This paper discusses some principles of critical discourse analysis, such as the explicit sociopolitical stance of discourse analysts, and a focus on dominance relations by elite groups and institutions as they are being enacted, legitimated or otherwise reproduced by text and talk. One of the crucial elements of this analysis of the relations between power and discourse is the patterns

Critical discourse analysis (CDA) and other forms of discourse analysis are regularly used to study identity, but rarely do researchers systematically compare and contrast them with other theories to identify exactly what a discursive approach contributes. In this paper, we take the example of a particular identity – the older worker – and systematically compare the contribution of CDA with

Using a critical discourse analysis, informed by poststructuralist theory, we explore the research phenomenon of coerced partnership. This lens allows us to pay attention to the social relations of power operating in knowledge generation processes, especially as they affect feminist researchers in adult education. We propose an alternative vision of partnership which politicizes the term partnership, attends to civil society,
Critical Discourse Analysis (CDA) has often proved fruitful in providing insights into the relationship between language and ideology. However, CDA is not without its critics. Constructive criticism has been offered by Stubbs, who suggests bolstering CDA by using a large corpus as the basis on which to make reliable generalisations about language use. Taking up that suggestion, this paper reports
In this response to a critique by Hugh Tyrwhitt-Drake of an earlier article (Flowerdew, 1997a), this paper discusses questions of description and interpretation in critical discourse analysis (CDA). In particular it discusses these issues under the following five postulates: CDA does not deal with ‘facts’; CDA is reflexive; CDA is open to multiple readings; CDA must be plausible; and CDA

Now more than ever, critical discourse analysis is urgently called upon to deconstruct the discourses of arrogant power and division which are largely secret for most citizens and which baldly contradict the discourses of populist solidarity propagated in an official democracy. This paper focuses on deconstructing two legal discourses, the craftily named “Patriot Acts,” designed to polarize the citizenry into

Critical discourse analysis (CDA) explores the role of discourse structures in constituting social inequality. Metaphorical structure, however, has received relatively little attention in explicit CDA. The paper aims to redress this by developing a coherent theoretical framework for CDA and metaphor. This framework adopts conceptual blending theory over conceptual metaphor theory, where the latter is perceived to be incompatible with
Since the publication in 1989 of Norman Fairclough's Language and Power and Ruth Wodak's Language, Power and Ideology, and the launch in 1990 of Teun van Dijk's journal, Discourse & Society, Critical Discourse Analysis (CDA) has not only grown into a major field of research in its own right but has also been widely adopted by researchers in a range

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.

Research ethics committees (RECs) are charged with adjudicating the ethical status of research projects, and determining the conditions necessary for such projects to proceed. Both because of their position in the research process and because of the controversial nature of ethical judgements, RECs' views and decisions need to be accountable. In this paper we use techniques of discourse analysis to show how REC decision letters 'do' accountability. Using a sample of 260 letters from three datasets, we identify a range of discursive devices used in letters written by RECs. These include drawing attention to: the process behind the decision, including its collaborative nature; holding the applicants accountable, by implying that any decision made by the REC can be attributed to the performance of the applicants; referring to specialist expertise; and calling upon external authorities. These tactics 'do' accountability by showing that routines of ethical assessment have been enacted, by establishing the factuality of claims, and by managing questions of fault and blame attribution. They may, however, also risk undermining legitimacy by failing to acknowledge the inherent contestability of ethical decision making or the limited nature of the cultural authority accorded to RECs, and thus may appear as an illegitimate exercise of power.

This article examines the way that critical discourse is written. It does so by considering the concept of nominalization.

However, the language used by critical analysts, as they explore nominalization, is revealing. They tend to use, and thereby instantiate,

This article discusses the extent to which methods normally associated with corpus linguistics can be effectively used by critical discourse analysts. Our research is based on the analysis of a 140-million-word corpus of British news articles about refugees, asylum seekers, immigrants and migrants (collectively RASIM). We discuss how processes such as collocation and concordance analysis were able to identify common

Shelters for abused women function within a broad context that includes intersecting social structures, policies, and resources, which may constrain and limit the options available to abused women and tacitly reinforce the cycle of abuse. This feminist, qualitative study combined in-depth interviews and focus groups conducted with 37 staff and four executive directors from four shelters in Ontario, Canada, along with a critical discourse analysis of salient policy texts. Together, the interviews and critical discourse analysis formed an integrated analysis of the dialectic between policy as written and enacted. The study findings illuminate the complexity of the system and its impact on women, shelters, and the community and highlight how specific types of social policies and various social system subsystems and structures, and system configuration, shape the day to day reality of shelter service delivery and impact outcomes for abused women and their children. Collectively, these findings offer direction regarding where these policies could be improved and provide a basis for shelters, policy makers, advocates, and the community to strengthen current services and policies, potentially enhancing outcomes for women.

