collection consisted of interviewing the science teacher and the students, filming whole class and small group discussions during two lesson sequences, and collecting lesson plans, curricular materials, and student work. These data were analyzed qualitatively. Findings indicated that the teacher characterized science discourse along three dimensions: 1) the use of evidence-based explanations; 2) the practice of sharing one's science understandings publically; and 3) the importance of using precise language, including both specialized (i.e., science specific) and non-specialized academic words. Analysis of student participation during in-class activities highlighted how students progressed in each of these science discourse skills. However, this analysis also revealed that English learners were less likely to participate in whole class discussions: Though these students participated in small group discussions, they rarely volunteered to share individual or collective ideas with the class. Overall, students were more adept at utilizing science discourse during class discussions than in written assignments. Analysis of students' written work highlighted difficulties that were not visible during classroom interactions. One potential explanation is the increased amount of scaffolding the teacher provided during class discussions as compared to written assignments. In the implications section, I provide science teachers with recommendations regarding how to promote science discourse in their classrooms. Specifically, teachers should provide students structured opportunities to practice science discourse, require students to use both written and oral modalities in assignments, and offer timely feedback to students regarding their progress in developing their science discourse skills. How this study contributes to the research base on the teaching of science and English learners will also be described.

Trajectory Analysis  

NASA Technical Reports Server (NTRS)

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.

Predicting gender from electronic discourse.  

PubMed

There is substantial evidence of gender differences in face-to-face communication, and we suspect that similar differences are present in electronic communication. We designed three studies to examine gender-preferential language style in electronic discourse. In Expt 1, participants sent electronic messages to a designated 'netpal'. A discriminant analysis showed that it was possible to successfully classify the participants by gender with 91.4% accuracy. In Expts 2 and 3, we wanted to determine whether readers of e-mails could accurately identify author gender. We gave participants a selection of messages from Expt 1 and asked them to predict the author's gender. It was found that for 14 of the 16 messages used, the gender of author was correctly predicted. In the third experiment, six messages about gender-neutral topics were composed. Using a subset of the variables identified in Expt 1, female and male versions of each message were created. When participants were asked to rate whether a female or a male wrote these messages, their ratings differed as a function of the message version. These findings establish that people use gender-preferential language in informal electronic discourse. Furthermore, readers of these messages can use these gender-linked language differences to identify the author's gender. PMID:11446227

Data Analysis  

SciTech Connect

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

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

Multimodal science teachers' discourse in modeling the water cycle  

NASA Astrophysics Data System (ADS)

The paper presents an intensive study of a micro-event aiming at the characterization of teacher's discourse from a multimodal communication perspective in a secondary school science classroom dealing with the topic of water cycle. The research addresses the following questions: (a) What communicative modes are used by the teacher?, (b) what role do the different communicative modes play within teacher's discourse?, and (c) what are the relationships among communicative modes being used by the teacher? Theoretical framework is developed based on three strands: multimodal communication, science teaching and learning as modeling, and social semotics and Halliday's functional grammar. An analytic scheme guiding teachers' discourse analysis is presented and results discussed. Implications for science teacher education are drawn that would contribute to the improvement of science teacher education.

CDM analysis  

NASA Technical Reports Server (NTRS)

The C Data Manager (CDM) is an advanced tool for creating an object-oriented database and for processing queries related to objects stored in that database. The CDM source code was purchased and will be modified over the course of the Arachnid project. In this report, the modified CDM is referred to as MCDM. Using MCDM, a detailed series of experiments was designed and conducted on a Sun Sparcstation. The primary results and analysis of the CDM experiment are provided in this report. The experiments involved creating the Long-form Faint Source Catalog (LFSC) database and then analyzing it with respect to following: (1) the relationships between the volume of data and the time required to create a database; (2) the storage requirements of the database files; and (3) the properties of query algorithms. The effort focused on defining, implementing, and analyzing seven experimental scenarios: (1) find all sources by right ascension--RA; (2) find all sources by declination--DEC; (3) find all sources in the right ascension interval--RA1, RA2; (4) find all sources in the declination interval--DEC1, DEC2; (5) find all sources in the rectangle defined by--RA1, RA2, DEC1, DEC2; (6) find all sources that meet certain compound conditions; and (7) analyze a variety of query algorithms. Throughout this document, the numerical results obtained from these scenarios are reported; conclusions are presented at the end of the document.