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. PMID:20305746

Depression has received increasing attention as a significant public health issue over the past ten years, both in Canada and elsewhere in the industrialized west. During the same period, many of the social and economic policies adopted by governments in these jurisdictions have reflected neoliberal goals and orientations. The purpose of this article is to explore the points of contact between these two features of contemporary social and political life in the industrialized west, using the Canadian province of British Columbia as an empirical site. My analysis draws on the Foucauldian literature on governmentality in presenting a close reading of provincial government documents concerned with depression and mental health literacy that have been produced since the election of the Liberal Party to office in British Columbia in 2001. This analysis identifies discourses of "responsibilization" circulating in these documents, within which individuals, families, communities and workplaces - rather than publicly-funded services - appear as key resources in responding to experiences of mental distress. It also points to a number of strategies visible in the documents that work to align the interests of individuals and their practitioners in pursuing particular approaches to treatment with a governing interest in reducing public spending on services and supports. The article concludes by identifying a number of resistive discourses and proposing further research in a range of empirical contexts within which they may be evident. PMID:19427730

This study explored the discourse of mental illness contained within two UK newspapers over a 15-year period, excluding those stories that mentioned any reference to a diagnosis. Using frame analysis, a form of discourse analysis, ten distinct frames were identified and classified into "stories." These ten stories were categorized as: foreign, legal, drug, feature, trauma, tragedy, community care tragedy, social policy, inquiry report, and sports/celebrity stories. Each frame is described and the potential influence of such frames on both social policy and nursing practice is discussed. PMID:17957551

We set out to examine design conflict resolution tactics used in development of large information systems for health services and to outline the design consequences for these tactics. Discourse analysis methods were applied to data collected from meetings conducted during the development of a web-based system in a public health context. We found that low risk tactics were characterized by design issues being managed within the formal mandate and competences of the design group. In comparison, high risk tactics were associated with irresponsible compromises, i.e. decisions being passed on to others or to later phases of the design process. The consequence of this collective disregard of issues such as responsibility and legitimacy is that the system design will be impossible to implement in factual health service contexts. The results imply that downstream responsibility issues have to be continuously dealt with in system development in health services. PMID:19683068

This study examined the narrative discourse production and executive function (EF) abilities of 46 neuro-typical adults (18-98 years old). Two questions were addressed: Is the analysis of narrative structure sensitive to changes associated with aging? & What is the relationship between measures of narrative structure and EF? Narratives were elicited under two conditions and narrative structure was analyzed for the presence of organizing story grammar elements. Narrative structure was significantly correlated with age as well as linguistic and non-linguistic measures of EF. Factor analysis of story structure and EF variables yielded two factors reflecting constructs of output-fluidity and organizational-efficiency. These data suggest that narrative structure and EF represent aspects of goal-directed knowledge that are not bound by a traditional linguistic and non-linguistic division. Thus, narrative structure may represent a global and ecologically valid measure of goal-directed executive function knowledge that is also sensitive to changes associated with typical aging.

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

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

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

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.

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.

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

Contrary to most traditional approaches, ideologies are defined here within a multidisciplinary framework that combines a social, cognitive and discursive component. As ‘systems of ideas’, ideologies are sociocognitively defined as shared representations of social groups, and more specifically as the ‘axiomatic’ principles of such representations. As the basis of a social group's self-image, ideologies organize its identity, actions, aims, norms

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

This article examines the conditions under which epistemological shifts in medicine have shaped the history of apoplexy and stroke. Our intention is to understand how stroke medicine as a distinct branch of bio-medicine has emerged in its current form. In doing so, we draw on aspects of the work of Michel Foucault as they relate to fabrication of biomedical discourses. The past 300 years of the transformation of the condition is examined using Michel Foucault's analysis of medical history as instances of the changing spatialization of disease. While the adoption of this approach helped explain how medical practice was shaped by changing interpretations of the causes of apoplexy and stroke over the past few centuries, we also found that there were certain limitations to such an approach. Overall, however, we hope to show that an examination of the history of stroke medicine through a Foucauldian influenced lens can provide a useful understanding of its current circumstances as well as throw light on gaps in Foucauldian approaches themselves.

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

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

General Purpose Boundary Element Solution Technology (GPBEST) software employs the boundary element method of mechanical engineering analysis, as opposed to finite element. It is, according to one of its developers, 10 times faster in data preparation and more accurate than other methods. Its use results in less expensive products because the time between design and manufacturing is shortened. A commercial derivative of a NASA-developed computer code, it is marketed by Best Corporation to solve problems in stress analysis, heat transfer, fluid analysis and yielding and cracking of solids. Other applications include designing tractor and auto parts, household appliances and acoustic analysis.

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.
'Ought training analysis to be maintained?' This question, posed by Elias da Rocha Barros, chairing the IJP Congress of Training Analysts in 2001, is used by the author as a starting-point from which to present his ideas on the subject. The paper is divided into three parts. In the first the author presents a survey of the principal criticisms directed at training analysis since 1930. He examines a series of papers that have attracted the attention of those who have studied the subject, with the intention of describing the functional organisation of training analysis and its effects. The second part, based on the criticism presented in the first part, deals with the continuous pressure put on training analysis, in order to maintain its 'didactic' character. This transforms it into an autonomous reality, external to the pair, preceding and steering it. The author describes and discusses this structural aspect of its organisation. In the third part he presents two hypotheses about what factors nourish training analysis in spite of the thoroughness of the criticisms aimed at it. He describes training analysis as a fetish and as an ideological construct. As a fetish it is utilised by analysts to deny the limitations of analysis tout court, and as an ideological construct it is used to conceal its symptomatic character, naturalising it through its prescriptive institutional functioning. The author consequently replies to the initial question in the negative, even suggesting that all analysis discriminated as 'training analysis' ought to be abolished, leaving to the analysands the task of taking care of their analyses. This would be a measure that would also assist in the de-ideologisation of the Institution's mode of operation. The third part also contains a discussion and a criticism of a few suggestions addressed to training analysis in order to modify its functioning and character. PMID:14633428

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. PMID:16812400

After an 800-foot-tall offshore oil recovery platform collapsed, the engineers at Engineering Dynamics, Inc., Kenner, LA, needed to learn the cause of the collapse, and analyze the proposed repairs. They used STAGSC-1, a NASA structural analysis program with geometric and nonlinear buckling analysis. The program allowed engineers to determine the deflected and buckling shapes of the structural elements. They could then view the proposed repairs under the pressure that caused the original collapse.

This paper presents the criteria, previous nuclear experience in space, analysis techniques, and possible breakup enhancement devices applicable to an acceptable SP-100 reentry from space. Reactor operation in nuclear-safe orbit will minimize the radiological risk; the remaining safeguards criteria need to be defined. A simple analytical point mass reentry technique and a more comprehensive analysis method that considers vehicle dynamics and orbit insertion malfunctions are presented. Vehicle trajectory, attitude, and possible breakup enhancement devices will be integrated in the simulation as required to ensure an adequate representation of the reentry process.

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

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

Exploratory calculations were performed for several gas core breeder reactor configurations. The computational method involved the use of the MACH-1 one dimensional diffusion theory code and the THERMOS integral transport theory code for thermal cross sections. Computations were performed to analyze thermal breeder concepts and nonbreeder concepts. Analysis of breeders was restricted to the (U-233)-Th breeding cycle, and computations were performed to examine a range of parameters. These parameters include U-233 to hydrogen atom ratio in the gaseous cavity, carbon to thorium atom ratio in the breeding blanket, cavity size, and blanket size.

We describe the subject of Cosmic Microwave Background (CMB) analysis - its past, present and future. The theory of Gaussian primary anisotropies, those arising from linear physics operating in the early Universe, is in reasonably good shape so the focus has shifted to the statistical pipeline which confronts the data with the theory: mapping, filtering, comparing, cleaning, compressing, forecasting, estimating. There have been many algorithmic advances in the analysis pipeline in recent years, but still more are needed for the forecasts of high precision cosmic parameter estimation to be realized. For secondary anisotropies, those arising once nonlinearity develops, the computational state of the art currently needs effort in all the areas: the Sunyaev-Zeldovich effect, inhomogeneous reionization, gravitational lensing, the Rees-Sciama effect, dusty galaxies. We use the Sunyaev-Zeldovich example to illustrate the issues. The direct interface with observations for these non-Gaussian signals is much more complex than for Gaussian primary anisotropies, and even more so for the statistically inhomogeneous Galactic foregrounds. Because all the signals are superimposed, the separation of components inevitably complicates primary CMB analyses as well.

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

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.