Ferrous analysis

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.

Uncertainty analysis  

SciTech Connect

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.

The discourse of gay men's group sex: The importance of masculinity.  

PubMed

Group sex has consistently been identified as one of a group of risk behaviours among gay men associated with HIV seroconversion. This paper presents a detailed description of how gender, and specifically masculinity, operates as an aspect of the discourse of gay men's group sex. The findings presented in this paper are one part of a multi-aspected discourse analysis through which we are aiming to develop an account of the discourse of gay men's group sex as it was produced in a series of qualitative interviews conducted with gay men who participate in group sex. The interviews were conducted as part of the Three or More Study (TOMS), a larger project that involved a substantial quantitative component. The overarching intent of the discourse analysis is to provide as comprehensive a mapping as possible of this discursive terrain to facilitate the targeted development of HIV and sexual health educational initiatives. The discourse of gay men's group sex reproduces some key formations of masculinity within discourses of gender, which present specific challenges for HIV prevention education. These challenges are outlined at the conclusion of this paper. PMID:19444685

Disciplinary discourses: rates of cesarean section explained by medicine, midwifery, and feminism.  

PubMed

In the context of international concern about increasing rates of cesarean sections, we used discourse analysis to examine explanations arising from feminism and the disciplines of medicine and midwifery, and found that each was positioned differently in relation to the rising rates. Medical discourses asserted that doctors are authorities on birth and that, although cesareans are sometimes medically necessary, women recklessly choose unnecessary cesareans against medical advice. Midwifery discourses portrayed medicine as paternalistic toward both women and midwifery, and feminist discourses situated birth and women's bodies in the context of a patriarchally structured society. The findings illustrate the complex ways in which this intervention in birth is discursively constructed, and demonstrate its significance as a site of disciplinary conflict. PMID:18437594

Instructors often give prompts that encourage students to articulate their beliefs and conceptions, as well as encourage students to understand the thoughts of their peers. This reflective discourse is used in a calculus-based introductory physics class at Lane Community College, where the instructor explicitly has discourse goals integrated into his course structure. We investigate whether students utilize this discourse when solving problems outside of the classroom context. We interviewed groups of students after the end of spring term, 2012. The students were asked to solve open-ended problems, with analysis focused on whether students applied this reflective discourse. Students were asked a series of follow-up questions to reflect upon their experiences in the course.

When discourses collide: creationism and evolution in the public sphere  

NASA Astrophysics Data System (ADS)

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.

Alpha factor analysis  

Microsoft Academic Search

A distinction is made between statistical inference and psychometric inference in factor analysis. After reviewing Rao's canonical factor analysis (CFA), a fundamental statistical method of factoring, a new method of factor analysis based upon the psychometric concept of generalizability is described. This new procedure (alpha factor analysis, AFA) determines factors which have maximum generalizability in the Kuder-Richardson, or alpha, sense.

Data analysis management  

SciTech Connect

Data analysis management is a methodology to assist the analyst in tracking the events of data analysis by allowing the analyst to designate milestones of the analysis, which we call ''save-states''. A prototype data analysis management system, which is described in this paper, includes capabilities to graphically depict the course of the analysis, the ability to return to previous save-states, the ability to use segments of the log that describe the course of the analysis, and the ability to associate both written and spoken documentation with the analysis. 6 refs., 3 figs.

Discourses of the body in euthanasia: symptomatic, dependent, shameful and temporal.  

PubMed

This theoretical paper is derived from a discourse analysis of the textual material from a study of the seven deaths associated with legalised euthanasia in the Northern Territory, Australia. The textual analysis utilises evidence from interviews, letters written by people seeking euthanasia, medical reports, coroner's records and media reports concerning the social experiment of legalised euthanasia in Australia. The paper does not discuss the euthanasia debate. It argues that the body is a neglected concern in the debates and offers a construction of the discourses of the body as symptomatic, dependent, shameful and temporal. Medical discourses frame the body as symptomatic but these people were also concerned with the loss of autonomy associated with dependence, with shame connected with loss of bodily functions and the embodied experience of determining a 'time to die'.