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

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

Using cancer as an example and drawing on Pierre Bourdieu's concepts of field and on prolonged fieldwork in Danish general medical practice settings, we examine how discourses about what counts as legitimate help-seeking practices are negotiated in local clinical encounters. Overall, we identify competition between two discourses on help-seeking practices. This competition is present most when people seek help with unspecific, vague, or diffuse illness complaints, voicing uncertainty as to what counts as signs of illness, characteristic of proactive discourses emanating from global, scientific biomedicine. Such indistinct help-seeking conflicts with the dominant discourse in the local clinical setting and is characterized by an overt focus on identification of the chief complaint. The analysis illustrates how competing discourses may result in conflicting expectations to the clinical encounter and prove counterproductive to ensuring early diagnosis of cancer. PMID:25355457

This article analyzes discourse surrounding Arkansas's legislation requiring public schools to measure students' body mass index (BMI) annually and to send the scores to parents on children's report cards. Using poststructural feminist sensibilities, I explore the tensions experienced by parents, children, educators, and policymakers as this mandate was debated and implemented. The discourse illuminates salient issues about disproportionate disparities in health status that exist in communities with fewer resources, and the potentially unintended gendered consequences of health policies. I explain three dominant threads of discourse: How the economic costs of childhood obesity opened a policy window for the legislation; the presence of tensions between freedom and social control; and how BMI discourses inscribe ideological visions of bodies. Ultimately, the analysis offers insight into the discursive nature of policymaking and how class and gender are implicated in health interventions. PMID:21416419

The public's lack of understanding and the public's misconceptions about autism in China contribute to the underdiagnosis and undertreatment of the disorder and the stigma associated with it. Mass media are the primary channel through which people learn about autism. This article examines how leading newspapers in China covered autism in the 10-year period of 2003 through 2012 through a framing analysis. It finds that while autism has received increased media attention, it is increasingly framed as a family problem-family members are cited or quoted more than any other sources and the responsibility of dealing with autism is ultimately assigned to families. Autistic people are largely silenced unless they are autistic savants with special talents. The use of the scientific discourse and the human-interest discourse both decrease over time in percentage, while the use of other discourses such as the public relations discourse becomes more dominant.

Multipoint linkage analysis is commonly used to evaluate linkage of a disease to multiple markers in a small region. Multipoint analysis is particularly powerful when the IBD relations of family members at the trait locus are ambiguous. The increased power arises because, unlike single-marker analyses, multipoint analysis uses haplotype information from several markers to infer the IBD relations. We wish

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.

A research site with papers to download, links to researchers, a newsletter, etc. Analysis of Algorithms (AofA) is a field in computer science whose overall goal is an understanding of the complexity of algorithms. While much research is devoted to worst-case evaluations, the focus in these pages is methods for average-case and probabilistic analysis. Properties of random strings, permutations, trees, and graphs are thus essential ingredients in the analysis of algorithms.

Healthcare decision-making can be complex, often requiring decision makers to weigh serious trade-offs, consider patients’ values, and incorporate evidence in the face of uncertainty. Medical decisions are made implicitly by clinicians and other decision-makers on a daily basis. Decisions based largely on personal experience are subject to many biases. Decision analysis and cost-effectiveness analysis are systematic approaches used to support decision-making under conditions of uncertainty that involve important trade-offs. These mathematical tools can provide patients, physicians and policy makers with a useful approach to complex medical decision making. PMID:23966758

An electronic system for image analysis was developed on the basis of low and medium cost integrated circuits. The printed circuit boards were designed, using the principles of modern digital electronics and data processing. The system consists of modules for automatic, semiautomatic and visual image analysis. They can be used for microscopical and macroscopical observations. Photographs can be evaluated, too. The automatic version is controlled by software modules adapted to various applications. The result is a system for image analysis suitable for many different measurement problems. The features contained in large image areas can be measured. For automatic routine analysis controlled by processing calculators the necessary software and hardware modules are available.

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.

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

The sound field of a structural-acoustic enclosure was subject to experimental analysis and theoretical description in order to develop an efficient and accurate method for predicting sound pressure levels in enclosures such as aircraft fuselages. Asymptotic Modal Analysis (AMA) is the method under investigation. AMA is derived from classical modal analysis (CMA) by considering the asymptotic limit of the sound pressure level as the number of acoustic and/or structural modes approaches infinity. Using AMA, results identical to those of Statistical Energy Analysis (SEA) were obtained for the spatially-averaged sound pressure levels in the interior. AMA is systematically derived from CMA and therefore the degree of generality of the end result can be adjusted through the choice of appropriate simplifying assumptions. For example, AMA can be used to obtain local sound pressure levels at particular points inside the enclosure, or to include the effects of varying the size and/or location of the sound source. AMA theoretical results were compared with CMA theory and also with experiment for the case where the structural-acoustic enclosure is a rectangular cavity with part of one wall flexible and vibrating, while the rest of the cavity is rigid.

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.

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.

Half a century ago Hurst introduced Rescaled Range (R/S) Analysis to study fluctuations in time series. Thousands of works have investigated or applied the original methodology and similar techniques, with Detrended Fluctuation Analysis becoming preferred due to its purported ability to mitigate nonstationaries. We show Detrended Fluctuation Analysis introduces artifacts for nonlinear trends, in contrast to common expectation, and demonstrate that the empirically observed curvature induced is a serious finite-size effect which will always be present. Explicit detrending followed by measurement of the diffusional spread of a signals' associated random walk is preferable, a surprising conclusion given that Detrended Fluctuation Analysis was crafted specifically to replace this approach. The implications are simple yet sweeping: there is no compelling reason to apply Detrended Fluctuation Analysis as it 1) introduces uncontrolled bias; 2) is computationally more expensive than the unbiased estimator; and 3) cannot provide generic or useful protection against nonstationaries.

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

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.

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

Blood tests are an essential tool in clinical medicine with the ability diagnosis or monitor various diseases and conditions; however, the complexities of these measurements currently restrict them to a laboratory setting. P&P Optica has developed and currently produces patented high performance spectrometers and is developing a spectrometer-based system for rapid reagent-free blood analysis. An important aspect of this analysis is the need to extract the analyte specific information from the measured signal such that the analyte concentrations can be determined. To this end, advanced chemometric methods are currently being investigated and have been tested using simulated spectra. A blood plasma model was used to generate Raman, near infrared, and optical rotatory dispersion spectra with glucose as the target analyte. The potential of combined chemometric techniques, where multiple spectroscopy modalities are used in a single regression model to improve the prediction ability was investigated using unfold partial least squares and multiblock partial least squares. Results show improvement in the predictions of glucose levels using the combined methods and demonstrate potential for multiblock chemometrics in spectroscopic blood analysis.

The concept of emergy and its use for comparing with energy were discussed in this paper. Emergy was defined as the amount of available energy required directly and indirectly to make a product or services, and emergy analysis was based on the solar emergy units (solar emjoules). Emergy provided the methodology with a common basis for measuring the value of different kinds of energy, and for evaluating the contributions from nature and humanity. A comparison of emergy analysis with previous energy analysis was also performed. PMID:11813416

The distributed analysis experience to date at LHCb has been positive: job success rates are high and wait times for high-priority jobs are low. LHCb users access the grid using the GANGA job-management package, while the LHCb virtual organization manages its resources using the DIRAC package. This clear division of labor has benefitted LHCb and its users greatly; it is a major reason why distributed analysis at LHCb has been so successful. The newly formed LHCb distributed analysis support team has also proved to be a success.
Drug safety is not a matter for healthcare professionals alone. As actors, patients are also concerned, at three different levels: 1) with regard to their behaviour and choices of drugs, with a view to reducing adverse reactions, 2) with regard to the discourse sometimes used by doctors in relation to prescribed drugs, 3) with regard to the discourses of the pharmaceutical industry concerning how they use their drugs within the framework of self-medication. We will examine these aspects on the basis of data gathered in France during anthropological studies on drug use. Patients’ concerns about reducing adverse effects give rise to a series of behaviours relating to drug use. They start with the identification of what they regard as a risk inherent in the substances or linked to uncontrolled use of drugs and try to neutralize their risks by modifying or modulating the prescriptions in line with various parameters. They take into account dimensions as varied as: the nature of the prescribed drugs, the quantity, the dosage and the preservation of certain functions or organs, and follow their own rules of conduct in order to reduce risks. These dimensions bring into play both representations of the drug and representations of the person, and consider the effects or the risks of drugs in their physical, psychic, behavioural and social aspects.We consider here doctors’ discourse towards patients regarding the risks and possible effects of drugs, in particular the discourse of those who choose to hide the undesirable effects of drugs from their patients – or even to lie to them on this subject – with the aim of not jeopardizing the patient’s compliance. This situation involves comparing two logics: ethics of care versus ethics of information.Regarding the pharmaceutical industry’s discourse on self-medication and risks. Although it promotes self-medication on the basis of patients’ growing desire for autonomy and competency, the pharmaceutical industry has a discourse which stigmatizes the home medicine cabinet for reasons of safety, which in fact questions patients’ ability to use drugs properly. This analysis shows that the various behaviours and discourses relating to the risks of drugs are impregnated with symbolic, ethical and cultural logics. As a consequence, above and beyond works carried out on the question of pharmacovigilance, examining the issue of safe drug use involves studying the human (social and cultural) aspects which govern part of the discourses and practices relating to drug safety.