Multivariate meta-analysis: Potential and promise  

PubMed Central

The multivariate random effects model is a generalization of the standard univariate model. Multivariate meta-analysis is becoming more commonly used and the techniques and related computer software, although continually under development, are now in place. In order to raise awareness of the multivariate methods, and discuss their advantages and disadvantages, we organized a one day ‘Multivariate meta-analysis’ event at the Royal Statistical Society. In addition to disseminating the most recent developments, we also received an abundance of comments, concerns, insights, critiques and encouragement. This article provides a balanced account of the day's discourse. By giving others the opportunity to respond to our assessment, we hope to ensure that the various view points and opinions are aired before multivariate meta-analysis simply becomes another widely used de facto method without any proper consideration of it by the medical statistics community. We describe the areas of application that multivariate meta-analysis has found, the methods available, the difficulties typically encountered and the arguments for and against the multivariate methods, using four representative but contrasting examples. We conclude that the multivariate methods can be useful, and in particular can provide estimates with better statistical properties, but also that these benefits come at the price of making more assumptions which do not result in better inference in every case. Although there is evidence that multivariate meta-analysis has considerable potential, it must be even more carefully applied than its univariate counterpart in practice.

Causal analysis approaches in Ingenuity Pathway Analysis  

PubMed Central

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.

Environment and mobility: a view from four discourses.  

PubMed

Debate and literature on the link between degrading environments and human mobility has been increasing exponentially. There is little concrete evidence, however, of efforts or policies that support the management of environmentally influenced mobility. Through discourse analysis using Q-methodology, this research aimed to scrutinize the standoff between opposing views under a fresh lens. One-hundred and ninety-seven experts from 49 nations completed an on-line survey asking them to sort, by level of agreement, 42 statements gleaned from the literature concerning the environment-mobility nexus. Four very different discourses emerged: determined humanists, benevolent pragmatists, cynical protectionists, and critical realists. The complexity of these discourses helps explain the stalemate while confirming the inappropriateness of one-sided terminology and linear quantifications. Despite diametrically opposed viewpoints, experts unanimously agree that human mobility is connected to environmental change. Dissection of these social perspectives builds a new foundation for the Rio+20 analysis and policy deliberations related to environmentally influenced human mobility. PMID:22926825

Death and football: an analysis of men's talk about emotions.  

PubMed

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 discourse analysis. 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

Coh-metrix: analysis of text on cohesion and language.  

PubMed

Advances in computational linguistics and discourse processing have made it possible to automate many language- and text-processing mechanisms. We have developed a computer tool called Coh-Metrix, which analyzes texts on over 200 measures of cohesion, language, and readability. Its modules use lexicons, part-of-speech classifiers, syntactic parsers, templates, corpora, latent semantic analysis, and other components that are widely used in computational linguistics. After the user enters an English text, CohMetrix returns measures requested by the user. In addition, a facility allows the user to store the results of these analyses in data files (such as Text, Excel, and SPSS). Standard text readability formulas scale texts on difficulty by relying on word length and sentence length, whereas Coh-Metrix is sensitive to cohesion relations, world knowledge, and language and discourse characteristics.

A Computational Approach to Qualitative Analysis in Large Textual Datasets  

PubMed Central

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.

Strategic Analysis Overview  

NASA Technical Reports Server (NTRS)

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.

HAZARD ANALYSIS SOFTWARE  

SciTech Connect

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

NASA trend analysis procedures  

NASA Technical Reports Server (NTRS)

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.

The workings of homonormativity: lesbian, gay, bisexual, and queer discourses on discrimination and public displays of affections in Portugal.  

PubMed

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

Discourse of 'transformational leadership' in infection control.  