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

Trace element micro-analysis has evolved steadily since the early days of EPMA, yet remains an extraordinarily challenging subject. The enhanced capabilities of modern instrumentation, including the use of spectrometers with high X-ray collection efficiencies, high brightness electron sources, and improved stability all contribute to our ability to improve detection limits and analytical spatial resolution. Along with much improved software for data acquisition and analysis, recent progress in EPMA has made the trace realm more accessible than ever. High count precision can be obtained in order to easily bring analytical sensitivity into the single ppm range, but accuracy remains the greatest struggle. With the exception of the calibration, all sources of error encountered in major element analysis are magnified in trace analysis, and other sources become apparent where high spatial resolution is needed. Beam damage and charge effects are difficult problems in high sensitivity, high spatial resolution analysis, particularly in the analysis of insulators. Software can minimize some of the resulting effects on count rates during acquisition in order to improve accuracy, and analysts can empirically evaluate the conditions of analysis (count time, voltage, current, etc.) to try to minimize these effects. Trace analysis is fundamentally an exercise in background characterisation, and the acquisition and evaluation of background is a subject of developing methodology. Background curvature and interferences can result in considerable inaccuracy, but can be dealt with via detailed quantitative wavelength scanning or multi-point spectral acquisitions which allow proper regression of the background shape. In the absence of excellent quality trace element secondary standards of similar matrix to unknowns, blank testing and consistency standards can be used to test at least some aspects of the methods employed. Ultimately, the analyst must rely on accuracy evolving from application of the most rigorous protocols.

This paper critically examined the current scientific literature and conducted a concept analysis of anhedonia to provide a more accurate and lucid understanding the concept. As part of the concept analysis, this paper also provides model, borderline, related, and contrary examples of anhedonia. PMID:23706888
CIAO (Chandra Interactive Analysis of Observations) is the name for the suite of tools and applications developed at the CXC for the analysis of data from the Chandra X-Ray Observatory and other missions. We describe some of the uses of CIAO for the analysis of Chandra (and other) data. There are several innovative aspects of CIAO. The user has the choice of a command line or a graphic-oriented approach. the use of the CXC "Data Model" results in: file-format independence: users have the ability of reading and writing files in FITS, QPOE, and IMH format raw and column filtering and binning can be applied to input file for *all* CIAO tools and applications avoiding the need to generate subsidiary data files on disk all filters are recorded in the "data subspace" of output files which is then recognized in the subsequent analysis. CIAO, in its current release, includes several tools both instrument specific (for ACIS, HRC and grating analysis) and for generic data analysis (data manipulation, source detection, transforms & convolutions, response, and timing) and several applications (Prism, Chips, and Sherpa plus Firstlook, ToolAgent and Filter Window in beta version) .

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

Depression is an illness increasingly constructed as a gendered mood disorder and consequently diagnosed in women more than men. The diagnostic criteria used for its assessment often perpetrate and reproduce gender stereotypes. The stigma associated with mental illness and the gendered elements of depression suggest there are likely numerous discourses that position, explain, and justify help-seeking practices. This qualitative study explored men's discourses of seeking help for depression. The methodological approach was informed by a social constructionist perspective of language, discourse and gender that drew on methods from discourse analysis. We conducted individual in-depth, semi-structured interviews with 38 men with depression, either formally diagnosed or self reported. The analysis revealed five discursive frames that influenced the men's talk about help-seeking and depression: manly self-reliance; treatment-seeking as responsible independent action; guarded vulnerability; desperation; and genuine connection. The findings are discussed within a broader context of social discourses of gender, the limitations of current help-seeking literature and the evidence for how men seek help in ways that extend traditional notions of medical treatment.

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

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

Optimization techniques are increasingly being used for performing nonlinear structural analysis. The development of element by element (EBE) preconditioned conjugate gradient (CG) techniques is expected to extend this trend to linear analysis. Under these circumstances the structural design problem can be viewed as a nested optimization problem. There are computational benefits to treating this nested problem as a large single optimization problem. The response variables (such as displacements) and the structural parameters are all treated as design variables in a unified formulation which performs simultaneously the design and analysis. Two examples are used for demonstration. A seventy-two bar truss is optimized subject to linear stress constraints and a wing box structure is optimized subject to nonlinear collapse constraints. Both examples show substantial computational savings with the unified approach as compared to the traditional nested approach.
The Physics Analysis Workstation (PAW) is a high-level program providing data presentation and statistical or mathematical analysis. PAW has been developed at CERN as an instrument to assist physicists in the analysis and presentation of their data. The program is interfaced to a high level graphics package, based on basic underlying graphics. 3-D graphics capabilities are being implemented. The major objects in PAW are 1 or 2 dimensional binned event data with fixed number of entries per event, vectors, functions, graphics pictures, and macros. Command input is handled by an integrated user interface package, which allows for a variety of choices for input, either with typed commands, or in a tree structure menu driven mode. 6 refs., 1 fig.

The Centrifuge Rotor (CR) is a large life science experiment facility which will be installed in the International Space Station (ISS). It will provide artificial gravity of 2g or less by rotating up to 4 science habitats, and it will be the first such machinery to be used in space. To prevent vibration disturbance exchanges between the CR and the ISS, a soft 5 dof vibration isolation mechanism is used which cannot support the CR weight on the ground. Therefore, the CR on-orbit performance must be predicted by integrated analysis which must model all of the equipment including sensors, actuators, flexible structure, gyroscopic effects, and controllers. Here, we introduce the CR mechatronics, a verification procedure, and examples of the application of the integrated analysis which is based on the general-purpose mechanism analysis software ADAMS.

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

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

The Velocity Interferometer System for Any Reflector (VISAR) is a widely used diagnostic at Sandia National Laboratories. Although the operating principles of the VISAR are well established, recently deployed systems (such as the fast push-pull and air delay VISAR) require more careful consideration, and many common assumptions about VISAR are coming into question. This report presents a comprehensive review of VISAR analysis to address these issues. Detailed treatment of several interferometer configurations is given to identify important aspects of the operation and characterization of VISAR systems. The calculation of velocity from interferometer measurements is also described. The goal is to derive the standard VISAR analysis relationships, indicate when these relationships are valid, and provide alternative methods when the standard analysis fails.
The Flood Frequency Analysis module offers an introduction to the use of flood frequency analysis for flood prediction and planning. Through use of rich illustrations, animations, and interactions, this module explains the basic concepts, underlying issues, and methods for analyzing flood data. Common concepts such as the 100-year flood and return periods as well as issues affecting the statistical representation of floods are discussed. Common flood data analysis methods as well as an overview of design events are also covered. As a foundation topic for the Basic Hydrologic Science course, this module may be taken on its own, but it will also be available as a supporting topic providing factual scientific information to support students in completion of the case-based forecasting modules.

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

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

The portable Contamination Analysis Unit (CAU) measures trace quantifies of surface contamination in real time. The detector head of the portable contamination analysis unit has an opening with an O-ring seal, one or more vacuum valves and a small mass spectrometer. With the valve closed, the mass spectrometer is evacuated with one or more pumps. The O-ring seal is placed against a surface to be tested and the vacuum valve is opened. Data is collected from the mass spectrometer and a portable computer provides contamination analysis. The CAU can be used to decontaminate and decommission hazardous and radioactive surface by measuring residual hazardous surface contamination, such as tritium and trace organics It provides surface contamination data for research and development applications as well as real-time process control feedback for industrial cleaning operations and can be used to determine the readiness of a surface to accept bonding or coatings.

The Ensembl pipeline is an extension to the Ensembl system which allows automated annotation of genomic sequence. The software comprises two parts. First, there is a set of Perl modules (“Runnables” and “RunnableDBs”) which are `wrappers' for a variety of commonly used analysis tools. These retrieve sequence data from a relational database, run the analysis, and write the results back to the database. They inherit from a common interface, which simplifies the writing of new wrapper modules. On top of this sits a job submission system (the “RuleManager”) which allows efficient and reliable submission of large numbers of jobs to a compute farm. Here we describe the fundamental software components of the pipeline, and we also highlight some features of the Sanger installation which were necessary to enable the pipeline to scale to whole-genome analysis.

Techniques for analyzing the safety and reliability of analog-based electronic protection systems that serve to mitigate hazards in process control systems have been developed over many years, and are reasonably well understood. An example is the protection system in a nuclear power plant. The extension of these techniques to systems which include digital computers is not well developed, and there is little consensus among software engineering experts and safety experts on how to analyze such systems. One possible technique is to extend hazard analysis to include digital computer-based systems. Software is frequently overlooked during system hazard analyses, but this is unacceptable when the software is in control of a potentially hazardous operation. In such cases, hazard analysis should be extended to fully cover the software. A method for performing software hazard analysis is proposed in this paper.

This paper discusses the analysis of uncertainties in structural analysis of space crafts. Various sources for the discrepancies between prediction and measured response are identified. It is shown that only the effect of scatter of the structural parameters can be studied further by appropriate analysis tools. It is suggested to model uncertainties mathematically within the framework of stochas- tic analysis.