PubMed

The article explores the impact of the ;transformational leadership' style in the role of modern matron with regards to infection control practices. Policy and guidance on the modern matron role suggest that it is distinctive in its combination of management and clinical components, and in its reliance on transformational leadership. Senior nurses are therefore expected to motivate staff by creating high expectations, modelling appropriate behaviour, and providing personal attention to followers by giving respect and responsibility. In this article, we draw on policy documents and interview data to explore the potential impact of this new management style on infection control practices. Combining the techniques of discourse analysis and corpus linguistics, we identify examples where matrons appear to disassociate themselves from the role of ;an empowered manager' who has control over human and financial resources to resolve problems in infection control efficiently.

Promoting proximal formative assessment with relational discourse  

NSDL National Science Digital Library

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.

Learning as discourse change: A sociocultural mechanism  

NASA Astrophysics Data System (ADS)

This paper deals with a theoretical mechanism for learning and a methodological approach for analyzing meaning making in classroom talk and action. It examines the potential of the approach for illuminating learning on a discursive level, i.e., how discourses change and how individuals become participants of new practices. Our approach involves a high-resolution analysis of how meaningful relations are built in encounters between individuals and between individuals and the world. The approach is based mainly on the work of the later Wittgenstein, but also on pragmatism and sociocultural research. To demonstrate how our approach can be used, we analyze what university students learn during a practical on insects. We specifically demonstrate how the encounters with physical pinned insects contribute to the meaning students make and how these encounters interact with other experiences during laboratory work.

STUDY OBJECTIVE—To determine the ways in which institutions devoted to international development influence epidemiological studies.?DESIGN—This article takes a descriptive epidemiological study of El Salvador, Epidemiological Profile, conducted in 1994 by the US Agency for International Development, as a case study. The methods include discourse analysis in order to uncover the ideological basis of the report and its characteristics as a discourse of development.?SETTING—El Salvador.?RESULTS—The Epidemiological Profile theoretical basis, the epidemiological transition theory, embodies the ethnocentrism of a "colonizer's model of the world." This report follows the logic of a discourse of development by depoliticising development, creating abnormalities, and relying on the development consulting industry. The epidemiological transition theory serves as an ideology that legitimises and dissimulates the international order.?CONCLUSIONS—Even descriptive epidemiological assessments or epidemiological profiles are imbued with theoretical assumptions shaped by the institutional setting under which epidemiological investigations are conducted.???Keywords: El Salvador; politics

Quantitative cytokinetic analysis reviewed

The importance of mathematical analysis in the field of cell kinetics is increasing as new experimental tools make apparent the complexity of the cytokinetic behavior of all populations. Intuitive or casual interpretation of such complex behavior is becoming increasingly difficult. Thus future cytokinetic understanding will almost certainly come from mathematical analysis of careful experiments and will depend heavily on the degree to which biologists and biomathematicians can work together to develop mathematical analysis that are biologically reasonable.

Why Everyday Experience? Interpreting Primary Students' Science Discourse from the Perspective of John Dewey  

NASA Astrophysics Data System (ADS)

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.

Measuring Lexical Diversity in Narrative Discourse of People With Aphasia  

PubMed Central

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.

The disruptive consequences of discourse fragmentation in the organization and delivery of health care: a look into diabetes.  

PubMed

The aim of this study is to contribute to a better understanding about how discourse fragmentation is affecting the way doctors perceive the patient's role and expectations that are being redefined under the influence of media and other information sources. The diabetes case provides the empirical evidence to support the fragmentation thesis. This condition offers a unique mix of complexity, scope, and controversy to understand the dialectics of discourse fragmentation. Through a combined analysis of media discourse and experts' discourse (researchers and clinicians), this article describes the connections between the macro (the realm of the public sphere) and the micro (the localized medical practice) in the context of health care delivery. The study concludes that a fragmented media discourse tends at the same time to nourish the public perception about the "diabetes complexities" (a multifaceted and growing epidemic), and to normalize some emerging concepts such as "prediabetes" and metabolic syndrome. This fragmentation seems to have a double-edged sword effect on doctor-patient relationships; in some occasions the atomized discourse about diabetes has a clear disruptive impact on their medical practice, adding an "extra burden" to the disease management, while in other opportunities it has a more convergent effect facilitating the dialogue and the interaction between the actors.