The structural analysis is a processing step during which graphs are extracted from binary images. We can decompose the structural analysis into local and global approaches. The local approach decomposes the connected components, and the global approach groups them together. This paper deals especially with the local structural analysis. The local structural analysis is employed for different applications like symbol

Exposure conditions in atomic oxygen (ESCA) was performed on an SSL-100/206 Small Spot Spectrometer. All data were taken with the use of a low voltage electron flood gun and a charge neutralization screen to minimize charging effects on the data. The X-ray spot size and electron flood gun voltage used are recorded on the individual spectra as are the instrumental resolutions. Two types of spectra were obtained for each specimen: (1) general surveys, and (2) high resolution spectra. The two types of data reduction performed are: (1) semiquantitative compositional analysis, and (2) peak fitting. The materials analyzed are: (1) kapton 4, 5, and 6, (2) HDPE 19, 20, and 21, and (3) PVDF 4, 5, and 6.
Zen's challenge for behavior analysis is to explain a repertoire that renders analysis itself meaningless—a result following not from scientific or philosophical arguments but rather from a unique verbal history generated by Zen's methods. Untying Zen's verbal knots suggests how meditation's and koans' effects on verbal behavior contribute to Enlightenment and Sam?dhi. The concept of stimulus singularity is introduced to account for why, within Zen's frame of reference, its methods can be studied but its primary outcomes (e.g., Sam?dhi and Satori) cannot be described in any conventional sense.

The MAJORANA DEMONSTRATOR is a large array of ultra-low background high-purity germanium detectors, enriched in 76Ge, designed to search for zero-neutrino double-beta decay (0???). The DEMONSTRATOR will utilize 76Ge from Russia, and the first one gram sample was received from the supplier for analysis on April 24, 2011. The Environmental Molecular Sciences facility, a DOE user facility at PNNL, was used to make the required isotopic and chemical purity measurements that are essential to the quality assurance for the MAJORANA DEMONSTRATOR. The results of this first analysis are reported here.

The elimination of ozone depleting substances, such as carbon tetrachloride, has resulted in the use of new analytical techniques for cleanliness verification and contamination sampling. The last remaining application at Rocketdyne which required a replacement technique was the quantitative analysis of hydrocarbons by infrared spectrometry. This application, which previously utilized carbon tetrachloride, was successfully modified using the SOC-400, a compact portable FTIR manufactured by Surface Optics Corporation. This instrument can quantitatively measure and identify hydrocarbons from solvent flush of hardware as well as directly analyze the surface of metallic components without the use of ozone depleting chemicals. Several sampling accessories are utilized to perform analysis for various applications.
Complete motion analysis laboratory has evolved out of analyzing walking patterns of crippled children at Stanford Children's Hospital. Data is collected by placing tiny electrical sensors over muscle groups of child's legs and inserting step-sensing switches in soles of shoes. Miniature radio transmitters send signals to receiver for continuous recording of abnormal walking pattern. Engineers are working to apply space electronics miniaturization techniques to reduce size and weight of telemetry system further as well as striving to increase signal bandwidth so analysis can be performed faster and more accurately using a mini-computer.
Ammonium nitrate production during the operation of the Defense Waste Processing Facility (DWPF) has been identified as a major problem. The accumulation of ammonium nitrate deposits in the vent system of the chemical processing cell has substantial safety implications and will require analysis of ammonium ions within DWPF process samples. As a part of the research and development of the DWPF at TNX, an ammonium analysis method developed by Dionex Corporation has been identified and confirmed to provide the required information. This memorandum describes the technical basis of the method, the accuracy and precision of the method, known interferences, and maintenance details.

Instrumental variable analysis is a recently propagated method to deal with confounding and to estimate therapeutic effects in observational studies. An instrumental variable is a factor which affects treatment but is not related to patient prognosis. A theoretical advantage of a well-chosen instrumental variable is that both measured and unmeasured confounders do not influence the effect estimator. Examples of instrumental variables previously used are regional differences in treatment and physician prescribing preference. Application of instrumental variable analysis seems most suited to large patient registries with considerable expected residual confounding in case standard analytical methods are applied.

The purpose of this analysis is to determine the structural response of the 21 pressurized water reactor (PWR) uncanistered fuel (UCF) waste package (WP) to a tipover design basis event (DBE) dynamic load; the results will be reported in terms of stress magnitudes. Finite-element solution was performed by making use of the commercially available ANSYS finite-element code. A finite-element model of the waste package was developed and analyzed for a tipover DBE dynamic load. The results of this analysis were provided in tables and were also plotted in terms of the maximum stress contours to determine their locations.

The process and apparatus for qualitative and quantitative analysis of the amino acid content of a biological sample are presented. The sample is deposited on a cation exchange resin and then is washed with suitable solvents. The amino acids and various cations and organic material with a basic function remain on the resin. The resin is eluted with an acid eluant, and the eluate containing the amino acids is transferred to a reaction vessel where the eluant is removed. Final analysis of the purified acylated amino acid esters is accomplished by gas-liquid chromatographic techniques.