Asymptotic modal analysis and statistical energy analysis  

NASA Technical Reports Server (NTRS)

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.

Automating Frame Analysis  

SciTech Connect

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.

IAC - INTEGRATED ANALYSIS CAPABILITY  

NASA Technical Reports Server (NTRS)

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

Test Analysis Guidelines  

NASA Technical Reports Server (NTRS)

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."

Penetrating a wall of introspection: a critical attrition analysis  

NASA Astrophysics Data System (ADS)

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.

State Analysis Database Tool  

NASA Technical Reports Server (NTRS)

The State Analysis Database Tool software establishes a productive environment for collaboration among software and system engineers engaged in the development of complex interacting systems. The tool embodies State Analysis, a model-based system engineering methodology founded on a state-based control architecture (see figure). A state represents a momentary condition of an evolving system, and a model may describe how a state evolves and is affected by other states. The State Analysis methodology is a process for capturing system and software requirements in the form of explicit models and states, and defining goal-based operational plans consistent with the models. Requirements, models, and operational concerns have traditionally been documented in a variety of system engineering artifacts that address different aspects of a mission s lifecycle. In State Analysis, requirements, models, and operations information are State Analysis artifacts that are consistent and stored in a State Analysis Database. The tool includes a back-end database, a multi-platform front-end client, and Web-based administrative functions. The tool is structured to prompt an engineer to follow the State Analysis methodology, to encourage state discovery and model description, and to make software requirements and operations plans consistent with model descriptions.

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.

Cryogenic mirror analysis  

NASA Technical Reports Server (NTRS)

Due to extraordinary distances scanned by modern telescopes, optical surfaces in such telescopes must be manufactured to unimaginable standards of perfection of a few thousandths of a centimeter. The detection of imperfections of less than 1/20 of a wavelength of light, for application in the building of the mirror for the Space Infrared Telescope Facility, was undertaken. Because the mirror must be kept very cold while in space, another factor comes into effect: cryogenics. The process to test a specific morror under cryogenic conditions is described; including the follow-up analysis accomplished through computer work. To better illustrate the process and analysis, a Pyrex Hex-Core mirror is followed through the process from the laser interferometry in the lab, to computer analysis via a computer program called FRINGE. This analysis via FRINGE is detailed.

Amino acid analysis.  

PubMed

Amino acid analysis (AAA) is one of the best methods to quantify peptides and proteins. Two general approaches to quantitative AAA exist, namely, classical postcolumn derivatization following ion-exchange chromatography and precolumn derivatization followed by reversed-phase HPLC (RP-HPLC). Excellent instrumentation and several specific methodologies are available for both approaches, and both have advantages and disadvantages. This unit focuses on picomole-level AAA of peptides and proteins using the most popular precolumn-derivatization method, namely, phenylthiocarbamyl amino acid analysis (PTC-AAA). It is directed primarily toward those interested in establishing the technology with a modest budget. PTC derivatization and analysis conditions are described, and support and alternate protocols describe additional techniques necessary or useful for most any AAA method--e.g., sample preparation, hydrolysis, instrument calibration, data interpretation, and analysis of difficult or unusual residues such as cysteine, tryptophan, phosphoamino acids, and hydroxyproline.

Introduction: Regional Landform Analysis  

NSDL National Science Digital Library

This is chapter one of an on-line NASA book, Geomorphology from Space - A General Overview of Regional Landforms. It is divided into four sections and a conclusion. The first section, The Nature of Geomorphology, starts with the definition and continues with a description of the scales involved, fundamental concepts and the role of geomorphic studies. Types of Geomorphic Analysis is the title for the second section and it includes process studies and system analysis, climate geomorphology, and structural geomorphology. In the third section, after some remarks about quantification, maps and photographs are used to augment the demonstration of the role of space technology in large scale analysis and mapping. Prior to the conclusion there is a discussion of future directions, which includes global tectonic and climatic systems, analysis of ancient landscapes, and planetary geomorphology. The conclusion is followed by four plates including photographs, maps, and text that demonstrate the techniques described.
